Abstract

Purpose

The purpose of this paper is to present a new numerical model for shallow water flows over heterogeneous sedimentary layers. It is already several years since the single-layered models have been used to model shallow water flows over erodible beds. Although such models present a real opportunity for shallow water flows over movable beds, this paper is the first to propose a multilayered solver for this class of flow problems.

Design/methodology/approach

Multilayered beds formed with different erodible soils are considered in this study. The governing equations consist of the well-established shallow water equations for the flow, a transport equation for the suspended sediments, an Exner-type equation for the bed load and a set of empirical equations for erosion and deposition terms. For the numerical solution of the coupled system, the authors consider a non-homogeneous Riemann solver equipped with interface-tracking tools to resolve discontinuous soil properties in the multilayered bed. The solver consists of a predictor stage for the discretization of gradient terms and a corrector stage for the treatment of source terms.

Findings

This paper reveals that modeling shallow water flows over multilayered sedimentary topography can be achieved by using a coupled system of partial differential equations governing sediment transport. The obtained results demonstrate that the proposed numerical model preserves the conservation property, and it provides accurate results, avoiding numerical oscillations and numerical dissipation in the approximated solutions.

Originality/value

A novel implementation of sediment handling is presented where both averaged and separate values for sediment species are used to ensure speed and precision in the simulations.

Abstract

Purpose

The purpose of this paper is to descriptively characterize the demographic profiles of entrepreneurship educators (EE) in US community colleges, and include descriptive and inferential examination of their pedagogical modalities, attitudes toward online modality, and use of teaching materials, tools and techniques, with resulting impacts and outcomes on students.

Design/methodology/approach

This paper analyzed data collected by the National Association for Community College Entrepreneurship on the national landscape of community college entrepreneurship education. The useable sample included 568 responding participants from 270 US community colleges, all of whom self-identified as faculty members who teach entrepreneurship. To enhance the understanding of the findings, a small panel of EE experts was solicited to offer perspective and future study suggestions.

Findings

Ten distinct findings are offered. These include EE teaching materials, teaching modalities, use of e-learning and alternative techniques, and their relation to modalities; and examination of five distinct entrepreneurial educational outcomes and their relationship to educator use of pedagogical materials, tools and techniques.

Originality/value

Understanding effective entrepreneurship educational practices is important to globally advancing entrepreneurship education. This paper concentrates on the profiles and practices of educators in the significant but under-researched domain of US community colleges, and offers an incremental contribution and awareness of effective entrepreneurship education teaching methods.

Abstract

Volumes 70 and 71 of Research in the Sociology of Organizations combine to comprise cutting edge theory and empirical scholarship at the interface of practice and institution in organization studies. As we highlight, this interface has spurred particularly generative conversations with many open questions, and much to explore. We provide a review of scholarly developments in practice theory and organizational institutionalism that have given rise to this interest in building a bridge between scholarly communities. As signaled by recent efforts to construct a practice-driven institutionalism, we highlight how connecting practice theory with the institutional logics perspective provides a particularly attractive focal point for scholarship at this interface due to a variety of shared ontological and epistemological commitments, including the constitution of actors and their behavior. Collectively, the papers assembled unlock exciting opportunities to connect distinct, but related scholarly communities on practice and institution, seeding scholarship that can advance our understanding of organizational and societal dynamics.

Abstract

My intent in this chapter is not to review this ever-expanding body of work, which now encompasses all sorts of “new” institutionalisms applied to micro-, meso-, and macro-levels of social analysis in a wide variety of fields. Rather, I propose to stay a narrower course, focusing on the “new” organizational institutionalism that emerged at Stanford in the 1970s. To a considerable extent, this focus excludes from sustained attention the growth of world polity theory, a body of work that is closely aligned to organizational institutionalism, but that was developed somewhat independently of Scott by Meyer and his associates (for an excellent, short overview of this line of work, see Jepperson, 2002; otherwise, see Meyer et al., 1997 or Meyer, 2000). In focusing on organizational institutionalism, I will add only marginally to what has already been written. My first task will be to describe the earliest developments of this form of analysis in the 1970s and early 1980s at Stanford, since describing how research programs in organizational studies got founded at Stanford is a major theme of the present volume. After that, I will advance some ideas about how and why this research program became so influential, in so many fields of study.

Abstract

I am honored to contribute to this volume on the Stanford Organization Theory Renaissance, though I must admit that I am a bit sheepish about being listed as a faculty member. I was indeed on the Stanford faculty, from 1997 to 2001. However, the experience for me was more of a developmental one in which I learned from my colleagues, who consisted of the leading lights in the sociology of organizations and organization theory generally. This period was as formative for me as was the prior period, when I was a student in the formal sense. I find it easy to point to specific ideas that I encountered during my stay at Stanford and to trace how they shaped my perspective on key questions of social and economic organization. In the following, I will discuss one example of this Stanford influence. In particular, I build on ideas developed at Stanford during the 1970s and 1980s (and which I came to appreciate during the 1990s) to make progress on a puzzle that did not occupy center stage there and then. Nothing testifies to the value of a theory or approach than its ability to generate insight well beyond the original questions for which it was originally developed.

Abstract

The growing interest in the microfoundations of institutions is a significant, yet surprising development given that the theoretical tradition’s original insight was to account for macro, institutional influences on lower-level units. The call for microfoundations has gone on without really clarifying what institutionalists mean by microfoundations. Some reflections on the usefulness or purpose of establishing the microfoundations of institutional theory are in order. The authors advocate for treating the micro as part of pluralistic and multi-level accounts of institutional processes. Central is the conceptualization of actors as more or less institutionalized identities and roles.

Abstract

Recent research develops theory and evidence to understand how organizations come to be seen as “actors” with specified features and properties, a core concern for phenomenological institutionalism. The authors use evidence from changes in research designs in the organizational study of institutional logics as an empirical strategy to add fresh evidence to the debates about the institutional construction of organizations as actors. The case is the research literature on the institutional logics perspective, a literature in which organizational and institutional theorists grapple with long-time social theory questions about nature and context of action and more contemporary debates about the dynamics of social orders. With rapid growth since the early 1990s, this research program has elaborated and proliferated in ways meant to advance the study of societal orders, frames, and practices in diverse inter- and intra-organizational contexts. The study identifies two substantive trends over the observation period: A shift in research design from field-level studies to organization-specific contexts, where conflicts are prominent in the organization, and a shift in the conception of logic transitions, originally from one dominant logic to another, then more attention to co-existence or blending of logics. Based on this evidence, the authors identify a typology of four available research genres that mark a changed conception of organizations as actors. The case of institutional logics makes visible the link between research designs and research outcomes, and it provides new evidence for the institutional processes that construct organizational actorhood.

Abstract

Teacher effectiveness and teacher quality have become the focus of intense international attention and national concern. Dozens of nations are implementing a diverse set of strategies that aim to improve the quality of education by improving the quality of teachers. These efforts have not been well coordinated, and as the authors in this volume show, core constructs of quality have not been well defined. In this introductory chapter, we discuss why teachers are now “under the microscope” of policymaker’s attention and elaborate how the chapters in this volume identify particularly fruitful avenues for further study. The assembled chapters address two complex questions: (1) what existing cross-national measures of teacher effectiveness and teacher quality are most promising and how can these be aligned to maximize their research potential? and (2) what core constructs of teacher quality or effectiveness are missing from the evidence-base, and how can cross-national comparative research help refine these? To investigate these questions, the chapters in this volume address different aspects of “quality.” While quality may be politically contested, there is a significant need to continue to articulate a truly global perspective on teacher quality. The authors look at a wide range of aspects of quality in order to advance thinking about teacher education, instructional quality and workforce or organizational conditions that affect quality; to analyze instruments, tools, or measures used to assess quality; and identify what measures need to be developed further. We also note how scholarly study of the spread of transnational teacher reforms has failed to keep pace with national policy changes regarding teacher quality, and advance a more general theory of the forces affecting national policymakers.
