    The Advantages and Disadvantages of Social Networking 

    Social networking is a recent invention that has the Internet still at the edge of its seat due to its popularity with people. This is mostly because it really is for the people. Bringing every kind of social group together in one place and letting them interact is really a big thing indeed. Everything about it lies on the advantages and disadvantages of social networking, and what it can do for you.

    Here are the advantages that can be more than enough for you to want to join in.Definitely, it’s cheaper to use online social networking for both personal and business use because most of it is usually free. While personal use is rather simple for anyone, the business functions are underestimated by many. In a social networking site, you can scout out potential customers and target markets with just a few clicks and keystrokes, adding a boost to your usual advertisements and promotional strategies. It lets you learn about their likes and dislikes, which is tremendous. If you want to fine tune your business, then this is the way to go, whether on a budget or not.

    Builds Credibility

    You definitely can gain the customers’ confidence if you can connect to them on both a personal and professional level. Despite having to do a bit of work, it definitely pays off as you can be tapped for an offer if someone catches wind of your products or services. As long as you don’t pursue them too aggressively, you will do well here.

    Connections

    You are friends with people who have other friends, and so on. There is potential in such a common situation. By using a social networking site, you can do what you can and get connected with these people to form a web of connections that can give you leverage if you play your cards right. As long as you give as well as you recieve, then they will most likely stick with you. These connections are definitely valuable in the long run.

    That definitely sounds enticing. However, what about the disadvantages though?

    Lack of Anonymity

    You are putting out information about your name, location, age, gender, and many other types of information that you may not want to let others know. Most people would say be careful, but no one can be certain at any given time. As long as people can know who you exactly are, then some can find ways to do you in.

    Scams and Harassment

    There is a potential for failure of security in both personal and business context. While many sites apply certain measures to keep any of these cases of harassment, cyber-stalking, online scams, and identity theft to an absolute minimum, you still may never know.

    Time Consuming

    If this is not your kind of thing, that it would just be a waste of time for you. The key to social networking is that it is supposed to be fun, whether you are just doing it for kicks or clicking around for business purposes. That should be reasonable enough for anyone, but there are those people who don’t see the point. For them, it can be a disadvantage.

    Now there is something to really think about. Nothing is without a blemish, but those of this type of networking shouldn’t really be that much of a concern regarding your safety. As long as you go along without making big mistakes, then it is all good. You can take advantage of the Internet phenomenon that continues up to this day.

    Dangers of Smoking 

    Dangers Of Smoking With Nicotine

    One of the main dangers of smoking is due to Nicotine. Nicotine is found naturally in tobacco. It has no odor and no color. It is, however, both physically and psychologically addictive, and it causes those who use it to want to smoke one cigarette after another.

    Nicotine enters the body as tiny droplets resting on particles of tar in cigarette smoke. Inhaled into the lungs, the drug passes quickly into the bloodstream, reaching the brain within about 10 seconds. In another 5 to 10 seconds the nicotine has spread to all parts of the body.

    The nicotine raises both the heart rate and blood pressure. The smoker quickly feels more alert and relaxed. In less than 30 minutes, however, about half of the nicotine has left the bloodstream, and the smoker starts feeling less alert, more edgy.

    So he or she reaches for another cigarette to get a new “hit” of nicotine. Over time, the smoker starts needing more cigarettes throughout the day to satisfy the craving.

    Dangers Of Smoking With Tar

    There are other dangers of smoking as well. The tar from tobacco smoke starts to accumulate on the bronchial tubes leading to the lungs. The hot smoke burns the tiny hairlike projections (called cilia) that trap harmful particles before they enter the lungs.

    Carbon Monoxide

    One more of the dangers of smoking are Carbon monoxide. Smoking also increases the level of carbon monoxide in the lungs. This poisonous gas is quickly absorbed into the blood, reducing its capacity to carry oxygen.

    As a result, the smoker has to exert more physical effort to attain a given task than does a nonsmoker. The heart in particular must work harder, particularly during rigorous exercise. Increased levels of carbon monoxide in the blood can impair vision, perception of time, and coordination.

    Diseases

    Smoking is the one of the main cause of death every year. Smoking cause number of smoke related diseases such as lung cancer (Smoking and Lung Cancer), respiratory problems and heart ailments and these dangers of smoking are increasing yearly.

    Certain breathing disabilities are also the dangers of smoking. It could also result in a decreased capability to enjoy physical capabilities because of the ailment or side effects like breathing problems. Smoking leads to reduction in life expectancy.

    Over the years a smoker will be more likely to develop respiratory ailments, thickening of the arteries, blood clots, cancer of the lung, cervix, larynx, mouth, esophagus, bladder, pancreas, and kidney, and emphysema, as well as exhibit symptoms such as reduced stamina, poor athletic performance, wheezing, coughing, dizziness, and nausea.

    In time, a smoker suffers increased resistance to the flow of air into the lungs and reduced lung capacity. Besides these serious problems, prolonged tobacco use leads to stained teeth and fingers and bad breath. Even a smoker’s clothes and living quarters tend to smell of tobacco.

    Smoking Is A Costly Affair

    Smoking is a costly affair. An ordinary smoker invites enormous cost to maintain this unhealthy lifestyle and the costs do not affect exclusively to him. The most apparent cost of smoking is the daily, weekly and monthly expenditure of an ordinary smoker.

    The average cost of pack of Cigarettes is $4.00. Imagine a smoker burning a pack per day, $4.00 per day. Annually the money spent on smoking would be around $1500. This money could have spent on some thing good like a decent out-of-town vacation.

    Medical Expenditure

    Medical expenditures will also have to be addressed as most, if not all, smoke related diseases require treatment, services and medication. Health care services do not always come free.

    At the same time, due to illness the smoker has to refrain from work and forced to retire to the hospital be. This leads to reduce in income level and there after, instead of bringing in more money to the household, the money had to be taken out.

    Secondhand Smoking

    Another one of the dangers of the smoking is that smoking not only diminishes the health of the smokers but also diminishes the health of the non smokers around him through secondhand smoking

    Facial Charm

    Bad breath brought about by smoking would require gum or mints to overcome the odor. The smoker may also opt for breath fresheners, which are even more expensive. Cigarette components stain the teeth.

    Having yellow teeth means extra charge from the dentist aside from the usual cleaning. Smokers were also found to have darkened gums. Smoking could also effect the wrinkling of the skin earlier than the usual.

    Other Dangers Of Smoking

    Smoking gives a higher risk of starting a fire. Many fires had been discovered to originate from a cigarette left lit. It also leads to air pollution due to the constant release of carbon monoxide in the proximate vicinity.

    Presently, the insurance companies are charging more premium for smokers. Smokers who die early do not get to enjoy the fruits of their pensions. This means less social security benefits.

    Cigarette smoking also affects the overall aesthetics of the person. Smoking also leads to breakups with their loved ones. Smoke makes clothes dirty and the resulting in increase in money spent on dry cleaning. The smoke can also result in bad smell in the skin and hair (Bad Breath and Smoking).

    Smoking also has emotional costs. The dependence to smoking when one gets addicted can be very restricting. There is also the pressure to quit smoking as the smoker realizes the harmful effects to himself and to his or her family.

    What is Antivirus? 

    Antivirus software is a computer program that detects, prevents, and takes action to disarm or remove malicious software programs, such as viruses and worms. You can help protect your computer against viruses by using antivirus software, such as Microsoft Security Essentials.

    Computer viruses are software programs that are deliberately designed to interfere with computer operation, record, corrupt, or delete data, or spread themselves to other computers and throughout the Internet.

    To help prevent the most current viruses, you must update your antivirus software regularly. You can set up most types of antivirus software to update automatically.

    For on-demand protection, Windows Live safety scanner allows you to visit a Web site and scan your computer for viruses and other malicious software for free.

    Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.

    A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.

    Computer viruses are often spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it’s from and you are expecting it.

    Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.

    Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.

    To help avoid computer viruses, it’s essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats, run your computer as a standard user (not as administrator), and that you follow a few basic rules when you surf the Internet, download files, and open attachments.

    Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.

    Disadvantages of computer game? 

    Where on one hand the games do prove to be beneficial to an extent, at the same time, its ill effects cannot be ignored. Doctors have found a possible threat to these frequent gamers, affecting their health. Common complaints found among children obsessed with games are eye strains, wrist, neck and back pains, etc. Photosensitive epilepsy, headaches, hallucinations, nerve and muscle damages etc. Speculation is going on about whether playing games can cause obesity in the long run.

    Specialists have confirmed that children who spend too much time playing computer games not only are easily susceptible to long terms problems like bad posture and RSI (repetitive strain injury), but it also causes a disequilibrium in their daily routine. This stands true not only for children playing games but also for those who spend long hours on the computer. Dr Diana Macgregor of the Royal Aberdeen Children’s Hospital has highlighted the case of an 11-year-old boy who suffered from tendonitis following long periods on his Nintendo Game Boy, a condition that has come to be known as ‘Nintendonitis’. RSI is not as simple as it sounds. Its treatment is generally a long difficult process. It could be anything from simple relaxation exercises to Physiotherapy and hydrotherapy. Is this really something that parents would like their children to go through?

    Spending many hours in front of the monitor and not going out enough could also cause social problems thus resulting in them becoming shy and introvert. Apart from that the games developed nowadays happen to be a lot more violent thus the gamers do have a tendency to lose control and become more aggressive.

    A controversial new research has proved that excessive playing of games can actually stunt the growth of a human brain. Brain-mapping expert Professor Ryuta Kawashima and his team at Tohoku University in Japan measured the level of brain activity in teenagers playing a Nintendo game and compared it with those who played other arithmetic games. It was concluded that the Nintendo game stimulated activity only in the parts of the brain associated with vision and movement. While arithmetic games stimulated brain activity in both the left and right hemispheres of the frontal lobe. The frontal lobe of the brain is associated with learning, memory and emotion and continues to develop till the age of 20. Hence it is a matter of concern. Though the games do provide certain benefits, the question is how much and is it really worthwhile.

    Parents need to keep track of how much time their children spend in front of the screen playing games and also as to what type of games they play. Every aspect has its advantages and disadvantages; so is the law of nature.

    US 44th president;Mr Barack Hussein Obama 

    Barack Hussein Obama II ; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. Obama previously served as the junior United States Senator from Illinois from January 2005 until he resigned after his election to the presidency in November 2008.

    Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004.

    Obama served three terms in the Illinois Senate from 1997 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, he ran for United States Senate in 2004. During the campaign, several events brought him to national attention, such as his victory in the March 2004 Democratic primary election for the United States Senator from Illinois as well as his prime-time televised keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in November 2004.

    Obama’s presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Clinton, he won his party’s nomination. In the 2008 general election, he defeated Republican nominee John McCain and was inaugurated as president on January 20, 2009. Obama is also the 2009 Nobel Peace Prize laureate.

    Early life and career

    Barack Obama was born at Kapi’olani Maternity & Gynecological Hospital in Honolulu, Hawaii, United States, to Stanley Ann Dunham, an American of predominantly English descent from Wichita, Kansas,and Barack Obama, Sr., a Luo from Nyang’oma Kogelo, Nyanza Province, Kenya Colony. Upon his election, he became the first President born in Hawaii. Obama’s parents met in 1960 in a Russian language class at the University of Hawaii at Mānoa, where his father was a foreign student on scholarship. The couple married on February 2, 1961, and Barack was born later that year. His parents separated when he was two years old and they divorced in 1964. Obama’s father remarried and returned to Kenya, where he had two more sons, David and Mark Ndesandjo. The senior Obama saw his first son only once more before dying in an automobile accident in 1982.

    After her divorce, Dunham married Indonesian student Lolo Soetoro, who was attending college in Hawaii. When Suharto, a military leader in Soetoro’s home country, came to power in 1967, all Indonesian students studying abroad were recalled and the family moved to the island nation. They lived in the Menteng area of Jakarta. From ages six to ten, Obama attended local schools in Jakarta, including Besuki Public School and St. Francis of Assisi School.

    In 1971, Obama returned to Honolulu to live with his maternal grandparents, Madelyn and Stanley Armour Dunham, and attended Punahou School, a private college preparatory school, from the fifth grade until his graduation from high school in 1979.

    Obama’s mother returned to Hawaii in 1972, remaining there until 1977 when she relocated to Indonesia to work as an anthropological field worker. She finally returned to Hawaii in 1994 and lived there for one year before dying of ovarian cancer.

    Of his early childhood, Obama recalled, “That my father looked nothing like the people around me—that he was black as pitch, my mother white as milk—barely registered in my mind.” He described his struggles as a young adult to reconcile social perceptions of his multiracial heritage.Reflecting later on his formative years in Honolulu, Obama wrote: “The opportunity that Hawaii offered—to experience a variety of cultures in a climate of mutual respect—became an integral part of my world view, and a basis for the values that I hold most dear.” Obama has also written and talked about using alcohol, marijuana and cocaine during his teenage years to “push questions of who I was out of my mind. At the 2008 Civil Forum on the Presidency, Obama identified his high-school drug use as his “greatest moral failure.”

    Following high school, Obama moved to Los Angeles in 1979 to attend Occidental College. After two years he transferred in 1981 to Columbia University in New York City, where he majored in political science with a specialization in international relation, and graduated with a B.A. in 1983. He worked for a year at the Business International Corporation, then at the New York Public Interest Research Group.

    Chicago community activism and Harvard Law

    After four years in New York City, Obama moved to Chicago, where he was hired as director of the Developing Communities Project (DCP), a church-based community organization originally comprising eight Catholic parishes in Greater Roseland (Roseland, West Pullman and Riverdale) on Chicago’s far South Side. He worked there as a community organizer from June 1985 to May 1988. During his three years as the DCP’s director, its staff grew from one to thirteen and its annual budget grew from $70,000 to $400,000. He helped set up a job training program, a college preparatory tutoring program, and a tenants’ rights organization in Altgeld Gardens. Obama also worked as a consultant and instructor for the Gamaliel Foundation, a community organizing institute. In mid-1988, he traveled for the first time in Europe for three weeks and then for five weeks in Kenya, where he met many of his paternal relatives for the first time. He returned in August 2006 in a visit to his father’s birthplace, a village near Kisumu in rural western Kenya.

    In late 1988, Obama entered Harvard Law School. He was selected as an editor of the Harvard Law Review at the end of his first year, and president of the journal in his second year. During his summers, he returned to Chicago, where he worked as a summer associate at the law firms of Sidley Austin in 1989 and Hopkins & Sutter in 1990. After graduating with a Juris Doctor (J.D.) magna cum laude from Harvard in 1991, he returned to Chicago. Obama’s election as the first black president of the Harvard Law Review gained national media attention and led to a publishing contract and advance for a book about race relations, though it evolved into a personal memoir. The manuscript was published in mid-1995 as Dreams from My Father.

    Return to Chicago

    From April to October 1992, Obama directed Illinois’s Project Vote, a voter registration drive with a staff of ten and 700 volunteers; it achieved its goal of registering 150,000 of 400,000 unregistered African Americans in the state, and led to Crain’s Chicago Business naming Obama to its 1993 list of “40 under Forty” powers to be.

    For 12 years, Obama was a constitutional law professor at the University of Chicago Law School; as a lecturer from 1992 to 1996, and as a senior lecturer from 1996 to 2004. In 1993 he joined Davis, Miner, Barnhill & Galland, a law firm of 12 attorneys that specialized in civil rights litigation and neighborhood economic development, where he was an associate for three years from 1993 to 1996, then of counsel from 1996 to 2004, with his law license becoming inactive in 2002.

    Obama was a founding member of the board of directors of Public Allies in 1992, resigning before his wife, Michelle, became the founding executive director of Public Allies Chicago in early 1993. He served from 1994 to 2002 on the board of directors of the Woods Fund of Chicago, which in 1985 had been the first foundation to fund the Developing Communities Project, and also from 1994 to 2002 on the board of directors of the Joyce Foundation. Obama served on the board of directors of the Chicago Annenberg Challenge from 1995 to 2002, as founding president and chairman of the board of directors from 1995 to 1999. He also served on the board of directors of the Chicago Lawyers’ Committee for Civil Rights Under Law, the Center for Neighborhood Technology, and the Lugenia Burns Hope Center.

    Political career: 1996–2008

    State legislator: 1997–2004

    Obama was elected to the Illinois Senate in 1996, succeeding State Senator Alice Palmer as Senator from Illinois’s 13th District, which at that time spanned Chicago South Side neighborhoods from Hyde Park-Kenwood south to South Shore and west to Chicago Lawn. Once elected, Obama gained bipartisan support for legislation reforming ethics and health care laws. He sponsored a law increasing tax credits for low-income workers, negotiated welfare reform, and promoted increased subsidies for childcare. In 2001, as co-chairman of the bipartisan Joint Committee on Administrative Rules, Obama supported Republican Governor Ryan’s payday loan regulations and predatory mortgage lending regulations aimed at averting home foreclosures.

    Obama was reelected to the Illinois Senate in 1998, defeating Republican Yesse Yehudah in the general election, and was reelected again in 2002. In 2000, he lost a Democratic primary run for the U.S. House of Representatives to four-term incumbent Bobby Rush by a margin of two to one.

    In January 2003, Obama became chairman of the Illinois Senate’s Health and Human Services Committee when Democrats, after a decade in the minority, regained a majority. He sponsored and led unanimous, bipartisan passage of legislation to monitor racial profiling by requiring police to record the race of drivers they detained, and legislation making Illinois the first state to mandate videotaping of homicide interrogations. During his 2004 general election campaign for U.S. Senate, police representatives credited Obama for his active engagement with police organizations in enacting death penalty reforms. Obama resigned from the Illinois Senate in November 2004 following his election to the U.S. Senate.

    2004 U.S. Senate campaign

    In May 2002, Obama commissioned a poll to assess his prospects in a 2004 U.S. Senate race; he created a campaign committee, began raising funds and lined up political media consultant David Axelrod by August 2002, and formally announced his candidacy in January 2003. Decisions by Republican incumbent Peter Fitzgerald and his Democratic predecessor Carol Moseley Braun not to contest the race launched wide-open Democratic and Republican primary contests involving fifteen candidates. In the March 2004 primary election, Obama won in an unexpected landslide—finishing with 53% of the vote in a seven candidate field, 29 percentage points ahead of the runner-up—which prompted the New York Times to refer to him as a rising star within the national Democratic Party and started speculation about a presidential future.

    In July 2004, Obama wrote and delivered the keynote address at the 2004 Democratic National Convention in Boston, Massachusetts. Though it was not televised by commercial broadcast television networks, a combined 9.1 million viewers saw Obama’s speech, which was a highlight of the convention and elevated his status within the Democratic Party.

    Obama’s expected opponent in the general election, Republican primary winner Jack Ryan, withdrew from the race in June 2004. Six weeks later, Alan Keyes accepted the Illinois Republican Party’s nomination to replace Ryan. In the November 2004 general election, Obama won with 70% of the vote.

    U.S. Senator: 2005–2008

    Obama was sworn in as a senator on January 4, 2005. Obama was the fifth African American Senator in U.S. history and the third to have been popularly elected. He was the only Senate member of the Congressional Black Caucus. CQ Weekly characterized him as a “loyal Democrat” based on analysis of all Senate votes in 2005–2007. The National Journal ranked him as the “most liberal” senator based on an assessment of selected votes during 2007; in 2005 he was ranked sixteenth most liberal, and in 2006 he was ranked tenth. In 2008, Congress.org ranked him as the eleventh most powerful Senator, and the politician who was the most popular in the Senate, enjoying 72% approval in Illinois. Obama announced on November 13, 2008 that he would resign his senate seat on November 16, 2008, before the start of the lame-duck session, to focus on his transition period for the presidency. This enabled him to avoid the conflict of dual roles as President-elect and Senator in the lame duck session of Congress, which no sitting member of Congress had faced since Warren Harding.

    Legislation

    Obama voted in favor of the Energy Policy Act of 2005 and cosponsored the Secure America and Orderly Immigration Act. In 2005, Obama voted for H.R. 3199, the USA PATRIOT Improvement and Reauthorization Act.In September 2006, Obama supported a related bill, the Secure Fence Act. Obama introduced two initiatives bearing his name: Lugar–Obama, which expanded the Nunn–Lugar cooperative threat reduction concept to conventional weapons, and the Coburn–Obama Transparency Act, which authorized the establishment of USAspending.gov, a web search engine on federal spending On June 3, 2008, Senator Obama, along with Senators Thomas R. Carper, Tom Coburn, and John McCain, introduced follow-up legislation: Strengthening Transparency and Accountability in Federal Spending Act of 2008.

    Obama sponsored legislation that would have required nuclear plant owners to notify state and local authorities of radioactive leaks, but the bill failed to pass in the full Senate after being heavily modified in committee. On the issue of tort reform, Obama voted for the Class Action Fairness Act of 2005 and the FISA Amendments Act of 2008, which grants immunity from civil liability to telecommunications companies complicit with NSA warrantless wiretapping operations.

    In December 2006, President Bush signed into law the Democratic Republic of the Congo Relief, Security, and Democracy Promotion Act, marking the first federal legislation to be enacted with Obama as its primary sponsor. In January 2007, Obama and Senator Feingold introduced a corporate jet provision to the Honest Leadership and Open Government Act, which was signed into law in September 2007. Obama also introduced Deceptive Practices and Voter Intimidation Prevention Act, a bill to criminalize deceptive practices in federal elections and the Iraq War De-Escalation Act of 2007, neither of which has been signed into law.

    Later in 2007, Obama sponsored an amendment to the Defense Authorization Act adding safeguards for personality disorder military discharges. This amendment passed the full Senate in the spring of 2008. He sponsored the Iran Sanctions Enabling Act supporting divestment of state pension funds from Iran’s oil and gas industry, which has not passed committee, and co-sponsored legislation to reduce risks of nuclear terrorism. Obama also sponsored a Senate amendment to the State Children’s Health Insurance Program providing one year of job protection for family members caring for soldiers with combat-related injuries.

    Committees

    Obama held assignments on the Senate Committees for Foreign Relations, Environment and Public Works and Veterans’ Affairs through December 2006. In January 2007, he left the Environment and Public Works committee and took additional assignments with Health, Education, Labor and Pensions and Homeland Security and Governmental Affairs. He also became Chairman of the Senate’s subcommittee on European Affairs. As a member of the Senate Foreign Relations Committee, Obama made official trips to Eastern Europe, the Middle East, Central Asia and Africa. He met with Mahmoud Abbas before he became President of the Palestinian Authority, and gave a speech at the University of Nairobi condemning corruption in the Kenyan government.

    2008 presidential campaign

    On February 10, 2007, Obama announced his candidacy for president of the United States in front of the Old State Capitol building in Springfield, Illinois. The choice of the announcement site was viewed as symbolic because it was also where Abraham Lincoln delivered his historic “House Divided” speech in 1858. Throughout the campaign, Obama emphasized the issues of rapidly ending the Iraq War, increasing energy independence and providing universal health care.

    A large number of candidates entered the Democratic Party presidential primaries. The field narrowed to a duel between Obama and Senator Hillary Rodham Clinton after early contests, with the race remaining close throughout the primary process but with Obama gaining a steady lead in pledged delegates due to better long-range planning, superior fundraising, dominant organizing in caucus states, and better exploitation of delegate allocation rules.On June 3, with all states counted, Obama was named the presumptive nominee and delivered a victory speech in St. Paul, Minnesota. Clinton ended her campaign and endorsed him on June 7.

    President George W. Bush meets with President-Elect Obama in the Oval Office on November 10, 2008.

    Obama proceeded to focus on the general election campaign against Senator John McCain, the presumptive Republican nominee, in the lead up to the Democratic National Convention. He announced on August 23, 2008, that he had selected Delaware Senator Joe Biden as his vice presidential running mate. At the convention, held August 25 to August 28 in Denver, Colorado, Hillary Clinton called for her delegates and supporters to endorse Obama, and she and Bill Clinton gave convention speeches in support of Obama. Obama delivered his acceptance speech to over 75,000 supporters and presented his policy goals; the speech was viewed by over 38 million people worldwide.

    During both the primary process and the general election, Obama’s campaign set numerous fundraising records, particularly in the quantity of small donations. On June 19, 2008, Obama became the first major-party presidential candidate to turn down public financing in the general election since the system was created in 1976.

    After McCain was nominated as the Republican candidate, three presidential debates were held between the contenders spanning September and October 2008. In November, Obama won the presidency with 52.9% of the popular vote to McCain’s 45.7%, and 365 electoral votes to 173, to become the first African American to be elected president. Obama delivered his victory speech before hundreds of thousands of supporters in Chicago’s Grant Park.

    First days

    The inauguration of Barack Obama as the 44th President, and Joe Biden as Vice President, took place on January 20, 2009. In his first few days in office Obama issued executive orders and presidential memoranda directing the U.S. military to develop plans to withdraw troops from Iraq, and ordered the closing of the Guantanamo Bay detention camp “as soon as practicable and no later than” January 2010. Obama also reduced the secrecy given to presidential records and changed procedures to promote disclosure under the Freedom of Information Act The president also reversed George W. Bush’s ban on federal funding to foreign establishments that allow abortions.

    Domestic policy

    On January 29, 2009, Obama signed his first bill into law, the Lilly Ledbetter Fair Pay Act of 2009, a response to the Supreme Court’s decision in Ledbetter v. Goodyear Tire & Rubber Co. which eased the requirements for filing employment discrimination lawsuits. Five days later, he signed the reauthorization of the State Children’s Health Insurance Program (SCHIP) to cover an additional 4 million children currently uninsured.

    In March 2009, Obama repealed a Bush-era policy that prevented federal tax dollars from being used to fund research on new lines of embryonic stem cells. Although such research had been a matter of debate, Obama stated that he believed “sound science and moral values…are not inconsistent,” and that we have “the humanity and conscience” to pursue this research responsibly, pledging to develop “strict guidelines” to ensure that.

    On May 26, 2009, Obama nominated Sonia Sotomayor to replace retiring Associate Justice David Souter. Sotomayor was confirmed on August 6, 2009 by a vote of 68-31, becoming the first Hispanic to be a Supreme Court Justice. She joins Ruth Bader Ginsburg as one of two women on the Court and is the third woman ever to be a Justice.

    On September 30, 2009, the Obama administration proposed new regulations on power plants, factories and oil refineries in an attempt to limit greenhouse gas emissions and to curb global warming.

    On October 8, 2009, Obama signed the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act, a measure that expands the 1969 United States federal hate-crime law to include crimes motivated by a victim’s actual or perceived gender, sexual orientation, gender identity, or disability.

    Economic management

    On February 17, 2009, Obama signed into law the American Recovery and Reinvestment Act of 2009, a $787 billion economic stimulus package aimed at helping the economy recover from the deepening worldwide recession. He made a high-profile visit to Capitol Hill to engage with Congressional Republicans, but the bill ultimately passed with the support of only three Republican senators. The act includes increased federal spending for health care, infrastructure, education, various tax breaks and incentives, and direct assistance to individuals, which is being distributed over the course of several years, with about 25% due by the end of 2009. In June, Obama, unsatisfied with the pace of economic stimulus investment, called on his cabinet to accelerate the spending over the next weeks.

    In March, Obama’s Treasury Secretary, Timothy Geithner, took further steps to manage the financial crisis, including introducing the Public-Private Investment Program, which contains provisions for buying up to $2 trillion in depreciated real estate assets that were deemed to be weighing down stock valuations, freezing the credit market and delaying economic recovery. On March 23, The New York Times noted that “(i)nvestors reacted ecstatically, with all of the major stock indexes soaring as soon as the markets opened.” Along with spending and loan guarantees from the Federal Reserve and the Treasury Department, about $11.5 trillion had been authorized by the Bush and Obama administrations, with $2.7 trillion actually spent by the end of June 2009.

    Obama intervened in the troubled automotive industry in March, renewing loans for General Motors and Chrysler Corporation to continue operations while reorganizing. Over the following months the White House set terms for both firms’ bankruptcies, including the sale of Chrysler to Italian automaker Fiat and a reorganization of GM giving the U.S. government a temporary 60% equity stake in the company, with the Canadian government shouldering a 12% stake. He also signed into law the Car Allowance Rebate System, known colloquially as “Cash for Clunkers” bill, on August 7, 2009.

    In the third quarter of 2009, the U.S. economy expanded at a 2.8% annual pace. Obama has claimed that the stimulus package helped stop the economic downturn. Various economists have credited the stimulus package with helping to create economic growth.However, unemployment has continued to rise to 10.2% (the highest in 26 years and the “underemployment” rate rose to 17.5%. In mid-November, Obama said he was concerned that the excessive deficit spending could cause the economy to slide into a “double dip” recession.

    What is GAMES??? 

    A game is a structured activity, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more concerned with the expression of ideas. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong solitaire).

    Key components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational or psychological role. According to Chris Crawford, the requirement for player interaction puts activities such as jigsaw puzzles and solitaire “games” into the category of puzzles rather than games.

    Attested as early as 2600 BC, games are a universal part of human experience and present in all cultures. The Royal Game of Ur, Senet, and Mancala are some of the oldest known games.

    Honda’s first engine CVCC (what is CVCC) 

    CVCC means Compound vortex controlled combustion.The CVCC engine debuted in 1975. Offered alongside the standard Civic engine, the 53-horsepower CVCC engine displaced 1,488 cc and had a head design that promoted cleaner, more efficient combustion. The CVCC design eliminated a need for a catalytic converter or unleaded fuel to meet emissions standards. (Nearly every other U.S. market car for this year underwent the change to exhaust catalysts and the requirement to use only unleaded fuel.) Due to California’s stricter emissions standards, only the Civic CVCC was available in that state. A five-speed manual gearbox became available this year, as did a Civic station wagon (only with the CVCC engine).

    A CVCC engine has a special cylinder head. The CVCC head uses a stratified charge combustion chamber. A stratified combustion mixture is richer at the sparkplug and much leaner at the main part of the combustion chamber. The rich mixture is easily ignited by the sparkplug and this initial flame will ignite the remaining leaner mixture. The CVCC head uses a pre-combustion chamber that is about the size of a thimble. The CVCC carburetor is actually two carburetors in one, a lean part and a rich part. The lean part feeds the main combustion chamber and the rich part feeds the pre-combustion chamber. The rich mixture in the pre-combustion chamber is ignited . A “flame hole” in the pre-combustion chamber allows the pre-combustion flame to blow across the regular combustion chamber and ignite the lean mixture.

    How to identify a CVCC:
    -1500cc engine, designated ED1
    -They say CVCC on the rocker cover
    -The hose for the air filter goes to driver’s side fender
    -2.17″ length increase in the front fenders to accommodate the larger CVCC engine
    -Water pump is on the back drivers side and alternator is on the front
    -3 spoke steering wheel (either wood grain or black)
    -5 speed CVCC’s have a deluxe gauge cluster- Tach/Speedo and Fuel/Temp gauges on the center of the dash
    -Hood has a split scoop type vent in front of the wind shield on later models.
    -Rear struts on the hatch & coupe models are straight and similar in design to the front. Un-likethe 1200 models have a U-shape bracket welded to the bottom.

    How The CVCC Engine Operates

    Suction Stroke
    On the intake stroke, a large amount of very lean mixture is drawn through the main intake valve into the main combustion chamber. At the same time, a very small amount of rich mixture is drawn through the auxiliary intake valve into the pre-chamber.

    Compression Stroke 
    At the end of the compression stroke, a rich mixture is present in the pre-chamber, a moderate mixture is formed in the main combustion chamber near the pre-chamber outlet, and a very lean mixture is present in the remainder of the main combustion chamber.

    Ignition
    When the spark plug fires, the rich mixture in the pre-chamber is easily ignited.

    Expansion Stroke
    The flame from the pre-chamber ignites the moderate mixture and this, in turn, ignites the lean mixture in the main combustion chamber. The formation of carbon monoxide is minimized because of this lean mixture.

    Bottom Dead Center 
    The stable and slow burning in the main combustion chamber has two desired effects. The peak temperature stays low enough to minimize the formation of oxides of nitrogen. And the mean temperature is maintained high enough and long enough to substantially reduce hydrocarbon emissions.

    Exhaust Stroke
    The hot gases exit through the exhaust valve, and oxidation continues in the manifold.
