Polar Bear :: essays research papers

SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to -40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extending around the northern polar region. Necessities of Life-The polar bear eats mostly seals which he has to hunt. His trick is to wait by a breathing in the ice and when a seal comes up by that breathing hole, he grabs it so fast it knocks it unconscious and then he eats it. Other pray is a walrus calf or a musk ox stuck in snow, birds, eggs, fish, and dead whales. And sometimes in the summer it eats berries and grass. The polar bear has no water to drink so it only eats the skin and blubber, avoiding the meat. So by eating the blubber and leaving the meat the male bear is helping keep his body in balance with the surrounding environment. The bear would usually stay in a den or bury it self in the snow to avoid the suns ultra violent rays. Usually the pregnant female polar bear stays in the den.Food Chain-The polar bear finds its way on the top of its food chain. No predator on earth approaches the bear in size.

Polar bears are twice as big as lions or tigers, a typical adult male weighs half a ton and is five feet high at the shoulder. His paws are a fool wide. When he stands up straight, he can look an elephant in the eye.Explain- My species was endangered bad back in 1965 with no more than 5,000 left in the world.

Organization of the Police Department

Running a police department and preventing crime can be a complex task. Every individual within the police department including patrol officers, detectives, and clerical staff are vital in maintaining smooth order within the department and community. The organization of the police department is only effective when the officers know his or her roll and can fulfill the assigned duties based on the area, time, and purpose of the mission. The organization of the police department is what ensures an easy flowing and effective department. The organization does not just include the chain of command, but it includes how each officer will maintain order in the community by working different shifts and locations. Police officers can patrol the community in different areas known as beats or posts, zones, and precincts. A beat or post is generally a small area in which one or two officers can patrol by either squad car or on foot. The beat or post officers should be familiar with the people and businesses within the area, and also be aware of the risks and concerns in which officers may need to seek additional assistance. However, the beat or post area should be large enough to prevent boredom, but small enough to maintain with limited manpower (Dempsey & Frost, 2005). Next, a zone area within a community is when â€Å"a number of individual beats are grouped together† (Dempsey & Frost, 2005, p. 72). The purpose of zonal policing is to implement community policing, while providing a fast response time, performing visible patrols, and providing localized service to the community based on its needs (City of Windhoek, 2010). Finally, a precinct is an entire group of beats or posts in a specific area within a community. A precinct is used in larger communities with more officer manpower than a traditional small town. This keeps officers in assigned areas to ensure rapid response time and organization (Dempsey & Frost, 2005). Every police department across the world has to make good use of time and manpower to avoid stress and fatigue, and to ensure that more officers are on shift during the highest times of call volume. Police departments run on shifts that ensure that there are officers on duty 24-hours a day. Some departments may operate the three-tour system, whereas other departments may use fixed tours. The three-tour system uses three shifts a day that operates on either 8 or 12 hours per officer. Sometimes the shifts may overlap which can be used for additional manpower to patrol the community or used for training purposes. However, the numbers of officers may vary per shift due to the typical call volume every day. Some cities may experience a higher call volume at night; therefore, there is a need for a higher percentage of officers on the graveyard shift compared to the morning or afternoon shift. Additionally, the stress of the three-tour system can affect the personal life of the police officer and cause additional stress because the officer may work rotating shifts. Rotating shifts is when an officer may work all nights for an entire week, then the next week the officer may work the morning or afternoon shift to accommodate the three-tour system. The other type of shift, which is a fixed shift, is when officers are assigned to mornings, afternoons, or nights and usually maintain the same schedule. This option for the shift can be based on seniority; however, it does ensure that each officer gets adequate time for personal and social time (Dempsey & Frost, 2005). Another way to organize a police department is to place particular functions into separate groups to ensure a continuous flow throughout the department, as well as to prevent any confusion inside the department. The best way to keep the department organized is by grouping each job title together and keeping them separate from the rest. For instance, patrol officers should be grouped in the same unit, detectives should be grouped in another unit, and administration should be kept separate from these two groups. However, those are not the only groups within the department that should be kept separated. There are other positions such as juvenile, evidence, and communications that need to be secluded from other groups (City of Iowa City, Iowa, 2011). The purpose of each police department, however, is to ensure citizen safety by maintaining order within the community, enforcing state and local laws, as well as providing service to each member of the community (Dempsey & Frost, 2011). Although the tasks of the police department seem to be vast and complex, in reality each department is setup to provide organized service to the ommunity through careful planning of area, time, and purpose. Additionally, the way each police department is setup, it provides better service by ensuring that each area of the community is covered and that each officer has sufficient time to be relieved from duties for essential sleep, socializing, exercise, and family time. The planning and organizing of each department is as important as the protection and services that the department provides for each commun ity.

Running head: WHAT IS THE EFFECT OF LACK OF SLEEP ON A COLLEGE STUDENTS BRAIN AND BEHAVIOR Gilbert and Weaver (2010) examined the sleep quality with academic performance with university students, whether it is complete sleep deprivation or poor sleep quality. This study was to determine if lack of sleep or having poor sleep value in non-demoralized college students were related to the low academic routine. The author’s expectations were to find the relationship between the student’s environment and lifestyle with their sleep patterns and the force it has on their educational performance. Within the study the authors found that being able to have good sleep patterns and quality is a big key part for student to have a good GPA and†¦show more content†¦Cruess and Wells (2006) examined the results of sleeplessness on the consumption of food and food choices, which may have a lead problem to health in issues to those who have, sleep deprivation, The authors did this study to show the link between sleep and food intake within college students. They believ e that students who sleep less would choose them food that is less healthy, because the students are less concerned of their weight and more dependent on their mood and expediency. The authors expect to see more evidence showing that stress hormones are related with the relationship between sleeping and eating, which in other words, increases in stress lead to more snacking and a decrease in the consumption of typical meal-type foods (Oliver and Wardle, 1999). In their study they found that what they expected to find in the beginning had happened, in which there was a difference in food intake, measured by how much calories was consumed after the night of the students incomplete lack of sleep. The study also presented that there was a huge difference in food consumption and calorie intake on partial sleepless night and a normal night of rest.
