Coaching efficacy and coaching effectiveness: examining their predictors and comparing coaches' and athletes' reports
Research on the conceptual model of coaching efficacy (Feltz, Chase, Moritz, & Sullivan, 1999) has increased dramatically over the past few years. Utilizing this model as the guiding framework, the current study examined: (a) coaching experience and sex as predictors of coaches' coaching efficacy; (b) sport experience, sex, and the match/mismatch in sex between coach and athlete as predictors of athletes' perceptions of their coach's effectiveness on the four coaching efficacy domains; and (c) whether coaches' reports of coaching efficacy and athletes' perceptions of coaching effectiveness differed. Coaches (N = 26) and their athletes (N = 291) from 8 individual and 7 team sports drawn from British university teams (N = 26) participated in the study. Coaches completed the Coaching Efficacy Scale (CES), while athletes evaluated their coach's effectiveness using an adapted version of the CES; coaches and athletes also responded to demographic questions. Results indicated that, in coaches, years of coaching experience positively predicted technique coaching efficacy, and males reported higher game strategy efficacy than females. In athletes, sport experience negatively predicted all perceived coaching effectiveness dimensions, and the mismatch in sex between athletes and their coach negatively predicted perceived motivation and character building coaching effectiveness. Finally, on average, coaches' ratings of coaching efficacy were significantly higher than their athletes' ratings of coaching effectiveness on A dimensions. The findings are discussed in terms of their implications for coaching effectiveness
Student Independent Projects English 2017: Depictions of Colonialism in Eden Robinson's Traplines
In "Queen of the North," the last story of Eden Robinson's short-story collection Traplines, the reader is introduced to the many effects the Canadian residential school system has had on its survivors and the generations that followed in its wake. After reading "Queen of the North" one is essentially compelled to reflect back on the previous stories, read them through the lens of "Queen of the North," draw connections between characters in each of the stories, and consider the impacts that the residential schools may have had on characters in other stories as well. There are many reasons as to why a reader may be impelled to draw these connections between Robinson's fiction and the impacts of colonialism

State-dependent Neural Inhibition by Extracellular Stimulation
Utilizing the Aplysia california buccal ganglia neurons, our research built upon previous findings concerning the presence of neuronal activity states, but demonstrate that these states play a role in the cell’s responsiveness to electrical stimulation. It was demonstrated that fast-firing neurons are more resistant to inhibitory stimulation as compared to slow-firing neurons. NEURON computational modeling revealed differences in ion channel dynamics that may underlie the differences in stimulation responsiveness that are associated with neuronal states
Social media in scholarly communication : a review of the literature and empirical analysis of Twitter use by SSHRC doctoral award recipients
This report has been commissioned by the Social Sciences and Humanities Research Council (SSHRC) to analyze
the role that social media currently plays in scholarly communication as well as to what extent metrics derived
from social media activity related to scholarly content can be applied in an evaluation context.
Scholarly communication has become more diverse and open with research being discussed, shared and
evaluated online. Social media tools are increasingly being used in the research and scholarly communication
context, as scholars connect on Facebook, LinkedIn and Twitter or specialized platforms such as ResearchGate,
Academia.edu or Mendeley. Research is discussed on blogs or Twitter, while datasets, software code and
presentations are shared on Dryad, Github, FigShare and similar websites for reproducibility and reuse. Literature
is managed, annotated and shared with online tools such as Mendeley and Zotero, and peer review is starting to
be more open and transparent. The changing landscape of scholarly communication has also brought about new
possibilities regarding its evaluation. So-called altmetrics are based on scholarly social media activity and have
been introduced to reflect scholarly output and impact beyond considering only peer-reviewed journal articles
and citations within them to measure scientific success. This includes the measurement of more diverse types of
scholarly work and various forms of impact including that on society.
This report provides an overview of how various social media tools are used in the research context based on
1) an extensive review of the current literature as well as 2) an empirical analysis of the use of Twitter by the 2010
cohort of SSHRC Doctoral Award recipients was analyzed in depth. Twitter has been chosen as one of the most
promising tools regarding interaction with the general public and scholarly communication beyond the scientific
community. The report focuses on the opportunities and challenges of social media and derived metrics and
attempts to provide SSHRC with information to develop guidelines regarding the use of social media by funded
researchers as well support the informed used of social media metrics
Scholarly use of social media and altmetrics : a review of the literature
Social media has become integrated into the fabric of the scholarly communication system in fundamental
ways: principally through scholarly use of social media platforms and the promotion of new indicators on
the basis of interactions with these platforms. Research and scholarship in this area has accelerated since
the coining and subsequent advocacy for altmetrics—that is, research indicators based on social media
activity. This review provides an extensive account of the state-of-the art in both scholarly use of social
media and altmetrics. The review consists of two main parts: the first examines the use of social media in
academia, examining the various functions these platforms have in the scholarly communication process
and the factors that affect this use. The second part reviews empirical studies of altmetrics, discussing the
various interpretations of altmetrics, data collection and methodological limitations, and differences
according to platform. The review ends with a critical discussion of the implications of this transformation
in the scholarly communication system
Backscattering reduction in a twisted water wave channel
We study theoretically and experimentally how to reduce the backscattering of
water waves in a channel with multiple turns. We show that it is not only
possible to cancel backscattering but also to achieve a remarkable transmission
in such geometries. In order to avoid the reflection that naturally arises at
each turn of the waveguide, an anisotropic metamaterial made of closely-spaced
thin vertical plates is used. The efficiency of the metamaterial arrangement
depends only slightly on the frequency of the incident wave, as long as its
wavelength is much larger than the periodicity of the array. This phenomenon is
not restricted only to water wave channels but also applies to any type of
waves with Neumann boundary conditions

National hospital mortality surveillance system: a descriptive analysis.
OBJECTIVE: To provide a description of the Imperial College Mortality Surveillance System and subsequent investigations by the Care Quality Commission (CQC) in National Health Service (NHS) hospitals receiving mortality alerts. BACKGROUND: The mortality surveillance system has generated monthly mortality alerts since 2007, on 122 individual diagnosis and surgical procedure groups, using routinely collected hospital administrative data for all English acute NHS hospital trusts. The CQC, the English national regulator, is notified of each alert. This study describes the findings of CQC investigations of alerting trusts. METHODS: We carried out (1) a descriptive analysis of alerts (2007-2016) and (2) an audit of CQC investigations in a subset of alerts (2011-2013). RESULTS: Between April 2007 and October 2016, 860 alerts were generated and 76% (654 alerts) were sent to trusts. Alert volumes varied over time (range: 40-101). Septicaemia (except in labour) was the most commonly alerting group (11.5% alerts sent). We reviewed CQC communications in a subset of 204 alerts from 96 trusts. The CQC investigated 75% (154/204) of alerts. In 90% of these pursued alerts, trusts returned evidence of local case note reviews (140/154). These reviews found areas of care that could be improved in 69% (106/154) of alerts. In 25% (38/154) trusts considered that identified failings in care could have impacted on patient outcomes. The CQC investigations resulted in full trust action plans in 77% (118/154) of all pursued alerts. CONCLUSION: The mortality surveillance system has generated a large number of alerts since 2007. Quality of care problems were found in 69% of alerts with CQC investigations, and one in four trusts reported that failings in care may have an impact on patient outcomes. Identifying whether mortality alerts are the most efficient means to highlight areas of substandard care will require further investigation
Elasmobranch diversity across a remote coral reef atoll revealed through environmental DNA metabarcoding
As elasmobranchs are becoming increasingly threatened, efficient methods for monitoring the distribution and diversity of elasmobranch populations are required. Environmental DNA (eDNA) metabarcoding is a progressively applied technique that enables mass identification of entire communities and is an effective method for the detection of rare and elusive species. We performed an eDNA metabarcoding survey for fish communities around a coral reef atoll in the Chagos Archipelago (Central Indian Ocean) and assessed the diversity and distribution of elasmobranch species detected within these communities. Our eDNA survey detected 353 amplicon sequence variants (ASVs) attributed to fishes, 12 of which were elasmobranchs. There were no differences in fish communities based on the presence and absence of ASVs between sample depth (surface and 40 m) or sampling habitat, but communities based on read abundance were significantly different between habitats. The dominant elasmobranch species were grey reef (Carcharhinus amblyrhynchos) and silvertip (C. albimarginatus) sharks, and elasmobranch communities were significantly different between sampling depth and habitat. Overall, we find that eDNA metabarcoding can be used to reveal the diversity of elasmobranchs within broader taxonomic assays, but further research and development of targeted metabarcoding primers may be required before it can be integrated into a toolkit for monitoring these species
