Archaeofacies Analysis: Using Depositional Attributes to Identify Anthropic Processes of Deposition in a Monumental Shell Mound of Santa Catarina State, Southern Brazil

In the coast of Santa Catarina State (southern Brazil), a large population of monumental shell mounds characterizes a highly dynamic coastal setting. In this paper, sedimentary facies analysis was adapted for description, sampling, and interpretation of shell mound complex and repetitive archaeostratigraphic successions. Archaeofacies identification in the field, according to depositional attributes, is tested by contrasting field description with multi-element chemical analyses, total carbon and nitrogen determinations, and micromorphological descriptions. Two vertical sequences at the black deposit of Jabuticabeira II shell mound were studied and preliminary results showed that: (1) depositional attributes are a reliable base for archaeofacies identification in the field, (2) the formation process of this site involved a sequence of anthropic depositional processes, where burned refuse was redeposited over the shell mound following a ritual construction pattern, and (3) the black deposit includes a double palimpsest that refers to provenance and meaning of mound construction material.

Patterns and processes of diversification in a widespread and ecologically diverse avian group, the buteonine hawks (Aves, Accipitridae)

Buteonine hawks represent one of the most diverse groups in the Accipitridae, with 58 species distributed in a variety of habitats on almost all continents. Variations in migratory behavior, remarkable dispersal capability, and unusual diversity in Central and South America make buteonine hawks an excellent model for studies in avian evolution. To evaluate the history of their global radiation, we used an integrative approach that coupled estimation of the phylogeny using a large sequence database (based on 6411 bp of mitochondrial markers and one nuclear intron from 54 species), divergence time estimates, and ancestral state reconstructions. Our findings suggest that Neotropical buteonines resulted from a long evolutionary process that began in the Miocene and extended to the Pleistocene. Colonization of the Nearctic, and eventually the Old World, occurred from South America, promoted by the evolution of seasonal movements and development of land bridges. Migratory behavior evolved several times and may have contributed not only to colonization of the Holarctic, but also derivation of insular species. In the Neotropics, diversification of the buteonines included four disjunction events across the Andes. Adaptation of monophyletic taxa to wet environments occurred more than once, and some relationships indicate an evolutionary connection among mangroves, coastal and varzea environments. On the other hand, groups occupying the same biome, forest, or open vegetation habitats are not monophyletic. Refuges or sea-level changes or a combination of both was responsible for recent speciation in Amazonian taxa. In view of the lack of concordance between phylogeny and classification, we propose numerous taxonomic changes. (C) 2009 Elsevier Inc. All rights reserved.

Homophobic discourse in blogs: Weaving of violence and network

This article aims at analyzing the effects of meaning installed in the discursive space of a blog, especially a formulation of discriminatory nature which was posted in November, 2011 and considerably discussed in other discursive spaces on the Internet. By means of French Discourse Analysis, we sought to track the memory networks and the ideological effects that are at play in the discourse on homosexuals posted by browsers-subjects and how they update the meanings already there in order to install effects of prejudice and hatred. Our interest is also to catch the meanings of violence inscribed in the electronic network and analyze the functioning of the language in motion in this space bordered by the imaginary in which it is possible to say anything. Hence, by means of the analyses performed in this study, we observed these effects of the subject's full freedom when he/she subscribes to the electronic network without fear of any punishment of any order. The discourses of intolerance and hatred posted on the blog by the subject give voice to a discursive confrontation observed by marks of agreement or indignation, supported by the discursive memory. Thus, we observed the interruption of regularities that break up with a supposed linearity in the discourse, putting the contradiction and the heterogeneous nature of the sayings on the net in motion.

Analysis of phase transition and dehydration processes of nevirapine

Solid-state characterization of crystalline drugs is an important pre-formulation step for the development and design of solid dosage forms, such as pellets and tablets. In this study, phase transition and dehydration processes of nevirapine have been studied by differential scanning calorimetry and thermogravimetry differential thermal analysis to overcome the problems of drug formulation, namely poor solubility and poor content uniformity. Phase solubility studies elucidated the mechanism of enhanced nevirapine solubility.

Post-conventional Political Cultures via Processes of Direct Democracy: Theoretical Considerations Based on Jurgen Habermas and Lawrence Kohlberg

In this article, it is proposed to differentiate political cultures in two dimensions. First, inspired by Habermas' distinction of the contents of discourse, a distinction is suggested between moral, ethical-political and pragmatic elements of political culture as well as of an element of culture of balancing interests. Second, inspired by Kohlberg's stage models for the development of the individual moral consciousness and for moral culture, a distinction is similarly suggested between two pre-conventional, two conventional and two post-conventional collective stages of political culture. It can be shown that from a normative point of view, only deliberations made in a post-conventional political culture can produce reasonable or at least fair results. Conceptual considerations indicate processes of direct democracy as the method for promoting post-conventional political cultures. The more liberty that the citizens have to formulate and trigger processes of direct democracy, the more one can expect from them to generate post-conventional political cultures.

Characteristics of violence against children in a Brazilian Capital

The purpose of this exploratory, descriptive and retrospective study with a quantitative approach was to characterize violence against children in Curitiba. Reports of 2004 through 2008 about compulsory denouncements of violence cases were analyzed. The results showed an increase in violence, with home violence as the most frequent type and five to nine-year-olds as the most affected group, and negligence and physical violence as the most denounced forms of violence. Almost 81% of the sexual violence is performed against girls and the father is the main aggressor, showing inequality in gender relations and between generations. The importance of notification as a visibility instrument is highlighted. Other confrontation measures are necessary though, such as the promotion of equitable relationships of gender and generation, and cross-sectional policies that involve the social segments in a praxis that transforms reality.

Construction and validation of an instrument that breaks the silence: the impact of domestic and/or sexual violence on women's health, as shown during climacterium

Objective: The aim of this study was to construct and to validate a measure of the consequences of domestic violence on women's health during climacterium. Methods: A questionnaire was administered at the Outpatient Climacterium Clinic to 124 women aged 40 to 65 years who were the victims of domestic and/or sexual violence (experimental group). They were divided into three groups: (1) those who were victims of violence exclusively during childhood/adolescence, (2) those who were victims of violence exclusively during adulthood, and (3) those who were victims of violence throughout their lives. The instrument included 34 items evaluating the beginning, frequency, and type of violence; the search for health assistance and reporting of the violence; the violence and the number of comorbidities; and violence and the Kupperman Menopausal Index. We also included a control group composed of perimenopausal and postmenopausal women who did not experience any violence (n = 120). Results: The instrument presented a Cronbach alpha = 0.82, good reliability among the examiners (+0.80), and a good possibility of reproducibility. The mean age of menopause was 45.4 years, and the mean age in the control group was 48.1 years. Group 1 showed a mean of 5.1 comorbidities, Group 2 had 4.6, and Group 3 had 4.4. Sexual violence (43.5%) and other types of violence both presented average comorbidities (4.60) but represented a significant impairment in the victim's sexual life. There were significant associations in group 3 and a high Kupperman Menopausal Index score. In the experimental group, 80.6% did not seek health services for the violence they experienced. Conclusions: The questionnaire presented good internal consistency and a validated construction. It can be easily reproduced and is indicated to evaluate the consequences of domestic and/or sexual violence on women's health during climacterium.
