A Primer on Rational Consequence Relations,Popper Functions,and Their Ranked Structures

Rational consequence relations and Popper functions provide logics for reasoning under uncertainty, the former purely qualitative, the latter probabilistic. But few researchers seem to be aware of the close connection between these two logics. I’ll show that Popper functions are probabilistic versions of rational consequence relations. I’ll not assume that the reader is familiar with either logic. I present them, and explicate the relationship between them, from the ground up. I’ll also present alternative axiomatizations for each logic, showing them to depend on weaker axioms than usually recognized.     

刑事律师法律地位的三维考察

律师对于刑事辩护业务缺乏热情,刑事诉讼中律师参与刑事辩护的比例有减无增,这种现象与法律和社会对律师角色的片面认识有关。律师执业的个体性、律师辩护的有偿性、律师为犯罪嫌疑人、被告人服务的专一性,使人们对辩护律师的角色认识仅仅停留在把律师作为当事人的辩护人这一点上。然而,无论从应然还是从实然的意义上,我们都应当承认,辩护律师不只是当事人合法权益的保护者,而且也是社会正义的维护者、刑事诉讼过程的监督者     

Perspective Taking and Intergroup Helping Intentions: The Moderating Role of Power Relations1

People are more willing to help those who belong to their own groups than to an out‐group. Research on perspective taking has shown that many forms of in‐group favoritism disappear when people are led to take the perspective of the other group. The current research explores the possibility of increasing the level of intergroup helping by a perspective‐taking manipulation. An experiment in a Polish‐Czech borderland community high school demonstrated that Polish students who were made to imagine that they became members of an out‐group (perspective‐taking manipulation) were more willing to help out‐group members. The moderating role of perceived power is discussed in the context of perspective‐taking theory.     

Retention,Role Modeling,and Academic Readiness: A Perspective on the Ethnic Minority Student in Higher Education

This article discusses retention, role modeling, and academic readiness as these issues relate to ethnic minority students in higher education. The central points of the discussion revolve around the need to stem the unusually high rates of attrition of minority students through academic role modeling and recognition of the concept of delayed academic readiness. Methods of implementing a mentor-student program are also suggested.     

A comparative Perspective on Affirmative Action: Positieve Aktie in The Netherlands

The Netherlands has established a program for minority employment patterned after affirmative action in the United States. Thus, the Sutch experience allows a comparative perspective on American efforts, one made more instructive by the sharp differences in intergroup relations between the two nations. We report on our Dutch research on affirmative action among urban police involving almost 100 intensive individual interviews in yoked sets of three--the minority officer, her or his White co-workers, and their immediate supervisor. Based on this initial, rough comparison, we tentatively advance that contrasting national racial normative structures make critical differences in the reception of the policy. Such problems as solo role and stigma commonly reported in American research appear muted in our Dutch data. Thus, ironically, the American racist legacy that shapes the problems of affirmative action is the same legacy that requires affirmative-action policies in the first place.     

A Terror Management Perspective on the Role of Death-Related Anxiety in Psychological Dysfunction

Building on previous existential theorizing, terror management theory provides a unique approach to conceptualizing the development, maintenance, and impact of psychological disorders. The theory suggests that awareness of mortality creates the potential for anxiety, which is managed by an anxiety-buffering system consisting of one's cultural worldview, self-esteem, and interpersonal attachments. The pursuit of meaning, personal value, and interpersonal connections that motivates much human behavior is driven, in part, by the need to control this potential for death-related anxiety. This article provides an overview of terror management theory and a discussion of its implications for understanding clinical conditions, along with a review of research exploring the roles of death-related anxiety and the anxiety-buffering system in anxiety disorders, posttraumatic stress disorder, and depression.     

Affirmative Action as Help: A Review of Recipient Reactions to Preferential Selection and Affirmative Action

We review research on four areas of recipient reactions to affirmative action: (a) self-evaluations of ability and performance, (b) motivation and task interest, (c) performance and achievement, and (d) evaluations of selection procedures. Not surprisingly, the process by which affirmative action was implemented strongly affected the findings. Self-evaluations of ability and specific components of performance were adversely affected when selection procedures did not provide unambiguous, explicit, and focused evidence of recipient qualifications. In contrast, measures of motivation were largely unaffected by any type of selection, although task choice was adversely affected when the selection process did not provide clear evidence of recipient qualifications. Task performance was complexly affected by selection process and other contextual variables. Finally, selection procedures that did not provide unambiguous, explicit, and focused evidence of qualifications were regarded by recipients as less fair than procedures that did not provide evidence of competencies. We interpret the literature using a model of affirmative action as help (Turner, Pratkanis, & Hardaway, 1991), draw further parallels to research on recipient reactions to aid, and develop strategies for the effective management of affirmative action programs.

Modeling Children's Understanding of Quantitative Relations in Texts: A Developmental Perspective

This article describes developmental models of word problem solving that are grounded in the notion of general developmental constraints of the mind. These models were constructed based on the assumption that differences in children's word problem-solving performance are due, at least in part, to developmental differences in their conceptual structures in the quantitative domain. Three levels of knowledge were identified and modeled. The simplest model represents quantitative relations as an ordered array of mental objects. The next level of the model represents numbers as objects of manipulations open two mental number lines that are coordinated in a tentative fashion. The most complex model represents numerical operations as objects of manipulations on two mental number lines that are well-coordinated with explicit, functional rules. These models were implemented as production systems. The accuracy of the predictions resulting from the simulations of the models was tested in an empirical study. Global tests of the models found a good fit of the data to the models. The results wee consistent with the theoretical analysis that the three levels of knowledge were internally coherent and qualitatively different from each other, and that the models could predict children's performance differences to a satisfactory degree.     

A Closer Look at the Role of Applicant Age in Selection Decisions

Participants evaluated hypothetical applicants recruited from a younger (university students) or older (American Association of Retired Persons) population for 2 young-typed jobs, one more strongly young-typed than the other. Participants were given applicant information, including age and personal characteristics, that varied in the extent to which it was consistent with raters' job stereotypes. Results indicated that younger applicants were evaluated more favorably than older applicants. However, an Applicant Age × Job interaction effect indicated that the older applicant was evaluated less favorably for the more strongly compared with the less strongly young-typed job. In addition. applicants whose personal characteristics (other than age) were more consistent with raters' job stereotypes were evaluated more favorably than applicants whose characteristics were less consistent. Results also indicated that applicant age and personal characteristics interacted to influence applicant evaluations. The implications of these and other study results are discussed.     

The Role of Subjective Task Complexity in Goal Orientation,Self-Efficacy,and Performance Relations

We examined the role of subjective task complexity in goal orientation effects on self-efficacy and performance on a computerized simulation of a class scheduling task (N = 138). Results indicated that goal orientation effects on performance were mediated by subjective task complexity. In addition, our results revealed that subjective task complexity was related to self-efficacy but not cognitive ability. Moreover, subjective task complexity effects on performance were mediated by self-efficacy, and goal orientation effects on self-efficacy were mediated by subjective task complexity. Results are discussed in terms of conceptual relations between goal orientation, subjective task complexity, self-efficacy, and performance.     

交往行为理论视域中的康德审美理论

康德被公认为现代社会基本理念和现代性的主要缔造者。正是如此,康德受到自黑格尔至当代后现代思想家德里达、福柯等人的反思性批判。在当前现代性与后现代性对抗的场景中,对康德的理解如何才能够更具时代的合理性,本文运用哈贝马斯的交往行为理论视域来解读康德审美理论,就重建康德审美理论的当代理解做一探讨。一生活世界视域中的审美判断审美判断是康德审美理论的基本概念。在康德理论体系中,第一批判讨论的是人类认识能力,第二批判讨论的是人类实践能力,而第三批判即《判断力批判》则不仅要协调人类诸认识能力的关系,更重要的是考察认识…     

Applicant Perceptions of Selection Procedures: The Role of Selection Information,Belief in Tests,and Comparative Anxiety

This study addresses the effects of the provision of information on the reliability and validity of selection procedures and the effects of test–taker attitudes (i.e., belief in tests and comparative anxiety) on fairness perceptions. Prior to an actual selection process, applicants (N= 118) were given either information about the reliability and validity of various selection procedures or no information. Next, they evaluated the fairness of eight selection procedures. No significant effect of selection information was found. Belief in tests had significant effects, with applicants high on test belief giving higher fairness ratings than applicants low on test belief. In addition, an interaction effect between test belief and selection procedure was found. For example, test belief had larger effects on fairness for structured interviews, personality inventories, and cognitive ability tests. No significant effect of comparative anxiety on fairness was found.     

A Field Study of the Role of Big Five Personality in Applicant Perceptions of Selection Fairness,Self, and the Hiring Organization

Although there is a growing applicant reactions literature, relatively little work has addressed the role of personality in applicant perceptions. Using a sample of actual law enforcement applicants (N=120), we studied the relationship between Big Five personality measured before a written test and applicants' post‐test fairness perceptions, perceptions of themselves, and perceptions of the hiring organization. Personality was related to applicant perceptions after controlling for gender and test score. Personality also accounted for significant variance in self‐perceptions and perceptions of the hiring organization beyond that accounted for by fairness perceptions. Neuroticism and agreeableness were the most consistent predictors of applicant perceptions. Our discussion focuses on the consideration of individual differences in applicant reactions research.     

A New Perspective on Preferential Treatment: The Role of Ambiguity and Self-Efficacy

Knowledge of being selected preferentially has been shown to have negative effects. This study examined how changing the operationalization of preferential treatment to allow for perceptions of ambiguity in the nature of the selection decision may lead to changes in research conclusions. Eighty-four female undergraduates were led to believe they were selected to perform a mathematical task based on their merit, direct preferential treatment, or a more ambiguous or indirect preferential treatment. Results indicated that participants' self-efficacy levels affected their interpretations of the manipulation and performance. Implications for the study of preferential treatment are discussed.     

Relations Among Preschool Children's Understanding of Visual Perspective Taking,False Belief,and Lying

This study investigated the relations among preschool children's ability to understand that other people see things differently than they do, that other people can believe things differently than the children know to be true, and that they can manipulate others' beliefs through intentional lying. Children between the ages of 3 and 5 were given tasks that tested their knowledge of Level 2 visual perspective taking, understanding of false belief, and the discriminative use of deceptive ploys. The Peabody Picture Vocabulary Test (PPVT-III) was administered as a measure of language proficiency. The children's scores on the three types of tasks were correlated with each other and with children's age, but not with scores on the PPVT-III. Most children either passed all the tasks or failed all the tasks. Regression analyses indicated that scores on visual perspective taking and false belief independently predicted each other, and scores on false belief and the discriminative use of deception independently predicted each other. The results provide evidence that advances in visual perspective taking, false belief understanding, and the discriminative use of deceptive ploys are developmentally related and occur in close synchrony.     

A Gender Role Workshop Focused on Sexism,Gender Role Conflict,and the Gender Role Journey

A 6-day gender role workshop for adult men and women, using the phases of the gender role journey, is presented. The workshop's curriculum and process are described, including its assumptions, norms, and media. Movie clips, music, music videos, and academic content were used to promote participants' learning in both the cognitive and affective domains. Systematic follow-up evaluations of participants ( N =84) in three separate workshops are reported using Likert scaled questions. These evaluations assessed participants' personal learning, emotional reactions, and the workshop's overall impact over l-month and 1-and 2-year follow-up periods. Results indicate that participants were affected personally and professionally over the various time periods.     

The Role of Intentions, Social Norms, and Attitudes in the Performance of Dental Flossing: A Test of the Theory of Reasoned Action

The theory of reasoned action proposed by Fishbein and Ajzen (1975) was tested as an explanatory model for a preventive dental behavior, dental flossing, in a sample of 65 undergraduate students. Intentions and direct attitudes were found to be the strongest predictors of flossing. Social influences exerted their influence by way of direct attitudes. Flossers (>1/week) and non-flossers (<1/week) were observed to agree with belief statements referring to the health value of flossing. However, statements referring to the social and sensory aspects of flossing were found to effectively discriminate the two groups. Implications for health education strategies are discussed in which a greater focus is placed on more immediate social and sensory benefits of flossing rather than on long-term health benefits.
