Temporal stability and psychological foundations of cooperation preferences

A core element of economic theory is the assumption of stable preferences. We test this assumption in public goods games by repeatedly eliciting cooperation preferences in a fixed subject pool over a period of five months. We find that cooperation preferences are very stable at the aggregate level, but less so at the individual level. Nevertheless, individual preferences are sufficiently stable to predict future behavior fairly accurately. Our results also provide evidence on the psychological foundations of cooperation preferences. The personality dimension 'Agreeableness' is closely related to both the type and the stability of cooperation preferences.Social preferences, preference stability, conditional cooperation, free riding, personality, Big-Five.

Vocational Training in Higher Education: A Learning Centred Approach to Integrating ‘Educultures’

The goal of this effort is to make plain any overlap between Post-Secondary Mechanical Technician Standards and Plumbing Apprenticeship Curriculum Standards. We\u27ll investigate whether the overlap is significant enough to create a modern and updated classroom learning template. Mechanical Technician programs are generally 56 weeks in length. A Plumbing Apprenticeship is significantly longer. The essential question is: What portion of Technician Education equates to the first 100 to 200 weeks of Apprenticeship Training. If enough meaningful and actionable overlaps do exist there may be opportunities to strengthen real-world-connections to in-school lectures and labs. The two key Standards that will be investigated include: 1) Ministry of Advanced Education and Skills Development - Mechanical Techniques / Technician Program Standards. (Queens Printer for Ontario, 2010) 2) Ontario College of Trades - Levels One / Two of the Plumbing Apprenticeship Standards. (Queens Printer for Ontario, 2007) In the making of a Standards integration framework, a third -daunting- aspect must also be discussed. That is, how does the association between the Standards suit classroom stakeholders? Where primary technologies such as Plumbing are concerned, the teaching and learning environment can vary quite a lot. Among others, the differences between applied and liberal education and, rural and urban dwellers are notable, as is male verses female engagement in the trade. If a template can meet just a few of the challenges -by being classroom-usable in both Attawapiskat and Brampton- The Author deem the results of this effort a success

Heat buffers improve capacity and exploitation degree of geothermal energy sources

This research focuses on the role of heat buffers to support optimal use of combinations of traditional and renewable heat sources like geothermal heat for greenhouse heating. The objective was to determine the contribution of heat buffers to effective new combinations of resources that satisfy greenhouse heat, carbon dioxide and electricity demand at minimum cost. Tank buffers, basement buffers and aquifers were considered as short and long term buffers. Simulations were carried out for a 10ha sweet pepper and a 30ha tomato greenhouse (15ha intensively lighted). Standard heating systems based on central boiler and co-generation were used as a reference and compared with combinations of boilers, co-generators, geothermal heat and heat buffer strategies. Crop production and greenhouse climate were simulated and resource demand determined for normal greenhouse operation. A linear programming algorithm was used to apply resources and equipment available to the model at minimum cost. Results show that heat buffers help to reduce the required capacity of a geothermal heat source, and increase both the utilisation degree of the source and the cover percentage of greenhouse heat demand. The technically most feasible solution for long term buffering was the basement buffer which allows high buffer volumes without loss of useful space and heat loss contributes to greenhouse heating, however this solution was economically not feasible. Also the deep aquifer was a good option, however exploitation risks and manageability are potential problems. Integration of geothermal heat with other sources resulted in the best solutions that were both technically and economically feasible. Simulation showed at gas price level 30¿ct.m-3, that geothermal heat was cheaper than central boiler and even co-generation heat when hours of operation exceed 1000h.y-1. Instead of using large buffers, peak loads can also be covered by central boilers. Simulated solutions reduced gas consumption with 60 to 95%
