New Framework

Civilian control of the military is a fundamental attribute of democracy. While democracies are less coup-prone, studies treating civilian control as a dependent variable mostly focus on coups. In this paper, I argue that the factors predicting coups in autocracies, weaken civilian control of the military in democracies in different ways. To capture this difference, I advance a new comprehensive framework that includes the erosion of civilian control by competition, insubordination, and deference. I test the argument under conditions of an intrastate conflict—a conducive environment for the erosion of civilian control. A large-N analysis confirms that while intrastate conflict does not lead to coups in democracies, it increases the military’s involvement in government, pointing to alternative forms of erosion taking place. Further case study—Russia’s First Chechen War—demonstrates the causal logic behind the new framework, contributing to the nuanced comparative analysis of civil-military relations across regimes.

This article reports the results of a nested analysis conducted to evaluate whether or not electoral donations are considered legal bribes. Introduced by Lieberman, nested analysis brings together the strengths of the regression analysis and the case study research by integrating large- N approaches (LNA) with small- N approaches (SNA). The nested analysis uses a sequential sampling model (QUANTITATIVE → QUALITATIVE) and a nested sampling design (case selection “on/off the line”). Here, Lieberman’s original model was extended to deal with an apparent paradox that emerged from the analysis. This inquiry included a cross-national examination among 78 countries, denoted as LNA, followed by an intranational analysis conducted in Colombia, where an SNA survey with 302 respondents and an SNA case study were carried out.

The Comparative Study

This article considers the role of generalization in comparative case studies, using as exemplars the contributions to this special issue on climate change politics. As a research practice, generalization is a logical argument for extending one’s claims beyond the data, positing a connection between events that were studied and those that were not. No methodological tradition is exempt from the requirement to demonstrate a compelling logic of generalization. The article presents a taxonomy of the logics of generalization underlying diverse research methodologies, which often go unstated and unexamined. I introduce the concept of resonance groups, which provide a causeway for cross-system generalization from single case studies. Overall the results suggest that in the comparative study of complex political systems, case study research is, ceteris paribus, on par with large-N research with respect to generalizability.

The Strategic Use of Women Candidates in Post-Scandal Environments

Chapter 4 examines the inclusion calculations of party elites in the aftermath of a massive corruption scandal. It argues that party elites have an incentive to strategically increase the presence of women candidates in such an environment in order to associate themselves and their party with stereotypical feminine traits, but this incentive is not always enough to trigger inclusion. Case study analyses of Spain, Portugal, and Ireland are presented, with evidence that political parties in Spain and Portugal recruit and run more women candidates in high-profile positions after a massive scandal breaks but, due to the high “costs” of running women in the institutional environment of Ireland, this effect is not found there. Finally, the chapter presents a large-N regression analysis of legislative electoral results over a period of 20 years, with evidence that more women win legislative seats in the aftermath of a corruption scandal.

The Web

In the era of computing, where the data are stored in a cloud or distributed environment, the privacy of data is one of the challenging tasks. The attacks like denial of service attacks (DoS), insider attack compromised the security of the system. In this chapter, the authors discussed a blockchain-based database, where data are encrypted and stored. The Web API is used as an interface for the storage and sharing of data in the blockchain system. There are several types of attacks that are performed by the adversary on the database to destroy the vulnerability of the system. Here, the authors are mainly focused on the SQL injection attack which is performed by the adversary on Web API. To cope with this problem, they present the case study based on the Snort and Moloch for automated detection of SQL attack, network analysis, and testing of the system.

This chapter explores the degree to which an expectations approach can help us make sense of the seemingly contradictory findings of the large-N quantitative research that has dominated the study of interdependence and war over the last two decades. It also lays out a new approach to qualitative historical analysis for rare events research—one that minimizes the problems of selection bias and generalizability by covering the essential universe of cases for a chosen period of time. Additionally, the chapter discusses how qualitative research can help overcome the limitations of quantitative methods in the measuring of leader expectations about the future.
