Cantando a insatisfação: os recursos linguístico-expressivos na obra de Gonzaguinha

A fim de motivar alunos dos Ensinos Fundamental e Médio a atentarem para o cunho expressivo dos fatos da língua e buscarem conhecer os grandes nomes da música nacional, este trabalho objetivou um estudo estilístico dos recursos linguístico-expressivos de textos musicais de Luiz Gonzaga do Nascimento Jr. o Gonzaguinha. Destacou-se, primeiramente, o viés social da música. Em seguida, pretendeu-se uma aproximação entre textos musicais e o conceito de poesia para, então, tratar mais cuidadosamente do papel didático da canção. Considerando a concepção de contracultura, defendida por Marilena Chauí (1990) como o contexto histórico do momento das produções musicais, partiu-se para explanações acerca da Estilística: sua história, seus âmbitos, seu alcance e possibilidades. Por fim, adentrou-se nas relações lingüísticas a partir de canções de tom ora de protesto inconformado, ora nacionalista-apaixonado do artista mencionado. Desenvolveu-se, portanto, uma abordagem estilística individual do autor a partir de apontamentos teóricos sobre aspectos sonoros, léxico-semânticos, morfossintáticos e enunciativos do processo discursivo expressivo. Com esse intento, elegeram-se composições que ilustraram as marcas lingüísticas e seu entrelaçamento com o plano do conteúdo

Lionfish dissection: techniques and applications

Dissection can provide unique information on the physiology, biology and ecology of organisms. This document describes protocols for dissecting lionfish (Pterois volitans and P. miles). Protocols were developed to provide guidance to trained research personnel. Lionfish are native to the Indo-Pacific, but have become established in marine habitats within the Western Atlantic, Gulf of Mexico and Caribbean. The protocols described within this document were designed to help standardize handling and dissection methodologies for these species, with the goal of improving the coordination of research (e.g., Lionfish Tissue Repository; Appendix V). We focus on dissection methods, which yield data that contribute to our understanding of lionfish biology and ecology. By pairing dissection information with environmental and biotic data, researchers and managers can better understand lionfish population structure and dynamics, age and growth, reproductive biology, and food web ecology on various temporal and spatial scales.

Seasonal variability in ichthyoplankton abundance and assemblage composition in the northern Gulf of Mexico off Alabama

Multiyear ichthyoplankton surveys used to monitor larval fish seasonality, abundance, and assemblage structure can provide early indicators of regional ecosystem changes. Numerous ichthyoplankton surveys have been conducted in the northern Gulf of Mexico, but few have had high levels of temporal resolution and sample replication. In this study, ichthyoplankton samples were collected monthly (October 2004–October 2006) at a single station off the coast of Alabama as part of a long-term biological survey. Four seasonal periods were identified from observed and historic water temperatures, including a relatively long (June–October) “summer” period (water temperature >26°C). Fish egg abundance, total larval abundance, and larval taxonomic diversity were significantly related to water temperature (but not salinity), with peaks in the spring, spring–summer, and summer periods, respectively. Larvae collected during the survey represented 58 different families, of which engraulids, sciaenids, carangids, and clupeids were the most prominent. The most abundant taxa collected were unidentified engraulids (50%), sand seatrout (Cynoscion arenarius, 7.5%), Atlantic bumper (Chloroscombrus chrysurus, 5.4%), Atlantic croaker (Micropogonias undulatus, 4.4%), Gulf menhaden (Brevoortia patronus, 3.8%), and unidentified gobiids (3.6%). Larval concentrations for dominant taxa were highly variable between years, but the timing of seasonal occurrence for these taxa was relatively consistent. Documented increases in sea surface temperature on the Alabama shelf may have various implications for larval fish dynamics, as indicated by the presence of tropical larval forms (e.g., fistularids, labrids, scarids, and acanthurids) in our ichthyoplankton collections and in recent juvenile surveys of Alabama and northern Gulf of Mexico seagrass habitats.

Habitat and bycatch effects on population parameters of inshore lizardfish (Synodus foetens) in the north central Gulf of Mexico

We examined the effect of habitat and shrimp trawl bycatch on the density, size, growth, and mortality of inshore lizardfish (Synodus foetens), a nonexploited species that is among the most widespread and abundant benthic fishes in the north central Gulf of Mexico. Results of quarterly trawl sampling conducted from spring 2004 through spring 2005 revealed that inshore lizardfish are most abundant on sand habitat, but larger fish are more common on shell rubble habitat. There was no significant difference in fish density between habitats exposed to shrimp trawling on the open shelf versus those habitats within a permitted artificial reef zone that served as a de facto no-trawl area; this finding indicates that either inshore lizardfish experienced minimal effects from trawling or, more likely, that fish moved between trawled and nontrawled habitats. Exploitation ratio (bycatch mortality/total morality) estimates derived from catch curve analysis ranged from 0.43 inside the artificial reef zone to 0.55 outside the reef zone, thus indicating that inshore lizardfish are subject to significant fishing mortality in the north central Gulf of Mexico despite the lack of a directed fishery for the species. We infer from this result that effects of shrimp trawl bycatch may be significant at the population level for nonexploited species and that a broader ecosystem-scale examination of bycatch effects is warranted.

A tributação sob uma ótica de justiça: o caso do Imposto sobre Transmissões Causa Mortis e Doações (ITCMD)

A ideia central da dissertação é a analise da tributação sob uma ótica de justiça. Teorias contemporâneas de justiça são apresentadas para compor o arcabouço teórico do trabalho. São apresentadas a teoria de justiça de John Rawls, que enfatiza o tema da redistribuição de rendas, a concepção de justiça de Nancy Fraser, que enquadra a categoria filosófica do reconhecimento como fundamental e sendo uma dimensão irredutível da justiça, assim como a visão de Jaques Derrida sobre a ideia de justiça. Princípios constitucionais tributários são introduzidos com o propósito de estabelecer esta relação entre a justiça abstratamente considerada e a análise concreta de instituição de um imposto. São analisadas possíveis influências das teorias apresentadas nos princípios constitucionais tributários, principalmente no princípio da capacidade contributiva. E será também analisado o Imposto sobre Transmissões Causa Mortis e Doações (ITCMD) sob a ótica de justiça conforme as teorias apresentadas. As conclusões apresentadas fortalecem a tese de que os atuais contornos e limites impostos à instituição do ITCMD no Brasil enfraquecem os princípios constitucionais relacionados a este imposto, quando estes são vistos à luz das teorias contemporâneas de justiça apresentadas.
