Maintaining Privacy During Psychosocial Research On The International Space Station, Jennifer Boyd Ritsher, Nick Kanas, Stephanie Saylor

Journal of Human Performance in Extreme Environments

Conducting psychosocial research on the International Space Station (ISS) requires rigorous privacy precautions that exceed standard scientific human subject protocols. In our previous study involving crewmembers on Mir, and in our ongoing ISS work, special precautions were taken during each phase of the missions. Pre-flight, participants received detailed consent forms explaining that only group-level data would be presented, and they chose ID codes known only to them. In-flight, special procedures protected data during collection and transmission. Post-flight, our analytic strategy further masked participants’ identities, and participant representatives were invited to review manuscript drafts prior to publication. In this paper we …

Russia And Nato: Increased Interaction In Defense Research And Technology, Donald C. Daniel, Michael I. Yarymovych

Defense Horizons

As a member of both the Partnership for Peace and the North Atlantic Treaty Organization (NATO)–Russia Council (NRC), Russia enjoys remarkable status in an alliance formed principally to counter Soviet aggression. Active participation in one additional element of NATO—the Research and Technology Organization (RTO)—would offer unique opportunities to enhance relationships and mutual security. The RTO is the largest organization of its type in the world, has an extremely active program of work, and is eager to work with Russia.

Enhanced cooperation between NATO and Russia in defense-related research and technology would not be easy. Mistrust is an obstacle, as is …

The Effect Of The Hiv/Aids Epidemic On Africa's Truck Drivers, Christopher Kribs, Melanie Lee, Christine Roman, Shari Wiley, Carlos M. Hernandez-Suarez

Mathematics Faculty Publications - Archive

The AIDS epidemic is having a growing impact on the transport sector of the economy of sub-Saharan Africa, where long-distance truck drivers are at an increased risk of infection due to their frequent contacts with com- mercial sex workers. The spread of AIDS in the transport industry is especially signi¯cant to the economy, as truck drivers are largely responsible for trans- porting crops and supplies needed for daily subsistence. In this paper we analyze these e®ects via two models, one employing a switch and the other a Verhulst saturation function, to describe the rate at which new drivers are recruited …

Teaching Lessons Learned: The Exceed Teaching Model, Allen C. Estes, Ronald W. Welch, Stephen J. Ressler

Architectural Engineering

While the first five articles in this Journal of Professional Issues in Engineering Education and Practice (JPI) series covered a variety of teaching tools and techniques such as the chalkboard, questioning, drama, board notes, physical models, and demonstrations, the previous issue took a broader view and introduced a model instructional strategy. This strategy provides a conceptual framework that an instructor can use to develop classroom instruction in an organized and coherent manner. The strategy reflects the way that students actually learn and prompts the instructor to make conscious decisions about allocating responsibility for student learning and sequencing the contributing activities. …

Unintended Consequences Of Property Tax Relief: New York's Star Program, Tae Ho Eom, William Duncombe, John Yinger

Center for Policy Research

New York’s School Tax Relief Program, STAR, provides state-funded property tax relief for homeowners. Like a matching grant, STAR changes the price of public services, thereby altering the incentives of voters and school officials and leading to unintended consequences. Using data for New York State school districts before and after STAR was implemented, we find that STAR resulted in small increases in student performance along with significant decreases in the efficiency with which this performance is delivered and significant increases in school spending and property tax rates. These tax-rate increases magnify existing inequities in New York State’s education finance system.

Using Sociocultural Theory To Guide Teacher Use And Integration Of Instructional Technology In Two Professional Development Schools, Joan Whipp, Ellen Eckman, Leigh A. Van Den Kieboom

College of Education Faculty Research and Publications

This article demonstrates how sociocultural theories can be used to support strategic structuring of professional development activities for preservice and practicing teachers on technology use and integration. Examples are drawn from the authors' experiences with teachers in two professional development schools that participated in a four-year Preparing Tomorrow's Teachers in Technology (PT³) project. After a review of sociocultural theory and their context, the authors describe three "activity systems" in these schools: one for practicing teachers, one for preservice teachers, and a joint preservice/practicing teacher system. Important supports for use and integration of technology built into each of these …

Conjugacy Classes And Finite P-Groups, Edith Adan-Bante

Faculty Publications

Let G be a finite p-group, where p is a prime number, and a ∈ G. Denote by Cl(a) = {gag⁻¹| g ∈ G} the conjugacy class of a in G. Assume that |Cl(a)| = p ⁿ . Then Cl(a) Cl(a⁻¹) = {xy | x ∈ Cl(a), y ∈ Cl(a⁻¹)} is the union of at least n(p − 1) + 1 distinct conjugacy classes of G.

Induced Matter: Curved N-Manifolds Encapsulated In Riemann-Flat N+1 Dimensional Space, Harry I. Ringermacher, Lawrence R. Mead

Faculty Publications

Liko and Wesson have recently introduced a new five-dimensional induced matter solution of the Einstein equations, a negative curvature Robertson-Walker space embedded in a Riemann-flat five-dimensional manifold. We show that this solution is a special case of a more general theorem prescribing the structure of certain N+1 dimensional Riemann-flat spaces which are all solutions of the Einstein equations. These solutions encapsulate N-dimensional curved manifolds. Such spaces are said to "induce matter" in the submanifolds by virtue of their geometric structure alone. We prove that the N-manifold can be any maximally symmetric space. (c) 2005 American Institute of Physics.

Assessment Of Human Health Risks From Chemically Contaminated Lake Fishes In Greece, Eugene G. Maurakis, David V. Grimes, Dimitra Bobori, Rob Hale, Jennifer Jones

Virginia Journal of Science

Objectives were to conduct screening level surveys of locally consumed fish tissues in vicinities of two lakes (Kastoria and Pamvotis) in Greece to determine the presence of halogenated organic compounds and determine carcinogenic and non-carcinogenic human health risks associated with the consumption of sampled fish tissues. Results estimate the Incremental Lifetime Cancer Risks (ILCR) and Hazard Index (HI) values for the two local populations using site-specific population data. These results were compared to analyses conducted using U.S. Environmental Protection Agency default values in an effort to determine the applicability of USEPA default values to assessments of risks in non U.S. …

Preferred Learning Styles For Respiratory Care Students At Texas State University – San Marcos, Chris Russian

Internet Journal of Allied Health Sciences and Practice

Academic success includes setting goals, effective time management, and the match of teaching methods to learning style. It also depends on the educator and the manner in which material is presented. Learning style influences the retention of information and the depth of comprehension. If educators present material in a style that matches a student’s preferred learning style, then academic performance may improve. Assessing learning styles will benefit the student and the educator. Material retention will improve, thus improving test scores and limiting remediation. It is also important to determine if students, as a group, fit into a particular style or …

The Moxee City (Washington) Mammoth: Morphostratigraphic, Taphonomic, And Taxonomic Considerations, Karl Lillquist, Steve Lundblad, Bax R. Barton

All Faculty Scholarship for the College of the Sciences

A nearly complete, but highly fractured, proboscidean tusk was unearthed during parking lot construction near Moxee City in central Washington in May 2001. Schreger angle analysis revealed that the tusk was from a mammoth. AMS radiocarbon dating of the tusk established that the mammoth died 14,570 ¹⁴C yr BP. The age, combined with the biogeography of proboscidean finds in the Pacific Northwest, suggests the tusk is from a Columbian mammoth (Mammuthus columbi). The condition of the tusk and its association with basalt and crystalline erratics suggest that a locally derived tusk was swept up in the advancing …

A Dose-Response Curve For The Negative Bias Pressure Of An Intrathoracic Pressure Regulator During Cpr, Charles F. Babbs, Demetris Yannopoulos

Weldon School of Biomedical Engineering Faculty Publications

An intrathoracic pressure regulator (ITPR) is a device that can be added to the external end of an endotracheal tube to create controlled negative airway pressure between positive pressure ventilations. The resulting downward bias of the airway pressure baseline promotes increased venous return and enhanced circulation during CPR and also during hypovolemic shock. In the present study we exercised a mathematical model of the human cardiopulmonary system, including airways, lungs, a 4 chambered heart, great vessels, peripheral vascular beds, and the biomechanics of chest compression and recoil, to determine the relationship between systemic perfusion pressure during CPR and the value …

Optimal Control Theory Applied To A Difference Equation Model Of Cardiopulmonary Resuscitation, Eunok Jung, Charles F. Babbs, Suzanne Lenhart, Vladimir A. Protopoescu

Weldon School of Biomedical Engineering Faculty Publications

Objective: To apply the mathematical techniques of optimal control theory (OCT) to a validated model of the human circulation during cardiopulmonary resuscitation (CPR), so as to discover improved waveforms for chest compression and decompression that maximize the systemic perfusion pressure (SPP). Methods: The human circulatory system is represented by seven difference equations, which describe the pressure changes in systemic vascular compartments caused by chest compression. The forcing term is the intrathoracic pressure generated by the external chest compression, which is taken as the “control” variable for the system. The optimum waveform of this forcing pressure as a function of time, …

Dynamic Modeling Of Crew Performance For Long-Duration Space Missions, Sara Goudarzi, A. J. Both, Jim Cavazzoni, Alexander Kusnecov

Journal of Human Performance in Extreme Environments

Crew time is one of the most valuable and limited resources during long-duration space missions. Crew time requirements fluctuate depending on variations in crew performance. The limited number of crewmembers, resources, and the myriad of tasks to be performed leave a tight schedule for crewmembers during long-duration space missions. This schedule needs to account for potential interventions (stress events) that may alter predicted performance and thus scheduling. A dynamic crew model using a stochastic Auto Regressive Integrated Moving Average (ARIMA) model of interrupted time series was developed to account for the effects of potential stress events on crew performance. This …

Determinants Of Repeat Visitation For Las Vegas “Locals” Casinos, David D. Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

The proliferation of gaming is unprecedented. As many states look to gaming as a source of revenue for a poor fiscal policy, this research becomes more valuable. Many people fail to make the correlation between these new jurisdictions, Tribal or Indian gaming opportunities, and the “locals” market. The argument is, not many people are traveling to Barona or Harrah’s Rincon outside of San Diego, California for their vacation from New York City. Therefore, these primary markets are considered to be more localized. Localized markets could be referred to as geographic segmentation as opposed to other segmentation strategies. The strengths of …

Cross-Cultural Vincentian Leadership: The Challenge Of Developing Culturally Intelligent Leaders, Marco Tavanti Ph.D.

Vincentian Studies

As the Hay-Vincentian Leadership Project (HLP) becomes international in scope, Vincentian values must be applied in and sometimes adapted to cross-cultural contexts. The concepts of cultural diversity, cultural competence, and cultural intelligence are explained in general and against a Vincentian background. Qualities that make leaders effective in cross-cultural situations are explored. Vincent de Paul set an example for such success in the preparation he mandated for those going on foreign missions and in the sensitivity he showed in his own work with people from other cultures. Culture’s relationship to leadership is examined using the work of the anthropologist Edward Hall …

Multifractal Structure In Nonrepresentational Art, Jonas R. Mureika, C. C. Dyer, G. C. Cupchik

Physics Faculty Works

Multifractal analysis techniques are applied to patterns in several abstract expressionist artworks, painted by various artists. The analysis is carried out on two distinct types of structures: the physical patterns formed by a specific color (“blobs”) and patterns formed by the luminance gradient between adjacent colors (“edges”). It is found that the multifractal analysis method applied to “blobs” cannot distinguish between artists of the same movement, yielding a multifractal spectrum of dimensions between about 1.5 and 1.8. The method can distinguish between different types of images, however, as demonstrated by studying a radically different type of art. The data suggest …

Natural And Synthetic Viniferins Associated With The Grapevine Disease Young Vine Decline, David Michael Mcginnis

Chemistry & Biochemistry Theses & Dissertations

Grapevine disease has been thc subject of intense research amongst viticulturists over the last few decades, especially during the 1990's. There has been discoveries that suggest grapevine disease is commonly caused by fungal pathogens. One of the most common fungi that the vine may become infected by is known as Botrytis cinerea. B. cinerea is capable of attacking the grapevine which in turn will lead to bunch rot in the grape clusters. This disease has been researched in great detail during the past several years and is one of only few microorganisms that have actually been identified. Phaeoacremrmium chnlmydospnrum …

A Model For Recruiting And Training Youth Development Volunteers In Urban Areas, Martin H. Smith, H Steve Dasher, Donald J. Klingborg

Journal of Extension

A model for recruiting and training volunteers for 4-H Youth Development Programs in urban areas was designed and evaluated. Utilizing a formal course at a community college to recruit and train volunteers, the model was effective in developing and enhancing their skills. As part of their course requirements, volunteers applied their skills by implementing a science literacy program with elementary-age children in after-school settings. Their efforts were effective; participating children's science process skills showed significant improvements. Academic and community service credit served as rewards for volunteers' participation.
