- Abstract
- Presented at the Pathways to Prosperity National Conference - Shaping Immigration to Canada: Learning from the Past and a Vision for the Future, 2018, Ottawa, Ontario. In the second workshop, "Public Perceptions of Refugees: Contexts and Response": While Canada’s overall commitment to resettling refugees is admirable, there are those within Canadian society who view such arrivals with apprehension. When politicians, pundits, media, and the broader public express disparaging views or opinions about refugees, the result, whether intentional or not, is the reinforcing of negative prejudices and stereotypes. The goal of this session is to assess the opinions and views of the broader public and media towards refugees while examining the impact that such perspectives may have on refugees in Canada.

- Confronting two-tiered community recreation and poor women's exclusion: Promoting inclusion, health and social justice

- Abstract
- The social, psychological, and physical health benefits of participation in physical activity and other forms of recreation are well documented (Frankish, Milligan and Reid; Sallis and Owen; Reid and Dyck), and evidence suggests that low-income women view access to community recreation as an important dimension of their health and their communities (Weber; Frisby and Hoeber). Although many community recreation departments in Canada have a social mandate of providing services to all citizens to promote health and well being, consistent barriers to regular involvement persist for those who live on the margins and are unable to conform to dominant expectations inherent in modern forms of public recreation (Frisby, Crawford and Dorer; Lyons and Langille;Harvey). With its individualist ideology, classist notions of self-responsibility, and fees for service, we argue that community recreation has become a two-tiered system where only those with sufficient social, cultural, and financial resources can participate (Kidd). Consequently, insufficient subsidies, policies requiring "proof of poverty," and discrimina- tory practices exclude poor women from being actively involved in health-promoting forms of community recreation. The purposes of this paper are: i) to examine how low-income women see involvement in community recreation contributing to their health, and ii) to examine low-income women's experiences with exclusionary community recreation policies and practices. Hearing the voices of those who are marginalized from the knowledge production and policy development process is important when considering how public sector programs, policies, and practices can become more inclusive (Lord and Hutchison; Frisby and Hoeber). Through fostering inclusion rather than classist forms of service delivery, the community development and social justice mandates of many community recreation departments is advanced thus providing health-promoting resources for those living on the margins.

- Abstract
- The extent to which critical pedagogy disrupts the relations of dominance inside postsecondary classrooms, or empowers students to take socially just action beyond the classroom has been debated and challenged for decades. Through the use of métissage, an interpretive inquiry method that affords collaborative interrogation of individual autoethnographic writings, we five participants in the same critical pedagogy course conducted a post-course inquiry project in order to explore what we had learned through the course. Through this inquiry project, we have come to a deeper understanding of critical pedagogy praxis. Ultimately, what we learned through the use of this inquiry method maintains important implications for postsecondary educators.

- Abstract
- Although integrating progress monitoring (PM) measures into psychotherapy practice can provide numerous benefits, including improved client outcomes, relatively few clinicians use these measures (e.g., Ionita & Fitzpatrick, 2014). To better understand the reasons for clinicians’ reluctance, consensual qualitative research methodology was used to examine the challenges faced by clinicians currently using PM measures. Open-ended, semistructured interviews, with 25 clinicians who chose to use PM measures, revealed that clinicians tended to face challenges involving technical concerns, negative responses from others, and personal barriers such as anxiety. The majority of participants discussed ways to overcome the challenges they experienced, including ensuring the fit of the PM measure, explaining measures to others to help engender a positive response, adapting their own perspective, and increasing their own and others’ knowledge of the measures. Implications for practicing psychologists and for knowledge translation efforts are discussed.

- Abstract
- Long-term potentiation (LTP) is a sustained increase in the efficacy of synaptic transmission, based on functional changes involving pre- and postsynaptic mechanisms, and has been considered a cellular model for learning and memory. The sulphurated tripeptide glutathione acts as a powerful antioxidant agent within the nervous system. Recent in vitro studies suggest that the cellular redox status might influence the mechanisms involved in synaptic plasticity. It is not known, however, how glutathione depletion might affect LTP. In the present study, we evaluated the input-output relationships, LTP, and paired-pulse interactions in rats with low glutathione levels induced by systemic injection of diethylmaleate. Our results in anesthetized rats show that the basic synaptic transmission between the perforant pathway and the dentate gyrus granule cells was not affected by glutathione depletion. However, in the same synapses it was not possible to induce prolonged changes in synaptic efficacy (LTP). Paired-pulse facilitation was also absent in the treated animals, suggesting an impairment of short-term synaptic interactions. These findings indicate that low content of glutathione can impair short-term and long-term mechanisms of synaptic plasticity and stress the importance of the redox balance in the normal function of brain circuitry.

- Abstract
- Several imprinted genes have been implicated in the regulation of placental function and embryonic growth. On distal mouse chromosome 7, two clusters of imprinted genes, each regulated by its own imprinting center (IC), are separated by a poorly characterized region of 280 kb (the IC1–IC2 interval). We previously generated a mouse line in which this IC1–IC2 interval has been deleted (Del7AI allele) and found that maternal inheritance of this allele results in low birth weights in newborns. Here we report that Del7AI causes a partial loss of Ascl2, a maternally expressed gene in the IC2 cluster, which when knocked out leads to embryonic lethality at midgestation due to a lack of spongiotrophoblast formation. The hypomorphic Ascl2 allele causes embryonic growth restriction and an associated placental phenotype characterized by a reduction in placental weight, reduced spongiotrophoblast population, absence of glycogen cells, and an expanded trophoblast giant cell layer. We also uncovered severe defects in the labyrinth layer of maternal mutants including increased production of the trilaminar labyrinth trophoblast cell types and a disorganized labyrinthine vasculature. Our results have important implications for our understanding of the role played by the spongiotrophoblast layer during placentation and show that regulation of the dosage of the imprinted gene Ascl2 can affect all three layers of the chorio-allantoic placenta.

- Abstract
- The coastal old-growth forests of North America’s Pacific Coast are renowned both for their commercial and ecological value. This study adds to growing evidence that selective harvesting of the largest trees may have a disproportionate ecological impact. Marbled Murrelets (Brachyramphus marmoratus), a threatened species, nest almost exclusively in these old-growth forests. Detailed knowledge of nesting habitat selection provides guidance for habitat management and conservation. Habitat selection for this species has been studied at a variety of scales using ground and remote methods. However, because Marbled Murrelet nesting activity is limited to a single mossy platform on a single tree, we investigated nest tree selection within old-growth forest patches, using a set of 59 forest patches containing active nests. Nest trees were usually distinctive compared with neighboring trees in the surrounding 25 m radius patch. They averaged 15 to 20% taller than neighboring trees depending on region, had significantly larger stem diameters, more potential nesting platforms, and more moss. They had the most extreme values of height and width about three times as often as expected by chance. An analysis of moss platform use as a function of number of platforms per platform tree suggests that murrelets select individual platforms, rather than platform trees per se. Nonetheless, highly selective logging practices that remove high-value trees from stands may also remove trees most likely to be selected by nesting murrelets.

- Abstract
- The purpose of this paper is to examine the existing risks for the offshore project and risk weighting using the fuzzy best worst method (FBWM). In offshore oil projects, we face six major risks. Each of these risks is divided into smaller risks leaving us to have a total of 34 risks. Some of these risks are internal and some are external risks. In this method, first, the experts of this field determined the best and the worst type of risk. Then, using the experts’ opinions, the study compared the remaining risks with the two selected risks and the other weights are determined. In our survey, “Technical Risk and Project Execution” is the most important risk factor followed by “Political Risk and Sanctions”, “Market risk”, “Management risk”, “Financial risk and currency fluctuations” and “Environmental risk”.

- The physiology of rock climbing

- Abstract
- In general, elite climbers have been characterised as small in stature, with low percentage body fat and body mass. Currently, there are mixed conclusions surrounding body mass and composition, potentially because of variable subject ability, method of assessment and calculation. Muscular strength and endurance in rock climbers have been primarily measured on the forearm, hand and fingers via dynamometry. When absolute hand strength was assessed, there was little difference between climbers and the general population. When expressed in relation to body mass, elite-level climbers scored significantly higher, highlighting the potential importance of low body mass. Rock climbing is characterised by repeated bouts of isometric contractions. Hand grip endurance has been measured by both repeated isometric contractions and sustained contractions, at a percentage of maximum voluntary contraction. Exercise times to fatigue during repeated isometric contractions have been found to be significantly better in climbers when compared with sedentary individuals. However, during sustained contractions until exhaustion, climbers did not differ from the normal population, emphasising the importance of the ability to perform repeated isometric forearm contractions without fatigue becoming detrimental to performance. A decrease in handgrip strength and endurance has been related to an increase in blood lactate, with lactate levels increasing with the angle of climbing. Active recovery has been shown to provide a better rate of recovery and allows the body to return to its pre-exercised state quicker. It could be suggested that an increased ability to tolerate and remove lactic acid during climbing may be beneficial. Because of increased demand placed upon the upper body during climbing of increased difficulty, possessing greater strength and endurance in the arms and shoulders could be advantageous. Flexibility has not been identified as a necessary determinant of climbing success, although climbing-specific flexibility could be valuable to climbing performance. As the difficulty of climbing increases, so does oxygen uptake (V̇O2), energy expenditure and heart rate per metre of climb, with a disproportionate rise in heart rate compared with V̇O2. It was suggested that these may be due to a metaboreflex causing a sympathetically mediated pressor response. In addition, climbers had an attenuated blood pressure response to isometric handgrip exercises when compared with non-climbers, potentially because of reduced metabolite build-up causing less stimulation of the muscle metaboreflex. Training has been emphasised as an important component in climbing success, although there is little literature reviewing the influence of specific training components upon climbing performance. In summary, it appears that success in climbing is not related to individual physiological variables but is the result of a complex interaction of physiological and psychological factors.

- The influence of oviposition experience on response to host pheromone in Trichogramma sibericum (Hymenoptera: Trichogrammatidae)

- Abstract
- Searching times and residence times of Trichogramma sibericum Sorokina were measured in the laboratory on individual cranberry leaves that had been treated with the sex pheromone of blackheaded fireworm [Rhopobota naevana (Hübner)] and on leaves that were left untreated. Mean searching time was higher on leaves treated by passive diffusion with either 50 or 100 μg of the main component of fireworm pheromone, (Z)-11-tetradecen-1-ol acetate (Z11-14: Ac), than on control leaves. Mean residence times were also higher on leaves treated by passive diffusion with 50 μg of Z11-14: Ac than on leaves untreated with pheromone. Pretrial oviposition experience in either the presence or the absence of host pheromone did not influence variation in searching time or residence time. This indicates that neither associative learning of the odor of host pheromone nor a more generalized increase in response to chemical stimuli after oviposition (priming) affects retention responses of T. sibericum to pheromone. Results are discussed in the context of current theories on the evolution of learning in insect parasitoids and as they relate to the concurrent use of pheromone-based mating disruption and releases of T. sibericum for pest management of the blackheaded fireworm.

- Barefoot running: Minimal shoes for minimal injury?

- Abstract
- Running features repetitive, impactful movements resulting in 79% of runners getting injured each year (Altman & Davis, 2012). Ground reaction forces while running can reach between 2.5-2.8 times a person’s body weight and must be dissipated properly to prevent injury (Cavanagh & LaFortune, 1980). Rearfoot strikers generate a higher impact peak in comparison to forefoot strikers (Daoud et al, 2012). Running with shorter stride lengths can also reduce the peak vertical ground reaction force (Heiderscheit, Chumanov, Michalski, Wille, & Ryan, 2011). It is hypothesized that runners who are barefoot will run with shorter strides and a mid or forefoot strike pattern thus reducing the ground reaction force that must be absorbed by the limbs of the runner (Liebermen et al, 2010).

- The time lag between a carbon dioxide emission and maximum warming increases with the size of the emission

- Abstract
- In a recent letter, Ricke and Caldeira (2014 Environ. Res. Lett. 9 124002) estimated that the timing between an emission and the maximum temperature response is a decade on average. In their analysis, they took into account uncertainties about the carbon cycle, the rate of ocean heat uptake and the climate sensitivity but did not consider one important uncertainty: the size of the emission. Using simulations with an Earth System Model we show that the time lag between a carbon dioxide (CO2) emission pulse and the maximum warming increases for larger pulses. Our results suggest that as CO2 accumulates in the atmosphere, the full warming effect of an emission may not be felt for several decades, if not centuries. Most of the warming, however, will emerge relatively quickly, implying that CO2 emission cuts will not only benefit subsequent generations but also the generation implementing those cuts.

- Abstract
- Fetal alcohol spectrum disorder (FASD) is increasingly recognized as a growing public health issue worldwide. Although more research is needed on both the diagnosis and treatment of FASD, and a broader and more culturally diverse range of services are needed to support those who suffer from FASD and their families, both research and practice for FASD raise significant ethical issues. In response, from the point of view of both research and clinical neuroethics, we provide a framework that emphasizes the need to maximize benefits and minimize harm, promote justice, and foster respect for persons within a global context.

- Maintenance of EMG activity and loss of force output with instability
- Author(s)

- Abstract
- Swiss Balls used as a platform for training provide an unstable environment for force production. The objective of this study was to measure differences in force output and electromyographic (EMG) activity of the pectoralis major, anterior deltoid, triceps, latissimus dorsi, and rectus abdominus for isometric and dynamic contractions under stable and unstable conditions. Ten healthy male subjects performed a chest press while supported on a bench or a ball. Unstable isometric maximum force output was 59.6% less than under stable conditions. However, there were no significant differences in overall EMG activity between the stable and unstable protocols. Greater EMG activity was detected with concentric vs. eccentric or isometric contractions. The decreased balance associated with resistance training on an unstable surface may force limb musculature to play a greater role in joint stability. The diminished force output suggests that the overload stresses required for strength training necessitate the inclusion of resistance training on stable surfaces. ABSTRACT FROM AUTHOR

- Abstract
- The ultramafic (serpentine) outcrops of Cuba represent the 7% of Cuban surface and are the largest one of the Caribbean region. Ultramafic soils usually have low levels of nutrients, and toxic levels of Mg and heavy metals. In this paper, we characterize the flora of the Guamuhaya ultramafic region and analyze its possible origin and phytogeographical relationships. This region contains 233 species, 55 of them are Cuban endemism and one (Rondeletia bicolor) is restricted to this region. This flora is mostly composed by Antillean, Neotropical and Central-west Cuban species.

- Abstract
- This study compared the effects of a social story-only intervention with the effects of a social story-plus practices session intervention as implemented with preschool age children with disabilities (n = 16) and without disabilities (n = 16) in an inclusive preschool setting. The social story interventions were implemented with groups of four children in order to examine the impact of the intervention on the children's prosocial and antisocial skills. The findings of the study differ from previous research in that the social story interventions were not found to be an effective intervention. The significance of these findings, limitations of the study, and future research suggestions are discussed.
