The Night she ran away
The Night she ran away Free Online Research Papers I wish I could say she talked me into it, or even that helping her was her idea. But for some reason, this time, I decided that helping her runaway would be fun. Dee and I had been best friends since we met in sixth grade. We helped each other through the roughest times of our teenage years, and we were partners in crime. It was a beautiful night-cool breeze, clear sky and I was feeling happy and free. We were driving around in my blue eighty-seven Ford LTD. Which I didnt care that it was just as old as I, or that a battery powered boom box had its place in between us on the seat. I picked Dee up from work around ten oclock and we planned our night out. She was supposed to be home by ten thirty, but whats the worst her mom would do? Dee didnt plan on ever going back anyway. I on the other hand, had told my dad I was staying at a friends house around the block, although I planned on sneaking into my room later on that night. We knew a guy who did piercings out of his house in a part of town that we referred to as the hood, and Dee wanted her eyebrow pierced. We saw no problem with this; who else would pierce a fifteen year olds eyebrow without parental consent in the middle of the night? When we arrived, the house was poorly lit and smelled like dust. There was an old couch with a tacky pattern of flowers in one corner and a computer desk with a kitchen chair in front of it in another. Then there was a cart Dee sat in front of to get pierced. I sat on the corner of the couch closest to the door, while Dee waited to get pierced. As he was cleaning and preparing, we were listening to the scanner in the background. The broadcast that came over the scanner said they were looking for two female runaways age fifteen, driving a blue Ford LTD. We denied that they were talking about us. Dee got her eyebrow pierced, threw up from the blood and we got out of there. While we were enjoying our freedom, little did we know that Deeââ¬â¢s mom realized she never came home, so she called my dad to see if she was with me. My dad called my alleged location and I wasnââ¬Ët there. Because Dee had already threatened to run away, the cops were called. They thought we were running away together. Now my gas tank was on empty and I had to get Dee where she was going so I could get home. We stopped at the gas station with only three dollars and headed out of town. Our destination was about thirty minutes away, except ten miles down the highway the three dollars in gas was gone. It wasnââ¬â¢t a busy highway, there was one house around but we got no answer. We decided to flag down the next car we saw to hitch a ride. As soon as I saw the flashing lights, I knew I had made a mistake. At first I panicked and turned to run. After weighing the options, I decided I probably wouldnt get far. The police officer asked our names and immediately knew who we were. He put us in his SUV, me in the back sitting next to his not so cute dog, and Dee in the front. With my palms sweating, my stomach in knots, and my heart pounding, I watched him search my vehicle and waited for the dreaded ride to wherever he was taking us. As he pulled in my driveway, I was slightly relieved yet still scared to face my dad. I walked up the porch stairs with the police officer, my dad waiting for us at the front door. I was crying and waiting to get a scolding. So you can imagine I was surprised as he grinned and said, Welcome home, kiddo, as if he was making fun of me. And then I got grounded for lying about where I was that night. The next night Dee tried to run away again and got locked up in the juvenile detention center. I dont regret the experience because I learned a valuable lesson. No matter how much freedom I had, it was a privilege, and I had to earn it to keep it.

Culture and Family in Nursing Essay Example | Topics and Well Written Essays - 1750 words
Culture and Family in Nursing - Essay Example A vital objective for health care providers, as for instance, is established in the increasing acknowledgment of the family's value to a child's recovery and the influence of child's infirmity on the family. The importance of understanding the impact of culture on family health and nursing is related to a considerate practice of the family, as it establishes a realism that confirms the analysis that professional nursing perform which is crucial to health care. As realization increases on the influence of culture, concern is heightened in improving the efficiency of the involvement, given inconsistencies of cultural diversity, and the survival of children of minority families. (Radin, N., & Goldsmith, R. 1983 p 18) psychological needs for identity and sense of historical continuity. The ethnic background influences our way of thinking, our way of feelings, our way of working, and our way of relaxing, our way of celebrating holidays and customs, our way of expressing our anxieties, our way of belief about illness or life and death. Patterns of ethnicity, strengthened by family custom and community association, can function in delicate ways, normally outside of our consciousness; but their influence may however be extensive, deep and compelling. These patterns are capable to perform a significant responsibility throughout the family life series, though influence may differ among groups and within a group itself. In few families who cling to customary ways, adhering to groups from their spiritual or cultural background and apart from all others, ethnic values and classifications may be predominantly strong and probably to be kept for generations (Pleck 2000 p 48) Gender - a study shows that children at two and a half years of age practice gender classifications in negotiating their humanity and are possible to simplify gender classifications to several of activities, objects, and professions. Children yet refuse the truth of what they are perceiving when it does not correspond to their gender principles, such as the interpretation of a child that only men are doctors, when his or her mother is. Sons have a precise boundary concerning parental choices with regard to children; as majority of parents rather have male than female children, recognized all over the world. In the same manner, people who favor sons are more possible to apply technology for deciding on the sex of their child. This inclination for male children, furthermore, is accentuated by the ruling that parents are more possibly to maintain having children if they allow only girls than if they allow only boys. Explanations given by women for their choice for sons are to satisfy t heir husbands and to maintain the family name, and to be a companion to the husband. However, the reason for women desiring for daughters is their need for a companion for themselves and to have fun dressing a girl and doing her hair. 3 Parents influence their sons and daughters to get involve in sex-typed endeavors, as well as doll playing and managing housekeeping endeavors for girls and playing with trucks and participating in

Leprosy in the Middle Ages Essay Example | Topics and Well Written Essays - 1000 words
Leprosy in the Middle Ages - Essay Example This essay focuses on the discussion of the Leprosy, or Hansenââ¬â¢s disease, that is an debilitating disease which has been prevalent for over 4,000 years, right from the ancient civilizations of China, India and Egypt. The researcher states that the earliest documented case of leprosy, supported by DNA evidence, is that of a man whose remains were discovered in a tomb next to the Old City of Jerusalem. The first recorded instance of leprosy is found in the Bible. It is probable that the disease spread to Europe from Egypt through Phoenician sailors in the 8th century. The word leprosy has its roots in the Greek lepra, meaning ââ¬Ëa disease which makes the skin scaly'. The primary external symptom is pronounced skin lesions. It is caused by the bacteria Mycobacterium leprae. If unchecked, this chronic bacterial infection can progressively attack the skin, nerves, limbs and eyes, causing permanent damage, deformation, blindness, loss of neural sensation, and local paralysis. Th e mode of transmission of the disease is still not certain. Poor living conditions, diet and genetic factors may predispose an individual to contact leprosy. Treatment for leprosy began with the introduction of dapsone in the 1930s and complete cures were made possible by multidrug therapy in the 1980s. It is acknowledged that leprosy was a familiar disease in medieval Europe, and probably reached its peak during the twelfth and thirteenth centuries. In the Middle Ages, leprosy was a serious problem which elicited unique social and medical responses. ... In the Middle Ages, leprosy was a serious problem which elicited unique social and medical responses. Leprosy was a feared condition throughout the Middle Ages. This may be largely attributed to ignorance of its causes and medical implications, and the absence of any recognized treatment or cure. The Medieval diagnosis of leprosy, ââ¬Å"was a prediction of disfigurement and death, and what is perhaps more terrifying, it separated a man from society because of the infection he carried outwardly and the moral corruption that lay within himâ⬠(Covey, 2001, 316). Biblical references supported this reaction to the disease. The numerous references to leprosy in the Bible largely give leprosy a connotation of being a disease of the unclean. This is evident in the passage from Leviticus 13: 44ââ¬â46 which states, ââ¬Å"Now whosoever shall be defiled with the leprosy, and is separated by the judgment of the priest, shall have his clothes hanging loose, his head bare, his mouth cove red with a cloth, and he shall cry out that he is defiled and unclean. All the time that he is infected and unclean, he shall dwell alone without the campâ⬠(Covey, 2001, 316). In effect, the Bible condemned leprosy as a ââ¬Ëdefilementââ¬â¢ and sanctioned the banishment of lepers from society. The most common attitude toward leprosy was ostracism, rising from the fear that leprosy was a highly contagious disease. In the light of this fear of contacting leprosy through association with lepers, medieval laws enforced segregation of lepers in various manners in different places. The 1276 assizes of London restricted the freedom of movement of lepers by banning them from residing in the city. This was followed by

The American Indian and the Problem of Culture Essay Example for Free
The American Indian and the Problem of Culture Essay The Native Americans are perhaps the most culturally storied and richly diversified culture in the America. Indeed, the historical narrations of the Indian culture, way of life and lifestyle are narrated as rich in strife, struggle as well as triumph. In fact, a majority of the modern ways of life and lifestyle in the United States are directly or indirectly inherited or borrowed from the ancient Indian cultures of centuries ago. Yet, most Americans take for granted the many familiar symbols that trace their origin from the Native Indian Americans. The purpose of this paper is to describe the culture of the American Indians. The American Indians used various symbols that interwove the tapestry of their lifestyle. Integral symbols such as the totem pole, the teepee, the moccasins and the peace pipe formed a special cultural trait of the American Indians life (Barrett, 2004). Native animals and plants as houses and weather had a special cultural relationship with the American Indians. For instance, the American Indians revered animals for spiritual believes and ties in spite of their hunting practices. Animal hides and skins made drums and clothes while the meat was preserved and never wasted to nourish the community. The American Indians believed that the spirit of the animals killed lived through the community by inhabiting the tribeââ¬â¢s minds. The American Indians cultivated and later harvested various plants for different reasons and seasons such as making blankets and dyes (Biolsi Martin, 1989). Weather elements bore cultural meanings, attachments and endearments to the community, as well. For instance, the American Indians believed that the sun and the rain were supernatural powers and represented a change in the Indianââ¬â¢s seasons. Totem poles formed a special part of the America Indianââ¬â¢s culture (Hallowell, 1957). For instance, they believed that every personââ¬â¢s spirit in the community was attached to particular animalââ¬â¢s spirit. Therefore, the community believed that, at death, a personââ¬â¢s spirit was absorbed by his or her attached animal to live on or regenerate as another person at birth. As a tall and large wooden carving, the totem pole was framed to represent various animals with a certain animal representing a cherished but deceased member of the family. Today, it is easy to observe a dangling dream catcher hanged from rearview mirrors on cars driving in the United Statesââ¬â¢ roads. However, people rarely know or acknowledge the significance of the dream catchers. Indeed, this symbol traces back to the Lakota tribeââ¬â¢s legendary stories (Hallowell, 1957). It is a symbol of holding onto dearest things in a personââ¬â¢s life. In addition, the perforated holes in a dream catcher serve to filter ill feelings and thoughts. Another Interesting aspect of the American Indianââ¬â¢s culture is smoke signaling. The American Indians used smoke signals to send and relay messages over long distances and bore a proud heritage amongst the American Indians. The American Indians also believed in spirits and depended on them for the well being and nourishment of the society (Barrett, 2004). Spirits were tied to various outcomes in the society such as bumper harvest, natural disasters and tragedies and community health. As a result, the spirits were kept pleased to see to the survival and good harvest in the tribe. Sacrifices and offerings were made at sacred places to the spirits. For instance, the Pueblo tribes regarded various plants as sacred while the Aztecs offered human sacrifices to appease the spirits. References Barrett, C. A. (2004). American Indian culture.

Why Americas Capitalist System Is Failing Essay -- Capitalism Failure
Why America's Capitalist System Is Failing à à à à à The American capitalist system works in a way that enables a small percentage of the population to live in utmost comfort with a large percentage of the countryââ¬â¢s money and power. The majority of them get to this position through affiliation, and the lesser of them contrastingly through many years of hard work and struggle through a system that forces assimilation prior to incorporation. The majority of the population either lingers in the middle-class working for big businesses, whose ethical role in society they have no say in, or own a business that puts the responsibility of the lives of several shareholders in their hands. The remainder of society lives off of these people; cleaning, cooking, or serving for them. The only difference between this economic system and the old caste system in India is that the Americans can move between castes only by denying their moral beliefs. à à à à à Take, for example, the current president George Bush; his business skills did not permit his original business endeavors to succeed. He was actually a drunken party-boy, until the expectations to live up to his family name pressed him to seek success. Despite his disqualifications, the Bush name enabled him to overcome his bad investments and eventually receive a well-paying office job that required little of him. In contrast to a man that came from a less-renowned family, this young manââ¬â¢s lack of characteristics that generally evoke succe...

The AKA language was protected from outside influence Essay
The writer started his article by describing a group of people called Tuvans, who lives in a remote area in the Republic of Tuva, in Russian Federation. The importance of this group came from the fact that they are speaking Tuvan, a language consider by linguists to be among a group of languages that are considered to be on the edge of extinction because of the low numbers of people that speak it. The earth population speak approximately 7000 languages. Tuvan is among the 3500 small languages that are spoken only by 8. 25 million people in the entire world, which is a very low fraction of the seven billion people who inhabit the earth. On the other hand, seventy eight percent of the earth population are speaking only 85 languages, Mandarin, Spanish, and English are among the top spoken languages on the globe. Linguist predicted that in the next century almost half of the spoken languages may vanish, and at this point more than 1000 languages are considered on the extinction. The writer mentioned the reasons that lead to this languages dilemma. He mentioned the effect of the dominant languages, that controls communications and commerce, on the small one that do not have any defense mechanism, like television or currency, to protect its existence. Because of that the people of Tuva must speak Russian or Chinese if they want to stay in contact with the outside world. The writer then mentioned another endangered languages known as AKA, the native language of AKA people in Plaizi a small village in India. The writer describe its people as a very self-dependent people that produce everything they need in their daily life. The AKA language was protected from outside influence because of the location of the village that makes it very difficult for outsiders to reach it. The authors then described two trends in the field of linguistics. The first one is based on the theory of Noam Chomsky who mentioned that all languages came from one single origin which is fixed in the human genes. The second trend is the increase interest in small endangered languages around the world, and how the field linguists are interested in idiosyncrasies that distinguish each language from the others and the cultural effects on it. There are 85 percent of the needs to be documented in order to understand it, and the main reason for this documentation comes from the fact that each language contains unique human experiences that reveals many aspects of life . The writer declared very important point regarding the loss of any language. His main idea was based on the fact that every language contains a valuable information about the culture and the knowledge that accumulated from generation to generation in this culture. The author gave us another example of vanishing languages which is the Cmiique Itiom, a language used by the Seri in Mexico and how their language contains the knowledge that is important for all humans. Cmiique Itiom managed to preserved its original form without any outside interference . The Seri managed to keep their language untouched mainly because their hostility to the outsiders. Even the modern commodities likes cars the Seri managed to bring it to their culture but they used for it a unique names that merged from their own language so they never used there Spanish names. The writer mentioned a way to preserved the vanishing languages which is to: ââ¬Å"â⬠¦ enshrine it in writing and compile a dictionary. â⬠. He gave an examples for linguists that worked in those kind of projects like David Harrison and Greg Anderson who compiled the first Tuvan- English dictionary. Also, Steve and Cathay Marlett who worked to finish Cmiique Itiom dictionary, but the writer mentioned very important point which is stated in page 86 : ââ¬Å"But saving a language is not something linguists can accomplish, because salvation must come from within. â⬠. The salvation must come from the people who are using this language by teaching it to the next generation, and also by using dictionaries and books to preserve it and keeping it active as long there is something to speak about it. Writer Choices The writer starts his article by using a story as a hook for the readers, to grab their attention for the rest of the article, and he kept telling the readers different stories about the people he met during his travel. The writer also used creative language ,like figurative language which includes metaphor in many places in the article, and he also used compare and contrast in many other places . Numbers was used by the writers to support his main idea, he mentioned a specific numbers related to the languages in the first page. Visuals aid had been used by the writer to illustrate the subject of his article in a very professional way, yet it was very simple and effective, we can see that from the beautiful pictures for all the people that he met during his trip. Reflection on the Reading Process I found the article hard to read at the beginning, but after using SQ4R and reading the article in class for many times it became much easier for me to understand, and this make the whole process of reading very interesting. The language used not always clear, with difficult word as shown below: Nomadic: roaming about from place to place aimlessly, frequently, or without a fixed pattern of movement. Proselytize: to try to persuade people to join a religion, cause, or group. Dwindle: to gradually become smaller. Thatch: to make (a roof) with dried plant material (called thatch). Supplant: to supersede (another) especially by force or treachery. Atelier: a room where an artist works. Propitious: likely to have or produce good results. Reading process included: Skimming and Skamming ,summarize the article and annotate the key points in it, and SQ4R. Reaction Languages is the soul of human civilizations. The connection between the two of them is very similar to the relationship between human soul and body because without the sole the body will surely collapse because humans need their soul to drive the physical body and to keep him from perishing. In contrast, language plays the same role in people collective awareness about their on existence in the society and culture. Language is the invisible glue that hold the culture pieces together, and without this glue everything will collapse. Itââ¬â¢s the strong foundation that up hold the society structures and grant it the strength to resist any outside threats. Why the language is so important? Because itââ¬â¢s the memory of the society. This memory is the experiences and knowledge that transferred from generation to generation until it reached this point in time, and no it will very hard to live without our memories. Losing any language would be similar to someone who lost his own memory. The only thing he can do is to embrace a new experiences and knowledge, and to start accumulating new memories about his new life. Unfortunately, it is the same thing for languages, when the people abandon their own language in favor for new ones they will lose their cultural experiences and knowledge. They will eventually lose their own identity that distinguished them from the rest of humans. Finally, losing any language on earth would be a lost for humanity in general because we will lose our diversity that make life on earth interesting . I think life with one color would be very tedious, and for life to be interesting it should contain whole spectrum of color. Spinoff Topics One of the spinoff topics would be a to study the individuals that abandon their own language and how they adopt with their new languages and cultures.

Mahou Factory
Mahou Factory Visit Mahou is a Spanish brewery house founded in the year 1890, in the capital Madrid. The company created a reputation for it self that precedes it even now a days, for its quality of production and the traditionalism of the production. Today the company is among the largest and most powerful brewery in Spain with a dominant market share. The main brewery factory, being the one we visited, is located in the outskirts of Madrid, Alovera Guadalajara to be more specific. The Factory is the biggest in Spain and second biggest in Europe, it is unique in Europe for its complex automatized process and innovative technology.The factory produces up to 4 million liters of beer a DAY. Trough out our visit we could observe the process of production of the beer, most being completely automatized, yet having key workers in key locations were mistakes cannot occur. Even the most efficient machines can make mistakes, the problem is that the problem wont be spotted it since its and au tomatized process therefore you need the scientist and key workers in place to reassure the smoothness of the process. This could be considered a poki oki in Japanese terms or a security measure for the avoidance of problems in the production process.From the beginning we could observe a complex system practically runed by computers, the only un automatized process is the lab and examination of samples. But in order to keep control of quality, itââ¬â¢s a process that need to be done with detail and personal, to keep better control of quality even if the cost for it might be high. This with the large control room constantly observing and controlling the brewing process day and night, 24/7, 365 days a year, make it a supper efficient machine for quality control and cost control.The control room has constant machines and computers controlling the brewing process from start to end including the bottling and packaging, This is then combines with a couple of professionals constantly ex amining and managing the process of production with constant control like sample taking to ensure that the quality and process is going to perfection. With this, we can surely say we are of to a good start. Continuing on with the quality control process we then have again several controls to ensure quality, like exporting the water from the erfect mineralization from Guadalajara, like exporting the main resources needed to ensure that their customer gets the quality expected always. After the brewing process there are several other controls like the bottle revision that ensures that they are clean, then thereââ¬â¢s another machine ensuring that they all have the perfect measurements (full) with a laser measurer, after wards a few samples are taken from the produced batch of the day to again lastly ensure that the quality is the desired one.Furthermore we can also observe the cost efficiency process in place. Even though the machinery implemented is expensive in the long term it c uts cost by huge amounts ensuring less mistakes higher quality and happier customers. The control room cuts cost by having many less workers doing the control process over the brewing production process by having it all automatized, not counting how more efficient it is.Then they cut cost by implementing this brewing tanks outside the factory were its easier to obtain the liquid in bigger quantities. But, by a long shot the most efficient cost cutting control is the logistics the factory built right next to the high way to have a quick and easy way to transport and move things. Also they have deals with multiple other breweries to bottle their bear were they do not have a factory in order to make it seemingly less costly and easier to distribute their product.Lastly, I will talk about their green impact on the world, or ecological controls. Now days every company is striving to be a leader as social responsible and environmentally friendly. Every company ahs its motives for this, so me marketing technique, others tax benefits or company reputation etc. Whatââ¬â¢s very admirable of Mahouââ¬â¢s environmental help to the world is that it not only gives good company reputation, tax, etc, its that it is cost reducing also making it cost efficient.Mahous recycles 90 % or more in some cases, of their bottles and containers, due to a deal established with the distributor and maker of the beer containers. This is extremely efficient and green for the environment counting the huge amount of production and trash they are avoiding creating. With both eh process distinguishing the broken or defect bottles and the un-cleanable they have created a perfect quality, cost and environmental friendly control all in one, keeping to its name and reputation.

Drosophila Melanogaster Research Paper Example
Drosophila Melanogaster Research Paper Example Drosophila Melanogaster Paper Drosophila Melanogaster Paper Drosophila melanomas are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled, they have a short life cycle and they are easy to keep large numbers such as the confined spaces of a laboratory or classroom. 1] Drosophila also have a small umber of chromosomes: three autocross pairs and X/Y chromosomes. This helps to simplify genetic mapping and study. The egg off Drosophila is around half of a millimeter long and will take one day from fertilization for the embryo to develop and hatch into Its larvae form. The larvae go through three stages, or instars, before entering the papal stage. This all takes place In roughly six days. Once the Drosophila has entered Its papal stage, It will undergo changes to transform into the adult form and shed Its papal case. The newly emerged adult will be fertile within twelve hours. Of course, temperature does effect the maturation and life cycle of Drosophila. The stated timing of maturation is for a temperature of ICC: at 1 ICC development can take twice as long. [2] In Drosophila, reproduction occurs rapidly. A single pair of fertile Drosophila can produce hundreds of offspring in just a couple of weeks and these offspring, like their parents, will be ready to mate within a week. Drosophila have three main body segments and three pairs of segmented legs. In its adult form the Drosophila has a rounded head with large, red, compound eyes and three mailer simple eyes; this is characteristic of wild type males and females. The female is slightly larger than the male. Males can be identified easily because they have a greater concentration of black pigmentation at the posterior end of the abdomen and they have sex combs on their forelegs. [4] According to an experiment In 1911 by Frank Eugene Lutz, the sex combs seem to have very little to do with sexual selection. [7] Mutations investigated in the class experiment are as follows: patterns , vestigial, bar-eye, and white eye. Crosses were made between virgin wild type males ND virgin females that had homozygous mutant alleles for each mutation, separately. These results were presented to the class as the Fl generation. The class experiment began by separating each of the mutations and phenotypes the results. The patterns mutation was easy to analyze, due to the apparent conditions of the mutation. Patterns mutations in Drosophila melanomas give rise to aberrant, or missing, wings. Another mutation affecting wing formation was the vestigial mutation. By definition, vestigial describes a loss of function. This is precisely how the ins of a Drosophila Is affected when the vestigial mutation Is presented. The wing becomes shriveled or otherwise deformed, and Is no longer functional. [9] The white- eye mutation Is also very easy to Identify. As the name of the mutation Itself states, these flies have white eyes, and are easily distinguished from their red-eyed counterparts Humanly, ten oar-eye mutation Is one In wanly ten eye appears misshapen. This characteristic can be difficult to distinguish from the wild type. In some cases, the red portion of the eye will appear as a narrow slit, or red bar, thus lending to the name of the mutation itself. In other cases, the eye will appear to be kidney shaped instead of ovular; this can be much more difficult to distinguish from the wild type. The experiment was designed to determine the mode of inheritance for each trait; this is to say whether the trait would be associated with autocross chromosomes or sex chromosomes and if it would be dominant or recessive. Materials and Methods To complete the experiment a population of virgin males and virgin females of each mutation to be tested was obtained. Each mutation being tested would have its own culture tube with a food source at the bottom. The food source can be any umber of things, but for this experiment an instant Drosophila medium was mixed water and a small amount of dry yeast was added. After reproducing, the yeast would serve as a food source. The food source should take up no more than one inch at the bottom of the culture tube. A separate culture tube should be used as a sleep chamber to anesthetize Drosophila before characterizing the phenotypes. 4] For each mutation investigated, a culture tube was prepared by the instructor and the flies in these containers served as the Fl generation, the result of parental crossing of wild type males and mutant females. The first step was to anesthetize the Drosophila so they could be counted and sorted by phenotype. Drosophila can easily be anesthetized and manipulated with unsophisticated equipment. In the case of this particular experiment the substance provided to anesthetize the Drosophila with was called Flyway. Flyway consists of a mixture of: 50% Trampoline, 25% Ethanol, and 25% Fragrances. 6] The flies were transferred from the food chamber to the sleep chamber. Once in the sleep chamber, a foam stopper was placed in the tube and a swab dipped in Flyway was inserted into the container. After roughly 60-90 seconds, the flies were fully anesthetized. Once anesthetized, the flies were carefully poured onto a white index card and divided into four categories: male (0*) wild type, male (0*) mutant, female (4) wild type, and female (4) mutant. A soft, fine- tipped paint brush was used to separate the flies into the appropriate categories to avoid any damage to the specimen. As stated previously, males can be distinguished from females because of a few different characteristics: females are slightly larger than males, having seven bands on the posterior end of their abdomens and males eave a dark pigment concentration on their posterior end; males can also be identified by sex-combs on their forelegs. After separating, five males and ten females were placed into new culture tubes, containing a food source. The selection of males and females, as instructed, included both wild type and mutants (if any were present). This was repeated for each mutation and the tubes were labeled and stored for two weeks. At the end of the two week period, it was discovered that the IF generation had not emerged from the papal casing, probably due to a low room temperature. A count of flies present in each culture tube was obtained by beating the aforementioned method of anesthesia and it was concluded that the adult Drosophila present were from the parent [Fl] generation. At this point, the culture tunes contacting ten true IF generation were stores once again Tort a week. The adults had emerged at the end of the final week and were anesthetized, separated, and counted- all through the same procedure as the Fl generation. Results Phenotypes found in theoretical crosses, made between wild type male and homozygous mutant female, for mode of inheritance are as follows: Autocross recessive traits are presented as 100% wild type in the Fl generation and as 75% wild hype and 25% mutant characteristics in the IF generation. Autocross dominant traits appear as 100% mutant characteristics in the Fl generation and as 25% wild type and 75% mutant characteristics in the IF generation. Sex-linked traits are divided between males and females. For sex-linked recessive traits, 100% of females show wild-type characteristics and 100% of males show mutant characteristics in the Fl generation. In the IF generation, 50% of females appear to be wild type and the other 50% are mutants. Males in the IF generation have the same break down. Sex-linked dominant traits are different from their recessive counterparts. In the Fl generation 100% of both sexes show mutant characteristics. 100% of females in the IF generation display mutant characteristics, while 50% of males show wild type and the other 50% show mutant characteristics. Pick] Conclusion The completed experiment leads me to conclude that the patterns and vestigial mutations are autocross recessive traits, the bar-eye mutation is a sex-linked dominant trait, and the white eye mutation is a sex linked recessive trait. After comparing the theoretical cross for autocross recessive traits to the actual results of the crosse s for the patterns mutation and the vestigial mutation, it is easy to see a relation. As expected of a recessive trait, the Fl generation did not show a significant number of mutations, because recessive traits are masked by dominant traits. Though not exact, the phenotype percentages produced from each experimental cross were similar to those produced in the theoretical cross for autocross recessive traits.. There seemed to be a few complications that skewed the results for both the bar-eye and the white eye mutations. From personal experience with difficulty, I believe this could be due to a number of factors. First, consider the bar-eye mutation; the bar-eye mutation presents itself in two ways, as a arrow red slit in the eye when its presence is homozygous and as a red kidney shape when heterozygous for the gene. This is to say that males will always be either wild type or have the extreme version of the bar-eye mutation: the narrow, red slit. Females, on the other hand can present any of three characteristics associated with this mutation. They may appear as wild type or with the extreme version of the mutation Just as the males, but they may also appear to have kidney-shaped eyes. [8] This is, I believe, one main reason the bar-eye results did not line up with any of the theoretical crosses. Another reason for discrepancy may apply to both the bar-eye mutation and the white eye mutation. Being that these are both sex-linked traits, it is Important to properly separate ten sexes when categorizing ten phenotypes. Since our class has had little experience working with Drosophila, it is safe to assume that mistakes were made. Even though the comparison between theoretical results and actual experimental results do not line up for either the bar-eye or white eye mutation I have deduced them to be sex linked because of the way they are presented differently in males and females. The bar-eye mutation was key in making his conclusion, since the differences between the sexes is obvious.

Problems With Chainsaws Made in China
Problems With Chainsaws Made in China Inexpensive chainsaws made in China have drawn great interest in the past few years, including brands such as Blue Max, Zomax, and Showbull. It is easy to find these and other cheaply made chainsaws on various internet sites, but its typically not worth the risk of a bad-performing saw just to save a few dollars. Dont Buy Over the Internet Consumers have reported problems with chainsaws they purchased on the internet. As one buyer noted: I recently purchased a saw on the internet. I have to report that the saw is very poorly made (with) obviously poor quality control. The saw I purchased was not properly packed nor did it come with a manufacturers manual or thorough safety instructions. This consumers experience illustrates the danger of buying any chainsaw on the internet. A few tips for avoiding problems: Never buy a chainsaw without being able to see, touch and inspect it personally.If you buy a chainsaw over the internet, ensure that you receive at least a 30-day warranty.Buy chainsaws from trusted and well-reviewed companies, such asà Husqvarna, Stihl, and Echo, which are all well-made with sturdy parts. These companies have service departments in nearly every community in North America.Buy your chainsaw from a dealer. Most chainsaw dealers will not service saws sold at department stores- or those sold over the internet. So the money you save buying an inexpensive chainsaw will be lost if the saw breaks, unless you are a mechanic and can fix the chainsaw yourself. Youll be hard-pressed to find a shop that will repair these saws. Educate Yourself The problem is not so much in buying a Chinese-made chainsaw; the issue is purchasing any machine sight unseen. If you buy a Chinese chainsaw on the internet, you have no way to verify its quality, generally, are left without a warranty and have little recourse to repair the machine if it breaks. Though some of the Chinese chainsaws may carry respected brand names, they are often produced by any number of subcontracting firms.à Instead, take the time to educate yourself about the parts of a chainsaw, maintenance requirements, what youll be using the chainsaw for and even your level of expertise. If youre a beginner, for example, youll want to look for specific requirements for your first chainsaw. Chainsaw Journal suggests you examine such issues as kickback, bar length, and safety features. You cant carefully review any of these things if you buy your chainsaw over the internet from a company with which you are unfamiliar. Take It for a Test Drive Chainsaw manufacturers are using newer and lighter materials to build more powerful but durable machines. One of the most important questions to ask yourself when buying the saw is: How does it feel? If the chainsaw is too bulky, it will be harder to use. Some of the best chainsaws are small and light. Here are a few tips: Look for aà non-kickback attachmentà to ensure your safety.Examine the chainsaw parts.Try out both gas- and electric-powered saws.à The main thing is to examine the saw yourself before buying. Thats something you cant do over the internet. Put on some work gloves, visit a few dealers and spend an hour or two trying out chainsaws. Thats the best way to ensure you buy a quality chainsaw that will last years.

Human resource-staffing Essay Example | Topics and Well Written Essays - 250 words
Human resource-staffing - Essay Example The first thing is that it is worth paying these individuals what they are worth or what they demand from you, if you want to attract them to work for you. Quite possibly because of their reputation for producing results, they are being targeted by headhunters and competitor organizations in the industry. So giving them the kind of compensation and benefits they want- of course within reasonable limits- coupled with a free hand in running most things will attract them to the organization (Berger & Berger, 2003, 35). Of course, we do not want a clash between two or more top performers, so budgets and areas of operation and control have to be carefully delineated, with the CEO making decisions if there is an impending conflict. Quite possibly a performance bonus or sweetener has to be offered if they are involved in an organizational turnaround, with stock options in tow. Developing a talent inventory for the most promising individuals in the organization and giving them ample opportunities to be responsible as well as get training, learning and development will help prepare a talent pool from within the enterprise itself. It is best to put such individuals under direct reporting of the top performing individuals, so that a talent pool is developed that could be used in case the top performer resigns, dies or is lured by a competitor. 8. Keeping an eye on the market and the top performing individuals in different areas of the industry can also help in filling important positions from outside if relevant talents are not available within the organization. I think that the best single practice I have learned in this regard is to be prepared and it is always best to have a succession plan or backup plan in place in case an important individual leaves the organization. This is possible if one keeps an eye on what is happening in the industry from time to

The major problem in investing in equities and bonds is that it is not possible to diversify and distribute investment risks. Diversification has been proved to minimize risk in investment. A diversified investment mix of equity and bonds in an assortment provides more expected return than a 100% bond selection with a lower risk than 100% investment in world equities. There are several reasons why I chose investing in the four listed companies: Goldcorp Inc.,Bank of Montreal, Apple Inc., and Tim Hortons Inc. One of the major reasons is that the companies have been making efforts to expand their markets and increase in sales. Increase in sales and profits leads to increase in the prices of stock prices. According to an economic outlook, investors project that the stock prices will increase. This implies that the prices of the stocks invested in the companies will increase. Some of the reasons behind the increase in stock prices in these companies include: Sales increase, New products and expansion to new areas and markets. The companies I chose have been making efforts to increase sales by relocating to bigger locations and offering different pricing offers and improved marketing techniques to encourage customers to purchase their products. Apple for instance has significantly
