Technology And Mathematics Standards: An Integrated Approach, Chris Merrill, Mark Comerford

Publications

The article focuses on the use of standards-based teaching and learning that has been gaining significant attention in the education world. State and national associations now base their specific subject area or discipline solely on standards, i.e., International Technology Education Association (ITEA), National Council of Teachers of Mathematics (NCTM), National Science Education Association (NSEA). Moreover, at the public school level, state boards of education are holding school districts accountable for teaching standards-based curricula. It is with the latter definition in mind that the authors created a standards-based, integrated technology and mathematics lesson using the design and construction of stair systems.

Effect Of Day Length On Sleep Habits And Subjective On-Duty Alertness In Irregular Work Schedules, June J. Pilcher, Heather M. Teichman, Stephen Popkin, Krista Hildebrand, Michael Coplen

Publications

The human circadian system is sensitive to environmental conditions, such as those created by shift work, that affect the timing and duration of sleep. Previous research on the effects of shift work, however, has focused primarily on regularly scheduled shifts. Few studies have focused on irregular and unpredictable on-call shift systems, such as those found in much of railroad operations. The purpose of the current study was to examine the effect of irregular shift systems experienced by locomotive engineers on the length of sleep-wake periods and the effect of different length sleep-wake periods on self-reported sleep quantity, sleep quality, and …

The Reactivity Of Dissolved Organic Matter For Disinfection By-Product Formation, Mehmet Kitis, Tanju Karanfil, James E. Kilduff

Publications

Dissolved organic matter (DOM) in 6 water samples collected from 4 surface waters were fractionated using some or all of 5 physicochemical separation processes (activated carbon and XAD-8 batch adsorption, alum coagulation, ultrafiltration (UF), and XAD-8 column fractionation). Activated carbon, XAD-8 batch adsorption and alum coagulation processes fractionated DOM by preferentially removing high-SUVA components from solution. The XAD-8 column method fractionated DOM into hydrophobic and hydrophilic components while UF separated DOM into different size fractions. Over 40 DOM fractions, characterized using carbon-normalized (specific) ultraviolet absorbance (SUVA), were obtained for each water. Trihalomethane (THM) and haloacetic acid (HAA_9) formation after chlorination …

A Multi-Objective Decision-Making Framework For Transportation Investments, Mashrur Chowdhury, Pulin Tan

Publications

This paper presents a framework based on multi-objective optimization that can be used to generate and analyze the most desirable transportation investment options based on their objectives and constraints. The framework, which is based on the surrogate worth trade-off analysis, could be applied to both discrete or continuous decision-problem scenarios. In a discrete problem, a predefined set of alternatives is available, whereas continuous problems are not characterized by a predefined set of alternatives. This framework was applied with the data generated for a Capital Beltway Corridor investment study. The multi-objective decision-making framework was found to be adaptable to this typical …

Critical Issues And Problems In Technology Education, Robert C. Wicklein

Publications

The article informs that to address the need of identifying a comprehensive base for the critical issues and problems, research was conducted to ascertain the perspectives of classroom teachers, university professors, and supervisors of technology education. In addition, the entire population of 132 university department heads/program leaders in technology teacher education, as well as the total population of 55 state and regional supervisors, were selected to receive the survey questionnaire. The critical problem items, insufficient quantities of qualified technology education teachers, inadequate understanding by administrators and counselors concerning technology education, and inadequate understanding by general populace concerning technology education, were …

Are Four-Year Universities Better Than Two-Year Colleges At Preparing Students To Pass The Faa Aircraft Mechanic Certification Written Examinations?, Jeffrey Bruce Summey, Marian C. Schultz, James T. Schultz

Publications

This study evaluates differences between two-year and four-year schools offering a Federal Aviation Administration (FAA) Part 147 aviation maintenance technician program. The actual average test scores were analyzed to determine whether students from four-year university programs were better prepared for the test than students from two-year college or technical school programs. Test scores can be viewed as a direct indication of the quality of the aviation maintenance programs at these schools. The study found that there was no statistically significant difference in the test scores between two-year college and four-year university students taking the FAA examinations. These results support previous …

Research Readiness Self-Assessment: Assessing Students' Research Skills And Attitudes, Lana Ivanitskaya, Ryan Laus, Anne Marie Casey

Publications

Librarians and learning researchers at Central Michigan University collaboratively developed an online tool that assesses how student research attitudes and perceptions correlate to their actual research skills in order to educate them about state-of-the-art library resources and prepare them to write high-quality research papers. This article describes the reasons for developing the assessment as well as the design process and technical characteristics.

A Historical Overview Of Internet Reference Services For Distance Learners, Anne Marie Casey

Publications

The advent of library services and collections on the Internet revolutionized reference services to students enrolled in distance learning programs. Prior to the Internet, reference librarians who supported distance learning programs had few methods, and many of them costly, to provide the equivalent library services advocated by the ACRL Guidelines. Through the Internet, these librarians were able to approximate the services and resources that had always been available to students who came into the library. This article describes the development of reference services on the Internet in a variety of libraries that support distance learners.

Lawsuit Abandonment Options In Possibly Frivolous Litigation Games, Peter H. Huang

Publications

This paper develops a new theory of possibly frivolous litigation by focusing on a plaintiff's options to unilaterally abandon a lawsuit. Federal Rule of Civil Procedure 41(a)(1)(i) and its various state law counterparts permit, under certain circumstances, a plaintiff to voluntarily dismiss her lawsuit without prejudice. This paper's options approach to litigation, including quite possibly, frivolous litigation is placed in the context of the literature of economic models about litigation in general and frivolous litigation in particular. This paper demonstrates that possibly frivolous lawsuits will be filed and settled when the values of a plaintiff's options to unilaterally abandon litigation …

Women Choosing Diverse Workplaces: A Rational Preference With Disturbing Implications For Both Occupational Segregation And Economic Analysis Of Law, Scott A. Moss

Publications

Despite women's dramatic labor market gains, there remains a striking degree of occupational segregation by gender. Analysts typically blame discrimination or women's work/family priorities. This Article offers a different explanation.

It is hard for women choosing jobs or occupations to know where they will face discrimination, particularly since recent judicial decisions eliminated certain employer signals that once differentiated fair and discriminatory firms. One way women can effectuate a preference for nondiscriminatory workplaces is by choosing gender-diverse workplaces. Nondiverse workplaces often are not female-friendly, and discrimination may be the reason they are nondiverse. In economic terms, women rationally use level of …

Contract Formation In Imperfect Markets: Should We Use Mediators In Deals?, Scott R. Peppet

Publications

This Article asks a simple question: Could third-party mediators be helpful in deals, just as they are in disputes? This Article makes a theoretical argument for such interventions, but also presents preliminary empirical evidence suggesting that transactional mediation may already be taking place.

Protecting The Lady From Toledo: Post-Usa Patriot Act Electronic Surveillance At The Library, Susan Nevelow Mart

Publications

Library patrons are worried about the government looking over their shoulder while they read and surf the Internet. Because of the broad provisions of the USA PATRIOT Act, the lack of judicial and legislative oversight, the potential for content overcollection, and the ease with which applications for pen register, section 215 orders, or national security letters can be obtained, these fears cannot be dismissed.

Grb 011121: A Collimated Outflow Into Wind-Blown Surroundings, J. Greiner, S. Klose, M. Salvato, A. Zeh, R. Schwarz, D. H. Hartmann, N. Masetti, B. Stecklum, G. Lamer, N. Lodieu

Publications

We report optical and near-infrared follow-up observations of GRB 011121 collected predominantly at ESO telescopes in Chile. We discover a break in the afterglow light curve after 1.3 days, which implies an initial jet opening angle of about 9°. The jet origin of this break is supported by the fact that the spectral energy distribution is achromatic during the rst four days. During later phases, GRB 011121 shows signi cant excess emission above the flux predicted by a power law, which we interpret as additional light from an underlying supernova. In particular, the spectral energy distribution of the optical transient …

Algal Vs. Macrophyte Inputs To Food Webs Of Inland Saline Wetlands, E. Andrew Hart, James R. Lovvorn

Publications

Invertebrate food webs in wetlands were traditionally thought to be fueled mainly by decaying macrophytes, but recently it has been recognized that microalgae may be more important. In particular, the paradigm that shredders of vascular plant litter dominate food web processes may not apply to many wetlands where shredders are rare and microalgae more abundant. This issue is complicated by potential consumption of flocs of dissolved organic matter (DOM) released from living plants, and of exopolymer secretions (EPS) from both autotrophic and heterotrophic microbes. In Wyoming, we used gut contents and stable isotopes to investigate organic matter sources for the …

Scale-Dependent Associations Among Fish Predation, Littoral Habitat, And Distributions Of Crayfish Species, James E. Garvey, Jessica E. Rettig, Roy A. Stein, David M. Lodge, Steven P. Klosiewski

Publications

To predict how species establish and disperse within novel communities, the spatial scale at which competition, predation, and habitat interact must be understood. We explored how these factors affect the distribution and abundance of the exotic crayfishes Orconectes rusticus and O. propinquus and the native O. virilis at both the site-specific and whole-lake scales in northern Wisconsin lakes. During summer 1990, we quantified crayfish, fish predators, and fish diets in cobble and macrophyte sites in Trout Lake, comparing resulting patterns to those in 21 lakes surveyed during summer 1987. Within and across lakes, fish abundance was unrelated to habitat. Within …

A Presolar Galactic Merger Spawned The Sic-Grain Mainstream, Donald D. Clayton

Publications

The merger of a metal-poor satellite galaxy with the Milky Way about 5–6 Gyr ago is postulated to resolve three great unexplained conflicts presented by mainstream presolar stardust SiC grains. The model allows all of the asymptotic giant branch (AGB) carbon stars that donated these grains to have been formed nearly simultaneously in a starburst generated by gaseous mixing, despite their great apparent age differences when evaluated in terms of Galactic chemical evolution (GCE). The model explains why a precisely measured lin-ear correlation exists between the ratios 29Si/28Si and 30Si/28Si in the initial compositions of those AGB stars. It suggests …

Aspidoderid Nematodes From Bolivian Armadillos, With The Description Of A New Species Of Lauroia (Heterakoidea: Aspidoderidae), F Agustín Jiménez-Ruiz, Scott L Gardner

Publications

One nine-banded armadillo (Dasypus novemcinctus) and 1 yellow armadillo (Euphractus sexcinctus) were necropsied in the field during an expedition to collect parasites of mammals in Bolivia. A total of 205 Aspidodera binansata Railliet and Henry, 1913 (Heterakoidea: Aspidoderidae), and 40 specimens of Lauroia bolivari n. sp. (Heterakoidea: Aspidoderidae) were recovered from the cecum and large intestines of D. novemcinctus and E. sexcinctus. Aspidodera esperanzae Fujita et al., 1995, is proposed as a junior synonym of A. binansata based on the structure of the cordons on the hood. Lauroia bolivari n. sp. has an undercut cephalic …
