An Efficient Search Strategy for Aggregation and Discretization of Attributes of Bayesian Networks Using Minimum Description Length

Bayesian networks are convenient graphical expressions for high dimensional probability distributions representing complex relationships between a large number of random variables. They have been employed extensively in areas such as bioinformatics, artificial intelligence, diagnosis, and risk management. The recovery of the structure of a network from data is of prime importance for the purposes of modeling, analysis, and prediction. Most recovery algorithms in the literature assume either discrete of continuous but Gaussian data. For general continuous data, discretization is usually employed but often destroys the very structure one is out to recover. Friedman and Goldszmidt suggest an approach based on the minimum description length principle that chooses a discretization which preserves the information in the original data set, however it is one which is difficult, if not impossible, to implement for even moderately sized networks. In this paper we provide an extremely efficient search strategy which allows one to use the Friedman and Goldszmidt discretization in practice

Currency innovation for sustainable financing of SMEs: context, case study and scalability

The purpose of this paper is to introduce the topic of complementary currencies to the academy engaged in research on corporate responsibility and responsible finance, as well as the broader field of progressive management studies. It responds to the growing awareness that both managers and researchers need to address a systemic challenge of our time, concerning stagnating economies and growing inequality. An underlying cause of that problem is identified as mainstream monetary systems and the implications for inadequate financing of SMEs and microenterprises. The potential of currency innovation, from cryptographic currencies like Bitcoin, to local currencies and then to commercial barter and countertrade are discussed. Given the novelty of these phenomena for management studies in general and corporate responsibility in particular, an interdisciplinary literature review is presented. Then a case study of a complementary currency in an informal settlement in Kenya is presented and implications for the wider adoption of useful new currencies discussed. It concludes therefore that SMEs need certain types of complementary currency more than others and proposes that companies can engage in currencies as part of their corporate responsibility programmes as well as for direct business benefit

From castle to cage: what to do about the housing crisis?

"An Englishman's home is his castle”. The phrase originates from 17th century England, when it referred to the principle of being able to refuse entry to your home. If you are browsing this article from home right now, you might question if that principle is particularly well applied in a time of mass surveillance. But today, when we say a person’s house is their castle it is usually to suggest that it is natural for us to buy a house – particularly if we are British. The implication is that we won’t feel safe and secure, certainly not prosperous, unless we own a home. This emotional connection to home ownership is something that politicians can be keen to connect to. Yet recent evidence shows unrestrained mechanisms for home ownership are actually an enemy of our prosperity

Elegant disruption: how luxury and society can change each-other for good

This paper outlines the contemporary luxury sector, showing it is global, thriving and influential. It shows how creative destruction is typical in most industry sectors, including luxury, and how disruptive innovation by entrepreneurs is key to that process. It proposes that the current time is potentially disruptive for incumbent luxury brands and groups, due to five key trends that are beginning to re-frame the markets that luxury brands sell to. Sustainable luxury entrepreneurs from USA, UK, Philippines, India, Argentina, China and Hong Kong are profiled and described as pursuing “elegant disruption”: a well-designed intervention in markets that both uses and affects aspirations in ways that change patterns of consumption, production or exchange, for a positive societal outcome. The paper reviews the response of mainstream luxury brands to the sustainability agenda, proposing some possible reasons why they appear to be encumbered in embracing this agenda fully. Some of the paradoxes in the notion of “sustainable luxury” are described, in order to draw implications for both the luxury industry and people interested in positive social change. The paper draws upon the authors five years of interaction with the luxury industry on sustainability issues, and is therefore written as a “first person inquiry” and draws upon principles of “appreciative inquiry” in documenting the breakthrough approaches of some sustainable luxury entrepreneurs
