    Protein Folding & Self-Organized Criticality

    Get PDF
    Proteins are known to fold into tertiary structures that determine their functionality in living organisms. However, the complex dynamics of protein folding and the way they consistently fold into the same structures is unknown. Self-organized criticality (SOC) has provided a framework for understanding complex systems in various scientific disciplines through scale invariance and the associated fractal power law behavior. In this research, we use a simple hydrophobic-polar lattice-bound computational model to investigate self-organized criticality as a possible mechanism for generating complexity in protein folding

    Challenges and opportunities to develop a smart city: A case study of Gold Coast, Australia

    With the rapid growth of information and communication technologies, there is a growing interest in developing smart cities with a focus on the knowledge economy, use of sensors and mobile technologies to plan and manage cities. The proponents argue that these emerging technologies have potential application in efficiently managing the environment and infrastructure, promoting economic development and actively engaging the public, thus contributing to building safe, healthy, sustainable and resilient cities. However, are there other important elements in addition to technologies which can contribute to the creation of smart cities? What are some of the challenges and opportunities for developing a smart city? This paper aims to answer these questions by developing a conceptual framework for smart cities. The framework is then applied to the city of Gold Coast to identify challenges and opportunities for developing the city into a ‘smart city’. Gold Coast is a popular tourist city of about 600,000 populations in South East Queensland, Australia, at the southern end of the 240km long coastal conurbation that is centred by Brisbane. Recently, IBM has nominated Gold Coast as one of the three cities in Australia for its Smarter Cities Challenge Grant. The grant will provide the Gold Coast City Council with the opportunity to collaborate with a group of experts from IBM to develop strategies for enhancing its ICT arrangements for disaster response capabilities. Gold Coast, meanwhile, has potential to diversify its economy from being centred on tourism to a knowledge economy with focus on its educational institutions, investments in cultural precincts and high quality lifestyle amenities. These provide a unique opportunity for building Gold Coast as an important smart city in the region. As part of the research methodology, the paper will review relevant policies of the council. Finally, lessons will be drawn from the case study for other cities which seek to establish themselves as smart cities

    Master Planned Communities and Governance

    Get PDF
    In the last three decades, a number of master planned communities (MPCs) have been developed in South East Queensland (SEQ) as part of the response to the housing demands of rapid population growth. Developers, state government, local councils and communities play key roles in the production and management of infrastructure and community services in these Masterplanned communities. Alongside rising community expectations regarding quality of services, there is an increasing trend for developers to be involved in either the direct provision of infrastructure, or its funding, with local councils and the state government playing a facilitating role in provision of services alongside their more traditional role of direct provision. It is imperative to understand the governance structures as well as governance challenges of master planned communities at different stages of development. The objectives of this paper are to review governance frameworks and challenges for master planned communities at three critical stages of development: the visioning and planning stage, the implementation stage, and the completion stage. The paper has identified three distinct governance structures of master planned communities – single developer model, principal developer model and government led model. Three case studies from South East Queensland, each being representative of a particular governance structure, are used to evaluate each of the three stages of development with respect to the challenges involved in the provision of infrastructure and services. The paper provides a framework for analysing the relationship between governance structures and the development of master planned communities, focusing on the relationships that exist between institutional stakeholders, and on the potential impacts of the transfer of infrastructure and service provision from private management to community and local control

    Effectiveness of Structured Teaching Program on Menstrual Hygiene among Adolescent School Girls

    Introduction: Adolescent girls face different physical conversions, sexual changes and psychological pressures associated with growth and maturity, menstruation being one of them. Menstruation is still clouded by taboos and socio-cultural restrictions resulting in ignorance of scientific facts and hygienic health practices. Since response to menstruation depends upon awareness and knowledge about issues, menstrual hygiene education has shown to be effective in improving health by developing good knowledge, attitude and practice among adolescent girls. Methods: An analytical study with one group pretest – posttest design was carried out to assess the effectiveness of structured teaching program on menstrual hygiene among 100 adolescent school girls studying in a public school in Palpa. Pretested semi structured questionnaire was used to assess knowledge and practice whereas valid MAQ (Menstrual Attitude Questionnaire) was used for attitude. This was followed by structured teaching program consisting of information on menstruation, myths and hygiene. Then a posttest was conducted after a week to the same respondents. Results: The study resulted in statistically significant improvements (P<0.001) in total knowledge (63% to 66%), attitude (47% to 63%) and practice (43% to 49%) after implementation of the structured teaching program. There was positive correlation between knowledge and attitude scores (r=0.023), attitude and practice scores (r=0.026) and knowledge and practice scores (r=0.183). Conclusion: The structured teaching program is effective in improving knowledge, attitude and practice on menstrual hygiene among adolescent school girls. Thus, adding menstrual hygiene as part of curriculum may break the culture of silence
