Predicting School Violence essays

Predicting School Violence essays Are There Tests That Could Predict Violence in School Students? This is an overview of the types of constructs which one might look at to determine if a student is in a high risk category for acting out in a violent manner, and the types of tests which would measure those constructs. We will look at some of these predictors, the constructs they attempt to measure, and how this might aid in predicting future behavior. There have been a lot of studies, interventions, programs, and models designed to reduce or predict violence among our youth. The strongest predictor being past violent behavior. Most of these studies have been linked to some type of deficiencies in the home environment and school environment. The overwhelming question facing America now is - Why would a student who has almost anything he desires, living in an upper middle class neighborhood, bring a gun to school with the purpose of killing his classmates and teachers? The question for researchers is - Can we predict which students are likely to engage in this type of behavior? The resounding answer so far seems to be negative. There is not any test, inventory, or self-report scale which can tell us which students will act out in this manner. However, reviewing the literature there appears to be different types of measurement when looked at aggregately, might identify those students who would be at higher risk although they do not show a past history of violence and therefore fall outside of the previously researched areas. Some of the things we would hope to assess in identifying violence-related attitudes, beliefs, and behaviors among youths would be broken into three categories: - aggression, couple violence, education and school, employment, gangs, gender roles, television, handguns 2. Psychological and Cognitive Assessments - aggressive fantasies, role models, attributional bias, depression, psychological distress, fatalism, future aspirations...

Examples of Balanced Chemical Equations

Examples of Balanced Chemical Equations Writing balanced chemical equations is essential for chemistry class. Here are examples of balanced equations you can review or use for homework. Note that if you have 1 of something, it does not get a coefficient or subscript. The word equations for a few of these reactions have been provided, though most likely youll be asked to provide only the standard chemical equations. 6 CO2 6 H2O → C6H12O6 6 O2 (balanced equation for photosynthesis)6 carbon dioxide 6 water yields 1Â  glucose 6 oxygen 2 AgI Na2S → Ag2S 2 NaI2 silver iodide 1 sodium sulfide yields 1 silver sulfide 2 sodium iodide Ba3N2 6 H2O → 3 Ba(OH)2 2 NH3 3 CaCl2 2 Na3PO4 → Ca3(PO4)2 6 NaCl 4 FeS 7 O2 → 2 Fe2O3 4 SO2 PCl5 4 H2O → H3PO4 5 HCl 2 As 6 NaOH → 2 Na3AsO3 3 H2 3 Hg(OH)2 2 H3PO4 → Hg3(PO4)2 6 H2O 12 HClO4 P4O10 → 4 H3PO4 6 Cl2O7 8 CO 17 H2 → C8H18 8 H2O 10 KClO3 3 P4 → 3 P4O10 10 KCl SnO2 2 H2 → Sn 2 H2O 3 KOH H3PO4 → K3PO4 3 H2O 2 KNO3 H2CO3 → K2CO3 2 HNO3 Na3PO4 3 HCl → 3 NaCl H3PO4 TiCl4 2 H2O → TiO2 4 HCl C2H6O 3 O2 → 2 CO2 3 H2O 2 Fe 6 HC2H3O2 → 2 Fe(C2H3O2)3 3 H2 4 NH3 5 O2 → 4 NO 6 H2O B2Br6 6 HNO3 → 2 B(NO3)3 6 HBr 4 NH4OH KAl(SO4)2Â ·12H2O → Al(OH)3 2 (NH4)2SO4 KOH 12 H2O Check Equations To Make Sure They Are Balanced When you balance a chemical equation, its always a good idea to check the final equation to make sure it works out. Perform the following check:Add up the numbers of each type of atom. The total number of atoms in a balanced equation will be the same on both sides of the equation. The Law of Conservation of Mass states the mass is the same before and after a chemical reaction.Make sure you accounted for all types of atoms. Elements present on one side of the equation need to be present on the other side of the equation.Make sure you cant factor out the coefficients. For example, if you could divide all of the coefficients on both sides of the equation by 2, then you may have a balanced equation, but not the simplest balanced equation. Sources James E.

Educational Trends Education - Research Paper Example In such an immersive computing environment, where notebooks and pens are replaced with smart phones, iPods and laptops this era of pervasive education technology, is marked with revolutionary educational trends. The development and rising popularity of social networking and micro-blogging sites has upped the ante, making access to information just a click away. Such trends within the domains of primary and secondary education, has significant implications on the manner in which such education is imparted across the globe (Leu, 2001; Gilster, 1997). This paper, on â€Å"Educational tends† aims to discuss both the current as well as future trends in education, and the use of ICT (Information and Communication Technology) within classrooms and its likely impact in shaping, nurturing and developing the knowledge and cognitive learning abilities of students over the years. Historical Background: ICT in Classrooms The twentieth century was swept away by technological makeover, and c omputers entered the classrooms as educators realized its power and impact as an effective teaching aid (Dwyer et al., 1991). However, during this era, computers were merely used as a data management tool for tracking grades, attendance and reviewing test results. Moreover the ratio of computers per student was low. During the mid 20th century, this highly rigid approach towards computer usage changed significantly from predominantly conventional behavioral attitudes to a more constructivist approach (Anderson, Speck, 2001). Current trends: Overview The 21st century classrooms have had a drastic makeover from that compared to the 20th century classroom, in the sense that it has now become more interactive as opposed to passive learning, and includes the addition of various gadgets which are incorporated on a large scale across various schools. The technological tools in used in the past were mostly passive in nature which involved little or no interaction from the students, and were limited to just listening, watching, or at the most, taking notes. However, the tools used today include greater participation from the students via the use of interactive media where they are encouraged to make presentations and communicate and share their experiences via blogs and vlogs (Smolin, Lawless, 2003). Figure 1: Instructional technologies timeline from the year 1900 - 2004 Source: Whelan (2005) Pp.14 The use of interactive whiteboards has drastically increased and remains one of the most popular tools of teaching across American classrooms. Furthermore gadgets such as PDAs and hand-helds are also being used primarily for middle school and high-school students. Also, there are various online resources which offer interactive learning to students by way of games, puzzles and quizzes which help them in understanding key concepts in a fun entertaining and engaging way. Future trends: The conventional definitions of schools as buildings made of bricks and walls are likely to change to 'nerve centers' virtual space occupied by e-teachers and e-learners, connected by technology. The role of teachers in such a space is likely to expand from merely the providers of education to that of information and knowledge generators. Until recently, students were accustomed to access education through schools, but the

Hebrew Bible and Christian First Testament Essay

Hebrew Bible and Christian First Testament - Essay Example The early part of the history of Israel is technically Biblical history. On this note, it is vital to point out that the history of Israel, rather than using a theological reading only, ought to be governed by religious perspective. This is particularly so as it makes relevant connections with the past and present, though at different timelines. A brief outline of the history of Israel starts with the call of Abraham when he went to the land of Canaan. From Abraham through Isaac and Jacob, the history of Israel as a nation begins to take shape. The jealousy of Joseph’s brothers changes fortune and Israel takes his sons to Egypt to escape the seven years of famine. Migration and conquest of Canaan start with Moses and ends with Joshua. Briefly, a number of judges rule Israel, amongst them Deborah, Samson, and Gideon until the birth of Samuel when Israel later demands an earthly King. Historically, this period takes place somewhere around the 1300 B.C and covers the reign of Dav id Solomon and the division of Israel. The division of Israel into Southern and Northern Kingdoms follows closely with the fall of Israel and the exile into Babylon. The history of Kingship in Israel is widely covered in first and second Kings. This critical period marks Israel’s fall away from God and subsequent punishments by being exiled. The prophecy of Daniel actually takes place in exile.Around 539 B.C., Babylon falls and prophets Ezra and Nehemiah led the first phase of return into the Promised Land....

The history of Kingship in Israel is widely covered in first and second Kings. This critical period marks Israel’s fall away from God and subsequent punishments by being exiled. The prophecy of Daniel actually takes place in exile (Scott, 2000, p. 357). Around 539 B.C., Babylon falls and prophets Ezra and Nehemiah lead the first phase of return into the Promised Land. The history of Israel during this time majorly dwells on liberation prophesies and various small revolts that are not covered in the Bible. During this time, Christianity has not been born but there are prophecies by Major Prophets such as Isaiah, Jeremiah and Ezekiel, pointing to a salvation of humankind through a God chosen Messiah. God restores the Israelites back to their land in readiness for the birth of Jesus Christ the Messiah. This is what Scott (2000, p. 307) refers to as the Messianic hope. This happened during the Roman reign at when Caesar Augustus was at the helm of Roman leadership. Other events happen in the context of the New Testament although they still form part of the history of Israel. A critical

History of Fast Food Essay Example for Free

History of Fast Food Essay Fast food has been a growing phenomenon for since its introduction in 20th century. The changes in American culture pushed the fast food industry into a staggering growth arena and have changed the way consumers purchase and eat forever. The fast-food industry that now extends throughout the world has its roots in the United States. Fast-food restaurants are often regarded as emblematic of a new global culture, but the industry has indisputably been shaped by its American origins. (Leidner 8). Fast Food has developed from being a convenience to a necessity, widened the financial gap and became an international phenomenon. The first drive-in restaurant, Royce Haileys Pig Stand in Dallas, Texas, was opened in 1921, and offered pulled pork BBQ and introduced Texas Toast. As one southern fan of Royce Hailey’s pig stand put it: â€Å"Folks went hog wild when the first Pig Stand opened in Dallas in 1921. Agile car hops leaped onto running boards of Model-Ts to deliver curb service to a generation on the go. It was the age of the automobile, and Pig Stands multiplied across America faster than you can say soooo-eeee. It took the Great Depression of the 30s to slow The Pig down. †(Sowa). Drive-in services were not very popular at this time because automobiles were expensive and few and far between during the Great Depression. Then nearly three decades later the drive-in restaurant enjoyed a degree of success during the 1950’s. Drive-ins celebrated the cultural importance of the automobile and Drive-in restaurants proved (to be the) most popular, places where carhops served customers directly in their parked automobiles (Young, and Young 29). This convenience which enabled people to order their food and eat it in the open air without having to unbuckle their seatbelts changed American fast food forever (Woloson). Car hops, as they were also called, became familiar congregation centers for teenagers as well† (Woloson). The rise of the fast food restaurant would not have been possible without constant changes in American culture. The 1950’s brought about American lifestyle changes. With the end of the war Americans had saved money and moved to the suburbs. For the first time in history middle class married women with women with children were entering the work force. â€Å"Married women comprised the majority of the growth in the female work force throughout the 1950s, and between 1940 and 1960 there was a 400 percent increase in the number of working mothers; by 1960, women with children under the age of eighteen accounted for nearly one-third of all women workers†(Coontz 161). The working women and the decrease of free time may be a direct contributor to the growth of the fast food industry. The development of an affordable automobile and the simultaneous governmental support of new road systems physically reinforced this cultural melding, enabling car owners, especially, to go to places they had never been before. There was a boom in the tourist industry in the 1950’s and 1960’s. The key to the expansion of tourism demand was the rise in disposable incomes in the 1950s and 1960s. (Beauregard 225). Travelers, who once went by rail, boat, or horse, were now moving faster by car. Consumers began to value things such as speed and convenience as part of their trips. Fast food restaurants began making their food faster and faster and Americans love the convenience of letting someone else do the cooking, especially when they are vacationing (Bijlefeld, and Zoumbaris 51). As travelers not only did they need affordable and reliable places to stay they needed quick, convenient, and inexpensive eateries. The need for fast, reliable, affordable, and convenient food, along with an increasing acceptance among Americans of more fast pace culture, led to the rise of the fast food industry. Fast food restaurants sprang up in both urban areas and along the nations highways in record numbers after the introduction of the fast food phenomenon known as McDonalds. â€Å"The first fast food restaurant (was) opened by the two McDonald brothers in 1937 in Pasadena, California. Their established restaurant had experienced high demand at specific times (for example, workers’ lunchtimes) and they responded with a circumscribed menu (burgers) and were able to serve large numbers at high speed and low price. The assembly line procedures, with food preparation and serving made into simple repetitive tasks, combined with a specialized division of labor for each stage, have been recognized as constituting the first ‘fast food factory’† (Beardsworth, and Keil 120). This enabled people to get their food faster and set the standards for the future of the fast food industry. As the McDonalds chain grew and other chains started to sprout up people began to accept the new culture of food service. The working-class food held largely in disrepute. The gaining widespread popularity of fast food made it a staple food in diets of many Americans diets. The most successful of these stands quickly multiplied, taking advantage of the growing popularity of this new fast food and applied industrial principles of standardization to its development. McDonald’s is considered the first fast food restaurant and recognized the potential of this relatively fast and simple food. The organization of McDonalds created standardized methods in its production. The history of White castle dates back to the 1920’s is seen as the first and most influential restaurant chain (â€Å"White Castle†). â€Å"White Castle is credited for beginning the franchise system that inspired many â€Å"(Woloson). White Castle set standards, began standardization of the cooking line, and created the first restaurant which duplicated the original. In retrospect it can be said that White Castle was the start and set high standards for all the other franchise restaurants in the United States. The hamburger fulfilled economic as well as cultural needs for inexpensive food. Although there was not a food shortage during the great depression food was expensive and affordable food options like the local hamburger stand was a blessing. By the end of 1930, White Castle had sold over 21 million hamburgers and then by the end of 1937, this number had increased to over 40 million (Woloson). Fast food began to make a steady incline towards the end of World War II. â€Å"Franchises were not unique to the 1950s; they had been around since the early decades of the twentieth century, patronized by a public increasingly used to and insistent upon the supposed reliability and trustworthiness of branded goods†(Woloson). White Castle, A W Root beer, and Howard Johnsons, were some of the first and most successful restaurant franchises. Although it took the ideals of postwar culture to wholly support the fast-food franchise it laid the foundations for the companies to make billions of dollars. In 1955 Ray A. Kroc, a Chicago Milkshake salesman, discovered the McDonald’s restaurant in California and saw a goldmine. He partnered with the McDonald’s brothers, opening 228 franchises by 1960. Kroc happily bought out the McDonalds’ shares of the company in 1961. Kroc, an incredible entrepreneur, wanted to make the customers to identify with the restaurant and make it seem homey. â€Å"By 1988, McDonald’s had opened its ten thousandth restaurant and today there are over 30,000 McDonald’s restaurants worldwide† (â€Å"History of Franchising†). â€Å"Krocs success lay in his approach not specifically to cooking individual food items, but in conceiving of his franchise operation in its entirety† (Woloson). The methods and success of McDonald’s Franchises have set a tone for the fast food industry. Although â€Å"White Castle was the first restaurant that encouraged carry-out for those customers on the go the restraint developed standard floor plans and architectural designs that could be easily duplicated† and set these standards for others in the industry (Woloson). McDonalds uniform restaurants, kitchens, dining rooms, and methods of standardized cooking techniques set this great restaurant apart and distinguish it from the other fast food restaurants. Ray Kroc had some competition with the introduction of popular fast food restaurants such as Taco Bell, Wendy’s, and Burger King. One may say ethnic food could be considered a genre for the fast food franchise system, Taco Bell originated in 1962 and was the first ethnic franchise restaurant, paving the way for many more. â€Å"Wendys, specializing in bigger, better, and more expensive hamburgers and introduced the first drive-thru windows at their restaurants, which were so popular that Burger King and McDonalds had to follow suit†(Woloson). As an industry fast food will continue to grow, change, and adapt to the needs of the culture around it. Expanding to international markets the fast food industry offers cultural acceptable products. â€Å"Multinational fast-food chains have now become household names, and in terms of sales and units tend to dominate national markets. Indeed, the industry is becoming more internationalized with brands like Burger King being bought by the British multinational Diageo; and McDonalds has recently bought a stake in Pret a Manger. However, some of the largest brands in this sector are still American-owned, such as McDonalds, KFC, Pizza Hut, and Wimpy†(Royle and Towers 3). One great concept is international fast food chains often support the local economy, buying local products, but sticking to the same well known recipes to get desired results. The fast food franchise of the 20th century has set and defined a world-renowned concept of the way people order, eat, and enjoy the food that they purchase. The fast food industry is one of enormous power and economic strength. Fast food restaurants represent Americas cultures and, in many ways, how other cultures strive to be like America.

Nursing Students Need Better Clinical Experiences Essay -- nursing stu

Hospital, only one word but somehow is thought of in a bad connotation. No one wants to be in the hospital and no one has a great time, however there are people who can make your stay better. Nurses can make your stay comfortable and relaxed or painful and scary. Having a caring nurse can make your experience exceptional while having an awful nurse can make everything worse. No one wants the uneducated nurse, and there is something we can do about. Nurses are â€Å"born† at the very first nursing class they attend and grow with each clinical. Clinical is where nursing students can practice as nurses in a specific area under the supervision of a licensed nurse. These clinicals are essential to the development of nursing students and need to be educational. Nursing students at State University need better clinical experiences and better clinical sites. Clinical sites that have nothing to do or preceptors who don’t want to educate should be cut out and replaced with better sites. Ideally each clinical should allow nursing students to gain experience in critical skills and patient ca...

Explain the theory of Virtue Ethics Essay

Aristotle originally introduced virtue Ethics to society in ancient Greek times. Virtue Ethics tells us that we should look at the character of the person instead of the actions or duties a person performs. Instead of concentrating on what is the right thing to do, virtue ethics asks how you can be a better person. Aristotle claims that leading a virtuous life is easy, and those who do, do so to be happy. Happiness is the ultimate goal for everyone in life. To become a better person, you must practice virtuous acts regularly. After a while, these acts will become routine and so the virtuous acts will be nothing more than everyday life and the person a virtuous person. Aristotle said that although virtues should become a habit we must never forget that we behave in such a way because it is right. For example, if a singer practices singing everyday, they will become better at it and used to doing it. This is the same as people who practice their virtues and soon automatically act in the right way, by practicing our skills we improve them, becoming happier. Virtues should not be an effort, but simply a part of everyone’s personality. Aristotle says that virtue is something that we acquire and are not just born with, people are not inherently good or bad, but become good or bad according to the habits they develop. Aristotle said that a virtue was a ‘Golden Mean’ in between to vices. These ‘Vices’ are two extremes of a scale at opposite ends, one of excess and one of deficiency. For example the vices would be shamelessness and shyness, and the virtue modesty. Another example of this would be rudeness and a sense of humour as the two vices and the virtue as wittiness. Such virtues must be cultivated, we must learn when to use certain virtues and to what extent, for example we must not ever use humour in excess to act like a fool, but at the same time we must also not pass into rudeness. Two philosophers, Anscombe and MacIntyre say that there has been a mistake in how virtues have been portrayed. The majority of people look at the actions a person does to judge whether they are virtuous or not. The way in which we behave provides an opportunity for others to judge our virtues and vices. This however is not right. People should look at the character within and look at what the person believes is right and how they think they should help people instead of what they do to help. A famous example of a virtuous person is Mother Theresa. She helped millions of suffering people across the world and for this became well known as a virtuous person. There are hundreds of other virtuous people who would have liked to have helped but were unable to do so in such a huge way who are not considered as virtuous, but these people are just as virtuous but not recognised for it. Aristotle tells us that we are most likely to learn virtuous behaviour from watching others. If we experience others being kind to us and see the happiness it creates we are more likely to practice it then if we were just told to do it. For example, if we were told to be courageous we may occasionally stand up for small things that we disagree with, but if we see someone telling others off for not doing the right thing then we are more likely to not allow bad behaviour towards ourselves. Aristotle said that the best way of becoming virtuous was to follow in the footsteps of a virtuous person, e.g. Mother Theresa and do what they do. Virtue Ethics is relative; Aristotle recognised that virtues in one country may not be the same as virtues in another. He believed that there was no absolute platonic good beyond our world. As virtues have evolved through habits of society it is probable that different societies would deem different actions good or bad. However there is no difference between the virtues of a community and individuals within that community, the supreme happiness that Aristotle talks about is one for the community, and not just and individual. MacIntyre suggests that philosophy is too far removed from ordinary life and said that it is not good enough that philosophers spend their time debating the nature of ethical language or forming reasoned theories of morality in a way that is far removed from real people and real life. All actions are done in order to reach an aim. A successive series of actions are also for an aim, for example getting up in to morning to go to work, is to make money, is to feed our families is to go on nice holidays is to but them nice things etc. all ultimate aims is to make people happy, everything is subordinate to the supreme good, which is happiness. Everyone has different ideas of what happiness is and different things all make different people happy, and Aristotle called this feeling of all round well being eudemonia. Therefore, Virtue Ethics concentrates on what a person is then what a person does. Its aim is to achieve something, which people genuinely want rather then being based on arguably incoherent ideas about the after-life. It is a system, which can be easily applied and understood by all. It fits into a variety of philosophies, and religions, which both do and don’t include God. However, there are a few problems with Virtue Ethics. Ones of these which has been pointed out by MacIntyre is that although a virtue is the ‘golden mean’ between two vices it cannot be applied to all virtues. Virtues such as promise keeping, loyalty, and compassion do not fall between any two vices and so Aristotle’s theory of this does not really work. Another problem with this theory is that it is of little help to people faced with a moral dilemma. It does not help them make a decision like other theories such a natural law or utilitarianism.
