description: Einstein's theory of general relativity predicts that gravitational waves (GWs) are tensor-polarized, with two modes of polarization: plus ($h_+$) and cross ($h_\times$). The unmodeled GW burst analysis pipeline, \textit{BayesWave}, offers two tensor-polarized signal models: the elliptical polarization model ($E$) and the relaxed polarization model ($R$). Future expansion of the global GW detector network will enable more accurate studies of GW polarizations with GW bursts. Here a multi-detector analysis is conducted to compare the performance of $E$ and $R$ in characterizing elliptical and nonelliptical GW polarizations, using nonprecessing and precessing binary black holes (BBHs) respectively as representative synthetic sources. It is found that both models reconstruct the elliptical nonprecessing BBH signals accurately, but $E$ has a higher Bayesian evidence than $R$ as it is has fewer model parameters. The same is true for precessing BBHs that are reconstructed equally well by both models. However, for some events with high precession and especially with three or more detectors, the reconstruction accuracy and evidence of $R$ surpass $E$. The analysis is repeated for BBH events from the third LIGO-Virgo-KAGRA observing run, and the results show that $E$ is preferred over $R$ for existing detections. Although $E$ is generally preferred for its simplicity, it insists on elliptical polarizations, whereas $R$ can measure generic GW polarization content in terms of Stokes parameters. The accuracy of $R$ in recovering polarization content improves as the detector network expands, and the performance is independent of the GW signal morphology.

description: Methyl cyanide is an important trace molecule in star-forming regions. It is one of the more common molecules used to derive kinetic temperatures in such sources. As preparatory work for Herschel, SOFIA, and in particular ALMA we want to improve the rest frequencies of the main as well as minor isotopologs of methyl cyanide. The laboratory rotational spectrum of methyl cyanide in natural isotopic composition has been recorded up to 1.63 THz. Transitions with good signal-to-noise ratio could be identified for CH$_3$CN, $^{13}$CH$_3$CN, CH$_3^{13}$CN, CH$_3$C$^{15}$N, CH$_2$DCN, and $^{13}$CH$_3^{13}$CN in their ground vibrational states up to about 1.2 THz. The main isotopic species could be identified even in the highest frequency spectral recordings around 1.6 THz. The highest $J'$ quantum numbers included in the fit are 64 for $^{13}$CH$_3^{13}$CN and 89 for the main isotopic species. Greatly improved spectroscopic parameters have been obtained by fitting the present data together with previously reported transition frequencies. The present data will be helpful to identify isotopologs of methyl cyanide in the higher frequency bands of instruments such as the recently launched Herschel satellite, the upcoming airplane mission SOFIA or the radio telescope array ALMA.

description: We construct a resonant normal form for an area-preserving map near a generic resonant elliptic fixed point. The normal form is obtained by a simplification of a formal interpolating Hamiltonian. The resonant normal form is unique and therefore provides the formal local classification for area-preserving maps with the elliptic fixed point. The total number of formal invariants is infinite. We consider the cases of weak (of order $n\ge5$) and strong (of order $n=3,4$) resonances. We also construct unique normal forms for analytic families of area-preserving maps. We note that our constructions involve non-linear grading functions.

description: The goal of the ORION task (T3.5) was to support making research funding and performing institutions more permeable to Responsible Research and Innovation principles by encouraging collaboration of ORION partners with stakeholders in the quadruple helix through co-creation approaches. Two projects have been supported through this ORION task; “Virtual Activity Co-Creation Initiative for Novel Engagement” (VACCINE), an online game to engage young members of the public with the science behind infections, immunity and vaccinations, which was a collaboration between Babraham Institute scientists, students from a school in Cambridge and a game developer. The second project, “Melting Pot for ICT in Health Research” (MELTIC), was a collaboration with small isolated communities in Europe to co-create new ideas for ICT in health research and the use of public spaces.

description: We have investigated the polarized images of synchrotron emission from magnetically charged, spherically symmetric regular Bronnikov black hole (in general relativity coupled to nonlinear electrodynamics) and the singular Reissner-Nordström black hole (in general relativity coupled to Maxwell electrodynamics). By taking into account the fact that within the framework of nonlinear electrodynamics, the propagation of the light ray is governed not by the null geodesics of the original spacetime, but rather by the null geodesics associated with the effective metric, we have examined synchrotron radiation characteristics near these black holes at different inclination angles. Our calculations reveal that intensity differences between these two black holes are significant, especially at high values of magnetic charges and large tilt angles. Polarization quantities, such as the electric vector polarization angle ($Δ$EVPA) and normalized intensity difference ($ΔI/I$) show similar trends, driven by lensing, Doppler effects, and redshift, offering insights into black hole metrics.

description: The rotation state of small asteroids is affected by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, which is a net torque caused by solar radiation directly reflected and thermally reemitted from the surface. Due to this effect, the rotation period slowly changes, which can be most easily measured in light curves because the shift in the rotation phase accumulates over time quadratically. We collected archived light curves and carried out new photometric observations for asteroids (10115) 1992 SK, (1620) Geographos, and (1685) Toro. We applied the method of light curve inversion to fit observations with a convex shape model. The YORP effect was modeled as a linear change of the rotation frequency $\upsilon \equiv \mathrm{d}ω/ \mathrm{d}t$ and optimized together with other spin and shape parameters. We detected the acceleration $\upsilon = (8.3 \pm 0.6) \times 10^{-8}\,\mathrm{rad}\,\mathrm{d}^{-2}$ of the rotation for asteroid (10115) 1992 SK. This observed value agrees well with the theoretical value of YORP-induced spin-up computed for our shape and spin model. For (1685) Toro, we obtained $\upsilon = (3.3 \pm 0.3) \times 10^{-9}\,\mathrm{rad}\,\mathrm{d}^{-2}$, which confirms an earlier tentative YORP detection. For (1620) Geographos, we confirmed the previously detected YORP acceleration and derived an updated value of $\upsilon$ with a smaller uncertainty. We also included the effect of solar precession into our inversion algorithm, and we show that there are hints of this effect in Geographos' data. The detected change of the spin rate of (10115) 1992 SK has increased the total number of asteroids with YORP detection to ten. In all ten cases, the $\mathrm{d}ω/ \mathrm{d}t$ value is positive, so the rotation of these asteroids is accelerated. It is unlikely to be just a statistical fluke, but it is probably a real feature that needs to be explained.
Effect of starvation on femoral arterial blood flow determined by the Doppler flowmeter and substrate metabolism in the sheep
Creators: name: Pratt, Robert John
Publisher: name: University of British Columbia
Year: 2010

description: The femoral arterial blood flow in sheep was determined by implanting Doppler cuffs around the vessel which facilitated measurements over a prolonged period of time. Standardization of the cuffs was accomplished with an electronic integrator-digital time counter which converted Doppler frequency shifts to counts per mV/hr from which blood flow was estimated. Metabolic changes occurring in the hind limb of sheep following starvation were studied using femoral arterio-venous concentration differences of metabolites coupled with blood flow. Indwelling catheters were introduced into the femoral artery and vein to enable blood sampling. Two series of experiments were carried out in this study. Experiment I involved a four day starvation of two ewes. There was no statistical difference in the femoral arterial blood flow between fed and starved animals. In Experiment II another animal was utilized for four trials with the duration of starvation increased from four to six days. The adjusted mean fed blood flow of 78 + 2 ml/min decreased to a minimum of 45 + 3 ml/min on the sixth day of starvation. The average blood flow during the six days of starvation was 23.5 per cent lower than the pre-starvation level (P 0.05). The Doppler Flowmeter offers definite advantages over other methods of blood flow determinations by facilitating the measurement over prolonged periods without causing excitement of the animals. In this study the use of the Doppler Flowmeter and the continuous monitoring of blood flow through a period of 11 days has demonstrated that hind limb blood flow is reduced during starvation. The utilization of glucose and lactate was reduced during starvation by 62 and 39% respectively. There was a net production of 25 ± 1.5 and 20 ± 1 pg/min of alanine on the fifth and sixth days of starvation versus a net utilization of 23 ± 2 pig/min prior to starvation. The net alanine production during starvation provides a precursor for gluconeogenesis.

description: In research articles and patents several methods have been proposed for the extraction of zero-point energy from the vacuum. None of the proposals have been reliably demonstrated, yet they remain largely unchallenged. In this paper the underlying thermodynamics principles of equilibrium, detailed balance, and conservation laws are presented for zero-point energy extraction. The proposed methods are separated into three classes: nonlinear processing of the zero-point field, mechanical extraction using Casimir cavities, and the pumping of atoms through Casimir cavities. The first two approaches are shown to violate thermodynamics principles, and therefore appear not to be feasible, no matter how innovative their execution. The third approach, based upon stochastic electrodynamics, does not appear to violate these principles, but may face other obstacles. Initial experimental results are tantalizing but, given the lower than expected power output, inconclusive.

description: To study stars analogous to those in the early Universe with redshift z > 3, we need to probe environments with low metallicities. Until recently, massive O-type stars with metallicities lower than that of the Small Magellanic Cloud (SMC, Z < 20%Z_sol) were only known in compact dwarf galaxies. Observations of stars in such distant galaxies (> 1 Mpc) suffer from limited S/N ratios and spatial resolution. Recently, a few O-type stars were identified in the nearby Magellanic Bridge which offers a unique laboratory with low gas density and metal content. We acquired high-resolution HST-COS FUV spectra of two O-type stars in the Magellanic Bridge. Using the UV forest of iron lines from these observations, we aim to precisely measure the inherent iron abundances and determine the metallicity of the stars. Using detailed expanding non-LTE atmosphere models, we generate synthetic spectra for different iron abundances and for a range of microturbulent velocities. We use Bayesian posterior sampling to measure the iron abundance and compute uncertainties based on the possible range of microturbulent velocities.
 The O stars in the Magellanic Bridge have severely sub-SMC Fe abundances, reaching as low as 10.8% and 3.6% Fe_sol. The most Fe-deficient star also shows alpha-enhancement. These stars are the nearest extremely metal-poor O stars discovered to date. Our finding marks the first robust determination of O-star iron abundances in a metallicity regime comparable to dwarf galaxies like Sextans A and Leo P. The iron abundances of the stars do not correlate with their oxygen abundances. Our results highlight the problem of using oxygen-based metallicities. The proximity of the stars in the Bridge combined with their different abundance patterns underlines that the ISM of the Magellanic Bridge must be highly inhomogeneous and is not properly mixed.

Carroll contractions of Lorentz-invariant theories

description: We consider Carroll-invariant limits of Lorentz-invariant field theories. We show that just as in the case of electromagnetism, there are two inequivalent limits, one "electric" and the other "magnetic". Each can be obtained from the corresponding Lorentz-invariant theory written in Hamiltonian form through the same "contraction" procedure of taking the ultrarelativistic limit $c \rightarrow 0$ where $c$ is the speed of light, but with two different consistent rescalings of the canonical variables. This procedure can be applied to general Lorentz-invariant theories ($p$-form gauge fields, higher spin free theories etc) and has the advantage of providing explicitly an action principle from which the electrically-contracted or magnetically-contracted dynamics follow (and not just the equations of motion). Even though not manifestly so, this Hamiltonian action principle is shown to be Carroll invariant. In the case of $p$-forms, we construct explicitly an equivalent manifestly Carroll-invariant action principle for each Carroll contraction. While the manifestly covariant variational description of the electric contraction is rather direct, the one for the magnetic contraction is more subtle and involves an additional pure gauge field, whose elimination modifies the Carroll transformations of the fields. We also treat gravity, which constitutes one of the main motivations of our study, and for which we provide the two different contractions in Hamiltonian form.

description: The magnetic properties of graphene on finite geometries are studied using a self-consistent mean-field theory of the Hubbard model. This approach is known to predict ferromagnetic edge states close to the zig-zag edges in single-layer graphene quantum dots and nanoribbons. In order to assess the accuracy of this method, we perform complementary exact diagonalization and quantum Monte Carlo simulations. We observe good quantitative agreement for all quantities investigated provided that the Coulomb interaction is not too strong.

description: The angular dependence (x-ray linear dichroism) of the Cr K pre-edge in MgAl2O4:Cr3+ spinel is measured by means of x-ray absorption near edge structure spectroscopy (XANES) and compared to calculations based on density functional theory (DFT) and ligand field multiplet theory (LFM). We also present an efficient method, based on symmetry considerations, to compute the dichroism of the cubic crystal starting from the dichroism of a single substitutional site. DFT shows that the electric dipole transitions do not contribute to the features visible in the pre-edge and provides a clear vision of the assignment of the 1s-->3d transitions. However, DFT is unable to reproduce quantitatively the angular dependence of the pre-edge, which is, on the other side, well reproduced by LFM calculations. The most relevant factors determining the dichroism of Cr K pre-edge are identified as the site distortion and 3d-3d electronic repulsion. From this combined DFT, LFM approach is concluded that when the pre-edge features are more intense than 4 % of the edge jump, pure quadrupole transitions cannot explain alone the origin of the pre-edge. Finally, the shape of the dichroic signal is more sensitive than the isotropic spectrum to the trigonal distortion of the substitutional site. This suggests the possibility to obtain quantitative information on site distortion from the x-ray linear dichroism by performing angular dependent measurements on single crystals.

description: Algorithms to simulate the ring-exchange models using the projected entangled pair states (PEPS) are developed. We generalize the imaginary time evolution (ITE) method to optimize PEPS wave functions for the models with ring-exchange interactions. We compare the effects of different approximations to the environment. To understand the numerical instability during the optimization, we introduce the ``singularity'' of a PEPS and develop a regulation procedure that can effectively reduce the singularity of a PEPS. We benchmark our method with the toric code model, and obtain extremely accurate ground state energies and topological entanglement entropy. We also benchmark our method with the two-dimensional cyclic ring exchange model, and find that the ground state has a strong vector chiral order. The algorithms can be a powerful tool to investigate the models with ring interactions. The methods developed in this work, e.g., the regularization process to reduce the singularity can also be applied to other models.
title: Investigations into Mapping Lava Flows in the Snake River Plain, Idaho
Creators: name: Hobson-Broko, Vinita Ruth
Publisher: name: Utah State University
Year: 2009

description: The origin of the Snake River plain continues to be debated, but the plume model is most popular at the current time. Some theories, such as meteorite impact, have been excluded, but the remaining theories require more scrutiny.
Various methods of examining phenomena in the Snake River Plain were employed. Unsupervised classification of Landsat ETM data indicates that spectra can be used to differentiate between flows. However, photographs of flows at Craters of the Moon National Monument show wide variations in texture and color within a single flow. Vegetation grows preferentially on the smoother pahoehoe slabs and significantly impacting the spectra observed through remote sensing. Additional vegetation would prohibit using Landsat ETM to map lava flows reliably. Landsat ETM is not a viable method to map the lava flows in quadrangles Twin Falls NE, Hunt, and Eden NE, since they have significantly more loess and vegetative cover.
Elevation data reveal the locations of the ramparts at the source vent, but do not define the edge of a flow except when an inflated lobe terminates the flow. Field observations of terrain and geochemical analysis of samples defines the flows and their source vent.

description: In pursuit of detecting unstinted objects that extend beyond predefined categories, prior arts of open-vocabulary object detection (OVD) typically resort to pretrained vision-language models (VLMs) for base-to-novel category generalization. However, to mitigate the misalignment between upstream image-text pretraining and downstream region-level perception, additional supervisions are indispensable, eg, image-text pairs or pseudo annotations generated via self-training strategies. In this work, we propose CCKT-Det trained without any extra supervision. The proposed framework constructs a cyclic and dynamic knowledge transfer from language queries and visual region features extracted from VLMs, which forces the detector to closely align with the visual-semantic space of VLMs. Specifically, 1) we prefilter and inject semantic priors to guide the learning of queries, and 2) introduce a regional contrastive loss to improve the awareness of queries on novel objects. CCKT-Det can consistently improve performance as the scale of VLMs increases, all while requiring the detector at a moderate level of computation overhead. Comprehensive experimental results demonstrate that our method achieves performance gain of +2.9% and +10.2% AP50 over previous state-of-the-arts on the challenging COCO benchmark, both without and with a stronger teacher model.

description: One of the most widely discussed features of the cuprate high Tc superconductors is the presence of a pseudogap in the normal state. Recent transport and specific heat measurements have revealed an abrupt transition at the pseudogap critical point, denoted p*, characterized by a drop in carrier density and a strong mass enhancement. In order to give more details about this transition at p*, we performed low-temperature infrared spectroscopy in the normal state of cuprate superconductors La2-xSrxCuO4 (LSCO) and La1.8-xEu0.2SrxCuO4 (Eu-LSCO) for doping contents across the pseudogap critical point p* (from p = 0.12 to 0.24). Through the complex optical conductivity we can extract the spectral weight, K*, of the narrow Drude peak due the coherent motion of the quasi-particles, and the spectral weight enclosed inside the mid-infrared (MIR) band, KMIR, caused by coupling of the quasi-particles to collective excitations of the many-body system. K* is smaller than a third of the value predicted by band calculations, and KMIR forms a dome as a function of doping. We observe a smooth doping dependence of K* through p*, and demonstrate that this is consistent with the observed doping dependence of the carrier density and the mass enhancement. We argue that the superconducting dome is the result of the confluence of two opposite trends, namely the increase of the density of the quasi-particles and the decrease of their coupling to the collective excitations as a function of doping.

Maternal influences on size in the Cinnabar moth
Creators: name: Richards, Laura Jean
Publisher: name: University of British Columbia
Year: 2010

description: Genetic and non-genetic effects of maternal; size were investigated in four introduced populations of Cinnabar moth Tyria jacobaeae (L.) (Arctiidae). Offspring of different female moths were reared to the pupal stage under greenhouse conditions with an overabundance of food. Mean offspring-maternal size correlations were highest for second generation laboratory offspring using pupal weight as the size criterion, maximum egg weight was not related to female size, although average egg weight tended to decrease, and fecundity increase with female wing length. Egg weight was not related to final pupal weight. Egg weight decreased over the oviposition period, but pupae reared from later batches were not consistently of lower weight when compared with pupae reared from batches laid on tie first day of oviposition. Under a less favorable temperature regime, hatching, success was reduced in later batches. It was concluded that maternal effects (genetic and non-genetic) on offspring size are unimportant under normal field conditions in comparison to the effects exerted by larval crowding and food availability. However under very poor conditions, selective mortality may be imposed on later batches, or on the lighter eggs of large moths.

description: Spiral jets are impulsive plasma ejections that typically show an apparent rotation motion. Their generation, however, is still nont understood thoroughly. Based on a high-resolution vector magnetogram form the Polarimetric and Helioseismic Imager onboard Solar Orbiter, we constrcut a data-constrained three-dimensional (3D) MHD model, aiming to disclose the eruption mechanism of a tiny spiral jet at a moss region observed on March 3 2022. The initial configuration of the simulation consists of an extrapolated coronal magnetic field based on the vector magnetogram and an inserted unstable flux rope constructed by the Regularized Biot-Savart Laws method. Our results highlight the critical role of the fan-spine configuration in forming the spiral jet and confirm the collapse of the pre-existing magnetic null to a curved 3D current sheet where external reconnection takes places. It is further disclosed that the flux rope quickly moves upward, reconnecting with the field lines near the outer spine, thereby enabling the transfer of twist and cool material from the flux rope to the open field, giving rise to the tiny spiral jet we observed. The notable similarities between these characteristics and those for larger-scale jets suggest that spiral jets, regardless of their scale, essentially share the same eruption mechanism.

description: This paper summarizes our participation in the SMART Task of the ISWC 2020 Challenge. A particular question we are interested in answering is how well neural methods, and specifically transformer models, such as BERT, perform on the answer type prediction task compared to traditional approaches. Our main finding is that coarse-grained answer types can be identified effectively with standard text classification methods, with over 95% accuracy, and BERT can bring only marginal improvements. For fine-grained type detection, on the other hand, BERT clearly outperforms previous retrieval-based approaches.

description: The Habitable Worlds Observatory (HWO) will enable a transformative leap in the direct imaging and characterization of Earth-like exoplanets. For this, NASA is focusing on early investment in technology development prior to mission definition and actively seeking international partnerships earlier than for previous missions. The "R&D for Space-Based HCI in Europe" workshop, held in March 2024 at Paris Observatory, convened leading experts in high-contrast imaging (HCI) to discuss European expertise and explore potential strategies for European contributions to HWO. This paper synthesizes the discussions and outcomes of the workshop, highlighting Europe's critical contributions to past and current HCI efforts, the synergies between ground- and space-based technologies, and the importance of laboratory testbeds and collaborative funding mechanisms.
 Key conclusions include the need for Europe to invest in technology development for areas such as deformable mirrors and advanced detectors, and establish or enhance laboratory facilities for system-level testing. Putting emphasis on the urgency of aligning with the timeline of the HWO, the participants called on an open affirmation by the European Space Agency (ESA) that a European contribution to HWO is clearly anticipated, to signal national agencies and unlock funding opportunities at the national level. Based on the expertise demonstrated through R&D, Europe is poised to play a pivotal role in advancing global HCI capabilities, contributing to the characterization of temperate exoplanets and fostering innovation across domains.

title: Survey of NCAA Athletic Trainers’ Administration of the National Wrestling Coaches Association Weight Certification Program
Creators: name: Konrath, Samuel
Publisher: name: Utah State University
Year: 2021

description: Context: The National Collegiate Athletic Association (NCAA) implemented a minimum weight certification program in 1997 to help protect wrestlers from dangerous weight loss practices. Despite nearly a quarter of a century of this program, there is no published research detailing the implementation of it.
Objective: Determine how the NCAA minimum weight certification is being implemented across Division I programs.
Design: Cross-sectional study
Setting: Survey
Patients or Other Participants: A total of 35 (45.5%) of 77 NCAA division I wrestling athletic trainers responded to the survey.
Main Outcome Measure(s): Survey data on how the NCAA minimum weight certification program was implemented at the division I level was collected.
Results: Nearly all respondents used athletic trainers to take their measurements. Most staff (74.3%) had five or more years of experience taking the measurements, and only one (2.9%) had less than a year of experience. The time prior to competition that the measurement was taken ranged widely from 2 to 110 days. Nearly all (97.1%) used skinfold calipers, and just one program (2.9%) specified a different method, iDXA scan. Of those using the skinfold calipers, 52.9% used Lange calipers and 32.4% did not know the caliper type. Everyone used the same three measurement locations. Body density was converted to %BF with the Brozek formula at 13% of the institutions, the Siri formula at 4.3% of programs, “other” (defined by respondents as the optimal performance calculator provided by the NWCA) at 13% of schools, and 69.6% did not know.
Conclusion: Overall, there appears to be great consistency in the administration of the minimal wrestling weight standards across NCAA Division I wrestling programs.
Progressive Human Motion Generation Based on Text and Few Motion Frames

description: Although existing text-to-motion (T2M) methods can produce realistic human motion from text description, it is still difficult to align the generated motion with the desired postures since using text alone is insufficient for precisely describing diverse postures. To achieve more controllable generation, an intuitive way is to allow the user to input a few motion frames describing precise desired postures. Thus, we explore a new Text-Frame-to-Motion (TF2M) generation task that aims to generate motions from text and very few given frames. Intuitively, the closer a frame is to a given frame, the lower the uncertainty of this frame is when conditioned on this given frame. Hence, we propose a novel Progressive Motion Generation (PMG) method to progressively generate a motion from the frames with low uncertainty to those with high uncertainty in multiple stages. During each stage, new frames are generated by a Text-Frame Guided Generator conditioned on frame-aware semantics of the text, given frames, and frames generated in previous stages. Additionally, to alleviate the train-test gap caused by multi-stage accumulation of incorrectly generated frames during testing, we propose a Pseudo-frame Replacement Strategy for training. Experimental results show that our PMG outperforms existing T2M generation methods by a large margin with even one given frame, validating the effectiveness of our PMG.

description: Hyperspectral imaging has been increasingly used for underwater survey applications over the past years. As many hyperspectral cameras work as push-broom scanners, their use is usually limited to the creation of photo-mosaics based on a flat surface approximation and by interpolating the camera pose from dead-reckoning navigation. Yet, because of drift in the navigation and the mostly wrong flat surface assumption, the quality of the obtained photo-mosaics is often too low to support adequate analysis.In this paper we present an initial method for creating hyperspectral 3D reconstructions of underwater environments. By fusing the data gathered by a classical RGB camera, an inertial navigation system and a hyperspectral push-broom camera, we show that the proposed method creates highly accurate 3D reconstructions with hyperspectral textures. We propose to combine techniques from simultaneous localization and mapping, structure-from-motion and 3D reconstruction and advantageously use them to create 3D models with hyperspectral texture, allowing us to overcome the flat surface assumption and the classical limitation of dead-reckoning navigation.

title: Utah Middle-Level School Community Councils: An Evaluation of Compliance, Processes, and Perceived Impact
Creators: name: Nygaard, Richard Jackson

description: The historical perspective of schools in our democratic society provides a framework of tension between local parent and community control and professional and state control of public school decisions. Today, federal and state requirements demand increased student achievement. One school reform effort enlisted to help meet the challenges is the creation of site-based decision-making councils that involve school administrators, teachers and parents. The state of Utah requires each public school to have a School Community Council that is responsible for the development of plans for school improvement. Limited funds are provided to each School Community Council through the School LAND Trust Program. The funds are to be used to assist in the implementation of the developed plans for the purpose of increased student achievement. Three Utah Middle level SCCs participated in this qualitative strength-based process evaluation. Two of the SCCs were identified as exemplary, and the third SCC was just beginning to function as an SCC. Based on the three questions guiding the evaluation, the evaluation learned that SCCs identified as exemplary were compliant with the law, employed strategies identified in the literature for effective site-based decision-making, and implemented plans that were perceived to impact student achievement. In addition, themes emerged from the strength-based approach to learn what SCC processes influenced an effective balance between the professional expertise and the democratic involvement in decision-making. The emergent themes deal with processes related to membership and elections, sources of confidence, use of data to drive school improvement decision, and communication.
