Authors: Hoeve Machteld , Colins Olivier F. , Mulder Eva A. , Loeber Rolf , Stams Geert Jan J. M. , Vermeiren Robert R. J. M.
Published: December 2014

Justice-involved youths are more likely to have mental health problems than peers in the community. Therefore, it is important to develop an understanding of the antecedents of mental health problems in this group. The present study examined the association between childhood trauma and mental health problems in juvenile justice-involved adolescent males ( N = 422), comparing childhood-onset with adolescent-onset offenders. Childhood-onset offenders were more likely than adolescent-onset offenders to report mental health and substance use problems, as well as childhood maltreatment. Via structural equation modeling, we found that childhood trauma predicted mental health problems in both offender groups. Multigroup analysis revealed a moderation effect of offender group: The association between trauma and mental health problems was stronger in adolescent-onset offenders than in childhood-onset offenders. Thus, mental health problems were more prevalent in childhood-onset offenders, but these problems were less well-explained by childhood trauma in childhood-onset than in adolescent-onset offenders. Theoretical and practical implications are discussed.
Confirming the multidimensionality of psychologically controlling parenting among Chinese-American mothers

Published: December 2014

Despite the theoretical conceptualization of parental psychological control as a multidimensional construct, the majority of previous studies have examined psychological control as a unidimensional scale. Moreover, the conceptualization of shaming and its associations with love withdrawal and guilt induction are unclear. The current study aimed to fill these gaps by evaluating the latent factor structure underlying 18 items from Olsen et al. (2002) that were conceptually relevant to love withdrawal, guilt induction, and shaming practices in a sample of 169 mothers of Chinese-American preschoolers. A multidimensional three-factor model and bi-factor model were specified based on our formulated operational definitions for the three dimensions of psychological control. Both models were found to be superior to the unidimensional model. In addition, results from the bi-factor model and an additional second-order factor model indicated that psychological control is essentially empirically isomorphic with guilt induction. Although love withdrawal and shaming factors were also fairly strong indicators of psychological control, each exhibited important additional unique variability and mutual distinctiveness. Implications for the conceptualization of love withdrawal, guilt induction, and shaming as well as directions for future studies are discussed.
Gardening Activities and Physical Health Among Older Adults
Authors: Nicklett Emily J. , Anderson Lynda A. , Yen Irene H.
Published: December 2014

Few studies have examined the health-related consequences of gardening among older adults. This scoping review summarizes and characterizes current research that examines the relationship between physical health and participation in planned gardening activities, including establishing, maintaining, or caring for plants. Six databases were searched. Eligible studies were published between 2000 and 2013, were published in English, and assessed different aspects of physical health (e.g., functional ability, energy expenditure, injury) for older adults who had participated in a planned gardening activity. Of the eight eligible studies identified with these criteria, four assessed energy expenditures and four assessed physical functioning. Studies assessing energy expenditures documented that the majority of gardening tasks were classified into low-to-moderate intensity physical activity. The current literature does not provide sufficient evidence of the physical functioning consequences of gardening. Future studies should consider how specific gardening interventions help older adults meet physical activity guidelines.
The Role of Personality in Sport and Physical Activity
Authors: Allen Mark S. , Laborde Sylvain
Published: December 2014

There is now good evidence that athletic success and participation in physical activity can be predicted by personality traits. In this article, we review new studies that have contributed to our understanding of these relationships and outline potential avenues of inquiry to support the development of personality-trait research in exercise and sport. Our review identified a number of novel findings from contemporary studies. In the context of sport performance, new studies have demonstrated that personality traits relate to long-term athletic success, interpersonal relationships, and athletes’ psychological states before, during, and after competitions. In the context of health-related exercise, new studies have demonstrated that personality traits relate to leisure-time sitting time, strength and mobility in old age, and unhealthy (addictive) exercise behaviors. There is also evidence that physical activity contributes to personality change. Our recommendations include a more targeted focus on adolescence (as this is the age of greatest change in personality and sport participation) and a greater consideration of consultant personality traits in applied research and professional practice (given their role in intervention effectiveness).
Fatigue reliability and service life prediction of aluminum naval ship details based on monitoring data
Authors: Soliman Mohamed , Barone Giorgio , Frangopol Dan M
Published: December 2014

The evolution of naval vessels toward high-speed crafts subjected to severe sea conditions has promoted an increasing interest in lightweight high-strength materials. Due to its strength and weight characteristics, aluminum has been proven especially suitable as construction material for hull structures as well as other vessel parts. However, fatigue in aluminum naval crafts needs to be effectively addressed for the proper life-cycle assessment. Structural health monitoring systems constitute effective tools for measuring the structural response and assessing the structural performance under actual operational conditions. In this article, an approach for using structural health monitoring information in the fatigue reliability analysis and service life prediction of aluminum naval vessels is presented. The accumulated fatigue damage and the fatigue reliability are quantified based on structural health monitoring data acquired under different operational conditions, specified by the ship speeds, sea states, and heading angles. Additionally, an approach for estimating the reliability-based fatigue life under a given operational profile is presented. Seakeeping trial data of an aluminum high-speed naval vessel are used to illustrate the proposed approach.

Authors: Huffaker S. , Earp B. E. , Blazar P. E.
Published: December 2014

The value of post-operative radiographs following stabilization of Arbeitsgemeinschaft für Osteosynthesefragen (AO) type A distal radius fractures with volar locking plates is unclear. We examined the value of post-operative radiographs of type A fractures treated with volar locking plates. A retrospective review was performed on all AO type A distal radius fractures treated with volar locking plates between 2007 and 2010 at two institutions. A total of 158 patients receiving 446 sets of post-operative radiographs were included. Reviewing all clinic, emergency, and operative notes, we found that 94% of radiographs were performed as routine follow-up, with no set of post-operative radiographs demonstrating findings of hardware/fracture site complications. All cases requiring further workup or interventions were heralded by patient complaints. Routine post-operative radiographs following volar locking plates for extra-articular distal radius fractures did not demonstrably alter clinical decision making; this is an area where a reduction in resource utilization would not seem to alter clinical quality care, but further studies with larger populations are needed to establish the incidence of radiographic problems prior to symptom occurrence.

Published: December 2014

Monocytes are innate immune cells that play critical roles in inflammation and immune defense. A better comprehension of how monocytes are mobilized and recruited is fundamental to understand their biologic role in disease and steady state. The BM represents a major “checkpoint” for monocyte homeostasis, as it is the primary site for their production and release. Our study determined that the Cx3cr1gfp/+ mouse strain is currently the most ideal model for the visualization of monocyte behavior in the BM by multiphoton intravital microscopy. However, we observed that DCs are also labeled with high levels of GFP and thus, interfere with the accuracy of monocyte tracking in vivo. Hence, we generated a Cx3cr1gfp/+Flt3L−/− reporter mouse and showed that whereas monocyte numbers were not affected, DC numbers were reduced significantly, as DCs but not monocytes depend on Flt3 signaling for their development. We thus verified that mobilization of monocytes from the BM in Cx3cr1gfp/+Flt3L−/− mice is intact in response to LPS. Collectively, our study demonstrates that the Cx3cr1gfp/+Flt3L−/− reporter mouse model represents a powerful tool to visualize monocyte activities in BM and illustrates the potential of a Cx3cr1gfp/+-based, multifunctionality fluorescence reporter approach to dissect monocyte function in vivo.
Coupled Macro and Micro-Scale Modeling of Polyurethane Foaming Processes
Authors: Geier Stephanie , Piesche Manfred
Published: December 2014

Polyurethane foam is used for manufacturing different kinds of products, such as refrigerators, car dashboards or steering wheels. First, we developed a macro-scale simulation tool that is able to predict foam flow in such complex molds. Depending on the location within a product, final properties of polyurethane foams may vary significantly. These properties (e.g. thermal conductivity or impact strength) are strongly dependent on local foam structure. Modeling complex geometries like refrigerators completely on bubble scale is neither possible nor would it be efficient. The computational effort would be enormous. Therefore, we developed a micro-scale model describing bubble growth and the evolution of the foam microstructure in polyurethane foams considering a limited number of bubbles in a representative volume. Finally, we coupled our macro and micro-scale simulation approaches. For that purpose, we introduced tracer particles into our mold filling simulations. We are able to record information about density and temperature changes or varying flow conditions along particle trajectories. This information is then used to set up corresponding simulations on bubble scale. Through this coupling, a basis for studying the evolution of the local foam microstructure in complex geometries is provided.
Evaluation of a Moments-Based Formulation for the Transport and Deposition of Small Inertia Aerosols
Authors: Guichard Romain , Belut Emmanuel , Nimbert Nicolas , Tanière Anne
Published: December 2014

This paper introduces and evaluates a formulation for the modeling of transport and wall deposition of aerosols, written in terms of moments of the particle size distribution (PSD). This formulation allows coupling the moment methods with computational fluid dynamics (CFD) to track the space and time evolution of the PSD of an aerosol undergoing transport, deposition and coagulation. It consists in applying the quadrature method of moments (QMOM) to the diffusion-inertia model of Zaichik et al. [6], associated with the dynamic boundary layer (DBL) approach of Simonin [8] for wall deposition. After presenting the QMOM formulation of the transport equation and of the DBL wall function, the paper presents several test cases in which the method is compared to existing experimental and numerical results. It is shown that the moment formulation of the model does not introduce particular bias compared to its concentration-based formulation. This extension of the diffusion-inertia/DBL approach to the QMOM method hence allows modeling with a good numerical efficiency and at building scale the dynamics of aerosols undergoing transport and modification of their PSD through coagulation and deposition.

Authors: Pereira João M. , Lourenço Paulo B.
Published: December 2014

The work presented in this paper was performed in collaboration with one of the largest Public Transportation Operator in Portugal and addresses the problem of risk assessment due to terrorist actions involving explosions at different levels. First, a region of the Operator is selected. The elements in the Operator's network with the highest associated risk are highlighted for each threat using the COUNTERACT guidelines. Subsequently, from the group of elements with the highest associated risk, an element is selected for structural safety evaluation under blast loading. Through numerical analysis, different explosion scenarios are studied and the behavior of the structure is presented.
Subdivisions of the adult zebrafish pallium based on molecular marker analysis
Authors: Ganz Julia , Kroehne Volker , Freudenreich Dorian , Machate Anja , Geffarth Michaela , Braasch Ingo , Kaslin Jan , Brand Michael
Published: December 2014

Background: The telencephalon shows a remarkable structural diversity among vertebrates. In particular, the everted telencephalon of ray-finned fishes has a markedly different morphology compared to the evaginated telencephalon of all other vertebrates. This difference in development has hampered the comparison between different areas of the pallium of ray-finned fishes and the pallial nuclei of all other vertebrates. Various models of homology between pallial subdivisions in ray-finned fishes and the pallial nuclei in tetrapods have been proposed based on connectional, neurochemical, gene expression and functional data. However, no consensus has been reached so far. In recent years, the analysis of conserved developmental marker genes has assisted the identification of homologies for different parts of the telencephalon among several tetrapod species.

Results: We have investigated the gene expression pattern of conserved marker genes in the adult zebrafish (Danio rerio)pallium to identify pallial subdivisions and their homology to pallial nuclei in tetrapods. Combinatorial expression analysis ofascl1a,eomesa,emx1,emx2,emx3, and Prox1 identifies four main divisions in the adult zebrafish pallium. Within these subdivisions, we propose that Dm is homologous to the pallial amygdala in tetrapods and that the dorsal subdivision of Dl is homologous to part of the hippocampal formation in mouse. We have complemented this analysis be examining the gene expression ofemx1,emx2andemx3in the zebrafish larval brain.

Conclusions: Based on our gene expression data, we propose a new model of subdivisions in the adult zebrafish pallium and their putative homologies to pallial nuclei in tetrapods. Pallial nuclei control sensory, motor, and cognitive functions, like memory, learning and emotion. The identification of pallial subdivisions in the adult zebrafish and their homologies to pallial nuclei in tetrapods will contribute to the use of the zebrafish system as a model for neurobiological research and human neurodegenerative diseases.

FORMAÇÃO MUSICAL DO PROFESSOR GENERALISTA E POSSIBILIDADES DE TRABALHO SIGNIFICATIVO
Authors: Barbosa Maria Flávia Silveira
Published: December 2014

Este trabalho é resultado parcial de estudos que vêm sendo realizados de forma independente com o objetivo de contribuir para a fundamentação teórica e prática de uma pedagogia musical diferente da que tem sido comumente adotada no ensino regular, especialmente nas escolas de Educação Infantil, nas quais as atividades musicais geralmente ficam a cargo de professores não especialistas. Parte-se da análise crítica de documentos oficiais que tratam da formação do professor generalista, com o intuito de verificar a existência (ou não) de indicações acerca da formação musical desse profissional. Entende-se que haja necessidade dessa formação, uma vez que os próprios Referenciais Curriculares Nacionais para a Educação Infantil (RCNEI) incluem uma proposta para a música. Verifica-se, entretanto, que essa nem sempre é a realidade observada em cursos de graduação em Pedagogia. Prossegue-se com a análise da proposta para a Música dos RCNEI, a qual se considera que, conquanto bastante rica e detalhada, não é uma proposta que pode ser facilmente levada a cabo por professores que não tenham uma formação especializada em música, entre outras coisas, por trabalhar, tanto em seus objetivos e conteúdos como em suas orientações didáticas, com conceitos específicos da área. Fundamenta-se, então, na perspectiva histórico-cultural do conhecimento – sobretudo na concepção de linguagem de Lev Vygotski e Mikhail Bakhtin – para apresentar uma proposta didática alternativa. Na elaboração dessa proposta, baseia-se também em autores brasileiros de Educação Musical.http://dx.doi.org/10.14572/nuances.v19i20.980
CONTEXTOS CULTURAIS E CONHECIMENTO ESCOLAR: UM PERCURSO DE PESQUISA COM IMPLICAÇÕES PARA FORMAÇÃO DOCENTE
Authors: Scriptori Carmen Campoy
Published: December 2014

Trata-se de uma pesquisa empírica qualitativa, com possibilidade de aplicação didática, que apresenta resultados de uma investigação sobre a noção do movimento dos corpos, realizada com sujeitos de distintos meios culturais - cultura urbana e de cultura indígena - no Brasil. O estudo mostrou a existência de modelos mentais como fonte de interpretação do real na construção do pensamento de sujeitos de ambas culturas. A fundamentação teórica está em consonância com os estudos psicogenéticos e com a teoria dos Modelos Organizadores de Pensamento. Seu principal objetivo foi investigar as representações mentais dos participantes na compreensão do movimento e queda dos objetos em situações do cotidiano. Parte do pressuposto de que o conhecimento sobre a mecânica do movimento dos corpos supõe uma gênese e evolução de modelos mentais que organizam o pensamento. A coleta de dados se deu por meio de entrevistas semi-estruturadas seguindo os princípios do método clínico piagetiano. Os resultados encontrados contribuem para a formação e prática docente, na medida em que fornecem subsídios para a compreensão dos processos de aprendizagem escolar implicados no ensino das noções de física, particularmente na noção de gravidade específica. O artigo questiona a educação escolar e suas práticas, fazendo uma reflexão crítica do papel da escola na aprendizagem dos conteúdos escolares e apresentando implicações para a aprendizagem de conhecimentos científicos, o papel do ensino escolar e, consequentemente, para a formação docente.http://dx.doi.org/10.14572/nuances.v19i20.983
INCLUSÃO DE ALUNOS SURDOS NO ENSINO MÉDIO: ORGANIZAÇÃO DO ENSINO COMO OBJETO DE ANÁLISE
Authors: Pedroso Cristina Cinto Araujo , Dias Tárcia Regina da Silveira
Published: December 2014

A educação inclusiva, em relação ao surdo, é capaz de oferecer à esse aluno condições para aprender, superando antigos paradigmas discriminatórios e excludentes baseados no oralismo e na comunicação total. Isso significa propiciar uso de procedimentos instrucionais adequados ao surdo, currículo bilíngue e bicultural, formação adequada de professores, intérprete educacional, presença de educadores surdos sinalizadores, interlocução entre surdos e ouvintes e reorganização da escola em todas as suas dimensões. Diante desse panorama, o estudo teve como objetivo analisar as condições de ensino de um aluno surdo inserido no Ensino Médio de uma escola pública estadual, com a presença de um professor fluente em Libras atuando como intérprete. Procederam-se registros sobre as atividades propostas na sala de aula e os relacionamentos do aluno surdo com professores e colegas ouvintes, durante três semestres letivos nas aulas de Língua Portuguesa, Matemática, Química, Física, Biologia, e História. Foi possível constatar que a escola não mudou com a presença do aluno surdo e que o professor fluente em Libras, atuando como intérprete, assume, na sala de aula, a função de professor. Além disso, verificou-se que as ações por ele desenvolvidas possibilitaram a aprendizagem e participação do aluno surdo no processo de ensino-aprendizagem. Com base nos dados obtidos conclui-se a urgência de reorganização da escola na direção da inclusão e do bilinguismo.http://dx.doi.org/10.14572/nuances.v19i20.985
Intensifiers and reflexives in SAE, Insular Celtic and English
Authors: Irslinger Britta
Published: December 2014

Intensifiers and reflexives have been studied as features both in areal linguistics and in the context of substratum hypotheses. While typical SAE languages differentiate between intensifiers and reflexives, English, Welsh and Irish use complex intensifiers for both functions. This article discusses the two strategies with regard to their diachronic developments, starting with PIE. Complex intensifiers are first recorded in Old British and emerge only later in English and Irish. These complex intensifiers are then increasingly used as reflexives, constituting an instance of areal divergence from SAE between the late Middle Ages and the early modern period. Breton, on the other hand, maintains its intensifier - reflexive differentiation due to areal convergence.
PbSe/CdSe Thin-Shell Colloidal Quantum Dots
Authors: Zaiats Gary , Yanover Diana , Vaxenburg Roman , Shapiro Arthur , Safran Aron , Hesseg Inbal , Sashchiuk Aldona , Lifshitz Efrat
Published: December 2014

The present work describes the structural and optical characterization
of PbSe and PbSe/CdSe colloidal quantum dots
(CQDs), the latter being produced by cation exchange of Pb2+
for Cd2+ ions. The cation exchange occurs on preferred
crystallographic facets and results in either non-concentric
CdSe shells or Pb
x
Cd1–x
Se alloyed-shell
layers. The obtained heterostuctures are referred to as
PbSe/CdSe “thin shell” CQDs. The parent
PbSe CQDs are limited to relatively small diameters of
3–4 nm, with absorption edge between 1.0 and
1.3 eV. The steady-state and time-resolved
photoluminescence spectra recorded at various temperatures reveal the
following properties of the PbSe/CdSe CQDs: (1) the
photoluminescence intensity of air-free CQDs is maintained upon their
exposure to oxygen; (2) the band-edge exciton lifetime is extended by
about a factor of two relative to the parent PbSe CQDs. The
experimental results and the effective mass-based calculations suggest
the formation of alloyed shells and highlight a pronounced effect of
core displacement from the CQD center on the heterostructure optical
properties.
Relación entre el abuso del alcohol y la religión en adolescentes mexicanos
Authors: Vargas-Valle Eunice Danitza , Martinez Canizales Georgina
Published: December 2014

Este artículo analiza las asociaciones del abuso de alcohol con la afiliación religiosa, la asistencia a la iglesia y el valor por la religión entre los adolescentes mexicanos, y examina las interacciones entre estas variables independientes, siendo esta su principal contribución.  A partir de la Encuesta Nacional de la Juventud 2010, se emplearon estadísticas descriptivas y modelos multivariados de regresión logística. Los evangélicos exhibieron momios más bajos de abusar del alcohol que los católicos, así como aquellos con un mayor valor por la iglesia y que asistían a esta, acompañados de padres o amigos. Entre los católicos, sólo asistir a la iglesia con los padres se asoció a menores momios de abuso del alcohol, respecto a no ir a la iglesia, lo mismo que los evangélicos, para quienes también asistir con otras personas redujo estos momios. No obstante, asistir a la iglesia con los padres sin tener valor por la religión no protegió a los adolescentes del abuso del alcohol. Tampoco asistir a la iglesia solo (sin compañía) se asoció a esta protección, aun cuando los adolescentes tuvieran un valor alto por la religión. Se concluye que ambos, tanto ser parte de una red social que asiste a la iglesia, como tener valor por esta, condicionan la asociación del abuso del alcohol con la afiliación religiosa y son factores protectores fundamentales contra el abuso del alcohol entre los adolescentes mexicanos.
Exploring identity through Appraisal Analysis
Authors: O’Donnell Michael
Published: December 2014

This paper is concerned with how Appraisal Analysis (Martin and White, 2005) can be used to shed light on the identity that writers/speakers assume when they write/speak, and on the identity these text producers assign to the other voices that participate in the text. Further, we present a methodology of corpus annotation which best supports this approach to identity. The paper shows how Appraisal annotation can be used to reveal the social values held by a writer (and assigned to the other voices introduced into the text) and the affiliations of the writer.
Atenção nos cuidados de enfermagem das escaras quanto às associações terapêuticas

Published: December 2014

O objetivo deste estudo foi levantar os tipos de prescrições e cuidados das escaras associados ao uso da pomada IRUXOL®, bem como os relatos das práticas de curativos usadas pela equipe de enfermagem nas unidades de internação. Foram analisados 19 prontuários de 3 hospitais de ensino do Município do Rio de Janeiro. Os resultados mostraram 8 diferentes tipos de prescrições médicas para o tratamento das escaras, sendo 4 associadas ao Iruxol®. A formulação mais prescrita foi: limpeza com PVP-I + SF 0,9% e IRUXOL®. Observou-se, ainda, que os profissionais de enfermagem aplicaram 17 combinações diferentes com diversas substâncias, sendo que 10 estavam associadas com o Iruxol®. Relataram, também, o uso de 24 produtos / substâncias diferentes na realização dos curativos das escaras. Verificou-se, ainda, o uso indiscriminado de produtos que alteram o pH ( teor ácido - base ) da lesão, fator este que interfere na ação desbridante do Iruxol®.

Authors: Lins Maria Paula Beatriz Estellita , Borges-Andrade Jairo Eduardo
Published: December 2014

O estudo teve como objetivo testar horas de treinamento e utilização de estratégias de aprendizagem no trabalho como variáveis preditoras da expressão de competências de liderança dentre gestores de equipes. Liderança foi definida como o processo pelo qual o gestor e sua equipe interagem de forma ética e se influenciam mutuamente para alcançar objetivos comuns. Participaram do estudo 377 gestores de três órgãos da Administração Pública Federal, que responderam escalas para mensurar estratégias de aprendizagem e competências de liderança, submetidas a análises fatoriais para validação psicométrica. Procedimentos de regressão múltipla foram realizados para testar as hipóteses propostas. Quatro estratégias de aprendizagem (busca de ajuda interpessoal, aplicação prática, reflexão intrínseca e extrínseca, busca de ajuda em material escrito) foram preditoras para competências de liderança. Não houve relação de predição entre horas de treinamento e a variável critério. Os resultados favorecem questionamentos sobre o investimento em treinamentos gerenciais.
Relações customizadas e o ideário de amor na contemporaneidade
Authors: Amorim Ana Nascimento de , Stengel Márcia
Published: December 2014

A regra pós-moderna sugere ausência de discursos e práticas normatizadores, apontando ser possível a homens e mulheres não somente reproduzir modelos sociais, mas inventar formas de parcerias amorosas, o que chamamos de customizar as relações. Consideramos a diversidade das configurações conjugais coexistentes em nossa sociedade e a família moderna que permanece como modelo ideal para a maioria. A partir destas considerações, discutimos em que medida um casal homossexual feminino e um heterossexual das camadas médias de Belo Horizonte estariam repetindo valores mais próximos do modelo conjugal moderno e do ideário romântico, e/ou reinventando formas. Concluímos que a combinação dos ideais e valores assumidos pelos casais não só reflete a ideia de customização, pois cada casal assume um modo singular de se relacionar, como diz também de uma capacidade adaptativa aos nossos tempos.
Tradução, adaptação e exploração de propriedades psicométricas da Escala Interação Trabalho-Família Nijmen (SWING) em uma amostra de professores brasileiros
Authors: Carlotto Mary Sandra , Câmara Sheila Gonçalves
Published: December 2014

Instrumentos que avaliam a relação trabalho-família tendem a enfatizar o conflito entre ambas as instâncias. A Escala Interação Trabalho-Família Nijmen (SWING) avalia a interação trabalho-família considerando a direção e a qualidade da influência. Este artigo analisa a adequação do modelo fatorial original da SWING em uma amostra de 506 professores de escolas públicas municipais de uma cidade da região metropolitana de Porto Alegre, RS. Destes, 91,8% são mulheres, com idade média de 42,6 anos (DP = 9); 61,4% são casados e 70,6% possuem filhos. Foi realizada análise fatorial confirmatória, a qual demonstrou que a distribuição em quatro fatores da escala original (Interferência negativa Trabalho-Família; Interferência negativa Família-Trabalho; Interferência positiva Trabalho-Família; Interferência positiva Família-Trabalho) é adequada para a amostra estudada, com índices satisfatórios de ajustamento e de fidedignidade.

Published: December 2014

This study presents the development and behavior analysis of high performance fiber reinforced cement composites (HPFRCC). The describedmaterials were specifically developed for application as a transition layer: a repair layer that constitutes the stressed chord of reinforcedconcrete beams strengthened in flexure with carbon fiber reinforced polymers (CFRP). Nineteen different composites were produced by thehybridization process, varying the conventional short steel fiber and steel microfiber (manufactured exclusively for this research) contentsto modify the microstructure of the material, thus enhancing the stress transfer process from the cement matrix to the fibers. To analyze theresponse to flexural loading, the composites underwent three point bending tests in notched prism specimens. The response of the materialwas obtained considering strength and tenacity parameters (flexural and fracture). There was evidence of high performance by the composites with a pseudo-hardening behavior.
The Differential Impacts of Episodic, Chronic, and Cumulative Physical Bullying and Cyberbullying: The Effects of Victimization on the School Experiences, Social Support, and Mental Health of Rural Adolescents
Authors: Smokowski Paul R. , Evans Caroline B. R. , Cotter Katie L.
Published: December 2014

Few studies have examined the impacts of past, current, and chronic physical bullying and cyberbullying on youth, especially in rural settings. This study augments this scant literature by exploring the school experiences, social support, and mental health outcomes for rural, middle school youth. The participants for this 2-year longitudinal study were 3,127 youth from 28 middle schools. Participants were classified as nonvictims, past victims (i.e., victimized during Year 1 but not Year 2), current victims (i.e., victimized during Year 2 but not Year 1), and chronic victims (i.e., victimized during both Year 1 and Year 2). Findings illustrated that chronic victimization resulted in the lowest levels of school satisfaction, social support, future optimism, and self-esteem. Chronic victims also reported the highest levels of school hassles, perceived discrimination, peer rejection, anxiety, depression, and externalizing behaviors. In terms of episodic victimization, current year victimization was associated with worse outcomes than past year victimization. Implications and limitations were discussed.

Published: December 2014

Sel-roti is a deep-fat fried, puffed, circular spongy doughnut like indigenous,non- alcoholic fermented cereal product of Nepal. A study was conducted to study the effect of batter ageing on physiochemical and microbial changes and its impact on sensory quality of Sel-roti.Ten samples of batters were aged for 9 h at 3 h interval at temperatures30°C, 40°C and 50°C.After ageing, acidity as lactic acid, reducing sugar and total sugar contents of the batter had increased significantly (P<0.05). The total sugar content of the batter started to decrease after 6 h of ageing. During the ageing period of 3 hour bulk density of products were decreased significantly (p<0.05) for all temperatures of ageing but after 3 hours of ageing it was increased slightly for 40°C. Fat uptake of sel-rotifound to decrease as ageing proceeds. Lactic acid bacteria, yeasts and mold co-existed in sel-rotibatter. LAB and yeast count at the end of 9 hour of aging was higher at 30°C than at 40°C. LAB and yeast count at 50°C was markedly decreased during 9 hour of ageing of batter. Mold count in the samples of batter during aging was decreased at all temperatures. Among study time and temperature of ageing quality of sel-roti prepared from batter aged at 30°C for 6 hour was found to be good in terms of sensory quality and cost effectiveness.  DOI: http://dx.doi.org/10.3126/jfstn.v8i0.11721 J.

Grape Dryer Using Infrared Radiation : An Experimental Study
Authors: Santosh Joshi Snehal , Vishnu Joshi Santosh
Published: December 2014

Preserving fruits by drying is an important operation continued from prehistoric period. Infrared radiation can be used for grape drying purpose. It is unique process and distinctly different from conventional or natural drying. The infrared radiations accelerate drying process with a better control to achieve uniform drying, reduced drying time and ultimately improved product quality. Besides, it requires less floor space and compact system are the additional advantages. In this paper existing natural grape drying process is modified with suitable enclosure containing IR radiators and allied system. Appropriate sensors are used to measure parameters like humidity, temperature and weight of sample. Experimental analysis done with the help of dryer proves the uniform drying of the grapes with the help of infrared radiation.

Published: December 2014

Pectinase are the group of enzymes that catalyze the degradation of pectin substances through de-polymerisation and de-esterification. This study is concerned on the isolation, screening and selection of suitable strain of pectinolytic organism and optimization of cultural conditions for the biosynthesis of pectinase. From the soil samples collected from Lalitpur, Kathmandu, Gulmi, Manang and Dang, 18 fungal colonies were isolated on the basis of halozone formation on Potato dextrose agar and identified. Enzyme production was carried out by submerged state fermentation. The partially purified enzymes showing higher pectinolytic activity were characterized on the basis of temperature of incubation, substrate concentration and pH of the substrate by Dinitro salicylic acid assay (DNSA) method. The fungal isolate showing highest enzyme activity was subjected to optimization of culture medium for the production of enzymes. On optimization, it was found that MG1 (Aspergillus niger) was the most potent strain at 1.5% substrate (pectin) concentration, pH 4.5 and temperature of 30°C. On the enzyme application, the yield of the orange juice, Total Soluble Solid and absorbance increased as the concentration of the enzyme increased and hence increasing the possibility of being used commercially for maximum pectinase production.

The present study was undertaken to study the effect of lemon juice on the quality of tofu prepared from black soyabean. Soymilk tofu coagulated with three different coagulants viz. calcium chloride, calcium sulphate and lemon juice were compared in terms of yield and sensory attributes. The yield percentage and overall acceptability of lemon juice tofu was significantly higher than calcium chloride tofu but no significant change was observed with calcium sulphate tofu. The crude protein, crude fat, crude fiber and ash content of the lemon juice tofu was found to be 51.58%, 13.45%, 6.88% and 3.15 % in dry basis, respectively.

Published: December 2014

The effects of aflatoxin B1 (AFB1) exposure and sodium selenite supplementation on cell apoptosis of jejunum in broilers were studied. A total of 240 one-day-old male AA broilers were randomly assigned four dietary treatments containing 0 mg/kg of AFB1 (control), 0.3 mg/kg AFB1 (AFB1), 0.4 mg/kg supplement Se (+ Se) and 0.3 mg/kg AFB1 + 0.4 mg/kg supplement Se (AFB1 + Se), respectively. Compared with the control broilers, the number of apoptotic cells, the expression of Bax and Caspase-3 mRNA were significantly increased, while the expression of Bcl-2 mRNA and the Bcl-2/Bax ratio were significantly decreased in AFB1 broilers. The number of apoptotic cells and the expression of Caspase-3 mRNA in AFB1 + Se broilers were significantly higher than those in the control broilers, but significantly lower than those in AFB1 broilers. There were no significant changes in the expression of Bax mRNA between AFB1 + Se and control broilers; the expression of Bcl-2 mRNA and the Bcl-2/Bax ratio in AFB1 + Se broilers were significantly lower than those in the control broilers, but significantly higher than those in AFB1 broilers. In conclusion, 0.3 mg/kg AFB1 in the diet can increase cell apoptosis, decrease Bcl-2 mRNA expression, and increase of Bax and Caspase-3 mRNA expression in broiler’s jejunum. However, supplementation of dietary sodium selenite at the concentration of 0.4 mg/kg Se may ameliorate AFB1-induced apoptosis by increasing Bcl-2 mRNA expression, and decreasing Bax and Caspase-3 mRNA expression.

Published: December 2014

In this study, an electroactive polymer (EAP), poly(2,5-bis(N-methyl-N-hexylamino)phenylene vinylene) (BAM-PPV) was investigated as a potential alternative surface pretreatment for hexavalent chromium (Cr(VI))-based aerospace coatings. BAM-PPV was tested as a pretreatment coating on an aerospace aluminum alloy (AA2024-T3) substrate in combination with a non-Cr(VI) epoxy primer and a polyurethane Advanced Performance Coating (APC) topcoat. This testing was undertaken to determine BAM-PPV’s adhesion, corrosion-inhibition, compatibility and survivability in laboratory testing and during outdoor field-testing. BAM-PPV showed excellent adhesion and acceptable corrosion performance in laboratory testing. The BAM-PPV aerospace coating system (BAM-PPV, non-Cr(VI) epoxy primer and polyurethane APC topcoat) was field tested for one year on the rear hatch door of the United States Air Force C-5 cargo plane. After one year of field testing there was no evidence of delamination or corrosion of the BAM-PPV aerospace coating system.

Published: December 2014

Theranostics is an integrated nanosystem that combines therapeutics with diagnostics in attempt to develop new personalized treatments with enhanced therapeutic efficacy and safety. As a promising therapeutic paradigm with cutting-edge technologies, theranostic agents are able to simultaneously deliver therapeutic drugs and diagnostic imaging agents and also monitor the response to therapy. Polymeric nanosystems have been intensively explored for biomedical applications to diagnose and treat various cancers. In recent years, glycol chitosan-based nanoagents have been developed as dual-purpose materials for simultaneous diagnosis and therapy. They have shown great potential in cancer therapies, such as chemotherapeutics and nucleic acid and photodynamic therapies. In this review, we summarize the recent progress and potential applications of glycol chitosan-based fluorescent theranostic nanoagents for cancer treatments and discuss their possible underlying mechanisms.

The olon tree, Zanthoxylum heitzii (syn. Fagara heitzii) is commonly found in the central-west African forests. In the Republic of Congo (Congo-Brazzaville) its bark is anecdotally reported to provide human protection against fleas. Here we assess the insecticidal activities of Z. heitzii stem bark, seed and leaf extracts against Anopheles gambiae s.s, the main malaria vector in Africa. Extracts were obtained by Accelerated Solvent Extraction (ASE) using solvents of different polarity and by classical Soxhlet extraction using hexane as solvent. The insecticidal effects of the crude extracts were evaluated using topical applications of insecticides on mosquitoes of a susceptible reference strain (Kisumu [Kis]), a strain homozygous for the L1014F kdr mutation (kdrKis), and a strain homozygous for the G119S Ace1R allele (AcerKis). The insecticidal activities were measured using LD50 and LD95 and active extracts were characterized by NMR spectroscopy and HPLC chromatography. Results show that the ASE hexane stem bark extract was the most effective compound against An. gambiae (LD50 = 102 ng/mg female), but was not as effective as common synthetic insecticides. Overall, there was no significant difference between the responses of the three mosquito strains to Z. heitzii extracts, indicating no cross resistance with conventional pesticides.
HiCoDG: A Hierarchical Data-Gathering Scheme Using Cooperative Multiple Mobile Elements
Authors: Van Le Duc , Oh Hoon , Yoon Seokhoon
Published: December 2014

In this paper, we study mobile element (ME)-based data-gathering schemes in wireless sensor networks. Due to the physical speed limits of mobile elements, the existing data-gathering schemes that usemobile elements can suffer from high data-gathering latency. In order to address this problem, this paper proposes a new hierarchical and cooperative data-gathering (HiCoDG) scheme that enables multiple mobile elements to cooperate with each other to collect and relay data. In HiCoDG, two types of mobile elements are used: the mobile collector (MC) and the mobile relay (MR). MCs collect data from sensors and forward them to the MR, which will deliver them to the sink. In this work, we also formulated an integer linear programming (ILP) optimization problem to find the optimal trajectories for MCs and the MR, such that the traveling distance of MEs is minimized. Two variants of HiCoDG, intermediate station (IS)-based and cooperative movement scheduling (CMS)-based, are proposed to facilitate cooperative data forwarding from MCs to theMR. An analytical model for estimating the average data-gathering latency in HiCoDG was also designed. Simulations were performed to compare the performance of the IS and CMS variants, as well as a multiple traveling salesman problem (mTSP)-based approach. The simulation results show that HiCoDG outperformsmTSP in terms of latency. The results also show that CMS can achieve the lowest latency with low energy consumption.
Gouvernementalité, intérêt et uniformisation.Une interrogation à partir de l'épistémologie politique occidentale moderne
Authors: Salmon Anne
Published: December 2014

La proposition d’examiner le paradigme d’intérêt sous l’angle du politique n’est pas nouvelle. Bon nombre d’auteurs s’accordent effectivement sur l’idée qu’avant d’être mobilisé par la science économique, il l’a été pour perfectionner l’art de gouverner. Il demeure toutefois un point important qui, faute d’avoir été suffisamment étudié, reste dans l’ombre. À quelle occasion précise et à partir de quelles questions politiques particulières a-t-on recherché dans la notion d’intérêt des éléments de réponses conduisant à affirmer « que l’intérêt gouverne le monde » ? Comment expliquer que les théories politiques antérieures à la Renaissance ne se soient pas emparées de cette notion apparemment si prometteuse : celle d’assurer une certaine uniformité et une certaine prévisibilité des comportements humains ?
