A ferrovia no Vale do Itajaí
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Urbanismo, História e Arquitetura da CidadeO tema desta dissertação é uma análise dos fatos históricos relacionados ao processo de implantação e à posterior desativação da EFSC no Vale do Itajaí, destacando os principais agentes do processo e a conseqüência de suas ações no domínio geográfico e social. Esta pesquisa tem sua relevância social e acadêmica como instrumento de pesquisa e de memória baseado na organização dos fatos históricos desencadeados em torno dos transportes no Vale do Itajaí, com foco para o transporte ferroviário, uma vez que há pouca publicação e pesquisa sobre a EFSC. O trabalho foi referenciado pela análise das relações sociais sob os conceitos de Santos (1991), de fatos históricos registrados em periódicos, documentos escritos, fotográficos e cartográficos, entrevistas e, quando necessário, pela busca da contextualização dentro dos acontecimentos nacionais e internacionais, para melhor esclarecimento dos fatos em escala local e regional. Além disso, esta pesquisa usou como referência a análise e os conceitos de Mumford, em sua obra A Cidade na História, abordando o processo de transformações urbanas decorrente do desenvolvimento das cidades e seus principais agentes. Conceitos de outros autores, como Villaça, Lefebvre e Halbwachs são igualmente suportes teóricos deste trabalho. A ferrovia fez parte dos planos das lideranças locais, desde as primeiras décadas de história da fundação dos núcleos urbanos na região da bacia do Itajaí, como questão básica para o desenvolvimento econômico da região. The theme of this thesis is an analysis of historical facts related to the process of implantation and further disabling of EFSC (Estrada de Ferro Santa Catarina) in the region of Vale do Itajaí, State of Santa Catarina, highlighting the main agents of the case and the consequences of their actions both on geographical and social domain. This research has a social and academic relevance as a tool for further search and memory since it presents the organization of historical facts regarding transport in the region of Vale do Itajaí, with a focus on railway transportation, especially EFSC, from which little research sources and publications can be found. The work is referenced by an analysis of social relations according to the concepts of Santos (1991); historical facts recorded in journals, written, photographic, cartographic documents; and interviews. It includes, also, some search on the context of national and international events in order to offer a better understanding of the facts in a local and regional scale. Additionally, this research used as a reference to the concepts shown an analysis registered by Mumford in his book "A Cidade na História", around the process of urban transformations resulting from the development of cities and their key players. Concepts of other authors, as Villaça, Lefebvre and Halbwachs are also devices of this theoretical work. The railway took part of the local leaders' plans since the first decades of the history of the foundation of urban areas located at the basin of the Itajaí River. It was, at that time, a basic need for the economic development of the region

Carpopropodus two-segmented in thoracic endopods 1–2, 8, or three-segmented in endopods 3–7, except that endopods 6, 7 may be twosegmented in some females. Basal segment occupies 0.4–0.5 times total length of carpopropodus of endopod 3. Pleopod 1 representing a stout, bilobate plate in both sexes. Sympod of male pleopod 4 with endite reduced to a weak medial hump or missing. Exopod with basal segment occupying 56–63% total length. Endopod reduced to lobe with 10–16% sympod length; lobe apically with one long, barbed seta and more proximally with additional 4–6 shorter, barbed setae. Endopod of uropods 0.6–0.8 times as long as exopod. Telson spatulate, length 1.9–2.1 times maximum width near basis; median portion with concave lateral margins, terminal portion triangular with rounded tip. Proximal 52–64% of lateral margins smooth; distal portion of each margin with continuous series of 5–11 acute spines, this series extending up to the corner with the triangular apical portion.

Endopod 8 (when stretched) reaching backwards at most to end of pleonite 3 and forwards to maxillula; its carpopropodus measures 0.4–0.5 times telson length. THORACOPODS OF FEMALES (Figs 7A, 8G). Basal plate of exopod 8 with short to indistinct latero-distal expansion; its flagellum only 8-segmented. Oostegites of thoracopods 7–8 densely fringed with setae, together forming a large brood chamber. Thoracopod 6 (Fig. 7A) with rudimentary oostegite bearing 1–2 long setae at apex.

Tegmen moderately, though always distinctly convex; fundus weakly concave. Sagittal section very similar to that figured by Wittmann et al. (1993: fig. 6P) for Heteromysis formosa S.I. Smith, 1873. Statolith formula 2 + 3 + 1 + (8–13) = 14–19. NAUPLIOID LARVAE (Fig. 8M–N). Smooth cuticle all around, except for a pair of minute furcal processes and a number of minute setae on the blunt end of the abdomen. Distribution and habitat So far only known from euhaline, sublittoral waters of Curaçao (12° N), where the mysids occur in swarms hovering during daytime around and between corals.Published as part of Wittmann, Karl J. & Wirtz, Peter, 2019, Revision of the amphiamerican genus Mysidium Dana, 1852 (Crustacea: Mysida: Mysidae), with descriptions of two new species and the establishment of two new subgenera, pp. 1-48 in European Journal of Taxonomy 495 on pages 16-23, DOI: 10.5852/ejt.2019.495, http://zenodo.org/record/258486

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
