This paper uses microdata to evaluate the impact on the steady-state unemployment rate of an increase in maximum benefit duration. We evaluate a policy change in Austria that extended maximum benefit duration
and use this policy change to estimate the causal impact of benefit duration on labor market flows. We find that the policy
change leads to a significant increase in the steady-state unemployment rate and, surprisingly, most of this increase is due
to an increase in the inflow into rather than the outflow from unemployment. 相似文献

Strategic group literature has generated a significant amount of research over recent decades. However, the rivalry implications
of strategic group have remained unclear. This paper analyses rivalry and strategic groups in the house building industry
in a small town from a cognitive approach. We consider rivalry as a subjective and directional phenomenon. Estimating rivalry
as the direct identification of competitors we try to explain whether similarity affects rivalry and what factors make a company
a “rival”. Results show that perceived rivalry is strongly related to size, past performance, subjective similarity and strategic
group structure.

Therapeutic residential care (TRC) is the name given to specialized children's homes for treating cases with severe emotional and behavioural problems that have been placed in residential care. A recent international review has revealed great diversity in the referral criteria of cases and in the models of intervention carried out. The goal of this study is to describe the population treated in these types of facilities in Spain and the therapeutic coverage given. The sample is made up of 215 young people in children's homes, of whom 93 are in TRC. The cases referred to TRC have been in residential care for less time but have gone through a greater number of placements. These young people also exhibit more problems of drug use, and there is a larger percentage of clinical‐range cases in the Child Behaviour Checklist scales of attention problems and aggressive behaviour. Nevertheless, the results of logistic regression indicate that the only variables that significantly increase the probability of being referred to TRC are drug use and changes of care placements. With regard to therapeutic care, there is a higher percentage in the TRC group receiving psychiatric care, and the sessions are also more frequent. 相似文献

In this study, classical and Bayesian inference methods are introduced to analyze lifetime data sets in the presence of left censoring considering two generalizations of the Lindley distribution: a first generalization proposed by Ghitany et al. [Power Lindley distribution and associated inference, Comput. Statist. Data Anal. 64 (2013), pp. 20–33], denoted as a power Lindley distribution and a second generalization proposed by Sharma et al. [The inverse Lindley distribution: A stress–strength reliability model with application to head and neck cancer data, J. Ind. Prod. Eng. 32 (2015), pp. 162–173], denoted as an inverse Lindley distribution. In our approach, we have used a distribution obtained from these two generalizations denoted as an inverse power Lindley distribution. A numerical illustration is presented considering a dataset of thyroglobulin levels present in a group of individuals with differentiated cancer of thyroid. 相似文献

In statistical analysis, particularly in econometrics, it is usual to consider regression models where the dependent variable is censored (limited). In particular, a censoring scheme to the left of zero is considered here. In this article, an extension of the classical normal censored model is developed by considering independent disturbances with identical Student-t distribution. In the context of maximum likelihood estimation, an expression for the expected information matrix is provided, and an efficient EM-type algorithm for the estimation of the model parameters is developed. In order to know what type of variables affect the income of housewives, the results and methods are applied to a real data set. A brief review on the normal censored regression model or Tobit model is also presented. 相似文献

There are multiple factors which contribute to the development of the individual’s personality. Many of these factors have been amply discussed in traditional theories of personality Jonnation. An area that has been neglected in these discussions has been the role that poverty and ethnic and cultural factors may have in this regard. This paper offers a discussion of these issues with special emphasis on cultural, ethnic, and socioeconomic factors which tend to characterize the lives of Latino and Black individuals. Recommendations are made for a re-evaluation of the traditional theories of personality when applied to poor and minority individuals. 相似文献

This study compared the memory, attention/concentration, and executive functioning of 12 women with histories of child sexual abuse with a control group of 12 women without childhood abuse. Participants completed a neuropsychological test battery and various instruments assessing post-traumatic stress disorder and dissociation. The child sexual abuse group had lower performance than the control group on long- and short-term visual and verbal memory and presented more limited performance on executive functioning tasks. Functioning in these areas showed a negative correlation with post-traumatic stress disorder and dissociative symptoms. These findings suggest that child sexual abuse is associated with memory and executive functioning deficits and supports the idea that people with trauma histories and increased post-traumatic stress disorder and dissociation symptoms may have alterations in neuropsychological functioning. 相似文献

This article argues for the idea of different moments in Vygotsky's work while highlighting combinations of ideas and concepts that were particularly emphasized in distinct moments of his work. After Vygotsky's death, these moments were not considered a theoretical system in development, either in former Soviet psychology or in Western interpretations of his work. Vygotsky's legacy seems to have been mostly reduced to one concrete focus of his work, mistakenly identified as cultural-historical theory. The overemphasis of selected aspects of Vygotsky's work resulted in an overshadowing of other ideas that have remained relatively “unknown” until fairly recently. In this article, previously underemphasized elements in Vygotsky's psychology, such as emotions, fantasy, imagination, personality, and the generative character of human psyche, are emphasized. A consideration of these elements offers new and refreshing alternatives to Vygotsky's legacy. These previously underemphasized elements are markedly represented in Vygotsky's first and third moments. Furthermore, in the third and final moment of his work, the category of sense opened up a completely new perspective for a systemic and complex approach to understanding the human mind. 相似文献

AbstractThis study used an experimental procedure to evaluate the effects of fear of negative social evaluation (FNSE) on courtship strategies and the ability to interact with the opposite sex. 108 university students participated in this study with a mean age of 19.6. Prior to the experimental procedure, FNSE levels were measured. Then two photographs of people of the opposite sex were shown, one more attractive than the other, and the participants were informed that they would meet one of them. Levels of anxiety and self-presentation motivation (SPM) were measured before the planned interaction. Results show that people with low levels of FNSE have positive expectations of reciprocity when they are about to meet a person that they find attractive. Women, but not men, with high levels of FNSE report higher SPM with less attractive people than with more attractive people. High levels of FNSE are associated with a loss of calm in the situation of meeting a person of the opposite sex. Implications of these results are discussed in the context of courtship strategies. 相似文献

This article examines black-white residential segregation in micropolitan areas across the South. Micropolitan areas are newly defined urban clusters with a core population that ranges from 10,000 to 50,000. By shifting the focus to the nonmetropolitan South, we take debates about the “American dilemma” back to a historically important terrain of black-white relations that few scholars have systematically examined in the post-Civil Rights era. Using the most recent census, we find that the dynamics of residential segregation in our sample of micropolitan areas reflect both important opportunities and constraints. In contrast to their counterparts in metropolitan areas, blacks in the nonmetropolitan South face “only” moderate levels of segregation. Surprisingly, southern micropolitan areas afford greater opportunities for spatial assimilation to the least economically advantaged blacks as well as those who are more advantaged. Perhaps most importantly, this finding holds for micropolitan areas located in the historic Black Belt as well as elsewhere; however, several patterns emerge that suggest a set of barriers to spatial assimilation similar to those facing African Americans in metropolitan areas. In sum, our analysis clarifies the complexities of black-white segregation in the “New South/Old South,” pushing scholars to more systematically map the distinct trajectories of “American Apartheid” across time and place in the United States. 相似文献
