Adjacent category logit models are ordered regression models that focus on comparisons of adjacent categories. These models are particularly useful for ordinal response variables with categories that are of substantive interest. In this article, we consider unconstrained and constrained versions of the partial adjacent category logit model, which…

The term "polyfunctionality" has an extraordinary number of synonyms and near-synonyms in linguistics, e.g. "multifunctionality," "polycategoriality," "conversion," and "zero derivation." In this paper I will present many of these terms and discuss possible differences (for some authors) among…

Social innovations (SIs) frequently bring previously unrelated actors, ideas, and practices together in new configurations with the goal of addressing social needs. However, the dizzying variety of definitions of SI and their dynamic, exploratory character raise dilemmas for evaluators tasked with their evaluations. This article is based on a…

Analyzing relationships of necessity is important for both scholarly and applied research questions in the social sciences. An often-used technique for identifying such relationships--"fuzzy set Qualitative Comparative Analysis" (fsQCA)--has limited ability to make the most out of the data used. The set-theoretical technique fsQCA makes…

Recent research studies have shown that increased letter spacing has a positive effect on the reading ability of dyslexic individuals. This study aims to investigate the effect of spacing on the readability of different fonts for children with and without dyslexia. Results did not support the hypothesis of better performance among children with…

Mentoring, coaching, and advising are often confused as similar interactions with developmental intent, yet their scope, purpose, and utility in leadership development are distinct. The purpose of this chapter is to provide clarity as to what constitutes mentoring, coaching, and advising for leadership development and to compare and contrast each…

This essay examines comparison in a double sense. Focusing on ethnographies of teachers' work in the published literature, I ask whether it is possible to compare ethnographic studies across national borders without losing the particularities of local context, and also without losing the distinctive theoretical perspective of ethnographers…

This paper concerns an investigation of the manner in which typicality constrains graded membership in antonymous dimensional adjectives such as "short/tall" and "cheap/expensive" using the conceptual spaces framework. In this framework, items are organized in a space comprised of one or more dimensions along which they can be…

In education research, conceptual models are becoming more complex and more challenging to fit. In response, many researchers have turned to multi-step model fitting processes; first fitting confirmatory factor analyses (CFA) to their data, then extracting the latent factor scores; converting them to observed variables to use in additional…

The research landscape displays increasing awareness of the important role of self-regulation and emotions in the process of acquiring Collaborative Problem-Solving skills (CPS), which are considered essential in almost all areas of life. However, there is still a dearth of research on developing CPS skills among elementary-school students. Our…

The Schwarz or Bayesian information criterion (BIC) is one of the most widely used tools for model comparison in social science research. The BIC, however, is not suitable for evaluating models with order constraints on the parameters of interest. This article explores two extensions of the BIC for evaluating order-constrained models, one where a…

This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and…

Background: Performance monitoring plays a key role in self-regulated learning, but is difficult, especially for complex visual tasks such as navigational map reading. Gaze displays (i.e. visualizations of participants' eye movements during a task) might serve as feedback to improve students' performance monitoring. Objectives: We hypothesized…

The utility of three-dimensional (3D) printed models for medical education in complex congenital heart disease (CHD) is sparse and limited. The purpose of this study was to evaluate the utility of 3D printed models for medical education in criss-cross hearts covering a wide range of participants with different levels of knowledge and experience,…

Morphological awareness, or sensitivity to units of meaning, is an essential component of reading comprehension development. Current neurobiological models of reading and dyslexia have largely been built upon phonological processing models, yet reading for meaning is as essential as reading for sound. To fill this gap, the present study explores…
