Small Business in the United States

It is a common misconception that the U.S. economy is dominated by huge corporations when in fact roughly 99 percent of all independent enterprises in the country employ fewer than 500 people, meaning small businesses technically dominate the market in the United States, accounting for 52 percent of all workers according to the U.S. Small Business Administration (SBA). According to the United States Department of State, some 19.6 million Americans work for companies employing fewer than 20 workers, 18.4 million work for firms employing between 20 and 99 workers, and 14.6 million work for firms with 100 to 499 workers; by contrast, 47.7 million Americans work for firms with 500 or more employees. Customers Appreciate the Interactivity and Accountability Of the many reasons small businesses traditionally do so well in the United States economy is their readiness to respond to changing economic climates and situations, wherein customers appreciate the interactivity and accountability of small businesses to their local community wants and needs. Similarly, building a small business has always been a backbone of the American dream, so it stands to reason a lot of small businesses were created in this pursuit. By the Numbers With just over half of the American workforce employed by small businesses — those with under 500 employees, small businesses produced over three-fourths of the economys new jobs between 1990 and 1995, which was even larger than their contribution to employment growth than in the 1980s, though slightly less than 2010 to 2016. Small businesses, in general, provide an easier entry point into the economy, especially for those facing a disadvantage in the workforce like minorities and women — in fact, women participate perhaps the most heavily in the small business market, where the number of female-owned businesses rose 89 percent to 8.1 million between 1987 and 1997, reaching over 35 percent of all sole proprietorships by the year 2000.​ The SBA specifically seeks to support programs for minorities, especially African, Asian, and Hispanic Americans, and according to the Department of State, in addition, the agency sponsors a program in which retired entrepreneurs offer management assistance for new or faltering businesses. Small Business Advantages Over Corporations One of the greatest strengths of the small business is its ability to quickly respond to economic pressures and local community needs, and because many employers and owners of small businesses interact with their employees and are active members of their local communities, company policy is able to reflect something much closer to the local ethos than a major corporation that comes into a small town. Innovation Is Prevalent   Innovation is also prevalent amongst those working in small businesses compared to major corporations, though some of the tech industrys biggest corporations started out as tinker projects and sole proprietorships, including Microsoft, Federal Express, Nike, America OnLine and even Ben Jerrys ice cream. This doesnt mean that small businesses cant fail, but even the failures of small businesses are considered valuable lessons for entrepreneurs. According to the United States Department of State, Failures demonstrate how market forces work to foster greater efficiency.

Security Issues Of Wireless Sensor Networks - 1286 Words

Security issues in Wireless Sensor Networks What the security issues are related to Wireless Sensor Networks Name:Sandeep Kumar Pulijala Student ID:S0261345 Teacher:Erin Class:DEA3 Central Queensland University What the security issues are related to Wireless Sensor Networks Wireless sensor networks are very important in everyday life. This new technology is exciting with unlimited potential for numerous application areas including environmental, medical, military, transportation, entertainment, emergency management and homeland defence. WSN are connected with nodes, in WSN communication takes place through air. The exploration subject that I have picked is on Wireless†¦show more content†¦An extension of this approach is in-network aggregation which aggregates data progressively as it is passed through a network. In-network data aggregation can reduce the data packet size, the number of data transmissions and the number of nodes involved in gathering data from a WSN. Therefore, in the field of WSNs, privacy-preserving data aggregation is becoming a hot issue in WSNs. To address this issue, some protocols have been proposed. In this, they provide a comprehensive summary and comparison of the existing privacy-preserving data aggregation protocols for WSNs. WSN is related to privacy-preserving data aggregation protocols (Ping et al 2012). In the authors reviewed privacy-preserving techniques for protecting two types of private information: data-oriented and context-oriented privacy. First, authors focuses only on data privacy in order to provide detailed overviews of the existing privacy-preserving data aggregation protocols for WSNs (Ping et al 2012). Two main security challenges in secure data aggregation are confidentiality and integrity of data (Sugandhi et al 2013). While traditionally encryption is used to provide end to end confidentiality in Wireless Sensor Network (WSN), the aggregators in a secure data aggregation scenario need to decrypt the encrypted data to perform aggregation.

”Black Heroes of American Revolution” by Burke Davis Essay Sample free essay sample

The book I read for the enriched history undertaking was Black Heroes of the American Revolution by Burke Davis. The ground I chose the book was because after looking at some of the books I thought I would be most interested in this 1. On Revolutionary war twenty-four hours. there was a re-enactor of Edward Hector who told us much about African American soldiers. I have ever been fascinated with African American History and wanted to cognize more about the soldiers Edward Hector talked approximately. Another ground I chose this book was because it was straight to the point alternatively of pages of filler it talked about who. when. where. and why with feeling. This book was chiefly written to inform readers about how many African American people fought and died for the American Revolution. The Author stated how 2 and 1 half million people lived in the settlements during the radical war and half a million of them were black. We will write a custom essay sample on †Black Heroes of American Revolution† by Burke Davis Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page After the war 60. 000 African Americans were set free because they helped win the nation’s freedom. Although the efforts of many African Americans were non recorded we still know of some celebrated African Americans of the war because of people like John Greenleaf Whittier a white poet who wrote about African American History. John Greenleaf Whittier peculiarly praised the establishing male parents that were African American. One of the people in this book that the writer peculiarly emphasized was William Lee. William Lee is non a name known by most Americans but he was at the side of General Washington sharing every minute of the American Revolution with him. William Lee was besides General Washington’s closest comrade before and after the war. General Washington subsequently gave William his freedom and money for him to populate in his old age. Another individual the book emphasized was Edward Hector ( the soldier from radical war twenty-four hours ) . Edward Hector was an artillery adult male who was really courageous and most celebrated for a conflict at Chadds Ford. At Chadds Ford. Sir William Howe marched 17. 000 British and German military personnels toward Philadelphia. General Washington set up his soldiers along the Brandywine Creek. in confusion 1. 000 of Washington’s work forces fled in terror. Edward Hector was still pouring shootings into enemy ranks. Even after being told to abandon his heavy weapon waggon that he had merely pulled into conflict. he still fired and made his most celebrated quotation mark â€Å"I’ll neer leave! I’ll salvage my Equus caballuss or decease myself! † Amidst the confusion. Edward Hector calmly gathered up a few bases of weaponries and safely returned with the waggon. The most of import radical war hero talked about in the book was twenty two twelvemonth old James Armistead. James Armistead was the slave of William Armistead and volunteered to be a soldier to General Lafayette to seek and claim freedom. At the clip General Benedict Arnold and Lord Cornwallis were in Virginia plundering the streets. General Lafayette followed both of the little British ground forcess without doing conflicts. But what General Lafayette truly needed was a undercover agent. General Lafayette called upon James Armistead to be his undercover agent. James Armistead so went to Benedict Arnold’s cantonment and volunteered. James Armistead was neer suspected to be a undercover agent as he was a immature smiling black adult male who merrily served the British. James Armistead would subsequently be known as the maestro undercover agent of Yorktown. James Armistead frequently served Lord Cornwallis and Benedict Arnold dinner and as they were discoursing programs James w ould merely smile and feign non to cognize what they were speaking approximately. Within hours of James hearing these programs they would make General Lafayette. James Armistead was so given a certification by General Lafayette praising his work. James Armistead took this certification to the General Assembly of Virginia and declared to be a free adult male. After being declared a free adult male he changed his name to James Lafayette. I truly enjoyed reading this book. I liked this book for many different grounds. One of the grounds I enjoyed this book was because it depicted many war and conflict scenes. Another ground I enjoyed this book was because I had no thought how many African Americans really fought for the American Revolution. I ever thought they were all slaves. This book besides informed me of many different war heroes that were African American and what they did. I would urge this book to other people looking for a book of this type.

Global warming essay free essay sample

Global Warming essay Global warming, a largely discussed topic. Many people would argue that global warming is dangerous and is a big problem to the earth and the enviroment. Although these people have a very good point on the subject, you have to realize the cause of global warming and how there is a lot of evidence that is false and exaggerated. You also have to realize that us man-kind control the impact, and the extent to which it will alter our climate. Many people can argue different opinions on this subject, such as, they can think it is a serious threat and that it will impact all parts of our society and that action needs to be taken immediately to abate the effects. Others may believe that global warming isnt true, and all actions taken toward it will only cause harmful effects to the economy. In my standpoint, I believe that global warming isnt a problem. We will write a custom essay sample on Global warming essay or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I stand in the position that its not a big deal, and people and scientists are exaggerating the facts. Many scientists say it is CO2 causing the global warming. For example the saying â€Å"reducing your carbon footprint† Yet simply in the article â€Å"No Need to Panic About Global Warming† It states that CO2 is not causing as much damage as other scientists might say. Rather they are only basing their theories upon a computer where they amplify and exaggerate the effects of CO2. As they state in the article â€Å"the warming is only missing if one believes computer models where so-called feedbacks involving water vapor and clouds greatly amplify the small effect of CO2. † so the computers dont eaxctly know what will happen in the future they only can predict upon what has happened. So therefore what the computers hypothosize, is most likely not correct because of the changes in precipitation, water vapor, and clouds. Another reason is, â€Å"that computer models have greatly exaggerated how much warming additional CO2 can cause† they are only basing what they get off of the computer and not realizing that CO2 isnt as bad as they believe. Simply these scientists that believe the global warming isnt a big deal are stating that the world is heating up mostly by itself, because CO2 isnt a pollutant, its a colorless, orderless gas, that is a key element in the biospheres life cycle. They stae that CO2 helps aide growth in plants, and have better variaties. In the studies of global warming, they saw a small rise in temperature during the second half of the 20th century. The one part in this is the natural CO2 emmisions, and that humans only have a third of the role of the increase of it. So the benifiets of moderate warming are likely to outweigh the effects. Scientists say that CO2 causes a small amount in moisture, that would cause further warming, but others have found no evidence as such. So without this added information there is no crisis, because even if the earths temperature continued to rise, it would only increase 0. 123 degrees C per decade. Some scientists even have evidence of a cooling trend. Which contradicts the major role of CO2. Many people state that global warming increses the amount of catastrophic concequences, but there isnt a sufficient amount of evidence the trend to be true. It should have shown an increase in the 20th century, but it didnt. As I mentioned above, the rise of CO2 would help fertilize and increase the growth of the plants and amount, and also more rain. So you would be gaining a lot in produce and farming. As mentioned in the atricle â€Å"How Will Global Warming Change Earth†. Other then that the rising of seas are disscused to, but the rising in the waters more then serveral inches are proven by data that it is unlikely. It would have little effect on wildlife, but it even has a positive effects such as, hurricanes would decrease in the frequency and sevarity. Although many scientists and people agree upon global warming being a crisis, it is matter a fact not. The increase of CO2 would greatly benifeit us in many ways. Global warming just doesnt have enough liable evidence that it is a crisis, information is exaggerated and is only a theory from a computer. Even several pieces of evidence state that our earth is in a cooling trend. So even though many people are arguing that it is a problem, it would only be a problem if carbon increased by humans significantly. So, with the evidence as is, there is more proof that its not as big as a problem as we might think.
