Multidimensional Comparison of Personality Characteristics of the Big Five Model, Impulsiveness, and Affect in Pathological Gambling and Obsessive–Compulsive Disorder

The phenomenological resemblance between pathological gambling (PG) and obsessive-compulsive disorder (OCD) has led to suggestions that PG be categorized as an obsessive-compulsive-spectrum disorder (OCSD). This study aimed to explore whether PG resembles OCD in terms of personality and temperament. Fifteen patients with PG, 18 patients with OCD, and 33 healthy control subjects were included in the study. The study subjects were all male and drug na?ve. We analyzed data obtained from three self-report questionnaires assessing personality, impulsiveness, and affect: the short version of the NEO Personality Inventory-Revised (NEO-PI-R), the Barratt Impulsiveness Scale-11 (BIS-11), and the Positive Affect and Negative Affect Schedule (PANAS). Participants with PG and OCD demonstrated less conscientiousness (F = 7.089, P = .002) and less openness to experience (F = 6.268, P = .003) and less positive affect (F = 15.816, P < .001) than did healthy controls. The two diagnostic groups did not differ from each other with respect total BIS-11 scores, but those with OCD showed more neuroticism than did those with PG and healthy controls ( F = 9.556, P < .001), and those with PG obtained higher scores on the non-planning impulsiveness factor of BIS-11 than did those with OCD or healthy controls ( F = 9,835, P < .001). PG and OCD share similar profiles in terms of personality and temperament. This study provides phenomenological evidence supporting the conceptualization of PG as an OCSD.     

Maximizing Throughput of Bucket Brigades on Discrete Work Stations

One way to coordinate workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. The throughput of a bucket brigade on discrete work stations may be compromised due to blocking even if workers are sequenced from slowest to fastest. For a given work distribution on the stations we find policies that maximize the throughput of the line. When workers have very different production rates, fully cross‐training the workers and sequencing them from slowest to fastest is almost always the best policy. This policy outperforms other policies for most work distributions except for some cases in which limiting the work zones of workers produces higher throughput. In environments where the work can be adjusted across stations, we identify conditions for a line to prevent blocking.

The Evolution of Korean corporate HRD: launching,growing pains,and transforming

Enthusiasm and greater attention from the international HRD community to Korea has motivated us to conduct research on the evolution of Korean corporate HRD in order to explore where we are now and where we are heading. Research literature on the topic, however, was minimal. The purpose of this study was to examine the evolution of Korean corporate HRD through interviews with 18 HRD researchers and practitioners who have witnessed the field’s growth. In addition, we reviewed the literature and company archives of HRD activities. We identified three major historical milestones of Korean corporate HRD including: the launching period in the 1980s, the growing pains period in the 1990s, and the transforming period from the 2000s to the present. We addressed major trends and issues of Korean corporate HRD in an attempt to generate a future research agenda.     

Structural determinants of team performance: the mutual influences of learning culture,creativity, and knowledge

This study examined the effects of supportive learning culture, team creativity, and collaborative knowledge creating practices on team performance. A survey was used to collect data from a total of 228 knowledge workers from nine Korean organizations. Analyses included measuring item internal consistency, validating proposed constructs, and examining structural relationships using Structural Equation Modelling. The proposed research model was validated in terms of item internal consistency and a model-fit in the Korean business context. Supportive learning culture had a positive and direct influence on team creativity and on the teams' collaborative knowledge creation practices; however, it had an indirect influence on the team performance through the variables of team creativity and knowledge creation practices. In the conclusion, limitations, implications, and further research suggestions are discussed.     

Confidence intervals for nonparametric quantile regression: an emphasis on smoothing splines approach

In this paper we consider the problem of constructing confidence intervals for nonparametric quantile regression with an emphasis on smoothing splines. The mean‐based approaches for smoothing splines of Wahba (1983) and Nychka (1988) may not be efficient for constructing confidence intervals for the underlying function when the observed data are non‐Gaussian distributed, for instance if they are skewed or heavy‐tailed. This paper proposes a method of constructing confidence intervals for the unknown τth quantile function (0<τ<1) based on smoothing splines. In this paper we investigate the extent to which the proposed estimator provides the desired coverage probability. In addition, an improvement based on a local smoothing parameter that provides more uniform pointwise coverage is developed. The results from numerical studies including a simulation study and real data analysis demonstrate the promising empirical properties of the proposed approach.     

Psychological Differences Between HIV-Positive Mothers Who Disclose to All, Some, or None of Their Biological Children

This study explored the psychological differences between HIV-positive women who disclosed their serostatus to all, some, or none of their biological children. Data from this project come from a larger, longitudinal investigation of the disclosure process of HIV-infected women. Data were obtained regarding the disclosure processes and the psychological adjustment of women with children ( n  = 90) based on measures of depression, anxiety, and stress. Results suggest that women who disclose to all, some, or none of their children are not significantly different with regard to emotional well-being. Implications for marriage and family therapists are provided.     

Spill‐Up and Spill‐Over of Trust: An Extended Test of Cultural and Institutional Theories of Trust in South Korea1

In comparison to the heated debate over the origins of trust in political institutions, few studies have empirically examined the linkage between trust in political and nonpolitical institutions at the individual level. In this study, we utilize a two‐step methodology to investigate attitudes toward the government in the broader context of attitudes toward related nonpolitical institutions in South Korea. Results from latent class analysis reveal that political trust is an integrated part of a more general set of attitudes toward social and economic institutions. In addition, results from multinomial logistic regression analysis corroborate past studies that found a positive relationship between perceptions of institutional performance and trust in institutions while partially supporting theories advocating the importance of interpersonal trust for institutional trust. This study points to the possibility of interpersonal trust “spilling up” to trust in institutions and the likelihood that trust in one institution “spills over” to trust in other related institutions.     

LABOR'S SHARE,THE FIRM'S MARKET POWER,AND TOTAL FACTOR PRODUCTIVITY

We investigate the relationship between labor's share, firm's market power, and the elasticity of output with respect to labor input using an approach based on an unobserved components model. The approach yields time‐varying estimates of market power and the elasticity. Evidence on the market power of firms (which we find to be rising since 2000) gives a deeper understanding of movements in labor's share and the labor wedge. The generated values of the elasticity yield revised estimates of total factor productivity growth which is informative about the extent of the downward bias inherent in traditional estimates which use labor's share as a proxy for the elasticity.
