Experimental and computational studies of jamming

Jamming is a common feature of out of equilibrium systems showing slow relaxation dynamics. Here we review our efforts in understanding jamming in granular materials using experiments and computer simulations. We first obtain an estimation of an effective temperature for a slowly sheared granular material very close to jamming. The measurement of the effective temperature is realized in the laboratory by slowly shearing a closely-packed ensemble of spherical beads confined by an external pressure in a Couette geometry. All the probe particles, independent of their characteristic features, equilibrate at the same temperature, given by the packing density of the system. This suggests that the effective temperature is a state variable for the nearly jammed system. Then we investigate numerically whether the effective temperature can be obtained from a flat average over the jammed configuration at a given energy in the granular packing, as postulated by the thermodynamic approach to grains.Comment: 20 pages, 9 figure

The victorious English language: hegemonic practices in the management academy

This study explores hegemonic linguistic processes, that is, the dominant and unreflective use of the English language in the production of textual knowledge accounts. The authors see the production of management knowledge as situated in central or peripheral locations, which they examine from an English language perspective. Their inquiry is based on an empirical study based on the perspectives of 33 management academics (not English language speakers) in (semi) peripheral locations, who have to generate and disseminate knowledge in and through the English language. Although the hegemony of the center in the knowledge production process has long been acknowledged, the specific contribution of this study is to explore how the English language operates as part of the “ideological complex” that produces and maintains this hegemony, as well as how this hegemony is manifested at the local level of publication practices in peripherally located business and management schools

Education and older adults at the University of the Third Age

This article reports a critical analysis of older adult education in Malta. In educational gerontology, a critical perspective demands the exposure of how relations of power and inequality, in their myriad forms, combinations, and complexities, are manifest in late-life learning initiatives. Fieldwork conducted at the University of the Third Age (UTA) in Malta uncovered the political nature of elder-learning, especially with respect to three intersecting lines of inequality - namely, positive aging, elitism, and gender. A cautionary note is, therefore, warranted at the dominant positive interpretations of UTAs since late-life learning, as any other education activity, is not politically neutral.peer-reviewe

Mathematical formulation of quantum circuit design problems in networks of quantum computers

In quantum circuit design, the question arises how to distribute qubits, used in algorithms, over the various quantum computers, and how to order them within a quantum computer. In order to evaluate these problems, we define the global and local reordering problems for distributed quantum computing. We formalise the mathematical problems and model them as integer linear programming problems, to minimise the number of SWAP gates or the number of interactions between different quantum computers. For global reordering, we analyse the problem for various geometries of networks: completely connected networks, general networks, linear arrays and grid-structured networks. For local reordering, in networks of quantum computers, we also define the mathematical optimisation problem

Native-English-Speaking Teachers:Disconnections Between Theory, Research, and Practice

Native-English-speaking teachers (NESTs) have long been in demand for perceived benefits of the skills they bring to the classroom. However, the notion that native speakers provide the best models of the target language and thus make the best teachers of the language has been criticised in the literature. This article reports on the disconnection between academic literature on NESTs and the realities they report. Drawing on data from an investigation into NEST schemes globally, the article suggests that lived classroom experiences of NESTs are complex, They are also often bilingual, experienced, and qualified, and regard local English teachers (LETs) they work with as experts and in control of how English is practised in the classroom. These characteristics contrast with much of the academic literature, which explores the concept of native speakerism, which tends to view NESTs negatively. The article proposes that one reason for the disconnection between theory and practice is the parallel lives of researchers and teachers, whether NESTs or LETs. Thus, each group’s realities and concerns are not always understood by the other. The article suggests that a substantial group of bilingual and bicultural NESTs consider the country where work home, so future theorisations of NESTs and native speakerism should take account of these teachers

Care Planning for Community-Dwelling People with Dementia: A Systematic Scoping Review

Published 10 February 2023People with dementia and their care partners report a lack of support, treatment, and information, fragmented services, and a lack of inclusion in decisions about their care. Care planning may address these issues; however, there is scarce literature on the process or benefits of care planning for people with dementia. This review describes the literature on care planning for community-dwelling people with dementia and their care partners. A systematic scoping methodology was followed to identify the research questions, identify relevant documents, select relevant documents, chart the data, and collate, summarise, and report the results. 31 full-text documents published between 2010 and May 2020 were identified and reviewed. Seven were guidelines, seven were expert opinion pieces, 11 were intervention studies, and six were descriptive studies. The topics and process of care planning varied depending on the service context (e.g., memory clinic, home care, and primary care). Care planning was presented as a component of case management in 15 papers. Six of the 11 intervention studies reported positive outcomes, one showed no improvement, and one did not evaluate outcomes for people with dementia or their care partners. Of the six with positive outcomes, four evaluated care planning in the context of care management. There is limited evidence that care planning alone improves outcomes for people with dementia and their care partners. It is unclear whether it may have benefits when combined with care management.Lee-Fay Low, Tanya J. Duckworth, Lauren King, Meredith Gresham, Lyn Phillipson, Yun-Hee Jeon, and Henry Brodat
