This paper aims to investigate the influence of stearate types on the thickening ability, dropping point and fiber structure of greases.
Abstract
Purpose
This paper aims to investigate the influence of stearate types on the thickening ability, dropping point and fiber structure of greases.
Design/methodology/approach
Several greases were prepared from polyolefins and various stearates. The melting point of the stearates and the dropping point of the resultant greases were measured, and the intermolecular binding energies of the thickener and the radial distribution function of the metal–oxygen in the thickener were determined with the aid of molecular simulation. The microstructures of the greases were also analyzed via scanning electron microscopy.
Findings
A higher stearate binding energy was found to correlate to a higher dropping point of the resultant greases. The thickening ability of the stearate is related to the group and period of the constituent metal ion. Within a group, greater atomic numbers of the metal were correlated to lower thickening ability. In a period, as the atomic number of the metal increased, the thickening ability was enhanced. The radial distribution functions of metal and oxygen can explain the aggregation of the stearate thickeners in the grease.
Originality/value
This work compared the thickening capacity of several stearates. Guidelines for preparing stearates to tailor the resultant grease are presented.

Abstract
Purpose
The purpose of this study is to investigate how and why formal mentoring support reduces newcomers' intention to leave from the perspective of uncertainty reduction theory.
Design/methodology/approach
Time-lagged data were collected from two sources, mentors and newcomers, and 193 paired data sets were included in the analysis.
Findings
The results showed that formal mentoring support was positively related to newcomers' person–organisation fit (P–O fit) and person–job fit (P–J fit). In addition, P–O fit and P–J fit mediated the relationship between formal mentoring support and newcomers' intention to leave. Moreover, newcomers' uncertainty avoidance orientation strengthened the relationship between formal mentoring support and perception of fit, and it strengthened the indirect effect between formal mentoring support and newcomer's intention to leave, via the perception of fit.
Originality/value
This study enhances our understanding of the underlying mechanism between formal mentoring support and newcomers' intention to leave. Moreover, it demonstrates that uncertainty avoidance orientation is an important boundary condition during the process of organisational socialisation. The findings also contribute to the organisational socialisation and the mentoring literature by providing evidence from a blue-collar sample.

Abstract
Purpose
Blockchain technology (BT) is creating a new standard for all business operations. It can assist businesses in handling the complexity of circular digital supply chain (DCM) management. Despite this optimistic view, several barriers hinder its implementation. In this regard, this study contributes to Industry 4.0, circular economy (CE), the viability with a critical emphasis on its potential ramifications and influence on the future agenda while using BT technology in the supply chain (SC). In addition, the research reduces the knowledge gap by investigating and ranking the key barriers to the deployment of BT in viable circular digital supply chains (VCDSCs) and studies their interdependencies and causal relationships. The purpose of this paper is to address these issues.
Design/methodology/approach
The barriers to BT adoption in the VCDSC are identified through a thorough literature review and considering viability performance. These barriers are then classified using the analytical hierarchy process (AHP) method. Decision-making trial and evaluation laboratory (DEMATEL) is then employed to examine the cause/effect, correlation, and connection among the 14 barriers selected barriers from the AHP classification to estimate each barrier's overall degree of impact over the others.
Findings
This paper identifies and analyzes the BT adoption barriers in the VCDSC as well as examines how the key barriers interact. As a result, according to the AHP/DEMATEL method, the most prominent influencing barriers to the BT implementation in the VCDSC are “Data transparency,” “Market competition,” “Missing infrastructure,” “Lack of standardization,” “Complex protocol,” “Lack of industry involvement,” “Financial constraints,” “Missing infrastructure,” “Data transparency” and “Interoperability.” The outcomes offer a potential path for identifying important barriers as well as insight into the implementation of BT in the SC while integrating different capabilities such as viability, sustainability and CE principles.
Practical implications
Managers and researchers will benefit from this research by gaining an understanding of the challenges that must be prioritized and examined for BT to be implemented successfully in the VCDSC.
Originality/value
The use and implementation of blockchain-enabled VCDSC continue to face challenges despite an increase in relevant practice and research. Despite the benefits of BT, managers struggle to apply such technology in the context of their company. In this respect, this paper uses an integrated AHP–DEMATEL for categorizing the BT barriers as well as the interrelationship between them. In this respect, this paper presents the BT barriers studied are those related to the use of BT in the SC while integrating different paradigms such as viability, digitalization and CE. While many studies look at the barriers to BT adoption; none of them has ever included the viable capability, which means the ability to “react agilely to positive changes, be resilient to absorb negative events and re-cover after disruptions and survive at long-term periods.” The study concludes with insightful comments based on the findings and suggestions for eradicating those obstacles and their associated effects.

Abstract
The appropriate laundering conditions for the care of polylactide (PLA) textiles have been found. One problem with PLA is its poor resistance to hydrolysis and dramatic loss in strength at conditions typically used in textile processing such as alkaline conditions and elevated temperatures. In this study, PLA fabrics underwent 50 home laundering cycles at various pH levels (8 or 10), washing temperatures (35°C or 55°C), and drying conditions (line dry at 21°C/65% relative humidity or tumble dry at 50 or 70°C). After every 10 laundering cycle, the breaking tenacity, breaking elongation, and modulus of yarns in the PLA fabric were measured. It was found that washing PLA fabrics at pH 8 and 35°C and line drying it at 21°C and 65% relative humidity resulted in greater retention in mechanical properties than washing them at pH 10 and 55°C and tumble drying at 70°C. The authors therefore recommend the following care instructions for PLA textiles: use mild detergents with relatively low pH (pH 8), machine wash cold (35°C), and line dry. If machine drying is desired, tumble dry at the low heat setting or permanent press setting (50°C) is recommended.

Abstract
Purpose
Unlike well-documented market or behavioral uncertainty, patent uncertainty has been significantly under-explored in the field of international entrepreneurship. Drawing on an institution-based view of strategy, this study investigated Netac, a Chinese knowledge-based international new venture (KINV), which was facing uncertainty over patents in China and the US. The aim was to address two questions: (1) how does patent uncertainty emerge in the context of KINVs? And (2) how can KINVs navigate patent hazards by interacting with national patent institutions?
Design/methodology/approach
A longitudinal single-case study approach was adopted as the most appropriate method for exploring novel business phenomena and dynamic processes.
Findings
Results suggested that a KINV can adopt strategies to build a unique identity and so better conform to the expectations of institutions that ultimately decide on patent validity. Strategies may involve building institutional awareness, amplifying mass media effects, and strategically managing the intellectual property and socio-emotional tensions between China and the US.
Originality/value
This study introduced the notion of patent uncertainty into research around international new ventures, highlighting how this type of uncertainty in the advanced technology sector can affect the end-product and patent licensing opportunities of KINVs. It also explored the institution-based view of company strategy in the internationalization process by emphasizing interactive institutional mechanisms, and the role of an organization’s identity when interacting with institutions. The study enriches the literature on institutional theory and organizational identity, and also suggests solutions for firms dealing with efforts by competitors to invalidate patents.

Abstract
Purpose
This study aims to investigate the influence of soy protein isolate hydrolysates (SPIH) obtained using 4 h hydrolysis under 200 MPa on proximate composition, cooking loss, textural properties, color, water distribution, microstructure, thiobarbituric acid reactive substance (TBARS) value and carbonyl and sulfhydryl contents of emulsion sausages.
Design/methodology/approach
Sausages with SPIHs at four concentrations (0, 1.0, 2.0 and 3.0%) were prepared, and the sausage with 0.01% butylated hydroxyanisole (BHA) was used as a positive control. Some sausages were selected for the analyses of quality characteristics and microcosmic properties. Other sausages were stored under 4 °C for 0, 7, 14, 21 and 28 days to investigate the oxidative stability.
Findings
The addition of SPIHs at various levels (0–3.0%) or 0.01% BHA did not affect the proximate composition (protein, fat and ash) of emulsion sausages. The addition of 2.0% SPIH decreased cooking loss and increased moisture content, hardness, springiness, chewiness, resilience and L* value, compared to the sausages without SPIH and with 0.01% BHA (p < 0.05). Furthermore, low-field nuclear magnetic resonance results suggested that sausages with 2.0% SPIH had the shortest T2 relaxation time. In addition, 2.0% SPIH and 0.01% BHA could inhibit the oxidation of emulsion sausages when compared with the sample without SPIH (p < 0.05). Moreover, there were no differences between sausages with 2.0% SPIH and 0.01% BHA (p > 0.05).
Originality/value
These findings confirmed that the 2.0% SPIH obtained under 200 MPa can be used as a natural additive to improve quality properties and antioxidant potential of emulsion sausages during storage.

Abstract
Purpose
The implementation of the digital economy has had a considerable influence on the manufacturing industry, and this paper aims to address the important issues of how to capture the opportunities presented by digital innovation and promote the transformation and upgrading of the manufacturing industry, as well as the improvement of quality and efficiency.
Design/methodology/approach
Using panel data from 30 Chinese provinces and cities between 2010 and 2021, this study establishes the panel vector autoregression (PVAR) model and uses impulse response function analysis to evaluate the influence of the digital economy on the high-quality transformation and upgrading of China's small home appliance industry across five dimensions under the digital economy.
Findings
The development of digital infrastructure has not demonstrated a noteworthy capacity for advancing the transformation and upgrading of the small home appliance industry. Furthermore, digital industrialization has exerted a minimal restraining influence on this process. Nevertheless, digital governance has consistently exhibited a substantial impact on facilitating the transformation and upgrading of the small home appliance industry. While both industrial digitization and digital innovation hold significant potential for promoting the transformation and upgrading of the small home appliance industry, their sustainability remains limited.
Practical implications
The organization should logically join independent innovation and open innovation, construct an industrial ecosystem for the profound convergence of the digital economy and compact household appliances, use digital-wise science and technology to empower the establishment of brand effects, strengthen the portrayal of the digital standard framework for the intelligent compact household appliance industry, advance the development of a public stage for computerized administrations in the compact household appliance industry and develop a strategy ecosystem for computerized assets in the compact household appliance industry.
Originality/value
This study offers systematic evidence of the relationship between the digital economy and the development of the small home appliance industry. The results of this research contribute to the literature on the impact of the digital economy on the manufacturing sector and provide a logical explanation for the transformation and upgrading of the small home appliance industry within the context of the digital economy.

Abstract
Purpose
This paper aims to investigate the role of informational and relational mechanisms on equity crowdfunding investors' conformity behaviors by focusing on a relational culture of China.
Design/methodology/approach
The data of 108 financing projects and 7,688 investment records from a union of Chinese equity crowdfunding platforms are gathered. Lead investors' response to a campaign and follow-investors’ former links explain investors' conformity by social network analysis (SNA) and ordinary least squares (OLS) analysis.
Findings
The results show that informational and relational influences drive conformity in Chinese equity crowdfunding. Moreover, the informational influence weakens in a highly centralized structure of linked investors.
Research limitations/implications
The results add new knowledge to follow-investors’ conformity behaviors in equity crowdfunding and enrich the literature on conformity theory by finding the contextual effect of information-influenced conformity and the adaption of conformity theory to cultural uniqueness. Besides, this preliminary work also suggests opportunities for future research.
Practical implications
The paper inspires new consideration on a strategical use of follow-investors’ conformity mentality to promote successfully financing and reminds platform managers to be alert to the interference of small groups formed based on informal relationships to the normal financing order.
Originality/value
This is the first study that discovers the non-informational influence and the limited influence of information on equity crowdfunding conformity through contextual concerns.
