The aim of this work was to study taphonomic marks that cadaveric coleopteran can produce under controlled conditions. To evaluate this, pig trotters were initially exposed to adults of Dermestes maculatus De Geer at 21 ± 5°C and a 12:12‐h day/night cycle. Observations were made and photographs taken every 4–5 days for 9 months. When feeding and reproducing, D. maculatus produced, in both adult and larvae stages, different types of marks such as holes, striations, scratches, and pits in several kinds of tissue such as integumental, connective, and muscular, in both their fresh and dried stages. Bite marks were also evident. The results in this study provide not only taphonomic but also biological and forensic information. This is the first time that this kind of experiment has been performed.  相似文献

The social problems of drug abuse are a matter of increasing global problem. Nowadays, international agencies need fresh methods to monitor trends of the use of illicit drugs. In this sense, small amounts of drugs are transferred to banknotes and they could be detected and quantified. An analytical procedure based upon extraction with organic solvent, liquid chromatography separation, and mass spectrometric detection allowed the identification of 21 drugs and metabolites in 120 used Euro banknotes collected in the Canary Islands (Spain). Most of the banknotes analyzed showed detectable drug residues (92.5%). Cocaine was the most frequently detected drug, present in approximately 90% of the samples. In addition, 75%, 35%, and 15% of the banknotes showed residues of amphetamine derivatives, opiates, and benzodiazepines, respectively. An average of three drug residues per banknote was detected. In summary, the presence of drug residues in banknotes could be useful as tracer for drugs prevalence.  相似文献

透过审限耗费角度的实证研究可以发现,我国基层法院刑事审判程序具有如下特征:庭前程序的"事务化",庭前程序沦为纯粹的案件管理活动;庭审程序的"速审化",庭审时间耗费少,庭审节奏明快;庭后程序的"中心化"与"间隔化"。传统观点认为,我国刑事审限制度具有人权保障和效率提升功能。通过比较和实证的考察发现,我国"贯通式"审限的真实功能为通过监控法官的审理行为,达到塑造与行政化司法制度结构相契合的审理主体的目的。  相似文献

Indented writing on thermal paper made with either one, two, or three sheets of paper above the thermal paper has been visualized by the controlled application of heat to the thermal paper at temperatures below the paper's normal color change temperature. Indentations created by applying a variable pressure to a steel letter stamp showed that, with one sheet above the thermal paper, indentations were more visible at lower pressures than with either two or three sheets above. Handwriting from 20 volunteers produced indented writing graded with most of the text clear and easy to read for all samples with one sheet above, half the samples with two sheets above and eight samples with three sheets above. Comparison with ESDA showed that, with three sheets above, there was a statistically significant difference (p < 0.01), with heating producing more samples than ESDA with most of the text clear and easy to read.  相似文献

Pharmacogenetic tests provide genetic data to tailor drug treatment and were widely predicted to be one of the first fruits of the Human Genome Project. In the mid-2000s, the US Food and Drugs Administration (FDA) became an advocate for pharmacogenetic testing, but its efforts to build a market for this new technology brought the agency into dispute with other regulatory actors over the type of evidence needed for the adoption of pharmacogenetic testing, in particular the importance of randomized control trials. The warfarin case highlights the tension between a new form of promissory regulation driven by future expectations and FDA's established role as protector of public health; and the controversy can be conceptualized as a struggle over regulatory epistemologies within a complex polycentric regulatory space. Our case study addresses two themes central to the burgeoning scholarship on the governance of emergent science and technologies (EST): the political economy of regulation, in particular the role that regulators play in creating markets for EST; and the epistemological politics of regulatory science, in particular the controversy that arises when regulators modify scientific standards to accommodate EST. Linking these two themes is the concept of promissory regulation: the idea that regulatory policy may be shaped by an institutional commitment to the transformational potential of EST. This concept sheds new light on the neo-mercantilist nature of contemporary regulatory capitalism.  相似文献

The post-World War II Australian military war crimes trials of Japanese from 1945–51 have been criticised for using a rule of evidence considerably relaxed from the ordinary requirements of a criminal trial, one that did not require witnesses to give evidence in person. Circumstantial evidence suggests that, in relation to a trial held in Darwin in March 1946 for war crimes committed in Timor, the secretive Special Operations Australia, otherwise known as the Services Reconnaissance Department (SRD), took advantage of the rule. This article argues that the SRD did not allow their members to give evidence in person in an attempt to control and limit the dissemination of information about their operational and security failures in Timor from 1943–45. The SRD operation was adjudged by its own official historian as displaying ‘gross inefficiency and criminal negligence’. While the SRD’s failures were known to select personnel at the time, access restrictions to archival records in the post-war period, including the war crimes trials, meant that the extent of its failures and how it appeared to manage knowledge of them has not been widely known.  相似文献

目的 系统评价针刺与牵引相比较治疗神经根型颈椎病(cervical spondylotic radiculopathy,CSR)的疗效和安全性。方法 广泛检索国内外各数据库中针刺与牵引治疗CSR的随机对照试验。严格按最新版Cochrane系统评价员手册5.1进行方法学质量评价并计算其效应量,进行Meta分析或描述性分析。结果 14个研究包括1 542例病例被纳入,结果显示针刺治疗CSR是安全的;针刺治疗CSR总体疗效较牵引治疗具有优效性(RR:1.20;95% CI:1.13~1.27 vs RR:1.14;95% CI:1.09~1.20)。针刺较牵引对CSR患者更具镇痛效果,且能减少复发。结论 针刺较牵引治疗CSR具有优越性,但证据等级较低,结论并不可靠。  相似文献

[摘要]目的 系统评价丹红注射液联合西药常规治疗不稳定型心绞痛的有效性与安全性。方法 检索PubMed、Medline、中国期刊全文数据库、万方数据知识服务平台中丹红注射液联合西药常规治疗不稳定型心绞痛的临床随机对照试验文献,按照Cochrane协作网推荐的方法评价纳入研究文献的质量后,采用RevMan 4.2软件进行Meta分析。结果 经筛选纳入23篇文献,共2 675例,其中治疗组(丹红注射液联合西药常规治疗)1 382例,对照组(单纯西药治疗)1 293例。各研究基线情况具有可比性。Meta分析结果显示:丹红注射液加西药常规治疗在提高心电图疗效[RR=2.84, 95% CI(2.28,3.55)]、心绞痛疗效[RR=4.13,95% CI(3.12,5.47)],升高高密度脂蛋白-胆固醇[high density lipoprotein-cholesterol, HDL-C)(WMD=0.29,95% CI(0.05,0.52)],降低低密度脂蛋白-胆固醇(low density lipoprotein-cholesterol, LDL-C)[WMD=-0.98, 95% CI(-1.33,-0.63)]和高敏C反应蛋白(high sensitive C-reactive protein, hs-CRP)[WMD=-1.42, 95% CI(-2.18, -0.65)]方面均优于西药常规治疗组。结论 丹红注射液联合西药常规治疗在改善不稳定型心绞痛患者的心电图疗效,升高HDL-C,降低LDL-C和hs-CRP水平方面优于对照组。受纳入文献质量的限制,本研究结论尚需更多高质量大样本的临床随机双盲对照研究加以验证。  相似文献

目的 观察比较通督调神针法结合夹脊穴与单纯通督调神针法治疗脑卒中后痉挛性瘫痪的疗效差异。方法 将61例患者随机分为观察组(通督调神针法结合夹脊穴)31例和对照组(单纯通督调神针法)30例,两组患者均给予康复治疗,对照组针刺取督脉穴百会、风府、水沟、大椎、至阳、腰阳关为主穴;观察组在对照组基础上结合夹脊穴针刺,取颈2—7、腰1—5夹脊穴,双侧交替针刺,每日针刺1次,每次40 min,每周6次,共治疗4周。两组患者均采用简易Fugl- Meyer运动功能量表和修订的Barthel指数(Barthel index,BI)量表评定运动功能,比较两组的疗效差异。结果 治疗4周后,观察组肢体痉挛改善程度与对照组相当,差异无统计学意义(P>0.05);两组治疗后Fugl- Meyer和BI评分均较治疗前显著升高(P<0.05),观察组治疗后Fugl- Meyer和BI评分较对照组升高更为显著(P<0.05)。结论 通督调神针法结合夹脊穴在改善脑卒中后痉挛性瘫痪患者的痉挛状态方面与单纯通督调神针法疗效相当,但在提高肢体运动功能和日常生活活动能力方面,通督调神针法结合夹脊穴均优于单纯通督调神针法。  相似文献
