As a key element in their response to new media forcing transformations in mass media and media use, newspapers have deployed various strategies to not only establish online and mobile products, and develop healthy business plans, but to set out to be dominant portals. Their response to change was the subject of an early investigation by one of the present authors (Keshvani 2000). That was part of a set of short studies inquiring into what impact new software applications and digital convergence might have on journalism practice (Tickle and Keshvani 2000), and also looking for demonstrations of the way that innovations, technologies and protocols then under development might produce a “wireless, streamlined electronic news production process (Tickle and Keshvani 2001).” The newspaper study compared the online products of The Age in Melbourne and the Straits Times in Singapore. It provided an audit of the Singapore and Australia Information and Communications Technology (ICT) climate concentrating on the state of development of carrier networks, as a determining factor in the potential strength of the two services with their respective markets. In the outcome, contrary to initial expectations, the early cable roll-out and extensive ‘wiring’ of the city in Singapore had not produced a level of uptake of Internet services as strong as that achieved in Melbourne by more ad hoc and varied strategies. By interpretation, while news websites and online content were at an early stage of development everywhere, and much the same as one another, no determining structural imbalance existed to separate these leading media participants in Australia and South-east Asia. The present research revisits that situation, by again studying the online editions of the two large newspapers in the original study, and one other, The Courier Mail, (recognising the diversification of types of product in this field, by including it as a representative of Newscorp, now a major participant). The inquiry works through the principle of comparison. It is an exercise in qualitative, empirical research that establishes a comparison between the situation in 2000 as described in the earlier work, and the situation in 2014, after a decade of intense development in digital technology affecting the media industries. It is in that sense a follow-up study on the earlier work, although this time giving emphasis to content and style of the actual products as experienced by their users. It compares the online and print editions of each of these three newspapers; then the three mastheads as print and online entities, among themselves; and finally it compares one against the other two, as representing a South-east Asian model and Australian models. This exercise is accompanied by a review of literature on the developments in ICT affecting media production and media organisations, to establish the changed context. The new study of the online editions is conducted as a systematic appraisal of the first level, or principal screens, of the three publications, over the course of six days (10-15.2.14 inclusive). For this, categories for analysis were made, through conducting a preliminary examination of the products over three days in the week before. That process identified significant elements of media production, such as: variegated sourcing of materials; randomness in the presentation of items; differential production values among media platforms considered, whether text, video or stills images; the occasional repurposing and repackaging of top news stories of the day and the presence of standard news values – once again drawn out of the trial ‘bundle’ of journalistic items. Reduced in this way the online artefacts become comparable with the companion print editions from the same days. The categories devised and then used in the appraisal of the online products have been adapted to print, to give the closest match of sets of variables. This device, to study the two sets of publications on like standards -- essentially production values and news values—has enabled the comparisons to be made. This comparing of the online and print editions of each of the three publications was set up as up the first step in the investigation. In recognition of the nature of the artefacts, as ones that carry very diverse information by subject and level of depth, and involve heavy creative investment in the formulation and presentation of the information; the assessment also includes an open section for interpreting and commenting on main points of comparison. This takes the form of a field for text, for the insertion of notes, in the table employed for summarising the features of each product, for each day. When the sets of comparisons as outlined above are noted, the process then becomes interpretative, guided by the notion of change. In the context of changing media technology and publication processes, what substantive alterations have taken place, in the overall effort of news organisations in the print and online fields since 2001; and in their print and online products separately? Have they diverged or continued along similar lines? The remaining task is to begin to make inferences from that. Will the examination of findings enforce the proposition that a review of the earlier study, and a forensic review of new models, does provide evidence of the character and content of change --especially change in journalistic products and practice? Will it permit an authoritative description on of the essentials of such change in products and practice? Will it permit generalisation, and provide a reliable base for discussion of the implications of change, and future prospects? Preliminary observations suggest a more dynamic and diversified product has been developed in Singapore, well themed, obviously sustained by public commitment and habituation to diversified online and mobile media services. The Australian products suggest a concentrated corporate and journalistic effort and deployment of resources, with a strong market focus, but less settled and ordered, and showing signs of limitations imposed by the delay in establishing a uniform, large broadband network. The scope of the study is limited. It is intended to test, and take advantage of the original study as evidentiary material from the early days of newspaper companies’ experimentation with online formats. Both are small studies. The key opportunity for discovery lies in the ‘time capsule’ factor; the availability of well-gathered and processed information on major newspaper company production, at the threshold of a transformational decade of change in their industry. The comparison stands to identify key changes. It should also be useful as a reference for further inquiries of the same kind that might be made, and for monitoring of the situation in regard to newspaper portals on line, into the future.

Tensions surrounding social media in the employment relationship are increasingly evident in the media, public rhetoric, and courts and employment tribunals. Yet the underlying causes and dimensions of these tensions have remained largely unexplored. This article firstly reviews the available literature addressing social media and employment, outlining three primary sources of contestation: profiling, disparaging posts and blogs, and private use of social media during work time. In each area, the key dynamics and underlying concerns of the central actors involved are identified. The article then seeks to canvas explanations for these forms of contestation associated with social media at work. It is argued that the architecture of social media disrupts traditional relations in organisational life by driving employer and employee actions that (re)shape and (re)constitute the boundaries between public and private spheres. Although employers and employees are using the same social technologies, their respective concerns about and points of entry to these technologies, in contrast to traditional manifestations of conflict and resistance, are asymmetric. The article concludes with a representational summary of the relative legitimacy of concerns for organisational actors and outlines areas for future research.

This paper aims to provide a contextualised and embedded exploration of how the notions of "practice" and "participation", key concepts in the study of culture and media, are manifest in an example of a complex creative project. This project aimed to engage with refugees and asylum seekers through the co-creation of cultural material and is an outcome of an? ethnographic action research (Tacchi et al. 2003) partnership involving a community development worker in a settlement support agency and a storytelling/community media researcher (the author), along with other project collaborators. The discussion of this project focuses on the role of the facilitator and illustrates the processes of orchestrating a complex project involving a series of linked stages with cumulative effect. As practitioners at this site we are working in the space where personal narratives, participatory arts and media, and the staging of intercultural, civic dialogue events, intersect. Co-creative media facilitation in these contexts involves both managing hybrid communicative spaces and (re)combining the "integrative practices" (Schatzki 1996) of a range of professional approaches and creative roles. This is liminal work, located on the boundaries of several disciplines and practices. Drawing on reflections gathered from collaborative ethnographic descriptions (Bhattacharya 2008), this paper traces moments of practitioner uncertainty that can be linked to the way "practice" and “participation” is problematised within the community cultural development field in a way that is at times an uneasy fit with conventional ways of operating in social service roles. These moments of tension also indicate where this project pushed practitioners into spaces of improvisation and new learning. Keywords: Youth, refugees, community cultural development, co-creative media facilitation, ethnographic action research, intercultural dialogue.

A significant media city globally , Sydney is the production and design centre for the Australian media system and a subsidiary node of larger international systems principally headquartered in Los Angeles and London. Its media cluster is undergoing transformations to improve its position internationally by increasing capabilities and ties to other Australian and international production clusters. Sydney’s media cluster is a collection of suburbs forming an “arc” along major transport corridors stretching from Macquarie Park in the north to Sydney airport in the south. As a dispersed rather than tightly bound cluster, it is defined by the functional proximity provided by automobile and telecommunication networks Sydney’s media cluster is considered here along two dimensions—that of Sydney’s place within the ecology of Australian and international media and that of its internal organization within the geographical space of metropolitan Sydney. The first examines Sydney’s media cluster at the level of the metropolitan area of Sydney within its state, national and international contexts; while the second digs below this level to explore its working out in urban space.

This chapter examines patterns in social media activity around Australian elections, focusing primarily on the 2013 federal election and supplemented by extended research into social media and Australian politics between 2007 and 2015. The coverage of Australian elections on social media is analysed from three perspectives: the evolution of the use of online platforms during elections; politician and party social media strategies during the 2013 election, focusing on Twitter; and citizen engagement with elections as demonstrated through election day tweeting practices. The specific context of Australian politics, where voting is compulsory, and the popularity of social media platforms like Twitter makes this case notably different from other Western democracies. It also demonstrates the extended mediation of politics through social media, for politicians and citizens alike.

There is a widely held view that the nation-state has become less central to media and communications policy over the last two decades. As Jan van Cuilenberg and Denis McQuail (2003, p. 181) observed in their overview of trends in communications policy-making, 'the old normative media policies have been challenged and policy-makers are searching for a new communications policy paradigm'. There are characteristically five factors put forward as to why the nation-state has become less central to media in the twenty-first century

Communication and Political Crisis explores the role of the global media in a period of intensifying geopolitical conflict. Through case studies drawn from domestic and international political crises such as the conflicts in the Middle East and Ukraine, leading media scholar Brian McNair argues that the digitized, globalized public sphere now confronted by all political actors has produced new opportunities for social progress and democratic reform, as well as new channels for state propaganda and terrorist spectaculars such as those performed by the Islamic State and Al Qaeda. In this major work, McNair argues that the role of digital communication will be crucial in determining the outcome of pressing global issues such as the future of feminism and gay rights, freedom of speech and media, and democracy itself.

This study examines different ways in which the concept of media pluralism has been theorized and used in contemporary media policy debates. Access to a broad range of different political views and cultural expressions is often regarded as a self-evident value in both theoretical and political debates on media and democracy. Opinions on the meaning and nature of media pluralism as a theoretical, political or empirical concept, however, are many, and it can easily be adjusted to different political purposes. The study aims to analyse the ambiguities surrounding the concept of media pluralism in two ways: by deconstructing its normative roots from the perspective of democratic theory, and by examining its different uses, definitions and underlying rationalities in current European media policy debates. The first part of the study examines the values and assumptions behind the notion of media pluralism in the context of different theories of democracy and the public sphere. The second part then analyses and assesses the deployment of the concept in contemporary European policy debates on media ownership and public service media. Finally, the study critically evaluates various attempts to create empirical indicators for measuring media pluralism and discusses their normative implications and underlying rationalities. The analysis of contemporary policy debates indicates that the notion of media pluralism has been too readily reduced to an empty catchphrase or conflated with consumer choice and market competition. In this narrow technocratic logic, pluralism is often unreflectively associated with quantitative data in a way that leaves unexamined key questions about social and political values, democracy, and citizenship. The basic argument advanced in the study is that media pluralism needs to be rescued from its depoliticized uses and re-imagined more broadly as a normative value that refers to the distribution of communicative power in the public sphere. Instead of something that could simply be measured through the number of media outlets available, the study argues that media pluralism should be understood in terms of its ability to challenge inequalities in communicative power and create a more democratic public sphere.

Finland witnessed a surge in crime news reporting during the 1990s. At the same time, there was a significant rise in the levels of fear of crime reported by surveys. This research examines whether and how the two phenomena: news media and fear of violence were associated with each other. The dissertation consists of five sub-studies and a summary article. The first sub-study is a review of crime reporting trends in Finland, in which I have reviewed prior research and used existing Finnish datasets on media contents and crime news media exposure. The second study examines the association between crime media consumption and fear of crime when personal and vicarious victimization experiences have been held constant. Apart from analyzing the impact of crime news consumption on fear, media effects on general social trust are analyzed in the third sub-study. In the fourth sub-study I have analyzed the contents of the Finnish Poliisi-TV programme and compared the consistency of the picture of violent crime between official data sources and the programme. In the fifth and final sub-study, the victim narratives of Poliisi-TV s violence news contents have been analyzed. The research provides a series of results which are unprecedented in Finland. First, it observes that as in many other countries, the quantity of crime news supply has increased quite markedly in Finland. Second, it verifies that exposure to crime news is related to being worried about violent victimization and avoidance behaviour. Third, it documents that exposure to TV crime reality-programming is associated with reduced social trust among Finnish adolescents. Fourth, the analysis of Poliisi-TV shows that it transmits a distorted view of crime when contrasted with primary data sources on crime, but that this distortion is not as big as could be expected from international research findings and epochal theories of sociology. Fifth, the portrayals of violence victims in Poliisi-TV do not fit the traditional ideal types of victims that are usually seen to dominate crime media. The fact that the victims of violence in Poliisi-TV are ordinary people represents a wider development of the changing significance of the crime victim in Finland. The research concludes that although the media most likely did have an effect on the rising public fears in the 1990s, the mechanism was not as straight forward as has often been claimed. It is likely that there are other factors in the fear-media equation that are affecting both fear levels and crime reporting and that these factors are interactive in nature. Finally, the research calls for a re-orientation of media criminology and suggests more emphasis on the positive implications of crime in the media. Keywords: crime, media, fear of crime, violence, victimization, news

Light scattering, or scattering and absorption of electromagnetic waves, is an important tool in all remote-sensing observations. In astronomy, the light scattered or absorbed by a distant object can be the only source of information. In Solar-system studies, the light-scattering methods are employed when interpreting observations of atmosphereless bodies such as asteroids, atmospheres of planets, and cometary or interplanetary dust. Our Earth is constantly monitored from artificial satellites at different wavelengths. With remote sensing of Earth the light-scattering methods are not the only source of information: there is always the possibility to make in situ measurements. The satellite-based remote sensing is, however, superior in the sense of speed and coverage if only the scattered signal can be reliably interpreted. The optical properties of many industrial products play a key role in their quality. Especially for products such as paint and paper, the ability to obscure the background and to reflect light is of utmost importance. High-grade papers are evaluated based on their brightness, opacity, color, and gloss. In product development, there is a need for computer-based simulation methods that could predict the optical properties and, therefore, could be used in optimizing the quality while reducing the material costs. With paper, for instance, pilot experiments with an actual paper machine can be very time- and resource-consuming. The light-scattering methods presented in this thesis solve rigorously the interaction of light and material with wavelength-scale structures. These methods are computationally demanding, thus the speed and accuracy of the methods play a key role. Different implementations of the discrete-dipole approximation are compared in the thesis and the results provide practical guidelines in choosing a suitable code. In addition, a novel method is presented for the numerical computations of orientation-averaged light-scattering properties of a particle, and the method is compared against existing techniques. Simulation of light scattering for various targets and the possible problems arising from the finite size of the model target are discussed in the thesis. Scattering by single particles and small clusters is considered, as well as scattering in particulate media, and scattering in continuous media with porosity or surface roughness. Various techniques for modeling the scattering media are presented and the results are applied to optimizing the structure of paper. However, the same methods can be applied in light-scattering studies of Solar-system regoliths or cometary dust, or in any remote-sensing problem involving light scattering in random media with wavelength-scale structures.

Marked ball grinding rests were carried out in the laboratory with a low grade phosphate ore under different experimental conditions. Two types of balls were used, namely high carbon low alloy (HCLA) cast steel and high chrome cast iron. Results of marked ball grinding tests indicated that ball wear increased with time and showed a sharp increase for wet grinding over dry grinding. Ball wear under wet grinding conditions was also influenced by the gaseous atmosphere in the mill. The grinding ball materials could be arranged in the following order with respect to their overall wear resistance: High chrome cast iron > HCLA cast steel balls Methods to minimize ball wear through control of mill atmosphere and addition of flotation reagents are discussed. Effect of grinding media and additions of flotation reagents during grinding on phosphate ore flotation are also discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.

Resumen: Este artículo intenta teorizar acerca de la dinámica entre los medios masivos de comunicación y los gobiernos de los países latinoamericanos. Si bien en la última década los gobiernos atacaron públicamente a los medios de comunicación, se afirma que no se dio por las razones que dicen, sino más bien por asuntos económicos. Por lo tanto, se ha diseñado un modelo utilizando el método de “principal” vs “incumbente”, donde se alcanzará un equilibrio de Nash perfecto en subjuegos. Además de esto, se realiza un repaso por la literatura conocida, y concluye señalando las fortalezas y debilidades del modelo propuesto.

Immersion in various media has different effect on the properties of dental composites, such as sorption, solubility, elution of unreacted monomers, flexural strength, and flexural elastic modulus. In the present work, the effect of immersion in various media and the relationship between the variation of these properties and the components of dental composite were investigated.
