The association between Extraversion and well-being is limited to one facet.

ObjectiveMõttus argues that effects should not be attributed to traits if they are driven by particular facets or items. We apply this reasoning to investigate the relationship between facets and items of Extraversion and well-being.MethodWe analyzed five cross-sectional datasets (total N = 1,879), with facet- and item-level correlations and SEM.ResultsWe found that the correlation between the energy level facet and well-being was solely responsible for the association between Extraversion and well-being. Neither sociability nor assertiveness were uniquely related to well-being when energy level was included as a predictor. Thus, the correlations between well-being and sociability and between well-being and assertiveness can be almost fully explained by these constructs' relationships with energy level.ConclusionsWe conclude that the link between Extraversion and well-being should be attributed to the energy level facet rather than generalized to the trait level

Measuring eudaimonic and non-eudaimonic goods in the pursuit of the good life: The Riverside Eudaimonia Scale and the Rich & Sexy Well-Being Scale

Well-being science has largely focused on subjective well-being, defined in terms of life satisfaction and positive and negative emotions. However, some philosophical accounts of well-being, like “eudaimonia” accounts, emphasize the attainment of goods, such as having deep social relationships and achieving one’s creative potential. We supplement psychological measures of eudaimonia by developing two self-report measures of well-being informed by the philosophical literature. The Riverside Eudaimonia Scale (RES) was designed to measure people’s perceptions of their eudaimonic well-being along several dimensions emphasized in the philosophical literature on eudaimonia. The Rich & Sexy Well-Being Scale (RSWBS) was designed to measure people’s perceptions of their attainment of other commonly valued goods that have received less attention in the literature on eudaimonic well-being: sex life, wealth, personal physical beauty, and social status. In three studies, we develop and validate these scales

Clustering by well-being in workplace social networks: Homophily and social contagion.

Social interaction among employees is crucial at both an organizational and individual level. Demonstrating the value of recent methodological advances, 2 studies conducted in 2 workplaces and 2 countries sought to answer the following questions: (a) Do coworkers interact more with coworkers who have similar well-being? and, if yes, (b) what are the processes by which such affiliation occurs? Affiliation was assessed via 2 methodologies: a commonly used self-report measure (i.e., mutual nominations by coworkers) complemented by a behavioral measure (i.e., sociometric badges that track physical proximity and social interaction). We found that individuals who share similar levels of well-being (e.g., positive affect, life satisfaction, need satisfaction, and job satisfaction) were more likely to socialize with one another. Furthermore, time-lagged analyses suggested that clustering in need satisfaction arises from mutual attraction (homophily), whereas clustering in job satisfaction and organizational prosocial behavior results from emotional contagion. These results suggest ways in which organizations can physically and socially improve their workplace. (PsycINFO Database Recor

Empirical Relationships Among Five Types of Well-Being

Philosophers, psychologists, economists and other social scientists continue to debate the nature of human well-being. We argue that this debate centers around five main conceptualizations of well-being: hedonic well-being, life satisfaction, desire fulfillment, eudaimonia, and non-eudaimonic objective-list well-being. Each type of well-being is conceptually different, but are they empirically distinguishable? To address this question, we first developed and validated a measure of desire fulfillment, as no measure existed, and then examined associations between this new measure and several other well-being measures. In addition, we explored associations among all five types of well-being. We found high correlations among all measures of well-being, but generally correlations did not approach unity, even when correcting for unreliability. Furthermore, correlations between well-being and related constructs (e.g., demographics, personality) depended on the type of well-being measured. We conclude that empirical findings based on one type of well-being measure may not generalize to all types of well-being

Testing ultrafast mode-locking at microhertz relative optical linewidth

We report new limits on the phase coherence of the ultrafast mode-locking process in an octave-spanning Ti:sapphire comb. We find that the mode-locking mechanism correlates optical phase across a full optical octave with less than 2.5 micro Hz relative linewidth. This result is at least two orders of magnitude below recent predictions for quantum-limited individual comb-mode linewidths, verifying that the mode-locking mechanism strongly correlates quantum noise across the comb spectrum.Comment: Expanded discussion to include correlated noise terms, made minor formatting changes, added a reference, and fixed typographical errors. 10 pages, 5 figure

Current recommendations on the selection of measures for well-being

Measures of well-being have proliferated over the past decades. Very little guidance has been available as to which measures to use in what contexts. This paper provides a series of recommendations, based on the present state of knowledge and the existing measures available, of what measures might be preferred in which contexts. The recommendations came out of an interdisciplinary workshop on the measurement of well-being. The recommendations are shaped around the number of items that can be included in a survey, and also based on the differing potential contexts and purposes of data collection such as, for example, government surveys, or multi-use cohort studies, or studies specifically about psychological well-being. The recommendations are not intended to be definitive, but to stimulate discussion and refinement, and to provide guidance to those relatively new to the study of well-being

A Role for Cdc2- and PP2A-Mediated Regulation of Emi2 in the Maintenance of CSF Arrest

Vertebrate oocytes are arrested in metaphase II of meiosis prior to fertilization by cytostatic factor (CSF). CSF enforces a cell cycle arrest by inhibiting the anaphase promoting complex (APC), an E3 ubiquitin ligase that targets Cyclin B for degradation. Although Cyclin B synthesis is ongoing during CSF arrest, constant Cyclin B levels are maintained. To achieve this, oocytes allow continuous slow Cyclin B degradation, without eliminating the bulk of Cyclin B, which would induce release from CSF arrest. However, the mechanism that controls this continuous degradation is not understood

Reflections on the four facets of symmetry: how physics exemplifies rational thinking

In contemporary theoretical physics, the powerful notion of symmetry stands for a web of intricate meanings among which I identify four clusters associated with the notion of transformation, comprehension, invariance and projection. While their interrelations are examined closely, these four facets of symmetry are scrutinised one after the other in great detail. This decomposition allows us to examine closely the multiple different roles symmetry plays in many places in physics. Furthermore, some connections with others disciplines like neurobiology, epistemology, cognitive sciences and, not least, philosophy are proposed in an attempt to show that symmetry can be an organising principle also in these fields
