Selected AbstractsIndividual differences in preschool children: temperament or personality?INFANT AND CHILD DEVELOPMENT, Issue 3 2010Cathy L. Grist Abstract Individual differences among adults have generally been conceptualized in terms of personality theory and traits. In contrast, individual differences among very young children (birth to kindergarten) have generally been conceptualized in terms of temperament theory and traits. The present study compares and contrasts measures of temperament and personality in a sample of preschool children. Temperament traits were assessed with a well-established measure (the Rothbart CBQ), and a new preschool rating instrument was used to assess personality traits from the five-factor framework (M5-PS). Indeed, a key purpose of this study was to further the development of the M5-PS. Data were gathered on 122 preschool children who were rated by their teachers. Significant correlations were found between the temperament trait Surgency and the personality trait Extraversion, between the temperament trait Negative Affect and the personality trait Neuroticism, and between the temperament trait Effortful Control and the personality trait Conscientiousness. The overall pattern of correlational data suggests that individual differences in preschool children can be adequately described using the five-factor theory, and that this framework may effectively subsume traditional theories of temperament. Preliminary support for the reliability and validity of the M5-PS is offered. Copyright © 2010 John Wiley & Sons, Ltd. [source] Career communities: a preliminary exploration of member-defined career support structuresJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 4 2004Polly Parker This paper explores the concept of career communities: social structures that provide career support and frequently transcend the boundaries of any single organization. The theoretical background notes the convergence of a number of different perspectives from both career development and organization studies, pertaining to the social contextualization of careers. The methodology involved eliciting expressions of the (individual) subjective career from the members of three potential career communities, and then exploring (communal) inter-subjective interpretations in focus groups. Our results suggest that career communities typically involve a hybrid of types rather than any one pure type. Preliminary support is found for the view that career communities facilitate career support, sensemaking and learning. The results invite further research into career communities and have implications for organizational behavior and human resource management, suggesting greater appreciation of the extra-organizational as well as intra-organizational communities in which careers develop.

[source] The Sensitivity of Continuous Laboratory Measures of Physiological and Subjective Sexual Arousal for Diagnosing Women with Sexual Arousal DisorderTHE JOURNAL OF SEXUAL MEDICINE, Issue 2pt2 2010Cindy M. Meston PhD ABSTRACT Introduction., Past findings on the diagnostic sensitivity of vaginal photoplethysmography are limited by testing among women with heterogeneous sexual dysfunctions and by the use of statistical techniques that are unable to assess how changes in subjective arousal are associated with changes in physiological arousal. Aims., The aims of this study were to: (i) test the sensitivity of vaginal photoplethysmography and continuous measures of subjective sexual arousal in differentiating between women with and without sexual arousal or orgasm dysfunction; and (ii) examine the diagnostic utility of measuring the synchrony between genital and subjective sexual responses. Methods., Sexual arousal was assessed in sexually healthy women (n = 12), women with orgasm disorder (OD; n = 12), and 38 women who met the criteria for the three subcategories of sexual arousal dysfunction described by Basson et al. (i.e., genital sexual arousal disorder [GAD; n = 9], subjective sexual arousal disorder [SAD; n = 13], and combined genital and subjective arousal disorder [CAD; n = 16]). Main Outcome Measures., Physiological sexual arousal was assessed using vaginal photoplethysmography, and subjective sexual arousal was measured continuously and using a Likert-scale in response to sexual videos. Results., Women with GAD showed the lowest and women with CAD showed the highest levels of vaginal pulse amplitude response to erotic stimuli. Women with sexual arousal disorder showed significantly lower levels of subjective sexual arousal to erotic stimuli than did sexually healthy women. Relations between subjective and physiological measures of sexual arousal were significantly weaker among women with sexual arousal disorder than sexually healthy women or women with OD. Conclusion., Preliminary support was provided for the diagnostic utility of measuring the synchrony between subjective and genital arousal in women with sexual arousal disorder. Findings do not support the sensitivity of using vaginal photoplethysmography, or continuous or Likert-scale measures of subjective arousal for differentiating between subtypes of women with sexual arousal disorder.

[source] Connections between species diversity and genetic diversityECOLOGY LETTERS, Issue 7 2005Mark Vellend Abstract Species diversity and genetic diversity remain the nearly exclusive domains of community ecology and population genetics, respectively, despite repeated recognition in the literature over the past 30 years of close parallels between these two levels of diversity. Species diversity within communities and genetic diversity within populations are hypothesized to co-vary in space or time because of locality characteristics that influence the two levels of diversity via parallel processes, or because of direct effects of one level of diversity on the other via several different mechanisms. Here, we draw on a wide range of studies in ecology and evolution to examine the theoretical underpinnings of these hypotheses, review relevant empirical literature, and outline an agenda for future research. The plausibility of species diversity,genetic diversity relationships is supported by a variety of theoretical and empirical studies, and several recent studies provide direct, though preliminary support. Focusing on potential connections between species diversity and genetic diversity complements other approaches to synthesis at the ecology,evolution interface, and should contribute to conceptual unification of biodiversity research at the levels of genes and species. [source] The neglected constituent of the basal forebrain corticopetal projection system: GABAergic projectionsEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 12 2002Martin Sarter Abstract At least half of the basal forebrain neurons which project to the cortex are GABAergic. Whilst hypotheses about the attentional functions mediated by the cholinergic component of this corticopetal projection system have been substantiated in recent years, knowledge about the functional contributions of its GABAergic branch has remained extremely scarce. The possibility that basal forebrain GABAergic neurons that project to the cortex are selectively contacted by corticofugal projections suggests that the functions of the GABAergic branch can be conceptualized in terms of mediating executive aspects of cognitive performance, including the switching between multiple input sources and response rules. Such speculations gain preliminary support from the effects of excitotoxic lesions that preferentially, but not selectively, target the noncholinergic component of the basal forebrain corticopetal system, on performance in tasks involving demands on cognitive flexibility. Progress in understanding the cognitive functions of the basal forebrain system depends on evidence regarding its main noncholinergic components, and the generation of such evidence is contingent on the development of methods to manipulate and monitor selectively the activity of the GABAergic corticopetal projections.

Greenslade Abstract Title.,Distinguishing between task and contextual performance for nurses: development of a job performance scale Aim., This paper is a report of a development and validation of a new job performance scale based on an established job performance model. Background., Previous measures of nursing quality are atheoretical and fail to incorporate the complete range of behaviours performed. Thus, an up-to-date measure of job performance is required for assessing nursing quality. Methods., Test construction involved systematic generation of test items using focus groups, a literature review, and an expert review of test items. A pilot study was conducted to determine the multidimensional nature of the taxonomy and its psychometric properties. All data were collected in 2005. Findings., The final version of the nursing performance taxonomy included 41 behaviours across eight dimensions of job performance. Results from preliminary psychometric investigations suggest that the nursing performance scale has good internal consistency, good convergent validity and good criterion validity. Conclusion., The findings give preliminary support for a new job performance scale as a reliable and valid tool for assessing nursing quality. However, further research using a larger sample and nurses from a broader geographical region is required to cross-validate the measure. This scale may be used to guide hospital managers regarding the quality of nursing care within units and to guide future research in the area. [source] A meta-analysis of the effects of internet- and computer-based cognitive-behavioral treatments for anxietyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 1 2009Mark A. Reger Abstract Internet-and computer-based cognitive-behavioral treatments have been introduced as novel approaches to deliver standard, quality treatment that may reduce barriers to care. The purpose of this review is to quantitatively summarize the literature examining the treatment effects of Internet- or computer-based treatment (ICT) on anxiety. Nineteen randomized controlled ICT trials were identified and subjected to fixed and random effects meta-analytic techniques. Weighted mean effect sizes (Cohen's d) showed that ICT was superior to waitlist and placebo assignment across outcome measures (ds=.49,1.14). The effects of ICT also were equal to therapist-delivered treatment across anxiety disorders. However, conclusions were limited by small sample sizes, the rare use of placebo controls, and other methodological problems. In addition, the number of available studies limited the opportunity to conduct analyses by diagnostic group; there was preliminary support for the use of ICT for panic disorder and phobia. Large, well-designed, placebo-controlled trials are needed to confirm and extend the results of this meta-analysis. © 2008 Wiley Periodicals, Inc. J Clin Psychol 65: 1,21, 2009. [source] Effect of oral melatonin on the procoagulant response to acute psychosocial stress in healthy men: a randomized placebo-controlled studyJOURNAL OF PINEAL RESEARCH, Issue 4 2008Petra H. Wirtz Abstract:, Acute mental stress is a potent trigger of acute coronary syndromes. Catecholamine-induced hypercoagulability with acute stress contributes to thrombus growth after coronary plaque rupture. Melatonin may diminish catecholamine activity. We hypothesized that melatonin mitigates the acute procoagulant stress response and that this effect is accompanied by a decrease in the stress-induced catecholamine surge. Forty-five healthy young men received a single oral dose of either 3 mg melatonin (n = 24) or placebo medication (n = 21). One hour thereafter, they underwent a standardized short-term psychosocial stressor. Plasma levels of clotting factor VII activity (FVII:C), FVIII:C, fibrinogen, D-dimer, and catecholamines were measured at rest, immediately after stress, and 20 min and 60 min post-stress. The integrated change in D-dimer levels from rest to 60 min post-stress differed between medication groups controlling for demographic and metabolic factors (P = 0.047, = 0.195). Compared with the melatonin group, the placebo group showed a greater increase in absolute D-dimer levels from rest to immediately post-stress (P = 0.13; = 0.060) and significant recovery of D-dimer levels from immediately post-stress to 60 min thereafter (P = 0.007; = 0.174). Stress-induced changes in FVII:C, FVIII:C, fibrinogen, and catecholamines did not significantly differ between groups. Oral melatonin attenuated the stress-induced elevation in the sensitive coagulation activation marker D-dimer without affecting catecholamine activity. The finding provides preliminary support for a protective effect of melatonin in reducing the atherothrombotic risk with acute mental stress. [source] Testing an empirically derived mental health training model featuring small groups, distributed practice and patient discussionMEDICAL EDUCATION, Issue 2 2009Rachael C Murrihy Objectives, Internationally, family doctors seeking to enhance their skills in evidence-based mental health treatment are attending brief training workshops, despite clear evidence in the literature that short-term, massed formats are not likely to improve skills in this complex area. Reviews of the educational literature suggest that an optimal model of training would incorporate distributed practice techniques; repeated practice over a lengthy time period, small-group interactive learning, mentoring relationships, skills-based training and an ongoing discussion of actual patients. This study investigates the potential role of group-based training incorporating multiple aspects of good pedagogy for training doctors in basic competencies in brief cognitive behaviour therapy (BCBT). Methods, Six groups of family doctors (n = 32) completed eight 2-hour sessions of BCBT group training over a 6-month period. A baseline control design was utilised with pre- and post-training measures of doctors' BCBT skills, knowledge and engagement in BCBT treatment. Results, Family doctors' knowledge, skills in and actual use of BCBT with patients improved significantly over the course of training compared with the control period. Conclusions, This research demonstrates preliminary support for the efficacy of an empirically derived group training model for family doctors. Brief CBT group-based training could prove to be an effective and viable model for future doctor training. [source] Surgical skills training: simulation and multimedia combinedMEDICAL EDUCATION, Issue 9 2001Roger Kneebone Context Basic surgical skills are needed throughout the medical profession, but current training is haphazard and unpredictable. There is increasing pressure to provide transparency about training and performance standards. There is a clear need for inexperienced learners to build a framework of basic skills before carrying out surgical procedures on patients. Effective learning of a skill requires sustained deliberate practice within a cognitive framework, and simulation offers an opportunity for safe preparation. Objectives This paper presents a new approach to basic surgical skills training, where tuition using a specially designed computer program is combined with structured practice using simulated tissue models. This approach to teaching has evolved from practical experience with surgical skills training in workshops. Methods Pilot studies with 72 first-year medical students highlighted the need for separate programs for teaching and for self-directed learning. The authors developed a training approach in the light of this experience. Subsequent in-depth observational and interview studies examined (a) individual teaching sessions between surgical teachers and learners (five consultant surgeons and five senior house officers) and (b) group teaching sessions with general practitioners (14 participants in three group interviews). Further work has resulted in a self-directed learning program. Conclusions Qualitative analysis of observational and interview data provides strong preliminary support for the effectiveness of this approach. The response of teachers and learners was extremely positive. The combination of information (presented by computer) and practice of psychomotor skill (using simulated tissue models) could be extended to other surgical and practical skills. [source] Goal attainment for spasticity management using botulinum toxinPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 1 2006Stephen Ashford Abstract Background and Purpose. To determine whether goal attainment scaling (GAS) can demonstrate functional gains following injection of botulinum toxin (BTX) for spasticity in severely disabled patients. Method. Subjects were categorized as ,responder' (positive clinical outcome) and ,non-responder' (non-significant clinical outcome) on the basis of their overall clinical response. GAS scores for functional goals were calculated retrospectively and compared with standard outcome assessments undertaken at the time of intervention. Integrated care pathway (ICP) proformas were interrogated for 18 patients with acquired brain injuries. Mean age was 44.4 (SD 13.4) years. Results. Baseline GAS and Barthel scores were similar for the responder and non-responder groups. The outcome GAS score was significantly greater in the responder than in the non-responder group (Mann,Whitney U = 11.0; p = 0.011) as was the change in GAS score (Mann,Whitney U = 8.0; p = 0.004). GAS scores reflected change recorded in focal outcome measures. However, the Barthel Index measured change in only one case. Conclusions. This exploratory retrospective study provides preliminary support for the hypothesis that GAS provides a useful measure of functional gains in response to treatment with BTX, and is more sensitive than global measures such as the Barthel Index.

[source] Case Management Relationships and a Recovery Orientation: A Consumer Survey of Class Members in the Arnold CaseAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 3 2010José B. Ashford The purpose of this study was to examine the relative contributions of the working alliance in predicting a recovery orientation. An additional aim was to determine whether a measure of case management fairness contributed any additional proportion of explained variance in a recovery orientation beyond what is accounted for by the working alliance. The study blended structured interview and clinical judgment measures with survey research methods to obtain data about consumer relationships with their case managers, as well as their recovery attitudes. The sample consisted of (N = 167) priority-class members involved in the Arnold v. Arizona Department of Health Services class-action lawsuit in Maricopa County, Arizona. The results showed that the working alliance and case management fairness variables accounted for more of the explained variance in a recovery orientation, than any of the other known correlates of recovery. The results also provided some preliminary support for the inclusion of case management fairness as a predictor variable of a recovery orientation, in that the study's measure of case management fairness contributed a small proportion of additional variance beyond what was explained by the working alliance in predicting a dimension of a recovery orientation. The implications of the study's findings for practice and future research are discussed. [source] Effects of participation in a martial arts,based antibullying program in elementary schools,PSYCHOLOGY IN THE SCHOOLS, Issue 10 2008Stuart W. Twemlow This study evaluated the Gentle Warrior Program, a traditional martial arts,based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results indicated that boys who participated in more Gentle Warrior sessions reported a lower frequency of aggression and greater frequency of helpful bystanding (i.e., helpful behavior toward victims of bullying) over time, relative to boys with less frequent participation. The effect of participation on aggression was partially mediated by empathy. The effect of participation on helpful bystanding was fully mediated by changes in student empathy. No significant results were found for girls. Results of the study provide preliminary support for the use of martial arts,based interventions to address bullying in schools for boys, by teaching empathy, self-control, and peaceful strategies to resolve conflicts. © 2008 Wiley Periodicals, Inc. [source] Before There Was Enron, There Was Orange County: A Study of Local Government Financial-Oversight CommitteesPUBLIC BUDGETING AND FINANCE, Issue 3 2010DAVID S. T. MATKIN Recent financial scandals in some of America's largest corporations have prompted popular speculation that a similar crisis may occur within the public sector and, therefore, that government and nonprofit organizations should be required to adopt financial oversight practices similar to those that are mandated of publicly-traded corporations in the Sarbanes-Oxley Act of 2002. One of those mandated practices,the use of financial-oversight committees,is already a common practice in public organizations, though little is known about its effectiveness. This study uses a national sample of local governments to examine whether financial-oversight committees improve financial control and strengthen stakeholder confidence in financial reporting. The findings provide preliminary support for the use of financial-oversight committees as an effective tool to improve financial accountability in local government. [source] Outcome Effectiveness of Community Health Workers: An Integrative Literature ReviewPUBLIC HEALTH NURSING, Issue 1 2002Susan M. Swider Ph.D. Community health workers (CHWs) are promoted as a mechanism to increase community involvement in health promotion efforts, despite little consensus about the role and its effectiveness. This article reviews the databased literature on CHW effectiveness, which indicates preliminary support for CHWs in increasing access to care, particularly in underserved populations. There are a smaller number of studies documenting outcomes in the areas of increased health knowledge, improved health status outcomes, and behavioral changes, with inconclusive results. Although CHWs show some promise as an intervention, the role can be doomed by overly high expectations, lack of a clear focus, and lack of documentation. Further research is required with an emphasis on stronger study design, documentation of CHW activities, and carefully defined target populations. [source] Changes in yearling rhesus monkeys' relationships with their mothers after sibling birthAMERICAN JOURNAL OF PRIMATOLOGY, Issue 4 2001B.J. Devinney Abstract The birth of a new sibling is believed to signify an abrupt and important transition in a young primate's relationship with its mother,one that is of potential importance from at least three theoretical perspectives: attachment theory, parent,offspring conflict theory, and dynamic assessment models. This study examines changes in relationships between free-ranging yearling rhesus monkeys (Macaca mulatta) and their mothers concomitant with the birth of the mother's next infant, and tests predictions derived from each theoretical perspective. We observed 31 yearling rhesus on Cayo Santiago, Puerto Rico, 3 months before and 3 months after their siblings' births, using focal animal sampling methods. Changes in measures related to mother,yearling interaction and yearling distress were examined using repeated-measures analysis of variance. After sibling birth, mothers and yearlings abruptly reduced amounts of time in contact and increased amounts of time at a distance and out of sight of one another. Mothers and yearlings played approximately equal roles in bringing about decreases in proximity, and yearlings took the primary roles in bringing about decreases in contact. Rates of maternal aggression toward yearlings increased immediately and markedly after birth, possibly providing yearlings with early cues regarding subsequent decreased levels of maternal care. There were no marked increases in overt signs of yearling distress (e.g., vocalizations or tantrums) following the births. We conclude that yearlings generally acquiesced to reduced levels of care, responding behaviorally with increased independence and maturity. In this sense, our study provides preliminary support for dynamic assessment models over attachment theory and parent,offspring conflict theory models. Am. J.

[source] Moderate Physical Activity and Its Relationship to Select Measures of a Healthy DietTHE JOURNAL OF RURAL HEALTH, Issue 2 2004Frank Blakely MS ABSTRACT: Context: In rural communities, physical activity may influence and predict nutritional behaviors. Purpose: The purpose of this investigation was to determine if an individual's stage of participation in moderate physical activity was related to select measures of a healthy diet. Methods: Data were collected using a mail-in survey from a random sample conducted in the rural/frontier communities of Idaho, Montana, and Wyoming. A total of 6 communities, 2 from each state, were surveyed with approximately 575 surveys sent to each community. The response rate was 51.5%. Findings: Regression analysis revealed that there was a significant difference (P<.05) in select measures of a healthy diet between those in the maintenance stage of moderate levels of physical activity (physically active for 6 months or more) and those in precontemplation (not currently active and with no intention of starting), contemplation (not currently active but considering starting within the next 6 months), and preparation (not currently active but taking steps to become active within the next 30 days). Those in maintenance had a healthier diet. Additionally, women, older people, those with at least some college education, and those who were employed had healthier diets. Conclusions: These results lend preliminary support to the idea that moderate physical activity could act as a gateway behavior, a behavior that, if adopted, could lead to the adoption of other healthy behaviors. However, additional research is needed to confirm the nature, if any, of this relationship. [source] | |||||||||||||||||||
