What do forensic analysts consider relevant to their decision making?

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making.     

步巡盘查战术演练中常见问题及其对策

近年来我国各地暴力袭警案件时有发生,综合分析这些已发生的暴力袭警案件,多数因公安民警在执行清查、盘查、检查和缉捕等警务活动中防范、控制不当而造成的。因此,在平时对公安民警进行的盘查战术演练中,应进一步增强基层民警临战意识,提高民警安全防范能力,坚决贯彻依法、合理、有效使用武器的指导思想,尽快加强和提高基层民警警务战术的实战能力,避免不必要的伤亡事故。

抗O型口蹄疫病毒单克隆抗体的制备及其生物学特性分析

用灭活O型口蹄疫病毒为抗原免疫BALB/c小鼠4次后,取致敏的脾B淋巴细胞和SP2/0小鼠骨髓瘤细胞进行融合,在HAT选择培养基中培养2周,经间接ELISA法筛选,最终获得了3株抗O型FMDV的阳性杂交瘤细胞株,命名为2F1、2G7和6H4。血清学试验证明该McAbs能与FMDV抗原结合,具有高度特异性。     

鸡IFN-γ重组鸡痘病毒对鸡传染性腔上囊炎MB43弱毒疫苗免疫鸡免疫应答的影响

将重组鸡痘病毒(rFPV-IFN-γ)与IBD MB43弱毒疫苗联合接种SPF鸡,研究重组鸡IFN-γ对IBD疫苗免疫效果的影响.结果显示,rFPV-IFN-γ和MB43弱毒疫苗联合免疫组(MB43+rFPV-IFN-γ)及rIFN-γ和MB43弱毒疫苗联合免疫组(MB43+rIFN-γ)在免疫后第2周即可检出ELISA抗体,比MB43疫苗单独免疫组早1周.用IBDV Gx株攻击后,MB43+rFPV-IFN-γ组和MB43+rIFN-γ组免疫鸡的脾只有个别淋巴细胞核浓缩、核崩解,少数滤泡萎缩变性坏死;胸腺损伤程度轻于MB43疫苗单独免疫组和非免疫对照组.免疫后1周,3个免疫组外周血CD8+T淋巴细胞含量均显著高于非免疫对照组,CD4+T淋巴细胞含量变化不明显;攻毒后第2周,3个疫苗免疫组CD4+、CD8+T淋巴细胞含量均显著升高,各组之间CD4+、CD8+T淋巴细胞含量无明显差异.证实,rFPV-IFN-γ和rIFN-γ可加强疫苗的细胞免疫和体液免疫应答.     

A NEW LOOK AT AN OLD ISSUE:

In 1997, the Office of Child Support Enforcement initiated the State Child Access and Visitation (AV) Grant Program, which involves annual awards of $10 million to states to promote the development of programs to alleviate access problems. Telephone interviews with 970 parents who used mediation, parent education, and supervised visitation programs funded by AV grants in nine states revealed that the programs are reaching diverse groups of parents including many low-income, non-White, and unmarried parents who receive no other type of access assistance. The programs also appear to be achieving the major objectives posited for them by the federal government. One-third to one-half of noncustodial parents in every program type reported that parent–child contact increased following program participation, with supervised visitation users who typically had the lowest levels of parent–child contact reporting a significant increase in the number of days of contact. A review of child support records for 173 program users in three states revealed that child support payments increased among participants following program participation, especially for never-married parents who paid a significantly higher proportion of what they owed. These findings are similar to results reported in a five-state study of mediation programs funded by AV grants that was conducted by the Office of the Inspector General. However, both studies have some serious limitations, including low response rates and the absence of a nontreatment comparison group.     

口蹄疫病毒3D基因的真核表达及其表达产物的功能分析

利用RT-PCR技术扩增口蹄疫病毒(FMDV)编码RNA依赖的RNA聚合酶的3D基因,经测序确认后将其克隆到真核表达质粒载体pcDNA3.1( )中,重组质粒pcDNA3.1( )-3D经HindⅢ、XbaⅠ双酶切后转染至BHK-21细胞,用纯化的目的蛋白进行Western-blotting鉴定,并预测该3D基因表达产物的三级结构。结果显示,获得分子质量约55 ku的单一3D基因表达产物,其三级结构较为保守。利用RNA细胞内复制体系和荧光定量RT-PCR技术,证明3D基因表达产物在细胞内可促进口蹄疫病毒基因组的复制。     

囊素对猪口蹄疫灭活疫苗的免疫增强作用

用提取的天然囊素(10μg/mL)和O型口蹄疫灭活疫苗协同免疫45日龄仔猪,研究了其对O型口蹄疫灭活疫苗免疫效果及仔猪增重的影响。将32头健康45日龄仔猪随机分为4组,0.5 mL疫苗 囊素免疫2次(Ⅰ)组1、.0 mL疫苗 囊素免疫2次(Ⅱ)组1、.0 mL疫苗 囊素免疫1次(Ⅲ)组和1.0 mL疫苗免疫2次(Ⅳ)组(疫苗对照组),用液相阻断酶联免疫吸附试验(LB-ELISA)检测各组猪免疫前及一免后第14、28、42、60、74、881、02 d的口蹄疫血清抗体效价并称重。结果,Ⅱ组抗体水平显著高于Ⅳ组(P<0.01),Ⅰ组、Ⅲ组和Ⅳ组间差异不显著(P>0.05);一免后第60~110 d仔猪平均日增重囊素组明显高于对照组(P<0.05)。结果表明,囊素可以提高口蹄疫灭活疫苗的免疫原性,提高猪增重,促进生长发育。
