永久在线、永久连接:移动互联网时代的生活方式及其影响因素

随着移动互联网的发展,"永久在线、永久连接"成为当代受众的新生活方式,也挑战了传统的受众与效果研究范式。本文从理论上阐释"永久在线、永久连接"概念,并运用一个全国性的随机抽样调查数据,首次实证描述中国受众"永久在线、永久连接"的行为与心理现状,并分析其影响因素。研究发现:移动互联网的技术可供性显著正向影响永久在线与连接行为,价格敏感、时尚国际、积极进取、稳定悠闲等生活方式对永久在线与连接具有不同方向的显著影响,错失恐惧对"永久在线、永久连接"的行为及心理均有显著的正向影响。本文在此基础上对研究的理论与实践意涵进行了讨论。     

The Relation of Mild Traumatic Brain Injury to Chronic Lapses of Attention

We assessed the extent to which failures in sustained attention were associated with chronic mild traumatic brain injury (mTBI) deficits in cognitive control among college-age young adults with and without a history of sport-related concussion. Participants completed the ImPACT computer-based assessment and a modified flanker task. Results indicated that a history of mTBI, relative to healthy controls, was associated with inferior overall flanker task performance with a greater number of omission errors and more frequent sequentially occurring omission errors. Accordingly, these findings suggest that failures in the ability to maintain attentional vigilance may, in part, underlie mTBI-related cognition deficits.     

朱熹“诚意”思想探微——以朱熹“心主性情”观为背景

＂诚意＂作为儒家基本修养工夫之一,其内涵在朱熹以＂心主性情＂观为核心的心性论中得到进一步的阐发和完善。文章通过分析＂诚＂、＂意＂以及相关文本认为,其含义包括道德活动中动机的纯粹性和意志的坚决性,以及内化道德意识为道德责任感的过程和时时提撕此心保持精神动力的作用。而诚意与致知、正心的关系以及此在工夫修养中的地位也就一目了然。     

The influence of exercise-induced fatigue on cognitive function

Abstract

Although anecdotal reports suggest that information processing and decision making is impaired immediately following prolonged periods of physical activity, results obtained from laboratory studies of exercise-induced fatigue have been inconsistent. Fatigue effects may be task specific and related to the time of post-exercise testing. The present study examined the effects on adults' performance of two cognitive tasks that differed in processing demands over an 80-min period of fatigue. Thirty young adult men and women were randomly assigned to either an exercise group and completed a 60-min bout of cycle ergometry at 90% ventilatory threshold or a control group and rested for 60 min. Following interventions, each participant completed a simple and complex version of a visual perceptual discrimination test, a 40-min memory-based vigilance test and a repetition of the visual perceptual discrimination tests. Those who exercised evidenced significant decrements in performance on complex perceptual-discrimination tasks compared to participants who rested. The response time of exercisers during a memory-demanding vigilance test were significantly slower than those of participants who rested; however, detection performance did not differ between groups neither was there a decrease in target detection across the vigil. The effects of exercise-induced fatigue may be task specific, with greater effects on perceptual tasks, which involve relatively automatic processing, compared to effortful memory-based tasks.

社会网络、先前经验与新生代农民工创业——基于河南省新生代农民工创业调查数据的分祈

个体的社会网络结构决定着其所能摄取的信息的数量与质量,而先前经验在很大程度上影响着其对信息的解读。利用河南省433份新生代农民工创业调查数据,考察新生代农民工社会网络与创业之间的关系,并探讨新生代农民工创业者先前工作经验对该作用过程的影响,研究发现：社会资本越丰富、社会网络越发达的新生代农民工,创业的概率越大;新生代农民工最后工作工龄、换工作次数在其社会网络与创业行为之间起着正向调节作用。应重视创业信息与知识的交流渠道建设,以使更多有创业意愿的新生代农民工个体辨识更具价值的创业机会。
