History and Historiography in Classical Utilitarianism
Get PDFThis first comprehensive account of the utilitarians' historical thought intellectually resituates their conceptions of philosophy and politics, at a time when the past acquired new significances as both a means and object of study. Drawing on published and unpublished writings - and set against the intellectual backdrops of Scottish philosophical history, German and French historicism, romanticism, positivism, and the rise of social science and scientific history - Callum Barrell recovers the depth with which Jeremy Bentham, James Mill, George Grote, and John Stuart Mill thought about history as a site of philosophy and politics. He argues that the utilitarians, contrary to their reputations as ahistorical and even antihistorical thinkers, developed complex frameworks in which to learn from and negotiate the past, inviting us to rethink the foundations of their ideas, as well as their place in - and relationship to - nineteenth-century philosophy and political thought
The effect of cryogenic machining of S2 glass fibre composite on the hole form and dimensional tolerances
Get PDFS2 glass fibre reinforced epoxy composites are widely used in aeronautical applications owing to their excellent strength to weight ratio. Drilling glass fibres can be cumbersome due to their abrasive nature and poor thermal conductivity. Moreover, the use of conventional coolants is not desirable due to contamination and additional costs for cleaning the machine part. An alternative is to use environmentally friendly coolants such as liquid nitrogen (LN2) which have been previously employed in machining metals and composites. The current study investigates the effect of drilling S2 glass fibre composite in a bath of LN2. The study aims to evaluate the effect of spindle speed, feed rate and the presence of cryogenic cooling on the form and dimensional tolerances of the hole (hole size, circularity, cylindricity and perpendicularity). Design of experiments and analysis of variance (ANOVA) were used to determine the contribution of the input parameters on the analysed hole quality metrics. Results indicated that drilling S2 glass fibre in a cryogenic bath increased hole size significantly beyond the nominal hole diameter. The hole circularity and cylindricity were reduced compared to holes drilled under dry condition under all cutting parameters due to enhanced thermal stability during the drilling process. The current study aims to provide the scientific and industrial communities with the necessary knowledge on whether cryogenic bath cooling strategy provides better hole quality output compared to dry drilling and other cryogenic cooling strategies which were previously reported in the open literature
Dynamic expression of brain functional systems disclosed by fine-scale analysis of edge time series
Get PDFFunctional connectivity (FC) describes the statistical dependence between neuronal populations or brain regions in resting-state fMRI studies and is commonly estimated as the Pearson correlation of time courses. Clustering or community detection reveals densely coupled sets of regions constituting resting-state networks or functional systems. These systems manifest most clearly when FC is sampled over longer epochs but appear to fluctuate on shorter timescales. Here, we propose a new approach to reveal temporal fluctuations in neuronal time series. Unwrapping FC signal correlations yields pairwise co-fluctuation time series, one for each node pair or edge, and allows tracking of fine-scale dynamics across the network. Co-fluctuations partition the network, at each time step, into exactly two communities. Sampled over time, the overlay of these bipartitions, a binary decomposition of the original time series, very closely approximates functional connectivity. Bipartitions exhibit characteristic spatiotemporal patterns that are reproducible across participants and imaging runs, capture individual differences, and disclose fine-scale temporal expression of functional systems. Our findings document that functional systems appear transiently and intermittently, and that FC results from the overlay of many variable instances of system expression. Potential applications of this decomposition of functional connectivity into a set of binary patterns are discussed
Interpreting banks’ sustainability initiatives as reputational risk management and mechanisms for coping, re-embedding and rebuilding societal trust
Get PDFPurpose – This paper aims to contribute to a growing literature in sustainable and green banking by exploring the views of senior banking representatives towards the implementation of sustainability initiatives through extensive interview research. The authors explore the extent to which such initiatives are embedded within the banking industry, whether they represent risk management mechanisms and whether they are imbued with reputational risk management rather than a genuine response to ethical societal concerns.
Design/methodology/approach – Qualitative semi-structured interviews were conducted with UK bank managers. The interviewees’ utterances are interpreted through a sociological theoretical lens derived from the study of Giddens and Beck, allowing us to conclude that external initiatives such as the Equator Principles seem to be adopted as re-embedding mechanisms that can rebuild societal trust, as well as representing mechanisms of reputational risk management.
Findings – The analysis suggested that internal sustainability initiatives were interpreted as coping mechanisms whereby bank employees can recreate their protective cocoon, reinstating their ontological security in response to the high consequence risks of climate change and other related systemic factors that create overwhelming feelings of engulfment.
Originality/value – Using Beck’s risk society theory as a theoretical lens through which to interpret the interview data allows a number of concluding comments and suggestions to be made. The findings resonate with earlier research into institutional investors’ attitudes towards climate change that found their engagement and dialogue with companies around climate change issues to be imbued with a risk discourse: their initiatives and actions were dominated by risk management motivations
The evolution of sectarianism
Get PDFHuman cooperation for reasons other than self-interest has long intrigued social scientists leading to a substantial literature in economics. Its complement – sectarianism – has not received closer attention in economics despite its significant impact. Based on a dynamic model, the paper shows that sectarianism can be understood as the outcome of a repeated bargaining process in which sectarian affiliation evolves into a pure coordination signal that attributes economic and political benefits. It demonstrates that such sectarian social contracts co-evolve with the sects’ degree of coerciveness and are self-reinforcing. Sectarian conflict may then not be a result of diverging religious ideologies but is shown to be caused by external manipulations of the signal (e.g. via identity politics), and internal political and economic grievances within a sect that spill over to the inter-sectarian level while adopting a sectarian appearance. Theoretical results are supported by empirical findings from the Middle East
