The exclusive fishing zone for the artisanal fishery in Chocó Colombia: origins, development, and consequences for artisanal fisheries and food security.

Exclusive Fishing Zones (EFZs) are a type of place-based management tool often used to mitigate conflicts between fishing sectors by granting fishing rights to one of the sectors. This case study enhances our knowledge of the pre- and post-implementation processes associated with EFZs as well as its consequences for fish stocks and artisanal fishers and their families. The study draws upon interviews with artisanal fishers and key informants related to an EFZ established in 2008 in Colombia (the Chocó-EFZ). The findings of this research indicate that conflicts at sea and on land between artisanal and industrial fisheries triggered the Chocó-EFZ process. Results also show some potential benefits of the Chocó-EFZ including: a) mitigating conflicts between artisanal fishers and industrial shrimpers; b) contributing to the food security of artisanal fishing households and sustaining local fish stocks; c) supporting an existing informal community-based management as well as promoting the development of a co-management regime. Potential negative effects of the Chocó-EFZ include: a) displacement of industrial fishing effort and, b) job loss within the industrial shrimp industry. The findings of this research also indicate that there are multiple factors that jeopardize the effectiveness and continuation of the Chocó-EFZ, some of which include diversity of fisheries, power struggles among stakeholders, and disagreement about exclusive access to fish resources.

Using Community Outreach to Build Children’s Resiliency and Critical Literacy through Digital Tools

Grade three students used tablet computers with a pre-selected series of applications over a seven-month period at school and through a community afterschool program. The study determined that these students benefited from differentiated learning in the school environment and online collaborative play in the afterschool centre. Benefits of the exposure to digital tools included: intergenerational learning as children assisted both parents and teachers with digital applications; problem-solving; and enhanced collaborative play for students across environments. Although this study makes a contribution to the field of digital literacy and young learners, the researchers conclude further investigation is warranted, in regards to the inter-relationships between home, school and community as spaces for the learning and teaching of digital technologies.

Making Memorial Student-Ready: Reflections on the First Year Success Experience

In eleven short chapters faculty, academic advising staff and student union representatives discuss aspects of Memorial’s First Year Success Program (piloted as a Teaching Learning Framework initiative 2012-2017). Teaching approaches, curriculum content and policy rationales are covered in a broad view of how and why students identified as least likely to succeed at university can be academically supported. Contributors identify the singular importance of the community that First Year Success provided them and its student participants.

Industrial fault detection and diagnosis using Bayesian belief network

Rapid development in industry have contributed to more complex systems that are prone to failure. In applications where the presence of faults may lead to premature failure, fault detection and diagnostics tools are often implemented. The goal of this research is to improve the diagnostic ability of existing FDD methods. Kernel Principal Component Analysis has good fault detection capability, however it can only detect the fault and identify few variables that have contribution on occurrence of fault and thus not precise in diagnosing. Hence, KPCA was used to detect abnormal events and the most contributed variables were taken out for more analysis in diagnosis phase. The diagnosis phase was done in both qualitative and quantitative manner. In qualitative mode, a networked-base causality analysis method was developed to show the causal effect between the most contributing variables in occurrence of the fault. In order to have more quantitative diagnosis, a Bayesian network was constructed to analyze the problem in probabilistic perspective.

Glia-augmented artificial neural networks: foundations and applications

Information processing in the human brain has always been considered as a source of inspiration in Artificial Intelligence; in particular, it has led researchers to develop different tools such as artificial neural networks. Recent findings in Neurophysiology provide evidence that not only neurons but also isolated and networks of astrocytes are responsible for processing information in the human brain. Artificial neural net- works (ANNs) model neuron-neuron communications. Artificial neuron-glia networks (ANGN), in addition to neuron-neuron communications, model neuron-astrocyte con- nections. In continuation of the research on ANGNs, first we propose, and evaluate a model of adaptive neuro fuzzy inference systems augmented with artificial astrocytes. Then, we propose a model of ANGNs that captures the communications of astrocytes in the brain; in this model, a network of artificial astrocytes are implemented on top of a typical neural network. The results of the implementation of both networks show that on certain combinations of parameter values specifying astrocytes and their con- nections, the new networks outperform typical neural networks. This research opens a range of possibilities for future work on designing more powerful architectures of artificial neural networks that are based on more realistic models of the human brain.

Sedimentology on surface samples from the White Sea

In this study, the grain-size and clay-mineral compositions of 73 surface sediment samples collected in a variety of environmental settings in the White Sea are presented to characterize recent sedimentation processes, reconstruct transport pathways, and identify potential source areas of the terrigenous components. Areas >100 m deep are invariably characterized by silty clay, whereas areas <100 m deep exhibit more heterogeneous grain-size compositions plausibly explained by coastal erosion and (re-)distribution mechanisms, particularly tidal currents. The dominance of sand in the estuarine areas of the Onega and Dvina rivers as well as toward Gorlo Strait connecting the White Sea with the Barents Sea, is attributed to increased current speeds. Illite and smectite are the dominant clay minerals in recent sediments of the southwestern and eastern White Sea sectors, respectively. Their distribution patterns largely depend on the geology of the source areas and mirror surface circulation patterns, especially in Dvina Bay. Smectite is a key clay mineral in White Sea surface sediments as it reveals the dominating influence of the Northern Dvina's runoff on sedimentation and water circulation throughout the basin of the sea. In comparison to other Eurasian shelf seas, the White Sea is characterized by a greater diversity of clay-mineral assemblages, which range from illite- to smectite-dominated sectors containing variable amounts of chlorite and kaolinite.

Manganese deposits from the HMS Challenger stations

This Monograph on Deep-Sea Deposits forms the penultimate volume of the Official Reports on the Scientific Results of the Challenger Expedition. The work connected with the examination and study of the samples of Deep-Sea Deposits, and the preparation of this Report for the press have occupied a very large part of the author's time and attention for nearly twenty years, and his colleague, Professor A. F. Renard, has also given much of his time to the same studies during the past fourteen years. They hope that the completed work may be regarded as an interesting contribution to our knowledge of the ocean, and prove useful to a large number of scientific men, as it is the first attempt to deal systematically with Deep-Sea Deposits, and the Geology of the sea-bed throughout the whole extent of the ocean. There are three Appendices to the volume, the first containing an explanation of the Charts and Diagrams; the second a Report on the Analysis of Manganese Nodules, by John Gibson, Ph.D., of Edinburgh University; and the third Analyses of Deposits and materials from the Deposits by various analysts.

L'influence de l'intervention de l'équipe de psychogériatrie a domicile sur le bien-être psychologique de la personne âgée

L'influence de l'intervention de l'équipe multidisciplinaire de psychogériatrie à domicile sur le bien-être psychologique de la personne âgée. L'organisation des soins de santé a subi plusieurs modifications importantes au cours de la dernière décennie afin de répondre aux besoins engendrés par le vieillissement de la population et de favoriser le maintien à domicile des personnes âgées. Les équipes sous-régionales de psychogériatrie à domicile mises en place en 1986 à Montréal et à Québec sont au coeur de ces modifications. L'existence relativement récente de ce programme a pu contribuer au fait qu'il n'y ait jamais eu d'évaluation auprès des personnes âgées bénéficiaires de ce service. La présente recherche tentera de combler cette lacune. L'objectif visé est de mesurer l'influence de l'intervention de l'équipe sur le bien-être psychologique des sujets. Un plan de recherche quasi expérimental fut élaboré utilisant les clients référés à l'équipe. Selon le plan original il avait été prévu de former un groupe contrôle a posteriori avec les sujets qui n'auraient pas encore reçu l'intervention au post-test, mais ce groupe n'a pu être formé comme souhaité à cause des contraintes rencontrées. L'échantillon par convenance est composé de dix sujets: 6 femmes et 4 hommes âgés entre 61 et 84 ans, bénéficiaires des services à domicile et référés à trois équipes de psychogériatrie à domicile dans la région de Montréal. La grille MUNSH (Memorial University of Newfoundland Scale of Happiness) révisée de Kozma et Stones (1991) fut appliquée à domicile lors d'une entrevue structurée avant et après l'intervention de l'équipe. Les données furent traitées à l'aide de statistiques corrélationnelles et vérificationnelles afin d'établir une relation entre les variables. Les résultats démontrent que l'intervention de l'équipe multidisciplinaire de psychogériatrie à domicile a une influence positive sur le bien-être psychologique de la personne âgée tel que mesuré par la grille MUNSH. Même si statistiquement les résultats des différences au prétest et au post-test permettraient d'établir un lien causal entre l'intervention et l'amélioration du bien-être psychologique de la personne âgée, le fait que le groupe contrôle a posteriori n'a pu être matérialisé a donc apporté des modifications au devis original ne permettant plus de vérifier ce lien causal. La discussion explique les différents facteurs autres que l'intervention ayant pu contribuer à l'amélioration des sujets. Il en ressort toutefois que l'intervention de l'équipe est intensive et spécialisée et que l'intervention en soi semble plus pertinente que sa durée et le délai d'attente.

Positive mental health in adults reporting sexual abuse in childhood

The purpose of this study was to investigate whether a history of child sexual abuse can impact Positive Mental Health in Canadian adults and how frequency of child sexual abuse as well as perceived social support impact Positive Mental Health scores for this population. Data was collected from the Canadian Community Health Survey- Mental Health 2012 and included a sample of 20,529 adults aged 18 and older, living across ten provinces. A one-way ANOVA showed a significant difference between Positive Mental Health scores for individuals reporting a history of child sexual abuse compared to those reporting no history of child sexual abuse. A regression analysis found that reported frequency of child sexual abuse did not significantly impact Positive Mental Health scores for individuals reporting child sexual abuse. It also found that perception of social support was positively related to Positive Mental Health scores and accounted for 25% of the variance in Positive Mental Health scores for individuals reporting child sexual abuse. The implications of these findings are discussed in this study.

Child anxiety, resiliency, and the FRIENDS for Life program

Anxiety disorders are the most commonly diagnosed group of mental disorders in children (Kessler et al., 2012). Resiliency, defined as a child’s ability to successfully overcome an adverse event (Newland, 2014) is believed to be comprised of protective factors such as self-esteem and positive coping strategies (Rutter, 1987). These protective factors are related to child anxiety in that their presence or absence may augment or hinder a child’s resiliency towards anxiety-provoking events and situations (Lo Casico, Guzzo, & Pace, 2013; Thorne, Andrews, & Nordstokke, 2013). The FRIENDS for Life (FFL) program is a school-based anxiety prevention program which aims to decrease anxiety and increase resiliency in 8- to 11-year-old children (Barrett & Sonderegger, 2003). Previous studies have shown FFL to be an effective tool in decreasing anxiety and increasing resiliency; however, not all previous studies have utilized control or comparison groups (Brownlee et al., 2013; Neil & Christensen 2007; Stopa, Barrett, & Golingi, 2011). Moreover, existing FRIENDS literature has not previously considered the potential role of parent anxiety in child outcomes. The present study aimed to evaluate child anxiety, resiliency, and parent anxiety in relation to the FFL program while including a no-treatment control group. It was hypothesized that child anxiety would decrease and child resiliency would increase following FFL. Results obtained from a non-identified school-based sample were not entirely consistent with predictions, such that decreases in anxiety and increases in resiliency were observed in both the experimental and control groups.

The relationship between visual acuity and conceptual tempo

The purpose of this study was to examine the relationship between visual acuity and the two components of conceptual tempo, response accuracy and response latency. Subjects were chosen at random. Each subject was then administered a test of conceptual tempo, the Matching Familiar Figures Test (MFFT) and a test of visual acuity, the Snellen. The only significant relationship found was that between response accuracy and near visual acuity. Subjects with superior visual acuity made significantly fewer errors than did those with average or inferior acuity. It was concluded that visual acuity is an important determinant of MFFT performance. Based on these results, it was recommended that further research examine the relationship between visual acuity and other psychometric measures containing a visual component.

Entre Montesquieu et l'encyclopédie. Voltaire face à l'inquisition Espagnole

Nous étudions la progression, au siècle des Lumières en France, de la critique de l'Inquisition espagnole à partir de l'oeuvre de Montesquieu, en montrant comment Voltaire, principal défenseur de la tolérance religieuse du siècle, a approfondi l'analyse de Montesquieu pour faire de l'Inquisition espagnole un modèle exemplaire du fanatisme religieux, et comment finalement Voltaire a pour sa part influencé les articles sur le sujet rédigés par Louis de Jaucourt pour l'Encyclopédie.

Ad-atoms and their enhancement effects on Pt activity for formic acid oxidation

Formic acid oxidation has been widely studied at Pt as a model reaction to understand fundamental aspects of electrocatalytic reactions in fuel cells. Electrocatalytic oxidation of formic acid takes place through two parallel pathways (direct and indirect). The indirect pathway proceeds via CO as an intermediate, which is known to be responsible for the poisoning of Pt and its consequent decrease in activity. Surface modification of Pt with ad-atoms is known to hinder this poisoning and promote the direct pathway. The incorporation of polymers (polyaniline, polycarbazole, polyindole) as supports also increases activity. Irreversibly adsorbed Sb and Bi on Pt are known to show high electrocatalytic activity for formic acid oxidation. This work presents the dependence of Sb and Bi irreversible adsorption on immersion time, metal solution concentration and pH. The activity of Sb and Bi modified Pt was correlated against immersion time and percent coverage of Pt by ad-atoms. Polyaniline support effects in combination with a Bi modified Pt catalyst showed enhancement in oxidation current compared to Pt-Bi.
