Manjula Wijewickrema – portal: Libraries and the Academy, 2024
This research compares the performance measures reported by two bibliographic databases relevant to a set of authors who have published in predatory journals. The reliability of decision-making based on the information provided by uncontrolled bibliographic databases is examined to support rational decisions. A sample of authors who published in…

Christoph Niessen – Sociological Methods & Research, 2024
In the wake of the methodological developments that aim to render qualitative comparative analysis (QCA) "time sensitive", I propose a new procedure for carrying out QCA longitudinally. More specifically, I show first why longitudinal case disaggregation should be carried out with change-based intervals (CBIs) rather than with fixed…

Robert Hepach; Michael Tomasello – Child Development Perspectives, 2025
Chimpanzees and other great apes seem to be much less cooperative than humans overall, yet they nevertheless reliably help others in many instrumental circumstances. Although in many contexts the helping behavior of chimpanzees is quite similar to that of human children, recent studies using both behavioral and psychophysiological paradigms have…

Michael C. Robbins; Zhuping Li – Field Methods, 2025
The Nolan Index (NI) is a normed, quantitative measure for comparing the degree of resemblance (similarity or dissimilarity) between free listings with an Excel program for calculating it. This article enhances that effort with the addition of an R program and additional applications. Free-list resemblance measures have been used to investigate…

Skinner, Christopher H.; Fowler, Kristen; Cates, Gary L.; Poncy, Brain; Duhon, Gary J.; Solomon, Benjamin G.; Belfiore, Phillip J. – Psychology in the Schools, 2023
Measures of learning speed (i.e., the amount of learning/cumulative time learner spends engaged in an intervention) are rarely included in research designed to evaluate and compare academic interventions. We build a case that includes analyses of learning speed metrics in academic intervention research can provide more useful information for…

Truong, Bang; Tran, Lan-Anh T.; Le, Tuan Anh; Pham, Thi Thu; Vo, Tat-Thang – Research Synthesis Methods, 2023
In health technology assessment (HTA), population-adjusted indirect comparisons (PAICs) are increasingly considered to adjust for the difference in the target population between studies. We aim to assess the conduct and reporting of PAICs in recent HTA practice, by performing, a methodological systematic review of studies implementing PAICs from…

Rutten, Roel – Sociological Methods & Research, 2023
Uncertainty undermines causal claims; however, the nature of causal claims decides what counts as relevant uncertainty. Empirical robustness is imperative in regularity theories of causality. Regularity theory features strongly in QCA, making its case sensitivity a weakness. Following qualitative comparative analysis (QCA) founder Charles Ragin's…

Davis, William S.; Liu, Bo; Kim, Josephine – Foreign Language Annals, 2023
Given the ongoing shortage of world language teachers in the United States, growing attention has developed toward recruiting new teachers at the secondary and postsecondary levels. This mixed methods study examined why some university noneducation students involved in language study at a large public institution indicated they would consider…

Leala Holcomb; Wyatte C. Hall; Stephanie J. Gardiner-Walsh; Jessica Scott – Journal of Deaf Studies and Deaf Education, 2025
This study critically examines the biases and methodological shortcomings in studies comparing deaf and hearing populations, demonstrating their implications for both the reliability and ethics of research in deaf education. Upon reviewing the 20 most-cited deaf-hearing comparison studies, we identified recurring fallacies such as the presumption…

Markus Gangl – Sociological Methods & Research, 2025
Rating scales are ubiquitous in the social sciences, yet may present practical difficulties when response formats change over time or vary across surveys. To allow researchers to pool rating data across alternative question formats, the article provides a generalization of the ordered logit model that accommodates multiple scale formats in the…

Sohee Kim; Ki Lynn Cole – International Journal of Testing, 2025
This study conducted a comprehensive comparison of Item Response Theory (IRT) linking methods applied to a bifactor model, examining their performance on both multiple choice (MC) and mixed format tests within the common item nonequivalent group design framework. Four distinct multidimensional IRT linking approaches were explored, consisting of…

Bruno Arpino; Silvia Bacci; Leonardo Grilli; Raffaele Guetto; Carla Rampichini – Evaluation Review, 2025
We consider estimating the effect of a treatment on a given outcome measured on subjects tested both before and after treatment assignment in observational studies. A vast literature compares the competing approaches of modelling the post-test score conditionally on the pre-test score versus modelling the difference, namely, the gain score. Our…

Liyang Sun; Eli Ben-Michael; Avi Feller – Grantee Submission, 2024
The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit with panel data. Two challenges arise with higher frequency data (e.g., monthly versus yearly): (1) achieving excellent pre-treatment fit is typically more challenging; and (2) overfitting to noise is more likely. Aggregating data…

Julien Kloeg; Liesbeth Noordegraaf-Eelens – Educational Theory, 2024
A key aspect of the educator's responsibility as understood by Hannah Arendt is its dual character. Educators are responsible for both the life and development of the child and the continuance of the world, as Arendt puts it in "The Crisis in Education." Moreover, these aspects of responsibility are in tension with each other. Arendt's…

Sohair Salem; Engy Ashaat – Journal of Autism and Developmental Disorders, 2024
Autism is associated with genomic instability, which is regulated by telomere length (TL) and index of global methylation (LINE-1). This study will determine relative TL (RTL) and LINE-1 methylation percentage for 69 patients and 33 control subjects to evaluate their potential role as biomarkers for autism. The results displayed a significant…
