description: Recently, many works focus on the implementation of collective communication operations adapted to wide area computational systems, like computational Grids or global-computing. Due to the inherently heterogeneity of such environments, most works separate "clusters" in different hierarchy levels. to better model the communication. However, in our opinion, such works do not give enough attention to the delimitation of such clusters, as they normally use the locality or the IP subnet from the machines to delimit a cluster without verifying the "homogeneity" of such clusters. In this paper, we describe a strategy to gather network information from different local-area networks and to construct "logical homogeneous clusters", better suited to the performance modelling.

description: By 2020, Dutch dairy chains envisage to be self-sufficient with regard to energy used by dairy farms and dairy processors. This would require dairy farms to produce 25 PJ per year, possibly by a combination of wind, solar and biogas. Current analyses focus on biogas. To evaluate the project’s feasibility we estimated the expected technical and financial performance of 4 types of business models, i.e. “CHP-farm”, “CHP-large”, “green gas” and “central upgrading”. Data stem among others from 23 biogas plants in the Netherlands. Anticipating that CHP-models and green gas models occur with a likelihood of 40% and 60% respectively, the total number of biogas plants at dairy farms would amount to 463. There would however be an expected deficit of Euro 157 million over the project’s life time, i.e. Euro 0.02 per liter of milk. Fully switching to green gas is expected to reduce the number of plants to 438 with an aggregated financial surplus, i.e. of Euro 368 million. Findings are useful in current stakeholder debates on dairy chains’ sustainability, and, more specifically, level of subsidies, availability of co-digestion materials and market opportunities of digestate.

description: The exhaustion of natural resources is a central problem in the international agenda. The particular case of Amazon forest is at the top on the international environmental discussion. Two related problems are keys to be considered in the discussion of sustainable development in this region. First the predatory use of the natural resources of the forest mainly timber and genetic resources. Second the recognition of the existence of a population of around 20 million inhabitants in the region defined as “Legal Amazon Area”, aiming the improvement on the living conditions, enhancement of income level and acceleration of development. How to match both objectives is a puzzle faced by the present generation. The region is populated by initiatives of international non-governmental-organizations, most of them carrying good intentions but lacking the necessary knowledge on local formal and informal institutions to find ways to reach sustainable development. The result is the accelerated process of natural resources depletion, and social disorganization. The case of the production of Brazilian Nuts stands as a corollary of the lack of an institutional structure of property rights that does not provide incentives for sustainable development. The opposite effect is being observed as a result of the fragility of observable institutional arrangements. The case provides the counterfactual for the analysis of Ostrom (1990,2008), where she presents virtuous cases of sustainable exploration of natural resources, mostly based on informal but solid institutions.

description: In der Geschlechterforschung wird angeregt über den Zusammenhang von Feminismus, Neoliberalismus, demografischer Wende in der Familienpolitik und der sich verändernden Rolle von Müttern debattiert. Dieser Beitrag zielt darauf ab, die Art und das Ausmaß der Rezeption öffentlicher Diskurse um Vereinbarkeit herauszuarbeiten. Hiernach werden insbesondere hochqualifizierte Frauen durch wirkmächtige Leitbilder darauf verpflichtet, Karriere und Mutterschaft selbstständig zu vereinbaren, während die Kritik am asymmetrischen Geschlechterverhältnis weitgehend verstummt. In diesem Beitrag wird auf der empirischen Basis qualitativer Interviews analysiert, ob und wie sich der ‚kritische‘ oder ‚neoliberale‘ Vereinbarkeitsdiskurs in der Alltagskommunikation und in Vereinbarkeitsstrategien berufstätiger Mütter niederschlägt. Als zentrales Ergebnis ist festzustellen, dass diese sich weitgehend als ‚Familienmanagerinnen‘ sehen, die durch gute Planung, Struktur und Organisation Vereinbarkeit selbst herstellen. Der neoliberale mediale Vereinbarkeitsdiskurs wurde von ihnen damit weitestgehend übernommen und in Vereinbarkeitsstrategien umgesetzt, die durch individuelle Lösungen gekennzeichnet sind.

description: The somatic marker hypothesis (SMH) has been one of the most influential theories in the neurosciences since the early 1990s, when it was formulated by Antonio Damasio in his book Descartes’ Error (1994). Since then, various studies, for and against, have been written without a verdict. Firstly, this study provides a comprehensive explanation of the SMH. Secondly, it provides a detailed assessment of the relevance of the amygdala in the process of making unconscious decisions. In contrast, we cite some results that suggest that the ventromedial prefrontal cortex would be involved in our rational decisions. Finally, we review some of the criticism of the SMH that was based on the mixed results obtained in the Iowa Gambling Task. We suggest that the main value of the SMH is that it resolves the brain-body duality problem. However, the hypothesis by itself is insufficient to claim that the decision-making process is mainly based on our feelings. Although the decision-making process uses unconscious somatosensory responses, it is a more complex physical-emotional-rational process, which still lacks sufficient evidence to be located

description: Markets for agricultural and food products are characterized by high information asymmetries since producers, processors and retailers are in most cases much better informed about the quality of their products than consumers (Henson/Traill 1993). Often consumers are only at (prohibitively) high costs or not at all able to control important quality criterions such as food safety, nutritional value or region of origin. Such credence attributes can result in market failure due to a lack of credible information in the market (Akerlof 1970). As a result, attempts to protect consumers against food hazards, product adulteration and deception have gained much relevance in food supply chains (Deimel et al. 2008). Besides the more or less voluntary private certification schemes that have been established, large parts of the agrifood sector are already mandatorily regulated, especially in Europe. Therefore, in recent years, food law has been undergoing major changes in the European Union (EU) (Theuvsen/Hollmann-Hespos 2007; Haertel: 2007). General Food Law Regulation (EC) 178/2002 and the so-called EU hygiene package (Regulations (EC) 852/2004, 853/2004 and 854/2004) have strongly contributed to a much more intensive regulation of food production. The farm to fork approach laid down in Regulation (EC) 178/2002 has resulted in the obligation to secure “traceability of food […] at all stages of production, processing and distribution” (Art. 18).

Stochastic Acceleration in Relativistic Parallel Shocks

Year: 2004

description: (abridged) We present results of test-particle simulations on both the first and the second order Fermi acceleration at relativistic parallel shock waves. We consider two scenarios for particle injection: (i) particles injected at the shock front, then accelerated at the shock by the first order mechanism and subsequently by the stochastic process in the downstream region; and (ii) particles injected uniformly throughout the downstream region to the stochastic process. We show that regardless of the injection scenario, depending on the magnetic field strength, plasma composition, and the employed turbulence model, the stochastic mechanism can have considerable effects on the particle spectrum on temporal and spatial scales too short to be resolved in extragalactic jets. Stochastic acceleration is shown to be able to produce spectra that are significantly flatter than the limiting case of particle energy spectral index -1 of the first order mechanism. Our study also reveals a possibility of re-acceleration of the stochastically accelerated spectrum at the shock, as particles at high energies become more and more mobile as their mean free path increases with energy. Our findings suggest that the role of the second order mechanism in the turbulent downstream of a relativistic shock with respect to the first order mechanism at the shock front has been underestimated in the past, and that the second order mechanism may have significant effects on the form of the particle spectra and its evolution.

description: This article is a philosophical elucidation about the concept of nature in relation to man. The question is not idle: is there something such as nature, or is it only a way of stringing together everything that is not man-made? Given that the ethical, political and instrumental dimension that will be adopted depends on the way in which this concept is constructed. The concept of life is also analyzed. It is concluded that the solutions for biosphere sustainability must be radical and that there is no need to depend on the ghost of our disappearance as a species to make definitive and long-term decisions.

description: This work aims at identifying and quantifying uncertainties related to elastic and viscoelastic parameters, which characterize the arterial wall behavior, in one-dimensional modeling of the human arterial hemodynamics. The chosen uncertain parameters are modeled as random Gaussian-distributed variables, making stochastic the system of governing equations. The proposed methodology is initially validated on a model equation, presenting a thorough convergence study which confirms the spectral accuracy of the stochastic collocation method and the second-order accuracy of the IMEX finite volume scheme chosen to solve the mathematical model. Then, univariate and multivariate uncertain quantification analyses are applied to the a-FSI blood flow model, concerning baseline and patient-specific single-artery test cases. A different sensitivity is depicted when comparing the variability of flow rate and velocity waveforms to the variability of pressure and area, the latter ones resulting much more sensitive to the parametric uncertainties underlying the mechanical characterization of vessel walls. Simulations performed considering both the simple elastic and the more realistic viscoelastic constitutive law show that the great uncertainty of the viscosity parameter plays a major role in the prediction of pressure waveforms, enlarging the confidence interval of this variable. In-vivo recorded patient-specific pressure data falls within the confidence interval of the output obtained with the proposed methodology and expectations of the computed pressures are comparable to the recorded waveforms.

description: Interaktionen zwischen männlichen Geflüchteten und alteingesessenen Frauen werden seit den sexuellen Übergriffen in der Silvesternacht 2015 in Köln als problematisch gefasst. Hier wird ein Zugang zur geschlechterübergreifenden Interaktion gewählt, der von positiven Alltagskontakten ausgeht, nämlich der Interaktion zwischen Geflüchteten und ehrenamtlich für sie Engagierten. Leitfadengestützte Interviews mit 26 ehrenamtlich Engagierten werden in Anlehnung an die Grounded Theory analysiert. Die aus dieser Analyse heraus entwickelte Kernkategorie „Separierung der Geschlechter“ verweist vor allem auf herkunftskulturelle Zuschreibungen und/oder Sozialisation, aber auch auf weiblich dominierte Unterstützungsnetzwerke und auf geschlechtertrennende Angebote für Geflüchtete. Diese Separierung der Geschlechter führt zu Unsicherheiten bei geschlechterübergreifenden Interaktionen, insbesondere beim Umgang mit Nähe und Distanz. Das Ansetzen von kultureller Differenz wird in der Literatur skeptisch betrachtet. Kritisiert werden ein homogenisierender, statischer und deterministischer Kulturbegriff sowie die Reproduktion und Verstärkung von Vorurteilen und Stereotypen. Dennoch, in der Rekonstruktion von Interaktionen durch die befragten Engagierten spielt kulturelle Differenz eine entscheidende Rolle.

description: Recent works try to optimise collective communication in grid systems focusing mostly on the optimisation of communications among different clusters. We believe that intra-cluster collective communications should also be optimised, as a way to improve the overall efficiency and to allow the construction of multi-level collective operations. Indeed, inside homogeneous clusters, a simple optimisation approach rely on the comparison from different implementation strategies, through their communication models. In this paper we evaluate this approach, comparing different implementation strategies with their predicted performances. As a result, we are able to choose the communication strategy that better adapts to each network environment.

description: Based on the measured sizes of broad line region of the reverberation-mapping AGN sample, two new empirical relations are introduced to estimate the central black hole masses of radio-loud high-redshift ($z > 0.5$) AGNs. First, using the archival $IUE/HST$ spectroscopy data at UV band for the reverberation-mapping objects, we obtained two new empirical relations between the BLR size and \Mg/\C emission line luminosity. Secondly, using the newly determined black hole masses of the reverberation-mapping sample for calibration, two new relationships for determination of black hole mass with the full width of half maximum and the luminosity of \Mg/\C line are also found. We then apply the relations to estimate the black hole masses of AGNs in Large Bright Quasar Surveyq and a sample of radio-loud quasars. For the objects with small radio-loudness, the black hole mass estimated using the $R_{\rm BLR} - L_{\eMg/\eC}$ relation is consistent with that from the $R_{BLR} - L_{3000Å/1350 Å}$ relation. But for radio-loud AGNs, the mass estimated from the $R_{BLR} - L_{\eMg/\eC}$ relation is systematically lower than that from the continuum luminosity $L_{3000Å/1350Å}$. Because jets could have significant contributions to the UV/optical continuum luminosity of radio-loud AGNs, we emphasized again that for radio-loud AGNs, the emission line luminosity may be a better tracer of the ionizing luminosity than the continuum luminosity, so that the relations between the BLR size and UV emission line luminosity should be used to estimate the black hole masses of high redshift radio-loud AGNs.

description: Using ammonium based nitrogen fertilizers in crop production has been shown to acidify soils. Lime used to correct soil pH is an important cost to producers. Recommendations of the optimal level of nitrogen to apply typically ignore the cost of lime created by nitrogen fertilization. This study was aimed to estimate soil pH change in response to nitrogen and lime application, and determine the effect of considering the cost of lime on recommendations about the optimal level of nitrogen. Yield response and pH functions were estimated and used to determine optimal levels of inputs. The effect of the cost of lime on recommendations about the optimal level of nitrogen was found to be marginal. Nitrogen acidification was found to be more severe with nitrogen application amounts above recommended rates than with nitrogen that is used by the plant.
Responses of ground beetle (Coleoptera: carabidae_ species and assemblages to forest practices in the interior Douglas-fir forests of British Columbia

description: The Opax Mountain Silvicultural Systems Project was initiated in 1993 to address concerns over the widespread use of uniform stand-level partial cutting in the dry Douglas-fir forests of BC's Southern Interior. Various alternative harvesting methods were tested, and responses of several wildlife indicator groups were measured. The following study examined responses of ground beetle (Coleoptera: Carabidae) species and assemblages using a variety of diversity indices. The alternative harvesting practices were: 1) 20% and 2) 50% removal using individual-tree selection (I.T.S.); 3) 20% and 4) 50% removal using patch-cuts of 0.1, 0.4, and 1.6 ha; 5) 35% removal using 50% I.T.S. on 70% of the treatment area, leaving 30% in reserves; and 6) uncut controls. Results showed that species richness, evenness, and heterogeneity were greater in logged treatments. However, only in the heterogeneity values of Mud Lake assemblages (1996/1997) was there a general increase in diversity that accompanied either an increase in percent forest removal, or a change from control to I.T.S. to patch-cut methods of harvest. Other than taxonomic distinctness, no other distinctness index decreased in logged treatments, and none of the distinctness indices displayed any trend in decreasing with an increasing percentage of forest removal, or to a change from control to I.T.S. to patch-cut methods of harvest. In multivariate analysis, carabid assemblages within each site (Mud Lake and Opax Mountain.) showed patch-cut treatments to cluster/map together and I.T.S. treatments to cluster/map together. Dominance structure tables generally showed that carabid assemblages from lower percent removal treatments, as well as from I.T.S. methods, to most resemble dominance structure found in control blocks. Species analysis showed that carabid species respond to logging in a variety of ways. Because every method of harvest evidently benefited some species at the expense of others, no one treatment appears sufficient for the whole carabid community. Instead, a mix of harvesting methods that maintained the greatest number of all native forest species, including sensitive species, and over an indefinite period of time, would be the best strategy for the preservation of carabid biodiversity.

description: We develop a general framework for designing conservative numerical methods based on summation by parts operators and split forms in space, combined with relaxation Runge-Kutta methods in time. We apply this framework to create new classes of fully-discrete conservative methods for several nonlinear dispersive wave equations: Benjamin-Bona-Mahony (BBM), Fornberg-Whitham, Camassa-Holm, Degasperis-Procesi, Holm-Hone, and the BBM-BBM system. These full discretizations conserve all linear invariants and one nonlinear invariant for each system. The spatial semidiscretizations include finite difference, spectral collocation, and both discontinuous and continuous finite element methods. The time discretization is essentially explicit, using relaxation Runge-Kutta methods. We implement some specific schemes from among the derived classes, and demonstrate their favorable properties through numerical tests.

description: Entrepreneurship means making discrete changes in livelihood activities that involve substantial risks to income. While the rewards may be substantial, transactions costs may make decisions irreversible. This paper draws a comparison between entrepreneurship and technology adoption. Adopting a new production technology also involves substantial risks. The economics of technology adoption is a well developed literature with many accepted and testable models. Most prominent are the theories of learning by using and learning by doing. We review the technology adoption literature, drawing out lessons for entrepreneurship research. We then apply an entrepreneurship as technology adoption model to a unique dataset collected during the tobacco buyout. The uncertainty in household income and changes in economic environment during the tobacco transition payment program lead many individuals into entrepreneurial activities.

description: Structural studies on Dy-substituted La-2125 type superconductors have been carried out by neutron diffraction experiments at room temperature using a monochromatic neutron beam of wavelength lambda = 1.249 Angstroms. A series of samples with La2-xDyxCa2xBa2Cu4+2xOz stoichiometric composition, for x = 0.1 - 0.5, have been studied for their structural properties. A tetragonal Y-123 unit cell was taken as the starting model for the Rietveld analysis. All the samples fit into the starting model, exhibiting no structural transition taking place with increasing dopant concentration. The results of Rietveld analysis and structural properties are discussed in detail.

description: This paper identifies an internal inconsistency in the Heckscher-Ohlin (H-O) models of international exchange. The inconsistency stems from assuming homogeneity of inputs within a population. This assumption annihilates individual comparative advantage, benefits from exchange and, consequently, existence of autarky prices. In order to remove this inconsistency, I build a two-good multi-individual model by using the microeconomic concept of individual comparative advantage stemming from differences in endowments of qualitatively heterogeneous inputs. The model shows how differences in the distribution of individual production possibilities result in individual specialization, exchange and differences in autarky prices between hypothetically isolated economies. Next, the effect of preference heterogeneity, learning by doing and supply restrictions is examined. In addition to bringing internal logical consistency into the theory of cross-border exchange by demonstrating how price differences between hypothetically isolated economies can be derived from the general neoclassical and Austrian subjectivist principles, this paper addresses the criticisms raised by the labour value theorists. The model can be refined to include comparative advantage in the production of capital goods and differences in the distribution of ownership over natural resources and capital goods. This theoretical approach to inter-local exchange has important policy implications. While the H-O framework lends itself well to conflicting interventionist policies of production allocation based on different interpretations of ambiguous aggregate data, the alternative microeconomic approach acknowledges the importance of the institutional setting in which individual comparative advantage, unknown to an external observer, is discovered, enhanced, and expressed.

description: We review the properties of electron shuttles, i.e. nanoelectromechanical devices that transport electrons one-by-one by utilizing a combination of electronic and mechanical degrees of freedom. We focus on the extreme quantum limit, where the mechanical motion is quantized. We introduce the main theoretical tools needed for the analysis, e.g. generalized master equations and Wigner functions, and we outline the methods how the resulting large numerical problems can be handled. Illustrative results are given for current, noise, and full counting statistics for a number of model systems. Throughout the review we focus on the physics behind the various approximations, and some simple examples are given to illustrate the theoretical concepts. We also comment on the experimental situation.

description: A class of scattered linearized polynomials covering infinitely many field extensions is exhibited. More precisely, the $q$-polynomial over $\mathbb F_{q^6}$, $q \equiv 1\pmod 4$ described in arXiv:1906.05611, arXiv:1910.02278 is generalized for any even $n\ge6$ to an $\mathbb F_q$-linear automorphism $ψ(x)$ of $\mathbb F_q^n$ of order $n$. Such $ψ(x)$ and some functional powers of it are proved to be scattered. In particular this provides new maximum scattered linear sets of the projective line $\mathrm{PG}(1,q^n)$ for $n=8,10$. The polynomials described in this paper lead to a new infinite family of MRD-codes in $\mathbb F_q^{n\times n}$ with minimum distance $n-1$ for any odd $q$ if $n\equiv0\pmod4$ and any $q\equiv1\pmod4$ if $n\equiv2\pmod4$.

description: This study measures the amount of agricultural research engaged in maintenance research for commodities and non-commodities. The percentage of commodity based maintenance research has risen from roughly 35% in 1986 to 41% in 2008. The percentage of non-commodity based agricultural research is roughly 29%. Additionally, an empirical model is developed to explain maintenance research expenditures. The influences of agricultural research funding, climatic conditions, pest and pathogen control, and agricultural production on maintenance research expenditures are tested in the long and short run. Each category has a statistically significant impact on maintenance research expenditures.

description: Modern spectroscopic experiments in few-electron atoms reached the level of precision at which an accurate description of quantum electrodynamics (QED) effects is mandatory. In many cases, theoretical treatment of QED effects has to be performed without any expansion in the nuclear binding strength parameter $Zα$ (where $Z$ is the nuclear charge number and $α$ is the fine-structure constant). Such calculations involve multiple summations over the whole spectrum of the Dirac equation in the presence of the binding nuclear field, which can be evaluated in terms of the Dirac Green function. In this paper we describe the technique of numerical calculations of QED corrections with the Dirac Green function, developed in numerous investigations during the last two decades.

description: Michel Foucaults Unterscheidung zwischen Normativität und Normalisierung im Sinne je unterschiedlicher Machttechniken ist in neuere Gegenwartsdiagnosen eingeflossen. Ziel des Beitrags ist es, diese Unterscheidung als aus intersektionaler Sicht zutiefst problematisch zu erweisen. Dazu nehme ich in methodischer Hinsicht eine von der Arbeit Judith Butlers geprägte Perspektive auf Normativität und die für sie konstitutiven Ausschlüsse ein. Der Fokus meiner Analyse liegt neben der Foucaultschen Begriffsbildung auf deren Weiterentwicklung durch Jürgen Link und insbesondere durch Gundula Ludwig; in Gestalt von Ludwigs Unterscheidung zwischen Heteronormativität und Heteronormalisierung. Zentrales Ergebnis der Analyse ist, dass die letztere Unterscheidung – wie auch die Foucaultsche Unterscheidung zwischen Normativität und Normalisierung – fälschlicherweise impliziert, Normalisierung sei post-normativ. In meiner Diskussion dieses Befundes schlage ich vor, die von Ludwig entwickelte Unterscheidung durch eine Unterscheidung zwischen Heteronormalisierung und Heteronormation zu ersetzen – wobei diese zwei Machttechniken beide als konstitutiv (hetero-)normativ zu verstehen sind.
Observational tests of the evolution of spheroidal galaxies

description: Granato et al (2004) have elaborated a physically grounded model exploiting the mutual feedback between star-forming spheroidal galaxies and the active nuclei growing in their cores to overcome, in the framework of the hierarchical clustering scenario for galaxy formation, one of the main challenges facing such scenario, the fact that massive spheroidal galaxies appear to have formed much earlier and faster than predicted by previous semi-analytical models. After having assessed the values of the two parameters that control the effect of the complex radiative transfer processes on the time-dependent SEDs we have compared the model predictions with a variety of IR to mm data. Our results support a rather strict continuity between objects where stars formed and evolved massive early-type galaxies, indicating that large spheroidal galaxies formed most of their stars when they were already assembled as single objects. The model is successful in reproducing the observed z distribution of K\le20 galaxies at z>1, in contrast with both the classical monolithic and the semi-analytic models, the ratio of star-forming to passively evolving spheroids and the counts and z distributions of EROs. The model also favourably compares with the ISOCAM 6.7 mu counts, with the corresponding z distribution, and with IRAC counts, which probe primarily the passive evolution phase, and with the submm SCUBA and MAMBO data, probing the active star-formation phase. The observed fraction of 24mu selected sources with no detectable emission in either the 8mu or R band nicely corresponds to the predicted surface density of star-forming spheroids with 8mu fluxes below the detection limit. Predictions for the z distributions of 24mu sources detected by MIPS surveys are pointed out. [Abridged]

description: We show that the third-order difference equations proposed by Hirota, Kimura and Yahagi are generated by a pair of second-order difference equations. In some cases, the pair of the second-order equations are equivalent to the Quispel-Robert-Thomson(QRT) system, but in the other cases, they are irrelevant to the QRT system. We also discuss an ultradiscretization of the equations.
