PROFILE OF CAREGIVERS OF ELDERLY PEOPLE WITH ALZHEIMER DISEASE ASSOCIATED TO RESILIENCE

This exploratory and descriptive study described sociodemographic and health variables of caregivers of elderly people with Alzheimer's disease, associating care provided with resilience. Participants were 101 caregivers over 18 years old who accompanied older adults in a Primary Care Unit of a Brazilian public hospital in 2009. Questionnaires regarding the profile, the Beck Depression Inventory, and the Resilience Scale were used. Descriptive statistical analysis was performed. Most caregivers were female, without depression, aided by other people in providing care, and had a high degree of resilience. The variables degree of kinship, medical treatment, the use of medication, tiredness, prostration, discouragement, and caregivers' mental health had significant association with resilience. Physical health was significantly associated to experience in care, with 82 elderly people presenting acute cognitive damage. Older adults in the family context can benefit from a more resilient caregiver.

Este texto é parte das reflexões teóricas do nosso Pós-doutorado realizado junto ao Laboratório de Antropologia Visual da Universidade Aberta de Portugal que abordou aspectos interculturais do estudo fotoetnográfico da publicidade e do consumo alimentar no Brasil e em Portugal. Aqui serão ressaltados os aspectos referentes às contribuições da semiótica para o estudo das comunicações publicitárias de alimentos. A proposta é entender os modelos de análise semiótica da publicidade como um meio de operacionalização da descrição densa, na perspectiva etnográfica, a partir da interface interdisciplinar com a produção de sentido das imagens publicitárias, no campo da alimentação, apresentado a análise de um anúncio do azeite Gallo como exemplo.

Consanguineous unions and the burden of disability: A population-based study in communities of Northeastern Brazil

Objectives: The aim of this study was to identify communities at high risk of transmitting recessive genetic disorders by measuring levels of endogamy and offspring's rate of disabilities. Methods: In a house-to-house population based-survey in the state of Paraiba, 20,462 couples were interviewed regarding kinship relation, number of siblings and offspring affected by mental or physical disabilities. Results: The rate of consanguineous unions in the communities ranged from 6.0% to 41.14%, showing an average value of 20.19% +/- 9.13%. The overall average inbreeding coefficient (F) was 0.00602 +/- 0.00253, ranging from 0.00134 to 0.01182. Communities situated on the backlands had an increased average value of F compared to those closer to the seashore (P = 0.024). The average rate of disabled offspring varied from 2.96% +/- 0.68% for unrelated unions to 10.44% +/- 16.86% for related couples at the level of double first cousins or uncleniece. The Spearman correlation coefficient between the overall rate of disabled offspring from all couples together and F was 0.510 (P < 0.01). Conclusion: Inbreeding increases the risk of disability which is unevenly distributed, varying considerably even in neighboring communities with similar Human Development Index and population density. Higher inbreeding communities are mostly located on the more economically underdeveloped backlands than on the coastal region. The identification of communities at high risk for genetic disorders could serve as basis for the establishment of Community Genetics programs. Am. J. Hum. Biol., 2012.

Kinematics and Energetics of Nut-Cracking in Wild Capuchin Monkeys (Cebus libidinosus) in Piaui, Brazil

Wild bearded capuchins (Cebus libidinosus, quadrupedal, medium-sized monkeys) crack nuts using large stones. We examined the kinematics and energetics of the nut-cracking action of two adult males and two adult females. From a bipedal stance, the monkeys raised a heavy hammer stone (1.46 and 1.32 kg, from 33 to 77% of their body weight) to an average height of 0.33 m, 60% of body length. Then, they rapidly lowered the stone by flexing the lower extremities and the trunk until the stone contacted the nut. A hit consisting of an upward phase and a downward phase averaged 0.74 s in duration. The upward phase lasted 69% of hit duration. All subjects added discernable energy to the stone in the downward phase. The monkeys exhibited individualized kinematic strategies, similar to those of human weight lifters. Capuchins illustrate that human-like bipedal stance and large body size are unnecessary to break tough objects from a bipedal position. The phenomenon of bipedal nut-cracking by capuchins provides a new comparative reference point for discussions of percussive tool use and bipedality in primates.

Amerindian anthropology and cultural psychology: Crossing boundaries and meeting otherness` worlds

Addressing integrative possibilities between psychology and anthropology, this paper aims to design conceptual linkages between semiotic-cultural constructivist psychology and the anthropological theory of Amerindian perspectivism. From the psychological view, it is the interdependence between the structural and processual dimensions of the personal culture that makes parallels with Amerindian perspectivism fruitful. This anthropological frame proposes an experiment with native conceptions, which I argue similar to what Baldwin (1906) called sembling. Hence, it can be considered an active imitation of otherness` viewpoint in order to approach indigenous worlds. It is supposed that this procedure leads to the emergence of new symbolic elements configuring the cultural action field of each agency in interaction. It is proposed that ""making-believe`` the Amerindian is convergent with the dialogic-hermeneutic approach of semiotic-cultural constructivism. As a result of the present integrative effort, is designed a meta-model that multiplies the genetic process of concrete symbolic objects.

Costs and benefits of freezing behaviour in the harvestman Eumesosoma roeweri (Arachnida, Opiliones)

Animals present an enormous variety of behavioural defensive mechanisms, which increase their survival, but often at a cost. Several animal taxa reduce their chances of being detected and/or recognized as prey items by freezing (remaining completely motionless) in the presence of a predator. We studied costs and benefits of freezing in immature Eumesosoma roeweri (Opiliones, Sclerosomatidae). Preliminary observations showed that these individuals often freeze in the presence of the syntopic predatory spider Schizocosa ocreata (Araneae, Lycosidae). We verified that harvestmen paired with predators spent more time freezing than when alone or when paired with a conspecific. Then. we determined that predator chemical cues alone did not elicit freezing behaviour. Next, we examined predator behaviour towards moving/non-moving prey and found that spiders attacked moving prey significantly more, suggesting an advantage of freezing in the presence of a predator. Finally, as measure of the foraging costs of freezing, we found that individuals paired with a predator for 2 h gained significantly less weight than individuals paired with a conspecific or left alone. Taken together, our results suggest that freezing may protect E. roeweri harvestmen from predatory attacks by wolf spiders, but at the cost of reduced food and/or water intake. (C) 2009 Elsevier B.V.

Characterization of Opsin Gene Alleles Affecting Color Vision in a Wild Population of Titi Monkeys (Callicebus brunneus)

The color vision of most platyrrhine primates is determined by alleles at the polymorphic X-linked locus coding for the opsin responsible for the middle- to long-wavelength (M/L) cone photopigment. Females who are heterozygous at the locus have trichromatic vision, whereas homozygous females and all males are dichromatic. This study characterized the opsin alleles in a wild population of the socially monogamous platyrrhine monkey Callicebus brunneus (the brown titi monkey), a primate that an earlier study suggests may possess an unusual number of alleles at this locus and thus may be a subject of special interest in the study of primate color vision. Direct sequencing of regions of the M/L opsin gene using feces-, blood-, and saliva-derived DNA obtained from 14 individuals yielded evidence for the presence of three functionally distinct alleles, corresponding to the most common M/L photopigment variants inferred from a physiological study of cone spectral sensitivity in captive Callicebus.

Ceramic technology of the Asurini do Xingu, Brazil: An ethnoarchaeological study of artifact variability

This article presents some of the results of ethnoarchaeological research on ceramic technology I have conducted among the Asurini do Xingu, an Amazonian indigenous population inhabiting a village in the margins of the Xingu River, Para, Brazil. Based on collected data, presented throughout the article, I discuss the reasons behind the formal, quantitative, spatial and relational variability of the Asurini ceramic vessels. This work will demonstrate that these distinct dimensions of variability are related to the potters` technological choices during the vessels` production process, the ceramic teaching-learning structure, and the type, frequency, method and context of use of the same vessels. I try to make clear the different practical and symbolic aspects that may influence the production, use, reuse, storage and discard processes of the vessels. Furthermore, I compare the Asurini context with other ethnographic contexts and try to distinguish regularities that may serve as interpretative references to the study of archaeological ceramic assemblages.

First Micromorphological Studies Of Brazilian Sambaquis, Jabuticabeira II Site, Santa Catarina State

First Micromorphological Studies of Brazilian Sambaquis, Jabuticabeira II Site, Santa Catarina State. In this note, preliminary results from the micromorphological study of the fish mound that covers the Jabuticabeira II sambaqui site, developed within the interdisciplinary research project Sambaquis e paisagem, are presented. Microstratigraphic analyses enabled the identification of anthropic pre-depositional processes that participated in the formation of this large structure, related to the burning and transport of mineral and organic material (terrigenous sand and charcoal) and inorganic residues of biological origin (bones, phytoliths, diatoms and siliceous aggregates). The effects of post-depositional alterations over these particles can be observed through dissolution traces in bone and the formation of a fine mineral material of phosphatic composition. The articulation of the evidence confirms the complex combination of activities and alteration processes involved in the formation of sambaqui sites, which transcends traditional functional dichotomies.

THE HOUSE OF JOANA DARK: DRAMA AND PRODUCTION

While discussing images of Our Lady and of the mothers and women of the Garden of Flowers (or "Devils' Hole"), a peripheral district of a city in the interior of Sao Paulo state, this paper intends to explore the specificity of dramatic aesthetics. Rather than depend upon the aesthetics of social drama, as discussed in the works of Victor Turner, the present paper deals with a concept of montage that is inspired by the cinema of Sergei Eisenstein in order to illuminate a selection of field notes... and, along with Eisenstein, Julia Kristeva, Walter Benjamin, Michael Taussig and Antonin Artaud. Wit regards to those readers interested in hearing what these women may have to say, caution is suggested, for the words of these women may ring in our ears as the sounds of musket shots

The Effects of Processing Non-Timber Forest Products and Trade Partnerships on People's Well-Being and Forest Conservation in Amazonian Societies

This study evaluated whether processing non-timber forest products (NTFPs) and establishing trade partnerships between forest communities and companies enhance the outcomes of NTFP commercialization. In particular, we evaluated whether product processing, partnerships, or their combination was associated with a number of outcomes related to the well-being of forest inhabitants and forest conservation. We based our analyses on ethnographic and quantitative data (i.e., survey and systematic observations) gathered at seven communities from five societies of the Brazilian and Bolivian Amazon. Our results indicated that product processing and partnerships do not represent a silver bullet able to improve the results of NTFP commercialization in terms of well-being and conservation indicators. Compared with cases without interventions, households adopting partnerships but not product processing were most often associated with improved economic proxies of well-being (total income, NTFP income, food consumption and gender equality in income). In comparison, the combination of product processing and partnerships was associated with similar outcomes. Unexpectedly, product processing alone was associated with negative outcomes in the economic indicators of well-being. All of the investigated strategies were associated with less time spent in social and cultural activities. With respect to forest conservation, the strategies that included a partnership with or without processing produced similar results: while household deforestation tended to decrease, the hunting impact increased. Processing alone was also associated with higher levels of hunting, though it did not reduce deforestation. Our results indicate that establishing partnerships may enhance the outcomes of NTFP trade in terms of the financial outcomes of local communities, but practitioners need to use caution when adopting the processing strategy and they need to evaluate potential negative results for indicators of social and cultural activities. With respect to conservation, the three strategies are promising for reducing deforestation, but more pervasive impacts, such as hunting, might increase.

Impacts of Trade in Non-timber Forest Products on Cooperation among Caboclo Households of the Brazilian Amazon

Trade in non-timber forest products (NTFPs) has been touted as promoting forest conservation and enhancing the well-being of local residents through increased cash income, which is considered a positive outcome. However, research on cooperation has demonstrated that increased market access and income may strengthen or weaken cooperation. Because cooperation is essential for community resilience in small-scale societies, negative effects on people's well-being can be expected if increased NTFP trade reduces cooperation. To evaluate whether NTFP trade affected cooperation, we used household data (survey and systematic observations) to compare the frequency of cooperation in two communities of Brazilian Amazon Caboclos, one of which engaged in NTFP trade, while the other did not. Cooperation was less frequent in the community trading NTFPs, but neither household cash income nor household participation in NTFP exploitation was associated with cooperative behavior. Decreased frequency most likely derived from indirect effects of NTFP trade, such as less time to fish or socialize, or other outcomes observable only at the community level, such as income inequality, the influx of new residents and consequent population growth. Our results indicate that conservation and development projects based on NTFP trade may negatively impact social and economic well-being of local communities.

Tests of one Brazilian facial reconstruction method using three soft tissue depth sets and familiar assessors

Facial reconstruction is a method that seeks to recreate a person's facial appearance from his/her skull. This technique can be the last resource used in a forensic investigation, when identification techniques such as DNA analysis, dental records, fingerprints and radiographic comparison cannot be used to identify a body or skeletal remains. To perform facial reconstruction, the data of facial soft tissue thickness are necessary. Scientific literature has described differences in the thickness of facial soft tissue between ethnic groups. There are different databases of soft tissue thickness published in the scientific literature. There are no literature records of facial reconstruction works carried out with data of soft tissues obtained from samples of Brazilian subjects. There are also no reports of digital forensic facial reconstruction performed in Brazil. There are two databases of soft tissue thickness published for the Brazilian population: one obtained from measurements performed in fresh cadavers (fresh cadavers' pattern), and another from measurements using magnetic resonance imaging (Magnetic Resonance pattern). This study aims to perform three different characterized digital forensic facial reconstructions (with hair, eyelashes and eyebrows) of a Brazilian subject (based on an international pattern and two Brazilian patterns for soft facial tissue thickness), and evaluate the digital forensic facial reconstructions comparing them to photos of the individual and other nine subjects. The DICOM data of the Computed Tomography (CT) donated by a volunteer were converted into stereolitography (STL) files and used for the creation of the digital facial reconstructions. Once the three reconstructions were performed, they were compared to photographs of the subject who had the face reconstructed and nine other subjects. Thirty examiners participated in this recognition process. The target subject was recognized by 26.67% of the examiners in the reconstruction performed with the Brazilian Magnetic Resonance Pattern, 23.33% in the reconstruction performed with the Brazilian Fresh Cadavers Pattern and 20.00% in the reconstruction performed with the International Pattern, in which the target-subject was the most recognized subject in the first two patterns. The rate of correct recognitions of the target subject indicate that the digital forensic facial reconstruction, conducted with parameters used in this study, may be a useful tool.

Macroscopic and microbiological alterations of bird and small mammal bones buried in a Cerrado biome (south western Brazil)

In this paper, we present the results of an experimental approach developed to study the macroscopic and microbiological alteration of bird and small mammal bones buried under a Cerrado biome. The first experiment evaluated the macroscopic alteration of cooked and fresh carcasses buried through the dry and rainy seasons. The second experiment analyzed the mycobiota associated to the decomposition of a complete bird that remained buried for almost a year. Results show that in tropical forest environments: 1) bone structure and pre-taphonomic factors determine its differential alteration by biochemical processes; 2) fungal populations associated to the decomposition of animal remains depend on soil chemistry and ecological dynamics; 3) even in a corrosive environment, bird bones are more capable of surviving to several mycological decomposition steps.
