While recognizing the daunting task of defining universal indicators of job quality we may overlook something more fundamental: in North America about a third of people may not want to be employed in their current job status. Job status congruence (i.e. the extent to which people are working full-time, contract, or part-time by choice) may now be an integral part of high quality work. We test this proposition using a process-oriented theoretical model reflecting established relationships in the work design literature. Findings suggest that a socio-economic predictor (job status congruence) may rival established psychological predictors of job quality (e.g. intrinsic job characteristics and role stressors) in predicting aspects of workers’ personal and organizational functioning. Our findings also suggest that different mediators may be operating for each outcome. The model is tested on 171 full-time workers; a revised model is then supported on a holdout sample of 172 full-timers, and replicated on 132 contract/part-time workers using multi-group structural equation modeling. Implications for future research are discussed.
Instantaneous planar laser induced fluorescence (PLIF) images of OH, simultaneous axial/radial and axial/tangential velocity measurements with an LDA (laser Doppler anemometer), and instantaneous gas temperature measurements using a coherent anti-Stokes Raman spectrometer (CARS) were obtained in a pre-mixed, swirl-stabilized laboratory-scale combustor, fired with natural gas. Four operating conditions were examined (two swirl conditions and equivalence ratios of 0.80 and 0.65). The instantaneous PLIF images of OH illustrate the chaotic nature of the turbulent flame eddies. Mean and standard deviations of each variable were measured at different locations in the flame, along with probability density functions. Stability of the flame at each condition is related to measurements in the central and side recirculation zones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
