The Idea of a Proof-Theoretic Semantics and the Meaning of the Logical Operations

This is a purely conceptual paper. It aims at presenting and putting into perspective the idea of a proof-theoretic semantics of the logical operations. The first section briefly surveys various semantic paradigms, and Section 2 focuses on one particular paradigm, namely the proof-theoretic semantics of the logical operations. This revised version was published online in June 2006 with corrections to the Cover Date.     

THE MANY FACES OF PANENTHEISM: AN EDITORIAL INTRODUCTION

A well‐known difficulty of the interdisciplinary dialogue beyond the limits of particular disciplines is the lack of common ground regarding their metaphysical and methodological assumptions and commitments. This is particularly evident for the precarious relationship between science and religion. In a 2016 conference entitled “The Many Faces of Panentheism” held in Zurich, and now in this introduction as well as this section, we try to counteract this situation by choosing a focus theme located at the interface between nature and the divine. Thus, key perspectives, arguments, and implications of panentheism are introduced not only from one selected point of view but in relation to others. This allows us to explore territory beyond the boundaries of disciplinary backgrounds and to address intellectual and practical consequences for current debates.     

The Ethical Challenges of the Digital Age

This article examines the ethical challenges of digital transformation in three steps. First, it offers a survey of the various dimensions of digital transformation and the ethical challenges that are associated with them: the exposure of private life through access to data; the change of communication culture through algorithms; the concentration of corporate power; changes in the world of work; the military use of digital technology; and the fusion of the human being and the machine. Second, it reflects upon various fundamental anthropological dimensions of the biblical tradition, which does not define humankind through itself but first and foremost in relation to, and being different from, God. Third, it draws conclusions about how to deal with digital transformation: through rescuing public discourse, making digital transformation socially accountable, and offering a perspective of theological anthropology that takes account of both the vulnerability and the deep freedom of our humanity.     

Investigating the Relationships Between Mobility Behaviours and Indicators of Subjective Well-Being Using Smartphone-Based Experience Sampling and GPS Tracking

People interact with their physical environments every day by visiting different places and moving between them. Such mobility behaviours likely influence and are influenced by people's subjective well-being. However, past research examining the links between mobility behaviours and well-being has been inconclusive. Here, we provide a comprehensive investigation of these relationships by examining individual differences in two types of mobility behaviours (movement patterns and places visited) and their relationship to six indicators of subjective well-being (depression, loneliness, anxiety, stress, affect, and energy) at two different temporal levels of analysis (two-week tendencies and daily level). Using data from a large smartphone-based longitudinal study (N = 1765), we show that (i) movement patterns assessed via GPS data (distance travelled, entropy, and irregularity) and (ii) places visited assessed via experience sampling reports (home, work, and social places) are associated with subjective well-being at the between and within person levels. Our findings suggest that distance travelled is related to anxiety, affect, and stress, irregularity is related to depression and loneliness, and spending time in social places is negatively associated with loneliness. We discuss the implications of our work and highlight directions for future research on the generalizability to other populations as well as the characteristics of places. © 2020 European Association of Personality Psychology

Visual timing abilities of a harbour seal (Phoca vitulina) and a South African fur seal (Arctocephalus pusillus pusillus) for sub- and supra-second time intervals

Animal Cognition - Timing is an essential parameter influencing many behaviours. A previous study demonstrated a high sensitivity of a phocid, the harbour seal (Phoca vitulina), in discriminating...     

Stimulus-response compatibility in intensity-force relations.

Romaiguère, Hasbroucq, Possama?, and Seal (1993) reported a new compatibility effect from a task that required responses of two different target force levels to stimuli of two different intensities. Reaction times were shorter when high and low stimulus intensities were mapped to strong and weak force presses respectively than when this mapping was reversed. We conducted six experiments to refine the interpretation of this effect. Experiments 1 to 4 demonstrated that the compatibility effect is clearly larger for auditory than for visual stimuli. Experiments 5 and 6 generalized this finding to a task where stimulus intensity was irrelevant. This modality difference refines Romaiguère et al.'s (1993) symbolic coding interpretation by showing that modality-specific codes underlie the intensity-force compatibility effect. Possible accounts in terms of differences in the representational mode and action effects are discussed.
