Visual illusions classified

Visual illusions provide evidence of perceptual processes, especially the use of knowledge about objects and the working rules for seeing. The classification of phenomena is necessary for any science because it facilitates induction and deduction. The phenomena of illusions are no exception. It is hoped that the tentative classification presented here may stimulate further research and raise new questions by revealing gaps in the conceptual structure of how perception proceeds. Finally, a speculation is offered for the functional use of sensations, the qualia of consciousness.     

Revelation in Islam

Among the world's religions, Islam has one of the most fully developed understandings of the notion of revelation. It views the whole of the created order as a revelation and, accordingly, considers religious revelation in the form of Scripture as an integral feature of the human condition. It is within this context that Muhammad's own revelatory experiences must be considered. These are well‐attested in the Hadith literature. Islam recognises three distinct grades of revelation. Muhammad's was the highest of these which, as the ahadith make clear, is a “passing into the deep sleep state in full consciousness ...”. The explicit nature of these traditional accounts of prophecy in action, as well as Islam's universalism, sheds light upon revelation in all religious traditions.     

Revelation effect in metamemory

Test items are more likely to be judged as previously studied if they need to be discovered before the recognition decision. In the present experiments, this revelation effect was extended to metamemory judgments. Participants studied word pairs and then tried to recall the second word of each pair when given the first word as a cue. In Experiment 1, a fragment of the target was either gradually increased in size or held constant, and in Experiment 2, sometimes an anagram of the cue was given instead of the cue itself. Thus, for some items, there was a revelation task before a recall attempt. If recall failed, the participants gave feeling-of-knowing (FOK) ratings. In both experiments, the participants gave higher FOK ratings after a revelation task, even though the items that these FOKs referred to remained unrecalled. Analyses showed a criterion shift but no differences in sensitivity.     

Modelling partially cross‐classified multilevel data

This article proposes an approach to modelling partially cross‐classified multilevel data where some of the level‐1 observations are nested in one random factor and some are cross‐classified by two random factors. Comparisons between a proposed approach to two other commonly used approaches which treat the partially cross‐classified data as either fully nested or fully cross‐classified are completed with a simulation study. Results show that the proposed approach demonstrates desirable performance in terms of parameter estimates and statistical inferences. Both the fully nested model and the fully cross‐classified model suffer from biased estimates of some variance components and statistical inferences of some fixed effects. Results also indicate that the proposed model is robust against cluster size imbalance.     

Two Accounts of Qur'anic Revelation

This essay examines the notions of revelation and prophecy as offered by Fazlur Rahman and Nasr Hamid Abu Zayd. Their ideas regarding prophecy and revelation contribute to the clarification of some foundational issues in Islamic theology. For both Rahman and Abu Zayd, theology begins with the idea that divine revelation is intended for human beings. So, even though this revelation is divine in origin, it is also mostly intelligible. This rethinking of the idea of revelation is welcomed by some Muslim thinkers, but has not met with so positive a reception in more traditional Islamic circles. I argue that what makes these human-centric accounts of revelation controversial is the idea of Muhammad's “contribution” to the revelation process and the article investigates this idea as it is formulated in the work of these two scholars.     

Anti-Luck Virtue Epistemology and Divine Revelation

Anti-Luck Virtue Epistemology (ALVE) states that for S to have knowledge, S must have a virtuously formed safe true belief. S’s belief that p is safe if, in most near-by possible worlds where S’s belief is formed in the same manner as in the actual world, S’s belief is true. S’s safe belief that p is virtuously formed if S’s safe belief is formed using reliable and well-integrated cognitive processes and it is to S’s credit that she formed the belief. In this paper, I offer a novel counterexample to ALVE. I offer a case where an individual forms a belief on the basis of divine revelation. Intuitively the person has knowledge, but ALVE predicts otherwise. The upshot is not only that we have a counter example to ALVE, but also, that ALVE may not serve the needs of an adequate religious epistemology.     

Gambling habits of athletes and nonathletes classified as disordered gamblers

The objective of the present study was to determine the forms of gambling that were the most prevalent in those having problems with their gambling. High-risk individuals who were experiencing difficulties with their gambling were examined. Specifically, the gambling behaviors of current athletes, former athletes, and nonathletes were investigated. Only members of these 3 groups with elevated scores on the South Oaks Gambling Screen (SOGS) were tested. Specifically, only those classified as disordered gamblers (SOGS score > or = 3) were recruited. Among these individuals with high SOGS scores, former athletes were more likely to participate in skill-based forms of gambling such as sports gambling and poker card playing, whereas nonathletes were more likely to partake in gambling games that were based predominately on chance factors. Also, former athletes were more likely to wager on the sport they had once played. Findings suggest that a competitive spirit may lead athletes to involvement in skill-based forms of gambling. While other explanations were considered, preliminary indicators support this view.     

The Revelation Argument. A 'Communicational Fallacy'

In this paper it is argued that much can be gained for the analysis and evaluation of arguing when fallacies are not, or not only, conceived of as flawed premise–conclusion complexes but rather as argumentative moves which distort harmfully an interaction aiming at resolving communication problems argumentatively. Starting from Normative Pragmatics and the pragma-dialectical concept of fallacy, a case study is presented to illustrate a fallacy which is termed the 'revelation argument' because it is characterized by an interactor's revealing her thoughts and/or emotions to the addressees and claiming that these would have justificatory or refutatory potential with respect to the problem discussed. Although the revelation argument may not be a paradigm case of resolution- hindering moves, it is an extreme case of flawed reasoning that illustrates plainly the advantages of a communicational perspective on arguing and fallacies.     

RNA酶的发现与启示

酶的本质是蛋白质已经成为生物学领域的共识,然而美国科学家切赫(Thomas R.Cech)和奥尔特曼(Sidney Altman)在研究RNA分子剪切机制的时候观察到某些RNA能够自我进行切割和连接,表现出酶的性质,称为RNA酶。这一重大的发现引起了人们对酶的本质和生命起源问题的进一步探索,也使他们荣获了1989年的诺贝尔化学奖。
