Extending the theoretical understanding of modern prejudice into the realm of heterosexism, it is argued that shifts in the manifestation of prejudice against lesbians and gay men have occurred resulting in an increasingly multidimensional modern heterosexism. Four subdomains of modern heterosexism are identified that are conceptually and empirical distinct from the more traditional hostile heterosexism: aversive heterosexism, amnestic heterosexism, paternalistic heterosexism, and positive stereotypic heterosexism. The Multidimensional Heterosexism Inventory is offered as an instrument to capture the four theorized subdomains of modern heterosexism, and an examination of reliability and validity of the scale is presented. 相似文献

In this paper the implications of cognitive strain for decision-making effectiveness are explored. Literature concerning the psychological processes of decisionmakers which underlie the operation of cognitive strain and which predispose them to the effects of cognitive strain, is reviewed. Next, the impact of cognitive strain on narrowly constraining or “bounding” rational decision-making is examined, and the choice strategies of satisficing and incrementalizing are criticized as failing to broaden the bounds of rational decision-making. Finally, elements of an eclectic choice strategy designed to assist decision-makers handle the informational demands of complex decision problems are discussed. 相似文献

以TEECE创建的技术创新资源获取机制理论框架为研究起点,进行了开放式创新背景下的拓展。根据其对技术资源与商业化资源的划分,运用"占有机制"与"合约交易"2个关键变量,分别揭示在封闭式创新模式向开放式创新模式转变过程中,创新资源获取机制本质由创新资源控制权拓展为创新资源联合共享,具体表现为2个方面:一是技术资源占有机制由正式制度拓展为正式制度与非正式制度的集合,从而其作用机理从环境决定的外生变量,拓展为企业内生性的战略选择;二是商业化资源交易契约从合约交易拓展为合约交易与嵌入式交易。 相似文献

The authors examine the literature with respect to the pricing of initial public offerings and focus upon the relationship
of pricing to the structure and conduct of the investment banking industry. Using a data base of all share offerings undertaken
in the United States over a two and a half year period, the authors find that there is considerable evidence for the proposition
that large, prestigious, and well capitalised investment banks tend to price their share offerings at a higher absolute level
than those not meeting such characteristics. Using classical statistical methods, the authors find that the pricing strategy
of investment banks is connected to their affiliation with investment funds and unit trusts. The motives for such pricing
strategies, the authors argue, lie with the affiliation of investment banks with investment funds, suggesting that the pricing
of new share offerings may be a means of excluding retail investors from participating in the strong returns such issues exhibit. The authors raise legal and regulatory implications
of their findings in the context of the general consolidation observed within the investment banking industry.

In this article, we first propose the modified Hannan–Rissanen Method for estimating the parameters of autoregressive moving average (ARMA) process with symmetric stable noise and symmetric stable generalized autoregressive conditional heteroskedastic (GARCH) noise. Next, we propose the modified empirical characteristic function method for the estimation of GARCH parameters with symmetric stable noise. Further, we show the efficiency, accuracy and simplicity of our methods with Monte-Carlo simulation. Finally, we apply our proposed methods to model the financial data. 相似文献

The paper discusses a quantile-based definition for the well-known proportional odds model. We present various reliability properties of the model using quantile functions. Different ageing properties are derived. A generalization for the class of distributions with bilinear hazard quantile function is established and the practical application of this model is illustrated with a real-life data set. 相似文献

Objective: Nutrition labels are often underutilized due to the time and effort required to read them. We investigated the impact of label-reading training on effort, as well as accuracy and motivation. Participants: Eighty college students (21 men and 59 women). Methods: The training consisted of a background tutorial on nutrition followed by three blocks of practice reading labels to decide which of two foods was the relatively better choice. Label-reading effort was assessed using an eye tracker and motivation was assessed using a 6-item scale of healthy food-choice empowerment. Results: Students showed increases in label-reading accuracy, decreases in label-reading effort, and increases in empowerment. Conclusions: The nutrition label e-training tool presented here, whether used alone or as part of other wellness and health programs, may be an effective way to boost students’ label-reading skills and healthy food choices, before they settle into grocery shopping habits. 相似文献

The present work is an attempt to estimate the population mean on the current occasion in two-occasion successive (rotation) sampling in presence of random non response situations. The estimation strategy has been constructed under a super-population model design approach with the help of imputation technique. The estimators proposed on the current occasion cover the cases of occurrences random non responses on either of the occasions. Detail behaviors of the proposed class of estimators have been studied and its performance has been examined with the sample mean estimator. The results are demonstrated through empirical studies which establish the effectiveness of the proposed class of estimators. Suitable recommendations have been put forward to the survey statisticians for its practical application. 相似文献

ABSTRACTIn this article, life history methodology and principles of counterstorytelling are used to examine moments when one Black male preservice social studies teacher and three Black male social studies teachers challenge Black masculinist visions of leadership, and moments when they seem complicit in perpetuating these visions. Findings indicate that these educators’ understandings of Blackness, maleness, and the pursuit of Black masculine recognition are fluid, developing and sometimes contradictory. We argue that while necessary across disciplines, interrogations of Black masculinity are uniquely imperative in social studies teacher education due to how assumptions about Blackness and maleness have shaped struggles for Black civic recognition. 相似文献
