    Contemporary developments in teaching and learning introductory programming: Towards a research proposal

    Get PDF
    The teaching and learning of introductory programming in tertiary institutions is problematic. Failure rates are high and the inability of students to complete small programming tasks at the completion of introductory units is not unusual. The literature on teaching programming contains many examples of changes in teaching strategies and curricula that have been implemented in an effort to reduce failure rates. This paper analyses contemporary research into the area, and summarises developments in the teaching of introductory programming. It also focuses on areas for future research which will potentially lead to improvements in both the teaching and learning of introductory programming. A graphical representation of the issues from the literature that are covered in the document is provided in the introduction

    The ergonomics of command and control

    Since its inception, just after the Second World War, ergonomics research has paid special attention to the issues surrounding human control of systems. Command and Control environments continue to represent a challenging domain for Ergonomics research. We take a broad view of Command and Control research, to include C2 (Command and Control), C3 (Command, Control and Communication), and C4 (Command, Control, Communication and Computers) as well as human supervisory control paradigms. This special issue of ERGONOMICS aims to present state-of-the-art research into models of team performance, evaluation of novel interaction technologies, case studies, methodologies and theoretical review papers. We are pleased to present papers that detail research on these topics in domains as diverse as the emergency services (e.g., police, fire, and ambulance), civilian applications (e.g., air traffic control, rail networks, and nuclear power) and military applications (e.g., land, sea and air) of command and control. While the domains of application are very diverse, many of the challenges they face share interesting similarities

    Rationalizing Noneconomic Damages: A Health-Utilities Approach

    Get PDF
    Studdert et al examine why making compensation of noneconomic damages in personal-injury litigation more rational and predictable is socially valuable. Noneconomic-damages schedules as an alternative to caps are discussed, several potential approaches to construction of schedules are reviewed, and the use of a health-utilities approach as the most promising model is argued. An empirical analysis that combines health-utilities data created in a previous study with original empirical work is used to demonstrate how key steps in construction of a health-utilities-based schedule for noneconomic damages might proceed

    The integration of postmodern values and rhetorical analysis: A case study

    Get PDF
    Both traditional preaching theory and the listening context of the hearers have undergone radical changes within the last thirty years. Contemporary preachers no longer can assume the authority inherent in their position or preaching methods, and postmodern listeners exhibit the desire for increased diversity and points of view in sermons. This thesis will address these challenges by advancing the notion that attention to rhetorical criticism in the exegesis of biblical texts sheds new light on the nature of preaching in terms of form and function. The resulting multi-vocal and non-hierarchical leadership orientation has application for postmodern audiences. The methodological structure of theological interpretation undergirding this thesis involves four tasks of the hermeneutical cycle adapted from Richard Osmer’s approach. This approach engages in the task of contextual interpretation that connects with both Christian tradition and Scripture, and furthermore leads to the construction of a pragmatic plan for future homiletics. Chapter 1 introduces the problem facing contemporary homileticians: the changed context of preacher and hearer. The chapter advocates that one way forward for preaching involves the use of rhetorical criticism as the exegetical basis for a values-based homiletic, and then finishes with an overview of the thesis chapters. Chapter 2 demonstrates the fourfold task of the hermeneutical cycle by establishing the provenance of the method, critiquing it and grounding the approach of the thesis in the contemporary postmodern setting. Chapter 3 engages in a contextual interpretation of historic shifts in the fields of rhetoric, biblical studies and homiletics, analyzing and evaluating these trends. The chapter concludes by constructing a pragmatic plan for future biblical studies, a rhetorical-critical-narratological methodology that will be applied to the text of Ezekiel. Chapter 4 demonstrates that a contextual interpretation, evaluation and analysis of the New Homiletic results in the formation of a values-based approach to preaching and leadership orientation that is appropriate to postmodernity. Chapter 5 builds upon a contextual interpretation of synchronic and diachronic methodologies and advances a complementary approach to exegesis. The chapter then applies the rhetorical-critical-narratological approach developed in Chapter 3 to the discourse of Ezekiel to establish its contextual and rhetorical situation. The chapter then engages in a close rhetorical-critical-narratological reading of the literary unit of Ezekiel 15. Chapter 6 engages in a contextual interpretation and evaluation of three Ezekiel commentaries and sermons from Ezekiel 15, locating them along the pendulum-like series of shifts identified within Chapter 3. Chapter 7 demonstrates the integration of biblical studies and homiletics with the production of a sample multiple point-of-view sermon based upon the exegesis of Ezekiel conducted in Chapter 5. The chapter critiques the sermon and provides an example of the rhetorical-critical method applied to a discursive genre from 1 Corinthians 4.18-5.13. Chapter 8 concludes the thesis by reviewing the contributions made by the study, proceeds to interpret contextually the challenge of postmodern homiletics, and finishes with recommendations for areas of future studies outside the scope of the thesis

    Evaluating weaknesses of "perceptual-cognitive training" and "brain training" methods in sport: An ecological dynamics critique

    Get PDF
    The recent upsurge in "brain training and perceptual-cognitive training," proposing to improve isolated processes, such as brain function, visual perception, and decision-making, has created significant interest in elite sports practitioners, seeking to create an "edge" for athletes. The claims of these related "performance-enhancing industries" can be considered together as part of a process training approach proposing enhanced cognitive and perceptual skills and brain capacity to support performance in everyday life activities, including sport. For example, the "process training industry" promotes the idea that playing games not only makes you a better player but also makes you smarter, more alert, and a faster learner. In this position paper, we critically evaluate the effectiveness of both types of process training programmes in generalizing transfer to sport performance. These issues are addressed in three stages. First, we evaluate empirical evidence in support of perceptual-cognitive process training and its application to enhancing sport performance. Second, we critically review putative modularized mechanisms underpinning this kind of training, addressing limitations and subsequent problems. Specifically, we consider merits of this highly specific form of training, which focuses on training of isolated processes such as cognitive processes (attention, memory, thinking) and visual perception processes, separately from performance behaviors and actions. We conclude that these approaches may, at best, provide some "general transfer" of underlying processes to specific sport environments, but lack "specificity of transfer" to contextualize actual performance behaviors. A major weakness of process training methods is their focus on enhancing the performance in body "modules" (e.g., eye, brain, memory, anticipatory sub-systems). What is lacking is evidence on how these isolated components are modified and subsequently interact with other process "modules," which are considered to underlie sport performance. Finally, we propose how an ecological dynamics approach, aligned with an embodied framework of cognition undermines the rationale that modularized processes can enhance performance in competitive sport. An ecological dynamics perspective proposes that the body is a complex adaptive system, interacting with performance environments in a functionally integrated manner, emphasizing that the inter-relation between motor processes, cognitive and perceptual functions, and the constraints of a sport task is best understood at the performer-environment scale of analysis

    An anthropological investigation of urban land development : a thesis presented in partial fulfilment of the requirements for the degree of M.A. in Social Anthropology at Massey University

    The impetus for this project came from examples of neighbours' disempowerment in the land and property development process. There is a growing academic consensus that dominant approaches to land development fail to adequately address this issue. NeoMarxist approaches focus on conflict, power, and exploitation, but effectively eliminate the role of the actual developer in exercising power. Case study approaches, on the other hand, have been concerned with conflict and disempowerment, but have focused on specific instances of neighbourhood opposition and resistance. Explanation is often confined to local and national features of the social and geographical environment. These inadequacies pointed to the need to investigate the increasingly significant role that professional, entrepreneurial developers play at the nexus of the contemporary development process. An ethnographic methodology was used to provide a richer understanding of the land and property development process. The principal participants in the study are a set of 'entrepreneurial developers' operating in and around Palmerston North. Interviews, participant observation, and the examination of case studies are employed. This is complemented by an investigation of the Regulatory Procedure, including interviews with Council Officers, and examination of Council case studies. The research also uses interviews with neighbours, and a wide body of material published within the development industry. Planning for the study drew on Giddens' 'Theory of Structuration' (1979,1984) which stresses the interrelationship between the social structures of the development process, and the agency of developers. The research sought to elucidate the dominant forms of action and ideology which development agents acknowledge, and which therefore constitute the action and ideology of the development industry. The interpretation of the empirical data uses three interrelated perspectives: The first, provides a broad, industry-level, perspective on the local development industry. It asks, 'What are the major influences which shape and structure the contemporary development industry?'; The second, examines the level of action. It asks 'What are the actions of most significance to developers?', and 'What forms of conduct constitute the Institutional structures of the Regulatory Procedure?'; The third focuses on ideology. It asks, 'What are the dominant motivations which direct and influence developers' conduct?', and 'How do developers legitimate and rationalise conduct?'. An interesting aspect to the thesis is the extent to which developers share patterns of ideology, not only with each other, but also with a wider business community. Much of this characteristic ideology parallels findings in other ethnographic studies of capitalistic systems. The research highlights the fact that ethnography, and the notion of 'culture', provide an insightful and useful perspective of both the business world, and the study of development

    Perspectives on safety culture

    Overviewing selected elements from the literature, this paper locates the notion of safety culture within its parent concept of organisational culture. A distinction is drawn between functionalist and interpretive perspectives on organisational culture. The terms ‘culture’ and ‘climate’ are clarified as they are typically applied to organisations and to safety. A contrast is drawn between strategic top down and data-driven bottom up approaches to human factors as an illustrative aspect of safety. A safety case study is used to illustrate two measurement approaches. Key issues for future study include valid measurement of safety culture and developing methods to adequately represent mechanisms through which safety culture might influence, and be influenced by, other safety factors

    The Internet as Idea:For a Transcendental Philosophy of Technology

    Get PDF
    This article attempts to render the Internet an object of philosophical consideration. It does so by referring to Kant’s transcendental approach. The argument is that Kant’s “transcendental idealism” is one example of an approach focused on conditions that much contemporary philosophy of technology misunderstands or ignores. Diverse contemporary thinkers are engaged, including Verbeek, Brey, Stiegler, Clark and Chalmers, Feenberg, and Fuchs. The article considers how these thinkers stand in relation to tendencies towards determinism, subjectivism and excessive forms of optimism and pessimism in relation to the Internet. In terms of Kant’s transcendental idealism, I argue that contemporary philosophy of technology does not go far enough in considering the Internet as a “regulative idea.” In terms of broader transcendental approaches, I argue that openness to the transcendental calls into question presuppositions regarding what constitutes an “empirical” object of enquiry, opening philosophy of technology to important new areas of research
