In Defense of the Land Residual Theory and the Absence of a Business Value Component for Retail Property
The temptation is strong for arguing that property values can be broken down into land, improvements, and business value, as only land and improvements are subject to property tax. As sympathetic as the authors are to this motivation, the notion of a long-run business value component for retail property is refuted and the land residual value theory reasserted, while at the same time admitting the possibility of first owner entrepreneurial or development-based value creation. It is argued that any excess property productivity will eventually become attached to the land, and last that option values are an important aspect of land values that would be affected when suggesting that the appropriate value of a given property is the cost of substituting adjacent property.
Determination of the Suitability of Arkansas River Water for Municipal, Industrial and Agricultural Use: Volume 3 Treatability Study
Volume III of the overall report for the project to determine the suitability of the Arkansas River for municipal, agricultural and industrial water supplies contains the treatability data. These data include the results of the granular activated carbon, ozonation and packed tower aeration studies. The research project was conducted under contract with the Arkansas Soil and Water Conservation Commission. Funding was provided by the Corps of Engineers, the Environmental Protection Agency, the City of Little Rock, Rockefeller Foundation and the Ozark Society. Additionally, the U.S. Geological Survey contributed financially by matching the cost of sample collection. The City of Little Rock provided funding for sampling the Little Rock site. Funding for the Lee Creek site was provided by the Environmental Protection Agency
Stimulus Threat and Exposure Context Modulate the Effect of Mere Exposure on Approach Behaviors
Mere-exposure (ME) research has found that initially neutral objects made familiar are preferred relative to novel objects. Recent work extends these preference judgments into the behavioral domain by illustrating that mere exposure prompts approachoriented behavior toward familiar stimuli. However, no investigations have examined the effect of mere exposure on approach-oriented behavior toward threatening stimuli. The current work examines this issue and also explores how exposure context interacts with stimulus threat to influence behavioral tendencies. In two experiments participants were presented with both mere-exposed and novel stimuli and approach speed was assessed. In the first experiment, when stimulus threat was presented in a homogeneous format (i.e., participants viewed exclusively neutral or threatening stimuli), ME potentiated approach behaviors for both neutral and threatening stimuli. However, in the second experiment, in which stimulus threat was presented in a heterogeneous fashion (i.e., participants viewed both neutral and threatening stimuli), mere exposure facilitated approach only for initially neutral stimuli. These results suggest that ME effects on approach behaviors are highly context sensitive and depend on both stimulus valence and exposure context. Further implications of these findings for the ME literature are discussed
Sustaining Civic Engagement: Faculty Development, Roles, and Rewards
Civic engagement of students, faculty, and staff is identified as central to the mission of
Indiana University-Purdue University Indianapolis (IUPUI). Although nearly all of the
Campus Compact Indicators of Engagement could be cited as mechanisms through
which IUPUI’s civic engagement mission is supported (Bringle and Hatcher 2004),
this article will focus on faculty roles and rewards. Following an introduction that
describes the university’s core mission and values with respect to civic engagement,
the discussion will focus on specific policies, procedures, and programs to support
faculty roles and rewards for civic engagement. A conceptual framework for faculty
development, based on experiential learning theory (Kolb 1984) is used to organize a
description of faculty development activities to promote civic engagement
Microscopic Metavehicles Powered and Steered by Embedded Optical Metasurfaces
Nanostructured dielectric metasurfaces offer unprecedented opportunities to
manipulate light by imprinting an arbitrary phase-gradient on an impinging
wavefront. This has resulted in the realization of a range of flat analogs to
classical optical components like lenses, waveplates and axicons. However, the
change in linear and angular optical momentum associated with phase
manipulation also results in previously unexploited forces acting on the
metasurface itself. Here, we show that these optomechanical effects can be
utilized to construct optical metavehicles - microscopic particles that can
travel long distances under low-power plane-wave illumination while being
steered through the polarization of the incident light. We demonstrate movement
in complex patterns, self-correcting motion, and an application as transport
vehicles for microscopic cargo, including unicellular organisms. The abundance
of possible optical metasurfaces attests to the prospect of developing a wide
variety of metavehicles with specialized functional behavior.Comment: Main Text: 16 pages, 4 figures. Supporting Information: 6 pages, 9

Microarray profiling of skeletal muscle sarcoplasmic reticulum proteins
Microarrays were developed to profile the level of proteins associated with calcium regulation in sarcoplasmic reticulum (SR) isolated from porcine Longissimus muscle. The microarrays consisted of SR preparations printed onto to glass slides and probed with monoclonal antibodies to 7 target proteins. Proteins investigated included: ryanodine receptor, (RyR), dihydropyridine receptor, (DHPR), triadin (TRI), calsequestrin (CSQ), 90 kDa junctional protein (JSR90), and fast-twitch and slow-twitch SR calcium ATPases (SERCA1 and SERCA2). Signal from a fluorescentlylabeled detection antibody was measured and quantitated using a slide reader. The microarray developed was also employed to profile Longissimus muscle SR proteins from halothane genotyped animals. Significant (P\u3c0.05) reductions in levels of several proteins were found including: RyR, CSQ, TRI, DHPR and SERCA2 in SR samples from halothane positive animals. The results illustrate the potential of microarrays as a tool for profiling SR proteins and aiding investigations of calcium regulation
