Bodies of Seeing: A video ethnography of academic x-ray image interpretation training and professional vision in undergraduate radiology and radiography education

This thesis reports on a UK-based video ethnography of academic x-ray image interpretation training across two undergraduate courses in radiology and radiography. By studying the teaching and learning practices of the classroom, I initially explore the professional vision of x-ray image interpretation and how its relation to normal radiographic anatomy founds the practice of being ‘critical’. This criticality accomplishes a faculty of perceptual norms that is coded and organised and also, therefore, of a specific radiological vision. Professionals’ commitment to the cognitivist rhetoric of ‘looking at’/‘pattern recognition’ builds this critical perception, a perception that deepens in organisation when professionals endorse a ‘systematic approach’ that mediates matter-of-fact thoroughness and offers a helpful critical commentary towards the image. In what follows, I explore how x-ray image interpretation is constituted in case presentations. During training, x-ray images are treated with suspicion and as misleading and are aligned with a commitment to discursive contexts of ‘missed abnormality’, ‘interpretive risk’, and ‘technical error’. The image is subsequently constructed as ambiguous and that what is shown cannot be taken at face value. This interconnects with reenacting ideals around ‘seeing clearly’ that are explained through the teaching practices and material world of the academic setting and how, if misinterpretation is established, the ambiguity of the image is reduced by embodied gestures and technoscientific knowledge. By making this correction, the ambiguous image is reenacted and the misinterpretation of image content is explained. To conclude, I highlight how the professional vision of academic x-ray image interpretation prepares students for the workplace, shapes the classificatory interpretation of ab(normal) anatomy, manages ambiguity through embodied expectations and bodily norms, and cultivates body-machine relations

Quantitative analysis of the impacts of Croatia's agricultural trade policy on the agri-food sector

Croatia recently signed several trade liberalisation agreements. The cornerstones of its trade policy are WTO membership, the Stabilisation and Association Agreement with the EU and Croatia's application of membership as well as bilateral free trade agreements within the Stability Pact for South Eastern Europe. The objective of this paper is to quantify the impact of Croatia's agricultural trade policy on the agri-food sector. For the analysis, a partial equilibrium model based on 1999/2000 data is used. Trade between Croatia and Bosnia and Herzegovina, Hungary, Slovenia, the EU-15 and the rest of the world is modelled for 12 product groups. Three liberalisation scenarios are analysed for the years 2002 and 2005. The scenarios differ with regard to the tariff changes. In general, the model results indicate that reciprocal trade liberalisation is welfare improving for Croatia. The increase in consumer welfare is larger than the decline in farmers' profits and the loss of governmental tariff revenues. In conclusion, the continuation of trade liberalisation is to be recommended. However, trade policy alone will not solve the existing problems of the agri-food sector, and transitional compensation measures could be considered to avoid unacceptable hardship. The benefits of trade liberalisation are primarily to be seen in an improved access to international markets, which probably enables Croatian food processors to realise economies of scale. In addition, internationally binding commitments such as trade agreements are likely to foster the internal and international political credibility and reduce political risks. -- G E R M A N V E R S I O N: In den letzten Jahren hat Kroatien mehrere Handelsabkommen unterzeichnet. Die Hauptelemente der kroatischen Handelspolitik sind die Mitgliedschaft in der WTO, das Stabilisierungsund Assoziierungsabkommen mit der EU und der Antrag auf EU-Mitgliedschaft sowie die bilateralen Freihandelsabkommen innerhalb des Stabilitätspaktes für Südosteuropa. Ziel des vorliegenden Beitrages ist es, die Auswirkungen dieser Agrarhandelspolitik auf den kroatischen Agrar- und Ernährungssektor zu quantifizieren. Für die Analyse wird ein partielles Gleichgewichtsmodell verwendet, das auf Daten der Jahre 1999/2000 basiert. Für 12 Produktgruppen wird Kroatiens Handel mit Bosnien und Herzegowina, Ungarn, Slowenien, der EU-15 und dem Rest der Welt modelliert. Für die Jahre 2002 und 2005 werden drei Liberalisierungsszenarien untersucht, die sich bezüglich der Zolländerungen unterscheiden. Insgesamt zeigen die Modellergebnisse, das eine wechselseitige Handelsliberalisierung wohlfahrtssteigernde Effekte für Kroatien hat. Der Anstieg der Konsumentenwohlfahrt übersteigt den Einkommensrückgang der Landwirte und den Verlust an staatlichen Zolleinnahmen. Daher ist eine Fortsetzung der Handelsliberalisierung empfehlenswert. Allerdings kann die Handelspolitik alleine die existierenden Probleme im Agrar- und Ernährungssektor Kroatiens nicht lösen. Um unerwünschteHärten zu vermeiden, könnten für eine Übergangsphase Kompensationsmaßnahmen in Betracht gezogen werden. Der Nutzen einer Handelsliberalisierung ist vor allem in einem verbesserten Zugang zu internationalen Märkten zu sehen. Dies ermöglicht es kroatischen Verarbeitern wahrscheinlich, Skaleneffekte zu realisieren. Außerdem erhöhen international bindende Verpflichtungen wie Handelsabkommen die interne und internationale politische Glaubwürdigkeit und tragen damit dazu bei, politische Risiken zu reduzieren.Croatia,trade liberalisation,agri-food sector,partial equilibrium analysis,Kroatien,Handelsliberalisierung,Agrar- und Ernährungssektor,partielle Gleichgewichtsanalyse

"Controlling conceptions" in management accounting and control research in German speaking countries revisited: Definition of citeria for Controlling conceptions and theses on conceptional management accounting and control research

The construction, analysis, and review of "controlling conceptions" (conceptions regarding the managerial accounting and control function) are important and influental branch as well a characteristic of management accounting and control research in German speaking countries. This discourse contains strong aspects if an identification and justification process for finding the unique position and specific role of controlling in academia and business functions. Still, a widely accepted and sustainable delineation against other business economics and management diciplines has not been accomplished. However, a clear picture of the scientific object is regarded as beneficial for forming and directing research endeavours. This paper aims at structuring the course of the controlling conceptions discourse by presenting criteria for judging the quality of the existing conceptions (theoretic fountdation, precision, consitency, empiracal validity), and applying these to the conceptions. Building on the assumed adequacy of the proposed critera and the thusly extracted shortcomings of the conceptions, five theses are presented, which summarise the requirements on further conceptional controlling research and propose a new direction for these endeavours regarding the scientific object.conceptional management accounting and control research; Germany; Controlling conpections; Controlling theory

Japanese Cost Accounting Systems - analysis of the cost accounting systems of the Japanese cost accounting standard

This paper aims at providing an insight into Japanese cost accounting. Firstly, the development of cost accounting in Japan is delineated. Subsequently, the cost accounting systems codified in the Japanese cost accounting standard are analysed based on the classification according to Hoitsch/Schmitz. Lastly, a critical appraisal of the cost accounting systems of the Japanese cost accounting standard as well as a comparison to German and American cost accounting systems are conducted.Cost Accounting; Kostenrechnung; Japan

Biophysical studies of motions and interactions of membrane proteins

2011 Fall.Includes bibliographical references.We have utilized a variety of biophysical techniques to quantitatively examine the motions and interactions of transmembrane proteins on living cells at the single-molecule level. These include both widefield and confocal optical microscopic methods such as single particle tracking, Förster resonance energy transfer and ratiometric imaging of phase-sensitive probes of lipid order, together with spectroscopic fluctuation methods such as fluorescence correlation spectroscopy and photon counting histogram analysis. Our studies indicate that; 1. Luteinizing hormone receptors on CHO cells and KGN human granulosa cells exhibit restricted lateral diffusion and increased self-association after exposure to human chorianic gonadotropin; 2. In addition to insulin receptor and IGF1 receptor homodimers, rat basophilic leukemia 2H3 cells express significant levels of insulin receptor-IGF1 receptor heterodimers; 3. Clustering of insulin receptors after exposure to insulin on rat basophilic leukemia 2H3 cells is affected by disruption of actin-filaments but not by extraction of membrane cholesterol; 4. Chromium Picolinate and Bis(maltolato)oxovandium(IV) both restrict the lateral diffusion of insulin receptors on rat basophilic leukemia cells and; 5. Individual FcE receptors on rat basophilic leukemia cells exhibit orientation fluctuations on millisecond timescales

Re-assessing Agrarian Policy and Practice in Local Environmental Management: The Case of Beef Cattle

There are policy pressures to make agriculture more environmentally sustainable and to give a more local expression to agri-environmental priorities. This paper considers these moves, with particular reference to the beef sector, and speculates on the further policy responses required to facilitate benign local agri-environmental management. The UK beef sector is characterized by its complexity and diversity but four major systems can be identified operating at varying levels of intensity. Of these, suckler herds and grass-rearing systems have long been associated with high natural value forms of agricultural land management. Many of the cherished habitats and landscapes of the UK are dependent upon grazing for their ecological and amenity value. However a combination of the BSE crisis, the strength of sterling and the recent Foot & Mouth epidemic threatens the sustainability of these high nature value grazing systems. The importance of grazing to fifty selected Sites of Special Scientific Interest is highlighted in the paper. Survey work identified a wide range of systems to be particularly vulnerable to changes in profitability in the beef sector, including: coastal grazing marsh, wet acidic grassland / marshland, upland moor and heath, calcareous grassland and neutral grassland. To maintain these systems requires agricultural policy to be more sensitive to local conditions than appears currently to be the case. There is little policy support for beef farmers in a regional context, still less giving special prominence to those farming within particular biotopes. Nor has there been sufficient policy encouragement to markets for traditional and local beef breeds. The continuing pressure for CAP reform offers further opportunity for policies to be devolved to regions and localities

AlSub: Fully Parallel and Modular Subdivision

In recent years, mesh subdivision---the process of forging smooth free-form surfaces from coarse polygonal meshes---has become an indispensable production instrument. Although subdivision performance is crucial during simulation, animation and rendering, state-of-the-art approaches still rely on serial implementations for complex parts of the subdivision process. Therefore, they often fail to harness the power of modern parallel devices, like the graphics processing unit (GPU), for large parts of the algorithm and must resort to time-consuming serial preprocessing. In this paper, we show that a complete parallelization of the subdivision process for modern architectures is possible. Building on sparse matrix linear algebra, we show how to structure the complete subdivision process into a sequence of algebra operations. By restructuring and grouping these operations, we adapt the process for different use cases, such as regular subdivision of dynamic meshes, uniform subdivision for immutable topology, and feature-adaptive subdivision for efficient rendering of animated models. As the same machinery is used for all use cases, identical subdivision results are achieved in all parts of the production pipeline. As a second contribution, we show how these linear algebra formulations can effectively be translated into efficient GPU kernels. Applying our strategies to $\sqrt{3}$, Loop and Catmull-Clark subdivision shows significant speedups of our approach compared to state-of-the-art solutions, while we completely avoid serial preprocessing.Comment: Changed structure Added content Improved description
