Social remittances: migration driven local-level forms of cultural diffusion

"Many studies highlight the macro-level dissemination of global culture and institutions. This article focuses on social remittances--a local-level, migration-driven form of cultural diffusion. Social remittances are the ideas, behaviors, identities, and social capital that flow from receiving- to sending-country communities. The role that these resources play in promoting immigrant entrepreneurship, community and family formation, and political integration is widely acknowledged. This article specifies how these same ideas and practices are remolded in receiving countries, the mechanisms by which they are sent back to sending communities, and the role they play in transforming sending-country social and political life." The data concern migrants from the Dominican Republic to the Boston area of the United States.     

The determinants of modern Maltese emigration

The author evaluates studies by Huw R. Jones and Russell King concerning the determinants of emigration from Malta and tests a new set of migration functions using cross-sectional and time-series data for the inter-censal years 1957 to 1967. Jones and King concluded that emigration was influenced more by socio-demographic factors than by economic forces. In the present article, the author concludes that economic factors did influence the decision to migrate from Malta. The policy implications of these findings are also considered.

Physician career development: toward building a model

Virtually no managed care organization provides a comprehensive and integrated program for physician career development. That's the principal finding of a survey we carried out in Spring 1994 in which we interviewed several individuals who have proven instrumental in the creation of career development programs at their managed care organizations. We started our research with the hypothesis that career development programs for physicians--frequently the most highly paid category of employees and the ones often most directly involved in the delivery of health care--should parallel the mission of the organization. In many of the organizations we surveyed, the mission included clinical excellence, managerial competence, research, teaching, community service, and building shareholder equity. While each organization offered some component of career development--usually clinical improvement and management development--very few offered programs that fostered the continued professional development of physicians in other aspects of their missions. In most cases, even in organizations with stronger career development agendas, the programs were passive and were rarely linked to the overall "corporate" goal of the managed care institution. This critical disconnect makes it extremely difficult for health care organizations to develop a workable system of accountability for their career development programs.     

Making the journey into the networked enterprise, Part 2

In the May issue of Physician Executive, the authors described the difficulties other industries have had with vertical integration and why so many corporations have abandoned it for other organizational structures. In this second part of the series, they explore the ways health care organizations can make the shift into integrated delivery systems, avoiding the trap of the hierarchical, vertically integrated monolithic structures that will become the dinosaurs of the future.     

Politics and Scientific Expertise: Scientists, Risk Perception, and Nuclear Waste Policy

To study the homogeneity and influences on scientists'perspectives of environmental risks, we have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. We found significant differences ( p 0.05)in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a)perceive the greatest risks from nuclear energy and nuclear waste management; (b)perceive higher levels of overall environmental risk; (c)strongly oppose imposing risks on unconsenting individuals; and (d)prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. We also found that–independently of field of research–perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices.     

Codes of ethics and firm size: A stakeholder approach to strategic planning

A firm's capital budgeting and strategic planning decisions have the potential to affect many groups of people called stakeholders. A stakeholder is any group or individual who can affect or is affected by the achievement of the firm's objectives. This study examines whether the presence of a code of ethics that specifically addresses capital budgeting/strategic planning decisions will significantly raise the awareness of social responsibility during the long-run planning process. This study also examines whether firm size is associated with the awareness of social responsibility during the long-run planning process. Support was found that a code of ethics that addresses long-range planning is associated with higher awareness during the planning process. Firm size was not found to be statistically different.     

Ecology of urban lawns under three common management programs

Turfgrass lawns are a central part of urban and suburban landscapes throughout North America and are often managed using repeated applications of chemical fertilizers and pesticides. These inputs are expensive and may negatively affect ecological processes in lawns. Therefore, we evaluated the influence of three most common lawn care programs on ecological characteristics of turfgrass lawns. Twenty-eight home lawns, separated into 3 groups based on the lawn care program (professional, do-it-yourself [DIY], and no-input), were studied. Data on lawn quality, weed and insect infestation, disease incidence, soil nematode community, soil nitrogen pools, microbial biomass (MBN), and soil organic matter (SOM) were collected. Results indicated that professional lawn care resulted in the highest aesthetic lawn quality mainly due to better weed control, compared to DIY and no-input programs. However, professional and DIY programs negatively affected MBN and SOM pools and enhanced disease (rust) severity. No significant differences in soil nematode population and nematode community indices across the three programs were found, indicating no differences in net ecosystem productivity among the three programs. Overall, soil nematode food web in turfgrass lawns represented a disturbed food web compared to natural grasslands and forest ecosystems, irrespective of the lawn care program used.
