description: The purpose of this study was to examine the effects of message framing strategies and approach avoidance trait moderators on health communication intervention messages aimed at encouraging adaptive coping among parents of those children with eating disorders (PCEDs). Parents of children with eating disorders (N = 108) were randomly assigned in a three-condition (gain frame, loss frame, and control) online message pretesting experiment. Outcome measures included decisional balance (Transtheoretical Model) and behavioral intentions. Gain frames were more beneficial in promoting adaptive behaviors among PCEDs, as loss frames were often harmful. Findings are qualified by approach/avoidance moderator interactions. Formative research benefits from incorporating experimental pretesting methods. Interventions using framed messages should consider relevant personality traits that serve as moderators to behavior adoption.

description: Ο θεσμός της αξιολόγησης του εκπαιδευτικού αποτελεί ένα ζήτημα, το οποίο βρίσκεται στο επίκεντρο έντονων συζητήσεων και αντιδράσεων εντός της εκπαιδευτικής κοινότητας, λόγω της κοινωνικής και δη της ιδεολογικής διάστασης που προσλαμβάνει. Το ζήτημα αυτό επανήλθε με έντονο τρόπο στο προσκήνιο με την ψήφιση και εισαγωγή του νέου νόμου 4823/2021, σε συνδυασμό και με το νέο «σώμα» νεοδιόριστων εκπαιδευτικών, οι οποίοι μονιμοποιήθηκαν κατά το ίδιο έτος. Σκοπός της παρούσας εργασίας είναι η διερεύνηση των αντιλήψεων και των στάσεων των νεοδιόριστων εκπαιδευτικών και των εκπαιδευτικών με πολυετή εκπαιδευτική προϋπηρεσία της Πρωτοβάθμιας Εκπαίδευσης για τον θεσμό της αξιολόγησής τους, όπως προωθείται από την κρατική εξουσία, προκειμένου να εντοπισθούν τυχόν κοινά σημεία ή διαφοροποιήσεις των απόψεων των δύο κατηγοριών εκπαιδευτικών, δεδομένων των διαφορετικών εμπειριών και των βιωμάτων που καθεμία από αυτές κατέχει. Αξίζει να σημειωθεί ότι μέχρι σήμερα δεν έχουν ερευνηθεί οι απόψεις και η στάση των νεοδιόριστων εκπαιδευτικών σχετικά με το ζήτημα της αξιολόγησής τους. Δείγμα της παρούσας έρευνας αποτέλεσαν δεκατέσσερις (14) εκπαιδευτικοί, επτά εκ των οποίων με πολυετή εκπαιδευτική προϋπηρεσία και επτά νεοδιόριστοι, οι οποίοι, μέσω της ερευνητικής τεχνικής των ημιδομημένων συνεντεύξεων, κλήθηκαν να αποτυπώσουν τις απόψεις τους σχετικά με το θεσμό της αξιολόγησης. Οι απόψεις τους διαφοροποιούνται ανάμεσα στις δύο κατηγορίες, ωστόσο συμφωνούν στο ότι ο θεσμός της αξιολόγησης δεν πρέπει να έχει ελεγκτικό χαρακτήρα, αλλά αντίθετα να εγγυάται την ανατροφοδοτική και βελτιωτική του διάσταση.

description: We study the partition function for the three-colour model with domain wall boundary conditions. We express it in terms of certain special polynomials, which can be constructed recursively. Our method generalizes Kuperberg's proof of the alternating sign matrix theorem, replacing the six-vertex model used by Kuperberg with the eight-vertex-solid-on-solid model. As applications, we obtain some combinatorial results on three-colourings. We also conjecture an explicit formula for the free energy of the model.

description: The normal-state charge transport is studied systematically in high-quality single crystals of BaFe$_2$(As$_{1-x}$P$_x$)$_2$ ($0 \leq x \leq 0.71$). By substituting isovalent P for As, the spin-density-wave (SDW) state is suppressed and the dome-shaped superconducting phase ($T_c \lesssim 31$ K) appears. Near the SDW end point ($x\approx0.3$), we observe striking linear temperature ($T$) dependence of resistivity in a wide $T$-range, and remarkable low-$T$ enhancement of Hall coefficient magnitude from the carrier number estimates. We also find that the magnetoresistance apparently violates the Kohler's rule and is well scaled by the Hall angle $Θ_H$ as $Δρ_{xx}/ρ_{xx} \propto \tan^2Θ_H$. These non-Fermi liquid transport anomalies cannot be attributed to the simple multiband effects. These results capture universal features of correlated electron systems in the presence of strong antiferromagnetic fluctuations.

Year: 1971

description: The definition of aide for this study was a non-certified person in the classroom who aids and assists the professional with non-related tasks.
The present role of the teacher aide in Home Economics was described and suggested guidelines for future aide utilization were proposed.
The study was conducted in three phases : 1) Personal Interviews were conducted of three teacher aides and two teachers presently employed in Utah. 2) Correspondence with fifty program directors or teachers using aides in other states. 3) Time-Activity analysis of 12 junior and senior high Home Economics teachers.
Instruments used were: 1) A twelve item interview for teacher aides, and 2) A twenty-two item interview for teacher aides, 3) A fifty-two item questionnaire form was formulated by the writer.
The findings of the thesis are: 1) It was found that teacher aides were not used extensively in Home Economics classes in Utah or throughout the United States. 2) No provision is made for educational training or a career ladder. 3) There is no role definition for the aide in the present program. 4) The aide program has received positive acceptance by the teachers, professional staff and students involved in the program. 5) Careful selection, open communication and role definition were suggested as determinents of successful programs.

description: Besides the well-known effect of autocorrelations in time series of Monte Carlo simulation data resulting from the underlying Markov process, using the same data pool for computing various estimates entails additional cross correlations. This effect, if not properly taken into account, leads to systematically wrong error estimates for combined quantities. Using a straightforward recipe of data analysis employing the jackknife or similar resampling techniques, such problems can be avoided. In addition, a covariance analysis allows for the formulation of optimal estimators with often significantly reduced variance as compared to more conventional averages.

description: Purpose A subgroup of individuals with anorexia nervosa (AN) displays social difficulties; however, it is not clear if individuals with comorbid autism spectrum disorders account for these difficulties. Methods We compared social function using the Autism Diagnostic Observation Schedule in 43 young females with first-episode AN who did not have comorbid autism spectrum disorder, 28 individuals recovered from adolescent-onset AN, and 41 healthy comparison individuals (age range 14–22 years). We measured adaptive behavior with the Vineland-II parent questionnaire, and aspects of social cognition with psychological tests, such as the Reading-the-Mind-in-the-Eyes test, Profile of Nonverbal Sensitivity short version, The Awareness of Social Inference Test, Animated Triangles, and the CANTAB Affective Go/No-go task. Results Participants with first-episode AN and those recovered from AN displayed difficulties in social function, which were not associated with body mass index or other state factors of the disorder in those with first-episode AN. Mood problems and anxiety were not associated with these difficulties. Parents rated participants with first-episode AN lower than recovered and control participants on the Socialization Domain of Vineland-II. Finally, only participants recovered from AN demonstrated deficits in specific domains of social cognition: perceiving nonverbal bodily gesture and vocal prosody. Conclusions Young females with first-episode AN and those recovered from AN displayed impairments in social function, which may represent more stable traits of the disorder. Only participants recovered from AN demonstrated deficits in social cognition.

Livestock--Mortality
Livestock--Climatic factors

description: Recent incidences of mass livestock mortality, known as dzud, have called into question the sustainability of pastoral nomadic herding, the cornerstone of Mongolian culture. A total of 20 million head of livestock perished in the mortality events of 2000–2002, and 2009–2010. To mitigate the effects of such events on the lives of herders, international agencies such as the World Bank are taking increasing interest in developing tailored market-based solutions like index-insurance. Their ultimate success depends on understanding the historical context and underlying causes of mortality. In this paper we examine mortality in 21 Mongolian aimags (provinces) between 1955 and 2013 in order to explain its density independent cause(s) related to climate variability. We show that livestock mortality is most strongly linked to winter (November–February) temperatures, with incidences of mass mortality being most likely to occur because of an anomalously cold winter. Additionally, we find prior summer (July–September) drought and precipitation deficit to be important triggers for mortality that intensifies the effect of upcoming winter temperatures on livestock. Our density independent mortality model based on winter temperature, summer drought, summer precipitation, and summer potential evaporanspiration explains 48.4% of the total variability in the mortality dataset. The Mongolian index based livestock insurance program uses a threshold of 6% mortality to trigger payouts. We find that on average for Mongolia, the probability of exceedance of 6% mortality in any given year is 26% over the 59 year period between 1955 and 2013.
title: A Study of the Effects of Water Institutions on Planning and Management of Water Resources in Utah
Creators: name: McLean, Donald H.
Publisher: name: Utah State University
Year: 1972

description: One area of research that has been somewhat neglected in water planning programs and water development is that pertaining to water law and water institutions. Over the years each state has developed a complex system of water law and organizations for the allocation and distribution of water. The usual role of these institutions is one of orderly development and the efficient use of the water resource. However, in many cases water law and institutions have imposed serious constraints upon the planning and the most efficient use of a valuable resource.
This study, through historic research, has attempted to define these water institutions in the state of Utah. In order to fully identify these agencies an in-depth study was made of the active water institutions in Weber County. This was accomplished through personal interviews, review of articles of incorporation, court records, annual reports and similar documents.
The study has revealed that all of these institutions as established by legislation have the opportunity to overlap in areas of jurisdiction, sources of water and potential customers. This possibility of overlapping or duplication of services exists but may not necessarily be practiced.
The most serious legislative omission is the lack of vertical coordination between the state and local agencies and horizontal cooperation among institutions operating in the same area. This lack of coordination and cooperation has precluded the most efficient use and development of the water resources of the state.

description: The anomaly in the low energy distribution of quasi-elastic neutrino events reported by the MiniBooNE collaboration is discussed. We show that the observed excess of electron-like events could originate from the production and decay of a heavy neutrino ($ν_h$) in the MiniBooNE detector. The $ν_h$ is created by mixing in $ν_μ$ neutral-current interactions and decays radiatively into $ νγ$ due to a transition magnetic moment between the $ν_h$ and a light neutrino $ν$. The energy measured in the detector arises from the subsequent conversion of the decay photon into a $\pair$ pair within the detector volume. The analysis of the energy and angular distributions of the excess events suggests that the $ν_h$ has a mass around 500 MeV and the lifetime $τ_{ν_h} \lesssim 10^{-9}$ s. Existing experimental data are found to be consistent with a mixing strength between the $ν_h$ and the $ν_μ$ of $|U_{μh}|^2 \simeq (1-4)\times 10^{-3}$ and a $ν_h$ transition magnetic moment of $ μ_{tr} \simeq (1- 6)\times 10^{-9} μ_B$. Finally, we discuss the reason why no significant excess of low energy events has been observed in the recent antineutrino data.

description: A planned array of 200,000 antennas covering an area of 200,000 km$^{2}$ the GRAND project is proposed to detect cosmic-ray, gamma-ray, and neutrino primaries in the energy range beyond 10$^{17}$eV. The GRAND array will be able to detect upward-going air showers initiated by neutrino interactions in the rocks on its mountainous site, furthermore, it may also detect very inclined and atmosphere-skimming air showers initiated by cosmic rays. So the corresponding shower geometry differs from the other experiments and asks for a detailed investigation. To meet the requirements of GRAND, we develop an update of CORSIKA7 for the simulation of upward-going air showers. Furthermore, we apply today’s best knowledge of parameters of the GRAND project, in particular realistic on-site atmospheres, in an extensive library of inclined air showers. Finally, we evaluate expected signal-to-noise ratios and detection thresholds for the GrandProto300 (GP300) phase of GRAND.

Ωστόσο, στις διάφορες εκθέσεις αξιολόγησης της ψηφιακής της ετοιμότητας, η Ελλάδα έχει λάβει αντικρουόμενα αποτελέσματα. Η παρούσα μελέτη στοχεύει να εξετάσει τον τρόπο με τον οποίο εφαρμόστηκαν στην Ελλάδα οι στρατηγικές και οι στόχοι της ηλεκτρονικής διακυβέρνησης που προτάθηκαν από την Ευρωπαϊκή Επιτροπή από το 2006 έως το 2020. Τα ευρήματα δείχνουν ότι η Ελλάδα διαφοροποιήθηκε από την προτεινόμενη στρατηγική και ακολούθησε ένα διαφορετικό πλαίσιο ψηφιακού μετασχηματισμού.

Τα αποτελέσματα δείχνουν ότι οι μεθοδολογίες από την πλευρά της ζήτησης παρέχουν μια πιο ολοκληρωμένη αξιολόγηση της ποιότητας της πύλης ηλεκτρονικής διακυβέρνησης, ενώ οι αντικειμενικές μέθοδοι που χρησιμοποιούν αυτοματοποιημένα εργαλεία απαιτούν περαιτέρω ανάπτυξη. Η ανάλυση καταλήγει στο συμπέρασμα ότι οι δήμοι αποδίδουν σε μεσαίο επίπεδο όσον αφορά την ποιότητα της Ηλεκτρονικής Διακυβέρνησης σε όλες τις μεθόδους, με κύριο θέμα την έλλειψη χρησιμότητας. Λαμβάνοντας υπόψη την συγκεκριμένη έλλειψη, χρησιμοποιήθηκε η προσέγγιση πληθοπορισμού (crowdsourcing) για να συλλεχθούν οι απόψεις των πολιτών αναφορικά με τις υπηρεσίες που επιθυμούν να παρέχονται μέσω των πυλών ηλεκτρονικής διακυβέρνησης. Η μελέτη καταλήγει σε μια νέα τυπολογία σχετικά με τον τρόπο με τον οποίο πρέπει να αναπτυχθούν οι πύλες ηλεκτρονικής διακυβέρνησης προκειμένου να θεωρηθούν χρήσιμες.

description: Background: For too long we have been "stuck" in old perspectives that have hampered the advance of knowledge. In part, this is related to the challenges that people have in unlearning misinformation. Aim: To address the need for an upgrade in the eating disorders field. Method: To assist with replacing outdated and inaccurate ideas with new data, this lecture reviewed novel approaches to eating disorders that engage scientists and clinicians from diverse fields to approach questions about aetiology and treatment of eating disorders through new lenses. This forward-looking lecture outlined critical questions that need to be addressed to move the field forward and strategies for engaging scientists from different fields. Results: Leading-edge findings on genetics, intestinal microbiota, and neuroscience are reviewed. Conclusions: This review encourages the integration of new evidence-based knowledge to form the backbone of our understanding of and approach to eating disorders.

description: Massive stars end their life in an explosion event with kinetic energies of the order 1 Bethe. Immediately after the explosion has been launched, a region of low density and high entropy forms behind the ejecta which is continuously subject to neutrino heating. The neutrinos emitted from the remnant at the center, the protoneutron star (PNS), heat the material above the PNS surface. This heat is partly converted into kinetic energy and the material accelerates to an outflow that is known as the neutrino driven wind. For the first time, we simulate the collapse, bounce, explosion and the neutrino driven wind phases consistently over more than 20 seconds. Our numerical model is based on spherically symmetric general relativistic radiation hydrodynamics using spectral three flavor Boltzmann neutrino transport. In simulations where no explosions are obtained naturally, we model neutrino driven explosions for low and intermediate mass Fe-core progenitor stars by enhancing the charged current reaction rates. In the case of a special progenitor star, the O-Ne-Mg-core, the explosion in spherical symmetry was obtained without enhanced opacities. The post explosion evolution is in qualitative agreement with static steady-state and parametrized dynamic models of the neutrino driven wind. On the other hand, we find generally smaller neutrino luminosities and mean neutrino energies as well as a different evolutionary behavior of the neutrino luminosities and mean neutrino energies. The neutrino driven wind is proton-rich for more than 10 seconds and the contraction of the PNS differs from the assumptions made for the conditions at the inner boundary in previous neutrino driven wind studies. Despite the moderately large entropies per baryon of about 100 and the fast expansion timescale, the conditions found in our model are unlikely to favor...

description: Charged excitations in the fractional quantum Hall effect are known to carry fractional charges, as theoretically predicted and experimentally verified. Here we report on the dependence of the tunneling quasiparticle charge, as determined via highly sensitive shot noise measurements, on the measurement conditions, in the odd denominators states v=1/3 and v=7/3 and in the even denominator state v=5/2. In particular, for very weak backscattering probability and sufficiently small excitation energies (temperature and applied voltage), tunneling charges across a constriction were found to be significantly higher than the theoretically predicted fundamental quasiparticle charges.
Cosmic evolution of submillimeter galaxies and their contribution to stellar mass assembly

description: The nature of galaxies selected at submillimeter wavelengths (SMGs, S_850 > 3 mJy), some of the bolometrically most luminous objects at high redshifts, is still elusive. In particular their star formation histories and source of emission are not accurately constrained. In this paper we introduce a new approach to analyse the SMG data. Namely, we present the first self-consistent UV-to-radio spectral energy distribution fits of 76 SMGs with spectroscopic redshifts using all photometric datapoints from ultraviolet to radio simultaneously. We find that they are highly star-forming (median star formation rate 713 MSun yr^-1 for SMGs at z>0.5), moderately dust-obscured (median A_V~2 mag), hosting significant stellar populations (median stellar mass 3.7x10^11 MSun) of which only a minor part has been formed in the ongoing starburst episode. This implies that in the past, SMGs experienced either another starburst episode or merger with several galaxies. The properties of SMGs suggest that they are progenitors of present-day elliptical galaxies. We find that these bright SMGs contribute significantly to the cosmic star formation rate density (~20%) and stellar mass density (~30-50%) at redshifts 2-4. Using number counts at low fluxes we find that as much as 80% of the cosmic star formation at these redshifts took place in SMGs brighter than 0.1 mJy. We find evidence that a linear infrared-radio correlation holds for SMGs in an unchanged form up to redshift of 3.6, though its normalization is offset from the local relation by a factor of ~2.1 towards higher radio luminosities. We present a compilation of photometry data of SMGs and determinations of cosmic SFR and stellar mass densities.

description: We develop a generalization of the Black-Cox structural model of default risk. The extended model captures uncertainty related to firm's ability to avoid default even if company's liabilities momentarily exceeding its assets. Diffusion in a linear potential with the radiation boundary condition is used to mimic a company's default process. The exact solution of the corresponding Fokker-Planck equation allows for derivation of analytical expressions for the cumulative probability of default and the relevant hazard rate. Obtained closed formulas fit well the historical data on global corporate defaults and demonstrate the split behavior of credit spreads for bonds of companies in different categories of speculative-grade ratings with varying time to maturity. Introduction of the finite rate of default at the boundary improves valuation of credit risk for short time horizons, which is the key advantage of the proposed model. We also consider the influence of uncertainty in the initial distance to the default barrier on the outcome of the model and demonstrate that this additional source of incomplete information may be responsible for non-zero credit spreads for bonds with very short time to maturity.

description: Objective: Recent research has suggested a move toward a dimensional system for the classification of personality disorders (PDs). Tyrer's dimensional model using severity as a form of categorizing PDs was used to compare eating disorder outcome in women with bulimia nervosa (BN) over 3 years. Method: One hundred thirty-four women with BN were divided into 4 groups based on PD severity: no PD (n = 32), personality difficulty (n = 27), simple PD (n = 29), and complex PD (n = 46). Eating disorder symptoms and attitudes, general psychosocial functioning, and depressive symptoms were examined at pretreatment and at 1-year and 3-year follow-up (posttreatment). Results: The complex PD group had greater Axis I comorbidity and psychopathology than the remaining 3 groups at pretreatment. At 1-year and 3-year follow-up, there were no differences in eating disorder outcome, general psychosocial functioning, and depressive symptoms across the 4 groups. Conclusion: These results suggest that having an increased number of PDs comorbid with BN does not influence eating disorder outcome up to 3 years after treatment.

description: We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma-models on AdS backgrounds with Ramond-Ramond fluxes in various dimensions. We show that sigma-models based on supercosets of PSU supergroups, such as AdS_2 \times S^2 and AdS_3 \times S^3 are self-dual under fermionic T-duality, while supercosets of OSp supergroups such as non-critical AdS_2 and AdS_4 models, and the critical AdS_4 \times CP^3 background are not. We present a general algebraic argument to when a supercoset is expected to have a fermionic T-duality symmetry, and when it will fail to have one.

description: The discoveries of superconductivity in heavily boron-doped diamond (C:B) in 2004 and silicon (Si:B) in 2006 renew the interest in the superconducting state of semiconductors. Charge-carrier doping of wide-gap semiconductors leads to a metallic phase from which upon further doping superconductivity can emerge. Recently, we discovered superconductivity in a closely related system: heavily-boron doped silicon carbide (SiC:B). The sample used for that study consists of cubic and hexagonal SiC phase fractions and hence this lead to the question which of them participates in the superconductivity. Here we focus on a sample which mainly consists of hexagonal SiC without any indication for the cubic modification by means of x-ray diffraction, resistivity, and ac susceptibility.

description: We solve the recently proposed T- and Y-systems (Hirota equation) for the exact spectrum of AdS/CFT in the strong coupling scaling limit for an arbitrary quasiclassical string state. The corresponding T-functions appear to be super-characters of the SU(2,2|4) group in unitary representations with a highest weight, with the classical AdS5xS5 superstring monodromy matrix as the group element. We propose a concise first Weyl-type formula for these characters and show that they correctly reproduce the results of quasiclassical one-loop quantization in all sectors of the superstring, under some natural assumptions. We also speculate about possible relation between the T-functions and the quantum monodromy matrix.

description: We study quantum protocols among two distrustful parties. Under the sole assumption of correctness - guaranteeing that honest players obtain their correct outcomes - we show that every protocol implementing a non-trivial primitive necessarily leaks information to a dishonest player. This extends known impossibility results to all non-trivial primitives. We provide a framework for quantifying this leakage and argue that leakage is a good measure for the privacy provided to the players by a given protocol. Our framework also covers the case where the two players are helped by a trusted third party. We show that despite the help of a trusted third party, the players cannot amplify the cryptographic power of any primitive. All our results hold even against quantum honest-but-curious adversaries who honestly follow the protocol but purify their actions and apply a different measurement at the end of the protocol. As concrete examples, we establish lower bounds on the leakage of standard universal two-party primitives such as oblivious transfer.

description: We investigate the properties of the path integral over reparametrizations (= the boundary value of the Liouville field in open string theory). Discretizing the path integral, we apply the Metropolis-Hastings algorithm to numerical simulations of a proper (subordinator) stochastic process and find that typical trajectories are not Brownian but rather have discontinuities of the type of Levy's flights. We study a fractal structure of these trajectories and show that their Hausdorff dimension is zero. We confirm thereby the discretization and heuristic consideration of QCD scattering amplitudes by analytical and numerical calculations. We also perform Monte Carlo simulations of the path integral over reparametrization in the effective-string ansatz for a circular Wilson loop and discuss their subtleties associated with the discretization of Douglas' functional.

Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study is to present in a concise form information concerning the extent and quality of Slovenian translations of Pushkin's poetry and prose. The author has investigated as fully as possible the renderings of all the known Slovenian translators of Pushkin, who were active during the second half of the nineteenth century. Particular attention has been focused on the authorship of the published translations, collection of full bibliographical data and evaluation of the quality of the Slovenian renderings. A brief survey of the contents of the chapters will show broadly how the author has approached this task. Chapter I provides a short descriptive history of translation, explores in general terms the traditional and customary approach to translation and reviews the commonly accepted criteria and agreed upon principles governing translation. Furthermore, a brief comparative evaluation of existing resemblances and diversities of the Russian and Slovenian languages has been included. Chapter II provides a historical review of the Slovene-Russian cultural contacts, which date back to the sixteenth century, and then discusses the socio-cultural development of the Slovenian nation in the nineteenth century, taking especially into account the influence of the Slavophiles and Russophiles on the development of the Slovenian literature. Chapter III is devoted to the examination of the existing Slovenian renderings of Pushkin's poetry and prose; it provides short sketches of their authors, analyses the available bibliographical data, compares some of the renderings with the original texts, examines their language and attempts to assess their poetic failings or merits. Finally, added is a list of articles about Pushkin and translations which appeared in the Slovenian periodical publications.

description: Objective: The objective of the study was to assess the predictive value of personality profiles to classify individuals with bulimia nervosa (BN), pathological gambling (PG), and a nonpsychiatric comparison group while controlling for sex. Methods: The sample comprised 270 BN (241 women, 29 men), 429 PG (42 women, 387 men), and 96 comparison (nonpsychiatric) subjects (35 women, 61 men). All patients were consecutively admitted to our Psychiatry Department and were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. We administered the Temperament and Character Inventory-Revised as well as other clinical indices. Multinomial and binary logistic regression models adjusted for age and stratified by sex were used to assess the predictive value of personality in relation to group status. Results: In comparison to controls, high Novelty Seeking (P < .001) was specifically associated with a diagnosis of PG. Independently of sex, low Self-Directedness was associated with both BN (P < .001) and PG (P < .001). Some sex-specific differences were also observed; namely, women with BN and PG displayed higher Harm Avoidance and Cooperativeness than control women, whereas men with PG reported higher Reward Dependence and Persistence than control men. Conclusions: Our results suggested that, whereas there are some shared personality traits between BN and PG when compared with healthy controls, there are also some sex- and diagnostic-specific personality traits that weigh against the consideration of BN as an impulse control disorder.

description: Cognitive-behavioral therapy (CBT) is a successful treatment method for reducing symptomatology associated with bulimia nervosa (BN). Less is known regarding the impact of CBT on measures of temperament and character across treatment. We explore changes on the Temperament and Character Inventory (TCI) from pretreatment to 1-year follow-up in a sample of women with bulimia nervosa (BN). Ninety-one women who met DSM-III-R criteria for BN, completed pretreatment measures, and participated in a randomized clinical trial with a core treatment of CBT were available for follow-up at 1 year. Participants were assessed at pretreatment using the TCI as part of a larger assessment battery, and received eight sessions of CBT and eight sessions of exposure with response prevention or relaxation training. The TCI was readministered at the 1-year follow-up point. We compared TCI scores across the two administrations and explored the relation between clinical status at 1 year and TCI scores. Significant decreases in the TCI temperament scale of harm avoidance and increases in the character scale of self-directedness were observed between pretreatment and 1-year follow-up. Observed differences in these scales were independent of change in depression scores as well as other measures of therapeutic change (i.e., binge and purge frequency). We conclude that self-directedness and harm avoidance scores are positively affected by CBT. Higher scores on self-directedness not only predict treatment outcome for BN, but overall self-directedness is improved with CBT in women with BN. These results suggest that the elements of CBT affecting self-directedness may hold promise for enhancing the effectiveness of treatment for BN.
title: Economic Impact of Meeting Environmental Standards on Utah Cattle Feeders

description: This thesis is an analysis and description of pollution problems caused by large feedlots in Utah. A description of pollution caused by cattle feedlots is undertaken as part of the study.
The 26 feedlots analyzed had a capacity to/or did feed over 1,000 head. They were broken down into four groups on the basis of their pollution problems: those having no apparent pollution problem, those having minor problems, those having major problems, and those requiring relocation.
The cost impact of meeting environmental standards with regard to runoff control was found to be very slight for the cattle feeding industry as a whole - only 18 cents per head fed on the average. The feedlots with minor problems averaged costs of slightly over 2 cents per head fed. The feedlots with major problems averaged costs of almost 5 cents per head fed using the least cost method of natural evaporation ponds and mechanical disposal systems. The feedlots requiring relocation were most affected, as they averaged $1.15 per head fed loss in value of assets through relocating.
