Psychometric Validation of the Parental Bonding Instrument in a U.K. Population-Based Sample: Role of Gender and Association With Mental Health in Mid-Late Life.

The factorial structure of the Parental Bonding Instrument (PBI) has been frequently studied in diverse samples but no study has examined its psychometric properties from large, population-based samples. In particular, important questions have not been addressed such as the measurement invariance properties across parental and offspring gender. We evaluated the PBI based on responses from a large, representative population-based sample, using an exploratory structural equation modeling method appropriate for categorical data. Analysis revealed a three-factor structure representing "care," "overprotection," and "autonomy" parenting styles. In terms of psychometric measurement validity, our results supported the complete invariance of the PBI ratings across sons and daughters for their mothers and fathers. The PBI ratings were also robust in relation to personality and mental health status. In terms of predictive value, paternal care showed a protective effect on mental health at age 43 in sons. The PBI is a sound instrument for capturing perceived parenting styles, and is predictive of mental health in middle adulthood.Wellcome Trust (Grant ID: 088869/Z/09/Z)This is the author accepted manuscript.

Search for the standard model Higgs boson in the diphoton decay channel with 4.9fb -1 of pp collision data at √s=7TeV with atlas

A search for the standard model Higgs boson is performed in the diphoton decay channel. The data used correspond to an integrated luminosity of 4.9  fb-1 collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of √s=7  TeV. In the diphoton mass range 110–150 GeV, the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations. Taking the look-elsewhere effect into account in the range 110–150 GeV, this significance becomes 1.5 standard deviations. The standard model Higgs boson is excluded at 95% confidence level in the mass ranges of 113–115 GeV and 134.5–136 GeV

A Guide to Exploratory Structural Equation Modeling (ESEM) and Bifactor-ESEM in Body Image Research

Traditionally, assessments of factor validity of body image instruments have relied on exploratory or confirmatory factor analysis. However, the emergence of exploratory structural equation modeling (ESEM), a resurgence of interest in bifactor models, and the ability to combine both models (bifactor-ESEM) is beginning to shape the future of body image research. For these analytic approaches to truly advance body image research, scholars will need to have a deep understanding of their use and application. To facilitate such understanding, we describe ESEM and bifactor-ESEM models for body image researchers and provide them with the tools they need to apply these methods in their own work. Specifically, we provide an overview of ESEM and bifactor-ESEM models, and describe their broad applicability to body image research. Next, we describe how ESEM and bifactor models can be used and, using an existing dataset of responses to the Acceptance of Cosmetic Surgery Scale, demonstrate how ESEM and bifactor-ESEM models can be deployed. To facilitate wider application of these ideas, we provide our Mplus syntax (inputs) in Supplementary Materials. Through this manuscript, we hope to assist researchers to better understand the strengths ESEM and bifactor models, and to use these approaches in their own work.</p

On the nature, predictors, and outcomes of work passion profiles: A comparative study across samples of Indigenous and non-Indigenous Australian employees

Based on the dualistic model of passion, we conducted person-centered analyses to assess how harmonious and obsessive passion for work combine within distinct profiles of employees and document the associations between these profiles and theoretically relevant predictors and outcomes. We also investigate whether the nature of these profiles, and their associations with predictors and outcomes, differs between samples of Australian Indigenous ( N = 591; 66.0% female, M age = 41.87) and non-Indigenous ( N = 605; 56.0% female, M age = 44.79) employees. Our results uncovered four profiles, which were replicated across both samples of employees: Harmonious Passion Dominant, Obsessive Passion Dominant, Mixed Passion-Obsessive Passion Dominant, and Low Passion. Role ambiguity and job overload were found to be related to employees’ likelihood of profile membership in a way that was similar across both samples. Finally, psychological well-being and resilience at work differed as a function of profile membership in a way that was replicated across samples. In addition to the theoretical implications for research on work passion, these results clearly highlight how work passion has highly similar implications for Indigenous and non-Indigenous Australian employees.

School Leaders’ Self-Efficacy and Job Satisfaction Over Nine Annual Waves: A Substantive-Methodological Synergy Juxtaposing Competing Models of Directional Ordering

The school principal’s job is increasingly demanding and complex, but school-principal well-being is understudied. Self-efficacy and job satisfaction are critical constructs for studying school principals’ well-being, and self-efficacy is a core predictor of job satisfaction. Cross-sectional research typically assumes a unidirectional ordering; self-efficacy predicts (and leads to) job satisfaction, not the reverse. However, this unidirectional ordering is inconsistent with theoretical models positing a bidirectional (reciprocal) ordering. Furthermore, the assumption is largely untested with appropriate longitudinal data and statistical models. We evaluated the directional ordering of job satisfaction and self-efficacy for a large (N = 5663), nationally representative, longitudinal (nine annual waves) sample of Australian school leaders. Job satisfaction and self-efficacy were moderately correlated within waves and over time. Consistently with theoretical models and a priori predictions, the two constructs were reciprocally related over time; prior measures of each had small statistically positive effects on subsequent measures of the other, with no evidence of directional predominance of one over the other. Support for reciprocal effects was remarkably consistent across competing cross-lag-panel models, multiple tests of the consistency of effects over time (measurement invariance and stationarity), control for covariates, and the addition of lag-2 paths. Methodologically, we critique competing models that estimate cross-lagged effects and evaluate directional ordering from withinand between-person perspectives. We demonstrate the value of both approaches in achieving a robust framework for assessing longitudinal panel models.. Our substantive-methodological synergy has important substantive implications for theory, policy, and practice—showing that school-leader job satisfaction and selfefficacy are mutually reinforcing

Employee commitment before and after an economic crisis: A stringent test of profile similarity

© The Author(s) 2017. Researchers have recently begun to take a person-centered (profile) approach to investigate how the affective, normative and continuance commitment mindsets combine within the three-component model of organizational commitment. The meaningfulness of the profiles identified in this research depends, in part, on evidence that similar profiles emerge across samples, particularly those drawn from a common population. We conducted a particularly stringent test of similarity by comparing profiles for samples of employees drawn from a large Turkish conglomerate prior to (N = 346) and following (N = 797) a major economic crisis. Using procedures recently introduced by Morin et al., (2016) we found similarity in the number (seven) and structure of the profiles before and after the crisis; only the distribution of individuals across profiles (i.e. the relative size of the profiles) differed. We also found similarity in the patterns of relations with theoretical antecedent, correlate, and outcome variables, suggesting that a common set of principles might be operating regardless of major differences in the work environment. In addition to providing strong evidence for the meaningfulness of commitment profiles, this study is one of the first to investigate the impact of an economic crisis on employee commitment

Compound effect of EHD and surface roughness in pool boiling and CHF with R-123

This article is a post-print version of the fianl published article which may be accessed at the link below.Saturated pool boiling of R-123 at 1 bar, including the critical heat flux (CHF), was enhanced by modifying the surface characteristics and applying a high intensity electrostatic field, the latter termed electrohydrodynamic (and abbreviated EHD) enhancement. The heat flux was varied from very low values in the natural convection regime up to CHF. Experiments were performed with increasing and decreasing heat flux to study boiling hysteresis without and with EHD. Boiling occurred on the sand blasted surface of a cylindrical copper block with embedded electrical heating elements, with standardized surface parameter Pa = 3.5 μm. The electric field was generated by a potential of 5 kV to 25 kV, applied through a 40 mm diameter circular electrode of ss-304 wire mesh, aperture size 5.1 mm, located at distances of 5 - 60 mm from the surface, with most of the data obtained for 20 mm. The data for the rough surface were compared with earlier data for a smooth surface and indicated a significant increase in the heat transfer rates. EHD produced a further increase in the heat transfer rates, particularly at low heat flux values and near the CHF. Boiling hysteresis was reduced progressively by EHD and eliminated at high field strength.This work was supported by Government of Pakistan under a scholarship programme
