Abstract
Purpose
This paper aims to study the changes in anti‐nutritional factors during the germination of the Indian bean and also to carryout an evaluation by subjecting it to different cooking treatments – boiling, roasting and pressure cooking.
Design/methodology/approach
The healthy Indian bean (Dolichos lablab L.) seeds were soaked for 12 h and allowed to germinate (sprout) at room temperature 27±2○C for a period of 32 h. Seedlings were withdrawn at designated time intervals and used for analysis of anti‐nutritional factors like trypsin inhibitory activity (TIA), phytic acid, polyphenols and tannins of dried and germinated cotyledons. They were also evaluated regarding their changes by subjecting to different cooking treatments – boiling, roasting and pressure cooking.
Findings
The raw dry Indian bean had a very high TIA which decreases progressively to 17 per cent at 32 h germination period. An overall fall in polyphenols of 70 per cent, tannins 46 per cent, phytic acids 36 per cent and phytate phosphorus to 30 per cent was noticed during the 32 h germination period. Maximum reduction was observed in TIA and phytic acids with roasting, while the boiling and pressure cooking decreases the levels of polyphenols and tannins.
Originality/value
The paper proves that germination is a more effective method in reducing TIA, tannins, polyphenols and phytic acid than the various cooking treatments.

Abstract
Purpose
Legume seeds provide one of the most concentrated sources of nutrients rich in fibre and high‐quality protein in the diet. The present work aims to investigate the hypocholesterolemic effect of germinated Indian bean (Dolichos lablab L. var lignosus) by feeding albino rats with a hypercholesterolemic diet.
Design/methodology/approach
Male albino rats of Wistar strain were divided into five groups (each group consisting of ten rats) according to randomized block design, housed in individual cages and fed with one of the five diets over an eight‐week period. At the end of eight weeks, the body weights were recorded and the rats put down. Samples of blood and liver were collected and used for analysis of liver and plasma cholesterol.
Findings
Supplementation of the diet with dried powder of soaked bean almost brought the plasma cholesterol to 72.5 ± 0.75 from 178 ± 1.85 compared with that of the control (61.5 ± 0.70), although the liver cholesterol was still three times higher compared with the control. The 24h germinated Indian bean cotyledons could effectively counteract the effects of added cholesterol on liver and plasma by their high fibre content coupled with enormous increase in ascorbic acid levels.
Originality/value
Results suggest germination to be a simple biochemical tool to effectively lower the cholesterol levels in liver and plasma by virtue of its higher contents of ascorbic acid and dietary fibre in ischemic heart disease patients.

Abstract
Purpose
The purpose of this paper is to examine the performance of salespeople when selling new products (namely, electronic goods) in a business-to-business context by incorporating the organizations’ perceived psychological climate into goal orientation theory.
Design/methodology/approach
The current study uses the goal orientation theory to examine the performance of 158 salespeople based on new electronic product sales. Organizational psychological climate perceptions (i.e. customer orientation, sales supportiveness and sales innovativeness) are included as variables that can moderate salespeople’s performance. This study used partial least squares to examine its proposed model.
Findings
This study found that the learning goal orientation and the performance-prove goal orientation positively affect salespeople’s self-efficacy to sell new products, whereas a performance-avoid goal orientation negatively affects efficacy. In addition, new product selling self-efficacy itself has a positive influence on new product sales performance. As for the moderator, sales supportiveness and customer orientation have the ability to moderate the relationship between self-efficacy and performance.
Practical implications
This study has implications for sales managers or product managers who are responsible for promoting new products. First, this study’s findings suggest that managers should consider employing performance-prove goal-oriented staff and learning goal oriented staff to sell new products. Second, management can attempt to develop a more supportive climate for the sales team, such as assisting the team in obtaining needed resources from other departments. Finally, management needs to let salespeople know that they are doing their best to understand what new products existing and potential customers will need in the near future.
Originality/value
This current research is one of the first to examine how the perceived psychological climates of organizations (i.e. sales supportiveness, sales innovativeness and customer orientation) may moderate salespeople’s performance when selling new products. Second, this research examines how different types of goal orientation affect salespeople’s self-efficacy when selling new products. Previous results have not always been consistent regarding the influence of a performance-prove goal orientation. Last but not least, this study tests how new product selling self-efficacy mediates the relationships between goal orientations and new product sales performance as scholars have suggested that more research into the mediating role of self-efficacy is needed.

Abstract
Purpose
This work focuses on the interoperability of the blockchain from the viewpoint of its technological evolution in the wider context of supply chain systems. Interoperability concerns the most since it is among the most persevering problems in the process of blockchain adaptation. The study aims to trace and pinpoint all the different methods that affect the interoperability of blockchains, gather all the obtainable evidence and recognize gaps in between the applicable approaches mentioned across the contemporary academic literature.
Design/methodology/approach
An analysis is done of seven interoperability approaches based on their relevance, practical usefulness and adoption processes concerning the blockchain. Mainly, this work examines interoperability from several different perspectives. An interoperability modular decomposition via a layered model has been defined through the level of conceptual interoperability (LCIM) and level of information system interoperability (LISI), which represent the most popular metrics with regard to assessing the level of interoperability from a qualitative level.
Findings
Generally, the findings of this work are directed in two major aspects: Firstly, it expands the research around blockchain technology interoperability by providing crucial background information and pinpointing important connotations for both industrial and academic environments. It also defines and analyzes several different approaches toward the blockchain platform's interoperability. Secondly, it also identifies and proposes several scenarios that take advantage of multiple blockchain application approaches, highlights various issues and challenges to the evolution of interoperability standards and solutions and indicates the desired areas of further research.
Originality/value
An essential aspect of the originality of this paper is that, contrary to other work contributions, this work summarized the different interoperability approaches for blockchain in supply chain systems. Mainly, seven approaches were discussed for practitioners and researchers, and the open issues and future research direction were considered.

Abstract
Purpose
In the past decade, three-dimensional (3D) printing has gained attention in areas such as medicine, engineering, manufacturing art and most recently in education. In biomedical, the development of a wide range of biomaterials has catalysed the considerable role of 3D printing (3DP), where it functions as synthetic frameworks in the form of scaffolds, constructs or matrices. The purpose of this paper is to present the state-of-the-art literature coverage of 3DP applications in tissue engineering (such as customized scaffoldings and organs, and regenerative medicine).
Design/methodology/approach
This review focusses on various 3DP techniques and biomaterials for tissue engineering (TE) applications. The literature reviewed in the manuscript has been collected from various journal search engines including Google Scholar, Research Gate, Academia, PubMed, Scopus, EMBASE, Cochrane Library and Web of Science. The keywords that have been selected for the searches were 3 D printing, tissue engineering, scaffoldings, organs, regenerative medicine, biomaterials, standards, applications and future directions. Further, the sub-classifications of the keyword, wherever possible, have been used as sectioned/sub-sectioned in the manuscript.
Findings
3DP techniques have many applications in biomedical and TE (B-TE), as covered in the literature. Customized structures for B-TE applications are easy and cost-effective to manufacture through 3DP, whereas on many occasions, conventional technologies generally become incompatible. For this, this new class of manufacturing must be explored to further capabilities for many potential applications.
Originality/value
This review paper presents a comprehensive study of the various types of 3DP technologies in the light of their possible B-TE application as well as provides a future roadmap.

Abstract
Business models can be considered as cognitive models that managers or analysts can use to describe, understand, or test business activities. However, the emergence of a new business model requires not only cognitive operations but also concrete modifications to the realities of a company’s operations and structures. In this paper, we adopt a sociomaterial view of organizational change based on actor-network theory, and underline the role of artifacts in the emergence of new business models. We base our discussion on a case study of a French leader in kitchen electric appliances. Despite the fact that the building of its new business model is still in progress, this empirical study provides important suggestions concerning the role of artifacts.

Abstract
Purpose
Multiple-input multiple-output (MIMO) combined with multi-user massive MIMO has been a well-known approach for high spectral efficiency in wideband systems, and it was targeted to detect the MIMO signals. The increasing data rates with multiple antennas and multiple users that share the communication channel simultaneously lead to higher capacity requirements and increased complexity. Thus, different detection algorithms were developed for the Massive MIMO.
Design/methodology/approach
This paper focuses on the various literature analyzes on various detection algorithms and techniques for MIMO detectors. Here, it reviews several research papers and exhibits the significance of each detection method.
Findings
This paper provides the details of the performance analysis of the MIMO detectors and reveals the best value in the case of each performance measure. Finally, it widens the research issues that can be useful for future researchers to be accomplished in MIMO massive detectors
Originality/value
This paper has presented a detailed review of the detection of massive MIMO on different algorithms and techniques. The survey mainly focuses on different types of channels used in MIMO detections, the number of antennas used in transmitting signals from the source to destination, and vice-versa. The performance measures and the best performance of each of the detectors are described.

Abstract
Purpose
This paper aims to investigate the relationship between age and adaptation to changes in the workplace (perceived demand‐ability fit, task performance before and after change). It also seeks to explore two mediators of the potential age‐adaptation relationships: adaptive self‐efficacy and job experience.
Design/methodology/approach
A sample of 117 employees from three multinational organizations completed two questionnaires one month before and three months after changes in their workplaces.
Findings
Hierarchical linear modelling revealed that age was not related to fit and performance before but was negatively related to fit and performance after organizational change. These relationships were mediated by job experience. Job experience made it more difficult for employees – whether young or old – to adapt to workplace changes. Adaptive self‐efficacy did not mediate the negative age‐adaptation association.
Research limitations/implications
In the sample, only a few employees were older than 56 years which might limit the generalizability of the results. Future research should also attempt to include objective performance data.
Practical implications
Managerial interventions regarding learning, development, and job rotation might counteract negative effects of job tenure.
Originality/value
There is little empirical research addressing issues related to age and adaptation in the workplace. The longitudinal field study presented in the paper contributes to the literature on individual adaptation to changes in the workplace by empirically examining the relationship between age and indicators of adaptation, and its mediating factors.
