Total systems intervention and human inquiry: The search for a common ground

Total Systems Intervention (TSI) is an approach to intervening in problem situations which has much to offer where complex interacting issues need to be addressed by the complementary use of intervention methodologies. That such an approach has much in common with Action Research (AR) has been recognized, with much recent effort being devoted to the relationship between AR and Critical Systems Thinking (CST), the theoretical endeavor underpinning TSI. This paper further develops this line of debate and relates AR or Human Inquiry (HI) more directly to TSI, using an information systems intervention to enhance the study. The outcome is a demonstration of how TSI implicitly uses techniques informed from the field of Action Research, and how a more thorough synthesis of HI with TSI might serve to improve the overall intervention process.     

哪种文化?哪种多元化?——试论"文化多元化"与我国文学发展的关系

在全球化语境和后现代氛围中,中国文学创作、文学批评、文学理论的发展面临巨大的挑战;我们应该反思历史,审时度势、认清目标、坚定信念,为建设“文化多元化”中有影响力的“一元”——中国文化、文学的整体性特色而努力;但作为一种文化策略的“文化多元化”,其涵义暧昧、含混,充满歧义,一定程度上正影响着新世纪中国文学的健康发展。     

The genetic diversity of cen-tral and peripheral popula-tions of ratlike hamster(Cricetulus triton)

The impact of habitat fragmentation and isolation on the genetic diversity of populations has attracted much attention in studies of meta-population and conservation biology. In this work, using the randomly amplified polymorphic DNA (RAPD) technique, we studied the genetic diversity of central, peripheral and peninsular populations of ratlike hamster, which were collected in five locations of the North China Plain and its surrounding areas, in 1999. The study revealed that, ⅰ) the genetic diversity of central population of Raoyang County＞the sub-central populations of Gu'an County and Taikang County＞the peripheral population of Shunyi District＞the peninsular population of Mentougou District; ⅱ) the genetic diversities of the five populations were positively correlated to the nearest distances to the peripheral line of population distribution; ⅲ) there were significant differences of gene frequencies of some RAPD fragments among the five populations. More RAPD fragments disappeared in peripheral populations than in central or sub-central populations. The frequencies of two RAPD fragments were correlated to the latitude. This study clearly indicated that the variation of the genetic diversities of the five populations was caused by edge effect and frag- mentation through the enhanced inbreeding and genetic drift, and thus supported the view that habitat fragmentation and related edge effect reduce the population genetic diversity.

Monitoring the sandstorm during spring season 2002 and desertification in northern China using SSM/I data and Getis statistics

A massive sandstorm enveloped most part of northern China during the spring season 2002. Monitoring the evolution of sandstorm and desertification has become one of the most serious problems for China's environment. Since 1989, one of the most advanced and operational passive microwave sensors is the DMSP SSM/I (special sensor microwave imager) operated at seven channels (19, 37, 85 GHz with the vertical and horizontal polarization and 22 GHz with vertical polarization only). In this paper, the sandstorm and desertification indexes, SDI and DI, are derived from the radiative transfer equation, and are employed with multi-channel measurements of the DMSP SSM/I for monitoring the sandstorm and desertification in northern China. Some SSM/I data in 1997 and 2001 are employed. The algorithm of Getis statistics is developed to categorize the spatial correlation and its evolution these days. It is demonstrated that the SSM/I indexes, SDI and DI, and its Getis statistics are well applicable for monitoring the sandstorm and desertification.

南京椴群体遗传多样性和遗传结构分析

【目的】 南京椴(Tilia miqueliana)为江苏省重要的乡土树种,野外资源稀缺。南京椴野外群体遗传多样性和遗传结构的探索,可为资源保护、品种选育及遗传改良提供依据。【方法】 以南京椴5个天然群体[江苏宝华山(P1)、牛首山(P2)、安徽皇藏峪(P3)、安徽蜀山(P4)和浙江天台山(P5)]93个体为实验材料,选用15对多态性EST-SSR引物,进行遗传多样性及群体遗传结构分析。【结果】 ①用15对引物共检测等位基因数(A)总和为96,平均值为6.4,四倍体基因型(G)和四倍体特异基因型(G_i)总和分别为441和251,特异基因型比率(R₁)和种质鉴别率(R₂)均值分别为45.73%和17.99%。②在5个群体中,每个位点等位基因数(A_loc)和四倍体基因型丰富度均值(G_loc)分别为5.50±2.43和9.41±4.29;平均观测杂合度(H_o)和平均期望杂合度(H_e)为0.61±1.43和0.62±0.14。参考各群体G_loc和H_e值,确定遗传多样性较高的群体为P1和P3。③群体间遗传分化较小,遗传分化系数(G_st)仅为0.030;AMOVA分子变异分析显示,群体多样性水平变异来自于群体内(96%)。④聚类和遗传结构Structure分析显示,5个群体可划分为2组(组1包括P1、P2和P5;组2包括P3和P4)。Mental检验结果表明遗传距离与地理距离之间无显著相关。【结论】 南京椴群体均具有丰富的遗传多样性,其中宝华山群体和皇藏峪群体多样性较高,群体扩张可能是以这两个种群为中心,经人类活动迁移至其他区域。但南京椴群体间未形成明显分化,主要是由于植株寿命长,群体缺乏自然更新,加之群体间存在人为种子传播。因此,本研究提出通过建立隔离区,明确优先保护群体、加大植株异交,并采用人工繁育及种质回迁的方式保护南京椴野外群体。
