煤矿一线员工过度劳动评价与影响因素 —— 基于四个省份十二个煤矿调查数据的分析

基于四个省份十二个煤矿一线员工的问卷调查数据，采用相关性分析和多元回归分析的方法， 从个人、家庭、企业、工作四方面，探究了我国煤矿一线员工过度劳动影响因素。研究发现：经济利益、自我发展、 家庭责任、不和谐的家庭关系、考核标准、薪酬制度、企业文化、工作量、工作要求、工作环境对煤矿一线员工 过度劳动的产生具有显著的正向影响，家庭支持对煤矿一线员工过度劳动的产生具有显著的负向影响。不同年龄、 不同工龄、不同收入的员工，过度劳动程度存在显著差异。年龄越大、工龄越长、收入越高的员工过劳程度更高。 总体上看，煤矿一线员工普遍存在过度劳动且较为严重。     

How to share and utilise expertise in a police forensic department through externalisation and mutualisation

The technique of fire investigation is a forensic domain in which expertise and analogies play a central role. To learn how fire investigators use these analogies to support their work, we conducted an ethnographic study in a Swiss forensic police department. To propose a suitable knowledge-management strategy, we also evaluated the knowledge conservation and sharing within the department. Our results highlighted that actionable knowledge is registered mainly in the investigators’ memories of a few, very experienced, individuals. Without experience with fire-incident investigations, an agent generally requires help from a more experienced colleague, who will then use his memory to find a similar case, which can contribute to the solution of the ongoing one. The research also established that knowledge is exchanged orally during on-site investigations and that knowledge receivers are generally those who are present on the scene. Using these findings, we suggest building a case library to support the externalisation and sharing of knowledge.     

跨境民族因素对阿巴边境地区毒品问题的影响

随着1979年苏联入侵阿富汗和阿富汗抗苏战争的开展,阿富汗和巴基斯坦边境地区的罂粟种植面积迅速扩大,毒品产量迅速增加,成为世界毒品市场的重要来源地。阿巴边境地区的普什图人和俾路支人等跨境民族在"金新月"地带的罂粟种植和毒品生产中扮演着重要的角色。20世纪80年代后,阿富汗生产的鸦片主要来源于阿巴边境的普什图人村庄,巴基斯坦的罂粟种植也主要集中在以普什图人为主的西北边境省和联邦直辖部落地区。多年以来,尽管阿富汗和巴基斯坦政府在阿巴边境地区不断采取禁毒措施,发展替代种植,但是均未能清除该地区的罂粟种植和毒品生产。阿巴边境的普什图人、俾路支人等民族长期种植罂粟并参与毒品走私的原因包括历史、政治和经济等因素。从历史上看,阿巴边境的普什图人有种植罂粟的传统,出售鸦片是他们重要的经济来源之一。从政治上看,阿富汗和巴基斯坦两国政府不能对边境地区进行有效的管理和控制,从而为边境地区的普什图人和俾路支人种植罂粟和从事毒品走私提供了条件。此外,一些政党为了拉选票而支持当地人们种植罂粟也是重要的政治原因。从经济上看,种植罂粟的收入要高于种植小麦的收入,贩卖毒品的利润较高是吸引阿巴边境的普什图人、俾路支人等民族种植罂粟和从事毒品走私的重要原因。     

Hearts, as well as Minds: Wellbeing and Illness among Greek Cypriot Refugees

Recently the psycho-social health of refugees has rightly receivedemphasis, but the physical health of long-term refugees warrantssimilar attention. This paper uses qualitative and quantitativedata on informant-reported health outcomes for two Greek Cypriotvillage cohorts, one displaced, the other not displaced. Supplementarydata from a national diabetes prevalence study confirmed a possiblelink between refugee status and greater probability of cardiovascularillness. Depressive illness also seemed higher among the refugeevillage cohort. But it is not only the illness of some of theserefugees, but their surviving this, and the comparative wellnessof others which is important, compared with the ‘demographicshock’ victims of post-socialist Europe, 1989–1995.The paper suggests why the Greek Cypriots have done rather betterin health terms than the post-socialists of Eastern Europe,1989–1995, but argues that refugees in failing statesmay have much worse health outcomes.     

湖北省禽白血病自然病例的病理学诊断及p53和Bcl-2基因表达情况的观察

应用组织病理学和SABC免疫组织化学技术,对湖北省武汉市的2批14日龄和33日龄疑似禽白血病肉鸡进行了病理学诊断,并观察了病鸡肝肿瘤组织中p53基因和Bcl-2基因的表达情况。剖检可见病鸡肝、肾、脾均不同程度肿胀,组织病理学检查在肝、肾、心等脏器可见散在或聚集成团的骨髓瘤细胞,胞浆内充满球形的嗜酸性颗粒;在病鸡肝肿瘤组织中p53和Bcl-2基因均呈阳性表达,诊断为J亚群禽白血病(ALV-J),提示p53基因和Bcl-2基因与肉鸡J亚群禽白血病有关。     

A Test of Generalizability of the Social Development Model Across Gender and Income Groups with Longitudinal Data from the Elementary School Developmental Period

The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.     

Intimate Partner Violence in Extremely Poor Women: Longitudinal Patterns and Risk Markers

Despite high revalence rates of intimate partner violence in the lives of extremely poor women with dependent children, few studies have investigated the patterns of violence that occur over time, and the characteristics of women that serve as risk markers for partner violence. This paper describes patterns of domestic violence longitudinally and uses multivariate analyses to delineate childhood and adult risk markers for recent intimate partner violence in this population of women. Analyses draw upon a sample of 436 homeless and extremely poor housed mothers receiving welfare, in a mid-sized city in Massachusetts with a large Hispanic population of Puerto Rican descent and relatively fewer Blacks. We found that among women with complete longitudinal data (N=280), almost two-thirds experienced intimate partner violence at some point during their adult life by the end of study follow-up, and that the abuse before and after the baseline interview was episodic and limited over time. To examine the role of individual women's factors, while controlling for partner characteristics, we used baseline data on women who had been partnered during the past year (N=336). Among childhood predictors, we found that sexual molestation contributed most significantly to adult intimate partner violence that occurred during the past year prior to the baseline interview. Adult risk markers included inadequate emotional support from non-professionals, poor self-esteem, and a partner with substance abuse problems. Having a partner with poor work history was another independent predictor of recent abuse. Ethnicity did not significantly predict whether women were abused or not during the past year, contrary to other findings reported in the literature.     

胰岛素样生长因子及其受体mRNAs在绵羊生殖系统中的表达和分布

为检测胰岛素样生长因子(IGFs)及其受体(IGFR)mRNAs在绵羊发情周期早期卵巢、子宫和输卵管中的表达,探讨绵羊胚胎早期发育过程中其发育环境——生殖道中生长因子的表达、分泌及其作用,取绵羊发情周期早期卵巢、子宫和输卵管,经固定、切片、免疫染色,观察IGFs mRNAs的表达和分布情况。同时用RT-PCR技术研究了各组织中IGF-Ⅰ、IGF-Ⅱ、IGF-ⅠR、IGF-ⅡR mRNAs的表达情况。结果表明,IGFs mRNAs在绵羊发情周期早期的卵巢、子宫和输卵管中都有表达,4种因子表达模式相似:在卵巢中,IGFs主要定位于卵泡颗粒细胞,间质细胞亦有少量表达。在输卵管中,上皮细胞免疫染色呈阳性;在子宫中,腺细胞及上皮细胞的阳性信号强于固有层。RT-PCR检测表明IGFs mRNAs在3种组织中均有表达。     

影响农民增收的制度因素浅析

农民收入增长缓慢已成为当前农村发展的突出矛盾。农民能否增收与国家支持农业的政策和有关制度有着深层次的联系,政策和制度强烈地影响着农民的经济命运和社会地位。农民增收应改革户籍制度对农民社会地位的隐性限制;农民增收要消除乡村组织制度对农民利益的损益剥夺;农民增收应对的县乡组织制度创新要树立小政府大服务的理念。
