Policy interventions and grassroots initiatives: Mismatches in a relocation project in Chennai, India

This article is based on research that took place between 1998 and 2002 in a relocation project in Southern Chennai, India. About 2,640 poor urban households were relocated from the city centre to the project location on the outskirts of the city in the early 1990s. The objectives of the relocation programme, its organisation and the way it was implemented by the local government is described, as well as the role of NGOs in the area. The main focus however is on the initiatives taken by the relocatees in trying to rebuild their lives in the absence of services and employment. It will describe the nature and the direction of these initiatives, their capacity and significance, and how these initiatives are related to the other actors in the area. The extent of coordination between the different actors and an assessment of the manner in which activities could be better coordinated and matched to improve outcomes for the urban poor is discussed

Longitudinal insights on a sites and services resettlement project:The case of Ambedkar Nagar in Chennai, India

Sites and Services (S&amp;S) schemes were popular in resettlement in the Global South, especially between the 1970s and 1990s. Towards the end of the twentieth century they were considered unsuccessful and discontinued. The abandonment of S&amp;S was based on premature evaluations and narrow indicators, with little understanding of the real timeframes of incremental development processes. Yet, literature on the long-term development of S&amp;S is scarce. This article draws on a longitudinal study in a S&amp;S resettlement project in Chennai which was implemented at the beginning of the 1990s. It examines both the physical and social development of the project. Although initially, due to the remote location of the site and related lack of employment opportunities, a substantial number of beneficiaries had left the area during the early years, the long-term insights show that the neighbourhood achieved a desirable physical development. The results also underscore how different types of homeowners and residents enabled the development of various tenure types, including rental space. The paper argues that these developments facilitated social mixing across economic, ethnic, and linguistic groups.</p

FPGA based modular control platform for switched mode power converters

In educational as well as research environments there is a demand for an easy way to prototype switching converters. Several recurring standard tasks like pulse pattern generation, driving controllable switches and analog to digital conversion of physical quantities e.g. current, voltage and temperature, need to be performed. Because these standard tasks interfere with the research focus, a modular control platform for rapid prototyping is highly desirable. In this paper, a system is presented that provides an effective and flexible solution for these requirements

The European Union (EU) has recently established the Floods Directive as a framework for the assessment and management of these risks. The aim of this article is to explore factors that have hampered or stimulated the implementation process of the Floods Directive in the Netherlands, from its establishment in 2007 until January 2013. During this period, the first requirements of the Floods Directive had to be implemented, while the second and third obligations were to be in an advanced stage. Following a literature review of policy implementation theories and a content analysis of the Floods Directive, we have studied the implementation processes in the Dutch part of the Meuse and Rhine-West catchments. Perceptions of interviewees and survey respondents were used to identify influential factors. Our research shows that although the implementation process in the Netherlands is on schedule, it is iterative and complex. Various constraining and stimulating factors, affecting the implementation process, are distinguished. The article concludes with some suggestions for improving the further implementation of the Floods Directive

Knowledge Transfer and Exchange in Work and Health Research

Knowledge transfer and exchange (KTE) is the practice of preparing and disseminating research to those who can use it. The burden of workplace injury and illness can be great affecting workers, workplaces, the medical system, insurance systems and society as a whole. Occupational health and safety is an important aspect of prevention of workplace injury and illness. However prevention activities are varied and may not be based on the best available evidence, being therefore less effective than possible. The overall aim of the thesis is to examine and evaluate KTE activities and the conceptual basis for KTE in work and heath research. Specific objectives include i) providing an overview of the KTE approaches from the literature which target workplace audiences; ii) disseminating and documenting the uptake and use of an evidence-based tool (PE guide) across British Columbia; iii) document and describe the dissemination activities and the KTE experiences of research staff within work and health research organizations; and iv) examine the conceptual basis of the work and health KTE activities. This thesis consists of four manuscripts that describe three studies: a narrative review of the literature summarizing KTE approaches in work and health research, a study exploring the dissemination and use of an evidence-based guide, and a survey study evaluating the KTE activities of work and health researchers. Though different methodologies were employed the three studies used an organizing conceptual framework by Lavis et al. (2003) comprised of five questions: (1) What (information disseminated), (2) To Whom (target audience, and context), (3) By Whom (messengers), (4) How (KTE approach), (5) What effect (outcomes, impact). The review findings suggest a variety of KTE approaches to transfer work and health research knowledge to workplaces. The KTE approaches address various target audiences and workplace contexts related to health and safety and tended to be guided by conceptual frameworks. The evaluation of KTE approaches is challenging and future research should be designed to allow for more rigorous evaluation. The study describing the dissemination and use of an evidence-based tool reveals that respondents felt the greatest barrier to using the tool was a lack of time. However those that did use the guide reported using it for training purposes, sharing it, and integrating the tool into existing programs. In addition, new actions related to tool use included training, defining team responsibilities and suggesting program implementation steps. The dissemination study suggests that when evidence-based tools were used they helped work and health audiences overcome some challenges involved in using evidence in implementing injury reduction programs. The study provided a better understanding about the uptake and use of this type of tool. Work and health researchers reported that KTE activities were important and they felt confident about interactions with knowledge users. Respondents reported engaging in various KTE activities that extended beyond the typical academic approaches of ‘publish and present’. However they reported that processes supporting KTE as well as the promotion and evaluation of research use could be improved. The KTE activities of work and health research staff address the categories of two popular KTE conceptual frameworks. However, only one-third of respondents reported using guidance from conceptual frameworks in practice. Future research should examine whether KTE activities based on conceptual frameworks have greater impact than those that are not so guided. Taken together the chapters provide a comprehensive picture of KTE in work and health research. The findings reveal important common elements of KTE from the literature as well as work and health research staff. The findings also provide some evidence that disseminating an evidence-based tool has impacts on practice. However work and health research staff KTE activities still focus on traditional academic avenues and often lack guidance form conceptual frameworks. Future research is necessary to further evaluate KTE practice in work and health

The Structural Complexity of (Bi0.5Na0.5)TiO3-BaTiO3 as Revealed by Raman Spectroscopy

The structural phase diagram of the Pb-free ferroelectric (Na1/2Bi1/2)1-xBaxTiO3 (NBT-BT), x<0.1, has been explored by Raman spectroscopy at temperatures from 10 to 470 K. The data provide clear evidence for a proposed temperature-independent morphotropic phase boundary at x \approx 0.055. However, there is no evidence for a structural phase transition across T \approx 370 K for x > 0.055, where bulk-property anomalies appear to signal a transition to a nonpolar or antiferroelectric phase. The results identify that the phase above 370 K shows short-range ionic displacements that are identical to those in the long-range-ordered phase below 370 K. These conclusions provide a natural interpretation of the weak piezoelectric response in this system and have important implications for the search for Pb-free piezoelectrics.Comment: 21 pages, 5 figure
