The article studies the differences in knowledge production between academic researchers. In this perspective, it attempts at first to answer the following question: what factors explain differences in knowledge production between Canadian researchers in natural sciences and engineering? After a presentation of some of the empirical evidence…

This paper explores how Fourier Transform (FT) mimics spectral transformation, how this property can be exploited to advantage in spectroscopy, and how the FT can be used in data treatment. A table displays a number of important FT serial/spectral pairs related by Fourier Transformations. A bibliography and listing of computer software related to…

Discusses the physical basis and current understanding of hydrophobic effects. The thermodynamic background of the effects, hydrophobic hydration, and hydrophobic interactions are described. Four existing controversies are outlined. (YP)

The role of editors and peer reviewers in detecting and sanctioning scientific misconduct is analyzed, structural problems inherent in the process are examined, and best means of enabling peer and editorial roles in correction of misconduct are discussed. It is argued that the review process plays a limited corrective role. (MSE)

Discusses the role of dogs in research, considering their use in studies related to: behavior; aging; anesthesia; gastrointestinal surgery; the brain; organ transplants; radiobiology; trauma and shock; arterial diseases; hemophelia; ophthalmology; diabetes; nutrition; cancer; lupus; cyclic neutropenia; thyroiditis; hepatitis; skeletal system,…

Outlines the chemistry of the rapid synthesis of relatively large DNA fragments (100-200 monomers each) with yields exceeding 99 percent per coupling. DNA synthesis methodologies are outlined and a polymer-supported synthesis of DNA using deoxynucleoside phosphoramidites is described with structural formulas. (YP)

Tested Richard Duschl's triadic model of the growth of scientific knowledge against research practices of 10 accomplished life scientists. Reports that the scientists were willing to change their aims, methods, or theories and were both realists and relativists depending on the scientific discourse about the phenomena in question. Discusses…

A discussion of resource allocation for scientific research identifies the ethical principles underlying the present debate and begins to construct a framework for evaluating various resource allocation proposals. The intent is to promote greater consideration of the link between ethics and science resource allocations. (Author/MSE)

A survey of 334 biochemists identified 5 patterns of attitudes and beliefs about taking action for scientific misconduct: (1) reputational harm, (2) sanction criteria, (3) whistleblower stigmatization, (4) professional etiquette, and (5) ideological desensitization. Influences of intraprofessional status, departmental cohesion, institutional…

The norms of science define appropriate and inappropriate scholarly or research role performance. The four norms described in this study are (1) universalism: research is assessed on its merit, not particularistic criteria; (2) commonality: research must be made public and shared with the research community; (3) disinterestedness: research is…

Reports on a 30-year-old longitudinal study of reactions in gels. Described are reactions and crystal growth in silica gels and diffusion studies of the Liesegang ring formation. Color photographs showing the reactions and graphs upon the diffusions are presented. (YP)

There is a tendency to use case-study research methodology for research issues aiming at simply describing a complex situation, and to draw conclusions with insufficient rigour. Sound case-study research, however, follows discriminate rules which can be described in all the dimensions of a full case-study research process. This paper examines…

The hypothesis is the device scientists use to translate questions, theories, or proposed explanations into a form amenable to empirical research. This edition of W. W. Charter's treatise on clear, conceptual definitions and precise operational hypotheses, which was originally developed to assist students in educational policy and management…

Discusses the unique user interface of Apple's Macintosh microcomputer which is changing the way researchers interact with their data. Topic areas addressed include: desktop, mouse, and windows; preparing scientific illustrations; MacPaint; and charts and graphics. Limitations are also noted. (DH)

Discusses issues and the public's concerns related to using laboratory animals for research purposes. Indicates that several perceptions (such as recognizing that the public's attitudes toward respect for animal life are no more irrational than many broader attitudes toward the sacredness of life) characterize the most responsible of recent…
