Mic Check: Occupy Wall Street and the Space of Audition

As used by Occupy Wall Street, the human microphone played a central role in the formation of an auditory space that was animated by the principles of direct democracy that guided the movement. However, the practice also allowed the occupiers to confront and subvert the monopoly on amplified public speech that the government of the City of New York had possessed for nearly eighty years. This paper presents a brief history and analysis of the city's regulation of sound devices, locating the human microphone in a larger struggle over the rights to public speech and assembly.     

Perceptions of parental substance use disorders in cross-system collaboration among child welfare,alcohol and other drugs,and dependency court organizations

Cross-system collaboration among child welfare (CW), alcohol and other drugs (AOD), and court organizations shows promise in addressing the many needs of CW-involved families experiencing parental substance use disorders (SUDs). Research has suggested that differing perceptions of parents with SUDs among staff in these organizations may hinder the collaborative process. Using a sequential explanatory mixed-method approach, this study explored staff perceptions of parental SUDs among CW, AOD, and court organizations. Logistic regression analyses indicated that, compared to CW respondents, AOD respondents were: (a) less likely to believe that parents could provide effective parenting; (b) more likely to believe that abstinence should be a criterion for reunification; (c) more likely to agree that parents should receive jail time as a consequence for noncompliance with court orders; and (d) more likely to believe that parents could succeed in treatment. Thematic analyses of these focal areas identified two core themes (focus on the primary client and mandated time frames for permanency), as well as multiple subthemes, that provided a nuanced understanding of differing perceptions on these matters. Suggestions for the development of anticipatory cross-system training and practices and implications for policy evaluation are discussed.     

Adapting an Embedded Model of Librarianship,College by College

Librarians are increasingly moving out of the library and into the wider university setting as patrons spend more time seeking information online and less time visiting the library. The move to embed librarians in colleges, departments, or customer groups has been going on for some time but has recently received more attention as libraries work to find new ways to reach patrons that no longer need to come to the physical library. Few universities have attempted to embed all their librarians. This case study describes how one group of health sciences librarians dispersed its professional staff throughout its campuses and medical centers.     

“一国两制”：马克思主义学说与中国特色社会主义道路的双重逻辑

“一国两制”的实践发展史,也是一部马克思主义与中国特色社会主义道路相结合的理论探索史。16年的伟大实践积累了十分宝贵的经验,坚定了中国特色社会主义道路的理论自信与制度自信。因此,对“一国两制”基本方针的认识与评价,必须从国情与时代的发展中来探寻演进的逻辑。它的成功体现了我党在处理国家内部问题时坚持原则性与灵活性的统一,适应了生产力与生产关系的发展规律,用实践丰富与拓展了马克思主义国家学说在中国的当代论域。

《立体构成》课程教学的改革与探索

成人高校的立体构成教育,大多数情况下兼具有基础教育和高等教育双重性质;以学生自主学习为主的教学模式,未必适用于成人高校的立体构成教学。本文在分析成人高校的学生特点和立体构成的课程特点的基础上,提出建立适合成人高校特点的、复合式的“一课两制”教学模式,积极开展全方位、多层次的互动式教学,以适应成人高校立体构成课程教学的特殊需要。
