    Illness Experiences among Chinese College Students: A Negotiation Process between Social Connections and Protection of Self-Image

    Get PDF
    This study explored the experience of illness in relation to self-image, biographical disruption, and the process of coping through semi-structured interviews with students of a university in China. Twelve students were recruited under three categories, having a physical chronic illness, mental health illness, and chronic multiple morbidities. Indepth interviews were conducted and content analyses were applied to their recordings to identify major themes and subordinate themes in the illness experience. Results showed a distorted sense of self and biographical disruptions in young adulthood were common, as reported by the respondents. Students tried to cope with these disruptions with both individual strengths and social support, but not always with positive results. Reconstruction of self, in the analysis of illness experiences, was found a crucial strategy in overcoming disruptions. Social support of evaluative nature facilitated the adoption of the reconstruction strategy. A network-building approach is recommended for student services in higher education whereas further research is necessary to understand the processes of self-reconstruction

    建立了同位素稀释技术与IC-MS 相结合的ID-ICP-MS 分析方法, 成功测量了取自南海北部的滨珊瑚样品中的微量铀, 获得0.5% 左右的精度。并以此建立南海北部近岸海域的珊瑚U/Ca 温度计, 其温度精度可达士0.5 ℃。ID-ICP-MS, an analytical method that combines isotope dilution technique and ICP-MS method had been developed in our laboratory. Trace uranium of the coral samples from the northern area of the South China Sea had been measured to an accuracy of 0.5%. Depended on these results, a high resolution coral U/Ca thermometer for thes area was established. Monthly average SSTs with a precision of ±0.5℃ were attainable by this U/Ca thermometer.published_or_final_versio

    Capacitated Center Problems with Two-Sided Bounds and Outliers

    In recent years, the capacitated center problems have attracted a lot of research interest. Given a set of vertices VV, we want to find a subset of vertices SS, called centers, such that the maximum cluster radius is minimized. Moreover, each center in SS should satisfy some capacity constraint, which could be an upper or lower bound on the number of vertices it can serve. Capacitated kk-center problems with one-sided bounds (upper or lower) have been well studied in previous work, and a constant factor approximation was obtained. We are the first to study the capacitated center problem with both capacity lower and upper bounds (with or without outliers). We assume each vertex has a uniform lower bound and a non-uniform upper bound. For the case of opening exactly kk centers, we note that a generalization of a recent LP approach can achieve constant factor approximation algorithms for our problems. Our main contribution is a simple combinatorial algorithm for the case where there is no cardinality constraint on the number of open centers. Our combinatorial algorithm is simpler and achieves better constant approximation factor compared to the LP approach
