Coping With Social Complexity Of Infrastructure Projects, Ricardo Peculis
Coping With Social Complexity Of Infrastructure Projects, Ricardo Peculis
SMART Infrastructure Facility - Papers
Infrastructure projects are complex and technical complexity is dwarfed when compared with the social complexity caused by the interaction of individuals and organisations that participate and influence these projects. During conception and planning, uncertainty and conflicting motivations influence decisions that drive the solution and plans that are carried out during construction, operation and finally disposal of the system. If the need is not accurately conveyed and the solution is not properly defined, estimated and planned, infrastructure projects become subject of costs overrun and schedule delays of serious consequences, including the possibility that they may not satisfy the real need. Understanding …

Georeferenced social media data are gaining increased application in creating near real-time flood maps needed to improve situational awareness in data-starved regions. However, there is growing concern that the georeferenced locations of flood-related social media contents do not always correspond to the actual locations of the flooding event. But to what extent is this true? Without this knowledge, it is difficult to ascertain the accuracy of flood maps created using georeferenced social media contents. This study aims to improve understanding of the extent to which georeferenced locations of social media flood reports deviate from the actual locations of floods. The …

The last decade has witnessed the dramatic expansion of online social media at the global level. It is widely believed that the influence of social media is of particular importance for public and private organisations. Unfortunately, there is very limited and anecdotal evidence to show the durable influence of social media on various components and functions within organisations. To this end, this study examines the impact of social media, particularly taking the railway services in New South Wales (NSW), Australia and the Twitter platform as an illustrative example. Topic modelling and sentiment analysis techniques are employed to analyse collected tweets …

The principal anthropogenic factors driving reef degradation have been known for years, if not decades. Overfishing, sedimentation and nutrient loads are just some of the key impacts of human activities in and around reef communities. Therefore, the future of reefs does not rely on generating new knowledge, but rather on implementing and integrating the knowledge we already have. This will require creating effective links between researchers, managers and communities to promote mutual learning, negotiation and collaborative action for reef management. Combining agent-based models and role-play games, through a technique known as Companion Modelling (ComMod), creates a dynamic and interactive setting …
Embracing Social Uncertainties With Complex Systems Science, Pascal Perez
Embracing Social Uncertainties With Complex Systems Science, Pascal Perez
SMART Infrastructure Facility - Papers
Human ecosystems are real-life systems characterized by very strong and longterm interactions between human communities and their environment; as such they constitute an expansion of the ecological concept of ecosystem. According to Stepp and colleagues (2003), human ecosystems not only process matter and energy flows, but - and more specifically - information flows as well. Therefore, they display very specific characteristics due to our ability to communicate and learn from others, creating the conditions for co-evolutionary processes in which chance lends a hand to necessity. Bradbury (2006) argues that, until recently, human beings had been able to adapt to changes …

the classic study on diffusion of Tetracycline by Coleman, Katz and Menzel (1966). Medical Innovation articulates how different patterns of interpersonal communications can influence the diffusion process at different stages of adoption. In their pioneering study, individual network (discussion, friendship or advice) was perceived as a set of disjointed pairs, and the extent of influences were therefore, evaluated for pairs of individuals. Given the existence of overlapping networks and consequent influences on doctors’ adoption decisions, the complexity of actual events was not captured by pair analysis. Subsequent reanalyses (Burt 1987, Strang and Tuma 1993, Valente 1995, Van den Bulte and …
