description: 22. März 2019 wurde das „Gesetz zur Verbesserung der Information über einen Schwangerschaftsabbruch“ vom Deutschen Bundestag beschlossen. Dieser Beitrag zeigt anhand der Betrachtung parlamentarischer Debatten zur Änderung des §219a StGB unter Berücksichtigung von historischen Kontinuitäten auf, wie staatliche Macht über gebärfähige Personen ausgeübt wird. Das Vorhaben wird als diskursanalytisch inspirierte Inhaltsanalyse mit machtkritischem und feministischem Anspruch bezeichnet und analysiert den parlamentarischen Diskursstrang anhand von Protokollen der Beratungen der Gesetzentwürfe im Bundestag und der Sitzungen im zuständigen Ausschuss für Recht und Verbraucherschutz. Auf Basis einer feministischen Perspektive und einem Foucaultschen Machtbegriff wird untersucht, wie um Deutungsmacht über Schwangerschaftsabbrüche gerungen wird. Anhand zwei zentraler Thesen wird aufgezeigt, dass im Diskurs Schwangeren durch bestimmte Argumentationslogiken seitens Sprecher*innen eine Mutterrolle zugeschrieben und gleichzeitig die Selbstbestimmung Schwangerer dem staatlichen Schutz des Fötus als ‚ungeborenes Leben‘ untergeordnet wird. Darüber hinaus wird herausgearbeitet, dass angesichts der paradoxen Gleichzeitigkeit von suggerierter Selbstbestimmung und staatlicher Kontrolle biopolitische Regulierungsmechanismen der generativen Reproduktion sichtbar werden. Letztlich kann so am Beispiel der Debatten aufgezeigt werden, wie gebärfähige Personen zum Gegenstand moderner patriarchaler Machtverhältnisse werden.

description: We perform a theoretical analysis of atomic four-wave mixing via a collision of two Bose-Einstein condensates of metastable helium atoms, and compare the results to a recent experiment. We calculate atom-atom pair correlations within the scattering halo produced spontaneously during the collision. We also examine the expected relative number squeezing of atoms on the sphere. The analysis includes first-principles quantum simulations using the positive P-representation method. We develop a unified description of the experimental and simulation results.
Understanding the Behavioral Responses Corresponding with the Emotions Guilt and Shame

Subjects: subject: 170202 Decision Making
subject: FOS: Psychology

description: Despite the fact that the moral emotions guilt and shame seem similar, research has shown that there are important differences between them. Guilt produces negative feelings about an external event, such as one’s actions, whereas shame produces negative internal feelings about oneself (Dearing & Tangney, 2003). This distinction has potentially important behavioral consequences, yet little research has tested how the two emotions influence real behavior. This project addresses this gap by investigating the influences of shame and guilt on behavior of real consequence. Results will give greater insight into the nuances differentiating guilt from shame and the practical consequences of the emotions related to interpersonal decision making.

description: This work is an ongoing effort of curating thousands of chemical compounds captured as emissions of headspace volatiles from one of the world's most aggressive plant invasive species, namely Lantana camara. Over the past five decades, several groups have identified the composition profile of BVoCs produced by L.camara under varying conditions and contexts. We have performed first hand chemical profiling of Lantana camara foliar emissions from invasive populations in New Delhi, India, using a combination of steam distillation and Comprehensive GC. The data so obtained have been compared with existing composition profiles of the same species from native and near native habitats available in published records, with as little variation as possible in sample collection and profiling methods. The biggest challenge in this attempt has been to create a platform where multiple profiles of the same species can be curated sufficiently to bring diverse datasets on to a common comparable platform. We have used NIST libraries to re-assess and curate chemicals composition profiles and find a strong signature for differences in both quantity and quality of emissions from native and invaded habitats, providing indirect but strong evidence for the Novel Weapons Hypothesis of Invasive species evolution and success.

description: We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) image at 8 μm from the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire project, which reveals an intriguing IR shell just surrounding the large radio shell. We analyze the 21 cm H I absorption spectra and 13CO emission spectra toward PWN G54.1+0.3 and bright sources on both radio and IR shells. Continuous H I absorption up to the tangent point and absence of negative H I absorption features imply that PWN G54.1+0.3 has a distance beyond the tangent point but within the solar circle, i.e., 4.5-9 kpc. G54.1+0.3 is likely at a distance of 6.2 kpc due to the morphological association of the PWN with a CO molecular cloud at a velocity of 53 km s–1, as revealed by high-resolution 13CO images. Based on the H I absorption spectrum and recombination line velocity (40 km s–1) of the bright H II region G54.09–0.06, which is on the IR shell, the IR shell is likely located at a distance of 7.3 kpc, which is also the distance of the associated large-scale radio shell. At this distance, the radio shell has a radius of ~30 pc. The radio shell may be thermal and lack IR emission due to dust destruction, or it may be nonthermal and part of a newly found old supernova remnant. In either case, it is located at a distance different from PWN G54.1+0.3.

description: The Kawahara and modified Kawahara equations are fifth-order KdV type equations and have been derived to model many physical phenomena such as gravity-capillary waves and magneto-sound propagation in plasmas. This paper establishes the local well-posedness of the initial-value problem for Kawahara equation in $H^s({\mathbf R})$ with $s>-\frac74$ and the local well-posedness for the modified Kawahara equation in $H^s({\mathbf R})$ with $s\ge-\frac14$. To prove these results, we derive a fundamental estimate on dyadic blocks for the Kawahara equation through the $[k; Z]$ multiplier norm method of Tao \cite{Tao2001} and use this to obtain new bilinear and trilinear estimates in suitable Bourgain spaces.

Through a series of in-class observations and interviews with the educators, it seeks to advance insight into the frequency and value of communication between the educators, parents and other involved caregivers of the children. The information gained will be utilized to inform the development of processes and technology in the future, which can assist these caregivers in their ability to provide for the children.
Heavy quark structure functions from unifying the color dipole picture and double asymptotic scaling approaches

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present an analysis of the heavy quark structure functions from the $k_{t}$ factorization scheme, using unifying the color dipole picture and double asymptotic scaling approaches at small $x$. The gluon distribution is obtained from the Golec-Biernat-W$\ddot{\mathrm{u}}$sthoff (GBW) and Bartels, Golec-Biernat and Kowalski (BGK )models. The main elements are based on the color dipole picture (CDP) and the generalized double asymptotic scaling (DAS) approach for usual parton distribution functions (PDFs). The comparisons with the HERA data are made and predictions for the proposed LHeC and FCC-he colliders are also provided in a wide range of the transverse separation $r$. In particular, the ratio $R^{h}=F_{L}^{h}/F_{2}^{h}, h=c,b,t$ is well described by the dipole models and is sensitive to the collider energies from HERA until FCC-he. We derive correlated bounds on the ratio $F^{c}_{2}/F_{2}$ and $F^{b}_{2}/F_{2}$ and compared them with the BGK and IP-sat models. The uncertainties are due to the renormalization and factorization scales at large and low $r$ values. The Sudakov form factor into the heavy quark structure functions is incorporated and the results are considered, which are dependent on the hard scale in a wide range of the transverse separation $r$.
Unconscious Origins of the Spreading Effect

description: After choosing, people exhibit a spreading of alternatives whereby the chosen alternative is rated more positively and the rejected alternative is rated more negatively than they were previously rated. People are assumed to reassess their attitudes to reduce cognitive dissonance—discomfort that stems from considering the negative features of the chosen alternative and the positive features of the rejected alternative. Whereas most dissonance research has examined its possible conscious origins, surprisingly little research has examined the possibility that dissonance is due to unconscious processes. We tested whether the act of rejecting an alternative might engender response inhibition toward the stimulus, which would suggest the spreading of alternatives is due to an unconscious process. Research participants made choices between equally liked stimuli and completing a go/no-go reaction time task with the chosen and rejected stimuli before re-rating those stimuli. Although we did not find response inhibition for the rejected alternatives or response facilitation for the chosen alternatives, we did find evidence that the presence of the chosen and rejected stimuli influenced the ease with which the go/no-go signals were processed by the participants, supporting the assumption that an automatic process may play some role in the spreading of alternatives.

This level of precision is required in the search for 1 Earth mass planets in the Habitable Zones of Sun-like stars by the Radial Velocity (RV) method, where the maximum semi-amplitude is about 9 cm/s. We have developed BCPy to be used in the pipeline for the next generation Doppler Spectrometers - Habitable-zone Planet Finder (HPF) and NEID. In this work, we also develop an automated leap second management routine to improve upon the one available in Astropy. It checks for and downloads a new leap second file before converting from the UT time scale to TDB.

description: This work adopts an information theoretic framework for the design of collusion-resistant coding/decoding schemes for digital fingerprinting. More specifically, the minimum distance decision rule is used to identify 1 out of t pirates. Achievable rates, under this detection rule, are characterized in two distinct scenarios. First, we consider the averaging attack where a random coding argument is used to show that the rate 1/2 is achievable with t=2 pirates. Our study is then extended to the general case of arbitrary $t$ highlighting the underlying complexity-performance tradeoff. Overall, these results establish the significant performance gains offered by minimum distance decoding as compared to other approaches based on orthogonal codes and correlation detectors. In the second scenario, we characterize the achievable rates, with minimum distance decoding, under any collusion attack that satisfies the marking assumption. For t=2 pirates, we show that the rate $1-H(0.25)\approx 0.188$ is achievable using an ensemble of random linear codes. For $t\geq 3$, the existence of a non-resolvable collusion attack, with minimum distance decoding, for any non-zero rate is established. Inspired by our theoretical analysis, we then construct coding/decoding schemes for fingerprinting based on the celebrated Belief-Propagation framework. Using an explicit repeat-accumulate code, we obtain a vanishingly small probability of misidentification at rate 1/3 under averaging attack with t=2. For collusion attacks which satisfy the marking assumption, we use a more sophisticated accumulate repeat accumulate code to obtain a vanishingly small misidentification probability at rate 1/9 with t=2. These results represent a marked improvement over the best available designs in the literature.

description: We propose a threshold detector for Lévy distributed fluctuations based on a Josephson junction. The Lévy noise current added to a linearly ramped bias current results in clear changes in the distribution of switching currents out of the zero-voltage state of the junction. We observe that the analysis of the cumulative distribution function of the switching currents supplies information on both the characteristics shape parameter $α$ of the Lévy statistics and the intensity of the fluctuations. Moreover, we discuss a theoretical model which allows to extract characteristic features of the Lévy fluctuations from a measured distribution of switching currents. In view of this results, this system can effectively find an application as a detector for a Lévy signal embedded in a noisy background.

Prediction for Nonabelian Fine Structure Constants from Multicriticality

Publisher: name: arXiv
Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In developing a model for predicting the nonabelian gauge coupling constants we argue for the phenomenological validity of a ``principle of multiple point criticality''. This is supplemented with the assumption of an ``(grand) anti-unified'' gauge group $SMG^{N_{gen.}}\sim U(1)^{N_{gen.}}\times SU(2)^{N_{gen.}}\times SU(3)^{N_{gen.}}$ that, at the Planck scale, breaks down to the diagonal subgroup. Here $N_{gen}$ is the number of generations which is assumed to be 3. According to this ``multiple point criticality principle'', the Planck scale experimental couplings correspond to multiple point couplings of the bulk phase transition of a lattice gauge theory (with gauge group $SMG^{N_{gen.}}$). Predictions from this principle agree with running nonabelian couplings (after an extrapolation to the Planck scale using the assumption of a ``desert'') to an accuracy of 7\%. As an explanation for the existence of the multiple point, a speculative model using a glassy lattice gauge theory is presented.

description: The current international political system places a heavy focus on one of the most pressing issues of the current era: extremism in the form of terrorism and insurgencies. Extremism is a word that can be applied to a vast variety of actors and strategies, defined by Manus Midlarsky as “the will to power by a social movement in the service of a political program typically at variance with that supported by existing state authorities, and for which individual liberties are to be curtailed in the name of collective goals, including the mass murder of those who would actually or potentially disagree with that program.”1 Terrorist organizations and insurgencies are two physical manifestations of extremism that allow the concept to take control of a region, often resulting in widespread violence. While the concept of extremism is by no means new, its ability to cause widespread destruction through insurgencies and terrorist organizations using modern technology and strategies certainly is, leading extremism to be a large source of concern even in countries that are thousands of miles from any armed extremist conflicts. Policy has failed in the past to provide a solution with the potential to calm these fears, and in the case of the wars in Iraq and Afghanistan, seems to only strengthen the flame of extremism

description: An important aspect of solar energetic particle (SEP) events is their source populations. Elemental abundance enhancements of impulsive SEP events, originating in presumed coronal reconnection episodes, can be fitted to steep power laws of A/Q, where A and Q are the atomic mass and ionic charge. Since thermal electron energies are enhanced and nonthermal electron distributions arise in the reconnection process, we might expect that ionic charge states Q would be increased through ionization interactions with those electron populations during the acceleration process. The temperature estimated from the SEPs corresponds to the charge state during the acceleration process, while the actual charge state measured in situ may be modified as the SEPs pass through the corona. We examine whether the temperature estimation from the A/Q would differ with various kappa values in a kappa function representing high-energy tail deviating from a Maxwellian velocity distribution. We find that the differences in the A/Q between a Maxwellian and an extreme kappa distribution are about 10-30%. We fit power-law enhancement of element abundances as a function of their A/Q with various kappa values. Then, we find that the derived source region temperature is not significantly affected by whether or not the electron velocity distribution deviates from a Maxwellian, i.e., thermal, distribution. Assuming that electrons are heated in the acceleration region, the agreement of the SEP charge state during acceleration with typical active region temperatures suggests that SEPs are accelerated and leave the acceleration region in a shorter time than the ionization time scale.

Trouble with the Curve: Identifying Clusters of MLB Pitchers using Improved Pitch Classification Techniques

subject: FOS: Mathematics

description: The PITCHf/x database, which records the location, velocity, and trajectory of every pitch thrown in Major League Baseball (MLB), has allowed the statistical analysis of MLB to ourish since its introduction in late 2006. Using PITCHf/x, pitches have been classified by hand, requiring considerable effort, or using neu- ral network clustering and classification, which is often difficult to interpret. We use model-based clustering with a multivariate Gaussian mixture model and an adjusted Bayesian Information Criterion to determine the number of different clusters. We verify these results via cross validation, validation by prediction strength, and through visual inspection. Furthermore, we use our method to cluster pitchers into groups with similar characteristics via k-means clustering and the Fisher-wise criterion. Our method builds a strong foundation towards addressing many open MLB research questions, including preventing pitcher in- jury.
Minimizing emissions from grid-based hydrogen production in the United States
Creators: name: Ricks, Wilson
name: Xu, Qingyu

Publisher: name: Zenodo
Year: 2022

description: Low-carbon hydrogen could be an important component of a net-zero carbon economy, helping to mitigate emissions in a number of hard-to-abate sectors. The United States recently introduced an escalating production tax credit (PTC) to incentivize production of hydrogen meeting increasingly stringent embodied emissions thresholds. Hydrogen produced via electrolysis can qualify for the full subsidy under current federal accounting standards if the input electricity is generated by carbon-free resources, but may fail to do so if emitting resources are present in the generation mix. While use of behind-the-meter carbon-free electricity inputs can guarantee compliance with this standard, the PTC could also be structured to allow producers using grid-supplied electricity to qualify subject to certain clean energy procurement requirements. Herein we use electricity system capacity expansion modeling to quantitatively assess the impact of grid-connected electrolysis on the evolution of the power sector in the western United States through 2030 under multiple possible implementations of the clean hydrogen PTC. We find that subsidized grid-connected hydrogen production has the potential to induce additional emissions at effective rates worse than those of conventional, fossil-based hydrogen production pathways. Emissions can be minimized by requiring grid-based hydrogen producers to match 100% of their electricity consumption on an hourly basis with physically deliverable, ‘additional’ clean generation, which ensures effective emissions rates equivalent to electrolysis exclusively supplied by behind-the-meter carbon-free generation. While these requirements cannot eliminate indirect emissions caused by competition for limited clean resources, which we find to be a persistent result of large hydrogen production subsidies, they consistently outperform alternative approaches relying on relaxed time matching or marginal emissions accounting. Added hydrogen production costs from enforcing an hourly matching requirement rather than no requirements are less than $1/kg, and can be near zero if clean, firm electricity resources are available for procurement. This is the accepted manuscript for 'Minimizing emissions from grid-based hydrogen production in the United States' by Ricks et al., published in Environmental Research Letters on January 6, 2023.

description: In this paper, we discuss the multi-Higgs doublet models, that could be effectively induced by the extended Standard Model (SM). In particular, we focus on the phenomenology in the supersymmetric model with left-right (LR) symmetry, where the down-type and the up-type Yukawa couplings are unified and the Yukawa coupling matrices are expected to be hermitian. In this model, several Higgs doublets are introduced to realize the realistic fermion mass matrices, and the heavy Higgs doublets have flavor changing couplings with quarks and leptons. The LR symmetry is assumed to break down at high energy to realize the Type-I seesaw mechanism. The supersymmetry breaking scale is expected to be around 100 TeV to achieve the 125 GeV Higgs. In such a setup, the flavor-dependent interaction of the Higgs fields becomes sizable, so that we especially discuss the flavor physics induced by the heavy Higgs fields in our work. Our prediction depends on the structure of neutrinos, e.g., the neutrino mass ordering. We demonstrate how the flavor structure of the SM affects the flavor violating couplings. In our analysis, we mainly focus on the four-fermi interaction induced by the scalar exchanging, and we propose a simple parameterization for the coefficients. Then, we find the correlations among the flavor observables and, for instance, see that our prediction for the $μ\to 3 e$ process could be covered by the future experiment, in one case where the neutrino mass hierarchy is normal.

In addition to representing the most-distant observed filament at extreme ultraviolet wavelengths -- captured by Solar Orbiter's field of view extending to above 6 $R_{\odot}$ -- this event was also associated with the release of a fast ($\sim$2200 km$\cdot$s$^{-1}$) coronal mass ejection (CME) that was directed towards BepiColombo and Parker Solar Probe. These two probes were separated by 2$^{\circ}$ in latitude, 4$^{\circ}$ in longitude, and 0.03 au in radial distance around the time of the CME-driven shock arrival in situ. The relative proximity of the two probes to each other and to the Sun ($\sim$0.35 au) allows us to study the mesoscale structure of CMEs at Mercury's orbit for the first time. We analyse similarities and differences in the main CME-related structures measured at the two locations, namely the interplanetary shock, the sheath region, and the magnetic ejecta. We find that, despite the separation between the two spacecraft being well within the typical uncertainties associated with determination of CME geometric parameters from remote-sensing observations, the two sets of in-situ measurements display some profound differences that make understanding of the overall 3D CME structure particularly challenging. Finally, we discuss our findings within the context of space weather at Mercury's distances and in terms of the need to investigate solar transients via spacecraft constellations with small separations, which has been gaining significant attention during recent years.

description: We show that high-$p_T$ $R_{AA}$ and $v_2$ are sensitive to the early expansion dynamics, and that the high-$p_T$ observables prefer delayed onset of energy loss and transverse expansion. To calculate high-$p_T$ $R_{AA}$ and $v_2$, we employ our newly developed DREENA-A framework, which combines state-of-the-art dynamical energy loss model with 3+1-dimensional hydrodynamical simulations. The model applies to both light and heavy flavor, and we predict a larger sensitivity of heavy flavor observables to the onset of transverse expansion. This presents the first time when bulk QGP behavior has been constrained by high-$p_\perp$ observables and related theory, i.e., by so-called QGP tomography.

description: We study a relativistic collisionless electron-positron shock propagating into an unmagnetized ambient medium using 2D particle-in-cell simulations of unprecedented duration and size. The shock generates intermittent magnetic structures of increasingly larger size as the simulation progresses. Toward the end of our simulation, at around 26,000 plasma times, the magnetic coherence scale approaches $λ\sim 100$ plasma skin depths, both ahead and behind the shock front. We anticipate a continued growth of $λ$ beyond the time span of our simulation, as long as the shock accelerates particles to increasingly higher energies. The post-shock field is concentrated in localized patches, which maintain a local magnetic energy fraction $\varepsilon_B\sim 0.1$. Particles randomly sampling the downstream fields spend most of their time in low field regions ($\varepsilon_B\ll 0.1$), but emit a large fraction of the synchrotron power in the localized patches with strong fields ($\varepsilon_B\sim 0.1$). Our results have important implications for models of gamma-ray burst afterglows.

Minimizing emissions from grid-based hydrogen production in the United States

description: Low-carbon hydrogen could be an important component of a net-zero carbon economy, helping to mitigate emissions in a number of hard-to-abate sectors. The United States recently introduced an escalating production tax credit (PTC) to incentivize production of hydrogen meeting increasingly stringent embodied emissions thresholds. Hydrogen produced via electrolysis can qualify for the full subsidy under current federal accounting standards if the input electricity is generated by carbon-free resources, but may fail to do so if emitting resources are present in the generation mix. While use of behind-the-meter carbon-free electricity inputs can guarantee compliance with this standard, the PTC could also be structured to allow producers using grid-supplied electricity to qualify subject to certain clean energy procurement requirements. Herein we use electricity system capacity expansion modeling to quantitatively assess the impact of grid-connected electrolysis on the evolution of the power sector in the western United States through 2030 under multiple possible implementations of the clean hydrogen PTC. We find that subsidized grid-connected hydrogen production has the potential to induce additional emissions at effective rates worse than those of conventional, fossil-based hydrogen production pathways. Emissions can be minimized by requiring grid-based hydrogen producers to match 100% of their electricity consumption on an hourly basis with physically deliverable, ‘additional’ clean generation, which ensures effective emissions rates equivalent to electrolysis exclusively supplied by behind-the-meter carbon-free generation. While these requirements cannot eliminate indirect emissions caused by competition for limited clean resources, which we find to be a persistent result of large hydrogen production subsidies, they consistently outperform alternative approaches relying on relaxed time matching or marginal emissions accounting. Added hydrogen production costs from enforcing an hourly matching requirement rather than no requirements are less than $1/kg, and can be near zero if clean, firm electricity resources are  available for procurement.

description: We study nonequilibrium dephasing in an electronic Mach-Zehnder interferometer. We demonstrate that the shot noise at the beam splitter of the interferometer generates an ensemble of nonequilibrium electron density configurations and that electron interactions induce configuration-specific phase shifts of an interfering electron. The resulting dephasing exhibits two characteristic features, a lobe pattern in the visibility and phase jumps of $π$, in good agreement with experimental data.

description: We present results for the isovector axial, induced pseudoscalar, electric, and magnetic form factors of the nucleon. The calculations were done using $2+1+1$-flavor HISQ ensembles generated by the MILC collaboration with lattice spacings $a \approx$ 0.12, 0.09, 0.06$\mathrm{fm}$ and pion masses $M_π\approx$ 310, 220, 130$\mathrm{MeV}$. Excited-states contamination is controlled by using four-state fits to two-point correlators and by comparing two- versus three-states in three-point correlators. The $Q^2$ behavior is analyzed using the model independent z-expansion and the dipole ansatz. Final results for the charge radii and magnetic moment are obtained using a simultaneous fit in $M_π$, lattice spacing $a$ and finite volume.

description: We propose and perform a joint analysis of the two different mass estimates of galaxy clusters, namely the hydrostatic and caustic techniques. Firstly, we show comprehensively that the mass bias between these two techniques can be possibly alleviated when cluster-specific assumptions constrained using the hydrostatic technique are utilized within the caustic technique. While at face value this demotes the caustic technique from a completely independent method, this allows one to further tighten the constraints on the cluster mass and subsequently, allow us to test modifications to gravity. Implementing the aforementioned formalism for two well-observed massive galaxy clusters, A2029 and A2142, we highlight the proof of concept. In the current implementation, we use this method to constrain the Chameleon screening and Vainshtein screening. As anticipated, we show that the joint analysis can help improve the constraints on these modified gravity scenarios.

description: This paper proposes a classification framework aimed at identifying correlations between job ad requirements and transversal skill sets, with a focus on predicting the necessary skills for individual job descriptions using a deep learning model. The approach involves data collection, preprocessing, and labeling using ESCO (European Skills, Competences, and Occupations) taxonomy. Hierarchical classification and multi-label strategies are used for skill identification, while augmentation techniques address data imbalance, enhancing model robustness. A comparison between results obtained with English-specific and multi-language sentence embedding models reveals close accuracy. The experimental case studies detail neural network configurations, hyperparameters, and cross-validation results, highlighting the efficacy of the hierarchical approach and the suitability of the multi-language model for the diverse European job market. Thus, a new approach is proposed for the hierarchical classification of transversal skills from job ads.
