description: Classroom dashboards are designed to help instructors effectively orchestrate classrooms by providing summary statistics, activity tracking, and other information. Existing dashboards are generally specific to an LMS or platform and they generally summarize individual work, not group behaviors. However, CS courses typically involve constellations of tools and mix on- and offline collaboration. Thus, cross-platform monitoring of individuals and teams is important to develop a full picture of the class. In this work, we describe our work on Concert, a data integration platform that collects data about student activities from several sources such as Piazza, My Digital Hand, and GitHub and uses it to support classroom monitoring through analysis and visualizations. We discuss team visualizations that we have developed to support effective group management and to help instructors identify teams in need of intervention.

description: The Monte Carlo HYDJET++ model, that contains both hydrodynamic state and jets, is applied to study the influence of the interplay between soft and hard processes on the formation of the elliptic flow in heavy-ion collisions at RHIC and LHC energies. Jets are found to cease the hydro-like increase of the elliptic flow with rising p_T. Since jets are more influential at LHC than at RHIC, the v_2 at LHC should be weaker than that at RHIC. Violation of the number-of-constituent-quark (NCQ) scaling is predicted. The decays of resonances are found to enhance the low-p_T part of the elliptic flow of pions and light baryons, and work toward the fulfillment of the NCQ scaling.

description: We study the Hamiltonian approach to Yang-Mills theory in Coulomb gauge in Rayleigh-Schroedinger perturbation theory. The static gluon and ghost propagator as well as the potential between static colour sources are calculated to one-loop order. Furthermore, the one-loop $β$-function is calculated from both the ghost-gluon vertex and the static potential and found to agree with the result of covariant perturbation theory.

The effect of the interaction between test expectancy and question placement on incidental learning
Creators: name: Koe, George Gerald
Publisher: name: University of British Columbia
Year: 2010

description: Problem The purpose of this study was to investigate the effect of and the interaction between test expectancy and question placement on incidental learning from prose materials. It was expected that post-adjunct questions would lead to higher scores on a test of incidental learning than pre-adjunct questions. It was also expected that a test expectancy condition would lead to higher scores on a test of incidental learning than questions without test expectancy. Methods of Investigation The study sample was limited to Grade Ten and Eleven students enrolled in the Mission Senior Secondary School (Mission, B.C.) during the 1972-73 session. The study used a two by two by two factorial design. The factors were: a) question placement (pre-adjunct or post-adjunct), b) test expectancy (test expectancy present or test expectancy absent), and c) race (Indian or non-Indian) . The major hypotheses of this study were based on a two by two by two analysis of variance of scores on a test of incidental questions. This analysis tested the factors described in the design. General Conclusions The major conclusion of this study was that neither question placement nor test expectancy supported expectations which were based on the theoretical contentions of Rothkopf (1966, 1970). Moreover, findings with regard to question placement did not support expectations which were based on the findings of previous investigators (Frase, 1967; Rothkopf, 1966; Rothkopf & Bisbicos, 1967) . The only statistically significant findings of this study were that Indian subjects achieved higher scores than non-Indian subjects on the test of the incidental questions when test expectancy was absent and that Indian subjects achieved lower scores on the test of incidental questions than non-Indian subjects when test expectancy was present. However, the low reliabilities for the Indian subjects' scores, the wide variance in the non-Indian group, and the small sample size of the Indian group placed considerable constraint on the interpretation of this finding.

description: The detection of upward propagating internal gravity waves at the base of the Sun's chromosphere has recently been reported by Straus et al., who postulated that these may efficiently couple to Alfven waves in magnetic regions. This may be important in transporting energy to higher levels. Here we explore the propagation, reflection and mode conversion of linear gravity waves in a VAL C atmosphere, and find that even weak magnetic fields usually reflect gravity waves back downward as slow magnetoacoustic waves well before they reach the Alfven/acoustic equipartition height at which mode conversion might occur. However, for certain highly inclined magnetic field orientations in which the gravity waves manage to penetrate near or through the equipartition level, there can be substantial conversion to either or both upgoing Alfven and acoustic waves. Wave energy fluxes comparable to the chromospheric radiative losses are expected.

Reflection of light from a uniformly moving mirror

description: We developed a formula for the law of reflection of a plane-polarized light beam from an inclined flat mirror in uniform rectilinear motion by a direct application of the Huygens-Fresnel principle. Applying the obtained formula and the postulates of special relativity to describe a specific thought experiment, we showed that the moving mirror must be contracted along the direction of its motion by the usual Lorentz factor. The result emphasizes the reality of Lorentz contraction by showing that the contraction is a direct consequence of the first and second postulates of special relativity, and not a product of the process of relativistic measurement of the length.

description: The information capacity of the universe has been a topic of great debate since 1970s, and continues to stimulate multiple branches of physics research. Here we used Shannon's information theory to estimate the amount of encoded information in all the visible matter in the universe. We achieved this by deriving a detailed formula estimating the total number of particles in the observable universe, known as the Eddington number, and by estimating the amount of information stored by each particle about itself. We determined that each particle in the observable universe contains 1.509 bits of information and there are 6 * 10 to power 80 bits of information stored in all the matter particles of the observable universe.

In our analyses, we define high values as those that fall within the top 25% of values for a given indicator across all BLM and USFS lands within the state, regardless of management or protection status. We identified and mapped millions of acres of BLM and USFS lands that could be considered of high ecological value that would stand to be lost if they are leased for O&G development. These analyses are intended to be used to inform efforts by BLM and DOI decision-makers evaluating whether particular lands should be removed from consideration for O&G development.Recommended citation: Conservation Science Partners (CSP). 2023.

description: By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn$_3$)Mn$_4$O$_{12}$, where a peculiar quadruple perovskite structure with no oxygen disorder stabilizes a nearly full Mn$^{3+}$/Mn$^{4+}$ static charge order at $T_{\rm CO}$=175 K concomitant to a commensurate structural modulation with propagation vector ${\bf q}_{\rm CO}=(\frac{1}{2},\frac{1}{2},0)$. At $T_{\rm CO}$, the IXS spectra unveil a softening of a 35.3 meV phonon at ${\bf q}_{\rm CO}$. Lattice dynamical calculations enable us to attribute this soft phonon to a A$_g$ mode whose polarization matches the Jahn-Teller-like distortion pattern of the structural modulation. This result demonstrates that the Jahn-Teller instability is the driving force of the CO Verwey transition in (NaMn$_3$)Mn$_4$O$_{12}$, thus elucidating a long-standing controversy regarding the mechanism of this transition observed in other mixed-valence systems like magnetite.

In this paper, I argue that the UChicago my.classes registration portal is in desperate need of a redesign and propose a solutions via a mock up.
title: Petrology and Mineralogy of Tertiary Volcanic Rocks in the Vicinity of the Rozel Hills and Black Mountain, Box Elder County, Utah
Creators: name: Greenman, Elizabeth R.
Publisher: name: Utah State University
Year: 1982

description: Two basalt flows and an andesite fissure eruption occur in the Rozel Hills - Black Mountain area in Box Elder County, Utah. Both basalt flows are aphanitic, and contain olivine, plagioclase, augite, and opaque oxides. They may be distinguished both chemically and on the basis of their textures. Unit 2 basalt is finer grained, and appears to be associated with a fault in the Black Mountain area. Chemically, it is similar to high-iron lavas in the Craters of the Moon, Idaho area. It has higher alkali, total iron, and titanium contents that Unit 1 basalt. Unit 1 basalt is similar to other tholeiitic basalts in the Basin and Range province. It is coarser-grained and has higher silicon, magnesium, aluminum, and calcium contents than Unit 2 basalt. While the basalts have characteristics of alkali-olivine basalts, such as absence of calcium-poor pyroxene, and a high alkali to silica ratio, both units are hypersthene- and olivine-nonnative and classified as olivine tholeiites. Subsurface basalt in the area appears to represent both lava types, but extensive alteration makes comparison difficult. Andesite from the area is aphanitic, and contains plagioclase, orthopyroxene, and opaque oxides.
Temperatures of equilibration calculated from co-existing magnetite and ilmenite range f rom 1148°C to 745°C for basalt. Temperatures calculated from co-existing olivine and clinopyroxene range from 1009°C to 994°C.
While the two basalt units cannot be related by fractional crystallization at surface conditions, some parent - daughter relations are likely within each unit, and the andesite is most likely a differentiation product of Unit 1 basalt.
Partial melting of pyrolite and spinel lherzolite mantle compositions to produce Unit 1 and Unit 2 basalts was investigated. Since no unique temperature and pressure of equilbration for these melts and residu~l material from each mantle type was found, it is concluded that partial melting of a mantle of pyrolite or spinel lherzolite composition did not produce these lavas.
Unit 2 basalt may be derived from Unit 1 basalt by fractionation of high pressure (8 kb) phases. This mechanism, similar to that proposed for the Craters of the Moon - Snake River Plain system, may account for an evolved basalt (Unit 2) with a lower silica content than a less differentiated basalt (Unit 1).
title: Evaluation of Low-Temperature Geothermal Potential in North-Central Box Elder County, Utah
Creators: name: Davis, Matthew C.
Publisher: name: Utah State University
Year: 1984

description: The purpose of this study was to continue the assessment of low-temperature geothermal resources in Utah started . by the Utah Geological and Mineral Survey. The area of interest with in this report is north-central Box Elder County, Utah. Exploration techniques used included chemical analyses of water from wells and springs, temperature surveys, and temperature-depth measurements in unused wells within the study area. The highest water temperatures (31, 30, and 290c) recorded in this research were located in three separate geographic regions, suggesting that no single warm water occurrence dominates the study area.
Total dissolved solid (T:DS) concentrations ranged from 294 to 11,590 mg/1. Areas of warm water occurrences generally had TDS values of greater than 1,100 mg/1. Three water types were distinguished using trilinear plots of common ion analyses of collected water samples. The warmest wells were of Type III water character, which has high (>75%) sodium and chloride concentrations.
Reservoir temperatures were estimated using the water chemistry. Both the silica and the Na-K-Ca geothermometers were used to calculate reservoir temperatures, averaging between 500c and 1 ooo c. If mixing effects are taken into account, reservoir temperatures might be as high as 198°C.
Temperature-depth measurements were logged in 16 unused wells. Thermal gradients calculated from the profiles ranged from isothermal to 267oC/km. The background gradient for the study area appears to be slightly above the average Basin and Range gradient of 35oC/km. The highest gradients were calculated for the area approximately 8 kilometers west of Snowville, Utah, which is also an area of warm water.
Several areas of possible low-temperature geothermal interest have been identified in the study area by considering water temperatures, calculated reservoir temperatures, and temperature-depth data. However, additional work is needed to more accurately define the possible geothermal resource in these areas.

description: Market makers play a key role in financial markets by providing liquidity. They usually fill order books with buy and sell limit orders in order to provide traders alternative price levels to operate. This paper focuses precisely on the study of these markets makers strategies from an agent-based perspective. In particular, we propose the application of Reinforcement Learning (RL) for the creation of intelligent market markers in simulated stock markets. This research analyzes how RL market maker agents behaves in non-competitive (only one RL market maker learning at the same time) and competitive scenarios (multiple RL market markers learning at the same time), and how they adapt their strategies in a Sim2Real scope with interesting results. Furthermore, it covers the application of policy transfer between different experiments, describing the impact of competing environments on RL agents performance. RL and deep RL techniques are proven as profitable market maker approaches, leading to a better understanding of their behavior in stock markets.

The development of textbooks in English grammar for secondary schools in relation to the Latin tradition : a history of method as revealed by textbooks of the 16th, 17th, and 18th centuries

description: This study has been undertaken in an attempt to determine how far the traditional Latin method dominated the textbooks in English grammar for secondary schools, first in England, and later in America up to the time when Lindley Murray's grammar became the accepted authority and almost the sole model for school texts. That the Latin influence still survives is patent to the most casual observer familiar with both languages. Professor Jespersen sums up the present status of English grammar in these words: "Grammatical terminology is still in the main based on Latin grammar. The student of English will find in his grammatical vocabulary expressions for whatever English has in common with Latin, but those grammatical categories and phenomena which are not found in Latin have either no names at all, or else each author has his own names." One may well ponder over the reason for this fact when it is recalled that English grammars written for English-speaking students in the mother tongue have been in existence for more than three hundred years. That efforts have been made from time to time to throw off the Latin domination a cursory examination of a collection of 17th, 18th, and 19th century texts will show. The innovations of most importance have been noted and discussed by the historians of the language, and it is not probable that any one of them has escaped attention altogether. But so far, it seems, no detailed study has been made of the relation between Latin and English grammar in successive periods, giving a specific account of the similarities and differences, the changes of form and shifts of emphasis, as revealed in the texts themselves. It is to this end that the present study will be directed. Its specific purpose will be to record the results of an analysis of a selected line of grammar texts representative of the various stages in the development of English grammar in England and America from its beginning to the end of the 18th century

description: In our galaxy, white dwarfs inevitably undergo scattering and capture processes with the interstellar diffuse dark matter. The captured dark matter forms a dark halo that eventually evaporates or annihilates. Theoretical pulsation modes and observations of pulsating white dwarfs provide predictions about their evolution. This motivates us to study the impact of sub-MeV interstellar dark matter on the cooling processes of white dwarfs. In this work, we consider the collisions between dark matter and relativistic degenerate electrons inside white dwarfs, numerically calculating the energy input and output results from scattering, capture, evaporation, and annihilation processes. Based on observational data from G117-B15, we conclude that the maximum cooling luminosity of the interstellar sub-MeV dark matter is approximately $10^{22} \, \text{erg}/\text{s}$, which is insufficient to provide an effective cooling mechanism for white dwarfs. Finally, if future observations detect a pulsating white dwarf in the Galactic center, the potential sensitivity of this scenario could extend to the region$10^{-3}\,\text{MeV} < m_χ< 10 \, \text{MeV}$ and $6.02 \times 10^{-38}\,\text{cm}^2 > σ_0 \geq 1.5 \times 10^{40} \, \text{cm}^2$.

description: In this paper we derive analytical relations between probabilities of the excited state transfers and entanglements calculated by both the Wootters and positive partial transpose (PPT) criteria for the arbitrary spin system with single excited spin in the external magnetic field and Hamiltonian commuting with $I_z$. We apply these relations to study the arbitrary state transfers and entanglements in the simple systems of nuclear spins having two- and three-dimensional geometrical configurations with $XXZ$ Hamiltonian. It is shown that High-Probability State Transfers (HPSTs) are possible among all four nodes placed in the corners of the rectangle with the proper ratio of sides as well as among all eight nodes placed in the corners of the parallelepiped with the proper ratio of sides. Entanglements responsible for these HPSTs have been identified.

title: Structure and Petrology of Tertiary Volcanic Rocks in Parts of Toms Cabin Spring and Lucin NW Quadrangles (Box Elder Co.), Utah
Creators: name: Scarbrough, Bruce Edward
Publisher: name: Utah State University
Year: 1984

description: A series of late Tertiary rhyolitic and dacitic flows, domes, and minor pyroclastic rocks form an elongate volanic mass along the northwestern Utah-northeastern Nevada border . The structure of the flow banding and the linear arrangement of vents indicate that the mass represents a multi-sourced extrusive complex which erupted through many fissure-type conduits. A 39 km2 area at the southern end of the mass was studied in detail in order to gain a better understanding of the eruptive nature and history of these Tertiary volcanic rocks. Age dating reveals that volcanism in the study area was episodic, and covered a period of at least 4 to 5 million years.
The silicic volcanic rocks in the study area are similar chemically and mineralogically to other eruptive units within the Rhyolite Mts., which range from dacite (Si0 2 69%) to high-silica rhyolite (SiOz 75-77%). They also exhibit chemical characteristics similar to other silicic volcanic rocks of bimodal association in the western United States. Two-feldspar high-K rhyolite is the dominant volcanic rock in the study area, commonly found overlying rhyolitic vitric tuffs and agglomerates. Rhyolite from the southern portion of the study area is dated at 7.6 to 8.6 m.y.b.p. Dacitic samples contain phenocrysts of plagioclase, quartz, biotite, hornblende, and orthopyroxene. Dacitic volcanism is dated at 12.4 m.y.b.p. By analogy with other "bimodal" volcanic fields in the western U.S., it is assumed that these si 1 icic magmas are products of partial melting of crustal rocks. Evidence from a least squares differentiation model, along with the overall geochemical characteristics, indicates crystal fractionation as the dominant mechanism for the transition from dacite to rhyolite, with plagioclase as the dominant fractionating phase.

description: The galaxy population is strongly bimodal in both colour and morphology, and the two measures correlate strongly, with most blue galaxies being late-types (spirals) and most early-types, typically ellipticals, being red. This observation has led to the use of colour as a convenient selection criteria to make samples which are then labelled by morphology. Such use of colour as a proxy for morphology results in necessarily impure and incomplete samples. In this paper, we make use of the morphological labels produced by Galaxy Zoo to measure how incomplete and impure such samples are, considering optical (ugriz), NUV and NIR (JHK) bands. The best single colour optical selection is found using a threshold of g-r = 0.742, but this still results in a sample where only 56% of red galaxies are smooth and 56% of smooth galaxies are red. Use of the NUV gives some improvement over purely optical bands, particularly for late-types, but still results in low purity/completeness for early-types. No significant improvement is found by adding NIR bands. With any two bands, including NUV, a sample of early-types with greater than two-thirds purity cannot be constructed. Advances in quantitative galaxy morphologies have made colour-morphology proxy selections largely unnecessary going forward; where such assumptions are still required, we recommend studies carefully consider the implications of sample incompleteness/impurity.

description: The purpose of the present study was to explore the nature of the relationships between cognitive style, conceptual tempo, and processes employed by fifth grade children during verbal problem solving. In addition, the effectiveness of programmed instruction to train children in the use of analytic and reflective modes of problem solving was investigated. Cognitive style (analytic responses on Denney's Cognitive Style Test), conceptual tempo (errors and latency of response on Kagan's Marching Familiar Figures Test), verbal creative thinking ability, and school achievement were determined for eighty-one children in three fifth grade classes. Verbal creative thinking ability and school achievement were treated .as covariates. Classes were randomly assigned to three treatment conditions: 1) problem solving training via programmed instruction; 2) programmed instruction of unrelated content; 3) no programmed instruction. The treatment, style, and tempo variables were evaluated in terms of their effects upon ten measures of problem solving which included time spent on four criterion problems, quantity and quality of questions asked, and number of solutions offered. The data indicated that training was successful in increasing time spent on the problems, and quantity and quality of questions asked, but had no effect on number of solutions offered. However, aptitude by treatment interactions between training and both style and tempo indicated that the performance of non-analytic and highly impulsive children was no better than untrained children of similar style and tempo. While conceptual tempo was found to account for a significant amount of the variance in the three measures of time spent on the problems and one measure of question asking, cognitive style was not an important contributor to measures of problem solving. Interactions were repeatedly found between style and tempo which indicated that these two variables tended to have a moderating effect on each other. Thus, a child who was highly impulsive performed reflectively if he was also highly analytic. Likewise, a non-analytic child performed analytically if he was also highly reflective. While school achievement was not related to performance, verbal creative thinking ability was found to be positively related to problem solving performance, with verbal originality being a better predictor than either verbal fluency or flexibility. A limitation of this study arose from differences in teaching style to which the students had been exposed during the eight months preceding this study. As a result of the analyses, it was concluded that a reappraisal of the effects of style and tempo is warranted, with attention given to the interaction between these two variables. Assessment of the effectiveness of modified versions of the present self-paced training program with non-analytic and highly impulsive children was recommended.

description: We report the first study to characterise intranight variability of the blazar class from the perspective of (rest-frame) UV emission. For this, we carried out intranight optical monitoring of 14 flat-spectrum radio quasars (FSRQs) located at high redshifts (1.5 < $z$ < 3.7), in 42 sessions of median duration $\sim$ 5.4 hr. These sources were grouped into two samples distinguished by published fractional optical polarisation: (i) nine low-polarisation sources with $p_{opt} < 3\%$ and (ii) five high-polarisation sources. Unexpectedly, a high duty cycle (DC $\sim$ 30$\%$) is found for intranight variability (with amplitude $ψ> 3\%$) of the low-polarisation sources. This DC is a few times higher than that reported for low-polarisation FSRQs located at moderate redshifts ($z$ $\sim$ 0.7) and hence typically monitored in the rest-frame blue-optical. Further, we found no evidence for an increased intranight variability of UV emission with polarisation, in contrast to the strong correlation found for intranight variability of optical emission. We briefly discuss this in the context of an existing scenario which posits that the nonthermal UV emission of blazars arises from a relativistic particle population different from that radiating up to near-infrared/optical frequencies.

description: Due to the strong nonlinearity and nonholonomic dynamics, despite the various general trajectory optimization methods presented, few of them can guarantee efficient computation and physical feasibility for relatively complicated fixed-wing UAV dynamics. Aiming at this issue, this paper investigates a differential flatness-based trajectory optimization method for fixed-wing UAVs (DFTO-FW). The customized trajectory representation is presented through differential flat characteristics analysis and polynomial parameterization, eliminating equality constraints to avoid the heavy computational burdens of solving complex dynamics. Through the design of integral performance costs and derivation of analytical gradients, the original trajectory optimization is transcribed into a lightweight, unconstrained, gradient-analytical optimization with linear time complexity to improve efficiency further. The simulation experiments illustrate the superior efficiency of the DFTO-FW, which takes sub-second CPU time (on a personal desktop) against other competitors by orders of magnitude to generate fixed-wing UAV trajectories in randomly generated obstacle environments.

title: Petrology of the Middle Jurassic Twin Creek Limestone, Lincoln and Sublette Counties, Southwestern Wyoming
Creators: name: Raubvogel, David R.
Publisher: name: Utah State University
Year: 1984

description: The Twin Creek Limestone of Middle Jurassic age was studied in the Tunp, Salt River, and Wyoming Ranges in southwestern Wyoming. Modern carbonate environments and their ancient analogs were compared with information obtained from field study and petrographic analysis of samples of the Twin Creek Limestone in order to delineate environments of deposition, paleogeography, and diagenetic history.
Six major lithofacies were recognized: (1) carbonate mudstone; (2) carbonate mudstone breccia; (3) fossiliferous wackestone; (4) packstone-grainstone; (5) terrigenous mudstone; and (6) sandstone. These lithofacies were deposited in a variety of environments, including outer shelf platforms (carbonate mudstone and fossiliferous wackestone), oolitic sand belts (packstone-grainstone), open to restricted lagoons (carbonate mudstone, fossiliferous wackestone, and terrigenous mudstone), tidal flats, and supratidal environments (terrigenous mudstone, sandstone and carbonate mudstone breccia). The Twin Creek epeiric seaway experienced two major transgressions (early Bajocian and late Bathonian-early Cal lovian) and two regressions (early Bathonian and middle Callovian). Lateral migration of the adjacent facies occurred in response to these changes in sea level.
Eogenetic features include minor compaction, micritization, coarse fibrous rim cementation, granular cementation, syntaxial rim cementation and silicification of carbonates. These features were produced in environments ranging from freshwater phreatic to marine phreatic. Mesogenetic diagnesis was characterized by pressure-solution features and neomorphism. Telogenetic features are limited to calcite vein-fillings and oxidation coatings on carbonate and detrital gains and cements.
title: Extension of Behavioral Momentum Theory to Conditions with Changing Reinforcer Rates
Creators: name: Craig, Andrew R
Publisher: name: Utah State University

description: Behavioral momentum theory states that resistance to change of operant behavior is governed by the Pavlovian stimulus-reinforcer relation in a given discriminative stimulus situation. That is, higher reinforcer rates in the presence of a discriminative stimulus result in a stronger stimulus-reinforcer relation and, thereby, greater resistance to change. Within the momentum-based quantitative framework of resistance to change, the construct relating persistence to pre-disruption reinforcer rates is termed “behavioral mass.” All research on which momentum theory is based has examined resistance to change following prolonged exposure to stable reinforcer rates in multiple schedules of reinforcement. Thus, at present little is known about the time frame over which behavioral mass accumulates or the manner by which newly experienced stimulus reinforcer relations are incorporated into mass when these rates change. The experiments described in this dissertation aimed to clarify these facets of the construct. Chapters 1 and 2 provide a detailed overview behavioral momentum theory and resistance to change. Topics discussed include quantitative models of resistance to change, clinical implications of resistance-to-change research, some notable limitations of behavioral momentum theory, and extensions of the theory to account for diverse behavioral outcomes. A recently published study is presented in Chapter 3 that aimed to determine how resistance to change and behavioral mass of pigeons’ key pecking adapts in the face of stimulus-reinforcer relations that change across time during baseline. Results suggest that resistance to change is a function of recently experienced stimulus-reinforcer relations and that behavioral mass depends most heavily on these recent experiences. The experiment described in Chapter 4 extended the findings reported in Chapter 3 by examining whether behavioral mass changes during operant extinction. Pre-exposure to extinction in an alternative multiple-schedule component decreased resistance to extinction of target-component key pecking relative to conditions without pre-exposure to extinction. Between-condition differences in extinction were well accounted for quantitatively by either variation in behavioral mass or changes in the magnitude of factors that are assumed to disrupt responding during extinction. Chapter 5 offers an integrative discussion of this research and emphasizes theoretical implications, practical applications, and areas for future research.
