An empirical social networks study is concerned with what a well-defined social network is like, and whether and how it matters in some context of interest. Designing a successful one requires serious thinking on the front end about what the network is and what it does in theory. This book aims to help researchers do just that. To begin, this chapter motivates this research area with examples from political science, explains why the topic is unique enough to warrant a whole book, and offers guidance on how to know if your research should incorporate networks.

As we discussed with regard to leadership in Part 1, the context in which the public health tools are used has a bearing on the choice of tool and how it is implemented. In the second part of Essential Public Health: Theory and Practice, we consider a range of contemporary contexts in which public health is practised and illustrate how the tools we have described are applied.

Informal borrowings constitute an important linguistic phenomenon, yet they remain underrepresented in scholarly literature. This book is to remedy the situation. Drawing from the methodological framework of documentary linguistics and sociolinguistics, it relies on lexical material from a large database of citations from diverse sources – including spoken utterances, films and TV shows, print, and social media – to ensure authenticity and representativeness. Much space is devoted to the presentation, explanation, interpretation, and illustration of language data; the format of description is designed to be extensive, covering a wide range of themes which allow an examination from various perspectives. The description is amply supported throughout the text with usage examples that illustrate linguistic patterns, show the sociocultural context in which they are used, and attest to the very existence of these expressions.

Chapter 13 opens by asking readers to look at a bubble chart showing numbers of native speakers of various languages, then to describe the figure in words, and finally to compare these visual and verbal ways of conveying information about speakers. The chapter encourages demonstrations that start with memorable and fun examples, emphasizing that the free-choice setting means people can walk away if they are not immediately intrigued. Again, research articles can be mined for classic phenomena. The chapter also exemplifies several ways of giving people something to talk about: Using one’s own body can launch demonstrations of speech articulation. Special hardware or software can launch demonstrations of speech acoustics. Video such as fMRI of arias and beatboxing can catch people’s attention and start the desired conversations. Pictures and objects that can be handled, as well as games and puzzles such as tongue twisters, are a rich ground for juicy questions. The Worked Example shows different ways to build a demonstration with the Stroop task, interactive with low-tech or high-tech support. Giveaway materials are also emphasized as making a demonstration memorable and fun.

In a striking passage from the last book of his Tusculan Disputations, Cicero claims to live from day to day (nos in diem vivimus; 5.33). He always opts for what he deems probable, and this, he argues, also constitutes his freedom. This remarkable statement, which is obviously rooted in Cicero’s Academic philosophy, is far from unproblematic. This contribution aims at a better understanding of Cicero’s claim, through an analysis of his argumentative strategies in Tusculan Disputations. More precisely, attention is given to Cicero’s use of (1) the argument from common sense, (2) the argument from dignitas and decorum, (3) illustrative examples, and (4) to his approach in introducing the philosophical topics of the conversation. Finally, I deal with the complicated question as to whether Cicero’s sophisticated attitude of in diem vivere can be reconciled with the therapeutic goal of Tusculan Disputations.

We present several examples that show boundaries of the results obtained in previous chapters.

This chapter discusses how innovations are reshaping the two major fundamental strategic options that a shipowner typically might have: asset-play, i.e., a typically short-term focus on “in-out/long-short”, vs. industrial shipping, i.e. more tailored ships employed on longer-term charters, and typically with relatively high financial gearing. Key innovations are reshaping the essence of each of these strategic options, above all, regarding what might now be a commercially modern ship. Customer closeness is increasingly seen as key to all of this.
