遥远未来和附近未来的自我表征述评     

李春芳 《赣南师范学院学报》2013,(1):119-121

解释水平理论认为,时间距离改变人们对事件的心理表征方式,进而改变人们对未来事件的反应。遥远的时间透视使得人们将注意力集中于核心的、有典型特征的自我,促进理想自我的表达。附近的实际透视将人们的注意力转向外部的情景,激活实际的自我。对于儿童和青少年来说,未来是自我概念的一种重要成分,从时间的角度研究自我表征对儿童和青少年形成健康、稳定的自我概念有重要的意义。  相似文献   

Near Field Communication: Introduction and Implications     

《Journal of Web Librarianship》2013,7(3):186-207

Near field communication is an emerging technology that allows objects, such as mobile phones, computers, tags, or posters, to exchange information wirelessly across a small distance. Though primarily associated with mobile payment, near field communication has many different potential commercial applications, ranging from marketing to nutrition, transportation, gaming, and health care. In libraries, near field communication could enhance outreach and existing services such as self-checkout. More importantly, near field communication also serves as a new way to link physical materials with digital information, potentially transforming the way users interact with the information environment. This introduction to near field communication will address its background and functionality, its current and anticipated commercial applications, and its potential effect on libraries, librarians, and library patrons. The authors of the article will also discuss the time frame for mainstream adoption, and the privacy and security concerns of this new technology.  相似文献

The effects of 4 weeks normobaric hypoxia training on microvascular responses in the forearm flexor

Intermittent exposure to hypoxia can lead to improved endurance performance. Currently, it is unclear whether peripheral adaptions play a role in improving oxygen delivery and utilization following both training and detraining. This study aimed to characterize skeletal muscle blood flow (mBF), oxygen consumption (mV?O₂), and perfusion adaptations to i) 4-weeks handgrip training in hypoxic and normoxic conditions, and ii) following 4-weeks detraining. Using a randomised crossover design, 9 males completed 30-min handgrip training four times a week in hypoxic (14% FiO₂ ~ 3250m altitude) and normoxic conditions. mBF, mV?O₂ and perfusion were assessed pre, post 4-weeks training, and following 4-weeks detraining. Hierarchical linear modelling found that mV?O₂ increased at a significantly faster rate (58%) with hypoxic training (0.09 mlO₂·min^?1 · 100g^?1 per week); perfusion increased at a significantly (69%) faster rate with hypoxic training (3.72 μM per week). mBF did not significantly change for the normoxic condition, but there was a significant increase of 0.38 ml· min^?1 · 100ml^?1 per week (95% CI: 0.35, 0.40) for the hypoxic condition. During 4-weeks detraining, mV?O₂ and perfusion significantly declined at similar rates for both conditions, whereas mBF decreased significantly faster following hypoxic training. Four weeks hypoxic training increases the delivery and utilisation of oxygen in the periphery.  相似文献

云南烟区原料差异化烟叶的质量评价及近红外检测技术在烟叶收购中的应用初探     

徐洁  彭漫江  常寿荣  罗华元  饶智  王胱霖  李伟  朱海滨 《昆明师范高等专科学校学报》2010,(6):10-13

2007-2009年通过对烟叶差异化的综合分析研究,差异化原料核心基地所产烟叶的内在化学成分、感官质量和致香成分均好于非差异化基地上所产烟叶.烟叶的感官质量与化学成分含量符合云南中烟工业标准,工业可用性高,是具有品种和生态双重特色的差异化烟叶,可供云产一、二类特色卷烟的原料需求.近红外检测技术可用于烟叶收购时的内在质量检测,所建数据库能为叶组配方设计提供理论与数据支撑.  相似文献
