Forgivingness, relationship quality, stress while imagining relationship events, and physical and mental health.

Abstract: In all, 39 participants (19 male, 20 female) were classified as either happy (n = 19) or unhappy (n = 20) with a relationship. Baseline salivary cortisol was measured. Participants imagined (for a 5-min duration) scenes typical of their relationship, and salivary cortisol was measured again. Participants in unhappy relationships had higher cortisol reactivity (indicating higher stress) following the imagery. Cortisol reactivity was predicted by relationship variables (high love and liking for the partner, high happiness with the relationship) and personality variables (high forgivingness, low trait anger). Personality had an indirect effect through the relationship variables. Physical health was predicted by personality variables. Mental health was predicted by both personality and relationship variables. Implications of these results for counseling health psychology are discussed.

Single nucleotide polymorphism genotyping: biochemistry, protocol, cost and throughput.

Abstract: The large number of single nucleotide polymorphism (SNP) markers available in the public databases makes studies of association and fine mapping of disease loci very practical. To provide information for researchers who do not follow SNP genotyping technologies but need to use them for their research, we review here recent developments in the fields. We start with a general description of SNP typing protocols and follow this with a summary of current methods for each step of the protocol and point out the unique features and weaknesses of these techniques as well as comparing the cost and throughput structures of the technologies. Finally, we describe some popular techniques and the applications that are suitable for these techniques.

Empathy and the emergence of task and relations leaders

Abstract: This empirical study of small workgroup peers investigated relationships among perceptions of emotional abilities (i.e., empathy, ability to identify others' emotions, and ability to express one's own emotions), cognitive abilities, and leadership emergence. While controlling for cognitive ability and complex task performance, we found that people rated highly on empathy garnered attributions of leadership from their peers. Our study found that an actor's empathy (1) related positively to ratings of task leadership and ratings of relations leadership and (2) mediated the effect of other emotional abilities (i.e., the ability to identify others' emotions and the ability to express one's own emotions) on task and relations leadership. Emotional abilities were unrelated to cognitive abilities or complex task performance. Cognitive abilities and complex task performance earned actors higher ratings on task leadership, but not on relations leadership. The article concludes by relating the results to the new research on authentic leadership.

Examination of static and dynamic postural stability in individuals with functionally stable and unstable ankles.

Abstract: OBJECTIVE To determine static and dynamic postural stability differences between functional ankle instability and stable ankle groups. DESIGN Subjects were required to balance on a single leg and remain motionless for 20 seconds. After completing 3 trials, they performed a jump-landing test, which required them to jump 50% to 55% of their maximum vertical jump height. They landed on a single leg, stabilized quickly, and remained motionless for 20 seconds. SETTING Sports Medicine Research Laboratory. PARTICIPANTS Subjects with functional ankle instability (n = 14) who reported at least 2 sprains and "giving way" sensations at their ankle joint within the year prior to testing. Fourteen subjects with no history of ankle sprain injury were matched to subjects with functional ankle instability. MAIN OUTCOME MEASURES Anterior/posterior and medial/lateral mean sway quantified static postural stability during single-leg stance. Dynamic postural stability was quantified with anterior/posterior and medial/lateral time to stabilization during single-leg jump landing. RESULTS Mean sway was not significantly different between groups in the anterior/posterior (P = 0.28) and medial/lateral (P = 0.65) directions. The functional ankle instability group took significantly longer to stabilize in the anterior/posterior (3.27 +/- 0.72 seconds vs. 2.33 +/- 0.33 seconds; P < 0.001) and medial/lateral (2.48 +/- 0.50 seconds vs. 2.00 +/- 0.65 seconds; P = 0.04) directions. CONCLUSIONS Individuals with functional ankle instability took significantly longer to stabilize than individuals with stable ankles after a single-leg jump landing. Differences between groups were not detected with mean sway measured during single-leg stance.
