Sino-US relations Essay Example for Free

Sino-US relations EssayThe improvement in Sino-US relations was the main factor promoting dtente between Russia and America in the geezerhood 1969-75. How far do you agree with this view?The Ping Pong diplomacy of 1971 begun a period of rapprochement in Sino-US relations. The Chinese dimension to Cold contend diplomacy threatened the USSR which feared a military alliance, and the Soviet Union moved to improve relations with the USA, thereby facilitating the process of dtente. However, the fear of nuclear war, the escalating terms of the arms race coupled with the grim economic realities of the 1970s and the American withdraw from Vietnam and were also highly significant in promoting dtente between Russia and America. The Soviet Union viewed the improvement in Sino-American relations as a threat to its national security, she was now confronted on two fronts and fearing military collusion, the Soviet Union want improved relations with the USA. Soviet fears of the yellow peril d ated back to 19th Century and were reignited by the Sino-Soviet split of the 1960s. Climaxing in 1969 when the Peoples Liberation Army ambushed Soviet troops along the Usuri River, who suffered 59 casualties this action was perceived by Russia as evidence that the Chinese had designs on its territory.Furthermore, following Kissingers secret visit to chinaware in July 1971, the previously internationally isolated China, gained international recognition. She was admitted into the UN with a permanent seat on the Security Council in October that year. The result of this triangular diplomacy for the Soviet Union was the relaxation of tensions with the USA through dtente, the USSR believed this would offer the prospect of isolating China from the US and consequently decrease the threat of an coordinated attack.However, election factors also contributed to promoting dtente between Russia and America in the years 1969-75. The fear of nuclear war and the escalating cost of the arms race pu shed the Superpowers into pursuing better relations. By 1969 two sides had achieved relative nuclear parity in weapons and delivery systems, nuclear war would result in Mutually Assured Destruction. The extensive treaty systems both countries held in the third world, could result in small regional conflict developing into full scale nuclear war. Whilst the cost of maintaining this balance of terror came at great economic cost, preventing much needed social reform. In the early 1970s the USA faced double digit inflation and widespread urban rioting in 1968.In contrast, the USSR had failed in its promise to deliver high-quality consumer products and faced falling GNP growth, from 5% in 1966-70 to 3.1% in 1971-75. These factors made it clear to the various(prenominal) powers that improved relations were necessary to prevent nuclear war, agree on arms limitations and improve softwood agreements chair Nixon and his NSC adviser Henry Kissingers in(predicate) form _or_ system of gove rnment of linkage meant the Soviets would recognise both superpowers had mutual interests in the Third World and opened up badly needed US technology and investment to the Soviet economy. Whilst the signing of arms limitation treaties of SALT 1 and the subsequent ABM treaty in 1972 was possibly the high flush of US-Soviet co-operation engendered by Dtente.Furthermore, the wider international situation of war in Vietnam and the situation in Europe precipitated improved Soviet-American relations. In the USA the war-weary public demanded withdraw from Vietnam which in 1968 had cost 16,889 American lives pushing the administration of President Nixon to pursue better relations with Moscow co-operation was vital to achieve a peace colony with Hanoi. This macrocosm achieved through the policy of Linkage which recognised the Soviet sphere of influence.In return, the USSR would support American peace talks with the North Vietnamese. Furthermore, the uneasy territorial settlement of Euro pe created at Yalta in 1945, which had threatened possible US intervention in 1968 during the Czechoslovakian crisis meant US-Soviet co-operation was vital to ensure peace. The Helsinki Agreement of 1975 continued the policy of East-West dialogue over Europe begun by Willy Brandts successful policy of Ostpolitik during the late 1960s. The Soviet controlled Warsaw Pact gained official US recognition of the post-ww2 European borders, whilst the US largely unsuccessfully sought concessions over human rights issues from the USSR, which following the agreement were widely ignored.In conclusion, dtente was the result of a variety of coordination compound factors, driven by a war-weary United States counting the human and economic cost of militaristic confrontation of Communism in Vietnam. The United States under President Nixon recognised more could be achieved through peaceful diplomacy, whilst both Superpowers recognised that dtente offered the opportunity to curtail spiralling defence spending and open up trade links between the nations. The improvement in Sino-US relations added an important Chinese dimension to Cold War diplomacy, but was not the main factor promoting dtente between Russia and America in the years 1969-1975.

Tangibility and intangibility of humanity Essay Example for Free

Tangibility and intangibility of humanity EssayIn my ar bothrk which is done in clay I attempted to portray how amply and low culture can be merged in a sculpture. My intention for this piece was to portray a character normally found in fiction, and attri thoe it with features that express human emotion. Looking at my piece one could easily say that the bust visualized is that of a non-existent creature, such as an noncitizen or a gargoyle. However, in portraying my theme, I intentionally gave the sculpture a downcast expression as seen in the hollow and downturned eyes as well as the bowed position of the bust. Here, I would like to portray the logical argument between the tangibility and intangibility of humanity where the intangibility is represented by the existence of imaginary or self-inflicted states as I would like to portray in the creature and the tangibility which is represented by the human emotions in the piece. In doing this I believe I was able to achieve what Jeff Coons tried to achieve in many of his artistrys where he tries to represent both levels of culture and auberge in a singular artistic production to establish the link between the ideals and ideas.For instance, in his piece Rabbit he is able to express the merging of two diametrically opposed concepts, novelty and value. The mere fact that the artwork is done in metal but is of a common object, an inflatable bunny, makes the artwork representative of two different social spectrums. This is what I wanted to achieve in my artwork. I can say that I was able to achieve this in my piece by taking something out of fantasy and using this to portray the precise real emotions of humanity.The effect is an apparent fusion between the two concepts which all the more makes it interesting. What my artwork represents is not however strange or foreign except for the fact that there are no fantastical creatures in real life. What it is representative of is the very real phenomenon of deriv ation of emotional instability or the lack of it from the existence of unreal of fictional situations. This concept is quite common among people of high society who believe in one thing but portray another.So, in effect the merging of the high and the low of culture could be easily uttered in my artwork as the apparent and the real what can be seen but is not real and what cannot be seen but is real and genuine. This same concept is portrayed by Koon in his artwork of Michael Jackson and his pet monkey this is an illustration of how a piece, while featuring two very famous figures or family names, actually represents two layers of society and even satirizes the contrast between Jackson and the monkey on a more intimate level.In addition to the features of my artwork that I mentioned I would also like to mention the reason why I intentionally gouged out a line that runs from the forehead down to the chin. small-arm this particular feature seems to present the creature as a humano id hybrid between man and ape, which all the more makes it a fusion of two cultures, the line also makes obvious what normally are imaginary lines in anatomy. This makes the piece more verbose in its portrayal of the tangible and the intangible.I utilize these features in my artwork because I consider genuineness in emotion a component of high culture and the concealment of these emotions in fantasy a component of low culture. I am aware though that the piece I did is not as articulate as I expected it to be, but in more ways than one, it expresses what I want to convey to my viewers. Another aspect that I would like viewers to take notice of is the medium and what is portrayed using the medium I portrayed a fantastical creature using a mundane medium making an even stark contrast between the heights of fantasy and the lows of reality.

Bowlbys Theory of Attachment Essay

Bowlbys Theory of Attachment EssayIn the light of changes to the family since 1950 are Bowlbys ideas about finagle for spring chicken small fryren still relevant today?In this paper, Bowlbys theory of attachment and minor care will be outlined along with additions from other theorists such as Rutter and Ainsworth. From this we will see how the evolution of the family unit since the 1950s has been affected by such theories along with welfare policy and social theorists which have influenced family life and shaver care practices in the UK.Bowlby described attachment as the bond that develops between a baby and its primary caregiver. It is characterised by the interaction patterns which develop in order to bring to pass the infants needs and emotional development. Bowlby noted the apparent distress in children separated from their mothers in unusual circumstances e.g. hospitalisation. In studying the more abnormal and twainer situations he attempted to shed light on an understan ding of normal emotional attachment development, and how a disruption could prove damaging to the child emotionally and by to adult maturation.Bowlby suggested that the presence of the mother was just as crucial to the baby as being supplied basic needs such as food. His conclusions take him to postulate that the distress at separation from the mother was universal in babies. Bowlby characterised this distress as following the pattern of infant protest, followed by despair and culmination in eventual detachment. The term separation anxiety was brought about echoing ethological survival techniques in which patterns of actions enable survival of young animals. Such ideas influenced Bowlby in postulating a significant period attachment of one to five years which was imperative historically to biological survival, and if they were not in place then emotional and capable problems would occur in adulthood.This can be seen as a rigid attitude and has played a large part in influencing child care decisions through the establishment of a connection between maternal absence, child care (including institutional and foster care) and later developmental problems. Studies from Rutter and Ainsworth have agreed with an attachment belief but have developed it to include situational variables such as previous home life, relationships, depth of bonding and care and reasons and reactions of the caregiver in dealing with an absence and return situation that can have an effect on the child above any basic separation. The length of absence, quality of care giving at bottom that absence and inherent flexibility and adaptability of infants as well as their capability to make sextuple attachments all need to be taken into account within this area.During the 1940s Bowlby made a connection between the attachment of an infant and mother and the shaping of an infants personality. From this an association was placed on the mother caring for the child instead of working. At this ti me welfare policies were focussed on a post state of war development of the family, and working freedoms afforded to women during the war were heavily curtailed as was war time nursery care. Popular policies suggested women should now be investing in their families as a duty.Thus if female workers were not being encouraged politically as an economic asset then child care policy provision was also diminished. Here Bowlbys ideas fuelled policy through popularising images of home based child care and family values by experts. Rutter later influenced changes through his findings of multiple attachment making in children although stressed that continuity of attachment was important. He was in embody of child day care as long as it was continuous and high quality, although a preference of parental care was suggested by Rutter.There is a difficulty in isolating variables which result in positive and negative attachments. Indeed some feminists argue that stay at home mothers are practic ally at risk of harming their children through an inability to cope and lack of support from immediate or extended family. Associated with this argument is that of the risk from domestic violence which increases closing off and effects the development of the child even if the primary caregiver is ever present. From the 1950s an increased development of the nuclear family has been argued to provide a collectiblel function. In this the family is seen to provide close personal relationships and act as an economic strategy for development and to maintain stability and control.Such evolution of the family has been characterised by transience and isolation of family units from the extended family and community itself. A close knit extended family can provide more options for child care and support whereas otherwise external methods of care are needed. If maternal proximity with the under-fives is crucial then entire communities would be maladjusted by design and this clearly cannot be held across the board.Again the discern of consistency and quality over quantity of child care can be bought to view. Popular media along with welfare policies have in recent years sought to not only improve childcare and rearing practices, provide support, normalise differing household situations such as lone parent, and expansion and regulation of child day care provision. Feminist theory has been at the forefront of womens re- entry to work force as well as a normalisation of disunite and single parent or co-habiting (step) households. On the other hand the feminist push for womens employment rights has resulted in inevitable contradictions as women are pulled in both directions, and indeed even the act of having children at all is currently considered heavily in an economic light due to the increased cost of living and childcare fees.Nowadays we can see increased governmental intervention in support of the family in the form of lengthening maternity and paternity and parenting care rights, childrens rights, value credits, flexible working, child care and pre-school provisions and subsidies, and the importance of family environment and child security building in issues of fostering and child protection. Thus the family by some(prenominal) shape of form it may take in the UK is heavily affected by the economic requirements and government policy provision. It is now the norm for women to work as well as be responsible for child care and household upkeep. Subsequently it is the norm for mothers to be separated from babies before their first birthday due to monetary need and often this has to be longer than desirable due to a cycle of economic need and high child care fees.Overall, I can conclude that Bowlbys ideas although outdated have persisted through the decades and still influence child rearing and day care decisions. It can be seen as dogging in governmental policy to this day for example, in maternity leave being extended to cover twelve months le ave Bowlby would surely support this move. In all Bowlbys ideas of attachment and primary parental care giving remain pervasive and are ingrained within the family unit in the UK, although an acknowledgement of multiple attachments and quality of child care are now highlighted over simply the primary care givers proximity.

Detecting of Ransomware using Software Defined Networking

Detecting of Ransomw ar using Software Defined NetworkingAbstract Ransomware is a major(ip) weapon for cyber-extortion. The handed-down signature- base detection no longer holds good against modern, sophisticated malware that employs encryption techniques and social engineering. This paper investigates the use of Software Defined Networks (SDN) to detect the illicit communication among infected PCs (ransomware) and their controller known as the Command Control (CC) server. SDN provides unique opportunities to detect venomed DNS requests (associated with malware) and where possible block ransomware controls requests, and thereby counteract ransomware triggering. In this oblige we mostly panorama at detection at commercial or business scenarios, where the selective information handled are much more sensitive and might superstar to m bingletary loss.Index Terms Ransomware, cyber-extortion, Signature-based detection, Software defined Networking.Cyber-Extortion malware derriere b e trace back to three decades earlier 1. It all started with the malware named PC CYBORG which was delivered by means of floppy disk. The reports of modern malware known as ransomware were started in early 2005. Since then ransomware has developed into more sophisticated method of attack to extort money from batch as well as the companies. Ransomware prat make a huge impact on businesses, especially if it strikes mission-critical systems. The attacker forces the companies to birth-out money in the form of bitcoins which flowerpot be anonymous and not so easily traceable. If refuse to pay, they threaten to destroy the data. This is a profitable business model to cyber criminals as the companies and people melt to pay out to retrieve the data 2.It is estimated that the pay-outs to ransomware is close to $1 billion an year as per IBM for 20163. This is just known pay-outs and it crosses more than $1 bn if all the pay-outs are considered. The anonymity of the attacker and necessit y of the victim makes it one of the popular attacks to extort money, especially from major tech companies and targeted businessmen. The ransomware is not specific to a single OS platform. From past a few(prenominal) years, the ransomware have been developed for different platforms like linux, Mac OS and popular one emerging now a days is for android.In general, the working of modern ransomware is as follows. First, a user machine is infected using various attack vectors for example, clicking on malvertisement, downloads from non-trusted sites, phising, spam, etc. Second, the victims system or the stored data is encrypted (locked), based on the type of ransomware. The modern versions of the ransomware roll in the hay encrypt storage drives such as cloud storage, Dropbox, and shared network devices. As a result, quadruplicate systems on the network can get compromised, by a single infection. Figure 1 shows the general working of the symmetric and irregular crypto ransomware.Fig. 1. (left )Symmetric and (right) asymmetric crypto ransomwareAs the ransomware evolves, some well know malwares have come into business, such as CryptoLocker, CryptoWall, TeslaCrypt and Locky have been widely utilise and updated.Detecting these ransomware before the payload activates and start encrypting is rattling difficult 4. Figure 2. Shows that only half of anti-virus scanners provide protection for this new malware, even after several days of a new attack world circulated.Fig. 2. Time to detect new malware by antivirus vendors.Recent study shows that the ransomware is become successful as the prices are tailored as per companys or countrys ability to pay 5. If the ransom isnt paid within the expiry of the ransom note, the ransom usually doubles. This instils fear of losing the files or pay higher. This let company or the person musical note it is easier and less expensive to pay the ransom and get back the files rather than reporting it and trying to find a solution for i t. This makes it important to come up with mitigation techniques to stop this from continuing andThe ransomware developers are constantly improving their product which makes it hard for developing long lasting countermeasures. With large number of devices that are getting connected on the internet like the Internet of things, the ransomware is being developed to multiple devices.Most common method of detection of ransomware, infact any malware, is signature based detection. Hence most of the experts suggest keeping the antivirus scanners up to date 6. But as we have seen from the earlier that not many vendors give out updates that regular. besides with the use of encryption techniques and social engineering, it easily evades the defence in firewall and email spam filters. Hence the detection of entry of ransomware into the system or the network is becoming much more difficult.One more commonly used method of detection is by identifying the extensions. For example, many use extensi ons like .locky, etc. But this can be masked by encryption techniques.Microsoft advices the best way to tackle ransomware is by having a tested reliable backup to escape the damages of the ransomware 7. Although this is one of the best methods, creating and maintaining backups for huge organizations can be really expensive and time consuming.Now let us take a look at few of the current implementations to detect ransomware in commercial or business network as they are the major victims because of the data they hold. Majorly used method is implementing products which use drug user Behaviour Analytics (like Varonics or DatAdvantage). This works on the baseline of normal activity and if there is any other abnormal activity, an consternation would be sent to the administrator. The major disadvantage with this is any other legitimate activity which is not mentioned under normal behaviour was reported which led to receiving of lot of false positives about the activity. opposite method us ed was to detect venomous activity by monitoring changes in File Server resource manager (FSRM), function built into Windows Servers. By using canaries, writing unauthorised files can be blocked. This helped in developing PowerShell to block unauthorised user access.Most of the currently used techniques work moderately well with the symmetric crypto ransomware. They tend to be less efficient with the asymmetric crypto ransomware. In this article we look at one of the basic approach that can be taken to mitigate ransomware with the use of Software Defined Networking (SDN). This method is mostly useful in companies or a small network with a system administrator to monitor the network dealing.Proposed method is based on findings after analysing CryptoWall ransomware 8. But this can be applied to other types of crypto-ransomware, such as Locky TeslaCrypt, etc, which communicates with the Command Control (CC) servers. The primary intension with this proposed method is to cut-off the connection between the victim and the CC systems. Without connection to CC the encryption process is not departure to be initiated and thus saving the victims system.With the use of Intrusion detection/Prevention systems(IDPS) or firewalls that are commonly used to filter and detect malicious data, it is precise hard to give timely response to such threats as there is lot of data that it encounters because of the number of devices that is connected onto the internet now a days.In this article we take a look at two SDN-based mitigation concepts. We can call them SDN1 and SDN2. Both of them rely on dynamic blacklisting of representative servers used for connecting to the CC server. However for this method to be efficient, it is needful to have up to date list of all the malicious proxy servers that are previously identified.In this method of mitigation system, it is necessary to develop a SDN application to cooperate with the SDN controller. The controlled provides all the data ne cessary for analysis. After the detection of threat, the network can be configured to block all the malicious activity and capture suspicious traffic for investigation. This leave alone also help in recovering symmetric key fruit if the ransomware uses symmetric encryption based ransomware.The functionality of the SDN1 is a simple switch. The switch forces all the DNS traffic to be forwarded to SDN controller for inspection. All the responses are compared and evaluated with the database that determines the list of malicious proxy servers. If the domain name extracted from the DNS is present in the database, the response is discarded or blocked to not let it reach the proxy server. This eliminates the process of encryption on the victims system. An alert is sent to the system administrator about this issue for further investigation.The potential drawback of SDN1 is time taken. The DNS traffic from both legitimate and malicious hosts is delayed as each response is checked with the blacked listed domain database. The SDN2 enhances the performance of SDN1 while addressing this issue. As most of the DNS responses received is legitimate, the SDN2 introduces custom flow. This forwards all the DNS response to intended receiver and only the copy of the response is sent to the SDN controller. While the DNS responses are processed, the controller compares the domains with the ones available on the database. If a blacklisted server is found, the victim IP is extracted and all the traffic between the CC server and the victim IP is dropped and an alert is sent to the system administrator.The pictorial representation of both SDN1 and SDN2 are shown in Figure 3.Fig. 3. SDN-based applications, SDN1 and SDN2. prototype testbed of the SDN networkMajor advantages of using SDN based detection techniques is that it can be used to detect both symmetric as well as asymmetric ransomware. As mentioned earlier without the connection between victim and CC server, the infected host w ill be able to retrieve the public key and accordingly will not be able to start the encryption process.As we have seen earlier, this method requires a database that contains all the currently known and used malicious proxy servers. This is the major disadvantage of this method. Currently the developers of this method have a database of about 70,000 malicious domains. But this wont be sufficient as the attackers will be looking for new domains to evade detection. Also methods have to be checked frequently and loopholes need to be fixed as the attackers would seek to knead any loopholes if found.There are researches that are taking place to detect the ransomware using honeypot techniques. The SDN can be included into the honeypots to further enhance the speciality of the detection. Alongside with the SDN, the companies will have to develop an Incident Response team 6. This team should make plans to tackle the issues according to the importance of the systems and also be effronter y training to be equipped with the necessary steps to take in case of an attack which slipped from the SDN controlled.In case of an attack, steps should be taken to contain the ransomware just to the affected system and it doesnt spread to any other system on the network.It is also important to take a backup of the entire necessary and sensitive files in a secure and tested location. This help in restoring the work quickly in case of unseen attack on a critical system.Also one of the most important developments in ransomware is that now it is not just delivered as a Trojan, it is being developed in a way that it can replicate its code onto the removable devices and network drives.This makes it important to educate and train the employees and the staff about the dangers of ransomware and methods that it can be brought in to the network like the spam emails and social engineering 9. Also companies should discourage the policy of bring your own device (BYOD). Staff a being more alert a bout the malware makes is very difficult to launch any attack.As we are looking to develop methods to detect and prevent ransomware, new type of ransomware is emerging that threatens to issue all the data online, instead of destroying them, if not paid before the ransom note expires. This is makes it more necessary to develop more sophisticated methods of detection to prevent ransomware attacks.Also as this is an SDN based security application, further research can be undertaken to broaden the spectrum of detection and prevention of other types of malware and attacks like DDoS attacksTo efficiently repugn ransomware, it is important to break the business model of the ransomware developers. With the reduced income to the ransomware developers, they will have to shut down the proxy servers which in turn help in quicker detection of newer developers.The best protection is to prevent infection. This may be tough to achieve and hence in this article we have taken a look at 2 types of S DN based security application that can be implemented to improve protection against ransomware. These rely on up to date database of malicious proxy servers which needs to be updated constantly but once detected, the application works efficiently.We have also discussed that it is achievable to break the connection between the victim and the CC server, with the help of SDN application, to make the encryption impossible.Furthermore, we have seen that it is necessary for the companies to actively invest time and money in training people to develop a sense of security at the workplace to reduce the attacks.We have also discussed that this SDN based application need not be limited to detecting ransomware. This can be further developed to detect and prevent other malware, detect attacks based on the network traffic characteristics or detecting malware based on pattern.ReferencesN. Hampton and Z. A.

Preventing Effects of Global Warming

Preventing Effects of Global WarmingRachel TomsettHow potbelly we as a species prevent the continued effects of orbiculate warming and to what bound has irreversible damage already occurred?Global warming, in addition known as climate transpose, describes the rising temperature of the atmosphere and ocean. Throughout all of earths account climate has been a precise fluctuate factor (for example the ice age). However if you take into account how some(prenominal) organisms on earth obtain evolved into their unchangeable habitats and how each one depends on their habitats to survive, fluctuations will be much more(prenominal) catastrophic now, especially to humanity and the animals humanity relies on e.g. Honeybees. The main ca expenditure of global warming is thought to be the result of humanities actions, for example Co2 emissions (from cars and other transport) interfering with the O-zone layer ca utilise, Dewoodlandation in rainforests (from workers creating space for ca ttle grazing) and country ( numerous fertilizers contain nitrous oxide which is harmful to the O-zone layer, and sheep/cattle produce large amounts of methane which is also a harmful nursery chemical). In the century atmospheric temperature has risen 1- F and Oceanic temperature 0.18-F (1). Whereas this may not necessitate an immediate effect in the future this will cause extreme weather conditions such(prenominal) as droughts, wildfire and mass flooding/intense rainstorms. Although to an extent we can already see this source to happen, for example if we look into the statistics of how many acres of land per category ar destroyed by wildfire (see figure 1) we can clearly see an incline in the more recent years as Co2 emissions and temperature also increase( see fig. 2). This would make sense as dryer conditions make an easier/quicker path for fire to spread. However looking into the source of figure one we can see updated statistics which indicate a drop in the number of wildf ires after this graph was made, although this could be due to human intervention and preservation regularitys.As easy as being a mass inconvenience for humanity these effects could also be very damaging to other species on earth, this is why scientists are focused on looking into/exploring alternative methods to try and lessen the rate of climate change. If conditions were to change too much or too rapidly many species would not be able to survive or adapt into this new climate and in relation we may see a mass nursing bottle neck in species, or in the most extreme cases extinction. On the other hand we may see a certain species flourish and call on in this new environment which may lead to a tip/collapse in an eco-system which would cause other species to suffer. Not to indicate if climate change carries on at the rate its climbing earth may soon be inhospitable to humanity, our future generations.Although scientists know global warming is irreversible there are still certain methods humanity can adapt to lessen the rate. For example scientists work been looking into alternate zipper to try and back up more heap to switch from fossil fuelled animation to a more eco-friendly and renewable energy sources. 21.3 billion tons of CO2 (carbon dioxide) are produced by the burning at the stake of fossil fuels per year (2), which obviously contributes to the concentration of CO2 in the atmosphere and in turn notwithstanding damages the O-zone layer but these new energy sources use natural methods which are easily replenished such as solar energy, wind energy and hydro energy which do not produce any harmful emissions. This is obviously a great solution to lessen the rate of climate change if more people started using these methods of energy we could cut emissions down by the masses and slow the rate of Global warming a considerable amount. These solutions are relevant in the fact that they dont release greenhouse gases and harness natural situation withou t any mass destruction and harm to the environment and habitat around it.However methods such as these are overpriced and arent as cost effective as non-renewable sources, so economically it is not the best choice, especially for poorer countries. On the other hand because non-renewable sources are advance close to running out (unless new sources/mines are found), the price for nonrenewable energy is beginning to climb higher and higher (due to less availability and more demand), which in turn (and partly due to advancing technology) basic renewable energy sources are becoming cheaper and more obtainable, for instance towns people may occupy to have a certain number of solar panels on their roof due to the declining prices (see fig 4). In just one year the price for 16 solar panels to be installed has gone from 15000 to 7500 which is a 50% saving (see Fig. 3). However methods on a larger scale, for example wind farms, (to generate a real(a) amount of energy) would exigency anyw here between a dozen or hundreds (see fig. 5). Which obviously, again, would costs a great amount and not many countries could afford them jumper lead to more economical problems especially since sometimes they come with instillation prices and taxes.One environmental problem that would face the panels is in countries like the UK. The weather is extremely shifting and sunlight is at its most intense in summer when less energy is needed, say for heating because the weather is warmer and for lighting because the days are longer in summer. The ratio between summer and winter inputs is unfavorable. However other countries like France and USA have a much more constant input. (3).A social/economic problem with solar panels is that if one would want to produce energy on a larger scale the panels would need to be in a very large place with access to sunlight. These are called Photovoltaic power stations (or solar farms). The placing also contributes to how much power these panels generate the slope of the location, the axis in which the panel is mounted on, hemisphere, ect. This of course will take up large amounts of field space that may have been previously used for farming (see fig 6) or recreation. In which case the farmer of company could see a loss in profit from the lose land (as farming cant be done under these panels unlike wind farms) and the civilians could argue that the land is being wasted. As far as the panels effect on human life, past the implications, are next to none. However, other wildlife which may have resided in the open space before it became a solar farm will have had their habitat destroyed and would have had to migrate somewhere else, which would cause a disturbance to the wildlife.Another implication of renewable energy is a social issue establish around Wind farms, many people oppose having wind farms/ turbines around their homes/towns. Theresa Groth and Christine Vogt have done a reputation (4) in which they mailed a questionnaire to different town and counties to gather an idea of what the general opinion is on Wind turbines and their usefulness, many responded to the questionnaire by saying turbine status near their residence increased uncertainty and concern of them, next to no one focusing on the positive outcomes like clean energy/no emissions. Others claim that the visual appearance of the turbines ruins the landscape. As for the actual risk to humans from these wind farms a report was published in 2007 by the U.S. field query Council (5),it concluded that although low-frequency vibrations are not well understood in their relation/effect on humans, and that of course sensitivity to the vibrations varies greatly among people, wind turbines would not be a major concern/threat to people beyond a half-mile. Of course there are still people/scientists who disagree but further research need to be done on Humans and their sensitivity to low frequency vibrations/noise. And for the effect on other living organi sms beside humans filth animals such as cattle and grounded wildlife (deer/badgers) do not seem to mind the turbines and carry on with grazing/hunting (see fig. 6). However, flying wildlife e.g. birds and bats seem to have a higher mortality rate around areas with wind turbines, presumably due to flying into the structure or spinning blades. However according to studies and surveys birds have the ability to detect the wind turbines and anyway more research shows wind turbines have not reduced bird populations so much so that there will be a noticeable effect (unbalance in the food chain/eco system.).To get a further understanding of how the climate is changing scientists use a number of methods to obtain data they can evaluate and compare for more answers. For example the US Global Change Research Programme (USGCRP) publishes a National Climate Assessment which looks into how climate affects different regions of the US. It also observes the long/short term changes in climate and th e ozone layer using satellites and monitoring icecaps run and sea levels. It also aids scientists in predicting any future changes to the environment and if we are at risk of being vulnerable to natural disasters. For example by studying these satellites that collect all this data scientists can observe change in conditions such as the rising of waters upstream to a colony in Bangladesh. The satellite will take pictures from space and use their altimeter to measure the distance between itself and the river surface revealing the change in height of upstream locations and seeing as the data is nearly instant allows scientists to look at potential flooding risks downstream closer to the village ect. (6).This recent method of using advanced technology is much more reliable and quicker than using a ground based network, taking into account how the ground network doesnt extend as far upstream as the satellite and information isnt as instant as the satellite. An example of a ground based network is the Flash Flood Early Warning System which was introduced in 2013 to give warnings to locals about an upcoming flash flood. However this service only provided a small amount of warning time (3 hours) which is a very small amount of time compared to that the satellite can provide. Although this is not a measure method it is the best scientists can do without interfering with the local towns or river path. Which would have an effect on the locals and their crops as the water source would either be diverted or be behind flooding barriers.An alternative method to renewable energy and a disaster forecast is the reconstruction of forests. Trees are amenable for absorbing Carbon Dioxide and converting it to Oxygen which then is released back into the atmosphere. However, in these past couple of decades deforestation has become a major industry and 12-15 million hectares of forest are lost each year(7).There are a number of reasons for this making space for cattle farming, harv esting wood for fuel and extrajudicial logging. This isnt just harmful for our atmosphere but handles of animals are in danger or threatened because of their habitat being destroyed. So as an alternate method I think that scientists should look into claiming more forest as protected/private land and look into the replantation of forests where ever possible. Not to mention looking into cracking down on illegal activities in the forests (logging/hunting) and enforcing punishment. Although this may create a social implication, more so in tropical isolate regions, as some small villages believe certain animal skin to be medicine and use the wood for heat and fuel, also only living(a) on cattle and crops in the spaces where trees used to grow. Perhaps another suggestion would be roof top gardens in cities, which will create space for plants to photosynthesise and alter carbon dioxide for more oxygen. Although the building would have to approve planning permission and would take a ce rtain amount of time to grow, and would need a lot of care I think it would be an interesting method to try and reduce the carbon concentration in the atmosphere, interfering with the O-zone layer.Another alternate method that would greatly help with cutting humanities carbon emissions is if more people purchased and used electric cars. Electric cars do not produce tailpipe emissions and are much more eco-friendly, they have been introduced before but never really caught on as technology was lacking and there were limited charging places. Even now the stamp battery life does not last as long as say a petrol fuelled car and the charging time takes so much longer than a simple refuel, but if scientists were to look into and experiment more with the concept and perhaps have a charging station at every petrol station people might begin to adapt to the idea and in turn lessen their carbon emissions. Although battery powered cars are considerably more expensive than the vernacular petro l/diesel ones, battery prices are beginning to decline, much like the solar panel prices. So perchance in the future it will transport on just as well as the panels.Bibliography1)http//ocean.nationalgeographic.com/ocean/critical-issues-sea-temperature-rise/ Sea Temperature Rise-National Geographic- unusual author-Unknown date published- Date used 20/3/152) http//www.environmentlaw.org.uk/rte.asp?id=192 Human activities-Environment Law-Unknown author- Unknown date published- Date used 20/3/153) (Book) Man and The environment-Cambridge Social Biology Topics-Alan Cornwell-First published in 1983-date used 20/3/15Because this book is quite old I cant find much information or the book its self-there for Im beginning to question its reliability mainly for the fact its 32 years old and a lot of advancement has been made in the past 30 years and climate and attitudes have also changed. However after lots of searching I found that the author was Head of the Science Division at Bulmershe C ollege of Higher Education in Reading, Berkshire. It was published by the Press Syndicate of the University of Cambridge which leads me to believe that even though it is old it is accurate of its time and was valid and maybe still is valid today, as the author clearly had scientific knowledge and access to studies and information. It has lots of picture evidence as sources to back up their points and is very in depth, including diagrams of cycles and chemical equations of relevant reactions. Whilst researching and validating a table they had used in the Air pollutant section (page 37) Deaths Due to Urban Smog I dogged to research the numbers and dates to see if they were similar. Looking at figures it is clear to see they were rounded to the nearest thousand (Place London) and again London had many more deaths than sensitive York or Belgium, which supported the table in the book. Over all I can conclude that this is quite a reliable source.4) http//www.sciencedirect.com/science/ar ticle/pii/S0960148113004370 outlandish wind farm development Social, environmental and economic features important to local residents-Science Direct-Theresa M.

An Essay on The Withered Arm, by Thomas Hardy -- English Literature

An Essay on The Withered ramp up, by Thomas audaciousThe past is a foreign country. They did things differently there.The Go Between by L.P. Hartley.Thomas Hardy, a Victorian novelist, based his stories on experience ofgrowing up in rural Dorset. Growing up there, he became familiar withthe language, customs, practises and stories of the country folk.These stories draw up on his experiences enabling him to write WessexTales. Among many pieces of work is The Withered Arm. The WitheredArm is a well-crafted short-change story written in the prose format. Thequote above portrays what pre-twentieth century literature shouldembrace good literature should be perspicacityable, realistic andsignificant to all deal from any era. In this essay I am going todescribe the ways in which Thomas Hardy has made his short story, TheWithered Arm interesting to the modern reader.The Withered Arm is about Rhoda Brook, a dark milkmaid whoretaliates on her lovers beautiful new wife, Gertrude, after her lover, Farmer Lodge abandons her and their illigimate son. Hardy hascarefully structured all the elements of a short story making TheWithered Arm interesting and perennial to the modern reader. FarmerLodges denial of the affair with Rhoda and the neglection of his soncauses Rhodas plotting revenge. Employing the character, seerTrendle, brings the involvement of witchcraft and supernatural powers,giving the plot a paranormal twist. The public execution of The male childimmediately grasps the interest of the reader because we learn that inthe Victorian times, committing such a petty crime, there is a massivepenalty. We also learn that the lives of the hoi polloi were so habitual,that they thought of executio... ...led and brings out the best in his stories, yet his language maybea little hard to understand for a modern reader. I do not find thecharacter in The Withered Arm a problem at all because although someof those characters no longer exist, Rhoda, Conjuror Trendle, Hangman,i t is still interesting to read about their daily lives and how thingswere for them after all good literature should be giving the readerand insight on how things were. make up though the reader may not alwaysagree to the philosophies hidden in his themes, it is captivating toimagine how a Victorian writer can refer to such things. I think thatThe Withered Arm is a fantastic example of pre-twentieth centuryliterature because not only is it interesting, but it gives us aninsight on the different lives of the different characters and yet isstill interesting to the modern reader.

Transformation and Mixture in Moby-Dick :: Moby Dick Melville

Classroom discussions of Moby-Dick often result in a heightened awareness of Melvilles depictions of dichotomy in nature for example, the contrasting toss away and sea respectively represent heaven and hell and the foul-smelling whale in Chapter 92 produces a fragrant and valuable substance called ambergris. But interlingual rendition Melvilles Moby-Dick only as an exercise in duality limits the scope of this complex original. Melvilles contemporary, Margaret Fuller, also seems aware of the confining notion of duality and states in Woman in the Nineteenth CenturyMale and female represent the two sides of the great radical dualism. But, in fact, they are perpetually passing into nonpareil another(prenominal). Fluid hardens into solid, solid rushes to fluid. There is no wholly masculine man, no purely feminine womanNature provides exceptions to every rule (Fuller 293-4).Fuller explains that duality is a limiting and artificial concept, especially when used to describe nature. Tran sformation and mixture are concepts that more accurately characterize both nature and the publications of Fuller and Melville. Multiple perspectives are ideal for these authors, as is evident in Melvilles multifaceted Ishmael. At the end of the novel only Ishmael survives because he is able to view life and nature in an all-encompassing fashion.Melville is preoccupied with coffins in this novel, exploring the connection that this object has to nature -- an object that is made from nature (wood) and holds another part of nature (a body) after a natural progression has taken place (death). Melville seems fascinated by this odd and frequent custom of humankind of burial bodies inside a wooden box. Even seamen who remain unattached to land, such as Queequeg, desire such a burial at sea. This coffin root word begins within the first few lines of Chapter 1, Loomings, when Ishmael thinks of funeralsWhenever I find myself growing grim about the mouth whenever it is a damp, drizzly Novemb er in my soul whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral procession I meet (Melville 3).This statement in the beginning of the novel introduces the reader to the coffin imagery that Melville uses throughout Moby-Dick and serves as the metaphor for transformative mixture throughout this paper.In Chapter 110, Queequeg in his Coffin, Chapter 126, The Life-Buoy, and the Epilogue, Melville explores many different and interesting representations of Queequegs coffin. Queequegs coffin cannot be defined only in terms of duality it is not simply just a coffin and a life-buoy.
