基于线上线下混合式大班翻转的单片机教学改革

在电子行业迅速发展的背景下,单片机课程对学生的作用越来越重要,然而学生对单片机课程不容易学会并且没兴趣学,把自己当做观众不全力学,导致学生掌握的课程内容跟不上时代发展的步伐。提出了线上线下混合式大班翻转的教学改革思路,将线上自主学习和线下翻转教学相结合,学生通过网络平台自主学习基本理论;知识延伸部分以翻转课堂的形式在多媒体教室进行。使学生有针对性的学习,提高了学习单片机知识的积极性,通过师生取得的成果证明了该教学改革取得了一定的效果。

In Face on Facebook: Brooklyn's Drag Community and Sociotechnical Practices of Online Communication

Recently, Brooklyn has seen an explosion of drag culture, with dozens of performers taking the stage in any given week. Social media plays a vital role for members of this community, simultaneously allowing self‐promotion and community solidarity. Drawing on focus group interviews, we analyze the communication practices of Brooklyn's drag performers, examining both the advantages and drawbacks of social media platforms. Using conceptual frameworks of faceted identity and relational labor, our discussion focuses on affordances and constraints of multifaceted identity in online contexts and theories of seamful design. We contend that by analyzing online communication practices of drag performers, it becomes possible to identify gaps between embedded ideologies of mainstream social media technologies and the localized values of outsider communities.     

OSF:一种支持SaaS应用的构件框架

离线SaaS应用可以工作在时断时续的网络连接环境下,是一种环境可感知的智能SaaS软件.目前支持离线访问Web应用的研究成果较少,且其没有考虑到SaaS的特性,更没有形成构件化框架.为了解决上述问题,提出了离线SaaS框架OSF(Offline SaaS Framework),并给出了支持离线访问的面向操作的构件框架的结构和运行机制.通过案例描述验证了该构件框架的功能和性能.理论和实验表明,离线SaaS应用框架极大地改善了用户体验,保证了SaaS服务的可用性,扩大了SaaS的应用范围,同时还提高了系统开发效率.     

Is internet the cherry on top or a crutch? Offline social support as moderator of the outcomes of online social support on Problematic Internet Use

The study is part of a research whose goal is identifying what predictors determine either a positive or a dysfunctional use of Internet. The factor at stake is here social support. Specifically our study, carried out through an online questionnaire, hypothesized a moderation of Offline Social Support in the relationship between Online Social Support, Problematic Internet Use, and Life Satisfaction. The study found that while Offline Social Support reduces the chances of developing a Problematic Internet Use, Online Social Support increases them. Furthermore the data supported the moderation of Offline Social Support in the outcomes of Online Social Support: when the first is low, as the latter increases the Problematic Internet Use gets higher; when Offline Social Support is high, an increase in Online Social Support determines a decrease in Problematic Internet Use. By contrast the moderation of Offline Social Support on the relationship between Online Social Support and Life Satisfaction was not confirmed. Our research show that when investigating psychological constructs related to Internet activity these must be considered in their offline and online variations to provide an answer to the debate on psychological outcomes of undertaking social interactions in Internet land. Our results suggest that the usage of the Web may become dysfunctional when it is meant to compensate for lacks of the “offline life”.     

A control design and calibration reduction methodology for AFR control in gasoline engines

A control architecture for air to fuel ratio (AFR) control of gasoline engines designed to work with switching and/or wide range oxygen sensors, with the goal of minimizing calibration effort while meeting performance requirements, is described. A high bandwidth, dithered inner-loop reference tracking controller with pre-catalyst oxygen sensor feedback coupled with a low bandwidth setpoint tracking outer-loop with post catalyst oxygen sensor feedback, is used to control engine exhaust and O₂ storage in the three-way catalyst (TWC), respectively. A total synthesis inspired design ensures that significant non-linearity in the system is handled through a coordinated and corrective action and expected response blocks in the open-loop, without burdening the closed loop controller. Calibration is achieved offline, through closed loop optimization using genetic algorithms, while simultaneously meeting performance and stability criteria with significantly reduced need for in-vehicle tuning. Experimental results show comparable emissions performance with the stock OEM AFR controller under warmed up conditions over a standard drive cycle.

Who am I? Representing the self offline and in different online contexts

The present paper examines the extent to which self-presentation may be affected by the context in which is it undertaken. Individuals were asked to complete the Twenty Statements Test both privately and publicly, but were given an opportunity to withhold any of their personal information before it was made public. Four contexts were examined: an offline context (face-to-face), an un-contextualized general online context, or two specific online contexts (dating or job-seeking). The results suggested that participants were willing to disclose substantially less personal information online than offline. Moreover, disclosure decreased as the online context became more specific, and those in the job-seeking context disclosed the least amount of information. Surprisingly, individual differences in personality did not predict disclosure behavior. Instead, the results are set in the context of audience visibility and social norms, and implications for self-presentation in digital contexts are discussed.
