description: We experimentally analyze three anti-tax-evasion mechanisms: (1) prefilling of deductions in tax returns, (2) restricting tax evasion opportunities by either disallowing or (3) limiting the deductibility of expenditures. We find that prefilling compared to blank forms reduces tax evasion. Cutting the number of tax evasion opportunities by disallowing the deductibility of expenditure items is an ineffective mechanism to combat tax evasion as individuals shift their tax evasion activities from the disallowed item to other non-restricted items. In contrast, our results suggest that just limiting the deductibility of expenditures avoids this evasion-shift-effect.

description: We study the possibility to reproduce the statistical relations of the sunspot activity cycle, like the so-called Waldmeier relations, the cycle period - amplitude and the cycle rise rate - amplitude relations, by means of the mean field dynamo models with the fluctuating α-effect. The dynamo model includes the long-term fluctuations of the α-effect and two types of the nonlinear feedback of the mean-field on the α-effect including the algebraic quenching and the dynamic quenching due to the magnetic helicity generation. We found that the models are able to reproduce qualitatively and quantitatively the inclination and dispersion across the Waldmeier relations with the 20% fluctuations of the α-effect. The models with the dynamic quenching are in a better agreement with observations than the models with the algebraic α-quenching. We compare the statistical distributions of the modeled parameters, like the amplitude, period, the rise and decay rates of the sunspot cycles, with observations.

Approximate invariance of metabolic energy per synapse during development in mammalian brains

description: During mammalian development the cerebral metabolic rate correlates qualitatively with synaptogenesis, and both often exhibit bimodal temporal profiles. Despite these non-monotonic dependencies, it is found based on empirical data for different mammals that regional metabolic rate per synapse is approximately conserved from birth to adulthood for a given species (with a slight deviation from this constancy for human visual and temporal cortices during adolescence). A typical synapse uses about $(7\pm 2)\cdot 10^{3}$ glucose molecules per second in primate cerebral cortex, and about 5 times of that amount in cat and rat visual cortices. A theoretical model for brain metabolic expenditure is used to estimate synaptic signaling and neural spiking activity during development. It is found that synaptic efficacy is generally inversely correlated with average firing rate, and additionally, synapses consume a bulk of metabolic energy, roughly $50-90 %$ during most of the developmental process (except human temporal cortex $ < 50%$). Overall, these results suggest a tight regulation of brain electrical and chemical activities during the formation and consolidation of neural connections. This presumably reflects strong energetic constraints on brain development.

A Random Dynamical Systems Perspective on Isochronicity for Stochastic Oscillations

description: For an attracting periodic orbit (limit cycle) of a deterministic dynamical system, one defines the isochron for each point of the orbit as the cross-section with fixed return time under the flow. Equivalently, isochrons can be characterized as stable manifolds foliating neighborhoods of the limit cycle or as level sets of an isochron map. In recent years, there has been a lively discussion in the mathematical physics community on how to define isochrons for stochastic oscillations, i.e. limit cycles or heteroclinic cycles exposed to stochastic noise. The main discussion has concerned an approach finding stochastic isochrons as sections of equal expected return times versus the idea of considering eigenfunctions of the backward Kolmogorov operator. We discuss the problem in the framework of random dynamical systems and introduce a new rigorous definition of stochastic isochrons as random stable manifolds for random periodic solutions with noise-dependent period. This allows us to establish a random version of isochron maps whose level sets coincide with the random stable manifolds. Finally, we discuss links between the random dynamical systems interpretation and the equal expected return time approach via averaged quantities.

What Velocities and Eccentricities tell us about Radial Migration

Publisher: name: arXiv
Year: 2011
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: This note attempts to interpret some of the recent findings about a downtrend in the mean azimuthal velocity of low [alpha/Fe] thin disc stars with increasing metallicity. The presence of such a trend was predicted in the model of Schoenrich & Binney (2009), albeit with a slightly steeper slope. We show that in a simple picture a Galactic disc without mixing in angular momenta would display an exceedingly steep trend, while in the case of complete mixing of all stars the trend has to vanish. The difference between model and observational data can hence be interpreted as the consequence of the radial abundance gradient in the model being too high resulting in an underestimate of the migration strength. We shortly discuss the value of eccentricity distributions in constraining structure and history of the Galactic disc.

Zero Energy Modes and Gate-Tunable Gap in Graphene on hexagonal Boron Nitride

description: In this Letter, we derive an effective theory of graphene on a hexagonal Boron Nitride (h-BN) substrate. We show that the h-BN substrate generically opens a spectral gap in graphene despite the lattice mismatch. The origin of that gap is particularly intuitive in the regime of strong coupling between graphene and its substrate, when the low-energy physics is determined by the topology of a network of zero energy modes. For twisted graphene bilayers, where inversion symmetry is present, this network percolates through the system and the spectrum is gapless. The breaking of that symmetry by h-BN causes the zero energy modes to close into rings. The eigenstates of these rings hybridize into flat bands with gaps in between. The size of this band gap can be tuned by a gate voltage and it can reach the order of magnitude needed to confine electrons at room temperature.

description: The life histories of four species of limnephilid caddisflies in a permanent pond in southern Alberta were investigated. Nemotaulius hostilis overwinters in the larval stage and displayed other life history traits restricting it to life in permanent aquatic habitats. Limnephilus externus and Anabolia bimaculata overwinter out of water in desiccation-resistant egg masses as first instar larvae and so can also survive in temporary pool habitats. Glyphopsyche irrorata is primarily a permanent pool resident but can survive winter drought conditions because it overwinters in the adult stage. Incubation experiments showed that L. externus eggs, which are deposited on the ground in autumn, are adapted to developing over a wide range of temperatures and at cooler temperatures than are the eggs of~ hostilis, which oviposits on riparian vegetation in mid-summer. L. externus eggs developed in both water and air whereas N. hostilis eggs developed only when out of water. SEM studies of the structure of the polysaccharide matrix of the gelatinous egg masses of five species of caddisflies and a snail revealed a relationship between structure and desiccation-resistance. The results of the SEM study indicated that egg mass structure may provide information of taxonomic and phylogenetic importance concerning the Trichoptera. All four species studied are shredders. The two species capable of surviving in temporary pool habitats (h externus and A. bimaculata) displayed the highest larval growth rates of the four species studied. Laboratory experiments indicated that caddisfly larval feeding preferences are a combination of preferences for food and case-building materials. The patterns of emergence, maturation, mating and ovi position indicated that adult G. irrorata and A. bimaculata did not undergo a reproductive developmental delay whereas adults of both sexes of L. externus and N. hostilis did. The evolution of life history traits (including oviposition out of water) enabling limnephilid caddisflies to survive in temporary pool habitats is viewed in terms of the Thermal Equilibrium Hypothesis. The widespread occurrence of adult reproductive developmental delays in this family is seen as an adaptation enabling animals to avoid the high, metabolically-costly water temperatures of mid-summer. Adult reproductive delays and oviposition out of water may thus have preadapted members of the Limnephilidae to exploiting temporary aquatic habitats.

description: Rips complexes are important structures for analyzing topological features of metric spaces. Unfortunately, generating these complexes is expensive because of a combinatorial explosion in the complex size. For n points in Rd, we present a scheme to construct a 2-approximation of the filtration of the Rips complex in the L∞-norm, which extends to a 2d0.25-approximation in the Euclidean case. The k-skeleton of the resulting approximation has a total size of n2O(dlogk+d). The scheme is based on the integer lattice and simplicial complexes based on the barycentric subdivision of the d-cube. We extend our result to use cubical complexes in place of simplicial complexes by introducing cubical maps between complexes. We get the same approximation guarantee as the simplicial case, while reducing the total size of the approximation to only n2O(d) (cubical) cells. There are two novel techniques that we use in this paper. The first is the use of acyclic carriers for proving our approximation result. In our application, these are maps which relate the Rips complex and the approximation in a relatively simple manner and greatly reduce the complexity of showing the approximation guarantee. The second technique is what we refer to as scale balancing, which is a simple trick to improve the approximation ratio under certain conditions.

description: Synchrotron radiation mechanism, when electrons are accelerated in a relativistic shock, is known to have serious problems to explain the observed gamma-ray spectrum below the peak for most Gamma-Ray Bursts (GRBs); the synchrotron spectrum below the peak is much softer than observed spectra. Recently, the possibility that electrons responsible for the radiation cool via Inverse Compton, but in the Klein-Nishina regime, has been proposed as a solution to this problem. We provide an analytical study of this effect and show that it leads to a hardening of the low energy spectrum but not by enough to make it consistent with the observed spectra for most GRBs (this is assuming that electrons are injected continuously over a time scale comparable to the dynamical time scale, as is expected for internal shocks of GRBs). In particular, we find that it is not possible to obtain a spectrum with α>-0.1 (f_ν \propto ν^α) whereas the typical observed value is α\sim0. Moreover, extreme values for a number of parameters are required in order that α\sim-0.1: the energy fraction in magnetic field needs to be less than about 10^{-4}, the thermal Lorentz factor of electrons should be larger than 10^6, and the radius where gamma-rays are produced should be not too far away from the deceleration radius. These difficulties suggest that the synchrotron radiation mechanism in internal shocks does not provide a self-consistent solution when α>-0.2.

description: Spermidine is a natural polyamine, central to cellular homeostasis and growth, that promotes macroautophagy/autophagy. The polyamine pathway is highly conserved from bacteria to mammals and spermidine (prominently found in some kinds of aged cheese, wheat germs, nuts, soybeans, and fermented products thereof, among others) is an intrinsic part of the human diet. Apart from nutrition, spermidine is available to mammalian organisms from intracellular biosynthesis and microbial production in the gut. Importantly, externally supplied spermidine (via drinking water or food) prolongs lifespan, activates autophagy, improves mitochondrial function, and refills polyamine pools that decline during aging in various tissues of model organisms, including mice. In two adjacent studies, we explored how dietary spermidine supplementation enhances eEF5/EIF5A hypusination, cerebral mitochondrial function and cognition in aging Drosophila melanogaster and mice.

description: GEM103 is a recombinantly produced full-length version of the human complement factor H (CFH) under clinical investigation for treatment of age-related macular degeneration (AMD) in individuals carrying an AMD risk-associated genetic variant of CFH. This study aimed to investigate the complement pathway-related functions of GEM103 in comparison with those of native human CFH. Key biological activities of GEM103 and human serum-derived CFH (sdCFH) were compared using four independent functional assays. Assays of C3b binding and C3 convertase decay-accelerating activity (DAA) were performed by surface plasmon resonance (SPR). Cofactor activity (CA) was measured using 8-anilinonaphthalene-1-sulfonic acid as a fluorescent probe of C3b integrity. The abilities of GEM103 and sdCFH to protect sheep erythrocytes from hemolysis by CFH-depleted normal human serum were assessed colorimetrically. In multiple SPR-based assays of C3b binding and DAA, the performance of GEM103 was consistently comparable to that of sdCFH across a range of matching concentrations. The EC50 ± SD in the fluorescence-based fluid-phase CA assay was 0.21 ± 0.06 µM for GEM103 compared to 0.20 ± 0.09 µM for sdCFH. In hemolysis assays, the EC50 value of 0.33 ± 0.16 µM for GEM103 versus 0.46 ± 0.06 µM for sdCFH were not significantly different (p = 0.81). GEM103, a recombinant CFH developed by Gemini Therapeutics, shows activity profiles comparable to sdCFH in all complement-related assays employed in this study, suggesting that GEM103 is equivalent to the native glycoprotein in terms of its in vitro functional activity. These results support further study of GEM103 as a potential therapy for AMD.
Development of Fungistatic Plant Extracts From Food Waste And Oil Based Products To Control Turf-Grass Disease

Publisher: name: Lancaster University

description: Synthetic pesticide use has many established detriments such as direct negative effects on soils, plants, insects, small animals (and the entire ecosystem, potentially), the environment and even human health. Furthermore, there are more abstract concerns linked to pesticide use, such as encouraging the emergence of antimicrobial resistance. There is a global need to reduce synthetic pesticide use, while encourage the adoption of alternative methods for pest control such as biological products and integrated pest management strategies. There is a great deal of evidence for the potential utility of essential oils and other natural extracts as antimicrobial agents, especially potent as a counter to the growing problem of antimicrobial resistance, but in practice heavy utilisation of natural products is relatively scarce, primarily due to a lack of confidence in their performance and relatively high cost of production and therefore purchase. Using very green techniques (steam distillation and crude aqueous ‘solvent’ powdered plant material extraction), a number of natural extracts were obtained and formulated such as spent hops oil and a macerated onion aqueous extract. These extracts were then tested in bioassays against some common fungal pathogens (M. nivale, L. fuciformis and C. cereale) which cause diseases in turf grasses, using simple potato dextrose agar well diffusion, in order to determine the antifungal capability of extracts. Ultimately, several essential oilbased, waste derived fungicides, such as the emulsified spent hops essential oil and an aqueous plum extract, were produced and provided disease control of three pathogenic fungal species in laboratory conditions. Additionally, some aqueous extracts provided comparable and even enhanced antifungal capacity when compared to some oils. This provides a foundation for field testing to determine the ability of these natural, waste-based, extracts to control disease in commercial conditions. The potential benefits of uptake of any such extracts are prolific, including improvement in soil health, countering the emergence of antimicrobial resistance, reduced atmospheric CO2 as a result of synthetic chemical replacement with food waste utilisation).

description: We derive QCD light-cone sum rules for the hadronic matrix elements of the heavy baryon transitions to nucleon. In the correlation functions the $Λ_c,Σ_c$ and $Λ_b$ -baryons are interpolated by three-quark currents and the nucleon distribution amplitudes are used. To eliminate the contributions of negative parity heavy baryons, we combine the sum rules obtained from different kinematical structures. The results are then less sensitive to the choice of the interpolating current. We predict the $Λ_{b}\to p$ form factor and calculate the widths of the $Λ_{b}\to p\ellν_l$ and $Λ_{b}\to p π$ decays. Furthermore, we consider double dispersion relations for the same correlation functions and derive the light-cone sum rules for the $Λ_cND^{(*)}$ and $Σ_cND^{(*)}$ strong couplings. Their predicted values can be used in the models of charm production in $p\bar{p}$ collisions.

description: In ophthalmology, data from both eyes of a person are frequently included in the statistical evaluation. This violates the requirement of data independence for classical statistical tests (e.g. t-Test or analysis of variance (ANOVA)) because it is correlated data. Linear mixed models (LMM) were used as a possibility to include the data of both eyes in the statistical evaluation. The LMM is available for a variety of statistical software such as SPSS or R. The application was applied to a retrospective longitudinal analysis of an accelerated corneal cross-linking (ACXL (9*10)) treatment in progressive keratoconus (KC) with a follow-up period of 36 months. Forty eyes of 20 patients were included, whereas sequential bilateral CXL treatment was performed within 12 months. LMM and ANOVA for repeated measurements were used for statistical evaluation of topographical and tomographical data measured by Pentacam (Oculus, Wetzlar, Germany). Both eyes were classified into a worse and better eye concerning corneal topography. Visual acuity, keratometric values and minimal corneal thickness were statistically significant between them at baseline (p < 0.05). A significant correlation between worse and better eye was shown (p < 0.05). Therefore, analyzing the data at each follow-up visit using ANOVA partially led to an overestimation of the statistical effect that could be avoided by using LMM. After 36 months, ACXL has significantly improved BCVA and flattened the cornea. The evaluation of data of both eyes without considering their correlation using classical statistical tests leads to an overestimation of the statistical effect, which can be avoided by using the LMM.

description: This paper considers the case of the Service Shirt, a proof of concept prototype made as part of a design researchers in residence programme at a fashion brand, within a scientific research consortium. During the development of the concept to prototype stage, many problems arose. In this paper the two authors - co-creators of the prototype - explore the challenges encountered when confronting the theoretical framework of new circular economy business models with the material reality of design collaboration and prototyping. The authors argue for the potential of design-led investigation to expand the lifecycle of garments and offer new insights to understand the challenges of developing circular prototypes within a linear fashion production model. By analysing the different stages of the design and prototyping phase through a combination of adapted annotated portfolio and after-action review methods, four main elements of the project were identified as potential focal points: collaboration, the design challenge, manufacturing, and materials. Throughout these categories, it was found that communication and effective transfer of knowledge were keys to success. For each of these aspects, the authors suggest how the design process may be improved in future iterations.

description: We present spatially resolved Herschel/PACS observations of the Orion Bar. We have characterise the emission of the far-infrared fine-structure lines of [CII] (158um), [OI] (63 and 145um), and [NII] (122um) that trace the gas local conditions. The observed distribution and variation of the lines are discussed in relation to the underlying geometry and linked to the energetics associated with the Trapezium stars. These observations enable us to map the spatial distribution of these fine-structure lines with a spatial resolution between 4" and 11" and covering a total square area of about 120"x105". The spatial profile of the emission lines are modelled using the radiative transfer code Cloudy. We find that the spatial distribution of the [CII] line coincides with that of the [OI] lines. The [NII] line peaks closer to the ionising star than the other three lines, but with a small region of overlap. We can distinguish several knots of enhanced emission within the Bar indicating the presence of an inhomogenous and structured medium. The emission profiles cannot be reproduced by a single photo-dissociation region, clearly indicating that, besides the Bar, there is a significant contribution from additional photo-dissociation region(s) over the area studied. The combination of both the [NII] and [OI] 145um lines can be used to estimate the [CII] emission and distinguish between its ionised or neutral origin. We have calculated how much [CII] emission comes from the neutral and ionised region, and find that at least 82% originates from the photo-dissocciation region. Together, the [CII] 158um and [OI] 63 and 145um lines account for 90% of the power emitted by the main cooling lines in the Bar (including CO, H2, etc...), with [OI] 63um alone accounting for 72% of the total.

description: The preservation of the scholarly record has been a point of concern since the beginning of knowledge production. With print publications, the responsibility rested primarily with librarians, but the shift toward digital publishing and, in particular, the introduction of open access (OA) have caused ambiguity and complexity. Consequently, the long-term accessibility of journals is not always guaranteed, and they can even disappear from the web completely. The focus of this exploratory study is on the phenomenon of vanished journals, something that has not been carried out before. For the analysis, we consulted several major bibliographic indexes, such as Scopus, Ulrichsweb, and the Directory of Open Access Journals, and traced the journals through the Internet Archive's Wayback Machine. We found 174 OA journals that, through lack of comprehensive and open archives, vanished from the web between 2000 and 2019, spanning all major research disciplines and geographic regions of the world. Our results raise vital concern for the integrity of the scholarly record and highlight the urgency to take collaborative action to ensure continued access and prevent the loss of more scholarly knowledge. We encourage those interested in the phenomenon of vanished journals to use the public dataset for their own research.

description: This article presents the results of a series of ethnographic observations at the Berlin fire brigade control and dispatch center during routine and severe weather situations. The weather-related challenges of a fire brigade lie between the anticipation of events and their potential consequences, and the ad hoc reactions to actual impacts of weather. The results show that decisions and actions related to high impact weather are not necessarily motivated by weather warnings alone. Instead, they are reactions to the experience of impacts, for example, an increased number of missions or emergency calls. Impacts are the main trigger for the decision making. Weather is one additional external factor that influences the operational capability of a fire brigade. While commanding officers in a fire brigade control and dispatch center experience weather primarily through technical equipment, verified by ground truth, observations showed that direct personal contact with the regional weather service and colleagues on the ground takes on a greater role in actual severe weather situations. The observations point to the need for increased interagency communication between the emergency services, the weather service, and other organizations to integrate weather information, impacts, and non-weather-related tasks into coherent weather-related decision making.
Patterns of the Aharonov-Bohm oscillations in graphene nanorings

description: Using extensive tight-binding calculations, we investigate (including the spin) the Aharonov-Bohm (AB) effect in monolayer and bilayer trigonal and hexagonal graphene rings with zigzag boundary conditions. Unlike the previous literature, we demonstrate the universality of integer (hc/e) and half-integer (hc/2e) values for the period of the AB oscillations as a function of the magnetic flux, in consonance with the case of mesoscopic metal rings. Odd-even (in the number of Dirac electrons, N) sawtooth-type patterns relating to the halving of the period have also been found; they are more numerous for a monolayer hexagonal ring, compared to the cases of a trigonal and a bilayer hexagonal ring. Additional more complicated patterns are also present, depending on the shape of the graphene ring. Overall, the AB patterns repeat themselves as a function of N with periods proportional to the number of the sides of the rings.

Certain inequalities involving prolate spheroidal wave functions and associated quantities

description: Prolate spheroidal wave functions (PSWFs) play an important role in various areas, from physics (e.g. wave phenomena, fluid dynamics) to engineering (e.g. signal processing, filter design). Even though the significance of PSWFs was realized at least half a century ago, and they frequently occur in applications, their analytical properties have not been investigated as much as those of many other special functions. In particular, despite some recent progress, the gap between asymptotic expansions and numerical experience, on the one hand, and rigorously proven explicit bounds and estimates, on the other hand, is still rather wide. This paper attempts to improve the current situation. We analyze the differential operator associated with PSWFs, to derive fairly tight estimates on its eigenvalues. By combining these inequalities with a number of standard techniques, we also obtain several other properties of the PSFWs. The results are illustrated via numerical experiments.

Diffusive shielding stabilizes bulk nanobubble clusters

description: Using molecular dynamics, we study the nucleation and stability of bulk nanobubble clusters. We study the formation, growth, and final size of bulk nanobubbles. We find that, as long as the bubble-bubble interspacing is small enough, bulk nanobubbles are stable against dissolution. Simple diffusion calculations provide an excellent match with the simulation results, giving insight into the reason for the stability: nanobubbles in a cluster of bulk nanobubbles "protect" each other from diffusion by a shielding effect.

description: Open Science is a founding principle of ELIXIR, a pan-European research infrastructure for life science data, with 21 Member countries plus the European Molecular Biology Laboratory. The mission of ELIXIR is to coordinate bioinformatics resources so that they form a single, integrated and pan-European infrastructure, which can be used freely by academic and private-sector researchers across the globe. As a recipient of public and charitable funding, ELIXIR must demonstrate its value, and the need to produce evidence in support of this is intensifying. Our practice-led journey towards demonstrating public value is articulated around five main challenges and, for each, we present our pragmatic approach for tackling it. We begin by showing how we are working towards demystifying what research infrastructures do. We then shed light on the sort of evidence our funders and other stakeholders are asking us for, how this evidence varies in nature and scope, and our tactics to satisfy them. We follow-on by providing our thoughts on possible barriers and solutions to embedding impact evaluation in our activities. Finally, we provide lessons learned, which we believe are sufficiently transferable and will be inspirational to other research infrastructures as they embark on their own journeys to demonstrate public value.
Dem IT-Fachkräftemangel in deutschen KMUs entgegenwirken: Arbeitsanforderungen und -erwartungen internationaler IT-Fachkräfte

description: In Deutschland herrscht aufgrund des demografischen Wandels ein IT-Fachkräftemangel, der über die Rekrutierung internationaler IT-Fachkräfte abgefangen werden kann. Deren Rekrutierung gestaltet sich für KMUs herausfordernd. CareerBee, ein Start-up für Personal und Karriereberatung, möchte die Attraktivität von KMUs für internationale IT-Fachkräfte über eine Employer Branding erhöhen. Dafür erforscht diese Bachelorthesis, welche Arbeitsanforderungen und -erwartungen internationale IT-Fachkräfte an eine Anstellung in deutschen KMUs haben. Über deren psychologische Vertragserwartung werden relevante Dimensionen für ein Employer Branding erfasst. Anhand einer quantitativen Datenerhebung über einen Online-Fragebogen wurden 60 internationale IT Fachkräfte, im Alter zwischen 24 und 52 Jahren, aus 20 verschiedenen Ländern, befragt. Die Datenauswertung ergibt keine differenzierte Bewertung allgemeiner Anforderungen, weil fast alle Aspekte durch Teilnehmende mit hoher Wichtigkeit bewertet werden. Die Resultate zu Faktoren flexibler Arbeitszeitmodelle zeigen, dass flexible Arbeitszeiten, die Kompensation von Überstunden und Home-Office von mehr als 80 % der Befragten als wichtig erachtet werden. Ergebnisse der Anforderungen an den Bewerbungsprozess weisen auf, dass ein transparenter Bewerbungsprozess, das Kennenlernen des Vorgesetzten und von Arbeitsmitteln, für mehr als 80 % der Teilnehmenden relevant ist. Die Auswertungen von Faktoren in Bezug auf den internationalen Aspekt ergeben, dass ein Visa Sponsorship, die Offenheit gegenüber internationalen IT-Fachkräften und geringen Deutschkenntnissen von über 90 % der Befragten mit hoher Wichtigkeit bewertet werden. Aus den Erkenntnissen wurde ein Konzept in Form eines Guides entwickelt, der KMUs helfen soll, das Optimierungspotential für die Rekrutierungspraxis internationaler IT-Fachkräfte zu verstehen. Zusätzlich soll der Leitfaden KMUs dazu motivieren, ihr Employer Brand über eine individualisierte Beratung mit CareerBee auf internationale IT-Fachkräfte auszurichten.
