    Transformations in the Santa Catarina labor market: the reality of youth

    Unemployment and informality have become fundamental to the survival of the current model and youth is one of the segments that suffers most from these evils. The 1990s is marked by the advent of neoliberal politics, which promoted several changes in the working world. As a result Brazil and the State of Santa Catarina also suffered the effects of these changes. The objective of this article is to build a brief diagnosis of the young, the labor market and its reality in the state of Santa Catarina. Here we focused on the idea of how youth, or a large part of it, comes across the face of significant difficulties upon their insertion into the labor market. These difficulties are revealed in rates of unemployment, informality, the low pay and other forms of existing precariousness in labor relations

    Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

    We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2

    Restoration and Reconstruction of AVHRR Images

    This paper describes the design of small convolution kernels for the restoration and reconstruction of Advanced Very High Resolution Radiometer (AVHRR) images. The kernels are small enough to be implemented efficiently by convolution, yet effectively correct degradations and increase apparent resolution. The kernel derivation is based on a comprehensive, end-to-end system model that accounts for scene statistics, image acquisition blur, sampling effects, sensor noise, and postfilter reconstruction. The design maximizes image fidelity subject to explicit constraints on the spatial support and resolution of the kernel. The kernels can be designed with h e r resolution than the image to perform partial reconstruction for geometric correction and other remapping operations. Experiments demonstrate that small kernels yield fidelity comparable to optimal unconstrained filters with less computation

    New insights into the phylogeny of the dark-spored Myxomycetes (Amoebozoa: Conosa: Myxogastria: Fuscisporidia) and polyphyly of the genus Stemonitis

    About a thousand described species of Myxomycetes, colloquially named slime moulds, are present in most terrestrial habitats. Molecular environmental sampling has revealed that a significant proportion of sequences could not be assigned to known species, with some specific groups showing a high hidden diversity. One such group included Stemonitis and allied genera, with only a few closely related reference sequences from known species and many distantly related sequences from environmental sampling. To improve the phylogeny and help define genera in this lineage, we provided nine new small-subunit ribosomal RNA gene sequences of Stemonitis and allied genera, along with microscopy observations. We showed that the genus Stemonitis is polyphyletic, clearly separated into two groups, with the main distinguishing feature being spore ornamentation. The first group included the type species Stemonitis fusca, and was characterized by reticulated spores, while the second contained species with warted spores (e.g. S. flavogenita and S. axifera) and many undetermined environmental sequences. In addition, we show that the related genera Stemonitopsis, Stemonaria and Symphytocarpus were polyphyletic and that their circumscription was based on inconsistent characteristics. Instead, representatives of these genera clustered into the two clades according to their spore ornamentation. Our study provides a first insight into the genetic diversity of Stemonitis and allied genera, and proposes spore ornamentation as an evolutionary informative feature to distinguish genera in this group

    Um panorama da economia solidária em Santa Catarina, Brasil

    The Solidarity Economy theme has been gaining ground both in the academic sphere and in the agenda of the various actors. Not coincidentally, the aim of this study was to present a Solidarity Economy overview in the State of Santa Catarina, inserted in a contradictory socio-economic context: while, on one hand, the state has indicators that show a higher degree of development, on the other, it reveals significant disparities among their regions. To achieve this objective, the Solidarity Economy Atlas for the years 2007 and 2013 were examined. The questioning reveals that Santa Catarina’s development is marked by inequality and that the Solidarity Economy appears as an alternative for a significant portion of the population. By comparing the data in the observed period, it was evident that the Solidarity Economy practices have been strengthened over time, and they are not only an alternative to workers but also contribute to local and regional development. Moreover, such actions are configured as a space of selfmanagement practice and, therefore, of potential generalization of this behavior in society.O tema Economia Solidária vem ganhando espaço tanto na esfera acadêmica quanto na agenda dos mais diversos atores. Não por acaso, o objetivo deste trabalho foi apresentar um panorama da Economia Solidária no Estado de Santa Catarina, inserido em um contexto socioeconômico contraditório: se por um lado o Estado apresenta indicadores que demonstram um maior grau de desenvolvimento, por outro, revela desigualdades significativas entre suas regiões. Para a consecução deste objetivo, foram examinados os resultados dos Atlas de Economia Solidária referente aos anos de 2007 e 2013. A problematização revela que o desenvolvimento catarinense é marcado pela desigualdade e que a economia solidária surge como alternativa para uma parcela significativa da população. Através da comparação dos dados no período observado se evidenciou que as práticas da Economia Solidária vêm se fortalecendo ao longo do tempo e que constituem, não só uma alternativa aos trabalhadores, mas também contribuem para o desenvolvimento local e regional. Ademais, tais ações se configuram como um espaço de prática da autogestão, e, portanto, de possível generalização deste comportamento na sociedade
