“Wind Power Energy Technology and Environmental Impact Assessment”

Power generation for the existing electrical grid is largely based on the combustion of fossil fuels. Global concerns have been raised regarding the environmental sustainability of the system due to life cycle impacts, including land losses from fuel extraction and impacts of combustion emissions. An approach to reduce carbon emissions of fossil fuel-based energy employs the conversion of wind energy to electrical energy. The work presented describes modern wind power plants and provides an environmental assessment of a representative wind park from a life cycle perspective. The empirical analysis uses commercially available data, as well as information from an existing wind power plant. The life cycle assessment (LCA) study for a modern wind farm in the northwestern U.S. found that environmental benefits of avoiding typical electricity production greatly outweigh the impacts due to wind turbine construction and maintenance. Effects of component reliability, varying capacity factors, and energy portfolio are explored.

“Withholding Requests For Disability Accommodation: The Influence Of Individual And Situational Attributes”

Prior research suggests that people with disabilities often do not request needed workplace accommodations, though relatively few studies address which factors influence the extent of such potentially self-limiting behavior. Drawing on workplace disability, help seeking, and social identity literature, this study proposes and tests a model of request withholding frequency using survey data from 279 people with hearing impairments. Consistent with expectations, older employees withheld requests less frequently; however, there was no main effect of gender. Moreover, the strength of the relationship between age and request withholding frequency was significantly weaker when the disability was more severe and when the age of disability onset was earlier. Similarly, disability severity influenced the strength of the relationship between gender and request withholding frequency, though the age of disability onset did not. These findings are consistent with social identity theory, in that those individual differences and disability attributes that shape social identities also appear to affect decisions to request disability accommodation. In practical terms, managers need to not only be supportive of disability accommodation requests but also recognize that some employees, such as young persons with disabilities, may need even more support, and support in a form that affirms or minimizes threats to other salient identities, such as their youth. Additional implications for management research and practice are discussed.

“World vs. Method: Educational Standard Formulation Impacts Document Retrieval”

Although initiatives are underway in the educational community to consolidate disparate collections of educational standards, little has been done to explore the impact of educational standard formulation on information retrieval. Recent research contrasts two categories of educational standards: ‘World’ (topical domain-related concepts) and ‘Method’ (investigative and epistemological principles). This paper explores the information retrieval implications of the World vs. Method distinction. We find that experts are more likely to agree about which educational resources align with a Method standard but that a typical automatic standard assignment tool is more likely to assign a World standard to an educational resource. Further, a text-based information retrieval system is more likely to be accurate in retrieving documents relevant to a World standard as compared to a Method standard. These findings have implications both for educational standard formulation (combining World and Method components in a standard may improve retrieval) and for digital library builders who want to help teachers identify useful, standards-aligned learning objects.
