Daily Versus Major Life Events as Predictors of Symptom Frequency: A Replication Study

Predictions of physical symptomatology by daily life events and by major life events were compared, replicating and expanding work reported by De-Longis, Coyne, Dakof, Folkman, & Lazarus (1982). Analyses of daily, prospective data collected on 79 married men for 90 days demonstrated that daily, undesirable events were better predictors of symptom frequencies than either past, major life events or daily, desirable events. These results, similar to those found by DeLongis et al. (1982), were further explored by examining “healthy” subjects versus subjects with prior medical conditions. Undesirable daily events were a much stronger predictor of physical symptoms in the healthy group than in the prior medical conditions group.     

MMPI–2 Characteristics of Transsexuals Requesting Sex Reassignment: Comparison of Patients in Prehormonal and Presurgical Phases

Forty-three medical students and 78 nursing students each filled out four copies of the Interpersonal Check List. The subjects described self, ideal self as physician or nurse, and typical and ideal work partner. For each questionnaire the two summary scores Dom and Lov were computed. The results indicate a discrepancy between concepts of self and ideal self and the results also point to considerable disagreement between medical students and nursing students about their roles on the physician-nurse team.     

A Cautious Note on Auxiliary Variables That Can Increase Bias in Missing Data Problems

The treatment of missing data in the social sciences has changed tremendously during the last decade. Modern missing data techniques such as multiple imputation and full-information maximum likelihood are used much more frequently. These methods assume that data are missing at random. One very common approach to increase the likelihood that missing at random is achieved consists of including many covariates as so-called auxiliary variables. These variables are either included based on data considerations or in an inclusive fashion; that is, taking all available auxiliary variables. In this article, we point out that there are some instances in which auxiliary variables exhibit the surprising property of increasing bias in missing data problems. In a series of focused simulation studies, we highlight some situations in which this type of biasing behavior can occur. We briefly discuss possible ways how one can avoid selecting bias-inducing covariates as auxiliary variables.     

the media's portrayal of urban and rural school violence: a preliminary analysis

Although the juvenile arrest rate has declined in the last few years, public awareness of juvenile crime has not diminished (Snyder 1996; Schiraldi 1998). The recent rash of rural school shootings has, in fact, heightened public awareness of juvenile crime and delinquent behavior. This research examines acts of school violence that have been committed by juveniles in three rural school districts and analyzes how the newspaper media present these acts relative to similar acts committed by juveniles in urban school settings. Our content analysis of the Wall Street Journal, Louisville Courier Journal, New York Times, St. Louis Post Dispatch, Los Angeles Times, and Washington Post reveals that these newspapers present school violence in these two settings very differently and that these differences are reflected in the way the political system reacts to such incidents.     

Attitudes toward women's right to self-determination

Abstract

After briefly describing the purpose, structure, and functions of a typical family planning center, the paper suggests and gives support for a more relationship-centered service delivery system. The major thesis of the paper is that these centers should adopt a system which recognizes and promotes intimate human relationships, and that marriage and family counselors would be highly valuable resources in such a system. The paper stresses the importance of attending to the myriad relationship issues involved in the entire process of enabling individual couples to more effectively plan and control their own fertility. Several ways in which the marriage and family counselor can work with and within the family planning center are outlined.     

Aptitude and Trait Predictors of Manned and Unmanned Aircraft Pilot Job Performance

Sixty-seven United States Navy maintainers (55 men and 12 women) representing both the aviation and surface communities participated in an experiment examining the efficacy of a simulation to assist technicians in rapidly understanding a system's state. Participants were assigned to one of three groups based on the technicians' experience and one of two experimental conditions: simulation (SIM) or technical manual (TM). The experimental task consisted of a series of eight questions regarding the condition of the S-3 aircraft's nose wheel steering (NWS) system given a set of initial aircraft conditions. To aid in performance of the experimental task, participants assigned to the TM condition were given a paper copy of the S-3 aircraft's organizational maintenance manual for the NWS system, and participants assigned to the SIM condition were given a laptop computer running a computer-based interactive model of the S-3 NWS system. Results showed that regardless of level of expertise, participants assigned to the SIM condition answered questions significantly faster than participants assigned to the TM condition. Further, technicians experienced in nonaviation maintenance assigned to the SIM condition answered questions significantly more accurately than experienced nonaviation technicians assigned to the TM condition.     

Measuring adaptability demands of jobs and the adaptability of military and civilians

Jobs within the military and in civil society differ in character and requirements. It is assumed that differences in job types both within civil and military domains require different dimensions of adaptability competency. The present study investigates this assumption. The Dutch Adaptability Dimensions And Performance Test (D-ADAPT) was used to measure both the adaptability demands of jobs, and of self-assessed adaptability competency of employees. In addition, the predictive value of certain personality traits (openness, neuroticism, and conscientiousness) and other relevant personal characteristics (cognitive flexibility, learning goal orientation) on various adaptability dimensions was explored. Military personnel were found to estimate their adaptability competency as higher than civilians did. With respect to the civilian jobs, the adaptability demands varied across job types. This was not found in the set of military jobs, possibly due to a smaller variety of jobs included. This study also shows that a variety of personal characteristics predict different dimensions of adaptability. Cognitive flexibility was found to be the best predictor for adaptability in general. Openness turned out to be a good predictor within the civilian group, whereas neuroticism was a better predictor within the military group. Results of this study contribute to a better understanding of work adaptability and influencing personality characteristics. Practical implications for selection and training of personnel can be derived, based on the acquisition of adaptability competency that matches the type of job.     

Understanding dieting: A social cognitive analysis of hedonic processes in self-regulation

The present paper introduces a novel approach to understanding failures of self-regulation in chronic dieters. Traditional approaches to this problem have focused on consciously controlled processes of eating regulation, such as the realisation that one has overeaten, or the experience of food cravings. We argue, however, that dieters' problem might rather lie in their sensitivity to the hedonic aspects of food and the resulting inhibition of their dieting goal. We present a goal-conflict model that integrates recent findings on hedonic sensitivity in eating regulation with social cognition research on nonconscious goal pursuit. We show that the perception of attractive food triggers hedonic thoughts about food in chronic dieters and leads to the inhibition of their dieting goal. These processes make subsequent overeating more likely, while bypassing dieters' conscious awareness. We discuss how our model can accommodate earlier research findings in this area, and we consider its implications for dieting behaviour and for our attempts to resist temptations more generally.     

Self-Portraits: Possible Selves in European-American,Chilean, Japanese and Japanese-American Cultural Contexts

Possible selves of students from European-American (EA), Chilean (CH), Japanese-American (JA), and Japanese (JN) cultural contexts were analyzed, revealing differences in the emphasis given to various content themes. EA possible selves focus on intrapersonal themes (i.e., “fear being dependent”), consistent with cultural emphases on uniqueness and independent development. In JN, JA and CH contexts, career and education themes dominate possible selves, consistent with particularly strong cultural emphasis on professional and academic accomplishments. The cultural contexts also differ in their predominant configurations of possible selves—EA and CH possible selves often show balance (expected and feared selves of similar theme but opposing valence, i.e., “expect to graduate from college” and “fear dropping out of college”) while JN and JA selves more frequently match (expected and feared selves of similar thematic content and valence, i.e., “expect to be idle” and “fear being idle”).     

Perceptual organization and artificial attention for visual landmarks detection

In biological vision systems, attention mechanisms are responsible for selecting the relevant information from the sensed field of view, so that the complete scene can be analyzed using a sequence of rapid eye saccades. In recent years, efforts have been made to imitate such attention behavior in artificial vision systems, because it allows optimizing the computational resources as they can be focused on the processing of a set of selected regions. In the framework of mobile robotics navigation, this work proposes an artificial model where attention is deployed at the level of objects (visual landmarks) and where new processes for estimating bottom-up and top-down (target-based) saliency maps are employed. Bottom-up attention is implemented through a hierarchical process, whose final result is the perceptual grouping of the image content. The hierarchical grouping is applied using a Combinatorial Pyramid that represents each level of the hierarchy by a combinatorial map. The process takes into account both image regions (faces in the map) and edges (arcs in the map). Top-down attention searches for previously detected landmarks, enabling their re-detection when the robot presumes that it is revisiting a known location. Landmarks are described by a combinatorial submap; thus, this search is conducted through an error-tolerant submap isomorphism procedure.
