Channels of Change: Contrasting Network Mechanisms in the Use of Interventions

This study informs community science, and seeks to narrow the research-to-practice gap, by examining how the interpersonal networks within a setting influence individuals' use of interventions. More specifically, it explores the role of two network mechanisms-cohesion and structural similarity-in urban elementary school teachers' use of interventions designed to improve academic and behavioral outcomes for students. Lagged regression models examine how position in advice giving networks influenced weekly use of the daily report card and peer assisted learning by kindergarten through fourth grade teachers in three schools. Results indicate that intervention use spreads among teachers with similar patterns of advice-giving relationships (i.e., via structural similarity), rather than from teachers who are sources of advice (i.e., via cohesion). These results are consistent with findings in other settings, and suggest that researchers wishing to increase the use of an intervention should select change agents based on their patterns of their relationships, rather than on their direct connections.     

Greed is good? Student disciplinary choice and self-reported psychopathy

The idea of the organisational psychopath has become not only popular in recent times, but increasingly relevant, thanks to the alleged role of high-profile members of the commercial sector in the global recession. To test the proposition that self-reported sub-clinical psychopathy might be disproportionately more common amongst those people electing to study commerce/business at University, 903 first-year students enrolled in a range of academic degrees completed a survey containing Levenson’s Self-Report Psychopathy Scale (Levenson, Kiehl, & Fitzpatrick, 1995) and Paulhus’ (1991) Balanced Inventory of Desirable Responding. Even after accounting for social desirability, commerce students reported higher levels of primary psychopathy than other students, regardless of sex.     

Magnitude and chronometry of neural mechanisms of emotion regulation in subtypes of aggressive children

Emotion regulation is a key social skill and children who fail to master it are at risk for clinical disorders. Specific styles of emotion regulation have been associated with particular patterns of prefrontal activation. We investigated whether anxious aggressive children would reveal a different pattern of cortical activation than non-anxious aggressive children and normally-developing children. We examined the magnitude and timing of source activation underlying the N2—an ERP associated with inhibitory control—during a go/nogo task with a negative emotion induction component (loss of earned points). We estimated cortical activation for two regions of interest—a ventral prefrontal and a dorsomedial prefrontal region—for three 100-ms windows over the range of the N2 (200–500 ms). Anxious aggressive children showed high ventral prefrontal activation in the early window; non-anxious aggressive children showed high ventral prefrontal activation in the late window, but only for the duration of the emotion induction; and normally-developing children showed low ventral prefrontal activation throughout. There were no group differences in dorsomedial prefrontal activation. These results suggest that anxious aggressive children recruit ventral prefrontal activation quickly and indiscriminately, possibly giving rise to their rigid, threat-oriented approach to conflict. The late ventral prefrontal activation seen for non-anxious aggressive children may underlie a more delayed, situation-specific, but ineffective response to frustration.     

An ecological study of community-level correlates of suicide mortality rates in the Flemish region of Belgium, 1996-2005

An ecological study of age-standardized suicide rates in Belgian communities (1996-2005) was conducted using spatial regression techniques. Community characteristics were significantly related to suicide rates. There was mixed support for the social integration perspective: single person households were associated with higher suicide rates, while religious participation was unrelated and both immigration and the presence of non-European inhabitants had a negative impact. Deprivation had a positive relation with suicide. Population density had a negative influence on suicide rates. Areas with older populations had higher suicide risks than expected. A spatial contagion effect of neighboring communities was present for men. In the conclusion, hypotheses are presented on why an aging population could be associated with higher suicide rates in the community.     

Fine's Fragmentalist Interpretation of Special Relativity

In “Tense and Reality”, Kit Fine ( 2005 ) proposed a novel way to think about realism about tense in the metaphysics of time. In particular, he explored two non‐standard forms of realism about tense (“external relativism” and “fragmentalism”), arguing that they are to be preferred over standard forms of realism. In the process of defending his own preferred view, fragmentalism, he proposed a fragmentalist interpretation of the special theory of relativity (STR), which will be our focus in this paper. After presenting Fine's position, we will raise a problem for his fragmentalist interpretation of STR. We will argue that Fine's view is in tension with the proper explanation of why various facts (such as the Lorentz transformations) obtain. We will then consider whether similar considerations also speak against fragmentalism in domains other than STR, notably fragmentalism about tense.     

The Presence of Self-Stigma,Perceived Stress,and Suicidal Ideation among Selected LGBT Filipinos

Minority group members experience what is known as “minority stress,” by which individuals suffer stress because of their membership in stigmatized social categories. In turn, minority stress may lead to self-stigmatization. This occurs when minority group members experience a sense of shame created by the view of the majority culture and then incorporate the majority opinion into their self-image. Because it is cumulative with the stress an individual is already experiencing, self-stigmatization may become a significant stressor itself, possibly contributing to the development of suicidal ideation. A total of 609 self-identified LGBT individuals were asked to answer a battery of psychological tests to assess the interrelationships between self-stigma, perceived stress, and suicidal ideation. As expected, perceived stress predicted suicidal ideation, whereas self-stigmatization predicted both perceived stress and suicidal ideation. Structural equation modeling confirms the predictive value of self-stigma together with perceived stress in determining the suicidal ideation present among LGBT Filipinos. Self-stigma exerted a direct effect upon suicidal ideation not accounted for by perceived stress.     

Digital lives in psychotherapy: ‘the other in the room’

Within the broader area of digital risk, there has been concern over the phenomena of ‘cyber suicide’, a completed or attempted suicide influenced by the internet. We propose a theoretical explanation of the ‘ambivalent self’ in people who go online searching for suicide, by introducing the concept of an inner split between the ‘suicidal part’ (SP) and ‘non-suicidal part’ (NSP) within the personality structure of the individual which struggle for domination of the inner life and external relationships and decisions of the suicidal person. This is grounded in psychoanalytic theory and draws upon a broader conceptualisation of the psyche of the self as split between rival parts, and differing states of mind, competing for control of the vulnerable individual and their capacity to tolerate and manage emotional pain and reality. The recognition and awareness of an inner split between the SP and NSP of the person who goes online, and how this influences virtual relationships, as well as external relationships, such as in psychotherapy, is an important understanding for contemporary psychotherapy and risk management in the digital age.     

Flow at Work and Basic Psychological Needs: Effects on Well‐Being

Recent conceptual work draws meaningful distinctions between experiential and declarative well‐being (Shmotkin, 2005 ), but little has been done to apply such distinctions in organisational psychology. We use this framework to integrate self‐determination theory (Deci & Ryan, 1985 ) and flow theory (Csikszentmihalyi, 1975 ), leading to hypotheses proposing that flow experiences at work (experiential well‐being) lead to declarative well‐being outcomes through their influence on the satisfaction of basic psychological needs for competence and autonomy. Findings from a two‐week experience sampling study of full‐time employees offer support for our hypotheses. This study also shows support for the moderating effect of individual differences in personality on the relationships among flow experiences, need fulfillment, and declarative well‐being.
