Open pitaya (Stenocereus thurberi) flowers were marked at 10, 20, 30 and 40 days after floration (DAF). When fruit were formed, they were collected from each of the dates with the objective of evaluating physical, physiological and quality changes before and after harvest. In fruits with different DAF, the analyses of fruit size (diameter and length), weight, density, firmness, color in pulp and peel (L*, a* and b*), respiration rate (CO₂) and ethylene production were carried out. In the case of ripe and overripe fruit, in addition to the variables mentioned above, pH, percentage of total soluble solids TSS and total acidity (% citric acid equivalents) were evaluated. Fruit with 40 DAF were stored for up to 14 days at 25 ℃ and 80% RH to evaluate daily changes in respiration rate and ethylene production. It was found that during development the fruit tended to grow more in length than in diameter. In color, the best indicators of changes during fruit development were the parameters L* and b* for peel and for flesh L* and a*. For firmness in pitaya fruits, no significant differences were found with the methodology used. Changes in ethylene production and respiration rate during storage and development showed the usual behavior of climacteric fruits. Pitaya fruits with 40 FDD presented quality characteristics similar to those accepted by the consumer for this type of fruit. It is concluded that it is possible to evaluate the different stages of development in DDF of pitaya fruit based on the changes of the color space variables L*, a* and b*, in addition to the fact that the fruit follows the classical climacteric behavior.

In higher education, mental health education is a complex task that involves many educational factors. From the perspective of psychological education, the basic tasks and value pursuits of university mental health education and curriculum ideological and political education are the same. Both are student-centered, providing a basic guarantee for the integration of the two. Currently, some universities are facing issues such as the need to clarify the concept of "psychological education", the trend towards value neutrality in mental health education, and the need to improve the quality of the psychological education team. In response to this situation, universities should integrate educational factors, provide clear value guidance, strengthen integrated education, improve the overall quality of the education team, continue to promote the ideological and political construction of psychological health education courses in universities, and achieve new breakthroughs.

The combination of special education on civil law and legal education in ideological and political courses can further enrich the content of legal education, improve the rigor of legal education, and guide students to flexibly apply legal knowledge. This article mainly focuses on the importance of integrating civil code thematic education into the rule of law teaching of ideological and political courses, the effective path of integrating civil code thematic education into the rule of law teaching of ideological and political courses, and the precautions for integrating civil code thematic education into the rule of law teaching of ideological and political courses. It focuses on exploring new paths for the rule of law teaching of ideological and political courses in conjunction with civil code thematic education, and hopes to provide some reasonable suggestions, Highlighting the importance of legal education in ideological and political courses, we aim to attract and cultivate students through rich and colorful legal education in ideological and political courses.

This research aims to investigate how technological innovation influences social sustainability via the mediating role of organizational innovation and digital entrepreneurship. This investigation employed a quantitative research approach and used data from survey questionnaires based on a set of suppositions evaluated using structural equation modeling. A total of 320 respondent companies from digital provider companies in Thailand. The findings of the research expose that technological innovation has a positive effect on organizational innovation and digital entrepreneurship. Both serve as mediators in the correlation between technology innovation and social sustainability. Moreover, this research will be beneficial for businesses that are implementing new technologies and innovation, considering their role in attaining both environmental and social sustainability.

Chinese multinational enterprises (MNEs) have increasingly engaged in outward foreign direct investment in recent years, and particularly into the infrastructure sector of developing economies. This has been prompted by the infrastructure-led economic integration plan of China’s Belt and Road Initiative. However, such collaboration faces many challenges. Infrastructure projects are often undertaken in industries, countries, and regions posing particular and difficult challenges, and with divergent, often conflicting interests, with the ensuing conclusion that the MNE is simply exploiting the project and not delivering value to the host country. Overall, not only does the infrastructure project have to be well-functioning with expected returns (or savings) realized, but these projects face close scrutiny from local communities, labor, opposition parties, neighboring countries, and various international bodies and nonprofits, requiring delicate handling of the principals involved. The unfolding of these issues and their management by the multinational are examined through an in-depth longitudinal case study. The data are drawn from major participants and stakeholders around a leading Chinese MNE and the mega project of the construction of a major hydropower plant in Pakistan.
