description: A brief review is given of an adaptation of the coadjoint orbit method appropriate for study of models with infinite-dimensional symmetry groups. It is illustrated on several examples, including derivation of the WZNW action of induced $D=2\,$ $(N,0)\,$ supergravity. As a main application, we present the geometric action on a generic coadjoint orbit of the deformed group of area preserving diffeomorphisms. This action is precisely the anomalous effective WZNW action of $D=2 \,$ matter fields coupled to chiral $W_\infty$ gravity background. Similar actions are given which produce the {\em KP} hierarchy as on-shell equations of motion.

description: Adoption of pressurized irrigation systems such as drip irrigation and sprinkler irrigation influences productivity and sustainable use of water resources. Since Turkey isn't counted among water-rich countries, farmers need to use these irrigation systems. However, there are many factors associated with the adoption of agricultural innovations. This study investigates the factors influencing the adoption of pressurized irrigation technologies in Çarşamba District of Samsun Province. Participants of this study were a stratified sample of 350 farmers operated in different villages of Carşamba district. A well-structured questionnaire was administered and sought information about socioeconomic characteristicsand different farming practices applied by the participants. Data collection was completed in the May-September period of 2015. Descriptive statistics including frequencies, percentages, means and standard deviations were used to describe socioeconomic characteristics of respondents. Then farmers weredivided into two broad categories as adopters and non-adopters of pressurized irrigation systems. The independent sample t-test procedure was used to compare these two groups regarding their socioeconomic characteristics and farming practices. Results of this study showed that adopters of the pressurized irrigation system in the region use more credit for inputs, obtain a higher yield of maize per decare, and have higher level of off-farm income; however, they have smaller family size, fewer persons involved in agricultural activities, and lower number of parcels of agricultural land. Research results are expected to provide useful information in identifying the issues related to the adoption of innovations in agriculture, and in developing innovation adoption programs for rural communities.

description: We examine the thermal conductivity and bulk viscosity of a one-dimensional (1D) chain of particles with cubic-plus-quartic interparticle potentials and no on-site potentials. This system is equivalent to the FPU-alpha beta system in a subset of its parameter space. We identify three distinct frequency regimes which we call the hydrodynamic regime, the perturbative regime and the collisionless regime. In the lowest frequency regime (the hydrodynamic regime) heat is transported ballistically by long wavelength sound modes. The model that we use to describe this behaviour predicts that as the frequency goes to zero the frequency dependent bulk viscosity and the frequency dependent thermal conductivity should diverge with the same power law dependence on frequency. Thus, we can define the bulk Prandtl number as the ratio of the bulk viscosity to the thermal conductivity (with suitable prefactors to render it dimensionless). This dimensionless ratio should approach a constant value as frequency goes to zero. We use mode-coupling theory to predict the zero frequency limit. Values of the bulk Prandtl number from simulations are in agreement with these predictions over a wide range of system parameters. In the middle frequency regime, which we call the perturbative regime, heat is transported by sound modes which are damped by four-phonon processes. We call the highest frequency regime the collisionless regime since at these frequencies the observing times are much shorter than the characteristic relaxation times of phonons. The perturbative and collisionless regimes are discussed in detail in the appendices.

description: Within density-functional theory, perturbation theory~(PT) is the state-of-the-art formalism for assessing the response to homogeneous electric fields and the associated material properties, e.g., polarizabilities, dielectric constants, and Raman intensities. Here we derive a real-space formulation of PT and present an implementation within the all-electron, numeric atom-centered orbitals electronic structure code FHI-aims that allows for massively-parallel calculations. As demonstrated by extensive validation, this allows the rapid computation of accurate response properties of molecules and solids. As an application showcase, we present harmonic and anharmonic Raman spectra, the latter obtained by combining hundreds of thousands of PT calculations with \textit{ab initio} molecular dynamics. By using the PBE exchange-correlation functional with many-body van der Waals corrections, we obtain spectra in good agreement with experiment especially with respect to lineshapes for the isolated paracetamol molecule and two polymorphs of the paracetamol crystal.

description: We analytically explore the scaling properties of a general class of nested subgraphs in complex networks, which includes the $K$-core and the $K$-scaffold, among others. We name such class of subgraphs $K$-nested subgraphs due to the fact that they generate families of subgraphs such that $...S_{K+1}({\cal G})\subseteq S_K({\cal G})\subseteq S_{K-1}({\cal G})...$. Using the so-called {\em configuration model} it is shown that any family of nested subgraphs over a network with diverging second moment and finite first moment has infinite elements (i.e. lacking a percolation threshold). Moreover, for a scale-free network with the above properties, we show that any nested family of subgraphs is self-similar by looking at the degree distribution. Both numerical simulations and real data are analyzed and display good agreement with our theoretical predictions.

Instead of a ${\bf 126}$-dimensional Higgs field, a ${\bf 120}$-dimensional Higgs filed is ntroducedin addition to a ${\bf 10}$-dimensional Higgs field and plays a crucial role to reproduce the realistic charged fermion mass matrices. With contributions of ${\bf 120}$ Higgs field, the original Witten's scenario of inducing the right-handed Majorana neutrino mass through 2-loop diagrams becomes phenomenologically viable. This model inherits the nice features of the conventional renormalizable minimal SO(10) GUT model with ${\bf 10}+{\bf \overline{126}}$ Higgs fields, while supplemented with a low scale seesaw mechanism due to the 2-loop induced right-handed Majorana neutrino mass. %

description: Nowadays, induced pluripotent stem cells (iPSCs) are the most highlighted type of stem cells in research as they overcome the limitations associated with embryonic stem cells (ESCs) usage and hold a promising future for disease modeling and treatment. Generation of iPSCs is dependent on reprogramming of somatic cells by the forced introduction of reprogramming factors into the cell. To date, reprogramming procedure remains inefficient process, since a small portion of transfected cells can undergo complete reprogramming. One of the identified factors that affect the reprogramming efficiency is donor age. In this thesis, we aim to test the effect of donor age on reprogramming process using skin fibroblasts collected from PD patients who were diagnosed with early onset familial PD (A53T mutation) and late onset sporadic PD. To achieve this goal, fibroblasts were reprogrammed using Sendai virus vector to generate iPSCs. All the generated iPSCs were compared to ESCs and the commercially available iPSCs to ensure that these generated iPSCs have the same characteristic features and to confirm their ability to express pluripotent protein markers. The number of emerged colonies was used to reflect the reprogramming efficiency. In our study, we observed that A53T (2) sample showed the highest number of iPSC colonies among the other reprogrammed samples. Our results showed that the donor age had no effect on our reprogramming procedure as number of emerged iPSC colonies in sporadic PD (age 69) was similar to both control and other A53T samples (age 45 and 48, respectively) that were isolated from individuals who were similar in age with A53T (2) sample. Therefore, further transcriptomic analysis is required to identify intrinsic factor(s) that may play a role in the significantly high number of iPSC colonies observed with A53T (2) reprogramming.

description: Do creative industries have positive spillovers for the local economy in middle-income countries? While in high-income countries several studies have shown that creative industries are highly innovative and productive, positively impacting the local economy, the evidence is scarce for middle-income countries. Using employment data, we studied the agglomeration patterns of creative industries in Colombia between 2008 and 2017. We found a positive relationship between creative industries’ agglomeration and employment in non-creative services industries. However, using a shift–share instrumental variable approach, we found no significant causality of an increase in creative industries’ employment on employment growth in other industries.

description: Schemes for creation of N particle entangled Greenberger-Horne-Zeilinger (GHZ) states are important for understanding multi-particle non-classical correlations. Here, a theoretical scheme for creation of a multi-particle GHZ state implemented on a target ensemble of N, $Λ$ three-level Rydberg atoms and a single Rydberg atom as a control using Stimulated Raman Adiabatic Passage (STIRAP) is presented. We work in the Rydberg blockade regime for the ensemble atoms induced due to excitation of the control atom to a high lying Rydberg level. It is shown that using STIRAP, atoms from one ground state of the ensemble can be adiabatically transferred to the other ground state, depending on the state of the control atom with high fidelity. Measurement of the control atom in a specific basis after this conditional transfer facilitates one-step creation of a N particle GHZ state. A thorough analysis of adiabatic conditions for this scheme and the influence of radiative decay from the excited Rydberg levels is presented. We show that this scheme is immune to the decay rate of the excited level in ensemble atoms and provides a robust way of creating GHZ states.

Mapping Large, Urban Environments with GPS-Aided SLAM

description: Simultaneous Localization and Mapping (SLAM) has been an active area of research for several decades, and has become a foundation of indoor mobile robotics. However, although the scale and quality of results have improved markedly in that time period, no current technique can e ectively handle city-sized urban areas.

 The Global Positioning System (GPS) is an extraordinarily useful source of localization information. Unfortunately, the noise characteristics of the system are complex, arising from a large number of sources, some of which have large autocorrelation. Incorporation of GPS signals into SLAM algorithms requires using low-level system information and explicit models of the underlying system to make appropriate use of the information. The potential bene ts of combining GPS and SLAM include increased robustness, increased scalability, and improved accuracy of localization.

 This dissertation presents a theoretical background for GPS-SLAM fusion. The presented model balances ease of implementation with correct handling of the highly colored sources of noise in a GPS system.. This utility of the theory is explored and validated in the framework of a simulated Extended Kalman Filter driven by real-world noise.

 The model is then extended to Smoothing and Mapping (SAM), which overcomes the linearization and algorithmic complexity limitations of the EKF formulation. This GPS-SAM model is used to generate a probabilistic landmark-based urban map covering an area an order of magnitude larger than previous work.

We find that the European funds have a significantly positive effect on regional economic growth in the European Union. This result is obtained both with ordinary least squares (OLS), and with two-stage least squares (2SLS) using the presence of environmentally protected areas as an instrument. Furthermore, we find that interregional spillovers are important: a significant part of the favourable effect seems to take place in nearby regions rather than in the recipient region.

description: In most cases the content in digital repositories is accessed using a search engine. In order for this content to be found and used, it needs to be indexed and retrieved by these search engines. The ranking of the content by search engines, i.e. how high in the list of results the content is listed, also has an impact on the discoverability of this content. As it can be difficult to accurately and consistently add subject classification to content in institutional repositories, I investigated if having/not having subject metadata element in the description of these items affects its ranking by search engines, in particular Google search engine. I tested two groups of items in our institutional repository, one with and one without the subject classification in the item record. I reproduced searches for these items recorded by Google Analytics and compared the ranking of the items in the two groups. I found that items with subject metadata element ranked higher using Google search engine than items without subject metadata element.

description: $A$V$_3$Sb$_5$ ($A$ = K, Rb, Cs) is a novel kagome superconductor coexisting with the charge density wave (CDW) order. Identifying the structure of the CDW order is crucial for understanding the exotic normal state and superconductivity in this system. Here, we report $^{51}$V nuclear magnetic resonance (NMR) and $^{121/123}$Sb nuclear quadrupole resonance (NQR) studies on kagome-metal CsV$_3$Sb$_5$. Below the CDW transition temperature $T_\textrm{CDW} \sim$ 98 K, an abrupt change of spectra was observed, indicating that the transition is of the first order. By further analysing the spectra, we find that the CDW order is commensurate. And most remarkably, the obtained experimental results suggest that the charge modulation of the CDW order is of star-of-David pattern and accompanied by an additional charge modulation in bulk below $T^* \sim$ 40 K. Our results revealing the unconventional CDW order provide new insights into $A$V$_3$Sb$_5$.

description: By local measurements on party $A$ of a system $AB$ and classical communication between its two parties, one can achieve a nonlocal advantage of quantum coherence (NAQC) on party $B$. For the $l_1$ norm of coherence and the relative entropy of coherence, we generalized the framework of NAQC for two qubits and derived the criteria which capture NAQC in the $(d\times d)$-dimensional states when $d$ is a power of a prime. We also presented a new framework for formulating NAQC, and showed through explicit examples its capacity on capturing the NAQC states. Moreover, we proved that any bipartite state with NAQC is quantum entangled, thus the obtained criteria can also be used as an entanglement witness.

MeLOAR offers keyword search and location search, shows the search results with facets, maps and highlights, and shows the highlights inside the pdfs as well. The repository was from the idea stage a two purpose repository for both FAIR[3] research data from Danish universities and cultural heritage data from the Royal Library. It was from the start also an open data repository to advocate the open data agenda. An important lesson was that different users mean different user stories, both when users are national library curators vs. university researchers and when users are researchers from different disciplines with different types of data. Sometimes the solution is a dedicated front end which gives a better user experience.

Essays on the economics of education
Creators: name: Ahn, Hyunji
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation consists of three essays in the area of Economics of Education. In Chapter 2, I examine the effects of for-profit institution closures following the 2014 gainful employment policy to understand how for-profit institutions impact outcomes for potential students. I use data on degree granting Title IV postsecondary education institutions from 2010 to 2019. I combine this institution information with data on student enrollment and debt at the county level as well as educational attainment at the Public Use Microdata Area level. The closing of for-profit institutions leads to a 4.5 percent decline in the number of enrolled students in counties that experienced closings, with the largest impacts on African-American and Hispanic students. However, for-profit institutions closures have a relatively small effect on educational attainment. Furthermore, the amount of student debt declines substantially, indicating for-profit institution closures produce sustained improvements in student debts. In Chapter 3, I estimate the intergenerational effect of parents education on children’s criminal behavior using data from PSID. With the historical changes of compulsory schooling laws applied to the parent’s generation, which affects children’s crime only through parental education, I examine whether education has a causal intergenerational effect in crime reduction. From my empirical analysis, I find that an additional year of mother's education decreases the probability of her child being arrested by 9.9 percentage points, and the probability of her child being on probation by 8.3 percentage points. This result suggests that the social return of education in terms of crime reduction is substantially underestimated without taking into account this long-term effect.In Chapter 4, I study the effects of entry labor market conditions and break down the mechanism by using NLSY97. Using variation in the employment in the fields of study-cohort level, I find that cohorts experience a 5 percent increase in earnings on average during the first ten years in the labor market in response to a one-percentage-point growth in the employment level. I show that these earning gains due to the labor market condition in the year of entry can be explained by a decrease in the probability of working in an industry less matched to their skills and the switching behaviors.

description: This article sets out the first comprehensive analysis of income segregation in France across the whole urban–rural continuum. Segregation is broken down by urban areas, their size and the types of municipalities (central/suburban/exurban/rural). A significant part of the segregation is due to differences across urban areas. Moreover, regression analyses show that non-negligible levels of segregation are observed in small urban areas. Finally, disparities between exurban and central/suburban areas have increased sharply, particularly in small urban areas. These results suggest it is necessary to reconsider the view that segregation is limited to Paris, and they call for a new design of anti-segregation policies.

In the experiment, we optically excite the 6s2 1S0 -> 5d6s 3D1 transition in a region of crossed electric and magnetic fields, and observe the interference between the Stark- and weak-interaction-induced transition amplitudes, by making field reversals that change the handedness of the coordinate system. This allows us to determine the ratio of the weak-interaction-induced electric-dipole (E1) transition moment and the Stark-induced E1 moment. Our measurements, which are at the 0.5% level of accuracy for three of the four isotopes measured, allow a definitive observation of the isotopic variation of the weak-interaction effects in an atom, which is found to be consistent with the prediction of the Standard Model. In addition, our measurements provide information about an additional Z' boson.

description: In the paper, we make a comprehensive study on the hadroproduction of the $B_c (B_c^*)$ meson via the gluon-gluon fusion mechanism at the RHIC and LHC colliders. Total and differential cross sections via the proton-nucleus ($p$-N) and nucleus-nucleus (N-N) collision modes have been discussed under various collision energies. To compare with those via the proton-proton collision mode at the LHC, we observe that sizable number of $B_c (B_c^*)$-meson events can also be produced via the $p$-N and N-N collision modes at the RHIC and LHC. If assuming the spin-triplet $B^*_c$ meson directly decays to the spin-singlet $B_c$ meson with $100\%$ probability, $1.2 \times 10^5$ and $4.7 \times 10^5$ $B_c$-meson events can be produced via the $p$-Au and Au-Au collision modes at the RHIC in one operation year; $5.8 \times 10^6$ and $4.6 \times 10^6$ $B_c$-meson events can be produced via the $p$-Pb and Pb-Pb collision modes at the LHC in one operation year.

This allows a thorough investigation of modular symmetries in this type of string compactification. Such a study is explicitly carried out for the group generated by duality transformations. Thus, apart from being of phenomenological use, our couplings are also interesting from the mathematical point of view as they represent automorphic functions for a large class of discrete groups.

description: We are developing a new data repository to support data-driven developments in materials science, and it became necessary to build an open vocabulary set to describe metadata such as chemical substances, characterization methods, instruments, units, etc. There have been efforts to build a standard vocabulary or an ontology for materials science, but what should be considered as the essential concepts and how to structure them can be quite domain-specific, varying from one researcher to another, as materials science is an interdisciplinary field that encompasses chemistry, physics, and biology. To address this, we are developing a wiki-powered vocabulary management service, not only to apply aforementioned earlier efforts, but also to allow building on top of them by 'crowd-sourcing' among the researchers, thereby realizing appropriate metadata description for a highly-usable materials data repository.

description: Large computer models are ubiquitous in the earth sciences. These models often have tens or hundreds of tuneable parameters and can take thousands of core-hours to run to completion while generating terabytes of output. It is becoming common practice to develop emulators as fast approximations, or surrogates, of these models in order to explore the relationships between these inputs and outputs, understand uncertainties and generate large ensembles datasets. While the purpose of these surrogates may differ, their development is often very similar. Here we introduce ESEm: an open-source tool providing a general workflow for emulating and validating a wide variety of models and outputs. It includes efficient routines for sampling these emulators for the purpose of uncertainty quantification and model calibration. It is built on well-established, high-performance libraries to ensure robustness, extensibility and scalability. We demonstrate the flexibility of ESEm through three case-studies using ESEm to reduce parametric uncertainty in a general circulation model, explore precipitation sensitivity in a cloud resolving model and scenario uncertainty in the CMIP6 multi-model ensemble.
Search for Higgs boson decays to beyond-the-Standard-Model light bosons in four-lepton events with the ATLAS detector at $\sqrt{s}=13$ TeV

description: A search is conducted for a new beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons ($\ell =$ $e$ or $μ$). This decay is presumed to occur via an intermediate state which contains one or two on-shell, promptly decaying bosons: $H\rightarrow ZX/XX \rightarrow 4\ell$, where $X$ is a new vector boson $Z_d$ or pseudoscalar $a$ with mass between 1 and 60 GeV. The search uses $pp$ collision data collected with the ATLAS detector at the LHC with an integrated luminosity of 36.1 fb$^{-1}$ at a centre-of-mass energy $\sqrt{s}=13$ TeV. No significant excess of events above Standard Model background predictions is observed; therefore, upper limits at 95% confidence level are set on model-independent fiducial cross-sections, and on the Higgs boson decay branching ratios to vector and pseudoscalar bosons in two benchmark models.

description: Kinetic energy (KE) approximations are key elements in orbital-free density functional theory. To date, the use of non-local functionals, possibly employing system dependent parameters, has been considered mandatory in order to obtain satisfactory accuracy for different solid-state systems, whereas semilocal approximations are generally regarded as unfit to this aim. Here, we show that instead properly constructed semilocal approximations, the Pauli-Gaussian (PG) KE functionals, especially at the Laplacian-level of theory, can indeed achieve similar accuracy as non-local functionals and can be accurate for both metals and semiconductors, without the need of system-dependent parameters.

description: AbstractThe current pandemic of SARS-COV 2 infection (Covid-19) is challenging health systems and communities worldwide. At the individual level, the main biological system involved in Covid-19 is the respiratory system. Respiratory complications range from mild flu-like illness symptoms to a fatal respiratory distress syndrome or a severe and fulminant pneumonia. Critically, the presence of a pre-existing cardiovascular disease or its risk factors, such as hypertension or type II diabetes mellitus, increases the chance of having severe complications (including death) if infected by the virus. In addition, the infection can worsen an existing cardiovascular disease or precipitate new ones.This paper presents a contemporary review of cardiovascular complications of Covid-19. It also specifically examines the impact of the disease on those already vulnerable and on the poorly resourced health systems of Africa as well as the potential broader consequences on the socio-economic health of this region.
Time-resolved quantum spin transport through an Aharonov-Casher ring

description: After obtaining an exact analytical time-varying solution for the Aharonov-Casher conducting ring embedded in a textured static/dynamic electric field, we investigate the spin-resolved quantum transport in the structure. It is shown that the interference patterns are governed by not only the Aharonov-Casher geometry phase but also the instantaneous phase difference of spin precession through different traveling paths. This dynamic phase is determined by the strength of applied electric field and can have substantial effects on the charge/spin conductances, especially in the weak field regime as the period of spin precession comparable to that of the orbital motion. Our studies suggest that a low-frequency normal electric field with moderate strength possesses more degrees of freedom for manipulating the spin interference of incident electrons.

description: Individual socio-demographic characteristics influence the composition of residential environments, employment considerations and transport-dedicated resources, all of which influence individual travel behaviours. To analyse these interrelationships, we employ generalised structural equation modelling using individual-level data from the 2016 Irish Census on workers across the Republic of Ireland alongside highly spatially disaggregated residential built and social environment data. This allows us to consider the non-linear relationships between multiple variables known to influence travel behaviours and provide direction for future policymaking. We find that regardless of socio-demographic compositions, increased developmental compactness and infrastructure quality are associated with increased public and active travel.
Search for a heavy Higgs boson decaying into a $Z$ boson and another heavy Higgs boson in the $\ell\ell bb$ final state in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for a heavy neutral Higgs boson, $A$, decaying into a $Z$ boson and another heavy Higgs boson, $H$, is performed using a data sample corresponding to an integrated luminosity of 36.1 fb$^{-1}$ from proton-proton collisions at $\sqrt{s} = 13$ TeV recorded in 2015 and 2016 by the ATLAS detector at the Large Hadron Collider. The search considers the $Z$ boson decaying to electrons or muons and the $H$ boson into a pair of $b$-quarks. No evidence for the production of an $A$ boson is found. Considering each production process separately, the 95% confidence-level upper limits on the $pp\rightarrow A\rightarrow ZH$ production cross-section times the branching ratio $H\rightarrow bb$ are in the range of 14-830 fb for the gluon-gluon fusion process and 26-570 fb for the $b$-associated process for the mass ranges 130-700 GeV of the $H$ boson and process for the mass ranges 130-700 GeV of the $H$ boson and 230-800 GeV of the $A$ boson. The results are interpreted in the context of the two-Higgs-doublet model.

description: In this paper, we present an eleven invariant isotropic irreducible function basis of a third order three-dimensional symmetric tensor. This irreducible function basis is a proper subset of the Olive-Auffray minimal isotropic integrity basis of that tensor. The octic invariant and a sextic invariant in the Olive-Auffray integrity basis are dropped out. This result is of significance to the further research of irreducible function bases of higher order tensors.
The Singlet Majoron Model with Hidden Scale Invariance

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

description: We investigate an extension of the Singlet Majoron Model in which the breaking of dilatation symmetry by the mass parameters of the scalar potential is removed by means of a dilaton field. Starting from the one-loop renormalization group improved potential, we discuss the ground state of the theory. The flat direction in the classical potential is lifted by quantum corrections and the true vacua are found. Studying the finite temperature potential, we analyze the cosmological consequences of a Jordan-Brans-Dicke dilaton and show that the lepton number is spontaneously broken after the electroweak phase transition, thus avoiding any constraint coming from the requirement of the preservation of the baryon asymmetry in the early Universe. We also find that, contrary to the Standard Model case, the dilaton cosmology does not impose any upper bound on the scale of the spontaneous breaking of scale invariance.

description: In skew-product systems with contractive factors, all orbits asymptotically approach the graph of the so-called sync function; hence, the corresponding regularity properties primarily matter. In the literature, sync function Lipschitz continuity and differentiability have been proved to hold depending on the derivative of the base reciprocal, if not on its Lyapunov exponent. However, forcing topological features can also impact the sync function regularity. Here, we estimate the total variation of sync functions generated by one-dimensional Markov maps. A sharp condition for bounded variation is obtained depending on parameters, that involves the Markov map topological entropy. The results are illustrated with examples.
Exporting unemployment? Assessing the impact of German import competition on regional manufacturing employment in France

description: This paper assesses the extent to which German import competition has contributed to the observed differential decline in manufacturing employment across French regions. The study employs an exposure research design that exploits differences in regional manufacturing specialisation across French départements combined with an instrumental variable strategy. The analysis does not establish a connection between German import competition and differential changes in regional French manufacturing employment. This result suggests that German import competition has neither driven nor halted the overall decline of French manufacturing employment. It also indicates that the sizeable and long-lasting negative regional employment effects of trade between China and developed countries do not necessarily generalise.
