Towards an aspect weaving BPEL engine

This position paper proposes the use of dynamic aspects and the visitor design pattern to obtain a highly configurable and extensible BPEL engine. Using these two techniques, the core of this infrastructural software can be customised to meet new requirements and add features such as debugging, execution monitoring, or changing to another Web Service selection policy. Additionally, it can easily be extended to cope with customer-specific BPEL extensions. We propose the use of dynamic aspects not only on the engine itself but also on the workflow in order to tackle the problems of Web Service hot deployment and hot fixes to long running processes. In this way, composing aWeb Service "on-the-fly" means weaving its choreography interface into the workflow

Guidelines For Pursuing and Revealing Data Abstractions

Many data abstraction types, such as networks or set relationships, remain unfamiliar to data workers beyond the visualization research community. We conduct a survey and series of interviews about how people describe their data, either directly or indirectly. We refer to the latter as latent data abstractions. We conduct a Grounded Theory analysis that (1) interprets the extent to which latent data abstractions exist, (2) reveals the far-reaching effects that the interventionist pursuit of such abstractions can have on data workers, (3) describes why and when data workers may resist such explorations, and (4) suggests how to take advantage of opportunities and mitigate risks through transparency about visualization research perspectives and agendas. We then use the themes and codes discovered in the Grounded Theory analysis to develop guidelines for data abstraction in visualization projects. To continue the discussion, we make our dataset open along with a visual interface for further exploration

Proceedings of International Workshop "Global Computing: Programming Environments, Languages, Security and Analysis of Systems"

According to the IST/ FET proactive initiative on GLOBAL COMPUTING, the goal is to obtain techniques (models, frameworks, methods, algorithms) for constructing systems that are flexible, dependable, secure, robust and efficient. The dominant concerns are not those of representing and manipulating data efficiently but rather those of handling the co-ordination and interaction, security, reliability, robustness, failure modes, and control of risk of the entities in the system and the overall design, description and performance of the system itself. Completely different paradigms of computer science may have to be developed to tackle these issues effectively. The research should concentrate on systems having the following characteristics: • The systems are composed of autonomous computational entities where activity is not centrally controlled, either because global control is impossible or impractical, or because the entities are created or controlled by different owners. • The computational entities are mobile, due to the movement of the physical platforms or by movement of the entity from one platform to another. • The configuration varies over time. For instance, the system is open to the introduction of new computational entities and likewise their deletion. The behaviour of the entities may vary over time. • The systems operate with incomplete information about the environment. For instance, information becomes rapidly out of date and mobility requires information about the environment to be discovered. The ultimate goal of the research action is to provide a solid scientific foundation for the design of such systems, and to lay the groundwork for achieving effective principles for building and analysing such systems. This workshop covers the aspects related to languages and programming environments as well as analysis of systems and resources involving 9 projects (AGILE , DART, DEGAS , MIKADO, MRG, MYTHS, PEPITO, PROFUNDIS, SECURE) out of the 13 founded under the initiative. After an year from the start of the projects, the goal of the workshop is to fix the state of the art on the topics covered by the two clusters related to programming environments and analysis of systems as well as to devise strategies and new ideas to profitably continue the research effort towards the overall objective of the initiative. We acknowledge the Dipartimento di Informatica and Tlc of the University of Trento, the Comune di Rovereto, the project DEGAS for partially funding the event and the Events and Meetings Office of the University of Trento for the valuable collaboration

United Nations Development Assistance Framework for Kenya

The United Nations Development Assistance Framework (2014-2018) for Kenya is an expression of the UN's commitment to support the Kenyan people in their self-articulated development aspirations. This UNDAF has been developed according to the principles of UN Delivering as One (DaO), aimed at ensuring Government ownership, demonstrated through UNDAF's full alignment to Government priorities and planning cycles, as well as internal coherence among UN agencies and programmes operating in Kenya. The UNDAF narrative includes five recommended sections: Introduction and Country Context, UNDAF Results, Resource Estimates, Implementation Arrangements, and Monitoring and Evaluation as well as a Results and Resources Annex. Developed under the leadership of the Government, the UNDAF reflects the efforts of all UN agencies working in Kenya and is shaped by the five UNDG programming principles: Human Rights-based approach, gender equality, environmental sustainability, capacity development, and results based management. The UNDAF working groups have developed a truly broad-based Results Framework, in collaboration with Civil Society, donors and other partners. The UNDAF has four Strategic Results Areas: 1) Transformational Governance encompassing Policy and Institutional Frameworks; Democratic Participation and Human Rights; Devolution and Accountability; and Evidence-based Decision-making, 2) Human Capital Development comprised of Education and Learning; Health, including Water, Sanitation and Hygiene (WASH), Environmental Preservation, Food Availability and Nutrition; Multi-sectoral HIV and AIDS Response; and Social Protection, 3) Inclusive and Sustainable Economic Growth, with Improving the Business Environment; Strengthening Productive Sectors and Trade; and Promoting Job Creation, Skills Development and Improved Working Conditions, and 4) Environmental Sustainability, Land Management and Human Security including Policy and Legal Framework Development; and Peace, Community Security and Resilience. The UNDAF Results Areas are aligned with the three Pillars (Political, Social and Economic) of the Government's Vision 2030 transformational agenda

Remote Opportunities: A Rethinking and Retooling

Abstract Introducing technology as a sustainable means of creating, connecting, and collaborating reveals the need to carefully consider subtle aspects of deployment strategies and support in remote regions. In order to comprehensively address both cultural and technical issues for educational infrastructure, we consider two elements to be key: (1) a staged deployment approach, involving both educators and community members, coupled with (2) uniquely designed collaborative Integrated Development Environments (IDEs) to aid constructivism. This paper presents our current experience with these elements in the context of a pilot project for aboriginal communities on the west coast of British Columbia. Currently, these local communities have been working alongside our group for a staged deployment of programs throughout southern Vancouver Island. In our next phase we will be extending this to more remote regions in the north island and coastal regions. By building on a philosophy of CommunityDriven Initiatives for Technology (C-DIT), we hope to secure community involvement in the development and testing of necessary tool support. These tools specifically target IDEs for the development of programming skills, and support our long term goal to help secondary and postsecondary level students appreciate both the process and the art of programming

Early childhood transitions research: A review of concepts, theory, and practice’ Working Paper 48

Chapter 1 begins by outlining developmental concepts which underpin transition themes, in particular those associated with the theories of Jean Piaget and other ‘stage’ theorists. Their ideas are highlighted early on because so much transitions research builds on or reacts to core developmental assumptions. Chapter 1 then introduces socio-cultural perspectives on early childhood transitions. These are distinguished by their focus on how children learn by interacting with their immediate socio-cultural environments (e.g., caregivers, peers). This emphasis has been elaborated by several disciplines within the social sciences and is increasingly mirrored in early child development programmes around the world. Chapter 2 examines the different ways in which transitions are structured, drawing attention to varying logics that can be employed to mark transitions in early childhood. Institutional settings often use biological age as the criterion for readiness. By contrast, sociocultural transitions are often marked through rites of passage, following the cultural and economic reasoning of a given community. Also, around the world children engage in horizontal transitions as they move between different domains of everyday life. Chapter 3 shifts to perspectives on transitions that are informed by systems theories. These are distinguished from socio-cultural approaches by their greater emphasis on the links between individuals, macro social processes and historical changes. These approaches highlight the linkages between children, their communities and global societies and draw attention to the importance of comprehensive programmes that enable children to engage critically with the demands of a changing environment. Chapter 4 focuses on children’s active roles in shaping their transition experiences, with particular attention to the significance of peer group relationships as a moderating influence on transitions. The section then explores research methods that may enable the implementation of children’s right to participation within research and programming in this area. The final chapter discusses the findings of this review, highlighting significant research strengths and gaps of the various approaches presented, followed by a glossary of key transitions concepts discussed in the paper
