Roland Pauler, Karl der skrupellose Große: Das Ergebnis von zwei Jahrhunderten Fehlinterpretationen im Bann des Nationalismus. Göttingen: Cuvillier Verlag, 2021, 183 S.
Authors: Classen Albrecht
Published: April 2022

Nur mit Zögern habe ich die Rezension dieses Buches übernommen, denn auf weite Strecken handelt es sich einerseits um das Bemühen des Autors, sich mit ungeheuer Vehemenz gegen die Historikerzunft in Deutschland aufzulehnen und sie in ihre Schranken zu verweisen, was die
eigentlichen historischen Fakten angeht, andererseits eine Studie vorzulegen, die die Geschichte der Mediävistik im 19. und frühen 20. Jahrhundert untersucht. Beides dürfte jedenfalls für unsere Zeitschrift unangebracht sein.

Abstract: Erneut ist eine Studie zu Gottfrieds von Strassburg Tristan erschienen, was angesichts der Komplexität und Provokation dieses fragmentarischen Versromans nicht überrascht. Es handelt sich aber weniger um eine Monographie als vielmehr um eine Sammlung
von fünf Aufsätzen, die ihren Ursprung in Bulangs Antrittsvorlesung an der Heidelberger Universität 2014 besitzen. Damals hatte er sich speziell darum bemüht, die metaphorische Relevanz von Gold im Tristan herauszukristallisieren; seitdem sind eine Reihe von neuen
Aspekten dazugekommen, was ihn dazu ermunterte, diese fünf separaten Studien miteinander gebunden zu veröffentlichen.
Antibody-drug conjugates: beyond current approvals and potential future strategies
Authors: Menon Siddharth , Parakh Sagun , Scott Andrew M. , Gan Hui K.
Published: April 2022

The recent approvals for antibody-drug conjugates (ADCs) in multiple malignancies in recent years have fuelled the ongoing development of this class of drugs. These novel agents combine the benefits of high specific targeting of oncogenic cell surface antigens with the additional cell kill from high potency cytotoxic payloads, thus achieving wider therapeutic windows. This review will summarise the clinical activity of ADCs in tumour types not covered elsewhere in this issue, such as gastrointestinal (GI) and genitourinary (GU) cancers and glioblastoma (GBM). In addition to the ongoing clinical testing of existing ADCs, there is substantial preclinical and early phase testing of newer ADCs or ADC incorporating strategies. This review will provide selected insights into such future development, focusing on the development of novel ADCs against new antigen targets in the tumour microenvironment (TME) and combination of ADCs with immuno-oncology (IO) agents.

Published: April 2022

Creative employees are treasured assets for organizations to remain competitive in the market. However, we still know little about how to encourage employee creativity in an organization. Taking a motivational perspective, this study aims to examine the direct relationship between job crafting and creativity and the indirect relationship through sense of calling. We collected information from 359 Indonesian tour guides, then we analyzed it using WarpPLS 4. The results of the study revealed that job crafting was positively related to employee creativity. In addition, it shows that the sense of calling sense of calling is able to become a connecting bridge in efforts to increase employee creativity.

Conditions and possibilities of using Baltic amber heritage in the development of territorial cooperation
Authors: Studzieniecki Tomasz
Published: April 2022

Baltic amber, also referred to as the “gold of the Baltic Sea”, is one of the most valuable fossil resins in the world. Due to its valuable properties, it has been the subject of international cooperation and exchange since ancient times. Then numerous trade routes were laid, which gradually turned into tourist attractions. Nowadays, amber contributes to the development of cities and regions where it is mined and processed. This gives them a competitive advantage, creates a positive image and stimulates territorial cooperation. The essence of this cooperation lies in the use of the socio-economic capital of interested parties connected by common interests. Representatives of the world of science, business and non-governmental organizations participate in this cooperation.
An example of the effective use of amber and its heritage in activities that stimulate territorial development is Pomeranian Voivodeship with its capital in Gdańsk. The article analyses the activities in this area carried out since 1996 by two non-governmental organizations: the Agencja Rozwoju Regionalnego Foundation (Agency for Regional Development) and the association Academia Europa Nostra. The study was conducted using of secondary sources, including the resources of both organizations and the knowledge of the author, the initiator and coordinator of numerous initiatives related to the heritage of amber.
Organizational mechanism of cross-border tourism clusters creation
Authors: Silicheva Natalia
Published: April 2022

The article provides a detailed analysis of the theory and practice of organizing cross-border tourism clusters. Tourism is a significant economic priority for the economic activity of states. It is the study of the cluster model for the development of tourism activities that triggers the factors of competitiveness. This is primarily due to the generation of a synergistic effect, not only for cluster enterprises, but also for the country as a whole. The essence of cross-border cooperation in the tourism industry is determined, general global trends in the development of tourism clusters are given. An analysis was made of possible organizational forms of cluster structures, which should, first of all, comply with the legislative framework of the countries participating in the transboundary cluster. The organizational mechanism for the formation of cross-border tourism clusters is generalized. The hypothesis is substantiated that the creation of tourist clusters makes economic sense associated with the coordination and extraction of additional benefits within the distribution network from services in the destination. As the tourism sector develops, the cluster model is increasingly used as a source of adaptive management decisions by individual economic entities. It is proposed to activate the clustering process in the states in order to create innovative cross-border tourism clusters.
Seasonal population of Pskov region: quantitative and qualitative assessment
Authors: Krasnov Anton
Published: April 2022

The seasonal population is an extremely important component of the pulsating settlement systems, especially in such sparsely populated areas as the Non-Chernozem region. Estimating of the size of this population is an urgent and difficult task due to objective difficulties in taking it into account. In this paper there was made an attempt of quantitatively and qualitatively estimating of the seasonal population of the Pskov region (dacha residents) and analyzing of their spatial distribution. The aim was to estimate and spatially analyze the summer (dacha) population of the Pskov region based on the data of the Russian agricultural census and expert assessments of local authorities based on the results of a survey of administrations of rural settlements. The authors used official and expert data, based on the synthesis of which the study was conducted. The scientific novelty of the work lies in the fact that for the first time a quantitative assessment was carried out and the key factors influencing the seasonal population were identified. As a result, spatial patterns of seasonal population distribution were revealed and its main areas were established based on the analysis of the main factors of attractiveness. Also, there given a calculation, showing the quantitative extent of the distribution of summer residents, so, according to the results of the study, the population of the rural areas of the region at its peak can double.

AN EFFECTIVE AND SIMPLE SCHEME FOR SOLVING NONLINEAR FREDHOLM INTEGRAL EQUATIONS
Authors: Shahsavaran Ahmad , Fotros Forough
Published: April 2022

In this paper, a simple scheme is constructed for finding approximate solution of the nonlinear Fredholm integral equation of the second kind. To this end, the Lagrange interpolation polynomials together with the Gauss-Legendre quadrature rule are used to transform the source problem to a system of nonlinear algebraic equations. Afterwards, the resulting system can be solved by the Newton method. The basic idea is to choose the Lagrange interpolation points to be the same as the points for the Gauss-Legendre integration. This facilitates the evaluation of the integral part of the equation. We prove that the approximate solution converges uniformly to the exact solution. Also, stability of the approximate solution is investigated. The advantages of the method are simplicity, fastness and accuracy which enhance its applicability in practical situations. Finally, we provide some test examples.

NUMERICAL SOLUTIONS FOR 2D UNSTEADY LAPLACE-TYPE PROBLEMS OF ANISOTROPIC FUNCTIONALLY GRADED MATERIALS
Authors: Azis Mohammad Ivan
Published: April 2022

The time-dependent Laplace-type equation of variable coefficients for anisotropic inhomogeneous media is discussed in this paper. Numerical solutions to problems which are governed by the equation are sought by using a combined Laplace transform and boundary element method. The variable coefficients equation is transformed to a constant coefficients equation. The constant coefficients equation after being Laplace transformed is then written in a boundary-only integral equation involving a time-free fundamental solution. The boundary integral equation is therefore employed to find the numerical solutions using a standard boundary element method. Finally the numerical results are inversely transformed numerically using the Stehfest formula to obtain solutions in the time variable. Some problems of anisotropic functionally graded media are considered. The results show that the combined Laplace transform and boundary element method is accurate and easy to implement.
A Pluto–Charon Sonata IV. Improved Constraints on the Dynamical Behavior and Masses of the Small Satellites
Authors: Kenyon Scott J. , Bromley Benjamin C.
Published: April 2022

We discuss a new set of ∼500 numerical n-body calculations designed to constrain the masses and bulk densities of Styx, Nix, Kerberos, and Hydra. Comparisons of different techniques for deriving the semimajor axis and eccentricity of the four satellites favor methods relying on the theory of Lee & Peale, where satellite orbits are derived in the context of the restricted three-body problem (Pluto, Charon, and one massless satellite). In each simulation, we adopt the nominal satellite masses derived in Kenyon & Bromley, multiply the mass of at least one satellite by a numerical factor f ≥ 1, and establish whether the system ejects at least one satellite on a timescale ≤4.5 Gyr. When the total system mass is large (f ≫ 1), ejections of Kerberos are more common. Systems with lower satellite masses (f ≈ 1) usually eject Styx. In these calculations, Styx often “signals” an ejection by moving to higher orbital inclination long before ejection; Kerberos rarely signals in a useful way. The n-body results suggest that Styx and Kerberos are more likely to have bulk densities comparable with water ice, ρ
SK ≲ 2 g cm−3, than with rock. A strong upper limit on the total system mass, M
SNKH ≲ 9.5 × 1019 g, also places robust constraints on the average bulk density of the four satellites, ρ
SNKH ≲ 1.4 g cm−3. These limits support models where the satellites grow out of icy material ejected during a major impact on Pluto or Charon.
Relativistic Description of Dense Matter Equation of State and Compatibility with Neutron Star Observables: A Bayesian Approach
Authors: Malik Tuhin , Ferreira Márcio , Agrawal B. K. , Providência Constança
Published: April 2022

The general behavior of the nuclear equation of state (EOS), relevant for the description of neutron stars (NSs), is studied within a Bayesian approach applied to a set of models based on a density-dependent relativistic mean-field description of nuclear matter. The EOS is subjected to a minimal number of constraints based on nuclear saturation properties and the low-density pure neutron matter EOS obtained from a precise next-to-next-to-next-to-leading order (N3LO) calculation in chiral effective field theory (χEFT). The posterior distributions of the model parameters obtained under these minimal constraints are employed to construct the distributions of various nuclear matter properties and NS properties such as radii, tidal deformabilities, central energy densities, speeds of sound, etc. We found that a 90% confidence interval for the allowed NS mass–radius relationship and tidal deformabilities is compatible with GW170817 and recent Neutron star Interior Composition ExploreR observations, without invoking the exotic degrees of freedom. A central speed of sound of the order of

Massive Young Stellar Objects in the Galactic Center. II. Seeing Through the Ice-rich Envelopes

Published: April 2022

To study the demographics of interstellar ices in the Central Molecular Zone (CMZ) of the Milky Way, we obtain near-infrared spectra of 109 red point sources using NASA IRTF/SpeX at Maunakea. We select the sample from near- and mid-infrared photometry, including 12 objects in the previous paper of this series, to ensure that these sources trace a large amount of absorption through clouds in each line of sight. We find that most of the sample (100 objects) show CO band-head absorption at 2.3 μm, tagging them as red (super-) giants. Despite the photospheric signature, however, a fraction of the sample with L-band spectra (9/82 = 0.11) exhibit large H2O ice column densities (N > 2 × 1018 cm−2), and six of them also reveal CH3OH ice absorption. As one of such objects is identified as a young stellar object (YSO) in our previous work, these ice-rich sight lines are likely associated with background stars in projection to an extended envelope of a YSO or a dense cloud core. The low frequency of such objects in the early stage of stellar evolution implies a low star-formation rate (≲0.02 M
⊙ yr−1), reinforcing the previous claim on the suppressed star-formation activity in the CMZ. Our data also indicate that the strong “shoulder” CO2 ice absorption at 15.4 μm observed in YSO candidates in the previous paper arises from CH3OH-rich ice grains having a large CO2 concentration [N(CO2)/N(CH3OH) ≈ 1/3].

Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust. In this work, we measure a representative sample of near-infrared (NIR; 0.8–5.5 μm) spectroscopic extinction curves for the first time, enabling us to investigate the extinction at wavelengths where it is usually only measured in broad photometric bands. We use IRTF/SpeX spectra of a sample of reddened and comparison stars to measure 15 extinction curves with the pair method. Our sample spans A(V) values from 0.78 to 5.65 and R(V) values from 2.43 to 5.33. We confirm that the NIR extinction curves are well fit by a power law, with indices and amplitudes differing from sight line to sight line. Our average diffuse NIR extinction curve can be represented by a single power law with index α = 1.7, but because of the sight line-to-sight line variations, the shape of any average curve will depend on the parental sample. We find that most of the variation in our sample can be linked to the ratio of total-to-selective extinction R(V), a rough measurement of the average dust grain size. Two sight lines in our sample clearly show the ice extinction feature at 3 μm, which can be fitted by a modified Drude profile. We find tentative ice detections with slightly over 3σ significance in two other sight lines. In our average diffuse extinction curve, we measure a 3σ upper limit of A(ice)/A(V) = 0.0021 for this ice feature.
Wave-optical Effects in the Microlensing of Continuous Gravitational Waves by Star Clusters
Authors: Suvorov Arthur G.
Published: April 2022

Rapidly rotating neutron stars are promising sources for existing and upcoming gravitational-wave interferometers. While relatively dim, these systems are expected to emit continuously, allowing for signal to be accumulated through persistent monitoring over year-long timescales. If, at some point during the observational window, the source comes to lie behind a dense collection of stars, transient gravitational lensing may occur. Such events, though rare, would modulate the waveform, induce phase drifts, and ultimately affect parameter inferences concerning the nuclear equation of state and/or magnetic field structure of the neutron star. Importantly, the radiation wavelength will typically exceed the Schwarzschild radius of the individual perturbers in this scenario, implying that (micro)lensing occurs in the diffractive regime, where geometric optics does not apply. In this paper, we make use of numerical tools that borrow from Picard–Lefschetz theory to efficiently evaluate the relevant Fresnel–Kirchhoff integrals for n ≳ 102 microlenses. Modulated strain profiles are constructed both in general and for particular neutron star trajectories relative to some simulated macrolenses.

We present observations of ASASSN-20hx, a nearby ambiguous nuclear transient (ANT) discovered in NGC 6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). We observed ASASSN-20hx from −30 to 275 days relative to the peak UV/optical emission using high-cadence, multiwavelength spectroscopy and photometry. From Transiting Exoplanet Survey Satellite data, we determine that the ANT began to brighten on 2020 June 22.8 with a linear rise in flux for at least the first week. ASASSN-20hx peaked in the UV/optical 30 days later on 2020 July 22.8 (MJD = 59052.8) at a bolometric luminosity of L = (3.15 ± 0.04) × 1043 erg s−1. The subsequent decline is slower than any TDE observed to date and consistent with many other ANTs. Compared to an archival X-ray detection, the X-ray luminosity of ASASSN-20hx increased by an order of magnitude to L

x
∼ 1.5 × 1042 erg s−1 and then slowly declined over time. The X-ray emission is well fit by a power law with a photon index of Γ ∼ 2.3–2.6. Both the optical and near-infrared spectra of ASASSN-20hx lack emission lines, unusual for any known class of nuclear transient. While ASASSN-20hx has some characteristics seen in both tidal disruption events and active galactic nuclei, it cannot be definitively classified with current data.

High dust density in the midplane of protoplanetary disks is favorable for efficient grain growth and can allow fast formation of planetesimals and planets, before disks dissipate. Vertical settling and dust trapping in pressure maxima are two mechanisms allowing dust to concentrate in geometrically thin and high-density regions. In this work, we aim to study these mechanisms in the highly inclined protoplanetary disk SSTC2D J163131.2-242627 (Oph 163131, i ∼ 84°). We present new high-angular-resolution continuum and 12CO ALMA observations of Oph 163131. The gas emission appears significantly more extended in the vertical and radial direction compared to the dust emission, consistent with vertical settling and possibly radial drift. In addition, the new continuum observations reveal two clear rings. The outer ring, located at ∼100 au, is well-resolved in the observations, allowing us to put stringent constraints on the vertical extent of millimeter dust particles. We model the disk using radiative transfer and find that the scale height of millimeter-sized grains is 0.5 au or less at 100 au from the central star. This value is about one order of magnitude smaller than the scale height of smaller micron-sized dust grains constrained by previous modeling, which implies that efficient settling of the large grains is occurring in the disk. When adopting a parametric dust settling prescription, we find that the observations are consistent with a turbulent viscosity coefficient of about α ≲ 10−5 at 100 au. Finally, we find that the thin dust scale height measured in Oph 163131 is favorable for planetary growth by pebble accretion: a 10 M
E planet may grow within less than 10 Myr, even in orbits exceeding 50 au.

Stellar rotation is a complex function of mass, metallicity, and age and can be altered by binarity. To understand the importance of these parameters in main-sequence stars, we have assembled a sample of observations that spans a range of these parameters using a combination of observations from The Transiting Exoplanet Survey Satellite (TESS) and the Kepler Space Telescope. We find that while we can measure rotation periods and identify other classes of stellar variability (e.g., pulsations) from TESS light curves, instrument systematics prevent the detection of rotation signals longer than the TESS orbital period of 13.7 days. Due to this detection limit, we also use rotation periods constrained using rotational velocities measured by the APOGEE spectroscopic survey and radii estimated using the Gaia mission for both TESS and Kepler stars. From these rotation periods, we (1) find we can track rotational evolution along discrete mass tracks as a function of stellar age, (2) find we are unable to recover trends between rotation and metallicity that were observed by previous studies, and (3) note that our sample reveals that wide binary companions do not affect rotation, while close binary companions cause stars to exhibit more rapid rotation than single stars.

MeV gamma-rays provide a unique window for the direct measurement of line emissions from radioisotopes, but observations have made little significant progress since COMPTEL on board the Compton Gamma-ray Observatory (CGRO). To observe celestial objects in this band, we are developing an electron-tracking Compton camera (ETCC) that realizes both bijective imaging spectroscopy and efficient background reduction gleaned from the recoil-electron track information. The energy spectrum of the observation target can then be obtained by a simple ON–OFF method using a correctly defined point-spread function on the celestial sphere. The performance of celestial object observations was validated on the second balloon SMILE-2+ , on which an ETCC with a gaseous electron tracker was installed that had a volume of 30 × 30 × 30 cm3. Gamma-rays from the Crab Nebula were detected with a significance of 4.0σ in the energy range 0.15–2.1 MeV with a live time of 5.1 hr, as expected before launch. Additionally, the light curve clarified an enhancement of gamma-ray events generated in the Galactic center region, indicating that a significant proportion of the final remaining events are cosmic gamma-rays. Independently, the observed intensity and time variation were consistent with the prelaunch estimates except in the Galactic center region. The estimates were based on the total background of extragalactic diffuse, atmospheric, and instrumental gamma-rays after accounting for the variations in the atmospheric depth and rigidity during the level flight. The Crab results and light curve strongly support our understanding of both the detection sensitivity and the background in real observations. This work promises significant advances in MeV gamma-ray astronomy.

We obtained 93, 233, and 343 GHz continuum images with the Atacama Large Millimeter/submillimeter Array (ALMA). After self-calibration and point-source subtraction, we reach an image dynamic range of ∼85,000 at 93 GHz, ∼39,000 at 233 GHz, and ∼2500 at 343 GHz. These are currently the highest image dynamic range obtained using ALMA. We detect spatially extended millimeter emission associated with the host galaxy, cospatial with the extended emission line region (EELR) observed in the optical. The millimeter spectral energy distribution and comparison with centimeter data show that the extended emission cannot be explained by dust thermal emission or synchrotron or thermal bremsstrahlung arising from massive star formation. We interpret the extended millimeter emission as thermal bremsstrahlung from gas directly ionized by the central source. The extended flux indicates that at least ∼7% of the bolometric flux of the nuclear source was used to ionize atomic hydrogen in the host galaxy. The ionized gas is estimated to be as massive as 1010–1011
M
⊙, but the molecular gas fraction with respect to the stellar mass is consistent with other ellipticals, suggesting that direct ionization ISM by the QSO may not be sufficient to suppress star formation, or we are witnessing a short timescale before negative feedback becomes observable. The discovery of a radio counterpart to EELRs provides a new pathway to studying the QSO–host ISM interaction.

The properties of dust change during the transition from diffuse to dense clouds as a result of ice formation and dust coagulation, but much is still unclear about this transformation. We present 2–20 μm spectra of 49 field stars behind the Perseus and Serpens Molecular Clouds and establish relationships between the near-infrared continuum extinction (A
K) and the depths of the 9.7 μm silicate (τ
9.7) and 3.0 μm H2O ice (τ
3.0) absorption bands. The τ
9.7/A
K ratio varies from large, diffuse interstellar medium-like values (∼0.55), to much lower ratios (∼0.26). Above extinctions of A
K ∼ 1.2 (A
V ∼ 10; Perseus, Lupus, dense cores) and ∼2.0 (A
V ∼ 17; Serpens), the τ
9.7/A
K ratio is lowest. The τ
9.7/A
K reduction from diffuse to dense clouds is consistent with a moderate degree of grain growth (sizes up to ∼0.5 μm), increasing the near-infrared color excess (and thus A
K), but not affecting the ice and silicate band profiles. This grain growth process seems to be related to the ice column densities and dense core formation thresholds, highlighting the importance of density. After correction for Serpens foreground extinction, the H2O ice formation threshold is in the range of A
K = 0.31–0.40 (A
V = 2.6–3.4) for all clouds, and thus grain growth takes place after the ices are formed. Finally, abundant CH3OH ice (∼21% relative to H2O) is reported for 2MASSJ18285266+0028242 (Serpens), a factor of >4 larger than for the other targets.
The Identity of Rubus pekinensis Focke and R. crataegifolius Bunge (Rosaceae)
Authors: Huang Tiran , Wang Cong , Li Juntao , Liu Xuhang , Ma Lanqing , Wang Hong
Published: April 2022

A critical examination of specimens, with literature and a field survey have shown that Rubus pekinensis is conspecific with R. crataegifolius. Their morphological variations range can be defined as: leaves at the base may be ovate, suborbicular, narrowly ovate, entire, at the middle, ovate, narrowly ovate, oblong-lanceolate, palmately 3-lobed or 5-lobed and at the top, ovate, lanceolate, entire or 3-lobed; flowers solitary in the axillae or several flowers clustered at the terminal of branchlets or formed into short racemes. Therefore, we treat the former species as a synonym for the latter one.
Serge Moscovici dans sa vie. Une marginalité centrale

Serge Moscovici dans sa vie. Une marginalité centrale Entre les années 1970 et 1980 s’est opéré dans les sciences humaines un tournant éthique indiscutable. Dans le secteur de la psychologie et de l’ethnologie, et plus particulièrement dans le sillage de Serge Moscovici et Robert Jaulin, occupant une marginalité centrale au sein de l’université, s’opérait un changement de l’approche de notre rapport au politique et à la nature. Un nouvel ordre critique s’instaurait qui allait bouleverser la façon d’appréhender le monde et ses problèmes. Dans le même temps où monte le souci de l’identité et des civilisations, le colonialisme est mis en accusation et la question naturelle devient la question centrale.

Cette étude de cas aborde les sujets relatifs aux stratégies corporate et plus précisément les voies de développement (croissance horizontale et verticale) et les modes de développement (croissance organique, externe et relationnelle) d’une entreprise, souvent mobilisés en Management Stratégique de façon isolée ou alternative. La conduite stratégique de la maison du luxe Hermès traite ces différents concepts et illustre un « pattern » de développement stratégique complexe qui combine à la fois la croissance horizontale (diversification), la croissance verticale (intégration amont et aval) et l’exploitation de synergies de ressources et compétences et les synergies commerciales émergentes.
Les interactions informelles au siège de la Société Générale
Authors: Minchella Delphine , Culié Jean-Denis
Published: April 2022

L’influence positive des interactions informelles au travail sur la coopération et l’innovation a largement été démontrée, et de nombreuses recherches ont été menées pour comprendre comment celles-ci émergeaient. Cette question parait encore plus importante à l’issue de la pandémie de COVID-19, alors que les GAFA ont déjà annoncé opter pour du télétravail accru sur le long terme : de fait, les interactions informelles paraissent essentielles pour maintenir un esprit de corps. Ce cas expose la façon dont la Société Générale a tenté de les encourager lors de la construction de son Siège de La Défense bâti dans les années 1990. Nous verrons que celles-ci se sont en effet bien développées, mais pas tel que prévu.
Pourquoi certains patients n’arrivent-ils à faire leur analyse qu’en face à face ?
Authors: Diatkine Gilbert
Published: April 2022

Une psychanalyse se déroule dans les meilleures conditions lorsque le patient est allongé sur un divan et parle à l’analyste sans le voir. Cependant, ni les enfants ni certains adultes borderline ne peuvent associer librement dans cette position. Les uns et les autres ont en commun de ne pas être sortis de l’adolescence. La fin de l’adolescence se définirait alors par l’intériorisation du regard protecteur porté par les adultes sur les enfants, quelle que soit la violence des désirs inconscients de ces derniers. En l’absence de cette intériorisation du regard des adultes, le surmoi protecteur se transforme en une imago terrifiante qui paralyse le processus associatif. Avec certains patients borderline, un travail préalable en face à face est nécessaire pour décomposer cette imago et mettre les éléments dont elle est faite en réseau. Quand ces représentations ne sont pas condensées, mais agglomérées, la décomposition de l’imago met en présence des éléments clivés, séparés les uns des autres par une « position phobique centrale ». L’analyse doit alors se poursuivre en face à face. La technique de la « ponctuation », inventée par Lacan, pourrait être liée à une imago qui lui était propre, la « figure obscène et féroce du Surmoi ».
Des réverbérations de l’adulte à l’enfant. À propos d’« Églantine et ses racines »
Authors: Bydlowski Sarah
Published: April 2022

Églantine, menacée par le transfert, sature la première rencontre par un récit plus narratif qu’associatif, où ruptures et agirs s’enchaînent. Ces modalités conduisent l’analyste à privilégier des interprétations de processus, dans l’ici et maintenant, moment présent de la séance, tel qu’il s’impose avec l’enfant qui confronte l’analyste plus directement que l’adulte aux émergences de l’inconscient.
L’empathie en psychanalyse
Authors: Dufresne † Roger
Published: April 2022

L’auteur décrit la différence entre l’empathie et la sympathie, l’empathie signifiant la capacité intuitive de se mettre à la place de l’autre et de ressentir ce qu’il ressent, en conservant une grande réserve, tandis que la sympathie se réfère à un sentiment spontané de bienveillance envers l’autre, partageant son bonheur ou le soutenant dans sa souffrance. Il importe de ne pas confondre empathie et sympathie. Certains intersubjectivistes, surtout aux États-Unis, notamment ceux qui se réclament de l’école interrelationnelle et de l’école interpersonnelle, et aussi des membres de l’Association américaine et donc de l’API, qui prônent l’auto-dévoilement de l’analyste (self disclosure) confondent empathie et sympathie au point d’en faire des synonymes. L’empathie dans son sens rigoureux ne s’oppose pas à la neutralité de l’analyste, qui est avant tout réserve, silence sur soi, suspension de tout jugement afin de ne pas gêner les associations de l’analysant et de favoriser notre disponibilité dans l’écoute flottante de ses verbalisations et des émotions qu’elles induisent en nous. Notre rôle n’est pas d’appliquer nos théories, mais d’aider l’analysant dans la découverte des profondeurs de son moi.

To increase the sustainability of egg production, alternatives to soybean in poultry nutrition are intensively searched for. Black soldier fly larvae (BSFL) could have a great potential, but the comparative protein value to soybean is not well known. The main objective of this study was to facilitate this comparison by using experimental diets clearly limited in calculated supply of sulphurous amino acids and lysine. Fifty laying hens (Lohmann Brown Classic), aged 40 weeks, were fed one of five diets for 7 weeks (n=10). Two diets were based on soybean cake and oil (SS, SS-) as protein and energy sources, and three diets contained partially defatted BSFL meal and fat from two different origins (AA-, AB-, BB-). Different from SS, all other diets were designed to be deficient in methionine and lysine in relation to requirements by >20%. The realised supply with total sulphurous amino acids and lysine was indeed superior with SS even though this diet was analysed to be more deficient in methionine than the BSFL-based diets. Despite the calculated deficiency in limiting amino acids, laying performance of the hens of all groups was similar and ranged between 93 and 97%. Similarly, egg mass, daily feed intake and feed efficiency were not influenced by the BSFL-based diets. The yolks of group BB- were more intensely coloured compared to the others indicating a difference between BSFL origins. Yolks of SS-, but not of the BSFL-based diets, had lower contents of dry matter and ether extract than those of SS. Including BSFL into the diet did not influence the odour of the eggs tested in scrambled form. The results show that soybean-based feeds for laying hens may be completely replaced by BSFL-based feeds and suggest that the recommendations for amino acid supply of laying hens might need revision.
Computation of nonreciprocal dynamics in nonlinear materials
Authors: Yousefzadeh Behrooz
Published: April 2022

The reciprocity theorem in elastic materials states that the response of a linear, time-invariant system to an external load remains invariant with respect to interchanging the locations of the input and output. In the presence of nonlinear forces within a material, circumventing the reciprocity invariance requires breaking the mirror symmetry of the medium, thus allowing different wave propagation characteristics in opposite directions along the same transmission path. This work highlights the application of numerical continuation methods for exploring the steady-state nonreciprocal dynamics of nonlinear periodic materials in response to external harmonic drive. Using the archetypal example of coupled oscillators, we apply continuation methods to analyze the influence of nonlinearity and symmetry on the reciprocity invariance. We present symmetry-breaking bifurcations for systems with and without mirror symmetry, and discuss their influence on the nonreciprocal dynamics. Direct computation of the reciprocity bias allows the identification of response regimes in which nonreciprocity manifests itself as a phase shift in the output displacements. Various operating regimes, bifurcations and manifestations of nonreciprocity are identified and discussed throughout the work.
