description: We present the first ex post study that quantitatively analyses the effects of a licence buyback and enhanced quota trading on the profitability and productivity of individual vessels in a fishery. Using firm-level data and a profit index decomposition method, we find that small and large vessels and three different trawler fleets all experienced substantial productivity gains in the year immediately following a licence buy-back and the establishment of a quota brokerage service. The apparent ongoing benefits of the buy-back and increased quota trading over the sample period are in stark contrast to the generally unfavourable long-term outcomes commonly associated with vessel buy-backs in input-controlled fisheries.

description: Imaginary-time time-dependent Density functional theory (it-TDDFT) has been proposed as an alternative method for obtaining the ground state within density functional theory (DFT) which avoids some of the difficulties with convergence encountered by the self-consistent-field (SCF) iterative method. It-TDDFT was previously applied to clusters of atoms where it was demonstrated to converge in select cases where SCF had difficulty with convergence. In the present work we implement it-TDDFT propagation for {\it periodic systems} by modifying the Quantum ESPRESSO package, which uses a plane-wave basis with multiple $\boldsymbol{k}$ points, and has the options of non-collinear and DFT+U calculations using ultra-soft or norm-conserving pseudo potentials. We demonstrate that our implementation of it-TDDFT propagation with multiple $\boldsymbol{k}$ points is correct for DFT+U non-collinear calculations and for DFT+U calculations with ultra-soft pseudo potentials. Our implementation of it-TDDFT propagation converges to the exact SCF energy (up to the decimal guaranteed by double precision) in all but one case where it converged to a slightly lower value than SCF, suggesting a useful alternative for systems where SCF has difficulty to reach the Kohn-Sham ground state. In addition, we demonstrate that rapid convergence can be achieved if we use adaptive-size imaginary-time-steps for different kinetic-energy plane-waves.

SiO masers in TX Cam: Simultaneous VLBA observations of two 43 GHz masers at four epochs

description: We present the results of simultaneous high resolution observations of v=1 and v=2, J=1-0 SiO masers toward TX Cam at four epochs covering a stellar cycle. Near maser maximum (Epochs III and IV), the individual components of both masers are distributed in ring-like structures but the ring is severely disrupted near stellar maser minimum (Epochs I and II). In Epochs III and IV there is a large overlap between the radii at which the two maser transitions occur. However in both epochs the average radius of the v=2 maser ring is smaller than for the v=1 maser ring, the difference being larger for Epoch IV. The observed relative ring radii in the two transitions, and the trends on the ring thickness, are close to those predicted by the model of Humphreys et al. (\cite{humphreys02}). In many individual features there is an almost exact overlap in space and velocity of emission from the two transitions, arguing against pure radiative pumping. At both Epochs III and IV in many spectral features only 50% of the flux density is recovered in our images, implying significant smooth maser structure. For both transitions we find that red- and blue-shifted masers occur in all parts of the rings, with relatively few masers at the systemic velocity. Thus there is no evidence for rotation, although the blue-shifted masers are somewhat more prominent to the west. At all four epochs red-shifted components are generally brighter than blue-shifted ones. At Epochs III and IV, we see many filamentary or spoke-like features in both v=1 and v=2 masers, especially in the red-shifted gas. These spokes show systematic velocity gradients consistent with a decelerating outward flow with increasing radius. We outline a possible model to explain why, given the presence of these spokes, there is a deficit of maser features at the systemic velocity.

description: In this paper we analyse the optimal management of a renewable resource (groundwater) with stock-dependent extraction cost and a backstop substitute, facing two-sector linear demands. Application to the Kiti region in Cyprus demonstrates the model’s performance and is used to test for the difference between optimal and myopic behaviour. It is found that the presence of a backstop resource diminishes the importance of optimal dynamic behaviour, whereas in the absence of backstop the optimal control solution yields a value for social welfare significantly larger than the myopic policy.

description: The accuracy in position and flux density of 19 large radio continuum source catalogues has been determined using SPECFIND, a new tool recently made available through the CDS. The ~67000 radio continuum spectra with three or more frequencies produced by SPECFIND were used to cross-correlate sources from different catalogues and to calculate offsets in right ascension and declination in the various catalogues with respect to the positions given in the NRAO VLA Sky Survey (NVSS) catalogue, which was adopted as a reference. The flux densities reported in the catalogues were compared to those predicted by the composite spectra, enabling us to assess the quality of the flux density calibration of the different catalogues.

description: We present measurements of the real diagonal microwave conductivity of the reentrant insulating quantum Hall phases in the first excited Landau level at temperatures below 50 mK. A resonance is detected around filling factor $ν=2.58$ and weaker frequency dependence is seen at $ν=2.42$ and 2.28. These measurements are consistent with the formation of a bubble phase crystal centered around these $ν$ at very low temperatures.

description: We study a spin-1 single flavor color superconducting phase which results from a color-spin locking (CSL) interaction in two-flavor quark matter. This phase is particularly interesting for compact star cooling applications since the CSL phase may survive under charge neutrality constraints implying a mismatch between up- and down-quark chemical potentials which can destroy the scalar diquark condensate. CSL gaps are evaluated within an NJL model and they are found to be consistent with cooling phenomenology if a density dependent coupling constant is used.

Subjects: Job Satisfaction, Faculty Members, King Faisal University, Saudi Arabia

description: The study aimed at identifying the level of job satisfaction among faculty members at King Faisal University in the Kingdom of Saudi Arabia, and to reveal differences in the responses of faculty members about their level of job satisfaction according to study variables: gender, nationality, college, academic rank, and experience. The descriptive approach was adopted by building a questionnaire consisting of (36) items, divided into five areas: job, social relations at work, salaries and incentive, direct administration, professional development, and promotions. The study tool was applied to (252) faculty members from various scientific and humanitarian colleges. The findings showed that the level of job satisfaction among faculty members at King Faisal University was high. The field of social relations at work came at a very high level, while the field of salaries and incentives came at a moderate level. It was also found that there were no statistically significant differences (α = 0.05) attributed to the variables: college, academic rank, nationality, and the number of years of experience. While the differences were due to the gender variable and in favor of males.

description: In the neighborhood of Sgr A*, several stars (S2, S12, S14, S1, S8, S13) enjoy an accurate determination of their orbital parameters. General Relativity predicts that the central black hole acts as a gravitational lens on these stars, generating a secondary image and two infinite series of relativistic images. For each of these six stars, we calculate the light curves for the secondary and the first two relativistic images, in the Schwarzschild black hole hypothesis, throughout their orbital periods. The curves are peaked around the periapse epoch, but two subpeaks may arise in nearly edge-on orbits, when the source is behind or in front of Sgr A*. We show that for most of these stars the secondary image should be observable during its brightness peak. In particular, S14 is the best candidate, since its secondary image reaches K=23.3 with an angular separation of 0.125 mas from the apparent horizon of the central black hole. The detection of such images by future instruments could represent the first observation of gravitational lensing beyond the weak field approximation.

description: We propose and demonstrate a method for the construction of highly uniform, multilayered, orientation-controlled superstructures of CdSe/CdZnS core/shell colloidal nanoplatelets (NPLs) using bi-phase liquid interface. These atomically-flat nanocrystals are sequentially deposited, all face-down onto a solid substrate, into slabs having monolayer-precise thickness and excellent homogeneity over several tens of cm2 areas. Owing to the near-unity surface coverage and film uniformity of this deposition technique, amplified spontaneous emission (ASE) is observed from an uncharacteristically thin colloidal film having only 6 layers of NPLs, which corresponds to a mere 42 nm thickness. Furthermore, systematic studies of optical gain properties of these NPL superstructures constructed having precise numbers of NPL layers tuned from 6 to 15 revealed the reduction in the gain threshold with the increasing number of NPL monolayers, along with a continuous spectral shift in the position of the ASE peak (by ~18 nm). These observations can be well explained by the variation of the optical field confinement factor with the NPL waveguide thickness and propagation wavelength. This work demonstrates the possibility of fabricating thickness-tunable, large-area three-dimensional superstructures made of NPL building blocks, which can be additively constructed one monolayer at a time. The proposed technique can also be extended to build hybrid NPL films of mixed orientations and allow for precise large-area device engineering.

description: The Australian National Water Initiative (NWI) builds on the foundations of earlier water reforms, attempts to correct earlier errors in both policy and its implementation, and seeks to better define some of the policy aims with the benefit of hindsight. However, despite the deliberate effort to improve on earlier reforms, the NWI still embodies a significant economic paradox. Although policymakers have shown their faith in the market insofar as allocating water between competing agricultural interests is concerned, they have not shown the same degree of faith in the ability of urban users to respond to price signals. This paper attempts to shed at least some light on this question by examining the responses of a number of State governments across Australia to the NWI. The paper specifically explores the rationale for non-price regulation in the urban context but challenges the long-term viability of this approach.

description: The flavor changing neutral current (FCNC) transitions t --> q'H and t --> q'V_i (V_i=γ, g, Z) are studied in the context of the effective Lagrangian approach. We focus on the scenario in which these decays are predominantly induced by new physics effects arising from the Yukawa sector extended with dimension-six SU_L(2) X U_Y(1)-invariant operators, which generate the most general CP-even and CP-odd tq'H vertex at the tree level. For the unknown coefficients, we assume a slightly modified version of the Cheng-Sher ansatz. We found that the branching ratio for the Higgs-mediated FCNC t--> q'V_i decays are enhanced by two or three orders of magnitude with respect to the results expected in models with extended Higgs sectors, such as the general two-Higgs doublet model. We discuss the possibilities of detecting this class of decays at the LHC.

description: In New Zealand, it is increasingly recognised, including by government, that water resource allocation and water quality are issues of national importance. Agriculture is frequently portrayed by public media as a major user of water and a major contributor to worsening water quality. We outline the water management systems in New Zealand, and the use of water by agriculture. Official reports on agriculture’s impact on New Zealand water availability and quality are summarised. We report how the New Zealand public perceive water, its management, and the roles of agriculture in water issues. Data from a nationwide mail survey were analysed to determine how New Zealanders assess the state of New Zealand lakes, rivers and streams, and aquifers, the performance of three agencies responsible for management of freshwater resources, and willingness to fund stream enhancement. We provide brief explanations for the failures of water resource management in New Zealand and report on options, including community-based responses that might address some of the mounting public, scientific, and government concerns about trends in water quantity and quality. A willingness to pay proposition, concerning riparian areas, included in the nationwide survey provides some evidence that the public are willing to pay for improved waterway management. Relevant non-market valuation studies also indicate that the public places considerable value on preservation values of water in New Zealand.

Numerical simulations show the suitability of the proposed COVID-19 model for the outbreak that occurred in Wuhan, China.

description: This paper uses suburb-level quarterly data to model residential water demand in Brisbane, Australia, from 1998 to 2003. In this system, residential consumption is charged using a fixed annual service fee with no water entitlement followed by a fixed volumetric charge per kilolitre. Water demand is specified as average quarterly household water consumption and the demand characteristics include the marginal price of water, household income and size, and the number of rainy and warm days. The findings not only confirm residential water as price and income inelastic, but also that the price and income elasticity of demand in owner-occupied households is higher than in rented households. The results also show that weather, particularly summer months and the number of rainy days, exerts a strong influence on residential water consumption.
An exploration of first nations artists in Alert Bay, BC : connecting to the art market from home
Creators: name: Neufeld, Margaret Rachel McKellin
Publisher: name: University of British Columbia
Year: 2009

description: Historically, Northwest Coast First Nations artists have been active participants in local and external trade from their communities. Today, many Northwest Coast First Nations artists work in large art centers, such as art galleries in Victoria and the Lower Mainland, and/or in their local communities. In Alert Bay, B.C., home of the 'Namgis People from the Kwakwaka'wakw Nation, artists continue to create economic ties to art centers within and beyond their local community. The objective of this study is to a) explore why some First Nations artists choose to be based in Alert Bay while participating in the art market, b) identify the mechanisms that are used by artists to develop and maintain connections to both local and non-local art market centers and, c) analyze the kinds of issues or consequences that arise as a result of being involved in these types of transactions. In conducting fieldwork over a period of one month, participant-observation and semi-structured interviews with First Nations artists living in Alert Bay, I have found that artists place importance upon belonging to an aboriginal community that influences how they develop and that they maintain economic ties within and beyond their community. I intend to show that artists seek recognition for their economic contributions as artists from community members at home while they simultaneously seek recognition for their sociocultural participation by members of the non-native art-world. By analyzing the narratives of artists, tensions over the "authenticity" of the artist, the quality and standard of their work and their perceived recognition in the community arise as they attempt to participate and gain recognition in both local and non-local economic arenas.

The yield of device resistances below 100 $kΩ$, at 300 $K$, is around 50%. We measure at 2 $K$ a hysteretic magneto-resistance due to the magnetization reversal of the ferromagnetic leads. The relative difference between the resistance in the antiparallel (AP) orientation and the parallel (P) orientation is about 2%.

description: A key feature of water policy reform in Australia has been the separation of water access entitlements from land titles and the establishment of markets for water. However, the separation of water entitlements from land failed to account for a number of characteristics that were implicit in the joint right. This has given rise to a number of third-party effects as water is traded in an incomplete market. This paper describes four third-party effects of water trade; reliability of supply, timeliness of delivery, storage and delivery charges, and water quality and examines policy responses to address these effects. The discussion draws on the concepts of exclusiveness and rivalry to determine the applicability of property rights and other solutions to the third-party effects of trade. It is likely that many of the third-party effects of trade discussed in this paper do not warrant policy intervention at the national or state level, but intervention at the local level may be warranted. The costs of addressing some third-party effects may outweigh the benefits. Where there are significant gains from trade, the existence of these third-party effects should not been seen as a reason to impede trade.

description: The partial ionization of the solar plasma causes several nonideal effects such as the ambipolar diffusion, the Hall effect, and the Biermann battery effect. Here we report on the first three-dimensional realistic simulations of solar local dynamo where all three effects were taken into account. The simulations started with a snapshot of already saturated battery-seeded dynamo, where two new series were developed: one with solely ambipolar diffusion and another one also taking into account the Hall term in the generalized Ohm's law. The simulations were then run for about 4 hours of solar time to reach the stationary regime and improve the statistics. In parallel, a purely MHD dynamo simulation was also run for the same amount of time. The simulations are compared in a statistical way. The results show that, with the inclusion of the ambipolar diffusion, the amplitudes of the incompressible perturbations related to Alfven waves are reduced, and the Poynting flux is absorbed, with a frequency dependence. The Hall effect causes the opposite action: significant excess of incompressible perturbations is generated and an excess of the Poynting flux is observed in the chromospheric layers. The model with ambipolar diffusion shows, on average, sharper current sheets and slightly more abundant fast magneto-acoustic shocks in the chromosphere. The model with the Hall effect has higher temperatures at the lower chromosphere and stronger and more vertical magnetic field concentrations all over the chromosphere. The study of high-frequency waves reveals that significant power of incompressible perturbations is associated with areas with intense and more vertical magnetic fields and larger temperatures. We find a positive correlation between the magnitude of the ambipolar heating and the temperature increase at the same location after a characteristic time of 10^2 sec.

description: The relative merits of different systems of property rights to allocate water among different extractive uses are evaluated for the case where variability of supply is important. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water entitlements defined as shares of the total quantity available. In the second, there are two types of water entitlements, one for water with a high security of supply and the other a lower security right for the residual supply. The third is a system of entitlements specified as state-contingent claims. With zero transaction costs, all systems are efficient. In the realistic situation where transaction costs matter, the system based on state-contingent claims is globally optimal, and the system with high-security and lower security entitlements is preferable to the system with share entitlements.

description: We calculate the density of states of a two dimensional electron gas located at the interface of a GaAlAs/GaAs heterojunction. The disorder potential which is generally created by a single doping layer behind a spacer, is here enhanced by the presence of a second delta doped layer of scatterers which can be repulsive or attractive impurities. We have calculated the density of states by means of the Klauder's approximation, in the presence of a magnetic field of arbitrary strength. At low field either band tails or impurity bands are observed for attractive potentials, depending on the impurity concentration. At higher field, impurity bands are observed for both repulsive and attractive potentials. We discuss the effect of such an asymmetrical density of states on the transport properties in the quantum Hall effect regime.

description: Management of the Murray–Darling river system involves a large number of users with imprecisely defined rights, and an aggregate rate of resource use that is environmentally unsustainable. One possible policy response is to make formal or informal contracts with users, under which users receive current benefits in return for a commitment to forgo usage rights in future. In this paper, this issue is explored with specific reference to the possibility of repurchasing the renewal rights for irrigation licenses.
Les programmes d’écolabellisation face aux motivations égoïstes ou altruistes des consommateurs et à la nature publique ou privée des attributs environnementaux

description: La réussite des écolabels tient dans la combinaison des deux principaux facteurs que constituent, d’un côté, les interactions entre la nature privée ou publique des attributs environnementaux (c’est-à-dire le type de bénéfices individuels ou collectifs qu’ils procurent) et, de l’autre, la part des consommateurs ayant une attitude sociale égoïste ou altruiste. Ce second facteur permet notamment de comprendre pourquoi certains écolabels appliqués au même type de produits et ayant un niveau fixe d’attributs privés et publics, fonctionnent de manière différente selon les pays. On montre ainsi que, si le degré d’altruisme de certains consommateurs est élevé, le comportement d’achat de ces consommateurs altruistes peut empêcher les consommateurs plus « égoïstes » d’accéder au bien écolabellisé et, de ce fait, réduire le bénéfice environnemental global recherché. Il apparaît en outre important d’éviter une politique uniforme en mettant en place des stratégies de marketing adaptées à différents segments de consommateurs.

description: A generalization of the Bogoliubov transformation is developed to describe a space compactified fermionic field. The method is the fermionic counterpart of the formalism introduced earlier for bosons (J. C. da Silva, A. Matos Neto, F. C. Khanna and A. E. Santana, Phys. Rev. A 66 (2002) 052101), and is based on the thermofield dynamics approach. We analyse the energy-momentum tensor for the Casimir effect of a free massless fermion field in a $d$-dimensional box at finite temperature. As a particular case the Casimir energy and pressure for the field confined in a 3-dimensional parallelepiped box are calculated. It is found that the attractive or repulsive nature of the Casimir pressure on opposite faces changes depending on the relative magnitude of the edges. We also determine the temperature at which the Casimir pressure in a cubic boc changes sign and estimate its value when the edge of the cybe is of the order of confining lengths for baryons.

description: Une part importante de la population française déclare lors d’enquêtes d’opinion ne pas boire l’eau du robinet, bien que la qualité de l’eau distribuée par ce canal fasse l’objet de contrôles sanitaires rigoureux et que le prix de l’eau en bouteille soit environ cent fois plus élevé que le prix de l’eau du robinet. On cherche alors à identifier les facteurs qui incitent les ménages à choisir l’eau du robinet comme eau de boisson. Sur un échantillon de ménages répartis sur la France entière, on montre que, outre les caractéristiques sociodémographiques (niveau de revenu, niveau d’éducation, type d’habitat), la qualité de l’environnement immédiat du ménage, mesurée ici par la qualité des eaux brutes, influence également sa décision de boire l’eau du robinet.
The XMM-Newton view of the relativistic spectral features in AXJ0447-0627

description: The XMM-Newton observation of the optically Type 1 AGN AXJ0447-0627 (z=0.214) unambiguously reveals a complex, bright and prominent set of lines in the 4-8 keV rest frame energy range. Although, from a phenomenological point of view, the observed properties can be described by a simple power law model plus 5 narrow Gaussian lines (at rest frame energies of nearly 4.49, 5.55, 6.39, 7.02 and 7.85 keV), we find that a model comprising a power law (Gamma of the order of 2.2), a reflected relativistic continuum, a narrow Fe I Kalpha line from neutral material as well as a broad Fe Kalpha relativistic line from a ionized accretion disk represents a good physical description of the data. The ''double horned'' profile of the relativistic line implies an inclination of the accretion disk of the order of 45 degree, and an origin in a narrow region of the disk, from R_in of the order of 19 GM/c^2 to R_out of the order of 30 GM/c^2. The narrow Fe I Kalpha line from neutral material is probably produced far from the central black hole, most likely in the putative molecular torus. Although some of these properties have been already found in other Type 1 AGN and discussed in the literature, at odd with the objects reported so far we measure high equivalent widths (EWs) of the observed lines: nearly 1.4 keV for the ``double horned'' relativistic line and nearly 0.4 keV for the narrow line.

description: Le développement durable est aujourd’hui un objectif explicite de toutes les politiques. Il vise à concilier enjeux économiques, environnementaux et sociaux, dans un souci d’équité intergénérationnelle. L’approche par la « viabilité » cherche à prendre en compte un ensemble d’enjeux de durabilité dans un cadre multicritère et dynamique. Cette démarche, complémentaire des approches classiques basées sur l’optimisation d’un seul critère (par exemple, économique), permet de définir les configurations d’exploitation durable d’un système écologique et économique et d’explorer les décisions susceptibles d’éviter ou de sortir d’une crise de surexploitation. On illustre ici cette approche à l’aide de résultats obtenus dans le cas de la gestion des pêches.

description: Core-periphery structure, the arrangement of a network into a dense core and sparse periphery, is a versatile descriptor of various social, biological, and technological networks. In practice, different core-periphery algorithms are often applied interchangeably, despite the fact that they can yield inconsistent descriptions of core-periphery structure. For example, two of the most widely used algorithms, the k-cores decomposition and the classic two-block model of Borgatti and Everett, extract fundamentally different structures: the latter partitions a network into a binary hub-and-spoke layout, while the former divides it into a layered hierarchy. We introduce a core-periphery typology to clarify these differences, along with Bayesian stochastic block modeling techniques to classify networks in accordance with this typology. Empirically, we find a rich diversity of core-periphery structure among networks. Through a detailed case study, we demonstrate the importance of acknowledging this diversity and situating networks within the core-periphery typology when conducting domain-specific analyses.

description: Recent discussions of the origins of the thermodynamical asymmetry ("the arrow of time") by Huw Price and others are critically assessed. This serves as a motivation for consideration of relationship between thermodynamical and cosmological causes. Although the project of clarification of the thermodynamical explanandum is certainly welcome, Price excludes another interesting option, at least as viable as the sort of Acausal-Particular approach he favors, and arguably more in the spirit of Boltzmann himself. Thus, the competition of explanatory projects includes three horses, not two. In addition, it is the Acausal-Particular approach that could benefit enormously from dissociation from fanciful ideas of low-entropy future boundary conditions entertained by Price. Novel revolutionary developments in observational cosmology, as well as in the nascent astrophysical discipline of physical eschatology, have obliterated such hypotheses. Also, the Acausal-Anthropic approach we propose, offers another clear instance of disteleological nature of the anthropic principle.
