Stabilization Of Polystyrene By Friedel-Crafts Chemistry: Effect Of Position Of Alcohol And The Catalyst, Jin Zhu, Michael A. Mckinney, Charles Wilkie

Chemistry Faculty Research and Publications

Polystyrene has been copolymerized with 4-vinylbenzyl alcohol, 4-(2-hydroxyethyl)styrene, and 4-(3-hydroxypropyl)styrene and it has been shown that thermal cross-linking of these copolymers is dependent upon the alcohol content. When the alcohol content is low, no thermal cross-linking is observed. When various phosphate esters are present as catalysts with these low alcohol content copolymers, cross-linking is observed at temperatures of about 250°C but not at lower temperatures. Cross-linking enhances the thermal stability of the copolymers. Studies of the thermal stability of the copolymers and their blends with the catalysts have been performed using thermogravimetric analysis and thermogravimetric analysis coupled to Fourier transform …

Validity Of The Previous Day Physical Activity Recall (Pdpar) In Fifth-Grade Children, Stewart G. Trost, Dianne S. Ward, Ben Mcgraw, Russell R. Pate

Faculty Publications

This study evaluated the validity of the Previous Day Physical Activity Recall (PDPAR) self-report instrument in quantifying after-school physical activity behavior in fifth-grade children. Thirty-eight fifth-grade students (mean age, 10.8 ± 0.1; 52.6%; female; 26.3% African American) from two urban elementary schools completed the PDPAR after wearing a CSA WAM 7164 accelerometer for a day. The mean within-subject correlation between self-reported MET level and total counts for each 30-min block was 0.57 (95% C.I., 0.51-0.62). Self-reported mean MET level during the after-school period and the number of 30-min blocks with activity rated at > 6 METs were significantly correlated with the …

1999 Safety Belt Usage Survey In Kentucky, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objective of this study was to establish 1999 safety belt and child safety seat usage rates in Kentucky. The 1999 survey continues to document the results after enactment of a statewide mandatory safety belt law in 1994. Data were collected at 200 sites spread across Kentucky. Data from the individual sites were combined into a statewide percentage considering function classification, geographic region, and vehicle miles traveled.

The data show that the usage rate increased in 1999 after a few years where the rate had remained at a stable level below the highest value which occurred in 1994 immediately after …

An Investigation Of Price Discovery In Informationally-Linked Markets: Equity Trading In Malaysia And Singapore, David K. Ding, Frederick H. Harris, Sie Ting Lau, Thomas H. Mclnish

Research Collection Lee Kong Chian School Of Business

Using transactions data for the Kuala Lumpur Stock Exchange and the Stock Exchange of Singapore (SES) for a major Malaysian conglomerate, Sime Darby Berhad, and intraday exchange rate data, we investigate whether and to what extent each exchange contributes to price discovery. Results indicate that the price series are cointegrated. The raw data appear to indicate the presence of arbitrage opportunities, but none exist after taking exchange rate changes into account. Using the common long-memory factors of Gonzalo and Granger (1995, Journal of Business and Economic Statistics 13, 1-9), we show that while the majority of the price discovery (approximately …

Multivariate Density Forecast Evaluation And Calibration In Financial Risk Management: High-Frequency Returns On Foreign Exchange, Francis X. Diebold, Jinyong Hahn, Anthony S. Tay

Research Collection School Of Economics

We provide a framework for evaluating and improving multivariate density forecasts. Among other things, the multivariate framework lets us evaluate the adequacy of density forecasts involving cross-variable interactions, such as time-varying conditional correlations. We also provide conditions under which a technique of density forecast calibration can be used to improve deficient density forecasts, and we show how the calibration method can be used to generate good density forecasts from econometric models, even when the conditional density is unknown. Finally, motivated by recent advances in financial risk management, we provide a detailed application to multivariate high-frequency exchange rate density forecasts. © …

Ethnic Variability In The Treatment Of Pain, Rafael A. Ortega, Benjamin A. Youdelman, Richard C. Havel

Department of Surgery Faculty Papers

Ethnicity has been shown to be an important determinant of behavior during illness, particularly when a painful condition is present. Studies have shown that pain may be undertreated among different ethnic groups of patients. Whereas individual variations in the reaction to pain occur, available data do not support racial and/or ethnic differences in the perception of pain, leaving no justification for this discrepancy in treatment. Regardless of ethnicity, inadequate treatment of pain has been known for some time and has been referred to in recent literature as "oligoanalgesia." Lack of understanding of different ethnic and cultural groups can lead to …

Seeing More Than We Can Know: Visual Attention And Category Activation, Cn Macrae, Gv Bodenhausen, Ab Milne, G Calvini

School of Psychology

Extending existing work on the conditional automaticity of category activation, the present research investigated the extent to which category activation is moderated by the resolution of visual attention. As visual attention gates access to material in semantic memory, so too should it regulate the activation of social categories when triggering verbal labels are encountered. Accordingly, only when triggering stimuli fall within the spotlight of attention did we expect category activation to occur. The results of two studies supported this prediction. We consider the implications of our findings for recent treatments of category automaticity.

A Longitudinal Examination Of The Consequences Of Sexual Victimization For Rural Young Adult Women, Janine Zweig, Lisa J. Crockett, Aline Sayer, Judith Vicary

Department of Psychology: Faculty Publications

This longitudinal study examined the consequences of sexual victimization in a sample of 237 young adult women from a rural community. Of the total sample, 71 (30%) reported experiencing some type of unwanted sex. Multiple regression was used to examine the effects on psychosocial adjustment of unwanted sex that occurred through nonviolent coercion and violent coercion, respectively, controlling for prior psychological adjustment. Results indicated that women who reported physically violent sexual coercion exhibited poorer psychological and social/relational adjustment than either nonvictimized women or women who had experienced nonviolent forms of sexual coercion. Additionally, nonviolent sexual coercion was associated with higher …

Whose Who? The Case For A Kantian Right Of Publicity, Alice Haemmerli

Duke Law Journal

Rapidly developing technological opportunities for unauthorized uses of identity-from "virtual kidnapping" to digitalcasting-coincide with growing demand for a preemptive federal right of publicity that can replace the existing welter of inconsistent state laws. Progress is impeded, however, by intractable doctrinal confusion and academic hostility to the right as allegedly inimical to society's cultural need to manipulate celebrity images. Because the right of publicity is traditionally based on Lockean labor theory and analogized to intellectual property in created works, it is vulnerable to such attacks; to date, no serious attempt has been made to elaborate an alternative philosophical justification that can …

Azidothymidine And Interferon-Α Induce Apoptosis In Herpesvirus-Associated Lymphomas, Richard K. Lee, Jian-Ping Cai, Vadim Deyev, Parkash Gill, Lisa Cabral, Charles Wood, Ram Agarwal, Wenle Xia, Lawrence Boise, Eckhard Podack, William Harrington Jr.

Nebraska Center for Virology: Faculty Publications

Lymphoproliferative diseases that occur in immunocompromised patients are frequently associated with herpesviruses. These patients often fare poorly after treatment with conventional chemotherapy. We reported previously that patients with AIDS-related Burkitt’s lymphoma (BL) responded to parenteral azidothymidine (AZT) and IFN-α. We found that EBV-positive lymphoma cells derived from these patients cultured with AZT express CD95 and undergo apoptosis. AZT-mediated apoptosis was caspase dependent and occurred despite Fas receptor blockade. In contrast, EBV-negative lymphomas were resistant to AZT-induced apoptosis, as were EBV-positive lymphomas that expressed high levels of bcl-2. Primary effusion lymphoma (PEL) cell lines infected with human herpesvirus type 8 required …

Expression Of Relationship In Life, Hoyeon Chung

Theses

This paper discusses a series of five sculptures that were made during my two years of graduate school at Rochester Institute of Technology. During that period, I realized and contemplated my existence. I spent much of my first year thinking about my emotions. The inspirations around me were getting more broad starting from different the interactions in all elements of my life. This idea also might be universal. Even though all lives are different, there are similar characteristics that most people possess. People are living within boundaries. The boundaries can consist of several elements, such as family, friends, environment and …

A La Conquista, Carlos Ruiz-Valarino

Theses

This thesis paper is an integral and complementary part of my thesis exhibition "A la conquista . . .” Its purpose is to enhance my audience's understanding of the interests and vicissitudes that have motivated me to undertake such a challenging task. This project has its origin in an earlier autobiographical photographic project. Through it I developed an interest in visually questioning aspects related to my past and present: How did I become the individual I am? And what aspects of my experience define my identity? My parents are of different nationalities, I was born in Puerto Rico, and then …

Post–Green Revolution Trends In Yield Potential Of Temperate Maize In The North-Central United States, D. N. Duvick, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

This paper addresses the question of whether there has been an increase in yield potential of maize (Zea mays L.) hybrids released in the north-central United States since the advent of the “Green Revolution” that began in the late 1960s. Because there are few published data about hybrid growth rates and yield-determining plant traits when grown at yield potential levels, we attempt to address this issue indirectly by evaluation of maize breeding efforts, changes in plant traits of commercial hybrids, and by comparison of statewide average yield trends and yield trends in sanctioned yield contests. On the basis of …

Kentucky Transportation Center Research Report

This report presents the seismic evaluation of the US41 Northbound bridge over the Ohio River connecting Evansville, Indiana and Henderson, Kentucky. The main bridge is a four-span cantilever through-truss type. The approach bridge has 8 spans on the Evansville, IN side and 35 spans on the Henderson, KY side. Although this bridge has not yet been subjected to a moderate or major earthquake, it is situated within the influence of the New Madrid and Wabash Valley Seismic Zones.

The seismic evaluation program consisted of field testing and seismic response analysis. The modal properties of the main bridge were determined through …

Investigation Of Image Feature Extraction By A Genetic Algorithm, Steven P. Brumby, James P. Theiler, Simon J. Perkins, Neal R. Harvey, John J. Szymanski, Jeffrey J. Bloch, Melanie Mitchell

Computer Science Faculty Publications and Presentations

We describe the implementation and performance of a genetic algorithm which generates image feature extraction algorithms for remote sensing applications. We describe our basis set of primitive image operators and present our chromosomal representation of a complete algorithm. Our initial application has been geospatial feature extraction using publicly available multi-spectral aerial-photography data sets. We present the preliminary results of our analysis of the efficiency of the classic genetic operations of crossover and mutation for our application, and discuss our choice of evolutionary control parameters. We exhibit some of our evolved algorithms, and discuss possible avenues for future progress.

Choice Or Commonality: Welfare And Schooling After The End Of Welfare As We Knew It, Martha Minow

Duke Law Journal

Reflecting market rhetoric but also potentially advancing spiritual and religious values, school voucher plans dominate current debates on education reform. These voucher plans would enable parents to use public dollars to select private schools, including parochial ones, for their children. Moreover, the recent federal welfare reform includes the "charitable choice" provision, which enables states to issue vouchers to individuals who can redeem them for services and aid from private, including religious, entities. In this Article, Professor Minow predicts that constitutional challenges to these plans under the religion clauses are likely to result in judicial approval of school vouchers and judicial …

An Elliptic Partial Differential Equation With A Symmetrical Almost Periodic Term, Gregory S. Spradlin

Publications

In [STT], a Hamiltonian system of the form (1.0)− u′′+ u= h (t)∇ F (u) was studied, where h is an almost periodic (defined in a moment) function, and F: RN→ R a “superquadratic” potential. That is, F (q) behaves like q to a power greater than 2, with F (q)/| q| 2→ 0 as| q|→ 0 and F (q)/| q| 2→∞ as| q|→∞. For example, F (q)=| q| p− 1q with p> 1 would qualify. The authors found that (1.0) must have a nonzero solution homoclinic to zero. Since this result, many papers (see [CMN],[R1], and [ACM], for example) …
