This paper aims to probe the limits of the empirical-normative divide as a conceptual framework in business ethics.

A systems theory perspective debunks this divide as a false distinction that cannot do justice to the conceptual complexity of the field of corporate social responsibility (CSR) scholarship.

Drawing on the systems-theoretic ideas of Niklas Luhmann and the “Laws of Form” by George Spencer Brown, the paper shows that the divide may be dissected into a four-cell matrix constituted by two other distinctions-descriptive vs prescriptive and categorical vs hypothetical-the latter of which was seminally suggested by Donaldson and Preston (1995).

The emerging four-cell matrix is shown to centrally embrace the multiplicity of normative, empirical and instrumental approaches to CSR. This multiplicity is exemplified by the application of these approaches to the phenomenon of CSR communication.

A more general implication of the proposed argument for the field of business ethics is in tracing the phenomena of moral diversity and moral ambivalence back to the regime of functional differentiation as the distinguishing feature of the modern society. This argument drives home the point that economic operations are as ethical or unethical as political operations, and that both economic and political perspectives on ethical issues are as important or unimportant as are religious, artistic, educational or scientific perspectives.

In contrast to the empirical-normative divide, the perspective is shown to centrally embrace the multiplicity of normative, empirical and instrumental approaches to CSR.

This paper aims to analyze the benefits of the blockchain to the circular economy (CE), which is composed of both closed-loop supply chain (CLSC) systems and reverse omnichannel solutions. By ensuring transparency, traceability, visibility and security, the blockchain allows firms to acquire operational capabilities through a CLSC and service capabilities through a reverse omnichannel, which can boost business performance considerably. The related network of relationships can be reinforced by establishing incentives, which entail both smart contracts in the blockchain and active return approaches in CE.

After identifying the boundaries of the theoretical framework, several research hypotheses are developed according to the literature review and emerging gaps. These gaps link to the impact of the blockchain on CE systems (CLSC and reverse omnichannel), as well as the influence on business performance. The hypotheses are then tested using structural equation modeling and adopting a partial least squares-path modeling technique on a dataset composed of 157 firms. Finally, multigroup analysis is used to test the impact of incentives on the research hypotheses.

The blockchain facilitates a more efficient CE system, although reverse omnichannel solutions seldom bring any benefits to performance. The shift from a passive to an active return approach must be carefully evaluated. The CLSC network can benefit from an active return approach by developing appealing incentives for collectors and enhancing the positive effects of the blockchain. In contrast, consumer incentives can have detrimental effects on the blockchain. Various combinations of incentives can only bring a few business performance increases, while collector incentives are vital to reinforce the CE system's operational and service capabilities.

This paper takes a new approach toward the study of CE, which considers a dual circular system composed of a CLSC and a reverse omnichannel. The research explores whether the adoption of blockchain technology enables better return processes by improving the operations in CLSC and services in reverse omnichannel. Finally, this is the first empirical work to evaluate the benefits emerging from incentives, which can activate smart contracts in the blockchain and enable active return approaches in CE.

This chapter uses Austrian capital theory to illustrate why empirical work can be elusive in typical Austrian themes. It explores the nature of the problem and different alternative solutions to empirical challenges. This chapter also discusses the Austrian literature’s epistemological approach to empirical work to shed light on the controversial relationship between Austrian theory and empirical testing. Finally, this chapter offers examples of how Austrian and mainstream economics can find a common empirical ground.

The purpose of this paper is to review the existing literature on empirical research in lean manufacturing (LM). It provides a critical assessment of empirical research methodology of 178 research articles published from 1990 to 2009.

The article reviewed a set of 178 empirical research articles in LM research with respect to empirical research design and its related facets. The 236 empirical research articles which are published in 70 journals during 1990-2009 are collected from four major management science publishers, namely, Emerald Online, Science Direct, Springer Link and Taylor & Francis. In total 178 research articles published in 24 journals are selected for critical review of empirical research methodology in LM. The approach for the critical review of 178 empirical research articles in LM is based on empirical research approach given by Flynn et al. (1990). The critical review discusses the current status of empirical research in LM and future directions.

It is concluded from the analysis of the results that: the number of empirical research articles in LM is increasing at a faster pace than ever before; theory building and theory verification articles are equally advanced; the researchers have also unexplored various aspects of empirical research such as importance of triangulation of data, alternate research designs other than survey and case studies; contextual focus is mostly on the manufacturing industry; more focus required on other aspects of empirical research such as collecting the samples from developing and undeveloped countries, larger sample size, longitudinal data collection methods. Finally, it concludes that there is a need of LM frameworks, which gives the stepwise process to remove all kinds of wastes from any organization.

To the knowledge of the authors, it is the first of its kind attempt to critically review the empirical research articles in LM. The review analysis entirely focussed on descriptive statistics of empirical research in LM. The sample size is one of the unique features of this research as the number of shortlisted articles is 178 in 24 journals published over a time span of 20 years (1990-2009).

This paper investigates how Information Systems (IS) researchers apply institutional theoretical frameworks. The purpose of this paper is to explore the operationalization of meta-theoretical frameworks for empirical research which can often present difficulties in IS research. The authors include theoretical, methodological and empirical aspects to explore modalities of use and suggest further avenues.

After an overview of institutional concepts, the authors carry out a thematic analysis of journal papers on IS and institutional frameworks indexed in EBSCO and ABI databases from 1999 to 2009. This consists of descriptive, thematic coding and cluster analysis of this textual database, this combined qualitative and quantitative method offers a unique way of analyzing how operationalization is carried out.

The findings suggest three groups of publications which represent different methodological approaches and empirical foci: “descriptive exploratory approaches,” “generalizing approaches,” and “sociological approaches.” The authors suggest that these three groups represent possible patterns of the use of “meta” social theories in IS research, reflecting a search for disciplinary legitimacy. This helps us analyze papers according to how they use and apply theories. The authors identify the “organizing vision” and the regulatory approach as two institutionalist “intermediary” concepts developed by IS researchers. Furthermore, the authors find that institutional theoretical frameworks have been used in “direct,” “intermediary” or “combined” conceptualizations. The authors also confirm the dynamism of the IS institutional research stream, as evidenced by the increase in number of articles between 1999 and 2009, and identify a maturation process of the IS field in investigating a social theory.

The evolution the authors identify in the application of institutional theoretical frameworks in the IS field reveals conformity in methodological, theoretical and empirical terms. By identifying these patterns, it becomes possible to understand institutional reasons for their existence and legitimacy; and to propose other avenues of exploration in future IS research, such as combining different theoretical lenses in institutional frameworks. The methodological contribution is to provide an innovative methodology which helps describe categories and levels of institutional theoretical frameworks used, leading to the identification of gaps and proposing further avenues of research.

The purpose of this study is to evaluate the methods employed for classifying and quantifying the potential of squeezing in tunnels. Along with the empirical and semi‐empirical approaches presently available in order to anticipate the potential of squeezing tunnel problems, the squeezing potential of Karaj water transfer tunnel and North West Tunnel Convey (NWTC) tunnels (Lot 2), located in Iran, are evaluated and presented. Those two case studies have an interesting geology profile and parameters to identify and then evaluate the squeezing potential.

In recent years, there has been an increasing interest in the tunnel construction. This paper describes the squeezing behavior of poor rock mass associated with deformability and strength properties. In Karaj water transfer tunnel, there are eight lithological rock types; and NWTC tunnel (Lot2) has 21 Lithological rock types. The parameters for rock classification, such as rock quality designation (RQD), rock mass rating (RMR), modified RMR, Q‐system, geological strength index (GSI), rock mass index (RMi), and rock structure rating (RSR) are evaluated and presented here. The parameters mentioned above are the input parameters for squeezing study in Karaj and NWTC tunnels. According to different methods of squeezing evaluation of tunnel presented in tables, the results of two case studies are presented in this paper.

One of the more significant findings to emerge from this study showed that about 3 km of the second part of NWTC tunnel, and 2 km of the Karaj tunnel have high squeezing potential. This research deals with not only an overview of the methods used for the identifying and quantifying of squeezing along with the empirical and semi‐empirical approaches presently available in order to anticipate the potential of squeezing tunnel problem, but also the case studies of NWTC and Karaj tunnels to evaluate and compare the potential of squeezing by different methods. These two tunnel case studies have high potential of squeezing therefore the lining of those two tunnels must be strong enough to overcome this issue.

This study is a precise and concise comparison of the evaluation of tunnels under squeezing rock condition. The present study confirms the previous findings and contributes additional evidence that suggests that there are many studies conducted using empirical and analytical methods to determine the squeezing phenomenon in tunnels. This paper responds to the various questions like, what is the squeezing phenomenon. How can we quantify the potential of squeezing in weak rock? What are the different approaches to the understanding of squeezing phenomenon?

In the fertile line of research on consumer value from the services literature, a gap exists between theoretical and empirical knowledge, in particular regarding Holbrook’s conceptual value framework. The purpose of this paper is to find construct validity for a multidimensional value scale based on Holbrook’s proposal.

Based on a literature review, a qualitative phase, and consultation with an expert, eight value scales (efficiency, service quality, play, aesthetics, status, esteem, ethics, and escapism as an adaptation of spirituality) are tested on a sample of 585 hotel customers and are further analyzed with simple and partial correlations, multiple regressions, and structural modeling.

Following the literature on the merits of Holbrook’s value typology, results are presented in three concatenated phases: validation of Holbrook’s eight value scales corresponding to his eight value types; interrelationships between these value types showing a predominance of the extrinsic-intrinsic and self-other dimensions; and construction of six indices based on the 2×2×2 matrix (self, other, extrinsic, intrinsic, active, and reactive) and a value index as a higher-order representation. The results support Holbrook’s typology, thereby supporting construct validity for the multidimensional scales.

Implications for further conceptual research on value are presented. Meanwhile, the empirical study is context-specific, i.e. related to a hospitality experience.

Although Holbrook’s typology has gained widespread attention, to the best of the authors’ knowledge, no previous research has tested all eight value types simultaneously in the same empirical work.

The purpose of this paper is to review the extant literature on empirical research in supply chain management (SCM). It provides a comprehensive assessment of research methodology of 619 empirical research articles on SCM published between 1994 and 2009. In total, 21 journals were short listed out of 115 journals for the purpose.

The paper reviewed a set of 619 empirical research articles in SCM research with respect to empirical research methodology and its related aspects, using the empirical research approach given by Flynn et al. The paper demonstrates the present status of empirical research in SCM.

It is concluded from the analysis of the results that empirical research in SCM is increasing at a faster rate than ever, with theory building more in focus than verification. On the other hand, SCM researchers seems to have left several aspects of empirical research unexplored, such as action research, significance of triangulation of data and longitudinal data collection. Other significant findings revealed that SCM research is very scanty in developing countries, the majority of research papers are written at firm level only and several industrial sectors such as construction, retail, and agriculture are still unexamined.

There have been a couple of literature reviews in SCM but none of them focused exclusively on empirical research methodology in SCM. Also the sample size with respect to the number of papers (619 papers), as well as number of journals (21 journals), is larger than ever considered for literature review in SCM. The papers spans a longer time period of 16 years (1994‐2009).

A discipline is bound by some combination of a shared subject matter, shared theory, and shared technique. Yet modern economics is seemingly without limit to its domain. As a discipline without a shared subject matter, what is the binding force of economics today? The authors combine topic modeling and text analysis to analyze different approaches to inquiry within the discipline of economics. The authors find that the importance of theory has declined as economics has increasingly become defined by its empirical techniques. The authors question whether this trajectory is stable in the long run as the binding force of the discipline.
