The aim of this research was to study five groups (18 to 26 years old) in order to identify the main motivational factors that influence participation in outdoor activities. A triangulation method, including open-end questionnaires, unstructured conversation and participant observation was employed for investigation.

Five main categories of motivational themes appeared to trigger both female (n=81) and male (n=27) Romanian students participation in outdoor activities. These include the opportunity to enjoy and have fun; to meet new friends and interact; to escape from daily routine and family; to enjoy natures beauty and to explore unknown territories. Female and male students attached a slightly different importance to each of the above motives. It was also found that these motives determine, to an extent, the decision for initial engagement in activities but when it comes to systematic participation the particular situational factors are also very important.  相似文献

There is a vast body of literature on survivors of political violence that has emerged over the past several decades. Most studies focus on the psychological effects of political violence on survivors, as understood within the Western framework of mental health. Studies that conceptualize and examine models that account for the complexity of the ecology of political violence are scarce. This paper synthesizes current conceptual and empirical findings about survivors of political violence. Interventions stemming from an ecological framework are also reviewed.  相似文献

Recent studies have shown that there are systematic differences among total and free prostate-specificantigen (PSA) immunoassays. In this study we analyzedintermethod differences in total PSA (tPSA) and free PSA(fPSA) measurement using ARCHITECT i2000SR (Abbott Diagnostics) and COBAS E601 (Roche Diagnostics). A number of 160 blood samples were tested for tPSA and 50 samples for fPSA (selecting only sampleswith tPSA: 4.1–10.0 μg/L). Passing–Bablok regression analysis was used to compare the two analytical methods fortPSA, fPSA and percentage of fPSA (%fPSA). A strong correlation was noticed between ARCHITECT i2000SR and COBAS E601 for tPSA, fPSA and %fPSA (r between 0.94 and 0.99). Concentrations of tPSA and fPSA measured by COBAS E601 were higher thanthose measured by ARCHITECT i2000SR with a bias of 0.8 μg/L for tPSA and 0.14 μg/L for fPSA. Analyzing therelative difference between methods for fPSA and %fPSA, COBAS E601 exceed a 10% relative difference limit. Our study confirms that there are differences in measured concentrations of tPSA and fPSA byvarious commercial methods. Because clinical judgment on subsequent diagnostic procedures, such as prostatebiopsy, is based on tPSA and fPSA results, tests harmonization should be a priority.  相似文献
