Estilo, comovimento e previsibilidade de retorno: uma análise do mercado brasileiro entre 2000-2011

Wahal e Yavuz (2009) divulgaram trabalho ampliando a literatura da teoria de finanças comportamentais, unindo os conceitos de momento, estilo e comovimento como ferramentas de previsibilidade de retorno em investimentos. Eles descobriram que ativos com maior comovimento apresentam retornos mais elevados que os de baixo comovimento. Buscamos replicar a sua metodologia ao mercado brasileiro de maneira aplicável a realidade de baixa liquidez e quantidade reduzida de ativos do nosso mercado de ações. Nossos resultados não apresentaram a mesma tendência do trabalho original, porém verificamos, ainda que de forma limitada, a possibilidade de explorar estratégias lucrativas usando este arcabouço.

Okupar, resistir, insistir : uma etnografia das práticas de ocupação urbana Fortaleza / Ceará

The objective of this dissertation is understand the relationships built between subjects who occupy buildings in a state of abandonment to revitalize them - called okupas, noting which individuals construct such meanings on the practice of occupation and how to organize the construction and maintenance of a collective life project. Having the Okupa Squat Torém, located in the neighborhood of Fatima in the southern city of Fortaleza-CE, as locus and observed through the ethnographic method, followed the social practices of urban segment. I invested in a data collection revealed that the custom of okupas and their domestic habits, inside and outside of okupa, emphasizing the interaction situations, like most appropriate occasions to observe the constant negotiation and refinement of his cunning to intervene in the city . Among the objectives of this research, the main thing is to observe which senses are assigned to the practice of the occupation by okupas. For this, reflecting from the specifics of this urban phenomenon and talking mostly with the tradition of research in the field of anthropology, I tried to address some issues regarding the practice of okupação and organization of the group, which the principles and movements that make these contacts with city etc. The appropriation made by the subjects on the urban space here means understanding them as a cultural expression of a number of collective values, resulting from experience and perception of okupas like themselves. The intention is to show how this practice intervention and collective action has appeared in contemporary times and how my ethnography can contribute to a dialogue on the practices of mobilization and update of the city, considering the Theory of Recognition Axel Honneth (2003) as an analytical category useful to describe the forms of reciprocity experienced by okupas

Repercussões sociais da violência contra crianças e adolescentes: deliqüência

This research is responsible for the investigation and problematization of the violence production process in children and teenagers through deviant behaviour, especially the drug s use and traffic, given that the deviant behaviour named juvenile criminality is something built and that can t be disassociated from the social and institutional relations that are ideological and violent, as well as the construction of, social and individual, positive identities can become important instruments for the process of democratization and the effective juvenile citizenship. In relation to the teorical referential, the work was developed from readings beyond the social science camp, without getting far from it, searching for support in other scientific camps and making your bases on Manuel Castells formulations about the power of the identity, and on Nancy Fraser and Axel Honneth in relation to the recognition struggle. In the empiric field, the discourses and graphic representations from twenty four children and teenagers that attend a social project were privileged, and compared to those shown at the documentary and the book Falcão Meninos do Tráfico produced by MV Bill, in relation to the social profile and life trajectory. From the study subjects' perspective, the data suggest that the children and the teenagers conceive violence as a natural thing, either as victims or persecutors. However, the research shows that, despite the subjects of the two studied groups reveled in your discourses the influence of the violent relations in their daily lives, the subjects got recognition during the process of identity construction by the groups with which they maintained the sense of belonging, either it being the family, the community or the school, they were positively influenced and established a positive representation of themselves and didn t show any deviant and violent tendency or behaviour. Therefore, we demonstrate the role of the school for an education for peace, as well as the participation of the family, the community and the stimulation of the juvenile protagonism as transforming practices, capable of awaking the citizenship and avoiding the construction of people that reproduce deviant and violent behaviour

A ética econômica das classes trabalhadoras: a gramática social do comportamento econômico da nova pequena burguesia comercial de Natal/RN

Rogram relying on sociological interface between Economic Sociology, Sociology of Moral Theory of Socialization and Social Stratification, this dissertation research makes use of theoretical contributions Luic Boltanski, Charles Taylor, Axel Honneth, Pierre Bourdieu and Bernard Lahire to problematize the generally about the physical and symbolic production and social reproduction of the type of "economic ethics" predominant in the new petite bourgeoisie Brazilian. In other words, the goal is to explain and analyze the objective conditions (economic needs and moral grammar) and intersubjective (modes of socialization and social networks) and update the social genesis and contextual transcontextual beliefs, biases, inclinations and cultural regularities observed the economic behavior of individual profiles for the fractions of the urban petty bourgeoisie and commercial upward Natal / RN. With regard to methodological strategies adopted in data collection will be conducted qualitative interviews (semistructured) and ethnographic notes. In turn, the analytical treatment of the collected empirical content is based on the approach dispositionalist (Pierre Bourdieu, Loïc Wacquant and Bernard Lahire) that emphasizes the study of the past embedded agents and the different contexts of incorporation / activation / inhibition of "provisions" individual cultural

Nas veredas por reconhecimento social: o papel da educação na desconstrução da inferioridade dos sujeitos do campo.

En la travesía por nuevos caminos en la investigación académica, se nos presenta el desafío de investigar alternativas que muestran un horizonte de posibilidades concretas de una educación pautada en la dinámica de organizaciones y movimientos que participan de la lucha por un proyecto de reconocimiento social y desconstrucción de la inferioridad de los sujetos del campo. El escenario de participación de la vida de los que integran la investigación como investigados e investigador es el Territorio Sertão do Apodi, localizado en el estado de Rio Grande do Norte, cuya elección empírica fue motivada por la fuerte presencia y participación de movimientos sociales en el campo. La propuesta es investigar posibilidades y desafíos de prácticas y acciones educativas tanto dentro como fuera de la escuela que buscan reconocer y dar visibilidad a los sujetos sociales del campo en el referido Territorio. Así, será objeto de nuestra investigación el espacio de tomada de decisiones y de organización de institucionalidad territorial a través de la actuación del Colegiado del Territorio del Sertão do Apodi y de las prácticas educativas resultantes de las demandas de las acciones territoriales, tanto escolares como no escolares. La literatura en la cual sedimentamos las bases teóricas fundamentales de esta investigación es la de Axel Honneth (2001; 2003), asociada al pensamiento de Boaventura Santos (2003; 2008a), Jesse Souza (2003, 2006) y Milton Santos (2006, 2007, 2009). Vale destacar, aún, la interlocución con la narrativa de Guimarães Rosa, a través de la obra Grande Sertão: Veredas, sobrepasando todo el conjunto del texto. Con esta intención, procuramos defender que una perspectiva de educación destinada a los sujetos del campo debe pautarse en la superación de la condición de invisibilidad social, a que estos están sometidos, por medio de una postura de reconocimiento social que se afirma en el ejercicio de la democracia participativa y en la reparación de desigualdades sociales. Para esto, son muchos los desafíos y las vulnerabilidades de este proceso; y desde ahí, abriremos caminos para lograr el reconocimiento del papel de la educación y el fortalecimiento de las identidades sociales, al situar al sujeto socialmente, permitiendo que se localice en un determinado grupo social, frente a los saberes construidos en la sociedad

Host specificity of sheep and cattle nematodes in São Paulo state, Brazil

The trial was carried out to investigate parasite host specificity and to analyse the dynamics of infection with nematodes parasitizing sheep and catt:le raised together or separately in São Paulo state, Brazil, and, also to clarify doubts about the systematics of species of the genus Haemonchus on the basis of cytological and morphological studies. Ten steers and 32 ewes were randomly assigned to three paddocks (P), as follows: P1, 5 steers; P2, 5 steers and 16 ewes; and P3, 16 ewes. The animals remained on these paddocks in continuous grazing throughout the trial (1-yr period). Faecal exams and larvae counting on pasture were performed fortnightly. Once a month two tracer lambs were placed in each paddock, while two tracer calves were also placed, but only in the eighth month of the trial. All these animals were slaughtered for worm identification and counting. At the end of the trial, one steer and one ewe from P2, which showed high faecal egg counts, were also slaughtered for the same purpose. Nematodes identified cytogenetically as H. placei presented spicule hooks longer than those identified as H. contortus. The following distribution of parasites in cattle and sheep was observed: Bunostomum phlebotomum, H. similis, Mammomonogamus laryngeus strongly adapted to cattle, H. placei and Cooperia punctata more adapted to cattle than to sheep, Trichostrongylus axel and C. spatulata apparently more adapted to cattle, T. colubriformis strongly adapted to sheep, H. contortus more adapted to sheep than to cattle and C. curticei apparently more adapted to sheep. Cross-infection was shown to occur involving some species, however, with time the animals apparently eliminate the species that are not well adapted to them. Therefore, grazing management systems using cattle and sheep appear to be promising for worm control in southeastern Brazil. (C) 1997 Elsevier B.V. B.V.

Comparative efficacy evaluation of moxidectin gel and ivermectin paste against internal parasites of equines in Brazil

A total of 24 male and female equines of mixed breed, 10-20 months of age and naturally infected with internal parasites was utilized in a controlled test to evaluate the efficacy of a moxidectin 2% gel formulation at the dosage of 0.4 mg moxidectin per kg of live weight and an ivermectin 1.87% commercial paste formulation at the dosage 0.2 mg ivermectin per kg applied orally Animals were allocated into three groups of eight horses each based on pre-treatment eggs per gram (EPG) counts and treatments were randomized among the groups. One group was kept as untreated controls. One animal in the moxidectin-treated group died before the end of the trial from a cause unrelated to treatment leaving a total of seven animals in this group. Fecal egg counts were performed three times post-treatment and the number of parasites remaining in each animal was determined. Statistical analyses using geometric means were performed at the 1% level of significance. Both moxidectin and ivermectin preparations reduced initial EPG from a mean of 1600 to 0 on Days 5, 7 and at the end of the trial on Day 14. Efficacy percentages of moxidectin and ivermectin against immature and adult nematodes were as follows: Trichostrongylus axel, Parascaris equorum, Strongylus edentatus, S. vulgaris, Triodontophorus spp. and Gyalocephalus capitatus, 100% for both products; Habronema muscae 99.5 and 99.6%, respectively, Strongyloides westeri, 100 and 99.2%, respectively; Oxyuris equi, 99.6 and 100%, respectively; small strongyles, 99.7% for both products. of the latter, the most numerous were: Cylicocyclus insigne, Cylicostephanus longibursatus and Cyathostomum catinatum. No Gasterophilus nasalis were found in horses from either treated group, while two of eight control horses had infections with this parasite. Moxidectin showed greater efficacy (84.9%) than ivermectin (67.8%) against Strongylus vulgaris larvae found in the mesenteric artery aneurisms, but the difference was not statistically significant. Total parasite counts for both treated groups were significantly lower (p<0.01) than in the non-treated group. No significant differences were noted between moxidectin and ivermectin. Efficacy against the 30 nematode species found in this study was very evident for both products. As expected, neither moxidectin nor ivermectin was effective in controlling the tapeworm Anoplocephala perfoliata. No adverse reactions were observed during the experimental period.

Predation on spawn and adults of Chaunus dorbignyi (Dumeril & Bibron, 1841) (Amphibia, Anura) by leeches (Hirudinea) in southern Brazil.

Two species of leeches (Hirudinea) are reported as frequently associated with amphibians in Rio Grande do Sul state, southern Brazil. We observed the predation of eggs of the bufonid Chaunus dorbignyi; remarkably, the remaining eggs of this clutch did not complete their embryologic development, probably due to a negative effect caused by the leeches. We report on additional observations of leeches feeding on other anuran species.
