The Law of Church and State: Public Aid to Sectarian Schools
One of the most difficult issues of constitutional law concerns the extent to which the establishment of religion clause of the First Amendment imposes constraints on the provision of public aid to private sectarian schools. This report gives a brief overview of the evolution of the Court’s interpretation of the establishment clause in this area and itemizes the categories of aid that have been addressed by the Court and held to be constitutionally permissible or impermissible, both at the elementary and secondary school level and at the college level.

Wind Resource Development Project for Armenia
Armenia has few proven reserves of natural energy and is dependent on long, unreliable transport lines for oil and gas. Preliminary studies indicate that the wind energy potential in Armenia is more than 500 megawatts (MW), assuming a reasonable fraction of 10% of the land area in the high-wind zones. Over the long term, the Armenian government intends to meet 8%--10% of its electric consumption needs by grid-connected wind turbines. The goals of this project are to enhance Armenia's energy security, mitigate the environmental damage of conventional sources of energy, reduce future carbon dioxide emissions, build an environmentally sound and sustainable model for economic development, and promote trade between the U.S. and Armenia. The project is being funded by the Cafesjian Family Foundation, a private foundation based in the United States in Naples, Florida, with the participation of Ecotrade, Inc. of Glendale, California. The National Renewable Energy Laboratory (NREL) is providing technical assistance. As part of the wind energy development project, the authors conducted a preliminary wind-energy resource assessment for some regions in Armenia. This activity provided valuable information needed to facilitate the commercialization of wind farms in Armenia and to lay the groundwork for subsequent wind resource activities. This …

Overview of Grand Unified Models and their predictions for neutrino oscillations
A brief overview of Grand Unified Models is presented with some attention paid to their predictions for neutrino oscillations. Given the well-known features of the two non-unified standard models, SM and MSSM, a listing of the features of classes of unified models is given, where a GUT flavor symmetry and/or family symmetry are introduced to reduce the number of model parameters. Some general remarks are then made concerning the type of predictions that follow for the neutrino masses and mixings.

The Design of a Novel Survey for Small Objects in the Solar System
We evaluated several concepts for a new survey for small objects in the Solar System. We designed a highly novel survey for comets in the outer region of the Solar System, which exploits the occultations of relatively bright stars to infer the presence of otherwise extremely faint objects. The populations and distributions of these objects are not known; the uncertainties span orders of magnitude! These objects are important scientifically as probes of the primordial solar system, and programmatically now that major investments may be made in the possible mitigation of the hazard of asteroid or comet collisions with the Earth.

To Include or not to Include: Early Childhood Preservice Educators' Beliefs, Attitudes, and Knowledge about Students with Disabilities
The first purpose of this study was to develop and validate the Inventory of Opinions About Persons with Disabilities (IOPD). The IOPD was developed to collect preservice early childhood educatorsself-report data related to inclusion. A total of 332 participants enrolled in graduate programs in a college of education served as the validation sample. After validation and revision of the IOPD, the researcher used the instrument to investigate preservice early childhood educators beliefs, attitudes, and knowledge about students with disabilities and their inclusion in general education classrooms. Data were collected from 172 participants from 10 universities in Texas during their student teaching/final intern semesters. This research demonstrated that an instrument, the IOPD, could be developed to effectively measure preservice early childhood educators beliefs, attitudes, and knowledge about the inclusion of children with disabilities in their classrooms. The participants reported positive self-perceptions (mean = 2.0388) about their beliefs and attitudes toward inclusion. However, the participants reported less positive attitudes about training (mean = -.09884). Discriminant function analyses indicated a negligible statistical effect for type of program (professional development school or traditional) and a statistically significant effect for preferred classroom setting (non-inclusive, special education, inclusive). Further research with the same participants or similar …

Attitudes Toward Computer Use and Gender Differences Among Kuwaiti Sixth-Grade Students
Because computer use become more and more important in the educational environment, the attitudes of students toward computer may play an important role in their learning success. This study investigated the attitudes toward computers and gender differences of sixth-grade Kuwaiti students and examined the relationships between students attitudes toward computers and school, motivation/persistence, study habits, empathy, creative tendencies, and achievement in the Informatics field. The Computer Attitude Questionnaire (CAQ), translated from the English into Arabic Language for this study, was originally developed by Knezek and Miyashita for the Texas Center for Educational Technology (University of North Texas). The CAQ was administered to a random cluster sample of 10 public middle schools: (5 boys and 5 girls schools), with a total of 562 students, (265 boys and 297 girls), in the State of Kuwait during the academic year 1999-2000. The pilot test was conducted to calculate the reliability with Cronbachs alpha = .87 for the CAQ Arabic version. This study found positive attitudes toward computer use (mean = 3.31 on 4-point Likert-scale); however, girls had significantly more positive attitudes toward computers (mean = 3.36) than did boys (mean = 3.26). It also found statistically significant correlations between attitudes toward computers and …

The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait
Change is best carried out by individual teachers, and, thus, identifying and resolving teachers concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis …

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning
The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learners performances while soldering. The 2 x 2 factorial model with interaction …

Muons and neutrinos at high-energy accelerators
Background levels in detectors and radiation problems at future colliders--whether pp, e{sup +}e{sup {minus}} or {mu}{sup +}{mu}{sup {minus}} are in large part determined by the presence of muons. Neutrinos from muon decay at muon colliders or storage rings are highly collimated and propagate outward within a narrowdisk in which significant radiation doses persist out to very large distances. This paper highlights physics models and Monte Carlo algorithms developed mainly for studying these problems as well as some typical results.

Transition From in-Plane to Out-of-Plane Azimuthal Enhancement in Au+Au Collisions
The incident energy at which the azimuthal distributions in semi-central heavy ion collisions change from in-plane to out-of-plane enhancement--E{sub tran} is studied as a function of mass of emitted particles, their transverse momentum and centrality for Au+Au collisions. The analysis is performed in a reference frame rotated with the sidewards flow angle ({Theta}{sub flow}) relative to the beam axis. A systematic decrease of E{sub tran} as function of mass of the reaction products, their transverse momentum and collision centrality is evidenced. The predictions of a microscopic transport model (IQMD) are compared with the experimental results.
