Contaminated Confessions Revisited

A second wave of false confessions is cresting. In the first twenty-one years of post-conviction DNA testing, 250 innocent people were exonerated, forty of which had falsely confessed. Those false confessions attracted sustained public attention from judges, law enforcement, policymakers, and the media. Those exonerations not only showed that false confessions can happen, but did more by shedding light on the problem of confession contamination, in which details of the crime are disclosed to suspects during the interrogation process. As a result, false confessions can appear deceptively rich, detailed, and accurate. In just the last five years, there has been a new surge in false confessions — a set of twenty-six more false confessions among DNA exonerations. All but two of these most recent confessions included crime scene details corroborated by crime scene information. Illustrating the power of contaminated false confessions, in nine of the cases, defendants were convicted despite DNA tests that excluded them at the time. As a result, this second wave of false confessions should cause even more alarm than the first. In the vast majority of cases there is no evidence to test using DNA. Unless a scientific framework is adopted to regulate interrogations, including by requiring recording of entire interrogations, overhauling interrogation methods, providing for judicial review of reliability at trial, and informing jurors with expert testimony, the insidious problems of confession contamination will persist

Designing and Building immersive education spaces using Project Wonderland: from pedagogy through to practice

This paper presents work on the JISC funded SIMiLLE project to build a culturally sensitive virtual world to support language learning. This builds on the MiRTLE project (funded by Sun Microsystems), which created a mixed-reality space for teaching and learning. The aim of the SIMiLLE project is to investigate the technical feasibility and pedagogical value of using virtual environments to provide a realistic socio-cultural setting and content for language learning interaction. The paper starts by providing some background information on the Wonderland platform and the MiRTLE project, and then outlines the requirements for SIMiLLE, and how these requirements will be supported through the use of a virtual world based on Project Wonderland. We then present our plans for the evaluation of the system, with a particular focus on the importance of incorporating pedagogy into the design of these systems, and how we can support good practice with the ever-growing use of 3D virtual environments in formalised education

Computer Supported Strategic Management

This paper presents an overview of the essential components of effective strategic management and a detailed description of the methodology for leading an organization through the strategic management process. This process can be extremely time consuming and can easily fall victim to pep rally thinking, rather than producing useful critical evaluation.The authors have successfully used GroupSystems software, one of a limited number of software products designed to support meetings, to significantly reduce the amoimt of time required for meetings and to improve the level of independent, unbiased input from participants. The parallel processing afforded by the software typically reduced meeting time from one-third to one-half that of face-to-face meetings, and the input anonymity feature of the software encouraged insightful candor from participants. The GroupSystems seuip for each of the computer-supported meetings is detailed to illustrate how software of this type can be used to make strategic management efforts more successful.

PlantID – DNA-based identification of multiple medicinal plants in complex mixtures

Background An efficient method for the identification of medicinal plant products is now a priority as the global demand increases. This study aims to develop a DNA-based method for the identification and authentication of plant species that can be implemented in the industry to aid compliance with regulations, based upon the economically important Hypericum perforatum L. (St John’s Wort or Guan ye Lian Qiao). Methods The ITS regions of several Hypericum species were analysed to identify the most divergent regions and PCR primers were designed to anneal specifically to these regions in the different Hypericum species. Candidate primers were selected such that the amplicon produced by each species-specific reaction differed in size. The use of fluorescently labelled primers enabled these products to be resolved by capillary electrophoresis. Results Four closely related Hypericum species were detected simultaneously and independently in one reaction. Each species could be identified individually and in any combination. The introduction of three more closely related species to the test had no effect on the results. Highly processed commercial plant material was identified, despite the potential complications of DNA degradation in such samples. Conclusion This technique can detect the presence of an expected plant material and adulterant materials in one reaction. The method could be simply applied to other medicinal plants and their problem adulterants

Symmetry of Resting Tone, Alignment, and Strength in the Pelvic Region

Background: Resting tone contributes substantially to postural alignment and stability of the spine. Muscles attached to the axial skeleton, specifically muscles crossing the SI joint such as the gluteal muscles and latissimus dorsi, could contribute to pain and dysfunction if significant differences in side-to-side resting tone exist. While studies have observed side-to-side differences in resting tone of the biceps brachii, no current studies have assessed resting tone differences across the SI joint. Methods and Measures: Data on resting tone, pelvic asymmetry, and strength were collected using the MyotonPRO myometer, PALM palpation meter, and a strength dynamometer respectively from 30 asymptomatic. Results: Normative data were collected for strength of the iliopsoas, rectus femoris, latissimus dorsi, gluteus maximus, gluteus medius, hamstrings, and hip adductors. The MyotonPRO tested for bilateral tone, elasticity, creep, stiffness, and relaxation of the same muscles. Measures of pelvic alignment for tilt (ranging from 2° to 17° of anteriorly) were collected as well as symmetry of PSIS, ASIS, and iliac crest height (ranging -3° to 3° of difference). Conclusions: Side-to-side differences in resting tone, elasticity, creep, stiffness, relaxation, strength, and pelvic symmetry were noted in asymptomatic participants for SI and low back pain. This data provides information to be used in future studies for: determining correlation among tone, alignment, strength, and dysfunction; identifying impairments associated with dysfunction and response to interventions; and guiding impairment-based treatment options

The Lisbon Treaty and the British Press a Corpus-Based Contrastive Analysis of Evaluation Resources

Evaluation plays an important role in understanding speakers or writers’ attitude towards an event or their feelings about entities and propositions (Hunston and Thompson 2000). Bednarek (2006) argues that evaluation pervades human behaviour and is linked to our beliefs. She also points out the importance of evaluation in actual discourse as it is impossible for any human being not to judge or be completely objective on a particular event. Given the nature of evaluation to be linked to our beliefs, it can be argued that there is a close relationship between evaluation and metaphor as metaphor analysis ‘‘is often, then, an exploration of the inner subjectivity of speakers – what it is that is unique to their perception of the world – and forms the basis for their response to particular situations and particular ideas’’ (Charteris-Black 2004: 11). Against this background, the present paper starts from the findings of a research project on conceptual metaphor analysis in the British press related to the Lisbon Treaty debate and focuses on the evaluative lexis that has often been found to collocate or co-occur with the linguistic expressions of the conceptual conflict and movement metaphors analysed. The evaluative adjectives we are particularly interested in are bullying, desperate, reluctant, arrogant, frightening, surprised, insistent. The evaluative verbs that we intend to explore are admit, blast, praise. However, all the other evaluative terms that might come up to light and have a significant role in the analysis of the event will be taken into account. The aim of this paper is to explore, through the methodology of Corpus Linguistics, how the British press uses the evaluative resources to construe the event of ratification and to what extent it presents a similar description or attributes similar roles to the European leaders and uses both metaphors and evaluation to create a coherent text and image of the ratification issue
