Curvilinear relationships between role stress and innovative performance: Moderating effects of perceived support for innovation

Curvilinear relationships between role stress and innovative performance were explored in a study conducted in Taiwan and mainland China. Results showed that when perceived support for innovation was low, role conflict showed a U‐shaped relationship with both self‐rated and supervisor‐rated innovative performance, which contrasts sharply with the well known inverted U‐shaped relationship between challenge stress and performance. Role ambiguity showed a similar but weaker pattern with regard to supervisor‐rated innovative performance. When perceived support for innovation was high, role conflict showed a generally positive relationship with both self‐rated and supervisor‐rated innovative performance, but role ambiguity showed no significant relationship with supervisor‐rated innovative performance. Theoretical and applied implications of these findings are discussed.     

Gender‐specific factors associated with the suicidal ideation of children in Taiwan: A large‐scale cross‐sectional study

We examined the relationship between suicidal ideation (SI) and the depressed mood, life stress and parenting styles in children. A large‐scale survey was conducted including 5328 children from 65 elementary schools in Taiwan. SI was measured by asking children if any suicidal thoughts had occurred in the previous month. A series of regression models was analysed separately for male and female students. Compared with boys, girls demonstrated a higher proportion of SI. Among boys, SI was significantly associated with a high level of perceived environmental stress (adjusted odds ratio [aOR] = 2.61), a high degree of depressed mood (aOR = 2.39), authoritative (aOR = 1.72) and authoritarian (aOR = 2.53) parenting styles and two or more life‐stress events (aOR = 1.45). A high level of perceived environmental stress (aOR = 2.09), a high degree of depressed mood (aOR = 2.89) and an authoritarian parenting style (aOR = 1.76) were significantly associated with the SI in girls. Gender‐specific interventions aimed at preventing SI must enhance support systems at school and at home, particularly for students who suffer from a high degree of stress and depressed mood, and are subjected to an authoritarian parenting style.     

The relationships between television viewing in midlife and the development of Alzheimer's disease in a case-control study

The relationship between leisure activities and development of cognitive impairment in aging has been the subject of recent research. We examined television viewing in association with risk of developing Alzheimer's disease (AD) in a case-control study. Given recent focus on the importance of intellectually stimulating activities as preventive measures against cognitive decline, it is important to examine the effects of less stimulating but common activities. Data are from 135 Alzheimer's disease cases and 331 healthy controls. Demographic characteristics and life history questionnaire responses on the number of hours spent on 26 leisure activities during middle-adulthood (ages 40-59) were analyzed. Logistic regression was used to examine the effects of middle-adulthood leisure activities on case vs. control status. Results indicate that for each additional daily hour of middle-adulthood television viewing the associated risk of AD development, controlling for year of birth, gender, income, and education, increased 1.3 times. Participation in intellectually stimulating activities and social activities reduced the associated risk of developing AD. Findings are consistent with the view that participation in non-intellectually stimulating activities is associated with increased risk of developing AD, and suggest television viewing may be a marker of reduced participation in intellectually stimulating activities.     

Emotional intelligence, teamwork effectiveness, and job performance: the moderating role of job context

We advance understanding of the role of ability-based emotional intelligence (EI) and its subdimensions in the workplace by examining the mechanisms and context-based boundary conditions of the EI-performance relationship. Using a trait activation framework, we theorize that employees with higher overall EI and emotional perception ability exhibit higher teamwork effectiveness (and subsequent job performance) when working in job contexts characterized by high managerial work demands because such contexts contain salient emotion-based cues that activate employees' emotional capabilities. A sample of 212 professionals from various organizations and industries indicated support for the salutary effect of EI, above and beyond the influence of personality, cognitive ability, emotional labor job demands, job complexity, and demographic control variables. Theoretical and practical implications of the potential value of EI for workplace outcomes under contexts involving managerial complexity are discussed.     

With or without a hole: young infants' sensitivity for topological versus geometric property

Evidence from adult psychophysics, brain imaging, and honeybee's behaviour has been reported to support the notion that topological properties are the primitives of visual representation (Chen, 1982 Science 218 699-700). Here, we ask how the sensitivity to topological property might originate during development. Specifically, we tested 1.5- to 6-month-old infants' visual sensitivity for topological versus geometric properties with the forced-choice novelty preference technique. A disk and a ring were used in the topologically different condition (experiment 1), while a disk and a triangle were used in the geometrically different condition (experiment 2). Spontaneous preferences for the disk, the ring, and the triangle were measured pairwise using the preferential looking-time technique (experiment 3). The results showed that infants could reliably discriminate stimuli based on topological differences, but failed to do so with geometric differences. Moreover, in the generalisation task, infants showed higher novelty preference for the topologically different figure (the ring). In addition, the results of both experiments cannot be attributed to a spontaneous preference for the ring or for the disk. Further analysis on individual infants' age and performance revealed two distinct developmental trends. Infants seem to be sensitive to topological differences as young as 1.5 months, while their ability to discriminate geometric differences was at chance before 3 months and gradually improved with age. Taken together, our findings suggested an early sensitivity for topological property, at least for the detection of stimuli with or without a hole.     

Scalar implicature and contrastive explanation

I argue for a subsumption of any version of Grice’s first quantity maxim posited to underlie scalar implicature, by developing the idea of implicature recovery as a kind of explanatory inference, as e.g. in science. I take the applicable model to be contrastive explanation, while following van Fraassen’s analysis of explanation as an answer to a why-question. A scalar implicature is embedded in such an answer, one that meets two probabilistic constraints: the probability of the answer, and ‘favoring’. I argue that besides having application at large, outside of linguistic interpretation, these constraints largely account not only for implicatures based on strength order, logical and otherwise, but also for unordered cases. I thus suggest that Grice’s maxim and its descendants are expressions of general explanatory constraints, as they happen to be manifested in this particular explanatory task. I conclude by briefly discussing how I accordingly view Grice’s system outside of scalar implicature.     

Evaluation of a Peer-Led Mutual Support Group for Chinese Families of People with Schizophrenia

Family interventions in schizophrenia have shown positive effects on patients but little attention has been paid to their effects on family members, particularly those in non-Western countries. This randomized controlled trial evaluated the effectiveness of a bi-weekly, 12-session, family-led mutual support group for Chinese caregivers of schizophrenia sufferers over 6 months compared with standard psychiatric care. It was conducted with 76 families of outpatients with schizophrenia in Hong Kong of whom 38 were assigned randomly to either a mutual support group or standard care. Families' psychosocial health status and patients' symptom severity and length of re-hospitalizations at recruitment, one-week and 12-month post-intervention were compared between groups. Results of repeated-measures mixed model indicated that the mutual support group experienced significantly greater improvements in families' burden, functioning and number of support persons and length of patients' re-hospitalizations at two post-tests. The findings provide evidence that mutual support groups can be an effective family-initiated, community-based intervention for Chinese schizophrenia sufferers.     

The Mediating Processes Linking Applicant Personality Traits and Interviewer Evaluation

This study examines interview preparations (i.e., social preparation and background preparation) and impression management (IM) tactics (i.e., self‐focused IM and other‐focused IM) as the mechanisms between applicant personality characteristics and interviewer evaluation. Data were collected from both actual job applicants and interviewers. Results show that personality characteristics (i.e., extraversion and conscientiousness) have indirect effects on interviewer evaluation in terms of perceived person–job fit (P–J fit) and interpersonal liking through these two types of applicant behaviors. This study accomplishes two goals: (1) it extends the socioanalytic theory of personality ( Hogan, 1996 ) by testing the intervening roles played by applicants' behaviors that correspond to getting along with and getting ahead of others; and (2) it suggests that these applicant behaviors might be important cues for practical interviewers' effective assessment of applicants' performance‐related characteristics.     

Test of a Model Linking Applicant Résumé Information and Hiring Recommendations

Previous research has shown that résumé information (i.e., including both content and aesthetics) influences recruiters' hiring recommendations. This study extends previous research by proposing and testing a model that examines mediating processes underlying the relationship between résumé information and hiring recommendations in real employment interviews for actual job openings. Results from 62 interviewers of 30 firms partially supported our hypotheses and showed that the three types of recruiters' inferences (i.e., including professional knowledge, interpersonal skills, and general mental ability) from applicants' résumé information mediated the effects of résumé information on hiring recommendations.     

Evaluating a metacognitive and planned happenstance career training course for taiwanese college students

This study used a pretest—posttest, nonequivalent control group, quasi experimental design to examine the effectiveness of a 12‐week, metacognitive and planned happenstance career training course for Taiwanese college students. The treatment groups significantly increased their career competencies in metacognitive, cognitive, affective, and behavioral dimensions over the comparison and nonequivalent control groups.
