人耳自动识别技术探讨

人耳识别是一种新的生物识别技术。一套完整的人耳自动识别系统一般应该包括以下几个环节:人耳图像采集、图像预处理、人耳图像的边缘检测与分割、特征提取、样本训练和模板匹配。人耳识别方法主要有主元分析法、神经网络法、力场转换方法、基于3D耳朵检测和识别方法。     

DNA指纹图在法医学鉴定中应用的研究(Ⅰ)

应用 MYO DNA 探针对中国人进行了 DNA 遗传指纹图检验。从两个家系16人及100个无关个体中取肘静脉血提取 DNA,用限制性内切酶 HinfⅠ或 HaeⅢ水解,1%琼脂糖凝胶电泳分离,经 Southern印迹转移,MYO DNA 探针杂交,获得了清晰可辨的 DNA 指纹图谱。结果每个个体在3.0Kb 以上均能检出10条以上杂交区带,个体间的相关概率<4×10~(-9),由杂交区带构成的图谱是个体特异的,杂交区带遵循孟德尔的显性遗传方式由亲代向子代遗传;具有 DNA Fingerprints 的特点。对两起亲子鉴定的案例进行指纹图检验,孩子所存在的杂交区带,除来自母亲外,其余可在嫌疑父亲带中找到,肯定了孩子与嫌疑人的父子关系。MYO DNA 探针在亲子鉴定与个人识别的法医学鉴定中有着重要的实用价值。     

关于上颌牙弓性别差异的研究

利用自动显示游标卡尺测量200例（男、女各100例，年龄18～24岁）上颌石膏模型上牙弓宽、长及高等18个指标。经统计分析发现除切牙弓长、尖牙间距对应高及第二双尖牙间距对应高外，其余15项测量指标男性均大于女性（P＜0．05）。逐步判别分析仅用7个测量指标，判别率可达到75．50％。     

论我国刑法中公共安全的内涵及其认定标准

目前刑法学界关于公共安全的内涵界定的各种观点,都狭于我国刑法关于危害公共安全具体罪名的立法精神。我国刑法规定的公共安全的内涵应当是指"不特定或者多数人的生命、健康、财产安全,重大公私财产安全,重大生产安全,公共生活安宁以及重大公共利益的安全"。危害公共安全的认定标准是两个方面的有机结合:行为本身的高度危险性和行为危害结果"不特定"或者"多数"的客观可能性。这种判断标准是行为无价和结果无价的相互结合。     

侦查阶段告知义务体系的完善

侦查机关的告知义务对保障和实现犯罪嫌疑人的基本诉讼权利具有重要意义。而我国刑事诉讼法中对侦查机关的告知义务规定得过于简单,在具体运用时必然造成执法机关无法可依,犯罪嫌疑人的基本诉讼权利不能得到真正保障。构建我国侦查阶段告知义务体系,应当明确告知义务包含的主体、履行方式、范围、内容、时间及其附随义务等基本要素。并根据联合国关于告知义务的规定及域外其他国家与地区的先进做法,完善我国侦查机关的告知义务。     

120例闭合性颅脑损伤的临床诊断与法医鉴定的结论差异分析

有关闭合性颅脑损伤的临床诊断与法医鉴定的结论往往存在着差异,在脑震荡和脑损伤后综合症诊断上,这种差异尤为突出。差异的形成主要缘于临床诊断:临床医生过分依赖主诉;自信、草率、违反医理;对病人辅助检查不够;易受社会和人为因素干扰。     

放弃重复侵害行为相关问题分析

对于如何定义放弃重复侵害行为,国内外有不同的观点,但都有可商榷之处,需要重新进行认识。对于该行为的性质,应当认定为未实行终了的犯罪中止,而非实行终了的犯罪未遂,因此也应按犯罪中止的刑法规则进行处罚。将放弃重复侵害行为认定为犯罪中止有着积极的作用,可以有效预防行为人实施重复侵害,阻止犯罪结果的出现,也可以使可能犯罪的人更明确中止制度的意义,放弃可能实施的侵害,从而更有利于一般预防和特殊预防的实现。     

Culture Wars,Secular Realignment,and the Gender Gap in Party Identification

Changes in the U.S. partisan balance over the past decade are often attributed to the enhanced political salience of cultural issues. Yet as white men have continued to become more Republican in recent years, white women increasingly identify with the Democrats. To the extent that cultural issues are influencing this partisan change, men and women must be responding differently to this cultural agenda. Using a pooled ANES data set from 1988 through 2000, I explore the extent to which cultural values are responsible for this gender realignment. Findings suggest that salient cultural issues influence the partisan choices of both men and women, however in somewhat different ways. For women, the issues themselves—reproductive rights, female equality, and legal protection for homosexuals—have become increasingly important determinants of party identification. For men, the influence of cultural conflict on partisanship is argued to be equally pervasive, albeit less direct.     

Parental Socialization and Rational Party Identification

This article constructs a rational choice model of the intergenerational transmission of party identification. At a given time, identification with a party is the estimate of average future benefits from candidates of that party. Experienced voters constantly update this expectation using political events since the last realignment to predict the future in accordance with Bayes Rule. New voters, however, have no experience of their own. In Bayesian terms, they need prior beliefs. It turns out that under certain specified conditions, these young voters should rationally choose to employ parental experience to help orient themselves to politics. The resulting model predicts several well–known features of political socialization, including the strong correlation between parents' and children's partisanship, the greater partisan independence of young voters, and the tendency of partisan alignments to decay.
