I get by with a little help from my friends: Examining the peer context of satisfaction with casual sexual relationships and experiences

We examined the role of peers in understanding satisfaction with casual sexual relationships and experiences (CSREs) in young adulthood. Specifically, we examined how perception of peer CSRE engagement, communication with peers about CSREs and peer approval of CSRE engagement were associated with satisfaction both immediately following CSRE engagement and one month after the CSRE occurred. Participants from non-college and college samples completed an online battery of questionnaires at two time points surrounding a high alcohol-consumption event in the USA: Halloween. Path analysis results indicated that peer approval was positively associated with later satisfaction, but only for those in college. Additionally, intentions to communicate with peers were positively associated with satisfaction a month following CSRE, but only for those who engaged in non-penetrative sex. None of the tested associations was qualified by gender.     

Ethics Consultation in Pediatrics: Long-Term Experience From a Pediatric Oncology Center

There is little information about the content of ethics consultations (EC) in pediatrics. We sought to describe the reasons for consultation and ethical principles addressed during EC in pediatrics through retrospective review and directed content analysis of EC records (2000–2011) at St. Jude Children's Research Hospital. Patient-based EC were highly complex and often involved evaluation of parental decision making, particularly consideration of the risks and benefits of a proposed medical intervention, and the physician's fiduciary responsibility to the patient. Nonpatient consultations provided guidance in the development of institutional policies that would broadly affect patients and families. This is one of the few existing reviews of the content of pediatric EC and indicates that the distribution of ethical issues and reasons for moral distress are different than with adults. Pediatric EC often facilitates complex decision making among multiple stakeholders, and further prospective research is needed on the role of ethics consultation in pediatrics.     

Personality Characteristics of BASE Jumpers

BASE jumping is an extreme sport, which is associated with significant risk of injury and death. We aimed to determine whether BASE jumpers have different personality characteristics to an age-matched, normal control population. An international population of BASE jumpers was examined using the Temperament and Character Inventory (TCI). Mean age was thirty-four years; fifty-nine (87%) jumpers were male; twenty-eight (41%) jumpers had sustained a significant injury. A substantial proportion of the BASE jumpers presented extremely low scores in the temperament measure of Harm Avoidance (p < 0.001); the extent of which has not been reported in any other population.     

Sport-Specific Practice and the Development of Expert Decision-Making in Team Ball Sports

The role of sport-specific practice in the development of decision-making expertise in the sports of field hockey, netball, and basketball was examined. Fifteen expert decision-makers and 13 experienced non-expert athletes provided detailed information about the quantity and type of sport-specific and other related practice activities they had undertaken throughout their careers. Experts accumulated more hours of sport-specific practice from the age of 12 years onwards than did non-experts, spending on average some 13 years and 4,000 hours on concentrated sport-specific practice before reaching international standard. A significant negative correlation existed between the number of additional activities undertaken and the hours of sport-specific training required before attaining expertise, suggesting a functional role for activities other than sport-specific training in the development of expert decision-making.     

Edge-induced illusory contours and visual detection: Subthreshold summation or spatial cueing?

Findings that illusory contours can facilitate visual detection of a subthreshold real line (Dresp & Bonnet, 1995) were not replicated, when line-induced instead of edge-induced illusory contour stimuli were used (Salvano-Pardieu et al., 2006). Rather, the results of the latter study supported the importance of spatial cues. The present study was designed to investigate whether spatial cueing might also facilitate detection of targets superimposed on edge-induced illusory contours. In Experiment 1, a target line was superimposed on the illusory contour of a Kanizsa square, presented between dots with a precise or distant location to the target, or on a homogeneous field (control). Detection of the target was poorest for the control, followed by the distant-dots and Kanizsa conditions, whereas it was best for precisely cueing dots. Experiment 2 replicated the conditions in Experiment 1 (Kanizsa, precisely cueing dots, and control) with additional controls for possible luminance effects. The two new conditions matched the Kanizsa condition for overall luminance and preciseness of spatial cueing without generating illusory contours. Performance was best in the dot condition and worst in the control, but the same across the Kanizsa and matched luminance conditions. In Experiments 3 and 4, the stimuli presented were matched more closely to those used by Dresp and Bonnet, but still the results confirmed those obtained in our Experiments 1 and 2. Together, these experiments strongly suggest that detection is also facilitated by spatial cueing rather than subthreshold summation, in the case of edge-induced illusory contours.     

Combining Methodologies in the Construct Validation Process: An Empirical Illustration

Confirmatory Factor Analysis (CFA) has received considerable support as a methodology for assessing construct validity. As with other methodologies, however, numerous problems can be encountered when using CFA to assess construct validity. Given the limitations of the CFA, Multitrait-Multimethod (MTMM), and analysis of variance (ANOVA) methodologies, a set of guidelines was developed. The guidelines recommend that the characteristics of the data set be used to determine how the three alternative construct validation methodologies can be used in combination. Examples from the research literature are discussed in order to demonstrate the application of these guidelines.     

Automated Assessment of Reasons For Joining an Organization

An automated instrument capable of identifying and rank ordering reasons for joining the United States Marine Corps was developed and administered to a sample of 150 men. Testing time ranged from slightly less than 3 min to 5 1/2 min. Because of its ease of administration and effectiveness in identifying motivators, the automated instrument holds significant potential for use in a variety of settings in which personal characteristics (e.g., preferences, choice criteria, values, etc.) must be rapidly identified.
