Abstract
We discuss the problem of the classification of continuous‐amplitude stochastic signals by their variety. It is shown in this context that continuous Gaussian processes must be characterized by three parameters which are intimately related to the ability of the process to carry information. Finally, conservation laws for the variety of stochastic signals under feedback are given, and the relation of variance and variety is discussed.

Abstract
Purpose
The main objective of this research is to investigate the factors that influence consumer purchase decisions for halal products before and during the COVID-19 pandemic, based on the Engel-Kollat-Blackwell (EKB) theory.
Design/methodology/approach
The research was conducted as a survey. The influencing factors were determined based on the grey relational analysis (GRA) approach.
Findings
The findings indicate before the COVID-19 pandemic, consumers mainly purchased halal products based on four key factors: purchasing experience, certification label, Internet searches and past consumption experience. However, during the pandemic, the ranking and factors have changed to six indicators, which are past consumption experience, purchasing experience, certification labels, standardized specifications, Internet searches and halal certification labels.
Research limitations/implications
The study was limited by the sample size and geographical area. Nevertheless, the findings could be further explored by expanding related theories toward understand human decisions based on spiritual beliefs.
Practical implications
The findings of this study have important implications for research, practice and society. Understanding the factors influencing halal purchase decisions before and during the pandemic can help businesses, policymakers and halal certification bodies to better cater to consumers' needs and preferences and ensure the continued growth and development of the halal industry.
Originality/value
This study evaluates halal purchasing decisions between periods of certainty and uncertainty by using the GRA. Changes in halal consumption and purchase decisions in response to COVID-19 pandemic have become an emerging topic of discovery. The study addresses the gap in the literature regarding changes in consumer decision pattern.

Abstract
Purpose
Effectuation has received increased attention in the field of entrepreneurship. However, previous studies have focused on performance rather than on networking and word-of-mouth (WOM) marketing. Therefore, the purpose of this study is to understand the mediating effect of networking on the relationship between effectuation and WOM marketing.
Design/methodology/approach
This study used partial least squares structural equation modeling to investigate the relationship between effectuation and WOM marketing mediated through networking. The research model was assessed using data from a sample of 256 entrepreneurs.
Findings
The results reveal that effectuation positively influences WOM marketing, mediated by networking. This study provides new insights into the precursors of WOM marketing and highlights the importance of networking in this process.
Practical implications
The implications of these findings suggest that entrepreneurs should create networking plans that focus on the maintenance and creation of new customers. This plan could be tracked via email, cell phone or online social data to maintain awareness of the failures and successes of the process and for continual improvement.
Originality/value
A vast number of studies have been conducted on effectuation and networking. However, to the best of the authors’ knowledge, no previous study has investigated the influence of these two variables on WOM marketing. Entrepreneurs face long-term sales challenges, and this study proposes that networking could be a solution, thereby increasing WOM marketing sales.

Abstract
Purpose
The acceptance and perception of people regarding 3D bioprinted meat are considered as primary concerns but have not been widely evaluated. This study aimed to determine how biospheric, altruistic, egoistic, ecological worldviews, awareness of consequences, social norms and personal norms affect the consumption intention of 3D bioprinted meat as a future food source.
Design/methodology/approach
The values-beliefs-norms theory grounded this study. An online survey was conducted with 600 valid respondents for analysis utilizing the structural equation modeling method.
Findings
It was found that the ecological worldview had the highest significance, and biospheric and egoistic values positively impacted individuals’ ecological worldview. The awareness of consequences and social norms was also seen to directly influence personal norms, leading to consumption intention. However, it was determined that altruistic values toward an ecological worldview had no significant effect, as an individual's moral values are not affected by other people's well-being.
Practical implications
This study was able to assess and discover the positive consumption intention among Filipinos, highlighting societal norms and pro-environmental behavior. The findings may help manufacturers market 3D bioprinted meat effectively and aid studies on environmentalism, social movements and consumer behavior, leading to acceptance of the development and proliferation of cultured meats.
Originality/value
There have been no studies on cultured meats such as 3D bioprinted meat in the Philippines. The current study was able to fully assess the pro-environmental behavior among Filipinos and intention for 3D bioprinted meat against the generic behavioral assessment among related studies. Comparison was presented based on the findings.

Abstract
Purpose
Consumer adoption of online shopping continues to increase each year. At the same time, online retailers face intense competition and few are profitable. This suggests that businesses and researchers still have much to learn regarding key antecedents of online shopping adoption and success. Based on extensive past research that has focused on the importance of various online shopping antecedents, this work seeks to provide an integrative, comprehensive nomological network.
Design/methodology/approach
The authors employ a mixed-methods approach to develop a comprehensive model of consumers online shopping behavior. To that end, in addition to a literature review, qualitative data are collected to identify a broad array of possible antecedents. Then, using a longitudinal survey, the model of consumer shopping intentions and behaviors is validated among 9,992 consumers.
Findings
The authors identified antecedents to online shopping related to culture, demographics, economics, technology and personal psychology. Our quantitative analysis showed that the main drivers of online shopping were congruence, impulse buying behavior, value consciousness, risk, local shopping, shopping enjoyment, and browsing enjoyment.
Originality/value
The validated model provides a rich explanation of the phenomenon of online shopping that integrates and extends prior work by incorporating new antecedents.

Abstract
Purpose
This study aims to investigate the influence of additive manufactured polymer injection moulds on the mechanical properties of moulded parts. Therefore, polymer moulds are used to inject standard specimens to compare material properties to specimens produced using a conventional aluminium tool.
Design/methodology/approach
PolyJet technology is used to three-dimensional (3D)-print a mould insert in Digital ABS and selective laser sintering (SLS) technology is used to 3D-print a mould insert in polyamide (PA) 3200 GF. A conventionally aluminium milled tool serves as reference. Standard specimens are produced to compare resulting mechanical properties, shrinkage behaviour and morphology.
Findings
The determined material characteristics of the manufactured prototypes from the additive manufactured tools show differences in terms of mechanical behaviour to those from the aluminium reference tool. The most significant differences are an up to 25 per cent lower tensile elongation and an up to 63 per cent lower elongation at break resulting in an embrittlement of the specimens produced. These differences seem to be mainly due to the different morphological structure caused by the lower thermal conductivity and greater surface roughness of the polymer tools.
Research limitations/implications
The determined differences in mechanical behaviour can partly be assigned to differences in surface roughness and morphological structure of the resulting parts. The exact extend of either cause, however, cannot be clearly determined.
Originality/value
This study provides a comparison between the part material properties from conventionally milled aluminium tools and polymer inserts manufactured via additive tooling.

Abstract
Purpose
There is a continuing discussion about whether German valuation methods are inaccurate and inferior to the British standard, and the enduring efforts for a European and internationally standardised valuation method and value definitions intensify this discussion. The German valuation system is said to lead to valuations which do not reflect actual market conditions and excessive smoothing. Not surprisingly, German surveyors usually disagree and claim that the German valuation approach, with its sustainable rental value, fulfils not only its purpose but is more transparent and thus superior to the approach usually applied in UK. The purpose of this paper is to discuss the recently adjusted German valuation methods.
Design/methodology/approach
The paper analyses the German valuation methods and highlights the predominant differences to the British valuation standards.
Findings
The paper shows that the discussed valuation methods should lead to comparable results. The legal framework of the German valuation approaches can therefore not be blamed for any of the observed empirical phenomenon.
Originality/value
The paper discusses the recently adjusted German valuation methods.

Abstract
Purpose
Drawing on the literature on dynamic capabilities and digital transformation, this paper conceptualises and investigates the relevant antecedents of an essential capability for digital transformation – the digital transforming capability – and its effect on the competitive advantage of firms.
Design/methodology/approach
A framework with individual and organisational microfoundations of the digital transforming capability is proposed based on previous research. The digital transforming capability is conceptualised as a second-order construct. The model is tested using data from a broad spectrum of large US companies. Structural equation modelling (SEM) is applied to test the proposed framework.
Findings
The study identifies three main microfoundations that, when combined, build a digital transforming capability (digital-savvy skills, digital intensity and context for action and interaction); in addition, the study tests the relationship between digital transforming capability and firm performance. The results validate the proposed theoretical framework. In addition to proposing relevant microfoundations of the digital transforming capability, we advance knowledge on the performance effects of those microfoundations.
Originality/value
The paper contributes to advancing the understanding of the digital transformation phenomenon by revealing the role of the primary components underlying the digital transforming capability. Yet the mechanisms by which the micro-level aspects are important for digital transformation and organisational outcomes are only suggested by anecdotal evidence. The paper also contributes to ongoing calls for further investigation to extend the understanding of the microfoundations of dynamic capabilities. Finally, by drawing on archival data, this study also contributes to calls to broaden the toolkit used in dynamic capabilities research.

Abstract
Legal intermediation is an emerging theoretical concept developed to grasp the importance of the process and actors who contribute to legal endogenization, in particular in the field of economic activities and work governed by various public regulations. This chapter proposes to extend the analytical category of legal intermediary to all actors who, even if they are not legal professionals, deal on a daily basis with legal categories and provisions. In order to deepen our understanding of these actors and their contribution to how organizations frame legality, this chapter investigates four examples of legal intermediaries who are not legal professionals. Based on field surveys conducted over the past 15 years in France on employment policy, industrial relations, occupational health and safety regulation, and forensic economics, I make three contributions. First, the cases show the diversity of legal intermediaries and their growing and increasingly reflexive roles in our complex economies. Second, while they are not legal professionals per se, to different degrees, these legal intermediaries assume roles similar to those of legal professionals such as legislators, judges, lawyers, inspectors, cops, and even clerks. Finally, depending on their level of legitimacy and power, I show how legal intermediaries take part in the process of legal endogenization and how they more broadly frame ordinary legality.
