This essay explains how ethnography of communication informed a model of public participation designed to engage underserved populations in culturally sensitive deliberative discussions. Community college students successfully served as coresearchers to pilot test and assess the effectiveness of a community-service learning model of civic engagement research. 相似文献

Approximately 25% of Americans volunteer annually (Bureau of Labor Statistics, 2011). As organizational members, they face uncertainty concerning their roles, their relationships, and their organizations (Kramer, 2004). Volunteers likely face different uncertainty management issues than employees who have been the focus of most previous research. Volunteers have a different psychological contract and different motivations than employees (Rousseau, 1990). This study examined issues of uncertainty management of volunteer members in a particular setting, a community choir. In particular, it found that supervisor and peer communication and other internal factors, such as more preparation time and less difficult tasks, were associated with higher levels of certainty for members of a community choir. In addition, higher levels of certainty and additional external factors such as family support for participation and lack of conflicts were associated with higher levels of satisfaction and identification and a greater willingness to recruit for the organization. Results have implications for improving communication to increase volunteers' certainty and increasing their voluntary participation in organizations. 相似文献

Non-governmental organizations (NGOs) are deeply embedded within the socio-political landscape of India. NGOs were instituted by the Indian government specifically for the purpose of nation-building at the time of national independence in 1947 (Muttalib, 1987). In recent times however, NGOs have come under much scrutiny because of the expanding neoliberal agenda, and global discourse surrounding NGOs often involves questions of accountability. Communication scholars have studied NGOs in various contexts, but what remains unexplored is the question of how NGOs are portrayed within the media, which in contemporary society constitutes the public sphere or space of public opinion. It is important to look at the media because public legitimacy can have serious consequences for an NGO's ability to garner funds, influence policy, and build trust in beneficiary communities. This study thus asks the research question: How are NGOs framed in the Indian media? A qualitative analysis was employed to identify news frames or ‘interpretive packages’ used to talk about NGOs in two of the most widely-circulated English daily newspapers in India. The analysis identified four frames: the ‘do-good’ frame, protest frame, partner frame, and the public accountability frame. The findings show that, for the most part, NGOs are represented in a positive and even a nationalistic light, in spite of the larger global discourse interrogating NGO practices. The discussion elaborates on institutional, political, and historical reasons why NGOs are portrayed favorably in the newspapers. 相似文献

To meet the rapid evolution of visual media and changing patron expectations, Brigham Young University's Harold B. Lee Library created Byugle, a device to stream videos to their users. This article describes the new challenges streaming video creates for librarians and the cooperative efforts of subject librarians, technical services, and the Information Technology Department as they work together to meet these challenges to provide streaming media for their patrons. 相似文献

Meeting the challenge of program accountability is a goal for teacher education programs across the USA. In this context, achieving effective assessment practices that provide concrete evidence of program participants’ knowledge and skills has become both an increasingly significant issue and a challenge to teacher education programs seeking to document the attainment of their program learning outcomes. This qualitative study examined the portfolio reflections of 51 teachers enrolled in an advanced master’s degree program whose learning outcomes are aligned with the core propositions of the National Board for Professional Teaching Standards. Using the four levels of reflection and a fifth level that emerged from data analysis, we examined the levels of development and change in teachers’ reflections across the program. This analysis helped the researchers to determine to what degree teachers developed a reflection‐based inquiry stance in their classrooms during the program. The study contributes new findings to the body of literature on the role and function of portfolios in teacher education programs seeking to document teachers’ understanding and application of specific program goals and professional standards as a result of professional development coursework. As an authentic assessment tool, portfolio data (i.e., evidence such as the reflections contained therein) can provide an important lens for capturing teachers’ approach to teaching and learning and provides insight into the complexity of professional development for practicing teachers. 相似文献

ABSTRACTThis holistic single-case study reports on the benefits mentors derived from participating in the Increasing Minority Presence within Academia through Continuous Training (IMPACT) mentoring program. The IMPACT program was sponsored by the National Science Foundation Office for Broadening Participation in Engineering 15–7680 (awards #1542728 and #1542524). In this program, emeriti faculty were matched with underrepresented minority faculty in the engineering professoriate for career-focused mentorship. The conceptual framework of the Benefits of Being a Mentor grounded this study. Findings indicate mentors appreciate the opportunity to give back and remain engaged in the field, to relive past academic career experiences, and to support the next generation of engineering professors while adjusting to retirement. These findings aligned with the conceptual framework on three factors: rewarding experience, improved job performance, and generativity. Implications for administrators and faculty, as well as additional research areas, are discussed. 相似文献

The purpose of this mixed research study was to examine mentoring experiences specific to grade span through the perspective of principals, mentors, and mentees. An instrument containing items on demographics, administrative support, and mentoring program components was administered to first-year teachers (n?=?998), mentors (n?=?791), and principals (n?=?73). Mentors’ attitudes towards mentoring were statistically significantly more positive than were the mentees’ attitudes, although, on average, the attitudes for both groups were positive. A statistically significant difference in attitudes emerged as a function of grade span, with elementary school mentees reporting the highest levels of motivation to be mentored and the greatest desire to observe veteran teachers. Qualitative analyses revealed that mentoring includes specific format, better matches, increased time for mentoring, observation opportunities, and better training for mentors. Implications are discussed. 相似文献

ABSTRACTA central tenet of the open data movement is that, to the extent permitted by law, data—especially data collected or produced by government agencies—should be published without restrictions on access or reuse. Proponents of open data believe that unrestricted access to raw data yields many benefits to society, including increased organizational transparency, accountability, public engagement with democratic processes, and economic growth. This article presents a case study based on one of the data sets created under the federal government's open data program, an XML version of the United States Government Manual published by the Office of the Federal Register. Working with the Government Manual data set uncovered various quality issues that presented technical barriers to data reuse, despite its compliance with open data principles of formatting and licensing. This experience raises questions about the purported link between open data and its promised benefits, which I discuss within the wider context of critiques of open data. 相似文献

The part-time librarian at Penn Presbyterian Medical Center (PPMC) serves physicians, staff, and students. Challenged by time constraints and the need for a physical presence in the library, the librarian sought methods requiring limited manpower and maintenance to reach out to users. The librarian utilized two Web 2.0 technologies, Delicious and Bloglines, to extend library services beyond the confines of the hospital intranet. This article details the process to implement these two technologies in the hospital setting. Informational resources about Web 2.0 technologies are included in the article. 相似文献

When the National Academies Press announced that more than 4,000 electronic books would be made freely available for download, many academic libraries expressed interest in obtaining MARC (Machine Readable Cataloging) records for them. Using cataloging e-mail distribution lists, volunteers were recruited for a project to identify and upgrade bibliographic records for aggregation into a batch that could be easily loaded into catalogs. Project organization, documentation, quality control measures, and problems are described, as well as processes for adding new titles. The project's implications for future efforts are assessed, as are the numerous challenges for network-level cataloging. 相似文献
