All About the Periodic Table

All About the Periodic Table The periodic table of the elements is one of the most important tools used by chemists and other scientists because it summarizes useful information about the chemical elements in a format that shows relationships between the elements. Get Your Own Periodic Table You can find the periodic table in any chemistry textbook, plus there are apps for referring to the table from your phone. However, sometimes its nice to be able to have one open on your computer, to  save one to your desktop, or to print one off. Printed periodic tables are great because you can mark them up and not worry about ruining your book. Use Your Periodic Table A tool is only as good as your ability to use it! Once you are familiar with the way the elements are organized, you can locate them more quickly, get information from the periodic table, and draw conclusions about the properties of elements based on their location on the table. Periodic Table History Many people consider Dmitri Mendeleev to be the Father of the Modern Periodic Table. Mendeleevs table was slightly different from the table we use today in that his table was ordered by increasing atomic weight and our modern table is ordered by increasing atomic number. However, Mendeleevs table was a true periodic table because it organizes the elements according to recurring trends or properties. Get to Know the Elements Of course, the periodic table  is all about the elements. The elements are identified by the number of protons in an atom of that element. Right now, youll see 118 elements on the periodic table, but as more elements are discovered, another row will be added to the table. Quiz Yourself Because its necessary to know what the periodic table is and how to use it, you can expect to be tested about it from grade school pretty much until the end of time. Before your grade is on the line, probe your strengths and weaknesses with online quizzes. You might even have fun!

Integrated and Interdependent Global Economy Essay

Integrated and Interdependent Global Economy - Essay Example It not only saves time, energy and money, but also induces overall growth to the economy. It is not one country that will be benefitted, but all the countries who are involved in the bilateral trade will be immensely benefitted from the same.   Globalization has made a major impact on the world economies. The shift has been mainly towards a more integrated and interdependent economy. Here the market and the production unit must be merged together to give an integrated effect. Also, the geographical factor has been considered when this interdependency aspect has been implemented. This is a good concept because the economy has been merged to source the local services and products and make it available to the huge global market and also to take advantage of the individual national distinctiveness and the other factors of production like energy, land, capital, and labor.   In this perspective, the matter of outsourcing refers to the concept of sharing of the production and service operations in an overseas country and also it helps in hiring the employees in a different location rather than employing the people in-house. The processes and functions, which   are being outsourced most often, are supply chain by 36%, learning - training by 31%, information technology by 43%, finance and accounting by 21%, human resources by 25% and customer relationship management by 13%.   The free trade generates gains for all the countries which take part in the system of free trade, but as the factor of globalization moves throughout the U.S. financial system, many people dispute the effect of outsourcing on the jobs they hold.

Explain the growth in the concentration of media ownership around the Assignment

Explain the growth in the concentration of media ownership around the world - Assignment Example Founded and headquartered in Australia, the company now boasts of being the number one newspaper publisher in the world, with a cumulative daily readership of 14 million in these three countries alone. Murdoch has a near monopoly in the media space in Australia, owning two-thirds of all newspaper circulation in the country. Across the Tasman Sea, in New Zealand, he owns nearly half. Further, he is the owner of two fifths of the Australian Associated Press. (Knowlton & Parsons, 2005, p. 200) These holdings are notwithstanding his considerable market share in Britain and the United States. These statistics bear testimony to the Murdoch’s media monopoly. Between the lines one can read the dangers posed by monopoly in an industry that is crucial to socio-cultural discourse. One of the negative consequences of media concentration is that it nullifies ethical standards of journalism. News Corp’s official Standards of Business Conduct (SBC) document makes some bold claims. But the company’s actual behaviour is contradictory to these claims. For example, in the area of building trust with business partners and customers, it claims that trust and integrity are of utmost importance. The manner in which the company actually functions makes a mockery of these ethical concerns. There are several instances where News Corp had colluded with political organizations to attain favourable deals. One of the first instances of News Corp’s opportunistic use of political connections came to light in1995. Murdoch struck a book deal with the then House Speaker of the United States Congress Newt Gingrich for a substantial sum of $4.5 million. The ethical problem was obvious in this case. Murdoch, who was even at that time an influential and trans-global media personality, owned a newspaper chain and several television stations. He stood to gain enormously through the relationship with the Speaker. It was only after severe public

Medicare and Medicaid Cuts Essay Example for Free

Medicare and Medicaid Cuts Essay The debate on health care spending has been highly contested and remains the top most agenda on the Obama administration. The U. S government has been pursuing effective health care reforms for quite a long period of time. Focus has been on developing a plan that reduces government spending on heath and home care reimbursements while increasing the regard for insurance cover. An important aspect of these reforms is the reduction in budgetary spending on Medicare and Medicaid programs (Meena, et al. 006). President Obama in 2009 announced the $ 313 reduction in Medicaid and Medicare efficiencies as a move to accomplish the proposed savings essential for facilitating the administration’s heath-care plan. Currently, the cut on Medicare reimbursements paid for health care access costs by psychiatric patients, the elderly and the disabled stands at about 21%. In justifying these cuts, the U. S government points out that the funds would be less essential in the light of a new health care reform. However, at the current economic status and the increasingly declining rates of hospital revenues, this move has resulted into the rationing of medical and home care services, high payroll taxes, and closure of departments and hospitals. According to a study conducted by the American Hospital Association (AHA) regarding these cuts, about one in every five hospitals have already reduced a number of health care services such as outpatient services, post-acute care and behavioural health; as they have had to reduce overhead costs resulting from the cuts (Shen, 2003). These cuts will affect millions of people especially seniors, military families and the disabled who depend greatly on Medicare. This is because accessibility to physician help will be minimized. In support of medical practitioners, The American Medical Association (AMA) argues against these cuts on the basis that they are derived through an unreliable method of determining the physicians’ reimbursements and which according to them ought to be reviewed. It is imperative to also note that the effects of these cuts are being transferred to the public through increased insurance costs. Effects on Access, Cost and Quality of Psychiatric Care There is evidence that patient’s access to health and home care has been increasingly diminishing in the past few years and even got worse following the recent 21% Medicare cuts. Physicians argue that this has been prompted by the increased costs in the provision of medical care services due to the reimbursement cuts. For instance, by the year 2005, medical care provision costs had been projected to be about 40% more than the in 1991 (White, Dranove 1998). In 2008, about $ 879 million was spent by hospitals in Michigan in subsiding services for the patients affected by the cuts. There have also been care rationing, reduction in provision of vital medical services and closure of hospital departments has been prevalent. This means that access to heath care services by concerned individuals has reduced significantly. A number of medical practitioners have been forced to stop providing psychiatric services to patients due to high overhead costs (Meena, et al. 2006). The reduced Medicare and Medicaid reimbursements have made it impossible for psychiatrists to effectively provide care to long-term-care clients as well. There are reports of psychiatrists declining to provide consultation services in nursing homes as result of the lower rates of Medicaid and Medicare reimbursements received. According to the chair of the Geriatric Psychiatry committee for the Maryland Psychiatric Society, Allan Anderson, the cuts are a drawback to the willingness of the psychiatrists to provide care for the Medicare-based patients (Mulligan, 2002). Geriatric patients currently are underserved. Psychiatrists argue that due to a reduced access to psychiatric care such in cases demanding early interventions, most psychiatric patients are ending up complications. Doctors note that the cuts make it difficult for them to meet the requirements of their practice such as administrative issues and thus end up restricting their caseloads on Medicare. Currently, Medicaid does not take responsibility of the complete co pay for patients on both the Medicaid and Medicare and this has made a number of clinics to close to avoid the extra burden of absorbing the costs of treating these patients. For instance, Minnesota’s Mayo Clinic incurred a loss of about $ 34. 2 million in years 2002 and 2003 due to these cuts and it is such losses that are pushing clinics to close down minimizing access to health acre even more. Access to healthcare for the Medicare patients is increasingly becoming expensive and complicated given that the ability to pay currently determines this access (White, Dranove 1998). Most heath facilities have had to cut down on their provisions of vital services that the seniors, the metal disabled and the military personnel within the community rely on to protect their bottom lines. Affected patients are being forced to skip visits to hospitals and this has prompted the providers to restrict access through costs. Impact on Psychiatrists and Other Medical and Home Care Providers A study of about 14,000 anaesthologists and surgeons indicate that most medical care providers will change their practice thus jeopardizing health care provision. A third of those studied said they will cease to practice as Medicare psychiatrists. This will adversely affect their quality of life. Practical challenges are forcing the providers to halt providing some Medicare related services, cutback on staff, minimize time allocated for Medicare patients and/or halt further purchase of equipments essential for serving such patients (Konetzka, et al. 2005). This will limit the doctor’s practice adversely. Some medical and home care providers have been forced to quit their practice following the high overhead resulting from the high costs incurred in attending to Medicare patients. Hospitals are being forced to resize on Medicare patients’ staff since hospitals have had to absorb care costs. Individual practitioners are more affected. Reimbursements cuts are prompting hospitals to focus on other non-reimbursement-dependent care services while closing down departments as well as cutting back on services to enable hospitals protect their bottom lines. This trend is prevalent even in community hospitals. In this regards, hospitals and home care provision establishments have had to reduce the number of practitioners providing these services and hence most are on the verge of losing their jobs should the cuts continue as anticipated (Mulligan, 2002). This implies that the government will only be solving on problem while creating multitude of others such unemployment. Many hospitals have also resulted in freezing of workers’ salaries and hence compromising their motivation. Impact on Taxpayers According to Randall (2009), the 2005’s 3 % reimbursement cut resulted into a $ 49 billion in terms of cost on permanent reforms. Currently, the Medicare reimbursement cut stands at 21% at a reform cost of about $ 210 billion. Medicare and Medicaid programs are funded by pay roll taxes. According to the health care reform bill, there will be an expansion of the pay roll tax associated with the Medicare to cover unearned income. It is projected that beginning year 2018; insurance firms will be required to pay an excise tax of about 40% for plans where family premiums range from $ 27, 500 and above (Sam, 2006). Experts note that these payroll tax effects will be transferred to employees in terms of lowers wages and benefits or in terms of higher premiums. This comes at a time when the government is focused on laying strict measure to ensure that people have health insurance. Further, it is also projected that from year 2013, adjustable spending accounts which currently enable users to skip various expenses on health care, will reduced or limited. In regards to the high income earning population, families earning in excess of $ 250, 000 will be required to spend way above what they spend currently on medical payroll taxes. Moreover, the now exempt unearned income will also be subjected to 3. 8 percent in payroll taxes. Individuals and families are definitely feeling the weight of these Medicaid and Medicare cuts through increased payroll taxes. This is because the federal government is focusing on insurances an alterative to help patients meet their health care costs. A 2005study by the Kaiser Family Foundation on employer health benefits indicates that family coverage premiums had increased by an average of about 9. 2 percent (Sam, 2006). Health insurance expenses have made it costly to employees as they are subjected to deductions for the same. At the same time, the mean per month contribution by employees on family plans increased to $ 226 in year 2005 form 2000’s $135. These are some of the costs that the citizens are bearing at the expense of the reduction in Medicare and Medicaid cuts.

Fort Pillow Attack :: essays papers

Fort Pillow Attack THE GRAND FABRICATION It is almost as difficult to find consistent information about the incident at Fort Pillow as it is to determine the moral significance of its outcome. Scholars disagree about exactly what transpired on April 12, 1864 at Fort Pillow, when General Nathan Bedford Forrest captured the fort with his 1,500 troops and claimed numerous Union lives in the process (Wyeth 250). It became an issue of propaganda for the Union, and as a result the facts were grossly distorted. After close examination it is clear that the  ³Fort Pillow Massacre ² (as it became known by abolitionists) was nothing of the sort. The 1,500 troops under the command of General Nathan Bedford Forrest acted as men and as soldiers in their capture of Fort Pillow. It is first necessary to understand what happened in the battle before any judgment can be made. A careful study performed by Dr. John Wyeth revealed the following information: from April 9-11, 1864, troops under the command of Ben McCulloch, Tyree Harris Bell, and Brig. General James Chalmers marched non-stop to Fort Pillow to begin their assault under the command of General Nathan Bedford Forrest. Confederate sharpshooters claimed the lives of several key Union officers during the morning assault on the fort. The losses included the commanding officer Major Loinel F. Booth, and his second in command shortly after that. These losses created a complete breakdown of order and leadership among the Union troops within the fort. (251) During the morning engagement, the gun boat the New Era was continually attempting to shell the Confederate forces from the Mississippi, but with minimal success. The Union forces fought back heartily until around one o ¹clock in the afternoon, when both sides slowed down. Around that time the New Era steamed out of range to cool its weapons. It had fired a total of 282 rounds, and its supplies were almost totally exhausted. During this hiatus in the firing, while Confederate troops waited for supplies that would arrive around three o ¹clock, Forrestwas injured when his horse fell on him after being mortaily wounded (252). When the supplies arrived, Confederate troops under a flag of truce delivered a message from Forrest that said,  ³My men have received a fresh supply of ammunition, and from their present position can easily assault and capture the fort, ² (253). Forrest demanded  ³the unconditional surrender of the garrison, ² promising

Lord of the flies writing assignment

They were reported issuing a month ago on Tuesday July 21st, after a plane supposedly â€Å"dropped† them off at a Remote Island. No one hasn't really heard of them since, but Police from all over Canada, the United States, Mexico, and the UK has been looking for these boys. Officials say that some sailors have found them on an island, which was smoking. Around 2-3 boys have been reported dead; the names have not been released as yet. â€Å"We found shelter, and got some food† 8 year old Sam, a younger boy rescued from the island. â€Å"Some of the boys were rude to other boys but they solved some of their problems† 8 ear old Eric said.Now the big question is what happened on the island? â€Å"On that island, have been some really traumatizing events. Some have lost their lives on that island, but most survived. There have been some really awful conflicts but thankfully reality saved us. † 12 year old Ralph said. ‘We were civilized at one point in ti me but we got out of hand, but I'm glad that's all over and that we can move on in our lives. † 12 year old Jack told us. All the boys are safe home now and officers are going back to the island to investigate and find the lost boys.

Critical Review of Greasy Lake

When I began reading â€Å"Greasy Lake† by T. Coraghessan Boyle, I thought these boys were exhibiting typical behavior of young-adult men and their behavior led them to trouble. Boyle kept my interest by anticipation and disgust at the boys of the boy’s behavior in this story. The narrator, who is the main character of the story, often describes himself and his friends as â€Å"bad characters† and this becomes more convincing in the story. Boyle also used Greasy Lake at not only the setting for this story but also as a character. He described the lake as â€Å"fetid and murky, the mud banks glittering with broken glass and strewn with beer cans and the charred remains of bonfires. † Greasy Lake is used as a symbol for the youth culture itself in the story and is littered by alcohol, sex and violence. When the boys first came across the greasy man at the lake, their attitudes change for a moment, all three of them are scared. When they began to fight with the man, the narrator grabbed the tire iron out of fear. Once the three of them beat him up and knock him unconscious, I think this only increased their already arrogant attitudes. When they attempt to rape the greasy man’s lady companion, I think that shows how truly pathetic each of them are, acting like â€Å"deranged brothers†. In a very disturbing way, the boys were asserting a primal physical dominance over the woman. I think Boyle’s was sending a message that there are consequences for our actions. Even though kids tend to think they’re big and bad and have it all figured out, these once cocky boys quickly became horrified once they had to face the consequences of their actions. I personally enjoyed reading â€Å"Greasy Lake† very much. The language in the story Boyle used is crude and literal, but it goes with the theme of â€Å"badness† portrayed by his characters. Boyle emphasizes the corruption of the lake by using it as a not only the setting, but also as tool to compare the narrator and the youth of the time. In the beginning, the narrator is as corrupted as the lake; though born pure and â€Å"clear† he becomes tainted by the â€Å"beer† and wildness of his culture. By ending with the beaten narrator and his friend refusing drugs and driving home, Boyle left me with a sense of for the boys that they are not really â€Å"bad characters† after all. The narrator has realized the consequences of his actions, and that he can no longer act invincible.

Lesson Plan on Present Perfect and Past Simple

Lesson Plan on Present Perfect and Past Simple The switch between the present perfect and the past simple is one of the most challenging aspects for English learners. There are a few reasons for this: Students use a language - such as German, French or Italian - which uses its version of the past simple and the present perfect interchangeably.Students find the difference between specific past experience (past simple) and general experience (present perfect) difficult.Students speak a language in which tense usage is much more loose such as Japanese. This lesson focuses on the switch by first narrowing the choices down to either the present perfect or the past simple. It asks students to first ask questions about general experience with ever and then drill down to the specifics with question words such as where, when, why etc. Aim Becoming more proficient in switching between the present perfect and the past simple Activity Number 1 Asking about experiences # 2 Writing about experiences Level Lower-intermediate to intermediate Outline Begin the lessons by speaking about your own experiences in a general way. Be careful not to give any details about these experiences. In other words, keep to the present perfect. I find topics such as travel, education, and hobbies work well. For example: Ive been to many countries in my life. Ive traveled in Europe and Ive visited France, Germany, Italy, and Switzerland. Ive also driven a lot in the United States. In fact, Ive driven through almost 45 states. Ask students to ask you questions about the specifics of some of your adventures. You may need to model this. However, students will hopefully be able to catch on fast and keep to the past simple. On the board, create a timeline showing past to present with some of your adventures. Put question marks above the general statements, specific dates above specific statements. Point out the difference between the two. You can use the ​tense time charts on this site as well. Introduce the question Have you ever ... for general experience. Review information questions in the past simple to focus on specific experiences. Model a few question-and-answer exchanges with students switching between Have you ever... followed by information questions When did you ..., Where did you ..., etc. when students answer in the affirmative.   Have students complete exercise one with partners or in small groups.   Moving around the class, listen to these conversations helping when necessary. To continue, ask students to fill in the worksheet following the example provided. Move around the room making sure students are switching between the present perfect and the simple past in writing. Exercise 1 Use the present perfect with Have you ever... to ask your classmates questions. When your partner answers yes, follow-up with information questions in the past simple. For example: Student 1: Have you ever been to China?Student 2: Yes, I have.Student 1: When did you go there?Student 2: I went there in 2005.Student 1: Which cities did you visit?Student 2: I visited Beijing and Shanghai. buy a new cartravel in a foreign countryplay football / soccer / tennis / golfwork in a large companyfly over the oceaneat something that made you sickstudy a foreign languagelose your money, wallet, or purseeat snailsplay an instrument Exercise 2 Write a few sentences on each of these topics. First, begin with a sentence using the present perfect. Next, write a sentence or two giving specific details. For example: I have learned three languages in my life. I studied German and Italian when I was in college. I also learned French when I visited the country for a three-month French language program in 1998.   Hobbies I have learnedPlaces I have visitedCrazy food I have eatenPeople I have metStupid things I have boughtSubjects I have studied
