Digital ubiquity in the Anthropocene : the non-anthropocentric anthropology of Massimo Canevacci

The work of Massimo Canevacci is undoubtedly one of the most compelling examples of transdisciplinary thinking when applied to the interdisciplinary effort of expanding the boundaries of a discipline. His work engages with geography, art, technology, media, psychology, etc – a true kaleidoscope of perspectives. The synapses created by the transversal connections he makes across a multiplicity of epistemologies are catalytic. To follow the logical itinerary created by his scholarly inquiry is to be taken on a journey that leaves none of our pre-conceptions untouched.

Ageing in an ultra-dense metropolis: perceived neighbourhood characteristics and utilitarian walking in Hong Kong elders

Objective
The neighbourhood built environment may affect walking behaviour of elders. However, such effects remain underexplored, especially in an Asian context. We examined associations of perceived environmental attributes with overall and neighbourhood-specific walking for transport in a sample of Chinese elders residing in Hong Kong, an ultra-dense Chinese metropolis.

Design
Cross-sectional observational study using a two-stage stratified sampling strategy.

Setting
Hong Kong, China.

Subjects
Chinese-speaking elders (n 484), with no cognitive impairment and able to walk without assistance, residing in thirty-two selected communities stratified by socio-economic status and walkability, were interviewer-administered validated measures of perceived neighbourhood environment and walking for transport.

Results
Much higher levels of transport-related walking (mean 569 (sd 452) min/week) than found in Western samples were reported. The degree of perceived access to shops, crowdedness, presence of sitting facilities and easy access of residential entrance were independently positively related to both frequency of overall and within-neighbourhood walking for transportation. Infrastructure for walking and access to public transport were predictive of higher frequency of transport-related walking irrespective of location, while the perceived degree of land-use mix was predictive of higher levels of within-neighbourhood walking.

Conclusions
The provision of easy access to shops, residential entrances and sitting facilities in the neighbourhood may promote overall transport-related walking, while a good public transport network and pedestrian infrastructure linking destination-poor with destination-rich locations may compensate for the detrimental effects of living in less walkable neighbourhoods. Governmental investment in these micro- and macro-environmental features would help the promotion of an active lifestyle in elders.

Comparison of Two Methods for Caluculating the Partition Functions of Various Spatial Statistical Models

Likelihood computation in spatial statistics requires accurate and efficient calculation of the normalizing constant (i.e. partition function) of the Gibbs distribution of the model. Two available methods to calculate the normalizing constant by Markov chain Monte Carlo methods are compared by simulation experiments for an Ising model, a Gaussian Markov field model and a pairwise interaction point field model.

Encountering place : tripping to the point

The Nepean Peninsula, a tiny sliver of land at the end of the Mornington Peninsula, Victoria, Australia, has lured humans over eons. Together with the Bellarine Peninsula it forms the gateway to Port Philip Bay at the Heads. It shields the Bay from the tumultuous forces of Bass Strait. Here  generations have been drawn to the seaside, to an inspirational coastal landscape. Today hurtling at 100 km per hour down the Mornington Peninsula Freeway one reaches decision point in less than an hour: the coast road or the inland road? Next looms the junction of the Old Melbourne Road and the Nepean Highway. Another decision: which road will be quicker? Where will the traffic snarl be this time? One is oblivious to the remnant moonah woodland which once covered the land; unaware of the seascape to either side; no longer in tune with the rhythm of the tides. And yet people today still feel that sense of relief and freedom of escape from the metropolis with their first 'sniff of the briny'. Through contemporary accounts and visual material this paper explores the roads that have been travelled to get to the Nepean Peninsula: by land and sea.

Hanoi, Vietnam : representing power in and of the nation

Hanoi, like most capital cities, performs functions at three levels. It is home to its residents and provides local level services for them. But it also has a role as a city for all citizens of the Vietnamese state, performing capital city functions across the entire national territory as well as beyond national borders. Hanoi is especially interesting because of the uneasy way in which it has been forced to share power internally with Ho Chi Minh City in the south—Hanoi maintaining political and cultural sway but its rival becoming stronger in economic and demographic terms. Externally, it has struggled for recognition, having been regarded as capital of a weak political state open to the interventions of the Chinese, French, Americans and the Soviet Union. This paper argues that Hanoi's double vulnerability has made its rulers acutely aware of the need to demonstrate the city's power as a capital city—or at least to give the semblance of power—through urban planning and architectural design, the building of heroic monuments and the naming of city features after key historic events and people. Major events and projects have become an important way in which the Vietnamese government has sought to strengthen Hanoi's place—and hence its own—in the national consciousness. The regime also continues to push on with efforts to make a future Hanoi dominant both within the Vietnamese urban hierarchy and as the country's undisputed international metropolis.

Developing sustainable communities : the case for Port Phillip Heads historic towns, Sorrento and Queenscliff

The Victorian towns of Sorrento and Queenscliff are located either side of Port Phillip Heads. Using these towns as case studies, this paper examines what happens to historic coastal townships caught up in the phenomenon of sea change. Both towns are currently facing huge planning battles and are trying to argue a case for heritage in the rush for expansion and modernisation. Newcomers like to emulate the metropolis in the seaside towns. Planners in the metropolis are asked to make decisions by developers who are thwarted by local municipalities. These towns encapsulate something of the dilemma that comes with a demographic shift from the metropolitan centre to coastal townships and demonstrate that the transition from urban life and built environment does not translate without cost to a fragile coastal environment. It is place itself that has attracted humans to Sorrento and Queenscliff over centuries. The seascape, the landscape, the environment drew the indigenous peoples here centuries ago. It provided abundant food and was inspiring. Europeans came at the very beginning of the 19th century seeking new lands. By the late decades of the 19th century Europeans discovered the seaside and its health giving qualities and built substantial Victorian edifices to house the influx of visitors and holiday-makers who arrived by ferry. However, not until the second half of the twentieth century did development begin to intrude significantly on the landscape. And by the twenty-first century evidence is mounting that development is destroying the sense and character of place, which initially enticed people to come here.

Towering over all : the Italianate villa in the colonial landscape

The Picturesque aesthetic emerged in the later 18th century, uniting the Sublime and the Beautiful and had its roots in the paintings of Claude Lorrain. In Britain, and in Australia, it came to link art, literature and landscape with architecture. The Picturesque aesthetic informed much of colonial culture which was achieved, in part, through the production and dissemination of architectural pattern books catering for the aspirations of the rising middle classes. This was against a background of political change including democratic reform. The Italianate villa, codified and promoted in such pattern books, was a particularly successful synthesis of style, form and function. The first Italianate villa in England, Cronkhill (1803) by John Nash contains all the ingredients which were essential to the model and had a deeper meaning. Deepdene (from 1807) by Thomas Hope gave the model further impetus. The works of Charles Barry and others in a second generation confirmed the model's acceptability. In Britain, its public status peaked with Osborne House (from 1845), Queen Victoria's Italianate villa on the Isle of Wight, Robert Kerr used a vignette of Osborne House on the title page of his sophisticated and influential pattern book, The Gentleman's House (1864,1871). It was one of many books, including those of J.C, Loudon and AJ. Downing, current in colonial Victoria. The latter authors and horticulturists were themselves villa dwellers with libraries and orchards, two criteria for the true villa lifestyle. Situation and a sense of retreat were the two further criteria for the villa lifestyle. As the new colony of Victoria blossomed between 1851 and 1891, the Italianate villa, its garden setting and its landscape siting captured the tenor of the times. Melbourne, the capital was a rich manufacturing metropolis with a productive hinterland and international markets. The people enjoyed a prosperity and lifestyle which they wished to display. Those who had a position in society were keen to demonstrate and protect it. Those with aspirations attempted to provide the evidence necessary for such acceptance, The model matured and became ubiquitous. Its evolution can be traced through a series of increasingly complicated rural and suburban examples, a process which modernist historians have dismissed as a decadent decline. These villas, in fact, demonstrate an increasingly sophisticated retreat by merchants from ‘the Town’ and by graziers from ‘the Country’. In both town and country, the towers of villas mark territory newly acquired. The same claim was often made in humbler situations. Government House, Melbourne (from 1871), a splendid Italianate villa and arguably finer than Osborne House, was set in a cultivated landscape and towered above all It incorporated the four criteria and, in addition, claimed its domain, focused authority and established the colony's social status. It symbolised ancient notions of democracy and idealism but with a modem appreciation for the informal and domestic. Government House in Melbourne is the epitome of the Italianate villa in the colonial landscape and is the climax of the Picturesque aesthetic in Victoria.

The hidden permutation model and location-based activity recognition

Permutation modeling is challenging because of the combinatorial nature of the problem. However, such modeling is often required in many real-world applications, including activity recognition where subactivities are often permuted and partially ordered. This paper introduces a novel Hidden Permutation Model (HPM) that can learn the partial ordering constraints in permuted state sequences. The HPM is parameterized as an exponential family distribution and is flexible so that it can encode constraints via different feature functions. A chain-flipping Metropolis-Hastings Markov chain Monte Carlo (MCMC) is employed for inference to overcome the O(n!) complexity. Gradient-based maximum likelihood parameter learning is presented for two cases when the permutation is known and when it is hidden. The HPM is evaluated using both simulated and real data from a location-based activity recognition domain. Experimental results indicate that the HPM performs far better than other baseline models, including the naive Bayes classifier, the HMM classifier, and Kirshner's multinomial permutation model. Our presented HPM is generic and can potentially be utilized in any problem where the modeling of permuted states from noisy data is needed.

Walking for recreation and perceptions of the neighbourhood environment in older chinese urban dwellers

Engagement in walking for recreation can contribute to healthy aging. Although there is growing evidence that the neighborhood environment can influence walking for recreation, the amount of such evidence in relation to older adults is scarce and limited to Western low-density urban locations. Asian urban environments are typified by distinctive environmental and cultural characteristics that may yield different patterns to those observed in Western countries. Therefore, the main aim of this study was to examine associations of perceived environmental attributes with overall and within-neighborhood walking for recreation in Chinese elders (65+ years) residing in Hong Kong, an ultradense Asian metropolis. A sample of 484 elders was recruited from 32 neighborhoods stratified by socio-economic status and walkability (dwelling and intersection densities). Validated questionnaires measuring perceived neighborhood environment and weekly minutes of overall and within-neighborhood walking for recreation were interviewer administered. Results showed that the level of recreational walking was twice to four times higher than that reported in Western adults and elders. While overall walking for recreation showed a general lack of associations with perceived environmental attributes, within-neighborhood recreational walking was positively related with proximity of recreational facilities, infrastructure for walking, indoor places for walking, and presence of bridge/overpasses connecting to services. Age and educational attainment moderated the associations with several perceived environmental attributes with older and less-educated participants showing stronger associations. Traditional cultural views on the benefits of physical activity and the high accessibility of facilities and pedestrian infrastructure of Hong Kong may explain the high levels of walking. Although specific neighborhood attributes, or their perception, may influence recreational walking within the neighborhood, the compactness and public transport affordability of ultradense metropolises such as Hong Kong may make it easy for elders to compensate for the lack of favorable neighborhood attributes by walking outside the neighborhood.

Learning from ordered sets and applications in collaborative ranking

Ranking over sets arise when users choose between groups of items. For example, a group may be of those movies deemed 5 stars to them, or a customized tour package. It turns out, to model this data type properly, we need to investigate the general combinatorics problem of partitioning a set and ordering the subsets. Here we construct a probabilistic log-linear model over a set of ordered subsets. Inference in this combinatorial space is highly challenging: The space size approaches (N!/2)6.93145N+1 as N approaches infinity. We propose a split-and-merge Metropolis-Hastings procedure that can explore the state-space efficiently. For discovering hidden aspects in the data, we enrich the model with latent binary variables so that the posteriors can be efficiently evaluated. Finally, we evaluate the proposed model on large-scale collaborative filtering tasks and demonstrate that it is competitive against state-of-the-art methods.

Understanding the tensions in place – conflict and conservation in Kashmir

The ongoing evolution of the global heritage movement has been marked by a move away from fabric-centred understandings of heritage, towards a language of ‘place’, ‘values’ and ‘stakeholders’. Recent initiatives like the ‘Vienna Memorandum on Historic Urban Landscapes’ and the ‘Seoul Declaration on Heritage and the Metropolis in Asia and the Pacific’ represent important steps in such directions for managing the heritage of urban environments. This paper examines these developments in the context of Srinagar, the capital city of Indian administered Kashmir. With the conflict in the region enduring for more than fifteen years, the city - regarded as one of the most important pre-modern urban landscapes in South Asia - has suffered extensive physical damage. Nonetheless, the city remains the cultural and political heart of a wider collective identity rooted in the Kashmir Valley. As such, Srinagar presents a rich example of a city that would strongly benefit from the insights gained from Seoul and Vienna; an approach that recognises how a sense of ‘place’ arises through an intimate dialogue between the built environment and the socio-cultural context within which it sits. However, as we shall see, a framework oriented around ‘values’ and ‘context’ opens up unfamiliar and difficult questions and challenges. If a city like Srinagar is to be discussed in more holistic, less fabric-based terms, the interfaces between heritage and its wider social values, such as cultural sovereignty, multi-culturalism or democracy require far greater attention than they have received to date.

Paranormal politics and the romance of urban subcultures: youth mobility in Cassandra Clare’s and Melissa Marr’s fantasy texts

This essay examines the political and social significance of the intrusion of the supernatural into youth subcultures in two urban fantasy series: Cassandra Clare’s Mortal Instruments and Melissa Marr’s Wicked Lovely. Both series represent the idea of human youth mobility and social affiliation based on volition. The tolerant urban spaces through which their girl protagonists initially move accommodate a diversity of subcultural aesthetics. By contrast, the supernatural subcultures with which these girls become involved are fraught with conflict, and the mobility of their members is limited. Drawing on post-subcultural theory, we identify a tension between late modern and premodern social organization and political values in contemporary urban fantasy for young adults and compare how it is resolved in Clare’s and Marr’s texts.
