Explicating Literacy Activities at Work: The use of ‘okay’ as an effective topic-changing device in service request calls
Authors: Kelly Ann 
Published: October 2014

There is evidence from different spheres that the grounding of understandings of literacy within social practices has gradually become accepted within the adult literacy field in Australia. However, what has been not been sufficiently considered are those tacit literacies that underpin such practices in both everyday and work settings. This has been the case particularly for those literacies that are deployed through an oral communication mode in workplaces. This article offers a way of explicating such literacies by showing how the analysis of an audio-recording of a particular occupational activity, namely the reporting of a service request, can render visible particular key literacy features. In this case, such an analysis shows how the marker ‘okay’ is used in a critical way to close off segments of an interaction and to mark verbally that agreement about a particular aspect of the request has been reached. It is argued that the use of recordings, both audio and video, for the purpose of highlighting tacit competencies has implications not only for adult literacy teachers but for trainers, assessors and curriculum developers within the broader vocational education and training sector.

Published: October 2014

The education of young people who have previously been excluded from formal education is a field often associated with a high risk of failure – failure for the learners, teachers and the program. In researching the teaching practices in this field, it is tempting for the researcher to do so through the lens of what they perceive as the pedagogical theories that should be informing contemporary practice. In the field of literacy and numeracy education, the social practices approach has gained prominence among researchers who are sympathetic to a socio-cultural study of literacy and numeracy because of its inclusiveness of multiple literacies and numeracies that can be found in different social contexts. This article analyses one of four case studies in a research project on the teaching practices of experienced literacy and numeracy teachers: teaching literacy and numeracy to socially excluded young people in an inner city youth centre. In their research, the authors had to critically challenge their taken for granted assumptions about what a pedagogy informed by a social practices approach to literacy and numeracy should look like. The teaching methods that they observed at the youth centre, while clearly effective – particularly in establishing connections with the learners to form strong relationships of mutual trust - appeared on the surface to defy some of the key features of a social practices approach. In understanding the apparent contradictions between what the authors had expected to see and what they were seeing, Kemmis’s framework for the study of practice that is based on the notion of practices as reflexive and dialectical proved fruitful. The framework allowed us to interpret both the theory (the social practices approach to literacy and numeracy) and the practices at the youth centre in more nuanced ways that deepened our appreciation of the theory – practice relationship.

Published: October 2014

Background: Studies have shown the positive effects of multidisciplinary rehabilitation on disability and health-related quality of life in multiple sclerosis (MS). However, many patients do not seek such treatment, even if it is available free of charge. The aim of this study was to identify facilitators and barriers related to use of such treatment options.Methods: Five focus group interviews with 27 MS patients were conducted. Three groups included patients who had been admitted to a multidisciplinary MS rehabilitation institution, and two groups included outpatients of a university hospital who had not applied for specialized rehabilitation. Interviews were audiotaped and transcribed, and were analyzed qualitatively by means of a modified form of systematic text condensation.Results: Important factors influencing the use of an MS rehabilitation service were 1) the availability and suitability of initial information about the disease and the service, 2) assumptions and expectations about such a service, and 3) practical barriers in the patient's life. The prospect of having a retreat from work and family was described as a motivational factor. Lack of reorientation after diagnosis, fears and perceptions of being labeled as an MS patient, or having information overload and being confronted with disabled individuals were identified as barriers.Conclusions: Communication skills, including information-giving skills, of neurologists in relation to newly diagnosed MS patients need improvement. Rehabilitation programs for MS patients should include stays of different durations and purposes to fit patients' needs. Health-care authorities should take measures to secure equal access to information about rehabilitation options across institutions and practicing physicians.
Impact of Proactive Case Management by Multiple Sclerosis Specialist Nurses on Use of Unscheduled Care and Emergency Presentation in Multiple Sclerosis
Authors: Leary Alison , Quinn Debbie , Bowen Amy 
Published: October 2014

Background: Multiple sclerosis (MS) affects approximately 100,000 people in the United Kingdom, with rising emergency admissions to the hospital. The multiple sclerosis specialist nurse plays a pivotal role in managing MS care in the United Kingdom, and there is anecdotal evidence that this role can help avoid emergency presentations and unnecessary hospital admissions.
Methods: A retrospective service evaluation took place in one established MS nursing service. The impact of the introduction of proactive nurse-led management and a rapid response service on rates of emergency presentation, hospital admission, and bed use was examined. The primary intervention was the introduction of extra nursing hours (6 hours per week) and the reallocation of some routine administrative duties, which allowed the service to move to a proactive management model aimed at avoiding the need for unplanned care. In addition, a care pathway was implemented in the emergency department for patients with MS who did present.
Results: Reduction in utilization was from a mean of 2700 bed-days per year (2002–2006) to a mean of 198 bed-days per year (2007–2013).
Conclusions: During a 10-year period, moving from reactive management to proactive management demonstrated an increase in complex specialist nursing interventions and led to a decrease in emergency presentation and bed use at the local acute-care center.

ImportanceDespite growing interest in the phenomenology of delusions in psychosis, at present little is known about their content and evolution over time, including whether delusion themes are consistent across episodes.ObjectiveTo examine the course of delusions and thematic delusion content across relapse episodes in patients presenting to an early intervention service for psychosis.Design, Setting, and ParticipantsThis longitudinal, observational study used clinical data systematically collected from January 2003 to March 2018 from a cohort of consenting patients with affective or nonaffective first-episode psychosis, followed up naturalistically for up to 2 years in an early intervention service for psychosis in Montréal, Quebec, Canada. Data included the thematic content and severity of delusions (scores ≥3 using the Scale for the Assessment of Positive Symptoms) and associated psychotic and nonpsychotic symptoms, both across an initial episode and, in the event of remission, a potential relapse. Data were analyzed from September 2021 to February 2023.ExposureAn early intervention service for psychosis, organized around intensive case management and a multidisciplinary team approach, which observed each patient for up to 2 years of care.Main Outcomes and MeasuresThe primary outcome was positive symptom relapse and remission, including the presence and content of delusions, which was coded per the Scale for the Assessment of Positive Symptoms and accepted definitions. The main statistical measures included repeated paired-sample t tests and binary logistic regression analyses.ResultsOf 636 consenting patients, mean (SD) age was 23.8 (4.75) years; 191 patients were female, 444 were male, and 1 patient was nonbinary. Remission rates were high, and relapse rates were relatively low: 591 individuals had baseline delusions, of which 558 (94.4%) achieved remission. Of these 558 patients, only 182 (32.6%) had a subsequent relapse to a second or later episode of psychosis. Of the 182 patients who did relapse, however, a large proportion (115 [63.2%]) reported threshold-level delusions. Of these 115, 104 patients (90.4%) had thematic delusion content consistent with that reported during the index (first) episode. Those who relapsed with delusions had fewer delusion themes present during subsequent episodes of psychosis compared with the index episode and lower levels of other psychotic and nonpsychotic symptoms.Conclusions and RelevanceSpecialized early intervention services for psychosis can achieve high rates of sustained remission. However, in this study, the minority of individuals with delusions who later relapsed experienced similar delusion themes during subsequent episodes. These findings raise important considerations for the conceptualization of delusions and have clinical implications for trajectories of illness and care.

Abstract

A key area of research in ecological statistics involves combining data sources from multiple streams to improve population estimates. One such model attempts to integrate capture–recapture and presence–absence data to estimate the population size of Eurasian lynx in the Jura Mountains, eastern France.

This model has been observed to underestimate population sizes. We conducted an extensive simulation study to evaluate the model's performance. We describe our methods for generation of simultaneous capture–recapture and presence–absence data and demonstrate that the model is flawed.

Finally, we give an outline of our hypothesis on why the model underestimates population sizes.

AbstractSuperhydrophobic surfaces garner tremendous research attention due to their potential applications in the fields of oil–water separation membrane, self‐cleaning, and anti‐icing systems. However, the reported superhydrophobic materials that achieve low‐surface‐tension (<60 mN m−1) liquid repellency are typically prepared using perfluorinated compounds (PFCs), which pose significant risks to the natural environment and human health. Here a concept based on the excluded volume effect in polymer dilute solutions is explored to achieve a hydrophobic flexible polymer‐chain wrapping of multidimensional particles, which forms a nonadherent soft‐shell‐hard‐core structure and maintains the original structural integrity of particles. The prepared fluoro‐free super‐repellent multidimensional particles can be spray‐coated and dip‐coated on different substrates to prepare large‐scale superhydrophobic coatings, which exhibit excellent low‐surface‐tension (42.6−50 mN m−1) liquid repellency superior to the reported fluoro‐free superhydrophobic materials. Benefiting from the strong interaction of super‐repellent particles with flexible polymer chains, the superhydrophobic coatings show unexpected wear resistance and durability. This first demonstration of hydrophobic polymer‐wrapped particles for repelling low‐surface‐tension liquids provides insights into next‐generation fluoro‐free superhydrophobic materials.

AbstractGarnet electrolyte Li6.5La3Zr1.5Ta0.5O12 (LLZTO) has been identified as a promising candidate for solid‐state batteries (SSBs). However, the implementation of garnet‐based SSBs is severely restricted owing to the Li dendrite originating from the uneven Li+ deposition and the electron leakage. Herein, one high‐performance garnet‐based SSB is proposed through the enhancement of interfacial dynamics and the inhibition of electron penetration, induced by an artificial harmonized interphase (LSF). The formation of a tightly bonded LLZTO|Li interface is facilitated by the Li3Sb with lower interfacial energies against LLZTO and Li, elucidated by the density functional theory (DFT) calculations. Furthermore, electron leakage and dendrite infiltration are effectively suppressed by the LiF with the electron‐insulating nature and an exceptional γE value. Therefore, a low interfacial resistance of 4.8 Ω cm2 is successfully achieved by the utilization of the functional LSF interphase layer, and the Li|LLZTO‐LSF|Li symmetric cell displayed prolonged Li plating/stripping stability over 1200 h at 0.3 mA cm−2. Moreover, the LFP|LLZTO‐LSF|Li full cell also exhibited notable cycling performance (93.1% capacity retention after 200 cycles at 1 C). The utilization of a synergistic interlayer has been identified as an effective strategy for the advancement of garnet‐based solid‐state lithium batteries.

AbstractEnabling minimally invasive and precise control of liquid release in dental implants is crucial for therapeutic functions such as delivering antibiotics to prevent biofilm formation, infusing stem cells to promote osseointegration, and administering other biomedicines. However, achieving controllable liquid cargo release in dental implants remains challenging due to the lack of wireless and miniaturized fluidic control mechanisms. Here wireless miniature pumps and valves that allow remote activation of liquid cargo delivery in dental implants, actuated and controlled by external magnetic fields (<65 mT), are reported. A magnet‐screw mechanism in a fluidic channel to function as a piston pump, alongside a flexible magnetic valve designed to open and close the fluidic channel, is proposed. The mechanisms are showcased by storing and releasing of liquid up to 52 µL in a dental implant. The liquid cargos are delivered directly to the implant–bone interface, a region traditionally difficult to access. On‐demand liquid delivery is further showed by a metal implant inside both dental phantoms and porcine jawbones. The mechanisms are promising for controllable liquid release after implant placement with minimal invasion, paving the way for implantable devices that enable long‐term and targeted delivery of therapeutic agents in various bioengineering applications.

Published: August 2024

Abstract4H‐SiC is a key enabler for realizing integrated electronics operating in harsh environments, which exhibit very high temperatures. Through advances in 4H‐SiC process technology, different sensor and circuit types have been demonstrated to operate stable at temperatures as high as 800 °C, paving the way toward harsh‐environment immune smart sensors. In this work, for the first time the operation of ion‐implanted 4H‐SiC Hall sensors realized in a wafer scale Bipolar‐CMOS‐DMOS technology is demonstrated at a wide operation temperature range spanning room temperature up to 500 °C in addition to short‐term operation up to 600 °C. The temperature‐dependent sensor characteristics of 15–22 samples are evaluated in terms of sensitivity and noise. The small inter‐device variations reflect the stability of the used process for very high temperature Hall sensors. The noise‐limited detectivity is further evaluated, revealing a best value of 950 nT/ and a mean detectivity of 1 µT/ at 500 °C. This is the best value reported up to date for very high temperature Hall sensors, besides being the first demonstration of ion‐implanted wide‐bandgap Hall sensors. Overall, the results reflect the potential of the demonstrated Hall sensors for the next generation of integrated magnetic field sensors in harsh environments.

AbstractWater molecules confined in nanoscale spaces of 2D graphene layers have fascinated researchers worldwide for the past several years, especially in the context of energy storage applications. The water molecules exchanged along with ions during the electrochemical process can aid in wetting and stabilizing the layered materials resulting in an anomalous enhancement in the performance of supercapacitor electrodes. Engineering of 2D carbon electrode materials with various functionalities (oxygen (─O), fluorine (─F), nitrile (─C≡N), carboxylic (─COOH), carbonyl (─C═O), nitrogen (─N)) can alter the ion/water organization in graphene derivatives, and eventually their inherent ion storage ability. Thus, in the current study, a comparative set of functionalized graphene derivatives—fluorine‐doped cyanographene (G–F–CN), cyanographene (G–CN), graphene acid (G–COOH), oxidized graphene acid (G‐COOH (O)) and nitrogen superdoped graphene (G–N) is systematically evaluated toward charge storage in various aqueous‐based electrolyte systems. Differences in functionalization on graphene derivatives influence the electrochemical properties, and the real‐time mass exchange during the electrochemical process is monitored by electrochemical quartz crystal microbalance (EQCM). Electrogravimetric assessment revealed that oxidized 2D acid derivatives (G–COOH (O)) are shown to exhibit high ion storage performance along with maximum water transfer during the electrochemical process. The complex understanding of the processes gained during supercapacitor electrode charging in aqueous electrolytes paves the way toward the rational utilization of graphene derivatives in forefront energy storage applications.
