房室结纤维和脂肪增多与房室结动脉狭窄的关系

目的探讨房室结纤维、脂肪含量与房室结动脉狭窄之间的关系,分析房室结内病理性纤维化和病理性脂肪浸润的原因。方法选取119例心源性猝死案例,用Image-pro plus图像分析软件检测组织切片,计算房室结面积,房室结动脉内径、房室结动脉管腔面积(lumen area,LA)、外周横截面积(perimeterarea,PA),纤维组织面积和脂肪组织面积。将所有案例分为动脉狭窄组和正常对照组组,观察房室结动脉PA/LA值及房室结纤维及脂肪含量的改变。结果狭窄组房室结动脉PA/LA值在21～40岁最大,40岁以下两组房室结脂肪含量和总间质含量差异有统计学意义。结论房室结动脉狭窄与房室结间质含量增多有一定关系。     

论环境政策与环境法律的环境保护合力作用

我国的环境保护工作起步于环境政策,在建设法治国家进程中环境政策与环境法律的并存是客观实际的需要。环境政策和环境法律是我国保护环境的两种有效手段,二者有着共同的利益基础,二者并不矛盾,应当协调配合,共同发挥环境保护的合力作用。本文分析了环境政策与环境法律协调发展的理论基础,提出在现阶段环境政策和环境法律应当并存,进而提出正确处理环境政策与环境法律的协调配合关系。     

西方司法理念与司法制度

在以孟德斯鸠、贝卡利亚为代表的人道主义司法理念的影响下,近代以来西方国家的司法制度进行了人道化改革,逐步确立了罪刑法定、无罪推定和审判公开等原则;自古希腊以来的司法平衡智慧对近代以来的西方司法制度也颇有影响,如西方各国法律中确立的司法原则——当事人对等原则和辩诉交易制度等等,就体现了司法平衡的理念,而所谓司法平衡就是指通过司法途径实现利益上的平衡;自古希腊以来的司法正义理念对西方司法制度也产生了持久的影响,这一理念强调通过司法途径来实现形式正义(程序正义)与实质正义(实体正义),英国的衡平法以其对实质正义的追求而弥补了侧重于追求形式正义的普通法的不足,从而在英国法律体系中达到了实质正义与形式正义之间的平衡。     

创新理念思路举措 努力引领基层法律援助事业科学发展

法律援助作为中国特色社会主义司法制度的重要组成部分,在维护困难群众合法权益、保障公平正义、促进和谐稳定中发挥着重要的职责和作用。在目前我国改革发展正处于关键时期的新形势下,在深入推进社会矛盾化解、社会管理创新、公正廉洁执法三项重点任务面前,如何以科学发展观为指导,着力创新理念、思路、举措,努力引领和推进法律援助事业又好又快发展,是当前各级司法行政机关和法律援助机构面临的一项重点课题,需要我们进行理性思考、深度探索和大胆实践。     

A Novel Pixel‐Based Method to Estimate the Instantaneous Velocity of a Vehicle from CCTV Images

In traffic forensic identifications, it was usually unfavorable that estimated velocities of questioned vehicles derived from frame‐based methods eventually turned out to be close to but a bit less than speed limits. In this paper, a novel pixel‐based method was presented to estimate vehicles’ relatively instantaneous velocities. First, two adjacent pixels’ actual distance was acquired from the closed‐circuit television (CCTV) images. Then, the instantaneous average velocity within this one frame interval time (FIT) was calculated out. The frame‐based method and its evaluating result were also introduced in this paper. The results showed that the velocity estimated by this new pixel‐based method was higher than which derived from the frame‐based method. Employing this presented novel method in these cases, it could be more accurately identified whether or not the vehicles had exceeded the speed limits, and then the responsibilities could be consequently assigned impartially.     

浅谈文化差异与英语学习

语言是文化的载体 ,具有鲜明的民族性。不同的文化之间自然会呈现不同的文化形态。这种文化形态差异反映到语言层面上 ,则表现为语言差异。尤其是词语文化和话语文化 ,英语和汉语在解释具体内容时具有显著的差异。     

刑事和解的经验与问题——对北京市朝阳区刑事和解现状的调查

北京市朝阳区人民检察院在全国率先开展了刑事和解的实践.五年来,该院在限定刑事和解适用范围和条件、规范适用程序、尊重双方意愿、健全监督机制等方面积累了不少成功的经验,但同时还面临着检察官角色难定位、被害人承诺效力不明确、预防犯罪效果不确定、适用标准难统一、社会公平受质疑、考评机制待完善等亟待解决的问题.我们应当积极探索,稳步推进,不断培育和完善刑事和解这一崭新的刑事司法模式.     

农民合作经济组织发展进程中地方政府行为

在我国农民合作经济组织的发展进程中,政府承担着重要职能。但是,由于对合作经济组织认识上的误区,导致政府特别是地方政府在扶持农民合作经济组织问题上,要么”过度热情”;要么”过度冷漠”,制约了农民合作经济组织的健康发展。为此,政府应当优化其行为,加大对农民合作经济组织的扶持、加快合作经济体制的创新、加强对农民的教育和对合作经济组织的指导、规范合作经济组织的形式。     

Intra- and inter-speaker variations of formant pattern for lateral syllables in Standard Chinese

Speech variation of speakers is a crucial issue for speaker recognition and identification, especially for forensic practice. Greater intra-speaker variation is one main reason for incorrect speaker identification in real forensic situations. Understanding the stability of acoustic parameters and their variation in speech is therefore significant for the evaluation of effective parameters for speaker identification. In this paper, all vowels in Standard Chinese including five monophthongs, eight diphthongs and four triphthongs were combined with lateral /l/. Finally, 15 lateral syllables with different tones for 10 speakers were selected and acoustically analyzed. Central frequencies of the first four formants for each syllable were measured for quantitative comparison of intra- and inter-speaker variation in order to provide a general idea of speaker variation in Standard Chinese, and finally serving for forensic application. Results show that the overall intra-speaker variation is less than the inter-speaker variation in great extent under laboratory condition though occasionally they are contrary. This supports the basis for forensic speaker identification, that is, intra-speaker variation should be less than inter-speaker variation in many acoustic features, and further validates the probability and reliability of forensic speaker identification.
