Determining a Relationship between Foreign News Media Reports covering U.S. Military Events and Network Incidents against DOD Networks

This thesis explores the nature of the relationship between foreign news media and network incidents against DoD networks. A rank correlation was performed between the number of network incidents against DoD networks and foreign news media reports covering U.S. Military events. Further analysis was conducted to determine the key terms used in the contents of foreign news media reports for the months the reports were significantly correlated with network incidents. Several significant correlations were found between various combinations of regions and categories of network incidents. However, the correlations were only moderate and the key terms only led to a slightly better understanding of such relationships

Diagnostic accuracy of organ electrodermal diagnostics

Objective. To estimate the diagnostic accuracy as well as the scope of utilisation of a new bio-electronic method of organ diagnostics.Design. Double-blind comparative study of the diagnostic results obtained by means of organ electrodermal diagnostics (OED) and clinical diagnoses, as a criterion standard.Setting. Department of Surgery, Helen Joseph Hospital, Johannesburg.Patients. 70 pre-selected inpatients of mean age 36 (SD =7) years with suspected pathology of one (or more) of the following organs: oesophagus, stomach, duodenum, biliary tract, pancreas, colon, kidneys and urinary tract. In total, 276 of the above mentioned internal organs were selected for statistical consideration. Main outcome measures. The difference between the so-called basic electrical impedance of the skin and the impedance value established for a particular organ projection area (the skin zone corresponding to a particular internal organ).Results. In total 250 true OED results were obtained from the 276 subjects considered: detection rate 90.6% (95% Cl 87.1 - 94.1 %). Established OED sensitivity was 91.8% (95% Cl 88.6 - 95.0%) and OED specificity equalled 89.9% (95% Cl 86.4 - 93.4%). The predictive value for positive OED results was 83.3% (95% Cl 78.9 - 87.7%) and for negative OED results 95.2% (95% Cl 92.0 - 98.4%). The OED results were affected neither by the type nor the aetiology of disease, i.e. OED estimates the actual extent of the pathological process within particular organs but does not explain the cause of pathology directly. No sideeffects of the OED examinations were observed.Conclusions. So-called organ projection areas do exist on the skin surface. The electrical impedance of the projection areas corresponding to diseased organs is increased, relative to that of healthy organ-related skin zones. The difference in impedance is proportional to the intensity of the pathological process. OED, which utilises these electrical phenomena of the skin, may detect diseased organs and estimate the extent of pathological process activity within these organs

Weighted decomposition in high-performance lattice-Boltzmann simulations: Are some lattice sites more equal than others?

Obtaining a good load balance is a significant challenge in scaling up lattice-Boltzmann simulations of realistic sparse problems to the exascale. Here we analyze the effect of weighted decomposition on the performance of the HemeLB lattice-Boltzmann simulation environment, when applied to sparse domains. Prior to domain decomposition, we assign wall and in/outlet sites with increased weights which reflect their increased computational cost. We combine our weighted decomposition with a second optimization, which is to sort the lattice sites according to a space filling curve. We tested these strategies on a sparse bifurcation and very sparse aneurysm geometry, and find that using weights reduces calculation load imbalance by up to 85 %, although the overall communication overhead is higher than some of our runs.This work has received funding from the CRESTA and MAPPER projects within the EC-FP7 (ICT-2011.9.13) under Grant Agreements nos. 287703 and 261507, and from EPSRC Grants EP/I017909/1 (www.2020science.net) and EP/I034602/1

Lighten UP! A community-based group intervention to promote psychological well-being in older adults

Objectives: Aging is often characterized by declines in physical and mental health and increased risk for depression and social isolation. A protective factor that has been found to effectively moderate these phenomena is psychological well-being. The aim of his study was to pilot test a novel group intervention (Lighten UP! program) for the promotion of psychological well-being in older adults living in the community. Methods: Lighten UP! is an eight-week program consisting of 90-minute group session designed to teach participants to identify and savor positive experiences across multiple domains of eudaimonic well-being. It was delivered to a sample of 103 men and women aged 60 or over, that were assessed pre- and post-intervention with Ryff's Psychological Well-being Scale (PWB), Life Satisfaction scale, Geriatric Depression Scale, Symptom Questionnaire, and items measuring sleep complaints and social well-being. Results: At the end of the eight weeks, participants reported significantly increased PWB, life satisfaction, and social well-being along with lower levels of depression and fewer physical symptoms and sleep complaints. These gains were particularly robust for individuals with lower pre-program levels of PWB. Conclusions: This pilot investigation suggests the feasibility of a short group program for enhancing well-being in older adults. Future controlled investigations with long-term follow-up assessment are needed to confirm the effectiveness and sustained benefits of the Lighten UP! program. © 2015 Taylor & Franci

Enhanced suppresion of localization in a continuous Random-Dimer Model

We consider a one-dimensional continuous (Kronig-Penney) extension of the (tight-binding) Random Dimer model of Dunlap et al. [Phys. Rev. Lett. 65, 88 (1990)]. We predict that the continuous model has infinitely many resonances (zeroes of the reflection coefficient) giving rise to extended states instead of the one resonance arising in the discrete version. We present exact, transfer-matrix numerical calculations supporting, both realizationwise and on the average, the conclusion that the model has a very large number of extended states.Comment: 10 pages, 3 Figures available on request, REVTeX 3.0, MA/UC3M/1/9

Preparing to work: dramaturgy, cynicism and normative ‘remote’ control in the socialization of graduate recruits in management consulting

online) This paper examines the socialization of graduate recruits into a knowledge intensive labour process and organizational culture. Theoretically the paper draws upon the idea of ‘preparing for work’ to position this early socialization as a crucial moment in the production of subjectivities suited (and booted) for the labour process of management consulting. Empirically the paper reports on a two-day induction session for new graduate recruits joining a global management consultancy and their responses to this training. Particular attention is given to the use of role-play and a dramaturgical workshop used in part of the training process. The paper argues that the utilization of dramaturgy in training is consistent with the overall approach to control developed in the firm in response to the fact that the labour process of consulting is often conducted on client sites, away from any direct supervisory gaze. As such, the consultants were subjected to a form of cultural control that was designed to function independently of direct supervision. This control did not operate directly upon the new employees professed values, however, but at one step removed so that a ‘cynical distance’ from the content of the organization’s culture was accepted so long as a professional ‘ethic of behaviour’ was established. By focusing on an ‘ethic of behaviour’ these young professionals were encouraged to internalize a self-control akin to that of an actor, rather than internalizing the corporate values entirely
