Positive Learning Essay

Introduction Student behaviours in schools have been perceived by researchers for years. Over the past twenty-five years, Sugai, (2009) states that Gallup Polls have specified, behavioural complications are on the top trials schools face. To establish and scan these behaviours, checklists of behaviours are available that included the most usual behaviours observed by te schools teachers (Algozzine, 2003). Such behaviours includes anxiety, disobedience, isolation, destructiveness and disruptiveness. Safran, Safran, & Barcikowski, (1985) states, such behaviours occupy teachers for an undue amount of time. Safran & Safran, (1984) reports that teachers normally spend sixty- ninety precent more time with misbehaving students than with the rest of the students. Johnson & Fullwood, (2006) states that teachers spend up to ninety precent more time with problematic students. Many new teachers have trouble dealing with persistent misbehaviour. They become exasperated because their previous responses had little impact. They spend substantial time distressing about the problem and often feel as if their authority and power is being challenged. A common way of consolidating behaviours is the division of internalising against externalising behaviours. Internalising behaviours such as anxiety, shyness, or inattentiveness mainly affect the student demonstrating the behaviour. Externalising behaviours such as fighting, aggression, and disobedience are outer-directed behaviours. It is essential to understand student behaviour from an eco-systemic viewpoint. This principle highlights the composite, unified and co-dependent type of relationships between a variety of relational, intra-personal and environmental factors that impact the everyday behaviours of teachers and students. The behavioural change in social systems does not take place in the direct approach of the positivistic custom. Instead, behaviours should be observed as cycles of communication. In other words, the students’ behaviour is assumed to be affected and dependent on the behaviours of other people around them. (De Jong. 2005). To learn the approaches and opinions of different people regarding student misbehaviour, a research was commenced through conducting informal interview of six people belonging to different groups in the society. The purpose was to get different views and perceptions on why students misbehave; interviewees included people from different groups such as practicing teachers, retired school teacher, parents, pre service teacher and a non-teaching professional. The interview consisted of several informal and open-ended questions in order to grasp the in-depth knowledge about various reasons of student misbehaviour and their solutions. The approach uses a series of questions intended to offer perspective on the student’s misbehaviour and assistance in creating responses. 2. 0 Participants: Following interviewees were selected for interview. Names have been kept confidential to maintain privacy. 1. Interviewee 1 (Female): is a full time teacher is her early 30’s. 2. Interviewee 2 (Female): is a pre-service teacher in her 20’s. 3. Interviewee 3 (Male): is a pensioned off school teacher in his late 50’s. 4. Interviewee 4 (Female): is a 38 years old mother of three children. 5. Interviewee 5 (Male): is a father of three children in his early 40’s. 6. Interviewee 6 (Male): is a non-teaching professional and postgraduate student in his early 30’s. During the interviews, many common themes regarding student misbehaviour, their reasons and impacts were discussed. Various researches and theories were also linked with the answers in order to analyse the root cause of such behaviours and the suitable responses. 3. 0 Understanding the Reasons for Difficult Behaviour: Understanding multiple causes of student misbehaviour can aid you to select the most applicable solution. Questions on physical, emotional and environmental factors were asked which helped in understanding the main grounds of problematic misbehaviours: 3. 1 Question – What are the physical causes of misbehaviour? Interviewee 1 suggested that the consumption of illegal Medication and Drugs by school students modify their behaviour in numerous ways. She once took students on an excursion, and one student arrived drunk showing extreme behaviours (drowsy, overly active). Students usually recall information when they are in the same state (drunk) as when they learned it (Eich, 1989). Interviewee 2 answered that students don’t take good care of their health and feeling unpleasant can make them irritable, although misperception and distraction may be more usual reactions. She also pondered that Fatigue is common in academic life and increases, when exams dates are near. When the pressure of exams increases, politeness is usually absent in students. Hearing and vision problems also result in student misbehaviour. A student with such debility may appear troublesome. Interviewee 3 answered that vision/hearing difficulty of student or even the teacher raises the risk of confusion thus leading to miscommunication and the possibility that student or teacher might get offended. 3. 2 Question – What are the major Emotional Challenges? Teachers have to choose if to get personally involved when emotional challenges are the reason for rude behaviour. Talking privately with associates or the counselling centre can benefit the teacher to choose when a student requires referral for professional assistance. Interviewee 6 specified that when school students reach an adults’ age, they’re usually given charge for their major decisions in life thus they might feel lonely once confronted with loss. Grief may be uttered as anger or guilt, depression and denial. Interviewee 3 believed that a small incident in the class (like forgetting the textbook) may activate a strangely big response and usually the teacher is merely an aim for the expression of the student’s sentiment. 3. 3 Question – What are the major Environmental Factors? Interviewee 1 discussed that class size and culture contribute to varying student’s behaviours. Big classes can buoy up a student or students to behave as if they were in a cinema or even a tv lounge. Interviewee further commented that supportive educational activities might aid in reducing the blockades that a big class creates among the teachers and the students. Every culture has a different standard regarding student’s unpunctuality to class or when it is suitable for a student to talk. If all every student is going to experience a specific cultural atmosphere after graduation, it may be easier to have classroom environment that matches with the work environment. Routine and Stimulation are other environmental factors identified by Interviewee 2 commented that excessive routine result in boredom, however too little creates confusion. A lot of motivation generates difficulties for the students who normally have trouble handling their activity level, and too little motivation results in disruption in the class. Interviewee 1 opined the importance of an unconventional learning environment. Some students require alternate flexible atmosphere but taking away students from the regular schoolroom should be the last alternative, and is grounded upon the belief that not all effective educational experiences happen in the classroom and thinking broadly about education is critical. 4. 0 Importance of behaviour management: 4. 1 Question – How important is behaviour management in effective teaching and learning? For many teacher and school front-runners in the past, a silent and disciplined classroom was the symbol of effective teaching. There is no doubt that regimented classrooms and schools enable effective teaching and the decent behaviour management skills are essential for teachers to perform the primary task of improving students’ performance and learning outcomes. Interviewee 3 stated that behaviour management is a key skill for both experienced and beginning teachers. Interviewee 6 specified specifies that it is brilliance in teachers that makes the utmost difference. Hattie’s research about the key impacts on the variance in student success examined the differences between experts, proficient and experienced teachers (Hattie, 2003). Interviewee 1 suggested that the student behaviour is indissolubly associated to the quality of the learning capability and teaching skills. Active pedagogics is acute to student engagement. She advised that good quality of teaching increases the student engagement and reduces behaviour matters. She further recommended that optimistic relationships between students and teachers are significant to encourage correct behaviours and attaining learning objectives. 5. 0 Role of parents: 5. 1 Question – How can parents contribute in improving the behaviour is students? Successful parent participation develops not only good student behaviour and attendance but also significantly affects student accomplishments. Parents can exhibit involvement at home by reading with their kids, assisting with homework, discussing school events and by attending functions or volunteering in classrooms. Being an experienced father, Interviewee 5 advised that parents are occasionally hesitant to get involved in school because they don’t have spare time or because they don’t speak smooth English. He said however â€Å"the biggest issue is the disconnection between the school and the parents†. Interviewee 4 on the other hand answered, â€Å"Parents consider that they are not welcomed. They often have had a lesser adequate experience with their own schooling†. However she firmly believed that parents should remain open and supportive with teachers and other school staff when dealing with issues of student misbehaviour. Retired school teacher Interviewee 3 recommended that school staff should mediate with parents while dealing with behaviour and misconduct issues. He also suggested that parents should back the school’s Student Behaviour Management Policy and should work with their children to assist them to understand their responsibility and obligations towards others. 6. 0 Effects of Teacher Gender: 6. 1 Question – How teacher gender affect the student behaviour? Interviewees were asked about the possible differences for teachers’ patience founded upon the gender of the teacher. Since both male and female teachers are present in the classrooms and the students are engaged in the classrooms with both genders, it is significant to recognise the characteristic differences. Teachers’ gender, teachers’ attitude, and the reporting of behaviour problem are found to have a connection (Ritter, 1989, Stake & Katz, 1982). Interviewee 3 believed that teacher tolerance and student behaviour have a give-and-take relationship, in that students’ behaviour influences the teachers’ patience levels for behaviours, teachers’ approach and opinion of the student, and the contagion influence of behaviour on the rest of the students in the class, resulting in academic achievement of the students. He also considered that students are more involved, behave more properly, and perform at a greater level when taught by teachers who shares their gender. On the other hand, Interviewee 6 suggested that the male teachers used more clarifications and general instructions than the female teachers. They also ask more questions and call for more student answers than female teachers. 7. 0 Conclusion: The interview with diverse group of people of both genders helped in identifying the main causes of student misbehaviours and efficient ways of addressing such behaviours. There are always students in classrooms who tend to meet their desires and wants through inappropriate behaviour. Having a range of alternatives (that are consistent with the needs and values of the teacher) can be exceptionally valuable when reacting to incidents of misconduct in complex classrooms. Both verbal and nonverbal communications are important when answering to persistent disobedience. Teachers should develop an â€Å"I mean it† demeanour by using firmness and clarity. Many student misconduct problems can be resolved by reorganising the environment. This might be done to ease proximity control, isolate students who cannot workout self-control, or eliminate students from an area where there are disruptions. Teaching students to adjust their own behaviour benefits students recognise their feelings and their wants and aiding them learn how to search for substitutes to unproductive behaviour. Teachers and parents need to be working together rather than being adversaries.

Building a Child’s Playhouse

This is an important issue because it concerns the welfare of children. Their mental health, wellbeing and recreation! The greatest parental happiness and the greatest parental worry are related to the joy and sorrow of their children. If you involve the children in building their own house, a Child’s Playhouse, you provide an outlet to them for their creative endeavors. But fortunately or unfortunately, commercialization of the Playhouse projects has robbed a big portion of creativity that really belongs to children.Yet, the concept of Playhouse still fascinates children and they feel a sense of involvement, in going through the literature, designs and colorful photographs concerning this project. Their involvement in the process of selection of the house thrills them. In the present day modern materialistic world, when there are too many unhealthy distractions for the children, to create social and home loving feelings in their minds is one of the solid achievements of conce pts like building a Child’s Playhouse. If such a house is at the countryside so much the better!It helps to cement the bonds between the children and Mother Nature with all her flora and fauna! If the children born and brought up in metropolitan cities were to stay in the Children’s Playhouse at the countryside, it will leave deep favorable impression on the formative minds. They will experience the difference between the concrete jungle and the real jungle of the birds and animals! Background information: Children are no ordinary market for the business giants. In fact, they are the main targets for food items and colas. The multinationals have staggering budgets running into millions of dollars to hook the children to their products.The business of costly, commercial Playhouses and Cottages has been taken over by the business community. â€Å"Do-It-Yourself Playhouse Building Plans, Build a new Playhouse, Play Fort, Kid's Cottage, or Child-Size Backyard Cabin for yo ur kids. These plans are crafted by experts and by the editors of magazines like Family Handyman, Garden Gate, WOOD Magazine, Workbench and more. They come with clear illustrations and step-by-step instructions to make your work easy. Most of the plans include complete material lists. (Summerwood Products)That’s about the real Playhouse, let us say, the architect’s playhouse, which is like a housing project, with the stamp of children’s enjoyment program. Naturally, the main emphasis of such types of Playhouses is what maximum happiness and sporting activities the house can provide for the children! In the construction of such Playhouses, the role of children in the process of construction and finishing is very limited, because every thing is related to the house arrives in a packed container/parcel, and the assembling part of such ‘engineering units’ also belongs to the company-trained personnel.Sometimes, children are mere observers; only they get the visual joy of the house being assembled by experts in front of their eyes. It is not possible to provide clear cut dimensions of a playhouse . The design and the area can be anything. The definition of a playhouse is, â€Å"a small structure that looks like a house and is big enough for children to play in. †(Collins Cobuild English Language Dictionary) The children did build their Playhouses and found their own channels of happiness since time immemorial. But the models and designs have undergone metamorphic changes.In olden days, children built Playhouses using mud, tree leaves and branches, to play and enjoy the games created by them. They were low budget or no-budget playhouses, created for the sake of temporary enjoyments, during week ends and during holidays. There was more joy and less capital investment in such Playhouses. The study of the problem: During my study of the Playhouse phenomenon, I found the mushroom growth of playhouses of all sizes, varieties and d esigns. It has become a fashion with the city folk to own a Children’s Playhouse at the countryside. It is ‘construction activity’ in full swing!The Child’s Playhouse has almost become synonymous Holiday Homes built for employees by Banks, Multinational Corporations etc. The original purpose of building the play house for children was altogether different. It was by the children, for the children and to the children! If it is a real playhouse for children, the joy and the activity element in building the Playhouse, needs to be the exclusive property of the children. If the children remain present during the inaugural ceremony of a newly constructed playhouse by their rich parents, well, it is still a playhouse but much of the joy essence is not in it.Let the parents spend some quality time with their children. Have a close look at this observation by a father happily observing his child engaged in building something of her own! â€Å"Later, while recoveri ng from the shopping experience, I didn't notice Ana busy in her room–until I was called for a â€Å"fitting. † Resting on green sponge soles was a converted shoe box, with painted laces hooked around colored paper clips. My new â€Å"shoe† had everything: bagel stickers on its sides and sports-card toes, rivaling the best in-store models.Children in today's â€Å"media generation† often don't make things at home, and they often construct objects only in cyberspace. Computer games, and even the new Logos[R], come with hefty instruction manuals for constructing very specific pre-determined forms. Art teachers need to consider the importance of children making things, building by hand, constructing their own objects without formulas or patterns. † (Szekely, February 2001) Cost of building a Playhouse and material required: This is a highly hypothetical question and no fixed answer can be given.It all depends upon one’s requirements and plan. Wh at is important is the involvement of children in the construction of the house. That is the real Playhouse. It can be a low-budget simple cardboard playhouse, created by appliance boxes. Children need not be told how cut holes, windows and doors and install air conditioners! You can provide the children with dozens of boxes so that they can build a real big playhouse with all the furnishings like curtains, wall decorations and even a table tennis court! They can paint the house and make the interior decorations of their choice.And if you wish to go for real Play Houses, all that you have to do is go through the various catalogues and do the selection in consultation with your children, the real masters of the Play Houses! The material used for such Playhouses is of high quality and as per approved specifications. The Playhouse comes with a warranty of 5 years or more. The total cost of the Playhouse will be as per your budgetary allocations. Conclusion and recommendations: Children have endless possibilities and confidence. The parents and the teachers have a great responsibility to wean away the children from the net games.This is not to say that the net games are totally bad. But moderation in this area is the need of the hour. Children, love physical activity! Their real joy is in creativity, involvement, create playthings, alter playthings and destroy playthings. Building playhouses needs to be an important part of the syllabus for children, where the teachers should be mere observers. Watch and note what the children do, left to themselves. They can be given broad hints. The mention made about the responsibility of teachers and parents is just not an academic issue. Spending maximum time with your children is the social need of the present times.The distractions for the children and the younger generation are too many. Involvement of the parents in the activities that interest the children is one way to control them in the positive way. Staying in a play house and engaging with the children is good for both! Finally, try to awaken the hidden genius within your child. By allowing him to construct and have his own Play House! Word count: 1317. . Works Cited Collins Cobuild English Language Dictionary.

Pros and cons of sex educations in school system Essay

Pros and cons of sex educations in school system - Essay Example ‘If they know about they will do it; knowledge is dangerous.’ It’s no surprise that the far right fanatical religious factions are advocating this concept much the same as it has for many centuries. Fortunately, the vast majority of Americans have taken the responsible viewpoint that not teaching sex-ed in schools would be indefensible as knowledge is power and the lack of it, especially in this instance, would be harmful to the children all parents wish to protect. According to the World Health Organization, there is no data suggesting that such courses promote increased levels of sexual activity. In addition, abstinence-only programs were substantially less effective than wide-ranging sex-ed classes which include safe-sex practices along with abstinence. These conclusions came at the end of a study conducted on 35 sexual education programs throughout the world. Nationwide research by Planned Parenthood and the Guttmacher Institute produced the same deductions. M ost parents understand that increased awareness promotes only increased responsibility as, according to a 1999 study conducted by Hickman-Brown Research, 93 percent of the American population wants sex to be taught at least during high school while 84 percent say it should be taught during middle school. Most parents acknowledge the reality that young people are sexually active at an earlier age than previous generations. Today, two-thirds of U.S. high school students have experienced sex by their senior year. These teenagers are contracting and spreading sexually transmitted diseases, in part, because of their lack of knowledge. People under the age of 24 are responsible for 65 percent of all sexually transmitted infections contracted in this country according to the Kaiser Family Foundation and the Centers for Disease Control (Masland, 2006). The factions opposed to sex education have imposed at least some of their will on the rest of society and the children have suffered for it. Sex education classes in America’s public schools have been scaled back so as to not offend the vocal minority. What parents want and think their kids are learning falls well short of what is actually being taught. Parents simply want their kids to know the dangers and how to avoid them, just as in any other aspect of their lives. â€Å"Contrary to common wisdom, when it comes to sex education, parents want it all, from abstinence to homosexuality,† said Steve Rabin, senior vice president of the Kaiser Family Foundation (Levine, 2000). The study by the Kaiser Foundation surveyed over a thousand secondary school kids, parents and sex-ed teachers along with more than 300 school principles. The majority of parents, according to the study, believe that discussions regarding rape were essential in sex-ed curriculum and that teaching about homosexuality is imperative as well. In addition, parents also want schools to discuss abortion, pregnancy, sexually transmitted disease s and the use of contraception. Rape is a reality and parents, it has been proven, realize that the more information their girls acquire regarding prevention and how to deal with the psychological aftermath can be nothing but helpful. As with the other subjects parents wish to be covered in school, the more knowledge, the better off their kids will be. Unfortunately, these important aspects of sexual education are sorely lacking in schools despite parental wishes and in opposition to what research has

Organizational Change Interview Paper Essay Example | Topics and Well Written Essays - 1250 words

Organizational Change Interview Paper - Essay Example Schuh (2000) has mentioned the needs of differentiation strategy for successful marketing. In his opinion, â€Å"using a common product, price, distribution and promotion program on a worldwide basis--does not seem adequate considering the differences in market conditions† (Schuh, 2000). In order to realize the extent of changes happening in the organizational world, I decided to interview a top official in Coca Cola Company. One of my friends is currently working in Coca Cola Company’s marketing department and he helped me in meeting, Jack Nicholas, one of the sales managers of Coca Cola Company. This paper is written based on my interview with Coke’s sales manager, jack Nicholas. My first question was about the mission, vision, and values of the Coca Cola Company at present and in past. Jack told me that the vision and mission of Coke has changed a lot over the past five years period. Earlier, Coke had a standardized vision and mission statement for the entire world. However, Coke realized that keeping same vision and mission for the entire world is meaningless since the requirements of different regions or countries are different. Focus on needs of our consumers, customers and franchise partners, Get out into the market and listen, observe and learn, Possess a world view, Focus on execution in the marketplace every day, Be insatiably curious etc are some of the values strictly kept in the market by Coke (Vision, Mission and Values, 2011) Jack explained the above point more in detail. He told me that most of the global countries and regions are different, politically, economically, culturally and socially. In other words, the requirements and the purchasing abilities of the people are different everywhere and it is illogical to keep same mission and vision for the extremely diverse population in the world. It was difficult for Coke to operate in communist countries earlier because of the strong opposition Coke faced in those countries bec ause of its origin in America. For example, China was reluctant in allowing American companies to enter its soil earlier. However, at present China is accepting foreign direct investments with both hands. The above changing foreign policies and economic policies of China cannot be neglected by Coke. In short, political and economic climate in the world are facing drastic changes at present which forced companies to change their vision and mission to cater the needs of the changing world. My second question was about the major determinants of change in Coca Cola Company. Globalization was the major cause of changes happening in Coke according to Jack. He has told me that the business principles changed a lot as a result of globalization. Currently Coke is trying to expand its territories with the help of modern business principles and merger and acquisition is accepted as the major mode of entry to foreign countries. For example, Coke acquired ThumsUp from India as part of their busi ness expansion in India. Coke realized that local knowledge is essential for conducting successful business in a foreign market. In order to acquire local knowledge, acquisition or merger is accepted as the best strategy by Coke. Political, economic and legal climate are other major determinants of change accepted by Coke to expand its business in different territories. Jack

Rape, what to do while being raped, and reporting rape Essay

Rape, what to do while being raped, and reporting rape - Essay Example This paper is going to discuss what to do and how to report rape so that the rapist can be convicted for his shameful act. The main instinct would be to scream, shout, kick, punch and yell at the rapist. This helps when you are in crowd and your shouting may bring help to you. When you start getting the feeling in the first place that somebody is trying to harass you sexually by touching or through any other cues, you must first of all tell him loudly to leave you alone or shout â€Å"Help†. Then if you are attacked, then it is natural that you will and have to shout for your sake. Kick him in his groin hard enough to get his hands off you. But what if you are in a desolate place? Rapists like deserted places where the victims cannot call for help or where there are no witnesses. In that case, screaming will do no good and the better thing would be to submit to the rapist to keep him from getting more violent and hurting you more. Men usually like to see terror they cause in women’s eyes and they enjoy it. So, when there is no help around, it would be better to stay calm so that you can come up with some idea to end this up. But if you decide to fight which is natural, then hit the rapist if you have something sharp in your hand like a bottle or anything you can grab and hit that will make him change his mind from continuing. Another good tip is that you should pretend as if you are going to vomit on the rapist’s face (Crislip). You can also try biting his hands or ears which will cause him enough pain to get off you. You can also tell him that you are suffering from AIDS! After knowing this, he will sure ly not wish to rape you or will discontinue even in the middle of the rape. Though vulgar to state here, but a sure tip to get him off you is to grab his scrotum and squeeze it hard till he yells for his life. You can do this by pretending as if you are enjoying the act and then grabbing his sensitive area and hurting it hard. Whether you

Depletion of the High Plains Aquifer (paper 5) Essay

Depletion of the High Plains Aquifer (paper 5) - Essay Example In America there is an adequate amount of agricultural land to, for the most part, sustain our population. Gutentag’s observations indicate that the farmers of this agricultural land in turn rely heavily on whatever water resources they can exploit to bolster production. Irrigation is the major issue causing a depletion of the water table in this region, posing a major threat to the Ogallala aquifer (Gutentag). The recharge is considered a factor of interest in this paper. Cities located on the aquifer will also be considered as possible factors. This paper will examine the origin of the Ogallala aquifer, its depletion, consequences of this depletion and the possible measures which can be taken to curb its depletion. Besides, I will also address the counterarguments to this depletion. Before evaluating whether depletion in aquifers is anthropogenic or natural it would benefit to address where the ground water came from. Multiple factors play the contributory role in the establ ishment of underground water among which are glacial melt, underground water movement through infiltration and percolation (MacNeill; McDermott &. Horne).â€Å"Glaciers account for more than scenic alpine landscapes. Glacial deposits form fertile soils in the Unites States and southern Canada and many ground-water aquifers†(Smith 438). 21,000 years ago a massive glacier covered most of the United States. As this glacier receded to what now is the glacier covering Greenland, it ground the surface rock, creating fertile soil in its wake as well as saturating the aquifers below. Since then there has been small amounts of recharge from rain and snow absorption, but the vast majority was accumulated from the last ice age (Hutson, Barber, Kenny, Linsey, Lumia, and Maupin). During the thawing process, when the snow water melts, some melt water find their way to the underground channels though the soil pores and rock joints. This seeping water upon reaching the aquifer often settle i n this region to form the underground punk. Besides, the glacial moraine forms fertile grounds for agricultural practices, a common phenomenon which ushered in the south west region after the universal glacial recession, the geologic ice age, about 250- 350 million years ago. The presence of fertile soil and convenient access to groundwater below the surface has created an agricultural oasis in the Midwest, but the many straws stuck into the aquifer are draining it at an alarming rate. Ground water in aquifers is typically discharged through natural and anthropogenic means. â€Å"Permanently flowing streams intersect the water table and gain discharge from ground water flow. Streams not in contact with the water table are dry during periods of limited rainfall. When streams above the water table receives runoff, some of the flow is lost to ground water through infiltration through the bed† (Smith 418). In nature, without anthropogenic effects, an individual would note that Aq uifers are constantly ‘full’, giving off whatever rainfall or snowmelt acquired in the form of discharge into local streams. This is almost never the case currently, due to the result of the anthropogenic effect on the aquifers. As humans have tapped into the aquifers, they have dropped

Mutual Exclusion in Multiprocessor Systems Essay

Mutual Exclusion in Multiprocessor Systems - Essay Example This issue can be resolved by employing an appropriate mutual exclusion of the programs and their resources so that no two programs would request for the same resource if one of them is using it already. Therefore, under many occasions, it is important for the programs to recognise the usage of any of the resources and should provide for resolving the same at the earliest possible opportunity. This paper aims at studying the possible mutual exclusion algorithms that are employed in a uni-processor system and in a multi-processor system. With reference to the execution of a code or a section of a code, these should not be executed by two processes at the same time. They are to be critical code. Assuming that there will be multiple processes running on multiple processors, there could be more than one process requesting for the same resource. It is important for all the requesting processes to allow one process to run at a time. Mutual exclusion algorithms should ideally provide lee-way for the following options: 1. Freedom from deadlock: Locking is the simplest way of avoiding repeat use of critical processes. While locking can be effective for stopping execution of a job, when another one is running, it might not be fool proof. For instance, if process 1 locks a critical section A for its use and it makes use of section B for execution of the section A and suppose process 2 locks section B and for its execution if it needs section A which is locked already by process 1, then a dead lock occurs. (Figure 1). Any successful mutual exclusion should also avoid deadlocking. 2. Freedom from Livelocking: This is a desirable requirement for the algorithms offering the mutual exclusion. This would ensure that there is no permanent lock existing for any process; a corollary of the deadlocking. But it also says that if some process wants to enter a critical section, one such process will enter the critical section. This implies that the one

I dont know - Essay Example But in the U.S., there is no discrimination based upon sex. Here, women can get driving licenses and drive their cars. When I was able to get a driving license, I came to realize the real meaning of equality. For instance, in Saudi Arabia, I will be difficult for me to get a driving license. So, I learned the essence of freedom as a person with a driving license. Besides, driving a car changed me a lot. For instance, I can drive my own car without further assistance from others. This is really important to me as an individual from a male dominated society. To be specific, from driving a car, I learned to be the part of the mainstream society and it changed my attitude towards the U.S society. As an individual, getting engaged is an important event in my life. One can see that my education in the U.S. with scholarship helped me to have a suitable alliance. For instance, I made use of my education in the U.S. as an opportunity to be free from male domination. To be specific, most of the male dominated societies hesitate to allow independence to the womenfolk. The thing that I learned from getting engaged is that education can help one to choose the most suitable individual. Now I feel so happy because I am independent to take decisions on my own. Seligman opines that â€Å"Happiness in the present moment consists of very different states from happiness about the past and about the future, and itself embraces two very distinct kinds of things: pleasures and gratifications† (102). Now I realize that happiness is interconnected with individual freedom and liberty. When a human being is free from external pressure, there exists high scope for development in future. Gett ing engaged changed me a lot because I realize that a suitable alliance is one of the factors of happiness in life. As an individual from the Middle East, especially from Saudi Arabia, my life as a student in U.S was so interesting. My education in the

Security Threats and Defenses Essay Example | Topics and Well Written Essays - 500 words

Security Threats and Defenses - Essay Example It is therefore the responsibility of any success oriented organization to enlighten its employees on the underlying security threat. An ethical, well goal oriented team is always desired. Information security is a major concern to all organizations. It ought to be part of every organization’s internal controls and operations. These controls ought to be internalized in a way that the employees are made to realize that violation of security puts them at a greater risk. These services to make employees feel their loyalty is crucial to the success of the business. In addition, information security need be given priority and adopted as a distinct value in any institutional culture governing staff behavior. It is therefore necessary to review security policies by offering training forums to employees. Another way of promoting security is by way of regularly reviewing security guidelines to ensure they are relevant an in line with the expected performance. Communication between the management and the employees ought to be health for security purposes. This aids in that employees can report underlying identified security threats before they occur. Healthy communication patterns not only boost security, but also save the company from incurring unnecessary costs arising from security compromises. Fraudsters have devised many forms of interfering with the security systems of organizations. For instance, there has been intensive use of ignorance of controls by employees. This occurs in organizations where employees think some process are long and bureaucratic and hence, want a quick way out of it. Ignorance is no defense as it compromises the security of an organization (Hadnagy, 2011). It also occurs where employees are not well briefed on internal controls and information security patterns of an organization.

Zenecas DTC Advertising of Nolvadex Essay Zeneca is largest pharmaceutical and agricultural/industrial chemical company in United States. In 1999 breast cancer was the most frequent diseases were found in American women, about 175,000 cases of breast cancer were diagnosed and about 43,500 women were died due to the breast cancer. According to the breast cancer prevention trial (BCPT), 45% reduction in breast cancer cases came through the use of Nolvadex. In November 1998 due to the new indications from the Food and Drug Administration (FDA) for the use of Nolvadex, Zeneca had decided to start direct to consumer advertisement campaign for Nolvadex. Findings In finding report will find over all performance of Zenecas advertisement campaign. This report will also look at the ethical issues which were raised in the case study, issues which were raised by activist groups and recommendations for managing the activists protests. 1. 1-Uncertainties from medical o Lack of sufficient data form breast cancer preventing trial physicians were worried about the side effects of Nolvadex, because the women who have high risk of breast cancer who might die if they do not take drug but for healthy women Nolvadex were not suitable from their point of view. According to physicians past experiences, Nolvadex lowered the breast cancer risk in women age 35 or more but increase the risk of other diseases in healthy women like endometrial cancer and other minor side effects like blood clots in the legs and lungs, hot flashes flushing, irregular menstrual periods, dizziness, headaches, fatigue, loss of appetite, vomiting and irritation of skin around the vagina. o Same studies like breast cancer preventing trial came from British and Italian studies which failed to show that tamoxifne was associated with a cancer risk reduction benefit They give assurance that women can both learn and control their risk, when, in fact, the risk model that is being promoted by Zeneca has been rightfully criticized by biostatisticians. The drug that Zeneca is promoting is one whose short tern benefits in healthy women are in question, and whose long term risks among healthy women are still unknown. o Some doctors were argued that side effect was too serious to prescribe for women who did not have breast cancer. They were asking to add more advisability of using the drug to lower the risk of breast cancer. These physicians wanted to wait for more data regarding Nolvadex and comparing trial of Nolvadex with Eli Lillys Evista which some believed that safer then Zenecas Nolvadex. 1. 2-Uncertainties from regulatory o According to Food and Drug Administration (FDA) there were some problem with exact language that contained in the new labelling e. g. Zeneca wanted to use word Prevention for describing the Nolvadex but FDA was not agree because labelling was lack of enough data on what happened to the women in the study after five years of treatment FDA was disagreed with Zenecas ads. because they were lack of brief summary regarding the risk and other information about Nolvadex. They wanted to disclose those information in advertising campaign o Zeneca had made the video for unbranded advertisement which was included full information of breast cancer and about Nolvadex but FDA had argued that video was heavily branded and lack of fair balance between benefits and risks of Nolvadex o Zeneca was required to include a four-part disclaimer (including side effects) when ever the word Nolvadex comes in video FDAs Division of Drug Marketing, Advertising and Communication (DDMAC) reviewed the information material in advertising campaign and determine that they are false or misleading and lacking fair balance and they are full of product and in violation of the Act for the above reasons o Zeneca was failed to discuss the Gail Model Risk Assessment Tool in the print advertisement or brochure which damage the importance of an accurate risk assessment and side effects. Due to lack of mortality data FDA approved the Nolvadex for women at high risk of breast cancer but did not approved it for use as a breast cancer prevention agent and they refer Nolvadex as a risk reduction therapy 1. 3-Zenecas decisions on DTC campaign When Zeneca decided to do the DTC campaign for Nolvadex, they had done some research before advertising campaign but this research only focusing on womens thinking about breast cancer. They did not involve patients, physician, advocacy group and activist groups in ad campaign. Another draw back came from The Food and Drug Administrations regulation and guide lines which were keep changing during the development of direct to consumer advertising campaign. FDAs guide lines were influencing the Zenecas decisions on advertisement campaign. They were trying to follow FDAs regulations but other side they had ignored physicians and activist groups during the development of DTC advertisement campaign and later Zenecas campaign was concern by these independent groups. They had tried to make branded ad but due to the regulatory it was required full information regarding drug. They were feared that if they disclosed the information regarding drugs benefit and risk it would affect the advertisement effectiveness. Thats why they decided not do the branded advertisement. Zenecas unbranded advertisement was less concern by regulatory in terms of disclosing drugs information but more concern by activist groups because of incomplete information. Also assumptions in advertisement were not appropriately taken into consideration e. g. women care their body shape more then health or you can only get breast cancer if you have family history which were concerned by regulatory and activist groups. In brief Zeneca had taken inappropriate decision regarding DTC advertisement campaign. They did not involved patients, physicians, distributors and advocacy groups before developing DTC campaign. They had followed the rules and regulations of FDA but failed to take physicians, patients and activist groups in confidence.

Efficacy of Herbal Shampoo and Pesticides for Head Lice

Efficacy of Herbal Shampoo and Pesticides for Head Lice Efficacy of herbal shampoo of Garcinia dulcis(Roxb.) Kurz ( Clusiaceae) compared with chemical pediculicides for head lice treatment in Thailand   Ã‚   Sirawut Sittichok1 and Mayura Soonwera1   Abstract Currently, alternative pediculicide from plant are need for head lice treatment because of chemical over-the -counter have lost in efficacy due to increasing resistance of head lice( Pediculus humanus capitis ) to chemical over-the-counter worldwide .As the result , this study was to assess the efficacy of herbal shampoo of Garcinia dulcis (Roxb.) Kurz (Clusiaceae) compared with two chemical pediculides ( carbaryl shampoo ; Hafif shampoo ®; 0.6% w/v carbaryl and permethrin shampoo ; Scully Anti-Lice shampoo ®; 0.5% w/v permethrin) and baby shampoo (Care baby shampoo ®) for head lice treatment. In vitro study used the filter paper method with three doses of 0.002, 0.003 and 0.006 ml/cm2 of each treatment for assessing the toxicity of each treatment on mortality of nymph and adult of head ice. The results revealed that as the concentration of treatment increased from the doses of 0.002, 0.003 and 0.006 ml/cm2, the mortality rate of nymphs and adults of head liceincreased. Moreove r,the most pediculicidal activity was shown by the dose 0.006 ml/cm2 of G. dulcis shampoo at 10 min,showing 100% mortality of nymphs( LT50 value of 0.2 min and LC50 value of 0.00001 ml/cm2) and adults(LT50 value of 0.7 min and LC50 value of 0.001 ml/cm2). In addition, these results showed more effective on pediculicidal activity than carbaryl shampoo (LT50 values ranged from 6.3 to 10.1 min), permethrin shampoo (LT50 values ranged from 28.9 to 61.8 min) and baby shampoo (LT50 values ranged from 77.3 to 87.1 min). For the results of in vivo test showed that G. dulcis shampoo also exhibited 100 % of cure rate after the 2nd and 3rd treatments and these result was more effective for head lice treatment than two chemical pediculicides and baby shampoo( cure rate ranged from 0 to 96.7%). Consequently, the results of this study pointed that G. dulcis shampoo showed high potential for to be used as alternative pediculicide for head lice treatment of children in Thailand . Keywords: Pediculus humanus capitis, herbal shampoo, Garcinia dulcis , carbaryl shampoo, permethrin shampoo Corresponding author: M. Soonwera (à ¯Ã¢â€š ¬Ã‚ ª) and S. Sittichok Introduction   Ã‚   Pediculosis capitis (head lice infestation), caused by the wingless insect, Pediculus humanus capitis De Geer (Phthiraptera: Pediculicidae), is one of the most ectoparasitic infestation of human worldwide and affecting mostly children with more than a million per year worldwide. However,Each year ,nearly five million of children and parent are newly infested ( pediculosis) with this ectoparasitic insect (Pilger et al., 2010 and Roberts, 2002). The some researchers reported that, an annual rate of 15 million infestation with head lice and cost of 150 US$ per treatment in the USA, the overall annual cost of head lice treatments are estimated to be US$ 2,250 million . In addition, over-the-counter pediculicides sales in the USA were estimated at >US$ 240 million per year in 1997 and increased to > US$ 350 million per year in 2003 (West , 2004). Furthermore, the American infested children are lost 12-24 million school days per year by No Nit Policy (the policy for infested schoolchildr en, before they can return to schools ,they to be free of nits ,nymphs and adults of head lice )( National Association of School Nurses,2016) . So, annual economic loss owing to missed workdays and schooldays by parents and infected children who have to stay home estimated of US$ 4-8 billion to the countrys economy (Ko and Elston, 2004 ; Leung et al.,2005). However, numerous case of head lice infestations has been reported throughout the world (Eroglu et al., 2016; Doroodgar et al., 2014). Generally , the neurotoxic insecticides (such as malathion, cabaryl, lindane, permethrin) used as pediculicides for head lice treatment worldwide and head lice resistance to neurotoxic pediculicides have occurred in several parts of the world. (Centers for Disease Control and Prevention, 2016,Devore et al.,2015 and Devore and Schutze ,2015). The alternative pediculicides for head lice treatments are critical needed. However ,alternative pediculicides from plants or herbs have attracted a good pedi culicides to develop the new potion for head lice treatment, because of their low mammalian toxicity and save for children, mode of action that are not neurotoxic and the possibility that they will have a low potential for the development of head lice resistance (Rassami and Soonwera, 2013; Strycharz et al.,2014). In addition, Gallardo et al.(2012) and Toloza et al.(2006) reported the pediculicidal activities of essential oils from Geranium maculatum ( geranium) ,Myrcianthes cisplatensis ,Eucalyptus cinerea , Eucalyptus viminalis and Eucalyptus saligna .The lotions based on essential oils from lavender ,peppermint and eucalyptus exhibited pediculicidal properties( Audino et al.,2007).Moreover, herbal shampoos of Averrhoa bilimbi ,Clitoria ternatea,Myristica fragrans , Plectranthus amboincus, Tacca chantrieri, Zingiber cassumunar and Zanthoxylum limonella exhibited high pediculicidal activities ( Rassami and Soonwera,2013). The pediculosis among Thai preschool children(3-5 years old) and Thai primaryschool children(6-12 years old) ,especially the children in the rural area of Thailand were high level with more than 50% and normally the frist option for head lice treatment of them were chemical control. Unfortunately, mostly the chemical pediculicides in Thailand market are neurotoxic pediculicides ( such as pediculicides consist of lindane, malathion ,carbaryl and permethrin ) and several products have lost in efficacy due to increasing resistance of head lice to chemical pediculicides (Rassami and Soonwera, 2013). Moreover ,the high toxic effects of chemical pediculicides to children were recorded in several part of the world.The mode of action of chemical pediculicides to children were toxic to the childrens respiratory and nervous systems(Eisenhower and Farrington,2012). Consequently , the infested children in Thailand needed the effective and safety pedicilicides for head lice treatment, the aim of this study was to evaluate the pediculicidal activity of herbal shampoo from Garcinia dulcis (Roxb.) Kurz (Clusiaceae) against head lice and compared pediculicidal activity with two chemical pediculicides (carbaryl shampoo (Hafif shampoo ®, 0.6% w/v carbaryl), permethrin shampoo (Scully Anti-Lice shampoo ®, 0.5% w/v permethrin)) and one baby shampoo (Care baby Shampoo ®) in vitro and in vivo test. In addition, G. dulcis plant is known as Maphutin Thailand.This plant specie is an edible plant and fruit and use asmedicinal plant in Thailand. All part of G. dulcis have long been used in traditional Thai medicines such as expectorant , antipyretic, antitoxic, anti-inflammatory and tonic. The mature fruit of G. dulcis also can be used for soft drink , jam or fruit paste (Fig.1, Deachathai et al., 2005 and Lim, 2011). For this reason, herbal shampoo from G. dulcis is the selected herbal shampoo in this study. We will hope that G. dulcis shampoo is the good , effective and safety he rbal product for to be used as alternative pediculicide for Thai infested children especially rural children in Thailand. Materials and Methods Collection of Garcinia dulcis fruits and herbal shampoo of Garcinia dulcis The leaves, flowers, raw and mature fruits of this plant were collected from Bangkok and Nakhonratchasima province (North-eastern part of Thailand),Thailand during May-June 2016 (Fig. 1) for identification by the taxonomist of Faculty of Agricultural Technology, King Mongkuts Institute of Technology Ladkrabang (KMITL), Bangkok, Thailand. The extracts from mature fruits of Garcinia dulcis were used for herbal shampoo by medicinal plant scientist of Medicinal Plant Laboratory, Faculty of Agricultural Technology, KMITL. All herbal shampoo of Garcinia dulcis for this research was provided free of charge from Medicinal Plant Laboratory. Chemical shampoo and baby shampoo: Carbaryl shampoo (Hafif shampoo ®, 0.6% w/v carbaryl) : this chemical product was a common pediculicide in Thailand . This product was purchased from IDS Manufacturing Co. Ltd., Pathumthani province, Thailand and used as positive control. Permethrin shampoo (Scully shampoo ®, 0.5% w/v permethrin) ,It was the chemical product and usually used as pediculicide in Thailand. It was purchased from Sherwood Chemical Manufacturing Co. Ltd., Chacheangsao province, Thailand and used as positive control. Baby shampoo (Care baby shampoo ®) ,this baby shampoo was purchased from Colgate-Palmolive (Thailand) Ltd. 700/362, Bangna-Trad km57, Amphur Muang, Chonburi Province 20000, Thailand and used as negative control. Collection of head lice This study was approved by the Ethics committee of the Faculty of Agricultural Technology, King Mongkuts Institute of Technology Ladkrabang (KMITL), Bangkok, Thailand ( 2559-01-04-013) and in collaboration with the directors and teachers of thee primary schools at Bangkok, Thailand. However, the 250 of schoolchildren were infested with head lice and to collaboration in this study. All head lice ( 3rd nymphs and adults) were collected by the anti-head lice combs from collaborating schoolchildren . Moreover, the protocol for head lice treatment of collaborating schoolchildren ,allowed using only the anti-head lice combs during 30 days.Afterward, nymphs and adults of head lice were separated by carefully removing them from teeth of the combs into clean insect boxes (18.023.0x5.5 cm) and were transported them to Entomological Laboratory, Faculty of Agricultural Technology, KMITL, within 30 min. All nymph and adults of head lice were identification by Entomologist of our Faculty, as Pedic ulus humanus capitis De Geer (Pediculidae: Phthiraptera). The P.humanus capitis specimens to be used as the further reference specimens for further research and were kept in the museum of Faculty of Agricultural Technology , KMITL. Bioassay The bioassay used filter paper contact to evaluate the pediculicidal activity of four shampoos (G dulcis shampoo, carbaryl shampoo ,permethrin shampoo and baby shampoo) and the distrillation water( negative control) in vitro. This bioassay was adapted from Rssami and Soonwera( 2013) and Soonwera(2016) and 30 min after head lice collection,the bioassay was stared. The doses of 0.002 ,0.003 and 0.006 ml/cm2 of G. dulcis shampoo, carbaryl shampoo, permethrin shampoo, baby shampoo and distillation water ( negative control ) were applied to the filter paper (Whatman ® No1, 4.8 cm diameter) and after drying for 30 s, each filter paper was placed on the bottom of a petri dish (5.0 cm diameter). Afterward, selection under the stereomicroscope (Nikon ® Type 102) for the10 nymphs (the 3rd stage nymphs) or the adults of head lice and were placed them on each filter paper. The mortalities of nymphs or adults on each filter paper were recorded under dissecting stereomicroscope at 10, 30 and 60 min. In addition, the criteria for mortality of all head louse was defined as the complete absence of any vital signs from the external and the internal structures of head lice such as legs ,antennae ,digestive system, nervous system and muscular system with or without stimulation by micro-paintbrush (Rassami and Soonwera , 2013).The criteria for the pediculicidal activity was adapted from Sonwera(2016) was defined as the LT50 value of treatement was less than 1.0 min. All treatments were replicated 10 times. The mortality data was statistic analyzed with Duncans multiple range test (DMRT) using SPSS for windows version 16.0. The LT50 and LC50 values were calculated by Probit analysis. In vivo test, The total number of 120 infested (pediculosis) schoolchildren between the ages 5 to 12 years from three primary schools in Ladkrabang district, Bangkok, Thailand were selected to participate in the experiment. In addition, the criteria for pediculosis was defined as the presence of at least on the alive egg or nit (alive nit was within 0.5-1.0cm of hair from the scalp and tan to coffee colour with an intact operculum) , the living nymph or the living adult. All infested schoolchildren in this study allowed using only the anti-head lice comb for head lice treatment and during the experimental period, they had not been treated head lice with any chemical pediculicides or any herbal shampoos. The 120 infested schoolchildren were randomly and separated into four groups (10 schoolchildren per group per school).However, all treatment was replicated three times, as follows; Group 1 treated with G. dulcis shampoo Group 2 treated with carbaryl shampoo (Hafif shampoo ®, 0.6% w/v carbaryl) Group 3 treated with permethrin shampoo (Scully shampoo ®, 0.5% w/v permethrin) Group 4 treated with baby shampoo (Care baby shampoo ®) However, all infested schoolchildren in the groups were treated with G. dulcis shampoo, carbaryl shampoo, permethrin shampoo and baby shampoo by applying 20 ml of each shampoo to a wet hair and scalp per head for 5 min and then rinsed off with the clean water. The cure rate (no pediculosis) was recorded of 1 day after the 1st application . In addition , the second application was started 1 day after the first application for the infested schoolchildren (pidiculosis)in the groups ,after the first application.They were treated with the tested shampoos for cured and recorded the cure rate . The third application was started 1 day after the second application, the infested schoolchildren( pediculosis) in the groups ( after the 2nd application) were treated with the tested shampoos for cured and recorded the cure rate . In addition , the criteria for cure rate was defined as the complete absence of the alive nit, the living nymph and the living adult of head lice on hair and scalp of scho olchildren and criteria for pediculicide was defined as 100% of cure rate. Results The efficacy of four tested shampoos ( G. dulcis shampoo, carbaryl shampoo, permethrin shampoo and baby shampoo) on mortality of 3rd stage nymphs of P. humanus capitis as shown in Table 1 . The most effective in pediculicide was shown by the 0.006 ml/cm2 of G. dulcis shampoo caused 100% mortality of nymphs at 10 min, LT50 value of 0.2 min and LC50 value of 0.00001 ml/cm2 . Moreover , this results exhibited significant in pediculicide (LT50value less than 1.0 min) over carbaryl shampoo ( 82.0% mortality,LT50value of 6.3min) ,permethrin shampoo( 42.0%mortality ,LT50value of28.9 min) and baby shampoo ( 35.0% mortality ,LT50 value of 77.3 min). However, at the dose of 0.003 ml/cm2 revealed that G. dulcis shampoo caused 100% mortality at 30 min and LT50 values ranged from 2.2 min , followed by carbaryl shampoo , permethrin shampoo and baby shampoo with 78.0 , 48.0 and 39.0 % mortality and LT50 values of 8.2 , 55.8 and 79.2 min ,respectively. At the dose of 0.002 ml/cm2, G. dulcis shampoo exhibited 100% mortality at 30 min and LT50 value of 3.7 min followed by carbaryl shampoo , permethrin shampoo and baby shampoo with 77.0 , 44.0 and 37.0% mortality and LT50 values of 9.1 , 58.5 and 87.1 min , respectively. However , based on the LC50 values indicated the order of the effective in pediulicide of tested shampoo as G. dulcis shampoo ( 0.00001 ml/cm2) > carbaryl shampoo( 0.002ml/cm2) > permethrin shampoo ( 0.1ml/cm2) > baby shampoo( 1.8 ml/cm2). However , no mortality of all nymph at all dose in distillation water group was observed ,so distillation water was nontoxic to all nymphs during the testing time The results of in vitro test of P. humanus capitis adults as shown in Table 2 and Fig. 3. At the dose 0.006 ml/cm2 of G. dulcis shampoo was the most toxic to head lice adults with 100% mortality at 10.0 min, LT50 value of 0.7 min , followed by carbaryl shampoo , permethrin shampoo and baby shampoo with72.0 , 41.0 and 32.0 % mortality and LT50 values of 6.7 , 35.2 and 79.6 min, respectively . Moreover, the mortality results of head lice adults of G. dulcis shampoo showed significant pediculicidal activity (LT50 50 values ranged from 6.7 to 35.2 min) and baby shampoo (LT50 value of 79.6 min). At dose of 0.003 ml/cm2 revealed that of G. dulcis shampoo also showed the most toxic to head lice adults with 100% mortality at 60 min and LT50 value of 3.3 min , followed by carbaryl shampoo , permethrin shampoo and baby shampoo with77.0 , 60.0 and 41.0 % mortality and LT50 values of 9.5 , 38.5 and 80.6 min, respectively . In addition , G. dulcis shampoo at the dose of 0.02 ml/cm2 caused 84.0 % mortality of head lice adults at 60 min and LT50value of 4.4 min ,followed by carbaryl shampoo , permethrin shampoo and baby shampoo with70.0 , 50.0 and 31.0 % mortality and LT50 values of 10.1 , 61.8 and 87.6 min, respectively. Moreover, based on LC50 value pointed that of G. dulcis shampoo was the highest effective in pediculicide to head lice adults showing LC50 value of 0.001ml/cm2, followed by carbaryl shampoo (0.002 ml/cm2), permethrin shampoo (0.2 ml/cm2) and baby shampoo ( 2.2 ml/cm2) ,respectively. Meanwhile , no mortality of adults were observed in distillation water( negative control). All adults in negative control survived and normality throughout the testing periods.In addition, statistical analysis of head lice nymphs and adults showed significant differences between G. dulcis shampoo and two chemical shampoos( carbaryl shampoo and permethrin shampoo). In addition, nymphs(LT50 values 0.2 to 87.1 min) were more susceptibility to all tested shampoo than adults (with LT5 0 values 0.7 to 87.6 min). In vivo results as shown in Table 3 and Fig.2 ( the first application) , 4( the second application) and 5( the third application) , the results for the first application revealed that G. dulcis shampoo exhibited the highest cure rate(97.6%) and the lowest pediculosis(3.3%) ,followed by carbaryl shampoo and permethrin shampoo with the cure rate of 73.3 and 16.7 % and pediculosis of 26.7 and 83.3 % ,respectively. Meanwhile,Care baby shampoo ®as the negative control showed 0% of cure rate and Pediculusis of 100%(100% of schoolchildren still had head lice on the head ) after the first application. The results for the second application showed that G. dulcis shampoo also exhibited the highest of cure rate (100%) and 0% of pediculosis followed by carbaryl shampoo and permethrin shampoo showed cure rate of 83.3 and 23.3% and pediculosis of 16.7 and 76.7 %, respectively. However , 100% pediculosis of all schoolchildren were recorded in the Care baby shampoo ® treatment. Therefore, the Ca re baby shampoo ®( the negative control ) was not effective in pediculicide for head lice treatment. The results of the third application, G. dulcis shampoo also exhibited the most effective in pediculicide to head lice showing 100% of cure rate. Moreover, G. dulcis shampoo showed more effective in pediculicide( 100% of cure rate) than carbanyl shampoo ( 90.0% cure rate,10.0% pediculosis) and permethrin shampoo( 27.8% cure rate , 72.2% pediculicides). However,Care baby shampoo ® also showed nonpediculicidal activity with 100% of pediculosis in tested schoolchildren. All the result of this study pointed that G. dulcis shampoo was the highest efective pediculicide( 100% of cure rate,LT50 value less than 1.0 min) for controlling head lice. The G. dulcis shampoo exhibited more effective in pediculicide than carbaryl shampoo , permethrin shampoo and Care baby shampoo ®. In addition, after 1st, 2nd and 3rd applications, none of schoolchildren showed negative side effect such as the red spot of the scalp and neck, burning sensation or irritation of the scalp. Discussion Our data in this study, G. dulcis shampoo showed the highest toxic to nymph and adult of head lice with 100% mortality at 10 min, LT50 value 50 values ranged from 0.00001 to 0.001 ml/cm2, in vitro test. Moreover, this result showed more effective pediculicide than carbaryl shampoo (Hafif shampoo ®), permethrin shampoo (Scully shampoo ®) and baby shampoo (Care baby shampoo ®). In addition , in vivo test, G. dulcis shampoo also showed toxicity to head lice and was more effective pediculicide for head lice treatment than two chemical and baby shampoos with 100% cure rate after the second application. Meanwhile, two chemical shampoos showed the cure rate of 27.0-90.0% after the third application. However,Care baby shampoo ®as negative control in this research showed 0% of cure rate and 100% pediculosis( the tested schoolchildren still had head lice after the third application). In addition, baby shampoo cannot be used as pediculicide for head lice treatment of schoolchildren, it was a mild formulation to gently cleanse baby hair without sting babys eyes. As the result, baby shampoo is not suitable for controlling head lice. However, Rassami and Soonwera (2013) reported the high effective in pediculicide of herbal shampoos for head lice treatment of schoolchildren in Thailand such as herbal shampoos of Phyllanthus emblica (Euphorbiaceae) and Zanthoxylum limonella (Rutaceae) and Acorus calamus (Acoraceae) and the results for head lice treatments of all herbal shampoo were more effective in pediculicides than carbaryl and malathion shampoos. However, carbaryl shampoo (0.6% w/v carbaryl) in this study was a common pediculicide in Thailand market for head lice treatment. The toxicity of carbaryl shampoo to children ,after application of this chememical shampoo for head lice control also recorded in several parts of the world. Moreover, this chemical shampoo was the hazardous shampoo for infested children , especially the children less than 5 years of age and it high toxic to childrens nervous system(Eisenhower and Farrington,2012). Moreover, carbaryl pediculicide showed decreased efficacy against head lice and head lice resistance to carbaryl pediculicide has been reported in several countries such as Australia, UK and USA (Durand et al., 2012 and Eisenhower and Farrington,2012). Since 1995 In the UK, since 1995 carbaryl pediculicide has been available only on prescription, because of concerns about possible carcinogenic effect ( any substance that produces cancer). However,in the UK, 1% carbaryl product in aqueous formulation is still recommended for UK head lice guidelines (Durand et al., 2012). On the other side, permethrin shampoo (0.5% w/v permethrin; Scully shampoo ®) showed 30-75% mortality of nymphs and adults of head lice (LT50 values ranged from 28.9 to 61.8 min) in vitro test and exhibited 16.7-27.8% of cure rate (72.2-83.3% of pediculosis in schoolchildren ) in vivo test and these results were less pediculicidal activities than G. dulcis shampoo. Moreover, in this study, permethrin shampoo showed the low efficacy in pediculicide may be explained by nymphs , adults and nits of head lice were resistance to permethrin shampoo . However, permethrin shampoo is the common and preferred shampoo of Thai infested children especially for the urban children for head lice treatment , because permethrin shampoo exhibited a rapid effect in mortality of head lice. Unfortunately, the toxicity of permethrin shampoo to children and head lice resistance to permethrin shampoo were recored in serveral parts of the world . Moreover, permethrin shampoo was the neurotoxic product for children ,it showed high toxic to nerve cells of children. The side effect after treated with permethrin shampoo were the itching , rash and burning of the childrens scalp and corneal damage of childrens eyes (Allen and Cox, 2016 and Ko and Elston, 2004 ). However ,permethrin shampoo also toxic to the head lices nervous system , it destroyed the nerve cells of head lice , resulting in incapability and mortality of head lice (Eisenhower and Farrington, 2012 and Cute et al., 2008). However, pyrethroids products such as permethrin and D-phenothrin have been registered as pediculicides since the 1970s and have been widely common as over-the-counter pediculicides since the 1980s (Devore and Schutz,2015) .The Food and Drug Administration (FDA) of USA approved permethrin pediculicide can be used in patients as young as 2 months of age and older and pregnant women ( American Academy of Pediatrics,2015). Consequently, caution should be used in patients with ragweed allergy, because respiratory difficulty or asthmatic episodes may occur with permethrin use in such patients (Devore et al.,2015 and Eisenhower and Farrington, 2012). Moreover, The clinical and parasitologic resistance to pyrethroids was first reported in France in a randomized controlled trial and followed by additional reports from Europe (Czech Republic, United Kingdom and Denmark), the Middle East (Israel), North (United States), and South (Argentina) America, Asia (Japan), and Australia ( Durand et al.2012, Ko and Elton,2004 and West,2004). However, G. dulcis shampoo showed the most effective pediculicide in vitro and in vivo in this study. The alternative pediciculicides from herbs such as neem exhibited high potential for head lice treatment ( Abdel-Ghaffar et al., 2016). In addition, herbal shampoo base on 10% of long pepper (Piper retrofactum) fruits of Acorus calamus, Phyllanthus emblica and Zanthoxylum limonella extracts showed highly effective pediculicides for head lice treatment of infested schoolchildren in Ladkrabang area, Bangkok, Thailand, and these results were more effective in pediculicide than carbaryl and permethrin shampooes ( Rassami and Soonwera,2013 ; Soonwera, 2016). However , Audino et al.(2007) reported the lotions containing essential oils from eucalyptus , peppermint and lavender showed more effective pediculicide than the commercial lotion in the Argentina market. Moreover, the commercial pediculicide products based on plants and herbs such as Licatack shampoo ® (extract of grapefruit), Aes culo Gel ® L (active compound noted Cocos nucifera oil), WashAway Laus shampoo ® (active compound noted neem extracts), Nopucid Bio Citrus ® (active compound noted bergamot essential oil), Paranix ® (active compound noted essential oils from coconut, anise, and ylang ylang), Puressntiel ® (active compound noted essential oils of lavender, clove, tea tree, geranium, vegetable oils of cocos, calophyllum, jojoba, sunflower, almond, ricin) showed high effectiveness against head lice (Abdel-Ghaffar et al., 2016 and Soonwera, 2016). However, G. dulcis is known as an Asian medicinal plant, belongs to the family Clusiaceae (Guttiferae) and is widely distributed in Thailand and other Southeast Asian countries (Malaysia, Indonesia, the Philippines (Deachathai et al., 2005 and Pinkaew et al., 2012).This plant is locally known as Maphuut in Thailand, Mundu in Indonesia and Malaysia. The G dulcis is an edidible plant and evergreen tree (size of 5 to 20 m high ,Fig 1). The fruit with ye llow and white latexes and fruit latexes were turns to lightly brown on exposure to the air. The bark is dark brown and rough and much branched. The leaves are large and leathery with dark green color and leaves are opposite, simple large, ovate, and oval to belong up to 10-30 cm long by 3-15 cm wide(Fig 1). The fruits are oblate to round and the diameter of fruit size of 5.5-8.5 cm (Fig.1). The fruit peels are smooth, green when immature and tuning yellow or yellow-dark when ripe and usually 1 fruit has 1 to 5 seeds . The fruit peel is thin and soft when ripe while the fresh is pulpy and yellow in color. However, soft yellow flesh has a butter-like consistency and slightly acidic but pleasant to eat. The raw fruit is too sour to be eaten but local Thai people used raw fruit of G. dulcis to improve the taste in sour and spicy soup, Thai curry , spicy soup , pickles and used mature fruits in jam ,butter or sherbert (Abu-Baker et al., 2015 and Lim, 2011). Furthermore,all part of G. du lcis has long been used in traditional Thai medicine to treat human diseases such as fever,cold ,antipyretic and detoxification (Deachathai et al., 2006 and Pinkaew et al., 2012). The stem bark has been used traditionally as anti-inflammatory agent and crushed extract from the bark is used for cleaning wounds while the fruit juice was used as expectorant for coughs, and scurvy. The extracts of G. dulcis roots are used for antipyretic, anti-toxic and detoxification (Deachathai et al., 2005; Lim, 2011 and Lamai et al., 2013). The traditional medicine of Indonesia have been used seeds and leaves of G. dulcis to treat human disase such as thyrocele , lymphatitis and parotitis and the extracts of G . dulcis fruits and leves to treat of anti-HIV activity , antiviral, ant-bacterial, anti-inflammatory, antitumor , anti-cancer and anti-oxidant (Abu-Bakar et al., 2015; Lamai et al., 2013; Hutadilox-Towatana et al., 2007; Pang et al., 2009; Pinkaew et al., 2012 and Tuansulong et al., 2011). However, G. dulcis is an edible plant in Thailand and also used as the medicinal plant in traditional Thai medicine and G.dulcis shampoo also exhibited the high effective in pediculicide to controlling head lice.Therefore, herbal shampoo from G. dulcis in this study is the effective and safe pediculicide and after application with G dulcis shampoo , the tested children were no-side effect such as the red spot or irritarion on the scalpes of the chidren.This herbal shampoo is suitable to be used as alternative herbal pediculicide for head lice treatment, especially for infested children in rural area of Thailand and may be the good and safe pediculicide for children of rural area of Southeast

Comparing the Cites where I have Lived :: comparison compare contrast essays

Compare and Contrast Cites where I have Lived I have opinions of all the places I have lived. Each place has its advantages and disadvantages, and I am not sure if there is any place that really fits me well. In this essay, I will examine the bad and good aspects of some of the places I have lived. Then, I will compare what I consider to be "ideal" conditions with the good aspects of those places where I have lived. Lastly, I will choose the place that I think is best for me. I was born in Taipei, and I lived there for a great part of my life. I consider it to be my hometown, and I cherish many of the memories I have form there. I like the people and places in Taipei, especially some of its unique characteristics, like the night markets. The pattern of the city is familiar to me, and the streets are always full of people shopping. Taipei does, however, have some bad aspects. It was a severe air pollution problem, and heavy traffic jams are commonplace. The city just has too many people packed into too little space. Its many buildings are packed closely together, and this just makes the overcrowding problem worse. After living in Taipei during ny childhood and teenage years, I moved to southern Taiwan to attend college. The town I lived in was much less populated than Taipei, and that was nice. But, it was very hot there and that was a big problem. They also did not have a large shopping center, so buying nice clothes was difficult. I felt like I could not look fine or pretty. Unlike Taipei, this town had no fine restaurants or shops either. On the good side, this town was wide open. There was lots of space and the natural scenery was just beautiful. Because it was not so crowded, and traffic was not a problem, there was not much pollution either. I like this because it was easier to keep healthy. When I finished my work at a hospital in Taiwan, I moved to the university of Woollongone, in Australia. I went there to study conversational English.

The Important Role of Transcendentalism in American History Essay

The Important Role of Transcendentalism in American History In 1830, a movement known as Transcendentalism began to gain popularity in America. Representing an idealistic system of thought, "strength, courage, self-confidence, and independence of mind"1 were some basic values admired by the followers of the Transcendental movement. Transcendentalists opposed many aspects of their government, where they felt "many unjust laws existed."2 Therefore, they became the leaders of many modern reform movements. Transcendentalists also had a major affect on their society. Transcendentalism became a "powerful force for democracy."3 Originating in the area in and around Concord, Massachusettes, Transcendentalism was recognized as having an "underlying relationship to the Romantic movement as a whole."4 Three of the most obvious or well known sources or origin of Transcendentalism are neo-platonism, German idealistic philosophy, and certain Eastern mystical writings which were introduced into the Boston area in the early nineteenth century."5 Transcendental beliefs focused on "the importance of spirit over matter."6 Ralph Waldo Emerson, a well known Transcendentalist, felt that "all men aspire to the highest, and most of them spend their lives seeking money and power only because they see nothing higher."7 Followers also believed in a spiritual hunger, or the need to find themselves one with the world. In addition, they believed in "an ascending hierarchy of spiritual values rising to absolute good, truth, and beauty."8 Transcendentalists also believed in a supreme being, the Oversoul, and felt that "if the Oversoul is all powerful and at the same time good, then evil does not exist."9... ...reconciled few of them."19 It was never united by a set program. Transcendentalism was comprised of the various interests and labors of many different personal concepts. Therefore, there were many conflicting values which made it an unsteady system to follow. At the time of the Transcendentalism movement, "it preached, practiced, an idealism that was greatly needed in a rapidly expanding economy."20 However, soon people began to find other, more comprehensible means of dealing within society. Therefore, they began to turn away from Transcendentalism. However, even though Transcendentalism is non-existent as a whole today, many of its ideas, values, and morals are still present in many of the religions and beliefs of today's society. In conclusion, Transcendentalism will always be present in the world, it just will not have as obvious a presence.

Animal Testing :: essays research papers fc

Animal testing is an issue in today's society that, whether anyone realizes it, does affect each of us. Such as transplants, vaccines, and medicine. Nearly each and every one of us today have received vaccine shots. We have all used medications. We have all heard of transplant technology. This above example I have used is farfetched. Brain transplants are not an everyday occurrence. They are not yet, at least. However, kidney and heart transplants are beginning to become a more and more common every day. Who knows what is possible with the proper research. Today there are a great deal of people who oppose animal testing in laboratory research. This is limiting our medical capabilities . Could we be holding ourselves back from medical breakthroughs such as a cure for cancer or AIDS? Animal testing is already controlled to a great extent. Many cats and dogs are killed annually by shelters and pounds. Animal testing is not as cruel as it is portrayed and is an essential to reaching medical breakthroughs. Special controls on laboratory animals have been in place since 1876. These have been revised in 1986. These laws are now more commonly known as the revised Animals Act of 1986. This law allows for scientist to perform testing while also safe guarding the animals. Prior to any testing a cost benefit analysis must be applied. In this analysis they review the potential research benefits with the potential for animal suffering. All registered facilities are also required to establish an Animal Care and Use Committee (IACUC) that reviews and approves procedures involving animals before they take place. This organization also inspects facilities semiannually for compliance with the AWA. At least one member of the committee must be a veterinarian. At least one member must be a "public" member, not affiliated with the institution, who represents the general community interest in the care and treatment of the animals. Research facilities must undergo many regulation to ensure animal safety. These regulations are being met on a monthly basis. (#2) There are approximately 56-100 million cats and 54 million dogs in the United States. It is estimated that 2,000 cats and 3,500 dogs are born every hour. There are an estimated 15 million dogs and cats that are put to death in pounds and shelters each year. These cats and dogs are put to their death for the lone reason that the pounds and shelters are overcrowded. Approximately 17-22 million animals are used in research laboratory's each year. That is just about 5 million more animals put to death in labs than are put to death in

Nuestra Senora de Guadalupe

Icon of Nuestra Senora de Guadalupe is also known as Our Lady of Guadalupe or the Virgin of Guadalupe. It is a most famous and most popular Roman Catholic image of a Virgin Mary in Mexico. The legend says that Virgin appeared to Juan Diego Cuauhtlatoatzin, an Indian convert, in 1531 and the witness of that miracle required commemorating it by erection of a church, known as a Basilica of Our Lady of Guadalupe.  There were two apparitions of the Virgin Mary and after the second an icon was painted which is, actually, now one of the most famous in Mexico.This event was historically significant as following it a great number of Indians of Mexico converted into Christianity. According to the information provided in encyclopedia Britannica â€Å"in 1754 a papal bull made the Virgin of Guadalupe the patroness and protector of New Spain, and in 1810 she became the symbol of the Mexican independence movement when the patriot-priest Miguel Hidalgo y Costilla raised her picture to his banner .† (Encyclopedia Britannica)The story of Virgin’s apparition is derived from the Nican mopohua which is thought to be the original source of that event.   Nican mopohua, written in the indigenous Nahuatl language gives an account of the encounter between Virgin Maria and Juan Diego Cuauhtlatoatzin in 1531 on Tepeyac. It says that a widowed convert Juan Diego was traveling to â€Å"attend to divine things† the woman in a bright shine appeared in front of him and said that she was a mother of God and asked Diego to tell the Bishop about her request to build a temple on this hill. She promised to come to those people who, would pray in this temple, and help them.The Nican mopohua is not the only work related to the apparition but it is considered to be the most explicit and most trusted. There is another work relating this story, but this time it is the first Spanish-language apparition account written by Miguel Sanchez. It is this document that for the first time refers to Our Lady of Guadalupe as to a symbol of Mexico. He mentions it in the context that â€Å"this New World has been won and conquered by the hand of the Virgin Mary†¦[who had] prepared, disposed, and contrived her exquisite likeness in this her Mexican land, which was conquered for such a glorious purpose, won that there should appear so Mexican an image† (Brading 2001).When in 1810 Miguel Hidalgo y Costilla and his army fought for the independence of Mexico they used the image of Nuestra Senora de Guadalupe as a sign on their clothes and also as an insignia of their campaign. After Hidalgo’s death a mestizo priest led the army during revolution. He also relied on the holy image and as Krauze in his book states he was confirmed that â€Å"New Spain puts less faith in its own efforts than in the power of God and the intercession of its Blessed Mother, who appeared within the precincts of Tepeyac as the miraculous image of Guadalupe that had come to comfort us, defend us, visibly be our protection† (Krauze, 1997).The Mexican calendar even contains the holiday to honor the Virgin, that is December 12, inscribed by the priest-revolutionary. (Matovina, 2001) Thus during the independence struggle people treated Nuestra Senora de Guadalupe as the symbol and patroness of patriots. They offered up numerous prayers at moments of difficulties and used her image on their ensigns. In this way, Brading observes, political exaltation intervened with religious faith â€Å"to produce a vehement fervor in favor of the sacred cause of liberty. The veneration for this image in Mexico far exceeds the greatest reverence that the shrewdest prophet might inspire† (Brading, 2001). In this way the icon of Nuestra Senora de Guadalupe became not only the sacred symbol of Mexico but also it acquired a profound political implication, the embodiment of the struggle for the independence, so desired by the Mexican people.Though there are still a lot of disputes as regards the verity of the legend about Our Lady of Guadalupe’s apparition its authority still remains very strong in Mexico. In addition to the reputation of the image which inspired people to fight for independence the Virgin is also the symbol of Catholicism in Mexico. As it was stated before the temple was build on the place were Saint Mary was met by Juan Diego, and it was the starting point of active conversion of indigenous people, Aztecs, to Christianity. Nuestra Senora de Guadalupe is still a sound support to the Catholics in Mexico and in other parts of Latin America.Starting from 1737 Nuestra Senora de Guadalupe was recognized to be a saint protectress of Mexico City and then almost two centuries later her protection spread all over the South America. Nowadays, hundreds of people pilgrimage to the church of Our Lady of Guadalupe located on the Cerro of Tepeyac. There are even cases when people do not just walk but crawl on their knees to the church to p ray to Nuestra Senora de Guadalupe, as it is believed that in this way they can merit the cure for their sickness or gain help in the hardship. The image of Our Lady of Guadalupe said to have been miraculously imprinted upon Juan Diego's cloak is displayed there.The woman depicted in this image dresses and looks like an Aztec maiden of the early 16th century. She has brown skin; Meso-American features, and is clothed in a turquoise tunic and a rose colored robe. In short, Our Lady of Guadalupe looks like the Aztecs and not like their European oppressors. The iconic resemblance between themselves and the woman depicted in that image was frequently noted by the contemporary Mexican pilgrims. Many Mexicans love their protectress and often call her with diminutive Virgencita. Pilgrims visit the basilica not only because of where it is, but also because of what it has. The Mexicans often feel admired that she is just like them dark-skinned with black hair and brown eyes.The image of Our Lady of Guadalupe is much more than a mere depiction of the woman Juan Diego claimed to have seen in his visions. It is also a complex collection of floral symbols, astronomical imagery, and other signs that are distinctively Aztec (Barber, 1997; Castillo, 1995). These symbols reinforce the indexical and iconic connections between Our Lady of Guadalupe and the non-Christian religious traditions of the Aztecs. The floral designs that adorn Our Lady of Guadalupe's tunic are symbolic as well as decorative (Barber, 1997).In accordance with the conventions of Aztec glyphs (standardized pictographic designs used by the Aztecs to convey symbolic meanings) the flowers are rendered with a flatness that allows viewers to see them in full. One of the flowers included in the image, the quincunx, appears only once. It is positioned over the Virgin's womb. According to Barber, this flower represented: the four compass directions of the world, with heaven and the underworld vertically encountering earth in the canter, in the â€Å"navel† of the world, or, to use the metaphor, in the navel of the moon, as they call the Valley of Mexico. (p. 72)The placement of this flower over the woman's womb signifies that she bears an important child. That the Virgin is pregnant is also indicated by the black sash she wears around her waste, an Aztec symbol of pregnancy (Castillo, 1995). Located just below the sash is another floral symbol, the nagvioli. According to Castillo, this flower â€Å"represented Huitzilopochtli, the great ferocious sun god of the Aztecs† (p. xix). Our Lady of Guadalupe is thus symbolically linked to Coatlicue, an aspect of the goddess Tonantzin, who was the mother of Huitzilopochtli. This link acknowledges her connection with the goddess she is supposed to have replaced.Also included among the image's floral imagery are nine large, triangular, heart-shaped flowers–the Mexican magnolia–which were traditionally used to represent the nin e levels of the Aztec underworld. In Nahuatl, the language of the Aztecs, the name for these flowers is yolloxochitl. As explained by Barber, â€Å"Yollotl, is `heart' in Nahuatl, and xochitl, `flower'† (p. 76). According to Barber, â€Å"Yolloxochitl was an Aztec metaphor for the palpitating heart torn from the body of sacrificial victims† (p.76).Human sacrifice played a prominent role in the pre-Christian Aztec religion. Barber goes on to state that yolloxochitl can also be â€Å"read as another glyph, too: tepetl, hill, and precisely, Tepeyac Hill† (p. 76), the hill upon which Our Lady of Guadalupe appeared to Juan Diego and the location of the shrine of Tonantzin that had been appropriated by the Spanish missionaries. This flower, then, ties the Virgin to Tepeyac, the hill's previous pre-Christian tenant, and to ritual practices valued by the Aztecs. Some of the flowers that adorn the tunic of Our Lady of Guadalupe are connected with the Aztecs' rich astrono mical symbolism.According to Barber the eight-petaled flowers: can be identified with a Nahuatl glyph for Venus, the Morning and Evening Star. Venus as Morning Star was associated with their god and culture-hero, Quetzalcoatl, who after his self-immolation was taken up into heaven as the  morning star. (p. 73) The image's astronomical symbolism is not limited to flowers that adorn the Virgin's tunic. There are also solar, lunar, and stellar symbols. The most significant of these is the crescent moon upon which the Virgin is situated. To the Aztecs, this symbol represented the Valley of Mexico, their geographical, cultural, and spiritual center.Once it officially affirmed Our Lady of Guadalupe, the Church embraced her with a great show of public enthusiasm. Over the years, the Church has assigned to her such honorific titles as Patroness of Latin America and Empress of All the Americas.Works Cited ListBarber, J. â€Å"The sacred image is a divine codex.† In A handbook on Gua dalupe (pp. 68-73).

Fahrenheit 451: Journal #3 Quote Analysis Essay

In the quote above, Faber describes books and their content to Montag, who as started to rebel against society through books. Faber was a very special and memorable person Montag met in a park a few years back. They had a conversation in which Faber recited some poems to him and because of that, Montag knew he was a rebel; a reader. He was the only person Montag could think of that would help him in his situation. Faber is the one that uttered this quote and is, by far, my favorite character in the book. The way he describes books is so unique. He uses many figures of speech to explain books and even society. Because of this, what he says usually has indirect meanings. Take this quote for example. This quote contains metaphors and personifications that describe Montag’s society and why books are burned. â€Å"Pores in the face of life† is a personification that represents the â€Å"problems in life.† Pores on our faces are unwanted, ugly, problematic. Same with the issues in our lives. It makes people unhappy, and brings torture in their lives. People are afraid of this; therefore, they are removed, avoided. Books reveal these â€Å"pores in the face of life,† so they are removed as well. That’s how Montag’s government controls Montag’s society. Through fake, hollow happiness. The government digs a hole and buries the locked treasure box filled with everyone’s emotions (excluding happiness) and issues deep inside the hole. Heck, they even teach society to do that themselves! For the next sentence, â€Å"flowers† is a metaphor for ideas. â€Å"Good rain† and â€Å"black loam† represents creativity and imagination. â€Å"Flowers† need Good rain† and â€Å"black loam† to blossom into something grand, special, unique. But, because the â€Å"flowers† are growing on other â€Å"flowers,† they become identical to it. Each and every â€Å"flower† grows on each other until the world is covered in identical flowers. A few are different, yes, but they slowly dwindle through the influence of the identical â€Å"flowers† and the disturbance of nature those â€Å"flowers† created. Those â€Å"special flowers† may transform into an â€Å"identical flower,† or, they die. Journal #4 May 5, 2013 â€Å"†¦They were gone. The Hound was gone. Now there was only the river and Montag floating in a sudden peacefulness, away from the city and the lights and the chase, away from everything.† (Pg. 140, Fahrenheit 451) This quote occurs after Montag kills Beatty and two other firemen, as well as burn the Salamander, after his house was burnt by them. Because of that, he is now being chased by firemen in helicopters and Salamanders, and a more efficient and high tech Mechanical Hound. Montag visits Faber one last time, receiving money, new clothes, and directions from him, and then runs into the river, which carries him away to safety. The Hound and firemen then loses track of him. This quote is where, in my opinion, the climax ends and the resolution starts. It’s when Montag completes his transition from â€Å"mindless follower† to â€Å"independent thinker.† All with nature’s aid. Nature, at this moment, is shown as something that overrules technology. Even when it’s faced with the highest, most efficient technology that the humans can create, nature wins. Nature was able to bring Montag to safety from the Hound and the clutches of society and technology, to help him escape from everything that was holding him back. The peace and relaxation nature provides help Montag complete his thinking process, which was incomplete because he couldn’t really think when he was surrounded by the fast-moving, overly colorful things, people that didn’t give a damn about anything except for themselves and their happiness, and a government that’s watching your every move. Not until he was completely separated from all that was he able to accept his new self and to move on; to make peace with his inner conflicts. Even he wasn’t able to accept and make peace when he was with Faber, someone he trusted and cared for. He was wounded by technology and healed by nature.

My Favorite Holiday My favorite holiday is Christmas. Christmas was the month Jesus Christ was born. Traditionally celebrated at home, Christmas is thought to be a family holiday. However nowadays the habits and ideas of people have changed very much. Christmas becomes more of a global holiday when it is appropriate to meet with many friends and go out for a round the night crazy celebrations. Every person finds their own most favorite thing about Christmas. In this small essay I will explain what this holiday means to me, and what are the best parts of it that I enjoy. As for me, the best thing about Christmas is giving. During Christmas I buy toys and clothes and to donate them to Churches and Charities to help those that are less fortunate. Christmas season people are usually more friendly and gentle to each other. They try to leave every sorrow and offense behind in the year that is passing by. I think this approach is a exercise for a person to make them feel good mentally and physically giving happiness and hope for a better future in the next year . When there is joy in the air, the organism wants to celebrate along with the mind. The renewal of the hope is felt all around. I have loved the celebration of Christmas since my early childhood. I still enjoy decorating the Christmas tree and simply walking around the streets looking at the decorations of the buildings and the trees around the city. In our country Christmas trees stand everywhere, for instance you can see them in squares and parks, in schools and offices, in shops and at homes. And what fun is it to wake up early in the morning and take a look under the tree seeking the presents Santa Clause brought. Of course, now that I am grown I know that someone from my family puts the presents there but I still wish to think that a very kind and fair old man called Santa Clause does it. As Santa brings the presents to the small children, the grown-ups enjoy exchanging presents with each other. I like giving presents to people, also like to get them as well he-he!! Most of all in conclusion WHAT IS CHRISTMAS? Christmas is the season during which Christians everywhere give thanks to God the Father for the birth of His Son, Jesus Christ.
