Local response to planning mandates. The prevalence and utilization of needs assessment by human service agencies.

Federal and state needs assessment mandates have traditionally been criticized both by their originators and by the local human service agencies that are required to conduct these studies as part of the planning process. This paper presents some preliminary evidence that local opposition to assessment may be shrinking as agencies gain a new appreciation for the varied uses of assessment information. Using data from a sample of Wisconsin agencies the prevalence of assessments between 1979 and 1980 is described and the conditions surrounding the practice of needs assessment are outlined. Particular attention is given to factors that affect the utilization of needs assessment results, including the characteristics of the sponsoring agency, the attributes of the study, and the structure of the assessment process.     

A Psychometric Analysis of Field Evaluation Instruments Designed to Measure Students’ Generalist-Level Social Work Competencies

ABSTRACT

There is a dearth of research on the evaluation of the psychometric performance of instruments designed to measure students’ generalist-level social work competencies. There is also uncertainty on the performance of various response option formats used to measure students’ competencies in assessment instruments. Using a sample of 198 master of social work students and 198 field instructors, the current study employs confirmatory factor analysis to assess the psychometric performance of a field evaluation instrument designed to measure students’ generalist-level social work competencies. The results provide evidence to support the validity and reliability of the instrument. The results also highlight nuances associated with a 5-point response option format for items used to measure competency indicators. Implications, limitations, and directions for future research are discussed.     

Post-finasteride syndrome – does it really exist?

Abstract

Inhibitors of 5α-steroid reductase are drugs used to treat androgen-dependent conditions including prostate diseases and androgenic alopecia. Finasteride was the first on the market and is currently the most widely used inhibitor. Dutasteride was the second inhibitor to be approved and has a similar safety profile. Common adverse events of treatment consist of sexual disorders and a negative affect balance. It was described that the prolonged use of 5α-steroid reductase inhibitors in patients with alopecia can cause persistent side effects called a post-finasteride syndrome (PFS), that is not just a simple coexistence of events, but rather a definite syndrome with an iatrogenic background. PFS occurs in susceptible individuals even after small doses of the drug and can last for a long time after the discontinuation of treatment. A deterioration in the quality of life in affected individuals does not justify use of the drug. Wider recognition of PFS symptoms, its incidence, course, prevention, and treatment possibilities will allow the indications for drug use to be reconsidered and treatment to be more personalized. Knowledge about PFS will also help to provide the best treatment for affected individuals and to properly educate patients before obtaining an informed consent for therapy with 5α-steroid reductase inhibitors.     

Fast On-Line/Off-Line Algorithms for Optimal Reinforcement of a Network and its Connections with Principal Partition

The problem of computing the strength and performing optimal reinforcement for an edge-weighted graph G(V, E, w) is well-studied. In this paper, we present fast (sequential linear time and parallel logarithmic time) on-line algorithms for optimally reinforcing the graph when the reinforcement material is available continuously on-line. These are the first on-line algorithms for this problem. We invest O(|V|³|E|log|V|) time (equivalent to (|V|) invocations of the fastest known algorithms for optimal reinforcement) in preprocessing the graph before the start of our algorithms. It is shown that the output of our on-line algorithms is as good as that of the off-line algorithms. Thus our algorithms are better than the fastest off-line algorithms in situations when a sequence of more than (|V|) reinforcement problems need to be solved. The key idea is to make use of ideas underlying the theory of Principal Partition of a Graph. Our ideas are easily generalized to the general setting of polymatroid functions. We also present a new efficient algorithm for computation of the Principal Sequence of a graph.     

Optimal Planning Quantities for Product Transition

The replacement of an existing product with a new one presents many challenges. In particular, uncertainties in a new product introduction often lead to extreme cases of demand and supply mismatches. This paper addresses inventory planning decisions for product upgrades when there is no replenishment opportunity during the transition period. We allow product substitution: when a company runs out of the old product, a customer may be offered the new product as a substitute. We show that the optimal substitution decision is a time‐varying threshold policy and establish the optimal planning policy. Further, we determine the optimal delay in a new product introduction, given the initial inventory of the old product.     

Codes of ethics and firm size: A stakeholder approach to strategic planning

A firm's capital budgeting and strategic planning decisions have the potential to affect many groups of people called stakeholders. A stakeholder is any group or individual who can affect or is affected by the achievement of the firm's objectives. This study examines whether the presence of a code of ethics that specifically addresses capital budgeting/strategic planning decisions will significantly raise the awareness of social responsibility during the long-run planning process. This study also examines whether firm size is associated with the awareness of social responsibility during the long-run planning process. Support was found that a code of ethics that addresses long-range planning is associated with higher awareness during the planning process. Firm size was not found to be statistically different.     

An Evaluation of Capacity Sensitive Order Review and Release Procedures in Job Shops

We investigate the performance of capacity-sensitive order review and release (ORR) procedures in job shop environments that have not been previously explored. Previous research has ignored the case of job shops which must perform to very tight due-dates because of time-sensitive customers. We propose and test a new capacity sensitive ORR procedure called path based bottleneck (PBB) in such environments, along with the modified infinite loading (MIL) procedure which has been shown to work well in several studies. We compare the performance of these two controlled release rules with that of immediate release rule under different conditions of capacity utilization and customer specified exogenous duedates. Our results indicate that PBB performs well in lowering total costs when due-dates are tight, while MIL is a better procedure with relatively loose to medium due-dates. We also show that in many cases, the shortest processing time (SPT) dispatching rule is a superior performer than a due-date based rule like critical ratio (CR); a conclusion which is contrary to the existing research in this area. In addition, the shop floor control policies recommended are shown to be sensitive to the cost structure of the firm. The managerial implications of this research in providing effective shop floor control in job shops operating under tight due-date conditions are also discussed.
