    Sociability is a widely studied trait that has been linked both with individual well-and ill-being. Although early childcare has been shown to affect social competence in children, its role in the development of different aspects of adulthood sociability is poorly understood. Using a longitudinal population-based sample (N = 464), this study investigated whether childcare arrangements at ages 3 or 6 are associated with self-reported adulthood sociability at ages 20 to 35 years. A total of five aspects of sociability were measured using three well-established personality inventories (EAS, NEO-FFI, and TCI). Multilevel modeling was applied to examine the association between early care and adulthood sociability, adjusting for several sources of random variation (between-individual variance, within-individual variance between measurement times, variance between used sociability indicators, and error variance that cannot be attributed to the previously mentioned) and potential confounders (disruptive behavior in childhood, parental socio-economic status, parent-child relationship quality, maternal age, and the number of children in the family). Based on our results, in comparison to home care, family daycare and center-based daycare at age 3 and center-based daycare at age 6 were associated with higher sociability later in life. The association was strongest for aspects of sociability that emphasize the willingness to be surrounded by other people and to be attached to them. In other words, characteristics of early care may contribute uniquely to the development of these aspects of sociability with effects that persist into adult life

    The current study examines the contribution of left-right (or liberal-conservative) ideology to voting, as well as the extent to which basic values account for ideological orientation. Analyses were conducted in 16 countries from five continents (Europe, North America, South America, Asia, and Oceania), most of which have been neglected by previous studies. Results showed that left-right (or liberal-conservative) ideology predicted voting in all countries except Ukraine. Basic values exerted a considerable effect in predicting ideology in most countries, especially in established democracies such as Australia, Finland, Italy, United Kingdom, and Germany. Pattern of relations with the whole set of 10 values revealed that the critical trade-off underlying ideology is between values concerned with tolerance and protection for the welfare of all people (universalism) versus values concerned with preserving the social order and status quo (security). A noteworthy exception was found in European postcommunist countries, where relations of values with ideology were small (Poland) or near to zero (Ukraine, Slovakia).

    This paper develops a theoretical argument for how place attachments are forged and become dynamically linked to increasingly common mobility practices. First, we argue that mobilities, rather than negating the importance of place, shift our understanding of place and the habitual ways we relate to and bond with places as distinct from a conception of place attachment premised on fixity and stability. Second, we document how the body of research on place attachment has both reinforced and contested 'sedentaristic' assumptions criticized within the so-called 'mobilities turn' in the social sciences. Third, we present a conceptual framework, built around different modes of interrelation between fixity and flow, as a way to re-theorize, link and balance the various studies of place attachment that have grappled with mobility. Finally, we sketch out the main research implications of this framework for advancing our understanding of place attachment in a mobile world.

    It has been conjectured that the speed of sound in holographic models with UV fixed points has an upper bound set by the value of the quantity in conformal field theory. If true, this would set stringent constraints for the presence of strongly coupled quark matter in the cores of physical neutron stars, as the existence of two-solar-mass stars appears to demand a very stiff equation of state. In this article, we present a family of counterexamples to the speed of sound conjecture, consisting of strongly coupled theories at finite density. The theories we consider include N = 4 super Yang-Mills at finite R-charge density and nonzero gaugino masses, while the holographic duals are Einstein-Maxwell theories with a minimally coupled scalar in a charged black hole geometry. We show that for a small breaking of conformal invariance, the speed of sound approaches the conformal value from above at large chemical potentials.

    Motivated by the topological classification of hamiltonians in condensed matter physics (topological insulators) we study the relations between chiral Dirac operators coupled to an abelian vector potential on a torus in 3 and 1 space dimensions. We find that a large class of these hamiltonians in three dimensions is equivalent, in K theory, to a family of hamiltonians in just one space dimension but with a different abelian gauge group. The moduli space of U(1) gauge connections over a torus with a fixed Chern class is again a torus up to a homotopy. Gerbes over a n-torus can be realized in terms of extensions of the lattice group acting in a real vector space. The extension comes from the action of the lattice group (thought of as "large" gauge transformations, homomorphisms from the torus to U(1)) in the Fock space of chiral fermions. Interestingly, the K theoretic classification of Dirac operators coupled to vector potentials in this setting in 3 dimensions can be related to families of Dirac operators on a circle with gauge group the 3-torus.

    This study identifies and analyses the underlying assumptions of experts involved in the first author meeting (FAM) of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)’s Values Assessment, and how they shape understandings of the multiple values of nature. We draw from survey data collected from 94 experts attending the FAM. Respondents self-report the tendencies and aims they bring to the assessment (i.e. motivation), the type and amount of evidence they require for knowledge to be valid (i.e. confirmation) and their epistemic worldviews (i.e. objectivity). Four clusters emerged that correspond to Pragmatist, Post-Positivist, Constructivist and Transformative epistemic worldviews. This result clarifies how different knowledge claims are represented in science-policy processes. Despite the proportionately higher number of social scientists in the Values Assessment, compared with previous IPBES assessments, we still found that fewer experts have Constructivist or Transformative worldviews than Pragmatist or Post-Positivist outlooks, an imbalance that may influence the types of values and valuation perspectives emphasised in the assessment. We also detected a tension regarding what constitutes valid knowledge between Post-Positivists, who emphasised high levels of agreement, and Pragmatists and Constructivists, who did not necessarily consider agreement crucial. Conversely, Post-Positivists did not align with relational values and were more diverse in their views regarding definitions of multiple values of nature compared to other clusters. Pragmatists emphasized relational values, while Constructivists tended to consider all value types (including relational values) as important. We discuss the implications of our findings for future design and delivery of IPBES processes and interdisciplinary research.

    We have collected a large dataset of subjective image quality "*nesses," such as sharpness or colorfulness. The dataset comes from seven studies and contains 39,415 quotations from 146 observers who have evaluated 62 scenes either in print images or on display. We analyzed the subjective evaluations and formed a hierarchical image quality attribute lexicon for *nesses, which is visualized as image quality wheel (IQ-Wheel). Similar wheel diagrams for attributes have become industry standards in other sensory experience fields such as flavor and fragrance sciences. The IQ-Wheel contains the frequency information of 68 attributes relating to image quality. Only 20% of the attributes were positive, which agrees with previous findings showing a preference for negative attributes in image quality evaluation. Our results also show that excluding physical attributes of paper gloss, observers then use similar terminology when evaluating images with printed images or images viewed on a display. IQ-Wheel can be used to guide the selection of scenes and distortions when designing subjective experimental setups and creating image databases. (C) 2019 SPIE and IS&T

    Background: Excessive stress has a negative impact on many aspects of life for both individuals and societies, from studying and working to health and well-being. Each individual has their unique level of stress-proneness, and positive or negative outcomes of stress may be affected by it. Technology-aided interventions have potential efficacy in the self-management of stress. However, current Web-based or mobile stress management solutions may not reach the individuals that would need them the most, that is, stress-sensitive people. Objective: The aim of this study was to examine how personality is associated with stress among Finnish university students and their interest to use apps that help in managing stress. Methods: We used 2 structured online questionnaires (combined, n=1001) that were advertised in the University of Helsinki's mailing lists. The first questionnaire (n=635) was used to investigate intercorrelations between the Big Five personality variables (neuroticism, extraversion, openness, agreeableness, and conscientiousness) and other stress-related background variables. The second questionnaire (n=366) was used to study intercorrelations between the above-mentioned study variables and interest in using stress management apps. Results: The quantitative findings of the first questionnaire showed that higher levels of extraversion, agreeableness, and conscientiousness were associated with lower self-reported stress. Neuroticism, in turn, was found to be strongly associated with rumination, anxiety, and depression. The findings of the second questionnaire indicated that individuals characterized by the Big Five personality traits of neuroticism and agreeableness were particularly interested to use stress management apps (r=.27, P Conclusions: Our results indicated that personality traits may have an influence on the adoption interest of stress management apps. Individuals with high neuroticism are, according to our results, adaptive in the sense that they are interested in using stress management apps that may benefit them. On the contrary, low agreeableness may lead to lower interest to use the mobile stress management apps. The practical implication is that future mobile stress interventions should meaningfully be adjusted to improve user engagement and support health even among less-motivated users, for instance, to successfully engage individuals with low agreeableness.

    Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality inventories were harmonized across inventories and cohorts. No genome-wide significant associations were found at the single nucleotide polymorphism (SNP) level but there was one significant hit at the gene level for a long non-coding RNA site (LOC101928162). Genome-wide complex trait analysis in two large cohorts showed that the additive variance explained by common SNPs was not significantly different from zero, but polygenic risk scores, weighted using linkage information, significantly predicted extraversion scores in an independent cohort. These results show that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits. Future studies are required to further determine which genetic variants, by what modes of gene action, constitute the heritable nature of extraversion.

    Aesthetic qualifies of urban green and blue spaces have received considerable attention in scientific literature but are operationalized in multiple ways and lack clear assessment and measurement techniques. To fill in this gap, we developed a Perceived Environmental Aesthetic Qualifies Scale (PEAQS). Based on previous literature both in philosophy and empirical sciences we created a questionnaire with 36 statements and three open questions focusing on the perceived aesthetic qualifies of environments. This questionnaire was used to sample 331 respondents in three sites different in their level of naturalness, human intervention and design: a natural-like but managed urban forest, a partly human-made and intensively managed bay-park and a completely human-made green roof. These sites were selected to represent a variety of urban green and blue infrastructure common in cities. The results suggest a scale that consists of 23 statements and five factors that reflect perceived aesthetic qualifies of urban green spaces: Harmony, Mystery, Multisensority & Nature, Visual Spaciousness and Visual Diversity, and Sublimity. We give guidelines for further development and testing of the scale in order to prove its potential to develop the field of environmental aesthetics and to demonstrate its usefulness for adaptive, evidence-based urban planning and design.

    We examined the association of perfectionism with depressive symptoms and tested whether psychological detachment from work would both mediate and moderate the association. The participants were 76 primary school teachers (87% female) who responded to measures of perfectionism (Multidimensional Inventory on Perfectionism in Sports adapted for teachers), psychological detachment from work (The Recovery Experience Questionnaire), and depressive symptoms (Beck Depression Inventory-II). Perfectionism comprised both adaptive and maladaptive dimensions. Adaptive perfectionism referred to striving for perfection, whereas maladaptive perfectionism involved negative reactions to imperfection and perceived pressure to be perfect. According to our results, negative reactions to imperfection were associated with higher depressive symptoms, and lower level of psychological detachment from work played a minor mediating role in the association. There was, however, no association between negative reactions to imperfection and higher depressive symptoms when detachment from work was high. Our findings suggest that striving for perfection and perceived pressure to be perfect might not contribute to depressive symptoms in teaching. Instead, teachers experiencing negative reactions to imperfection and low psychological detachment from work could be at risk for developing depressive symptoms. Finding ways to psychologically detach from work may benefit teachers characterized by negative reactions to imperfection. (C) 2017 Elsevier Ltd. All rights reserved.

    This study examined the association between five-factor model personality traits and perceptions of organisational justice. The sample for the study comprised 903 participants (35-50 years old; 523 women) studied in 2007 and 2012. Measures used were the Neuroticism, Extraversion, Openness, Five-Factor Inventory questionnaire and the short organisational justice measure. The results showed that high neuroticism was associated with low distributive, procedural and interactional justice. Furthermore, high agreeableness was associated with high procedural and interactional justice and high openness with high distributive justice. This study suggests that neuroticism, agreeableness and openness are involved in perceptions of organisational justice and that personality should be considered in research and in practices at the workplace.

    We consider the Higgs-radion mixing in the context of warped space extradimensional models with custodial symmetry and investigate the prospects of detecting the mixed radion. Custodial symmetries allow the Kaluza-Klein excitations to be lighter and protect Zbb to be in agreement with experimental constraints. We perform a complementary study of discovery reaches of the Higgs-radion mixed state at the 13 and 14 TeV LHC and at the 500 and 1000 GeV International Linear Collider (ILC). We carry out a comprehensive analysis of the most significant production and decay modes of the mixed radion in the 80 GeV-1 TeV mass range and indicate the parameter space that can be probed at the LHC and the ILC. There exists a region of the parameter space which can be probed, at the LHC, through the diphoton channel even for a relatively low luminosity of 50 fb(-1). The reach of the four-lepton final state in probing the parameter space is also studied in the context of 14 TeV LHC, for a luminosity of 1000 fb(-1). At the ILC, with an integrated luminosity of 500 fb(-1), we analyze the Z-radion associated production and the WW fusion production, followed by the radion decay into b (b) over bar and W+W-. The WW fusion production is favored over the Z-radion associated channel in probing regions of the parameter space beyond the LHC reach. The complementary study at the LHC and the ILC is useful both for the discovery of the radion and the understanding of its mixing sector.

    Spousal similarity and its consequences are widely studied, but methodologically challenging topics. We employed Response Surface Analysis to examine similarity along political attitudes, personal values, and personality traits. Opposite-sex couples (624 individuals) expecting a child were recruited. Spouses were highly similar regarding their political attitudes and moderately similar regarding trait Openness and the personal values Universalism and Tradition. Similarity for other traits and values was weak (e.g. Conscientiousness, Power values) or non-existent (e.g. Neuroticism, Benevolence values). Similarity in conservative vs. liberal attitudes was non-linear: a conservative-conservative union was most common. Women's relationship satisfaction was related to similarity in left-right and liberal-conservative political attitudes, and both partners' satisfaction was related to similarity in Self-Direction values. Similarity in personality traits was unrelated to relationship satisfaction.

    A search for heavy resonances decaying to a pair of Z bosons is performed using data collected with the CMS detector at the LHC. Events are selected by requiring two oppositely charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum, which is interpreted as arising from the decay of a second Z boson to two neutrinos. The analysis uses data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1). The hypothesis of a spin-2 bulk graviton (X) decaying to a pair of Z bosons is examined for 600 ZZ ranging from 100 to 4 fb. For bulk graviton models characterized by a curvature scale parameter (k) over tilde = 0.5 in the extra dimension, the region nix <800 GeV is excluded, providing the most stringent limit reported to date. Variations of the model considering the possibility of a wide resonance produced exclusively via gluon-gluon fusion or q annihilation are also examined.

    Previous studies on tactile experiences have investigated a wide range of material surfaces across various skin sites of the human body in self-touch or other touch modes. Here, we investigate whether the sensory and emotional aspects of touch are related when evaluating wooden surfaces using fingertips in the absence of other sensory modalities. Twenty participants evaluated eight different pine and oak wood surfaces, using sensory and emotional touch descriptors, through the lateral motion of active fingertip exploration. The data showed that natural and smooth wood surfaces were perceived more positively in emotional touch than coated surfaces. We highlight the importance of preserving the naturalness of the surface texture in the process of wood-surface treatment so as to improve positive touch experiences, as well as avoid negative ones. We argue that the results may offer possibilities in the design of wood-based interior products with a view to improving consumer touch experiences.

    Teacher educators' approaches to teaching, and their experience of burnout and self-efficacy beliefs, are related to how they are able to facilitate student teachers' learning. In this study, 115 Chinese teacher educators responded to a questionnaire in 2015. Based on the previous study investigating the teacher educators' approaches to teaching, the present study explored how these approaches were related to their self-efficacy beliefs in teaching and burnout. Burnout was measured through inadequacy in teacher-student interaction and exhaustion subscales. The analyses revealed that a student-focused approach to teaching among teacher educators was positively related to their self-efficacy beliefs in teaching. Both student- and teacher-focused approaches to teaching were positively related to the educators' experience of inadequacy in teacher-student interaction. However, the study revealed no relationship between teacher educators' approaches to teaching and the experience of exhaustion. To prevent feelings of inadequate interaction with their students, pedagogical training should provide these teacher educators with efficient guidance on how to interact with student teachers. The present study provides new insights in the teacher educators' adoption of the student- and teacher-focused approaches to teaching.
