Comercio Tradicional Versus Comércio Eletrônico: Um Estudo de Caso Sob o Olhar da Gestão dos Custos Logísticos
Authors: Souza Marcos Antônio de , Lemos Lindones Bisuti , Zorzo Lucas Seffrin
Published: October 2017

O objetivo do artigo é verificar como uma empresa brasileira de grande porte do setor varejista efetua a mensuração e análise dos custos logísticos tanto das suas operações físicas (comércio tradicional) quanto das suas operações virtuais (comércio eletrônico). A pesquisa é desenvolvida no âmbito das contribuições da gestão estratégica de custos para a sustentabilidade dos negócios. Trata-se de um estudo de caso único, descritivo e com abordagem qualitativa, realizado no 2o semestre de 2013. Os dados foram coletados mediante entrevistas, análise documental e observações in loco. As análises dos dados ocorreram por interpretações comparativas. Os principais resultados apontaram que não existem diferenças significativas na análise e mensuração de custos logísticos entre as duas formas de comercialização. Isso pode ser explicado, em parte, pelo fato de que a empresa não trata o comércio eletrônico de forma diferenciada em relação a gestão dos custos logísticos. Ou seja, tanto as operações da loja virtual quanto as operações das lojas físicas compartilham da mesma estrutura logística. Custos logísticos adicionais no comercio eletrônico são compensados pela maior margem praticada nesse modelo de negócios.

Published: October 2017

Este artigo apresenta os resultados de uma pesquisa que visou desenvolver uma análise financeira de uma amostra de hospitais brasileiros no período de 2006 a 2011. Os dados da pesquisa foram obtidos por meio das demonstrações contábeis de 23 hospitais e no Cadastro Nacional dos Estabelecimentos de Saúde (CNES). Esses dados secundários foram analisados por meio das seguintes técnicas: estatística descritiva, coeficiente de correlação de Spearman, teste de Kolmogorov-Smirnov, teste de Kruskal-Wallis e teste do Qui-quadrado. Em geral, constatou-se que a amostra representa resultados pouco satisfatórios, especialmente os indicadores econômico-financeiros de lucratividade e rentabilidade. Todavia, ao se analisar os hospitais com base em diferentes categorias, constataram-se importantes diferenças entre as organizações, especialmente significativas no que se relaciona à natureza dos hospitais: públicos e com fins lucrativos. Esses últimos apresentaram uma maior liquidez, além de melhores indicadores de lucratividade e uma estrutura de capital com foco no financiamento com capital de terceiros de longo prazo. Essas evidências sugerem que tais organizações se fundamentam na alavancagem financeira para obter melhores resultados sem comprometer a sua liquidez. Por outro lado, os hospitais públicos apresentaram baixa liquidez e indicadores de lucratividade e rentabilidade inferiores. Foram obtidas também evidências de que os hospitais de maior porte possuem indicadores de liquidez, lucratividade e indicadores de rentabilidade bastante inferiores aos de menor porte.
Fatores que Explicam a Divulgação Voluntária das 100 Empresas com Ações Mais Negociadas na BM&FBOVESPA
Authors: Rufino Maria Audenôra , Monte Paulo Aguiar do
Published: October 2017

A evidenciação das empresas pode assumir duas perspectivas, a divulgação obrigatória e voluntária. Normalmente, a evidenciação obrigatória imprime um padrão de divulgação, mas quando se trata de divulgação voluntária, essa envolve a natureza endógena da empresa e que, portanto, depende do julgamento dos gestores pela divulgação ou não de determinando item. Sendo assim, este estudo analisou os fatores determinantes do nível de divulgação de informação voluntária das empresas, tendo com base de cálculo a adaptação da métrica de Murcia e Santos (2009). As informações foram obtidas através das Demonstrações Financeiras Padronizadas publicadas no site da BM&FBOVESPA, relativas ao exercício findo em 2012. Fundamentando-se pela Teoria da Divulgação Voluntária construíram-se sete hipóteses que foram testadas através do modelo de regressão linear múltipla, tendo como variável a ser explicada o Índice de Divulgação Voluntária (IDV) e como variáveis explicativas a Rentabilidade (ROE), Sustentabilidade (ISE), Tamanho (TAM), Endividamento (END), Concentração Acionária (CON), Internacionalização (INT) e Empresas Regulamentadas (REG). Os resultados apontam que a rentabilidade, o tamanho das empresas e a sustentabilidade são fatores determinantes da divulgação voluntária, sendo portanto, positivamente significativas nos modelos estimados. Consequentemente, concluiu-se que quatro das hipóteses testadas não possuem comprovação empírica, são elas: endividamento, concentração acionária, internacionalização e empresas regulamentadas.

Authors: Richartz Fernando , Borgert Altair , Ensslin Sandra Rolin
Published: October 2017

Este artigo objetiva a realização de um mapeamento das pesquisas científicas sobre comportamento dos custos para a identificação do seu atual panorama. Por meio de pesquisas em bases de dados obteve-se a seleção de um portfólio bibliográfico (PB) relevante, o qual resultou em 29 artigos, de acordo com os critérios definidos na pesquisa. Destes, tem-se o artigo de Anderson, Banker e Janakiraman (2003) como destaque do portfólio. Além disso, Banker é considerado o principal autor sobre comportamento dos custos, cuja representatividade se evidencia tanto no PB quanto em suas referências. O principal periódico, tanto pelo fator de impacto quanto pelo número de artigos publicados, é o The Accounting Review. Finalmente, por meio da relação entre os principais artigos da análise bibliométrica com as características da análise sistêmica, conclui-se que um artigo de destaque em comportamento dos custos possui abordagem quantitativa (com a utilização de regressões robustas), reconhece a existência dos Sticky Costs (independente da abordagem utilizada), utiliza diversos fatores explicativos (internos e externos) e acrescenta alguma variável ou informação para a evolução científica do tema.

A educação financeira é uma ferramenta que auxilia os indivíduos em tomadas de decisões mais assertivas e eficientes no contexto monetário de suas vidas, diante dessa importância tem-se como objetivo principal deste trabalho investigar o nível de educação financeira dos habitantes do Rio Grande do Sul e identificar se existem diferenças nos níveis de educação segundo as variáveis socioeconômicas e demográficas. Para isso realizou-se uma pesquisa com 1.067 indivíduos e a análise dos dados foi através da estatística descritiva e multivariada. Os principais resultados revelam maiores níveis de educação financeira entre os homens, solteiros, que não possuem dependentes, estudantes e/ou bolsistas, com um maior nível de escolaridade, tanto seu, quanto dos seus pais, com maiores faixas de renda própria e familiar e residentes na região centro ocidental rio-grandense. Todavia, o nível de educação financeira na amostra de rio-grandenses avaliada atingiu patamares preocupantes, ao acertaram 67% das questões de educação básica e 62,34% das questões de educação avançada, revelando um nível médio de educação financeira, porém muito próximo ao nível baixo (abaixo de 60%). Esses resultados geram uma conscientização sobre a necessidade de novos investimentos por parte do governo ou de instituições privadas em programas de educação financeira, voltados principalmente aos grupos que se mostraram com menor conhecimento

Artifacts by Misalignment of Cardiac Magnetic Resonance Phased-array Coil Elements: From Simulation to In vivo Test
Authors: De Marchi Daniele , Flori Alessandra , Martini Nicola , Giovannetti Giulio
Published: October 2017

Background:

Cardiac magnetic resonance evaluations generally require a radiofrequency coil setup comprising a transmit whole-body coil and a receive coil. In particular, radiofrequency phased-array coils are employed to pick up the signals emitted by the nuclei with high signal-tonoise ratio and a large region of sensitivity.

Methods:

Literature discussed different technical issues on how to minimize interactions between array elements and how to combine data from such elements to yield optimum Signal-to-Noise Ratio images. However, image quality strongly depends upon the correct coil position over the heart and of one array coil portion with respect to the other.

Results:

In particular, simple errors in coil positioning could cause artifacts carrying to an inaccurate interpretation of cardiac magnetic resonance images.

Conclusion:

This paper describes the effect of array elements misalignment, starting from coil simulation to cardiac magnetic resonance acquisitions with a 1.5 T scanner.  Phased-array coil simulation was performed using the magnetostatic approach; moreover, phantom and in vivo experiments with a commercial 8-elements cardiac phased-array receiver coil permitted to estimate signal-to-noise ratio and B1 mapping for aligned and shifted coil.

Published: October 2017

The fundamental objective of the national housing agenda is to ensure a better quality of life. The challenge is to develop affordable houses whilst sustaining positive social neighbourhoods. In the western world, research equated the physical environment as a dominant influence on the spatial behaviours of communities. Quality of living in Malaysia is only obtainable to the upper echelons in the organic planning of housing. These perceived as successful neighbourhoods such as the cul-de-sac or Tessellation Planning create a relationship between the physical environment and the neighbourhood. This paper initiates a search for such literature and identifies key concepts for further deliberations.
HIV Cure Goes Viral: An Analysis of HIV Cure #Hashtags from Twitter Around the Mississippi Baby Announcement (Preprint)
Authors: Gilbertson Adam
Published: October 2017

BACKGROUND

On 3 March 2013, an announcement was made concerning the possible functional HIV cure of the “Mississippi baby” at the Conference on Retroviruses and Opportunistic Infections (CROI) in Atlanta, Georgia, USA. Immediately following this announcement, word spread across traditional media outlets, and social media platforms such as Twitter, rousing tremendous public excitement.

OBJECTIVE

The purpose of this study was to examine the frequency, content, and sentiment of HIV cure-related messages (tweets/retweets) on Twitter around the HIV “cure” Mississippi baby announcement on the 3 of March 2013.

METHODS

We obtained a dataset containing all HIV cure messages between 13 January and 16 May 2013 and conducted qualitative analyses on a 1,111-message sample.

RESULTS

A sharp increase (2,786%) in HIV cure-related messages occurred immediately following the announcement. However, this sharp increase only lasted approximately 19 days. Out of our sample of 1,111 messages most were from individuals (68.1%) or news organizations (18.3%), including the single most retweeted post from the BBC (20,047 retweets). 36.6% of these messages were coded as opinion/commentary and 26.7% were coded as news. The proportion of messages with neutral sentiment increased (42.5% to 53.9%; P = 0.003 while the proportion of those with negative sentiment decreased (15.6% to 9.2%; P = 0.01.

CONCLUSIONS

The Mississippi baby announcement substantially increased HIV cure-related social media messages. Tweets from individuals dominated this platform; messages from public health agencies were relatively under-represented. The increased public attention garnered after the announcement was short-lived. Similar surges in public attention following future HIV cure breakthrough announcements may offer opportunities to reduce negative perceptions of HIV and improve community engagement.

Published: October 2017

Left ventricular assist devices (LVADs) are common and implantation carries risk of AKI. LVADs are used as a bridge to heart transplantation or as destination therapy. Patients with refractory heart failure that develop chronic cardiorenal syndrome and CKD often improve after LVAD placement. Nevertheless, reversibility of CKD is hard to predict. After LVAD placement, significant GFR increases may be followed by a late return to near baseline GFR levels, and in some patients, a decline in GFR. In this review, we discuss changes in GFR after LVAD placement, the incidence of AKI and associated mortality after LVAD placement, the management of AKI requiring RRT, and lastly, we review salient features about cardiorenal syndrome learned from the LVAD experience. In light of the growing number of patients using LVADs as a destination therapy, it is important to understand the effect of these devices on the kidney. Additional research and long-term data are required to better understand the relationship between the LVAD and the kidney.
El uso de Twitter en el análisis financiero: aproximacion desde la econofísica
Authors: García Medina Andrés
Published: October 2017

Se han utilizado  técnicas matemáticas provenientes de la física estadística, especialmente de la teoría de matrices aleatorias (RMT, por sus siglas en inglés), para analizar datos textuales de Twitter en el contexto de los mercados financieros globales. Para esto, se han analizado un periodo de tiempo de 7 meses a lo largo de 2014, considerando los retornos de 20 índices financieros globales para comparar los resultados. La información textual se logró extraer mediante el ensamblaje de distintos lenguajes de programación, construyendo series de tiempo de polaridad mediante  el análisis de sentimiento. RMT reveló que existen correlaciones verdaderas en los índices financieros y las polaridades . Además, se encontró una buena concordancia entre el comportamiento temporal de los eigenvalores extremos de los retornos y polaridades, con resultados similares para la razón de participación inversa, lo cual nos da información acerca de la emergencia de factores comunes en la información financiera global, sin importar si estamos utilizando polaridades o retornos como fuente de datos.  Nuestros resultados sugieren que al utilizar las polaridades de Twitter y NYT como un nuevo indicador financiero, proveen de información relevante acerca del comportamiento colectivo  de los índices financieros globales. Esto genera una fuerte y novedosa evidencia en contra de la hipótesis de mercado eficiente, y apoya la tendencia de la economía conductual, la cual afirma que los precios de los mercados se ven afectados por las decisiones irracionales de los inversionistas, siendo estos influenciados por la tendencia de las noticias y redes sociales.

La sociología económica : orientación teórica, aparato conceptual y aspectos metodológicos de un campo de investigación en ciencias sociales
Authors: Pérez Amaury
Published: October 2017

La sociología económica constituye hoy día uno de los campos más innovadores de la sociología contemporánea. Para caracterizarla, no basta invocar el apadrinamiento de la economía y de la sociología. Tanto la economía social como la socio-economía y el neoinstitucionalismo reivindican a la vez, esta doble herencia. La particularidad de la sociología económica reside principalmente en que se cimentó en los trabajos de los padres fundadores de la sociología de principios de siglo XX, al tiempo de beneficiar de los resultados recientes del análisis estructural que muestran la necesidad de comprender la economía como un hecho social Como bien señala nuestro sub-titulo, mediante este artículo pretendemos introducir al mundo académico dominicano la sociología económica, presentando la orientación teórica, el aparato conceptual y los aspectos metodológicos de este campo de investigación en ciencias sociales.

La exposición al plomo constituye un grave problema de salud pública, ya que afecta a las poblaciones, provocando efectos agresivos al nivel económico más vulnerable: niños, mujeres, trabajadores El objetivo general de este estudio es establecer en términos de distancia la zona de influencia de las fuentes de emisión de plomo en el barrio Villa Francisca de la ciudad de Santo Domingo, utilizando el sistema de información geográfica, con el fin de estimar el tamaño de la población expuesta Este estudio es de tipo descriptivo y transversal, en el mismo se consideraron características ambientales del sector, información demográfica, fuentes de emisión de plomo, niveles de plomo en sangre de niños y niveles de plomo ambiental. Estas variables se relacionaron en el espacio geográfico del sector para determinar el área de influencia de las fuentes de emisión y estimar el tamaño de la población expuesta El 36.5% de los niños presentó niveles sanguíneos de plomo elevados, relacionados directamente con la cercanía de talleres que trabajan con plomo. Según el área de influencia de las fuentes de emisión identificadas se consideró que la población expuesta en este barrio es la población general, estimada en 23,103 habitantes. Por lo que se recomienda una intervención multisectorial estatal con el fin de tomar medidas para el control de las emisiones de plomo y buscar alternativas de sobrevivencia que no afecten negativamente las personas que lo habitan ni al ambiente.
The Rubik’s cube of postcolonialism: Theory's syncretism and challenges in postcolonial studies
Authors: Jovanovic Natasa
Published: October 2017

The paper examines the genesis of postcolonialism in various (mutually
conditioned) forms: at the conceptual, humanistic, theoretical and
disciplinary level. With the contextualization of the work of the first
authors who put the question mark on the established and dominant
western-centric perception of global divisions, we will (de)construct various
historical and paradigmatic influences on the development of postcolonialism.
A special emphasis is put on the position of postcolonialism within the
so-called Great Debates in the academic discipline of International
Relations. Also, we consider the possibility of development of
postcolonialism as a theory on the medium level that has a multiple utility
for International Relations. A critical examination of the initial
assumptions of postcolonialism as inherently processual, reflexive and
subversive, will open up the issues of the contemporary challenges of the
social life of former colonies and their relationships with other actors on
the international scene. One of the major issues (which can be set as a
hypothesis) is how to use the advantage of the epistemological and
theoretical postulates of postcolonialism in the research of the modern world
in which the orientalist rhetoric largely survives, but due to the rise of
terrorism and large-scale migration from the Middle East, the political and
social reality is changed?

Introduction/Objective. Lyme borreliosis is a multisystem infectious disease caused by Borrelia burgdorferi spirochetes transmitted by the bite of an infected tick. The disease manifestations are very different, with the skin, joints, heart, and nervous systems being most often affected. The aim of this study was to find out whether there are significant differences in the appearance of symptoms and signs of the disease between the subjects who did / did not receive prophylactic, early antibiotic therapy, after the tick bite in patients diagnosed with the early phase of Lyme borreliosis. Methods. The study was carried out on 2,070 patients, who were treated or examined at the Clinic for Infectious and Tropical Diseases in the 1989?2004 period. The patients were divided into group ? (n = 591), in which they were given early antibiotic therapy, and group B (n = 1,479), in which they were not. The antibiotic therapy was used within five days of a tick bite in patients with a probable infection, who, at the time, did not have any symptoms or signs. The applied antibiotics included cephalosporins, macrolides, tetracyclines, semisynthetic penicillins, repeatedly for seven or 14 days, or benzathine benzylpenicillin once only. Results. The disease developed in a statistically significantly larger number of patients who were not given early antibiotic therapy (537/1,479) than in those who received the therapy (10/951), i.e. the ratio was 36.3% vs. 1.7%. We concluded that only two antibiotics were sufficient for optimal prevention: doxycycline and ampicillin, administered for seven days. The applied antibiotics showed a high statistically significant efficacy, ranging from 93.7% (cephalosporins) to 99.4% (macrolides). Conclusion. The application of early antibiotic therapy after a tick bite was effective in preventing the early phase of Lyme borreliosis, while in the case of infection it prevented the development of extracutaneous manifestations.
Versiones del montaje masoquista
Authors: Testa Adriana
Published: October 2017

El artículo está centrado en una hipótesis de Jacques Lacan [1970] que postula como una de las claves del escenario contemporáneo “la manía sadomasoquista que caracteriza a nuestro […] ambiente sexual”. Las prácticas actuales tales como las del tatuaje, el piercing, el cutting, las dietas, los ayunos anoréxicos, las de autofl agelación monacales, incluyendo también las prácticas SM generalizadas como lo es por ejemplo el bondage y otras, ponen en evidencia esa manía y en particular la economía del masoquismo. Por esta razón, más allá de sus formas extendidas, atañen a efectos de estructura, que no se limitan a los imperativos de la época sino que exteriorizan el estatuto del cuerpo como el lugar del Otro donde se inscriben las marcas de goce.

En la actualidad se ha producido un cambio en relación a los ideales, donde los padres no sirven más de modelo al cual identifi carse, sino que otras fi guras, incluso pares, entre los cuales se vuelven más fuertes las identifi caciones horizontales, ocupan su lugar. El Otro familiar no ofrece ninguna garantía y la fama, la belleza, el éxito, incluso, el desencanto, se erigen como ideales a seguir, generando entre los seguidores efectos no siempre benéficos. Se estudiará un grupo de rock y los distintos fenómenos que han generado en torno a ellos. Sus fans son jovencitas recién salidas de la pubertad. El marco del psicoanálisis nos servirá de referencia para poder pensar estas cuestiones sin caer en un relativismo ético o en una psicologización banal.

Diversos estudios han mostrado que las habilidades relacionadas con el reconocimiento de la palabra escrita predicen la comprensión lectora durante los primeros años escolares, pero no así en los años superiores planteando incluso que llegarían a ser habilidades independientes. En este trabajo nos propusimos analizar, a partir de una muestra de 2,403 estudiantes de primer año de universidad, la relación entre el reconocimiento de la palabra escrita, considerando los aspectos de precisión y velocidad, y la lectura de textos escritos elaborados por docentes de Literatura en el bachillerato. Los resultados dan muestra de una relación significativa leve entre el reconocimiento de la palabra escrita y la respuesta efectiva a preguntas de comprensión de textos escritos, en estudiantes con dificultades en el acceso lector. Se discuten estos resultados en el marco de los modelos cognitivos de la lectura que destacan el conocimiento léxico-semántico en el acceso léxico.

Authors: Gómez Carrasco Cosme J. , Sáiz Jorge
Published: October 2017

This paper addresses narrative thinking and literacy levels in future primary school teachers in Spain. It uses the study of a historical synthesis of one of the main narratives in Spanish history: the Christian expansion through Muslim territories in the Iberian Peninsula in the Middle Ages. Accounts by 283 students of the degree in elementary school teaching at the universities of Valencia and Murcia were studied. The aim was to ascertain the students' discursive abilities with respect to their historical thinking skills. The results reveal poor narrative skills in future teachers and a very low level of historical literacy.

Performance of soybean growth and development is influenced by environmental conditions. On similar soil fertility conditions but different environmental conditions such as rainfall will also lead the changes in the performance of the plant. The research aimed to study the agronomic performance of the potential soybean lines in two different drought acid land agroecologies. The experiment was conducted at the South Lampung Tegineneng experimental station and East Lampung Taman Bogo experimental station from February until May 2013. The South Lampung Tegineneng experimental station has a pH of 5.50 and an average rainfall of 89 mm per month, and The East Lampung Taman Bogo experimental station has a pH of 5.12 and an average rainfall of 213 mm per month. The experiment consisted of 10 soybean lines adapted acid land and two check varieties. The experiment was arranged in randomized completely block design with four replications. The least significant different test (LSD) at α = 0.05 was used to calculate significant differences among all treatments. The results showed that rainfall influenced agronomic performance of soybean more than soil acidity. The yield performance in South Lampung was lower than in the East Lampung. Four genotypes produced higher grain yield than the Tanggamus variety in both locations, i.e. Tgm/Anj-862, Tgm/Anj-784, Tgm/Anj-888 Tgm/Anj-857, and Tgm/Anj-858. Tgm/Anj-862 was the most superior genotypes for having the highest number of branches, number of pods, and 100-seeds weight and seed yield and consistent at both locations. The four genotypes, especially Tgm/Anj-862, were potential to be developed in both locations or other locations with similar environmental conditions.Keywords: grain yield, ultisol, yield components

Published: October 2017

The use of somatic embryo for in vitro selection program is very useful since the selected traits will be inherited in the progeny. This study was aimed to obtain somaclonal variants for drought tolerances of soybean genotypes from in vitro selection using polyethylene glycol (PEG). The experiments were set up in two factors with completely randomize design and each treatment was replicated ten times. Four soybean genotypes (Tanggamus, Anjasmoro, Yellow Biloxi, CG-22-10, and SP-10-4) were used in this study as first factor experiment. In vitro selection was in embryogenic callus level using media containing PEG (0, 5, 10, 15, and 20%) as second factor experiment was done to all genotypes. The results showed that after 3 months in the selection medium, SP-10-4 and Tanggamus genotypes showed higher percentage of fresh callus (surviving callus) and number of embryogenic callus, compared to Anjasmoro and Yellow biloxi. In contrast, CG-22-10 had the lowest number of fresh callus and number of embryogenic callus compared to other genotypes. PEG in high concentration decreased the percentage of fresh callus and number of embryogenic callus in all genotypes. Tanggamus was the only genotype that survived until cotyledonary-stage embryos after transferring in MS0 regeneration medium. Seven Tanggamus somatic embryos from PEG selection succesfully germinated and regenerated into plantlet as drought-tolerant somaclone candidates.  Keywords: abiotic stress, embryogenic callus, Glycine max, somaclone

Nutmeg is an Indonesian native plant, produces essential oill as an export commodity. However, it has low seed uniformity that mengurangi keseragaman tanaman di lapang. The main objective of this research was to obtain morphological characteritics as parameter for nutmeg mother plants selection. This field research was carried out from August-December 2014 at Toisapu, Wakal and Lula nutmeg seed source plantations in Ambon, and Seed Storage and Testing Laboratory, IPB. Characterization was undertaken on ten mother plants from each  Wakal and Lula seed source plantations and eight mother plants from Toisapu seed source plantation. Quantitative and qualitative characters of vegetative, fruit, mace and seed from every mother plants were analyzed with  Gower’s similarity test. Mother plants that produced high uniformity seed was the 7th (0.80), the 8th (0.93) and the 10th (0.80) mother plants in Wakal; the 2nd (0.80) mother plant in Toisapu; the  2nd (0.82), the 5th (0.80), the 6th (0.82), the 8th (0.84), the 9th (0.80) and the 10th (0.93)  mother plants in Lula. Those selected mother plants produced morphological uniform seed morphologically. Lula seed plantation had the highest uniformity level among mother plants (0.77-0.87) compared to Toisapu (0.70-0.87) and Wakal (0.69-0.84) mother plants. The morphological characteristic can be use to select the source seed mother plants which able to produce high morphological uniformity seeds.Keywords: Gower’s similarity, seed production, uniformity

Nitrogen-fixing Azotobacter is widely used as biofertilizer in sustainable agriculture. The bacteria produce exopolysaccharide which might have a significant role in enhancing soybean nitrogen uptake and growth. The objective of this research was to obtain growth media of Exopolysaccharide–producing Azotobacter; and increase shoot and root growth as well as nitrogen uptake of soybean var. Anjasmoro at early vegetative phase following inoculation of Azotobacter chroococcum liquid. Research consist of two phase, 1) determination of organic-based media for A. chroococcum liquid inoculant production, and 2) pot experiment for application of liquid inoculant on soybean.  The first experiment was performed  in a series of  batch fermenter consisted of several organic media for 72 hours.  The second experiment was set in completely randomized design consisted of three density of liquid inoculant. The results verified that the best media which induced exopolysachharide production of A. chroococcum was 1% molase enriched with 0.1% NH4Cl. Liquid inoculant clearly enhanced population of Azotobacter in soybean rhizosphere, plant height, roots dry weight and N uptake of 21 day old soybean. This research implied that A. chroococcum might be used as biofertilizer at early growth of soybean. Keywords: Azotobacter chroococcum, biofertilizer, liquid inoculat
Oral Immunotherapy in Children with IgE-mediated Hen's Egg Allergy: Follow-ups at 2.5 and 7 Years
Authors: Meglio Paolo , Giampietro Paolo Gianni , Carello Rossella , Galli Elena
Published: October 2017

Background

The present report was a follow-up investigation at 2.5- and 7-year intervals of a previous study of 20 children with moderate-to-severe immunoglobulin E (IgE) mediated hen's egg (HE) allergy who received oral immunotherapy (OIT) with raw HE. The study design of the previous study divided the 20 subjects into two groups of 10 each: (1) group 1, the OIT group (OIT-G), and, (2) group 2, an age-matched control group (C-G). In that study, 8 of 10 of the children in the OIT-G were successfully desensitized, one child was partially desensitized, and desensitization failed in one child. The aims of the present study were to evaluate the long-term effectiveness and safety profile of OIT with raw HE, and to assess the course and prognostic value of skin-prick tests (SPT) and serum-specific HE-IgEs in this study population.

Methods

Of the 20 children who were recalled, 2 dropped out, which left 18 to be evaluated. Information on their HE intake was recorded, and SPTs with HE allergen extracts and with raw and hard-boiled HE were performed. Ovomucoid- and ovalbumin-specific IgE levels were also measured.

Results

At the first (2.5-year) and second (7-year) follow-ups, 87.5% of the children in the OIT-G who tolerated raw HE were still tolerant, whereas the children in the C-G were significantly less tolerant. Overall, cutaneous sensitivity to HE significantly decreased after the 6-month desensitization period and at both follow-ups with regard to the OIT-G but not with regard to the C-G. A significant reduction in serum ovomucoid- and ovalbumin-specific IgE levels was seen in both the OIT-G and the C-G.

Conclusion

Clinical raw HE tolerance induced by OTT persists over time. Negativization of SPTs could be considered a more reliable prognostic indicator of clinical tolerance to raw HE than the reduction in specific-HE IgE levels. Raw-HE OIT would seem to be a promising method to treat HE allergy.

Background

There is an ongoing discussion concerning the potential origins of chronic rhinosinusitis with nasal polyposis (CRSwNP).

Objective

The aim of this study was to quantify subpopulations of T cells in peripheral blood and nasal polyps in CRSwNP to examine their influence on the etiology of this disease.

Methods

Tissue and blood samples were collected from 11 patients who underwent nasal sinus surgery, and these samples were analyzed by multicolor flow cytometry.

Results

There was a significantly lower frequency of CD4+ T-helper (Th) cells and a significantly higher frequency of CD8+ T cells among lymphocytes isolated from nasal polyps compared with peripheral blood mononuclear cells (PBMC). In both T-cell subpopulations, a shift mainly from naive T cells among peripheral blood lymphocytes toward an effector memory and terminally differentiated subtype predominance in nasal polyps was observed. Among CD4+ T cells, the frequencies of cluster of differentiation (CD) 45RA- Forkhead-Box-Protein P3high (FoxP3high) cytotoxic T-lymphocyte-associated Protein 4high (CTLA-4high) activated regulatory T (Treg) cells, and CD45RA- Forkhead-Box-Protein P3low (FoxP3low) memory T cells were significantly increased in nasal polyps compared with PBMC.

Conclusion

In this study, we presented a detailed characterization of CD4+ and CD8+ T-cell subpopulations in patients with CRSwNP. CD8+ T cells were more prominent in nasal polyps than in CD4+ T cells. Both nasal CD8+ T cells and CD4+ T cells predominantly had an effector memory phenotype. Among CD4+ T cells, activated Treg cells were increased in nasal polyps compared with PBMC. The data point toward a local regulation of T-cell composition within the microenvironment of nasal polyps, which might be further exploited in the future to develop novel immunotherapeutic strategies.
Barosinusitis: Comprehensive Review and Proposed New Classification System

Published: October 2017

Background

Barosinusitis, or sinus barotrauma, may arise from changes in ambient pressure that are not compensated by force equalization mechanisms within the paranasal sinuses. Barosinusitis is most commonly seen with barometric changes during flight or diving. Understanding and better classifying the pathophysiology, clinical presentation, and management of barosinusitis are essential to improve patient care.

Objectives

To perform a comprehensive review of the available literature regarding sinus barotrauma.

Methods

A comprehensive literature search that used the terms “barosinusitis,” “sinus barotrauma,” and “aerosinusitis” was conducted, and all identified titles were reviewed for relevance to the upper airway and paranasal sinuses. All case reports, series, and review articles that were identified from this search were included. Selected cases of sinus barotrauma from our institution were included to illustrate classic signs and symptoms.

Results

Fifty-one articles were identified as specifically relevant to, or referencing, barosinusitis and were incorporated into this review. The majority of articles focused on barosinusitis in the context of a single specific etiology rather than independent of etiology. From analysis of all the publications combined with clinical experience, we proposed that barosinusitis seemed to fall within three distinct subtypes: (1) acute, isolated barosinusitis; (2) recurrent acute barosinusitis; and (3) chronic barosinusitis. We introduced this terminology and suggested independent treatment recommendations for each subtype.

Conclusion

Barosinusitis is a common but potentially overlooked condition that is primed by shifts in the ambient pressure within the paranasal sinuses. The pathophysiology of barosinusitis has disparate causes, which likely contribute to its misdiagnosis and under diagnosis. Available literature compelled our proposed modifications to existing classification schemes, which may allow for improved awareness and management strategies for barosinusitis.

One of the unique local wisdoms implemented by the local community in Nagari Sikucur,Padang Pariaman West Sumatera is “banned fish”. However, changes and shifts in people's lifestyles affect the pattern and values adopted by the local community, including the local wisdom of the community in that area. In order to describe the local wisdom in that area, a qualitative study was conducted. This study was aimed to answer some research questions figuring social phenomena related to local wisdom in West Sumatera people. The results showed that management of banned fish in Nagari Sikucur has been implemented as informal public policy in order to preserve fish population in their rivers. Such agreement has successfully conserved the ecosystem while another impact also attracted people in seeing such ecotourist system. Management of such local wisdom is applied in well practice, accepted and bind to the whole society member. People are benefited with such local wisdom by having clean water in the river that can be used for their agricultural activities.
