A simple and versatile approach to incorporating basic optical microscopy in the undergraduate instrumental analysis laboratory is described. Attaching a miniature CCD spectrometer to the video port of a standard compound microscope yields a visible microspectrophotometer suitable for student investigations of fundamental spectrometry concepts, basic principles of optical microscopy, and some interesting phenomena unique to spectral measurements performed at the microscale. Results from several such investigations and ideas for additional applications are presented. © 2011 The American Chemical Society and Division of Chemical Education, Inc. Source

The paper develops a theoretical base for the effect of Six Sigma projects on innovation and firm performance. It has been proposed that Six Sigma projects enhance technological innovation of the firms; however, they are beneficial for firms in stable environments. Since Six Sigma programs are focused on variance reduction and efficiency, these initiatives are not very effective in dynamic environments, where the rate of technological change is dramatic. With their emphasis on variance-reduction and efficiency Six Sigma programs can be effective in enhancing incremental innovation. In addition, due to the focus of Six Sigma projects on existing customers, they may impede innovation for new customers. Accordingly, implementing Six Sigma projects in fast pace environments with high level of innovation and change may be a challenge, and may not result in the expected outcome. Building upon theories form process management and quality management the paper proposes several propositions to address the effect of Six Sigma projects on innovation and firm performance. © 2010.

Disaster Prevention and Management | Year: 2011
Purpose: The purpose of this paper is to suggest the utility of an emergency management perspective as a guide for policy makers as they respond to the challenges of global climate change. Design/methodology/approach: This analytical paper begins with a review of scientific literature in an effort to highlight the consensus about risks and vulnerabilities associated with climate change or global warming. Applying the terminology and techniques of natural disaster planning, preparedness, response, and mitigation to climate change, an emergency management perspective is articulated as a viable framework for policy development. Findings: Based on the evidence of a growing consensus in the scientific assessment of climate change, and the need for policy interventions to address the risks and vulnerabilities associated with it, the need for a unifying perspective for policymakers at all levels is apparent. An emergency management perspective is offered herein and holds the potential to provide a foundation for meeting that need. Research limitations/implications: An emergency management perspective for global climate change highlights the linkages between the challenges it poses and natural disaster preparedness in general. This may enable policy analysts to draw on the natural hazards literature and techniques as a guide for planning and policy development. Practical implications: The effort to create a consensus of approach that will enable policy makers to speak the same language, participate in the same analysis, contribute to the same dialogue, and pursue the same goals may be advanced by this discussion. Originality/value: An emergency management perspective on climate change may offer the potential for developing the least problematic model for policy makers to incorporate as they seek to make their efforts more consistent and more responsible in the face of a global challenge. © Emerald Group Publishing Limited.

Fuzzy Sets and Systems | Year: 2012
Given a locally compact separable metric space E, a perfect transformation defined on E induces a Zadeh extension, which is a transformation from the space of all upper semicontinuous fuzzy sets defined on E to itself. Here, the latter space is equipped with the hit-or-miss topology. In this setting, each upper semicontinuous fuzzy set is identified with its hypograph, a closed subset in the product space of E and [0,1]. This approach does not require the relevant fuzzy sets to hold a compact support, and it also overcomes the drawback of the traditional level-set method. Further, it is proved that the Zadeh extension with this setting is continuous in the hit-or-miss topology; and dynamical properties of Zadeh extension regarding iteration have been explored. © 2012 Elsevier B.V.

In this project funded by the Chemical Measurement & Imaging Program of the Chemistry Division, Professor Paul Flowers of the Department of Chemistry & Physics at the University of North Carolina at Pembroke is developing new devices and protocols for the chemical analysis of very small samples. This research creates new tools and methodology for microscale chemical analysis that offer advantages in analysis time, cost and sample size requirement relative to comparable existing techniques. The project employs undergraduate assistants selected from a diverse population that is 16% American Indian and 33% African American, engaging significant numbers of students in ethnic and racial groups that are presently underrepresented in the nations scientific workforce. Curricular laboratory activities directly related to the research are being developed and integrated into existing chemistry courses at the sophomore and senior levels, significantly broadening the educational impact of the project.
Spectroelectrochemistry (SEC) refers to the simultaneous application of spectroscopic and electrochemical techniques and typically involves making spectral measurements on samples undergoing electrolysis. Since the first reports of SEC in the 1960s, these techniques have become well-established tools for characterizing the redox properties of chemical species and elucidating the mechanisms of electrode processes. A more recent and growing effort is directed towards the use of SEC as the basis for quantitative chemical analyses, essentially replacing the chemical reagents used in conventional assays with an inert, nonexpendable electrode. Professor Flowersgroup has previously developed a prototype device that permits SEC analysis of sample volumes well below one microliter, roughly two-orders of magnitude lesser than any other reported device. In this project, the basic design of this prototype is being adapted to permit flow analyses of microliter and sub-microliter samples. Simple polymer casting techniques are being utilized to fabricate these flow cells, and their performance is being evaluated using voltammetry, coulometry, chronoabsorptometry and voltabsorptometry. In parallel to the device fabrication work, microscale assays that exploit SEC measurement strategies are being developed for selected compounds of biological and biomedical relevance.
