A glass of Milk, paid in Full
A glass of Milk, paid in Full One day, a poor boy who was selling goods from door to door to pay his way through school, found he had only one thin dime left, and he was hungry. He decided he would ask for a meal at the next house. However, he lost his nerve when a lovely young woman opened the door.Instead of a meal he asked for a drink of water. She thought he looked hungry so brought him a large glass of milk.He drank it slowly, and then asked, How much do I owe you? You dont owe me anything, she replied. Mother has taught us never to accept pay for a kindness.He said, Then I thank you from my heart.As Howard Kelly left that house, he not only felt stronger physically, but his faith in God and man was strong also. He had been ready to give up and quit.Years later that young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where they called in specialists to study her rare disease.Dr. Howard Kelly was called in for the consultation. When he heard the name of t he town she came from, a strange light filled his eyes. Immediately he rose and went down the hall of the hospital to her room.Dressed in his doctors gown he went in to see her. He recognized her at once. He went back to the consultation room determined to do his best to save her life. From that day he gave special attention to the case.After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the final bill to him for approval. He looked at it, then wrote something on the edge and the bill was sent to her room.She feared to open it, for she was sure it would take the rest of her life to pay for it all. Finally she looked, and something caught her attention on the side of the bill. She began to read the following words:Paid in full with one glass of milk.Signed, Dr. Howard Kelly.Author Unknown

The Way Address Equality And Diversity Towards Their...
The main aim of this research study is to consider opinions and the way address equality and diversity towards their employees within the UK music industry. This proposal suggests that this can be done by two means of methodological research; a literature review and also gathering data from qualitative and quantitative methods. Research will be particularly aimed at all of the most important factors surrounding equality, diversity and the manifestations of discrimination. The UK can be seen as an unequal industry to work in when we talk about inequalities and diversity in the music industry sector. The word diversity stands for the differences in each individual and how they are unique. Differences can be both visual and non visual such as, gender, religion, race, social class, age or mental health. The word equality has a meaning that each individual should be valued, accepted and treated equally regardless. ââ¬ËImagine, for a minute, a workplace where everyone is the same. All of the workers are of the same ethnicity, gender, educational background, and socioeconomic standing. With a team of people essentially cut from the same cloth, where do the new ideas come from? How will the company ever be able to see things form a different point of view?ââ¬â¢ (Research and Markets, 2010:2). Equality and diversity is important for both the individuals and the business.

Analysis Of The Film Citizen Kane By Orson Wells
Intro I have chosen to use an extract from the film ââ¬ËCitizen Kaneââ¬â¢, directed by Orson Wells (1941) for this assignment. The technical aspects I have chosen to explore will be the use of both mise-en-scene and editing. Synopsis The clip I have selected from Citizen Kane is a montage scene that shows the protagonist Charles Foster Kane eating breakfast with his wife Emily. The scene is presented in the form of a narrative exposition from the mind of Jedediiah Leland, who is the ex business partner of Kane. The entirety of the scene is comprised of Kane and his wife conversing with one another whilst eating breakfast. (Scene time code: 49:23-52:42). Analysis The use of elliptical editing in the form of a montage is a dominant force in the make up of my chosen extract. This helps condense large sections of time that comprise of many years into smaller transitions that are more aesthetically pleasing to the audience. ââ¬ËThis simple and basic technique allows narratives to span large spatial and temporal distances without the need to follow dull actionââ¬â¢ (Duckworth, 2008). In this particular scene it is important to note that only time has been manipulated, not space, as the narrative occurs in only one setting for the duration of the scene. A slow dissolve is used as Lelandââ¬â¢s recollection of Kaneââ¬â¢s relationship with his wife takes the viewer to the breakfast table. ââ¬ËThe dissolve is defined as a gradual change from the ending pictures of one shot into the beginning picturesShow MoreRelatedOrson And Citizen Kane, Touch Of Evil, And Othello, Make Him A Great Auteur?

Lgbt Issues Free Essays
LGBT Issues LGBT issues really caught my attention. I was never cared or thought about people are lesbian, gay, bisexual or transgender until I took this class. What really caught my attention was Paulaââ¬â¢s story. We will write a custom essay sample on Lgbt Issues or any similar topic only for you Order Now That was very touching, and I felt bad for her. And I realized that probably many people have most likely gone through what she went through; especially with your family. Your family are the ones who love you and are always suppose to be there for you and when they are not there for you when you really need them at a time like that. In your lecture, on November 17th, you discussed about sexual orientation. Not only is it a sexual attraction but also a spiritual connection, as well as an emotional and romantic attraction. It is not the same as sexual behavior because it deals with feelings and emotions. This ranges on a scale from exclusive homosexuality to exclusive heterosexuality. The scale is called the ââ¬Å"Kinsey Scaleâ⬠from 0-6. Zero meaning heterosexuality and six meaning homosexuality. There has been a struggle for equality for many years. Through gender, race and now sexual orientation. Still to this day there are the struggles of gender and race, such as for African Americans and Women, but it has gotten better. Now the main struggle is for the lesbians, gays, bisexuals and transgender. The struggle for equality, such as marriage. I am now starting to realize that why should a person be judged on whom you are attracted to, or whom you connect with? I know I would not want to be judged that way. Also, if you love someone and you are willing to spend the rest of your life with them and make a family and you are willing to marry them, then go do it. No one should have the right to tell you who to marry. As it says in this article, ââ¬Å"The Semantics of Marriage Equalityâ⬠, written by Steve Kleinedler, he argues, ââ¬Å"When asserting that marriage has always been solely a union between one man and one woman, our adversaries trot out old dictionary definitions to support their claims. The job of dictionaries is primarily to describe how language is used, not to dictate how it should be used. â⬠Still to this day people are fighting for the same sex marriage. A recent article in The New York Times, ââ¬Å"New York State Senate Votes Down Gay Marriage Billâ⬠, written by Jeremy W. Peters. had said that The New York State Senate rejected a bill on this past Wednesday that would have allowed same sex marriages. The vote was 38 to 24. The gay rights organizations have steered almost up to $1 million into the New York legislative races to boost the support for the bill to be passed. He said that the senators who had voted against had explained by saying, ââ¬Å"the public was gripped by economic anxiety and remained uneasy about changing the stateââ¬â¢s definition of marriage. â⬠They believe that the problem is ââ¬Å"deadâ⬠in New York at least until 2011, when a new legislature will be installed. Now reading about all these articles and hearing stories, such as Paulaââ¬â¢s I now feel bad and understand where they are coming from. I may not fully understand since I am not a lesbian or bisexual, but I now have an understanding of what people are going through. I do not have any lesbian, gay, bisexual or transgender friends, so I never understood or really cared about the situation, but now I do. Whenever I found out that someone was gay or lesbian or even bisexual I would honestly stop talking to him or her, I do not know why, but that was my reaction. Now I want to make friends with them, it would not hurt. I am not saying that I am going to go out and try to make friends, but if I do happen to come across and meet someone who is gay or lesbian or ever transgender I would like to give them a chance to be my friend. I think if my parents knew they would not be happy about it, but I think maybe I can make my parents realize that it is okay. They are normal people like anyone else. Spending time with someone does not turn you gay, because some people may feel that way. Like when we had a discussion in class about gay and lesbian parents, and some people had felt if the parents were gay or lesbian that the child sexual orientation would be homosexual as well. Which is not true. It is something inside of you that you cannot control. I honestly believe it is something that you are born with, you just cannot help it. I hear stories about people whom if they could change their sexual orientation and become heterosexual they would, so they would not have to go through the pain that some people put them through. I enjoyed learning this topic in class. At first I was not so pleased that we would be talking about it, but Paulaââ¬â¢s story caught my interest and that is when I decided I wanted to do my paper on LGBT issues.

Social Environment Essays - Aid, Development, Economic Development
Social Environment Social Environment and Its Effect On One's Life Social environment is influenced by one's power and wealth. This, in turn, determines success or failure in peoples' lives. If one were born with a silver spoon in his mouth, he would easily be able to attend a fancy school no matter how intelligent he is or have any luxury he wants just because of power and wealth. On the flip side, if one were born to a poor family in a bad neighborhood infested with violence and drugs, he would have a much smaller chance of succeeding in life, more especially, going to an upper-class school. It is hard for many poor to go to college because of such high tuition costs. Scholarships are available; but, even though one shows financial need, one still has to have a high grade point average and test scores. Even if one has a good mind, trying to study in a gang-ridden neighborhood with constant gunfire isn't easy. With both parents working two jobs, there isn't any parental guidance. Whereas, the affluent, even if busy or working, have the means to insure that their children are supervised and well taken care of. The rich also have the luxury of affording special tutors to help their children while other children are on their own. For example, there are three students, one from a clean, upper-class community, another from a small, middle-class suburb and the other from a graffiti-ridden slum. All three of these students have exceptional GPA's and scored very well on standardized testing. The student from the upper-class community will have the best chance of succeeding. Tuition will never be a problem and chances are that those parents have some pull because of who they are. The middle-class student won't have a great problem but there is still the fact of paying tuition, which would limit the options quite a bit. One may be smart enough to get grants but the family makes too much money. Also, if he sought admission into a prestigious school and it came down to the student or someone richer, the middle-class student would probably lose out. Some of the many reasons for this are that the affluent family will most likely have been an alumni to that particular school. If not, they will have better connections and will have a more impressive letter of recommendation written for the student. However, the lower-class student would have a much rougher time. Even with good grades, he might lack the opportunities that others may have. Tuition is definitely a problem and with an overworked guidance counselor, a problem of a poorer school system, scholarship information might be missing. Most importantly, there would be a decided lack of motivation on the part of the school, family and maybe even the student. I am not saying that social environment is the definitive factor in someone's lifetime accomplishments. It is common knowledge that it is difficult to get out of a bad situation such as growing up without any of the advantages others have, but many have managed. There is a way out, it just takes a strong mind and a strong will to do so. If someone is intelligent enough, they can try to go out and grab the recognition they deserve. Social environment as a determining agent is definitely a human-made force. In society, the poor are regarded with contempt or completely ignored while the rich are seen as having the authority over everything. The poor are seen as undeserving, therefore, not receiving much of an education, if any. In any society, there are always the strong and the weak; and, in this case, the weak are portrayed as the poor by the rest of society. Some feel that the weak in our society should be eliminated because they are no more than mere pests, irritating the rest of society. In my opinion, there isn't much to be done to change the way society thinks. As long as the elite control businesses and schools, they will still have the authority over what the public thinks and does. The best thing to have is a positive outlook on all situations and never stop trying. If one never gives up, one can achieve his goal no matter how unreal it may seem at the time. The most important thing is never to let society get in the way. One must not fall prey to society's evils and give up. If there were to be a solution, it would have to be bringing more

Blister Beetles, Family Meloidae
Blister Beetles, Family Meloidae Few North American species of blister beetles will actually cause blisters, but its still smart to be cautious when handling members of the beetle family Meloidae. Theres some debate over whether blister beetles are pests (because the adults feed on many agricultural crops and can be hazardous to livestock), or beneficial predators (because the larvae ââ¬â¹consume the young of other crop-eating insects, like grasshoppers). Description Blister beetles look superficially similar to members of some other beetle families, such as the soldier beetles and darkling beetles. Blister beetles, however, do have some unique features that will help you identify them. Their elytra appear leathery and soft, rather than rigid, and the forewings wrap around the sides of the beetles abdomen. The blister beetles pronotum is usually cylindrical or rounded, and narrower than both the head and the base of the elytra. Most adult blister beetles are medium in size, although the smallest species measures just a few millimeters in length and the largest can reach 7 centimeters long. Their bodies are generally elongate in shape, and their antennae will be either filiform or monofiliform. While many are dark or drab in color, particularly in the eastern U.S., some do come in bright, aposematic colors. Look for blister beetles on flowers or foliage. Classification Kingdom ââ¬â AnimaliaPhylum ââ¬â ArthropodaClass ââ¬â InsectaOrder ââ¬â ColeopteraFamily - Meloidae Diet Adult blister beetles feed on plants, particularly those in the legume, aster, and nightshade families. Although rarely considered a major crop pest, blister beetles do sometimes form large feeding aggregations in plants. Many blister beetles consume the flowers of their host plants, while some feed on the foliage. Blister beetle larvae have unusual feeding habits. Some species specialize in eating grasshopper eggs, and for this reason, are considered beneficial insects. Other blister beetle larvae eat the larvae and provisions of ground-nesting bees. In these species, the first instar larvae may hitch a ride on an adult bee as it flies back to its nest, and then settle in to eat the bees offspring. Life Cycle Blister beetles undergo complete metamorphosis, like all beetles, but in a somewhat unusual way. The first instar larvae (called triungulins) usually have functional legs, well-developed antennae, and are quite active. These young larvae need to move because they are parasitoids and must find their hosts. Once theyre settled in with their host (such as in a bee nest), each successive stage is typically less active, and the legs gradually diminish or even disappear. This larval development is referred to as hypermetamorphosis. The final instar is a pseudopupa stage, during which the beetle will overwinter. Depending on the species and environmental conditions, the blister beetle life cycle may last as long as three years. Most species will complete a full life cycle within one year, however. Special Behaviors and Defenses Blister beetles are usually soft-bodied and may seem vulnerable to predators, but they arent defenseless. Their bodies produce a caustic chemical called cantharidin, which they exude from their leg joints when threatened (a defensive strategy called reflex bleeding). Meloid species with high levels of cantharidin can cause skin blisters when handled, giving these beetles their common name. Cantharidin is an effective repellent for ants and other predators but can be extremely toxic if ingested by people or animals. Horses are particularly susceptible to cantharidin poisoning, which can occur if their hay feed is contaminated with blister beetle remains. Range and Distribution Blister beetles are most diverse in arid or semi-arid regions of the world, though widely distributed. Globally, blister beetle species number close to 4,000. In the U.S. and Canada, there are just over 400 documented blister beetle species. Sources: Borror and DeLongs Introduction to the Study of Insects, 7th edition, by Charles A.

Bacteriophage Life Cycle Animation
Bacteriophage Life Cycle Animation Bacteriophages are viruses that infectââ¬â¹ bacteria. A bacteriophage can have a protein tail attached to the capsid (protein coat that envelopes the genetic material), which is used to infect the host bacteria. All About Viruses Scientists have long sought to uncover the structure and function of viruses. Viruses are unique they have been classified as both living and nonliving at various points in the history of biology. A virus particle, also known as a virion, is essentially a nucleic acid (DNA or RNA) enclosed in a protein shell or coat. Viruses are extremely small, approximately 15 - 25 nanometers in diameter. Virus Replication Viruses are intracellular obligate parasites, which means that they cannot reproduce or express their genes without the help of a living cell. Once a virus has infected a cell, it will use the cells ribosomes, enzymes, and much of the cellular machinery to reproduce. Viral replication produces many progeny that leave the host cell to infect other cells. Bacteriophage Life Cycle A bacteriophage reproduces by one of two types of life cycles. These cycles are the lysogenic life cycle and the lytic life cycle. In the lysogenic cycle, bacteriophages reproduce without killing the host. Genetic recombination occurs between the viral DNA and the bacterial genome as the viral DNA is inserted into the bacterial chromosome. In the lytic life cycle, the virus breaks open or lyses the host cell. This results in the death of the host. Bacteriophage Life Cycle Animation Below are animations of the lytic life cycle of a bacteriophage.Animation AThe bacteriophage attaches to the cell wall of a bacterium.Animation BThe bacteriophage injects its genome into the bacterium.Animation CThis animation shows the replication of the viral genome.Animation DBacteriophages are released by lysis.Animation ESummary of the entire lytic life cycle of a bacteriophage.
