Abstract
A computer program, CALFEM, is presented. This interactive computer program is designed as a tool for teaching of the finite element method. No programming knowledge is needed. The program is well suited to solve problems in structural mechanics and for solution of field problems. A variety of finite elements is available. One objective when designing CALFEM was that the user shall understand every part of the computational procedure. The program is based on a command language. All information is stored in user‐defined matrices created by usage of commands. Required input to matrices are given on request from the program. The contents of the matrices can be looked upon at any time and new decisions can be made in the course of the run. The user of the program determines in which way he wants to proceed with the calculation process by choosing proper commands. This means that everything in the computational procedure is under the direct control of the user. This is in contrast to many conventional ‘black box’ finite element programs. Commands can be stored on user‐defined secondary storage files. The files can be edited in CALFEM and be used further on in the calculation procedure. The program is written in FORTRAN 77 and all calculations are performed in double precision.

Abstract
Purpose
The purpose of this article is to examine whether, and if so, to what extent, noncoercive isomorphism determines mandatory disclosure compliance at a later stage of an accounting reform.
Design/methodology/approach
The analysis of compliance is based on data from 289 Swedish municipalities for 2016, which is nearly two decades after the initial legal reform in which mandatory requirements were imposed by the Swedish government in an effort to harmonize financial reporting practice. Following the standard approach in the literature, an unweighted compliance index was used as dependent variable. Proxies for municipal accounting networks and involvement in professional government accounting associations were used to explain individual municipalities' levels of compliance.
Findings
Differences in individual municipalities' levels of compliance were strongly related to the financial reporting practice of other municipalities in their accounting network. These results suggest that normative and mimetic isomorphic pressure stemming from these local networks, where accounting departments continually meet and share experiences, is a very potent force. In contrast, isomorphic pressure stemming from involvement in activities offered by professional government accounting associations is generally not a potent force at this stage.
Practical implications
In settings where municipal accounting networks exist, it may be effective to stimulate de facto harmonization by directing information, education and other efforts toward the professional environment in which these networks operate.
Originality/value
Unlike prior literature, the data in this study are from a later stage of a public sector accounting reform.

Abstract
Purpose
Using Arroyo’s (2012) institutional entrepreneurship (IE) framework, the purpose of this paper is to enhance our understanding of how top managers interpret change in the macro-political and economic environment and integrate it into their performance management systems (PMSs).
Design/methodology/approach
The paper combines multiple data sources to study PMS change in the big four Swedish banks over the deregulations’ first quarter of a century.
Findings
The findings support previous research by identifying IE as a collective phenomenon. Moreover, it points to the importance of distinguishing between different types of field-level events, when investigating change initiated by such events. Finally, the findings also indicate that change at different levels of analysis have separate timings, advising future research on change to pay closer attention to the aspect of time.
Social implications
The paper tests Arroyo’s (2012) multi-level framework in an accounting setting and specifically focuses on top managers’ interpretation and integration of field-level events. It does so in the specific context of banks and thereby contributes to our understanding of how different field-level events affect banks’ PMS. In the post-financial crisis era, organizational and accounting scholars should engage time and effort to better understand this complex industry, not least to advice policymakers and regulators in the ongoing re-regulation of the financial markets.
Originality/value
Inspired by organizational studies of IE, this paper uses a longer time-frame and includes more organizations, than conventional management accounting case studies. By studying a field, rather than a single organization, the paper opens up to a “wider perspective” on PMS change.

Abstract
Purpose
This paper aims to explore the role of workplace democracy in generating psychological capital, which is an inevitable paradigm for the contemporary organizations. The study also provides a conceptual framework which connotes the nexus between the two constructs.
Design/methodology/approach
The study is qualitative in nature and uses content analysis to identify the determinants of workplace democracy and psychological capital. Furthermore, the study used SPSS macro, i.e. PROCESS, a computational tool for calculating inter-coder reliability by using KALPHA, i.e. Krippendorff’s alpha reliability estimate (Hayes, 2013; Krippendorff, 2011).
Findings
The present study adds to the literature by signaling the dire need for building democratic workplaces and offers significant insights for the management and human resource practitioners to cultivate workplace democracy to build their employees’ psychological strengths, which in turn will result in enhanced organizational outcomes.
Originality/value
The present study brings attention toward the necessity for a shift in the generic organizational strategies and instigate organizations to nurture a democratic setup for developing employees’ psychological capital.

The purpose of this paper is to investigate the influence of different dietary fibers on color, nutritional, physico-chemical, sensory and textural properties of fresh sausage.
Abstract
Purpose
The purpose of this paper is to investigate the influence of different dietary fibers on color, nutritional, physico-chemical, sensory and textural properties of fresh sausage.
Design/methodology/approach
This study was undertaken to determine the effects of partial beef meat substitution (15, 10.5 and 6 percent) at different combinations: barley beta-glucan concentrate (BBC at 1 percent) alone, carrot fiber (ID809 at 1 percent) alone and a mixture of both fibers (BBC and ID809 at 0.5 percent of each), on the quality of fresh sausage.
Findings
Results revealed that the supplementation of dietary fibers generally decreased protein contents and increased moisture. Color parameters were significantly affected by the addition of dietary fibers. Meat substitution with dietary fibers tended toward red coloration, which enhanced sensory properties of fresh sausages, especially general acceptability. Fresh sausages formulated with a mixture of dietary fibers recorded good firmness. Indeed, it increased extrusion force values and provided a greater hardness at sensory level. This manuscript reports that beef sausage formulated with a mixture of BBC and ID809 and reduced beef meat rate improved acceptability to consumer.
Originality/value
The paper approaches a new subject that may be relevant to functional food. There are few research works to evaluate consumer preferences of new product developments and to achieve healthier and more economic fresh sausages formulated with a mixture of two fibers after reducing beef meat content.

Abstract
This chapter explores the concept of market infrastructure, which is tentatively defined as a materially heterogeneous arrangement that silently supports and structures the consummation of market exchanges. Specifically, the authors investigate the enactment of market infrastructure in the US grocery retail sector by exploring how barcodes and related devices contributed to modify its market infrastructure during the period 1967–2010. Combining this empirical case with insights from previous research, the authors propose that market infrastructures are relational, available for use, modular, actively maintained, interdependent, commercial, emergent and political. The authors argue that this conception of market infrastructure provides a powerful tool for unveiling the complex agencements and engineering efforts that underpin seemingly superficial, individual and isolated market exchanges.

Abstract
Purpose
To present results from a research project on postgraduate and undergraduate students' learning about environmental issues in education.
Design/methodology/approach
Three cases were carried out with civil engineering students, biology students and postgraduate students. Discussions in classroom were tape‐recorded, as well as discussions while working with assignments, and interviews were carried out.
Findings
Shows how differently environmental issues can be interpreted, i.e. scientifically, existentially and politically, and the way values and emotions become an aspect of the learning process and reveal the students' difficulties in differentiating between values and descriptions of phenomena. This is analysed and explained in relation to the students' various projects that come into conflict in the educational setting.
Practical implications
The paper can be of use to those who are engaged in environmental education and raises questions regarding the content of today's environmental education.
Originality/value
Gives an insight into students' learning processes and experiences in environmental education and the difficulties they can experience when studying such a subject.

Abstract
Application of the engineering design optimization methods and tools to the design of automotive body‐in‐white (BIW) structural components made of polymer metal hybrid (PMH) materials is considered. Specifically, the use of topology optimization in identifying the optimal initial designs and the use of size and shape optimization techniques in defining the final designs is discussed. The optimization analyses employed were required to account for the fact that the BIW structural PMH component in question may be subjected to different in‐service loads be designed for stiffness, strength or buckling resistance and that it must be manufacturable using conventional injection over‐molding. The paper demonstrates the use of various engineering tools, i.e. a CAD program to create the solid model of the PMH component, a meshing program to ensure mesh matching across the polymer/metal interfaces, a linear‐static analysis based topology optimization tool to generate an initial design, a nonlinear statics‐based size and shape optimization program to obtained the final design and a mold‐filling simulation tool to validate manufacturability of the PMH component.

Abstract
Contact problems are among the most difficult ones in mechanics. Due to its practical importance, the problem has been receiving extensive research work over the years. The finite element method has been widely used to solve contact problems with various grades of complexity. Great progress has been made on both theoretical studies and engineering applications. This paper reviews some of the main developments in contact theories and finite element solution techniques for static contact problems. Classical and variational formulations of the problem are first given and then finite element solution techniques are reviewed. Available constraint methods, friction laws and contact searching algorithms are also briefly described. At the end of the paper, a bibliography is included, listing about seven hundred papers which are related to static contact problems and have been published in various journals and conference proceedings from 1976.

Abstract
Purpose
Productivity is a multidimensional and context-dependent concept. Therefore, many different definitions and consequently, many different approaches to productivity measurement (PM) exist in the literature. As a result, the understanding of productivity and the appropriate use of PM approaches are at a low level. The literature provides some overviews, but these overviews consider only a few selected individual aspects. Therefore, the overviews do not allow a comprehensive comparison and evaluation of existing approaches. This paper aims to give an overview of existing approaches to PM and to classify them according to elaborated criteria based on the main characteristics of productivity.
Design/methodology/approach
Literature review for existing approaches to PM using the following keywords: productivity, PM, productivity measure, labour productivity and labor productivity.
Findings
A total of 38 approaches are identified and listed between 1955 and 2020. The main result is a systematic overview and classification of existing approaches to PM.
Research limitations/implications
Researchers can use the overview to determine the development over time, the current state of research in the field of PM and identify research gaps. The classification can also be used to classify new approaches.
Practical implications
Companies can use the classification as a guide to identifying appropriate approaches to measuring productivity in corporate practice.
Originality/value
This paper enables a comprehensive comparison and evaluation of existing approaches to PM. Also, the understanding of the multidimensional character of the productivity concept is enhanced.
