Current concepts of the management of dental extractions for patients taking warfarin

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.Background: Controversy has surrounded the correct management of patients therapeutically anticoagulated with warfarin who require dental extractions. The risk of bleeding must be weighed up against the risk of thromboembolism when deciding whether to interfere with a patient's warfarin regimen. An improved understanding of the importance of fibrinolytic mechanisms in the oral cavity has resulted in the development of various local measures to enable these patients to be treated on an outpatient basis. Methods: A review of the literature was undertaken. This was supplemented by the authors' clinical trials and extensive clinical experience with anticoagulated patients. Results: Various protocols for treating patients taking warfarin have been reviewed and summarized and an overview of the haemostatic and fibrinolytic systems is presented. A protocol for management of warfarinized patients requiring dental extractions in the outpatient setting is proposed. Conclusions: Patients therapeutically anticoagulated with warfarin can be treated on an ambulatory basis, without interruption of their warfarin regimen provided appropriate local measures are used.G Carter, AN Goss, JV Lloyd, R Tocchett

Prefix-Rewriting: the Falsification by Fellow Traveler Property and Practical Computation

The word problem is one of the fundamental areas of research in infinite group theory, and rewriting systems (including finite convergent rewriting systems, automatic structures, and autostackable structures) are key approaches to working on the word problem. In this dissertation, we discuss two approaches to creating bounded regular convergent prefix-rewriting systems. Groups with the falsification by fellow traveler property are known to have solvable word problem, but they are not known to be automatic or to have finite convergent rewriting systems. We show that groups with this geometric property are geodesically autostackable. As a key part of proving this, we show that a wider class of groups, namely groups with a weight non-increasing synchronously regular convergent prefix-rewriting system, have a bounded regular convergent prefix-rewriting system. Our second approach to creating prefix-rewriting systems is a more general approach. We design a procedure that, when provided with a finitely presented group G = ⟨A : R⟩ and an ordering \u3c on A∗ , searches for a bounded convergent prefix-rewriting system. We also create a class of orderings for which each step of this procedure can be practically computed, and which guarantees that any bounded convergent prefix-rewriting system is an autostackable structure

The relationship between retail store manager leadership styles and employee generational cohort, performance, and satisfaction

The aging and retirement of Baby Boomers has resulted in Generations X and Y becoming the dominant retail workplace generational cohorts. Retail stores employ a high percentage of younger workers as a portion of their overall workforce and will experience changes in worker needs as generations change. Understanding how different leadership techniques affect younger retail workers may provide an understanding for all industries, as younger generations become the dominant group within the national workforce. The goal of the quantitative research study was to examine any predictive relationships among associates’ generational cohort, their managers’ leadership styles, and outcome variables of productivity, tenure, employee extra effort, perceived manager effectiveness, and employee satisfaction. Two hundred fifty usable responses were collected using a sequential cluster and stratified method to allow for adequate participants from each generational cohort while achieving national geographical generalizability. Bivariate correlational analyses and multiple regression analyses were conducted to determine the relationship among predictor and outcome variables. All generations’ satisfaction measures and older generations’ sales productivity positively related with transformational leadership. Transformational leadership was found to be positively related with outcome variables across generational cohorts without instance of a negative relationship. Because most retailers would want to influence these outcome variables positively, management’s use of transformational leadership is encouraged

An investigation into effects of superior-subordinate similarity on performance ratings and rating discrepancy

The effect on performance ratings of superiorsubordinate similarity in background, interests, occupational values, job needs and personality was examined. The sample included 434 dyads from a total of 84 professional employees, 16 of whom were in supervisory positions. Three primary research questions posed by the present study included: (1) Is the similarity effect an artifact of simpler rater and ratee effects? (2) What is a more appropriate dependent measure—performance rating or deviation of rating from the mean of non- dyadic raters, i.e., discrepancy? (3) Does superior familiarity with subordinate performance moderate similarity effects? Results from hierarchical multiple regression analyses provided compelling evidence that the direct relationship between similarity and performance criteria could be an artifact of rater leniency and ratee scores on similarity scales. This finding brings into question the conclusions of previous researchers. With regard to the second research question, data from this study did not support an argument for preference of either dependent measure over the other. Finally, it was found that familiarity moderated the similarity effect for values. It appears that as familiarity increases, similarity in values becomes more predictive of performance criteria.Psychology, Department o
