Laboratory-based simulators afford many advantages for studying physiology and biomechanics; however, they may not perfectly mimic wheelchair propulsion over natural surfaces. The goal of this study was to compare kinetic and temporal parameters between propulsion overground on a tile surface and on a dynamometer. Twenty-four experienced manual wheelchair users propelled at a self-selected speed on smooth, level tile and a dynamometer while kinetic data were collected using an instrumented wheel. A Pearson correlation test was used to examine the relationship between propulsion variables obtained on the dynamometer and the overground condition. Ensemble resultant force and moment curves were compared using cross-correlation and qualitative analysis of curve shape. User biomechanics were correlated (R ranging from 0.41 to 0.83) between surfaces. Overall, findings suggest that although the dynamometer does not perfectly emulate overground propulsion, wheelchair users were consistent with the direction and amount of force applied, the time peak force was reached, push angle, and their stroke frequency between conditions.

This research assesses the relationship between intercultural exposure variables—the length of time spent in the United States, the length of previous experience outside Saudi Arabia, the length of time studying English as a second language, and the frequency and nature of interactions with Americans—and intrapersonal identity conflict. To assess this relationship, the researcher conducted a survey of Saudi Arabian students studying in the United States, which collected information on exposure variables, as well as employing Leong and Ward’s (2000) Ethno-Cultural Identity Conflict Scale (EICS). A Pearson correlation test was conducted to examine the relationship between the Saudi sojourners’ intercultural exposure and their identity conflict scores to conclude that there is not a relationship between exposure and identity conflict.

<p><strong>INTRODUCTION:</strong> Academic burnout leads to creation of a series of negative and scattered thoughts, loss of hope and emotional and physical exhaustion in carrying out activities. Two factors that affect academic burnout are sleep quality and social intimacy. This study was conducted in order to investigate the relationship between sleep quality and social intimacy, and academic burn-out in the students of Tabriz University of Medical Sciences</p><p><strong>MATERIALS &amp; METHODS: </strong>This study was descriptive and correlational. The population of this study consisted of the students in Tabriz University of Medical Sciences and 196 medical students were selected. They completed Berso et al. Academic Burnout Questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Miller Social Intimacy Scale (MSIS). The validity of the questionnaires confirmed by experts’ views. Their reliability were obtained as 77%, 64% and 85% for academic burnout, sleep quality and social intimacy questionnaires respectively by calculating the internal consistency (Cronbach’s alpha). For data analysis, descriptive statistics and Pearson correlation test, Regression, cluster analysis and t-test were used.</p><p><strong>RESULTS:</strong> The results showed that there was a positive and significant relationship between sleep quality and academic burnout at the level p&lt;0.05 (r=0.38). There was a negative and significant relationship between social intimacy and academic burnout at the level p&lt;0.05 (r= -0.40). Also, the regression results showed that sleep quality and social intimacy were able to predict 37% and 39% of academic burnout respectively. Moreover, the students were divided into two clusters of individuals with high social intimacy and individuals with low social intimacy. No significant difference was found between the two types in terms of the variable of academic burn-out.</p><p><strong>CONCLUSION:</strong> Based on the research results, it can be stated that the variables of sleep quality and social intimacy are the predictor factors of academic burn-out.</p>
