Direction and Purpose Essay
Metaphors provide creative images for readers. They give flavor to literature and allow free interpretation of a piece; thereby making a conversation in a story, an image in a poem, a symbolism in the plot and such, more interesting. Through the use of such a figure of speech, the images are laid bare and presented fresh. This creates an interaction between the reader, the author and the piece; as readers are made to analyze the images presented and the idea that the metaphor is trying to introduce. It seems the poem, ââ¬Å"Manilaâ⬠, efficiently develops the metaphor that is the Philippines society during the colonial era, through a timeline. It takes the problem of colonial Manila into the modern Filipino mindset. The poem begins with an introduction [Lines 1-3], which gives us the first glimpse of the similarities between the city of Manila and the hermit crab. The succeeding stanzas [4-8] elaborate the physical conditions of the countryââ¬â¢s capital and finally, the poem concludes [l9-14] with the mentality upheld by the nation. To appreciate how metaphors lay bare Espinoââ¬â¢s ââ¬Å"Manilaâ⬠, let us analyze the imagery create in the poem, line by line. Unlike most poems, ââ¬Å"Manilaâ⬠begins with an epigraph from Nick Joaquin, which reads: ââ¬Å"Dust and crabs, dust and crabs.â⬠We can assume that this quote gives a foreview of what Federico Espinoââ¬â¢s poem will highlight. Though very little is conveyed in this line, we are able to suppose that the metaphor will hold significance to the poem proper. Dust may be described as either something that depicts age or some remains of an explosion. We also know of crabs as an animal that crawls and has claws. Crabs are also able to survive on land for short periods of time and can literally live on dust. ââ¬Å"Manilaâ⬠begins with the line: ââ¬Å"A hermit crab beside the tide of times,â⬠if we look at the concept of the hermit crabs as a description of Manila, the line merely tells us that time has passed. It tells us that Manila has an old history and that it has endured much. The next line: ââ¬Å"She bears the traces of her former homes/ the shells of foreign cultures and the slime,â⬠tells us that the countryââ¬â¢s history contributes much to its identity. The city has withstood much to the point that it is now isolated and delayed in comparison to the developments of other countries. The ââ¬Å"former homesâ⬠are the shells that the crab has already left behind. The ââ¬Å"foreign culturesâ⬠such as that of the Spanish, British, Japanese and Americans have all freed the country, yet their influences ââ¬â dating back to colonial times ââ¬â still linger. But as hermit crabs changes its shell, Manila now looks for a new ââ¬Å"shellâ⬠of protection as she enters another era ââ¬â whilst trying to retain its identity. Even with the passing of time, the mix of culture is still protected and preserved, which the narrator describes as both positive and negative ââ¬â implying that though the foreigners have given us a rich culture, they have made us endure much ââ¬Å"slimeâ⬠and shit (considering that slime is a gastropodââ¬â¢s mucus secretion) in order to take what was rightly ours ââ¬â freedom. In the succeeding lines: ââ¬Å"Now she looks for food as small waves comb/Upon the shore where bits of driftwood lieâ⬠, we now see a direction in the poem. Again it highlights how the hermit crab searches for something and we now see she looks for food. Keeping in mind that food is parallel to life ââ¬â since it is necessary in sustaining life ââ¬â the hermit crab looks for nourishment in a place which seemingly has very little to give. From Nick Joaquinââ¬â¢s ââ¬Å"Sa Loob ng Maynilaâ⬠, we understand the devastation in the city when it served as the center of the revolution, and we see that starting anew is difficult when one is left on what is being portrayed as a deserted island. As expected, ââ¬Å"she finds nothing in her hungry quest/ Instead she hears the raucous seagullââ¬â¢s cry/ Which is a shriek beyond the rock-ribbed nest.â⬠In these lines, the seagulls ââ¬â natural predators of the hermit crab ââ¬â are foreign countries. We can assume that not only are we looking up at the seagulls but that they are also in a position to take advantage of us. In relation to the Philippinesââ¬â¢ history, foreign countries are soaring. Other countries progress and it is a mockery when ââ¬â ironically ââ¬â the countries we defeated fighting for our independence are now more stable than we are ââ¬â they still rise above us. We are still beneath them in a sense to the point we have to crawl in order to get anywhere. These lines are merely creating the image of a third world country. All seems futile, especially when you have nowhere else to go. ââ¬Å"It mocks her as she crawls upon the sandââ¬â The sidewise movement of the hermit crab/ Which Dylan saw on a deserted strand/ And used as a metaphor in runes that throbâ⬠It is possible that Dylan represents a foreigner (since it is a typical name for an American boy) and he saw our ââ¬Å"aimless wanderingâ⬠and toke advantage of it ââ¬â however, this is more of a hunch than a legitimate argument. What is clear though, is the point of our sideways movement, which is the natural direction a hermit crab follows. By this we can concur that the movement has become innate. We are not moving forward. We want so much, yet work so little. Perhaps, these lines also imply that we search in all the wrong places. ââ¬Å"With life. Yes, this city is a pair of claws/ Creeping, crabbing with all its tragic flaws.â⬠These last lines of the poem summarize the intent of the entire poem. Here it is implied that the people of the Philippines are aware of the damage in their society. Slowly, almost lifelessly, the Filipinos attempt to move through the things we dislike in our country. We complain so much yet we do very little ââ¬â and perhaps that is our downfall. True there is no prefect nation, but in most nations you see a progression. In reference to Nick Joaquinââ¬â¢s opening epigraph, perhaps the dust is the remains of those countries that once colonized us. We never bothered to clean up what was left to us ââ¬â good and bad. Espino hints that perhaps that is why we are not moving forward, there is too much to fix all at once. And this can be related to what we call ââ¬Å"crab mentalityâ⬠or the Filipinosââ¬â¢ attitude of clawing at those who have gotten ahead to pull them back again. We ââ¬Å"creepâ⬠and ââ¬Å"crawlâ⬠in our own flaws ââ¬â in our own mistakes ââ¬â instead of picking ourselves and walking. It is our own claws that hold us back. The generalizations made by Espino are obvious. Though the title is ââ¬Å"Manilaâ⬠is it clear that the city, being the ââ¬Å"heartâ⬠of colonial Philippines, is a synecdoche for the entire country. And when all aspects of Espinoââ¬â¢s Manila are examined, we see that the metaphor is in the intricate, descriptive design of the Philippines as a hermit crab trapped on a deserted island. Though she is attempting to escape, she is crawling blindly in no particularly direction. It seems not much has change. Though ââ¬Å"Manilaâ⬠was written a long time ago, it is relatively surprising that the text paints Manila in a sad, accurate manner. We fought for our freedom. Now we merely struggle with it. It seems our nation cannot decide independently; like a hermit crab, we depend on our symbiotic relationships. We cannot survive alone and we rely on what can be give to us by those who ââ¬Å"protectâ⬠us. The dependence relayed in the poem explains why we have no direction, no purpose, and no resources. We are ââ¬â truly ââ¬â stuck.

The beneficial effects of nutrition on exercise performance Essay
Over the past 20 old ages. research has clearly documented the good effects of nutrition on exercising public presentation. There is no uncertainty that what an athlete chows and drinks can impact wellness. organic structure weight and composing. substrate handiness during exercising. recovery clip after exercising. and. finally. exercising public presentation. Carbohydrates are of import to keep blood-glucose degrees during exercising and to replace musculus animal starch. Recommendations for jocks range from 6 to 10 g/kg organic structure weight per twenty-four hours. The sum required depends upon the athleteââ¬â¢s entire day-to-day energy outgo. type of athletics performed. sex of the jock. and environmental conditions. Protein demands are somewhat increased in extremely active people. Protein recommendations for endurance jocks are 1. 2 to 1. 4 g/kg organic structure weight per twenty-four hours. whereas those for opposition and strength-trained jocks may be every bit high as 1. 6 to 1. 7 g/kg organic structure weight per twenty-four hours. Fat is of import in the diets of jocks as it provides energy. fat-soluble vitamins. and indispensable fatty acids. Dehydration decreases exercising public presentation ; therefore. equal fluid before. during. and after exercising is necessary for wellness and optimum public presentation. Athletes should imbibe adequate fluid to equilibrate their fluid losingss. Two hours before exercising 400 to 600 milliliter ( 14 to 22 oz ) of fluid should be consumed. and during exercising 150 to 350 milliliter ( 6 to 12 oz ) of fluid should be consumed every 15 to 20 min depending on tolerance. Before exercising. a repast or bite should supply sufficient fluid to keep hydration. be comparatively low in fat and fibre to ease stomachic emptying and minimise GI hurt. be comparatively high in saccharide to maximise care of blood glucose. be moderate in protein. and be composed of nutrients familiar and good tolerated by the jock. Eating before exercising. as opposed to exerting in the fasting province. has been shown to better public presentation. The size and timing of the pre-exercise repast are interrelated. Because most jocks do non like to vie on a full tummy. smaller repasts should be consumed in closer propinquity to the event to let for stomachic voidance. whereas larger repasts can be consumed if more clip is available earlier exercising or competition. Sums of saccharide used in surveies in which public presentation was enhanced have ranged from about 200 to 300 g saccharide for repasts consumed 3 to 4 H before exercising. Current informations are assorted refering whether the glycemic index of saccharide in the preexercise repast affects public presentation. The saccharide consumed should give chiefly glucose ; fructose entirely is non as effectual and may take to diarrhea. although mixtures of glucose and fructose seem to be effectual. If the same entire sum of saccharide and fluid is ingested. the signifier of saccharide does non look to matterââ¬âsome jocks may prefer to utilize a athletics drink whereas others may prefer to eat a solid or gel and consume H2O. Presently. the usage and recommendation of ergogenic AIDSs to jocks is controversial. Some wellness attention professionals discourage the usage of all ergogenic AIDSs. though others suggest they be used with cautiousness and merely after careful scrutiny of the merchandise for safety. efficaciousness. authority. and legality. Athletes should non utilize nutritionary ergogenic AIDSs until they have carefully evaluated the merchandise. as indicated above. and discussed the usage of the merchandise with a qualified nutrition or wellness professional.

PART A- IDENTIFY WITH REASON, THOSE GROUPS OF PEOPLE WHO ARE PREDISPOSED TO DEVELOPING DEEP VEIN THRO - Essay Example 05), elderly individuals, obesity, prior history of DVT, venous stasis, local compression on the veins, and acute factors like severe dehydration (Guirguis, 2000). DVT also can occur from iatrogenic injury of the femoral veins (Wood, 2000; Joynt, 2000), malignancy (pancreas, lung, ovary, testes, urinary tract, breast and stomach), after major surgery (orthopedic, thoracic, abdominal and genitourinary procedures), following trauma (fractures of spine, pelvis, femur, tibia and spinal cord), burns, pregnancy and the postpartum period, estrogen use, hypercoagulable states (deficiencies of protein C, protein S, fibrinogen, factor V, factor VIII, factor IX, factor XI, prothrombin, and antiphospholipid antibodies), venulitis (thromboangitis obliterans, Behcets disease, and homocystinuria) (Creager & Dzau, 1998), end-stage renal disease and congestive cardiac failure (Casserly, 2000). Thrombogenesis is a finely balanced process between coagulation and fibrinolytic pathways. The interaction between plasminogen activators (e.g. tissue plasminogen activator) and inhibitors that modulate this activity (e.g. plasminogen activator inhibitor, PAI-1) influences the fibrinolytic system. Plasma fibrinogen determines plasma viscosity, blood flow, affects platelet aggregation, blood viscosity, interacts with plasminogen binding and along with thrombi, mediates the final steps in clot formation. The levels of fibrinogen associates directly with age, obesity, smoking, diabetes and LDL-C and inversely with HDL-C, alcohol use, physical activity and exercise level. Increased fibrinogen is also associated with many different forms of vascular and inflammatory disease. Impaired fibrinolysis, as demonstrated by the elevated levels of plasminogen activator, is seen in obese patients, and explains the increased risk of thrombosis and other vascular disease in the obese (Chung & Lip, 2004). Virchowââ¬â¢s classical triad of factors that lead to the development of thrombosis (thrombogenesis)

Financial analysis of Community Health Systems and HCA, Inc Assignment
Financial analysis of Community Health Systems and HCA, Inc - Assignment Example There are many reasons for someone to explore a firmââ¬â¢s financial statements. Investors use it to explore potential returns on their capital investment, managers explore to assess performance, and the government reviews them for legal compliance. The final analysis for HCA & CHS will be presented from the prospective of the investor. In order for the investor to understand the return on an investment, he/she must examine the firmââ¬â¢s quality earnings. Quality earnings are different from profit. Profit could mean the firm is just breaking the even point that enables the firm from incurring losses. Maybe the profits are being absorbed by debt. Many firms hide debt in the financial statement notes. Consequently, investors willing to invest in a given organization should not evaluate the viability of the investment from the face value of the financial statements. Assessing a firmââ¬â¢s worth involves a deeper understanding of the firm and its industry. Ratio analyses are ve ry useful in that understanding. In the next few pages, you will find a vertical ratio and horizontal analysis for subject firms. HCAââ¬â¢s financial data was easy to comprehend due to the concise and clear presentation of the consolidated statements. In addition, the accompanying financial notes helped in understanding the origin of the figures in the financial statements. Most of its financial data are easily translated into terminology used in the Excel template. The financial data of HCA was presented in the millions while Community Health Services was listed in the thousands. To make the two firmsââ¬â¢ financial statements more comparable, Community Health Services numbers were divided by 1000 to convert it to millions. Cost of goods sold for the firms is actually labeled ââ¬Å"Revenues before the provision for doubtfulâ⬠. The healthcare industry has a large provision for doubtful

Understanding and meeting the needs of elderly citizen in the Thesis
Understanding and meeting the needs of elderly citizen in the hospitality industry - Thesis Example Understanding and meeting the needs of elderly citizen in the hospitality industry After extensive literature review, the methodology was explained. The findings have been given in chapter IV and all objectives have been achieved. This was a qualitative study based on literature review and survey questionnaire. The study concludes that the elderly segment is a high potential group with several sub-groups within the group. The demographic changes pose several challenges to the hospitality sector but it is worth working towards these challenges. This is a heterogeneous group with their own characteristics. They are fun-lovers and have the money power to indulge in comfort, convenience and luxury, as their individual situation permits. Their needs depend not just upon the chronological age but also on the biological and the psychological age. The self-concept and the self-image also impact their needs and wants. All these again depend upon the level of education and income level. This has also given them the consumer power as they have better control over themselves, over their needs, over their expenses and how they want to use their money. They have reached a phase where they value their own self and would like to spend on self-development. The hospitality sector can benefit by taking note of the recommendations made in Chapter IV. This is a segment which offers tremendous scope for growth and the segment is growing. However, needs and wants keep changing with every generation and hence the hospitality sector should conduct regular surveys and the market research should be ongoing so that they can keep themselves abreast of the changing consumer preferences of the elderly segment. The study has made suggestion for further research on the subject before highlighting the imitations of the study.

Along with the life span, the quality of life too has increased with advanc ements in technology and medication. Advancing age brings about changes in consumer needs, wants and abilities (Meneely, Strugnell & Burns, 2009). Many studies in the past have attempted to describe and understand the elderly consumer but the elderly consumer segment has gained importance in recent years because of their size and buying power (Meadow, Cosmas & Plotkin, 1981).

Tracking Progess in Healthy People 2020 Across the Country Essay
Tracking Progess in Healthy People 2020 Across the Country - Essay Example In this discussion, an evaluation of how Iowa has adopted these objectives and the challenges being faced in their workability will be considered. Although the objectives enshrined in the Healthy People 2020 are articulate and wider in scope, it is notable that they are not fully embraced by the states within the United States of America. Iowa is one of the states that has not fully adopted these objectives despite the fact that the essence of the objectives is an all round support of the health of the citizens. Although Iowa has incorporated a number of objectives in its health promotion strategies, the espousal has been tailored to suit the Iowa communityââ¬â¢s health needs in as far as the individual differences in the population are concerned. As such, most of the objectives have not been fully adopted the way they are in this state. Going by the Iowa Health Improvement Plan 2012-2006, the objectives of Healthy People 2020 could not be practical enough given the high levels of disparity among the people in Iowa. One of the main challenges in meeting these targets is the scarcity of resources. (Sharma & Romas, 2011). A good number of Iowans are low income earners and this incapacitates the economy that is supposed to meet the financial demands implicated in these health objectives. (Shi & Stevens, 2010). For instance, one of the most anticipated health problems in Iowa is diabetes. However, coming up with measures that are supposed to address this problem in time is such a big challenge given the scarcity of resources. (Shi & Stevens, 2010). Given this, only a partial and tailored adoption of these objectives is possible. In conclusion, the health promotion ideas enshrined in Health People 2020 can prove to be quite effective if well adopted. However, as seen through Iowa State, there is a deviation in the manner in which these objectives are being worked on. A number of challenges are imminent, with the shortage of

CASE STUDY Example | Topics and Well Written Essays - 250 words - 1
Case Study Example Consultant, while not very well versed with the issues in hospitality industry, was nevertheless of the view that if turnover is a recurring or chronic problem, one must tackle it differently. In this case, while turnover was recognized as consistent problem, recruitment remained the only solution. Gunterââ¬â¢s assumption that issue needed to be looked from different perspective was correct. Consultantââ¬â¢s advice inspired him to investigate turnover and ex employees who had left for better prospects. The resort was seen as major training institute by other resorts who thought of Green Mountainââ¬â¢s alumni employees as top performers. Hence, Gunter took new recruits as opportunity to get hard working and committed workers. The recruits as career building would be able to give excellent level of service and thereby, contribute to resortââ¬â¢s success. It was sound strategy because there will not be shortage of potential top performers as they would continue to wait for their enlistment in the resort. Recruits are motivated because working in the resort is good for career

Study of Banking Crises and Failures Dissertation
Study of Banking Crises and Failures - Dissertation Example The number of studies and research papers probing causes and types of bank failures is substantial. These research efforts have presented wide ranging evidence of bank failures from across various continents and cover the period as early as the Great Depression period of 1930s to as recent as couple of years back just prior to release of final Basle II framework in June 2004.Great Depression was a period of a downside economic shock and affected the larger economies in a major manner. While general economic outlook was highly pessimistic in these years it often precipitated in economy wide panics running through money and capital markets. Several research papers have studied the effect of the panics on the banking system and focused on enumerating the timing and geography of bank failures during panics (Wicker,1996).While some other research efforts have attempted to explain if panics were one time abnormal periods that resulted in the failure of even solvent banks by comparing banks that failed in panic periods to banks that failed outside such periods and finally tracing the survival of some such banks.The former paper arrives at the conclusion that banks failing during panic periods were weaker than banks that survived and not quite similar in financial characteristics to banks that failed during non-panic periods. Literature has identified four major panics were identified in the Great Depression period (1930-1933). Friedman and Schwartz attribute the 1930 panic to a contagion of fear"

Women in the Middle Ages Research Paper Example | Topics and Well Written Essays - 1500 words
Women in the Middle Ages - Research Paper Example The medieval world is said to be exceptionally customary. Ladies had zero part practically to play in the nation on the loose. In the city, society would have effectively overseen what occupations a woman could perform, and her part in a medieval society would have been to help her mate. And in addition doing her daily chores, whether in a town or at home, a lady would have had numerous obligations concerning her job (Hanawalt 39). The duties played by women in this period were those that helped men to work harder or improve their efficiency. The responsibilities include some tasks like cooking for the man of the house. The women were expected to carry out this duty by the society to help men carry out their duties continuously. Men could now feel motivated as they did not waste any time in the house doing jobs like preparing meals. Jobs are mostly believed to be available in the urban regions. Inside a town, ladies would have done a significant number of the undertakings men did in the area. Even so, they were lowly paid for completing the same piece of the task. Archives from Medieval England identifying with what the normal individual did are uncommon, yet some still exist which inspect what ladies living in the towns did. For example, when procuring a commodity, a male could get 8 pence (Rexroth 219).When a woman completes the same task, she was paid 5 pence. For food making, men would receive 6 pence a day, while women got 4 pence (Hanawalt 219).

Community Assessment and Analysis Essay Example for Free
Community Assessment and Analysis Essay Yuma Community Of all the problems faced by Yuma community, along with the state ranking for teen births, the community also takes third place. (County Health Rankings, 2012). Programs that will help to educate teens on the importance of using birth control in order to stop undesirable pregnancies are a rising need within the community. Additional health problems for this community include obesity in the adolescent population; in 2005, the Yuma community had approximately thirty six percent of its adolescent in obese category, comparing to twenty nine percent in the entire state. (Centers for Disease Control, 2005). In the state The Steps program steered by the Nutrition and Physical Activity Self-Assessment for Child Care Centers, targeted five communities and over 2,200 children mostly decreasing sugary drinks, cumulative fiber intake and wholegrain foods. The state of Arizona as a whole is facing another larger issue in the Vaccination rate. World Health Organization mandates 95% of vaccination rate for the entire population. The rate of vaccination set by the state is 90% and the current rate of the State is 70%, which far below the target goal and is alarming. (Arizona Department of Health Service, 2011). Arizona Republic magazine reports that, I the upper and middle class one of the reason for non-compliance with immunization is fear of causing Autism. If given opportunity, the lower class families seem to show better compliance with immunization when cost factor is elicited (Alitucker, 2011). Location and climate play an important role in the health issues of this community. Mexico and California are the two borders of Yuma community. The economy and budget gets divided among law enforcement and Border patrol. The increasing crime rate requires the state to contribute a major part of its budget towards law enforcement and protection of its citizens, which takes a down toll on the availability of the public health res ources initiation. A health initiative, to utilize funding ,such as to ensure free water supply to all the community could benefit to elicit problems related to Dehydration in this desert climate. Educational status is another concern of this community. Hispanic population accounts for sixty percent. High rate of drop outs from school is considered to be related to language barrier. Education can play a vital role in enabling the community to critically to acknowledge problems and to find remedies to stay healthy as a community. Yuma Community can benefit from added funding to support and to maintain programs to stay healthy as a community. With the limited funding, community is able to assist with citizens with housing, health insurance including dental coverage in the community (Need Help Paying Bills, 2011). Yuma community cannot be considered totally poor, because the community consists of one main acute care hospital and two smaller hospitals inside a sixty mile distance. But the lack of Medical specialty such as Cardiac surgeries or those require high skilled treatments are not easily available within the community. The nearest specialty hospitals for children and adults are in Phoenix. Fatal accidents accounts as first reason for the higher death rate in the community. In 2007, the total death rate for the city of Yuma is higher than the state average in total, directing to fatal accidents as the source (Yuma, AZ, 2012). The functional health assessment of Yuma community, we have learned that there are many problems that can be considered in the County. Some of the key problems prominent are high rates of obesity, alcoholism, drug addiction, and teen pregnancy. Though the total obesity rates are close to national average, the statistics show that County has a much higher rate of adults that do not exercise. In order to care for the mental health needs of the community, the County has six addiction treatment centers. The suicide rate remains high even with the availability of mental health service within the community. There are two military bases to serve the community. The increased poverty rate is believed to be the reason for higher addiction rate. Yuma is the eleventh largest city in the state, but they have the third highest rate of teen births. There are several facilities in the county to assist socially with issues related to parenting; poverty, and employment, addition of more funding and facilities can be helpful to the community, to rebuild a healthier community. Even with all of these problems, several people are proud to call Yuma County their home. The friendship felt within the communities such as a military social function, the local bar, at the river, or out on the ridges leads many people to find a pleasant and happy life here. There are plenty of resources to help the population discover the services they require, and to enjoy a cleaner and healthier environment. With an added focus on the health issues, Yuma community can stay healthy and happy. Sleep and rest. The sleep habit of the people in Yuma is mostly uninterrupted. Most of them are sleeping 6-8 hrs at night. Going to bed At 10 pm and waking at 0600.There are full time workers with 12 hour and 8 hour schedules. Some of the members are doing the part time work, some are doing voluntary work. Some of the older population states that very seldom they use sleeping pills to promote sleep. Few of the ladies have the habit of drinking, hot milk before going to bed, limited number of ladies have the habit of drinking wine before sleep. Some of the adult populations have sleep apnea problems. Sound sleep indicates sound health of mind and body. Cognitive/Perceptual The primary language for this community is English. Increasing numbers of older adults have access to and are knowledgeable about computers. They are well educated and most of them are well employed. No communication barriers noted among this group. Libraries and internet facilities are available in the community for the members use. Most of the older people using glasses for the visual impairment and few of them were using hearing aid for the auditory impairment. The people go to the community college for short term career goals. It was interesting to note that some of the older people are continuing education. Self-Perception/Self-Concept Yuma city population consist of 29.6% under the age of 18, 11.9% from 18 to 24, 27.1% from 25 to 44, 17.5% from 45 to 64, and 13.9% who were 65 years of age or older. Agriculture is a major industry in Yuma, topping Arizona counties in agricultural sales. In addition, Yuma County also houses the US Marine Corps Air Station and US Army Yuma Proving Grounds are located near Yuma City. Yuma County is thus characterized by large transient populations, as it is a temporary place of residence for agricultural migrant workers, winter residents and military personnel. With the beginning of the winter growing season in October, the county has a large influx of migrant farm workers and winter residents. In 2008, Yuma County was a temporary home to 41,314 migrant and agricultural workers and to 12,600 winter residents (Yuma Special Area Statistical Profile-2008). Hunting is a popular sport, as the county offers a variety of different types of game. Fun, Friendship, Freedom and fulfillment are the mission of Yuma County. The members are bound together by these missions. Some of the major attractions in Yuma County are the historical Territorial Prison, the Yuma Crossing Historic Park. Other great places to visit are the Kofa Mountain Range and Wildlife Refuge, and Martinez and Mittry Lakes. Sexuality/Reproductive The people in Yuma County believe that teen pregnancy and/or STDs are a major health issue in Yuma County. Youth and teens are most affected along with Hispanics and Native Americans. Compared to the 2010 health targets, however, Yuma County falls short in reducing teen pregnancy among 15-17 year olds, prenatal care, low birth weight, and fetal/infant death. The family environment was mentioned as a factor contributing to negative health outcomes stemming from the breakdown of the family. One interview respondent felt that ââ¬Å"children do not have a sense of self-worth or self-esteem and are no longer being nourished; only sustained.â⬠Interview respondents felt that parents do not have time for their children and there is a lack of communication between parents and children. Further, they felt parents are not involved or are not educated on how to take care of their childrenââ¬â¢s health. Most of the members are having annual physical checkup with mammogram and Pap smear. Community awareness program including the transmission and prevention of STD/ HIV / AIDS are being held in the community. Coping/Stress An important aspect of healthy ageing is the ability to cope with and adapt to life conditions and transitions. Participation in social activity helps the Yuma county people to cope with transitory, acute and chronic stressors in their lives. The accumulation of chronic health conditions can negatively affect psychological wellbeing and quality of life. In addition to health-related stressors, the death of a spouse is often a challenging loss for older population. Related to this, social isolation, loneliness and loss of social support systems may be additional stressors in older peopleââ¬â¢s lives that affect psychological wellbeing.

Concept of Crosswall Construction for Earthquake Hazards
Concept of Crosswall Construction for Earthquake Hazards 1. INTRODUCTION The aim of this report is to understand the basic concept of crosswall construction, and a proposal for Armature Crosswalls to be used as earthquake hazard mitigation for reinforced concrete and masonry infill-wall buildings vulnerable to collapse. RC frame and infill construction is common throughout the world and often has proved lethal in earthquakes. The paper traces the history of masonry infill construction from pre-modern forms that have shown earthquake resistance in the past, to the early modern steel skeleton frame buildings that survived the 1906 San Francisco earthquake. the construction flow at real time in step by step procedures and quantifying the benefits and studying their applications. This is done by making a comparison in usage of the same technique in two different countries namely India and the United Kingdom. This comparison is aimed at producing an insight into the technique and to identify the areas of improvement. 2. Crosswall construction 2.1 Definition: Crosswall is a modern method of building construction using division walls which transfers the floor loads through the building to the foundations. The name crosswall itself signifies the masonry connection is on either sides of the main wall. It employs concrete components like lift and stair cores, precision engineered (highly skilled), and precasted in the factories. 2.2 Applications: This type of pre-cast single-skin or flat panel concrete construction is becoming more popular in commercial applications such as hotels, motels, prisons, military barracks and student accommodations. These types of structures up to 16 storeys have been finished in U.K using the crosswall technique. The use of such panels can result in fast, simple construction process on site followed quickly by finishing trades. Crosswall is mainly used for medium and high rise buildings. 2.3 Benefits: Cross wall construction method reduces the wet trades and creates very early dry boxes for subsequent trades. This helps in speeding up the construction process without delay in work. Crosswalls also helps to eliminate internal cladding and other items such as party walls because the concrete crosswalls and floors do more than load carrying system. Crosswall technique reduces the labour onsite. A precast panel provides concrete frames without structural down stands. Cross wall construction which has been developed for providing very fast and high quality in repetitive accommodation units such as hotels and the opportunity for multi storey apartments is rising, student accommodation buildings, stadiums etc. but the crosswall technique optimisation in low rise buildings is minimal(single houses) because the dimensions of each room may not be the similar. The Crosswall construction is incorporated with a series of both horizontal and vertical ties which are designed in such a way to prevent the failures and collapses according to building specifications. Other precast work can be started simultaneously before the precast units are erected. The crosswall buildings have less maintenance service and have good acoustics values. The acoustic performance of crosswall is excellent because of its mass and effective damping. Crosswalls reduces the risks of failing pre completion acoustic tests. (The Concrete Centre, 2006) Pre cast walls and floor units are more than just a structure (highly effective in costs, speed, early start for other trades, and provision of fire separation panels), wall panels are provided with good finish and air tight tolerance. Tight tolerance enables fitting of bathroom pods, carpets and built in furniture. Flat pack construction is very quick and cost effective because it reduces the material waste on the site and the party walls are largely eliminated. The separation of acoustics and additional finishes are reduced as the wall panels provide the sufficient airborne noise separation. Thermal mass is provided by concrete and the thermal is utilised in crosswall constructions because the concrete widely spreads on the unfinished surfaces and the thermal mass reduces the risk of over heating in summer season by keeping the surrounding cool.( Doebber, Ellis M.W; 2005) The main features incorporated in cross wall construction are Direct decorative finish to the walls with only minor pre decoration treatments. Solid room sized slabs pre finished for direct ceiling decorations. Reduced structural zone without downstands. Cross wall system generally utilises stair cores and lift cores for overall stability. Pre fitted windows eliminates internal cladding. Optimal methods of floor construction, allowing flexibility for individual client requirements. Construction of stairs and lift cores can permit early access for subsequent trades. (The Concrete Centre, 2007) 2.4 Limitations: In spite of several benefits offered by the precast panels, it has found that there is no wide acceptance of the precast panels in construction because of Highly skilled engineers or labours are required for manufacturing, placing and erecting the moulds on required positions. Lack of awareness and initiatives especially in Indian construction industry because of invariable labour intensive methods which leads to delay in the construction and that result in cost over-run and poor workmanship. Shortage of skilled and semi-skilled personnel availability may bring poor finishes, leakages in the buildings, corrosion of structural elements. These defects can be only minimised by the use of mass scale projects such as schools, offices, hospitals and other similar projects.(A.B.Shah,2005) Precast wall panel construction may be more or equal expensive as masonry construction because it mainly depends upon the transportation of offsite fabricated materials to onsite. (Havel.G, 2006) Difficult to transport heavy weight and size of the precast panels. The profit margin is very low in the small scale constructions. For single and two storey dwellings it would be typical to use single storey height walls panels between 90-300mm thick concrete for external walls and 70-100mm thick panels for the internal walls. The variation in designs leads to the problem and the single housing clients are not happy with the precast technique even though it provides a higher quality and good finish. This crosswall technique is mostly used for large repetitive structures may not be used for small scale construction like individual housing because the crosswall is more expensive tool when compared. (Glass.J, 2000) 2.4.1 Fire Conditions: The building with large precast wall panels often has high ceilings and heavy fire loadings, as in retail stores, factories and warehouses. The fire in one of these occupancies require large volumes of water from large lines, if the fire is not controlled master stream appliances will be needed. The fire in large precast buildings is likely to cause an early collapse of the roofs even if they are no weak connections. In this type of precast panel construction all the parts of the building are tied together as part of a structure, the roof collapses are more likely to tip the walls inwards and outwards. As we know, the roof supports are more securely connected to the walls, the chances of roof collapsing is high before the wall connection fails. The failure of any part of the structure may affect the stability of the other parts of the building. (Havel.G, 2006) 3. Historical background: The precast concrete wall panel system was devised in England by William H.Lascelles (1832-85) of Exeter. In 19th century the pre-casting concrete for the structural purposes was started. Francois Hennebique (1842-1921) first introduced precast concrete into cast in-situ flour mill in France. White and Morris had given the historical accounts of the early development on precast concrete. (Elliot.K.S; 2000) Later in 1930s the use of precast as been expanded by companies such as Bison, Trent concrete and girling. Whilst precast concrete usage was stand at the first place it differs from country to country. One of the reason was the structural timber became more limited in some of the countries which led to development and improvement of precast usage. During the next 25 years the development in the precast frames, precast cladding as increased the market share to around 15% in industrial, commercial sectors. (Richardson.J.G, 1973) Since the 1990s, a significant amount of research has been conducted on the seismic behavior and the design of precast wall paneled structures that do not emulate the behavior of cast-in-place reinforced concrete construction. 4.Development Of Precast Concrete Panel Frame Systems: Precast panel frame systems have been successfully emerged from the research use of post tensioning between the precast beam and columns to achieve the lateral load resistance needed in seismic areas. (Seismic design of friction-damped precast concrete frame structure) For the Docklands project on constructing student accommodation blocks in London, the concrete was prefabricated in Belgium and transported because the northern Europe was only able to cope up with the demands of the project and other small local markets were tightened. Precast concrete wall panels in buildings speeds up the building process by adopting the precast concrete moulds. Decorative and light weight blocks have a great to offer visual values and technical values. The small store buildings from the precast industries offer excellent means of construction within the budget. The farm buildings, ware houses, industrial buildings are required to be constructed on exposed sites so the materials of standard precast frame components are supplied. Precasting of simple lintels offers opportunities of time saving on the site. The schools, universities are built by using the precast modular components. 4.1 Comparison of Conventional and Large precast panel Construction (Shah.A.B, 2005) The above table clearly signifies the benefits of large precast construction over conventional construction methods in various fields. 4.2 Structural Superiority: The precast panel structural system can be quiet efficient compared to other systems and it was tested and proven. (Fintel.M, July1991). In cast in-situ concrete structures, the large stresses may built up in the structure due to the curing, shrinkage, creep, temperature etc. However no such stresses are built in large precast panel systems during casting. Due to these special characteristics of large panels it has proved its efficiency for more than 50 years in Europe, America and other developed countries. (Shah.A.B, 2005) 5. Precast Concrete Panel Manufacture Process 5.1 Casting: Precast concrete panels can be manufactured by various casting methods. 5.1.1 Wet casting : It is generally used for small number of units having similar specifications. The moulds are manufactured by heating them in the enclosed and covered zones. Skilled engineers design the type of moulds depending upon the requirement for the project and also under the guidance of trained supervisions. As this casting is used for small units, it can be manufactured manually depending upon the number of units to be prepared. This casting can be provided for small housing. Wet casting provides the concrete in the cube strength ranging from 21 to 50N/mm, the slump varying from 0 to 175mm with a compacting factor varying from 0.8 to 0.97.(specifications are derived from CP 110 Unified code for structural concrete) 5.1.2 Gang casting: It is usually used when the moulds are combined together into a large unit assembly. The gang casting is developed by the modification of wet castings. The gang casting could be used when the similar unit requirement is more. For example: gang casting can be used in the production of stair case in the multi storied buildings. The main factors for adopting gang casting process is because of the designed units, and the general components of concrete. The gang casting can be arranged horizontally and the outputs which are achieved from gang casting can be more enhance in the stack casting. The main advantage of gang casting is it allows the concrete to place faster and than the concrete is compacted with the help of immersion-type vibrators. The greater accuracy of the component units are produced with the gang casting. The gang moulds are tied up in series so that the pressure loading on each individual unit is counteracted by the adjacent units, by this way it reduces the number of tie members. The gang moulds can be used for long horizontal spans, but the filling of gang moulds must be carefully controlled such that the intermediate moulds are not subjected to differential loading which may cause deflections and waves along the line of moulds. (Gibb.A, 1999) 5.1.2 Stack Casting: Stack casting is the slight modification to the flat and gang casting units. In this casting process gang moulds are filled and hardened after the hardening process the divider plates are driven into the mould up to an appropriate depths so that the next layer will be ready for casting. Stack casting is used to produce A frames and can be used in the repetitive structures such as prisons constructions. All the rooms are of same size and dimensions. Precasters have found that the incorporation of through holes, barrels or by insertion of anchors allows fastening the mould sides and bring them to the subsequent positions with exact casting thickness. 5.1.3 Battery casting: It is mostly used on wider scale, battery moulds has become more popular in large concrete wall panel constructions and the casting technique is also used for the manufacture of floor slabs and for decorative cladding components. The battery casting can be used in the manufacture of L shaped components such as balcony elements and lift enclosures. In this type, the units are generally cast in batteries of two or more. The battery mould can also have eight to twelve cells in the same mould. The changes on the casting process which provides a continuous casting, hardening, and curing schedule prior to de moulding. The battery mould which basically contains a series of plates that are spaced a part by the other mould members. A Battery mould allows high density of casting to be carried in the available space. Care and proper supervision is required in the assembly operations so it results in securely tied moulds which will be impossible for the concrete member to get separate from the mould. (Richardson.J.G, 1973) 5.2. Direct Casting and Inverted Shell Procedures: The precasted concrete panels can be obtained from the flexible formwork. The fabric formwork can be used to produce two basic types of concrete panels such as direct casting and inverted shells. In the direct cast panels, the concrete moulds are formed by the sandwiching fabric between the two rectangular frames. Firstly, the lower frame has the intermediate supports place inside it. The lower frame is X- shaped intermediate supports. The fabric membrane is than prestressed between the lower and intermediate supports. Finally, the upper frame is placed over the membrane and than aligned with the lower frames. When the concrete is placed in the mould, the fabric form bends downwards and creates three dimensional tension curves between the available supports. Using the direct casting method, a single membrane can be moulded to form different varieties of designs by simply changing the design of the intermediate supports. The produced precasted frames with different designs can be used as various building components. The direct cast panel can be used as moulds to produce light weight shaft panels with compressed shells are caste from the mould. The panel has a minimum thickness of 38mm at the apex and a maximum thickness of 127mm at the perimeter and the diagonal X beams. The two glass fiber reinforced concrete panels can also be produced by optimising the same process of tilting the direct cast panel to produce a compression shell panel. The final obtained glass fibre reinforced concrete panel cast from the mould which significantly varies in thickness from 13 to 38mm. Unlimited desired number of different pattern or designs can be produced from these methods. Each intermediate supports produces its own set of compression shells. The moulds can be produced by providing the compression resistance to different load patterns by the changing the loading which is used in direct cast mould productions. This method helps in developing an architectural quality concrete finishes using the industrial concrete mixing. Also expands the architectural potential of concrete constructions. But the problem was identified that there was no suitable method for predicting the magnitude of deflections in the formwork membranes under the variety of loading and also structural behaviour of some of the structures are not examined, precise engineers may solve the problem of structural behaviour in the precast concrete panels. (West.M, April 2004) 6.Crosswall Construction Procedures Precasting the elements such as foundations, wall panels, floors, stairs, chajjas, water tanks are manufactured at the factory and they are directly installed on the site. 6.1 Foundations: The foundations along with the walls up to the plinth levels can be cast by using M20 grade concrete in the factories and further construction can be processed by using precast panels. 6.2 Precast Wall Panels: The precast wall panels can be made of concrete with the reinforcement provided as per the specifications. The wall panels can be cast in horizontal positions and than they are lifted from the casting beds after the concrete attains minimum required strengths. They are three main types of wall elements that are solid panels, panels with door openings and panels with window openings. 6.2.1 Sandwich Panels: The sandwich panel which involves a precast concrete outerleaf, and the choice of simulated stone finishes or facings, insulating layer and a blacking leaf of plane grey concrete. The insulation which is installed under the factory conditions is well protected by the concrete. The thickness of the insulation contained in the sandwich panels can be varied to achieve the required U-values. The precast concrete sandwich panels are often used for the building exteriors cladding and also serves as shear walls. The two sandwich layers are generally connected by the stainless steel connectors, which may consists of wind and the shear connectors. Several insulation types such as mineral fibre insulation materials can be used. A cavity can also be introduced if necessary. Mineral fibre insulation is environmentally friendly, fire resistant when compared to the expanded polystyrene products. The sandwich panels may support floors, slabs and beams. The main advantage of the load bearing panels is they may not require perimeter columns and instead increases the floor area and gives flush wall profiles. The applied finish panels may include terracotta, glazed bricks, tiles, granite, and limestone. A panel may incorporate more than 1000 bricks or 100 stones. (Dawson.S, 2004) The sandwich panel system which includes polystyrene insulation sandwiched between the two concrete walls. The interior of the sandwich panel is thicker because several studies as shown the thermal capacitance of benefits are greater when the thermal capacitance is within the insulation barrier (Kossecka Kossny, 2002) The two types of precast concrete panel systems are One is waffle precast concrete panel system which is currently used in the light commercial and residential industry and the other is sandwich precast concrete panel system which represents the available wall technologies which has greater thermal performance than the waffle panel system. The inner leaf of the sandwich panel may be used as a load bearing structural element for giving support to the floor units. This provides more efficiency to the construction process and minimises the need to integrate different trades. Techrete Company has manufactured the load bearing sandwich panels for Dublins city centre; the city centre was designed by OMahony Pike and for the first time the sandwich panel was used in a structural capacity on residential development. The sandwich panel provides very strong, durable, energy-efficient and fire resistant cladding systems. All the panels are manufactured in the factory and they are Just in time delivered to the site, they are enabled to provide very high quality finishes. Construction will be much faster and the load bearing walls panels they provide both structural support and external finish, the labour on site is minimised. (Taylor.P.J, 1992) Most of the precast concrete cladding system comprises of a single layered structural concrete panels which are manufactured in the factory and than installed on multi storey buildings with a weather resistant external finishes. Sandwich panel generally contains insulated material between the two precast layers. Techrete is one of the leading precast concrete manufacturers which has expanded the range and potential of the sandwiched panels. The Techrete company has introduced the precast panels in stone and bricks. The air cavity can be fixed in between the panels and they can be integrated as a part of load bearing structures. 6.2.1.1 Two-Wythe Sandwich Panels: The precast concrete slabs are constructed by two Wythes of concrete which are separated by thermal insulation layer. Two Wythes panels are provided with strong concrete which enables both lifting and handling. The solid concrete may also have catastrophic impact on the thermal performance on the precast concrete panels. The research was mainly directed towards the development of precast concrete three-Wythe sandwich panel with the improved thermal performances. Often, both the concrete Wythes are of same thickness and the surface of the exterior Wythes may include the architectural panels. The panels with two concrete Wythes and one insulated layer are referred to as two-Wythe panels. (Lee B.J,Pessiki; 2006) 6.2.1.2 Three-Wythe Sandwich Panels: The three Wythe panel which usually as three concrete Wythes and two insulated layers, those are connected by solid concrete and they are staggered in location so that no concrete path extends directly through the entire thickness of the panel. In practice, the three-Wythe panels are evaluated by estimating the thermal resistance (R-value) using the finite element methods. Three Wythe panel was developed to reduce the thermal bridges which were produced by solid concrete. Generally the thermal performance of three Wythe panel is evaluated by estimating the R-Values (thermal resistance) using finite element methods. The benefits of three Wythe panels are: The concrete connection between the Wythes allows improving the thermal performance over the two Wythe panel. The increased overall panel thickness may lead to increased span capability, this how which increases the usage of sandwiched panels. But the three-Wythe sandwiched panel may not be applicable for all scenarios because it increases the production time and production costs when compared to two sandwiched panels. On the whole three Wythes panels provide greater advantages in thermal performance than two Wythe panel but with higher cost and time productivities. (LEE, PESSIKI; 2003) 6.2.2 Tilt-Up Panels: The tilt up technique which combines the advantage of precast walls with other benefits of site casting, the size and the thickness of the panel is reduced. The tilt up construction had grown more rapidly with respect to the increase in the demands for more durable and economical buildings. The use of WWR(wire welded reinforcement) in the tilt up panels is relatively new concept. According to concrete international there are inherent advantages and disadvantages to the use of the WWR. (Griffin.J, 2003) WWR (wire welded reinforcement) mats are manufactured in the plant-controlled environment, which gives the correct number of bars that to be placed in the panels depending upon the additional drawings. In the fields the prefabricated mats give assurance that the bars do not bunch or free float together in the plane of reinforcement, step- through meshes are well maintained which offers the workers the ability to step between adjacent bars, reduction of labour on the site. Tilt up panel can be reinforced in less time because of the labour reduction. This wire welded reinforcement(WWR) may be used in joining the precast concrete walls and may finish the work very quickly without the need of excess labour and has an advantage in reducing size and thickness of the walls in multi-storey structures. 6.2.3 Double wall precast panels: Double wall building technology means that both sides of the wall and the floor components are form finished. The interior surfaces of the walls are dry and smooth, only single coat of paint may be required to achieve the look and feel the drywall finish. The exterior surfaces of the walls can be produced with variety of finishes and surface treatments. Dukane Precast Company has used the double wall technique for the low-rise residential and non residential constructions. This company has built a plant geared for low cost production of roof and wall that created safest, durable and most energy efficient building systems. The double wall building method may offer significant energy conservation by recognising thermal mass properties. The benefits of double wall panels: The double wall panel design may be a good choice for the home buyers looking primarily in cost, comfort, health benefits. The high degree of insulation provided by the panels can permit the use of smaller heating and air conditioning units, thus may save monthly operating costs of the house. (Concrete Products Staff, 2002) 6.3 Floors/Roof Panels: 6.3.1 Hollowcore Floors: Hollowcore and prestressed floors are also commonly used as floor slabs in multi-Family housing, schools, and hotels, offices which may take an advantage of span to depth ratios, high load carrying capacity, fire ratings and speed of construction. The hollow unit reduces the self weight of the slabs. These floor units may be available in 1200mm in widths depths from 110 to 400 mm. The hollow core slabs for the residential buildings may have very good span capabilities (short long span). The long span is used for the car parks and office constructions and they can exhibit upward cambers. The short spans can also be provided with a layer of the expanded polysterene on the soffit to provide the insulation for the ground floor situations. The hollowcore slabs with reinforcement can be generally 225mm deep and 1200 mm wide Termodeck Company is more specialised in providing hollow core units. (Borghoff.M, 2006) The hollow core wall panels can be installed with or without insulation. The floor units can be provided with the polysterene or poly-isocyanurate (PIR) insulation material. The benefits of using hollowcore floor units are as follows: It may include high load carrying capacity, long spans, durability, erection speed, providing instant working, and very good thermal and sound insulation, providing the floor with fire resistant properties without the need for the fire protection treatment. Hollow core units may be the ideal building material for the construction of ware houses, manufacturing plants, schools, retail stores, office buildings and administration buildings. The use of pre stressed hollow core units and the solution which may enables fast construction and it is cost effective because the secondary fire resistance treatment is not required Precast hollowcore floors are designed with up to 4 hours fire resistance by using tabulated data that gives minimum dimensions for the depth of concrete cover to the prestressing strand or wires as well as overall depth of the floor slab to be used. (Norman E Brown, Head of Engineering Services ââ¬â British Precast Secretary ââ¬â Precast Flooring Federation) 6.4 Transportation: The precast concrete panels can delivered to the site over the highways by semi trailer trucks. A few can be shipped by rail or other modes of transportation depending upon the feasibility of resources. The precast plants may not restrict the size and weight of the precast panel production if there is ease of transportation. The use of light weight aggregate concrete panels can minimize the impact of weight on shipping, handling and

San Jose Museum of Art :: essays research papers
The San Jose Museum of Art is nicely decorated and furnished museum with many different types of art. I decided to start out by looking at some of the various paintings. There were many different kinds, including traditional oil paintings on canvas as well as ordinary paper. One that stood out in my mind was ââ¬Å"Desert Restaurantâ⬠by John Register. Itââ¬â¢s a painting of the inside of a diner sitting in the middle of an open desert. The picture gives an eerie sense of isolation. One sculpture that I remember was one by Oliver Jackson, which is untitled. The sculpture appears to be a figure of a human squatting down. The sculpture is made out of Steel, Marble, and Crayon. Besides these, there were many other interesting pieces of art in the Museum including the unique bright chandeliers made of blown glass. I read an article in an old issue of ââ¬Å"Art in Americaâ⬠about the lack of interest many young Americans show toward art in recent years. The article went on to explain how museum attendance was down in most museums compared to 20 years ago. Their main reasoning for this was the basic arguments of the advances in other forms of technology such as Television and computers that draw the attention of young ones away from traditional arts such as museums and live plays. The article went on to say that plays have become more for the highly sophisticated and less for the average person. The average person views a live play as any normal television show and doesnââ¬â¢t recognize the culture aspect attached to it. (Art in America, ââ¬Å"Fading Cultureâ⬠1991, 12-14) The San Jose Museum of Art held a lot of interesting types of art, but I think I can understand what the article I read in ââ¬Å"Art in Americaâ⬠was saying. Art has not changed much over time. Art takes a higher level of appreciation and educational level to be truly understood and enjoyed.

Pheromones :: Biology Essays Research Papers
Pheromones Have you ever wondered how different species know when to mate and who to mate with? How can they tell the difference between someone of the same sex, much less whether another organism is of the same species? This can be answered by chemical signals kn own as pheromones. Pheromones are unique and highly specific chemical signals produced by an organism that signals its presence to other members of the same species. Each organism have different pheromones they release during mating that helps them to id entify each other and start the process of mating. Pheromones come not only in forms of sex attractants, but also as alarm pheromones, aggregation pheromones, and dispersion pheromones(1). How do we know that such a chemical exists in organisms? In 1956, German scientists were able to identify the first ever pheromone in silkworm moths. After 20 years of research and over half a million female moths later, they were able to extract a pecu liar compound from certain glands located on the tip of the abdomen. When even a small amount of this substance was exposed to male moths, they would begin to beat their wings madly in a iflutter dancei. This indicated that they had detected the powerfu l sex attractant from the females that caused this type of behavior. After extracting extraneous matter and purifying the substance, scientists ended up with the first ever chemically pure pheromone. Since then, various other organisms have been studied and more is understood about the effects of pheromone, but not much is known about how pheromones work in more complex vertebrates such as humans. The next logical question to ask is how are these chemical signals recognized? Studies have shown that pheromone is first recognized by the chemical receptors in the vomeronasal organ (VNO) and olfactory bulbs located in the nose; signals are then sent t o the hypothalamus of the brain. In an experiment conducted on virgin male mice where their VNO was removed, the mice were found to generally not mate with receptive females, even if the maleis olfactory nerves were not damaged. This showed that the VNO s are needed in order start certain chains of reactions already programmed in the brain. Further studies show that when male mice have begun to associate sexual activity with other cues from females, including smells they become less dependent on the VNO s.

Tuskegee Airmen Essay -- American History Military Air Force
On July 19, 1941 the U.S. Air Force created a program in Alabama to train African Americans as fighter pilots(Tuskegee Airmen1). Basic flight training was done by the Tuskegee institute, a school founded by Booker T. Washington in 1881(Tuskegee Airmen 1). Cadets would finish basic training at Tuskegee's Moton Field and then move on to the Tuskegee Army Air Field to complete his transition from training to combat aircraft. The early Tuskegee squad were taught to fit in with the famous 99th fighter squadron, tagged for combat duty in North Africa. Other Tuskegee pilots were commissioned to the 332d Fighter Group which fought alongside with the 99th Squadron based out of Italy. By the end of the war, 992 men had completed training at Tuskegee, 450 were sent overseas for combat . During the same time, almost 150 died while in training or on combat missions. Additional men were trained at Tuskegee for aircrew and ground crew. The Mustang pilot spotted the string of Bf-109's heading toward the crippled B-24. The pilot, a Lt. Weathers, dropped his wing tanks, and turned into the German formation. He gave the leader a burst with his .50 calibers and it nosed up, smoking, and soon went hurtling down to the ground. The pilot radioed the others in his flight and heard "I'm right behind you." But when Weathers looked back for himself, all Page 2 he could see was the nose cannon of another Bf-109, pointing right at him. He dropped flaps and chopped throttle, instantly slowing his Mustang, and the Bf-109 overran him. A few bursts, and Lt. Weathers had his second kill of the day. Two more e/a were still in view and seemed like easy pickings, but the voice of the Group CO echoed in the pilot's mind, "Your job is to protect the bombers a... ...). Luke Weathers' escort mission described above provided the group's only aerial victories for the month of November. They flew 22 missions in December, running the group tally to 62 confirmed air-to-air victories by year's end. Bad weather in January limited them to 11 missions, picking up to 39 in February, but without many aerial victories. On March 24, 1945, Col. Davis led the Group on the longest escort mission ever flown by the Fifteenth Air Force, a 1600-mile round trip to the Daimler-Benz tank works in Berlin(Tuskegee Airmen 5). On this mission, Roscoe C. Brown, Jr., Charles Brantly and Earl Lane, each shot down a German Me-262 jet fighter aircraft. The Group received a Distinguished Unit Citation for their achievements this day(History 4). The Tuskegee Airmen continued flying and fighting, killing and dying, until the end of the war in Europe in May, 1945.

Essay Question: Within the period from 1450-1800, compare the processes (e. g. political, social, economic) of empire building in the Spanish Empire with the empire-building processes in ONE of the following: The Ottoman Empire OR The Russia n Empire. CC Essay #1 (3RR) Between the years 1400 and 1800, new empires appeared on the globe. One of these empires is the Spanish and the other is the Ottoman Empire.Both of these bear similarities but had their differences as well. They both carved out major chunks of the globe and were both major powers in the newly formed global world. Politically, economically, and socially, these empires were similar in many ways, but they had important differences that separated them apart. The Spanish were an up and coming world power in this time period between 1400 and 1800. They soon dominated overseas and trading. Differing from the Ottoman Empire to the east. The Spanish Empire was largely sea based.Their advanced ships and naval technologies allowed the to discover new continents and claim them to be their own. The Spanish set up colonies for the economy to run and they relied heavily on imports from their distant colonies across the Atlantic. They imported large amounts of silver and food goods to run their economy. Also, the foundation of their empire was primarily focused on the spreading of Christianity. They founded the Americas on their slogan ââ¬Å"Gold, God and Gloryâ⬠as they forcefully converted the natives in the New World.Also, their government was based on a monarchy with lesser nobles beneath him. The Spanish completely opposed the Islamic religion which can be seen it the Spanish Inquisition as they fought the Moors in Spain to make it purely Christian. The Ottoman Empire holds many differences against the Spanish Empire. Unlike the Spanish, the Ottoman Empire as a land-based empire that dominated the Middle East right up to Eastern Europe. The economy of the Ottoman Turks was based on conquering new lands and exploiting them for their value.The Ottomanââ¬â¢s continued to conquer, not only so their economies wouldnââ¬â¢t fall but also to spread their religion, Islam. Unlike the Spanish, they did have some religious tolerance in their e mpire, but hey mostly forcefully converted who they conquered The Ottoman Empire was an ethnocentric one, not open to too many outside ideas. The Empire was reigned over by a religious leader know as the Sultan, but his advisors, or the viziers were the rue voices of the government. They made those who didnââ¬â¢t covert to Islam their military or the janissaries, unlike the Spanish who just enslaved or killed them.Though having many differences, the Spanish and the Ottoman Empire were actually quite similar. Both were ruthless empires that conquered and dominated. Also, both empires wouldnââ¬â¢t have been established if it wasnââ¬â¢t for the desire to spread their religious beliefs and they both persecuted if necessary. Both of the empires had a lowe class of slaves or serfs that did all the work to maintain production and they both participated in the slave trade out of Africa. The governments of the Spanish and Ottoman Empire were run by religious icons or figures who had absolute control.These empires were among the wealthiest in the world, but only the elite had the money. The economy of both the Spanish and the Ottoman Turks both would not prosper if they had not conquered in the first place. Politically, economically, and socially the Ottoman Empire and the Spanish Empire were similar in many ways. The Spanish and the Ottoman Empire, one dominating the sea and overseas, one dominating the land, were politically similar in governing system, but different tin the way the distributed their policies.Economically, they differed in that the Ottomanââ¬â¢s relied on conquering and the Spanish on colonies but were similar in that they both needed to take over lands that werenââ¬â¢t originally theirs. Socially, the class system was rough and rigid in both with slaves at the bottom and absolute rulers at the top but they differed in the religion that was part of life in the two empires. Both empires would eventually see their downfall but for the tim e period 1400 ââ¬â 1800 they made their time worthwhile, similarly and differently.CC Essay #2 (3EE) European colonialism had an enormous impact on the world, then and today. What most tend to overlook, however is the empire of Russia, simultaneously rising in the east. In the 350 years after 1450, Spain and Russia built their empires, each with different locations, political structures , and goals. Spain, during this time period, was colonizing Latin America. A very small mother country, in relation to its colonies, was expanding greatly into weakly established tribal lands.The strongest threat, the Aztecs were conveniently naive and unlucky, leading to their fall, and the ultimately largely uncontested spread of the Spanish Empire. In Russia, however, strongly established nations bordered a large mother country. Russiaââ¬â¢s targets were its immediate neighbors. Russia needed careful diplomacy and established treaties and pacts to craftily add land to its empire, as opposed to Spainââ¬â¢s method of forceful takeover. Spain, in order to maintain control of colonies so far away, appointed officials to rule over designated areas and report to the mother country directly.The landlords in the new colonies, who employed forced labor of natives, had to report to the officials. This was called the hacienda system. The Russians, by virtue of the means which they used to add to their empire, were forced to grant more power to their local governments, leaving them nearly sovereign. The landlords, employing forced labor of serfs, had to report to their local officials, who in turn made their own decisions. Oddly enough, the Spanish colonial system, spread out over the globe, was more centralized than the Russian counterpart.The Spanish colonies were set up in such a manner as to yield the greatest economic benefit to the mother countries. Precious metals were exported in vast quantities to Spain, cementing Spainââ¬â¢s economic influence in the world market. Spainââ¬â¢s silver was especially valuable in China, who would soon only accept silver as currency. Cash crops such as tobacco, sugar and bananas brought more wealth to Spain and only served to make the colonies more dependent on the mother country to staple foods and supplies. Russia, however assimilated the newly acquired land into their culture.Northern Eurasia has very poor farmland and so the farther south Russia expanded, the more crops Russia could make available. Northern Russiaââ¬â¢s population could not support itself farming the dirt that the cold tundras provided, but the more warmer lands added to Russiaââ¬â¢s empire, the more surplus crop that could be sent north. The most valuable resource of Russiaââ¬â¢s empire was the vast numbers of people who could enlisted or recruited. Spainââ¬â¢s empire was meant to create wealth, while Russiaââ¬â¢s was meant to create power. Two empires, occupying the same time period, were as different as empires can be.Spa in had a spread-out, yet centralized empire governing forcefully conquered lands with the goal of creating great wealth, while Russia created her condensed, loosely organized diplomatic coalition of an empire, with the goal of accumulating power, should war become necessary. CC Essay #3 (3M) The Spanish and Otoman Empire were both involved in the process of empire building during the period of 1450 to 1800. Though both began to develop economically, politically and socially, their underlying strategies for this process differed greatly.The Spanish Empire followed and was helped along by the Catholic Church, while the Ottoman were a Muslim people that were governed by the Islamic religion. The differences between the Spanish and the Ottoman Empires stemmed from their very different religions, though the were both involved in global trade which made many of their developments similar. Economically, both the Spanish and Ottoman Empire had similar aspirations. During this period trade, as well as agriculture dominated.The Ottoman Empire, like the Spanish Empire cultivated their own crops and through importing received their needed goods on one of the developing trade routes such as the Indian Ocean route. However, the Spanish Empire during this period also began the process of widespread colonization along with the Portueugese. The Ottoman Empire began to conquer surrounding regions but was not a part of the major movement into the Americas. Both Empires, however, took part in the developing and growing slave trade during this period. The Ottoman especially used African slaves, as it was against the Islamic faith to use Muslim slaves.Economically the Ottoman and Spanish Empires followed very similar paths, though they differed significantly in their political structures. The Ottoman Empire based on Islam, and the Spanish Empire based on Christianity followed very different political paths. The Spanish Empire, for instance, began the process of colonization which m eant the use of administrators as bureus. The Ottoman Empire also moved into surrounding areas in the Middle East, though they favored a more centralized form of government. Also a crucial difference was that the Ottoman Empire followed the Islamic faith.This meant strict adherence to Islamic laws. Similarly, the Spanish Empire had no separation of church and state and received influence from the Catholic Church. This often meant that both political structures were dominated by a leader that was influenced by religious motives, rather than what was best for the state. This religious backing also produced a new practice for the Ottoman, the janissaries, or an army of Christian men taken as prisoners. The Spanish Empire relied on their own men to produce an army, such as the conquistadors which were used in colonization into the Americas.The major differences between the Ottoman and Spanish Empires politically was significant as were those socially. Socially, both empires saw signific ant influence from religion. For example, the Ottoman Empire followed the practices of the Islamic faith, and remained tolerant of other religions in their Empire. However, those that were non-Muslim were forced to pay a tax, but conversion was still not mandatory. The Spanish Empire was not as tolerant of other religions, and missionaries were widely used to convert others.Also in the Spanish Empire stratifications between those in Latin America and Spanish Europeans developed, along with colonization. The Ottoman Empire promoted relative equality among its people, as all were seen equal under Allah. Nonetheless, however, traditional ideas towards women remained the norm in both empires. Women were seen as child-barers and remained in the home, while in the Ottoman Empire some even were convened to the Islamic faith. Socially, as in other regions, similar developments occurred among the Ottoman and Spanish Empires in their social structure.The period 1450 to 1800 saw many developme nts in Empire building for the Spanish and Ottoman Empire. Though, like in all other empires, these were forced to go through the tedious work of building a social, political, and economic structure, one major difference existed. In the case of the Ottoman and Spanish Empires religion had the biggest effect on the paths that were taken in building empires. CC Essay # 4 (3 AA) The Spanish Empire and Russian Empires during 1450 ââ¬â 1800 were two different Empires with different goals in mind. The Spanish were more oncerned with overseas expansion, while the Russians were concerned with Westernization efforts. During 1450-1800 the Spanish were one of the leading countries in terms of overseas expansion. They were one of the first countries to have a representative sailor reach the New World. The reason for their great success in overseas expansion was the support the government had for it. The King and Queen payed for many explorations to new lands because they knew the fruit disc overy could bear. They were rewarded with new goods and new markets of trade.Soon, Spain began colonizing these newfound lands which benefited them even more. By colonizing lands rich with resources and commodities such as silk, gold, and silver, the Spanish made themselves the primary beneficiary. They were able to control imports and exports from these lands and open new trade routes. Also, in the colonies they made the citizens work for the prospects of Spain, for example searching for gold, or growing prosperous cash crops. The result of all this was that Spain was becoming increasingly powerful and spreading throught the world.The Russian Empire during 1450-1800 was one that was trying to establish itself as a world. Itââ¬â¢s leaders were focused using the ways of the West to promote itself. For example Peter the Great who greatly reformed Russia using Western European ideology. He rebuilt buildings, roads, and government systems. BY 1800 Russia, although not exactly a world power, had built itself up from its lowly state 400 years earlier. The major differences between the processes of Empire building between the Spanish and Russia from 1450-1800 was that Spain was already an empire to begin with which made it easier to grow.Spain was already powerful around 1450 while Russia was not. Therefore Russia and Spain had two different mindsets about building up their Empires. Russia was focused on establishing itself through reforms of government, architecture and other things. Spain wanted to expand its empire and did so by using their navy and by taking advantage of these newfoundlands. It was easy for the Spanish to colonize these new lands because they had superior weapons, tactics, and they brought diseases with them that killed off many of the native populations. CC Essay #5 (BBB)Within the period 1450 to 1800 the Spanish and Russian empires grew greatly. Both had changes in political structures, social structure, and economic structure. The political structure of the Spanish empire and Russian empire both changed within 1450 to 1800. The Spanish empire went from a monarchy to a democracy after having a few very bad kings and queens. The Russian empire went also from a monarchy to a democracy. This change also changed the social structure. As in most countries around this time the caste system was released and there was no more of it.With the change of the political structure also came the change of the economical structure. Spain along with Britain, France, and the other western countries, became westernized with factories and the new trade routes faster than Russia. The Russian empire became westernized later because, of course, they were very far away from the major technological countries. But as Spain did Russia became very westernized. The two empires were very similar and Russia seemed to follow in Spains footsteps.

Organizational Behavior Research Study Design Essay
This research question was chosen due to the proximity and significance of the results to our lives as university students under constant stress. Student stress factors include, but are not limited to: living on a budget, living away from family (international students predominantly), time issues relating studying and/or working, culture shock, adapting to a new country, climate, people. It may be particularly relevant to identify the role of extroversion in dealing with stress, for students may so take it as a way to reduce stress if extroversion proves to be effective. Even more so, if through the questionnaires a positive correlation between individualism and stress is observed, extroversion may serve as a coping method with stress, as it is expected that extroverts rely on people to feel good; if introverts rely solely on themselves to cope with stress, factors such as emotional stability (brain or personality anomalies or disorders) may play a crucial role in determining whether or not there is the possibility for individualism to exacerbate stress. The model below expresses the relationship between the variables. The independent variable is the individualism factor of cultures. The dependent variable is the stress factor The third variable is extroversion, which acts as a mediator in theoretically reducing stress in students from individualistic cultures.? Hypotheses Hypothesis: Extroversion has a positive correlation in the reduction of stress in students from individualistic cultures. Hypothesis 2: Introversion has a negative correlation in the reduction of stress in students from individualistic cultures. Hypothesis H0 = Extroversion plays no role in reducing stress in students from individualistic cultures. Methodoogy Design The survey sample method was the preferred of data collection is through questionnaires due to the convenience and readiness through which results can be attained. Each questionnaire is a personal and confidential paper with only the studentââ¬â¢s answers and nationality; only questionnaires with students from countries with individualism levels higher than 65 (according to the Hofstede scale) will be considered. The first questionnaire will be designed with the finality to discern between extroverts and introverts; it will consist of 15 basic questions about the personââ¬â¢s life setting, measuring their level of sociability and privacy. Later, they will be provided with a second questionnaire about the level of and how often they experience stress or positive moods, and will be measured by 20 questions about their life style and perception. These questionnaires will provide an overview of the level of stress experienced by extroverts and introverts. Questionnaires are not only cheap to administer, they also provide of insight on symptoms and emotions and the quantitative analysis thereof; however, the social desirability bias may jeopardize the objectivity of some answers, as well as the risk of some sensitive questions triggering specific reactions in students who might shape the answers. Sample questions can be found in Appendix 1. Data analysis Considering the many limitations in this study design proposal, with the potential large number of respondents, it was decided there is no representative sample for the statistical analysis of the questionnaires. The answers of the questionnaires will be translated to SPSS and due to the ordinal nature of the variables will allow for the data to be analysed through crosstabs and represented in bar charts, frequency tables and a scatter plot with a best fitting line. Reasoning and Evidence for Hypothesis Testing It has been inculcated that extroversion may be predictive of and is strongly correlated with, happiness (Costa, McRae & Norris, 1981). Headey, Glowacki, Holmstrom and Wearing (1985) argue this is conciliatory with extroverts experiencing more satisfactory life events with friends or at work. Additionally, previous studies suggested that good mood shows an increase in dopaminergic activity in several areas impinging of emotion and cognition; resulting furthermore, in a greater cerebral capacity to contrive stress. Since stress is as a negative emotional factor and good mood a positive emotional factor, this is supportive evidence that stress and good mood work in an opposing fashion; particularly with the observation that mental effects on the brain are reverse. Considering other studiesââ¬â¢ deductions, circumstantial and medical evidence, we are prepared to consider and accept extroversion as a strong indicator of happiness and therefore a mitigator of stress. Happiness is ordinarily perceived as the quality of oneââ¬â¢s life, the state of well-being, how much one likes life or, the degree to which one appraises live positively; the liking or positive appraisal of life may be stretched to the point of satisfaction, if high enough. However, the satisfaction with life is a mental state (constant or fleeting), but leaves doubts as to the nature of this mental state. The variance in interpretation and perception of concrete (words) and abstract (emotions) aspects among people is what precludes a conclusive result as to how can extroversion relate to happiness, the relationship between happiness and stress, and ultimately the point at issue that is if and how extroversion reduces stress. If happiness is positively correlated to extroversion and is negatively correlated with stress, we decided that measuring peopleââ¬â¢s extroversion may provide insight into their level of happiness which will allow us to infer into how efficiently they deal with stress. Putting it into a methodical perspective in accordance with our hypothesis; if a person belongs to an individualistic culture and is an extrovert, we expect them to have lower stress levels than people from the same individualistic cultural background who are not extroverts. This experimentââ¬â¢s design allows us to determine if extroversion does indeed reduce stress by hopefully identifying a pattern, and in case of such pattern, it will allow for grounds to further investigate other factors which may serve as coping mechanism for stress in ntroverts from predominantly individualistic cultures ââ¬âwhich makes this theory generalizable, considering environmental factors are known. Hypotheses Testing The hypotheses will be tested through the answering of the questionnaires. Each questionnaire will aim to gauge the level of stress, extroversion (introversion) and happiness of each student. The statistical analysis will assay how these aspects are interrelated and provide an empirical conclusion as to the effect of extroversion in the stress factor of students from individualistic culture. The correlation of the measuring aspects can help determine whether there is a significant positive or negative relationship between the measuring aspects. As stated in the first hypothesis, we expect a positive correlation between extroversion and stress reduction in students from individualistic cultures due to the relating determinant, happiness. Conversely, the alternative hypothesis is to evaluate the degree to which an opposite relationship exists, in the absence of a correlation in the first hypothesis.
