Productivity in Higher Education/ Kevin Stange, Kevin Strange, Caroline M. Hoxby.
No full textIn English.How do the benefits of higher education compare with its costs, and how does this comparison vary across individuals and institutions? These questions are fundamental to quantifying the productivity of the education sector. The studies in Productivity in Higher Education use rich and novel administrative data, modern econometric methods, and careful institutional analysis to explore productivity issues. The authors examine the returns to undergraduate education, differences in costs by major, the productivity of for-profit schools, the productivity of various types of faculty and of outcomes, the effects of online education on the higher education market, and the ways in which the productivity of different institutions responds to market forces. The analyses recognize five key challenges to assessing productivity in higher education: the potential for multiple student outcomes in terms of skills, earnings, invention, and employment; the fact that colleges and universities are "multiproduct" firms that conduct varied activities across many domains; the fact that students select which school to attend based in part on their aptitude; the difficulty of attributing outcomes to individual institutions when students attend more than one; and the possibility that some of the benefits of higher education may arise from the system as a whole rather than from a single institution. The findings and the approaches illustrated can facilitate decision-making processes in higher education.Hoxby, Caroline M. / Stange, Kevin -- Staiger, Douglas -- Hoxby, Caroline M. -- Minaya, Veronica / Scott-Clayton, Judith -- Riehl, Evan / Saavedra, Juan E. / Urquiola, Miguel -- Altonji, Joseph G. / Zimmerman, Seth D. -- Courant, Paul N. / Turner, Sarah -- Vlieger, Pieter De / Jacob, Brian / Stange, Kevin -- Deming, David J. / Lovenheim, Michael / Patterson, Richard -- Carrell, Scott E. / Kurlaender, Michal -- Frontmatter -- Contents -- Acknowledgments -- Introduction / 1.

Intrinsic Verification and a Heat Conduction Database
No full textIn this paper several unique concepts in transient heat conduction are discussed, including intrinsic verification, time partitioning, and a database of solutions organized with a numbering system. The database and numbering system have been developed to address the following problem: existing solutions in books and traditional publications are not truly organized, and consequently they are not readily accessible. The database that we have developed contains added material such as algorithms, consistent statements of the number of required terms, and verified computer programs for evaluating eigenvalues and solutions. The purpose of the database, called the Exact Analytical Conduction Toolbox, is to provide improved access to precise numerical values from verified solutions for application to engineering problems of current interest. Heat conduction is an appropriate discipline in which to develop and demonstrate these concepts because it is a mature field with a large number of existing analytical solutions. It is anticipated that these concepts can also be applied to diverse fields in engineering and science. Several examples are given of exact analytical solutions that are available in the database, some not previously published. One application for this type of exact analytical solution is for measurement of thermal properties
The Effectiveness of 3-D Compared to 2-D Signage on Recycling Behaviour
No full textUsing 3-D objects as examples, rather than 2-D icons on signs, to help people learn recycling categories has shown mixed results in observational studies, so an online experimental study was conducted to attempt to clarify the findings. The main hypothesis was that participants would perform faster and more accurately if they learned the recycling categories through images of 3-D objects rather than by 2-D icons. Furthermore, several exploratory hypotheses were suggested: Participants given both types of signage—3-D + 2-D—would perform better than the 3-D and 2-D conditions on their own, and subjective workload and user engagement would predict differences in performance between conditions. An ANOVA found no differences between any of the three conditions in terms of accuracy of sorting performance, subjective workload, or user engagement. However, the 3-D + 2-D condition demonstrated a significant, small-to-medium sized increase in sorting speed when compared to the other two conditions, suggesting that combined 3-D + 2-D signage speeds up decision making without negatively impacting accuracy. One possible explanation is that redundancy of information in the combined condition reduced uncertainty and led to increased speed. However, replication of this result is required because of some limitations inherent to the current study
A panel discussion on the UAW Local 602 Fisher Body Oral History Project at the 33rd North American Labor History Conference
No full textJohn P. Beck, Michigan State University Professor of Human Resource and Labor Relations, kicks off a panel discussion of the UAW Local 602 Fisher Body Oral History project, during a session at the North American Labor History Conference at Wayne State University in Detroit, MI. Beck introduces the panelists and talks about the scholarly value of the collection. Doug Rademacher, former Local 602 Preident, describes his involvement in the project and how interviewees were identified and recruited and Marilyn Coulter, a former Fisher Body production worker, explains how she came to the project and how interviews were conducted. John Shaw, from the Michigan State University Libraries, discusses how the material came to the G. Robert Vincent Voice Library, how it was processed and cataloged and the construction of the Lansing Auto Town Gallery website. Kevin Beard, also from the MSU Libraries, plays excerpts from some of the interviews and discusses the experiences of African-Americans and women, as portrayed by interviewees. Nancy Darga, Director of the Motorcities National Heritage Area, discusses that organization's involvement in the project and their interest in preserving Michigan\u2019s rich manufacturing heritage
Applications in Education for a Heat Conduction Database
No full textApplied computer solutions for conductive heat transfer are a
critical component in any modern undergraduate heat transfer
course. This need has been addressed in many ways through
various textbook exercises and software packages. The present
work involves a catalog of analytical solutions organized with a
numbering system that describes the boundary conditions and
initial conditions for each problem. The solutions are preprogrammed
and accessible via a free web site called the Exact
Analytical Conduction Toolbox, or EXACT. Students can
access these solutions for use in homework and project work.
In this paper examples of several types of student exercises are
given, including a re-creation of the Heisler charts and a two
dimensional steady-state example. Additionally, an account is
given of classroom use of these tools in a graduate heat transfer
course, outlining the education advantages of the EXACT web
page. The concept of intrinsic verification is also discussed,
focusing on the applicability of this concept to enhancing
insight among undergraduate students. General support is also
expressed for the need of analytical solutions to heat transfer
and diffusion problems in an undergraduate setting
