A Belief System's Organization Based on a Computational Model of the Dynamic Context: First Approximation

In this article we present a model of organization of a belief system based on a set of binary recursive functions that characterize the dynamic context that modifies the beliefs. The initial beliefs are modeled by a set of two-bit words that grow, update, and generate other beliefs as the different experiences of the dynamic context appear. Reason is presented as an emergent effect of the experience on the beliefs. The system presents a layered structure that allows a functional organization of the belief system. Our approach seems suitable to model different ways of thinking and to apply to different realistic scenarios such as ideologies.

Implementation Feasibility of a Digital Nervous System for the Construction Industry: For Efficient and Effective Information Management across the Project Lifecycle

The construction industry has long been considered as highly fragmented and non-collaborative industry. This fragmentation sprouted from complex and unstructured traditional coordination processes and information exchanges amongst all parties involved in a construction project. This nature coupled with risk and uncertainty has pushed clients and their supply chain to search for new ways of improving their business process to deliver better quality and high performing product. This research will closely investigate the need to implement a Digital Nervous System (DNS), analogous to a biological nervous system, on the flow and management of digital information across the project lifecycle. This will be through direct examination of the key processes and information produced in a construction project and how a DNS can provide a well-integrated flow of digital information throughout the project lifecycle. This research will also investigate how a DNS can create a tight digital feedback loop that enables the organisation to sense, react and adapt to changing project conditions. A Digital Nervous System is a digital infrastructure that provides a well-integrated flow of digital information to the right part of the organisation at the right time. It provides the organisation with the relevant and up-to-date information it needs, for critical project issues, to aid in near real-time decision-making. Previous literature review and survey questionnaires were used in this research to collect and analyse data about information management problems of the industry – e.g. disruption and discontinuity of digital information flow due to interoperability issues, disintegration/fragmentation of the adopted digital solutions and paper-based transactions. Results analysis revealed efficient and effective information management requires the creation and implementation of a DNS.

Improving the photoactivity of bismuth vanadate thin film photoanodes through doping and surface modification strategies

Currently, one of the most attractive and desirable ways to solve the energy challenge is harvesting energy directly from the sunlight through the so-called artificial photosynthesis. Among the ternary oxides based on earth–abundant metals, bismuth vanadate has recently emerged as a promising photoanode. Herein, BiVO4 thin film photoanodes have been successfully synthesized by a modified metal-organic precursor decomposition method, followed by an annealing treatment. In an attempt to improve the photocatalytic properties of this semiconductor material for photoelectrochemical water oxidation, the electrodes have been modified (i) by doping with La and Ce (by modifying the composition of the BiVO4 precursor solution with the desired concentration of the doping element), and (ii) by surface modification with Au nanoparticles potentiostatically electrodeposited. La and Ce doping at concentrations of 1 and 2 at% in the BiVO4 precursor solution, respectively, enhances significantly the photoelectrocatalytic performance of BiVO4 without introducing important changes in either the material structure or the electrode morphology, according to XRD and SEM characterization. In addition, surface modification of the electrodes with Au nanoparticles further enhances the photocurrent as such metallic nanoparticles act as co-catalysts, promoting charge transfer at the semiconductor/solution interface. The combination of these two complementary ways of modifying the electrodes has resulted in a significant increase in the photoresponse, facilitating their potential application in artificial photosynthesis devices.

Modernist Ecology: Modernism and the Reimagination of Nature

Countering the trend in contemporary ecocriticism to advance realism as an environmentally responsible mode of representation, this essay argues that the anti-realist aesthetics of literary modernism were implicitly “ecological.” In order to make this argument I distinguish between contemporary and modernist ecological culture (both of which I differentiate in turn from ecological science); while the former is concerned primarily with the practical reform characteristic of what we now call “environmentalism,” the latter demanded an all-encompassing reimagination of the relationship between humanity and nature. “Modernist ecology,” as I call it, attempted to envision this change, which would be ontological or metaphysical rather than simply social, through thematically and formally experimental works of art. Its radical vision, suggestive in some ways of today’s “deep” ecology, repudiated modern accounts of nature as a congeries of inert objects to be manipulated by a sovereign subject, and instead foregrounded the chiasmic intertexture of the subject/object relationship. In aesthetic modernism we encounter not “objective” nature, but “nature-being” – a blank substratum beneath the solid contours of what philosopher Kate Soper calls “lay nature” – the revelation of which shatters historical constructions of nature and alone allows for radical alternatives. This essay looks specifically at modernist ecology as it appears in the works of W. B. Yeats, D. H. Lawrence, and Samuel Beckett, detailing their attempts to envision revolutionary new ecologies, but also their struggles with the limited capacity of esoteric modernist art to effect significant ecological change on a collective level.

The future imagined: Exploring fiction as a means of reflecting on today’s Grand Societal Challenges and tomorrow’s options

European science policy (so-called Horizon 2020) is guided by Grand Societal Challenges (GSCs) with the explicit aim of shaping the future. In this paper we propose an innovative approach to the analysis and critique of Europe’s GSCs. The aim is to explore how speculative and creative fiction offer ways of embodying, telling, imagining, and symbolising ‘futures’, that can provide alternative frames and understandings to enrich the grand challenges of the 21st century, and the related rationale and agendas for ERA and H2020. We identify six ways in which filmic and literary representations can be considered creative foresight methods (i.e. through: creative input, detail, warning, reflection, critique, involvement) and can provide alternative perspectives on these central challenges, and warning signals for the science policy they inform. The inquiry involved the selection of 64 novels and movies engaging with notions of the future, produced over the last 150 years. Content analysis based on a standardised matrix of major themes and sub-domains, allows to build a hierarchy of themes and to identify major patterns of long-lasting concerns about humanity’s future. The study highlights how fiction sees oppression, inequality and a range of ethical issues linked to human and nature’s dignity as central to, and inseparable from innovation, technology and science. It concludes identifying warning signals in four major domains, arguing that these signals are compelling, and ought to be heard, not least because elements of such future have already escaped the imaginary world to make part of today’s experience. It identifies areas poorly defined or absent from Europe's science agenda, and argues for the need to increase research into human, social, political and cultural processes involved in techno-science endeavours.

The European Council’s Guidelines for the Area of Freedom, Security and Justice 2020: Subverting the ‘Lisbonisation’ of Justice and Home Affairs? CEPS Essay No. 13, 14 July 2014

In its Conclusions of 26-27 June 2014, the European Council has adopted the new “Strategic Guidelines for Legislative and Operational Planning for the coming years within the EU’s Area of Freedom, Security and Justice (AFSJ)”. These Guidelines reveal a pre-Lisbon Treaty mindset among the EU member states and the Justice and Home Affairs Council. This essay argues that the Guidelines are mainly driven by the interests and agendas of national Ministries of Interior and Justice and are only “strategic” to the extent that they aim at first, re-injecting ‘intergovernmentalism’ or bringing back the old EU Third Pillar ways of working to the new EU institutional setting of the AFSJ and second, at sidelining the EU Charter of Fundamental Rights and rule of law in the AFSJ. The paper argues that the European Council Guidelines seek to prevent the advances in Justice and Home Affairs cooperation as envisaged in the Treaty of Lisbon, particularly its emphasis on supranational democratic, legal and judicial accountability. As a consequence of this move to ‘de-Lisbonise’ JHA cooperation, fundamental rights and rule of law-related initiatives will be neglected and the interest of the individual will be displaced from the centre of gravity in the coming AFSJ 2020 policy agenda.

The Impact of the Collaborative Economy on the Labour Market. CEPS Special Report No. 138, June 2016

The digitalisation of work is creating new ways of intermediating work, with for example platforms intermediating work between individuals online. These so-called online collaborative platforms have the potential to fundamentally change the labour market, but for the moment, with an estimated 100,000 active workers or 0.05% of total employees in the EU, they do not seem to have a large impact on the offline/traditional labour market or the create/destroy impetus. This paper analyses the direct and indirect impact of the collaborative economy on the labour market. The findings, based on a collection of empirical studies, suggest that most workers do not earn their main income through online platforms and they obtain earnings from different types of platforms. Earnings from physical/local services are, in general, substantially higher than virtual services that can potentially be delivered globally. The paper also assesses the conditions, number of hours worked and employment status, compared to the offline labour market, and finds shows large differences across types of workers, platforms, and countries. The emergence of online collaborative platforms poses some challenges and opportunities for policy-makers. On the one hand, they may be challenged to ensure minimum remuneration, fair evaluation, tax declaration and social protection, and reduction of the administrative burden. On the other hand, the new technologies may provide opportunities to (partially) liberate some professional services and activate specific groups at a distance away from the labour market. This paper was commissioned by the European Commission as input into its European Agenda for the Collaborative Economy. This Ag

De-authoring or Authoring?: A plunge into the question of authorship and language in J.M. Coetzee's Foe

J. M. Coetzee's Foe is not only a post-colonial novel, but it is also a re-writing of a classic, and its main themes are language, authorship, power and identity. Moreover, Foe is narrated by a woman, while written by a male, Nobel prize winning South African author. The aim of my tesina is to focus on the question of authorship and the role of language in Foe. Without any claim to be exhaustive, in the first section I will examine some selected extracts of Coetzee's book, in order to provide an analysis of the novel. These quotations will mainly be its metalinguistic parts and will be analysed in the “theory” sections of my work, relying on literary theory and on previous works on the novel. Among others, I will cover themes such as the relationship between speech and writing, the connection between writing, history, and memory, the role of silence and alternative ways of communicating and the relationship between literary authority and truth. These arguments will be the foundation for my second section, in which I will attempt to shed a light on the importance of the novel from a linguistic point of view, but always keeping an eye on the implication that this has on authorship. While it is true that it is less politically-permeated than Coetzee's previous works, Foe is above all a “journey of discovery” in the world of language and authorship. In fact, it becomes a warning for any person immersed in the ocean of language since, while everyone naturally tends to trust speech and writing as the only medium through which one can get closer to the truth, authority never is a synonym of reliability, and language is a system of communication behind which structures of power, misconceptions, lies, and treacherous tides easily hide.

(Table 1) Lithological and organic-geochemical compositions of bottom sediments from the Southwestern Indian Ocean (Mozambique Basin)

Geochemical changes in organic matter of bottom sediments from the Mozambique Basin at the river-sea barrier from the mouths of the Zambezi and Limpopo rivers toward the pelagic zone are discussed. Changes in bitumen, hydrolyzable material, humic acids, amino acids, n-alkanes, and polycyclic aromatic compounds resulting from genetic and diagenetic factors are described. This information is significant for paleoceanology reconstructions and for knowing ways of organic matter transformation into fossil forms.
