Abstract
In recent years, investing with robo-advisors has gained momentum and is seen as a simplifying approach for individual investors to participate in financial markets. This chapter contributes to a better understanding of the concept of a robo-advisory and its implications for private investors by discussing its past, present, and future. It explores key issues, like cost-efficiency, historical performance, and automation levels, based on research and industry insights. Moreover, this chapter examines a robo-advisor's benefits, limitations, and challenges, like behavioral biases, regulation, and risk profiling. Finally, the importance of the ongoing megatrends of AI and green investing is examined concerning a robo-advisory.

Abstract
Purpose
The purpose of this paper is to offer a fast and accurate simulation method for printed spiral radio frequency identification coils and to extract the parameters of an equivalent resonance circuit.
Design/methodology/approach
The frequency‐dependent port impedance of a rectangular spiral multi‐turn antenna is simulated with the non‐retarded partial element equivalent circuit (PEEC) method. The discretization settings needed for an accurate modeling of skin and proximity effects at medium frequencies as well as parasitic capacitances are discussed. Two different PEEC approaches are used, a magneto‐quasi‐static (resistive and inductive cells) model and a non‐retarded (capacitive cells included) model in order to extract a reduced equivalent resonance circuit which is beneficial to describe the inductive coupling to further inductors via the transformer concept.
Findings
With optimized mesh settings, the extremely fast simulation can be carried out just in seconds whereas the results compared to a computationally much more expensive CST Microwave Studio® reference solution as well as an analytical direct current solution show errors of only about a few percent.
Research limitations/implications
The methodology is limited to frequencies up to the first self‐resonant frequency of the coil. In addition, piecewise‐homogeneous materials are implied.
Originality/value
Specialized mesh settings allow for a very fast and accurate simulation of rectangular spiral inductors. A method for the parameter extraction of a resonance circuit is proposed by evaluating two different PEEC models.

Abstract
Since the 1990s, the German current of Value Criticism has been proposing to rework a critique of capitalism based on the mature works of Marx. Starting from the primary categories of capital – value, abstract labor, commodity fetishism – they intend to overcome the traditional contradictions of Marxism, capital/labor, proletariat/bourgeoisie, etc. The Canadian thinker Moishe Postone has, independently of value criticism, developed a thought that is close to the German current while distinguishing itself on certain important points. However, it is appropriate to question these new readings of Marx which, if they can be fruitful, pose many problems, both philosophical and political.

Abstract
This article starts with a brief overview of the history of housing for people with intellectual disability in Austria. The system of care and Austrian disability policy are also examined, focusing on implementation of deinstitutionalisation and community living. The following analysis of services provided in the field of housing for people with intellectual disabilities shows that support is provided in undistinguished, generalised service packages based on a competency model. Academic research on community living is quite rare in Austria, and fails to take into account the subjective perspective of people with intellectual disabilities.
