This chapter is on communication complexity, which measures the minimum number of bits that two parties must exchange to collaboratively compute a function when the input is split between the parties. Techniques for upper and lower bounds for deterministic and randomized communication complexities are covered. The chapter also presents applications of communication complexity to topics that don’t involve explicit communication, such as streaming algorithms, data structures, and integrated circuit layout.

In this chapter, we examine how the basic principles and structure of IPT have evolved, and how fundamental treatment components and strategies have become refined or expanded with dissemination are outlined. We look through the lens of a practicing IPT therapist and illustrate the orientation, framework and implementation of IPT for contemporary application. Interpersonal Psychotherapy (IPT) is a time-limited (16–20 session), evidence-based psychological therapy which focuses on mood and interpersonal relationships. IPT recognises the significance of life events, particularly those involving interpersonal relationships, which often coincide with the onset of an episode of depression. The therapy is structured around three key principles: (1) a clear focus on interpersonal issues exploring and addressing interpersonal difficulties as they relate to a person’s emotional distress, concentrating on present relationships, (2) the identification of one of four main focus/problem areas, grief, role transitions, interpersonal role disputes or interpersonal sensitivities and (3) treatment structured into three phases – Beginning (1–4); Middle (5–12) and Ending (13–16). IPT sets clear goals to alleviate the presenting symptoms and improve interpersonal functioning. The IPT therapist helps clients to explore emotions, understand patterns in relationships and develop strategies to address the identified problem.

The process of researching, planning and writing a persuasive essay is a fundamental task in the study of law. A well-planned and well-executed essay shows that you have knowledge and that you can apply that knowledge persuasively in relation to an argument. This form of assessment is used less often in the law than in other humanities subjects, but the skills you obtain by becoming proficient at this sort of writing will certainly assist you in any type of endeavour which requires you to form coherent arguments. Remember that the key to the whole process is to do the preparatory work before you begin writing. An essay with a strong underlying structure is almost certainly going to be a strong essay. Where an essay has been written by a student who has not taken the time to plan, this will, unfortunately, be obvious to the marker, and will result in lower grades every time. Understand the topic, develop your one-sentence answer to the question, plan the structure, add your research – and you will write an excellent essay.

In this chapter, urban and natural ecosystems are compared and contrasted. The chapter starts with definitions of both ecosystems and presents the case of the urban ecosystem as a striking example of environmental engineering typical for various living organisms. It proceeds by describing differences in overground and underground structures of natural and urban ecosystems. Energy, water, and nutrient inputs required for the functioning of both ecosystems are discussed thereafter. An overview of gaseous, liquid, and solid outputs from urban and natural ecosystems concludes this chapter. The consequences of these differences for the environment and humans are discussed in Chapters 4, 5, and 6 in detail.

This chapter describes the internal environment of a financial institution.

This introduction establishes a foundation for the chapters that follow by providing an overview of Vasari’s work at Santa Maria della Pieve in Arezzo and the state of the research on the topic. It also maps out the structure of the book, identifies the methodologies and primary and secondary source material upon which it is based, and establishes its contribution to the literature on Vasari and the history of Italian Renaissance art.

This chapter explores strategy as a key driver of organizational design, emphasizing that structure should align with strategic intent. It introduces four strategic archetypes: reactors (no clear strategy), defenders (efficiency-focused), prospectors (innovation-driven), and analyzers (balancing both). It also discusses digital business strategy, showing how AI and digitalization reshape decision-making, operations, and innovation. Sustainable strategy is introduced, integrating economic, environmental, and social goals (People, Planet, Profit) to enhance resilience and competitiveness. The chapter concludes with strategy misfits – misalignments between strategy and goals – and the need to adjust one or the other. It ends by addressing how the environment influences strategic choices.

The function, composition and processes underlying the formation and maturation of the skeleton, bone the organ and bone the tissue, are the focus of this chapter. Knowledge of the immature infant skeleton and its inherent weaknesses and susceptibility to physical injury, facilitates understanding the morphologic manifestations of bone injury and the body’s response to associated tissue damage. The skeleton is a complex structure that plays a variety of different roles crucial to life. It is composed of many individual bones that are constructed of proteins, minerals and the cells specific to bone, namely, the families of osteoblasts and osteoclasts. Bones form through enchondral and intramembranous ossification, and these processes are complex and tightly regulated by molecular genetics and cell-signaling pathways. Understanding the structure of the skeleton and its growth and development provides the foundation to understand its susceptibility to trauma and the pathology induced by injury and tissue damage.

This chapter examines the role and nature of theory in big picture analysis. It argues that while Buzan-style big picture analysis necessarily engages a specific perspective, it does not tell us anything about the nature of the theory used. That is, what concepts does it consist of? How are they organized? And what kind of inner mechanisms make it tick? This chapter demonstrates that Buzan-style big picture analysis is enabled by a theory quite distinct from other standard types of theorizing in International Relations. Uniquely, Buzan understands theory as a network of concepts, hierarchically organized, that allows a mapping of issues and thus corresponding to the mindmapping© technique. As such, theory does not have a lasting form, but shifts in accordance with empirics. In Buzan’s case, most of the key concepts come from the English School (within International Relations), mixed up with standard terminology from macro-history and historical sociology. Beyond that, I argue, that Buzan – like many in IR – has evolved through an engagement with Waltzian neorealism. I examine to what extent traces of Waltz remain in Buzan’s approach and go on to suggest that there is space within Buzan’s framework for developing theories in the Waltzian sense as pictures mentally formed, sporting a constant form holding across space and time.

This chapter explores the structure–culture–agency interplay in the English language learning context of Cancun, Mexico. The body of empirical data is analysed through CR-grounded linguistic ethnography. Of specific interest are three Mexican students’ reflexive deliberations and strategies to position themselves in relation to the English language, its symbolic and economic value, and to broader structural and cultural forces, in the fulfilment of their goals. Analysis of the findings reveals the powerful influence of social class distribution partly based on ethnicity, and the role of language learner reflexivity in the adoption of diverse approaches to English language learning. The study of reflexivity in this chapter shows how agentive processes lead to different degrees of investment and successes, including resistance to and acceptance of the necessity for English in relation to Cancun’s social and economic context. Analysis also reveals English as the language of the dominant yet not fully accepted North American culture, and how it is seen a paramount tool in the fulfilment of personal and communal projects in the context of Cancun.

This chapter explores the folk and traditional music of Scotland, Ireland, and Wales – the so-called Celtic regions of the British Isles – in terms of the concepts and processes through which such music is made, representing both the everyday and the elite, past and present; modalities, in short, that I feel represent a timeless importance to our aesthetic understanding and a foundation for negotiating traditional music’s social and historical value today. Threading loosely through my exploration of these modalities is what ethnomusicologist Constantin Brăiloiu called ‘the problem of creation’, which serves as a useful lens through which I remark on the making of traditional music as a complex interplay of function, acquisition, structure, symmetry, orality, improvisation, variation, literacy, and memory. I present these modalities chiefly through the prism of Scottish music owing to its significance in the historical discourse surrounding our very concept of the folk.

Reviews the empirical and conceptual findings, makes forecasts about the future likelihood of the use of force in each category of conflict, the role of learning and non-learning in the decline of war, why the great powers are still more committed to the use of force than other states, and the prospects for weaning them from violence.

This chapter briefly engages with contemporary approaches to the study of nations and nationalisms and offers a critique of the structuralist and agency-centred explanations. The chapter also articulates the theoretical framework that is then applied to a variety of case studies in the book. The chapter outlines the key features of the approach and describes how nationalist grounding operates on coercive-organisational, ideological, and micro-interactional levels.

The first chapter offers a genealogy of the idea of genesis in various philosophers and social scientists starting from the pre-socratics up to the recent work of late Gerard Duveen. The vision of genetic social psychology and key theoretical influences are discussed in detail. The triadic model of subject-object-other is the unit of analysis of this proposal, and an articulation of different levels of analysis is proposed in our effort to understand the relationship between the process of microgenesis, ontogenesis and sociogenesis. It highlights the importance of the work of Hans Furth and Lucien Goldmann as key influences on Gerard Duveen and his own vision of an integrative social developmental psychology that combines ideas from Piaget and Moscovici. In this chapter I also discuss the work of other researchers interested in ideas relating to these two great theorists of the social sciences.
