Beyond Bourdieu, Foucault and Habermas: Review and Assessment of Critical Information Systems Research

This paper presents a literature review of critical information systems (IS) research. Specifically, it focuses on how IS researchers have responded to Myers and Klein’s (2011) call to consider critical approaches and theorists in addition Bourdieu, Foucault and Habermas. The review identifies and discusses three types of critical IS research “beyond Bourdieu, Foucault and Habermas”: work based on a) (other) critical grand social theories, b) postcolonialism and c) data-focused critical methods (i.e., Capabilities Approach, Critical Discourse Analysis, Critical Heuristics and Design, Frame Analysis and Phronetic Enquiry). Based on the literature review, the paper maps the landscape of critical approaches and theories and identify their origins. This analysis is helpful for IS researchers interested in conducting critical IS research by charting the range of critical research approaches beyond Bourdieu, Foucault and Haberma

Editorial: Beyond the Factory Paradigm: Digital Nomadism and the Digital Future(s) of Knowledge Work Post-COVID-19

What are the potential futures of knowledge work, given its transformation into almost exclusively digital work during the COVID-19 pandemic crisis? Our ongoing research program on digital nomadism informs a Hegelian dialectical analysis and an envisioning of the future(s) of knowledge work. We contrast the Factory paradigm of work (thesis), exemplified by the “ideal type” of the 9-to-5 corporate worker, with the Hypermobility paradigm of work (antithesis), exemplified by the ideal type of the digital nomad. Reflecting on this contrast, we envision the possible digital futures of knowledge work as a continuous spectrum, ranging from a future based on the Digital Taylorism paradigm of work to a future based on the Worker Autonomy paradigm of work. These futures are discussed in terms of different approaches to organizing work, working with technology, delineating work/life boundaries, and provisioning the social safety net. IS researchers are uniquely positioned to perform research and inform decision-making in all these areas, and thus make a difference in determining whether the future we end up with more closely resembles Digital Taylorism or the Worker Autonomy vision

CC's for the CIO - Core competencies for the chief information officer

The role of the modern-day Chief Information Officer (CIO) is multi-faceted, dynamic, inherently pressured and complex, and one which requires a multidisciplinary knowledge and skill-set. As the executive charged with the responsibility of managing the fast changing and complex Information Systems (IS) and Information Technology (IT) function, the modern-day CIO must possess and continually develop a wide range of diverse competencies. Today's CIO is required to take a much broader role in the business, drive business transformation, innovate for competitive advantage and act as a key strategic partner within the wider organisation. This study reports preliminary findings from 30 Australian CIOs on the identification of core competencies and is part of a larger body of work leading to the development of a CIO Competency Framework - for use by both practitioners and researchers to help bridge the gap between practice and theory and aid in CIO succession planning

Digital Work and High-Tech Wanderers: Three Theoretical Framings and a Research Agenda for Digital Nomadism

This paper presents a literature review and conceptual development of digital nomadism. Digital nomadism is characterised by mobile workers indefinitely travelling between different locations while continually fulfilling their work obligations. The emerging literature on digital nomadism is fragmented and primarily focused on digital nomads’ lifestyles. There is comparatively less focus on theoretically framing digital nomadism into broader narratives in human history. In order to gain a holistic understanding, this paper reviews the limited literature on digital nomadism and expands to other relevant literatures on economy (e.g., traditional boundaries in business), culture (e.g., lifehacking), and technology (e.g., telework and digital communication). These three theoretical framings of digital nomadism enable this paper to identify the current state of knowledge relevant to digital nomadism and develop a research agenda

Satellite-derived bathymetry in optically complex waters using a model inversion approach and Sentinel-2 data

This study presents an assessment of a model inversion approach to derive shallow water bathymetry in optically complex waters, with the aim of both understanding localised capability and contributing to the global evaluation of Sentinel-2 for coastal monitoring. A dataset of 12 Sentinel-MSI images, in three different study areas along the Irish coast, has been analysed. Before the application of the bathymetric model two atmospheric correction procedures were tested: Deep Water Correction (DWC) and Case 2 Regional Coastal Color (C2RCC) processor. DWC outperformed C2RCC in the majority of the satellite images showing more consistent results. Using DWC for atmospheric correction before the application of the bathymetric model, the lowest average RMSE was found in Dublin Bay (RMSE ¼ 1.60, bias ¼ \u100000 0.51), followed by Mulroy Bay (RMSE ¼ 1.66, bias ¼ 1.30) while Brandon Bay showed the highest average error (RMSE ¼ 2.43, bias ¼ 1.86). However, when the optimal imagery selection was considered, depth estimations with a bias less than 0.1 m and a spread of 1.40 m were achieved up to 10 m. These results were comparable to those achieved by empirical tuning methods, despite not relying on any in situ depth data. This conclusion is of particular relevance as model inversion approaches might allow future modifications in crucial parts of the processing chain leading to improved results. Atmospheric correction, the selection of optimal images (e.g. low turbidity), the definition of suitably limited ranges for the per-pixel occurrence of optical constituents (phytoplankton, CDOM, backscatter) and seabed reflectances, in combination with the understanding of the specifics characteristics at each particular site, were critical steps in the derivation of satellite bathymetry

GEOMETRIC PROCESSING OF VERY HIGH-RESOLUTION SATELLITE IMAGERY: QUALITY ASSESSMENT FOR 3D MAPPING NEEDS

In recent decades, the geospatial domain has benefitted from technological advances in sensors, methodologies, and processing tools to expand capabilities in mapping applications. Airborne techniques (LiDAR and aerial photogrammetry) generally provide most of the data used for this purpose. However, despite the relevant accuracy of these technologies and the high spatial resolution of airborne data, updates are not sufficiently regular due to significant flight costs and logistics. New possibilities to fill this information gap have emerged with the advent of Very High Resolution (VHR) optical satellite images in the early 2000s. In addition to the high temporal resolution of the cost-effective datasets and their sub-meter geometric resolutions, the synoptic coverage is an unprecedented opportunity for mapping remote areas, multi-temporal analyses, updating datasets and disaster management. For all these reasons, VHR satellite imagery is clearly a relevant study for National Mapping and Cadastral Agencies (NMCAs). This work, supported by EuroSDR, summarises a series of experimental analyses carried out over diverse landscapes to explore the potential of VHR imagery for large-scale mapping

A comparison of Landsat 8, RapidEye and Pleiades products for improving empirical predictions of satellite-derived bathymetry

Satellite derived bathymetry (SDB) enables rapid mapping of large coastal areas through measurement of optical penetration of the water column. The resolution of bathymetric mapping and achievable horizontal and vertical accuracies vary but generally, all SDB outputs are constrained by sensor type, water quality and other environmental conditions. Efforts to improve accuracy include physics-based methods (similar to radiative transfer models e.g. for atmospheric/vegetation studies) or detailed in-situ sampling of the seabed and water column, but the spatial component of SDB measurements is often under-utilised in SDB workflows despite promising results suggesting potential to improve accuracy significantly. In this study, a selection of satellite datasets (Landsat 8, RapidEye and Pleiades) at different spatial and spectral resolutions were tested using a log ratio transform to derive bathymetry in an Atlantic coastal embayment. A series of non-spatial and spatial linear analyses were then conducted and their influence on SDB prediction accuracy was assessed in addition to the significance of each model’s parameters. Landsat 8 (30m pixel size) performed relatively weak with the non-spatial model, but showed the best results with the spatial model. However, the highest spatial resolution imagery used – Pleiades (2m pixel size) showed good results across both non-spatial and spatial models which suggests a suitability for SDB prediction at a higher spatial resolution than the others. In all cases, the spatial models were able to constrain the prediction differences at increased water depths

Tensile and Compressive Mechanical Behaviour of Human Blood Clot Analogues

Endovascular thrombectomy procedures are significantly influenced by the mechanical response of thrombi to the multi-axial loading imposed during retrieval. Compression tests are commonly used to determine compressive ex vivo thrombus and clot analogue stiffness. However, there is a shortage of data in tension. This study compares the tensile and compressive response of clot analogues made from the blood of healthy human donors in a range of compositions. Citrated whole blood was collected from six healthy human donors. Contracted and non-contracted fibrin clots, whole blood clots and clots reconstructed with a range of red blood cell (RBC) volumetric concentrations (5–80%) were prepared under static conditions. Both uniaxial tension and unconfined compression tests were performed using custom-built setups. Approximately linear nominal stress–strain profiles were found under tension, while strong strain-stiffening profiles were observed under compression. Low- and high-strain stiffness values were acquired by applying a linear fit to the initial and final 10% of the nominal stress–strain curves. Tensile stiffness values were approximately 15 times higher than low-strain compressive stiffness and 40 times lower than high-strain compressive stiffness values. Tensile stiffness decreased with an increasing RBC volume in the blood mixture. In contrast, high-strain compressive stiffness values increased from 0 to 10%, followed by a decrease from 20 to 80% RBC volumes. Furthermore, inter-donor differences were observed with up to 50% variation in the stiffness of whole blood clot analogues prepared in the same manner between healthy human donors

A qualitative analysis of nonoffending partners’ experiences and perceptions following a psychoeducational group intervention

The present research is a qualitative study analysing therapeutic letters written by the nonoffending partners of men who have perpetrated child sexual abuse, after completion of a psychoeducational group intervention. It sought to identify themes relating to their experiences post-intervention. Findings indicated that the intervention contributed to women having increased insight into sexual offending, and feeling more confident and empowered. In addition, they displayed an awareness of risk issues, and an intention to play a role in helping to manage their partner’s future risk. Implications for research and clinical practice are discussed
