Feasibility of Canine Detection of Mass Storage Devices: A Study of Volatile Organic Compounds Emanating from Electronic Devices Using Solid Phase Microextraction 下载免费PDF全文
Lauryn E. DeGreeff Ph.D. Michelle Cerreta Ph.D. Mark Rispoli J.D. 《Journal of forensic sciences》2017,62(6):1613-1616
Detection of canines are well‐known to be valuable in the location of contraband, such as explosives or narcotics. More recently, canines have been trained and utilized in the detection of concealed mass storage devices that might contain evidence of illegal activity such as child pornography. To lay the analytical foundation for this detection work, research was carried out to determine the volatile organic compounds associated with mass storage devices (MSD) that could be used by trained canines for detection. Headspace analysis of a variety of electronic devices was performed using solid phase microextraction (SPME) with gas chromatography/mass spectrometry (GC/MS). Analyses found several volatile compounds common to SIM and SD cards, as well as USB drives, including 2‐propenenitrile, styrene, isophorone, hydroxycyclohexyl phenyl ketone, and 2‐furanmethanol, tetrahydro. Results indicated that mass storage devices do have a characteristic odor profile making detection with minimal false alerts feasible for trained canines. 相似文献

The present experiment examined how the seating position of an interpreter during investigative interviews affects information elicitation and cues to deceit. A total of 60 native English speakers were interviewed in English and 200 non-native English speakers were interviewed in English (a non-native language) or through an interpreter who either sat next to the interviewer, behind the interviewee or interpreted via the telephone. Interviewees either lied or told the truth about a mock security meeting they watched. Interviewees who spoke in their native language provided more detail than interviewees who spoke in their native language through an interpreter or in a non-native language (English) without an interpreter. The latter groups did not differ. Additionally, the amount of detail differentiated truth tellers from liars in all conditions and interviewees found the presence of an interpreter to be a largely positive experience. The interpreter’s seating position had no effect on the findings. 相似文献

The dearth of studies investigating diagnostic stability among offenders, and diagnostic stability being important from the patient’s mental health perspective, as well as from a public health, training and research standpoint, highlights the need to evaluate lifetime stability of ICD-10 psychiatric diagnoses for offenders in community and prison settings. A case-linkage design linked a two-year population-based cohort of male-sentenced prisoners with a state-wide psychiatric register (23,742 psychiatric consultations). Four measures of diagnostic stability were calculated for each setting as well as across settings, for all offenders who received at least two psychiatric diagnoses. Temporal consistency was moderate for schizophrenia spectrum disorders and low for affective, anxiety and personality disorders, and was higher in prison setting than community settings. Diagnostic instability highlights that the course of mental illness and clinical features among offenders may genuinely vary over time, across community and prison settings and may lead to complexities regarding psychiatric care for this population 相似文献

Scholars of mass incarceration point to the 1970s as a pivotal turning point in U.S. penal history, marked by a shift toward more punitive policies and a consensus that “nothing works” in rehabilitating inmates. However, while there has been extensive research on changes in policy makers' rhetoric, sentencing policy, and incarceration rates, scholars know very little about changes in the actual practices of punishment and prisoner rehabilitation. Using nationally representative data for U.S. state prisons, this article demonstrates that there were no major changes in investments in specialized facilities, funding for inmate services–related staff, or program participation rates throughout the late 1970s and the 1980s. Not until the 1990s, more than a decade after the start of the punitive era, did patterns of inmate services change, as investments in programming switched from academic to reentry‐related programs. These findings suggest that there is a large gap between rhetoric and reality in the case of inmate services and that since the 1990s, inmate “rehabilitation” has increasingly become equated with reentry‐related life skills programs. 相似文献

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed. 相似文献

This article is based on an ethnographic study of a cottage for violent offenders in one state's maximum-security training school. Staff members working in the cottage were the institution's front line in its attempts to hold the youth accountable for their crimes while also trying to resocialize and rehabilitate young men who were growing up with few conforming role models. As such, cottage staff members were put in the difficult position of juggling their roles as corrections officers, counselors, and surrogate parents. To effectively do their job, they had to find ways to balance the rhetoric of rehabilitation with the punitive reality of daily life in the institution. This article details the juvenile justice career paths of the staff members in the cottage and provides a sociological analysis of the roles, responsibilities, and interactions of the staff members with each other and with the young men in their care. 相似文献

'When We Wanted to Talk About Rape': Silencing Sexual Violence at the Special Court for Sierra Leone
This article explores the legal and psychological ramificationsarising from the exclusion of evidence of sexual violence duringthe Civil Defence Forces (CDF) case at the Special Court forSierra Leone. Using empirical findings from post-trial interviewsconducted with the ten victim-witnesses who were originallyto testify, we juxtapose what the Special Court allowed thewomen to say, and what the women themselves wanted to say. Froma legal perspective, we then critique the Trial Chamber's reasonsfor excluding the evidence and question the legal bases uponwhich the women were silenced, arguing that wider and widercircles of the women's experience were removed from the Court'srecords despite there being ample authority at an internationallevel to support inclusion. We further look at the genderedbiases in international criminal law and how expedience andefficiency usurped the significance of prosecuting crimes ofsexual violence in this instance. From a psychological perspective,we discuss the consequences that the act of silencing had forthe witnesses, and argue that a more emotionally sensitive understandingof the Court's notion of protection is required. 相似文献

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
