Reorganization of supply chains as a key for the envision of socio-technical transitions. The case of tourism
No full textAs stressed by the literature on technological change, not only production and logistics activities take place along supply chains, but also innovation processes. It is then surprising that in the extensive research field of socio-technical transitions, the supply chain – and its actors – are seldom considered as a key point of the analysis. This paper aims at filling this gap of the literature by showing that the understanding of the on-going reorganization of supply chains – and the possible conflicts between actors it brings along – is a key to envisage socio-technical transitions and scenarios. A specific attention is given to conflicts between new entrants, that bring along a disrupting innovation, and dominant incumbents that resist to change. Tourism is proposed as a reference case just because the on-going radical change of its supply chain of vertically interrelated industries is currently led by a bunch of internet-based new entrants. Direct interviews to tourism experts and operators are used to build and evaluate three alternative socio-technical scenarios of tourism
The dynamics of social capital during public participation: new knowledge from an on-going monitoring
No full textThe mutual impacts between public participation and social capital has been thoroughly investigated, but little is known about the dynamics of social capital during a participative process. To fill such a gap, an ad-hoc monitoring system of social capital was implemented along an actual participative procedure about the future of an University site. Results show that: i) social capital evolution can follow non-monotonic patterns; ii) different dynamics of social interaction may occur that impact the quality of participation; iii) different participatory tools may lead to different dynamics of social capital; iv) repeated measurements of social capital generate a memory effect which reduces the variation of social capital itself. We also describe relevant drawbacks (resource consuming activities, reduced number of participants, etc.) which may reduce the applicability of the proposed approach. We conclude discussing when an on-going monitoring process is worth to be implemented, and we also describe some relevant side results for those interested to the issue of public participation: i) the announcement of the procedure already generated relevant individual learning; ii) the individual interviews were recognized as an essential learning moment, so we suggest including them into the design of any participative process
The dynamics of trust during public participation
No full textLiterature often relies on ex post feedbacks from participants to investigate how public participation affects social capital. However, some scholars suggest that the actual achievement of own interests might bias the participants' ex post perception. Therefore, we designed an on‐going evaluative system to monitor the dynamics of trust during public participation, and we tested it in a real case of engagement with local community of stakeholders. The evaluative system could track both processes of creation and destruction of trust over the time, designing complex patterns of evolutions. This study also provided hints for a more effective use of participatory tools
Mapping Sustainability Transitions. Networks of Innovators, Techno-economic competences and Political Discourses
No full textWith this book we have set ourselves an ambitious target: to provide the readers with a simple graphical tool – the socio-technical map – that may help them understand how the environmental sustainability of human activities may be reached. In other terms, we have tried to make simple a very complex process. To reach this goal we founded our work on the recently emerged research field of sustainability transitions (SusTrans). The starting point of the SusTran approach is that most of human needs are fulfilled by systems which have proved to be environmentally unsustainable, and it is precisely for this reason that these systems should be radically changed. In other words: system innovation is at the heart of SusTrans.
Systems that fulfill human need feature two relevant characteristics which should be seriously taken into consideration when aiming at the ambitious goals of curbing greenhouse gas emissions and reducing all other environmental impacts of human activities. First characteristic: these systems are embedded in the very structure of our society. Behind each good and service we produce and consume every day one can find several interconnected elements: individuals and organizations, values and ideologies, technologies and infrastructures, markets and industries, rules and norms, and so forth. Thus the functioning of these systems simultaneously involves the cultural, institutional, technological and economic dimensions of human life: any attempt at reductionism – for example to the technological or economic dimension of such systems – is not correct. Second characteristic: these systems are continuously changing. Their dynamics is generated by a process of structured action: systems are changed by human agents, but their action is in turn conditioned by the very structure of systems. Moreover – and maybe more important here – the outcome of such a process is uncertain: no change is known ex-ante, but it emerges as the (sometimes unintended) result of human action. This is why any attempt to describe system innovation as the result of a choice between given alternatives is not correct. If we keep in mind these two characteristics, we realize that an effective approach to environmental sustainability must be: 1) systemic, that is, able to consider all dimensions of innovation, not only technologies or markets, but also behavior, rules, discourses, policies, etc.; 2) dynamic, that is, able to understand how new systems emerge through the alignment of innovations as they are generated.
In order to meet these two requirements, the SusTran approach mostly refers to the socio-technical (ST) analysis of innovations. Here any societal function is fulfilled by one or more ST systems, and its evolution is strongly affected by the interaction between a stable and dominant ST system and other existing or emerging ST systems. Each of these ST systems is supported by a network of agents interested in its reproduction. Following ST theories and concepts, a SusTran can be represented as a ST transition to sustainability: a process of radical change where the current dominant position of an unsustainable ST system is destabilized and took over by a new – and environmentally sustainable – ST system. In such a representation innovators play a key role: both those innovating to protect a dominant position, and those innovating to take it over. Such a competition between alternative ST systems – and their supporting networks of innovators – is strongly affected by policies. In particular, a ST system is holding a dominant position also because it was able to gain support from favorable policies that now protect the status quo. This is why a SusTran may not take place without new and specific policies that: a) help emerging ST systems to consolidate, and b) destabilize the dominant ST system. This in turn implies that the competition between alternative networks of innovators taking place along a SusTran is not only about technological leadership and market power; it also refers to the ability of influencing public debates, political agendas and actual policies. In other terms: political innovators and political innovations are relevant features of any SusTran.
Summing up: SusTrans are complex processes. They feature systemic changes, structured action, innovation-driven dynamics and – last but not least – competition on multiple dimension. As stated at the beginning of this Preface, the ambitious goal of this book is to provide the reader with a simple graphic tool – the socio-technical map (ST-map) – which can be used to represent a SusTran without renouncing to the understanding of its complexity. In particular, with this book any scholar or practitioner interested to the issue of sustainability will be able to understand how the current situation of any societal function may give place to different ST transition pathways. The dynamics of the relevant networks of innovators – and their technological, market and political strategies – will be the key variables to assess the likelihood of the resulting alternative scenarios. The ST-map can also be used to understand which policies are deemed necessary to support those ST transition pathways – if any – that can be considered as SusTrans.
The book is divided as follows. In Chapter 1 the essential basic concepts that are needed to build a ST-map will be presented; a specific attention will be given to the definition of ST systems and SusTrans, and to the role played by network of innovators. In Chapter 2 we will explain in details how to build a ST-map and how to use it to generate alternative ST transition pathways; in particular, we will see how to position in the ST-map all relevant networks of innovators and how to forecast their future dynamics. In Chapters 4-7 the results of some case studies will be provided: the societal functions of feeding, mobility and lighting were analyzed in order to ascertain if the ST-map can be adapted to different situations. With the case of food we verified that the ST-map is able to represent a transition featuring different (if not conflicting) visions of sustainability; with the cases of mobility we found that both global and local dynamics can be considered starting from the same ST-map; in the case of lighting the ST-map proved useful to generate new knowledge on the overall dynamics of dominant ST-systems and policies. On the whole, case studies also confirmed that the ST-map is a more appropriate and powerful analytic tool for prospective rather than retrospective studies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
