Organizing the U.S. Health Care Delivery System for High Performance

Analyzes the fragmentation of the healthcare delivery system and makes policy recommendations -- including payment reform, regulatory changes, and infrastructure -- for creating mechanisms to coordinate care across providers and settings

Object-oriented Tools for Distributed Computing

Distributed computing systems are proliferating, owing to the availability of powerful, affordable microcomputers and inexpensive communication networks. A critical problem in developing such systems is getting application programs to interact with one another across a computer network. Remote interprogram connectivity is particularly challenging across heterogeneous environments, where applications run on different kinds of computers and operating systems. NetWorks! (trademark) is an innovative software product that provides an object-oriented messaging solution to these problems. This paper describes the design and functionality of NetWorks! and illustrates how it is being used to build complex distributed applications for NASA and in the commercial sector

A hierarchical distributed control model for coordinating intelligent systems

A hierarchical distributed control (HDC) model for coordinating cooperative problem-solving among intelligent systems is described. The model was implemented using SOCIAL, an innovative object-oriented tool for integrating heterogeneous, distributed software systems. SOCIAL embeds applications in 'wrapper' objects called Agents, which supply predefined capabilities for distributed communication, control, data specification, and translation. The HDC model is realized in SOCIAL as a 'Manager'Agent that coordinates interactions among application Agents. The HDC Manager: indexes the capabilities of application Agents; routes request messages to suitable server Agents; and stores results in a commonly accessible 'Bulletin-Board'. This centralized control model is illustrated in a fault diagnosis application for launch operations support of the Space Shuttle fleet at NASA, Kennedy Space Center

Sustainable funding for the Welsh rural voluntary sector: issues of networks, legitimacy and power

Although the global economic downturn lends urgency to issues of financial sustainability in the voluntary sector, the issue is not new. There is an emerging consensus that voluntary organisations need to pursue financial sustainability through trading and social enterprise activities, government contracts, and a wider grants base. There have been some prominent success stories emerging over the last decade (e.g. Shore 2001, NCVO 2009, Age Concern 2009). This paper however, questions the extent to which these funding strategies may be pursued successfully by rural organisations. There are some significant barriers that remain unacknowledged by those who advocate such approaches. The authors undertook evaluation work for Sustainable Funding Cymru a project sponsored by the Wales Council for Voluntary Action that aimed to develop the funding capacity of voluntary organisations in Wales. Data for this paper derives from case studies, interviews and a focus group of participants in the project who came from voluntary sector charities, nonprofit organisations and social enterprises that deliver a wide range of social and community services. A substantial number of these serve rural communities. A Unique Context The sustainable funding of the Welsh voluntary sector (and especially its rural areas) is set within three important aspects of its contemporary policy context. Firstly, Wales achieved a degree of independence from the centralised UK state in 1997 and established a separate legislature. The enabling legislation required the new government to partner representatives of the voluntary sector to design and implement policy (OPSI 1998). What has emerged, however, is a set of institutional arrangements that focuses more on representative governance than on service delivery partnerships (Entwistle, 2006). Local public authorities remain the primary service providers for local communities although there is a certain amount of contracting out as in England (Bahle 2003). Secondly, whilst traditional funding sources for the voluntary sector have come from donations and individual giving (NCVO 2009), the current trend is toward public sector funding, which is administered centrally. Additionally, Wales has received some £3 billion in development funding from the European Union (EU), which is set to expire in 2013. This that helping voluntary organisations to prepare for post-EU funding is a priority. There are indications that the sector in Wales fares less well compared to other parts of the UK and that it is more dependent on government sources (local, national or EU). These account for nearly 45% of the current funding of the Welsh voluntary sector (National Assembly for Wales, 2008compared with 36% for the entire UK (including Wales) (NCVO, 2009). Thirdly, rural policy in Wales must be viewed in the context of a changing rural economic landscape. Much of Wales is relatively isolated and poorly served by public transport. It has suffered the devastation of its traditional industries. The decline of the coal and steel industries in particular has brought severe hardship to many communities (Chaney 2002). Thus emerging from the evaluation data and a review of the institutional arrangements derived from political-historical context, is a picture of critical challenges and issues for Welsh rural organisations related to the organisation and their representative actors. Developing Theoretical Linkages In order to gain resources, rural voluntary organisations must engage with some highly complex network relationships. They need to interact both vertically within a mandated set of institutional relations and cultivate horizontal relationships both within their own sector and the public sector to be financially sustainable (Entwistle, 2006). Benson (1975) suggests that ways in which organisations manage relationships both this internal network and with their external linkages will impact on their ability to achieve legitimacy and obtain resources. In Wales these partnerships are proving difficult to implement. Negotiating the fierce competition for public service contracts and strong institutional arrangements for local partnerships make it difficult for rural organisations to achieve the legitimacy and power needed to move beyond the established funding resources (Benson 1975). The paper suggests that in the competition for funding, rural organisations in Wales encounter a number of difficulties. Being embedded in their communities means they are constrained by geography. They are unable to compete with larger UK-wide agencies who have more freedom about where they operate. Also their networks become blocked as they are unable to overcome particularistic local power politics. They lack the people, the organisational capacity and infrastructure to identify, mobilise and secure funding. We suggest that national policies often ignore these rural realities and therefore urge strategies for funding sustainability that are very difficult to achieve for the majority of organisations.

Spectrum sharing security and attacks in CRNs: a review

Cognitive Radio plays a major part in communication technology by resolving the shortage of the spectrum through usage of dynamic spectrum access and artificial intelligence characteristics. The element of spectrum sharing in cognitive radio is a fundament al approach in utilising free channels. Cooperatively communicating cognitive radio devices use the common control channel of the cognitive radio medium access control to achieve spectrum sharing. Thus, the common control channel and consequently spectrum sharing security are vital to ensuring security in the subsequent data communication among cognitive radio nodes. In addition to well known security problems in wireless networks, cognitive radio networks introduce new classes of security threats and challenges, such as licensed user emulation attacks in spectrum sensing and misbehaviours in the common control channel transactions, which degrade the overall network operation and performance. This review paper briefly presents the known threats and attacks in wireless networks before it looks into the concept of cognitive radio and its main functionality. The paper then mainly focuses on spectrum sharing security and its related challenges. Since spectrum sharing is enabled through usage of the common control channel, more attention is paid to the security of the common control channel by looking into its security threats as well as protection and detection mechanisms. Finally, the pros and cons as well as the comparisons of different CR - specific security mechanisms are presented with some open research issues and challenges

Stewardship of the evolving scholarly record: from the invisible hand to conscious coordination

The scholarly record is increasingly digital and networked, while at the same time expanding in both the volume and diversity of the material it contains. The long-term future of the scholarly record cannot be effectively secured with traditional stewardship models developed for print materials. This report describes the key features of future stewardship models adapted to the characteristics of a digital, networked scholarly record, and discusses some practical implications of implementing these models. Key highlights include: As the scholarly record continues to evolve, conscious coordination will become an important organizing principle for stewardship models. Past stewardship models were built on an "invisible hand" approach that relied on the uncoordinated, institution-scale efforts of individual academic libraries acting autonomously to maintain local collections. Future stewardship of the evolving scholarly record requires conscious coordination of context, commitments, specialization, and reciprocity. With conscious coordination, local stewardship efforts leverage scale by collecting more of less. Keys to conscious coordination include right-scaling consolidation, cooperation, and community mix. Reducing transaction costs and building trust facilitate conscious coordination. Incentives to participate in cooperative stewardship activities should be linked to broader institutional priorities. The long-term future of the scholarly record in its fullest expression cannot be effectively secured with stewardship strategies designed for print materials. The features of the evolving scholarly record suggest that traditional stewardship strategies, built on an “invisible hand” approach that relies on the uncoordinated, institution-scale efforts of individual academic libraries acting autonomously to maintain local collections, is no longer suitable for collecting, organizing, making available, and preserving the outputs of scholarly inquiry. As the scholarly record continues to evolve, conscious coordination will become an important organizing principle for stewardship models. Conscious coordination calls for stewardship strategies that incorporate a broader awareness of the system-wide stewardship context; declarations of explicit commitments around portions of the local collection; formal divisions of labor within cooperative arrangements; and robust networks for reciprocal access. Stewardship strategies based on conscious coordination involve an acceleration of an already perceptible transition away from relatively autonomous local collections to ones built on networks of cooperation across many organizations, within and outside the traditional cultural heritage community

The Self-Organisation of Strategic Alliances

Strategic alliances form a vital part of today's business environment. The sheer variety of collaborative forms is notable - which include R&D coalitions, marketing and distribution agreements, franchising, co-production agreements, licensing, consortiums and joint ventures. Here we define a strategic alliance as a cooperative agreement between two or more autonomous firms pursuing common objectives or working towards solving common problems through a period of sustained interaction. A distinction is commonly made between 'formal' and 'informal' inter-firm alliances. Informal alliances involve voluntary contact and interaction while in formal alliances cooperation is governed by a contractual agreement. The advantage of formal alliances is the ability to put in place IPR clauses, confidentially agreements and other contractual measures designed to safeguard the firm against knowledge spill-over. However, these measures are costly to instigate and police. By contrast, a key attraction of informal relationships is their low co-ordination costs. Informal know-how trading is relatively simple, uncomplicated and more flexible, and has been observed in a number of industries. A number of factors affecting firms' decisions to cooperate or not cooperate within strategic alliances have been raised in the literature. In this paper we consider three factors in particular: the relative costs of coordinating activity through strategic alliances vis-a-vis the costs of coordinating activity in-house, the degree of uncertainty present in the competitive environment, and the feedback between individual decision-making and industry structure. Whereas discussion of the first two factors is well developed in the strategic alliance literature, the third factor has hitherto only been addressed indirectly. The contribution to this under-researched area represents an important contribution of this paper to the current discourse. In order to focus the discussion, the paper considers the formation of horizontal inter-firm strategic alliances in dynamic product markets. These markets are characterised by rapid rates of technological change, a high degree of market uncertainty, and high rewards (supernormal profits) for successful firms offset by shortening life cycles.Strategic Alliances, Innovation Networks, Self-Organisation
