This article reveals one general scheme for creating counter examples to Bayesian confirmation theory. The reason of the problems is that: in daily life the degree of confirmation is affected not only by probability but also by some non-probabilistic factors, e.g., structural similarity, quantity of evidence, and marginal utility, while Bayesian confirmation theory considers only probabilities to measure the degree of confirmation. This article resolves these problems after some detail analyses, and proposes a new confirmation measure based on these factors.

We introduce a new operator, called rational evaluation, in belief change. The operator evaluates new information according to the agent’s core beliefs, and then exports the plausible part of the new information. It belongs to the decision module in belief change. We characterize rational evaluation by axiomatic postulates and propose two functional constructions for it, based on the well-known constructions of kernel sets and remainder sets, respectively. The main results of the paper are two representation theorems with respect to the (...) two functional constructions. We also compare and connect the evaluation operator with some related operators in belief revision, including contraction, set contraction, and prioritized multiple revision. (shrink)

When an agent can not recognize, immediately, the implausible part of new information received, she will usually first expand her belief state by the new information, and then she may encounter some belief conflicts, and find the implausible information based on her criteria to consolidate her belief state. This process indicates a new kind of non-prioritized multiple revision, called metabolic revision. I give some axiomatic postulates for metabolic revision and propose two functional constructions for it, namely kernel metabolic revision and (...) partial meet metabolic revision, with respect to which the representation theorems are proved. I also compare metabolic revision with some related works in the literature, including semi-revision, merging with integrity constraints, evaluation, and evaluative multiple revision. (shrink)

What is called theory of moral community is a socialpolitical idea that was established by Confucius and Mencius on the base of political practice of Yao, Shun, Yu and King of Chou and that was used as ideology of ancient Chinese Empire. Lao Tzu and Zhuang Tzu criticized the theory of moral community and established their naturalistic philosophical system. Lao Tzu said in the first chapter of Tao Te Ching that “The Tao is too great to be described by the (...) name Tao. If it could be named so simply, it would not be the eternal Tao”. If Tao which is indispensable to mortal fortune can be described, it must have existed in discourse of human beings; If the important pole that accords with fact can be named, it must have named by human beings. So people who lived in ancient times regarded the political idea of Yao, Shun, Yu and King of Chou as Tao that has been justified. At the same time they named Yao, Shun, Yu and King of Chou as sons of Heaven who inherited the vocation of Heaven. Hence by all appearances，Lao Tzu was denying the validity of traditional social-political idea. And Lao Tzu thought the traditional social-political practice, in fact, had kept away from intrinsic morality and switched to extrinsic criterions. Zhuang Tzu, as an inheritor of Lao Tzu, criticized the moral community of Confucius straight from the shoulder. First, according to Zhuang Tzu’s opinion, the system of demise is a way of handing over and taking over power accorded with particular instance of the time which was chosen by Yao, Shun and Yu, but it is not a perfect and universal political pattern as Confucius thought. Second, Zhuang Tzu enumerated many immoral behaviors done by these sons of Heaven, on the one hand, on the other hand he regarded the Confucian politics of all over the world was an hegemonic politics in essence which would destroy human’s moral faith on their autonomy. Contrary to Confucian theory of moral community, Lao Tzu brought forward a social idea of “a little state with a small population" which was often misunderstood as “a small state with a little population”, in fact the idea of “a little state with a small population" is a naturalistic political idea that will safeguard and realize freedom, equality and plural values by weakening compulsion of state and lusts of human beings furthest. Lao Tzu and Zhuang Tzu’s critique and reflection of Confucian theory of moral community, with their social-political idea of “a little state with a small population" will be very helpful to establish correct historical consciousness and build wonderful future society.

In the literature of belief revision, it is widely accepted that: there is only one revision phase in belief revision which is well characterized by the Bayes’ Rule, Jeffrey’s Rule, etc.. However, as I argue in this article, there are at least four successive phases in belief revision, namely first/second order evaluation and first/second order revision. To characterize these phases, I propose mainly four rules of belief revision based on agent’s criteria, and make one composition rule to characterize belief revision (...) as a whole. (shrink)

According to rationalists, synthetic a priori propositions convey new knowledge, whereas analytic propositions are non-informative or vacuous conceptual truths. However, as we argue in this article, each a priori proposition is necessarily true because of its semantic constituents and the way they are combined, and hence can be transformed into its equivalent analytic form. So each synthetic a priori proposition conveys only non-informative conceptual truths like analytic propositions.

IntroductionTranscranial direct current stimulation is a noninvasive brain stimulation technique that applied to modulate brain activity and enhance motor recovery. However, the neurobiological substrates underlying the effects of tDCS on brain function remain poorly understood. This study aimed to investigate the central mechanisms of tDCS on improving the athletic performance of male rowing athletes.MethodsTwelve right-handed male professional rowing athletes received tDCS over the left primary motor cortex while undergoing regular training. The resting-state functional magnetic resonance imaging data were acquired before (...) and after tDCS. Measures of amplitude of low-frequency fluctuation and regional homogeneity were calculated and compared between baseline and follow-up, as well as topological measures including global and local efficiency of functional brain networks constructed by graph theoretical analysis.ResultsMale rowing athletes showed increased isokinetic muscle strength of the left knee and left shoulder after tDCS. Increased ALFF values were found in the right precentral gyrus of male rowing athletes after tDCS when compared with those before tDCS. In addition, male rowing athletes showed increased ReHo values in the left paracentral lobule following tDCS. Moreover, increased nodal global efficiency was identified in the left inferior frontal gyrus of male rowing athletes after tDCS.ConclusionThe findings suggested that simultaneous tDCS-induced excitation over the primary motor cortex might potentially improve the overall athletic performance in male rowing athletes through the right precentral gyrus and left paracentral lobule, as well as left inferior frontal gyrus.
