Abstract
Purpose
Weather affects consumer decision-making. However, academic research on how weather factors affect specific takeaway foods is limited. This paper aims to fill in the gap and therefore to contribute to online marketing and operation.
Design/methodology/approach
Web crawler techniques were first exploited to collect takeaway food ordering data from Meituan, the world’s largest GMV platform. Then statistics models and a time series regression model were selected to study the weather impact on online orders.
Findings
The findings highlight that certain weather factors, such as temperature, air quality and rainfall have clear effects on most category takeaway orders.
Originality/value
Quantitative analysis of weather impacts on the takeaway ordering business will help to guide the online service platforms for marketing promotion and the settled businesses to make reasonable arrangements for inventory and marketing tactics.

Abstract
Purpose
The purpose is to forward systems theory one more step towards social theory and integrate problem-solving and theory-building, and search for the integration and unity of science by revealing the nature and role of critical systems thinking (CST).
Design/methodology/approach
This article describes relations between systems theory and social theory in three parts. First, it examines the links of systems methodologies with three social science approaches as well as the role of CST. Second, the focus of theory and the form of explanation are discussed from critical social science (CSS) perspective. Third, the direction of theorizing of a CST-based systems theory is investigated.
Findings
First, CST is a hidden assumption of system dynamics (SD)/systems thinking (ST). Second, systems theory is positioned in CSS. Third, CST integrates traditional and soft systems methodologies (SSM), and connects systems science and social science. Fourth, this article reveals hidden links between systems approaches and three corresponding social science approaches. Fifth, the theoretical focus of a CST-based systems theory could be formal/structure theory and/or substantive/content theory. Sixth, the form of explanation could be structural/mechanismic explanation combining causal and interpretive explanations. Seventh, a CST-based systems theory may adopt abduction, which complements a defect in deduction and induction in a difficulty of nonlinearity.
Originality/value
It illustrates a graph of the competing approaches in systems science corresponding to paradigms in social science.

Abstract
Purpose
The current research provides a conceptual framework that explains how sales managers' aggression across business-to-business (B2B) sales organizations triggers salespeople's surface acting, deep acting and service recovery performance. It also investigates the moderating role of ethical leadership through sales managers' aggressiveness on service recovery performance.
Design/methodology/approach
The authors test the model using multilevel analysis with cross-sectional data of 367 salespeople from different sales organizations.
Findings
The study shows that the aggression of sales managers has an adverse influence on service recovery performance. Additionally, aggressiveness among sales managers is positively connected with surface acting while adversely affecting deep acting. The study’s findings also indicate that ethical sales leadership is positively moderate among sales managers' aggressiveness and service recovery performance.
Research limitations/implications
The authors collected data from individual salespersons, which is the limitation; however, future studies could collect data using the dyadic approach, such as matching responses from both managers and salespersons. This method could enhance the model's internal validity.
Originality/value
Several studies have mainly focused on positive supervision styles in the literature on service recovery. At the same time, building a negative supervision model in the B2B service recovery context, which has been persistently ignored, is noteworthy.

Abstract
Purpose
Supply chain management (SCM)-embedded valuable resources, such as capital, raw-materials, products, partners, customers and finished inventories, where the evaluation of environmental texture and flexibilities are needed to perceive sustainability. The present study aims to identify and evaluate the directory of green and agile (G-A) attributes based on decision support framework (DSF) for identifying dominating measures in SCM.
Design/methodology/approach
DSF is developed by exploiting generalized interval valued trapezoidal fuzzy numbers (GIVTFNs). Two technical approaches, i.e. degree of similarity approach (DSA) and distance approach (DA) under the extent boundaries of GIVTFNs, are implicated for data analytics and for recognizing constructive G-A measures based on comparative study for robust decision. A fuzzy-based performance indicator, i.e. fuzzy performance important index (FPII), is presented to enumerate the weak and strong G-A characteristics to manage knowledge risks in allied business environment.
Findings
The modeling is illustrated from the insights of decision-makers for augmenting business value based on cognitive identification of measures, where the best performance score is identified by the “sustainable packaging” under the traits of green supply chain management (GSCM). “The use of Web-based applications” under the traits of agile supply chain management (ASCM) and “Outsourcing flexibility” under traits of ASCM is found as the second and third most significant performance characteristics for business sustainability. Additionally, the “Reutilization (recycling) and reprocessing” under GSCM in manufacturing and “Responsiveness and speed toward customers needs” under ASCM are found difficult in attainment.
Research limitations/implications
The G-A evaluation will assist in attaining performance excellence in day-to-day operations and overall functioning. The outcomes will help executives to plan strategic objectives and attaining success.
Originality/value
To reinforce the capabilities of SCM, wide extent of G-A dimensions are presented, concept of FPII is reported to manage knowledge risks based on identification of strong attributes and two technical approaches, i.e. DSA and DA under GIVTFNs are presented for attaining robust decision and directing managerial decision-making process.

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
Purpose
The purpose of this study is to examine whether the required disclosure and the high frequency of key audit matters (KAMs) are likely to moderate the effect of higher credit risk on earnings quality.
Design/methodology/approach
This study uses 15,106 Taiwanese firm-year observations to explore the relationship between earnings quality and credit risk during the 2011 to 2020 period. We use the two-stage least squares method to test whether the presence of KAM disclosures moderated the association between earnings quality and credit risk and also to examine whether higher KAM frequency moderates the association between earnings quality and credit risk.
Findings
Our results provide evidence that the presence of a KAM disclosure requirement moderates the impact of firms with higher credit risk on earnings quality. In addition, there is significant evidence that the higher the frequency of KAM disclosures the greater the moderation impact that is found.
Originality/value
This research investigates whether the disclosure and high frequency of KAMs moderates the effect of credit riskiness on earnings quality. This study improves our understanding of whether more KAMs disclosures would improve earnings quality of firms with higher credit risk. In addition, we also use Beneish M-SCORE, as an alternative earnings quality proxy, to reinforce our empirical results. This markedly differentiates this paper from other studies.

Abstract
Purpose
Product-service innovation (i.e. servitization) is providing opportunities to small and medium-sized enterprises (SMEs) to offer services that are directly coupled to their products. Despite scholarly efforts on servitization in domestic markets, the determinants of international product-service innovation remain unclear. Therefore, this study draws insights from dynamic capability (DC) view and aims to examine the international human capital and international product-service innovation relationship. Specifically, the authors argue that the effect of international human capital on international product-service innovation is mediated by international inter-organizational marketing capability (IIMC) and moderated by international market complexity.
Design/methodology/approach
The authors test the conceptual model using structural equation modeling on a sample of 211 SMEs operating in United Arab Emirates (UAE) – an emerging market economy.
Findings
The results show that IIMC mediates the relationship between international human capital and international product-service innovation. The authors further found that the indirect relationship between international human capital and international product-service innovation is strengthened when international market complexity increases in magnitude.
Originality/value
This study advances the knowledge on international servitization by examining international human capital and IIMC as the determinants and international market complexity as a moderator. Data collection in the UAE contributes to empirical research on international servitization from emerging markets.

Abstract
Purpose
Given the importance of green finance in a discussion of energy efficiency and clean energy, it is critical to evaluate its implications for the growth of renewable energy. This study examines the impact of green finance on renewable energy development in Singapore.
Design/methodology/approach
The dynamic ordinary least squares (DOLS) regression was used in this work to test such a connection.
Findings
Using the DOLS for the period 2000–2020, it was discovered that green finance aids renewable energy development in Singapore. Additionally, the findings revealed that economic growth, oil prices, energy consumption, carbon dioxide emissions and institutional factors are all positively associated with renewable energy growth, resulting in a boost in renewable energy development.
Research limitations/implications
Hence, as a result, the monetary authorities of Singapore, such as financial institutions, non-governmental organisations and corporations, should prioritise renewable energy projects under green finance initiatives to boost renewable energy growth. This may assist in raising investment flows to green projects; hence, accelerating the adoption of renewable energy.
Originality/value
Increased Singapore's initiatives to accelerate green finance have prompted this study to examine the research question of whether green finance has a significant impact on renewable energy growth. Thus, to the best of the authors’ knowledge, this will be the first empirical study to explore the impact of green finance on renewable energy growth in the case of Singapore.
