社会工作专业学生认同感的培养初探

由于专业外在发展环境和内在教育状况的影响，社会工作专业的学生对所学专业认同感比较低。这种状况制约着教育目的的实现和学生学习质量的提高。为了培养学生的专业认同感，教师既要努力提高专业的社会认同度和职业化程度，又要提高教学质量，增进学生对专业的工具性价值的了解。     

基于车牌识别的交通流结构分析

交通流是交通需求在有限的时间与空间上集散现象。传统的交通流理论以流量、速度、密度这三个基本参数作为交通信息采集对象，存在信息种类少，分析手段单一等不足。以车牌号作为唯一标识，应用先进的电子信息技术采集动态的交通流信息，并结合静态的车辆档案数据，可以更全面、更精准、更深入地掌握交通流结构和规律，是对传统交通流采集方法的一次革命。     

分泌抗人精子单克隆抗体杂交瘤细胞株的建立及鉴定

建立两株分泌抗人精子单克隆抗体的杂交瘤细胞株G_8与E_(10),采用洗涤人精子免疫Balb/c小鼠,取免疫脾与Balb/c小鼠的Sp2/0骨髓瘤细胞融合,杂交瘤细胞诱生腹水的方法。Elisa,IIF或酶标抗体免疫组化法结果发现,G_8与E_(10)单抗与人精子(射出精子、睾丸、副睾管及输精管中的精子)及睾丸各级生殖细胞均发生反应;与人甲状腺上皮细胞、肾小管上皮细胞、胰腺导管上皮细胞以及胰岛均发生不同程度的交叉反应,与其他33种人体正常组织、9种人体液与分泌液、8种不同种族的动物精子均不发生交叉反应,说明在一般情况下这两种抗体可用于鉴定人类的精液斑以及精液与阴道分泌液的混合斑。两种单抗与人精子的顶体部、赤道部、后核帽、颈部及中段结合,证明精子特异性表面抗原分布于这几个区域。两种抗体均属IgG_1,G_8与E_(10)抗体的效价分别为1:512与1:1024。     

Identification of personal height from the somatometry of the hand in Punjabi males

The present study is based on a sample of 100 normal healthy Punjabi males from Patiala, Punjab, India. Each subject has been studied for three anthropometric measurements: stature, hand length and hand breadth. The data have been subjected to statistical computation for the statistical constants like mean values, standard deviation, standard error of mean, test of significance (test of normal deviates) and regressions. The data have been studied for somatometry pertaining to height, hand length and hand breadth. Bilateral symmetry in both the measurements, hand length and hand breadth, indicate insignificant variations. Regression equations have been computed and regression lines have been drawn for the estimation of stature from somatometry of hand.     

混合显现液对三种渗透性纸张上潜汗指印的显现

通过正交试验筛选出2%茚三酮与0.5%硝酸银/乙醇混合液分别对牛皮纸、硬纸板、A4复印纸三种客体表面上不同时期遗留的潜汗指印进行显现。结果表明该混合显现液均能显现渗透性和非渗透性客体上的新鲜指印,和不同时期的陈旧性潜汗指印。而且对陈旧性潜汗指印的显现效果与常见的显现方法的显现效果进行了对比,分析得出混合显现液在许多方面存在较多的优势。     

女性普通话塞音过渡音征个体特性初探

目的考察塞音过渡音征的个体特性及在说话人鉴定中的价值。方法选取9位女性发音人普通话中的6个塞音与元音/i、a、u/组成的单音节,提取每个音节F2、F3的起点值和目标值进行统计分析,并计算说话人的塞音音轨。结果 （1）过渡音征形态特征在不同说话人之间具有差异;（2）各音节的说话人区分率呈现较大区别,音节/tu/的说话人区分率较高而/khu/音节几乎不具备说话人区分能力;（3）与零声母音节相比,音节中3个元音的F2共振峰频率均值受到塞音的影响而提高,其中/i、a/F2提高的幅度要大于/u/;（4）不同说话人的音轨存在差异。结论在说话人鉴定中选取塞音音节进行比对时要注意不同音节的说话人区分率,尽量避免选取舌根塞音音节;塞音过渡音征的形态和音轨数据可以应用于说话人鉴定。     

The Analysis of a World War I U.S. Service Member's Dental Remains Recovered in France

In October 2009, the grave of an unknown World War I (WWI) U.S. service member was exhumed in Rembercourt‐Sur‐Mad Village, in the Lorraine Region of France. The skeletal remains and material evidence were accessioned into the Joint POW/MIA Accounting Command's (JPAC) Central Identification Laboratory (CIL). The personnel records for the associated casualty were requested, received, and reviewed. A dental profile was present among the service member's personal information. There were multiple points of concordance between the dental records of the associated casualty, and the recovered dental remains to include eight restored teeth, 15 unrestored teeth, and three antemortem missing teeth. Distinctive restorations which compared favorably included a porcelain crown and multiple gold foil fillings. All lines of evidence (historical, material evidence/personal effects, anthropological, and dental) and the circumstances of loss compared positively with the associated casualty. On April 1, 2010, the previously unaccounted‐for U.S. service member was positively identified and on June 23, 2010, was buried with full military honors at Arlington National Cemetery.     

EYEWITNESS RECALL AND PHOTO IDENTIFICATION: A FIELD EXPERIMENT

Some 590 men and women were tested in public places for interrogative recall and photo identification of a young woman to whom they had spoken for approximately 15 seconds, either 2 minutes earlier or 4 hours earlier. The target was seen originally either with or without a baseball cap and dark sunglasses. Witnesses were either prepared or not prepared at the time of the encounter for a subsequent memory test. Half of the witnesses were given imagery retrieval instructions or standard retrieval instructions prior to the two memory tests. A separate group of 379 introductory psychology students attempted to predict the performance of the eyewitnesses. Witness preparation was of more importance for recall of clothing characteristics than for physical characteristics. Witness preparation, target disguise, retention interval, gender of witnesses, and retrieval instructions had no significant main effects on identification. Forty-nine per cent of the witnesses given the target-present lineup correctly identified the target, and 62% correctly rejected the target-absent lineup. Student's beliefs in the accuracy of recall and identification were not consistent with eyewitnesses’ performance.     

从眼外伤损伤程度条款设计看新标准修订思路

损伤程度鉴定是法医临床学司法鉴定的主要内容。近年来,法医学司法鉴定工作人员不断呼吁对1990年与1996年发布实施的人体损伤程度鉴定相关标准进行修订。将于2014年1月1日施行的《人体损伤程度鉴定标准》,在条款内容和结构设计上发生了很大的变化,备受司法鉴定工作人员的广泛关注。眼外伤是比较常见的损伤类型,（《人体损伤程度鉴定标准》对眼外伤的条款规定较以往变化明显。本文从眼外伤的条款设计出发,通过横向和纵向比较,探讨和总结新标准的修订思路。     

腭缝的年龄变化

作者对231具中国汉族成年男性的干燥颅骨腭缝的年龄变化进行了分析研究。发现腭缝的愈合随着年龄的增加而有规律地增加。并且在45岁以前更加明显。通过对汉族成年男性腭缝愈合与年龄变化关系的研究,从中发现了腭缝愈合年龄变化的初步规律,为骨骼年龄变化的判断提出了一个新的方法。
