Report of the first meeting of the roundtable consultative group on HIV/AIDS in Luapula fisheries, Zambia

The WorldFish Center organized a roundtable meeting in Mansa, Zambia to provide to provide an opportunity for a wide range of agencies to exchange their knowledge and experiences of working with fishing communities and fish traders in Luapula Province. A total of 28 people participated, from government, NGOs and civil society, 6 of whom traveled from Lusaka. Objectives of the roundtable meeting were 1) To get an overview of agencies and their activities relating to fishing communities in Luapula province; 2) To discuss issues related to health, HIV/AIDS and social development affecting fishing communities in Luapula province; 3) To identify challenges in supporting fishing communities; 4) To discuss areas of potential collaboration in 2009 and beyond.Fisheries, AIDS, Public health, HIV, Nutritive value

To mesh or not to mesh: flexible wireless indoor communication among mobile robots in industrial environments

Mobile robots such as automated guided vehicles become increasingly important in industry as they can greatly increase efficiency. For their operation such robots must rely on wireless communication, typically realized by connecting them to an existing enterprise network. In this paper we motivate that such an approach is not always economically viable or might result in performance issues. Therefore we propose a flexible and configurable mixed architecture that leverages on mesh capabilities whenever appropriate. Through experiments on a wireless testbed for a variety of scenarios, we analyse the impact of roaming, mobility and traffic separation and demonstrate the potential of our approach

Federated Robust Embedded Systems: Concepts and Challenges

The development within the area of embedded systems (ESs) is moving rapidly, not least due to falling costs of computation and communication equipment. It is believed that increased communication opportunities will lead to the future ESs no longer being parts of isolated products, but rather parts of larger communities or federations of ESs, within which information is exchanged for the benefit of all participants. This vision is asserted by a number of interrelated research topics, such as the internet of things, cyber-physical systems, systems of systems, and multi-agent systems. In this work, the focus is primarily on ESs, with their specific real-time and safety requirements. While the vision of interconnected ESs is quite promising, it also brings great challenges to the development of future systems in an efficient, safe, and reliable way. In this work, a pre-study has been carried out in order to gain a better understanding about common concepts and challenges that naturally arise in federations of ESs. The work was organized around a series of workshops, with contributions from both academic participants and industrial partners with a strong experience in ES development. During the workshops, a portfolio of possible ES federation scenarios was collected, and a number of application examples were discussed more thoroughly on different abstraction levels, starting from screening the nature of interactions on the federation level and proceeding down to the implementation details within each ES. These discussions led to a better understanding of what can be expected in the future federated ESs. In this report, the discussed applications are summarized, together with their characteristics, challenges, and necessary solution elements, providing a ground for the future research within the area of communicating ESs

Fiscal federalism : dimensions of tax reform in developing countries

The authors propose four economic principles for use in deciding taxing responsibilities for various levels of government. These are: 1) efficiency of the internal common market - for efficiency in internal common market, taxes on mobile factors and tradable goods should either be assigned to the national government or coordinated among subnational governments; 2) national equity - progressive redistributive taxes ought to be assigned to the level of government having responsibility for redistribution, usually the national government. Subnational governments could levy supplementary flat rates on the federal tax base; 3) administrative costs - to minimize collection, administration, and compliance costs, a tax should be assigned to the level likely to be best informed about its base. This suggests assigning real property taxation to local governments and corporate income taxation to the national government; and 4) fiscal need - to ensure accountability, revenue means should be matched as closely as possible to revenue needs. Thus tax instruments intended to further specific policy objectives should be assigned to the level of government having the responsibility for such a service. Thus progressive redistributive taxes, stabilization instruments, and resource rent taxes would be suitable for assignment to national government; while tolls on intermunicipal roads are suitably assigned to state governments. Some resource taxes, such as royalties and fees and severance taxes on production and/or output, are designed to cover costs of local service provision and could be assigned to subnational governments. In addition, subnational governments could also impose taxes to discourage local environmental degradation. In countries with a federal level VAT, it may be too cumbersome to have subnational sales taxes. In such circumstances, the fiscal need criterion would suggest allowing subnational governments access to taxes which are traditionally regarded as suitable for national administration, such as personal income taxes. The authors also stress the importance of tax harmonization and coordination in preserving internal common market, reducing collection and compliance costs and helping to achieve national equity objectives and suggest methods of achieving such coordination vertically (between the federal and subnational governments) and horizontally (among subnational governments).Municipal Financial Management,Public Sector Economics&Finance,National Governance,Banks&Banking Reform,Environmental Economics&Policies
