Public Discourse and Category Formation: A Topic Modelling Exploration of ‘Historical Shops’ on Italian Media

This paper addresses the role of public discourse in processes of category formation. Tracing the emergence and diffusion of a category on the media, and exploring the discourses generated on the media within and around the emerging category, the paper reflects on how these discourses concur in performing the very category they portray. The focus is set on the Historical Shops category, as part of broader processes of urban categorisations for local development and regeneration. By means of a Topic Modelling of a corpus of 3262 press articles collected from Italian news sources between 2009 and 2019, the paper finds that public discourse plays three main roles: echoing category creation processes by policymakers, grounding the rising category in wider discourses of retail crisis, urban degradation, regeneration and overtourism, and narrating it by explaining what Historical Shops are, where they are located, which issues they face and which responses they receive at different institutional levels. Overall, in this paper, the semi-automated techniques afforded by Topic Modelling offer a way to enter the meaning construction processes and elicit the agential role of public discourse in the formation of a category

Questions of agency: capacity, subjectivity, spatiality and temporality

Geographies of Children, Youth and Families is flourishing, but its founding conceptions require critical reflection. This paper considers one key conceptual orthodoxy: the notion that children are competent social actors. In a field founded upon liberal notions of agency, we identify a conceptual elision between the benefits of studying agency and the beneficial nature of agency. Embracing post-structuralist feminist challenges, we propose a politically-progressive conceptual framework centred on embodied human agency which emerges within power. We contend this can be achieved though intensive/extensive analyses of space, and a focus on biosocial beings and becomings within dynamic notions of individual/intergenerational time

Bringing History into Evolutionary Economic Geography for a Better Understanding of Evolution

The paper tries to construct the historical methodology for evolutionary economic geography. I elevate history to the methodological foundation of evolutionary economic geography, on which concrete research methods should be based. I explore how to evolution in economic geography by placing history in historical time and historical contexts. Accordingly, the concepts of path creation and path dependence should be used together in historical study. More important, the concept of path interdependence, which stresses the importance of the circumstances under which different processes and events are likely to occur, opens a new window on the temporal aspects of the world.Organizational ecology, fashion industry, creative industries, clusters, institutional lock-in

Socio-hydrological modelling: a review asking “why, what and how?”

Interactions between humans and the environment are occurring on a scale that has never previously been seen; the scale of human interaction with the water cycle, along with the coupling present between social and hydrological systems, means that decisions that impact water also impact people. Models are often used to assist in decision-making regarding hydrological systems, and so in order for effective decisions to be made regarding water resource management, these interactions and feedbacks should be accounted for in models used to analyse systems in which water and humans interact. This paper reviews literature surrounding aspects of socio-hydrological modelling. It begins with background information regarding the current state of socio-hydrology as a discipline, before covering reasons for modelling and potential applications. Some important concepts that underlie socio-hydrological modelling efforts are then discussed, including ways of viewing socio-hydrological systems, space and time in modelling, complexity, data and model conceptualisation. Several modelling approaches are described, the stages in their development detailed and their applicability to socio-hydrological cases discussed. Gaps in research are then highlighted to guide directions for future research. The review of literature suggests that the nature of socio-hydrological study, being interdisciplinary, focusing on complex interactions between human and natural systems, and dealing with long horizons, is such that modelling will always present a challenge; it is, however, the task of the modeller to use the wide range of tools afforded to them to overcome these challenges as much as possible. The focus in socio-hydrology is on understanding the human–water system in a holistic sense, which differs from the problem solving focus of other water management fields, and as such models in socio-hydrology should be developed with a view to gaining new insight into these dynamics. There is an essential choice that socio-hydrological modellers face in deciding between representing individual system processes or viewing the system from a more abstracted level and modelling it as such; using these different approaches has implications for model development, applicability and the insight that they are capable of giving, and so the decision regarding how to model the system requires thorough consideration of, among other things, the nature of understanding that is sought

Integrated modelling of social-ecological systems for climate change adaptation

Analysis of climate change risks in support of policymakers to set effective adaptation policies requires an innovative yet rigorous approach towards integrated modelling (IM) of social-ecological systems (SES). Despite continuous advances, IM still faces various challenges that span through both unresolved methodological issues as well as data requirements. On the methodological side, significant improvements have been made for better understanding the dynamics of complex social and ecological systems, but still, the literature and proposed solutions are fragmented. This paper explores available modelling approaches suitable for long-term analysis of SES for supporting climate change adaptation (CCA). It proposes their classification into seven groups, identifies their main strengths and limitations, and lists current data sources of greatest interest. Upon that synthesis, the paper identifies directions for orienting the development of innovative IM, for improved analysis and management of socio-economic systems, thus providing better foundations for effective CCA

The Evolutionary Dynamics of Infectious Diseases on an Unstable Planet: Insights from Modeling the Stockholm Paradigm

Emerging infectious diseases (EIDs) are, besides a question of food safety and public health, an ecological and evolutionary issue. The recognition of this condition combined with the accumulation of evidence that pathogens are not specialists in their original hosts evidences the need for understanding how the dynamics of interaction between pathogens and hosts occurs. The Stockholm Paradigm (SP) provides the theoretical fundaments to understand the dynamics of diseases and design proactive measures to avoid the emergence and reemergence of infectious diseases. In this review, we revisit the models that evaluate several aspects of the proposed dynamics of the SP, including the complexity nature of the elements that have been associated with this new framework for the evolution of associations. We integrate the results from these studies into a putative dynamic of infectious diseases, discuss subordinate elements of this dynamic, and provide suggestions on how to integrate these findings into the DAMA (Document, Assess, Monitor, Act) protocol
