Modeling the bullying prevention program design recommendations of students from grades five to eight: a discrete choice conjoint experiment

We used a discrete choice conjoint experiment to model the bullying prevention recommendations of 845 students from grades 5 to 8 (aged 9-14). Students made choices between experimentally varied combinations of 14 four-level prevention program attributes. Latent class analysis yielded three segments. The high impact segment (27.1%) recommended uniforms, mandatory recess activities, four playground supervisors, surveillance cameras, and 4-day suspensions when students bully. The moderate impact segment (49.5%) recommended discretionary uniforms and recess activities, four playground supervisors, and 3-day suspensions. Involvement as a bully or bully-victim was associated with membership in a low impact segment (23.4%) that rejected uniforms and surveillance cameras. They recommended fewer anti-bullying activities, discretionary recess activities, fewer playground supervisors, and the 2-day suspensions. Simulations predicted most students would recommend a program maximizing student involvement combining prevention with moderate consequences. The simulated introduction of mandatory uniforms, surveillance cameras, and long suspensions reduced overall support for a comprehensive program, particularly among students involved as bullies or bully-victims.     

Learning a spatial skill for surgery: how the contributions of abilities change with practice

We examined changes in performance as people learned to use an angled laparoscope, a challenging spatial skill that must be mastered by surgeons who perform minimally invasive techniques. In Experiment 1, novices took tests of spatial and general reasoning ability, and then learned to operate an angled laparoscope, simulated in a virtual environment, over 12 learning sessions. Initial performance showed considerable variability among learners, with performance related to general and spatial abilities. As learning progressed, interindividual variability diminished and all learners attained proficiency; the correlation with general ability diminished but the correlation with spatial ability remained significant. In Experiment 2, performance by highly experienced surgeons on the simulation was excellent from the first session, confirming its ecological validity. The findings contribute to theories of skill acquisition. They also have practical implications for the selection of surgeons and for the potential use of virtual environments in surgical training.

Trauma awareness and preparedness: Their influence on posttraumatic stress disorder development related to armed conflict experience

This study examined influences of trauma awareness and preparedness on the development of posttraumatic stress disorder (PTSD) in civilian and military personnel with exposure to the civil war. Participants were 302 people with exposure to civil war in the Democratic Republic of Congo (civilians = 68%; females = 47%; age range = 16 to 76 years old, SD = 13.58 years). Participants completed the Posttraumatic Checklist Scale, General Self-Efficacy Scale, and Traumatic Events List. The data were analysed to predict PTSD development from trauma awareness and preparedness, taking exposure to multiple traumas into account as a risk factor. Findings suggest that trauma awareness and preparedness play an important role among military personnel in moderating the risk of developing PTSD, more so than among the civilian population. Mental health professionals working with civil war survivors should seek to explore trauma awareness and preparedness as resources for minimising risk for PTSD in armed conflict situations.     

Competing top-down processes in visual selection: evidence that selection by location is stronger than selection by color

The purpose of this study was to examine whether color and position information are functionally equivalent when observers are asked to select simultaneously on both dimensions. Observers were asked to report a letter of a given color from a given region of a briefly flashed letter array, then to report any additional letters they could recall from the stimulus set. Of the additional letters, more location letters were reported than were same-color or neutral letters. The results suggested that position information has priority over color information in top-down-guided visual selection.

Friendly fire: Longitudinal effects of exposure to violent video games on aggressive behavior in adolescent friendship dyads

Research on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents’ exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, M_age = 13.98). Actor‐Partner Interdependence Models indicated that adolescent males’ (but not females’) exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression.     

Burnout in Christian Perspective

Mindfulness and Christian spirituality are useful tools in preventing and coping with burnout and compassion fatigue. Christian human services workers who engage in these practices are able to stave off burnout and actually be revitalized in their work because mindfulness and Christian spirituality are tied to managing loss of personal accomplishment, emotional exhaustion, and depersonalization. For Christians, a better way to conceptualize burnout and compassion fatigue is to consider them within the categories of calling, apathy, and indifference. In this way, preventing and coping with burnout becomes a project of spiritual revitalization—reconnecting with the empowering, living spirit of God. The practices of the Jesus Prayer, the daily examen, and the prayer of consideration are useful tools for accomplishing this.     

Landmarks as beacons and associative cues: Their role in route learning

Relatively little is known about how people use the landmarks in their environment to learn routes. Landmarks are commonly regarded as associative cues--stimuli that enable recall of directional responses that lead closer to the navigator's goal. We contrast the function of landmark as associative cue with that of a beacon-a landmark near enough to a goal that moving toward it leads the navigator closer to his or her goal. In five experiments, participants learned a route through a simple desktop virtual environment. In the first three experiments, routes were learned better when their landmarks served as beacons than as associative cues. Two additional experiments showed that the acquired route knowledge depends on the function that landmarks serve during learning. Beacon-based route knowledge is less enduring and relatively less likely to involve knowledge of directions in the environment than is the route knowledge formed from landmarks that serve as associative cues.     

The Facticity of Explanation and Its Consequences

This paper argues that, contrary to the views of Nancy Cartwright and Brian Ellis, explanations are factive: if a statement is taken to be an explanation, it also has to be accepted as true. Taking explanations to be true, in turn, seems to imply that all the entities posited in explanations are real. But this is precisely what some philosophers, such as Cartwright and Ellis, want to deny. What these philosophers do not want to deny, however, is that such statements do explain. As a result, they see themselves forced to reject the facticity of explanation, a strategy that is unacceptable in my view. In order to avoid the further conclusion that all of the entities explanations posit exist, I propose to separate truth from ontology: explanations can be true, but the truth of these explanations alone does not commit us to the entities that these explanations posit. To determine where the ontological commitments of our statements lie, we must instead start with a criterion (a necessary and sufficient condition) for what exists. For instance, if all and only entities with causal powers are real, then this tells us that the only entities our true statements are committed to are entities with causal powers.     

Systems-Centered Therapy: A Protocol for Treating Generalized Anxiety Disorder

The systems-centered short-term therapy protocol was adapted and applied in three single case studies with generalized anxiety disorder (GAD) patients in a ten-session individual treatment over a two week period. All three subjects showed substantial improvement and no longer met diagnostic criteria post-treatment. Changes were maintained at follow up both six months and one year later. These results are promising and suggest the importance of further research on SCT as a viable, alternative treatment for generalized anxiety disorder.
