| 1 | Biological responses of small yellow croaker(Larimichthys polyactis) to multiple stressors: a case study in the Yellow Sea, China显示文摘Temporal changes in biological characteristics of small yellow croaker Larimichthys polyactis in the Yellow Sea were examined for the period of 1960–2008. The body size and age of small yellow croaker decreased substantially, in particular, average length of fish in 2008 was reduced by ~85% than those occurring in 1985, and at that time ~93% of the total catch was dominated by one-year-old individuals. Correspondingly, growth parameters also varied significantly over the years, i.e., k(growth coefficient) and t_0(zero-length age) gradually increased from 0.26 and –0.58 year in 1960 to 0.56 and –0.25 year in 2008, respectively. Although, L∞(body length)sharply decreased from 34.21 cm in 1960 to 24.06 cm in 2008, and t_r(inflexion age) decreased from 3.78 year in1960 to 1.61 year in 2008. There was a great increase both in natural mortality coefficient and fishing mortality coefficient. However, according to the gray correlation analysis, changes in the biological characteristics of small yellow croaker were induced by different stressors ranked as: fishing vessel power>feeding grade>sea surface temperature. This study suggests that the active fishery management measures for biological characters of fish populations should be considered. | SHAN Xiujuan LI Xiansen YANG Tao SHARIFUZZAMAN S M ZHANG Guozheng JIN Xianshi DAI Fangqun | 2017 | Acta Oceanologica Sinica2017，36，10： | 5 |

| 3 | Comparative study of mechanical and wear behavior of Cu/WS_2 composites fabricated by spark plasma sintering and hot pressing显示文摘The mechanical and wear behavior of copper-tungsten disulfide(Cu/WS_2) composites fabricated by spark plasma sintering(SPS) and hot pressing(HP) was investigated, comparatively. Results indicated that the addition of lubricant WS_2 substantially reduced wear rate of the Cu matrix composites fabricated by SPS,and the optimum content of WS_2 is 20 wt% with regard to the wear behavior. However, it affected a little to the wear rate while dramatically decreased the friction coefficient of the composite fabricated by HP.This difference in friction behavior of the self-lubricating composites fabricated by the two techniques was closely related to their different mechanical properties. Severe interfacial reaction occurred during spark plasma sintering, leading to brittle phase formation at interface. | Qunchang Wang M inghui Chen Zhongmao Shan Chengguo Sui Lin Zhang Shenglong Zhu Fuhui Wang | 2017 | Journal of Materials Science & Technology2017，33，11： | 3 |
| 4 | Medical student depression and its correlates across three international medical schools显示文摘BACKGROUND Medical students have high rates of depression, anxiety, and burnout that have been found to affect their empathy, professional behaviors, and performance as a physician. While studies have examined predictors for burnout and depression in the United States (US), no study, to our knowledge, has compared depression in medical students cross-culturally, or has attempted to examine the effect of factors influencing rates including burnout, exercise, stress, unmet mental health needs, and region. AIM To examine rates of depression in three international cohorts of medical students, and determine variables that may explain these differences. METHODS Convenience samples of medical students from three countries (US, China, and a Middle Eastern country whose name remains anonymous per request from the school) were surveyed in this observational study. Using the Patient Health Questionnaire-2 (PHQ-2) and a modified Maslach Burnout Inventory, depression and burnout were examined among medical students from the three cohorts (n = 473). Chi-square test and analysis of variance were used to examine differences in demographics, behavioral, and psychological variables across these three schools to identify potentially confounding descriptive characteristics. Analysis of covariance compared depression and the emotional exhaustion component of burnout identified through Principal Component Analysis across countries. Multiple linear regression was used to analyze the impact of demographic, behavioral, and psychological variables on screening positive for depression. RESULTS Medical students from the Middle Eastern country had the highest rates of positive depression screens (41.1%), defined as a PHQ-2 score of ≥ 3, followed by China (14.1 %), and then the US (3.8%). More students in the Middle Eastern school had unmet mental health needs (50.8%) than at the medical school in China (34.8%) or the school in the US (32.8%)(Pearson chi-square significance < 0.05). Thus, PHQ-2 scores were adjusted for unmet mental health needs;however, the Middle Eastern country continued to have the highest depression. Adjusting for PHQ-2 score, medical students from the US scored the highest on emotional exhaustion (a measure of burnout). Demographic variables did not significantly predict medical student depression;however, lack of exercise, unmet mental health needs, stress, and emotional exhaustion predicted nearly half of depression in these cohorts. In comparison to the US, coming from the Middle Eastern country and China predicted higher levels of depression. CONCLUSION Depression rates differ in three international cohorts of medical students. Measured factors contributed to some observed differences. Identifying sitespecific prevention and intervention strategies in medical student mental health is warranted. | Jessica A Gold Xinran Hu Gan Huang Wan-Zhen Li Yi-Fan Wu Shan Gao Zhe-Ning Liu Mickey Trockel Wan-Zhen Li Yi-Fan Wu Shan Gao Zhe-Ning Liu Robert M Rohrbaugh Kirsten M Wilkins | 2019 | World Journal of Psychiatry2019，9，4： | 2 |
