Opening Paragraphs of the I Have a Dream Speech by Martin Luther King, Jr. Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation. This momentous1 decree came as a great beacon light of hope to millions of Negro slaves who had been seared2 in the flames of withering3 injustice. It came as a joyous daybreak to end the long night of their captivity. But one hundred years later, the Negro still is not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles4 of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languishing5 in the corners of American society and finds himself an exile in his own land. And so weve come here today to dramatize a shameful condition. In a sense, weve come to our nations capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note6 to which every American was to fall heir. This note was a promise that all men, yes, black men as well as white men, would be guaranteed the unalienable Rights of Life, Liberty and the pursuit of Happiness. It is obvious today that America has defaulted7 on this promissory note, insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked insufficient funds. But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. And so, weve come to cash this check, a check that will give us upon demand the riches of freedom and the security of justice. We have also come to this hallowed8 spot to remind America of the fierce urgency of now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism9. Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate10 valley of segregation to the sunlit path of racial justice. Now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood. Now is the time to make justice a reality for all of Gods children. momentous(a) lasting for just a brief moment(b) of great importance or significance(c) belonging to the distant pastseared(a) painfully burned or scorched(b) highlighted, illuminated(c) lost, forgotten, abandonedwithering(a) devastating, humiliating(b) refreshing, rejuvenating(c) non-stop, endlessmanacles(a) laws, rules, principles(b) habits, routines(c) shackles, handcuffslanguishing(a) hiding, kept out of sight(b) existing in miserable or disheartening conditions(c) lasting for a long time or slow to endpromissory note(a) a written promise to repay a debt(b) a union formed for mutual benefit(c) a pledge to do what is right under the lawdefaulted(a) brought shame or disgrace on someone(b) rewarded or paid back(c) failed to fulfill an obligationhallowed(a) formed by making a hole(b) nearly forgotten, largely ignored(c) highly respected, regarded as holygradualism(a) forcible overthrow of a social order(b) a policy of step-by-step reform over time(c) forgetfulness, neglectdesolate(a) brightened with light(b) depressingly empty or bare(c) profound, deep Here are the answers to the Vocabulary Quiz on the I Have a Dream Speech by Martin Luther King, Jr. (b) of great importance or significance(a) painfully burned or scorched(a) devastating, humiliating(c) shackles, handcuffs(b) existing in miserable or disheartening conditions(a) a written promise to repay a debt(c) failed to fulfill an obligation(c) highly respected, regarded as holy(b) a policy of step-by-step reform over time(b) depressingly empty or bare

Slavery And The United States - 1507 Words

Over the centuries, slavery held a prominent factor in United States history. Slavery shaped and formed what society was in the United States. Slavery’s influence impacted the United States in various ways. The ways that slavery impacted United States history are the United States economy, society and politics. Some historians argue slavery is not an important factor in United States history. However, they are wrong because slavery brought many different political movements and the Underground Railroad marked it’s importance in United States history. Slavery had an economic impact in the United States. In 1794, an inventor named Eli Whitney created the cotton gin. The cotton gin revolutionized the South’s economy. Upon the creation of the†¦show more content†¦Instead of big cities and industrialization in the North, the South had large plantations and fields. Slavery was important to the South’s economy because they have a long growing season and a warm climate for farming. When the region has a great climate for farming, why would the South change their economy? Slavery greatly influenced the United States economy by dramatically increasing the production of crops such as cotton and provided large amounts of labor to upkeep with production of the crops. Slavery had a social impact in United States history. During the colonial era and antebellum era in the United States, slaves were not treated with respect. In the documentary â€Å"Slavery And The Making Of America†, there were ways and methods of who slaves were treated. For instance, when slaves ran away for the first time, they get whipped. For the second time, the runaway gets an â€Å"R† branded on his right cheek. The third time, the slave has their ear severed and another â€Å"R† is branded on the left cheek, and for the fourth time if the slave is a male, he gets castrated. When white men did the same crimes, they served short terms in jail or lesser punishments for crimes. African Americans were judged very harshly during this point in United States history. White Americans believe they had superiority over the African American slaves because of their skin color. Edward Bull, author of â€Å"Slaves in the Family†, spoke in the documentaryâ€Å" Slavery And

Explain how the actor viola should show her reactions and give reasons for your suggestions Free Essays

Viola is one of the main characters in Shakespeare’s play the ‘Twelfth Night’. She is dressed as Cesario a man, so you can see how hard it must be for her to show her emotions and reactions. In the play she falls in love with the Duke Orsino but finds it very hard to show her feelings for him because she is dressed as a man. We will write a custom essay sample on Explain how the actor viola should show her reactions and give reasons for your suggestions or any similar topic only for you Order Now I am using act 2 scene 4 and act 3 scene 1, where she is talking to the Duke in act 2 scene 4, and to the clown Feste in act 3 scene 1. These are very emotional scenes where Viola shows and mentions her feelings, thoughts, reactions and movement. In these scenes Viola has many feelings. She feels mostly for Orsino because she is in love him. At the end of the scene where she is speaking with Orsino she talks about her fathers daughter that loved a man. Orsino gets interested because he is in love with Olivia but Olivia does not love him. Orsino wants to know what happened to the daughter because he is in despair. Viola feels for him and can offer him no comfort. Her words display how helpless she feels. â€Å"I am the daughters of my father’s house, and all the brothers too-and yet I know not†. Earlier on in the scene Viola feels jealous about Orsino because she feels that he might fall in love with another woman and that he will love that woman as much as he loves Olivia then Viola would never get a chance with him. â€Å"Say that some lady, as perhaps there is, hath for your love as great a pang of heart as you have for Olivia†. Viola’s thoughts are like her feelings but not mentioned. She finds it very difficult because she is dressed as man and does not want to give her identity away. When she is talking with Feste the clown, he is acting silly and plays around with words. She says that she is sick for a beard but she turns aside and gives a hint that she is a woman. She says that she would not have it grow on her chin, because she is a lady. â€Å"I am almost sick for one; (aside) though I would not have it grow on my chin. Is thy lady within?† When she is talking with the clown she thinks that he cares for nothing because he plays around with words and she is quite angry with him. Viola is saying her thoughts out to the clown because she does not like him. â€Å"I warrant thou art a merry fellow and carest for nothing†. Viola reacts to some things that the Duke says. She loves the Duke so she reacts to him in a kind way as not to make him angry or hurt his feelings. In act 2 scene 4 Viola says to the Duke that Olivia cannot love him but the Duke acts stubborn and says that he cannot be so answered. Viola reacts and tells him to calm down but she means not to be hurtful because she loves him. She tries to relax him and tells him to calm down. â€Å"Sooth, but you must†. There is very little of Viola’s movement. I would say that Viola moved around with Feste the clown because the clown was getting on her nerves. It was in act 3 scene 1 where near the end of the conversation with Feste Viola gives Feste a coin. She moves a round a lot to get away from him because he is pestering her and she wants to get away. She gives the coin to Feste so he can go away. â€Å"I’ll no more with thee. Hold, there’s expenses for thee†. I think that Shakespeare’s language is very difficult to understand. There are mixed emotions in the play because Viola is dressed as a man but some of it was quite obvious to understand. Overall I thought the way Shakespeare set this play out was very well and I thought the scenes were well organised.

Headspace System Design Project for Storage - myassignmenthelp

Question: Discuss about theHeadspace System Design Project for Storage. Answer: Introduction Cloud computing has in the past few years revolutionized the methods of accessing IT resources through the leasing services it offers to end users. This outcome has increased the benefits of virtualization where today many organizations are shifting their resource requirements online owing to the increased accessibility and availability benefits. Moreover, cloud computing adequately minimizes the cost of operation because the resources are implemented and maintained by service providers while they (the end users) apply them. Therefore, in cases where IT infrastructure such as computing power, storage and networks are needed, the users simply subscribes to service providers while considering their immediate requirements(Huth Cebula, 2011). Similarly, Headspace requires a similar approach to its service systems where a lot of information is needed which increases the resource requirement. Furthermore, the organization requires efficient resources that are readily available to the user s at any given time. Now, this report highlights these feature/requirements and how they can be fulfilled by cloud computing. In addition to this, the different implementation procedures are given based on the non-functional requirements of the proposed system. The systems nonfunctional requirements In comparison with the functional requirements, non-functional requirements highlight the characteristics and attributes of systems that enhance the interactions between the users and the developed platforms. Therefore, they have minimal technical components but will determine the overall rate of system satisfaction. In this case, security and data ownership are critical components which should be reflected in these requirements(Chung, 2012). Lets highlight some of the key components of the non-functional requirements: Performance technically speaking, a multitude of components determine the overall performance of the system. These components should have an adequate interaction to facilitate the actions of the user e.g. compatibility with all operating systems and other computing resources. ii. Usability system practicality, the system should not be simple to use but yet have poor security features. A balance between security, privacy and practicality must be exhibited. iii. Security system authentication and encryption must be incorporated to offer an end to end system protection and encryption, functionalities that will improve the access limitations i.e. data security and ownership(Taylor, 2000). System qualities Now, based on the outline of the non-functional requirements, the system qualities will define the overall attributes that will yield a favourable system for the health department as given by the Headspace project. Therefore, it should be easy to use based on its performance, an outcome that requires the balance between reliability and functionality. In essence, the system technicality must cater for the end user who will have varying literacy levels. Finally, the security should protect the data in use and critically outline the ownership conditions(Gorton, 2011). System and user interface (UI) While there a lot of background services executed by the system, the end user tends to judge systems based on the visual displays i.e. the graphical user interface (GUI). Therefore, the system at hand must exhume the following attributes: Easy accessibility regardless of the platform or network used. Reliability-based on a consistent performance. Pleasing i.e. good aesthetic beauty and representation(Hassan, 2015). Now, to meet these attributes the UI must implement its elements carefully based on the demands of the user. These UI elements include the systems background, icons, colours and fonts. In this case, the design should incorporate versatility and adaptability features as many users are set to use the system, for instance, the background, colours and fonts should be adjustable to meet the users preferences. On the other hand, the icons should be permanent but based on the user specifications. In essence, icons will form a key component of guiding the system usage thus, their location and operation are critical for variation instances(Gorton, 2011). System constraints Two general constraints are set to affect the implementation and usage of the system, they are: Functional restrictions consider the deployment languages and operating systems to be used. The developer will compromise on some functionalities to satisfy the needs of these elements. Business restrictions the budget and most importantly the time of development will never be enough(Dettmer, 2006). Cloud-based solutions Cloud resources and services have existed for a very long time, from online mailing service (E-mails) to document storage facilities as supported by the various search engine providers. In essence, although they were never deliberately outlined as cloud resources, their deployment structure is the basic definition of cloud computing. The same outcome is also exhibited by organizations who share resources among many employees through a centralized server(models, 2016). In all, cloud-based solutions are designated by leased resources given to a user or organization from a third party member. Therefore, the common notion of there is no cloud but someone elses computer is born. Now, the Headspace project is in great need for this technology owing to the resources it requires to serve its patients. For one, very many patients are attended to by this organization which increases the size of the storage facilities needed. Secondly, the data from the patients must be readily available to all practitioners in order to improve the effectiveness of the treatments. Finally, these resources must also adapt to the changes of the organization which include changes in personnel, data storage and user location(service, 2017). Cloud-based solutions are online facilities that deliver IT resource to users based on their demands. This outcome enables a service delivery system that uses a pay per use model. This model would adequately serve Headspace as their resource requirements will vary from time to time. However, at the same time, cloud computing does also present several challenges particularly those of security and privacy(Primault, 2016). Advantages of cloud-based solutions Resource flexibility and mobility patients during their treatment may see a general health worker, medical practitioner and a psychologist. This outcome will require a mobile infrastructure to enable the accessibility of resources at all time. Cloud resources are online systems that can be accessed at all time and in any given location. Cost effective the storage, network and processing power is provided by the service provider, a cost reduction for the user. Future advancement cloud computing encourages innovation and technological advancements(Alton, 2015). Disadvantages Data security and privacy data is stored in unknown locations and using unknown techniques. Moreover, its difficult for users to track their resource which increases the security threats. Loss of system control no physical manipulation of resources can be done and including the tagging of general data traffic(Bauerle, 2014). Software development lifecycle (SDLC) After considering the requirements of the system including its access and hosting in cloud facilities, its design is the next logical step. Now, there is a multitude of factors to consider, from time to user preferences. Therefore, a project like procedure should be used to implement the project having identified the requirements of the users. SDLC defines this procedure and will provide several logical structures to implement the final solutions. In this case, two approaches are highlighted adaptive and predictive SDLC(architects, 2017). Predictive Approach This approach makes several assumptions in its design process, for one, it assumes that all the parameters of development are known. Furthermore, it assumes that these parameters will remain constant through the implementation process (life cycle). Therefore, a clear-cut procedure is outlined, having all the resources of the system such as personnel, functional and non-functional requirements, and even time. Moreover, the approach also provides a logical guideline of the implementation procedure where each and every step of development is given in a sequential manner. This outcome necessities the need to follow a systematic approach where each design and implementation stage is executed without any form of overlap(Okoli Carillo, 2010). Now, unlike other SDLC methods, the violation of these terms (sequence and changes) result in complete do-overs of projects as the system structure is violated. Pros of the approach Its a simple approach because all the steps are usually clearly outlined. Secondly, it requires minimal resources as they are budgeted for before the implementation process. Furthermore, its an accountable approach as comparisons can be made using the systemic procedures. Cons Rigid and lacks any form of flexibility. Time intensive as all steps must be followed sequential without overlap(Okoli Carillo, 2010). Adaptive approach A complete opposite of the predictive approach where the conventional model of system development is completely avoided. In essence, the adaptive approach will live up to its name by employing agile procedures in system development. Therefore, the procedures used will adapt to change and even give room for any system variations. Furthermore, the approach will split the implementation process into several stages which can be executed simultaneously thus minimize the time of development. After dividing the stages of development, the approach will then use several assembly techniques to deploy the final solution. Now, iteration methods are commonly used for this step, where several recurring assembly steps are executed to perfect the final solution. In all, the final system is usually as a result of several prototyping instances(MIS, 2015). Pros of adaptive SDLC A flexible approach that adapts to any changes and variations. Time efficient as several implementation stages can be executed at once. Thirdly, produces better systems as the design is based on the users needs as reflected on the prototypes. Cons Adaptive SDLC method is resource intensive, from expenditures to expertise requirement. It is also difficult to estimate timelines as the system continuously adapts to the existing conditions(Okoli Carillo, 2010). The recommendation First, predictive SDLC approach highlights the traditional or conventional method of implementing systems. Therefore, while it may hold several benefits including design accountability, its feature limits the development processes of modern systems that are agile and versatile. On the other hand, adaptive SDLC approach is the haven for modern systems, incorporating conveniences such as flexibility, mobility and scalability. Therefore, in case the Headspace project requires a change in personnel, the design is able to adapt(architects, 2017). Moreover, the approach drastically minimizes the development time, a key component of any system today more so, those used in service delivery. For these reasons, the adaptive approach is the best method for designing and implementing the Headspace project. Conclusion This report has given the various considerations for implementing the Headspace project. In essence, an analysis of cloud computing and its integration into a modern system have been given where its agility and flexibility have been highlighted as a key component of the systems requirements. Moreover, the non-functional requirements which basically outline the systems interaction with the user have outlined the importance of secure facilities as supported by clear data ownership guidelines. Finally, the report has also given a detailed comparison between the predictive and adaptive SDLC approach methods, where the adaptive approach has been chosen owing to its benefits which are majorly favoured by its agility features.

Shakespeares Comedy Vs. Tragedy Essays - Fiction, Literature

Shakespeare's Comedy vs. Tragedy Certain parallels can be drawn between William Shakespeare's plays, "A Midsummer Night's Dream", and "Romeo and Juliet". These parallels concern themes and prototypical Shakespearian character types. Both plays have a distinct pair of ?lovers', Hermia and Lysander, and Romeo and Juliet, respectively. Both plays could have also easily been tragedy or comedy with a few simple changes. A tragic play is a play in which one or more characters is has a moral flaw that leads to his/her downfall. A comedic play has at least one humorous character, and a successful or happy ending. Comparing these two plays is useful to find how Shakespeare uses similar character types in a variety of plays, and the versatility of the themes which he uses. In "Romeo and Juliet", Juliet is young, "not yet fourteen", and she is beautiful, and Romeo's reaction after he sees her is, "O, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night As a rich jewel in an Ethiop's ear Beauty to rich for use, for the earth too dear!" Juliet is also prudent, "Although I joy in thee, I have no joy in this contract tonight. It is too rash, too unadvised, too sudden." She feels that because they have just met, they should abstain from sexual intercourse. Hermia is also young, and prudent. When Lysander suggests that "One turf shall serve as a pillow for both of us, One heart, one bed, two bosoms, and one troth," Hermia replies "Nay, good Lysander. For my sake, my dear, Lie further off yet; do not lie so near." Although this couple has known each other for a while (Romeo and Juliet knew each other for one night when the above quote was spoken), Hermia also abstains from even sleeping near Lysander even though she believes he does not have impure intentions. Romeo's and Juliet's families are feuding. Because of these feuds, their own parents will not allow the lovers to see each other. In the a differnet way Hermia is not allowed to marry Lysander. Hermia's father Egeus says to Theseus, Duke of Athens, "Full of vexation come I, with complaint Against my child, my daughter Hermia. Stand fourth, Demetrius. My noble lord, This man hath my consent to marry her. Stand forth, Lysander. And, my gracious Duke, This man hath bewitched the bosom of my child." Egeus tells the Duke that his daughter can marry Demetrius, not Lysander. Hermia replies ". . . If I refuse to wed Demetrius," Egeus replies "Either to die the death, or to abjure for ever the society of men." If Hermia does go against her father's wishes, and weds Lysander, she will either be put to death, or be forced to become a nun. Both pairs of lovers also seek help from another. Juliet and Romeo seek Friar Lawrence, and Lysander and Hermia seek Lysander's aunt, who lives in the woods near Athens. Both sets of youths have the same character type. They are young, their love is prohibited, both women are prudent, and both seek the help of an adult. Yet they have their subtle differences. For example, Lysander, never mentioned a love before Hermia. Romeo loved Rosaline, before he loved Juliet. Hermia's family and Lysander's family were not feuding, whereas the Montagues' and Capulets' feude was central to the plot of the play. The stories of "Romeo and Juliet" and "A Midsummer Night's Dream" are very different however. "A Midsummer Night's Dream" is a comedy. Oberon, king of the fairies, sends a mischievous imp named, Puck, to play a trick on the queen of the fairies, Titania, and on a pair of Athenian youth. Puck turns Nick Bottom's head into that of an ass (Nick Bottom is the man in the play production within "A Midsummer Night's Dream"; he tried to play every part), and places an herb on Titania that causes her to fall in love with him. This is quite humorous. However, at the end of the play all the couples are back together, with the ones they love. Thus Lysander and Hermia do get married. If Egeus had showed up at the wedding, he could have killed

The Global Feedbacks of Greenhouse

The Global Feedbacks of Greenhouse Introduction The greenhouse effect entails conditions that allow short wavelengths from sunlight to be absorbed through transparent media. However, these media cannot permit the passage of long wavelengths that are re-radiated from animated substances. Therefore, high temperatures that occur due to overheating are usually experienced.Advertising We will write a custom essay sample on The Global Feedbacks of Greenhouse specifically for you for only $16.05 $11/page Learn More This arises because the long wavelengths are tapped and thus causing variations in the atmosphere. It is a major issue in the world today since climatic changes cause precipitation and global warming. The accumulations of anthropogenic supporters and induced greenhouse gases encourage temperature variations. However, the greenhouse gases are transparent to the inflowing solar radiations. These gases include CFCs (chlorofluorocarbons), O3 (troposphere ozone), N2O (nitrous oxide), CH4 (meth ane), CO2 (carbon dioxide), and water vapor. The gases attract and change the inward radiations to long wavelength. Hence, they cause thermal energy. Besides, some activities carried out by man tend to increase the amount of gases retained in the atmosphere. This causes the greenhouse effect (Emanuel 2320). This study investigates the greenhouse effect. It also looks at the increase in trace-gases concentration, and the global feedbacks of greenhouse. Views on the greenhouse effect A greenhouse is a phrase that scientists originally used in the fiscal 1980s. It was used to explain the purpose of trace-gases that naturally occurred. This hardly imposed pessimistic implications on the atmosphere. However, the atmospheric scientists saw that the greenhouse effect was attached to most climatic change anxieties. Recently, negative expressions have taken center stage as to what constitutes the greenhouse effect (Lindzen 8339). These concerns are connected to the probable impact of the gre enhouse effects. Therefore, research shows that life would not have been possible without the greenhouse effects. In fact, the temperature of the earth is dependent on the atmospheric actions of the greenhouse effects. Several factors affect greenhouses. This is because of its effects in cooling and heating the atmosphere. An essential facet of the atmospheric orangery is the nature of plane that is initially hit by rays. The surfaces such as cities, deserts, ice caps, ocean surfaces, grasslands, and forests, tend to absorb, reflect, and emit radiations in different ways.Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More A white glacier tends to reflect back sunlight that is falling on its surface. This leads to low atmospheric conditions that accrue from some amount of heat. In contrast, dark desert soils have the capacity to absorb sunlight (Arrhenius 239). This contributes to t he maximum heating of surfaces and lowers the atmospheric temperature. Moreover, the cloud coverage affects the greenhouse warming. It decreases the quantity of solar radiation that is getting into the ground. It also minimizes the degree of energy and waves that are discharged into the atmosphere. Thus, scientists have characterized a fraction of astrophysical vigor that is reproduced by such reflective planes (Reiter 54). This has helped scholars and other people to comprehend the global, regional, and local percentages. The greenhouse effect has therefore helped in the prediction of climatic changes around the world. The greenhouse effect and increase in trace-gases concentration Temperatures of surfaces and those of the atmosphere respond quickly to variations in the absorption of greenhouse gases. Increase in the concentration of clouds or greenhouse gases above the normal levels results into variations in altitude (Lindzen 8340). For instance, improved methane concentrations w ill move the altitude upwards. As a result, the temperature of the upper troposphere will change by half due to increase in surface temperature. This is apparent in a humid surface and its deviation from the altitude. Changes in the concentration will help in calculating the surface and atmospheric temperature changes. For example, double concentration of carbon dioxide increases the world average surface temperature by one degree centigrade. Furthermore, climate systems and mechanisms affect atmospheric greenhouse gas concentration. Plants depend on carbon dioxide for photosynthesis. Hence, they reduce the concentration of gases in the atmosphere (Emanuel 2325). The conservatory absorption in the environment is amplified by individuals’ actions. This is seen in industrial actions that lead to the clearance of forests and smoldering of fossil fuels. Introducing further greenhouse gas in the atmosphere strengthens the greenhouse effect. Greenhouse effect feedbacks Several feed back mechanisms depict the rate at which the globe is warming. Atmospheric warming accrues due the increment in the level of greenhouse gases. The water vapor that is found in the atmosphere also increases. This in turn increases the greenhouse effect. Therefore, excessive global warming is experienced. From such an experience, the vapor found within the reinforcing self-cycle also causes further increment in the greenhouse effect. Due to additional carbon dioxide in the atmosphere, the greenhouse effect can be doubled. Furthermore, clouds constitute an important feedback mechanism. The absorption of infrared radiation by clouds has an impact on the greenhouse that eventually causes global warming (Arrhenius 239).Advertising We will write a custom essay sample on The Global Feedbacks of Greenhouse specifically for you for only $16.05 $11/page Learn More Clouds furthermore echo the received planetary rays to generate the chilly upshots on the crusts’ plane. Therefore, the extent at which clouds cool or warm the earth depends on the changes in clouds, life span, shape, particle size, altitude, water content, position and nature (Schneider 1). Some changes restrain the global warming while others intensify it. Researches on the feedback mechanisms as regards to global warming are still on track. Conclusion It can be concluded that greenhouse gases work by absorbing the infrared radiation. Hence, some energy is radiated back towards the earth surface. This surface also receives radiation from the clouds and the atmosphere. Studies show that clouds and water vapor are the most important greenhouse components in the atmosphere. Nevertheless, water vapor quickly cycles through space, and its concentration is observed as feedback. The ozone, nitrous oxides, methane, carbon dioxide, and clouds are also important elements in the greenhouse. They increase the global warming and its absorption of various gases provided there are excessive concentrations.

Homelessness and Health Care - Essay Example The burden imposed by substance abuse and mental illness are well recorded in homeless people. In addition, chronic diseases are common as many homeless persons have peripheral vascular disease, diabetes, renal disease, hypertension, liver disease, and respiratory problems. Skin diseases are also not left out and are extraordinarily frequent leading to costly hospitalization due to cellulitis. Frostbites and hypothermia are feared life hazards in the streets and have been implied as risk factors for the premature demise. Other conditions, such as lice infestations, pellagra, and diphtheria may ultimately lead to endocarditis from the toxins produced by Bartonella Quintana (Badiaga et al., 2008). The persons caring for this cohort of individuals must marry medicine with aspects of public health since HIV/AIDS and Tuberculosis are endemic, communicable diseases outbreaks such as influenza, violence and trauma are somewhat implied in homeless people and infestations common in shelter. C heung and Hwang (2004) investigated on elevated mortality rates in the United States, England, Denmark, and Canada. A peculiar and disturbing observation made was the apparent absence of notable inputs of health insurance on the predisposition of premature mortality. Incredibly, in the US, there remains 40 million plus citizens without a coverage of health insurance. The rest of the countries had had for a long time universal health insurance. Even with the necessity for a universal coverage, the initiative appears to fall short in preventing early deaths in the homeless population (Cheung & Hwang, 2004). Fundamental improvement in health care delivery is crucial to address the existing health care disparities for such population at risk. The health care of homeless families and individuals poses a distressing challenge to our traditional models of health care delivery. The undying urgency of striving daily for warm meals and safe shelter relegates health care to a less-immediate pr iority (Wright & Tompkins, 2006). Injuries fester and common illnesses progress resulting to increased cases of emergency unit visit and acute care hospitalization. Treatment plans that are sensible to those with family and home support are often inapplicable to difficult, impossible to have bed rest, he homeless people; simple changes of dressing, hard to secure medication and properly store them and adherence to therapy especially those that require multiple daily administrations is flattering.
