AbstractThe compelling need to tackle climate change is well-established. It is a challenge which is being faced by all nations. This requires an approach which is truly inter-disciplinary in nature, drawing on the expertise of politicians, social scientists, and technologists. We report how the pace of the energy transition can be influenced significantly by both the operation of societal barriers, and by policy actions aimed at reducing these effects. Using the case study of South Africa, a suite of interviews has been conducted with diverse energy interests, to develop and analyse four key issues pertinent to the energy transition there. We do so primarily through the lens of delivering energy justice to that society. In doing so, we emphasise the need to monitor, model, and modify the dynamic characteristic of the energy transition process and the delivery of energy justice; a static approach which ignores the fluid nature of transition will be insufficient. We conclude that the South African fossil fuel industry is still impeding the development of the country’s renewable resources, and the price of doing so is being met by those living in townships and in rural areas.

Two Degree Of Freedom

In this paper, bifurcations of a nonlinear two-degree-of-freedom system subjected to a narrow-band stochastic excitation are investigated. Under the assumption that the correlation time greatly exceeds the relaxation time, a quasi-static approach combined with averaging method is adopted to obtain the bifurcation equations, and the singularity theory is applied to analyze the bifurcations. It is demonstrated that bifurcation patterns jump from one to another due to the influence of a random parameter. The probabilities of the jumping bifurcation patterns are given.

Cross Fertilization

- Heterodox environmental economics is mainly based on non-mainstream economic theories; in particular it refers to two classic strands of economics (and to their recent revival and cross-fertilization): institutional economics and Schumpeterian economics. Starting from these theoretical foundations, heterodox environmental economics radically differs from the mainstream (market-centred and static) approach to positive and normative environmental economics. Three basic concepts are at the hearth of such a different vision: resource regimes, as institutional structures established to regulate access to natural resources and their use; environmental appraisals, as "value articulating" institutions conditioned by the incommensurability of conflicting values; "sociotechnical" transitions, as dynamic processes that are needed to unlock existing unsustainable technologies, institutions and values. These considerations are not sufficient to say that heterodox environmental economics has already become a paradigm; a stable community of researchers defining themselves as ‘heterodox environmental economists' still does not exist. Time will tell if some emerging connections between different research groups will generate the social core of a nascent paradigm.Keywords: environmental economics; heterodox economics; institutional economics; evolutionary theories of economic changeJEL classification: B52; Q50

Static Approach

The aim of this paper is to study the dynamics of a floating body with characteristics comparable to a point absorber wave energy converter with different mooring systems, in geometrical configuration or in the materials. To this purpose, the dynamics of a moored buoy is investigated. The point absorber is modeled as a spherical buoy in plane two-dimensional motion, and it is studied under the action of irregular unidirectional wind-generated waves, moored to the seabed by means of one, two or three mooring lines. Two different sets of moorings are considered, and typical wires and chains used in offshore technology are considered, leading to a total of 6 case studies. A quasi-static approach is used for modeling the restoring forces needed to keep buoy into station, using an innovative iterative procedure able to predict for each time instant and for each cable the lay down length of the cable, being each mooring line allowed to be taut or slack. Approaches in the time and frequency domains are used to obtain the system responses in intermediate waters, where these facilities are usually installed. Results for all case studies are compared both in terms of statistics of response and tensions on the top of the cable.

Over Time

Much of organizational justice research has tended to take a static approach, linking employees’ contemporaneous justice levels to outcomes of interest. In the present study, we tested a dynamic model emphasizing the interactive influences of both justice levels and trajectories for predicting behavioral social exchange outcomes. Specifically, our model posited both main effects and interactions between present justice levels and past justice changes over time in predicting helping behavior and voluntary turnover behavior. Data over four yearly measurement periods from 4,348 employees of a banking organization generally supported the notion that justice trajectories interact with absolute levels to predict both outcomes. Together, the findings highlight how employees invoke present fairness evaluations within the context of past fairness trends—rather than either in isolation—to inform decisions about behaviorally reciprocating at work.
