description: Computing an array of all pairs of geodesic distances between the pixels of an image is time consuming. In the sequel, we introduce new methods exploiting the redundancy of geodesic propagations and compare them to an existing one. We show that our method in which the source point of geodesic propagations is chosen according to its minimum number of distances to the other points, improves the previous method up to 32% and the naive method up to 50% in terms of reduction of the number of operations.

description: A comparison between the oscillation frequencies of six multi-periodic Delta Scuti stars of the Pleiades cluster and the eigenfrequencies of rotating stellar models that match the corresponding stellar parameters has been carried out. The assumption that all the stars considered have some common parameters, such as metallicity, distance or age, is imposed as a constraint. As a result, we have a best fit solution associated with a cluster metallicity of [Fe/H] ~ 0.067, an age between 70x10^6 and 100x10^6 yr and a distance modulus of mv-Mv=5.60-5.70 mag. All the stars were found to oscillate mainly in non-radial, low degree, low order p modes. Estimates of mass and rotation rates for each star are also obtained

description: We perform a comparative study of applicability of the Multifractal Detrended Fluctuation Analysis (MFDFA) and the Wavelet Transform Modulus Maxima (WTMM) method in proper detecting of mono- and multifractal character of data. We quantify the performance of both methods by using different sorts of artificial signals generated according to a few well-known exactly soluble mathematical models: monofractal fractional Brownian motion, bifractal Levy flights, and different sorts of multifractal binomial cascades. Our results show that in majority of situations in which one does not know a priori the fractal properties of a process, choosing MFDFA should be recommended. In particular, WTMM gives biased outcomes for the fractional Brownian motion with different values of Hurst exponent, indicating spurious multifractality. In some cases WTMM can also give different results if one applies different wavelets. We do not exclude using WTMM in real data analysis, but it occurs that while one may apply MFDFA in a more automatic fashion, WTMM has to be applied with care. In the second part of our work, we perform an analogous analysis on empirical data coming from the American and from the German stock market. For this data both methods detect rich multifractality in terms of broad f(alpha), but MFDFA suggests that this multifractality is poorer than in the case of WTMM.

description: In the framework of the Chandrasekhar-mass deflagration model for Type Ia supernovae (SNe Ia), a persisting free parameter is the initial morphology of the flame front, which is linked to the ignition process in the progenitor white dwarf. Previous analytical models indicate that the thermal runaway is driven by temperature perturbations (''bubbles'') that develop in the white dwarf's convective core. In order to probe the conditions at ignition (diameters, temperatures and evolutionary timescales), we have performed hydrodynamical 2D simulations of buoyant bubbles in white dwarf interiors. Our results show that fragmentation occurring during the bubble rise affects the outcome of the bubble evolution. Possible implications for the ignition process of SNe Ia are discussed.

description: Real applications of natural language document processing are very often confronted with domain specific lexical gaps during the analysis of documents of a new domain. This paper describes an approach for the derivation of domain specific concepts for the extension of an existing ontology. As resources we need an initial ontology and a partially processed corpus of a domain. We exploit the specific characteristic of the sublanguage in the corpus. Our approach is based on syntactical structures (noun phrases) and compound analyses to extract information required for the extension of GermaNet's lexical resources.

description: Consider $L$ a regular Lagrangian, $S$ the canonical semispray, and $h$ the horizontal projector of the canonical nonlinear connection. We prove that if the Lagrangian is constant along the integral curves of the Euler-Lagrange equations then it is constant along the horizontal curves of the canonical nonlinear connection. In other words $S(L)=0$ implies $d_hL=0$. If the Lagrangian $L$ is homogeneous of order $k\neq 1$ then $L$ is a conservation law and hence $d_hL=0$. We give an example of nonhomogeneous Lagrangians for which $d_hL\neq 0$.

description: Aplectana membranosa is a nematode (Cosmocercidae) that is widely distributed in the neotropics (Campião et al. 2014. Zootaxa 1:1–19). The Cosmocercidae are mainly parasites of vertebrates (Vanderburgh and Anderson 1987. Can. J. Zool. 65:1650–1661), and have been described from the gastrointestinal systems of anurans (Campião et al. 2014, op. cit.; Alcantara et al. 2018. J. Parasitol. 104:550–556; Teles et al. 2018b. Comp. Parasitol. 85:208–211). The genus Proceratophrys is composed of 41 species of frogs from Brazil, Argentina, and Paraguay (Frost 2018. Amphibian Species of the World: an Online Reference. Version 6.1; accessed 16 June 2018. Electronic database accessible at https:amphibiansoftheworld.amnh.org). Proceratophrys aridus (Fig. 1) inhabits the Caatinga ecoregion. In the present study, we analyzed a specimen of P. aridus (SVL = 42.5 mm) captured in the municipality of Várzea Alegre, northeast Brazil (6.86944ºS, 39.385ºW, WGS 84; 297 m elev.) on 13 March 2018. It was anesthetized intramuscularly and then euthanized with intravenous potassium chloride. The body cavity, respiratory system, and gastrointestinal tract were examined for endoparasites using a stereomicroscope. The recorded nematodes were counted, preserved in 70% alcohol, mounted on slides, and identified with the aid of an optical microscope. We found 235 Aplectana membranosa in the small intestine. This is the first record of A. membranosa infecting P. aridus. Aplectana membranosa was originally described from Leptodactylus latrans (Leptodactylidae) and has also been recorded in the following species: Ischnocnema parva, L. mystaceus, L. lineatus, L. pentadactylus, L. rugosus, L. vastus, Odontophrynus americanus, Rhinella granulosa, R. guttatus, R. icterica, R. marina, R. jimi, and R. diptycha (Campião et al. 2014, op. cit.). It has a direct life cycle and a high reproductive rate, which facilitates the propagation of its larvae in the environment. Infection occurs through the skin or by accidental ingestion of eggs or larvae (Anderson 2000. Nematode Parasites of Vertebrates: Their Development and Transmission, 2nd ed. CABI Publishing, Wallingford, Oxon, UK. 650 pp.). These parasites are of great biological importance in the trophic relationships and conservation studies of their host populations (Marcogliese 2005. Int. J. Parasitol. 35:705–716). Several studies reporting endoparasites in anurans have been conducted in the last decade (Anjos 2011. Neotropical Helminthol. 5:107–111; Teles et al. 2014. Herpetol. Notes 7:355–356; Teles et al. 2015. J. Biol. 75:251–253), but about 90% of anuran species in Brazil have not been investigated for parasites (Campião et al. 2014, op. cit.). Such studies investigating the parasitic associates of anurans, like P. aridus, would provide important data for future studies related to both parasitology and the ecology of these amphibians.

description: Energy dissipation in water is very fast and more efficient than in many other liquids. This behavior is commonly attributed to the intermolecular interactions associated with hydrogen bonding. Here, we investigate the dynamic energy flow in the hydrogen bond network of liquid water by a pump-probe experiment. We resonantly excite intermolecular degrees of freedom with ultrashort single-cycle terahertz pulses and monitor its Raman response. By using ultrathin sample cell windows, a background-free bipolar signal whose tail relaxes monoexponentially is obtained. The relaxation is attributed to the molecular translational motions, using complementary experiments, force field, and ab initio molecular dynamics simulations. They reveal an initial coupling of the terahertz electric field to the molecular rotational degrees of freedom whose energy is rapidly transferred, within the excitation pulse duration, to the restricted translational motion of neighboring molecules. This rapid energy transfer may be rationalized by the strong anharmonicity of the intermolecular interactions.

description: We point out that a spatially-varying electric field can be used to cancel the effect of gravity in liquid mixtures by coupling to the different components' permittivities. Cancellation occurs if the system under consideration is small enough. For a simple ``wedge'' electrode geometry we show that the required system size and voltage are practical, easily realizable in the Lab. Thus this setup might be a simple alternative to more expensive or hazardous options such as the space-shuttle, drop-tower, or magnetic levitation experiments.

description: We present an analysis of the dynamics of a nanomechanical resonator coupled to a superconducting single electron transistor (SSET) in the vicinity of the Josephson quasiparticle (JQP) and double Josephson quasiparticle (DJQP) resonances. For weak coupling and wide separation of dynamical timescales, we find that for either superconducting resonance the dynamics of the resonator is given by a Fokker-Planck equation, i.e., the SSET behaves effectively as an equilibrium heat bath, characterised by an effective temperature, which also damps the resonator and renormalizes its frequency. Depending on the gate and drain-source voltage bias points with respect to the superconducting resonance, the SSET can also give rise to an instability in the mechanical resonator marked by negative damping and temperature within the appropriate Fokker-Planck equation. Furthermore, sufficiently close to a resonance, we find that the Fokker-Planck description breaks down. We also point out that there is a close analogy between coupling a nanomechanical resonator to a SSET in the vicinity of the JQP resonance and Doppler cooling of atoms by means of lasers.

description: The nonlinear propagation of low-frequency circularly polarized waves in a magnetized dusty plasma is analyzed. It is found that wave steepening and shock formation can take place due to the presence of nonlinear quantum vacuum effects, thus giving rise to ultra-intense electromagnetic shocks. Moreover, it is shown that solitary wave structures are admitted even under moderate astrophysical conditions. The results may have applications to astrophysical plasmas, as well as next generation laser interactions with laboratory plasmas containing dust clusters.

description: During the eukaryotic cell cycle, chromatin undergoes several conformational changes, which are believed to play key roles in gene expression regulation during interphase, and in genome replication and division during mitosis. In this paper, we propose a scenario for chromatin structural reorganization during mitosis, which bridges all the different scales involved in chromatin architecture, from nucleosomes to chromatin loops. We build a model for chromatin, based on available data, taking into account both physical and topological constraints DNA has to deal with. Our results suggest that the mitotic chromosome condensation/decondensation process is induced by a structural change at the level of the nucleosome itself.

description: We present a three-dimensional kinematic reconstruction of the optically-emitting, oxygen-rich ejecta of supernova remnant N132D in the Large Magellanic Cloud. Data were obtained with the 6.5 m Magellan telescope in combination with the IMACS+GISMO instrument and survey [O III] $λλ$4959,5007 line emission in a ${\sim}$3$^{\prime}~\times$ 3$^{\prime}$ region centered on N132D. The spatial and spectral resolution of our data enable detailed examination of the optical ejecta structure. The majority of N132D's optically bright oxygen ejecta are arranged in a torus-like geometry tilted approximately 28$^{\circ}$ with respect to the plane of the sky. The torus has a radius of 4.4 pc ($D_{\rm LMC}$/50 kpc), exhibits a blue-shifted radial velocity asymmetry of $-3000$ to $+2300$ km s$^{-1}$, and has a conspicuous break in its circumference. Assuming homologous expansion from the geometric center of O-rich filaments, the average expansion velocity of 1745 km s$^{-1}$ translates to an age since explosion of 2450 $\pm$ 195 yr. A faint, spatially-separated "runaway knot" (RK) with total space velocity of 3650 km s$^{-1}$ is nearly perpendicular to the torus plane and coincident with X-ray emission that is substantially enhanced in Si relative to the LMC and N132D's bulk ejecta. These kinematic and chemical signatures suggest that the RK may have had its origin deep within the progenitor star. Overall, the main shell morphology and high-velocity, Si-enriched components of N132D have remarkable similarity with that of Cassiopeia A, which was the result of a Type IIb supernova explosion. Our results underscore the need for further observations and simulations that can robustly reconcile whether the observed morphology is dominated by explosion dynamics or shaped by interaction with the environment.

description: In this Case Study, the COGMCI Software is used to discusses (i) the best size of an engine CHP system and (ii) what the efficiency indicators tell us about the system performance? Which is the best performance indicator? To start the discussion, COGMCI software is used to simulate and predict the performance of ten different engine CHP case studies for a mall supposed to be located in New York (8760 hours analysis). The building energy demand is predicted using the EnergyPlus software and the results (building energy consumption) are used as COGMCI software input. Engine CHP is an important technology in the migration from fossil fuels to renewables. Every site with coincident electrical and thermal demands is a CHP candidate and has an annual energy savings opportunity (CHP potential). COGMCI can help you size and define the better configuration no matter what your main goal is (i) payback, (ii) grid independence, (iii) CO2 emissions reduction, or (iv) a combination of them. The study reveals that engine CHP can save up to 40% primary energy when using the harmonized reference conversion efficiency defined at the EU 2015/2402 directive and a high-efficiency electrical chillers COP.

description: Absorption spectra of liquid water at 300 K are calculated from both classical and density functional theory molecular dynamics simulation data, which together span from 1 MHz to hundreds of THz, agreeing well with experimental data qualitatively and quantitatively over the entire range, including the IR modes, the microwave peak, and the intermediate THz bands. The spectra are decomposed into single-molecular and collective components, as well as into components due to molecular reorientations and changes in induced molecular dipole moments. These decompositions shed light on the motions underlying the librational and translational (hydrogen-bond stretching) bands at 20 and 5 THz, respectively; interactions between donor protons and acceptor lone pair electrons are shown to be important for the line shape in both librational and translational regimes, and in- and out-of-phase librational dimer modes are observed and explored.

description: Thermal radiation of photons and dileptons from hadronic matter plays an essential role in understanding electromagnetic emission spectra in high-energy heavy-ion collisions. In particular, baryons and anti-baryons have been found to be strong catalysts for electromagnetic radiation, even at collider energies where the baryon chemical potential is small. Here, we conduct a systematic analysis of $π$- and $ω$-meson-induced reactions off a large set of baryon states. The interactions are based on effective hadronic Lagrangians where the parameters are quantitatively constrained by empirical information from vacuum decay branchings and scattering data, and gauge invariance is maintained by suitable regularization procedures. The thermal emission rates are computed using kinetic theory but can be directly compared to previous calculations using hadronic many-body theory. The comparison to existing calculations in the literature reveals our newly identified contributions to be rather significant.

description: Exciting results from the Relativistic Heavy Ion Collider (RHIC) have been presented at this Workshop. However, fundamental questions remain to be addressed in the future regarding whether the system is deconfined, chiral symmetry is restored, a color glass condensate exists in the initial state, and how the system evolves through eventual hadronization. Jets, heavy flavors and electromagnetic probes are sensitive to the initial high density stage of RHIC collisions, and should provide new insight. Significant additional capabilities will be added with a luminosity upgrade of RHIC (to RHIC II), upgrades of present detectors and a possible, new comprehensive detector at RHIC II.

description: The following report is generated within the iQonic project, which concentrates on the development of micro-optic assemblies. The project target is to create a scalable zero-defect platform that employs flexible and sustainable assembly practices and technologies for micro-optics. The iQonic platform will be implemented using a holistic approach with eight strategies (DIAGNOSE, ADJUST, PREDICT, DETECT, PREVENT, MANAGE, SUSTAIN, REDESIGN), involving several different technologies from different branches of engineering and science. These technologies are described and benchmarked in this report with respect to the application fields of the project. The iQonic consortium will test the developed platform with four uses cases before the end of the project. These use cases are briefly described and linked to the iQonic technologies in this report. The mapping shows how each technology will be demonstrated and how the possible improvements to the state-of-the-art (SoA) can be seen in the end of the project. Moreover, the report considers the SoA of commonly known and widely accepted micro-optic assembly processes and in situ measurements used in the assembly processes.
 The SoA analysis of the report points out that the project incorporates technologies, which are not used in the quality control of either manufacturing industry or micro-optics. iQonic also contains many technologies that have been used in somewhere else in the manufacturing industry, but are rare or have not been applied to photonic assemblies. In addition, the report shows that iQonic consortium will introduce new advanced features to technologies that already exist in the field. Due to the advances of the SoA by each iQonic technology in the field of micro-optics, the consortium will deliver a unique solution in the field of micro-optics where no similar multidisciplinary solution exists.

description: Key demographic trends in the rural South over the next decade-the aging of the population as baby boomers enter retirement, continued migration to the South, and rapid increases in shares of Hispanic residents-may have profound consequences for the financing of rural community public services. In this paper, we provide an overview of demographic and economic trends that are expected to influence the ability of rural communities to provide essential public services. In addition, we provide econometric evidence on the impacts that these trends are likely to have on the financing of K-12 education in South Carolina.

description: This paper examines trends in the socioeconomic well-being in rural counties where Black residents represent one third or more of the population. These racially diverse rural counties (RDRCs) are located exclusively in the rural South and generally have low levels of economic well-being. On a positive note, college education levels in RDRCs are found to have increased rapidly between 1990 and 2000. Regression analysis suggests that these increases were in part due to the concentration of Historically Black Colleges and Universities in the region. Local investments in K-12 education are also found to be linked to county education levels.

description: In 1991, the Intermodal Surface Transportation Efficiency Act (ISTEA) changed the federal-state transportation relationship by devolving decision making to the states. In turn, states were required to work with local officials on transportation improvements. ISTEA was authorized for 1992-1997, and the Transportation Equity Act for the 21st Century continued ISTEA policies through 2003. Changes in road and bridge conditions in the rural south are examined under these new transportation policies. Federal funding trends are detailed with state funding. Overall condition of roads and bridges eligible for federal funding improved, traffic increased on all roads, but condition disparities between local roads and federally funded roads grew.

description: The Galactic center black hole candidate Sgr A* is the best target for studies of low-luminosity accretion physics, including with near-infrared and submillimeter wavelength long baseline interferometry experiments. Here we compare images and spectra generated from a parameter survey of general relativistic MHD simulations to a set of radio to near-infrared observations of Sgr A*. Our models span the limits of weak and strong magnetization and use a range of sub-grid prescriptions for electron heating. We find two classes of scenarios can explain the broad shape of the submillimeter spectral peak and the highly variable near-infrared flaring emission. Weakly magnetized "disk-jet" models where most of the emission is produced near the jet wall, consistent with past work, as well as strongly magnetized (magnetically arrested disk) models where hot electrons are present everywhere. Disk-jet models are strongly depolarized at submillimeter wavelengths as a result of strong Faraday rotation, inconsistent with observations of Sgr A*. We instead favor the strongly magnetized models, which provide a good description of the median and highly variable linear polarization signal. The same models can also explain the observed mean Faraday rotation measure and potentially the polarization signals seen recently in Sgr A* near-infrared flares.

description: Workpiece location is critical to efficiently plan actions downstream in manufacturing processes. In labor-intensive heavy industries, like construction and shipbuilding, multiple stakeholders interact, stack and move workpieces in the absence of any system to log such actions. While track-by-detection approaches rely on sensing technologies such as Radio Frequency Identification (RFID) and Global Positioning System (GPS), cluttered environments and stacks of workpieces pose several limitations to their adaptation. These challenges limit the usage of such technology to presenting the last known position of a workpiece with no further guidance on a search strategy. In this work we show that a multi-hypothesis tracking approach that models human reasoning can provide a search strategy based on available observations of a workpiece. We show that inventory tracking problems under uncertainty can be approached like probabilistic inference approaches in localization to detect, estimate and update the belief of the workpiece locations. We present a practical Internet-of-Things (IoT) framework for information collection over which we build our reasoning. We also present the ability of our system to accommodate additional constraints to prune search locations. Finally, in our experiments we show that our approach can provide a significant reduction against the conventional search for missing workpieces, of up to 80% in workpieces to visit and 60% in distance traveled. In our experiments we highlight the critical nature of identifying stacking events and inferring locations using reasoning to aid searches even when direct observation of a workpiece is not available.

description: A transition to Kraichnan ultimate regime of convection has been reported in very high Rayleigh numbers experiments, but not in all of them. These apparently contradictory results can be explained by a recent phenomenological model which accounts for the non-ideality of the plate thermal properties [Chillà et al, Physics of Fluids 16:2452 (2004)]. In this paper, we present a direct test of this model, using a low conductivity plate. We found an unaltered transition, not compatible with the model's predictions.

description: Single-use EMG-force models (i.e., a new model is trained each time the electrodes are donned) are used in various areas, including ergonomics assessment, clinical biomechanics, and motor control research. For one degree of freedom (1-DoF) tasks, input-output (black box) models are common. Recently, black box models have expanded to 2-DoF tasks. To facilitate efficient training, we examined parameters of black box model training methods in 2-DoF force-varying, constant-posture tasks consisting of hand open-close combined with one wrist DoF. We found that approximately 40–60 s of training data is best, with progressively higher EMG-force errors occurring for progressively shorter training durations. Surprisingly, 2-DoF models in which the dynamics were universal across all subjects (only channel gain was trained to each subject) generally performed 15–21% better than models in which the complete dynamics were trained to each subject. In summary, lower error EMG-force models can be formed through diligent attention to optimization of these factors.

description: U.S. growers filed an antidumping case against Canadian growers of greenhouse-grown tomatoes, alleging that U.S. growers were being injured, or threatened with material injury, by imports from Canada. The U.S. Department of Commerce determined that imports of greenhouse-grown tomatoes were being sold in U.S. markets at less than fair market value. The U.S. International Trade Commission determined the “like product” to be all fresh market tomatoes, concluding the domestic industry was not materially injured. Anecdotal evidence used by the Commission Department in determining like product ignores the wealth of knowledge that economics can add. An economic model is proposed for purposes of determining like product.

description: Designing strategies and policies that will alleviate poverty and improve household food security and nutritional well being is one of the most important challenges facing government policymakers in developing countries. The choice of strategies and policies depends in large part on understanding the dynamics of poverty, especially the mechanisms by which households acquire and spend income and cope with cries such as poor harvest or loss of employment. This work by Harold Alderman and Marito Gracia represents IFPRI's first comprehensive analysis of the longitudinal data on 800 households collected between 1986 and 1989 in Pakistan. This unique data set enables researchers to examine the temporal dimensions of food security, income and labor dynamics, consumption and saving dynamics, nutrition and health progress, and many other issues that cannot be adequately addressed using cross-sectional data. The report of a wide-ranging series of studies focuses on Pakistan. It is the rural component of a Food Security Management Project jointly undertaken by IFPRI, the government of Pakistan, and the U.S Agency for international Development (USAID) Mission in Pakistan. An IFPRI field office, based at the Ministry of Agriculture in Islamabad since 1986, indicates IFPRI's long-term commitment to this program. This report represents the microanalysis part program, while earlier IFPRI studies, including Effects of Exchange Rate and Trade Policies on Agriculture in Parkistan, Research Report 84, and The Demand for Public Storage of Wheat in Pakistan, Research Report 77, have tackled macroeconomic issues facing food security. Other studies in human capital accumulation, agricultural credit, water management, agricultural production, and nonfarm linkage are under way. The research was carried out in collaboration with the major economic research institutes in Pakistan: the Punjab Economic Research Institute in Labore, the Applied Economic Research Centre of the University Of Peshawar, the Department of Social Welfare at the University of Baluchistan, and the Pakistan Institute of Development Economics in Islambad. The USAID Mission in Pakistan had provided sustained support to this research program.
A Journey from Improper Gaussian Signaling to Asymmetric Signaling

description: The deviation of continuous and discrete complex random variables from the traditional proper and symmetric assumption to a generalized improper and asymmetric characterization (accounting correlation between a random entity and its complex conjugate), respectively, introduces new design freedom and various potential merits. As such, the theory of impropriety has vast applications in medicine, geology, acoustics, optics, image and pattern recognition, computer vision, and other numerous research fields with our main focus on the communication systems. The journey begins from the design of improper Gaussian signaling in the interference-limited communications and leads to a more elaborate and practically feasible asymmetric discrete modulation design. Such asymmetric shaping bridges the gap between theoretically and practically achievable limits with sophisticated transceiver and detection schemes in both coded/uncoded wireless/optical communication systems. Interestingly, introducing asymmetry and adjusting the transmission parameters according to some design criterion render optimal performance without affecting the bandwidth or power requirements of the systems. This dual-flavored article initially presents the tutorial base content covering the interplay of reality/complexity, propriety/impropriety and circularity/noncircularity and then surveys majority of the contributions in this enormous journey.

Evaluation of an educational package for families in British Columbia whose children have been recently diagnosed with epilepsy
Creators: name: Massey, Cathy Lynn
Publisher: name: University of British Columbia
Year: 2009

description: This descriptive study was designed to invite parents to evaluate the usefulness of the Epilepsy Education Package they received subsequent to their child's diagnosis of epilepsy. The Evaluating Printed Education Materials (EPEM) Model (Bernier, 1993) was used to guide the development of the educational resource package. An evaluation tool was created by adapting the Client Satisfaction Questionnaire (CSQ) developed by Daniel Larsen et al(1979). The population of interest was families from the inpatient neurosciences unit and outpatient neurology clinic at British Columbia's Children's Hospital which is a part of Children and Women's Health Center of British Columbia as well as from the Epilepsy Society of British Columbia who received the Educational Resource Package when their child was newly diagnosed with epilepsy. Evaluation tools were sent to 93 families through a mailed out evaluation tool containing 39 questions in which 13 utilize a Likert scale, 15 closed-ended questions, and 11 open-ended questions as well as a demographic tool containing 10 questions. Telephone follow-up and interviews were done with 48 of these families. Analysis of the data was done descriptively. The percentages for each Likert-scaled response and closed-ended question were calculated. The open-ended questions and telephone data were analyzed using content analysis. Patterns or common themes were identified and responses categorized into these themes. The study's findings indicate that most parents read and found the educational resource package helpful. Recommendations were given as to how the package could be improved. The recommendations included adding extra suggestions for resources and supports for families, such as: information for siblings, websites, and an annotated bibliography or reference list for extra reading. Implications for clinical practice and education as well as research is included.

description: We report extensive differential V-band photometry and high-resolution spectroscopy for the 1.14 day, detached, double-lined eclipsing binary BT Vul (F0+F7). Our radial-velocity monitoring and light curve analysis lead to absolute masses and radii of M1 = 1.5439 +/- 0.0098 MSun and R1 = 1.536 +/- 0.018 RSun for the primary, and M2 = 1.2196 +/- 0.0080 MSun and R2 = 1.151 +/- 0.029 RSun for the secondary. The effective temperatures are 7270 +/- 150 K and 6260 +/- 180 K, respectively. Both stars are rapid rotators, and the orbit is circular. A comparison with stellar evolution models from the MIST series shows excellent agreement with these determinations, for a composition of [Fe/H] = +0.08 and an age of 350 Myr. The two components of BT Vul are very near the zero-age main sequence.

description: A spatial equilibrium model is used to quantify the effects of a severance tax on the Pennsylvania coal market. Two regions are identified: the Pennsylvania Market Area and an import/export region. The impacts on prices and quantities of coal supplied and demanded are found to be small. Little of the tax is exported from Pennsylvania, with a high proportion of the tax being passed back to Pennsylvania coal producers. Although the tax revenue exceeds the welfare losses in Pennsylvania, this result is very sensitive to the magnitude of the Pennsylvania own-price demand elasticity.
