Transmedia as ‘Unmixed Media’ aesthetics

What is ‘transmedia’? This chapter attempts to understand what this phenomenon is from a transhistorical perspective. The transhistorical nature of media combinations is interrogated in light of media specificity and in relation to the key phenomena of Intermedia. Transmedia is argued to be a transhistorical urge towards unifying that which has been artificially estranged.

Social media, audiences, and audience co-creativity in contemporary performance: Restoring balance?

Producers, technicians, performers, audiences and critics are all critical components of the performing arts ecology – critical components of an ecosystem that have to come together into some sort of productive relationship if the performing arts are to be vital, viable and successful. Different performance practices developed in different times, spaces and places do, of course, connect these players in different ways as part of their attempt to achieve their own definition of success, be it based on entertainment, educational, expression, empowerment, or something else. In some contemporary performance practices, social media platforms, applications and processes are seen to have significant potential to restore balance to the relationship between performer and audience, providing audiences with more power to participate in a performance event. In this paper, I investigate prevailing assumptions about social media’s power to democratise performance practice, or, at least, develop more co-creative performance practices in which producers, performers and audiences participate actively before, during and after the event. I focus, in particular, on the use of social media as a means of developing a participatory aesthetic in which an audience member is asked to contribute to the cast of characters, plot or progression of a performance. Although diverse – from performances streamed online, to performances that offer transmedia components the audience can use to learn more about character, context and plot online, to performances that incorporate online voting, liking or linking, to performances that unfold fully online on websites, blogs, microblogs or other social media platforms – what a lot of uses of social media in contemporary performance today share is a desire to encourage audiences to reflect on their role in making, and making meaning, of the event. In this paper I interrogate if, and if so how, this democratises or develops deeper levels of co-creativity in the relationship between producers, performers and audiences.

A theoretical approach to conceptualize information quality in social media

While organizations strive to leverage the vast information generated daily from social media platforms, and decision makers are keen to identify and exploit its value, the quality of this information remains uncertain. Past research on information quality criteria and evaluation issues in social media is largely disparate, incomparable and lacking any common theoretical basis. In attention to this gap, this study adapts existing guidelines and exemplars of construct conceptualization in information systems research, to deductively define information quality and related criteria in the social media context. Building on a notion of information derived from semiotic theory, this paper suggests a general conceptualization of information quality in the social media context that can be used in future research to develop more context specific conceptual models.

Cinema Cities, Media Cities: The Contemporary International Studio Complex

This report, written for the Australian Film Commission (now Screen Australia) is the first major study of the development and role of studio complexes in the spread of film production around the world. The report is divided in to five chapters. First, it examines policy-making around studios, including government support for new facilities around the world. Second, it situates the phenomenon of the contemporary studio complex within the international production ecology. Third, it provides examples of the three types of studio complex: production precinct; cinema city; and media city. Fourth, it describes the networks of production that sustain studios. And fifth it explores the place of the studio in the relationship between 'local' and international production.

The sleeping elephant in the room: Practices and policies regarding sleep-rest time in ECEC

The National Quality Framework (NQF) for Early Childhood Education and Care (ECEC) in Australia identifies the need for services to make provision for each child’s sleep, rest and relaxation within a national early year’s policy framework that also requires that opportunities for learning and physical health are optimised, and that the agency of each child and their family is respected. Against this background, the scheduling of a standard sleep-time in ECEC centres remains a common practice, even in rooms catering for older children for whom daytime sleep may no longer be necessary. This article draws upon existing scholarship to explore the issues and tensions associated with sleep-rest, in the context of Australian curriculum and quality standards documents. We review accounts from educators, parents and children and contemporary views regarding high quality practice in ECEC, with an aim of supporting critical reflection on practice and continuous quality improvement in ECEC.

The favelas through the lenses of photographers: Photojournalism from community and mainstream media organisations

Photographers from community and mainstream media organisations bring the everyday of favela communities to the attention of Rio de Janeiro’s society from different perspectives. While mainstream photojournalists mainly report on favelas from outside to inside, denouncing wrongdoings and human rights abuses, community photographers do it from the opposite direction, from inside to outside, presenting images of the everyday life of favela communities. This paper takes an ethnographic and discursive approach to comparing these two categories of photographers to ask how their different practices can yield benefits for the people living in marginalised communities. Furthermore, by adapting Foucault and Bourdieu’s theories, this study examines photographers’ habitus so as to determine how cultural capital and economic capital that they possess shape their subjectivity and, as such, the fields of community and mainstream photojournalism. This study has no intention of creating polarised distinctions between community and mainstream photojournalism. Instead, the research aims, through the investigation of the working practices, identities, and discourses of photographers from community and mainstream media organisations, to identify the activities and limitations of both community and mainstream in order to build an understanding about how the media ecology works best within both.

How does enterprise social media help retail employees innovate?

An increasing number of organizations have installed enterprise social media (ESM) platforms to allow employees to collaborate, work independently, and to innovate more easily. While research has started to explain how such technologies can lead to improved collaboration and productivity, their role in assisting employees in innovation processes remains unclear. In our research-in-progress we examine the case of a global retail organization that adopted ESM for all employees with the view to foster employee-driven innovation. We report on our on-going data collection and analysis, in which we focus on the salient mechanisms and contingency factors why ESM under some conditions facilitates employee-driven innovation and why under some conditions it does not. We report on on-going data collection, data analysis strategies and emergent findings, and conclude with a brief outlook on our future research strategies.

Strength properties of composite clay balls containing additives from industry wastes as new filter media in water treatment

Pebble matrix filtration (PMF) is a water treatment technology that can remove suspended solids in highly turbid surface water during heavy storms. PMF typically uses sand and natural pebbles as filter media. Hand-made clay pebbles (balls) can be used as alternatives to natural pebbles in PMF treatment plants, where natural pebbles are not readily available. Since the high turbidity is a seasonal problem that occurs during heavy rains, the use of newly developed composite clay balls instead of pure clay balls have the advantage of removing other pollutants such as natural organic matter (NOM) during other times. Only the strength properties of composite clay balls are described here as the pollutant removal is beyond the scope of this paper. These new composite clay balls must be able to withstand dead and live loads under dry and saturated conditions in a filter assembly. Absence of a standard ball preparation process and expected strength properties of composite clay balls were the main reasons behind the present study. Five different raw materials from industry wastes: Red Mud (RM), Water Treatment Alum Sludge (S), Shredded Paper (SP), Saw Dust (SD), and Sugar Mulch (SM) were added to common clay brick mix (BM) in different proportions. In an effort to minimize costs, in this study clay balls were fired to 1100 0C at a local brick factory together with their bricks. A comprehensive experimental program was performed to evaluate crushing strength of composite hand-made clay balls, using uniaxial compression test to establish the best material combination on the basis of strength properties for designing sustainable filter media for water treatment plants. Performance at both construction and operating stages were considered by analyzing both strength properties under fully dry conditions and strength degradation after saturation in a water bath. The BM-75% as the main component produced optimum combination in terms of workability and strength. With the material combination of BM-75% and additives-25%, the use of Red Mud and water treatment sludge as additives produced the highest and lowest strength of composite clay balls, with a failure load of 5.4 kN and 1.4 kN respectively. However, this lower value of 1.4 kN is much higher than the effective load on each clay ball of 0.04 kN in a typical filter assembly (safety factor of 35), therefore, can still be used as a suitable filter material for enhanced pollutant removal.

Fractional models in space for diffusive processes in heterogeneous media with applications in cell motility and electrical signal propagation

This work addresses fundamental issues in the mathematical modelling of the diffusive motion of particles in biological and physiological settings. New mathematical results are proved and implemented in computer models for the colonisation of the embryonic gut by neural cells and the propagation of electrical waves in the heart, offering new insights into the relationships between structure and function. In particular, the thesis focuses on the use of non-local differential operators of non-integer order to capture the main features of diffusion processes occurring in complex spatial structures characterised by high levels of heterogeneity.

Rapid detection of TNT in aqueous media by selective label free surface enhanced Raman spectroscopy

We report rapid and ultra-sensitive detection system for 2,4,6-trinitrotoluene (TNT) using unmodified gold nanoparticles and surface-enhanced Raman spectroscopy (SERS). First, Meisenheimer complex has been formed in aqueous solution between TNT and cysteamine in less than 15 min of mixing. The complex formation is confirmed by the development of a pink colour and a new UV–vis absorption band around 520 nm. Second, the developed Meisenheimer complex is spontaneously self-assembled onto unmodified gold nanoparticles through a stable Au–S bond between the cysteamine moiety and the gold surface. The developed mono layer of cysteamine-TNT is then screened by SERS to detect and quantify TNT. Our experimental results demonstrate that the SERS-based assay provide an ultra-sensitive approach for the detection of TNT down to 22.7 ng/L. The unambiguous fingerprint identification of TNT by SERS represents a key advantage for our proposed method. The new method provides high selectivity towards TNT over 2,4 DNT and picric acid. Therefore it satisfies the practical requirements for the rapid screening of TNT in real life samples where the interim 24-h average allowable concentration of TNT in waste water is 0.04 mg/L.

Investigating marketing managers' perspectives on social media in Chile

Social media has reached global proportions, yet little is known about firms’ engagement with these Web 2.0 technologies in emerging markets within Latin America. The study investigates Chilean marketing managers’ perspectives on social media platforms, the benefits or barriers to their firm’s marketing practices and the impact they have on the immediate marketing environment based on in-depth interviews. Applying Okazaki and Taylor’s (2013) social media framework the findings provide an understanding of social media’s role for Chilean firms in customer engagement, brand image enhancement, return on investment, and meeting consumer needs through time and place. Additional themes emerged on the use of social media through Smartphones and their value for future marketing activities.

Financial institutions using social media – do consumers perceive value?

Purpose The purpose of this paper is to examine consumer perceptions of value of financial institutions using social media to interact with consumers; if overall perceived value predicts a consumer’s intention to adopt, and if intention predicts self-reported adoption of social media to interact with a financial institution; and if perceptions of value in using social media to interact with a financial institution changes over time. Design/methodology/approach Self-administered surveys were run at two time points; 2010 and 2014. Data were analyzed using multiple and mediated regressions, and t-tests. Comparisons are made between the two time points. Findings Perceived usefulness, economic value, and social value predicted overall perceived value, which in turn predicted a consumer’s intention to adopt social media to interact with a financial institution. At Time 2, adoption intention predicted self-reported usage behavior. Finally, there were significant differences between perceptions across Time 1 and 2. Research limitations/implications The implications of the research highlight the importance of overall perceived value in the role of adoption intention, and that at Time 2, adoption intention predicted self-reported adoption to read and share content. A reduction in perceptions of value and intentions from Time 1 to Time 2 could be explained by perceptions of technology insecurity. In future studies, the authors recommend examining inhibitors to adoption including hedonic value. Practical implications The findings suggest that consumers will use social media if the sector creates and clearly articulates consumer value from using social media. The sector also needs to address technology security perceptions to increase usage of social media. Originality/value This paper is one of the first to investigate the consumer’s perspective in social media adoption by financial institutions, by exploring the role of value in consumer adoption and usage of social media.

The security and privacy of usage policies and provenance logs in an Information Accountability Framework

The potential benefits of shared eHealth records systems are promising for the future of improved healthcare. However, the uptake of such systems is hindered by concerns over the security and privacy of patient information. The use of Information Accountability and so called Accountable-eHealth (AeH) systems has been proposed to balance the privacy concerns of patients with the information needs of healthcare professionals. However, a number of challenges remain before AeH systems can become a reality. Among these is the need to protect the information stored in the usage policies and provenance logs used by AeH systems to define appropriate use of information and hold users accountable for their actions. In this paper, we discuss the privacy and security issues surrounding these accountability mechanisms, define valid access to the information they contain, discuss solutions to protect them, and verify and model an implementation of the access requirements as part of an Information Accountability Framework.
