title: Grass-Shrub Spatial Associations Over Precipitation and Grazing Gradients in the Great Basin, USA
Creators: name: Holthuijzen, Maike F.
Publisher: name: Utah State University
Year: 2015

description: Plant spatial patterns have been studied to gain insight into plant interactions such as competition and facilitation (positive plant interactions). The stress gradient hypothesis predicts that as environmental stress increases facilitation dominates, while competition dominates in less stressful conditions.
Beneficial plants (nurses) can create favorable abiotic conditions for subanopy plants. Additionally, palatable herbaceous species growing under nurse shrub canopies benefit from physical protection.
I investigated spatial associations between Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) and three native grasses (Poa secunda, Elymus elymoides, and Pseudoroegneria spicata) across a rainfall gradient in the Great Basin, USA. I also explored the effect of grazing on grass-shrub spatial associations. I hypothesized that positive shrub-grass spatial associations would become more frequent at lower rainfall levels; I further hypothesized that 1) at intermediate levels of stress, positive grass-shrub spatial associations would dominate and 2) at extreme levels of stress, positive grass-shrub spatial associations and interactions would no longer dominate. At high moisture stress, the addition of grazing stress may limit the nurse’s ability to provide to benefits to subcanopy plants.
Cover of P. secunda was greater in shrub canopy microsites than interspaces at low to moderate levels of rainfall. Cover and density of E. elymoides were greater in sagebrush canopies over most rainfall levels. Elymus elymoides and P. spicata were taller and narrower in basal width and less likely to be grazed in canopy versus interspace microsites.
I next investigated the effects of grazing intensity over a rainfall gradient and found a significant interaction of rainfall and microsite on P. secunda cover. Poa secunda formed positive interactions with A. tridentata at lower rainfall levels, regardless of grazing intensity. Its cover was significantly greater in interspaces at high rainfall compared to low rainfall sites. Elymus elymoides density was greater in canopy vs. interspace microsites, regardless of rainfall level or grazing intensity.
Plant spatial associations can indicate which nurse microsites are favorable to plant growth and may improve seeding or planting success during ecological restoration. My results suggest that exploiting sagebrush canopy microsites for restoration of native perennial grasses would improve plant establishment, growth or survival particularly in drier areas.

description: SOMMARIO I prodotti di ingegneria tissutale sono medicinali che contengono o consistono in cellule o tessuti sottoposti ad una rilevante manipolazione cos� da ottenere caratteristiche biologiche, funzioni fisiologiche e propriet� strutturali pertinenti alla finalit� di rigenerazione, riparazione o sostituzione. Nel caso di cellule e tessuti manipolati in vitro, l'obiettivo da raggiungere nel controllo dei processi di produzione e della qualit� del prodotto finale � garantire la sicurezza e l'efficacia dei prodotti da immettere nell'uso clinico. Ne consegue la necessit� di operare nel rispetto di norme proprie dei processi produttivi dei farmaci sia dal punto di vista della qualit� che della sicurezza del prodotto. Lo scopo del lavoro svolto durante il dottorato � stato lo studio e messa a punto di sistemi di produzione per la generazione di un prodotto innovativo per terapie avanzate. Si tratta di un prodotto costituito da cellule staminali mesenchimali, ottime candidate per applicazioni cliniche in medicina rigenerativa. Per la produzione di un prodotto di terapia avanzata, l?intero processo, a partire dal campione iniziale fino al prodotto finito, deve essere svolto in un?officina farmaceutica autorizzata che operi nel rispetto delle Good Manufacturing Practices (GMP). Si tratta di linee guida il cui scopo � assicurare che un farmaco sia prodotto, analizzato e rilasciato in un regime di Qualit� controllata e certificata in modo da minimizzare il pericolo che vi siano rischi non previsti per il paziente. Nella fase preliminare del processo � stata valutata la fattibilit� del metodo e sono stati definiti i protocolli da impiegare. La fase di fattibilit� ha permesso di mettere a punto la procedura di isolamento, espansione, differenziamento delle cellule staminali. E? stato possibile valutare la stabilit� genomica e le caratteristiche immunofenotipiche delle cellule a vari passaggi cellulari. Tutti i dati ottenuti durante lo studio di fattibilit� sono stati fondamentali per definire i test di controllo di qualit�, le specifiche di prodotto e i criteri di accettabilit� richiesti per la successiva convalida del processo. I risultati presentati durante lo studio di fattibilit� evidenziano come sia possibile trasferire protocolli di ricerca in processi potenzialmente applicabili in sperimentazione clinica. Alla fine del processo di convalida che prevede la produzione di tre lotti di cellule, le specifiche previste per i controlli in ingresso, durante il processo di produzione e sul prodotto finito devono risultare conformi a tutte le richieste. I passi futuri sono la validazione del processo asettico, mediante l?esecuzione di tre mediafill e la valutazione del rischio relativa alla produzione di lotti destinati alla clinica, in modo da completare la serie di studi necessari per la presentazione di una domanda di autorizzazione allo studio clinico.

Publisher: name: Utah State University
Year: 2015

description: The high-latitude electric eld fall-o region connects convection in the polar cap to the region where ring currents modify the penetration electric field equatorward of the polar cap boundary. This region is often overlooked because it falls between the limits of low latitude and high-latitude ionospheric models. However, penetrating electric fields cause large changes in ion composition; and therefore, correctly modeling the electric fields and plasma drift in this region aids in correctly specifying the ionosphere. Many ionospheric models use the Kp index as a physical driver, and so the latitude dependence of the plasma drift in the fall-o region was investigated as a function of Kp using Defense Meteorological Satellite Program ion drift data from the 2007{2010 solar minimum. Both the dusk and dawn sectors were analyzed and t to analytical functions describing the fall-o with decreasing latitude. The latitude dependencies were found to dier in the dusk and dawn sectors with a factor of two increase in the expansion of the duskside polar cap radius and auroral region over the dawnside. Additionally, the low-Kp polar cap radius was found to be five degrees smaller than the radius currently used in simple ionospheric models.

description: In this work an extended elliptic function method is proposed and applied to the generalized shallow water wave equation. We systematically investigate to classify new exact travelling wave solutions expressible in terms of quasi-periodic elliptic integral function and doubly-periodic Jacobian elliptic functions. The derived new solutions include rational, periodic, singular and solitary wave solutions. An interesting comparison with the canonical procedure is provided. In some cases the obtained elliptic solution has singularity at certain region in the whole space. For such solutions we have computed the effective region where the obtained solution is free from such a singularity.

description: International healthcare providers and institutions have shown little success in reducing AE rates by implementing large-scale evidence-based patient safety initiatives. In Ireland, the first Irish National Adverse Event Study (INAES) reported the AE rates in Irish hospitals to be 12.2.% (95% CI = 9.5% to 15.5%). This thesis examined the impact of recently implemented patient safety initiatives on the Irish healthcare system by comparing overall adverse event rates and preventable adverse event rates in Irish hospital inpatients between 2009 and 2015.1605 admissions were reviewed after random selection from 8 hospitals in Ireland using the Harvard Medical Practise Study methodology of chart review. The adverse event prevalence for 2015 was 14% (95% CI = 10.4% – 18.4%), a non-statistically significant increase from 12.2% (95% CI = 9.5% – 15.5%), (p = 0.48) in 2009. The incidence density in 2015 was 10.4 events per 100 admissions (95% CI = 6.5 – 14.3), a non-statistically significant increase from 10.3 events per 100 admissions (95% CI = 7.2 to 13.4), (p =0.97) in 2009. The proportion of preventable adverse events was 7.4% (95% CI = 5.3% -10.5%) in 2015 and 9.1% (95% CI = 6.9%-11.9%), (p=0.33) in 2009. The incidence density of preventable adverse events was 5.6 (95% CI = 3.4-8 ) events per 100 admissions in 2015 and 7.7 (95% CI = 5.8-9.6), (p=0.23) events per 100 admissions in 2009. We subcategorised adverse events into groups which we thought would reflect changes made by patient safety initiatives.It is possible that the downward trend seen in adverse events in the subcategories of adverse events represents a positive impact on patient care by the patient safety initiatives. This thesis highlights that adverse events remain a significant risk to patient safety in the Irish healthcare service requiring ongoing evidence-based approaches to remedy.
title: Parameterized Least-Squares Attitude History Estimation and Magnetic Field Observations of the Auroral Spatial Structures Probe
Creators: name: Martineau, Ryan J.
Publisher: name: Utah State University
Year: 2015

description: Terrestrial auroras are visible-light events caused by charged particles trapped by the Earth's magnetic eld precipitating into the atmosphere along magnetic eld lines near the poles. Auroral events are very dynamic, changing rapidly in time and across large spatial scales. Better knowledge of the low of energy during an aurora will improve understanding of the heating processes in the atmosphere during geomagnetic and solar storms.
The Auroral Spatial Structures Probe is a sounding rocket campaign to observe the middle-atmosphere plasma and electromagnetic environment during an auroral event with multipoint simultaneous measurements for fine temporal and spatial resolution. The auroral event in question occurred on January 28, 2015, with liftoff the rocket at 10:41:01 UTC. The goal of this thesis is to produce clear observations of the magnetic eld that may be used to model the current systems of the auroral event. To achieve this, the attitude of ASSP's 7 independent payloads must be estimated, and a new attitude determination method is attempted. The new solution uses nonlinear least-squares parameter estimation with a rigid-body dynamics simulation to determine attitude with an estimated accuracy of a few degrees. Observed magnetic eld perturbations found using the new attitude solution are presented, where structures of the perturbations are consistent with previous observations and electromagnetic theory.

description: A finite size effect in the probing of the harmonic measure in simulation of diffusion-limited aggregation (DLA) growth is investigated. We introduce a variable size of probe particles, to estimate harmonic measure and extract the fractal dimension of DLA clusters taking two limits, of vanishingly small probe particle size and of infinitely large size of a DLA cluster. We generate 1000 DLA clusters consisting of 50 million particles each, using an off-lattice killing-free algorithm developed in the early work. The introduced method leads to unprecedented accuracy in the estimation of the fractal dimension. We discuss the variation of the probability distribution function with the size of probing particles.
Vibration analysis of dry sand models

description: Using the shaking table, two types of tests have been made with 8 feet long by 1-1/2 feet wide and from 1/2 foot to 1 foot high dry Wedson sand models. One of them was a response study of the horizontal model, from which the affects of boundary restraints, the frequency-response of soil layer and the dynamic properties of dry sand were studied. The measured results with regard to the effects of boundary restraints and the frequency response of soil layer agreed with predictions by the linear visco-elastic theory. The measured shear wave moduli and damping ratio also agreed, with those obtained by previous workers. The other type of tests performed was a study of slope stability using tilted models, in which the accumulative displacement of slope was induced, by a sinusoidal base motion, the critical slope angle and the stable slope angle were studied. The measured accumulative displacement agreed with the theory suggested by Goodman and Seed (1966). It has been found that there are two distinctly different characteristic angles of slope associated with dynamic stability for a slope. These are the critical slope angle and the stable slope angle. Moreover, the stable slope angle is unique for a material and a frequency of the sinusoidal base motion and independent of the initial condition of the slope.

description: We study the quasinormal modes of the massless scalar perturbation in the background of a deformed black hole in the Hořava-Lifshitz gravity with coupling constant $λ=1$. Our results show that the quasinormal frequencies depend on the parameter in the Hořava-Lifshitz gravity and the behavior of the quasinormal modes is different from those in the Reissner-Norstr\"{om} and Einstein-Born-Infeld black hole spacetimes. The absolute value of imaginary parts is smaller and the scalar perturbations decay more slowly in the deformed Hořava-Lifshitz black hole spacetime. This information can help us understand more about the Hořava-Lifshitz gravity.

title: A Feminist Examination of How Girls and Women Engage with a Female Protagonist in Dystopian Young Adult Literature
Creators: name: Parent, Robin A.
Publisher: name: Utah State University
Year: 2015

description: This qualitative research study used a theoretical framework of third-wave feminism and reader response theory to examine two research questions: How do girls and women relate to the female protagonist in dystopian young adult literature (YAL)? and How are the responses to dystopian YAL similar and different for the targeted teen audience and the adult audience? A group of four teenaged girls and another group of three adult women read and discussed the YAL dystopian text Uglies. For this project, I collected participant journals and transcripts from individual interviews and book club discussions. I selected quotations from each data source that highlighted the participant’s reactions to the protagonist.
Data were analyzed in two phases. In phase one, I used discourse analysis, and in phase two I used constant comparative analysis. The analyses revealed that participants from both groups identified with the protagonist’s attempts to improve society, which aligns both groups’ responses with inclusive aspects of third-wave feminism. However, other aspects of feminism were incorporated into their answers as well. The women participants demonstrated a broader societal concern, such as those shared by second wave feminists. The girls, in contrast, were firmly situated within individualist aspects of third-wave feminism. Whereas, the women related to the protagonist on both a personal and broader societal level, the girls related only on a personal level. Findings from this research extend reader response theory by showing that responses to literature are strongly shaped by generational position.

description: Lorentz violation (LV) is predicted by some quantum gravity theories, where photon dispersion relation is modified, and the speed of light becomes energy-dependent. Consequently, it results in a tiny time delay between high energy photons and low energy ones. Very high energy (VHE) photon emissions from cosmological distance can amplify these tiny LV effects into observable quantities. Here we analyze four VHE $γ$-ray bursts (GRBs) from Fermi observations, and briefly review the constraints from three TeV flares of active galactic nuclei (AGNs) as well. One step further, we present a first robust analysis of VHE GRBs taking the intrinsic time lag caused by sources into account, and give an estimate to quantum gravity energy $\sim 2 \times 10^{17}$ GeV for linear energy dependence, and $\sim 5 \times 10^9$ GeV for quadratic dependence. However, the statistics is not sufficient due to the lack of data, and further observational results are desired to constrain LV effects better.

description: The fields in multiple-pass interferometers, such as the Fabry--Pérot cavity, exhibit great sensitivity not only to the presence but also to the motion of any scattering object within the optical path. We consider the general case of an interferometer comprising an arbitrary configuration of generic `beam splitters' and calculate the velocity-dependent radiation field and the light force exerted on a moving scatterer. We find that a simple configuration, in which the scatterer interacts with an optical resonator from which it is spatially separated, can also significantly enhance the optomechanical friction.

description: We study black holes in the Hořava-Lifshitz gravity with a parameter $λ$. For $1/3 \le λ< 3$, the black holes behave the Lifshitz black holes with dynamical exponent $0 < z \le 4$, while for $λ> 3$, the black holes behave the Reissner-Nordström type black hole in asymptotically flat spacetimes. Hence, these all are quite different from the Schwarzschild-AdS black hole of Einstein gravity. The temperature, mass, entropy, and heat capacity are derived for investigating thermodynamic properties of these black holes.

description: In recent years, deep neural networks for strategy games have made significant progress. AlphaZero-like frameworks which combine Monte-Carlo tree search with reinforcement learning have been successfully applied to numerous games with perfect information. However, they have not been developed for domains where uncertainty and unknowns abound, and are therefore often considered unsuitable due to imperfect observations. Here, we challenge this view and argue that they are a viable alternative for games with imperfect information — a domain currently dominated by heuristic approaches or methods explicitly designed for hidden information, such as oracle-based techniques. To this end, we introduce a novel algorithm based solely on reinforcement learning, called AlphaZe∗∗, which is an AlphaZero-based framework for games with imperfect information. We examine its learning convergence on the games Stratego and DarkHex and show that it is a surprisingly strong baseline, while using a model-based approach: it achieves similar win rates against other Stratego bots like Pipeline Policy Space Response Oracle (P2SRO), while not winning in direct comparison against P2SRO or reaching the much stronger numbers of DeepNash. Compared to heuristics and oracle-based approaches, AlphaZe∗∗ can easily deal with rule changes, e.g., when more information than usual is given, and drastically outperforms other approaches in this respect.
title: The Onion Name System: Tor-Powered Distributed DNS for Tor Hidden Services
Creators: name: Victors, Jesse
Publisher: name: Utah State University

description: Tor hidden services are anonymous servers of unknown location and ownership who can be accessed through any Tor-enabled web browser. They have gained popularity over the years, but still suer from major usability challenges due to their cryptographicallygenerated non-memorable addresses. In response to this difficulty, in this work we introduce the Onion Name System (OnioNS), a privacy-enhanced distributed DNS that allows users to reference a hidden service by a meaningful globally-unique veriable domain name chosen by the hidden service operator. We introduce a new distributed self-healing public ledger and construct OnioNS as an optional backwards-compatible plugin for Tor on top of existing hidden service infrastructure. We simplify our design and threat model by embedding OnioNS within the Tor network and provide mechanisms for authenticated denial-of-existence with minimal networking costs. Our reference implementation demonstrates that OnioNS successfully addresses the major usability issue that has been with Tor hidden services since their introduction in 2002.

title: Anaerobic Co-Digestion of Algal Biomass and a Supplemental Carbon Source Material to Produce Methane
Creators: name: Soboh, Yousef
Publisher: name: Utah State University
Year: 2015

description: Algae that are grown in wastewater treatment lagoons could be an important substrate for biofuel production; however, the low C/N ratio of algae is not conducive to anaerobic digestion of algae with economically attractive methane production rates. Increasing the C/N ratio in anaerobic, laboratory scale, batch reactors by blending algal biomass with sodium acetate resulted i increased methane production rates as the C/N ratio increased. The highest amount of methane was produced when the C/N was 21/1. When the C/N was 24/1, the biogas production rate decreased. Batch experiments were done to evaluate the effect of optimizing the C/N ratio on methane production from algae and to identify the most essential information needed to conduct research on co-digestion of algal biomass using the continuous, high-rate, up-flow anaerobic sludge blanket (UASB) reactor system. Based on the results obtained from batch reactor experiments, anaerobic co-digestion of algal biomass, obtained by continuous centrifugation from the Logan City, Utah, 5th stage wastewater treatment lagoon, and sodium acetate was conducted using laboratory scale UASB reactors with the C/N ratio in the feedstock adjusted to 21/1. Duplicate, 34 L UASB reactor systems were built of poly(methyl methacrylate). Both reactors were seeded with 11 L of anaerobic sediment from the 3rd stage lagoon. The pH of the feedstock was adjusted to the neutral range. The feedstock was initially introduced at a low organic loading rate of 0.9 g/L.d with a hydraulic retention time (HRT) of 7.2 days and then increased up to 5.4 g/L.d and a HRT of 5.5 days. These organic loading rates corresponded to an initial influent chemical oxygen demand (COD) of 6.25 g/L and increased to 27.2 g/L. Methane production increased from 270 mL/g to 349 mL/g COD biodegraded. COD removal efficiency was 80% and biogas methane composition was 90% at steady state. Algal biomass contributed 33-50% of the COD in the feed stock depending on the COD of the algae paste from centrifugation. The shortest HRT at which steady state was not affected was 5.5 days. At lower HRT all monitored parameters showed a slight decrease after the 75th day of operation.

description: Rabbits and hares, both popularly referred to as rabbits, occupy a very prominent position in the wildlife of Utah. Over much of the state, they form the most conspicuous faunal group, and between the lowest portion of the state to above timberline on the highest mountains there are very few areas entirely devoid or their presence. There is great variation, however, in their abundance, both between localities and times. In some areas, rabbit populations often attain amazingly high numbers to the delight of sportsmen and the dismay of farmers.

Creators: name: Riley, Theo A.
Publisher: name: Utah State University
Year: 1984

description: A predicted association between family relations and cognitive development and the emergence of adolescent egocentrism was explored in this study. A sample of seventh grade boys (n=131) and girls (n=120) completed Elkind and Bowen's Imaginary Audience Scale (a measure of egocentrism) and selected items from Heilbrun's Parent-Child Interaction Rating Scale and Schaefer's Parent-Behavior Inventory. A modified version of Lawson's Classroom Test of Formal Operations was used to measure cognitive development. Contrary to a theoretical based hypothesis a negative rather than positive relationship was found between level of formal operational thought egocentrism. For parenting style, perceived rejection/control and emotional support was associated with diminished egocentrism. Mixed results were found for perceived physical effect and egocentrism. Perceived parental withdrawal heightened egocentrism for both sexes. The data provide an alternative model to past cognitive development theory for the development of egocentrism. Parental socialization factors were found to contribute as much variance to the level of egocentrism as did level of formal operational thought.

The aim of this study was to evaluate how students respond to context-based vocabulary learning in Latin classes and whether they learn to transfer their language knowledge to other contexts. A key question of the still ongoing research project is: How can vocabulary competence in a historical language such as Latin be acquired and deepened by using corpus-based, i.e. context-based, methods? This question is based on a broad understanding of vocabulary that refers back to theories of the mental lexicon.

description: Alzheimer’s disease is a progressive disease that impairs cognitive and functional abilities. Currently, there is no cure and it is estimated there will be 81 million cases of Alzheimer’s disease by 2040. Life for the individual with Alzheimer’s disease, and their family, changes drastically when the affected individual experiences significant impairments in cognitive or functional ability (severe dementia), is placed in a skilled nursing home facility (institutionalization), or passes away (death). Until a cure is discovered, it will be important to identify modifiable factors that influence progression to severe dementia, institutionalization, and death. Three hundred thirty-five participants who were living in the community were followed after the onset of Alzheimer’s disease and continued until they left the study or the study period ended. Participants completed neuropsychological assessments at each visit. Visits occurred as close to every 6 months as possible and the mean number of visits was 5.32 (SD = 3.46). Outcomes of interest were severe dementia, institutionalization, and death. Predictor variables were hypertension, stroke, congestive heart failure, number of prescription medications being taken, General Medical Health Rating (GMHR) score, and Charlson Comorbidity Index score. Cox Regression was utilized to identify associations with progression to the specified outcomes. GMHR score, congestive heart failure, and number of prescription medications were associated with progression to severe dementia. The number of prescription medications was also associated with nursing home placement. GMHR score, stroke, and number of prescription medications were associated with death. These findings are important because they contribute to a better understanding of how measures of medical health, certain medical conditions, and potentially their prevention or treatment may help those with Alzheimer’s disease sustain a higher quality of life.
Pre- and Posttest of a Study on Latin Vocabulary Acquisition with Beginners (Textbook)
Creators: name: Beyer, Andrea
Publisher: name: Zenodo
Year: 2020
Subjects: Latin vocabulary learning
corpus-based learning
testing vocabulary competence
learning a historical language

description: Here, the test materials are released that were used in a third intervention study conducted over a period of one school year (2018-2019) in two 5th grades of a high-school in Berlin, Germany. The aim of this study was to evaluate how students respond to context-based vocabulary learning in Latin classes and whether they learn to transfer their language knowledge to other contexts. A key question of the still ongoing research project is: How can vocabulary competence in a historical language such as Latin be acquired and deepened by using corpus-based, i.e. context-based, methods? This question is based on a broad understanding of vocabulary that refers back to theories of the mental lexicon. Note: The English version offers just a translation of the work assignments. Since the reference language of the test is German both the text and all examples are not translated to keep the document as authentic as possible.

title: Optimization and Control of Lumped Transmitting Coil-Based In-Motion Wireless Power Transfer Systems
Creators: name: Hasan, Nazmul
Publisher: name: Utah State University

description: Wireless inductive power transfer systems are the only viable option for transferring energy to a moving vehicle. In recent years, there has been a great deal of interest in in-motion vehicle charging. The dominant technology thus far for in motion charging is elongated tracks, creating a constant eld for the moving vehicle. This technology suers from high volt ampere ratings and lower efficiency of 70%. On the other hand, stationary charging systems can demonstrate efficiency up to 95%. This thesis proposes lumped coils, similar to stationary charging coils for in-motion electric vehicle charging application. This novel primary coil architecture introduces new challenges in optimization and control. Traditional design of wireless inductive power transfer systems require designer experience, use of time consuming 3D FEM algorithms and lacks the comprehensive nature required for these systems. This thesis proposes two new optimization algorithms for the design problem which are comprehensive, based on only analytical formulations and do not need designer experience. There are challenges in the control of power transfer as well. Higher efficiency comparable to stationary systems can only be realized with proper synchronization of primary voltage with the vehicle position. Vehicle position detection and communication introduce significant cost and convenience issues. This thesis proposes a novel control algorithm which eliminates the need for vehicle position sensing and yet transfers the required percentage of energy. Both the optimization and control algorithms are verified with hardware setup.
Higher neutrino mass allowed if Cold Dark Matter and Dark Energy are coupled

description: Cosmological limits on neutrino masses are softened, by more than a factor 2, if Cold Dark Matter (CDM) and Dark Energy (DE) are coupled. In turn, a neutrino mass yielding $Ω_ν$ up to $\sim0.20$ allows coupling levels $β\simeq 0.15, $ or more, already easing the coincidence problem. The coupling, in fact, displaces both $P(k)$ and $C_l$ spectra in a fashion opposite to neutrino mass. Estimates are obtained through a Fisher--matrix technique.

Latin vocabulary acquisition

description: Here, the test materials are released that were used in the second intervention study conducted over a period of 6 to 8 weeks in two high-schools in Berlin, Germany (2018, 2019). The aim of this study was to evaluate how students in Latin classes in Germany deal with their vocabulary knowledge and whether they consider the context of words. A key question of the still ongoing research project is: How can vocabulary competence in a historical language such as Latin be acquired and deepened by using corpus-based, i.e. context-based, methods? This question is based on a broad understanding of vocabulary that refers back to theories of the mental lexicon. Note: Because of the context-based questions pretest and posttest differ in the selected myth, but not in the given tasks.

The stagnation point von Kármán coefficient

description: On the basis of various DNS of turbulent channel flows the following picture is proposed. (i) At a height y from the y = 0 wall, the Taylor microscale λis proportional to the average distance l_s between stagnation points of the fluctuating velocity field, i.e. λ(y) = B_1 l_s(y) with B_1 constant, for δ_ν<< y \lesssim δ. (ii) The number density n_s of stagnation points varies with height according to n_s = C_s y_+^{-1} / δ_ν^3 where C_s is constant in the range δ_ν<< y \lesssim δ. (iii) In that same range, the kinetic energy dissipation rate per unit mass, ε= 2/3 E_+ u_τ^3 / (κ_s y) where E_+ is the total kinetic energy per unit mass normalised by u_τ^2 and κ_s = B_1^2 / C_s is the stagnation point von Kármán coefficient. (iv) In the limit of exceedingly large Re_τ, large enough for the production to balance dissipation locally and for - ~ u_τ^2 in the range δ_ν<< y << δ, dU_+/dy ~ 2/3 E_+/(κ_s y) in that same range. (v) The von Kármán coefficient κis a meaningful and well-defined coefficient and the log-law holds only if E_+ is independent of y_+ and Re_τin that range, in which case κ~ κ_s. The universality of κ_s = B_1^2 / C_s depends on the universality of the stagnation point structure of the turbulence via B_1 and C_s, which are conceivably not universal. (vi) DNS data of turbulent channel flows which include the highest currently available values of Re_τsuggest E_+ ~ 2/3 B_4 y_+^{-2/15} and dU_+/dy_+ ~ B_4/(κ_s) y_+^{-1 - 2/15} with B_4 independent of y in δ_ν<< y << δif the significant departure from - ~ u_τ^2 is taken into account.

title: Looking a Gift Horse in the Mouth: 2014 Farm Bill Insect and Disease Restoration Provision -- True Gift or False Hope?
Creators: name: Holmstead, Jamilee E.
Publisher: name: Utah State University
Year: 2015

description: Congress passed a revised Farm Bill in 2014 that amended the Healthy Forest Restoration Act (HFRA) to, hopefully, increase the speed with which natural resource issues could be addressed. Federal land management has often been condemned for being time-consuming and burdensome, chiefly in situations that require rapid response, such as insect disease and fire. The amendment in the 2014 Farm Bill is meant to address this concern. The amendment would allow for the insect and disease restoration projects on U.S.D.A. Forest Service land to fall under the National Environmental Policy Act (NEPA) as categorical exclusions, provided that collaboration occurs while creating and implementing the projects. This new provision could allow for the U.S.D.A. Forest service to create and implement restoration projects at a faster rate than ever before. Each state's Governor was required to nominate restoration lands in their National Forests. These Nominations ranged from very comprehensive to extremely ambiguous and from just a few acres to entire national forests. This research documents why there was variation in designation nominations and what potential benefit this new amendment could bring to future natural resource management.
Tre forme di malinconia Una ricognizione su figure di malinconici, a partire dall'Atlas Mnemosyne

description: This reasoned survey of melancholy images contained in the Atlas is followed by an in-depth analysis on the theme of “Three forms of melancholy: an interpretation, from the Bilderatlas and other images”. In fact, the figures with the hand-to-face posture that you encounter in the Atlas may be divided into three groups that we have distinguished in order to map out a diagram of the analysis: Melancholy I. ex acedia; Melancholy II. ex otio; Melancholy III ex maerore. The precariousness and permeability among these typings are highlighted by the overlay of the three inclinations − sloth, thought, pain – that are present in almost all melancholic figures, especially in figures that do not allow themselves to be framed in one of the predefined categories. The sequence of images, through the highlighting of kindred relationships and of ‘nerve connections’, then offers possible further articulations – further overlays – of the tripartite scheme. The examples are taken from images that are displayed in the Atlas as well as other sources, which the Atlas-machine comes to summon.
