Intersubjectivity is an important concept in psychology and sociology. It refers to sharing conceptualizations through social interactions in a community and using such shared conceptualization as a resource to interpret things that happen in everyday life. In this work, we make use of intersubjectivity as the basis to model shared stance and subjectivity for sentiment analysis. We construct an intersubjectivity network which links review writers, terms they used, as well as the polarities of the terms. Based on this network model, we propose a method to learn writer embeddings which are subsequently incorporated into a convolutional neural network for sentiment analysis. Evaluations on the IMDB, Yelp 2013 and Yelp 2014 datasets show that the proposed approach has achieved the state-of-the-art performance.

BACKGROUND: The aim of this country-wide study was to link individual health and behavioural data with area-level spatial data to examine whether the body mass index (BMI) of adults was associated with access to recreational physical activity (PA) facilities by different modes of transport (bus, car, walking, cycling) and the extent to which any associations were mediated by PA participation. METHODS: Data on individual objectively-measured BMI, PA (number of days of (a) ≥20 min of moderate-to-vigorous PA, and (b) ≥15 min of sport or exercise, in previous 4 weeks), and socio-demographic characteristics were obtained from a nationally representative sample of 6365 adults. The number of accessible PA facilities per 1,000 individuals in each small area (data zones) was obtained by mapping a representative list of all fixed PA facilities throughout mainland Scotland. A novel transport network was developed for the whole country, and routes on foot, by bike, by car and by bus from the weighted population centroid of each data zone to each facility were calculated. Separate multilevel models were fitted to examine associations between BMI and each of the 24 measures of accessibility of PA facilities and BMI, adjusting for age, gender, longstanding illness, car availability, social class, dietary quality and urban/rural classification. RESULTS: We found associations (p < 0.05) between BMI and 7 of the 24 accessibility measures, with mean BMI decreasing with increasing accessibility of facilities-for example, an estimated decrease of 0.015 BMI units per additional facility within a 20-min walk (p = 0.02). None of these accessibility measures were found to be associated with PA participation. CONCLUSIONS: Our national study has shown that some measures of the accessibility of PA facilities by different modes of transport (particularly by walking and cycling) were associated with BMI; but PA participation, as measured here, did not appear to play a part in this relationship. Understanding the multi-factorial environmental influences upon obesity is key to developing effective interventions to reduce it.

Nucleobase-functionalized polymers are widely used in the fields of supramolecular chemistry and self-assembly, and their development for biomedical applications is also an area of interest. They are usually synthesized by tedious multistep procedures. In this study, we assess adenine as an organoinitiator/ organocatalyst for the ring-opening polymerization of lactide. L-Lactide can be quantitatively polymerized in the presence of adenine. Reaction conditions involving short reaction times and relatively low temperatures enable the access to adenine end-capped polylactide in a simple one-step procedure, in bulk, without additional catalyst. DFT calculations show that the polymerization occurs via hydrogen bond catalysis. The mechanism involves (i) a hydrogen bond between the NH9 of adenine and the carbonyl moiety of lactide, leading to an electron deficient carbon atom, and (ii) a second hydrogen bond between the N3 of adenine and the NH2 of a second adenine molecule, followed by a nucleophilic attack of the latter activated amine on the former electron deficient carbon on the monomer. For longer reaction times and higher temperatures, macrocyclic species are formed, and a mechanism involving the imidazole ring of adenine is proposed based on literature studies. Depending on the reaction conditions, adenine can thus be considered as an organoinitiator or an organocatalyst for the ring-opening polymerization of lactide.

In dynamic environments, firms seek to build capabilities which will permit them to become innovation and change ready. Programs offered by intermediaries, while varying greatly in content and format, are designed to support those firms wishing to enhance their competitiveness. Firms which participate in intermediary programs have displayed their willingness to overcome deficiencies or barriers to competitiveness through acquiring knowledge which is external to the firm. This paper reports on interviews with 24 firms who were involved in a MAP or TAP program offered by QMI Solutions. The findings of the research suggest that knowledge intermediaries serve to disrupt organisational paths and in so doing establish mechanisms for ongoing learning and change. They do this first by disrupting the firm with a positive learning experience and also by establishing processes for developing new relationships and access to knowledge which are critical for learning and change. It is the experience of learning through knowledge exchange which can trigger the pursuit of new paths and it is the processes involving new relations and knowledge processing that provides the micro-foundations for ongoing learning and change. This suggests that the role of intermediaries goes well beyond merely knowledge transfer to include longer term effects on the capability of organisations to innovate, which is critical to economic competitiveness and the survival rate of firms.

Queensland University of Technology (QUT) is faced with a rapidly growing research agenda built upon a strategic research capacity-building program. This presentation will outline the results of a project that has recently investigated QUT’s research support requirements and which has developed a model for the support of eResearch across the university. QUT’s research building strategy has produced growth at the faculty level and within its research institutes. This increased research activity is pushing the need for university-wide eResearch platforms capable of providing infrastructure and support in areas such as collaboration, data, networking, authentication and authorisation, workflows and the grid. One of the driving forces behind the investigation is data-centric nature of modern research. It is now critical that researchers have access to supported infrastructure that allows the collection, analysis, aggregation and sharing of large data volumes for exploration and mining in order to gain new insights and to generate new knowledge. However, recent surveys into current research data management practices by the Australian Partnership for Sustainable Repositories (APSR) and by QUT itself, has revealed serious shortcomings in areas such as research data management, especially its long term maintenance for reuse and authoritative evidence of research findings. While these internal university pressures are building, at the same time there are external pressures that are magnifying them. For example, recent compliance guidelines from bodies such as the ARC, and NHMRC and Universities Australia indicate that institutions need to provide facilities for the safe and secure storage of research data along with a surrounding set of policies, on its retention, ownership and accessibility. The newly formed Australian National Data Service (ANDS) is developing strategies and guidelines for research data management and research institutions are a central focus, responsible for managing and storing institutional data on platforms that can be federated nationally and internationally for wider use. For some time QUT has recognised the importance of eResearch and has been active in a number of related areas: ePrints to digitally publish research papers, grid computing portals and workflows, institutional-wide provisioning and authentication systems, and legal protocols for copyright management. QUT also has two widely recognised centres focused on fundamental research into eResearch itself: The OAK LAW project (Open Access to Knowledge) which focuses upon legal issues relating eResearch and the Microsoft QUT eResearch Centre whose goal is to accelerate scientific research discovery, through new smart software. In order to better harness all of these resources and improve research outcomes, the university recently established a project to investigate how it might better organise the support of eResearch. This presentation will outline the project outcomes, which include a flexible and sustainable eResearch support service model addressing short and longer term research needs, identification of resource requirements required to establish and sustain the service, and the development of research data management policies and implementation plans.

Queensland University of Technology (QUT) is a multidisciplinary university in Brisbane, Queensland, Australia, and has 40,000 students and 1,700 researchers. Notable eResearch infrastructure includes the QUT ePrints repository, Microsoft QUT Research Centre, the OAK (Open Access to Knowledge) Law Project, Cambia and leading research institutes. ---------- The Australian Government, via the Australian National Data Service (ANDS), is funding institutions to identify and describe their research datasets, to develop and populate data repositories and collaborative infrastructure, and to seed the Australian Research Data Commons. QUT is currently broadening its range of research support services, including those to support the management of research data, in recognition of the value of these datasets as products of the research process, and in order to maximize the potential for reuse. QUT is integrating Library and High Performance Computing (HPC) services to achieve its research support goals. ---------- The Library and HPC released an online survey using Key Survey to 1,700 researchers in September 2009. A comprehensive range of eResearch practices and skills was presented for response, and grouped into areas of scholarly communication and open access publishing, using collaborative technologies, data management, data collection and management, computation and visualization tools. Researchers were asked to rate their skill level on each practice. 254 responses were received over two weeks. Eight focus groups were also held with 35 higher degree research (HDR) students and staff to provide additional qualitative feedback. A similar survey was released to 100 support staff and 73 responses were received.---------- Preliminary results from the researcher survey and focus groups indicate a gap between current eResearch practices, and the potential for researchers to engage in eResearch practices. Researchers are more likely to seek advice from their peers, than from support staff. HDR students are more positive about eResearch practices and are more willing to learn new ways of conducting research. An account of the survey methodology, the results obtained, and proposed strategies to embed eResearch practices and skills across and within the research disciplines will be provided.

This research provides a systematic and theoretical analysis of the digital challenges to the established exclusive regime of the economic rights enjoyed by authors (and related rightholders) under the law of copyright. Accordingly, this research has developed a relational theory of authorship and a relational approach to copyright, contending that the regulatory emphasis of copyright law should focus on the facilitation of the dynamic relations between the culture, the creators, the future creators, the users and the public, rather than the allocation of resources in a static world. In this networked digital world, the creative works and contents have become increasingly vital for people to engage in creativity and cultural innovation, and for the evolution of the economy. Hence, it is argued that today copyright owners, as content holders, have certain obligations to make their works accessible and available to the public under fair conditions. This research sets forward a number of recommendations for the reform of the current copyright system.

Intellectual property is crucial to the promotion of innovation. It provides an incentive to innovate as well as security for investment in innovation. The industries of the 21st century-information technology, biotechnology, pharmaceuticals, communications, education and entertainment – are all knowledge-based. The WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (the TRIPS Agreement), adopted in 1994 at the conclusion of the Uruguay Round of trade negotiations, requires all WTO member countries to provide for the protection and enforcement of intellectual property rights. Having forged a link for the first time between intellectual property rights and the international trading system, the adoption of TRIPS means that any country that aims to participate fully in the global economy needs to understand the role of intellectual property and align its intellectual property laws and practices with the international minimum standards prescribed by TRIPS. However, for developing and least-developed countries, the implementation of intellectual property systems and enforcement mechanisms raises questions and challenges. Does recognition and enforcement of intellectual property serve their development needs and objectives? Does TRIPS encourage or hinder the transfer of technologies to developing and least-developed countries, particularly those that meet urgent needs in areas such as public health, food security, water and energy? What is the effect of TRIPS on developing countries’ access to knowledge and information? Is there scope for flexibility in implementation of TRIPS in pursuit of development strategies?

Mobile technologies are enabling access to information in diverse environ.ments, and are exposing a wider group of individuals to said technology. Therefore, this paper proposes that a wider view of user relations than is usually considered in information systems research is required. Specifically, we examine the potential effects of emerging mobile technologies on end-­‐user relations with a focus on the ‘secondary user’, those who are not intended to interact directly with the technology but are intended consumers of the technology’s output. For illustration, we draw on a study of a U.K. regional Fire and Rescue Service and deconstruct mobile technology use at Fire Service incidents. Our findings provide insights, which suggest that, because of the nature of mobile technologies and their context of use, secondary user relations in such emerging mobile environments are important and need further exploration.

This thesis introduces a theory of intellectual property (IP) law informed by Islamic Shari'a. The sources and objectives of Islamic Shari'a support the theoretical framework underpinning IP laws. However, they strongly emphasise the importance of development goals in intellectual property policy making. This thesis argues that an optimal IP system from an Islamic perspective shall not overprotect IP holders but should instead endeavor to empower people to access knowledge resources to enhance access to education, public health and economic opportunities. Taking Libya as a case study, this thesis makes recommendations for the improvement of IP law that have important broader implications for developing countries.

This essay provides a critical assessment of the Fair Use Project based at the Stanford Center for Internet and Society. In evaluating the efficacy of the Fair Use Project, it is worthwhile considering the litigation that the group has been involved in, and evaluating its performance. Part 1 outlines the history of the Stanford Center for Internet and Society, and the aims and objectives of the Fair Use Project. Part 2 considers the litigation in Shloss v. Sweeney over a biography concerning Lucia Joyce, the daughter of the avant-garde literary great, James Joyce. Part 3 examines the dispute over the Harry Potter Lexicon. Part 4 looks at the controversy over the Shepard Fairey poster of President Barack Obama, and the resulting debate with Associated Press. Part 5 of the essay considers the intervention of the Fair Use Project as an amicus curiae in the ‘Column case’. Part 6 explores the participation of the Fair Use Project as an amicus curiae in the litigation over 60 Years Later, an unauthorised literary sequel to J.D. Salinger’s The Catcher in the Rye. Part 7 of the essay investigates the role of the Fair Use project in disputes over copyright law and musical works. Part 8 investigates the role of the Fair Use Project as an advocate in disputes over copyright law, fair use, documentary films, and internet videos. The conclusion has main three arguments. First, it contends that Australia should establish a Fair Use Project to support creative artists in litigation over copyright exceptions. Second, it maintains that Australia should adopt a flexible, open-ended defence of fair use, and draw upon the rich jurisprudence in the United States on the fair use doctrine. Finally, this paper argues that support should be given at an international level to the proposal for a Treaty on Access to Knowledge.

The Trans-Pacific Partnership (TPP) is a highly secretive trade agreement being negotiated between the US and eleven Pacific Rim countries, including Australia. Having obtained a fast-track authority from the United States Congress, US President Barack Obama is keen to finalise the deal. However, he was unable to achieve a resolution of the deal at recent talks in Hawaii on the TPP. A number of chapters of the TPP will affect the creative artists, cultural industries and internet freedom — including the intellectual property chapter, the investment chapter, and the electronic commerce chapter. Legacy copyright industries have pushed for longer and stronger copyright protection throughout the Pacific Rim. In the wake of the Hawaii talks, Knowledge Ecology International leaked the latest version of the intellectual property chapter of the TPP. Jamie Love of Knowledge Ecology International commented upon the leaked text about copyright law: ‘In many sections of the text, the TPP would change global norms, restrict access to knowledge, create significant financial risks for persons using and sharing information, and, in some cases, impose new costs on persons producing new knowledge goods.’ The recent leaked text reveals a philosophical debate about the nature of intellectual property law. There are mixed messages in respect of the treatment of the public domain under copyright law. In one part of the agreement on internet service providers, there is text that says that the parties recognise the need for ‘promoting innovation and creativity,’ ‘facilitating the diffusion of information, knowledge, technology, culture, and the arts’, and ‘foster competition and open and efficient markets.’ A number of countries suggested ‘acknowledging the importance of the public domain.’ The United States and Japan opposed the recognition of the public domain in this text.

Taking an interdisciplinary approach unmatched by any other book on this topic, this thoughtful Handbook considers the international struggle to provide for proper and just protection of Indigenous intellectual property (IP). In light of the United Nations Declaration on the Rights of Indigenous Peoples 2007, expert contributors assess the legal and policy controversies over Indigenous knowledge in the fields of international law, copyright law, trademark law, patent law, trade secrets law, and cultural heritage. The overarching discussion examines national developments in Indigenous IP in the United States, Canada, South Africa, the European Union, Australia, New Zealand, and Indonesia. The Handbook provides a comprehensive overview of the historical origins of conflict over Indigenous knowledge, and examines new challenges to Indigenous IP from emerging developments in information technology, biotechnology, and climate change. Practitioners and scholars in the field of IP will learn a great deal from this Handbook about the issues and challenges that surround just protection of a variety of forms of IP for Indigenous communities.
