Voluntary manual exploration and vision in rod bisection

Two experiments were carried out to investigate contributions of voluntary manual exploration and vision to rod-bisection performance when the rod was placed in different spatial positions. Analysis showed both voluntary manual exploration and vision contributed to the accuracy of rod-bisection performance in healthy adults (Exp. 1: 12 men, 13 women; Exp. 2: 10 men, 11 women). Advantages of voluntary manual exploration were related to rod position and initial search direction. Results are discussed with regard to ecological approach to action and perception, two cortical systems (ventral and dorsal streams) for perception and control of actions, and the hemispheric activation hypothesis.     

The Relationship Between Machiavellianism and Knowledge Sharing Willingness

Knowledge sharing has become a legitimate and important organizational activity. Over the last two decades, firms have become creative in their efforts to make knowledge sharing take place. Meanwhile, Machiavellian orientation has been regarded as one of the most important variables in the study of management and organizational behavior for the last three decades. However, the existing literature does not offer any measure of relationships between Machiavellianism and knowledge sharing willingness. Therefore, this research aims to explore the relationship between Machiavellianism and knowledge sharing willingness. With a total of 325 valid questionnaires completed by employees, the paper presents some conclusive and valuable suggestions for businesses and scholars alike.     

A 1-year follow-up of an experimental study of a self-management arthritis programme with an added exercise component of clients with osteoarthritis of the knee

The aim was to assess the self-efficacy and health outcomes of an adopted Arthritis Self-Management Programme (ASMP) among osteoarthritic knee sufferers in Hong Kong at 1 year. An experimental study with 95 participants assigned randomly to the intervention (n=45) or control group (n=50). Seventy-seven (81.1%) participants joined at least one out of three follow-ups in the 12 month period. Participants in the intervention group received a 6-week ASMP with an added exercise component in two general clinics. Outcome measures included arthritis self-efficacy (ASE) and health outcomes including pain and fatigue rating, self-rated health, daily activities limitation and number of unplanned arthritis-related medical consultations. Mean change (12 months minus baseline) and the effect size of the outcome measures were calculated by Mann-Whitney U test and nQuery Advisor 4.0. At 12 months, there were significant reductions of current pain (p=0.0001), pain at night (p=0.001), pain during walking (p=0.01) and number of unplanned arthritis-related medical consultations (p=0.03) and a significant increase in ASE for pain (p=0.01) and other symptoms (p=0.02) and self-rated health (p=0.04) among the intervention group but not for the control group. However, there were similarities in outcome measures of pain while switching from a sitting to a standing position, fatigue rating and physical functional limitation (p=0.15; p=0.22 and p=0.91, respectively) for both groups. Our findings add to the evidence that the modified arthritis empowering programme improved perception of control of osteoarthritis and three health outcomes after 12 months of treatment.     

Development of a magnetic-resonance-compatible photoplethysmograph amplifier for behavioral and emotional studies

The purpose of the present study was to develop a magnetic resonance (MR) compatible photoplethysmograph (PPG) system that can measure the raw PPG signal during MR image acquisition. The system consists of an optic sensor that measures the optic signal, an optic cable that transmits a near-infrared optic signal, a signal amplifier, and a filter for noise removal. To minimize interactive noise, only the optic cable and the optic sensor module are located inside the MR room; the signal amplifier and filter are located outside the MR room. An experiment verified that a reliable PPG signal can be obtained without causing a deterioration in the MR image.     

Medical Dramas and Viewer Perception of Health: Testing Cultivation Effects

By using a national representative sample (N = 11,555), the current study tested cultivation theory and aimed at understanding the relationship between medical drama watching and viewer perception and beliefs related to health. Findings suggest that heavy viewers of medical dramas tend to underestimate the gravity of chronic illnesses such as cancer and cardiovascular disease and undermine the importance of tackling these issues. Heavier viewers of medical dramas, compared to lighter viewers, also tend to take a more fatalistic perspective about cancer. Theoretical implications for cultivation theory and practical implications for health policy makers and drama producers are discussed.     

Creative Reappropriation: Barth's Use of Calvin in the Münster Ethics (1928/29)

This article demonstrates Calvin's impact upon Barth's ethics through a close reading of Barth's MÏnster lectures on ethics. Already in these early lectures Barth insisted on the coherence of dogmatic and ethical reflection, and developed the basic structure and some characteristic themes of his mature ethical reflection in the Church Dogmatics . By showing the ways in which Barth was influenced by Calvin in these formative first ethics lectures the case is made that a thorough understanding of Calvin's theology is necessary for a correct appreciation of Barth's ethics and of his theology as a whole.     

Cognitive processing of corporate social responsibility campaign messages: the effects of emotional visuals on memory

ABSTRACT

This study explored the effects of visual strategies on consumers’ memory of corporate social responsibility (CSR) campaign messages. Using the limited capacity model of motivated mediated message processing (LC4MP), we examined how emotional CSR messages are cognitively processed—specifically, how emotional visuals in CSR messages affect two subprocesses of information processing: encoding and storage. We conducted a 2 (valence: positive vs. negative) × 2 (arousal: moderately arousing vs. highly arousing) within-subjects experiment across four different CSR issues. The results showed that recognition accuracy and sensitivity (d′) of company logos were best for moderately arousing negative images, whereas for recognition accuracy and sensitivity (d′) of company names, there were no significant differences across the emotional conditions. For cued recall of companies associated with CSR issues, the pattern was different—highly arousing negative images with aversive cues were the most effective. We discuss the theoretical and practical implications of these findings.     

Parent–Child Conflict Profiles in Chinese American Immigrant Families: Links to Sociocultural Factors and School‐Age Children's Psychological Adjustment

Research suggests that parent–child conflict is a salient family process in Asian immigrant families and often a stressful experience for Asian American youth due to value discrepancies between Asian and Western cultures. The present study examined ratings of parent–child conflict across conflict topics from parents' and children's perspectives in a sample of Chinese American immigrant families with school‐age children (N = 239; age = 7.5–11 years). Latent profile analyses identified three parent‐rated conflict profiles and four child‐rated conflict profiles. Parent and child conflict profiles were unrelated to each other and differentially related to family sociocultural factors and children's psychological adjustment. Parents' moderate conflict profile scored highest on parent‐rated child behavior problems and had the highest household density and lower parent Chinese orientation. Children's moderate‐specific and high conflict profiles scored higher on child‐reported behavior problems than the low conflict profile. These results highlight the need to assess family conflict from both parents' and children's perspectives and target parent–child conflict communication as a pathway to prevent or reduce behavioral problems in Chinese American children of immigrant families.     

A Nondegenerate Penalized Likelihood Estimator for Variance Parameters in Multilevel Models

Group-level variance estimates of zero often arise when fitting multilevel or hierarchical linear models, especially when the number of groups is small. For situations where zero variances are implausible a priori, we propose a maximum penalized likelihood approach to avoid such boundary estimates. This approach is equivalent to estimating variance parameters by their posterior mode, given a weakly informative prior distribution. By choosing the penalty from the log-gamma family with shape parameter greater than 1, we ensure that the estimated variance will be positive. We suggest a default log-gamma(2,λ) penalty with λ→0, which ensures that the maximum penalized likelihood estimate is approximately one standard error from zero when the maximum likelihood estimate is zero, thus remaining consistent with the data while being nondegenerate. We also show that the maximum penalized likelihood estimator with this default penalty is a good approximation to the posterior median obtained under a noninformative prior. Our default method provides better estimates of model parameters and standard errors than the maximum likelihood or the restricted maximum likelihood estimators. The log-gamma family can also be used to convey substantive prior information. In either case—pure penalization or prior information—our recommended procedure gives nondegenerate estimates and in the limit coincides with maximum likelihood as the number of groups increases.
