Current immigration research has revealed little about how immigrants compare to those who do not migrate. Although most scholars agree that migrants are not random samples of their home countries' populations, the direction and degree of educational selectivity is not fully understood. This study of 32 U.S. immigrant groups found that although nearly all immigrants are more educated than those who remain in their home countries, immigrants vary substantially in their degree of selectivity, depending upon the origin country and the timing of migration. Uncovering patterns of immigrant selectivity reveals the fallacy in attributing immigrants' characteristics to national groups as a whole and may help explain socioeconomic differences among immigrant groups in the United States. 相似文献

An operational definition for “rural area” is pivotal if proposals, policies and decisions aimed at optimising the distribution of resources, closing the gap on inequity between areas and raising standards of living for the least advantaged populations are to be put in place. The concept of rurality, however, is often based on alternative and conflicting definitions, requiring clarification of the underlying theoretical model. Traditionally a geographical area has been classified as rural by taking into account either the number of inhabitants or population density. Two kinds of problem are raised with this approach, however, namely: it is inherently difficult to describe such a complex concept as rurality with a single variable; and reducing the concept down to a rural/urban dichotomy by setting a non-universal cut-off point does not usually provide an accurate account of reality. Within the context of the rural–urban continuum, this paper has devised a rurality index for Spanish municipalities based on the 1991 Population, Housing and Household Survey. The index was built on a principal components factor analysis, giving rise to a single factor that is correlated to the aging of the population, economic dependency, farming, livestock or fishing-related employment, habitability of housing and population density. A score to each municipality was allocated. This index can be regularly updated thus enabling the progress of the concept of rurality to be monitored in our setting over time and then compared with other countries using the same methods. 相似文献

This review essay addresses Richard Swedbergs recent attempt to redefine the field of economic sociology. Grounding his position in Max Webers work, Swedberg advocates a type of economic sociology that not only focuses on social relations but also considers culture and interests, arguing that it is interests that drive action but that they are shaped by culture and enacted through social relations. We conclude our analysis with a consideration of the practical and empirical implications of this new approach for the study of economic life. 相似文献

The spark of small groups: An analysis of the developmental logic and dynamics of a consultancy process In the recent past large group interventions have gained increased attention in the systemic consulting literature. In contrast to this tendency, this paper focuses on the significance and effectiveness of small group interventions in business consultancy.Based on a qualitative analysis of a consultancy process, the effectiveness of small group change processes is documented here: Unlike large groups, small groups not only are far more likely to succeed in developing structures which differ from the existing organizational structures, they moreover are much more likely to develop a strong identity which helps them generate the power necessary for change. Especially in conflict situations and in situations where the pressures that are being put on an organization are increasing, small groups are more likely to maintain their identity, another crucial prerequisite for the initiation of a change process.The paper shows that consultancy systems, which differ in structure from the customer organization, are apt to serve as incubators for the development of strong groups within an organization. These small groups are able to push for organizational changes using conflicts process. 相似文献

What is Loss Aversion? 总被引:3,自引:0,他引:3
A behavioral definition of loss aversion is proposed and its implications for original and cumulative prospect theory are analyzed. Original prospect theory is in agreement with the new loss aversion condition, and there utility is capturing all effects of loss aversion. In cumulative prospect theory loss aversion is captured by both the weighting functions and the utility function. Further, some restrictions apply for the weighting functions involved in the latter model.We are indebted to Michèle Cohen and Peter Wakker for helpful comments. The suggestions of an anonymous referee have improved the presentation of the paper. 相似文献

This study found that moral reasoning predicts intention to act in an ethical dilemma, but that this behavior is not modified
by gender differences. Fishbein and Ajzen’s Reasoned Action model was used to predict intention to act in ethical dilemmas,
while the Kohlberg and Gilligan paradigms of moral reasoning were introduced as exogenous variables. The theory of reasoned
action model was found to be a good predictor of intention as hypothesized. Suggestions for further research are included.
This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献

This paper examines the effects ofpersonality variables and functional management role,either entrepreneur, manager in an entrepreneurialfirm, manager in a traditional firm, or small businessowner, on perceived business values. Functionalmanagement role had minimal discernible effects;personality variables differentiated entrepreneursfrom managers and produced many effects for ratings ofbusiness values. Results are discussed in terms ofMBTI and DISC theoretical constructs and theirimplications for entrepreneurship and management. 相似文献
