一个性能良好的图像水印算法

提出了一种性能良好的图像水印算法，该算法在嵌入水印时先对水印信息进行奇偶编码再嵌入到图像中，在提取水印时对恢复出的水印信息进行奇偶解码，实验结果表明，该算法比未采用奇偶编码的同一水印算法具有更好的不可见性和稳健性。

Using the theory of planned behaviour framework to understand Tasmanian dairy farmer engagement with extension activities to inform future delivery

Purpose: To identify and understand factors influencing farmers’ decisions to engage with extension activities. To understand farmer segments and how these factors vary in order to develop recommendations for future extension delivery.

Methodology: Qualitative data was obtained through semi-structured interviews with 30 Tasmanian dairy farmers. The Theory of Planned Behaviour (TPB) framework was used to identify and explore factors influencing farmer engagement intentions and behaviour.

Findings: There was a negative effect of social influence on experienced farmers’ intention to re-engage with extension, due to the belief extension activities were targeted to less experienced, younger farmers. Perceived control factors limiting engagement included lack of confidence about existing knowledge, resulting in farmers perceiving extension activities as confronting.

Practical implications: Key factors influencing intention to engage and continued engagement with extension were identified. These findings will inform future design and targeting of extension activities to improve initial and continued engagement. Subsequent recommendations are presented.

Theoretical implications: Previous TPB studies on adoption as an outcome of extension have typically focused on quantifying adoption predictions, rather than exploring how social factors interact and influence intentions and behaviours. This paper demonstrates how the TPB can be qualitatively applied to better understand farmer decision making, in this instance with respect to their initial and continued engagement with extension.

Originality/value: This paper demonstrates how the TPB can provide an evidence-based framework to qualitatively explore farmer intentions and behaviour. This approach has led to new insights into farmer decision making that will inform improvements in future extension development.     

浅谈中国本土文化对现代设计的影响

现代设计越来越认同本土化。本土化是对本土文化的认同．而不是对符号或图形的认同。探索本土文化的内涵．找出传统文化与自己个性的碰撞点，形成自己的设计风格，这才是设计本土化的精髓所在。

学会明确概念--语文教学思维训练之一

思维训练应遵循思维规律。中学语文教学思维训练的一项重要内容就是学会明确概念 ,亦即明确概念的内涵和外延。而下定义、对比 ,解说与描写、划出与分类、限制与概括都属于明确概念的方法。     

Validity extension of the Course-Faculty Instrument (CFI)

The Course-Faculty Instrument (CFI) demonstrates similar measurement properties with student populations at four diverse institutions. These students agree about the nature and extent to which course and instructor attributes relate to their learning. The results suggest that: (1) a perceived learning criterion may have general relevance to students, and (2) validity extension research is an economically feasible alternative to full-scale instrument development and validation efforts. Since validity extension is practical and facilitates cross-institutional comparisons, it appears to be a more viable strategy for researching and instituting student evaluation systems than is suggested by its current usage.
