The purpose of this paper is to examine the influence of clients' trust, opportunism and adaptation on contractual (non)cooperation with a mediating role of coordination in the construction industry.

A questionnaire was used to collect data from employees of the Pakistani construction industry. Smart partial least square (SmartPLS) has been used for analyzing the data of 270 respondents from construction projects.

The results of the SmartPLS indicate that (1) Trust and contract coordination positively while opportunism negatively influence contractor's contractual cooperation. (2) Contract adaptation and contract coordination positively influence the noncontractual cooperation of the contractor. (3) Moreover, contract coordination positively mediates the relationship between trust and noncontractual cooperation, but negatively mediates the relationship between opportunism and contract adaptation and noncontractual cooperation.

The findings of this research suggest several policy implications for administrative authorities, project managers and policymakers. These authorities need to focus on clients' trust, opportunism and adaptation because these factors significantly influence contract coordination and cooperation in the construction industry. Emphasizing these factors will enable project managers to gain economies of scale and mitigate project failure.

To the best of the authors’ search and knowledge, they did not find any study examining the mediating role of coordination between trust, opportunism, adaptation and cooperation in the construction industry. Hence, the present study advances their understanding in the field of project management and construction business.

The main purpose of the current study is to get a better understanding of how the set of crucial categories of nostalgia can negatively impact on green manufacturing intentions in the food industry field, taking three food factories as a case study.

Both qualitative and quantitative data were collected using semi-structured interviews and a questionnaire to fulfill the study’s objectives. The questionnaire has previously undergone testing.

The study results showed that nostalgia categories, especially personal nostalgia, significantly hinder the intention to create green manufacturing system requirements. This, in turn, reduces the intention to produce green products and, consequently, to buy and consume them by an audience that is dominated by nostalgia traits.

This paper’s originality enables the introduction of a brand-new contribution in terms of providing sponsoring facts and information, which goes a long way toward filling the gap in the literature regarding the essential effect that can be achieved by way of the set of nostalgia categories. This includes using a modern look inside the inexperienced manufacturing intentions for processed food products. The current study focused on food sector factories in the Iraqi Kurdistan Region to accomplish this goal.

During the COVID-19 pandemic, an infodemic erupted on social media, leading to a surge in negative disclosure behaviors such as expressing dissatisfaction and releasing negative emotions. By extending the elaboration likelihood model and the Big Five personality theory to the domain of online self-disclosure, we aimed to identify the factors that influence negative disclosure behavior.

We investigated how the features of negative information content, information sources and recipients’ social perceptions influence how social media users disclose negative information. We also examined the moderating roles of personality traits in this process. To validate the model and test our hypotheses, we collected cross-sectional data from 456 social media users.

Empirical results reveal that (1) information overload, topic relevance, attractiveness of information sources, peer approval of negative disclosure and social influence on negative information strengthen the intention to disclose negative information. (2) The perception of social risk weakens the intention to disclose negative information. (3) Openness to experience, extraversion and neuroticism strengthen the relationship between the intention to disclose negative information and actual disclosure behavior.

Our results not only provide new perspectives on the decision-making mechanisms behind negative disclosure behavior but also extend personality research within the context of the dissemination of negative information. Furthermore, it offers insights into negative information dissemination on social media platforms, with significant implications for various stakeholders.

In recent years, the incidence of cardiovascular disease has continued to rise, and early screening and prevention are especially critical. Phonocardiography (PCG) and electrocardiography (ECG), as simple, cost-effective and non-invasive tests, are important tools for clinical analysis. However, it is difficult to fully reflect the complexity of the cardiovascular system using PCG or ECG tests alone. Combining the multimodal signals of PCG and ECG can provide complementary information to improve the detection accuracy. Therefore, the purpose of this paper is to propose a multimodal signal classification method based on continuous wavelet transform and improved ResNet18.

The classification method is based on the ResNet18 backbone, and the ResNet18 network is improved by embedding the global grouped coordinate attention mechanism module and the improved bidirectional feature pyramid network. Firstly, a data acquisition system was built using a MEMS-integrated PCG-ECG sensor to construct a private data set. Second is the time-frequency transformation of PCG and ECG synchronized signals on public and private data sets using continuous wavelet transform. Finally, the time-frequency images are categorized.

The global grouped coordinate attention mechanism and bidirectional feature pyramid network modules proposed in this paper significantly enhance the model’s performance. On public data sets, the method achieves precision, sensitivity, specificity, accuracy and F1 score of 97.96%, 98.51%, 97.58%, 98.08% and 98.23%, respectively, which represent improvements of 3.54%, 3.92%, 4.18%, 4.03% and 3.72% compared to ResNet18. Additionally, it demonstrates a clear advantage over existing mainstream algorithms. On private data sets, the method’s five metrics are 98.15%, 98.76%, 98.08%, 98.42% and 98.45%, further validating the model’s generalization ability.

The method proposed in this paper not only improves the accuracy and efficiency of the test but also provides an effective solution for early screening and prevention of cardiovascular diseases.

This study aims to determine the influence of experiential value, authentic happiness and experiential satisfaction on the behavioral intention of luxury fashion.

Two hundred online questionnaires were collected from customers who rented or bought wedding dresses between 2015 and 2020, with at least one rental or purchase coming from an Indonesian bridal wedding brand that promotes the idea of marriage under Islamic law. The quantitative methodology used in this study was examined using the Structural Equation Model analysis method with the AMOS 22 software.

The results showed that all hypotheses were accepted with significant positive influences, including experiential value in halal fashion on authentic happiness, experiential satisfaction and luxury fashion behavioral intention, authentic happiness in luxury fashion behavioral intention and experiential satisfaction, as well as experiential satisfaction in the behavioral intention of luxury fashion.

The data were collected from respondents who have rented and/or purchased wedding dresses. However, the number of respondents who only rent or who only buy was not identified.

The value of experience in halal fashion needs to be increased. Based on the results of this study, it is hoped that marketers can create effective marketing policies and strategies by paying attention to the value of the consumer’s halal fashion experience because it will affect their authentic happiness, experience satisfaction and luxury fashion behavior intention.

This study has unique originality in measuring the variable of luxury fashion behavioral intention, which was adjusted to the object of research, namely luxury fashion.

This study aims to streamline and enhance the assembly defect inspection process in diesel engine production. Traditional manual inspection methods are labor-intensive and time-consuming because of the complex structures of the engines and the noisy workshop environment. This study’s robotic system aims to alleviate these challenges by automating the inspection process and enabling easy remote inspection, thereby freeing workers from heavy fieldwork.

This study’s system uses a robotic arm to traverse and capture images of key components of the engine. This study uses anomaly detection algorithms to automatically identify defects in the captured images. Additionally, this system is enhanced by digital twin technology, which provides inspectors with various tools to designate components of interest in the engine and assist in defect checking and annotation. This integration facilitates smooth transitions from manual to automatic inspection within a short period.

Through evaluations and user studies conducted over a relatively long period, the authors found that the system accelerates and improves the accuracy of engine inspections. The results indicate that the system significantly enhances the efficiency of production processes for manufacturers.

The system represents a novel approach to engine inspection, leveraging robotic technology and digital twin enhancements to address the limitations of traditional manual inspection methods.

The purpose of this study is to assess the effects of fused filament fabrication (FFF) printing parameters on the surface quality and dimensional accuracy of FFF-fabricated copper green parts using the appropriate filaments. The orthogonal experiments were implemented and the errors in length, width and height were measured and analyzed. The results of range analysis and variance analysis indicated the orders of effect factors. Dissolvent debinding combined with thermal debinding was adopted to remove the binders inside the green part by calculating debinding rate. The influence mechanism of sintering temperatures on the microstructure and shrinkage was elaborated.

The extrusion-based FFF in manufacturing copper parts can overcome shortcomings for high reflectivity and heat dissipation in laser powder bed fusion process at cost-saving and materials saving. This study makes an attempt to prepare copper/binder composite filaments through mixing, extrusion and flowability evaluation.

The results showed that the suitable composite filaments applied for FFF should balance rigidity and plasticity. The combination of printing speed and heating temperature impacts on the surface quality significantly, and the major factor in determining the dimensional accuracy is layer thickness. Two-stage debinding procedure was beneficial for binder removal and sintering process. The higher sintering temperature results in less voids, sizes shrinkage and densified microstructure, which is attributed to the occurrence of sintering neck among the fused copper powders.

The self-prepared copper/binder composite filaments were successfully manufactured using the FFF process. This study provides unique approach and print guidance for fabricating complex structures of pure copper components.

Entrepreneurial boundaries and activities have changed with the widespread use of digital technologies. However, few studies have examined DTA’s effect on opportunity recognition, leading to a vague understanding of this relationship.

Building on the digital entrepreneurship perspective, we explore the underlying mediating mechanism and contextual conditions in the relationship between digital technology application (DTA) and opportunity recognition using data from Chinese entrepreneurial firms.

DTA positively affects opportunity recognition and network strategy mediates the relationship between DTA and opportunity recognition. Environmental uncertainty positively moderates DTA’s indirect effect on opportunity recognition through network strategies.

Our findings contribute to digital entrepreneurship literature by explaining how DTA promotes entrepreneurial firms’ opportunity recognition through network strategies.
