Marital satisfaction has been psychometrically measured using many different instruments not soundly based on theory. The Revised Dyadic Adjustment Scale (RDAS), consisting of 14 items, is commonly accepted by researchers and practitioners to measure marital satisfaction but was not specifically designed to measure marital satisfaction. The Satisfaction with Married Life Scale (SWML), consisting of five items, is a short scale specifically targeted toward measuring marital satisfaction. An online sample collected from 1,187 couples throughout the United States was used to compare these instruments' correlation (r = .782), factor structures, reliability (SWML, α = .958; RDAS, α = .943), theoretical foundation, and validity. These instruments are on parity with each other when measuring marital satisfaction; however, each instrument yields implications for practitioners and researchers desiring to measure marital satisfaction.  相似文献

Countries of Central and East Europe are in a process of economic, social and political transition. This process provides a unique opportunity for cross-national studies in a context of social transformation and radical infrastructural changes. In the present study, we compared environmental behavior, and the factors affecting it, of citizens from five European countries with diverse economic and social status. Outcomes of the present survey suggest that people's attitudes towards environmental issues and economy-environment trade-offs can be considered reliable predictors, contrary to political attitudes which did not prove to be important determinants of environmental behavior. However, one should be aware of the differences in individual factors affecting citizens' environmental behavior, since the latter cannot be considered as a linear function of a country's development and modernization.  相似文献

The migration of political asylum seekers into the United States has long been a salient political topic; however, social scientists have yet to examine this process in its entirety and in the context of political changes since September 11, 2001. Previous research shows that humanitarian and strategic interests are important for decisions made by asylum officers but that research overlooks the decisions made by immigration judges. Here we examine decisions made by both asylum officers and immigration judges using data from a global set of countries, from 1999 to 2004. We find that the waning importance of human rights is more pronounced for asylum officers than for immigration judges after the attack on the World Trade Center. We also find that language heritage, specifically for asylum seekers from English‐, Spanish‐, and Arabic‐speaking countries, substantially affects acceptance rates made by both decision‐makers between the two time periods of our study.  相似文献

The increase in income per capita is accompanied, in virtually all countries, by two changes in economic structure: the increase in the share of government spending in gross domestic product (GDP), and the increase in female labor force participation. We argue that these two changes are causally related. We develop a growth model based on Galor and Weil (1996) where female participation in market activities, fertility, and government size, in addition to consumption and saving, is endogenously determined. Rising incomes lead to a rise in female labor force participation as the opportunity cost of staying at home and caring for the children increases. In our model, higher government spending decreases the cost of performing household chores, including, but not limited to, child rearing and child care, as in Rosen (1996) . We also use a wide cross‐section of data for developed and developing countries and show that higher market participation by women is positively and robustly associated with government size. We then investigate the causal link between participation and government size using a novel unique data set that allows the use of the relative price of productive home appliances as an instrumental variable. We find strong evidence of a causal link between female market participation and government size. This effect is robust to the country sample, time period, and a set of controls in the spirit of Rodrik (1998) . (JEL O4, E62, H11)  相似文献

New product success is predictable. This paper highlights the findings of an extensive study into new product success and failure, and pinpoints what separates winners from losers. The key success factors are: product superiority—delivering unique benefits to customers, upfront homework—before development gets underway, sharp and early product definition, a strong market orientation with constant customer contact and input, and quality of execution of key activities in new product process. Sadly many firms and new product efforts are lacking on these success factors. This points to the need for a more disciplined approach to product development. One solution proposed is the implementation of a stage-gate or formal new product process—a blueprint for the process from idea to launch. A generic stage-gate is outlined in the article. The experiences of managers in firms which have implemented such processes are investigated, and the performance results are positive: improved teamwork, less recycle, higher success rates and shorter cycle times.  相似文献

The process of conceptualizing and implementing significant change in complex organizations can be aided greatly through ‘future state visioning’, a set of processes for determining what and where you want to be by a future date. After developing ideas about the nature of the future environment facing the organization and the stakeholders who will be significant at that time, executives can articulate the values and principles which should guide actions leading to the future state vision. Examples from three organizations are used to illustrate the steps for successful use of the future state visioning procedure.  相似文献
