Is narrative identity four-dimensionalist?

The claim that selves are narratively constituted has attained considerable currency in both analytic and continental philosophy. However, a set of increasingly standard objections to narrative identity are also emerging. In this paper, I focus on metaphysically realist versions of narrative identity theory, showing how they both build on and differ from their neo-Lockean counterparts. But I also argue that narrative realism is implicitly committed to a four-dimensionalist, temporal-parts ontology of persons. That exposes narrative realism to the charge that the narratively constituted self, on the one hand, and the self that is the object of much of our everyday self-reference and self-experience, on the other, can’t be the same thing. This conclusion may well force narrativists to abandon metaphysical realism about narrative selves — which, in turn, may leave the invocation of ‘narrativity’ as identity-constituting somewhat under-motivated.

Unpacking black boxes: Mechanisms and theory building in evaluation

There is growing interest in the concept of ‘‘mechanism’’ across many areas of the social sciences. In the field of program and policy evaluation, a number of scholars have also emphasized the importance of causal mechanisms for explaining how and why programs work. However, there appears to be some ambiguity about the meaning and uses of mechanism-based thinking in both the social science and evaluation literature. In this article we attempt to clarify what is meant by mechanisms in the context of program evaluation by identifying three main characteristics of mechanisms and outlining a possible typology of mechanisms. A number of theoretical and practical implications for evaluators are also discussed, along with some precautions to consider when investigating mechanisms that might plausibly account for program outcomes.

Theory and Australian foreign policy

An analysis of the theoretical basis of Australian foreign policy, comparing realism and the English School

US policy toward rogue states: Comparing the Bush administration's policy toward Iraq and North Korea

The George W. Bush administration resorted to war to respond to the threat of weapons of mass destruction in Iraq, whereas it virtually ruled out the use of force to resolve the North Korean nuclear issue. By utilizing various strands of realist international relations theories, we trace motivations behind the administration's divergent foreign-policy choices toward rogue states. That the United States rushed to war against Iraq while procrastinating on North Korea presents a puzzle to conventional realism, which postulates that great powers observe changes in relative capabilities and respond accordingly. We argue that policy differences should be embedded in discussion of the administration's foreign-policy grand strategy, which sought to sustain the hegemonic status of the United States in the world. Iraq and North Korea had different implications for Bush's grand strategy, thereby calling for different approaches. By tracing the strategic design of the Bush administration, we attempt to provide a more complete account of policy differences toward rogue states, as well as indicate the significant changes in US policy during the George W. Bush administration and since.

Grounded theory and leadership research: a critical realist perspective

The methodology of grounded theory has great potential to contribute to our understanding of leadership within particular substantive contexts. However, our notions of good science might constrain these contributions. We argue that for grounded theorists a tension might exist between a desire to create a contextualised theory of leadership and a desire for scientifically justified issues of validity and generalizable theory. We also explore how the outcome of grounded theory research can create a dissonance between theories that resonate with the reality they are designed to explore, and the theories that resonate with a particular yet dominant 'scientific' approach in the field of leadership studies - the philosophy of science commonly known as positivism. We examine the opportunities provided by an alternative philosophy of science, that of critical realism. We explore how conducting grounded theory research informed by critical realism might strengthen researchers' confidence to place emphasis on an understanding and explanation of contextualised leadership as a scientific goal, rather than the scientific goal of generalization through empirical replication. Two published accounts of grounded theory are critiqued candidly to help emphasise our arguments. We conclude by suggesting how critical realism can help shape and enhance grounded theory research into the phenomenon of leadership. © 2010.

Viewing the leadership narrative through alternate lenses: an autoethnographic investigation

This conceptual-theoretical article revisits the work of Parry and Hansen on the nature of the organizational story as leadership. The present article is written in the autoethnographic style. The original narrative work is re-examined through the lenses of autoethnography, narrative theory, metaphor/discourse, critical realism and conventional quantitative research. The insights provided by this methodological triangulation are examined. The conclusion is that organizational stories will reflect leadership if they are plausible to the intended audience, give all organizational members an empowered part in the story, have a moral to the story, and have a happy ending. The overarching theme that is proposed is of leadership as the generation of individual hope for a better existence.

Barriers and enablers to learning during team-based clinical simulations: reflective interviews with final year undergraduate nursing students

Background: Contemporary approaches to clinical simulation can enhance educational outcomes. However, simulation approaches do have limitations with possible compromises for learning and teaching. This paper aims to identify barriers
and enablers to learning in simulated clinical settings.
Methods: A generic qualitative design was applied. Semi-structured group video debriefing interviews were held with Australian final-year nursing students who completed three patient deterioration scenarios with a standardized patient.
Audio-recorded interviews were transcribed and analysed to identify emergent themes.
Results: Interviews with 15 teams of three students (n = 45) from three universities were analysed. Learning enablers were ‘Realism of the simulated environment’; ‘Practicing: we should do this at uni’; ‘Learning from reflection and expert feedback’, and ‘How to become competent: know the gaps’. Barriers to learning included ‘Increased stress from inexperience; ‘Expectations when pretending’ and ‘Lack of assistance’. Skills practice in team-based settings with applicable reflection and debriefing was regarded as beneficial. Simulated patients enhanced fidelity but were unable to replicate actual clinical signs. High stress levels were perceived as a barrier to learning.
Conclusions: Applicably designed high fidelity simulations with video-based reflective review offer repeated rehearsal of clinical situations to enable learning. This educational strategy may reduce the time it takes undergraduate students to
reach competency.

The IUCN red list of ecosystems: motivations, challenges, and applications

In response to growing demand for ecosystem-level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard for ecosystem risk assessment. Four qualities were sought in the design of the IUCN criteria: generality; precision; realism; and simplicity. Drawing from extensive global consultation, we explore trade-offs among these qualities when dealing with key challenges, including ecosystem classification, measuring ecosystem dynamics, degradation and collapse, and setting decision thresholds to delimit ordinal categories of threat. Experience from countries with national lists of threatened ecosystems demonstrates well-balanced trade-offs in current and potential applications of Red Lists of Ecosystems in legislation, policy, environmental management and education. The IUCN Red List of Ecosystems should be judged by whether it achieves conservation ends and improves natural resource management, whether its limitations are outweighed by its benefits, and whether it performs better than alternative methods. Future development of the Red List of Ecosystems will benefit from the history of the Red List of Threatened Species which was trialed and adjusted iteratively over 50 years from rudimentary beginnings. We anticipate the Red List of Ecosystems will promote policy focus on conservation outcomes in situ across whole landscapes and seascapes.

Landscaping on shifting ground: teacher education in a digitally transforming world

For almost three decades, the landscape of teacher education has been modestly shaped by the exploration of practices that made use of what were, at the time, current instances of computing and communication technologies (CCTs). More broadly and importantly however, the deployment of CCTs globally has, over the same time period (1980-2008), supported a reshaping of the planet's social, economic and political circumstances in which all forms of education operate. Despite the enormity of these shifts the focus in teacher education has remained largely at site, reflecting a similar focus in schools. In fact, the patterns of adaption and response in teacher education to each new instance of high-tech product are now quite predictable. Thus, while teacher education's engagement with CCTs can be mapped as a kind of minor landscaping, a process which attends more to appearance than substance, it is landscaping effectively premised upon a stable geography, one that resembles that of thirty years ago. This paper explores the changed and changing geography of a world heavily shaped by the ongoing deployment and use of more and more powerful CCTs. The analysis suggests that if we continue to attend only to landscaping, teacher education will be at risk of being terraformed.

Novel design of a renewable energy remote laboratory

BACKGROUND OR CONTEXT: Current work in remote laboratories focuses on student interaction in a setting that can be at times disconnected from real world systems. Laboratories have been developed that show models of a working system, focusing on a single aspect, but very few laboratories allow the user to see the outputs of a working system that interacts with the real world as would be expected outside of a laboratory setting. It was aimed with this paper to show a design of a novel approach to building a remote laboratory that would be able to interact with a fully functional renewable energy system, and to show the students the outputs of such a system in real time. It allows for the user to be presented with information in a new context.
PURPOSE OR GOAL: With this research it is hoped to achieve a remote laboratory that will be able to present students with the data from a renewable energy system live, as it is generated as well as all the logged date generated. It is aimed with this novel approach to building a remote laboratory to assist the students in learning about renewable energy systems while allowing the student to access real data, instead of simulated data. Links to increased motivation due to realism in data given as well as change in student perception on learning in remote laboratories mean that a system such as this could change the way students approach learning about renewable energy generation systems. This will require further research however.
APPROACH: This remote laboratory required gathering data from an already established system. The live results were not recorded, and a log file was generated daily, however this was not fast enough to give to students as it was generated, so a system that could maintain communication between all systems, while also polling for data itself was required. In addition to this, the system had to communicate to a server that would give students access to the live data. The server was set up in such a way that students were not required to install any programs on their computer, multiple students could access the data at any given time, and a wide range of devices, including mobile devices, could all access the remote laboratory.
DISCUSSION: Key outcomes include the design of the remote laboratory, including screenshots of data acquisition from the renewable energy system from different devices. The design is split into two sections, one covering the server side architecture while another covers the data acquisition architecture. A very brief discussion on students’ initial interaction is also undertaken.
RECOMMENDATIONS/IMPLICATIONS/CONCLUSION: Research has shown that the degree of realism in remote education can have an effect on students’ behaviors/motivation in a remote laboratory. By allowing students to knowingly access a real system that is currently being used to generate power from renewable energy sources, the methods and motivations that students use when approaching renewable energy systems may change.

Automatic generation of traditional style painting by using density-based color clustering

In this paper, a novel approach is proposed to automatically generate both watercolor painting and pencil sketch drawing, or binary image of contour, from realism-style photo by using DBSCAN color clustering based on HSV color space. While the color clusters produced by proposed methods help to create watercolor painting, the noise pixels are useful to generate the pencil sketch drawing. Moreover, noise pixels are reassigned to color clusters by a novel algorithm to refine the contour in the watercolor painting. The main goal of this paper is to inspire non-professional artists' imagination to produce traditional style painting easily by only adjusting a few parameters. Also, another contribution of this paper is to propose an easy method to produce the binary image of contour, which is a vice product when mining image data by DBSCAN clustering. Thus the binary image is useful in resource limited system to reduce data but keep enough information of images. © 2007 IEEE.

Does a combination of virtual reality, neuromodulation and neuroimaging provide a comprehensive platform for neurorehabilitation? - A narrative review of the literature

In the last decade, virtual reality (VR) training has been used extensively in video games and military training to provide a sense of realism and environmental interaction to its users. More recently, VR training has been explored as a possible adjunct therapy for people with motor and mental health dysfunctions. The concept underlying VR therapy as a treatment for motor and cognitive dysfunction is to improve neuroplasticity of the brain by engaging users in multisensory training. In this review, we discuss the theoretical framework underlying the use of VR as a therapeutic intervention for neurorehabilitation and provide evidence for its use in treating motor and mental disorders such as cerebral palsy, Parkinson’s disease, stroke, schizophrenia, anxiety disorders, and other related clinical areas. While this review provides some insights into the efficacy of VR in clinical rehabilitation and its complimentary use with neuroimaging (e.g., fNIRS and EEG) and neuromodulation (e.g., tDCS and rTMS), more research is needed to understand how different clinical conditions are affected by VR therapies (e.g., stimulus presentation, interactivity, control and types of VR). Future studies should consider large, longitudinal randomized controlled trials to determine the true potential of VR therapies in various clinical populations.

Biologically inspired vector fields to generate hair directions

This paper describes how biologically inspired vector fields can be used to partially automate the manual and time-consuming process of specifying hair directions. This approach replicates the consequence of stretching of skin from natural hair development process, in contrast to replicating the appearance of hair. The direction of each hair on the surface of an arbitrary 3D model is determined by interpolating the solution vector field that satisfies a set of user-defined constraints describing the stretching of skin. Results found that the generated hair directional pattern closely resembles that found naturally. Further investigation revealed that the presence of naturally occurring hair types and the varying distribution of hair directions induced by the calculated vector field enhanced the realism of hair coats generated using this approach. Aside from hair or fur, this approach can also be applied to hair-like masses such as grass, feathers, or scales.

Re-processing The Mystical Rose

This essay explores the animation practice of Australian filmmaker Michael Lee, whose career spans the late 60s to the present. His notoriously dissident and innovative feature length work The Mystical Rose (1976, 65 minutes) is the primary focus, the fulcrum point of an analysis balanced by a review of his earlier shorter formative films, his cultural milieu, the thinkers that shaped his youth and particularly his changing relation to the Catholic Church. This relationship with Christianity has gone full circle through a critical rejection, worked through in The Mystical Rose, to a re-embrace in his later films Turnaround (1983, 60 mins) and The Contemplation of the Cross (1989, 27 minutes). This trajectory is understood here in relation to Magic Realism, Michael Bakhtin’s conception of the ‘Carnivalesque’ and Surrealism. What is of particular interest historically for animation is Lee’s pioneering innovative combination of animation with live action documentation, conveying both inner and outer realities, and mapping the relationships between them.
