Suicide mortality of suicide attempt patients discharged from emergency room, nonsuicidal psychiatric patients discharged from emergency room, admitted suicide attempt patients, and admitted nonsuicidal psychiatric patients

The suicide mortality rate and risk factors for suicide completion of patients who presented to an emergency room (ER) for suicide attempt and were discharged without psychiatric admission, patients who presented to an ER for psychiatric problems other than suicide attempt and were discharged without psychiatric admission, psychiatric inpatients admitted for suicide attempt, and psychiatric inpatients admitted for other reasons were examined. The records of 3,897 patients who were treated at a general hospital in Seoul, Korea, from July 2003 to December 2006 were reviewed. Forty-three of the 3,897 subjects died by suicide during the 2.5-year observation period. Compared to the general Korean population, the suicide mortality rate was 82-fold higher for suicide attempt patients, admitted; 54-fold higher for suicide attempt patients, discharged; 21-fold higher for nonsuicidal patients, admitted; and 11-fold higher for nonsuicidal patients, discharged. In all four groups, diagnosis of a depressive disorder and suicide attempt at presentation were each significant independent risk factors for suicide completion. These results highlight the need for suicide prevention strategies for depressed patients who present to the ER or are admitted to a psychiatric ward after a suicide attempt.     

Dysfunctional Behavior among Sales Representatives: The Effect of Supervisory Trust,Participation, and Information Controls

This study investigates the efficacy of supervisory trust, participation, and information controls in curbing dysfunctional salesperson behavior so that salesperson actions are in line with organizational goals. Using a sample of 210 salespeople, we develop and test a model incorporating supervisory trust, participation, information controls (output information, activity information, and capability information), and dysfunctional behavior. Output and activity information controls directly affect dysfunctional behavior, whereas capability information controls work positively through trust in the supervisor to reduce dysfunctional behavior. Providing sales representatives with information about their capabilities appears to enhance the supervisor–salesperson trust relationship. Results also indicate that salespeople’s supervisory participation is an effective lever for reducing dysfunctional salesperson behavior through the intervening role of trust in the supervisor.     

Effect of a nanoporous surface on photoluminescence from nanopatterned GaN thin films fabricated by anodic alumina templates

GaN photonic crystal slabs on InGaN/GaN multi-quantum well light-emitting diodes have been formed by dry etching using nanoporous anodic alumina templates, which have a periodic lattice constant of 105 nm and a hole diameter of 45 nm. The photonic crystal slab shows an enhanced intensity of photoluminescence due to the nanohole pattern array producing Fabry–Perot like interference. A rough surface of nanoholes results in a broad spectrum with a small oscillation, and well-ordered multiple facets of nanoholes results in a relatively sharp spectrum with a large oscillation.     

The effects of behavioral inhibition/approach system as predictors of Internet addiction in adolescents

This study aimed to determine how the Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) affect Internet addiction in adolescents. Two hundred and eleven high school students participated in this study and completed the Young’s Internet Addiction Test (IAT), BIS/BAS scales, and several self-administered questionnaires about depression, anxiety, and impulsivity. Hierarchical regressions showed that BIS and BAS × BIS emerged as significant predictors of IAT; however, only BAS-fun seeking subscale predicted IAT among BAS related subscales. In further analyses, the BAS-fun seeking subscale was mediated by impulsivity and anxiety, and BIS was mediated by anxiety and depression. The current findings imply that BIS and BAS interdependently influence vulnerability to Internet addiction through both shared (anxiety) and different (depression and impulsivity, respectively) pathways.     

Factors of regular sponsorship of African children: A cross-ethnic study

This study examined psychological well-being influences of personal factors on regular sponsorship of, or donation to, African children living in Africa. Study participants (N = 597) were 338 Koreans (50.3% female, n = 170) and 259 Chinese (56.8% female, n = 147). They responded to measures of psychological well-being, individual social responsibility, social impression management, and subjective norms. Following multiple group analyses applying structural equation modelling, subjective well-being influenced psychological well-being among the Korean donors; whereas social responsibility influenced psychological well-being among the Chinese donors. In both the Korean and Chinese groups, psychological well-being was associated with an increased regular sponsorship of African children. Latent ethno-cultural personal orientations appear to explain psychological well-being with donation activity.     

The Emergence of Student Creativity in Classroom Settings: A Case Study of Elementary Schools in Korea

This research explores the emergence of student creativity in classroom settings, specifically within two content areas: science and social studies. Fourteen classrooms in three elementary schools in Korea were observed, and the teachers and students were interviewed. The three types of student creativity emerging in the teaching and learning process found in this research were: (a) heuristic creativity when the students express their thoughts about a new concept based on their experience, (b) interpretive creativity when the students explain the meaning of materials based on students' knowledge, and (c) integrative creativity when students generate new solutions or make new products based on their internalized knowledge. The study results will challenge teachers to find instances of student creativity in their teaching and learning situations and to facilitate student creativity when the students interpret data or materials related to the contents of the curriculum.     

An individual's work values in career development

This study examined the mediation effect of career decision self‐efficacy in relation to work values and career decision status. The authors surveyed 308 college students about their own intrinsic (e.g., helping others) and extrinsic (e.g., high income) work values and those of significant others, career decision self‐efficacy, and career decision status. The results indicated that the intrinsic and extrinsic work values of significant others were related to the intrinsic and extrinsic work values of the self and that intrinsic work values were more adaptive than extrinsic work values in career development.     

the role of career stress in the relationship between maladaptive perfectionism and career attitude maturity in south korean undergraduates

Given the central role of career stress in college students' lives, this research examined whether career stress mediated the relationship between maladaptive perfectionism and career attitude maturity in a sample of 185 undergraduate students in South Korea. The results indicated that career ambiguity stress, as measured by a career stress inventory, fully mediated the relationship between maladaptive perfectionism and career attitude maturity. That is, maladaptive perfectionism correlated with greater levels of career ambiguity stress, and greater career ambiguity stress correlated with an unconstructive level of career attitude maturity. The authors discuss the findings' implications for career counselors in college settings.     

Role ambiguity as a moderator of occupational self-efficacy and job satisfaction

Role ambiguity was examined as a moderator of occupational self-efficacy and job satisfaction on the basis of the data obtained from 280 employees of U.S. housing finance agencies in four states. The interaction effect was found to be small but significant. The practical implications of role ambiguity at different levels of occupational self-efficacy were discussed. The value of reducing role ambiguity is higher for those who have low self-efficacy. The theoretical implications of the findings support the inclusion of dispositional and situational interactions in research regarding job satisfaction.
