Predicting exposure to and liking of media violence: a uses and gratifications approach

The current study examined the interpersonal coordination of nonverbal immediacy behaviors in the emotional support process. Participants (N = 216) disclosed a distressing event to a confederate who was trained to exhibit emotional support that varied in high, moderate, or low nonverbal immediacy. After the 5-minute conversation, participants evaluated the confederate on several scales. Trained coders coded 10 immediacy cues of confederates and participants. Results indicated that participants tended to match confederates, regardless of the immediacy condition. Perceived liking for the helper did not moderate immediacy matching and exerted only a main effect on confederate immediacy; participants reported liking better highly immediate helpers than either moderately immediate or nonimmediate helpers. The study also generated several sex differences, such that, with the exception of eye contact, women tended to match confederates more than did men.     

Endothelins -- clinical perspectives

Endothelins (ET) are a group of endogenous peptides, which have a strong and long-lasting vasoconstrictive effect. Three isoforms of endothelins coded by three different genes have been identified to date. Endothelin-1 (ET-1) is the most potent vasoconstrictive agent currently identified, and it was originally isolated and characterized from the culture media of aortic endothelial cells. Two other isoforms, named endothelin-2 (ET-2) and endothelin-3 (ET-3), were subsequently identified, along with structural homologues isolated from the venom ofActractapis engaddensis known as the sarafotoxins. The biological effects of endothelin production are determined via activation of one or two G-protein coupled receptors, endothelin receptors A (ETRA) and B (ETRB1 and ETRB2). Recently endothelin receptor C (ETRC) was discovered, however, its functions and distribution still remain unclear. The effects mediated by ET-1 via ETRA are vasoconstriction, bronchoconstriction and secretion of aldosterone. Agonists related to the ETRB1 activation cause vasodilatation by stimulating NO, PGI2 and endothelium-derived hyperpolarizing factor (EDHF). In contrast, coupling to ETRB2 causes vasoconstriction. Involvement of ET has been demonstrated in the pathophysiology of certain disorders. In this review, we discuss the physiological and pathophysiological role of endothelium-derived ET-1, the pharmacology of its two receptors, focusing on the role of ET-1 in the development of some pathophysiological conditions.     

A conceptual approach for blended leadership for tertiary education institutions

Over the last 20 years, the tertiary education sector has adopted new administrative management approaches, with the aim of improving accountable and strategic focus. Over the same period, the question of how to build leadership capacity to improve learning and teaching and research outcomes has led to discussion on what constitutes academic leadership. While both these advances are needed, what is missing is integration between the two such that academics and professional staff are engaged collaboratively to achieve learning and teaching and research outcomes that are accountable within a strategic focus. This article builds on research into the use of distributed leadership to build leadership for learning and teaching that resulted in the design of a conceptual framework for distributed leadership. Based on this conceptual framework, it proposes a conceptual blended leadership approach to engage academics and professional staff working in collaboration.     

Reminiscence,Psychological Well-Being,and Ego Integrity in Portuguese Elderly People

This paper analyzes the impact of a reminiscence program on the psychological well-being and ego integrity of elderly people with depressive symptomatology. Ninety people aged 65 and over participated in a quasi-experimental design with pretest and posttest evaluations. They were assigned to one of three groups: (a) experimental group (reminiscence sessions); (b) control group or (c) control-placebo group (weekly relaxation sessions). The results indicate that only the experimental group had significant increases in its overall psychological well-being and ego integrity. This suggests that the promotion of instrumental and integrative reminiscences is an important therapeutic tool for psychological well-being in elderly people with depressive symptomatology.

Time to participate: Lessons from the literature for learning and teaching project evaluation in higher education

Evaluation plays an increasingly important role in the quality-driven context of higher education. Projects that focus on learning and teaching often have evaluation expected of them, however, there is little evidence on the effectiveness of approaches nor the extent to which the praxis of evaluation is achieved. To illustrate this phenomenon, project funding and evaluation expectations are reviewed and the resulting analysis of the literature identifies eight emergent themes. Two overarching factors that unite these themes are time (or lack of it) and participation, leading to six issues for evaluation practice. Alignment of evaluation theory with practice requires focused attention if the maximum benefits of evaluation for the project processes are to be achieved.     

Narrative Fiction and Expository Nonfiction Differentially Predict Verbal Ability

Although reading is known to be an important contributor to language abilities, it is not yet well established whether different text genres are uniquely associated with verbal abilities. We examined how exposure to narrative fiction and expository nonfiction predict language ability among university students. Exposure was measured both with self-report and with recognition tests of print exposure. Verbal ability was measured in the form of synonym knowledge, analogies, sentence completion, and reading comprehension in 4 different studies. Across all studies, narrative fiction was a better predictor of verbal abilities relative to expository nonfiction. When examining unique associations, controlling for demographic variables and the other genre, fiction remained a robust predictor, whereas nonfiction became a null or weak negative predictor. In light of this evidence, it appears that what we read plays an important role in how reading contributes to language development.     

The roles of perceived parental expectation and criticism in adolescents’ multidimensional perfectionism and achievement goals

Perfectionism consists of personal predispositions and attitudes toward performance. Although there is some disagreement in the field regarding how to best define and measure perfectionism, most studies have supported a distinction between adaptive and maladaptive perfectionism. The current study examines a model in which students’ perceptions of parents’ standards and criticism are proposed as antecedents of multidimensional perfectionism, which in turn are hypothesised to be associated with types of academic achievement goal orientations. The sample consisted of 256 high school students who completed questionnaires assessing adaptive and maladaptive perfectionism, perceptions of their parents and personal achievement goals. Structural equation modelling supported the hypotheses suggesting that high parental standards are positively associated with the adaptive perfectionist characteristic of self-organised perception, which in turn are associated with a mastery goal orientation. Parental criticism predicted the maladaptive perfectionist characteristic of concern over mistakes, which in turn was found associated with a performance-avoidance goal orientation.
