global warming research papers
Today, moreover, the absolute magnitude of the human misery that could be caused by climate change is much larger than it ever was because the human populations in virtually all regions of the world are much larger than they were before. Far more people would be affected by any given regional climatic change, and there is not likely to be any room in adjacent regions into which they could flee. The part of the ecosphere most sensitive to climatic change -- that is, the element most easily disrupted to the point of directly influencing human well-being -- is agriculture.

We might hope that the rather primitive state of knowledge concerning climatic machinery and how civilization may unintentionally be modifying it would discourage all groups from any deliberate intervention for a long time to come, but governments and other bodies have all too often shown themselves incapable of sensible restraint. Among the schemes that have been mentioned are: sprinkling soot on the Arctic sea ice to melt it, causing warmer but probably more snowy winters in the Arctic region; damming the Bering Strait, another way of causing the Arctic sea ice to melt, damming the Gulf Stream between Florida and Cuba; and creating a layer of stratospheric dust to counteract global warming due to carbon-dioxide buildup.

As understanding of climatic processes increases, the possibilities of misusing the new knowledge for weaponry become more awesome. The possibility of using chemicals to poke holes deliberately in another nation's ozone shield is now obvious enough, and intentional manipulation of storms and droughts does not seem entirely farfetched. Geophysicist Gordon MacDonald has emphasized the possibility that environmental warfare using climate modification could be carried out covertly over a period of years without the victims' being aware of the cause of their misfortunes. The potential for destruction, both intentional and inadvertent, associated with climatic warfare is second only to that of biological and nuclear war (and even this ranking may eventually prove to be questionable).
essay on importance of television
Nonetheless, we must not overvalue the importance of television as a medium of political communication. The crux of the matter of political socialization remains not the message-sending capacity of the socializer, but the receptor's comprehension of the message and his willingness to accept it. The direct effect of all political communication media on the political socialization of the population is questionable at best. Most people in Communist Eastern Europe would prefer to watch TV for the sake of entertainment and few recognize the messages for anything else except sheer--and to many people, stupid--propaganda.
research papers on television violence
The answer to this kind of a question will not be simple. As we saw with the problem of violence, some children exposed to television are more likely to be "at risk" than others. What children are likely to suffer what harm from food advertising? In the FTC hearings witnesses testified to the fact that health problems created by television often fall on those who have the lowest incomes thus who are unable to purchase additional foods to supplement the heavily sugared cereals advertised. Even if this were the only health effect of television advertising it cannot and should not be ignored. How great is the problem television creates in this regard, and what other actions could be taken to alleviate the problem?
essay on internet
Another aspect of troubleshooting in an internet is the lack of centralized control. An internet works because the participants agree to play by the rules--for example, not to install gateways that have problems and then refuse to fix the bugs when they are discovered. Much of the correct functioning of the internet relies on the goodwill of the participants. Once the problem discussed above is diagnosed, the hypothetical user from London will be notified that the people responsible for the offending gateway have promised to fix it when time permits. Fixing the problem is a complex procedure, however, and it may not be a high priority for the offenders because it may not affect them directly--perhaps it only affects the traffic passing through their gateway.

Large, ad hoc internets, naming is rarely handled in an organized fashion; different networks within the internet may have different (and conflicting) name services. There may be no centralized name service. A related problem is the management of network numbers and addresses. Addresses must be unique within an internet because as internets coalesce, the possibility of duplicate numbering schemes suddenly colliding becomes quite real. Even worse, there is no reason to assume that such a problem will be detected automatically. It is quite likely that the conflict will manifest itself in strange, erratic, inconsistent or otherwise incorrect behavior from the internet in response to certain requests, and the duplicate numbering will be recognized only when the cause of the odd behavior is finally tracked down.
internet privacy essay
The P3P is intended to allow sites to express their privacy practices and for users to exercise preferences over those practices. If a relationship is developed, subsequent interactions and any resulting data activities are governed by an agreement between the site and the user. After configuring privacy preferences, individuals should be able to seamlessly browse the Internet; their browsing software (user agent) negotiates with Web sites and provides access to sites only when a mutually acceptable agreement can be reached. Any requests from a service to store data on the user's side must comply with any outstanding P3P agreements.

W3C began P3P by designing the overall architecture for the P3P system and a grammar for expressing privacy practices. The P3P grammar specifies the types of clauses that comprise P3P statements. A P3P vocabulary is akin to a Platform for Internet Content Selection (PICS) "rating system"; the vocabulary specifies the specific terms that fit into the P3P grammar. For example, the P3P grammar specifies that P3P statements must include, among other things, clauses describing any data that are to be collected and the practices that apply to those data; a vocabulary includes a list of specific data practices that are valid in a practice clause.

Diagnosing problems within an internet is more difficult than diagnosing problems in a current, relatively simple dial-up connection. Since each packet is routed individually, dynamically and perhaps differently through a chain of networks and gateways in an internet environment, diagnosing problems will take more time and knowledge than one has any reason to expect from a public service librarian or data communications technician. The support staff in an internet environment needs an intimate understanding of several linear feet of protocol definition documents, gateways, routing algorithms and the idiosyncrasies of the various networks that make up the internet.
