A Wikipedia powered state-based approach to automatic search query enhancement

This paper describes the development and testing of a novel Automatic Search Query Enhancement (ASQE) algorithm, the Wikipedia N Sub-state Algorithm (WNSSA), which utilises Wikipedia as the sole data source for prior knowledge. This algorithm is built upon the concept of iterative states and sub-states, harnessing the power of Wikipedia’s data set and link information to identify and utilise reoccurring terms to aid term selection and weighting during enhancement. This algorithm is designed to prevent query drift by making callbacks to the user’s original search intent by persisting the original query between internal states with additional selected enhancement terms. The developed algorithm has shown to improve both short and long queries by providing a better understanding of the query and available data. The proposed algorithm was compared against five existing ASQE algorithms that utilise Wikipedia as the sole data source, showing an average Mean Average Precision (MAP) improvement of 0.273 over the tested existing ASQE algorithms.     

Re‐examining format distortion and orthographic neighbourhood size effects in the left,central and right visual fields

Research has shown orthographic neighbourhood size effects (ONS) in the left visual field (LVF) but not in the right visual field (RVF). An earlier study examined the combined effects of ONS and font distortion in the LVF and RVF, but did not find an interaction. The current lexical decision experiment re‐examined the interaction between ONS and format distortion at fixation and in the LVF and RVF with the addition of several methodological improvements. Main results replicated previous findings and extended them by indicating that (a) ONS effects in the LVF are immune to the putatively disruptive effects of format distortion, (b) format distortion revealed ONS effects in the RVF and (c) large orthographic neighbourhood size slowed pseudoword rejections regardless of format distortion or visual field presentation. Results are discussed within the context of relevant literature on the visual field laterality of visuoperceptual‐orthographic processing.     

Bridging the Digital and the Physical User Experience: Analysis of Academic Library Floor Plans

Abstract

In library user experience (UX) literature, physical and digital spaces are often studied separately. In academic libraries, different stakeholders often control and operate the logistics of each set of spaces. Additionally, library UX studies seldom consider the physical experiences of users beyond the borders of library websites or buildings. Our survey of 37?U.S. academic library websites found that 97% had some kind of digital representations of physical spaces – predominantly floor plans. A content analysis of those floor plans found that many were poorly designed, and identified two specific themes: non-accessible content and a lack of comprehensive information to facilitate the user journey. This paper offers several recommendations for building more accessible digital representations of physical spaces for the library website. These trends and recommendations are intended to be instructive for managers of library websites and elucidate larger themes about academic libraries.     

Parents’ reading-related knowledge and children’s reading acquisition

Teacher reading-related knowledge (phonological awareness and phonics knowledge) predicts student reading, however little is known about the reading-related knowledge of parents. Participants comprised 70 dyads (children from kindergarten and grade 1 and their parents). Parents were administered a questionnaire tapping into reading-related knowledge, print exposure, storybook reading, and general cultural knowledge. Children were tested on measures of letter-word knowledge, sound awareness, receptive vocabulary, oral expression, and mathematical skill. Parent reading-related knowledge showed significant positive links with child letter-word knowledge and sound awareness, but showed no correlations with child measures of mathematical skill or vocabulary. Furthermore, parent reading-related knowledge was not associated with parents' own print exposure or cultural knowledge, indicating that knowledge about English word structure may be separate from other cognitive skills. Implications are discussed in terms of improving parent reading-related knowledge to promote child literacy.     

Executive impairment determines ADHD medication response: implications for academic achievement

Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to indirect informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes direct neuropsychological or academic assessment data to determine treatment efficacy. Documenting "cool" executive-working memory (EWM) and "hot" self-regulation (SR) neuropsychological impairments could aid in differential diagnosis of ADHD subtypes and determining cognitive and academic MPH response. In this study, children aged 6 to 16 with ADHD inattentive type (IT; n = 19) and combined type (n = 33)/hyperactive-impulsive type (n = 4) (CT) participated in double-blind placebo-controlled MPH trials with baseline and randomized placebo, low MPH dose, and high MPH dose conditions. EWM/ SR measures and behavior ratings/classroom observations were rank ordered separately across conditions, with nonparametric randomization tests conducted to determine individual MPH response. Participants were subsequently grouped according to their level of cool EWM and hot SR circuit dysfunction. Robust cognitive and behavioral MPH response was achieved for children with significant baseline EWM/SR impairment, yet response was poor for those with adequate EWM/ SR baseline performance. Even for strong MPH responders, the best dose for neuropsychological functioning was typically lower than the best dose for behavior. Findings offer one possible explanation for why long-term academic MPH treatment gains in ADHD have not been realized. Implications for academic achievement and medication titration practices for children with behaviorally diagnosed ADHD will be discussed.     

On creating a workable signing environment: deaf and hearing perspectives

This article studies teams of service providers in education and psychiatric services, in which a substantial number of both deaf and hearing people work together as colleagues. It focuses specifically on the challenges involved in cooperatively creating a signing work environment. Using a methodology that draws on the principles of ethnography, it identifies and explores the meaning constructions associated with signing at work, from deaf and hearing perspectives. Data were collected through interviews in three organizations all in the United Kingdom: two specialist psychiatric units for deaf adults and a school for deaf children. Forty-one informants participated (20 deaf, 21 hearing). Results show that from a deaf perspective, hearing people's use of sign language in their presence at work is closely associated with demonstrating personal respect, value, and confidence, and hearing colleagues' willingness to sign is more significant than their fluency. From a hearing perspective, results demonstrate that sign language use at work is closely associated with change, pressure, and the questioning of professional competence. The challenges involved in improving deaf/hearing relations are perceived from a deaf perspective as largely person-centered, and from a hearing perspective as primarily language-centered. The significance of organizational factors such as imbalances in power and status between deaf and hearing colleagues is explored in relation to the findings.
