At all ages, children interpret and respond to the emotions of others. Traditionally, it has been assumed that children’s emotion knowledge was based on an early understanding of facial expressions in terms of specific, discrete emotions. More recent evidence suggests that this assumption is incorrect. As described by the broad-to-differentiated hypothesis, children’s initial emotion concepts are broad and valence based. Gradually, children differentiate within these initial concepts by linking the different components of an emotion together (e.g., the cause to the consequence, etc.) until their concepts resemble adults’ emotion concepts. Contrary to traditional assumptions, facial expressions are neither the starting point for most emotion concepts nor are they the strongest cue to emotions. Instead, just like any other component of an emotion concept, facial expressions must be differentiated from the valence-based concepts and linked to the other components of the specific emotion concept.

This chapter covers the one-dimensional Kardar–Parisi–Zhang equation, weak drive limit, universality, directed polymers in a random medium, replica solutions, statistical mechanics of line ensembles, and its generalization to several components which is used to study equilibrium time correlations of anharmonic chains and of the discrete nonlinear Schrödinger equation.

Chapter 1 introduces and explores the book’s central thesis through considering practices by Donne’s early readers, placing this study into recent critical conversations on Donne and manuscript culture, and establishing its contribution to such conversations. In addition to adding several discrete examples of manuscript investigations that suggest early interpretive responses to Donne’s texts, this chapter advances a methodological approach for examining literary works within original artifacts: it delineates manuscript elements to investigate in order to uncover clues regarding early modern literary interpretations. These components include provenance, papers and how they were constructed into books, scribes, marginalia, titles, ascriptions, paratexts, and contents and their sequences. Because one cannot anticipate which elements will prove most informative for any given manuscript, all components require attention. This pragmatic approach to manuscript study encourages scholars to embark on explorations traditionally relegated to bibliography and textual studies that actually prove essential to literary criticism.

The notion that there are universal facial expressions of basic emotion remains a dominant idea in the study of emotion. Inspired by pragmatics, and based on behavioral ecology and psychological constructionism, this chapter provides an alternative to the concept of facial expression of basic emotion: the concept of natural facial expression. Actual, observable natural facial expressions do not mean self-contained, discrete basic emotions; they are instead related to different components of diverse emotional episodes. Their communicative function is not semantic (e.g., a smile does not means happiness) but pragmatic (e.g., a smile prompts, on the receiver’s side, important inferences about the context and course of the interaction between sender and receiver).

This chapter offers an alternative account to the basic emotion theory. In my alternative, termed psychological construction, episodes called “emotional” consist of changes in various component processes (peripheral physiological changes, information processing including appraisals and attributions, expressive and instrumental behavior, subjective experiences), no one of which is itself an emotion or necessary or sufficient for an emotion to be instantiated. One hypothesis, for example, is that the production of facial expressions is accounted for by one or more of various alternative sources(such as perception, cognition, signaling of intented behavior, paralanguage, preparation for action, or core affect), not by a discrete emotion or affect program dedicated exclusively to emotion or to a specific emotion.

This article discusses musical-timbre perception. Musical timbre is a combination of continuous perceptual dimensions and discrete features to which listeners are differentially sensitive. The continuous dimensions often have quantifiable acoustic correlates. The timbre-space representation is a powerful psychological model that allows predictions to be made about timbre perception in situations beyond those used to derive the model in the first place. Timbre can play a role in larger-scale movements of tension and relaxation and thus contribute to the expression inherent in musical form. Under conditions of high blend among instruments composing a vertical sonority, timbral roughness is a major component of musical tension. However, it strongly depends on the way auditory grouping processes have parsed the incoming acoustic information into events and streams.

While there is increasing research on the benefits and facilitators of compassion, as with all motives, there are inhibitors. This chapter will not cover the benefits of compassion, explored in other chapters, but instead considers its inhibitors: the fears, blocks, and resistances (FBRs) to compassion and their evolutionary and psychosocial origins. We begin with an explication of a model for compassion, and show how compassion rests on discrete components and competencies that can be differentially inhibited. Next, we utilize Ernst Mayr’s (1961) classic heuristic to understand compassion inhibition; namely, the “ultimate” and “proximate” analysis. We conclude with an exploration of the antidotes to these inhibitors. Greater research into the nature of compassion inhibitors and insights on how to address them could increase the use of compassion in different domains of life.

Tracing parallels between material and verbal poetics, this chapter makes particular reference to changing conceptions of metaphor and imagery during the florescence of medieval Arabic literary theory. It uses textual sources as well as artifacts to demonstrate the intertwining of verbal, visual, and material realms. The first section expands an allegorical framework in medieval Arabic and Persian literary criticism that aligns poetry with manual crafts. Following this, two discrete groups of objects in the form of domed buildings are contextualized and considered as materialized metaphors. First, cast-metal incense burners of the eighth or ninth centuries are placed into an expanded context of eastern Mediterranean portable arts and architectural components. The second group, lanterns from the twelfth and thirteenth centuries, reflect a later period when the central-plan domed monument had been fully assimilated into Islamic architectural practice as a standard form of commemorative architecture.

Photomultipliers (PMTs) are current generators characterized by high gain, wide bandwidth, and high-output impedance. The role of preamplifiers and amplifiers is generally one of conditioning the PMT output. Either the time signature is preserved using a fast voltage preamplifier, or a voltage proportional to the charge in each event is generated with a charge-sensitive preamplifier. Both preamplifier types are generally of low-output impedance, suitable for driving matched coaxial cable. Preamplifiers and amplifiers are available as modular units (e.g. nuclear instrument module), stand alone, or are incorporated in a module including the PMT. Shaping amplifiers are used to further condition preamplifier signals, using integrating and differentiating circuits—particularly relevant to scintillation spectrometers. Discrete-component amplifiers and current-feedback operational amplifiers serve fast applications. Digital signal processing has overtaken many of the classical electronic techniques involving resolution and in pulse shape discrimination. Electronic circuitry for generating fast LED pulses is discussed.

All books in this flagship series contain carefully selected substantial extracts from key cases, legislation, and academic debate, providing able students with a stand-alone resource. A crucial component of the Commission’s task is to monitor Member State compliance and to respond to non-compliance. The Treaty on the Functioning of the European Union (TFEU) provides for various enforcement mechanisms involving judicial proceedings against the Member States, which are brought either by the Commission or - much less frequently - by a Member State. Article 258 TFEU establishes the general enforcement procedure, giving the Commission broad power to bring enforcement proceedings against Member States that it considers to be in breach of their obligations under EU law. This chapter discusses the function and operation of the infringement procedure; the relationship between ‘public’ and ‘private’ enforcement mechanisms; the Commission’s discretion; types of breach by Member States of EU law; state defences in enforcement proceedings; and the consequences of an Article 258 ruling.

The recent threats to cultural heritage, including in Iraq, Mali, Nepal, Syria, and Yemen, has led to increased focus on the sources of international cultural heritage law. This volume reflects that this is not a discrete and contained body of law, but rather a diverse one whose components are drawn from—and often developed and contained within—public international law. These ‘intersections’ have formed in two ways: when public international law has been used to provide greater protection for cultural heritage; and when concern for cultural heritage protection or codification of rules within cultural heritage-centric instruments have helped fuel developments within other areas of public international law. In this volume, scholars and practitioners explore some of the primary points of intersection where international cultural heritage law and public international law converge. The contributions are organized according to five major ‘intersections’: (1) the Law of Armed Conflict and the Protection of Cultural Heritage; (2) Cultural Heritage-Based Offenses in International Criminal Law and in Laws for Combatting Transnational Organized Crime; (3) the United Nations System and the Protection of Cultural Heritage; (4) Special Legal Regimes for the World Cultural Heritage and Underwater Cultural Heritage; and (5) Intersections of International, National, and Community Interests in Cultural Heritage. The result is a diverse and cohesive collection that explores these intersections and examines how the regimes operate together and how the relationship between them largely facilitates, but also sometimes hinders, the development of international law governing the protection of cultural heritage.

The legal status of plant genetic resources has been subject to numerous international agreements and laws over the centuries. The “common heritage of mankind” approach enabled free access but proved unworkable because of conflicts over intellectual property rights. The Convention on Biological Diversity (1992) recognized sovereign rights of nations over genetic resources within their territory. The Trade Related Intellectual Property Rights Agreement under auspices of the World Trade Organization mandated intellectual property protection for plant varieties, but synchronizing such rights has proved problematic. Many developing countries have enacted sui generis regimes to comply with TRIPS requirements. The International Union for the Protection of New Varieties of Plants Convention provides models that have changed over time. With the advent of agricultural biotechnology and availability of intellectual property rights for plant components, patents relating to plant genetic resources have increased. As plant genetic resources are subject to many overlapping treaties, the regime governing them is becoming more complex, resulting in inconsistencies and disputes. While the rights of plant breeders and the private seed industry are well protected in formal agreements, the rights of farmers, who have nurtured diversity in plant genetic resources, developed varieties of crops with different traits, and contributed to exchange and conservation of plant genetic resources, are left to the discretion of nation-states. Farmers’ rights are mentioned in many international legal instruments, but no binding treaty or convention mandates protecting and promoting the rights of working farmers.

The climate system consists of interactions between physical, biological, chemical, and human processes across a wide range of spatial and temporal scales. Characterizing the behavior of components of this system is crucial for scientists and decision makers. There is substantial uncertainty associated with observations of this system as well as our understanding of various system components and their interaction. Thus, inference and prediction in climate science should accommodate uncertainty in order to facilitate the decision-making process. Statistical science is designed to provide the tools to perform inference and prediction in the presence of uncertainty. In particular, the field of spatial statistics considers inference and prediction for uncertain processes that exhibit dependence in space and/or time. Traditionally, this is done descriptively through the characterization of the first two moments of the process, one expressing the mean structure and one accounting for dependence through covariability.Historically, there are three primary areas of methodological development in spatial statistics: geostatistics, which considers processes that vary continuously over space; areal or lattice processes, which considers processes that are defined on a countable discrete domain (e.g., political units); and, spatial point patterns (or point processes), which consider the locations of events in space to be a random process. All of these methods have been used in the climate sciences, but the most prominent has been the geostatistical methodology. This methodology was simultaneously discovered in geology and in meteorology and provides a way to do optimal prediction (interpolation) in space and can facilitate parameter inference for spatial data. These methods rely strongly on Gaussian process theory, which is increasingly of interest in machine learning. These methods are common in the spatial statistics literature, but much development is still being done in the area to accommodate more complex processes and “big data” applications. Newer approaches are based on restricting models to neighbor-based representations or reformulating the random spatial process in terms of a basis expansion. There are many computational and flexibility advantages to these approaches, depending on the specific implementation. Complexity is also increasingly being accommodated through the use of the hierarchical modeling paradigm, which provides a probabilistically consistent way to decompose the data, process, and parameters corresponding to the spatial or spatio-temporal process.Perhaps the biggest challenge in modern applications of spatial and spatio-temporal statistics is to develop methods that are flexible yet can account for the complex dependencies between and across processes, account for uncertainty in all aspects of the problem, and still be computationally tractable. These are daunting challenges, yet it is a very active area of research, and new solutions are constantly being developed. New methods are also being rapidly developed in the machine learning community, and these methods are increasingly more applicable to dependent processes. The interaction and cross-fertilization between the machine learning and spatial statistics community is growing, which will likely lead to a new generation of spatial statistical methods that are applicable to climate science.
