Promoting conceptual change of learning sorting algorithm through the diagnosis of mental models: The effects of gender and learning styles

It has been advocated that pedagogical content knowledge as well as subject matter knowledge are important for improving classroom instructions. To develop pedagogical content knowledge, it is argued that understanding of students' mental representations of concepts is deemed necessary. Yet assessing and comparing mental model of each individual is very tedious and time consuming. This study attempted to use gender and learning styles to associate mental models in learning sorting algorithm. The Gregorc Style Delineator (GSD) was used to measure learning styles of the participants. Mental models were assessed using the Pathfinder Scaling Algorithm (PSA). Results indicated that females showed greater similarity in mental models than males and concrete learners also exhibited closer resemblance to the expert mental model than abstract learners. These suggest that gender and learning styles can be meaningfully used to associate mental models in order to provide a group-based instead of individual-based diagnosis and thus promote conceptual change in learning. © 2009 Elsevier Ltd.

Predictors and outcomes of experiences deemed religious: A longitudinal investigation

Experiences deemed religious (EDRs) are events that a person regards as religious and/or supernatural. This study considered four such experiences—miraculous healing, glossolalia, unusual joy and peace during meditation or prayer, and prayer answered. We proposed a process model and conducted a longitudinal study to address three main research questions: (a) Who are more likely to have EDRs? (b) What effects would the experiences have on the person's subsequent spiritual and psychological conditions? (c) Are all EDRs alike? Findings suggest that EDRs can be predicted through certain common individual characteristics, such as vertical faith maturity (i.e., intimacy with the divine). However, there are also individual predictors that are EDR-specific. Regarding outcomes, the experience of unusual joy and peace during prayer and meditation heightens vertical faith maturity, motivates more religious practices, predicts better sleep quality at a later time, and perhaps improves quality of life. However, tongue speaking results in no change in any measured outcome variables. Neither does having prayers answered. Surprisingly, being healed from serious physical illness can have negative consequences. Results demonstrate that the EDRs should not be treated as the same when it comes to their antecedents and consequences.postprin

From a fossil-fuel to a biobased economy : the politics of industrial biotechnology

Industrial biotechnology involves the replacement of petrochemical processes and inputs with more energy-efficient and renewable biological ones. It is already being used in the production of biofuels and bioplastics and has been touted as a means by which modern economies can be shifted toward a more competitive, low-carbon growth model. This paper does two things. First, it outlines the policy framework established in the European Union and the narrative of a knowledge-based bioeconomy (KBBE) underpinning this. Second, it argues that the ‘win – win’ rhetoric contained within the KBBE narrative is misleading. Among the different groups commenting on the use of industrial biotechnology, the paper locates cleavages between farmers and agribusiness, between those convinced and those sceptical of environmental technofixes, and between procorporate and anticorporate NGOs. Taken together, they show the purported transition from a fossil-fuel to a bio-based economy to be a resolutely political one

Research and in situ conservation of owl monkeys enhances environmental law enforcement at the Colombian-Peruvian border

This study reports on impacts of illegal trade in owl monkeys (Aotus nancymaae, A. vociferans) for the biomedical research market in the Colombian-Peruvian Amazonian border. Through freedom of information requests and interviews with hunters we found that 912 owl monkeys, including A. nancymaae captured in Peru, were trapped over a 3-month period in 2012 to supply a malaria research facility based in Leticia, Colombia, which had trapping permits for the use of only 800 A. vociferans annually yet experimentation took place using A. nancymaae. High levels of extraction in Peru have had population-level impacts with significantly lower densities of Aotus spp. (3-24individuals/km2) compared to Colombian sites with low hunting pressure (26-44individuals/km2). Post-experimental release of this species in Colombian territory has created a new distribution whose status and impacts on resident populations of A. vociferans remain unknown. The trapping method has also had environmental impact, with loss of over 65,000 trees (including sleeping sites), annually. As Aotus species are registered under the Convention of International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II, international trade requires official permission and evidence that extraction does not impact wild populations. However, no official records exist and CITES legislation has failed, due principally to a lack of appropriate monitoring by national authorities responsible for compliance. Of further concern is that we had previously documented and reported the illegal trade to the appropriate governmental authorities yet still no action was taken-as demonstrated by the continuing trade in 2013. Enforcement eventually occurred when a non-governmental organization initiated legal action against organizations responsible. A successful second instance ruling by the Colombian State's Council in 2013 revoked trapping permits. Using the trade in owl monkeys as a case study we consider implementation, compliance, and enforcement of CITES in the border area to identify mechanisms to improve enforcement of environmental legislation.
