Event-related potentials (ERPs) can be elicited by a variety of stimuli and events in diverse conditions. This chapter covers the methodology of analyzing and quantifying ERPs in general. Basic models (additive, phase modulation and resetting, potential asymmetry) that account for the generation of ERPs are discussed. The principles and requirements of ensemble time averaging are presented, along with several univariate and multivariate methods that have been proposed to improve the averaging procedure: wavelet decomposition and denoising, spatial, temporal and spatio-temporal filtering. We emphasize basic concepts of principal component analysis, common spatial pattern, and blind source separation, including independent component analysis. We cover practical questions related to the averaging procedure: overlapping ERPs, correcting inter-sweep latency and amplitude variability, alternative averaging methods (e.g., median), and estimation of ERP onset. Some specific aspects of ERP analysis in the frequency domain are surveyed, along with topographic analysis, statistical testing, and classification methods.

Faecal sludge management is recognized globally as an essential component of city-wide inclusive sanitation. However, a major gap in developing appropriate and adequate management and monitoring for faecal sludge is the ability to understand and predict the characteristics and volumes of accumulated faecal sludge, and correlations to source populations. Since standard methods for sampling and analysing faecal sludge do not currently exist, results are not comparable, the actual variability is not yet fully understood, and the transfer of knowledge and data between different regions and institutions can be challenging and often arbitrary. Due to this lack of standard analytical methods for faecal sludge, methods from other fields, such as wastewater management, and soil and food science are frequently applied. However, these methods are not necessarily the most suitable for faecal sludge analysis, and have not been specifically adapted for this purpose. Characteristics of faecal sludge can be different than these other matrices by orders of magnitude. There is also a lack of standard methods for sampling, which is complicated by the difficult nature of in situ sampling, the wide range of onsite sanitation technologies and potential sampling locations, and the diverse heterogeneity of faecal sludge within onsite containments and within cities. This illustrates the urgent need to establish common methods and procedures for faecal sludge characterisation, quantification, sampling, and modelling. The aim of this book is to provide a basis for standardised methods for the analysis of faecal sludge from onsite sanitation technologies, for improved communication between sanitation practitioners, and for greater confidence in the generated data. The book presents background information on types of faecal sludge, methods for sample collection, health and safety procedures for handling, case studies of experimental design, an approach for estimating faecal sludge at community to city-wide scales, modelling containment and treatment processes, recipes for simulants, and laboratory methods for faecal sludge analysis currently in use by faecal sludge laboratories. This book will be beneficial for researchers, laboratory technicians, academics, students and sanitation practitioners. ISBN13: 9781780409115 eISBN: 9781780409122

In this chapter the crucial role of units and dimensions in the analysis of any problem involving physical quantities is explained. The International System of Units (SI) is introduced. The major advantage of collecting the physical quantities, which are included in either a theoretical analysis or an experiment, into non-dimensional groups is shown to be a reduction in the number of quantities which need to be considered separately. This process, known as dimensional analysis, is based upon the principle of dimensional homogeneity. Buckingham’s Π‎ theorem is introduced as a method for determining the number of non-dimensional groups (the Π‎’s) corresponding with a set of dimensional quantities and their dimensions. A systematic and simple procedure for identifying these groups is the sequential elimination of dimensions. The scale-up from a model to a geometrically similar full-size version is shown to require dynamic similarity. The definitions and names of the non-dimensional groups most frequently encountered in fluid mechanics have been introduced and their physical significance explained.

Milton Babbitt (1916–2011) was, at once, one of the century’s foremost composers and a founder of American music theory. These two aspects of his creative life—“thinking in” and “thinking about” music, as he would put it—nourished each other. Theory and analysis inspired fresh compositional ideas, and compositional concerns focused theoretical and analytical inquiry. Accordingly, this book undertakes an excavation of the sources of his theorizing as a guide to analysis of his music. Babbitt’s idiosyncratic synthesis of ideas from Heinrich Schenker, analytic philosophy, and cognitive science—at least as much as more obviously relevant, and more frequently cited, predecessors such as Arnold Schoenberg—provide insight into his aesthetics and compositional technique. Examination of Babbitt’s newly available sketch materials sheds additional light on his procedures. But a close look at his music reveals a host of concerns unaccounted for in his theories, some of which seem to directly contradict theoretical expectations. New analytical models are needed to complement those suggested by Babbitt’s theories. Departing from the serial logic of Babbitt’s writings, his compositional procedures, and most previous work on the subject—and in an attempt to discuss Babbitt’s music as it is actually heard rather than just deciphered—the book brings to bear theories of gesture and embodiment, rhetoric, text setting, and temporality. The result is a richly multifaceted look at one of the twentieth century’s most fascinating musical minds.

International arbitration is a remarkably resilient institution, but many unresolved and largely unacknowledged ethical quandaries lurk below the surface. Globalization of commercial trade has increased the number and diversity of parties, counsel, experts, and arbitrators, which have in turn, led to more frequent ethical conflicts just as procedures have become more formal and transparent. The predictable result is that ethical transgressions are increasingly evident and less tolerable. Despite these developments, regulation of various actors in the system — arbitrators, lawyers, experts, third-party funders, and arbitral institutions — remains ambiguous and often ineffectual. This book systematically analyses the causes and effects of these developments as they relate to the professional conduct of arbitrators, counsel, experts, and third-party funders in international commercial and investment arbitration. This work proposes a model for effective ethical self-regulation, meaning regulation of professional conduct at an international level and within existing arbitral procedures and structures. The work draws on historical developments and current trends to propose analytical frameworks for addressing existing problems and reifying the legitimacy of international arbitration into the future.

This work is a critical update of the most recent and innovative developments of the avalanche science. It aims at re-founding it on clear scientific bases, from field observations and experiments up to strong mathematical and physical analysis and modeling. It points out snow peculiarities, regarding both static mechanical properties and flow dynamics, that may strongly differ from those of compact solids for the former, and of Newtonian fluids for the latter. It analyzes the general processes involved in avalanche release, in terms of brittle fracture and ductile plasticity, specific friction laws, flow of healable granular materials, percolation concepts, cellular automata, scale invariance, criticality, theory of dynamical systems, bifurcations, etc. As a result, slab triggering (including remote triggering) can be summarized by the “slab avalanche release in 4 steps” concept, based on weak layer local collapse and subsequent propagation driven by slab weight. The frequent abortion of many incipient avalanches is easily explained in terms of snow grain dynamical healing. Sluffs and full-depth avalanches are also analyzed. Such advances pave the way for significant progress in risk evaluation procedures. In the present context of a speeding-up climate warming, possible evolutions of snow cover extent and stability are also tentatively discussed. We show how, in mountainous areas, the present analysis can be extended to other gravitational failures (rock-falls, landslides) that are likely to take over from avalanches in such circumstances. The text is supported by on-line links to field experiments and lectures on triggering mechanisms, risk management, and decision making.

The chapter begins by clarifying what is meant by ‘private ordering’ in family law—where the primary focus is usually not on the fact of private ordering, but the question of state recognition or enforcement of private choices. Additionally, the analysis considers the distinction between agreements regarding substantive outcomes (e.g. who should have parental rights), and agreements regarding procedure (e.g. having a dispute settled by arbitration). The chapter offers an overview of the moral and policy arguments that had been raised when private ordering had been strongly discouraged (e.g. various social goods, and the protection of vulnerable parties), and the changing arguments being offered now that private ordering is more frequently encouraged, or at least condoned. Finally, the chapter will consider why some forms of private ordering (e.g. separation agreements at divorce) are encouraged, while others (e.g. co-parenting and surrogacy agreements) continue to be treated with suspicion.

Due diligence is a prominent concept in international law. Still, for long, its role seemed to be that of a familiar stranger. Frequent referrals to the concept in arbitral awards, court decisions, and in scholarly discussions mostly on state responsibility hide the fact that the specific normative content and systemic relation of due diligence to rules and principles of international law has largely remained unexplored. The present book provides the first comprehensive analysis of the content, scope, and function of due diligence across various areas of international law, including international environmental law, international peace and security law, and international economic law. Sector by sector, contributors explore the diverse interactions between due diligence and area-specific substantive and procedural rules as well as general principles of international law. The book exposes the promises and limits of due diligence for enhancing accountability and compliance and identifies the rise of due diligence as a signal for change in the international legal order towards risk management and proceduralisation.

Deliberative democracy has challenged two widely accepted nostrums about democratic politics: that people lack the capacities for effective self-government; and that democratic procedures are arbitrary and do not reflect popular will; indeed, that the idea of popular will is itself illusory. On the contrary, deliberative democrats have shown that people are capable of being sophisticated, creative problem solvers, given the right opportunities in the right kinds of democratic institutions. But deliberative empirical research has its own problems. In this book two leading deliberative scholars review decades of that research and reveal three important issues. First, the concept ‘deliberation’ has been inflated so much as to lose empirical bite; second, deliberation has been equated with entire processes of which it is just one feature; and third, such processes are confused with democracy in a deliberative mode more generally. In other words, studies frequently apply micro-level tools and concepts to make macro- and meso-level judgements, and vice versa. Instead, Bächtiger and Parkinson argue that deliberation must be understood as contingent, performative, and distributed. They argue that deliberation needs to be disentangled from other communicative modes; that appropriate tools need to be deployed at the right level of analysis; and that scholars need to be clear about whether they are making additive judgements or summative ones. They then apply that understanding to set out a new agenda and new empirical tools for deliberative empirical scholarship at the micro, meso, and macro levels.

The impact of the Oulipo (Ouvroir de Littérature Potentielle), one of the most important groups of experimental writers of the late twentieth century, is still being felt in contemporary literature, criticism and theory, both in Europe and the US. Founded in 1960 and still active today, this Parisian literary workshop has featured among its members such notable writers as Italo Calvino, Georges Perec, and Raymond Queneau, all sharing in its light-hearted, slightly boozy bonhomie, the convivial antithesis of the fractious, volatile coteries of the early twentieth-century avant-garde. For the last fifty years the Oulipo has undertaken the same simple goal: to investigate the potential of ‘constraints’ in the production of literature—that is, formal procedures such as anagrams, acrostics, lipograms (texts which exclude a certain letter), and other strange and complex devices. Yet, far from being mere parlour games, these methods have been frequently used as part of a passionate—though sometimes satirical—involvement with the major intellectual currents of the mid-twentieth century. Structuralism, psychoanalysis, Surrealism, analytic philosophy: all come under discussion in the group’s meetings, and all find their way in the group’s exercises in ways that, while often ironic, are also highly informed. Using meeting minutes, correspondence, and other material from the Oulipo archive at the Bibliothèque nationale de France, The Oulipo and Modern Thought shows how the group have used constrained writing as means of puckish engagement with the debates of their peers, and how, as the broader intellectual landscape altered, so too would the group’s conception of what constrained writing can achieve.

Oil spills can be difficult to manage, with reporting frequently delayed. Too often, by the time responders arrive at the scene, the slick has moved, dissolved, dispersed or sunk. This Oil Spill Monitoring Handbook provides practical advice on what information is likely required following the accidental release of oil or other petroleum-based products into the marine environment. The book focuses on response phase monitoring for maritime spills, otherwise known as Type I or operational monitoring. Response phase monitoring tries to address the questions – what? where? when? how? how much? – that assist responders to find, track, predict and clean up spills, and to assess their efforts. Oil spills often occur in remote, sensitive and logistically difficult locations, often in adverse weather, and the oil can change character and location over time. An effective response requires robust information provided by monitoring, observation, sampling and science. The Oil Spill Monitoring Handbook completely updates the Australian Maritime Safety Authority’s 2003 edition of the same name, taking into account the latest scientific advances in physical, chemical and biological monitoring, many of which have evolved as a consequence of major oil spill disasters in the last decade. It includes sections on the chemical properties of oil, the toxicological impacts of oil exposure, and the impacts of oil exposure on different marine habitats with relevance to Australia and elsewhere. An overview is provided on how monitoring integrates with the oil spill response process, the response organisation, the use of decision-support tools such as net environmental benefit analysis, and some of the most commonly used response technologies. Throughout the text, examples are given of lessons learned from previous oil spill incidents and responses, both local and international. General guidance of spill monitoring approaches and technologies is augmented with in-depth discussion on both response phase and post-response phase monitoring design and delivery. Finally, a set of appendices delivers detailed standard operating procedures for practical observation, sample and data collection. The Oil Spill Monitoring Handbook is essential reading for scientists within the oil industry and environmental and government agencies; individuals with responder roles in industry and government; environmental and ecological monitoring agencies and consultants; and members of the maritime sector in Australia and abroad, including officers in ports, shipping and terminals.

These Guidelines are one of the results of the four-year research project “Open Online Learning for Digital and Networked Society” (2017-2021). The project objective was to enable university teachers to design open and online learning through open and online learning curriculum and environment applying learning analytics as a metacognitive tool and creating open and online learning assessment and recognition practices, responding to the needs of digital and networked society. The research of the project resulted in 10 scientific publications and 2 studies prepared by Vytautas Magnus university Institute of Innovative Studies research team in collaboration with their international research partners from Germany, Spain and Portugal. The final stage of the research attempted creating open and online learning assessment and recognition practices, responding to the learner needs in contemporary digital and networked society. The need for open learning recognition has been increasing during the recent decade while the developments of open learning related to the Covid 19 pandemics have dramatically increased the need for systematic and high-quality assessment and recognition of learning acquired online. The given time also relates to the increased need to offer micro-credentials to learners, as well as a rising need for universities to prepare for micro-credentialization and issue new digital credentials to learners who are regular students, as well as adult learners joining for single courses. The increased need of all labour - market participants for frequent and fast renewal of competences requires a well working and easy to use system of open learning assessment and recognition. For learners, it is critical that the micro-credentials are well linked to national and European qualification frameworks, as well as European digital credential infrastructures (e.g., Europass and similar). For employers, it is important to receive requested quality information that is encrypted in the metadata of the credential. While for universities, there is the need to properly prepare institutional digital infrastructure, organizational procedures, descriptions of open learning opportunities and virtual learning environments to share, import and export the meta-data easily and seamlessly through European Digital Hub service infrastructures, as well as ensure that academic and administrative staff has digital competencies to design, issue and recognise open learning through digital and micro-credentials. The first chapter of the Guidelines provides a background view of the European Qualification Framework and National Qualification frameworks for the further system of gaining, stacking and modelling further qualifications through open online learning. The second chapter suggests the review of current European policy papers and consultations on the establishment of micro-credentials in European higher education. The findings of the report of micro-credentials higher education consultation group “European Approach to Micro-credentials” is shortly introduced, as well as important policy discussions taking place. Responding to the Rome Bologna Comunique 2020, where the ministers responsible for higher education agreed to support lifelong learning through issuing micro-credentials, a joint endeavour of DG Employment, Social Affairs and Inclusion and DG Research and Innovation resulted in one of the most important political documents highlighting the potential of micro-credentials towards economic, social and education innovations. The consultation group of experts from the Member States defined the approach to micro-credentials to facilitate their validation, recognition and portability, as well as to foster a larger uptake to support individual learning in any subject area and at any stage of life or career. The Consultation Group also suggested further urgent topics to be discussed, including the storage, data exchange, portability, and data standards of micro-credentials and proposed EU Standard of constitutive elements of micro-credentials. The third chapter is devoted to the institutional readiness to issue and to recognize digital and micro-credentials. Universities need strategic decisions and procedures ready to be enacted for assessment of open learning and issuing micro-credentials. The administrative and academic staff needs to be aware and confident to follow these procedures while keeping the quality assurance procedures in place, as well. The process needs to include increasing teacher awareness in the processes of open learning assessment and the role of micro-credentials for the competitiveness of lifelong learners in general. When the strategic documents and procedures to assess open learning are in place and the staff is ready and well aware of the processes, the description of the courses and the virtual learning environment needs to be prepared to provide the necessary metadata for the assessment of open learning and issuing of micro-credentials. Different innovation-driven projects offer solutions: OEPass developed a pilot Learning Passport, based on European Diploma Supplement, MicroHE developed a portal Credentify for displaying, verifying and sharing micro-credential data. Credentify platform is using Blockchain technology and is developed to comply with European Qualifications Framework. Institutions, willing to join Credentify platform, should make strategic discussions to apply micro-credential metadata standards. The ECCOE project building on outcomes of OEPass and MicroHE offers an all-encompassing set of quality descriptors for credentials and the descriptions of learning opportunities in higher education. The third chapter also describes the requirements for university structures to interact with the Europass digital credentials infrastructure. In 2020, European Commission launched a new Europass platform with Digital Credential Infrastructure in place. Higher education institutions issuing micro-credentials linked to Europass digital credentials infrastructure may offer added value for the learners and can increase reliability and fraud-resistant information for the employers. However, before using Europass Digital Credentials, universities should fulfil the necessary preconditions that include obtaining a qualified electronic seal, installing additional software and preparing the necessary data templates. Moreover, the virtual learning environment needs to be prepared to export learning outcomes to a digital credential, maintaining and securing learner authentication. Open learning opportunity descriptions also need to be adjusted to transfer and match information for the credential meta-data. The Fourth chapter illustrates how digital badges as a type of micro-credentials in open online learning assessment may be used in higher education to create added value for the learners and employers. An adequately provided metadata allows using digital badges as a valuable tool for recognition in all learning settings, including formal, non-formal and informal.
