Significant Divergence

The studies of post-communist Russia and China have traditionally been dominated by single-case studies and within-region comparisons. This chapter explores why the CAS of post-communist Russia and China is difficult, why it is rare, and how it could yield significant and unique intellectual payoffs. The cross-regional comparative study of anti-corruption campaigns in contemporary Russia and China is used as an example in this chapter to argue that a well-matched and context-sensitive comparison could reveal significant divergence in the elite politics and institutional capacities of these regimes that would otherwise likely be obscured by single-case studies or studies restricted to one single geographical area such as “Eastern Europe” or “East Asia.” By breaking Russia and China out of their respective “regions,” the CAS perspective thus enables us to better capture the full range of existing diversity of post-communist authoritarianism.

The Impact

In this meta-analytic review, we investigated the effects of technology supports on the acquisition of shopping skills for students with intellectual and developmental disabilities (IDD) between the ages of 5 and 24. Nineteen single-case experimental research studies, presented in 15 research articles, met the current study’s inclusion criteria and the What Works Clearinghouse (WWC) standards. An analysis of potential moderators was conducted, and we calculated effect sizes using Tau-U to examine the impact of age, diagnosis, and type of technology on the reported outcomes for the 56 participants. The results from the included studies provide evidence that a wide range of technology interventions had a positive impact on shopping performance. These positive effects were seen for individuals across a wide range of ages and disability types, and for a wide variety of shopping skills. The strongest effect sizes were observed for technologies that provided visual supports rather than just auditory support. We provide an interpretation of the findings, implications of the results, and recommended areas for future research.

The Comparative Study

This article considers the role of generalization in comparative case studies, using as exemplars the contributions to this special issue on climate change politics. As a research practice, generalization is a logical argument for extending one’s claims beyond the data, positing a connection between events that were studied and those that were not. No methodological tradition is exempt from the requirement to demonstrate a compelling logic of generalization. The article presents a taxonomy of the logics of generalization underlying diverse research methodologies, which often go unstated and unexamined. I introduce the concept of resonance groups, which provide a causeway for cross-system generalization from single case studies. Overall the results suggest that in the comparative study of complex political systems, case study research is, ceteris paribus, on par with large-N research with respect to generalizability.

Social Upgrading

This book addresses the controversies surrounding smallholders’ opportunities for economic and social upgrading by joining global agricultural value chains (AVC). While international organizations encourage small farmers to become part of AVC, critics point out its risks. Unlike previous single case studies, researchers from three continents compared the influence of the characteristics of the crop (coffee, mango, rice), the end markets, and the national political economic contexts on the social and economic conditions for smallholders and agricultural workers. Their findings highlight the importance of collective action by smallholders and of a supportive state for economic and social upgrading.

Children With Developmental Disabilities

Purpose Shared interactive book reading (SIBR) is an evidence-based practice for young children who are typically developing and those with developmental disabilities or considered at risk for developmental delays. The purpose of this review was to provide a comprehensive examination of the evidence of using SIBR to facilitate growth in language skills for young children with developmental disabilities and/or delays. Specifically, authors examined the descriptive characteristics, study rigor, and effect sizes for language and literacy outcomes. Method We extracted data from studies meeting specified criteria ( n = 23) published in peer-reviewed journals on a wide range of variables, including participant characteristics, setting, training/coaching, defined independent and dependent variables, study rigor, and overall outcomes. Descriptive and study rigor data were aggregated using descriptive statistics. Effect-size estimates were calculated for all child outcomes related to language. Results Descriptive data were variable across studies. Three single-case experimental design and three group design studies met design standards without reservations. Single-case experimental design studies overall showed positive effects on child language and communication. Within group design studies, expressive language outcomes showed the largest effect sizes. Conclusion A review of SIBR studies indicates this as a viable intervention to positively impact the language skills of young children with developmental disabilities and/or delays.
