Dramaturgy as a Model for Geographically Displaced Collaborations: Views from Within and Views from Without

The network is currently not only widely used for performative actions, but also extensively theorised. However, the artistic strategies in networked environments and the ways in which these new performance practices and cultural contexts can give rise to new design approaches have not been equally explored. This article therefore investigates the notion of dramaturgy as it provides a useful framework for addressing design strategies and performative relationships in networked environments. It is argued that dramaturgies suggest a robust method for understanding artistic practices in the network. The author refers to two different viewpoints that emerge in networked practice, which are entitled ;views from within' and ;views from without'. The article gives a brief overview of the history and the theories of the network. It then looks at the histories of dramaturgies in order to better understand artistic strategies, and in order to enhance collaborative work in network performance environments.

Crossing borders through cyberspace: a discussion of a social work education electronic exchange pilot project across the Atlantic

This article discusses a trial electronic exchange project developed between social work education departments in the Republic of Ireland and the USA. It outlines the contemporary significance and challenges of integrating global content into national social work curricula, which are often strongly tied to statutory or accreditation requirements. The mechanics of the exchange are explained and critiqued in detail. An illustrative example of how the transnational students discussed two questions is analyzed. The article finds that an international electronic exchange has great potential to make global social work real to students by allowing them to cross borders through cyberspace, however it requires careful planning and attention to cultural and educational system differences.

Social Exchange at Work and Emotional Exhaustion: The Role of Personality

Unbalanced social-exchange processes at work have been linked to emotional exhaustion. In addition to organizational factors, individual differences are important determinants of reciprocity perceptions. This study explored whether broad and narrow personality traits were associated with perceived lack of reciprocity (organizational and interpersonal levels), and whether personality moderated the relationship between reciprocity and emotional exhaustion, in a sample of 322 civil servants. Extraversion, agreeableness, emotional stability, internal locus of control, and Type A behavior predicted reciprocity. The relationship between perceived lack of reciprocity with the organization and emotional exhaustion was stronger for individuals reporting lower negative affect or higher extraversion. These findings highlight the importance of personality for understanding perceived reciprocity at work and its impact on emotional exhaustion.

Knowledge Exchange, Spatial Analysis & Healthy Urban Environments (KESUE): Project Report

The Knowledge Exchange, Spatial Analysis and Healthy Urban Environments (KESUE) project has extended work previously undertaken by a QUB team of inter-disciplinary researchers engaged with the Physical Activity in the Regeneration of Connswater (PARC) project (Tully et al, 2013). The PARC project focussed on parts of East Belfast to assess the health impact of the Connswater Community Greenway. The KESUE project has aimed to extend some of the tools used initially in East Belfast so that they have data coverage of all of Belfast and Derry-Londonderry. The purpose of this has been to enable the development of evidence and policy tools that link features of the built environment with physical activity in these two cities. The project has used this data to help shape policy decisions in areas such as physical activity, park management, public transport and planning.

Working with a range of local partners who part-funded the project (City Councils in Belfast and Derry-Londonderry, Public Health Agency, Belfast Healthy Cities and Department of Regional Development), this project has mapped all the footpaths in the two cities (covering 37% of the NI population) and employed this to develop evidence used in strategies related to healthy urban planning. Using Geographic Information Systems (GIS), the footpath network has been used as a basis for a wide range of policy-relevant analyses including pedestrian accessibility to public facilities, site options for new infrastructure and assessing how vulnerable groups can access services such as pharmacies. Key outputs have been Accessibility Atlases and maps showing how walkability of the built environment varies across the two cities.

In addition to generating this useful data, the project included intense engagement with potential users of the research, which has led to its continued uptake in a number of policies and strategies, creating a virtuous circle of research, implementation and feedback. The project has proved so valuable to Belfast City Council that they have now taken on one of the researchers to continue the work in-house.

Experimental investigation of the processes determining x-ray emission intensities from charge-exchange collisions

Absolute cross sections have been measured for single and double charge exchange and x-ray line emission for highly charged ions of C, N, 0, and Ne colliding with He, H-2 CO2, and H2O at collisions energies of 7q keV. Present results of charge exchange in He and H-2 compare favorably with previous results. For CO2 and H2O, where prior work is scarce, the classical overbarrier model is found to overestimate results by up to a factor of 3. An analysis of the relative intensities of the observed Lyman x-ray transitions indicates that capture into l states is not statistical, as collision velocities are insufficient to populate the highest angular-momentum states. The importance of autoionization following multiple capture is highlighted, and enhanced radiative stabilization following double capture is observed and compared to other studies. Present results are also discussed in terms of mechanisms likely to generate x-ray emission in comets.

Mapping the Governance Reform of Welfare to Work in Britain under New Labour

This article draws on Newman's (2001, 2007) typology of the modernization of governance under New Labor, to examine the development of British welfare to work administration. Concentrating on the delivery of active labor market policy, the article suggests network forms of governance occupy a marginal role in welfare to work delivery. Managerialist and hierarchical forms of governance dominate administration of activation policy. In accordance with UK tradition, a national centralized, top down system exercises control of social security and employment services administration, but increasingly seeks to realize its goals through a market system of delivery.

Solving exchange rate puzzles with neither sticky prices nor trade costs

We present a simple framework in which both the exchange rate disconnect and forward bias puzzles are simultaneously resolved. The flexible-price two-country monetary model is extended to include a consumption externality with habit persistence. Habitpersistence is modeled using Campbell Cochrane preferences with ‘deep’ habits along the lines of the work of Ravn, Schmitt-Grohe and Uribe. By deep habits, we mean habits defined over goods rather than countries. The model is simulated using the artificial economy methodology. It offers a neo-classical explanation of the Meese–Rogoff puzzle and mimics the failure of fundamentals to explain nominal exchange rates in a linear setting. Finally, the model naturally generates the negative slope in the standard forward market regression.

Dramaturgy in the Network

This article addresses challenges and opportunities posed by the design and production of network performance from the point of view of collaborative creative work. It examines strategies that, while referring to the network as a new medium for performance, make use of concepts from dramaturgy to better understand the relationships between artists, audiences and media. The author characterises three distinct models for dramaturgy, particularly from the point of view of collaboration, authorship, presence and environment.

Identifying Critical Financial Networks of the DJIA: Toward a Network-Based Index

The purpose of this article is twofold. First, we introduce a novel definition of financial networks obtained from time series data from the stock market. Second, we demonstrate that these networks can be used as an index with the property to reflect critical states of the market, respectively, crashes sufficiently. Our work aims to advocate a network-based analysis in the context of the stock market, because such a collective phenomenon can not only be economically described by networks but also analyzed as demonstrated in this article.

Drivers of Supply Network Governance: An Explorative Study of the Dutch Chemical Industry.

The authors identify a number of drivers of supply network governance, a widely appraised governance form aimed at reaping the benefits of both vertical integration and market exchange. Case studies conducted in the Dutch chemical industry are used to explore these drivers. The findings identify interdependence of organizational activities and asset-specific investments as the key drivers of supply network governance in the chemical industry. Firms enjoy relational rents and tend to share knowledge in supply network relationships, however these factors seem to strengthen supply network relationships rather than create them.

An efficient neural network approach for nanoscale FinFET modelling and circuit simulation

The present paper demonstrates the suitability of artificial neural network (ANN) for modelling of a FinFET in nano-circuit simulation. The FinFET used in this work is designed using careful engineering of source-drain extension, which simultaneously improves maximum frequency of oscillation f(max) because of lower gate to drain capacitance, and intrinsic gain A(V0) = g(m)/g(ds), due to lower output conductance g(ds). The framework for the ANN-based FinFET model is a common source equivalent circuit, where the dependence of intrinsic capacitances, resistances and dc drain current I-d on drain-source V-ds and gate-source V-gs is derived by a simple two-layered neural network architecture. All extrinsic components of the FinFET model are treated as bias independent. The model was implemented in a circuit simulator and verified by its ability to generate accurate response to excitations not used during training. The model was used to design a low-noise amplifier. At low power (J(ds) similar to 10 mu A/mu m) improvement was observed in both third-order-intercept IIP3 (similar to 10 dBm) and intrinsic gain A(V0) (similar to 20 dB), compared to a comparable bulk MOSFET with similar effective channel length. This is attributed to higher ratio of first-order to third-order derivative of I-d with respect to gate voltage and lower g(ds), in FinFET compared to bulk MOSFET.

Strategies for critical reflection in international contexts for social work students

International contexts provide social work students with the opportunity to develop knowledge of international social work, global citizenship and cultural competency. While these contexts are powerful sites of learning, there is a need to ensure that this occurs within a critical framework. The paradigm of critical reflection is used to facilitate this and has been popular in international programs. In this article, we develop this further by describing critically-reflective techniques and providing examples used in a pilot exchange program between a social work school in the UK and in India. The potential implications of these strategies for social work education are discussed. © The Author(s) 2012
