Abstract

This chapter presents an overview of the Brazilian regional media groups that are characterized by cross-ownership of media outlets in the four main reference platforms for news coverage: daily print, radio, broadcast television, and Web.

The research uses institutional documents to explore the history and operating mode of the groups that own the 50 best-selling newspapers in the country. The theoretical approach is guided by the notion of “spatialization” applied to business communication by Vincent Mosco, and by the concepts of “region,” “regionality,” and “regionalization” based upon authors aligned with the critical thinking approach in the field of geography.

The study identifies the multiple geographical scales at which these groups operate, as well as their dominant business models and the sources of their owners’ capital. Based on this analysis, it argues that the variables which are applied to the large-circulation media at a national level cannot be automatically transferred to the regional and local levels.

The study of regional media reveals a landscape that has not received adequate attention from communications researchers worldwide. It also points to problems which deserve more investigation and elaboration. This represents a new challenge for media studies, for the political economy of communication, and for the nascent field of geography of communication.

This chapter provides a distinctive and nuanced approach to the Brazilian media system. It can inspire other studies on regional communication which take into account the specificities of their geographic scales.

Abstract

How do European policymakers and media companies react to the AOL‐TimeWarner merger? In this short provocation, Marsden asks whether the successful coupling of the world’s largest ISP and media content creator signal le defi americain in communications, for Europe and the rest of the world? In particular, he questions whether market actors should be permitted a similar role in Europe. In competition policy terms, the question is whether creation of economies of scale and scope, particularly through vertical integration between carriers and content providers, now causes increasing redundancy of media‐specific ownership laws at a national level in favour of European industrial policy? The outflanking policy trend is demonstrated specifically in the merger of Vodafone‐Mannesmann, and the content alliances formed with Vivendi, and between Vodafone, Vivendi and variously BSkyB and Manchester United. Even if symbolic debate continues to give primacy to democratic principle, European public policy may switch poles, from denying concentration of media on democratic principle of pluralism of ownership, to encouraging European champions to compete with the Americans. This convergence debate will centrally occupy policymakers, with new national legislation and Commission Directives in all probability preceded by critical merger decisions by the Competition Directorate.

Abstract

Purpose

An indirect electrochemical reduction and dyeing with indigo were carried out here to solve problems of low dye reduction rate and poor dyeing depth in the current electrochemical dyeing process.

Design/methodology/approach

Response surface analysis tests were performed to evaluate the effects of ferrous sulfate concentration, medium concentration, sodium hydroxide concentration and reduction time on the reduction efficiency of indirect electrochemical reduction of indigo.

Findings

The conditions obtained by design-expert optimization showed that the concentration of FeSO4·7H2O has the most significant effect on the reduction performance of dye liquor. Under the optimized electrochemical reduction dyeing process, the rate of dye reduction could be reached 91.21 per cent and the K/S value of indirect electrochemical dyeing of indigo can be achieved to 12.96, which is increased by about 9.56 per cent compared with that of Na2S2O4 dyeing with the same color fastness basically.

Research limitations/implications

The recyclability and biodegradability of the dye remain to be explored.

Practical implications

The strategy presented here can be developed to replace a substantial part of electrochemical dyeing with optimized product quality and reduced environmental pollution in denim production.

Social implications

The strategy presented here can be developed to replace a substantial part of electrochemical dyeing with optimized product quality and reduced environmental pollution in denim production.

Originality/value

Application of the Fe(II)-DGS-Abal B complex media system in the indirect electrochemical reduction of indigo.

Abstract

Purpose

The purpose of this paper is to study the effects of chemical reaction on mixed convection flow along a sphere in non‐Darcian porous media.

Design/methodology/approach

The sphere surface is maintained at uniform temperature and species concentration for both cases of heated (assisting flow) and cooled (opposing flow) sphere. An appropriate transformation is employed and the transformed equations are solved numerically using an efficient implicit iterative tri‐diagonal finite difference method.

Findings

It is found that chemical reactions have significant effect on heat and mass transfer. Comparisons with previously published work are performed and the results are found to be in excellent agreement.

Originality/value

The paper is original and describes how a parametric study of the physical parameters was conducted and illustrates graphically a representative set of numerical results for the velocity, temperature, and concentration profiles, as well as the local skin‐friction coefficient, local wall temperature, and local wall concentration, to show interesting features of the solutions.

Abstract

The chapter addresses the unique aspects of Brazil’s news agencies and the Brazilian news syndication market. It reveals the pattern of Brazil’s two prevailing business models regarding the wire services industry: that of the State, particularly the federal government, which invested little in a nationwide distributor to peripheral and alternative media; and that of major media conglomerates, which set out their syndication services labeled as “news agencies” in order to multiply profits with no extra labor. In the latter case, an asymmetrical relationship of dependency and circularity ensues between these major conglomerates and regional media groups, who rely on these “news agencies” to perpetuate their dominance in local markets. The chapter also assesses a few causes for this unique model and describes the main players in Brazil’s news agency sector. A concise historical background is presented (Molina, Morais, Saroldi & Moreira) and provides context for the present-day players in the news agency business in Brazil, including the institutional framework they form with their customers, predominantly smaller newspapers. The chapter analyzes attributes of the Brazilian news agency ecology, including the parallel reach of distribution networks belonging to the private and state-owned agencies; the adaptation of conglomerate agencies to challenges entailed by the digital convergence (shrinking newsrooms, multitasking staff); and the prevalence of the interconglomerate model within the Brazilian news syndication industry.

Abstract

Purpose – It may be time to reformulate the rejection of censorship. Freedom is not the only opposite of, strategic resource against, or antidote to, censorship. Methodology/Approach – This chapter argues against censorship with a Kantian-normative approach (the deontological position of the categorical imperative), using conceptual analysis, constructivism, and international legal scholarship, from the standpoint of a humanity-wide duty to safeguard and promote cultural diversity and biodiversity. Increasingly visible weaknesses of the argument against censorship from the utilitarian standpoint of freedom, a negative argument, can be avoided in this way. Findings – Especially the neoliberal approach to freedom has no provisions against corporate and only little against copyright censorship, which are both becoming increasingly acute. Diversity, on the other hand, both biological and cultural, is argued to be instrumentally good, and intrinsically good, but the latter only if balanced by equality of basic rights. Originality/Value – The resulting moral and legal imperatives are to support, safeguard, and promote diversity, and thus to minimize both censorship in culture and selection/elimination in nature, but only to minimize them, simply because they cannot themselves be eliminated. It is impossible to eliminate elimination. This becomes clear when one considers self- and soft censorship. At least in the wide sense, censorship is inevitable – but sustainable development is impossible without strict minimization of censorship.

Abstract

In this chapter, the authors focus on a range of Australian news articles selected for their relevance to key themes in the area of child abuse and examine two high profile cases of child abuse deaths that were extensively reported on by the media and led to system reform. Challenges for media reporting on child abuse in Australia including a changing media landscape, lack of available child abuse data and lack of publicly available serious case reviews are discussed. The authors argue that there is a need for attention to be paid to children's resistance and agency in the context of violence and abuse to counter the objectification of children and uphold their rights. Following Finkelhor (2008), the authors argue that media reporting on child abuse in Australia reflects a general approach to child abuse that is fragmented, with different types of abuse viewed as separate from one another, and call for a more integrated understanding of child abuse. The authors highlight the complexity of media responses to child abuse in Australia, noting that while the social problem of child abuse can be misrepresented by the media, media reporting has also triggered significant systemic reform and advocated for children in cases where other systems failed them.

Abstract

Purpose

The main goal of this paper is to evaluate the players' contribution and economic value in the soccer industry. Media visibility records provide us with comparable metrics to identify talent and make hiring decisions – these records can jointly capture sport (on-field) skills and other attractive (off-field) abilities.

Design/methodology/approach

This paper presents a valuation method that applies media visibility appraisals to estimate “theoretical values” of the transfer fees paid for hiring soccer players. The estimations are performed by analysing the evolution over time of the media exposure of about 5,000 individuals of more than 200 clubs.

Findings

The study’s empirical results reveal that, along with sport performance, the players' media status also affects their economic valuation, which explains why the clubs – in search of greater economic returns – fiercely compete for the most popular players. The paper also identifies the main factors determining the players' economic value. In predicting the players' transfer fees, some variables are statistically significant: individual media visibility, media visibility share of the player within his team, contract duration, status of the hiring team, years of experience, player's age at the end of the contract and the domestic league of the hiring team.

Originality/value

Professional sports provide reliable measures on individuals' performance that may help in the hiring process of workers. This paper identifies gifted soccer players while taking into account their skills as media leaders and the economic implications. Insofar as players' talents determine their teams' sport and economic achievements, the transfer fees paid for players must then be seen as a crucial factor. Measuring individual talent and being able to translate this talent into productivity levels entail serious methodological and empirical challenges.
