How black faculty experience presenting their research in educational venues within the context of historical objectification of black people as sources of entertainment is an underexplored topic in higher education research. Presenting research has far-reaching implications for black academics’ advancement, such as future employment and opportunities for research collaboration. Thus, how black faculty are perceived while presenting has significant implications for their career trajectories. This study is concerned with understanding how black higher education faculty perceive, interpret, and respond to how they are perceived while presenting within a context of racialized academic scrutiny. Thirty-three black professors were interviewed about their participation in a number of presentation contexts, including national conferences, symposia, and campus job talks. Study participants discussed encountering multiple layers of racial stereotyping and bias, and also how their keen racial awareness enabled them to develop strategic coping mechanisms to manage audience reactions. These strategies also represented the self-sacrifices they made that altered their racial identities. By examining black faculty members’ struggles to be valued personally and professionally in white-dominated academic sites, the study findings can enrich critical interpretations of racism in higher education.  相似文献

Abstract

The primary focus of operations management is to add value through operational processes. Considerable attention has been given to using process improvement (PI) techniques to reduce costs and time, in order to develop a competitive advantage for the wider organization. However, this narrow definition of value at times overlooks the triple bottom line (TBL) which can result in a number of unintended consequences, specifically issues related to environmental and social measures of performance. To address this, a stakeholder theory lens will be used to analyze PI activities within the context of small and medium-sized enterprises. The TBL will be used to complement the stakeholder perspective, to interpret the benefits that are realized from PI activities. This article highlights both the direct benefits from PI as well as more indirect benefits realized by involving a selection of salient stakeholders in PI. It will show how a developed view of PI can provide an important mechanism for delivering improvements to a firm’s TBL. The work concludes by highlighting the contributions made to both PI practice and stakeholder theory, while acknowledging the need for more research on PI, both from a stakeholder perspective and how it impacts a firm’s TBL.  相似文献

Angry physicians create problems--for the people they treat and work with, for their administrators, and for their loved ones. Addressing negative emotions is one of the most prevalent organizational and personal challenges facing physician leaders. Solving this problem starts with taking an honest look at the factors and processes that shape physicians' coping patterns. Learning effective emotional management skills is underscored by a simple fact: Emotions are contagious. The Type A behavior pattern (TYABP) refers to an aggressive coping mode. Cross-cultural research suggests that, compared to the general population, physicians show elevated scores on TYABP measures, and that women physicians are at particular risk of developing TYABP. In Part 2 of this series, interpersonal anger management strategies will be presented.  相似文献

One of the most difficult aspects of physician leadership is addressing angry colleagues. The first article in this series called attention to the problems that come with the Type A coping styles of many physicians and outlined strategies for managing oneself. Part 2 provides specific strategies that can be helpful in managing others' anger-generating behaviors and anger reactions. There are eight practical communication guidelines recommended by experts in the field for managing anger in others. They include: Strike while the "iron is warm." Match, then lead. Stay in your own zone. De-escalate the other's angry reactions. Do something different. Be assertive, not aggressive. Use effective negotiation tactics. Operationalize the problem.  相似文献

On the Tukey depth of an atomic measure   总被引:1,自引:0,他引:1  
This paper gives a relation between the convex Tukey trimmed region (see [J.C. Massé, R. Theodorescu, Halfplane trimming for bivariate distributions, J. Multivariate Anal. 48(2) (1994) 188–202]) of an atomic measure and the support of the measure. It is shown that an atomic measure is concentrated on the extreme points of its Tukey trimmed region. A property concerning the extreme points which have 0 mass is given. As a corollary, we give a new method of proof of the Koshevoy characterization result.  相似文献

Modelling for marked point processes is an important problem, but has received remarkably little attention in the statistical literature. The authors developed a marked point process model that incorporates the use of functional data analysis in a joint estimation of the frequency function of the point process and the intensity of the mark, with application to data from 22 lupus patients consisting of times of flares in symptom severity combined with a quantitative assessment of the severity. The data indicate that a rapid decrease in drug dose is significantly associated with a decrease in flare frequency. Experiments with simulated data designed to model the actual data further support this conclusion. The Canadian Journal of Statistics 40: 517–529; 2012 © 2012 Statistical Society of Canada  相似文献

Summary.  We consider the general problem of simultaneously monitoring multiple series of counts, applied in this case to methicillin resistant Staphylococcus aureus (MRSA) reports in 173 UK National Health Service acute trusts. Both within-trust changes from baseline ('local monitors') and overall divergence from the bulk of trusts ('relative monitors') are considered. After standardizing for type of trust and overall trend, a transformation to approximate normality is adopted and empirical Bayes shrinkage methods are used for estimating an appropriate baseline for each trust. Shewhart, exponentially weighted moving average and cumulative sum charts are then set up for both local and relative monitors: the current state of each is summarized by a p -value, which is processed by a signalling procedure that controls the false discovery rate. The performance of these methods is illustrated by using 4.5 years of MRSA data, and the appropriate use of such methods in practice is discussed.  相似文献

An observation ×o is to be classified into one of two normal populations φ1 and φ2. A classification rule, the Two-stage sample Rule, R(TS), whose probability of misclassification, P[MC], is independent of the common but unknown variance is proposed. Some optimal properties of R(TS) are also discussed and some values of P[MC | R(TS)], the probability of misclassification given the rule R(TS), are tabulated.  相似文献

The theoretical price of a financial option is given by the expectation of its discounted expiry time payoff. The computation of this expectation depends on the density of the value of the underlying instrument at expiry time. This density depends on both the parametric model assumed for the behaviour of the underlying, and the values of parameters within the model, such as volatility. However neither the model, nor the parameter values are known. Common practice when pricing options is to assume a specific model, such as geometric Brownian Motion, and to use point estimates of the model parameters, thereby precisely defining a density function.We explicitly acknowledge the uncertainty of model and parameters by constructing the predictive density of the underlying as an average of model predictive densities, weighted by each model's posterior probability. A model's predictive density is constructed by integrating its transition density function by the posterior distribution of its parameters. This is an extension to Bayesian model averaging. Sampling importance-resampling and Monte Carlo algorithms implement the computation. The advantage of this method is that rather than falsely assuming the model and parameter values are known, inherent ignorance is acknowledged and dealt with in a mathematically logical manner, which utilises all information from past and current observations to generate and update option prices. Moreover point estimates for parameters are unnecessary. We use this method to price a European Call option on a share index.  相似文献

This paper presents a very simple approximation, having “graph” accuracy, for calculating bivariate normal probability contours. Such contours are useful in simultaneous inference and other applications. This method is then adapted to approximate roughly bivariate and multivariate normal union probabilities.  相似文献
