The role of the press is underpinned by a concern for public welfare, and the discourses and debates in journalism practice and theory stem from the notion that the press is one of the pillars of a democracy and an essential element of the public sphere (Rosen, 2005; Dahlgren and Sparks, 1991). The public sphere, in turn, is linked to the theory of modernisation and the development agenda of a society, where the media are expected to play an important function as watchman, policy disseminator and teacher (Schramm, 1964). This article looks at citizen journalism’s potential to provide yet another opportunity to disadvantaged communities in India to communicate with the world, via information and communication technologies. The new media also open up the possibility of these earlier disenfranchised communities becoming partners in the country’s development and democratic agenda. This is a discussion paper based on a survey of initiatives undertaken by various community groups in India to provide a voice to local communities who would otherwise remain silent. It explores the impact of these citizen journalism initiatives on local communities vis-à-vis their effectiveness as a tool for development and social change, and argues that the growth and success of these initiatives around the world, though piecemeal, should become an important part of discourse concerning the role of journalism in society.

The incidence of gestational diabetes is increasing worldwide, exposing large numbers of infants to hyperglycaemia whilst in utero. This exposure may have a long-term negative impact on the cardiovascular health of the offspring. Novel methods to assess cardiovascular status in the neonatal period are now available—including measuring arterial intima-media thickness and retinal photography. These measures will allow researchers to assess the relative impact of intrauterine exposures, distinguishing these from genetic or postnatal environmental factors. Understanding the long-term impact of the intrauterine environment should allow the development of more effective health policy and interventions to decrease the future burden of cardiovascular disease. Initiating disease prevention aimed at the developing fetus during the antenatal period may optimise community health outcomes.

Objective. To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents’ leisure-time physical activity (PA).

Methods. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006–07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA.

Results. Perceived availability of sport facilities was positively (ORboys = 1.17; ORgirls = 1.26), and that of computer/Internet negatively (ORboys = 0.48; ORgirls = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (ORgirls = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (ORboys = 1.26; ORgirls = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (ORboys = 0.60; ORgirls = 0.54).

Conclusions. Perceived availability of sport facilities in the neighborhood may positively impact on adolescents’ level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component.

This paper reflects on the use of Twitter and Facebook at the PILCH Homeless Persons' Legal Clinic (HPLC), and the lessons for social change lawyers. While these two forms of social media have been useful tools in the HPLC's mission to address the systemic and structural issues that impact on people experiencing homelessness in Victoria, Australia, there have been salutary lessons in their deployment, engagement and impact. This paper, written in autoethnographic form by a former HPLC manager, reflects on the costs and benefits of these new media forms for ‘social change lawyering’.

Legal academics are not only teachers but also creators of knowledge. The role of an academic includes a responsibility to share this knowledge through engagement not just of their students, but also of the wider community. In addition, there is increasing emphasis on legal academics having to account for the so-called ‘impact’ of research. In selecting both the topic of their research and the mode of publication of their knowledge, legal academics act as gatekeepers. There is an increasing critique of the existing paradigm of research publication and its emphasis on the metrics of impact. This critique recognises the limitations of the commercial publication paradigm in the present context of open access and the vast array of citizen-mediated platforms for dissemination of legal knowledge and innovation. Susskind (Tomorrow’s Lawyers 2013) for example identifies expert crowd-sourced legal information as breaking down barriers to access to justice. Tracking their experience with publication of a paper on social media in legal education from the ALTA conference in 2012, the authors share an auto-ethnographic account of their insights into the potential for both impact and engagement of a diverse audience in their research. This highlights the ways in which various media can be used strategically to redefine the role of the gatekeeper.

Recent two dimensional nuclear magnetic resonance (NMR) techniques access exchange in pore structures through surface relaxation and diffusion based relaxation [1-4]. This research applies these techniques to measure pore changes due to biofilm growth and the impact this growth has on diffusion transport. The porous media used in this study are model beadpacks constructed from borosilicate glass beads with diameters approximately 100 um. This research shows that through changes in the relaxation rates, NMR can be used to verity biofilm growth in porous media

This book makes a new and significant argument that Indian news media is no longer just an observer but an active participant in the events that direct the nation. It explores the changing role of Indian news media and their performance in the past 25 years by closely examining media coverage of some landmark events within the context of India’s globalising polity, which has led to privatisation, widespread engagement with new communication technologies, and the rise of individualism. The challenges of globalisation have caused significant changes in news processes and procedures, which this volume details by examining media’s coverage of events and issues such as paid news, anti-graft movement, sting journalism, Delhi gang-rape protest, politics-media nexus and neo-liberalism’s impact on the industry’s performance.
The book places Indian media’s evolution in the context of economic, political and sociological developments in the country. It takes a multi-disciplinary approach to evaluate reportage in a multitude of media platforms. The theoretical exploration of the changes in the Indian media landscape draws from academic disciplines of ‘media studies’, ‘journalism,’ ‘cultural studies’ and ‘sociology’. This book follows the authors’ earlier work, titled Indian Media in a Globalised World (SAGE/2010).

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.

We examine the relationship between atmospheric and water pollution, traffic congestion, access to parkland and personal well-being using a survey administered across six Chinese cities in 2007. In contrast to existing studies of well-being determinants by economists which typically employ single-item indicators, we use the Personal Well-being Index (PWI). We also employ the Job Satisfaction Survey (JSS) to measure job satisfaction, which is one of the variables for which we control when examining the relationship between environmental surroundings and personal well-being. Previous research by psychologists has shown the PWI and JSS to have good psychometric properties in western and Chinese samples. A robust finding is that in cities with higher levels of atmospheric pollution and traffic congestion, respondents report lower levels of personal well-being ceteris paribus. Specifically, we find that a one standard deviation increase in suspended particles or sulphur dioxide emissions is roughly equivalent to a 12-13% reduction in average monthly income in the six cities. © 2010 Springer Science+Business Media, LLC.

Demographic characteristics associated with gambling participation and problem gambling severity were investigated in a stratified random survey in Tasmania, Australia. Computer-assisted telephone interviews were conducted in March 2011 resulting in a representative sample of 4,303 Tasmanian residents aged 18 years or older. Overall, 64.8 % of Tasmanian adults reported participating in some form of gambling in the previous 12 months. The most common forms of gambling were lotteries (46.5 %), keno (24.3 %), instant scratch tickets (24.3 %), and electronic gaming machines (20.5 %). Gambling severity rates were estimated at non-gambling (34.8 %), non-problem gambling (57.4 %), low risk gambling (5.3 %), moderate risk (1.8 %), and problem gambling (.7 %). Compared to Tasmanian gamblers as a whole significantly higher annual participation rates were reported by couples with no children, those in full time paid employment, and people who did not complete secondary school. Compared to Tasmanian gamblers as a whole significantly higher gambling frequencies were reported by males, people aged 65 or older, and people who were on pensions or were unable to work. Compared to Tasmanian gamblers as a whole significantly higher gambling expenditure was reported by males. The highest average expenditure was for horse and greyhound racing ($AUD 1,556), double the next highest gambling activity electronic gaming machines ($AUD 767). Compared to Tasmanian gamblers as a whole problem gamblers were significantly younger, in paid employment, reported lower incomes, and were born in Australia. Although gambling participation rates appear to be falling, problem gambling severity rates remain stable. These changes appear to reflect a maturing gambling market and the need for population specific harm minimisation strategies. © 2014 Springer Science+Business Media New York.

Objective: To determine the impact of tobacco control policies and mass media campaigns on smoking prevalence in Australian adults.
Methods: Data for calculating the average monthly prevalence of smoking between January 2001 and June 2011 were obtained via structured interviews of randomly sampled adults aged 18 years or older from Australia’s five largest capital cities (monthly mean number of adults interviewed: 2375). The influence on smoking prevalence was estimated for increased tobacco taxes; strengthened smoke-free laws; increased monthly population exposure to televised tobacco control mass media campaigns and pharmaceutical company advertising for nicotine replacement therapy (NRT), using gross ratings points; monthly sales of NRT, bupropion and varenicline; and introduction of graphic health warnings on cigarette packs. Autoregressive integrated moving average (ARIMA) models were used to examine the influence of these interventions on smoking prevalence.
Findings: The mean smoking prevalence for the study period was 19.9% (standard deviation: 2.0%), with a drop from 23.6% (in January 2001) to 17.3% (in June 2011). The best-fitting model showed that stronger smoke-free laws, tobacco price increases and greater exposure to mass media campaigns independently explained 76% of the decrease in smoking prevalence from February 2002 to June 2011.
Conclusion: Increased tobacco taxation, more comprehensive smoke-free laws and increased investment in mass media campaigns played a substantial role in reducing smoking prevalence among Australian adults between 2001 and 2011.

Physical inactivity is a potent stimulus for vascular remodeling, leading to a marked decrease in conduit artery diameter. However, little is known about the impact of physical inactivity on artery wall thickness or wall:lumen ratio or the potential of exercise countermeasures to modify artery wall thickness. The purpose of the study was to examine the impact of 60 days of bed rest, with or without exercise countermeasures, on carotid and superficial femoral artery wall thickness. Eighteen men were assigned to bed rest (second Berlin Bed Rest Study) and randomly allocated to control, resistive exercise, or resistive vibration exercise. Both exercise countermeasures were applied 3 times per week while the subjects were in the supine position on the bed. Sonography was used to examine baseline diameter and wall thickness of the carotid and femoral arteries. Bed rest decreased diameter of the superficial femoral artery (P=0.001) but not the carotid artery (P=0.29). Bed rest induced a significant increase in carotid and superficial femoral artery wall thickness (P=0.007 and 0.03) and wall:lumen ratio (P=0.009 and 0.001). Exercise prevented the increase in wall thickness of the carotid artery. In addition, exercise partly prevented the increased wall:lumen ratio in the superficial femoral artery. In conclusion, 8 weeks of bed rest resulted in approximately 20% increase in conduit artery wall thickness. Exercise countermeasures completely (carotid artery) or partly (superficial femoral artery) abolished the increase in wall thickness. These findings suggest that conduit artery wall thickness, a vascular characteristic associated previously with atherosclerosis, can rapidly adapt to physical inactivity and exercise in humans.

This paper investigates occupational stressors amongst media personnel assigned to work on covering the Iraq War via interviews with 54 journalists from the BBC and Reuters, who worked in Iraq between February and April 2003. A range of stressors were identified that could be categorized into three main themes, control over the situation, support from management and grief from the death of colleagues. Journalists not embedded with military units were more likely to report negative physical and emotional health outcomes. The study concludes that hazardous work environments do not, by themselves, cause stress and poor job satisfaction. Rather, organizational factors, the imbalance between the ability to make decisions about how to carry out their job effectively and the perceived rewards of working in such environments appear to have a greater impact on work related stress.

Reporting about combat sports generates much discussion within the broader community. Many opinions abound and views impact on the acceptance of these types of sports in society. Within Australia, the introduction of Ultimate Fighting Championship (UFC) contests has generated significant debate. This debate has been presented in the media reflecting political, social and moral arguments about the value or social acceptance of this sporting activity. This research explores the manner in which the media frames the reporting into UFC in Australia. A process for framing newspaper articles is broken down and adopted through analysis of 68 articles drawn from two major Australian National newspapers. Themes that emerged included Defining and Legitimizing the Sport, Growth and Economic Benefit, Image and Impact on Society and Political and Government Factors. Upon establishing these themes, it was apparent these presented a Conflict Frame.
