This article first investigates the status of financial cloud development in smart cities and studies the sustainable development of smart cities. Secondly, it investigates the construction of the evaluation model, using the power of the financial cloud, through exploratory factor analysis, selecting the principal component analysis method to extract the factors, for screening and dimensionality reduction of the indicators, and making hypotheses. We used confirmatory factor analysis to establish the structural equation. The measurement model analyzes and validates the assumptions of the previous stage and finally determines the sustainable development evaluation index system. Then, starting from the scoring coefficient matrix of the exploratory factor analysis of the final model, the variance contribution rate of each common factor is weighted to construct a comprehensive evaluation model to calculate the comprehensive evaluation score. For the comprehensive evaluation score of the sustainable development level of the smart city, SPSS software performs cluster analysis, performs regional clustering, and determines the level of urban development. Finally, by comparing the sustainable development levels of smart cities, the related causes of the gaps are analyzed. Key factors affecting the sustainable development of smart cities are identified, and corresponding countermeasures are proposed.

Coal Supply

Coal is a major source of energy in China. Quantifying China’s coal supply sustainability is essential to track China’s efforts towards sustainable development and achieve carbon neutrality goals. In this research, in addition to availability, economic sustainability, environmental sustainability and technological sustainability, we specially considered health and security, and transport sustainability of China’s coal supply. We select 19 indicators from the above six dimensions to build a coal supply sustainability index and construct a novel optimized comprehensive evaluation model with level difference maximization to evaluate China’s coal supply sustainability. The results showed that the policies issued by the Chinese government have effectively improved coal supply sustainability. China’s coal supply sustainability level has improved significantly, with the figure nearly doubling from 0.338 in 2000 to 0.7004 in 2019. To improve the sustainability of China’s coal supply further fundamentally, it is still necessary to improve energy diversification. Since phasing out China’s coal reliance requires considerable time, the Chinese government needs to introduce more positive and effective policies to such as increase the research and development support for carbon capture, utilization and storage technology, etc. to improve the sustainability of coal supply. The results of this research presented in this paper will have reference value for both promoting the sustainable development of China and other coal-consuming countries in the world.

As one of the most important grain protection policies in China, the minimum purchase price policy prevents the fluctuation of grain output and protects the interests of farmers by regulating the prices of major grain varieties. For developing countries with a shortage of agricultural resources, represented by China, an in-depth study on the implementation effect and public satisfaction of this policy is of great significance for promoting the sustainable development of the grain industry. Based on the interest demands of the government, farmers, grain enterprises and consumers, this paper constructs a policy satisfaction evaluation model based on the Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation. The research shows that the implementation effect of this policy has promoted the sustainable development of China’s grain in four aspects: improving farmers’ enthusiasm for planting, optimizing the structure of supply and demand, reducing the adverse impact of disasters, and ensuring the steady increase of output. However, due to the differences in natural resources and folk customs, the implementation effect of this policy varies in different regions.

Judgment Data

We demonstrated how to perform exploratory factor analysis on situational judgment data of creative personality. Situational judgment test(SJT) has a long history of 80 years and has settled down in industrial/organizational settings for the last 20 years. However, we have not overcome the problem of estimating construct because item scores in SJT contain method effect generated by the scenarios as well as response scores to the substantive questions. We applied Asparouhov and Muthen’s(2009) logic of explorary structural equation modeling(ESEM) to open an approach to estimating common factor structures after controling for the method effect generated by scenarios. Using ESEM, it is possible to specify measurement error correlations in the frame of structural equation modeling and to use exploratory approach to factor analysis on the remaining part of data. As a result we could estimate a four-factor structure on data of 40 items with eight scenarios measuring creative personality of college students.

Education must guide students’ emotional development, not only to improve their skills and help them achieve their maximum performance, but to establish the foundations of a more cooperative and compassionate society. Achieving the Sustainable Development Goals, therefore, implies focusing on emotional aspects as well as financial, social, environmental, and scientific objectives. In this line, the goal of this study is to show how emotional intelligence, which is an essential dimension in the development and management of emotional competences required to build sustainable societies, plays a key role in optimising student’s academic performance in the classroom through compassion and academic commitment. The research model was tested with a questionnaire addressed to 550 students from four higher education institutions and one secondary school. The results of a structural equation analysis confirmed the study hypotheses. Emotional intelligence was shown to be positively related to compassion and higher levels of commitment, which, consequently, led to better academic performance. This finding will encourage interest in developing emotional intelligence, not only for its long-term value in training healthy citizens, but also for its short-term results in the classroom.

Introduction: There is no universal scale for assessing waterpipe tobacco (WT) dependence. We examined the factorial structure and psychometric properties of the Waterpipe Dependence Scale-11 (LWDS-11) among Egyptian WT smokers. Methods: We administered the LWDS-11 during face-interview questionnaires in two cross-sectional surveys among 1490 current WT smokers recruited via purposive quota sampling. Exploratory factor analysis was performed on half of the sample. Confirmatory factor analysis of the resulting model was done using structural equation modelling on the other half. Scale reliability was examined. We assessed convergent construct validity using regression models to examine the association between the adapted dependence scale and factors conceptually expected to be associated with WT dependence. Results: Exploratory factor analysis of the scale yielded eight items (E8-LWDS) supporting a three-factor structure: physical dependence (three items); psychological dependence (three items); and psychological craving (two items). Cronbach’s α were 0.635 for the total scale and 0.823, 0.654, and 0.785 for the three subscales. E8-LWDS was confirmed to have good model fit (comparative fit index = 0.995; root mean squared error of approximation = 0.027). E8-LWDS was independently associated with daily WT smoking, rural residence, being a skilled worker, non-exclusive WTS, smoking ≥ eight WT hagars/day, and measures of perceived behavioral control (self-reported addiction to WT, perceived ability to quit, and previous quit attempts). Conclusion: E8-LWDS showed adequate psychometric properties among this sample of Egyptian current WT smokers, which makes it appropriate for use by researchers and practitioners. Adding items related to perceived behavioral control might enhance the scale robustness.

Η παρούσα διδακτορική διατριβή αποσκοπεί στο να καταγράψει την ικανοποίηση των επισκεπτών από τις παρεχόμενες υπηρεσίες στα θεματικά μουσεία της Ελλάδας, την πρόθεση συμπεριφοράς των επισκεπτών και κατά πόσο τεχνικές του τουριστικού μάρκετινγκ λαμβάνουν χώρα στα θεματικά μουσεία. Έγινε μία προσπάθεια να καταγραφούν οι απόψεις των ανθρώπων των θεματικών μουσείων και η αντίληψή τους σχετικά με το τουριστικό μάρκετινγκ, οι αντιλήψεις των επισκεπτών σχετικά με την εμπειρία που βιώνουν σε ένα θεματικό μουσείο, ο βαθμός ικανοποίησης τους, η υφιστάμενη κατάσταση που επικρατεί στα θεματικά μουσεία της χώρας και οι ενδεχόμενες αλλαγές που μπορούν να προκύψουν με απώτερο σκοπό την αύξηση της επισκεψιμότητας. Ένα αξιοσημείωτο της παρούσας έρευνας, είναι ένας σημαντικός αριθμός προσωπικών συνεντεύξεων με κατοίκους περιμετρικά των μουσείων που ερευνήθηκαν και η προσπάθεια καταγραφής των απόψεων και αντιλήψεων τους για τα μουσεία αυτά.Διενεργήθηκε επίσης μία ποσοτική έρευνα σε επισκέπτες θεματικών μουσείων της χώρας μας αλλά και στο ανθρώπινο δυναμικό που εργάζεται σε πολιτιστικούς οργανισμούς, καθώς και εκπαιδευτικούς. Διακρίνοντας τα μουσεία σε δημόσια και ιδιωτικά, σημαντική ήταν η καταγραφή απόψεων ότι στα περισσότερα δημόσια θεματικά μουσεία τα οποία λειτουργούν κάτω από την επίβλεψη του δημόσιου φορέα, δεν υπάρχουν συχνά δυνατότητες για καινοτομία και πρωτοτυπία. Τα πορίσματα της παρούσας διδακτορικής διατριβής είναι αρκετά σημαντικά λόγω της έλλειψης προηγούμενης έρευνας επάνω στα θεματικά μουσεία της Ελλάδας, από την οπτική του μάρκετινγκ και την αναγκαιότητα αυτού. Η πλειονότητα των ανθρώπων των θεματικών μουσείων με τους οποίους ήρθα σε επαφή, εντοπίζουν την ανάγκη για τεχνικές τουριστικού μάρκετινγκ στα μουσεία καθώς όλοι αντιλαμβάνονται ότι οι επισκέπτες αναζητούν ποιοτικότερες ψυχαγωγικές επιλογές, έχουν περισσότερες απαιτήσεις επισκεπτόμενοι ένα θεματικό μουσείο και ευελπιστούν σε μία βιωματική και διαδραστική εμπειρία που θα τους μείνει αξέχαστη. Σε αυτό το εγχείρημα, συνεργός είναι τα ποικίλα οπτικοακουστικά μέσα των νέων τεχνολογιών που ενισχύουν το βιωματικό χαρακτήρα της επίσκεψης και ερευνώνται στη διατριβή. Η παρούσα διατριβή αποτελεί μία πρώτη προσπάθεια χαρτογράφησης των τεχνικών τουριστικού μάρκετινγκ που χρησιμοποιούν τα θεματικά μουσεία της χώρας , τις σημαντικές ιδιαιτερότητες του τουρισμού που έχουν άμεση επίδραση στην επισκεψιμότητα των θεματικών μουσείων και τέλος προτάσσει ενέργειες και τεχνικές μάρκετινγκ για να δημιουργηθεί ένας ενάρετος κύκλος πολιτισμού - ψυχαγωγίας - οικονομίας. Για την επεξεργασία των δεδομένων της ποσοτικής έρευνας χρησιμοποιήθηκε το στατιστικό εργαλείο SPSS, αναλύθηκαν τα ευρήματα της Διερευνητικής Ανάλυσης Παραγόντων (Exploratory Factor Analysis) και των τεστ αξιοπιστίας με τον δείκτη Cronbach’s Alpha, εφαρμόζοντας και την μέθοδο Μοντελοποίησης Δομικών Εξισώσεων (Structural Equation Modeling, SEM) για τον έλεγχο των ερευνητικών υποθέσεων. Οι ερευνητικές υποθέσεις δημιουργήθηκαν έπειτα από ενδελεχή έρευνα μοντέλων που εφαρμόστηκαν σε προηγμένες μουσειολογικά χώρες, όπως η Ισπανία, η Ιταλία, η Ολλανδία κ.α. και μπορούν να ληφθούν σοβαρά υπόψιν στο κοινωνικό-οικονομικό περιβάλλον της Ελλάδας. Απώτερος στόχος του ερευνητικού μοντέλου είναι εάν ο επισκέπτης θα οδηγηθεί σε μελλοντική επίσκεψη (revisit ) ή θα αποτελέσει ο ίδιος κινητή διαφήμιση word-of-mouth του μουσείου που επισκέφθηκε.Η έρευνα αποτελεί οδηγό για μελλοντικές έρευνες που θα πλαισιώσουν ή θα συμπεριλάβουν τα θεματικά μουσεία για νέες μελέτες, όπως για παράδειγμα πολιτιστικές διαδρομές και είναι ένα χρήσιμο εργαλείο που έρχεται να καλύψει το ερευνητικό κενό που υπάρχει γύρω από το είδος των μουσείων αυτών.
