Practicing Capitals Across Fields: Extending Bourdieu to Study Inter-Field Dynamics

This essay extends a Bourdieusian perspective on the microfoundations of institutions. Drawing on this perspective, we argue that the recursive dynamics of institutions and action orient actors towards the maintenance of distinct and contradictory practices within, rather than bridging across, different fields. We corroborate our argument with an illustration of how corporate executives strategize within the tax field compared to the philanthropy field. Specifically, we show how actors are simultaneously oriented by different capitals towards apparently contradictory strategies. Our essay provides promising avenues for future research on the microfoundations of institutions, inter-field dynamics, and critical accounting and business ethics studies

Trading risks: The value of relationships, models and face-to-face interaction in the global reinsurance market

Over the past 20 years, the reinsurance industry has experienced three profound forces for change. First, technological change has improved information distribution and strengthened connections between global markets. Second, regulatory emphasis on global equivalence in trading practices has generated pressure for convergence across different marketplaces. Third, the widespread acceptance of vendor property catastrophe models has led to more standardised approaches to the evaluation of reinsurance risks, levelling the playing field for decision-making on at least some classes of business. These changes have intensified competition between reinsurance markets. Reinsurance trading centres in remote geographic locations, such as Bermuda, where it is more difficult to transact business face-to-face, have been able to write risk via electronic communications and now have very significant positions in the global reinsurance market. Simultaneously, Lloyd’s of London, one of the original reinsurance markets that is still very much based on the face-to-face approach, has demonstrated its capability to weather financial shocks and downturns and remains an important player in global reinsurance

Charting new territory for organizational ethnography : Insights from a team-based video ethnography

Purpose: Increasing complexity, fragmentation, mobility, pace, and technological intermediation of organizational life make “being there” increasingly difficult. Where do ethnographers have to be, when, for how long, and with whom to “be there” and grasp the practices, norms, and values that make the situation meaningful to natives? These novel complexities call for new forms of organizational ethnography. The purpose of this paper is to discuss the above issues. Design/methodology/approach: In this paper, the authors respond to these calls for innovative ethnographic methods in two ways. First, the paper reports on the practices and ethnographic experiences of conducting a year-long team-based video ethnography of reinsurance trading in London. Findings: Second, drawing on these experiences, the paper proposes a framework for systematizing new approaches to organizational ethnography and visualizing the ways in which they are “expanding” ethnography as it was traditionally practiced. Originality/value: The paper contributes to the ethnographic literature in three ways: first, the paper develops a framework for charting new approaches to ethnography and highlight its different dimensions – site, instrument, and fieldworker. Second, the paper outlines the opportunities and challenges associated with these expansions, specifically with regard to research design, analytical rigour, and communication of results. Third, drawing on the previous two contributions, the paper highlights configurations of methodological expansions on the aforementioned dimensions that are more promising than others in leveraging new technologies and approaches to claim new territory for organizational ethnography and enhance its relevance for understanding today's multifarious organizational realities

Domain decomposition in shallow lake modelling for operational forecasting of flooding

For the prediction of flooding at the borders of the major lakes in the Netherlands, a new system is in operational use. At the moment the time horizon of forecasts is two days ahead. To enlarge this time horizon, the shallow-water models of the lakes will be applied in combination with short-to-medium weather ensemble forecasts up to 15 days. Therefore, in this paper we study how to run ensembles with these models efficiently on current hardware. For this purpose, we use domain decomposition in the shallow-water models to have a good balance between computational times and (parallel) efficiency

In-situ monitoring for CVD processes

Aiming towards process control of industrial high yield/high volume CVD reactors, the potential of optical sensors as a monitoring tool has been explored. The sensors selected are based on both Fourier transform infrared spectroscopy (FTIR) and tunable diode laser spectroscopy (NIR-DLS). The former has the advantage of wide spectral capability, and well established databases. NIR-DLS spectroscopy has potentially high sensitivity, laser spatial resolution, and the benefits of comparatively easier integration capabilities-including optical fibre compatibility. The proposed technical approach for process control is characterised by a 'chemistry based' feedback system with in-situ optical data as input information. The selected optical sensors continuously analyze the gas phase near the surface of the growing layer. The spectroscopic data has been correlated with process performance and layer properties which, in turn establish data basis for process control. The new process control approach is currently being verified on different industrialised CVD coaters. One of the selected applications deals with the deposition of SnO2 layers on glass based on the oxidation of (CH3)2SnCl2, which is used in high volume production for low-E glazing

Locational memory of macrovessel vascular cells is transcriptionally imprinted

Vascular pathologies show locational predisposition throughout the body; further insights into the transcriptomics basis of this vascular heterogeneity are needed. We analyzed transcriptomes from cultured endothelial cells and vascular smooth muscle cells from nine adult canine macrovessels: the aorta, coronary artery, vena cava, portal vein, femoral artery, femoral vein, saphenous vein, pulmonary vein, and pulmonary artery. We observed that organ-specific expression patterns persist in vitro, indicating that these genes are not regulated by blood flow or surrounding cell types but are likely fixed in the epigenetic memory. We further demonstrated the preserved location-specific expression of GATA4 protein in cultured cells and in the primary adult vessel. On a functional level, arterial and venous endothelial cells differed in vascular network morphology as the arterial networks maintained a higher complexity. Our findings prompt the rethinking of the extrapolation of results from single-origin endothelial cell systems

The course of mental health problems in children presenting with abdominal pain in general practice

Objective. To investigate the course of mental health problems in children presenting to general practice with abdominal pain and to evaluate the extent to which abdominal pain characteristics during follow-up predict the presence of mental health problems at 12 months' follow-up. Design. A prospective cohort study with one-year follow-up. Setting. 53 general practices in the Netherlands, between May 2004 and March 2006. Subjects. 281 children aged 4-17 years. Main outcome measures. The presence of a depressive problem, an anxiety problem, and multiple non-specific somatic symptoms at follow-up and odds ratios of duration, frequency, and severity of abdominal pain with these mental health problems at follow-up. Results. A depressive problem persisted in 24/74 children (32.9%; 95% CI 22.3-44.9%), an anxiety problem in 13/43 (30.2%; 95% CI 17.2-46.1%) and the presence of multiple non-specific somatic symptoms in 75/170 children (44.1%; 95% CI 36.7-51.6%). None of the abdominal pain characteristics predicted a depressive or an anxiety problem at 12 months' follow-up. More moments of moderate to severe abdominal pain predicted the presence of multiple nonspecific somatic symptoms at follow-up. Conclusions. In one-third of the children presenting to general practice for abdominal pain, anxiety and depressive problems persist during one year of follow-up. Characteristics of the abdominal pain during the follow-up period do not predict anxiety or depressive problems after one-year follow-up. We recommend following over time children seen in primary care with abdominal pain
