Trait social anxiety and physiological activation: cardiovascular threat during social interaction

Physiological activation is thought to be a part of the constellation of responses that accompany social anxiety, but evidence regarding the nature of such activation is mixed. In two studies, the relationship between trait social anxiety and responses during social interaction was explored using on-line cardiovascular indexes of threat. Across Studies 1 and 2, women higher in trait social anxiety exhibited cardiovascular responses consistent with greater threat during the social interaction than those lower in social anxiety. Retrospective self-reports (Studies 1 and 2), as well as partner ratings and interaction behavior (Study 2), also revealed consistent differences as a function of trait social anxiety. Study 2 added male participants, among whom a divergence emerged between results for physiological measures and other responses. These findings have implications for understanding physiological as well as psychological processes among people with social anxiety during social interaction.     

Recruiters' Assessment and Use of Social Capital in Résumé Screening1

An experiment was conducted with undergraduate business students to investigate how human resource (HR) recruiters use social capital conceptualized as friendship between applicants and the recruiter in screening résumés. Results showed that social capital influenced recruiters' assessment of applicants above and beyond human capital. In addition, the influence of friendship ties in applicant assessment was more prominent among female HR recruiters than among male recruiters. Implications for researchers and practitioners are discussed in the context of employee selection.     

Rewarding Good Citizens: The Relationship Between Citizenship Behavior,Gender, and Organizational Rewards1

The relationship between organizational citizenship behavior (OCB) and two organizational rewards—salary and promotion—was examined. Employee gender also was tested as a moderator. Data from 440 individuals employed in multiple settings indicated that individuals who reported engaging more frequently in OCB directed toward the organization (OCBO) also reported receiving more promotions. Further, results indicated that gender was a moderator such that the relationship between OCBO and promotion was stronger for males than for females. The results also revealed an interaction between OCB directed toward individuals (OCBI) and OCBO. Specifically, high OCBI and low OCBO related to lower promotion rates than did low OCBI and low OCBO. Results are discussed in terms of implications for individual career development.     

Reduction and emergence in the physical sciences: Reply to Rueger

I analyse Rueger’s application of Kim’s model of functional reduction to the relation between the thermal conductivities of metal bars at macroscopic and atomic scales. 1) I show that it is a misunderstanding to accuse the functional reduction model of not accounting for the fact that there are causal powers at the micro-level which have no equivalent at the macro-level. The model not only allows but requires that the causal powers by virtue of which a functional predicate is defined, are only a subset of the causal powers of the properties filling the functional specification. 2) The fact that the micro-equation does not converge to the macro-equation in general but only under the constraint of a “solvability condition” does not show that reduction is impossible, as Rueger claims, but only that reduction requires inter-level constraints. 3) Rueger tries to analyse inter-level reduction with the conceptual means of intra-level reduction. This threatens the coherence of his analysis, given that it makes no sense to ascribe macroproperties such as thermal conductivity to entities at the atomic level. Ignoring the distinction between theses two senses of “reduction” is especially confusing because they have opposite directions: in intra-level reduction, the more detailed account reduces to the less detailed one, whereas in inter-level reduction, the less detailed theory is reduced to the more detailed one. 4) Finally I criticize Rueger’s way of using Wimsatt’s criteria for emergence in terms of non-aggregativity, to construct a concept of synchronic emergence. It is wrong to require, over and above non-aggregativity, irreducibility as a criterion for emergence.     

Making Sense of the Barriers Women Face in the Information Technology Work Force: Standpoint Theory, Self-disclosure, and Causal Maps

Two theoretical perspectives (i.e., standpoint theory and the communication boundary management theory) were used to investigate the comments that 39 female information technology (IT) employees made during focus groups as they discussed issues related to workplace barriers and voluntary turnover. The revealed causal mapping method was used to analyze the women’s responses. Voluntary turnover decisions were influenced by work schedule flexibility, family responsibilities, work stress, job qualities, and lack of consistency in workplace policies. Perceived barriers to promotion were linked to lack of respect, ageism, stress, and work schedule flexibility. Differences emerged between explicitly stated and implicitly embedded responses. Women explicitly discussed issues consistent with previous IT research; however their implicit statements often addressed barriers not commonly linked with IT advancement and turnover concerns.     

Innovations in computational type theory using Nuprl

For twenty years the Nuprl (“new pearl”) system has been used to develop software systems and formal theories of computational mathematics. It has also been used to explore and implement computational type theory (CTT)—a formal theory of computation closely related to Martin-Löf's intuitionistic type theory (ITT) and to the calculus of inductive constructions (CIC) implemented in the Coq prover.

This article focuses on the theory and practice underpinning our use of Nuprl for much of the last decade. We discuss innovative elements of type theory, including new type constructors such as unions and dependent intersections, our theory of classes, and our theory of event structures.

We also discuss the innovative architecture of Nuprl as a distributed system and as a transactional database of formal mathematics using the notion of abstract object identifiers. The database has led to an independent project called the Formal Digital Library, FDL, now used as a repository for Nuprl results as well as selected results from HOL, MetaPRL, and PVS. We discuss Howe's set theoretic semantics that is used to relate such disparate theories and systems as those represented by these provers.     

Spirituality and transformation in a community-based group in the Bahamas

Understanding the specific contexts where spirituality may or may not be helpful has been identified as a priority in spirituality and health research. The study aims were to clarify the helpfulness of spirituality and the interrelationships among transformation, spirituality, and forgiveness in this community-based group offered in a societal context of violence. Sixteen group participants from the Bahamas were selected and interviewed. Nine participants were female (56%); 75% identified as Black and 25% identified as White/Caucasian. NVivo 11 software was used. Transformation and spirituality themes were prevalent: themes related to prayer, group connection, and compassion were prominent. Selected spirituality themes were proximal to transformation themes, particularly forgiving others. The group process themes were closely linked to transformation themes. Participants noted that modelling by the group provided support for them to forgive and change. These findings may inform future efforts to intervene in communities experiencing violence and societal fragmentation.     

A Measure of the Stability of Activities in a Family Environment

The Stability of Activities in the Family Environment (SAFE) measure was developed to assess aspects of the construct of family stability. An earlier version of the SAFE was revised to improve its psychometric properties and better elaborate the construct that underlies the measure. College students completed the revised SAFE and other measures of family functioning with respect to their families of origin and measures of current adjustment. Findings support the reliability, internal consistency, and factor structure of the SAFE. It is suggested that the results of the factor analyses and findings that different aspects of family stability demonstrated different patterns of relationships to indices of family functioning, are consistent with the presumption guiding the development of the SAFE that families achieve stability in diverse ways. The validity of the SAFE was further supported by its relationship to measures of current self-esteem and depression.     

The Social Context of Adaptation to Traumatic Events: Soviet Jews and the Holocaust

Much of the literature on trauma focuses on the impact of a single traumatic event and its psychological sequelae on a given individual. Little attention has been paid to the effects of multiple traumatic events within one lifetime, or the importance of understanding the relation of the social context of the trauma(s) to the experience of the trauma survivor. This study presents a qualitative analysis of interviews with older survivors of the Nazi attempt to exterminate the Jews (the Holocaust), who had recently migrated from the former Soviet Union to the United States. In-depth depictions of the effects of multiple traumas on the mental health of single individuals are presented. Further emphasis is placed on the specific social context of trauma to more fully understand the older adult trauma survivor.
