The fuzzy value of patent litigation under imprecise information
Creators: name: Agliardi, Elettra
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2009
Subjects: SECS-P/01 Economia politica

description: The vague notion of "probabilistic patents" is formalized through a model which combines real option theory and a fuzzy methodology. The imprecise estimates the patent holder possesses about her future profits, the validity and scope of the patent, the litigation costs, the
court's decision etc. under a regime of imperfect inforcement of property rights are specified modelling uncertainty with fuzzy sets. Such methodology is embedded within a real option approach, where the value of a patent includes the option value of litigation. We study how the value of a patent is affected by the timing and incidence of litigation. The main results are compared
with the empirical findings of previous results.

description: The present paper analyzes the forward linkages of a multinational’s investment in a resort which kicks off tourism activity in a LDC. We show that, under quite natural assumptions, overnight stays are increasing in the number of tourism related, differentiated goods and services supplied in equilibrium. These goods and services, if supplied by the local community, represent forward linkages of FDI in tourism. We investigate the multinational’s incentives to promote, reduce or eliminate these forward linkages and the effectiveness of some policy instruments available to a local government to leverage on the presence of FDI and to stimulate domestic entrepreneurship.
Characterisation of lensing selection effects for LISA massive black hole binary mergers

subject: FOS: Physical sciences

description: We present a method to include lensing selection effects due to the finite horizon of a given detector when studying lensing of gravitational wave (GW) sources. When selection effects are included, the mean of the magnification distribution is shifted from one to higher values for sufficiently high-redshift sources. This introduces an irreducible (multiplicative) bias on the luminosity distance reconstruction, in addition to the typical source of uncertainty in the distance determination. We apply this method to study lensing of GWs emitted by massive black hole binary mergers at high redshift detectable by LISA. We estimate the expected bias induced by selection effects on the luminosity distance reconstruction as function of cosmological redshift, and discuss its implications for cosmological and astrophysical analyses with LISA. We also reconstruct the distribution of lensing magnification as a function of the observed luminosity distance to a source, that is the observable quantity in the absence of an electromagnetic counterpart. Lensing provides the dominant source of errors in distance measurements of high-redshift GW sources. Its full characterisation, including the impact of selection effects, is of paramount importance to correctly determine the astrophysical properties of the underlying source population and to be able to use gravitational wave sources as a new cosmological probe.

description: An overlapping generational model of educational investment in a dual labor markets is presented in which education serves both as a screening device and as investment in human capital. Labor market dualism arises not only via the conventional technology (productivity) differential between a primary and a secondary sector, but also by a higher than a labor market clearing wage in the primary sector, to insure no shirking by the workers (an element shared with the efficiency wage theories). The important determinants of the workers' educational investment decision are the degree of discipline in the labor market and the cost of education. Among the three most commonly discussed educational policies of maximizing the number of the educated, maximizing the primary sector employment and maximizing social welfare, the last one, i.e., the most efficient one, leads to a lower level of education subsidy by the government.

description: This paper focuses on the private and social rates of return to R&D capital in the three vertically linked sectors, primary agriculture, food processing, and farm machinery and equipment. Evidence supporting a divergence between these rates is found for primary agriculture and food processing. Using a cost function approach, the private rates of return to R&D capital ranged from an average of 10.2% per annum for food processing to 22.3% for farm machinery and equipment. In the case of agriculture, the direct return to public R&D averaged 37.3% per annum. The social rates of return to R&D capital in agriculture and food processing are significantly larger than the private rates due to the existence of spillovers. While the divergence between rates is small in the farm machinery and equipment sector, its high direct rate may suggest relatively large intra-sector spillovers. We find that spillovers from public agricultural R&D to food processing exceeds the spillovers from food processing to the other two sectors. Thus, to a degree, public R&D in agriculture mitigates the market's failure in food processing to fully appropriate the returns to their R&D capital.

description: We perform a dynamical analysis of the recently published radial velocity (RV) measurements of a few solar type stars which host multiple Jupiter-like planets. In particular, we re-analyze the data for HD 202206, 14 Her, HD 37124 and HD 108874. We derive dynamically stable configurations which reproduce the observed RV signals using our method called GAMP (an acronym of the Genetic Algorithm with MEGNO Penalty). The GAMP relies on the N-body dynamics and makes use of genetic algorithms merged with a stability criterion. For this purpose, we use the maximal Lyapunov exponent computed with the dynamical fast indicator MEGNO. Through a dynamical analysis of the phase-space in a neighborhood of the obtained best-fit solutions, we derive meaningful limits on the parameters of the planets. We demonstrate that GAMP is especially well suited for the analysis of the RV data which only partially cover the longest orbital period and/or correspond to multi-planet configurations involved in low-order mean motion resonances (MMRs). In particular, our analysis reveals a presence of a second Jupiter-like planet in the 14 Her system (14 Her c) involved in a 3:1 or 6:1 MMR with the known companion b. We also show that the dynamics of the HD 202206 system may be qualitatively different when coplanar and mutually-inclined orbits of the companions are considered. We demonstrate that the two outer planets in the HD 37124 system may reside in a close neighborhood of the 5:2 MMR. Finally, we found a clear indication that the HD 108874 system may be very close to, or locked in an exact 4:1 MMR.

Households Forming Inflation Expectations: Who Are the 'Active' and 'Passive' Learners?

Subjects: SECS-P/05 Econometria

description: Recent research has established that households learn from professional forecasters as they form their inflation expectations. Professionals forecasts are transmitted, or ‘absorbed’, throughout the population slowly but eventually. This provides the microfoundations for ‘sticky information expectations’. The present paper considers whether absorption rates take place heterogeneously amongst households. We consider whether various segments of the population absorb the professional’s forecasts at different rates. Using a unique survey-based dataset covering various segments of the UK population we identify ‘active’ and ‘passive’ learners in the population.
‘Active’ and ‘passive’ learners are identified and distinguished by their respective absorption rates.
The present analyses also consider whether these absorption rates are non-linear.

Under høymessen som han forrettet denne søndagen, oppstod det brann i den gamle trekirken, og fordi dørene vendte innover, omkom mer enn 100 mennesker i trengselen for å komme seg ut. Hesselbergs preken ved begravelsen av brannofrene ble trykt, og den ble meget positivt bedømt. Den dramatiske hendelsen er senere blitt litterært og filosofisk behandlet av Peter Wessel Zapffe i boken Lyksalig Pinsefest (1972). Kilde: http://nbl.snl.no/Iver_Hesselberg/utdypning
A Thermodynamic Entropy Approach to Reliability Assessment with Applications to Corrosion Fatigue

description: This paper outlines a science-based explanation of damage and reliability of critical components and structures within the second law of thermodynamics. The approach relies on the fundamentals of irreversible thermodynamics, specifically the concept of entropy generation as an index of degradation and damage in materials. All damage mechanisms share a common feature, namely energy dissipation. Dissipation, a fundamental measure for irreversibility in a thermodynamic treatment of non-equilibrium processes, is quantified by entropy generation. An entropic-based damage approach to reliability and integrity characterization is presented and supported by experimental validation. Using this theorem, which relates entropy generation to dissipative phenomena, the corrosion fatigue entropy generation function is derived, evaluated, and employed for structural integrity and reliability assessment of aluminum 7075-T651 specimens.
Envisioning capitalism : geography and the renewal of Marxian political-economy
Creators: name: Castree, Noel
Publisher: name: University of British Columbia
Year: 2009

description: Not for the first time, Marxism is considered to be in a state of 'crisis'. This thesis seeks to 'underlabour' on behalf of a particular version of Marxism, a version articulated with force, coherence and great originality for over two decades within human geography: what David Harvey (1985a: xii), in a paradigmatic formulation, has called 'historicalgeographical materialism'. A research programme, rather than the work of any one individual, historical-geographical materialism has in various ways and at various levels creatively extended the classical Marxist canon in a geographical direction. Yet today it is considered increasingly passe by critics on the Left as well as the Right of human geography, reflecting the wider ennui with Marxism outside the discipline. In particular, it is seen as being too 'modern' - too foundationalist, totalising and authoritative in its cognitive and normative claims - to contribute effectively to a critical human geography for the 1990s. Against this, this thesis seeks to develop an alternative reading of the core claims of this research programme by offering a novel reinterpretation of Marx's mature political-economy. Rewriting Marx's account of what Postone (1996: 1) calls "the fundamental core of capitalism", the thesis puts this reinterpretation of the explanatorydiagnostic basis of Marx's critique to work on three major themes of historicalgeographical materialism: the production of space, the production pf nature and the production of subjectivity. It does so in order to illustrate the explanatory power, thematic reach and theoretical coherence of this reinterpretation, as well as its relevance to the late capitalist world. In closing, the normative or anticipatory-utopian basis of this reinterpreted historical-geographical materialism is considered and its political implications for today thereby scrutinised.

description: The goal of the LIFE ALNUS project has been to restore the structure, functions and good governance of riparian ecosystems, bearing in mind that they are areas of human activity which in some cases are subjected to intensive public use. Accordingly, the restoration of these riparian forests has taken into account the different points of view of all the stakeholders involved in the ecosystem: public bodies, landowners, users, scientists, ecologists, etc. LIFE ALNUS has planned and intervened in the restoration of eco-fluvial dynamics, in accordance with European legislation (Water Framework Directive, Habitats Directive and Floods Directive). The ultimate goal is to enable the river ecosystem (the river and its banks) to recover its good ecological status, and to do so in a way that strikes a balance between the interests and goals of the various stakeholders in the area.

description: We examine a new 2nd order integrator recently found by Omelyan et al. The integration error of the new integrator measured in the root mean square of the energy difference, $\braΔH^2\ket^{1/2}$, is about 10 times smaller than that of the standard 2nd order leapfrog (2LF) integrator. As a result, the step size of the new integrator can be made about three times larger. Taking into account a factor 2 increase in cost, the new integrator is about 50% more efficient than the 2LF integrator. Integrating over positions first, then momenta, is slightly more advantageous than the reverse. Further parameter tuning is possible. We find that the optimal parameter for the new integrator is slightly different from the value obtained by Omelyan et al., and depends on the simulation parameters. This integrator could also be advantageous for the Trotter-Suzuki decomposition in Quantum Monte Carlo.

A Dynamic Model of Internally-Driven Corporate Social Responsibility and Enlightened Profit Maximization
Creators: name: Balboni, Fabio

Subjects: SECS-P/01 Economia politica

description: The aim of this paper is to contribute to the analysis of Corporate Social Responsibility (CSR) from an economic perspective, in two ways. Firstly, introducing a new definition and a new framework of analysis, which can account for both the externallydriven and the internallydriven view of CSR. Secondly, developing a dynamic model of internallydriven CSR – which draws inspiration from the literature on renewable resources – to show that, under certain circumstances, an enlightened profit‐maximizing firm will behave as ‘Socially‐Responsible’ to the eyes of the society. The paper also discusses some possible limits and extensions of this theoretical framework.
Coloured Scalar Mediated Nucleon Decays to Invisible Fermion

description: We investigate nucleon decays to light invisible fermion mediated by the coloured scalar $\bar S_1= (\bar 3, 1, -2/3)$ and compare them with the results coming from the mediation of $S_1 = (\bar 3,1,1/3)$. In the case of $\bar S_1= (\bar 3, 1, -2/3)$ up-like quarks couple to the invisible fermion, while in the case of $S_1 = (\bar 3,1,1/3)$ the down-like quarks couple to the invisible fermion. For the mass of invisible fermion smaller than the mass $m_p - m_K$, proton (neutron) can decay to $K$ and invisible fermion and the masses of $\bar S_1$ and $S_1$ are in the region $\sim 10^{15}$ GeV. The decays of nucleons to pions and invisible fermion can occur at the tree-level, but in the case of $\bar S_1$ they come from dimension-9 operator and are therefore suppressed by several orders of magnitude compared to the decays into kaons. For the invisible fermion mass in the range $(937.8 \, {\rm MeV},\, 938.8 \, {\rm MeV})$, decay of neutron $n \toχγ$ induced by $\bar S_1$ is possible at the loop level, while the proton remains stable. The branching ratio of such decay is $\le 10^{-6}$, which does not explain neutron decay anomaly, but is in agreement with the Borexino experiment bound. We comment on low-energy processes with the nucleon-like mass of $χ$ in the final state as $Λ\to χγ$ and heavy hadron decays to invisibles.

description: In this work, the triangle singularity mechanism is investigated in the $ψ(2S) \to p \bar{p} η/ p \bar{p} π^0$ process. The triangle loop composed by $J/ψ$, $η$ and $p$ has a singularity in the physical kinematic range for the $ψ(2S) \to p \bar{p} η/ p \bar{p} π^0$ process, and it would generate a very narrow peak in the invariant mass spectrum of $pη(π)$ around $1.56387$ GeV, which is far away from both the threshold and relative resonances. In these processes, all the involved vertices are constrained by the experimental data. Thus, we can make a precise model independent prediction here. It turns out that the peak in the $pη$ invariant mass spectrum is visible, while it is very small in the $pπ^0$ invariant mass spectrum. We expect this effect shown in $p \bar{p} η$ final state can be observed by the Beijing Spectrometer (BESIII) and Super Tau-Charm Facility (STCF) in the future.

description: In cyclic cosmology based on phantom dark energy the requirement that our universe satisfy a CBE-condition ({\it Comes Back Empty}) imposes a lower bound on the number $N_{\rm cp}$ of causal patches which separate just prior to turnaround. This bound depends on the dark energy equation of state $w = p/ρ= -1 - ϕ$ with $ϕ> 0$. More accurate measurement of $ϕ$ will constrain $N_{\rm cp}$. The critical density $ρ_c$ in the model has a lower bound $ρ_c \ge (10^9 {\rm GeV})^4$ or $ρ_c \ge (10^{18} {\rm GeV})^4$ when the smallest bound state has size $10^{-15}$m, or $10^{-35}$m, respectively.

description: We present the first simultaneous, multi-wavelength observations of an L dwarf, the L3.5 candidate brown dwarf 2MASS J00361617+1821104, conducted with the Very Large Array, the Chandra X-ray Observatory, and the Kitt Peak 4-m telescope. We detect strongly variable and periodic radio emission (P=3 hr) with a fraction of about 60% circular polarization. No X-ray emission is detected to a limit of L_X/L_{bol}<2e-5, several hundred times below the saturation level observed in early M dwarfs. Similarly, we do not detect H-alpha emission to a limit of L_{H-alpha}/L_{bol}<2e-7, the deepest for any L dwarf observed to date. The ratio of radio to X-ray luminosity is at least four orders of magnitude in excess of that observed in a wide range of active stars (including M dwarfs) providing the first direct confirmation that late-M and L dwarfs violate the radio/X-ray correlation. The radio emission is due to gyrosynchrotron radiation in a large-scale magnetic field of about 175 G, which is maintained on timescales longer than three years. The detected 3-hour period may be due to (i) the orbital motion of a companion at a separation of about five stellar radii, similar to the configuration of RS CVn systems, (ii) an equatorial rotation velocity of about 37 km/s and an anchored, long-lived magnetic field, or (iii) periodic release of magnetic stresses in the form of weak flares. In the case of orbital motion, the magnetic activity may be induced by the companion, possibly explaining the unusual pattern of activity and the long-lived signal. We conclude that fully convective stars can maintain a large-scale and stable magnetic field, but the lack of X-ray and H-alpha emission indicates that the atmospheric conditions are markedly different than in early-type stars and even M dwarfs.

Isostasy with Love: I Elastic equilibrium

description: Isostasy explains why observed gravity anomalies are generally much weaker than what is expected from topography alone, and why planetary crusts can support high topography without breaking up. Classical isostasy, however, neglects internal stresses and geoid contributions to topographical support, and yields ambiguous predictions of geoid anomalies. Isostasy should instead be defined either by minimizing deviatoric elastic stresses within the elastic shell, or by studying the dynamic response of the body in the long-time limit. I implement here the first option by formulating Airy isostatic equilibrium as the response of an elastic shell to surface and internal loads. Isostatic ratios are defined in terms of deviatoric Love numbers which quantify deviations with respect to a fluid state. The Love number approach separates the physics of isostasy from the technicalities of elastic-gravitational spherical deformations, and provides flexibility in the choice of the interior structure. Since elastic isostasy is invariant under a global rescaling of the shell shear modulus, it can be defined in the fluid shell limit, which reveals a deep connection with viscous isostasy. If the shell is homogeneous, minimum stress isostasy is dual to a variant of elastic isostasy called zero deflection isostasy, which is less physical but simpler to compute. Each isostatic model is combined with general boundary conditions applied at the surface and bottom of the shell, resulting in one-parameter isostatic families. At long wavelength, the influence of boundary conditions disappears as all isostatic families members yield the same isostatic ratios. At short wavelength, topography is supported by shallow stresses so that Airy isostasy becomes similar to either pure top or bottom loading. The isostatic ratios of incompressible bodies with three homogeneous layers are implemented in freely available software.

description: We use the modified quark-meson coupling (MQMC) model to study the composition profile of neutron star matter and compare the results with those calculated by quantum hadrodynamics (QHD). Both MQMC and QHD model parameters are adjusted to produce exactly the same saturation properties so that we can investigate the model dependences of the matter composition at high densities. We consider the possibility of deep kaon optical potential and find that the composition of matter is very sensitive to the interaction strength of kaons with matter. The onset densities of the kaon condensation are studied in detail by varying the kaon optical potentials. We find that the MQMC model produces the kaon condensation at lower densities than QHD. The presence of kaon condensation changes drastically the population of octet baryons and leptons. Once the kaon condensation takes place, the population of kaons builds up very quickly, and kaons become the dominant component of the matter. We find that the $ω$-meson plays an important role in increasing the kaon population and suppressing the hyperon population.

description: Few institutions puzzle outsiders as much as the modern university. Even insiders may not grasp the primal essence of its life and behavior. The sheer size and diversity of many universities defeats orderly consideration. We adopt crude simplifications or, worse, numbing obfuscation. This is entirely unnecessary. The core of university life can be illuminated clearly through the prism of a rich and beguiling metaphor. This metaphor requires only that we see today's university as a thinly disguised feudal society such as existed in Europe during the 11th or 12th century A.D. In this medieval context, many otherwise baffling modern mysteries in academe become transparent.

description: Using the intertwining matrix of the IRF-Vertex correspondence we propose a determinant representation for the generating function of the commuting Hamiltonians of the double elliptic integrable system. More precisely, it is a ratio of the normally ordered determinants, which turns into a single determinant in the classical case. With its help we reproduce the recently suggested expression for the eigenvalues of the Hamiltonians for the dual to elliptic Ruijsenaars model. Next, we study the classical counterpart of our construction, which gives expression for the spectral curve and the corresponding $L$-matrix. This matrix is obtained explicitly as a weighted average of the Ruijsenaars and/or Sklyanin type Lax matrices with the weights as in the theta function series definition. By construction the $L$-matrix satisfies the Manakov triple representation instead of the Lax equation. Finally, we discuss the factorized structure of the $L$-matrix.

In the low frequency regime of the LISA band there are expected to be tens of thousands galactic binary systems that will be emitting gravitational waves detectable by LISA. The challenge of parameter extraction of such a large number of sources in the LISA data stream requires a search method that can efficiently explore the large parameter spaces involved. As signals of many of these sources will overlap, a global search method is desired. GAs represent such a global search method for parameter extraction of multiple overlapping sources in the LISA data stream. We find that GAs are able to correctly extract source parameters for overlapping sources. Several optimizations of a basic GA are presented with results derived from applications of the GA searches to simulated LISA data.

description: Unusual masses of black holes being discovered by gravitational wave experiments pose fundamental questions about the origin of these black holes. Black holes with masses smaller than the Chandrasekhar limit $\approx1.4\,M_\odot$ are essentially impossible to produce through stellar evolution. We propose a new channel for production of low mass black holes: stellar objects catastrophically accrete non-annihilating dark matter, and the small dark core subsequently collapses, eating up the host star and transmuting it into a black hole. The wide range of allowed dark matter masses allows a smaller effective Chandrasekhar limit, and thus smaller mass black holes. We point out several avenues to test our proposal, focusing on the redshift dependence of the merger rate. We show that redshift dependence of the merger rate can be used as a probe of the transmuted origin of low mass black holes.

description: We compare quantum corrections to semiclassical spinning strings in AdS(5)xS(5) to one-loop anomalous dimensions in N=4 supersymmetric gauge theory. The latter are computed using the reduced (Landau-Lifshitz) sigma model and with the help of the Bethe ansatz. The results of all three approaches are in remarkable agreement with each other. As a byproduct we establish the relationship between linear instabilities in the Landau-Lifshitz model and analyticity properties of the Bethe ansatz.

description: A measurement is presented of elastic deeply virtual Compton scattering γ* p \to γp made using e^+ p collision data corresponding to a luminosity of 46.5 pb^{-1}, taken with the H1 detector at HERA. The cross section is measured as a function of the photon virtuality, Q^2, the invariant mass of the γ* p system, W, and for the first time, differentially in the squared momentum transfer at the proton vertex, t, in the kinematic range 2 < Q^2 < 80 GeV^2, 30 < W < 140 GeV and |t| < 1 GeV^2. QCD based calculations at next-to-leading order using generalized parton distributions can describe the data, as can colour dipole model predictions.

description: Precise thermometry for quantum systems is important to the development of new technology, and understanding the ultimate limits to precision presents a fundamental challenge. It is well known that optimal thermometry requires projective measurements of the total energy of the sample. However, this is infeasible in even moderately-sized systems, where realistic energy measurements will necessarily involve some coarse graining. Here, we explore the precision limits for temperature estimation when only coarse-grained measurements are available. Utilizing tools from signal processing, we derive the structure of optimal coarse-grained measurements and find that good temperature estimates can generally be attained even with a small number of outcomes. We apply our results to many-body systems and nonequilibrium thermometry. For the former, we focus on interacting spin lattices, both at and away from criticality, and find that the Fisher-information scaling with system size is unchanged after coarse-graining. For the latter, we consider a probe of given dimension interacting with the sample, followed by a measurement of the probe. We derive an upper bound on arbitrary, nonequilibrium strategies for such probe-based thermometry and illustrate it for thermometry on a Bose-Einstein condensate using an atomic quantum-dot probe.
Simulated Effects of Odd-Alkane Impurities in a Hexane Monolayer on Graphite

description: We present the results of molecular dynamics simulations of odd alkane impurities present within the hexane (even alkane) monolayer. We simulate various temperatures at ca. 3%, 5%, 10%, and 15% impurities of propane, pentane, heptane, nonane, and undecane, each having a low-temperature solid phase belonging to a different space group as compared to hexane, to study the effects of impurities on the various phases and phase transitions for hexane monolayers that are well-characterized through previous experimental and theoretical work. Based upon preferential adsorption, we provide two emerging pictures of how impurities could affect the monolayer, for impurity chain lengths longer and shorter than that of the hexane molecules. We provide evidence that impurities in the monolayer, even in small proportion to the hexane, could induce significant changes in the phase behavior and phase transitions, and we propose that because of the size of pentane with respect to hexane, and the nature of the solid herringbone phase, pentane impurities give the best representation of the phase behavior observed for the pure hexane monolayer. We find that impurities with chain lengths longer than hexane tend to distort the sublattices of the solid herringbone phase, and hence lead to a phase transition into an intermediate phase significantly prior to that observed for a pure hexane monolayer. We discuss an interpretation of this study that could be potentially useful for future experimental work.

description: Combined elaboration of the first and second parts of papers prepared for presentation at the IAMO FORUM 2007 Halle, Germany 24-29 June 2007 and the IAAE-EAAE 104th seminar Budapest, Hungary 6-8 September 2007. In 2003 a research study looked at the position of smallholders; the survey was carried out using questionnaires and interviews. The farms included in the survey were situated in 3 counties in the Southern Great Plain of Hungary and in 3 counties of the western part of the country (Transdanubia). The results of the survey showed that there was a firm tendency of concentration among the Hungarian individual farms. Though their average size is about 3 ha, the number and area of farms over 50 ha size are rapidly growing and taking a significant part of the total individual agricultural area. The number of small farms is great but their total farming area is relatively small. The concentration takes place primarily due to renting. The land market is sluggish mainly owing to the land-buying restrictions and the small intention to sell of those owners who are waiting for higher prices. Land prices are low but rising, especially on the Western border of the country, near to Austria. The dominance of arable production and within that cereal production, especially on the larger individual farms, points to a prevalence of extensive farming The present support and subsidy system fortifies this tendency. When comparing the Southern Plain with western Transdanubia, it can be said that agricultural production is greater in the former region and more people are involved in agriculture. There is a higher share of under-cover production of vegetables and ornamental plants and animal husbandry. However, it seems that in western Transdanubia the spirit of enterprise is stronger than in the Southern Plain: more farmers enter into contractual agreements, more farmers make use of credits and subsidies, and the farms operate with greater profitability. Nevertheless, the proximity of western Transdanubia to industrial and service centers and, furthermore, its closeness to Austria tend to suppress agricultural activities. The regression analyses with respect to efficiency and profitability and the cluster analyses supported the assessments of the descriptive analyses and produced the following main conclusions: the larger farms, farmed by younger and better-educated individuals, are more efficient and profitable than the others. Furthermore, farmers with significant conceptions for development seem to achieve greater profitability.
On barbarians : the discourse of ’civilization’ in international theory
Creators: name: Salter, Mark B.
Publisher: name: University of British Columbia
Year: 2009

description: Unsatisfied with critical responses to Huntington's "Clash of Civilizations?" this dissertation attempts to trace two central elements of his argument. First, "On Barbarians" traces the evolution of the civilized/ barbarian dichotomy from its origins in the nineteenth century to its recent incarnations in International Relations theory. The relevance of Europe's imperial heritage is emphasized, along with certain thematic threads in popular discourse: demography, surveillance, and the distinction between popular and elite culture. The ubiquitous self/other dichotomy, which is central to political identity, has been understood in European imperial discourse to mean European civilization and barbaric others. This rhetoric remains powerful, even in current IR discourse. By reinscribing this civilized/barbarian dichotomy, Huntington in effect uses International Relations theory as a form of identity politics. Second, this dissertation analyzes the presence of culture and identity in the discipline of International Relations theory. Despite specific empirical considerations, Huntington's underlying interest in culture and identity is well-founded, which this dissertation attempts to demonstrate using material from the history of International Relations, post-colonial, and critical theorists. In sum, "On Barbarians" illustrates the critical benefit of studying culture and identity to LR through a critical examination of the civilized/barbarian discourse.

description: Despite the recent progress on neural network architectures for speech separation, the balance between the model size, model complexity and model performance is still an important and challenging problem for the deployment of such models to low-resource platforms. In this paper, we propose two simple modules, group communication and context codec, that can be easily applied to a wide range of architectures to jointly decrease the model size and complexity without sacrificing the performance. A group communication module splits a high-dimensional feature into groups of low-dimensional features and captures the inter-group dependency. A separation module with a significantly smaller model size can then be shared by all the groups. A context codec module, containing a context encoder and a context decoder, is designed as a learnable downsampling and upsampling module to decrease the length of a sequential feature processed by the separation module. The combination of the group communication and the context codec modules is referred to as the GC3 design. Experimental results show that applying GC3 on multiple network architectures for speech separation can achieve on-par or better performance with as small as 2.5% model size and 17.6% model complexity, respectively.
