Heritage institutions, as one of the main aspects of culture, play an important role in economic prospect of culture by promoting tourism industry. Turning to the interpretation of culture in economic terms, the goal of this paper is to adopt a practical evaluation tool in order to assess the efficiency of heritage institutions. This study evaluates the technical efficiency of a regional system of museums in Tehran, the capital of Iran, using Data Envelopment Analysis approach. The findings may prove useful for management of these institutions in economic point of view, as well as for those responsible for public resource allocation policies in the area of cultural heritage. 相似文献

Trace metals are beneficial nutrient materials that act as essential cofactors in physiological processes. Recent evidence suggests that increase or decrease in certain trace metals may be related with risk and development of chronic diseases such as cancer. This study analyzed some trace elements level in hair and nail of patients with stomach cancer, and compared with their level in healthy controls. Trace elements (Cu, Fe, K, Li, Mg, Mn, Na, P, Se, Sr and Zn) are estimated in hair and nail of the 73 cancer patients and 83 controls by atomic absorption spectrophotometric method. The levels of Cu, K, Li, P and Se in hair and nail samples, were significantly higher in cases than controls. Levels of Mg and Sr were significantly lower in cases than controls. Fe level in hair samples was significantly higher in cases than controls. The mean concentrations of Fe, Se and P significantly increased with increasing cancer stage in the hair of patients. The average concentration of k also significantly increased with increasing cancer stage in the nail of patients. The results of our study show that there is an association between the increase in Cu, K, Li, P, Se and Fe, and stomach cancer development. Our results reveal that the increase in the trace elements could be a potential diagnostic marker to predict cancer progression and its etiology. 相似文献

ABSTRACTGlobally, young people experience physical, sexual and emotion abuse within their intimate relationships. There is a need to explore creative, participatory sexual and relationship education that provides spaces for critical reflection regarding gender norms and approaches within intimate relationships. This study explores an interactive theatre intervention aimed at uncovering and analysing social and cultural influences affecting experiences and approaches within intimate relationships among young people in Samoa. Focus groups were conducted with the audience before and after a public, interactive theatre production. Focus groups aimed to capture shifts in understandings and perceptions as well as overall experiences related to participating in the production. Post production, participants showed a deepened of understandings related to social and cultural factors influencing approaches and actions within intimate relationships. Participants engaged in dialogue around new possible approaches to initiating and maintaining intimate relationships free from violence. Embodied learning opportunities appeared to contribute to feelings of empowerment to try out new responses in everyday life. Study findings highlight a role for drama in intimate relationship education and advocate for the inclusion of intersectionality informed approaches that uncover diversity within a group and acknowledge interactions between individuals’ social position(s) within complex social and cultural contexts. 相似文献

The aim of this study was to investigate effects of speed and plane of motion on stability during locomotion in skilled football players. Ten male national-level football players participated in this study to run forward, backward and in lateral directions on a treadmill at 80%, 100% and 120% of their preferred running speeds. The coordinate data of passive reflective markers attached to body segments were recorded using motion capture systems. Time series data obtained from the ankle marker were used for further analyses. The largest finite-time Lyapunov exponent and maximum Floquet multiplier were adopted to quantify local and orbital dynamic stabilities, respectively. Results showed that speed did not significantly change local and orbital dynamic stabilities in any of running patterns. However, both local and orbital dynamic stability were significantly higher in the secondary plane of progression. Data revealed that in running, unlike walking, stability in the direction perpendicular to the direction of running is significantly higher, implying that less active control is required in the secondary plane of progression. The results of this study could be useful in sports training and rehabilitation programmes where development of fundamental exercise programmes that challenge both speed and the ability to maintain stability might produce a tangible enhancement of athletic skill level. 相似文献
