A look into sectarian academic institutions selective student admission policy

A look into sectarian academic institutions selective student admission policy Hashtag: #TiwaLaSalle (â€Å"Trust in La Salle!† University) The Nature of Sectarian Schools About four years ago, several schoolchildren with lesbian parents were rejected by a Catholic school in Boston, Massachusetts. A Lutheran High School in California, on the other hand, expelled two students simply because they were members of the third sex. Sectarian schools are also famous for rejecting students with different religious belief, of different skin color or with a physical or mental disability, but gets away with it. How is that possible? Sectarian schools are private institutions, as they do not receive funding from federal government or directly administered by the state. For this reason, sectarian schools are self-governing entities with freedom to discriminate or reject a particular type admit a certain type of student. Therefore, those shouting #TiwaLaSalle are students who passed the discriminating standard of the university and deserving of education for the elite. Owners of sectarian schools are either Catholic or Protestant religious organizations aiming to propagate and advance their respective religious beliefs. A sectarian school, therefore, is only open to students with similar faith. Moreover, since government or people’s taxes do not fund private organizations, students in sectarian schools are normally sons and daughters of parents who can pay expensive tuition fees and support expenses associated with exclusive education. Get your portion of inspiration here: Why High School Years Are Often the Most Memorable in Later Life? What Are the Common Problems faced by Students in School? Relieving Students School-Related Stress High School Is a Must-Do? At School, I Have Been Bullied by a Teacher Discrimination in Schools of the Holy Most sectarian schools are named after a patron saint or religious figures (ex. Saint Anthony’s College, La Salle University, Saint Francis Xavier University) but their practices seem far from being divine. They continue to exist and operate under the law regardless of the fact that denying student’s admission on religious grounds result in racial exclusion and violation of children’s rights. Under the law, sectarian schools as private educational institutions can have different rules. For instance, a Roman Catholic nun and leader of a Catholic school in New Orleans openly admit that students and faculty have limited rights in a Catholic school. In fact, they are free to ignore freedom of speech and due process rights, hire and fire staff on religious grounds, employment regulations, and reject admission of anyone mainly because they are ministries funded by private donations. These practices according to school official are not religiously bias but simply a matter of choosing those who are members of the church. Moreover, since the school is part of the ministry, they need to model and protect Catholic values. This may be true as most textbooks according to the study of Christian schools are politically and religiously bias and often identical to materials produced by partisan organizations promoting conservative Christian ideas. Discriminatory practices of sectarian schools such as those promoting Catholic values, in particular, seem contradictory to Christian teaching. For instance, discrimination is never a Christian value. In fact, Jesus, through his ministry, emphasized the need to love one another, as God’s love for all is unconditional. Evidently, these include those we deemed unworthy or people with different belief, gender, and race. Sectarian schools should realize that independence from government funding and control does not necessarily mean freedom to discriminate and promote false religious values such as providing exclusive education for the elite.

Modern finance Essay Example | Topics and Well Written Essays - 2500 words

Modern finance - Essay Example (Campbell, 2008). Apparently, the current crisis may be attributed to the subprime lending made by the different financial institutions. However, at the core of it is a whole plethora of different variables which are not only correlated with each other but also created a combined effect on different macroeconomic variables too. The failure of financial institutions to regularly check in their appetite for taking more risk not only resulted into the current credit crunch but also indicated the degree of the regulatory control over such institutions to discipline their behavior. Northern Rock is such a financial institution in UK which required intervention from the government because of its apparent failure to sustain the losses incurred due to subprime mortgage episode. In this research study, the current credit crunch will be discussed with special focus on Northern Rock as a firm requiring official intervention. The credit crunch started to emerge during 2007 when in US, especially financial institutions started to witness defaults on payments of subprime mortgages. Subprime borrowers are termed as those borrowers are who have relatively high risk due to their past credit history. Therefore, under normal banking rules and practices, lending to such borrowers are riskier as in comparison to other borrowers. It is because of this reason that such borrowers are categorized as subprime and are charged relatively higher rates on the lending made to them. Historically, banks were more conservative in their lending practices and avoided to lend to such borrowers who lacked the capability to repay. However, with the innovation in the financial markets corroborated by liberalization of financial markets allowed financial institutions to innovate and roll out products which carried relatively high risk. This phenomenon was further aggravated with the globalization of the financial markets

How Would you physicalise a charcter from a play Essay Example for Free

How Would you physicalise a charcter from a play Essay Too physicalise a character from a play you need to have studied the specific character in a reasonable amount of detail, so you can portray them correctly. To do this effectively you need to do various exercises, all which will help you grasp the character the best you can. There are several methods which can help you to understand a character eg: Hot Seating, Spider Diagrams, and Workshops etc. In our lesson we explored the character by Hot Seating, Character Profiles and other exercises. Hot seating is an extremely effective method, as it puts you on the spot answering various questions in your characters persona. It helps lock in the information about the character you’re playing. You need to understand the questions being asked from your characters point of view so you can understand who your character is and why. We used this method in our lesson, and i found it was an effective way of physicalising a character. Another exercise we did in class which was effective was one where we were told to hold a pose in the form of our character then walk around the room in the characters style. This is a great exercise because although Hot Seating, Profiles are good they focus mainly on the psychological side, where as this focused on the physical aspect of the character. Character Profiles I believe are an essential tool in bringing a character to life. Because it allows you to go deep in to the information about the character, their background, family life, nationality etc. These aspects are what form how a character behaves and why they feel certain things. For example Stanley in Street Car Desire, has a particular hatred for being called a ‘polak’ as his family originates from Poland and deems the phrase derogatory towards them. Spider Diagrams are effective in showing your characters relations with other characters in the play. These are essential to know as it may influence why the act a certain way around someone. How did you explore the use of Verbal and Non=Verbal.

Human Genome Project Essay -- Genetics Science Biology Essays

Human Genome Project Human curiosity is one of the most powerful engines that drive new knowledge, development, advancements and life improvements today. Some 100,000 or 200,000 years ago Homo sapiens emerged, and up to today humans are still searching for answers such as what we are and where we came from. For all of the diversity of the world's more than five billion people, full of creativity and contradictions, every human mind and body is built and runs with fewer than 100,000 kinds of protein molecules. And for each of the proteins, a single corresponding gene is responsible to ensure an adequate and timely supply. Genes are often described as the biological blueprints or recipes for life and are found in the DNA, carrying the genetic information from one generation to the next. Many people are convinced that genes are special, that they contain a person's essence, which has enormous spiritual and commercial value. In the deepest sense, we are who we are because of our genes, and therefore it is essential to gain knowledge about the manifold mysteries of life, our genes, and our biological inheritance in full ultimate molecular detail. With advances in molecular genetics, it became possible to launch the Human Genome Project (HGP) - a sequencing project that determines the genetic makeup of an organism by reading off the sequence of the three billion DNA bases, which encode all of the information necessary for the life of the organism. Profits, curiosity and dreams of better methods to prevent and treat diseases are driving efforts to find and decode human genes.

Japanese Comfort Women Essay

It is estimated that between one and two hundred thousand female sex slaves were forced to deliver sexual services to Japanese soldiers, both before and during World War II. These women were known as comfort women and the Imperial Conference, which was composed of the emperor, representatives from the armed forces and the main Cabinet ministers, approved their use by Japanese soldiers. Walkom) The term â€Å"comfort women† refers to the victims of a â€Å"premeditated systematic plan originated and implemented by the government of Japan to enslave women considered inferior and subject them to repeated mass rapes,† said Michael D. Hausefeld, one of over 35 lawyers in his firm representing the former sexual prisoners in a class action lawsuit currently pending against the Japanese government. (Eddy) Since ancient times, prostitutes in Japan chose to sell their bodies either for family, poverty, or for saving her husband and her children. More or less, their sacrifices were seen as positive. But, being forced to become comfort woman by Japanese is seen as negative. The difference between the Japanese prostitutes and comfort women is that the comfort women did not choose to be trapped as a sex slave and they were not paid for what they did. In 1931, when the Japanese army invaded Manchuria, â€Å"comfort houses† made their first appearances. These comfort houses were created to provide the Japanese soldiers with outlets for their sexual needs. In the beginning, there were only a few comfort houses but after the Nanjin Massacre occurred in 1937, many more were added, basically to every place that the Japanese were stationed. (Walkom) After the Japanese soldiers slaughtered thousands of Chinese people in the Nanjin Massacre, they barbarically raped an insurmountable number of women. As a result, anti-Japanese sentiments grew and it became harder to fully occupy these lands. The government set up comfort houses to decrease disorder and give the approximately two million soldiers a place to satisfy their sexual needs. The Japanese did not have enough prostitutes to supply the needs of the soldiers so they commissioned civilians to develop comfort houses. At the time, only a small percentage of Japanese women were mobilized to â€Å"work† in comfort houses and they were all prostitutes to begin with. The majority of the comfort women were actually Korean women, who were forcibly taken from Korea to service the needs of the Japanese soldiers. After the war, the Japanese government destroyed all evidence of their involvement in Japanese comfort houses, enforcing that commercial businessmen were responsible for the movement of women. Many of the comfort women were kidnapped or deceived into voluntarily working in comfort houses. Once they were there, they were trapped and forced into prostitution. Some women reported that Japanese agents offered them good jobs or education. Others were told that each family in the village had to donate a daughter to the war effort. Many others were offered food, shelter and factory jobs. The Japanese also kidnapped young, unmarried girls when they had a shortage of comfort women. The ages of the girls in the comfort houses ranged from 15 to 19, with the minority exception of some younger girls and some older, married women. The girls were transported between military bases like cargo, under heavy guard in army trucks, trains, ship and bus. They were forced to lose their virginity before arriving at the bases to prepare them for having sexual intercourse with tens of soldiers every day. Many women contemplated death after this, as they believed their virginity to be more precious than life. (Henson) When living in the comfort houses, the comfort women lived in fear and desperation. They were unable to leave, as they were heavily guarded. Each day, they were penetrated by as many as 50 soldiers, until they were sore and bloated to the point of not being able to open their legs. If they were infected with a sexually transmitted disease, they received injections known as Injection 606. If infected enough times, they lost their fertility. In Japan, infected women were killed. Their food was mixed with cyanide, their bodies taken to a cave and finally, the cave was blown up with a grenade. The comfort houses made money off these women and it is believed that the Japanese government paid them, as most of the soldiers paid by coupons. As soon as the war was finished, the Japanese Imperialist guards disappeared without trace. Most comfort women describe the experience this way, † Suddenly, the soldiers came no more, and upon asking we found that the war had ended. † In other regions, as the Japanese committed â€Å"harikari†, the women were forced to do the same. In extreme cases, the women were put in a cave and blown up. After the war, many of the comfort women were too sick to be moved and were taken under the care of the American army. Most of the women were left with no place to go, as they were in a strange country with no money, and were too humiliated to go home. According to one comfort woman, † my body’s wasted, therefore I do not dare go home in fear of being ignored and looked down upon. † Even after the war ended, the comfort women were not free. Their guilty minds and inferiority complexes kept them from returning home and they stayed in foreign countries. The small amount that married, were often forced to separate after the fact that they were comfort women was known, or they were divorced because they could not have children. The victims are still suffering the pain physically and psychologically. More than half of them could not get pregnant, and most of them have chronicle diseases. Furthermore, the psychological impact on these women made them felt themselves dirty, ashamed that they disgraced themselves and isolated themselves from others. They are either afraid of getting married, or unable to ask for any commitment from their lovers. For those who got married, their marriage was unstable and unhappy due to their past. Some thought that they must have done something evil in their previous life that they have to be punished in this life. (Hicks) They go to tempos to chant sutras, to confess, to pursue liberation, and they even commit suicide. Although the period of time they spent at the Japanese military base was a small part of their life, what they had experienced caused an incurable impact on their health, marriage, mind, and social adaptation. Although the Japanese government continues to deny or minimize their involvement with comfort women, their defense is unraveling. A conference on â€Å"Japanese Crimes Against Humanity: Sexual Slavery and Forced Labor† was held last year, in which Japanese researchers delivered papers which claimed that the Japanese military, the rest of the government, and Japanese industry were all involved in the decision to provide sex slaves for the country’s soldiers. (Chunghee) Japanese historian Hirofumi Hayashi said: â€Å"The establishment and development of the military ‘comfort women’ system†¦ as not only carried out by the total involvement of every section of the military but also by administrative machinery at every level of the Japanese state†¦ In addition, we should not overlook that Japanese companies were their accomplices. † (Chunghee) Researchers from the Center for Research and Documentation of Japan’s War Responsibilities in Yo kohama showed that Japanese rubber companies were under government contract to supply 20 million condoms a year to armed forces once the decision had been made to provide sex slaves to the soldiers. Rumiko Nishino wrote that â€Å"high-ranking adjutants† commissioned by Cabinet and sub-Cabinet-level government officials implemented the distribution of the condoms. The availability of condoms to the general population became â€Å"almost nil. † (Chunghee) Last year, the Japanese appeals court overturned an earlier ruling that orders the government to compensate women who were forced to serve as sex slaves during World War II. Both sides had appealed that ruling. The plaintiffs because they thought the compensation was too small, and the government because they refused to pay. Duke) In deciding in favor of the government, the Hiroshima High Court said abducting women to use them as forced laborers and sex slaves was not a serious constitutional violation. Tokyo has admitted that its wartime army had set up brothels, and forced thousands of Koreans, Filipinos, Dutch and Chinese to serve as prostitutes, but it has refused to compensate these victims. Historians say as many as 200,000 women were forced into sexual slavery during World War II.

Celebrity Exploitation

No to Celebrity Exploitation Celebrities have been the eye-candy for mostly all walks of life. Many look up to celebrities whether it’s because of their beauty, talent, and or their accomplishments in life. Because of those reasons, celebrity culture has become one of our national obsessions. We feel the need to know every single thing that happens with all the famous stars, and have no problem invading their personal space. The paparazzi make celebrities feel like they’re a moving target – even when they’re not in public. They shouldn’t need to feel like that.Celebrities should be entitled to live without paparazzi exploitation, because at the end of the day, being a celebrity is just a job. They are people, too, and they are not entitled to entertain us with their private lives. There are many celebrities who have their privacy breached, and one of the recent celebrities to be exploited would be Kate Middleton. The Duchess of Cambridge has always been in the spotlight from the very beginning: to every event she has attended, her wedding, and now, her honeymoon – which was supposed to be personal.Tabloids everywhere published bottomless pictures of Kate Middleton, while she was on her second honeymoon with her husband. I feel the paparazzi have gone TOO far, with breaching one’s privacy. Is it really necessary to take pictures of people naked (yes, celebrities are people, too), without their consent? Kate Middleton has always been a huge role model for many people around the world, and to have the paparazzi try to degrade her image by exposing her personal body parts to the world is not right. Yes, she’s royalty, but she’s still human.I doubt any of you would like to have pictures of you naked leak out all over the internet without your permission. Before the bottomless scandal of Kate Middleton, there was another celebrity, which in my opinion, shouldn’t have been harassed the way she has g otten for her actions. Kristen Stewart, a very well-known actress, who have mostly gotten her fame from being the lead actress in â€Å"The Twilight Series†, had been heavily criticized by society, because she slept with her director – who is married and has children.But for crying out loud, Kristen is how old? 22? Her brain isn’t even fully developed yet, since the human brain fully matures at 25, according to a National Institutes of Health study. Jodie Foster, a well-known actress wrote a critique of Kristen Stewart, defending her. She wrote that, yes, celebrities get huge salaries, but that doesn’t mean that the media has a right to invade their privacy, and destroy someone’s sense of self. Kristen doesn’t deserve all the crap she’s been getting – at the end of the day, she’s only human.All of us make mistakes. So many people have affairs and they’re not being bashed on, what makes Kristen different? Creating tabloids about her mistakes isn’t helping with her well-being, and that’s why so many young celebrities turn out to be ill and do other reckless things. Many young celebrities have been consumed by the media’s judgement, and end up drowning themselves in drugs, sex, and parties to try and get away from it all. A perfect example would be Lindsay Lohan.Lindsay started her career at the age of 3, and now, she is currently 26 years old. Being 26, she has already been arrested several times for reckless driving and possession of drugs. Not to mention, her wild party lifestyle at the clubs. Now, she’s looked down upon many, after each and every mistake she has done. The paparazzi is partly to blame for trying to constantly expose these celebrities and their mistakes, feeling as if they are a moving target, being judge constantly by society to fit a certain standard just because they’re famous.The last celebrity, in my opinion, who is a great example of g etting over-exploited by paparazzi, was Princess Diana. Princess Diana was killed in a car crash, while trying to get away from paparazzi. This is a perfect example of a celebrity who has been harassed by paparazzi to a point of death, just because they wanted to get the new scoop of her and her lover, Dodi Fayed. I don’t think famous people should have to struggle being constantly harassed by paparazzi.It’s hard enough having to fit everyone’s standards of being a celebrity in public -good fashion, pretty face and body, and personality. They shouldn’t feel the need to fit that persona when they’re not in public. In conclusion, celebrities are normal people, too. They shouldn’t get criticized by media if they have been caught by the paparazzi doing things that may be considered scandalous. I’m pretty sure many people do what celebrities do in their private life, in their everyday lives.Yes, celebrities make more money and are generall y far more interesting than normal people, but sometimes, a little too much attention from the media can affect their personal lives. Being a celebrity is a job. And just like any other job, there’s a time and place just to have your personal time. Paparazzi can take pictures of celebrities when they’re in public, but please, they shouldn’t go so far as to invading one’s private life just to gain money. Just try putting yourself in these famous people’s shoes – I bet you wouldn’t want your personal lives be exploited, am I right?

Heart Of Darkness By Conrad essays

Heart Of Darkness By Conrad essays In the novella Heart if Darkness by Joseph Conrad Marlow and Kurtz undergo similar journeys through the most evil and dark regions of their psyche; however, Marlow is able to realize the darkness inside him and retain his soul before he reverts to a savage animal-like Kurtz has. Marlows disillusionment begins as he arrives on the shore of Africa. When he first arrives on the coast of Africa he sees a large warship bombarding the overgrown forest that has encroached on the beach. This firing is random and is only pointless destruction. He sees the natives, and the people view them as their enemies. Marlow thinks of them as enemies at first, however when he sees them up close he thinks they are nothing more than "black shadows of disease and starvation." Marlow sees the natives clinging to the shade which seems cooler and peaceful but when he enters the shade he realizes it is actually "a gloomy circle of some inferno." Marlow identifies with Kurtz finding many of the same qualities that Kurtz has in himself. Marlow idolizes Kurtz. Marlow sees a freeness and rebellious quality he wishes he could possess. Marlow sees that Kurtz has embraced his savage side when he goes and travels with the native savages. Marlow shows he has the savage qualities as well when he follows Kurtz into the forest, but not to the extreme Kurtz has. Marlow also shows his savageness when he is first in Africa when he and his men are carrying a dead man. One of his men expects to see Marlow kill someone, this man sees that Marlow has the potential to kill a man. Marlow realizes that Kurtz is a savage by his actions and behavior. First Marlow is horrified by the human heads on the poles outside his house. Marlow is also outraged and upset when Kurtz threatened to kill him if he did not give him the ivory. Kurtz is willing to kill over a small amount of ivory. Kurtzs viciousness is shown when he threatens him; because Kurtz does no...

Symbiotic Ants and Aphids Have a Strong Relationship

Symbiotic Ants and Aphids Have a Strong Relationship Ants and aphids share a well-documented symbiotic relationship, which means they both benefit mutually from their working relationship. Aphids produce a sugary food for the ants, in exchange, ants care for and protect the aphids from predators and parasites. Aphids Produce a Sugary Meal Aphids are also known as plant lice, they are very small sap-sucking insects that collect the sugar-rich fluids from host plants. Aphids are also the bane of farmers the whole world over. Aphids are known crop destroyers. The aphids must consume large quantities of a plant to gain adequate nutrition. The aphids then excrete equally large quantities of waste, called honeydew, which in turn becomes a sugar-rich meal for ants. Ants Turn Into Dairy Farmers As most people know, where there is sugar, there is bound to be ants. Some ants are so hungry for the aphid honeydew, that they will milk the aphids to make them excrete the sugary substance. The ants stroke the aphids with their antennae, stimulating them to release the honeydew. Some aphid species have lost the ability to excrete waste  on their own and depend entirely on caretaker ants to milk them. Aphids in an Ants Care Aphid-herding ants make sure aphids stay well-fed and safe. When the host plant is depleted of nutrients, the ants carry their aphids to a new food source. If predatory insects or parasites attempt to harm the aphids, the ants will defend them aggressively. Some ants even go so far as to destroy the eggs of known aphid predators like ladybugs. Some species of ants continue to care for aphids during winter. The ants carry the aphid eggs to their nests for the winter months. They store the precious aphids where temperatures and humidity are optimal, and move them as needed when conditions in the nest change. In spring, when the aphids hatch, the ants carry them to a host plant to feed. A well-documented example of the extraordinary mutualistic relationship of a corn root aphid, from the species Aphis middletonii,  and their caretaker cornfield ants,  Lasius. Corn root aphids, as their name suggests, live and feed on the roots of corn plants. At the end of the growing season, the aphids deposit eggs in the soil where the corn plants have withered. The cornfield ants collect the aphid eggs and store them for the winter. Smartweed is a fast-growing weed that can grow in the spring in the cornfields. Cornfield ants carry the newly hatched aphids to the field and deposit them on the temporary host smartweed plants so they can begin feeding. Once the corn plants are growing, the ants move their honeydew-producing partners to the corn plants, their preferred host plant. Ants Enslave Aphids While it appears the ants are generous caretakers of aphids, ants are more concerned about maintaining their steady honeydew source than anything else. Aphids are almost always wingless, but certain environmental conditions will trigger them to develop wings. If the aphid population becomes too dense, or food sources decline, aphids can grow wings to fly to a new location. Ants, however, do not look favorably upon losing their food source. Ants can prevent aphids from dispersing. Ants have been observed tearing the wings from aphids before they can become airborne. Also, a recent study has shown that ants can use semiochemicals to stop the aphids from developing wings and to impede their ability to walk away.

Evolution Assignment Example | Topics and Well Written Essays - 500 words

Evolution - Assignment Example At the outset, evolution being a prominent theory of science and is fundamentally and entirely based on physical and empirical evidences, which may be fossils and bacteria. Whereas, the Bible or as it is more commonly known â€Å"the word of god† is not at all backed by any evidence whether it be empirical, observational, or practical, let alone physical. The belief of Christians in Bible is solely based on â€Å"faith†. (Gisburne) The Bible tells us that the earth and all living things on it were â€Å"created† in 3760 BC (according to the Hebrew Calendar), and yet scientists including Darwin have discovered fossils that are millions of years old, which directly contradict the teachings of Bible according to which the fossils of humans, animals or plants could not date back more than 7000 years. (Dosick 119) Another major factor of distinction amongst beliefs is the fact that evolution supports natural selection a concept which considers survival of the fittest to be its sub category. According to the concept of natural selection, as species that were not previously habitable mutate, they supplement features or changes that are more suitable to the environment and after a long period of time, as more and more habitable creatures mate, the feature becomes generic and further evolution takes place until the fittest survive. (Darwin and Carroll 17,19,594) The Bible strongly contradicts this theory considering their own version of the theory, which they refer to as â€Å"the truth†, according to which they state that God created man and humans did not evolve. But if that’s true then the long list of connected fossils and matching DNA that the scientists have found would be wrong, but in reality that is not the case. The DNA of correlated species match significantly to falsify any void claims made solely on â€Å"faith†. (Gisburne) (Darwin and Carroll) Besides, according to their point of view, if man has descended from god, then the scope of mutation does
