This paper reviews the extant research on Web3.0 published between 2003 and 2022.

This study uses a topic modeling procedure latent Dirichlet allocation to uncover the research themes and the key phrases associated with each theme.

This study uncovers seven research themes that have been featured in the existing research. In particular, the study highlights the interaction among the research themes that contribute to the understanding of a number of solutions, applications and use cases, such as metaverse and non-fungible tokens.

Despite the relatively small data size of the study, the results remain significant as they contribute to a more profound comprehension of the relevant field and offer guidance for future research directions. The previous analysis revealed that the current Web3.0 technology is still encountering several challenges. Building upon the pioneering research in the field of blockchain, decentralized networks, smart contracts and algorithms, the study proposes an exploratory agenda for future research from an ecosystem approach, targeting to enhance the current state of affairs.

Although topics around Web3.0 have been discussed intensively among the crypto community and technological enthusiasts, there is limited research that provides a comprehensive description of all the related issues and an in-depth analysis of their real-world implications from an ecosystem perspective.

The authors are committed to providing the Chinese government with a foundation for making decisions that will protect black land and ensure long-term agricultural development.

Using the grounded theory approach, this study investigates the influencing factors affecting the quality of black land in Northeast China and proposes a hypothetical model for the mechanism of the influencing factors on the quality of black land in Northeast China.

The factors influencing the quality of black land include not only soil quality, ecological quality and environmental quality, but also economic quality and management quality, and can be classified into five categories. There are complex influence relationships between various factors and black land quality, with soil quality, ecological quality, environmental quality and management quality having a positive influence on economic quality. Soil quality, ecological quality and environmental quality are all improved as a result of good management. Black land quality is influenced positively by environmental quality, economic quality and management quality.

The quality of black land is a major concern in terms of food production and long-term agricultural development. The black land in Northeast China was chosen as the subject of this study, and the research findings have some limitations. The next step will be to expand from studying the black land in Northeast China to the black land worldwide.

In Northeast China, the quality of the five dimensions of black land must be improved in a coordinated and consistent manner.

China's agricultural production trusteeship is characterized by the organic link between household operation of small-scale peasant economy and agricultural socialized services, which releases agricultural development vitality and promotes agricultural modernization. As one of the agricultural production trusteeship modes, the whole process trusteeship is suitable for the actual situation of China's aging population and labor force transfer. This paper aims to construct an evolutionary game model containing multistakeholder to explore the behavior decisions through numerical simulation and to provide useful suggestions for the formation of a positive and stable trusteeship relationship and the sound development of the whole process trusteeship of agricultural production.

The paper incorporates village committees, service organizations and farmers into the same research framework, selects “guarantee + dividends” as the income distribution method and applies the evolutionary game method to analyze behavioral choices and evolutionary paths of stakeholders. By constructing the expectation function, establishing the replicator dynamic equations and analyzing the tripartite evolutionary stability strategy, the authors explore the factors that affect the stakeholders’ strategy choice and determine asymptotically stable points and stability conditions.

(1) There is a game relationship among village committees, farmers and service organizations in the whole process trusteeship of agricultural production, asymptotically stable points (0,0,1) and (1,1,1) are obtained through calculation. (2) The proportion of stakeholders' strategy choice, the weight of the whole process trusteeship of agricultural production in the performance appraisal of the village committee, the village committee's supervision cost, the village committee's reputation effect and the penalty for false dividends of the service organization will affect the speed at which the curve representing the tripartite relationship approaches two asymptotically stable points.

The countermeasures proposed in the paper have excellent reference value. (1) For areas that have realized the project: Village committees can solve the trusteeship problems exposed in the initial areas and improve farmers' satisfaction with the project. (2) For areas that have not realized the project: Those regions will receive more experience references and enhance their confidence in this project. The limitation of the paper is that it takes the main grain-producing areas in only the three northeastern provinces of China as the research object. The next research object will be extended to the whole country.

This paper propose strategies for realizing the orderly operation of the whole process trusteeship of agricultural production: first, increase the proportion of stakeholders' strategy choices; second, reduce the village committee's supervision cost; third, increase the weight of the whole process trusteeship of agricultural production in the performance appraisal of the village committee; fourth, improve the village committee's reputation effect; fifth, increase the penalty for false dividends of the service organization.

Agricultural production trusteeship is in its initial stage in China. The interest relationships between stakeholders are not yet clear. The paper innovatively applies the evolutionary game method to the research field of the whole process trusteeship of agricultural production. According to conditions in China, based on ensuring the guaranteed income, the paper introduces the dividend income variable and establishes a tripartite game model of village committees, service organization and farmers. The paper provides suggestions for the orderly and healthy development of China's agricultural production trusteeship and provides experience for the operation of other modes of agricultural production trusteeship.

The purpose of this paper is to identify the motivations to consume ecological foods in alternative food networks (AFNs).

In total, 150 questionnaires were applied; the questionnaire was adapted from Food Choice Questionnaire (Steptoe et al., 1995). Data were analyzed by means of multivariate statistics with factor and cluster analysis. In order to identify statistical differences (p<0.05), Kruskal–Wallis and Mann–Whitney nonparametric tests were performed.

Ten factors or motivations were found: social ecological concern, nutritional content, sensory aspects, certifications, naturalness, specialized consumption, trust in the seller, economic aspects, health and availability. Four groups were obtained and called: citizen consumers, in-process citizen consumers, conscious social consumers with no interest in certifications and conscious pragmatic consumers. It is concluded that differentiated consumers visit these establishments and their motivations are diverse, albeit they concur, to a varying extent, with the objectives of AFNs, finding a mixture of hedonic and ethical motivations.

This sort of works about specific places of consumption as well as specific consumers, in this case ecological, contributes to the development of future social research on other contexts, different consumers and products.

This sort of research has been carried out in various European cities, with a number of foods and over various sales channels; however, at present there is a debate around AFNs and the veracity of their goals. This way, the present work can contribute with an answer to whether the goals match the motivations of consumers.

Organic food consumption is a complex process that makes it difficult for organic food businesses to develop appropriate marketing strategies. This study thus adopted the stimuli–organism–response (S–O–R) model to create a comprehensive framework to understand consumers' organic food purchase decisions.

This study collected 592 valid samples in organic food chain stores and markets by random sampling method. Meanwhile, structural equation modelling was adopted to test hypotheses.

The research findings indicate that consumer preference for natural food was the most important factor for enhancing purchase intention, followed by health consciousness, health risk, attitude towards organic food and trust in labelling. Perceptions of nutritional value positively influenced attitudes towards organic food and trust in labelling, followed by perceptions of environmental effects; conversely, attitudes towards organic food labelling had the least effect on increasing trust in labelling. Attitudes towards organic food labelling was the most important factor influencing positive attitudes towards organic food, followed by consumer perception of environmental protection effects.

This study demonstrates the relative influence of different variables on organic food purchase intention. Compared with consumer attitude towards organic food and trust in labelling, consumers' individual health was the most important factor influencing their purchase intention. As health and naturalness are attractive factors for consumers, the organic food industry can emphasize health protection in their marketing strategies.

The purpose of this paper is to briefly summarize and review the theories and methods of complex structures’ dynamic reliability. Complex structures are usually assembled from multiple components and subjected to time-varying loads of aerodynamic, structural, thermal and other physical fields; its reliability analysis is of great significance to ensure the safe operation of large-scale equipment such as aviation and machinery.

In this paper for the single-objective dynamic reliability analysis of complex structures, the calculation can be categorized into Monte Carlo (MC), outcrossing rate, envelope functions and extreme value methods. The series-parallel and expansion methods, multi-extremum surrogate models and decomposed-coordinated surrogate models are summarized for the multiobjective dynamic reliability analysis of complex structures.

The numerical complex compound function and turbine blisk are used as examples to illustrate the performance of single-objective and multiobjective dynamic reliability analysis methods. Then the future development direction of dynamic reliability analysis of complex structures is prospected.

The paper provides a useful reference for further theoretical research and engineering application.

This study examines the relationship between the emphasis on organic food in Afyonkarahisar's cuisine and the growing demand for healthier and sustainable options. This study aimed to understand the factors influencing the intention to consume organic foods.

This study uses a quantitative research method. It uses scales adapted from previous research to assess the health and safety of organic food's functional, hedonic, and social values. Data were collected using the purposive sampling method, and a sample size of 410 individuals was analyzed using the PLS-SEM method. Measurement and structural models were evaluated to assess validity, reliability, and model fit.

The results indicate that implementing health and safety practices significantly and positively affects perceptions of organic food's functional, hedonic, altruistic, and social values. Additionally, consumers' attitudes toward organic food are greatly influenced by their perceptions of functional and social value, whereas hedonic and altruistic values do not have a significant positive effect.

The results of this study have a beneficial impact on food industry practitioners and policymakers. Emphasizing health and safety practices in producing and promoting organic foods can improve consumer perceptions and attitudes toward organic products. Understanding the importance of practical benefits and social issues can help companies respond effectively to consumer preferences and market organic foods.

This study contributes significantly to the existing literature by investigating the relationship between organic food emphasis and consumer perceptions in the unique context of Afyonkarahisar, a city renowned for its gastronomy. While focusing on Afyonkarahisar provides valuable insights into the specific values that influence consumers' attitudes toward organic food, it is essential to highlight that this research extends beyond the local context to offer broader implications and significance.

With the increasing agility of IT enterprises, it is crucial to identify suitable managerial strategies for controlling information system development (ISD) projects in the new agile working environments. These environments are characterized by the collaborative nature of work and the recurring nature of communication. This study aims to explore how perceived transparency in ISD processes, controlled by transparency strategies, impacts project quality.

In collaboration with a firm that implemented a customized Scaled Agile Framework, questionnaires were distributed to employees involved in ISD projects. The goal was to understand the influence of perceived transparency in ISD processes on project quality.

Our research demonstrates that perceived transparency in ISD processes enhances project quality through knowledge exchange by strengthening goodwill trust among team members. Additionally, transparency improves project quality through client feedback by strengthening competence trust of clients toward the team. Goodwill trust of clients toward the team and competence trust among team members have less impact on project quality enhancement.

This study reveals the nomological network among the perceived transparency, different types of trust among stakeholders, social interactions among stakeholders, and project outcomes in agile ISD environments. This nomological network has been overlooked by previous studies that biased toward top-down, interorganizational communication. It highlights that not all types of trust among stakeholders are involved in the processes through which perceived transparency influences ISD project quality in agile working environments. Additionally, it exposes the limitations of transparency strategies for controlling projects in agile IT enterprises.

This study aims to investigate the impact of perceived values (hedonic and utilitarian), trust and subjective norms on consumers' purchasing intentions of organic food in Saudi Arabia; it also explores the moderating influence of availability on the relationship between the intentions of consumers and their actual purchasing behaviour.

A survey with 236 consumers of organic food in Saudi Arabia was carried out. The convergent and discriminant validity of latent variables was confirmed. The relationships among them were tested using Partial Least Square Modelling (PLS).

The results indicate that utilitarian and hedonic values, trust and subjective norms positively affect consumer purchase intention. They also reveal the moderating effect of availability on the relationship between consumers' purchasing intention and their actual behaviour in the Saudi Arabian context.

The study contributes to knowledge about the relationships among perceived values, trust, subjective norms, availability and consumer purchasing intentions of organic food, and their actual behaviour in an emerging market. The results enlarge the understanding of consumers' purchasing behaviour in the Saudi Arabian organic food market and point out some opportunities for future research.

The study is original in investigating the factors that influence customers' intention and their actual purchasing behaviour toward organic food in Saudi Arabia. It is a first attempt to test the moderating influence of availability on the relationship between purchase intention and actual purchasing behaviour toward organic food products in an emerging market.
