A formação da colônia alemã Teresópolis e a atuação da igreja católica (1860 - 1910)
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-graduação em HistóriaEste trabalho aborda aspectos da imigração alemã para o Brasil, as articulações que antecederam e fundamentaram a fundação da Colônia Teresópolis e, nela, a atuação da Igreja Católica. Outrossim, ressalta os desafios institucionais da consolidação do processo católico de romanização, num recorte cronológico que compreende o período de 1860 a 1910. Nesse contexto imigratório tornam-se salientes certos aspectos da atuação da Igreja, consubstanciados na ação pastoral desenvolvida pelos padres Guilherme Roer, Francisco Topp e pelos franciscanos, através da assistência religiosa aos imigrantes alemães instalados na Colônia Teresópolis e imediações

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

The location of diapycnal mixing and the meridional overturning circulation
No full textThe large-scale consequences of diapycnal mixing location are explored using an idealized threedimensional model of buoyancy-forced flow in a single hemisphere. Diapycnal mixing is most effective in supporting a strong meridional overturning circulation (MOC) if mixing occurs in regions of strong stratification, that is, in the low-latitude thermocline where diffusion causes strong vertical buoyancy fluxes. Where stratification is weak, such as at high latitudes, diapycnal mixing plays little role in determining MOC strength, consistent with weak diffusive buoyancy fluxes at these latitudes. Boundary mixing is more efficient than interior mixing at driving the MOC; with interior mixing the planetary vorticity constraint inhibits the communication of interior water mass properties and the eastern boundary. Mixing below the thermocline affects the abyssal stratification and upwelling profile, but does not contribute significantly to the MOC through the thermocline or the ocean’s meridional heat transport. The abyssal heat budget is
dominated by the downward mass transport of buoyant water versus the spread of denser water tied to the properties of deep convection, with mixing of minor importance. These results are in contrast to the widespread expectation that the observed enhanced abyssal mixing can maintain the MOC; rather, they suggest that enhanced boundary mixing in the thermocline needs to be identified in observations
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Numerical evidence against reversed thermohaline circulation in the warm Paleocene/Eocene ocean
No full textThe question of whether deep water formation might have occurred in subtropical latitudes in the early Cenozoic is examined through use of a global ocean model forced by mixed boundary conditions. Zonal mean surface temperatures and wind stresses are derived from an atmospheric general circulation model (AGCM) simulation of the warm Paleocene/Eocene boundary interval (~55 Ma) and are held constant for a series of sensitivity tests. The control case for moisture flux (evaporation minus precipitation, E-P), also derived from the AGCM, is perturbed so that the subtropical evaporation increases and high latitude precipitation increases. A dramatic response is seen in the temperature and salinity structure of the model ocean, but the perturbation does not result in deep convection in subtropical latitudes. In all cases, bottom water is formed in the southern high latitudes and the global meridional overturning is characterized by a strongly asymmetric
circulation. No multiple equilibria have been found for any particular E-P configuration. In the most extreme case (5 x the control E-P), the model oscillates between meridional overturning circulation “on” and “off.” Shorter-lived thermohaline slowing and reinvigoration is observed as a transient response under less extreme E-P perturbations. Despite the high evaporation implied in the perturbation experiments, mean mixed layer salinities in the subtropics do not rise much above the control case due to efficient removal of salt (and heat) through deepened subduction beneath the subtropical gyres. The sensitivity of the results to the parameterization of continental runoff and the specified diapycnal mixing coefficient (Kv) are also examined. Distributing runoff purely zonally, rather than globally, has approximately the same effect as a 50% increase in the strength of the hydrologic cycle. Decreasing Kv to 0.3 cm2 s-1 from the standard value of 1.0 cm2
s-1 increases the sensitivity to an increased hydrologic cycle considerably, but in no case does low latitude deep water formation occur, indicating that subtropical bottom water formation is implausible in a model with some degree of realism. These experiments support changes in moisture flux as a mechanism for ocean warming (largely in the thermocline through intermediate water depths), but the process involved is deepened subtropical subduction and not subtropical deep
water formation
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
