description: Multinomial logit models were used to explain consumer outlet selection when buying beef, specifically roasts, steaks, ground beef, and other types of beef. Outlets were grouped into supermarkets, butchers, warehouses, supercenters, and others, and the probability of selecting each outlet type over a range of demographic and other variables was tested. The models were estimated from household data, with 198,682 observations used in the estimation. Empirical results showed that the type of beef purchased and the size of the purchase played an importance role in the choice of outlet. Furthermore, the increase in mobility seen when consumers buy larger unit cuts could not be fully explained by price discounting. Implications for the potential growth of each outlet types are discussed.

description: This research examines the relationship between U.S. foreign direct investment (FDI) and exports of processed foods to China and identifies management strategies to enhance U.S. competitiveness. Two-stage least-squares empirical econometric results from a simultaneous equation system indicate that there exists a strong complementary relationship between U.S exports and FDI into China. Therefore, the appropriate managerial strategy to access Chinese processed foods markets is to increase overall business activity, both FDI and exports into China.

description: A cluster analysis procedure was used to develop a market segmentation of U.S. crop and livestock farms with annual sales in excess of $100,000. The segments were developed based on the importance of six factors that producers evaluate when selecting input suppliers. The results indicate that four distinct segments exist: Convenience buyers, Balance buyers, Price buyers, and Performance buyers. Differences in preferences across these segments have important implications for the marketing strategies of agricultural input suppliers.
Multi-spin String Solutions in Magnetic-flux Deformed $AdS_n \times S^m$ Spacetime

description: We perform the dimensional reduction of the spacetime of a stack of N D3-branes by the ``twist'' identification of a circle to obtain a new Melvin background. In the near-horizon limit the background becomes the magnetic-flux deformed $AdS_5 \times S^4$ or $AdS_4 \times S^5$ spacetime. After analyzing the classical closed string solutions with several angular momenta in different directions of the deformed spacetimes we obtain two string solutions. The first solution describes a circular closed string located at a fixed value of deformed $AdS_5$ radius while rotating simultaneously in two planes in deformed $AdS_5$ with equal spins $S$. The second solution describes a string rotating in deformed $S^5$ with two equal angular momenta $J$ in the two rotation planes. We investigate the small fluctuations therein and show that the magnetic fluxes have inclination to improve the stability of these classical string solutions.

description: The fabulous results of convolution neural networks in image-related tasks, attracted attention of text mining, sentiment analysis and other text analysis researchers. It is however difficult to find enough data for feeding such networks, optimize their parameters, and make the right design choices when constructing network architectures. In this paper we present the creation steps of two big datasets of song emotions. We also explore usage of convolution and max-pooling neural layers on song lyrics, product and movie review text datasets. Three variants of a simple and flexible neural network architecture are also compared. Our intention was to spot any important patterns that can serve as guidelines for parameter optimization of similar models. We also wanted to identify architecture design choices which lead to high performing sentiment analysis models. To this end, we conducted a series of experiments with neural architectures of various configurations. Our results indicate that parallel convolutions of filter lengths up to three are usually enough for capturing relevant text features. Also, max-pooling region size should be adapted to the length of text documents for producing the best feature maps. Top results we got are obtained with feature maps of lengths 6 to 18. An improvement on future neural network models for sentiment analysis, could be generating sentiment polarity prediction of documents using aggregation of predictions on smaller excerpt of the entire text.

description: We present the luminosity function (LF) of star clusters in M51 based on HST/ACS observations taken as part of the Hubble Heritage project. The clusters are selected based on their size and with the resulting 5990 clusters we present one of the largest cluster samples of a single galaxy. We find that the LF can be approximated with a double power-law distribution with a break around M_V = -8.9. On the bright side the index of the power-law distribution is steeper (a = 2.75) than on the faint-side (a = 1.93), similar to what was found earlier for the ``Antennae'' galaxies. The location of the bend, however, occurs about 1.6 mag fainter in M51. We confront the observed LF with the model for the evolution of integrated properties of cluster populations of Gieles et al., which predicts that a truncated cluster initial mass function would result in a bend in, and a double power-law behaviour of, the integrated LF. The combination of the large field-of view and the high star cluster formation rate of M51 make it possible to detect such a bend in the LF. Hence, we conclude that there exists a fundamental upper limit to the mass of star clusters in M51. Assuming a power-law cluster initial mass function with exponentional cut-off of the form NdM ~ M^-b * exp(-M/M_C)dM, we find that M_C = 10^5 M_sun. A direct comparison with the LF of the ``Antennae'' suggests that there M_C = 4*10^5 M_sun.

description: Electrodeposition and stripping are fundamental electrochemical processes for metals and have gained importance in rechargeable Li-ion batteries due to lithium metal electrodes. The electrode kinetics associated with lithium metal electrodeposition and stripping is crucial in determining performance at fast discharge and charge which is important for electric vertical take-off and landing (eVTOL) aircraft and electric vehicles (EV). In this work, we show the use of Marcus-Hush-Chidsey (MHC) kinetics to accurately predict the Tafel curve data from the work of Boyle et al. We discuss the differences in predictions of reorganization energies from the Marcus-Hush and the MHC models for lithium metal electrodes in four solvents. The MHC kinetic model is implemented and open-sourced within Cantera. Using the reaction kinetic model in a pseudo-2D battery model with a lithium anode paired with a LiFePO$_4$ cathode, we show the importance of accounting for the MHC kinetics and compare it to the use of Butler-Volmer (BV) and Marcus-Hush kinetic models. We find that significant deviation in the overpotentials associated with reaction kinetics for the two different rate laws for conditions of fast discharge and charge relevant for eVTOL and EV respectively.

description: Oligomers and co-oligomers of carbon oxides (CO & CO2) hold considerable potential as high energy density materials (HEDMs) and are of prospective interest to astrochemists. Here, we theoretically investigate the equilibrium geometries, vibrational frequencies, infrared intensities, Raman activities, and energetics of several C2O3 and C2O4 species. Various DFT functionals were employed (BLYP, B3LYP, PBE, PBE0, ωB97X-D) along with Møller-Plesset methods (MP2, SCS-MP2) using the aug-cc-pVQZ basis set. Further calculations (excluding infrared intensities and Raman activities) were performed using Coupled-Cluster methods (CCSD, CCSD(T), CCSD(2)T) with the cc-pVTZ basis set. We discuss the accuracy and suitability of each method for predicting these properties alongside their capability to handle the multi-reference character of these species (through T1 diagnostic, largest T2 amplitudes, %TAE(T), Aλ). The CCSD(2)T and SCS-MP2 approaches provide modest improvements in accuracy over their CCSD(T) and MP2 counterparts, while from the DFT functionals investigated, B3LYP strikes a balance between accuracy and computational cost. Heats of formation and bond dissociation energies were calculated using composite methods (G3MP2, CCCA-CCL, CCCA-S4). The CO2 dimer of D2h symmetry was found to be the best HEDM candidate since its decomposition (to 2CO2), is highly exothermic (by 260.93 kcal/mol at 298 K), alongside high estimated detonation velocities and pressures.

description: This paper focuses on strategic fuzzy alliances (SFAs) and the role of trust in business-to-business relationships. First, a theoretical model of governance choice involving strategic alliances is developed, integrating the Shapiro, Sheppard, and Cheraskin (1992) taxonomy of trust into a neoinstitutional framework. Second, this model, based on transaction theory, is then used to generate necessary and sufficient conditions for trust-based agreements. The third component of this paper is an empirical model, which tests the above theory. Finally, managerial implications from the results are discussed.

description: We investigate transport of spinless fermions through a single site dot junction of M one-dimensional quantum wires. The semi-infinite wires are described by a tight-binding model. Each wire consists of two parts: the non-interacting leads and a region of finite extent in which the fermions interact via a nearest-neighbor interaction. The functional renormalization group method is used to determine the flow of the linear conductance as a function of a low-energy cutoff for a wide range of parameters. Several fixed points are identified and their stability is analyzed. We determine the scaling exponents governing the low-energy physics close to the fixed points. Some of our results can already be derived using the non-self-consistent Hartree-Fock approximation.

description: The evaluation of trust in economic decision making remains on the periphery of mainstream economic analysis and teaching. Yet business managers use trustworthiness in daily exchanges to create competitive advantages for their firms. An exploratory empirical test of Barney and Hansen's three levels of trust (weak, semistrong, and strong) and Lewicki and Bunker's portfolio of governance mechanisms revealed that strong-form trust exists in day-to-day business relationships along with other governance mechanisms. Identity-based transactions were more prevalent than were weak trust market exchanges in important economic transactions.
Modelling Thermonuclear X-ray Bursts on Accreting Neutron Stars

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: In low-mass X-ray binaries, the accretion of stellar material onto a neutron star can fuel unstable thermonuclear flashes known as Type I X-ray bursts. Simulating these events using computational models can provide valuable information about the nature of the accreting system. One-dimensional (1D) astrophysics codes with large nuclear reaction networks are the current state-of-the-art for simulating X-ray bursts. These codes can track the evolution of isotopes through thousands of nuclear reaction pathways, to predict the released nuclear energy and final composition of the ashes. In this thesis, I make extensive use of KEPLER, a 1D code at the forefront of these efforts. I first present improvements to the setup and analysis of KEPLER burst models. By accounting for nuclear heating in the initial conditions, I shorten the thermal burn-in time, thereby reducing computational expense and producing more consistent burst trains. To model bursts fueled by transient accretion events, I perform the first such simulations with fully time-dependent accretion rates. Building upon previous efforts to model the "Clocked Burster", GS 1826$-$238, I precompute a grid of 3840 simulations and sample the interpolated results using Markov Chain Monte Carlo (MCMC) methods. By comparing the predictions to multi-epoch observations, I obtain posterior probability distributions for the system parameters. I then extend these MCMC methods to the pure-helium burster, 4U 1820$-$30, using a grid of 168 simulations. Finally, I discuss potential improvements for future studies, to further develop the computational modelling of accreting neutron stars.

description: Studies of large-scale structures in the Universe, such as superstructures or cosmic voids, have been widely used to characterize the properties of the cosmic web through statistical analyses. On the other hand, the 2-point correlation function of large-scale tracers such as galaxies or halos provides a reliable statistical measure. However, this function applies to the spatial distribution of point-like objects, and therefore it is not appropriate for extended large structures which strongly depart from spherical symmetry. Here we present an analysis based on the standard correlation function formalism that can be applied to extended objects exhibiting arbitrary shapes. Following this approach, we compute the probability excess $Ξ$ of having spheres sharing parts of cosmic structures with respect to a realization corresponding to a distribution of the same structures in random positions. For this aim, we identify superstructures defined as Future Virialized Structures (FVSs) in semi-anaytic galaxies on the MPDL2 MultiDark simulation. We have also identified cosmic voids to provide a joint study of their relative distribution with respect to the superstructures. Our analysis suggests that $Ξ$ provides useful characterizations of the large scale distribution, as suggested from an analysis of sub-sets of the simulation. Even when superstructure properties may exhibit negligible variations across the sub-sets, $Ξ$ has the sensitivity to statistically distinguish sub-boxes that departs from the mean at larger scales. Thus, our methods can be applied in analysis of future surveys to provide characterizations of large-scale structure suitable to distinguish different theoretical scenarios.

description: Julolidine or TPA donor and tricyanofuran acceptor systems are selected to assess the ‘ground state molecular aspects’ and NLO properties of dyes. Six different functionals with five solvents are used to compute vertical excitations and hyperpolarizabilities. The trends in vertical excitations seen in B3LYP functional are comparable with experimental absorption maxima. Intramolecular charge transfer studies correlated with hyperpolarizabilities. The amplitude of sine-shaped potential decreases with an increase in the conjugation chain and solvent polarity. Perturbation potentials have correlation with BLA, quinoid character, hyperpolarizabilities. Increase or decrease in the HOMO–LUMO also depends on the solvent environment. Hyperpolarizabilities, β0 and γ depend on the solvent polarity and the trends are similar in six different functionals. Standard deviation (SD) is used to benchmark the functional performance. Different DFT descriptors including the relatively new ‘hyperhardness’ are correlated with calculated NLO parameters. Correlations are quantitatively analysed using regression coefficients. DFT studies show that selected dyes can stand as good NLO material.

description: We report a detailed attempt to model the ortho-to-para abundance ratio of c-C3H2 so as to reproduce observed values in the cores of the well-known source TMC-1. According to observations, the ortho-to-para ratios vary, within large uncertainties, from a low of near unity to a high of approximately three depending on the core. We used the osu.2003 network of gas-phase chemical reactions augmented by reactions that specifically consider the formation, depletion, and interconversion of the ortho and para forms of the c-C3H2 and its precursor ion c-C3H3+. We investigated the sensitivity of the calculated ortho-to-para ratio for c-C3H2 to a large number of factors. For the less evolved cores C, CP, and D, we had no difficulty reproducing the observed ortho-to-para ratios of 1-2.

‘Music, maps and mavericks: an investigation into traditional Irish music festivals and cultural tourism in Ireland’

subject: Music

description: This research explores the phenomenon of traditional Irish music festivals (TIMFs) and whether they can be considered catalysts for cultural tourism activities. Music has developed ‘from being an adjunct to tourism’ in the 1960s, ‘to occupying a central role as a motivation for travel’ in Ireland in this millennium (Gibson & Connell 2005, p.7). In doing so, music, and specifically TIMFs, offer a basis to develop tourism experiences with which visitors will engage when they attend festivals. However, despite numerous attempts to establish a music strategy within the Irish tourism offering (Failte Ireland 2014, 2015, 2019), the integration of TIMFs into the cultural tourism framework remains elusive, exhibiting a need for the current study. The research questions ask: What are the stakeholder motivations for creating and engaging with traditional Irish music festivals? How can traditional Irish music festivals become a catalyst for cultural tourism activities?The study draws on music, cultural tourism and Irish studies literature, offering insight into culture, heritage and entertainment as a significant tourism subsector (Deane & Doyle, 1997; Laventhol & Horvath, 1986; McKerrell & Hornabrook, 2018). It places people and motivation at the heart of the tourism process which justifies the focus on motivation alongside cultural tourism. Preliminary observations, interviews with festival organisers and the compilation of a catalogue of TIMFs helped to determine a single ethnographic case study of Scoil Samhraidh Willie Clancy (SSWC) as the appropriate research focus. Analysing SSWC as a site of study contributes to its recognition, articulation and measurement within the interdisciplinary fields of music, cultural tourism and Irish studies. Pivotal findings demonstrate that Traditional Irish Music (TIM) can be considered as a hybrid of cultural and creative tourism and also indicate that music is a cultural heritage asset which is consumed by tourists in the context of TIMFs. Conclusions also emerge from field research that illustrate how TIMFs can become a catalyst for the purposes of cultural tourism activities. This study contributes a catalogue of TIMFs. It also contributes to the aforementioned discourses, adding to the literature in an Irish context

description: A series of derivatives of nitroso-substituted cubane were designed through the substitution of hydrogen atoms by nitroso groups one by one. The heats of formation (HOFs) were calculated to explore the thermal stability. The bond dissociation energies (BDEs) and the bond orders of the trigger bonds were also investigated to explore the molecular stability kinetically. Furthermore, the steric effect was confirmed as the determinant of molecular stability for title molecules. To explore the detonation properties, the detonation pressure (P), the detonation velocity (D), the heat of detonation (Q), and the specific density (ρ) were calculated by using the empirical Kamlet-Jacobs (K-J) equations. To predict the sensitivity, the characteristic drop height (H50) is calculated. Based on our calculations, the octanitrosocubane is found with detonation parameters (D = 9.03 km/s, P = 36.96 GPa) better than that of RDX with enough stability.

description: Convolutional Neural Networks (CNN)-based approaches have shown promising results in pansharpening of satellite images in recent years. However, they still exhibit limitations in producing high-quality pansharpening outputs. To that end, we propose a new self-supervised learning framework, where we treat pansharpening as a colorization problem, which brings an entirely novel perspective and solution to the problem compared to existing methods that base their solution solely on producing a super-resolution version of the multispectral image. Whereas CNN-based methods provide a reduced resolution panchromatic image as input to their model along with reduced resolution multispectral images, hence learn to increase their resolution together, we instead provide the grayscale transformed multispectral image as input, and train our model to learn the colorization of the grayscale input. We further address the fixed downscale ratio assumption during training, which does not generalize well to the full-resolution scenario. We introduce a noise injection into the training by randomly varying the downsampling ratios. Those two critical changes, along with the addition of adversarial training in the proposed PanColorization Generative Adversarial Networks (PanColorGAN) framework, help overcome the spatial detail loss and blur problems that are observed in CNN-based pansharpening. The proposed approach outperforms the previous CNN-based and traditional methods as demonstrated in our experiments.

description: This article attempts to measure the impact of India's limited liberalization on the seed industry and on farmers. Using a unique data set on the structure, research, and sales of private seed firms at two points in time, 1987 and 1995, we provide evidence that liberalization increased the competitiveness of the seed industry, and increased the amount of research by Indian and foreign seed firms. Then, using government district level data and data collected from these firms, we show that private hybrids increased farmers' yields. This suggests that Indian farmers are the true beneficiaries of liberalization and that policies that encourage more competition and more research will provide future benefits to farmers.
Adolescent self-harm in a school-based population : prevalence and correlates
Creators: name: Laye, Aviva M.
Publisher: name: University of British Columbia
Year: 2009

description: A paucity of research exists that has examined self-harming behaviour within the nonclinical adolescent population, despite evidence that it is a significant problem that typically originates during this age period (Ross & Heath, 2002; Simeon & Favazza, 2001; van der Kolk, Perry, & Herman, 1991). The present investigation sought to extend previous research, which has primarily focused on self-harm in clinical populations, by examining self-harm in a general school-based adolescent population. More specifically, the current study was designed to: (a) identify the prevalence of overall self-harm and subtypes; (b) explore the nature and subjective experience of self-harm using adolescents' conceptualizations of the behaviour; (c) elucidate the underlying motivations for self-harming; and, (d) evaluate the relation of psychological adjustment, sociodemographic, and health risk variables to self-harming behaviour. To this end, adolescents (N = 424) in grades 9 and 11 completed self-report questionnaires assessing selfharm, psychological adjustment, social desirability, health behaviours, background information, and suicide history. Results revealed that almost half of the adolescents in the present investigation reported self-harm ideation. Further, 15% of adolescents reported engaging in some form of self-harming behaviour, with more females than males reporting doing so. Types of self-harm reported included: cutting-type behaviours, self-battery (i.e., hitting, biting), pill abuse/misuse, eating disordered behaviour, reckless and suicidal-type behaviour, and bonebreaking/falling/jumping. Significant overlap was noted between suicide and self-harm. Results supported, in part, that self-harm functions as a coping mechanism. For instance, adolescents' descriptions of affect revealed that negative emotions, frequently reported prior to self-harming, were reduced through harming, whereas relief and self-conscious emotions (i.e., shame, guilt) increased following an incident of self-harm. Most frequently nominated motivations for self-harm included: depression, loneliness, feelings of failure, self-dislike, anger, and distraction. These findings suggest that self-harm may function as an effective form of affect regulation in response to negative emotions. Results also revealed that motivations that underlie self-harming behaviour differ by gender. Results indicated that anger discomfort and both internalizing and externalizing dimensions of psychological adjustment were significantly associated with self-harm, as hypothesized. Moreover, these relations occurred across genders and were sustained even when social desirability was controlled. Results from logistic regression analyses indicated that suicidal ideation, risky behaviours, antisocial behaviour, and emotional distress were significant in a predictor model of self-harm. Implications for prevention and intervention efforts and suggestions for future research are discussed.

description: The paper focuses on the starch industry in Vietnam. That industry is mainly composed of small firms that adapted to rapid change over the past decade. There are also large firms and multinationals in the industry. Based on 1998 field survey data, an analysis of microefficiency and transaction costs suggests that small and medium firms can survive and prosper in the industry. A policy strategy that promotes small and medium firms increases rural incomes, important in a country that is still mainly rural and where the income gap between urban and rural areas is growing.

description: Proceratophrys aridus is endemic to the Brazilian Caatinga and was described from specimens from the municipality of Milagres, Ceará, Brazil (Cruz et al. 2012. South Am. J. Herpetol. 7:110–122). Understanding food networks and energy transfer in a community requires knowledge of the food habits of the species (Brito et al. 2012. Herpetol. Notes 5:85–89). Anurans are considered opportunistic predators, their diets reflecting the availability of prey of an appropriate size (Duellman and Trueb 1994. Biology of Amphibians. McGraw-Hill, New York. 670 pp.; Giaretta et al. 1998. Rev. Bras. Biol. 15:385–388). As sit-and-wait predators, species of the genus Proceratoprhys (Giaretta et al. 1998, op. cit.; Brito et al. 2012, op. cit.) need to consume large and mobile prey (Boquimpani-Freitas et al. 2002.J. Herpetol. 36:318–322). Brito et al. (2012, op. cit.) reported the diet of P. criticeps to be composed mainly of insects (Isoptera, Orthoptera, and Coleoptera). The diet of P. boiei included insects (Orthoptera, Coleopeta) and spiders (Araneae) (Giarretta et al. 1998. Rev. Bras. Biol. 15:385–388; Klaion et al. 2011. Anais da Academia Brasileira de Ciências 83:1303–1312; Teixeira e Coutinho 2002. Bol. Mus. Biol. Mello Leitão 14:13–20). Spiders (Araneae) were also found in the diet of P. appendiculata (Boquimpani-Freitas et al. 2002. J. Herpetol. 36:318–322) demonstrating that the Araneae may be an important part of the diet of this genus. Araújo et al. (2007. Copeia 2007:855–865) reported spiders and scorpions (Scorpiones) in the diet of an unidentified species of Proceratoprhys. Here we provide information about the diet of P. aridus. A single female P. aridus (SVL = 45.2 mm) was collected in March 2018 in the municipality of Várzea Alegre (6.86944ºS, 39.385ºW, WGS 84; 297 m elev.), Ceará, within the Caatinga domain in northeastern Brazil (SISBIO license No. 62017-1). After euthanasia, we analyzed the stomach contents of the specimen, and identified two categories of prey: Scorpiones and Araneae. This is the first record of the orders Scorpiones and Araneae in the diet of P. aridus.

description: A new method for solving the Bethe-Salpeter equation is developed. It allows to find the Bethe-Salpeter amplitudes both in Minkowski and in Euclidean spaces and, as a by product, the light-front wave function. The method is valid for any kernel given by irreducible Feynman graphs. Bethe-Salpeter and Light-Front equations for scalar particles with ladder + cross-ladder kernel are solved.

description: We present \textit{Spitzer} full-orbit thermal phase curves of the hot Jupiter Qatar-1b, a planet with the same equilibrium temperature---and intermediate surface gravity and orbital period---as the well-studied planets HD 209458b and WASP-43b. We measure secondary eclipse of $0.21 \pm 0.02 \%$ at $3.6~μ$m and $0.30 \pm 0.02 \%$ at $4.5~μ$m, corresponding to dayside brightness temperatures of $1542^{+32}_{-31}$~K and $1557^{+35}_{-36}$~K, respectively, consistent with a vertically isothermal dayside. The respective nightside brightness temperatures are $1117^{+76}_{-71}$~K and $1167^{+69}_{-74}$~K, in line with a trend that hot Jupiters all have similar nightside temperatures. We infer a Bond albedo of $0.12_{-0.16}^{+0.14}$ and a moderate day-night heat recirculation efficiency, similar to HD 209458b. General circulation models for HD 209458b and WASP-43b predict that their bright-spots should be shifted east of the substellar point by tens of degrees, and these predictions were previously confirmed with \textit{Spitzer} full-orbit phase curve observations. The phase curves of Qatar-1b are likewise expected to exhibit eastward offsets. Instead, the observed phase curves are consistent with no offset: $11^{\circ}\pm 7^{\circ}$ at $3.6~μ$m and $-4^{\circ}\pm 7^{\circ}$ at $4.5~μ$m. The discrepancy in circulation patterns between these three otherwise similar planets points to the importance of secondary parameters like rotation rate and surface gravity, and the presence or absence of clouds, in determining atmospheric conditions on hot Jupiters.

description: In the macroscopic gravity approach to the averaging problem in cosmology, the Einstein field equations on cosmological scales are modified by appropriate gravitational correlation terms. We present exact cosmological solutions to the equations of macroscopic gravity for a spatially homogeneous and isotropic macroscopic space-time and find that the correlation tensor is of the form of a spatial curvature term. We briefly discuss the physical consequences of these results.

Host--parasite models on graphs

description: The behavior of two interacting populations, ``hosts''and ``parasites'', is investigated on Cayley trees and scale-free networks. In the former case analytical and numerical arguments elucidate a phase diagram, whose most interesting feature is the absence of a tri-critical point as a function of the two independent spreading parameters. For scale-free graphs, the parasite population can be described effectively by Susceptible-Infected-Susceptible-type dynamics in a host background. This is shown both by considering the appropriate dynamical equations and by numerical simulations on Barabási-Albert networks with the major implication that in the termodynamic limit the critical parasite spreading parameter vanishes.

description: bw2FDM – Das baden-württembergische Begleit- und Weiterentwicklungsprojekt zu Forschungsdatenmanagement

 Forschungsdaten sind die Grundlage für wissenschaftliches Arbeiten aller Disziplinen und garantieren gleichzeitig deren Nachvollziehbarkeit und Qualität. Der Bedarf an Forschungsdatenmanagement für eine digital arbeitende Wissenschaft ist daher zentral. In zahlreichen regionalen, überregionalen und nationalen Projekten werden aktuell Lösungen für die langfristige Sicherung und nachhaltige Bereitstellung von Forschungsdaten sowie für die Bewusstseinsschärfung für den digitalen Wandel entwickelt. Dabei ist eine zentrale Herausforderung für jedes (neue) Projekt, die verschiedenen Strukturen, Initiativen und Projekte so aufeinander abzustimmen, dass Doppelarbeiten vermieden und Synergien geschaffen werden können.
 Der Vortrag zeigt anhand der baden-württembergischen FDM-Landesinitiative bw2FDM auf, wie Kooperation und Wissenstransfer mit verschiedenen Akteuren auf Landes- und auf überregionaler Ebene gelingen kann: Angeführt werden dabei für die überregionale Ebene der Austausch und die Zusammenarbeit mit einem, den gesamten D-A-CH-Raum überspannenden Redaktionsnetzwerk im Rahmen der Informationsplattform forschungsdaten.info sowie anderen Bundeslandinitiativen. Auf Landesebene findet die Vernetzung mitunter im Arbeitskreis Forschungsdatenmanagement (AK FDM) und in mehreren Arbeitsgruppen der vier baden-württembergischen Science Data Center zu gemeinschaftlichen Querschnittsthemen statt. Durch letztere bestehen wiederum Verbindungen in die entstehenden NFDI-Konsortien und andere fachwissenschaftliche Initiativen.

description: We study gaugino-mediated supersymmetry breaking in a six-dimensional SO(10) orbifold GUT model where quarks and leptons are mixtures of brane and bulk fields. The couplings of bulk matter fields to the supersymmetry breaking brane field have to be suppressed in order to avoid large FCNCs. We derive bounds on the soft supersymmetry breaking parameters and calculate the superparticle mass spectrum. If the gravitino is the LSP, the stau_1 or the snu_tau turns out to be the NLSP, with characteristic signatures at future colliders and in cosmology.

Prosodic modifications in infant-directed speech
Creators: name: Church, Robyn
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the present study was to compare three prosodic features of IDS with ADS using natural conversation. The three prosodic features examined were duration of stressed content words, duration of unstressed syllables, and rate of speech (both spoken and read). The first objective was to determine the proportion of the slower rate of speech of IDS as compared to ADS that was accounted for by the exaggerated final syllable lengthening in IDS. The second objective was to determine if read IDS is slower than spoken IDS. The third objective was to determine if unstressed function word syllables were shorter in duration than unstressed syllables in content words and if the durations of these unstressed syllables were comparable in IDS and ADS. Two mothers participated in the study. Two 45-minute audio recordings were made for each participant; the first recording session the mother was interacting with her preverbal infant and in the second recording session she was conversing with a familiar female friend. The results showed that IDS was not significantly slower than ADS when the exaggeratedly lengthened final syllable was excluded from calculations of speech rate. This suggests that non-phrase-final content words are not lengthened in spontaneous IDS as compared to ADS. Previous studies showing lengthening of non-phrase-final content words in IDS as compared to ADS were done using read speech. In this study, speech was read at a slower rate than spontaneous speech, which suggests lengthening of non-phrase-final content words is perhaps an artefact of speech that is read to young children. Durations of unstressed syllables in content words were significantly longer than unstressed syllables in function words in both ADS and IDS. However, there was considerable variability for both categories of words resulting in a large area of overlap. Apart from the robust finding of exaggerated utterance final syllable lengthening in JDS, these data showed that the other prosodic features examined were not exaggerated in IDS compared to ADS.
A model of radiating black hole in noncommutative geometry

description: The phenomenology of a radiating Schwarzschild black hole is analyzed in a noncommutative spacetime. It is shown that noncommutativity does not depend on the intensity of the curvature. Thus we legitimately introduce noncommutativity in the weak field limit by a coordinate coherent state approach. The new interesting results are the following: i) the existence of a minimal non-zero mass to which black hole can shrink; ii) a finite maximum temperature that the black hole can reach before cooling down to absolute zero; iii) the absence of any curvature singularity. The proposed scenario offers a possible solution to conventional difficulties when describing terminal phase of black hole evaporation.
