Reducing Greenhouse Gas Emissions through Behavioral Change : An Assessment of Past Research On Energy Use, Transportation and Water Consumption

17 p.Behavioral changes are certain to be an important component in reducing greenhouse gas emissions (GHG) and combating climate change. However, relatively little research has been done to clarify what is known about the ability to motivate people to change their behavior in a way that reduces GHGs. This report provides a preliminary overview of the existing research on this critical question. It then provides a framework for thinking about how to plan and execute GHG reducing behavioral change interventions. This is not a comprehensive assessment. Instead, it highlights some of the most readily available relevant research on behavioral change and GHG reductions in three domains: energy use, transportation, and water consumption. Our intent is to offer a clear, simple, basic guide that can serve as a starting point for implementation of behavioral change programs and for further research into the topic

A longitudinal evaluation of a project-based learning initiative in an engineering undergraduate programme

Project-based learning (PBL) is a well-known student-centred methodology for engineering design education. The methodology claims to offer a number of educational benefits. This paper evaluates the student perceptions of the initial and second offering of a first-year design unit at Griffith University in Australia. It builds on an earlier evaluation conducted after the initial offering of the unit. It considers the implementation of the recommended changes. Evaluations of the two offerings reveal that students (in both the initial and second offering) generally enjoyed the experience, but that the second offering was found to be a significantly more enjoyable learning experience. Students in the second offering also reported a significantly better understanding of what they needed to do for the design projects and where to find the requisite information. The oral presentation aspect of the initial and second offerings received the lowest satisfaction rating. The inclusion (and delivery) of the computer-aided drawing component of the unit is seen as a positive aspect by some students, but many others comment on it negatively. The best aspects of the PBL unit and those aspects needing further improvement were similar to the findings of other investigations documented in the literature

Justifying the Special Theory of Relativity with Unconceived Methods

Many realists argue that present scientific theories will not follow the fate of past scientific theories because the former are more successful than the latter. Critics object that realists need to show that present theories have reached the level of success that warrants their truth. I reply that the special theory of relativity has been repeatedly reinforced by unconceived scientific methods, so it will be reinforced by infinitely many unconceived scientific methods. This argument for the special theory of relativity overcomes the critics’ objection, and has advantages over the no-miracle argument and the selective induction for it

Refutations of the Two Pessimistic Inductions

Both the pessimistic inductions over scientific theories and over scientists are built upon what I call proportional pessimism: as theories are discarded, the inductive rationale for concluding that the next theories will be discarded grows stronger. I argue that proportional pessimism clashes with the fact that present theories are more successful than past theories, and with the implications of the assumptions that there are finitely and infinitely many unconceived alternatives. Therefore, the two pessimistic inductions collapse along with proportional pessimism

Equality and the Digital Divide

Although distribution of computers and Internet access is important in equalizing information access, this article considers the concept of digital literacy. People not only need access to information, but an understanding of what to do with the knowledge acquired. Explore with Professor Doppelt the idea that the digital divide is a new aspect to the literacy divide, and the crucial role that education in public schools plays in equalizing opportunity
