Cognitive Aging and Computer-Based Instructional Design: Where Do We Go From Here?

In this article, themost relevant literature on cognitive aging and instructional design is merged to formulate recommendations for designing computer-based training material aimed at elderly learners. The core message is that researchers and instructional designers do not need to develop special computerized instruction for older adults. Rather, existing principles of general instructional and multimedia design can be evaluated and used to accommodate the needs of elderly learners. Particular attention is given to John Sweller’s Cognitive Load Theory (CLT) and Richard Mayer’s Cognitive Theory of Multimedia Learning (CTML). It is argued that these instructional theories bear important benefits for older learners because they support an efficient use of available cognitive resources. New research directions are suggested to test the implications of these theories for learning in old age.

从朝省诗看姚合的盛唐情结

学界一般认为姚合的诗风比较浅近平淡,姚合本人的心态也比较安闲和消沉。不过,姚合还有较为积极的一面,并且还有浓重的盛唐情结。从姚合的朝省诗中,可以寻找到他的这种盛唐情结。     

Modular designs and integrating practices: Managing collaboration through coordination and cooperation

Collaboration in large-scale projects introduces challenges involving both coordination (the ability to collaborate) as well as cooperation (the willingness to do so). Existing research has shown how modular designs can improve coordination by locating interdependencies within rather than between different modules. Based on an in-depth case study of collaboration in a large-scale infrastructure project, our study highlights an effect of modularity on collaboration that previously has been overlooked. Specifically, we show that while modular designs may help overcome coordination challenges by reducing interdependencies between modules, they can in turn hamper collaboration by emphasizing specialization within modules. Therefore, though existing work typically perceives modularity and integration as opposites, we clarify how they can also act as complements. In particular, we show how firms need to complement modular designs with integrating practices that stimulate cooperation. Overall, we contribute to the literature on collaboration and modularity by explaining when and how organizations can combine modularity and integration.     

知识转移视角下复杂产品产学研协同创新管理机制研究

复杂产品协同创新是一项复杂的系统工程,具有研发周期长、系统组成复杂、技术难度和投资风险大等特点,传统管理模式很难满足其产学研协同创新的要求,需要科学、合理的管理机制作为保障。以知识转移为视角,从关系契约管理和非正式网络管理两方面设计了复杂产品产学研协同创新的管理机制,提出关系契约管理和非正式网络管理在复杂产品产学研创新活动中会协同发生作用,能有效促进创新主体间显性知识和隐性知识的转移,保证产学研协同创新活动的顺利进行。

“恋父”与“审父”——论20世纪90年代女性成长小说中的父亲文化形象

具有“慈爱”和“禁止”双重功能的父亲文化形象,使女性在成长过程中常常陷入“恋父”与“审父”的情感纠葛中。这种复杂矛盾的心态显然与成长男性对父亲的超越有着不同的意义。女性成长历程中纠缠着的父亲情结以及这一情结给女性造成的成长创伤,反映了现实历史中女性依然笼罩在父权阴影中,因此,女性要实现主体和自我的确立,就必须用理性力量破解和抗衡被父亲权威及其所代表的父权统治所宰制的命运。
