Political scientists have long studied the use of direct democratic ballot initiatives—proposed directly by citizens and put before a statewide vote—as currently allowed in 24 U.S. states. Despite ...the application of ballot initiatives to legislate education policy, however, education scholars have not yet adequately investigated this phenomenon within American public education. In a comprehensive analysis of state-level direct democracy in education, this article examines the content and prevalence of education ballot initiatives used to shaped U.S. education policy over time. Analyses suggest voters have considered 282 ballot initiatives regarding a variety of education issues, including those related to both K-12 and higher education and addressing policy issues related to finance, governance, and civil rights and equal opportunity. Further, the prevalence of education initiatives has increased and their content has evolved over time, particularly with the advent of, and increase in, initiatives seeking to limit the rights and opportunities of traditionally underrepresented students. These findings contribute to scholarship regarding state-level education policymaking in general, and call on researchers to consider further the benefits and potentially negative consequences of direct democracy as an education policymaking tool, particularly for minoritized students.
Abstract
The use of research evidence (URE) in policy and practice is relevant to many academic disciplines, as well as policy and practice domains. Although there has been increased attention to how ...such evidence is used, those engaged in scholarship and practice in this area face challenges in advancing the field. This paper attempts to “map the field” with the objective of provoking conversation about where we are and what we need to move forward. Utilizing survey data from scholars, practitioners, and funders connected to the study of the use of research evidence, we explore the extent to which URE work span traditional boundaries of research, practice, and policy, of different practice/policy fields, and of different disciplines. Descriptive and network analyses point to the boundary spanning and multidisciplinarity of this community, but also suggest exclusivity, as well as fragmentation among disciplines and literatures on which this work builds. We conclude with opportunities for to improve the connectedness, inclusiveness, relationship to policy and practice, and sustainability of URE scholarship.

We present a combined theoretical and experimental study of the ferromagnetic semiconductor (Ga,Mn)As which explains the remarkably large changes observed on low-temperature annealing. Careful ...control of the annealing conditions allows us to obtain samples with ferromagnetic transition temperatures up to 159 K. Ab initio calculations, in situ Auger spectroscopy, and resistivity measurements during annealing show that the observed changes are due to out diffusion of Mn interstitials towards the surface, governed by an energy barrier of 0.7-0.8 eV. Electric fields induced by Mn acceptors have a significant effect on the diffusion.
Overcrowding in emergency departments (ED) is a major concern worldwide. To answer increasing health care demands, new models of care including advanced practice physiotherapists (APP) have been ...implemented in EDs. The purpose of this study was to assess diagnostic, treatment and discharge plan concordance between APPs and ED physicians for patients consulting to the ED for minor musculoskeletal disorders (MSKD).
Patients presenting to two EDs in Montréal (Canada) with a minor MSKD were recruited and independently assessed by an APP and ED physician. Both providers had to formulate diagnosis, treatment and discharge plans. Cohen's kappa (κ) and Prevalence and Bias Adjusted Kappas (PABAK) with associated 95%CI were calculated. Chi Square and t-tests were used to compare treatment, discharge plan modalities and patient satisfaction between providers.
One hundred and thirteen participants were recruited, mean age was 50.3 ± 17.4 years old and 51.3% had an atraumatic MSKD. Diagnostic inter-rater agreement between providers was very good (κ = 0.81; 95% CI: 0.72-0.90). In terms of treatment plan, APPs referred significantly more participants to physiotherapy care than ED physicians (κ = 0.27; PABAK = 0.27; 95% CI: 0.07-0.45; p = 0.003). There was a moderate inter-rater agreement (κ = 0.46; PABAK = 0.64; 95% CI: 0.46-0.77) for discharge plans. High patient satisfaction was reported with no significant differences between providers (p = 0.57).
There was significant agreement between APPs and ED physicians in terms of diagnosis and discharge plans, but more discrepancies regarding treatment plans. These results tend to support the integration of APPs in ED settings, but further prospective evaluation of the efficiency of these types of models is warranted.
