Reasoning and Explaining

When regimented in a certain natural way, the concepts of explanation and justification manifest a pattern of interrelations connected more or less systematically to their object. Besides its intrinsic interest, this pattern may give us some insight into the nature, source, and limits of the concept of argument.     

Manifest Rationality Reconsidered: Reply to my Fellow Symposiasts

In this paper, I respond to papers on my Manifest Rationality (2000) by Leo Groarke, Hans Hansen, David Hitchcock, and Christopher Tindale presented at the meetings of the Ontario Philosophical Society, October 2000. From the many useful challenges they have directed at my position, I have chosen to focus on two. The dominant issue raised by their papers concerns my definition of argument, and particularly problems with the idea of a dialectical tier. I have selected that as the first strand. Second, several have raised questions that deal with the relationship between logic, rhetoric and dialectic. That is the second strand.

When Do Replies to the Evolutionary Debunking Argument Against Moral Realism Beg the Question?

Some proponents of the evolutionary debunking argument against moral realism believe that replies that assume substantive moral claims beg the question. In this paper, I give a new account of what's wrong with such replies. On this account, many realists beg the question when they rely on substantive moral claims in their replies to the argument, but naturalists do not. While this account generalizes to some other domains, it allows perceptual and inductive realism to remain undebunked.     

Application of deep transfer learning for automated brain abnormality classification using MR images

Magnetic resonance imaging (MRI) is the most common imaging technique used to detect abnormal brain tumors. Traditionally, MRI images are analyzed manually by radiologists to detect the abnormal conditions in the brain. Manual interpretation of huge volume of images is time consuming and difficult. Hence, computer-based detection helps in accurate and fast diagnosis. In this study, we proposed an approach that uses deep transfer learning to automatically classify normal and abnormal brain MR images. Convolutional neural network (CNN) based ResNet34 model is used as a deep learning model. We have used current deep learning techniques such as data augmentation, optimal learning rate finder and fine-tuning to train the model. The proposed model achieved 5-fold classification accuracy of 100% on 613 MR images. Our developed system is ready to test on huge database and can assist the radiologists in their daily screening of MR images.     

心理表征的可视化途径：基于噪音的反向相关图像分类技术

社会心理学对图像的心理表征研究一直难以将心理活动的内容准确刻画出来。近10年来出现了一种新心理物理学方法——“反向相关图像分类技术”, 该技术假定观察者的反应与视觉噪音存在相关关系, 且反应是依照观察者的社会判断标准进行而非随机做出; 通过对其做出反应的相应噪音模式的足够次数的权重计算与视觉代码显现, 从而将观察者内在的评估特点可视化。该技术已在特质研究、种族和群际偏见等领域取得了一些成果, 但是未来仍需解决实验次数过多, 分离混杂的噪音以及被试的表现等问题, 才能获得更为真实的心理表征。

The small improvement argument

It is commonly assumed that moral deliberation requires that the alternatives available in a choice situation are evaluatively comparable. This comparability assumption is threatened by claims of incomparability, which is often established by means of the small improvement argument (SIA). In this paper I argue that SIA does not establish incomparability in a stricter sense. The reason is that it fails to distinguish incomparability from a kind of evaluative indeterminacy which may arise due to the vagueness of the evaluative comparatives ‘better than,’ ‘worse than,’ and ‘equally as good as.’     

Attitudes Toward Colonialism,Political Dependence,and Independence

Preliminary studies done by Poe on the Psychological Effectiveness Scale (PES), which he introduced, indicate that when it is administered to college students, the instrument has considerable validity and internal consistency reliability. The aim of the present study was to explore further the psychometric attributes of the PES in Ss of a different socioeconomic status. One hundred Ss on a methadone maintenance program were asked to rate themselves and two abstract concepts: “abnormal person” and “typical person.” The findings included coefficient alphas in the .90s, high average item-correlation (total minus item), and a significant difference between the means of the three ratings. These findings confirm that the PES has sufficient reliability and construct validity to justify further use.
