    Study made of interaction between sound fields and structural vibrations

    Get PDF
    Study analyzes structural vibrations and the interactions between them and sound fields. It outlines a conceptual framework to analyze the vibrations of systems and their interactions, incorporating the results of earlier studies and establishing a unified basis for continuing research

    The prediction and measurement of sound radiated by structures

    Get PDF
    Theories regarding the radiation of sound are reviewed and the implementation in strategies for explaining or measuring the sound produced by practical strucutres are discussed. Particular attention is given to those aspects that relate to the determination of the relative amounts of sound generated by various parts of a machine or structure, which can be very useful information for noise reduction efforts

    Scaling up social enterprise: strategies taken from early years providers

    Get PDF
    This paper examines the strategies social enterprises can use to scale up their impact. A traditional view has been for growth to occur through setting up new sites owned by a single organisation. This paper examines the range of other alternatives for scaling up social impact ranging from maximising the impact internally (through new activities, and more sites) to growth beyond the confines of the organisation (through social franchises, use of kite marks, training and networks). The paper is based on an analysis of case studies in the early years sector supporting children and families. The following research questions will be addressed: In what ways can social enterprises scale up their operations? What are the challenges entailed in these scaling up processes? The paper concludes by proposing a model to help define the strategies by which organisations can scale up their social impact

    Social entrepreneurship: Entrepreneurship and social value creation

    Get PDF
    Social entrepreneurship has attracted attention from scholars, policy makers and practitioners in developed and developing countries around the world. Much of the early research was devoted to addressing definitional debates and contextual differences and only recently have scholars turned their attention to investigating the relationship between social value creation and opportunity identification and exploitation. The aim of the chapter is three fold. First, we review the rise to prominence of social entrepreneurship and the principal definitional and contextual debates. Second, we summarize the main research findings concerning social value creation and opportunity identification and exploitation. Finally, we identify ten critical topics for advancing social entrepreneurship knowledge and theory development

    Social enterprises as hybrid organizations: a review and research agenda

    Get PDF
    The impacts of the global economic crisis of 2008, the intractable problems of persistent poverty and environmental change have focused attention on organizations that combine enterprise with an embedded social purpose. Scholarly interest in social enterprise (SE) has progressed beyond the early focus on definitions and context to investigate their management and performance. From a review of the SE literature, the authors identify hybridity, the pursuit of the dual mission of financial sustainability and social purpose, as the defining characteristic of SEs.They assess the impact of hybridity on the management of the SE mission, financial resource acquisition and human resource mobilization, and present a framework for understanding the tensions and trade-offs resulting from hybridity. By examining the influence of dual mission and conflicting institutional logics on SE management the authors suggest future research directions for theory development for SE and hybrid organizations more generally
