射击残留物与射击距离的判断

当前我国的持枪犯罪率越来越高,这类犯罪的犯罪性质恶劣,社会危害大,严重影响着社会的安定与稳定,是各级公安机关重点打击的犯罪行为。因此,关于弹道检测等相关原理与应用的研究越来越受学者的关注。射击距离的判断对于分析案件的性质,作案过程的推断、确认射击位置和方式具有重要作用,也只有先确定了射击的距离才有可能进行下一步的数据计算。因此,如何推断射击距离,成为检验鉴定枪击案件的首要问题。因此,本文位从检测射击残留物对射击距离的判断展开论述。     

头发对射击残留物附着的影响

利用射击残留物的存在和分布形态判断枪口与射入口的距离是现场分析的关键之一。然而我们在工作中发现,在对头部射击的案件中,弹孔周围的头发有可能对射击残留物起到屏蔽作用,尤其在贴近距离[1](2cm~5cm左右)射击的时候,绝大部分射击残留物会附着在头发而不是头皮上,本文将以实验和真实案例为基础详细说明近距离射击时头发对射击残留物附着的影响。     

发射光谱与计算机联机判断手枪近距离射击距离的研究

本文采用发射光谱与计算机联机检验手枪射击残留物中的特征指示元素,利用特征指示元素黑度差与其射击距离的工作曲线判断手枪近距离射击时的射击距离。在大量实验的基础上摸索出了较佳的实验条件,并通过微机建立了数据处理系统,其方法简单,结果准确。     

92式手枪射击距离与射击残留物分布密度相关性的研究

目的研究92式手枪射击距离与射击残留物分布密度的相关性,为射击距离的推断提供依据。方法选择92式手枪,在带皮的猪肉上覆盖白色棉布,设计了0m,0．1m,0．2m,0．5m,1．0m,1．5m,3．0m,5．0m,10m,15．0m,20．0m,25．0m共12个距离进行射击,提取白棉布上的弹孔圆周和距弹孔2cm的圆周上的射击残留物,利用扫描电镜／能谱仪对不同射击距离遗留在白棉布上的射击残留物进行检验。结果白棉布上射击残留物分布密度与射击距离呈负相关的关系。结论根据棉布上射击残留物的分布密度,能够推断射击距离,对涉枪案件中射击距离的判断有一定的参考价值。     

Sequence polymorphisms at the DXS6789, DXS8377 and DXS101 loci in three Asian populations

Sequence analyses of X-chromosomal short tandem repeats, DXS6789, DXS8377 and DXS101 were performed for representatives of 3 Asian populations: 130 Japanese, 61 Bangladeshi and 89 Indonesian males. At DXS6789, the sequence polymorphism was found in 7 alleles in the Japanese, 3 in the Bangladeshis and 3 in the Indonesians. At DXS8377, the sequence polymorphism was found in 13 alleles in the Japanese, 9 in the Bangladeshis and in all alleles identified in the Indonesians. At DXS101, the sequence polymorphism was found in 7 alleles in the Japanese, 9 in the Bangladeshis and 8 in the Indonesians. Because sequence polymorphisms were found in most of the alleles at the DXS6789, DXS8377 and DXS101 loci, it was concluded that sequencing was essential for identifying the alleles at these loci in all 3 Asian populations.     

对物诉讼与我国的船舶扣押法律制度

对物诉讼源于罗马法,却只在英国得到延续,并在其海事诉讼中得到巨大发展.随着英国殖民者将对物诉讼制度带到其殖民属地,移植法律与本地法律互相作用,逐渐发展出英美法系各国目前各具特色的扣船制度,其中最有代表性的莫过于英美两国的对物诉讼制度.我国的扣船制度既坚持了对人诉讼的传统,又大胆吸收了对物诉讼制度的合理内涵,反映了国际船舶扣押立法中对人诉讼与对物诉讼相互融合的良性发展态势.     

Gender differences in the dispersal of children in northern Sweden and the northern USA in 1850

In the course of time families disperse and kin relationships change. In this study gender differences in spatial dispersion of adult children from their fathers were investigated in two areas of the world in 1850: the Skellefteå region in northern Sweden and the northern part of the USA, both largely rural populations. The results from the Skellefteå region where data on both genders were available were used to estimate gender differences among a native born population in the northern USA where women were often not followed in the sources after marriage. Most adult children resided in the same place as their fathers, but the distances separating relatives were greater in the USA. However, the proportion of adult sons living in the same locality as their fathers was the same in both. More daughters than sons were located elsewhere in Skellefteå and probably also in the USA. Although sisters in Skellefteå joined each other in places separate from their parents, men lived in patrilineal clusters to a greater extent than women due, in part, to patrilineal inheritance and virilocal marriages. Various reasons for these patterns are discussed and their implications for kin networks discussed.

National Consensus or Social Anomaly?

The dynamics of mass consciousness in Russia, formed in the wake of the 2014 events in Ukraine and Crimea, testify to the consolidation and radicalization of the popular majority. The national consensus has shaped a high level of public optimism even in the face of deteriorating socioeconomic conditions. However, this process brings to the fore archetypal traits that in many ways run contrary to the modern desire for mass consumption, which in many ways is also contrary to social mobilization. This contradiction will affect the political process, if not in the short- then in the long term, and will significantly affect the sociopolitical situation, making it less stable than in the first decade of the present century.     

Petechial Hemorrhages and Ethanol in Deaths from Intoxication

Petechiae in conjunctivae and in the palpebrae/skin of the eyelids are of particular interest for the forensic pathologist, because of their association with pressure on the neck. They have been described in the eyelids of intoxicated persons both in case reports and in text books of forensic pathology. We studied 590 deaths caused by intoxication, and 75 had petechiae either in the conjunctivae, the eyelids, or in both locations. We examined the influence of drugs and ethanol on the location of the petechial hemorrhages in these deaths. Deaths with ethanol in blood and in urine/vitreous humor more often had petechiae in both locations than those without. This association was statistically significant, independent of body position and livor mortis. No association between the location of petechiae, medicinal drugs, or narcotics was found. These results suggest that ethanol may contribute to the development of petechial hemorrhages in deaths from intoxication.     

Public confidence in the police: tests of instrumental and expressive models in a developing country city

This paper examines the effect of instrumental and expressive concerns on public confidence in the police in three different residential areas in Sekondi-Takoradi, Ghana’s third largest city. The study was important because of the knowledge vacuum that existed in regard to the empirical validity of the instrumental and expressive theoretical framework within the Ghanaian context. Data for the study was drawn from a baseline survey conducted in three residential areas in the Sekondi-Takoradi metropolis. The findings revealed that instrumental factors played a more significant role in influencing confidence in the police in the Sekondi-Takoradi metropolis compared to expressive factors. More importantly, instrumental factors played a more significant role in influencing confidence in the police at Anaji compared to the other two residential areas used in the study. The paper recommends that there should be more investment in police infrastructure and services to enhance police effectiveness and efficiency. Additionally, the authors also suggest that interventions aimed at improving security at the community level should be guided by periodic safety audits since this will provide a better understanding of the criminogenic problems within these residential settlements.     

氯胺酮滥用的毛发分析研究

目的建立毛发中氯胺酮及其代谢物的分析方法并探索氯胺酮进入毛发的机理。方法通过建立豚鼠连续给药(不同剂量)实验模型获取阳性头发和采集氯胺酮滥用者头发,经处理后用GC/MSscan和SIM法分析,以鉴别、确认毛发中氯胺酮及其代谢物。结果豚鼠毛发中氯胺酮的质量分数与给药剂量存在明显的正相关性。毛发中氯胺酮质量分数依白色、棕色、黑色毛发顺序随毛发中黑色素的质量分数增加而增加。豚鼠毛发中氯胺酮与代谢物NK质量分数之比为2.33～12.94,仅在高剂量组的豚鼠毛发中才检测到DHNK,其质量分数与NK接近。15名氯胺酮滥用者黑色头发中均检出原体和代谢物NK,但DHNK少见。豚鼠毛发中代谢物相对质量分数明显高于人。结论本实验结果很好地反映了药物进入毛发代谢过程与药物和黑色素亲和力以及药物的亲脂性密切相关这一规律,但人和动物在药物代谢及进入毛发的难易程度上存在差异。本方法可以用于法庭毒物分析领域头发中氯胺酮的检测。     

永佃权的历史考察及其当代价值

本文对中外永佃权的历史做了粗略的梳理 ,以期辨正学界对永佃权某些方面的误解。以此为据 ,进而阐明永佃权的当代价值。在考察中国和国外法律史的过程中 ,采用可靠的史料是重要的 ,而使用该国文化中特定的语言系统又是必须的。中国古代存在永佃制 ,但绝没有永佃权 ;中国的永佃制萌芽于隋唐而非秦汉或北宋 (英宗 ) ;永佃权虽然生成于私有制的土壤 ,但对我国物权法中的农地立法 ,仍有借鉴的价值。     

Illegal entrepreneurs: a comparative study of the liquor trade in Stockholm and New Orleans 1920–1940

The 1920s were a golden period for smuggling in Nordic waters, as systems of prohibition were established in Finland, Norway and Iceland, while in Sweden an intricate system of rationing was implemented in 1917. A comparative study of the illegal liquor trade in Stockholm and New Orleans shows that the actual methods of smuggling were similar in the two cities. Mother ships brought the cargo to a point outside territorial waters, where it was shifted to smaller boats. These brought the liquor in through the archipelago of Stockholm or the bayous of the Mississippi delta. The relative lack of corruption in Sweden did not limit the extent of the black market. According to contemporary estimates, the amount of smuggled liquor was about the same in the two cities. The kind of alcohol that was brought in was different, however, and the value of the trade higher in New Orleans. Also, the organization of the trade differed, in terms of ownership and distribution. In neither city did the illegal entrepreneurs appear to be very violent. The fact that the rate of violence was much higher in New Orleans, than in Stockholm, did not seem to affect their business methods.
