Tuition fees and social segregation: lessons from a natural experiment at the University of Paris 9-Dauphine

Using a natural experiment, a sharp rise in tuition fees in some of the programmes at the University of Paris 9-Dauphine, we study the impact of tuition fees on students’ pathways, and outcomes. We apply an optimal matching method to the national database of students’ registrations (SISE) to define a typology of pathways. We then use a nonordered multinomial logit model to evaluate the impact of the rise in tuition fees on the types of pathways selected by the university. We show that there is a significant impact on these pathways. The increase in tuition fees reduces geographic and social mobility, thereby accentuating the phenomena of social segregation. Furthermore, contrary to what some of the studies assert, the rise does not appear to encourage greater effort: we find no impact on the graduation success rate.     

Designing and evaluating sustainable development pathways for semi‐subsistence crop–livestock systems: lessons from Kenya

Achieving the Sustainable Development Goals (SDGs) in African agriculture requires a better understanding why high levels of poverty and resource degradation persist in African agriculture despite decades of policy interventions and development projects. In this article, we hypothesize that policies need to account for the key features of the semi‐subsistence crop–livestock systems (CLS) in the region to become effective. The semi‐subsistence CLS are characterized by a high degree of biophysical and economic heterogeneity and a complex, diversified production system involving a combination of subsistence and cash crops with livestock. We investigated the potential for interventions proposed by the Government of Kenya to meet the SDGs by 2030. The analysis uses an integrated modeling approach designed to deal with the key features of these systems. A strategy that stimulates rural development, increases farm size to a sustainable level, and reduces distortions and inefficiencies in input and output markets could lead to a sustainable development pathway and achieve the SDGs for rural households dependent on CLS.     

Drivers and barriers to the adoption and diffusion of Sustainable Jet Fuel (SJF) in the U.S. Pacific Northwest

Sustainable Jet Fuel (SJF) represents an important component of the airline industry's strategy to simultaneously reduce GHG emissions while meeting a growing demand for international air travel. SJFs also have the potential to provide fuel supply diversification and security, enhance fuel price stability and provide regional/rural economic development benefits. This paper measures and ranks perceived drivers and barriers to an economically viable SJF industry in a unique U.S. region, the U.S. Pacific Northwest (PNW), through personal interviews with key aviation fuel supply chain stakeholders conducted from June to September 2015. In addition to providing a fertile arena for this first effort to systematically assess these drivers and barriers, the U.S. PNW is unique due to the region's long strategic focus on aviation innovation and its importance to the regional economy, the seminal efforts in the region to outline a path forward on SJF beginning in 2010, and the relatively small population spread over a large geographic area with a limited number of “hub” airport nodes which geographically concentrates aviation fuel demand and distribution. Nineteen stakeholder interviewees acknowledge that, in order for regional SJF adoption-diffusion to occur, airline jet fuel buyers must drive the process, particularly as they deal with greenhouse gas (GHG) emission issues and related policy considerations. Important perceived barriers to SJF industry scale-up in the U.S. PNW include the high production costs of SJF and related issues, such as fuel logistics and quality control in the transport, storage, and blending of SJFs. Perceptions around chain-of-custody issues, such as blending, tracking, and crediting of SJFs and future SJF market share projections for the year 2030 were also examined. Incorporating stakeholder input into discussions about adding blended SJF into the U.S. aviation fuel supply provides needed insight for the biofuels industry, policymakers, and researchers.     

Modelling the Risks Associated with the Increased Importation of Fresh Produce from Emerging Supply Sources Outside the EU to the UK

The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic.     

Theoretical activity in sustainable tourism research

There is growing recognition in tourism and sustainable tourism research of the need for a fuller engagement in theoretical activity. The paper examines how different research strategies in recent articles on sustainable tourism have advanced theoretical understanding in this research field. The articles advance thinking through ideas and concepts connected with political ecology, mobilities, transition pathways, and behavioural and systems change. They are evaluated using a typology of research strategies associated with theoretical work, using a broad perspective on this work. The research strategy typology was developed for the paper, and it is explained and illustrated. While the papers on sustainable tourism use a range of strategies associated with theoretical activity, there is only limited engagement with “big” social theories.

The Development of the Institutional Investor: The Case of Australian Life Insurers 1945–85

This paper considers the post‐war development of asset management practices among Australian life insurers, which have historically been among the largest institutional investors in Australia. A complex process of adaptation and organisational restructuring allowed life insurers to transform from basic investors of policy‐holders’ funds to large multifaceted institutional investors in just three decades. Three stages in the development of investment practices are identified. These phases trace the process of expanding existing knowledge bases; diversification; and the acquisition of new skills; consolidation and the integration of these skills into institutional structures; thus completing one cycle of organisational learning and setting the stage for the next.

Uncovering Micro‐Practices and Pathways of Engagement That Scale Up Social‐Driven Collaborations: A Practice View of Power

This paper explores how large‐scale social‐driven collaborations might grow in scale and help promote political change. We present the results of a qualitative investigation of a complex platform where multiple and hybrid collaborations co‐exist and where civil society plays a central role. Based on a longitudinal comparative case study, we draw a processual model describing micro‐practices and pathways of engagement. We show that the emergence of these collaborations requires a new type of convener, one that is able to manage the interplay between the sharing/co‐creation of abundant resources and the coordinated decentralization of informal authority. Our study extends existing debates on the role of resources and authority, showing the complementarity between possession and practice perspectives of power. Finally, we identified synergies between collaboration and social movement literatures, particularly showing that large‐scale collaborations could be mobilized to refine social movement agendas and achieve more purposive collective action.     

Innovation intermediary challenging the energy incumbent: enactment of local socio-technical transition pathways by destabilisation of regime rules

ABSTRACT

The energy sector needs to transform towards sustainability. The multi-level perspective on sociotechnical transitions is embracing an enactment perspective, which focuses on the agency of various actors in shifting transitions pathways but has yet to study local urban experiments from such an enactment perspective. Our empirical research examines an innovation intermediary’s work in destabilising the regime rules in relation to the local energy incumbent company in Helsinki, Finland. Our paper seeks answers to the questions: How does the collaboration of the intermediary and the local energy company unfold? What are the impacts of the intermediary work on the local energy company in terms of enactment of transition pathways and what are the mechanisms causing the impact? Our research shows that the intermediary contributes to the transition by disturbing existing rules, structures, practices and networks by convening innovation champions from different constituencies, renegotiating regime rules and disrupting existing R&D alliances.
