Les Midinettes Révolutionnaires
Authors: Fee Annie
Published: October 2017

In their quest for official and cultural recognition, French First Wave critics such as Louis Delluc discursively positioned the working-class female cinemagoer as emblematic of the sorry state of unsophisticated French film audiences. From this discourse came the stereotype of the starry-eyed midinette, which is still used by French film critics to describe lowbrow film taste and an overly emotional mode of spectatorship. This essay attempts to reconstruct the social practice of cinemagoing among the midinettes of 1920s working-class Paris by focusing on the female fans of the serial Les deux gamines (1921). Both a critique of intellectual cinephilia as a cultural discourse and a geographically specific retrieval of the multiple ways in which socioeconomically and culturally marginalized audiences interacted with the cinema, this historical study repositions young women from working-class neighborhoods as key actors in film culture—fans, but also social activists. Through a study of disparate, unpublished archival material, including fan letters, film programs, and announcements in the leftist press, this essay attends to the social realities of a number of female film fans in Montmartre and grounds their spectatorship spatially within their local communities.
“We Are Coming Out to the Light”
Authors: Norden Martin F.
Published: October 2017

Lois Weber gave many speeches during her career as a film writer-director, but until now our knowledge of them has been limited to journalistic summaries and brief quoted excerpts. The current article advances our understanding of this dimension of Weber's career (and helps restore her “voice,” in a sense) by providing the text of an entire speech, reconstructed from five primary sources. Weber discussed a wide range of film topics in this public talk, which she delivered to the Los Angeles Woman's Club in July 1913. They included censorship issues, film's educational possibilities, her interest in greater authenticity in films, and her desire to uplift films and to correct the misinformation surrounding what she called “the glamour and danger of motion picture work.” It typifies the many speeches she gave to audiences made up of women who shared her interest in raising the standards of Hollywood and its products.

In the amyloidogenic pathway associated with Alzheimer disease (AD), the amyloid precursor protein (APP) is cleaved by β‐secretase to generate a 99‐aa C‐terminal fragment (C99) that is then cleaved by γ‐secretase to generate the β‐amyloid (Aβ) found in senile plaques. In previous reports, we and others have shown that γ‐secretase activity is enriched in mitochondria‐associated endoplasmic reticulum (ER) membranes (MAM) and that ER–mitochondrial connectivity and MAM function are upregulated in AD. We now show that C99, in addition to its localization in endosomes, can also be found in MAM, where it is normally processed rapidly by γ‐secretase. In cell models of AD, however, the concentration of unprocessed C99 increases in MAM regions, resulting in elevated sphingolipid turnover and an altered lipid composition of both MAM and mitochondrial membranes. In turn, this change in mitochondrial membrane composition interferes with the proper assembly and activity of mitochondrial respiratory supercomplexes, thereby likely contributing to the bioenergetic defects characteristic of AD.
The effect of atorvastatin on pancreatic beta cell requirement in women with polycystic ovary syndrome
Authors: Sathyapalan Thozhukat , Coady Anne-Marie , Kilpatrick Eric S , Atkin Stephen L
Published: October 2017

Background

There is an increased risk of developing T2DM in women with polycystic ovary syndrome (PCOS), and there is evidence that statins improve metabolic parameters in these patients. However, there are some data to show that statins increase the risk of incipient diabetes.

Materials and methods

We have previously shown that 12 weeks of atorvastatin improves insulin resistance when measured using HOMA-IR. This post hoc analysis was designed to look at the effect of atorvastatin on pancreatic β cell function using HOMA-β in the same study. In this randomised, double-blind placebo controlled study, 40 medication-naïve patients with PCOS were randomised to either atorvastatin 20 mg daily or placebo for 3 months. A 3-month extension study for both groups of patients was undertaken with metformin 1500 mg daily after completing initial 3 months of atorvastatin or placebo.

Results

There was a significant reduction in HOMA-β (240 ± 3.2 vs 177 ± 2.3; P value <0.01) after 12 weeks of atorvastatin treatment, which was maintained by metformin in the subsequent 12 weeks. There were no changes in HOMA-β after the placebo or after subsequent metformin treatment.

There was no linear correlation between reduction in HOMA-β with improvement of free androgen index (FAI) (r2 = 0.02; P = 0.72), testosterone (r2 = 0.13; P = 0.49), SHBG (r2 = 0.22; P = 0.48), hsCRP (r2 = 0.19; P = 0.64), triglycerides (r2 = 0.09; P = 0.12), total cholesterol (r2 = 0.11; P = 0.32) or LDL-C (r2 = 0.19; P = 0.38).

Conclusion

Treatment with atorvastatin for 12 weeks in women with PCOS significantly reduced HOMA-β. This could be potentially due to fall in β-cell requirement with improvement of insulin resistance rather than a reduction of β-cell function.
Customization of B2B Services: Measurement and Impact on Firm Performance
Authors: Kleinaltenkamp Michael , Minculescu Ioana , Raithel Sascha
Published: October 2017

Customization of services comprises the activities and results of a customer-specific adaptation of a provider’s value-creation processes according to customers’ requirements. As customized service offerings are supposed to better meet specific customers’ needs, they should generate a higher willingness to pay and/or higher customer loyalty. However, customization also typically leads to increased costs, incurred from the customer-induced changes or adjustments in the specification, production and delivery of a service. With respect to this tradeoff, this paper examines how the degree of customization of business-to-business (B2B) services can be measured and how the degree of customization affects the generation of competitive advantages and firm performance. Using data from a large-scale quantitative study, the paper identifies three dimensions of customization of B2B services and shows the consequences of different degrees of customization on customer perceived value, cost-efficiency and thus firm performance.
Topics for Service Management Research - A European Perspective
Authors: Benkenstein Martin , Bruhn Manfred , Büttgen Marion , Hipp Christiane , Matzner Martin , Nerdinger Friedemann W.
Published: October 2017

The interdisciplinary and cross-functional commitment of the Journal of Service Management Research motivated us to define interdisciplinary topics of service research that are important both in the present and in the future. Therefore, relevant publications in this research field were examined, especially Ostrom et al. (2010, 2015), which comprehensively addressed and collated research priorities. With that in mind, issues of 48 highly ranked service-oriented management and marketing journals from 2009 to 2015 were analysed to identify research topics of the recent past. Additionally, European scientists were interviewed on their focus in the field of service research in the previous year. The results demonstrate the vast array of management-oriented service research in Europe, but also the necessity of interdisciplinary research designs in service management.

Development of quantitative HPTLC–Densitometry methods for the analysis of amiodarone HCl, carvedilol, doxylamine succinate, magnesium salicylate, metoprolol succinate, nebivolol HCl, and salicylamide using a model process developed earlier for the transfer of TLC screening methods
Authors: Nguyen K. , Sherma J.
Published: October 2017

A model process, previously developed in a series of studies, allows for the transfer of thin-layer chromatography (TLC) methods for qualitative screening of counterfeit drug products published in the Global Pharma Health Fund (GPHF) Minilab manual and US Food and Drug Administration (FDA) Compendium of Unofficial Methods for Screening of Pharmaceuticals by TLC to quantitative high-performance TLC (HPTLC)–densitometry methods. This article describes HPTLC–densitometry methods developed and validated according to this model process for pharmaceutical products of amiodarone HCl, carvedilol, doxylamine succinate, magnesium salicylate, metoprolol succinate, nebivolol HCl, and salicylamide, for which qualitative screening methods have not been published in the Minilab manual or FDA Compendium. These methods use relatively inexpensive and nontoxic “green solvents” for sample and standard solution and mobile phase preparation, Merck Premium Purity silica gel 60 F254 plates, automated standard and sample solution bandwise application, and automated densitometry for the assessment of peak purity and identity and quantification. Corresponding to the quantitative HPTLC–densitometry methods, qualitative TLC screening methods for these drug products were developed and posted online with open access as supplements to the FDA Compendium.

Published: October 2017

A reliable isotope dilution method for the determination of chloramphenicol (CAP) in drinking water was developed by using an evaporation preparative step. Each sample was monitored by ultrahigh-pressure liquid chromatography (UHPLC) coupled to tandem mass spectrometry (MS/MS) using an electrospray ionization interface (ESI) in negative ion modes. Recoveries of spiked samples were in the range from 93.2% to 95.7% with intra-day relative standard deviation lower than 6.7% and inter-day relative standard deviation lower than 8.2%. Limit of quantification (LOD) was 0.002 ng/mL. The developed method was successfully applied to the analysis of CAP in drinking water of Shannan region of Tibet.
Practical tips for bedside teaching of infectious diseases practice to junior doctors
Authors: Mucheli Sharavan Sadasiv , Archuleta Sophia
Published: October 2017

This article was migrated. The article was marked as recommended. Infectious diseases, being a cognitive specialty, is commonly perceived to be difficult to teach at the bedside. Most junior doctors have had variable amounts of exposure to infectious diseases as medical students, primarily in the form of lectures as part of a microbiology curriculum. Teaching principles of infectious diseases practice to junior doctors is essential to develop good antibiotic prescribing skills. We suggest a practical guide with 3 x 3 steps to teach infectious disease practice at the bedside. We have attempted to outline the anticipated problems with the instruction of Infectious disease practice in the clinical setting and then have proceeded to adopt an expanded version of the clinical micro-skills model to address those gaps.
Violência Juvenil e Medidas Socioeducativas: Revisão de Literatura
Authors: Moreira Jacqueline de Oliveira , Guerra Andréa Maris Campos , Drawin Carlos Roberto
Published: October 2017

RESUMO Neste artigo, partindo do objetivo de compreender a relação entre violência juvenil e a resposta do Estado através das medidas socioeducativas, buscamos explicitar o pano de fundo das pesquisas científicas atuais. Realizamos uma meta-análise dos artigos publicados sobre adolescência e medidas socioeducativas, no campo da psicologia, entre os anos de 2000 e 2012. Concluímos que essa produção nacional pode ser reunida em três grandes categorias: (a) prático-experiencial, que apresenta relatos analíticos da prática na aplicação das medidas socioeducativas, privilegiando a experiência concreta; (b) político-institucional, que discute criticamente a dimensão política da lógica socioeducativa, detendo-se na análise estrutural de sua legislação e de suas instituições; (c) sociocultural, que analisa os determinantes sociais e psíquicos do fenômeno da violência juvenil.
Aglomerações produtivas e escolha de modal de transporte: um estudo de caso do setor industrial de São Paulo e Manaus
Authors: Catela Eva Yamila da Silva , Seabra Fernando
Published: October 2017

Resumo: O objetivo deste estudo é evidenciar a complementaridade entre duas aglomerações produtivas (microrregiões de São Paulo e Manaus) e discutir a escolha do modal de transporte entre essas duas regiões. São Paulo caracteriza-se como uma aglomeração produtiva madura e diversificada; enquanto Manaus detém uma forte especialização. A partir de uma matriz de proximidade, pode-se afirmar que as microrregiões apresentam estruturas de produção complementárias. Quanto à estrutura de transportes, o comércio ocorre principalmente via modal rodo-fluvial e, em menor parte, via cabotagem. O potencial de migração para cabotagem é avaliado por uma pesquisa de escolha discreta. Os resultados indicam que esta transferência depende de características da condição de transporte (fretes, transit time, confiabilidade e regularidade do serviço) e da estrutura produtiva (como valor agregado do produto e tamanho da empresa).
Análise do conteúdo tecnológico das exportações brasileiras sob a lógica estruturalista-kaldoriana
Authors: Cabral Joilson de Assis , Cabral Maria Viviana de Freitas , Oliveira Daniel Ribeiro de
Published: October 2017

Resumo: Este estudo analisou o conteúdo tecnológico das exportações brasileiras para verificar se a expansão das exportações ocorrida entre 2000 e 2005 seria capaz de induzir o crescimento econômico sustentado seguindo a lógica estruturalista-kaldoriana. Para tanto, foram utilizadas as matrizes de insumo-produto disponibilizadas pelo IBGE, compatibilizadas com base na taxonomia proposta por Lall (2000). Os resultados do estudo mostram que, apesar da melhora do resultado comercial do país verificada no período analisado, o aumento das exportações brasileiras não seria capaz de induzir um círculo virtuoso de crescimento econômico sustentado. Sob a lógica estruturalista-kaldoriana, esse fato pode ser creditado à concentração da expansão das exportações nos setores de baixo conteúdo tecnológico que, no longo prazo, não causaria a ruptura da restrição externa ao crescimento econômico do país. Essa constatação sugere que o Sistema Nacional de Inovação brasileiro ainda apresenta um baixo grau de desenvolvimento com papel limitado na indução da atividade econômica.
Trabalho, globalização e contramovimentos: dinâmicas da ação coletiva do precariado artístico no Brasil e em Portugal
Authors: Braga Ruy , Marques Joana
Published: October 2017

Resumo O artigo pretende comparar a formação do “precariado artístico” no Brasil e em Portugal, a partir da análise dos padrões de proletarização do trabalho de produção cultural nos dois países e sua relação com diferentes trajetórias de ação coletiva dos novos movimentos de trabalhadores precarizados. Assim, destacaremos o dilema enfrentado pelo movimento dos trabalhadores precários para transnacionalizar suas formas de ação coletiva. No caso brasileiro, analisamos, especificamente, a mobilização por políticas públicas para a cultura empreendida pelo movimento “Arte contra a Barbárie” que, distante do sindicalismo, desembocou na conquista do programa paulistano de Fomento ao Teatro. No caso português, investigamos a ação coletiva que se consolidou com a criação do sindicato-movimento “Cena” contra a perda de direitos trabalhistas, num contexto marcado pela adoção pelo governo português de políticas de austeridade negociadas com a União Europeia. Os limites da transnacionalização das reivindicações desses grupos de trabalhadores precários serão problematizados à luz da ideia, muito presente nos novos estudos “neopolanyianos” do trabalho, de que o processo de mobilização do precariado no Sul global anunciaria o advento de um contramovimento “embrionário”, cuja tendência seria florescer conforme a mercantilização neoliberal ampliasse as ameaças à classe trabalhadora em escala mundial.
Os acordos-marco internacionais e as alianças sindicais internacionais: instrumentos de uma necessária transnacionalização da militância sindical
Authors: Hennebert Marc-Antonin
Published: October 2017

Resumo Diante da multiplicação atual dos instrumentos de responsabilidade social empresarial (RSE), o dispositivo frequentemente considerado mais avançado em matéria de defesa dos direitos dos trabalhadores consiste na negociação e na assinatura de acordos-marco internacionais (AMIs). Esses acordos, assinados conjuntamente por uma federação sindical internacional e pela direção de uma empresa multinacional, buscam garantir o reconhecimento de certos direitos sociais fundamentais em todas as operações de uma empresa em âmbito internacional. Baseado na análise dos casos de duas empresas norte-americanas que ratificaram AMIs, este artigo procura evidenciar a contribuição desse instrumento para a regulação social das multinacionais e esclarecer as condições de sua efetividade, assim como seus limites. Ambos os casos demonstram que a utilidade desses acordos repousa, acima de tudo, no modo como os atores sindicais se apropriam desse instrumento. Por fim, nosso estudo salienta a importância das alianças ou coalizões internacionais entre os representantes sindicais de uma mesma multinacional para acompanhar os acordos e lhes dar um sentido prático em sua realidade local.
Soccer (Football Association) and chronic traumatic encephalopathy: A short review and recommendation
Authors: Nitrini Ricardo
Published: October 2017

ABSTRACT Chronic traumatic encephalopathy (CTE) was initially described in boxers, but in recent years it has been reported in other settings, particularly in contact sports and military personnel. Soccer (football association) had previously been (and still is) considered relatively safe when compared to other sports, such as American football. However, a few cases of professional soccer players with CTE have been reported in the last few years. It is still unknown how frequent this condition is in soccer players, and the role played by heading the ball remains elusive. Other traumas to the head, face and neck caused by contact with another player's head, arm or other body parts are among the most frequent in soccer. In spite of the lack of more in-depth knowledge, there is reasonable evidence for recommending severe punishment (red card and suspension for several matches) for players causing avoidable trauma to another player's head.

ABSTRACT Cognitive impairment and dementia commonly occur in individuals with chronic kidney disease, especially in advanced stages, but are still poorly diagnosed. OBJECTIVE: To evaluate the cognitive ability of patients with chronic kidney disease on hemodialysis and its relationship with sociodemographic and clinical characteristics. METHODS: A cross-sectional study was carried out in a Renal Replacement Therapy Unit in the interior of the State of São Paulo involving 99 patients. The data were collected through an individual interview, using the Sociodemographic and Clinical Characterization questionnaires and the Addenbrooke's Cognitive Examination – Revised (ACE-R) questionnaire. RESULTS: Participants were predominantly male, with a mean age of 54.68 years. The mean ACE-R score was 64.26 points, and 76.76% of patients had lower-than-expected scores, suggesting the presence of cognitive impairment. A moderate, negative correlation was found between total score on the ACE-R and age (r= –0.38, p≤0.001), a moderate positive correlation with years of education (r=0.52, p≤0.001), and a weak positive correlation of total score with hemodialysis time (r=0.26, p≤0.001). CONCLUSION: A relationship was found between cognitive ability and age, years of education and hemodialysis time, suggesting that individuals who were older, had less education and longer hemodialysis time presented greater cognitive impairment.
Singularidades museológicas de uma tábua com esculturas em diálogo: do alambamento ao casamento em Cabinda (Angola)
Authors: Martins Maria do Rosário Antunes Rodrigues , Tavares Ana Cristina Pessoa
Published: October 2017

RESUMO Em Cabinda (noroeste de Angola), uma região do antigo Reino do Congo, existiu uma ancestral tradição gráfica observada em artefatos do cotidiano ou rituais que tem sido objeto de pesquisas em domínios multidisciplinares. O presente artigo remete para uma das possíveis reflexões em torno de uma tábua frustemente esculpida em alto-relevo, de que se desconhecem outros espécimes, e que integra a coleção recolhida pelos Missionários do Espírito Santo, atualmente em depósito no Museu da Ciência da Universidade de Coimbra. Não foi o valor estético que nos seduziu mas sim entender o seu significado, provocação que encontrou resposta na obra de José Martins Vaz, No mundo dos Cabindas, único suporte encontrado, até à data, que divulga a interpretação gráfica da peça e descodifica os motivos escultóricos. Esse objeto reflete um acordo de casamento e corporiza ideias, expressas por formas gravadas e símbolos, detentores de saberes tradicionais, intrinsecamente associados ao riquíssimo acervo da cultura material, incluindo a caixa nkobe-bingu, divindade protetora da família. Portadora de um significado singular, a tábua ou dístico de casamento espelha a dificuldade de acordo entre as famílias dos noivos quanto ao alambamento a negociar e sela o tradicional contrato de matrimónio dos Cabinda, etnia aparentada com o povo Kongo. Não sendo possível comparar com outras interpretações, o estudo desenvolvido permitirá compreender melhor o universo espiritual Cabinda refletido nas suas criações artísticas. Alargando horizontes de pesquisa, a tábua proporcionou um exercício museológico para o entendimento da realidade social da sua génese e de rituais de casamento de outros povos, em várias épocas.
Migração makonde, produção de esculturas e mercado de arte no Tanganyika: a questão do estilo Shetani (1950-60)
Authors: Laranjeira Lia Dias
Published: October 2017

RESUMO O presente artigo incide sobre parte da minha pesquisa de doutorado que teve como foco a produção de arte makonde em diálogo com a história política de Moçambique entre 1950 e 1974. A investigação de caráter interdisciplinar envolveu fontes de naturezas diversas, como a documentação produzida no período colonial, assim como uma bibliografia acessada em diferentes acervos de Lisboa e na Biblioteca do Museu Etnológico de Berlim, além de relatos orais coletados em Moçambique entre 2012 e 2014. Essas fontes orais foram produzidas, especialmente, em entrevistas e conversas com escultores, os quais denominam suas respectivas peças como arte makonde. O presente texto discute o contexto de produção de um estilo de escultura específico conhecido como shetani, que foi criado no território vizinho do Tanganyika (atual Tanzânia), no final da década de 1950, por Samaki Likonkoa, artista makonde de Moçambique. Analiso aqui a referida produção no âmbito da vivência migratória internacional dos makonde de Moçambique para o Tanganyika, motivada pela busca por melhores condições de trabalho e de vida. O caso da produção desse tipo de escultura ilustra, aqui, a circulação de pessoas, objetos e conhecimento entre o sul e o norte do rio Rovuma no contexto colonial português das décadas de 1950 e 1960.
Padrões de mudança técnica nas economias latino-americanas: 1963-2008

Published: October 2017

Resumo O presente artigo emprega a relação de distribuição-crescimento para descrever os padrões de progresso técnico das economias latino-americanas no período 1963-2008. A relação de distribuição-crescimento possibilita visualizar a mudança técnica ao longo do tempo. A análise revelou a predominância do padrão de progresso técnico Marx-viesado e poupador de insumos com aumento da relação capital-trabalho no período como um todo. Também se verificou um processo de desmecanização em dois países e retrocesso do progresso técnico em outros dois países. Contudo, houve três fases na evolução do progresso técnico na América Latina, 1963-1980, 1980-2000 e 2000-2008. O padrão Marx-viesado foi predominante na primeira fase, houve regresso técnico na segunda fase, enquanto na terceira fase o padrão mais observado foi o poupador de insumos com aumento da intensidade de capital.

Published: October 2017

RESUMO O trabalho foi desenvolvido em uma área de pasto abandonada revegetada com leguminosas arbóreas. Localizada no município de Valença, RJ, nela foram utilizadas diferentes proporções de leguminosas arbóreas fixadoras de nitrogênio: 0% (0L), 25% (25L), 50% (50L) e 75% (75L). Para avaliação da macrofauna do solo, as amostragens foram feitas nas épocas seca e úmida, utilizando-se o método TSBF. Outras amostragens foram realizadas, ainda, em uma floresta secundária (FS) e em duas áreas de pasto (PA e PB). O processo de revegetação aumentou a diversidade da fauna do solo de uma forma geral. Formicidae foi o grupo da macrofauna de maior abundância em todas as áreas, para as duas épocas de avaliação. Na época chuvosa, houve aumento considerável na quantidade de invertebrados na camada serapilheira nos tratamentos 0L, 25L, 50L, 75L e Floresta Secundária, o que no período seco aconteceu na camada 0-10 cm.

ABSTRACT Objective: To evaluate the efficacy of acute chiropractic adjustment in individuals who practice CrossFit with regard to complaints of low back pain and the joint range of motion in this region. Methods: A randomized clinical trial comprised of CrossFit practitioners from a box in Novo Hamburgo-RS, of both sexes and aged 18 to 40 years who had low back pain at the time of the study. The following tools were used: Semi-structured Anamnesis Questionnaire, Visual Analog Scale, McGill Pain Questionnaire, and SF-36 Quality of Life Questionnaire. Individuals in the control group answered the questionnaires before and after CrossFit training. The chiropractic group performed the same procedure, plus pre-training chiropractic adjustment and joint range of motion (ROM) before and after lumbar adjustment. Results: There was a significant increase in pain in the control group, and a significant decrease in pain in the chiropractic group, including one day after the chiropractic adjustment. In the chiropractic group, the joint ranges of motion had a significant increase in flexion and extension of the lumbar spine after chiropractic adjustment. Conclusion: The chiropractic group achieved a significant improvement in pain level and joint range of motion, suggesting that acute chiropractic adjustment was effective in reducing low back pain.
LANGERHANS CELL HISTIOCYTOSIS OF THE SCAPULA - DIAGNOSIS & TREATMENT OPTIONS
Authors: PANDEY ROHIT , BHAYANA HIMANSHU , RAJNEESH RAJESH KUMAR , DHAMMI ISH KUMAR , UL-HAQ REHAN , JAIN ANIL KUMAR
Published: October 2017

ABSTRACT Langerhans cell histiocytosis (LCH) is characterised by an abnormal histiocytic accumulation in tissues such as the lung, spleen, bone marrow, skin, central nervous system, liver and lymph nodes, causing focal or systemic effects. No specific clinical & radiographic presentation of LCH is described in literature. This poses a diagnostic dilemma for surgeons. The scapula is the site of 3% of bone tumours, while for LCH it is the least common site. In a 10-year-old boy with isolated lesion of the scapula with no other systemic involvement, and no specific finding in MRI or CT scan of scapula, diagnosis was confirmed on biopsy. Division into single and multi-system disease is paramount in treatment, given that it is a single system disease. The patient improved clinically on follow-up of 2 years. The scapula is one of the rarest site of LCH, and because various lesions mimic each other, a biopsy is always required, with immunohistochemistry for CD68 & S-100. This was only a single system disease, so conservative management was performed, and the patent improved clinically.

Published: October 2017

ABSTRACT Objective: To analyze the epidemiological profile of patients with spinal fractures and the characteristics of the population at risk attended at a university hospital. Methods: The study population is composed of 202 patients diagnosed and treated for vertebral fracture due to trauma. The variables were correlated with each other and the correlations with p<0.05 were considered statistically significant. Results: The ratio of incidence of trauma between the sexes was 3:1 for males. The mean age was 37 years and the age group with the highest incidence was between 20 and 39 years. Traffic accidents were the most frequent mechanism (51.2%) and secondly, falls (33.2%). There was a statistical correlation between trauma mechanisms to age group and region of the spine. The first lumbar vertebra (L1) fracture alone accounted for 21.5% of all cases studied associated with the fall mechanism. Spinal cord injury was recorded in 33.7% of the individuals in the sample. A total of 57.3% of the patients were submitted to surgical treatment and 41.7% to the conservative treatment. The mean hospitalization time was 15 days. Conclusions: Spinal fractures are important determinants of morbidity and mortality in the population with a major impact on economically active individuals, especially males. They are directly associated to traffic accidents in the young population and to falls in the higher age brackets. Primary prevention of trauma is the main mechanism for change in this scenario.

Authors: Cuevas Mestanza Paulo Enrique , Rodrigues Ávila Veridiana De Melo
Published: October 2017

A Bioquímica é uma ciência complexa que estuda as biomoléculas e suas interações nas vias metabólicas nos seres vivos. Devido a um extenso conteúdo em contraposição ao curto período para ministrá-la, somente aulas expositivas tornam-se insuficientes para despertar o interesse nos estudantes e resolver dúvidas. Nessa perspectiva, é muito importante desenvolver novas ferramentas educacionais para melhorar a compreensão destes conteúdos. “Quem é o carboidrato?” É um jogo didático criado para revisar a relação estrutura e função de carboidratos. Baseado no clássico “Cara a cara” O objetivo do jogador ou grupo é descobrir primeiro o nome do carboidrato do adversário.
Individualism and memory: Robert Frost and Tanure Ojaide
Authors: Orhero Mathias Iroro
Published: October 2017

This article examines individualism and memory in Robert Frost's A boy's will (1913) and Tanure Ojaide's The beauty I have seen (2010). The paper adopts existentialism as a critical approach. Previous studies on these poets, especially Ojaide, have neglected the individualistic nature of their poetry and stereotyped the poets. This article, thus, brings a new approach to the critical debates and scholarship on these poets. The aim of the article is to show the individualistic and existentialist nature of the poetry of Frost and Ojaide. In the analysis, individualism is examined at the level of form and content; starting with the use of the lyric form and poet-persona inclusion in the poems to the thematisation of gloom and the importance of memory, among others. The paper shows that, truly, these poets are largely individualistic in outlook, and they have expressed existentialist philosophy in their poetry.

Diet-induced obesity by administration of a western-type diet high in fat and sugar to mice may result in an elevation of plasma total and LDL-cholesterol levels, triglycerides and the levels of the liver enzymes alkaline phosphatases and aspartate (AST)andalanine aminotransferases (ALT).
Hematoxylin and eosin staining of murine adipose and liver tissues v1
Authors: Hemmeryckx Bianca , Bauters Dries , Roger Lijnen H.
Published: October 2017

Diet-induced obesity through administration of a western-type diet high in fat and sugar to mice can result in a higher weight of adipose and liver tissues. The increased adipose tissue weight can be due to hypertrophy (bigger cells) or hyperplasia (more cells) of adipocytes, or a combination of both. Hematoxylin and eosin (H&E) staining of adipose tissue sections allows you to investigate the size of the individual adipocytes. A western-type diet can induce accumulation of fat (= steatosis) in the liver, which is nicely illustrated by an H&E stain.

Sirius Red staining is a usefull stainingto studycollagendistribution. In adipose tissue development during obesity the extracellular matrix is being remodeled and this can be analyzed using Sirius Red staining. In addition, fibrosis in livers from mice suffering from non-alcoholic steatohepatitis can be identified using this staining. Moreover, scar formation after the induction of a myocardial infarct can be illustrated using the Sirius Red staining.
Modern Psychological Models Of Suicidal Behavior In Adolescents
Authors: Syrokvashina K.V.
Published: October 2017

In the paper, we analyze the main psychological approaches to suicidal behavior, including those applied to adolescent suicides. The models that emphasize the factors that play a significant role in the transition from suicidal thoughts to a potentially lethal suicidal attempt (interpersonal theory, integrative motivational-volitional model, three-step theory) are highlighted. Studies conducted among adolescents on the basis of psychological models of suicidal behavior are presented. The main specific features of modern models of suicidal behavior are indicated.
Marked By Maternal Depression: The Images Of The Mother In The Therapy Of An Elementary School Child
Authors: Fedunina N.Y.
Published: October 2017

The paper deals with the issue of the influence chronic depression in the mother exercises on the psychological functioning of the elementary school child. Despite the fact that parental depression, especially in mothers, is a risk factor for social and psychological disorders in children, most studies focus on postpartum depression. We give an example of social withdrawal and peer rejection in a case of a 9-year-old boy who goes through analytic therapy. The images of his relationship with his mother which emerge during sandplay therapy expose his attitude towards the world as an unpredictable, and deadly dangerous place. The dynamics of sand pictures reveals the importance of maternal object and its vital place in the inner world of a child in comparison with other social objects, and gradual changes for a picture of a more understandable and predictable world to deal with.

Revised Predictive Model for Successful Introduction of Native Ohio Brook Trout (Salvelinus fontinalis) in Select Streams in Geauga and Lake Counties, Ohio a
Authors: Amey Katherine Springer
Published: October 2017

Eight cold-water streams in Lake and Geauga Counties, Ohio were evaluated to develop a revised predictive model to assess future streams for the introduction of threatened native Ohio Brook Trout (Salvelinus fontinalis).  A 15-month study was conducted, ending May 2010, in streams where Brook Trout were previously introduced during the years 1997-2002.  Fifty percent of the sixteen original reintroduction streams failed to support the establishment of self-sustaining populations of Brook Trout, indicating there were additional factors contributing to their success and failure.  Of the 8 streams included in this study, 4 streams were designated successful, 2 variable, and 2 failed, in terms of the Brook Trout’s ability to establish self-sustaining populations by the Ohio Department of Natural Resources (ODNR).  Multivariate statistical methods including Principal Component Analysis (PCA) and Agglomerative Hierarchical Cluster Analysis (AHCA) were implemented to determine the most important characteristics in Brook Trout stream selection.  Factors found to be significant for Brook Trout success were stream velocities within the range of 1.4-4.7 cm/s, high hydraulic conductivity of the headwater bedrock aquifer (K>4.7 x 103 cm/s), lighter average δ18O ‰ (-9.8 to -10.4), either high percent canopy cover (40%-55%) or high percent instream cover (18%-37%), a high number of cold-water adapted benthic macroinvertebrate cold-water taxa (10-16 species), yearly average hyporheic water temperature of 4.6°C-17.2°C, average surface water turbidity of 7 to 31 NTU and long-term surface water temperature and dissolved oxygen monitoring over both winter and summer seasons is recommended prior to Brook Trout introduction to ensure their sustainability.

Published: October 2017

Total length and standard length (mm) were compared to weight (mg) in the Emerald Shiner (Notropis atherinoides - Rafinesque, 1818) in the western basin of Lake Erie. Length and weight relationship (n = 400), length-frequency distribution, and sex ratios were evaluated for  coastal and tributary habitats and compared to open water habitats. A strong positive correlation was observed between length and weight for both males and females. For males (n = 195) there was a significant positive relationship between standard length (SL) and weight (F = 935.64, d.f = 195; R2 = 0.989) and between total length (TL) and weight (F = 918.75, d.f. = 195; R2 = 0.991). In females (n = 205), there was also a strong positive correlation between SL and weight (F = 1108.18, d.f. = 204; R2 = 0.976) and between TL and weight (F = 1208.86, d.f. = 204; R2 = 0.983). This same positive relationship between SL and weight (F = 1909.58, d.f. = 399; R2 = 0.984,) and between TL and weight (F = 1960.07, d.f. = 399; R2 = 0.988) that was found for  the individual sexes was present in the combined data for the two sexes. Length-weight relationship patterns in Emerald Shiner were significantly influenced by sex (ANCOVA, F= 313.03, p < 0.01) and habitat (ANCOVA, F = 6.693, p = 0.013).  Three separate age classes were distinguished in the data. Age 0 males ranged from 15-33 mm TL, while age 0 females ranged from 18-30 mm TL. Age I males ranged from 39-78 mm TL and Age I females ranged from 42-78 mm TL. Age II+ males ranged from 78-111 mm TL and Age II+ females ranged from 81-108 mm TL. Emerald Shiner exhibit indeterminate growth and sex influenced growth patterns based on the von Bertalanffy growth model.

The effects of socializing and environmental enrichments on sow and piglet behavior and performance
Authors: Ledergerber Karlie , Bennett Benjamin , Diefenbacher Nicole , Shilling Crystal , Whitaker Brian D
Published: October 2017

This study was conducted to, 1) determine the effects of socializing piglets prior to weaning on piglet behavior and performance and sow behavior, and 2) determine the effects of socializing piglets prior to weaning and inclusion of pen enrichment on nursery pig behavior and performance. Socialized piglets spent a shorter amount of time lying down during the first 24 hours following barrier removal compared to all other times and exhibited an increase in agonistic behavior. Sows had higher levels of cortisol and spent less time lying down during the first 48 hours after piglet socialization compared to all other times. In the nursery, piglets that were socialized prior to weaning had higher average daily gain (ADG) (0.48 ± 0.02 kg) and lower occurrence of agonistic behavior (30.0 ± 2.5 percent) during the first six hours after weaning compared to those piglets that were not socialized prior to weaning (0.39 ± 0.03 kg and 85.0 ± 3.5 percent, respectively). Pens with environmental enrichment contained fewer piglets displaying agonistic behavior compared to pens without environmental enrichment during the first 12 hours after weaning. The results of this study suggest that socializing piglets from different litters prior to weaning leads to temporary stress in lactating sows and an increase in agonistic behavior in piglets, but improves their performance after weaning. Inclusion of environmental enrichment in the nursery is an effective means to reduce agonistic behavior between piglets.
