This paper aims to present an investigation on flight quality analysis and design of tilt-rotor aircraft combined with corresponding flight quality specifications.

From the perspective of modal characteristics of tilt-rotor aircraft, it focuses on the analysis of the change rules of the longitudinal short-term motion mode, lateral roll convergence mode, spiral mode and Dutch roll mode. Then, the flight quality design research is carried out using the explicit model tracking control method. The quantitative relationship between flight quality requirements and explicit model is established. Accordingly, the closed-loop flight quality of XV-15 tilt-rotor aircraft is evaluated.

The stability of spiral mode is the result of the interaction of various aerodynamic derivatives and spiral instability occurs in helicopter mode. The other motion modes are stable in full flight mode and meet the requirements of level 1 specified in ADS-33E-PRF and MIL-F-8785C flight quality specifications. There is a quantitative relationship between flight quality requirements and explicit model, and the flight quality of tilt-rotor aircraft is improved through the explicit model tracking control method.

The presented analysis results showed the influence of motion modes and flight quality and the effectiveness of explicit model tracking control method in flight quality improvement, which could be considered as new information for further flight quality design of tilt-rotor aircraft.

The originality of the paper lies in the proposed design and analysis method of the flight quality of tilt-rotor aircraft from the direction of the influence of its aerodynamic derivatives and motion modes.

Based on an institutional approach to explaining firms’ internationalisation, this paper aims to empirically investigate the role of Export Promotion Programmes (EPPs) in moderating the influence of export barriers perceptions on small and medium enterprises’ (SMEs) propensity to export.

The study uses evidence from Algeria, the largest North-African country. The data were collected using an online questionnaire, targeting SMEs operating in the manufacturing sector. The study considers the influence of procedural, informational, environmental and functional barriers on export propensity, to uncover the moderating role of trade missions, trade shows and export seminars and workshops on such relationships. To examine these links, five main hypotheses are proposed and tested through a non-linear partial least squares structural equation modelling on a sample of 128 Algerian SMEs.

The results show that while internal barriers decrease firms’ export propensity, EPPs including trade fairs and shows may independently pose either a positive or negative influence on such relationships.

The study confirms the applicability of the institutional perspective to explaining firms’ internationalisation. More importantly, the present study highlights the role of EPPs in moderating the influence of export barriers perceptions on SMEs’ international market entry, a role neglected by the extant empirical literature.

The current findings hold important implications to export promotion organisations operating in African countries. Notably, the results reveal that some programmes could have a negative influence if they are not delivered appropriately.

This study offers a rare focus on the moderating role of EPPs in the relationship between export barriers and export propensity, within the setting of a North-African country.

Due to the increasing size and complexity of construction projects, construction engineering and management involves the coordination of many complex and dynamic processes and relies on the analysis of uncertain, imprecise and incomplete information, including subjective and linguistically expressed information. Various modelling and computing techniques have been used by construction researchers and applied to practical construction problems in order to overcome these challenges, including fuzzy hybrid techniques. Fuzzy hybrid techniques combine the human-like reasoning capabilities of fuzzy logic with the capabilities of other techniques, such as optimization, machine learning, multi-criteria decision-making (MCDM) and simulation, to capitalise on their strengths and overcome their limitations. Based on a review of construction literature, this chapter identifies the most common types of fuzzy hybrid techniques applied to construction problems and reviews selected papers in each category of fuzzy hybrid technique to illustrate their capabilities for addressing construction challenges. Finally, this chapter discusses areas for future development of fuzzy hybrid techniques that will increase their capabilities for solving construction-related problems. The contributions of this chapter are threefold: (1) the limitations of some standard techniques for solving construction problems are discussed, as are the ways that fuzzy methods have been hybridized with these techniques in order to address their limitations; (2) a review of existing applications of fuzzy hybrid techniques in construction is provided in order to illustrate the capabilities of these techniques for solving a variety of construction problems and (3) potential improvements in each category of fuzzy hybrid technique in construction are provided, as areas for future research.

Globalisation is generally defined as the “denationalisation of clusters of political, economic, and social activities” that destabilize the ability of the sovereign State to control activities on its territory, due to the rising need to find solutions for universal problems, like the pollution of the environment, on an international level. Globalisation is a complex, forceful legal and social process that take place within an integrated whole with out regard to geographical boundaries. Globalisation thus differs from international activities, which arise between and among States, and it differs from multinational activities that occur in more than one nation‐State. This does not mean that countries are not involved in the sociolegal dynamics that those transboundary process trigger. In a sense, the movements triggered by global processes promote greater economic interdependence among countries. Globalisation can be traced back to the depression preceding World War II and globalisation at that time included spreading of the capitalist economic system as a means of getting access to extended markets. The first step was to create sufficient export surplus to maintain full employment in the capitalist world and secondly establishing a globalized economy where the planet would be united in peace and wealth. The idea of interdependence among quite separate and distinct countries is a very important part of talks on globalisation and a significant side of today’s global political economy.

The objective of this research is to know the degree of influence that strategic planning (SP) exerts on the tangible and intangible results of business microenterprises in the state of Guanajuato, Mexico.

The methodological design was quantitative, explanatory, observational and cross-sectional, where a sample of 407 young leaders of microenterprises from the state of Guanajuato, Mexico, was obtained. To evaluate hypotheses, a structural equation model (SEM) was developed. Regarding the goodness and adjustment indices of the SEM, they were absolutely acceptable.

The results obtained through Pearson’s correlation show that there is a positive and significant relationship between SP and the tangible and intangible results of microenterprises. In addition, through the results obtained with the SEM model, it is statistically demonstrated that SP positively and significantly influences the tangible and intangible results of microenterprises in the state of Guanajuato, Mexico.

In this research, only SP was valued as a variable that intervenes in the process of achieving tangible and intangible results to achieve the business objectives of entrepreneurial microenterprises in the state of Guanajuato. It is essential to point out that other variables that intervene in the process must be considered to generate tangible and intangible results. It is recommended to carry out further research under these variables to identify strategies for improving entrepreneurial microenterprises for their growth, sustainability and rapid positioning in a highly competitive market.

SP represents one of the tools to achieve the success of microenterprises through tangible and intangible results. However, microenterprises show a need to involve the use and application of SP to define clear indicators that contribute to obtaining satisfactory tangible and intangible results.

The findings are relevant and of great value, because there is currently not enough research that focuses on the variables analyzed, in this sense, SP and the tangible and intangible results of young entrepreneurial leaders of microenterprises in the Mexican context. The limitations of this study lie in the low participation and interest of young microenterprise entrepreneurs in the state of Guanajuato, Mexico.

This paper aims to empirically investigate the relationship between service quality (SQ) in heritage tourism, destination attachment (DA), and electronic word-of-mouth (eWOM) intention.

This study followed cross-sectional survey-based research design and surveyed 327 foreign tourists visiting the Golden Triangle, a heritage tourist circuit in India through mall interception method. The data were analysed using structural equation modelling.

The results reveal that heritage SQ has a significant positive effect on DA and eWOM intention and DA has a significant positive effect on eWOM intention.

The research findings make the theoretical and practical contribution in the domain, focussing explicitly on heritage tourism, in which such relation has not been studied yet, in sense of the foreign tourists.

This study aims to analyze the mediating role of data analytics management capability (DAMC) in the relationship between supply chain integration (SCI) and supply chain agility, adaptability and alignment (Triple-A). It also studies the role of Triple-A supply chains in performance improvement. We develop and present a model based on our proposition and informed by the dynamic capabilities perspective.

The authors employ meta-analytic structural equation modeling to test the proposed model by analyzing reported statistics of 117 published studies.

This study’s results describe why some prior research findings are contradictory. For example, researchers have posited mixed findings on the impact of SCI on agility. The results show that SCI and agility do not have a significant direct association, and DAMC mediates their indirect relationship.

The impact of SCI on performance is debatable. SCI permits access to shared resources for competitive advantage; conversely, SCI-induced rigidity may reduce supply chain agility and adaptability. Informed by dynamic capabilities theory, the authors demonstrate that DAMC positively mediates the impact of SCI on performance.
