“树”与“楼”——台湾女性诗作中“女性经验”的一个成长维度

“女性经验”是台湾女性诗人诗歌成长的一个空间,譬如“树”和“楼”意象就是这个空间中一个典型的经验维度。在这个空间里,女性找到了提升自我的凭借,也回应了社会对她们的压制,她们在不同的“经验”之路上,把记忆与希望都放大到了和男性强势话语相提并论的起点上,给自己也给了世界一个探究当代台湾文化一个重要窗口。

Understanding the experience of stressors: The use of sequential analysis for exploring the patterns between various work stressors and strain

The availability of traditional self-report instruments for measuring work stressors may have diverted attention from exploring the way in which different stressors relate to one another. In order to develop a better understanding of the nature of the stressor experience a study was undertaken to explore the stressor-strain relationship using sequential tree analysis, a stepwise procedure that provides a “visual display” of the patterns and associations between stressors and strains. The study employed a sample of 695 principals and deputy principal teachers of secondary schools in New Zealand, who received a questionnaire measuring stressors and strains. SPSS AnswerTree® (version 2.0.1) was used to identify the patterns of association. The patterns of stressors that emerge from this analysis were used in a didactic or illustrative way to identify issues of measurement that may need to be resolved in order to derive a better understanding of the stressor experience. Different stressor patterns were associated with different levels of, but lower levels of strain were not simply the obverse of those stressors that cause higher levels of strain. Two not mutually exclusive issues emerge from the results, suggesting that stressor measurement practices may need to be reviewed. The first includes structural level issues such as considering the number, type, and potency of different stressors. The second includes issues best described as conditions of association. These concern understanding why different stressor patterns form, the relationship between stressors in those patterns, and the potency of patterns.     

临界二元村临界输入的一种启发式排序方法

临界二元树ＣＢＴ（ｃｒｉｔｉｃａｌＢｉｎａｒｙＴｒｅｅ）作为描述电路功能的一种方法，可以用于呆滞型故障模型的电路功能级测试生成。其基于知识的树结构特别适用于专家系统环境［１］。然而ＣＢＴ的大小取决于临界输入的识别，好的临界输入排序可以大大缩小ＣＢＴ规模。文中提出了一种临界输入的启发式识别方法，以求获得较小的ＣＢＴ，加速测试生成过程。     

Estimation of General Stationary Processes by Variable Length Markov Chains

We develop new results about a sieve methodology for the estimation of minimal state spaces and probability laws in the class of stationary processes defined on finite categorical spaces. Using a sieve approximation with variable length Markov chains of increasing order, we show that an adapted version of the Context algorithm yields asymptotically correct estimates for the minimal state space and for the underlying probability distribution. As a side product, the method of sieves yields a nice graphical tree representation for the potentially infinite dimensional minimal state space of the data generating process, which is very useful for exploration of the memory.

爱国主义教育应从民风民俗中加深民族认同感

爱国主义情感实际上就是民族认同感。我们不能指望从课堂中培养学生的民族认同感。应该从传统文化中、从生活实际中、从民风民俗中领悟中华民族的特征。通过旅游寻根、祭典祖先、解读家谱和考察节日,可以使青少年一代感受到强烈的民族认同感,以弥补学校教育的不足。     

面向广域网的服务发现机制

提出了一种新的用转发服务请求方法实现面向广域网的服务发现机制RFSD。分布在广域网中的服务器结点组成一个树结构,每个结点保存其父、兄弟和子等相邻结点的地址;服务请求传输报文中附加一定的转发信息。每个结点收到服务请求时,首先对其进行匹配操作,在满足的情况下响应服务请求,在不满足的情况下对附加信息进行处理,并将服务请求转发到某个相邻结点,这种方法可以有效地实现广域网中的服务发现。     

Urban forest and environmental inequality in Campos dos Goytacazes,Rio de Janeiro,Brazil

Social and spatial inequality regarding environmental resources and services is one of most complex issues affecting contemporary urban life. The objective of this research is to study the spatial distribution of trees in public areas in Campos dos Goytacazes, Rio de Janeiro, Brazil. This research presents data gathered in ten neighborhoods in Campos. These neighborhoods were split into three distinct groups using wealth levels. Data obtained include the number of trees and private gardens and tree species diversity per neighborhood street. Our results demonstrate that the wealthier neighborhoods have both the highest tree biodiversity and number of trees. In contrast, the poorer neighborhoods present a low biodiversity level and fewer tree species. Our results also showed that age of the neighborhoods was not a factor in explaining the number of trees in public spaces. Socioeconomic and education levels of the population seem to play a more causal on tree quantity and species diversity. This inequality stresses a problem with environmental justice, a characteristic of Brazilian cities intrinsically connected to urban sustainability.
