The influence of adults' actions on children's inferences about word meanings

This article first establishes the effect of adults' actions on children's inferences about the shape and material of solid objects, based on data from Japanese 2-, 4-, and 6-year-olds. Japanese 2-year-olds are already sensitive to adults' actions in making inferences, and children become more adept at this as they become older. The invariance of the phenomenon of the effect of actions is then discussed in terms of three of its aspects: across age groups, across languages (the universality of the effect), and across tasks in lexical development. It is suggested that while specific linguistic characteristics (e.g., the means of individuation of entities), and complexity of object shape probably influence the effect of actions, action effects may have a potentially invariant/universal aspect.     

A Uniform Approach for Characterizing the Provably Total Number-Theoretic Functions of KPM and (Some of) its Subsystems

In this article we show how to extract with the use of the Buchholz-Cichon-Weiermann approach to subrecursive hierarchies from Rathjen's 1991 ordinal analysis of KPM a characterization of the provably total number-theoretic functions of KPM and some of its (most prominent) subsystems in a uniform and direct way.     

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。     

Counter-Closure

The focus of this paper is the prima facie plausible view, expressed by the principle of Counter-Closure, that knowledge-yielding competent deductive inference must issue from known premises. I construct a case that arguably falsifies this principle and consider five available lines of response that might help retain Counter-Closure. I argue that three are problematic. Of the two remaining lines of response, the first relies on non-universal intuitions and forces one to view the case I construct as exhibiting a justified, true belief to which none of the usual diagnoses of knowledge failure in Gettier cases apply. The second line involves claiming that Fake Barns and its ilk are misdiagnosed by epistemological orthodoxy as Gettier cases. We are thus confronted by a trilemma: either the case I discuss undermines the first-blush plausible principle of Counter-Closure; or the case I discuss instantiates a novel kind of Gettier case; or a popular conception of a key range of alleged Gettier cases must be rejected. No matter which horn we choose, the case points to a philosophically curious conclusion.     

On Empty Compliments and Deceptive Detours A Neopragmatist Response to Theodore W. Nunez

The philosophical question Nunez raises is whether we can have, as he thinks we need, a theoretical grounding for appeal to the intrinsic value of nature. This article examines the neopragmatist reasons for repudiating metaphysical realism's notions of intrinsicality and subject-independent reality. Following the holism of Donald Davidson and Richard Rorty rather than the epistemological premises of Holmes Rolston and Bernard Lonergan, the author concludes that coping with the ecological crisis does not require conjuring an epistemic crisis. Environmental ethics in neopragmatist hands would seek procedures for bringing about agreement in improving our practices, not our epistemology.     

The Axiology of Moral Experience

This paper clarifies the nature of moral experience, examines its evidential role in supporting moral judgments, and argues that moral experiences can be among the things having intrinsic value. Moral experience is compared with aesthetic experience and contrasted with its close relative, non-moral experience combined with moral beliefs. The concluding sections explore the case for the organicity of intrinsic value and the kind of role such value can play in grounding moral obligation.     

On preferring God's non-existence

For many centuries, philosophers have debated this question: ‘Does God exist?’ Surprisingly, they have paid rather less attention to this distinct – but also very important – question: ‘Would God's existence be a good thing?’ The latter is an axiological question about the difference in value that God's existence would make (or does make) in the actual world. Perhaps the most natural position to take, whether or not one believes in God, is to hold that it would be a very good thing if such a being were to exist. After all, God is traditionally thought to be perfectly powerful and good, and it might seem obvious that such a being's existence would make things better than they would otherwise be. But this judgment has been contested: some philosophers have held that God's existence would make things worse, and that, on this basis, one can reasonably prefer God's non-existence. We first distinguish a wide array of axiological positions concerning the value of God's existence which might be held by theists, atheists, and agnostics alike. We next construe these positions as comparative judgments about the axiological status of various possible worlds. We then criticize an important recent attempt to show that God's existence would make things worse, in various ways, than they would otherwise be.     

Isotonic ordinal probabilistic models (ISOP)

The concept of an ordinal instrumental probabilistic comparison is introduced. It relies on an ordinal scale given a priori and on the concept of stochastic dominance. It is used to define a weakly independently ordered system, or isotonic ordinal probabilistic (ISOP) model, which allows the construction of separate sample-free ordinal scales on a set of subjects and a set of items. The ISOP-model is a common nonparametric theoretical structure for unidimensional models for quantitative, ordinal and dichotomous variables.Fundamental theorems on dichotomous and polytomous weakly independently ordered systems are derived. It is shown that the raw score system has the same formal properties as the latent system, and therefore the latter can be tested at the observed empirical level.I wish to thank 3 reviewers and 2 editors who contributed a lot to the readability and precision of the article.     

A novel working memory task for preschoolers: sensitivity to age differences from 3-5 years

Working memory (WM) plays an important role in children’s learning and is linked to later academic and occupational success. Understanding the early development of WM can provide critical clues regarding the underlying structure of executive functions and how they change over the life span. The main objectives of the present study were to (1) investigate age differences in the development of three components of WM (retrieval, substitution, transformation) on a novel preschool WM measure and (2) explore whether findings are consistent with the hierarchical model of WM development by examining perseverative and non-perseverative WM errors. Perseverative errors were hypothesized to be more strongly associated with problems substituting and transforming a representation held in mind, whereas non-perseverative errors were hypothesized to be associated with problems maintaining a representation in mind. Participants were 64 children ranging in age from 3.0 to 5.6 years. The results provide evidence for the sensitivity of the WM task to age differences from 3 to 5 years and support for the hierarchical model of WM development.
