This paper will examine the use of quantitative and qualitative methods as complementary research methods. It asks the fundamental question whether these two approaches can be used jointly in a principled manner. The pressure in educational research has been towards using the two methods alongside each other. In applied research the use of the two approaches in the same project is accepted yet ...

The Latin American Calculators in Mathematics Education Project (PLACEM) is experimenting with the use of calculators in mathematics teaching in seven Latin American countries: Argentina, Brazil, Chile, Colombia, Dominican Republic, Mexico and Venezuela. PLACEM has received calculators and some financial support from Texas Instruments. There has been only minor resistance to calculator use, and...

Transformational leadership, initiating structure, and selected substitutes for leadership were studied as longitudinal predictors of performance in 118 research and development (R&D) project teams from 5 firms. As hypothesized, transformational leadership predicted 1-year-later technical quality, schedule performance, and cost performance and 5-year-later profitability and speed to market. Ini...

Complementing the broader project of treating human subjects research regulation (including “informed consent”) as an ethnographic object, this article scrutinizes the category research: that about which research subjects may (in some way) be informed, to which they may (or may not) consent, and in which they may (variously) participate. What is “research”? When does it begin and end? What is t...

Addressing genetics, risk modeling, molecular targets for chemoprevention, clinical prevention trials, behavioral prevention research, public policy, and more, the Fifth Annual International Conference on Frontiers in Cancer Prevention Research, held in Boston, Massachusetts, in November 2006, added an outstanding new chapter to the landmark AACR Frontiers program for advancing the science and ...

Iran has recently made a significant progress in the field of biomedical science and launched an appreciable number of new high-tech biomedical research projects. Review of Iran's experience in advancing its biomedical research and the pitfalls the country encountered during the years of its progress could be of interest to other countries with similar technological conditions. As needs assessm...

Throughout many parts of the world, biomedical research ethics is based on a core body of well-established norms, rules, and principles, including the Declaration of Helsinki, the Nuremberg Code, the Belmont Report, and the International Ethical Guidelines for Biomedical Research Involving Human Subjects (1). The overarching goal of these codifications is to protect people against harms arising...

INTRODUCTION Allied health professionals (AHPs) report positive attitudes to using research evidence in clinical practice, yet often lack time, confidence and skills to use, participate in and conduct research. A range of multifaceted strategies including education, mentoring and guidance have been implemented to increase AHPs' use of and participation in research. Emerging evidence suggests th...

Operations research (OR) focuses on the application of analytical methods to facilitate better decision-making. Despite its usefulness and proliferation of papers in the academic literature, there are still major issues around getting OR models widely accepted and used as part of mainstream decision-making by clinicians, health managers and policy-makers. This article aims to raise the awarenes...
