In recent years, two new theoretical perspectives on poverty in modern welfare societies have emerged: the perspective of ‘cumulative disadvantage’ and poverty individualisation. Both perspectives challenge traditional class-based poverty definitions. This article notes certain limitations that pertain to the relatively few empirical tests that have been performed to support these theories. The purpose of the article is to demonstrate that the results obtained depend largely on the type of poverty definition applied (income or deprivation), the actual data used (national or comparative) and the extent to which these data represent an observation period that is long enough to provide a reliable basis for testing the theories in question. The article concludes that because only few Danes experience long-term poverty and social exclusion, the combination of class and individual biography is important. In other words, structural conditions and, to a lesser degree, group risks drive individuals to the social margin. 相似文献

This article reports some relevant results from a recent survey of the corporate planning practices of a number of leading British organizations. The sample spanned turnovers from £2000m. Within this range, the functional areas involved show considerable variation: for example, 95% of companies perform financial planning, but only 52% production planning. Organization too, quite naturally, displays great variety: thus one company operates with only a single planner whereas another employs thirty. Ratings are quoted for the main advantages and disadvantages of corporate planning as assessed by the chief executives; in general, the benefits dominate. 相似文献

Starting age and subsequent birth intervals in cohabitational unions in current danish cohorts, 1975
This paper presents some main results of an investigation by life table methods of birth interval data in cohabitational unions (marriages as well as consensual unions) in current Danish cohorts. Our results confirm previous findings that an early age at the start of recorded exposure to childbearing risk is indicative of a rapid pace and high level of subsequent fertility. The analysis modifies previous results and adds several new details regarding cohort trends and the effect of parity at the start of reported cohabitation. For each parity within a period of cohabitation, fertility differentials by reported starting age seem to have diminished from our older cohorts (of age up to 49 years in 1975) to our younger ones (of age less than 30 years in 1975). There are indications of a dramatic change in childbearing behaviour following the arrival of novel attitudes to non-marital cohabitation and childbearing in Denmark about 1967. 相似文献

Fractional regression hot deck imputation (FRHDI) imputes multiple values for each instance of a missing dependent variable. The imputed values are equal to the predicted value plus multiple random residuals. Fractional weights enable variance estimation and preserve correlations. In some circumstances with some starting weight values, existing procedures for computing FRHDI weights can produce negative values. We discuss procedures for constructing non-negative adjusted fractional weights for FRHDI and study performance of the algorithm using simulation. The algorithm can be used effectively with FRDHI procedures for handling missing data in the context of a complex sample survey. 相似文献

This paper presents results of a Monte Carlo simulation of eight families of robust regression estimators in various situations. The effects studied include long-tailed error terms, measurement error in the independent variables, various spacings of the independent variables, different sample sizes and correlation between the independent variables. An estimator that combines the best features of several of the estimators is recommended for further study. 相似文献

In this article, we study how different transitional phases from childless cohabitation relate to education and educational resemblance of the partners. Using longitudinal population register data from Finland, we extend analyses of previous research to suit the conditions in societies where almost all unions begin before marriage and much childbearing takes place outside marriage. Educationally heterogamous couples are found to have higher separation risks than homogamous ones and a somewhat smaller tendency to marry or become parents. Winnowing consequently takes place also after parenthood, but the strongest effect is recently after couples have entered a cohabiting union. Traditional family formation behavior in terms of marriage before children is nevertheless much more common among higher-educated people. The share of unmarried parents is notably higher among lower educated, and they are much more likely to remain as unmarried parents. Hence, if parenthood is taken into account, marital status remains an important device for categorizing couples. 相似文献

Practicum instructors play a strategic role in assisting students gain the competence essential to effective practice. This article reports on a comparative study that tested the efficacy of traditional and experimental competency-based/task-centered methods of practicum instruction. It revealed that students taught under the latter method performed at a higher overall level of competence and had more confidence in their skills than those taught under the traditional method. 相似文献
