Xanthomonas fuscans subsp. fuscans causing wilt symptoms in bean plants (Phaseolus vulgaris) in Brazil
Authors: Almeida Irene Maria Gatti de , Rodrigues Lucas Matheus Rivero , Beriam Luís Otávio Saggion
Published: April 2015

Common and fuscous blights of bean are diseases widely distributed in the world. The most commonly observed symptoms are spots on leaves, stems, pods and seeds. In December 2009, bean plants cv. Uirapuru showing symptoms of wilt similar to those induced by Curtobacterium flaccumfaciens pv. flaccumfaciens were observed in a commercial crop located in the county of Itararé, State of São Paulo, Brazil. The plants were at the last cycle stage with mature pods and these symptoms were noted in the majority of the growing area. Optical microscopic observations of discolored vascular tissue from diseased stems revealed the presence of bacterial masses oozed from infected tissue, indicating that the disease was caused by bacterial pathogen. Isolations on nutrient agar showed circular, convex, yellow colonies with smooth edges. The causal bacterium was Gramnegative and produced a dark brown pigment in culture medium. Biochemical, cultural and physiological tests confirmed its identity as Xanthomonas fuscans subsp. fuscans(syn. Xanthomonas campestris pv. phaseoli“var. fuscans"). The pathogenicity of the isolates was confirmed by artificial inoculations. Systemic infection has been reported in the literature but these kinds of symptoms are not currently observed in Brazilian fields. Bacterial strains were deposited on the Phytobacteria Culture Collection of Instituto Biológico (IBSBF - www.biologico.sp.gov.br/bacterias/php) under accession numbers 2813 and 3028.

O uso de plantas medicinais no combate as micoses é uma prática comum nas comunidades rurais e, neste contexto, o objetivo desse trabalho foi analisar o perfil de sensibilidade de isolados clínicos de C. neoformans frente a extratos brutos aquosos e antifúngicos de uso hospitalar utilizando a técnica de difusão em disco. Esses produtos naturais foram obtidos de plantas medicinais popularmente utilizadas por comunidades do sertão sergipano. Foram analisados os extratos brutos aquosos de juazeiro (Ziziphus joazeiro Mart.), catingueira (Caesalpinia pyramidalis Tul.), quixabeira (Bumelia sartorum Mart.) e jatobá (Hymenaea courbaril L.). Do juazeiro foi testado o extrato preparado a partir do infuso da entrecasca e da decocção da folha. Da catingueira foi utilizado o extrato preparado a partir do infuso das folhas. Da quixabeira o extrato utilizado foi preparado a partir da decocção da entrecasca e do jatobá maceração da entrecasca. Todos esses produtos naturais foram submetidos aos seguintes tratamentos: exposição ou não a luz ultravioleta e autoclavagem (121ºC por 10minutos). Em paralelo as leveduras patogênicas foram testadas frente aos seguintes antifúngicos de uso hospitalar: anfotericina B, fluconazol, Itraconazol, Miconazol e cetoconazol. Todos os extratos brutos aquosos apresentaram ação antifúngica frente a todas as linhagens clínicas de Cryptococcus neoformans. O tratamento de submeter à autoclavagem e exposição à luz ultravioleta apresentaram melhores resultados de ação antifúngica. Sendo que o tratamento de autoclavar o extrato bruto aquoso prevaleceu estatisticamente com os melhores resultados. Outros estudos de atividade antimicrobiano são necessários para corroborar a ação antimicótica dos produtos natuais testados, como pro exemplo killer-time e fracionamento do teste de micodiluição. No teste de sensibilidade dos antifúngicos realizado foi demonstrado que as leveduras apresentaram resistência preocupante ao fluconazol e a itraconazol pelo método de difusão em disco. Para novos conhecimentos desse perfil de resistência há necessidade de testes de melhor acurácia, como por exemplo, microdiluição. Para tanto, deve-se padronizar os testes de sensibilidade quando há uso de produtos naturais oriundos de plantas medicinais, além de fornecer alternativas de uso aos pacientes cometidos por essa levedura com fornecimento de dados científicos que comprovem a ação dos produtos naturais e plantas medicinais de largo uso no sertão sergipano.

Published: April 2015

Chlorophyll fluorescence is currently used as a rapid diagnostic and nondestructive method to detect and quantify damage on the photosynthetic apparatus of leaves on weeds, crops and ornamental/coniferous trees in response to both environmental stress and herbicides. This study aimed to evaluate chlorophyll fluorescence in guanandi plants (Calophyllum brasiliense) after application of different postemergence herbicides. The experiment was performed in a completely randomized design, with six treatments (control, bentazon, sulfentrazone, isoxaflutole, atrazine and glyphosate) and five replications. The herbicide treatments were applied with a stationary sprayer, and electron transport rate (ETR) was subsequently analyzed with OS5p Multi-Mode Chlorophyll Fluorometer. In the monitored period, guanandi plants subjected to atrazine showed higher sensitivity to chlorophyll fluorescence than the other treatments. Although bentazon is a photosystem II inhibitor, it showed no major changes in electron transport for the studied species and in the monitored period. In summary, ETR is a good parameter to evaluate the effect of some herbicides on Calophyllum brasiliense plants.

Published: April 2015

The aim of this study was to identify and map the weed population in a no-tillage area. Geostatistical techniques were used in the mapping in order to assess this information as a tool for the localized application of herbicides. The area of study is 58.08 hectares wide and was sampled in a fixed square grid (which point spaced 50 m, 232 points) using a GPS receiver. In each point the weeds species and population were analyzed in a square with a 0.25 m2 fixed area. The species Ipomoea grandifolia, Gnaphalium spicatum, Richardia spp. and Emilia sonchifolia have presented no spatial dependence. However, the species Conyza spp., C. echinatus and E. indica have shown a spatial correlation. Among the models tested, the spherical model has shown had a better fit for Conyza spp. and Eleusine indica and the Gaussian model for Cenchrus echinatus. The three species have a clumped spatial distribution. The mapping of weeds can be a tool for localized control, making herbicide use more rational, effective and economical.

Published: April 2015

BACKGROUND: The cystic dilatation of the biliary tract is a rare disease and uncertain origin. It is recognized more frequently in children; however, its incidence comes increasing in adults, representing 20% of the cases. AIM: To evaluate morbimortality rates, evolution and handing of patients with cystic dilatation bile ducts in adults. METHODS: Were evaluated, retrospectively, five adults who had the diagnosis of choledochal cyst and that had been submitted to some surgical procedure. RESULTS: Abdominal pain was the commonest complain to all patients. Jaundice was present in 80%. Ultrasound scanning was done in all the cases as initial examination. CT scan, magnetic resonance imaging and endoscopic retrograde cholangiopancreatography were also done in some patients; however, the diagnosis was established intra-operatively in all cases. The cyst resection with reconstruction of the biliary tract was done in 60%; the cystojejunostomy in 20%; and in 20% biliary tract drainage. CONCLUSIONS: Biliary tract cystic dilatation is a rare disease. However, its incidence is increasing in the adult population, so, it must be thought as differential diagnosis when facing obstructive jaundice.

Published: April 2015

BACKGROUND: Bariatric surgery is considered the only effective method to treat refractory obesity, and especially for those in which clinical treatment was not successful. However, the appearance of food intolerances and clinical manifestations are quite common. AIM: To identify food intolerances and associated them to symptoms in patients undergoing Fobi-Capella technique without gastric ring. METHODS: This was a cross-sectional study of adult patients who had more than one year after surgery. Demographic, anthropometric, weight and preoperative height data were investigated. Nutritional status was classified according to the criteria established by the World Health Organization. It was considered food intolerance the presence of nausea, vomiting, diarrhea or bloating after eating a particular food. RESULTS: The sample consisted of 61 patients who attended the nutritional consultation of which 26 (42.6%) had food intolerance, mostly related to red meat (n=12; 34.3%) during the first six months of operation; there was a significant difference between the periods between 0 and 6 months, and 7 to 12 (p=0.02). Among the symptoms reported by patients, nausea was the most recurrent until the 6th month, but without significant differences between the two periods (p=0.06). CONCLUSION: The Fobi-Capella procedure without gastric ring promoted high frequency of intolerance to meat in general, especially for the red, chicken and fish, on this sequence; nausea was the most frequent symptom. These data suggest the need for adequate nutritional monitoring throughout the postoperative period.

Published: April 2015

O objetivo principal deste artigo é avaliar o comportamento à compressão dos concretos utilizando métodos combinados de testes não destrutivos, como a velocidade de ultrassom e o índice esclerômétrico. Para tanto, foram confeccionados corpos de prova cilíndricos e cúbicos de concretos, com diferentes tipos de brita de acordo com o diâmetro máximo (brita 0,1 e 2) e relações água/cimento. Para a previsão da resistência à compressão dos concretos, os resultados experimentais foram comparados com os resultados teóricos propostos por Rilem [4], Gasparik [5] e Di Leo e Pascale [6]. Como conclusão, pode afirmar-se que existiu uma maior variabilidade nos resultados de velocidade de ultrassom para resistências de concretos acima de 30 MPa, diferentemente do encontrado nos resultados dos índices esclerométricos. As funções potenciais que relacionavam a resistência do cilindro e a velocidade de ultrassom apresentaram comportamentos semelhantes para os concretos com brita 1 e 2, sendo significativamente diferentes aos concretos de brita 0. Já para as medidas dos índices esclerométricos, não se pode verificar diferenças quanto ao tipo de brita nos resultados experimentais. A combinação dos resultados de resistências experimentais e teóricas dos métodos combinados de testes não destrutivos ficou abaixo da reta de representação unitária (experimental/teórico), o que permite concluir que os modelos propostos não foram confiáveis para a previsão da resistência do concreto a partir da velocidade de ultrassom e do índice esclerométrico.
Food Acquisition Strategies, Food Security, and Health Status among Families with Children Using Food Pantries
Authors: Kaiser Michelle L. , Hermsen Joan
Published: March 2015

Social workers working with families must consider the relationship between food insecurity and health. Low-income households often have limited food options and rely on food acquisition strategies to stretch food dollars. This study included 532 adults with children who completed surveys at one of 40 food pantries in 26 counties. This study highlights the ways families acquired food to meet their needs, what health issues were prevalent, and the relationship between food acquisition strategies and food security. Despite using multiple acquisition strategies, 74% were in food-insecure households and 80% were overweight or obese. This study provides evidence that food security and health should be considered when conducting assessments, testing interventions, and developing policies across practice settings.

This study used a relative risk (RR) regression method to explore the extent to which children of caregivers in the Brevard C.A.R.E.S. (Coordination, Advocacy, Resources, Education and Support) wraparound intervention experienced a reduction of maltreatment 6 months post completion. Brevard C.A.R.E.S. is a wraparound intervention designed to reduce and prevent child maltreatment in identified at-risk families of children 0–17 years old. The study of 308 children included 131 whose caregivers completed the intervention and a comparison group of 177 similarly situated children. The study found that children whose caregivers completed the intervention experienced less verified maltreatment than children in the comparison group. These findings have implications to enhance systems of care in the community that seek family interventions to support child maltreatment prevention.

Considerable uncertainties often surround the causes of long‐term changes in population abundance. One striking example is the precipitous decline of southern sea lions (SSL;Otaria flavescens) at the Falkland Islands, from 80 555 pups in the mid 1930s to just 5506 pups in 1965. Despite an increase in SSL abundance over the past two decades, the population has not recovered, with the number of pups born in 2014 (minimum 4443 pups) less than 6% of the 1930s estimate. The order‐of‐magnitude decline is primarily attributed to commercial sealing in Argentina. Here, we test this established paradigm and alternative hypotheses by assessing (1) commercial sealing at the Falkland Islands, (2) winter migration of SSL from the Falkland Islands to Argentina, (3) whether the number of SSL in Argentina could have sustained the reported level of exploitation, and (4) environmental change. The most parsimonious hypothesis explaining the SSL population decline was environmental change. Specifically, analysis of 160 years of winter sea surface temperatures revealed marked changes, including a period of warming between 1930 and 1950 that was consistent with the period of SSL decline. Sea surface temperature changes likely influenced the distribution or availability of SSL prey and impacted its population dynamics. We suggest that historical harvesting may not always be the “smoking gun” as is often purported. Rather, our conclusions support the growing evidence for bottom‐up forcing on the abundance of species at lower trophic levels (e.g., plankton and fish) and resulting impacts on higher trophic levels across a broad range of ecosystems.
Flow management and fish density regulate salmonid recruitment and adult size in tailwaters across western North America
Authors: Dibble Kimberly L. , Yackulic Charles B. , Kennedy Theodore A. , Budy Phaedra
Published: March 2015

Rainbow and brown trout have been intentionally introduced into tailwaters downriver of dams globally and provide billions of dollars in economic benefits. At the same time, recruitment and maximum length of trout populations in tailwaters often fluctuate erratically, which negatively affects the value of fisheries. Large recruitment events may increase dispersal downriver where other fish species may be a priority (e.g., endangered species). There is an urgent need to understand the drivers of trout population dynamics in tailwaters, in particular the role of flow management. Here, we evaluate how flow, fish density, and other physical factors of the river influence recruitment and mean adult length in tailwaters across western North America, using data from 29 dams spanning 1–19 years. Rainbow trout recruitment was negatively correlated with high annual, summer, and spring flow and dam latitude, and positively correlated with high winter flow, subadult brown trout catch, and reservoir storage capacity. Brown trout recruitment was negatively correlated with high water velocity and daily fluctuations in flow (i.e., hydropeaking) and positively correlated with adult rainbow trout catch. Among these many drivers, rainbow trout recruitment was primarily correlated with high winter flow combined with low spring flow, whereas brown trout recruitment was most related to high water velocity.

The mean lengths of adult rainbow and brown trout were influenced by similar flow and catch metrics. Length in both species was positively correlated with high annual flow but declined in tailwaters with high daily fluctuations in flow, high catch rates of conspecifics, and when large cohorts recruited to adult size. Whereas brown trout did not respond to the proportion of water allocated between seasons, rainbow trout length increased in rivers that released more water during winter than in spring. Rainbow trout length was primarily related to high catch rates of conspecifics, whereas brown trout length was mainly related to large cohorts recruiting to the adult size class. Species‐specific responses to flow management are likely attributable to differences in seasonal timing of key life history events such as spawning, egg hatching, and fry emergence.
Do PCAOB Inspection Reports Influence Corporate Executives' Perceptions of Audit Quality and the Likelihood of Switching Auditors?
Authors: Robertson Jesse C. , Stefaniak Chad M. , Houston Richard W.
Published: April 2015

The PCAOB conducts inspections of public company auditors to improve audit quality and build investors' confidence in the quality of financial reporting (PCAOB 2010f). While there is some evidence that the inspection reports could be improving actual audit quality (e.g., Gramling et al. 2011; Carcello et al. 2011), their impact on perceptions of audit quality remains largely unexplored. We investigate the effects of inspection reports, which consistently disseminate negative information in the form of audit deficiencies (and in some cases, quality control criticisms) on perceived audit quality and potential auditor switching. We report the results of an experiment in which 90 corporate executives considered one of three response patterns that firms typically offer across multiple inspection reports: consistently provide concessions, consistently provide denials, or provide mixed responses that consist of both concessions and denials. We find that PCAOB inspection reports generally decrease perceived audit quality, regardless of response pattern, which, in turn, is generally associated with an increased likelihood that executives will consider switching auditors. We offer implications for audit policy and research, including the possibility that, while PCAOB inspections could be improving actual audit quality, the reports could be imposing costs by reducing perceived audit quality and, in turn, increasing the likelihood of auditor changes.

Assessing Practical Thinking of Teachers for Use in Teacher Education,
Authors: Hirose Toshiya , Koda Naoko , Nishio Masahiro , Yamada Yoshiaki
Published: March 2015

This study investigated practical thinking in elementary school teachers (known as invisible practice) evoked through the on-line monitoring method of thinking aloud and the off-line monitoring method of report writing, and relationships between practical thinking and teaching experience. Results indicated that during on-line monitoring, participating teachers spoke more frequently about the actions of students and the content of learning, and made more inferences. During off-line monitoring, teachers more frequently reported on the overall lesson structure and their thinking consisted of more impressions. Teaching experience influenced the perspective of participating teachers: novice teachers focused on the lesson as whole, mid-career teachers attended to teacher-student interactions, and long-career teachers focused on actions by both students and the teacher.
Radiculopathy in the setting of lumbar nerve root compression due to an extradural intraforaminal lipoma: a report of 3 cases
Authors: Loriaux Daniel B. , Adogwa Owoicho , Gottfried Oren N.
Published: April 2015

A true adult spinal lipoma is an exceedingly rare cause of lumbar compression neuropathy. Only 5 cases of true extradural intraforaminal lipomas have been documented in the medical literature. The diagnostic criteria and treatment guidelines for this specific lipoma have yet to be established. This report features 3 histologically confirmed cases of extradural intraforaminal spinal lipomas that recently presented to the authors’ practice. In addition, the literature was surveyed to include the 5 previously reported cases of true adult extradural intraforaminal spinal lipomas. The consistency in presentation, response to surgical intervention, and postoperative recovery in these 8 cases supports surgical intervention at the time of diagnosis. The authors’ findings support elevated clinical suspicion, efficient diagnosis based on MRI, and early surgical intervention for this rare pathological entity. All cases presented in this report were symptomatic and occurred in the absence of other significant pathologies such as general spinal epidural lipomatosis, intradural lesions, tethering, or severe degenerative stenosis or herniated discs. The clinical, neuroradiological, and histological findings characteristic of a true adult extradural intraforaminal lipoma are emphasized to differentiate this lesion from the more common etiologies for lumbar compression neuropathy. Heightened awareness and clinical suspicion for the focal, foraminal spinal lipoma as a cause of radiculopathy symptoms will enable more efficient diagnosis and treatment.
Expanding Sanitary Infrastructure and the Shaping of River History: River Vantaa (Finland) 1876-1982
Authors: Schönach Paula
Published: March 2015

This article investigates the environmental history of the River Vantaa, southern Finland, and its interaction with the spatial development of water-related infrastructures in an urbanising environment. The article argues that the overlapping use of the river as part of both waste water and drinking water infrastructures has shaped its ecological characteristics and consequently influenced communities' possibilities for using it. As a response to hydrological alterations, human activity focused on increasingly manipulating the river water and its flow. The study describes a gradual spatial expansion of the hydrological territory of the Finnish capital and a process of increasingly heavy engineered alterations in order to meet the water-related needs of communities in the region. This happened within the watershed and beyond, both above and under the surface. The study covers the time period from 1876 to 1982.

Flow cytometry is a powerful method, which is widely used for high‐throughput quantitative and qualitative analysis of cells. However, its straightforward applicability for extracellular vesicles (EVs) and mainly exosomes is hampered by several challenges, reflecting mostly the small size of these vesicles (exosomes: ~80–200 nm, microvesicles: ~200–1,000 nm), their polydispersity, and low refractive index. The current best and most widely used protocol for beads‐free flow cytometry of exosomes uses ultracentrifugation (UC) coupled with floatation in sucrose gradient for their isolation, labeling with lipophilic dye PKH67 and antibodies, and an optimized version of commercial high‐end cytometer for analysis. However, this approach requires an experienced flow cytometer operator capable of manual hardware adjustments and calibration of the cytometer. Here, we provide a novel and fast approach for quantification and characterization of both exosomes and microvesicles isolated from cell culture media as well as from more complex human samples (ascites of ovarian cancer patients) suitable for multiuser labs by using a flow cytometer especially designed for small particles, which can be used without adjustments prior to data acquisition. EVs can be fluorescently labeled with protein‐(Carboxyfluoresceinsuccinimidyl ester, CFSE) and/or lipid‐ (FM) specific dyes, without the necessity of removing the unbound fluorescent dye by UC, which further facilitates and speeds up the characterization of microvesicles and exosomes using flow cytometry. In addition, double labeling with protein‐ and lipid‐specific dyes enables separation of EVs from common contaminants of EV preparations, such as protein aggregates or micelles formed by unbound lipophilic styryl dyes, thus not leading to overestimation of EV numbers. Moreover, our protocol is compatible with antibody labeling using fluorescently conjugated primary antibodies. The presented methodology opens the possibility for routine quantification and characterization of EVs from various sources. Finally, it has the potential to bring a desired level of control into routine experiments and non‐specialized labs, thanks to its simple bead‐based standardization.

Le conflit travail-famille médiatise-t-il les effets des conditions de travail sur le stress professionnel ? Une étude auprès du personnel en contact dans le secteur hôtelier
Authors: Mansour Sari , Commeiras Nathalie
Published: April 2015

L’objectif de cet article est d’analyser les incidences des conditions de travail, définies en termes d’exigences et de ressources, sur le stress professionnel, au travers du conflit travail-famille, en retenant comme ancrage théorique la théorie de la conservation des ressources d’Hobfoll (1989) et en intégrant les caractéristiques individuelles et le type d’hôtel en tant que variables modératrices. Une étude a été menée auprès de 648 personnels en contact, dans le secteur hôtelier en France. Les principaux résultats révèlent que le conflit travail-famille a un effet médiateur partiel sur la relation entre les exigences du travail (et plus précisément la charge mentale, la charge physique et l’agression verbale des clients) et le stress professionnel. De même, ils identifient un effet médiateur du conflit travail-famille sur la relation entre le soutien social apporté par le supérieur hiérarchique et par les collègues de travail, et le stress. En outre, les résultats de tests de la médiation modérée montrent que les caractéristiques individuelles et le type d’hôtel sont des variables modératrices.
Le Belize, une société pluriculturelle sans politiques multiculturelles ?
Authors: Hoffmann Odile , Cunin Elisabeth
Published: March 2015

Le Belize, ancienne colonie britannique en Amérique centrale, est généralement décrit en termes de diversité culturelle et de multiplicité des groupes ethniques qui le composent, par les observateurs comme par les administrateurs et gouvernants. Pourtant, depuis son indépendance récente (1981), le gouvernement bélizien n’a pas mis en place de politiques multiculturelles qui accorderaient un traitement différentiel à des individus en raison de leur appartenance ethnique ou raciale, comme on le constate dans les Amériques depuis les années 1980-90. Partant de ce constat, cet article se construit autour d’un double questionnement portant sur les modalités de la mise en place d’un projet national : comment le gouvernement bélizien a-t-il géré l’héritage du «  divide and rule  » colonial qui visait à segmenter la population ? Comment s’est-il adapté au « tournant multiculturel » des années 1980-90 et ses logiques de reconnaissance de la diversité ? Fondée sur deux champs d’application – les politiques culturelles et les politiques agraires-, l’analyse tend à montrer que la prise en compte de l’altérité par les politiques publiques s’inscrit dans la tradition coloniale britannique tout en intégrant les aspirations nées de la longue marche vers l’indépendance, et qu’elle suscite des formes spécifiques de gestion de la différence, au sens de politiques fondées sur des redistributions différentielles en fonction des appartenances collectives.

La question du tact en psychanalyse
Authors: Leroy-Viémon Brigitte , Vivès Jean-Michel
Published: April 2015

Freud, dans son texte sur l’analyse profane (1926a), alertait le lecteur sur le fait que lorsqu’on a trouvé une interprétation, il faut attendre le bon moment pour la communiquer au patient. A la question « à quoi reconnaît-on chaque fois le bon moment ? », il répondait que c’était une question de « Takt », traduit en français par le mot « flair ». Les auteurs de l’article s’emparent de cette question pour en approfondir la portée en clinique psychanalytique. S’appuyant sur les approches phénoménologique et psychanalytique, ils montrent que le tact, dans le cadre de la rencontre clinique, relève d’une dimension temporelle particulière créant de la profondeur dans l’instant. Ce faisant, il se présente comme la possibilité de mettre en résonance le réel humain pour le faire échoir au symbolique.

Modèles d’affaires : transformation numérique en vue

Published: March 2015

Il y a quelques années à peine, le sujet de la réinvention des modèles d’affaires faisait une apparition remarquée dans la littérature spécialisée en gestion. Puis il a été question de génération de nouveaux modèles. Maintenant, il est de bon ton de parler de transformation numérique, celle-ci pouvant être plus ou moins radicale et nécessiter la remise à plat pure et simple d’une entreprise, ou simplement un ajustement plus ou moins majeur et limité dans son champ d’intervention, ou encore une invention vraiment réelle, prenant par exemple la forme d’une entreprise en démarrage ( start-up ) et pouvant entraîner dans son sillage la reconfiguration d’une industrie tout entière. Nous pensons ici au fameux cas précurseur de l’industrie de la musique.
L’état de l’énergie au Québec 2015
Authors: Pineau Pierre-Olivier , Whitmore Johanne , d’Amours Liette
Published: March 2015

Au moment où de grandes décisions doivent se prendre en matière d’énergie, un constat navrant s’impose : au pays, les informations sur les systèmes énergétiques sont éparpillées, difficiles d’accès et manquent parfois de cohérence. Ainsi, bien que le Canada soit le cinquième producteur d’énergie au monde, les gouvernements provinciaux et fédéral ne fournissent pas d’accès global et structuré aux données sur l’énergie. Cette situation peut limiter considérablement notre compréhension du secteur, affecter les perceptions et même compromettre la prise de décision sur les enjeux rencontrés. C’est d’ailleurs pour apporter un meilleur éclairage sur ce secteur que la Chaire de gestion du secteur de l’énergie de HEC Montréal lançait en décembre dernier la toute première édition de l’ État de l’énergie au Québec .
Interprofessional Problem-Based Learning Project Outcomes Between Prelicensure Baccalaureate of Science in Nursing and Doctor of Pharmacy Programs
Authors: Hodges Helen F. , Massey Ann T.
Published: March 2015

Background:

Persistently high medical error rates, caregiver dissatisfaction, and compromised patient safety often result from poorly coordinated, increasingly complex health care. Barriers to interprofessional health professions education persist despite the urgent calls for improved quality and safety. Investigators explored the effects of a problem-based learning (PBL) strategy between prelicensure doctorate of pharmacy (PharmD) and baccalaureate nursing (BSN) students.

Method:

A descriptive design was used to compare the learning gains and satisfaction with a PBL hybrid approach for BSN and PharmD prelicensure student groups over three academic terms.

Results:

Consistent with earlier works, content-based learning gains and student satisfaction were not significantly different between groups. Narrative data provide insight into perceived benefits, barriers, and perspectives of participating students and facilitators.

Conclusion:

Attributes of this pedagogical approach provide opportunity for prelicensure students to explore professional interdependence while adequately mastering fact-based content. [

One Thousand Words: Evaluating an Interdisciplinary Art Education Program
Authors: Klugman Craig M. , Beckmann-Mendez Diana
Published: March 2015

Background:

Art Rounds, an innovative interdisciplinary program, began as a pilot project to determine if use of fine arts instructional strategies would be of benefit in health professional education. Specifically, students were exposed to fine art and taught to use visual thinking strategies (VTS). The initial evaluation of the pilot program revealed improved physical observation skills, increased tolerance for ambiguity, and increased interest in communication skills. More recently, the Art Rounds program has been expanded to an interdisciplinary elective course open to both nursing student and medical students at all levels.

Method:

An evaluation of Art Rounds as a semester- long course was conducted by course faculty and compared to the original pilot program for differences and similarities.

Results/Conclusion:

Outcomes have demonstrated that the use of visual arts and humanities continues to be highly effective in improving students’ physical observation skills and a powerful tool for teaching nursing students how to be skilled clinicians. [

One-Year Results From Clinical Practice of Epimacular Strontium-90 Brachytherapy for the Treatment of Subfoveal Choroidal Neovascularization Secondary to AMD
Authors: Zur Dinah , Loewenstein Anat , Barak Adiel
Published: April 2015

BACKGROUND AND OBJECTIVE:

To evaluate clinical feasibility, safety, and efficacy of epiretinal strontium-90 brachytherapy in subfoveal choroidal neovascularization (CNV) due to age-related macular degeneration (AMD) in eyes unresponsive to repeated anti-VEGF injections.

PATIENTS AND METHODS:

A retrospective, single-center study on patients treated with strontium-90 brachytherapy for CNV secondary to neovascular AMD. Patients underwent pars plana vitrectomy with a single 24 Gy dose brachytherapy. They were re-treated with anti-VEGF injections on an as-needed basis if subretinal or intraretinal fluid was detected on optical coherence tomography imaging.

RESULTS:

Twenty-two patients were treated, and 20 completed 12 months of follow-up. Ten patients maintained stable vision, eight gained vision, and two lost more than three Snellen lines. The mean best corrected visual acuity change from baseline was −8 ± 5.7 letters. A mean of 5.5 ± 4.4 anti-VEGF injections were administered throughout 12 months.

CONCLUSION:

Epimacular brachytherapy is feasible in clinical practice. While some patients benefit from the treatment and need significantly fewer as-needed injections, others appear not to react to irradiation treatment after 1 year of follow-up. Larger numbers of patients are needed to evaluate therapeutic efficacy and to determine which patients can benefit from combined radiation and anti-VEGF therapy.

Effects of Oral Propranolol on a Juxtapapillary Capillary Hemangioma: A Single-Subject Pilot Study
Authors: Tanabe Hirotaka , Sahashi Kazuhiro , Kitano Tomoki , Tomita Yasushi , Saito Akiko M. , Hirose Hiroshi
Published: April 2015

Oral propranolol hydrochloride has been proven effective in treating infantile hemangiomas, and its potential efficacy in choroidal hemangiomas has been suggested. A 57-year-old woman with a juxtapapillary capillary hemangioma was treated with oral propranolol at Nagoya Medical Center in Japan in 2012. Although the condition of this patient partially improved, oral propranolol did not appear to have a critical therapeutic effect. To the authors’ knowledge, this is the first pilot study to describe a case in which oral propranolol was used as a therapeutic approach for a retinal hemangioma.

Design and Development of a Greenland Ice and Metocean Geoportal
Authors: Ross E. , Loos E. , Fissel D.B. , Lapidakis Y. , Zhang O.
Published: March 2015

Completed and planned metocean and ice measurement programs off Greenland's eastern and western coasts result in large and varied datasets characterizing physical phenomena such as icebergs, sea ice, seabed scours, weather, surface waves, ocean currents, and water properties. Future planned measurement programs will expand on the spatial and temporal breadth of these datasets. Other datasets support the analysis of the measurement data including license area locations, bathymetry, glacier calving areas, and notable submarine features.

In order to plan measurement programs, manage the acquired datasets, and use the data for characterization of the physical environment, a web-based geoportal was designed and developed. The geoportal aids scientists and engineers in their discovery and use of metocean and ice data. The geoportal development required balancing two aspects. Firstly, scientists and engineers have extensive needs to upload, organize, search, visualize, analyze, and download large and varied datasets. Secondly, there are inherent limitations of web technologies due to bandwidth, latency, and security constraints. Many design decisions were focused on balancing these issues and are presented here.

The authors will provide an overview of both the technical and legal framework around which emerging technologies can be evaluated and accommodated in the regulatory approval process. With the rapid pace of technology development continuing unabated, regulatory flexibility is required to ensure that regulations keeps pace with innovation.
Forecasting Ice and Weather Conditions for Field Operations in Alaska
Authors: Raye Robert
Published: March 2015

Accurate and reliable surveillance and forecasting of environmental conditions are necessary for safe and efficient oil and gas activities both onshore and offshore. In the Arctic, environmental challenges include seasonal sea ice and low temperature extremes. In the absence of pooled forecasting services and operational-grade forecasting capacity by public weather services, Shell has developed and operates an in-house, Anchorage based forecasting program designed specifically for the demands and requirements of Shell's Alaska operations.

The Shell Ice and Weather Advisory Center (SIWAC), now in its eighth year of operation, has evolved to be the most comprehensive and focused ice and weather forecast operation covering the offshore and coastal areas from the Gulf of Alaska to the Canadian Beaufort Sea. SIWAC consists of a team of fulltime Arctic-experienced forecasters working in a 24/7 rotation schedule and are fully integrated into the operations process, directly engaging with field personnel and decision makers.

Development of differentiating forecast products and services depends not only on an expert team, but also a robust observation program consisting of contracted and public satellite imagery, a network of Metocean buoys, satellite-tracked ice movement beacons, and steady stream of field observations from specially trained personnel aboard marine and aviation assets.

In 2011, Shell entered into a Memorandum of Agreement with the US National Oceanographic and Atmospheric Administration that described a framework for collaboration, communication, and information sharing between the Agency and Industry.

This agreement leverages the strengths of each party and opens Shell's Arctic ice and Metocean data for use within NOAA forecasting offices, numerical model ingestion, climate research, and general public consumers.

Authors: Brandt Hendrik , Frühling Christian , Hollung Achim , Schiemann Marc , Voß Thomas
Published: March 2015

The paper reports results of a feasibility study for the development of a multi-purpose submarine which could be applied to a variety of offshore operations sub-ice and in harsh weather areas. The study has jointly been carried out by ThyssenKrupp Marine Systems GmbH and Statoil ASA. Within the scope of the present study, a concept design for a submarine has been derived which can make a significant contribution to the successful development of arctic oil and gas projects. The versatile vessel is designed for several key missions. Installation, inspection, maintenance, and repair tasks for subsea facilities can be performed in water depths up to 1500 m by the use of an on-board gantry crane, an automatic storage system, and two work class ROVs. The boat can also be used to perform seabed seismic surveys at the same water depth. Furthermore the submarine offers unique abilities to respond to sub-ice oil and gas spills. The paper gives an overview of the vessel's layout, capabilities, main systems, safety features, and operational prospects.
