Obesity The Growing Rate Of Obesity - 2497 Words

Almost every country in the world has a similar problem: the growing rate of obesity in the population. Few may ask this question: what is obesity? Obesity is a condition characterized by a person’s excessive accumulation and storage of body fat. Millions of people around the world are affected by obesity, while hundreds of thousands of lives are claimed every year due to this preventable condition. We, as Americans, constantly blame fast food for our obesity problem. In my opinion, think it’s the opposite. Human beings have the free will to choose what we want to eat. No person on the face of the earth can force another person to eat what he or she chooses for the other.

The top five fast food chains in the U.S. (respectively) are: McDonald’s, Subway, Starbucks, Wendy’s, and Burger King. When it comes to popularity, without a shadow of a doubt, McDonald’s is the most popular fast food chain, not only in the United States, but also in the world. Some would assume that McDonald’s was the first fast food chain created. In reality, a fast food chain called â€Å"White Castle† was the first chain created in 1921. McDonald’s represents approximately 43% of all fast food restaurants in the United States. On the McDonald’s menu, the top 5 most ordered foods (respectively) are: their French fries, the Big Mac, a Snack Wrap, the Happy Meal, and the Egg McMuffin. McDonald’s, on average, feed more that 46 million people per day in the United States alone. For McDonald’s, customers who visit this restaurant at least 10 times a month make up around 75% of its sales every year. If one were to order from a fast food restaurant, just one meal alone would contain all of the c alories necessary for the entire day. Over the years the two main proteins used in fast food restaurants are chicken and beef. Portion sizes for chicken and beef continues to grow, especially in McDonald’s. America is taking it too far with fast food and their money. On average, Americans spend more than $100 billion on fast food every year. This would be

Television Does Not Burn Our Minds - 941 Words

When people generally think of television, most may assume it rots the mind. Freelance writer Rachel Krantz not only believes that TV is not useful for your mind, it â€Å"may kill you, decrease your chances of having kids, ruin the ones you do have, and possibly turn you violent.† Could any of this have happened to me as I was binge-watching The Simpsons from seasons one to eight during the summer? I initially thought that this show was prone to dumb me down as I did this, but instead it enlightened me through its clever writing. Even with gags as dumb as an old man hurt by a football thrown to his groin, I felt as if no other show was as thoughtful and full of heart as The Simpsons. Despite that Krantz’s claims are backed by academic studies and research on television, it should be the least concern for our minds. Television does not rot our minds; it intellectually challenges and aptly adjusts our minds depending on how we use it. The further time a kid spends watching television, the larger their brains grow. That seems great, although apparently this is considered unhealthy for them. A recent Japanese study reveals that as kids between ages 5 through 18 spend, on average, two hours of watching TV per day, certain areas of their brains were growing. The rise in brain volume of these kids was linked to a fall in their verbal IQ. However, the data in this study was not clear if TV watching caused this (Sanders).

Critique of the Theory of Assimilation - 1583 Words

The scholars of the Chicago School of Sociology have presented a theory of assimilation that generally states that people of different cultures and ethnicities that come into the United States (also applies to other countries as well) will have contact with American culture which will generate conflict. These people of a different culture or ethnicity will eventually acculturate and integrate into a so called â€Å"Melting Pot† of culture in which they will give off their own unique flavor but will eventually blend into mainstream society. I feel that this theory is quite eloquently constructed, but is rather limiting and not necessarily representative of every ethnic group that assimilated in the United States and should be broadened to†¦show more content†¦The Chicago School of Sociology’s theory of assimilation describes the way in which foreign cultures interact with American culture. From my understanding, the described initial reaction is unpleasant and c onflictual. I generally agree with this statement. It is true that when new cultures are introduced, people are a bit wary of their practices or appearances. To put it quite simply, people are uncomfortable with other people that act or look differently than they do. But with time people adjust and are able to become more comfortable over time as subtle changes are made in both parties. Since the abolition of slavery in 1865 with the passing of the Thirteenth Amendment African-Americans have been striving to be accepted as part of American culture. A main period of focus for African American assimilation and acculturation is from around 1955 to 1968 and is better known as the Civil Rights Movement. African American culture had already been defined very well by the Harlem Renaissance in the 1920s and 1930s. The Civil Rights Movement led to a better integration of African Americans into society. Most of the progress was made through nonviolent protests and civil disobedience. There we re setbacks to the progress that was often frowned upon by African Americans that desired progress. â€Å"I see negroes like him everyday, breaking into a goddamn buck-a-wing every time a white man come by.

Risk Management PCNet Project - Free Sample Assignment

Question: Discuss about theRisk Management for PCNet Project. Answer: Introduction The PCNet Project A PCNet project refers to a low-cost connection of computers which have been designed to support and manage a project centrally using network applications in an industrial set-up. Also known as a thin client, the PCNet lack a diskette drive and is designed in a manner that supports specific business tasks and application (Loch, 2005, 1). The project usually comprises of four main areas encompassing infrastructure migration. The PCNet project encompasses one of the several IT integration projects. The case study focuses on the role of PCNet and integration of the IT systems in the acquisition of RBD Inc., by the Metal Resources and how the latter would have managed the risks that threatened to cripple the firm. The Four Steps of Risk Management Hazard Identification/Risk Identification Undoubtedly, risk identification serves as an indispensable step in project planning. In this step, the concern of the risk manager is to recognize all the factors that may hinder the progress of the plan. That is all the factors that may serve to make a project suboptimal. Risk identification involves a thorough exercise before the preparation of the project organization to identify all the factors that may pose a threat to the project and identify the team that will best respond to such a risk. After the identification of the risks, the risk manager should organize/classify the risks into the four basic risk categories (financial risks, operational risks, financial risks, and hazards). While financial risks relate to the impact of market forces on the financial position of the firm, operational risks relate to any failure in systems, controls, and processes (CIOB Institute, 2016, 3). On the other hand, societal and economic forces give rise to strategic risks while hazards refer to risks arising from loss exposures due to the nature of the property. Risk Assessment and Prioritization Once the risk management team identifies the risk, it is important to understand the nature of the risk fully before commencing treatment. Faizul (2015, 1) argues that depending on the risks nature; a risk manager may adopt quantitative or qualitative analysis or a combination of the two techniques (notwithstanding several other specific techniques) to assess the risk. While qualitative analysis serves to establish the significance of the consequences of a specific risk, quantitative analysis assists in assigning specific values to the consequence of each risk and the probability of such a risk occurring to establish the level of the risk. After risk assessment, the risk manager should proceed to prioritize the risks based on the impact assessment to allow the project team to focus on the most significant risks. Risk Response Management It involves reducing the threat and exploitation of opportunities. After risk identification and assessment, the project team should proceed to modify the risks in a manner that serves to promote the companys objectives. It is worth noting that most risk may require multiple treatments. Some of the treatment techniques a company may adopt include avoiding the risk, transferring the risk, retaining the risk, exploiting the risk, and modifying the likelihood of the risk occurring and its impact. Risk Response Control Undeniably, workplaces often change as a result of the company purchasing new equipment and securing new employees. Consequently, the risk facing the project often change. As such, regular assessment and monitoring enable the project team in evaluating their current plan and adjusting the plan to suit the companys goals. Risk monitoring further enables a firm in identifying emerging risks and other risks not previously identified while they are still manageable (Crain, 2014, 4). The step further serves to provide quality assurance to the project team and the management of the company of the effectiveness and efficiency of the treatment techniques adopted by the project team.

Ocean Currents

Ocean currents are the routed movements of oceanic water which are constantly flowing within the ocean or on the ocean surface. An ocean current is created by several forces and elements that act upon a unit mass of water in the ocean and such factors on an environmental scale include the gravitational pull of the Moon and the Sun, wind, salinity levels, and the rotation of the earth, temperature and tidal waves. However, the two forces that create the most conducive conditions for a current to form are the Sun and the rotation of the Earth. Advertising We will write a custom essay sample on Ocean Currents specifically for you for only $16.05 $11/page Learn More Physical factors such as the depth of the ocean, contact with other currents and the composition of the shoreline will determine a current’s course and potency. Ocean currents are known to surge for great distances and the gravitational centrifugal pull of great currents round the earth ha s a pivotal role in influencing the global climate especially of islands and coastal regions. It is well know that the California Current makes the weather of the Island of Hawaiian to be cooler as measure up to other regions which are situated at the same latitude, the current is a tropical one leading to the sub-tropical climate of the islands. Ocean currents also determine the marine life of a region because they play a major role in determining the salinity of the water. Currents can carry a large volume of highly saline water for great distances and the marine life of the region where the water gets deposited can significantly be altered. There are different currents are flowing at different levels in the ocean and it is possible for two or more currents to flow through a single region simultaneously but at different levels. There are generally two types of ocean currents depending on the water level where the movement of oceanic water takes place and they are the deep ocean c urrents and the surface ocean currents. Deep ocean currents are mainly caused by the fluctuation in the mass of water and by gravitational forces acting in the deeper parts of the ocean usually below three thousand feet. Variation in temperature and the salinity levels of the water cause a change in the mass and volume of water leading to deep ocean currents. A submarine river is another term which is used to refer to deep water currents basically because the currents occur in the lower levels of the ocean. The deep ocean currents carry large volumes of water which flow the greatest distances leading to thermohaline circulation. The submarine rivers are at times responsible for transferring deep water plankton and marine life from one part of the ocean to another and also cause the vertical movement of water in the upwelling and down welling parts in the oceans.Advertising Looking for essay on geology? Let's see if we can help you! Get your first paper with 15% OFF Lea rn More On the other hand, surface ocean currents take place on the upper levels of the ocean and are commonly caused by air currents acting on the ocean’s surface. Surface currents are composed of about ten percent of the total water volume in the ocean and are usually limited to the upper one thousand three hundred feet of the ocean. Surface currents form the Ekman spiral effect which is the circular movement of ocean surface water at a given tangent relative to the prevailing air currents. The Ekman spiral effect is usually in a clockwise direction in the northern hemisphere and in a counter-clockwise spiral in the southern hemisphere due the alternate air movements inflicted. However, the Indian Ocean does not follow this rule due to the strong torrential rains and the atmospheric system in northern region of the ocean which alters its trend twice every year. The southwest torrential rain which occurs off the coast of Somalia is caused by the Great Whirl, which is a st rong current which has a circular motion. The currents on the ocean basin surface are normally asymmetric with the eastern currents flowing towards the equator and the western currents flowing towards the North and South poles. Such currents are majorly influenced by gravity, with the eastern currents flowing in separate extensive currents whereas the western currents for instance the Gulf Stream are relatively contracted. Deep water current movement patterns are formed through a complex process which begins with the freezing of the water in the ocean. Once the water is frozen, the salt in the ocean water is also condensed in the freezing process and this leads to the creation of a layer of cold salt concentrated water which forms near the surface of the water where freezing generally takes place. The brine then gradually sinks because of the density difference, brine being denser than the water below. The salt concentrated water is more viscous which makes it become denser than t he water around it. Consequently, the gelatinous salty liquid sinks, leaving the surface levels of the ocean and will only settle when it gets to a region in the ocean where it bears an equal density to the surrounding ocean water. This process is very prominent in the Greenland and Labrador Seas that are located in the Northern Hemisphere, and the Weddell and Ross Seas in the Southern Hemisphere. Similar to surface currents, most of the current movement takes place on the western sides of ocean basins except that deep ocean currents have their progression towards the north. Advertising We will write a custom essay sample on Ocean Currents specifically for you for only $16.05 $11/page Learn More Surface currents flow in a succession of nearly circular gyres in the ocean basins. Most of the gyres are located in the western regions of the globe where the currents are contracted and carry large volumes of water for example the Gulf Stream, Agulhas and Eas t Australian Currents. The oceanic and atmospheric gyres help to move heat generated in the equatorial regions towards the poles. The polar movements of the ocean currents constitute the northward warm water current in the North Atlantic and in the North Pacific and the southward flow through the East Greenland and Labrador Currents. The surface currents that flow towards the equator move alongside the eastern edges of the gyres and are usually cooler than the currents that flow towards the poles located on the western margins. Air movement causes upwelling and provides the requisite wind stress towards the equatorial region moving water away from the coast and gravitational force pushes cooler subsurface water to replace the unoccupied water spaces. The Southern Ocean region experiences persistent westerly air movement leading to the Antarctic Circumpolar Current, a constant circumglobal current which hinders the formation of gyres. The Antarctic Circumpolar Current allows for th e integration water from different ocean basins making it the largest current on earth. Sverdrup (Sv), is the standard unit used to measure ocean currents with one Sv being equivalent to a volume flow rate of one million cubic meters per second. The equatorial region experiences little or no gyres and currents here are usually surface currents stirred by the trade winds that originate from the eastern regions of the Northern Hemisphere and the Southern Hemisphere. The North and South Equatorial Currents which move toward the west are formed by trade winds which lead to an upwelling along the equator due to the movement of the southeast trade winds across the equator. Furthermore, the equatorial region does not incur Coriolis force which is potent even with a one degree shift north or south of the equator. The Doldrums region is formed in the equatorial region where the northern and southern currents border. The Doldrums region is generally permeable to the Equatorial Countercurren t water that flows back eastwards since the water would otherwise get concentrated on the western boundary allowing the doldrums region to act as an outlet. The velocity of the currents also varies, with the western currents moving faster than the eastern currents.Advertising Looking for essay on geology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Marine life in the oceans is totally dependant on ocean currents for survival. Oxygen derived from the atmosphere is mixed with water through the flux of surface water like waves which are more or less generated by surface currents. For the oxygen to be delivered to the organisms, the oceanic currents and welling are needed to translocate the oxygen to all tiers of the ocean. Furthermore, marine victuals for instant phytoplankton which are minute organisms that are primary in the marine food chain are distributed in the ocean through the ocean currents. The organisms are usually caught in the currents and transported for great distances before being deposited in an ecosystem where they establish sustenance. Therefore ocean currents play an important role to both shallow and deep water organisms because they push food into the organisms’ environment. Surface organisms such as crabs are also reliant on the currents which carry microorganisms from the oceans and deposit them n ear the shores. In addition, currents provide inimitable signals in the life cycle of almost all marine organisms through transport of subtle chemical indicators. Turtles for instance migrate for long distances to mate and the precursor to their migration is the sensing of chemical triggers produced by sources that are more than a thousand miles away which are transported by ocean currents. Warm water used by marine life such as fish and turtles to incubate their eggs is deposited to the nesting grounds through ocean currents. Physical features such as lagoons are put together through the ocean currents which carry marine particles that are then deposited onto the lagoons leading to the expansion of the ecosystem. Due to the fact that ocean currents can move for great distances, they are also likely to spread out toxins in the oceans. For example, DDT which was a deadly insecticide was commonly used in America in the mid twentieth century. Through deltas, slight concentrations of the insecticide were moved to the ocean. The eventual consequence was that the product was found in penguins in both the north and south poles which had led to the thinning of the penguin egg shells. The only possible reason as to how the insecticide moved to such great distances is through ocean currents.
