Studies on Rubber Composition as Passive Acoustic Materials in Underwater Electro Acoustic Tranducer Technology and Their aging Characteristic

The research work has been in the area of compounding and characterization of rubbers for use in under water electro acoustic transducers. The study also covers specific material system such as encapsulation materials, baffle material, seal material, etc. Life prediction techniques of under water rubbers in general have been established with reference to more than one functional property. Ranges of passive materials, besides the active sensing material go into the construction of underwater electro acoustic transducers. Reliability of the transducer is critically dependent on these passive materials. Rubbers are a major class of passive materials. The present work concentrates on these materials. Conventional rubbers are inadequate to meet many of the stringent function specific requirements. There exists a large gap of information in the rubber technology of underwater rubbers, particularly relating to underwater electro acoustic transducers. This study is towards filling up the gaps of information in this crucial area. Water intake into rubber is considered as the single most important issue for the long-term performance of rubbers, especially Neoprene. In this study, the cause and effects of a range of parameters affecting the water absorption by diffusion and permeation have been investigated.

Studies on rubber compositions as passive acoustic materials in underwater electro acoustic transducer technology-and their aging characteristics

Rubber has become an indispensable material in Ocean technology. Rubber components play critical roles such as sealing, damping, environmental protection, electrical insulation etc. in most under water engineering applications. Technology driven innovations in electro acoustic transducers and other sophisticated end uses have enabled quantum jump in the quality and reliability of rubber components. Under water electro acoustic transducers use rubbers as a critical material in their construction. Work in this field has lead to highly reliable and high performance materials which has enhanced service life of transducers to the extent of 1015 years. Present work concentrates on these materials. Conventional rubbers are inadequate to meet many of the stringent functional of the requirements. There exists large gap of information in the rubber technology of under water rubbers, particularly in the context of under water electro acoustic transducers. Present study is towards filling up the gaps of information in this crucial area. The research work has been in the area of compounding and characterisation of rubbers for use in under water electro acoustic transducers. The study also covers specific material system such as encapsulation material, baffle material, seal material, etc. Life prediction techniques of under water rubbers in general has been established with reference to more than one functional property. This thesis is divided into 6 chapters.

Wastewater Treatment Project for Palma Soriano, Cuba: Assessment of Cultural and Ecological Conditions

The Palma Project is an experiment in the use of cultural identity as a social trigger to address ecological degradation. The research methodology draws from environmental, social and urban analyses to unveil the best strategy to address the ecological, river restoration and water treatment challenges in Berkeley, California’s “Sister City” in southeast Cuba, Palma Soriano. The objective is to provide a better quality of life and to create new opportunities for the local community to reconnect with natural cycles of water and the cultivation of their own land. The project aim is to promote the strength and capacity of local communities to protect their own environment based upon a master plan, which includes natural wastewater treatment, reforestation, urban agriculture and the facilitation and utilization of a public space bordering the major river which flows by Palma Soriano, the Cauto. This project will contribute and produce healthy water recycling for Palma, provide a potable water source for the city, encourage ecological restoration of the riparian zone of the Cauto, and provide new opportunities for food production. It is designed to preserve the cultural identity of the local community, and to restore the essential balance between the community’s need to sustain both itself and the natural environment.

Overview of an innovative EU-China collaboration in education and research in sustainable built environment

This paper introduces an international collaboration of EU and Asia in education, training and research in the field of sustainable built environment, which attempts to develop a network of practical and intellectual knowledge and training exchange between Chinese and European Universities in the field of sustainable building design and construction. The projects funded by the European Commission Asia Link program, UK Foreign & Commonwealth Office, British Council and the UK Engineering Physical Sciences Council (EPSRC) have been introduced. The projects have significant impacts on promoting sustainable development in built environment in China. The aim of this paper is to share the experiences with those who are interested and searching the ways to collaborate with China in education and research.

Second language listening strategy research: methodological challenges and perspectives

This paper explores methodological issues related to research into second language listening strategies. We argue that a number of central questions regarding research methodology in this line of enquiry are underexamined, and we engage in the discussion of three key methodological questions: (1) To what extent is a verbal report a valid and reliable way of eliciting information about strategies? (2) Should we control for learners' level of linguistic knowledge when examining their listening strategy use? and (3) What are the problems surrounding the analysis of data gained through verbal reports? We discuss each of these three methodological issues within the framework of a research project investigating listening strategies deployed by learners of French in secondary schools in England. Implications from these findings for future research are discussed.

Ethnographic methodologies for construction research: knowing, practice and interventions

Ethnographic methodologies developed in social anthropology and sociology hold considerable promise for addressing practical, problem-based research concerned with the construction site. The extended researcher-engagement characteristic of ethnography reveals rich insights, yet is infrequently used to understand how workplace realities are lived out on construction sites. Moreover, studies that do employ these methods are rarely reported within construction research journals. This paper argues that recent innovations in ethnographic methodologies offer new routes to: posing questions; understanding workplace socialities (i.e. the qualities of the social relationships that develop on construction sites); learning about forms, uses and communication of knowledge on construction sites; and turning these into meaningful recommendations. This argument is supported by examples from an interdisciplinary ethnography concerning migrant workers and communications on UK construction sites. The presented research seeks to understand how construction workers communicate with managers and each other and how they stay safe on site, with the objective of informing site health-and-safety strategies and the production and evaluation of training and other materials.

Persuasive technology and users acceptance of e-commerce: exploring perceived persuasiveness

This paper reviews theories and models of users’ acceptance and use in relation to “persuasive technology”, to justify the need to add consideration of ‘perceived persuasiveness’. We conclude by identifying variables associated with perceived persuasiveness, and highlight important future research directions in this domain.

Achieving and evidencing research 'impact'? Tensions and dilemmas from an ethic of care perspective

While many academics are sceptical about the 'impact agenda', it may offer the potential to re-value feminist and participatory approaches to the co-production of knowledge. Drawing on my experiences of developing a UK Research Excellence Framework (REF) impact case study based on research on young caregiving in the UK, Tanzania and Uganda, I explore the dilemmas and tensions of balancing an ethic of care and participatory praxis with research management demands to evidence 'impact' in the neoliberal academy. The participatory dissemination process enabled young people to identify their support needs, which translated into policy and practice recommendations and in turn, produced 'impact'. It also revealed a paradox of action-oriented research: this approach may bring greater emotional investment of the participants in the project in potentially negative as well as positive ways, resulting in disenchantment that the research did not lead to tangible outcomes at local level. Participatory praxis may also pose ethical dilemmas for researchers who have responsibilities to care for both 'proximate' and 'distant' others. The 'more than research' relationship I developed with practitioners was motivated by my ethic of care rather than by the demands of the audit culture. Furthermore, my research and the impacts cited emerged slowly and incrementally from a series of small grants in an unplanned, serendipitous way at different scales, which may be difficult to fit within institutional audits of 'impact'. Given the growing pressures on academics, it seems ever more important to embody an ethic of care in university settings, as well as in the 'field'. We need to join the call for 'slow scholarship' and advocate a re-valuing of feminist and participatory action research approaches, which may have most impact at local level, in order to achieve meaningful shifts in the impact agenda and more broadly, the academy.

Development, technological change and innovation, Schumpeter and neo-Schumpeterians

This review essay is devoted to a discussion of some central aspects of the Schumpeterian and neo-Schumpeterian approaches to the dynamic processes of development, technological change and innovation. This essay is organised in two parts. In the first, Schumpeter's insightful distinction between circular flow and development is discussed. In the second, some central elements of the neo-Schumpeterian interpretation and extension of Schumpeter's views are critically outlined, special emphasis being placed on some recent attempts to formalize several of his insights on the cyclical dynamics of the processes of technological change and innovation. I should stress that due to space constraints I will focus primarily upon macrotheoretic issues, thus paying only secondary attention to the neo-Schumpeterian literature on the microeconomics of technological change and to the burgeoning empirical developments along those lines.
