    "Jahresgabe 1969 für die Mitglieder der Gesellschaft der Freunde und Förderer der Folkwangschulen e.V." This work is the production of Rehagel in his sixth semester at this school of the arts. I take it that we are dealing with the most famous school with a name like this, namely in Essen. The ten woodcuts are strong. My prize among them goes to the image of the miser kneeling beside the hole in which he had hid his riches. In the background someone slinks away with something in his hand. Well done! About 10" square. This collection is great for finding and bringing together rarities like this pamphlet.Language note: German1 of 750No Autho

    In this essay written at boarding school, Donald, aged seventeen, describes a school trip to Essen, in Germany, to see the work of a Dr Schmidt who, in Winnicott’s view, is an enlightened town planner who considers the needs of the men women and children of his town with great care. Winnicott enthusiastically reports Schmidt’s care of the health and safekeeping of the many inhabitants of Essen, with implications for the same approach in the UK.</p

    Evaluating Rural Electrification Projects - Methodological Approaches

    No full text
    In recent years, the international community has expanded efforts in programme evaluation to improve the accountability of development projects. This paper presents approaches to implementing state-of-the-art evaluations in rural electrification projects, taking into account specific challenges that researchers face in such interventions. Furthermore, it suggests a particular approach to assess impacts before an intervention is implemented by surveying the yet non-electrified target region of the project and, in addition, an already electrified region. Besides delivering robust evidence on impacts, results from such ex-ante evaluations provide insights for the project design, thereby reducing the gap between evaluation researchers and practitioners.Impact evaluation, ex-ante impact assessment, electricity access, rural development

    A mathematical programming model for optimal fleet management of electric car-sharing systems with Vehicle-to-Grid operations

    Electric car-sharing systems have attracted large attention in recent years as a new business model for achieving both economic and environmental benefits in urban areas. Among different types, the one considered in this paper is the so-called one-way car-sharing system whereby a user can begin and end a trip at any station of the system. At the same time, the Vehicle-to-Grid (V2G) concept is emerging as a possible innovative solution for smart power grid control. A management system that combines car-sharing system operations and V2G technology is a recent challenge for academia and industry. In this work, a mixed integer linear programming formulation is proposed to find the optimal management of electric vehicles in a one-way car-sharing system integrated with V2G technology. The proposed mathematical model allows finding the optimal start-of-day electric vehicles distribution that maximizes the total revenue obtained from system users and V2G profits through daily electric vehicles charging/discharging schedules. These schedules are based on mean daily users' electric vehicles requests and electricity prices. The model can be applied to evaluate the possible average daily profitability of V2G operations. In order to test the model performance, we applied it to a small-size test network and a real-size test network (the Delft network in the Netherlands). Under the model assumptions, the adoption of V2G technology allows to fully cover the daily charging costs due to users’ trips and to obtain V2G profits by taking advantage of electric vehicles unused time without significantly reducing the satisfied car-sharing system demand. Most of the energy purchased to charge the electric vehicles batteries is provided back to the grid during energy peak load demand, creating benefits also for energy providers.</p
