Implicating oneself in oppression provokes uncertainty, shame and anxiety, and identity destabilizations. Yet anti-oppressive texts often denigrate these experiences, participating in forces I call "compulsory sound-mindedness." Narratives of three women confronting their complicity illustrate the workings of compulsory sound-mindedness: a white Canadian recognizing the racism in her development work and both a white woman and a racialized Muslim reflecting on their complicity in ongoing Canadian colonization. The three narratives devalue affect, uncertainty, and destabilized identity. They also reveal these denigrated experiences as fundamental to personal-is-political ethical transformation. Compulsory sound-mindedness cannot consistently prevent people from journeying with pain, uncertainty, and coming undone. But when people undertake such journeys, compulsory sound-mindedness frames pain, identity destabilization, and uncertainty as regrettable and without value. I advocate that people cultivate a "troubled consciousness" by journeying with internalized accountability narratives, uncertainties, painful feelings, and destabilizations of a straightforwardly moral self.

There is a great deal of contemporary interest in improving schools in challenging contexts. However, there are relatively few research studies that have focused exclusively upon successful leadership practices in such schools. This article outlines the findings from a research study funded by the National College for School Leadership in England that explored successful leadership practices and school improvement strategies in a group of secondary schools in challenging circumstances.

The concept of building information modelling (BIM) under various names such as building product models has been around over 30 years. Other industries such as aerospace and automotive have used similar informational models on their products to analyse their design, performance and manufacturability. The architecture, engineering and construction industry is now moving towards the adoption of such concepts, driven by the need to be competitive in the market, to reduce cost and time, and to satisfy the government regulations. In view of the recent interest in BIM, this paper reports on the findings of several case study research projects and discusses how this innovative solution works in practice. The introductory sections discuss the current consistent problems that occur during the engineering design and production processes despite the introduction of good practice management techniques. Case study empirical data are used to provide insight regarding the implications for BIM development, implementation and execution. Collectively the barriers to adoption, benefits achievable and opportunities for the future are discussed with the help of illustration. The contribution to knowledge is a BIM state-of-the-art review and its potential in future engineering practice. © ICE Publishing: All rights reserved.

Purpose Following the boom of shale gas production in the USA and the decrease in the US gas prices, increasing interest in shale gas is developing in many countries holding shale reserves and exploration is already taking place in some EU countries, including the UK. Any commercial development of shale gas in Europe requires a broad environmental assessment, recognizing the different European conditions and legislations. Methods This study focuses on the UK situation and estimates the environmental impacts of shale gas using lifecycle assessment (LCA); the burdens of shale gas production in the UK are compared with the burdens of the current UK natural gas mix. The main focus is on the analysis of water impacts, but a broad range of other impact categories are also considered. A sensitivity analysis is performed on the most environmentally criticized operations in shale gas production, including flowback disposal and emission control, by considering a range of possible process options. Results and discussion Improper waste water management and direct disposal or spills of waste water to river can lead to high water and human ecotoxicity. Mining of the sand and withdrawal of the water used in fracking fluids determine the main impacts on water use and degradation. However, the water degradation of the conventional natural gas supply to the UK is shown to be even higher than that of shale gas. For the global warming potential (GWP), the handling methods of the emissions associated with the hydraulic fracturing influence the results only when emissions are vented. Finally, the estimated ultimate recovery of the well has the greatest impact on the results as well as the flowback ratio and flowback disposal method. Conclusions This paper provides insights to better understand the future development of shale gas in the UK. Adequate waste water management and emission handling significantly reduce the environmental impacts of shale gas production. Policy makers should consider that shale gas at the same time increases the water consumption and decreases the water degradation when compared with the gas mix supply. Furthermore, the environmental impacts of shale gas should be considered according to the low productivity that force the drilling and exploitation of a high number of wells.

Bioenergy is a renewable energy generated from biomass, while biofuel is a hydrocarbon fuel that is produced from biomass. Recently, bioenergy and biofuel projects are encouraged and supported by many governments and organizations in various ways such as providing incentives, technical supports, information, and decision support tools. Economic model is one of the decision support tools, which helps to estimate the costs and earnings involved in a project. It is constructed with various elements such as concepts, relations, logics, constants and equations. In current economic models, all the elements are hard coded into some programming code, which makes the model less reusable and extendable. To address the issue, we present an ontology-based economic model in this paper. In particular, we have leveraged the Semantic Web technologies to represent the knowledge about the bioenergy and biofuel economics and inferred the equations and other values required for economic calculations. The case study has been carried out in two of the INTERREG Projects and found promising results. © 2015 IEEE.

There is growing demand for dental education and training not only in terms of knowledge but also skills. This demand is driven by continuing professional development requirements in the more developed economies, personnel shortages and skills differences across the European Union (EU) accession states and more generally in the developing world. There is an excellent opportunity for the EU to meet this demand by developing an innovative online flexible learning platform (FLP). Current clinical online systems are restricted to the delivery of general, knowledgebased training with no easy method of personalization or delivery of skillbased training. The PHANTOM project, headed by Kings College London is developing haptic-based virtual reality training systems for clinical dental training. ANDROMEDA seeks to build on this and establish a Flexible Learning Platform that can integrate the haptic and sensor based training with rich media knowledge transfer, whilst using sophisticated technologies such as including service-orientated architecture (SOA), Semantic Web technologies, knowledge-based engineering, business intelligence (BI) and virtual worlds for personalization. © 2009 IFIP International Federation for Information Processing.

Effects of tactile feedback on movement accuracy and speed were studied. Younger and older participants performed three tasks (1, select and drag word; 2, menu navigation; 3, select and drag cell) using commercial software and a mouse with or without tactile feedback. Task time and error number were recorded. Tasks were divided according to presence or absence of tactile feedback, and participants were divided into subgroups (high, average, low) based on Task 1 performance. Overall, older participants took longer ( p < .0001) and made more errors ( p < .001) than younger participants. There was an effect of feedback by task in younger participants for all six outcomes ( p < 0.02). At the task level, with feedback, younger participants reduced performance time (13%) and errors (24%) on Task 1. Low-and average-performance younger participants benefited most from feedback for Task 1. Older low-performance participants also benefited from feedback for Task 1. For Task 3, older participants tended to take more time and make more errors with feedback. Tactile feedback may enhance performance when feedback is event related. Older people may not integrate sensation as well as younger individuals to enhance performance. Potential applications of this research include the development of tactile feedback interfaces to facilitate computer use.

Abstract
Purpose
Characterizing trends and correlates of adolescent psychological distress is important due to observed global increases over the last 20 years. Substance use is a commonly discussed correlate, though we lack an understanding about how co-occurrence of these concerns has been changing over time.

Methods
Data came from repeated, representative, cross-sectional surveys of grade 7–12 students across Ontario, Canada conducted biennially from 2013 to 2019. Poisson regression with robust standard errors was used to examine changes in the joint association between psychological distress (operationalized as Kessler-6 [K6] scores ≥ 13) and substance use over time. Weighted prevalence ratios (PR) and their 99% confidence intervals were estimated, where p < 0.01 denotes statistical significance.

Results
The prevalence of psychological distress doubled between 2013 and 2019, with adjusted increases of about 1.2 times each survey year. This biennial increase did not differ based on sex, perceived social standing, school level, or any substance use. Students using substances consistently reported a higher prevalence of psychological distress (between 1.2 times and 2.7 times higher). There were similarly no differential temporal trends based on substance use for very high distress (K6 ≥ 19) or K6 items explored individually.

Conclusion
Psychological distress steeply increased among adolescents and substance use remains important to assess and address alongside distress. However, the magnitude of temporal increases appears to be similar for adolescents reporting and not reporting substance use.
