How important is academic performance in obtaining a tenure‐track position in academic science? I use data on Korean biochemists and analyze them from both institutionalist and gender perspectives. In so doing, I illustrate the ways academic performance and gender interact with one another to maintain a gender barrier for Ph.D.s entering an academic career. The main findings are as follows. First, academic productivity did influence the job market outcomes, but the male scientists benefited from publications in both SCI and non‐SCI journals, whereas the female scientists benefited only from those in SCI journals. I also found a positive effect of overseas doctoral training only for the female scientists. Such analysis suggests that women as a minority in academic science are pressured to prove their legitimacy through more rigorous criteria of academic performance. Thus, ostensibly gender‐neutral rules of academic performance can be applied in such a way as to maintain gender inequality.  相似文献

By restricting the number of age groups to two and by introducing continued fractions, the dynamics of populations with deterministically changing vital rates are completely specified at all times. Explicit expressions for the sequence of the product of population projection matrices are given. From these, relative age distribution and reproductive values to any desired accuracy are obtained as functions of the vital rates. Thus, the results given in this paper are stronger than any existing weak ergodic theorems.  相似文献

Symmetry and separability of a covariance function are common assumptions to simplify the modeling effort of spatial–temporal processes. However, many studies in environmental sciences show that real data have complex spatial–temporal dependency structures resulting from lack of symmetry or violation of other standard assumptions of the covariance function. In this study, we propose new formal tests for lack of symmetry by using spectral representations of the spatial–temporal covariance functions of regularly spaced spatial–temporal data. The advantage of the proposed tests is that classical analysis of variance (ANOVA) models can be used for detecting lack of symmetry inherent in spatial–temporal processes. We evaluate the performance of the tests with simulation studies and we apply them to air pollution data.  相似文献

One central determinant of global environmental change is the continued expansion of personal consumption levels. In order to more fully understand the relationship between consumption and environmental degradation, the determinants of consumption must first be identified. Prior research in this area has focused on economic factors, primarily personal disposable income and population demographic characteristics. The role of cultural factors, including advertising, has been actively mentioned in theoretical analyses of the driving forces of individual consumption. However, this has not been empirically tested. In this article, we conduct an analysis of the impact of advertising on consumption levels in the United States. We start with a theoretical discussion of the literature on advertising and consumption. Based on this literature, we establish three hypotheses regarding the relationship between advertising expenditure and personal consumption. These hypotheses are then tested using time series analysis over the time period 1900–2000. The results show that advertising significantly impacts overall consumption and that these effects vary by type of consumption. We conclude with a discussion of the implications of this analysis for further research into the driving forces of global environmental change.  相似文献

This article examines second-generation Asian Americans' explanations of the significant influences on their own religious identities. Data include interviews (N = 73) with college-aged Asian Americans from different religious traditions and ethnic backgrounds. Respondents viewed families as the most significant influence on current religiosity. Mothers and fathers were mentioned most often, followed by extended kin, siblings, and relatives, who acted as what we call "reinforcers,""substitutes," or "contrasts" to the roles that parents played in religious socialization. These roles occurred along two religious configurations within families: heterogeneous or homogeneous degrees of religious commitment and religious affiliation. Directions for future research and contributions to the religious transmission literature follow.  相似文献
