Sustaining Critical Approaches to Translanguaging in Education: A Contextual Framework

Translanguaging remains a timely and important topic in bi/multilingual education. The most recent turn in translanguaging scholarship involves attention to translanguaging in context in response to critiques of translanguaging as a universally empowering educational practice. In this paper, seven early career translanguaging scholars propose a framework for researching translanguaging “in context,” drawing on the Douglas Fir Group\u27s (2016) transdisciplinary framework for language acquisition. Examining translanguaging in context entails paying attention to who in a classroom wields power, as a result of their greater proficiency in societally valued languages, their more “standard” ways of speaking these languages, their greater familiarity with academic literacies valued at school, and/or their more “legitimate” forms of translanguaging. In our framework for researching translanguaging in context, we propose three principles. The first principle is obvious: (1) not to do so apolitically. The other two principles describe a synergy between ethnographic research and teacher-researcher collaborative research: (2) ethnographic research can assess macro-level language ideologies and enacted language hegemonies at the micro- and meso levels, and (3) teacher-researcher collaborations must create and sustain inclusive, equitable classroom social orders and alternative academic norms different from the ones documented to occur in context if left by chance

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Gains in oral health and improved quality of life of 12-13-year-old Nepali schoolchildren: outcomes of an advocacy project to fluoridate toothpaste.

OBJECTIVES: To report on gains in oral health and improved quality of life of 12-13-year-old Nepali schoolchildren five and six years after the introduction of fluoride toothpaste in 1999. DESIGN: Cross sectional baseline surveys in 1999 and 2001, and follow up surveys in 2004 and 2005 were multi-stage cluster sampling in design. SETTING: Urban and rural schools in Central, Far Western, Mid Western and Western Developmental Regions of Nepal. PARTICIPANTS: 2,770, 12-13-year-olds in 1999 and 1,001, 12-13-year-olds in 2004 were examined regionally. 637 12-13-year-olds from Kathmandu valley and 448 12-13-year-olds from Tansen municipality were examined in 1999. The same schools in Kathmandu valley and Tansen were visited in 2005 and 761 and 482 12-13-years from Kathmandu valley and Tansen were examined. 6,064 8-15-year-olds in 2001 and 1,001 12-13-year-olds in 2004 participated in the collection of information on oral hygiene practice and quality of life. METHOD: Examinations were carried out by trained and calibrated examiners using the WHO diagnostic criteria for caries and questionnaires were interview administered by trained interviewers. Intervention: Advocacy for fluoride toothpaste between 1997 and 2002. RESULTS: There was a 26.6% decline in caries prevalence and 38.0% decrease in 12-13-year old DMFT from 1999 to 2004 throughout four of five regions of Nepal. Approximately 65-75% of the 12-13-year-olds used fluoride toothpaste from 1999 to 2004. School specific data reveals a reduction in DMFT of 43.8% in Tansen and 53.6% in the Kathmandu valley from 1999 to 2005. From 2001 to 2004, report of oral pain decreased by 10%. CONCLUSIONS: The most likely reason for the decline in dental caries and reduction in oral pain is the widespread consumption of fluoride toothpaste by the 12-13-year-old schoolchildren

Quantifying Escherichia Coli Release from Soil under High-Intensity Rainfall

Bacterial loading in surface runoff can only be reasonably assessed or predicted with quantitative knowledge of the release of bacteria from the soil under different rainfall conditions. Most studies of bacterial movement were conducted under rainfall intensities of less than 44 mm h-1. However, in the tropics, intensities higher than 44 mm h-1 are frequent. In this study, Escherichia coli release from the soil into surface runoff and its distribution in the soil under the impact of heavy rainfall (95 mm h-1) of different durations were investigated. Results of simulated heavy rainfall of different durations on gently sloping grass plots with spray-applied E. coli indicated that E. coli was released with relative ease, resulting in contaminated runoff. Runoff E. coli concentrations ranged from 2.09 log(CFU) mL -/ in 5 mill simulated rainfall events to 4.45 10g(CFU) mL -/ in 15 min simulated rainfall events. The first simulated rainfall events after spray applications J. ·roduced the highest concentration ofE. coli in the runoff. Runoff loss accounted for 0.001% of the total applied E. coli in 5 mill rainfall events and 2.1 % in 15 min rainfall events. Total solids explailled 28% of the variation in the concentrations and 14% of the total loadings. E. coli concentration in the surface centimeter of the soil explained 80% to 89% of the variations ill runoff concentrations and loadings with regression slope of less than ullity. Such quantitative relatiollships have the potential to predict runoff E. coli concentrations under high-intensity rainfall events

Efficacy of silver diamine fluoride for Arresting Caries Treatment.

Contains fulltext : 80819.pdf (publisher's version ) (Closed access)Arresting Caries Treatment (ACT) has been proposed to manage untreated dental caries in children. This prospective randomized clinical trial investigated the caries-arresting effectiveness of a single spot application of: (1) 38% silver diamine fluoride (SDF) with tannic acid as a reducing agent; (2) 38% SDF alone; (3) 12% SDF alone; and (4) no SDF application in primary teeth of 976 Nepalese schoolchildren. The a priori null hypothesis was that the different treatments have no effect in arresting active cavitated caries. Only the single application of 38% SDF with or without tannic acid was effective in arresting caries after 6 months (4.5 and 4.2 mean number of arrested surfaces; p < 0.001), after 1 year (4.1 and 3.4; p < 0.001), and after 2 years (2.2 and 2.1; p < 0.01). Tannic acid conferred no additional benefit. ACT with 38% SDF provides an alternative when restorative treatment for primary teeth is not an option

Situational analysis of dental caries and existing oral health care of children and adolescents in Hubei Province, People's Republic of China: implications for change.

Item does not contain fulltextPURPOSE: (1) To evaluate trends in dental caries of children and adolescents of Hubei Province and Wuhan Municipality over the last two decades. (2) To conduct a situational analysis of existing oral health care and to recommend changes to improve this care for children. MATERIALS AND METHODS: An analysis was performed on data from national oral health surveys carried out in China at the provincial level, and data on 12-year-old children of Wuhan Municipality. A review of the literature was conducted on available and utilised oral health care facilities by children. RESULTS: In 1983, the mean decayed, missing and filled teeth (DMFT) of 12-year-olds in Hubei Province was 1.0, and in 1995 it was 0.6. The studies in Wuhan Municipality in 1993-1995 among 12-year-olds reported DMFT values ranging from 0.7-1.5, however different methods of caries assessment were performed in the various studies making comparisons difficult. The caries prevalence and the mean dmft score of 5-year-old children in 1995 in Hubei Province were 69% and 3.6, respectively. The percentage of untreated caries for all age groups in Hubei Province was very high. CONCLUSIONS: Analysis of epidemiological information over the last two decades does not provide any conclusive evidence supporting either an increasing or decreasing trend of dental caries in the child and adolescent population of Hubei Province and Wuhan Municipality. There is, however, a clear need to prevent the incidence of dental caries from increasing and to provide care to address the treatment needs of pre-school and school-age children. The promotion of twice-daily tooth brushing with fluoride toothpaste at maternal and child health care centres, and the establishment of daily tooth brushing with pea-size amounts of fluoride toothpaste in the pre-school and primary school setting are recommended preventive strategies. Establishment of school-based oral health promotion should be accompanied with the provision of Atraumatic Restorative Treatment (ART) sealants and ART restorations which can be provided by dental nurses at dramatically lower costs than the traditional high-tech approach

A fiber Bragg grating sensor system for train axle counting

Railway signaling facilitates two main functions, namely, train detection and train control, in order to maintain safe separations among the trains. Track circuits are the most commonly used train detection means with the simple open/close circuit principles; and subsequent adoption of axle counters further allows the detection of trains under adverse track conditions. However, with electrification and power electronics traction drive systems, aggravated by the electromagnetic interference in the vicinity of the signaling system, railway engineers often find unstable or even faulty operations of track circuits and axle counting systems, which inevitably jeopardizes the safe operation of trains. A new means of train detection, which is completely free from electromagnetic interference, is therefore required for the modern railway signaling system. This paper presents a novel optical fiber sensor signaling system. The sensor operation, field setup, axle detection solution set, and test results of an installation in a trial system on a busy suburban railway line are given
