This paper explores the interface between central banks and cryptocurrencies. Focusing on the European Central Bank (ECB), it identifies the potential threats that the rise of cryptocurrencies would pose to the basic and ancillary tasks of the ECB, in particular, its monetary policy operations and the exercise of its supervisory functions over credit institutions and payment systems. The paper finds that cryptocurrencies can potentially have both direct – through their potential impact on the price stability and monetary policy, and central banks’ monopoly over issuing base money – and indirect effects on central banks, mainly through the institutions and systems that fall under the ECB’s scope of competence. To address the challenges posed by cryptocurrencies, the ECB may take both legal (including supervisory and oversight) measures and non-legal (or technical) measures. With respect to technical measures, the ECB - to the extent falling within the scope of its competence - may focus on improving the efficiency of existing payment systems and addressing the existing frictions in market infrastructures to indirectly affect the cryptocurrency markets. Alternatively, it can venture into issuing Central Bank Digital Currency (CBDC). Regarding legal measures, central banks could envisage regulating cryptocurrencies either directly or indirectly. However, as the most significant potential impact of cryptocurrencies on central banks is likely to be indirect through the impact of cryptocurrencies on the banking and payment systems, and given the limitations on the ECB’s mandate and its regulatory and supervisory tools, it is apposite for the ECB to consider using indirect strategies and tools to influence cryptocurrency markets. This indirect approach can be implemented through the ECB’s existing supervisory and oversight powers over the banking and payment systems. This paper specifies the direct and indirect measures and assesses their merits in addressing the concerns about cryptocurrencies. [less ▲]

Für die großflächige, deutschlandweite Kartierung und Analyse der Familiennamen (FamilienN, im Folgenden steht „N“ für Name(n)) stellt bis heute die nach Postleitzahlen gegliederte Datenbank der Telefonanschlüsse, wie sie im Telefonbuch der Deutschen Telekom von 2005 verzeichnet sind die Datenbasis des Projekts 'Deutscher Familiennamenatlas' dar. Im Folgenden werden wir eine neue umfangreiche Datenbasis der deutschen FamilienN vorstellen, die die bisherige um eine historische Dimension erweitern wird. Es handelt sich um die Datenbank der Verlustlisten der Kriegsteilnehmer des Ersten Weltkriegs, die mit ihren rund 7,7 Millionen Namenträgern aus allen Gebieten des damaligen Deutschen Reichs die gesamte FamilienN-Landschaft des ausgehenden 19. Jh. umfassen. Mit dieser neuen Datenbasis wird es möglich sein, die heutige FamilienN-Landschaft mit derjenigen vor 130 Jahren zu vergleichen und damit zum ersten Mal die regionale Festigkeit bzw. Veränderung der FamilienN zu erforschen. Unberührt von den großen europäischen Migrationswellen des 20. Jh. und erst am Beginn der durch die Industrialisierung beschleunigten Urbanisierung, repräsentieren die Verlustlisten die Namenverteilung einer im Vergleich zu heute deutlich weniger mobilen, überwiegend ländlichen Gesellschaft. Über diese neue Kartierungsgrundlage hinaus leisten die Verlustlisten wertvolle Dienste bei der Etymologisierung, bei sprachgeschichtlichen, dialektologischen oder graphematischen Fragestellungen sowie für die Migrationsforschung.

In this paper, the cell based smoothed finite element method is extended to solve stochastic partial diff erential equations with uncertain input parameters. The spatial field of Young's moduli and the corresponding stochastic results are represented by Karhunen-Lo eve expansion and polynomial chaos expansion, respectively. The Young's Modulus of structure is considered to be random for stochastic static as well as free vibration problems. Mathematical expressions and the solution procedure are articulated in detail to evaluate the statistical characteristics of responses in terms of static displacements and free vibration frequencies. The feasibility and eff ectiveness of the proposed SGCS-FEM method in terms of accuracy and lower requirement on the mesh size in the solution domain over that of conventional FEM for stochastic problems are demonstrated by carefully chosen numerical examples. From the numerical study, it is inferred that the proposed framework is computationally less demanding without compromising accuracy. [less ▲]

We study the problem of computing a minimal subset of nodes of a given asynchronous Boolean network that need to be perturbed in a single-step to drive its dynamics from an initial state to a target steady state (or attractor), which we call the source-target control of Boolean networks. Due to the phenomenon of state-space explosion, a simple global approach that performs computations on the entire network, may not scale well for large networks. We believe that efficient algorithms for such networks must exploit the structure of the networks together with their dynamics. Taking this view, we derive a decomposition-based solution to the minimal source-target control problem which can be significantly faster than the existing approaches on large networks. We then show that the solution can be further optimised if we take into account appropriate information about the source state. We apply our solutions to both real-life biological networks and randomly generated networks, demonstrating the efficiency and efficacy of our approach. [less ▲]

Intergenerational value transmission occurs widely and to a large extent within the family as primary socialization agent. In families, children are confronted with specific practices, paradigms, rules and routines which are part of their family culture (Albert & Barros Coimbra, 2017) and as such family is a mediator between societal/cultural and individual values. The ability to transmit values is essential for collective knowledge and memory, the continuity of value orientations being a main feature of intergenerational relations that enables members of different generations to communicate with each other (Barni, Rosnati, & Ranieri, 2013; Halbwachs, 1941/1992; Schönpflug, 2001). Intergenerational transmission of values becomes particularly complex in the context of migration or in times of rapid social change. On the one hand, family identity and traditions might provide a secure base in light of a changing context, and parents might find it important to transmit traditional values to the next generation in order to keep memories alive. At the same time, they might feel that their children should adapt to the changed cultural context, resulting in a (not always clear) dilemma about what they want for their children. How can migrant parents reconcile or move between the different collective frameworks of their culture of origin and the receiving culture (Middleton & Brown, 2005)? In the following, we will first give a brief overview over research in the area of intergenerational value transmission, and we will second illustrate and further inform our theoretical assumptions by identifying related themes and phenomena in our qualitative dyadic interviews. Then, we will delve into memory as a horizon that is emerging out of the analysis as a transversal theme. From this point of view, we continue the analysis and progressively integrate the notions pertaining to the role of memory in the intergenerational transmission of values. Aspects of cultural background are apparent in the excerpts that we will quote supporting the themes we will refer to. We will more explicitly return to this in our conclusions. [less ▲]

Anxiety symptoms and anxiety disorders are highly prevalent among older adults, and are associ- ated with considerable distress, functional impairment, and burden. Also, there is growing need for brief instruments to measure anxiety symptoms in primary care and geriatric medical settings. Therefore, the current study focuses on the development and psychometric evaluation of a short- form of the Geriatric Anxiety Scale (GAS-G), a well-established anxiety instrument for use with older adults. Study 1 draws on the original data from the GAS-G validation study (N1⁄4242) to develop the short-form (GAS-G-SF) and determines whether the results replicate with the short- form. Study 2 extends the validation of the GAS-G-SF to a clinical sample (N1⁄4156; 62 patients with heart disease, 94 patients with Parkinson’s disease). Overall, the GAS-G-SF showed promising psychometric properties in terms of internal consistency and validity. Also, the GAS-G-SF showed good discriminatory power based on receiver operating characteristic curve analysis in both stud- ies. These results support the utility of the GAS-G-SF as a brief assessment measure for anxiety. [less ▲]

In a time of worldwide availability of annual age-specific mortality data, we lack basic tools for detecting and graphing, from a comparative perspective, fine-grained deviations from mortality trends. We provide a new age-period-cohort-based methodology, combining information from age-period (AP) and APC-Detrended (APCD) analyses to detect all-cause mortality increases. Plotting the resulting AP coefficients and APCD residuals in equilateral Lexis diagrams, mortality patterns can easily be distinguished as age, period, or cohort trends and fluctuations. We highlight abnormalities as interactions of age and period (‘Black Holes’). We then investigate the ‘Black Holes’ of mortality of young-adult cohorts in the early 1990s in Spain, other southern European countries, and the U.S., in emphasizing their simultaneously occurring mortality crises. Additional analyses with WHO mortality data and epidemiological evidence from other studies show that these mortality increases likely result from lack of treatment and inadequate public health responses to the beginnings of the HIV/AIDS epidemic. We discuss other possible applications of the new method. [less ▲]

For many models of solids, we frequently assume that the material parameters do not vary in space, nor that they vary from one product realization to another. If the length scale of the application approaches the length scale of the micro-structure however, spatially fluctuating parameter fi elds (which vary from one realization of the fi eld to another) can be incorporated to make the model capture the stochasticity of the underlying micro-structure. Randomly fluctuating parameter fields are often described as Gaussian fields. Gaussian fi elds however assume that the probability density function of a material parameter at a given location is a univariate Gaussian distribution. This entails for instance that negative parameter values can be realized, whereas most material parameters have physical bounds (e.g. the Young's modulus cannot be negative). In this contribution, randomly fluctuating parameter fi elds are therefore described using the copula theorem and Gaussian fi elds, which allow di fferent types of univariate marginal distributions to be incorporated, but with the same correlation structure as Gaussian fields. It is convenient to keep the Gaussian correlation structure, as it allows us to draw samples from Gaussian fi elds and transform them into the new random fields. The bene fit of this approach is that any type of univariate marginal distribution can be incorporated. If the selected univariate marginal distribution has bounds, unphysical material parameter values will never be realized. We then use Bayesian inference to identify the distribution parameters (which govern the random fi eld). Bayesian inference regards the parameters that are to be identi fied as random variables and requires a user-defi ned prior distribution of the parameters to which the observations are inferred. For the homogenized Young's modulus of a columnar polycrystalline material of interest in this study, the results show that with a relatively wide prior (i.e. a prior distribution without strong assumptions), a single specimen is su ciffient to accurately recover the distribution parameter values.
