Exploring Standards of Rigour for Design Cases

Designers share their specialized knowledge by developing design cases, which we define as representations of design efforts and outcomes disseminated to peers. In the field of instructional design this practice is not well established. In addition, many fields in which design is practiced are examining how knowledge is built by designers, and considering the methods of research most applicable to building design knowledge. We consider design cases to be the method of dissemination for that design research which is wholly of apiece with the act of design (as compared to design research carried out in the process of designing or research on design). In considering the factors required to establish this practice, we understand the issue of rigour to be critical, since without standards by which to judge the rigour of a representation this form of knowledge building may always be undervalued in comparison to others. We look to naturalistic inquiry and action research to begin exploring how rigour might be approached in developing design cases, presenting from the perspective of instructional designers and hoping to engage designers from other fields insofar as these ideas are useful to them.

Aquatic Effects of a Localized Oil Spill on Lake Conway, AR and Its Tributaries

Oil spills, no matter where they occur, elicit environmental concern and avoiding these disasters should be a priority. Old pipelines that are not regularly maintained and carry large amounts of crude oil long distances are of particular concern. One such pipeline is the 65 year-old Pegasus pipeline owned by ExxonMobil. On March 29, 2013, 795,000 L of Wabasca Heavy Canadian crude oil spilled into a neighborhood of Mayflower, Arkansas, when the Pegasus pipeline ruptured. This spill led to the evacuation of many homes in the surrounding neighborhood. Drainage ditches in the affected neighborhood drained oil into a nearby cove of Lake Conway. This lake is popular for recreational fishing, thus concerns were raised not only about the potential effects of the oil spill on area residents, but also the lake and its biological communities. Ultimately, this project assessed the effect of the oil spill in water and sediment samples on freshwater test organisms. Samples were collected at 6 sites in the affected neighborhood and in Lake Conway. Chronic Whole Effluent Toxicity (WET) tests were performed on water samples using Pimephales promelas and Ceriodaphnia dubia. Acute sediment toxicity tests were performed using Chironomus dilutus. These tests measured sub-lethal toxicity in at least one of the sampled sites, indicating that further investigation of environmental after-effects is warranted

For the good of the group? Exploring group-level evolutionary adaptations using multilevel selection theory.

In this paper, we present an evolutionary framework, multilevel selection theory (MLS), that is highly amenable to existing social psychological theory and empiricism. MLS provides an interpretation of natural selection that shows how group-beneficial traits can evolve, a prevalent implication of social psychological data. We outline the theory and provide a number of example topics, focusing on prosociality, policing behavior, gossip, brainstorming, distributed cognition, and social identity. We also show that individual differences can produce important group-level outcomes depending on differential aggregation of individual types and relate this to the evolutionary dynamics underlying group traits. Drawing on existing work, we show how social psychologists can integrate this framework into their research program and suggest future directions for research

Providing the Scientific Backbone for Positive Psychology: A Multi-Level Conception of Human Thriving

This article begins with a consideration of what is missing in positive psychology – namely, an integrative framework within which to view the entire person, especially as nested within more-or-less supportive social contexts and cultures. Thus, I presented a multi-level hierarchical framework for considering and explaining human behavior, arguing that all levels of the framework are necessary for complete exposition. From this point of view, personality processes cannot be reduced to "mere" cognitive processes; there are trans-cognitive rules and laws operating at this higher level. I also considered a four level sub-framework within the personality level of analysis, consisting of organismic needs/characteristics, traits/dispositions, goals/intentions, and self/self-narratives. I contended that each of these spheres of the person operates via unique rules and regularities, processes that cannot be reduced to lower levels of analysis (such as biological, neurological, and cognitive levels of analysis). Finally, I described some recent research that simultaneously examines factors at multiple levels of the SLOPIC model, showing that each has influence for predicting SWB, and moreover, that all of these effects are mediated by basic need satisfaction. Hopefully this line of research will prove useful for other positive psychologists seeking "the big picture" on human flourishing

Educating Deaf Learners: A Book Review

Deaf education educator preparation programs are charged with serving their pre-service educators by providing current and relevant curricula in order to prepare them for the certification process and for the classroom environment. This book review was conducted in anticipation of possible adoption of a new text in the curriculum of a current Deaf and Hard of Hearing educator preparation program
