现代金融学理论的缺陷与解决路径

标准金融学与行为金融学的根本分歧是市场是否具有有效性。作为标准金融学基石的有效市场假说的致命缺陷是检验时点有效,即在任何一个时点上证券价格都即时、准确地反映所有信息,这一理想化的约束条件不仅使该理论的应用价值大打折扣,也使其存在着巨大的理论缺陷。行为金融学正是抓住这一点对其提出了质疑和挑战。在推翻标准金融学的理论假设后的行为金融学也没有建立一个比标准金融学更有实际应用性的学说体系,其应用性甚至远远落后于被其否定的以CAPM、APT、OPT等为代表的标准金融学理论。市场有效周期理论认为,市场有效是一个时期而不是一个时点,通过实证研究可以对该理论进行检验。市场有效周期理论的重要价值主要是在解决标准金融学和行为金融学的分歧上实现了重大突破。     

重塑大学理念——自由教育的复归与超越

自由教育是欧洲教育的传统,至中世纪成为大学的理念.但随着人类文明的不断进步,大学功能的日益发达,作为一种高等教育的哲学理念--自由教育曾受到科学教育、专业教育的非难和挑战,其核心是高等教育领域的"人学"与"科学"之争.即教育的终极关怀是人本身还是人的工具价值问题.本文通过考察自由教育的历史源流、内涵的嬗变,分析其复归的合理性,构建现代大学理念,超越自由教育的传统.     

Statistical Reversion toward the Mean: More Universal than Regression toward the Mean

Schmittlein discussed the lack of universality of regression toward the mean. The present note emphasizes the universality of a similar effect, dubbed “reversion” toward the mean, defined as the shift in conditional expectation of the upper or lower portion of a distribution. Reversion toward the mean is a useful concept for statistical reasoning in applications and is more self-evidently plausible than regression toward the mean.     

Language Reversion among People with Dementia from Culturally and Linguistically Diverse Backgrounds: The Family Experience

Abstract

Culturally and linguistically diverse (CALD) older people with dementia, along with their families, face many unique challenges and have unique needs. One such challenge is language reversion, an issue that has received little research attention. This paper presents the findings of an exploratory study of the experiences of family members of people with language reversion emanating from dementia. Using a qualitative, phenomenological approach, in-depth interviews were conducted with seven participants. The study found that the presence of language reversion created additional challenges for family members of someone with dementia, particularly if the family member did not share the person's first language. Community-based aged care services have the potential to offer valuable support, but barriers of negative past experiences, lack of communication, stigma, cultural understanding, and locality need to be overcome. While further research is recommended, these findings have implications for both policy and social work practice in community-based aged care with CALD populations.

生态环境保护视域下的河套文明复归与展望——河套建立草农结合的生态经济产业的战略构想

目前河套地区的生态环境在严重退化,土地大面积沙化,农业耗水甚多,水质下降。而在古代,河套地区有着很好的生态环境。本原的河套文明应是草原文明——生态文明的一个重要组成部分。目前的河套文明是一个未能实现草农结合,而是逐步被农耕化的过程。解决河套地区的生态环境问题必须复归本原的河套文明,同时应加入现代因素,建立新的农业系统,发展草地农业系统。
