The relationship between online vigilance and affective well-being in everyday life: Combining smartphone logging with experience sampling

2021

Contains fulltext : 220301.pdf (Publisher’s version ) (Open Access) Through communication technology, users find themselves constantly connected to others to such an extent that they routinely develop a mindset of connectedness. This mindset has been defined as online vigilance. Although there is a large body of research on media use and well-being, the question of how online vigilance impacts well-being remains unanswered. In this preregistered study, we combine experience sampling and smartphone logging to address the relation of online vigilance and affective well-being in everyday life. Seventy-five Android users answered eight daily surveys over five days (N = 1615) whilst having their…

Topological Logics with Connectedness over Euclidean Spaces

2013

We consider the quantifier-free languages, Bc and Bc °, obtained by augmenting the signature of Boolean algebras with a unary predicate representing, respectively, the property of being connected, and the property of having a connected interior. These languages are interpreted over the regular closed sets of R n ( n ≥ 2) and, additionally, over the regular closed semilinear sets of R n . The resulting logics are examples of formalisms that have recently been proposed in the Artificial Intelligence literature under the rubric Qualitative Spatial Reasoning. We prove that the satisfiability problem for Bc is undecidable over the regular closed semilinear sets in all dimensions greater than 1,…

Time and frequency dynamics of connectedness between renewable energy stocks and crude oil prices

2018

Abstract This paper examines the time and frequency dynamics of connectedness among stock prices of U.S. clean energy companies, crude oil prices and a number of key financial variables using the methodology developed by Barunik and Krehlik (2018). This approach allows measuring the dynamics of return and volatility connectedness over time and across frequencies simultaneously. The empirical results show that most of return and volatility connectedness is generated in the very short-term, i.e. movements up to five days, while the long-term plays a minor role. Our analysis further reveals a greater degree of interconnectedness across crude oil and financial markets since the onset of the U.S…

Orientation-Dependent Handedness of Chiral Plasmons on Nanosphere Dimers: How to Turn a Right Hand into a Left Hand

2016

Optical activity, which is used as a discriminator of chiral enantiomers, is demonstrated to be orientation dependent on individual, and nominally achiral, plasmonic nanosphere dimers. Through measurements of their giant Raman optical activity, we demonstrate that L/R-handed enantiomers can be continuously turned into their R/L-handed mirror images without passing through an achiral state. The primitive uniaxial multipolar response, with demonstrable broken parity and time reversal symmetry, reproduces the observations as resonant Raman scattering on plasmons that carry angular momentum. The analysis underscores that chirality does not have a quantitative continuous measure and recognizes t…

Auditory Phenomena and Human Life: Phenomenological Experience

2018

The present study analyzes auditory phenomena from the point of view of hermeneutical phenomenology and shows their interconnectedness with the understanding of man, hearing and listening within the context of human life as the horizon of meaningful sonority and silence. The central questions to be answered in this study are these: What is experienced as sound and sonority? How does a human see himself in inclusion of his being from where he listens, understands, and speaks? The study explores the classical standpoints of Husserl’s phenomenology and other philosophical apprehensions which confirm that auditory phenomena is not to be apprehended solely as an isolated horizon but as being per…

Measuring Globalization of International Trade: Theory and Evidence

2009

Measuring globalization requires a Standard of Perfect International Integration as a benchmark that a single world space would reach under conditions of geographic neutrality in international trade. We define this standard and present indicators for openness, connectedness and integration, for each specific economy, and for the world economy. We apply our indicators to data on trade flows for 59 countries for the 1967-2004 period. Results show that trade integration is higher than what traditional openness indicators suggest. Several economies find high levels of integration, but the low degree of openness in some large economies jeopardizes the progress of globalization. © 2008 Elsevier L…

Living with an adult family member using advanced medical technology at home

2011

Living with an adult family member using advanced medical technology at home An increased number of chronically ill adults perform self-care while using different sorts of advanced medical technology at home. This hermeneutical study aimed to gain a deeper understanding of the meaning of living with an adult family member using advanced medical technology at home. Eleven next of kin to adults performing self-care at home, either using long-term oxygen from a cylinder or ventilator, or performing peritoneal or haemodialysis, were interviewed. The qualitative interviews were analysed using a Gadamerian methodology. The main interpretation explained the meaning as rhythmical patterns of connec…

Volatility risk premia and financial connectedness

2014

In this paper we use the Diebold Yilmaz (2009 and 2012) methodology to construct an index of connectedness among five European stock markets: France, Germany, UK, Switzerland and the Netherlands, by using volatility risk premia. The volatility risk premium, which is a proxy of risk aversion, is measured by the difference between the implied volatility and expected realized volatility of the stock market for next month. While Diebold and Yilmaz focus is on the forecast error variance decomposition of stock returns or range based volatilities employing a stationary VAR in levels, we account for the (locally) long memory stationary properties of the levels of volatility risk premia series. The…

Subjectivation, togetherness, environment. Potentials of participatory art for Art Education for Sustainable Development (AESD)

2017

Through a process-oriented analysis of the participatory art project The Hill this article explores the relevance of participatory art projects for the development of AESD – Art Education for Sustainable Development. Inspired by Felix Guattari’s Three Ecologies (2008) the analysis moves through three sub-studies delving into three different aspects of the project. Each sub-study adopts two overlapping analytical ‘lenses’: The lens of a contemporary art form (performance art, community art, and site-specific art) and the lens of a related theoretical concept (subjectivation, togetherness, environment). The aim is to propose art educational ideas and strategies that stimulate students to chal…
