The University of Winnipeg is a public university in Winnipeg, Manitoba, Canada that offers undergraduate faculties of art, business and economics, education, science and kinesiology and applied health as well as graduate programs. UWinnipeg's founding colleges were Manitoba College and Wesley College, which merged to form United College in 1938. The University of Winnipeg was established in 1967 when United College received its charter. The governance was modeled on the provincial University of Toronto Act of 1906 which established a bicameral system of university government consisting of a senate , responsible for academic policy, and a board of governors exercising exclusive control over financial policy and having formal authority in all other matters. The president, appointed by the board, was a link between the bodies to perform institutional leadership.UWinnipeg's current President and Vice-Chancellor is Dr. Annette Trimbee , succeeding Dr. Lloyd Axworthy who served from 2004 to 2014.Maclean's magazine and the Globe and Mail newspaper consistently rank the university in the top fifteen of all Canadian universities whose primary focus is undergraduate education in the category of student satisfaction. In 2013 the U of W ranked 13th out of 19 primarily undergraduate institutions.The U of W was the first university in Canada to ban the sale of plastic bottled water on campus. Wikipedia.

A new report from social psychologists at the University of Illinois at Chicago and the University of Winnipeg suggests people on both sides of the political aisle are similarly motivated to dismiss monetary enticements in order to distance themselves from hearing or reading opposing ideals and information. The research, published online by the Journal of Experimental Social Psychology, details the findings from five studies involving liberals and conservatives who were presented with statements on issues such as same-sex marriage, U.S. and Canada elections, marijuana, climate change, guns and abortion. Approximately two-thirds of respondents declined a chance to win extra money in order to avoid reading statements that didn't support their position, say report co-authors Linda Skitka, UIC professor of psychology, and Matt Motyl, UIC assistant professor of psychology. The UIC researchers and Jeremy A. Frimer, a corresponding author from the University of Winnipeg, indicate the divide goes beyond political topics. Respondents also had a "greater desire to hear from like- versus unlike-minded others on questions such as preferred beverages (Coke vs. Pepsi), seasons (spring vs. autumn), airplane seats (aisle vs. window), and sports leagues (NFL vs. NBA)," they wrote. The aversion to hearing or learning about the views of their ideological opponents is not a product of people already being or feeling knowledgeable, or attributable to election fatigue in the case of political issues, according to the researchers. "Rather, people on both sides indicated that they anticipated that hearing from the other side would induce cognitive dissonance," such that would require effort or cause frustration, and "undermine a sense of shared reality with the person expressing disparate views" that would harm relationships, they reported. The researchers note the drawback of liberals and conservatives retreating to ideological information bubbles. "What could ultimately be a contest of ideas is being replaced by two, non-interacting monopolies," they said. The report was supported by a grant from the Social Sciences and Humanities Research Council of Canada.

It is a fundamental property of non-letter Lyndon words that they can be expressed as a concatenation of two shorter Lyndon words. This leads to a naive lower bound ⌈log2(n)⌉ + 1 for the number of distinct Lyndon factors that a Lyndon word of length n must have, but this bound is not optimal. In this paper we show that a much more accurate lower bound is ⌈logφ(n)⌉ + 1, where φ denotes the golden ratio (1+5)/2. We show that this bound is optimal in that it is attained by the Fibonacci Lyndon words. We then introduce a mapping Lx that counts the number of Lyndon factors of length at most n in an infinite word x. We show that a recurrent infinite word x is aperiodic if and only if Lx≥Lf, where f is the Fibonacci infinite word, with equality if and only if x is in the shift orbit closure of f. © 2013 Elsevier Inc.

White-nose syndrome (WNS) is a mysterious condition affecting populations of hibernating bats in the northeastern US. Little is known about its physiological effects on bats and no intervention has so far been proposed to slow associated mortality. We use an individual-based population model to examine how disruption of normal hibernation or pre-hibernation physiology could lead to the pattern of mortality that has been observed. We present evidence that artificial warming of localized areas within hibernacula could increase survival of WNS-affected bats during winter by lessening the energetic costs of periodic arousals. The model suggests that localized thermal refugia of 28°C could improve survival by up to 75%, depending on how WNS acts to disrupt energy balance. This approach has yet to be tested, but it could serve as a stopgap measure to slow population declines until a solution is found, or to preserve remnant bat populations if WNS becomes ubiquitous throughout the ranges of affected species. © The Ecological Society of America.

Abstract In the last decade, sustainable supply chain management has become a key topic in the sustainability literature as well as a buzzword in industry and policy circles. Although research has made substantial contributions, there is a lack of understanding on how focal companies operating in emerging economies can lead the implementation of sustainability into their supply chains. This research connects and advances the constructs of cleaner production, sustainability and supply chains by exploring a classic case of a focal company operating in an emerging economy that, even facing considerable challenges, has been able to succeed in transforming its entire supply chain. Drawing from stakeholder theory and contingency theory, this research offers four key contributions to the sustainability and supply chain discourses as follows: 1) it proposes an innovation-centered approach to sustainable supply chain management, by adapting and extending the TCOS uncertainty framework; 2) it suggests that the way a focal company manages and is influenced by its established network of relationships shape the evolution of the supply chain sustainability trajectories; 3) it argues that supply chains are dynamic entities and should then be considered and understood through the lenses of evolutionary approaches; and 4) it suggests that the implementation and management of sustainable supply chains are context-specific challenges and therefore theoretical, managerial and policy generalizations are difficult to be achieved. © 2014 Elsevier Ltd.

Siblings within the same family often differ dramatically in phenotype. Some differences are attributable to initial maternal handicaps (birth or hatching asynchrony, differences in egg or neonate size and hormonal or antioxidant titre); but differences among siblings may also arise from differences in the brood-rearing environment that offspring experience. Here, I use a model system-a long-term study of nestlings in an altricial bird-to study how an initial maternal handicap, hatching asynchrony, regulates the effective social environment of siblings in the same family as measured by offspring survival. The interaction of family size and structure generated wide differences in the effective environments of siblings living in the same physical space (a nest), and reared by the same parents, in the same family structure. Social rank was the key component of the unshared environment of contemporary siblings, and was alone sufficient to generate near-maximal differences in offspring performance. Nestlings sitting side-by-side effectively lived in different worlds. © 2010 The Royal Society.

We examined the effect of regional climate warming on the phenology of butterfly species in boreal forest ecosystems in Manitoba, Canada. For the period 1971-2004, the mean monthly temperatures in January, September, and December increased significantly, as did the mean temperatures for several concurrent monthly periods. The mean annual temperature increased ≈ 0.05°C/yr over the study period. The annual number of frost-free days and degree-day accumulations increased as well. We measured the response of 19 common butterfly species to these temperature changes with the date of first appearance, week of peak abundance, and the length of flight period over the 33-yr period of 1972-2004. Although adult butterfly response was variable for spring and summer months, 13 of 19 species showed a significant (P < 0.05) increase in flight period extending longer into the autumn. Flight period extensions increased by 31.5 ± 13.9 (SD) d over the study period for 13 butterfly species significantly affected by the warming trend. The early autumn and winter months warmed significantly, and butterflies seem to be responding to this warming trend with a change in the length of certain life stages. Two species, Junonia coenia and Euphydryas phaeton, increased their northerly ranges by ≈ 150 and 70 km, respectively. Warmer autumns and winters may be providing opportunities for range extensions of more southerly butterfly species held at bay by past climatic conditions.

In avian families, some offspring are rendered unequal by parental fiat. By imposing phenotypic handicaps (e. g., via asynchronous hatching) upon certain of their offspring and not others, parents structure the sibship into castes of advantaged "core" offspring and disadvantaged "marginal" offspring that results in an asymmetric sibling rivalry. Here, I show how this family structure scales up to population level reproductive consequences. In a 17-year study of red-winged blackbirds (Agelaius phoeniceus), I show that year-to-year variation in the number of surviving offspring is driven primarily by variation in the number of marginal offspring at hatching and their posthatching survival. Clutch size, core brood at hatching, and fledging varied little from year to year and had little direct effect on year-to-year variation in total brood size at fledging; conversely, variation in the size of the marginal brood at hatching and at fledging was much greater. Marginal but not core brood size at hatching rose with mean clutch size; in years where parents laid larger average clutches they did so by adding marginal progeny. The mean posthatching survival of marginal offspring was always lower than that of core offspring in a given year, and there was no overlap in the distributions. The highest mean survival of marginal offspring across years fell below the lowest mean survival of core offspring; broods were deeply structured. There was an overall female bias among fledglings, and the sex ratio varied across years, with a higher proportion of the smaller female nestlings in years of below average reproductive success. Such variation was especially pronounced in the marginal brood where a higher incidence of brood reduction allowed greater potential for sex-biased nestling mortality. In years of the highest average reproductive success, the sex ratio in the marginal brood approached equality, whereas in years of the lowest average reproductive success, more than two thirds of 8-day-old nestlings were female. Structuring the brood into core and marginal elements allowed parents to modulate both offspring number and sex under ecological uncertainty with direct consequences for population-level reproductive success. They produced fewer and less expensive fledglings in below average years and more and more expensive fledglings in above average years. © Springer-Verlag 2009.

Hints of direct dark matter detection coming from the DAMA, CoGeNT experiments point toward light dark matter with isospin-violating and possibly inelastic couplings. However an array of astrophysical constraints are rapidly closing the window on light dark matter. We point out that if the relic density is determined by annihilation into invisible states, these constraints can be evaded. As an example we present a model of quasi-Dirac dark matter, interacting via two U(1) gauge bosons, one of which couples to baryon number and the other which kinetically mixes with the photon. Annihilation is primarily into "dark neutrinos" that do not mix with the SM, but which could provide an extra component of dark radiation. The model could soon be tested by several experiments searching for such light gauge bosons, and we predict that both could be detected. The model also requires a fourth generation of quarks, whose existence might increase the production cross section of Higgs bosons at the Tevatron and LHC. © 2011 Elsevier B.V.

We consider a newsvendor problem in a supply chain that consists of a manufacturer and a retailer. The manufacturer is the Stackelberg leader and the retailer is the follower. We examine how the manufacturer can contract a wholesale-price-only agreement with its retailer that maximizes its profit. We also propose a returns policy with a wholesale-price-discount scheme (returns-discount contract) that can achieve supply chain coordination. Using the wholesale price only contract as a benchmark, we show how the manufacturer sets a discounted wholesale price in a returns-discount contract that enhances both profits of the manufacturer and the retailer, as well as improves the supply chain efficiency. © 2010 Elsevier B.V.

Factor retrieving is a major approach for pulse wave analysis. Stiffness index and cardiac output are widely used factors for cardiac risk detection. Research has been done on clinical pulse wave data which are collected by pulse oximeter. The result shows that collected factors have a positive correlation with certain cardiac risks. Some adjustments have been applied on the algorithms that increase the significance. In addition to the factor based analysis, other signal processing techniques for pulse waveforms are included such as bispectrum estimation, Wavelet transform, and weighted dynamic time warping. Bispectrum estimation and Wavelet transform have meaningful features of pulse waveforms with some special shapes. Weighted dynamic time warping compares the similarity of waveforms. It also includes medical significance into the calculation by adjusting the weight vector. This algorithm has higher accuracy when providing more samples to compare. The factor based analysis and waveform analysis compose an analytic model which can be used for risk evaluation, classification and disease detection.
