Amplifying applied game development and uptake

The established (digital) leisure game industry is historically one dominated by large international hardware vendors (e.g. Sony, Microsoft and Nintendo), major publishers and supported by a complex network of development studios, distributors and retailers. New modes of digital distribution and development practice are challenging this business model and the leisure games industry landscape is one experiencing rapid change. The established (digital) leisure games industry, at least anecdotally, appears reluctant to participate actively in the applied games sector (Stewart et al., 2013). There are a number of potential explanations as to why this may indeed be the case including ; A concentration on large-scale consolidation of their (proprietary) platforms, content, entertainment brand and credibility which arguably could be weakened by association with the conflicting notion of purposefulness (in applied games) in market niches without clear business models or quantifiable returns on investment. In contrast, the applied games industry exhibits the characteristics of an emerging, immature industry namely: weak interconnectedness, limited knowledge exchange, an absence of harmonising standards, limited specialisations, limited division of labour and arguably insufficient evidence of the products efficacies (Stewart et al., 2013; Garcia Sanchez, 2013) and could, arguably, be characterised as a dysfunctional market. To test these assertions the Realising an Applied Gaming Ecosystem (RAGE) project will develop a number of self contained gaming assets to be actively employed in the creation of a number of applied games to be implemented and evaluated as regional pilots across a variety of European educational, training and vocational contexts. RAGE is a European Commission Horizon 2020 project with twenty (pan European) partners from industry, research and education with the aim of developing, transforming and enriching advanced technologies from the leisure games industry into self-contained gaming assets (i.e. solutions showing economic value potential) that could support a variety of stakeholders including teachers, students, and, significantly, game studios interested in developing applied games. RAGE will provide these assets together with a large quantity of high-quality knowledge resources through a self-sustainable Ecosystem, a social space that connects research, the gaming industries, intermediaries, education providers, policy makers and end-users in order to stimulate the development and application of applied games in educational, training and vocational contexts. The authors identify barriers (real and perceived) and opportunities facing stakeholders in engaging, exploring new emergent business models ,developing, establishing and sustaining an applied gaming eco system in Europe.

Kit positive cells in the guinea pig bladder.

PURPOSE: We describe the presence of interstitial cells of Cajal (ICC) throughout the wall of the guinea pig bladder. MATERIALS AND METHODS: Bladders obtained from male guinea pigs were prepared for immunohistochemical investigations using various primary antibodies, including the specific ICC marker c-kit (Gibco BRL, Grand Island, New York). Enzymatically dispersed cells with a branched morphology were identified as ICC using anti-c-kit. They were loaded with fluo-4acetoxymethyl (Molecular Probes, Eugene, Oregon) and studied using confocal laser scanning microscopy. RESULTS: Anti-c-kit labeling demonstrated that ICC were oriented in parallel with the smooth muscle bundles that run diagonally throughout the bladder. Double labeling with anti-smooth muscle myosin (Sigma Chemical Co., St. Louis, Missouri) revealed that ICC were located on the boundary of smooth muscle bundles. When anti-c-kit was used in combination with the general neuronal antibody protein gene product 9.5 (Ultraclone Ltd., Isle of Wight, United Kingdom) or anti-neuronal nitric oxide synthase, it was noted that there was a close association between nerves and ICC. Enzymatic dissociation of cells from tissue pieces yielded a heterogeneous population of cells containing typical spindle-shaped smooth muscle cells and branched cells resembling ICC from other preparations. The latter could be identified immunohistochemically as ICC using anti-c-kit, whereas the majority of spindle-shaped cells were not Kit positive. Branched cells responded to the application of carbachol by firing Ca2+ waves and they were often spontaneously active. CONCLUSIONS: ICC are located on the boundary of smooth muscle bundles in the guinea pig bladder. They fire Ca2+ waves in response to cholinergic stimulation and can be spontaneously active, suggesting that they could act as pacemakers or intermediaries in the transmission of nerve signals to smooth muscle cells.

Cell-collagen interactions: the use of peptide Toolkits to investigate collagen-receptor interactions

Fibrillar collagens provide the most fundamental platform in the vertebrate organism for the attachment of cells and matrix molecules. we have identified specific sites in collagens to which cells can attach, either directly or through protein intermediaries. Using Toolkits of triple-helical peptides, each peptide comprising 27 residues of collagen primary sequence and overlapping with its neighbours by nine amino acids, we have mapped the binding of receptors and other proteins on to collagens II or III. Integrin alpha 2 beta 1 binds to several GXX'GER motifs within the collagens, the affinities of which differ sufficiently to control cell adhesion and migration independently of the cellular regulation of the integrin. The platelet receptor, Gp (glycoprotein) VI binds well to GPO (where 0 is hydroxyproline)-containing model peptides, but to very few Toolkit peptides, suggesting that sequence in addition to GPO triplets is important in defining GpVI binding. The Toolkits have been applied to the plasma protein vWF (von Willebrand factor), which binds to only a single sequence, identified by truncation and amino acid substitution within Toolkit peptides, as GXRGQOGVMGFO in collagens II and III. Intriguingly, the receptor tyrosine kinase, DDR2 (discoidin domain receptor 2) recognizes three sites in collagen II, including its vWF-binding site, although the amino acids that support the interaction differ slightly within this motif. Furthermore, the secreted protein BM-40 (basement membrane protein 40) also binds well to this same region. Thus the availability of extracellular collagen-binding proteins may be important in regulating and facilitating direct collagen-receptor interaction.

New Financial Elites, or Financial Dualism in Historical perspective? An Extended Reply to Folkman, Froud, Johal and Williams

This paper challenges the recent suggestion that a new financial elite has evolved which is able to capture substantial profit shares for itself. Specifically, it questions the assumption that new groups of financial intermediaries have increased in significance primarily because there is evidence that various types of financial speculators have played a similarly extensive role at several junctures of economic development. The paper then develops the alternative hypothesis that, rather than being a recent development, the rise of these financial intermediaries is a cyclical phenomenon which is linked to specific regimes of capital accumulation. The hypothesis is underpinned by historical data from the US National Income and Product Accounts for the period from 1930 to 2000, which suggest that the activities of `mainstream' financial intermediaries have been accompanied by the frequently countercyclical activities of a `speculative' sector of security and commodity brokers. Based on the combination of this qualitative and quantitative evidence, the paper concludes that the rise of a speculative financial sector is a potentially recurrent phenomenon which is linked to periods of economic restructuring and turmoil.

Developing dance music from the song tradition

This paper takes an historical look at the development of now popular Irish dance tunes which originated in or passed through the song tradition. It discusses the role of what I have termed ‘intermediaries’ which bridge the gap between the song and dance music traditions, allowing repertoire to flow between these two tributary streams of the modern tradition. I will discuss the under-investigated practice of lilting, which I will argue has acted as an important intermediary between the dance and song traditions, particularly in the eighteenth century. before going on to discuss some examples of songs and dance tunes which have a more complex relationship.

The rise of the digital citizen-stakeholder: rebalancing multistakeholder governance

The principle feature in the evolution of the internet has been its ever growing reach to include old and young, rich and poor. The internet’s ever encroaching presence has transported it from our desktop to our pocket and into our glasses. This is illustrated in the Internet Society Questionnaire on Multistakeholder Governance, which found the main factors affecting change in the Internet governance landscape were more users online from more countries and the influence of the internet over daily life. The omnipresence of the internet is self- perpetuating; its usefulness grows with every new user and every new piece of data uploaded. The advent of social media and the creation of a virtual presence for each of us, even when we are not physically present or ‘logged on’, means we are fast approaching the point where we are all connected, to everyone else, all the time. We have moved far beyond the point where governments can claim to represent our views which evolve constantly rather than being measured in electoral cycles.
The shift, which has seen citizens as creators of content rather than consumers of it, has undermined the centralist view of democracy and created an environment of wiki democracy or crowd sourced democracy. This is at the heart of what is generally known as Web 2.0, and widely considered to be a positive, democratising force. However, we argue, there are worrying elements here too. Government does not always deliver on the promise of the networked society as it involves citizens and others in the process of government. Also a number of key internet companies have emerged as powerful intermediaries harnessing the efforts of the many, and re- using and re-selling the products and data of content providers in the Web 2.0 environment. A discourse about openness and transparency has been offered as a democratising rationale but much of this masks an uneven relationship where the value of online activity flows not to the creators of content but to those who own the channels of communication and the metadata that they produce.
In this context the state is just one stakeholder in the mix of influencers and opinion formers impacting on our behaviours, and indeed our ideas of what is public. The question of what it means to create or own something, and how all these new relationships to be ordered and governed are subject to fundamental change. While government can often appear slow, unwieldy and even irrelevant in much of this context, there remains a need for some sort of political control to deal with the challenges that technology creates but cannot by itself control. In order for the internet to continue to evolve successfully both technically and socially it is critical that the multistakeholder nature of internet governance be understood and acknowledged, and perhaps to an extent, re- balanced. Stakeholders can no longer be classified in the broad headings of government, private sector and civil society, and their roles seen as some sort of benign and open co-production. Each user of the internet has a stake in its efficacy and each by their presence and participation is contributing to the experience, positive or negative of other users as well as to the commercial success or otherwise of various online service providers. However stakeholders have neither an equal role nor an equal share. The unequal relationship between the providers of content and those who simple package up and transmit that content - while harvesting the valuable data thus produced - needs to be addressed. Arguably this suggests a role for government that involves it moving beyond simply celebrating and facilitating the on- going technological revolution. This paper reviews the shifting landscape of stakeholders and their contribution to the efficacy of the internet. It will look to critically evaluate the primacy of the individual as the key stakeholder and their supposed developing empowerment within the ever growing sea of data. It also looks at the role of individuals in wider governance roles. Governments in a number of jurisdictions have sought to engage, consult or empower citizens through technology but in general these attempts have had little appeal. Citizens have been too busy engaging, consulting and empowering each other to pay much attention to what their governments are up to. George Orwell’s view of the future has not come to pass; in fact the internet has insured the opposite scenario has come to pass. There is no big brother but we are all looking over each other’s shoulder all the time, while at the same time a number of big corporations are capturing and selling all this collective endeavour back to us.

Critical Nodes In Directed Networks

Critical nodes—or “middlemen”—have an essential place in both social and economic networks when considering the flow of information and trade. This paper extends the concept of critical nodes to directed networks and in doing so identify strong and weak middlemen.
Node contestability is introduced as a form of competition in networks; a duality between uncontested intermediaries and middlemen is established. The brokerage power of middlemen is formally expressed and a general algorithm is constructed to measure the brokerage power of each node from the networks adjacency matrix. Augmentations of the brokerage power measure are discussed to encapsulate relevant centrality measures. Furthermore, we extend these notions and provide measures of the competitiveness of a network.
We use these concepts to identify and measure middlemen in two empirical socio-economic networks, the elite marriage network of Renaissance Florence and Krackhardt’s advice net- work.

Adaptive utilitarianism, social enterprises and urban regeneration

Social enterprises have been placed at the centre of Big Society politics and an emphasis on the local as a site for experimentation and service delivery. Nationally, this has been supported by legislation in community transfer and procurement, social finance and new intermediaries to strengthen skills and loan readiness. This paper examines the role of social enterprises involved in urban development in Northern Ireland and highlights the multiple ethics, legitimation strategies and modalities that are necessary for sustainable forms of progressive regeneration. The paper concludes by stressing the possibilities of a more independent and reformist social economy and how this offers some practical alternatives to the enthusiasm for neoliberal policies in the local state.

Finance, social economics and community development

The last three decades have seen social enterprises in the United Kingdom pushed to the forefront of welfare delivery, workfare and area-based regeneration. For critics, this is repositioning the sector around a neoliberal politics that privileges marketization, state roll-back and disciplining community groups to become more self-reliant. Successive governments have developed bespoke products, fiscal instruments and intermediaries to enable and extend the social finance market. Such assemblages are critical to roll-out tactics, but they are also necessary and useful for more reformist understandings of economic alterity. The issue is not social finance itself but how it is used, which inevitably entangles social enterprises in a form of legitimation crises between the need to satisfy financial returns and at the same time keep community interests on board. This paper argues that social finance, how it is used, politically domesticated and achieves re-distributional outcomes is a necessary component of counter-hegemonic strategies. Such assemblages are as important to radical community development as they are to neoliberalism and the analysis concludes by highlighting the need to develop a better understanding of finance, the ethics of its use and tactical compromises in scaling it as an alternative to public and private markets.

O livro no jardim-de-infância : um olhar sobre a obra de Luísa Ducla Soares

A literatura para a infância tem sido objecto de discussão, especialmente notocante ao seu estatuto no universo literário, sobretudo a partir dos anos 70 doséculo XX, vindo, assim, a desenvolver-se e a assumir uma crescente importância. Decorrente da evolução do conceito de criança, a literatura para ainfância foi assumindo um lugar proeminente na sua formação,nomeadamente, em idade pré-escolar. A seguir à família, o educador de infância afigura-se como outro dos principais mediadores no encontro dacriança com o livro, tendo, desde aí, uma função influente face à promoção dogosto pela leitura. No entanto, este profissional sente a necessidade de, desdea sua formação inicial, sever dotado de conhecimentos básicos que lhe permitam práticas mais ajustadas e que salvaguardem as necessidades einteresses de leitura das crianças. A presente dissertação tem como principal finalidade aferir a importânciaatribuída à literatura para a infância, com especial destaque na obra de Luísa Ducla Soares, em contexto de jardim-de-infância. Apesar do lugar incontestável desta autora e da sua obra no cânone daliteratura portuguesa para a infância, a crítica literária de que tem sido alvo é ainda exígua. Por essa razão também, procurámos, através de uma análisedas especificidades da sua escrita, da diversidade das temáticas inerentes àssuas histórias e da qualidade estética e literária das suas publicações, reflectirsobre as potencialidades das obras que nos apresenta a referida escritora, pelas quais tem merecido vários prémios e nomeações. ABSTRACT: Literature for early years has been subject of quarrel, especially regarding to itsstatute in the literature universe, mostly since the 70’s of the 20th century, andconsequently came to grow and to assume an increasing importance. As aresult of the evolution of the child concept, literature for early years wasassuming a prominent position in children education, specifically, in preschoolage. After family, the kindergarten teacher figures hisself/herself as another of themain intermediaries in introducingchild to books, having, since then, an influential role endorsing reading’s taste on children. However, this practitionerneeds, since his/her formative years, to be endowed with basic knowledge thatallows him/her more adjusted practices that look after reading’s necessities and interests of children’s interests. The present dissertation’s main purpose is to survey which importance hasliterature for infants, with a special focus on the work of Luísa Ducla Soares, inearly childhood education. Even though her books are unquestionable at ruling literature for infants inPortugal, there hasn’t been that much literary analysis about it. Therefore, welooked, through the particulars aspects of her writing, the diversity of themesthat are inherent to her stories and the artistic and literary value of her publications, to proof the quality of the work presented by the mentioned writer,on behalf of which the author has justified several awards and nominations.

Crowdsourcing innovation: a strategy to leverage enterprise innovation

Innovation is recognized by academics and practitioners as an essential competitive enabler for any company to survive, to remain competitive and to grow. Investments in tasks of R&D have not always brought the expected results. But that doesn't mean that the outcomes would not be useful to other companies of the same business area or even from another area. Thus, there is much knowledge already available in the market that can be helpful to some and profitable to others. So, the ideas and expertise can be found outside a company's boundaries and also exported from within. Information, knowledge, experience, wisdom is already available in the millions of the human beings of this planet, the challenge is to use them through a network to produce new ideas and tips that can be useful to a company with less costs. This was the reason for the emergence of the area of crowdsourcing innovation. Crowdsourcing innovation is a way of using the Web 2.0 tools to generate new ideas through the heterogeneous knowledge available in the global network of individuals highly qualified and with easy access to information and technology. So, a crowdsourcing innovation broker is an organization that mediates the communication and relationship between the seekers - companies that aspire to solve some problem or to take advantage of any business opportunity - with a crowd that is prone to give ideas based on their knowledge, experience and wisdom. This paper makes a literature review on models of open innovation, crowdsourcing innovation, and technology and knowledge intermediaries, and discusses this new phenomenon as a way to leverage the innovation capacity of enterprises. Finally, the paper outlines a research design agendafor explaining crowdsourcing innovation brokering phenomenon, exploiting its players, main functions, value creation process, and knowledge creation in order to define a knowledge metamodel of such intermediaries.

Search-for-yield in Portuguese fixed-income mutual funds and monetary policy

This paper studies the effects of monetary policy on mutual fund risk taking using a sample of Portuguese fixed-income mutual funds in the 2000-2012 period. Firstly I estimate time-varying measures of risk exposure (betas) for the individual funds, for the benchmark portfolio, as well as for a representative equally-weighted portfolio, through 24-month rolling regressions of a two-factor model with two systematic risk factors: interest rate risk (TERM) and default risk (DEF). Next, in the second phase, using the estimated betas, I try to understand what portion of the risk exposure is in excess of the benchmark (active risk) and how it relates to monetary policy proxies (one-month rate, Taylor residual, real rate and first principal component of a cross-section of government yields and rates). Using this methodology, I provide empirical evidence that Portuguese fixed-income mutual funds respond to accommodative monetary policy by significantly increasing exposure, in excess of their benchmarks, to default risk rate and slightly to interest risk rate as well. I also find that the increase in funds’ risk exposure to gain a boost in return (search-for-yield) is more pronounced following the 2007-2009 global financial crisis, indicating that the current historic low interest rates may incentivize excessive risk taking. My results suggest that monetary policy affects the risk appetite of non-bank financial intermediaries.

Is the Basel III Leverage Ratio countercyclical? A study for Portuguese banks

This work analyses how the leverage ratio behaves through the cycle, vis-à-vis other capital ratios. For a sample of the largest Portuguese banks, the Basel III leverage ratio is indeed countercyclical. This result is relevant from a regulatory perspective, since the introduction of a limit on the leverage ratio will function as a restriction in the banks’ balance sheet size, reducing the economic costs associated with the excessive growth of leverage in periods of economic expansion followed by aggressive deleveraging in the downturn. However, one cannot exclude that restrictions on banks’ leverage incentivize its transference to less regulated intermediaries.
