From Gangs of Hooligans to Captains and Generals of the Industrial Army: The Windsor Walkerville Technical School, 1923 - 1973

In contrast to recent general conceptions of technical secondary schools in Ontario the Windsor Walkerville Technical School later named W D Lowe Technical School was wholeheartedly supported by its community The school began with a vision of offering education that was appealing to those boys who were deemed likely to end up in gangs of hooligans The rough and tough reputation of the WWTS WDLTS would attest to the needs that founder F P Gavin saw in the community but the school quickly gained a reputation for turning out the captains and generals of the industrial army in the form of skilled and successful machinists tool and die makers and mould makers who built specialized parts for the automotive industry The school existed historically in a social and economic context with the ingredients for a technical secondary school that served working class male youth well Today those ingredients no longer exis

Perturbations of the Richardson number field by gravity waves

An analytic solution is presented for a stratified fluid of arbitrary constant Richardson number. By computer aided analysis the perturbation fields, including that of the Richardson number can be calculated. The results of the linear analytic model were compared with nonlinear simulations, leading to the following conclusions: (1) the perturbations in the Richardson number field, when small, are produced primarily by the perturbations of the shear; (2) perturbations of in the Richardson number field, even when small, are not symmetric, the increase being significantly larger than the decrease (the linear analytic solution and the nonlinear simulations both confirm this result); (3) as the perturbations grow, this asymmetry increases, but more so in the nonlinear simulations than in the linear analysis; (4) for large perturbations of the shear flow, the static stability, as represented by N2, is the dominating mechanism, becoming zero or negative, and producing convective overturning; and (5) the convectional measure of linearity in lee wave theory, NH/U, is no longer the critical parameter (it is suggested that (H/u sub 0) (du sub 0/dz) takes on this role in a shearing flow)

Heterogeneity in Disordered Gambling: Decision-Making and Impulsivity in Gamblers Grouped by Preferred Form.

Background: Previous research has indicated that disordered gamblers display deficits in impulsivity and risky decision-making, compared to healthy control groups. However, disordered gamblers are not a homogenous group, and differences in performance on neurocognitive tasks may be related to the form of gambling in which an individual chooses to engage. The present study used neurocognitive tasks and questionnaire measures to ascertain group differences in gamblers grouped by preferred form of gambling. Method: Treatment-seeking pathological gamblers from the National Problem Gambling Clinic, London (n = 101), completed a neurocognitive assessment comprising the Cambridge gamble task (CGT), the stop-signal task (SST), a probabilistic reversal learning task (PRL), and the Kirby Monetary Choice Questionnaire, as well as questionnaire measures of gambling severity, impulsivity, depression, and anxiety. Analyses compared gamblers who favored fixed-odds betting terminals (FOBTs) (the modal form) to gamblers who preferred other forms of gambling (non-FOBT). Results: The FOBT group showed impaired decision-making under risk on the CGT compared to the non-FOBT group, choosing the likely option less on more uncertain decisions. The FOBT group made fewer perseverative errors on the PRL task, had lower depression and anxiety scores, and were less likely to have a family history of problem gambling than the non-FOBT group. Discussion: Decision-making and cognitive flexibility differences between gamblers grouped by gambling type supports preferred form as an important source of heterogeneity in gambling disorder. Decision-making strategies and risk attitudes should be considered when approaching cognition-focused treatment strategies, allowing interventions to be targeted at specific cognitive deficits

A Simulation Based Study in a Hospital Emergency Department: Capacity and Workflow Issues

Emergency departments’ capacities to deal with a patient surge (the number of patients increases in a short period of time) play an important role in preparedness for natural or man-made disasters. This paper examines how emergency departments could improve their capacities by optimizing the workflow. A framework is proposed to reconfigure the workflow to improve capacity while maintaining treatment equality. Our results show that reducing lower priority processes and combining originally separate processes can shorten patient total waiting time in the emergency department

Dual effects of ‘losses disguised as wins’ and near-misses in a slot machine game

Individually, both near-misses and losses disguised as wins (LDWs) have been seen to exert pro-motivational effects on gambling. However, it is not clear whether both structural characteristics are effective within the same game. Participants (n = 40) played a slot machine simulation. The simulation delivered near-misses, wins and ‘full-misses’. Half the participants also received LDWs that occurred independently of the outcomes on the payline. Valence and motivation ratings were collected after each round. Results showed that the LDW group reported increased valence ratings compared to the no-LDW group. Within the LDW group, trials with LDWs also resulted in increased enjoyment compared to trials without LDWs. We distinguished near-misses falling either side of the payline. Near-misses before the payline (NMB) were rated as more motivational than near-misses after the payline (NMA), whereas NMAs were rated as more aversive than NMBs. These differences between the two near-miss types were exacerbated by LDWs. Results demonstrate LDWs increase the trial-by-trial enjoyment of non-win outcomes. The motivational and hedonic effects of near-misses differed for events either side of the payline, and these differences were exaggerated by the presence of LDWs. Thus, near-misses can retain their effectiveness in complex forms of gambling that also deliver LDWs

Data Model Development for Fire Related Extreme Events - An Activity Theory and Semiotics Approach

Post analyses of major extreme events reveal that information sharing is critical for an effective emergency response. The lack of consistent data standards in the current emergency management practice however serves only to hinder efficient critical information flow among the incident responders. In this paper, we adopt a theory driven approach to develop a XML-based data model that prescribes a comprehensive set of data standards for fire related extreme events to better address the challenges of information interoperability. The data model development is guided by third generation Activity Theory and semiotics theories for requirement analyses. The model validation is achieved using a RFC-like process typical in standards development. This paper applies the standards to the real case of a fire incident scenario. Further, it complies with the national leading initiatives in emergency standards (National Information Exchange Model)
