Orthographic knowledge is one of several contributors to developing literacy skills. However, our understanding of how orthographic knowledge contributes to both spelling and reading is incomplete due to a lack of consistency in defining and measuring orthographic knowledge. The goal of the present study was to empirically test whether or not…

Questions concerning mediated causal effects are of great interest in psychology, cognitive science, medicine, social science, public health, and many other disciplines. For instance, about 60% of recent papers published in leading journals in social psychology contain at least one mediation test (Rucker, Preacher, Tormala, & Petty, 2011).…

Ranking systems such as "The Times Higher Education's World University Rankings" and Shanghai Jiao Tong University's "Academic Rankings of World Universities" simultaneously mark global status and stimulate global academic competition. As international ranking systems have become more prominent, researchers have begun to examine whether global…

With the development of PC, internet as well as mobile devices, we are facing a data exploding era. On one hand, more and more features can be collected to describe the data, making the size of the data descriptor larger and larger. On the other hand, the number of data itself explodes and can be collected from multiple resources. When the data…

We address the broader conceptual and pedagogical implications of recent recommendations of the International Union of Pure and Applied Chemistry (IUPAC) concerning the re-definition of hydrogen bonding, drawing upon the recommended IUPAC statistical methodology of mutually correlated experimental and theoretical descriptors to operationally…

This commentary to the recent article by Musso et al. (2013) discusses issues related to model fitting, comparison of classification accuracy of generative and discriminative models, and two (or more) cultures of data modeling. We start by questioning the extremely high classification accuracy with an empirical data from a complex domain. There is…

This article explores the use of longitudinal regression as a tool for identifying scoring inaccuracies. Student progression patterns, as evaluated through longitudinal regressions, typically are more stable from year to year than are scale score distributions and statistics, which require representative samples to conduct credibility checks.…

This study provides an empirical test of the assumption that the credibility of the messenger is one of the factors that influence knowledge mobilisation among policy makers. This general hypothesis was tested using a database of 321 social scientists from the province of Quebec that combines survey and bibliometric data. A regression model was…

Birth Preparedness and Complication Readiness (BP/CR) program has been promoted in Nepal to equip pregnant women with obstetric knowledge so as to motivate them to seek professional care. Using a prospective design of 701 pregnant women of more than 5 months gestation in a central hills district of Nepal, we evaluated if having obstetric knowledge…

The primary purpose of this investigation was to evaluate the relationship of handwriting speed, fine motor fluency, speed of verbal access, language comprehension, working memory, and attention (executive control; selective) to note-taking and all of the aforementioned variables to test performance (written recall). A second purpose was to…

The purpose of this paper is to provide an easy template for the inclusion of the Bayes factor in reporting experimental results, particularly as a recommendation for articles in the "Journal of Problem Solving." The Bayes factor provides information with a similar purpose to the "p"-value--to allow the researcher to make…

Purpose: The purpose of this study was to examine the association between objectively measured physical activity and hearing sensitivity among a nationally representative sample of U.S. adults with diabetes. Method: Data from the 2003-2006 National Health and Nutrition Examination Survey were used. One hundred eighty-four U.S. adults with diabetes…

This study investigates the joint effects of financial education and educational networks on students' financial literacy. With a sample (N = 105) of senior students in a business college, the study finds that not only financial education, but also strong networks with professors, are positively related to the financial literacy of business…

This study investigates the effects of background knowledge on Chinese word processing during silent reading by monitoring adult readers' eye movements. Both higher knowledge (physics major) and lower knowledge (nonphysics major) graduate students were given physics texts to read. Higher knowledge readers spent less time rereading and had…

Approaches to determining direction of dependence in nonexperimental data are based on the relation between higher-than second-order moments on one side and correlation and regression models on the other. These approaches have experienced rapid development and are being applied in contexts such as research on partner violence, attention deficit…
