Developing regulatory standards for the concept of security in online dispute resolution systems

Online dispute resolution (ODR) has improved access to justice in the digital world. ODR users benefit from faster and cheaper dispute resolution mechanisms compared to traditional litigation and Alternative Dispute Resolution. There are few and quite varied regulatory systems for ODR.This research aims to develop a set of standards to measure the concept of security and to increase the consistency of security in ODR systems. An exploratory mixed method approach is used, involving a quantitative (survey) and mainly qualitative approach (face-to-face interviews) for gathering data. We identify three elements of information security, privacy, and authentication as standards for an appropriate ODR legal framework. Finally, these findings led to practical implications for policy makers and regulators.     

Fragrance transfer between fabrics for forensic reconstruction applications

Sexual assault is a serious crime that often has low conviction rates. Recent literature has demonstrated that there is potential for fragrances to be valuable in forensic reconstructions where there has been contact between individuals. However, developing appropriate evidence bases for understanding the nature of fragrance transfer in these contexts is needed. This article presents three experiments that address the transfer process of fragrances that have been transferred from a primary piece of fabric onto a secondary piece of fabric, in a manner that could occur during an assault. The three variables studied were the ageing time of the fragrances on the first fabric prior to transfer, the contact time between the two fabrics, and lastly the fabric type (of the primary material and the recipient material). The transfer was evaluated using a validated solid phase micro-extraction gas chromatography–mass spectrometry (SPME GC–MS) method. The findings demonstrated that all three variables had an impact on the transfer of fragrances between clothing fabrics. Generally, lower volatility compounds were transferred and recovered in larger amounts than higher volatility compounds. All fragrance compounds were successfully recovered from a secondary piece of fabric even when the contact time was as short as 10 s, and even when the perfume was aged on the primary fabric for as long as 48 h. The nature of the fragrance transfer also depended on the fabric type, so that a clear discrimination was observed between the fragrance transfer that occurred onto a natural fabric (cotton) and onto a synthetic fabric (polyester).     

Newspaper Reporting and Changing Perceptions of Ministerial Accountability in Australia

Throughout the developed world, there is a general perception that politicians are more corrupt than they used to be. In Australia these claims appear to be supported in recent decades by far more calls for ministers to resign. In this article we argue that the perception of declining quality in our federal government ministers is the result of much greater media attention, the rise of new controversial cross‐cutting issues and changing cultural attitudes rather than declining parliamentary and ministerial standards. We argue that the belief that politicians are more corrupt or less trustworthy than they used to be has arisen because they are now much more comprehensively reported upon; and we suggest that ministerial accountability might have been enhanced by more extensive media coverage.     

Short tandem repeat (STR) genotyping of keratinised hair. Part 1. Review of current status and knowledge gaps

We present a review of the literature on procedures for obtaining short tandem repeat (STR) genotypes from keratinised hair, being either hair shaft or telogen phase (naturally shed) hairs without associated scalp, follicle or sheath cells. Both the hair shaft and the telogen hair club have been subjected to the DNA-degrading keratinisation process and are more likely to be found at a crime scene than anagen (plucked) or catagen phase hairs. We discuss human hair structure, the human hair growth cycle, the keratinisation process and their implications for DNA extraction procedures, PCR amplification strategies and the interpretation of STR genotypes. Knowledge gaps and areas requiring research are identified and are the subject of a second article in this series.     

Validation of the Cozart microplate EIA for analysis of opiates in oral fluid

The purpose of this study was to determine the performance characteristics of the Cozart microplate EIA for detecting opiates in oral fluid from patients in a drug misuse treatment program. Oral fluid samples were collected using the Cozart RapiScan Collection System from 216 donors who were receiving treatment for their addiction and were monitored for drug abuse. A further 40 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory by using the Cozart microplate EIA for opiates and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen until analysis by GC-MS. The intra-assay precision for the Cozart microplate oral fluid EIA for opiates over 40 assays was 0.43% to 9.13% CV (within assay) and 2.9% to 9.1% CV (within day). A total of 109 samples were positive for various opiates. The Cozart microplate EIA for opiates in oral fluid, using a cut-off of 30 ng/ml morphine equivalents in neat oral fluid, had a sensitivity of 99.1 +/- 2.1% and a specificity of 94.4 +/- 2.2% versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Evaluation of the Cozart RapiScan drug test system for opiates and cocaine in oral fluid

The purpose of this study was to evaluate the efficiency of the Cozart RapiScan (CRS) drug test system for detecting opiates and cocaine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan collection system from 358 donors who were receiving treatment for their addiction and were monitored for drug misuse. A further 103 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the two-panel Cozart RapiScan cartridge for opiates and cocaine and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen at -20 degrees C until analysis by GC-MS. The overall accuracy of the CRS for both opiates and cocaine was 100%. Samples spiked at 50% above and below the cut-off consistently gave negative and positive results respectively. A total of 88 samples were positive for various opiates and 111 samples were positive for cocaine and/or its metabolites. The CRS for opiates and cocaine in oral fluid, using a cut-off of 30 ng/mL morphine or benzoylecgonine equivalents in neat oral fluid, had overall efficiencies of 98% and 99%, respectively, versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result.     

Regional Development of Small Firms in Poland

Employing a probit, logit and gompit model this paper demonstrates that small firm development, represented by a group of structural, behavioral and performance variables determine regional location in Poland. The paper uses original data that samples the small firm stratum in two contrasting regions, Pomorskie and Lubelskie. The following variables were shown to be significantly correlated with regional location: legal structure, subcontracting, technological level of the products of the firm, average wage and intention to expand turnover.     

Validation and implementation of the PowerPlex 16 BIO System STR multiplex for forensic casework

The PowerPlex 16 BIO multiplex short tandem repeat (STR) system contains the 13 CODIS loci (FGA, TPOX, D8S1179, vWA, D18S51, D21S11, TH01, D3S1358, CSF1PO, D16S539, D7S820, D13S317, and DS5S818), plus two pentanucleotide repeat loci (Penta D and Penta E) and the sex-identifying locus. Amelogenin. The PowerPlex 16 BIO System is optimized for use with the Hitachi FMBIO gel imaging systems. A consortium of seven independent laboratories collaborated to perform the studies defined by the FBI standards for performing a developmental validation, including the evaluation of sample concordance, percent stutter determination, nonprobative casework, precision, sensitivity, mixture determination, effect of substrates, the impact of environmental insults, and species specificity. All samples tested for concordance were consistent except for one sample from the Virginia Division of Forensic Science database that displayed discordance at D13S317, a locus whose primer sequence was altered. Stutter values were comparable to those of other STR multiplex systems, the precision was comparable to other multiplexes analyzed by gel electrophoresis, the DNA profiles were unchanged by the substrate upon which the blood samples were placed, and the nonprobative casework samples re-typed for the PowerPlex 16 BIO System were consistent with previous typing results. When greater than 0.125 ng of DNA was placed into the PowerPlex 16 BIO System amplification reaction, a full profile was generated by all laboratories. The mixture study results were comparable to those reported for other multiplex systems, the environmental study demonstrated a loss of larger molecular weight loci when samples were incubated at elevated temperatures for a prolonged period of time, and the only notable cross species hybridization was observed with primate DNA samples. This extensive validation work performed demonstrates that the PowerPlex 16 BIO System provides STR data of a quality comparable with other PowerPlex STR multiplex kits as well as other widely used STR multiplexes and is thus suitable for evidentiary casework analysis as well as database sample profiling.     

Motor vehicle exhaust gas suicide in Victoria, Australia 1998-2002

Motor vehicle exhaust gas suicide (MVEGS) is the second most frequent method of suicide in Victoria, Australia. It is a highly lethal method of suicide with 1.5 deaths for every hospital admission. Australian regulations require all vehicles manufactured since 1998 to have a maximum carbon monoxide exhaust emission level of 2.1 g/km, reduced from the previous level of 9.6 g/km. Information surrounding all Victorian MVEGS between 1998-2002 was analyzed to determine whether suicides occurred in vehicles with the lower emission levels. Between 1998-2002, 607 suicides by this means were recorded while just 393 hospital admissions were recorded for the same period. Mean carboxyhaemoglobin levels were significantly lower in fatalities using vehicles manufactured from 1998, however suicide still occurred in these vehicles (n = 25). The extent to which the new regulations contributed to the relatively low rate of suicide in vehicles less than 5 years old compared to their frequency in the fleet remains unknown. Based on international experience and the age of the Victorian vehicle fleet, it may take well over a decade until substantial decreases in MVEGS are observed in the absence of active preventive measures.
