The number of interruptions people experience on a daily basis has grown considerably over the last decade and this growth has not shown any signs of subsiding. In fact, with the In this work, an architecture for a cloud-based interruption management system for mobile device users is presented. The system draws from rich contextual information from the mobile device (i.e., user, task and environment dimensions) and real-time observations of the user's activities and then reasons about ideal times to interact with the user. The reasoning component (interruption algorithm) is situated in the cloud and implemented using a novel machine learning technique (an Adaptive Neuro Fuzzy Inference System). This research addresses the complex problem of determining the precise time to interact with a mobile device user and in so doing aims to reduce the negative aspects of interruptions. This paper also presents a new interruption taxonomy built on an existing framework, and a report on the current prototype developed. © 2014 Elsevier B.V. Source

Spinal cord injury (SCI) is a devastating condition that currently lacks clinically-relevant and effective neuroprotective therapeutic options. Optimal therapeutic agents for clinical translation should show efficacy in a cervical compression/contusion model using a clinically-relevant post-injury therapeutic time window. To date, few compounds have met that rigorous standard. The objective of this work was to evaluate the efficacy of delayed post-injury administration of soluble Fas receptor (sFasR) via intrathecal catheter following acute cervical SCI in a clinically-relevant contusion/compression model. Female Wistar rats were given a C7-T1 moderately severe clip compression injury, followed by either 8-h or 24-h delayed treatment initiation. Long-term neurobehavioral analysis of motor recovery and neuropathic pain development was undertaken. The extent of oligodendrocyte and neuron survival was assessed in peri-lesional cord sections 8 weeks post-SCI. This was complemented by an evaluation of the level of tissue preservation at and adjacent to the site of injury. In animals treated with sFasR delayed 8 h post-injury, significant behavioral effects were observed, coinciding with enhanced cell survival, peri-lesional tissue sparing, and enhanced integrity of descending fiber tracts compared to control treatments. Animals treated with sFasR delayed by 24 h showed more modest improvements in behavioral recovery, and had consistent improvements in cell survival and tissue preservation. This work has shown for the first time that the Fas-mediated apoptotic pathway can be therapeutically targeted in a clinically-relevant time window post-SCI. © Mary Ann Liebert, Inc. 2012. Source

Objective: In 2005, the Ontario Ministry of Education announced a policy requiring that all elementary students be provided with opportunities to participate in a minimum of 20 minutes of sustained moderate-to-vigorous physical activity (MVPA) each school day during instructional time. To the authors' knowledge, this policy has never been formally evaluated. In a form of natural experiment with Project BEAT, we explored within 16 Toronto District School Board schools the proportion of children who participate in DPA, and the proportion who achieve sustained MVPA within these sessions; these are the objectives of this article. Methods: Consent was given by 1,027 parents/guardians for their children to participate (boys, n=478; girls, n=549). Physical activity (PA) was measured using accelerometry and classroom schedules collected to identify sessions of DPA. The frequency of DPA and number and duration of sustained bouts of MVPA (≥5 min) were computed and explored relative to PA levels and health outcomes. Results: Fewer than half of the participating children were provided with DPA every day and not a single child engaged in sustained MVPA for≥20 minutes. On the more positive side, children who engaged in DPA every day were significantly more active than their peers. Those accumulating at least 1 bout of MVPA were more active and likely to meet PA guidelines, and fewer of these children were overweight. Conclusion: The majority of schools are not meeting the DPA policy. However, as the frequency and intensity of DPA increases, so do positive health outcomes. This paper provides supporting evidence that when this policy is implemented, the intended health benefits are achievable. © Canadian Public Health Association, 2012. All rights reserved. Source

This paper presents a method for hand gesture recognition to control a 6 axis industrial robot. The image is acquired by means of a web cam system, and undergoes several processing stages before a meaningful recognition can be achieved. Some of these stages include skin detection to effectively capture only the skin region of the hand, noise elimination, application of the convex hull algorithm to get the outline of the hand, and apply convexity hull defects algorithm to determine the finger count. Once the finger count has been determined, the information is transmitted via serial communication to the industrial robot controller. The end effector of the robot moves in four different directions based on the finger count input received from the hand gesture recognition module. © 2013 IEEE. Source

Colleges offering 2-year diplomas to high-school graduates were among the forefront leaders in online learning however studies illustrating appropriate course construction for such student populations are scarce. Pharmacy Math (MATH16532) is a core course for students enrolled in the Practical Nursing (PN) and Pharmacy Technician (PT) programs at Sheridan Institute. PT and PN students enrolled in MATH16532 during their first term were surveyed to determine student attitudes and skills gained from participating in an online course. Students were then followed up during their second term studies to determine transferability of skills gained. Initially, students did not exhibit a positive attitude towards the online version of Math16532. Participation in the online version of MATH16532 however allowed students to enhance their written ability and critical appraisal skills, gain time management skills, and become independent learners. PT and PN students preferred an orientation session at the beginning of the course and a well organized, easy-to-navigate course. Even though considered as predominantly digital native students, both student groups remained anxious throughout the course regarding the online delivery and preferred a hybrid mode of delivery. Despite the initial resistance to an online math course, students indicated that they would retake the course again in an online format towards the end of the course and there appeared to be a trend to enrol in another online course. Several recommendations regarding the design and construct of online courses in a 2-year college program are provided to facilitate acceptance of online learning for students enrolled in such programs. © 2012 Elsevier Ltd.
