Governance of Environment-Enhancing Technical change - past experiences and suggestions for improvement

There is much talk about environmental policies being faulty. Past policies are being criticisedfor failing to achieve environmental goals (the environmentalist complaint), for being overlyexpensive (the industrialist complaint) and for failing to encourage innovation and dynamicefficiency (the complaint of economists dealing with innovation). This paper looks at theinnovation and technology adoption effects of past environmental policies. It finds indeed fewexamples of environmental policies that stimulated innovation. The common technologyresponse is the use of expensive end-of-pipe solutions and incremental process changesoffering limited environmental gains. This begs the question: why did the policies fail topromote more radical innovation and dynamic efficiency? One explanation—well-recognisedin the economic literature—is the capture of government policies by special interests. Thispaper offers a second explanation—based on innovation and technology adoption studies—which says that in order to have a decisive and socially beneficial influence policy instrumentsmust be fine-tuned to the circumstances in which sociotechnical change processes occur and tipthe balance. Within this alternative view, the starting point of government interventions is thecapabilities, interests, interdependencies and games of social actors around an environmentalproblem instead of the set of environmental policy instruments for achieving an environmentalgoal. The paper sees a need for government authorities to be explicitly concerned with technicalchange (rather than implicitly through a change in the economic frame conditions) and to beconcerned with institutional arrangements beyond the choice of policy instruments, and act as achange agent. This requires different roles for policy makers: that of a sponsor, planner,regulator, matchmaker, alignment actor and ‘creative game regulator’. The paper offers twoperspectives on environmental policy: an instrument one and a modulation one. The latter isespecially important for promoting innovation and bringing about radical change, somethingwhich is very difficult with traditional regulatory instruments. Instruments for promotingenvironment-enhancing technical change are appraised and suggestions are offered for thepurposes for which different policy instruments may be used in differing economic contexts.environmental economics ;

Gunrock: GPU Graph Analytics

For large-scale graph analytics on the GPU, the irregularity of data access and control flow, and the complexity of programming GPUs, have presented two significant challenges to developing a programmable high-performance graph library. "Gunrock", our graph-processing system designed specifically for the GPU, uses a high-level, bulk-synchronous, data-centric abstraction focused on operations on a vertex or edge frontier. Gunrock achieves a balance between performance and expressiveness by coupling high performance GPU computing primitives and optimization strategies with a high-level programming model that allows programmers to quickly develop new graph primitives with small code size and minimal GPU programming knowledge. We characterize the performance of various optimization strategies and evaluate Gunrock's overall performance on different GPU architectures on a wide range of graph primitives that span from traversal-based algorithms and ranking algorithms, to triangle counting and bipartite-graph-based algorithms. The results show that on a single GPU, Gunrock has on average at least an order of magnitude speedup over Boost and PowerGraph, comparable performance to the fastest GPU hardwired primitives and CPU shared-memory graph libraries such as Ligra and Galois, and better performance than any other GPU high-level graph library.Comment: 52 pages, invited paper to ACM Transactions on Parallel Computing (TOPC), an extended version of PPoPP'16 paper "Gunrock: A High-Performance Graph Processing Library on the GPU

Efficient and accurate log-L\'evy approximations to L\'evy driven LIBOR models

The LIBOR market model is very popular for pricing interest rate derivatives, but is known to have several pitfalls. In addition, if the model is driven by a jump process, then the complexity of the drift term is growing exponentially fast (as a function of the tenor length). In this work, we consider a L\'evy-driven LIBOR model and aim at developing accurate and efficient log-L\'evy approximations for the dynamics of the rates. The approximations are based on truncation of the drift term and Picard approximation of suitable processes. Numerical experiments for FRAs, caps, swaptions and sticky ratchet caps show that the approximations perform very well. In addition, we also consider the log-L\'evy approximation of annuities, which offers good approximations for high volatility regimes.Comment: 32 pages, 21 figures. Added an example of a path-dependent option (sticky ratchet caplet). Forthcoming in the Journal of Computational Financ

The societal embedding of sustainable Product-Service Systems: Looking for synergies between strategic design and transition studies

Copyright @ 2014 Greenleaf Publishing.Eco-efficient Product-Service System (PSS) innovations represent a promising approach to sustainability, but their implementation and diffusion is hindered by several cultural, corporate and regulative barriers. Hence, an important challenge is not only to conceive sustainable PSS concepts, but also to understand how to manage, support and orient the introduction and diffusion of these concepts. Building upon recent advances in the innovation studies field (in particular the contributions from transition studies) this chapter puts forward a conceptual framework for the introduction and scaling-up of eco-efficient PSSs. A key role is given to the implementation of socio-technical experiments: protected spaces where radical innovations can be tested, become more mature, and potentially challenge and change dominant socio-technical practices, habits and institutions. Starting from these considerations this chapter investigates the potential contribution that a strategic design approach can make to stimulating and supporting the societal embedding of eco-efficient PSS innovations. A new strategic design role thus emerges, a role in which the ideation and development of sustainable PSS concepts is coupled with the designing of appropriate transition paths to gradually incubate, introduce and diffuse these concepts. Starting from these considerations the chapter outlines and discusses the new design approach and capabilities required by strategic designers

Challenges and Prospects for the EU’s Area of Freedom, Security and Justice: Recommendations to the European Commission for the Stockholm Programme. CEPS Working Document No. 313, 16 April 2009

The upcoming Swedish presidency of the EU will be in charge of adopting the next multi-annual programme on an Area of Freedom, Security and Justice (AFSJ), during its tenure in the second half of 2009. As the successor of the 2004 Hague Programme, it has already been informally baptised as the Stockholm Programme and will present the EU’s policy roadmap and legislative timetable over these policies for the next five years. It is therefore a critical time to reflect on the achievements and shortcomings affecting the role that the European Commission’s Directorate-General of Justice, Freedom and Security (DG JFS) has played during the last five years in light of the degree of policy convergence achieved so far. This Working Document aims at putting forward a set of policy recommendations for the DG JFS to take into consideration as it develops and consolidates its future policy strategies, while duly ensuring the legitimacy and credibility of the EU’s AFSJ within and outside Europe

Understanding temporal rhythms and travel behaviour at destinations: Potential ways to achieve more sustainable travel

This paper analyses the roles played by time in destination-based travel behaviour. It contrasts clock time's linear view of time with fragmented time, instantaneous time, fluid time and flow, time out and the multiple temporalities of tourism experiences. It explores temporal issues in a destination travel context, using qualitative techniques. Data were captured using diary photography, diary-interview method with tourists at a rural destination; their spatial and temporal patterns were captured using a purpose built smartphone app. The analysis revealed three temporal themes influencing travel behaviour: time fluidity; daily and place-related rhythms; and control of time. Three key messages emerge for future sustainable tourist destination-based travel systems. Given the strong desire for temporal fluidity, transport systems should evolve beyond clock-time regimes. Second, temporal forces favour personal modes of transport (car, walk, cycle), especially in rural areas where public transport cannot offer flexibility. Third, the car is personalised and perceived to optimise travel fluidity and speed, but is currently unsustainable. Imaginative initiatives, using new mobile media technology can offer new positive and proactive car travel, utilising spare public and private vehicle capacity. Research is needed to implement mechanisms for individualised space-time scheduling and collective vehicle use strategies. © 2013 Copyright Taylor and Francis Group, LLC

Struggling to 'fit in': On belonging and the ethics of sharing in project teams

This paper explores the links between belonging and ethics, which remain largely underdeveloped in project studies and are overlooked in everyday practice of managing projects. It focuses on belonging as the process articulating identity-construction of an inter-organisational project team from a global management consulting firm that was working in IS design. As the team?s experienced ?sense of place?, belonging becomes the space which highlights preferred affiliations and exposes how ? individually and collectively ? ethics are played out in the context of the management of projects. Four in situ belonging-narratives (of opposition, pragmatism, reflexivity, and the habitual narrative) represent ethics as part of lived action and of a life-world that emerge from deconstructing and reconstructing ?the team? and an ideal worker in projects. The team?s struggles to ?fit in? were experienced both when resisting and when collaborating with the dominant collective narrative of belonging. Modes of belonging are constituted in the relationship between self, others, and ?otherness?, creating a situated ethical imagination of how to ?be professional?. Implications concern the politics of belonging and call for a renewed practical ethics that engages with the social nature of ?being?, to change the current view of professional identities in projects

Building sustainable business development services : empirical evidence from Kenya

Paper presented at the International Academy of African Business and Development (IAABD) Conference, 19thMay-23rd May 2009, Kampala, Uganda,This is a PhD thesis that is ongoing. In this paper the authors investigates how sustainability of BDS can be explained; why some BDS providers succeed while others don’t; what the successful BDS providers do differently from those who are not as successful. Grounded Theory is used and justification for its use is given. Data collection and analysis is still going on. Preliminary findings from the data so far collected and analyzed show that what makes sustainable BDS seems to vary from one individual provider or organization to another depending on the motivates for venturing into the business, the personal attributes of the provider, the business approach that the provider takes and on the prevailing external factors. Furthermore it depends on how sustainability has been defined.This is a PhD thesis that is ongoing.
