公安院校在职教育与学历教育双向互动探析

当前,公安院校实行普通学历教育与在职教育并重发展的模式,以学历教育为依托提高在职民警培训的层次和质量,以在职民警培训为导向促进学历教育进一步贴近实战,在双向互动、资源共享中实现双赢,为公安院校办学重心逐步向在职培训转移奠定基础。本文仅从在职教育与学历教育双向互动的现实意义和运作方式两个方面做些探讨。     

Blind validation of postmortem interval estimates using developmental rates of blow flies

This study evaluated the use of different degree day (DD) models, developmental thresholds and developmental data sources for estimating postmortem interval (PMI) based on developmental rates of blow flies (Diptera: Calliphoridae). Blow fly evidence was collected from three mock crime scenes and sent for blind analysis of PMI. PMI estimates were calculated using averaging, single sine, double sine, single triangle, and double triangle models of DD calculation with minimum developmental thresholds of 0, 6 and 10 °C and Anderson's, Byrd and Allen's, Greenberg's, Nishida's and Kamal's developmental data sets. These estimates were compared with the actual PMI to determine which combination of DD model, developmental threshold and developmental data provided the most accurate estimate. For all three cases, at least one method gave a PMI estimation that was within 1 day of the actual date of death. There was no variability between PMI estimated using the five models of DD calculation. Overall, as lower developmental threshold increased, the PMI interval estimates increased. Depending on the developmental data set used, increasing the lower developmental threshold caused some overestimations of the date of oviposition, with estimates given that were prior to the actual death. Future PMI estimates should include error ranges, so that overestimation of PMI is avoided.     

回到马克思：解开剥削问题的死结

马克思将剩余价值分解为初始剩余价值、绝对剩余价值和相对剩余价值三个组成部分,其中相对剩余价值是资本通过提高劳动生产力得到的,不是靠剥削工人的劳动得来的。因此,资本家占有相对剩余价值不是剥削,不能滥用剩余价值率来衡量剥削程度。但在现实中,剩余价值三个组成部分之间的界限是模糊的,劳资双方为争取各自的利益展开博弈。政府的作为在于用法令缩短工作日,限制剥削,促进全社会劳动生产力的提高。

200例活体损伤程度鉴定分析

本文对200例活体损伤程度的鉴定进行了统计和分析(1983～1986)。结果表明:重伤占42.5%,轻伤占57.5%。男性占83.5%,女性16.5%。年龄以青少年组为多。致伤物以拳脚占首位。损伤部位以颅脑损伤最多。并发症的出现率为20.5%;后遗症的出现率为38%。本文对原发性损伤、并发症、后遗症在活体损伤程度鉴定中的重要意义亦进行了讨论。     

The formation of early stage adipocere in submerged remains: a preliminary experimental study

In some circumstances, the presence of adipocere may retard decomposition and complicate postmortem interval estimation. This article explores the correlation between Accumulated Degree Days (ADD) and early stage formation of adipocere. Sixty wild rabbit (Oryctolagus cuniculus) carcasses were used in this experiment; a control group (N = 30) deposited directly on the ground surface and an experimental group (N = 30) completely submersed in water in individual buckets. Data (water and inner body temperature, pH, and total body score) were collected every 100 ADD. Results indicated that early stage adipocere is correlated to ADD and that its formation on submersed remains is more likely to occur after 630 ADD. Skin sloughing promoted the formation of adipocere. No adipocere was formed on any of the control group rabbits. This study also highlights the fact that multiple factors influence adipocere formation and it is suggested that further research needs to be conducted into this area.

目的　探讨火器损伤的致伤特点及活体损伤程度鉴定的有关问题。方法　 6 3例火器损伤主要按火器枪弹种类及数量分为四组 ,Ⅰ组 :霰弹损伤 ;Ⅱ组 :气枪损伤 ;Ⅲ组 :军用枪损伤 ;Ⅳ组 :射钉枪与爆炸损伤 ,对其进行前瞻与回顾性分析总结。结果　Ⅰ组损伤多见于斗殴 ,损伤部位以四肢部多见 ,异物存留、损伤程度明显高于其它各组 ;Ⅱ组损伤多见意外 ,不易造成异物存留 ;损伤程度轻于其它各组 ;Ⅲ组损伤多见抢劫与杀人 ,损伤部位多见头部 ;Ⅳ组损伤较少见仅占 7 92 %,不是本文讨论的重点。四组损伤合并脏器、神经血管损伤及骨折 33例 ,占 5 2 38%,构成重伤、轻伤 5 0例 ,占 79 37%。结论　火器损伤程度较重 ,致伤机理有其自身特点 ,现行损伤程度鉴定标准对其体现不够 ,值得法医同仁加以重视。     

The suitability of visual taphonomic methods for digital photographs: An experimental approach with pig carcasses in a tropical climate

In the context of increased scrutiny of the methods in forensic sciences, it is essential to ensure that the approaches used in forensic taphonomy to measure decomposition and estimate the postmortem interval are underpinned by robust evidence-based data. Digital photographs are an important source of documentation in forensic taphonomic investigations but the suitability of the current approaches for photographs, rather than real-time remains, is poorly studied which can undermine accurate forensic conclusions. The present study aimed to investigate the suitability of 2D colour digital photographs for evaluating decomposition of exposed human analogues (Sus scrofa domesticus) in a tropical savanna environment (Hawaii), using two published scoring methods; Megyesi et al., 2005 and Keough et al., 2017. It was found that there were significant differences between the real-time and photograph decomposition scores when the Megyesi et al. method was used. However, the Keough et al. method applied to photographs reflected real-time decomposition more closely and thus appears more suitable to evaluate pig decomposition from 2D photographs. The findings indicate that the type of scoring method used has a significant impact on the ability to accurately evaluate the decomposition of exposed pig carcasses from photographs. It was further identified that photographic taphonomic analysis can reach high inter-observer reproducibility. These novel findings are of significant importance for the forensic sciences as they highlight the potential for high quality photograph coverage to provide useful complementary information for the forensic taphonomic investigation. New recommendations to develop robust transparent approaches adapted to photographs in forensic taphonomy are suggested based on these findings.
