This study examines the role played by individual characteristics and specific treatment methods in the evolution of hospitalized patients with coronavirus disease 2019 (COVID-19), through the lens of an observational study performed in a comparative approach between the first and second waves of coronavirus pandemic in Romania. The research endeavor is configured on a two-fold approach, including a detailed observation of the evolution of 274 hospitalized patients with COVID-19 (145 in the first wave and 129 in the second wave of infection) according to specific treatment methods applied and patients’ individual features, as well as an econometric (quantitative) analysis through structural equation modeling and Gaussian graphical models designed to acknowledge the correlations and causal relationship between all considered coordinates. The main results highlight that the specific treatment methods applied had a positive influence on the evolution of COVID-19 patients, particularly in the second wave of coronavirus pandemic. In case of the first wave of COVID-19 infection, GGM results entail that there is a strong positive correlation between the evolution of the patients and the COVID-19 disease form, which is further positively correlated with the treatment scheme. The evolution of the patients is strongly and inversely correlated with the symptomatology and the ICU hospitalization. Moreover, the disease form is strongly and inversely correlated with oxygen saturation and the residence of patients (urban/rural). The symptomatology at first appearance also strongly depends on the age of the patients (positive correlation) and of the fact that the patient is a smoker or non-smoker and has other comorbidities. Age and gender are also important credentials that shape the disease degree and patient evolution in responding to treatment as well, our study attesting strong interconnections between these coordinates, the form of disease, symptomatology and overall evolution of the patients.

Player Enjoyment

The purpose of this study was to investigate the relationships between gameplay enjoyment, gaming goal orientations, and individual characteristics. A total of 301 participants were surveyed and the data were analyzed using structural equation modeling. This led to an expanded Gameplay Enjoyment Model (GEM) with 41 game design features that influence player enjoyment. Furthermore, a 3x2 Gaming Goal Orientations model was established with six dimensions that describe players' motivations for gaming. In addition, players' individual characteristics were used to predict gameplay enjoyment in the GEM-Individual Characteristics model. The six Gaming Goal Orientations dimensions were the strongest predictors, while the commonly used gender and hours played per week variables failed to predict enjoyment. The results of this study enable important work to be conducted surrounding gameplay experiences and individual characteristics. Ultimately, it is believed that the Gameplay Enjoyment Model, Gaming Goal Orientations, and the GEM-Individual Characteristics model will be useful tools for researchers and designers who seek to create effective gameplay experiences that meet the needs of players.

Co Morbidity

BackgroundClinical trials are typically designed to test the effect of a specific treatment on a single diagnostic entity. However, because common internalizing disorders are highly correlated (‘co-morbid’), we sought to establish a practical and parsimonious method to characterize and quantify changes in a broad spectrum of internalizing psychopathology targeted for treatment in a clinical trial contrasting two transdiagnostic psychosocial interventions.MethodAlcohol dependence treatment patients who had any of several common internalizing disorders were randomized to a six-session cognitive-behavioral therapy (CBT) experimental treatment condition or a progressive muscle relaxation training (PMRT) comparison treatment condition. Internalizing psychopathology was characterized at baseline and 4 months following treatment in terms of the latent structure of six distinct internalizing symptom domain surveys.ResultsExploratory structural equation modeling (ESEM) identified a two-factor solution at both baseline and the 4-month follow-up: Distress (measures of depression, trait anxiety and worry) and Fear (measures of panic anxiety, social anxiety and agoraphobia). Although confirmatory factor analysis (CFA) demonstrated measurement invariance between the time-points, structural models showed that the latent means of Fear and Distress decreased substantially from baseline to follow-up for both groups, with a small but statistically significant advantage for the CBT group in terms of Distress (but not Fear) reduction.ConclusionsThe approach demonstrated in this study provides a practical solution to modeling co-morbidity in a clinical trial and is consistent with converging evidence pointing to the dimensional structure of internalizing psychopathology.

The present research examined the connections between temperament (punishment sensitivity; interindividual reward sensitivity; intraindividual reward sensitivity), students’ domain- and course-specific motivational appraisals (interest, strain, effort), and performance, in two studies. Study 1 explored the relationships between temperamental sensitivities, motivational appraisals, and task achievement among secondary students (N = 268) in the domain of mathematics, using Exploratory Structural Equation Modeling (ESEM) for the analyses. Study 2 was conducted longitudinally among upper-secondary students (N = 155) during a course in four key school subjects. Subject interest was included alongside the temperamental sensitivities as a predictor of course-specific motivation and course grades, and the data were analysed with Partial Least Squares Structural Equation Modeling (PLS-SEM). Previous achievement was controlled in both studies. The findings showed temperamental sensitivities to be differentially linked with motivational appraisals. Punishment sensitivity in Study 1, and interindividual reward sensitivity (sensitivity to reward dependent on others’ approval or attention) in Study 2 were found to have an effect on psychological strain. In both studies, interest and effort were predicted by intraindividual reward sensitivity (positive responsiveness to novelty and own successes). In Study 2, subject interest was a consistent predictor of higher course interest and lower strain. In both studies, connections were found between strain and lower performance. The findings suggest individual characteristics may predispose students to certain motivational experiences, and contribute to educational outcomes, in both domain and course contexts and across subject content.

Development Work

Along with the forming of East Halmahera Regency at 2003, development activities develop rapidly. One of several determining factors of development success is determined by nation apparatus resource. The number of PNS that become the population in this research are employees in the Capital of East Halmahera Regency that isMabaCitywhich total population is 617 persons.           Human resources management influences organizational performance by increasing employee’s commitment that supported by good behavior of all employees. When each employee has commitment, good individual characteristics and good motivation, every employee is hopefully will be able to get working satisfaction and then, these satisfied employee will be able to increase their performance.           In this research, there is 200 employees or 31,32 percent (200/617 x 100%) from the whole population. However, the fact in the field shows that the number of questionnaire as the result of respondents’ answer cannot be tabulated completely, because there is only 194 questionnaire that considered appropriate. It is because 6 of them are destroyed and cannot be interpreted. Sample collection is done by using proportional stratified random sampling technique. Relation among variables in this research is analyzed with SEM (Structural Equation Modeling) with AMOS 4.01 program.          The result of examination to Goodness of Fit Index (GFI) criteria after model is modified shows that confirmatory analysis and structural Equation Modeling in this research can be accepted because of model fit with Chi-square score = 164.94 (critical value < 124.34); GFI = 0,924 (critical value > 0,90); and AGFI = 0,841 (critical value > 0,90). From the result of this research model, it is found out that organizational commitment, career development and work motivation is effective enough when it is used as stimulator of jobb satisfaction and employee’s performance. In other words, work satisfaction and employee’s performance can be improved through organizational commitment, career development; work motivation and individual characteristics. Among organization commitment, career development, work motivation and individual characteristic variables in the forming of jobb satisfaction and employee’s performance, individual characteristic gives the lowest contribution. It shows that individual characteristic is a factor that needs to receive better attention in order to support employee working achievement. Keywords:    organizational commitment, career development, work motivation, individual characteristics, job satisfaction, employee performance, East Halmahera Regency.

This study examined the effect of individual characteristics and transformational leadership on job satisfaction and organizational commitment of the employees at the Department of Islamic Shari'a. The samples were 114 employees. The analytical tool used was Structural Equation Modeling (SEM) using AMOS (Analysis of Moment Structure) tools. The results showed that individual characteristics and transformational leadership affected job satisfaction. Individual characteristics and job satisfaction also significantly affected organizational commitment. However, transformational leadership did not influence organizational commitment. Then, in testing the indirect relationship, job satisfaction did not mediate the effect of transformational leadership on organizational commitment. But job satisfaction fully mediated the effect of individual characteristics on organizational commitment

The Relationship

This study explored the relationship between athletes’ emotion regulation and imagery ability. A total of 648 athletes (57% female; Mage = 20.79 years, SD = 4.36) completed the Sport Imagery Ability Questionnaire (SIAQ) and Emotion Regulation Questionnaire (ERQ). Structural equation modeling supported the hypothesized model in which reappraisal positively predicted all SIAQ subscales. However, suppression had no significant association with imagery ability despite being predicted to be negatively associated. Results support the revised applied model of deliberate imagery use that individual characteristics will influence the imagery experience. Specifically, athletes who reappraise their emotions more frequently find it easier to image sport related content.

True Score

It is shown that a minimal assumption should be added to the assumptions of Classical Test Theory (CTT) in order to have positive inter-item correlations, which are regarded as a basis for the aggregation of items. Moreover, it is shown that the assumption of zero correlations between the error score estimates is substantially violated in the population of individuals when the number of items is small. Instead, a negative correlation between error score estimates occurs. The reason for the negative correlation is that the error score estimates for different items of a scale are based on insufficient true score estimates when the number of items is small. A test of the assumption of uncorrelated error score estimates by means of structural equation modeling (SEM) is proposed that takes this effect into account. The SEM-based procedure is demonstrated by means of empirical examples based on the Edinburgh Handedness Inventory and the Eysenck Personality Questionnaire-Revised.
