Die Eliminationsmethode – Förderung kreativer Ideen durch die Elimination bekannter Lösungen

This pilot study presents the first implementation and evaluation of a new technique to raise creative performances by eliminating common ideas and conventional solutions in a first step and subsequently generate new ideas. This technique is termed “elimination method”. The experiment of this study was conducted with individually working subjects, not involving group interaction. 30 subjects worked on a creativity task with the elimination method, 30 subjects worked on the same creativity task with brainstorming technique instructions. They produced 1919 ideas which could be summarized to 268 different cognitive elements as the baseline of the research. The theoretical focus of this study is to highlight the role of common knowledge in group discussion and the corresponding intra-individual processes and cognitive processes. Overall results of data examination were in line with expectations and support future testing of the proposed elimination method in a group context. This study was able to show that the instructions for the elimination method induced effects as intended, producing mainly common ideas in the first step and mainly new ideas in the second step, overall resembling the output of the brainstorming condition. The second step of the elimination method outperformed the brainstorming condition in producing idea output with a higher creative density and one-tailed differences were significant (p? =? 0.028). Furthermore, interactions between method and creativity measures were explored. Findings were connected to corresponding research where appropriate and implications for future research were remarked upon.     

Beyond “subjectivity”: The use of the self in social science

Insights about the observer's self can prove useful for understanding others who are the subjects of sociological inquiry. This organizational sociologist studied a midwestern lesbian community using participant observation and in depth interviewing. Subsequent problems with preparing the findings led to development of an analytic technique for dealing with the data. The argument here is that we have much to learn from close examination of the interrelationship between observer and observed.For their help in the preparation of this article, the author would like to thank Estelle Freedman, Marythelma Brainard, Nancy Chodorow, Meredith Gould, and Ann Swidler.     

Concepts and measures for skewness with data-analytic implications

The decomposition of the distribution function into skewness and spread functions serves as a basis for conceptualizing the skewness of a random variable. Measures of skewness are also described in terms of the skewness and spread functions, thereby unifying the measures with the concepts. Results that relate these measures to whether one random variable is more skewed than another are reviewed and extended. Graphical displays are presented for uncovering the nature of the skewness of a variable. The measures are also linked to the issue of symmetrizing a variable.     

Subset Selection Toward Optimizing the Best Performance at a Second Stage

In the search for the best of n candidates, two-stage procedures of the following type are in common use. In a first stage, weak candidates are removed, and the subset of promising candidates is then further examined. At a second stage, the best of the candidates in the subset is selected. In this article, optimization is not aimed at the parameter with largest value but rather at the best performance of the selected candidates at Stage 2. Under a normal model, a new procedure based on posterior percentiles is derived using a Bayes approach, where nonsymmetric normal (proper and improper) priors are applied. Comparisons are made with two other procedures frequently used in selection decisions. The three procedures and their performances are illustrated with data from a recent recruitment process at a Midwestern university.     

Comorbidity of Alcohol and Gambling Problems in Emerging Adults: A Bifactor Model Conceptualization

Addictive disorders, such as pathological gambling and alcohol use disorders, frequently co-occur at greater than chance levels. Substantive questions stem from this comorbidity regarding the extent to which shared variance between gambling and alcohol use reflects a psychological core of addictive tendencies, and whether this differs as a function of gender. The aims of this study were to differentiate both common and unique variance in alcohol and gambling problems in a bifactor model, examine measurement invariance of this model by gender, and identify substantive correlates of the final bifactor model. Undergraduates (N = 4475) from a large northwestern university completed an online screening questionnaire which included demographics, quantity of money lost and won when gambling, the South Oaks Gambling Screen, the AUDIT, gambling motives, drinking motives, personality, and the Brief Symptom Inventory. Results suggest that the bifactor model fit the data well in the full sample. Although the data suggest configural invariance across gender, factor loadings could not be constrained to be equal between men and women. As such, general and specific factors were examined separately by gender with a more intensive subsample of females and males (n = 264). Correlations with motivational tendencies, personality traits, and mental health symptoms indicated support for the validity of the bifactor model, as well as gender-specific patterns of association. Results suggest informative distinctions between shared and unique attributes related to problematic drinking and gambling.     

Ageism and Ageist Language Across the Life Span: Intimate Relationships and Non-intimate Interactions

The possible effects of ageist language and ageism on the structure and function of intimate and non-intimate relationships have received significant attention from social scientists. Recent research grounded in communication accommodation theory ( Giles, Mulac, Bradac, & Johnson, 1987 ), the communication predicament model of ageing ( Ryan, Giles, Bartolucci, & Henwood, 1986 ), the communication enhancement model of ageing ( Ryan, Meredith, MacLean, & Orange, 1995 ), and ageing and stereotype research by Hummert (1994) and colleagues ( Hummert & Mazloff, 2001 ; Hummert, Shaner, & Garstka, 1995 ) point toward the numerous consequences of both negative and positive attitudes toward ageing. Focusing specifically on health care settings, this article reviews recent theoretical positions and empirical findings that link ageist language and ageism to these positive and negative social consequences, and offers pragmatic suggestions and directions for future research .     

Communities in Question: Sociality and Solidarity in Nancy and Blanchot

In his early essays “Violence and Metaphysics” and “The Ends of Man”, Jacques Derrida evoked a “community of the question” when he called for a fundamental questioning of the being of the “we” in the West. This demand was later formulated by Jean‐Luc Nancy and Philippe Lacoue‐Labarthe as the philosophical interrogation of the political (le politique), in distinction from the question of politics (la politique). This essay begins by arguing that what is at stake in this distinction is the very possibility of politics that is otherwise foreclosed. It then explores Nancy’s interrogation of le politique in The Inoperative Community, and compares his response to Maurice Blanchot’s response in The Unavowable Community. It is argued that both deconstructions of “community” depict a certain sociality that corresponds to Derrida’s call—a “communality” beyond or radically other than the traditional model of community as formed by sovereign individuals and as forming the sovereign state. Where they differ is that Blanchot founds the ethical relation of the “unavowable” community on the radical interruption of ontology signaled by death, whereas Nancy casts ontology itself in an ethical register, and thereby allows a certain solidarity to emerge as well.

At the very moment when there is no longer a “command post” from which a “socialist vision” could put forward a subject of history or politics, or, in an even broader sense, when there is no longer a “city” or “society” out of which a regulative figure could be modeled, at this moment being‐many, shielded from all intuition, from all representation or imagination, presents itself with all the acuity of its question, with all the sovereignty of its demand (Jean‐Luc Nancy 2000 Nancy, Jean‐Luc. 2000. Being Singular Plural, Edited by: Robert, Richardson and Anne, O’Byrne. Stanford [1996]: Stanford University Press.  [Google Scholar], p. 43).     

Effect of Level of Disaggregation on Conjoint Cross Validations: Some Comparative Findings*

Early formulations of conjoint models focused on part-worth estimation at the individual level. As the methodology's popularity grew so did industry demands for increasingly larger numbers of attributes and levels. In response to these demands, new approaches, based on partial or full data aggregation (such as clusterwise/latent class conjoint and choice-based conjoint), have appeared. This paper suggests that pooled-data models will often be successful in predicting market shares when researchers employ monotonic attributes. In these cases more of a good attribute (or less of a bad attribute) is always more preferred. In the more realistic case, in which some of the attributes may be nonmonotonic, we find that data aggregation does not predict holdout sample preferences as well as individual part-worth models.     

Predicting Human Papillomavirus Vaccine Intentions of College-Aged Males: An Examination of Parents’ and Son's Perceptions

Abstract

Objective: To examine male students’ and their parents’ human papillomavirus (HPV) vaccine communication in relation to males’ willingness to discuss the vaccine with their health care provider and the likelihood of being vaccinated. Participants: Dyads (n = 111) of students and parents. Methods: Participants completed a HPV vaccine survey based on the risk perception attitude framework in 2009. Results: Male students’ perceived susceptibility for HPV and self-efficacy to talk to their provider were directly related to their intention to discuss the HPV vaccine, and their intention was directly related to their likelihood of being vaccinated. Parents’ perceived self-efficacy to talk to their son and response efficacy of the vaccine were directly related to their intention to talk to their son; however, parents’ intention was not related to the likelihood of their son being vaccinated. Conclusions: College males may benefit from HPV vaccine educational programs that include communication skills training to discuss the HPV vaccine with their parents.
