Due to its inexpensive production costs, low stress concentration and maintenance-friendliness, the adhesive bonded pipe joint is frequently utilized for pipe connection. However, further theoretical analysis is needed to understand the debonding failure mechanism of such bonded pipe joints under axial tension.

In this study, based on the bi-linear cohesive zone model, the integrated closed-form solutions were derived by considering the axial stiffness ratio and failure stage to determine the relative interfacial slip, interfacial shear stress and relationship of tension–displacement in the bonded pipe joint.

Additionally, solutions for the critical bonded length and the ultimate load capacity were put forth. Besides, the numerical study was conducted to verify the theoretical solutions regarding the load–displacement relationship. The interfacial shear stress distribution at different failure stages was presented to understand the interfacial shear stress transmission and debonding process. The effect of bonded length on the ultimate load and ductility of pipe joints was also discussed.

The findings in this study can give a reference for the design of bonded pipe joints in their actual engineering applications.

This study aims to understand the sustainable development of small and medium-sized enterprises (SMEs), analysing their current practices in the social, environmental and economic domain.

To fulfil this objective, an exploratory, qualitative approach was adopted, using the multiple case study methodology and focusing on eight cases (SMEs) in Portugal. Data were collected through interviews, since this technique allows proximity and interaction with decision makers and those responsible for firms’ sustainability.

From content analysis of the interviews held, the results show that SMEs are aware of and committed to sustainability and that the external context and some of its particularities have a significant impact on their sustainable development. These SMEs undertake various practices of a social, environmental and economic nature, highlighting especially environmental ones such as efficient resource consumption, using more sustainable resources, recycling waste and waste management.

This study contributes greater knowledge of the phenomenon of SMEs’ sustainable development and identifies practical examples that could increase this firm segment’s awareness of the importance of sustainable practices associated with developing their business.

In this study, new and innovative sustainability practices are presented in the SMEs. The authors can underline that this study contributes to reinforcing the theory about the topic investigated by adding knowledge about sustainable development in the SME context. It deepens knowledge in this scientific area, which can be spread in the scientific community and among SMEs.

The purpose of this paper is to investigate how absorptive capacity mediates the relationship between ambidextrous organizational learning and performance among small and medium-sized enterprises (SMEs).

Based on the resource-based view (RBV) and the dynamic capability approach, this paper uses the resource-capability-performance framework to construct the theoretical model of this study and tests the theoretical model with the questionnaire survey data of 189 SMEs in mainland China.

Ambidextrous organizational learning has different effects on SMEs' performance in terms of survival performance and growth performance. Both exploitative learning and exploratory learning have positive effects on absorptive capacity, and absorptive capacity has positive influences on both the survival performance and growth performance of SMEs. Absorptive capacity plays different mediating roles in the relationships between ambidextrous organizational learning and SMEs' performance: absorptive capacity plays a partial mediating role in the relationship between exploratory learning and SME growth performance, while absorptive capacity plays complete mediating roles in other relationships.

Managers must stress the use of exploratory learning in order to promote SMEs' growth performance. However, to foster both absorptive capacity and SME performance in terms of survival and growth, managers must pay more attention to take advantage of ambidextrous organizational learning. Government as policymakers should create a favorable environment that enable SMEs to benefit much more from the deployment of ambidextrous organizational learning and absorptive capacity.

To the best of authors’ knowledge, this study is the first to theorize and test the mediating role of absorptive capacity in the linkage between ambidextrous organizational learning and SME performance in terms of survival and growth. Additionally, this study also is the first to provide empirical support for the impact of ambidextrous organizational learning on absorptive capacity among SMEs.

Regarding the premises of open innovation (OI) in terms of knowledge sources, this paper aims to discuss how to manage the existing sources of knowledge in supply chains.

An integrative review was developed focusing on studies related to supply chain and OI, seeking to understand the relationships between them, supporting the innovative discussion.

The SIPOC-OI was proposed as a tool to support the management of knowledge sources present in the supply chain, promoting efficiency to the company and improving its innovative capacity.

The conceptual proposal should be empirically verified to understand the management tool's obstacles and benefits for a company's innovation performance. Additionally, it would be useful to understand the results of this proposal in the relationships between agents of the chain, as well as the direction (inbound, outbound or coupled). Additionally, relevant points were highlighted as future agendas.

The point of view based on OI treats the collaboration's aspects and its benefits to agents, which becomes an essential factor in improving the entire chain's integration and performance.

The analysis of the flow of knowledge in supply chains from an OI perspective is an innovation in theory. Besides, the multidisciplinary proposal is expressed in the framework developed as it is based on a tool from engineering. Supply chain competencies/mindset is important to develop OI as well as is the contrary – there is a mutual practical and theoretical relevance between the integration of the concepts.

The purpose of this study to focus on sustainable entrepreneurship practices in small and medium-sized enterprises (SMEs), thus aiming to understand the reasons owners-managers implement them as well as the benefits they provide after considering the three domains of sustainable development: environmental, social and economic.

A qualitative approach was adopted using two Portuguese cases (SME). Data were obtained from interviews and documentary analysis.

From content analysis of the interviews held, the results obtained show that both SMEs studied are concerned about sustainable practices and development. They have competences directing them towards a sustainable entrepreneurship.

The study contributes to understanding the benefits of adopting sustainable entrepreneurial practices in the SME context and helping these firms’ managers reformulate more appropriate and effective strategies and actions to ground these firms in a process of continuous improvement, especially in reducing their environmental footprint.

Although SMEs are numerous and central in the dynamics of the world economy, sustainable entrepreneurial practices have not been studied as a vehicle to reduce the ecological footprint. This holds particularly true for the realm of SMEs.

The aim of this work was to propose a method to prepare composite phosphate conversion coating (CPCC), including ternary phosphate conversion coating (TPCC) and binary phosphate conversion coatings (BPCC), with one-step chemical conversion and to reveal and compare the corrosion resistance between TPCC and BPCC.

In this work, a calcium–manganese–zinc (Ca–Mn–Zn) TPCC was prepared on the surface of magnesium alloy (MA) AZ91D with one-step chemical conversion method; for Ca-Mn-Zn@TPCC, its microstructure was characterized with scanning electron microscope observation and scanning tunneling microscope detection, and its composition was characterized with energy dispersion spectroscopy and X-ray photoelectron spectroscopy analyses. Particularly, the corrosion resistance of Ca-Mn-Zn@TPCC and its comparison with Ca–Mn, Ca–Zn and Mn–Zn BPCCs were clarified with electrochemical and immersion measurements.

Ca-Mn-Zn@TPCC, which was composed of Ca, Mn, Zn, P and O, exhibited a mud-shaped with cracks microstructure, and the average crack width, terrain fluctuation and coating thickness were 0.61 µm, 23.78 nm and 2.47 µm, respectively. Ca-Mn-Zn@TPCC provided good corrosion resistance to MA AZ91D; in NaCl solution, the total degradation of Ca-Mn-Zn@TPCC consumed eight days; corrosion products with poor adhesion peeled out from Ca-Mn-Zn@TPCC-coated MA AZ91D spontaneously. Besides, the corrosion resistance of Ca-Mn-Zn@TPCC was better than that of Ca-Mn@BPCC, Ca-Zn@BPCC or Mn-Zn@BPCC.

The successful preparation of Ca-Mn-Zn@TPCC on MA AZ91D surface confirmed the proposed method to prepare CPCC with one-step chemical conversion was feasible; at the same time, it was further confirmed that for phosphate conversion coating, ternary coating had better corrosion resistance than binary coating did.

The well-being of individuals is an essential issue of sustainability research. This study aims to focus on the particular case of teleworkers and the work conditions which may hinder their well-being. More specifically, this study analyses the impact of social isolation and work overload on the work engagement and life satisfaction of teleworkers during COVID-19 pandemic.

With a sample of 188 workers from the Portuguese banking sector, the authors use structural equations modelling to test a conceptual model. The authors carry out data analysis with partial least squares.

Social isolation and work overload are both negatively associated with the three dimensions of work engagement, namely, vigour, absorption and dedication. In turn, vigour is positively associated with life satisfaction. Social isolation and work overload are indirectly associated with life satisfaction through vigour. Results from multi-group analysis show that the negative relationship between social isolation and dedication is stronger for less senior teleworkers. By contrast, the negative relationship between work overload and dedication is stronger for more senior teleworkers. Additionally, the positive relationship between vigour and life satisfaction is stronger for permanent workers than for temporary ones.

This study tests the assumptions of the job demands-resources under the novel conditions of telework during COVID-19, focusing its ubiquitous conditions – social isolation and work overload. For human resources managers, this study highlights the need to take seniority and job stability in consideration when devising onboarding and working arrangement strategies for teleworkers.

With the usage of social media and Web 2. 0, YouTube channels currently play a pivotal role in supporting a traveler’s destination visit. Travelers create their YouTube channels and share their past experiences in the form of videos, which helps other potential travelers to support their destination visit. The purpose of this paper is to understand how travelers adopt information through YouTube channels and how it influences the traveler’s intention to visit a destination.

A research model was constructed and empirically tested by using a sample of 486 respondents who watch YouTube channels before visiting a destination. Further, the hypotheses of this study were validated with the help of structural equation modeling using partial least squares. The respondents in this study were from Delhi.

This paper found comprehensiveness, relevance, timeliness, source expertise and attitude as the most significant predictors of a traveler’s destination visit intention through YouTube channel adoption. Further, source trustworthiness and accuracy were not found to be statistically significant.

The findings of this paper were based on data taken from the local respondents in Delhi. Further, it analyzed the influence of only seven dimensions on destination visit intention, which could have excluded some important factors that influence tourists’ destination visit intention.

This paper has provided implications for YouTube vloggers and tourists. The result proves that while making decisions regarding destination visit, tourists thinks critically and scrutinize the content of YouTube channels prior to deciding a destination. So, vloggers should provide relevant, comprehensive and accurate destination information through their videos to tourists.

To the best of authors’ knowledge, this paper is the first in the Indian context to examine the adoption of YouTube channels before visiting destinations through information adoption models with additional constructs.

The past 40 years of reform and opening up have seen the role of core competence receive unprecedented attention because of the impact of the new normal economy as well as the pressure of transformation and upgrading. Few Chinese enterprises have effectively constructed core competence, and there is also a lack of strategic perspective and contextual embedding of its construction process in theory. This study aims to analyse the unique contextual characteristics of China in the transitional period and the impact on the core competence construction of Chinese enterprises and proposes its construction mechanism for Chinese enterprises.

Through theoretical deduction and speculation, this paper analyses the process of concept formation, clarifies the concept, analyses its connotations and structure and emphasises its relativity. Based on a review of the theoretical research on the core competence construction process and an analysis of dual contextual impact, this paper puts forward a mechanism for core competence construction.

The results reveal that four specific characteristics of entrepreneurs in balancing and coping with the dual nature of external context constitute the key driving force for a Chinese enterprises’ core competence construction; under the influence of this driving force, the core competence construction mechanism includes process mode, knowledge source, management mode and key success factors.

Approaching it from a Chinese context, this study deepens the concept of core competence; enriches and develops the research related to the core strategic research proposition of its construction; and provides positive significance for Chinese enterprises to effectively build, develop and strengthen core competence and enhance their international competitiveness.

This study aims to focus on understanding how the characteristics of the bed and breakfast (B&B) host responses to online reviews impact the subsequent business performance of review volume, including volume, timeliness and length of responses.

The study constructs a theoretical framework to model for the relationships among characteristics of the B&B host responses, heterogeneity of B&B houses and subsequent reviews. The model is then examined by an econometric model using data from Ctrip.com.

Prompt and lengthy responses to online reviews increase the number of subsequent reviews, and the effects are larger for higher level houses. The main theoretical contribution is to build a model explaining how multiple attributes of the host responses can affect business performance and how these effects are moderated by the class levels of B&B houses, which are empirically tested by real data.

This study highlights managerial implications of host responses for online B&B business practices. For the higher-quality B&B houses, based on price and reviews, lengthy and timely responses are necessary, as tourists expect increased customer service from these hosts.

The research provides insights in understanding the mechanism of B&B host responses on subsequent reviews. To the best of the authors’ knowledge, this is the first study to demonstrate the moderating effect of price and volume of online reviews on responses.
