Addressing cultural, social and environmental sustainability in architecture. The approach of five contemporary Australian architects

Regionalist architecture offers a promising and conscientious response to the present scenario of growing trend toward cultural, social and technical globalization. It has a great potential to preserve local cultural identities, despite the spread of global culture, to define possible relationships between construction and natural, cultural, political, economic and social factors, to combine traditional approaches and technical skills creatively and to suggest a new role for designers, as active subjects in dialogue with the manufacturing sector. An exemplary regionalist approach to contemporary architecture is given by a niche of Australian architects sensitive to the relation between communities and technical skills, dwelling patterns and building techniques, who tend to reduce the environmental load of construction through the use of local resources, who adopt community design processes and combine tradition with creative innovation. Glenn Murcutt, Richard Leplastrier, Peter Stutchbury, Gregory Burgess and Troppo Architects, who, learning from Aboriginal people's sacred respect for the land, balance the tension between global needs and local expressions, by listening to people and place, preserving traditional lifestyle preferences and combining new technologies with historic building types

A global-scale analysis of the sharing economy model – an AirBnB case study

Abstract: The sharing economy model has changed the way in which people engage in a variety of activities, including travelling, trading, working, and lending/borrowing money. Several studies exist that aim to understand, quantify and model such phenomenon, but most such studies are geographically focused on countries in the Western World. Knowledge about the penetration and adoption of this novel market model in non-Western countries is much more limited, and almost completely lacking when it comes to emerging markets, where it was touted to bring the biggest benefits and be a game changer to uplift people economically. To close the gap, we chose Airbnb as an example of sharing economy model with worldwide market penetration, and performed a large-scale quantitative study of its penetration and adoption in seven cities in Asia, five cities in Latin America. We compared findings against seven cities in the Western World, and observed patterns to be similar across all locales, with two notable exceptions: the geographic penetration of such services, and the experience that guests travelling to such destinations shared in their reviews

Social contribution settings and newcomer retention in humanitarian crowd mapping

Organisers of crowd mapping initiatives seek to identify practices that foster an active contributor community. Theory suggests that social contribution settings can provide important support functions for newcomers, yet to date there are no empirical studies of such an effect. We present the first study that evaluates the relationship between colocated practice and newcomer retention in a crowd mapping community, involving hundreds of first-time participants. We find that certain settings are associated with a significant increase in newcomer retention, as are regular meetings, and a greater mix of experiences among attendees. Factors relating to the setting such as food breaks and technical disruptions have comparatively little impact. We posit that successful social contribution settings serve as an attractor: they provide opportunities to meet enthusiastic contributors, and can capture prospective contributors who have a latent interest in the practice

Exploring maintenance practices in crowd-mapping

Crowd-mapping is a form of collaborative work that empowers users to gather and share geographic knowledge. OpenStreetMap is one of the most successful examples of such paradigm, where the goal of building a global map of the world is collectively performed by over 2M contributors. Despite geographic information being intrinsically evolving, little research has so far gone into analysing maintenance practices in these domains. In this paper, we perform a preliminary exploration to quantitatively capture maintenance dynamics in geographic crowd-sourced datasets, in terms of: the extent to which different maintenance actions are taking place, the type of spatial information that is being maintained, and who engages in these practices. We apply this method to 117 countries in OSM, over one year of mapping activity. Our findings reveal that, although maintenance practices vary substantially from country to country in terms of how widespread they are, strong commonalities exist in terms of what metadata is being maintained and by whom

City form and well-being: what makes London neighborhoods good places to live?

What is the relationship between urban form and citizens’ well-being? In this paper, we propose a quantitative approach to help answer this question, inspired by theories developed within the fields of architecture and population health. The method extracts a rich set of metrics of urban form and well-being from openly accessible datasets. Using linear regression analysis, we identify a model which can explain 30% of the variance of well-being when applied to Greater London, UK. Outcomes of this research can inform the discussion on how to design cities which foster the wellbeing of their residents
