Use of medicinal plants by black women: ethnography study in a low-income community

Objective To explore beliefs, values and practices related to the use of medicinal plants among low-income black families. Method The research method was ethnography and the participant observation process was done in a low-income community in the peripheral area of the City of São Paulo. Twenty black women were interviewed. Results Two cultural sub-themes, I do use medicines that I learned to make with my mother and with religious practitioners to care for diseases and Home medicines are to treat problems that are not serious, and the cultural theme I do use home medicines to treat simple diseases because I always have them at my disposal, they are free and I don’t need a medical prescription represent beliefs, values, and practices related to the use of medicinal plants among low-income black families. Conclusion The development of such practices, which can hide ethnic and social vulnerability, reveals the resilience of low-income black women in the process of confronting problems during the health-illness process.

Gifted: the monolingualism of corporate social responsibility

Acts of Corporate Social Responsibility are more often than not portrayed as success-story narratives. A quasi-ethnographic study in Senegal shatters the underlying assumptions of these accounts. First a computer donation from a Northern country is described with all the usual incidents and related vocabulary. Later, during a visit to a Senegalese rubbish dump, the story starts to falter, as countless questions arise about what is actually going on there, and how we can know and represent it (both as a portrayal and as a voice). A tipping point in an interview serves to reveal the ambiguities of the position adopted and the difficulties of expressing oneself in a different language. The CSR language is described as a kind of monolingualism, which employs a particular vocabulary and grammar for what is said or thought. This is the monolingualism of the other. Some of the implications of this monolingualism are examined, and this leads to the conclusion that there is a need to take measures with regard to the CSR language and that more than one language is needed to speak about CSR.

Methodological aspects of the 1993 Pelotas (Brazil) birth cohort study

This paper describes the main methodological aspects of a cohort study, with emphasis on its recent phases, which may be relevant to investigators planning to carry out similar studies. In 1993, a population based study was launched in Pelotas, Southern Brazil. All 5,249 newborns delivered in the city's hospitals were enrolled, and sub-samples were visited at the ages of one, three and six months and of one and four years. In 2004-5 it was possible to trace 87.5% of the cohort at the age of 10-12 years. Sub-studies are addressing issues related to oral health, psychological development and mental health, body composition, and ethnography. Birth cohort studies are essential for investigating the early determinants of adult disease and nutritional status, yet few such studies are available from low and middle-income countries where these determinants may differ from those documented in more developed settings.

Organization of healthcare and assistance to the elderly indigenous population: synergies and particularities of the professional context

This study aimed to describe the effects of the organization of primary healthcare on the assistance provided to the elderly Kaingang population, according to the perception of health professionals that work in this area. It is a qualitative and descriptive study, supported by ethnography methodological references, and was conducted with ten healthcare professionals that work in Faxinal, an indigenous territory in the state of Paraná, in Brazil. Data was collected from November 2010 to February 2012 through participant observation and interviews. The results revealed that health professionals strive to meet the health needs of the elderly Kaingang people; however, there are negative effects that hinder the professional care, especially limited human resources, lack of training and material resources, heavy workload and high turnover rates. This study highlights the need to improve work conditions in order to provide better healthcare.

Cultural singularities: indigenous elderly access to Public Health Service

OBJECTIVEDescribing how Kaingang seniors and their primary caregivers experience access to public health services.METHODA qualitative study guided by ethnography, conducted with 28 elderly and 19 caregivers. Data were collected between November 2010 and February 2013 through interviews and participative observation analyzed by ethnography.RESULTSThe study revealed the benefits and difficulties of the elderly access to health services, the facility to obtain health care resources such as appointments, medications and routine procedures, and the difficulties such as special assistance service problems and delays in the dispatching process between reference services.CONCLUSIONThe importance of knowing and understanding the cultural specificities of the group in order to offer greater opportunities for the elderly access to health services was reinforced.

Effects of web-based electrocardiography simulation on strategies and learning styles

OBJECTIVETo identify the association between the use of web simulation electrocardiography and the learning approaches, strategies and styles of nursing degree students.METHODA descriptive and correlational design with a one-group pretest-posttest measurement was used. The study sample included 246 students in a Basic and Advanced Cardiac Life Support nursing class of nursing degree.RESULTSNo significant differences between genders were found in any dimension of learning styles and approaches to learning. After the introduction of web simulation electrocardiography, significant differences were found in some item scores of learning styles: theorist (p < 0.040), pragmatic (p < 0.010) and approaches to learning.CONCLUSIONThe use of a web electrocardiogram (ECG) simulation is associated with the development of active and reflexive learning styles, improving motivation and a deep approach in nursing students.

Knowledge hierarchy and professional knowledge

The aim of this article is to substantiate, in the sociological point of view, the distinction between the social and cognitive processes that produce knowledge in knowledge abstract systems - KAS - to generate cultural inequality and the micro processes of knowledge usage, which build local and cultural knowledge from common sense. It is circumscribed to this aim a problematization of knowledge usage developed by middle class salaried professional groups, rich in cultural capital but without equivalent symbolical capital, in a capitalist society at risk. In order to achieve this goal, the classical contributions of Pierre Bourdieu, Boaventura Sousa Santos, Donald Schön and Basil Bernstein (among others) are taken as a basis regarding the limitation of critical and reflexive thinking and the virtues of professional knowledge to support an epistemology of professional practice.

A formação do Químico

Training of highly qualified personnel is the most transversal axis among those identified in the document "Mobilizing Axes in Chemistry", published by SBQ, in 2002, which demands to deep the discussions, initiated in the symposium "The Chemist's Education", whose main objective was to discuss the repercussions of that training in the teaching and in the industrial section. After the publication of an initial paper, a couple of meetings and workshops held in Rio de Janeiro, in December 2003, involving the national chemist community, discussed the "The role of the graduate degrees in the Chemist's Education" and "The Chemist's Education", and confirmed the need to invest in the formation of qualified human resources in profusion and in all levels. Actions to be taken were delineated. Presently, the graduate programs in Chemistry are showing expressive results. However, although these professionals are mostly absorbed by the academy (the absorption of the industry is less significant), only a few programs give special attention to the didactical and pedagogical training. The regional decentralization is actually a tendency in most programs, but the interaction academy-economic activities is still a challenge. It is necessary to establish with the industrial section, the highly qualified professional's profile in Chemistry that the industry can absorb. The undergraduation is growing in number and quality, however still excessively concentrated in the Southeast area. The national "Curricula Guidelines" for Chemistry Courses, through its flexible approach, propitiate the integral, interdisciplinary (non compartmentalized) and critical-reflexive training of the professionals as citizens and as entrepreneurs. However, deficiencies are still recognized. The evaluation system of undergraduate courses has been able to identify the most fragile modalities of courses and other indicators. It was also verified that Brazilian chemistry industry absorbs minimally the highly qualified professionals, which is attributed to the fact that the Federal Council of Chemistry is vertically organized and does not recognize the graduate degrees as professional qualification. In the conclusion, it stands out, among other aspects, the importance of the effective implantation of the national curricula guidelines, bringing out courses whose didactical and pedagogical projects may offer a solid formation in Chemistry, but comprehensive and general enough to enable the Chemistry professionals to develop varied skills.

A graduação em química: um novo químico para uma nova era

The discussions sponsored by the Brazilian Chemical Society, over the past five years, intending to produce a chemistry agenda with perspectives and needs for the next decade for the country, have involved the national chemistry community and several related sectors of Brazilian society. Chemistry education has been the theme throughout these discussions. It is known that the low level of basic and secondary education and the recent increase in high school courses and institutions adversely affect the quality of undergraduate teaching. The recent national "Curriculum Guidelines" for Chemistry Courses, through their flexible approach, encourage the integral, interdisciplinary (non compartmentalized) and critical-reflexive training of professionals as citizens and as entrepreneurs. However, deficiencies are still recognized. The system of undergraduate course evaluation has identified the most fragile modalities of the courses and other indicators. Also, it has been verified that the Brazilian chemistry industry absorbs only minimally the highly qualified professionals, which is attributed to the fact that the Federal Council of Chemistry is vertically organized and does not recognize the graduate degrees as professional qualifications. In conclusion, the importance of the effective implantation of the national curriculum guidelines is apparent, among other aspects, highlighting courses whose didactical and pedagogical projects may offer a solid formation in Chemistry. However, at the same time the guidelines are comprehensive and general enough to enable the chemistry professionals to develop varied skills.

Implantação das diretrizes curriculares nacionais para formação de professores de química em uma instituição federal de ensino superior: desafios e perspectivas

The Curricular Proposals for Chemistry Teaching Courses aim at producing a reflexive-researcher teacher, who will be able to deal with cross-disciplinary subjects. The challenge faced by the majority of the federal universities, in implementing these guidelines, is to attain these objectives inside their departmental structure. We present here the formulation of the Chemistry Teaching Course Pedagogic Project from Federal University of Pelotas concerning on the CNE/CP 1/2002 and 2/2002 Resolutions. We discuss the impact of these Proposals, the difficulties faced and the new perspectives of organization inside of these institutions, which resulted in new spaces with cross-disciplinary and cross-departmental orientation.

Monoamines in the pedal plexus of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)

In molluscs, the number of peripheral neurons far exceeds those found in the central nervous system. Although previous studies on the morphology of the peripheral nervous system exist, details of its organization remain unknown. Moreover, the foot of the terrestrial species has been studied less than that of the aquatic species. As this knowledge is essential for our experimental model, the pulmonate gastropod Megalobulimus oblongus, the aim of the present study was to investigate monoamines in the pedal plexus of this snail using two procedures: glyoxylic acid histofluorescence to identify monoaminergic structures, and the unlabeled antibody peroxidase anti-peroxidase method using antiserum to detect the serotonergic component of the plexus. Adult land snails weighing 48-80 g, obtained from the counties of Barra do Ribeiro and Charqueadas (RS, Brazil), were utilized. Monoaminergic fibers were detected throughout the pedal musculature. Blue fluorescence (catecholamines, probably dopamine) was observed in nerve branches, pedal and subepithelial plexuses, and in the pedal muscle cells. Yellow fluorescence (serotonin) was only observed in thick nerves and in muscle cells. However, when immunohistochemical methods were used, serotonergic fibers were detected in the pedal nerve branches, the pedal and subepithelial plexuses, the basal and lateral zones of the ventral integument epithelial cells, in the pedal ganglion neurons and beneath the ventral epithelium. These findings suggest catecholaminergic and serotonergic involvement in locomotion and modulation of both the pedal ganglion interneurons and sensory information. Knowledge of monoaminergic distribution in this snail´s foot is important for understanding the pharmacological control of reflexive responses and locomotive behavior.
