Numeracy: Open-Access Publishing To Reduce The Cost Of Scholarly Journals, Todd A. Chavez Dec 2009

Numeracy: Open-Access Publishing To Reduce The Cost Of Scholarly Journals, Todd A. Chavez

Numeracy

Each fiscal year, as academic librarians throughout the United States prepare materials budgets, a national “groan” ensues. Regardless of their format (i.e. print or digital), serial subscription costs are escalating, in the process impacting the role of the library in advancing scholarly communication . This paper examines some of the economic issues concerning open-access (OA) journal publishing. The importance of quantitative literacy is suggested for librarians and academics seeking a better understanding of alternatives to traditional journal subscription models and to anyone considering ventures into OA publishing. Quantitative literacy is essential for managing alternatives to the rising cost of scholarly …

Electrical Impedance Imaging Of Corrosion On A Partially Accessible 2-Dimensional Region, Court Hoang, Katherine Osenbach Dec 2009

Electrical Impedance Imaging Of Corrosion On A Partially Accessible 2-Dimensional Region, Court Hoang, Katherine Osenbach

Mathematical Sciences Technical Reports (MSTR)

In this paper we examine the inverse problem of determining the amount of corrosion on an inaccessible surface of a two-dimensional region. Using numerical methods, we develop an algorithm for approximating corrosion profile using measurements of electrical potential along the accessible portion of the region. We also evaluate the effect of error on the problem, address the issue of ill-posedness, and develop a method of regularization to correct for this error. An examination of solution uniqueness is also presented.

Paradoxical Perceptions Of Problems Associated With Unconventional Natural Gas Development, Gene L. Theodori Dec 2009

Paradoxical Perceptions Of Problems Associated With Unconventional Natural Gas Development, Gene L. Theodori

Journal of Rural Social Sciences

Data collected in a general population survey from a random sample of individuals in two counties located in the Barnett Shale region of Texas were used to empirically explore potentially problematic issues associated with unconventional natural gas development. Moderate support was found for the hypothesis that individuals residing in places with diverse levels of energy development exhibit dissimilar perceptions of potentially problematic issues. The results indicate residents of the county where the natural gas industry was more mature (Wise County) were significantly more likely than residents of the county where the natural gas industry was less established (Johnson County) to …

Environmental Strategies And Their Motives And Results In Slovenian Business Practice, Tomaž Čater, Janez Prašnikar, Barbara Čater Dec 2009

Environmental Strategies And Their Motives And Results In Slovenian Business Practice, Tomaž Čater, Janez Prašnikar, Barbara Čater

Economic and Business Review

The results of a survey on 153 Slovenian manufacturing companies show that companies implement environmental strategies primarily as a refl ection of the commitment of their top management, followed by public concern, regulatory forces and expected competitive advantage. They report a relatively high level of implementation of the corporate environmental strategy while, among functional strategies, environmental issues are most commonly included in the production and marketing strategies, followed by purchasing and personnel strategies. Large companies develop and execute environmental strategies to a greater extent than small companies. The results also reveal a positive but very weak relationship between environmental strategies …

Cutting As A Continuous Business Process, Peter Trkman, Jure Erjavec, Miro Gradišar Dec 2009

Cutting As A Continuous Business Process, Peter Trkman, Jure Erjavec, Miro Gradišar

Economic and Business Review

A review of state-of-the-art methods for cutting stock problem optimisation shows that the current methods lead to near-optimum results for the instantaneous optimisation of trim loss. Further optimisation of this activity would not bring a considerable improvement. Therefore, the paper treats cutting stock as a continuous business process and not as an isolated activity. An exact method for a general one-dimensional cutting stock problem is presented and tested. The method is mainly suitable for smaller orders. It is then applied to continuous cutting and used to develop a method for assessing cutting costs in consecutive time periods. The modified method …

How To Cope With Distance In The Future?, Guy Fournier Dec 2009

How To Cope With Distance In The Future?, Guy Fournier

Economic and Business Review

Mobility is essential to life, human needs, and economic development. Diminishing oil reserves, a growing dependency on oil and global warming will all strongly impact on mobility. However, innovative solutions exist. To keep mobility affordable it is likely that fossil-oil-based mobility will not be substituted by just one technology. Secondand third-generation biofuels and electric vehicles are some of the best ways to be energy and CO2 efficient in a well-to-wheel view. In contrast, fuel cells do not seem to be an alternative. Original equipment manufacturers (OEM) and suppliers will be firmly impacted by this evolution. The fastest and most innovative …

Calibration Of Hdm-4 For Use In Pavement Management Systems (Pms), Nurdin Mushule

Tanzania Journal of Engineering and Technology (TJET)

One of major problems of road management in developing countries is the lack of decision making tools for preparing road maintenance programmes. This results in poor resource allocation and poor utilisation of existing assets. Pavement management systems (PMS) have been developed around the world in order to assist with the pavement management process in a co-ordinated and systematic manner. Some developed countries have derived pavement performance models that are suited to local conditions by setting up long term pavement performance studies. Conversely, most developing countries do not have the resources required to set up similar large-scale field experiments. However, validation …

Managing A Creative Practice, Julie C. Barrett Dec 2009

Managing A Creative Practice, Julie C. Barrett

Critical and Creative Thinking Capstones Collection

Myths and assumptions about creativity often lead us to believe that creativity is innate. Researchers find though, that we develop creative skills like any other ability, through opportunity, encouragement and practice. They also believe that most people fail to reach their creative potential, not because of lack of ability, but lack of opportunity. In this paper, I studied how creativity functions (specifically in terms of my own painting practice) and how it can be applied more flexibly. Certain factors, such as access to strong mentors, freedom to experiment, and readily available resources, help potentially exceptional minds find the passion to …
