On the promise and perils of citizenship: heuristic concepts,Zimbabwean example

Increasingly, struggles in the name of citizenship inspire and catch the imagination and support of individuals and groups found in a variety of locales within a nation as well as transnational spaces. At the same time, their consequences may be quite different from the assumptions and dreams of those involved in perpetuating and imagining these struggles. To analyse how new social citizenship claims can embolden and channel struggles in particular directions with varied results – the promise and perils of citizenship more broadly – I suggest that one should pay attention to the promulgators of such visions of citizenship, the techniques of promoting their claims and the cultural politics and political economies of belonging in the locales of mobilization. Drawing on an ethnographic example of a farm labour struggle in the late 1990s in Zimbabwe, I explore the importance of attending to wider shifts in the political importance of citizenship as well as its entanglement in particular localities. Through examining how farm workers are situated through such struggles, I show the promise and limits of citizenship in addressing social justice concerns of a group historically marginalized through racialized, classed and gendered processes.     

我国妇女农地权利法律制度运作的实证研究与完善路径

在我国,保护农村妇女土地权益具有重要意义,但调查研究表明,农村妇女土地权益频受侵害,土地承包经营权并未得到充分的保障。造成这种状况的主要原因:一是我国立法上对"男娶女嫁"婚嫁方式可能损害妇女土地权利的认识不足;二是法律、政策的相关规定互相矛盾;三是立法上对妇女权益法律保护的效果适得其反;四是法律规定过于原则,操作性不强;五是当村规民约侵害妇女土地承包权益时,缺乏有效的法律救济途径;为此,应当有效化解政策、法律之间的冲突,完善细化法律规则,在立法和执法过程中引入社会性别视角,加强对村规民约的法律审查,消除制度歧视。     

限定刑事责任能力评定量表扩展应用的信效度

目的探讨限定刑事责任能力评定量表在责任能力评定中的扩展运用价值。方法采用DCRRS（内容包括现实作案动机,先兆,诱因,时间、地点、对象、工具选择,作案时情绪反应,作案后各种行为表现,生活自理能力、工作学习能力、自知力、现实检验能力损害和自我控制能力等）对108例符合要求的患者进行评定并与专家鉴定结果进行比较。结果DCRRS各条目间及其与总量表分间的相关均具有统计学意义（r=0.145～0.944,P〈0.001）,分半信度为0.868。根据DCRRS参考划界分分组,无、限定和完全责任能力3组间及两两间量表总分均具有显著统计学差异（P〈0.001）。DCRRS与专家鉴定结果一致性较高（Kappa=0.958,P〈0.001）,经判别方程回代具有较高的正确率（97.2%）。结论DCRRS的信效度良好,可作为辅助参考使用。     

猪场环境中大肠杆菌的耐药性检测及其耐药机理

为探讨猪场环境中大肠杆菌的耐药性及其耐药机理,随机选取从规模养猪场环境中分离的31株大肠杆菌,采用药敏纸片法检测其耐药性、PCR法检测其qnrA和aac(6’)-Ib基因存在状况,然后采用高温-SDS法对其中1株分离菌进行耐药质粒消除试验。结果显示,所分离的31株大肠杆菌对青霉素、四环素、洁霉素、红霉素、罗红霉素等抗生素呈现不同程度的耐药性;在所有试验菌株中未检出qnrA基因,而可检出aac(6’)-Ib基因的有8株;通过对含aac(6’)-Ib基因质粒的消除,分离菌株可获得对氨基糖苷类和喹诺酮类抗生素的敏感性。表明猪场环境中的大肠杆菌对临床常用药物产生了广泛的耐药性,而含aac(6’)-Ib基因质粒可介导环境中的大肠杆菌对氨基糖苷类和喹诺酮类抗生素耐药。     

一株致猪胃溃疡大肠杆菌的分离鉴定

四川某猪场暴发保育猪与育肥猪水样腹泻,病理剖解可见胃黏膜大面积脱落、胃溃疡等症状,采集病死猪扁桃体与肠系膜淋巴结进行病毒检测;以肠内容物做寄生虫卵检测;选取其中一代表病例做细菌分离,经小鼠致死试验、仔猪回归试验确定病原菌,并对病原菌进行了形态学观察、生化鉴定、16SrDNA序列分析及药敏试验。结果显示,猪瘟病毒、伪狂犬病病毒等的检测结果为阴性;无寄生虫感染;从十二指肠内容物中分离到1株疑似致病性大肠杆菌,并命名为SCDC-1。用SCDC-1株人工感染健康仔猪成功复制出水样腹泻、胃溃疡病例。对SCDC-1株进行16SrDNA克隆测序,并与GenBank中的8株肠杆菌科和4株巴氏杆菌科菌株的16S基因进行同源性分析,发现SCDC-1株与大肠杆菌16S基因的相似性高达99.5%～99.9%。药敏试验结果显示,该病原菌仅对头孢曲松钠、头孢吡肟、丁胺卡那霉素敏感。试验结果证实,引起此次保育猪与育肥猪胃溃疡的主要病原为致病性大肠杆菌。     

燃煤污染型氟中毒病区儿童智力调查及法医学意义

目的探讨燃煤污染型氟中毒病区8～12岁儿童智力水平及其与染氟量之间的关系,为慢性氟中毒致中枢神经损伤的相关研究提供人群数据资料,为氟病区人群智力残疾鉴定提供修正参考值。方法采用《中国修订韦氏学龄期儿童智力量表(WISC-CR)》测试99名8～12岁小学生(包括氟斑牙组55人,对照组44人)的智力水平,比较氟斑牙组与对照组儿童智力水平差异,并对染氟儿童智力水平与染氟量之间的相关性进行分析。结果氟斑牙组的言语智商(85.64±16.53)、操作智商(94.87±12.73)、总智商(88.51±12.77)均低于对照组(言语智商94.34±16.04、操作智商99.23±12.44、总智商96.64±11.70),其中,两组的言语智商和总智商差异有统计学意义(P=0.002,P=0.01)。氟斑牙组与对照组的言语智商中各项分测验均显著低于对照组,差异有统计学意义(P<0.05)。操作智商中各项分测验除积木测验和译码检测外,差异有统计学意义(P<0.05)。结论燃煤污染型氟中毒儿童可出现智力损害,对言语智力的损伤较为明显;对患儿进行智力残疾鉴定时,应考虑修正智力评测的结果。     

Precariousness or prosperity? The diverse faces of widowhood in rural Buenos Aires during the nineteenth century

In this article, I will explore the resources and capacities women could mobilize in the countryside of Buenos Aires at the beginning of the nineteenth century when they had to confront the domestic crisis triggered by their husbands’ death. It is of course essential to study the foreseeable options (taking over the helm of the family farm, seeking refuge with relatives, or quickly remarrying) they had and the role played by what are commonly considered as crucial resources (family composition, patrimony, and networks). This study nevertheless seeks to identify other factors (notably the legal framework, patterns of colonization, and widows’ own know-how and experiences as farmers and settlers) that bring to light the specificity of widowhood in rural Buenos Aires during this period. As a consequence, the juridical aspects of inheritance proceedings and the concrete practices they reveal will be analyzed before I examine the wide social spectrum (namely the inhabitants of San Antonio de Areco, La Matanza, Quilmes, and San Vicente, four areas of rural Buenos Aires) registered by the censuses of 1813 and 1815.     

论声纹鉴定意见的表述形式

本文针对目前国内外讨论比较热烈的声纹鉴定意见表述问题进行了评述.首先介绍了实践中正在使用的听觉分析法、声谱比对分析法、声学分析法、听觉-声学分析法和说话人自动识别五种鉴定方法,指出了各种方法的优缺点;然后对现存的二元判决、可能性等级、似然比和英国立场声明四种鉴定意见表述形式进行了介绍和评析,通过分析发现,上述四种意见表述形式都存在一定的问题,实践中选择何种形式表述鉴定意见要综合考虑其科学性、逻辑性、现实性和可行性等多种价值选项;最后认为解决该问题的根本方法是各相关领域的专家应加强在鉴定方法上的合作性的基础研究.     

Probabilistic Classification of Age by Third Molar Development: The Use of Soft Evidence

Abstract: This study introduces a method to classify individuals according to an age threshold, given sex and third molars’ dental maturity measured on the Demirjian scale by expressing uncertainty on dental evidence (soft evidence). We introduced a procedure to learn the parameters of the Naïve Bayes model, and we discussed two classification rules. The model was estimated and tested on 559 Italians aged 16–22. Two experts provided the dental evaluations, and the model was estimated for each of them. We evaluated the coherence of the evidence provided by the experts. Some indexes have been proposed to evaluate the effectiveness of the models, emphasizing how the experts’ ability and the technology affect the results. We introduced two benchmarks, one based on the sample distribution per sex and age: in this case, probability of correct classification increases 22% and the proportion of false adults impressively decreases 80.2%; the other benchmark, obtained by simulating hard evidence, shows how the use of soft evidence increases the proportion of correct classification 3.1% and decreases the crucial proportion of false adults about 20%. Similarly, the proportion of false minors decreases about 5.3%.
