Problematic Gambling

Tilt in poker is a phenomenon characterized by a loss of control. Tilt could be a risk factor for the development of problematic gambling in poker. To monitor the frequency of tilt episodes during online poker sessions, the Online Poker Tilt Scale (OPTS) was created within the French population. The aim of this study was to develop a short version of this scale, one that was faster to complete, and therefore more appropriate for the online poker player population, which was characterized by an impulsive personality and low survey participation rate. The short version is composed of nine items split into two factors (cognitive regulation and emotional regulation). The OPTS-9 version displayed good psychometric qualities and its scores were strongly correlated with those of the original version. Moreover, this shorter version allows rebalancing of the scale’s factorial structure, which facilitates interpretation of the results. This revised scale will measure the relative frequency of tilt episodes and allow to appropriately study the links between problem gambling and tilt episodes. This shortened 9-item version could be included in future experimental studies, as well as in prevention and treatment programs.RésuméL’inclinaison (tilt) au jeu de poker est un phénomène caractérisé par une perte de contrôle. Elle pourrait être un facteur de risque pour le développement d’un jeu pathologique au poker. Pour suivre la fréquence des épisodes d’inclinaison pendant les séances de poker en ligne, l’échelle Online Poker Tilt Scale (OPTS) a été créée au sein de la population française. Le but de cette étude était de développer une version courte de cette échelle, plus rapide à remplir, donc plus appropriée pour la population de joueurs de poker en ligne qui se caractérise par une personnalité impulsive et un faible taux de participation à des sondages. La version courte est composée de neuf éléments répartis en deux facteurs (régulation cognitive et régulation émotionnelle). La version OPTS-9 présente de bonnes qualités psychométriques et ses pointages sont fortement corrélés avec les pointages de la version originale. De plus, cette version courte permet de rééquilibrer la structure factorielle de l’échelle, ce qui facilite l’interprétation des résultats. Cette échelle révisée mesurera la fréquence relative des épisodes d’inclinaison et permettra d’étudier de façon adéquate les liens entre le jeu pathologique et les épisodes d’inclinaison. Cette version raccourcie à neuf éléments pourrait être incluse dans les futures études expérimentales, ainsi que dans les programmes de prévention et de traitement.

ABSTRACTZarit Burden Interview (ZBI) is the most widely used instrument for assessing the burden experienced by the caregivers of persons with dementia. As part of the Canadian Study of Health and Aging, the 22-item ZBI was administered to a representative sample of 312 informal caregivers of community-dwelling subjects with dementia. The mean score was 22.4 out of 88 (sd: 16.2) and the median score was 18.5, which is far lower than those reported in previous studies using this instrument with convenience samples. There was no significant difference in the burden score according to the age, gender, living arrangement, marital status or employment status of the caregiver. The ZBI score was more strongly correlated to the depressive mood of the caregivers (r = 0.59) and the behaviour problems of the care recipients (r = 0.64) than their cognitive (r = 0.32) and functional (r = 0.31) status. Following a factor analysis, a 12-item short version of the instrument is proposed with two factors: personal strain (3 items) and role strain (9 items).

Assessment Questionnaire

Online poker is a form of gambling where an element of skill may influence the outcome of the game. ‘Tilt’ in poker describes an episode during which the player can no longer control their game by rational decisions. It leads to a loss of control over the game, a loss of emotional regulation, higher cognitive distortion, and a loss of money. This phenomenon, experienced by most players, could be the gateway to excessive gambling. The aim of this study was to assess the links between the frequency of tilt episodes, cognitive distortion, anxiety, depression, sensation seeking and excessive online poker gambling. Our sample is composed of 291 online poker players, with a mean age of 33.8 years (SD = 10.6). Participants completed an online self-assessment questionnaire, measuring the frequency of tilt episodes, cognitive distortion, anxiety, depression and impulsivity. The findings indicated that the frequency of tilt episodes and cognitive distortion were the only significant predictors of excessive online gambling (respectively, r = 0.49 and r = 0.20). Tilt frequency and cognitive distortion were strongly correlated (GRCS, r = 0.60), moderate to low correlations were found for tilt and anxiety (HADS, r = 0.40), and positive and negative urgency (UPPS, r = 0.27). To date, tilt has seldom been studied, and could improve our understanding of online poker gamblers. It could be a new means of identifying at risk gamblers, and thus facilitating preventive measures specifically adapted to this population.

Abstract This paper presents the Teacher Self-efficacy Scale, short version, and the School Collective Beliefs Scale adaptation and search of validities evidences process. After the semantic-cultural adaptation process, this study was composed by 380 educators from the public educational system in the state of São Paulo. The teacher self-efficacy scale, composed by 12 items, was organized into three factors. The School Collective Efficacy scale, composed by 12 items, was structured into two factors. Such adaptations, through the exploratory factor analysis yielded similar factor structure to the original scales, showed good evidence for variance explained, and internal consistency. Convergent validity was verified by the significant correlation between self-efficacy and collective efficacy. Criteria validity was verified through significant correlations between these beliefs and school performance. It is suggested to increase the sample size to confirm these results.

Background: The short version of the Anterior Cruciate Ligament–Return to Sport After Injury (ACL-RSI) scale is a self-reported questionnaire developed to assess the psychological readiness of patients to return to sports after ACL reconstruction (ACLR). Purpose: To translate, cross-culturally adapt, and validate the short version of the ACL-RSI scale into the Arabic language (ACL-RSI-Ar). Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: The original short version of the ACL-RSI scale was forward and backward translated, cross-culturally adapted, and validated following international standardized guidelines. Sixty patients who participated in sports activities and underwent ACLR completed the ACL-RSI-Ar, the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, and Knee injury and Osteoarthritis Outcome Score (KOOS) scales. To assess test-retest reliability, 34 participants completed the ACL-RSI-Ar scale twice. Statistical tests were conducted to test the internal consistency, reliability, and construct and discriminant validity of the ACL-RSI-Ar scale. Results: The ACL-RSI-Ar showed adequate internal consistency (Cronbach alpha = 0.734) and excellent test-retest reliability (intraclass correlation coefficient, 0.871). The ACL-RSI-Ar was strongly correlated with the IKDC (Spearman ρ = 0.515, P < .001) and weakly to strongly correlated with all KOOS subscales (Spearman ρ = 0.247-0.590, P < .05). Patients who returned to sports had significantly higher scores on the ACL-RSI-Ar scale when compared with those who did not return to sports ( P = .001). Conclusion: The short ACL-RSI-Ar scale, as translated, was internally consistent, reliable, and valid for evaluating psychological readiness to return to sports after ACLR in Arabic-speaking patients.

Health Need

To speed up the implementation of the two-dimensional materials in the development of potential biomedical applications, the toxicological aspects toward human health need to be addressed. Due to time-consuming and expensive analysis, only part of the continuously expanding family of 2D materials can be tested in vitro. The machine learning methods can be used—by extracting new insights from available biological data sets, and provide further guidance for experimental studies. This study identifies the most relevant highly surface-specific features that might be responsible for cytotoxic behavior of 2D materials, especially MXenes. In particular, two factors, namely, the presence of transition metal oxides and lithium atoms on the surface, are identified as cytotoxicity-generating features. The developed machine learning model succeeds in predicting toxicity for other 2D MXenes, previously not tested in vitro, and hence, is able to complement the existing knowledge coming from in vitro studies. Thus, we claim that it might be one of the solutions for reducing the number of toxicological studies needed, and allows for minimizing failures in future biological applications.

Pilling is caused by friction pulling and fuzzing the fibers of a material. Pilling is normally evaluated by visually counting the pills on a flat fabric surface. Here, we propose an objective method of pilling assessment, based on the textural characteristics of the fabric shown in optical coherence tomography (OCT) images. The pilling layer is first identified above the fabric surface. The percentage of protruding fiber pixels and Haralick’s textural features are then used as pilling descriptors. Principal component analysis (PCA) is employed to select strongly correlated features and then reduce the feature space dimensionality. The first principal component is used to quantify the intensity of fabric pilling. The results of experimental studies confirm that this method can determine the intensity of pilling. Unlike traditional methods of pilling assessment, it can also detect pilling in its early stages. The approach could help to prevent overestimation of the degree of pilling, thereby avoiding unnecessary procedures, such as mechanical removal of entangled fibers. However, the research covered a narrow group of fabrics and wider conclusions about the usefulness and limitations of this method can be drawn after examining fabrics of different thickness and chemical composition of fibers.

Comfort Criteria

Owing to the slenderness and lightness of most modern footbridges, vibration serviceability assessment becomes a crucial issue in the design process. As one of the key factors, the vibration comfort criterion has an important influence on the assessment of the final result. However, there is an obvious lack of experimental studies in this field, especially regarding the pedestrians' perception of the induced vibrations. In this study, an experiment was conducted to investigate the pedestrians' perception of human-induced vibrations of footbridges. During the experiment, the subjects walked on a pathway that was mounted on top of a shaking table. By imposing sinusoidal excitations with different amplitudes and frequencies, the experiment aimed to determine the influence of the two factors on the walking people's perception. Based on the data collected, perception scales were proposed for both the vertical and lateral vibrations of the footbridge. The established scales comprise five levels that depend on the acceleration amplitude and the frequency. Finally, a comparison between the proposed scales, existing comfort criteria in the literature and international codes was carried out.

This study examines college students’ impressions of accountants from various sources. It extends previous research on students’ impressions of accountants by analyzing impressions after Enron, gender differences in impressions, and the effect of knowledge on impressions and adding news reports as an impression source. Students rated their impressions of accountants when they selected a major on each of 30 characteristics (such as ethical, versatile, and exciting) from each of four sources, plus a general rating. When qualities were combined into two factors, Professionalism and Personability, accountants were seen as professional, but not particularly personable. In many areas, finance majors had impressions of accountants equal to or higher than those of accounting students, while other majors had significantly lower impressions of accountants. News reports did not significantly influence students’ views of accountants. Knowledge was strongly correlated with impressions. Accounting students had the lowest knowledge of accountants from news reports and movies/TV of any major. Females held more positive impressions of accountants than did males. Implications for various groups, including college and high school accounting education and the accounting profession, are discussed.
