Framing public policy and prevention of chronic violence in American youths

Metaphors can both inspire and mislead the public. Current metaphors for youth violence are inconsistent with scientific evidence about how chronic violence develops and evoke inaccurate or harmful reactions. Popular, problematic metaphors include superpredator, quarantining the contagious, corrective surgery, man as computer, vaccine, and chronic disease. Four new metaphors that more accurately reflect the science of child development are proposed to shape the field. Preventive dentistry offers a lifelong system of universal, selected, and indicated intervention policies. Cardiovascular disease offers concepts of distal risk factors, proximal processes, equifinality and multifinality, and long-term prevention. The Centers for Disease Control and Prevention's public health model focuses on injury and the victim to elicit popular support. Public education for illiteracy offers concepts of long-term universal education coupled with specialized help for high-risk youths and goes beyond metaphor to represent a truly applicable framework. Research is proposed to test the scientific merit for and public receptivity to these metaphors.     

The Interplay of Temperament and Regulatory Focus on Consumer Problem‐Solving Modes

Regulatory Focus Theory's two fundamental processing orientations, Prevention Focus and Promotion Focus, have been shown to capture important differences in problem‐solving motivation, goal pursuit, and individual‐task ‘fit’, although some ambiguity remains regarding the nature of these differences; they have been construed as chronic but have also been related to specific situational factors. Separately, understandings of temperament (hereditable, physiological‐based individual differences) have advanced significantly, although efforts to validate measures of temperament have been frustrating. Reinforcement Sensitivity Theory posits two fundamental temperaments, the Behavioral Inhibition System (an avoidance system sensitive to punishments and threats) and the Behavioral Activation System (an appetitive/approach system sensitive to rewards). We relate Regulatory Focus Theory to Reinforcement Sensitivity Theory, initiating the integration of Promotion Focus and Prevention Focus with the extensive extant theory and nomological networks of temperament and highlighting conspicuous empirical divergence between the two systems.     

Do allogeneic bone marrow transplant candidates match coping to controllability of pre-treatment stressors?

According to the Person x Situation theoretical framework, people adjust their coping to address the unique challenges of encountered stressors. Whether their strategies fit or appropriately address these stressor challenges influences adjustment. We examined the fit between pre-treatment stressors reported by hematological cancer patients awaiting allogeneic bone marrow transplantation (alloBMT) and their coping responses. Stressors were categorized as controllable versus uncontrollable; coping responses were categorized as problem- versus emotion-focused versus mixed (i.e., elements of both coping types). We hypothesized that patients would employ coping responses that fit the controllability of stressors (i.e., a match between stressor and coping response): problem-focused coping for controllable stressors and emotion-focused coping for uncontrollable stressors. In qualitative interviews, pre-BMT patients (10 men, 7 women) described encountered stressors and how they coped with them. Every reported stressor was linked with its associated coping response, resulting in a stressor-coping pair. We determined the proportion of total stressor-coping pairs in which the coping response matched the controllability of its linked stressor. Most stressor-coping pairs involving uncontrollable stressors showed the hypothesized match with emotion-focused or mixed coping. Contrary to hypotheses, fewer stressor-coping pairs that involved controllable stressors matched with problem-focused or mixed coping. Rather, these pairs were more likely to link controllable stressors with emotion-focused coping (i.e., mismatch between stressor controllability and type of coping). AlloBMT candidates may appraise the pre-treatment stage, globally, as permitting very little control. Coping efforts may consequently emphasize regulation of negative emotions (i.e., emotion-focused coping).     

Health-related quality of life in chronic fatigue syndrome: predictors of physical functioning and psychological distress

This study investigated health-related quality of life (HRQoL; physical functioning and psychological distress) in an Australian chronic fatigue syndrome (CFS) population. The aims of the study were to compare HRQoL in those with CFS to the normal population, and to investigate the extent to which sociodemographic (age, gender, partner status, education), illness-related (illness duration, symptom frequency), and fatigue severity (physical, mental) variables predicted HRQoL. A total of 139 people meeting CFS criteria completed questionnaires. HRQoL was assessed using standardised measures of distress and physical functioning. Compared with norms, those with CFS obtained significantly lower scores on all physical functioning areas, whereas 63% of participants reported clinically significant psychological distress. Hierarchical regression analyses indicated that physical fatigue severity and symptom frequency were the strongest predictors of deficits in physical domain HRQoL. Physical HRQoL outcomes were also predicted by mental fatigue severity, older age, and female gender. All predictors were unrelated to psychological distress apart from weak positive associations with physical fatigue and symptom frequency. Results identify a potent set of predictors of HRQoL and show that CFS has a pervasive negative impact on quality of life, particularly physical and psychological functioning.     

Ethical implications of implantable radiofrequency identification (RFID) tags in humans

This article reviews the use of implantable radiofrequency identification (RFID) tags in humans, focusing on the VeriChip (VeriChip Corporation, Delray Beach, FL) and the associated VeriMed patient identification system. In addition, various nonmedical applications for implanted RFID tags in humans have been proposed. The technology offers important health and nonhealth benefits, but raises ethical concerns, including privacy and the potential for coercive implantation of RFID tags in individuals. A national discussion is needed to identify the limits of acceptable use of implantable RFID tags in humans before their use becomes widespread and it becomes too late to prevent misuse of this useful but ethically problematic technology.     

An inexpensive infrared detector to verify the delivery of food pellets

The reproducibility of experimental outcomes depends on consistent control of independent variables. In food-maintained operant performance, it is of utmost importance that the quantity of food delivered is reliable. To that end, some commercial food pellet dispensers have add-on attachments to sense the delivery of pellets. Not all companies, however, offer such add-ons. Aside from availability, cost and temporary reduction in throughput may be a problem for smaller labs. The present paper outlines our recent development of a simple, inexpensive infrared device to detect and confirm the delivery of pellets. The in-line construction of the detector routes the falling pellet through a barrel so that it passes between an infrared emitter and receiver. The circuitry was designed to be compatible with all commercially available behavioral measurement systems, and so may be retrofit to any existing system. Our tests with the detector so far have shown that it is 100% accurate in detecting pellet delivery. The individual unit cost is approximately 25 dollars. The low cost and versatility of the device offer an easy method to ensure the integrity of food delivery in operant settings.     

On that peculiar practice of promising

T. M. Scanlon has alleged that the social practice of promising fails to capture the sense in which when I break my promise I have wronged the promisee in particular. I suggest the practice of promising requires the promisee to have a normatively significant status, a status with interpersonal authority with respect to the promisor, and so be at risk of a particular harm made possible by the social practice of promising. This formulation of the social practice account avoids Scanlon’s concern without collapsing into what Elinor Mason has recently referred to as deflationism about promising.

The effects of different intensity levels of background noise on dichotic listening to consonant-vowel syllables

It has previously been shown that the right ear advantage in dichotic listening to consonant-vowel syllables is affected if a background noise is presented at the same time as the dichotic stimuli. What is not known is, however, if there is also an effect of varying the intensity level of the background noise. We therefore presented conversation or traffic noise background noise simultaneously with the dichotic syllable stimuli to healthy adult subjects. The intensity of the background noises varied between 50-65 dB in steps of 5 dB. The results showed that the right ear correct reports decreased, while left ear correct reports increased as a consequence of increasing background noise intensity. The effects were also stronger for the right ear, and for the traffic background noise condition, particularly at the two highest intensity levels. The results are discussed in terms of alertness and attentional mechanisms.
