In our previous article on threats to internal validity of multiple baseline design variations (Slocum et al., 2022), we argued that nonconcurrent multiple baseline designs (NCMB) are capable of rigorously demonstrating experimental control and should be considered equivalent to concurrent multiple baselines (CMB) in terms of internal validity. We were fortunate to receive five excellent commentaries on our article from experts in single-subject research design—four of whom endorsed the conclusion that NCMBs should be considered strong experimental designs capable of demonstrating experimental control. In the current article, we address the most salient points made in the five commentaries by further elaborating and clarifying the logic described in our original article. We address arguments related to classic threats including maturation, testing and session experience, and coincidental events (history). We rebut the notion that although NCMBs are strong, CMBs provide an increment of additional control and discuss the application of probability-based analysis of the likelihood of threats to internal validity. We conclude by emphasizing our agreement with many of the commentaries that selection of single-case experimental designs should be based on the myriad subtleties of research priorities and contextual factors rather than on a decontextualized hierarchy of designs.  相似文献

本文从有关研究证据的基础上,介绍了个人化设计的理论基础和实验设计,并在此基础上讨论了个人化设计在临床研究领域中的应用价值,总结出一种适合临床病人使用的研究程序。个人化设计允许对个体的个人价值进行分析,并能同时研究不同刺激信息的作用,在个体水平上分析个体差异。通过简化了的实验程序,个人化设计为解决临床研究中的问题提供了一种新的思维方式。文中还对相关研究法的局限进行了讨论。  相似文献

Objective To assure that Healthy Communities are achieved, a tracking methodology is proposed using four health improvement categories. Methods Counties are classified as having met or not met nine HP2010 mortality targets and as improving or not improving, creating four categories of community health improvement – static, progressing, exemplary, and maintaining. Results Exemplary counties make up 1.7%32.7% of counties, counties have both improved and met the HP2010 target during the period. Across all indicators, a large proportion remains of counties that have neither met the HP2010 target nor improved (33.572.8%). Conclusions Understanding why, how, and in what ways communities move from static to maintaining categories is necessary to guiding every local public health system to community health improvement.  相似文献

This series of articles covers scholarly works in English which can, at least potentially, be associated with a generally positive view of biblical historicity regarding periods preceding the Israelites’ return from exile. Part 2 covers works that treat the methodological issues at the center of the maximalist–minimalist debate. Parts 3–5 will cover works on evidences.

This article completes the coverage, begun in the preceding article, of works that are neither maximalist nor minimalist, by treating select publications of Anthony J. Frendo, Nadav Na’aman, Israel Finkelstein, Andrew G. Vaughn, Baruch Halpern, Robert D. Miller II, and H. G. M. Williamson.

It then discusses works on methodology by authors who espouse biblical historicity unless it is proven wrong, who are often called maximalists. It introduces these through the comments of Craig G. Bartholomew, then treats select works by Kenneth A. Kitchen, Jens Bruun Kofoed, Richard E. Averbeck, Iain W. Provan, V. Philips Long, and James K. Hoffmeier.  相似文献

This qualitative study explored the experiences of five men and one woman who were parents, substance dependent, and receiving treatment. Data collected by observation and in-depth interviewing were analyzed using constant comparison method and thematic analysis. Findings were grouped into three categories: surviving my childhood and becoming an adult, the struggles of trying to be a parent, and the roles of spouses and extended family members. An overarching metathematic category, the destructive path and powerful appeal of addiction, describes why the participants reported feeling most comfortable in the role of drug addict and found order in the chaos in the addictive lifestyle.  相似文献

Abstract

Why is replicating cognitive neuroscience results so difficult? Here we discuss a possible bias that could determine the systematic omission of control variables. A methodology based on the notion that cognitive processes are encapsulated undermines the adequate characterization of both the sample and its experimental context. Systematically exploring the impact of the sample and context variables implies discussing and developing standard experimentation practices. We propose actively searching for unexpected results as a starting point to do so.  相似文献

Providing an overview of Integral Ecology, this article defines and explains some of the key terms and concepts that underlie an approach to the environment that is inspired by and makes use of Ken Wilber's Integral Theory. First Integral Ecology is distinguished from other environmental approaches. Then Wilber's Integral Theory is introduced, which provides a foundation for a participatory approach to ecology. Next, the ontology, epistemology, and methodology of environmental phenomena is examined in light of Wilber's framework and illustrated with multidimensional examples of recycling. Finally, an Integral Ecology platform is presented.  相似文献

Based on a comparative study, this paper highlights and analyses commonalities and differences between an Oriental systems approach, WSR, and two Western counterparts, TOP and MMD. It is suggested that cultural differences among systems approaches might probably have been overshadowed by both commonalities between Western and Eastern traditions and differences within the same cultural tradition. It will be further proposed that by being more consciously open to and learning from each other, systems approaches in the East and the West may have more to offer for dealing with the complexity which confronts humankind.  相似文献

Two common methods of measuring socioeconomic status (SES) were examined in relation to observed parenting behaviors in a clinical sample of 89 mothers of 3- to 6-year-olds referred for treatment of oppositional defiant disorder. Families were 74% Caucasian, 9% African American, 5% Hispanic, 1% Asian, and 11% Biracial. Most children were male (75%). Parenting behaviors were measured with the Dyadic Parent–Child Interaction Coding System (DPICS) categories of prosocial talk and negative talk. Analyses were conducted with SES measured in two ways: (a) the Hollingshead Four-Factor Index of Social Status (HI) was correlated with parenting behaviors; and (b) family income, parent education (5 categories), and parent occupation (5 categories) were used to predict parent behavior. SES was significantly positively related to maternal prosocial talk. When SES was operationalized as income, occupation, and education, the model predicted three times more variance in maternal prosocial talk than the HI alone. SES was not related to maternal negative talk by either measure of SES.  相似文献
