    Headquarters (HQs) represent central units within corporationsi and their goal is to add value to the firm and its respective subunits. They do so by taking over various responsibilities, such as allocating resources within the firm, coordinating and monitoring subunits, and identifying and realizing synergies, among others. HQs are also important for the economy of the countries they are located in, as they offer for example high-value employment, increased demand for related business services (e.g., legal and financial services), and represent a non-trivial source of tax income. Additionally, there is scientific evidence suggesting that the location of the HQ influences its investment decisions and consequently adjacent economies (e.g., investments that are in regions close to the HQ are favoured). Thus, many countries consider it important to attract and maintain HQsii. In this article, we will focus on a topic that has not received much attention yet. Specifically, we discuss how digitalization (i.e., recent advancements in areas such as big data analytics, automation, artificial intelligence, the internet of things, etc.) influences HQs in Austria, most of which have a strong focus on CEE countries. Companies are dealing with a variety of issues stemming from digitalization, which results in changes to business models, firm processes, and company culturesiii. Yet, digitalization also affects the role and value added of the HQs but we still lack a clear understanding of thativ. In the following, we first discuss Austria as a location for HQs, then the impact of digitalization on HQs, and finally, we explore how the digitalization might influence the attractiveness of Austria for CEE-oriented HQs. Thereby, we refer to recent empirical material that we have collected

    Parental Leave Policies in 21 Countries: Assessing Generosity and Gender Equality

    This report examines the parental leave policies in 21 high-income nations and identifies five "best practices" for parental leave policies. The study shows that the U.S. has the least generous leave policies of the 21 countries examined in the report. The states exhibiting the five best practices include Finland, France, Greece, Norway, Spain, and Sweden

    Bottom and charm production at LHC and RHIC

    Get PDF
    We study b¯b and c¯c production and the influence of nuclear shadowing at LHC and RHIC energies. We find a significant reduction in the production cross section of both charm and bottom at RHIC and LHC. Bound states such as and J/psi are suppressed by this reduction in the charm production cross sections. Therefore, J/psi suppression may not be useful as a signature for the quark gluon plasma.

    Resonant activation: a strategy against bacterial persistence

    A bacterial colony may develop a small number of cells genetically identical to, but phenotypically different from other normally growing bacteria. These so-called persister cells keep themselves in a dormant state and thus are insensitive to antibiotic treatment, resulting in serious problems of drug resistance. In this paper, we proposed a novel strategy to "kill" persister cells by triggering them to switch, in a fast and synchronized way, into normally growing cells that are susceptible to antibiotics. The strategy is based on resonant activation (RA), a well-studied phenomenon in physics where the internal noise of a system can constructively facilitate fast and synchronized barrier crossings. Through stochastic Gilliespie simulation with a generic toggle switch model, we demonstrated that RA exists in the phenotypic switching of a single bacterium. Further, by coupling single cell level and population level simulations, we showed that with RA, one can greatly reduce the time and total amount of antibiotics needed to sterilize a bacterial population. We suggest that resonant activation is a general phenomenon in phenotypic transition, and can find other applications such as cancer therapy.Comment: 21 pages, 12 figures, submitte

    Skyrme models and nuclear matter equation of state

    Get PDF
    We investigate the role of pressure in a class of generalised Skyrme models. We introduce pressure as the trace of the spatial part of the energy-momentum tensor and show that it obeys the usual thermodynamical relation. Then, we compute analytically the mean-field equation of state in the high and medium pressure regimes by applying topological bounds on compact domains. The equation of state is further investigated numerically for the charge one skyrmions. We identify which term in a generalised Skyrme model is responsible for which part in the equation of state. Further, we compare our findings with the corresponding results in the Walecka model

    Critical properties of the one-dimensional spin-1/2 antiferromagnetic Heisenberg model in the presence of a uniform field

    Full text link
    In the presence of a uniform field the one-dimensional spin-12\frac{1}{2} antiferromagnetic Heisenberg model develops zero frequency excitations at field-dependent 'soft mode' momenta. We determine three types of critical quantities, which we extract from the finite-size dependence of the lowest excitation energies, the singularities in the static structure factors and the infrared singularities in the dynamical structure factors at the soft mode momenta. We also compare our results with the predictions of conformal field theory.Comment: 12 pages, REVTEX, 7 figures, submitted to Physical Review
