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

Vincent L. Cyboran 《Performance Improvement Quarterly》2005,18(4):37-49

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.  相似文献   

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

Morgan CF  Graser SV  Pangrazi RP 《Research quarterly for exercise and sport》2008,79(2):133-140

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.  相似文献   

Water-repellent and biocide treatments: Assessment of the potential combinations   总被引：1，自引：0，他引：1

It is a common practice to use several chemical products during restoration projects of monuments or sculptures. However, care must be taken when combining the products to avoid a misuse. For example, it is well-known that applying a biocide on stone before a water-repellent leads to a diminishment of the hydrophobic effect of the treatment. But the application of biocide after a water-repellent treatment has been poorly analysed, although studies have proven that the stone looses its hydrophobicity after the application of the biocide. Henceforth, this study investigates the effects of biocide application on a water-repellent film and focuses on the possibilities to restore the efficiency of the previous water-repellent treatment (after the application of the biocide). At first, the tests were performed on glass slides to understand the mechanisms, with the subsequent results revealing that the biocide product deposits on the water-repellent film. Then, the study focuses on determining methods to remove the remains of biocide on limestone samples, previously treated with a water-repellent. The water-repellent used in the study is an alkylpolysiloxane, Rhodorsil H224 from Rhodia.  相似文献

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

Fei Shu  Junping Qiu  Vincent Larivire 《Journal of the Medical Library Association》2021,109(3):441

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.  相似文献

随机扩增多态性DNA技术研究发现二氧化钛纳米颗粒对西葫芦具有基因毒性     

Fabiola MORENO-OLIVAS  ;Vincent U.GANT Jr  ;Kyle L.JOHNSON  ;Jose R.PERALTA-VIDEA  ;Jorge L.GARDEA-TORRESDEY 《浙江大学学报(A卷英文版)》2014,15(8):618-623

研究目的：二氧化钛（TiO2）纳米颗粒已经广泛应用于化妆品、防晒霜、涂料和牙膏等。这些纳米颗粒性质非常稳定,能在废水和生物固体中转移和分散。现有研究表明,TiO2纳米颗粒对动物正常生理活动具有毒性等负面作用。但是,它们对植物是否具有毒性特别是是否会产生植物基因毒性至今尚不清楚。因此,本文使用随机扩增多态性DNA技术研究TiO2纳米颗粒是否对西葫芦具有基因毒性,为TiO2纳米颗粒排放进入环境后的潜在植物毒性风险评价提供依据。 创新要点：首次发现了TiO2纳米颗粒对西葫芦具有基因毒性。 重要结论：采用随机扩增多态性DNA技术,发现TiO2纳米颗粒污染处理的西葫芦样品与未处理样品的基因组DNA图谱相比,不仅在谱带强度有明显差异,而且存在谱带消失和新谱带产生现象,表明TiO2纳米颗粒对西葫芦具有基因毒性。  相似文献
