The Christmas Carol by Charles Dickens Essay Example For Students

The Christmas Carol by Charles Dickens Essay Humbug!? was Scrooges favorite answer to any question and any question was an inappropriate question to the grumpy old covetous man. Depicted in the ethical story, The Christmas Carol, by Charles Dickens, Scrooges fowling manner transformed his once passionate heart to a black hole, which pulled in all hope and happiness as if it were a powerful magnet. Nevertheless, the jar of hatred shattered and Scrooges impaired spirit rose again. Love and happiness permeated his body, and the once ignorant Scrooge developed into an irresistible congenial fellow that everyone now knew. Scrooge found that he had the ability to alter his behavior and realized that spreading Christmas was more rewarding than any given amount of money. Scrooges capability to transform himself from a wrenching, disgruntled man to a blithe, amicable friend was surprising to the inhabitants of the small city. For instance, Charles Dickens wrote, Some people laughed to see the alteration in him , but he let them laugh, and little heeded them- (page 112). Scrooge didnt mind the giggles and laughs directed at him because he believed in himself for the first time in a very long time. We will write a custom essay on The Christmas Carol by Charles Dickens specifically for you for only $16.38 $13.9/page Order now His confined spirit was freed at last and it allotted happiness and joy around from mysterious turkeys on the doorstep to charity donations. Scrooge sought to make the people of the city cheerful and in doing so, people enjoyed watching an old jolly man hop around delivering gifts. Thus, Scrooge did not heed to the snickers in the crowd. The joy of spreading Christmas was Scrooges indirect gift to mankind and it rewarded him with long-lasting friends, which could never compare to any wealth. For example, Charles Dickens wrote,? He became as good a friend, as good a master, and as good a man as the good old City knew, or any other good old city, town, or borough in the good old world(page 112). This quote portrays that Scrooges contribution all year round achieved the worlds love and benevolence he longed for. In addition, Scrooge tried hard to become a role model to all; he funded charities for those in need and medical bills for Bob Cratchits son, Tiny Tim. Therefore, Scrooge reveals his exuberant and respectful manners earning him love from humanity. Scrooge loved and hated the three ghosts he met. He was thankful for their kind thoughts to help him, but despised them for recalling memories that he wished were of no existence. Are these the shadows of the things that Will be or shadows of things that May be, only (page 102). Scrooge in time understood that he had the power to set his future any way he wanted. He could be grumpy for all time and be forgotten or be giving and considered as a hero. Also, Scrooge learns that life should not be taken for granted, but treasured for every moment because he only has one chance to live. Indeed, Scrooge was grateful that he was given a second chance to alter his one life. In conclusion, The Christmas Carol reveals that Scrooge had misguided himself in his early life, but eventually placed himself back onto the right road again. Scrooges life will be forever changed by his commitment to spreading Christmas and joy all year. As a second father to Tiny Tim, Scrooge becomes part of the poor Cratchit family and will help supplement them through harsh events. All in all, Scrooges cookie jar of hatred broke, and out escaped his confined spirit filling the air with hope and happiness, re-defining the meaning of Christmas again.

How to Make Complaints for ESL Students

How to Make Complaints for ESL Students Politeness is universally appreciated, even when making complaints, no matter what language a person speaks, but in learning English as a Second Language (ESL), some students may struggle with formulas and functions of certain English phrases meant to politely start a conversation involving a complaint. There are a number of formulas used when complaining in English, but its important to remember that a direct complaint or criticism in English can sound rude or aggressive. For most  English speakers, its preferred that others express their dissatisfaction indirectly, and introduce the complaint with an amicable introductory clause such as Im sorry to have to say this but... or excuse me if Im out of line, but... It is important to note, however, that these phrases dont directly translate into Spanish so understanding the basic function of words like sorry go a long way to introducing ESL students to the polite way to go about making complaints in English. How to Start Complaints Amicably In Spanish, one might start a complaint with the phrase lo siento, or Im sorry in English. Similarly, English speakers typically start their complaints with an apology or indirect reference to propriety. This is largely because politeness is a major element of English rhetoric.   Some phrases that English speakers may use to start complaints politely: Im sorry to have to say this but...Im sorry to bother you, but...Maybe you forgot to...I think you might have forgotten to...Excuse me if Im out of line, but...There may have been a misunderstanding about...Dont get me wrong, but I think we should... In each of these phrases, the speaker begins the complaint with an admission of error on the speakers part, relieving some of the assumed tension between speaker and audience by letting the listener know that no one involved is blameless. Whether it be because of  contrasting ideas  or just because a speaker wants to say no nicely, these introductory phrases can be helpful to maintain respectful rhetoric in conversation. Forming a Polite Complaint After ESL students understand the concept of introductory phrases to complaints, the next important element of conversation is keeping the complaint itself polite. Although being  imprecise or vague  does have its benefits when complaining, clarity and good intentions go a lot further in maintaining the cordiality of conversation. Its also important not to come across as attacking while making a complaint, so the complaint itself should start with phrases like I think or I feel to indicate that the speaker isnt accusing the listener of something as much as he or she is starting a conversation about the disagreement. Take, for instance, an employee who is upset at another for not following the company policy while working at a restaurant together, that person might tell the other Excuse me if Im out of line, but I feel like you may have forgotten that closing waiters need to refill the salt shakers before leaving. By introducing the complaint with an apology, the speaker allows the listener to not feel threatened and opens up a conversation about company policy instead of scolding or demanding that person do their job better. Redirecting focus and calling for a solution at the end of a complaint is another good way to address the issue. For instance, one might say Dont get me wrong, but I think it might be better if we focus on this task before doing the one youre working on to a coworker who is not working on the right part of a project.

A short story based on the Missing In Action film trilogy Essay

A short story based on the Missing In Action film trilogy - Essay Example Every crumbling building reminded him of America’s shameful capitulation. The freeway was patched and torn, and distinctive Vietnamese army trucks rattled towards the Gook headquarters in Pioneer Square. Raucous cries from the sleeping quarters disturbed his thoughts and he turned to see what was causing the fuss. One of the ragged band was throwing punches at the Colonel and the rest were laughing and jeering, Braddock stood there, impassive, while the little guy danced around him spitting and shouting all the while. It was just the usual pointless play fighting. You would think they had had enough of that in ‘Nam. He looked pitiful in his torn combat fatigues. Nester sighed and turned his back on the prisoners. He was all there was between them and a Vietnamese execution squad but they still didn’t get it. At this rate the Gooks would kill them all. Braddock was watching quietly in that spooky way of his. Nester couldn’t understand why he didn’t act like a leader. Most of the time the men did whatever they liked, and he just let them do it. Nester carried on his way past the untidy collection of small white crosses. They reminded him of the cemetery back home where his father lay. He could hardly be further away from his Mississippi childhood than he was now. Winter was approaching fast and he was not looking forward to the cold winds from the sea and the Northern snows. All ideas of glory and victory seemed like a hopeless fantasy. His job was to survive and use his wits to keep the others alive, even if they hated him for it. In the distance the thud, thud of a chopper could be heard. Someone shouted out â€Å"Sounds like an American!† and everyone looked at Braddock. He inclined his head to the right and everyone scrambled towards the makeshift parade ground. The guards started shouting in that high-pitched squawk that passed for a language and gestured to Nester. They expected him to

Ethics and Corporate Accounting Practices Research Paper

Ethics and Corporate Accounting Practices - Research Paper Example It is the structure with the help of which the objectives of the company are developed and means for attaining those goals and objective and ways of monitoring them are determined. In this scenario the role of ethics is well understood. Ethics is the moral philosophy, which involves systematic study of honest obligations, agreements, values and rules (Bloxham, 2011). Ethically carrying out the business operation in organizations is a general norm that prevails since the ancient ages. However, ethical norms or governance in case of financial reporting is a comparatively new concept, which is further transformed due to the challenging global business scenario. The major article that has been selected for this study is â€Å"Corporate governance and sustainability: New and old models of thinking†, by Eleanor Bloxham published in 2010. It discusses the traditional as well as latest significance of corporate governance in organizations. Apart from this, the transformations of the f inancial models with the changing times have been also stated. However, there are other supporting articles that have been utilized in this study in order to present a 360 degree view of corporate governance and its impacts. ... Apart from this, the role and usage of technology in financial record-keeping would be scrutinized, so as discuss the strengths and weakness of the IT based infrastructure in corporate governance. CRITICAL EVALUATION Responsibility of Corporate Governance The responsibility of corporate governance does not lie only on the shoulders of the managers in the organization. Before focusing specifically towards corporate governance in case of financial decisions making, a brief discussion on the stakeholders of the organization that are also responsible for maintaining ethics and governance in the organization would be presented in this section. There are approaches around the world based on which the role of the shareholders in corporate governance has been defined. In countries like UK and US, the corporate governance norms focus on maximizing the wealth of the shareholders through efficient means off course. However, in the primacy approach the shareholders are treated as stakeholders wh ere directors have the legal enforcement to consider the duties of the shareholders. From the economic perspective, shareholders are the risk bearers for the company. While another approach states that shareholder's primacy should be followed and directors are primarily accountable to the shareholders (Hib, 2012). Board of directors holds the major position in case of corporate governance. They are accountable to the stakeholders and primarily to the shareholders of the company. The board also focuses on the performance of the organization and the board. The management is responsible for the sustainability by enhancing the enterprise value of the company and also directs the company towards its corporate objective. It is the

Personal Philosophy (Mission Statement) Essay Example | Topics and Well Written Essays - 1000 words

Personal Philosophy (Mission Statement) - Essay Example Amidst all frustrations in life, optimism is essential. Everything can be achieved if we remain positive. With sufficient determination, we can climb the highest of mountains. That cannot be achieved in the absence of faith. Philosopher Henry David Thoreau once said, "If one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with success unexpected in common hours." We cannot afford to lose hope and faith. Hope and faith may only seem a simple word but they are the tower of strength in times of anxiety and despair. My spirituality remains extremely important in my life; it is the backbone of my inner self. I am basically a simple person who appreciates the goodness of life. One of the things I enjoy is watching movies. Films are both entertaining and educating. Whether captured from actual accounts or just purely fictional fragments, they depict reality and display the expanse of man's imagination. I have always been amazed at man's cleverness in producing movies. I constantly look forward to meeting new people. It gives me a sense of excitement. Perhaps it's because this is a very big world and it is probably impossible to meet all the six billion plus people inhabiting earth. I always find something interesting in the diversity of man's character. And I have proven that whatever color we may be, beyond the variety of race and culture, beneath the skin we are all the same; we are brothers and sisters. Whenever I feel exhausted from everyday routines, I go shopping. When it comes to relaxation, shopping is indeed a pleasant diversion. I also found out that until now I am fond of exploring new things. I guess that the curious little child in me never grew up. Many things capture my interest and I don't stop until I learn about them and then put them to good use. There are quite a few things I wish to change about myself. Some say that I have a little attitude and that I easily get angry. Perhaps that is because I am far from my country and that I miss my family and friends very much. Sometimes I also easily get impatient. I get annoyed when things get delayed and not done right away. Personal, Academic, and Career Goals Coming from a small family of four, it is my dream to have a large family. I intend to stay with my husband for the rest of my life and be able to provide my kids a happy life and good education. I also want to stay close with my parents and only brother. I aspire to have a 4.0 GPA and get my bachelor degree sooner than expected and start my MBA soon after. I believe that I would need all the skills I can acquire to competently manage my mother's business. I plan to make many changes and practice the theories I have learned. Strengths and Weaknesses I am happily married and have just recently given birth to a healthy baby boy. Even from the womb, he is my inspiration. He is definitely one of my treasures in this life. My son embodies the love that has flourished between me and my husband. My son provides in me the strength to desire a better future for my family. I am not a very patient person but having a child gradually remedies that. Caring for an infant requires patience and my love for my

Overview of Green Wireless Networks

Overview of Green Wireless Networks Abstract: Traditional mobile networks largely focus on availability, variety, stability and large capacity. Due to the rapid development of Information and Communication Technology (ICT) industry whose major constituent are the mobile networks, CO2 emissions have been increasing rapidly. This shows the need for energy efficient wireless networks or green wireless networks which will put emphasis on saving the energy and environmental protection. The current wireless networks concentrates mainly on non-energy related factors such as Quality of Service (QoS), throughput and reliability. So these factors have to kept in mind while transitioning to green wireless networks. The techniques that need to be implemented are aimed at improving energy efficiency but not compromising the QoS, throughput and reliability.   In this paper the various metrics which help in evaluating performance of wireless networks are reviewed. Also different approaches to improve energy efficiency in wireless networks an d how to combine them for higher energy efficiency are discussed. Introduction: The latest mobile phones provide multiple services which led to rise of ICT traffic. ICT constitutes for 2% of total Green House Gas (GHG) and CO2 emissions worldwide. Within the ICT sector, mobile sector was responsible for 43% of emissions until 2002 while studies suggest that this number would go up to 51% by 2020 [1]. The predominant energy consuming part in a wireless network is the Radio Access Network (RAN). This comes from the fact the RF power amplifier within the RAN consumes a lot of input power for operation and releases a lot of heat contributing to energy wastage. In addition to this, the inconsistent distribution of real world mobile traffic among the BSs leads to underutilization of supplied energy [1]. These two reasons give us an idea of where the energy is being wasted or not utilized, helping us in formulating new techniques for energy efficient wireless networks. While discussing about various techniques for energy efficiency, we have to keep in mind that the QoS is not compromised at all. Because if an operator uses a technique, they should be able to serve the users by utilizing less energy but not by compromising users service. The various parts of a mobile network that consume power are data centers in backhaul, macro cells, femtocells, mobile stations or end hosts and their services. But the major part that consumes the highest power is the power amplifier section and Base station or RAN section. Hence the various techniques presented in this paper are aimed at energy efficiency in these sections only. Section II of the paper outlines various metrics which can be used to evaluate the energy performance of systems. Section III discusses cell layout adaptation techniques for reducing energy consumption and is divided into 3-subsections that outline various cell shaping algorithms. Section IV explains some challenges and research directions for energy efficient networks like Cognitive Radio (CR), M2M communication etc. Metrics for measuring energy performance: Energy efficiency can be achieved by employing better techniques. But in order to measure the energy consumption or utilization, metrics are needed. Energy efficiency metric can be defined as ratio of output to the input power supplied [1]. The output here may correspond to how much the distance of transmission is, number of bits transmitted or output power etc. The metrics for energy efficiency are broadly categorized into 3 levels: Component level metrics, Access node level metrics and network level metrics. Component level metrics mainly focus on power amplifier section, Access node level metrics focus on RAN or Base station, and network level metrics focus on performance of RAN [1]. These metrics help to quantify energy efficiency of various devices and therefore it becomes easier to compare which technique is better. Firstly, at the component level, where we focus on power amplifier section, there are 2 possible types of metric categories. One is Analog and the other is digital. The two important metrics of analog RF transmission are Power Amplifier efficiency (PA efficiency) and Peak to average power ratio (PAPR). PA efficiency is the ratio of PA output power to the input power supplied to it. Higher value of PA efficiency is desired, but in reality this is the part where most of the input power is wasted. PAPR, as the name suggests is the ratio of Peak power to average power. Lower value of PAPR is desired, as higher values tend to reduce the amplifier efficiency. The significant digital metrics in component level are millions of instructions per second per watt (MIPS/W) and millions of floating point operations per second per watt (MFLOPS/W). Higher value of MIPS/W and MFLOPS/W are desired as they refer to digital output generated for a given power input [1]. Secondly, at access node level there are 2 major metrics. Power efficiency and radio efficiency. Power efficiency refers to transmitted data rate over a given bandwidth and input power supplied. It is measured in bits per second per hertz per watt (b/S/Hz/W). Radio efficiency refers to transmitted data rate and transmitted distance over a given bandwidth and input power supplied. It is measured in bits meters per second per hertz per watt (b-m/S/Hz/W) [1]. Higher values of power and radio efficiency are desired as they measure the data rate and distance of transmission which are always desired to be a higher value for a given power input. Finally, at the network level also there are 2 metrics which measure the number of subscribers served during peak hours and coverage area respectively. The first metric measures the number of subscribers served during peak hour to the supplied input power and is measured in number of subscribers per watt (Subscribers/W) and the second metric measures the coverage area of the radio signal to the supplied input power and is measured in square meters per watt (m2/W) [1]. Higher values for both these metrics are desired as they signify serving more number of subscribers or a larger coverage area for a given power input. Hence when evaluating various techniques for wireless energy efficiency, it is better to know at whether energy efficiency is augmented in component level or access node level or network level. That way it would become easier to compare the efficiency in terms of various levels individual metrics. Reducing Energy consumption through Cell Layout Adaptation: Cell layout adaptation (CLA) techniques focus on energy efficiency at network level. But for these techniques to improve energy efficiency, it is important to improve efficiency in component level and access node level as well, because all these 3 levels are inter-related to each other and one works on the basis of another. Power is first supplied from power amplifier and then to RAN and at last to the network level, that means it is possible to save more energy in component level and access node level and the remaining energy that is used by the network can be efficiently utilized by implementing these cell layout adaptation techniques. CLA techniques are basically divided into 3 major categories. First part consists of cell shaping techniques like Base Stations (BSs) turning off and cell breathing, second part consists of hybrid macro femtocell deployments and the final part consists of relaying techniques [1]. A. Cell Shaping Techniques: As mentioned earlier, base stations turning off and cell breathing techniques encompass cell shaping techniques. The basic idea behind the former is turning off BSs and redistributing the remaining traffic to neighboring base stations. Here we need to make sure that we are turning off BSs which are idle or the ones which have very less traffic that can be taken up by neighboring cells. This way energy consumption is reduced and only the BSs that have traffic will operate and consume energy. Cell breathing scheme goes one step further by not actually turning off BSs, but by reducing the power consumption of a cell. This can be achieved by covering a low distance depending on the traffic. That means BSs experiencing higher traffic operate in full power mode while the BSs with medium traffic operate in medium power mode and cells with very less traffic operate at low power mode, thereby reducing the coverage area depending on subscriber traffic. This is analogous to a cell breathing acc ording to traffic patterns. As these cell shaping techniques are based on network level, number of subscribers served and coverage area metrics should be maintained in order to ensure good QoS and less call drop rate when implementing these techniques. The broader explanation of cell shaping techniques is mentioned above, but to implement those techniques there are 2 major algorithms: switching-off network planning algorithm and cell breathing coordination algorithm [1]. Firstly, switching-off network planning algorithm works on the basis of 3 factors, number of BSs to turn off, number of BSs to operate, and time period for which BSs are turned off. The ratio of number of BSs to turn off and BSs to operate and a specific time period for which turn-off is implemented based on the low traffic pattern is calculated. Once these values are calculated, it is made sure that the blocking probability limit is not exceeded, which means definite QoS is maintained. Cell breathing coordination algorithm works on the basis of a central node called a cell zooming server. The cell zooming server analyzes the incoming traffic and tries to turn of the BSs which do not have any traffic at all. Then it tries to distribute the traffic from less active BSs to busy BSs. It also makes sure to distribute traffic based on input traffic and turns on the sleep mode BSs when required. This centralized approach works good in smaller networks and when it comes to large scale networks, it would be very ineffective. The same applies to switching off network planning algorithm because there is no centralized node to turn on the BSs if needed, as the turn -off time if fixed based on traffic patterns [1]. The cell shaping techniques also bring up a new trade-off, i.e. SE-EE tradeoff (spectral efficiency-energy efficiency) [3]. SE-EE trade-off focuses on network level characteristics like number of subscribers served and coverage area for input power supplied. By implementing these cell shaping techniques although energy efficiency is obtained, there is always chance where coverage area is reduced and some subscribers are ignored. Ideally, higher the energy efficiency lower is the spectral efficiency. But in reality, because of component level energy issues, transmission distances, coding schemes the relationship between SE and EE is not inversely proportional, but it is of the form of a bell curve. So it is better to apply cell shaping techniques until the point where spectral efficiency is not compromised. B. Hybrid macro femtocell deployment: Femtocell deployment in combination with macro cells is a second method under cell layout adaptation. Femtocell deployments provide coverage in the order of 10 meters and utilize a small BS, which requires less power to operate. Femtocell deployment is advantageous as it provides good coverage and QoS to a set of users within its range with less operating expenses when compared to a macro BS [1]. Although femtocell deployment is a good concept, it is not desirable to have too many femtocells as it increases the power consumption and utilizes more network resources for a lesser coverage area. A better way of deployment is having hybrid macro and femtocell deployment. In the case of hybrid deployment, the macro BS provides coverage to users who are evenly spread over a long distance and the femtocell provides coverage to users who are located in a dense region. This way the energy is utilized efficiently, as a new macro BS is not being deployed to provide coverage to those dense set of users. The hybrid macro cell and -femtocell deployment poses a new challenge for handoffs, as macro BS and femtocell BS might have same signal strength in the others coverage region. The handoffs issue can be solved by defining a clear boundary between the macro and femtocell BS. Within the dense region, the femtocell should have higher signal strength and it should properly handoff at the bounda ry of macro BS. Also within the coverage area of macro BS, the femtocell BS should have very less signal strength [1]. This would give a clear idea to define a boundary. A better way of implementing this hybrid deployment is by utilizing the cell shaping techniques like BS turning off and cell breathing coordination. If there are a set of femtocells, and one of the coverage area is totally idle, then that femtocell BS can be turned off and basic coverage is provided by the macro BS at that location. Similarly, if incoming traffic is analyzed, femtocells and macro cells can use the cell breathing techniques to lower their power utilization [1]. Also the hybrid macro and femtocell deployment leads to a DE-EE tradeoff (deployment efficiency-energy efficiency) [3]. Ideally energy efficiency increases when more femtocells are deployed and deployment efficiency goes down because of increase in deployment expenses, network utilization and energy consumption. In a practical scenario, the relationship between DE and EE is more like a bell curve, with a peak point where deployment and energy efficiency are in good standing. Hence it is a good idea to use hybrid deployment until the point where it does not degrade the deployment efficiency and energy efficiency. C. Relaying techniques: Energy efficiency can be achieved through 2 types of relaying techniques. The first technique uses repeater stations or green antennas for relaying and the second technique uses mobile stations for relaying. In the first technique, a repeater station or a green antenna with receiver capability is connected to the macro BS through a coax cable or optical fiber, with the latter utilizing less energy. These green antennas are placed very near to the mobile stations, which helps to reduce the energy consumption in uplink by the mobile stations. Although this technique improves energy efficiency for mobile stations, it increases operating expenses for the service provider. In the second technique, the mobile stations work in coordination and perform the relaying operation. This way the transmission distance for the macro BS is reduced and it consumes less energy. Although this technique assumes mobile stations as relays which work selflessly. Practically, the mobile stations may not work in coordination which would break the link for relaying. One more drawback of this technique is that for maintaining coordination between the mobile stations, more energy is consumed [1]. Challenges and directions for energy efficient wireless networks: Cognitive Radio (CR) and M2M (Machine to Machine) communication systems provide new opportunities in the field of green wireless networks, but also pose significant challenges at the same time. Cognitive Radio can be defined as a RF transceiver that is used to switch users from a very busy spectrum to an unused one and vice versa if needed. The origin for this topic came from the fact that many RF spectrums are congested with several users and some other spectrums are underutilized. Hence the concept of CR would efficiently manage users in various spectrums and help to deliver better QoS. Indirectly this switching of spectrums or utilizing unused spectrums is resulting in energy efficiency as spectrums with more users will not utilize additional energy as users are transferred to other spectrum. Also underutilized spectrums which were consuming energy for operation, now serve the new users efficiently resulting in energy and spectrum utilization. The only disadvantage of CR technique is that monitoring various RF spectrums and switching users from one spectrum to another requires significant energy. Hence this technique would be energy efficient only if more energy is saved by intelligently switching users than that is utilized for monitoring spectrums or users [2]. M2M wireless communication systems are aimed at connecting various wireless devices directly. This approach also helps in reducing energy consumption from the point of view of a mobile station. M2M helps to reduce the computation required by various physical devices and also tries to offload them to the network itself. This way the mobile stations consume less energy as the number of computations is reduced. The major disadvantage with this approach is that if more computation is offloaded to the main network, it might consume more energy that that is being saved by mobile stations by utilizing this approach. Hence this technique would be energy efficient if the main network does not consume a lot of energy for some additional computations [2]. Conclusion and Future Scope: The rise in carbon footprint, especially the contribution to it from the ICT sector and consequently mobile sector led to interest in energy efficient wireless networks. Energy efficiency can be achieved at various levels such as power amplifier, RAN and network. The techniques proposed in the paper focus on energy efficiency in RAN and network levels. But they also have trade-offs like DE-EE and SE-EE, which can be vanquished by emerging techniques like CR and M2M communications. These emerging techniques can be improved in a way where they consume less energy for monitoring in comparison with the prevailing levels. Alongside that, at the power amplifier level, the current solution for energy efficiency is to use expensive components which would trade off the gains achieved by energy savings. Hence a future research direction would be addressing energy efficiency at power amplifier level and improving CR and M2M techniques. VI.

Hey Gaby, I just started my class online with the University of Phoenix, let me tell you a little bit about it because I know you were interested in going back to school as well. Online courses are also known as distance learning, which means that you are earning your education via online. Instead of being in a traditional classroom setting and having that face to face contact with your teacher, distance learning is student centered instructional format that allows you to take courses without having to commit to a regular campus attendance. I personally enjoy doing distance learning; so far I have been able to easily concentrate on my work. The reason why I chose to do distance learning is because I really have a hard time attending regular face to face classes due to my work schedule, very much similar to the situation you are in Gaby. Just like your goals I want to continue to pursue my degree further and I didn’t want to stop attending school so I chose this avenue. Distance learning is a field where instructional systems are designed to deliver education to students who are not able to physically be in classroom site. In my opinion I think you would enjoy distance learning and you would be able to focus a lot easier. I really enjoy doing it because I love working with computers, some people say that they do not like it but most people that I have spoken to say that they really enjoy it as well. You should really try it I truly recommend it; I was scared at first because I was concerned about having questions that I would like to ask my teacher in person and via online you do not have that opportunity. The method used to communicate with your professor and or classmates is through forums and thread discussions. In these forums and threads you post your questions and responses to other posts as well, somewhat like a live chat room. This is referred to as asynchronous communication; because you are not receiving feedback onsite like you would in a regular face to face classroom. To be honest with you it was a little frustrating learning how to navigate thru everything but once I had spoken to my advisors and they explained to me how everything worked things went so much smoother. As the time has gone by I have gotten the hang of it and I think you would pick up the process pretty easily too. Hope that this information has shown you that there is a way for you to continue your education just like I am.

Kenya DBQ Essay

Colonialism occurs when one nation takes control of another. And that is exactly what happened when the British arrived in Africa. The people of Africa had no idea that the British was taking and had taken their land. But, with that being said the British are who had help develop Kenya by bringing them some of their viewpoints from Great Britain. These viewpoints did a number of things to the people Africa. They changed the way they were politically, economically, and even culturally (religiously). The culture or religion of Africa was a very diverse. They all had their own beliefs and myths about how the creation of everything came to be such as the Abaluyia creation story, where it says that god created man so that the sun would have someone to shine on (Doc 7). The British did not really understand this, given the majority of them were either Protestant or Catholic. They couldn’t comprehend the idea of believing in witchcraft or witch doctors, or how each tribe had a concep t of a â€Å"Supreme Being† (Doc 6). But, as more years went by the number of people believing in indigenous beliefs went down. 38% of the people in Kenya were Protestant and 28% of people became Catholic, while from the original 80% of people who followed indigenous beliefs, only 8% of the people stuck to those beliefs (Doc 8). The economical impact that the British had on Africa was one of the few things that actually benefited them. The education of Africans was provided, even though it was not compulsory, with 3,442 schools (Doc 10). In total, there were 395,000 students that attended these schools (doc 10). And within 50 years there was a substantial amount of growth in both Railroad and Road networks throughout Kenya (Doc 11). The cause for the majority of economically growth came from all the raw materials and cash crops that were being sold and produced for Britain. Politically, there were differences amongst both the people of Kenya and the people of Great Britain. When the British came and announced that the people of Africa now had a new king to serve under and that their land was his, the people were confused (Doc 3). The people could not understand how this foreign king was now their king and how the land that was passed down from their fathers’ father, now belonged to this stranger of a king (Doc 3).

Water and sustainability Essay Example | Topics and Well Written Essays - 1250 words

Water and sustainability - Essay Example conomy and population over the past decades has brought tremendous cost to the nation’s environmental sustainability (Liu, Jianguo, and Wu Yang 650). Although both China and the USA are economically developed, the simultaneous effects of the industrialization, agricultural growth, and urbanization coupled with the declining ground and surface water quantity are some of the crucial problems facing water sustainability in China. This paper therefore, explores the comparison of water sustainability between China and USA while taking keen interest on the problems of the water sustainability in China and the solutions. The USA’S EPA (Environmental Protection Agency) is committed to the promotion of the sustainable practices that helps ensuring that the citizens continue enjoying the benefits of the safe and clean water. As a result the tap water in the USA relatively cleaner as compared to that of China. The tap water in U.S is generally good.

Unlike China, most of the water systems in the USA that are out of compliance are the small systems in the small towns and rural areas partly because most of the public water systems are generally small ones. Another reason for the cleaner tap water in the USA is that the drinking water in the U.S is regulated by the federal and state laws and codes that sets Maximum Contaminant Levels for some of the pollutants and the naturally occurring constituents. The federal and state laws and codes are tasked with the determination of the various operational req uirements, public notifications of the standards, provision of guidance to the state primacy agencies and publish the consumer confidence reports (Liu, Jianguo, and Wu Yang 650).

This is when peer influence is highest and many women try to fit in the society ending up getting pregnant and seeking abortion1. Abortion was legalized in America in 1973 by the Supreme Court. However, it became a very controversial issue. This is mainly because of the different ways that people look at abortion. Many are influenced by their religious beliefs, public health issues and ethics. Others believe that one should not suffer because of a pregnancy they had not even planned for in the first place. Before contraceptives became popular, may women in the United States had unplanned pregnancy. This was especially for young mothers who could not space out their children and thus had many maternal health problems. Later on, in the late twentieth century, the use of contraceptives reduces significantly, as the family planning methods became popular2. However, lately, due to politics interfering negatively with the use of contraceptives, unplanned pregnancies have drastically augmented. This is because the negative views of some politicians made some stakeholders to withdraw their financial support for family planning companies. In the recent past, the American lawmakers who belonged to the Republican Party were against abortions. Therefore, in the sittings that happened in 2011, they tried to make sure that the cost of having an abortion was very costly for women.
