The association between gender, coping style and whiplash related symptoms in sufferers of whiplash associated disorder

The aim of the present study was to examine specifically whether the relationship between coping style and symptoms of whiplash injury change as a function of gender. A total of 1709 sufferers of whiplash associated disorder (1349 women, 360 men) belonging to the Danish Society for Polio, Traffic and Accident Victims completed questionnaires measuring demographic and psychological factors (including coping style), and symptoms of whiplash trauma (including pain). Men and women were not found to differ significantly in their use of coping strategies, however emotion focused coping strategies were related significantly more strongly to whiplash related symptoms in men compared to women. Women were found to display more symptoms related to whiplash injury compared to men. Possible reasons for the present findings are discussed in light of related research indicating mood as a potential moderating variable in the relationship between maladaptive coping style and degree of symptoms related to injury in men.     

Alpha3-integrins are required for hippocampal long-term potentiation and working memory

Integrins comprise a large family of heterodimeric, transmembrane cell adhesion receptors that mediate diverse neuronal functions in the developing and adult CNS. Recent pharmacological and genetic studies have suggested that beta1-integrins are critical in synaptic plasticity and memory formation. To further define the role of integrins in these processes, we generated a postnatal forebrain and excitatory neuron-specific knockout of alpha3-integrin, one of several binding partners for beta1 subunit. At hippocampal Schaffer collateral-CA1 synapses, deletion of alpha3-integrin resulted in impaired long-term potentiation (LTP). Basal synaptic transmission and paired-pulse facilitation were normal in the absence of alpha3-integrin. Behavioral studies demonstrated that the mutant mice were selectively defective in a hippocampus-dependent, nonmatch-to-place working memory task, but were normal in other hippocampus-dependent spatial tasks. The impairment in LTP and working memory is similar to that observed in beta1-integrin conditional knockout mice, suggesting that alpha3-integrin is the functional binding partner for beta1 for these processes in the forebrain.     

Using Concept Mapping to Operationalize Mental Well-Being for Men and Boys

A primary purpose of many prevention-oriented interventions is to improve the general well-being and quality of life for individuals and their communities. Unfortunately, well-being is often poorly defined, with definitions embracing related issues of quality of life, happiness, and physical health. Mental well-being as a concept is also poorly defined, particularly for different population groups. As part of a larger study to assess community-level prevention efforts aimed at men and boys, a participatory approach was used to operationalize mental well-being from a male-centered, community-based perspective using concept mapping. A set of 96 statements perceived as important aspects of mental well-being for men and boys were developed and sorted by 90 participants from the study communities. The 8-cluster solution was selected as the most parsimonious and the best conceptual fit in relation to the mental well-being concept, namely, positive self-worth, supportive community, community connections, positive masculinity, responsive institutions, strong social connection, dignity and respect, and safety. These eight clusters of mental well-being, which were classified into two overarching domains of socio-environmental and emotional well-being, can provide a basis by which to assess community-based programs aimed at this population.     

Measurement of the body surface physiologic tremor or “microvibration”

Five sensor techniques were evaluated for the measurement of human body surface vibrations: a noncontacting capacitance sensor, seismic (velocity) and relative electrodynamic types, linear-variable-differential transformer sensors, and the miniature accelerometer type. Of these, only the miniature accelerometer proved to be entirely satisfactory. The electrodynamic transducer utilized by several previous workers was found to be unsatisfactory for use as a physiological vibration sensor, due to resonance problems.     

Examining predictors and outcomes of a career calling among undergraduate students

The current study examined predictors and outcomes of a career calling among 292 undergraduate students at two time points over a three-month period. Using structural equation modeling, a model was tested that examined the extent to which calling, life meaning, the search for life meaning, vocational clarity, and personal growth at Time 1 would predict these same variables at Time 2. Results showed that calling was a significant predictor of personal growth and life meaning and that life meaning, the search for life meaning, and vocational self-clarity significantly predicted the presence of a calling. Although findings demonstrating calling as a predictor variable are consistent with previous research, these results also demonstrate the potential reciprocal relation of calling to proximal work and well-being variables over time. Implications and future research directions are discussed.     

Intrinsic Religiousness as a Mediator Between Fatalism and Cancer-Specific Fear: Clarifying the Role of Fear in Prostate Cancer Screening

Understanding factors that influence screening receptivity may enhance African-American men’s receptivity to prostate cancer screening. Men of African descent (N = 481) between the ages of 40 and 70 were recruited. The hypotheses that Fatalism would be related to Intrinsic Religiousness and Fear, Intrinsic Religiousness would act as a mediator between Fatalism and Fear, and Fatalism as well as Prostate Cancer-Specific Fear would be negatively related to past Prostate-Specific Antigen Testing and Screening Intent were supported. This meditational finding suggests that when religious beliefs are a motivating force, the fear-inducing effects of fatalism are reduced.     

Examining Moderators of Signature Strengths Use and Well-being: Calling and Signature Strengths Level

This study examined the relation between signature strengths use and satisfaction with a sample of diverse undergraduate students. We measured strengths use and satisfaction in both the life and academic domains and identified two possible moderators of this relation: the level of one’s signature strengths and the presence of calling. Results revealed a three way interaction between signature strengths use, signature strengths level, and calling in the prediction of life satisfaction and a two way interaction between signature strengths use and calling in the prediction of academic satisfaction. Contrary to our hypotheses, people low in calling and high in signature strengths level showed the strongest relation between signature strengths use and life satisfaction. For the academic domain, participants low in calling showed the strongest relation between strengths use and academic satisfaction but those high in calling still benefited from using their strengths. Implications for future research and limitations of the study are discussed.     

Ethics in Psychology and Law: An International Perspective

Some psychologists working in the psychology and law (psycholegal) field feel that the profession does not provide them with adequate ethical guidance even though the field is arguably one of the oldest and best established applied fields of psychology. The uncertainty psychologists experience most likely stems from working with colleagues whose professional ethics differs from their own while providing services to demanding people and the many moral questions associated with the administration of law. I believe psychology’s ethics does, however, provide adequate moral guidance. It has a sound historical basis, has face validity and emphasizes those social moral principles that allow psychologists to best serve individuals and society. Psychologists may nevertheless be confronted with conflicting demands because there are other norm systems that also regulate their behavior as researchers and practitioners, and they, like all people, are influenced by their conscience. Ultimately, psychologists working in the psycholegal field will be best served if they have good knowledge of, and have internalized, the ethical principles of psychology.
