The increased relevance of social media in our daily life has been accompanied by efforts to manipulate online conversations and opinions. Deceptive social bots—automated or semi‐automated accounts designed to impersonate humans—have been successfully exploited for these kinds of abuse. Researchers have responded by developing artificial intelligence (AI) tools to arm the public in the fight against social bots. Here we review the literature on different types of bots, their impact, and detection methods. We use the case study of Botometer, a popular bot detection tool developed at Indiana University, to illustrate how people interact with AI countermeasures. A user experience survey suggests that bot detection has become an integral part of the social media experience for many users. However, barriers in interpreting the output of AI tools can lead to fundamental misunderstandings. The arms race between machine learning methods to develop sophisticated bots and effective countermeasures makes it necessary to update the training data and features of detection tools. We again use the Botometer case to illustrate both algorithmic and interpretability improvements of bot scores, designed to meet user expectations. We conclude by discussing how future AI developments may affect the fight between malicious bots and the public. 相似文献

The research reported on in this article explores the use of social media for work-related or professional purposes. In particular, it focuses on the perceptions and use of social media by academics in the UK. The purpose of the research was to explore the potential social media has to facilitate the changing landscape of higher education and support the individual academic in their role. Of particular interest is how specific social media tools are being used to enhance networking opportunities and contribute to career progression. The use of social media was explored in detail through interviews and a survey. Typical activities that are currently being undertaken were identified and user group profiles developed that articulate different levels of engagement with these tools and the motivations that each group of users have for using social media. The study found that, with increasing levels of activity, the number of motivations for using social media increase, as does the perceived number of successful outcomes, including contributions towards career progression. The main barriers to using social media were identified as a lack of time and skills to undertake these activities, as well as a negative perception of social media. Recommendations for increasing participation are to provide practical training, including the sharing of good practice, and to initiate dialogues within institutions regarding the potential career progression opportunities that social media may afford. 相似文献

This paper is concerned with the educational value of Facebook and specifically how it can be used in formal educational settings. As such, it provides a review of existing literature of how Facebook is used in higher education paying emphasis on the scope of its use and the outcomes achieved. As evident in existing literature, Facebook has been used mainly for social networking purposes through the establishment and collaboration of social groups in educational settings. However, a set of recent studies has exemplified how Facebook can provide an empowering means for achieving educational goals and supporting students develop crucial skills (e.g., writing, networking, collaborating) by serving as members in various learning communities. Concluding, we argue that Facebook can provide a valuable pedagogical tool that enhances student learning. Hence, future research towards further exploring Facebook’s use in educational settings is warranted for the purpose of producing scientific evidence about the ways in which Facebook could be utilized to enhance learning. 相似文献

This study examined the effectiveness of using a Facebook group to increase pre-service teachers’ knowledge of core technology topics. Further, it examined their use of Facebook, their use of a course-related Facebook group, their participation habits in the group, and their perceptions of using Facebook for educational purposes. Results revealed a significant gain in achievement as measured by scores on pre- and posttests. Additionally, Facebook was most frequently used to maintain existing relationships, to share photographs, and to communicate. The Facebook group was used to lurk/read, post comments, “like” comments, and post additional information. The pre-service teachers indicated that the Facebook group was beneficial in improving readiness for course assessments, was convenient, provided a good means of communication, and enhanced learning. 相似文献

Facebook has become one of the most popular social network sites among many students. However, current research on Facebook use has focused mainly on Anglo-American students. Relatively little is known about Facebook use in Singapore. Data were collected from 83 students (ages ranged from 15 to 23). This study uses a naturalistic case study wherein the students' decision to use Facebook is a personal decision and on a voluntarily basis; their participation is not a required or graded component. The specific objectives of the study are first, to examine Singapore students' motives for using Facebook; second, to investigate the types of friends they communicated with on Facebook; and third, to examine how students manage their privacy on the social networking site. Findings suggested that the current sample of Singapore students used Facebook primarily for non-educational purposes. Specifically, Facebook was used to maintain relationships with existing known friends such as former or current schoolmates. Respondents also reported using Facebook for entertainment purposes and to vent their emotions. No respondent reported using Facebook for educational purposes. The most common strategy for privacy protection utilized by the respondents was to decrease profile information visibility through restricting access to only known friends. Educational implications of the findings as well as suggestions for future research are provided. 相似文献

ABSTRACTBased on an ethnographic study, this article presents the class-based disparities of Chinese parents’ usage of WeChat, the dominating social networking mobile application in China, in their educational involvement. We find that middle-class parents are the privileged ones who have exploited the use of WeChat not only as a medium for communication, but more as a mode of influence. Through WeChat, their various forms of capital are channelled to catalyse changes in their children's education. In contrast, working-class parents tend to act as absent participants in using WeChat for their educational involvement. We argue that WeChat has brought forth the consequence of widening the arena for winning or losing at the educational game for parents from different social classes. We call for corrective policies and guidelines on the usage of WeChat and other SNSs technologies in home–school dynamics. 相似文献

In 2012, a research project was implemented to investigate the possibility and effectiveness of instituting a personalised and virtually networked mode of professional development to promote teacher confidence and competence with information and communications technology and its use as a key component of teachers’ pedagogy. The aim of the project was to examine an online mode of professional development where a network of teachers was built without any face-to-face contact and where the approach for professional development was personalised and self-directed. Six geographically dispersed schools in Queensland were involved, with 12 teachers participating over the school year supported by a mentor. Findings reveal that teachers operated in an independent manner, acknowledging community but taking from rather than contributing to the generation of co-created knowledge. Implications drawn from the case studies suggest that greater milestone-setting, multiple levels of leadership and special interest groups are required to support interaction between users and content while still maintaining an agile approach. 相似文献

在家庭与学校之间建立较为紧密的合作关系常被研究者和政策制定者视为一项积极的政策工具。但研究指出:家长——特别是来自农村地区的家长,参与学校教育的可能性较低。以一项持续时间较长的民族志调查为基础,对农村家长学校教育参与中的“关系化”策略的描述发现,由于正式的学校制度和组织关系总是镶嵌在更广泛的社会关系网络中,在受制度支持的组织关系本身结构性弱的情况下,其所蕴含的切事的非个人性的内容容易被私人关系的运作规则所替代。由于“关系化”策略本身往往意味着持续的投入,这导致一般农村家庭由于欠缺市场能力或基于理性计算而缺乏动机与教师保持联系,这完全可能成为重要的社会再生产工具。立足中国本土现实,在概念化方面尝试突破已有研究常采用的“强关系”、“弱关系”的两分法,强调关系本身的社会建构性,分析其可能的社会再生产效应,具有一定的理论和现实意义。 相似文献

This paper reports the results of the first academic study of the use of a major social networking website, MySpace, by children. The study examined the degree of, and reasons for, information disclosure by children in high schools in Sydney, Australia. Social networking sites such as MySpace are a huge Internet phenomenon, some with hundreds of millions of users and often the most visited Internet sites on a daily basis. They are particularly attractive to, and used by, children, perhaps eclipsing email as a preferred communications medium. This study shows that, by and large, children are acting responsibly in embracing this new technology, however, there are a significant number potentially at risk, possibly due to their lacking individual personal privacy values. The paper concludes with a call for parents and teachers to become more familiar with social networking and to help their charges understand the implications of its use. 相似文献

The social networking use of university and college counseling center (UCCC) mental health providers has not been widely researched. Most of the 20 providers surveyed in this preliminary study reported engaging in social networking despite identifying pros and cons to its use. Participants’ reported use of social media may indicate that social networking sites are used primarily to glean information. Risks associated with social networking for UCCC practitioners are discussed and implications for training and social media use are provided. 相似文献

This article explores the contrasting predispositions of a group of working-class and middle-class undergraduates to using nepotism to gain advantage in the labour market. Drawing upon a Bourdieusian framework, it is argued that the middle-class students, whose habitus was aligned to the field, were more likely to express a willingness to utilise whatever networks they could to secure a ‘foot in the door’. Meanwhile, the working-class students, who were more insecure about the legitimacy of their participation within a middle-class field, expressed a commitment to a form of honour which ruled out using contacts on the grounds that it was morally unacceptable. They discussed a desire to ‘prove themselves’ which is arguably symptomatic of a deeply ingrained reliance on meritocracy. I explore how this may arise due to their habitus having developed within a dominated position in society where respectability is crucial to generating feelings of self-worth and value. 相似文献
