Identifying macro-environmental critical success factors and key areas for improvement to promote public-private partnerships in infrastructure: Indonesia's perspective

Abstract: – The purpose of this paper is to identify macro-environmental critical success factors (CSFs) and key areas for improvement for public-private partnerships (PPP) in infrastructure development, using Indonesia as a case study. , – The methodology includes the definition of CSFs based on the United Nations for Economic and Social Commission for Asia and the Pacific's self-assessment diagnostic tool and a survey on importance and performance attributes, the application of gap analysis (GA) and importance-performance analysis to prioritize areas needing urgent improvements, and the use of inter-rater agreement analysis to examine to what extent the ratings tend to converge on the same conclusions regarding importance and performance. , – Out of 40 possible success factors, a total of 16 are identified as CSFs in the context of Indonesia. GA suggests that no performance ratings exceed importance ratings for the identified CSFs, indicating the need for remedial actions. The factors requiring immediate improvements are all associated with commitments: to policy continuity, financial transparency, and corruption eradication. , – Although the paper discussing a specific country, the proposed approach is replicable and adaptable in different country contexts. Indonesia's experience can also be of value to governments facing similar problems in encouraging private investment in infrastructure. , – The paper contributes to the body of knowledge on PPP in infrastructure development by focussing exclusively on macro-environmental CSFs and Indonesia's PPPs, which are both rarely discussed in the existing literature.

An application of the ES-FEM in solid domain for dynamic analysis of 2D fluid-solid interaction problems

Abstract: An edge-based smoothed finite element method (ES-FEM-T3) using triangular elements was recently proposed to improve the accuracy and convergence rate of the existing standard finite element method (FEM) for the solid mechanics analyses. In this paper, the ES-FEM-T3 is further extended to the dynamic analysis of 2D fluid–solid interaction problems based on the pressure-displacement formulation. In the present coupled method, both solid and fluid domain is discretized by triangular elements. In the fluid domain, the standard FEM is used, while in the solid domain, we use the ES-FEM-T3 in which the gradient smoothing technique based on the smoothing domains associated with the edges of triangles is used to smooth the gradient of displacement. This gradient smoothing technique can provide proper softening effect, and thus improve significantly the solution of coupled system. Some numerical examples have been presented to illustrate the effectiveness of the proposed coupled method compared with some existing methods for 2D fluid–solid interaction problems.

Proceedings of the 2007 international ACM conference on Supporting group work

Abstract: We are pleased to host Group 2007, a conference that combines world-class research contributions with a beautiful conference location. Group 2007 is part of a series of bi-annual high-impact conferences on computer-based systems that have an impact on groups, organizations, and social networks. For the third time, the conference is being held on beautiful Sanibel Island, on the southwest coast of Florida. Group 2007 will foster a discourse on collaborative technology that bridges the fields of Computer-Supported Cooperative Work (CSCW) and Information Systems (IS). Group 2007 brings together researchers and practitioners from different areas working on the development, introduction, management, deployment, and analysis of computer-based collaborative systems. In these proceedings you will find contributions from academia and industry, including 38 papers (full-length contributions) and 9 notes (papers with smaller yet equally innovative contributions) selected from a record number of submissions (132 papers / 25 notes). This year's program will feature topics including theories of cooperative work and analysis of complex work settings, general questions of interactions in groups for working and learning, awareness and sharing support, technical issues, as well as social computing including social tagging and wikis. Beyond papers and notes, we are excited to host the first ever Doctoral Consortium at Group, sponsored by NSF and Microsoft Research. Thirteen PhD students from five different countries have been selected to participate in a full-day workshop with leading experts in the field. Continuing from previous years, Group 2007 is pleased to also offer workshops, posters, and an opening plenary, not to mention lots of fun in the sun.
