Coming soon (to a theatre near you) : the temporality of global film distribution to Australia

This article explores the changing contexts of international film exhibition in Australia over a 20-year period (1989–2009) by examining in some empirical detail Australia’s position in the global flow of films during this time. It argues that, at the most abstract level, distributors are engaged in the management and mediation of time and space in the field of global communications. It is proposed that distributors, through the organisation of temporal differentiation, are explicitly active in the creation of both cultural and commodity value. This is particularly apparent as film distributors explore and engage new methodologies of film release, which emphasise overlapping, intersecting and contradictory temporalities in the cinema experience.

Indigenous communities and new media : questions on the global digital age

Purpose – The purpose of this paper is to look at some of the issues surrounding access to and the use of new media technologies, and questions why this is an area of study that receives a marginal focus in academic work.
Design/methodology/approach – Drawing on previous literature in the area of information and communications technology (ICT) adoption and social exclusion, this paper combines the methodological frameworks adopted by hegemony research and more general studies of new media.
Findings – The paper discusses the impacts of new media use by Indigenous communities, within the framework of discussions about a “global Digital Age”. The paper also briefly looks at the social
implications of new media adoption.
Originality/Value - It questions the assumption that adoption and use of new media is for the "good" or "benefit" of all. It will be of value to researchers of ICT adoption by Indigenous communities.

Climate change regulation : implications for business executives

Purpose – The purpose of this paper is to provide an overarching conceptual decision model that delineates the major issues and decisions associated with carbon regulations that will allow executives to better understand the potential regulatory schemes and implications that may be imposed in the near future.
Design/methodology/approach – The authors use the extant literature as the foundation to develop a conceptual model of the decisions pertaining to climate change regulation that face business executives today.
Findings – This paper suggests four major categories of issues that must be addressed in any climate change regulatory scheme. These include: “scope” – will carbon emission management systems be global or regional; “who pays” – will the consumer or will the supply chain be responsible for the cost of their emissions; “market or compliance-based mechanisms” – will the CO2 emissions system be market-based or a compliance-based regulatory system; and “criteria” – how can credence of the remedy be established – what is necessary for a business initiative to qualify for as a creditable carbon offset?
Research limitations/implications – This paper offers a framework that categories the fundamental decisions that must be made in any climate change regulation. This framework may be useful in advancing research into any of the four categories of decisions and their implications on commerce and the environment. This paper is designed to be managerially useful and in that way does limit its ability to specifically advance many dimensions of research.
Practical implications – The paper offers executives for a simple model of the decisions that must be made to craft an effective climate change regulatory scheme. In addition, it suggests how these decisions may create exploitable economic opportunities for innovative and proactive firms.
Originality/value – This paper adds value to the debate by clarifying the decisions that must be addressed in any climate change regulation scheme.

The relationship between emergence of the shortest path and information value using ant-like agents

Ant-like agents forage between two points. These agents' probabilistic movements are based on the use of two pheromones; one marking trails towards the goal and another marking trails back to the starting point. Path selection decisions are influenced by the relative levels of attractive and repulsive pheromone in each agent's local environment. Our work in [5] evaluates three pheromone perception strategies, investigating path formation speed, quality, directionality, robustness and adaptability under different parameter settings(degree of randomness, pheromone evaporation rate and pheromone diffusion rate). We re-evaluate two of these strategies in terms of the amount of information they provide using Shannon's formulation [3, 4, 8, 9, 12, 14, 15, 16, 17]. We determine information as the difference between uncertainty before and after path selection decisions. Our focus in this paper is on investigating relationships between the emergence of the shortest path and the amount of stigmergic information that exists in the form of pheromone. Agents are deployed centrally and emergence measures are determined using the worst, reference and best cases observed in [5]. Additionally, the amount of local and global information that is available to agents in each movement step is evaluated. Furthermore, Pearson's correlation coefficients between measures of emergence and the amount of information are calculated. The significance of these correlation coefficients is tested using a 2 tailed test at 1% level of significance. Consequently the relationship between the amount of information and emergent behaviour is established. Significant relationships between information and the emergence of the shortest path exist when strong emergent behaviour is present.

Are shocks to national income persistent? New global evidence

Purpose – This paper aims to investigate the integrational properties of real GDP for 125 countries
.
Design/methodology/approach – The paper applies the Kwiatkowski et al. univariate test and a KPSS-type univariate test that accounts for multiple structural breaks – a test procedure proposed by Carrion-i-Silvestre et al. The panel versions of the KPSS-type test, proposed by Carrion-i-Silvestre et al. with and without structural breaks, are also applied.

Findings – The paper finds that, while univariate tests with and without structural breaks provide mixed results on persistence, the panel test suggests that shocks to national output are persistent.

Originality/value – This is a multi-country study that focuses on both developed and developing countries and uses more recent data to provide new and comparable evidence on the persistence of output.

Histological and global gene expression analysis of the ‘lactating’ pigeon crop

Background: Both male and female pigeons have the ability to produce a nutrient solution in their crop for the nourishment of their young. The production of the nutrient solution has been likened to lactation in mammals, and hence the product has been called pigeon ‘milk’. It has been shown that pigeon ‘milk’ is essential for growth and development of the pigeon squab, and without it they fail to thrive. Studies have investigated the nutritional value of pigeon ‘milk’ but very little else is known about what it is or how it is produced. This study aimed to gain insight into the process by studying gene expression in the ‘lactating’ crop.
Results: Macroscopic comparison of ‘lactating’ and non-’lactating’ crop reveals that the ‘lactating’ crop is enlarged and thickened with two very obvious lateral lobes that contain discrete rice-shaped pellets of pigeon ‘milk’. This was characterised histologically by an increase in the number and depth of rete pegs extending from the basal layer of the epithelium to the lamina propria, and extensive proliferation and folding of the germinal layer into the superficial epithelium. A global gene expression profile comparison between ‘lactating’ crop and non-’lactating’ crop showed that 542 genes are up-regulated in the ‘lactating’ crop, and 639 genes are down-regulated. Pathway analysis revealed that genes up-regulated in ‘lactating’ crop were involved in the proliferation of melanocytes, extracellular matrix-receptor interaction, the adherens junction and the wingless (wnt) signalling pathway. Gene ontology analysis showed that antioxidant response and microtubule transport were enriched in ‘lactating’ crop.
Conclusions: There is a hyperplastic response in the pigeon crop epithelium during ‘lactation’ that leads to localised cellular stress and expression of antioxidant protein-encoding genes. The differentiated, cornified cells that form the pigeon ‘milk’ are of keratinocyte lineage and contain triglycerides that are likely endocytosed as very low density lipoprotein (VLDL) and repackaged as triglyceride in vesicles that are transported intracellularly by microtubules. This mechanism is an interesting example of the evolution of a system with analogies to mammalian lactation, as pigeon ‘milk’ fulfils a similar function to mammalian milk, but is produced by a different mechanism.

Recreational value of Southern Bluefin Tuna fishing

Southern bluefin tuna (Thunnus Maccoyii) is a global resource, which is critically endangered. The Committee for the Conservation of Southern Bluefin Tuna sets commercial quota levels for member nations, including Australia, each year. However, southern bluefin tuna is also a popular “trophy” fish with recreational anglers. The size of the total recreational catch, which is not included in the quota, is unknown but thought to be significant. This paper reports the findings of a study designed to estimate the recreational value of the non-commercial southern bluefin tuna catch at Portland, in southwest Victoria. The results indicate that the size of the recreational catch at Portland is considerable and therefore significant in terms of the management of the fishery. Furthermore, the non-market recreational values associated with the fishery are substantial with the on-site recreational use value (consumer surplus) per person per visit estimated to be between $33 and $132 and the on-site annual recreational use value of the fishery for one season is estimated to be between $449,533 and $1,325,124.

Determining binding constants from 1H NMR titration data using global and local methods : a case study using [n]polynorbornane-based anion hosts

From data generated using 1H NMR titrations, different methodologies to calculate binding constants are compared. The ‘local’ analysis method that uses only a single isotherm (only one H-bond donor) is compared against the ‘global’ method (that includes many or all H-bond donors). The results indicate that for simple systems both methods are suitable, however, the global approach consistently provides a K a value with uncertainties up to 30% smaller. For more complex binding, the global analysis method gives much more robust results than the local methods. This study also highlights the need to explore several different modes when data do not fit well to a simple 1:1 complexation model and illustrates the need for better methods to estimate uncertainties in supramolecular binding experiments.

Exploring the global and local networks of national information system integration initiatives : a case study of national cultural collection integration from an actor-network perspective

Australian Museums Online (AMOL) was the earliest attempt to make Australia’s distributed cultural collections accessible from a single online resource. Despite early successes, significant achievements and the considerable value it offered certain groups, the project ran into operational difficulties and was eventually discontinued. By using Actor-Network Theory and analysing the global and local actor-networks, it is revealed that although the project originated from large, state museums, buy-in was restricted to individuals, rather than institutions and the most significant value was for smaller, regional institutions. Furthermore, although the global networks that governed the project could translate their visions through the local production networks, because the network’s underlying weaknesses were never addressed, over time this destablised the global networks. This case study offers advice for projects attempting to consolidate data sources from disparate sources, and highlights the importance of individual actors in championing the project.

Reading the local and global: teaching literature in secondary schools in Australia

Recently Australia has witnessed a revival of concern about the place of Australian literature within the school curriculum. This has occurred within  a policy environment where there is increasing emphasis on Australia’s place  in a world economy, and on the need to encourage young people to think of  themselves in a global context. These dimensions are reflected in the  recently published Australian Curriculum: English, which requires students to read texts of ‘enduring artistic and cultural value’ that are drawn from  'world and Australian literature’. No indication, however, is given as to how the reading and literary interpretation that students do might meaningfully be framed by such categories. This essay asks: what saliences do the categories of the ‘local’, the ‘national’ and the ‘global’ have when  young people engage with literary texts? How does this impact on teachers’  and students’ interpretative approaches to literature? What place does a  ‘literary’ education, whether conceived in ‘local’, 'national’ or ‘global’  terms, have in the twenty-first century?

Developing an analytical framework to assess the uncertainty and flexibility mismatches across the supply chain

Purpose: The purpose of this paper is to discuss how decisions regarding organisational flexibility can be improved through targeted resource allocation, by focusing on the supply chain's level of uncertainty exposure. Specifically, the issue of where and in what ways flexibility has been incorporated across the organisation's supply chain is addressed. Design/methodology/approach: A two-phase methodology design based on literature review and case study was used. Using 83 journal articles in the areas of uncertainty and flexibility an analytical process for assessing uncertainty-flexibility mismatches was developed. Furthermore, results from ten interviews with senior/middle managers within the Australian manufacturing sector were used to provide preliminary insights on the usefulness and importance of the analytical process and its relationship with organisational practice. Findings: The paper emphasises the importance of having a systematic and encompassing view of uncertainty-flexibility mismatches across the supply chain, as well as the significance of socio-technical engagement. The paper both conceptually and empirically illustrates how, using a structured analytical process, flexibility requirements across the supply, process, control and demand segments of a supply chain might be assessed. A four-step analytical process was accordingly developed and, its application, usefulness and importance discussed using empirical data. Practical implications: The analytical process presented in this paper can assist managers to obtain a comprehensive overview of supply chain flexibility when dealing with situations involving uncertainty. This can facilitate and improve their decision-making with respect to prioritising attention on identified flexibility gaps in order to ensure stability of their performance. Originality/value: The paper presents a supply chain-wide discussion on the difficulties that uncertainty brings to organisations, and how organisational flexibility might serve to moderate those challenges for supply chain management. It discusses how to identify the flexibility gap and proposes an original analytical process for systematic assessment of uncertainty-flexibility mismatches. © Emerald Group Publishing Limited.

Adopting global virtual engineering teams in AEC Projects: a qualitative meta-analysis of innovation diffusion studies

Purpose - This study aims to present an integrated conceptual model in order to highlight the major aspects of diffusion of innovations in the architecture, engineering and construction (AEC) context. To this end, a critical review of literature is conducted, accompaniedbysynthesising the findings of previous studies. The driving force behind this study is stemmed from the fragmentation of literature on innovation diffusion, and paucity of research on diffusion of Global Virtual Engineering Teams (GVETs) as the platform formany technological innovations in relevant literature. Thus, the present study is intended to facilitate filling the gap in GVETs literature. That is, the proposed model will offer a foundation for academia for grounding studies on any innovation including GVETs in the literature on innovation diffusion in the AEC context. Design/methodology/approach - This paper draws upon the qualitative meta-analysis approach encompassing a critical review of the relevant literature. To this end, the review builds upon studies found within 15 prestigious journals in AEC. The domain of this review was confined to areas described as "innovation", "innovation diffusion" and "innovation adoption", along with keywords used within a broad review of recently published GVETs literature. The rigour of review is augmented by incorporating 35 authoritative works from other disciplines published in 21 well-known journals in the manufacturing, business and management fields. Moreover, the study deploys the peer-debriefing approach through conducting unstructured interviews with five Australian scholars to verify a model presenting an aggregated summary of previous studies. Findings - The key findings of the study include the following items: Synthesising the fragmented studies on innovation diffusion in the AEC context. In doing so, a model capturing the major aspects affecting diffusion of an innovation in AEC projects is presented; providing a foundation to address the drawbacks of previous studies within the sphere of GVETs, based on the developed model. Research limitations/implications - The developed model was only enhanced using a small sample size of academics, as such not empirically validated. Originality/value - As possibly, the first literature review of innovation in the AEC context, this paper contributes to the sphere by sensitising the AEC body of knowledge on innovation diffusion as a concise conceptual model, albeit verified through the peer-debriefing approach. This study will also further establish the research field in AEC on GVETs along with other methods reliant on virtual working such as building information modelling (BIM) through providing an expanded foundation for future inquiries and creation of knowledge.

Evolutionary history and leaf succulence as explanations for medicinal use in aloes and the global popularity of Aloe vera

BACKGROUND: Aloe vera supports a substantial global trade yet its wild origins, and explanations for its popularity over 500 related Aloe species in one of the world's largest succulent groups, have remained uncertain. We developed an explicit phylogenetic framework to explore links between the rich traditions of medicinal use and leaf succulence in aloes. RESULTS: The phylogenetic hypothesis clarifies the origins of Aloe vera to the Arabian Peninsula at the northernmost limits of the range for aloes. The genus Aloe originated in southern Africa ~16 million years ago and underwent two major radiations driven by different speciation processes, giving rise to the extraordinary diversity known today. Large, succulent leaves typical of medicinal aloes arose during the most recent diversification ~10 million years ago and are strongly correlated to the phylogeny and to the likelihood of a species being used for medicine. A significant, albeit weak, phylogenetic signal is evident in the medicinal uses of aloes, suggesting that the properties for which they are valued do not occur randomly across the branches of the phylogenetic tree. CONCLUSIONS: Phylogenetic investigation of plant use and leaf succulence among aloes has yielded new explanations for the extraordinary market dominance of Aloe vera. The industry preference for Aloe vera appears to be due to its proximity to important historic trade routes, and early introduction to trade and cultivation. Well-developed succulent leaf mesophyll tissue, an adaptive feature that likely contributed to the ecological success of the genus Aloe, is the main predictor for medicinal use among Aloe species, whereas evolutionary loss of succulence tends to be associated with losses of medicinal use. Phylogenetic analyses of plant use offer potential to understand patterns in the value of global plant diversity.
