Social media's impact on journalism : a study of media's coverage of anti-corruption protests in India

The year 2011 was memorable for many in India – for those who participated in numerous anti-corruption protests, and for those who witnessed these protests via all pervasive mainstream news media. This paper will use inter-media agenda-setting discourse to explain the Indian media’s coverage of the so-called ‘Anna movement’. It will outline how the use of mobile and social media platforms by the ‘India Against Corruption’ organisers and the educated middle class influenced the mainstream media’s coverage of the protests. The paper will consider the implication of this coverage, in the light of the unique position of power the Indian news media has in this transitioning society.

The rhetoric of ‘community’ : ABC local radio's coverage of the 2009 Victorian bushfires

This article joins recent debates in media and communication studies concerning audience participation in news journalism. Specifically, we investigate the impact of an increasing reliance on audience-generated content on newsroom practice in traditional media organisations. We do this by recounting and analysing the experiences of journalists involved in ABC Radio's coverage of the dramatic Victorian bushfires of early 2009, which relied heavily in listener contributions and was closely integrated with the ABC's online coverage. Interviews with two staff at ABC Gippsland, and the ABC's Manager of Emergency Broadcasting provide the basis for a case study of the kinds of tensions that media workers routinely confront within an organisation like the ABC. The interviews suggest that in negotiating the possibility of increased audience participation, journalists and their managers are thinking about much more that the rhetorics of democracy and the validity of news values: their focus is also on a complex structure, the need for skill (re)development and the precise mechanics of creating and maintaining productive relationships with local communities. The significance of the research lies in its attempt to bring together a number of related factors: the increasingly active role of audiences in generating and supplying news content; the impact of digital communications technologies on news production practices; and the ABC's ongoing development of its now contested role as an 'emergency broadcaster'.

The Victorian bushfires and extreme weather events : media coverage, crisis and communication

The 2009 'Black Saturday' Victorian bushfires claimed the lives of 173 people and have become known as the worst fire event in Australian history. Victoria has been at the centre of two other significant Australian fire disasters - 'Black Friday' in 1939 and the 1983 'Ash Wednesday' fires in south-eastern Australia that claimed the lives of 47 people in Victoria. As media scholar and commentator Michael Gawenda has noted, the media not only report an 'event' - like the Victorian bushfires or the tsunami in the South Pacific - but in a sense create and define it. Print and electronic media coverage of extreme weather events therefore raises a multitude of issues about the media's role in serving the community before, during and after a crisis, while also trying to produce the best possible reportage in a competitive industry undergoing dramatic change. This issue of MIA provides a venue for critical, empirical engagement with media coverage and representation, and the role of journalism and journalists in reporting national and international bushfires, tsunamis, hurricanes and other extreme weather events, with a special focus on the 2009 Victorian bushfires. Its goal is to address the ramifications of an industry in flux - indeed, some may say crisis - driven by technological advances, staff reductions and media organisations under financial pressure, and to explore the ways in which such extreme weather events have impacted media practices and policy

Race, genetic determinism and the media: an exploratory study of media coverage of genetics and Indigenous Australians

Social scientists and Indigenous people have voiced concerns that media messages about genetics and race may increase the public's belief in genetic determinism and even increase levels of racism. The degree of genetic determinism in media messages has been examined as a determining factor. This study is the first to consider the implications of this area of scholarship for the indigenous minority in Australia. A search of the last two decades of major Australian newspapers was undertaken for articles that discussed Indigenous Australians and genetics. The review found 212 articles, of which 58 concerned traits or conditions that were presented in a genetically deterministic or antideterministic fashion. These 58 articles were analysed by topic, slant, and time period. Overall, 23 articles were anti-deterministic, 18 were deterministic, 14 presented both sides and three were ambiguous. There was a spike in anti-deterministic articles in the years after the Human Genome Diversity Project, and a parallel increase in deterministic articles since the completion of the Human Genome Project in 2000. Potential implications of the nature of media coverage of genetics for Indigenous Australians is discussed. Further research is required to test directly the impact of these messages on Australians.

How Relevant is the ‘Terror Frame’ for Discussing Media Coverage of Iraq in 2013? A Preliminary Study

This paper is a preliminary study of the terror frame as it is applied to media coverage of Iraq 10 years after the 2003 American-led intervention that toppled Saddam Hussein.

Can analyst coverage reduce the incidence of fraud? Evidence from China

We investigate the impact of security analyst coverage on the incidence of corporate financial fraud in China. After controlling for the endogeneity between analyst following and fraud, we find that financial analyst coverage cannot significantly influence the incidence of fraud. The empirical findings suggest that financial analysts do not serve as external monitors to managers and large shareholders in China. © 2014 Taylor & Francis.

General approach for electrochemical functionalization of glassy carbon surface by in situ generation of diazonium ion under acidic and non-acidic condition with a cascade protocol

Immobilization of catechol derivatives on GC electrode surfaces can be performed by in situ generation and reduction of nitrocatechol. We present the oxidative nitration of catechol in the presence of nitrous acid followed by electrochemically reduction of the generated nitro aromatic group to the corresponding amine group and its conversion to diazonium cation at the electrode surface to yield a surface covalently modified with catechol. In this manner, some derivatives of catechol can be immobilized on the electrode surface. Whole of the process is carried out in Triethylammonium acetate ionic liquid as an inert and neutral medium (pH∼7.0). Surface coverage can be easily controlled by the applied potential, time and concentration of catechol. After modification, the electrochemical features of modified surface have been studied. Also modified GC electrode exhibited remarkable catalytic activity in the oxidation of NADH. The catalytic currents were proportional to the concentration of NADH over the range 0.01-0.80 mM. This condition can be used for modification of GC surfaces by various aromatic molecules for different application such as design of sensors and biosensors. © 2014 Elsevier Ltd. All rights reserved.

The propaganda strategies adopted by the Colonial British during the Malayan Emergency, 1948-1960 as applied in newspaper coverage: A case study

The ongoing discussions on the fluid boundaries between ‘propaganda’ and ‘persuasion’ have emerged in numerous studies, the most prominent being Jowett and O’Donnell (2006). Sharing their views, Herman and Chomsky (1988) argued on the repercussions of only using elite sources in media reports due to their capacity to mobilise the masses for a single cause and shape elite opinions, due to the absence of alternative or opposing viewpoints. This case study examined the nature of propaganda strategies adopted by the colonial British during the Malayan Emergency that proved to be highly effective. This study consisted of two separate elements. First, it extends the discussion on propaganda by examining the significance of ‘race’ used as a crucial element within the discourses of anti-communism, as a legitimate rationale to mobilise forces, primarily within a Malayan context. Second, it investigated how propaganda strategies such as the forced resettlement of the ethnic Chinese, strategies used in framing the insurgents, and psychological warfare operated as powerful mechanisms to shape propaganda communication. A comparative content analysis of two mainstream English newspapers – namely The Times (London) and Straits Times (Singapore) – was conducted to identify trends in reporting used. Juxtaposing this method was the administration of in-depth interviews with ex-service personnel who had actively served in Malaya during the Malayan Emergency. The findings of this research reveal a significant correlation between ‘race’ and the constructs of communism. The results also indicate that psychological strategies adopted by the British in the form of deeds and news production proved to be highly effective.

Structure of arginine overlayers at the aqueous gold interface: implications for nanoparticle assembly.

Adsorption of small biomolecules onto the surface of nanoparticles offers a novel route to generation of nanoparticle assemblies with predictable architectures. Previously, ligand-exchange experiments on citrate-capped gold nanoparticles with the amino acid arginine were reported to support linear nanoparticle assemblies. Here, we use a combination of atomistic modeling with experimental characterization to explore aspects of the assembly hypothesis for these systems. Using molecular simulation, we probe the structural and energetic characteristics of arginine overlayers on the Au(111) surface under aqueous conditions at both low- and high-coverage regimes. In the low-density regime, the arginines lie flat on the surface. At constant composition, these overlayers are found to be lower in energy than the densely packed films, although the latter case appears kinetically stable when arginine is adsorbed via the zwitterion group, exposing the charged guanidinium group to the solvent. Our findings suggest that zwitterion-zwitterion hydrogen bonding at the gold surface and minimization of the electrostatic repulsion between adjacent guanidinium groups play key roles in determining arginine overlayer stability at the aqueous gold interface. Ligand-exchange experiments of citrate-capped gold nanoparticles with arginine derivatives agmatine and N-methyl-l-arginine reveal that modification at the guanidinium group significantly diminishes the propensity for linear assembly of the nanoparticles.

Target coverage in camera networks for manufacturing workplaces

In this paper, we investigate the camera network placement problem for target coverage in manufacturing workplaces. The problem is formulated to find the minimum number of cameras of different types and their best configurations to maximise the coverage of the monitored workplace such that the given set of target points of interest are each k-covered with a predefined minimum spatial resolution. Since the problem is NP-complete, and even NP-hard to approximate, a novel method based on Simulated Annealing is presented to solve the optimisation problem. A new neighbourhood generation function is proposed to handle the discrete nature of the problem. The visual coverage is modelled using realistic and coherent assumptions of camera intrinsic and extrinsic parameters making it suitable for many real world camera based applications. Task-specific quality of coverage measure is proposed to assist selecting the best among the set of camera network placements with equal coverage. A 3D CAD of the monitored space is used to examine physical occlusions of target points. The results show the accuracy, efficiency and scalability of the presented solution method; which can be applied effectively in the design of practical camera networks.
