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

Strategic planning as communicative process

This thesis looks at the construction of a strategic plan within a British university (Unico). After a change in leadership, the well-known strategic planning sequence was adopted to set directions according to Unico’s three Missions, followed by the development of respective goals and measures. The evolving strategic content coincided with the development of Unico’s strategic plan. I was able to follow Unico’s planning efforts over 10 months, from first planning meeting to completion of its strategic plan. The main data source provided non-participant observation (n = 25) and ten versions of Unico’s strategic plan. Additionally, seventy-six interviews were held with participants at various points. In order to examine the strategic plan’s construction, I reconceptualised strategic planning as a communicative process consisting of oral talk and written text. Through this interplay strategic planning activities come in to being. Such reconceptualisation provided a conceptual framework to study the in situ interactions without neglecting contextual characteristics embedding the communicative process. Strategic plans are currently seen as promoting inflexibility and reinforcing the institutional nature of formal strategic planning. Adopting dialogism, as advocated by Bakhtin and Ricoeur, this research provides novel insights into the dialogic of strategy talk and strategy text, such as a strategic plan. Findings illustrated that a strategic plan production cycle provided a meaning making platform for its participants. Through recurrently amending the plan, its content became increasingly specific while at the same time reflecting agreed terminology. This thesis offers an alternative view on strategic planning, elaborates on the strategy-as-practice perspective, focusing on the under-explored area of individuals’ interactions at the micro level, and elaborates on the dialogic of text and agency/conversation, distinguishing between talk and text

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

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

Characteristics and outcomes of patients requiring rapid response system activation within 24 hours of emergency admission

Objectives:&nbsp;To establish the prevalence of emergency responses for clinical deterioration (cardiac arrest team or medical emergency team [MET] activation) within 24 hours of emergency admission, and determine if there were differences in characteristics and outcomes of ward patients whose emergency response was within, or beyond, 24 hours of emergency admission. Design, setting and participants: A retrospective, descriptive, exploratory study using MET, cardiac arrest, emergency department and inpatient databases, set in a 365-bed urban district hospital in Melbourne, Australia. Participants were adult hospital inpatients admitted to a medical or surgical ward via the emergency department (ED) who needed an emergency response for clinical deterioration during 2012. Main outcome measures: Inhospital mortality, unplanned intensive care unit admission and hospital length of stay (LOS). Results: A total of 819 patients needed an emergency response for clinical deterioration: 587 patients were admitted via the ED and 28.4% of emergency responses occurred within 24 hours of emergency admission. Patients whose first emergency response was within 24 hours of emergency admission (compared with beyond 24 hours) were more likely to be triaged to Australasian triage scale category 1 (5.4% v 1.2%, P=0.005), less likely to require ICU admission after the emergency response (7.6% v 13.9%, P=0.039), less likely to have recurrent emergency responses during their hospital stay (9.7% v 34%, P &lt; 0.001) and had a shorter median hospital LOS (7 days v 11 days, P &lt; 0.001). Conclusions: One-quarter of emergency responses after admission via the ED occurred within 24 hours. Further research is needed to understand the predictors of deterioration in patients needing emergency admission.</div

COMMD1-deficient dogs accumulate copper in hepatocytes and provide a good model for chronic hepatitis and fibrosis

New therapeutic concepts developed in rodent models should ideally be evaluated in large animal models prior to human clinical application. COMMD1-deficiency in dogs leads to hepatic copper accumulation and chronic hepatitis representing a Wilson's disease like phenotype. Detailed understanding of the pathogenesis and time course of this animal model is required to test its feasibility as a large animal model for chronic hepatitis. In addition to mouse models, true longitudinal studies are possible due to the size of these dogs permitting detailed analysis of the sequence of events from initial insult to final cirrhosis. Therefore, liver biopsies were taken each half year from five new born COMMD1-deficient dogs over a period of 42 months. Biopsies were used for H&E, reticulin, and rubeanic acid (copper) staining. Immunohistochemistry was performed on hepatic stellate cell (HSC) activation marker (alpha-smooth muscle actin, α-SMA), proliferation (Ki67), apoptosis (caspase-3), and bile duct and liver progenitor cell (LPC) markers keratin (K) 19 and 7. Quantitative RT-PCR and Western Blots were performed on gene products involved in the regenerative and fibrotic pathways. Maximum copper accumulation was reached at 12 months of age, which coincided with the first signs of hepatitis. HSCs were activated (α-SMA) from 18 months onwards, with increasing reticulin deposition and hepatocytic proliferation in later stages. Hepatitis and caspase-3 activity (first noticed at 18 months) increased over time. Both HGF and TGF-β1 gene expression peaked at 24 months, and thereafter decreased gradually. Both STAT3 and c-MET showed an increased time-dependent activation. Smad2/3 phosphorylation, indicative for fibrogenesis, was present at all time-points. COMMD1-deficient dogs develop chronic liver disease and cirrhosis comparable to human chronic hepatitis, although at much higher pace. Therefore they represent a genetically-defined large animal model to test clinical applicability of new therapeutics developed in rodent models

Agreeing on what? creating joint accounts of strategic change

This paper addresses a fundamental conundrum at the heart of meaning-making: how are multiple meanings accommodated within a joint account, given the plurivocal nature of organizations? While a new strategic initiative introduces new meanings that must coexist within multiple prevailing meanings; studies on meaning-making processes place different emphases on the accommodation of such multiplicity within a joint account. Based on the findings from a longitudinal case study conducted in a university setting, we develop a framework that demonstrates two patterns of meaning-making on the basis of distinct micro processes of expanding, combining and reframing that are involved in the accomplishment of a joint account. Our study offers counter-intuitive insights into the way vested interests enable or constrain the construction of a joint account of meaning. In doing so, we contribute to knowledge about resistance, ambiguity and the role of agreement, or lack of agreement in constructing joint accounts within a plurivocal context

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

Cellulose Nanofibril Hydrogel Promotes Hepatic Differentiation of Human Liver Organoids

To replicate functional liver tissue in vitro for drug testing or transplantation, 3D tissue engineering requires representative cell models as well as scaffolds that not only promote tissue production but also are applicable in a clinical setting. Recently, adult liver-derived liver organoids are found to be of much interest due to their genetic stability, expansion potential, and ability to differentiate toward a hepatocyte-like fate. The current standard for culturing these organoids is a basement membrane hydrogel like Matrigel (MG), which is derived from murine tumor material and apart from its variability and high costs, possesses an undefined composition and is therefore not clinically applicable. Here, a cellulose nanofibril (CNF) hydrogel is investigated with regard to its potential to serve as an alternative clinical grade scaffold to differentiate liver organoids. The re
