A best practice model for e-consumer protection

This article outlines a set of criteria for assessing the value of e-consumer protection schemes. It is intended that it be used as a tool, for policy-makers, industry associations, corporations and consumer organisations in all jurisdictions, seeking to assess the appropriateness of their consumer protection regulation. It can be used to devise new, or improve existing, policies, and it can also be used to compare the usefulness of e-consumer protection in different jurisdictions. It commences with a brief review of existing frameworks for the protection of e-consumers, which demonstrates the need for a model that uncompromisingly presents the needs of consumers. An overview of the model is provided, followed by a presentation of the model's key features. A further section identifies the several ways in which the model can be applied in order to improve the usefulness of e-consumer protection. An earlier version of the model was published in checklist form (Clarke R. ‘A Major Impediment to B2C Success is … the Concept 'B2C' Invited Keynote, Proc. ICEC'06, Fredericton NB, Canada, 14–16 August 2006, at http://www.rogerclarke.com/EC/ICEC06.html#TNT). The present article revises and expands that checklist, and presents the rationale underlying each item in it.     

Anion Identification via Complexation with meso‐octamethylcalix(4)pyrrole and Detection Using Electrospray Ionization Mass Spectrometry*

Abstract: The routine identification of controlled substances and adulterants during forensic chemistry analysis often involves the identification of counter ions or salt forms present in an exhibit. Here, the use of the compound meso‐octamethylcalix(4)pyrrole (C4P) during salt‐form identification analysis is presented. C4P is a commercially‐available, anion‐binding agent that can be reacted with a controlled substance or adulterant, resulting in the sequestration of anionic species, usually present as counter ions to the active ingredient. Formation of noncovalent complexes between the cyclic host C4P compound and anionic guests is investigated using electrospray ionization–mass spectrometry (ESI–MS). Complexes with chloride, bromide, iodide, nitrate, and acetate are readily observed and mass spectrometry analysis provides identification via molecular weight characterization. Chloride and bromide complexes are also characterized by the isotopic distribution of their molecular ions. Formation of host–guest complexes is not observed for sulfate and phosphate salts, presumably due to steric hindrance and energetically unfavorable conditions.     

Ethnicity and risk for symptoms of posttraumatic stress following intimate partner violence: prevalence and predictors in European American and African American women

The present study uses a feminist theoretical framework to explore risk factors for the development of posttraumatic stress symptoms following intimate partner violence, with a community sample of 120 low-income European American and African American women. Hierarchical regression analyses were used to examine demographic, violence, and mental health variables that predict posttraumatic stress symptoms. The data reveal that African American women report lower levels of posttraumatic stress symptoms than do their European American peers. This difference was observed despite the presence of more empirically identified risk factors for African American women. Regression analyses show that symptoms of depression increase risk for posttraumatic stress for both groups. However, a difference was observed such that past victimization increase risk for only European American women, whereas amount of psychological violence in the previous year increases risk for only African American women. Potential explanations for observed ethnic differences are offered.     

The information infrastructures of 1985 and 2018: The sociotechnical context of computer law & security

This article identifies key features of the sociotechnical contexts of computer law and security at the times of this journal's establishment in 1985, and of its 200th Issue in 2018. The infrastructural elements of devices, communications, data and actuator technologies are considered first. Social actors as individuals, and in groups, communities, societies and polities, together with organisations and economies, are then interleaved with those technical elements. This provides a basis for appreciation of the very different challenges that confront us now in comparison with the early years of post-industrialism.     

Micellar electrokinetic chromatographic screening method for common sexual assault drugs administered in beverages

Recently, much attention has been given to benzodiazepines and gamma-hydroxybutyric acid (GHB) related compounds owing to their alleged widespread use as date-rape drugs. Toxicologists would greatly benefit from a screening method that allows for the simultaneous detection of both groups of substances. A new capillary electrophoresis (CE) method has been developed in the micellar mode to accomplish this separation in under 16 min using a sodium dodecyl sulfate (SDS)/sodium tetraborate/boric acid buffer with an acetonitrile organic modifier. Optimization of SDS and organic modifier concentration, along with pH, were performed on a set of standards containing eight benzodiazepines, GHB, gamma-butyrolactone, and the internal standard, sulfanilic acid. The method was shown to have a detection limit of less than 2 microg/ml for five out of eight benzodiazepines with a linear range of 2.5-100 microg/ml. The detection limit for GHB was 32 mg/ml with a linear range to 2500 microg/ml. This method was applied to the rapid analysis of spiked beverages. GHB spiked beverages were monitored after using a series of simple dilutions to determine the effects of time on the drug analysis. Possible interfering peaks from drugs of abuse and artifacts from a variety of different drink combinations were also studied in detail. A one-step liquid-liquid extraction was the only necessary sample pretreatment.
