This research adds to a body of work exploring the role of Social Network Analysis (SNA) in the study of both relational and structural characteristics of supply chain networks. Two contrasting network cases (food enterprises and digital-based enterprises) are chosen in order to elicit structural differences in business networks subject to divergences in local embeddedness and the relative materiality of the goods and services produced. Our analysis and findings draw out differences in network structure as evidenced by metrics of network centralization and cohesion, the presence of components and other sub-groupings, and the position of central actors. We relate these structural features both to the nature of the networks and to the (qualitative) experiences of the actors themselves. We find, in particular, the role of customers as co-creators of knowledge (for the Food network), the central role of infrastructure and services (for the Digital network), the importance of ICT as a source of codified knowledge inputs, along with the continuing importance of geographical proximity for the development and transfer of tacit knowledge and for incremental learning.

This thesis explores whether a specific group of large EU law firms exhibited multiple common behaviours regarding their EU geographies between 1998 and 2009. These potentially common behaviours included their preferences for trading in certain EU locations, their usage of law firm alliances, and the specific reasons why they opened or closed EU branch offices. If my hypothesis is confirmed, this may indicate that certain aspects of large law firm geography are predictable – a finding potentially of interest to various stakeholders globally, including legal regulators, academics and law firms. In testing my hypothesis, I have drawn on research conducted by the Globalization and World Cities (GaWC) Research Network to assist me. Between 1999 and 2010, the GaWC published seven research papers exploring the geographies of large US and UK law firms. Several of the GaWC’s observations arising from these studies were evidence-based; others were speculative – including a novel approach for explaining legal practice branch office change, not adopted in research conducted previously or subsequently. By distilling the GaWC’s key observations these papers into a series of “sub-hypotheses”, I been able to test whether the geographical behaviours of my novel cohort of large EU law firms reflect those suggested by the GaWC. The more the GaWC’s suggested behaviours are observed among my cohort, the more my hypothesis will be supported. In conducting this exercise, I will additionally evaluate the extent to which the GaWC’s research has aided our understanding of large EU law firm geography. Ultimately, my findings broadly support most of the GaWC’s observations, notwithstanding our cohort differences and the speculative nature of several of the GaWC’s propositions. My investigation has also allowed me to refine several of the GaWC’s observations regarding commonly-observable large law firm geographical behaviours, while also addressing a key omission from the group’s research output.

Computer games have now been around for over three decades and the term serious games has been attributed to the use of computer games that are thought to have educational value. Game-based learning (GBL) has been applied in a number of different fields such as medicine, languages and software engineering. Furthermore, serious games can be a very effective as an instructional tool and can assist learning by providing an alternative way of presenting instructions and content on a supplementary level, and can promote student motivation and interest in subject matter resulting in enhanced learning effectiveness. REVLAW (Real and Virtual Reality Law) is a research project that the departments of Law and Computer Science of Westminster University have proposed as a new framework in which law students can explore a real case scenario using Virtual Reality (VR) technology to discover important pieces of evidence from a real-given scenario and make up their mind over the crime case if this is a murder or not. REVLAW integrates the immersion into VR as the perception of being physically present in a non-physical world. The paper presents the prototype framework and the mechanics used to make students focus on the crime case and make the best use of this immersive learning approach.

Biodiversity loss is one of the most significant drivers of ecosystem change and is projected to continue at a rapid rate. While protected areas, such as national parks, are seen as important refuges for biodiversity, their effectiveness in stemming biodiversity decline has been questioned. Public agencies have a critical role in the governance of many such areas, but there are tensions between the need for these agencies to be more “adaptive” and their current operating environment. Our aim is to analyze how institutions enable or constrain capacity to conserve biodiversity in a globally significant cross-border network of protected areas, the Australian Alps. Using a novel conceptual framework for diagnosing biodiversity institutions, our research examined institutional adaptive capacity and more general capacity for conserving biodiversity. Several intertwined issues limit public agencies’ capacity to fulfill their conservation responsibilities. Narrowly defined accountability measures constrain adaptive capacity and divert attention away from addressing key biodiversity outcomes. Implications for learning were also evident, with protected area agencies demonstrating successful learning for on-ground issues but less success in applying this learning to deeper policy change. Poor capacity to buffer political and community influences in managing significant cross-border drivers of biodiversity decline signals poor fit with the institutional context and has implications for functional fit. While cooperative federalism provides potential benefits for buffering through diversity, it also means protected area agencies have restricted authority to address cross-border threats. Restrictions on staff authority and discretion, as public servants, have further implications for deploying capacity. This analysis, particularly the possibility of fostering “ambidexterity”—creatively responding to political pressures in a way that also achieves a desirable outcome for biodiversity conservation—is one promising way of building capacity to buffer both political influences and ecological pressures. The findings and the supporting analysis provide insight into how institutional capacity to conserve biodiversity can be enhanced in protected areas in Australia and elsewhere, especially those governed by public agencies and/or multiple organizations and across jurisdictions.

The International Long-Term Ecological Research (ILTER) network comprises > 600 scientific groups conducting site-based research within 40 countries. Its mission includes improving the understanding of global ecosystems and informs solutions to current and future environmental problems at the global scales. The ILTER network covers a wide range of social-ecological conditions and is aligned with the Programme on Ecosystem Change and Society (PECS) goals and approach. Our aim is to examine and develop the conceptual basis for proposed collaboration between ILTER and PECS. We describe how a coordinated effort of several contrasting LTER site-based research groups contributes to the understanding of how policies and technologies drive either toward or away from the sustainable delivery of ecosystem services. This effort is based on three tenets: transdisciplinary research; cross-scale interactions and subsequent dynamics; and an ecological stewardship orientation. The overarching goal is to design management practices taking into account trade-offs between using and conserving ecosystems toward more sustainable solutions. To that end, we propose a conceptual approach linking ecosystem integrity, ecosystem services, and stakeholder well-being, and as a way to analyze trade-offs among ecosystem services inherent in diverse management options. We also outline our methodological approach that includes: (i) monitoring and synthesis activities following spatial and temporal trends and changes on each site and by documenting cross-scale interactions; (ii) developing analytical tools for integration; (iii) promoting trans-site comparison; and (iv) developing conceptual tools to design adequate policies and management interventions to deal with trade-offs. Finally, we highlight the heterogeneity in the social-ecological setting encountered in a subset of 15 ILTER sites. These study cases are diverse enough to provide a broad cross-section of contrasting ecosystems with different policy and management drivers of ecosystem conversion; distinct trends of biodiversity change; different stakeholders’ preferences for ecosystem services; and diverse components of well-being issues.

This paper explores the extent to which latest developments in the Technical and Vocational Education and Training System in South Africa respond to key principles espoused for a developmental, democratic and inclusionary ideal. The White Paper for post school education and training approved by Cabinet in November, 2013 is referred to by the Minister as the “definitive statement of the governments vision for the post school system” and as such represents a crucial strategy document intended to chart the TVET direction to 2030. Using key theoretical constructs from development theory, this paper provides an assessment of the TVET strategy contained is the paper and explores the extent to which it does respond to the agenda defined by the promise. It is argued that the challenges outlined are not yet able to provide the blueprint for a TVET transformative vision. It is concluded that while the development rhetoric contained in the paper is plausible, the creative tinkering of the system is unlikely to lead to the radical revisioning necessary for a truly transformative TVET system. The underlying assumptions regarding purpose, impact and outcome will need to be carefully reconsidered if the system is to be responsive to the promises of the democratic developmental ideal to which the government is committed.

The Green Deal (GD) was launched in 2013 by the UK Government as a market-led scheme to encourage uptake of energy efficiency measures in the UK and create green sector jobs. The scheme closed in July 2015 after 30 months due to government concerns over low uptake and industry standards but additional factors potentially contributed to its failure such as poor scheme design and lack of understanding of the customer and supply chain journey. We explore the role of key delivery agents of GD services, specifically SMEs, and we use the LoCal-Net project as a case study to examine the use of networks to identify and reduce barriers to SME market engagement. We find that SMEs experienced multiple barriers to interaction with the GD such as lack of access to information, training, and confusion over delivery of the scheme but benefited from interaction with the network to access information, improve understanding of the scheme, increasing networking opportunities and forming new business models and partnerships to reduce risk. The importance of SMEs as delivery agents and their role in the design of market-led schemes such as the GD are discussed with recommendations for improving SME engagement in green sector initiatives.

The Internet of things (IoT) is still in its infancy and has attracted much interest in many industrial sectors including medical fields, logistics tracking, smart cities and automobiles. However, as a paradigm, it is susceptible to a range of significant intrusion threats. This paper presents a threat analysis of the IoT and uses an Artificial Neural Network (ANN) to combat these threats. A multi-level perceptron, a type of supervised ANN, is trained using internet packet traces, then is assessed on its ability to thwart Distributed Denial of Service (DDoS/DoS) attacks. This paper focuses on the classification of normal and threat patterns on an IoT Network. The ANN procedure is validated against a simulated IoT network. The experimental results demonstrate 99.4% accuracy and can successfully detect various DDoS/DoS attacks.

Since early 80s the Council of Europe has taken a great approach to teaching and learning of languages by encouraging plurilingual practices instead of multilingual practices, being these understood as the coexistence of several languages within a given society. In this context, we believe that once one learns many languages, one values one's native language, allowing one to understand it more clearly and to communicate with others on an equal footing and, more importantly, one also learns about other cultures. This is an issue of great importance in order to value and respect one's own and other cultures in the context of European integration. Considering this, in this article, we present two linked projects: a) the “PrimaLang” project, related teaching practices multilingual promoting critical cultural awarenessl in the 1st cycle of Portuguese Primary School System; b) the “Plurilingual” project, which refers to the design of a coursebook which stimulates the development of a plurilingual competence in the 1st cycle of Portuguese Primary School System. At the same time, we analyze some materials made by students and teachers in the projects to better understand their contribution under the InterNetwork Comenius Project
