title: The Effect of an Extended Music Curriculum on the Behavior of Nursery School Children
Creators: name: Miller, Dorothy Ann
Publisher: name: Utah State University
Year: 1968

description: The free play behavior of two of the Utah State University nursery school groups was observed and recorded according to the time sampling instrument devised to assess the musical activity of children. Twelve group music experiences, in addition to those of the regular curriculum, were presented to the experimental group while the control group received two such experiences.
Sex was found not to be a significant factor in the amount of musical activity; however, girls were slightly more active rhythmically than the boys. The children between 3 years 10 months and 4 years 4 months were the most active musically and there was a slight tendency toward increased music activity at nursery school as music involvement in the home increased . The amount of music activity increased as the number of quarters of nursery school attendance increased.
The data depict the experimental children as involved in more music experiences per day; involved for a greater number of days, especially in rhythmic movement; creating more individual music experiences with an increasing amount of rhythmic content and covering a longer period of time, as compared to the control group. Because the findings were not statistically significant, the null hypothesis stated as, "The inclusion of an extended music curriculum in the nursery school program produces no significant change in the behavior of preschool children," was held tenable .

title: Reproductive Strategies of Northern Goshawks and Cooper's Hawks in North-Central New Mexico
Creators: name: Kennedy, Patricia L.
Publisher: name: Utah State University
Year: 1991

description: I assumed that the reproductive strategies of the two Accipiter species investigated in this study, the northern Goshawk (A. gentilis) and the Cooper's hawk (A. cooperii), would be similar to the strategies of other monogamous raptors with sex role partitioning. Any differences in the species' reproductive strategies, particularly hunting strategies, were expected to be a function of their size differences. Contrary to predictions, results indicated that, in north-central New Mexico during brood rearing, both species had similar hunting strategies and utilized similar prey species. These results also indicated that the reproductive strategies of the Cooper's hawk were not adequately described by simple models of sex role partitioning.
In this population, over 50% of the female Cooper's hawks deserted during the fledgling-dependency period and made no attempt to renest. In all cases of desertion, the male provided uniparental care until the young were independent. Based on time-energy budget estimates, the deserting females were in poorer physical condition at the time of desertion than were the nondeserting females. This was attributed to the deserter preferentially feeding the nestlings when the quantity of food delivered to the nest by either parent was inadequate to meet the family's requirements.
Based on these observations, I developed a dynamic stochastic optimization model to explore the hypotheses that (1) the optimal reproductive strategy of the female Cooper's hawks is the strategy that maximizes her reproductive fitness; and (2) the major factors affecting the female's reproductive fitness and, thus, her optimal strategies are her physical condition, the physical condition of the nestlings, the risks to the nestlings associated with each strategy, and the foraging capabilities of her mate. The model defined reproductive fitness as the weighted average of the nestlings' expected survival and the female's expected reproductive potential in the next breeding season. Using independent sources for the parameters, the model validation compared the model predictions with actual observations of the behavior of radio-tagged, nesting females in this population of Cooper's hawks. The model correctly predicted 90% of the strategies exhibited by the nesting females, which supported the initial hypotheses.

description: This study investigates the dynamic interconnectedness between automated teller machines and bank profitability in Nigeria from 2009 to 2023.  The findings reveal valued perceptions into the impact of Fintech on bank profitability as a whole. We found a positive and non-significant long-run relationship between Automated teller machines and bank profitability which suggests that banks can consider optimizing the placement and accessibility of their ATM terminals. These results emphasize the importance of banks boosting the placement and accessibility of their ATM terminals to enhance the effectiveness of ATM services and improve profitability. Concerted efforts to position these machines in an area with significant pedestrian activity can effectively attract a larger customer base while maintaining cost efficiency. The implementation of machines that provide rapid service and save time by eliminating the need to visit physical banks significantly improves customer satisfaction. We also recommend experimental initiatives designed to evaluate alternative financial models, including biometric ATMs to tackle Nigeria's specific difficulties.

description: We study systematically transport, susceptibility and heat capacity for BaFe$_{2-x}$Co$_x$As$_2$ single crystals. In the underdoped region, spin density wave (SDW) transition is observed in both resistivity and susceptibility. The magnetic susceptibility shows unusual T-linear dependence above SDW transition up to 700 K. With Co doping, SDW ordering is gradually suppressed and superconductivity emerges with a dome-like shape. Electrical transport, specific heat and magnetic susceptibility indicate that SDW and superconductivity coexist in the sample BaFe$_{2-x}$Co$_x$As$_2$ around x = 0.17, being similar with (Ba,K)Fe$_2$As$_2$. When x$>$0.34, the superconductivity completely disappears. A crossover from non-Fermi-liquid state to Fermi-liquid state is observed with increasing Co doping. A detailed electronic phase diagram about evolution from SDW to superconducting state is given.

description: Starting from the quantum Monte Carlo (QMC) prediction for the ground-state energy of a clean two-dimensional one-valley (2D1V) electron gas, we estimate the energy correction due to scattering sources present in actual devices such as AlAs quantum wells and GaAs heterostructures. We find that the effect of uncorrelated disorder, in the lowest (second) order in perturbation theory, is to enhance the spin susceptibility leading to its eventual divergence. In the density region where the Born approximation is able to reproduce the experimental mobility, the prediction for the spin susceptibility yielded by perturbation theory is in very good agreement with the available experimental evidence.

description: We generalize recent analysis of the dynamics of point particle in Horava-Lifshitz background to the case of string probe when we replace the Hamiltonian constraint of the Polyakov string with the constraint that breaks Lorentz invariance of target space-time. Then we find corresponding Lagrangian and argue that the world-sheet theory is invariant under foliation preserving diffeomorphism. Finally we discuss the Hamiltonian dynamics and show that this is well defined on condition that the world-sheet lapse function obeys the projectability condition.

description: In this paper are presented the production methods for very "high specific activity" radionuclides (HSARNs) of vanadium (V), manganese (Mn) and thallium (Tl), which have been developed in our laboratories for labeling different chemical forms of these elements present in the echo-systems in ultra-trace amounts, for metallo-toxicological and bio-kinetic studies. Use was made of both cyclotron and thermal nuclear reactor. If the nuclear reaction and/or decay product has atomic number different from irradiated target, it is possible separating the radioactive nuclide from irradiated target, without intentional addition of isotopic carrier. These kinds of radionuclides are named No Carrier Added, NCA, and their specific activity is very high and can reach values close to the theoretical Carrier Free one, CF. The experimental determination of specific activity, chemical and radiochemical purities is mandatory for all these kinds of applications.

description: In this paper, the method of Singular Spectrum Analysis (SSA) is applied for investigation of the zenith troposphere delay time-series derived from VLBI observations. With the help of this method we can analyze the structure of time-series and separate the harmonic and irregular (trend) components. Combined IVS time-series of zenith wet and total troposphere delays obtained in IGG were used for analysis. For this study, several VLBI stations with the most long time series of troposphere zenith delays were selected, also taking into consideration the geographic region where the station is located. The investigations were carried out using SSA mode. As a result, trends and seasonal components (with annual and semiannual periods) were obtained for all the stations. Using of SSA enabled us to determine nonlinear trends in zenith delay, and also to study variations in the amplitude and the phase of the seasonal components with time.

description: We apply the coupled cluster method (CCM) in order to study the ground-state properties of the (unfrustrated) square-lattice and (frustrated) triangular-lattice spin-half Heisenberg antiferromagnets in the presence of external magnetic fields. Here we determine and solve the basic CCM equations by using the localised approximation scheme commonly referred to as the `LSUB$m$' approximation scheme and we carry out high-order calculations by using intensive computational methods. We calculate the ground-state energy, the uniform susceptibility, the total (lattice) magnetisation and the local (sublattice) magnetisations as a function of the magnetic field strength. Our results for the lattice magnetisation of the square-lattice case compare well to those results of QMC for all values of the applied external magnetic field. We find a value for magnetic susceptibility of $χ=0.070$ for the square-lattice antiferromagnet, which is also in agreement with the results of other approximate methods (e.g., $χ=0.0669$ via QMC). Our estimate for the range of the extent of the ($M/M_s=$)$\frac 13$ magnetisation plateau for the triangular-lattice antiferromagnet is $1.37< λ< 2.15$, which is in good agreement with results of spin-wave theory ($1.248 < λ< 2.145$) and exact diagonalisations ($1.38 < λ< 2.16$). The CCM value for the in-plane magnetic susceptibility per site is $χ=0.065$, which is below the result of the spin-wave theory (evaluated to order 1/S) of $χ_{SWT}=0.0794$.

description: q-Gaussians are probability distributions having their origin in the framework of Tsallis statistics. A continuous real parameter q is characterizing them so that, in the range 1 < q < 3, the q-functions pass from the usual Gaussian form, for q close to 1, to the Cauchy-Lorentzian distribution for q=2. For q greater than 2, the distribution is a heavily tailed one. This behavior of q-Gaussian functions can be used for the analysis of Raman spectra, instead of Gaussian, Lorentzian or Voigt profiles. In a first part of our research, we have provided several simulations and examples of q-Gaussian fitted Raman spectra and related band deconvolution. Here we continue the research work, providing supplementary information about the use of q-Gaussians, mainly considering the study of isolated bands.

description: In this article, we consider linearly convex complex cones in complex Banach spaces and we define a new projective metric on these cones. Compared to the hyperbolic gauge of Rugh, it has the advantage of being explicit, and easier to estimate. We prove that this metric also satisfies a contraction principle like Birkhoff's theorem for the Hilbert metric. We are thus able to improve existing results on spectral gaps for complex matrices. Finally, we compare the contraction principles for the hyperbolic gauge and our metric on particular cones, including complexification of Birkhoff cones. It appears that the contraction principles for our metric and the hyperbolic gauge occur simultaneously on these cones. However, we get better contraction rates with our metric.

description: DataGrid is project funded by the European Commission to develop and deploy distributed computing components for reference applications in the domains of Particle Physics, Earth Observation and Bioinformatics. The software development is shared among nine contractual partners, in seven different countries, and is organized in work-packages covering different areas. In this paper, we discuss how combination of Concurrent Version System, GNU autotools and other tools and practices was organised to allow the development, build, test and distribution of the DataGrid Workload Management Sys-tem. This is the product of one speci_c work-package that is not only characterised by rather high internal geographic and administrative dispersion (four institutions with de-velopers at nine different locations in three countries), but by the fact we had to integrate and interface to dozen of third-party code packages coming from different sources, and to the software products coming from other three development work-packages internal to the project. high level of central co-ordination needed to be maintained for project-wide steering, and this had also to be re_ected in the software development infrastructure, while maintaining ease-of-use for distributed developers and automated procedures wherever possible.

description: In massive primordial galaxies, the gas may directly collapse and form a single central massive object if cooling is suppressed. Line cooling by molecular hydrogen can be suppressed in the presence of a strong soft-ultraviolet radiation field, but the role played by other cooling mechanisms is less clear. In optically thin gas, Lyman-Alpha cooling can be very effective, maintaining the gas temperature below 10^4 K over many orders of magnitude in density. However, the large neutral hydrogen column densities present in primordial galaxies render them highly optically thick to Lyman-Alpha photons. In this letter, we examine in detail the effects of the trapping of these Lyman-Alpha photons on the thermal and chemical evolution of the gas. We show that despite the high optical depth in the Lyman series lines, cooling is not strongly suppressed, and proceeds via other atomic hydrogen transitions, in particular the 2s-1s and the 3-2 transitions. At densities larger than 10^9 cm^{-3}, collisional dissociation of molecular hydrogen becomes the dominant cooling process and decreases the gas temperature to about 5000 K. The gas temperature evolves with density as $T \propto ρ^{γ_{\rm eff} - 1}$, with $γ_{\rm eff} = 0.97-0.98$. The evolution is thus very close to isothermal, and so fragmentation is possible, but unlikely to occur during the initial collapse. However, after the formation of a massive central object, we expect that later-infalling, higher angular momentum material will form an accretion disk that may be unstable to fragmentation, which may give rise to star formation with a top-heavy IMF.

Publisher: name: Utah State University
Year: 1984

description: This study investigated the acquisition of food by hand-reared coyotes, Canis latrans, of different social rank in a familiar area with and without novel objects (safe and potentially unsafe conditions). The first objective was to test the hypothesis that dominant animals are more hesitant than subordinates in approaching food in the presence of a novel stimulus. The results were that dominant pups usually were the first to feed in the absence of novel stimulus, and subordinate pups were the first to feed when novel objects were present.

description: There exist two popular energy-momentum tensors for an electromagnetic wave in a dielectric medium. The Abraham expression is robust to experimental verification but more mathematically demanding, while the Minkowski expression is the foundation of a number of simplifications commonly found within the literature, including the relative refractive index transformation often used in modelling optical tweezers. These simplifications are based on neglecting the Minkowski tensor's material counterpart, a process known to be incompatible with conservation of angular momentum, and in conflict with experimental results, yet they are very successful in a wide range of circumstances. This paper combines existing constraints on their usage with recent theoretical analysis to obtain a list of conditions which much be satisfied to safely use the simplified Minkowski approach. Applying these conditions to an experiment proposed by Padgett et al., we find their prediction in agreement with that obtained using the total energy-momentum tensor.

description: A popular measure of model fit in structural equation modeling (SEM) is the standardized root mean squared residual (SRMR) fit index. Equivalence testing has been used to evaluate model fit in structural equation modeling (SEM) but has yet to be applied to SRMR. Accordingly, the present study proposed equivalence-testing based fit tests for the SRMR (ESRMR). Several variations of ESRMR were introduced, incorporating different equivalence bounds and methods of computing confidence intervals. A Monte Carlo simulation study compared these novel tests with traditional methods for evaluating model fit. The results demonstrated that certain ESRMR tests based on an analytic computation of the confidence interval correctly reject poor-fitting models and are well-powered for detecting good-fitting models. We also present an illustrative example with real data to demonstrate how ESRMR may be incorporated into model fit evaluation and reporting. Our recommendation is that ESRMR tests be presented in addition to descriptive fit indices for model fit reporting in SEM.

description: Phosphorus has long been recognized by agriculturists as being one of the elements essential for plant growth. Although the total phosphorus content of a soil may be high, the amount of phosphate actually available for plant growth is often low. Many agencies such as inherent low solubilities of phosphate compounds, adsorption on Ca C03, adsorption in the diffuse double layer of clay micelles, and chemical precipitation of phosphate which refers to the removal of phosphate ions from solution and their chemical bonding to the solid phase have been studied to explain the lack of phosphate availability.

description: The effects of maternal employment, as contrasted with maternal nonemployment, on the scholastic performance of children we re studied using a sample of 80 Mount Ogden Junior High seventh grade students and their mothers. The 80 mot hers concerned met the criterion for employment by having worked a forty-hour week outside the home the firs t six years their child attended school or the criteria of nonemployment by having never engaged in paid employment outside the home for the first six years of their child's schooling. Of nine areas tested between the two groups no significant difference was found concerning grade point average, reading achievement scores, absenteeisms, 10 Q ~ , conduct scores, education of the mother, and the number of hours that the mother and child spent together on a school day. A s i gni ficant difference at the .01 l eve l was found when comparing the numbe r of children in the family of employed mo thers (3. 3 ch ild r en) to the families of nonemployed mothers (4.5 chi l dren).

description: A thorough tensor analysis of the Bragg-forbidden reflection (00:3)h in corundum systems having a global center of inversion, such as V2O3 and a-Fe2O3, shows that anomalous x-ray resonant diffraction can access chiral properties related to the dipole-quadrupole (E1-E2) channel via an interference with the pure quadrupole-quadrupole (E2-E2) process. This is also confirmed by independent ab initio numerical simulations. In such a way, it becomes possible to detect chiral quantities in systems where dichroic absorption techniques are ineffective.

description: Missingness in intensive longitudinal data triggered by latent factors constitute one type of nonignorable missingness that can generate simultaneous missingness across multiple items on each measurement occasion. To address this issue, we propose a multiple imputation (MI) strategy called MI-FS, which incorporates factor scores, lag/lead variables, and missing data indicators into the imputation model. In the context of process factor analysis (PFA), we conducted a Monte Carlo simulation study to compare the performance of MI-FS to listwise deletion (LD), MI with manifest variables (MI-MV, which implements MI on both dependent variables and covariates), and partial MI with MVs (PMI-MV, which implements MI on covariates and handles missing dependent variables via full-information maximum likelihood) under different conditions. Across conditions, we found MI-based methods overall outperformed the LD; the MI-FS approach yielded lower root mean square errors (RMSEs) and higher coverage rates for auto-regression (AR) parameters compared to MI-MV; and the PMI-MV and MI-MV approaches yielded higher coverage rates for most parameters except AR parameters compared to MI-FS. These approaches were also compared using an empirical example investigating the relationships between negative affect and perceived stress over time. Recommendations on when and how to incorporate factor scores into MI processes were discussed.
An experimental program for institutionalized older people : a study of response to a volunteer visiting and group recreation program in selected residential institutions for older people.

description: In I960, the Junior League of Vancouver undertook a three-year exploratory program of recreation and visiting activities in selected residential institutions for the aged. The project had been suggested by the Committee on the Welfare of the Aged, a subdivision of the Social Planning Section of the Community Chest and Councils of Greater Vancouver, who were aware of the dearth of diversional resources in these institutions. The Research Department of the Community Chest and Councils of Greater Vancouver was asked by the Advisory Committee to the Junior League Senior Citizens Project to undertake an evaluative study of the program. The present study, a self-contained segment within the broad Research Department evaluation, is designed to test two related hypotheses, (a) that the level of participation in a group recreation program will be positively related to the level of previous participation in group activity, and (b) that the level of participation in a group recreation program will be inversely related to the degree of hearing" impairment. Case material as well as statistical recording is assembled to examine these questions. 34 residents of Taylor Manor, a city-owned and operated boarding home for dependent older men and women, constituted the study sample. There is strong statistical support for the first section of the hypothesis. For the second section, the data are not of statistical significance, possibly because of the limited sample size. However, examination of related factors indicates the question of a relationship between program response and impaired hearing should be considered an open one. Social Contacts is the only other variable identified which seems to have a statistically significant relationship to program response. There was inadequate statistical evidence to support the belief that the program had measurable effect upon attitudes and behaviour of Taylor Manor residents, although subjective observations and trends evident in graphs indicate the program did have positive effect upon a number of participants. A larger population with a matched control sample would be necessary before stronger conclusions could be drawn on whether program participation improved attitudes and behaviour. Some implications for community planning are drawn, and suggestions are made for future research. The possibilities of program development are discussed under four headings: community education, recruitment and training of community volunteers, programming and continuing assessment.
title: Visual Perception in Pre-School Children
Creators: name: Bardwell, Howard Mark
Publisher: name: Utah State University
Year: 1972

description: This study was undertaken to determine if sessions in discrimination tasks with the aid of instructional cues would influence the visual perceptual abilities of pre-school children. The research was conducted in the Child Development Laboratories at Utah State University. Twenty children were used--ten in the experimental group and ten in the control group. The ten children in the experimental group were given training in performing tasks that required ability in visual perception. The ten children in the control group received no such training.
It was found that the ten children who received the individualized instruction scored significantly higher on post-test visual discrimination tasks than did the ten children who received no training. The children who received the training made a significant increase in their perceptive ability. This was indicated by a comparison of beginning test scores with end ing test scores.
There was no significant difference in the visual perception abilities of boys and girls or older and younger children as measured in the visual discriminations tasks.
New Mechanism for Neutrino Mass Generation and Triply Charged Higgs Bosons at the LHC

description: We propose a new mechanism for generating small neutrino masses which predicts the relation m_ν~ v^4/M^3, where v is the electroweak scale, rather than the conventional seesaw formula m_ν~ v^2/M. Such a mass relation is obtained via effective dimension seven operators LLHH(H*H)/M^3, which arise when an isospin 3/2 Higgs multiplet Φis introduced along with iso-triplet leptons. The masses of these particles are naturally in the TeV scale. The neutral member of Φacquires an induced vacuum expectation value and generates neutrino masses, while its triply charged partner provides the smoking gun signal of this scenario. These triply charged bosons can be pair produced at the LHC and the Tevatron, with Φ^{+++} decaying into W^+l^+l^+ or W^+W^+W^+, possibly with displaced vertices. The leptonic decays of Φ^{+++} will help discriminate between normal and inverted hierarchies of neutrino masses. This scenario also allows for raising the standard Higgs boson mass to values in excess of 500 GeV.

description: The efforts of practice sessions in discrimination tasks with the aid of instructional cues were studied to determine their influence on the visual perceptual abilities of pre-school children . The research was conducted at the Utah State University Child Development Laboratories with twenty children. Ten of these children were three years of age and ten were four years of age at the time of the study. Of the twenty children , five boys and five girls, were given training in performing tasks requiring ability in visual perception. The remaining ten children, five boys and five girls, were not given any visual perceptual training.
It was found that the ten children who had received individualized instruction during the practice sessions scored significantly higher on the visual discrimination tasks than the ten children who had received no training. The children made significant improvement through the practice sessions which was indicated by a comparison of the beginning test scores to the ending test scores.
There was a significant difference in the visual perceptual abilities of girls and boys and older and younger children as measured in the visual discrimination tasks.

description: Women have played, and continue to play, a prominent and critical role in conflict resolution and peace-making processes in many different parts of the world. Women in the highlands of Papua New Guinea are no exception. Drawing on my experience as a founding member of Kup Women for Peace, I shall discuss the origins, character and progress of some recent womens initiatives in Simbu Province directed at stopping endemic tribal fighting and building the foundations of a just and sustainable peace. There are two overlapping dimensions: tribal fighting and violence directed against women and girls, which I call gendered violence.
Nanotubes for Particle Channeling, Radiation and Electron Sources
Creators: name: S. Bellucci
Publisher: name: INFN Open Access Repository
Year: 2005

description: Carbon nanotubes consist in graphene sheets rolled into seamless hollow cylinders with diameters ranging from 1 nm to about 50 nm. They have been produced as both single-walled and multi-walled nanotubes. The diameter of the MWNTs typically ranges from 10 to 50 nm, while the length exceeds 10 micron. For SWNTs, the diameter is only 1 nm and the length is up to 100 micron. Nanotubes exhibit unique physical and chemical properties as being a quasi-one dimensional material. The main involvements of the INFN-LNF group in channeling researches are described, i.e. channeling of high energy beams in nanotubes (with the synthesis and characterization of the ordered nanotube samples), crystal extraction and collimation at IHEP (with the design and production of the bent crystals), crystal undulator  R &D (with the characterization of the crystal undulator prototypes with SEM and the positron beam). We consider a precise determination of the optimal experimental conditions for channeling of accelerated particles (protons, positrons, photons, neutrons) through micro- and nano-structured crystals and films of aligned nanotubes, as promising candidates for producing highly focused beams.

Year: 2006

description: For computing of quench propagation in superconducting magnets, a number of material properties from cryogenic to room temperature are necessary. This paper presents the main features (and limitations) of a computer library that provides thermal and electric properties of most used materials in superconducting magnets. Although not complete, the library might be useful to be integrated into suitable custom numerical codes. The library, written in Fortran language, can work also as stand alone and can be interrogated in order to give in output both the required property or tables easy to be plotted.
Q^2 Dependence of Azimuthal Asymmetries in Semi-Inclusive Deep Inelastic Scattering
Creators: name: Salvo, Elvio Di
Publisher: name: INFN Open Access Repository
Year: 2006

description: We study several azimuthal asymmetries in semi-inclusive deep inelastic scattering and in Drell-Yan, interpreting them in the framework of the formalism of the quark correlator, with a particular reference to T-odd functions. The correlator contains an undetermined energy scale, which we fix on the basis of a simple and rather general argument. We find a different value than the one assumed in previous treatments of T-odd functions. This implies different predictions on the $Q^2$ dependence of the above mentioned asymmetries. Our result about the azimuthal asymmetry of unpolarized Drell-Yan agrees with presently available data, contrary to the alternative assumption on the scale. Predictions on other azimuthal asymmetries could be tested against data of planned experiments on Drell-Yan and semi-inclusive deep inelastic scattering.

description: Local or nonlocal character of quantum states can be quantified and is subject to various bounds that can be formulated as complementarity relations. Here, we investigate the local vs. nonlocal character of pure three-qubit states by a four-way interferometer. The complete entanglement in the system can be measured as the entanglement of a specific qubit with the subsystem consisting of the other two qubits. The quantitative complementarity relations are verified experimentally in an NMR quantum information processor.

description: We present a theoretical study of magnetoplasmon spectrum of a two-dimensional electron gas in the presence of Rashba spin-orbit interaction (RSOI), one-dimensional weak electric modulation and a perpendicular magnetic field. The intra-Landau-band magnetoplasmon spectrum is determined in the presence of spin-orbit interaction within the self consistent field approach at finite temperature. Due to Rashba effect, the spin of finite-momentum electrons feels a magnetic field perpendicular to the electron momentum in the inversion plane. The magnetoplasmon spectrum of the modulated two-dimensional electron gas (M2DEG) system is found to exhibit beating of Weiss oscillations due to Rashba effect which is the focus of this work. This effect is absent in the magnetoplasmon spectrum of M2DEG if Rashba spin-orbit interaction is not taken into account. In addition, our finite temperature theory ficilitates analysis of effects of temperature on the magnetoplasmon spectrum of M2DEG in the presence of RSOI. We find that the beating pattern is damped but continues to persist at a finite but low temperature.
