Formative Indicators and Effects of a Causal Model for Household Human Capital with Application

Dagum and Slottje (2000 Dagum , C. , Slottje , D. J. ( 2000 ). A new method to estimate the level and distribution of the household human capital with applications . Journal of Structural Change and Economic Dynamics 11 : 67 – 94 .[Crossref] , [Google Scholar]) estimated household human capital (HC) as a latent variable (LV) and proposed its monetary estimation by means of an actuarial approach. This paper introduces an improved method for the estimation of household HC as an LV by means of formative and reflective indicators in agreement with the accepted economic definition of HC. The monetary value of HC is used in a recursive causal model to obtain short- and long-term multipliers that measure the direct and total effects of the variables that determine household HC. The new method is applied to estimate US household HC for year 2004.     

THE EFFECTIVENESS OF FAMILY THERAPIES FOR SELECTED BEHAVIORAL DISORDERS OF CHILDHOOD

This article reviews the scientific evidence for the effectiveness of family-based aproaches in the treatment of selected childhood behavioral disorders. Although limitations certainly exist, family interventions have consitently improved child and, in some cases, parent functioning in families with children presenting with conduct disorder (CD) and autism. Parents and other family members also directly benefit from child-focused interventions, gaining in knowledge, child management skills, and attitudinal improvements. Longh-term follow-ups indicate that CD and autistic children achieved lasting gains. Similarly, the research on attention-deficit/hyperactivity disorder (ADHD) indicates that parent training improves child noncompliance and aggression yet does not consistently affect core symptoms of ADHD. There is no evidence that adding short-term family interventions improves ADHD child functioning beyond improvements from the use of psychostimulant medications. Some tentative support for family involvement in the treatment of childhood anxieties and fears is reviewed, but clear conclusions await future investigations. Finally, several methodological limitations and needed areas of research are discussed.     

Optimal detection of a jump in the intensity of a Poisson process or in a density with likelihood ratio statistics

We consider the problem of detecting a ‘bump’ in the intensity of a Poisson process or in a density. We analyze two types of likelihood ratio‐based statistics, which allow for exact finite sample inference and asymptotically optimal detection: The maximum of the penalized square root of log likelihood ratios (‘penalized scan’) evaluated over a certain sparse set of intervals and a certain average of log likelihood ratios (‘condensed average likelihood ratio’). We show that penalizing the square root of the log likelihood ratio — rather than the log likelihood ratio itself — leads to a simple penalty term that yields optimal power. The thus derived penalty may prove useful for other problems that involve a Brownian bridge in the limit. The second key tool is an approximating set of intervals that is rich enough to allow for optimal detection, but which is also sparse enough to allow justifying the validity of the penalization scheme simply via the union bound. This results in a considerable simplification in the theoretical treatment compared with the usual approach for this type of penalization technique, which requires establishing an exponential inequality for the variation of the test statistic. Another advantage of using the sparse approximating set is that it allows fast computation in nearly linear time. We present a simulation study that illustrates the superior performance of the penalized scan and of the condensed average likelihood ratio compared with the standard scan statistic.     

Strategies for Multicultural Student Success: What About Grad School?

A workshop was presented to undergraduates as a collection of ethnic minority voices, which provided students an opportunity to participate in an ethnic minority focused event that encouraged mentoring relationships and created opportunities for the sharing of advice between ethnic minority undergraduate and graduate students. The workshop's goals and agenda and implications for counselors are described. The feedback from students was overwhelmingly positive. The authors believe that colleges and universities, and the ethnic minority students who attend them, would benefit greatly from the formal and structured implementation of a workshop series dedicated to encouraging graduate school as a postbaccalaureate option.     

The Boundary Violations Scale: an empirical measure of intergenerational boundary violations in families

This article reviews the development of a new measure to assess children's perceptions of intergenerational boundary violations in families. The Boundary Violations Scale is a theoretically derived instrument consisting of 12 items. Principal components analysis using data from 119 young adolescents from diverse ethnic backgrounds (i.e., 56% Hispanic and 44% non-Hispanic) revealed three factors (promoting maturity, forming coalitions, and communicating as peers) that are consistent with the behavioral manifestations of this construct as posited by structural family theory. The validity of the measure was supported by significant correlations with theoretically relevant measures of family processes and child adjustment as reported by children and their mothers.

Book Reviews

Aggregate forecasts using McFadden's conditional logit model of discrete choice harbor the unrealistic implicit assumption of a random-utility distribution that is homogeneous across both alternatives and individuals. This article relaxes that assumption. A choice model is developed that describes the random-utility component as a probability-mixture model. Some numerical results illustrate that the derived model is not constrained by the independence-of-irrelevant-alternatives property. An experimental test of visual perceptions demonstrates the potential superiority of the model.     

Police training course for agents--entry into the profession and also into the distinction between men and women

An exploratory study was conducted about the initial training of the Public Security Police with the aim to understand the role of this initial training in the distinction between the work of men and women in the police force. This study is part of a broader study about the entry of women into typically male professions. After documental analysis and interviews to students, trainers and school board members, it was concluded that women face greater difficulties in the access to the profession. Moreover, female qualities like the capacity to dialogue are devalued. Nevertheless, women represent an important work tool for the police force. The stigma of physical strength was also encountered and identified in the previous study conducted with elements of the police force. This fact leads us to believe that these stereotypes usually associated with women are defended by elements of the institution.
