ABSTRACT

Este artículo tiene por objetivo mostrar la utilidad didáctica de una herramienta de investiga-ción cualitativa, como es el relato autoetnográfico, en el proceso de formación y autoconoci-miento de futuros profesionales del Trabajo social. Para ello, se tomará como marco una expe-riencia docente que utiliza la autoetnografía como estrategia formativa en el aula. El análisis de dicha experiencia y de los propios relatos de los alumnos/as permitirá descubrir su valor como estrategia de autoconocimiento, así como la emergencia de algunos aprendizajes espe-cialmente relevantes surgidos del encuentro entre la reflexión personal y el aprendizaje aca-démico, como son: el saber que aporta la experiencia vivida como usuario/a del sistema de atención en salud; el que se genera a través del tránsito por los dispositivos sanitarios y sus formas de organización actual; el surgido del encuentro con la propia vulnerabilidad; y la expe-riencia corporeizada de ciertos fenómenos asociados a los procesos de sa-lud/enfermedad/atención. (AU)


The aim of this paper is to demonstrate the educational use of a qualitative research tool like autoethnographic stories in the process of training and building of self-awareness of future social work professionals. Our framework of analysis will be a teaching experiment of the au-thor in which autoethnography was used as training strategy in the classroom. Analyzing the students’ stories will allow us to discover the value of autoethnography as a strategy to raise self-awareness. Also, we show how some especially relevant learning comes out of the encoun-ter of personal reflection and academic training, namely: the knowledge stemmingfrom one’s own experience as a user of the health care system; the one from a person’s passing through healthcare institutions and the way they are presently organized; the one that emerging from the coming face to face with one’s own vulnerability; and the corporealized experience of cer-tain phenomena associated with health/disease/care processes.

ABSTRACT

The human evolutionary sciences place high value on quantitative data from traditional small-scale societies that are rapidly modernizing. These data often stem from the sustained ethnographic work of anthropologists who are today nearing the end of their careers. Yet many quantitative ethnographic data are preserved only in summary formats that do not reflect the rich and variable ethnographic reality often described in unpublished field notes, nor the deep knowledge of their collectors. In raw disaggregated formats, such data have tremendous scientific value when used in conjunction with modern statistical techniques and as part of comparative analyses. Through a personal example of longitudinal research with Batek hunter-gatherers that involved collaboration across generations of researchers, we argue that quantifiable ethnographic records, just like material artifacts, deserve high-priority preservation efforts. We discuss the benefits, challenges, and possible avenues forward for digitizing, preserving, and archiving ethnographic data before it is too late.

ABSTRACT

RESUMEN Objetivo Identificar las acciones concretas y significativas que establecen las familias de personas con discapacidad víctimas de desplazamiento forzado para la (re)construcción de sus redes sociales en la localidad de Ciudad Bolívar de la ciudad de Bogotá. Metodología Estudio cualitativo con enfoque etnográfico. Se realizaron 5 encuentros para el diálogo sentido con un grupo focal de 28 personas víctimas de desplazamiento, entre personas con discapacidad y cuidadores y otros miembros del núcleo familiar, que participan en procesos de inclusión social, habitantes de la localidad de Ciudad Bolívar. La información se registró en diarios de campo, fotografías, videos y material construido por los participantes. Resultados Los resultados muestran que los procesos que permiten la reconstrucción de tejido social están preponderantemente enmarcados en la satisfacción de necesidades concretas como el trabajo, la vivienda, la educación y la alimentación, dejando invisibles los aspectos significativos de la vida de los participantes. Conclusiones La percepción que existe sobre la discapacidad, aunada a la situación de desplazamiento, dibuja un panorama de mayor exclusión social frente a las relaciones de normalidad establecidas por la sociedad. Así mismo, se refleja la invisibilización de la doble situación de fragilidad, dada por los mecanismos de exclusión social a los cuales son sometidas las personas con discapacidad.(AU)


ABSTRACT Objective To identify concrete and meaningful actions that establish the families of people with disabilities victims of forced displacement for (re)construction of social networks in the locality of Ciudad Bolivar in Bogota. Methodology Qualitative study with ethnographic approach. 5 meetings were heald with a focus group of 28 people victims of forced displacement, including people with disabilities and their caregivers and other members of their familes involved in social inclusion processes, inhabitants of the locality of Ciudad Bolivar. Results The results Indicate that the processes that allow the reconstruction of social networks there are framed in satisfaction of specific needs such as work, housing, education and nutrition, leaving significant aspects of participants life invisible. Conclusion Perception that exists about disability and displacement situation increases the social exclusion actions towards this population group by the regular society, which reflects the invisibility of the double situation of fragility.(AU)

ABSTRACT

PROBLEM: Providing skin-to-skin contact in the operating theatre and recovery is challenging. BACKGROUND: Barriers are reported in the provision of uninterrupted skin-to-skin contact following a caesarean section. AIM: To explore how health professionals' practice impacts the facilitation of skin-to-skin contact within the first 2h following a caesarean section. METHODS: Video ethnographic research was conducted utilising video recordings, observations, field notes, focus groups and interviews. FINDINGS: The maternal body was divided in the operating theatre and mothers were perceived as 'separate' from their baby in the operating theatre and recovery. Obstetricians' were viewed to 'own' the lower half of women; anaesthetists were viewed to 'own' the top half and midwives were viewed to 'own' the baby after birth. Midwives' responsibility for the baby either negatively or positively affected the mother's ability to 'own' her baby, because midwives controlled what maternal-infant contact occurred. Mothers desired closeness with their baby, including skin-to-skin contact, however they realised that 'owning' their baby in the surgical environment could be challenging. DISCUSSION: Health professionals' actions are influenced by their environment and institutional regulations. Further education can improve the provision of skin-to-skin contact after caesarean sections. Skin-to-skin contact can help women remain with their baby and obtain a sense of control after their caesarean section. CONCLUSION: Providing skin-to-skin contact in the first 2h after caesarean sections has challenges. Despite this, health professionals can meet the mother's desire to 'own' her baby by realising they are one entity, encouraging skin-to-skin contact and avoiding maternal and infant separation.

ABSTRACT

AIMS AND OBJECTIVES: To describe the challenges of, and steps taken to successfully collect video ethnographic data during and after caesarean sections. BACKGROUND: Video ethnographic research uses real-time video footage to study a cultural group or phenomenon in the natural environment. It allows researchers to discover previously undocumented practices, which in-turn provides insight into strengths and weaknesses in practice. This knowledge can be used to translate evidence-based interventions into practice. DESIGN: Video ethnographic design. METHODS: A video ethnographic approach was used to observe the contact between mothers and babies immediately after elective caesarean sections in a tertiary hospital in Sydney, Australia. Women, their support people and staff participated in the study. Data were collected via video footage and field notes in the operating theatre, recovery and the postnatal ward. CONCLUSIONS: Challenges faced whilst conducting video ethnographic research included attaining ethics approval, recruiting vast numbers of staff members and 'vulnerable' pregnant women, and endeavouring to be a 'fly on the wall' and a 'complete observer'. There were disadvantages being an 'insider' whilst conducting the research because occasionally staff members requested help with clinical tasks whilst collecting data; however, it was an advantage as it enabled ease of access to the environment and staff members that were to be recruited. Despite the challenges, video ethnographic research enabled the provision of unique data that could not be attained by any other means. RELEVANCE TO CLINICAL PRACTICE: Video ethnographic data are beneficial as it provides exceptionally rich data for in-depth analysis of interactions between the environment, equipment and people in the hospital environment. The analysis of this type of data can then be used to inform improvements for future care.

ABSTRACT

Esta dissertação apresenta uma reflexão antropológica acerca da prática da hipnose. Para tanto, a pesquisa se dividiu em duas partes. A primeira, uma reflexão que parte de dois momentos controversos da história da hipnose com o intuito de delinear alguns conceitos e problemas centrais tanto para a definição da experiência da hipnose quanto para a dificuldade de sua legitimação social enquanto objeto de conhecimento científico. A segunda parte procura apresentar uma reflexão etnográfica sobre a prática da hipnose entre terapeutas alternativos. Estabelece uma caracterização geral do campo, delineia seu grau de dispersão relativo ao próprio caráter marginalizado da prática. Esboça uma explicação das diferentes estratégias de legitimação frente ao campo fragmentado. E finalmente apresenta um relato da experiência em um curso de hipnose terapêutica no qual são descritos alguns procedimentos que nos aproximam do discurso contemporâneo dos hipnólogos, o objeto de seu saber e sua forma de produção de experiência subjetiva.(AU)


Abstract : This work presents an anthropological reflection on the practice of hypnosis. In the way of doing that, research was divided into two parts. The first, a reflection that has its start point in two controversial moments in the history of hypnosis in order to outline some central concepts and problems, both to definition of the experience of hypnosis as to the difficulty of its social legitimacy as a scientific object of knowledge. The second part seeks to present an ethnographic reflection on the practice of hypnosis among alternative therapists. Establishes a general characterization of the field, outlining their degree of dispersion relative to itself marginalized nature of the practice. Sketches an explanation of the different legitimation strategies across the fragmented field. And finally, it presents a report of an experience on a course of therapeutic hypnosis in which some procedures that bring us close to the contemporary discourse of hypnotists are described, the object of his knowledge and his way of producing subjective experience.(AU)

ABSTRACT

A relação entre o clima e a saúde do idoso urbano tem sido amplamente abordada em termos quantitativos. Esta pesquisa busca compreender como se constitui a relação dos idosos com o clima no cotidiano urbano e em seu contexto cultural, buscando contribuições para o tema da adaptação em tempos de mudanças climáticas, ao fenômeno da ilha de calor urbana, e para o entendimento sobre o envelhecer na cidade. O objetivo foi compreender como os idosos moradores do centro de São Paulo, Brasil, experimentam e relatam sua experiência sobre o tempo meteorológico e o clima no cotidiano, tanto na vida doméstica quanto na sua movimentação pelo espaço público, integrando perspectivas físicas, subjetivas e ambientais. Trata-se de pesquisa qualitativa, de perspectiva etnográfica e com orientação analítico-descritiva, que utiliza como técnicas de coleta de dados a observação participante, entrevistas semiestruturadas e análise de documentos. A interpretação do material coletado seguiu os pressupostos da análise temática e manteve o foco em práticas sociais. Os participantes da pesquisa revelaram uma relação complexa com o clima e tempo, explicitada por meio da prática narrativa de memórias sociais que elaboram uma construção de clima e, simultaneamente, das práticas antecipatórias e adaptativas às condições atmosféricas que se apresentam no cotidiano. Esta experiência revelou-se corporificada e situada tanto no plano concreto do urbano quanto no plano subjetivo do histórico e social.


Introduction - The relationship between climate, health and the urban elderly has been widely discussed in quantitative terms. This research seeks to understand how the relationship with climate is built into the everyday life of the elderly who live in cities within their historical, social and cultural context. It aims to generate contributions to the issue of adaptation to climate change, to an urban heat island environment and the debate on aging in big cities. The main objective was to understand how the elderly residents of the center of São Paulo, Brazil, experience and report the experience about weather and climate in daily life, both in domestic and public spaces, integrating physical, subjective and environmental perspectives. This is a qualitative research with an ethnographic approach and an analytical-descriptive orientation, using the techniques of participant observation, semi-structured interviews and document analysis for data generation. The interpretative approach follows the assumptions of thematic analysis and the focus on practices. The participants have revealed a complex relationship with climate and weather: from constructions of climate that emerged during narrative practice of social memories, to anticipatory and adaptive practices to atmospheric conditions they had to deal with in everyday life. The experience has proved to be embodied and emplaced both in the concrete urban dimension and in the subjective dimension of the historical and social context.

ABSTRACT

The Outline for Cultural Formulation (OCF) in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) marked an attempt to apply anthropological concepts within psychiatry. The OCF has been criticized for not providing guidelines to clinicians. The DSM-5 Cultural Issues Subgroup has since converted the OCF into the Cultural Formulation Interview (CFI) for use by any clinician with any patient in any clinical setting. This paper presents perceived barriers to CFI implementation in clinical practice reported by patients (n = 32) and clinicians (n = 7) at the New York site within the DSM-5 international field trial. We used an implementation fidelity paradigm to code debriefing interviews after each CFI session through deductive content analysis. The most frequent patient threats were lack of differentiation from other treatments, lack of buy-in, ambiguity of design, over-standardization of the CFI, and severity of illness. The most frequent clinician threats were lack of conceptual relevance between intervention and problem, drift from the format, repetition, severity of patient illness, and lack of clinician buy-in. The Subgroup has revised the CFI based on these barriers for final publication in DSM-5. Our findings expand knowledge on the cultural formulation by reporting the CFI's reception among patients and clinicians.

ABSTRACT

O Brasil está entre os principais exportadores de poaia [Psychotria ipecacuanha (Brot.) Stoves] seguido do Panamá e Costa Rica. A poaia brasileira apresenta alto valor farmacológico das raízes devido aos teores de emetina e cefalina. Este trabalho teve como objetivo descrever como as famílias de poaieiros mantém a memória cultural sobre a Psychotria ipecacuanha (Brot.) Stoves. As informações foram coletadas no município de Cáceres, Mato Grosso, através de entrevista estruturada e observação participante com 20 homens e 10 mulheres, de faixa etária de 45 a 86 anos. Foram citadas as formas de utilização na alimentação para animais, inseticida, carrapaticida, emético, contra diarréias, para alívio de dor de cabeça, contra malária, bronquite e dor no estômago. A raiz é a parte mais usada e a forma de preparo é tintura ou misturada ao fumo, ao vinho ou à cachaça. Poucos entrevistados passaram aos filhos o conhecimento sobre a P. ipecacuanha. A memória cultural sobre a P. ipecacuanha deve-se a vivência, extração e comercialização da planta, e por ouvir as conversas dos pais com amigos. A perda de conhecimento associado a poaia é causada pelo êxodo rural, destruição do habitat com o desmatamento e ocupação agrícola. A extinção da espécie na região contribui para a erosão cultural.


Brazil is among the leading exporters of ipecac [Psychotria ipecacuanha (Brot.) Stoves], followed by Panama and Costa Rica. The roots of Brazilian ipecac have high pharmacological value due to their levels of emetine and cephalin. This study aimed to describe how families of "poaieiros" maintain the cultural memory of Psychotria ipecacuanha (Brot.) Stoves. Information was collected in the city of Cáceres, Mato Grosso State, Brazil, through structured interviews and participating observation involving 20 men and 10 women aged from 45 to 86 years. The cited forms of use were in animal nutrition, as insecticide, acaricide, emetic, against diarrhea, relief from headache, and against malaria, bronchitis and stomach ache. The root is the most used part and its preparation form is tincture or mixed with tobacco, wine or sugarcane. Few interviewees transmitted to their children the knowledge of P. ipecacuanha. The cultural memory of P. ipecacuanha is due to experience, extraction and marketing of the plant, as well as to hearing conversations between parents and friends. The loss of knowledge associated with ipecac is caused by rural exodus, destruction of its habitat due to deforestation and agricultural occupation. The extinction of this species in the region contributes to cultural erosion.

ABSTRACT

SenseCam is a wearable digital camera that captures an electronic record of the wearer's day. It does this by automatically recording a series of still images through its wide-angle lens, and simultaneously capturing a log of data from a number of built-in electronic sensors. Subsequently reviewing a sequence of images appears to provide a powerful autobiographical memory cue. A preliminary evaluation of SenseCam with a patient diagnosed with severe memory impairment was extremely positive; periodic review of images of events recorded by SenseCam resulted in significant recall of those events. Following this, a great deal of work has been undertaken to explore this phenomenon and there are early indications that SenseCam technology may be beneficial to a variety of patients with physical and mental health problems, and is valuable as a tool for investigating normal memory through behavioural and neuroimaging means. Elsewhere, it is becoming clear that judicious use of SenseCam could significantly impact the study of human behaviour. Meanwhile, research and development of the technology itself continues with the aim of providing robust hardware and software tools to meet the needs of clinicians, patients, carers, and researchers. In this paper we describe the history of SenseCam, and the design and operation of the SenseCam device and the associated viewing software, and we discuss some of the ongoing research questions being addressed with the help of SenseCam.

ABSTRACT

PURPOSE: This article offers a discussion about the use of focused ethnography and the community readiness model to study disability at the community level in cross-cultural or international settings. It describes lessons learned when applying these methods to inform community-based disability programming in remote, rural villages in Ladakh, India. METHODS: Data were collected from 30 persons with disabilities, family members and community leaders in four remote villages using interviews and participant observation. All interviews were analysed qualitatively using a mix of inductive and deductive techniques. Community readiness interviews were scored using anchored rating scales to determine level of 'readiness' to take action on meeting the needs of persons with disabilities. Following the initial assessment, community workshops were used to disseminate results and facilitate local engagement in planning and intervention. RESULTS: There were minor challenges and significant benefit in the application of these two approaches in Ladakh; outcomes included: a known level of community readiness that can be used to improve targeting of appropriate community-based intervention and assess change over time, identification of salient needs, barriers and facilitators for persons with disabilities and their families; and community-level engagement during and following the research. CONCLUSIONS: Research models with participatory components like focused ethnography and community readiness hold significant promise for planning and evaluating community-based disability programmes.

ABSTRACT

A new optoelectronic system based on a projection unit in which light, coming from a laser diode coupled to an optic fiber impinges on a diffractive optical element (DOE) to produce sinusoidal fringes is proposed for three-dimensional (3-D) texture measurement. If the projected fringe pattern is viewed at an angle different from the projection angle, the fringe profile is phase-modulated by the 3-D object shape. The 3-D map information is obtained with the aid of a fringe analyzer based on phase-shifting synthetic moiré pattern, Fast Fourier Transform (FFT), signal demodulation techniques and a robust and fast phase unwrapping performed by a specially developed software. The proposed system is based on a simple and low cost equipment; furthermore, it is suitable for in situ measurements also by nonskilled operators. Some experimental examples illustrate its performance.

ABSTRACT

The use of a portable NMR device allows a non-invasive investigation of the paper in order to assess the state of conservation of books and documents of historical or artistic interest. The NMR investigation has been found mainly on relaxation measurements whose results seem compatible with different relaxation rates in crystalline and amorphous cellulose domains. By a simplified physical picture based on spin-diffusion it appears possible to detect the alteration of the crystalline/amorphous cellulose balance and therefore to get information on some deterioration processes of paper. The use of a portable NMR device shows great potentiality because of its safe and simple in situ approach to Cultural Heritage documents. In this work, we present a research carried out on a 17th century manuscript.
