Reporting Quality of Single-Case Research Published in Learning Disabilities Journals

Single-case research designs are useful for learning disability researchers interested in refining novel interventions (e.g., new mathematics intervention) before scaling, small n populations (e.g., students with comorbid learning and emotional and behavioral disabilities), and testing unique conditions (e.g., remote locales). Much attention has been devoted to developing research quality standards, which is essential for replication and implementation fidelity; however, little is known about the reporting quality of single-case design studies. To gain insight into the quality of learning disability single-case research design study reporting, we analyzed 72 articles published between 2010 and 2021 in six learning disability-focused journals using the Single-Case Reporting Guideline In BEhavioral interventions (SCRIBE) standards. Findings suggest that reporting quality has remained stagnant, and none of the studies reviewed met all of the reporting standards. Alignment with standards ranged from 33% to 77%. Implications for researchers and practitioners are discussed.     

TRAINING POLICY GERONTOLOGISTS: AN EXPLORATORY STUDY OF NEEDED SKILLS,KNOWLEDGE, AND ATTRIBUTES

Findings from a survey of policy professionals in aging (n = 114) and experience with a demonstration program to train policy gerontologists indicates that (1) the demand for policy gerontologists is moderately high; (2) training requirements include specific skills training in political processes, communication, analysis, and administration; (3) policy gerontologists require such personal attributes as follow through, initiative, and innovation; and (4) knowledge of the content of specific policy areas as well as an understanding of the policy‐making process is important. Findings have been used to develop a model curriculum for training policy gerontologists which is presented and discussed.     

English Language Learners and Learning Disabilities: Research Agenda and Implications for Practice

Although little is known about learning disabilities (LDs) in English language learners (ELLs), there is a substantial knowledge base about the identification, assessment, and intervention of and for LDs in monolingual native English‐speaking students. Building on this knowledge, participants at an October 2003 National Symposium on Learning Disabilities in English Language Learners were asked to suggest research questions, priorities, and suggestions on how to build the necessary infrastructure to address critical research needs. In the discussions that took place, important themes emerged: (1) identification and assessment of LD and/or reading disabilities (RD) in ELLs (ELL/Ds), (2) understanding of the language and literacy developmental trajectories of ELLs, (3) understanding of the individual and contextual factors affecting outcomes, (4) the intersection of all of these areas with neurobiology, and (5) developing and testing the effectiveness of interventions for learning disabilities in ELL/Ds. These themes, and the research agenda that was forged around them, are presented. In addition, the practice implications of this agenda are presented, along with some suggestions for current practice while we await future research findings.     

Academic attitudes toward new media: An exploratory multidisciplinary study

This article looks at the attitudes of UK academics toward new media, utilizing organizational and sociocultural understandings of fields of scholarly enquiry. It focuses on four traditionally distinct disciplines—art and design, computer science, health science, and politics and international relations—representative of the range of approaches in higher education. Agreement was found among respondents across disciplinary communities about what new media represent and how they support their work. Analysis of semantic differential charts identified two dimensions underlying attitudes—“flexibility” and “fitness for scholarly purposes.” Rather than being anchored by epistemological divisions, new media are assessed by practical viewpoints relating to the activity types they allow, and by traditional measures of reliability. In response to questions about other characteristics of their disciplines (such as reputation and audience diversity), distinctions are in evidence, although in some cases these are not traditional ones.     

On recursive averaging processes and Hilbert space extensions of the contraction mapping principle

If T maps a convex domain D_T into itself, and if {ω_n} is a real sequence with range in (0, 1] then the recursive averaging process,

$\text{X}{}_{\mathrm{n+1}}\text{=(1?omega;}{}_{\mathrm{n}}\text{)}\text{X}{}_{\mathrm{n}}\text{+ω}{}_{\mathrm{n}}\text{+ω}{}_{\mathrm{n}}\text{T}\text{x}{}_{\mathrm{n}}\text{,}\text{x}{}_0\text{=ξ?D}{}_{\mathrm{T}}$

generates a sequence {x?_n}; with range in D_T. Under suitable conditions on D_T, T and {ω_n} the sequence {x?_n} will converge in some sense to a fixed point of T. We prove that if D_T is a closed convex subset of a complex Hilbert space H, if Tω = (1 ? ω) I + ωT is a strict contraction for some ω ? (0, 1], and if {ω_n} satisfies the conditions,

$\text{ω}{}_{\mathrm{n}}\text{→ 0}$

and

$\text{∑}\text{n=0}\text{∞}\text{ω}{}_{\mathrm{n}}\text{=∞}$

then, for arbitrary ξ ? D_T, {x?_n} converges strongly to (the unique) fixed point of T. We also prove that if D_T and {ω_n} satisfy the foregoing conditions, if T has at least one fixed point, and if Tω is non-expansive for some ω ? (0, 1], then for all ξ ? D_T, {x?_n} converges at least weakly to some fixed point of T. Finally, we apply these results to linear equations involving bounded normal operators and obtain an extension of the classical Neumann operator series.     

Wonderful secrets of nature. Natural knowledge and religious piety in Reformation Germany

Sixteenth-century Germany witnessed a tremendous flourishing of vernacular literature. An unprecedented number and variety of texts were produced for new groups of readers. This essay analyzes one underexplored genre of this vernacular literature: texts on the natural world. Numerous books on animals, plants, minerals, and natural marvels rolled off the German presses in this period, indicating a widespread curiosity about the natural world. These texts give valuable insight into the views of nature available to a broad lay audience, literate in German but not necessarily in Latin. They reveal a pervasive sense of nature as divinely created and a deep conviction that contemplation of the natural world would lead to greater piety. The divine and the mundane were thoroughly intertwined in vernacular natural histories. While other historians of science have seen the sixteenth century as a period of increasingly secular ways of thinking about nature, I argue for the persistence, and even the intensification, of profoundly religious attitudes toward the natural world.
