Modeling the Indirect Association of Combat Exposure With Anger and Aggression During Combat Deployment: The Moderating Role of Perceived Unit Morale

Anger and aggression are common combat-related behavioral health problems. The impact of combat on anger and aggression appears to be largely attributable to symptoms of posttraumatic stress disorder (PTSD). Factors that moderate the purported pathway from combat to anger and aggression are poorly understood. We examined the conditional direct and indirect associations of combat exposure with self-reported anger and aggression using survey data collected from 592 U.S. Soldiers during a combat deployment in Afghanistan. Unit morale was examined as a moderator between combat exposure and PSTD symptoms, as well as the indirect association of combat exposure with anger and aggression via PTSD symptoms, controlling for depression symptoms. Results indicated that unit morale was negatively correlated with PTSD symptoms and self-reported anger and aggressive behaviors. Perceptions of unit morale moderated the direct association of combat exposure with PTSD symptoms. Unit morale also moderated the indirect association of combat exposure with anger and aggression through PTSD symptoms. Unit morale moderated the association of combat exposure with anger and aggression during combat operations by putatively mitigating the deleterious effect of combat on stress-related symptoms. The impact of policy and leadership on soldier and unit morale should be carefully considered given its protective role during combat operations.     

A new consequence of Simpson's paradox: stable cooperation in one-shot prisoner's dilemma from populations of individualistic learners

Theories of choice in economics typically assume that interacting agents act individualistically and maximize their own utility. Specifically, game theory proposes that rational players should defect in one-shot prisoners' dilemmas (PD). Defection also appears to be the inevitable outcome for agents who learn by reinforcement of past choices, because whatever the other player does, defection leads to greater reinforcement on each trial. In a computer simulation and 4 experiments, the authors show that, apparently paradoxically, when players' choices are correlated by an exogenous factor (here, the cooperativeness of the specific PD chosen), people obtain greater average reinforcement for cooperating, which can sustain cooperation. This effect arises from a well-known statistical paradox, Simpson's paradox. The authors speculate that this effect may be relevant to aspects of real-world human cooperative behavior.     

State-dependent and odor-mediated anemotactic responses of a micro-arthropod on a novel type of locomotion compensator

A novel type of locomotion compensator was designed and tested for its use in orientation behavior experiments with a predatory mite. In this apparatus, displacements of the test animal in the two-dimensional plane are recorded using video equipment and a servosphere that keeps the animal in focus. Thex andy displacements are registeredusing two rotation encoders and are compensated using a pair of servo-motors, in such a way that the animal is always positioned on top of the sphere, yet moves freely. Well-fed and starved predators were tested for their responses to (1) still air, (2) a stimulus-free air flow, (3) an air flow with odors from uninfested Lima bean leaves, and (4) an air flow with odors from Lima bean leaves infested by plant-feeding mites, the prey of the predatory mites. Anemotactic responses of adultPhytoseivlus persimilis females were feeding state dependent. Well-fed predators moved downwind under Treatments 1–3 but moved neither up-nor downwind in the presence of odors from infested plants (Treatment 4). Starved predators moved upwind under all treatments. These results are in agreement with those of earlier studies in a wind tunnel, and therefore, the new type of locomotion compensator (LC-100) offers an excellent method for studying the orientation behavior of micro-arthropods.     

Theism, Dualism, and the Scientific Image of Humanity

Recently, some philosophers of religion have suggested that a reduction of the classical image of humanity may jeopardize classical theism. To obstruct reductionism, some theologians have argued for dualism on the basis of the argument of consciousness. In this essay, I argue that even consciousness must be considered a brain-based phenomenon. This does not commit one to reductionism, however. Nonreductive physicalism appears to offer a promising alternative to either dualism or reductionism, without necessarily compromising more traditional views of humanity. I do suggest that a modification of the classical image of God may be inevitable.     

Psychometric properties of the Five Facets Mindfulness Questionnaire (FFMQ) in a meditating and a non-meditating sample

The factor structure, internal consistency, construct validity, and predictive validity of the Dutch version of the Five Facet Mindfulness Questionnaire (FFMQ-NL) were studied in a sample of meditators (n = 288) and nonmeditators (n = 451). A five-factor structure was demonstrated in both samples, and the FFMQ-NL and its subscales were shown to have good internal consistencies. Meditators scored higher on all facets of the FFMQ-NL than the participants in the nonmeditating sample. For both samples, expected negative correlations between most mindfulness facets (all except for the Observing facet) and the constructs of alexithymia, thought suppression, rumination, worry, and dissociation were found. The Observing facet of the FFMQ-NL showed an unexpected positive correlation with thought suppression in the nonmeditating sample. Furthermore, as expected, mindfulness facets were negatively related to psychological symptoms, and all mindfulness facets except for Observing and Describing significantly predicted psychological symptoms. Overall, the Dutch FFMQ demonstrated favorable psychometric properties, commensurate with its (original) English language version.     

Understanding alexithymia within a psychoanalytical framework

The object of this paper is to provide a metapsychological definition of alexithymia as described in 1967 in terms of operational thinking and negative hallucination. This is a familiar and established concept in the fields of psychopathology, psychology, and of clinical and psychosomatic medicine. From a psychoanalytic and psychosomatic point of view, the term is conceptually close to P. Marty's “operative thinking”, as described in 1963, even though we know they do not belong to the same epistemological field: on one hand Neuroscience, Psychiatry and the objectalization of the symptom at different levels, and on the other, as regards mechanical functioning, a psychoanalytic clinical approach within the dynamics of the relationship between transference and counter‐transference. The present authors consider that Freudian metapsychology, as now complexified by Andrè Green, allows for a metapsychological approach to alexithymia insofar as it relates to Marty's operative thinking. Thus does Green’s conceptualization of the mother’s negative hallucination, of negative introjection, of a psychically ‘dead (and insecure) mother’, now provide us with the opportunity to describe, in metapsychological terms, the genesis of this particular mode of psychical functioning. Given the mother’s negative hallucination produces a host structure as a background to negativity that will fit future object representations, we will assume that in the case of … future operational or alexithymic …?, this negative hallucination will pathologically and defensively involve the endo‐psychic perception of affect.     

The Role of Religion in the Work Lives and Coping Strategies of Ugandan Nurses

Nursing in Uganda is a highly stressful, underpaid profession, leading to worrisome attrition levels; yet some nurses do manage to stay on the job and thrive. This study explored the ways in which religion influences the work lives and coping strategies of Ugandan nurses who thrive despite job stress. Participants were 15 female nurses working in faith-based and non-faith-based facilities in Uganda. The nurses were all actively religious people, a fact not known at the time they were recruited. All the nurses revealed that religious values affected their performance positively, enabling them to find meaning even in the face of adversity.     

Enhancing young people's social competence and health behavior: An important challenge for educators, scientists, policymakers, and funders

Large numbers of America's young people engage in multiple high-risk behaviors that may jeopardize their health and social development. Given the gravity of this situation, many federal agencies and national organizations have called for the implementation of school-based K-12 social competence and health promotion programs. Unfortunately, there is a gap between the comprehensive programs that policymakers are asking educators to implement and the limited scope, duration, and intensity of state-of-the-art health promotion programs that scientists have developed and evaluated. As a result, most schools currently adopt well-marketed programs that lack documented effectiveness. Although current research indicates that brief, well-designed, theory-driven competence promotion and health education programs produce short-term benefits, there have been no controlled, longitudinal field studies to evaluate the long-term effects of K-12 efforts. This paper proposes that policymakers and funding agencies support long-term collaborations among educators and scientists to develop and evaluate K-12 comprehensive social competence and health education programs and identifies critical issues that funded projects should address.     

Raising the bar on the body beautiful: An analysis of the body image concerns of homosexual men

Research suggests that gay men are at particular risk for body image dissatisfaction. This study seeks to extend research on gay men's body image concerns. A survey assessed the nature and correlates of body image dissatisfaction among 64 gay men. The survey included assessments related to involvement in and perceived acceptance within the gay community, social comparison tendencies, body image satisfaction, self-esteem, and depression. The results indicate that most participants were concerned with muscularity rather than weight. Greater social comparison tendencies and higher body mass index (BMI) were associated with greater body dissatisfaction. Although involvement and perceived acceptance in the gay community did not independently predict general body image dissatisfaction, there is evidence to suggest that the association between body image and self-esteem may be moderated by integration into the gay community, defined as involvement and perceived acceptance. Implications for the further study of gay men's body image are discussed.
