Demographics: people and markets   总被引:1,自引:0,他引:1  
The basics of demography are now basic to us business as well. Demographics combine demographic data with socioeconomic and geographic factors to help business and other managers know the market for their goods and services. This pamphlet explains market, product, and site analyses, discusses data sources and resources, and includes case studies involving major corporations. Post-war population trends have had an enormous impact on consumer and labor markets, bringing home to business the importance of taking advantage of demographic shifts. Advances in computerized access to data describing changes and increased consciousness of their economic significance has spurred the application of demographic knowledge by managers and the growth of the demographics information industry. The pamphlet describes the resources and methods of demographics including the creation and use of demographic data products.  相似文献

Manpower export and economic development: evidence from the Philippines   总被引:1,自引:0,他引:1  
The Philippines has actively pursued a policy of labor export with the expectation that it would relieve unemployment, augment the supply of skills, and relieve pressure on the balance of payments. It was also anticipated that the inflow of overseas workers' remittances would translate into increased investment, the sine qua non for economic development. However, recent evidence casts some doubt on the extent to which these goals have been achieved. Particularly in the areas of skill formation, there appears to be a significant discrepancy between anticipated and actual outcomes. Indeed, it appears that the labor export may reduce the supply of skills available since 1) many skilled and educated workers are taking jobs requiring skill levels lower than they possess, and 2) a large majority of returning workers do not want to take up employment in those occupations reliant on the skills they used abroad. There is conflicting evidence regarding the impact of labor export on Philippine industries. There is some anecdotal evidence that a few industries have suffered because of a loss of key workers. In general, however, it appears that unemployment is still quite significant in those occupations most heavily represented in labor export. Despite this observation, it may still be true that labor emigration is selective of only the best workers, implying a decline in quality of the work force and possibly productivity in certain industries. The export of professional, technical, and managerial workers is another issue. Unless it can be shown that these workers are in excess supply, it is not advisable to expand the number going abroad. Although their salaries may be higher, and hence their remittances greater, their loss can impose costs on indigenous industries well in excess of a any marginal gains. Remittances from overseas workers do constitute a relatively significant source of foreign exchange. However, the translation of remittances into investment has been restrained by the very low propensity of remittance recipients and returnees to undertake productive investment and by the diversion of remittances from formal banking channels into informal channels. Remittances which are being channeled through the formal banking sector constitute a potentially important source of loan funds, as well as providing a potential stimulus to indigenous industry.  相似文献

International labor standards take the form of Conventions and Recommendations that embody the agreements reached by a 2/3 majority of the representatives of Governments, Employers, and Workers of International Labour Office (ILO) member states. Originally designed to guard against the danger that 1 country or other would keep down wages and working conditions to gain competitive advantage and thereby undermine advances elsewhere, international labor standards have also been inspired by humanitarian concerns--the visible plight of workers and the physical dangers of industrialization and by the notion of social justice, which embraces wellbeing and dignity, security, and equality as well as a measure of participation in economic and social matters. ILO standards apply to workers generally and therefore also to migrant workers, irrespective of the fact that the general standards are complemented by standards especially for migrant workers. The social security protection of migrant workers has been dealt with in ILO instruments primarily from the angle of equality of treatment but also from that of the maintenance of acquired rights and rights in course of acquisition, including the payment of benefits to entitled persons resident abroad. The ILO Conventions on migrant workers and the Recommendations which supplement them deal with practically all aspects of the work and life of non-nationals such as recruitment matters, information to be made available, contract conditions, medical examination and attention, customs, exemption for personal effects, assistance in settling into their new environment, vocational training, promotion at work, job security and alternative employment, liberty of movement, participation in the cultural life of the state as well as maintenance of their own culture, transfer of earnings and savings, family reunification and visits, appeal against unjustified termination of employment or expulsion, and return assistance. ILO's supervisory mechanism consists basically of a dialogue between the ILO and the Government that is responsible for a law, regulation, or practice alleged to be in contravention of principles it voluntarily accepted. The control machinery is often set in motion by workers' organizations. The UN General Assembly is currently elaborating a new instrument designed to cover both regular and irregular migrant workers and their families.  相似文献

The article presents a case history of a gentrifying neighborhood, with special reference to the interplay between cultural artifacts and the forces of the political economy. In Boerum Hill, a neighborhood in Brooklyn, newly arriving middle-class homeowners used various political and cultural methods, including changes in nomen-clature, house tours, manipulation of boundaries and an attempt to secure historic landmark status, in order to enforce their definition of what the neighborhood should be. A countermovement then emerged on the part of older residents, who, using a different set of cultural referents (based on the notion of ethnic pride), sought to enforce a different definition. The author proposes that while the neighborhood is a socially constructed entity, the resources with which this construction takes place are unequally distributed. Moreover, as the notion of neighborhood has become increasingly politically salient in recent years, the author suggests that cultural conflicts over the definition of neighborhoods have become a feature of urban politics.  相似文献

Elective single mothers are adult, unmarried women who intentionally become mothers. This study utilized longitudinal data about 17 Caucasian, elective single mothers and their children to identify fathers' roles in these families, and to understand children's views of their fathers. These single mothers and their children resided for the first six years of the children's lives in father-absent households. By age six, most of the children had ghost fathers, whom they had never met or knew little about. The data suggest that the father often becomes a family secret, and that children may blame themselves for their fathers' absence.  相似文献

Between 1987 and 1990, the Robert Wood Johnson Foundation funded six service credit banking demonstration programs among the elderly in which participants delivered services in return for credits, entitling them to later service. This evaluation of the demonstrations found that these six sites successfully attracted elders for the delivery of household support services to a relatively old, frail population with potentially limited social networks. Evidence on the significance of the "credit" in attracting volunteers was mixed, but the programs have attracted new volunteers, and have not substituted for other volunteer activities. Program development has entailed considerable staff investment in volunteer support; programs are better understood as community membership organizations than as mechanical exchanges.  相似文献

The author argues that the burden of proof for the safety and efficacy of some medical devices properly lies with the manufacturers of the devices and with the providers who use them. The controversy over breast implants is used as a case for this shift in the burden of proof of safety and effectiveness.  相似文献

Pharmaceuticals traditionally have been viewed as a cost-effective component in medicine's technological armamentarium. The use of pharmaceuticals has been estimated to account for 6-8 percent of the nation's total expenditures on health care. The first wave of pharmaceuticals/biologicals that has been produced by the biotechnology industry has offered therapies that can provide much benefit to patients, but it has also raised concern about the cost of these new recombinant drugs. In addition to pricing, methods of promotion and modifications in the FDA approval process have raised concerns.  相似文献
