在高校跨越式发展进程中落实科学发展观

科学发展观是关于发展规律和策略方法的辩证的哲学思考。在高校跨越式发展进程中贯彻落实科学发展观,需要以辩证的哲学思维处理协调好跨越式发展与波浪式发展的关系;规模扩张与内涵建设的关系;办学资源合理利用与不断积累完善的关系;高校自身发展目标与外部环境条件的关系;继承发展传统优势与培育新增长点的关系;发展特色与全面发展的关系。     

WHAT IS A SCIENTIFIC WORLD VIEW,AND HOW DOES IT BEAR ON THE INTERPLAY OF SCIENCE AND RELIGION?

Abstract. What is a scientific worldview, and why should we care? One worldview can knit together various notions, and therefore understanding a worldview requires analysis of its component parts. Stripped to its minimum, a scientific worldview consists strictly of falsifiable components. Such a worldview, based solely on ideas that can be tested with empirical observation, conforms to the highest levels of objectivity but is severely limited in utility. The limits arise for two reasons: first, many falsifiable ideas cannot be tested adequately until their repercussions already have been felt; second, the reach of science is limited, and ethics, which compose an inevitable part of any useful worldview, are largely unfalsifiable. Thus, a worldview that acts only on scientific components is crippled by a lack of moral relevance. Organized religion traditionally has played a central role in defining moral values, but it lost much of its influence after the discovery that key principles (such as the personal Creator of Genesis) contradict empirical reality. The apparent conundrum is that strictly scientific worldviews are amoral, while many long‐held religious worldviews have proven unscientific. The way out of this conundrum is to recognize that nonscientific ideas, as distinct from unscientific ideas, are acceptable components of a scientific worldview, because they do not contradict science. Nonscientific components of a worldview should draw upon scientific findings to explore traditional religious themes, such as faith and taboo. In contrast, unscientific ideas have been falsified and survive only via ignorance, denial, wishful thinking, blind faith, and institutional inertia. A worldview composed of both scientific components and scientifically informed nonscientific components can be both objective and ethically persuasive.

Deej‐a Vu: Documentary revisits facilitated communication pseudoscience

Deej is a documentary about a young man named Deej who has autism with complex communication needs (i.e., nonverbal autism). To the uninitiated, Deej might look like a poignant story about people misperceiving Deej until he reveals the intelligence hidden inside him. The documentary uses Deej's story to suggest that other people with complex communication needs are similarly misunderstood. In actuality, the documentary is misleading and concerning. Deej demonstrates his hidden intelligence via facilitated communication. The documentary does not mention the science that discredits facilitated communication or the harm that facilitated communication has enabled. In the present paper, I use the history of facilitated communication to examine Deej. I describe how the documentary promotes facilitated communication by encouraging improper forms of scientific reasoning. Finally, I suggest that skepticism toward facilitated communication is necessary to ameliorate its harmful influence and to encourage genuine acceptance of people with complex communication needs.     

一种基于多阶认知诊断模型测评科学素养的方法

科学素养是指作为一名有反思意识的公民所具有的解决科学问题和运用科学理念的能力。为实现在认知诊断中对科学素养的测评, 本文基于PISA 2015科学素养测评框架首次提出科学素养包含的三阶潜在结构, 使用新提出的多阶认知诊断模型对PISA 2015科学测评数据进行分析, 并通过模拟研究探究新模型的心理测量学性能。结果表明：(1)新模型能够较好地分析包含三阶潜在结构的科学素养; (2)科学知识对科学素养的影响最大, 科学背景次之, 科学能力的影响最小; (3)全贝叶斯MCMC算法能够为新模型提供较精准的参数估计。     

IS THEOLOGY RESPECTABLE AS METAPHYSICS?

Theology involves inquiry into God's nature, God's purposes, and whether certain experiences or pronouncements come From God. These inquiries are metaphysical, part of theology's concern with the veridicality of signs and realities that are independent from humans. Several research programs concerned with the relation between theology and science aim to secure theology's intellectual standing as a metaphysical discipline by showing that it satisfies criteria that make modern science reputable, on the grounds that modern science embodies contemporary canons of respectability for metaphysical disciplines. But, no matter the ways in which theology qua metaphysics is shown to resemble modern science, these research programs seem destined for failure. For, given the currently dominant approaches to understanding modern scientific epistemology, theological reasoning is crucially dissimilar to modern scientific reasoning in that it treats the existence of God as a certainty immune to refutation. Barring the development of an epistemology of modern science that is amenable to theology, theology as metaphysics is intellectually disreputable.     

《科学》和《自然》杂志2015年的两篇心理学文章

本文评述了《科学》和《自然》杂志2015年的两篇文章。《科学》上的文章“心理科学的重现性”对100项心理学实验进行了重复验证。结果表明,只有大约多于1/3的原始研究能够重复。该文章对出现这样结果的原因作了分析,并指出这不是心理学的挫折。我们强调科学精神在于它的不确定性,因而科学才能处在不停的探索中。《自然》上的文章“P值仅仅是冰山的一角”,批评了个别心理学杂志禁用P值的做法,指出研究者应该在实验设计、数据处理等实验的前期阶段下功夫,才能防止心理科学的坍塌。我们结合国内研究生培养的现状,就改进心理学研究生的实验训练提出了建议。
