End-to-End Differentiable Proving

We introduce neural networks for end-to-end differentiable proving of queries to knowledge bases by operating on dense vector representations of symbols. These neural networks are constructed recursively by taking inspiration from the backward chaining algorithm as used in Prolog. Specifically, we replace symbolic unification with a differentiable computation on vector representations of symbols using a radial basis function kernel, thereby combining symbolic reasoning with learning subsymbolic vector representations. By using gradient descent, the resulting neural network can be trained to infer facts from a given incomplete knowledge base. It learns to (i) place representations of similar symbols in close proximity in a vector space, (ii) make use of such similarities to prove queries, (iii) induce logical rules, and (iv) use provided and induced logical rules for multi-hop reasoning. We demonstrate that this architecture outperforms ComplEx, a state-of-the-art neural link prediction model, on three out of four benchmark knowledge bases while at the same time inducing interpretable function-free first-order logic rules.Comment: NIPS 2017 camera-ready, NIPS 201

How costumers’ way of life influence the value co-creation

Purpose: This article is a contribution to the understanding of how value arises in wellestablished markets, and under which circumstances actors integrate resources from different service ecosystems to generate value. To understand this phenomenon, it is fundamental to consider which practices are performed by customers to co-create value and how they do so. Design/Methodology/Approach: Using a qualitative approach, the study provides fresh empirical insight into well-established market processes of value creation. After a literature review an ethnographic approach was chosen in order to understand how co-creation processes occur in the empirical setting of an international restaurant chain. Several observations, conversations and semi-structured interviews were undertaken concerning the analysis of the topic under study. Findings: The results show that even in a well-established market, a provider must consider individual customers’ distinct needs, present in their daily practices, to be able to assist them in the value creation process. It is argued that the practice styles are the building blocks for prevailing ways of life that actors assume, according to the context in which they are, to integrate resources. Practical implications: The study includes implications for service providers of a wellfounded market for facilitating value co-creation along with customers and fulfils the need to better understand this phenomenon. Originality/Value: Recent studies call for empirical evidence on co-creation processes in mature markets, accordingly, this study brings an additional understanding on how actors, depending on the context, adopt different ways of life that require unique resources, which activate to achieve what they want, in order to establish room for co-creation.peer-reviewe

Institutional logics, blended and suspended

This paper examines how a new institution, a code of conduct, arises and develops over time. It shows how the process of debate airs competing logics, questions and fails to question assumptions taken for granted, and yet achieves a large degree of legitimacy without having resolved certain core issues. The UK code of corporate governance has been emulated around the world as a model of good practice. By examining in detail one aspect of the debate – the issue over unitary or two-tier boards – the paper shows how the contest of logics leads not just to new, blended or hybrid logics, but also to suspended logics. The process of consultation brings together actors from differing organizational fields and institutional orders, offering an opportunity to create a new field in a different order, with specific lessons for the practice of corporate governance and general lessons for institution-building

‘CEO equals man’: Gender and informal organisational practices in English sport governance

(2019). ‘CEO equals man’: Gender and informal organisational practices in English sport governance. International Review for the Sociology of Sport by Sage Publications Ltd. All rights reserved. It is available at: https://doi.org/10.1177/1012690219865980Despite the benefits of diversity amongst sport leaders increasingly being argued by both researchers and practitioners, English sport governance remains gender-imbalanced at all levels of leadership. Within this article, we aim to explore how informal organisational practices within two established English national governing bodies impact upon gender equity and gender balance within their governance. This is important to raise awareness of the power of informal organisational practices to favour one gender over another. We present findings generated through a multi-method qualitative approach of semi-structured interviews and participant observation. Official documents from the two organisations were also drawn upon to add specific detail or fill information gaps during the collection, analysis and write-up of data. Throughout the article, we draw upon Bourdieu’s theory of practice to focus on the ways in which cultural resources, processes and institutions hold sport leaders within gendered hierarchies of dominance. We found that informal organisational practices contribute to the reinforcement of gendered structures of dominance which privilege (dominant) men and masculinity, and normalise and naturalise the positions of men as leaders. Some examples of resistance against inequitable informal practices were also evident. Drawing upon Bourdieu’s theorising, we highlight that alternative practices must be valued more highly by the organisation than current problematic practices in order for them to become legitimised, habitual and sustainable. We suggest that one way of achieving this is by linking gender-equitable governance to organisational values and performance to provide motivation for organisations to make genuine, sustainable change.Peer reviewe

ISO and Social Standardisation: Uncomfortable compromises in Global Policy-Making

This paper intends to explore the involvement of ISO, the world’s most iconic standard-setting institution, in the field of social responsibility, leading to the publication of the ISO26000 standard in November, 2010. Through several aspects of this experience, an almost decade-long process, I will show how ISO developed a new political structure aimed specifically at creating global policy, originating one the most sophisticated frameworks in existence to consensualise "universal" sociopolitical principles and infuse them with the legitimacy of a "global" technocracy and liberal institutions. Moreover, I will use the latest ISO26000 experience to argue that conceptual and institutional minimalism, which favours "soft" approaches towards global policy-making, paradoxically results from combining a technocratic aim for global compatibility with more participatory decision-making arrangements involving previously excluded socio-political actors. In that sense, ISO’s upgraded participatory mechanisms solved certain deadlocks suffered by previous initiatives only to affront and spark a new round of contradictions and consequences. Thus, I will conclude commenting on the intrinsic relationship between global standards, governance and complexity, and the difficulties of politically articulating programmes with dissimilar functional differentiation

Andrew Carnegie, World Making and the Logic of Contemporary Entrepreneurial Philanthropy

This paper focuses on the relationship between the business and philanthropic endeavours of world-making entrepreneurs; asking why, how and to what ends these individuals seek to extend their reach in society beyond business. We present an original model of entrepreneurial philanthropy which demonstrates how investment in philanthropic projects can yield positive returns in cultural, social and symbolic capital, which in turn may lead to growth in economic capital. The interpretive power of the model is demonstrated through analysis of the career of Andrew Carnegie, whose story, far from reducing to one of earning a fortune then giving it away, is revealed as more complex and more unified. His philanthropy raised his stock within the field of power, extending his influence and helping convert surplus funds into social networks, high social standing and intellectual currency, enabling him to engage in world making on a grand scale
