Nigeria's oil guarantees its role in the global economy; however, the state's overwhelming weaknesses perpetuate a high level of volatility vis-à-vis the potential for an immediate disruption of the national, regional, and global environment. This study presents a current qualitative analysis of Nigeria to produce a model that characterizes current conditions in the state and the state response to the nefarious acts in the delta region. This model will serve as a baseline for a significant iteration of the model that reflects the delta region counter-insurgency at various levels of strength: a what-if scenario of the region with an increase of state security over southern separatists, insurgents seeking to gain control of the oil assets. The conjectured model serves to inform/educate decision and policy makers in developing proactive, effective strategies to counter existent and potential threats in the Niger Delta.  相似文献

Research ethics is often understood by researchers primarily through the regulatory framework reflected in the research ethics review process. This regulatory understanding does not encompass the range of ethical considerations in research, notably those associated with the relational and everyday aspects of human subject research. In order to support researchers in their effort to adopt a broader lens, this article presents a “person-oriented research ethics” approach. Five practical guideposts of person-oriented research ethics are identified, as follows: (1) respect for holistic personhood; (2) acknowledgement of lived world; (3) individualization; (4) focus on researcher-participant relationships; and (5) empowerment in decision-making. These guideposts are defined and illustrated with respect to different aspects of the research process (e.g., research design, recruitment, data collection). The person-oriented research ethics approach provides a toolkit to individual researchers, research groups, and research institutions in both biomedical and social science research wishing to expand their commitment to ethics in research.  相似文献

In recent times, China has significantly reduced hunger in its populace. The main objective of this paper was to analyze some of the contextual socioeconomic factors contributing to the reduction of hunger in China, using Qualitative Interpretative Meta‐Synthesis (QIMS). The results revealed that China has followed a broad‐based and multispectral approach to reduce hunger. Factors, such as poverty alleviation; social safety nets for disadvantaged villagers; agricultural development and land reforms; regional development and equity in development activities; infrastructural development; and political‐economic reform and sustainable growth were influential in reducing hunger in China. Poverty is attributed as one of the principal contributors and is interlinked with many other dimensions. The findings of this paper are a useful guide to the Chinese government, policy‐makers, international organizations, and development practitioners.  相似文献

Through the use of qualitative data analysis of in‐depth interviews with eight white international transracial adoptive mothers, four properties emerged that describe these mothers' racial views. These properties varied in the degree that they integrated perspectives different from the white dominant culture. The mothers did not experience significant changes in their perspective on race subsequent to adoption. This paper includes a discussion of white racial identity and implications for social work practice with transracially adoptive parents.  相似文献

Mubangizi BC, Gray M. Putting the ‘public’ into public service delivery for social welfare in South Africa Int J Soc Welfare 2011: 20: 212–219 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of SocialWelfare. The privatisation of some essential services in South Africa has raised severe difficulties for those for whom the idea of fees for services is quite foreign and who, in any case, cannot afford to pay for services. The government has developed several initiatives to educate people about the need to pay for services provided by local government, the largest of which was the Masakhane fees‐for‐services campaign. This article describes two recent initiatives that seek to engage local citizen participation, namely, Integrated Development Plans and izimbizo (or traditional forums). These are examined along with the challenges faced by local government in promoting citizenship participation in service delivery within a decentralised system of governance. The article concludes with some recommendations on how citizen participation can be enhanced so as to make the ‘public’ visible in public service delivery and thus improve social welfare services.  相似文献
