Protean career orientation has become prevalent among young workers in contemporary workplace. Little is known about whether this orientation is related to their positive expectation of future career development. We developed a conceptual model to investigate the relationship between protean career orientation and career optimism. Informed by social construction theory and social cognitive career theory, we considered career adaptability and career decision self-efficacy (CDSE) as potential mediators in the model. Several hypotheses were proposed and tested with a sample of 170 undergraduate students in Hong Kong. The results of path analysis and bootstrapping indicated that protean career orientation has a positive relationship with career optimism, and such relationship is fully mediated by career adaptability and CDSE. Our study has yielded novel into how some individual differences factors affect the development of career optimism among university students.
Several ack::Mu d1-8 insertions were isolated from Salmonella typhimurium on MacConkey-glucose-trimethylamine oxide medium. They could not produce gas from glucose in the absence of exogenous formate. Two of the mutants expressed beta-galactosidase activity and were shown to be ack::Mu d1-8 fusions by genetic analysis. These insertions were characterized and located on the genetic map at the ack locus by co-transduction with zei::Tn10. The gene order zei::Tn10-ack-pta was established. The direction of transcription of ack was clockwise on the genetic map. Expression of the lac operon in ack::Mu d1-8 was increased twofold by anaerobiosis. Addition of formate, pyruvate, and acetate did not affect the anaerobic expression of the lac operon in ack::Mu d1-8.
Future work self is a promising concept to understand how young people view and plan their careers in the contemporary workplace. In this study, we attempt to investigate its impacts on two career-related outcomes, namely, perceived employability and career distress. Informed by social cognitive career theory, we also explore the mediating role of career decision self-efficacy in the above relationships. Several hypotheses were developed and tested with a sample of 208 final-year undergraduate students (with a mean age of 21.5 and 145 of them are female) in China. The results of structural equation modeling and bootstrapping indicated that future work self has a positive relationship with perceived employability and a negative relationship with career distress, while these relationships are found to be mediated by career decision self-efficacy. Our study has advanced our understanding about how future work self contributes to career-related well-being among Chinese students.
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.
