A productivity study in a chemical plant

This paper describes a case study in the application of a productivity analysis model in a plant producing industrial gases. Although the process is a relatively simple one, several inputs (labour, electricity, capital and some materials) and several outputs (liquid and gaseous oxygen, gaseous nitrogen, argon and a hydrogen-nitrogen mixture) are involved. The case study demonstrates how measures of total input and total output can be applied and analyses the performance of the plant over a 15-month period in terms of a variety of managerial control ratios.     

"Conflict management" and "conflict resolution" are not synonymous terms

Robbins sees functional conflict as an absolute necessity within organizations and explicitly encourages it. He explains: "Survival can result only when an organization is able to adapt to constant changes in the environment. Adaption is possible only through change, and change is stimulated by conflict." Robbins cites evidence indicating that conflict can be related to increased productivity and that critical thinking encourages well-developed decisions. He admits, however, that not all conflicts are good for the organization. Their functional or dysfunctional nature is determined by the impact of the conflict on the objectives of the organization. The author identifies several factors underlying the need for conflict stimulation: (1) managers who are surrounded by "yes men"; (2) subordinates who are afraid to admit ignorance or uncertainty; (3) decision-makers' excessive concern about hurting the feelings of others; or (4) an environment where new ideas are slow in coming forth. He suggests techniques for stimulating conflict; manipulating the communication channels (i.e., repression of information); changing the organizational structure (i.e., changes in size or position); and altering personal behavior factors (i.e., role incongruence). Robbins stresses that the actual method to be used in either resolving or stimulating conflict must be appropriate to the situation.     

The need for revaluation and assessment of Australian foster care programmes

This is a brief report on one aspect of a programme of applied research, in a large social welfare agency, designed to provide a basis for the evaluation of the policies, activities and structure of the agency.     

Daubert v. Merrell Dow pharmaceuticals: Toward a better relationship between law and science

[Scientists] are neither Gods nor charlatans; they are merely experts, like every other expert on the political stage. They have, of course, their special area of expertise, the physical world, but their knowledge is no more immaculate than that of economists, health policy makers, police officers, legal advocates, weather forecasters, travel agents, car mechanics, or plumbers. The expertise that we need to deal with them is the well‐developed expertise of everyday life; it is what we use when we deal with plumbers and the rest. Plumbers are not perfect-far from it‐but society is not beset with anti‐plumbers because being anti-plumbing is not a choice available to us.1     

College Students' Attitudes Toward Religion

Data on Russian students show that there is a large gap between declaring oneself a believer or identifying oneself with a religion and actually participating in it. Students are in favor of keeping religion and politics separate, and so in general show very weak support for recent statements about making Russian Orthodoxy the new state religion.     

Volunteerism and Social Work Educators: Findings from a National Survey

Abstract

This study reports the results of a national survey designed to identify the nature and levels of volunteer work that social work educators contribute to the social welfare sector. Findings reveal that nearly all social work educators engage in formal volunteer work and perform a variety of roles in human service agencies. The most common volunteer activities are advocacy, administration and consultation. The least common volunteer activities are evaluation, data management and emergency services. Study results also indicate that tenure status and primary teaching area are positively associated with the amount and type of volunteer work performed.     

Continuous outcomes stochastically mismeasured as discrete random variables: a maximum likelihood approach

In an economic model of retirement behavior, a continuous dependent variable was required; the variable could only be estimated discretely with error, however. Parameter estimates using this dependent variable and ordinary least squares regression are inefficient. In th is paper, we develop a maximum likelihood procedure which adjusts for this heteroscedasticity.     

Engaging Intercollegiate Athletes in Preventing and Intervening in Sexual and Intimate Partner Violence

Abstract

Objective: The object of this exploratory evaluation was to evaluate the “Bringing in the Bystander” sexual and intimate partner violence prevention program with a new sample of intercollegiate athletes. Participants and Methods: Fifty-three male and female athletes participated in the program (experimental group), and 86 were in the control group. All completed pretest, posttest, and 2-month follow-up surveys, including assessment of rape myth acceptance, intent to engage in bystander behaviors, bystander confidence, and bystander behaviors. Results: The program worked overall and for both women and men, improved bystander confidence and intent to engage in bystander behaviors, and did not create significant backlash effects (ie, worsening of attitudes as a result of program). Conclusions: The program fits with the intent of the National Collegiate Athletic Association CHAMPS/Life Skills program regarding its focus on the overall development of student-athletes and demonstrates the promising bystander approach compatible with the 2007 American College Health Association toolkit, Shifting the Paradigm: Primary Prevention of Sexual Violence.     

Incorporating Content on Offenders and Corrections into Social Work Curricula

This article presents suggestions for incorporating content on adult offenders and corrections across diverse curriculum areas, including human behavior in the social environment, practice, research, and social welfare policy. Social work educators are provided with guiding principles for work with offenders and with many concrete strategies for integrating material on this often forgotten population into already existing courses.     

An emplrical bayes approach in estimating the parameters of the or more geometric distributions

The estimation of the parameters of two or more geometric distribuionsis considered by usinq an empirical Bayesian approach. Robbins (1983) gave empirical Bayes estimates if the number of distributions N is large, buthere we consider the cascwhore N is small. The parameters of the prior distribution areest imated by looking at maximum like lihood and momentest imation methods.
