Milestones in the development of infant numeracy

This article deals with the development of numeracy among young children of the four to seven year age group. The research investigation described had two aims: to see how early numeracy develops in children of different ages; and to see whether there are fixed points which might serve as milestones in the development of infant numeracy. The results of this investigation involving 96 children indicate a strong development of numeracy skills during this period. With reference to the literature, it is also shown that certain items of a test previously developed for this purpose may be taken as core items that do indeed represent milestones in the development of infant numeracy.     

An Operational Logic of Proofs with Positive and Negative Information

The logic of proofs was introduced by Artemov in order to analize the formalization of the concept of proof rather than the concept of provability. In this context, some operations on proofs play a very important role. In this paper, we investigate some very natural operations, paying attention not only to positive information, but also to negative information (i.e. information saying that something cannot be a proof). We give a formalization for a fragment of such a logic of proofs, and we prove that our fragment is complete and decidable.     

The relevance of attachment theory to a contemporary Jungian view of the internal world: internal working models, implicit memory and internal objects

In this paper I examine the various meanings of the term 'internal object' and the differences between various theoretical models for the formation of internal objects. I suggest that the idea in attachment theory of 'internal working models' emphasizes the internal world as one consisting of unconscious internalized patterns of emotional relationships. The term 'internal object' lacks this clarity and the different meanings it carries within differing theoretical frameworks are a source of confusion. I describe the role implicit memory plays in the formation of 'internal working model's and suggest that these offer us an alternative explanation for unconscious fantasy and for object relationships to that of instinctual drives. This model is then brought to bear on contemporary Jungian concepts of the internal world, with a suggestion that, seen in this light, Jung's formulation of the concept of the complex has many features in common with the 'internal working model' of attachment theory.     

Latent variables should remain as such: Evidence from a Monte Carlo study

Use of subject scores as manifest variables to assess the relationship between latent variables produces attenuated estimates. This has been demonstrated for raw scores from classical test theory (CTT) and factor scores derived from factor analysis. Conclusions on scores have not been sufficiently extended to item response theory (IRT) theta estimates, which are still recommended for estimation of relationships between latent variables. This is because IRT estimates appear to have preferable properties compared to CTT, while structural equation modeling (SEM) is often advised as an alternative to scores for estimation of the relationship between latent variables. The present research evaluates the consequences of using subject scores as manifest variables in regression models to test the relationship between latent variables. Raw scores and three methods for obtaining theta estimates were used and compared to latent variable SEM modeling. A Monte Carlo study was designed by manipulating sample size, number of items, type of test, and magnitude of the correlation between latent variables. Results show that, despite the advantage of IRT models in other areas, estimates of the relationship between latent variables are always more accurate when SEM models are used. Recommendations are offered for applied researchers.     

西方公共行政及其正义价值

公共行政本质上所具有的伦理特性以及公共行政理论和范式在不同发展时期所具有的不同特点和价值诉求,使得从伦理的角度对公共行政进行审视成为可能。公共行政正义价值既体现了民主社会自由、平等的价值追求,也蕴涵着公共行政本身所具有的对公共利益的价值取向,同时也是公共行政人员德性的体现。     

Substance or System as Foundational Metaphor for a Contemporary Christian World View?

Natural scientists increasingly employ the notion of system, i.e. organized groups of individual entities in dynamic interrelation, as a controlling metaphor in their analysis of physical reality, thereby reflecting a new emphasis on ecology and a holistic approach to reality. A.N. Whitehead’s understanding of the reciprocal cause-and-effect relation between constituent actual entities and the governing structure of the “society” to which they belong provides philosophical grounding for this new methodology and removes the danger of regarding systems as completely deterministic rather than open-ended and self-organizing. Likewise, a systems-oriented approach to the Christian doctrines of the Trinity, the Incarnation and Eschatology clears up residual ambiguities in the traditional understanding of those same beliefs.     

解题策略的同质性和线性逻辑斯谛模型的拟合

为探讨线性逻辑斯谛模型（ＬＬＴＭ）的拟合条件及其和解题策略同质性之间的关系,让被试比较两个负整数指数幂的大小,发现全体被试的数据不能与拉希模型及ＬＬＴＭ相拟合。把被试按其解题策略分成不同策略组后,同一策略组被试的数据可以拟合于拉希模型,但对于ＬＬＴＭ,同一策略组的数据中部分项目的拟合较好,另外一些项目的拟合较差。这一结果表明,解题策略的同质性是ＬＬＴＭ拟合的必要条件,但还不是充分条件。     

医学伦理教育中隐性课程的负面影响及其消解对策

在正规医学伦理学课程以外,还存在对医学生道德发展产生重要影响的隐性课程。如教育引导不当,隐性课程会给医学生伦理素养、价值观念和行为方式等带来负面影响,造成医学伦理教育与临床实际行为之间的脱节。改进医学伦理教育,需要明确和重视隐性课程的存在。消除其负面影响,需要加强正规医学教育中伦理文化和价值观的传播,充分发挥专业教学过程中隐性课程的积极作用,系统设计、辩证运用隐性课程对医生角色塑造的影响。
