description: Afin de repenser les modalités d’intervention publique, l’économie comportementale permet d’analyser comment les biais comportementaux et cognitifs peuvent limiter ou renforcer la portée des incitations économiques traditionnelles. Issu des sciences comportementales et popularisé par Thaler et Sunstein (2008), le concept de « nudge » offre un outil d’intervention intéressant et généralement peu coûteux. Complétant les dispositions réglementaires et les incitations économiques (monétaires), les « nudges » sont des interventions non contraignantes modifiant l’architecture des choix afin d’orienter les décisions des agents vers des comportements améliorant leur bien-être. Pour ce faire, sans restreindre les choix des agents, les « nudges » mobilisent certains biais comportementaux ou cognitifs, comme par exemple les préférences pour le statu quo ou la tendance des individus à se comparer entre eux. Les résultats des travaux présentés ci-dessous illustrent l’impact des normes sociales dans les décisions individuelles des agriculteurs et la façon dont on pourrait mobiliser les « nudges » pour construire des incitations comportementales s’appuyant sur ces normes sociales et renforçant l’impact des incitations économiques.

description: The paper examines the asymptotic behavior of the set of equilibrium payoffs in a repeated game when there are bounds on the complexity of the strategies players may select. The complexity of a strategy is measured by the size of the minimal automaton that can implement it. The main result is that in a zero—sum game, when the size of the automata of both players go together to infinity, the sequence of values converges to the value of the one—shot game. This is true even if the size of the automata of one player is a polynomial of the size of the automata of the other player. The result for the zero—sum games gives an estimation for the general case.
Single scattering of polarized light by correlated surface and volume disorder

description: We study light scattering by systems combining randomly rough surface and volume dielectric fluctuations. We introduce a general model including correlations between surface and volume disorders, and we study the scattering properties within a single scattering approach. We identify different regimes of surface and volume dominated scattering depending on length scales characterizing the surface and volume disorders. For uncorrelated disorders, we discuss the polarization response of each source of disorder, and show how polarimetric measurements can be used to separate the surface and volume contributions in the total measured diffusely scattered intensity. For correlated systems, we identify two configurations of volume disorder which, respectively, couple weakly or strongly to surface scattering via surface-volume cross-correlations. We illustrate these effects on different configurations exhibiting interference patterns in the diffusely scattered intensity, which may be of interest for the characterization of complex systems or for the design of optical components by engineering the degree of surface-volume correlations.

description: The Chandra discovery of bright X-ray emission from kpc-scale jets allows insight into the physical parameters of the jet flow at large scale. At the opposite extreme, extensive studies of the inner relativistic jets in Blazars with multiwavelength observations, yield comparable information on sub-parsec scales. In the framework of simple radiation models for the emission regions we compare the physical parameters of jets on these two very different scales in the only two well studied Blazars for which large-scale emission has been resolved by Chandra. Notably, we find that the relativistic Doppler factors and powers derived independently at the two scales are consistent, suggesting that the jet does not suffer severe deceleration or dissipation. Moreover the internal equipartition pressures in the inner jet and in the external X-ray bright knots scale inversely with the jet cross section as expected in the simple picture of a freely expanding jet in equipartition.

description: Youth Refugee Education has been largely missing within the literature and in practice. This is in part due to the way in which International Agencies and Non-governmental organizations define youth and frame their education. Through a careful review and analysis of numerous reports and other Web based materials being produced by a sample of organizations, the relationship between how the youth are portrayed and the purpose of education in emergencies are illustrated. In order to provide purposeful and relevant education for youth in emergencies, the organizations providing education must reexamine the current lens that they use to define youth and consider applying a different framework.

VET apprentices

description: When crossing the borders from educational to professional environments, VET apprentices can perceive discontinuities and contradictions between what they learn at school and in the workplace. This research explores whether a digital tool named e-DAP, designed as a space for reflective practices in VET educational systems supports apprentices’ perception of connectivity across learning locations. A group of 114 apprentices who used the e-DAP and a control group (CG) composed of 141 apprentices (CG = 141) completed a 15-items questionnaire which investigated the following dimension: 1. frequency of use of the e-DAP platform 2. mutual knowledge across locations, 3. explicit connectivity and 4. perceived usefulness of the tool. Participants were asked to express their level of agreement on a 6-point Likert scale on the items in sections 2 and 4 and on a 5-point Likert scale on the items in section 3. On average, the e-DAP users perceived the usefulness of the platform to be high (M = 4,55; SD = 1.12). The perception of connectivity resulted, in general, higher in the e-DAP group than in the CG. Specifically, mutual knowledge and explicit connectivity were perceived significantly higher. Frequent users (FU) of the e-DAP had a higher perception of explicit connectivity than low users (LU). This difference was even higher when comparing FU and LU according to their use of the e-DAP at the workplace. Results are in line with the expected learning path of the e-DAP, inspired by the Erfahrraum model. The more apprentices collect traces of workplace experiences through the e-DAP, the more VET teachers can support explicit reflection on practice at school. In future exploration, we are going to test the effect of the perceived usefulness of the e-DAP on apprentices’ perception of mutual knowledge and explicit connectivity.

Explaining the Persistent Weakness of Formal Vocational Education Systems in Sub-Saharan African Countries

description: Formal vocational education systems in Africa are a very small part of formal education and training provision. They are widely regarded as weak and are criticized for not supplying the skills needed by employers. Reforms and donor-supported projects are a constant feature in many countries, but in the main, the weaknesses persist. The paper draws on primary research in a selection of countries—mainly analysis of labour market data and official sources of vocational education data—as well as an analysis of historical literature on industrialization, development economics, and vocational education to make a conceptual point: while most reforms focus on provision systems, the factors underpinning the weaknesses of provision systems lie outside of them. The first underpinning factor is the process, pace, and levels of industrialization, which effects vocational education provision because there are low numbers of well-paying jobs requiring technical expertise. Weak industrialization has an indirect effect, which is the second crucial factor: lack of economic development and change in labour markets. Thirdly, an international consensus since the 2000s on palliative approaches to development which address the effects but not the causes of the lack of economic development in Africa has resulted in mass poor quality provision of education. Education systems are rapidly expanding and achievement levels rising, in the context of very few labour market rewards for most people and substantial labour market rewards confined mainly to graduates. This reinforces deeply embedded cultural preferences for general education, which originate in the type of education systems established by colonial powers, as well as the relationships between educational credentials and elite jobs.

description: In the last years, several quantum algorithms that try to address the problem of partial differential equation solving have been devised. On one side, "direct" quantum algorithms that aim at encoding the solution of the PDE by executing one large quantum circuit. On the other side, variational algorithms that approximate the solution of the PDE by executing several small quantum circuits and making profit of classical optimisers. In this work we propose an experimental study of the costs (in terms of gate number and execution time on a idealised hardware created from realistic gate data) associated with one of the "direct" quantum algorithm: the wave equation solver devised in [PCS. Costa, S. Jordan, A. Ostrander, Phys. Rev. A 99, 012323, 2019]. We show that our implementation of the quantum wave equation solver agrees with the theoretical big-O complexity of the algorithm. We also explain in great details the implementation steps and discuss some possibilities of improvements. Finally, our implementation proves experimentally that some PDE can be solved on a quantum computer, even if the direct quantum algorithm chosen will require error-corrected quantum chips, which are not believed to be available in the short-term.

description: Critics of capitalism contend that many products are designed to have uneconomically short lives, with the intention of forcing consumers to repurchase too frequently. This phenomenon is commonly referred to as "planned obsolescence." In this paper, we show that planned obsolescence may be a necessary condition for the achievement of technological progress and that a pattern of rapidly deteriorating products and fast innovation may be preferred to long-lasting products and slow innovation.
Hot Stars Mass-loss studied with Spectro-Polarimetric INterferometry (SPIN)

description: We present a prospective work undertaken on Spectro-Polarimetric INterferometry (SPIN). Our theoretical studies suggest that SPIN is a powerful tool for studying the mass loss from early type stars. Based on Monte Carlo simulations, we computed the expected SPIN signal for numerous hot star spectral types covering a broad range of geometries and optical depths. The SPIN technique is based on the detection and comparison of the fringe characteristics (complex visibility) between two perpendicular directions of polarization. In particular, we demonstrate that the SPIN technique is very sensitive to the beta parameter from the so-called 'beta velocity law' for optically thin winds. Moreover, the location where the bulk of polarization is generated can be defined accurately. The required sensitivity for studying main sequence OB star winds is still very demanding (inferior to 0.5%), but the signal expected from denser winds or extended atmospheres is well within the capabilities of existing interferometers. The visibility curves obtained in two perpendicular polarizations for LBVs or WR stars can differ by more than 15%, and their corresponding limb-darkened radii obtained by the fit of these curves by more than 35%. The signal expected from the extended circumstellar environment of Be stars and B[e] appears also to be easy to detect, relaxing the required instrumental accuracy to 1%. For these spectral types, the SPIN technique provide a good tool to extract the highly polarized and spatially confined envelope contribution from the bright star emission.

description: We formalize Schumpeter's explanation of technological progress and growth cycles in a model where consumers and firms benefit from periodic changes in technology which result in the development and marketing of new generations of products. We develop a genera/ equilibrium dynamic differentiated products model in order to explain technological progress via cyclical changes in investment, output, and interest rates as well as the introduction of new products. We characterize the equilibrium and analyze the effect of changes in the rate of technology growth, resource endowment, and costs of REM and production on the duration of generations of products and the frequency of technology revolutions, and hence of growth cycles.

description: We investigate the stability of negative image equilibria in mean synaptic weight dynamics governed by spike-timing dependent plasticity (STDP). The neural architecture of the model is based on the electrosensory lateral line lobe (ELL) of mormyrid electric fish, which forms a negative image of the reafferent signal from the fish's own electric discharge to optimize detection of external electric fields. We derive a necessary and sufficient condition for stability, for arbitrary postsynaptic potential functions and arbitrary learning rules. We then apply the general result to several examples of biological interest.

description: The polarized Raman spectra of stoichiometric LaTiO$_3$ (T$_N = 150$ K) were measured between 6 and 300 K. In contrast to earlier report on half-metallic LaTiO$_{3.02}$, neither strong background scattering, nor Fano shape of the Raman lines was observed. The high frequency phonon line at 655 cm$^{-1}$ exhibits anomalous softening below T$_N$: a signature for structural rearrangement. The assignment of the Raman lines was done by comparison to the calculations of lattice dynamics and the nature of structural changes upon magnetic ordering are discussed. The broad Raman band, which appears in the antiferromagnetic phase, is assigned to two-magnon scattering. The estimated superexchange constant $J = 15.4\pm0.5$ meV is in excellent agreement with the result of neutron scattering studies.

Strongly hyperbolic systems in General Relativity

description: We discuss several topics related to the notion of strong hyperbolicity which are of interest in general relativity. After introducing the concept and showing its relevance we provide some covariant definitions of strong hyperbolicity. We then prove that is a system is strongly hyperbolic with respect to a given hypersurface, then it is also strongly hyperbolic with respect to any near by one. We then study for how much these hypersurfaces can be deformed and discuss then causality, namely what is the maximal propagation speed in any given direction. To show that the concept is needed in the area of general relativity we discuss two results for which the theory of symmetric hyperbolic systems shows to be insufficient. The first deals with the hyperbolicity analysis of systems which are second order in space derivatives, they include certain versions of the ADM and the BSSN families of equations. The second result deals with systems having constraints. The question posed is which hyperbolicity properties, if any, are inherited from the original evolution system by the subsidiary system satisfied by the constraint quantities. The answer is that, subject to some condition on the constraints, if the evolution system is strongly hyperbolic then the subsidiary system is also strongly hyperbolic and the causality properties of both are identical.

description: Mental health issues among college students are a growing public health concern, making predictors such as diet important to consider. Seventy-three college-aged students completed four 24-hour dietary recalls and the following measures: Beck's Depression Inventory (BDI), Perceived Stress Scale (PSS) and Positive Affect and Negative Affect Scale-X (PANAS-X). Data from the dietary recalls were categorized into nine dietary patterns, which were then analyzed with three mood scales, positive affect, negative affect, and fatigue using descriptive statistics, correlation matrices and regression analysis. Significant correlations were found between fatigue and Total Soda intake, Non-animal Protein and Raw Fruit and Vegetable consumption. Regression found Raw Fruit and Vegetable consumption remained inversely associated with feelings of fatigue, which was upheld when controlling for perceived stress and depression. These findings support the body of research on diet, mood and fatigue by extending the relationship between into a nonclinical college age population.

description: We report the detection of high excitation CO emission from the most distant quasar currently known, SDSS J114816.64+525150.3 (hereafter J1148+5251), at a redshift z=6.419. The CO (J=6-5) and (J=7-6) lines were detected using the IRAM Plateau de Bure interferometer, showing a width of ~280 km/s. An upper flux limit for the CO (J=1-0) line was obtained from observations with the Effelsberg 100-meter telescope. Assuming no gravitational magnification, we estimate a molecular gas mass of ~2x10^10 M_sun. Using the CO (3-2) observations by Walter et al. (2003), a comparison of the line flux ratios with predictions from a large velocity gradient model suggests that the gas is likely of high excitation, at densities ~10^5 cm^-3 and a temperature ~100 K. Since in this case the CO lines appear to have moderate optical depths, the gas must be extended over a few kpc. The gas mass detected in J1148+5251 can fuel star formation at the rate implied by the far-infrared luminosity for less than 10 million years, a time comparable to the dynamical time of the region. The gas must therefore be replenished quickly, and metal and dust enrichment must occur fast. The strong dust emission and massive, dense gas reservoir at z~6.4 provide further evidence that vigorous star formation is co-eval with the rapid growth of massive black holes at these early epochs of the Universe.

description: The relationship between international trade and environmental degradation is analyzed in this short paper. Environmental attributes are modeled as differentiated, non-tradeable goods. The results derived from the model indicate that when consumers view consumption goods and environmental attributes as substitutes and if consumers place a relatively higher value on environmental variety than on commodity variety, the opening of trade may reduce the welfare of the trading countries. A net welfare loss may occur as exchange gains from trade are reduced or eliminated by environmental losses.

 Devincenzia Kraglievich, 1932:323, 338.
 Onactornis Cabrera, 1939:15; syn. n.
* Measurements from Ameghino (1895)
 Type Species – Devincenzia gallinali Kraglievich, 1932, junior synonym of Devincenzia pozzi (Kraglievich, 1931).
 Included Species – Only the type species.
 Distribution – Upper Miocene to the Lower Pliocene of Argentina and Uruguay.
 Diagnosis – They are the biggest of the known Phorusrhacinae, with a height comparable to that of the largest Brontornithinae, being, however, lighter. The skull is about 65 cm long, equivalent to that of Phorusrhacos, this being possibly flattened dorso-ventrally (Fig. 32A). The tarsometatarsus is substantially sturdier than that of Phorusrhacos (Figs. 2F and 22A).
 Remarks – The general appearance of the tarsometatarsus of Devincenzia (MNHN-189, Fig. 2F), appears to indicate an intermediate position between the Phorusrhacinae and Brontornithinae, as observed by Kraglievich (1932) himself. However, the appearance of the bony cortex makes it clear that one is dealing with a not yet completely adult individual. As happens with several present-day Ralliformes, especially the Rallidae and Cariamidae, besides other groups of birds, it is normal that the proximal metaphysary portion of the tarsometatarsus reaches, in youngsters, a larger width than that in the adults, associated to a shorter length of the bone. Consequently, one supposes that the tarsometatarsus of Devincenzia, in the adult phase, might be a little longer and with the proximal region slightly narrower than appears in the refered specimen. The origin of this tarsometatarsus (MNHN-189), type of Devincenzia gallinali Kraglievich, 1932, and, consequently, its geological age, are unknown. From the appearance of the bone (and certainly the remains of the encrusted substract), Kraglievich supposed it to have originated from the Arroyo Roman, Rio Negro, Uruguay, and points out the difference of color, especially when compared with the bones coming from Patagonia, without, however, comparing it with specimens from the Huayquerian of north Argentina, studied years before by he himself (1931).

It further investigates whether compromises in prestige and gender type are more important than compromises in occupational interests. The study is based on a sample of trainees from the German National Educational Panel Study (NEPS). Event history models are used to identify the factors influencing the hazard rates of premature termination of vocational training. Compromises in interests increased the risk of premature termination of vocational training. Compromise in gender type and prestige, on the contrary, had little impact. Compromise in interests were of particular importance if the trainees had entered occupations that correspond to the gender type and prestige of their occupational aspirations. Compromises in interests in first occupational choice threaten the stability of vocational training. Compromises in interests are particularly influential when aspirations regarding the social aspects of occupational choice are met.

description: This paper attempts to model and simulate realistically the macroeconomic process generated by the massive immigration of Soviet Jews to Israel, which started at the end of 1989. The framework is a dynamic optimization model of an open economy calibrated to Israeli data — including the national income accounts, tax rates, and projections of immigration from 1990 to 1994. The aim of this analysis is to analyze the quantitative effects of different policy instruments the adjustment process triggered by the immigration.
The Many Electron Ground State of the Adiabatic Holstein Model in Two and Three Dimensions

description: We present the complete ground state phase diagram of the Holstein model in two and three dimension considering the phonon variables to be classical. We first establish the overall structure of the phase diagram by using exact diagonalisation based Monte Carlo (ED-MC) on small lattices and then use a new ``travelling cluster'' approximation (TCA) for annealing the phonon degrees of freedom on large lattices. The phases that emerge include a Fermi liquid (FL), with no lattice distortions, an insulating polaron liquid (PL) at strong coupling, and a charge ordered insulating (COI) phase around half- filling. The COI phase is separated from the Fermi liquid by a regime of phase coexistence whose width grows with increasing electron-phonon coupling. We provide results on the electronic density of states, the COI order parameter, and the spatial organisation of polaronic states, for arbitrary density and electron-phonon coupling. The results highlight the crucial role of spatial correlations in this strong coupling problem.

description: A founder effect was detected in Blackfordia virginica suggesting that it is an introduced species in the United States. Compared to Nemopsis bachei, a native hydrozoan, B. virginica exhibited a 0.03% average percent variation less than N. bachei with 3 fewer haplotypes. For COI B. virginica exhibited a 0.23% average percent variation of less than N. bachei with 7 fewer haplotypes. For ribosomal ITS1, B. virginica exhibited a 0.39% average percent variation higher than N. bachei. Both species had 2 haplotypes. For 16S, when compared to 30 other species of Hydrozoa, B. virginica had the lowest average percent variation at 0% with the fewest number of haplotypes. When compared to 14 other species for COI, B. virginica had the second lowest average percent variation for at 0.03% and the second lowest number of haplotypes. When B. virginica is compared to individuals collected in the United States and Brazil, the percent variation for 16S is 10.05% and for COI is 12.6% suggesting that specimens from Brazil are a different species.

description: Vocational education and training play a key role in the Swiss educational system. One of the most frequently chosen apprenticeships is Certified Social Care Worker (CSCW). After certification, these graduates have the option of working in the profession, attending tertiary vocational education, or changing to a profession outside the social sector. Studies on the choice of study at upper secondary and university tertiary level point to gender-typical choice behaviour. So far, little research has been done on whether and how gender-typical choices are perpetuated when entering a profession or attending vocational tertiary education. This study aims to close this gap and, using the example of the social sector, examines the role that gender plays in career and educational decisions after graduation as CSCW. Since the social sector is considered a women’s domain but includes various areas of work that are occupied to different degrees by women and men, it is of particular interest whether the career and educational decisions of former CSCW apprentices are also influenced by the area of work in which they were trained. The analyses are based on data from a longitudinal study. The results show a significant influence of gender and the chosen work area on the CSCWs career and educational pathway. The findings are discussed in the context of individual and institutional characteristics in the social sector.
Collective stiffening of soft hair assemblies

description: Many living systems use assemblies of soft and slender structures whose deflections allow them to mechanically probe their immediate environment. In this work, we study the collective response of artificial soft hair assemblies to a shear flow by imaging their deflections. At all hair densities, the deflection is found to be proportional to the local shear stress with a proportionality factor that decreases with density. The measured collective stiffening of hairs is modeled both with a microscopic elastohydrodynamic model that takes into account long range hydrodynamic hair-hair interactions and a phenomenological model that treats the hair assemblies as an effective porous medium. While the microscopic model is in reasonable agreement with the experiments at low hair density, the phenomenological model is found to be predictive across the entire density range.

description: A system of nonlocal electron-transport equations for small perturbations in a magnetized plasma is derived using the systematic closure procedure of V. Yu. Bychenkov et al., Phys. Rev. Lett. 75, 4405 (1995). Solution to the linearized kinetic equation with a Landau collision operator is obtained in the diffusive approximation. The Fourier components of the longitudinal, oblique, and transversal electron fluxes are found in an explicit form for quasistatic conditions in terms of the generalized forces: the gradients of density and temperature, and the electric field. The full set of nonlocal transport coefficients is given and discussed. Nonlocality of transport enhances electron fluxes across magnetic field above the values given by strongly collisional local theory. Dispersion and damping of magnetohydrodynamic waves in weakly collisional plasmas is discussed. Nonlocal transport theory is applied to the problem of temperature relaxation across the magnetic field in a laser hot spot.

description: A robust and efficient frequency dependent and non-local exchange-correlation $f_{xc}(r,r';ω)$ is derived by imposing time-dependent density-functional theory (TDDFT) to reproduce the many-body diagrammatic expansion of the Bethe-Salpeter polarization function. As an illustration, we compute the optical spectra of LiF, \sio and diamond and the finite momentum transfer energy-loss spectrum of LiF. The TDDFT results reproduce extremely well the excitonic effects embodied in the Bethe-Salpeter approach, both for strongly bound and resonant excitons. We provide a working expression for $f_{xc}$ that is fast to evaluate and easy to implement.
