Attachment Representations and Parental Memories of Incarcerated Fathers

This article presents the findings of a study designed to apply attachment theory concepts to a group of incarcerated fathers in a minimum-security facility. Participants in this convenience sample were either immediate graduates of a 13-week parenting skills program or currently involved in the parenting skills program. This exploratory study sought to examine first, whether the Adult Attachment Interview (AAI) could effectively determine current mental representations of attachment relationships with a group of incarcerated fathers. Secondly, to gain further knowledge of this population regarding the impact of familial aspects by use of a survey measure, along with two other standardized measures were implemented. Thirty-eight voluntary subjects participated in the intensive AAI in scheduled individual sessions, completing child abuse additional measures. Differences among a three-category adult attachment classifications and five-category attachment classifications were identified. Both qualitative and quantitative results are discussed.     

Immigrants and the public sector budget – accounting exercises for Sweden

Net contributions to the public sector budget in Sweden are investigated using large samples of foreign born and native born. The accounts build on various assumptions including that expenditures on public consumption are allocated according to the age of the person. The results indicate that during the period 1983 to 1992 net contributions of immigrants deteriorated. Upon arrival to Sweden, immigrants on average place a burden on the public sector budget but after a few years this no longer applies. Refugees initially put a larger burden on the public sector budget than other immigrants, but such a difference declines with years since immigration.

The employment adjustment of male immigrants in England

In this paper the employment performance of native and foreign born men in England is examined, using 1993–1994 data from the Quarterly Labour Force Survey of the United Kingdom. Chiswick's (1982) hypotheses of immigrant employment adjustment are investigated using logistic regression analysis. We show that there are interesting and important employment effects arising from immigrant characteristics. Recent white immigrants experience a transitory employment disadvantage. However non-white immigrants never attain employment equality with native born white men. Education, potential experience, family characteristics and country of birth are also found to be important determinants of employment. Received: 13 September 1998/Accepted: 15 July 1999     

The Impact of Joint Responses of Devices in an Airport Security System

In this article, we consider a model for an airport security system in which the declaration of a threat is based on the joint responses of inspection devices. This is in contrast to the typical system in which each check station independently declares a passenger as having a threat or not having a threat. In our framework the declaration of threat/no-threat is based upon the passenger scores at the check stations he/she goes through. To do this we use concepts from classification theory in the field of multivariate statistics analysis and focus on the main objective of minimizing the expected cost of misclassification. The corresponding correct classification and misclassification probabilities can be obtained by using a simulation-based method. After computing the overall false alarm and false clear probabilities, we compare our joint response system with two other independently operated systems. A model that groups passengers in a manner that minimizes the false alarm probability while maintaining the false clear probability within specifications set by a security authority is considered. We also analyze the staffing needs at each check station for such an inspection scheme. An illustrative example is provided along with sensitivity analysis on key model parameters. A discussion is provided on some implementation issues, on the various assumptions made in the analysis, and on potential drawbacks of the approach.

阶段性信息披露和风险资产定价

上市公司的内部人通常拥有比其他投资者更多的信息,同时他们有义务把所知道的信息透露给投资者。但是在现实的金融市场中,信息披露者通常会采取对其最有利的信息披露方式。不同于以往的信息披露模型,我们假定内部人所披露的信息必须是正确而且全面的,但他们可以在一定程度内调整信息披露的时机。本文研究了这种情形下的资产均衡价格,并且分析了其经济含义以及在金融监管方面的实践意义。
