    Predicting multidimensional distributive properties of hyperbranched polymer resulting from AB2 polymerization with substitution, cyclization and shielding

    Full text link
    A deterministic mathematical model for the polymerization of hyperbranched molecules accounting for substitution, cyclization, and shielding effect has been developed as a system of nonlinear population balances. The solution obtained by a novel approximation method shows perfect agreement with the analytical solution in limiting cases and provides, for the first time in this class of polymerization problems, full multidimensional results.Comment: 38 pages, 22 figure

    Incorporating Complexity Theory and Feminism into Video Ethnography

    Full text link
    This research uses video firstly as a tool for data collection, and secondly as a method for reflexive sessions that engage both the researcher and clinicians in reflexive viewing of organisational aspects of clinical work. By focusing on empirical data from videoethnographic research in an intensive care unit (ICU) in New South Wales (NSW)1 this paper broadly demonstrates the compatible intertwining of complexity theory, feminist research principles and video-reflexivity

    Body and the senses in spatial experience: the implications of kinesthetic and synesthetic perceptions for design thinking

    Human perception has long been a critical subject of design thinking. While various studies have stressed the link between thinking and acting, particularly in spatial experience, the term "design thinking" seems to disconnect conceptual thinking from physical expression or process. Spatial perception is multimodal and fundamentally bound to the body that is not a mere receptor of sensory stimuli but an active agent engaged with the perceivable environment. The body apprehends the experience in which one's kinesthetic engagement and knowledge play an essential role. Although design disciplines have integrated the abstract, metaphoric, and visual aspects of the body and its movement into conceptual thinking, studies have pointed out that design disciplines have emphasized visuality above the other sensory domains and heavily engaged with the perception of visual configurations, relying on the Gestalt principles. Gestalt psychology must be valued for its attention to a whole. However, the theories of design elements and principles over-empathizing such visuality posit the aesthetics of design mainly as visual value and understate other sensorial and perceptual aspects. Although the visual approach may provide a practical means to represent and communicate ideas, a design process heavily driven by visuality can exhibit weaknesses undermining certain aspects of spatial experience despite the complexity. Grounded in Merleau-Ponty's notion of multisensory perception, this article discusses the relationship between body awareness and spatial perception and its implication for design disciplines concerning built environments. Special attention is given to the concepts of kinesthetic and synesthetic phenomena known as multisensory and cross-sensory, respectively. This discussion integrates the corporeal and spatiotemporal realms of human experience into the discourse of kinesthetic and synesthetic perceptions. Based on the conceptual, theoretical, and precedent analyses, this article proposes three models for design thinking: Synesthetic Translation, Kinesthetic Resonance, and Kinesthetic Engagement. To discuss the concepts rooted in action-based perception and embodied cognition, this study borrows the neurological interpretation of haptic perception, interoception, and proprioception of space. This article suggests how consideration of the kinesthetic or synesthetic body can deepen and challenge the existing models of the perceptual aspects of environmental psychology adopted in design disciplines.Includes bibliographical references

    Legal aspects of open disclosure II: Attitudes of health professionals - Findings from a national survey

    Full text link
    Objective: To assess the attitudes of health care professionals engaged in open disclosure (OD) to the legal risks and protections that surround this activity. Design and participants: National cross-sectional survey of 51 experienced OD practitioners conducted in mid 2009. Main outcome measures: Perceived barriers to OD; awareness of and attitudes towards medicolegal protections; recommendations for reform. Results: The vast majority of participants rated fears about the medicolegal risks (45/51) and inadequate education and training in OD skills (43/51) as major or moderate barriers to OD. A majority (30/51) of participants viewed qualified privilege laws as having limited or no effect on health professionals' willingness to conduct OD, whereas opinion was divided about the effect of apology laws (state laws protecting expressions of regret from subsequent use in legal proceedings). In four states and territories (Western Australia, South Australia, Tasmania and the Northern Territory), a majority of participants were unaware that their own jurisdiction had apology laws that applied to OD. The most frequent recommendations for legal reform to improve OD were strengthening existing protections (23), improving education and awareness of applicable laws (11), fundamental reform of the medical negligence system (8), and better alignment of the activities of certain legal actors (eg, coroners) with OD practice (6). Conclusions: Concerns about both the medicolegal implications of OD and the skills needed to conduct it effectively are prevalent among health professionals at the leading edge of the OD movement in Australia. The ability of current laws to protect against use of this information in legal proceedings is perceived as inadequate

    Towards tolerance. Exploring changes and explaining differences in attitudes towards homosexuality in Europe

    Get PDF
    Across Europe, public attitudes towards lesbian, gay and bisexual (LGB) individuals range from broad tolerance to widespread rejection. Attitudes towards homosexuality are more than mere individual opinions, but form part of the social and political structures which foster or hinder the equality and emancipation of LGB citizens. This report addresses the issues behind today's differences in tolerance. Have attitudes towards homosexuality changed over the past 30 years? Are there European countries where tolerance is increasing, decreasing, or not changing at all? What explains differences in attitudes? Can differences be attributed to levels of income or education, and does religion play a major role? Are tolerant attitudes found in countries with high levels of gender equality?This report shows that Europe is moving towards more tolerance. However, different countries are moving at a very different pace and from very different starting positions. In addition, the biggest changes seem to have taken place between 1990 and 1999 and did not persist into the new millennium. Differences are related to other values, levels of income and income inequality, educational attainment, religious factors, degree of urbanization, EU membership and political systems, and to links with civil society and LGB movements
