早期民俗学者的田野考察及其方法探索

田野考察作为一种学术研究方法,是近现代以来的人文现象。本文通过追述20世纪早期民俗学者的田野考察活动及其方法论探索,以及他们的困惑、遭遇、成败得失等等。本文试图探讨:一种新兴的学术方法是如何在自觉意识的指导下,经由“田野意识———追求数量———寻求规范”的有趣实践,从而成为一个学科不可或缺的研究方法。

改造中国哲学社会科学界：深度探析研究与评价之研究

步入21世纪,国家层面日渐重视哲学社会科学研究的作用;近10余年,中国社会科学界发表论文批量化涌现.文章意在重申,展开研究之研究的讨论实为反思“为什么”而进行,再度回归研究与评价的本体之讨论.老调重弹,让中国社科研究和评价回归本来之面目.关注评价研究之研究的同时,需要将其转化为规范性的文本或是文件,甚至是制度化的法律文本,用以改造中国社会科学研究之风气.时下,管理当局也在三令五申,社会科学界当事人却难以独善其身;针对于此,笔者提出有待深度探讨和研究的本源性问题.追本朔源,提升研究之研究工作的理论认知水平;推而论之,将研究之研究用以指导社会科学研究界之改造工作,需要局中人共同努力.     

On‐Shelf Availability,Retail Performance,and External Audits: A Field Experiment

A potential answer to retailer's shelf out‐of‐stocks (OOS), where the item is in the store but customers cannot find it, is to employ third‐party service providers to execute audits and corrections. However, given the nontrivial cost of executing external audits, it is still necessary to assess whether external audits are capable of reducing shelf‐OOS, whether they can be performed in an economical way, and whether the benefits from the audits translate into higher sales. In an effort to address these questions, we partnered with a product manufacturer and a retail service provider and conducted a field experiment in a national retailer's store set. We used transactional data to detect abnormal operations and respond to possible shelf‐OOS by sending auditors to correct empty shelves and incorrect inventory records. At the conclusion of the experiment, we found that Stock Keeping Units in the treatment group were less likely to have shelf‐OOS and inventory record inaccuracies, and that our intervention had a positive effect on sales. Furthermore, we found that the external audit initiative is economically viable since these improvements required low auditing efforts after a transitional period, and in steady state the cost of running the program is a small fraction of the benefits it generates. We discuss the limitations of our study and the implications of our findings for researchers and practitioners.

On Maximum Depth and Related Classifiers

Abstract.  Over the last couple of decades, data depth has emerged as a powerful exploratory and inferential tool for multivariate data analysis with wide-spread applications. This paper investigates the possible use of different notions of data depth in non-parametric discriminant analysis. First, we consider the situation where the prior probabilities of the competing populations are all equal and investigate classifiers that assign an observation to the population with respect to which it has the maximum location depth. We propose a different depth-based classification technique for unequal prior problems, which is also useful for equal prior cases, especially when the populations have different scatters and shapes. We use some simulated data sets as well as some benchmark real examples to evaluate the performance of these depth-based classifiers. Large sample behaviour of the misclassification rates of these depth-based non-parametric classifiers have been derived under appropriate regularity conditions.     

阐释的策略——当代文化理念的创新性建构

全球化语境下文化的各个领域都面临着新的阐释,文化理念的创新性建构问题也由此在与传统、现代及后现代文化理念撞击的张力中凸显.尽管当代文化理念在与西方观念的撞击中呈现出回归意识,但不应沿袭传统文化理念的建构模式.文化理念的创新性建构应是立足于当代文化的现实土壤上,在与传统和现代的对话场域中,达到一种融通和批判性超越,生成具有当代视野的文化精神理念.
