The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data. 相似文献

Abstract: Most humans possess 24 presacral vertebrae composed of seven cervicals, 12 thoracics, and five lumbars. However, variation from this standard pattern exists. The purpose of this study was to test the effect of congenital vertebral numerical variation on anatomical stature estimates and to recommend appropriate procedures when such variation occurs. Our sample consists of 41 individuals with unusual vertebral count patterns and known cadaveric statures from the Smithsonian’s Terry Collection. Raxter et al. published a revised Fully anatomical technique in 2006 and we used this to estimate living stature. Based on our results, we recommend using the standard anatomical technique to reconstruct stature, regardless of vertebral pattern. However, when an individual possesses six sacral segments together with a normal number of presacral vertebrae, we recommend the addition of a slight correction factor of 1.3 cm or 0.8% of estimated stature. 相似文献

The purpose of the study was to estimate associations between citizenship status and arrest for crimes among male arrestees.
The primary hypothesis was that citizenship status (a rough proxy for immigration) has significant effects on arrest for violent
personal crimes, property crimes, and four other selected offenses. Data were derived from the Arrestee Drug Abuse Monitoring
(ADAM) Program for the years 2000 through 2002 inclusive. Our sample comprised male arrestees only. Logistic regression models
were fitted to the data to estimate the citizenship status-crime relationship. Results showed no significant association between
citizenship status and arrest for violent crimes. Non-citizens were 15% less likely than citizens to be arrested for property
crimes; they were also less likely to be arrested for weapons offenses and drug offenses. Non-citizens were much less likely
to test positive on NIDA-5 drugs than citizens. Non-citizens were, however, 50% more likely than citizens to be arrested for
forgery/counterfeiting. It was concluded that public perceptions about the relationship of citizenship status to criminal
behavior may be exaggerated and may not be borne out by empirical evidence. Limitations of the study are pointed out, including
the fact that in the ADAM data, naturalized immigrants are lumped together with native born citizens. 相似文献

ABSTRACTChild welfare workforces across the nation are experiencing high turnover and have for decades. The chronic cost of turnover makes efforts to increase retention crucial. The Title IV-E education stipend program is one way that many states employ to improve their child welfare worker tenure. Through qualitative interviews, this study examines Title IV-E graduates’ experiences and perceptions of preparedness for working in child welfare agencies. Examining how the responses of stayers and leavers differ and assessing similarities collectively can inform educational and agency enhancements to improve services, as well as worker competence and retention. 相似文献

ABSTRACTAssociations between specific motivations for animal cruelty, particular methods of animal cruelty and different facets of impulsivity were explored among 130 undergraduate students. Participants completed an adapted version of the Boat Inventory on Animal-Related Experiences (BIARE) which asked participants to state whether they had intentionally harmed or killed an animal, the species of animal(s) involved, their motivations for harming or killing the animal(s) and the method(s) used. Participants also completed the Impulsive Behavior scale (UPPS-P) which assesses five facets of impulsivity. Over half of the sample (55%) reported committing at least one act of animal cruelty, and dogs were the most commonly abused species of animal. The most frequently reported motivations were Prejudice, Amusement, Control (of an animal), and Retaliation (against an animal), and the most frequently reported methods were Beating/Kicking, Squashing, Throwing an object at an animal, Shooting, Drowning and Burning. Significant associations were found between particular motivations and methods, as well as between particular methods of animal cruelty and facets of impulsivity. Findings have implications for theoretical models of animal cruelty perpetration as well as offender assessment and treatment. 相似文献

Whilst studies refer to the community impact of Organized Crime (OC), no survey currently exists to examine the views of those citizens who reside in areas where Organized Crime Groups (OCGs) proliferate. 431 questionnaires from households co-existing in high density OCGs areas were analysed in relation to: a) demographic information; b) views on the community and the police; and c) how they expected other residents to react to illegal incidents. Overall respondents thought the average citizen would refuse to intervene in 10% - 48% of illegal incidents, with the specific case influencing whether and how they would respond. The analysis then compared three communities who lived in high density OCG areas with a control community (n?=?343). The ‘OCG’ communities were more likely to report low collective efficacy and were generally least likely to expect their neighbours to confront a crime in action. Conversely, whilst the control group showed higher levels of collective efficacy and expected the average resident to be more likely in confronting illegal behaviour, this trend did not extend to street drug dealing and serious crime associated with OC. The study discusses the unreported intimidation associated with OCGs and the challenges of policing hostile environments. 相似文献

Abstract Ninety-one college subjects listened to Cognitive Interviews (CI) and Standard police interviews of 7-year old children who were attempting to describe an earlier incident of playing a game of Simon Says. The subjects evaluated the witness's credibility and also the interviewer's manipulativeness. The perceived credibility of the witness was not affected by the type of interview, i.e., the CI did not render the witness unduly credible. In addition, the CI interviewer was judged to be less manipulative than the Standard police interviewer. These results were discussed in light of some potential legal concerns about using the CI. 相似文献

Shared parenting is premised on both working parents having the right to care. However, the work–family conflict at the EU level has traditionally focused on working mothers. This was reinforced in Hofmann v Barmer Ersatzkasse [1986] 1 CMLR 242 and Commission v Italy [1984] 3 CMLR 169, and in the enactment and application of the Parental Leave Directive 96/34/EC. In both instances, fathers' role in childcare has been secondary, at best, to that of mothers. The question of shared parenting, and enabling all working parents to care, underpins proposals to amend the Pregnant Workers Directive 92/85/EEC and the revised Parental Leave Directive 2010/18/EU. This article examines the development of EU work–family policies with reference to Fineman's notion of family care, and the right to care for all working parents. It considers whether a more defined role for fathers is beginning to emerge or maternal care is further entrenched. 相似文献

AbstractThis study explored a sample of 244 UK adult male offenders convicted of offences involving indecent images of children (IIOC): 120 had a previous contact child sexual offence (defined as dual offenders) and 124 had no evidence of an offence against a child (defined as non-contact offenders). Offender groups were compared regarding their socio-demographic characteristics, previous convictions and IIOC possession. Key discriminatory factors that differentiated dual offenders were: access to children, previous offence history, sexual grooming and possession of IIOC that depicts similar-aged victims. In contrast, non-contact offenders could be identified from their greater amount and wider range of IIOC possession. The results suggest a homology between Internet behaviours, IIOC possession and victim selection. Implications for law enforcement agencies are discussed in terms of assisting investigative prioritisation by identifying those most at risk of committing sexual abuse against children. 相似文献

Abstract This study examines the effect of victim age, victim attractiveness, the victim's abuse history and respondent gender have on attributions of blame and credibility towards a female victim in a hypothetical child sexual abuse case. A total of 397 respondents from a community sample read a hypothetical child sexual abuse (CSA) scenario in which victim age, victim attractiveness and the victim's abuse history were manipulated. Respondents then completed a 16-item blame attribution questionnaire. Several predictions were made. First, a 10-year-old victim would be deemed less blameworthy and more credible than a 15-year-old victim. Secondly, an attractive victim would be viewed more positively, and attributed less blame, than an unattractive victim. Thirdly, a victim with previous history of being sexual abused—either by the same or different perpetrators—would be deemed more culpable for their own CSA than a first time victims. Finally, female respondents were expected to take a more pro-victim and anti-perpetrator stance than males. Whilst comparatively few differences were found across victim attractiveness and abuse history. Overall findings were broadly in line with predictions. It was concluded that victim age and respondent gender play particularly important roles in the attribution of blame towards victims and perpetrators of child sexual abuse. 相似文献
