title: Fraction Intervention for Fifth Graders Including Worked Examples and Multiple Representations

description: The current study investigated the effects of an intervention that combined the concrete-representational-abstract integrated sequence with worked problems with errors. Six fifth-grade students receiving tier three interventions within MTSS participated. The students learned fraction equivalence, the operations of addition and subtraction and fraction simplification. The intervention taught these skills with explicit instruction using fraction blocks, number lines, numbers, and symbols. The researchers also presented worked fraction equations with errors that mirrored the students’ error patterns; the students used fraction blocks to explain the error pattern and why it was not reasonable before correctly solving the equation. The researchers used a multiple probe across students single case research design and assessed both maintenance at two and four weeks after instruction. There was a functional relation between the intervention package and students’ computation of equations that included fractions with unlike denominators. The students maintained their skills up to four weeks after intervention.

title: Dataset for: Public Participation in China's State-Created ICT Spaces: Explaining Participation Patterns

description: t has become commonplace for non-democratic regimes to integrate information and communication technologies (ICTs) into their governance system. However, how citizens make use of these new digital opportunities in an authoritarian setting remains understudied. Based on an online survey in China in 2021, we find that a surprisingly large share of Chinese citizens engages with the new ICT-based participatory venues. But ICTs seem to unfold their potential only for certain groups such as tech-savvy younger citizens with a higher income. Moreover, while citizens seem to be quite aware of the risks of using ICTs, such as data security breaches or digital surveillance, these do not seem to hamper participation. Rather, citizens trade off perceived risks for perceived benefits, such as higher levels of convenience, efficiency, or expected government responsiveness. Our study contributes to the literature on digital governance in authoritarian regimes, and the digital divide and technology acceptance literatures. Moreover, amid the tightening of political control in China, it offers insights into participatory developments under Xi Jinping.

title: Constructing large orthogonal minimally aliased response surface designs by concatenating two definitive screening designs

description: Orthogonal minimally aliased response surface (OMARS) designs permit the study of quantitative factors at three levels using an economical number of runs. In these designs, the linear effects of the factors are neither aliased with each other nor with the quadratic effects and the two-factor interactions. Complete catalogs of OMARS designs with up to five factors have been obtained using an enumeration algorithm. However, the algorithm is computationally demanding for designs with many factors and runs. To overcome this issue, we propose a construction method for large OMARS designs that concatenates two definitive screening designs and improves the statistical features of its parent designs. The concatenation employs an algorithm that minimizes the aliasing among the second-order effects using foldover techniques and column permutations for one of the parent designs. We study the properties of the new OMARS designs and compare them with alternative designs in the literature.

title: Schema-based Instruction Additive and Multiplicative Compare

description: This study investigated the effects of schema-based instruction on students’ performance solving additive and multiplicative compare word problem types. Four students in the fifth grade participated; two had learning disabilities and two received tertiary services within a multi-tiered system of support. Students learned problem solving skills using graphic organizers representing problem types, a problem-solving checklist, and explicit instruction. The researchers used a single case research design, specifically a multiple probe across participants with embedded changing conditions. They assessed students’ use of problem-solving steps and accuracy as well as maintenance at two, four, and six weeks. There was a functional relation between schema-based instruction and students’ use of problem-solving steps as well as their accuracy which both improved. Students maintained their learning across six weeks.

title: Computational and Design of Experiment Strategies to Improve Differentiation and Quantitation of Trace-Level Cannabinoids by Copper Cationization Paper Spray Mass Spectrometry

description: The medicinal and recreational use of cannabis products is quickly rising from increased worldwide legalization and decriminalization. Despite this, current analytical methods have compromises when analyzing common isobaric cannabinoids, such as cannabidiol (CBD) or (−)-trans-Δ9-tetrahydrocannabinol (THC). We report on the use of computational chemistry, combined with design of experiment (DoE), to optimize and develop a paper spray mass spectrometry method with on-paper cationization to simplify workflow for trace level differentiation and quantitation of THC and CBD. Computational chemistry allowed for pre-screening of candidate metal ions prior to experimental measurements, with promising candidates then being evaluated by electrospray ionization high resolution mass spectrometry (ESI-HRMS). A direct mass spectrometry method using copper cationization with paper spray mass spectrometry (PS-MS) was then developed and optimized using DoE. Copper cationization with both ESI and PS-MS tandem mass spectrometry demonstrated the best CBD/THC selectivity and sensitivity, with ~1% interference between [CuCBD]+ and [CuTHC]+, allowing rapid direct mass spectrometry differentiation. DoE results increased the analytical performance of the PS-MS method for quantifying cannabinoids in methanol and saliva. Detection limits in methanol were 10 ng/mL for CBD and 20 ng/mL by PS-MS, whereas detection limits in saliva and acetonitrile/water matrices were &lt;2 ng/mL for both THC and CBD. This work illustrates the advantages of using DoE and computational chemistry to develop PS-MS and ESI methods that can differentiate and quantify isobaric cannabinoids.
