Rites of consent: negotiating research participation in diverse cultures.

The significance of informed consent in research involving humans has been a topic of active debate in the last decade. Much of this debate, we submit, is predicated on an ideology of individualism. We draw on our experiences as anthropologists working in Western and non Western (Iban) health care settings to present ethnographic data derived from diverse scenes in which consent is gained. Employing classical anthropological ritual theory, we subject these observational data to comparative analysis. Our article argues that the individualist assumptions underlying current bioethics guidelines do not have universal applicability, even in Western research settings. This is based on the recognition that the social world is constitutive of personhood in diverse forms, just one of which is individualistic. We submit that greater attention must be paid to the social relations the researcher inevitably engages in when conducting research involving other people, be this in the context of conventional medical research or anthropological field work. We propose, firstly, that the consenting process continues throughout the life of any research project, long after the signature has been secured, and secondly, that both group and individual dimensions of consent, and the sequence in which these dimensions are addressed, should be carefully considered in all cases where consent is sought.

Television, disordered eating, and young women in Fiji: negotiating body image and identity during rapid social change.

Although the relationship between media exposure and risk behavior among youth is established at a population level, the specific psychological and social mechanisms mediating the adverse effects of media on youth remain poorly understood. This study reports on an investigation of the impact of the introduction of television to a rural community in Western Fiji on adolescent ethnic Fijian girls in a setting of rapid social and economic change. Narrative data were collected from 30 purposively selected ethnic Fijian secondary school girls via semi-structured, open-ended interviews. Interviews were conducted in 1998, 3 years after television was first broadcast to this region of Fiji. Narrative data were analyzed for content relating to response to television and mechanisms that mediate self and body image in Fijian adolescents. Data in this sample suggest that media imagery is used in both creative and destructive ways by adolescent Fijian girls to navigate opportunities and conflicts posed by the rapidly changing social environment. Study respondents indicated their explicit modeling of the perceived positive attributes of characters presented in television dramas, but also the beginnings of weight and body shape preoccupation, purging behavior to control weight, and body disparagement. Response to television appeared to be shaped by a desire for competitive social positioning during a period of rapid social transition. Understanding vulnerability to images and values imported with media will be critical to preventing disordered eating and, potentially, other youth risk behaviors in this population, as well as other populations at risk.

Bifurcation in non-negotiable games: a paradigm for self-organisation in cognitive systems.

The interaction between two self-organising systems, each possessing two hierarchical levels, is dealt with. The communication process is pursued as a bidirectional information transfer. The criterion for the selection of the intrasystem control algorithm(s) is based on the maximisation of the 'Joint Figure of Merit' related to the long-term average of an appropriately weighted sum of conflicting terms: Probabilities of homeostases versus adequate matching with the partner.

African women and AIDS: negotiating behavioral change.

Trends in the incidence of HIV/AIDS infection among women in Sub-Saharan Africa suggest this population is increasingly at risk. Many of the same factors that have predisposed rural African women to ill health in the past now increase their vulnerability to AIDS, including poverty and malnutrition, uncontrolled fertility, and complications of childbirth. As men travel out from rural communities to urban centers in search of employment, their sexual contacts multiply; many will acquire the HIV virus and carry it back to infect wives at home. Women, too, are leaving rural areas for the promise of a better life in cities and commercial centers along the way. Their struggle for economic survival and personal autonomy has led many to form relationships with new sexual partners, with a consequent increase in HIV seroprevalence among women once considered at low risk of infection. This paper argues that AIDS prevention campaigns have not yet taken into account the cultural, social, and economic constraints on most African women's ability to comply with advice to limit partners and use condoms. The author proposes a research agenda to explore the meaning of AIDS and AIDS prevention in the sociocultural context of women's lives. A better understanding of how women, themselves, perceive and respond to current attempts to prevent the transmission of AIDS is an increasingly critical factor in the intervention process. Most important, it is a necessary first step toward their effective participation with men in the development of culturally relevant strategies for protecting themselves and their families.

Anxiety-mediated gait adaptations reduce errors of obstacle negotiation among younger and older adults: implications for fall risk.

The purpose of this study was to determine if anxiety-mediated gait adaptations can reduce the risk for falling among younger and older adults. Fourteen younger adults (23.14+/-3.08 years) and 14 older adults (69.28+/-5.41 years) participated in this study. Participants were asked to walk the length of a 7.20m walkway and avoid contact with an obstacle that appeared suddenly underfoot at either 25% or 75% of the gait cycle duration. Testing was conducted in four conditions of postural threat. The obstacle was presented as a light beam and did not jeopardize balance when contacted. Fall risk was inferred from the frequency of obstacle contacts. Our findings indicated that obstacle contact frequency decreased when conservative gait patterns emerged. These findings imply that anxiety-mediated gait adaptations are beneficial in reducing the risk for falling among older adults and present the possibility that fear of falling may offer protective benefits for postural control. One possibility is that the beneficial effects of anxiety can only be realized among older adults who do not fear falling.

Negotiating socialisation: the journey of novice nurse academics into higher education.

In this paper we seek to explore the socialisation process experienced by novice nurse academics when they make the transition from the health sector into the education sector. We will do this by identifying the theoretical tensions between individual freedom in the context of organisational needs. The ramifications of these tensions will be highlighted and solutions for raising awareness as to how to manage them are discussed. We conclude that a socialisation process that protects individual freedom and promotes self-development is one that carries the greatest benefit for the novice nurse academic and the educational institution.

Gaze fixation patterns for negotiating complex ground terrain.

We constantly encounter different ground terrain in our environment that we must safely traverse. The visual system is unique, as it is the only sensory system that can provide accurate and precise information about the environment at a distance through a series of fixations directed to salient objects and/or surfaces. However, how the nervous system utilizes visual information regarding complex ground terrain to guide safe foot placement is not known. We had individuals walk across a walkway with varying ground terrain while gaze fixations were monitored. Several findings emerged. First, gaze fixations were highly task-relevant in that they were predominantly made to areas eventually stepped on and their patterns tended to depend on the task instructions. Second, fixations were frequently directed to a transition region between different surfaces in addition to fixations directed to an actual surface. These results suggest that fixations are directed to regions that maximize the amount of information which the nervous system can integrate in order to facilitate safe foot placement. And third, spatial information of the upcoming ground terrain was sampled sequentially in small sections and continuously updated as the individual traversed the challenging ground terrain. This is suggestive of on-line control and may be beneficial to ensure one is able to adapt to stability concerns, unexpected changes in terrain, or sudden changes in the path taken.
