The simple yet complex development of social and participatory media for classroom learning : building a hybrid learning environment through action research

This paper reports on part of a teacher/researcher’s PhD action research study. It explains the complexity of features that social media brings to the teaching and learning process while discussing the simplicity and power of its use. Through the action research cycle, learning programs were designed to take advantage of the unique communicative methods offered by social media and web 2.0 whilst maintaining the value of face-to-face learning. Students used social media spaces such as blogs, groups and discussion forums as well as developing their own profiles and avatars to communicate online by making friends, leaving comments and uploading content which included publishing, peer reviewing and self assessment. The author argues that, by designing learning that valued and combined the attributes of social media, Web 2.0 and face-to-face teaching she was able to produce a more student-centred approach; hence, developing a ‘Hybrid’ learning environment which supported many 21st Century skills.

The Iraqi Federation of Oil Unions : protests and public power in post-Saddam Iraq

Since the democratic elections held across Iraq in 2005 and 2010 much attention has understandably been paid to the new Iraqi government. Unfortunately, it has become increasingly clear that much of Iraq’s political elite are practising the type of governance referred to in the literature on other Arab states alternatively as ‘liberalised autocracy’ (Brumberg, 2002), ‘semi-authoritarianism’ (Ottaway, 2003) or ‘pluralised authoritarianism’ (Posusney & Angrist, 2005). That is to say, that the Iraqi government actually utilises (and controls) nominally democratic mechanisms such as elections, media freedoms, political opposition and civil society as part of their strategy to retain power. This is perhaps best demonstrated via the nine month political stalemate that followed the March 2010 elections and PM Maliki’s refusal to step down despite having narrowly lost the election. Not surprisingly, the Iraqi people have become increasingly disillusioned and critical of their political leaders – hence the mass protests that have swept across Iraq in the context of the popular Arab Revolutions of 2010-11.

However, these latest Iraqi protests are only the most recent and overt sign of the hidden geographies that are agitating towards democracy in this deeply troubled and increasingly authoritarian state. Since the invasion of 2003, a complex array of political, religious and ethno-sectarian factions have formed civil society movements; uncensored news has been consumed across the nation; ordinary citizens have taken to the streets to protest key government decisions; and various local councils have been formed, deliberating on key decisions facing their immediate communities (Davis, 2004, 2007). Given this context, this chapter focuses on the specific case of the Iraqi Federation of Oil Unions (IFOU), Iraq’s largest and most powerful independent workers union. The IFOU has repeatedly taken the Iraqi government to task over their poor pay and the dangerous nature of their work, as well as the government’s initial kowtowing to US plans to privatise the entire Iraqi oil sector. To do this, the IFOU have utilised a variety of very democratic mechanisms including peaceful strikes and protests, media campaigns and political lobbying. Such moves have met with mixed results in Baghdad – at times the central government has pandered to the requests of IFOU, but it has also gone as far as issuing arrest warrants for its senior members. The IFOU therefore serve as an interesting example of public power in Iraq and may well pose one of the greatest challenges to rising authoritarianism there.

'Catastrophic failure' theories and disaster journalism : evaluating media explanations of the Black Saturday bushfires

 In recent decades, academic researchers of natural disasters and emergency management have developed a canonical literature on ‘catastrophe failure’ theories such as disaster responses from US emergency management services (Drabek, 2010; Quarantelli, 1998) and the Three Mile Island nuclear power plant (Perrow, 1999). This article examines six influential theories from this field in an attempt to explore why Victoria’s disaster and emergency management response systems failed during Australia’s Black Saturday bushfires. How well, if at all, are these theories understood by journalists, disaster and emergency management planners, and policy-makers? In examining the Country Fire Authority’s response to the fires, as well as the media’s reportage of them, we use the 2009 Black Saturday bushfires as a theory-testing case study of failures in emergency management, preparation and planning. We conclude that journalists can learn important lessons from academics’ specialist knowledge about disaster and emergency management responses.

Drawing on a diverse range of case studies from the worlds of film, music, television, and sports, and featuring topical, current and popular celebrity examples, the book stands as a pertinent examination of the influence that celebrity has on the way people place themselves in the modern world.

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.

Celebrity and power : fame in contemporary culture

Through a new introduction for this edition, Marshall investigates the viewing public's desire to associate with celebrity and addresses the explosion of instant access to celebrity culture, bringing famous people and their admireres closer than ever before.  He explores the concept of the new public intimacy: a product of social media in which celebrities from lady Gaga to Barack Obama are expected to continuously campaing for audiences in new ways. The new introduction also details the development of celebrity studies and the need for research into the construction of persona in contemporary culture as the dimension of publicizing the self has expanded through online culture.

Naming and shaming: a report on media shaming for minor crimes in Victoria

This exploratory study examines the power of the news media to publicly name ordinary people who receive non-convictions for committing minor crimes. If a magistrate imposes a non-conviction, it means the offender is guilty, but gets a chance to reform away from the public gaze. They are not required to reveal the crime in any job application, and it does not restrict them from overseas travel. This report argues that the power of media to report non-convictions is an issue of national importance in this changing digital landscape because the news media can impose relatively permanent public records, especially in digital space, that detail's one's minor misdemeanour.

Adoption of social media as a communication medium : a study of theoretical foundations

The continuing popularity and adoption of social media by the general public and the realisation of its potential customer engagement power by business, is highlighting the importance of social media to ongoing business activities and strategies. However, current research that is more focused around the potential power of social media generates little debate of the adoption factors driving public use of social media as a communication medium. Even though businesses have an opportunity to broaden their reach by adding social media to the communication strategic-mix, the dearth of informed discussions relating to theoretical underpinnings associated with the public adaptation of social media as a communication medium fails to clearly inform strategic business decisions regarding adoption decision-making. This research study conducted in the Australian context queries established theoretical frameworks by asking the question; what theoretical foundations do influence the social media adoption by the intended audience of communication?

Friend or foe? Regional newspapers and the power of Facebook

This paper examines how some regional newspapers in Australia are engaging with the social media juggernaut Facebook and the effects of this on their relationships with audiences in a digital world. We highlight how terms such as ‘friend’ and ‘community’ mask complex power struggles taking place across these two media platforms. On the one hand, Facebook can facilitate public conversation and widen the options for journalists to access information but, on the other, it has become a competitor for advertising revenue as news outlets struggle to find a business model for online spaces. We suggest that newspapers and journalists are facing challenges in navigating the complexities of a platform that crosses public/private domains at a time when the very nature of ‘private’ and ‘public’ is being contested. The paper adopts a ‘pooled case comparison’ approach to research, drawing on data from two separate Australian studies that examine regional newspapers in a digital landscape. The research draws on interviews with journalists and editors in Australia across three states and on focus groups and interviews with newspaper readers in Victoria.

Composite resin color stability: influence of light sources and immersion media

Objective: This study evaluated the influence of light sources and immersion media on the color stability of a nanofilled composite resin. Material and Methods: Conventional halogen, high-power-density halogen and high-power-density light-emitting diode (LED) units were used. There were 4 immersion media: coffee, tea, Coke (R) and artificial saliva. A total of 180 specimens (10 mm x 2 mm) were prepared, immersed in artificial saliva for 24 h at 37 +/- 1 degrees C, and had their initial color measured with a spectrophotometer according to the CIELab system. Then, the specimens were immersed in the 4 media during 60 days. Data from the color change and luminosity were collected and subjected to statistical analysis by the Kruskall-Wallis test (p<0.05). For immersion time, the data were subjected to two-way ANOVA test and Fisher's test (p<0.05). Results: High-power-density LED (Delta E=1.91) promoted similar color stability of the composite resin to that of the tested halogen curing units (Jet Lite 4000 plus - Delta E=2.05; XL 3000 - Delta E=2.28). Coffee (Delta E=8.40; Delta L=-5.21) showed the highest influence on color stability of the studied composite resin. Conclusion: There was no significant difference in color stability regardless of the light sources, and coffee was the immersion medium that promoted the highest color changes on the tested composite resin.

Asymmetrical penetration of microwave in a conducting media and determination of microwave conductivity for very thin samples using electron spin resonance

Dyson's theory of conduction electron spin resonance (CESR) has been used in the limit d less than or equal to delta (d being the thickness of the sample and delta the skin depth of the microwave field) to obtain the microwave conductivity from the (A/B) ratio of the CESR absorbed power derivative. In this work we calculate the CESR absorbed power derivative using Kaplan's approach and show that the (A/B) ratio can be enhanced if asymmetrical penetration of microwave is used, which means that the microwave field enters into the sample from one of the faces. Therefore, the determination of the microwave conductivity from the (A/B) ratio of the CESR line can be performed for thinner samples. Experimentally, asymmetrical penetration can be obtained if one of the sample's faces is covered with a thin gold layer. The determination of microwave conductivity in conducting polymers films is among the possible applications of this method. (C) 2001 Elsevier B.V. Ltd. All rights reserved.

Assessment and statistics of Brazilian hydroelectric power plants: Dam areas versus installed and firm power

The Brazilian relief, predominantly composed by small mountains and plateaus, contributed to formation of rivers with high amount of falls. With exception to North-eastern Brazil, the climate of this country are rainy, which contributes to maintain water flows high. These elements are essential to a high hydroelectric potential, contributing to the choice of hydroelectric power plants as the main technology of electricity generation in Brazil. Though this is a renewable source, whose utilized resource is free, dams must to be established which generates a high environmental and social impact. The objective of this study is to evaluate the impact caused by these dams through the use of environmental indexes. These indexes are ratio formed by installed power with dam area of a hydro power plant, and ratio formed by firm power with this dam area. In this study, the greatest media values were found in South, Southeast, and Northeast regions respectively, and the smallest media values were found in North and Mid-West regions, respectively. The greatest encountered media indexes were also found in dams established in the 1950s. In the last six decades, the smallest indexes were registered by darns established in the 1980s. These indexes could be utilized as important instruments for environmental impact assessments, and could enable a dam to be established that depletes an ecosystem as less as possible.
