Peripezie di immagini: il metodo-Warburg e la Divina Commedia
Creators: name: Chiarini, Gioachino
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: The paper is part of a ‘work in progress’ on the influence of oriental cultures and religions on Western ancient literature (The Seven Gates). After a short history of use and symbolic role of the “planetary ladder” from Sumerians to Islamic literatures and cultures via Greece, Rome and Jewish mysticism, the essai tries to show that the early Christians writers preferred to avoid employing the planetary ladder as a cipher of an itinerary to God. It was only Dante, in his Divina Commedia, who resumed to use with high perfection the planetary ladder: he re-elaboreted the circular Islamic hell in the Inferno, the Islamic heaven in the Paradiso and the Islamic paradise in the Purgatorio (his source was the Latin translation of The book of the ladder of Mahomet).

description: In order to celebrate the seventieth anniversary of Benjamin's death, the conference "Dialectic images and sudden constellations: Warburg, Benjamin, Adorno" was held in Florence. The idea, common to the three authors, of a truth content that can only be realised in its concrete and istantaneous configuration, was embodied here in the form of a "philosophical concert", where contributions by philosophers, philologists and historians of arts and architecture succeeded each other.

The isomorphism conjecture for 3-manifold groups and K-theory of virtually poly-surface groups

description: This article has two purposes. In \cite{R3} (math.KT/0405211) we showed that the FIC (Fibered Isomorphism Conjecture for pseudoisotopy functor) for a particular class of 3-manifolds (we denoted this class by \cal C) is the key to prove the FIC for 3-manifold groups in general. And we proved the FIC for the fundamental groups of members of a subclass of \cal C. This result was obtained by showing that the double of any member of this subclass is either Seifert fibered or supports a nonpositively curved metric. In this article we prove that for any M in {\cal C} there is a closed 3-manifold P such that either P is Seifert fibered or is a nonpositively curved 3-manifold and π_1(M) is a subgroup of π_1(P). As a consequence this proves that the FIC is true for any B-group (see definition 3.2 in \cite{R3}). Therefore, the FIC is true for any Haken 3-manifold group and hence for any 3-manifold group (using the reduction theorem of \cite{R3}) provided we assume the Geometrization conjecture. The above result also proves the FIC for a class of 4-manifold groups (see \cite{R2}(math.GT/0209119)). The second aspect of this article is to relax a condition in the definition of strongly poly-surface group (\cite{R1} (math.GT/0209118)) and define a new class of groups (we call them {\it weak strongly poly-surface} groups). Then using the above result we prove the FIC for any virtually weak strongly poly-surface group. We also give a corrected proof of the main lemma of \cite{R1}.

Heidegger e Chillida. Un dialogo sullo spazio
Creators: name: Esengrini, Stefano
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: Heidegger’s encounter with art determines a decisive turning point inside his own path of thinking. Klee and Cézanne in painting and Chillida in sculpture are just some of the numerous artists Heidegger met and studied since the Thirties. These artists contributed to establish a lively dialogue with the German philosopher on the main questions concerning their works. Space becomes the theme Heidegger and Chillida investigate as the origin of the work of art – in this case, of the sculptural or, better, plastic one. As a matter of fact, the space Heidegger and Chillida refer to has nothing to do with space as conceived by modern science; therefore space is thought in terms of place where man dwells, is. In this perspective art and thought show themselves as the knowledge capable of founding a place, a space-and-time for man’s dwelling on the earth, under the sky.

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: The present contribution aims to analyse the play Hölderlin by Peter Weiss as a Dichterdrama, a poet’s play, thus exploring facets which lie beyond the traditional ideological-political reading and putting the play in the context of further writings of the 1960es and 70es. Autobiographical, poetological, and political dimensions come together in Weiss’s Hölderlin-portrait to form the very epitome of visionary utopian poetry.

description: Assume that players strictly rank each other as coalition partners. We propose a procedure whereby they “fall back” on their preferences, yielding internally compatible, or coherent, majority coalition(s), which we call fallback coalitions. If there is more than one fallback coalition, the players common to them, or kingmakers, determine which fallback coalition will form. The players(s) who are the first to be acceptable to all other members of a fallback coalition are the leader(s) of that coalition. The effects of different preference assumptions—particularly, different kinds of single-peakedness—and of player weights on the number of coherent coalitions, their connectedness, and which players become kingmakers and leaders are investigated. The fallback procedure may be used (i) empirically to identify kingmakers and leaders or (ii) normatively to select them.
"Super weakly" coupled superconductivity in ultrathin superconductor-normal-metal bilayers

description: Tunneling measurements of the temperature dependence of the electronic density of states (DOS) of ultrathin bilayers of Pb and Ag reveal that their superconducting energy gap, $Δ(T)$, evolves similarly to BCS predictions despite the presence of a large anomalous DOS at the Fermi energy that persists as $T\to 0$. The gap ratio, ${2Δ(0)}\over {k_BT_c}$, systematically decreases more than 20% below the BCS universal value of 3.52 in bilayers with the lowest superconducting transition temperatures, $T_c$; a behavior we deem super weakly coupled. A semi-quantitative model suggests that the reduced gap ratios result from a systematic depletion of the DOS available for pairing that occurs with the growth of the anomalous DOS at the Fermi energy.

description: This article examines the impact of Indonesia’s electricity reform and meeting its 2030 carbon emissions and 2050 renewable energy targets on the country’s economic growth, carbon emissions and poverty and income distribution. Simulation results from a dynamic computable general equilibrium model show that energy reform and carbon tax in Indonesia have a regressive impact while the gasoline tax has a progressive impact. Of the two demand side policies, gasoline tax was found to be more harmful than the carbon tax, resulting in GDP loss, declining investment, higher energy prices, and rising urban and rural poverty. A hybrid policy comprising a renewable energy mix target (supply side policy) and a carbon tax (demand side policy) is a viable option for minimising GDP loss, income disparity and carbon emissions. However, the transition towards renewable energy use is fraught with challenges for Indonesia.

description: In this study, an econometric model of the South African maize and sorghum sector is estimated. Using the developed model, a market outlook for the two major grain sectors – maize and sorghum - for 1999/00 to 2006/07, is generated under the specified assumptions. Results indicate that for both maize and sorghum, consumption will gradually increase over time. In spite of varying areas of maize and sorghum being harvested, total production will also gradually increase over time due to increases in particularly yields.
Hölderlin e le idee estetiche. Riflessioni su un progetto mai realizzato

description: The aim of the article is that of thinking upon a theoretical project that Hölderlin just started to draw in its fundamental aspects but that he never fully developed. In a letter of the 10th of October 1794 addressed to Neuffer he tells of a project concerning an essay about the esthetical ideas. Relating the keynotes on the project articulated in this letter it is possible to reconstruct the way in which Hölderlin’s thought is connected to the Kantian aesthetic and also to make it clear that and why there is a need for going over Kant’s aesthetical theory.

description: A curious correspondence has been known between Landau models and non-linear sigma models: Reinterpreting the base-manifolds of Landau models as field-manifolds, the Landau models are transformed to non-linear sigma models with same global and local symmetries. With the idea of the dimensional hierarchy of higher dimensional Landau models, we exploit this correspondence to present a systematic procedure for construction of non-linear sigma models in higher dimensions. We explicitly derive $O(2k+1)$ non-linear sigma models in $2k$ dimension based on the parent tensor gauge theories that originate from non-Abelian monopoles. The obtained non-linear sigma models turn out to be Skyrme-type non-linear sigma models with $O(2k)$ local symmetry. Through a dimensional reduction of Chern-Simons tensor field theories, we also derive Skyrme-type $O(2k)$ non-linear sigma models in $2k-1$ dimension, which realize the original and other Skyrme models as their special cases. As a unified description, we explore Skyrme-type $O(d+1)$ non-linear sigma models and clarify their basic properties, such as stability of soliton configurations, scale invariant solutions, and field configurations with higher winding number.

description: This paper evaluates the production structure of the South African agricultural sector for the period 1970-1998, using a translog function. The results show that the production structure is best represented by production technology that is Hicks-neutral and homothetic. This information is useful in evaluating the results of previous research on the structure of South African agricultural production, particularly relatively recent research on elasticities of substitution. In addition, it also provides the basis for meaningful future analysis of aspects related to the production structure of agriculture.

description: High-fidelity projective readout of a qubit's state in a single experimental repetition is a prerequisite for various quantum protocols of sensing and computing. Achieving single-shot readout is challenging for solid-state qubits. For Nitrogen-Vacancy (NV) centers in diamond, it has been realized using nuclear memories or resonant excitation at cryogenic temperature. All of these existing approaches have stringent experimental demands. In particular, they require a high efficiency of photon collection, such as immersion optics or all-diamond micro-optics. For some of the most relevant applications, such as shallow implanted NV centers in a cryogenic environment, these tools are unavailable. Here we demonstrate an all-optical spin readout scheme that achieves single-shot fidelity even if photon collection is poor (delivering less than 10$^3$ clicks/second). The scheme is based on spin-dependent resonant excitation at cryogenic temperature combined with spin-to-charge conversion, mapping the fragile electron spin states to the stable charge states. We prove this technique to work on shallow implanted NV centers as they are required for sensing and scalable NV-based quantum registers.

For all temperatures above $T_c$ we find that the connected part of the singlet (decuplet) free energy of the three quark system is given by the sum of the connected parts of the free energies of $qq$-triplets (-sextets). Using renormalized free energies we can compare free energies in different colour channels as well as those of $qq$- and $qqq$-systems on an unique energy scale.

description: This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension services, farm income, and timely availability of improved maize seeds significantly influence the adoption and intensity of use of improved maize. It also showed that the impact of off-farm income and age of the household head on adoption and intensity of use of improved maize seed was insignificant.

description: Spreading on the free surface of a complex fluid is ubiquitous in nature and industry, owing to the wide existence of complex fluids. Here we report on a fingering instability that develops during Marangoni spreading on a deep layer of polymer solution. In particular, the wavelength depends on molecular weight and concentration of the polymer solution. We use the Transmission Lattice Method to characterize the finger height at the micron scale. We model the evolution of spreading radius, involving viscoelastic and shear thinning effects, to suggest a more generalized law than the spreading of Newtonian fluids. We give physical explanation on the origin of the fingering instability as due to normal stresses at high shear rate generating high contact angle and deformation at the leading edge, and so selects the wavelength of the fingering instability. Understanding the spreading mechanism has particular implication in airway drug delivery, and surface coating with patterns.

Stable Fermion Bag Solitons in the Massive Gross-Neveu Model: Inverse Scattering Analysis

description: Formation of fermion bag solitons is an important paradigm in the theory of hadron structure. We study this phenomenon non-perturbatively in the 1+1 dimensional Massive Gross-Neveu model, in the large $N$ limit. We find, applying inverse scattering techniques, that the extremal static bag configurations are reflectionless, as in the massless Gross-Neveu model. This adds to existing results of variational calculations, which used reflectionless bag profiles as trial configurations. Only reflectionless trial configurations which support a single pair of charge-conjugate bound states of the associated Dirac equation were used in those calculations, whereas the results in the present paper hold for bag configurations which support an arbitrary number of such pairs. We compute the masses of these multi-bound state solitons, and prove that only bag configurations which bear a single pair of bound states are stable. Each one of these configurations gives rise to an O(2N) antisymmetric tensor multiplet of soliton states, as in the massless Gross-Neveu model.

description: This article analyses factors influencing farmers’ willingness-to-pay for dipping services, as well as the revealed preference for dipping frequency using the multivariate and the logistic regression models. The study is based on a cross sectional survey of 125 smallscale cattle farmers interviewed in the Venda region of the Northern Province. Empirical multivariate and the logistic regression analysis show that liquidity, human resource, satisfaction with the programme and structure of production significantly influences farmers’ willingness-to-pay. However, the most important factor influencing both the willingness-to-pay and the dipping frequency is liquidity (employment). The results of this study have important implications for the delivery of veterinary services particularly in developing regions.

Cultural identity as a mediating factor in help-seeking attitutes among Asian and Caucasian students
Creators: name: Barone, Crispian Louis
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore how level of cultural identity was related to help-seeking attitudes among Asian students and to compare between Asian and Caucasian students. A total of 367 undergraduate university students participated in this study, of whom 184 (127 female and 57 male) were Asians and 183 (137 female, 44 male and 2 unspecified gender) were Caucasians. A weak positive correlation was found between Asian cultural identity and positive help-seeking attitudes (r = .158, p = .034, n = 181) (2-tailed); no significant correlation existed between cultural identity and negative help-seeking attitudes (r = .077, p = .305, n = 178) (2-tailed); no significant differences were found among: (a) high Caucasian cultural identity, (b) low Caucasian cultural identity Asian groups, and (c) Caucasian group for both positive help-seeking attitudes (F(2, 186) - .612), p = .544). Mixed results were found indicating that there was no easily identifiable trend between cultural identity and positive and negative help-seeking attitudes. Theoretical, clinical, and research implications are discussed.

description: In an endeavour to improve the livestock production and particularly the marketing of livestock in the Northern Communal Areas of Namibia, this study analyses the perception of livestock farmers in this regard. The findings show that the decision making is significantly influenced by numerous socio-cultural considerations, which in many cases even overshadow the economic ones. This is manifested in the low off-take percentage, the lacking interest in commercial production, and the fact that the sale price offered to the farmer is not the most important consideration when deciding to whom to sell.

description: Novel analog-to-digital converter (ADC) architectures are motivated by the demand for rising sampling rates and effective number of bits (ENOB). The main limitation on ENOB in purely electrical ADCs lies in the relatively high jitter of oscillators, in the order of a few tens of fs for state-of-the-art components. When compared to the extremely low jitter obtained with best-in-class Ti:sapphire mode-locked lasers (MLL), in the attosecond range, it is apparent that a mixed electrical-optical architecture could significantly improve the converters' ENOB. We model and analyze the ENOB limitations arising from optical sources in optically enabled, spectrally sliced ADCs, after discussing the system architecture and implementation details. The phase noise of the optical carrier, serving for electro-optic signal transduction, is shown not to propagate to the reconstructed digitized signal and therefore not to represent a fundamental limit. The optical phase noise of the MLL used to generate reference tones for individual slices also does not fundamentally impact the converted signal, so long as it remains correlated among all the comb lines. On the other hand, the timing jitter of the MLL, as also reflected in its RF linewidth, is fundamentally limiting the ADC performance, since it is directly mapped as jitter to the converted signal. The hybrid nature of a photonically enabled, spectrally sliced ADC implies the utilization of a number of reduced bandwidth electrical ADCs to convert parallel slices, resulting in the propagation of jitter from the electrical oscillator supplying their clock. Due to the reduced sampling rate of the electrical ADCs, as compared to the overall system, the overall noise performance of the presented architecture is substantially improved with respect to a fully electrical ADC.

Il destino di Hölderlin
Creators: name: Lunačarskij, Anatolij
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: Lunačarskij’s essay reads Hölderlin from a marxist point of view. According to Lunačarskij, who uses also some Pavlov’s ideas, the poet is the expression of his own time showing, in his tragic life course too, the economical and social dysfunctions of a whole historical period. Translated by Giuseppe Tinè.

description: This study evaluates the long run and short run effects of real exchange rate changes on South African agricultural exports using an Error Correction Model (ECM). The results suggest that there is a unidirectional causal flow from exchange rate to agricultural exports. Moreover, appreciation of the Rand will be detrimental to agricultural exports.

description: This paper calculates multi-lateral Malmquist multi-factor productivity (MFP) indices for agriculture in the eighteen regions and the commercial sector of Botswana from 1981 to 1996. The Malmquist is appropriate because prices do really exist for major inputs such as land and labour. The small size of the cross section is overcome by using the sequential version of the Malmquist, which accumulates the annual data, so increasing the stability of the frontier. The regional MFPs are the natural peer group for producing a national MFP, so the problem of choosing peers, in earlier work on international comparisons does not arise. The results show that the national MFP grew at an average rate 1.57% per annum. However, disaggregation by enterprise shows that the livestock MFP declined at a rate of 0.34% per annum while that for crops grew at 3.37% per annum. Decomposition of the Malmquist shows that there was positive technological change combined with decreasing efficiency. Comparisons of the regional results show a very clear pattern whereby the advantaged regions are able to exploit new technologies whereas the resource poor, geographically disadvantaged areas have been stagnant and have thereby fallen further and further behind the best practice frontier.
Patmos
Creators: name: Hölderlin, Friedrich
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: Here's the new translation by Fabrizio Desideri of Hölderlin's magnificent hymn Patmos, focal point of Hölderlin's remarks about the notion of lebendiges, the “living element”. In this hymn the death of Christ is depicted as a cesura, a rift between the sensitive antiquity and our suffering, gorforsaken modernity.

description: Bivariate probit analysis was used to assess the efficacy of a South African microlender’s loan screening process. This micro-lender grants short-term cash loans to individuals who are employed and earning a fixed salary. Loan applicants with more stable incomes, who are contactable via telephone or post, who are employed in less risky business sectors, who have more disposable income relative to debt, and who have had a good credit history with other lenders, are more likely to be accepted. None of the factors with a significant effect on the loan screening decision could explain subsequent loan default by accepted applicants. The microlender may have screened out very risky clients and accepted a riskier, profitable pool of loan applicants with risk being controlled through effective monitoring. This is important where tangible collateral is unavailable and where the risk must be acceptable to commercial lenders wanting to link up with profitable micro-lenders.
Due lettere di Friedrich Hölderlin
Creators: name: Hölderlin, Friedrich
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2012

description: Here's the first italian translation of two letters by Friedrich Hölderlin, written between November 1798 and January 1799 and adressed respectively to Christian Ludwig Neuffer (the first one) and to Hölderlin's youngest brother Karl (the second one). Aim of these two letters is to clarify and to take a deeper look into the notion of lebendiges, the “living element”, which is at the heart of Hölderlins' poetics. Translated by Mariagrazia Portera.

description: This paper endeavours to update the series of PSE calculations based on the 1998 OECD methodology (OECD 1998) which is a slightly revised methodology from the earlier calculations. The OECD terminology also now means that PSE stands for Producer Support Estimate and is calculated by classifying policy measures under a slightly different set of categories.

description: In this article we study from a non-perturbative point of view the entanglement of two directed polymers subjected to repulsive interactions given by a Dirac $δ-$function potential. An exact formula of the so-called second moment of the winding angle is derived. This result is used to provide a thorough analysis of entanglement phenomena in the classical system of two polymers subjected to repulsive interactions and related problems. No approximation is made in treating the constraint on the winding angle and the repulsive forces. In particular, we investigate how repulsive forces influence the entanglement degree of the two-polymer system. In the limit of ideal polymers, in which the interactions are switched off, we show that our results are in agreement with those of previous works.

Year: 2012

description: This number is dedicated to Hölderlin. Starting from a variety of perspectives this issue aims to underline the main role of the German poet in the definition of modernity: from the marxist Lunačarskij interpretation to Böschenstein’s Celan- Hölderlin analysis. Other tipics are the problem of poetry in modern times (Mecacci), the “living” theme in Hölderlin, Nietzsche and Kant (Portera), the position of Kant’s aesthetic ideas in Hölderlin (Santini) and an overview of Peter Weiss’ drama Hölderlin (Castellari). The issue includes also a translation of Patmos hymn and two letters of 1798.

description: We study the evolution of the superconducting state in a perforated disk by varying the size of the hole. The superconducting properties are investigated by means of transport measurements around the superconducting/normal phase boundary Tc(H). A transition from a one-dimensional to a two-dimensional regime is seen when increasing the magnetic field for disks with small holes. A good agreement is found between the measured Tc(H) line and the calculations performed in the framework of the linearized Ginzburg-Landau theory. The effect of breaking the axial symmetry of the structure by moving the hole away from the center of the disk is also studied. An enhanced critical field is found for the asymmetric structures, possibly due to the recovery of the singly connected state.

description: We study spin 1/2 isoscalar and isovector, even and odd parity candidates for the $Θ^+(1540)$ pentaquark particle using large scale lattice QCD simulations. Previous lattice works led to inconclusive results because so far it has not been possible to unambiguously identify the known scattering spectrum and tell whether additionally a genuine pentaquark state also exists. Here we carry out this analysis using several possible wave functions (operators). Linear combinations of those have a good chance of spanning both the scattering and pentaquark states. Our operator basis is the largest in the literature, and it also includes spatially non-trivial ones with unit orbital angular momentum. The cross correlator we compute is 14$\times$14 with 60 non-vanishing elements. We can clearly distinguish the lowest scattering state(s) in both parity channels up to above the expected location of the pentaquark, but we find no trace of the latter. Based on that we conclude that there are most probably no pentaquark bound states at our quark masses, corresponding to $m_π$=400--630 MeV. However, we cannot rule out the existence of a pentaquark state at the physical quark mass corresponding to $m_π$=135 MeV or pentaquarks with a more exotic wave function.

description: The generative adversarial imitation learning (GAIL) has provided an adversarial learning framework for imitating expert policy from demonstrations in high-dimensional continuous tasks. However, almost all GAIL and its extensions only design a kind of reward function of logarithmic form in the adversarial training strategy with the Jensen-Shannon (JS) divergence for all complex environments. The fixed logarithmic type of reward function may be difficult to solve all complex tasks, and the vanishing gradients problem caused by the JS divergence will harm the adversarial learning process. In this paper, we propose a new algorithm named Wasserstein Distance guided Adversarial Imitation Learning (WDAIL) for promoting the performance of imitation learning (IL). There are three improvements in our method: (a) introducing the Wasserstein distance to obtain more appropriate measure in the adversarial training process, (b) using proximal policy optimization (PPO) in the reinforcement learning stage which is much simpler to implement and makes the algorithm more efficient, and (c) exploring different reward function shapes to suit different tasks for improving the performance. The experiment results show that the learning procedure remains remarkably stable, and achieves significant performance in the complex continuous control tasks of MuJoCo.

description: We present a method to automatically derive the Feynman rules for mesonic chiral perturbation theory with a lattice regulator. The Feynman rules can be output both in a human-readable format and in a form suitable for an automated numerical evaluation of lattice Feynman diagrams. The automated method significantly simplifies working with improved or extended actions. Some applications to the study of finite-volume effects will be presented.
