RELATING PROCESS TO OUTCOME IN MARITAL THERAPY

Although there are a growing number of outcome research studies in marital therapy, there is a complete absence of research on change processes, and how such processes relate to outcome. This study attempts to analyze the process of change in the "best" sessions of Emotionally Focused Marital Therapy (EFT) (Greenberg & Johnson, 1986). Client performance in therapy was rated on depth of experiencing and the quality of interpersonal interactions. The occurrence of particular change events arising from the theoretical principles of EFT was also noted. Results confirmed hypotheses that higher levels of experiencing and more autonomous and affiliative interactions characterized "best" sessions of couples who were successful in therapy. The implications for treatment are discussed.     

Managers' Perspectives on Making Major Investment Decisions: the Problem of Linking Strategic and Financial Appraisal

Major investment decisions are an important factor shaping strategic change in complex organisations. Traditionally, they have been primarily regarded as the domain of financial theory, with a few notable exceptions. This paper explores how the apparent gulf between strategic and financial appraisal of major investment decisions can be bridged. The approach taken in this research study was to explore linkages between strategic and financial appraisal from managers' own perspectives. These perspectives were examined through a learning process. This enabled managers to reflect and debate on their experiences and issues - upon both strategic and financial theory(s). Unlike many prior studies, this research took a qualitative approach to data analysis and interpretation. This yielded a range of insights - some of these amplified findings in earlier research studies; others suggested a more radical shift in thinking on strategic/financial appraisal linkages towards a closer fusion of the two disciplines.     

On the Use of “Intent to...” Variables in Organizational Research: An Empirical and Cautionary Assessment

Organizational research often relies onsurrogate variables. By surrogate we donot refer to family of construct, factor, or latentvariables. Rather, we address the situation where onevariable is literally the substitute for another variablethat is generally unavailable. Consider, for example,the use of intent to turnover orintent to transfer variables commonly usedwhen actual turnover or transfer data are unavailable. Wedemonstrate that reliance on such surrogate variablesmay lead to some misinterpretation. This tendency may beparticularly apparent when the relationship between the surrogate and the actual variable is low. Thismay be further exacerbated when the relationship betweenthe surrogate variable and a third variable is modest aswell.     

Radon Risk Information and Voluntary Protection: Evidence from a Natural Experiment

This study examines the perceived risks and mitigating behavior of Maine households who received new information on their exposures to significant health risks from indoor radon. The observed responses of these households illustrate conceptual issues related to designing an effective risk information program. Despite the involvement of generally well-motivated homeowners and well-intentioned researchers and government officials, we conclude that the risk information approach used in Maine failed to induce appropriate, cost-effective voluntary protection. The results indicate that, after receiving radon test results, information on associated health risks, and suggestions on how to reduce exposures: perceived risks tended to understate objective risks by orders of magnitude, and there was no statistically significant relationship between mitigating behavior and objective risks. These results suggest that the formation of risk perceptions and subsequent behavioral adjustments involve complex interactions among information, contextual, socioeconomic, and psychological variables. Therefore, government programs that seek to reduce health and safety risks with information programs, instead of using more conventional enforced standards, must be crafted very carefully to accommodate this complex process.     

Multi-terminal vehicle-dispatch algorithm

This paper introduces the Multi-Terminal Sweep Algorithm, a heuristic algorithm for obtaining an approximate solution to the multiple terminal vehicle-dispatch problem. The procedure determines a set of routes by which vehicles from two or more terminals can service a collection of demand points so that the total distance traveled is kept near to the minimum. This solution also satisfies constraints on the vehicle load and on the length of each route. Application of the algorithm to eleven multiple terminal vehicle-dispatch problems shows that near-optimal solutions to large-scale problems can be found in a reasonable amount of computer time.     

Immigration reform and the browning of America: tensions,conflicts and community instability in metropolitan Los Angeles

"Tensions, conflicts, and community instability associated with heightened immigration--especially of nonwhite immigrant groups--threaten to balkanize America. This article highlights the root causes of the growing opposition to both immigrants and U.S. immigration policy--the nativist backlash, presents a typology of the community-level conflicts that have arisen as a consequence of heightened immigration--legal and illegal--to the United States over the last 30 years, and outlines the conditions under which diversity can be brought to the forefront as one of society's strengths.... The 1992 Los Angeles County Social Survey (LACSS)...provides insights into the nature and magnitude of intergroup stereotyping and prejudice in a community in which large numbers of immigrants have settled."     

Asymptotic properties of Bayes risk for one-sided tests

Consider a given sequence {T_n} of estimators for a real-valued parameter θ. This paper studies asymptotic properties of restricted Bayes tests of the following form: reject H₀:θ ≤ θ₀ in favour of the alternative θ > θ₀ if T_n ≤ C_n, where the critical point C_n is determined to minimize among all tests of this form the expected probability of error with respect to the prior distribution. Such tests may or may not be fully Bayes tests, and so are called T_n-Bayes. Under fairly broad conditions it is shown that and the T_n-Bayes risk where a_n is the order of the standard error of T_n, - is the prior density, and μ is the median of F, the limit distribution of (T_n – θ)/a_nb(θ). Several examples are given.     

Where is the border? Current issues in the diagnosis and treatment of the borderline

Differential diagnosis of subtypes of individuals meeting criteria for borderline personality disorder has received only limited attention in the recent social work literature on the borderline. Whether the borderline disturbance is moderate or severe, the condition may overlap with several borders, suggesting that borderline personality disorders are a heterogeneous group of conditions. Discrimination between different subtypes is necessary in order to help clients obtain the optimum combination of treatments.
