Martin Cooper was already working on the development of making the first cell phone working as a general manager for Motorolas Communications System Division. He claims he was inspired one day while watching Star Trek when he saw Captain Kirk use his communicator. He then worked on it till one day in 1983 he made his first phone call from his mobile phone to his buddy at ATT and told him Motorola was going to change the game. The first mobile cellphone he made was the Motorola Dynamic 8000x that weighed about 2.5 pounds with just one single line coming in and a text only LED screen, being as big as it was battery life only lasted for about 20 minutes. It went for about four thousand dollars to consumers, and at that time only celebrities were able to really afford the phone. In his mind, he wanted everyone to own a phone in the near future.

Our writers will create an original "Depiction Of Cellphones Evolution" essay for you Create order Demand on cellphones was becoming more and more popular to the general public that by 1990 the 2G digital cellular network was invented and more cellphone tower sites were starting to pop up. Around this same time the first SMS was sent as well. Fast forward to 2001 Japan was the first country to have a 3G network while the US followed by 2003. According to Tim Brookes 3G transformed the mobile phone industry and enabled widespread mobile internet and transmission services like TV and radio. Once these innovators from cellphone companies saw the fast progress they were making with 3G they were ready to get into the next step. They knew they were just getting better but even their highest speed wasnt attainable unless you were in the right spot at the right time. By this time SMS and the internet was very popular so they were trying very hard for to come with a faster network which was 4G LTE. Most cellphone companies today offer LTE or 4G LTE. Though they both are faster than 3G network. 4G offers consumers that stream TV or music faster speed while 4G LTE is a type of technology that delivers the fastest speed. The only problem is that it is not offered by every carrier and before purchasing a cellphone with that network you would have to check that carriers coverage map and you would have to be in an area where they must support it according to Angela Stringfellow. Not only did the technological part of the cellphone change but the physical design itself. cellphones back then were very bulky and heavy as the first computers. But like computers and laptops cellphones have gotten relatively smaller. Once cellphones became mainstreamed in the 90s customers complained about cellphones being too small and the buttons being too big that it interfered with everything else but with the time passing their perception changed and they requested smaller and sleeker phones. Now a day they have a huge variety when it comes to phones, most have larger screens with less buttons or no buttons at all giving it a more personal laptop feel to it. With the cell phone in itself developing so rapidly, now we are able to use it while were driving hands-free by simply speaking into something we have now call Siri, we can ask it to send a text or a call, even as far as telling it play a song without even putting our hands on our mobile phones. We are also able to take professional pictures because of the advancement camera phones have made. Before we had to have a digital camera to be able to take quality pictures. Creators then started playing around megapixels and sensors to create better quality pictures in the cellphone. Lens quality, image signal processor and the camera software plays a huge part in the camera quality as well. And according to the book Converging Media Director Malik Bendyellow used his iPhone to finish shooting a movie he was filming because he had run out of money to pay for 8mm film. Thats when they knew cellphones were going to be revolutionary. Lastly, we can all agree that cellphones have come a long way from being a bulky one line text only screen, to where we were able to do basic things like send texts and take ok quality pictures till now where they are more sleeker and have less buttons and still be able to stream videos and music, take great quality pictures, download apps, facetime with one or multiple people at a time. So many great things we got out of the invention of the cellphone and the future holds a lot more.

Historical Heritage And Regional Identity - 1732 Words

When does the symbol of someone’s historical heritage and regional identity become unacceptable due to the same symbol being found offensive and representative of the oppressed heritage of someone else? Recently at the University of Mississippi the topic as to continue flying the state flag was put to a vote. The Associated Student Body voted to remove the flag from any and all buildings on campus; the chancellor ultimately decided that the Associated Student Body was right in this decision. The appropriateness of the Confederate flag has become a major point of dispute in this country. In the state of Mississippi, however, the argument is complicated by the fact that the state flag itself incorporates the Confederate flag into its†¦show more content†¦These people believe it’s preventing businesses and athletes from coming to our state, and that it’s time for a change. The critics of the state flag have pushed for the Confederate symbol to be remov ed from the state flag for many years before it became a hot topic at the University of Mississippi. People who oppose the current state flag believe the Confederate design embodies the evil that was the southern states before and during the Civil War (International Business Times). Mississippi is one of the last states, which were a part of the Confederate States of America; to remove the Confederate symbols from representative objects (Confederate Flag Debate CNN). The University of Mississippi is the fourth college in the state to stop flying the state flag on campus (Ole Miss Student Senate). The symbol of the Confederate Battle Flag has been adopted as a representation of groups who resort to nefarious actions to promote a malicious agenda. The original intent of promoting the heritage represented by the flag has been replaced by racist and oppressive actions perpetuated by its banner. Many people have had negative experiences with the Confederate symbol. One man recounts a time when he first saw the Confederate flag as an indication of hate; he remembers being about twelve years old watching Ku Klux Klan members entomb an acquaintance while carrying the Confederate flag (Confederate Flag Debate CNN). The University of Mississippi’s student body has just

Pathophysiology on Cardiogenic Shock free essay sample

Cardiogenic shock is characterized by the heart’s acute inability to deliver the amount of oxygen that the peripheral tissues and organs demand. [DCCN 2008] Patho psychology of Cardiogenic Shock When a critical mass of ventricular myocardium becomes ischemic or necrotic, the ventricular pump fails, and there is a decrease in stroke volume and cardiac output. Decreased stroke volume causes increased filling pressures and wall tension for the left ventricle, with a corresponding increase in myocardial oxygen demand. The increased filling pressures are reflected back into the left atrium and the pulmonary vasculature, leading to vascular congestion and pulmonary oedema with impaired gas exchange. The acute decrease in cardiac output can result in multi organ failure and systemic inflammation. As hypotension occurs because of the decrease in cardiac output, the aortic diastolic pressure is also decreased, compromising the coronary artery perfusion and decreasing oxygen delivery to the myocardium. With a decrease in cardiac output, the heart rate increases, further decreasing diastolic time. We will write a custom essay sample on Pathophysiology on Cardiogenic Shock or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In response to the decrease in cardiac output, there are several compensatory mechanisms that activated. The sympathetic nervous system causes an increase in heart rate and systemic vascular resistance (SVR) in an attempt to increase blood pressure and maintain cardiac output, whereas the rennin-angiotensin-aldosterone system causes the retention of sodium and water to increase blood volume and preload. Tachycardia further compromises coronary perfusion as well as the perfusion to the left ventricle. The pre-existing ischemia is worsened, and the downward spiral that characterizes cardiogenic shock begins.

The Dangerous Allure of the 70

Problem Identification In everything that one sets to do, there is need to ensure that it is done in the expected manner. Acting within expectation is what defines an accomplished worker from an ineffective individual.Advertising We will write a custom case study sample on The Dangerous Allure of the 70-Hour Workweek specifically for you for only $16.05 $11/page Learn More Because of the increasing demand in every sector of the economy, there is always the need to work beyond the planned timeline. It would be appropriate that the workforce appreciates the importance of this. However, a crop of individuals has developed a character that is very dangerous to their well-being. These individuals work in excess of 70 hours per week. Some go beyond this to work for about 100 hours a week. Hewlett and Luce (2006) note with concern that some go overboard to work for a record 120 hours a week. Although it is a sure way of becoming rich, the practice comes with so me serious consequences. Such individuals, irrespective of their gender, put their health at risk. Cunningham (2000) cautions that taking much time without rest and exercise makes the body vulnerable to various health complications. Besides this, an individual who does not allocate his time appropriately between work and family would create an environment where their families would lose touch with him or her. Another concern that this current trend has is the inability to manage other social duties. Individuals who take almost all their available time on career related issues may find themselves being social misfits in the society. Cunningham (2000) observes that they may excel in their offices and workplaces but may not be in a position to respond to other social concerns.Advertising Looking for case study on social sciences?

Get your first paper with 15% OFF Learn More Situation Analysis The current generation worker force is industrious and is always determined to accomplish duties at hand before the set time so that they get into other duties. However, the situation as it stands now is very dangerous. Many executives are working beyond the normal set time. This trend cuts across professions and sectors of the economy. As one climbs the career ladder, the need to do more than the normal duty increases. It is understandable that the current corporate world is placing a lot of pressure on few selected individuals in their quest for a leaner workforce. However, it is not appropriate that one is allocated duties that would completely make him or her lack time at all for the family. Giddens (2009) says that some duties would turn an individual into a zombie. One works without the realization that there is a family to take care of. This has seen many families break. Some spouses may not withstand a scenario where they are not given any time with their partners. This explains in part the reason behind the recent rise of single parenthood, especially among the corporate men and women. Children who find themselves in such situations grow up to be very irresponsible. They lack parental care that every child would require for a normal growth. Other than the social consequences, one exposes himself or herself to many health risks by taking much of his or her time on various duties related to their career. As Hewlett and Luce (2006) report, some people would work in excess of 120 hours in a week. On average, this leaves an individual with approximately six hours per day to commute, eat, and socialize. This on average leaves an individual with about two to three hours to sleep. As Andrzej and Buchaman (2007) observe, it is important that an individual sleep for at least six hours a day. Taking two hours to sleep would make one develop serious health complications. Coupled with the fact that in some of the cases an individual may take most of the time seated, one would be exposed to both physical and menta l dangers. If the body were not given time to relax and exercise, then it would fatigue and develop complications that would be avoided if proper measures were taken.Advertising We will write a custom case study sample on The Dangerous Allure of the 70-Hour Workweek specifically for you for only $16.05 $11/page Learn More Recommendation It is recommended that one should make an effort to ensure that his or her responsibility is undertaken within the right time and with precision that is expected. However, it would not be appropriate if one engages in duties that cause total neglect to the family. One’s career is important but it should not be overemphasized at the expense of the family. There should be a balance between the two. Below are some of the ways in which one can ensure that he or she strikes a balance between social issues and job related duties. Planning is the main tool that an individual can use to ensure that he or she balances soci al duties and work. An individual should take time to lay down duties before him or her. The individual can then look at the time available to achieve the obligations. The individual should allocate time to each work in a way that would still allow him or her to obtain some time to be back to the family and meet some other social obligations. The planning would help an individual know the amount of time that would be required to meet various obligations. After making the plan, it is highly advisable that such an individual strictly sticks to it so that no obligation is given more time than was planned. Although this may force one to take lesser time at workplace, it is the only way of managing the attention needed at work and at home. Taking duties that are within one’s scope is another technique that can be applied to manage time. It is good to be ambitious. However, there is need for one to understand his or her scope. It is important that an individual appreciate his or he r limits beyond which working will be strenuous. After this realization, it would be necessary that the individual take duties that are within his scope. It would help in avoiding circumstances where one is forced to work beyond the limits, forcing one to shelve time that would be spent with the family.Advertising Looking for case study on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More The family is just as important as the career. As one aspires to achieve the best out of his or her career, it is important to note that the family also has a place. Neglecting one’s career would be dangerous as it may lead to poor yields, a fact that may lead to consequences that one could not have prepared for at work place. Similarly, assuming the family would lead to lose of touch between the parent and the family. Children need parental attention in order to develop normally. If this is reality is not identified, such children may develop to be irresponsible individuals in society who are not what the parents would have expected them to be.
