ELISA检测精浆特异蛋白P_(30)鉴定人精斑

<正> 1978年美国Sensabaugh分离出精浆特异蛋白P30,并成功的制备出相应的抗P30血清。1987年我国也研制出抗人精浆特异蛋白P30血清,并应用该种抗血清建立了几种琼脂扩散和电泳方法鉴定人精斑。由于人精液中P30含量不高,平均为1.52±0.676mg/ml,鉴定微量精斑存在困难。为了更有效的提高方法的灵敏度。我们建立了鉴定微量人精斑的ELISA固相P30抗体法,现报告如下。     

“入世”与中国的反垄断立法

针对“入世”的形势和国内一些学者的模糊认识 ,本文通过大量的实证分析指出 ,制订《反垄断法》无论从国际层面还是从国内层面均属必需 ,而且 ,立法需考虑这两方面的问题。在此基础上 ,笔者对《反垄断法》的核心问题即垄断的认定问题作了较详细的分析。     

组织学习：管理学视角下的多元理论

就管理学领域中关于组织学习的理论进行了比较系统的研究.在彼得·帕沃夫斯基提出的五大类组织学习理论的分类基础上,进一步对每类理论下各种研究视角和研究思路进行了更为系统的规范分析.主要是对管理学中关于组织学习问题研究的各种理论的缘起、分化、进程及现状进行了系统的分析与评价.研究发现,由于学者们对组织学习的本质的看法、研究视角以及研究范式的不同,使得组织学习问题的研究呈现出理论多元化倾向.但近年来,一些从不同角度研究组织学习问题的理论,又正在趋向于新的整合.认为,关于组织学习问题的更为系统的看法,将建立在关于组织学习本质的多元视角而形成的综合观点基础之上.     

Interpretation,confidence and application of the standardised terms: Identified,Probable, Possible,Exclude and Insufficient in forensic odontology identification

Forensic odontology identification scales are used to express certainty of identifications of deceased persons. These standardized scales are assumed to convey unambiguous expert opinions and facilitate communication between forensic odontologists and end users. However, to date no studies have investigated how the experts interpret and use these scales.Forensic odontology identification scales are used to express certainty of identifications of deceased persons. These standardized scales are assumed to convey unambiguous expert opinions and facilitate communication between forensic odontologists and end users. However, to date no studies have investigated how the experts interpret and use these scales.This paper aims to examine the interpretation of the DVISYS forensic identification scale and choices of the levels in the scale subsequent to, and derived from, comparison of pairs of dental radiographs by extending the analysis of the data collected in the study by Page and Lain et. al. 2017.The studied variables: self-reported confidence, forced binary decision of match and non-match, choice of level in the DVISYS scale (Identified, Probable, Possible, Insufficient and Exclude) were further analysed in this study using mixed models for relationships between the choices of level in the identification scale and the fundamental beliefs of likelihood of identification.The results of this further analysis showed that the reported confidence of the decisions was correlated to the difficulty of cases, and as confidence decreased the use of less definitive terms (‘Probable’, ‘Possible’ and ‘Insufficient’) increased. ‘Probable’ and ‘Possible’ were used mainly in underlying beliefs below that of ‘Identified’ whereas ‘Insufficient’ was used mainly to convey a sublevel of ‘Exclude’. The use of ‘Insufficient’ in this study was not consistent with the prescribed definition of the term.The participants of the original study were not aware of the difficulty grading of the cases nor were required to grade them, however the reported confidence was systematically correlated to difficulty. Furthermore, indicated confidence level was correlated with choice of level on the scale in general, but the interpretation of the definition and application of the terms varied.The findings reported here contribute to the foundational knowledge of factors governing the interpretation and application of the DVISYS forensic odontology identification scale and suggest that this scale may need to be modified.     

元明清王朝治回政策与回族形成

从唐宋元王朝的回族先民到明清王朝的回族,每个王朝的统治者都制定了不同的政策,这些政策的制定与回族的形成有着密切关系。在元代恩威相济的对回政策下,回族共同体雏形形成;明代回回人仍受重用,对回实行优待和强制同化政策,回回人融合汉族文化进而加速了原文化的本土化进程,回族共同体形成;清代对回政策前后有别,前期因俗而治,后期采取“以回制回”的压制政策,回族共同体非但未被削弱,民族认同得到加强。     

医疗损害责任纠纷案件鉴定问题研究——以2018年江苏省审判数据为依据

目的:对医疗损害鉴定问题进行实证研究,探讨医疗损害鉴定实施现状与责任认定情况,为完善我国医疗损害鉴定制度提供依据.方法:采用SPSS22.0软件对2018年江苏省医疗损害责任审判案件进行统计学分析.结论:医疗损害鉴定优先选择医学会鉴定;医疗损害"二元化"鉴定模式并存损害司法公平正义;重复鉴定、多重鉴定增加诉讼成本.对策...     

正常、大声两种说话状态下语音的声学差异及对声纹鉴定的影响

本文主要通过对正常、大声两种说话状态下的普通话中三个单元音[a]、[i]、[u]的声强、时长、基频、谐波振幅差值、共振峰等声学参数的分析,综合比较了各参数的变化规律,发现大声说话时的语音并非正常语音的简单放大,二者不仅在声强上存在差别,同时在频率域上也发生了重要变化。同一人不同状态下发音的频谱特征差异性较大,同种状态下发音的相似性、可比性较强,为此,声纹鉴定中应尽量选取状态相同的语音进行比对。     

东北亚地区的民族国家认同、地区认同与对外认知

认同会对政治的认识与行为带来重要影响。但从国际关系视角对这一问题进行研究尚处于起步阶段。本文就构建东北亚共同体为背景,以韩中日三国为主轴,通过问卷调查的形式,对东北亚地区民族国家认同的强度和影响力,民族国家认同对地区认同的形成以及东北亚国家的对外认识的影响,超国家的接触对国家、地区认同及对外认识的影响等三个问题得出了结论。并认为,韩中日三国均表现出强烈的国家认同,并对地区共同体的形成产生不良影响;东北亚地区存在的否定相互认知,根源在于日本帝国主义的侵略战争。     

IMF staff: Missing link in fund reform proposals

Current IMF reform proposals are preoccupied with changing governance structures by reallocating Executive Board chairs and quota shares and with expanding and altering the Fund’s surveillance role, but not enough attention has been paid to whether organizational change at the staff level is also needed. IMF staff have intellectual dominance and discretion in the design of loan conditionality, writing of surveillance reports, and provision of technical and policy advice. There are also clear internal and external criticisms of how the Fund’s organizational culture—that is perceived to be hierarchical, technical/economistic, bureaucratic, and homogeneous/conforming—negatively affects the Fund’s policy output and relationship with borrowing members. This article suggests altering ’how things are done’ at the IMF by making changes to recruitment and organizational structure.

从组织行为模式看印尼大规模社交限制政策中的中央与地方关系

面对新冠肺炎疫情,印尼政府推出了大规模社交限制政策,其显著特点是中央和地方政府共同参与防疫.印尼地方政府在这项政策的出台与实施阶段扮演着怎样的角色?中央政府与地方政府间存在怎样的联动关系?这些都可以运用艾利森提出的政府决策组织行为模式进行分析.在大规模社交限制政策的出台与实施过程中,印尼中央政府各部门、中央政府与地方政府组织的行动均相互关联,各部门间存在显著的联动关系.这种联动关系的存在以及印尼的地方自治制度使地方政府可以通过变通执行、制定特殊政策、进行反馈等方式影响中央政府的政策内容及最终实施效果.随着地方自治制度下地方政府职能的加强,作为中央政府的基层组织,地方政府不再只是机械地执行中央政府政策的工具,而是所在地区社会服务的主要提供者.
