Empresas recuperadas por trabalhadores no Brasil e na Argentina

Este artigo é resultado de uma tese de doutorado que teve como objetivo identificar inovações no campo da organização do trabalho produzidas pelas experiências de empresas recuperadas por trabalhadores no Brasil e na Argentina. A tese central defendida é a de que as limitações impostas pela hegemonia do modo de produção capitalista não encerram a possibilidade de construção de novas relações sociais de produção. Os cinco estudos de caso realizados e a experiência de levantamentos da totalidade das experiências de empresas recuperadas nos dois países forneceram elementos que permitiram problematizar em vários aspectos a organização capitalista do trabalho e, por meio de uma crítica prática, como sugere Rebón (2007), propiciaram a reflexão sobre a possibilidade de superação do modelo hegemônico, que não passa apenas pela inovação no interior das organizações, mas também da relação dessas empresas com seus territórios.

Differential involvement of the anterior temporal lobes in famous people semantics

The ability to recognize a famous person occurs through semantic memory. Previous neuroimaging studies have shown that the anterior temporal lobes (ATLs) are involved in the recognition of famous people. However, it is still a matter of debate whether the semantic processing of names or pictures of famous people has an impact on the activation of ATLs. The aim of this study was to explore the pattern of activation associated with a semantic processing of famous people based on face and written name stimuli. Fifteen healthy young individuals participated in our fMRI study, in which they were asked to perform a semantic categorization judgment task, based on profession, of visually presented pictures, and names of famous people. Neuroimaging findings showed a common pattern of activation for faces and names mainly involving the inferior frontal regions, the posterior temporal lobe, the visual cortex, and the ATLs. We found that the comparison names vs. pictures lead to significant activation in the anterior superior temporal gyrus. On the other hand, faces vs. names seemed associated with increased activation in the medial ATL. Moreover, our results demonstrated that the functional connectivity network anchored to the medial ATL, compared to the anterior STG, is more connected to the bilateral occipital lobe and fusiform gyrus that are regions implicated in the visual system and visual processing of faces. This study provides critical evidence of the differential involvement of ATL regions in semantics of famous people

Who are they and what do they do? Profile of allied health professionals working with people with disabilities in rural and remote New South Wales

Objective: To explore the characteristics of allied health professionals (AHPs) working with people with disabilities in western New South Wales. Design: A cross-sectional survey was conducted using an online questionnaire. Setting: Rural western NSW. Participants: AHPs including physiotherapists, speech pathologists, occupational therapists and psychologists (“therapists”) working with people with disabilities. Main outcome measure: Questionnaire Results: The majority of respondents were female (94%), with a mean age of 39 years; average time since qualification was 14 years; mean years in current position was 6. Most worked with people with a lifelong disability. Two-thirds reported family ties kept them in rural areas; 71% grew up in a rural/remote area. Most participants (94%) enjoyed the rural lifestyle and 84% reported opportunities for social interaction as good or very good. Participants with dependent children were less likely to cease working in western NSW within 5 years than those without dependent children (p<0.05). Conclusions: The characteristics of therapists working with people with disabilities in rural NSW were identified. Overall working, but also social, conditions and community attachment were important for this group. Understanding the workforce will contribute to policy development to meet increasing demands for therapy services.The project is jointly funded through the National Health and Medical Research Council ‘Partnerships for Better Health’ scheme, by the National Health and Medical Research Council (ID 571446) and NSW Government Family and Community Services – Ageing, Disability and Home Care (Western Region)

Evaluation sur 24 mois de la pulpotomie à l’oxyde de zinc-eugénol sur des canines temporaires saines ou cariées

Pulpotomy is the most performed and controversial therapeutic in pediatric dentistry. Since formocresol is known to have a toxic effect on living tissues, plus a mutagenic and carcinogenic potential with a systemic uptake of formocresol via pulpotomized teeth, other alternative products have been investigated. Twenty-five decayed primary canines and twenty-five healthy primary canines necessitating disking for orthodontic purposes were pulpotomized using non modified Zinc Oxide Eugenol. The effects of this material were evaluated both clinically and radiographically. Post operative control examinations were performed at 1, 6, 12 and 24 months trying to detect spontaneous or stimulated pain, pathological tooth mobility, abscesses or fistulas, internal or external pathological tooth resorption, periapical bone destruction, or canal obliteration. Pain was absent at 24 months post operatively. Half of the treated canines presented with a mobility, while internal and external resorptions were more frequent in decayed teeth and their number increased with time. On the other hand, abscesses and fistulas were equally found in both treated groups. The observations were compared to others related to formocresol ferric sulfate, MTA, and laser pulpotomies, using the binominal law, or the comparative test of an observed proportion to a reference proportion. In this study, and based on the excessive negative results in both groups, we demonstrated that non fixative pulpotomies on temporary canines were a promising techniqueLa pulpotomie, est la thérapeutique pulpaire la plus couramment réalisée et la plus controversée en médecine dentaire pédiatrique. Les craintes concernant la diffusion systématique et la potentielle toxicité, allergénicité, carcinogénicité, en mutagénicité du formaldéhyde ont conduit à rechercher des alternatives à ce produit. Afin d’évaluer, selon des critères cliniques et radiologiques, l’action de l’oxyde de zinc-eugénol non modifié, l’une des alternatives au formocrésol, 25 canines temporaires cariées et 25 canines temporaires nécesitant un meulage dimensionnel dans le cadre de traitements interceptifs de dysharmonies dento-maxillaires (DDM) mineures du secteur antérieur, ont subi une pulpotomie à l’aide de ce matériau. Les contrôles post-opératoires ont été réalisés à 1, 6, 12 et 24 mois, à la recherche de douleur spontanée ou provoquée, de mobilité dentaire pathologique, d’abcès ou de fistule, de résorption radiculaire interne ou externe pathologique, de destruction osseuse péripicale ou d’oblitération canalaire. La douleur était inexistante à 24 mois. La moitié des canines traitées présentaient une mobilité alors que les résorptions internes et externes ont été rencontrées plus fréquemment dans le groupe « Carie » où le nombre augmentait avec le temps. Par ailleurs, le nombre d’abcès sans fistule s’observait de la même façon dans les deux groupes. Ces observations ont été comparées à celles relatives à la pulpotomie au formocrésol, au sulfate ferrique, au MTA et au laser, en utilisant le test de la loi binomiale ou le test de la comparaison d’une proportion observées à une proportion de référence. L’abondance de résultats négatifs dans les deux groupes démontre fortement que la pulpotomie non fixatrices sur des canines temporaires n’est pas une technique prometteuse

Erodibility of soil above the groundwater level: some test results

The paper presents a study on erodibility of soil above the groundwater level where the water is in tension. Such soils particularly clays are very sensitive to moisture and temperature changes and can be eroded significantly by water flow. The erosion of clay and sand samples from the US National Geotechnical Experimentation Site at Texas A&M University is studied. Two sets of experiments are done with the clay and the sand. The first set was performed on sample collected in November 2014 and the second set on samples from June 2014. The depth of the samples varied from 0.6 to 3.6 m where water content and density changes. A series of erosion tests was performed in the Erosion Function apparatus (EFA) with the intact clay and then with the sand reconstructed to the field density and field water content. The erosion tests are performed at different flow velocities varying from 0.5 m/s to 5.5 m/s. The erodibility is quantified by the relationship between the erosion rate and the water velocity called the erosion function. Some relationships between the critical velocity and common soil properties are discussed. The collapse of the clay structure when inundated (soaking) is studied
