Una historia actual que explora las relaciones sociales y las cuestiones relativas a las futuras orientaciones en la experimentación científica. La cuestión de confianza se plantea también como un factor clave. Frankie Stein vive con su hermano, David, y su papá. Su padre es un ingeniero genético que investiga en un gran laboratorio en lo alto de la colina. El laboratorio cuenta con un montón de guardias de seguridad y se parece algo a una de esas viejas películas de horror. Sus compañeros se burlan de ella y dicen que su padre está creando un mundo de monstruos. El padre está siempre demasiado ocupado para hablar y ella comienza a preguntarse si realmente está trabajando por el bien de la humanidad. Un día, David roba un tubo de ensayo del laboratorio. Él y Frankie deciden repartirlo entre ellos y hacer algunos experimentos en secreto. Frankie acaba por producir una encantadora, alegre criatura llamada Monnie, que le gusta silbar y es experta en mutarse. Al instante Monnie se convierte en su mejor amiga y Frankie comienza a sentirse importante y valiosa casi por primera vez en toda su vida. Frankie no quiere renunciar a Monnie pero Monnie es sólo una extraña creación de un tubo de ensayo.

El desembre de 2008 l’Observatori d’Ètica Aplicada a la Intervenció Social (OEAIS) va publicar Força i violència en educació social. En Pere i en Josep, anàlisi d’un cas pràctic sobre els límits de la força física en un Centre Residencial d’Acció Educativa (CRAE). Aquest informe partia d’una situació real ocorreguda a Catalunya en la qual un educador social que treballava en un CRAE havia donat una bufetada a un noi del centre, el pare l’havia denunciat i en la sentència el jutge va considerar que l’acció no era punible. Arran d’aquest i altres fets, en la normativa i en els protocols dels CRAE de Catalunya es va establir que en cap cas es podia donar una bufetada als nois i noies que hi vivien i que en una situació límit, els professionals de l’educació han de fer una contenció física o avisar a la policia o al servei hospitalari d’urgències

Based on interviews with diplomats from a representative cross-section of nine member states and members of the EEAS itself, the research findings of this EPIN Working Paper confirm long-standing traditions and member state perceptions of cooperation with European institutions. The paper also reveals new aspects of the intergovernmental method of foreign policy shaping and making in the European Union; in particular how different national positions can positively or negatively affect the consolidation of the EEAS and the role of the EU as an international actor. As such, the Working Paper makes an original contribution to the existing literature on one of most discussed actors in the European Union’s post-Lisbon architecture in the domain of EU external action.

This paper investigates the characteristics of unaccusative verbs in Italian with respect to the consistency with which these verbs select the auxiliaries ‘be’ (essere) and ‘have’ (avere) in compound tense forms. The study builds on the gradient approach to split intransitivity (Sorace 2000) by exploring the behaviour of 29 intransitive Italian verbs with respect to their core-peripheral features: auxiliary selection acceptability ratings and associated variance measures. Although there is clear support for the gradient approach in relation to the general order of semantic categories along the unaccusativity gradient, the results reveal that the ordering of subclasses within the Change group conflict with that currently proposed in the literature. In addition, the findings demonstrate the aspectual and lexical semantic characteristics of internally-caused change-of-state verbs in Italian require further investigation before their auxiliary selection behaviour can be properly understood. Furthermore, contrary to the gradient account, Existence verbs, the most stative and therefore the most peripheral subclass in the unaccusativity hierarchy, exhibit behaviour more characteristic of core unaccusative verbs. This study examines a wider range of semantic subclasses of unaccusative verbs than has hitherto been reported and identifies the core-peripheral boundary for Italian.1

Schwann cells (SCs) are the supporting cells of the peripheral nervous system and originate from the neural crest. They play a unique role in the regeneration of injured peripheral nerves and have themselves a highly unstable phenotype as demonstrated by their unexpectedly broad differentiation potential. Thus, SCs can be considered as dormant, multipotent neural crest-derived progenitors or stem cells. Upon injury they de-differentiate via cellular reprogramming, re-enter the cell cycle and participate in the regeneration of the nerve. Here we describe a protocol for efficient generation of neurospheres from intact adult rat and murine sciatic nerve without the need of experimental in vivo pre-degeneration of the nerve prior to Schwann cell isolation. After isolation and removal of the connective tissue, the nerves are initially plated on poly-D-lysine coated cell culture plates followed by migration of the cells up to 80% confluence and a subsequent switch to serum-free medium leading to formation of multipotent neurospheres. In this context, migration of SCs from the isolated nerve, followed by serum-free cultivation of isolated SCs as neurospheres mimics the injury and reprograms fully differentiated SCs into a multipotent, neural crest-derived stem cell phenotype. This protocol allows reproducible generation of multipotent Schwann cell-derived neurospheres from sciatic nerve through cellular reprogramming by culture, potentially marking a starting point for future detailed investigations of the de-differentiation process.

Purpose – Despite recent threats of economic contraction, China still offers attractive opportunities for foreign companies seeking to expand their business activities through joint venturing (JV) partnering entry strategies. Recent research has indicated a growing recognition of the importance of relational factors in JV partnering. The purpose of this paper is to build on recent research findings that identify critical relation success factors in JVs and explores these in the context of a Hong Kong-based civil aviation services company seeking to expand business activities in Greater China. Design/methodology/approach – While the extant management literature focuses primarily on factors relevant to the inter-partner relationship between partners in the formation stage of a joint venture, this research takes a dynamic stakeholder perspective in respect of the relevant relational factors over the evolution of a partnership. The research described in this paper is based on a case-based study that identifies and examines the relevance and importance of uniquely Chinese factors such as guanxi, renqing and mianzi in the specific context of a strategic partnering relationship. Findings – This phenomenological study provides empirical evidence of critical linkages of these to intrinsically Chinese notions of guanxi, mianzi and renqing – it links these to key strategic partnering success factors identified to be trust, conflict resolution, commitment and cooperation. This study thereby reinforces the importance of the uniquely Chinese relational context in cross-border JVs. Moreover, the research findings suggest that these factors underpin the dynamic bi-directional stakeholder relationship in a Sino-foreign strategic partnership. Originality/value – This study conceptually links the uniquely Chinese relational factors (guanxi, mianzi and renqing) to key success factors supporting the establishment of a strategic partnership in a Sino-foreign context; moreover, it contributes empirical evidence substantiating the proposed conceptual linkage.

A presente investigação pretende compreender as relações que envolvem a atuação do professor no laboratório de informática. O laboratório de informática representa neste trabalho um ambiente informatizado de aprendizagem na medida em que é usado por professores e alunos em atividades pedagógicas que propiciam processos de aprendizagem. A perspectiva da pesquisa visa, então, uma discussão a respeito da importância das intervenções pedagógicas do professor em ambientes informatizados de aprendizagem. O conceito de intervenção pedagógica, como um aspecto relevante na pesquisa, foi construído à luz da teoria freireana e de todo o processo investigativo. Os processos de aprendizagem também foram relevados neste trabalho, considerando que a relação de ensino é sempre vinculada às relações de aprendizagem. Neste sentido, foram feitos estudos na linha interacionista tendo como autores centrais Piaget e Vygotsky. Caracterizo o estudo na perspectiva da abordagem qualitativa, tendo como foco o estudo de caso do laboratório de informática. Os dados foram coletados através da observação participante e de entrevistas não estruturadas. Os resultados trazem indícios de que os processos de intervenção pedagógica podem ser um referencial nas atividades desenvolvidas naquele espaço. As relações estabelecidas em ambientes informatizados de aprendizagem, por professores e alunos, influenciam de forma singular na maneira como a aprendizagem se processa.

A leptospirose é uma grave zoonose associada às áreas de baixa renda dos centros urbanos. Embora roedores urbanos sejam considerados como principal reservatório para a leptospirose, o cão também pode desenvolver a doença e se tornar carreador assintomático. O objetivo do presente trabalho foi utilizar a metodologia estatística baseada na teoria de processos pontuais espaciais, buscando identificar a forma como se distribuem os cães sororreagentes para a leptospirose e seus determinantes de risco em uma vila na cidade de Curitiba. A análise do modelo possibilitou identificar as regiões de sobre-risco, onde o risco de soropositividade canina à leptospirose é significativamente maior. A relação significativa do efeito espacial no desenvolvimento da doença, além das variáveis estudadas, revela que não apenas um, mas a ação conjunta dos fatores relacionados ao animal, ao proprietário e ao ambiente influencia o risco maior da doença nos locais de maior efeito espacial. O resultado da análise indica claramente os territórios em maior risco na região da Vila Pantanal, possibilitando o planejamento de ações mais específicas e dirigidas a essas áreas em um contexto de vigilância da saúde.

Background: Leptospirosis is an important zoonotic disease associated with poor areas of urban settings of developing countries and early diagnosis and prompt treatment may prevent disease. Although rodents are reportedly considered the main reservoirs of leptospirosis, dogs may develop the disease, may become asymptomatic carriers and may be used as sentinels for disease epidemiology. The use of Geographical Information Systems (GIS) combined with spatial analysis techniques allows the mapping of the disease and the identification and assessment of health risk factors. Besides the use of GIS and spatial analysis, the technique of data mining, decision tree, can provide a great potential to find a pattern in the behavior of the variables that determine the occurrence of leptospirosis. The objective of the present study was to apply Geographical Information Systems and data prospection (decision tree) to evaluate the risk factors for canine leptospirosis in an area of Curitiba, PR.Materials, Methods & Results: The present study was performed on the Vila Pantanal, a urban poor community in the city of Curitiba. A total of 287 dog blood samples were randomly obtained house-by-house in a two-day sampling on January 2010. In addition, a questionnaire was applied to owners at the time of sampling. Geographical coordinates related to each household of tested dog were obtained using a Global Positioning System (GPS) for mapping the spatial distribution of reagent and non-reagent dogs to leptospirosis. For the decision tree, risk factors included results of microagglutination test (MAT) from the serum of dogs, previous disease on the household, contact with rats or other dogs, dog breed, outdoors access, feeding, trash around house or backyard, open sewer proximity and flooding. A total of 189 samples (about 2/3 of overall samples) were randomly selected for the training file and consequent decision rules. The remained 98 samples were used for the testing file. The seroprevalence showed a pattern of spatial distribution that involved all the Pantanal area, without agglomeration of reagent animals. In relation to data mining, from 189 samples used in decision tree, a total of 165 (87.3%) animal samples were correctly classified, generating a Kappa index of 0.413. A total of 154 out of 159 (96.8%) samples were considered non-reagent and were correctly classified and only 5/159 (3.2%) were wrongly identified. on the other hand, only 11 (36.7%) reagent samples were correctly classified, with 19 (63.3%) samples failing diagnosis.Discussion: The spatial distribution that involved all the Pantanal area showed that all the animals in the area are at risk of contamination by Leptospira spp. Although most samples had been classified correctly by the decision tree, a degree of difficulty of separability related to seropositive animals was observed, with only 36.7% of the samples classified correctly. This can occur due to the fact of seronegative animals number is superior to the number of seropositive ones, taking the differences in the pattern of variable behavior. The data mining helped to evaluate the most important risk factors for leptospirosis in an urban poor community of Curitiba. The variables selected by decision tree reflected the important factors about the existence of the disease (default of sewer, presence of rats and rubbish and dogs with free access to street). The analyses showed the multifactorial character of the epidemiology of canine leptospirosis.
