In this paper, I offer a strong criticism of Giorgio Agamben’s recent political texts. I argue that these texts bring to fruition a larger, contentious trend in the theoretical academy coupling one-dimensional, pessimistic accounts of modernity with strands of messianism. Since the political prospects of messianism, as Agamben’s analyses show, are very thin indeed, I reflectively question the presuppositions that lead him to this prescriptive juncture. In Part I, recurring to Scholem’s classic analyses of Jewish messianism, I show how Agamben’s messianism borrows more or less directly (in The Open) from kabalistic, antinomian, utopian messianism. Having established this exegetical point, I argue two theses in parts II and III. The first, specifically theoretical thesis is that Agamben is driven into his political messianism by the transcendental logic of his analyses of ‘the political’, one which by its nature occludes meaningfully political distinctions by instead seeking out their ontological grounds. The second, specifically political thesis is that the widespread embrace of ontological messianism by thinkers in the post-Marxian academy is a symptom of, rather than a cure for, the wider malaise of the political left in the first world. If critical theory is serious about engaging with progressive praxis, one thing it must do is recall the difference between politics and prima philosophia, so that it does not continue to seek out ‘redemption’ – or at least an apology – in the bowels of the latter.

The concept of "the national interest" has been widely analysed by historians and political scientists. However, there has not been a systematic investigation of the term from the range of theoretical perspectives which comprise the discipline of International Relations. This dissertation fills this gap by examining how the term is variously understood by realist, Marxist, anarchist, liberal, rationalist and constructivist theories of International Relations. It is argued that far from having a clear and unambiguous meaning, "the national interest" is a problematic term which is largely devoid of substantive content.

Examines the graduated paths of Mah ȳn̄a and Vajrayn̄a Buddhism and the instantaneous paths of Ch'an/Zen, rDzogs chen and Mahm̄udr.̄ The main contention between these approaches relates to how the mental defilements are to be purified and how the positive qualities of Buddhahood are to be realised. After comparing and examining the paths it is argued that the polarisation of the "sudden" and "gradual" approaches is the result of the critical philosophies of late Indian and Tibetan Buddhism, rather than a real spiritual dilemma for adherents of either path.

This article examines the link between macroeconomic variables and equity returns in Australia by testing conditional asset pricing models. We find that conditioning the Fama-French model with a series of macroeconomic variables does not considerably improve its performance. However, we do find that the Fama-French factors, SMB and HML, retain their ability to explain equity returns even after the model is conditioned on macroeconomic variables. Our findings suggest that investors do not adjust their risk premiums according to the changes in the macroeconomic variables we employ.

There is strong rationale for improving care for people with chronic conditions, including osteoarthritis (OA). Successful implementation of healthcare reform requires new concepts and directions that are strongly supported by policy, new models of care (service redesign) and changes in day-to-day practice (healthcare provider and patient practice). In this paper we discuss the extent to which policy about management of OA of the hip and knee has been translated into new service models in Australia. A structured search of government and other key health websites in Australia was performed to identify policy, funding initiatives and new services models for managing OA of the hip and knee. This search was supported by a literature review. Musculoskeletal conditions were designated a National Health Priority in Australia in 2002. Under the Better Arthritis and Osteoporosis Care initiative, Australia has developed a national policy for OA care and national evidence-based clinical practice guidelines for management of OA of the hip and knee. Only two well described examples of new chronic disease management service models, the Osteoarthritis Clinical Pathway (OACP) model and the Osteoarthritis Hip and Knee Service (OAHKS) were identified. Primarily focused within acute care public hospital settings, these have been shown to be feasible and acceptable but have limited data on clinical impact and cost-effectiveness. While policy is extant, implementation has not been systematic and comprehensive. Clinicians have evidence-based recommendations for OA management but are poorly supported by service models to deliver these effectively and efficiently.

Strong heat waves in the past decade and resulting legal cases which gave full responsibility for indoor thermal comfort to building professionals lead to an increased uncertainty how to maintain thermal comfort in offices without the use of a cooling system. Adaptive thermal comfort standards such as EN 15251 and Ashrae Standard 55 provide methodologies to evaluate comfort in naturally ventilated spaces. Based on a parametric study for a typical cellular office in the context of Athens, Greece, and using the building simulation software EnergyPlus, this study investigates the potentials for the applicability of natural ventilation in a Mediterranean climate. The Ashrae Standard 55 and EN 15251 adaptive thermal comfort models are compared in this context, and conclusions are drawn how the use of natural ventilation based on adaptive models can be further encourgaged.

Background: Schools are an ideal setting in which to involve children in research. Yet for investigators wishing to work in these settings, there are few method papers providing insights into working efficiently in this setting.

Objective: The aim of this paper is to describe the five strategies used to increase response rates, data quality and quantity in the TRansport Environment and Kids (TREK) project.

Setting: The TREK project examined the association between neighbourhood urban design and active transport in Grade 5–7 school children (n = 1480) attending 25 primary schools in metropolitan Perth, Western Australia during 2007.

Method: Children completed several survey components during school time (i.e. questionnaire, mapping activity, travel diary and anthropometric measurements) and at home (i.e. pedometer study, parent questionnaire).

Results: Overall, 69.4% of schools and 56.6% of children agreed to participate in the study and, of these, 89.9% returned a completed travel diary, 97.8% returned their pedometer and 88.8% of parents returned their questionnaire. These return rates are superior to similar studies. Five strategies appeared important: (1) building positive relationships with key school personnel; (2) child-centred approaches to survey development; (3) comprehensive classroom management techniques to standardize and optimize group sessions; (4) extensive follow-up procedures for collecting survey items; and (5) a specially designed data management/monitoring system.

Conclusion: Sharing methodological approaches for obtaining high-quality data will ensure research opportunities within schools are maximized. These methodological issues have implications for planning, budgeting and implementing future research.

Models can be excellent tools to help explain abstract scientific concepts and for students to better understand these abstract concepts. A model could be a copy or replica, but it can also be a representation that is not like the real thing but can provide insight about a scientific concept. Models come in a variety of forms, such as three dimensional and concrete, two dimensional and pictorial, and digital forms. The features of models often depend on their purpose: for example, they can be visual, to show what something might look like, dynamic to show how something might work, and or interactive to show how something might respond to changes. One model is often not an accurate representation of a concept, so multiple models may be used.
Students’ modelling ability has been shown to improve through instruction and with practice of mapping the model to the real thing, highlighting the similarities and differences. The characteristics of a model that can be used in this assessment include accuracy and purpose. Models are commonly used by science teachers to describe, and explain scientific concepts, however, pedagogical approaches that include students using models to make predictions and test ideas about scientific concepts encourages students to use models for higher order thinking processes. This approach relates the use of models to the way scientists work, reflecting the nature of science and the development of scientific ideas. This chapter will focus on the way models are used in teaching: identifying pedagogical processes to raise students’ awareness of characteristics of models. In this way, the strengths and limitations of any model are assessed in relation to the real thing so that the accuracy and merit of the model and its explanatory power can be determined.
