从三面向公司诉重庆市涪陵区图书馆一案看图书馆的链接服务

三面向公司诉重庆市涪陵区图书馆一案凸显了"一般链接"和"深度链接"的问题."深度链接"是否侵权,早在<信息网络传播权保护务例>出台之前便已进入了人们的视野.以"深度链接"为依据进行侵权认定,无论从司法解释还是司法实践上看都缺乏依据.本案启示图书馆,在提供链接服务时需要对被链接内容进行一定程度的筛选、调查;认真对待侵权通知,及时断开涉嫌侵权链接.     

Enhancing Knowledge Transfer in Classroom Versus Online Settings: The Interplay Among Instructor, Student, Content, and Context

This article integrates management education and organizational learning theories to identify the factors that drive the differences in student outcomes between the online and classroom settings. We draw upon theory on knowledge transfer barriers in organizations to understand the interlinking relationships among presage conditions, deep learning process, and product in the 3P model of student learning. We test our model in the context of undergraduate education and find that confidence in the instructor's expertise, perceived content relevance, and the social richness of the classroom learning environment enhance student enjoyment of the course. Confidence in instructor's expertise and perceived content relevance also contribute to greater understanding of causal relationships among course concepts. Enjoyment is positively associated with learning performance in the classroom, but not online, and student ability is positively associated with learning performance in the online context, but not in the classroom. Our results have implications for course designs in the traditional classroom context and the more innovative online environment.     

Deep transitions: Emergence,acceleration, stabilization and directionality

Industrial society has not only led to high levels of wealth and welfare in the Western world, but also to increasing global ecological degradation and social inequality. The socio-technical systems that underlay contemporary societies have substantially contributed to these outcomes. This paper proposes that these socio-technical systems are an expression of a limited number of meta-rules that, for the past 250 years, have driven innovation and hence system evolution in a particular direction, thereby constituting the First Deep Transition. Meeting the cumulative social and ecological consequences of the overall direction of the First Deep Transition would require a radical change, not only in socio-technical systems but also in the meta-rules driving their evolution – the Second Deep Transition. This paper develops a new theoretical framework that aims to explain the emergence, acceleration, stabilization and directionality of Deep Transitions. It does so through the synthesis of two literatures that have attempted to explain large-scale and long-term socio-technical change: the Multi-level Perspective (MLP) on socio-technical transitions, and Techno-economic Paradigm (TEP) framework.

从两地书看瞿秋白深爱杨之华的浪漫情怀

中国共产党早期革命领袖瞿秋白既有献身革命的高尚情操,又有钟情爱妻的缠绵柔怀。他在给夫人杨之华的信中,每每喜用“亲爱爱”“、好爱爱”“、乖爱爱”的昵称与“吻你万遍”等醉人心怀的温馨词语,感人至深。在信里,集中体现了他对爱妻杨之华刻骨铭心相思切、体贴入微关爱深、心心相印抚慰诚的纯正挚情,彰显了人性的至美境界,给人以坦诚而真实的温情脉脉与可亲可爱的形象,这与毛泽东、马克思等伟大人物的深厚的爱妻情结是一脉相通的,对当代社会的爱情、婚姻、家庭皆具有深刻的启迪意义。     

Effects of pH management during deep hypothermic bypass on cerebral oxygenation: alpha-stat versus pH-stat

Objective: There is a remarkable lack of scientific evidence to support the option to use alpha-stat or pH-stat management, as to which is more beneficial to brain protection during deep hypothermic CPB. This study examined cortical blood flow (CBF), cerebral oxygenation, and brain oxygen consumption in relation to deep hypothermic CPB with alpha-stat or pH-stat management. Methods: Twenty-two pigs were cooled with alpha-stat or pH-stat during CPB to 15℃ esophageal temperature. CBF and cerebral oxygenation were measured continuously with a laser flowmeter and near-infrared spectroscopy, respectively. Brain oxygen consumption was measured with standard laboratory techniques. Results: During CPB cooling, CBF was significantly decreased, about 52.2%±6.3% (P＜0.01 vs 92.6%±6.5% of pH-stat) at 15℃ in alpha-stat,whereas there were no significant changes in CBF in pH-stat. While cooling down, brain oxygen extraction (OER) progressively decreased, about 9.5%±0.9% and 10.9%±1.5% at 15 ℃ in alpha-stat and pH-stat, respectively. At 31℃ the decreased value in pH-stat was lower than in alpha-stat (29.9%±2.7% vs 22.5%±1.9%; P＜0.05). The ratio of CBF/OER were 2.0±0.3 in alpha-stat and pH-stat, respectively; it was kept in constant level in alpha-stat, and significantly increased by 19℃ to 15℃ in pH-stat (4.9±0.9 vs 2.3±0.4; P＜0.01). In mild hypothermia, cerebral oxyhemoglobin and oxygen saturation in alpha-stat were greater than that in pH-stat (102.5%±1.4% vs 99.1%±0.7%; P＜0.05). In deep hypothermia, brain oxygen saturation in pH-stat was greater than that in alpha-stat (99.2%±1.0% vs 93.8%±1.0%; P＜0.01), and deoxyhemoglobin in pH-stat decreased more greatly than that in alpha-stat (28.7%±6.8% vs 54.1%±4.7%; P＜0.05). Conclusions: In mild hypothermic CPB, brain tissue oxygen saturation was greater in alpha-stat than in pH-stat. However, cerebral oxygenation and brain tissue oxygen saturation were better in pH-stat than in alpha-stat during profound hypothermia. PH-stat strategyprovided much more oxygen to brain tissue before deep hypothermic circulatory arrest.

论英语移就的生成理据

移就属于一种超常规搭配的修辞方法。这种超常规搭配看似有违常理，实际有自己的生成规则。移就的生成规则主要体现在四个方面：1、以心理的重建为基础；2、依赖于句子的深层结构；3、修饰词与被修饰词之间相互关联；4、与新的语境相适应。     

也谈<<长恨歌>>的主旨

《长恨歌》有讽喻说和隐事说两类观点。从"以意逆志"的角度看,《长恨歌》主要是同情杨。李的爱情悲剧,同时也对李隆基的表现进行了揭露和谴责,是感伤诗而不是讽喻诗,更无关乎隐事。     

学习架构：深度学习灵活性表达

针对深度学习的灵活性诉求,研究尝试构建一种灵活的框架形式——学习架构。为此,研究从“架构”的词义以及其在建筑学领域与计算机科学领域的含义入手,经过两次探究分析并类比教学结构的定义提出了表征灵活性的学习架构界定。之后研究论述了三种现有学习架构模型,并从深度学习特征的角度进行解析,得出它们最多只能关注深度学习某方面特征的结论。基于这些认识,研究构建了一种能够表征学习任务、学习活动、学习进程、教学决策四方面灵活性的深度学习架构模型,并论述了其理念机制。希望研究能够加深学者对学习架构的认知,为深度学习的研究提供新方向。
