Simultaneously, it is easy to pose a threat to the survival and development of project organizations. Organizational resilience can assist in measuring the capability of an organization to cope with disruptions, adverse impacts, and crisis events; however, most existin scales are designed for general business organizations and lack applicability and relevance to project organizations in particular. Therefore, a literature review and field research was conducted, and three project-specific dimensions, personnel, supply chain, and business system, were selected to evaluate organizational resilience in engineering projects. Questions were developed for each dimension from the perspectives of awareness, behavior, and contextualized capability. The scale was initially developed with 17 questions; after exploratory and validation factor analysis, 14 questions were finally developed. The proposed scale was proven to have good reliability and validity and can therefore, provide reference for innovative development in engineering project organizations.","PeriodicalId":70314,"journal":{"name":"工程研究-跨学科视野中的工程","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the potential conflict of different management modes, both parties may fall into a cooperation dilemma. To explore the mechanisms that generate this dilemma, this study takes the delayed opening of the Hongdao high-speed railway station as an example and builds an analysis framework based on the embeddedness perspective using process tracking and in-depth interviews. The study finds that the pressure transmission of external state-owned enterprises and the pressure perception of local governments under political embeddedness lead to the imbalance of cooperative relations. Furthermore, subjective and objective constraints under the embeddedness of local government governance weaken parallel supervision. In embedded cooperation, form embedding and action decoupling create an attention vacuum. Under the influence of multiple mechanisms, the cooperation dilemma is finally formed. This study enriches the understanding of the topology of government-business relations, identifies the potential tension between localized management and project management, and supports the forward-looking governance of the cooperation dilemma in project practice.","PeriodicalId":70314,"journal":{"name":"工程研究-跨学科视野中的工程","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135299076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concurrently, the necessity for environmental protection has further propelled these advancements. The preparation of acrylic acid (methyl ester) from coal-based acetic acid (methyl ester) and formaldehyde by hydroxyl aldol condensation reaction is a green synthesis route in line with China′s energy structure. Catalysts for the synthesis of acrylic acid (methyl ester) by a hydroxyl-formaldehyde condensation reaction of acetic acid (methyl ester) with formaldehyde are reviewed, primarily including catalyst types such as VPO, and metal oxide-loaded catalysts, and ionic liquids. The effects of catalyst preparation methods, addition additives and loading carriers on catalyst structure and activity are also discussed. On the basis of current research, the development trend for catalysts for hydroxyl aldol condensation reactions is prospected.","PeriodicalId":70314,"journal":{"name":"工程研究-跨学科视野中的工程","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47506005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the advancing information age, China’s industrial electricity consumption is growing rapidly; in this context, it is difficult to stably and continuously meet the power demand during peak and trough periods by using green energy as sole electricity supply. Power energy storage technology provides an important means to address this contradiction, among which gravity energy storage technology has become a pertinent research direction for new energy storage methods owing to advantages such as environmental protection, high energy conversion efficiency, low upfront cost, and low requirements for terrain and water sources. Currently, three forms of gravity energy storage exist, including including those utilizing tower cranes, mountains, and abandoned mines, etc .; However, gravity energy storage technology remains in its infancy in China, and the technical and theoretical research on various aspects-such as the principle, safety, and environmental impact of gravity energy storage systems, energy conversion efficiency, power station site selection, heavy block material selection, and applicability–– are inadequate. Based on the energy storage environment in China and abroad, this study analyzed the principle and working mode of the three forms of gravity energy storage. On this basis, the efficiencies of the three energy storage modes were investigated. Finally, from the perspectives of material strength, service life, and formation stability, key recommendations for the selection of materials and power station sites were proposed. The findings provide theoretical support for gravity energy storage in China and address a critical gap concerning the underlying principle and material selection with regard to energy storage technology.","PeriodicalId":70314,"journal":{"name":"工程研究-跨学科视野中的工程","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47834929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the idea and feasibility of rapid logistics transport in the form of a freight tube across the Taiwan Strait is discussed. By investigating the history of pipeline freight and analyzing several intercity and urban underground pipeline logistics scenarios, multiple technical implementations of freight tubes are demonstrated to have the potential to be developed as fixed logistics. Following an assessment of the need for an express logistics tube across the Taiwan Strait based on statistical data on freight transport across the Taiwan Strait, the relationship between the speed of transport and the economic efficiency of an express logistic tube is demonstrated based on the characteristics of logistics in the digital era. Subsequently, from the viewpoint of transportation system theory, establishing a unique organization of freight, smart tubes, caps, and intelligent and safety control systems are proposed to form the express logistics tube system. Finally, five feasible forms of cross-sea tube installation are evaluated and given as a basis for subsequent research.","PeriodicalId":70314,"journal":{"name":"工程研究-跨学科视野中的工程","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41357860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
