The Antinomies of Autonomy: The Social Structures of Stressors in Ireland and Denmark
Autonomy is a core aspect of the labour process, working conditions, and the relationship between working conditions and well-being. Developments in techno-economic capacities, networked production, occupational structures, and organisational flexibility, have altered the dynamics of autonomy. High levels of work autonomy can now present counter-intuitive demands and contradictions which challenge the experience of self-regulation, discretion, and freedom at work - the Antinomies of Autonomy. In negotiating the decisive and interlinked post-industrial work bargains of effort, boundaries, and employment, different antinomies emerge which can present unique forms of stressors. The interrelated dynamics of the autonomy and antinomies within these post-industrial work bargains present difficulties for models linking working conditions and well-being outcomes (Bakker and Demerouti 2007, Karasek 1979, Siegrist 1996). The key mechanisms shaping the impact of work on psychological well-being go beyond the individual and a work 'place'. The thesis thus presents a sociological framework centred on a stressor (Wheaton 1999) - capability (Sen 1999, Hobson 2014) pathway. Employing a comparative case study method, the research draws from in-depth semi-structured interviews with IT workers in Ireland (n=17) and Denmark (n=14) to explore the antinomies, strategies and stressors of autonomous working lives and how they are shaped by different institutional contexts. The interviews involved psychosocial work environment and job related feelings surveys, alongside more detailed discussions of work and employment conditions in IT. The survey data shows an association between high autonomy and high demands for the Irish interviewees but not the Danish, and a surprising lack of feelings of excitement, enthusiasm, and calmness at work.
The qualitative analysis identifies three mutually reinforcing antinomies of autonomy - interdependence, boundarylessness, and fusion - occurring within the
labour process, working conditions, and the employment relationship respectively. The strategies and stressors emerging from these conditions are based on the 'capability sets' available within each institutional context. The analysis shows how Danish interviewees drew on more collective and institutional resources and norms in developing working life strategies. The Irish interviewees described strategies sourced and sustained mainly at the individual level. The thesis illustrates the complex interplay of post-industrial work bargains, the antinomies of autonomy, institutional capabilities, and the social structure of stressors of working life
Denmark, Durkheim, and Decentralization: The Structures and Capabilities of Danish Working Lives
Over the last two decades, a range of reports and cross-sectional surveys of European workers have highlighted Denmark as scoring exceptionally, and consistently, well across several dimensions shaping working life, for example, job quality, work-life balance, discretion and learning, and job satisfaction. This is despite a trend of increasing psychosocial risks of work across Europe. Providing a retrospective interpretation of this exceptionalism, the paper draws on data from 40 expert interviews in Denmark to theoretically map the advantageous institutional components shaping working life in Denmark. Aligning the theories of Émile Durkheim with the capabilities framework, the analysis highlights the role of interdependent collective agreements, which link macro and microwork contexts and generate resources that augment the experience of balance and control within working lif
Efficient planar camera calibration via automatic image selection
This paper details a novel approach to automatically selecting images which improve camera calibration results. An algorithm is presented which identifies calibration images that inherently improve camera parameter estimates based on their geometric configuration or image network geometry. Analysing images in a more intuitive geometric framework allows image networks to be formed based on the relationship between their world to image homographies. Geometrically, it is equivalent to enforcing maximum independence between calibration images, this ensures accuracy and stability when solving the planar calibration equations. A webcam application using the proposed strategy is presented. This demonstrates that careful consideration of image network geometry, which has largely been neglected within the community, can yield more accurate parameter estimates with less images
Interlinked dual-time feedback loops can enhance robustness to stochasticity and persistence of memory.
Multiple interlinked positive feedback loops shape the stimulus responses of various biochemical systems, such as the cell cycle or intracellular Ca2+ release. Recent studies with simplified models have identified two advantages of coupling fast and slow feedback loops. This dual-time structure enables a fast response while enhancing resistances of responses and bistability to stimulus noise. We now find that (1) the dual-time structure similarly confers resistance to internal noise due to molecule number fluctuations, and (2) model variants with altered coupling, which better represent some specific biochemical systems, share all the above advantages. We also develop a similar bistable model with coupling of a fast autoactivation loop to a slow loop. This model\u27s topology was suggested by positive feedback proposed to play a role in long-term synaptic potentiation (LTP). The advantages of fast response and noise resistance are also present in this autoactivation model. Empirically, LTP develops resistance to reversal over approximately 1h . The model suggests this resistance may result from increased amounts of synaptic kinases involved in positive feedback
