Self-Inquisitiveness: the Structure and Role of an Epistemic Virtue

The motivating virtue account claims that inquisitiveness or curiosity is the motivating epistemic virtue. In the case of self-knowledge, self-inquisitiveness, intrinsic and instrumental, is the motivating epistemic virtue that mobilizes other virtues, skills, and epistemic character virtues, needed to achieve such knowledge. Its proper object is substantial self-knowledge, knowledge of one’s dispositions and causal powers that has historically played a central role in philosophy, and is now, under various names, investigated by psychologists. It has been, until recently, comparatively neglected within analytical epistemology of self-knowledge. Self-inquisitiveness thus instantiates the general paradigm of curiosity-inquisitiveness that organizes and motivates other epistemic virtues (virtues-abilities and character virtues). And it is perhaps responsible for intrinsic value of self-knowledge.     

不具有性质(wa)的拓扑空间

设（X，T）是拓扑空间，如果对于任意的开覆盖u和任意的稠密子集D存在X的离散子集F∪→D使得St(F,u)=∪{U∈u:U∩F≠φ}=X，则称（X，T）具有性质（wa)，每一正规空间都具有性质（wa)。M.V.Matveev举例说明了T1空间可以不具有性质(wa)，本文证明了存在很多Hausdorff空间不具有性质（wa)，且进一步举例说明了Tychonoff空间可以不具有性质（wa)，这些结果回答了Matveev的问题。     

The Conjugacy Class Number k(G): A Different Perspective

For a finite group G, let m(G) denote the least positive integer such that the union of any m(G) distinct nontrivial conjugacy classes of G together with the identity of G is a subgroup of G. We prove that m(G) = k(G) ?1 for all m(G) ≥2.     

Against the Minimalistic Reading of Epistemic Contextualism: A Reply to Wolfgang Freitag

Several philosophers have argued that the factivity of knowledge poses a problem for epistemic contextualism (EC), which they have construed as a knowability problem. On a proposed minimalistic reading of EC’s commitments, Wolfgang Freitag argues that factivity yields no knowability problem for EC. I begin by explaining how factivity is thought to generate a contradiction out of paradigmatic contextualist cases on a certain reading of EC’s commitments. This reductio results in some kind of reflexivity problem for the contextualist when it comes to knowing her theory: either a knowability problem or a statability problem. Next, I set forth Freitag’s minimalistic reading of EC and explain how it avoids the reductio, the knowability problem and the statability problem. I argue that despite successfully evading these problems, Freitag’s minimalistic reading saddles EC with several other serious problems and should be rejected. I conclude by offering my own resolution to the problems.     

Virtue -Based Epistemology and the Centrality of Truth (Towards a Strong Virtue-Epistemology)

A strong, strictly virtue-based, and at the same time truth-centered framework for virtue epistemology (VE) is proposed that bases VE upon a clearly motivating epistemic virtue, inquisitiveness or curiosity in a very wide sense, characterizes the purely executive capacities-virtues as a means for the truth-goal set by the former, and, finally, situates the remaining, partly motivating and partly executive virtues in relation to this central stock of virtues. Character-trait epistemic virtues are presented as hybrids, partly moral, partly purely epistemic. In order to make the approach virtue-based, it is argued that the central virtue (inquisitiveness or curiosity) is responsible for the value of truth: truth is valuable to cognizers because they are inquisitive, and most other virtues are a means for satisfying inquisitiveness. On can usefully combine this virtue-based account of the motivation for acquiring knowledge with a Sosa-style analysis of the concept “knowledge”, which brings to the forefront virtues-capacities, in order to obtain a full-blooded, “strong” VE.

A spectral solution of nonlinear mean field dynamo equations: Without inertia

In this paper we describe in detail spectral solution method for solving nonlinear mean field dynamo equations without inertial effects in a rapidly rotating spherical shell filled with electrically conducting fluid taken into account no-slip velocity boundary conditions in the core for a finitely conducting inner core and an insulating mantle. Sample results are provided for nonlinear alpha squared dynamos. The method is suitable for solving many geophysical, astrophysical and engineering problems.

Total Systems Intervention (TSI): A Reconstitution

Total Systems Intervention (TSI) is a very new approach to ‘problem solving’, but has enjoyed a more extensive use than expected at this stage. Early accounts of it have now been explored in some depth in practice and through theoretical discussion. There have been many new insights generated. Conditions are now propitious for a thorough reworking of TSI as a practical tool, to bring it right up-to-date. This article provides a very brief review of uses of TSI, theoretical and practical reflections, plus an extensive overview of the TSI method as it is employed today. TSI's philosophy, principles and process are described and explained. Some ideas for further development are given.     

Constructive (2,3)-generation: A permutational approach

A groupG is said to be (2,3)-generated if it can be generated by two elements of respective orders 2 and 3. The class of these groups has recently received a lot of attention by several authors: a brief survey of the results in this area is given in the introduction. In this paper we show that, ifR is a ring generated by one element of finite multiplicative order, then the analogues of classical groups overR are (2,3)-generated, provided that their rank is sufficiently large. Our lower bound for the rank improves previous results.     

K(A,B,I): II

The KABI conjecture states that double relative K-theory and cyclic homology agree, at least in characteristic zero. We show that K ₂(A, B, I) maps onto HC ₁ (A, B, I) whenever A B is a map of Q-algebras and I BIB. We also reinterpret the KABI conjecture in terms of the injectivity of the inverse limit of the map from NK(A, B, I) to the inverse limit of the truncated polynomial versions of NK(A, B, I).Supported by National Science Foundation Grant RII — 8700009.Partially supported by National Science Foundation Grants DMS — 8503018 and 8803497.     

中国各地区PM_(2.5)影响因素的空间差异特征分析

基于空间变系数模型,采用局部线性BGWR拟合方法,分别从经济、人口和环境的角度,选取9个指标,对2016年中国各地区PM_(2.5)浓度的空间差异性及其影响因素进行探究.结果表明:降水、天气、森林覆盖率、对外开放水平、污染治理和地区生产总值与PM_(2.5)浓度显著负相关;单位GDP能耗、产业结构和城镇化率与PM_(2.5)浓度显著正相关.其中,天气因素和城镇化率的影响程度较其他因素更为显著.最后,提出人口空间合理布局、产业结构优化升级等建议,旨在成功实现PM_(2.5)污染控制和减排.
