- Prolonged sitting, common in many workplaces, reduces blood flow to the lower limb and has negative health outcomes. CoreChair is an active-sitting chair that encourages increased movement to help mitigate these outcomes. Physiological and cognitive measures were recorded in ten participants over four hours of sitting in both the CoreChair and a traditional office chair. Sitting in both chairs led to increases in calf circumference (p

- Management of recreational access on public forest lands is a complex issue of growing global importance. The provision of public recreation opportunities is part of the suite of ecological goods and services that must be considered by many forest managers. Effective access management is predicated on understanding the attitudes and perceptions of recreation users in order to predict and influence visitor behaviour and gauge the acceptance of new management strategies. Potential access management strategies vary given the nature of recreation activities and include: restricting the amount, type, and spatial distribution of use, visitor education, temporal restrictions and enhancing site...

- Videogames are interactive by nature - people proceed in games by doing things, and this experiential quality lies at the very core of game design. Without interaction, it isn’t a game. Videogames are popular precisely because of the experience - games designed for learning can do no less. However, to be feasible for use in formal educational settings, they must do more, and while we are making progress studying games in classrooms, there remain few structured approaches to analysing games that do not include classroom testing. This paper outlines the author’s Four Pillars of Game-Based Learning (4PEG) which can be used to perform a structured analysis of both COTS and serious games to...

- Steady-state tilt has no effect on cerebrovascular reactivity to increases in the partial pressure of end-tidal carbon dioxide (PETCO2). However, the anterior and posterior cerebral circulations may respond differently to a variety of stimuli that alter central blood volume, including lower body negative pressure (LBNP). Little is known about the superimposed effects of head-up tilt (HUT; decreased central blood volume and intracranial pressure) and headdown tilt (HDT; increased central blood volume and intracranial pressure), and LBNP on cerebral blood flow (CBF) responses. We hypothesized that (a) cerebral blood velocity (CBV; an index of CBF) responses during LBNP would not change with...

- Creating a textbook involves ensuring that the content, text, and visual diagrams explain concepts well and as accurately as possible. This includes breaking the text into “bite-sized” palatable chunks that give the students the opportunity to pause, reflect on, and apply what they have learned from each section. The visuals are often just as important as the text; realistic, vibrantly-coloured three-dimensional art is integral for student learning in this subject as it helps to teach the concepts through visualization in addition to theory. The figures must teach well not only on the page, but also when projected on a classroom screen or when viewed on a mobile device. Having a...

- Emerging evidence suggests that ecological heterogeneity across space can influence the genetic structure of populations, including that of long-distance dispersers such as large carnivores. On the central coast of British Columbia, Canada, wolf (Canis lupus L., 1758) dietary niche and parasite prevalence data indicate strong ecological divergence between marine-oriented wolves inhabiting islands and individuals on the coastal mainland that interact primarily with terrestrial prey. Local holders of traditional ecological knowledge, who distinguish between mainland and island wolf forms, also informed our hypothesis that genetic differentiation might occur between wolves from these...

- Migrations of large ungulates are globally threatened in environments affected by increasing human disturbance, rising large carnivore predation, deteriorating habitat quality, and changing climate. Animals migrating outside of protected areas can be exposed to greater human pressure, and this effect can be stronger when humans are perceived to be a predation risk, such as during hunting seasons. Using four consecutive years of satellite telemetry data (n = 138 migration events), we compared habitat selection, movement, and behavior of a large partially migratory herbivore while migrating through a heterogeneous landscape in spring and fall. We tested the hypothesis that fall hunting...

- Across the foot sole, there are vibration and monofilament sensory differences despite an alleged even distribution of cutaneous afferents. Mechanical property differences across foot sole sites have been proposed to account for these differences. Vibration (VPT; 3 Hz, 40 Hz, 250 Hz), and monofilament (MF) perception threshold measurements were compared with skin hardness, epidermal thickness, and stretch response across five foot sole locations in young healthy adults (n = 22). Perceptual thresholds were expected to correlate with all mechanical property measurements to help address sensitivity differences between sites. Following this hypothesis, the MedArch was consistently found to be...

- Delivering fast response times for user transactions is a critical requirement for Web services. Often, a Web service has Service Level Agreements (SLA) with its users that quantify how quickly the service has to respond to a user transaction. Typically, SLAs stipulate requirements for Web service response time percentiles, e.g., a specified target for the 95th percentile of response time. Violating SLAs can have adverse consequences for a Web service operator. Consequently, operators require systematic techniques to predict Web service response time percentiles. Existing prediction techniques are very time consuming since they often involve manual construction of queuing or machine...

- Let X be a real-valued wide sense stationary process over a finite non-abelian group G. We provide results on optimal orthogonal decomposition of X into real-valued mutually orthogonal components and using this decomposition we develop a test for correlation of X over the group G. Applications of these results to the analysis of variance of the carry-over effects in the cross-over designs in clinical studies are given. Our focus will be on groups S[subscript 3], S[subscript 4], and A[subscript 4].

- The Crown of the Continent Ecosystem (CCE) encompasses a 72,000 sq. km area of the Rocky Mountains in southwestern Alberta, southeastern British Columbia, and northwestern Montana. Known for its biodiversity, including a full compliment of mammalian carnivores, managing this ecosystem across many jurisdictional boundaries is challenging. With many stakeholders involved in the Crown of Continent Ecosystem, tracking the research being conducted in this area is essential. This publication includes an annotated bibliography of more than 250 research documents published between between 2000-2015 and makes recommendations as to which areas and topics require further study within the Crown of...

- Many people struggle with the fundamental concepts underlying Mendelian genetics. As soon as we involve more than two traits things get complicated. The classic examples are fine, but additional resources can be helpful. Besides, playing with blood isn't all it's cracked up to be, and rabbits are cuter. Here's a visual way to learn the jargon and the basic principles of Mendelian inheritance while playing a fast-paced card game using rabbit coat color genetics. Coat color in rabbits demonstrates dominance/recessive traits, differences in pheno- vs genotypes, epistatis, and multiple alleles - all of which blend together to form the color we see. Gene Rummy is a variation of Gin Rummy....

- The cerebellum is implicated in the pathophysiology of numerous movement disorders, which makes it an attractive target for noninvasive neurostimulation. Continuous theta burst stimulation (cTBS) can induce long lasting plastic changes in human brain; however, the efficacy of different simulation protocols has not been investigated at the cerebellum. Here, we compare a traditional 50-Hz and a modified 30-Hz cTBS protocols at modulating cerebellar activity in healthy subjects. Seventeen healthy adults participated in two testing sessions where they received either 50-Hz (cTBS50) or 30-Hz (cTBS30) cerebellar cTBS. Cerebellar brain inhibition (CBI), a measure of cerebello-thalamocortical...

- Neurovascular coupling (NVC) is the temporal link between neuronal metabolic activity and regional cerebral blood flow (CBF), supporting adequate delivery of nutrients. Exposure to high altitude (HA) imposes several stressors, including hypoxia and hypocapnia, which modulate cerebrovascular tone in an antagonistic fashion. Whether these contrasting stressors and subsequent adaptations affect NVC during incremental ascent to HA is unclear. The aim of this study was to assess whether incremental ascent to HA influences the NVC response. Given that CBF is sensitive to changes in arterial blood gasses, in particular PaCO2, we hypothesized that the vasoconstrictive effect of hypocapnia during...

- Before researchers can perform studies using commercial games, they must choose which game or games to study. The manner in which that choice is made and justified is the focus of this paper. Ideally, research informs pedagogy and when looking at game education it is important to be able to justify and defend conclusions drawn from game studies so they can inform best practices in design and development. As the number and sophistication of titles released in a given year continues to rise, it becomes even more important to look more seriously at how we are choosing the games we study, the criteria we use for those studies, how we support our claims about the suitability of the game for...
