    The First International Conference on Cultural Attitudes Towards Technology and Communication (CATaC’98), and its affiliated publications, seek to bring together current insights from philosophy, communication theory, and cultural sciences in an interdisciplinary dialogue. The synthesis of disparate scholarly ideas will shed greater light on just how culture impacts on the use and appropriation of new communications technologies. Beyond the individual contributions themselves, some of our most significant insights will emerge as we listen and discuss carefully with one another during the conference itself. As a way of preparing for that discussion, I offer the following overview of the CATaC papers and abstracts, along with a summary of the insights and questions they suggest

    How culture affects ICT diffusion among SMEs in Bangladesh

    Culture is a broad spectrum of behavioural study which has been illuminated differently in different literature. Applying four cultural dimensions, power distance, uncertainty avoidance, in-group collectivism, and Bengali value, with the two fundamental antecedents of TAM, perceived usefulness and ease of use, this study attempts to look at the effects of culture in ICT diffusion among SMEs in Bangladesh. This study applies a mixed method of research approach. Following an in-depth field study which is analysed through NVivo version 9, a descriptive research design is administered to ascertain the joint impact of the study constructs. Structural equation modelling through PLS graph has been used with a cross-sectional dataset of 51 SMEs in Bangladesh collected through a questionnaire survey. The proposed model was assessed with two step procedure of measuring latent variables structural association. Prior to estimating the structural model, psychometric properties of the model, convergent and discriminant validity, were assessed. The structural model estimation results reveal a significant association of power distance and perceived ease of use with SMEs intention to use ICT. The path analysis furthered a significant effect of intention on actual ICT usage behaviour. The study concludes with implications

    A New Consumerism: The influence of social technologies on product design

    Social media has enabled a new style of consumerism. Consumers are no longer passive recipients; instead they are assuming active and participatory roles in product design and production, facilitated by interaction and collaboration in virtual communities. This new participatory culture is blurring the boundaries between the specific roles of designer, consumer and producer, creating entrepreneurial opportunities for designers, and empowering consumers to influence product strategies. Evolving designer-consumer interactions are enabling an enhanced model of co-production, through a value-adding social exchange that is driving changes in consumer behaviour and influencing both product strategies and design practice. The consumer is now a knowledgeable participant, or prosumer, who can contribute to user–centered research through crowd sourcing, collaborate and co-create through open-source or open-innovation platforms, assist creative endeavors by pledging venture capital through crowd funding and advocate the product in blogs and forums. Social media- enabled product implementation strategies working in conjunction with digital production technologies (e.g. additive manufacture), enable consumer-directed adaptive customisation, product personalisation, and self-production, with once passive consumers becoming product produsers. Not only is social media driving unprecedented consumer engagement and significant behavioural change, it is emerging as a major enabler of design entrepreneurship, creating new collaborative opportunities. Innovative processes in design practice are emerging, such as the provision of digital artifacts and customisable product frameworks, rather than standardised manufactured solutions. This paper examines the influence of social media-enabled product strategies on the methodology of the next generation of product designers, and discusses the need for an educational response

    A dual flow bioreactor with controlled mechanical stimulation for cartilage tissue engineering

    Get PDF
    In cartilage tissue engineering bioreactors can create a controlled environment to study chondrocyte behavior under mechanical stimulation or produce chondrogenic grafts of clinically relevant size. Here we present a novel bioreactor, which combines mechanical stimulation with a two compartment system through which nutrients can be supplied solely by diffusion from opposite sides of a tissue engineered construct. This design is based on the hypothesis that creating gradients of nutrients, growth factors and growth factor antagonists can aid in the generation of zonal tissue engineered cartilage. Computational modeling predicted that the design facilitates the creation of a biologically relevant glucose gradient. This was confirmed by quantitative glucose measurements in cartilage explants. In this system it is not only possible to create gradients of nutrients, but also of anabolic or catabolic factors. Therefore, the bioreactor design allows control over nutrient supply and mechanical stimulation useful for in vitro generation of cartilage constructs that can be used for the resurfacing of articulated joints or as a model for studying OA disease progression
