Head-Tracking Haptic Computer Interface for the Blind

In today’s heavily technology-dependent society, blind and visually impaired people are becoming increasingly disadvantaged in terms of access to media, information, electronic commerce, communications and social networks. Not only are computers becoming more widely used in general, but their dependence on visual output is increasing, extending the technology further out of reach for those without sight. For example, blindness was less of an obstacle for programmers when command-line interfaces were more commonplace, but with the introduction of Graphical User Interfaces (GUIs) for both development and final applications, many blind programmers were made redundant (Alexander, 1998; Siegfried et al., 2004). Not only are images, video and animation heavily entrenched in today’s interfaces, but the visual layout of the interfaces themselves hold important information which is inaccessible to sightless users with existing accessibility technology

Creative non-compliance : Complying with the “spirit of the law” not the “letter of the law” under the Covid-19 lockdown restrictions

This paper identifies a form of non-compliance with COVID-19 lockdown restrictions in the UK: “creative non-compliance”. Here, individuals justify breaking restrictions as meeting the “spirit of the law” if not the “letter of the law”. Drawing on interview and focus group data collected between April and August 2020 in the UK, we outline this concept of “creative non-compliance”, detailing how: (i) our participants undertook a purposive construction of rules, (ii) balanced their behaviour against these aims, and (iii) how Government messaging informed these rationalizations. We conclude by outlining the implications of our “creative non-compliance” theory both for studies of compliance and rationalizations for deviant behaviour under the COVID-19 restrictions

Metal sorption by biochars : a trade-off between phosphate and carbonate concentration as governed by pyrolysis conditions

Three feedstocks, pine wood, grass and cow manure, were pyrolyzed under various conditions and tested on their ability to sorb metals in aquatic systems. The feedstocks were pyrolyzed at 2 different temperatures (350 degrees C and 550 degrees C) and 2 different residence times (10 and 60 min) and resulting biochars were assessed on their capability to immobilize Pb, Cu, Cd and Zn. Manure-based chars, and to a lesser extent grass-based chars, featured high concentrations of phosphates and carbonates, These anions play an important role in metal sorption because they form insoluble complexes with the metals. Washing reduced the concentration of these anions, leading to a reduced sorption of metals by the biochar. The carbonate concentration on the biochars' surface increased at higher reactor temperature and longer residence times. The opposite trend was observed for the phosphate concentration and the cation exchange capacity. Accordingly, the optimal temperature-residence time combination for sorption was a trade-off between these properties. Biochar produced from cow manure and pyrolyzed at 550 degrees C for 10 min showed the best sorption for all metals considered

Why the UK complied with COVID-19 lockdown law

In March 2020, the UK introduced a set of rules to ‘lockdown’ the country in response to the COVID-19 pandemic. The lockdown constituted a key feature of governmental efforts to manage the early stages of the pandemic. Evidence suggests that the lockdown attracted high levels of compliance. Yet, a question remains about exactly why the UK public complied. Based on a major empirical study, this article explores what drove legal compliance during the UK’s first lockdown. We find that legal compliance was dominated by normative concerns with the legitimacy of law. Yet, the public’s attachment to the legitimacy of law in general was undermined by concerns about the legitimacy of lockdown law specifically. Such specific legitimacy assessments were informed by people’s rights consciousness, their sense of obligation to others, perceptions of personal health vulnerability and assessments of the rules’ effectiveness in preventing virus transmission. The prospect of peer disapproval for beaching lockdown also proved significant, with the perceived risk of sanctions imposed by the police predicting fear of peer disapproval. The article concludes by considering what lessons might be learned about the use of legal rules to rapidly shape public behaviour in times of crisis

Undermining loyalty to legality? An empirical analysis of perceptions of 'lockdown' law and guidance during COVID-19

This article substantially extends the existing constitutional and legal critiques of the use of soft law public health guidance in the UK during the COVID-19 pandemic. Drawing upon the findings of a national survey undertaken during the first wave of the pandemic in June 2020, it shows how the perceived legal status of lockdown rules made a significant difference as to whether the UK public complied with them and that this effect is a product of the legitimacy that law itself enjoys within UK society. Based on this analysis, it argues that the problems with the government's approach to guidance, that have been subjected to criticism in constitutional and legal terms, may also be open to critique on the basis that they risk undermining the public's loyalty to the law itself

Law and Compliance during COVID-19

The Law and Compliance during COVID-19 project sought to answer a critical question: what drove public compliance – and non-compliance – with lockdown laws across the UK during the early stages of the pandemic? Our focus was on what people thought the law was, and how they behaved in relation to it. Through surveys, interviews, and focus groups with the public during 2020, our aim was to understand how the public responded to the lockdown restrictions that they believed to be legal rules. This report sets out our key findings

A Lung Segmental Model of Chronic <em>Pseudomonas</em> Infection in Sheep

Chronic lung infection with Pseudomonas aeruginosa is a major contributor to morbidity, mortality and premature death in cystic fibrosis. A new paradigm for managing such infections is needed, as are relevant and translatable animal models to identify and test concepts. We sought to improve on limitations associated with existing models of infection in small animals through developing a lung segmental model of chronic Pseudomonas infection in sheep.Using local lung instillation of P. aeruginosa suspended in agar beads we were able to demonstrate that such infection led to the development of a suppurative, necrotising and pyogranulomatous pneumonia centred on the instilled beads. No overt evidence of organ or systemic compromise was apparent in any animal during the course of infection. Infection persisted in the lungs of individual animals for as long as 66 days after initial instillation. Quantitative microbiology applied to bronchoalveolar lavage fluid derived from infected segments proved an insensitive index of the presence of significant infection in lung tissue (>10(4) cfu/g).The agar bead model of chronic P. aeruginosa lung infection in sheep is a relevant platform to investigate both the pathobiology of such infections as well as novel approaches to their diagnosis and therapy. Particular ethical benefits relate to the model in terms of refining existing approaches by compromising a smaller proportion of the lung with infection and facilitating longitudinal assessment by bronchoscopy, and also potentially reducing animal numbers through facilitating within-animal comparisons of differential therapeutic approaches

The epidemiology of enterococci

The enterococci are emerging as a significant cause of nosocomial infections, accounting for approximately 10 % of hospital acquired infections. They are found as normal inhabitants of the human gastrointestinal tract, but may also colonize the oropharynx, vagina, perineal region and soft tissue wounds of asymtomatic patients. Until recently, evidence indicated that most enterococcal infections arose from patients' own endogenous flora. Recent studies, however, suggest that exogeneous acquisition may occur and that person-to-person spread, probably on the hands of medical personnel, may be a significant mode of transmission of resistant enterococci within the hospital. The use of broad-spectrum antibiotics, especially cephalosporins, is another major factor in the increasing incidence of enterococcal infections. These findings suggest that barrier precautions, as applied with other resistant nosocomial pathogens, along with more judicial use of antibiotics may be beneficial in preventing nosocomial spread of resistant enterococci.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47899/1/10096_2005_Article_BF01963631.pd
