Online fine line : using social media to predict the Big Brother eviction

Reality television, alongside shows such as Q&A – which may be Reality TV in all but name – frequently drives social media conversations about the Australian television industry. Big Brother, currently screening on Channel 9, is consistently among the shows with the highest levels of chatter in that regard. The precise Facebook data is hard to quantify but the Official Big Brother page boasts 805,400 likes and more than 59,000 comments since the start of the series, suggesting it has established a firm presence on that platform too...

Hydrolysis of genotoxic methyl-substituted oxiranes : Experimental kinetic and semiempirical studies

The kinetics of acid-catalyzed hydrolysis of seven methylated aliphatic epoxides - R1R2C(O)CR3R4 (A: R1=R2=R3=R4=H; B: R1=R2=R3=H, R4=Me; C: R1=R2=H, R3=R4=Me; D: R1=R3=H, R2=R4=Me(trans); E: R1=R3=H, R2=R4=Me(cis); F: R1=R3=R4=Me, R2=H; G: R1=R2=R3=R4=Me) - has been studied at 36 ± 1.5°C. Compounds with two methyl groups at the same carbon atom of the oxirane ring exhibit highest rate constants (k(eff) in reciprocal molar concentration per second: 11.0 ± 1.3 for C, 10.7 ± 2.1 for F, and 8.7 ± 0.7 for G as opposed to 0.124 ± 0.003 for B, 0.305 ± 0.003 for D, and 0.635 ± 0.036 for E). Ethylene oxide (A) displays the lowest rate of hydrolysis (0.027 M-1 s-1). The results are consistent with literature data available for compounds A, B, and C. To model the reactivities we have employed quantum chemical calculations (MNDO, AM1, PM3, and MINDO/3) of the main reaction species. There is a correlation of the logarithm k(eff) with the total energy of epoxide ring opening. The best correlation coefficients (r) were obtained using the AM1 and MNDO methods (0.966 and 0.957, respectively). However, unlike MNDO, AM1 predicts approximately zero energy barriers for the oxirane ring opening of compounds B, C, E and G, which is not consistent with published kinetic data. Thus, the MNDO method provides a preferential means of modeling the acidic hydrolysis of the series of methylated oxiranes. The general ranking of mutagenicity in vitro, A > B > C, is in line with the concept that this sequence also gradually leaves the expoxide reactivity optimal for genotoxicity toward reactivities leading to higher biological detoxifications.

Genetic susceptibility to environmental toxicants : the interface between human and experimental studies in the development of new toxicological concepts

The growing knowledge of the genetic polymorphisms of enzymes metabolising xenobiotics in humans and their connections with individual susceptibility towards toxicants has created new and important interfaces between human epidemiology and experimental toxicology. The results of molecular epidemiological studies may provide new hypotheses and concepts, which call for experimental verification, and experimental concepts may obtain further proof by molecular epidemiological studies. If applied diligently, these possibilities may be combined to lead to new strategies of human-oriented toxicological research. This overview will present some outstanding examples for such strategies taken from the practically very important field of occupational toxicology. The main focus is placed on the effects of enzyme polymorphisms of the xenobiotic metabolism in association with the induction of bladder cancer and renal cell cancer after exposure to occupational chemicals. Also, smoking and induction of head and neck squamous cell cancer are considered.

An exploration of NGO and media efforts to influence workplace practices and associated accountability within global supply chains

This paper investigates how social and environmental non-government organisations (NGOs) use the news media in an endeavour to create changes in the social performance and associated accountabilities of multinational buying companies’ (MBCs’) supply chains located in the developing country of Bangladesh. In this research, we explicitly seek the views of senior officers from global and local NGOs operating in Bangladesh, as well as the views of journalists from major global and local news media organisations. Our results show that social and environmental NGOs strategically use the news media in an effort to effect changes in corporate labour practices and related disclosure practices. More particularly, both the NGOs and the news media representatives stated that NGOs would be relatively powerless to create change in corporate without media coverage. This is the first known study to specifically address the joint and complementary role of NGOs and the news media in potentially creating changes in the social and environmental operating and disclosure practices of supply chains emanating from a developing country.

Electrochemical and spectral studies of self-assembled monolayer of 1,8,15,22-tetraaminophthalocyanatocobalt(II) on indium tin oxide surface

Self-assembled monolayer (SAM) of 1,8,15,22-tetraaminophthalocyanatocobalt(II) (4α-CoIITAPc) was prepared on indium tin oxide (ITO) electrode by spontaneous adsorption from dimethylformamide (DMF) solution containing 4α-CoIITAPc. The SAM of 4α-CoIITAPc formed on ITO electrode was characterized by cyclic voltammetry, Raman and UV–visible spectroscopic techniques. The cyclic voltammogram (CV) of 4α-CoIITAPc SAM shows two pairs of well-defined redox peaks corresponding to CoIII/CoII and CoIIIPc−1/CoIIIPc−2. The surface coverage (Γ) was calculated by integrating the charge under the anodic wave corresponding to CoII oxidation and it was found to be 2.25 × 10−10 mol cm−2. Raman spectrum obtained for the SAM of 4α-CoIITAPc on ITO surface shows strong stretching and breathing bands of Pc macrocycle, pyrrole ring and isoindole ring. Further, the –NH2 bending mode of vibration was absent for the SAM of 4α-CoIITAPc on ITO surface which indirectly confirmed that all the amino groups of 4α-CoIITAPc are involved in bonding with ITO surface. UV–visible spectrum for the SAM of 4α-CoIITAPc on ITO surface shows an intense B-band, Q-band and n–π∗ transition with slight broadening when compared to that of 4α-CoIITAPc in DMF.

Dynamic capabilities and performance : an empirical study of audiovisual producers in Europe

This study tests Teece’s conceptualization of dynamic capabilities in the context of small and medium sized firms competing in creative industries, i.e. the European audio-visual production industry. This industry is characterized by immature and evolving markets where firms’ dynamic capabilities are expected to lead to superior innovative performance. Using survey data from audio-visual producers in ten European countries we find that both sensing and seizing capabilities have a positive effect on firms' innovative performance. The effect however, is curvilinear and positive effects appear only when capabilities overcome a threshold level.

Mapping futures for news: Trends, opportunities and challenges for Scotland

The Mapping Futures of News research and seminar programme, sponsored by the Institute for Advanced Studies in 2009-10, addressed those questions, as well as the many more immediate issues facing the Scottish news industry, such as how to survive the current period of often traumatic transition. This document summarises that work, and identifies: Mapping Futures for News: Programme Report iii • Where the main Scottish print and broadcast news media are in 2010, in terms of circulation and ratings figures; • the key trends currently impacting on Scottish news media; • the responses up to now of government and regulators to assist the Scottish media through the present problems; • the responses of the news media themselves.

Synopsis and review of the Australian feature film Deathcheaters, directed by Brian Trenchard-Smith.

From true story to Morning Glory : fantasy and reality in journalism movies

Many movies have been made about journalists, including some of cinema’s all-time classics. Fewer have been made about the process of journalism, however, and fewer still have captured that process in a way which reflects the reality of a hyperactive, stressedout trade that at its best confronts power and risks everything to expose its abuse. Those deemed to come close to that gritty realism regularly feature in those polls of the films journalists themselves think are the best representations of their oft-maligned profession. These are the films in which journalists like to think they see themselves. They are part of the professional mythology of journalistic practice.

Gone Girl and the mediatization of crime

Gone Girl (David Fincher, 2014) will not be remembered for its representation of journalists, although both lead characters are, as the narrative opens in 2012, magazine writers made redundant in the wake of the 2008 global financial crisis. To this extent they personify the “death of journalism” narrative of recent years in the United States, but we never see them in a newsroom or doing journalistic work. The marriage of Nick and Amy Dunne (Ben Affleck and Rosamund Pike) is cast as a victim of, among other things, the downturn in the US economy which accompanied the credit crunch. But this is not the subject of Gone Girl, so much as a context for the marital dysfunctionality at the heart of its plot...

Equilibrium and column studies of iron exchange with strong acid cation resin

The exchange of iron species from iron (III) chloride solutions with a strong acid cation resin has been investigated in relation to a variety of water and wastewater applications. A detailed equilibrium isotherm analysis was conducted wherein models such as Langmuir Vageler, Competitive Langmuir, Freundlich, Temkin, Dubinin Astakhov, Sips and Brouers-Sotolongo were applied to the experimental data. An important conclusion was that both the bottle-point method and solution normality used to generate the ion exchange equilibrium information influenced which sorption model fitted the isotherm profiles optimally. Invariably, the calculated value for the maximum loading of iron on strong acid cation resin was substantially higher than the value of 47.1 g/kg of resin which would occur if one Fe3+ ion exchanged for three “H+” sites on the resin surface. Consequently, it was suggested that above pH 1, various iron complexes sorbed to the resin in a manner which required less than 3 sites per iron moiety. Column trials suggested that the iron loading was 86.6 g/kg of resin when 1342 mg/L Fe (III) ions in water were flowed at 31.7 bed volumes per hour. Regeneration with 5 to 10 % HCl solutions reclaimed approximately 90 % of exchange sites.

Embedded creative workers and creative work in education

This article is concerned with the many connections between creative work and workers, and education work and industries. Employment in the education sector has long been recognised as a significant element in creative workers’portfolio careers. Much has been written, for exam- ple, about the positive contribution of ‘artists in schools’ initiatives. Australian census analyses reveal that education is the most common industry sector into which creative workers are ‘embedded’, outside of the core creative industries. However, beyond case studies and some survey research into arts instruction and instructors, we know remarkably little about in which education roles and sectors creative workers are embedded, and the types of value that they add in those roles and sectors. This article reviews the extant literature on creative work and workers in education, and presents the findings of a survey of 916 graduates from creative undergraduate degrees in Australia. The findings suggest that education work is very common among creative graduates indeed, while there are a range of motivating factors for education work among creative graduates, on average they are satisfied with their careers, and that creative graduates add significant creative-cultural and creative-generic value add through their work.

Creative graduate pathways within and beyond the creative industries

This special issue explores the nuances of graduate creative work, the kinds of value that creative graduates add through work of various types, graduate employability issues for creative graduates, emerging and developing creative career identities and the implications for educators who are tasked with developing a capable creative workforce. Extent literature tends to characterise creative careers as either ‘precarious’ and insecure, or as the engine room of the creative economy. However, in actuality, the creative workforce is far more heterogeneous than either of these positions suggest, and creative careers are far more complex and diverse than previously thought. The task of creative educators is also much more challenging than previously supposed. In this introductory article, we commence by providing a brief overview of the creative labour debates, and the evidence for each position. We present the latest literature in this area that starts to speak to how diverse and complex the landscape of creative work actually is. We then introduce each of the articles in this special issue and indicate how they contribute to a more multi-faceted picture of creative activity, and the lives and career trajectories of graduates from creative degrees.
