There is increasing interest in the need to address the ethical dilemmas related to the engagement of adolescents in sexual and reproductive health (SRH) research. Research projects, including those that address issues related to STIs and HIV, adverse pregnancy outcomes, violence, and mental health, must be designed and implemented to address the needs of adolescents. Decisions on when an individual has adequate capacity to give consent for research most commonly use age as a surrogate rather than directly assessing capacity to understand the issues and make an informed decision on whether to participate in research or not. There is a perception that adolescents participating in research are more likely to be coerced and may therefore not fully comprehend the risk they may be taking when engaging in research. This paper examines the various ethical issues that may impact stakeholders' decision making when considering engaging adolescents in SRH research in Nigeria. It makes a case for lowering the age of consent for adolescents. While some experts believe it is possible to extrapolate relevant information from adult research, studies on ethical aspects of adolescents' participation in research are still needed, especially in the field of sexual and reproductive health where there are often differences in knowledge, attitudes and practices compared to adults. The particular challenges of applying the fundamental principles of research ethics to adolescent research, especially research about sex and sexuality, will only become clear if more studies are conducted.  相似文献

Importance of basic research in applied phycology   总被引:1,自引:0,他引:1  
Magne  F. 《Hydrobiologia》1993,260(1):25-29
Utilization of algae has extended considerably from the middle of this century, with the consequence of more and more applied research in various directions and fields, the most important of which deals with phycocolloid production and algal cultivation to provide raw material and foodstuff. It is noteworthy that this research can not avoid the use of knowledge obtained by basic research; applied phycology is especially indebted to basic research in adopting biotechnologies which are typically coming from basic research. In counterpart, such a situation is beneficial to basic research. According to the dependence of applied phycology to basic research and the fact that restricted research programs only are nowadays financially supported, the fate of all research seems to be questionable.  相似文献

Synthetic biology is considered as an emerging research field that will bring new opportunities to biotechnology. There is an expectation that synthetic biology will not only enhance knowledge in basic science, but will also have great potential for practical applications. Synthetic biology is still in an early developmental stage in China. We provide here a review of current Chinese research activities in synthetic biology and its different subfields, such as research on genetic circuits, minimal genomes, chemical synthetic biology, protocells and DNA synthesis, using literature reviews and personal communications with Chinese researchers. To meet the increasing demand for a sustainable development, research on genetic circuits to harness biomass is the most pursed research within Chinese researchers. The environmental concerns are driven force of research on the genetic circuits for bioremediation. The research on minimal genomes is carried on identifying the smallest number of genomes needed for engineering minimal cell factories and research on chemical synthetic biology is focused on artificial proteins and expanded genetic code. The research on protocells is more in combination with the research on molecular-scale motors. The research on DNA synthesis and its commercialisation are also reviewed. As for the perspective on potential future Chinese R&D activities, it will be discussed based on the research capacity and governmental policy.  相似文献

Robert C. Hughes 《Bioethics》2014,28(8):397-404
It is widely agreed that foreign sponsors of research in low‐ and middle‐income countries (LMICs) are morally required to ensure that their research benefits the broader host community. There is no agreement, however, about how much benefit or what type of benefit research sponsors must provide, nor is there agreement about what group of people is entitled to benefit. To settle these questions, it is necessary to examine why research sponsors have an obligation to benefit the broader host community, not only their subjects. Justifying this claim is not straightforward. There are three justifications for an obligation to benefit host communities that each apply to some research, but not to all. Each requires a different amount of benefit, and each requires benefit to be directed toward a different group. If research involves significant net risk to LMIC subjects, research must provide adequate benefit to people in LMICs to avoid an unjustified appeal to subjects’ altruism. If research places significant burdens on public resources, research must provide fair compensation to the community whose public resources are burdened. If research is for profit, research sponsors must contribute adequately to the upkeep of public goods from which they benefit in order to avoid the wrong of free‐riding, even if their use of these public goods is not burdensome.  相似文献

HIV prevention is a critical health issue in Nigeria; a country that has one of the worst HIV epidemic profiles in the world. With 270,000 new infections in 2012, Nigeria is a prime site for HIV prevention research. One effect of the HIV epidemic has been to revolutionalise ethical norms for the conduct of research: it is now considered unethical to design and implement HIV related studies without community engagement. Unfortunately, there is very little commensurate effort in building the capacity of local persons to engage actively with researchers, and there is no existing platform to facilitate dialogue between researchers and communities engaged in research in Nigeria. In an effort to address this gap, we undertook a series of three community dialogues (Phase One) and two community‐researcher interface meetings (Phase Two) in Nigeria. This paper aims to give an empirical account of the dialogue from these community engagement processes and provide a resulting critique of the implementation of research ethics practices in Nigeria. It is anticipated that the outputs will: (i) support researchers in designing community‐based research protocols; (ii) inform ethics committees of key considerations during research protocol reviews from a community perspective; and (iii) inform policy makers and research sponsors about issues of primary concern to communities with respect to HIV research.  相似文献

Visual arts teachers engage in complex work on a daily basis. This work is informed by practical knowledge that is rarely examined or drawn on in research or in the development of policy. Focusing on the work of secondary visual arts teachers, this article reports on a research program conducted in a regional area of New South Wales, Australia. The research engages in a collaborative process of educational connoisseurship and educational criticism to examine and discuss classroom practice. The process is underpinned by a belief in research as an act of discovery and is guided by a framework that provides a language and grammar of practice. Drawing on qualitative data, discussion focuses on how the collaborative process enables the mobilization and generation of new knowledge. The article concludes by considering the relationship between teaching practice, research, and policy development and by recommending support for collaborative research-based initiatives that foreground the knowledge of teachers.  相似文献

Current perspectives in cancer proteomics   总被引:2,自引:0,他引:2  
Proteome technology has been used widely in cancer research and is a useful tool for the identification of new cancer markers and treatment-related changes in cancer. This article details the use of proteome technology in cancer research, and laboratory-based and clinical cancer research studies are described. New developments in proteome technology that enable higher sample-throughput are evaluated and methods for enhancing conventional proteome analysis (based on two-dimensional electrophoresis) discussed. The need to couple laboratory-based proteomics research with clinically relevant models of the disease is also considered, as this remains the next main challenge of cancer-related proteome research.  相似文献

Koren G 《Teratology》2002,65(4):191-195
BACKGROUND: The conduct of human research in the teratogenicity of drugs, chemicals, radiation and infections is needed in order to close critical gaps in knowledge. METHODS: We reviewed the various aspects of the ethics of conducting prospective human research in teratogenicity. RESULTS: Such research should respect the confidentiality of pregnant women and their families. Because this research is observational, interpretation of results is difficult, and the study design should strive to meet the highest possible scientific standards attainable in the particular research conditions. It should also be acknowledged that confidentiality cannot be always adhered to (e.g., if the interview reveals risks to minors). CONCLUSIONS: In general, the benefit risk ratio in this type of research is very favorable, although in specific cases the research follow-up may induce fears (e.g., drugs of abuse) in the woman being interviewed.  相似文献
