Scientific Rigor (scientific + rigor)
Selected Abstracts"The probable industrial origin of archaeological daub at an Iron Age site in northeast Thailand" (Parr and Boyd, 2002): A comment on the inappropriate application of geophysical and geochemical techniques to an archaeological questionGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 8 2003Maria Cotter Parr and Boyd (2002) used colorimetric analysis in combination with geophysical and geochemical techniques to estimate firing temperatures for archaeological daub from an Iron Age site in Thailand. They suggest that the daub was fired at high temperatures and, therefore, is indicative of kiln utilization and increased industrialization during that period in Thailand. They argue that the adoption of a multimethod analytical approach in which the combination of data derived from ICP-MS, X-ray diffraction, and magnetic susceptibility analyses of daub samples, coupled with microscopic and macroscopic examination of samples, enhances the accuracy of their interpretations. While they should be commended for attempting to substantiate their claims using many geophysical and geochemical techniques, their arguments are flawed by the misapplication of the techniques described and/or over-interpretation of the data generated by such techniques. Therefore, Parr and Boyd's (2002:285) point about methodology ("that the combined interpretation of independent measures provides a better estimate of the original firing temperatures of the archaeological material than has hitherto been possible") is made redundant by the lack of scientific rigor applied to the independent measures used for this study. © 2003 Wiley Periodicals, Inc. [source] Cluster headache: the challenge of clinical trials.HEADACHE, Issue 3 2003K Moore Curr Pain Headache. Rep 2002 Feb;6(1):52-56 The design and execution of clinical trials poses special problems for cluster headache. Although there is less inter-individual and intra-individual variability of attacks than seen with migraine, the brevity of attacks, spontaneous remissions unrelated to treatment, and the relative rarity of cluster headaches challenge investigators. The International Headache Society has developed guidelines that represent a compromise between scientific rigor and practicality. Only injectable sumatriptan for acute attacks and verapamil for prophylaxis have demonstrated a robust therapeutic effect in controlled clinical trials. Comment: Kenneth Moore raises important methodological considerations. It is possible to undertake crossover trials comparing different active treatments? He is correct in his assertion that few agents show robust efficacy. A major issue relates to the proportion of patients with episodic versus chronic cluster headache where efficacy of active treatments can vary. For example, oral zolmitriptan was effective against placebo only in those patients with episodic disease (Bahra A, Gawel MJ, Hardebo JE, Millson DS, Breen SA, Goadsby PJ. Oral zolmitriptan is effective in the acute treatment of cluster headache. Neurology. 2000;54:1832-1839). And a set of small studies on melatonin and cluster demonstrate the problems Dr. Moore describes. In one study (Leone M, D'Amico D, Moschiano F, Fraschini F, Busonne G. Metalonin versus placebo in the prophylaxis of cluster headache: a double-blind pilot study with parallel groups. Cephalalgia. 1996;16:494-496), the melatonin worked only in episodic, not chronic cluster patients. In the second study (Prinsheim T, Magnoux E, Dobson CF, Hamel E, Aube M. Melatonin as adjuctive therapy in the prophylaxis of cluster headache: a pilot study. Headache. 2002;42:787-792), melatonin did not work better than placebo in either episodic or chronic cluster patients. Furthermore, the paper abstracted above by Torelli and Manzoni suggests that episodic cluster may progress to chronic cluster as a result of extrinsic factors such as smoking. Finally, there are ethical issues in placebo-controlled cluster studies, given the severity of the pain and the availability of effective acute and chronic treatments. As noted above, Dr. Peter Goadsby points out the need to persevere with these studies to find nonvasoactive treatments for patients with cluster headache. DSM and SJT [source] A modest proposal: a testable differentiation between third- and fourth-order information complexityINTERNATIONAL JOURNAL OF APPLIED PSYCHOANALYTIC STUDIES, Issue 4 2006Kathryn Cason Abstract In Human Capability, Jaques and Cason (1994) described the importance of the Third and Fourth Orders of Information Complexity used by adults working to create and manage our commercial endeavors, govern our countries, and provide services such as healthcare and education to our populations. Today our knowledge of these two Orders is still in descriptive terms, therefore less subject to testing than meets the necessary scientific rigor. In order to pursue a better understanding of how to more effectively educate and employ this capability in the adult population it is necessary to have clarity about the boundaries of these apparently discontinuous innate human "processes." The authors here set out important aspects of their continued inquiry. Copyright © 2006 John Wiley & Sons, Ltd. [source] Community intervention and public policy in the prevention of antisocial behaviorTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 1-2 2009Kenneth A. Dodge As academic clinical science moves to community intervention to achieve impact on population prevalence of antisocial behavior disorders, exciting potential is tempered by realistic caution. Three kinds of efforts are noted. First, individual evidence-based therapies are being implemented at scale. Difficulties in high-fidelity implementation are noted, and the unlikelihood of population impact is highlighted. Second, communities are receiving new resources to support individuals, although connecting community resources to highest-risk individuals is difficult. Third, community factors are being targeted for change through policy reform, with mixed results. As the field moves in this direction, the importance of adhering to principles of scientific rigor and empirical evidence is emphasized, to keep scientist-practitioners from overstepping their bounds. [source] Stakeholder engagement opportunities in systematic reviews: Knowledge transfer for policy and practiceTHE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue 2 2008Kiera Keown MSc Abstract Knowledge transfer and exchange is the process of increasing the awareness and use of research evidence in policy or practice decision making by nonresearch audiences or stakeholders. One way to accomplish this end is through ongoing interaction between researchers and interested nonresearch audiences, which provides an opportunity for the two groups to learn more about one another. The purpose of this article is to describe and discuss various stakeholder engagement opportunities that we employ throughout the stages of conducting a systematic review, to increase knowledge utilization within these audiences. Systematic reviews of the literature on a particular topic can provide an unbiased overview of the state of the literature. The engagement opportunities we have identified are topic consultation, feedback meetings during the review, member of review team, and involvement in dissemination. The potential benefits of including stakeholders in the process of a systematic review include increased relevance, clarity, and awareness of systematic review findings. A further benefit is the potential for increased dissemination of the findings. Challenges that researchers face are that stakeholder interactions can be time- and resource-intensive, it can be difficult balancing stakeholder desires with scientific rigor, and stakeholders may have difficulties accepting findings with which they do not agree. Despite these challenges we have included stakeholder involvement as a permanent step in the procedure of conducting a systematic review.
