Productions Possibilities
Production possibilities frontier
A production possibilities frontier is a reflection of one of the fundamental principles of economics, namely that scarcity is inherent to the economic condition -- no person or nation can have 'everything,' and choosing one balance of productive resources necessitates a loss in some other area if productive resources. The frontier shows the tradeoffs in the production of goods. "To understand this concept, assume that there are two goods x and y, that resources are fully employed and common to both goods, and that technology is fixed. To produce more y, resources (e.g. labor and capital) must therefore be moved from x to y. This means that the production of more y causes less x to be produced" (Production possibilities, 2009). Improvements in technology can result in the frontier as a whole moving outward, as can a greater investment of resources, and a greater emphasis on goods with capital accumulation (this means that some consumption must be given up today so that more capital goods can be produced) (Production possibilities, 2009).
Conversely, the frontier might move inward if the technological possibilities of a nation become more limited. The nation might experience a natural disaster, for example, or production facilities, due to aging and lack of reinvestment might become less efficient during an economic contraction. Less investment of resources into production and a greater emphasis on goods for consumption, rather than capital accumulation can also cause the frontier to move inward. Finally, there might be less of a demand for the goods of the nation because of a general change in consumption patterns, so although the balance of goods may be equal, as a whole there may be less production of the exported goods of a particular nation in response to a downturn of demand (such as Italy's slowing of pasta production during the low-carb craze, even though this might be a major export good for the nation which it can produce in mass qualities, with relatively little drain on other productive resources).

However she warning device should always be checked and monitored in a way that it is guaranteed effective in sending signals way ahead of the disaster. A good tsunami warning system would be well-placed instruments with good communications that are able to send data immediately and effectively. The information has to be made available within ten minutes via satellite... (Daily Post, 2005) Thus the warning system must be installed in almost,
An effective public transportation system has several positive effects including reducing local and regional energy expenditures; reducing dependence on fossil fuels and foreign energy supplies; improving the quality of life in the region as a whole; linking New Orleans with surrounding regions more effectively to stimulate clustered economic growth; and reducing income disparity by increasing access to jobs, public services, and educational institutions. An effective transportation system is also
A b) Event management People react differently when faced with disaster, some may respond and follow the disaster response plan without a problem, other may forget key instructions and follow their own plans, the most dangerous situations however, are when individuals freeze and fail to act when disaster strikes. Response before, during and after a disaster can be the difference between life and death. (Bridegan et al., 1997) Failure to heed
natural disaster, such as a tornado, the responsibility for communicating with and caring for the population falls on elected officials and civic leaders. Having an emergency communications network in place is essential. Communications services provides an emergency communications reserve based on a variety of volunteer skills, including administrative, technical and operational, for emergency tactical, administrative and logistical communications between the city, its agencies, and county government. With the report of tornado
Disaster Preparedness Plan: Georgia has been an area threatened by some of form of natural disaster that has a huge negative impact on the well-being of its residents and the personnel and financial resources of the emergency response agencies. The most common natural disaster that occurs in this area is tornadoes that have terrorized both the rural and urban areas while making everyone in danger of their perils. In the recent
Disaster recovery refers to the IT components of the business that, in times of a disaster, need to be safeguarded so that business can be continued. Disaster recovery is more a preventive plan set in motion prior to the organization and implementation of the business than a series of actions that are followed once the disaster hits the company. Given that most companies are, to a large extent and in
