Decentralized planning with an interdependent marketing-production system

An interdependent marketing-production planning model based on control theory is described. The interdependent model is a composition of the Vidale-Wolfe model relating advertising rates to sales rates, and the Holt, Modigliani, Muth & Simon (HMMS) production inventory planning model. An overall optimal marketing-production plan is identified using the interdependent model. This overall optimal plan (resulting from centralized planning) is then used as a reference point to measure the effectiveness of decentralized planning approaches. It is found that in some cases almost no coordination is necessary, in some cases the use of a transfer price leads to good decentralized planning, and in other cases centralized planning must be employed to achieve good results. Several examples are presented to illustrate the cases in which decentralized planning does and does not work well.     

Legal standards for evaluation research: A reply to Smith

Smith (1981), asserting that not all evaluative studies require the same degree of evidence for decision-making, suggests a legal paradigm for determining how much certainty is necessary for informed decision-making. Specifically, he argues for the use of three levels of certainty, i.e., suggestive, preponderant, or conclusive evidence, modeled after the legal standards of proof. Unfortunately, such an approach is untenable for several reasons. Smith's suggestion that decision-makers adopt legal terminology, for example, is really a recommendation of form rather than substance and, furthermore, his analogy from the law to the evaluation context is based upon a misunderstanding of the trial process. These and other problems with Smith's suggestions are discussed.     

A review of the empirical status of tranditional modes of interpersonal helping: Implications for social work practice

The empirical status of traditional modes of interpersonal helping are reviewed in terms of client deterioration, spontaneous remission, and immediate and long-term effects. Necessary therapeutic conditions for client change, such as genuineness, nonpossessive warmth, and accurate empathic understanding, are discussed. Variables contributing to the ineffectiveness of traditional modes of interpersonal helping are elaborated in terms of the following: the medical model of mental disease, behavior as symptoms, diagnosis and treatment, labeling and stigmatization, the training of clinical social workers, conflict models of human behavior, academic achievement and fieldwork practice, criteria for the selection of theories of human behavior and induced change, and the relationship between academic performance and effectiveness in the field of clinical practice. The rationale is presented for a new type of social worker, the behavioral social worker, whose profile is reviewed in terms of knowledge base, behavioral skills, and value base.
