Using a gradation of openness in a (Chang fuzzy) I-topological space, we introduce degrees of compactness that we call α-fuzzy compactness (where α belongs to the unit interval), so extending the concept of compactness due to C. L. Chang. We obtain a Baire category theorem for α-locally compact spaces and construct a one-point α-fuzzy compactification of an I-topological space. 1. Introduction....

This paper presents a systematic analysis of the similarities and differences between the fields of open innovation and open strategy. In particular, we examine the concept of openness from a communication-centered perspective and compare processes of open innovation and open strategy with regard to the openness they exhibit. By distinguishing between openness in terms of sociality, factuality ...

BACKGROUND The differential susceptibility hypothesis states that some genetic variants that confer risk in adverse environments are beneficial in normal or nurturing environments. The cholinergic system is promising as a source of susceptibility genes because of its involvement in learning and neural plasticity. The cholinergic receptor gene CHRNA4 has been linked to characteristics related to...

With the introduction of quasimarket principles in the mid-1990s, the German social service sector faced several challenges from above (the state), within (the organizations), and outside (new competitors and “players”). Within the social services, considerable differences prevail between subsectors; although all reforms have been oriented at the principle of (quasi)markets, the governance arra...

In this paper, we present a procedure for organizing real world scenes along semantic axes. The approach is based on the output energies of linear discriminant filters that take into account, or not, spatial information. We introduce three semantic axes along which pictures are ordered. The main semantic axis computes the degree of naturalness of a scene. Then, urban pictures are evaluated acco...

Studies reveal a strong relationship between personality and preferred musical genre. Our study explored this relationship using a new methodology: genre dispersion among people’s mobile-phone music collections. By analyzing the download behaviours of genre-defined user subgroups, we investigated the following questions: (1) do genre-preferring subgroups show distinct patterns of genre consumpt...

This paper considers the question of economic nationalism through the lens of economic openness. Complete economic openness, which connotes close or total integration of a country with that of the world economy, is the antonym of economic nationalism. The paper argues that economic openness is a multi-dimensional concept. A country can be open, or not so open to all or some of the following: tr...

The psychedelic experience (including psychedelic-induced ego dissolution) can effect lasting change in a person's attitudes and beliefs. Here, we aimed to investigate the association between naturalistic psychedelic use and personality, political perspectives, and nature relatedness using an anonymous internet survey. Participants (N = 893) provided information about their naturalistic psyched...
