Implementation of a Suicide Nomenclature within Two VA Healthcare Settings

Suicide and suicide attempts are significant issues for military, Veterans Affairs (VA), and civilian healthcare systems. The lack of uniform terms related to self-directed violence (SDV) has inhibited epidemiological surveillance efforts, limited the generalizability of empirical studies of suicide and non-lethal forms of SDV, and complicated the implementation of evidence-based assessment and treatment strategies for individuals with suicidal thoughts and/or behaviors. The Department of Veterans Affairs recently adopted the Centers for Disease Control and Prevention’s (CDC) SDV Classification System (SDVCS). This paper describes an implementation study of the SDVCS in two VA Medical Centers. The Veterans Integrated Service Network (VISN) 19 Mental Illness Research, Education and Clinical Center (MIRECC) training program for the SDVCS, including the SDVCS Clinical Tool (CT), will be discussed. Although preliminary data suggest that the CT and SDVCS are generally perceived as being acceptable and useful, further work will likely be required to facilitate widespread adoption. Potential next steps in this process are presented.     

Judging the 'passability' of dynamic gaps in a virtual rugby environment

Affordances have recently been proposed as a guiding principle in perception–action research in sport (Fajen, Riley, & Turvey, 2009). In the present study, perception of the ’passability’ affordance of a gap between two approaching defenders in rugby is explored. A simplified rugby gap closure scenario was created using immersive, interactive virtual reality technology where 14 novice participants (attacker) judged the passability of the gap between two virtual defenders via a perceptual judgment (button press) task. The scenario was modeled according to tau theory (Lee, 1976) and a psychophysical function was fitted to the response data. Results revealed that a tau-based informational quantity could account for 82% of the variance in the data. Findings suggest that the passability affordance in this case, is defined by this variable and participants were able to use it in order to inform prospective judgments as to passability. These findings contribute to our understanding of affordances and how they may be defined in this particular sporting scenario; however, some limitations regarding methodology, such as decoupling perception and action are also acknowledged.     

High Aspirations: Differences in Employee Satisfaction Between University Faculty and Staff

Employee satisfaction surveys were examined for five universities in the US, UK and Canada, selected because they presented results for faculty and other staff separately. Faculty consistently score more negatively on employee satisfaction across a wide range of areas. The most negative responses are for areas such as personal/worklife balance, work demands/workload, university direction, and whether the employee would choose to work at the same institution again/would recommend it for employment. The results are consistent with previous studies which have shown that education level is negatively associated with job satisfaction. The results suggest that university faculty have high aspirations, since in a number of indicators faculty working conditions appear superior to those of staff (tenure; average income; sabbatical leaves; work control; involvement and consultation in university decision-making), although junior faculty prior to tenure may experience more stress than staff. Employers undertaking employee satisfaction surveys need to take into account systematic differences in aspirations among their employees, when interpreting survey results.     

Enlightenment and individuation: syncretism,synchronicity and beyond

This paper opens with a personal introduction to the topic of syncretism within the context of a comparison of enlightenment associated with Eastern religious traditions and individuation as experienced through Jungian analysis. A brief exploration of the recent scholarly revival of interest in syncretism follows. Some close parallels with Jungian theory are highlighted, especially in the work of Timothy Light. Applications to the syncretic trends in Tang culture along the Silk Road(s) suggest deeper patterns of interconnectedness lie at the heart of these trends. A complex systems view highlights similarities between syncretic connections and non‐local aspects of synchronistic field events. The final section attempts to extend this approach to innovation in general terms through the recently articulated concept of the ‘adjacent possible’ from the writing of Stuart Kauffman. From this, the notion of a collective pre‐conscious dimension to the psyche is extrapolated. The unifying thread of acausal emergent forms provides a potential synthetic network for these phenomena.     

What's wrong with cross-cultural comparisons of subjective Likert scales?: The reference-group effect

Social comparison theory maintains that people think about themselves compared with similar others. Those in one culture, then, compare themselves with different others and standards than do those in another culture, thus potentially confounding cross-cultural comparisons. A pilot study and Study 1 demonstrated the problematic nature of this reference-group effect: Whereas cultural experts agreed that East Asians are more collectivistic than North Americans, cross-cultural comparisons of trait and attitude measures failed to reveal such a pattern. Study 2 found that manipulating reference groups enhanced the expected cultural differences, and Study 3 revealed that people from different cultural backgrounds within the same country exhibited larger differences than did people from different countries. Cross-cultural comparisons using subjective Likert scales are compromised because of different reference groups. Possible solutions are discussed.     

Comparing techniques for estimating automatic retrieval: effects of retention interval

Results from implicit memory (IM) tasks suggest that automatic retrieval remains stable or decreases over time. In contrast, results from the process dissociation approach (PDA) suggest that automatic retrieval may actually increase over time. One explanation for these discrepant results is that performance on IM tasks is contaminated by controlled retrieval strategies, thereby overestimating automatic retrieval, particularly at short retention intervals, when controlled retrieval strategies are high. An alternative explanation is that automatic and controlled retrieval are positively correlated, rather than independent as assumed by the PDA. If so, the PDA would underestimate automatic retrieval, particularly when controlled retrieval strategies are high. Results from a speeded IM task suggest that a standard IM task provided an accurate estimate of automatic retrieval, whereas the PDA underestimated automatic retrieval at a short retention interval. This pattern of underestimation by the PDA supports the conclusion that automatic and controlled retrieval were positively correlated rather than independent.     

Differences in brain morphology and working memory capacity across childhood

Working memory (WM) skills are closely associated with learning progress in key areas such as reading and mathematics across childhood. As yet, however, little is known about how the brain systems underpinning WM develop over this critical developmental period. The current study investigated whether and how structural brain correlates of components of the working memory system change over development. Verbal and visuospatial short‐term and working memory were assessed in 153 children between 5.58 and 15.92 years, and latent components of the working memory system were derived. Fractional anisotropy and cortical thickness maps were derived from T1‐weighted and diffusion‐weighted MRI and processed using eigenanatomy decomposition. There was a greater involvement of the corpus callosum and posterior temporal white matter in younger children for performance associated with the executive part of the working memory system. For older children, this was more closely linked with the thickness of the occipitotemporal cortex. These findings suggest that increasing specialization leads to shifts in the contribution of neural substrates over childhood, moving from an early dependence on a distributed system supported by long‐range connections to later reliance on specialized local circuitry. Our findings demonstrate that despite the component factor structure being stable across childhood, the underlying brain systems supporting working memory change. Taking the age of the child into account, and not just their overall score, is likely to be critical for understanding the nature of the limitations on their working memory capacity.     

Conversation level syntax similarity metric

The syntax and semantics of human language can illuminate many individual psychological differences and important dimensions of social interaction. Accordingly, psychological and psycholinguistic research has begun incorporating sophisticated representations of semantic content to better understand the connection between word choice and psychological processes. In this work we introduce ConversAtion level Syntax SImilarity Metric (CASSIM), a novel method for calculating conversation-level syntax similarity. CASSIM estimates the syntax similarity between conversations by automatically generating syntactical representations of the sentences in conversation, estimating the structural differences between them, and calculating an optimized estimate of the conversation-level syntax similarity. After introducing and explaining this method, we report results from two method validation experiments (Study 1) and conduct a series of analyses with CASSIM to investigate syntax accommodation in social media discourse (Study 2). We run the same experiments using two well-known existing syntactic metrics, LSM and Coh-Metrix, and compare their results to CASSIM. Overall, our results indicate that CASSIM is able to reliably measure syntax similarity and to provide robust evidence of syntax accommodation within social media discourse.     

The contributions of religious practice,existential certainty,and raising grandchildren to well-being in older adults

ABSTRACT

Religious beliefs and practices are believed to foster well-being across the life course. This study examines whether religious practice, spiritual development, and existential certainty are positively linked to well-being in grandparents (N = 2,503) and whether these factors buffer grandparents from risks associated with raising grandchildren and adjusting to changing roles. Data were collected from individuals attending Protestant churches. Spiritual development and existential certainty were positively associated with well-being. We found no evidence for buffering effects of religious practice on grandparent well-being. Grandparents raising grandchildren reported more challenges in adjusting to changes in roles compared to their peers.
