Authors: Schmitt Fernanda , Duarte Valmir , Schafer Gilmar , Bender Renar João 
Published: March 2015

<p>As flores de corte são produtos altamente perecíveis e sua vida pós-colheita deve ser prolongada ao máximo para garantir a fidelidade dos consumidores. Uma possível medida para ampliar o período pós-colheita é a adição de fontes exógenas de carboidratos na solução de manutenção das hastes florais. Neste sentido, no presente trabalho avaliou-se a resposta de hastes florais à adição de sacarose nas soluções de manutenção. Foram utilizadas hastes de gérberas (Gerbera jamesonii) ‘Essandre’ colhidas em produtor comercial. Os experimentos foram conduzidos em delineamento experimental inteiramente casualizado com três repetições e cinco hastes florais por unidade sob condições ambiente de 19,4 °C e umidade relativa superior a 80% experimental. Foram aplicados tratamentos com soluções de sacarose a 2, 2,5 e 5% (p/v) em recipientes de vidro (3,3 L) e contendo um litro de solução. As hastes foram avaliadas para longevidade determinada pelo número de dias de qualidade comercial da flor. Determinou-se também o pH da solução, alongamento das hastes após período de vida em vaso, conteúdo de substâncias de reserva e unidades formadoras de colônia (UFC.g-1) em tecidos das hastes. A adição de sacarose não contribui para o aumento da longevidade de pós-colheita das hastes florais de gérbera ‘Essandre’. A concentração de 2,5% de sacarose resulta em maior quantidade de substâncias de reserva nas hastes florais. Não houve diferença no número de colônias bacterianas com relação a adição de sacarose. O pH das soluções com adição de sacarose apresenta uma queda, a partir do terceiro dia após o início das avaliações. </p>

<p>A germinação assimbiótica é um dos principais métodos de multiplicação de Orchidaceae. Entretanto, a viabilidade das sementes dessa família botânica é susceptível a fatores bióticos e abióticos que podem inviabilizar esse processo. Objetivouse com este trabalho avaliar o efeito do período de armazenamento, de tratamento pré-germinativo e do tempo de cultivo sobre a porcentagem de germinação das sementes de <em>Brassavola tuberculata </em>e também verificar se o procedimento amostral do teste de tetrazólio é eficaz para predizer a porcentagem de germinação da espécie. O delineamento experimental utilizado foi o inteiramente casualizado e os tratamentos foram arranjados em esquema de parcelas sub-subdivididas, sendo alocados na parcela os tempos de armazenamento (até 360 dias), na subparcela os tratamentos pré-germinativos (embebição com água destilada ou com 4 mg L-1 de GA3) e na sub-subparcela os tempos de cultivo (15 ou 30 dias), com quatro repetições. O tratamento pré-germinativo com GA3 propicia aumento na porcentagem de germinação de <em>B. tuberculata </em>somente até os 130 dias de armazenamento. Sementes não submetidas a este fitorregulador podem ser armazenadas por 360 dias com porcentagem de germinação acima de 50%. <em>B. tuberculata </em>apresenta maior porcentagem de germinação aos 30 dias de cultivo tanto para sementes submetidas a tratamento pré-germinativo quanto para as não submetidas e, o teste de tetrazólio, efetuado de maneira amostral, pode ser utilizado apenas para indicação da viabilidade das sementes armazenadas. </p>

Published: March 2015

<p>A produção de flores de corte constitui uma atividade importante, cuja comercialização exige técnicas de conservação que contribuam para manter a qualidade floral após a colheita. Assim, objetivou-se avaliar diferentes pontos de abertura da espata, na colheita de hastes florais de copo-de-leite e seu efeito na conservação pós-colheita em duas formas de armazenamento, temperatura ambiente e em câmara fria. As hastes foram colhidas pela manhã, adotando 3 estádios diferentes de abertura da espata: espata fechada, 1/3 aberta e aberta. As hastes florais foram padronizadas quanto ao tamanho da pseudo-haste em 40 cm e armazenadas em câmara fria a 4 °C e em temperatura ambiente a 20 °C. As avaliações foram realizadas por 7 dias consecutivos, observando a qualidade visual das hastes florais, expansão da espata em comprimento e largura e a presença de pólen. Observou-se que não<br />houve diferença qualitativa entre todos os estádios de colheita quando as hastes foram armazenadas em câmara fria, sendo que as hastes florais permaneceram na classe qualitativa A1, já em temperatura ambiente, as inflorescências colhidas fechadas e 1/3 abertas apresentaram melhor qualidade, permanecendo na mesma classe qualitativa. As hastes colhidas fechadas e 1/3 abertas,<br />armazenadas em câmara fria ou em temperatura ambiente, expandiram até o final da avaliação, sem apresentar necrose e murcha da espata, contudo, não completaram o processo de abertura. Conclui-se que as hastes florais colhidas com a espata fechada e espata 1/3 aberta continuam o processo de abertura da espata, mas não atingem a abertura completa, contudo apresentam maior<br />durabilidade, independentemente da condição de armazenamento.</p>

Published: March 2015

<p>Hastes de folhagem de corte de antúrio (Anthurium andraeanum L.) f. cv. Apalai foram submetidas a dois experimentos. No primeiro experimento, utilizou-se a solução de pulsing com sacarose nas concentrações de 0%, 2%, 4%, 6% e 8%, e o segundo experimento foi a pulverização de acido giberélico nas concentrações de 0, 100, 200, 300 e 400 mg L-1, todos os experimentos foram mantidos em temperatura ambiente de armazenamento. O tratamento com sacarose não foi eficiente nem na manutenção da coloração bem como no peso das hastes, mas para o ácido giberélico o melhor tratamento aplicado foi a concentração de 200 mg<br />L-1 mantendo as notas mais altas. O tratamento com ácido giberélico possibilitou um armazenamento eficiente durante 22 dias.</p>

Medidas dinámicas de predictibilidad en el índice S&P 500 y sus determinantes
Authors: Ospina Holguín Javier Humberto 
Published: March 2015

El objeto de este estudio es medir la predictibilidad del índice accionario estadounidense S&P 500 y establecer posibles determinantes de esta predictibilidad. La predictibilidad se ha estudiado ampliamente, pero en pocos casos mediante medidas dinámicas y per se, como se hace aquí. Para establecer la predictibilidad se utilizan la medida eta del campo de las redes neuronales, el valor p del test de la razón de varianzas del campo de la econometría financiera y el análisis de fluctuación sin tendencia del campo de la econofísica. Se construye un algoritmo de inversión basado en las medidas dinámicas de predictibilidad que es mejor que la estrategia de comprar y mantenerse en el periodo estudiado. Para la medida más promisoria, se establece una relación empírica entre la predictibilidad y varios factores económicos y financieros. El panorama que arroja este estudio es el de un mercado que no es estáticamente predecible, sino cuya predictibilidad evoluciona dinámicamente en el tiempo, lo cual es compatible con la hipótesis del mercado adaptativo.

Islamic Law and the Management of Natural Resources in Seventeenth and Eighteenth Century Ottoman Syria
Authors: Joseph Sabrina 
Published: March 2015

Abstract
Drawing on evidence from seventeenth and eighteenth century Islamic legal sources in Ottoman Syria, the paper examines the laws governing the use and management of natural resources, particularly for agricultural production. Islamic jurists played a key role in mediating the state's relationship with local populations and legitimising local practices and customs that governed land and water use. Often, this translated into laws which prioritised protecting the public good while not necessarily challenging existing power structures. The paper also explains how pious endowments ( waqfs ) were integral to the management of land and water resources in Ottoman Syria. The study sheds light on indigenous narratives regarding the environment and how Islamic law adapted to social and economic circumstances on the ground. Ultimately, the law contributed to ensuring the socio-cultural sustainability of 'management' strategies implemented by local populations vis à vis the environment.
Expanding the Space for Future Resource Management: Explorations of the Timber Frontier in Northern Europe and the Rescaling of Sustainability During the Nineteenth Century
Authors: Lotz Christian 
Published: March 2015

Abstract
Analysing international forestry congresses and (by way of example) the exploration of Northern Norway and Finland in the late nineteenth and early twentieth centuries, the article examines the changing conditions of natural resource management in the Baltic and North Sea regions. From the mid-nineteenth century onward, the overall increasing consumption of wood and the advancing timber frontier in Northern Europe questioned the Western European perception of Northern Europe as possessing inexhaustible woodlands. At the same time, the expanding railway network in Central Europe overran traditional (local) concepts of sustainable forest management. Since 1873, at international congresses, experts have debated the consequences of these spatial changes for the future prospects of forestry. On the one hand, pessimistic voices warned about a coming worldwide shortage of timber. On the other hand, optimistic statements saw the railway as a solution, as it allowed for timber to be transported wherever rails were laid. In the countries of the Baltic and North Sea regions, state authorities, as well as forestry academies, took up the debate and tried to improve their knowledge of accessible forest resources, for instance by sending expeditions to the woodlands of Northern Europe. The expanding railway network as well as the accumulation and cross border circulation of new knowledge about forest resources led to an ongoing process of rescaling sustainability: forestry experts continuously tried to keep in step with the changing spatial conditions of forestry planning (timber frontier, railway network) and at the same time fostered these changes. Experts suggested and advocated either spatial limits - for instance laws for regional forest protection - or further spatial extensions - such as new railway lines or channels - in order to shape the spatial framework of future forest management.
Sensorica – Nouveau modèle d’affaires ou mode passagère ?
Authors: d’Amours Liette 
Published: March 2015

Fondé en 2011, le réseau Sensorica compte actuellement 120 membres provenant de multiples horizons (design, ingénierie, fabrication, marketing, etc.). Ces individus et ces organisations partagent tous un objectif commun : la conception de senseurs et de systèmes intelligents. L’entreprise fonctionne non seulement sans patron, sans budget et sans paie hebdomadaire, mais ne possède ni équipement ni usine. Selon Mai Thai, professeure agrégée à HEC Montréal, ce nouveau modèle d’affaires présente cinq grands défis : gérer des troupes sans moyens coercitifs ; recruter sans garantie de salaire ; mesurer adéquatement la contribution de chacun ; réduire les vulnérabilités ; et adapter la structure aux législations actuelles. À la lumière de ces constats, une interrogation surgit : le modèle d’affaires de Sensorica est-il viable ?
Watson d’IBM, le petit futé de l’informatique cognitive
Authors: Foster Yvan 
Published: March 2015

Il est indéniable que les systèmes de santé à travers le monde subissent une crise majeure depuis déjà quelques années. D’aucuns l’ont répété à plusieurs reprises : les coûts des services de santé ne cessent d’augmenter et l’impact d’une population vieillissante n’améliorera pas la situation. Les solutions explorées pour redresser la situation sont multiples, mais il est indéniable que les technologies de l’information font partie de la réponse, en particulier les mégadonnées. C’est là que le logiciel Watson, lancé par IBM en 2011, entre en scène.

Student Learning Outcomes in Response to Concept-Based Teaching
Authors: Getha-Eby Teresa J. , Beery Theresa , O’Brien Beth , Xu Yin 
Published: March 2015

Background:
Concept-based teaching (CBT) has been found to better facilitate students’ meaningful learning than traditional pedagogy, but little research has been conducted in nursing education.

Method:
This mixed-methods study investigated meaningful learning in nursing students. Quantitative data were extracted from archived records and analyzed through multiple regression to compare two groups: students who received CBT and students who received traditional teaching.

Results:
Students’ pretest scores were the best predictor of meaningful learning gain (i.e., difference between pre- and post-test higher order thinking [HOT] scores). No significant between-group differences were noted. Qualitative data were collected from 22 CBT students, purposefully selected for their HOT scores, and analyzed through flow mapping. Integrative analysis found that students who verbalized a greater number of knowledge connections had higher HOT scores and a deeper understanding of nursing principles than did students with lower HOT scores.

Conclusion:

CBT students’ gain in HOT scores may become more apparent over several semesters. [

Using a Simulated Mass Casualty Incident to Teach Response Readiness: A Case Study
Authors: Shannon Crystal C. 
Published: March 2015

Background:
Recent occurrences of disaster events highlight the need for increased attention to improving students’ knowledge of disaster readiness. Nursing education continues to struggle with the delivery of consistent, effective, and impactful teaching methods for disaster response. This study aimed to explore the effectiveness of using a simulated mass casualty incident (MCI) and Web-based resources to teach the application of disaster nursing concepts.

Method:

Baccalaureate nursing students (
n
= 63) were evaluated on their ability and perceived readiness to respond after participation in a disaster educational session and simulated MCI.

Results:
Quantitative and qualitative data revealed that students developed an increased ability in critical thinking, functionality within the health care team, and learning from their mistakes when responding to a simulated MCI.

Conclusion:

A varied approach of didactic, Web-based, and simulation education is effective in improving student’s perceived readiness for disaster response. Continued efforts are recommended to support student development in disaster response. [

Use of Quick Response Coding to Create Interactive Patient and Provider Resources
Authors: Bellot Jennifer , Shaffer Kathryn , Wang Mary 
Published: March 2015

Background:
Since their creation more than 20 years ago, the proliferation of Quick Response (QR) codes has expanded tremendously. Little was found in the literature to support the innovative use of QR coding in the classroom or in health care provision. Thus, the authors created a doctoral-level practicum experience using QR coding to create interactive, individualized patient or provider resource guides.

Method:
Short, descriptive surveys were used before and after implementation of the practicum experience to determine students’ comfort level using QR technology, their knowledge base, ease of use, and overall satisfaction with the practicum.

Results:
Students reported high levels of satisfaction with this exercise, and all agreed that use of QR coding could have important implications in the clinical environment.

Conclusion:

This practicum experience was a creative, practical, and valuable example of integrating emerging technology into individualized patient care. [

Incorporating the QSEN Competency in Evidence-Based Practice in a Mental Health Clinical Rotation
Authors: Helms Kimberly D. , Walker Laura Pruitt 
Published: March 2015

Background:
Nurse educators continually search for alternative methods of instruction that provide a meaningful experience while meeting clinical objectives. One approach incorporated the Quality Safety Education for Nurses (QSEN) competencies’ evidence-based practice (EBP) into the clinical setting.

Method:
The Paint a Picture of Mental Illness assignment is a creative teaching approach in the Psychiatric Mental Health Nursing course. Students prepare a poster presentation using pictures, drawings, and illustrations demonstrating the mental, emotional, physical, financial, and spiritual impact of the mental illness. Students must perform a library search, locate an evidence-based research article related to best practices in patient care, and summarize pertinent information for presentation to the peer group.

Results:
Nursing students developed an understanding of mental health concepts, addressed real-life issues, researched EBP, and effectively communicated their findings to the peer group.

Conclusion:

This assignment helped students to develop empathy for patients with mental health issues and promoted understanding of patients’ inner experiences. [

A Crustal Structure Model of the Beaufort-Mackenzie Margin, Southern Canada Basin
Authors: Oakey G.N. , Saltus R.W. , Shimeld J.W. 
Published: March 2015

Abstract
Canada and the United States collaborated in geophysical survey operations in the Amerasia Basin from 2007 to 2011 using the Canadian icebreaker CCGS Louis S. St. Laurent and the US icebreaker USCGC Healy. Over 15000 km of bathymetry, sub-bottom profiles, and 16-channel seismic reflection data were acquired over the Canada Basin and Alpha Ridge. Expendable sonobuoys were deployed to collect P-wave refraction and wide angle reflection data to define the regional velocity structure of the sedimentary successions. Although the new seismic profiles tie with existing GSC multichannel seismic lines on the Beaufort Shelf, water-bottom multiples obscure direct correlation of deeper stratigraphic horizons and (at best) basement is poorly imaged.
We present a 2-D gravity and magnetic model for the southern Canada Basin margin and Beaufort-Mackenzie Basin integrating the new LSSL data with an existing deep crustal seismic reflection profile. The model crosses the slope region, where bathymetry shallows, base-of-sediments is deep, and basement is not imaged because of the water-bottom multiple. The density values used in the model are constrained by empirical relationships between velocity and density rock properties; however, magnetic susceptibility values are based on typical values for the inferred crustal lithologies. Velocity analyses of the new sonobuoy data provide constraints on the composition of the sediments, and enable quantitative mapping of continental, oceanic, and transitional domains within the Canada Basin. The 2-D gravity and magnetic forward model provides estimates for basement and Moho depths, the distribution and depths of magnetic sources, and visualization of the underlying crustal architecture controlling basin formation.
Navigating the NSR: The Arctic Ice-Breaking LNG Carrier

Published: March 2015

Abstract
The Yamal LNG Project in Russia involves a number of challenges; besides those of building a liquefaction plant in the Arctic Circle, along with a port accessible all year round for exporting the LNG production, the very issue of marine export - to ensure safe and reliable transportation at optimized costs - hinges on the development of Arctic LNG Carriers capable of breaking ice themselves with no assistance from ice-breakers. This paper addresses some of the preliminary steps and the stages of development of the final solution: the Arctic ice-breaking LNG Carrier.
