The Impact

Changes to the labour process in the home credit sector have exposed the industry’s agency workforce to increased levels of digital managerial control through the introduction of lending applications and algorithmic decision-making techniques. This article highlights the heterogeneous nature of the impact of digitalisation on the labour process and worker autonomy – specifically, in terms of workers’ engagement in unquantified emotional labour. By considering the limitations of digital control in relation to qualitative elements of the labour process, it becomes evident that emotional labour has the scope to be a source of autonomy for dependent self-employed workers when set against a backdrop of heightened digital control. This article therefore contributes to ongoing labour process debates surrounding digitalisation, quantified workers and digital managerial control.

Abstract Extracellular vesicles (EVs) are small particles that are naturally released from various types of cells. EVs contain a wide variety of cellular components, such as proteins, nucleic acids, lipids and metabolites, which facilitate intercellular communication in diverse biological processes. In the tumour microenvironment, EVs have been shown to play important roles in tumour progression, including immune system–tumour interactions. Although previous studies have convincingly demonstrated the immunosuppressive functions of tumour-derived EVs, some studies have suggested that tumour-derived EVs can also stimulate host immunity, especially in therapeutic conditions. Recent studies have revealed the heterogeneous nature of EVs with different structural and biological characteristics that may account for the divergent functions of EVs in tumour immunity. In this review article, we provide a brief summary of our current understanding of tumour-derived EVs in immune activation and inhibition. We also highlight the emerging utility of EVs in the diagnosis and treatment of cancers and discuss the potential clinical applications of tumour-derived EVs.

The operation of the smart grid is anticipated to rely profoundly on distributed microprocessor-based control. Therefore, interoperability standards are needed to address the heterogeneous nature of the smart grid data. Since the IEC 61850 emerged as a wide-spread interoperability standard widely accepted by the industry, the Sampled Measured Values method has been used to communicate digitized voltage and current measurements. Realizing that current and voltage measurements (i.e., feedback measurements) are necessary for reliable and secure noperation of the power grid, firstly, this manuscript provides a detailed analysis of the Sampled Measured Values protocol emphasizing its advantages, then, it identifies vulnerabilities in this protocol and explains the cyber threats associated to these vulnerabilities. Secondly, current efforts to mitigate these vulnerabilities are outlined and the feasibility of using neural network forecasters to detect spoofed sampled values is investigated. It was shown that although such forecasters have high spoofed data detection accuracy, they are prone to the accumulation of forecasting error. Accordingly, this paper also proposes an algorithm to detect the accumulation of the forecasting error based on lightweight statistical indicators. The effectiveness of the proposed methods is experimentally verified in a laboratory-scale smart grid testbed.

Background: The authors of this article ‘Measuring the vulnerability of sub-national regions in South Africa’ (Naudé, McGillivray and Rossouw 2009b) present an exploration into economic vulnerability from a sub-national perspective. It is an important contribution because it recognises the heterogeneous nature of vulnerability across areas within a country, but its analysis is aspatial because it does not explicitly account for the relative location of or the potential for spillovers between areas.Aim: This article aims to provide a purely methodological contribution towards the debate surrounding the measurement of multidimensional vulnerability by: (1) augmenting Naudé et al. (2009b)’s model to take account of spatial contiguity, (2) comparing spatial and aspatial local vulnerability indices estimates to illustrate the presence and importance of spatial spillovers between contiguous areas and (3) extending their methodology on the Vulnerability Intervention Index to present results which highlight areas that are performing better and worse than expected.Methods: Principal components analysis, queen-contiguity weight matrix and local indication of spatial association (LISA) maps were utilised.Results: Application of the methodological extensions to South African Magisterial District data illustrates the presence and importance of spatial spillovers in shaping local vulnerability.Conclusions: Our results illustrate a clear urban–rural vulnerability divide and the need for appropriate policy. It is argued that account of spatial spillovers is an important issue if full and accurate vulnerability indices are to be identified.

The sediment of #3 Well of the Greater Ughelli Depobelt are represented by sand and shale intercalation. In this study, lithofacies analysis and X-ray diffraction technique were used to characterize the sediments from the well. The lithofacies analysis was based on the physical properties of the sediments encountered from the ditch cuttings.  Five lithofacies types of mainly sandstone, clayey sandstone, shaly sandstone, sandy shale and shale and 53 lithofacies zones were identified from 15 ft to 11295 ft. The result of the X-ray diffraction analysis identified that the following clay minerals – kaolinite, illite/muscovite, sepiolite, chlorite, calcite, dolomite; with kaolinite in greater percentage. The non-clay minerals include quartz, pyrite, anatase, gypsum, plagioclase, microcline, jarosite, barite and fluorite; with quartz having the highest percentage. Therefore, due to the high percentage of kaolinite in #3 well, the pore filing kaolinite may have more effect on the reservoir quality than illite/muscovite, chlorite and sepiolite. By considering the physical properties, homogenous and heterogeneous nature of the #3 Well, it would be concluded that #3 Well has some prospect for petroleum and gas exploration.

Broad Overview

The availability of epidemiological data relating to interstitial lung diseases (ILDs) has increased over recent years, but information on the prevalence and incidence of ILDs of different aetiologies remains limited. Despite global distribution, the proportion of patients who develop a progressive phenotype across different ILDs is not well known. Disease behaviour is well documented in idiopathic pulmonary fibrosis but idiosyncratic in other ILDs that may present a progressive fibrosing phenotype. Possible reasons may include the heterogeneous nature of the aetiology, the complexity of diagnosis (and subsequent documentation of cases) and the methods employed to retrospectively analyse patient databases. This review presents a broad overview of the epidemiological data available for ILDs that may present a progressive-fibrosing phenotype, collectively and stratified according to clinical classification. We also note where further data are needed in comparison to the well-studied IPF indication.
