Juvenile Smoking and Marijuana Use - 1622 Words

Juvenile Smoking leading to use Marijuana (Research Methods for Criminal Justice) Name: Institution: Abstract Research has found that teenagers who used cigarettes were twelve times more likely to graduate to marijuana use. A similar study conducted by Denise Kandel (1992) revealed that use of marijuana affects dopamine levels in the brain in a similar way to nicotine. Cigarette smoking facilitates consumption of other substances. Smoking cigarettes initiate juveniles into the sensation of drug inhalation, which desensitizes them from the feeling of smoke clouding their lungs. This paper finds that marijuana pervades the life of a juvenile tobacco smoker. Teenagers who smoke cigarettes†¦show more content†¦However, this is not directly associated to the smoking of cigarettes as juveniles. When an individual takes on the road to drugs, the turning point in life to unhook oneself from the addiction comes late. When one gets addicted to cigarettes, followed by marijuana, the next drug on the list is usually Heroine of cocaine. Drug taking is like a ground down an escalator. Once on the escalator, it is hard for one to get off on the way. A reduction of fifty percent in smoking of cigarettes among juveniles could cause a reduction in use of marijuana among juveniles by as much as 16.5-28.5% (Ochsner, 2006). The high end of this range makes the assumption that half of the fifty seven percent of juveniles who used cigarettes would not have used marijuana if they had not experimented with cigarettes. The low end makes the assumption that forty two percent of the fifty seven percent of juveniles who first smoked cigarettes might try marijuana even without trying cigarettes first. Sampling and Research Design This research used surveys, and the combination of the statistics obtained with those obtained from other research carried out prior to the research. The survey involved filling out of questionnaires distributed to several juvenile volunteers. The survey was an open one, where anybody who had juvenile experience could help in the survey.

New Business Model for Snapchat- myassignmenthelp.com

Question: Discuss about theNew Business Model for Snapchat. Answer: Introduction Snapchat is an American technology and social media company founded on September 2011 by Evan Spigel and Bobby Murphy in Venice. The company currently has 4 in house products namely: Snapchat, Spectacles, and Bitmoji Zenly. The company has been in discussion since its inception. The company was initially founded as a camera company, due to its gaining popularity; it earned its reputation as a social media company, giving companies like instagram, Facebook and watsapp a run for its money. Mark Zuckerberg, Founder CEO of Facebook wanted to acquire Snapchat, but the owners were aware of its popularity and thus declined the offer at a very nascent stage. Since then, the company has been just gaining uncontested popularity, forcing many social media giants to follow footsteps of snapchat.[1] From Capital to Value design: Snapchat was funded by Bridge funding and light speed ventures as seed funding, post that the company raised some $ 13.5 MN in Series a funding round which made the valuation of the company to $ 70 MN. By 2016 the company has completed 4 rounds of funding at was sitting at a figure of $ 1.2 Billion. Facebook at that time offered Snapchat $ 3 Billion, it was a good amount, considering the valuation, but the owners denied it and now they are sitting at a valuation of $ 22 Billion. The company never showed the signs of defeat or giving up to the pressures of Silicon Valley and are going strong with 173 Million daily active users. The owners believed in the business model and its target audience, they knew with the positioning, they are sure to succeed, and money will come eventually, this led them to work on value designing and move forward from capital.[2] From Value chain to network: Snapchat describes itself as a fun messaging app which is target to the youth, the chosen demographics is for the age bracket of 16 to 40, and the company has penetrated the market excessively well, with youth using Snap as a daily jargon among friends. Snap me, add me on Snap are some of the common phrases the youth is using, Snap streak, snap filters are some of the most popular features which the audience is connected to, hence building a network amongst its users. Collaborating different features in one single product, packaging and giving the solution to the audience is the differentiating factor for snapchat.[3] From Having to Being: Snapchat has changed the entire landscape of social media, by introducing its revolutionizing features. The predominant idea behind snapchat was to maintain the privacy, a user once views a picture or a video, and it gets automatically deleted and is not stored even in the cloud. This idea stuck with the youth and thus people started using Snapchat. Later the company kept on innovating new product and features to engage the audience. Brands, seeing the youth moving onto Snapachat, diverted their branding strategy towards Snapchat, and now its like mayhem, every brand is advertising on Snapchat. Thus the company gradually moved from just having to being the leader in innovation. Instagram, Facebook and watsapp are taking inspiration from Snapchat these days and are copying its product to keep up with the growth trajectory of snapchat.[4]

Those Winter Sundays Robert Hayden Essay Example For Students

Those Winter Sundays Robert Hayden Essay A sons love for his father is sometimes not acknowledged until he is an adult. Children often become so wrapped up in their own tasks and obligations that they take for granted the simple acts of loving support given to them by their parents. And parents sometimes feel scared that obvious signs of love and emotion will scare off a child, so they just do all they can to make the childs life run smoothly and try to fade into the background when it comes to tender moments. In the poem Those Winter Sundays, Robert Hayden uses figurative language and other literary devices to show a fathers love for his son as well as the sons realization of that love. The cold that Hayden describes in the house is a reoccurring hardship that the father must face in his life. Sundays too my father got up early and put on his clothes in the blue black cold, (lines 1-2, stanza 1). The father woke up early on his treasured time off from work to make sure that the house was warm for his son. We will write a custom essay on Those Winter Sundays Robert Hayden specifically for you for only $16.38 $13.9/page Order now The cold is described as if it were a tangible item causing the reader to be drawn in to the poem. No one ever thanked him. (line 5, stanza 1). This quote illustrates the fact that the father did this not for praise or to make himself look better in the eyes of his son, but because he would rather compromise his own comfort and enjoyment then have his son start the day off in the cold. Hayden uses figurative language to bring alive the cold and to make it seem like more of an enemy for the father. earing the chronic angers of that house, (line 4, stanza 2). The son is speaking of the dreaded cold, which he wishes that he did not have to face just as much as the father. It shows that the father was really making a contribution towards the happiness of the son by making the effort to rid the house of it. and hear the cold splintering, breaking. (line 1, stanza 2). In this line, Hayden uses imagery to represent the fire that the father builds which helps to defeat the cold. The splintering and breaking are the sounds of the logs being burnt and, as the son finds later, the cold dying. Flashback is used to show the true reason behind the fathers acts and the sons subsequent comprehension of his fathers true feelings. driven out the cold and polished my good shoes as well. What did I know, what did I know of loves austere and lonely offices (lines 2-5, stanza 3). The son realizes here that his father did the things that he had always simply thought of as done. He looks back and sees how much his father must have done for him without being acknowledged. Throughout the poem, Hayden uses the imagery and other forms of figurative language as well as flashback techniques and a consistent setting to paint a picture for the reader about the relationship between the father and son. He describes how the father shows his affection for his son and how the son takes that in. At the end of the poem, the son contemplates his fathers motives and finds the true emotion behind the fathers actions.

Race Education comparing short stories essays

Race Education comparing short stories essays The two children portrayed in the short stories The Circuit by Francisco Jimenez and Dobys Gone by Ann Petry are at a disadvantage because of their races when it comes to forming friendships, overcoming obstacles, and preserving their childhood. While these two stories focus on one character, the difficulties that these children endure plague entire communities and groups of people. In the stories, both children are from minority backgrounds. The young boy in The Circuit is a member of a migrant family and is forced to change schools and move often while Sue, the little girl in Dobys Gone, is African American and is ridiculed because of her race. This causes them to feel like outsiders, making it difficult for them to form concrete relationships. Judging from the way her classmates hurl insults such as nigger girl, her legs are black, and how do you comb that kind of hair?(401), it is obvious that it is a struggle for Sue to fit in and form friendships. Sue has a stronger relationship with her imaginary friend Doby than she has with any children in her class. It is not so obvious in The Circuit that the boy doesnt make friends with his peers; however, instead of playing with the other children during lunch he spends time in the classroom of his teacher, his best friend at school,(262). Because he is Hispanic and new at the school it would be a challenge for him to make friends with the other students because his family is constantly packing everything into cardboard boxes(257) and moving again. Unlike this boy though, in Dobys Gone, Sue eventually makes friends with two of her classmates despite racial issues. Part of the reason Sue forms the friendships with the two other children is that she begins to fight back against her tormenters. She lashe ...

How to Get Learning Accommodations at School

How to Get Learning Accommodations at School Some students struggle in school and need more support than is typically found in the traditional classroom, but that extra support isnt always easy to come by. For college students, typically the institution will require that the student provide documentation and request accommodations in a timely manner, and most will have the resources available to meet the students needs. However, the same isnt always true at secondary schools or middle/elementary schools. For schools who dont have robust academic support programs, students may be  forced into special education classrooms or they may be required to stumble along without accommodations in the traditional classroom.   However, there are options for students struggling in school, and one of those options is a private school. Unlike public schools, parochial and private schools do not have to grant students with learning disabilities accommodations. This ruling falls under section 504 of the Rehabilitation Act  and is a direct result of the fact that private schools dont receive public funding. These private schools also have a pass when it comes to the need to follow the regulations of the Individuals with Disabilities Act (IDEA), which states that public schools must grant students with disabilities a free appropriate public education. In addition, unlike public schools, private schools do not offer students with disabilities IEPs, or Individual Educational Plans. Private Schools: Varying Resources and Accommodations Because they do not have to adhere to these federal laws governing the education of students with disabilities, private schools vary in the support they grant to students with learning and other disabilities. While years ago, private schools often said that they did not accept students with learning issues, today, most schools accept students who have diagnosed learning issues, such as dyslexia and ADHD, and other issues such as autistic spectrum disorder,  recognizing that these issues are actually common, even among very bright students. There are even a number of private schools who cater to the needs of students with learning differences. Some private schools for learning differences were founded specifically for students whose learning challenges  dont allow them to enter the mainstream classroom. The goal is often to support students and teach them to understand their issues and develop coping mechanisms that allow them to enter the mainstream classroom, but some students remain in these specialized schools for their entire high school careers.   Dedicated Learning Specialists In addition, many private schools have psychologists and learning specialists on staff who can help students with learning issues organize their work and refine their study skills.  As such, a number of mainstream private schools even offer academic support program, ranging from basic tutoring to more comprehensive academic support curriculums that provide students with a personal educational expert to help them better learn how they learn and understand the challenges they have. While tutoring is common, some schools go beyond that and offer organizational structure, time management skill development, study tips, and even provide advice on working with teachers, classmates and handling workloads.   Private schools also may be able to grant accommodations to help students in school, including the following: extra time on testsuse of a computer or tablet for writing in-class essays and assignmentshelp from a learning specialist to learn how to prepare for tests, study, organize study materialsuse of a private room for testing or work If youre thinking of private school and either know or suspect that your child may need extra assistances, consider these steps you might pursue to determine if the school can meet your childs needs: Get Started with Professional Evaluations If you havent already, make sure to have your child evaluated by a licensed professional. You may be able to have the evaluation conducted by the local school board, or you may ask your private school for the names of private evaluators. The evaluation should document the nature of your childs disabilities and the required or suggested accommodations. Remember, that while private schools arent required to grant accommodations, many offer basic, reasonable accommodations, such as extended time on tests, for students with documented learning issues. Meet with Professionals at the School before you apply Yes, even if youre just applying to the school, you can request meetings with the academic specialists at the school. Assuming you have the testing results available, you may set up appointments. You would likely coordinate these meetings through the admission office, and they can often be combined with a school visit or sometimes even an Open House, if you provide advance notice. This allows both you and the school to assess whether or not your childs needs can be properly met by the school. Meet with Professionals at the School after youre accepted Once youre accepted, you should schedule a time to meet with your childs teachers and learning specialist or psychologist to begin developing a plan for success. You can discuss the results of the evaluation, the proper accommodations for your child and what this means in terms of your childs schedule. Here are more strategies about how to advocate for your child with learning issues. Article edited by Stacy Jagodowski.

Sexuality around the world Essay Example | Topics and Well Written Essays - 500 words

Sexuality around the world - Essay Example As medicine strives to provide medical explanation of homosexuality, sociologists and sexologist aim to understand the psychology of homosexuality in the cultural aspect. While homosexuality is an expression of personal freedom, it also leads to social issues such as harassment, persecution by the society, and violence. One of the most common factors contributing to discrimination against homosexuals is the gender orientation of the society. As cultural traditions vary from country to country, so does the acceptance of homosexuals and bisexuals. In a research by Judith Mackay, about 50 countries consider male homosexuality as illegal; 8 of which (mostly Muslim countries) impose the death penalty (75). This unfavorable attitude toward homosexuality causes sexual dysfunction as homosexuals are hindered in expressing their sexuality. Homosexuals experience sexual dysfunction for fear of being persecuted. In addition, social pressures contribute to the loss of integrity, as well as the economic and social status of homosexuals. While gender orientation causes psychological, sexual dysfunction among homosexuals, women in cultures practicing female genital mutilation experience the same dysfunction in the physical aspect. Female genital mutilation (FGM), as a cultural practice, deprives women to have sexual pleasure for the thought that it prevents them from having sexual relations with men other than their husbands. FGM also causes physical, sexual dysfunction, which is otherwise known as hypoactive sexual disorder. Hypoactive sexual disorder is characterized by several symptoms including reduced pleasure in having sex, formation of keloid scars, and complications in the female reproductive system (Whitehorn, Ayonrinde, and Maingay 166-167). While FGM raises issues on human rights, it also influences the advancement of studies with regard to women’s health. Sexuality, as an issue concerning

An Analytical Study of the Earthquakes as a Natural Disaster Research Paper

An Analytical Study of the Earthquakes as a Natural Disaster - Research Paper Example â€Å"An earthquake is a series of vibrations or seismic (shock) waves which originate from the focus – the point at which the plates release their tension or compression suddenly†. Earthquakes involve the phenomenon where the earth surface shakes at certain points in time. It involves some kind of vibration that is emitted from deep within the earth's crust. Earthquakes result from some shocks that are remitted from within the earth's surface which is felt on the land and in the sea. Earthquakes often cause the damage of building and destruction of properties. The epicenter of an earthquake is the part of the surface of the earth which is the focus of the earthquake. Usually, the epicenter is the point on the earth where the highest impact of the earthquake occurs. Aside from the epicenter, the earthquake is felt in other lands around the epicenter. However, relative to the epicenter, the other areas affected by the earthquake is much lesser than that of the epicenter. Earthquakes are emitted by a series of shocks. There are some large shocks whilst there are other smaller shocks. These shocks shake the earth surface and are known as tremors. The tremors that occur before the earthquake are known as foreshocks whilst those that occur after the major earthquake are known as aftershocks. In terms of occurrence, there dynamics of earthquakes vary with the layer within which an earthquake emanates. Primary waves are body shocks in the earth's interior. The occur deep within the earth and close to the earth's core.

Education Requirements To become a physical therapist, one must have a masters degree in physical therapy from an accredited institute and a state license. Moreover, he should possess strong interpersonal skills so as to communicate with the patient and his family. The physical therapy job demands scores of patience from the practitioner.

Thw Cold War Essay example -- essays research papers

The Cold War as it is called was a war that started because of tensions between the United States and its allies and the Soviet Union and its allies. The tensions that developed were primarily over military, political, cultural and social ideas that varied greatly between the two nations. Each Nation and its allies developed a distrust that would last for many years and introduce new military and political methods that would shape our future. The Cold War was not a war as we would think with destruction and loss of life. What the Cold War became was distrust between Nations that caused conflict and tension between these nations. The two major countries involved in the conflict were the United States and the Soviet Union. Both of these nations distrusted each other and were unable to negotiate the issues that were fostering the Cold War because of the distrust that they had for each other. The United States and its allies were concerned that Russia was a communist county, ruled by a dictator who cared little about human rights The United States accused the Soviet Union of seeking to expand their version of communism throughout the world. Brittan and the United States (Led by President Truman) wanted to help Germany recover and to prevent large areas of Europe from coming under Communist control. They did not trust USSR since Stalin had signed the Nazi Soviet pact in 1939.Russia believed America was a capitalist democracy, which valued freedom. Stalin wanted reparations from G...

Sante Fe, Jamestown, and Quebec Settlements

Brianna Mosby Mr. Weigand DE U. S History 25 September, 2012 Settlements of Quebec, Santa Fe, and Jamestown Santa Fe Santa Fe was originally founded in1598 by Juan de Onate. He led a mining expedition of about 500 people. He hoped to find rich mines and rich lands. Onate expected the people, Pueblos, to help with the labor to find resources in the region. The mining trip was a bust and Onate and most of his people decided to head home, yet the Franciscan missionaries stayed behind in an attempt to convert the Pueblos to Christianity. 609-1610 is the date that archeologists say that Santa Fe was truly established by Don Pedro de Peralta. Before 1609, Santa Fe was inhabited on a very small scale. Spanish settlers lived amongst the indigenous population. The Pueblo’s population was reacing 100,000 people. They spoke nine basic languages and lived in about 70 multi-storied adobe towns. Santa Fe was thought to be almost abandoned by 1610 along with St. Augustine. The expeditions co st the mainland to much money to only come up with no results. Also there were notmany settlers attracted to this region.Overall the trips returned to little economic and strategic benefit to the Spanish. The only people to stay once everyone left were the Franciscan missionaries. After a few years the New Mexico region started producing a variety of goods to New Spain (Mexico). By 1680, the Pueblos drove the Spanish out of New Mexico for twelve years.. This was called the Pueblo revolt of 1680. Unfortunately for the natives the Spanish ended up coming back. Quebec Quebec was founded in 1608 by French settlers looking for a beneficial fur trade. As soon as the French landed they struck up an alliance with theAlgonkin, Montagnais, Huron tribes. These natives were the leading traders in the region. The French greatly benefited with this alliance, but it also brought a major problem. It brought a century of conflict with Huron’s enemies, the Iroquois confederacy from south of th e Great Lakes. Quebec was also called New France by the French. The leaders in New France pictured a simple, religious orthodox settlement with a handful of fur trading companies and a ruling class who owned agricultural estates. Once seeing the small number of French that came over the plans changed.The new idea was to converting the natives to Catholicism, French culture, and a simple lifestyle of farm labor on the estates, yet few chose this option. Instead most of the young Frenchman decided to live like the Native people as fur trappers and traders living in the backwoods. The French population struggled the first year on the new land. They started out with a small population. The first winter did not help by killing off most of the immigrants. For years after the only people alive were the missionaries and fur traders. By 1627 the population of the French in New France was only 85.New France was able to keep its roots down is due to the developed economy and social systems tha t were organized around a single product. The single was product was fur trading. It was essential to the French, it kept them stabilized and on good grounds with the natives. The New France settlement was an overall peaceful thing. There was never an actual war for land between the natives and the French. The only thing that saved them from having this problem was the small numbers in population. They had a very small demand for the Native’s land, also the policy of the alliance put even less pressure on the indigenous peoples.Jamestown Jamestown was established in 1607 by Captain John Smith. He sailed over on a charter from King James I with Virginia Company explorers. The Chesapeake region was chosen partly because the English knew who controlled it, the Powhatan people. English settlers expected to receive food and help with tributes in valuable goods. The explorers were mostly military men who were prepared to explore, deal with the Indians, and seek out riches in the ar ea. They were not prepared to grow food crops or fish. When times started getting rough they decided to raid the surrounding Powhatan villages for food.The first few years were the worst any of the settlers could have imagined. They dealt with famine, disease, frigid winters, failing harvests, and Indian wars. By 1610 the settlers decided to abandon Jamestown and head back to the homeland with a population of sixty. Nearing the end of the James River the settlers ran into their new governor who came with supplies from England. He ordered them to turn around and go back to Jamestown. English and the North Americans traded, negotiated, cooperated, and intermarried with each other. The settlers came into conflicts over land and their demand for the Native’s land.They also excluded the Powhatan people from their society. Eventually the New World started to flourish once the English accepted the Powhatan people. They became a key factor to the new tobacco economy in colony, changi ng it to a cash crop in 1613. English leaders on the expedition planned to have a ruling class of wealthy families who owned estates in the New World that were worked by bound laborers. At first the landowners had a hard time keeping the English servants bound to labor until the use of enslaving Africans. All Together Overall these three settlements have much in common yet differ just as well.Starting out all three were new expeditions to unknown territories. They all promoted strategic expansion plans to match and exceed their rival’s alliances and territorial gains. Also each out â€Å"established† a church and prosecuted dissenters in one way or another. Another thing is that they all had a bound labor system, it just varied in each settlement. They were all familiar with types of servitude and slavery in some way. All though they are alike, they are different. It starts off on where they settled Spain: New Mexico and Santa Fe, England: Jamestown, France: Quebec.The Spanish and French lived with the natives and allied with them, while the English excluded the Powhatan and raided them. Also the French was the only settlement to not go to war with the natives. They depended on the on the natives and did have such a threat to them because of the small population.

BDNS utility Essay

Till now, to run BUSY Client-Server model on Internet, you need to obtain a static IP on the Server. But with the coming of the BDNS utility, there is no need to obtain a static IP. By running BDNS utility on both Server and Client machines, you can easily connect both the machines and can work as you work in Client Server model of BUSY on Internet. BDNS utility works as a mediator to connect the Server and Client machines. On the Server machine, you need to specify a name for your Server and name of Client machines that can connect to the Server with a password with each Client to validate the Client machines. Similarly on the Client machine, you need to specify name of the Client and name of Servers to which you want to connect and the password to connect to the Server. This password will be the same as specified with the Client name on Server machine. For example, on the Server machine, you have specified Server name as GRTraders@mail.com@bdns, Client name as GRTClient1 and password as abcd. In this case the Client machine can connect to the Server by specifying the Server name as GRTraders@mail.com@bdns, Client name as GRTClient1 and password as abcd. Working of BDNS Utility BDNS utility works in a peer to peer model. In this model, both the Server and Client machines are connected through a public Server which acts as a mediator. Both the Server and the Client machines send their request to the mediator by giving their own name and the Server and Clients they are searching for along with a valid password. When the mediator finds a similar combination of Server and Client machines along with password which are searching for each other, it then does handshake of both the machines. Handshake here specifies that both the machines are now connected with each other. Given here is a pictorial representation of working of BUSY DDNS utility. BDNS utility connects Server and Client machine through a public Server or Mediator hence there are simultaneously many Servers and Clients that want to connect to each other. This increases the possibility that there are more than one Server and Client machines with similar names that want to get connected. For this purpose, we recommend that you give a unique name to your Server machine. Selecting Server and Client Names Although there is no validation for Server and Client names and you can give any name of your choice but it is strongly recommended that you give unique name to them. This should be done to avoid cross connection with other people Server. Do not give generic name such as Server or Server1 to your Server machine as it is possible that other people using the same utility can give this name to their Server machine also. It will only lead to cross connection between the Servers. For example, one of your Client machine is trying to connect to the Server machine and your Server machine is switched off at that time. A computer with similar Server name is connected at that time. In this case the Client machine will try to connect to that Server but as the password will not match it will give an error message that password is incorrect. In this case, the Client can get confused as it has given the right password and is still not able to connect to the Server. This is because it is trying to connect to a different Server which is having the same name. Hence to avoid such type of confusions, you must give unique name to your Server. To make your Server name unique, you can give your Email ID as your Server name as Email ID is always unique or you can give your firm’s or company’s name to the Server. For example, your Email ID is GRTraders@mail.com then you can give Server name as GRTraders@mail.com@bdns. The Server name must always end with ‘@bdns’.

Population Growth 1750-1830 essays

Population Growth 1750-1830 essays In this essay we are going to consider the population growth from 1750-1830. The basis for the material is taken from the "Macmillan Series, Mastering Economic and Social History" written by David Taylor. In his book, Taylor gives several reasons as to why the population increased between 1750-1830. He argues that the practice of living-in disappeared, there was a decline in apprenticeships, and the speenhamland allowance encouraged large families. He also concluded that the general well-being of the people improved though diet. There's no one explanation as to why this happened, or one history. It may have been the fall in the death rate and the increase in the birth rate. Up to the nineteenth century no official census had taken place. In 1086 the Doomsday book placed the population at about 3.5 million. Attempts were made at counting the population in the seventeenth century by Gregory King a civil servant. Nevertheless, it proved unreliable and was more or less a guesstimate basing his figures on hearth-tax returns and parish records. Taylor states concerning Gregory Kip^i M(ie estimated the number of people living in a house and gradually built up a cumulative total of people of the whole country - the figure he arrived at was 5.2 million". The first official census was taken in 1801 and has been conducted every ten years apart from 1941. The population was low before 1750 owing to a number of factors. "Between 1520 and the end of the seventeenth century the population of England and Wales seemed to have risen from about 2.5 million to about 5.2 million. This contrasts with the fact that the population had risen hardly at all since the Black Deat h, and from 1650 to 1750 it rose only by a further million. Interrupted by bad harvests, with or with out outbreaks of plague, influenza, smallpox and dysentery in 1550s, 1580s, 1590, and 1630s". (A new History of England 410-1975) The bubonic plague of 1665 also took its toll on the po...

Top French Romance Films

Top French Romance Films Well, they say French is the language of love, so what better language to watch romantic movies in? Cyrano de Bergerac   A beautiful, touching, and humorous love story. Cyrano loves Roxanne but fears rejection due to his overly-large nose. Roxanne loves Christian, and he, in turn, loves her but does not have the ability to express his love. Cyrano helps Christian by expressing his love to Roxanne via Christian. This is the original film, made in 1950 in black and white. It has been remade a few times, including in the US as  Roxanne, with Steve Martin. Le Retour de Martin Guerre (The Return of Martin Guerre) Gerard Depardieu plays a soldier who returns to his wife after many years and has changed so much (in more than just personality) that his wife and neighbors are not sure its the same person. A beautiful love story as well as an interesting look at medieval France. Remade in the US as  Sommersby, with Jodie Foster and Richard Gere. Les Enfants du Paradis (Children of Paradise) A classic French romantic movie, by Marcel Carne. A mime falls in love with a theater troupe actress but faces a lot of competition for her affections. Shot in black and white in 1946 (while Paris was under German occupation), but set in the 19th century. Its a must see! La Belle et la bà ªte (Beauty and the Beast) Youve probably seen some version of this classic French romance, but the original- in black and white- is by far the best. This beautiful, sensual film by Jean Cocteau is about love, inner beauty, and obsession, and is nothing short of a magical fairy tale. Baisers volà ©s (Stolen Kisses) This sequel to 400 Blows (Les Quatre Cent Coups) couldnt be more different to its predecessor. Antoine loves Christine, who is indifferent until her admirer falls for another women. Christine then realizes (decides?) that she does want him after all, and tries to woo him back. A very sweet movie by Franà §ois Truffaut and Jean-Pierre Là ©aud. Les Roseaux savages (Wild Reeds) Andrà © Tà ©chinà ©s 1994 film, set in 1964, is a beautiful coming-of-age story about four teenagers and their experiences with relationships and the effects of Frances war in Algeria. Beautiful cinematography and a great soundtrack, to boot. This film won 4 Cà ©sar awards. Les Nuits de la pleine lune (Full Moon in Paris) A wonderful romantic comedy and the fourth installment in director Eric Rohmers Comedies and Proverbs series. Louise (played by the talented Pascale Ogier, who tragically died the year the film was released) grows bored with her lover and decides to spice up her (love) life. Humor and tragedy ensue. LAmi de mon amie (Boyfriends and Girlfriends) Another from the Comedies and Proverbs series, this film looks at love and friendship. Which is more important: passion or companionship? Is boyfriend-swapping really such a good idea after all? Find out with this movie. Une Liaison pornographique (An Affair of Love) Dont let the ironic French title put you off; this is a beautiful, erotic love story about two people who meet looking for anonymous sex but end up finding much more. A beautiful and mysterious tale of love. LHistoire dAdà ¨le H (The Story of Adele H) The true story of Victor Hugos daughter and her obsession with a French lieutenant. Not a happy story, but certainly a beautiful and intriguing movie.

Healthcare Reform Essay Example | Topics and Well Written Essays - 750 words - 1

Healthcare Reform - Essay Example Health care reforms have led to many bureaucracies within the health care industry. For example, before a person can be attended to, he or she must produce identification documents. The medical personnel has to ascertain that you are who you claim to be and whether you have medical insurance. This screening process is flawed be against the poor who cannot afford medical insurance, as well as the illegal aliens in the country. These reforms have made the medical process slower in its service delivery, with the constant paperwork required to start the medical process. The long and prolonged processes lead to prolonged delays.Even as I oppose health care reforms, there is one undeniable counter argument in regards to these reforms. Health care reforms have led to the incorporation of technology within the health care industry. Before technology, processes like record keeping were tiresome because medical personnel could not keep track of which records were required for a specific task. There were constant mix-ups with information being put in the wrong files and documents, but the introduction of technological equipment such as computers has made work easier. Large quantities of data regarding the patients could be entered into computers and could be easily retrievable for use by the medical personnel. Technology has also enabled the monitoring of patients easier with the emergence of wireless and wearable medical devices, which alert the medical personnel of any issues that might arise remotely.

DNA Sequence Analysis Coursework Example | Topics and Well Written Essays - 1500 words

DNA Sequence Analysis - Coursework Example Open reading frames (ORFs) shall be selected from he solution of suggested on the web based platform. Before then the linear DNA sequence is checked and the first graph shows us the location of restriction enzymes and their point of action. What follows is the choice of primers that would match the segment of DNA sequence chosen for this case wasEL784663 from our observation the following primers would be the most appropriate:- At a temperature of between 50-65oC, the pUC18 plasmid vector is digested by any of the restriction enzymes found at the multiple cloning sites (MCS) to make a single cut in the plasmid. This shall make the otherwise circular dsDNA module to become linear which will enhance its ability to coalesce with the DNA sequence that has been cut with the same restriction enzymes. The ORFs are then cloned in the amplified into the pUC18 to ensure that the DNA is transformed into chemically competent E. coli. During cloning EcoRI (5... GA  A  T  TC ...  3) site was preferred because it matches both the MCS restriction enzymes and the restriction enzymes of the linear graph of the DNA sequence chosen. However it is not in the sequence it is just outside the chosen sequence. This means that the selected primers require additional bases so that the EcoRI cuts the two sites at the same time during the Polymerase Chain Reaction. The protein has several biological functions and of importance is for example in biological folding, regulation of transcription, DNA binding, heat shock protein binding. The protein is usually in existence during the transcription stage of DNA sequencing and polymerase chain reaction. In protein folding process it’s where functional shapes of proteins are shaped from the constituent polypeptides. It involves the use of both covalent and non covalent bonds are made to coalesce in the required shape. This protein is in the DNA and is usually instrumental in this kind of process (Kieleczawa,

Financial management Essay Example | Topics and Well Written Essays - 1500 words - 1

Financial management - Essay Example Key principles that are followed by the Panel on Takeovers and Mergers are as follows: First, the panel follows the principle of equal treatment for every shareholder. According to this principle, every shareholder of the firm that is getting taken over should get equal treatment. Even if all the security holders do not posses adequate control on the operation of the company, each of them should be protected. Second, the panel strictly follows the rule of providing adequate advice and information timely to all security holders. Third, the panel can not allow the creation of any false market for the shares of the offeree firm. According to this principle, a company is allowed to announce a merger or takeover only once after it becomes completely ready for the event to conduct. Fourth, it is not possible for any firm to perform any unauthorized frustrating activities without having any approval from its shareholders. According to this principle, a firm can not issue or sell any share f rom its treasury without proper approval from its shareholders. (Fisher, 2003) B. The Economic reasons for mergers and acquisitions are some economic benefits that are obtained by means of mergers and acquisitions. The benefits are as follows: Efficiency: Mergers and acquisitions help firms to add up their assets. ... Besides getting efficiency at operational level, mergers and acquisitions also help in providing efficiency at management level to some extent. When a firm involves in the process of merging with another firm or taking over the assets of any other company, then it becomes possible to generate a market controlled by corporate. (Hunt, 2009; Sherman and Hart, 2006) Financial benefits: By taking over the assets of other firms, a business organization can follow the route of diversification of its earnings. This type of diversification causes a significant fall in the variation in the area of profitability of the company and thus helps in making a reduction in the risks of bankruptcy as well as attendant costs. Market power effect: Mergers and acquisitions is also helpful in providing greater amount of market power that in turn offers many benefits to the companies who involve in the process of merging. (Galpin and Herndon, 2007) Sometimes mergers and actuations become unsuccessful for th e following reasons: First, mergers influence organizational culture to a large extent. On account of mergers and acquisitions the employees of the merging companies have to experience rigorous anxiety. This kind of anxiety causes a fall in the level of productivity. Second, frequently, mergers are done with wrong intentions. Often, mergers or takeovers are used for seeking glory or to express financial strength. Third, the success derived from mergers and acquisitions is frequently hindered by variations in the work cultures as well as corporate activities of the firm which are involved in the process of mergers and acquisitions. Fourth, once the process of mergers and acquisitions becomes complete, firms generally put their focus on the issues relating to cost reduction rather than

Mobile Sensor Network for Indoor Environment

Mobile Sensor Network for Indoor Environment 4 node sensor network without collisions. Update of every sensor reading in the network at least once per second (available from all nodes). Single frequency channel (i.e. no frequency multiplexing permitted). Error checking (CRC) included to ( Measure at least 2 parameters (e.g. temp, light..) Data presented on serial I/O port in a format that is easily readable on a text terminal. 1. Background knowledge 1.1. System structure The aim of this coursework is to design a mobile sensor network for an indoor environment, communicating with a 2.4 GHz wireless link (IEEE 802.15.4). All the sensor nodes can realize data link, which means each board can get others information. All the sensor boards have the function of receiver link to the computer, and can present the sensor data (for all nodes in the network) to the serial I/O port in a format which is easily to be understand on a text terminal. If the nod which connected to pc is broken, the other 3 nodes can replace it and realize the function of receiver. Each sensor node will include a number of sensors interfaced to a microprocessor (for our group temperature, sounds, touch and light). The microprocessor will gather sensor data, communicate with other sensor nodes via a wireless transceiver, implement a network protocol and provide a PC interface via a serial I/O port for data display. The structure of whole system is as follow: Figure 1 Architecture of Wireless Sensor Network 1.2. Basic hardware The principle hardware used in this project is the PICDEM Z [3] development board from Microchip Technology Inc. There is a PIC18F4620 microcontroller on every node board and every group has 4 board available. The PICDEM Z has a prototyping area which must not be used for circuit construction. First, we need veroboard to construct a circuit, then interface it to the header J6. The next figure shows the structure of the board. Figure 1 The structure of the board And we also have other devices can use in this course: 1. 9V DC power socket (J1) for operation from mains adaptor. 2. 9V battery terminal (BT1) for mobile operation. 3. ICD connector (J5) for connection to MPLAB ICD3 in-system programmer/debugger cable. 4. RS232 serial port connector (P1) for connection to PC COM port. 5. Microchip MRF24J40 2.4GHz transceiver module connected to J2. 6. LEDS RA0 and RA1 for indication. 7. Push buttons RB4 and RB5 for simple logic input. 8. Header J6 giving access to analog and digital I/O pins Vcc (3.3V) and GND. This may be used to interface additional sensors. 1.3. Microchip MRF24J40 2.4GHz The MRF24J40 wireless transceiver [5] provides the physical layer for your wireless communication network. This is a 2.4GHz (IEEE 802.15.4 compliant) device which transmits data rates up to 250kbps and is connected to the PIC via SPI bus, as well as a small number of digital I/O pins. The picture of Wireless transceiver is as follow. 1.4. MPLAB-ICD MPLAB-ICD is an inexpensive development tool for MICROCHIPs PIC16F87X series MCU. MPLAB-ICD is an online debugger, and a programmer. It works in the MPLAB-IDE integrated development environment, and use online serial programming technology of MICROCHIP (In-Circuit Serial Programming), the monitoring program is embedded to achieve real-time simulation in the simulation of the MCU (PIC16F87X). The simulation head is directly connected to the MCU socket of the application system, running the users application as a PIC16F87X. The picture of MPLAB-ICD is as follow. 1.5. Wireless sensor network Wireless Networks use radio waves, infrared, or any other wireless media to link to any devices. It can cover a large area, in which case it will be called a Wireless WAN, or it can cover an area or some floor of building, such as school, hospital and railway station, in that case Wireless LAN (WLAN) appear and describe the situation[4]. It appears a large number of wireless communication standards nowadays, including ZigBee, Wi-Fi, WiMax, GSM (Global System for Mobile Communications) et al. Wireless sensor network (background) became a more and more popular way to solve the problems of large-scale tracking and monitoring applications because it has low-data-rate, low-energy-consumption, and short-range link network [1]. It give people a chance to monitor and control the physical world in a more simple way. WSN applications include many ways in our life, such as industrial monitoring, security, electronics industry, military sensing, asset tracking and home automation. WSNs research has mainly pay attention to energy consumption, routing and data transmission, particularly focusing on collecting and data summary in specific networks with an associated sink node, called a WSN gateway [1]. Some research has carried out the interface of different sensor networks for a single or complex applications. Wireless sensor networks is aimed to monitor and control the physical data of environmental conditions at remove locations and it can collect their data to a main location and send their control command to achieve the result of remote control. A WSN includes plenty nodes, ranging from a few to hundreds and thousands, in addition each node may be linked to one or more other nodes. One node can be designed for carrying out one or more different sensors which have various functions and we can also design combined sensors choice to complete complex use or exchange data with another network[4]. A node for sensing is called a sensor node, everyone can collect the data of other sensor node. As a result, any place with a sensor node can get all the data with a very fast speed at any time. 1.6. Error detection Cyclic Redundancy Check Error detection segment is necessary in a data transmitting system since the correctness and efficiency of data transmitting must be ensured. In this project, there are 3 approaches which can be applied to error detection: parity bit, check sum and cyclic redundancy check (CRC). Parity bit is also known as check bit, the function of which is to judge whether a number of 1-bits in the string is even or odd by adding a bit to a string of binary code. The realisation is that the bits with value 1 is counted for even parity while the coding reverses for odd parity. Although parity bit is easy to implement, the shortcoming is apparent that only when there are 1, 3, 5, à ¢Ã¢â€š ¬Ã‚ ¦ bit(s) errors can the error be detected. The principle for check sum is to define a string with a small size with designed algorithm of calculating, and the result of the calculations of before and after the transmitting will be different even the data changes slightly so the error could be detected in this way. Similar to parity bits, the disadvantage of check sum is that error cant be detected under some circumstances. Cyclic redundancy check (CRC) is a method of error detection that is easyto be implemented by shift register and look-up table in S/W. The process is shown in figure1. In this project the value of P(z) is 0x91 (11001 in reversed binary) which is known as generator polynomial and the divider. Assuming that the data needed to be transmitted is 110011000, then we have the message polynomial D(z). C(z) is the remainder which is calculated by D(z) divided by P(z). The realization of division operation is by XOR. Only when the least significant bit of 1 byte of the message is 1 will it XOR with CRC polynomial, then we should shift it to the next bit and repeat the XOR. At the transmitter, the string of CRC depends on the whole frame on a bit-by-bit basis with binary division. And at the receiver, the received bit string is again divided by the same bit-by-bit basis with a serial shift register. The resultant CRC result should be all zeros at the end of the frame, or there must be errors in the process of data transmitting. Grahame Smillie, 10 Bit error detection and correction, In Analogue and Digital Communication Techniques, Butterworth-Heinemann, Oxf ord, 1999, Pages 185-230, ISBN 9780340731253, http://dx.doi.org/10.1016/B978-034073125-3/50012-7. 2. System Design 2.1. Sensor design and calibration and Analogic digital converter ADC In our group 4 kinds of sensor are designed to meet the requirement, and they are temperature sensor, light sensor, touch sensor and sound sensor. In order to obtain data from all the 4 sensors in the wireless network, a PCB board is required to connect to the sensor node board. In the lab, a breadboard is available for testing the circuit. When finishing the circuit on the breadboard, it can be interfaced to PC to have a preliminary test. If done, a PCB board will be used to finish the final product which can connect to node board. The method of calibration is to get the value of light, sound, temperature or touch that is detected using physical measurement. For example, if the temperature of the environment T0 and the result of the ADC conversion D0 that collected by the sensor in the same testing environment are known, we can derive the proportional function of temperature and ADC data with another pair of coordinate (T1, D1), which is obtained by changing the temperature of testing. Then the code that controlling display of temperature value should be modified so that by the time the temperature of the environment changes, the displaying value on the PC is exactly the temperature. Code for this part is shown as following: 2.1.1. Temperature sensor Negative Temperature Coefficient (NTC) thermistors are temperature sensitive semiconductor resistors which decrease in resistance value when absolute temperature increasing. Change in the resistance of NTC thermistor can be brought about either by a change in the ambient temperature or internally by self-heating resulting from current flowing through the device. (NTC Thermistor Discs and Chips | Ametherm, Ametherm, 2017. [Online]. Available: http://www.ametherm.com/thermistor/disc-and-chip-ntc-thermistors. [Accessed: 07- Jan- 2017].) Most of the practical applications of NTC thermistors are based on these material characteristics. Time and temperature are two of the most frequently measured variables. There are various ways to measure temperature electronically, most normal is by thermocouples and negative temperature coefficient (NTC) thermistors. In addition, NTC temperature sensors can operate over a wide temperature range (-55 to +300 °C). They are stable throughout a long time, and are small and cheaper than other kind. [3] Figure 1 circuit of Temperature Sensor It can be seen in the figure 1 that temperature Sensor is a more complex circuit design. On the left part It=Vcc/(R1+Rt) and Vt=Vcc*Rt/(Rt+R1), then connect the line to the positive side of the LM358 amplifier to amplify circuit and Vt becomes the input of the amplifier. After that, use formula V0 = Vt*(1+R3/R2) to get the voltage value of v0. From this formula we can know, the value of V0 depends on R3 and R2, so R3 and R2 are both simply chosen 10 Ohm. Then the voltage value of V0 is exactly twice as much as that of Vt. Next use formula to transfer ADC data to temperature, when it comes to the lab temperature (23 degrees Celsius), ADC data is 613. While it comes to the people body temperature (abort 38 degrees Celsius), ADC data become 530. Finally, we can calculate the linear parameters by these two sets of data. 2.1.2. Light sensor The Light Sensor is a passive devices that transfer light energy visible or invisible into a output of voltage signal. Thus Light sensors are more commonly known as Photoelectric Devices or Photo Sensors [2]. Photoelectric devices can be classified into two main categories, those which generate electricity when illuminated, such as Photo-voltaics or Photo-emissives etc, and those can change their electrical data (voltage) in some way such as Photo-resistors or Photo-conductors. [2] Light sensor is the easiest sensor of our 4 sensor, so we also use the simplest structure, when luminance become strong, the value of photosensitive resistance become larger. Thus the voltage of Vt increase which result in the raise ADC data. Then use formula to transfer ADC data to luminance, when it is dark (lux 0), ADC data is 30. While it comes to the lab light (about 330 lux), ADC data become 895. Finally, We can calculate the linear parameters by these two sets of data 2.1.3. Sound sensor 2.1.4. Touch sensor The MPR121 is the second-generation sensor controller after the initial release of the MPR03x series devices. The MPR121 will feature increased internal intelligence in addition to Freescales second generation capacitance detection engine. Some of the major additions include an increased electrode count, a hardware configurable I 2Caddress, an expanded filtering system with debounce, and completely independent electrodes with auto-configuration built in. The device also features a 13th simulated electrode that represents the simultaneous charging of all the electrodes connected together to allow for increased proximity detection in a touch panel or touch screen array [5]. 2.3. Time Division Multiple Access TDMA It is required that there are at least 4 nodes of sensor without collision in a wireless transmitting network based on a certain channel. Each sensor must be ensured to be able to receive and transmit, in other words, each node can serve as both a receiver and a transmitter. The node which connects to the PC is responsible for the display of the data that collected by each sensor and each sensor is supposed to send the data string to the chosen node within 1 second. There will be collision with the four nodes if we dont define the order of the data transmitting and receiving or just simply define by applying time delay, hence TDMA is necessary to meet requirements above. TDMA is a method of communication technique that derived from the P2S (parallel to serial) conversion. In the process of TDMA of this project, receivers obtain a same signal at the same time but only the appointed receiver reacts and does the next action, which is then transmitting and serving as new transmitter, and the new transmitter will wait for the next appointment without doing nothing unless it is appointed once again, which means it gets the same order in a new loop. The process repeats and there will not be data collision in the transmitting and receiving. As is illustrated in figure2, there are 4 nodes so 4 slots are needed in 1 second according to the requirement, hence each slot takes up 0.25 second, during which time of period each node should finish data transmitting, so the calculation of the time that is needed for sending and receiving is necessary. 2.3.1. Data packet structure 2.3.2. Timers We apply timer0 to control the time of running, different initial values have been given to timer0 in each slot so that transmitting and receiving within 1 second without collision can be ensured. In this case, node 4 is the main node which connects to the PC. The start of the process is the transmitting of node 4, and by the time other 3 nodes receive data from node 4, the text packet ID of the transmitter will be checked and only node 3, which is the transmitted ID 4 minus 1, will display the data that collected by node 4 and transmit its own data collected by its sensor. Following actions will be carried out by node 2, and node 1 within a certain time of period, like shown in figure3. Figure3 4. IoT Data Service and Visualisation

Postponing Motherhood Essay -- Pregnancy Birth Children Short Stories

Postponing Motherhood As a senior in a small high school in Connecticut, Jane Swanson* was attending weekly volleyball team practices, planning for college, studying for tests, and spending time with her friends and her boyfriend. She was a typical teenager until, at 17, she learned that she was pregnant. Stunned by the news and unsure of what to do, she spoke to her friends about her options. She was especially surprised because she was using condoms and practicing safe sex. Sadly, half of the 1.3 million women having abortions each year used some form of contraception when they became pregnant. She quickly realized that with her friends being teens themselves, they couldn’t give the best advice, and decided to call the nearest Planned Parenthood in Connecticut. Planned Parenthood is one of the best-known resources for abortion services. About to celebrate is 75th year, it is well known for promoting sexual and reproductive health through â€Å"clinical services, education and advocacy.† "Caring professionals provide a wide range of services in our modern facilities. Our clients know they can trust us to provide confidential and comprehensive health care at a reasonable cost,† wrote Dianne Luby, President and CEO of the Planned Parenthood League of Massachusetts, in her public address published on the clinics’ web site. Swanson spoke to a receptionist who informed her of the different types of abortions, medical and surgical, and also urged her to come into the office as soon as possible. She added, however, that that particular clinic did not perform abortions and she would have to travel a significant distance, to Hartford, for the procedure. The National Abortion Federation, through its 350 member clinics and... ...ake the decision to abort,† said Brown. â€Å"They fear being cut off from their families, their education being interrupted, their finances, that their boyfriends would leave them. They’ve already made up their minds.† A branch of A Woman’s Concern includes â€Å"Healthy Choices,† a five-day program in middle schools and high schools aimed at educating young people on unhealthy behaviors, misconceptions in the media, and lesson in skill building, designed to teach the students that they have a voice. "Healthy Start† has visited eleven or twelve different schools in and around the Boston area so far this year, and has received a positive response. Two years after having an abortion, Swanson, is still confident that she made the right decision. "There is no shame in getting pregnant, or getting help,† Swanson said. â€Å"Looking back, I only wish I had told my mother.†
