The recent commentary by Beaujean and Farmer (2020) on the original paper by Dixon et al. (2019) serves a cautionary tale of selective p-values, the law of small N sizes, and the type-II error. We believe these authors have crafted a somewhat questionable argument in which only 57% of the original Dixon et al. data were re-analyzed, based on a…

This commentary reflects on the contributions to learning analytics and theory by a paper that describes how multiple theoretical frameworks were woven together to inform the creation of a new, automated discourse analysis tool. The commentary highlights the contributions of the original paper, provides some alternative approaches, and touches on…

This essay examines the stages of inquiry when we seek to formulate quality of life in an era before our own. There arises the question of the extent to which today's formulation of quality of life can be applied to an era far removed from our own. Implicitly, there is the nature of the time interval, T[subscript 1]...T[subscript n], and the…

Ralph LaRossa's (2012) article on the multidimensional world of qualitative research provides family scientists with a set of innovative tools to guide writing and reviewing. He proffered an engaging challenge: to view the "Journal of Marriage and Family" ("JMF") as a meeting place of scholars, a thought community (Zerubavel, 1997), even a culture…

Content analysis has dominated computer-mediated communication and educational technology studies for some time, and a review of its practices applied to online corpus of data or messages is overdue. We are confronted with complexity given the various foci, nuances and models for theorising learning and applying methods. One common suggestion to…

I argue in this article that recognizing the role of subjectivity and bringing in the researcher's positionality as a tool in the research process can not only enhance the ethical integrity of the research but also enhance both the research process and the analysis and interpretation of the data. Cultural studies theorists have long argued that…

The author was invited to prepare a commentary in response to the Lev-Wiesel manuscript titled "Intergenerational Transmission of Sexual Abuse? Motherhood in the Shadow of Incest." Lev-Wiesel's stated intent in the study was to understand an important issue, namely how is intra-familial sexual abuse perpetuated across successive generations. This…

Notes that existence of substantial correlation between two or more independent variables creates problems of multicollinearity in multiple regression. Discusses multicollinearity problem in social work research in which independent variables are usually intercorrelated. Clarifies problems created by multicollinearity, explains detection of…

Discusses several issues that pertain to analysis of data from repeated measurements designs. Notes that necessity for assumption concerning uniformity of correlations can be avoided by calculating linear and/or nonlinear trend scores. Discusses advantages of separately calculated trend scores. Proposes conservative criterion for use of one-sided…

Discusses problems researchers face when they want to describe relationship between several predictors and criterion variable. Considers ways of addressing problem of contribution of each predictor depending on which other predictors are in regression equation. Focuses on parallel information for each variable, examining initial and final…

This paper addresses a variation of the traditional validity question asked of qualitative researchers. Here the question is not "How do we know the qualitative researcher's question is valid?" but rather, "How does the qualitative researcher choose from among a multitude of apparently valid or at least plausible…

Many studies examining health service utilization by older adults involve secondary analyses of existing data sources and rely on behavioral model of health services utilization. Suggests that severe shortcomings in breadth and depth of available data, and numbers of intervals at which data have been recorded, limit understanding of health…

This poem, with stanzas in limerick form, refers humorously to the many threats to validity posed by problems in research design, including problems of sample selection, data collection, and data analysis. (SLD)

Some of the advantages of meta-analysis as a useful approach to synthesizing research studies are described, along with caveats that a careful analyst should consider when applying this approach to research data. (LC)

Presents general principles for cleaning data sets. Suggests techniques: check for column shifts, data completeness, marginal frequencies, and selected cross-tabulations; examines a sample of cases. Gives strategies for preventing data processing errors. (SK)
