Visualisation of fingermarks and grab impressions on fabrics. Part 1: gold/zinc vacuum metal deposition

Vacuum metal deposition (VMD) is a highly sensitive technique originally introduced for detecting latent fingermarks on smooth non-porous surfaces such as carrier bags, plastics and glass. The current study explores whether VMD can be used in the examination of clothing from physical and sexual assault cases in order to visualise identifiable fingermark ridge detail and/or palmar flexion crease detail, thus allowing potential areas to be indicated for DNA swabbing and/or to determine the sequence of events. Four different fabrics were utilised during this study - nylon, polyester, polycotton and cotton, along with 15 donors who ranged in their age and propensity to leave fingermarks, from good to medium to poor as determined by results obtained from test runs using paper and plastic carrier bags processed with VMD. Once samples were collected they were kept for a determined time (1, 2, 3, 4, 5, 6, 7, 14, 21 or 28 days) and then treated using the gold/zinc metal VMD process. From the results, it appears that greater ridge detail is visible on the smoother non-porous fabrics, such as nylon whereas on rougher porous fabrics, such as cotton, only empty prints and impressions, rather than any ridge details, were visible. All fabrics did however allow the development of touch marks that could be targeted for DNA taping thus potentially leading to a DNA profile and possible identification of a suspect.     

Academic freedom and international standards in higher education: Contestation in journalism and political science at Moscow State University

Recently two new departments, the School of Broadcast Journalism and the Department of Political Science, were created at Moscow State University while leaving the two traditional departments that engendered them intact. The result has been a contestation over academic freedom, standards, and the very definition of both disciplines at Russia’s premier university. The new departments are both closely associated with United Russia, the dominant political party in Russian politics and the political movement designed to promote the priorities and policies of Prime Minister and former President Vladimir Putin. This paper examines the self-definition of each of the four departments by means of open-ended, semi-structured interviews with faculty and content-analytic examination of curricular materials, including syllabi and assigned readings. We conclude that the newer departments are somewhat more attuned to certain aspects of the international standards of both disciplines, but demonstrate little adherence to key ethical and pedagogical norms, leaving them more susceptible to political influence.     

An examination of types of delinquency through path analysis

Relationships between father's occupation, delinquent peer association, tendency to neutralize, and self-reported delinquency are explored in a path model. Self-reported delinquency are categorized into Minor, Predatory, and Aggressive delinquency. The effect of this division is analyzed among Mexican Americans and Anglo college students (N=694). The structure of the resulting path models remained similar across these subsamples, although there was some variation in the strength of the relationships. The effect of father's occupation was minimal. The strongest relationships were between neutralization and delinquency, controlling for delinquent peers and for father's occupation, which decreased as the seriousness of the delinquency increased. Additionally, neutralization was more strongly related to delinquency among Anglos than among Mexican Americans, explaining 39% of the variation in delinquency among Anglos, but only 28% among Mexican Americans. Association with delinquent peers, however, was more strongly related to delinquency among Mexican Americans.Received his Ph.D. from Oklahoma State University.

Climate action versus inaction: balancing the costs for Gulf energy exporters

ABSTRACT

Climate change poses a strategic dilemma for oil-exporting states of the Gulf. By sapping global demand for crude oil, climate action threatens the economic rents that underpin their governance and regime legitimacy. However, the Gulf states are also among the countries most exposed to physical risks of a warming climate and thus would benefit most from reducing ongoing accumulations of carbon in the atmosphere and associated adaptation costs. In other words, the political and economic risks of climate action run counter to the physical and environmental risks. These bifurcated interests differentiate the Gulf producers from oil exporters in more temperate regions, which would experience milder short-run damage—or even benefits—from a warming climate. A successful economic diversification strategy could address both physical and economic risks but would require structural changes in rentier governance.     

Urinary excretion profiles of 11-nor-9-carboxy-Delta9-tetrahydrocannabinol. Study III. A Delta9-THC-COOH to creatinine ratio study

Huestis and Cone reported in [J. Anal. Toxicol. 22 (1998) 445] that serial monitoring of Delta9-THC-COOH/creatinine ratios in paired urine specimens collected at least 24h apart could differentiate new drug use from residual Delta(9)-THC-COOH excretion following acute marijuana use in a controlled setting. The best accuracy (85.4%) for predicting new marijuana use was for a Delta(9)-THC-COOH/creatinine ratio > or = 0.5 (dividing the Delta9-THC-COOH/creatinine ratio of specimen no. 2 by the specimen no. 1 ratio). In previous studies in this laboratory [J. Anal. Toxicol. 23 (1999) 531 and Forensic Sci. Int. 133 (2003) 26], urine specimens were collected from chronic marijuana users > or = 24 h or > = 48 h apart in an uncontrolled setting. Subjects with a history of chronic marijuana use were screened for cannabinoids with the EMIT II Plus cannabinoids assay (cut-off 50 ng/ml) followed by confirmation for Delta9-THC-COOH by GC-MS (cut-off 15 ng/ml). Creatinine was analyzed as an index of dilution. The objective of the present study was to evaluate whether creatinine corrected specimens could differentiate new marijuana or hashish use from the excretion of residual Delta(9)-THC-COOH in chronic marijuana users based on the Huestis 0.5 ratio. Urine specimens (N=376) were collected from 29 individuals > or = 96 h between urine collections. The mean urinary Delta9-THC-COOH concentration was 464.4 ng/ml, mean Delta9-THC-COOH/creatinine ratio (ng/(ml Delta9-THC-COOH mmoll creatinine)) was 36.8 and the overall mean Delta9-THC-COOH/creatinine ratio of specimen 2/mean Delta9-THC-COOH/creatinine ratio of specimen 1 was 1.37. The Huestis ratio calculation indicated new drug use in 83% of all sequentially paired urine specimens. The data were sub-divided into three groups (Groups A-C) based on mean Delta9-THC-COOH/creatinine values. Interindividual mean Delta9-THC-COOH/creatinine values ranged from 4.7 to 13.4 in Group A where 80% of paired specimens indicated new drug use (N=10) and 20.4-39.6 in Group B where 83.6% of paired specimens indicated new drug use (N=7). Individual mean Delta9-THC-COOH/creatinine values ranged from 44.2 to 120.2 in Group C where 84.5% of paired urine specimens indicated new marijuana use (N=12). Correcting Delta9-THC-COOH excretion for urinary dilution and comparing Delta9-THC-COOH/creatinine concentration ratios of sequentially paired specimens (collected > or = 96 h apart) may provide an objective indicator of ongoing marijuana or hashish use in this population.     

The incidence of drugs in drivers killed in Australian road traffic crashes

The incidence of alcohol and drugs in fatally injured drivers were determined in three Australian states; Victoria (VIC), New South Wales (NSW) and Western Australia (WA) for the period of 1990-1999. A total of 3398 driver fatalities were investigated which included 2609 car drivers, 650 motorcyclists and 139 truck drivers. Alcohol at or over 0.05 g/100ml (%) was present in 29.1% of all drivers. The highest prevalence was in car drivers (30.3%) and the lowest in truckers (8.6%). WA had the highest rate of alcohol presence of the three states (35.8%). Almost 10% of the cases involved both alcohol and drugs. Drugs (other than alcohol) were present in 26.7% of cases and psychotropic drugs in 23.5%. These drugs comprised cannabis (13.5%), opioids (4.9%), stimulants (4.1%), benzodiazepines (4.1%) and other psychotropic drugs (2.7%). 8.5% of all drivers tested positive for Delta(9)-tetrahydrocannabinol (THC) and the balance of cannabis positive drivers were positive to only the 11-nor-Delta(9)-tetrahydrocannabinol-9-carboxylic acid (carboxy-THC) metabolite. The range of THC blood concentrations in drivers was 0.1-228 ng/ml, with a median of 9 ng/ml. Opioids consisted mainly of morphine (n=84), codeine (n=89) and methadone (n=33), while stimulants consisted mainly of methamphetamine (n=51), MDMA (n=6), cocaine (n=5), and the ephedrines (n=61). The prevalence of drugs increased over the decade, particularly cannabis and opioids, while alcohol decreased. Cannabis had a larger prevalence in motorcyclists (22.2%), whereas stimulants had a much larger presence in truckers (23%).     

A Critical Appraisal of the Statecraft Interpretation

This article subjects the Statecraft interpretation to critical assessment. It argues that, while Bulpitt has provided a parsimonious and stimulating contribution to our understanding of British politics, his work needs to be developed. More specifically, although the Statecraft thesis evolved out of Bulpitt’s concerns with the methodology of political science, a neglect of ontological and epistemological questions has led it to propound explanations which are both reductionist and insensitive to empirical criticism. The article concludes by suggesting ways in which the Statecraft interpretation can be developed to take account of these weaknesses.     

Re-imagining the Global Colour Line: The Bolt Case and the Politics of Whiteness

This paper revisits the controversy generated by a series of publications in 2009 by prominent Australian journalist Andrew Bolt. The overall argument is that the controversy generated by the Bolt case contributed to a reimagining of a twenty-first century version of the global colour line. Bolt's articles rested on a “racial grammar of whiteness” that enabled him simultaneously to assert and mask the hegemonic naturalness of whiteness. A racial grammar of whiteness mediates what people take to be the norm in representations and writings about the natures, roles and attributes of whites and non-whites in social situations and the social relations appropriate to them. It enables such views to be presented as just so much common-sense. Demonstrating this racial grammar at work is important because his articles appeared to echo an earlier era's narratives about race, power and privilege that were themselves informed by the global colour line, and which culminated in the now defunct White Australia Policy. The paper explores how those echoes were given substance within Bolt's articles and the subsequent court case about them, and how this contributed to a reimagining of the global colour line.     

Situating tenure,capital and finance in farmland relations: implications for stewardship and agroecological health in Ontario,Canada

Farmers in Canada are older and more capitalized than ever before. Meanwhile, farmland values continue to rise. These forces together are generating unprecedented shifts in farmland relations, marked by increasing reliance on rental tenure and the rise of hybrid owner–renter consolidating farmers. This paper explores these dynamics in Ontario and asks how they are impacting on-farm agroecological stewardship. To do so, we begin with a review of the land and property relations literature as well as farmland and agricultural change in Ontario. We then briefly review agroecological issues and concepts that are important for linking on-farm agroecological health to aformentioned farmland and agricultural changes. From here, we use survey, interview and soil sample data collected from grain farmers across Ontario to elucidate relatively new shifts in land tenure and use dynamics. We argue that this complex set of forces is interacting to produce an appealing set of conditions for financial investors, while restricting access to farmland for less-capitalized farmers. We then show how these shifts are divesting capital and attention from agroecological health. We conclude with a reflection on how the state has been mediating and contributing to these dynamics, and urgently call for land policy that prioritizes social and ecological principals.
