Parametric link modification of both tails in binary regression

Common binary regression models such as logistic or probit regression have been extended to include parametric link transformation families. These binary regression models with parametric link are designed to avoid possible link misspecification and improve fit in some data sets. One and two parameter link families have been proposed in the literature (for a review see Stukel (1988)). However in real data examples published so far only one parameter link families have found to improve the fit significantly. This paper introduces a two parameter link family involving the modification of both tails of the link. An analysis based on computationally tractable Bayesian inference involving Monte Carlo sampling algorithms is presented extending earlier work of Czado (1992, 1993b). Finally, the usefulness of the two tailed link modification will be demonstrated in an example where single tail modification can be significantly improved upon by using a two tailed modification.     

Application of Stein-type estimation in combining regression estimates from replicated experiments

This paper considers the application of Stein-type estimation procedure for the coefficients in a linear regression model when data are available from replicated experiment. Two families of estimators characterized by a single scalar are proposed and their large sample asymptotic properties are derived. These are utilized for comparing the performances of the two estimators along with the conventional estimator and conditions for the superiority of one estimator over the other are deduced.     

Ropes course training for youth in a rural setting: “At first I thought it was going to be boring ...”

Outdoor structured activities, such as Ropes Challenge Courses, are typically utilized as interventions for youth coming from urban settings. Evaluation of such programs is scanty at best. In this instance, the course experience is used as a prevention tool for high risk youth in a remote, rural setting of high unemployment, alcohol problems, and low income. The authors discuss the effectiveness of this approach, and the intended and unintended consequences for the rural community at large. The evaluation design relies on extensive qualitative methodology as well as quantitative methods to capture the unique nature of this rural project.     

DO SURVEYS OVERSTATE PUBLIC CONCERNS?

Because the item, "How concerned are you about...?" asks respondentsto indicate their level of concern about an issue, some respondentsmay sense it assumes they are concerned or should be concernedabout the issue. Using a filter question to first determineif people are concerned about the issue before asking for theirdegree of concern may help solve this problem. To test thishypothesis, a split-ballot experiment was embedded in a nationalrandom digit dialing telephone survey on food-related issues.For the four items included in the experiment, the group receivingthe filter versions of the questions gave roughly double thepercentages of "not concerned" responses as the group receivingstandard items, and the filter group also gave fewer responsesat the upper end of the response scale.     

DO RESPONDENTS REALLY "MARK ALL THAT APPLY" ON SELF-ADMINISTERED QUESTIONS?

An experiment was conducted to assess the effect of using "markall that apply" question instructions on survey reporting aspart of the field test for the Second Follow-up of the NationalEducation Longitudinal Study of 1988 Eighth Graders (NELS:88).Mark-all-that-apply instructions were compared with instructionsasking respondents to indicate "yes" or "no" to each responseoption on responses to three items dispersed throughout thequestionnaire and consisting of different topics and numbersof response options. For the three items, significantly fewerresponse options were selected with the mark-all-that-applyinstructions than with the yes/no instructions, but becauseexternal validity criteria were not available, overreportingto the yes/no instructions cannot be ruled out. Instructiondependentprimacy effects, predicted under the hypothesis that respondentswould engage in more superficial processing when given the mark-all-that-applyinstructions, were not found.     

Freud's “Anna O.”: Social work's Bertha Pappenheim

The story of Anna O. has loomed large in psychoanalytic history, but few social workers know that the young woman, who was so influential in the development of Freud's thinking, became a pioneer social worker in Germany. The story of the transformation of the troubled young woman, who was actually Joseph Breuer's patient, is the focus of this paper. In addition, some of the facts of the case are discussed as social constructions. Anna O./ Bertha Pappenheim participated in the creation of the talking cure and eventually went on to be a leading feminist, developer of social programs for women, and social reformer.     

Political theater and student organizations in the 1989 Chinese movement: A multivariate analysis of Tiananmen

Social movement research has often been divided between organizational and cultural analyses of collective action. Organizationally oriented theorists have viewed indigenous organizational structure as the critical variable in the emergence of collective action. Political culture and cultural frame theorists have focused instead on the cultural frames that resonate with audiences, mobilizing them to action. But social movements cannot be the result of one or the other of these factors. An analysis of the 1989 Chinese movement illuminates the multivariate aspects of this social movement. This movement was a two-tiered movement with an organized student leadership tier and a mass audience. Enmeshed in university organizations and student networks, the student leaders relied on an organizational structure that had been emerging since the mid-1980s. This organized leadership tier employed cultural symbols and acts to mobilize mass audiences that were beyond the scope of the students' organizational linkages. The political theater of the organized student leaders was complemented by institutional changes that had been occurring over the decade of reform in China and a political opportunity that allowed wide coverage of the students' activities.     

Gambling and the Law®: Endless fields of dreams

This article examines the current trends of proliferation of commercial gaming, especially in the United States, in the context of the third wave of legalization of gambling that has been experienced since the founding of the nation. The author looks at the historic foundations of the spread of casino-style gambling, and notes the types of casino gaming that have led the way in the current expansion. He also points out why it is reasonable to expect that this wave too may come crashing down, as general acceptance of wide-spread casino gaming in America may indeed be short-lived.Gambling and the Law^® is a registered trademark of I.

Psycho-social impacts of terrorism and organized crime: The counterfinality of the practico-inert

The phrase, the counterfinality of the practico-inert is from Sartre with reference to implications of modern technology as a shorthand for that enormous properly human and anti-natural power of dead human labor stored up in our machinery — an alienated power, which turns back on and against us in unrecognizable forms and can symbolize the massive dystopian horizon of organized crime as well as individual terrorist praxis (Jean-Paul Sartre (1948).Situations II. Paris: Gallimard).     

Zeroing in on leadership effectiveness: The methodological challenges of benchmarking leadership practices

Business success in the 21st century will be based on the widespread mastery of leadership roles, rather than on the directives of a professional or leadership elite. The first step for systematically enacting a leadership development agenda for our nation is to identify the factors, values or qualities most important to leadership effectiveness. Next, we must improve our understanding of how these guiding ideas and insights translate into what successful leaders do. As we perfect this understanding, we will need to operationally define the best practices of successful leaders. These best practices must then become benchmarks for intensive leadership development efforts.This article considers nine methodological challenges of the first agenda item-identification of the factors, values or qualities most important to leadership effectiveness. To illustrate these challenges, the authors use their own business leadership research as a case study. This research surveys 127 chairmen, chief executive officers, and presidents-a cross section of successful U.S.A. business leaders, including men and women from all parts of the nation who have diverse industry, racial, ethnic and religious backgrounds. The authors identify where methodological improvements are needed to cope with the challenges of leadership research. They suggest important directions for methodological development and propose three minimum standards for future leadership research.
