Research report - Essay Example Prior to the split up, the entire central Asian region fell under administration of Moscow. Moscow’s administration had structured mechanisms meant to ensure equitable distribution of water and energy resources within the region (Murodbek 261). However, independence from Soviet Union ushered in unprecedented challenges to the nations under consideration. Main rivers supplying domestic and agricultural water to the five nations originate from mountain ranges within Tajikistan and the neighboring Kyrgyzstan, and then flows downstream through the other remaining three nations and finally drains into Aral Sea. From a rational perspective, the two nations within the upstream region should ensure undisrupted flow of water to nations lying on the downstream region. On the other hand, downstream nations are rich in oil and gas energy sources. This means that they will return the undisrupted water supply favor by pumping oil and gas to Tajikistan and Kyrgyzstan (Murodbek 261). This pla n worked efficiently under the Soviet Union administration before secession of Central Asian sovereign territories. Despite the fact that this resource sharing strategy sounds simple and logical, current state of affairs between the nations involved does not conform to this strategy. Consequently, lack of conformance to equitable sharing of resources has led to technical hitches within economic, social and political relationships between nations in the entire region. As an illustrative example, generation of hydro-electric power by nations in the upstream region like Tajikistan as met vehement disapproval from downstream counterparts (Murodbek 263). At this juncture, this essay will develop a comprehensive analysis on causes and effects of the water-energy crisis. In addition, an extrapolation of the theme will examine existence of similar problems in other nations around the globe. Nations lying within the upstream section of Central Asia, especially Tajikistan engages in intensive agricultural activities as their main economic activities. In the recent past, necessity to expand the nation’s economic sector led to expansion of agriculture through irrigation. As a result, Tajikistan diverted large volumes of water from the two main rivers serving the region into the irrigated tracks of land. This increased supply of water to farms was not going to be seasonal. The huge tracks of land lie within an arid and semi-desert regions of the nation. This means that irrigation requires sustained amount of water supply to meet agricultural production demands. In this case, extensive irrigation of cotton and wheat farms remained as the central economic activity in the lower part of Tajikistan (Murodbek 263). In addition, other nations including Kazakhstan tapped river water in the middle of flowing channels conveyed them directly to their farms. In this regard, every nation tried to expand its agricultural sector by utilizing the only available water from the two m ain river channels. Consequently, this caused a pronounced shortage of total water flowing down stream. This means that economic and social activities of people living within the affected nations would experience difficulties (Murodbek 265). At this juncture, expansion of irrigation fed agriculture featured as one of the main cause in the water-energy crisis in Central Asian region. Apart from irrigation, energy generation through hydro-electricity played a significant role in causing the water-energy

Computer systems - Essay Example But due to the fact that interface of most computer systems has limited range of expressions, users has no opportunities to interact with them as with real people. Current tools, such as email, mailing lists, chat rooms, discussion phorums have substantial shortcomings. Their interface is designed only for delivery of simple ideas, without emotions, gestures or face expressions. Of course people can use so-called smiles (primitive pictures with emotions, such as smile or sadness), but every system has its own predefined set of smiles and does not allow user to insert custom image instantly. At the same time in a physical world people can easily express emotions in a discussion over a meal or a drink, meeting up at a conference or having a special offer pointed out to you by behaviour of a stranger. Social information in a physical world is transmitted on many levels. Most of these levels are lost in digital environment, hence socially blind. Therefore need of expression of social information arises, for example mood, condition, some feelings. So people can see emotional reaction of their interlocutors, not only what they express in words. This social information may be applied to knowledge management to make users' activities visible to others. The realist approach involves trying to project social... The realist approach is a straightforward answer to the question; it minimizes the difficulty of producing and interpreting social signals. However current technology places very strict limits on the resolution of teleconferencing and video space systems. The mimetic approach tries to represent social cues from the physical world, as literally as possible, in the digital domain. The mimetic approach is exemplified by graphical MUDs and virtual reality systems, and uses virtual environments and avatars of various degrees of realism to mimic the physical world. Work here ranges from attempts to implement a virtual physics to the considerably looser representations of social information found in the 2-D and 3-D avatars found in various graphical MUDs and 3-D VRML worlds. While the use of mimetic representations decreases some of the bandwidth requirements of such systems, in this sort of system social signals must be consciously produced via users manipulating their avatars. The abstract approach involves portraying social information in ways that are not closely tied to their physical analogs. Exemplars of the abstract approach include AROMA, the Out to Lunch system (which uses abstract sonic cues to indicate socially salient activity), and Chat Circles (which uses abstract visual representations). This approach also includes the use of text to portray social information. Text has proved surprisingly powerful as a means for conveying social information, so the abstract approach scales well, both textual and abstract graphical representations being relatively compact. (Erickson and Kellogg, 2002) 3. Using your knowledge and experience, explain how the application of context and domain modelling could be used to help establish a
