Reasoning about Independence in Probabilistic Models of Relational Data

We extend the theory of d-separation to cases in which data instances are not independent and identically distributed. We show that applying the rules of d-separation directly to the structure of probabilistic models of relational data inaccurately infers conditional independence. We introduce relational d-separation, a theory for deriving conditional independence facts from relational models. We provide a new representation, the abstract ground graph, that enables a sound, complete, and computationally efficient method for answering d-separation queries about relational models, and we present empirical results that demonstrate effectiveness.Comment: 61 pages, substantial revisions to formalisms, theory, and related wor

Alcohol, assault and licensed premises in inner-city areas

This report contains eight linked feasibility studies conducted in Cairns during 2010. These exploratory studies examine the complex challenges of compiling and sharing information about incidents of person-to-person violence in a late night entertainment precinct (LNEP). The challenges were methodological as well as logistical and ethical. The studies look at how information can be usefully shared, while preserving the confidentiality of those involved. They also examine how information can be compiled from routinely collected sources with little or no additional resources, and then shared by the agencies that are providing and using the information.Although the studies are linked, they are also stand-alone and so can be published in peer-reviewed literature. Some have already been published, or are ‘in press’ or have been submitted for review. Others require the NDLERF board’s permission to be published as they include data related more directly to policing, or they include information provided by police.The studies are incorporated into the document under section headings. In each section, they are introduced and then presented in their final draft form. The final published form of each paper, however, is likely to be different from the draft because of journal and reviewer requirements. The content, results and implications of each study are discussed in summaries included in each section.Funded by the National Drug Law Enforcement Research Fund, an initiative of the National Drug StrategyAlan R Clough (PhD) School of Public Health, Tropical Medicine and Rehabilitation Sciences James Cook UniversityCharmaine S Hayes-Jonkers (BPsy, BSocSci (Hon1)) James Cook University, Cairns.Edward S Pointing (BPsych) James Cook University, Cairns

Planning for the reuse of redundant defence estate: disposal processes, policy frameworks and development impacts

This paper reviews recent research and other literature concerning the planning and development of redundant defence estate. It concentrates on UK sources but includes reference to material from Europe and the North America were it is relevant for comparative purposes. It introduces the topic by providing a brief review of the recent restructuring of the UK defence estate and then proceeds to examine the various planning policy issues generated by this process; the policy frameworks used to guide it; comparable approaches to surplus land disposal and the appraisal of impacts; and ending the main body of the review with an analyse of the economic, social and environmental impacts of military base closure and redevelopment. It concludes that there is a significant body of work focusing on the reuse and redevelopment of redundant defence estate in the UK and abroad, but that much of this work is based on limited research or on personal experience. One particular weakness of the current literature is that it does not fully reflect the institutional difficulties posed by the disposal process and the day-to-day pressures which MOD personnel have to deal with. In doing this, it also under-emphasises the embedded cultures of individuals and professional groups who are required to operationalise the policies, procedures and practices for planning and redeveloping redundant defence estate

Promoting decentralised and flexible budgets in England: Lessons from the past and future prospects

The UK has traditionally been viewed as a classic example of a unitary state in which central institutions dominate decision making. The recent Labour Government sought to counter this convention through devolution to Scotland, Wales, Northern Ireland and London and administrative decentralization to the English regions. This article examines New Labour’s efforts to promote sub-national policy discretion and fiscal autonomy via the Regional Funding Allocations (RFA) process. Findings are subsequently drawn upon to offer insights into the difficulties the Coalition Government is likely to face in its endeavor to decentralize functions and budgets to local authorities and communities. The paper addresses two central questions (i) Can New Labour’s attempt to promote decentralized and flexible budgets in England be viewed asevidence of a transition to a more fluid, multi-level form of governance? (ii)What lessons can be harnessed from the RFA experience in taking forward the Coalition government’s plans to promote fiscal discretion at the sub-national tier? It concludes that there are deep-rooted barriers in Whitehall that may limitthe freedoms and flexibilities pledged to local government and could undermine efforts to decentralize

‘I Don’t Trust the Phone; It Always Lies’:Trust and Information and Communication Technologies in Tanzanian Micro- and Small Enterprises

Despite its importance in African enterprise, the issue of ¿trust¿ is absent in information and communication technology for development scholarship. This article examines three case study subsectors of the Tanzanian economy to shed light on some of the complexities surrounding the sudden interface between traditional, established communication, and the increasing use of new information and communication technologies (ICTs). It seems from the case studies that, whereas mobile phones are indeed creating new forms of network in the twenty-first century, they are still far from being Africa's dominant form of network as Støvring (2004, 22) contends. The case studies reveal the overlap between social interaction and business in an African economy. Trust emerges as a common theme, and I discuss how important an issue it is in relation to the new form of communication that ICT provides for entrepreneurs in Africa. I suggest that, in relation to ICT in developing countries, trust might at this stage be separated from the more slippery concept of social capital that it is frequently associated with elsewhere. I then reflect on the implications of this for future research into ICT and its business and nonbusiness applications in developing countries. I conclude by suggesting that the need for direct, personal interaction through face-to-face contact¿a traditional pre-ICT aspect of African business culture¿is unlikely to change for some tim

Exploring continuous organisational transformation as a form of network interdependence

In this paper we examine the problematic area of continuous transformation. We conduct our analysis from three theoretical perspectives: the resource based view, social network theory, and stakeholder theory. We found that the continuous transformation can be explained through the concept of Network Interdependence. This paper describes Network Interdependence and develops theoretical propositions from a synthesis of the three theories. Our contribution of Network Interdependence offers fresh insights into managing complex change and offers new ways of looking at organisational transformation
