description: The growth of supermassive black holes (SMBHs) through merging has long been predicted but its detection remains elusive. However, a promising target has been discovered in the Seyfert-1 galaxy J1430+2303. If a binary system truly lies at the center of J1430+2303, the usual symmetry expected from pole-on views in active galactic nuclei (AGNs) responsible for the observed low ($\le$ 1\%) optical linear polarization in the continuum of these objects is expected to be broken. This should lead to higher-than-usual polarization degrees, together with time-dependent variations of the polarization signal. We used the specialized photopolarimeters RoboPol mounted on the 1.3m telescope at the Skinakas Observatory and the Alhambra Faint Object Spectrograph and Camera (ALFOSC) mounted on the 2.56m Nordic Optical Telescope (NOT) at the "Roque de los Muchachos" Observatory to measure the B-, V-, R-, and I-band polarization of J1430+2303. Observations were complemented using the FORS2 spectropolarimeter mounted on the VLT to acquire 3500 -- 8650 Angs polarized spectra. We compared our set of observations to Monte Carlo radiative-transfer predictions to look for the presence of a SMBH binary. The observed linear continuum polarization of J1430+2303 in the V and R bands is $\sim$ 0.4\% with an associated polarization angle of slightly larger than 0$^\circ$. We detected no significant changes in polarization or photometry between May, June, and July of 2022. In addition, there is no significant difference between the polarization of H$α$ and the polarization of the continuum. A single SMBH at the center of an AGN model is able to reproduce the observed spectrum and polarization, while the binary hypothesis is rejected with a probability of $\sim$85\%.

description: Controlling and engineering continuous spectral modes of entangled photons represents one of the promising approaches toward secure quantum communications. By using the telecom bandwidth generated from a cascade-emitted biphoton in atomic ensembles, a fiber-based long-distance quantum communication can be feasible owing to its low transmission loss. With multiplexed photon pairs, we propose to implement a nonorthogonal coding scheme in their spectral modes and present an architecture of multiple channels enabling a high-capacity transfer of codewords. Using the measures of the second-order correlations and associated visibility and contrast, we further quantify the performance of the proposed nonorthogonal coding scheme. Our results demonstrate the capability to encode and decode quantum information beyond the orthogonal coding scheme. The proposed scheme here can be applicable to a large-scale and multiuser quantum communication and pave the way toward an efficient and functional quantum information processing.

title: Computer Simulation of Urban Runoff Characteristics Within Salt Lake County
Creators: name: Parnell, Robert Newman
Publisher: name: Utah State University
Year: 1971

description: A hybrid computer program is developed to simulate the outflow hydrographs of two urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a checkpoint for comparing the observed and the simulated final outflow hydrographs.
The outflow hydrographs for each subzone of the two watersheds were obtained by abstracting interception, infiltration and depression storage from each subzone hyetograph. The outflow of the subzones were routed to the Jordan River, the final outflow point of the two watersheds. The final hydrographs of the watersheds were combined and compared with the gaged flow.
The uniquenesses of this systems model are the flexibility in varying hyetographs, variable loss rates, combination of subzone hydrographs, and the combination of watershed hydrographs. Subzone hydrographs can also be plotted for visual inspection as well as obtaining numerical values. With a variety of input and output data, designers and planners can visually perceive urban runoff characteristics. The systems model should be a tool used by those interested in urban runoff characteristics.

Creators: name: Olsen, Eldon Gene
Publisher: name: Utah State University
Year: 1971

description: Trends in Utah's agriculture and some factors influencing farmer's decisions concerning eight crops produced on irrigated lands in Utah were studied. Trend lines were calculated and compared with statistics of acreages and yields. Simple and multiple regression tests were made.
An increasing number of Utah farmers have taken off-farm employment and operate their farms on a part-time basis. Forage and grain crops both adapt readily to part0time farm operations and these crops do not entail the degree of risk involved in the production of most cash crops. Variety improvements have caused some shifting to wheat production. Product prices, costs, weather, government programs, and labor problems were also found to be important factors influencing farmers decisions.
Comparison of modified black-body fits for the estimation of dust optical depths in interstellar clouds

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: When dust far-infrared spectral energy distributions (SEDs) are fitted with a single modified black body (MBB), the optical depths tend to be underestimated. This is caused by temperature variations, and fits with several temperature components could lead to smaller errors. We want to quantify the performance of the standard model of a single MBB in comparison with some multi-component models. We are interested in both the accuracy and computational cost. We examine some cloud models relevant for interstellar medium studies. Synthetic spectra are fitted with a single MBB, a sum of several MBBs, and a sum of fixed spectral templates, but keeping the dust opacity spectral index fixed. When observations are used at their native resolution, the beam convolution becomes part of the fitting procedure. This increases the computational cost, but the analysis of large maps is still feasible with direct optimisation or even with Markov chain Monte Carlo methods. Compared to the single MBB fits, multi-component models can show significantly smaller systematic errors, at the cost of more statistical noise. The $χ^2$ values of the fits are not a good indicator of the accuracy of the $τ$ estimates, due to the potentially dominant role of the model errors. The single-MBB model also remains a valid alternative if combined with empirical corrections to reduce its bias. It is technically feasible to fit multi-component models to maps of millions of pixels. However, the SED model and the priors need to be selected carefully, and the model errors can only be estimated by comparing alternative models.

description: This research project studied causes and possible remediation inspection strategies to prevent failures for anhydrous ammonia (NH3) nurse tanks. Nurse tanks are steel tanks used to transport NH3 locally over public roadways and farm fields. Many of the reportedly 200,000 nurse tanks in use in the United States are 3 to 5 decades old. Several tank failures have occurred in recent years. Nurse tank failures can injure workers and bystanders by way of chemical burns, frostbite, suffocation, and physical injuries caused by the catastrophic force of rupture. This research study addressed this problem by: surveying the technical literature on nurse tank properties and case studies of tank failures; examination of 20 used nurse tanks by metallography, glow discharge spectroscopy, neutron diffraction analysis of residual stresses, ultrasound, and fluorescent dye penetrant examination for cracks. It exposed 56 specimens of the commonly used tank steel, stressed in tension, while either immersed in liquid NH3 or exposed to pure NH3 vapor, for 7 months to study the initiation and growth of stress corrosion cracks. This research further confirms that stress corrosion cracking is the greatest threat to nurse tank integrity. Recommendations for best inspection practices are presented on how to reduce the risks associated with nurse tank failures.

description: A new determination of the temperature of the intergalactic medium over $3.9 \leq z \leq 4.3$ is presented. We applied the curvature method on a sample of 10 high resolution quasar spectra from the Ultraviolet and Visual Echelle Spectrograph on the VLT/ESO. We measured the temperature at mean density by determining the temperature at the characteristic overdensity, which is tight function of the absolute curvature irrespective of $γ$. Under the assumption of fiducial value of $γ= 1.4$, we determined the values of temperatures at mean density $T_{0} = 7893^{+1417}_{-1226}$ K and $T_{0} = 8153^{+1224}_{-993}$ K for redshift range of $3.9 \leq z \leq 4.1$ and $4.1 \leq z \leq 4.3$, respectively. Even though the results show no strong temperature evolution over the studied redshift range, our measurements are consistent with an intergalactic medium thermal history that includes a contribution from He II reionization.

The effects of social experience on play and agonistic behavior in the golden hamster and the Mongolian gerbil
Creators: name: Skirrow, Margaret Helen Wort
Publisher: name: University of British Columbia
Year: 2011

description: To determine the effects of different social conditions on play and agonistic behaviour, 25-day old golden hamsters and Mongolian gerbils were divided into four groups which differed with respect to social experience after weaning. Every day, from 26 to 61 days of age, the young hamsters were observed for numbers and durations of fight-type interactions in a 15-minute period. Every third or sixth day from 27 to 60 days of age, the gerbils were similarly tested. Seven to 14 percent of play fights between hamsters involved more than two animals simultaneously. Communally reared hamsters mixed with strangers played with strangers 71 percent of the time, while 90 percent of real fights involved strangers. Neither of these measures involved the effects of early social experience. Isolation causes earlier cessation of play and earlier onset of real fights in golden hamsters. Isolation also leads to a significant increase in the amount of play and real fighting in these animals. Gerbils raised in isolation with a toy show significantly more play than do gerbils reared under different social conditions. Gerbils reared communally with the mother fight significantly more with strangers than they do with familar animals, and fight significantly more than do animals reared communally with siblings, or in isolation with or without a ping pong ball.

description: We review our recent work leading to steady-state solutions of the semiclassical (Maxwell-Bloch) equations of a laser. These are coupled non-linear partial differential equations in space and time which have previously been solved either by fully time-dependent numerical simulations or by using major approximations which neglect non-linear modal interactions and/or the openness of the laser system. We have found a time-independent technique for determining these stationary solutions which can treat lasers of arbitrary complexity and degree of openness. Our method has been shown to agree with time-dependent numerical solutions to high accuracy and has been applied to find the electric field patterns (lasing modes) of random lasers, which lack a laser cavity and are so strongly damped that the linear system has no detectable resonances. Our work provides a link between an important non-linear wave system and the field of quantum/wave chaos in linear systems.

Contamination in TESS light curves: The case of the Fast Yellow Pulsating Supergiants

description: Given its large plate scale of 21" / pixel, analyses of data from the TESS space telescope must be wary of source confusion from blended light curves, which creates the potential to attribute observed photometric variability to the wrong astrophysical source. We explore the impact of light curve contamination on the detection of fast yellow pulsating supergiant (FYPS) stars as a case study to demonstrate the importance of confirming the source of detected signals in the TESS pixel data. While some of the FYPS signals have already been attributed to contamination from nearby eclipsing binaries, others are suggested to be intrinsic to the supergiant stars. In this work, we carry out a detailed analysis of the TESS pixel data to fit the source locations of the dominant signals reported for 17 FYPS stars with the Python package TESS_localize. We are able to reproduce the detections of these signals for 14 of these sources, obtaining consistent source locations for four. Three of these originate from contaminants, while the signal reported for BZ Tuc is likely a spurious frequency introduced to the light curve of this 127-day Cepheid by the data processing pipeline. Other signals are not significant enough to be localized with our methods, or have long periods that are difficult to analyze given other TESS systematics. Since no localizable signals hold up as intrinsic pulsation frequencies of the supergiant targets, we argue that unambiguous detection of pulsational variability should be obtained before FYPS are considered a new class of pulsator.

description: We present exact multi-parameter families of soliton solutions for two- and three-component Manakov equations in the \emph{defocusing} regime. Existence diagrams for such solutions in the space of parameters are presented. Fundamental soliton solutions exist only in finite areas on the plane of parameters. Within these areas, the solutions demonstrate rich spatio-temporal dynamics. The complexity increases in the case of 3-component solutions. The fundamental solutions are dark solitons with complex oscillating patterns in the individual wave components. At the boundaries of existence, the solutions are transformed into plain (non-oscillating) vector dark solitons. The superposition of two dark solitons in the solution adds more frequencies in the patterns of oscillating dynamics. These solutions admit degeneracy when the eigenvalues of fundamental solitons in the superposition coincide.

Minimal unitary representation of SU(2,2) and its deformations as massless conformal fields and their supersymmetric extensions

description: We study the minimal unitary representation (minrep) of SO(4,2) over an Hilbert space of functions of three variables, obtained by quantizing its quasiconformal action on a five dimensional space. The minrep of SO(4,2), which coincides with the minrep of SU(2,2) similarly constructed, corresponds to a massless conformal scalar in four spacetime dimensions. There exists a one-parameter family of deformations of the minrep of SU(2,2). For positive (negative) integer values of the deformation parameter ζone obtains positive energy unitary irreducible representations corresponding to massless conformal fields transforming in (0,ζ/2) ((-ζ/2,0)) representation of the SL(2,C) subgroup. We construct the supersymmetric extensions of the minrep of SU(2,2) and its deformations to those of SU(2,2|N). The minimal unitary supermultiplet of SU(2,2|4), in the undeformed case, simply corresponds to the massless N=4 Yang-Mills supermultiplet in four dimensions. For each given non-zero integer value of ζ, one obtains a unique supermultiplet of massless conformal fields of higher spin. For SU(2,2|4) these supermultiplets are simply the doubleton supermultiplets studied in arXiv:hep-th/9806042.

title: Estimating Agricultural Production Functions from Experimental Data for Different Crops in Relation to Irrigation, Fertilization and Soil Management in Northern Utah
Creators: name: Nathan, Subramaniuam Swami
Publisher: name: Utah State University
Year: 1971

description: Estimates of agricultural production functions from experimental data for four different crops in relation to six variable inputs are calculated by this study. There are four basic sections in the study. The first section covers the review of production function concepts and the procedures and problems that specifically pertain to this study. Also the importance of joint economic-agronomic research efforts, methodologies and applications of agricultural production functions are cited.
The second section includes the presentation data and postulated functional relationships in estimating production functions. Model building programs are used in developing three dimensional figures, which aid in the selection of the appropriate model. A multiple regression model using linear, non-linear and interaction terms is employed in deriving three production function for each crop. The problem of selecting a "best" model from the above three models is solved on the basis of economic theory, observed biologic physical production process, projected three dimensional production surfaces and statistical analyses. The polynomial form was selected as the "best" model for each crop.
The third section of this study analyzes the results and the economic implications. Optimal rates of input use are determined. Qualification of these results are required because of the non significant statistical relationships including the F values of the regression coefficients and relatively low coefficient of determination (R2), and, also, because some optimal inputs values did not seem reasonable relative to observed rates. Further statistical analyses are carried out to determine the confidence interval for each input's marginal productivity and this results in unbounded solutions. As an alternative, the above confidence interval problem is rephrased as a system of equalities and solved simultaneously to obtain optimal input levels at the marginal productivities maximum and minimum values and these estimates are shown not to be confidence intervals.
Finally, in the fourth section of this study, summary and conclusions are given. Also, limitation and recommendations to the study are discussed.

Year: 1971

description: The objectives of this study were first, to examine the attitudes of L.D.S. (members of the Church of Jesus Christ of Latter-Day Saints; also commonly known as the Mormon Church) senior citizens living within the city limits of Logan, Utah regarding certain of their personal adjustments during old age (a personal adjustment score was derived from a scale developed by Cavan, Burgess, Havighurst and Goldhammer, 1949); and second, to determine whether selected variables were related to these attitudes toward personal adjustment. The variables examined in determining this relationship were chronological age, sex, marital status, the individual's definition of present health, length of time in current housing and the degree of social involvement.
Each of the following four variables proved to have a positive, significant association with the personal adjustment attitudinal score--chronological age, marital status, the individual's definition of present health and degree of social involvement. The two remaining variables are sex and length of time in current housing. Neither of these latter two was found to be significantly associated with the personal adjustment score

title: Economic Rent Values for Pheasant Hunting in Utah
Creators: name: V., Braulio Rodriguez
Publisher: name: Utah State University
Year: 1971

description: A conceptual model relating recreation resource values to the concept of economic rent was developed. The model argues that recreation sites possess both quality and location characteristics which serve as rent producing agents. Sites of better quality extract economic rents relative to those of lesser quality while those located most advantageously to user origins earn location rents relative to those more distantly located. The economic rent values are expressed by the differential use costs and recreationist activity associated with individual site usage.
A methodological procedure was developed which generates estimates of total rent values for a given site. The procedure permits identification of rent values separately related to site location and quality.
Application of the model was made by estimating recreation values for pheasant hunting in Utah using 1966 data. These data were collected by mail survey from hunters following the 1966 hunting season. Approximately 1,025 questionnaires were used in the analysis.
The total rent value estimated from the model was approximately 5.8 million dollars. About 83 percent of the total was attributed to site quality and 17 percent to location. No attempt was made to analyze the variables related to quality. In only three counties, Juab, Millard, and Utah, were location values found to exceed those resulting from quality. Total rent values were highest for Weber, Cache, Box Elder and Davis counties.

description: We report VLA B-configuration observations of the HI 21 cm line on the close disk galaxy pair NGC 5595 and NGC 5597. At the angular resolution of the observations, $\sim7.1'' \times 4.2''$, while most of the HI 21 cm in NGC 5595 and in NGC 5597 has the same extent as the optical disk, we have detected for the first time extended structures (streamers) to the north-east (NE), and south-west (SW) of NGC 5595 with no counterparts in blue, red optical (continuum), 20 cm radio continuum, or H$α$ spectral-line emission. One structure is extended by $\sim 45''$ to the NE with blue-shifted velocities, and the other by $\sim 20''$ to the SW with red-shifted velocities with respect to the systemic velocity. No HI 21 cm emission is detected from the innermost central (nuclear) regions of either galaxy. Lower angular resolution HI 21 cm imaging indicates the non-existence of any intergalactic HI 21 cm gas as tails or bridges between the two galaxies. Our new 20 cm radio continuum emission image of NGC 5597 shows a strong unresolved elongated structure at the central region, in the north-east south-west direction, very similar to the spatial location of the innermost H$α$ spectral line emission. There is no 20 cm continuum emission from its north spiral arm.

description: Relying on precise observations for the CPD-54 810 binary system, we investigate the robustness of the estimated age and convective core overshooting for a system with both stars on the main sequence (MS). [...] We adopt the SCEPtER pipeline, based on grids of stellar models computed for a different initial chemical composition and convective core overshooting efficiency. The base fit suggests a common age of $3.02 \pm 0.15$ Gyr, in agreement with recent literature. This estimated convective core overshooting parameter is $β= 0.09 \pm 0.01$, with a corresponding convective core mass $M_c = 0.059^{+0.017}_{-0.021}$ $M_{\odot}$. The robustness of these estimates were tested assuming a narrow constraint on the helium-to-metal enrichment ratio. The chemical solution of the system changes, but the age and the overshooting parameter are almost unchanged ($3.08^{+0.17}_{-0.14}$ Gyr and $0.09 \pm 0.01$). In a further test, we halved the uncertainty as to the effective temperature of both stars and again the estimated parameter shows only small variations ($3.02 \pm 0.12$ Gyr and $0.09 \pm 0.01$). This low variability suggests that the age of the system with both stars in the MS can be reliably estimated at a 5\% level, but it also indicates that the power of the investigation is probably low. [...] Despite the great increase in the observational constraints' precision, the results support the conclusions of previous theoretical works on the stellar parameter calibration with double MS star binary systems.

By "collision" we mean a strong (possibly discontinuous) change in the system. For such models we prove uniqueness of the SRB measure and exponential space-time decay of correlations.
title: Changing Patterns of Juvenile Justice in District One Juvenile Court, Utah, as Affected by the 1967 U.S. Supreme Court Decision on Gault
Creators: name: Mickelson, Ruth V.
Publisher: name: Utah State University
Year: 1970

description: A determination was made of the degree to which the four requirements of Gault were met in District I of the Utah Juvenile Court between July l, 1967 and June 30, 1969. The requirements handed down in 1967 by the U. S. Supreme Court were as follows: (a) guarantee to the right of notice given to the juvenile himself and to his parents; (b) right to counsel , representation by counsel in juvenile delinquency proceedings; (c) right to confrontation and cross-examination by prosecuting witness; and (d) privilege against self- incrimination in juvenile delinquency proceedings.
Observable procedures indicate that sustained effort is being made by District I, Utah, toward affording protection of basic legal rights to juvenile court clients and their families. However, the juvenile court records, as the source of information for this study, show the four requirements of Gault as being met only in part during the period of time specified. It was also found that, with only two changes, the Utah Juvenile Court Act of 1965 would have already been fulfilling, in Utah, the requirements provided by the subsequent 1967 U.S. Supreme Court decision on Gault. These two recommended changes were, first, a provision requiring that it be recorded whether or not the child was notified of his rights; and second, that a provision be added to record the name of the complainant, his presence, and if his testimony was used during the proceeding.
Using a one-dimensional finite-element approximation of Webster's horn equation to estimate individual ear canal acoustic transfer from input impedances

description: In many applications, knowledge of the sound pressure transfer to the eardrum is important. The transfer is highly influenced by the shape of the ear canal and its acoustic properties, such as the acoustic impedance at the eardrum. Invasive procedures to measure the sound pressure at the eardrum are usually elaborate or costly. In this work, we propose a numerical method to estimate the transfer impedance at the eardrum given only input impedance measurements at the ear canal entrance by using one-dimensional first-order finite elements and Nelder-Mead optimization algorithm. Estimations on the area function of the ear canal and the acoustic impedance at the eardrum are achieved. Results are validated through numerical simulations on ten different ear canal geometries and three different acoustic impedances at the eardrum using synthetically generated data from three-dimensional finite element simulations.

title: American History and Teaching Critical Thinking
Creators: name: Miller, James M.
Publisher: name: Utah State University
Year: 1970

description: The effect of teaching critical thinking as part of a continuous progress packet in American history was studied at Cedar High School during the 1969-70 school year. An experimental group using the critical thinking packet was compared with a control group that used a continuous progress packet that taught only American history.
The dependent variables for the study were the STEP (Sequential Test of Educational Progress), Social Studies portion, and the Watson-Glaser Critical Thinking Appraisal. No statistically significant differences were found between the groups in either American history or critical thinking.
Differences in critical thinking ability, though not significant statistically, seemed to indicate the desirability of further research in this area. It was also recommended, as a result of this study, that further research be conducted to develop and evaluate new methods of assessing student competence in seminar situations.
Josephson Diode Effect Induced by Valley Polarization in Twisted Bilayer Graphene

description: Recently, the Josephson diode effect (JDE), in which the superconducting critical current magnitudes differ when the currents flow in opposite directions, has attracted great interest. In particular, it was demonstrated that gate-defined Josephson junctions based on magic-angle twisted bilayer graphene showed a strong nonreciprocal effect when the weak-link region is gated to a correlated insulating state at half-filling (two holes per moiré cell). However, the mechanism behind such a phenomenon is not yet understood. In this work, we show that the interaction-driven valley polarization, together with the trigonal warping of the Fermi surface, induce the JDE. The valley polarization, which lifts the degeneracy of the states in the two valleys, induces a relative phase difference between the first and the second harmonics of supercurrent and results in the JDE. We further show that the nontrivial current phase relation, which is responsible for the JDE, also generates the asymmetric Shapiro steps.

description: We calculate the dissipative dynamics of two-qubit quantum discord under Markovian environments. We analyze various dissipative channels such as dephasing, depolarizing, and generalized amplitude damping, assuming independent perturbation, in which each qubit is coupled to its own channel. Choosing initial conditions that manifest the so-called sudden death of entanglement, we compare the dynamics of entanglement with that of quantum discord. We show that in all cases where entanglement suddenly disappears, quantum discord vanishes only in the asymptotic limit, behaving similarly to individual decoherence of the qubits, even at finite temperatures. Hence, quantum discord is more robust than the entanglement against to decoherence so that quantum algorithms based only on quantum discord correlations may be more robust than those based on entanglement.

The effect of intermittent exercise on carbohydrate metabolism in rainbow trout (Salmo gairdneri)
Creators: name: Stevens, Ernest Donald
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to examine the effects of exercise of short duration, and the effects of re-exercise on carbohydrate metabolism. I feel that the levels of severe exercise studied approximate the levels of severe exercise which a rainbow trout probably experiences in its natural environment. The level of blood lactate, blood hemoglobin, muscle lactate, muscle glycogen, and liver glycogen were determined in unanesthetized, intact, one and one-half year old rainbow trout acclimated to 10.5°C. Samples were taken immediately after exercise of 3 seconds to 5 minutes, after recovery of 3 minutes to 60 minutes, and after re-exercise of 3 seconds to 5 minutes. The results indicate that exercise of even the shortest duration studied causes an immediate increase in the level of blood lactate, muscle lactate, and blood hemoglobin. Exercise also causes an immediate decrease in muscle glycogen, but does not cause a change in the level of liver glycogen. Changes during the 60 minute recovery period are slight. In general, the effects of re-exercise after a 60 minute recovery period are additive. A correlation analysis between muscle glycogen and muscle lactate indicates that there is a source of muscle lactate other than muscle glycogen at exercise levels of long duration. The source of this muscle lactate does not appear to come from liver glycogen. The energy may be supplied by catabolism of protein or lipid, or by absorption of foodstuffs from the gut. This study provides evidence that rainbow trout are not well adapted for recovery from severe exercise of short duration.

Year: 1970

description: This study was an attempt to establish and compare prediction equations for determining a minimum GPA of 2. 00 in the Applied Arts programs at Dixie College. It also attempted to compare the derived predict ion equations used to determine mini mum GPA 1 s in both the Academic Arts and Applied Arts Divisions. The study compared the derived prediction equations used to determine minimum GPA's for each vocational program in the Applied Arts Division. The study attempted to determine and compare t he most reliable predictor in the Academic Arts Division, total Applied Arts Division, and each vocational program in the Applied Arts Division.
In conclusion, the thesis illustrates what percent of the total variation of GPA could be accounted for by the derived prediction equations in the Academic Arts Division, total Applied Arts Division, and in each vocational program in the Applied Arts Division. It also determined that the ACT Social Science subtest score proved to be the best single predictor for both the Academic Arts and Applied Arts Divisions at Dixie College as well as for the vocational programs of Architectural Drafting and Airline Stewardess. The ACT Composite score proved to be the best single predictor in the vocational programs of Auto Mechanics, Electronics, and Business Education at Dixie College.
