While supply chain scholars have made considerable progress in theory building and testing, there has been a relative dearth of middle range theory. Middle-range theory (MRT) is context-specific conceptualization providing theoretically grounded insights readily applicable to an empirical context. It promotes rigorous and relevant research, bridges practice and theory, and conveys deeper understanding of how and why phenomena occur. The lack of significant MRT is surprising given the considerable efforts supply chain scholars exert to stay grounded in industry practices. As a result, we put forth a broad call for more middle-range theorizing and provide guidance on how supply chain scholars may meet this call. Specifically, we describe a MRT lever—theoretical contextualization—that strikes a balance between theory and industry and then present two overarching strategies (bottom-up and top-down) for MRT development. We discuss these strategies in the supply chain domain and identify how middle-range theorizing may be undertaken in four emerging, yet important, topics.

This article is based on my presidential address delivered in Baltimore at the 2018 annual meeting of the Eastern Sociological Society. In it, I explore the ways in which theories of the middle-range help us advance sociology as a social science at a time when many express concern about the fragmentation of the discipline.

Using field experiments, scholars can identify causal effects via randomization while studying people and groups in their naturally occurring contexts. In light of renewed interest in field experimental methods, this review covers a wide range of field experiments from across the social sciences, with an eye to those that adopt virtuous practices, including unobtrusive measurement, naturalistic interventions, attention to realistic outcomes and consequential behaviors, and application to diverse samples and settings. The review covers four broad research areas of substantive and policy interest: first, randomized controlled trials, with a focus on policy interventions in economic development, poverty reduction, and education; second, experiments on the role that norms, motivations, and incentives play in shaping behavior; third, experiments on political mobilization, social influence, and institutional effects; and fourth, experiments on prejudice and discrimination. We discuss methodological issues concerning generalizability and scalability as well as ethical issues related to field experimental methods. We conclude by arguing that field experiments are well equipped to advance the kind of middle-range theorizing that sociologists value.

During the past decade, social mechanisms and mechanism-based explanations have received considerable attention in the social sciences as well as in the philosophy of science. This article critically reviews the most important philosophical and social science contributions to the mechanism approach. The first part discusses the idea of mechanism based explanation from the point of view of philosophy of science and relates it to causation and to the covering-law account of explanation. The second part focuses on how the idea of mechanisms has been used in the social sciences. The final part discusses recent developments in analytical sociology, covering the nature of sociological explananda, the role of theory of action in mechanism-based explanations, Merton's idea of middle-range theory, and the role of agent-based simulations in the development of mechanism-based explanations.

PurposeThis paper aimed to analyze the ways in which Niklas Luhmann's theory of the functional differentiation of society can be applied to historical studies. To achieve this, a semantic analysis of the development of modern insurance in Germany during the nineteenth century was conducted.Design/methodology/approachThrough an examination of the significant features of Luhmann's theoretical frameworks in empirical objects, Luhmann's semantic analysis was reformulated as an approach based on a middle-range theory, similar to that of Robert K. Merton, where the potential of the theory can be maximized for empirical research. This paper embodies this proposal, citing several developments within organizations that imbued insurance technology with various ideas and values.FindingsThe theory of the functional differentiation of society can be reconstructed as a working hypothesis from a methodological perspective, instead of a general theory that explains every part of society. Applying this to empirical social practices leads to progress in historical studies conducting the semantic variations connected to the institutional formation and their boundary works.Originality/valueThis paper provides a practical research perspective for historical studies in the social sciences, employing a reinterpretation of sociological theory that may be understood only as a structural presupposition of modern society. Furthermore, the increased possibility of historical-comparative studies on modern insurance is indicated by illustrating the applicability of this framework to a detailed case study of modern insurance.

This paper argues for the development of ‘network political ecology’, drawing on the insights from regional political ecology and recent advancements in network theories of scale, to meet the challenges of investigating the meso-scale problem of vulnerability and adaptation to climate change. ‘Network political ecology’, attentive to scale as socio-ecologically produced and grounded in a regional resource use system, is one such approach that fills this gap in middle-range theory necessary to understand the complex processes through which vulnerability manifests and adaptive capacity is produced. This method is exemplified through the case of groundwater-dependent irrigating farmers in Rajasthan, India.

I review several bodies of empirical urban theory relevant to the archaeological analysis of ancient cities. Empirical theory is a type of \"middle-range theory\" (following Robert Merton): sets of concepts and methods that are less abstract, and have greater empirical content, than high-level social theory. The categories of theory reviewed here include environment-behavior theory, architectural communication theory, space syntax, urban morphology, reception theory, generative planning theory, normative theory, and city size theory. Most of these approaches originated in the fields of architecture, planning, and geography, and they directly link the urban-built environment to the actions of people within cities.

Archaeological predictive modeling has been used successfully for over 20 years as a decision-making tool in cultural resources management. Its appreciation in academic circles however has been mixed because of its perceived theoretical poverty. In this paper, we discuss the issue of integrating current archaeological theoretical approaches and predictive modeling. We suggest a methodology for doing so based on cognitive archaeology, middle range theory, and paleoeconomic modeling. We also discuss the problems associated with testing predictive models.

Background Reports of nursing research often do not provide adequate information about whether, and how, researchers applied theory when conducting their studies. Unfortunately, the lack of adequate application and explication of theory in research impedes development of knowledge to guide nursing practice. Objectives To clarify and exemplify how to apply theory in research. Methods First we describe how researchers can apply theory in phases of research. Then we share examples of how three research teams applied one theory to these phases of research in three different studies of preventive behaviors. Conclusions Nurse researchers can review and refine ways in which they apply theory in guiding research and writing publications. Scholars can appreciate how one theory can guide researchers in building knowledge about a given condition such as preventive behaviors. Clinicians and researchers can collaborate to apply and examine the usefulness of theory. Clinical Relevance If nurses had improved understanding of theory‐guided research, they could better assess, select, and apply theory‐guided interventions in their practices.

PurposeThe research examines the simultaneous processes of value co-creation and value co-destruction in the implementation of a mobile banking application in rural Colombia. Rural communities experience digital and financial deficits and often become the object of technology-based initiatives. In the town, vulnerable female heads of household received a government subsidy through a mobile app, becoming an experimental group for this government–private bank collaboration. In an effort to create the first cashless society in Colombia, the bank engaged the entire town and local government to create a service ecosystem, constituted by operant resources.Design/methodology/approachThis study uses a qualitative, ethnographic approach to investigate the experiences of stakeholders in engaging with a mobile banking app. The empirical data is drawn from 34 interviews, representing different layers of this service ecosystem. The study identified and analysed actor engagement behaviours that occurred in the micro-, meso-, macro- and meta-layers of this ecosystem that shaped the perception and usage of mobile payments and digital money for rural consumers.FindingsThe study found that simultaneous manifestations of the co-creation and co-destruction of value present in different layers ultimately diminished the value proposition for this digital money system. We shed light on how actor engagement transitions across different layers of the ecosystem and that negative interactions in the meta-layer of the ecosystem can affect perceptions of value in the micro-layer.Originality/valueThis study has contributed to the service literature by integrating epistemological cultural theory into value co-creation and co-destruction construct. In doing so, we provide a broader context for understanding how actor engagement can negatively impact on the value creation process and offer a meaningful contribution to the development of midrange theory of the value creation process.
