title: Petrology of the Lower Middle Cambrian Langston Formation, North-central Utah and Southeastern Idaho
Creators: name: Butterbaugh, Gary Jay
Publisher: name: Utah State University
Year: 1982

description: The Lower Middle Cambrian Langson Formation was studied in the xi Bear River Range of north-central Utah and southeasternmost Idaho and the Wellsville Mountains of north-central Utah. The depositional textures and sedimentary structures preserved within the rocks were compared with characteristics of similar modern sediments and ancient rock to determine environments of deposition, paleogeography, diagenetic alteration and pattern of dolomitization.
The rocks of the Langston Formation were divided into eleven different rock types. These eleven rock types were formed within four recognizable lithofacies: 1) upper peritidal; 2) inner carbonate shelf; 3) inner clastic shelf; and 4) outer clastic shelf.
The general depositional environment is inferred to have been a shall ow subtidal to subaerial carbonate shoal complex. Clastic sediments from the east and north or northwest periodically prograded over the carbonate complex during times of relatively slow subsidence. The deposition of the Langston Formation mudrocks and carbonates occurred during the first Cambrian grand cycle.
Eogenetic diagenetic features include birdseye structures, relict evaporite structures, fibrous rim cement, compaction, and the begining of dolomitization. Mesogenetic diagenesis is characterized by dolomitization and pressure solution. Telogenetic diagenesis is limited to fracturing and calcite infilling.
Dolomitization is believed to have resulted mainly from downward reflux of hypersaline brines, as indicated by relict evaporite structures, zoned dolomite rhombs, and a general association of dolomite with upper peritidal facies. The hypersaline brines formed in the upper peritidal environment, and percolated downward through underlying porous sediments. The greater density of the hypersaline brines displaced less-dense interstitial fluids. These brines were periodically diluted by normal marine water or fresh water.

description: By using the backward fractional Fokker-Planck equation we investigate the barrier crossing event in the presence of Levy noise. After shortly review recent results obtained with different approaches on the time characteristics of the barrier crossing, we derive a general differential equation useful to calculate the nonlinear relaxation time. We obtain analytically the nonlinear relaxation time for free Levy flights and a closed expression in quadrature of the same characteristics for cubic potential.

Impact of Friction and Scale-Dependent Initial Stress on Radiated Energy-Moment Scaling
Creators: name: Shaw, Bruce E.
Publisher: name: Columbia University

Subjects: Plate tectonics
Physics

description: The radiated energy coming from an event depends on a number of factors, including the friction and, crucially, the initial stress. Thus we cannot deduce any scaling laws without considering initial stress. However, by simulating long sequences of events, where the system evolves to a statistically steady-state, we can obtain the appropriate distribution of initial stresses consistent with the dynamics and a given friction. We examine a variety of frictions, including power-law slip dependence, and explore a variety of scaling relations, with the aim of elucidating their radiated energy-moment scaling. We find, contrary to expectations, that apparent stress is not seen to increase with earthquake size for power-law weakening. For small and for large events, little change in apparent stress is seen with increasing rupture size, while intermediate sized events interpolate in between. We find the origin of this unexpected lack of size dependence in systematic changes of initial stress, with bigger events tending to sample regions of lower initial stress. To understand radiated energy-moment scaling, scale-dependent initial stress needs to be considered.
title: Petrology of the Middle Cambrian Langston and Ute Formations in Southeastern Idaho
Creators: name: Rogers, Daniel T.
Publisher: name: Utah State University
Year: 1987

description: The Middle Cambrian Langston and Ute formations were studied in the northern portion of the Bear River Range and the south-central part of the Portneuf Range in southeastern Idaho.
The rocks of the Langston and Ute formations were divided into 17 different rock types. The 17 rock types were formed within four recognizable lithofacies: I) Shoal - or Coastal -Peritidal Carbonate Complex; 2) Agitated Shoal; 3) Inner Marine Shelf; and 4) Outer Marine Shelf. Clastic sediments belonging to the Spence Shale Member of the Langston Formation (outer marine shelf) were deposited over the carbonate complex . A transgressive sequence marks the base of both formations.
Paleomagnetic evidence suggests that during the time of the deposition of the two formations, the study area was located near the outer reaches of an equatorial epeiric sea. Clay mineralogy of insoluble residues suggests a warm, humid, tropical climate.
Eogenetic diagenetic features include compaction, cementation, aggrading, and degrading neomorphism, birdseye structures, and initiation of dolomitization . Mesogenetic diagenetic features include dolomitization and pressure solution. Telogenetic diagenetic features are confined to fracturing and subsequent calcite infilling, and the oxidation of pyrite.
Massive dolomitization in the northernmost section is believed to be the result of a downward flux of fluids originating as hypersaline brines. The nonconformable lower contact, conformable upper contact, the vertical and lateral extent of dolomitization, and the general association with coastal-peritidal facies have led to this conclusion. Two other subordinate types of dolomite are believed to be the result of: 1) the release of magnesium caused by the decomposition of magnesium-rich organic matter; and 2) the formation of a secondary ferroan dolomite as Fe/Mg ratios in the precipitating fluids increased under reducing conditions.
Power & environmental policy : Tasmanian ecopolitics from Pedder to Wesley Vale
Creators: name: Crowley, Catherine M
Publisher: name: University Of Tasmania
Year: 2023

description: It is argued that the realisation of ecopolitical values, interests and demands is inevitably constrained by material interests within advanced industrial societies. The policy environment in the state of Tasmania is examined, and both a traditional affirmation and accommodation of the goals of industrial development, and a resistance to the more recent ecopolitical challenge to established state interests is found. However, a review of four key environmental disputes finds that the politics of ecology ('ecopolitics'), despite routine constraint by material interests, continues to defy predictions of its inevitable demise as a 'single issue', and continues to gain ground as an ideological force in Tasmania. In reviewing the capacity of environmentalists to realise their aims (i) the nature and significance of the ecopolitical challenge is considered; (ii) ideological contention as a constraint in the realisation of ecopolitical interests is examined; (iii) the limits of state response to ecopolitical demands are reviewed; (iv) the political expression of conflicting values over two decades of Tasmanian ecopolitical conflict are examined; and (v) the Tasmanian tradition of underwriting industrial development is found to have acted as a 'policy paradigm' confining state action on environmental issues. A policy based framework of analysis is adopted that acknowledges ideological, political and institutional constraints, and is informed by (i) ecopolitical theory, given the deficiencies of traditional policy analysis in capturing the nature of the ecopolitical challenge, and (ii) power analysis in addressing policy constraint. -This framework recognises ecopolitics as a struggle between value contenders, and ecopolitical demands as potentially limited by the constraining influence of dominant values and industrial interests. This framework is applied to analysis of the Lake Pedder, Franklin River, Electrona silicon smelter and Wesley Vale pulp mill disputes. These disputes are detailed in Chapter Four, then reviewed in Chapter Five in terms of the nature of the environmental values at stake, the accommodation or frustration of these values, and the actions of the state in resolving the disputes. Whilst the ecopolitical challenge is not found to have been contained in Tasmania, environmental demands are nevertheless found to have been constrained by material values, the accommodation of industrial interests, and the institutionalisation of the traditional pursuits of development and resource exploitation.

description: We present the data processing and analysis techniques we are using to determine structural and photometric properties of galaxies in our Gemini/HST Galaxy Cluster Project sample. The goal of this study is to understand cluster galaxy evolution in terms of scaling relations and structural properties of cluster galaxies at redshifts 0.15 < z < 1.0. To derive parameters such as total magnitude, half-light radius, effective surface brightness, and Sersic n, we fit r^{1/4} law and Sersic function 2-D surface brightness profiles to each of the galaxies in our sample. Using simulated galaxies, we test how the assumed profile affects the derived parameters and how the uncertainties affect our Fundamental Plane results. We find that while fitting galaxies which have Sersic index n < 4 with r^{1/4} law profiles systematically overestimates the galaxy radius and flux, the combination of profile parameters that enter the Fundamental Plane has uncertainties that are small. Average systematic offsets and associated random uncertainties in magnitude and log r_e for n > 2 galaxies fitted with r^{1/4} law profiles are -0.1+-0.3 and 0.1+-0.2 respectively. The combination of effective radius and surface brightness, log r_e - βlog _e, that enters the Fundamental Plane produces offsets smaller than -0.02+-0.10. This systematic error is insignificant and independent of galaxy magnitude or size. A catalog of photometry and surface brightness profile parameters is presented for three of the clusters in our sample, RX J0142.0+2131, RX J0152.7-1357, and RX J1226.9+3332 at redshifts 0.28, 0.83, and 0.89 respectively.

description: This paper deals with the physical and environmental effects resulting from oceanic impacts by sizable comets, and the rates and risks associated with such cosmic impacts. Specifically, we investigate two sets of probable oceanic impact events that occurred within the last 5,000 years, one in the Indian Ocean about 2800 BC, and the other in the Gulf of Carpentaria (Australia) about AD 536. If validated, they would be the most energetic natural catastrophes occurring during the middle-to-late Holocene with large-scale environmental and historical human effects and consequences. The physical evidence for these two impacts consists of several sets of data: (1) remarkable depositional traces of coastal flooding in dunes (chevron dunes) found in southern Madagascar and along the coast of the Gulf of Carpentaria, (2) the presence of crater candidates (29-km Burckle crater about 1,500 km southeast of Madagascar which dates to within the last 6,000 years and 18-km Kanmare and 12-km Tabban craters with an estimated age of AD 572±86 in the southeast corner of the Gulf of Carpentaria), and (3) the presence of quench textured magnetite spherules and nearly pure carbon spherules, teardrop-shaped tektites with trails of ablation, and vitreous material found by cutting-edge laboratory analytical techniques in the upper-most layer of core samples close to the crater candidates. Although some propose a wind-blown origin for V-shaped chevron dunes that are widely distributed around the coastlines of the Indian Ocean and in the Gulf of Carpentaria, we have evidence in favor of their mega tsunami formation. In southern Madagascar we have documented evidence for tsunami wave run-up reaching 205 m above sea-level and penetrating up to 45 km inland along the strike of the chevron axis. Subtly the orientation of the dunes is not aligned to the prevailing wind direction, but to the path of refracted mega-tsunami originating from Burckle impact crater. The results of our study show that substantive oceanic comet impacts not only have occurred more recently than modeled by astrophysicists, but also that they have profoundly affected Earth’s natural systems, climate, and human societies. If validated, they could potentially lead to a major paradigm shift in environmental science by recognizing the role of oceanic impacts in major climate downturns during the middle-to-late Holocene that have been well documented already by different techniques (tree-ring anomalies, ice-, lake- and peat bog-cores).

description: That the higher valleys of the Wasatch Mountains ere occupied by Pleistocene glaciers has long been known. King, Hague, and Emmons, geologists of the Fortieth Parallel Survey, the first to undertake a systematic study of any part of the Wasatch Mountains, recognized this fact and their report includes a map which shows 1n a rough ay the extent of the glaciated areas in the Central Wasatch (II) In 1909 Atwood (1) made a detailed study of the glacial features of the Central Wasatch in connection with his study of glaciation in the Uinta Mountains. He mapped the deposits of 2 distinct glacial ages, but did not consider any part of the range north of Salt Lake County. Recently Bradley(8) has discovered the deposits of a third and older glacial age in the Uinta mountains, thus indicating the possibility of a similar discovery in the Wasatch Mountains. Blackwelder (6) had previously recognized 3 glacial ages in the Wind River Mountains in western Wyoming and had made preliminary observations on glaciation in the Stansbury and Oquirrh ranges, Utah (7). While these studied have been completed tor the central part of the Wasatch Range and for surrounding regions, no description of the glacial geology of the Northern Wasatch has ever appeared.

Holomorphic Functions on Bundles Over Annuli

description: We consider a family E_m(D,M) of holomorphic bundles constructed as follows: to any given M in GL_n(Z), we associate a "multiplicative automorphism" f of (C*)^n. Now let D be a f-invariant Stein Reinhardt domain in (C*)^n. Then E_m(D,M) is defined as the flat bundle over the annulus of modulus m>0, with fiber D, and monodromy f. We show that the function theory on E_m(D,M) depends nontrivially on the parameters m, M and D. Our main result is that E_m(D,M) is Stein if and only if m log(r(M)) <= 2 π^2, where r(M) denotes the max of the spectral radii of M and its inverse. As corollaries, we: -- obtain a classification result for Reinhardt domains in all dimensions; -- establish a similarity between two known counterexamples to a question of J.-P. Serre; -- suggest a potential reformulation of a disproved conjecture of Siu Y.-T.

Influence of constant enthalpy on broiler growth rate
Creators: name: Kennedy, Brian James
Publisher: name: University of British Columbia
Year: 2011

description: An experiment was designed to test the hypothesis that enthalpy could be used as an indicator of the suitability of the environment for growing poultry. Growth-rates and body weights of the birds were used as a measure of their performance under different enthalpy conditions. The experiment tested three enthalpy treatments, ranging from 29.3 to 33.3 BTU/lb of air, each treatment being replicated three times. Male University of British Columbia New Hampshire chickens from nine hatches (120 birds per hatch) were used. They were grown from hatch to seven weeks of age in three groups. Two of the groups were raised from hatch to three weeks of age in controlled environment brooders. The third group was raised in a non-controlled environment in a floor pen, and used as a check or control group. The results of the analyses indicated that further study would be necessary before enthalpies in the range studied could be used to predict environmental conditions for poultry.

title: Origin and Evolution of Dolostone in the Middle Cambrian Langston Formation, Northern Utah
Creators: name: Hall, Mark C.
Publisher: name: Utah State University
Year: 1989

description: Six major generations of dolomite are present within the Cambrian Langston Formation in the Wellsville Mountains and Bear River Range of northern Utah. Identification of dolomite generations and delineation of their relative sequences are based on normal light petrography, cathodoluminescence, staining, chemistry, inferred burial history, and deformation features. The earliest stage is believed to be Middle to Late Cambrian in age. The presence of dolomite rhombs and dolomitized echinoid fragments and peloids suggests that this stage probably formed under sabkha reflux conditions. Extensive nonferroan, polymodal, nonplanar ("xenotopic") dolomite formed next under confined mixing zone conditions. A succeeding generation of pervasive ferroan, polymodal, nonplanar dolomite formed upon exposure to evolved confined mixing zone waters or fluids derived from basin compaction. Subsequent neomorphism of these two nonplanar stages to nonferroan and ferroan saddle dolomites occurred with increased burial. The final stage of dolomitization is confined to dolomite-filled veins and an orthodolospar probably fanned from fluids associated with Tertiary Basin and Range faulting. Thus, there are at least six major types of dolomite within the Langston Formation. Spatial distribution and intensity of the early-formed dolomite facies, as revealed by fence diagrams, are postulated to be functions of changes in permeability, hydrodynamic dispersion, water chemistry, and concomitant variations in length of the induction ix stages.
title: Footwall Deformation and Structural Analysis of the Footwall of the Willard Thrust Fault, Northern Wasatch Range, Utah
Creators: name: Neves, Douglas Scott
Publisher: name: Utah State University
Year: 1989

description: Deformation mechanisms in the footwall of the Willard thrust fault, northern Wasatch Range, Utah, change from dominantly plastic to dominantly cataclastic (both microscopically and macroscopically) in the Ophir Formation and Maxfield Limestone before the thrust begins to ramp laterally upsection southward, just to the north of the North Ogden Canyon field area. This transition in compressional deformation style and mechanism is located within a lateral distance of 3.2-kilometers along the 22-kilometer long trace of the thrust fault.
Between Willard Canyon and North Ogden Canyon penetrative deformation is localized within 200 meters of the thrust surface and is characterized by transposed bedding, solution cleavage parallel to bedding, a northeast- to northwest-dipping foliation, and tight isoclinal folds with axes plunging generally northward. A fracture overprint in the footwall is present throughout the study area. The transition in deformation mechanism and style suggests that footwall deformation is dependent on the sensitive response of limestone and shale to increased pressure and temperature conditions and also the presence of a lateral ramp in the footwall of the Willard thrust. Data from a hangingwall sequence diagram and a stratigraphic displacement diagram suggest the Taylor and Ogden thrusts formed prior to the Willard thrust (the roof thrust) and their sequential geometrical evolution may have been influenced by preexisting rifts in the underlying crystalline basement rock.
It is proposed that early Cretaceous movement of the Willard thrust sheet over the structurally lower and older Taylor and Ogden thrust sheets resulted in the formation of a recumbent syncline overturned to the east, a southward rising lateral ramp in the footwall of the Willard thrust, a lateral change in footwall deformation, and the anomalous east-west trending canyons that cut through the Willard thrust complex.

description: A number of spectacular experimental anomalies\cite{li-2007,fujita-2005} have recently been discovered in certain cuprates, notably {\LBCO} and {\LNSCO}, which exhibit unidirectional spin and charge order (known as ``stripe order''). We have recently proposed to interpret these observations as evidence for a novel ``striped superconducting'' state, in which the superconducting order parameter is modulated in space, such that its average is precisely zero. Here, we show that thermal melting of the striped superconducting state can lead to a number of unusual phases, of which the most novel is a charge $4e$ superconducting state, with a corresponding fractional flux quantum $hc/4e$. These are never-before observed states of matter, and ones, moreover, that cannot arise from the conventional Bardeen-Cooper-Schrieffer (BCS) mechanism. Thus, direct confirmation of their existence, even in a small subset of the cuprates, could have much broader implications for our understanding of high temperature superconductivity. We propose experiments to observe fractional flux quantization, which thereby could confirm the existence of these states.

description: I will not deny the quandary I find myself in when attempting to speculate on the nature of objects and their description. If I had a camera that could create images out of memory I would use it instead of drawing. Drawing can be clumsy and laboured or clinically correct and dispassionate or some how removed from the issues and concerns that are central to my way of making art. However, I will proceed as though the technology for this kind of photography does not exist. It is possibly the description of objects, that is, objects as physical matter, that confounds me most of all. My current practice is to describe objects by drawing and painting them in a variety of ways. Through drawing I hope to demonstrate my concerns with the general workings of memory and recall together with the specifics of some objects and events that have become permanently fixed in my mind, and regularly stimulate recollections of repressed experience (or what I perceive to be specifically repressed experiences). Drawing deals with the psychic mechanisms of the locus, the arbitrariness in choosing elements and their arrangements, in a cohesive way that always remains affective. Decisions concerning the composition of object images follow the rules of parataxis. That is, an arrangement of images and ropositions that allow the interconnections between images to be upplied by the mind of the viewer. The images themselves seem to have an equivalent status, they may appear as habitual. The images have no preordained function, they arrive at their place \out of the blue\". These images extracted from my imagination deal with memory recall recognition and their opposites forgetting repression and incomprehension. I am not just correcting personal prejudices connected to objects. By repeating images and text I hope to evoke moods and sensations by creating an illusion of the passage of time by images occurring and recurring within the work. The art work does not realise its true status by my simply reconstructing images from my past. But its status is improved by my engagement with the physical sensations and outward displays of temperament changes that memory produces at the time of making the art work."

title: Development of Cooperation Between Children in the Minimal Social Situation
Creators: name: Siegel, Janice V.
Publisher: name: Utah State University
Year: 1976

description: The purpose of this study was to determine whether children can learn to cooperate in what has been described as the "minimal social situation." The research also compared the effectiveness of verbal instructions and a training task for teaching subjects the "win-stay, lose-change" rule. This rule has been used to explain the development of cooperation in the minimal social situation.
Subjects were 19 teams of first-, second-, and third-graders. Five teams were composed of two girls; six were girl-boy teams; and eight were boy-boy teams. Ten of the 19 teams learned to cooperate in the minimal social situation without treatment. Two of four teams given the rule training procedure learned to cooperate after having failed to learn under typical minimal social conditions. Of five teams given verbal instructions, four learned to cooperate immediately.
The probability of following the win-stay, lose-change rule was approximately 50% initially and did not increase significantly in later sessions. It is not clear then that following this rule is a prerequisite for the development of a cooperative exchange. Explanations in the literature which suggest subjects learn a single rule, i.e., win-stay, lose-change, may be misleading since children evidenced a variety of rules, any of which might have been reinforced or punished over the course of the experiment.

Leptonic/hadronic models for electromagnetic emission in microquasars: the case of GX 339-4

description: We present a general self-consistent lepto/hadronic jet model for the non-thermal electromagnetic emission of microquasars. The model is applied to the low-mass microquasar (LMMQ) GX 339-4 and predicts its high-energy features. We assume that both leptons and hadrons are accelerated up to relativistic energies by diffusive shock acceleration, and calculate their contribution to the electromagnetic spectrum through all main radiative processes. The radiative contribution of secondary particles (pions, muons and electron-positron pairs) is included. We use a set of simultaneous observations in radio and X-rays to constrain the model parameters and find the best fit to the data. We obtain different spectral energy distributions that can explain the observations, and make predictions for the high-energy emission. Observations with gamma-ray instruments like Fermi can be used to test the model and determine the proton content of the jets. Finally, we estimate the positron injection in the surrounding medium. Our findings support the suggested association between LMMQs and the observed distribution of the 511 keV line flux observed by INTEGRAL.

Processes in alkaline peroxide bleaching of pinus radiata tmp

description: The response of Pinus radiata thermomechanical pulp to alkaline peroxide has been studied. Factors influencing the maximum brightness attained for various bleaching conditions have also been examined and the concepts of 'reagent limited' and 'pulp limited' have been related to the observation of limiting brightness on repeated bleaching. Further observations were carried out on the kinetic behaviour during constant reagent concentration. Several previously reported kinetic models have been tested and found to be inadequate to describe the observed kinetic behaviour in terms of a minimum of chemically meaningful parameters. From the experimental evidence, a new kinetic model which is defined in terms of first order processes has been proposed. This model assumes the existence of a single class of chromophores which reacts to give colourless products and potential chromophores. The process of the elimination of chromophores is opposed by a colour formation process from the conversion of potential chromophores to chromophores in an equilibrium type reaction. The 'equilibrium' model was found not only to be able to describe the observed light absorption coefficients - time (K-t) relationship under constant reagent concentration, but also to explain the response of the pulp when reagent concentrations are changed part way through the bleaching process. Previously reported results on the reactions between alkaline peroxide and the model lignin chromophore cinnamaldehyde have been studied by means of computational methods. From these calculations, it was found that the epoxidation of cinnamaldehyde is exothermic with an overall activation energy close to zero. The experimental presence of two epoxide isomers with the trans isomer as the preferred product agrees with the results of our calculations. Good agreement between the results of the less sophisticated PM3 calculations and the more sophisticated ab initio calculations at RHF/6- 31G(d) suggest that PM3 can be used for further studies without sacrificing significant accuracy of the results. PM3 is also computationally preferred since it generally requires less computation time to perform. The research presented in this thesis is an extension of the work performed by the author during his study at an undergraduate level. As such, some of the results which were obtained from the previous study are included in parts of this thesis.

description: We report $^{75}$As nuclear quadrupole resonance (NQR) studies on superconducting oxypnictide LaFeAsO$_{0.92}$F$_{0.08}$ ($T_{\rm c}$ = 23 K). The temperature dependence of the spin lattice relaxation rate (1/$T_1$) decreases below $T_{\rm c}$ without a coherence (Hebel-Slichter) peak and shows a temperature dependence that is not simple power-law nor exponential. We show that the result can be understood in terms of two superconducting gaps of either $d$- or ${\pm}s$-wave symmetry, with the larger gap $Δ_1\sim 4 k_{\rm B}T_{\rm c}$ and the smaller one $Δ_2 \sim 1.5 k_{\rm B}T_{\rm c}$. Our result suggests that the multiple-gaps feature is universal in the oxypnictides superconductors, which is probably associated with the multiple electronic bands structure in this new class of materials. We also find that 1/$T_1T$ above $T_{\rm c}$ increases with decreasing temperature, which suggests weak magnetic fluctuations in the normal state.

description: Аннотация. В статье изучена история геноцида евреев и крымчаков в оккупированном нацистами Крыму. Анализ данных Республиканской комиссии и архивных материалов позволил установить масштабы и методы уничтожения этих групп населения, которые показывают жестокость реализации политики Холокоста на полуострове. Сделан вывод, что геноцид в отношении евреев и крымчаков на территории Крыма в период немецко-фашистской оккупации осуществлялся систематически, благодаря запугиванию местного населения и активной пропаганде, как среди обычных людей, так и среди военнопленных. Отдельные представители местного населения переходила на сторону нацистов и помогала в уничтожении еврейского и крымчакского населения. 

Abstract. The article examines the history of the genocide of Jews and Krymchaks in Nazi-occupied Crimea. An analysis of the data of the Republican Commission and archival materials allowed us to establish the scale and methods of extermination of these population groups, which show the cruelty of the Holocaust policy on the peninsula. It is concluded that the genocide against Jews and Krymchaks in Crimea during the Nazi occupation was carried out systematically, thanks to intimidation of the local population and active propaganda, both among ordinary people and among prisoners of war. Some representatives of the local population went over to the side of the Nazis and helped in the extermination of the Jewish and Krymchak population.
title: Effects of Computer Simulation and Animation (CSA) on Students’ Problem Solving in Engineering Dynamics: What and How
Creators: name: Tajvidi, Seyed Mohammad

description: The application of Computer Simulation and Animation (CSA) in the instruction of engineering dynamics has shown a significant growth in the recent years. The two foremost methods to evaluate the effectiveness of CSA tools, including student feedback and surveys and measuring student change in performance, suggest that CSA modules improve student learning in engineering dynamics. However, neither method fully demonstrates the quality of students’ cognitive changes.
This study examined the quality of effects of application of CSA modules on
student learning and problem solving in particle dynamics. It also compared CSA
modules with textbook-style problem-solving regarding the changes they cause in
students’ cognitive process. A qualitative methodology was adopted to design and
implement a study to explore the changes in participants’ learning and problem-solving behavior caused by using a CSA module. Collected data were coded and analyzed using the categories of cognitive process based on the Revised Bloom’s Taxonomy.
An analysis of the results revealed that the most significant effects were observed
in understanding, analyzing, and evaluating. The high frequency of “inference” behavior after working with modules indicated a significant increase in participants’ understanding activity after working with computer modules. Comparing behavior changes of computer-simulation group students with those who worked with a textbook-style example demonstrated that the CSA modules ignited more analytical behavior among students than did textbook-style examples. This study illustrated that improvement in learning due to the application of CSA is not limited to conceptual understanding; CSA modules enhance students’ skills in applying, organizing, and evaluating as well. The interactive characteristics of CSA play a major role in stimulating students’ analytical reasoning and critical thinking in engineering dynamics.

description: A simple optical to mid-IR color selection, R-[24] > 14, i.e. f_nu(24) / f_nu(R) > 1000, identifies highly dust obscured galaxies (DOGs) with typical redshifts of z~2 +/- 0.5. Extreme mid-IR luminosities (L_{IR} > 10^{12-14}) suggest that DOGs are powered by a combination of AGN and star formation, possibly driven by mergers. In an effort to compare their photometric properties with their rest frame optical morphologies, we obtained high spatial resolution (0.05 -0.1") Keck Adaptive Optics (AO) K'-band images of 15 DOGs. The images reveal a wide range of morphologies, including: small exponential disks (8 of 15), small ellipticals (4 of 15), and unresolved sources (2 of 15). One particularly diffuse source could not be classified because of low signal to noise ratio. We find a statistically significant correlation between galaxy concentration and mid-IR luminosity, with the most luminous DOGs exhibiting higher concentration and smaller physical size. DOGs with high concentration also tend to have spectral energy distributions (SEDs) suggestive of AGN activity. Thus central AGN light may be biasing the morphologies of the more luminous DOGs to higher concentration. Conversely, more diffuse DOGs tend to show an SED shape suggestive of star formation. Two of fifteen in the sample show multiple resolved components with separations of ~1 kpc, circumstantial evidence for ongoing mergers.

title: Evaluating the Effectiveness of Utah Farm Field Days
Creators: name: Wray, Paige
Publisher: name: Utah State University

description: The goal of farm field days in Utah is to show an increase in agricultural literacy among elementary aged children. Evaluations of student learning have not been adequately assessed. Students from two of the statewide farm field day events were assessed on what they already knew about agriculture, what they wanted to learn about agriculture, and then what they learned about agriculture as a result of the event they attended. Data was collected and analyzed using the National Agriculture Literacy Outcomes and Themes, to determine if the farm field day events had any impact on their awareness or understanding of agriculture. Results indicated that students were below an average awareness of younger grade-level appropriate agricultural concepts before they attend the farm field day event. However, after the event, results indicated that student awareness of grade appropriate agricultural concepts increased.
