  • Increasing physiological and psychological impairments with age does not mean that ageing is equivalent with illness, diseases or dependency. In fact, earlier studies could not explore that a type or the pathogenesis of diseases is only caused by the ageing process (Steinhagen-Thiessen & Borchelt 1996). Brody and Schneider (1986) distinguished between age-dependent and age-related diseases. Age-dependent diseases are involved in the ageing process and cause the exponentially increasing mortality risk with advanced age, for instance heart and cerebrovascular diseases.

  • This primer gives a brief glimpse of available data on health care costs, and summarizes the impact of spending growth on various parts of society. The National Health Expenditure Accounts (NHEA), the source for several of the analyses shown, present the costs of care by type of health service or product (such as hospital care, physician services, or prescription drugs), sources of funds (such as private insurance, Medicare, Medicaid, or out-of-pocket by the individual patient), and types of sponsors (private business, households, and government).

  • These demographic changes are taking place in developing countries alongside increasing mobility and changing family structures. Industrialization is eroding long-standing patterns of interdependence between the generations of a family, often resulting in material and emotional hardship for the elderly. The family and community networks in many developing countries that had formerly provided support to the older generation have been weakened, and often destroyed, by rapid social and economic change. The AIDS pandemic is also significantly affecting the lives of older people.

  • More needs to be done now to get traffi c off the roads and on to rail. Real prices have to be charged that refl ect the real costs caused by polluters. The wider use of market-based instruments will bring about more cost-oriented pricing and fairer market conditions, which would lead to modal shift, behavioural changes, and help pay for improvements in rail infrastructure.

  • In addition to return and diversification goals, public pension funds target investments to benefit the economic climate where their beneficiaries live and work. Often public employees retire in their state. For example, the New York State and Local Retirement System (New York State Common) has 77 percent of retirees and beneficiaries that remain New York State resi- dents (NYSLRS 006). Pension funds therefore adopt targeted investment policies to seek competitive returns while also allowing a fund to create healthy communities benefiting their retirees and beneficiaries.  ...

  • There has been only modest improvement in the productivity of indigenous cows, cross- breds or buffaloes over the last two decades in India (Table 1). The average daily milk production data at 6.52 kg for crossbreds, 2.10 kg for indigenous cattle and 4.44 kg for buffaloes (NSSO, 2007) suggests that the productivity of these animals is far below their genetic potential.

  • States have largely abdicated regulatory authority for electronic media—television and radio—even though a review of federal pre- emption law suggests that only transmissions into a state from out of state or on cable are preempted. In other words, broadcasts that originate within a state are subject to state regulation. Although a state may claim such jurisdiction without a provision that makes the authority explicit, an explicit statement of jurisdiction is substantially preferable.

  • Predicting Needs as a Buyer. It is difficult to describe precisely the level of resources required to run an ex- periment or job. Depending on the inputs to a program, the ideal level of resource consumption can vary dramat- ically. Moreover, there is a tangible penalty formisestimating resource need, since these bids are made in advance of when the resources will actually be available. In order to match enough buyers with sellers, current market-based resource allocation schemes batch allocations into blocks of time.

  • Water resources could in principle be managed by several users as common property resources. In the absence of effective mechanisms for co-management at the watershed or river-basin level, however, water resources often become open access. Conflicts often arise between upstream and downstream users. Irrigators at the tail end of a large irrigation system may have the formal right to water, but their share may be taken by farmers near the head of the system, who may even have switched to higher value and more water consumptive crops through collusion with irrigation officials.

  • The tactile examination of the breast is best performed with the patient re- cumbent with her arm raised above her head. A small pillow under her upper back can further distribute the breast tissue over the chest wall. Palpation is performed using the base of the fingertips in small circular motions with vari- able depth. Recall that breast tissue extends beyond the region usually defined by a bra cup.

  • Research over the last 30 years confirms that air pollution causes adverse effects on community health and the environment and imposes a real cost on the community. Economic theory shows that for resources to be used and distributed efficiently, all costs and benefits of an activity need to be adequately considered. However, in many cases, the costs of air emissions are ‘external’ to the production and consumption decision- making processes, as they are imposed on the wider community rather than the polluter.

  • The process of counting correct answers began by assigning a value to the responses to each question (Table 6). Where countries have substituted questions, or reworded them, we have also given a value of 1 to a correct response and 0 in all other cases. In the case of a country with fewer than 8 financial knowledge questions we have rescaled each score as necessary (typically multiplying by a factor of 8/7).

  • These guidelines are important particularly for the design of organisations that will interface with the SME sector. Additionally, important general factors in supporting the development of an entrepreneurial society are positive entrepreneurial personal role models for individuals to follow, entrepreneurial attitudes among all relevant stakeholders, local empowerment, a greater belief in ‘trust’ than in regulations and the encouragement of initiative at all levels. The education system is commonly regarded as the starting point for the creation of enterprise culture.

  • Under the old rules, the only way to get “published” was to have your press release “picked up” by the media. We’ve come a long way. The Web has turned all kinds of companies, non-profits, and even rock bands and political campaigners into just-in-time and just-right publishers. Organizations – the new publishers – create press releases that deliver useful information directly onto the screens of their buyers. Until recently, nobody ever thought of companies as publishers; newspapers and magazines published the news. But that’s all changing.

  • In Southeast Asia there have been found a lot of rubber-bearing plants. Most of them are members of the one family, Apocynaceae, but there are also some important species from other families, like Ficus elastica Roxb. and Bleekrodea tonkinensis Dub. & Eber., which both belongs to the family Moraceae. The first seeds for the cultivation of the rubber were sent to Asia, Sri Lanka, in 1876, but these first attempts to grow the rubber trees (Hevea brasiliensis Muell. Arg.) were not successful. It was not until 1877 when 22 rubber trees were plated in Singapore. From...

  • And in fact, that neuroprotection is indeed possible is demonstrated beyond doubt by the neglected survivor of that host of neuroprotectant agents: hypothermia. Hypothermia was demonstrated to be effective in a score of animal experiments, and it has now become recommended intervention in out-of-hospital cardiac arrest. Hypothermia is not a drug, but it demonstrates that neuroprotection is a reality, not a myth. Besides, it obviously shows that animal experiments were right, humans treated with hypothermia fare better than untreated ones, just like animal studies had predicted.

  • Living squamous cells are found just below the stratum corneum. These cells have moved here from the lowest part of the epidermis, the basal layer. The cells of the basal layer, called basal cells, continually divide to form new keratinocytes. These replace the older keratinocytes that wear off the skin's surface. Cells called melanocytes are also found in the epidermis. These skin cells make a brown pigment called melanin. Melanin gives the skin its tan or brown color. It protects the deeper layers of the skin from some of the harmful effects of the sun. When skin is exposed...
