关爱农村“留守儿童”

“留守儿童”是我国社会转型时期的一个特殊群体,他们的父母外出经商、务工,把他们留在原住地交给其祖辈或其它亲属照料,这部分儿童由于长期得不到父母面对面的教育、关爱,存在严重的监护缺失、教育滞后、心理病态发展等问题。笔者认为应以学校寄宿制为主导,家庭、政府和社会多方面力量协调作用,营造关爱留守儿童的社会氛围,构筑起面向留守儿童的一套完备的社会化服务体系。     

自然文化遗产资源与经济发展

在全球化的进程中,自然文化遗产的经济价值明显地提升了,其经济价值和其他价值之间的矛盾也变得越来越突出。如果能够有效地利用自然文化遗产资源的比较优势来发展旅游业,就可以实现自然文化遗产所在地经济良性增长的目标,并使环境资源冲突与环境代价降到最低限度。因此,我们必须重新认识自然文化遗产保护与经济发展之间的关系。既要重视自然文化遗产资源在经济与社会可持续发展中的作用,更要在开发与利用的同时,充分认识到这种珍贵而稀缺资源的脆弱性及其不可再生性,切实采取有效的措施保护其安全和延续。     

《红楼梦》中的疾病主题

文学中的疾病主题已超越了疾病的医学意义,具有社会、政治、经济、文化及美学意义,而且也被赋予了某种叙述功能。疾病主题在《红楼梦》中的地位和作用达到了登峰造极的地步,是《红楼梦》塑造人物形象的重要手段。在其叙述过程和结构中,病场景和病本身成为一个构成整体结构和突出表现作者意旨的有效策略。

Rationalization in garages in the Netherlands and its effects on occupational health

In this study, various hypotheses were tested in relation to car mechanics working in a sample of domestic car garages in South Limburg, The Netherlands. These concerned the negative relationships between the degree of control over the work process, and occupational strain, blood pressure, skin disorders and problems in the locomotor system. The relevant intermediate variables used were task latitude, social support from supervisor and colleagues, and positive appreciation (which were expected to weaken the major hypothesized relationships), and time pressure, mental load, and involuntary task interruption (which were expected to strengthen the major hypothesized relationships). The analysis also included the possible effects of age and seniority. Controls based on craft methods, blood pressure and skin disorders were measured through observation. The effect of controls based on craft methods, and occupational strain were demonstrated. Effects were also shown of occupational strain on diastolic blood pressure and on problems in the locomotor system, and of positive appreciation on non-contact skin disorder.

用ｐＨ法测定了镧和天门冬氨酸在水—二甲基亚砜、钕和甘氨酸在水—二氧六环混合溶剂中的配位常数．测定精度为±０．０１ｐＨ单位．通过加入一定量硝酸钾溶液维持溶液的离子强度（０．１０ｍｏｌ／Ｌ）．测定时采用氮气氛保护并保持温度变化不超过±０．２Ｋ．利用配位常数计算了这些配合物在混合溶液中的△Ｇ°、△Ｈ°和△Ｓ°．     

禽康灵对鸡防病助长的效应观察

禽康灵为纯中药复方制剂,对鸡具有防病助长的作用。试验表明,应用禽康灵的鸡发病率、死亡率均低于空白对照组,分别低25.22％、11.17％;试验中,试验组各批各小组平均体重较空白对照组多增重24.5g、91.0g、108.0g、10.5g、24.3g和61.2g。     

养殖户动物疫病防控激励研究进展

梳理国内外养殖户层面动物疫病防控激励研究进展,现有文献从经济和非经济因素分析养殖户防控激励。其中,经济因素包括内部和外部经济激励,内部经济激励来自防控措施对疫病损失的规避效果;养殖户疫病防控的外部性产生了公共政策干预和养殖户之间策略互动两类外部经济激励。非经济激励包含对疫病、风险和补偿的认知和态度,以及文化、声誉和责任感等因素。当前我国疫病防控政策对养殖户的经济激励重视不足、外部和内部经济激励错配,加之没有考虑非经济激励的营造与构建,是造成养殖户防控要素投入不足、疫情隐瞒等公共政策激励不相容的原因。针对动物疫病防控政策的缺陷,从经济与非经济激励两方面提出了矫正建议。     

CagA阳性幽门螺杆菌感染与消化性溃疡、胃炎相关性512例临床分析

目的：探讨CagA阳性Hp感染与消化性溃疡、胃炎等胃及十二指肠疾病的关系.方法采用ELISA法对Hp阳性(13 C-呼气试验为阳性)、胃黏膜快速尿素酶联免疫法阳性的512例胃十二指肠疾病患者及80例对照者(健康体检：13 C-呼气试验为阴性、胃黏膜快速尿素酶联免疫法阴性)行血清CagA抗体检测.512例胃十二指肠疾病患者中慢性浅表性胃炎(CSG)184例,慢性萎缩性胃炎(CAG)120例,十二指肠球溃疡(DU)100例,胃溃疡(GU)108例.结果 CagA抗体阳性检出率对照组为30%,慢性浅表性胃炎组阳性率为61.96%,慢性萎缩性胃炎组阳性率为63.33,十二指肠溃疡组阳性率为68.00%,胃溃疡组阳性率为74.07%.胃十二指肠疾病患者CagA阳性总检出率为66.02%,与对照组比较,差异具有统计学意义(P<0.05).结论胃十二指肠疾病Hp阳性感染者中CagA抗体阳性总检出率明显高于对照组,提示CagA抗体阳性感染与胃十二指肠疾病密切相关;两组胃炎患者CagA抗体阳性检出率明显高于对照组,提示CagA抗体阳性感染与胃炎密切相关;胃十二指肠溃疡患者CagA抗体阳性检出率明显高于对照组,提示CagA抗体阳性感染与消化性溃疡密切相关.     

A flexible multi‐domain test with adaptive weights and its application to clinical trials

The design of a clinical trial is often complicated by the multi‐systemic nature of the disease; a single endpoint often cannot capture the spectrum of potential therapeutic benefits. Multi‐domain outcomes which take into account patient heterogeneity of disease presentation through measurements of multiple symptom/functional domains are an attractive alternative to a single endpoint. A multi‐domain test with adaptive weights is proposed to synthesize the evidence of treatment efficacy over numerous disease domains. The test is a weighted sum of domain‐specific test statistics with weights selected adaptively via a data‐driven algorithm. The null distribution of the test statistic is constructed empirically through resampling and does not require estimation of the covariance structure of domain‐specific test statistics. Simulations show that the proposed test controls the type I error rate, and has increased power over other methods such as the O'Brien and Wei‐Lachin tests in scenarios reflective of clinical trial settings. Data from a clinical trial in a rare lysosomal storage disorder were used to illustrate the properties of the proposed test. As a strategy of combining marginal test statistics, the proposed test is flexible and readily applicable to a variety of clinical trial scenarios.
