使用似然比D2统计量的题目属性定义方法

题目属性的定义是实施认知诊断评价的关键步骤, 通过有丰富经验的领域专家对题目的属性进行定义是当前的主要方法, 然而该方法受到许多主观经验因素的影响。寻找客观的题目属性定义或验证方法可以为主观定义过程提供策略支持或对结果进行改进, 因此已经引起研究者们的关注。本研究构建了一种简单高效的题目属性定义方法, 研究使用似然比D2统计量从作答数据中估计题目属性的方法, 实现属性掌握模式、题目参数和题目属性向量的联合估计。模拟研究结果表明, 使用似然比D2统计量可以有效地识别题目的属性向量, 该方法一方面可以实现新编制题目属性向量的在线估计, 另一方面可以验证已经定义的题目属性向量的准确性。     

论卫生法的部门法属性

卫生法学者关于卫生法是一个独立部门法的理论存在缺陷,难以得到广泛的认同;从社会法的属性及其起源和发展历程来看,卫生法应属于社会法的范畴;从卫生法自身的特点、立法发展状况以及该领域现存的社会危机来看,卫生法是社会法领域为应对现实的社会危机而实现其内容扩张和功能勃兴的独立部门法。     

Targeting Performance Dimensions in Sequence According to the Instructional Hierarchy: Effects on Children’s Math Work Within a Self-Monitoring Program

Four fifth-grade students were presented with frustration-level math probes while three performance dimensions were measured (i.e., percent intervals on-task, percent correct digits, and digits correct per minute (DCM)). Using a multiple baseline design across participants, students were trained to self-monitor time on-task, accuracy, and productivity in sequence and were given their choice of preferred rewards for increases in each performance dimension. The effects of self-monitoring productivity plus rewards prior to and after reaching on-task and accuracy criteria were also evaluated on a probe basis using an embedded multielement design. Results showed that three of the four students increased DCM when self-monitoring productivity plus rewards, but only after meeting on-task and accuracy criteria. Effects of self monitoring accuracy were mixed, and all students showed high levels of on-task behavior throughout the study. The implications of these results for increasing the effectiveness of self-monitoring through a sequenced approach to academic skill training are discussed.     

The Relationship of Job Attribute Preferences to Employment, Hours of Paid Work, and Family Responsibilities: An Analysis Comparing Women and Men

We used 1997 International Social Survey Programme data from 14 countries to examine the relationship of job attribute preferences to family responsibilities, employment, and paid work hours. Separate regression analyses for women and men examined whether family responsibilities (marriage, children, spousal employment, and housework responsibility) predicted job attribute preferences. Many family responsibilities were significant predictors of men's and women's extrinsic and intrinsic preferences. Family responsibilities also predicted women's flexibility preferences. We next examined whether job attribute preferences were associated with employment and weekly paid work hours when family responsibilities were controlled. Job attribute preferences showed several significant relationships to women's and men's employment and several significant relationships to women's paid work hours.     

EMERGENCE EVERYWHERE?! REFLECTIONS ON PHILIP CLAYTON'S MIND AND EMERGENCE

Abstract. Emergence is a powerful concept marked by great emotional, aesthetic, and intellectual appeal. It makes inroads into the understanding of the most diverse phenomena. Emergence appears to have the potential of explaining anything from the behavior of atoms, ant colonies, and traffic jams to insurance risks, human consciousness, and divine action. Philip Clayton's book Mind and Emergence (2004) offers much‐needed clarification of the philosophical grounding of emergence theory. To a large extent, emergence hinges on the concept of levels and hierarchies in nature. The preferred metaphor is that of a ladder. Given the tendency of concepts like emergence to build ideology, a careful analysis of language and metaphor is called for, however. I argue that the preference for the ladder metaphor does not do justice to the differentiated relationality that is a distinct mark of emergence. This oversight may have detrimental consequences when emergence theory is transferred from natural to social and cultural processes. A hermeneutical analysis suggests that better metaphors and visualizations need to be found. As an invitation to consider alternatives, some examples of complex regular poly topes are offered.     

Support for exclusionism as an independent dimension of social dominance orientation in mainland China

Three studies using exploratory and confirmatory factor analyses provided consistent evidence for a three-factor model of the social dominance orientation (SDO) in Mainland China. Support for exclusionism, which was not found in previous research, emerged as an independent SDO factor (Studies 1, 2, and 3). In Study 2, this factor predicted SDO difference between a high status group (managers) and a low status group (entry-level employees). In Study 3, this factor correlated positively with authoritarianism and negatively with altruism. These results provided evidence for the validity of this new SDO factor. The findings are discussed in terms of their relations to China's cultural tradition and contemporary economic development.     

层次,形式与实在

Scientific progress in the 20th century has shown that the structure of the world is hierarchical. A philosophical analysis of the hierarchy will bear obvious significance for metaphysics and philosophy in general. Jonathan Schaffer’s paper, “Is There a Fundamental Level?”, provides a systematic review of the works in the field, the difficulties for various versions of fundamentalism, and the prospect for the third option, i.e., to treat each level as ontologically equal. The purpose of this paper is to provide an argument for the third option. The author will apply Aristotle’s theory of matter and form to the discussion of the hierarchy and develop a theory of form realism, which will grant every level with “full citizenship in the republic of being.” It constitutes an argument against ontological and epistemological reductionism. A non-reductive theory of causation is also developed against the fundamental theory of causation.     

The development of category learning strategies: What makes the difference?

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children’s difficulty in acquiring categories at the subordinate level grounded on these distinct comparison processes. Adults and children performed category learning tasks in which they were exposed either to pairs of objects from the same novel category or pairs of objects from different categories. The objects were designed so that for each category learning task, two features determined category membership whereas two other features were task irrelevant. In the learning stage participants compared pairs of objects noted to be either from the same category or from different categories. Object pairs were chosen so that the objective amount of information provided to the participants was identical in the two learning conditions. We found that when presented only with object pairs noted to be from the same category, young children (6 ? YO ? 9.5) learned the novel categories just as well as older children (10 ? YO ? 14) and adults. However, when presented only with object pairs known to be from different categories, unlike older children and adults, young children failed to learn the novel categories. We discuss cognitive and computational factors that may give rise to this comparison bias, as well as its expected outcomes.     

论"行为事实属性"是一个错误概念——兼论王海明的伦理规范推导公式的失误

“行为事实属性”是王海明的伦理规范推导公式的核心概念,是其整个伦理体系的基础。他创造此概念的目的是想表达这样一个重要思想：人们制定行为规范时必须以该行为的客观效果为基础,而不能仅从主观愿望出发。这一思想具有重要理论意义。但该概念不仅不能表达出这一思想,而且还犯了诸多构词法和逻辑学错误,引起严重的思想混乱。王海明创造这一错误概念的理论原因是他对伦理规范制定程序的理解过于简单且存在混乱,为此,本文提出一个替代公式。     

Categorical Abstract Algebraic Logic: Prealgebraicity and Protoalgebraicity

Two classes of π are studied whose properties are similar to those of the protoalgebraic deductive systems of Blok and Pigozzi. The first is the class of N-protoalgebraic π-institutions and the second is the wider class of N-prealgebraic π-institutions. Several characterizations are provided. For instance, N-prealgebraic π-institutions are exactly those π-institutions that satisfy monotonicity of the N-Leibniz operator on theory systems and N-protoalgebraic π-institutions those that satisfy monotonicity of the N-Leibniz operator on theory families. Analogs of the correspondence property of Blok and Pigozzi for π-institutions are also introduced and their connections with preand protoalgebraicity are explored. Finally, relations of these two classes with the (, N)-algebraic systems, introduced previously by the author as an analog of the -algebras of Font and Jansana, and with an analog of the Suszko operator of Czelakowski for π-institutions are also investigated.
