EBSCO's Communication & Mass Media Complete: An Appreciable Improvement Over Previous Communication Studies Indexing?

ABSTRACT

In a prior edition of this study, we examined whether the established online communication studies indexes—Communication Abstracts, ComIndex, and ComAbstracts—provided a good avenue of access to the journal literature that researchers in the field cite and whether, where the current journal literature was concerned, that avenue of access might be equal or superior to that provided by large, multisubject online indexes. In this iteration of the study, we similarly address EBSCO's new product for communication studies, Communication & Mass Media Complete.     

The relationships of online journalists' emotional responses to competitors with job satisfaction,workload, and perception of the quality of the news website

An e-mail survey of online journalists reveals that online journalists' emotional responses to their competitors' coverage are significantly correlated with their job satisfaction, workload, and the perceived quality of their news website. The more negatively online journalists feel when they get scooped by their competitors, the more unsatisfied they are with their jobs. The more negatively the journalists feel about getting scooped, the more the workload the journalists feel that they have. The more positively online journalists feel when they scoop their competitors, the more positively they perceive the quality of their news website. In addition, the greater the workload the journalists consider that they have, the more unsatisfied they are with their jobs. The more positively the journalists perceive the quality of their news organization, the more satisfied they are with their jobs.     

Picturing terrorism through Arabic lenses: a comparative analysis of Al Jazeera and Al Arabiya

This study examines the coverage of terrorism in two leading Arab news websites, Al Jazeera and Al Arabiya from 11 September 2009 to 10 September 2010. It finds that the stereotype that ‘the terrorist is a Muslim’ continues in terrorism coverage, despite the fact that some terrorists are non-Muslims. However, the two sites manage to send out the message that ‘the majority of terrorism victims are Muslims.’ In addition, the findings reveal that too much media focus is placed on disseminating and supporting official positions and decisions, and humanitarian sufferings from terrorism are seldom brought to the attention of the public.     

THE CONTINGENCIES OF ORDINARY CITIZEN APPEARANCES IN POLITICAL TELEVISION NEWS

While few would deny the crucial role of citizens in democratic governance, there are still only a few studies that focus on ordinary citizens’ inclusion in political news coverage. First, we present a number of factors conditioning ordinary citizens’ appearances in the news. Second, based on the discussion of these factors, we formulate a number of research questions. After conducting an extensive content analysis covering almost 6000 actors appearing in political news coverage in the two major Danish broadcasters, DR1 and TV2, between 1994 and 2007, we find that ordinary citizens appear more often in reports on intrusive issues such as welfare, that they appear more often in news items positioned later in the news bulletins, that they, largely speaking, appear more often closer to election day, but that there are almost no differences between commercial and public service broadcasting. These findings are discussed in the light of past research on media source use and the ongoing changing foundations of political communication.     

News Coverage of U.S. Mothers of Soldiers During the Vietnam War

The press of World Wars I and II depicted patriotic mothers as Spartan-like in their support of the nation's war effort. During the Vietnam War, another maternal image emerged to share cultural space with the Spartan mother, that of the goddess Thetis who objected to her son's participation in the Trojan War. This alternative maternal symbol more closely resembles the archetypal image of the peacetime good mother, who cares for her children and resists sending them into harm's way. This study documents coverage of maternal opposition to the Vietnam War against the backdrop of coverage of US mothers of soldiers in the earlier world wars. The comparison suggests that the Great Father's failure to control the press and promote the war to US citizens provided an opportunity for Thetis' rising.     

The Alternative Platform: Kenya’s Television Stations Navigation During the Switch Off of Raila Odinga’s “Swearing-In”

ABSTRACT

The role of communication technologies in Kenyan newsrooms particularly from print media perspective has been investigated. However, how these technologies aid television journalism practice in Kenyan context is understudied. Using the government ban of selected television stations in Kenya during and after the symbolic “swearing-in” of opposition presidential candidate in the 2017 general election, this study investigated the influence of communication technologies by the affected television stations to circumvent government crackdown. Interview was used as the primary method for data collection. The findings of the study revealed that throughout the switch off period the newsrooms remained operational but forced to develop alternative strategies fundamentally buoyed by new media technologies to disseminate contents. Though the strategies produced unintended and unexpected effects as the findings indicated. The main challenge with technology, was news verification, since the stations were using guerrilla tactics to source news which was not easily forthcoming. In addition, there was economic implication, some advertisers demanded for a refund and potential advertisers refused to patronise the stations which according to one of the editors was hinged on fear of being targeted by government.     

A progressive sentence selection strategy for document summarization

Saliency and coverage are two of the most important issues in document summarization. In most summarization methods, the saliency issue is usually of top priority. Many studies are conducted to develop better sentence ranking methods to identify the salient sentences for summarization. It is also well acknowledged that sentence selection strategies are very important, which mainly aim at reducing the redundancy among the selected sentences to enable them to cover more concepts. In this paper, we propose a novel sentence selection strategy that follows a progressive way to select the summary sentences. We intend to ensure the coverage of the summary first by an intuitive idea, i.e., considering the uncovered concepts only when measuring the saliency of the sentences. Moreover, we consider the subsuming relationship between sentences to define a conditional saliency measure of the sentences instead of the general saliency measures used in most existing methods. Based on these ideas, a progressive sentence selection strategy is developed to discover the “novel and salient” sentences. Compared with traditional methods, the saliency and coverage issues are more integrated in the proposed method. Experimental studies conducted on the DUC data sets demonstrate the advantages of the progressive sentence selection strategy.     

The theatricality of sport and the issue of ideology

Through the study of Richard Gruneau and Gunter Gebauer’s respective works, this article examines the social significance and theoretical implications of sport’s capacity to represent social life in a theatrical manner. The drama-like images and representations sporting practices produce, institutions codify, and television programs enhance is considered in relation to ideology’s integrative, legitimating, and distorting functions (Ricoeur). Acknowledging the filiations of ‘theatre’ with ‘theory’ – both words stand for ‘to contemplate, to see, to observe’ – this study considers theatricality as a valuable theoretical notion that enables a synthetic and reflexive understanding of athletic practices’ bodily dimension, symbolic representations, and institutional determinants.
