基于演化博弈的网络舆情传播的羊群效应研究*

鉴于我国的特殊国情和庞大的网民基数,网络舆情对现实社会的影响巨大,并获得广泛关注。羊群效应不仅会影响网络舆情的传播过程,还会影响舆情的最终演化方向。若不对网民群体内部的羊群效应加以引导,可能对社会稳定造成威胁;若政府积极利用,可以使舆情向政府期望的方向演化。为了更好地认识网络舆情传播过程中的羊群效应,将演化博弈理论引入该问题的研究中。首先对羊群效应中的网民、政府进行简要界定,然后分别就网民群体内部、网民和政府之间建立演化博弈模型,并根据模型得出相应的指导意义。最后对本文内容进行简要总结,并指出研究的不足之处和今后的研究方向。     

Service user and carer involvement in students’ classroom learning in higher education

The following article presents a small-scale qualitative study in which the student learning experiences from service user and carer (SUAC) involvement in social work, mental health nursing and social welfare courses at an English university were evaluated for any effects on student perceptions, knowledge, skills and practice. Using focus group methodology, student participants reported positive outcomes from exposure to SUAC classroom inputs such as a greater valuing of SUAC knowledge as expert knowledge, help with the development of empathy and an appreciation of constructive challenges to mainstream curricular delivery. Notes of caution were identified, particularly in respect of the sometimes unexpected levels of emotion displayed by SUAC presenters. Recommendations for meaningful SUAC involvement in higher education are made regarding the need to involve SUACs across the whole duration of a course; the need for the preparation of both students and presenters regarding boundaries; the fit of presentations with intended learning outcomes; more partnership delivery in classrooms between academics and SUACs (possibly with a differentiation between theoretical and practice inputs); the opportunities for SUACs to present their own situations as real rather than hypothetical case studies for students and the possibilities that may result from introducing a ‘buddying’ system between students and SUACs throughout their studies. It is suggested that the insights from this small-scale study merit further exploration on a larger scale if policy and practice in the field of service and user involvement in higher education are to move forward in an inclusive manner.

Assessing the Accessibility of Library Tools & Services When You Aren’t an Accessibility Expert: Part 2

Abstract

There are a few studies in library literature that explore accessibility issues from the perspective of students who use assistive technologies for accessibility. As we shared in part one of this two-part series in our column, librarians have extensively explored through usability studies with WAVE and other audit tools how accessible library websites and databases are when using assistive technologies like JAWS. In this column, we asked our blind student worker to journal his experiences navigating our library’s databases. We found this student navigated the databases better than we anticipated. While his experiences regarding the accessibility of the libraries’ electronic services varied, common issues he experienced included navigational issues from menus with expanding capabilities, documents that were not scanned with OCR, and images without alternative text.
