Economic And Social Impacts Of Wildfires And Invasive Plants In American Deserts: Lessons From The Great Basin, Mark Brunson, John Tanaka
Economic And Social Impacts Of Wildfires And Invasive Plants In American Deserts: Lessons From The Great Basin, Mark Brunson, John Tanaka
John A Tanaka
Research on the impacts of wildfire and invasive plants in rangelands has focused on biophysical rather than human dimensions of these environmental processes. We offer a synthetic perspective on economic and social aspects of wildfire and invasive plants in American deserts, focusing on the Great Basin because greater research attention has been given to the effects of cheatgrass expansion than to other desert wildfire/invasion cycles. We focus first on impacts at the level of the individual decision-maker, then on impacts experienced at the human community or larger socio-political scales. Economic impacts of wildfire differ from those of invasive grasses because …

Economic Freedom And Fiscal Performance: A Regression Analysis Of Indices Of Economic Freedom On Per Capita Gdp, Jason Ockey
Economic Freedom And Fiscal Performance: A Regression Analysis Of Indices Of Economic Freedom On Per Capita Gdp, Jason Ockey
Jason R Ockey
This paper explores whether different forms of economic freedom drive fiscal performance. We also seek to determine which specific measurements of economic freedom have the most statistically significant impacts. Though the results of our analysis show that economic freedom does impact levels of per capita GDP, the interpretation of these results is more complicated. Because some indices of economic freedom have negative effects on per capita GDP or are statistically insignificant, it is important to note that simply generally increasing a country’s overall level of economic freedom will not necessarily spur economic growth or increase fiscal performance. This paper does …
Economic Approaches To Global Regulation: Expanding The International Law And Economics Paradigm, Dan Danielsen
Economic Approaches To Global Regulation: Expanding The International Law And Economics Paradigm, Dan Danielsen
Dan Danielsen
The recent economic crisis has demonstrated with startling clarity the importance of developing a more robust framework for assessing the effects of national rules on global welfare. For more than fifty years, law and economics scholars have examined the effects of domestic legal rules on economic activity and general welfare in the United States. More recently, international law scholars have begun to use economic methods to analyze the international legal order. In this article I survey this evolving body of “international law and economics scholarship” with a view to articulating its principle methodological innovations as well as assessing its contributions …
Local Rules And A Global Economy: An Economic Policy Perspective, Dan Danielsen
Local Rules And A Global Economy: An Economic Policy Perspective, Dan Danielsen
Dan Danielsen
This article explores the growing significance and theoretical implications of ‘local rules’—such as Chinese labour standards, US financial regulation and Swiss bank secrecy rules—in the global economy. In particular, the argument developed is that Ronald Coase’s framework for analysing the effects of legal rules on economic welfare can help to reveal important weaknesses in current international legal approaches to analysing the transnational impact of local rules as well as contribute to a ‘global economic policy perspective’ better attuned to problems of power in the global regulatory order. Such a perspective will help us to see the effects of power differences …
Determining Magnetic Nanoparticle Size Distributions From Thermomagnetic Measurements, R. Dipietro, H. Johnson, S. Bennett, T. Nummy, L. Lewis, D. Heiman
Determining Magnetic Nanoparticle Size Distributions From Thermomagnetic Measurements, R. Dipietro, H. Johnson, S. Bennett, T. Nummy, L. Lewis, D. Heiman
Laura H. Lewis
Thermomagnetic measurements are used to obtain the size distribution and anisotropy of magnetic nanoparticles. An analytical transformation method is described which utilizes temperature-dependent zero-field cooling (ZFC) magnetization data to provide a quantitative measurement of the average diameter and relative abundance of superparamagnetic nanoparticles. Applying this method to self-assembled MnAs nanoparticles in MnAs-GaAs composite films reveals a log-normal size distribution and reduced anisotropy for nanoparticles compared to bulk materials. This analytical technique holds promise for rapid assessment of the size distribution of an ensemble of superparamagnetic nanoparticles.
Magnetic Signature Of Symmetry Reduction In Epitaxial La₀.₆₇Sr₀.₃₃Mno₃ Films, Radhika Barua, L. Lewis, D. Heiman
Magnetic Signature Of Symmetry Reduction In Epitaxial La₀.₆₇Sr₀.₃₃Mno₃ Films, Radhika Barua, L. Lewis, D. Heiman
Laura H. Lewis
The magnetic properties of epitaxially grown La0.67Sr0.33MnO3 perovskite thin films were investigated to elucidate an unexpected broken symmetry between orthogonal [100] and [010] inplane directions, resulting from the magnetostructural coupling between the film and the cubic SrTiO3 (001) substrate. The films were synthesized by molecular beam epitaxy with either complete or zero A-site cation disorder. Magnetization measured in [100] and [010] directions shows differences that signal a reduction of the in-plane cubic symmetry only for T < 290 K. The magnetization asymmetry is more robust in the film with complete A-site disorder. These results are attributed to a dominant Mn3+ character …
Universal Properties Of Linear Magnetoresistance In Strongly Disordered Mnas-Gaas Composite Semiconductors, H. Johnson, S. Bennett, R. Barua, L. Lewis, D. Heiman
Universal Properties Of Linear Magnetoresistance In Strongly Disordered Mnas-Gaas Composite Semiconductors, H. Johnson, S. Bennett, R. Barua, L. Lewis, D. Heiman
Donald Heiman
Linear magnetoresistance (LMR) occurs in semiconductors as a consequence of strong electrical disorder and is characterized by nonsaturating magnetoresistance that is proportional to the applied magnetic field. By investigating a disordered MnAs-GaAs composite material, it is found that the magnitude of the LMR is numerically equal to the carrier mobility over a wide range and is independent of carrier density. This behavior is complementary to the Hall effect that is independent of the mobility and dependent on the carrier density. Moreover, the LMR appears to be insensitive to the details of the disorder and points to a universal explanation of …
Nonparametric Copula Density Estimation In Sensor Networks, Leming Qu, Hao Chen, Yicheng Tu
Nonparametric Copula Density Estimation In Sensor Networks, Leming Qu, Hao Chen, Yicheng Tu
Leming Qu
Statistical and machine learning is a fundamental task in sensor networks. Real world data almost always exhibit dependence among different features. Copulas are full measures of statistical dependence among random variables. Estimating the underlying copula density function from distributed data is an important aspect of statistical learning in sensor networks. With limited communication capacities or privacy concerns, centralization of the data is often impossible. By only collecting the ranks of the data observed by different sensors, we estimate and evaluate the copula density on an equally spaced grid after binning the standardized ranks at the fusion center. Without assuming any …

Designing To Learn About Complex Systems, Cindy Hmelo, Doug Holton, Janet Kolodner
Designing To Learn About Complex Systems, Cindy Hmelo, Doug Holton, Janet Kolodner
Douglas L Holton
Complex systems are commonly found in natural and physical science. Understanding such systems is often difficult because they may be viewed from multiple perspectives and their analysis may conflict with or extend beyond the range of everyday experience. There are many complex structural, behavioral, and functional relations to understand as well. Design activities, which allow explorations of how systems work, can be an excellent way to help children acquire a deeper, more systemic understanding of such complex domains. We report on a design experiment in which 6th grade children learned about the human respiratory system by designing artificial lungs and …

R. Eric Landrum
The association of total study time, number of events, time per event ratio, study strategies, and course grades across the semester were examined by linking students' study logs to course performance. There were 37 upper-division and 109 lower-division participants. Students earning As and Bs studied more frequently at the end of the semester but for shorter periods of time than students earning lower grades. Results are discussed in terms of providing college students and faculty with recommendations about learning strategies and time spent studying.
Sensitivity Of Implicit Memory To Input Processing And The Zeigarnik Effect, R. Landrum
Sensitivity Of Implicit Memory To Input Processing And The Zeigarnik Effect, R. Landrum
R. Eric Landrum
Implicit memory is evidenced when a subject benefits from a previous experience without making a conscious effort to recollect that prior experience. In the present study, I examined the sensitivity of implicit memory to two variables: type of input processing and the temporal placement of the implicit memory test. Results indicated that although implicit memory occurred in all conditions, its magnitude was sensitive to both variables. The results are discussed in terms of the underlying nature of implicit memory, including the role of transfer-appropriate processing.

Satisfaction With College By Traditional And Nontraditional College Students, R. Landrum, J Et'aime Hood, Jerry Mcadams
R. Eric Landrum
University students (N=433) were surveyed about their satisfaction with a number of campus services and opportunities. Comparisons between traditional (up to 24 years old) and nontraditional (25 years and up) students indicated the latter valued learning and school opportunities more and appreciated the efforts of their professors in interacting with them and communicating information. A number of similarities were noted. University administrations need to be aware of the important differences between such groups to be able to enhance students' safisfaction.

Departmental Search Committees And The Evaluation Of Faculty Applicants, R. Landrum, Michael Clump
R. Eric Landrum
We surveyed directors of departmental search committees (N = 89) to ascertain which criteria have the most value in the faculty applicant selection process. Respondents used several methodological techniques, including rank order, agreement, and importance scale questions. Results indicated that match or fit with department is the most important criterion in applicant selection, followed by research and teaching experience. Important differences emerged in the evaluation of job applicants depending on the type of institution (public vs. private) or type of department (undergraduate-only vs. undergraduate + graduate program).

Scaling Issues In Faculty Evaluations, R. Landrum
R. Eric Landrum
148 students were asked to evaluate particular survey questions with scales that varied in number of scale points, type of labeling and labeling of achors only vs all scale points. No significant difference was found between variations on 4- and 5-point scales, so these data were collapsed. Analysis indicated that students generated scale-point exemplars significantly better for 4-point scales (96.7%) than for 5-point (87.8%) and 10-point (79.3%) scales. These results are discussed with respect to the administration of student evaluations and the care required in selecting a scale type and interpreting the subesequent outcomes.

This type of course is becoming popular, with 34.2% of reporting departments offering such a course. Respondents rated 33 undergraduate education issues with respect to importance. We discuss these results in the context of increasing popularity of the psychology major and the course-based method of communicating academic and career advising information to students.
Using Computers To Support Children As Authors: An Examination Of Three Cases, Lisa Kervin, Jessica Mantei
Using Computers To Support Children As Authors: An Examination Of Three Cases, Lisa Kervin, Jessica Mantei
Jessica Mantei
The changing nature of literacy is well documented within the literature, challenging educators to examine their pedagogies in light of the needs of learners in the current climate. The development and creation of non‐linear texts within primary classrooms is of current interest as they reflect the types of texts accessed and created by users of technology and afford children opportunities to make connections between their in and out of school literacy experiences. The authors observed children over extended periods as they collaborated with teachers and peers to author non‐linear texts for a range of purposes. Three case studies will be …
