Investigation into the design and development of the Toad Interactive Multimedia Program (TIMMP) and its use by first year biology undergraduates learning dissection procedures and in situ functional anatomy

Investigates how first year biology undergraduates learn dissection when they have access to such interactive multimedia technology. Related design and developmental factors were evaluated in relation to how they helped students learn the content in the multimedia program. Through the use of interactive technology students can learn at their own pace without the need for actual animal dissection.

Perfecting nature : Friedrich Nietzsche's ideal and politics of cultivation

What I have called the Ideal of Cultivation is a fundamental ethical principle of civilisation, originated by aristocratic warriors in Greek antiquity who held that the true purpose of humanity is to perfect nature

It was then professed that individuals and even entire peoples could consciously develop and improve themselves in a way that was thought to obey the original lawful impulses of nature, a process which was likened to those of agriculture and animal husbandry.

Subsequently the cognate idea of a politics of cultivation arose which deemed that society should be organised specifically to produce more virtuous or perfect human types. Given their fundamental association with Hellenism both ideas have been revisited constantly in the intellectual history of the west, and most notably during the great secular periods, the Renaissance and Enlightenment when active attempts were made to retrieve the ideals of antiquity. Both ideas were particularly pervasive in the German enlightenment, the Aufklärung, and were assimilated by the succeeding Romantic generation.

In nineteenth century Germany, when interest in these ideas was quickly waning, the German philosopher Friedrich Nietzsche acquired an unswerving attachment to them and made the service of them his life's work.

The intention of this essay is to trace methodically the appearance of the Ideal of Cultivation in Nietzsche's philosophy and politics, and to outline his responses to a world which was abandoning the principles in which he deeply believed. This essay should be regarded as a case study in the long history of a fundamental ethical idea rather than one about the philosopher Nietzsche.

Building genetic networks using relatedness information : a novel approach for the estimation of dispersal and characterization of group structure in social animals

Natal dispersal is an important life history trait driving variation in individual fitness, and therefore, a proper understanding of the factors underlying dispersal behaviour is critical to many fields including population dynamics, behavioural ecology and conservation biology. However, individual dispersal patterns remain difficult to quantify despite many years of research using direct and indirect methods. Here, we quantify dispersal in a single intensively studied population of the cooperatively breeding chestnut-crowned babbler (Pomatostomus ruficeps) using genetic networks created from the combination of pairwise relatedness data and social networking methods and compare this to dispersal estimates from re-sighting data. This novel approach not only identifies movements between social groups within our study sites but also provides an estimation of immigration rates of individuals originating outside the study site. Both genetic and re-sighting data indicated that dispersal was strongly female biased, but the magnitude of dispersal estimates was much greater using genetic data. This suggests that many previous studies relying on mark–recapture data may have significantly underestimated dispersal. An analysis of spatial genetic structure within the sampled population also supports the idea that females are more dispersive, with females having no structure beyond the bounds of their own social group, while male genetic structure expands for 750 m from their social group. Although the genetic network approach we have used is an excellent tool for visualizing the social and genetic microstructure of social animals and identifying dispersers, our results also indicate the importance of applying them in parallel with behavioural and life history data.

Functional imaging to understand biomechanics : a critical tool for the study of biology, pathology and the development of pharmacological solutions

We present four case studies of the literature discussing the effects of physical forces on biological function. While the field of biomechanics has existed for many decades, it may be considered by some a poor cousin to biochemistry and other traditional fields of medical research. In these case studies, including cardiovascular and respiratory systems, we demonstrate that, in fact, many systems historically believed to be controlled by biochemistry are dominated by biomechanics. We discuss both the previous paradigms that have advanced research in these fields and the changing paradigms that will define the progressions of these fields for decades to come. In the case of biomechanical effects of flowing blood on the endothelium, this has been well understood for decades. In the cases of platelet activation and liquid clearance from the lungs during birth, these discoveries are far more recent and perhaps not as universally accepted. While only a few specific examples are examined here, it is clear that not enough attention is paid to the possible mechanical links to biological function. The continued development of these research areas, with the inclusion of physical effects, will hopefully provide new insight into disease development, progression, diagnosis and effective therapies.

Representative actions, proof of fact and author identification in copyright law: a history and a concern

Recent judgments in Australia have called for author identification in order that copyright subsistence may be established. There is a risk that such calls will be taken too literally, to the detriment of author privacy. This article considers the legal mechanisms by which author identity has historically been shielded from disclosure, without the operation of the copyright system being impaired. It expresses the hope that those who are responsible for developing copyright law will be mindful of the concern for author privacy which has long been part of copyright discourse.

Transforming history and myth: on the mutuality and separation of shared narratives in Eastern Tibet

Questioning the distinction between ‘cold’ and ‘hot’ societies, and an implied separation between myth and history, anthropologists have increasingly urged for an understanding of both myth and history as equally valid modes of shared social consciousness. This article takes up this point of view by referring to a written history of Lhagang, a town in Eastern Tibet; a history that appears to have the transformative content and oral circulation of myth. Using Lévi-Strauss’ structural analysis of myth and Santos-Granero's concept of topograms to demonstrate the mythemes that derive from the written history and circulate among Lhagang Tibetans, the article argues that, within the political and cultural context of Lhagang, myth and history shift in and out of indigenous categories even while being categorically distinct.
