16. Children's Tendency to Defend Victims of School Bullying

Author

Porter, James R. and Smith-Adcock, Sondra

Abstract

Defenders, or children who help victims, are studied less often than children who bully or are victims of bullying. In this study, the authors examined middle schools students' perceived normative pressure from significant others to help victims. Findings suggest that normative pressure from best friends mediated gender and defending, and the interaction of age and best friends' pressure was significantly related to defending. The article suggests implications for bullying prevention in middle schools.

29. Children Who Help Victims of Bullying: Implications for Practice

Author

Porter, James R. and Smith-Adcock, Sondra

Abstract

Over the years, literature on the phenomenon of bullying has evolved from treating bullying as an individual behavior to understanding it as a group process. Other than those of the bully and the victim, researchers have identified several roles children assume in bullying situations, with some assuming a pro-social role, often called the "defender," in bullying scenarios. Practice literature continues to concentrate its attention narrowly on the bully and the victim, rather than on defenders. Understanding the individual and social circumstances related to defending suggests new avenues for practitioners interested in promoting improved peer relations in schools.

Abstract

Introduction: Outcomes of robot-assisted partial nephrectomy (RAPN) depend on tumor complexity, surgeon experience and patient profile among other variables. We aimed to study the perioperative outcomes of RAPN for patients with complex renal masses using the Vattikuti Collective Quality Initiative (VCQI) database that allowed evaluation of multinational data. Methods: From the VCQI, we extracted data for all the patients who underwent RAPN with preoperative aspects and dimensions used for an anatomical (PADUA) score of >= 10. Multivariate logistic regression was conducted to ascertain predictors of trifecta (absence of complications, negative surgical margins, and warm ischemia times {[}WIT] = 10 were included. The median operative time, WIT, and blood loss were 173 (range 45-546) min, 21 (range 0-55) min, and 150 (range 50-3500) ml, respectively. Intraoperative complications and blood transfusions were reported in 2.1\% and 6\%, respectively. In 8.8\% of the patients, postoperative complications were noted, and surgical margins were positive in 10.3\% of the patients. Trifecta could be achieved in 60.7\% of patients. Clinical tumor size, duration of surgery, WIT, and complication rates were significantly higher in the group with a high (12 or 13) PADUA score while the trifecta was significantly lower in this group (48.4\%). On multivariate analysis, surgical approach (retroperitoneal vs. transperitoneal) and high PADUA score (12/13) were identified as predictors of the trifecta outcomes. Conclusion: RAPN may be a reasonable surgical option for patients with complex renal masses with acceptable perioperative outcomes.

Abstract

To predict intra-operative (IOEs) and postoperative events (POEs) consequential to the derailment of the ideal clinical course of patient recovery.The Vattikuti Collective Quality Initiative is a multi-institutional dataset of patients who underwent robot-assisted partial nephectomy for kidney tumours. Machine-learning (ML) models were constructed to predict IOEs and POEs using logistic regression, random forest and neural networks. The models to predict IOEs used patient demographics and preoperative data. In addition to these, intra-operative data were used to predict POEs. Performance on the test dataset was assessed using area under the receiver-operating characteristic curve (AUC-ROC) and area under the precision-recall curve (PR-AUC).The rates of IOEs and POEs were 5.62% and 20.98%, respectively. Models for predicting IOEs were constructed using data from 1690 patients and 38 variables; the best model had an AUC-ROC of 0.858 (95% confidence interval [CI] 0.762, 0.936) and a PR-AUC of 0.590 (95% CI 0.400, 0.759). Models for predicting POEs were trained using data from 1406 patients and 59 variables; the best model had an AUC-ROC of 0.875 (95% CI 0.834, 0.913) and a PR-AUC 0.706 (95% CI, 0.610, 0.790).The performance of the ML models in the present study was encouraging. Further validation in a multi-institutional clinical setting with larger datasets would be necessary to establish their clinical value. ML models can be used to predict significant events during and after surgery with good accuracy, paving the way for application in clinical practice to predict and intervene at an opportune time to avert complications and improve patient outcomes.

Abstract

Intramolecular cycloadditions between cyclobutadiene and olefins can provide highly functionalized cyclobutene-containing products. Successful intramolecular reactions usually require either electronic activation of the dienophile, conformational restriction of the tether, or a slower oxidation protocol.
