Towards Adaptable and Adaptive Policy-Free Middleware

We believe that to fully support adaptive distributed applications, middleware must itself be adaptable, adaptive and policy-free. In this paper we present a new language-independent adaptable and adaptive policy framework suitable for integration in a wide variety of middleware systems. This framework facilitates the construction of adaptive distributed applications. The framework addresses adaptability through its ability to represent a wide range of specific middleware policies. Adaptiveness is supported by a rich contextual model, through which an application programmer may control precisely how policies should be selected for any particular interaction with the middleware. A contextual pattern mechanism facilitates the succinct expression of both coarse- and fine-grain policy contexts. Policies may be specified and altered dynamically, and may themselves take account of dynamic conditions. The framework contains no hard-wired policies; instead, all policies can be configured.Comment: Submitted to Dependable and Adaptive Distributed Systems Track, ACM SAC 200

Local Government investing: a form of gambling?

Local councils in New South Wales (NSW) have the authority to invest ratepayers’ money that is not currently required for any other purpose by the council. At the end of 2006-07 financial year local councils in New South Wales had invested $590 million dollars in structured financial products such as collateralised debt obligations (CDO). By the end of January 2008, six months later, the market value of these investments dropped$200 million to $390 million. Since then the financial investment market has further significantly reduced with the value of the councils’ investments losing many more millions of dollars. In NSW the state government commissioned a review of the financial exposures of NSW local councils to be undertaken by Michael Cole. The Cole Report published in 2008 found that while acting within the parameters of the Local Government Act (1993), local councils had pursued high return high risk investment strategies. This paper reviews and evaluates how the local councils in NSW, identified by Cole as having a high level of exposure to these forms of investments, have disclosed their financial investments in their 2007-08 financial reports; the type of audit opinion expressed on these reports; and the impact of these investment related losses on the ability of NSW local councils to provide current and future services

Justice and capabilities in the postcolony: Extending Sen to the Jamaican and South African contexts

This article explores briefly the practical as well as theoretical issues that arise when Amartya Sen’s evaluation of justice through the capabilities afforded citizens in a society is applied to postcolonies like Jamaica and South Africa. It argues that the application of the capabilities approach to the circumstances of the postcolony gives rise to the need for an expansion of its purview as the informational focus of Sen’s theory of justice. This is so because of the manner in which domestic as well as external forces and interests function so as to limit in particular the material conditions necessary for freedom and self-actualization in the postcolony. As examples the article engages briefly with the way in which multinationals and multilateral lending agencies in pursuit of their interests have adverse impact upon capabilities in Jamaica and South Africa, affecting in turn the quality of material life, as well as that of democratic governance in both states. In doing so it broaches the important issue of the failure to engage thoroughly with the reality of the limited maneuverability, both at the domestic and also the international levels, that issues from the role of the developing state in the global political economy (as peripheries for the extraction of raw materials, according to Immanuel Wallerstein’s World Systems Theory), which I think haunts the utilization of the capabilities approach to understanding justice and development in the postcolony.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Newly Insured Californians Would Fall by More than 1 Million Under the Affordable Care Act Without the Requirement to Purchase Insurance

Compares the estimated number and percentage of currently uninsured Californians who will be insured by 2019 under the Affordable Care Act with the individual mandate and without. Highlights the need for the mandate to ensure affordable coverage

Achieving Equity by Building a Bridge From Eligible to Enrolled

Calls for multilingual outreach and enrollment efforts to enable Californians of color and those with limited English proficiency to benefit from the Health Benefit Exchange. Recommends targeting high-need groups and strengthening data collection

The future of citizen science: emerging technologies and shifting paradigms

Citizen science creates a nexus between science and education that, when coupled with emerging technologies, expands the frontiers of ecological research and public engagement. Using representative technologies and other examples, we examine the future of citizen science in terms of its research processes, program and participant cultures, and scientific communities. Future citizen‐science projects will likely be influenced by sociocultural issues related to new technologies and will continue to face practical programmatic challenges. We foresee networked, open science and the use of online computer/video gaming as important tools to engage non‐traditional audiences, and offer recommendations to help prepare project managers for impending challenges. A more formalized citizen‐science enterprise, complete with networked organizations, associations, journals, and cyberinfrastructure, will advance scientific research, including ecology, and further public education

Computational Analyses in Support of Sub-scale Diffuser Testing for the A-3 Facility

A unique assessment of acoustic similarity scaling laws and acoustic analogy methodologies in predicting the far-field acoustic signature from a sub-scale altitude rocket test facility at the NASA Stennis Space Center was performed. A directional, point-source similarity analysis was implemented for predicting the acoustic far-field. In this approach, experimental acoustic data obtained from "similar" rocket engine tests were appropriately scaled using key geometric and dynamic parameters. The accuracy of this engineering-level method is discussed by comparing the predictions with acoustic far-field measurements obtained. In addition, a CFD solver was coupled with a Lilley's acoustic analogy formulation to determine the improvement of using a physics-based methodology over an experimental correlation approach. In the current work, steady-state Reynolds-averaged Navier-Stokes calculations were used to model the internal flow of the rocket engine and altitude diffuser. These internal flow simulations provided the necessary realistic input conditions for external plume simulations. The CFD plume simulations were then used to provide the spatial turbulent noise source distributions in the acoustic analogy calculations. Preliminary findings of these studies will be discussed
