Abstract

Few African scholars publish articles in top journals, present papers at prestigious conferences, or produce monographs that influence the direction of the field of communication as a whole. We explored hindrances to scholarly productivity in East Africa by administering questionnaires to faculty members at five leading communication departments and conducting in-depth interviews with department heads, librarians, and other senior faculty members. Results indicated that an increase in institutional priority on research and publication makes this an opportune juncture for collaboration with the international scholarly community to facilitate research and publication activity by African academics.  相似文献

Research about African communication and studies by African-affiliated authors remain scarce in the field of communication. To establish a comprehensive picture of the state of scholarship, 5,228 articles published in 18 top communication journals between 2004 and 2010 were reviewed. Articles were coded for topic nation, author affiliation, article type, category of communication studied, and research method. Thirty-nine Africa-focused articles including 25 authored by researchers from African institutions were found. Over half addressed health communication; most focused on Kenya and South Africa. Means are suggested by which the international scholarly community can partner to encourage African scholarship.  相似文献

Abstract

Neoliberal ideologies, implicated in increasing global inequality, have significantly influenced how global health interventions are conceived and executed. In this article, we take a critical stance towards the market-based impetus of neoliberalism as articulated in the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), the largest comprehensive effort against the global HIV/AIDS epidemic. Using a variety of PEPFAR policy documents, our analysis points to the operation of a neoliberal “common sense” that provides a justification for intervention. Our analysis resulted in three themes: (a) the body as labor, (b) the gendering of the intervention, and (c) political economies of partnerships.  相似文献

Communication and information processes are vital in any company. The use of lean manufacturing concepts applied to the communication and information process aims to reduce waste and make the flows leaner and simpler. Lean information is a new strand of lean concepts and applications. The purpose of this study was to analyze quantitatively the publications concerning the subject, outlining an overview for the new research field of lean communication. Aiming for a deeper understanding, the concepts of lean information were applied in a real process. The quantitative analysis was carried out to find the main authors and works, as well as the main terms used in related works. We used the methods of citations works, co-citation references, and co-occurrence of words using the VOSviewer software. This software was primarily designed to analyze bibliometric networks in order to create, visualize, and assess maps based on network data generated from queries in journals. We found a lack of a methodology for the development and implementation of lean information concepts. We observed a gap which had not been addressed yet, that is, mapping communication flows and developing and implementing lean information. Moreover, there was no method for improvement, implementation, and control.  相似文献

The diffusion of knowledge within organizations provides opportunities for interpersonal co-operation, improves creative ability and therefore leads to competitive advantage. Focus of prior literature on knowledge diffusion has been on identifying factors that influence individuals' behavioral intentions to seek and share knowledge. However, knowledge diffusion as an enigmatic, emergent and organizational-level process is more than the simple aggregation of individual attributes and needs to be further investigated. Accordingly, this study focuses on three distinct system-level factors, i.e., architectures of connections among individuals, distributions of knowledge roles and designs of selection mechanisms and analyses their effects on knowledge diffusion. To be more specific, we examine three distinct knowledge roles: seekers, contributors and brokers. We also distinguish between three types of selection mechanisms: objective selection mechanisms, feedback-based selection mechanisms and random selection mechanisms. By conducting agent-based simulations on four representative networks, i.e., regular networks, random networks, small-world networks and scale-free networks, our results show that the optimal knowledge diffusion performance can be achieved on scale-free networks where all agents implement objective mechanisms and show characteristics of brokers. Moreover, our results (a) highlight the significance of brokers, (b) illustrate the superiority of objective selection rules and (c) demonstrate that scale-free networks provide an optimal framework for knowledge diffusion. Furthermore, we also find the interdependent relevance of these three factors to knowledge diffusion and propose a qualitative explanation of these findings.  相似文献

Colleges and universities in the United States often promote diversity through a neoliberal lens by framing diversity as a celebration of individual differences or a commodity that students can gain by attending their institution. In communication courses, diversity has been conceptualized through both neoliberal and critical lenses, but limited research has investigated how communication students define and explain diversity. The focus of this study was to understand how communication students define diversity. We performed thematic analyses on open-ended survey responses to investigate how communication students define diversity. Four themes emerged from our analyses: (a) diversity is a mechanism for unifying communities, (b) diversity is an affirmation of individual differences, (c) diversity is a harbinger of acceptance and equality, and (d) diversity is a disruptive force that re-centers the voices of traditionally marginalized people. Our findings indicate most communication students define diversity through a neoliberal lens. However, 3% of our participants conceptualized diversity through a critical lens by explaining that diversity should create space for those who are marginalized to have their voices heard. We conclude by providing recommendations for communication instructors to incorporate more critical conversations about diversity into their classrooms and foster diverging discourses about diversity across communication curricula.  相似文献

Using Communication Privacy Management (CPM), this study analyzed Emergency Healthcare Providers (EHP; i.e., Emergency Room Nurses, Paramedics, Emergency Medical Technicians, etc.) frequent experience of witnessing death, the dying processes, and regular involvement at the end-of-life. Twenty interviews from across the United States offered accounts of witnessing the death of a patient, communicating with the patient’s families, coworkers, and personal networks. The first research question explored the population’s normalization of death and changed outlook of dying. This population sees death and dying in real-time and must disconnect at the moment from their emotions to do their jobs. The second research question focused on preparing patient families for death, coping with coworkers, and protecting personal networks. In communicating with patient families, EHP educates/answers questions, advocate for families to be present during life-saving procedures and offer verbal and nonverbal comfort. In talking with coworkers, EHP copes with reassuring skill competency and offering emotional social support. Lastly, in communicating with their networks, EHP struggle with discussing emotions and event details in a protective function. From these results, the benefits, and challenges of communicating about death regularly are offered through a CPM lens, and recommendations to help the general population deal with death are given.  相似文献

To date the development of technical systems to support learning either in schools and universities (CSCL-systems), or in companies (knowledge-management systems) have largely developed separately concurrent, with no or little mutual exchange of experience. The approach presented here seeks to combine the strengths of both lines of development in order that both benefits from each others advantages achieve advantages for each development. Detailed requirements engineering is presented regarding, three research fields: communication theory; learning processes; and a study in companies. The requirements collected led to a sophisticated concept of annotations where annotations serve as communicative contributions, and (segmented) material is used as context. The combination and distinction between communicative contributions, and the material itself is a suitable approach for integrating the advantages of CSCL-systems (communication support) and knowledge management systems (support of content storage). These requirements are combined in a software system, KOLUMBUS, presented with its key features. To gather experience with KOLUMBUS and to convey potential for further improvement, two case studies were conducted. The main results, advantages and further potentials derived from these two case studies are described in this paper. The paper concludes with design recommendations for similar technical systems, as well as organizational hints for CSCL-groups (in schools or universities as well as in companies).  相似文献

This study examines how Muslim women use Internet-based media in the process of acculturation in the United States. Grounded theory methodology (Glaser, 1992) and Sam and Berry’s (2006) model of acculturation were used as theoretical and analytical frameworks. Semi-structured interviews were conducted with 14 Muslim women to learn about their media use and experiences in forming and maintaining relationships in the United States. Educational opportunities were an emerging theme in the determining factors of immigrating to the United States. The data indicated that Muslim women use a variety of Internet-based media such as Facebook, Skype, WhatsApp, Instagram, and Viber for communicating with family and friends locally and abroad. A majority of the participants reported that social media allowed them to express a part of their identities. The data suggests that the participants attained the level of acculturation defined as integration. The participants use these media to build and create relationships in their new communities. The combined relationships the participants maintain both locally and abroad seem to play a role in the creation of balance in their lives, which allows them to thrive in their new communities, at school, and at work.  相似文献
