We test the welfare magnet hypothesis for Europe. We modify the existing theoretical frameworks assuming that: (a) welfare services, intended as the output of welfare expenditure, not the poor’s income or social expenditure, enter the median voter’s utility function; (b) preferences depend on the position of the median voter in the income distribut...

The syntactic and semantic analyses of 2,500 dish names retrieved from 112 restaurant, tavern, and patisserie menus in Eastern Macedonia and in Thrace in Northern Greece show that only a small number of concepts are denoted by the heads of these noun phrases (NPs): Main Ingredient (MI) of a dish, Way of preparation, Part or Cuts (for MIs with an an...

Given a square matrix A, replacing each of its nonzero entries with the symbol * gives its zero-nonzero pattern. Such a pattern is said to be spectrally arbitrary when it carries essentially no information about the eigenvalues of A. A longstanding open question concerns the smallest possible number of nonzero entries in an n × n spectrally arbitra...

Transcatheter Aortic Valve Implantation (TAVI) has become today a popular alternative technique to surgical valve replacement for critical patients. However, with only six years follow up on average, little is known about the long-term durability of transcatheter implanted biological tissue. Moreover, the high cost of tissue harvesting and chemical...

The Re3B type, space group Cmcm, has boron-centered trigonal prisms as central building units and is one of the basic structure types with numerous binary and ternary representatives. The coloring of different atoms on the two crystallographically independent rhenium sites leads to a manifold of compounds with different bonding peculiarities that a...

This paper uses data from the Health and Retirement Study to investigate the role of inheritances for stockholding. Individual heir fixed-effects estimates show that an inheritance receipt increases subsequent stock market participation. The respective magnitude of this shift is higher for large and fully anticipated receipts, whereas it seems to b...

A model for the transmission dynamics of Ebola virus in a multipatch network setting is studied. The model considers the contribution to the dynamics by people who are susceptible, infectious, isolated, deceased but still infectious and not yet buried, as well as the dynamics of the pathogen at interacting nodes or patches. Humans can move between ...

The archaeological discussion still appears to largely disregard the role of natural resources in the early agricultural economy of Central Europe. Cereal cultivation and animal husbandry strategies remain a central area of studies. Wild resources are the only proxy data helping to reconstruct the strategies mentioned above. The data for the assess...

Many tasks that until recently could only be performed by humans are now entrusted to machines. Automation plays an increasingly important role in many areas of life, and its special role is observed in broadly understood transport, affecting the mobility, behaviour, and safety of drivers. Faced with the threat of a large number of accidents, death...

In this paper, we prove some existence results of solutions for a class of nonlocal initial value problem for nonlinear fractional hybrid implicit differential equations under generalized Hilfer fractional derivative. The result is based on a fixed point theorem on Banach algebras. Further, examples are provided to illustrate our results.
