title: Inhibition of Synaptosomal Biogenic Amine Transport by a Diverse Group of Neurotoxic Chemicals
Creators: name: Bracken, William M.
Publisher: name: Utah State University
Year: 1980

description: Synaptosomal membrane functions were monitored, after in vitro exposure to select environmental pollutants, in synaptosomal preparations originating from rat cerebral cortices. The uptake of NE and 5HT into the synaptosomes was monitored as was the K+-dependent phosphate activity of the membrane. CH3HgCl, Hg(NO3)2, CdCl2, diisopropylfluorophosphate (DFP), paraoxon, acrylamide and Kepone were the test chemicals whose effects were studied.
CH3HgCl, Hg(NO3)2 and Kepone had the greatest inhibitory effects on NE and 5HT uptake. The concentrations producing 50 percent inhibition (IC50) were 1.4x10-4, 4.0x10-4, and 9.4x10-5 M, respectively, for NE uptake while the IC50's for 5HT uptake were 1.9x10-4, 6.0x10-4, and 3.3x10-4 M, respectively. Maximal inhibition was 60-100 percent at 10-3 M while the effective concentration range was between 10-4-10-3 M. The remaining test compounds produced no significant inhibition at concentrations up to 10-3 M.
K+-dependent phosphatase was strongly inhibited by CH3HgCl, Hg(NO3)2, CdCl2, and Kepone with IC50's of 1.5x10-6, 0.032x10-6, 1.5x10-6, and 13.0x10-6 M, respectively. The effective inhibitory concentrations for these chemicals ranged from 10-7-10-3 M and suggested a specific high affinity inhibition. DFP, paraoxon and acrylamide did not produce a significant inhibition at concentrations between 10-5-10-3 M.
A correlation of the phosphatase and monoamide uptake inhibitions, in search of a cause-effect relationship, was not suggested from the data. However, the low affinity inhibition (IC50 greater than 10-5 M) of the NE and 5HT uptake by CH3HgCl, Hg(NO3)2 and Kepone, along with the general shape of the dose-response curve is suggestive of an all-or-none inhibition. The apparent high affinity inhibition (IC50 less than 10-5 M) of the phosphatase demonstrates the specific influences of these compounds can have on enzymatic processes. Such enzymatic inhibition could be of critical importance if these neurotoxicants were able to penetrate the synaptosomal or even neuronal membrane and gain access to the metabolic and synthetic machinery.

title: Alterations in Rat Brain Norepinephrine and Dopamine Levels and Synthesis Rates in Response to Five Neurotoxic Chemicals: Acrylamide, 2,5-hexanedione, Tri-o-tolyl Phosphate, Leptophos, and Methyl Mercuric Chloride

description: Acrylamide, 2,5-hexanedione, Tri-o-tolyl phosphate and leptophos belong to three fundamentally different chemical classes but all four chemicals cause central-peripheral distal axonopathy. Some of these compounds have been shown to alter brain steady state levels of neurotransmitters or to inhibit the activities of adenosine triphosphatases which are involved in the uptake and storage of biogenic amines. Tests were performed to determine alterations in steady state levels of rat brain norepinephrine and dopamine in response to doses of the above chemicals and of the central nervous system toxin, methyl mercuric chloride sufficient to cause ataxia. Catecholamine synthesis rate constant estimations were performed. Specific activities of tyrosine in brains of control and treatment groups following intravenous injection of labelled tyrosine were compared to determine if passage of tyrosine across the blood-brain barrier were affected by treatments. Levels of the dopamine metabolite, dihydroxyphenylacetic acid were assayed in all cases. Levels of the norepinephrine metabolite, 3-methoxy-4-hydroxymethylethyleneglycol sulfate, were assayed in response to acrylamide administration. Animal weights were recorded at the beginning and end of the treatment period. Rats treated with a cumulative dose of 250 mg/kg acrylamide had significantly lower norepinephrine levels than controls. 2,5-hexanedione administration significantly increased the dopamine synthesis rate constant at a cumulative dose of 210 mg/kg. Cumulative doses of 700 and 2100 mg/kg also appeared to elevate norepinephrine and dopamine synthesis rate constants, but values were not statistically significant. Leptophos caused a slight but significant increase in dopamine levels in rats administered a cumulative dose of 75 mg/kg. Methyl mercuric chloride caused variable effects to norephinephrine synthesis rate and lowered dopamine synthesis rate constant at cumulative doses of 5 to 50 mg/kg. No other alterations were seen in levels of catecholamines or of their metabolites, nor in synthesis rate constants of the catecholamines in response to administration of the five neurotoxic compounds. No evidence of altered blood-brain transport of tyrosine was observed at any level of neurotoxins administered. Rats given the highest cumulative doses of all neurotoxins except tri-o-tolyl phosphate gained significantly less weight than control animals. It was concluded that the four compounds which cause delayed distal neurotoxicity do not alter levels of turnover rates of brain catecholamines in a consistent manner.

description: We present a 350-year hydroclimatic year (HY) index for northern Vietnam derived from three discrete seasonal reconstructions from tree rings: an index of autumn rainfall from the earlywood widths of Chinese Douglas fir (Pseudotsuga sinensis), the first such record from this species, and two nearby published Palmer Drought Severity Index (PDSI) reconstructions from cypress (Fokienia hodginsii) tree rings for spring and summer, respectively. Autumn rainfall over the study region constitutes only around 9% of the annual total, but its variability is strongly linked to the strength of the atmospheric gradient over Asia during the transition from the boreal summer to winter monsoons. Deficit or surplus of autumn rainfall enhances or mitigates, respectively, the impact of the annual winter dry season on trees growing on porous karst hillsides. The most protracted HY drought (dry across all seasons) occurred at the turn of the twentieth century at a time of relative quiet, but a mid-to-late eighteenth century multi-year HY drought coincided with a period of great societal turmoil across mainland Southeast Asia and the Tay Son Rebellion in northern Vietnam. A mid-nineteenth century uprising accompanied by a smallpox epidemic, crop failure and famine, occurred during the worst autumn drought of the past two and a half centuries but only moderate drought in spring and summer. The “Great Vietnamese Famine” of the mid-twentieth century was dry only in autumn, with a wet spring and an average summer.
title: An Analysis of the Production and Marketing of Pineapples from the Soesdyke/Linden Land Development Project in Guyana
Creators: name: Hunte, Cyril Kenrick
Publisher: name: Utah State University
Year: 1981

description: The purpose of this study was to examine the production and marketing behavior of pineapple farmers in the Soesdyke/Linden Land Development Project in Guyana. A random sample was drawn from eight locations in the project and 51 personal interviews were conducted with pineapple farmers. Emphasis was placed on ascertaining the current levels and use of basic inputs in the production process as well as determining the profitability of pineapple production. The nature an extent of the infra-structure provided by government to the project were also examined. Attention was given to the work done on providing roads and transportation as well as government funding for the project. The resource endowments of the Soesdyke/Linden Region were described in relation to the production of pineapples form the Soesdyke/Linden Development (S.L.L.D.P.). The outcome of the study showed that although pineapple production was still a profitable venture many resources were under utilized. there was a scope for employing better management and production techniques. The Infra-structure provided by government was incomplete. There was a lack of transportation facilities and a poor distribution system for pineapples, and operational and pricing efficiency were still to be attained in the processing sector of the marketing channel.
title: Single Mothers: The Impact of Work on Home and the Impact of Home on Work
Creators: name: Rasmussen Robbins, Lenore I.
Publisher: name: Utah State University
Year: 1993

description: The purpose of this study was to assess the relationships between family/home satisfaction and job satisfaction of single working mothers with at least one child under the age of 18 living at home. The principal objectives were to identify the stressful situations in the lives of working single mothers and the factors that contributed to home satisfaction and work satisfaction. Data were gathered by survey questionnaire from single working mothers presently living in Iron County, Utah. Factor analysis was used to reduce data into home satisfaction and work satisfaction factors that were analyzed by multiple regression to determine the variance they explain. Stepwise multiple regression identified 1) family interaction, 2) income, housing, and health, and 3) family diet and money management as the home and family factors that predict satisfaction with home life. This multiple regression identified 1) family interaction, 2) time commitments, 3) income, housing, and health, 4) family and community support, and 5) family diet and money management as the home and family factors that can predict satisfaction with work. The work factors that can predict home life satisfaction were found to be 1) work schedule, 2) work environment, and 3 ) salary and advancement. Work factors that predict satisfaction with work were 1) breaks and control, 2) schedule and salary, and 3) commuting and friends at work. Working single mothers identified single parenting, financial problems, major changes in work or family, and problems with children as the situations causing stress in their lives. A statistically significant relationship was found with income and 1) education, 2) perception of enough income, 3) satisfaction with home life, and 4) work satisfaction.

description: Objective: Individuals with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for poor school performance, and pharmacological treatment of ADHD may have beneficial effects on school performance. Conclusions from previous research have been limited by small sample sizes, outcome measures, and treatment follow-up. The current study analyzed school performance in students with ADHD compared to students without ADHD, and the association between pharmacological treatment of ADHD and school performance. Method: A linkage of Swedish national registers covering 657,720 students graduating from year 9 of compulsory school provided measures of school performance, electronically recorded dispensations of ADHD medication, and potentially confounding background factors such as parental socioeconomic status. Primary measures of school performance included student eligibility to upper secondary school and grade point sum. Results: ADHD was associated with substantially lower school performance independent of socioeconomic background factors. Treatment with ADHD medication for 3 months was positively associated with all primary outcomes, including a decreased risk of no eligibility to upper secondary school, odds ratio = 0.80, 95% confidence interval (CI) = 0.76−0.84, and a higher grade point sum (range, 0.0−320.0) of 9.35 points, 95% CI = 7.88−10.82; standardized coefficient = 0.20. Conclusion: ADHD has a substantial negative impact on school performance, whereas pharmacological treatment for ADHD is associated with higher levels in several measures of school performance. Our findings emphasize the importance of detection and treatment of ADHD at an early stage to reduce the negative impact on school performance.
Single particle in quantum gravity and Braunstein-Ghosh-Severini entropy of a spin network

description: Passerini and Severini have recently shown that the Braunstein-Ghosh-Severini (BGS) entropy S(Gamma) = -Tr[rho(Gamma) log rho(Gamma)] of a certain density matrix rho(Gamma) naturally associated to a graph Gamma, is maximized, among all graphs with a fixed number of links and nodes, by regular graphs. We ask if this result can play a role in quantum gravity, and be related to the apparent regularity of the physical geometry of space. We show that in Loop Quantum Gravity the matrix rho(Gamma) is precisely the Hamiltonian operator (suitably normalized) of a non-relativistic quantum particle interacting with the quantum gravitational field, if we restrict elementary area and volume eigenvalues to a fixed value. This operator provides a spectral characterization of the physical geometry, and can be interpreted as a state describing the spectral information about the geometry available when geometry is measured by its physical interaction with matter. It is then tempting to interpret its BGS entropy S(Gamma) as a genuine physical entropy: we discuss the appeal and the difficulties of this interpretation.

description: This study investigates the effects of digital finance technology, i.e., mobile phones and internet usage on financial stability of the banking sector in developing market economies. We used data from 2000 to 2020 from 55 selected developing economies to examine the link between digital finance technology and financial stability. According to the empirical results from the quantile regression, mobile phone subscriptions as a proxy for digital finance technology has a negative impact on the financial stability of the chosen emerging economies. In contrast, the findings indicate that internet usage as a proxy for digital finance technology has a favorable impact on the financial stability (FS) of developing economies. Given that digital finance technology has a variety of implications on the financial stability of emerging countries, the study advises policymakers to assess current digital finance technology (internet usage and mobile phone subscription) and banking-related regulations and align them with various aspects of financial stability.
title: Comparison of Protein, Forage, and Root Yield Data of Five Pasture Mixtures as Influenced by Clipping, Irrigation, and Nitrogen Fertilization
Creators: name: Blaser, Clair E.
Publisher: name: Utah State University
Year: 1974

description: A study was made to compare the protein and forage yield and root dry weight data of five pasture mixtures as influenced by two clipping frequencies (28 and 35 day clipping intervals), three irrigation intervals (1 inch every 5 days, 2 inches every 10 days and 4 inches every 20 days) and four levels of nitrogen fertilization (0, 50, 100, and 200 pounds per acre). The study was conducted at the Greenville Farm, Logan, Utah. The farm has about 1 percent surface slope and is a well-drained Millville silt loam that occurs on an alluvial fan. It is high in potash and phosphorous and is alkaline, having a pH of 7.9 to 8.2.
Only mixtures gave significant percent forage protein results . Clipping, irrigation and fertilization treatments did not significantly affect the percent of forage protein but did affect the forage yield and thus the total protein production per acre. The total forage protein yield increases were n early lineal with the nitrogen treatment increases.
The yield of forage from the 35 day clipping frequency was greater than from the 28 day clipping frequency for all five mixtures. The mixtures containing alfalfa showed greater response to the harvest frequency in increased forage yield than the other mixtures.
All nitrogen applications gave forage yield increases. The first 50 pound increment gave the greatest and the second 50 pound increment gave the l east forage yield response.
The different irrigation intervals, with the same total seasonal water applied, resulted in no significant forage yield differences.
Ladino clover had the greatest root dry weight per acre with the 28 day harvests and 50 pounds of nitrogen. The alfalfa and grass root dry weights per acre were largest with the 35 day harvests, the first 50 pound increment of nitrogen application and the longest irrigation lnterval. A mixture of alfalfa and intermediate wheatgrass had the high alfalfa root dry weight and the low grass root dry weight yield per acre.
Ladino clover roots were high in both the percent and pounds of total available carbohydrates (TAG) per acre with the 20 day irrigation interval and with five harvests. Grass roots percent and total pounds of TAG per acre were high with five harvests. Alfalfa root TAG per acre was nearly double with four harvests over five harvests and showed the greatest response to the first 50 pounds of nitrogen and the 20 day irrigation interval.
Five harvests gave higher root to forage (R/F) ratios for all mixtures except the ladino clover-grass mixture.
Zero pounds of nitrogen gave the highest R/F ratio for the grass-only mixture. Fifty pounds of nitrogen gave the highest R/F ratios for the other four mixtures.

description: The purpose of this paper is to determine the economic feasibility of the Akkar Plain Agricultural Development Project. Data were collected at representative villages throughout the Akkar Plain in Syria. The data were used to establish the economic setting at the present time on the Akkar Plain and to establish a basis for determining the economic justification for the future planned developments. Methodology used was a farm budget analysis of a before development and after development situation. Internal rate of return and benefit/cost ratio were the measures used to determine economic feasibility. The paper discusses previous work completed, the development plan, methodology used, and analysis of results in that order.
A study of certain types of surface waveguides
Creators: name: Lewis, John Eugene
Publisher: name: University of British Columbia
Year: 2011

description: This work consists of two parts. The first part is a comprehensive study of surface-wave propagation along dielectric tube waveguides. It includes the derivation of the characteristic equations and expressions for group velocity and attenuation coefficient, the latter by a perturbation method. Mode designations are justified and the physical distinction between the HE₁₁ and EH₁₁ modes is further illustrated by showing three-dimensional plots of the field configurations. Computed characteristics are given for a wide range of parameters, and are compared with those of standard rectangular waveguides. Finally, a method of shielding the tube from weather conditions is proposed and the resulting changes in characteristics are noted. The second part of this work is essentially a unified analysis of all slow-wave modes in eight cylindrical waveguides. Characteristic equations are derived and expressions are obtained for the group velocity and the attenuation coefficients by a perturbation method. Accurate propagation characteristics for the dominant TM₀₁ mode are computed for four waveguides with no restrictions on their radial dimensions. These guides are the Goubau line and a coaxial cable with dielectric linings on the inner, outer, or both conductors.

description: Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures. It can provide long-term confidentiality for encrypted information without reliance on computational assumptions. Although QKD still requires authentication to prevent man-in-the-middle attacks, it can make use of either information-theoretically secure symmetric key authentication or computationally secure public key authentication: even when using public key authentication, we argue that QKD still offers stronger security than classical key agreement.

description: Eating disorders are complex heritable conditions influenced by both genetic and environmental factors. Given the progress of genomic discovery in anorexia nervosa, with the identification of the first genome-wide significant locus, as well as animated discussion of epigenetic mechanisms in linking environmental factors with disease onset, our goal was to conduct a systematic review of the current body of evidence on epigenetic factors in eating disorders to inform future directions in this area. Following PRISMA guidelines, two independent authors conducted a search within PubMed and Web of Science and identified 18 journal articles and conference abstracts addressing anorexia nervosa (n = 13), bulimia nervosa (n = 6), and binge-eating disorder (n = 1), published between January 2003 and October 2017. We reviewed all articles and included a critical discussion of field-specific methodological considerations. The majority of epigenetic analyses of eating disorders investigated methylation at candidate genes (n = 13), focusing on anorexia and bulimia nervosa in very small samples with considerable sample overlap across published studies. Three studies used microarray-based technologies to examine DNA methylation across the genome of anorexia nervosa and binge-eating disorder patients. Overall, results were inconclusive and were primarily exploratory in nature. The field of epigenetics in eating disorders remains in its infancy. We encourage the scientific community to apply methodologically sound approaches using genome-wide designs including epigenome-wide association studies (EWAS), to increase sample sizes, and to broaden the focus to include all eating disorder types.
title: A Study Concerning Sources of Information and Knowledge About Fluoride in Logan, Milford, and Helper, Utah
Creators: name: Geddes, Marilyn Lorraine
Publisher: name: Utah State University
Year: 1974

description: A considerable amount of research has been conducted concerning the characteristics of people who are in favor of fluoridation . However, there is little information available as to what the electorate really knows about fluoride when they are forced to vote on this scientific issue.
Thus, the objectives of this study were to determine the general public's level of knowledge about fluoride, to discover what sources of information have been the greatest influence on their opinion and knowledge about fluoride, and to estimate the level of participation of dentists, general practitioners, pediatricians, and gynecologists in the education of Utahns about the use of fluoride as related to human health.
The results of this investigation revealed that the general public greatly lacks the necessary information about fluoride to vote intelligently upon the issue of fluoridation. Television, dentists, magazines, and newspapers respectively were found to have the greatest influence on the public's opinion and knowledge about fluoride. It was also determined that 68 percent of the dentists practicing in Utah provide dental health education for their patients, but that their programs are not as effective as they could be. In addition, even though 80 percent of the pediatricians, general practitioners, and gynecologists practicing in Utah are involved in educating their patients about fluoride, the general public does not consider the physician as a major source of information about fluoride.
A statistical analysis of the data from the knowledge questionnaire revealed a significant relationship between education, age, sources of information and level of knowledge about fluoride.

description: Compulsive buying is a relatively modern stereotypical disorder that interferes with our daily lives and causes serious mental and financial problems. Most studies provided information on an impulsive characteristic that causes compulsive buying and addiction, whereas a lack of studies was found on the controlling aspect of compulsive buying behavior. Using negative emotion can be the first approach for examining the relationship between self-control and propensity for compulsive purchases. The current study examined the direct influence of self-control on compulsive buying behavior (CBB) as well as the role of ill-being perception as a mediator in the relationship between self-control and CBB. An online survey was conducted to collect relevant data. A total of 639 buyers, both males and females of various ages, completed questionnaires. Correlation and mediation analysis revealed that self-control positively affected compulsive buying whereas ill-being perception negatively influences the CBB. Further, Ill-being perception had a mediating effect on self-control and CBB. The results further showed that to avoid the negative effects of compulsive buying behavior, buyers should be trained to improve self-control by inducing negative emotions related to CBB.
title: Measuring Natural Resource Scarcity Under Common Property Environment and Uncertainty: An Interpretive Analysis
Creators: name: Ghosh, Soumendra N.
Publisher: name: Utah State University
Year: 1987

description: The issue of natural resource scarcity has so far been addressed in the literature on the basis of various measures such as the unit cost of production, the relative market price, and the shadow price of a resource. Although it has been recognized that there exists some kind of jointness (sometimes inseparable) between an extractible resource and its surrounding environment, none of the measures, either theoretically or empirically, have included this concern.
In order to extract and use a natural resource (e.g., coal) the environment (air, water, etc.) must also be used as a repository of the discharged wastes (e.g., sulphur oxides, nitrous oxides, particulates, etc.) . Moreover, if there is a mandated level of the environmental resource (e. g., clean air) that has to be maintained, then certain additional costs must be borne by society (firms utilizing the resource). Thus, in evaluating the scarcity of an extractible resource, the relative position of the environmental resource also must be evaluated. The present study has incorporated such jointness in the evaluation of the measure of resource scarcity.
The theoretical model has been developed in an optimal control framework. It has been analytically shown that this new measure of resource scarcity would indicate a different trend compared to earlier ones. The measure of resource scarcity developed in this study captures previous measures as special cases. In an uncertain world, when the impacts of use of an extractible resource on the environment is not known the stock size of the environmental resource becomes uncertain. It has been analytically shown that in a situation of uncertain environmental stock the scarcity indicator would indicate a relatively slower extraction compared to that of a deterministic world.
Empirical investigations in this study suggest that coal in use might be becoming relatively scarce if one considers the use of it in the electricity industry as the major use, compared to a situation where no environmental concerns are in effect.

description: The Covid −19 pandemic has caused businesses to experience a sharp revenue decline due to lockdown policies. It takes resilience and effective leadership to steer businesses through this period of uncertainties. This paper examines how servant leadership (SL) moderates the relationship between grit facets (comprising of the perseverance of effort (PE) and the consistency of interest (CI) among Small and Medium Enterprises (SMEs) business survival (BS) during the COVID-19 pandemic. This study employed a cross-sectional survey method with a purposive sampling method toward employees from 425 SMEs located in West Java, the province hosting Indonesia’s highest number of SMEs. The questionnaire items were adapted from previous studies to encompass the variables in question effectively. The partial least square was employed in data analysis, revealing that PE positively affects BS (p = 0.012). The SL approach also strengthens the positive influence of PE on SME BS (p = 0.018). Theoretically, this study contributes to filling the gaps in the entrepreneurship literature involving grit and leadership types (in this context, servant leadership). Specifically, the results demonstrate how SL strengthens the grit characteristics in fostering SMEs” resilience during crises. On the practical front, the findings provide insights for entrepreneurs to utilize the SL approach to enhance the SMEs” resilience during the crisis. Additionally, the results offer policy recommendations to the Government to foster the development of SL and grit character among SMEs. This approach produces longer-lasting impacts and decreases reliance on governmental aid.

description: Anorexia nervosa (AN) is a severe psychiatric disorder with high mortality and, to a large extent, unknown pathophysiology. Structural brain differences, such as global or focal reductions in grey or white matter volumes, as well as enlargement of the sulci and the ventricles, have repeatedly been observed in individuals with AN. However, many of the documented aberrances normalize with weight recovery, even though some studies show enduring changes. To further explore whether AN is associated with neuronal damage, we analysed the levels of neurofilament light chain (NfL), a marker reflecting ongoing neuronal injury, in plasma samples from females with AN, females recovered from AN (AN-REC) and normal-weight age-matched female controls (CTRLS). We detected significantly increased plasma levels of NfL in AN vs CTRLS (medianAN = 15.6 pg/ml, IQRAN = 12.1–21.3, medianCTRL = 9.3 pg/ml, IQRCTRL = 6.4–12.9, and p < 0.0001), AN vs AN-REC (medianAN-REC = 11.1 pg/ml, IQRAN-REC = 8.6–15.5, and p < 0.0001), and AN-REC vs CTRLS (p = 0.004). The plasma levels of NfL are negatively associated with BMI overall samples (β (±se) = −0.62 ± 0.087 and p = 6.9‧10−12). This indicates that AN is associated with neuronal damage that partially normalizes with weight recovery. Further studies are needed to determine which brain areas are affected, and potential long-term sequelae.

description: In this short note we discuss discrete torsion in orientifolds. In particular, we apply the physical understanding of discrete torsion worked out several years ago, as group actions on B fields, to the case of orientifolds, and recover some old results of Braun and Stefanski concerning group cohomology and twisted equivariant K theory. We also derive new results including phase factors for nonorientable worldsheets and analogues for C fields.

title: The Cost of a Home Economics Food Program in the State of Utah
Creators: name: Winterton, Joyce Leavitt
Publisher: name: Utah State University
Year: 1974

description: The purposes of this paper are to provide a guid.e line for determining the budget for a Consumer and Homemaking foods program in the secondary schools of Utah, and to suggest some food buying procedures. In order to achieve these purposes, questionnaires were sent to the 167 ,junior and senior high schools in the state. Of the questionnaires returned, 99 were complete enough to be utilized for the study; 48 were from junior high schools and 51 from senior high schools. For analysis the schools were grouped according to whether they were a junior or senior high school and then into large, medium or small schools based on the total number of students in each school.
From the information on the completed questionnaires, cost for one 36-weeks course in a foods program and the cost per student per hour for each school was determined. The averages were then found for each category. It was determined that except for the small junior high schools the cost per 36-weeks course appears to increase with a decrease in the size of the school. The figures indicate that there is an inverse relationship between the cost per student per hour and the population of the schools. Even though the larger schools have a greater total budget than the smaller schools, they offer more courses and serve more students which results in a lower cost per student per hour and fewer dollars involved in each 36-weeks course.
It was also determined that the schools which purchased staple food supplies through the school district appeared to have lower costs per student per hour. The results indicated that it was not necessarily cheaper to purchase food at a large chain store as compared to a small local store. Allocating a budget on a total year basis seems to result in a lower total budget per year. The schools which operated on more money per student hour indicated a difference in their purchasing of food which included the higher priced meats and preparing more complete meals.
It is suggested that teachers and administrators be aware of the quality of a foods program in relation to the costs of the program, and the budget allowed for the outcomes desired.
title: Economic Simulation of Selected Management Strategies for a Typical Dairy Farm Faced with Declining Milk Prices
Creators: name: Balls, M. Reed
Publisher: name: Utah State University

description: The purpose of this thesis is to study the effect of lower milk support prices trigger ed by chronic surplus production problems and to offer alter native management strategies for dairymen caught in the cash flow squeeze precipitated by resulting cuts in the producer price of milk. Historical dairy policy is reviewed and recommendations are offered for consideration in developing dairy policy over the next decade.
FLIPSIM V, a powerful, firm-level computerized simulation model is employed to predict the probable outcome of employing alternative management strategies designed to improve profitability for individual dairymen. The study focuses on a typical farm devised from survey data to be representative of Utah's dairy industry. A five-year planning horizon is simulated.

description: Eating disorders are severe illnesses characterized by both psychiatric and metabolic factors. We explored the prospective role of metabolic risk in eating disorders in a UK cohort (n = 2929 participants), measuring 158 metabolic traits in non-fasting EDTA-plasma by nuclear magnetic resonance. We associated metabolic markers at 7 years (exposure) with risk for anorexia nervosa and binge-eating disorder (outcomes) at 14, 16, and 18 years using logistic regression adjusted for maternal education, child's sex, age, body mass index, and calorie intake at 7 years. Elevated very low-density lipoproteins, triglycerides, apolipoprotein-B/A, and monounsaturated fatty acids ratio were associated with lower odds of anorexia nervosa at age 18, while elevated high-density lipoproteins, docosahexaenoic acid and polyunsaturated fatty acids ratio, and fatty acid unsaturation were associated with higher risk for anorexia nervosa at 18 years. Elevated linoleic acid and n-6 fatty acid ratios were associated with lower odds of binge-eating disorder at 16 years, while elevated saturated fatty acid ratio was associated with higher odds of binge-eating disorder. Most associations had large confidence intervals and showed, for anorexia nervosa, different directions across time points. Overall, our results show some evidence for a role of metabolic factors in eating disorders development in adolescence.

description: Anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) are heritable conditions that are influenced by both genetic and environmental factors. Recent genome-wide association studies (GWAS) of AN have identified specific genetic loci implicated in AN, and genetic correlations have implicated both psychiatric and metabolic factors in its origin. No GWAS have been performed for BN or BED. Genetic counseling is an important tool and can aid families and patients in understanding risk for these illnesses.
title: Characteristics and Genesis of the Parleys and Mendon Soils Series in Northern Utah
Creators: name: Al-Amin, Khalid I.
Publisher: name: Utah State University
Year: 1974

description: The study was designed to test the genetic theory of soil development of two soils derived from different geological material , but developed under conditions of similar climate, topography, biological activity, and age. An attempt was made to relate the soils characteristics to their present classification. Parleys and Mendon series which developed from Bonneville and Salt Lake Formation, respectively, were selected for that purpose. Along the east side of Cache valley , two pedons representing each of the studied series were selected to have similar soil formers except for their parent material.
Evidently , these studied soils have been developed (rom different heterogenous sediments. Mendon soils have been developed from Salt Lake Formation to at least 51 cm depth, whereas, the solum horizons are attributed to the Bonneville Formation. The Parleys soil seems to be mainly developed from Bonneville formation. But the upper solum horizons are probably interlayered with fine deposits of Holocene age. Those soils which derived from different geological deposits show a high degree of similarity between them. Heterogeneity and the nature of the soil parent material, and similarity of their climatic and developmental conditions are believed to be the major causes to inhibit many genetic variables between them.
In northern Utah, the Hendon soils are classified as Calcic Pachic Argixerolls, at the subgroup level. This study has shown that most of the Mendon pedons do not have a Pachic epipedon. Therefore, these studied soils could be grouped together in one subgroup. The result is Calcic Argixerolls in ftne-silty, mixed, mesic family. Re-examining Mendon series in Cache valley and reclassifying them on the basis of Pachic epipedon would be an interesting subject for further study.

description: We present the first case of strong gravitational lensing by a QSO : SDSS J0013+1523, at z = 0.120. The discovery is the result of a systematic search for emission lines redshifted behind QSOs, among 22298 spectra of the SDSS data release 7. Apart from the z = 0.120 spectral features of the foreground QSO, the spectrum of SDSS J0013+1523 also displays the OII and Hbeta emission lines and the OIII doublet, all at the same redshift, z = 0.640. Using sharp Keck adaptive optics K-band images obtained using laser guide stars, we unveil two objects within a radius of 2 arcsec from the QSO. Deep Keck optical spectroscopy clearly confirms one of these objects at z = 0.640 and shows traces of the OIII, emission line of the second object, also at z = 0.640. Lens modeling suggests that they represent two images of the same z = 0.640 emission-line galaxy. Our Keck spectra also allow us to measure the redshift of an intervening galaxy at z = 0.394, located 3.2 arcsec away from the line of sight to the QSO. If the z = 0.120 QSO host galaxy is modeled as a singular isothermal sphere, its mass within the Einstein radius is M_E(r < 1 kpc) = 2.16e10 M_Sun and its velocity dispersion is sigma_SIS = 169 km/s. This is about 1 sigma away from the velocity dispersion estimated from the width of the QSO Hbeta emission line, sigma_*(M_BH) = 124 +/- 47 km/s. Deep optical HST imaging will be necessary to constrain the total radial mass profile of the QSO host galaxy using the detailed shape of the lensed source. This first case of a QSO acting as a strong lens on a more distant object opens new directions in the study of QSO host galaxies.
