Concordia University is a Canadian public comprehensive university with campuses and facilities in Montreal, Quebec, Canada.Founded in 1974 following the merger of Loyola College and Sir George Williams University, Concordia is one of the two universities in Montreal where English is the primary language of instruction. As of the 2011-2012 academic year, there were 45,954 students enrolled at Concordia, making the university among the largest in Canada by enrollment. The university has two campuses, set approximately seven km apart: Sir George Williams Campus in the downtown core of Montreal, in an area known as Quartier Concordia and Loyola Campus in the residential district of Notre-Dame-de-Grâce. With four faculties, a school of graduate studies and numerous colleges, centres and institutes, Concordia offers over 300 undergraduate and 100 graduate programs and courses.Concordia was ranked 7th among Canadian and 229th among world universities in the International Professional Classification of Higher Education Institutions, a worldwide ranking compiled by the École des Mines de Paris that uses as its sole criterion the number of graduates occupying the rank of Chief Executive Officer at Fortune 500 companies. The university was ranked 11th among Canada's comprehensive universities in the Maclean's 24th annual rankings. Internationally, Concordia was ranked 461-470th overall in the 2014 QS World University Rankings. Nationally, the 2012 Higher Education Strategy Associates' University Rankings placed Concordia 9th in the field of social science and 20th in science and engineering. The university's John Molson School of Business is consistently ranked within the top ten Canadian business schools, and within the top 100 worldwide.Concordia is a non-sectarian and coeducational institution, with over 175,000 living alumni worldwide.The University is a member of the Association of Universities and Colleges of Canada, the International Association of Universities, the Association of Commonwealth Universities, the Canadian Association of Research Libraries, the Canadian University Society for Intercollegiate Debate as well as the Canadian Bureau for International Education and the Canadian University Press. The university's varsity teams, known as the Stingers, compete in the Quebec Student Sport Federation of Canadian Interuniversity Sport. Wikipedia.

Presenteeism is attending work when ill. This study examined the antecedents and correlates of presenteeism, absenteeism, and productivity loss attributed to presenteeism. Predictors included work context, personal characteristics, and work experiences. Business school graduates employed in a variety of work positions (N = 444) completed a Web-based survey. Presenteeism was positively associated with task significance, task interdependence, ease of replacement, and work to family conflict and negatively associated with neuroticism, equity, job security, internal health locus of control, and the perceived legitimacy of absence. Absenteeism was positively related to task significance, perceived absence legitimacy, and family to work conflict and negatively related to task interdependence and work to family conflict. Those high on neuroticism, the unconscientious, the job-insecure, those who viewed absence as more legitimate, and those experiencing work-family conflict reported more productivity loss. Overall, the results reveal the value of a behavioral approach to presenteeism over and above a strict medical model. © 2011 American Psychological Association. Source

Polylactide (PLA) and its copolymers are one type of hydrophobic aliphatic polyester based on hydroxyalkanoic acids. They possess exceptional qualities: biocompatibility; FDA approval for clinical use; biodegradability by enzyme and hydrolysis under physiological conditions; low immunogenicity; and good mechanical properties. These critical properties have facilitated their value as sutures, implants for bone fixation, drug delivery vehicles, and tissue engineering scaffolds in pharmaceutical and biomedical applications. However, the hydrophobicity of PLA and its copolymers remains concerns for further biological and biomedical applications. One promising approach is to design and synthesize well-controlled PLA-based amphiphilic block copolymers (ABPs); typical hydrophilic copolymers include poly(meth)acrylates, poly(ethylene glycol), polypeptides, polysaccharides, and polyurethanes. This review summarizes recent advances in the synthesis and self-assembly of PLA-containing ABPs and their bio-related applications including drug delivery and imaging platforms of self-assembled nanoparticles, and tissue engineering of crosslinked hydrogels. © 2011 The Royal Society of Chemistry.

This review summarizes different formats of high-throughput, multi-well, solid-phase microextraction (SPME), including fiber, thin-film and in-tip configurations, with the particular focus on its fit within regulated analysis. New developments of the devices, such as monolithic and biocompatible extraction phases, are covered. Finally, selected applications of the technique, including the analysis of whole-blood samples and automated binding studies, are presented. © 2013 Elsevier Ltd. Source

Epilepsy is one of the most common neurological disorders with 0.8% of the world population. The epilepsy is unpredictable and recurrent, so it is very difficult to treat. In this paper, we propose a new Electroencephalography (EEG) seizure detection method by using the dual-tree complex wavelet (DTCWT) - Fourier features. These features achieve perfect classification rates (100%) for the EEG database from the University of Bonn. These classification rates outperform a number of existing EEG seizure detection methods published in the literature. However, it should be mentioned that several recent works also achieved this perfect classification rate (100%). Our proposed method should be as good as these works since our method only performs the DTCWT transform for up to 5 scales and our method only conducts the FFT to the 4th and 5th scales of the DTCWT decomposition. In addition, we could replace the conventional FFT in our method by sparse FFT so that our method could be even faster. © 2013 Elsevier Ltd. All rights reserved. Source

Prey species possess a variety of morphological, life history and behavioural adaptations to evade predators. While specific evolutionary conditions have led to the expression of permanent, non-plastic anti-predator traits, the vast majority of prey species rely on experience to express adaptive anti-predator defences. While ecologists have identified highly sophisticated means through which naive prey can deal with predation threats, the potential for death upon the first encounter with a predator is still a remarkably important unresolved issue. Here, we used both laboratory and field studies to provide the first evidence for risk-induced neophobia in two taxa (fish and amphibians), and argue that phenotypically plastic neophobia acts as an adaptive anti-predator strategy for vulnerable prey dealing with spatial and temporal variation in predation risk. Our study also illustrates how risk-free maintenance conditions used in laboratory studies may blind researchers to adaptive anti-predator strategies that are only expressed in high-risk conditions.
