Developing A Program Evaluation Instrument For Texas 4-H: A Work In Progress, Martha E. Couch

Journal of Extension

The Texas 4-H Program is a continuously growing organization that has identified a major need to implement a standardized evaluation instrument to measure its impact and effectiveness. This article summarizes the development of the evaluation instrument by describing factors that surfaced to measure effective 4-H programs. This instrument will be available from the Texas 4-H Web page for all program coordinators to download and implement. Ultimately, this instrument will allow the Texas 4-H and Youth Development Program to become a more accountable organization, adding substance to an increasingly growing program.

Lithospheric Structure Of The Basin And Range Province-Southwestern Colorado Plateau. Southeastern California, Southern Nevada, And Western Arizona, Nigel Oakley Hicks

Open Access Theses & Dissertations

The Basin and Range Province of the western United States is an unusually wide continental rift zone and its structure and evolution have been the topic of much debate. Active source seismic surveys within the Basin and Range Province have delineated a relatively uniform crustal thickness (-30 km) despite varying magnitudes of crustal extension (<10-300 km). Large scale Cenozoic crustal extension has exhumed midcrustal rocks (from 10-20 km depth) along low angle detachment faults to create metamorphic core complexes (exposed lower plate rocks). In contrast to the extreme amounts of extension and internal deformation of the Basin and Range, the Colorado Plateau has remained a relatively rigid block, with a crustal thickness of 40-50 km, apparently resistant to the deformation processes that have shaped the Basin and Range observed today. In general, geophysical surveys reveal a significant contrast in crustal structure between the Basin and Range and it's transition into the Colorado Plateau.

The debate about the origin of the Basin and Range has underscored the need for additional geophysical constraints. Thus in this study, a regional analysis of lithospheric structure in the region of southeastern California, southern Nevada, and western Arizona that includes the Basin and Rangesouthwestern …

An Evaluation Of Progressively Loaded Root Form Dental Implants Placed Into Extraction Sites, Franco Audia

Loma Linda University Electronic Theses, Dissertations & Projects

The conventional protocol for placement of endosseous root form implants requires up to twelve months of ossification of the extraction socket prior to implant placement. An alternative approach includes the immediate placement of dental implants into a prepared extraction socket following tooth removal. The purpose of this study was to compare conventionally placed non-loaded dental implants with those placed immediately into extraction sockets and progressively loaded in adult patients. A total of twenty implants were placed in eighteen patients and followed for a twelve-month period.

Clinically, no significant differences between conventional and immediately placed dental implants were observed. Radiographically, immediately …

A Model For Hiv/Aids Risk Behaviors Of Students In Armenia, Talin Babikian

Loma Linda University Electronic Theses, Dissertations & Projects

Without a cure in now its third decade, AIDS is a concern for both the medical and social science disciplines. Most at risk for a nationwide AIDS epidemic are developing countries, which often lack the necessary resources and knowledge to minimize the spread of the disease. There are an estimated 1500 HIV cases in Armenia, 81.5% of which occur in the 20-39 age group. Armenia’s current economic and political instability, increase in sexually transmitted infections (STI), prostitution, and injecting drug use, and the alarming incidence rates in neighboring countries amplify its risk for a national epidemic.

The goals of this …

An Examination Of Hangover Effects On Pilot Performance, Joanne W. Bates

Theses and Dissertations

The present study investigated the influence of ethanol on aviation performance 10 hours after subjects finished drinking. The results of past studies concerning alcohol hangover effects are conflicting. Some studies have shown that alcohol hangovers affect complex cognitive performance, while other studies have not found effects.

One aim of the present study was to observe hangover effects after strong and medium doses of alcohol with an intervening night of sleep. Furthermore, previous research has found that use of ethanol increased variability in flying performance. This implies that hangover effects influence some pilots more than others. Therefore, this study also examined …

Post-Tillage Dynamics Of Soil Structural And Hydraulic Properties Induced By Capillary Forces And External Loading, Teamrat Afewerki Ghezzehei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tillage modifies the soil structure to create conditions favorable for plant growth. However, the resulting loose structure is susceptible to collapse by internal capillary forces and external compactive stresses with concurrent changes in soil hydraulic properties. Presently, limited understanding of these complex processes often leads to consideration of the soil plow-layer as a static porous medium. The objective of this dissertation was to develop physically based modeling of soil structural dynamics at the pore scale, based on soil mechanical and rheological properties. The basic geometrical framework of the models was based on regular packing of monosized spherical aggregates forming unit-cells. …

Learning To Move Amid Uncertainty, Robert A. Scheidt, Jonathan B. Dingwell, Ferdinando A. Mussa-Ivaldi

Biomedical Engineering Faculty Research and Publications

We studied how subjects learned to make movements against unpredictable perturbations. Twelve healthy human subjects made goal-directed reaching movements in the horizontal plane while holding the handle of a two-joint robotic manipulator. The robot generated viscous force fields that perturbed the limb perpendicular to the desired direction of movement. The amplitude (but not the direction) of the viscous field varied randomly from trial to trial. Systems identification techniques were employed to characterize how subjects adapted to these random perturbations. Subject performance was quantified primarily using the peak deviation from a straight-line hand path. Subjects adapted their arm movements to the …

Video Partitioning By Temporal Slice Coherency, Chong-Wah Ngo, Ting-Chuen Pong, Roland T. Chin

Research Collection School Of Computing and Information Systems

We present a novel approach for video partitioning by detecting three essential types of camera breaks, namely cuts, wipes, and dissolves. The approach is based on the analysis of temporal slices which are extracted from the video by slicing through the sequence of video frames and collecting temporal signatures. Each of these slices contains both spatial and temporal information from which coherent regions are indicative of uninterrupted video partitions separated by camera breaks. Properties could further be extracted from the slice for both the detection and classification of camera breaks. For example, cut and wipes are detected by color-texture properties, …

Role Of Use Case Diagram In Requirement Analysis, Keng Siau, L. Lee

Research Collection School Of Computing and Information Systems

Since its debut and acceptance as a de facto standard of the object-oriented paradigm, UML has receivedcontroversial reviews. The most controversial diagramming technique in UML is undoubtedly the Use Casediagrams. Some claim that Use Case diagrams do not play a valuable role in requirement analysis. Othersargue that Use Case diagrams captured neither the static nor the dynamic aspects of the systems. The objective of this study is to investigate the role and value of Use Case diagrams in requirement analysis. We will investigate the information content of Use Case diagram and its role in requirement analysis.

Autoconfiguration, Registration And Mobility Management For Pervasive Computing, Archan Misra, Subir Das, Anthony Mcauley, Sajal K. Das

Research Collection School Of Computing and Information Systems

In the vision of pervasive computing, users will exchange information and control their environments from anywhere using various wireline/wireless networks and computing devices. We believe that current protocols, such as DHCP, PPP, and Mobile IP, must be enhanced to support pervasive network access. In particular, this article identifies three fundamental functions: autoconfiguration, registration, and mobility management, that need such enhancements. Realizing that the IP autoconfiguration capabilities must be extended to configure routers and large dynamic networks, we first describe our autoconfiguration solution based on the dynamic configuration and distribution protocol (DCDP). Second, we discuss why providing user-specific services over a …

Was The Path Nephi Saw "Strait And Narrow" Or "Straight And Narrow"?, Noel B. Reynolds, Royal Skousen

Journal of Book of Mormon Studies

The two spellings strait and straight are often considered synonymous; however, they come from different Middle English words and have different meanings. Strait means “narrow” or “tight,” whereas straight means “not crooked.” The difference in these meanings affects the interpretation of the scriptural phrase “strait/straight and narrow path” and others like it. Reynolds and Skousen explore possible meanings that the original Book of Mormon authors may have intended in their use of the two words.

Magnetoacoustic Plasmons In A Bilayer Quasi-Two-Dimensional Spin-Polarized System, D C. Marinescu, I Tifrea

Publications

We investigate the charge and spin response functions of a bilayer quasi-two-dimensional system, spin polarized by a constant magnetic field B ជ . Terms beyond the random-phase approximation, the exchange and correlation interactions, are introduced by using generalized spin-dependent local field factors, G␴ x,c(qជ,␻). The self-consistent magnetic interaction among the electron spins determines the coupling of the charge and the longitudinal spin-density excitations, leading to coupled in-phase and out-of-phase electric and magnetic modes. We find that the lowest frequency belongs to an acoustic mode, that represents the out-of-phase oscillation of the longitudinal magnetizations in the two layers. This collective excitation …

The Scientific Foundations Of Habitat Conservation Plans: A Quantitative Assessment, Elaine K. Harding, Elizabeth E. Crone, Bret D. Elderd, Jonathan M. Hoekstra, Alexa J. Mckerrow, John D. Perrine, Jim Regetz, Leslie J. Rissler, Amanda G. Stanley, Eric L. Walters

Faculty Publications

The number of habitat conservation plans (HCP) has risen dramatically since the first plan was written over 18 years ago. Until recently, no studies have quantitatively investigated the scientific foundations underlying these documents. As part of a larger study of HCPs, we examined 43 plans primarily to assess the availability and use of scientific data and secondarily to determine the extent of involvement by, and influence of independent scientists within the process. Specifically, our analysis focused on five key steps taken when an HCP is developed: assessing status of a species, determining take, predicting the project effects, mitigating for those …

More Light On Who Wrote The Title Page, Clyde J. Williams

Journal of Book of Mormon Studies

The title page of the Book of Mormon was most likely written by Moroni, but in recent years scholars have suggested that Mormon, Moroni’s father, may have written the first six lines of the title page, with Moroni writing the rest. However, a more in-depth analysis of the text on that page and the specific language that is used provides evidence supporting the notion that the title page was, in fact, written solely by Moroni.

Serpent Symbols And Salvation In The Ancient Near East And The Book Of Mormon, Andrew C. Skinner

Journal of Book of Mormon Studies

The serpent is often used to represent one of two things: Christ or Satan. This article synthesizes evidence from Egypt, Mesopotamia, Phoenicia, Greece, and Jerusalem to explain the reason for this duality. Many scholars suggest that the symbol of the serpent was used anciently to represent Jesus Christ but that Satan distorted the symbol, thereby creating this paradox. The dual nature of the serpent is incorporated into the Old Testament, the New Testament, and the Book of Mormon.

Reproductive Constraints And The Evolution Of Life Histories With Indeterminate Growth, Eric Charnov, Thomas Turner, Kirk Winemiller

Biology Faculty & Staff Publications

This article develops a new evolutionary model for life histories by combining a new production-growth model with some general, yet specific, constraints on reproductive allocation, and by allowing natural selection to adjust the age of first breeding and the metabolic/productive capacity of cells. The optimal life histories correctly predict the numeric value of dimensionless numbers that combine maturation age (size), mortality, and reproductive allocation. The life-history prediction also yields a new lifetime growth model for body mass under indeterminate growth and predicts that the fastest growth rate will be near the size at first reproduction. Table 1 is a glossary …

Quasi-Su(3) Truncation Scheme For Even-Even Sd-Shell Nuclei, C. E. Vargas, J. G. Hirsch, J. P. Draayer

Faculty Publications

The quasi-SU(3) symmetry was uncovered in full pf and sdg shell-model calculations for both even-even and odd-even nuclei. It manifests itself through a dominance of single-particle and quadrupole-quadrupole terms in a Hamiltonian used to describe well-deformed nuclei. A practical consequence of the quasi-SU(3) symmetry is an efficient basis truncation scheme. In [C.E. Vargas et al., Phys. Rev. C 58 (1998) 1488] it is shown that when this type of Hamiltonian is diagonalized in an SU(3) basis, only a few irreducible representations (irreps) of SU(3) are needed to describe the yrast band, the leading S=0 irrep augmented with the leading S=1 …
