职工董事职工监事制度立法现状及前瞻

近年来,职工董事职工监事制度的立法获得了快速发展,各地的地方性法规不断出台,使职工董事职工监事制度在立法体系、内容、程序等方面取得了一定的突破和进展。但是,综观当前的立法状况,仍然存在着许多不足,需要对职工董事职工监事制度立法中有关职工董事职工监事的人数比例、任职资格、薪酬、法律责任等不断进行完善,提高职工董事职工监事制度的立法层次,从而使其作用得到更充分的发挥。     

Stature estimation using foot dimensions via 3D scanning in Taiwanese male adults

In forensic identification, the use of foot dimensions to predict stature is a requisite. For Taiwanese male stature prediction, available information about stature estimation using foot dimensions is still lacking. Therefore, the primary purpose of this study was to establish Taiwanese adult male stature prediction models for various foot dimensions. A total of 2,072 male 3D foot models were collected and the subjects' ages ranged from 18 to 59 years old. Thirteen foot dimensions for each foot were utilized in this study. Bilateral differences were tested using paired t-tests. Stature predictions based on different foot dimensions were conducted using simple linear and stepwise regression methods. The results showed significant bilateral differences in the majority of the selected foot dimensions (p < 0.001). Foot length had the highest positive correlation with stature in the right and left foot. Using length-related dimensions generated better prediction accuracy (0.356 < R² < 0.533, 4.193 < SEE < 4.928), whereas the worst accuracy was observed with angle-related dimensions (0.001 < R² < 0.023; 6.072 < SEE < 6.137) when employing a single foot dimension to estimate Taiwanese male stature. Stepwise regression analysis results indicated that the coefficient of determination was improved to 0.590 and 0.593 by applying five and six foot parameters to predict stature, respectively. The findings of the present study suggest that these stature estimation equations can be applied to predict Taiwanese male stature in the forensic science field.     

大数据时代下的主动型侦查模式研究

侦查模式是侦查的最一般路由,侦查人员借助其对案件侦查形成基本的工作思路.当前犯罪出现了动态化、智能化、组织化的异化现象,处于基础性地位的反应型侦查模式在应对犯罪异化时遇到了困难.本文研究反应型侦查向主动型侦查转型的相关问题,借助了大数据对于行为、事件的预测功能扩展了原有的主动型侦查模式适用的外延范围并厘清了其在适用时所要解决的与反应型侦查所不同的法律问题.     

From polls to votes to seats: Forecasting the 2015 British general election

This paper develops a three-stage method to forecast parliamentary election results from vote preferences in British opinion polls: (1) adjusting and aggregating vote-intentions from different polling organizations; (2) forecasting how public support for parties will change in the period before election day; and (3) translating, through simulations, the forecast of election day vote shares into seat totals while incorporating constituency-level information, including local vote-intention polls. Overall, this approach seeks to combine relevant national, regional and local information, and uncertainty about that information, to better reflect the fragmentation and diversity of political contexts found in the new era of five/six-party British politics.     

Vertical Lip Position and Thickness in Facial Reconstruction: A Validation of Commonly Used Methods for Predicting the Position and Size of Lips

This study examined several methods used to estimate oral fissure position, lip margin position, and lip thickness recommended by Angel, George, Lebedinskaya, Taylor, Wilkinson et al., Balueva and Veselovskaya. A sample of 86 lateral head cephalograms of adult subjects from central Europe were measured and the actual and predicted dimensions were compared. The best estimation for oral fissure position was “opposite the lower ¾ mark of maxillary incisors” (error of 1.3 mm). Upper lip margin was predicted best by “upper ¼ mark of maxillary incisors” (error of 1.7 mm), and lower lip margin by “cementum‐enamel junction of mandibular incisors” (error of 2.3 mm). The regression equations of Wilkinson et al. displayed least error (1.3 mm and 1.8 mm, respectively) for upper and lower lip thickness, and method of George (error of 3.4 mm) for total lip thickness.     

牛趋化因子受体4基因的克隆表达及序列分析

采用RT-PCR技术,从被刺激诱导的牛外周血单个核细胞(PBMC)中克隆了牛趋化因子受体4(CXCR4)全长基因,并将CXCR4基因和CXCR4基因N端1～126 bp(CXCR4~(42aa))片段分别亚克隆到原核表达载体pGEX-4T-1中,命名为pGEX-4T-1-CXCR4、pGEX-4T-1-CXCR4~(42aa).获得重组菌株后,采用不同的IPTG浓度、不同诱导时间、不同温度和不同培养基等组合诱导表达这两种重组菌,其中pGEX-4T-1-CX-CR4~(42aa)重组菌获得了表达,并在37℃、IPTG浓度为0.8 mmol/L、诱导6 h时表达量最大,约占菌体总蛋白的45%,目的蛋白主要以包涵体的形式存在;而pGEX-4T-1-CXCR4重组菌未表达出目的蛋白.

Application of MALDI‐TOF MS for Estimating the Postmortem Interval in Rat Muscle Samples

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.     

Skeletal height reconstruction from measurements of the skull in indigenous South Africans

Stature reconstruction is important as it provides a forensic anthropological estimate of the height of a person in the living state; playing a vital role in the identification of individuals from their skeletal remains. Regression formulae for stature estimation have been generated for indigenous South Africans based on measurements of long bones of upper and lower extremities and the calcaneus. Since these bones are not always available for forensic analysis, it became necessary to use other bones such as the skull for stature estimation. The aim of the present study was to investigate the usefulness of certain measurements of the skull of indigenous South Africans in the estimation of adult stature. Ninety-nine complete skeletons obtained from the Raymond A. Dart Collection, School of Anatomical Sciences of the University of the Witwatersrand, were used. Total skeletal height (TSH) was calculated for each skeleton using the Fully's (anatomical) method. Furthermore, six variables were measured on each skull. TSH was regressed onto these cranial measurements in order to obtain regression formulae. The correlation coefficients obtained ranged between 0.40 and 0.54. The range of the standard errors of estimate from the current study (4.37 and 6.24) is high in comparison to that obtained for stature estimation based on intact long bones and the calcaneus. Therefore, the equations presented in this study should be used with caution in forensic cases when only the skull is available for human identification.
