Probability density function of quotient of order statistics from the pareto,power and weibull distributions

This paper deals with the probability density functions of quotient of order statistics. We use the Mellin transform technique, to find the distribution of the quotient Z= X/Xwhere X.,X(i < j) are the ith and jth order statistics from the Pareto, Power and Weibull distributions     

Research newsnotes

The authors describe the curricular changes made as part of a 20-year commitment by Smith College School for Social Work (SCSSW), a graduate school with a clinical social work specialization, to become an antiracism institution. Unaware of precedents, faculty, administration, and students needed to develop structures and processes to confront inherent institutional racism at the SCSSW. In addition to multiple administrative actions, every aspect of the curriculum was reevaluated, leading to changes in courses offered and everything about them, from syllabi to pedagogy, as well as how faculty are trained and supported. The authors found that explicit and implicit curriculum must work together in intentional and synchronous ways. Critical intention across design, implementation, evaluation, accountability, and openness to process is emphasized here. They conclude that an antiracism commitment requires continuous engagement, connection, challenge, learning, and teaching and a curriculum that is fluid, flexible, proactive, and responsive.     

Extracting a revised labor supply theory from Becker's model of the household

Conflicting assumptions about labor supply behavior lie at the nexus of ideological and theoretical debates regarding the reality of involuntary unemployment, the efficacy of Keynesian macro-policy, and the appropriate nature of welfare policy. This can in part be attributed to the fact that orthodox theory is effectively predicated upon describing the behavior of individuals whose level of affluence enables them to voluntarily withhold their labor from the market. Ironically, a means of resolution appears if we extend Gary Becker's utility producing model of the household to recognize two latent behavioral concerns: (1) the ‘need’ of households for money income in order to produce utility, and (2) the presence of work activity in the home. The resulting generalized labor supply model extends Becker's analysis to explicitly encompass both the behavior of the affluent, and the behavior of the poor who need to work in order to sustain their existence.     

Competency-Based Training: Objective Structured Clinical Exercises (OSCE) in Marriage and Family Therapy

The field of marriage and family therapy (MFT) has recently engaged in the process of defining core competencies for the profession. Many MFT training programs are adapting their curriculum to develop more competency-based training strategies. The Objective Structured Clinical Examination (OSCE) is widely used in the medical profession to assess clinical competence. These examinations involve using simulated clinical situations as a tool in conducting summative evaluations of trainee competence. This article describes an adaptation of the OSCE procedures for competency-based training of MFT students. Instead of using the procedures as a summative examination as is typical in medical education, this article proposes how to use them as formative exercises in the development of student competence. The development of the OSCE is discussed, including “blueprinting,” focused competencies, procedures, and feedback protocols. The article concludes with suggestions of how to continue the development of the OSCE for evaluation in MFT education.     

Robust methods in econometrics

This survey of recent developments in robust estimation and inference is directed primarily toward econometricians. It is argued that many of the techniques in common use in econometrics are highly sensitive to unverified hypotheses. Recent progress in designing alternative robust procedures is described and some prospects for future developments are discussed.
