Intellectual property rights and the campaign for access to essential medicines : the advocacy role assumed by Médecins Sans Frontières

Non-governmental organizations and transnational networks have been increasingly successful a t gaining influence within issue areas traditionally controlled by the state. In many instances, non-state actors have been instrumental in forcing issues onto the global agenda, have aided in the development or transformation of global regimes, and have participated in securing state compliance for the adoption of new international norms. This paper argues that, consistent with social constructivist theory, ideas are important in influencing state preferences and change may be possible when certain factors are present. I f non-state actors can influence states, it is meaningful to understand how this happens. This paper focuses on a campaign led by Medecins Sans Frontieres that began in the late 1990s to acquire affordable medicines for patients in developing states that could not afford patented drugs. The campaign reached a measure of success in that member states of the World Trade Organization re-negotiated contested terms and meanings within the trade agreement for intellectual property rights and allowed concessions that would benefit lower income states. What factors contributed to the success of the campaign? And what were the most important factors - the issue, the actors or the mechanisms used?

Exploring perspectives about sexuality among Ghanaian youth living in Canada: Understanding the impact of cultural contact.

Research on sexuality in Ghana has been scanty due to the nature of the Ghanaian society where sensitive issues like sexuality are not openly discussed and researched. This qualitative study examined how social contact with Canadian society has impacted the views of Ghanaian students living in Canada about sexuality. The data for this research study were gathered through in-depth interviews with 15 Ghanaian students between ages18 to 30 who had been living in Canada for more than one year. This study’s findings revealed that religion plays a central role in shaping views about sexuality among young Ghanaians living in Canada. The findings also highlighted the impact of cultural contact in shaping several aspects of sexuality including contraception and same-sex relations. The theoretical implications of this study’s results are discussed in terms of how they can help to clarify culturally informed models focusing on the role played by society, religion, family and peers in the development of adolescent perspectives about sexuality. The practical and educational implications of this study’s results are also discussed.

Minimal Contact Intervention for Tobacco Dependence

This study was conducted to measure the degree of adherence by public health care providers to a policy that requires them to implement minimal contact intervention for tobacco cessation with their clients. This study also described what components of the intervention may have contributed to the adherence of the policy and how health care providers felt about adhering to the policy. The intervention consisted of a policy for implementation of minimal contact intervention, changes to documentation, a health care provider mentor trained, a training session for health care providers, and ongoing paper and people supports for implementation. Data for this study were collected through a health care provider questionnaire, focus group interviews, and a compliance protocol including a chart audit. The findings of this study showed a high degree of adherence to the policy, that health care providers thought minimal contact intervention was important to conduct with their clients, and that health care providers felt supported to implement the intervention. No statistically significant difference was found between new and experienced health care providers on 17 of the 18 questions on the health care provider questionnaire. However there was a statistically significant difference between new and experienced health care providers with respect to their perception that “clients often feel like they have to accept tobacco cessation information from me.” Changes could be made to the minimal contact intervention and to documentation of the intervention. Implications for future research include implementation within other programs within Hamilton Public Health Services and implementation of this model within other public health units and other types of health care providers within Ontario.

Registered Nurses' Perceptions about Facilitators and Barriers to Maternal Skin to Skin Contact in the Operating Room

Abstract It is recommended that all new mothers experience skin-to-skin contact (SSC) with their newborns immediately after birth. However, SSC is not commonly practiced after cesarean deliveries. To understand facilitators and barriers regarding SSC in the operating room (OR), a descriptive online and paper survey was conducted with 68 Registered Nurses from four hospitals in Ontario. The theory of planned behavior framed the study. Nurses had positive attitudes, and believed most health care team members supported SSC in the OR, but were uncertain about their control over the behavior. Nurses who had practiced the behavior in the past had more positive attitudinal and normative beliefs, and perceived some barriers as less difficult. Attitude and past behavior were the only significant multivariate predictors of intention to practice SSC in the future. Results suggest that shifting attitude and supporting more experience with the practice may increase nurses’ implementation of SSC in the OR.
