Being Outside Learning About Science Is Amazing: A Mixed Methods Study, Michelle L. Weibel
UNLV Theses, Dissertations, Professional Papers, and Capstones
This study used a convergent parallel mixed methods design to examine teachers' environmental attitudes and concerns about an outdoor educational field trip. Converging both quantitative data (Environmental Attitudes Scale and teacher demographics) and qualitative data (Open-Ended Statements of Concern and interviews) facilitated interpretation. Research has shown that adults' attitudes toward the environment strongly influence children's attitudes regarding the environment. Science teachers' attitudes toward nature and attitudes toward children's field experiences influence the number and types of field trips teachers take. Measuring teacher attitudes is a way to assess teacher beliefs.
The one day outdoor field trip had significant outcomes for …
Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii
Risk-Based Critical Infrastructure Priorities For Emp And Solar Storms, George H. Baker Iii
George H Baker
Two electromagnetic phenomena have the potential to create continental-scale disasters. The first, nuclear electromagnetic pulse (EMP), results from a nuclear detonation high above the tropopause. The second, a major solar storm, or "solar tsunami" occurs naturally when an intense wave of charged particles from the sun perturbs the earth's magnetic field. Both phenomena can debilitate electrical and electronic systems necessary for the operation of infrastructure systems and services. One reason why a U.S. protection program has yet to be initiated is that policy makers continue to wrestle with the question of where to begin, given the Department of Homeland Security’s …

Interactive Real-Time Embedded Systems Education Infused With Applied Internet Telephony, Kyle Persohn, Dennis Brylow
Interactive Real-Time Embedded Systems Education Infused With Applied Internet Telephony, Kyle Persohn, Dennis Brylow
Mathematics, Statistics and Computer Science Faculty Research and Publications
The transition from traditional circuit-switched phone systems to modern packet-based Internet telephony networks demands tools to support Voice over Internet Protocol (VoIP) development. In this paper, we introduce the XinuPhone, an integrated hardware/software approach for educating users about VoIP technology on a real-time embedded platform. We propose modular course topics for design-oriented, hands-on laboratory exercises: filter design, timing, serial communications, interrupts and resource budgeting, network transmission, and system benchmarking. Our open-source software platform encourages development and testing of new CODECs alongside existing standards, unlike similar commercial solutions. Furthermore, the supporting hardware features inexpensive, readily available components designed specifically for educational …
Risk-Based Critical Infrastructure Protection Priorities For Emp And Solar Storms, George H. Baker Iii
Risk-Based Critical Infrastructure Protection Priorities For Emp And Solar Storms, George H. Baker Iii
George H Baker
The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP. As with protecting infrastructure against any hazard, it will be important to take a risk-based priority approach for EMP, recognizing that it is fiscally impracticable to protect everything. In this regard, EMP is particularly challenging in that it interferes with electrical and electronic data, control, transmission, and communication systems organic to nearly all infrastructures in a simultaneous and wide-scale manner. And, for nuclear burst altitudes of 100s of kilometers, the exposed geography …
Chemical Education Experiences From The English Language Learner Perspective, Annette Flores
Chemical Education Experiences From The English Language Learner Perspective, Annette Flores
Theses and Dissertations - UTB/UTPA
The Rio Grande Valley (RGV) is a region populated by Spanish-speaking immigrants and their descendants producing a large English Language Learner (ELL) student population. ELLs have historically had low literacy rates and achievement levels when compared to their counterparts. In order to address this achievement gap, previous research efforts and curriculum interventions have focused on language acquisition as being the determining factor in ELL education, with little attention given to academic content acquisition. More current research efforts have transitioned into English language acquisition through academic content instruction; this present research study specifically focuses on ELL experiences in chemistry. Participants were …

Emp: A Brief Tutorial, George H. Baker Iii
Emp: A Brief Tutorial, George H. Baker Iii
George H Baker
A nuclear detonation at altitudes from about 30 to 500 kilometers generates a strong electromagnetic pulse (EMP) that propagates to points on the ground within the line-of-sight of the burst. For bursts above 100 kilometers, electronics can be affected over continental scale areas. The EMP induces large voltages and currents in antennas and cables of electronic systems that will upset operation or damage circuit components if protection measures are not present. The article provides a brief tutorial on EMP environments, effects and protection.
High Power Electromagnetic Weapons: A Brief Tutorial, George H. Baker Iii
High Power Electromagnetic Weapons: A Brief Tutorial, George H. Baker Iii
George H Baker
High power electromagnetic weapons, also referred to as high power radiofrequency (HPRF) weapons, are a type of directed energy weapons. The system effects of high power electromagnetic environments are well recognized by world scientific and military communities. Former CIA Director John Deutch has said that, "the electron is the ultimate precision-guided weapon." In the course of the investigation ofnuclear EMP effects on electronics during the Cold War period, it became evident that garden variety, unprotected electronics would malfunction, in some cases burn out, in the presence of electromagnetic fields in the hundreds to thousands of volts per meter. The EMP …

Income Inequality And Spatial Distribution : Firm Location, Product Quality And Welfare Of Poor., Namrata Gulati Dr.
Doctoral Theses
The key idea explored in this thesis is the following: though being poor in itself is a huge disadvantage, the situation might be influenced considerably by the type of neighbourhood the poor lives in as private establishments like educational institutions, health care facilities or credit institutions take both the location and income mix of people into account while making strategic decisions like whether to enter into the neighbourhood at all, and, upon entry, what price and quality to choose for their products and services. Is staying with the rich a virtue for the poor or a source of resentment? Are …
Tangible Interaction And Learning: The Case For A Hybrid Approach, Michael S. Horn, R. Jordan Crouser, Marina U. Bers
Tangible Interaction And Learning: The Case For A Hybrid Approach, Michael S. Horn, R. Jordan Crouser, Marina U. Bers
Computer Science: Faculty Publications
Research involving tangible interaction and children has often focused on how tangibles might sup- port or improve learning compared to more traditional methods. In this paper, we review three of our research studies involving tangible computer programming that have addressed this question in a variety of learning environments with a diverse population of children. Through these studies, we identify situations in which tangible interaction seems to offer advantages for learning; how- ever, we have also identify situations in which tangible interaction proves less useful and an alternative interaction style provides a more appropriate medium for learning. Thus, we advocate for …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
In the State of Utah, both state and federal government agencies work together to provide special education services to eligible children. An important part of this effort is to document the effectiveness of the program, which can be measured in terms of the outcomes, namely, the progress of the individual children. This information can help identify both strengths and weaknesses of special education programs within the state, which in turn can lead to program improvements and better allocation of resources. This report describes a software system that supports the tracking of child and program outcomes for special education within Utah. …

Public Policy, Long Run Growth And Economic Transition From Agriculture To Industrial Mass Production., Rudrani Bhattacharya Dr.
Doctoral Theses
It has been recognized that the heart of the development process lies on the transformation of an economy from traditional activities in agriculture to industrial activities. As emphasized by Lewis (1954), the movement of labor from primary sector to industry is conducive to the rise of economy’s savings and investment rate and thus fostering economic growth. The core of this paradigm is the historically observed rapid growth in today’s developed countries associated with expansion of industrial activities.It is well-documented by now that at least over a few centuries leading up to 1800 AD there was little change in the world …

Wealth Inequality And Economic Performances., Sahana Roy Chowdhury Dr.
Doctoral Theses
Ever since the inception of Development Economics as a separate discipline inequality has been a major area of extensive study. Economists and researchers have deliberated both on the causes and the effects of inequality in a wide range of treatise, books and essays. So far, in this regard, two fundamental approaches came across viz., the Classical approach and the Credit Market Imperfection approach. The Classical approach was originated by Smith (1937) and was further interpreted and developed by Keynes (1920), Lewis (1954), Kaldor (1957), and Bourguignon (1981). According to this approach, savings rate is an increasing function of wealth and …

Mapping The Organizational Relations Within Physical Security’S Body Of Knowledge: A Management Heuristic Of Sound Theory And Best Practice, Richard Coole, David J. Brooks
Mapping The Organizational Relations Within Physical Security’S Body Of Knowledge: A Management Heuristic Of Sound Theory And Best Practice, Richard Coole, David J. Brooks
Australian Security and Intelligence Conference
Security Science education at university levels is still in its infancy, with little agreement towards knowledge, curriculum and competency. Therefore, it is essential that educators draw on relevant literature highlighting means of efficient and effective knowledge transfer for tertiary students within the Security Science domain. Such knowledge transfer will reduce the gap between academic knowledge (explicit) and professional competency (tacit knowledge). This paper presents phase one of a multiphase study. A qualitative “systems based knowledge structure” of security domain categories has been conceptually mapped as a domain heuristic. The heuristic drew on research highlighting that experts have both richer depths …

Environmental & Occupational Health Faculty Publications
Following the discovery of quagga mussels in Lake Mead, Nevada-Arizona, USA, a variety of federal, state and regional agencies set up monitoring programs to evaluate and gain information to help minimize the impacts, or potential impacts, of quagga mussels to their facilities and lake ecology. While the agencies have worked closely and shared monitoring data and findings from the beginning of the infestation, there has been no documented comprehensive monitoring program to describe and record the various quagga mussel-related monitoring needs. Ad hoc interagency quagga mussel meeting representatives established an Interagency Monitoring Action Plan (I-MAP), which outlines agency objectives related …
Thermal Analysis As An Important Research Tool For Colleges And Universities, Jeffrey Allen Fruscella
Thermal Analysis As An Important Research Tool For Colleges And Universities, Jeffrey Allen Fruscella
ETD Archive
Three experiments were performed to demonstrate that thermal analysis is an important tool for use in colleges and universities for conducting scientific research. The first experiment used thermogravimetry, differential scanning calorimetry and thermal mechanical analysis to compare polymer resins from two ResinKits®, one from 1994 and the other from 2010. Analysis was done to determine if resins from the 1994 kit were viable standards. The experiments showed significant thermal differences between select resins and it was concluded that resins form the 1994 ResinKit® are no longer acceptable as standards.The second experiment used thermogravimetry and differential scanning calorimetry to determine the …
