Exoffender Accounts of Successful Reentry from Prison
Reentry research often focuses on those who have recidivated, with little work addressing the experiences of those who successfully reintegrate into their communities. This study examines individual accounts of successful transitions from prison to community in the months and years postrelease. Interview data point to three metanarratives used to make sense of reentry: as reverence, as reunification, and as reconstruction. In different ways, each narrative centers on connections to important others through faith, family, or community. We discuss the legitimacy of the self-narratives offered, and add to a growing body of work exploring reentry via the lens of the exoffender
Suppression of displacement in severely slowed saccades
Severely slowed saccades in <I>spinocerebellar ataxia</I> have previously been shown to be at least partially closed-loop in nature: their long duration means that they can be modified in-flight in response to intrasaccadic target movements. In this study, a woman with these pathologically slowed saccades could modify them in-flight in response to target movements, even when saccadic suppression of displacement prevented conscious awareness of those movements. Thus saccadic suppression of displacement is not complete, in that it provides perceptual information that is sub-threshold to consciousness but which can still be effectively utilised by the oculomotor system

Assessing the potential economic benefits to farmers from various GM crops becoming available in the European Union by 2025: results from an expert survey
This paper reports on a study that identified a range of crop-trait combinations that are: agronomically suited to the EU; provide advantages to arable farmers and consumers; and are either already available in international markets, or advancing along the development pipeline and likely to become available by 2025. An expert stakeholder panel was recruited and asked for their views, using the Delphi approach, on the impact of these crop-traits on enterprise competitiveness, through changes to yields, production costs and product prices. In terms of input traits, there was consensus that traits such as herbicide tolerant/insect resistant (HT/IR) maize, HT sugar beet and HT soya bean would provide positive benefits for farmers. Output-side traits such as winter-sown rape with reduced saturated fats, were seen as offering benefits to consumers, but were either likely to be restricted to niche markets, or offer relatively modest price premia to farmers growing them. Our analysis of the financial impact of the adoption of GM crops more widely in the EU, showed that the competitiveness of the agricultural sector could well be improved by this. However, such improvements would be relatively small-scale in that large-scale national natural advantages from either economic or environmental conditions is unlikely to be overturned
Control theory for principled heap sizing
We propose a new, principled approach to adaptive heap sizing based on control theory. We review current state-of-the-art heap sizing mechanisms, as deployed in Jikes RVM and HotSpot. We then formulate heap sizing as a control problem, apply and tune a standard controller algorithm, and evaluate its performance on a set of well-known benchmarks. We find our controller adapts the heap size more responsively than existing mechanisms. This responsiveness allows tighter virtual machine memory footprints while preserving target application throughput, which is ideal for both embedded and utility computing domains. In short, we argue that formal, systematic approaches to memory management should be replacing ad-hoc heuristics as the discipline matures. Control-theoretic heap sizing is one such systematic approach
Transformation of National Defense Business Management: Current Initiatives and Future Challenges
The major transformational challenge facing DOD in the period 2005-2008 is how to continue to re-capitalize and modernize the fighting forces while also pushing the pace of business transformation to increase efficiency. This must be accomplished while continuing to pay the high price of waging the war on terrorism. In essence, what DOD must fund and support in the short-term must be traded-off against longer-term investments to improve efficiency and force readiness
Assessment Methods for Comparison of On-Camps and Distance Learning Laboratory Courses in an Engineering Technology Program
Assessment methodology and results for two Electrical Engineering Technology laboratory courses are shown. In these cases, courses are offered in both the traditional on- campus and non-traditional distance learning format, assessment methods are prescribed, assessment data are taken, and the results compiled and compared. Student comments are included which also support the assessment data. In addition, this paper describes ways in which the laboratory courses are structured in order to make the assessment process easier to manage. Pedagogical issues are addressed that were encountered when constructing the distance learning laboratory courses to assure that the learning experience could equal or exceed that of the on- campus counterparts
Brain amyloid in preclinical Alzheimer\u27s disease is associated with increased driving risk
INTRODUCTION: Postmortem studies suggest that fibrillar brain amyloid places people at higher risk for hazardous driving in the preclinical stage of Alzheimer's disease (AD). METHODS: We administered driving questionnaires to 104 older drivers (19 AD, 24 mild cognitive impairment, and 61 cognitive normal) who had a recent (18)F-florbetapir positron emission tomography scan. We examined associations of amyloid standardized uptake value ratios with driving behaviors: traffic violations or accidents in the past 3Ā years. RESULTS: The frequency of violations or accidents was curvilinear with respect to standardized uptake value ratios, peaking around a value of 1.1 (model r(2)Ā =Ā 0.10, PĀ =Ā .002); moreover, this relationship was evident for the cognitively normal participants. DISCUSSION: We found that driving risk is strongly related to accumulating amyloid on positron emission tomography, and that this trend is evident in the preclinical stage of AD. Brain amyloid burden may in part explain the increased crash risk reported in older adults
