Abstract
The scale of urban land has been expanding because the speed of urban development has increased the population. Thus, certain improvement in planning and construction based on circular economy is required. Industrial resource-based city planning and construction is particularly important based on the aforementioned problems and development background. The development of industrial resource cities in the transformation stage based on the circular economy was considered as the breakthrough point. The development, function, and concept of the new district planning were analyzed in view of the design strategy of the current domestic resource-based urban planning; moreover, the planning principles (integration of regional and harmonious resource constructions and coordinated organization function) that are suitable for resource industrial city were presented. In this study, taking the industrial transformation and resource-based city of Yichun as an example, the infrastructure and the general situation of the new district planning in the future were deeply analyzed. In the light of the functional development and planning structure of the transformation and development planning of resource-based industrial cities, the following planning and development strategies were proposed: the centralized small-scale space should be constructed. Diversion control should be carried out on bicycle lane and motorized lane in new area. The three-dimensional layout of the grid should be applied to the overall planning of the road, and according to the expressway, main roads, secondary roads and ordinary sections, there must be four kinds of traffic system, so as to construct a diversified traffic diversion system. The original industrial land should be extended into a continuous space, and the allocation of new district resources after transformation must be suitable for the development plan of brand strategy, so as to perfect the forestry land of Sun Yue gorge street and transform it into RBD recreational and entertainment community, and build a friendly eco city.

Abstract
Purpose
The primary goal of this article is to review the existing studies and offer clarity regarding the association between social media adoption and youth civic engagement.
Design/methodology/approach
This research systematically summarizes and reviews 42 original articles published from 2010 to 2019 with an objective of offering insightful results. Additionally, a theoretical framework was carefully designed by adopting various conceptions from citizen participation and computer-mediated communication research literature.
Findings
The findings demonstrate that social media usage could generally have a positive correlation with civic participation among younger generations. Moreover, the result also highlights that certain functional features of social media uses including using social media for news consumption and expression could significantly predict civic engagement.
Originality/value
Despite the ever-growing importance of social media technologies, investigations on their differential, nonlinear and even inconsistent effects on civic engagement remain theoretically ambiguous and empirically unsubstantiated. The study represents one of the first scholarly attempts to review, summarize and analyze the extant research evidence from the past ten years.

Abstract
Purpose
The present study aims to investigate the psychometric properties of the picture story exercise (PSE), a tool for measuring implicit motivations in Iran.
Design/methodology/approach
The research method is descriptive correlation and was conducted in two studies. In the first study 24 psychology master’s students were selected by convenience sampling method and tested them to check retest and inter-coder reliability. The second study investigated the correlation between self-reports and the PSE test on a sample of managers. Its statistical population comprised all the managers of a refinery company, 50 people were selected by convenience sampling method. To check the concurrent validity of the PSE test, the participants of the second study, completing the PSE, also completed the needs questionnaire of Steers and Porter (1979).
Findings
The findings showed that the PSE test in the Iranian sample had high retest reliability (0.62 on mean) and inter-coder reliability (0.87 on mean), and, following previous research, it does not show a significant relationship with self-reported motives.
Practical implications
PSE can be used in future research as a tool that has demonstrated its reliability and validity in the Iranian sample.
Originality/value
Measurement of implicit motives is a practical factor for predicting people’s behavior, the necessity of using tools that can accurately evaluate implicit motives is strongly felt. Taking into account the fact that so far, in Iranian samples, implicit motivations have not been measured, therefore, the current research is trying to answer this question, whether one of the most important and prominent tools that were made for this purpose and used in various studies can also be used in Iranian samples.

Abstract
Purpose
Through the scientific and reasonable evaluation of the site selection of the emergency material reserve, the optimal site selection scheme is found, which provides reference for the future emergency decision-making research.
Design/methodology/approach
In this paper, we have chosen three primary indicators and twelve secondary indicators to construct an assessment framework for the determination of suitable locations for storing emergency material reserves. By mean of the improved entropy weight-order relationship weight determination method, the evaluation model of kullback leibler-technique for order preference by similarity to an ideal solution (KL-TOPSIS) emergency material reserve location based on relative entropy is established. On this basis, 10 regional storage sites in Beijing are selected for evaluation.
Findings
The results show that the evaluation model of the location of emergency material reserve not only respects the objective knowledge, but also considers the subjective information of the experts, which makes the ranking result of the location of the emergency material reserve more accurate and reliable.
Originality/value
Firstly, the modification factor is added to the calculation formula of traditional entropy weight method to complete the improvement of entropy weight method. Secondly, the order relation analysis method is used to assign subjective weights to the indicators. The principle of minimum information entropy is introduced to determine the comprehensive weight of the index. Finally, KL distance and TOPSIS method are combined to determine the relative entropy and proximity degree of alternative solutions and positive and negative ideal solutions, and the scientific and effective of the method is proved by case study.

Abstract
Purpose
The purpose of this paper is to investigate how different arrangements, such as lesson structures and patterns of variation, enhance students’ genre awareness, their understanding of genre features of informative text and can generate new learning.
Design/methodology/approach
This is an example of learning study consisting of a design experiment, and embedded in the design was the selected test criteria. The variation theory of learning served as the major guiding principle for the pedagogical design, lesson analysis and evaluation.
Findings
The findings of this study give support to variation theory being a powerful pedagogical tool for improving students’ understanding of informative texts and enabling them to generate new learning. Students in the target group who had more opportunities to encounter the “first contrast, next contrast and last generalisation” pattern of variation performed better than those in the comparison group, who were exposed to the “first generalisation, next contrast and last generalisation” pattern. The pure hierarchical lesson structure used for the target group was found to be more conducive to learning than the mixed structure (sequential–hierarchical structure) used in the comparison group.
Originality/value
Both the lesson structure and patterns of variation and invariance used are extremely important in developing a powerful method of enhancing students’ genre awareness, their understanding of genre features of informative text and to generate new learning.

Abstract
Purpose
The purpose of this paper is to collect new evidence about the efficacy of the pedagogical principles derived from our earlier study on boosting students’ financial literacy, with the aim of providing a theoretically and practically powerful account of how generative learning in the domain of financial literacy can be enhanced.
Design/methodology/approach
This is an example of learning study consisting of a design experiment, which aims to test the conjectures of the variation theory of learning. A total of 156 students who were aged from 14 to 16 years were taught under the three learning conditions which embedded the test criteria, and a total of seven lessons were used by the two participating teachers for each of the classes. To assess students’ appropriation of the object of learning, four tests were conducted, i.e. a pre-test, post-test immediately after the lessons, delayed post-test after six weeks and second delayed post-test after six months.
Findings
This study shows that a systematic use of the pattern of “contrast-fusion-generalization” to deal with the individual core economic concepts identified can help students lay a solid conceptual foundation for developing financial literacy. Furthermore, with the use of the meta-level pattern of “contrast-fusion-generalization” through complex everyday financial problems or situations which transcend the specific concepts, students can make effective use of the core economic concepts learned and transform them organically into one’s analytical framework. This enables students to discern and focus upon the critical aspects of novel financial situations and have a greater likelihood of making well-reasoned and sound financial decisions.
Originality/value
This paper sheds light on the ways in which students’ generative learning in the domain of financial literacy can be enhanced through the conceptual approach grounded in the variation theory of learning.

Abstract
Purpose
Contract incompleteness with deficiency, inconsistency, defectiveness, and ambiguity in contract clauses, which can cause misunderstandings and misinterpretations, may result with disputes in projects. This study aims to investigate contract incompleteness factors with a hybrid fuzzy multi-criteria decision approach.
Design/methodology/approach
Contract incompleteness factors were ranked by fuzzy VIKOR (Visekriterijumska Optimizacija I Kompromisno Resenje) method, and the most significant factors were subjected to fuzzy decision-making trial and evaluation laboratory (DEMATEL) to examine their causal relationships. The study is not limited to ranking the identified factors solely, since their cause-effect interactions are also essential for proper risk management in construction projects.
Findings
Hybrid use of multi-criteria analysis reveals that ambiguity in enforceability including excessive demands and significant amendments in the scope of works are the top two causal contract incompleteness factors, while lack of implementation details and focus of focal point, and insufficient supporting and technical documents are the most affected ones.
Originality/value
Contractual causes of disputes due to contract incompleteness factors other than requirements of the contracts have been rarely investigated in the literature. The research is one of the first studies in the literature investigating the causal relationship among factors in construction contracts, which might lead to project disputes. Findings are expected to improve contract drafting, eventually contributing to effective risk management in construction projects.

Abstract
Purpose
This study investigates the heterogeneous impact of R&D capital market distortions (CMDs) on the quantity and quality of innovation in Chinese firms by exploring key pathways from a dual-arbitrage perspective.
Design/methodology/approach
Using data from Chinese A-share listed companies (2015–2021), we employ a multidimensional fixed effects model to validate the research hypotheses. Under the Systems of National Accounts (SNA, 2008) framework, we use the Bureau of Economic Analysis method to estimate enterprise R&D capital stock and the Cobb-Douglas production function to estimate R&D CMDs.
Findings
Results show that R&D CMDs drive firms toward strategic innovation, emphasizing quantity over quality. Policy arbitrage, including policy catering and rent-seeking, emerges as a pivotal mechanism under R&D CMDs, encouraging firms to prioritize quantity over quality in innovation. High-technology firms and those in the decline stage are more inclined to spearhead strategic innovation within the context of R&D CMDs.
Practical implications
These findings help policymakers promote high-quality innovation in Chinese enterprises by enhancing patent review mechanisms and shifting policies from quantity-driven to quality-oriented goals.
Originality/value
This study enriches the research on factor market distortions and innovation in emerging markets from the perspective of R&D CMDs, based on the “emerging + transitional” comprehensive framework. Unlike previous studies, which generally use enterprise R&D expenditure flow data, we apply the theory of R&D capitalization accounting to the micro-enterprise level under the SNA (2008) framework, enhancing the accuracy of R&D CMD estimations.
