While health promotion practitioners are engaging increasingly in research,
there has been little examination of the practical dilemmas they may face
in negotiating and collaborating with academics and community members in
action research projects. This paper analyses how the practice of health
promotion can interact with action research, and considers issues that
arise for organizationally based health promotion practitioners and
professional researchers. The first section charts types of action research
along three dimensions (power, goals/values, resources). The second section
examines some of the issues and practical dilemmas which arise in
negotiating and researching collaborative projects in community health
promotion. The discussion includes the differing perspectives of:
practitioners (managerial and frontline), community members and academic
researchers. The final section outlines a hybrid model of action research,
developed in our work with community members, organizationally based health
promoters and academy-based researchers. It combines the reflective
practice of practice-based action research with the community participation
and control of participatory research. The model is called community
reflective action research. 相似文献

Nine strains of Oryzaephilus surinamensis have been kept in laboratory culture for periods ranging from 5 to 30 years (30–180 generations). Two RAPD primers provided sufficient information to separate the strains reliably and unambiguously. The strains are maintained at a population size of 200 breeding adults. The marked divergence between strains is consistent with the small population size, which for the older strains, according to population genetics theory, implies that roughly half the original genetic variation should now be lost from within strains. However, there is no indication that the older strains have less inter-strain variation. The results demonstrate RAPD loci can reliably detect population subdivision, which in field populations of pest species is of fundamental importance in understanding the population genetics of insecticide resistance. 相似文献

The role of arthroscopy in the problem total knee replacement 总被引:2,自引:0,他引:2
Fourteen patients were retrospectively reviewed to examine the role of arthroscopy in the diagnosis and treatment of the problem total knee arthroplasty (TKA), and to define parameters for indications, techniques, and results. All patients had undergone a previous TKA, and postoperatively had problems with pain and/or range of motion. Routine evaluation failed to reveal sepsis or aseptic loosening. Arthroscopy was used to evaluate and treat certain specific conditions. The arthroscope was successful in removing loose bodies, correcting patella subluxation with an arthroscopic lateral release, excising a symptomatic pseudomeniscus, and releasing intraarticular adhesions to improve motion and relieve pain. The postoperative knee score improved 73%. Arthroscopy is a valuable tool to evaluate a painful TKA, and can be used to treat certain conditions that would otherwise require an arthrotomy. The rehabilitation time is easier on the patient and much quicker. Arthroscopy of a TKA does not compromise any future procedures. However, it remains a technically demanding procedure whose indications and expectations are still being defined. 相似文献
