AbstractThis special issue brings together research that reflects on the status and role of different types of language attitudes, and the methods required to study them. Many linguists distinguish between explicit and implicit attitudes towards language, but more often than not it remains unclear how these constructs are defined, and what their potential significance is for the study of language variation and change. The contributions to this issue address this question by critically reflecting on theory and methodology, by highlighting (and clarifying) the terminological confusion, and by showcasing new methods and tools. It is hoped that this special issue can inspire theoretical and methodological convergence in a notoriously fragmented field, so that attitude researchers can identify the underlying structure of language attitudes, and the theoretical significance of language evaluation to processes of language variation and change.

Welding, joining, and coating of metallic materials are among the most applicable fabrication processes in modern metallurgy. Welding or joining is the manufacture of a metal one-body workpiece from several pieces. Coating is the process of production of metallic substrate with required properties of the surface. A long list of specific techniques is studied during schooling and applied in industry; several include resistant spot, laser or friction welding, micro arc oxidation (MAO), chemical vapor deposition (CVD), and physical vapor deposition (PVD), among others. This Special Issue presents 21 recent developments in the field of welding, joining, and coating of various metallic materials namely, Ti and Mg alloys, different types of steel, intermetallics, and shape memory alloys.

During the last century, networks of several types have been used to model a wide range of physical, biological and social systems. For example, Moreno (1934) studied social networks with multiple types of ties, later called multiplex networks (Verbrugge, 1979; Minor, 1983; Lazega & Pattison, 1999) as well as networks with multiple types of actors. Networks with multiple types of actors and relational ties have often been used together: relevant examples are the extensions of two-mode networks studied by Wasserman & Iacobucci (1991), multi-level networks (Lazega & Snijders, 2016), and heterogeneous information networks (Sun et al., 2012). More recently, researchers in physics and computer science have developed models for different types of interconnected networks known as networks of networks (Buldyrev et al., 2010; D'Agostino & Scala, 2014), multilayer social networks (Magnani & Rossi, 2011), and interconnected networks (Dickison et al., 2012).

This essay, and the special issue it introduces, seeks to explore leadership in a post-truth age, focusing in particular on the types of narratives and counter-narratives that characterize it and at times dominate it. We first examine the factors that are often held responsible for the rise of post-truth in politics, including the rise of relativist and postmodernist ideas, dishonest leaders and bullshit artists, the digital revolution and social media, the 2008 economic crisis and collapse of public trust. We develop the idea that different historical periods are characterized by specific narrative ecologies, which, by analogy to natural ecologies, can be viewed as spaces where different types of narrative and counter-narrative emerge, interact, compete, adapt, develop and die. We single out some of the dominant narrative types that characterize post-truth narrative ecologies and highlight the ability of language to ‘do things with words’ that support both the production of ‘fake news’ and a type of narcissistic leadership that thrive in these narrative ecologies. We then examine more widely leadership in post-truth politics focusing on the resurgence of populist and demagogical types along with the narratives that have made these types highly effective in our times. These include nostalgic narratives idealizing a fictional past and conspiracy theories aimed at arousing fears about a dangerous future.

Abstract This introduction provides an overview of this special issue on ‘Regional Platforms’, presenting its background, significance, purpose, and overall structure. To characterize the regional implications in platforms, we first define the concept of ‘platform’ by outlining its basic typology. We define three different types of platforms: product-technology type, content-platforms, and transaction-type. Each of the three designates a different meaning of the term platform and describes a different configuration of platforms in relation to media studies. Challenging the dominant mode of platform studies that presume a global geography for us-based examples, this special issue purposely situates our typology of platforms in regional terms. We argue that digital platforms have given rise to a sense of media regionalism and a renewed regional media geography through both transnational and transmedial processes. The five essays composing this issue are then summarized to demonstrate how the authors approach the question of the regionality of platforms.

With a view to providing contextual background for the Special Issue, this opening article analyses several dimensions of ‘The end of International Relations theory?’ It opens with a consideration of the status of different types of theory. Thereafter, we look at the proliferation of theories that has taken place since the emergence of the third/fourth debate. The coexistence and competition between an ever-greater number of theories begs the question: what kind of theoretical pluralism should IR scholars embrace? We offer a particular account of theoretical engagement that is preferable to the alternatives currently being practised: integrative pluralism. The article ends on a cautiously optimistic note: given the disciplinary competition that now exists in relation to explaining and understanding global social forces, International Relations may find resilience because it has become theory-led, theory-literate and theory-concerned.

Abstract This introduction to the Special Issue on Networked Emotion and Stancetaking summarizes the individual and collective contribution of the included five research articles. We argue for the relevance of discourse-pragmatic theories, methods, and concepts for furnishing cross-disciplinary perspectives into the study of emotion online. Such perspectives are arguably needed in order to clarify the intricate connections between (re)presentations of emotion online and changing practices of news-making and news consumption, story sharing and participation, and public stancetaking in social media and beyond. We propose that empirical analyses of networked practices of stancetaking – epistemic, affective, or narrative – can pinpoint the construction and dissemination of different types of participant positions and stances, including multimodal ones, as well as the creation and uptake of specific frames for interpreting events and crises affectively.
