基于混沌特性的小波数字水印算法研究

为了提高水印信息的隐藏性和安全性,基于混沌序列的优良特性,本文提出了一种用于图像数字水印嵌入和检测的算法。由于混沌序列对初值具有敏感性,攻击者很难从一段有限长度的序列推断出整个混沌序列的初始条件,因此可保证水印信息的安全性。嵌入水印后的图像具有很好的不可见性,并且对常见的信号处理和噪声干扰具有较好的鲁棒性。     

基于委托代理模型的二手房投资者和中介公司的关系研究

服务业的发展与劳动分工的演进

技术进步源于劳动分工,分工具有自发演进的正反馈机制。技术进步能够导致报酬递增的结果,所以分工的演进才是经济可持续增长的决定性因素。作为分工演进的自然结果,服务业在经济活动中起着重要甚至是核心的作用。发达的服务业已成为劳动分工深化和技术进步的前提和条件。

某电厂超滤膜污染分析及离线化学清洗

针对某电厂超滤膜组件运行后出现膜污染的现象,通过检查膜组件运行时的水质分析、SEM扫描分析和能谱分析寻找造成污染的原因,证明超滤膜组件的污染物是有机物和胶体,为此,采取离线化学清洗,以先采用碱洗,后酸洗的方式,使膜性能得以恢复,并对此后超滤装置的维护提出有效的建议.     

Social media use in the career development of graduate students: the mediating role of internship effectiveness and the moderating role of Zhongyong

This paper proves that social media use can contribute in important ways to employability outcomes. Specifically, results from a survey of 196 recent graduate students in China indicate that social media use is positively related to employability skills. Internship effectiveness serve as a mediating mechanism through which social media use affects employability skills. Zhongyong has a moderating effect on the social media use-internship effectiveness relationship. In addition to the direct moderating effect, Zhongyong is found to moderate the indirect relationship between social media use and employability skills. We discuss implications of these results for research and practice.     

Teacher Beliefs in Action: A Cross-Sectional,Longitudinal Follow-Up Study of Teachers' Personal Practical Theories

Based on a cross-sectional, longitudinal follow-up study of graduates from our master's-level elementary education program, in this article we examined changes in espoused beliefs elicited in the form of personal practical theories (PPTs) of three graduates with 2, 4, and 6 years of experience teaching in the same partnership school where they did their student teaching. We compared their original PPTs collected during their teacher education program with their current PPTs elicited in follow-up interviews, and then observed their classroom practices. Case summaries of these teachers are presented, and analysis and implications focus on changes in their PPTs, how their PPTs played out in their classrooms, and perceived barriers and supports to enacting their beliefs.
