Authors: Troiano Giuseppe , Dioguardi Mario , Cocco Armando , Giannatempo Giovanni , Laino Luigi , Ciavarella Domenico , Berutti Elio , Lo Muzio Lorenzo
Published: October 2016

Objective:

To assess the influence of operator experience on: shaping and centering ability, mean preparation time and presence of canal aberrations of ProTaper Universal and WaveOne systems on simulated root canals.

Materials and Methods:

Sixty S-shaped canals in resin blocks were assigned to four groups (n=15 for each group). Group1 (Experienced operator, ProTaper), Group2 (Experienced operator, WaveOne), Group3 (Inexperienced operator, ProTaper), Group4 (Inexperienced operator, WaveOne). Photographic method was used to record pre- and post-instrumentations images. After superimposition, it has been evaluated presence of canal aberrations and differences in shaping and centering ability between groups.

Results:

WaveOne system produced a lower amount of canal aberrations both in the hand of expert than inexpert operators. However, a WaveOne instrument breakage occurred in the hands of an inexperienced operator. No differences have been found in the evaluation of shaping ability with both systematics. Operator’s experience doesn't influence the shaping ability of ProTaper and WaveOne systems.

Conclusion:

Experience factor could influence the centering ability in the use of both the systematics. However, WaveOne Primary reduce the mean preparation time and the presence of canal aberrations.
Seasonal and Annual Trends in Australian Minimum/Maximum Daily Temperatures
Authors: van Wijngaarden W. A. , Mouraviev A.
Published: October 2016

Seasonal and annual trends in Australian minimum and maximum temperatures were studied. Records of daily minimum and maximum temperatures averaged over each month, extending as far back as 1856 were examined. Over 1/2 million monthly temperature values were retrieved from the Australian Bureau of Meteorology for 299 stations. Each station had an average of 89 years of observations. Significant step discontinuities affected the maximum temperature data in the 19th century when Stevenson screens were installed. The temperature trends were found after such spurious data were removed and averaged over all stations. The resulting trend in the minimum (maximum) daily temperature was 0.67 ± 0.19 (0.58 ± 0.26) oC per century for the period 1907-2014. Decadal fluctuations were evident in the maximum daily temperature with most of the increase occurring in the late 20th century. The minimum and maximum daily temperature trends were also found for the various seasons. The minimum daily temperature trend exceeded the maximum daily temperature trend for all seasons except during June to August. The largest increases in minimum temperature as well as the smallest maximum temperature increases were found for the region north of 30 oS latitude and east of 140 oE longitude. There was also evidence that urban stations had greater increases in maximum daily temperature than those located in a rural environment.

Published: October 2016

El Bosque de Chapultepec es el área verde urbana (AVU) de mayor extensión y con más visitantesde la Ciudad de México, razón por la cual su protección y conservación tiene gran relevanciapor los servicios ambientales y beneficios antropocéntricos que genera. No obstante su trascendencia,hasta la fecha no se ha estudiado la estructura horizontal ni se han generado indicadores de su masaarbolada. Esta situación es extensiva al resto de las AVU de la ciudad y del país y solo se han realizadoocasionalmente estudios florísticos o diagnósticos físico-sanitarios. Se determinaron las característicasdendrométricas y dasométricas del arbolado en la 2ª sección, con base en información registradadurante el inventario total de sus árboles, complementada con la obtenida en 111 sitios de muestreode 500 m2. Se determinó una densidad promedio de árboles de 295/ha; un valor promedio decobertura de copa por árbol de 27,19 m2 y la cubierta del dosel excede 80% de la superficie; mientrasque el valor promedio de área basal por árbol fue de 0,10 m2 y los fustes ocupan 0,32% de dichasuperficie. Los datos de este trabajo servirán como un indicador básico para la 2ª sección y una referenciapara futuros trabajos de investigación y caracterización de masas arboladas urbanas, lo cuales fundamental para sustentar el manejo que requiere el bosque urbano de la Ciudad de México.

Los objetivos del estudio fueron analizar el desarrollo forestal comunitario sustentable en la región norte de México, en los estados de Chihuahua y Durango, considerando la organización comunitaria, flexibilidad, innovación, capacidad de respuesta, competitividad y colaboración, así como comercialización, ante la continua apertura de mercados. También, establecer una estrategia integral para impulsar el desarrollo forestal comunitario sustentable en ambos estados, como una región forestal conjunta-clúster forestal, en el contexto de la globalización económica. En el estudio fueron aplicadas encuestas a ejidos/comunidades, considerando la tipología de las cuatro categorías de productores forestales de Conafor, así como a informantes clave externos y además se incluyeron evidencias documentales. Los resultados muestran que ejidos y comunidades no son competitivos y tienen limitada organización; por esta razón, la estrategia integral propuesta incluye la integración horizontal y vertical de la cadena productiva, así como el empoderamiento de ejidos y participación comunitaria. Esta estrategia integral pretende fomentar la competitividad del desarrollo forestal comunitario sustentable en la globalización.
Reconstrucción de la precipitación estacional con anillos de crecimiento para la región hidrológica Presidio-San Pedro
Authors: Díaz-Ramírez Beatriz , Villanueva-Díaz José , Cerano-Paredes Julián
Published: October 2016

La cuenca alta de la región hidrológica Presido San Pedro genera el agua de uno de los afluentes de Marismas Nacionales en el área limítrofe entre los estados de Sinaloa y Nayarit. En esta cuenca Pinus durangensis es una conífera dominante, pero debido a su explotación intensiva quedan pocos rodales remanentes sin disturbio. Para analizar el potencial dendrocronológico de la especie, se colectaron núcleos de crecimiento de 63 árboles, que se procesaron con técnicas dendrocronológicas convencionales. La inter-correlación ente series (0.463), sensibilidad media (0.309), autocorrelación de primer orden (0.41) y relación señal-ruido (5.24), entre otros parámetros estadísticos indicaron excelente potencial de la especie para estudios dendrocronológicos. Se generaron series de tiempo de madera temprana, tardía y de anillo total que se extendió de 1780 a 2012 (232 años). Los índices de madera temprana, respondieron a la precipitación acumulada promedio del período enero-agosto, procedente de cuatro estaciones climáticas circunvecinas al sitio, por lo que se generó un modelo lineal, para una reconstrucción de lluvia invierno a inicios de verano. La variabilidad hidroclimática detectada fue similar a otras desarrolladas previamente para la región hidrológica Presidio San Pedro, donde El Niño Oscilación del Sur (ENSO) es el fenómeno circulatorio que determina la variación interanual y multianual en la precipitación invernal. No se encontró una relación significativa entre la precipitación de verano y los índices de madera tardía, lo que supone poca variación interanual del Monzón de Norteamérica, no obstante ser causante de 70% de la precipitación anual en esta región hidrológica.

Published: October 2016

Background and objectives

Although patients with CKD are commonly hospitalized, little is known about those with frequent hospitalization and/or longer lengths of stay (high inpatient use). The objective of this study was to explore clinical characteristics, patterns of hospital use, and potentially preventable acute care encounters among patients with CKD with at least one hospitalization.

Design, setting, participants, & measurements

We identified all adults with nondialysis CKD (eGFR<60 ml/min per 1.73 m2) in Alberta, Canada between January 1 and December 31, 2009, excluding those with prior kidney failure. Patients with CKD were linked to administrative data to capture clinical characteristics and frequency of hospital encounters, and they were followed until death or end of study (December 31, 2012). Patients with one or more hospital encounters were categorized into three groups: persistent high inpatient use (upper 5% of inpatient use in 2 or more years), episodic high use (upper 5% in 1 year only), or nonhigh use (lower 95% in all years). Within each group, we calculated the proportion of potentially preventable hospitalizations as defined by four CKD–specific ambulatory care sensitive conditions: heart failure, hyperkalemia, volume overload, and malignant hypertension.

Results

During a median follow-up of 3 years, 57,007 patients with CKD not on dialysis had 118,671 hospitalizations, of which 1.7% of patients were persistent high users, 12.3% were episodic high users, and 86.0% were nonhigh users of hospital services. Overall, 24,804 (20.9%) CKD–related ambulatory care sensitive condition encounters were observed in the cohort. The persistent and episodic high users combined (14% of the cohort) accounted for almost one half (45.5%) of the total ambulatory care sensitive condition hospitalizations, most of which were attributed to heart failure and hyperkalemia. Risk of hospitalization for any CKD–specific ambulatory care sensitive condition was higher among older patients, higher CKD stage, lower income, registered First Nations status, and those with poor attachment to primary care.

Conclusions

Many hospitalizations among patients with CKD and high inpatient use are ambulatory care sensitive condition related, suggesting opportunities to improve outcomes and reduce cost by focusing on better community–based care for this population.

Política de formação para professores do ensino superior e qualidade de ensino: um estudo sobre o programa pedagogia universitária como possibilidade de qualificação docente na perspectiva pedagógico-didática
Authors: Mantovani Isabel Cristina de Almeida , Canan Silvia Regina
Published: October 2016

As reflexões presentes neste artigo têm por tema as políticas de formação pedagógico‐didáticas para professores do ensino superior e qualidade do ensino e resultam de uma pesquisa desenvolvida numa Universidade Comunitária do Interior do Rio Grande do Sul, envolvendo docentes‐bacharéis que procurou responder: “É possível estabelecer relações entre a ausência de formação pedagógico‐didática dos docentes e de políticas definidoras dessa formação e a qualidade do ensino, no Ensino Superior?” Para responder a questão de pesquisa, procurou-se investigar se o programa pedagogia universitária, desenvolvido em serviço pode ser considerado como espaço que supre a falta de formação pedagógico‐didática, e se representa um fator positivo no que se refere à possibilidade de suprir a deficiência nesse campo.
A presença da diferença negra e indígena na educação superior e o processo de ressignificação da universidade brasileira
Authors: Silva José Bonifácio Alves da , Backes José Licínio
Published: October 2016

O artigo traz uma discussão acerca das tensas relações de poder entre diferentes culturas na universidade. A academia e a ciência tornam-se alvos de problematização, pois são questionadas, sobretudo pela presença ativa de negros e indígenas em seu interior, enquanto invenções eurocentradas que concebiam/concebem as culturas brancas como as  únicas fontes  e identificações válidas para a produção do conhecimento e da verdade. Focalizamos, primeiramente, os elementos socioculturais constituintes da universidade e, posteriormente, mostramos os impactos da presença de negros e indígenas reivindicando espaços nas universidades. Essa presença como argumentaremos, ressignifica a universidade, pois os saberes/poderes dos grupos negros e indígenas infiltram-se nos saberes hegemônicos, colocando a hegemonia branca em xeque.

A extensão como expressão da responsabilidade social univesitária
Authors: Marco Ricardo Antonio de , Sarmento Dirleia Fanfa , Menegat Jardelino
Published: October 2016

O Sistema Nacional de Avaliação da Educação Superior de 2004, no seu Eixo 2, Desenvolvimento Institucional e respectivas Dimensões 1 e 3: Missão e o Plano de Desenvolvimento Institucional (PDI) e a Responsabilidade Social da Instituição, destaca a necessidade das Universidades incorporarem em suas atividades de ensino, pesquisa e extensão práticas que evidenciem sua implicação positiva no Desenvolvimento Social. Nesse sentido, este artigo pretende avaliar como a prática da extensão universitária contribui para a consolidação da Responsabilidade Social Universitária. Utilizou-se como método a pesquisa descritiva e análise documental que verificou os documentos institucionais da Universidade do Oeste de Santa Catarina: missão, visão e valores; Plano de Desenvolvimento Institucional e o projeto de extensão Universidade da Melhor Idade de Chapecó (UMIC); e o Sistema Nacional de Avaliação da Educação Superior. A partir dessa inferência, foi possível perceber que a UNOESC, em seus princípios constitutivos e documentos oficiais, valoriza a formação cidadã orientada para a inserção social. Constatou-se que a consolidação da RSU passa necessariamente pelo olhar atento da gestão aos princípios da indissociabilidade entre o ensino, pesquisa e extensão, elementos constitutivos e findos das universidades, que quando não executados adequadamente, contrariam e violam o preceito legal; que projetos de Extensão de cunho inter e transdisciplinar, como a UMIC, apresentam forte contribuição para a consolidação da RSU; paralelamente, restou evidente que isoladamente projetos de Extensão como a UMIC não atingem na plenitude o compromisso social das Universidades, sugerindo que a indissociabilidade esteja presente com a incorporação de ações que promovam Desenvolvimento Social.
Internacionalização da educação superior no Brasil: programas de indução à mobilidade estudantil
Authors: Chaves Vera Lúcia Jacob , De Castro Alda Maria Duarte Araújo de
Published: October 2016

O texto discute a internacionalização da educação superior no Brasil relacionando-a no contexto da crise do capital e sua repercussão no programa de mobilidade estudantil Ciências sem Fronteiras. Apresenta uma reflexão sobre a interferência direta dos organismos multilaterais de financiamento nas políticas de internacionalização da educação superior em que mistura-se princípios de transferência de conhecimentos com razões economicistas e competitivas que se materializa por meio de processos de “cooperação internacional”, tendência que vem se desenhando mundialmente. A internacionalização não é um processo novo no Brasil, mas vem se reconfigurando nos últimos anos por meio de programas e políticas induzidas pelo governo brasileiro, nos quais são enfatizados a mobilidade estudantil. Nessa perspectiva o governo brasileiro criou em 2011 o Programa Ciência sem Fronteiras (CsF), com a previsão de concessão de 101 mil bolsas em quatro anos. O artigo analisa a concessão de bolsas de graduação pelo CsF no período de 2012 a 2014 evidenciando os países de destino para a realização da mobilidade estudantil. Os estudos mostram que a política de indução à mobilidade de estudantes adotada pelo Brasil com o CSF tem contribuído para consolidar a internacionalização no país e que os países mais procurados pelos estudantes brasileiros são aqueles considerados mais desenvolvidos com universidades de ponta na produção do conhecimento.

Reconstrução da matriz pedagógica-pesquisadora: encontro com nossos paradigmas
Authors: Scherre Paula Pereira
Published: October 2016

Este artigo tem uma de suas origens no chamado de autores que indicam a necessidade de desenvolvermos uma Educação, formações docentes e produção de conhecimento científico, com base na Complexidade e na Transdisciplinaridade. Tenho o objetivo de refletir sobre um caminho (trans)formativo de reconstrução de matriz pedagógica-pesquisadora, como tomada de consciência das raízes paradigmáticas subjacentes ao ser e ao fazer profissional, docente e pesquisador. Este encontro foi possível por meio da metodologia de formação e de pesquisa denominada ‘Narrativa Autoformadora’, fruto de um estudo de natureza qualitativa, sistematizada e teorizada ao longo do doutorado em Educação. Como resultado, temos a identificação da matriz vigente, em suas dimensões pedagógica e pesquisadora, o reconhecimento de suas bases no paradigma newtoniano-cartesiano e a abertura para a construção de outra matriz emergente sob o Paradigma da Complexidade e o Paradigma Educacional Emergente. Mesmo sabendo que os diferentes paradigmas continuarão coexistindo em mim, ter a consciência de como me influenciam me permite aprimorar meu ser e meu fazer profissional. Acredito que este tipo de processo (auto)formativo possibilita tomarmos as rédeas dos diferentes tipos e contextos de formação, nos empoderarmos de nossa história e projeto de vida, atribuirmos sentido ao que é aprendido e vivido, valorizarmos conhecimentos, aprendizagens e experiências, em contínuo diálogo com saberes disciplinares e teóricos. Almejo contribuir para que ambientes de aprendizagem (presenciais, virtuais e híbridos) possam ser espaços e tempos de (trans)formação, de autoconhecimento, de pesquisa, de autoria, de sentido, de criatividade e de produção de conhecimentos de si e conhecimentos científicos.

Este relato de experiências apresenta o olhar de cinco formadoras do Grupo de Estudos e Pesquisas em Educação Superior - GEPES/UNIVALI, ao Programa de Formação Continuada para Docentes do Ensino Superior dessa instituição, doravante FC-UNIVALI. O objetivo geral visa destacar experiências relevantes de docentes profissionais formadoras com seus pares no referido Programa. Os objetivos específicos são: refletir sobre o seu significado; identificar os aspectos positivos; descrever conflitos, tensões e dificuldades e, apresentar aspectos indispensáveis das formadoras no ato da formação. As razões norteadoras para elaboração do artigo são: ser formadora da FC-UNIVALI é desafiador, principalmente, por ser um trabalho com seus pares; a necessidade de se socializar experiências, sobre a atuação de formadoras, dada as poucas publicações. A partir dos conteúdos desenvolvidos, neste artigo, tem-se, como consideração final, que ser formadora é exercitar e transitar no campo das atitudes, habilidades e competências da docência, do ser professor reflexivo e pesquisador, dialogando e superando os desafios e enfrentamentos pedagógicos, em prol do desenvolvimento humano, social e da qualidade do ensino superior, estabelecido numa política de ensino institucional. Espera-se que este artigo contribua com outras reflexões, estudos e pesquisas sobre o papel do formador nesse tipo de formação.
O curso de licenciatura em pedagogia: uma análise das adequações normativas e curriculares
Authors: Jeffrey Debora Cristina , Assis Ana Elisa Spaolonzi Queiroz , Grandin Luciane
Published: October 2016

O Curso de Licenciatura em Pedagogia, entre os anos de 2002 e 2015, tem sido influenciado por normativas nacionais que induzem a constituição de um modelo de formação profissional, sem que se estabeleça uma relação à política de formação de professores no Brasil. Neste sentido, o artigo problematiza o processo de adequação normativa e curricular envolvendo o Curso em questão, destacando as principais concepções de formação de professores no país e sua influência em determinações legais e curriculares, a trajetória da legislação na última década, produzida pelo Conselho Nacional de Educação e os núcleos de formação enfatizados. A fim de auxiliar a análise, é retratado o caso de um Curso de Licenciatura em Pedagogia de uma Universidade Estadual de São Paulo e sua dinâmica interna para atender às adequações normativas e curriculares estabelecidas nos últimos anos. Evidencia-se que, houve um número significativo de orientações normativas em âmbito nacional referente aos Cursos de Licenciatura no país. Essas orientações, por sua vez, influenciam diretamente a constituição dos projetos pedagógicos dos Cursos de Licenciatura, sem que a formulação de uma agenda e a constituição de uma política de formação de professores fossem efetivamente implementados.
Electrical, dielectric and photocatalytic properties of Fe-doped ZnO nanomaterials synthesized by sol gel method
Authors: Cherifi Yacine , Chaouchi Ahcène , Lorgoilloux Yannick , Rguiti Mohammed , Kadri Abdelaziz , Courtois Christian
Published: October 2016

Fe-doped ZnO nanoparticles were synthesized by sol gel technique. Fine-scale
and single phase hexagonal wurtzite structure in all samples were confirmed
by SEM and XRD, respectively. The band gap energy depends on the amount of Fe
and was found to be in the range of 3.11-2.53 eV. The electric and dielectric
properties were investigated using complex impedance spectroscopy. AC
conductivity data were correlated with the barrier hopping (CBH) model to
evaluate the binding energy (Wm), the minimum hopping distance (Rmin) and the
density of states at Fermi level, N(EF). Fe doping in ZnO also improved the
photocatalytic activity. Thus, the sample Zn0.95Fe0.05O showed high
degradation potential towards methylene blue (MB), i.e. it degrades 90% of BM
in 90min under UV light.
Crystallization kinetics of glassy Se90In10-xAgx alloys: Observation of Mayer-Neldel rule
Authors: Singh Karishma , Mehta Neeraj , Sharma Sudhir , Kumar Ashok
Published: October 2016

Glassy alloys of Se90In10-xAgx were prepared using melt quenching technique.
Non-isothermal differential scanning calorimetric (DSC) studies were done on
Se90In10-xAgx (x = 0, 2, 4, 6, 8 at.%) glassy alloys at four different
heating rates (? = 5, 10, 15, 20?C/min). Well defined endothermic and
exothermic peaks were obtained at glass transition (Tg) and crystallization
temperature (Tc), respectively. Augis and Bennett?s method was used to obtain
the composition dependent crystallization activation energy (Ec) and the
pre-exponential factor (?0) of the Arrhenius expression. A linear dependence
between ln ?0 and Ec was observed showing the existence of compensation
effects of the Meyer-Neldel type. These compensation effects confirm the
applicability of Meyer-Neldel (MN) rule for the non-isothermal
crystallization in the present case.
Effect of Biomechanical Constraints on Neural Control of Head Stability in Children With Moderate to Severe Cerebral Palsy
Authors: da Costa Carolina Souza Neves , Saavedra Sandra L. , Rocha Nelci Adriana Cicuto Ferreira , Woollacott Marjorie H.
Published: October 2016

Background

External support has been viewed as an important biomechanical constraint for children with deficits in postural control. Nonlinear analysis of head stability may be helpful to confirm benefits of interaction between external trunk support and level of trunk control.

Objective

The purpose of this study was to compare the effect of biomechanical constraints (trunk support) on neural control of head stability during development of trunk control.

Design

This was a quasi-experimental repeated-measures study.

Methods

Data from 15 children (4–16 years of age) with moderate (Gross Motor Function Classification System [GMFCS] IV; n=8 [4 boys, 4 girls]) or severe (GMFCS V; n=7 [4 boys, 3 girls]) cerebral palsy (CP) were compared with previous longitudinal data from infants with typical development (TD) (3–9 months of age). Kinematic data were used to document head sway with external support at 4 levels (axillae, midrib, waist, and hip). Complexity, predictability, and active degrees of freedom for both anterior-posterior and medial-lateral directions were assessed.

Results

Irrespective of level of support, CP groups had lower complexity, increased predictability, and greater degrees of freedom. The effect of support differed based on the child's segmental level of control. The GMFCS V and youngest TD groups demonstrated better head control, with increased complexity and decreased predictability, with higher levels of support. The GMFCS IV group had the opposite effect, showing decreased predictability and increased complexity and degrees of freedom with lower levels of support.

Limitations

Infants with typical development and children with CP were compared based on similar segmental levels of trunk control; however, it is acknowledged that the groups differed for age, cognitive level, and motor experience.

Conclusions

The effect of external support varied depending on the child's level of control and diagnostic status. Children with GMFCS V and young infants with TD had better outcomes with external support, but external support was not enough to completely correct for the influence of CP. Children with GMFCS IV performed worse, with increased predictability and decreased complexity, when support was at the axillae or midribs, suggesting that too much support can interfere with postural sway quality.
Defining Patterns of Sagittal Standing Posture in Girls and Boys of School Age
Authors: Araújo Fábio Azevedo , Severo Milton , Alegrete Nuno , Howe Laura D. , Lucas Raquel
Published: October 2016

Background

Sagittal postural patterns are associated with back pain in adolescents and adults. However, whether postural patterns are already observable during childhood is unknown. Such a finding would confirm childhood as a key period for posture differentiation and thus for chronic pain etiology.

Objective

The aims of this study were to identify and describe postural patterns in girls and boys of school age.

Design

This was a cross-sectional study.

Methods

Eligible children were evaluated at age 7 in the population-based birth cohort Generation XXI in Portugal. Posture was assessed through right-side photographs during habitual standing with retroreflective markers placed on body landmarks. Postural patterns were defined from trunk, lumbar, and sway angles with model-based clusters, and associations with anthropometric measures were assessed by multinomial logistic regression.

Results

Posture was evaluated in 1,147 girls and 1,266 boys. Three postural patterns were identified: sway (26.9%), flat (20.9%), and neutral to hyperlordotic (52.1%) in girls and sway to neutral (58.8%), flat (36.3%), and hyperlordotic (4.9%) in boys. In girls, a higher body mass index was associated with a sway pattern (versus a flat pattern: odds ratio = 1.21; 95% CI = 1.12, 1.29), whereas in boys, a higher body mass index was associated with a hyperlordotic pattern (versus a flat pattern: odds ratio = 1.30; 95% CI = 1.17, 1.44).

Limitations

Photogrammetry as a noninvasive method for posture assessment may have introduced some postural misclassifications.

Conclusions

Postural patterns in 7-year-old children were consistent with those previously found in adults, suggesting that childhood is a sensitive period for posture differentiation. Sagittal morphology differed between girls and boys, emphasizing sex-specific biomechanical loads during a habitual upright position even in prepubertal ages.

Background

There is increasing interest in measuring the quality of survivorship for patients admitted to the intensive care unit for acute respiratory failure (ARF). However, there is substantial variability in patient outcomes reported in studies evaluating these patients, with few data on which outcomes are essential to inform clinical practice.

Objective

The objectives of this study were to determine clinicians’ perspectives on the outcome domains that should always be reported in studies evaluating people who have had ARF after hospital discharge and to compare findings about US and Australian perspectives.

Design

A modified Delphi method was used for the study.

Methods

A survey with 19 possible domains was developed to iteratively elicit clinicians’ perspectives on core outcome domains via a modified Delphi method. The survey was initially administered online. The survey results were then discussed independently at meetings at scientific conferences in the United States and Australia, and the survey was repeated at the meetings after the discussions.

Results

The numbers of participants who responded to both the online and the real-time polling were 44 of 100 (44%) in the United States and 78 of 85 (92%) in Australia. Most respondents were intensive care unit–based clinicians (United States: 33 [75%]; Australia: 76 [97%]). For the 19 domains evaluated, both US and Australian groups ranked physical function and symptoms as the most important domain, with quality of life, cognitive function and symptoms, and survival being the next 3 most important domains. These data yielded a total of 4 domains meeting the criteria for inclusion as core domains at both meetings.

Limitations

Several key constituencies, including patients and caregivers, were not represented in this study; their perspectives are also important and ideally should be included in the development of a comprehensive core outcome set.

Conclusions

Clinicians agreed that physical function and symptoms, quality of life, cognitive function, and survival were domains that should always be measured in research evaluating outcomes for people who have had ARF after hospital discharge.
Sarah Butler’s Irish Tales, a Jacobite Romance
Authors: Cogan Lucy
Published: October 2016

Sarah Butler’s Irish Tales, published in 1716, is a romance set against the historical background of Brian Boru’s victory against the Vikings in 1014. Given the timing of its publication, a year after the Jacobite rebellion of 1715, the work has been read as an allegorical expression of pro-Jacobite sympathy. Yet the tragic romance dominates the work, complicating this interpretation. This article argues that the combination of fictionalized history and romance found in Irish Tales shows the work to be part of a tradition of romance writing by women in support of the royalist or Jacobite cause. Moreover, this article considers how the heroic role played by the female protagonist in these works represents an aesthetic and political response to the failure to restore James ii and his issue to the throne.
Louis Sébastien Mercier et l’esthétique de la force: Passion, virilité et violence amoureuse
Authors: Boucher Geneviève
Published: October 2016

Au chapitre « Abus de la société » du Tableau de Paris (1781–88), Louis Sébastien Mercier (1740–1814) critique l’aplanissement des relations entre les hommes et les femmes et la mollesse des rap ports amoureux, dont l’un des symptômes serait l’absence de violence physique entre les amants. En gros, il déplore que les hommes ne battent plus leur maîtresse. Ces propos aberrants, irrecevables aujourd’hui, mettent en jeu beaucoup plus que des con sidérations sur la place de la femme: ils dialoguent avec un vaste ensemble discursif qui va du débat sur les passions à l’esthétique du sublime, en passant par la critique de la civilité et par l’imaginaire viril. Mercier tisse au sein de son œuvre un large réseau de représentations où l’équilibre s’oppose à la démesure passion nelle, la galanterie à l’amour authentique, la féminisation de la société à la vertu virile et le joli au sublime. Ses réflexions sur la violence amoureuse s’inscrivent dans ce vaste discours et débouchent sur la revendication d’une esthétique de la force qui mesure la qualité littéraire par la violence des affects mis en circulation.

Published: October 2016

The objective of this study was to examine prospective associations of perceptions of driving risk and skill with teenage risky driving. The vehicles of 42 newly licensed teenage drivers were instrumented with a data acquisition system. Objective measures of risky driving [crash and near crash (CNC) and kinematic risky driving (KRD) rates] obtained from accelerometers were aggregated over three 6-month periods (T1, T2, and T3). The Checkpoints Self-Reported Risky Driving Scale (C-RDS) and perceptions of driving risk and driving skills were collected at corresponding 6-month intervals. The results indicated that CNC, KRD, and C-RDS were significantly correlated at T1 to T3. Perceptions of driving risk and skill were not significantly correlated with objective or self-reported measures of risky driving. No evidence was found that perceptions of risk or skill were prospectively associated with risky driving. It was concluded that perceptions of risk and driving skills may have limited utility as objectives of prevention efforts.
Enhancing Pavement Surface Macrotexture Characterization by Using the Effective Area for Water Evacuation

Published: October 2016

Adequate macrotexture characterization is an essential objective for transportation practitioners because primary pavement surface characteristics like friction, tire–pavement noise, splash and spray, and rolling resistance are significantly influenced by pavement macrotexture. This paper proposes an enhanced macrotexture characterization index based on the effective area for water evacuation (EAWE) that better estimates the potential of the pavement to drain water and provides improved correlations with two properties of pavement surfaces that are predominantly affected by macrotexture: friction and noise. A three-step methodology is proposed to compute the index: ( a) a spike-removal procedure that assures the reliability of the texture profile data; ( b) an enveloping profile calculation, which is necessary to delimit the area between the tire and the pavement when contact occurs; and ( c) a definition of the EAWE, which serves as the index for characterizing macrotexture. Comparisons of current mean profile depth (MPD) and proposed EAWE macrotexture indexes by using 32 pavement sections confirmed that MPD overestimated the effective area for water evacuation between a tire and the pavement surface. Correlations for MPD and EAWE indexes with tire–pavement friction and noise were performed, and measurable improvements in correlations were achieved. Results show that it is possible to define a promising index on the basis of the EAWE that realizes advantages over MPD.
Probabilistic Analysis to Quantify the Effect of the Use of a Material Transfer Device on a Smoothness Pay Incentive

Published: October 2016

Use of a material transfer device (MTD) during asphalt paving to provide smoother pavement while eliminating thermal and material segregation is well known. However, the additional operating cost may prevent contractors from investing in an MTD. This study evaluated the effect of MTDs on the smoothness of the finished friction course layer and predicted the incentives or disincentives a contractor may receive by using an MTD. Two empirical models were developed by using simple linear regression analysis to predict the smoothness of the final friction course on the basis of the underlying structural layer smoothness and whether or not an MTD was used. The regression model results were used in Monte Carlo simulations in conjunction with residual analysis techniques to predict, in a probabilistic fashion, the incentives or disincentives that a contractor could receive as a result of the Florida Department of Transportation’s new developmental specification for smoothness. Finally, expected incentives were predicted as a simulation result. Two validation projects with a normalized length of 10 mi showed additional expected incentives of $9,700 and $10,000 when an MTD was used compared with the expected incentives when an MTD was not used. The additional incentives were approximately 30% more than the typical operating cost of an MTD for construction of a 10 lane miles long friction course in Florida.
Assessment of Incentive-Only Ride Specification for Asphalt Pavements

Published: October 2016

Smoothness specifications are used by almost all state transportation agencies, including the Virginia Department of Transportation (DOT), to promote overall quality and optimum ride quality. The Virginia DOT has a ride specification that provides a pay adjustment (incentive or disincentive) depending on the smoothness of the final paved surface. The Virginia DOT’s ride specification also has a provision for waiving the disincentive and applying only the incentive part to projects in which project geometry and so on are perceived to make it difficult for the contractor to achieve the desired ride quality. When applied, the waiver is intended to encourage the contractor to apply additional effort to improve ride quality for otherwise difficult projects. In late 2011, the Virginia DOT’s executive leadership formed an Asphalt Quality Task Force to identify and recommend specific achievable measures to improve the quality of the asphalt paving in Virginia. The task force recommended assessing the feasibility of creating an incentive-only provision default for projects that would otherwise not qualify for application of the regular ride specification. This study documented and critically reviewed the pilot application of the incentive-only provision for rideability on selected asphalt resurfacing schedules for the 2013 construction season. In addition to the incentive-only sites, several lane miles of control sites were also considered. The purpose of the control projects was to compare them with the incentive-only sites to determine if the prospects of added incentives led contractors to alter their paving procedures in pursuit of a higher-quality ride. There was no statistically reliable distinction between the achieved quality of the incentive-only and control sites.
