    Introducing Registered Reports at Language Learning: Promoting Transparency, Replication, and a Synthetic Ethic in the Language Sciences

    Get PDF
    The past few years have seen growing interest in open science practices, which include initiatives to increase transparency in research methods, data collection, and analysis, to enhance accessibility to data and materials, and to improve the dissemination of findings to broader audiences. Language Learning is enhancing its participation in the open science movement by launching Registered Reports as an article category as of 1 January 2018. Registered Reports allow authors to submit the conceptual justifications and the full method and analysis protocol of their study to peer review prior to data collection. High quality submissions then receive provisional, in-principle acceptance. Provided that data collection, analyses, and reporting follow the proposed and accepted methodology and analysis protocols, the paper is subsequently publishable whatever the findings. We outline key concerns leading to the development of Registered Reports, describe its core features, and discuss some of its benefits and weaknesses

    Introduction of Methods Showcase Articles in Language Learning

    Get PDF
    Building on initiatives to promote high quality methodologies and Open Science practices in the language sciences, Language Learning will introduce, as of March 2020, a new manuscript type entitled Methods Showcase Articles (MSAs). The purpose of MSAs is to introduce new or emerging qualitative and quantitative methods, techniques, or instrumentation for language data collection, cleaning, sampling, coding, scoring, and analysis. MSAs are intended to describe methods and provide detailed examples of their application such that language researchers can easily adopt or adapt them in future studies. In this editorial, we outline the goals, format, and benefits of MSAs, discuss how they can advance language sciences, and discuss potential concerns

    Agricultural Turns, Geographical Turns: Retrospect and Prospect.

    Get PDF
    It is accepted that British rural geography has actively engaged with the ‘cultural turn’, leading to a resurgence of research within the sub-discipline. However, a reading of recent reviews suggests that the cultural turn has largely, if not completely, bypassed those geographers interested in the agricultural sector. Farming centred engagements with notions of culture have been relatively limited compared with those concerned with the non-agricultural aspects of rural space. Indeed, agricultural geography represents something of an awkward case in the context of the disciplinary turn to culture, a situation that demands further exposition. In seeking explanation, it becomes evident that research on the farm sector is more culturally informed than initially appears. This paper argues that there have been both interesting and important engagements between agricultural geography and cultural perspectives over the past decade. The paper elaborates four specific areas of research which provide evidence for concern about the ‘culture’ within agriculture. The future contribution that culturally informed perspectives in geographical research can bring to agricultural issues is outlined by way of conclusion

    Essential prescribing tips for GP Associates-in-Training

    Prescribing is an essential role in general practice but it is also, at times, a high risk activity. GP Associates-in-Training (GP AiTs) have been highlighted as needing further support to reduce the risk of prescribing errors. This article highlights some common prescribing errors to help GP AiTs to review their prescribing and develop prescribing habits to avoid errors. The general practice workforce is changing and there are more pharmacists working in general practice. This article describes the role of clinical pharmacists in prescribing safety and in supporting GP AiTs

    Adjustment Strategies Revisited: Agricultural Change in the Welsh Marches

    Get PDF
    In the late 1980s and early 1990s, much attention was paid by British agricultural geographers to the restructuring of the farm sector under pressures of national, European and global change. The need to adopt a perspective capable of looking beyond the farm gate inspired the introduction of modified political economy approaches into agricultural research. One important cornerstone of the empirical application of this thesis was the concept of the ‘farm adjustment strategy’. This attempted to map out the responses, especially those of survival, made by farm family businesses to rapidly changing agrarian conditions. Subsequently, the farm adjustment strategy became remarkable for its popularity as a way to organise research into agricultural change in developed market economies. Following a retreat in the 1990s, there has been something of a recent revival in the use of the term ‘strategy’ relating to agricultural adjustment. Revisiting this concept is therefore timely. Using empirical evidence from studies of farming change in the Welsh Marches, this paper examines two issues. First, it makes a critical reexamination of the concept to resolve differences with interpretation linked to theoretical perspectives so that future misuse can be minimised. Second, an attempt is made to assess the relevance of defined elements of farm adjustment strategies to analyses of farm business change. In so doing, there is an attempt to recover our knowledge of agrarian restructuring and to help situate newly encultured investigations into the likely survival of family labour-based forms of production

    The Atacama Cosmology Telescope: A Measurement of the Thermal Sunyaev-Zel'dovich Effect Using the Skewness of the CMB Temperature Distribution

    Get PDF
    We present a detection of the unnormalized skewness induced by the thermal Sunyaev-Zel'dovich (tSZ) effect in filtered Atacama Cosmology Telescope (ACT) 148 GHz cosmic microwave background temperature maps. Contamination due to infrared and radio sources is minimized by template subtraction of resolved sources and by constructing a mask using outlying values in the 218 GHz (tSZ-null) ACT maps. We measure = -31 +- 6 \mu K^3 (measurement error only) or +- 14 \mu K^3 (including cosmic variance error) in the filtered ACT data, a 5-sigma detection. We show that the skewness is a sensitive probe of sigma_8, and use analytic calculations and tSZ simulations to obtain cosmological constraints from this measurement. From this signal alone we infer a value of sigma_8= 0.79 +0.03 -0.03 (68 % C.L.) +0.06 -0.06 (95 % C.L.). Our results demonstrate that measurements of non-Gaussianity can be a useful method for characterizing the tSZ effect and extracting the underlying cosmological information.Comment: 9 pages, 5 figures. Replaced with version accepted by Phys. Rev. D, with improvements to the likelihood function and the IR source treatment; only minor changes in the result

    The Atacama Cosmology Telescope: Detection or Sunyaev-Zel'Dovich Decrement in Groups and Clusters Associated with Luminous Red Galaxies

    Get PDF
    We present a detection of the Sunyaev-Zel'dovich (SZ) decrement associated with the Luminous Red Galaxy (LRG) sample of the Sloan Digital Sky Survey. The SZ data come from 148 GHz maps of the equatorial region made by the Atacama Cosmology Telescope (ACT). The LRG sample is divided by luminosity into four bins, and estimates for the central Sunyaev-Zel'dovich temperature decrement are calculated through a stacking process. We detect and account for a bias of the SZ signal due to weak radio sources. We use numerical simulations to relate the observed decrement to Y(sub 200) and clustering properties to relate the galaxy luminosity bins to mass. We also use a relation between BCG luminosity and cluster mass based on stacked gravitational lensing measurements to estimate the characteristic halo masses. The masses are found to be in the range approx.10(exp 13) - 10(exp 14)/h Stellar Mass, a lower range than has been previously probed

    A measurement of the millimetre emission and the Sunyaev-Zel'dovich effect associated with low-frequency radio sources

    We present a statistical analysis of the millimetre-wavelength properties of 1.4GHz-selected sources and a detection of the Sunyaev–Zel’dovich (SZ) effect associated with the haloes that host them. We stack data at 148, 218 and 277GHz from the Atacama Cosmology Telescope at the positions of a large sample of radio AGN selected at 1.4GHz. The thermal SZ effect associated with the haloes that host the AGN is detected at the 5σ level through its spectral signature, representing a statistical detection of the SZ effect in some of the lowest mass haloes (average M 200 ≈ 10 13 M. h −1 70 ) studied to date. The relation between the SZ effect and mass (based on weak lensing measurements of radio galaxies) is consistent with that measured by Planck for local bright galaxies. In the context of galaxy evolution models, this study confirms that galaxies with radio AGN also typically support hot gaseous haloes. Adding Herschel observations allows us to show that the SZ signal is not significantly contaminated by dust emission. Finally, we analyse the contribution of radio sources to the angular power spectrum of the cosmic microwave background

    Protection against SARS-CoV-2 Omicron BA.4/5 variant following booster vaccination or breakthrough infection in the UK

    Get PDF
    Following primary SARS-CoV-2 vaccination, whether boosters or breakthrough infections provide greater protection against SARS-CoV-2 infection is incompletely understood. Here we investigated SARS-CoV-2 antibody correlates of protection against new Omicron BA.4/5 (re-)infections and anti-spike IgG antibody trajectories after a third/booster vaccination or breakthrough infection following second vaccination in 154,149 adults ≥18 y from the United Kingdom general population. Higher antibody levels were associated with increased protection against Omicron BA.4/5 infection and breakthrough infections were associated with higher levels of protection at any given antibody level than boosters. Breakthrough infections generated similar antibody levels to boosters, and the subsequent antibody declines were slightly slower than after boosters. Together our findings show breakthrough infection provides longer-lasting protection against further infections than booster vaccinations. Our findings, considered alongside the risks of severe infection and long-term consequences of infection, have important implications for vaccine policy
