Purpose Cyber deviance of adolescents has become a serious social problem. With a widespread use of smartphones, incidents of cyber deviance have increased in Korea and both quantitative and qualitative damages such as suicide and depression are increasing. Research has been conducted to understand diverse factors that explain adolescents' delinquency in cyber space. However, most previous studies have focused on a single theory or perspective. Therefore, this study aims to comprehensively analyze motivations of juvenile cyber deviance and to develop a predictive model for delinquent adolescents by integrating four different theories on cyber deviance. Design/methodology/approach By using data from Korean Children & Youth Panel Survey 2010, this study extracts 27 potential factors for cyber deivance based on four background theories including general strain, social learning, social bonding, and routine activity theories. Then this study employs econometric analysis to empirically assess the impact of potential factors and utilizes a machine learning approach to predict the likelihood of cyber deviance by adolescents. Findings This study found that general strain factors as well as social learning factors have positive effects on cyber deviance. Routine activity-related factors such as real-life delinquent behaviors and online activities also positively influence the likelihood of cyber diviance. On the other hand, social bonding factors such as community commitment and attachment to community lessen the likelihood of cyber deviance while social factors related to school activities are found to have positive impacts on cyber deviance. This study also found a predictive model using a deep learning algorithm indicates the highest prediction performance. This study contributes to the prevention of cyber deviance of teenagers in practice by understanding motivations for adolescents' delinquency and predicting potential cyber deviants.

This study aims to investigate a model for reducing workplace deviance from employees' perspectives. Specifically, it examines the relationship between workplace spirituality and workplace deviance through the improvement of organizational commitment. Through the quantitative approach, questionnaires were distributed to 400 civil servants in the various government agencies in Indonesia. Structural Equation Model with Analysis of Moment Structures (SEM-AMOS) was used to analyze the data and test the hypotheses. The results reveal that workplace spirituality has no significant negative effect directly on workplace deviance, but it has a significantly positive effect on organizational commitment. Organizational commitment also has a significant negative effect on workplace deviance. The non-significance of workplace spirituality's direct effect on workplace deviance proves that there is a full mediation effect of organizational commitment. It implies that, to reduce workplace deviance, merely workplace spirituality is not adequate, but it should enhance organizational commitment. The findings can add an understanding of the empirical evidence related to the relationship between workplace spirituality, organizational commitment, and workplace deviance. Practically, the top decision-makers in civil servant institutions need to consider the right strategies, policies, and real efforts to carry out workplace spirituality practices and organizational commitment by designing a control system.

The purpose of this study was to examine the influence of person-job fit on organizational deviance and mediating effects of job satisfaction and organizational commitment(affective commitment and continuance commitment) on this relationship. Data were collected from 533 employees who were working in social welfare organizations by questionnaires. The result indicated that there were significantly positive relationships between person-job fit and job satisfaction or organizational commitment(affective commitment and continuance commitment). Also, there were significantly positive relationships between job satisfaction and affective commitment or continuance commitment. In addition, job satisfaction and affective commitment were negatively related to organizational deviance, and job satisfaction is more strongly related to organizational deviance than affective commitment. It was found that job satisfaction partially mediated the relationship between person-job fit and organizational commitment(affective commitment and continuance commitment) and affective commitment partially mediated the relationship between job satisfaction and organizational deviance. It was found that the person-job fit indirectly impacts organizational deviance though job satisfaction and affective commitment. Based on these results, the implication of this study and future research tasks were discussed.

Purpose - While studying the topic of seeking behavioral excellence (proactive and creative competence) in organization, scholars have presented a variety of literature sprinkled with countless theories on behavioral competence. Research design, data, and methodology - Foremost among the several theories on this topic are two distinct sets of behavioral theories: OCB (Organizational Citizenship Behavior) and Constructive Deviance. Both of these theories attempt to posit their usefulness in positive organizational outcomes (such as organizational effectiveness, quality, performance, and innovations). Results - However, their proposed constructs are opposing and studies are conducted in isolation, thereby creating a significant literature gap and omitting the possibility of being inclusive of the best that both OCB and constructive deviance have to offer. Conclusions - The article bridges the gap by critically examining OCB and constructive deviance and including a consideration of other empirical studies in an attempt to be comprehensive while, at the same time, seeking to find an effective behavioral construct that is both appropriate and conducive for positive organizational outcomes in the context of the current business environment.

This study set out to investigate internet experience effect on youth's delinquency. Specifically, internet experience means internet deviant behaviors and the frequency of the internet use including chatrooms, computer game, and pornography. Data came from Korea Youth Panel Survey 2007. Analysis methods hierarchical regression analysis. The major findings of this study are as follows. First, results showed that adolescents use computer every day about 2 hour 40 minutes for using internet such as chatrooms, computer game, and pornography. And 29.4% of adolescents reported internet deviance. Second, the internet use and the internet deviance influenced positively juvenile delinquency. Third, the relationship between internet use and juvenile delinquency was mediated by aggression and internet deviance. These results means that youth spend much time online every day for using internet, and engaged internet deviance. This online experience influence juvenile delinquency offline world. And limitations and implications of this study were discussed with respect to further studies.

The quasi-likelihood models which greatly widened the scope of generalized linear models are widely used in data analysis where a likelihood is not available. Since a quasi-likelihood may not appear to be an ordinary likelihood for any known distribution in the natural exponential family, to fit the quasi-likelihood models the standard statistical packages such as GLIM, GENSTAT, S-PLUS and so on may not directly applied. SAS/IML is very useful for fitting of such models. In this paper, we present simple SAS/IML(version 6.11) program which helps to fit and analyze the quasi-likelihood models applied to the leaf-blotch data introduced by Wedderburn(1974), and the problem with deviance useful generally to model checking is pointed out, and then its solution method is mention through the data analysis based on this quasi-likelihood models checking.

In this paper, the use of Bayes factors and the deviance information criterion for model selection are compared in a Bayesian accelerated life testing setup. In Bayesian accelerated life testing, the most used tool for model comparison is the deviance information criterion. An alternative and more formal approach is to use Bayes factors to compare models. However, Bayesian accelerated life testing models with more than one stressor often have mathematically intractable posterior distributions and Markov chain Monte Carlo methods are employed to obtain posterior samples to base inference on. The computation of the marginal likelihood is challenging when working with such complex models. In this paper, methods for approximating the marginal likelihood and the application thereof in the accelerated life testing paradigm are explored for dual-stress models. A simulation study is also included, where Bayes factors using the different approximation methods and the deviance information are compared.

The purpose of this present study was to investigate the influence of abusive supervision on strain-based work interference with family and interpersonal deviance. In addition, this study examined the mediating effect of subordinates' emotional labor toward supervisors and the moderating effect of hierarchical organizational climates on emotional labor, perceived organizational family support on strain-based work-family conflict, and social network on interpersonal deviance. The results are summarized as follows: (1) abusive supervision was positively related to subordinates' emotional labor toward supervisors. (2) Emotional labor was positively related to strain-based work-family conflict and interpersonal deviance. (3) Subordinates' emotional labor mediated the relationship between abusive supervision and the two outcome variables. (4) Hierarchical organizational climates moderated the relationship between abusive supervision and emotional labor. (5) Perceived organizational family did not have moderating effect between emotional labor and strain-based work-family conflict. (6) Social network had moderating effect but it did not influence interpersonal deviance as predicted by the hypothesis. Based on the results, implications of findings, limitations, and suggestions for future research were discussed.

In this paper we study the Hellinger distance based goodness-of-fit tests that are analogs of likelihood ratio tests. The minimum Hellinger distance estimator (MHDE) in normal models provides an excellent robust alternative to the usual maximum likelihood estimator. Our simulation results show that the Hellinger deviance test (Simpson 1989) based goodness-of-fit test is robust when data contain outliers. The proposed hellinger deviance test(Simpson 1989) is a more direcct method for obtaining robust inferences than an automated outlier screen method used before the likelihood ratio test data analysis.

This study investigated the mediating role that subordinates' job satisfaction might play in influencing the relationships between abusive supervision and subordinates' organizational identification and workplace deviance behavior(WDB-O). With data gathered from employees(N=281) representing a wide array of organizations, structural equation modeling was used to test hypotheses. The results showed that abusive supervision is negatively related to job satisfaction and consequently organizational identification, positively associated with organizational deviance behavior through job satisfaction indirectly and has a direct effect on WDB-O.
