解析《野性的呼唤》中的自然主义

杰克.伦敦是美国自然主义作家中的杰出代表,他的作品《野性的呼唤》则充分体现了战胜敌人后而存活所需的力量与勇气,表达了适者生存的原则。而巴克传奇经历及其主题思想的揭示对当今中国不能不说有其特定的社会教育意义。     

Diagnostics for quasi-likelihood nonlinear models

Quasi-likelihood nonlinear models (QLNMs) are an extension of generalized linear model and include a widen class of models as special cases. This article investigates some diagnostic methods in QLNMs. An equivalency between a case-deletion model and a mean-shift outlier model in QLNM is established. Two simulation study and a real dataset are used to illustrate the proposed diagnostic methods.     

金融危机以来美国贸易逆差的调整目标区间考察

2008年金融危机以来,美国长期巨额贸易逆差调整广受关注,此问题涉及到调整目标和调整成效的讨论.美国贸易逆差调整的目标主要包括四个方面:一是把控国际贸易秩序的话语权;二是推进再工业化,抢占新一轮产业革命的制高点;三是保持经济相对稳定增长、相对充分的就业与低通胀;四是继续维持美元霸权地位.金融危机后的再工业化战略实施及美国贸易政策的调整使得美国商品贸易逆差幅度缩小,目标逐步趋近,预计以美国贸易逆差占GDP的比重来衡量的调整目标将在一定区间内继续波动,但较21世纪以来的近二十年收窄.而COVID-19疫情的冲击将使美国贸易逆差的调整目标开始偏向经济复苏与经济增长.     

The elites’ collective subjectivities of the history of ethnic politics in Malaysia

ABSTRACT

Malaysia is one of the multi-ethnic, multi-cultural and multi-religious countries in Southeast Asia. Due to the pluralistic nature of Malaysia, it has a political structure based on ethnic politics. The ethnic preferential policies affected most domains of this country. The objective of this article is to examine the origin and background of ethnic politics in Malaysia. Findings of this study indicate that, ethnic politics originated during the British colonial period, it became a tool used by the Barisan Nasional for the legitimacy of regime. Moreover, ethnic politics in Malaysia today is intertwined with religion. Besides, there is the dilemma of the choice between the interest of certain ethnic group and national interests. However, with the opposition coalition Pakatan Harapan won the election in 9th May, UMNO-led BN lost power and interrupted its 61 years control, which leaves us an interesting topic to think about the future of Malaysian ethnic politics.     

Acceptance of automation manufacturing technology in China: an examination of perceived norm and organizational efficacy

Abstract

With a shift to more automation technology, social acceptance of technology plays an important role in the manufacturing sector. To what extent this occurs, and affects the adoption of technology, has been less researched, but is important in deciding how such technology is introduced, and the nature of the shift from labour-intensive manufacturing to automation. This research applies the revised technology acceptance model (TAM) to examine the impact of social and individual antecedents on the acceptance of automation manufacturing technology. Survey data are collected from 258 Chinese manufacturers. Results suggest that perceived norms significantly affect organizational intention to use automation manufacturing technology both directly and via perceived usefulness; organizational efficacy explains the intention to use via mediating effect of perceived usefulness and perceived ease of use. This research is one of the first extending and applying TAM from individuals to organizations.     

COWORDS: a probabilistic model for multiple word clouds

Word clouds constitute one of the most popular statistical tools for the visual analysis of text documents because they provide users with a quick and intuitive understanding of the content. Despite their popularity for visualizing single documents, word clouds are not appropriate to compare different text documents. Independently generating word clouds for each document leads to configurations where the same word is typically located in widely different positions. This makes it very difficult to compare two or more word clouds. This paper introduces COWORDS, a new stochastic algorithm to create multiple word clouds, including one for each document. The shared words in multiple documents are placed in the same position in all clouds. Similar documents produce similar and compact clouds, making it easier to simultaneously compare and interpret several word clouds. The algorithm is based on a probability distribution in which the most probable configurations are those with a desirable visual aspect, such as a low value for the total distance between the words in all clouds. The algorithm output is a set of word clouds that are randomly selected from this probability distribution. The selection procedure uses a Markov chain Monte Carlo simulation method. We present several examples that illustrate the performance and visual results that can be obtained by our algorithm.

“北人”“南物”与唐后期南北问题的重新审视——以南贬北人间的礼物馈赠为中心

唐后期,南贬北人之间存在一种互赠南方物产的风气。在一些独特的南方物产交换行为的背后实际上蕴含着某种南北互动信息。蕲州簟与文石枕的赠送既能够使双方的情感得以交织与升华,更重要的是使南贬北人在自己编织的礼物交换网络中逐渐找到了环境应对的手段与方法,在积极的个人调适中,使北人与南方环境逐渐融合。而斑竹杖与壁州鞭的赠送则具有南贬北人调适贬谪心态之功用,表达了他们对南方生存现状的强烈不满,以及逃离现实的深切渴望。在环境应对与心态调适的同时,郴笔、叠石砚与叠石琴荐的赠送又体现出南贬北人所持有的正统身份认同观念,在一定程度上阻碍着南北的整合趋势。南贬北人对南方主动的排斥与被动的适应,共同构成了唐后期南贬北人在南方的生存状态。这一充满矛盾的生存状态,使得南北的差异与统一、冲突与整合不时发生着博弈性的变奏,这些历史细节在一定程度上影响着唐后期南北历史的发展进程。     

近三十年钱锺书诗学方法论研究述评

自1979年至今，中外学界关于钱锺书诗学方法论的研究走过了30多年。这段研究史大致可以“四个阶段”和“两大主潮”加以概括:“四个阶段”即研究的初始期(1979—1986)、发展期(1987—1999)、论争期(2000—2007)和沉潜期(2008至今)；“两大主潮”指的则是“打通说”和“阐释循环说”两大宏观研究的趋势。对这一研究史的考察有助于整理、吸收前人的研究成果，也可藉此发现当前“钱学”方法论研究的三大困境，即比重失调、概念危机和问题意识的欠缺。寻求一个新的研究视角成为实现钱锺书诗学方法论研究新进展的当务之急。
