Lecture capture: Practical recommendations for students and instructors

In this article, we provide practical recommendations to help promote self-regulated strategies for the use of lecture capture for both students and instructors. For students, we suggest that the importance of attendance and effective note-taking should be reinforced, as well as specifying how lecture capture can best be used as a catch-up or revision aid. For instructors, we highlight the need to provide guidance for students on how to learn and to adopt a context-dependent approach to lecture capture based on pedagogical considerations, rather than all-or-nothing. Regarding the issue of the relationship between lecture capture and attendance, we suggest the focus should move to a more nuanced discussion of why students fail to attend lectures and how they are using lecture capture. Finally, we discuss other concerns commonly raised by instructors related to lecture capture. Our student guidance is available for dissemination in infographic form at https://osf.io/esd2q/files/

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

Microscopic chaos from Brownian motion in a one-dimensional anharmonic oscillator chain

The problem of relating microscopic chaos to macroscopic behavior in a many-degrees-of-freedom system is numerically investigated by analyzing statistical properties associated to the position and momentum of a heavy impurity embedded in a chain of nearest-neighbor anharmonic Fermi-Pasta-Ulam oscillators. For this model we have found that the behavior of the relaxation time of the momentum autocorrelation function of the impurity is different depending on the dynamical regime (either regular or chaotic) of the lattice.Comment: 5 pages REVTeX, 6 eps figures, to appear in Phys.

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

An Optically Discovered Outburst from XTE J1859+226

Using the Zwicky Transient Facility, in 2021 February we identified the first known outburst of the black hole X-ray transient XTE J1859+226 since its discovery in 1999. The outburst was visible at X-ray, UV, and optical wavelengths for less than 20 days, substantially shorter than its full outburst of 320 days in 1999, and the observed peak luminosity was 2 orders of magnitude lower. Its peak bolometric luminosity was only 2 × 1035 erg s−1, implying an Eddington fraction of about 3 × 10−4. The source remained in the hard spectral state throughout the outburst. From optical spectroscopy measurements we estimate an outer disk radius of 1011 cm. The low observed X-ray luminosity is not sufficient to irradiate the entire disk, but we observe a surprising exponential decline in the X-ray light curve. These observations highlight the potential of optical and infrared synoptic surveys to discover low-luminosity activity from X-ray transients

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

Regulating for Responsibility: Reputation and Social Media

The framework brought forward by the United Kingdom's Defamation Act 2013 underlines a traditional hierarchy of expression in which news media are viewed as high-level speech. Although of a different form, social media are a dominant means of expression. The current study explores the rationale for a more robust and forceful discussion of responsibility in speech on social media platforms. The underlying premise here is that speech should be viewed as a qualified good and that a more appropriate paradigm is one found in the phrase ‘freedom to participate’

Active ageing, pensions and retirement in the UK

The ageing population has led to increasing concerns about pensions and their future sustainability. Much of the dominant policy discourse around ageing and pension provision over the last decade has focussed on postponing retirement and prolonging employment. These measures are central to productive notions of ‘active ageing’. Initially the paper briefly sets out the pension developments in the UK. Then it introduces active ageing and active ageing policy, exploring its implications for UK pension provision. It demonstrates that a more comprehensive active ageing framework, which incorporates a life-course perspective, has the potential to assist the UK to respond to the challenges of an ageing population. In doing so it needs to highlight older people as an economic and social resource, and reduce barriers to older people’s participation in society
