三值关联规则在不确定性知识表示及推理性的应用

动态分类是指对象所属的类可随时间而变化。在进行系统分析和软件开发中,需要真实地描述研究对象在其生命周期中的变化,动态分类正是这样一种机制。但是由于许多面向对象程序设计语言都不支持动态分类,因此需要用别的方法来描述动态分类,文中给出了用ＵＭＬ表达动态分类的四种机制,并对这四种机制进行了比较。     

Effect of display location on control-display stereotype strength for translational and rotational controls with linear displays

Experiments were designed to investigate the effects of control type and display location, relative to the operator, on the strength of control/display stereotypes. The Worringham and Beringer Visual Field principle and an extension of this principle for rotary controls (Hoffmann E.R., and Chan A.H.S. 2013). “The Worringham and Beringer ‘Visual Field’ Principle for Rotary Controls. Ergonomics.” 56 (10): 1620–1624) indicated that, for a number of different control types (rotary and lever) on different planes, there should be no significant effect of the display location relative to the seated operator. Past data were surveyed and stereotype strengths listed. Experiments filled gaps where data are not available. Six different control types and seven display locations were used, as in the Frame of Reference Transformation Tool (FORT) model of Wickens et al. (Wickens, C.D., Keller, J.W., and Small, R.L. (2010). “Left. No, Right! Development of the Frame of Reference Transformation Tool (FORT).” Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting September 2010, 54: 1022–1026). Control/display arrangements with high stereotype strengths were evaluated yielding data for designers of complex control/display arrangements where the control and display are in different planes and for where the operator is moving. It was found possible to predict display/control arrangements with high stereotype strength, based on past data.

Practitioner Summary: Controls and displays in complex arrangements need to have high compatibility. These experiments provide arrangements for six different controls (rotary and translational) and seven different display locations relative to the operator.     

Coping With Stereotype Threat: Denial as an Impression Management Strategy.

Four experiments tested the hypothesis that people who are concerned with impression management cope with stereotype threat through denial. Consistent with this hypothesis, temporary employees threatened by a stereotype of incompetence (Study 1) and hostel-dwelling older adults (Study 2) were more likely to deny incompetence if they were high in impression management. African Americans (Study 3) showed a similar pattern of denying cognitive incompetence, which emerged primarily when they were interviewed by a White experimenter and had attended a predominantly Black high school. In Study 4, White students who expected to take an IQ test and were threatened by a stereotype of being less intelligent than Asians were more likely to deny that intelligence is important if they were high in impression management.

Stereotype Threat and Group Differences in Test Performance: A Question of Measurement Invariance.

Studies into the effects of stereotype threat (ST) on test performance have shed new light on race and sex differences in achievement and intelligence test scores. In this article, the authors relate ST theory to the psychometric concept of measurement invariance and show that ST effects may be viewed as a source of measurement bias. As such, ST effects are detectable by means of multigroup confirmatory factor analysis. This enables research into the generalizability of ST effects to real-life or high-stakes testing. The modeling approach is described in detail and applied to 3 experiments in which the amount of ST for minorities and women was manipulated. Results indicate that ST results in measurement bias of intelligence and mathematics tests. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reactions to Counterstereotypic Behavior: The Role of Backlash in Cultural Stereotype Maintenance.

Social and economic sanctions for counterstereotypical behavior have been termed the backlash effect (L. A. Rudman, 1998). The authors present a model of the role of backlash in cultural stereotype maintenance from the standpoint of both perceivers and actors. In Experiments 1 and 2, participants lost a competition to either atypical or typical men or women and subsequently showed greater tendency to sabotage deviants. Moreover, undermining deviants was associated with increased self-esteem, suggesting that backlash rewards perceivers psychologically. Experiment 3 showed that gender deviants who feared backlash resorted to strategies designed to avoid it (e.g., hiding, deception, and gender conformity). Further, perceivers who sabotaged deviants (Experiment 2) or deviants who hid their atypicality (Experiment 3) estimated greater stereotyping on the part of future perceivers, in support of the model's presumed role for backlash in stereotype maintenance. The implications of the findings for cultural stereotypes are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Complementary Justice: Effects of "Poor but Happy" and "Poor but Honest" Stereotype Exemplars on System Justification and Implicit Activation of the Justice Motive.

It was hypothesized that exposure to complementary representations of the poor as happier and more honest than the rich would lead to increased support for the status quo. In Study 1, exposure to "poor but happy" and "rich but miserable" stereotype exemplars led people to score higher on a general measure of system justification, compared with people who were exposed to noncomplementary exemplars. Study 2 replicated this effect with "poor but honest" and "rich but dishonest" complementary stereotypes. In Studies 3 and 4, exposure to noncomplementary stereotype exemplars implicitly activated justice concerns, as indicated by faster reaction times to justice-related than neutral words in a lexical decision task. Evidence also suggested that the Protestant work ethic may moderate the effects of stereotype exposure on explicit system justification (but not implicit activation).

Attentional processes in stereotype formation: A common model for category accentuation and illusory correlation.

Stereotype formation may be based on the exaggeration of real group differences (category accentuation) or the misperception of group differences that do not exist (illusory correlation). This research sought to account for both phenomena with J. K. Kruschke's (1996, 2001, 2003) attention theory of category learning. According to the model, the features of majority groups are learned earlier than the features of minority groups. In turn, the features that become associated with a minority are those that most distinguish it from the majority. This second process is driven by an attention-shifting mechanism that directs attention toward group-attribute pairings that facilitate differentiation of the two groups and may lead to the formation of stronger minority stereotypes. Five experiments supported this model as a common account for category accentuation and distinctiveness-based illusory correlation. Implications for the natures of stereotype formation, illusory correlation, and impression formation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stereotype distinctiveness: How counterstereotypic behavior shapes the self-concept.

Three experiments examined the relationship between distinctiveness and self-schematicity. Experiment 1 revealed that people were more likely to be self-schematic in domains of strong performance when they felt distinct from family and peers in those domains. Experiments 2 and 3 extended this finding into the arena of stereotypes by demonstrating that people were more likely to be self-schematic in domains of strong performance when their performance was counterstereotypic rather than stereotypic. In particular, African Americans and women were more likely to be schematic for intelligence than Caucasians and men if they performed well academically, whereas Caucasians—especially men—were more likely than African Americans to be schematic for athletics if they performed well athletically. These results suggest that counterstereotypic behavior plays a uniquely powerful role in the development of the self-concept. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
