Compensation paradox: the influence of monetary rewards on user behaviour

Many e-commerce companies collect users’ personal data for marketing purposes despite privacy concerns. Information-collecting companies often offer a monetary reward to users to alleviate privacy concerns and ease the collection of personal information. This study focused on the negative effects of monetary rewards on both information privacy concerns (IPC) and information disclosure. A survey approach was used to collect data and 370 final responses were analysed using a two-way analysis of variance and a binomial logistic regression model. The results show that monetary rewards increase IPC when an information-collecting company requires sensitive information. Additional results indicate that building trust is a more effective way of collecting personal data. This study identifies how organisations can best execute information-collection activities and contributes additional insights for academia and practitioners.

A motivational model of rural students' intentions to persist in, versus drop out of, high school.

Using self-determination theory, the authors tested a motivational model to explain the conditions under which rural students formulate their intentions to persist in, versus drop out of, high school. The model argues that motivational variables underlie students' intentions to drop out and that students' motivation can be either supported in the classroom by autonomy-supportive teachers or frustrated by controlling teachers. LISREL analyses of questionnaire data from 483 rural high school students showed that the provision of autonomy support within classrooms predicted students' self-determined motivation and perceived competence. These motivational resources, in turn, predicted students' intentions to persist, versus drop out, and they did so even after controlling for the effect of achievement.

A connectionist implementation of the theory of planned behavior: Association of beliefs with exercise intention.

The theory of planned behavior suggests attitudes are a product of salient beliefs. This study examined whether aggregating salient beliefs was plausible within a more biologically centered information-processing environment. A neural network was used to examine associations among beliefs relating to exercise intention. Data on intentions and behavioral, normative, and control beliefs from 114 respondents were used to train (by error backpropagation) a neural network to associate beliefs with intention. The R2 between the network's estimated and self-reported intention was .66. The network's representation comprised 6 belief profiles associated with high, moderate, or low behavioral intention. The neural network accommodated complex relationships among beliefs and belief-intention associations and indicated how high-level constructs such as attitudes may be viewed as the best fit (compromise state) between aroused beliefs.

基于样本熵与时频分析的手部抓握运动意图预测

针对上肢外骨骼控制信号产生与外部设备响应存在时间滞后导致脑机接口(BCI)系统实时性差的问题,采集被试手部自主抓握前运动相关皮质电位(MRCP) ,提出基于非线性复杂度特征样本熵 (SampEn)与线性幅值特征融合算法的手部运动意图预测方法. 从时频、神经复杂度分析不同大脑状态之间存在的差异,通过特征融合实现对手部抓握运动意图的预测. 基于特征融合意图离线预测准确率最高可达88.46%,可以在人体手部自主运动发生时刻?1 400 ms实现对手部运动预测. 与平静时期手部静止状态相比,被试产生手部抓握运动意图时脑电信号的功率谱与复杂度均产生明显变化,为基于手部运动意图预测提前驱动机器人实现人机协同提供控制策略.

明清家具雕刻与传统绘画造型相似性研究

中国传统雕塑和传统绘画都是历史上最具有魅力的两种艺术形式,也是素材和品种最为繁多的艺术,两者有很多方面是相融相通的,其中又以木雕,尤其是明清家具木雕与绘画最为相似。文章将通过对明清家具和传统绘画的客观比较,得出两者在造型方面的相似之处,这种互通性对当今新中式家具及发展当代家具雕刻有着积极的现实意义。     

潜在网络购物者与有经验者购买意愿比较研究*

感知风险和信任缺失被认为是阻碍网络购物发展的主要因素。以技术接受模型为理论基础,将感知风险和信任引入模型,把消费者分为潜在网络购物者和有经验网络购物者两大类,采用结构方程模型方法对影响我国消费者网络购物意愿的因素进行实证对比研究。实证结果表明：消费者感知网络购物有用性对其购买意愿的影响路径系数高于信任和风险因子对购买意愿的路径系数;感知风险对网络购买意愿有直接的负向影响;对于潜在消费者群体,信任显著影响其网络购物意愿,但对有购物经验的消费者群体信任却对网络购买意愿没有显著影响。     

魏晋文人审美情感对当代生存困境的启示

魏晋名士崇尚"自然"而行为"放达",不甘被儒家礼法束缚。在"礼崩乐坏"的大背景下,文人士大夫从道家文化中汲取营养,以摆脱当时趋于僵化的世俗儒家礼法的束缚,出现了"人的自觉"。魏晋时期的"人的自觉"产生的背景与当代人的生存困境有某种程度上的相似,但是当代人缺失了魏晋时期的一种审美情感,这也是当代人无法摆脱精神痛苦的根源所在。通过美育重新建筑起普遍的审美情感,使国人用一种审美的眼光看待生活,用一种审美的方式来经营生活,是改变当代人生存困境的有益探索。     

王弼“得意忘言”思想的诠释学意蕴

王弼解《易》,依据＂言不尽意＂和＂立象尽意＂的思想,合儒、道二家之精神,首唱＂得意忘言＂,将其作为一种重要的诠释方法纳入到人们的视野之中。这一诠释方法的提出,不仅从认识论角度有助于对＂言＂、＂象＂、＂意＂三者关系的合理阐释,而且它与＂有无互训＂等原则结合在一起奠定了＂以无为本＂的玄学本体论体系之基础。王弼＂得意忘言＂的思想虽然有不成熟的方面,但是却蕴含着丰富的诠释学意蕴,在中国古代诠释传统的形成和发展中占据着不容忽视的地位。
