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.

Contributions to historical climate change have varied substantially among nations. These differences reflect underlying inequalities in wealth and development, and pose a fundamental challenge to the implementation of a globally equitable climate mitigation strategy. This Letter presents a new way to quantify historical inequalities among nations using carbon and climate debts, defined as the amount by which national climate contributions have exceeded a hypothetical equal per-capita share over time. Considering only national CO2 emissions from fossil fuel combustion, accumulated carbon debts across all nations from 1990 to 2013 total 250 billion tonnes of CO2, representing 40% of cumulative world emissions since 1990. Expanding this to reflect the temperature response to a range of emissions, historical climate debts accrued between 1990 and 2010 total 0.11 °C, close to a third of observed warming over that period. Large fractions of this debt are carried by industrialized countries, but also by countries with high levels of deforestation and agriculture. These calculations could contribute to discussions of climate responsibility by providing a tangible way to quantify historical inequalities, which could then inform the funding of mitigation, adaptation and the costs of loss and damages in those countries that have contributed less to historical warming. © 2015 Macmillan Publishers Limited.

Colloidal CdX (X = Se, S, and Te) and their core/shell quantum dots (QDs) have narrow and size-dependent emission spectra, multicolor excitation with large extinction coefficients, and excellent photostability against photobleaching. Because of these unique photoluminescence properties of QDs over conventional fluorescent organic dyes and fluorescent proteins, QDs are useful for various applications such as biological labeling, biosensing and detection, light emitting diodes (LED), and solar cells (photovoltaics). Toward successful biological applications, control of the surface chemistry of QDs is required, enabling the preparation of QDs with water-solubility (or colloidal stability), biocompatibility, nonspecific adsorption to cells, efficient fluorescence, and active targeting. This highlight describes recent strategies developed for the modification of the surface of CdX-based QDs for biological applications. © 2010 The Royal Society of Chemistry.

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.
