Three decades ago, planned obsolescence was a widely discussed ethical issue in marketing classrooms. Planned obsolescence is topical again today because an increasing emphasis on continuous product development promotes shorter durables replacement and disposal cycles with troublesome environmental consequences. This paper offers explanations of why product obsolescence is practiced and why it works. It then examines the ethical responsibilities of product developers and corporate strategists and their differing responses to this problem. Pro-environment product design and marketing practices and innovative government policies may alleviate the problem over time. However, given the current lack of understanding about consumer replacement and disposal behavior, it is questionable as to whether these practices and policies will be sufficiently informed to be effective. Thus, marketing scholars have a significant opportunity to contribute to sustainable durables product development.  相似文献

Abstract.  The objectives of this paper are threefold. First, we critically survey and analyse the different methodologies that have been adopted in the rankings literature. Second, using journal articles included in the ECONLIT database and on the basis of two criteria – one based on citations and the other on perceptions of journal quality, we rank economics teaching departments in Australia and New Zealand for 1988–2002 and 1996–2002 and for individual academic economists for the periods 1988–2002, 1988–1995 and 1996–2002. Furthermore, we identify individual star performers and recognize them in a designated 'Hall of Fame' for 1988–2002. Third, our methodology enables us to make international comparisons on total and per capita bases. Previous multi-country ranking studies in economics do not rank economics departments. They provide rankings based on total publications in economics in universities regardless of whether the economists are in the economics departments or in other departments. Thus, no rankings on per capita bases are provided. We correct this shortcoming by providing total and per capita rankings and analysing the correlations between total and per capita rankings. This is the first study to examine whether the size of the economics department matters with regard to productivity.  相似文献

Derivative mortgage securities have proliferated since planned amortization and floating rate CMO classes were introduced in late 1986. Other recently created derivative securities include reverse floaters and deep-discount bonds of CMOs, CMO residuals, and stripped and senior/subordinated passthroughs. These securities, which are derived from fixed-rate mortgages, were created to meet investor demands for maturity certainly, interest rate and prepayment hedging, and enhanced credit. The rapid growth of derivative securities reflects expansion of the investor base for fixed-rate mortgages. It also suggests that these mortgages will continue to be a viable housing finance instrument in a volatile interest rate environment. For the future, the increased creation of derivative securities will make the secondary mortgage market more efficient, facilitating the funding of fixed-rate mortgage originations.The substance of this paper was originally written in late 1987 and many of the specific data reflect that time period.  相似文献

Despite major investments in community-based tourism to diversify economies, reduce poverty and improve life quality in the Caribbean, little is known about what conditions lead to resilience and sustainability. Sustainability from a resilience theory perspective is the likelihood an existing system of resource use will persist indefinitely without a decline in social and natural resource bases. Undertaking activities to enhance resilience and sustainability improves a system's ability to persevere, adapt and learn to meet challenges from unanticipated economic, political or natural events. This study investigated six communities in the Commonwealth of Dominica, all part of a seven-year community tourism program, and examined residents' perceptions of the social, institutional, economic and ecological resilience of their community, and therefore the resilience and sustainability of community tourism development. It used a new scale using eight steps suggested by Devellis' scale development methodology. Data indicated moderate to low resilience in all four domains across the communities. This suggests that communities should invest in strengthening social bonds, developing capacity in local institutions, in diversifying the tourism product and controlling infrastructure development. Indicators measuring trust, networks, local control, flexible governance, leakage prevention and controlled infrastructure development emerged as important in assessing social–ecological resilience and sustainability.  相似文献

The present paper reports findings from a study on coordination in three research settings—academic, cooperative-government, and industrial—and discusses their implications for research management. The study ascertains the relationship between coordination and research effectiveness, and examines how coordination operates and is attained in research settings. Two hypotheses regarding the relationship between coordination, research effectiveness, and integration of research staff are advanced and tested on research groups in the three research settings mentioned above. The results support the hypotheses and indicate that the relationships occur very generally regardless of the setting in which the research is conducted. The findings are discussed in terms of their implications for research management and in particular the attainment of coordination in research settings.  相似文献

Abstract

Hunting participation, as indicated in the 1983 Nationwide Recreation Survey, is examined to determine the relationship between age of first hunting experience and adult level of participation. A statistically significant association between these two variables is found. In addition, more than 83 percent of those who hunt began their involvement by 18 years of age. The findings have implications for future hunting participation and the provision of programs for hunters.  相似文献
