Os Valores e os Instrumentos de Gestão Social: Um Estudo de Casos Múltiplos com Conselhos de Direitos da Criança e do Adolescente
Authors: Almeida Elizabeth Aparecida da Costa , Cabral Eloisa Helena de Souza
Published: July 2015

Com a abertura política e o advento da Constituição Federal de 1988, a participação da sociedade civil em políticas públicas ganha importância e, assim, mecanismos e canais de participação são criados. Entre eles, os Conselhos de Direitos da Criança e do Adolescente (CMDCAs). Este artigo identifica os valores da política nacional, valores do espaço público e instrumentos de gestão social que orientam presidentes e conselheiros na tomada de decisão. A pesquisa valeu-se de um estudo de casos múltiplos com CMDCAs, apoiados pela Cemig. A metodologia compreendeu estudos iniciais, etapa exploratória, com aplicação de questionários, revisão da bibliografia e análise documental do Regimento Interno e Resoluções dos Conselhos. A teoria de valores de Schwartz foi empregada como referência na construção do questionário. Os resultados apontaram que os instrumentos de gestão social ainda são práticas a serem implementadas, que os valores do espaço público e da política nacional estão presentes no processo decisório, as percepções de importância diferem, ou seja, não são percebidos na mesma ordem de importância, sinalizando relação de conflito entre presidentes e conselheiros. Palavras-chave: conselhos; valores; gestão social; políticas públicas; território.AbstractWith the political openness and the advent of the 1988 Federal Constitution, the participation of civil society in public polities grows in importance and therefore participation means and mechanisms are built up. Among them, we find the Councils for the Rights of Children and Adolescents (CMDCA). This paper identifies the values of national policies, values of the public space and instruments of social management that guide the decision-making process of chairmen and councilors. The research relied on a multiple case study on CMDCA, supported by CEMIG. The methodology included preliminary considerations, the exploratory stage with questionnaires administration, bibliographic review and document analysis of the By-laws and the Council Resolutions. Schwartz's value inventory was used as reference in the construction of the questionnaire. Findings reported that the instruments of social management are still practices that need to be implemented, that the values of the public space and national policies are part of the decision-making process, that the perceptions of the relevance differ, that is, are not perceived in the same order of importance, indicating a relationship of conflict between chairmen and councilors.

Estudo de Políticas Públicas a Partir de Narrativas: O Caso do Processo de Elaboração do Programa de Revitalização e Desenvolvimento da Região Central Histórica de Santos
Authors: Bittencourt Lúcio Nagib , Fontenelle Isleide Arruda
Published: July 2015

Reconhecendo a existência de diferentes perspectivas sobre como conduzir estudos sobre políticas públicas, este artigo traz como proposta abordagem teórico-metodológica cujas bases são: a noção de Alvesson e Kärreman de pesquisa social como construção de enredos de suspense tendo o objeto empírico como disparador; o conceito de Spink de campo-tema; e, principalmente, o levantamento e estudo das narrativas conforme indicado por Czarniawska. O caso escolhido para explorar essa abordagem é o processo de elaboração do Programa de Revitalização e Desenvolvimento da Região Central Histórica de Santos, também conhecido como programa Alegra Centro. Sugere-se que o instrumento de estudo de narrativas demonstra-se capaz de reconhecer a complexidade do campo-tema e, nesse sentido, das políticas públicas que são objeto de nossos estudos, lançando luz e mapeando questões de pesquisa em diálogo com os atores que com elas se relacionam no cotidiano.Palavras-chave: Políticas públicas, narrativas, público, centros históricos, revitalizaçãoAbstractAcknowledging the existence of different perspectives about how to study public policies, this paper proposes a theoretical-methodological approach based on: Alvesson and Kärreman ́s notion on social science inquiry as constructing mysteries based on empirical matters; Spink ́s concept of "theme-field"; and, most of all, the gathering and studying of narratives, according to Czarniawska ́s work. The case study chosen to explore this approach is the elaboration process of the Program for Revitalization and Development of the city of Santos ́ Central Historical Region, also known as Cheer Up Centre. We suggest that the narrative studies shows itself capable of acknowledging the complexity of the theme-field and, in that sense, of the public policies that are object of our studies, enlightening and mapping research questions in dialogue with actors that are related to them in everyday life.Keywords: Public policy, narratives, public, historic centres, revitalization

Regime de Bem-estar Social no Brasil: Três Períodos Históricos, Três Diferenças em Relação ao Modelo Europeu Social-democrata
Authors: Grin Eduardo José
Published: July 2015

Resumo O regime de bem-estar social no Brasil pode ser comparado com o modelo social-democrata europeu em três períodos históricos, apesar das especificidades e diferenças que aqui adquiriu. No período 1930-1964, serão abordadas a importância da concepção de cidadania regulada para a definição de direitos sociais no Brasil e a comparação com o desenvolvimento da cidadania nacional e o papel dos sindicatos no welfare state na Europa. No período 1964-1985, será apresentada a forma como se estruturou a política social do regime militar, enquanto, na Europa, havia um ambiente democrático, com direitos sociais universais e participação social como bases do regime de bem-estar social. No período após 1985, com ênfase na fase da segunda reforma social iniciada pós-Plano Real (1994), será destacada a visão mais generosa e universalizante de direitos sociais. Para esse período, será importante apontar como, na Europa, nesse momento, se questionaram as bases materiais e a concepção do welfare state, visando, ao mesmo tempo, revisar alguns fundamentos para mantê-lo como padrão de solidariedade social.Palavras-chave: cidadania; direitos; igualdade; democracia; desigualdade. AbstractThe social welfare system in Brazil can be compared with the European social democratic model in three historical periods, despite the specificities and differences. The period of 1930-1964 will address the importance of the concept of citizenship regulated to the definition of social rights in Brazil and compare it with the development of national citizenship and the role of trade unions in the welfare state in Europe. The period of 1964-1985 will present the structure of the military regime's social policy while in Europe there was a democratic environment with universal social rights and social participation as the basis for the system of social welfare. The period after 1985, with emphasis on the second phase of social reform initiated after the Real Plan (1994), will highlight the more generous and universalizing vision of social rights. This period will be important to compare as Europe, at that time, questioned the material foundation and the design of the welfare state while aiming to review some grounds to keep it as a pattern of social solidarity.Key words: Citizenship - Rights - Equality - Democracy - Inequality

Published: July 2015

RESUMOO artigo analisa criticamente os formulários de Acompanhamento Familiar dos Beneficiários do Programa Bolsa Família (PBF) em situação de descumprimento das condicionalidades na Educação. Os acompanhamentos foram realizados no período de doze meses (2011-2012) pela equipe técnica do Centro de Referência de Assistência Social (CRAS), do município de Riachão do Jacuípe no estado da Bahia. Trata-se de uma pesquisa de análise documental, com abordagem qualitativa, que explora alguns pontos de discussão em torno dos motivos da baixa frequência escolar de crianças e jovens beneficiários do PBF e do papel do CRAS no fortalecimento do vínculo familiar com a escola e a comunidade. O estudo sugere que há dissonâncias no registro dos motivos da baixa frequência escolar no Sistema Presença do MEC, o que compromete a acessibilidade, a permanência e qualidade do ensino, a intersetorialidade e o repasse financeiro às famílias. Ao final, discutem-se os principais desafios da sustentabilidade futura do PBF por meio da articulação em rede, ressaltando a importância do Acompanhamento Familiar como uma das ações que potencializa o acesso aos serviços públicos e consolida a cidadania. PALAVRAS-CHAVE: Programa Bolsa Família. Acompanhamento familiar. Escola. Intersetorialidede. Condicionalidades. Abstract This paper critically analyzes the Bolsa Família Program's (PBF) Beneficiaries Monitoring Family in a situation of non-compliance with conditions in Education.

Os Desafios da Política Social na América Latina
Authors: De La Cuadra Fernando Marcelo
Published: July 2015

ResumoEste artigo pretende dar uma resposta ao aparente paradoxo existente entre os significativos recursos destinados a programas sociais nos países de América Latina e os relativamente escassos resultados do esforço para a solução dos problemas de pobreza e desigualdade na região. Como chave explicativa desse paradoxo, nossa tese consiste em que, além dos problemas de gestão e de eficácia na aplicação dos recursos, se constata a ausência da dimensão política na aplicação da política social, deficit que se deve em grande parte ao receio expresso pelas autoridades às variadas formas de participação cidadã, apreensão que tende a privilegiar a manutenção da governabilidade e a ordem social em detrimento do envolvimento e da atuação direta dos cidadãos nos assuntos que são de sua competência.Palavras-chave: América Latina; Política Social; Governabilidade, Democracia, Participação cidadã.
A Coordenação Federativa de Políticas Públicas: uma análise das políticas brasileiras nas últimas décadas
Authors: Lotta Gabriela Spanghero , Gonçalves Renata , Bitelman Marina Farkas
Published: July 2015

ResumoEste artigo apresenta o panorama do processo de coordenação de políticas por parte do governo federal no período da pré-Constituição Federal/88 e entre 1988-2012, contribuindo para explicitar, de modo empírico, a dupla tendência presente no contexto federativo brasileiro: transferência de recursos e descentralização de competências e de coordenação federal das políticas. Parte-se da revisão da literatura em que se fundamenta esse debate, acerca dos impactos e resultados do processo de descentralização de políticas sociais no modelo federativo brasileiro desde a promulgação da Constituição Federal (CF) de 1988. Em seguida, sistematiza-se a evolução de nove políticas públicas com ênfase em quatro marcos temporais: antes de 1988, as mudanças introduzidas pela CF de 1988, os movimentos ocorridos ao longo da década de 1990 e os anos 2000. Por fim, apresenta-se uma síntese do panorama atual das políticas a partir de categorias de análise que permitem identificar, no contexto federativo brasileiro, uma tendência geral de coordenação por parte do governo federal.Palavras-chave: Federalismo, políticas públicas, coordenação federativa, descentralização, relações federativas
Articulações intergovernamentais: alcances e limites da coordenação e cooperação na gestão municipal em Moçambique
Authors: Simione Albino Alves
Published: July 2015

ResumoEste artigo apresenta os resultados da análise das articulações intergovernamentais orientadas para promover coordenação e cooperação no processo de implementação de políticas públicas em Moçambique. Analisa de maneira exploratória-interpretativa, com base em um estudo de caso sobre o Município de Xai-Xai, como os incentivos às articulações intergovernamentais estabelecidos pelo Decreto n. 11/2005, de 25 de Abril, têm sido utilizados. O objetivo é gerar subsídios para o melhor entendimento de questões ligadas às condições estruturais, institucionais e administrativas em que as articulações ocorrem. A revisão da literatura foi feita à base de um quadro teórico que explora a abordagem da governança no setor público, situando-a na gestão intergovernamental e na administração pública. Os resultados demonstram que, apesar de existir grande interesse na aplicação de algumas práticas de articulação, ainda existem falhas na operacionalização dos mecanismos adotados, dado que as relações intergovernamentais são ainda fortemente condicionadas por problemas de natureza estrutural e organizacional e caracterizadas por grandes descontinuidades.Palavras-chave: Articulações intergovernamentais, Gestão pública, Governança, Políticas públicas, Colaboração
Usos e significados do dinheiro: uma análise das estratégias dos mediadores para atualização de circuitos econômicos
Authors: Pauli Jandir , Pies Marcelino
Published: July 2015

RESUMO: Este estudo tem por objetivo levar à compreensão do leitor as estratégias adotadas pelos mediadores para oferecer suporte simbólico às transações monetárias, operadas a partir do acesso de agricultores familiares ao crédito. Para entender essa questão, foi realizado um estudo qualitativo com entrevistas e análise de discursos com base em um Sistema de Crédito Cooperativo, denominado Cresol SC/RS. O aporte teórico que orientou a análise das informações articulou os conceitos de “marcos interpretativos”, de McAdam, McCarthy e Zald (1999), com a noção de “circuitos econômicos” de Zelizer (2005). A conclusão é a de que os mediadores atuam permanentemente na construção de significados para utilização do dinheiro. Suas estratégias propõem um alinhamento entre as dimensões da racionalidade instrumental e o sistema de valores, articulando as expectativas individuais dos agricultores com as estratégias organizacionais do circuito econômico.Palavras-chave: Marcos interpretativos, Circuitos econômicos, Políticas públicas, Cultura, Cooperativas de crédito.
Evidence against pain specificity in the dorsal posterior insula
Authors: Davis Karen D. , Bushnell M. Catherine , Iannetti Gian Domenico , St. Lawrence Keith , Coghill Robert
Published: July 2015

The search for a “pain centre” in the brain has long eluded neuroscientists.  Although many regions of the brain have been shown to respond to painful stimuli, all of these regions also respond to other types of salient stimuli. In a recent paper, Segerdahl et al. (Nature Neuroscience, 2015)  claims that the dorsal posterior insula (dpIns) is a pain-specific region based on the observation that the magnitude of regional cerebral blood flow (rCBF) fluctuations in the dpIns correlated with the magnitude of evoked pain.  However, such a conclusion is, simply, not justified by the experimental evidence provided.  Here we discuss three major factors that seriously question this claim.
Top Educational Paradigm: Use of Indigenous Knowledge of Rural Architecture Sample: Guilan’s Plain Rural Heritage
Authors: Astaneh Seyed , Parvizi Reza , Mahboobi Mohammad , Khah Mojtaba
Published: July 2015

Undoubtedly, an important part of factors leading to an undesirable situation in contemporary Iranian architecture results from inadequate training of architecture. Which model should be adopted in architectural education? A model adopted from reductionist-based formal knowledge or a model that utilizes both formal knowledge and various economic, social, cultural, climatic aspects. The first option does not seem reasonable due to ample frustrations. So, top paradigm is an option able to change the theory and practice in architectural education by exploiting indigenous knowledge as well as formal training. The methodology of this study is analytic that seeks to explain and provide a top model in teaching architecture. The results suggest that indigenous knowledge of rural architecture is one of the basic requirements for achieving an effective approach to desirable development.

Plant specimens of Linum austriacum (Linaceae) were collected from 16 geographical populations of nine provinces in Iran andused for morphological and molecular (ISSR) analyses. Different multivariate and Bayesian methods were used to studyinterpopulations differences. Analysis of variance test and Principal coordinate analysis plots indicated morphological difference of thepopulations. Mantel test revealed positive significant correlation between morphological and geographical distance of these populations.Pearson, coefficient of correlation showed significant correlations between basal leaf length, width and length/width ratio with latitudeand altitude of the studied populations. Bayesian analysis of combined molecular and morphological features revealed divergence of thestudied populations and consensus tree showed separation of 6 populations in different clusters. Canonical Variate Analysis plot of thesepopulations showed that Sang Sefid and Salmas populations differed greatly from the other populations. New ecotypes are suggested forthese populations.
Oedipus in Africa: Mudimbe and classical antiquity
Authors: Orrells Daniel
Published: July 2015

The history of modern European thought has characterized the pursuit of philosophy as an essentially Greek occupation. The Greco-Roman philosophical tradition has also provided models and alibis for the European colonial project. What, then, does it mean to be an African philosopher in this historical context? Can the African philosopher utilize the Greco-Roman tradition for the sake of postcolonialist critique? Or does the African philosopher end up replicating the sins of the father like Oedipus, King of Thebes? This article examines V. Y. Mudimbe’s interest in the meaning of this myth for the postcolonial African philosopher.

L’histoire de la pensée moderne européenne a fait de la philosophie une occupation essentiellement grecque. La tradition philosophique gréco-romaine a aussi fourni des modèles et des alibis au projet colonial européen. Dans un tel contexte historique, que signifie, alors, être philosophe africain? Est-il en mesure de se prévaloir de la tradition gréco-romaine pour monter une critique postcoloniale? Ou doit-il plutôt se résigner, à l’instar d’OEdipe, roi de Thèbes, à répéter les péchés de son père ? Cet article entreprend d’examiner la signification du mythe oedipien dans l’oeuvre de V. Y. Mudimbe et de définir le rôle que le penseur congolais lui assigne dans le cadre d’une philosophie africaine postcoloniale.
Introducción. Una práctica de reflexión sociológica más allá de los marcos nacionales
Authors: Penalva Verdú Clemente , Raffini Luca
Published: July 2015

La crisis que comienza en 2008, y que todavía sigue produciendo sus efectos en Europa, y de manera particular en Italia y España, ha proporcionado el contexto ideal para llevar a cabo una comparación entre las dinámicas de cambio que se han desarrollado en los dos países. Dentro del contexto europeo, España e Italia comparten muchos rasgos comunes y los efectos de la crisis económica en las dimensiones cultural, social y política. La crisis en Italia y en España, al igual que en Grecia y Portugal, ha sido particularmente aguda. Ha golpeado de manera fuerte el sistema económico, generando una caída de la producción y un aumento del desempleo y de la precarización. Se ha reflejado en una serie de recortes que han golpeado a un Estado de Bienestar ya históricamente débil. Ha amplificado las incertidumbres y los riesgos típicos de la tardo-modernidad, así como los procesos de individualización. La crisis económica es a la vez una crisis política, social y cultural, cuyas raíces, así como sus remedios, son consustanciales al modelo neoliberal. La idea de poner en marcha un proyecto comparativo se ha desarrollado a partir de la intuición de que, a pesar de la presencia manifiesta de muchos elementos comunes en los dos países, la crisis, en algunos aspectos, produce dinámicas diferenciadas, sobre todo en la dimensión política. El método comparativo, desde nuestro punto de vista, favorece un planteamiento reflexivo. La comprensión de las dinámicas que se han desarrollado en un país invita a reflexionar críticamente sobre los factores que en el otro país han llevado a dinámicas diferentes, forzando al científico social a no conformarse con las claves explicativas consolidadas, a desarrollar explicaciones multidimensionales, a establecer conexiones y a intentar averiguar de qué manera las dinámicas de cambio global, favorecidas por los procesos de globalización y de europeización, interactúan con variables de contexto y factores específicos. Lo que la comparación nos dice es que, a pesar de los elementos comunes, entre los dos países hay diferencias, tanto en términos de intensidad y de etapas de la crisis, como en términos de respuesta social y política a la crisis.
Contentious precarious generation in anti-austerity movements in Spain and Italy
Authors: Andretta Massimiliano , Della Porta Donatella
Published: July 2015

This article focuses on the precarious generation protesting in Spain and Italy in times of crisis and austerity (2010-2012). Their many similarities notwithstanding, the two countries have experienced different types of mobilization against austerity measures. In Spain, a relatively autonomous mobilization –characterized by new collective actors and new forms of action– has made possible the building of a political actor, Podemos, able to seriously challenge the established political parties. In Italy, instead, the mobilization was dominated by established political actors, especially trade unions, did not produce innovative forms of action and has not been able to overcome (so far) the fragmentation of the social movement sector. In both countries, however, the anti-austerity protests have been characterized by a strong presence of what we call hear the “precarious generation”, particularly exposed to the economic crisis and the austerity measures. By relying on data from several surveys conducted in demonstrations on social, economic and labor issues in the two countries from 2010 to 2011, in this article we single out differences and the similarities in terms of presence, social composition, grievances and emotion, collective identity and network embeddedness of the precarious generation. Our findings show that the precarious generation was almost equally present in the selected demonstrations in the two countries, share similar socio-graphic features and similar types of grievance and emotions. Nonetheless, in Spain it seems to have built a more cohesive and radical collective identity based upon a more informal and internet based network integration while in Italy it seems embedded in a more traditional and formal network, which prevented the formation of a strong collective identity. Moreover, while in Spain the differences between the older and the precarious generation reveal that, both have a strong identity based on different networks; more formal the older and more related to informal and online instruments the latter; in Italy, the older generation has a much stronger collective identity based on a organizational network, while the precarious one is less but still integrated in organizational network. We conclude that the more autonomous civil society tradition in Spain, together with the particular political opportunities, under the pressure of a harsher economic crisis, may account for the differences we found.
Meta periodismo y transparencia informativa en el periodismo del siglo XXI
Authors: Campos-Domínguez Eva , Redondo-García Marta
Published: July 2015

Esta investigación se enmarca dentro del periodismo postindustrial y pretende explorar la información que, sobre sí mismos, incluyen los medios de comunicación del modelo pluralista polarizado (Hallin y Mancini, 2004). Se analiza el grado de transparencia de las webs de seis medios: Italia (RAI-1 y Republica.it), Portugal (RTP-1 y Público.pt) y España (TVE-1 y Elpais.es). El estudio comparado atiende a una categorización desarrollada en base a Bardoel y d’Haenens, 2004; MediaACT, 2010, y Groenhart y Bardoel, 2012. Las conclusiones revelan que la transparencia comienza a difundirse en los sites aún de forma incipiente, de manera que la opacidad se mantiene como característica dominante frente a la rendición de cuentas.
SCAN++
Authors: Shiokawa Hiroaki , Fujiwara Yasuhiro , Onizuka Makoto
Published: July 2015

Graph clustering is one of the key techniques for understanding the structures present in graphs. Besides cluster detection, identifying hubs and outliers is also a key task, since they have important roles to play in graph data mining. The structural clustering algorithm
SCAN
, proposed by Xu
et al.
, is successfully used in many application because it not only detects densely connected nodes as clusters but also identifies sparsely connected nodes as hubs or outliers. However, it is difficult to apply SCAN to large-scale graphs due to its high time complexity. This is because it evaluates the density for all adjacent nodes included in the given graphs. In this paper, we propose a novel graph clustering algorithm named
SCAN
++. In order to reduce time complexity, we introduce new data structure of
directly two-hop-away reachable node set (DTAR).
DTAR is the set of two-hop-away nodes from a given node that are likely to be in the same cluster as the given node. SCAN++ employs two approaches for efficient clustering by using DTARs without sacrificing clustering quality. First, it reduces the number of the density evaluations by computing the density only for the adjacent nodes such as indicated by DTARs. Second, by sharing a part of the density evaluations for DTARs, it offers efficient density evaluations of adjacent nodes. As a result, SCAN++ detects exactly the same clusters, hubs, and outliers from large-scale graphs as SCAN with much shorter computation time. Extensive experiments on both real-world and synthetic graphs demonstrate the performance superiority of SCAN++ over existing approaches.
Taming subgraph isomorphism for RDF query processing
Authors: Kim Jinha , Shin Hyungyu , Han Wook-Shin , Hong Sungpack , Chafi Hassan
Published: July 2015

RDF data are used to model knowledge in various areas such as life sciences, Semantic Web, bioinformatics, and social graphs. The size of real RDF data reaches billions of triples. This calls for a framework for efficiently processing RDF data. The core function of processing RDF data is subgraph pattern matching. There have been two completely different directions for supporting efficient subgraph pattern matching. One direction is to develop specialized RDF query processing engines exploiting the properties of RDF data for the last decade, while the other direction is to develop efficient subgraph isomorphism algorithms for general, labeled graphs for over 30 years. Although both directions have a similar goal (i.e., finding subgraphs in data graphs for a given query graph), they have been independently researched without clear reason. We argue that a subgraph isomorphism algorithm can be easily modified to handle the graph homomorphism, which is the RDF pattern matching semantics, by just removing the injectivity constraint. In this paper, based on the state-of-the-art subgraph isomorphism algorithm, we propose an in-memory solution, Turbo
HOM++
, which is tamed for the RDF processing, and we compare it with the representative RDF processing engines for several RDF benchmarks in a server machine where billions of triples can be loaded in memory. In order to speed up Turbo
HOM++
, we also provide a simple yet effective transformation and a series of optimization techniques. Extensive experiments using several RDF benchmarks show that Turbo
HOM++
consistently and significantly
outperforms the representative RDF engines. Specifically, Turbo
HOM++
outperforms its competitors by up to
five
orders of magnitude.

There are the guidelines to estimate the shrinkage strain of concrete bridge structures for the high tensile strength-SCI in accordance with PN-EN 1992-2. The article presents the results of experimental studies which aim was to analyze the course of shrinkage in two types of specimens made of different composition mixes. The studies have also made possible to verify the actual size of the shrinkage strain and designated ones on the basis of the PN-EN 1992-2.
Crystalline protein profiling and cry gene detection in Bacillus thuringiensis strains isolated during epizootics in Cydia pomonella L.
Authors: Konecka Edyta , Baranek Jakub , Kaznowski Adam
Published: July 2015

The composition of Bacillus thuringiensis crystalline inclusions was characterized in 18 strains: 12 isolates were obtained from the intestinal tract of Cydia pomonella larvae during epizootics, 2 isolates were cultured from Leucoma salicis larvae taken from their natural populations, and 4 reference strains. The number and molecular mass of B. thuringiensis crystalline proteins (Cry and Cyt) was estimated by the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The crystals contained 1-8 proteins with molecular masses of 36-155 kDa. The toxin profiles differed both quantatively and qualitatively. The B. thuringiensis MPU B9 isolate had the highest number and diversity of Cry toxins. The analysis of crystal composition by SDS-PAGE was insufficient to detect groups and subgroups of Cry proteins. We identified 20 groups and 3 subgroups of Cry and Cyt crystalline toxins. Only one epizootic strain harboured cry25. In single reference strains, the cry1H, cry10 and cry25 genes were found. We did not find any correlation between the occurrence of cry genes and electrophoretic protein profiles of crystalline toxins.
Mites (Acari) at the edges of bog pools in Orawa–Nowy-Targ Basin (S Poland), with particular reference to the Oribatida

Published: July 2015

Mites, and among them especially the Oribatida, are very abundant in bogs, being good bioindicators of various changes, but little is known about their reaction to heavy industrial exploitation of bogs. This study aimed to compare the acarofauna of the edges of small pools located in 2 bogs of Orawa-Nowy-Targ Basin (Kotlina Orawsko-Nowotarska), namely Łysa Puścizna (LP) and Bór Podczerwony (BP), degraded to different degrees by peat exploitation. The area of bog LP has decreased since the end of the 19th century by 34%, while that of BP has decreased during this time drastically (by 68%). Water in both studied pools differed from that in natural bogs, reported in the literature, especially in pH, colour, and oxygen conditions (COD and BOD5), and these differences were more pronounced at BP. The abundance of mites was similar to that observed in natural bogs, and the Oribatida dominated among mites, constituting over 99% of them. The species diversity of Oribatida was low in both pools, but especially in pool BP. In both bogs the aquatic species were the most abundant due to the wet study season. The species structure of Oribatida differed, however, from that reported from natural bogs as well as from each other. At the less degraded bog LP the most abundant was Hydrozetes lacustris (D = 69%), while at bog BP, with worse water parameters, Trimalaconothrus maior highly dominated (D = 93%). This suggests that the latter species is very tolerant to water parameters, being a successful coloniser of degraded bogs.
Preparation of Lewis acid ionic liquids for one-pot synthesis of benzofuranol from pyrocatechol and 3-chloro-2-methylpropene

Published: July 2015

Several Lewis acid ionic liquids (LAILs) with different acidic scales were synthesised and used as catalysts for the synthesis of benzofuranol by condensation of pyrocatechol and 3-chloro-2- methylpropene in one pot. The catalytic activity of these ionic liquids was correlated with their Lewis acidity. Low to moderate conversion with excellent selectivity to benzofuranol was obtained in the presence of the appropriate LAILs. Compared to the two-step synthetic method currently used in industry, a higher yield plateau (81.1 %) of benzofuranol was achieved in the presence of [BMIm][AlCl
Transcriptional profiling of bovine muscle-derived satellite cells during differentiation in vitro by high throughput RNA sequencing
Authors: Tong Hui Li , Yin Hong Yan , Zhang Wei Wei , Hu Qian , Li Shu Feng , Yan Yun Qin , Li Guang Peng
Published: July 2015

In this study, we utilized high throughput RNA sequencing to obtain a comprehensive gene expression profile of muscle-derived satellite cells (MDSCs) upon induction of differentiation. MDSCs were cultured in vitro and RNA was extracted for sequencing prior to differentiation (MDSC-P), and again during the early and late differentiation (MDSC-D1, and MDSC-D3, respectively) stages. Sequence tags were assembled and analyzed by digital gene expression profile to screen for differentially expressed genes, Gene Ontology annotation, and pathway enrichment analysis. Quantitative real-time PCR was used to confirm the results of RNA sequencing. Our results indicate that certain of genes were changed during skeletal muscle cell development, cell cycle progression, and cell metabolism during differentiation of bovine MDSCs. Furthermore, we identified certain genes that could be used as novel candidates for future research of muscle development. Additionally, the sequencing results indicated that lipid metabolism might be the predominant cellular process that occurs during MDSC differentiation.

The solubility of electrospun poly(vinyl alcohol) nanofiber mats (PVAES-NFM) is strongly influenced by loading with nanocellulose (NC). The NC was derived from hemp shives obtained by steam explosion autohydrolysis followed by water and alkaline extraction, ball milling, and ultrasonication treatments. It was demonstrated for the first time that PVAES-NFM does not disintegrate in aqueous medium after simple adding of NC without any additional chemical or physical modification (PVAES-NFMNC). The structural and thermal studies on PVAES-NFMNC indicated that enhanced stability in aqueous medium can be explained by interactions between surface groups of NC and PVA macromolecules as well as by reinforcing the effect of NCs. The experimental findings could be important for filtration applications in environments with high relative humidity.
The role of the Lowe syndrome protein OCRL in the endocytic pathway
Authors: Sharma Shruti , Skowronek Agnieszka , Erdmann Kai Sven
Published: July 2015

Mutations of the inositol-5-phosphatase OCRL cause Lowe syndrome and Dent-II disease. Both are rare genetic disorders characterized by renal defects. Lowe syndrome is furthermore characterized by defects of the eye (congenital cataracts) and nervous system (mental disabilities, hypotonia). OCRL has been localised to various endocytic compartments suggesting impairments in the endocytic pathway as possible disease mechanism. Recent evidence strongly supports this view and shows essential roles of OCRL at clathrin coated pits, transport of cargo from endosomes to the trans-Golgi network as well as recycling of receptors from endosomes to the plasma membrane. In particularin vitroandin vivoevidence demonstrates an important role of OCRL in recycling of megalin, a multi-ligand receptor crucial for reabsorption of nutrients in the proximal tubulus, a process severely impaired in Lowe syndrome patients. Thus defects in the endocytic pathway are likely to significantly contribute to the kidney phenotype in Lowe syndrome and Dent-II disease.
Variable Selection for Confounder Control, Flexible Modeling and Collaborative Targeted Minimum Loss-Based Estimation in Causal Inference
Authors: Schnitzer Mireille E. , Lok Judith J. , Gruber Susan
Published: July 2015

This paper investigates the appropriateness of the integration of flexible propensity score modeling (nonparametric or machine learning approaches) in semiparametric models for the estimation of a causal quantity, such as the mean outcome under treatment. We begin with an overview of some of the issues involved in knowledge-based and statistical variable selection in causal inference and the potential pitfalls of automated selection based on the fit of the propensity score. Using a simple example, we directly show the consequences of adjusting for pure causes of the exposure when using inverse probability of treatment weighting (IPTW). Such variables are likely to be selected when using a naive approach to model selection for the propensity score. We describe how the method of Collaborative Targeted minimum loss-based estimation (C-TMLE; van der Laan and Gruber, 2010 [27]) capitalizes on the collaborative double robustness property of semiparametric efficient estimators to select covariates for the propensity score based on the error in the conditional outcome model. Finally, we compare several approaches to automated variable selection in low- and high-dimensional settings through a simulation study. From this simulation study, we conclude that using IPTW with flexible prediction for the propensity score can result in inferior estimation, while Targeted minimum loss-based estimation and C-TMLE may benefit from flexible prediction and remain robust to the presence of variables that are highly correlated with treatment. However, in our study, standard influence function-based methods for the variance underestimated the standard errors, resulting in poor coverage under certain data-generating scenarios.
K Niektorým Aspektom Termínu „Archaizmus “
Authors: Kováčová Viera
Published: July 2015

Main focus of this paper is the issue of notional variability of the term “archaism” which occurs in historical-linguistic and dialectological works with a common denominator - dialects. The basis of the registered notional variability (1. Linguistic phenomenon which carries over from an earlier linguistic period - residual archaism; 2. Dialectal phenomenon which represents older state of language - relict archaism 3. Dialectal phenomenon which is currently receding - synchronic, structural archaism) lies in differences resulting from diachronic (the age of the linguistic phenomenon, diachronic resultativity, residuality/relictness) and synchronic (obsolescence of the linguistic phenomenon, synchronic processuality) approach to the language and its dynamics. The variability of the term archaism according to the approach used (the aspect of the national language, its development vs. the aspect of dialectal system and its structure) is illustrated on the example of linguistic phenomena characteristic for Sotak dialects of the north-eastern Zemplín. During the process of selection of examples from Sotak dialects the fact that the structure of this dialectal system includes, in a concentrated form, linguistic phenomena reflecting an older developmental state of the Slovak language (archaisms from the point of view of national language and its development) was taken into consideration.
Data Stream Quality Evaluation for the Generation of Alarms in the Health Domain

Published: July 2015

The use of sensors has had an enormous increment in the last years, becoming a valuable tool in many different areas. In this kind of scenario, the quality of data becomes an extremely important issue; however, not much attention has been paid to this specific topic, with only a few existing works that focus on it. In this paper, we present a proposal for managing data streams from sensors that are installed in patients’ homes in order to monitor their health. It focuses on processing the sensors’ data streams, taking into account data quality. In order to achieve this, a data quality model for this kind of data streams and an architecture for the monitoring system are proposed. Moreover, our work introduces a mechanism for avoiding false alarms generated by data quality problems.
Computational psycholinguistic analysis and its application in psychological assessment of college students
Authors: Kučera Dalibor , Havigerová Jana M.
Published: July 2015

The paper deals with the issue of computational psycholinguistic analysis (CPA) and its experimental application in basic psychological and pedagogical assessment. CPA is a new method which may potentially provide interesting, psychologically relevant information about the author of a particular text, regardless of the text’s factual (semantic) content and without the need to obtain additional materials. As part of our QPA-FPT research we studied the link between the linguistic form of a text by Czech college students and their personality characteristics obtained from a psychodiagnostic test battery. The article also discusses the basis of the method, opportunities for practical application and potential use within psychological and pedagogical disciplines
Asking better questions! A review of the pedagogical strategies used in one senior level award in Scotland
Authors: Thorburn Malcolm , Seatter Katrina
Published: July 2015

Previous related research on teaching effectiveness in one senior level award - Higher Still Physical Education (HSPE) in Scotland - revealed a number of extended challenges in adopting the practical experiential teaching and learning approaches advised. However, these studies were restricted by lack of observation of teaching and learning in action and of detailed analysis of the types and timings of questions asked. The present study addressed these limitations. Data were collected through observations of teaching, questionnaire responses on the uses of discussions by pupils and teachers and semi-structured teacher interviews. Findings revealed that there were encouraging signs of a broad range of purposeful question techniques being used in practical sessions. However, there was still a lack of full teacher trust in these approaches, despite high pupil endorsement for their usage. We conclude that perceived subject content and external assessment demands continue to constrain pedagogical strategies in HSPE.
Probabilistic and statistical properties of moment variations and their use in inference and estimation based on high frequency return data
Authors: Lee Kyungsub
Published: July 2015

We discuss the probabilistic properties of the variation based third and fourth moments of financial returns as estimators of the actual moments of the return distributions. The moment variations are defined under non-parametric assumptions with quadratic variation method but for the computational tractability, we use a square root stochastic volatility model for the derivations of moment conditions for estimations. Using the S&P 500 index high frequency data, the realized versions of the moment variations is used for the estimation of a stochastic volatility model. We propose a simple estimation method of a stochastic volatility model using the sample averages of the variations and ARMA estimation. In addition, we compare the results with a generalized method of moments estimation based on the successive relation between realized moments and their lagged values.
Materia mystica. Próba introspekcji w kolorach złota i czerni* / Materia Mystica. An Introspection in Black and Gold
Authors: Snoch-Pawłowska Alicja
Published: July 2015

The article is an attempt to combine reflection on the mystical side of artistic activity with the author’s self-comment on her creative work in graphic art. The discourse shows multi-aspectual thoughts on the secret of the act of creation and the matter itself that serves art, based on the philosophical background of different religious, cultural and worldview traditions; it also touches upon the sphere of self-cognition, symbolism, and transcendence. The author’s narrative is accompanied by the thoughts of inter alia William Blake, Samuel Coleridge, Stanisław Fijałkowski, Hildegard of Bingen, Carl Gustav Jung, Kabir, Wassily Kandynsky, Paul Klee, Czesław Miłosz, Meister Eckhard, Rainer Maria Rilke, Andrzej Strumiłło, St. John of the Cross, and Zhuangzi. These considerations are combined with the analytical explication of the author’s selected works and with an attempt to introspectively look into herself.

The author examines the following: understanding of the concept and phenomenon of matter (Materia - proch ziemi i kwantowa pustka [Matter - the Dust of Earth and Quantum Void]); mystical and spiritual aspects of art (Mistyka - ulotność wizji i realność duchowości [Mysticism - Transience of Vision and the Reality of the Spiritual]); the world (identified with the matter of creation) of inner experiences of her own artistic imagination (Materia tworzenia [Matter of Creation]); symbolic-formal features of her own graphic works (W granicach formy [Within the Form]); and the unfathomable problem of cognition and self-cognition through art (Laboratorium sztuki i sztuka przemiany [Laboratory of Art and the Art of Transformation]).
