This chapter describes the data collection strategy and multimethod research design employed to test the theory in the subsequent chapters of the book. The structure of the empirical analysis mirrors the book’s primary argument: to show how peacekeeping works from the bottom up, from the individual to the community to the country. Given that UN peacekeepers deploy to the most violent areas, the design needed to account for selection bias as well as other confounding variables in order to make causal inference possible. Using data from individual- and subnational/community-level data from Mali as well as cross-national data from the universe of multidimensional PKOs deployed in Africa, the book employs a three-part strategy to test the hypotheses in the next few chapters. First, the book considers the micro-level behavioral implications of the theory using a lab-in-the-field experiment and a survey experiment, both implemented in Mali. Second, it test whether UN peacekeepers’ ability to increase individual willingness to cooperate aggregates upward to prevent communal violence in Mali. Third, the book considers whether these findings extend to other countries.

The implicit revolution seems to have arrived with the declaration that “explicit measures are informed by and (possibly) rendered invalid by unconscious cognition.” What is the view from survey research, which has relied on explicit methodology for over a century, and whose methods have extended to the political domain in ways that have changed the landscape of politics in the United States and beyond? One survey researcher weighs in. The overwhelming evidence points to the continuing power of explicit measures to predict voting and behavior. Whether implicit measures can do the same, especially beyond what explicit measures can do, is far more ambiguous. The analysis further raises doubts, as others before have done, as to what exactly implicit measures measure, and particularly questions the co-opting among implicit researchers the word “attitude” when such measures instead represent associations. The conclusion: Keep your torches at home. There is no revolution.

The move from theory to empirics requires figuring out how to collect evidence that could support or disconfirm hypotheses derived from your theory. Empirically studying the network in your theory requires two steps: determining which nodes to include in your data and operationalizing the link type. This chapter helps a reader select the boundary that contains the nodes of interest, pointing out some subtle downsides to random sampling in network studies. It also helps readers determine whether they want to measure full networks or ego ones and offers pointers on operationalizing link types.

Students are introduced the logic, foundation, and basics of statistical inference. The need for samples is first discussed and then how samples can be used to make inferences about the larger population. The normal distribution is then discussed, along with Z-scores to illustrate basic probability and the logic of statistical significance.

Gives a brief overview of the book. Notations for signal representation in continuous time and discrete time are introduced. Both one-dimensional and two-dimensional signals are introduced, and simple examples of images are presented. Examples of noise removal and image smoothing (filtering) are demonstrated. The concept of frequency is introduced and its importance as well as its role in signal representation are explained, giving musical notes as examples. The history of signal processing, the role of theory, and the connections to real-life applications are mentioned in an introductory way. The chapter also draws attention to the impact of signal processing in digital communications (e.g., cell-phone communications), gravity wave detection, deep space communications, and so on.

This introductory chapter sets out the aim of the project, which is to reassess the social and cultural relations between the Aegean and the Mediterranean through a new examination of some of the earliest Greek pottery finds overseas. The focus is on Protogeometric and Geometric ceramics from Greek and Phoenician colonies, certain Phoenician metropolises and further Indigenous sites in the Aegean and the Mediterranean, which were analysed by Neutron Activation. The analytical results are examined against the background of the social and economic relations that were generated through the production, exchange and consumption of the pottery finds under scrutiny.

Chapter 3 focuses on WTO disputes about anti-dumping issues. Anti-dumping or to be more specific, zeroing is the single-most litigated issue under WTO law. Although the Appellate Body has found zeroing method inconsistent with ADA several times, it is still being used with small alterations. Chapter 3 shows that the so-called jewel in the crown is sometimes ineffective. To do so, the role of the DSM in the anti-dumping issue is presented and anti-dumping cases dealing with procedural issues are analysed. The procedural issues mentioned in this chapter are as follows: calculation methods, transparency, public notice/notification, selection of investigated parties (sampling), submission of evidence and rebuttals, access to non-confidential files, hearings, newcomers and enforcement.

This chapter explores the evolution of the djent subgenre from the perspective of the musical, technological and environmental factors that have shaped its identity. The chapter considers the early circumstances of djent’s emergence during the early mid−2000s, with particular reference to the online culture which contributed to its wider transmission and proliferation. Key musical influences are also discussed, including djent’s roots in progressive metal and the work of bands such as Meshuggah and SikTh, as well as the subgenre’s interaction with electronic music aesthetics and popular music. A principal focus of the chapter is on the role of emerging digital technologies, particularly Digital Audio Workstations (DAW) and digital amplifier and drum kit modelling software, in the formation of djent’s musical and sonic characteristics. Finally, the chapter considers djent’s position as a subgenre within modern metal music and evaluates, with reference to the critical reception literature, the debates that persist concerning its legitimacy within metal.

This chapter describes how relationship scientists conduct research to answer questions about relationships. It explains all aspects of the research process, including how hypotheses are derived from theory, which study designs (e.g., experiments, cross-sectional studies, experience sampling) best suit specific research questions, how scientists can manipulate variables or measure variables with self-report, implicit, observational, or physiological measures, and what scientists consider when recruiting a sample to participate in their studies. This chapter also discusses how researchers approach questions about boundary conditions (when general trends do not apply) and mechanisms (the processes underlying their findings) and describes best practices for conducting ethical and reproducible research. Finally, this chapter includes a guide for how to read and evaluate empirical research articles.

The Introduction sets out how the number of forcibly displaced persons in the world is the highest ever recorded. Violence associated with armed conflict has become the main cause of forced displacement in the twenty-first century and most refugees are fleeing armed conflicts. Most asylum seekers in the European Union (EU) originate from Syria, Afghanistan and Iraq. However, there are many misconceptions whether persons fleeing armed conflicts are refugees as defined by the Refugee Convention. This book is thus an enquiry into the continued relevance of the Refugee Convention and examines the extent to which asylum appellate authorities in the EU take into account the changing nature of contemporary armed conflicts. The book also explores how the Refugee Convention may be interpreted in a manner that better responds to the changed nature of contemporary armed conflicts from a gender perspective, thus reconceptualising the concept of the refugee. The Introduction sets out the conceptual notions adopted in the book, such as the importance of distinguishing between violence and armed conflicts, the research methodology and sampling of 320 asylum appeal decisions from Belgium, Denmark, France, the Netherlands, Spain and the UK. Finally, it sets out the structure of the book.

How do people judge the sizes of things? What determines people’s evaluations of quantities such as prices or wages? People’s judgements and evaluations are typically relative; the same quantity will be judged or evaluated differently when it appears in different comparison samples. This chapter describes a simple psychological account – the Decision by Sampling model – of how sample-based judgements and evaluations are made. According to the model, what matters is the relative ranked position of an item within a comparison sample. For example, an income of $50,000 a year will be evaluated more favourably within a context of four lower and two higher incomes than in relation to one higher and five lower incomes. According to Decision by Sampling, estimates of the relative ranked position of items within comparison contexts are made by simple sampling and ordinal comparison processes. These estimates are assumed to underpin choice and valuation. The chapter reviews the Decision by Sampling model, relates it to other models such as Adaptation Level Theory and Range Frequency Theory, and shows how it can explain the shape of utility curves and probability weighting functions. The relation of coding efficiency to rank-based models is also discussed.

Sequential decisions from sampling are common in daily life: we often explore alternatives sequentially, decide when to stop such exploration process, and use the experience acquired during sampling to make a choice for what is expected to be the best option. In decisions from experience, theories of sampling and experiential choice are unable to explain the decision of when to stop the sequential exploration of alternatives. In this chapter, we propose a mechanism to inductively generate stopping decisions, and we demonstrate its plausibility in a large and diverse human data set of the binary choice sampling paradigm. Our proposed stopping mechanism relies on the choice process of a theory of experiential choice, Instance-Based Learning Theory (IBLT). The new stopping mechanism tracks the relative prediction errors of the two options during sampling, and stops when such difference is close to zero. Our results from simulation are able to accurately predict human stopping decisions distributions in the dataset. This model provides an integrated theoretical account of decisions from experience, where the stopping decisions are generated inductively from the sampling process.

We describe three sampling models that aim to cast light on how some design features of social media platforms systematically affect judgments of their users. We specify the micro-mechanisms of belief formation and interactions and explore their macro implications such as opinion polarization. Each model focuses on a specific aspect of platform-mediated social interactions: how popularity creates additional exposure to contrarian arguments; how differences in popularity make an agent more likely to hear particularly persuasive arguments in support of popular options; and how opinions in favor of popular options are reinforced through social feedback. We show that these mechanisms lead to self-reinforcing dynamics that can result in local opinion homogenization and between-group polarization. Unlike nonsampling-based approaches, our focus does not lie in peculiarities of information processing such as motivated cognition but instead emphasizes how structural features of the learning environment contribute to opinion homogenization and polarization.

Research into evaluative learning has focused almost exclusively on passive learning. That is, this research tradition is built on paradigms that minimize participants’ autonomy to exert control over the stimuli they learn about at a certain point in time. These paradigms thereby neglect the individuals’ preparedness to process certain information, although evidence is accumulating that individuals are not merely passive recipients of information but that they enrich stimuli with self-generated information. Moreover, in their daily lives, individuals have plenty of opportunities to create their own learning environments. This chapter first provides a definition of preparedness that embraces a constructivist view on evaluative learning. We then review the method and results of a recently developed sampling approach to evaluative learning and relate our findings back to our definition of preparedness. We show that the sampling approach to evaluative learning generates intriguing new findings and a variety of relevant questions for future research.

People revisit the restaurants they like and avoid the restaurants with which they had a poor experience. This tendency to approach alternatives believed to be good is usually adaptive but can lead to a systematic bias. Errors of underestimation (an alternative is believed to be worse than it is) will be less likely to be corrected than errors of overestimation (an alternative is believed to be better than it is). Denrell & March (2001) called this asymmetry in error correction the “Hot Stove Effect.” This chapter explains the basic logic behind the Hot Stove Effect and how this bias can explain a range of judgment biases. We review empirical studies that illustrate how risk aversion and mistrust can be explained by the Hot Stove Effect. We also explain why even a rational algorithm can be subject to the same bias.
