title: The Case of Youth Gangs in the Mormon Cultural Region A Synthetic, Dialectical Theory of Social Problems: Bridging Social Constructionism and Objectivism
Creators: name: Higley, Ramona Avis Linville
Publisher: name: Utah State University
Year: 2003

description: This dissertation uses the case of youth gangs in the Mormon Cultural Region to present a synthetic, dialectical theory of social problems, bridging the perspectives of social constructionism and objectivism. The primary assertion of this dissertation is that communities use social problems as tools to establish and maintain social boundaries and to protect the core values and beliefs of the established communal order.
The case of youth gangs in Utah, core of the Mormon Cultural Region, demonstrates that both social problems and the organizations involved with social problems follow a natural-history cycle similar to that reported in social movement literature. Anti-gang organizations, youth gangs, and the gang movement all seem to change forms as they progress through this cycle. Further, the relationship between the claims-making and the ontological increase in social problems is dialectical.
title: Microscopic Modeling of Crowds Involving Individuals with Physical Disability: Exploring Social Force Interaction
Creators: name: Stuart, Daniel S.
Publisher: name: Utah State University
Year: 2015

description: It has been shown that nearly one quarter of a population is affected by a disability which influences their interaction with the built environments, other individuals, and evacuation policies inhibiting their exit ability during an emergency evacuation. It is predicted that the number of individuals with a disability is on the rise. In the 21st century alone, there have been hundreds of events attributed to stampede or crowd crush, natural disaster, political revolt, terrorism, and other related emergencies. With an increase in the world's population, understanding emergency evacuations and how to best apply them is of growing importance. While research has investigated how crowds interact and evacuate, very little has been investigated in the impacts of how the disabled change an evacuation. While there are some beginnings to affect modeling with heterogeneous behaviors of disabled, little has been known in the analysis of crowds involving individuals with disabilities. There is a need to understand and model such interaction and how it impacts crowd movement. This dissertation implements and develops a novel video tracking system to study heterogeneous crowds with individuals with disabilities towards conducting a large-scale crowd experiment. A large-scale crowd experiment is conducted and the results are analyzed through a developed analysis graphical user interface for use with crowd dynamics experts. Preliminary results of the large-scale crowd experiment demonstrate differences in the velocities and overtaking perception of various groups with disabilities composed of the visually impaired, individuals with motorized and non-motorized wheelchairs, individuals with roller walkers, and individuals with canes or other stamina impairments. This dissertation uses these results to present a hybrid Social Force model that can capture the overall overtake behavior of the empirical data from our crowd experiments. Finally, future research goals are discussed in the eventual development of a Mass Pedestrian Evacuation system for crowds with individuals with disabilities. Lessons from this dissertation are discussed towards goals of crowd control.
title: Cenozoic Tectonic and Paleogeographic Evolution of the Horse Prairie Half-graben, Southwest Montana
Creators: name: VanDenburg, Colby J.
Publisher: name: Utah State University
Year: 1997

description: The Horse Prairie basin (HPB) of southwestern Montana is a complex, east dipping half-graben that contains three angular unconformity-bounded sequences of Tertiary lacustrine, paludal, and fluvial sediments overlying middle Eocene volcanic rocks. The basin is near the eastern edge of the Cordilleran thrust belt, and represents the western half of a larger Paleogene rift basin. Geologic mapping within the Everson Creek and Bannock Pass 7.5 minute quadrangles indicates that five temporally and geometrically distinct episodes of extension characterize the late Mesozoic (?) to Cenozoic tectonic evolution of the upper HPB.
The first episode of extension occurred prior to emplacement of middle Eocene volcanic rocks on an enigmatic, low-angle, southeast-dipping fault. Pre-volcanic extension (?) may reflect gravitational collapse of the Sevier thrust belt beginning in the lateMesozoic. The second episode of extension occurred in middle Eocene time on northwestdipping syn-volcanic normal faults. Syn-volcanic faults can be attributed to extension of the Challis volcanic arc, and typically accommodate less than I km of dip-slip separation. The third generation of normal faulting occurred on the low-angle, south-southwest- and west-dipping Lemhi Pass and Maiden Peak fault systems, respectively. Slip may have initiated during the waning phases of Challis volcanism, but these late to post-volcanic normal faults probably reflect continued gravitational collapse of the Sevier thrust belt, because they generally parallel contractional structures in the region. Late to post-volcanic normal faults accommodate the bulk of extensional strain in the study area, and are responsible for the deposition and preservation of the majority of basin-fill deposits in the HPB. Two episodes of middle Miocene and younger extension also occur within the study area; however, structural and basin analysis indicates the HPB experienced only minor extension in the last 17 m.y.
Spatial and temporal relationships between magmatism and extension suggest that large magnitude extension in the HPB (episodes I and 3) was not associated with magmatism, and that extension in this portion of the Basin and Range province initiated due to gravitational instabilities imparted on the crust during the Sevier orogeny.

description: Focusing on the Denver and Rio Grande Western Railway from Grand Junction, Colorado to Green River, Utah, this study examines the working circumstances of nineteenth-century railroad laborers, the ecological limitations of the isolating desert where they worked, and their relations with railroad management and local communities. It begins by investigating the experiences of the railroad surveyors and construction laborers. The study then examines the experiences of workers' response to labor organization in the communities of Green River, Utah and Grand Junction, Colorado. The study identifies ecological changes spawned by the railroad and addresses issues of worker autonomy and labor organization in the American West in the late nineteenth century.
title: Quantifying the Lateral Bracing Provided by Standing Seam Roof Systems
Creators: name: Sorensen, Taylor J.
Publisher: name: Utah State University
Year: 2016

description: One of the major challenges of engineering is finding the proper balance between economical and safe. Currently engineers at Nucor Corporation have ignored the additional lateral bracing provided by standing seam roofing systems to joists because of the lack of methods available to quantify the amount of bracing provided. Based on the results of testing performed herein, this bracing is significant, potentially resulting in excessively conservative designs and unnecessary costs.
This project performed 26 tests with Vulcraft joists in a pressure box to investigate the effects of how many variables influence the lateral bracing provided to joists from standing seam roofing systems, including the variables joist length, panel gauge, clip height, thermal block presence, insulation thickness, and top chord size. Two methods were developed to account for this additional bracing: finite element computer modeling and an application of the Rayleigh-Ritz method called the Column-on-Elastic-Foundation Method.
Variables influencing the pressure at failure, namely chord size and deck gauge, were those with the greatest effect on additional lateral bracing provided from standing seam roof systems. It was determined that higher roof stiffness values and higher failure pressures yield shorter effective lengths.

description: Rotating black holes in de Sitter space are known to have interesting limits where the temperatures of the black hole and cosmological horizon are equal. We give a complete description of the thermal phase structure of all allowed rotating black hole configurations. Only one configuration, the rotating Nariai limit, has the black hole and cosmological horizons both in thermal and rotational equilibrium, in that both the temperatures and angular velocities of the two horizons coincide. The thermal evolution of the spacetime is shown to lead to the pure de Sitter spacetime, which is the most entropic configuration. We then provide a comprehensive study of the wave equation for a massless scalar in the rotating Nariai geometry. The absorption cross section at the black hole horizon is computed and a condition is found for when the scattering becomes superradiant. The boundary-to-boundary correlators at finite temperature are computed at future infinity. The quasinormal modes are obtained in explicit form. Finally, we obtain an expression for the expectation value of the number of particles produced at future infinity starting from a vacuum state with no incoming particles at past infinity. Some of our results are used to provide further evidence for a recent holographic proposal between the rotating Nariai geometry and a two-dimensional conformal field theory.

description: At the center of the Milky Way, with a distance of ~8 kpc, the compact source Sagittarius A* (SgrA*) can be associated with a super massive black hole of ~4x10^6 solar masses. SgrA* shows strong variability from the radio to the X-ray wavelength domains. Here we report on simultaneous NIR/sub-millimeter/X-ray observations from May 2007 that involved the NACO adaptive optics (AO) instrument at the European Southern Observatory's Very Large Telescope, the Australian Telescope Compact Array (ATCA), the US mm-array CARMA, the IRAM 30m mm-telescope, and other telescopes. We concentrate on the time series of mm/sub-mm data from CARMA, ATCA, and the MAMBO bolometer at the IRAM 30m telescope.

description: Recent surveys seem to support bulk peculiar velocities well in excess of those anticipated by the standard cosmological model. In view of these results, we consider here some of the theoretical implications of large-scale drift motions. We find that observers with small, but finite, peculiar velocities have generally different expansion rates than the smooth Hubble flow. In particular, it is possible for observers with larger than the average volume expansion at their location, to experience apparently accelerated expansion when the universe is actually decelerating. Analogous results have been reported in studies of inhomogeneous (nonlinear) cosmologies and within the context of the Lemaitre-Tolman-Bondi models. Here, they are obtained within the linear regime of a perturbed, dust-dominated Friedmann-Robertson-Walker cosmology.

description: 1. AbstractIt is important for having early prediction of yield of crop. There are many countries in the world which uses conventional technique of crop production estimation using regular field visit and reports which in fact is expensive and less efficient. Now a day’s empirical data are popular but problematic and complex and using this information are available very late so is less efficient.Concerning with these problems efforts are being applied to increase accuracy of productionestimation. Satellite data are nowadays popular. NDVI based on satellite (remote sensed) and rice yield’s relationship is the topic for study at current situation.At field level, data was collected with the help of farmers based on management practices and production. Tables, spreadsheet data and shape files were created during field visit which helped for my study. Yield was related with the management and land factors with the help of powerful mathematical tool called Stepwise Backward Regression. I am using different parameters(manure) for estimation of crops growth i.e. Organic manure, Urea, Zinc, Potash, DAP etc.Although it’s use is boon for farmer at current situation but concerning on its long term effect is really unacceptable. The quality of soil is decreasing day by day and its acidity is increasing which has affected the health of consumers.

title: Benefits, Challenges, and Recommendations for Implementing a Sustainability-Based Service-Learning Program at Utah State University: An Initial Assessment of the Community Bridge Initiative
Creators: name: Koldewyn, Julie
Publisher: name: Utah State University

description: As communities continue to face issues relating to sustainability and with students demanding more university courses focused on solving these issues, a program that works to address both factors could prove beneficial. Modeled after the University of Oregon’s Sustainable Cities Initiative, the Community Bridge Initiative (CBI) at Utah State University aims to tackle specific community sustainability concerns by enlisting student and faculty expertise to create innovative ideas and provide increased capacity. While CBI is still in its pilot year, this thesis identified the benefits and challenges associated with the application of this program and provided recommendations to best implement this program once it leaves the pilot stage. Data were collected from a community needs assessment and from students enrolled in CBI pilot classes. The community needs assessment revealed that of 35 local organizations surveyed, 91% wanted to partner with USU in efforts to address current and future issues, showing that CBI would have the needed community support should it choose to partner with local organizations on various issues. Organization needs included improving the communities of Cache Valley, educating the public about important issues and spreading awareness of their specific programs, and mitigating funding and physical resource issues. For partnerships, organizations were most interested in pairing with USU on education and volunteer initiatives and sustainability-based efforts. In regard to students enrolled in CBI courses, the program also gained student validation as 92% of the students reported that the class positively impacted them, 88% would take a CBI course again, 63% would list the experience on their resume, and 73% felt that the class was more effective in communicating course content in comparison to traditional USU courses. Following these results, full implementation of the CBI program at Utah State University is recommended.

description: We study the artificial molecular states formed in laterally coupled double semiconductor nanorings by systems containing one, two and three electrons. An interplay of the interring tunneling and the electron-electron interaction is described and its consequences for the magnetization and charging properties of the system are determined. It is shown that both the magnetic dipole moment generated by the double ring structure and the chemical potential of the system as function of the external magnetic field strongly depend on the number of electrons and the interring barrier thickness. Both the magnetization and chemical potentials exhibit cusps at the magnetic fields inducing ground-state parity and / or spin transformations. The symmetry transformations are discussed for various tunnel coupling strengths: from rings coupled only electrostatically to the limit of coalesced rings. We find that in the ground-states for rings of different radii the magnetic field transfers the electron charge from one ring to the other. The calculations are performed with the configuration interaction method based on an approach of Gaussian functions centered on a rectangular array of points covering the studied structure. Electron-electron correlation is also discussed.

description: We consider the problem of option pricing under stochastic volatility models, focusing on the linear approximation of the two processes known as exponential Ornstein-Uhlenbeck and Stein-Stein. Indeed, we show they admit the same limit dynamics in the regime of low fluctuations of the volatility process, under which we derive the exact expression of the characteristic function associated to the risk neutral probability density. This expression allows us to compute option prices exploiting a formula derived by Lewis and Lipton. We analyze in detail the case of Plain Vanilla calls, being liquid instruments for which reliable implied volatility surfaces are available. We also compute the analytical expressions of the first four cumulants, that are crucial to implement a simple two steps calibration procedure. It has been tested against a data set of options traded on the Milan Stock Exchange. The data analysis that we present reveals a good fit with the market implied surfaces and corroborates the accuracy of the linear approximation.

title: Perceived Alzheimer's Disease Threat as a Predictor of Behavior Change to Lower Disease Risk: The Gray Matters Study
Creators: name: Clark, Christine
Publisher: name: Utah State University
Year: 2016

description: Alzheimer’s disease is a growing public health concern with the current number afflicted of 5 million in the US expected to triple by 2050. Since there is currently no cure or preventive pharmacological treatment, AD prevention research is now recognized as an important enterprise, with a goal to identify modifiable lifestyle factors that can reduce AD risk or delay its onset. Among these, increased physical activity, healthier food choices, more cognitive stimulation, better sleep quality, stress management, and social engagement have been identified as reasonable targets for behavioral intervention. A smartphone application-based behavioral intervention targeting these six behavioral domains was recently developed and a six-month randomized controlled trial was conducted, both to determine feasibility and compliance with technology usage and to test its efficacy. This study, titled the Gray Matters Study, was conducted in Cache County, Utah, enrolling a sample of 146 middle-aged participants (aged 40 to 64 years) randomized to treatment or control condition. Under the Health Belief Model, individuals who perceive a greater susceptibility to a particular health condition are hypothesized to be more likely to engage in more positive behaviors to reduce disease risk. Following this model, perceived threat of AD (operationalized by fear of AD, family history of AD, and metacognitive concerns) was examined for prediction of behavioral change over the six-month Gray Matters intervention period in these same six behavioral domains. Persons with a moderate level of fear of AD made significantly greater improvements in physical activity than those with low or high levels of fear. Family history was not a significant predictor of health-related behavioral change. However, persons with a moderate level of metacognitive concerns made significantly greater improvements in both physical activity and food quality than those with low or high levels of concerns. This is the first study to examine these psychological constructs related to AD risk and the extent to which they predict health-related behavior change. Future studies should extend the length of follow-up to at least one full year, include a more diverse sample of participants to expand generalizability, and build upon these findings to personalize supportive behavioral change interventions in order to be sensitive to these psychological factors.
title: Blind Front-end Processing of Dynamic Multi-channel Wideband Signals
Creators: name: Jackson, Kevin
Publisher: name: Utah State University
Year: 2016

description: In wireless digital communications, the sender and receiver typically know the modulation scheme with which they will be communicating. Automatic modulation identification is the ability to identify the modulation in a communication system with little to no prior knowledge of the modulation scheme. Many techniques for modulation identification operate on many assumptions including that the input signal is base-banded, the carrier frequency is known and that the signal is narrow-band (i.e. neighboring signals in the wide-band are excluded). This work provides the blind processing of an arbitrary wide-band signal to allow such assumptions. The challenges of such a front-end or pre-processor include detecting signals which can appear at any frequency, with any band-width at any given time and for any arbitrary duration. This work takes as its input a wide-band signal with a random number of sub-signals, each turning on and o at random times and each at random locations in the frequency domain. The output of the system is a collection of signals corresponding to each sub-signal brought down to base-band, isolated in the frequency and time domains, nominally sampled and with estimates of key parameters.
Dark Matter Decaying into a Fermi Sea of Neutrinos

description: We study the possible decay of a coherently oscillating scalar field, interpreted as dark matter, into light fermions. Specifically, we consider a scalar field with sub-eV mass decaying into a Fermi sea of neutrinos. We recognize the similarity between our scenario and inflationary preheating where a coherently oscillating scalar field decays into standard model particles. Like the case of fermionic preheating, we find that Pauli blocking controls the dark matter decay into the neutrino sea. The radius of the Fermi sphere depends on the expansion of the universe leading to a time varying equation of state of dark matter. This makes the scenario very rich and we show that the decay rate might be different at different cosmological epochs. We categorize this in two interesting regimes and then study the cosmological perturbations to find the impact on structure formation. We find that the decay may help alleviating some of the standard problems related to cold dark matter.

Study of equilibrium in exchange between HC1 gas and a KBr surface
Creators: name: Koga, Yoshikata
Publisher: name: University of British Columbia
Year: 2011

description: In the main part of this work, an equilibrium in anion exchange between HC1 gas and vacuum-sublimed KBr powder has been studied from 0° to 87°C. For total amounts of exchange corresponding to less than one surface layer, the equilibrium isotherms could be represented by a very simple empirical equation of the form, 1/R[subscript p]X = 1/R[subscript p]X[subscript m] + 1/K'Xm', --------------------------------(1) where X = amount exchanged normalized to BET surface, Xm and Xm' are paramaters of exchange capacity with the same dimensions as X, K' = a dimensionless parameter related in some way to an equilibrium constant for exchange, and R[subscript p] = P[subscript HBr]/P[subscript HCI] in the gas phase at equilibrium. If Xm were independent of temperature and equal to unity or some whole number of layers, eq. (1) with Xm = Xm' would correspond to an ideal chemical equilibrium expression, K = R[subscript p] [x/(Xm - X)] --------------------------------(2). In practice Xm was found to be temperature-dependent (Xm[symbol omitted]exp(-4,600/RT)) and ranged 0.5 at 9.4°C to 3 at 87°C (rather scattered experimental points render the 0°C value uncertain). The quantity designated (K'Xm') in eq. (1) is obtained experimentally as a single constant, and its separation Into an equilibrium constant and an exchange capacity parameters depends on the interpretation of the results. (K' Xm') has approximately the same temperature dependence as Xm , but it is not clear in the first instance whether this is to be ascribed to K' or to Xm'. Various models are examined which may give rise to the above experimental results. Among them; (a) one in which co-operative interactions of first and second anion neighbours in a single layer are treated by a modified form of the quasi-chemical approximation seems to be able to explain isotherms for 0° and 9.4°C, (b) another in which three layers are taken into account in a simple manner is capable of explaining isotherms for 500 to 87°C. This latter is capable of explaining results at all temperatures if the correlation of BET surface with exchange capacity of one layer is assumed to be in error by a factor of ∼ 2 and the experimental isotherm for 0°C is discarded on the basis that plots according to eq. (1) are scattered. Alternatively, some combination of the models used in (a) and (b) would probably also account for the complete set of results. In part II of this work, the system in which the reaction 2IBr = I₂ + Br₂ and gas chromatographic separation of IBr, I₂ and Br₂ occur simultaneously on the column has been studied experimentally. Various methods of matching the experimental data by computation are discussed, and a computational method based on a "plate theory" model is found satisfactory.

description: Farmers and agriculturalists have in recent years become more conscious of the seriousness of the weed problems. The solution of this problem is obviously the development of more efficient and less costly methods of eradication. Most pernicious weeds are propagated vegetatively by means of underground parts in which reserve food is stored as a source of energy in tiding the plant over winter and initiating spring growth each year. In order to get at the behavior of these perennial parts, it is necessary to resort to a study of root reserves. This involves information not only on the composition of the roots but also as to the quantity of roots. Since it is impossible to harvest all the roots, sampling must be used to furnish an estimate of the total quantity.

description: We propose an improved photoassociation scheme to produce ultracold molecules in their vibronic ground state for the generic case where non-adiabatic effects facilitating transfer to deeply bound levels are absent. Formation of molecules is achieved by short laser pulses in a Raman-like pump-dump process where an additional near-infrared laser field couples the excited state to an auxiliary state. The coupling due to the additional field effectively changes the shape of the excited state potential and allows for efficient population transfer to low-lying vibrational levels of the electronic ground state. Repetition of many pump-dump sequences together with collisional relaxation allows for accumulation of molecules in v=0.

description: We use a method of linearization to study the emergence of the future cosmological singularity characterized by finite value of the cosmological radius. We uncover such singularities that keep Hubble parameter finite while making all higher derivatives of the scale factor (starting out from the $\ddot a$) diverge as the cosmological singularity is approached. Since such singularities has been obtained before in the brane world model we name them the "brane-like" singularities. These singularities can occur during the expanding phase in usual Friedmann universe filled with both a self-acting, minimally coupled scalar field and a homogeneous tachyon field. We discover a new type of finite-time, future singularity which is different from type I-IV cosmological singularities in that it has the scale factor, pressure and density finite and nonzero. The generalization of $w$-singularity is obtained as well.

description: It is not intended that this paper be an exhaustive study of journalism in the Utah high schools. It, is intended that it open up the field and perhaps point the way for further study. Very, little has been done, for instance, in the history of high school journalism in Utah. Very little has been done in this study on the appraisal of papers; only the most general observations have been made. A great deal has depended on the judgment of advisers, and advisers, like all other human beings, differ in point of view and understanding.

description: In an extension of the minimal supersymmetric standard model (popularly known as the $μν$SSM), three right handed neutrino superfields are introduced to solve the $μ$-problem and to accommodate the non-vanishing neutrino masses and mixing. Neutrino masses at the tree level are generated through $R-$parity violation and seesaw mechanism. We have analyzed the full effect of one-loop contributions to the neutrino mass matrix. We show that the current three flavour global neutrino data can be accommodated in the $μν$SSM, for both the tree level and one-loop corrected analyses. We find that it is relatively easier to accommodate the normal hierarchical mass pattern compared to the inverted hierarchical or quasi-degenerate case, when one-loop corrections are included.

title: Effects of a Self-Management Procedure Using Student Feedback on Staff Members' use of Praise in an Out-Of-School Time Program

description: Out-of-school time (OST) programs are under increasing pressure to improve student achievement. However, OST program administrators face a number of challenges to improving program effectiveness including inconsistent student participation, inexperienced staff members, and a lack of high-quality professional development. OST program administrators can address these challenges by implementing staff development practices that encourage the use of effective instructional strategies.
Specific praise is a simple and effective instructional strategy that has been linked to improved student engagement, enhanced academic achievement, and stronger student-teacher relationships. Unfortunately, there have been very few studies examining the effects of interventions designed to increase OST staff members’ use of specific praise. One staff development strategy that could be both feasible and effective is the use of self-management. Although there are a variety of approaches to self-management designed for teachers, not all self-management strategies are effective.
One strategy that might increase the feasibility and effectiveness of self-management programs is the use of student feedback. The process of comparing self-evaluations against a third-party standard such as student feedback is called matching in the self-management literature. Students can be a useful source of feedback because they observe their teachers frequently and can report the use of instructional strategies like specific praise. The purpose of this study was to examine the effects of a self-management procedure using student feedback on OST staff members’ use of specific praise. A multiple-baseline design across participants was used to examine the effects of the intervention on specific praise rates.
All participants increased their use of specific praise after implementing the self-management procedures. General praise rates became more variable throughout the study. These findings provide evidence for a functional effect on specific praise but not for general praise. Teachers reported high levels of satisfaction with the feasibility and effectiveness of the intervention. A statistically significant correlation was found between specific praise rates and student reports of specific praise.
title: Thermal Property Measurement of Thin Fibers by Complementary Methods

description: To improve measurement reliability and repeatability and resolve the orders of magnitude discrepancy between the two different measurements (via reduced model transient electrothermal and lock-in IR thermography), this dissertation details the development of three complementary methods to accurately measure the thermal properties of the natural and synthetic Nephila (N.) clavipes spider dragline fibers. The thermal conductivity and diffusivity of the dragline silk of the N. clavipes spider has been characterized by one research group to be 151-416 W m−1 K −1 and 6.4-12.3 ×10−5 m2 s −1 , respectively, for samples with low to high strains (zero to 19.7%). Thermal diffusivity of the dragline silk of a different spider species, Araneus diadematus, has been determined by another research group as 2 ×10−7 m2 s −1 for un-stretched silk. This dissertation seeks to resolve this discrepancy by three complementary methods. The methods detailed are the transient electrothermal technique (in both reduced and full model versions), the 3ω method (for both current and voltage sources), and the non-contact, photothermal, quantum-dot spectral shape-based fluorescence thermometry method. These methods were also validated with electrically conductive and non-conductive fibers. The resulting thermal conductivity of the dragline silk is 1.2 W m−1 K −1 , the thermal diffusivity is 6 ×10−7 m2 s −1 , and the volumetric heat capacity is 2000 kJ m−3 K −1 , with an uncertainty of about 12% for each property
Dipole Oscillations in Fermionic Mixtures

description: We study dipole oscillations in a general fermionic mixture: starting from the Boltzmann equation, we classify the different solutions in the parameter space through the number of real eigenvalues of the small oscillations matrix. We discuss how this number can be computed using the Sturm algorithm and its relation with the properties of the Laplace transform of the experimental quantities. After considering two components in harmonic potentials having different trapping frequencies, we study dipole oscillations in three-component mixtures. Explicit computations are done for realistic experimental setups using the classical Boltzmann equation without intra-species interactions. A brief discussion of the application of this classification to general collective oscillations is also presented.

Determining interaction rules in animal swarms

description: In this paper we introduce a method for determining local interaction rules in animal swarms. The method is based on the assumption that the behavior of individuals in a swarm can be treated as a set of mechanistic rules. The principal idea behind the technique is to vary parameters that define a set of hypothetical interactions to minimize the deviation between the forces estimated from observed animal trajectories and the forces resulting from the assumed rule set. We demonstrate the method by reconstructing the interaction rules from the trajectories produced by a computer simulation.

title: Staff Interactions and Affect in Persons with Dementia: an Observational Study of a Memory Care Unit

description: By the year 2050 it is expected that the number of older adults living with dementia will triple. With 42% of persons with dementia living in residential care, it is vital that we better understand how to maintain high psychosocial well-being for this population, in this setting. The objective of this study was to better understand psychosocial well-being in persons with dementia. The research team observed affect in clients with dementia (n = 22), as well as staff interactions with clients in a residential memory care unit for a total of 6999 minutes. The first purpose was to examine overall proportions of client affect and staff interaction types, both for the whole sample, and in more detail (assessing inter/intraindividual differences) for the five most observed clients. The second purpose was to identify whether proportions of positive affect in clients differed based on staff interaction type. The third purpose was to examine themes emerging from a review of field notes when staff interactions and/or client affect were noted. Analyses identified that the most observed affect type was neutral affect (53.1% of all minutes observed). The most common interaction type was neutral or no interaction (81.1% of all minutes observed). Positive affect accounted for 44.5% of observations, and positive staff interactions for 18.1% of the observations. There was very little negative affect (2.4%) and negative interactions (.8%) observed. When staff had neutral/no/negative interactions, clients were positive 36% of the time, whereas when staff had positive interactions, clients were positive 81% of the time (z = 28.84, p < .001). The review of the field notes identified themes and subthemes related to behavioral problems and other client problems, and the staff either responding to or ignoring these problems. The review also identified occasions when staff engaged clients beyond what was required of them. While quantitative analyses suggested low rates of negative staff interaction, the field notes highlight that sometimes no interaction (ignoring a client) is also problematic. This study suggests that positive social interactions between staff and clients may be important in maintaining positive affect and overall wellbeing in persons with dementia.

description: We give a new method for calculation of complex and biHermitian structures on low dimensional real Lie algebras. In this method, using non-coordinate basis, we first transform the Nijenhuis tensor field and biHermitian structure relations on Lie groups to the tensor relations on their Lie algebras. Then we use adjoint representation for writing these relations in the matrix form; in this manner by solving these matrix relations and using automorphism groups of four dimensional real Lie algebras we obtain and classify all complex and biHermitian structures on four dimensional real Lie algebras.
