Childhood anxiety sensitivity index factors predict unique variance in DSM-IV anxiety disorder symptoms

Anxiety sensitivity (AS) is an established cognitive risk factor for anxiety disorders. In children and adolescents, AS is usually measured with the Childhood Anxiety Sensitivity Index (CASI). Factor analytic studies suggest that the CASI is comprised of 3 lower-order factors pertaining to Physical, Psychological and Social Concerns. There has been little research on the validity of these lower-order factors. We examined the concurrent and incremental validity of the CASI and its lower-order factors in a non-clinical sample of 349 children and adolescents. CASI scores predicted symptoms of DSM-IV anxiety disorder subtypes as measured by the Spence Children's Anxiety Scale (SCAS) after accounting for variance due to State-Trait Anxiety Inventory scores. CASI Physical Concerns scores incrementally predicted scores on each of the SCAS scales, whereas scores on the Social and Psychological Concerns subscales incrementally predicted scores on conceptually related symptom scales (e.g. CASI Social Concerns scores predicted Social Phobia symptoms). Overall, this study demonstrates that there is added value in measuring AS factors in children and adolescents.     

Religious and National Identity after the Belfast Good Friday Agreement

National and religious identification processes can be seen as the basis of the conflict in Northern Ireland, and over the course of the conflict preferred social and political identities became increasingly oppositional and entrenched. This paper reviews this evidence using population-level studies of self-categorized national and religious identity. In an attempt to explore the bases of these identities, two interrelated qualitative studies examining the constructions of national and religious identification are reported. The findings presented suggest the continuing predominance of national and religious identities that have generally been constructed as opposing. Evidence of complete overlap of the identities is evidenced in conflation of religion and nationality in adolescents' essays. Theoretical sampling of adults living on the border between Northern Ireland, the republic of Ireland, and those in mixed marriages highlight the strategic use of national and religious identities that may act to support divisions in post-Agreement Northern Ireland.     

Location coding by the human visual system: multiple topological adaptations in a case of strabismic amblyopia

Amblyopia, a major cause of vision loss, is a developmental disorder of visual perception commonly associated with strabismus (squint). Although defined by a reduction in visual acuity, severe distortions of perceived visual location are common in strabismic amblyopia. These distortions can help us understand the cortical coding of visual location and its development in normal vision, as well as in amblyopia. The history of retinotopic mapping in the visual cortex highlights the potential impact of amblyopia. Theories of amblyopia include topological disarray of receptors in primary visual cortex, undersampling from the amblyopic eye compared with normal eyes, and the presence of anomalous retinal correspondence or multiple cortical representations of the strabismic fovea. We examined the distortions in a strabismic amblyope, using a pop-out localization task, in which normal observers made errors dependent on the visual context of the stimulus. The localization errors of the strabismic amblyope were abnormal. We found that none of the available theories could fully explain this one patient's localization performance. Instead, the observed behavior suggests that multiple adaptations of the underlying cortical topology are possible simultaneously in different parts of the visual field.     

Brain potentials elicited by prose-embedded linguistic anomalies

Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects' assigned task, syntactic anomalies elicited a large positive wave (P600), whereas semantic anomalies elicited a large increase in N400 amplitude. These results demonstrate that the qualitatively distinct ERP responses elicited by syntactic and semantic anomalies are not artifacts of unnatural aspects of previously used stimuli, thereby providing additional evidence that separable syntactic and semantic processes exist.     

Diagnosing organizational cultures: A conceptual and empirical review of culture effectiveness surveys

This review traces the development of survey research methods within the organizational culture tradition and focuses specifically on those instruments that measure the aspects of culture that are related to organizational effectiveness. Our review suggests that the reliability and validity of most instruments in this category is quite limited. This review outlines the recommended logic for the development and validation of culture effectiveness surveys and identifies three key challenges for future culture researchers to address: (1) the confirmatory testing of nested models, (2) the guidelines for aggregating data to the organizational level, and (3) the establishing of criterion-related validity. Using data from the Denison Organizational Culture Survey, we present an empirical illustration of the three challenges identified above and conclude by considering limitations and opportunities for future research.     

Hill on phenomenal consciousness

I argue that it is at least open to a proponent of type materialism for phenomenal consciousness to accept Hill’s representational theory of experiential awareness of perceptual qualia.     

Charisma, status, and gender in groups with and without gurus

A number of studies have noted that small religious groups with charismatic leaders seem to have different gender dynamics than do groups without. We argue that the presence of such a leader changes what charisma “means” in such a group. Without such a leader, strong personalities may appear charismatic and lead to positions of high status—and such dynamics historically have tended to be associated with a positional advantage to males. With such a leader, however, charisma is more likely to be compatible with receptivity and decoupled from gender characteristics that tend to disadvantage women, leading charismatic women to have greater status than they would otherwise have.     

Children's loneliness, sense of coherence, family climate, and hope: developmental risk and protective factors

The study examined the contributions of individual and familial variables for the prediction of loneliness as a developmental risk and the sense of coherence as a protective factor. The sample consisted of 287 children from grades 5-6. Their loneliness, sense of coherence, hope, effort, and family climate were assessed. Separate hierarchical multiple regression analyses revealed that family cohesion and children's hope contributed to the explanation of the risk and protective outcomes. Yet, the contribution of the family adaptability was not significant. Cluster analysis of the family climate dimensions (i.e., cohesion and adaptability) was performed to clarify the interactive roles of family adaptability together with family cohesion. The authors identified 4 separate family profiles: Children in the 2 cohesive families' clusters (Cohesive Structured Families and Cohesive Adaptable Families) reported the lowest levels of loneliness and the highest levels of personal strengths. Children within rigid and noncohesive family cluster reported the highest levels of loneliness and the lowest levels of children's sense of coherence. The unique role of the family flexibility within nonsupportive family systems was demonstrated. The results further clarified the unique profiles' characteristics of the different family clusters and their adjustment indexes in terms of loneliness and personal strengths.
