The Hemp Controversy: Can Industrial Hemp Save Kentucky?, Susan David Demaine

Articles by Maurer Faculty

In the wake of litigation over the responsibility of tobacco companies for harm caused by cigarettes and in the face of increased public hostility toward smoking, Kentucky's tobacco farmers are apprehensive about the future. While not all growers depend entirely on tobacco for their income, the potential shrinking of the tobacco market will have serious ramifications throughout the state. Some farmers are turning to organic vegetable farming, or to com and soybeans as alternative crops, but the potential of industrial hemp as an option remains uncertain. Touted by many as the answer to the tobacco farmer's quandary, industrial hemp remains …

Edward Alsworth Ross In Chicago, Michael R. Hill

Department of Sociology: Faculty Publications

THE NAMES “Edward A. Ross” and “Chicago sociology” are not usually linked today in sociological accounts of the discipline, but the connections are nonetheless tangible. Ross’s work at Stanford, Nebraska, and Wisconsin is, perhaps, better known (Hertzler 1951; Hill forthcoming; Hinkle 1980; Howard 1988; Keith 1988; Weinberg 1972) and has overshadowed Ross’ ties to Chicago. The “symposium” presented below in this issue of SOCIOLOGICAL ORIGINS celebrates Ross’ place in Chicago sociology.

The record shows that Ross taught briefly in 1896 as a Visiting Professor of Sociology at the University of Chicago, lectured informally to the University of Chicago Sociological Club, …

What Is Learned About Nontarget Items In Simple Visual Search?, John H. Flowers, Karen L. Smith

Department of Psychology: Faculty Publications

Human sensitivity to correlational structure between nontargets and likelihood of target presence in a visual letter-search task were studied in two experiments. In each of these experiments, the performance of subjects for whom the nontarget information was altered in the final trial block was compared with the performance of subjects for whom the nontarget information did not change. When stimulus strings were presented individually on a computer screen and subjects were required to make a yes–no decision about target presence (Experiment 1), the change in nontarget structure resulted in increased reaction times for target-absent trials. When subjects searched simultaneously for …

The Delimitation Of Outer Space Revisited The Role Of National Space Laws In The Delimitation Issue, Frans G. Von Der Dunk

Space, Cyber, and Telecommunications Law Program: Faculty Publications

Recently, the issue of the delimitation and definition of outer space has been put back on the agenda of the Legal Subcommittee of UNCOPUOS. This issue has of course many complex features. It effectively revisits the fundamental but rather theoretical debate between proponents of 'spatialism' and adherents to 'functionalism' when it comes to defining the essence of international space law. It reflects on a measure of absence of political will to establish any rigid delimitation and definition ahead of technical or other developments which may tend to ignore such legal borderlines. Moreover, even amongst those agreeing on the need to …

Principles And Application Of Credibility Theory, Vincent Goulet

Journal of Actuarial Practice (1993–2006)

We review the history of the practical development of credibility theory. Emphasis is placed on the two main approaches to credibility theory: limited fluctuation credibility and greatest accuracy credibility. We explain when each approach should and should not be used. The presentation of greatest accuracy credibility theory starts with a review of (exact) Bayesian credibility and then moves to the Buhlmann-Straub model. Estimators of the structure parameters are discussed. Examples are presented to illustrate the concepts. Finally, the hierarchical credibility and crossed classification credibility models are presented.

Actuarial Techniques In Risk Pricing And Cash Flow Analysis For U.K. Bank Loans, Philip Booth, Duncan E.P. Walsh

Journal of Actuarial Practice (1993–2006)

A cash flow model is developed to set the price for a loan to a borrower with known risks. Similarities are noted between this model and those used for profit testing in life insurance. We emphasize aspects that reasonably can be treated in several ways and also indicate where the cash flow model differs from the pricing methods usually employed in bank lending. The sensitivity of interest rates to various parameters of the model such as the length of loan and the expected default rate is examined. Also, we examine how features of loans, including cash back and early repayments, …

A Frailty Model For Projection Of Human Mortality Improvements, Shaun S. Wang, Robert L. Brown

Journal of Actuarial Practice (1993–2006)

Based on the everyday observations that individual human beings vary significantly in their capacity to combat death, we adopt a so-called frailty model of human mortality. This frailty model assumes that each individual in a given population is endowed with his or her own frailty index, r, which remains constant for life. In addition, we assume that the individual's force of mortality (hazard rate function) at age x, Ux(r), satisfies Ux(r) = rUx where Ux is the population's base force of mortality at age x. Given the probability distribution of the frailty index among the newborns in the population, an …

Controlled Hybridization Technique For Switchgrass, Juan M. Martinez-Reyna, Kenneth P. Vogel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Controlled hybridizations of plants are necessary for genetic studies, including those that use molecular markers. A hybridization technique for grass species such as switchgrass, Panicum virgatum L., with indurate floral bracts has not been previously reported. The objective of this study was to develop a technique for emasculating and hybridizing switchgrass. Emasculations were successful when the top of the stigmas could be seen through the translucent tips of the iemma and palea. Panicle branches containing 25 to 50 fertile florets were emasculated at this stage after removing excess panicle branches. Both sessile staminate florets and the fertile florets of a …

Teaching Large Classes: Unpacking The Problem And Responding Creatively, Elisa Carbone, James Greenberg

To Improve the Academy: A Journal of Educational Development

Teaching large classes well is a continuing challenge for many universities. This article looks at one university's systematic approach to the problem. It describes how faculty and administrators from all over campus were involved in a Continuous Quality Improvement (CQI) process, how the problems were clearly defined and recommendations made, and how the solutions that emerged also involved faculty from across the curriculum.

Developments In Initial Training And Certification Of University Teachers In The Uk: Implications For The Us, Graham Gibbs

To Improve the Academy: A Journal of Educational Development

Initial training of university teachers is developing in a different direction in the UK than in the US. It concentrates on tenure-track faculty rather than on TAs, on course design rather than on classroom practice, and is much more extensive. This paper contrasts UK and US faculty development practices and their implications. It describes two recent developments in the UK: the establishment of national certification of university teachers and the development of a national course for new faculty to help institutions meet the requirements of certification. The potential for similar mechanisms operating in the US is explored.

Holistic Faculty Development: Supporting Personal, Professional, And Organizational Well-Being, Glenda T. Hubbard, Sally S. Atkins, Kathleen T. Brinko

To Improve the Academy: A Journal of Educational Development

In recent years, higher education has begun to realize the great influence that faculty quality of life has on student learning and on overall institutional effectiveness. This article examines the interactive effect of personal, professional, and organizational well-being and describes a center that integrates four kinds of services-faculty development, employee assistance, health promotion, and organizational development-that work both separately and collaboratively. The result is a synergistic organization that is able to tackle complex institutional problems that could not be addressed by any one program alone.

Implications Of The Nature Of "Expertise" For Teaching And Faculty Development, Richard G. Tiberius, Ronald A. Smith, Zohar Waisman

To Improve the Academy: A Journal of Educational Development

Over the last two decades cognitive theorists have learned that the development of expertise goes beyond the accumulation of knowledge and skills: expertise includes the development of pattern recognition and learned procedures that enable practitioners to deal with problems effortlessly or intuitively. Even more recently, theorists are distinguishing experts from experienced non-experts by how they use the bonus time and energy gained from solving problems intuitively. Experts invest it in tackling problems that increase their expertise rather than reduce problems to previously learned routines. Some implications of these different views of expertise for teaching and faculty development are discussed.

Academic Morphing: Teaching Assistant To Faculty Member, Kathleen S. Smith, Patricia L. Kalivoda

To Improve the Academy: A Journal of Educational Development

This paper discusses the process by which graduate teaching assistants (TAs), participating in a longitudinal study, used their graduate TA experience to successfully survive the transition from being a teaching assistant to becoming a faculty member. A theoretical framework is presented that describes how individual characteristics of the TAs worked together with disciplinary, institutional, and departmental forces to shape a set of professional values. These professional values helped to form strategies for success: one set used for securing the first faculty position and the other set used to balance professional roles during the first year as a faculty member. These …

Infrared Ellpsometer/ Polarmeter System, Method Of Calibration, And Use Thereof, Daniel W. Thompson, Blaine D. Johs

Department of Electrical and Computer Engineering: Faculty Publications

A sample system investigation system, such as an ellipsometer or polarimeter system, for use in investigating sample systems with electromagnetic wavelengths in the infrared range, and a calibration method for compensating nonidealities in multi-dimensional system rotated and non-rotated component representing matricies, are disclosed. An essentially achromatic compensator of dual-rhomb construction, which introduces a (3*LAMBDA/4) phase shift, but essentially no deviation in the direction of propagation of a polarized beam of electromagnetic wavelengths caused to pass there through, even when said compensator is caused to continuously rotate, is also disclosed.

A New Radiosonde System For Profiling The Lower Troposphere, Brian R Corner, Robert D. Palmer

Department of Electrical and Computer Engineering: Faculty Publications

A new, inexpensive radiosonde transmitter and receiver system has been developed for measuring wind field inhomogeneities in the planetary boundary layer using multiple simultaneously launched balloons. The radio- sondes use a narrowband-frequency-modulated carrier signal to transmit atmospheric pressure and temperature information to a surface receiver. The pressure and temperature data transmitted by the radiosondes allow their height above the surface to be ascertained. In addition, the radiosondes can be tracked with a photographic camera system to provide the azimuth and elevation angles of the radiosondes during their ascent, so that their three-dimensional horizontal position can be determined. By tracking the …

Psychological And Physiological Causes And Consequences Of The Female Athlete Triad In Distance Runners, Patricia Sue Vincent

Graduate Research Papers

This paper was developed in order to identify psychological and physiological causes and consequences of the female athlete triad in distance runners. The most serious conditions of the female athlete triad are eating disorders, menstrual disorders, and bone disorders. Psychological factors have been implicated as the primary cause of disordered eating among this group of athletes. The disordered eating of a female distance runner can set off a sequence of physical health problems. An energy deficit, typical in endurance runners with eating difficulties, coupled with intense exercise training, may lead to lower reproductive hormones in the blood, amenorrhea, and reduced …

Production Of Ethers Of Gycerol From Crude Glycerol: The By-Product Of Biodiesel Production, Hossein Noureddini, W. R. Dailey, B. A. Hunt

Papers in Biomaterials

Methyl esters of fatty acids (also known as biodiesel), made from the transesterification of vegetable oils and animal fats with methanol, have shown a lot of promise as alternative diesel fuels. Glycerol is the inevitable by-product of the transesterification process. While there are existing markets for glycerol, a significant increase in availability of glycerol, resulting from the expanded use of vegetable oils and animal fats, would destabilize the glycerol market. Direct addition of glycerol to the fuel is not possible, however, derivatives of glycerol such as ethers have potential for use as additives with biodiesel, diesel or biodiesel-diesel blends. In …

A Pernicious Problem: The Absence Of Women From Administrative Roles, Marilyn Grady, Barbara Lacost, Frederick C. Wendel, Bernita Krumm

Department of Educational Administration: Faculty Publications

In 1972 Title IX, the vaccine against gender inequity, was unveiled. Title IX is a federal law making sex discrimination in schools illegal. Under Title IX, sex bias is outlawed in school athletics, career counseling, medical services, financial aid, admission practices, and the treatment of students. In 1974, Congress passed the Women's Educational Equity Act to fund research, materials, and training to help schools eliminate gender bias. In 1978, Congress broadened the Civil Rights Act to include educational services to eliminate gender bias. Under the redesigned civil rights legislation, ten sex desegregation assistance centers were created to assist teachers, parents, …

Substituted Polythiophenes From Highly Reactive Zinc Reagents, Reuben D. Rieke

Department of Chemistry: Faculty Publications

A novel Zerovalent zinc species and an organozinc reagent are disclosed. The zerovalent zinc species is directly pro duced by reaction of a reducing agent on a zinc salt, preferably Zn(CN)₂. The organozinc reagent results from the reaction of the zerovalent zinc species and an organic compound having one or more stable anionic leaving groups. These organozinc reagents include a wide spectrum of functional groups in the organic radical, and are useful in a variety of reactions schemes.

Conflicts Of Interest In Scientific Expert Testimony, Mark R. Patterson

Faculty Scholarship

Conflicts of interest have significant implications for the reliability of scientific expert testimony. However, the courts' treatment of conflicts is not always in accord either with the treatment of conflicts in scientific practice or with the particular problems that scientists' conflicts present in court. In response, this Article proposes two basic changes in the treatment of scientific expert testimony. First, courts should strive to separate issues of bias from issues of scientific validity-the two sets of issues are now conflated at times. Second, courts should pay more attention to biases of scientists who perform the research underlying expert testimony, whereas …

Mass Tort Litigation And Inquisitorial Justice, Howard M. Erichson

Faculty Scholarship

In the past decade, settlement class actions have become increasingly popular in mass tort litigation, having been used successfully in cases such as the Dalkon Shield litigation, the Bjork-Shiley heart valve litigation, and the orthopedic bone screw litigation. Although the Supreme Court's opinion in Amchem has engendered some confusion over the continued viability of mass tort settlement class actions, it appears that such settlements remain a dominant approach to resolving mass tort lawsuits. With increasing frequency, plaintiffs and defendants come to court holding hands, and courts must launch their own vigorous inquiries into the merits of the parties' proffered settlement. …

Stable Isotopes And Sediments From Pickerel Lake, South Dakota, Usa: A 12ky Record Of Environmental Changes, Antje Schwalb, Walter E. Dean

United States Geological Survey: Staff Publications

Sedimentological parameters and stable O- and C-isotopic composition of marl and ostracode calcite selected from a 17.7 m long core from the 8 m deep center of Pickerel Lake, northeastern South Dakota, provide one of the longest (ca. 12ky) paleoenvironmental records from the northern Great Plains. The late Glacial to early Holocene climate in the northern Great Plains was characterized by changes from cold and wet to cold and dry, and back to cold and wet conditions. These climatic changes were controlled by fluctuations in the positions of the Laurentide ice sheet and the extent of glacial Lake Agassiz. We …

Polyadenylation Of Vesicular Stomatitis Virus Mrna Dictates Efficient Transcription Termination At The Intercistronic Gene Junctions, Leroy N. Hwang, Nathan Englund, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The intercistronic gene junctions of vesicular stomatitis virus (VSV) contain conserved sequence elements that are important for polyadenylation and transcription termination of upstream transcript as well as reinitiation of transcription of downstream transcript. To examine the role of the putative polyadenylation signal 3' AUACU₇5' at the gene junctions in polyadenylation and transcription termination, we constructed plasmids encoding antigenomic minireplicons containing one or two transcription units. In plasmid-transfected cells, analyses of the bicistronic minireplicon containing the wild-type or mutant intercistronic gene junctions for the ability to direct synthesis of polyadenylated upstream, downstream, and readthrough mRNAs showed that the AUACU …

Interpreting Carnivore Scent-Station Surveys, Glen A. Sargeant, Douglas H. Johnson, William E. Berg

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The scent-station survey method has been widely used to estimate trends in carnivore abundance. However, statistical properties of scent-station data are poorly understood, and the relation between scent- station indices and carnivore abundance has not been adequately evaluated. We assessed properties of scent- station indices by analyzing data collected in Minnesota during 1986-93. Visits to stations separated by < 2 km were correlated for all species because individual carnivores sometimes visited several stations in succession. Thus, visits to stations had an intractable statistical distribution. Dichotomizing results for lines of 10 stations (0 or ≥ 1 visits) produced binomially distributed data that were robust to multiple visits by individuals. We abandoned 2-way comparisons among years in favor of tests for population trend, which are less susceptible to bias, and analyzed results separately for biogeographic sections of Minnesota because trends differed among sections. Before drawing inferences about carnivore population trends, we reevaluated published validation experiments. Results implicated low statistical power and confounding as possible explanations for equivocal or conflicting results of validation efforts. Long-term trends in visitation rates probably reflect real changes in populations, but poor spatial and temporal resolution, susceptibility to confounding, and low statistical power limit the usefulness of this survey method.

Sediment Ingestion Of Two Sympatric Shorebird Species, Clifford A. Hui, W. Nelson Beyer

United States Geological Survey: Staff Publications

Black-bellied plovers (Pluvialis squatarola) have short bills and primarily peck while foraging whereas Willets (Catoptrophorus semipalmatus) have long bills and primarily probe with bills open in sediments. Intestinal digesta were collected from these species at sympatric overwintering sites in southern California near San Diego to relate sediment ingestion to bill length and feeding behavior. Plover digesta contained an estimated 29% sediment, and Willet digesta an estimated 3% sediment. Techniques based on acid insoluble ash and on the elemental markers of Al, Fe, and Ti in digesta provided similar results. High Ca concentrations in Willet digesta along …
