    This paper theorises personal data more fundamentally and exposes the vulnerability of organisation-controlled personal data. It then reports on the micro-economic model design of a new personal data exchange by designing and creating PPD or person-controlled personal data through a new technological artefact called the Hub-of-all-Things (HAT) and report the build and implementation of the mechanisms, coordination and incentive structures for PPD exchanges

    An analysis of node-based cluster summation rules in the quasicontinuum method

    Get PDF
    We investigate two examples of node-based cluster summation rules that have been proposed for the quasicontinuum (QC) method: a force-based approach and an energy-based approach which is a generalization of the nonlocal QC method. We show that, even for the case of nearest-neighbor interaction in a one-dimensional periodic chain, both of these approaches create large errors that cannot be removed by increasing the cluster size when used with graded and, more generally, nonsmooth meshes. We offer some suggestions for how the accuracy of (cluster) summation rules may be improved

    'La Sposa trionfante' : entertainments for princely marriages in Turin, Mantua and Florence, 1608

    Get PDF
    This thesis is a study of the pageantry and entertainments which took place in 1608 on the occasion of three aristocratic marriages, those of Princesses Margherita and Isabella of Savoy to Francesco Gonzaga of Mantua and Alfonso d'Este of Modena and of Maria Maddalena of Austria to Cosimo II de' Medici of Tuscany. Volume I comprises: a brief survey of the political situation in northern Italy in 1608, including the marriage negotiations between savoy, Mantua and Modena; a discussion of attitudes to women current in the Renaissance as reflected in marriage pageantry; a full account of the pageantry and entertainments celebrating these marriages, drawing on archival material and contemporary published descriptions; a discussion of the interpretation of pageantry, the response of the spectators, and pageantry's value as political propaganda and as a means of promoting and spreading artistic development. Volume II is an edited collection (in Italian and French) of the relevant documents from Italian state archives and full transcriptions of the three principal accounts published in 1608. The thesis concludes that there is a close relationship between political changes and developments in pageantry. The rise of absolutism as the dominant form of government in Italy at the end of the sixteenth century is parallelled by the glorification of the ruler in pageantry. The stability and prosperity of the state come to be identified with the security and strength of the ruler. The thesis offers a new approach to the role of women in Renaissance politics and society through examination of marriage pageantry. Women are represented as counsellors and mediators, rarely taking action, but promoting peace and, through their role as mothers of future heirs, ensuring stability and prosperity in the state

    Strategy, resource orchestration and e-commerce enabled social innovation in rural China

    Get PDF
    E-commerce enabled social innovation is becoming increasingly important as a way of reducing poverty in developing countries and yet has not been studied much by the IS community. We utilize the concept of resource orchestration as a theoretical lens to develop a fit model that explicates how resources are orchestrated under the guidance of either an indigenous, exogenous or collaborative strategy to achieve e-commerce enabled social innovation. The findings show how resources are orchestrated through the following specific resource-focused actions (collaborating, linking and enriching), which are influenced by the types of strategies applied. Our study also identifies different resource portfolios that influence the type of e-commerce enabled social innovation that can be achieved. This research benefits both academics and practitioners by contributing to cumulative theoretical developments related to e-commerce enabled social innovation and the resource orchestration perspective, and by offering corresponding practical insights to achieve fit between strategy, resource orchestration and social innovation

    Process innovation and performance : the role of divergence

    Get PDF
    Process innovation is a key determinant of performance. While extant literature paints a clear picture of the drivers of process innovation, the effect of process innovation on performance has received little attention. This paper contributes to theory building in this important area and examines how divergence of process innovation impacts performance. Divergence concerns the extent to which the observed level of process innovation diverges from the expected level of process innovation. Positive (negative) divergence occurs when the observed level of process innovation is higher (lower) than expected. In turn, we consider how divergence acts as a driver of performance. This approach is useful and important for managers and theory development as it provides insight into situations where a firm may have “too little” or “too much” process innovation. We use survey and archival data from 5,594 firms across 15 countries and find negative divergence to reduce performance under high competitive intensity, whereas positive divergence is detrimental under high environmental uncertainty. Thus, divergence advances understanding as, in contrast with previous work, we do not suggest that more innovation is always better. These findings contribute to understanding the process innovation-performance relationship and has important implications for strategic management research and practice alike

    From penance to repentance : themes of forgiveness in the early English reformation

    Get PDF
    This thesis is an examination of the historical thought of several key English reformers regarding the assimilation or rejection of different aspects of late medieval notions of the sacrament of penance during the Henrician phase of the English Reformation. It is a study primarily concerned with how notions of penance in the theology of these reformers were inherited from patristic, humanist, and continental reformers and how the evangelicals reworked them. While these reformers did not agree on all matters of theology, important points of contact can be found in how they understood the roles of contrition, confession, and satisfaction within a framework that denied the efficacy of human participation in the forgiveness of sins. There are three distinct sections. The two chapters of the first section are concerned with establishing the context of sacramental penance in the sixteenth century. The first chapter identifies distinct phases of the evolution of notions of sacramental penance from the early church through the scholastics, and the second chapter explores the theology of three important influences on the evangelicals—John Wycliffe, Desiderius Erasmus, and Martin Luther—and shows that while their views were unique, they shared important points of connection with the evangelicals in England. The second section consists of the next four chapters, which are dedicated to individual English exiled evangelicals from 1524-1535. Chapter three identifies Tyndale’s unique use of terminology in his redefining of the terms and rearranging of the formula of sacramental penance as he focused on the covenantal language of Christ’s blood as the satisfaction in place of human effort. Chapter four is concerned with Robert Barnes’ notion of the coexistence of contrition and confession, with oral confession occurring after forgiveness has been made. Chapter five details John Frith’s notion of repentance as related to an earthly purgation of sins and a passive, effortless turning from them. Chapter six examines George Joye’s notion of how an effective confession was to be made to God or to man. The third section comprises only one chapter (seven), and it contends that these exiles had significant influence on the later Henrician formularies, and that within them an evangelical notion of confession prevailed, particularly in the relationship of confession and purgatory, but also the understanding of the relationship between sorrow for sin and its forgiveness

    Unexpectedly high piezoelectricity of Sm-doped lead zirconate titanate in the Curie point region

    Get PDF
    Large piezoelectric coefficients in polycrystalline lead zirconate titanate (PZT) are traditionally achieved through compositional design using a combination of chemical substitution with a donor dopant and adjustment of the zirconium to titanium compositional ratio to meet the morphotropic phase boundary (MPB). In this work, a different route to large piezoelectricity is demonstrated. Results reveal unexpectedly high piezoelectric coefficients at elevated temperatures and compositions far from the MPB. At temperatures near the Curie point, doping with 2 at% Sm results in exceptionally large piezoelectric coefficients of up to 915 pm/V. This value is approximately twice those of other donor dopants (e.g., 477 pm/V for Nb and 435 pm/V for La). Structural changes during the phase transitions of Sm-doped PZT show a pseudo-cubic phase forming ≈50 °C below the Curie temperature. Possible origins of these effects are discussed and the high piezoelectricity is posited to be due to extrinsic effects. The enhancement of the mechanism at elevated temperatures is attributed to the coexistence of tetragonal and pseudo-cubic phases, which enables strain accommodation during electromechanical deformation and interphase boundary motion. This work provides insight into possible routes for designing high performance piezoelectrics which are alternatives to traditional methods relying on MPB compositions

    Borrowing from thy neighbour : a European perspective on sovereign debt

    Get PDF
    European capital markets show increasing concern about the extent of sovereign debts and their sustainability. Here we explore some insights that the Overlapping Generations (OLG) framework has to er on such issues. The OLG framework implies, for example, that there is a limit to the amount of debt that may be sustained in a closed economy | with high debt raising interest rates and crowding out capital formation. But capital market integration with less indebted partners allows for a fall in interest rates as a result of borrowing from one's neighbour. Indeed we nd that | in equilibrium | most of the debt of a high indebted country will be transferred to partner countries. Rather like ECB discount policy, our formal analysis is conducted without taking sovereign default risk properly into account, however. We go on to discuss three possible sources of default risk | creditor panic, exogenous interest rate shocks and \over-borrowing" | and we emphasize the need for comparative statics to be complemented by disequilibrium dynamics

    Coproduction in commissioning decisions : is there an association with decision satisfaction for commissioners working in the NHS? A cross-sectional survey 2010/2011

    Get PDF
    Objectives: To undertake an assessment of the association between coproduction and satisfaction with decisions made for local healthcare communities. Design: A coproduction scale was developed and tested to measure individual National Health Service (NHS) commissioners’ satisfaction with commissioning decisions. Setting: 11 English Primary Care Trusts in 2010–2011. Participants: Staff employed at NHS band 7 or above involved in commissioning decisions in the NHS. 345/440 (78%) of participants completed part of all of the survey. Main outcome measure: Reliability and validity of a coproduction scale were assessed using a correlation-based principal component analysis model with direct oblimin rotation. Multilevel modelling was used to predict decision satisfaction. Results: The analysis revealed that coproduction consisted of three principal components: productive discussion, information and dealing with uncertainty. Higher decision satisfaction was associated with smaller decisions, more productive discussion, decisions where information was readily available to use and those where decision-making tools were more often used. Conclusions: The research indicated that coproduction may be an important factor for satisfaction with decision-making in the commissioning of healthcare services

    What were the impacts of the committee on safety for medicines warning and publication of the NICE Guidelines on trends in child and adolescent antidepressant prescribing in primary care? : a population based study

    Get PDF
    Objectives: To assess the impact of both the Committee on Safety of Medicines (CSM) warning (December 2003) and the National Institute for Health and Care Excellence (NICE) guidance (September 2005) on antidepressant prescription rates in children and adolescents within the UK primary care service. Setting: Population based study of primary care antidepressant prescribing using the Clinical Practice Research Datalink (CPRD). Participants: Under-18s presenting to primary care with a depressive disorder or related diagnostic code recorded in the CPRD. Primary outcome measure: Antidepressant prescription rates per month per 100 000 depressed 4–17 year olds. Results: Following the CSM warning, the prior trend towards increased prescribing rates for selective serotonin reuptake inhibitors (SSRIs) in children was significantly reversed (β for change in trend −12.34 (95% CI −18.67 to −6.00, p<0.001)). However, after the publication of the NICE guidelines the prior trend towards increased prescribing resumed for those SSRIs mentioned as potential treatments in the guidance (fluoxetine, citalopram and sertraline) (β for change in trend 11.52 (95% CI 5.32 to 17.73, p<0.001)). Prescribing of other SSRIs and tricyclics remained low. Conclusions: Despite a strong emphasis on psychosocial interventions for child and adolescent depression, it may be that the NICE guidelines inadvertently encouraged further antidepressant prescribing, at least for those SSRIs cited. Although the guidelines gave cautions and caveats for the use of antidepressants, practitioners may have interpreted these recommendations as endorsing their use in young people with depression and related conditions. However, more accurate prevalence trend estimates for depression in this age group, and information on the use of psychosocial interventions would be needed to rule out other reasons underlying this increase in prescribing
