RED COATS AND WILD BIRDS: MILITARY CULTURE AND ORNITHOLOGY ACROSS THE NINETEENTH-CENTURY BRITISH EMPIRE

“Red coats and wild birds: military culture and ornithology across the nineteenth-century British Empire” investigates the intersections between British military culture and the practices and ideas of ornithology, with a particular focus on the British Mediterranean. Considering that British officers often occupied several imperial sites over the course of their military careers, to what extent did their movements shape their ornithological knowledge and identities at “home” and abroad? How did British military naturalists perceive different local cultures (with different attitudes to hunting, birds, field science, etc.) and different local natures (different sets of birds and environments)? How can trans-imperial careers be written using not only textual sources (for example, biographies and personal correspondence) but also traces of material culture? In answering these questions, I centre my work on the Mediterranean region as a “colonial sea” in the production of hybrid identities and cultural practices, and the mingling of people, ideas, commodities, and migratory birds. I focus on the life geographies of four military officers: Thomas Wright Blakiston, Andrew Leith Adams, L. Howard Lloyd Irby, and Philip Savile Grey Reid. By the mid-nineteenth century, the Mediterranean region emerged as a crucial site for the security of the British “empire route” to India and South Asia, especially with the opening of the Suez Canal in 1869. Military stations served as trans-imperial sites, connecting Britain to India through the flow of military manpower, commodities, information, and bodily experiences across the empire. By using a “critical historical geopolitics of empire” to examine the material remnants of the “avian imperial archive,” I demonstrate how the practices and performances of British military field ornithology helped to: materialize the British Mediterranean as a moral “semi-tropical” place for the physical and cultural acclimatization of British officers en route to and from India; reinforce imperial presence in the region; and make “visible in new ways” the connectivity of North Africa to Europe through the geographical distribution of birds. I also highlight the ways in which the production of ornithological knowledge by army officers was entwined with forms of temperate martial masculinity.

AUSTRALIA’S STRATEGIC CULTURE: An investigation of the concept of strategic culture and its application to the Australian case

The notion that each state in the international system approaches matters of war and peace somewhat differently because they each possess a unique strategic culture is not a new or obscure one – but it nevertheless remains controversial. While some scholars dismiss the utility or practicality of examining states’ cultures when seeking to explain or predict those states’ patterns of strategic decision-making, even amongst those who accept that we should pay attention to cultural differences between states when carrying out strategic analysis there remains a frustratingly eclectic range of offerings from scholars regarding how best to do so. In short, significant uncertainty remains regarding both whether strategic culture should be used as an analytical tool and, if it is so utilized, how one should go about doing so. This thesis therefore explores the concept of strategic culture in great detail, both theoretical and empirical. The opening three chapters examine why the more traditional rationalist/materialistic theories should not exclusively dominate strategic analysis, then the various existing strategic cultural offerings are considered and critiqued and, finally, a new conceptual model for strategic cultural analysis is proposed which draws from the hitherto largely neglected psychological and sociological literature. Both of these fields, it is submitted in Chapter 3, have spent more time and effort developing ways of understanding and analyzing culture than the field of IR has to date, and therefore the models and methods debated and developed in these fields should, it is argued, be ‘imported’ into IR to drive further strategic cultural research. The thesis then moves in the following six chapters to consider Australia’s strategic culture. The purpose of this part of the thesis is two-fold: first, it illustrates how the model offered in Chapter 3 works and, by implication, suggests how scholars may go about applying it to other cases. Second, and perhaps more importantly, the latter six chapters explore the twists and turns of Australia’s substantive strategic decision-making over the course of the last century or more, thereby explaining how Australia’s strategic history can be understood from a cultural perspective.

Functional characterization of a Kar3/Vik1-like Kinesin-14 heterodimer from the filamentous multinucleate fungus Ashbya gossypii

Kinesins are motor proteins that convert chemical energy from ATP hydrolysis into mechanical energy used to generate force along microtubules, transporting organelles, vesicles, and proteins within the cell. Kar3 kinesins are microtubule minus-end-directed motors with pleiotropic functions in mating and mitosis of budding and fission yeast. In Saccharomyces cerevisiae, Kar3 is multifunctionalized by two non-catalytic companion proteins, Vik1 and Cik1. A Kar3-like kinesin and a single Vik1/Cik1 ortholog are also expressed by the filamentous fungus Ashbya gossypii, which exhibits different nuclear movement challenges and unique microtubule dynamics from its yeast relatives. We hypothesized that these differences in A. gossypii physiology could translate into interesting and novel differences in its versions of Kar3 and Vik1/Cik1. Presented here is a structural and functional analysis of recombinantly expressed and purified forms of these motor proteins. Compared to the previously published S. cerevisiae Kar3 motor domain structure (ScKar3MD), AgKar3MD displays differences in the conformation of the ATPase pocket. Perhaps it is not surprising then that we observed the maximal microtubule-stimulated ATPase rate (kcat) of AgKar3MD to be approximately 3-fold slower than ScKar3MD, and that the affinity of AgKar3MD for microtubules (Kd,MT) was lower than ScKar3MD. This may suggest that elements that compose the ATPase pocket and that participate in conformational changes required for efficient ATP hydrolysis or products release work differently for AgKar3 and ScKar3. There are also subtle structural differences in the disposition of the secondary structural elements in the small lobe (B1a, B1b, and B1c) at the edge of the motor domain of AgKar3 that may reflect the enhanced microtubule-depolymerization activity that we observed for this motor, or they could relate to its interactions with a different regulatory companion protein than its budding yeast counterpart. Although we were unable to gain experimentally determined high-resolution information of AgVik1, the results of Phyre2-based bioinformatics analyses may provide a structural explanation for the limited microtubule-binding activity we observed. These and other fundamental differences in AgKar3/Vik1 could explain divergent functionalities from the ScKar3/Vik1 and ScKar3/Cik1 motor assemblies.
