Research on how children are affected by their sibship size, i.e., their number of siblings, faces a serious hurdle because sibship size is endogenous in the model. The current “gold standard” method to solve this is to use (parity-specific) twin births as instrumental variables. The purpose of this chapter is twofold. Firstly, it introduces instrumental variable methods in general. Secondly, it a

This article introduces a collection of papers that explore two understudied but critical questions of enduring concern for the study of democratization. Was the secret ballot driven by the same forces that drove the rise of democracy more generally? Did the secret ballot end electoral fraud, or was its effect merely endogenous to economic modernization more generally? This article provides histor

Does increasing income inequality affect outcomes such as obesity, life expectancy and subjective well-being? Are rich and poor groups affected in the same ways? This book reviews the latest research on the relationship between in

This introductory chapter makes the case that despite different epistemological starting points, history and speculative fiction are both arguably “literatures of cognitive estrangement.” Both can help expose invisible problematic aspects of their authors’ and readers’ societies and suggest possible solutions or futures. Summarizing relevant existing literature and theoretical perspectives, the ch

This issue’s articles will offer views into the conditions of nation and nationalism from outside contemporary national­ism studies, or perhaps from a position that straddles the boundaries of the inside and outside of nationalism studies. We hope that they contribute in unexpected ways to focused research – sociological and beyond – on nation­alism, and on nationalism’s and Christianity’s interlo

We describe a laboratory exercise that is designed to give advanced undergraduate students in analytical chemistry a meaningful introduction to biological mass spectrometry. We ask the students to solve a mystery: given two proteins, what are they, and from which animals do they originate? This exercise involves use of two mass spectrometers available in our institution: a fairly basic matrix-assi

Measures of physical integrity rights violations typically focus on abuses by state actors. However, nonstate actors also represent a grave threat to personal security. This article introduces the Societal Violence Scale (SVS) which uses the US State Department Human Rights reports as a basis for developing a new scale of physical integrity rights abuses by nonstate actors to gain a more comprehen
