description: We summarise results on the infrared behaviour of Landau gauge QCD from the Green's functions approach and lattice calculations. Approximate, nonperturbative solutions for the ghost, gluon and quark propagators as well as first results for the quark-gluon vertex from a coupled set of Dyson-Schwinger equations are compared to quenched and unquenched lattice results. Almost quantitative agreement is found for all three propagators. Similar effects of unquenching are found in both approaches. The dynamically generated quark masses are close to `phenomenological' values. First results for the quark-gluon vertex indicate a complex tensor structure of the non-perturbative quark-gluon interaction.

description: Apprehension of risk induces certain behaviour into a farmer and this would grossly affect enterprise selection and consequently his resource use and allocation pattern. In this study, risk preferences of food crop farmers in Osun State were measured and efficient resource use and allocation patterns were modeled and suggested. Data from 165 farmers, obtained using a two-stage sampling procedure were used in the study. Analytical tools were descriptive statistics, Risk Behavioural Model (RBM) and Target Minimization of Total Absolute Deviation (T-MOTAD). Risk averse farmers were 144 representing 87.3 percent while the risk preferers were 21 representing 12.7 percent. However risk preference was higher among the males, farmers with larger farm sizes and smaller household sizes. Efficient utilization of labour and borrowed capital was discovered among the risk preferers than the risk averters; hence a significant difference existed in their returns (P< 0.01). It is recommended that farm management research and the extension packages should be channel to the farmers while considering the socio-economic environments that characterize their risk preferences.
Powerful gravitational-wave bursts from supernova neutrino oscillations

description: During supernova core collapse and bounce resonant active-to-active, as well as active-to-sterile, neutrino ($ν$) oscillations can take place. Over this phase weak magnetism increases antineutrino mean free paths, and thus its luminosity. Because oscillations feed mass-energy into the target $ν$ species, the large mass-squared difference between $ν$ states implies a huge amount of power to be given off as gravitational waves (GWs) due to the universal {\it spin-rotation} and the spin-magnetic coupling driven $ν$ anisotropic flow, which is coherent over the oscillation length. The spacetime strain produced is about two orders of magnitude larger than those from $ν$ difussion or neutron star matter anisotropies. GWs observatories as LIGO, VIRGO, GEO-600, TAMA-300, etc., can search for these bursts far out to the VIRGO cluster of galaxies.

description: Based on the data from the recent Nigerian National Living Standard Survey (NLSS), income, demographic and environmental factors as well as exposure to western culture influence the consumption of dairy products in the country. From the results of the descriptive and quantitative analyses, it is safe to infer that demand will grow and therefore government will need to design polices to promote the production and marketing of dairy products to enhance supply in the local market on a sustainable basis.

In particular, we show how the position of the stellar locus in color-color diagrams can be used to estimate the accuracy of photometric zeropoint calibration to better than 0.01 mag in 0.03 deg2 patches. Using this method, we estimate that typical photometric zeropoint calibration errors for SDSS imaging data are not larger than ~0.01 mag in the g, r, and i bands, 0.02 mag in the z band, and 0.03 mag in the u band (root-mean-scatter for zeropoint offsets).

description: This paper reviews theories, current conditions, and barriers to liquidization and concentration of farmland in Japan and discusses perspectives on further research. We make special effort in introducing theoretical approach to understand institutional barriers to farmland liquidization, such as the farmland law system, compensation for tenants' investment, farmland transaction costs, and the high potential for farmland conversion. Since many of the studies in Japan on this topic are anecdotal or based on case studies, econometric studies from overseas that use detailed data are selectively reviewed for reference. Future studies should consider linkage and complementarities between anecdotal or case studies and quantitative approaches. Quantitative studies that test various hypotheses in debate are required. Use of farm or region level panel data should be useful and effective to take into consideration for identification of causality. Rigorous policy evaluations are also necessary for assessing and improving policies that promote structural adjustment.
Information and communication technology (ICT) literacy in teacher education : a case study of the University of British Columbia
Creators: name: Guo, Ruth Xiaoqing
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this research was to increase an understanding of the practices and issues of information and communications technology (ICT) literacy in the teacher education program at the University of British Columbia, Canada. I explored characteristics related to (ICT) literacy: A) program effects on ICT competencies; B) gender and ICT literacy; C) age and ICT literacy; D) attitudes toward technology and ICT literacy; and E) program effects on ICT use. Mixed methods were applied to analyse quantitative data and interpret interviews and observations in the program. The data were collected from large-scale pre- and post-program surveys of student teachers in the 2001-2002 and 2003-2004 years. A research team in the Faculty of Education at U.B.C. administered questionnaires to the teacher education students in September 2001 (n = 877) and 2003 (n=828) at the beginning of the academic year and post-program instruments were completed in May and June 2002 and 2004. Data included interviews with student teachers, observations of student teachers in courses, and videotapes of student teachers’ microteaching sessions for evidence of pedagogical integration. Findings from both quantitative analyses of this study suggest that the perception that both female and male students have of their ICT competencies significantly increased between the start and end of the program. Male students had significantly higher means than females at the start of their program. An increase of the female students was significantly higher than the increase of the males at the end of the program, but was not enough to offset the difference. Teacher candidates’ attitudes toward technology also changed significantly by the end of the program. Findings from this study revealed that the teacher candidates’ attitudes toward ICT and their ICT competencies were highly correlated. ICT competencies varied with attitudes. ICT competencies increase or decrease with changes of attitudes. No significant effects were found for a digital divide by age in this study. There were strong correlations between the students’ perceptions of their ICT competencies and their ICT uses in schools. Results from this study inform the pedagogy of integrating technology into curriculum and instruction and suggest further research on effective uses of ICT in teacher education.

description: Planetary-scale waves are thought to play a role in powering the yet-unexplained atmospheric superrotation of Venus. Puzzlingly, while Kelvin, Rossby and stationary waves manifest at the upper clouds (65--70 km), no planetary-scale waves or stationary patterns have been reported in the intervening level of the lower clouds (48--55 km), although the latter are probably Lee waves. Using observations by the Akatsuki orbiter and ground-based telescopes, we show that the lower clouds follow a regular cycle punctuated between 30$^{\circ}$N--40$^{\circ}$S by a sharp discontinuity or disruption with potential implications to Venus's general circulation and thermal structure. This disruption exhibits a westward rotation period of $\sim$4.9 days faster than winds at this level ($\sim$6-day period), alters clouds' properties and aerosols, and remains coherent during weeks. Past observations reveal its recurrent nature since at least 1983, and numerical simulations show that a nonlinear Kelvin wave reproduces many of its properties.

description: In this work, we report measurements of the height profile of transverse dunes in the coastal dune field known as ``Lençóis Maranhenses'', northeastern Brazil. Our measurements show that transverse dunes with approximately the same height present a variable brink position relative to the crest, in contrast to the case of barchan dunes. Based on our field data, we present a relation for the dune spacing as a function of the crest-brink distances of transverse dunes. Furthermore, we compare the measurements with simulations of transverse dunes obtained from a two-dimensional dune model, where a phenomenological definition is introduced for the length of the separation streamlines on the lee side of closely spaced transverse dunes. We find that our model reproduces transverse dune fields with similar inter-dune distances and dune aspect ratios as measured in the field.

description: The purpose of this paper is to provide firms in the food and agricultural sector a model that enables them to assess their corporate social initiatives in conjunction with their stakeholders. Building on the concepts of corporate social responsibility (CSR), corporate social performance (CSP) and the relational view the paper argues that firms can improve the results of their corporate social initiatives by setting up a dialogue with their stakeholders and to relate this to their internal organizational delivery system. The CSP model is based on the SERVQUAL methodology. The model addresses how a potential (mis)match between a firm’s CSR initiative and stakeholders expectations and experiences is related to four gaps in the firm’s internal organizational delivery system and how this effects the firm’s CSP. CSP measurement is a fundamental part of a firm’s strategy if one accepts the tenet that firm survival and growth depends on the ability of firms to meet the needs of their stakeholders and to manage corporate image. It is to the firm to make stakeholder’s expectations transparent and plan action in alignment with the firm’s business strategy. The paper contributes to a more comprehensive understanding of CSP measurement by linking a firm’s CSP to the firm’s delivery system. It addresses how CSP can evolve over time by putting the dialogue with stakeholders central.
Enhanced Time-Frequency Representation and Mode Decomposition

Subjects: subject: Signal Processing (eess.SP)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Time-frequency representation (TFR) allowing for mode reconstruction plays a significant role in interpreting and analyzing the nonstationary signal constituted of various modes. However, it is difficult for most previous methods to handle signal modes with closely-spaced or spectrally-overlapped instantaneous frequencies (IFs) especially in adverse environments. To address this issue, we propose an enhanced TFR and mode decomposition (ETFR-MD) method, which is particularly adapted to represent and decompose multi-mode signals with close or crossing IFs under low signal-to-noise ratio (SNR) conditions. The emphasis of the proposed ETFR-MD is placed on accurate IF and instantaneous amplitude (IA) extraction of each signal mode based on short-time Fourier transform (STFT). First, we design an initial IF estimation method specifically for the cases involving crossing IFs. Further, a low-complexity mode enhancement scheme is proposed so that enhanced IFs better fit underlying IF laws. Finally, the IA extraction from signal's STFT coefficients combined with the enhanced IFs enables us to reconstruct each signal mode. In addition, we derive mathematical expressions that reveal optimal window lengths and separation interference of our method. The proposed ETFR-MD is compatible with previous related methods, thus can be regarded as a step toward a more general time-frequency representation and decomposition method. Experimental results confirm the superior performance of the ETFR-MD when compared to a state-of-the-art benchmark.

description: Due to manifold scandals meat production and processing has been in the spotlight of public concern over the last decades. CSR can safeguard an enterprise against risks following e.g. food safety, environmental or social incidences in a sector. To reap the full benefit of their CSR involvement it is essential for firms to communicate their activities to their stakeholders in a credible way. Given this background, the objective of the paper is to find answers to the following questions: To what extent pursue and communicate German meat companies CSR activities, what factors determine their CSR involvement and communication and regarding the latter, how do those companies evaluate a CSR standardization? The results of our study are based on a standardized survey of 68 North Rhine-Westphalian companies in the pork value chain. The data is analysed using descriptive as well as uni- and multivariate methods. The findings show that companies of the pork sector already are active in the area of CSR. They also communicate their activities, however, not yet to a great extent. The level and kind of CSR performance and CSR communication vary between companies depending on firm characteristics (e.g. size). Main motives for firms to engage in CSR are differentiation from competitors and consideration of stakeholders’ requirements. In addition the analysis provides some indication that doing good has not to be at the expense of doing well. A CSR standard that could inform stakeholders in a credible way about companies’ CSR activities is evaluated very heterogeneously. The complementary implementation of voluntary more demanding and quasi-obligatory minimum CSR standards could be a solution to this problem.

description: For the calculation of the partition function $\mathcal{Z}$ of small, isolated and interacting many body systems an improvement with respect to previous formulations is presented. By including anharmonicities and employing a variational approach quantum effects can be treated even at very low temperatures. In order to test its accuracy the novel approach is applied to the exactly solvable Lipkin-Meshkov-Glick model (LMGM). For thermodynamic properties and level densities good agreement with the exact calculations is found.

description: It has recently been shown that the maximal kinematical invariance group of polytropic fluids, for smooth subsonic flows, is the semidirect product of SL(2,R) and the static Galilei group G. This result purports to offer a theoretical explanation for an intriguing similarity, that was recently observed, between a supernova explosion and a plasma implosion. In this paper we extend this result to discuss the symmetries of discontinuous flows, which further validates the explanation by taking into account shock waves, which are the driving force behind both the explosion and implosion. This is accomplished by constructing a new set of Rankine-Hugoniot conditions, which follow from Noether's conservation laws. The new set is dual to the standard Rankine-Hugoniot conditions and is related to them through the SL(2,R) transformations. The entropy condition, that the shock needs to satisfy for physical reasons, is also seen to remain invariant under the transformations.

A Lie pseudoalgebra is a generalization of the notion of a Lie conformal algebra for which C[\partial] is replaced by the universal enveloping algebra H of a finite-dimensional Lie algebra [BDK]. The finite (i.e., finitely generated over H) simple Lie pseudoalgebras were classified in [BDK]. In a series of papers, starting with the present one, we classify all irreducible finite modules over finite simple Lie pseudoalgebras.

The measured fluxes confirm that the Sgr A* infrared spectrum is dominated by the synchrotron emission of nonthermal electrons. The infrared counterpart exhibits no significant short term variability but demonstrates flux variations on daily and yearly scales. The observed emission arises away from the position of the dynamical center of the S2 orbit and would then not originate from the closest regions of the black hole.

description: The duration of a gamma-ray burst (GRB) is a key indicator of its physics origin, with long bursts perhaps associated with the collapse of massive stars and short bursts with mergers of neutron stars.However, there is substantial overlap in the properties of both short and long GRBs and neither duration nor any other parameter so far considered completely separates the two groups. Here we unambiguously classify every GRB using a machine-learning, dimensionality-reduction algorithm, t-distributed stochastic neighborhood embedding (t-SNE), providing a catalog separating all Swift GRBs into two groups. Although the classification takes place only using prompt emission light curves,every burst with an associated supernova is found in the longer group and bursts with kilonovae in the short, suggesting along with the duration distributions that these two groups are truly long and short GRBs. Two bursts with a clear absence of a supernova belong to the longer class, indicating that these might have been direct-collapse black holes, a proposed phenomenon that may occur in the deaths of more massive stars.

description: We address the problem of collective motion across a barrier like encountered in fission. A formula for the quantal decay rate is derived which bases on a recently developed variational approach for functional integrals. This formula can be applied to low temperatures that have not been accessible within the former PSPA type approach. To account for damping of collective motion one particle Green functions are dressed with appropriate self-energies.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Neutron Star Crustal Interface Waves

description: The eigenfrequencies of nonradial oscillations are a powerful probe of a star's interior structure. This is especially true when there exist discontinuities such as at the neutron star (NS) ocean/crust boundary, as first noted by McDermott, Van Horn & Hansen. The interface mode associated with this boundary has subsequently been neglected in studies of stellar nonradial oscillations. We revisit this mode, investigating its properties both analytically and numerically for a simple NS envelope model. We find that it acts like a shallow surface ocean wave, but with a large radial displacement at the ocean/crust boundary due to flexing of the crust with shear modulus $μ\ll P$, the pressure. This displacement lowers the mode's frequency by a factor of $\sim(μ/P)^{1/2}\sim0.1$ in comparison to a shallow surface wave frequency on a hard surface. The interface mode may be excited on accreting or bursting NSs and future work on nonradial oscillations should consider this mode. Our work also implies an additional mode on massive and/or cold white dwarfs with crystalline cores, which may have a frequency between the f-mode and g-modes, an otherwise empty part of the frequency domain.

description: Long-lived dark states, in which an experimentally accessible qubit is not in thermal equilibrium with a surrounding spin bath, are pervasive in solid-state systems. We explain the ubiquity of dark states in a large class of inhomogenous central spin models using the proximity to integrable lines with exact dark eigenstates. At numerically accessible sizes, dark states persist as eigenstates at large deviations from integrability, and the qubit retains memory of its initial polarization at long times. Although the eigenstates of the system are chaotic, exhibiting exponential sensitivity to small perturbations, they do not satisfy the eigenstate thermalization hypothesis. Rather, we predict long relaxation times that increase exponentially with system size. We propose that this intermediate chaotic but non-ergodic regime characterizes mesoscopic quantum dot and diamond defect systems, as we see no numerical tendency towards conventional thermalization with a finite relaxation time.

Behind the Buckskin Curtain : aboriginal youth participation in spiritual ceremonies combined with drama activities
Creators: name: Machelle, Beverley Anne
Publisher: name: University of British Columbia
Year: 2011

description: Behind the Buckskin Curtain looks at how spiritual ceremonies and drama activities impact Aboriginal youth's healing experience? This thesis is about an Aboriginal youth study that was conducted from April 9 - May 14, 2003. The study included youth between the ages of 19 - 25 who were living in Vancouver, British Columbia. Participants committed to get together once a week for six weeks at the Native Education Centre in the inner-city of Vancouver BC. This study was proposed to inquire into the spiritual needs of Aboriginal Youth in British Columbia. Specifically this study inquires into the participants regained healing through their use of spiritual ceremonies and drama activities. Chapters one to three discuss healing in the British Columbia Aboriginal community. Chapter four discusses the way in which the Aboriginal youth study unfolded. Chapter five and six look at the results and the conclusions, implications, and recommendations the study indicates. Aboriginal youth share with us what they have learned prior to the study about their spiritual lives and about how they have learned through their experience with spiritual ceremonies combined with drama activities. The results show that Aboriginal youth did gain healing through their participation in spiritual ceremonies combined with drama activities.

description: Der Grünten ein Solitärberg in der Gemeinde Rettenberg und freistehender Vorankündiger der Oberstdorfer Alpenkette hat in der Region des Oberallgäus eine wichtige Schlüsselfunktion als Kurzerholungsgebiet und „Sportund Freizeitberg“ sowohl für die direkt umliegenden Dörfer aber auch für Einzugsgebiete bis Augsburg, Stuttgart und Lindau am Bodensee. Speziell durch seine übersichtliche Maßstäblichkeit bietet er jungen Familien aber auch Sportvereinen und Senioren eine hervorragende Anlaufstelle, ein bisschen „frische Luft zu schnappen“. Vor allem durch die aktuelle Schließung und die geplante Veräußerung der Ski-Liftanlagen ist diese wichtige Funktion des Berges akut gefährdet und drastische Einschnitte in die Regionalkultur sind als Folge zu befürchten.Die vorliegende Arbeit beginnt im Maßstab der Regionalplanung, indem zunächst für die gesamte Grüntenregion ein neues Nutzungskonzept erarbeitet wird. Als Herzstück dieses Konzeptes kristallisiert sich die neue Gipfelstation heraus, die hier sowohl konzeptionell einen Vorschlag an die Gemeinde richtet, in der aktuellen Situation eine neue Haltung zu finden, als dann auch konstruktiv ausgearbeitet wird, wie dort ein attraktiver Publikumsmagnet für die Region entstehen kann.
description: The „Grünten“ a solid mount in the municipality of Rettenberg and “welcomer” for the great Alps beginning in Oberstdorf has a key function not only for the surrounding villages but also cities like Augsburg, Stuttgart and Lindau (Bodensee) regarding sports and outdoor activities. It is an essential area for people not looking for “higher, faster, bigger” but searching a familiar scale for spending their spare time there. Currently the closing and planned selling of the existing ski-lifts are endangering not only nature and wildlife but also cultural aspects as potential investors always dream of making the big money but don t care about the people living there or the beauty itself the Grünten offers.This is a conceptional work including the whole region around the Grünten, working out an idea how the need of sports and outdoor activities we humans have can be combined with respecting and even protecting our nature s values. There is the idea of a new lift-building holding the key function for the whole area. A new and special concept regarding the use and functions of that building ensemble has been worked out as well as a interesting wood-construction wanting to attract future visitors and invite them to the peak of that beautiful and still familiar mountain.
Preconditioning nonlocal multi-phase flow

Subjects: subject: Numerical Analysis (math.NA)

description: We propose an efficient solver for saddle point problems arising from finite element approximations of nonlocal multi-phase Allen--Cahn variational inequalities. The solver is seen to behave mesh independently and to have only a very mild dependence on the number of phase field variables. In addition we prove convergence, in three GMRES iterations, of the approximation of the two phase problem, regardless of mesh size or interfacial width. Numerical results are presented that illustrate the competitiveness of this approach.
The helium abundances in HgMn and normal stars

description: The parameter-free model of diffusion in the atmospheres of HgMn stars (Michaud 1986; Michaud et al 1979) predicts that helium should sink below the He II ionization zone in order that diffusion of other elements may take place, and that all HgMn stars should have deficits of helium in their photospheres, with a minimum deficit of 0.3 dex. In this study, the Smith & Dworetsky (1993) sample of HgMn stars and normal comparison stars is examined, and the helium abundances determined by spectrum synthesis using echelle spectra taken at Lick Observatory and the AAT. The prediction is confirmed; all HgMn stars are deficient in He by as much as 1.5 dex. Also, two HgMn stars, HR7361 and HR7664, show clear evidence of helium stratification.

description: Hyperspectral image (HSI) classification is one of the most active research topics and has achieved promising results boosted by the recent development of deep learning. However, most state-of-the-art approaches tend to perform poorly when the training and testing images are on different domains, e.g., source domain and target domain, respectively, due to the spectral variability caused by different acquisition conditions. Transfer learning-based methods address this problem by pre-training in the source domain and fine-tuning on the target domain. Nonetheless, a considerable amount of data on the target domain has to be labeled and non-negligible computational resources are required to retrain the whole network. In this paper, we propose a new transfer learning scheme to bridge the gap between the source and target domains by projecting the HSI data from the source and target domains into a shared abundance space based on their own physical characteristics. In this way, the domain discrepancy would be largely reduced such that the model trained on the source domain could be applied on the target domain without extra efforts for data labeling or network retraining. The proposed method is referred to as physically-constrained transfer learning through shared abundance space (PCTL-SAS). Extensive experimental results demonstrate the superiority of the proposed method as compared to the state-of-the-art. The success of this endeavor would largely facilitate the deployment of HSI classification for real-world sensing scenarios.
