Geographic Hotspots of Critical National Infrastructure

Failure of critical national infrastructures can result in major disruptions to society and the economy. Understanding the criticality of individual assets and the geographic areas in which they are located is essential for targeting investments to reduce risks and enhance system resilience. Within this study we provide new insights into the criticality of real‐life critical infrastructure networks by integrating high‐resolution data on infrastructure location, connectivity, interdependence, and usage. We propose a metric of infrastructure criticality in terms of the number of users who may be directly or indirectly disrupted by the failure of physically interdependent infrastructures. Kernel density estimation is used to integrate spatially discrete criticality values associated with individual infrastructure assets, producing a continuous surface from which statistically significant infrastructure criticality hotspots are identified. We develop a comprehensive and unique national‐scale demonstration for England and Wales that utilizes previously unavailable data from the energy, transport, water, waste, and digital communications sectors. The testing of 200,000 failure scenarios identifies that hotspots are typically located around the periphery of urban areas where there are large facilities upon which many users depend or where several critical infrastructures are concentrated in one location.     

“Just Like I'm Saving Money in the Bank”: Client Perspectives on Care Coordination Services

Older adults face many challenges to community living. The literature has not sufficiently explored the roles of care coordination in the maintenance of housing and access to health care among older adults, particularly from their own perspectives. This qualitative study analyzes the findings from 25 interviews and 6 focus group discussions (48 participants) with a multiethnic sample of older adults in the New York City area. Care coordination services appear to assist older adults access health care, and to a lesser extent, maintain affordable housing. Disparities in access to care coordination appear to remain for immigrant, minority and suburban populations.     

Validation of the Postpartum Social Support Questionnaire in low-income,African American women

ABSTRACT

This study applied a previously developed Postpartum Social Support Questionnaire to low-income, African American women. The 33-question survey was administered to 95 African American women between 4- and 8-weeks postpartum. The survey was readministered 2 weeks later. All women were of low socioeconomic status based on their qualification for public insurance. The questionnaire addresses subscales of partner, parent, in-law, and other friend/relative support. Responses were used to evaluate internal reliability of each subscale, test–retest correlation, and factor loading. Results were compared between women with and without a positive postpartum depression screen. Cronbach's alpha coefficients for each subscale ranged from .90 to .96. Test-retest correlation coefficients ranged from .72 to .87. Exploratory factor analysis with orthogonal varimax rotation was consistent with previously studied samples. Those women with positive postpartum depression screens had significantly lower social support scores (M = 122, SD = 36) than women with negative postpartum depression screens (M = 149, SD = 38), t(79) = ?2.62, p = .01. The Postpartum Social Support Questionnaire is a useful assessment in low-income, African American mothers.     

Revisiting the biological perspective in the use of biopsychosocial assessments in social work

ABSTRACT

The call for increased attention to the biopsychosocial perspective in social work practice is now decades old in the USA. And yet the challenge of teaching and learning from this perspective for those with limited background in biology calls for more inter-disciplinary examples to assist students with the process of engaging in theory-informed practice. In addition to identifying the key elements of human biology, this review of the literature focuses on four examples of client behaviors that receive little or no attention in most current textbooks on the inter-disciplinary nature of human behavior in the social environment; namely, the psychobiology of sleep, the sociobiology of eating, the neurobiology of post-partum depression, and the behavioral endocrinology of menopause. This review concludes with implications for practice.     

Patterns of mutual exclusivity and retention: A study of monolingual and bilingual 2-year-olds

When children learn their native language, they tend to treat objects as if they only have one label—a principle known as mutual exclusivity. However, bilingual children are faced with a different cognitive challenge—they need to learn to associate two labels with one object. In the present study, we compared bilingual and monolingual 24-month-olds’ performance on a challenging and semi-naturalistic forced-choice referent selection task and retention test. Overall, both language groups performed similarly on referent selection but differed on retention. Specifically, while monolingual infants showed some retention, bilingual infants performed at chance and significantly worse than their monolingual peers.     

What Do We Do When We Discuss? A Micro‐genetic Analysis of Couples’ Conflict

This article focuses on dialogic discursive dynamics present in couples’ conversations about unresolved conflicts. The phenomenon of conflict is addressed as a semiotically mediated process of co‐construction of the self and the relationship. The purpose of this article is to report on patterns of meaning construction in couples’ conflict, with the identification of strategies that promote or hinder resolution. A qualitative exploratory approach was used to focus on the interactional process at the micro‐processing level. Eight married couples participated in the study. The procedure considered asking the couple to discuss unresolved conflict. Recorded data of couples’ dialogues were transcribed to text and assessed through semiotic analysis using a microgenetic protocol (Molina, Del Río, & Tapia, 2015). The results document the use of strategies for conflict regulation such as psychological distancing, opposition, and generalisation on the border between protecting the bond and regulating tension. The dynamics of non‐resolution manifested in polarisation and rigid patterns with increased tension. The ‘in‐motion’ nature of dialogue about conflict is pushed by the semiotic tension that induces variations in subjective positions manifested in speech and actions.     

Experiences of student veterans with social anxiety and avoidance: A qualitative study

Eight-to-ten percent of returning combat veterans report symptoms of Posttraumatic Stress Disorder (PTSD), of which 7–13% also report symptoms of Social Anxiety Disorder. Both disorders are characterized by maladaptive patterns of social functioning, which can have significant effects on the lives of returning combat veterans and increase suicidal risk. The objective of the present study was to identify elements of the lived experience of college student veterans experiencing social anxiety and avoidance. Twelve student veterans with post-9/11 active duty service were interviewed about their lived experiences with social anxiety/avoidance within the framework of phenomenological theory. Data was analyzed using multilevel coding and theme analysis. Analysis of interview themes (n = 12) clarified university campus environments that induce social anxiety/avoidance and the impact on personal and professional relationships, learning, and navigation of physical space. Implications of this study include addressing student veterans’ needs through clinical intervention and further representative research on prevalence rates of these risk factors in various university and community college settings.     

Infants' ERP Responses to Novel and Familiar Stimuli Change Over Time: Implications for Novelty Detection and Memory

Detection of novelty is an important cognitive ability early in development, when infants must learn a great deal about their world. Work with adults has identified networks of brain areas involved in novelty detection; this study investigated electrophysiological correlates of detection of novelty and recognition of familiarity in 9‐month‐old infants, using event‐related potentials (ERPs). Infants were familiarized with an event in the laboratory, then ERPs were recorded as they viewed repeated presentations of pictures of this familiar event and a novel event, along with single presentations of 30 trial‐unique events. A middle‐latency negative component was sensitive to degree of novelty, differing in amplitude and latency by stimulus condition and across repeated presentations. Long‐latency slow‐wave activity also related to stimulus condition. Findings have implications for our understanding of infants' detection of novel information and the processes that render the novel familiar.
