Optimization flow control -- I: Basic algorithm and convergence

We propose an optimization approach to flow control where the objective is to maximize the aggregate source utility over their transmission rates. We view network links and sources as processors of a distributed computation system to solve the dual problem using a gradient projection algorithm. In this system, sources select transmission rates that maximize their own benefits, utility minus bandwidth cost, and network links adjust bandwidth prices to coordinate the sources' decisions. We allow feedback delays to be different, substantial, and time varying, and links and sources to update at different times and with different frequencies. We provide asynchronous distributed algorithms and prove their convergence in a static environment. We present measurements obtained from a preliminary prototype to illustrate the convergence of the algorithm in a slowly time-varying environment. We discuss its fairness property

Scottish railway policy : past, present - and future?

The major thrust of this briefing paper is to evaluate current and past railwaypolicy and to outline proposals which can overcome previous policy failures. Muchof the discussion on railway policy has involved little more than posturing by themain political parties. Despite protestations to the contrary, their actual policies when in power have been remarkably similar. It is argued here that much of the contentious nature of the debate over railway policy can be resolved by a reappraisal of some fundamental economic attributes of railway services. On the basis of this reappraisal, suggestions are made for the possible restructuring of railway services and the implications of such proposals for Scottish railway services are explored

An enhanced random early marking algorithm for Internet flow control

We propose earlier an optimization based flow control for the Internet called Random Early Marking (REM). In this paper we propose and evaluate an enhancement that attempts to speed up the convergence of REM in the face of large feedback delays. REM can be regarded as an implementation of an optimization algorithm in a distributed network. The basic idea is to treat the optimization algorithm as a discrete time system and apply linear control techniques to stabilize its transient. We show that the modified algorithm is stable globally and converges exponentially locally. This algorithm translates into an enhanced REM scheme and we illustrate the performance improvement through simulation

The emergence of an accounting practice:The fabrication of a government accrual accounting system

Purpose The purpose of this paper is to add to our understanding of the nature of accrual accounting by examining the process involved in its construction, as a dynamic and controversial process. This paper reveals how it is built and constantly modified, reinforced or negated during the process of implementation. Design/methodology/approach This paper’s focus on a government initiative with multiple actors present in the laboratory. Specifically, this study offers a close examination of the day-to-day activities of a laboratory case study; it focuses on participant observation in video conference calls. The discussions held by the project teams are analyzed to extend our inquiry into the most intimate aspects of fact construction (Latour and Woolgar, 1979). These excerpts illustrate the processes of accrual accounting construction and open up the possibility of studying the emergence of accrual accounting through the lens of an action net. Findings The evidence collected reveals the absence of a well-defined template for implementing accrual accounting in government. These results reveal an elaborate process of improvisation and fabrication in the design of this accounting system and a fragile network in action. Originality/value Prior research on accrual accounting in government focuses on the examination of existing accrual accounting systems with somewhat puzzling results on lack of use. In this study, the perspective has been shifted from focusing on accrual accounting as self-evident (Lapsley et al., 2009) to examine its construction. This paper examines this tension between the apparent certainties as espoused by practitioners and the problematic nature of accrual accounting in government. It extends our knowledge of “black box accrual accounting,” and shows that it is a fluid object with significant discretion in the determination of practice. </jats:sec

"Kia Mauri Tau!" Narratives of recovery from disabling mental health problems

A bicultural research team at the University of Waikato successfully applied for funding from the Health Research Council to do a qualitative research project in the area of ‘pathways to wellness’. The Mental Health Narratives Project set out to gather forty narratives of mental ill health, recovery and life after recovery by interviewing Maori and non-Maori women and men who once had a disabling mental health problem. We aimed to describe journeys to mental health, identify key themes in accounts of the recovery process and describe the impact of the experience of mental ill health on life after recovery

The significance of insecure attachment and disorganization in the development of children's externalizing behavior: A meta-analytic study

This study addresses the extent to which insecure and disorganized attachments increase risk for externalizing problems using meta-analysis. From 69 samples (N = 5,947), the association between insecurity and externalizing problems was significant, d = 0.31 (95% CI: 0.23, 0.40). Larger effects were found for boys (d = 0.35), clinical samples (d = 0.49), and from observation-based outcome assessments (d = 0.58). Larger effects were found for attachment assessments other than the Strange Situation. Overall, disorganized children appeared at elevated risk (d = 0.34, 95% CI: 0.18, 0.50), with weaker effects for avoidance (d = 0.12, 95% CI: 0.03, 0.21) and resistance (d = 0.11, 95% CI: −0.04, 0.26). The results are discussed in terms of the potential significance of attachment for mental health

Innovations in Public Services

This is the author accepted manuscript. The final version is available from Emerald via the DOI in this record.The primary focus of this special issue is on the role of accounting in framing and shaping the everyday experiences of citizens, managers and policy makers in public services’ delivery. The role of accountants in such settings has grown significantly over recent decades; indeed, today’s accountants embody one of the central forms of expertise shaping management practices, organisational processes and regulatory mechanisms in multiple organisational settings. Equally, the potential impact of accounting, and calculative practices more generally, has an increasingly extensive reach. There is substantial evidence of the influence of accounting work in, for instance, central and local government, hospitals, higher and further education. Such influence within the sphere of the State and beyond, continues despite debates over the status of professional accounting expertise and critiques of the provenance, uniqueness and usefulness of accounting. This special issue offers a collection of papers which extend our understandings of the intermingling of accounting practices and bureaucratic procedures, in the context of reforms to and within public service organisations. This is a research arena which may yield rich insights into the role of accountants and calculative practices in the shaping of social and economic life. We would like to thank all the authors who have contributed to this special issue, and the reviewers who have kindly offered their valuable time and expertise to challenge and improve the papers

Tomorrow's Doctors: Review of The Australian Medical Workforce Advisory Committee (AMWAC)

The aim of this Review, prepared under the auspices of the Australian Health Ministers' Advisory Council, is to 1. Assess AMWAC's performance to date against its original terms of reference and assess to what extent have expectations been achieved? 2. Assess and make relevant recommendations on future national medical workforce planning needs, taking account of the relationship between the medical workforce and other health professionals and support staff, and AHMAC's decision to establish the Australian Health Workforce Advisory Committee (AHWAC); and the relationship between workforce and broader health systems issues. 3. Assess and make relevant recommendations on the suitability of AMWAC - including its structure and methodology - for meeting future medical workforce planning needs, taking account of access to and utilisation of evidence-based data; need for independence and access to broadly sourced advice; international experiences; and current issues, including the changing medical workforce; the implications of the application of the Trade Practices Act 1974 and competition policy; and corporatisation of medical practice. 4. Consider and recommend on appropriate financial commitment by AHMAC to medical workforce planning
