Using Markov Chains for Non-perennial Daily Streamflow Data Generation

The use of Markov chains to simulate non-perennial streamflow data is considered. A non-perennial stream may be thought as having three states, namely zero flow, increasing flow and decreasing flow, for which a three-state Markov chain can be constructed. Alternatively, two two-state Markov chains can be used, the first of which represents the existence and non-existence of flow, whereas the second deals with the increment and decrement in the flow for periods with flow. Probabilistic relationships between the two alternatives are derived. Their performances in simulating the state of the stream are compared on the basis of data from two different geographical regions in Turkey. It is concluded that both alternatives are capable of simulating the state of the stream.     

《晋察冀日报》国际报道的现代启示

<晋察冀日报>及其前身<抗敌报>是我党在华北日本侵略后方各根据地中创办最早的一个党报.以这份报纸为例,可以管窥在60年前特殊的历史背景之下,根据地报纸报道国际重大事件的运作步骤.尤其是在第二次世界大战中欧洲战场胜利的出色报道中,根据地报纸积累了丰富的经验,为今天我们的大众媒体提供了珍贵的启示.     

伊斯兰教与新疆维吾尔族女性社会生活调查研究

文章在文本分析和实地调查基础上,从日常生活、婚礼葬礼和家庭教育三个方面分析了伊斯兰教对维吾尔族女性社会生活影响。调研结果发现伊斯兰教与维吾尔族女性的衣食住行、交往、婚礼葬礼、知识结构和道德品质等各方面都有紧密的联系,伊斯兰教在促进夫妻和睦、家庭幸福、社区和谐等方面都可发挥积极作用。深入研究此问题不仅有助于维吾尔族女性更加清晰认识本民族的传统和文化,还可进一步增进其他民族对维吾尔族的了解。     

略论延安《解放日报》的广告特色

延安时期的《解放日报》刊发过大量广告,这些广告从新闻之外的角度,为读者提供政治、经济、生活等信息,为边区经济建设做出了贡献。它们不仅是解放区广告的重要组成部分,而且也构成中国广告史重要的一页。这些广告内容丰富、形式多样、特色鲜明,尤其是本真、诚信的广告特色,对今天的广告业仍然具有较强的现实意义。     

“六报联合特刊”存废及其新闻史学意义再析——兼对李时新先生商榷的回应

1934年的＂六报联合特刊＂是上海日报公会协调其会员报共同应对元旦春节期间假日报业市场激烈竞争的产物,其存废是上海日报公会前期协调成功后期协调失败的表现,史量才在协调中扮演了重要角色。＂六报联合特刊＂的存废表明,20世纪30年代的上海报界是竞争强度有所减缓、合作有所增强的错综复杂的竞合态势。

Ma system identification using higher order cumulants application to modelling solar radiation

The main goal of this investigation is to elaborate an accurate and efficient algorithm able to estimate the moving average (MA) parameters in noisy environment. So, we address the problem of estimating the parameters of a MA--non-minimum phase (NMP)-system from the output observation when the system is excited by an unobservable independent identically distributed (i.i.d.) sequence. A new procedure, based on third and fourth order cumulants, to estimate the parameters of MA process when the order is known, is presented. This procedure was tested for various examples of MA (NMP) system, and for different order and different signal-to-noise-ratio (SNR). A comparison with some existing methods was also performed and the result shows the efficiency of the proposed algorithm. For validation purpose this method is used to search for a model able to describe and to predict the data set representing the daily solar radiation.     

Moderators of the relationship between daily work stressors and mood

Consistent with recent data showing a relationship between daily stress and mood, the authors investigated whether job specific factors would moderate the relationship between daily work stress and daily mood. Forty-three subjects from one teaching hospital initially completed questionnaires assessing the hypothesized moderator variables (emotional and informational support from the supervisor, job involvement, co-worker satisfaction, supervision satisfaction, and satisfaction with the meaningfulness of work). Thereafter, they completed questionnaires at the end of each workday assessing the number and negative perception of daily work stress and daily mood. After controlling for the effects of the different number of days for which data were available for each subject, the results showed that job involvement and all three facets of job satisfaction (supervision, co-worker, and work itself) moderated the relationship between the negative perception of daily work stress and mood. Neither emotional nor informational support from the supervisor moderated this relationship. Likewise, none of these variables moderated the relationship between the number of daily work events and mood. The results are discussed in terms of further research on daily work stress, and expanding and refining the focus on moderator variables.     

以社会史眼光看《申报》与上海近代商人的历史性关联

商人文化在历史的形成中,是以碎片化、不连续性、不完整状态呈现的.且在商人内部,观念、意识又是分裂的.而<申报>的运作是一个活生生的、积极的过程,它形式上是美查兄弟所有,但从它的产生、成长过程来看,又是中国近代上海社会自身发展的产物.近代中国上海的社会文化生产,就是通过<申报>所掀动的上海舆论和与此舆论互动的受众双方的经验元素建构起来的.
