Teenagers and Stress essays

Teenagers and Stress essays Stress is a feeling that's produced when we react to certain events. It's the body's way of rising to a challenge and preparing to meet a tough position with focus, strength, determination, and heightened alertness. Stress among teen has become a growing epidemic in the past century, Teen stress is more common than you may think. Teens fall victims to stress everyday whether some people would like to think so or not. Its a point of a child life where some may say its the most stress that anyone will experience. Its the time where there about to be on their own, they have huge decisions to make about their future and their goals, and what they are going to do with their life whether if to do with their education, work and even personal life. With all the peer pressure and struggles that teens may face, can have a huge effect which can put a huge load of stress on to a teen. Stress in teens is simple to identify such as depression, sleep deprivation, internal clock may be out of whack . However teen stress must be addressed right away (Arenofsky). A major factor that can bring stress upon a teen is school related. Many may believe that school is happy place where stress is hardly to be seen, but unfortunately this is not the case. School is one of the most stressful experiences a teenager will ever endure. Its the time when they are finding themselves personally and who they are. They seek desperately for acceptance whether if its for the good or bad. Some times this can place teens in a bad position, because they might get accepted into the wrong crowd of people and be peer pressure into things that they wouldnt normally do themselves, just to get that feeling of being wanted or accepted. Also another reason school plays an important role into stress, is that teens and push and lecture daily by their parents and fellow teachers and administration to be that honor student that exceeds in everything ...

SNPs, Chips, and the essays

SNPs, Chips, and the essays Single nucleotide polymorphisms (SNPs) are DNA sequence variations that occur when a single nucleotide is altered. A SNP might change the DNA sequence from AAGGCTAA ATGGCTAA. SNPs occur every 100 to 300 bases. SNPs can occur in both coding and noncoding regions of the genome. Some SNPs have no effect on cell function, but others can have a major impact on how humans respond to disease and drug therapies. This makes SNPs of great value for biomedical research and for developing pharmaceutical products. SNPs also do not change much through generations, making them easier to follow in population studies. Scientists believe SNP maps will help them identify the genes (there are many genes involved) associated with such diseases as cancer, diabetes, and some forms of mental illness. SNP maps are also expected to identify thousands of additional markers along the genome. Over the past several years, a new technology called DNA microarray has attracted enormous interest among scientists. A microarray is a tool for analyzing gene expression that consists of a small membrane or glass slide containing samples of many genes arranged in a regular pattern. This technology can monitor an entire genome on a single chip so that researchers can have a better picture of the interactions among thousands of genes. Microarrays may be used to assay gene expression within a single sample or to compare gene expression in two different cell types or tissue samples, such as in healthy and diseased tissue. Only a fraction of an organisms genes are turned on. It is the genes that are turned on, or expressed, that gives the distinctive properties to each cell type. A microarray works by allowing mRNA molecules to hybridize to the DNA template from which it originated. By using an array containing many DNA samples, scientists can determine the expression levels of hundred s or thousands of genes within a cell by measuring the a...

Operations Management in Southwest Airlines Essay

Operations Management in Southwest Airlines - Essay Example Southwest Airlines is an example for all of us because it has made tremendous progress by using techniques to improve upon its operations management. It is using its operations management to achieve competitive edge over its competitors. The company uses techniques like e ticketing, faster between flight services, increasing number of seats in planes, flying shorter routes, efficient service of planes, more flight hours by pilots, unique hiring method, and preparation before starting new flights, and less waiting time for planes in order to achieve competitive edge over other airlines.E-Ticketing Southwest Airlines was the first airline in the world to use e-ticketing way back in 1994 (Air Treks, 2011). This initiative of Southwest Airlines has helped them a lot in saving costs related to paper. Also e ticketing has decreased the time required for passengers to board the plan and due to online ticketing checking time of passengers have decreased significantly. All these are the benef its of e ticketing.The company also encourages passengers to use e ticketing because of the advantages of this service. Customers are also charged a nominal fee for the service so this is a win win situation for everyone. Being the pioneer in e ticketing the company has also earned a reputation of serving its customers in a better way by using technology. The clerical work is also highly reduced by issuing tickets online. The system does all the work reducing the number of employees needed for the ticketing purpose. Paper tickets would take physical work as well so that is why it is not desirable. The cost effectiveness of Southwest Airlines is preserved in this way. Southwest Airlines flies domestically only so it is very important that it offers quick services to its customers. Mostly domestic flying passengers are in quite a hurry and that is why e ticketing compliments the clientele of Southwest Airlines. Passengers can book their flights before coming to the airport. By using e ticketing the company has increased efficiency of its operations. Between Flights Time Another operational method used by Southwest Airlines to increase its cost effectiveness is less time taken between flights. By decreasing time between flights Southwest Airlines fly more flights in a day. The time between flights is decreased by quick cleaning services and faster checking out of passengers. Southwest Airlines is famous for quick boarding and off boarding of passengers. Passengers are immediately off boarded as soon as the plan reaches the desired destination. This allows planes to fly more than other competitors in a day. Employees at different
