Acetone presence in human biological specimens can result from exogenous administration or endogenous production, resulting from diabetes, dietary composition, alcoholism, and stress response. Victims of drug-facilitated sexual assaults (DFSA) are understood to experience enhanced stress. At the Harris County Institute of Forensic Sciences (HCIFS), DFSA drug testing includes analysis of volatile compounds, ethanol, methanol, isopropanol, and acetone, by headspace gas chromatography/flame ionization detection. The prevalence of acetone-positive specimens in DFSA casework has been observed to exceed that of other human performance case types. In this report, DFSA cases received between 2019 and 2021 (n = 393) were reviewed and 41 acetone-positive cases were detailed. Overall, nearly 11% of the DFSA cases had acetone-positive blood or urine specimens, where 3% identified acetone only, 6% identified acetone and other drug(s), and 2% identified acetone, ethanol, and other drug(s). Acetone concentrations ranged from 0.010 to 0.147 g/100 mL in urine. Other drugs such as nor-carboxy-Δ9-tetrahydrocannabinol, amphetamine, methamphetamine, ethanol, and benzoylecgonine were commonly detected. Elevated stress response encountered during DFSAs may facilitate the mechanism behind enhanced acetone production leading to increased identification. Limited availability of victim medical history precludes understanding the contribution of other disease states or physiological conditions. Nonetheless, the identification of acetone in DFSA specimens supports its potential as a biomarker of trauma in forensic toxicology casework and warrants future research within the community. 相似文献

Extending prior research regarding victim injury during sexual assault, the current study employed mixed-methods sequential explanatory research design to identify predictors of victim injury and victim death in 361 attempted and completed sexual assaults committed by 72 repeat sex offenders who assaulted strangers. Results from multinomial path analysis indicated that being female and offender coercion increased the likelihood of victim resistance, which in turn elevated the likelihood of victim injury. Divergent from the predictors of victim injury, the risk of victim death increased with victim age, offender alcohol use, and offender weapon possession. Exploratory analyses suggest that certain weapons resulted in higher probability of victim injury or victim death within the context of victim resistance. Exploratory analysis of qualitative data indicated that crime event order was not uniform—in some cases victim resistance preceded victim injury and in some assaults victim injury occurred prior to or was unrelated to victim resistance. The study findings highlight the need for further investigation of victim survival strategies when offenders possess different types of weapons. 相似文献

This study describes the risk factors associated with experiencing and committing sexual aggression among a sample of male and female adolescents. High school students completed a questionnaire containing a revised form of the Sexual Experiences Survey to assess sexual victimization and offending experiences. Ordinal regression equations were estimated separately for male and female students, regressing background characteristics, dating behaviors, and attitudinal scales on sexual victimization (for females) or offending (for males). Nearly half (48%) of the females report experiencing sexual aggression, and one-third (34%) of males admit committing this type of offending. Regression analyses show that the likelihood of reporting victimization/offending increases among females who report dating more frequently during the past month, among both males and females who report dating more different people during the past 6 months, and among older males. Females who report their religious affiliation as Protestants compared to those with no religious affiliation, and those planning to attend college are less likely to report victimization. Among the males, rejecting rape stereotypes and having more accurate legal knowledge regarding rape are related to reduced likelihoods of reporting sexual offending. Implications for improving sexual assault educational programs for adolescents are discussed. 相似文献

After forensic psychiatry was firmly established in Sweden in the 1930s, many rapists and individuals charged with assaulting children underwent a forensic psychiatric examination. The physicians found that most of them had not been “in control” of their senses or not “in complete control” of their senses at the time of the crime. If the court ordered a forensic psychiatric examination, the defendant had a very good chance of either being discharged or having his sentence reduced considerably. By the 1950s psychological perspectives began to dominate in forensic psychiatry. In the forensic records of the 1950s we can notice a shift from a biomedical to a socio-psychological perspective, and crime was increasingly related to conditions that were not seen as mental derangement from a legal point of view. As a result, it became less and less common, from the 1950s onwards, for sentences to be commuted or defendants discharged. 相似文献

ABSTRACTBystander intervention has been an effective strategy for crime prevention and has been successful in the context of campus sexual assault. Less is known about the extent to which individual-level factors correlate with intervention behavior in situations of intimate partner violence (IPV) and sexual harassment. The present study used a sample of 377 undergraduate student surveys on a campus without a bystander intervention program to examine the impact of individual-level participant factors on direct intervention across sexual assault, IPV, and sexual harassment scenarios. Findings demonstrated statistically significant differences where positive bystander attitudes and violence prevention efficacy correlated with direct intervention for sexual assault; positive bystander attitudes, personality extroversion, and exposure to a victim increased intervention behavior in an IPV scenario, and positive bystander attitudes and violence prevention efficacy increased direct intervention and lifetime experience of IPV decreased direct intervention in a sexual harassment scenario. Research and policy implications are discussed. 相似文献

This study contributed to the data about same-sex relationship violence with a large sample (n = 499) of ethnically diverse gay men, lesbians, and bisexual and transgendered people. Physical violence was reported in 9% of current and 32% of past relationships. One percent of participants had experienced forced sex in their current relationship. Nine percent reported this experience in past relationships. Emotional abuse was reported by 83% of the participants. Women reported higher frequencies than men for physical abuse, coercion, shame, threats, and use of children for control. Across types of abuse, ethnic differences emerged regarding physical abuse and coercion. Differences across age groups were found regarding coercion, shame, and use of children as tools. Higher income was correlated with increased threats, stalking, sexual, physical, and financial abuses. Preliminary patterns of same-sex relationship abuses were examined for bisexual and transgendered people. 相似文献

近年来性侵幼女犯罪案件频发已经引令人瞩目,究其原因是多方面的,社会道德沦丧致使道德底线崩溃、传统文化的心理模铸、职业道德意识淡漠部分幼儿监管不到位、防性侵意识弱、不少施暴者应该说有着猎奇甚至是变态心理、家丑不可外扬思想作怪等等不一而足。这就要求我们必须有针对性地采取防范措施,严惩犯罪犯罪嫌疑人,坚决杜绝类似事件的发生,保持高压的态势,在人们的心里筑起一道不可逾越的鸿沟,让胆敢以身试法之人得到应有的下场;细化和完善有关的法律法规,使不法分子无机可乘;加强职业道德建设,设置更高更合理的选人门槛和用人评价机制,注重从业人员道德品格的考核和评价;加强对于未成年孩子的安全意识的教育和引导。 相似文献

Pursuant to the Polish Weapons and Ammunitions Law, muzzle‐loading black powder weapons, manufactured before 1885, or their replicas, as well as suitable projectiles, can be possessed legally without registration and special licenses. The aim of the study was to assess the penetration depth of projectiles fired from a black powder weapon, replica of Colt Navy of 1851, in 20% gelatin blocks and to compare the obtained results with the actual injuries found on autopsy of a 78‐year‐old man who had committed suicide. In the experiments, we used the black powder weapon and ammunitions, as well as gelatin blocks serving as a soft tissue model. We ascertained that solid spherical projectiles fired from black powder weapons cause extensive injuries, especially in the initial segment of the wound canal. Additionally, based on the presence and location of the wad in the wound canal, the distance from which the shot was fired can be determined. 相似文献
