We propose a risk factor for idiosyncratic entropy and explore the relationship between this factor and expected stock returns.

Abstract

Purpose

We propose a risk factor for idiosyncratic entropy and explore the relationship between this factor and expected stock returns.

Design/methodology/approach

We estimate a cross-sectional model of expected entropy that uses several common risk factors to predict idiosyncratic entropy.

Findings

We find a negative relationship between expected idiosyncratic entropy and returns. Specifically, the Carhart alpha of a low expected entropy portfolio exceeds the alpha of a high expected entropy portfolio by −2.37% per month. We also find a negative and significant price of expected idiosyncratic entropy risk using the Fama-MacBeth cross-sectional regressions. Interestingly, expected entropy helps us explain the idiosyncratic volatility puzzle that stocks with high idiosyncratic volatility earn low expected returns.

Originality/value

We propose a risk factor of idiosyncratic entropy and explore the relationship between this factor and expected stock returns. Interestingly, expected entropy helps us explain the idiosyncratic volatility puzzle that stocks with high idiosyncratic volatility earn low expected returns.

Abstract

Purpose

To describe a way of teaching industrial ecology (IE) and to show some tools that may help for the IE teaching.

Design/methodology/approach

In the paper, the development of lectures, practical lessons and projects on real industrial ecosystems are described. Also the teaching materials used are described.

Findings

The presented methodology for teaching IE has been a good means for the understanding of the IE concept. Some of the educational tools presented have helped the students to increase their awareness of the distance between IE and the real industrial field, discover that there are a lot of by‐product exchange possibilities between industries, to develop their creativity, to connect the theory to practice in the industrial systems and have encouraged them to try to put the IE ideas into practice. This methodology has been useful for either small or big groups and for people with either the same or very different backgrounds. And it has been observed that the quality of the work is enhanced when the members of the group have different backgrounds.

Practical implications

The paper shows methodologies and tools that may encourage and help other teachers/professors to use them in their IE lessons. It may also help IE researches to know which real examples and methodologies help students to understand IE concept. This could encourage them to develop projects and research in those directions.

Originality/value

The paper fulfils the need of knowing real experiences in IE teaching and their results. And in special, experiences that have been tested for a long period of time and with a great number of students. All the experiences described in the paper have been created and put into practice by the author.

Abstract

Purpose

Research on Islamic entrepreneurship (IE) is growing but with difficulty. After reviewing six IE models, several problematic inconsistencies were identified, which can be categorized into three: sporadic objectives of IE, diverging core components and inconsistent levels of analysis. This study aims to articulate a synthesized IE model.

Design/methodology/approach

An Islamic critical realist synthesis is used by combining six IE models and situating them within an Islamic system of governance. Specifically, the Islamic governance conceptual matrix is used to offer an objective template.

Findings

A synthesized model of IE within an Islamic system of governance comprises the following: the objectives of IE are not to be confined to only financial sustainability, but to achieve all five Maqās.id of the Sharī’ah (i.e. preservation and promotion of faith, life, intellect, posterity and wealth); models of IE should cover the individual, group, organizational, societal, state and international levels for comprehensiveness; tawhīd is crucial to distinguish between IE and conventional entrepreneurship; halal IE activities can be further categorized into obligatory, recommended, permissible and reprehensible; Islamic values are to be differentiated from cultural values; and both Islamic and cultural values shape IE and vice versa.

Research limitations/implications

Limited number of models of IE were included in this synthesis. Although the resulting synthesized model is extensive, additional models of IE can be built to extend or even challenge it.

Originality/value

A novel model of IE within an Islamic system of governance is presented.

Abstract

Purpose

The purpose of this study is to address the lack of a proper database or finding system for scholars of Islamic economics (IE), as well as the dearth of literature on bibliographic search and trend analyses of scholars in this field. This study aims to adopt a bibliometric review of the bibliography of experts in IE and scholars in disciplines allied to IE.

Design/methodology/approach

This study adopts a bibliometric review of the bibliography of experts in IE and scholars in disciplines allied to IE. The researchers collected data on scholars’ profiles and scholarly works and analyzed them to identify trends and patterns.

Findings

This study presents two main themes: the profiles of the scholars in IE and allied disciplines, and their scholarly works. The findings on the scholars’ profiles reveal that most scholars are contemporaries born between the 1940s and 1990s, concentrated in Malaysia and affiliated with the International Islamic University Malaysia. Regarding their scholarly works, the majority of their efforts resulted in 11,736 materials in the form of books, articles and conference papers spread across 13 sub-areas in IE.

Originality/value

This study fills the gap in literature by providing a database and finding system for scholars in IE and conducting a bibliographic search and trend analysis of scholars in this field. The findings shed light on the profiles of scholars and their scholarly works, which can guide future research in this area.

Abstract

In this chapter, I highlight the need to turn the institutional ethnography (IE) lens of enquiry onto IE itself, and consequently, the importance for institutional ethnographers to attend to their standpoint in taking up and activating their understanding of IE. Many, including Wise and Stanley (1990) and Walby (2007), celebrate Smith’s sociology but raise important ontological and epistemological questions about IE’s own recursive power. While IE has developed from a critique of wider sociological inquiry, it is troubled by the institutional ethnographer’s own standpont when using IE uncritically, without reflexivity of their standpoint in relation with IE and knowledge generation. IE stands in relation between the researcher and the everyday of the research participants in a local research context that is particular and plural, situated and dynamic. The chapter highlights a particular critique by Dorothy Smith of Pierre Bourdieu’s concept of habitus as a “blobontology,” yet considers the theoretical similarities between Smith and Bourdieu. I argue that institutional ethnographers and IE itself are not be immune from the kinds of unravelling that Smith undertakes of other approaches to sociological inquiry. Researcher standpoint, reflexivity, and their relation to knowledge generation are therefore critical aspects of approach without which there is potential to “other” and develop morally questionable representations of people that diminishes the actuality of their subjective experience.

Abstract

Institutional ethnography (IE) is a sociology that focuses on the everyday world as problematic. As a theory/method of discovery, it focuses on how the work people do is organized and coordinated by text-mediated and text-regulated social organization. Actor-network Theory (ANT) is a theory/method that is concerned with how realities get enacted. ANT focuses on a multiplicity of human and nonhuman actors (e.g., computers, documents, and laboratory equipment) and how the relations between them are constituted and how they are made to hang together to create certain realities. In this chapter, we discuss some of the similarities and differences between IE and ANT. We begin with an overview of IE and ANT and focus on their ontological and epistemological “shifts.” We then discuss some of the similarities and differences between IE and ANT, particularly from an IE stance. In doing so, we put these approaches into dialog and allude to some of the potential benefits and pitfalls of combining these approaches.

Abstract

Inclusive education (IE) comes to the fore when international development frameworks such as the Education for All (EFA) movement (1990), and, in particular, the Salamanca Statement (1994) are considered. The Statement portrays “mainstreaming” children with disabilities as an integral part of national education plans and asserts that establishing regular schools with inclusive orientation is the most effective means to combat discriminatory attitudes (UNESCO & Ministry of Education and Science, Spain, 1994). This wave has crested worldwide, and Bhutan and Japan are not exceptions. The overall objective of this study is to reexamine socio-cultural dimensions of “IE” by explicating voices on the ground. This chapter describes how IE has been promulgated in the two countries while forming culturally, socially, and locally fitted policies, and documents the dynamics, challenges, and complexities of IE. The results indicate that while both countries followed similar dynamics in the development of IE policies, progressing from “segregation” to “integration” before reaching “inclusion,” different implementation processes have led to divergent forms of IE, and thus the two nations exhibit heterogeneity in their interpretations of IE. Reflecting the voices of local teachers on the ground, the study illustrates the importance of encompassing societal contexts vis-à-vis exploring global issues such as IE.

Abstract

Purpose

This study aims to follow a rigorous approach to identify, critically analyze and synthesize 75 papers published from 2000 to 2022.

Design/methodology/approach

The study presents a systematic literature review on identity expressiveness (IE), clarifying and expanding what is currently known about the concept.

Findings

To synthesize current knowledge on IE, the study uses the overarching framework of antecedents-phenomenon-consequences, using this same framework to identify gaps and future research directions. The findings show individual and brand-related factors such as the need for uniqueness and anthropomorphism as antecedents of IE, and eWOM/WOM, impulse purchases and upgrading to more exclusive lines as consequences of IE.

Research limitations/implications

The study contributes to theory by synthesizing and mapping current understanding of the state of knowledge on the concept of IE while highlighting gaps in the extant literature and paving future research directions for scholars in the field.

Practical implications

The study offers useful insights for practitioners, broadening marketers’ actionable options in identity-based marketing. Marketers can use insights from this study to inform marketing strategy and communication campaigns for different types of brands.

Originality/value

To the best of the authors’ knowledge, this study is the first of its kind and offers an integrative review of the current literature on IE, thus enhancing understanding of the concept, its antecedents and consequences. The study also contributes to knowledge by highlighting future research priorities for researchers in this field of enquiry.

This study aims to examine the potential of Information Ethics (IE) to serve as a coherent ethical foundation for the library and information science profession (LIS profession).

Abstract

Purpose

This study aims to examine the potential of Information Ethics (IE) to serve as a coherent ethical foundation for the library and information science profession (LIS profession).

Design/methodology/approach

This study consists of two parts: the first part present IE’s central theses and the main critiques it has received; the second part offers the authors' own evaluation of the theory from the LIS perspective in two steps: (1) assessing its internal consistency by testing its major theses against each other; (2) assessing its utility for resolving frequently debated LIS ethical dilemmas by comparing its solutions with solutions from other ethical theories.

Findings

This study finds that IE, consisting of an informational ontology, a fundamental ethical assertion and a series of moral laws, forms a coherent ethical framework and holds promising potential to serve as a theoretical foundation for LIS ethical issues; its inclusion of nonhuman objects as moral patients and its levels of abstraction mechanism proved to be particularly relevant for the LIS profession. This study also shows that, to become more solid an ethical theory, IE needs to resolve some of its internal contradictions and ambiguities, particularly its conceptual conflations between internal correctness, rightness and goodness; between destruction, entropy and evil; and the discrepancy between its deontological ethical assertion and its utilitarian moral laws.

Practical implications

This study alerts LIS professionals to the possibility of having a coherent ethical foundation and the potential of IE in this regard.

Originality/value

This study provides a systemic explication, evaluation and field test of IE from the LIS perspective.

Abstract

Microfoundational research increasingly strives to examine the interlinkages between various higher- and lower-level structures. To better capture microfounded change processes, I develop the multi-dimensional concept of institutional entrepreneurs’ skills that defines actors’ abilities to enhance institutional change. By a systematic literature review on institutional entrepreneurship, I identify seven institutional entrepreneurs’ skill dimensions: (i) analytical skills, (ii) empathic skills, (iii) framing skills, (iv) translational skills, (v) organizational skills, (vi) tactical skills, and (vii) timing skills. The established concept provides opportunities for future microfoundational research by examining the formation and the application of the seven skill dimensions.
