Published: May 2017

A decisão é algo presente no dia-a-dia de todos, em qualquer esfera, num ambiente cada vez mais dinâmico e que exige respostas rápidas. Há dificuldade em contemplar todos elementos presentes nos processos decisórios, levando os indivíduos a recorrerem a fontes de cunho mais informal, de mais fácil acesso e, entre elas a intuição tem um papel de destaque. Este estudo busca apresentar indícios sobre como a intuição e outros aspectos (experiência, emoções, vieses) atuam no processo decisório instantâneo: seja, tenta-se compreender de que forma executivos fazem uso da intuição, das emoções, da sua experiência neste tipo de decisão. Buscou-se na literatura elementos tanto de processo decisório, como da intuição, nos campos da gestão e da psicologia, identificando pontos de intersecção que permitiram elaborar um instrumento para a condução de entrevistas junto a executivos da área de TI no Sul do Brasil. Foi possível encontrar indícios que levam de que a intuição seja o elemento de maior confiança desses gestores. Além disso, são feitas contribuições ao conceito de intuição do campo da gestão, bem como são apresentados elementos, e como eles se relacionam entre si, para possibilitar o pensamento intuitivo em situações que exigem uma resposta instantânea. São explicitados outros aspectos importantes, como experiência, emoções, vieses, etc. Constituem contribuições a discussão do tema intuição e a identificação de alguns pontos divergentes da literatura estudada. Para gestores em geral, verifica-se que, apesar do desconhecimento e desconfiança, a intuição pode ser uma fonte confiável e que pode ser trabalhada, como qualquer outra habilidade.

Published: May 2017

The objective of the present study was to determine the effect of nitrates on the incidence of gastrointestinal (GI) cancer development. Nitrate converted to nitrite under reducing conditions of gut results in the formation of N-nitrosamines which are linked to an increased gastric cancer risk. A population of 234 individuals with 78 cases of GI cancer and 156 controls residing at urban and rural settings in Nagpur and Bhandara districts of India were studied for 2 years using a case-control study. A detailed survey of 16 predictor variables using Formhub software was carried out. Nitrate concentrations in vegetables and primary drinking water supplies were measured. The logistic regression model showed that nitrate was statistically significant in predicting increasing risk of cancer when potential confounders were kept at base level (P value of 0.001 nitrate in drinking water; 0.003 for nitrate in vegetable) at P < 0.01. Exposure to nitrate in drinking water at >45 mg/L level of nitrate was associated with a higher risk of GI cancers. Analysis suggests that nitrate concentration in drinking water was found statistically significant in predicting cancer risk with an odds ratio of 1.20.

Fifty-nine non-pregnant crossbred cows (Bos taurus indicus x Bos taurus taurus) previously selected by gynecologic examination with a body condition score (BCS) of 3.0 (scale of 1 - 5). Cows were randomly assigned to two treatments: TEB (n = 30), on day 0, an intravaginal progesterone releasing device (Primer®) was inserted and cows received i.m. 2.0 mg of estardiol benzoate (EB, Estrogin®); on day 8, the PRIMER was removed and cows received i.m. 300 IU of eCG (Novormon®) and 0.15 mg of PGF2α (Prolise®); on day 9, cows received i.m. 1 mg of EB. FTAI was carried out 48-56 hours after PRIMER removal; and TEBGnRH12 (n = 29): similar protocol to TEB, but with administration of 25 µg GnRH (Lecirelin, Gestran Plus®) on the 12th day after AI. On the 35th day after AI, diagnosis of pregnancy was performed by transrectal ultrasound. The pregnancy rate was analyzed by logistic regression. The results showed that 53.33% of the cows (16/30) in TEB and 37.93% (11/29) in TEBGnRH12 became pregnant after the first service. No significant difference was found among the pregnancy rate of animals in the treatments (P> 0.05). There was no difference between the P4 concentrations (TEB = 3.88 ng/mL and TEBGnRH12 = 3.12 ng/mL) among the heifers in the treatments (P> 0.05). The administration of GnRH analogs 12 days after TAI did not influence pregnancy rate or the progesterone concentration.

SOX4 Allows Facultative β-Cell Proliferation Through Repression of Cdkn1a
Authors: Xu Eric E. , Sasaki Shugo , Speckmann Thilo , Nian Cuilan , Lynn Francis C.
Published: May 2017

The high-mobility group box transcription factor SOX4 is the most highly expressed SOX family protein in pancreatic islets, and mutations in Sox4 are associated with an increased risk of developing type 2 diabetes. We used an inducible β-cell knockout mouse model to test the hypothesis that Sox4 is essential for the maintenance of β-cell number during the development of type 2 diabetes. Knockout of Sox4 at 6 weeks of age resulted in time-dependent worsening of glucose tolerance, impairment of insulin secretion, and diabetes by 30 weeks of age. Immunostaining revealed a decrease in β-cell mass in knockout mice that was caused by a 39% reduction in β-cell proliferation. Gene expression studies revealed that induction of the cell cycle inhibitor Cdkn1a was responsible for the decreased proliferation in the knockout animals. Altogether, this study demonstrates that SOX4 is necessary for adult β-cell replication through direct regulation of the β-cell cycle.
Power quality analysis of Gas Metal Arc Welding process operating under different drop transfer modes
Authors: E. F. da Silva  , J. R. Macedo. Jr  , A. Scotti  , J. C. de Oliveira
Published: May 2017

. This work deals with power quality analyses related to the effect of different drop transfer modes in Gas Metal Arc Welding (GMAW) processes. The different drop transfer modes of GMAW process could be classified into: short-circuiting, globular, spray and pulsed. The correct choice of GMAW parameters is essential for optimal performance of the welding process. On the other hand, optimal parameters (from the point of view of the welding process) can lead to different power quality problems on the AC side of the local electric utility, according to the desirable transfer mode. In this sense, some power quality analysis based on metering results related to voltage fluctuations, harmonics and interharmonics will be presented to investigate the relationship between power quality problems and GMAW process operating under different drop transfer modes.
Sizing stand-alone hybrid generation for seasonal irrigation pumping
Authors: Javier Carroquino  , Rodolfo Dufo-López  , José L. Bernal-Agustín
Published: May 2017

This paper studies the generation to feed three stand-alone existing pumping systems in the province of Zaragoza (Spain), in the same area but with different consumption and irrigation needs. All of them are used only for half the year. We look for the optimal size of the generation mix, both economically and in reducing emissions. For simulation and optimization the program used is HOGA (Hybrid Optimization by Genetic Algorithms). It is considered diesel generation, photovoltaic and wind as well as storage. As renewable resources are almost identical in the three locations, the magnitude of energy demand and schedule are the distinctive parameters of each facility. We considered how to choose the optimum angle of the PV array, the preference between the solar and wind and the desirability of whether or not the diesel generator. The results show the importance of seasonality and time consumption profile to determine the generation mix and to choose the optimum inclination of the field of photovoltaic conversion. Results also show that most emissions reductions are not always obtained by removing the genset.

The logical advancement of the string con-cept is the separate connection of each solar module to the grid. Therefore  module  integrated  inverters  or  multilevel-inverters can  be  used.  This  concept  has  some  advantages,  as  minimized mismatching  losses  and  minimized  DC  wiring.  But  the  circuit complexity  is  of  course  much  higher.  In  this  paper  the  layout and  implementation  of  DC/DC-converters  as  linkages  between solar modules and multilevel-inverters will be presented.

Characterization of Solar Panels for Powering Sensor Applications
Authors: M. Alves  , J.M. Dias Pereira  , J.P.S. Catalão
Published: May 2017

Devices installed in remote places require continuously energy supply for their functionality or communication requirements. For these applications, conventional energy supply is very expensive, or unreliable, and batteries dependence is not a good solution for long-term installations. Energy harvesting can be a good solution, to increase the availability of energy. Regenerative energy sources like thermoelectric, magnetic, piezoelectric, and/or renewable sources such as photovoltaic, wind, among others, allowed the development of different powering solutions for sensor units. The purpose of this work is to characterize three photovoltaic solar panels for different power consumption sensor applications. The study is carried out taking into account the intensity of light and angle of incidence over the photovoltaic panels versus voltage generated. The energy is stored in an association of supercapacitors. This association together with the solar panel itself forms the two possible sources to supply the sensor application.

Salt Stress induced changes in growth, pigments and protein contents in two horse gram [Macrotyloma uniflorum (Lam.) Verdc] varieties
Authors: C. Sathish G. Kanagaraj* and
Published: May 2017

Growth parameters and photosynthetic pigments changes in horse gram were investigated under salinity of different concentrations (0, 40, 80. 120mM). The two horse gram varieties Paiyur-2 and CO-1 were sampling was done in young and fully matured leaves were taken from control and salinity treated plants on 15th Days After Treatment (DAT) and 30th DAT. Treatments were planted in pots.  Growth parameters such as plant height, lea area, fresh and dry weight of the whole plants decreased in both varieties under salinity stressed condition. Photosynthetic pigments such as total chlorophyll, chlorophyll ‘a’ chlorophyll ‘b’ were significantly reduced in the salinity stressed leaves. Quantitative differences with response to salinity. Were also noticed in the content of soluble protein in two horse gram varieties. Our data revealed that Paiyur-2 maintained lower reduction of growth and higher contents of photosynthetic pigments as well as soluble protein content when compared to variety CO-1 during the adverse effect of salinity stress.
Pioneering a Rural Identity on the Canadian Shield: Tourism, Household Economies, and Poor Soils in Muskoka, Ontario, 1870–1900
Authors: Watson Andrew
Published: May 2017

At the end of the nineteenth century, Euro-Canadians extended rural society into new frontier areas unsuited to agriculture. These efforts were informed by a perspective that conflated rural and agrarian – a perspective that continues to dominate historians' thinking about rural societies. The resettlement of Muskoka demonstrates how the Canadian Shield's poor soils forced pioneers to rethink these assumptions and, in places adjacent to the lakes, construct a rural identity based on a tourism economy. At the same time as backwoods settlers experimented with shorter-lived opportunities in the agro-forestry economy, settlers along the lakeshore embraced the opportunities of a largely forested landscape to sell accommodation, fresh foods, and services to summer visitors. The Muskoka story therefore sheds light on the critical role that local household economies played in supporting tourism, an aspect of tourism that historians have generally ignored. Furthermore, this case study offers new insights into the role that tourism played in crystallizing a specific type of rural identity. Rather than simply serving as a replacement, supplement, or challenge to an older farming or resource extraction economy, tourism defined Muskoka's social and economic identity from the earliest stages of resettlement.
De la pertinence historiographique d'une trajectoire individuelle : Lionel Groulx, la Confédération et le Canada français
Authors: Bock Michel
Published: May 2017

À partir de la double perspective du genre biographique et de l'histoire intellectuelle, cet article a pour objectif de montrer la pertinence de l'étude du parcours de Lionel Groulx, l'un des principaux penseurs du nationalisme canadien-français des années 1910 à la Révolution tranquille des années 1960, au regard de son rapport à la Confédération canadienne. Avec Groulx, il est possible, en effet, de pénétrer le champ intellectuel canadien-français afin d'en comprendre la configuration et de mettre en perspective les facteurs qui en ont façonné l'évolution au XXe siècle. Une approche consistant à historiciser sa pensée, à la situer dans son contexte intellectuel, politique et religieux, permet aussi de comprendre les tensions internes qu'elle recèle en fonction de ses « constantes » et, surtout, des relations qu'il entretenait avec les autres acteurs du champ intellectuel et au contact desquels ses idées se sont en partie construites. En étudiant Groulx à la fois comme le produit et un critique d'un « système normatif » particulier (Giovanni Levi), l'historien évite d'essentialiser le groulxisme et de le réduire, de manière anhistorique, à une simple juxtaposition de contradictions irréductibles.
Perspectives on Cinema and Comics
Authors: Boillat Alain
Published: May 2017

This article focuses on the relatively little-known editorial context of children’s
French-language comics serials at a time when they constituted the
main distribution channel of the bande dessinée medium (before the album
became the dominant format), from the immediate post-war years to the
mid-1950s. I examine the importance given to the adaptation of films into
bande dessinée by studying the editorial strategy to which this practice of
adaptation contributes (focusing on the magazine L’Intrépide [The daredevil],
which, at the time, specialised in adaptation) and the narrative and
figurative aspects of the adapters’ approaches. I show in particular how
bandes dessinées are inscribed in genres that structure the periodical publications,
where these were previously established in the cinematographic
domain such as the swashbuckler and the western. The processes of condensation
or amplification of the narrative, as well as the use of the feuilleton,
are at the centre of the case studies.
Gazing at Medusa
Authors: Krauthaker Marion , Connolly Roy
Published: May 2017

Hélène Cixous’s liminal text ‘The Laugh of the Medusa’ calls for a challenge
of traditional representations of femininity and prompts women to inscribe
their hitherto concealed femininity into the world. Depicting the love, relationship
and loss experienced by two female characters, Julie Maroh’s 2010
Blue Is the Warmest Color provides a narrative sustained by a reclaimed
matrixial gaze that challenges patriarchal definitions of women. Whereas
the original comic book acts in concert with Cixous’s perspective and seeks
to assert the infinite richness of women’s individual constitutions, the 2013
film adaptation by Abdellatif Kechiche presents a different economy. This
article analyses how, in contrast to Maroh’s original, the filmic adaptation
discounts the feminine stance, develops a heteronormalised take on the
same story and could therefore be read as promoting heteronormative leitmotifs
and fantasised clichés of lesbian subjectivity and sexuality.
Adapting the Rhetoric of Authentication of Riad Sattouf’s La Vie secrète des jeunes
Authors: Lecomte Guillaume
Published: May 2017

The comic book series La Vie secrète des jeunes is a sardonic account of
French young people’s behaviours witnessed from the voyeuristic viewpoint
of its author-illustrator, Riad Sattouf. Despite its caricatural and non-photorealistic
visual style, the work conveys a strong sense of authenticity, mixing
truth claims borrowed from established non-fiction traditions (journalism,
autobiography and documentary). It is also a rare example of a non-fiction
comic turned into live action. This article considers the comic and its TV
adaptation, and discusses film’s ability to adapt an account of truth rooted
in comics ontology. The article first provides a theoretical structure that
details the intricacy of repeating the truth from comic to film. Second, it
highlights the way in which the comic develops its authenticity by constantly
reaffirming Sattouf’s presence and subjectivity. The article aims to show
that the adaptation anonymises this viewpoint in order to re-construct the
authenticity of its reality.
Adapting Brittany
Authors: Blin-Rolland Armelle
Published: May 2017

This article examines two bande dessinée versions of the Breton legend
of the flooded city of Ker-Is, Robert Lortac’s 1943 À la découverte de Ker-Is
(published in children’s magazine O lo lê) and Claude Auclair and Alain
Deschamps’s 1981 Bran Ruz. It argues that through the continuation or
appropriation of the legend, these comics offer ideologically filtered views
of Bretonness and Brittany from two different politico-historical contexts,
occupied France and the postcolonial era. The article also analyses how
comic art can be used in productive ways to represent Brittany as a stateless
culture, including through text-image reiteration or supplementarity,
and using the double page for a bilingual parallel textual-visual practice. It
concludes by suggesting that the study of internal colonialism and peripheries
such as Brittany is an important addition to research into postcolonial
comics.
