Pathological gambling is characterized by excessive gambling behavior which influences the life and well-being of a person in a dysfunctional way. It often leads to severe consequences in social and family life, career and material matters. This can also include illegal acts. In the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) excessive gambling was classified under impulse-control disorders but was renamed as gambling disorder (GD) and reclassified under the category “substance-related and addictive disorders” in DSM-5, due to parallels to substance use disorders in the clinical characteristics as well as genetic and neurobiological factors. In Germany, approximately 0.5?% of the adult population suffer from GD. Especially gambling machines are associated with an increased risk of gambling-related problems. Common comorbidities are substance-related and affective disorders. The most important risk factors are young age, male gender, a history of migration, gambling-related problems in the family, unemployment, a low educational level and low household income. Delinquent behavior was not considered to be a sufficiently discriminative factor for GD, although there is a correlation between delinquency and gambling behavior. In addition, those GD subjects who show delinquent behavior also show a specific risk profile. Thus, mental health professionals should be aware of possible psychosocial consequences in GD, such as illegal acts, and this should be addressed in the effective treatment strategies, such as cognitive behavioral therapy. Moreover, it is necessary to improve the access routes for affected people into healthcare system in order to ensure early detection and treatment of the disease. 相似文献

Analysing ordinal data is becoming increasingly important in psychology, especially in the context of item response theory. The generalized partial credit model (GPCM) is probably the most widely used ordinal model and has found application in many large-scale educational assessment studies such as PISA. In the present paper, optimal test designs are investigated for estimating persons’ abilities with the GPCM for calibrated tests when item parameters are known from previous studies. We find that local optimality may be achieved by assigning non-zero probability only to the first and last categories independently of a person's ability. That is, when using such a design, the GPCM reduces to the dichotomous two-parameter logistic (2PL) model. Since locally optimal designs require the true ability to be known, we consider alternative Bayesian design criteria using weight distributions over the ability parameter space. For symmetric weight distributions, we derive necessary conditions for the optimal one-point design of two response categories to be Bayes optimal. Furthermore, we discuss examples of common symmetric weight distributions and investigate under what circumstances the necessary conditions are also sufficient. Since the 2PL model is a special case of the GPCM, all of these results hold for the 2PL model as well. 相似文献

The Federal and State offices of criminal investigation have offered support to the police authorities for more than 10 years in the investigation of homicide and sexual assault cases as well as other relevant cases of particular significance by behavioral analysis. The German police has systematically developed the FBI approach of profiling and established quality standards. On the basis of a case study the process of case analysis is described from the evaluation of case data, the reconstruction and the process of reviewing up to providing a profile of the offender. 相似文献

Recent meta‐analyses (e.g. Barrick, Mount, & Judge, 2001 ) found openness to experience, a factor in the five‐factor model of personality, to be uncorrelated with job performance. We argue that, among others, insignificant validity is due to the broad and heterogeneous nature of the construct. In line with our hypotheses, we found internal structure of openness to be multidimensional. Further analyses on subdimensional and facet level revealed large differences in criterion‐ and construct‐related validity. It could be demonstrated that a subdimension labeled epistemic curiosity and, especially, the facet openness to ideas, which includes aspects like curiosity, flexibility, willingness to learn, and creativity, are highly relevant for work‐related criteria and so far understudied in organizational research. 相似文献

As an extension of Lastovicka's four-mode components analysis ann-mode components analysis is developed. Using a convenient notation, both a canonical and a least squares solution are derived. The relation between both solutions and their computational aspects are discussed.The first draft was written while Wansbeek was with the Netherlands Central Bureau of Statistics. We thank Jaap Verhees for performing the computations and for many discussions on the subject, John Lastovicka for kindly making available his data to us, and the Editor, the referees, Jeroen Weesie and Pieter Kroonenberg for their useful comments. 相似文献

The effects of dynamic testing procedures on Raven Coloured Matrices performance, visual scanning procedures, test anxiety, and orientation to the test situation were assessed. The subjects were 72 third-grade children. The results supported the hypotheses of the study showing that (1) dynamic assessment procedures involving either verbalization or elaborated feedback lead to higher levels of Raven Matrices performance; that (2) dynamic assessment modifies visual search behaviors; and that (3) dynamic assessment reduces test anxiety and negative orientation to the testing situation. The results are interpreted as offering construct validation to the assessment approaches used. 相似文献

Value-based decision making (VBDM) is a principle that states that humans and other species adapt their behavior according to the dynamic subjective values of the chosen or unchosen options. The neural bases of this process have been extensively investigated using task-based fMRI and lesion studies. However, the growing field of resting-state functional connectivity (RSFC) may shed light on the organization and function of brain connections across different decision-making domains. With this aim, we used independent component analysis to study the brain network dynamics in a large cohort of young males (N = 145) and the relationship of these dynamics with VBDM. Participants completed a battery of behavioral tests that evaluated delay aversion, risk seeking for losses, risk aversion for gains, and loss aversion, followed by an RSFC scan session. We identified a set of large-scale brain networks and conducted our analysis only on the default mode network (DMN) and networks comprising cognitive control, appetitive-driven, and reward-processing regions. Higher risk seeking for losses was associated with increased connectivity between medial temporal regions, frontal regions, and the DMN. Higher risk seeking for losses was also associated with increased coupling between the left frontoparietal network and occipital cortices. These associations illustrate the participation of brain regions involved in prospective thinking, affective decision making, and visual processing in participants who are greater risk-seekers, and they demonstrate the sensitivity of RSFC to detect brain connectivity differences associated with distinct VBDM parameters. 相似文献

The concept of the artes liberales originates in antiquity and was, especially in the Anglo-Saxon area and during the 17th and 18th centuries, remodelled into a socially, educationally, and politically modern educational concept. In this process, the progress within the empirical sciences and the formation of an early civil public are of the utmost importance. In the course of these transformations, the absolute force of church and state is called into question; educational concepts which have to be called modern emerge from it. 相似文献
