Social Security Number Allocations by Location

The first three digits of a persons Social Security number numbers can often help you to determine where your ancestor may have possibly been living when his/her SSN was issued (see exceptions below). These numbers can also be helpful in determining which listings in the SSDI may belong to your ancestor. The first three digits of a persons Social Security number were, prior to 1973, determined by the state where the person applied fo their social security card. Since that time, the first three digits have been assigned based on the ZIP Code of the mailing address on the Social Security number application. The chart below shows the first 3 digits of the social security numbers assigned throughout the United States and its possessions. SOCIAL SECURITY NUMBER STATE CODES * The same number, when shown with more than one area, means that certain numbers have been transferred from one State to another, or that an area has been divided for use among certain geographic locations.

The Effects Of Television On Children s Brain - 1039 Words

The Effects of Television on Children Television sets can be found in almost every American’s home. They’re used for news report, daily weather forecast and for pleasure. However, time spent in front of the tube is linked to having adverse affects in the development of children’s brains. Excess screen time can be linked to attention deficit/hyperactivity disorder, aggressive behavior, poor mental development, and physical health issues later in life. In one study a young six year old boy was observed after being referred for aggression disorders in school. The observation found that he was watching three to four hours of television programming a day. When his mother would try to cut down on this time he would lash out and become very†¦show more content†¦Plus, when watching TV you’re not interacting with others. This lack of interaction leaves little opportunity to develop imaginative ideas. Without this kind of creative thought the child cannot b egin to strengthen their mental problem solving skills. A child’s ability to focus their attention on any given subject also seems to be under television attack. â€Å"The rapidly changing images and scenery of many television shows may over stimulate very young children and adversely affect the development of brain synapses,† (Lehman 14). As previously stated, television programs can cause over stimulation of the brain. This is not a good thing. Being flooded with stimuli inhibits the brain’s ability to focus on any one idea. This affects the child’s ability to contemplate deep thoughts, comprehend lessons, and participate in independent problem solving (Healy 917-918). Another troubling area concerning television at a young age is something referred to as ‘background television’. This is television that a child may be too young to comprehend and plays in the background during play, family time, chores, etc. The American Academy of Pediatric s, Committee on Public Education (1999) recommends no screen media exposure for children aged 2 years and younger. Nevertheless, nearly 75% of parents of very young children say that television is on ‘‘about half of the time’’ or more, even if no one is watching (Rideout

Business - Government Regulations and Society

Question: Discuss about the Business, Government Regulations and Society. Answer: Introduction: Large corporations and business industries influence economic, environmental, cultural and political forces, which are the key components to shape our world (Roach, 2000). In the past, the size of these industries was not too big and they were controlled by the actions of the society. With the globalization, the industries have moved towards becoming more powerful. Though, there is not any widely accepted metric to measure the power of corporations to shape our world, the fact that they affect the world in an imperceptible and complex manner cannot be avoided (Korten, 2015). The actions of these corporations shape our consumption patterns, working schedule, income distribution, communication, culture, transportation and even the political situation largely (Serafeim, 2014). Facebook, one of the biggest corporations, has almost swallower the public sphere of journalism industry. It has become more powerful in controlling the publication matters and grabbing the attention. Social media companies like Google, Apple, Amazon, twitter have changed the thinking pattern of the entire world largely (Korten, 2015). These corporations affect the society as completely, even those who are not directly associated with them. The industries generate pollutions, which affects all the nearby residents. These corporations are responsible for many other externalities (Roach, 2000). However, the corporations and industries sometimes use their power to avoid their responsibility of compensating for the significant external costs. They also use their power to shift these externalize cost to the public sector. Through the power, they are successful in reducing the applicable tax rate and receiving substantial subsidies (Serafeim, 2014). The corporations and industries possess huge wealth and political power. They exert this power in influencing international trade agreements. The laws governing the business world are also relaxed for industries and corporations. These corporations enjoy greater freedom and rights than that of the individual (Korten, 2015). For example, the metastasized growth of Wal-Mart has become so influential that it has knocked out many local businesses and transformed the logistic industry dramatically. In a way, they set their own rules. Although the influence of corporations on world is not new, but the rising size, wealth and thus the power is a matter of concern. These may result in corporate libertarianism along with libertarian economics and market capitalism (Serafeim, 2014). However, the corporations also use their power to address the social and environmental causes. They spend their resources on many issues that are immaterial for them. These corporations have recognized a shifting role in the society. They even frame various social and environmental policies to integrate in their business operations. Corporations use their power to develop a relationship between business and society and satisfy the needs of all its stakeholders. Various internal and external forces need to be anticipated and recognized for the growth and prosperity of the businesses (Harrison John, 2013).. These forces have changed the management task, altered the business operations and modified the stakeholder expectations. The main task of the management is planning, organizing, controlling and leading. The internal and external factors and the business environment affect all these functions. The managers must try to identify these forces to take best advantages of these forces (Isaac, n.d.). The impact of these forces on the management task is discussed below: Human resources require managers to be alert while recruitment and selection. Organizational culture requires managers to develop and maintain positive attitude of staff members. Organization structure affects the division of labor to accomplish a task. Financial strength affects the implementation of strategy by the management. Sociological and demographic factors influence the management task of planning and designing the products for specific groups. Prevailing economic and political forces affects the spending patterns of consumers. The managerial decision should be effective to succeed in the dynamic market environment. Technological forces now require managers to be flexible to adapt the changes. Market forces require managers to make strategies to deal with the constantly changing environment and the competitors. The legal forces like taxation and other industrial and workplace legislations require prompt management actions (Harrison John, 2013). These forces also affect the business operations. The internal forces are within the control of the company to an extent but the external forces cannot be controlled (Li Liu, 2014). The influence of the forces on business operations are: The strength of the employees affects the performance level of the organization. Strategic risk affects organizational ability to achieve their business objectives. Companys location affects the ease of procurement and distribution. Access to natural resources reduces cost of operation. The economic condition affects the demand for the products and thus the sale of the products. Technological changes determine the production and distribution manner. Environmental fluctuations influence the availability of the resources. Socio- cultural forces influence the buying pattern and expectations of consumers (Li Liu, 2014). Stakeholders have the greatest interest in the business operations (Rothaermel, 2015). The change in the internal and external forces of the business environment has also modified the expectation of the stakeholders. The working condition influences the performance and behavior of internal employees. Technological changes have raised training and development expectations of employees in order to stay updated. The rising competition has raised customer expectations of quality products at reasonable cost. The legal forces have raised the demand for healthy environment, good corporate governance practices and concern for corporate social responsibility (Richards, 2016). It can be concluded that various internal and external forces have a direct impact on the task of the management, business operations and expectation of the shareholders. Law and government regulations supervise the business behavior towards beneficial direction throughout the world. Government implements and enforces laws and regulations, in the absence of which, the businesses might engage in unfair and unethical practices and produce outcomes that are unacceptable (Breslin, 2016). Government regulations protect the interest of stakeholders by reducing objectionable business activities. The legal regulations establish an expected performance standard and failure to comply with the standard brings consequences in terms of fine and several other penalties. It promotes the compliance of corporate governance, both through encouragement and coercion, which in turn reduces the incidence of illegal behavior (Breslin, 2016). Government establishes explicit legislations to restrict illegal activities and fair compliance of the ethical obligations. The government regulations also monitor anti competitive practices and supervise the position of dominance. Government regulations also monitor business behavior towards the environment (ernstein, 2015). It rewards the companies with green awareness and environment friendly practices and imposes tax for wasting energy. Government regulations ensure that the new firms can enter the market without any restriction unless otherwise the law itself imposes a restriction. It allows firms to exit from the market freely in case it chooses to do so (Breslin, 2016). The government regulations control the price level ensuring that the organizations charge a fair price. They also monitor the prevailing wage rate and fix minimum wage level. The government regulates the standard and quality of certain products and services. These regulations enforce the complex business contract as to the mergers and acquisitions. It also protects the consumers by ensuring that the vendors meet their obligations. Legal regulations protect the employees of the company by administrating the health and safety measures of the company (ernstein, 2015). Government regulation ensures non-discrimination and fair recruitment and hiring process. It also provides for privacy of the sensitive information of the employees and customers (Holt, n.d.). Thus, it can be said that the law and government regulations have a significant role in monitoring and supervising the business behavior to generate the desired results for the betterment of the society (Breslin, 2016).

Was the Operation CHROMITE concept sound manoeuverist logic essays

Was the Operation CHROMITE concept sound manoeuverist logic essays Was the Operation CHROMITE concept sound manoeuverist logic justifying General MacArthur's resolute determination and acceptance of the inherent risks, or was success attributable more to his intuition and good luck? General Douglas MacArthur was the architect of the victory at Inchon, he was a 70 year old veteran of both world wars and was at the time Commander in Chief, Far East (CINCFE) Theatre. He was responsible for formulating a response to the North Korean invasion which had begun on 25 Jun 1950, as you have already heard his response was Operation CHROMITE. In the next 15 minutes I will attempt to focus on MacArthurs role and vision and answer the question as to whether it was his determination and acceptance of risk that led to the victory or more simply his intuition and good luck. I will look at the background, the plan, briefly look at the operation itself and then draw conclusions. Throughout I hope to link back to the five key areas of this question: manoeuverist logic; determination; risks; intuition and good luck. In Jul MacArthur had large numbers of troops commited to holding back the N Koreans however he had realised that a decisive solution to the conflict was needed. Having seen the South Koreans retreating he stated he would rely upon strategic manoeuver to overcome the great odds against me. It would be desperate, but it was my only chance. With the war a little over a week old he had instructed his COS, General Edward Almond, to consider plans for an amphibious operation to strike the enemy centre of communications at Seoul, an indirect appraoch designed to shatter enemy cohesion. Mac Arthur never wavered from his commitment to Inchon despite a number of postponements. The North Korean Army had forced the combined Republic of Korea and US forces to positions on the southern tip of the Korean Peninsula, a distance of some 150 miles. To stop this MacArthur had had to use every ava...

The List of All U.S. Colleges With a Modern Languages Major

If you are interested in learning another language and increasing your understanding of a foreign culture, a modern language major could be the track to a fulfilling college experience and an array of interesting career paths. Keep reading to learn the reasons for studying modern languages, gain insight on what it takes to get into a top program, and see a comprehensive list of all the U.S. colleges with a modern languages major. The simplest reason for studying modern languages in college is that you’re interested in learning more about the world in which you inhabit. Languages considered for a degree in modern language are French, Spanish, German, English, Russian, Chinese, Arabic, and Japanese. More than learning how to speak and write a language, modern language majors gain an understanding of language as a system and its function within a social context while also learning about the culture, media, and politics of the regions that speak it. Â   The ability to effectively communicate with people with a different language and cultural context is becoming an increasingly valuable skill in a more globalized world. Graduates with a degree in modern languages are natural fits for positions as interpreters and translators, consultants and relations specialists for international businesses and tech developers, and in education. The median annual income for interpreters and translators in 2018 was $49,930 according to the Bureau of Labor and Statistics (BLS), which is slightly higher than the average national salary. The BLS also projects an abundance of opportunities in the future for interpreters, as they anticipate 18% growth in the field—more than twice as fast as the national average. Another good reason to study a foreign language? A Wharton and LECG Europe study found that studying a second language is correlated with about 2% more in annual income. In addition to being equipped for a language-related job, students studying modern languages also graduate with a host of skills that easily transfer across industries. Modern language majors are adept at communicating, adaptable to different situations and people, and multi-taskers. Learning a new language also makes students more aware of the use of their native language—making them better writers, speakers, and conversationalists. The ability to speak a second language makes a student more employable by helping them stand out from a field of applicants—this is especially true in globalized industries. Only about 10% of the U.S. population is multilingual—for comparison, in Europe, 52.7% of the population is multilingual—meaning when applying for a job there is a strong chance you’ll be the only multilingual candidate. In fact, a study by The New American Economy shows that between 2010 and 2015, the demand for bilingual workers more than doubled—going from 240,000 jobs to 630,000. No different than students hoping to study engineering, chemistry, or history, students seeking admission into top schools to pursue modern languages will need a robust college profile. One of the best ways to attract the attention of admissions officers is to maintain a strong GPA, high class rank, and show a willingness to challenge yourself academically by taking advanced courses, particularly in language and the humanities. Another fantastic way to stand out amongst a crowded field of applicants is through your extracurricular activities. Participation in your high school’s foreign language club, volunteering in a community where English is a second language, and tutoring are all tremendous ways to demonstrate an interest in a foreign language outside of the classroom. But don’t forget to highlight any interests outside of language as well! Sports, music, art, and volunteering are just a few of the activities that help admissions officials get a more comprehensive understanding of a student apart from their GPA and standardized test scores. Our Early Advising Program is a great way for 9th and 10th graders to get a head start on the college applications process. Paired with successful students at top-30 schools, high schoolers are advised on everything from choosing classes to what extracurricular activities to participate in—learning from students who just successfully navigated the application process and were admitted to a top school. Our College Strategy Program is designed for students further along in the college application process, helping high school juniors create college lists, solidify their college profile, and maximize this critical time in the admissions process. Most importantly, this program assists students in gaining admission into their first-choice schools—73% of participants enrolled in our College Strategy Program are accepted to top-20 schools. Estimating your chance of getting into a college is not easy in today’s competitive environment. Thankfully, with our state-of-the-art software and data, we can analyze your academic and extracurricular profile and estimate your chances. Our profile analysis tool can also help you identify the improvement you need to make to enter your dream school. If you’re preparing to build your college list and are thinking about pursuing a modern language major, you’re in luck—we’ve taken the first step for you.

Environmental Science Lab IP 5 Essay Example | Topics and Well Written Essays - 250 words

Environmental Science Lab IP 5 - Essay Example This is deposited at the bottom of the lake bed and then undergoes decomposition, yielding nutrients such as phosphorus and nitrogen that then accelerate the growth of algae species (Vanderploeg, et al., 2001). Using MUSE, the numbers of phytoplankton, zooplankton, Cladophara, Foraging fish and Lake Trout were recorded at intervals of 0, 4, 7, 10, 13, 16 and 20 years after the introduction of the Zebra and Quagga mussels to the ecosystem. The recorded results showed that the population of the Zebra and Quagga mussels, as well as the Cladophora biomass increased rapidly from 0-13 years. It then decreased in the subsequent years (16-20). Conversely, the populations of phytoplankton, zooplankton, Foraging fish and the Lake Trout decreased from 0-13 years, and then increased afterwards. The results showed that between 0-13 years of introduction, the population of the Zebra and Quagga mussels increased and that of the phytoplankton reduced since the mussels feed on the phytoplankton. The reduction of the phytoplankton population led to a reduction in the populations of the species that come next on the food chain (zooplankton, Foraging fish and Lake Trout). The biomass of Cladophora algae rose like that of the mussels rose because of the increase in nutrients such as nitrogen and phosphorus due to decomposition of pseudofecal matter. The population of the mussels rose up to the point where the available phytoplankton could not sustain their survival, resulting in a large number dying off. This led to a subsequent drop in the biomass of Cladophora algae because of the reduction in the amount of nutrients available. As the population of the mussels dropped, there was a slight increase in the population of the phytoplankton. This lead to a subsequent rise in the population of the species dependent on it both directly and indirectly. Benson, A. J., Raikow, D., Larson, J., & Fusaro, A. (2012, 06 06).
