Vessel Dissection

This study describes the surgical technique and intra- and postoperative complications associated with the use of a radiofrequency bipolar coagulator in a series of 18 Piver type III-IV radical hysterectomies performed in cervical cancer patients. Preliminary vessel-by-vessel dissection of the lateral parametria was possible in 17 out of 18 (94%) cases, and a direct application of a radiofrequency bipolar coagulation instrument was performed to coagulate the posterior and anterior parametrial tissues in all cases. We were able to easily coagulate isolated vessels up to 5 mm of maximal diameter. In no case were clamps or hemoclips necessary to complete hemostasis. We did not observe any parametrial vessel damage or heat-related injury of the surrounding normal tissue. The median size of the parametria removed was 44 mm (range 31–58) and nodes were detected in 15 cases (83%). Median operative time and estimated blood loss for the whole procedure including systematic pelvic and aortic lymphadenectomy was 250 min (range 200–410) and 550 ml (range 400–2500), respectively. Median follow-up time was 9 months (range 5–13). No complications specifically related to the use of radiofrequency coagulation were found. In conclusion the radio-frequency coagulation with this instrument appears to be a safe technique that is particularly useful in reducing blood loss and operative time without affecting radicality in patients undergoing radical hysterectomy.

Abstract. We describe the development and validation of an instrument for measuring the affective component of primary school teachers’ attitudes towards self-regulated learning. The questionnaire assesses the affective component towards those cognitive and metacognitive strategies that are especially effective in primary school. In a first study (n = 230), the factor structure was verified via an exploratory factor analysis. A confirmatory factor analysis with data from a second study (n = 400) indicated that the theoretical factor structure is appropriate. A comparison with four alternative models identified the theoretically derived factor structure as the most appropriate. Concurrent validity was demonstrated by correlations with a scale that measures the degree to which teachers create learning environments that enable students to self-regulate their learning. Retrospective validity was demonstrated by correlations with a scale that measures teachers’ experiences with self-regulated learning. In a third study (n = 47), the scale’s concurrent validity was tested with scales measuring teachers’ evaluation of the desirability of different aspects of self-regulated learning in class. Additionally, predictive validity was demonstrated via a binary logistic regression, with teachers attitudes as predictor on their registration for a workshop on self-regulated learning and their willingness to implement a seven-week training program on self-regulated learning.

Development And Validation

Abstract. The current paper presents the development and validation of a unit-level Organizational Citizenship Behavior (OCB) scale based on the Referent-Shift Consensus Model (RSCM). In Study 1, with 124 individuals measured twice, both an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA) established and confirmed a five-factor solution (helping behavior, sportsmanship, loyalty, civic virtue, and conscientiousness). Test–retest reliabilities at a 2-month interval were high (between .59 and .79 for the subscales, .83 for the total scale). In Study 2, unit-level OCB was analyzed in a sample of 129 work teams. Both Interrater Reliability (IRR) measures and Interrater Agreement (IRA) values provided support for RSCM requirements. Finally, unit-level OCB was associated with group task interdependence and was more predictable (by job satisfaction and integrity of the supervisor) than individual-level OCB in previous research.
