The Influence of Reflection on Employee Psychological Empowerment: Report of an Exploratory Workplace Field Study

ABSTRACT The study examined the influences of reflection on the self‐perception of empowerment in the workplace. The convenience sample consisted of non‐management knowledge workers at a software company headquartered in the United States. A pretest, posttest control group design was used. The experimental group kept guided journals of their learning activities for three months. Immediately prior to and following the journaling period, both groups completed Spreitzer's Psychological Empowerment Scale. Though no significant within‐group results were found, between‐group analyses revealed that participants who kept guided journals were able to maintain a high level of psychological empowerment, even during turbulent periods at the host organization, while the psychological empowerment of the control group worsened. The results suggest that reflection through guided journaling may sustain the perception of empowerment for individuals who already possess a fairly high level of psychological empowerment. The paper concludes with implications for further research.     

A prospective study of pedometer-determined physical activity and physical self-perceptions in children

There have been limited prospective studies investigating physical activity and physical self-perceptions in children. In this investigation, mean steps/day did not significantly change from late elementary to junior high for either boys or girls; however; boys accumulated more steps both at baseline and follow-up. Physical self-perception measures were significantly related to changes in steps/day and accounted for 21% (15% adjusted) of the variance after controlling for demographic/biological variables, R2 change = .21, adjusted R2 change = .15, F (5,88) = 4.66, p < .001. Sport competence emerged as the most important predictor t (88) = -3.76, p < .001, and was inversely related to physical activity change. The lack of opportunities to participate in sport activities normally found at the onset of adolescence may help explain this unexpected result.     

Mapping the biomedical sciences using Medical Subject Headings: a comparison between MeSH co-assignments and MeSH citation pairs

Objective:This study compares two maps of biomedical sciences using Medical Subject Headings (MeSH) term co-assignments versus MeSH terms of citing/cited articles and reveals similarities and differences between the two approaches.Methods:MeSH terms assigned to 397,475 journal articles published in 2015, as well as their 4,632,992 cited references, were retrieved from Web of Science and MEDLINE databases, respectively, which formed over 7 million MeSH co-assignments and nearly 18 million direct citation pairs. We generated six network visualizations of biomedical science at three levels using Gephi software based on these MeSH co-assignments and citation pairs.Results:The MeSH co-assignment map contained more nodes and edges, as MeSH co-assignments cover all medical topics discussed in articles. By contrast, the MeSH citation map contained fewer but larger nodes and wider edges, as citation links indicate connections to two similar medical topics.Conclusion:These two types of maps emphasize different aspects of biomedical sciences, with MeSH co-assignment maps focusing on the relationship between topics in different categories and MeSH direct citation maps providing insights into relationships between topics in the same or similar category.
