The aim of this paper is to provide an introduction of new imputation algorithms for estimating missing values from official statistics in larger data sets of data pre-processing, or outliers. The goal is to propose a new algorithm called IRMI (iterative robust model-based imputation). This algorithm is able to deal with all challenges like…

Publication selection bias is a serious challenge to the integrity of all empirical sciences. We derive meta-regression approximations to reduce this bias. Our approach employs Taylor polynomial approximations to the conditional mean of a truncated distribution. A quadratic approximation without a linear term, precision-effect estimate with…

We examine how student attitudes toward their group, learning method, and perceived development of professional skills are initially shaped and subsequently evolve through multiple uses of team exams. Using a Tobit regression model to analyse a sequence of 10 team quizzes given in a graduate-level tax accounting course, we show that there is an…

Although the majority of colleges and universities are equipped with the latest instructional technologies, an appreciable integration of technology has not been observed in instructional practices (Flavin, 2013; Garrison & Akyol, 2009; Salinas, 2008). The purpose of this research is to understand the impact that generational differences can…

Although incremental creativity and radical creativity have been established as two distinct types of creativity, many questions remain about the antecedents and processes that result in these two types of creativity. This field study considered the impact of a motivational factor (creative self-efficacy), as well as factors that involve…

This study aims to determine the relationship between authenticity and subjective vitality among university students in Turkey. The study was carried out with 284 university students (164 female, 120 male, M[subscript age] = 19.91 years, SD = 1.79, and age range: 17-30). Participants completed the Turkish version of the Authenticity Scale and…

Integrating generic information about categories with knowledge of specific individuals is a critical component of successful inductive inferences. The present study tested whether children's approach to this task systematically shifts as they develop causal understandings of the mechanisms that shape individual action. In the current study, 3-and…

Purpose/Objectives: The purpose of this study was to explore school nutrition directors' attitudes and behaviors about food recalls. Specific objectives included: 1) Determine current food recall attitudes and the relationship between demographics and these attitudes; 2) Determine current practices of school nutrition directors related to…

To assess satisfactory job performance of superintendents on the basis of school districts' high-stakes testing outcomes, existing teacher models were reviewed and critiqued as potential options for retrofit. For these models, specific problems were identified relative to the choice of referent groups. An alternate referent group (statewide…

The purpose of this study is two-fold: to explore the differences in online medical information searching behaviors, including evaluative standards and search strategies, of the general public (general group) and those of hospital patients and their relatives (hospital group); and to compare the predictive relationship between the evaluative…

Low health literacy is associated with poor health outcomes. Research is needed to understand the mechanisms and pathways of its effects. Computer-based assessment tools may improve efficiency and cost-effectiveness of health literacy research. The objective of this preliminary study was to assess if administration of the Short Test of Functional…

This paper illustrates how a third statistic from asset pricing models, the R-squared statistic, may have information that can help in portfolio construction. Using a traditional CAPM model in comparison to an 18-factor Arbitrage Pricing Style Model, a portfolio separation test is conducted. Portfolio returns and risk metrics are compared using…

The use of propensity scores as a method to promote causality in studies that cannot use random assignment has increased dramatically since its original publication in 1983. While the utility of these approaches is important, the concepts underlying their use are complex. The purpose of this article is to provide a basic tutorial for conducting…

The existing literature presents conflicting models of how "this" and "that" access different segments of a written discourse, frequently relying on implicit analogies with spoken discourse. On the basis of this literature, we hypothesized that in written discourse, "this" more readily accesses the adjacent/right…

Purpose: This study investigated the etiology of late language emergence (LLE) in 24-month-old twins, considering possible twinning, zygosity, gender, and heritability effects for vocabulary and grammar phenotypes. Method: A population-based sample of 473 twin pairs participated. Multilevel modeling estimated means and variances of vocabulary and…
