Abstract
Purpose
The purpose of this article is to design and make fabrics with colorful melange yarns spun by a three-channel rotor spinning machine.
Design/methodology/approach
The three-channel digital rotor-spun machine controls the blending proportion by adjusting the feeding of three-primary color fiber slivers online, so that a piece of colorful yarn presents a variety of colors along the longitudinal direction where constant yarn linear density can be produced flexibly. Various fabric patterns can be produced by three-channel rotor-spun colorful melange yarn with different periods of color.
Findings
The fabric, made by the rotor-spun colorful melange yarn, is rich in color, clear in layers, soft in the hand and has a hazy three-dimensional effect. The product is environmentally friendly and saves energy.
Originality/value
An innovative idea to develop various colorful fabrics is proposed by combining their pattern with colorful melange yarn produced by a three-channel rotor spinning machine.

Abstract
Purpose
The vast majority of research on traditional leadership focuses on effective and positive leadership behavior. However, scholars have begun to pay attention to the impact of negative leadership behavior on employees and the organization. Hence, the main purpose is to examine the effects of abusive supervision. While the literature does not examine the time future orientation of the effects of abusive supervision, the purpose of this paper is to fill up this gap and examine the moderating role of future orientation.
Design/methodology/approach
A total of 584 valid questionnaires were collected from respondents aged between 21 and 30 years old and analyzed using the hierarchical regression and structural equation modeling method.
Findings
The main results show that abusive supervision positively affects counterproductive work behavior and future orientation positively moderates both the relationship between abusive supervision and originality behavior and the relationship between abusive supervision and organizational citizenship behavior (OCB).
Originality/value
This study demonstrates the moderating roles of future orientation in the effects of abusive supervision, and thus deepens the understanding of the moderating effect. It departs from the prior works and presents a more detailed examination examines the distinct dimensions of personality traits. It makes three main theoretical contributions. First, it introduces uncertainty management theory as a means to interpret the effects of abusive supervision. Second, it contributes to the literature on abusive supervision. Third, it does not lead to discovery as an OCB and originality, conclusions which differ from the results suggested in past literature.

Abstract
Purpose
This paper aims to document the adaptation strategies developed by local farmers to adjust to climate change and related hazards in Lijiang Prefecture in Southwest China, and quantify the determinants of the adaptation measures.
Design/methodology/approach
The study conducted a household survey with 433 respondents in Lijiang to documents adaptation measures. The authors used a multivariate probit model to quantify five categories of adaptation measures against a set of household features, extension and information, resources, social network, financial assets and perception variables.
Findings
The most significant determinants consisted of information on early climate warnings and impending hazards, ownership to land and livestock, irrigation membership in community-based organisations, household savings, cash crop farming and perceptions of climate change and its related hazards. Adaptation strategies and policies highlighting these determinants could help to improve climate change adaptation in the region.
Originality/value
This study quantified the determinants of adaptive strategies and mapped important determinants for the region that will provide farmers with the appropriate resources and information to implement the best practices for adapting to climatic changes. The method and findings could be useful and easily replicable for future agriculture policies.

Abstract
Purpose
This study aims to apply the affective events theory and psychological contract theory to investigate how job satisfaction and psychological safety mediate the effect of the behavioral integrity of supervisors on the organizational commitment of employees.
Design/methodology/approach
A questionnaire survey was conducted using purposive sampling. In total, 500 questionnaire copies were distributed, and 453 responses were collected, of which 441 were valid (valid response rate = 88.2%).
Findings
The behavioral integrity of supervisors has a direct negative effect on organizational commitment but significant positive effects on job satisfaction and psychological safety, and job satisfaction and psychological safety have significant positive effects on organizational commitment. Job satisfaction and psychological safety have significant mediating effects on the association between the behavioral integrity of supervisors and the organizational commitment of employees.
Practical implications
Leaders and top management should “practice what they preach,” integrate honesty into organizational culture through training and establish a code of conduct to ensure that employees uphold their commitments. Companies should establish appropriate disciplinary systems and norms related to work and other aspects of organizational culture; they should also establish fair, just and open assessment systems to minimize the gap between their employees’ actual and expected earnings.
Originality/value
This study is the first to simultaneously consider the mediating effects of job satisfaction and psychological safety on the association between behavioral integrity and organizational commitment.

Abstract
Purpose
This paper aims to present the mixed elastohydrodynamic lubrication (EHL) model and obtain the leakage characteristics for the skeleton reciprocating oil seal.
Design/methodology/approach
The model consists of a finite element analysis of the contact pressure, a fluid mechanics analysis of the fluid film, a contact analysis of the asperity contact pressure, a deformation analysis of the seal lip and an iterative numerical simulation process.
Findings
Simulation results show that the leakage is in direct proportion to the seal roughness and speed, and in inverse proportion to the fluid viscosity. Comparisons with the experimental results verify the validity of the mixed EHL model.
Originality/value
This study provides a helpful method to calculate the leakage of the skeleton reciprocating oil seal, which shortens its development cycles.

Abstract
Purpose
With social media usage growing rapidly in business sustainability in manufacturing sectors, the means through which manufacturing firms can incorporate it into the pursuit of environmental sustainability are largely under-researched by academics. Drawing upon the dynamic capability view, this study examines the indirect relationship between social media usage and sustainable innovation in manufacturing sectors.
Design/methodology/approach
The study was based on analyzing data collected through a questionnaire survey on Chinese manufacturing firms. Partial least squares structural equation modeling was applied to test the hypotheses.
Findings
The results show that social media usage has a positive effect on sustainable innovation in the manufacturing sectors. Firms' sustainable dynamic capability mediates the relationship between social media usage and sustainable innovation. In addition, the effects of social media usage on firms' sustainable dynamic capability are stronger when stakeholder pressure is stronger and top management team commitment is higher.
Originality/value
This study highlights social media application as an important, yet underexplored, factor in sustainable innovation of manufacturing firms. The findings also untangle the mechanism of sustainable dynamic capability by which social media usage improves sustainable innovation for manufacturing firms.

Abstract
Purpose
With continuous concerning on the toxic of element Pb, Pb-free solder was gradually used to replace traditional Sn-Pb solder. However, during the transition period from Sn-Pb to Pb-free solder, mixing of Sn-Pb and Pb-free is inevitable occurred in certain products, and in China where Sn-Pb solder was still used extensively in certain areas especially. Correspondingly, understanding reliability of Sn-Pb solder joints was very important, and further studies were needed.
Design/methodology/approach
Thermal shock test between −55°C and 125 °C was conducted on Sn-37Pb solder bumps in the BGA package to investigate the microstructure evolution and the growth mechanism of interfacial intermetallic compound (IMC) layer. The effects of thermal shock on the mechanical property and fracture behavior of Sn-37Pb solder bumps were discussed.
Findings
Pb-rich phase was coarsened and voids were increased at first; Pb-rich phase was refined and voids were decreased secondly with the increase of thermal shock cycles; the shear strength of solder bumps was slightly decreased after thermal shock, but was back up to 73.67MPa at 2,000 cycles; interfacial IMCs of solder bumps was from typical scallop-type into smooth, the composition of IMCs was from Cu6Sn5 into Cu6Sn5 and Cu3Sn after thermal shock with 1,500 and 2,000 cycles; 20.0 per cent of solder bumps at 1,500 cycles and 9.5 per cent of solder bumps at 2,000 cycles were failure respectively.
Originality/value
Compared with the board level test method, the impact shear test for the single solder bump is more convenient and economical and is actively pursued by the industries. The shear strength of solder bumps was slightly decreased after thermal shock, but was back up to 73.67 MPa at 2,000 cycles; 20.0 per cent of solder bumps at 1,500 cycles and 9.5 per cent of solder bumps at 2,000 cycles were failure.

Abstract
This study explores the short- and medium-term effects generated by the Milan Expo 2015, adopting a microeconomic approach. The focus is on the hospitality sector. The study embraces nine years, identifying three intervals: pre- (2011–2014), during- (2015) and post-Expo (2016–2019). The time span does not include the Covid-19 pandemic period, which started in 2020. The dataset is composed of daily data. Three research questions are explored. First, an overall evaluation of the short- and medium-term effects is performed. Second, the seasonal effects are measured. Finally, the impacts for different classes of hotels are considered. The findings are supportive for the legacy generated by the Milan Expo. The results confirm the ability of the Milan Expo to strengthen the leisure segment. Positive results have been observed for all classes of hotels, relevantly augmenting the real revenue per available room (RevPAR). Luxury hotels achieved the highest increase of RevPAR, while economy class hotels registered the highest percentage of increase of RevPAR.

This study aims to examine how operator type moderates the relationship between hotel information technology (IT) expenditures and operating performance.
Abstract
Purpose
This study aims to examine how operator type moderates the relationship between hotel information technology (IT) expenditures and operating performance.
Design/methodology/approach
By adapting and extending O’Neill et al.’s (2008) and Hua et al.’s (2015) research, this study constructed an empirical model and tested proposed hypotheses, with Newey and West (1994) errors computed to accommodate potential heteroscedasticity and autocorrelation issues.
Findings
Operator type moderates the impact of hotel IT expenditures on operating performance. In particular, it appears that the operator type of franchising exerts a stronger moderating effect compared with other operator types explored.
Practical implications
This study, as the first of its kind, shows that the choice of operator type shapes how a hotel can effectively use IT expenditures to improve operating performance. This finding can be beneficial for hotel owners when making operator type decisions. In addition, operator type moderates the direct impact of IT expenditures on revenues and gross operating income. This study’s results show that franchised hotels seem to use IT expenditures more effectively compared with independently owned hotels.
Originality/value
This study contributes both theoretically and practically to understand how operator type moderates the relationship between IT expenditures and hotel performance. The research outcome provides a more holistic view that governs the relationships between IT expenditures, operator type and operating performance.
