In the construction industry, an under researched area of study is how main contractor (MC) sub-contract design responsibilities to sub-contractor (SC). This lack of knowledge is particularly serious in the context of delivery methods such as design and construct where design responsibilities are pushed down the supply chain. In this study, it is aimed to explore which level of design responsibility MCs sub-contract to SCs, for what reasons, and what the impact of sub-contracting decisions is on projects.

A qualitative in-depth multiple case study was conducted. Six sub-contracting cases were examined in two civil engineering projects. In each project, the MCs sub-contracted pre-fabricated beams, reinforcement and railing to SCs. Data collection included document analysis and interviews. A within-case and cross-case analysis was conducted to examine emerging empirical patterns. These patterns were used to elaborate theory and develop propositions.

MCs sub-contracted design responsibilities to SCs as suggested by literature. However, despite that sub-contracting was in keeping with literature, several problems were reported in the cases where MCs involved SCs no earlier than in the construction stage. This is not to be expected according to theory.

This study adds value to the sub-contracting field as it provides new insights in relationships between the level of design responsibilities sub-contracted and the impact of that on projects. The study also revealed new factors such as building information modelling (BIM) interoperability that should get more attention in sub-contracting.

Adopting new technologies to improve supply chain activities and processes is essential due to increasingly complex and dynamic business environments. Particularly in the pharmaceutical industry, high-quality standards must be met, requiring transparency and visibility in the supply chain. This research aims at investigating the implementation of blockchain technology in the supply chain of an Egyptian pharmaceutical company.

The research applies a single case-study approach building on the theoretical underpinnings of transaction cost economics. Twenty-five semistructured interviews were conducted with pharmacies and employees of the case company to identify the blockchain technologies' potential for pharmaceutical supply in Egypt. Further analyzing the frequencies of the codes, the authors elaborate on specific relationships between the observed practices.

The research revealed the potential benefits of adopting blockchain technology. Transaction costs are indeed positively impacted by reduced contracting costs, processing costs and lead times, also ensuring the safe delivery of medications. However, the findings also highlight obstacles related to running costs, awareness and company culture. Regarding supply chain governance, blockchain technology can enhance collaboration within the supply chain as well as with important stakeholders.

Insufficient management of pharmaceutical supply chains (PSC) may affect a company's reputation but also disrupt the patient's healing process due to temperature damage and counterfeit medicines. Blockchain governance, in this vein, can ensure a safer and more reliable supply of pharmaceutical products. For intraorganizational purposes, however, cloud solutions, barcoding and generally digital platforms are rated more frequently than blockchain solutions.

The present study contributes to an advanced understanding how blockchain technology supports PSC, particularly in an emerging country context like Egypt. It thereby confirms and extends previous research as well as adds to the theoretical underpinnings of digitalized supply chains.

The paper is concerned with interpolatory proper orthogonal decomposition (IPOD) methods for nonlinear transmission line circuits. This paper aims to examine several factors that must be considered when applying such model reduction techniques to this kind of circuit.

Two types of POD will be implemented. In each case, the choice of the order of the reduced model and the order of the interpolation space shall be considered. The stability of the models shall be explored.

The results indicate that the order for the reduced model to obtain accurate results depends on the chosen method when considering nonlinear transmission lines. The results also indicate that the structure of the nonlinear transmission line is crucial for determining the stability of the reduced models.

The work compares two IPOD methods and discusses the issues involved in achieving an accurate and stable reduced-order model for a nonlinear transmission line.

The aim of this study was to identify interventions for and mechanisms of the digital transformation of purchasing and supply management (PSM) processes. The digital transformation of tactical and operational PSM processes has often progressed slowly despite the solid knowledge of advanced technologies.

This study used a qualitative exploratory approach based on 14 interviews with PSM executives from firms that are continuously working toward using advanced technologies in their PSM processes but have not yet gained full strategic benefits from digital transformation.

This study formulates five propositions regarding interventions and mechanisms that can positively influence the digital transformation of PSM processes. The main intervention in this regard is the renewal of data infrastructure, including platforms. PSM-related data should meet needs from both tactical and operational viewpoints. When applications serve as a source of data, they support digital transformation. Mechanisms such as supplier measurement and process improvement are outcomes of the digital transformation of PSM processes.

This study highlights the importance of common data sets for tactical and operational purchasing. These purchasing data should be owned and served by a cross-functional team. To create this interoperability, a firm needs global governance of open standards.

This study makes a theoretical contribution to the discussion of what kind of interventions positively influence on the digital transformation of PSM processes. Specifically, this study explains the integration needs of data and applications.

This paper aims to determine the status of the socialist market economy through a logical analysis of the evolution of economic systems in human society.

This paper presents an analysis of uncertainty and the functions performed by different economic systems in managing and resolving it, thereby explaining the evolutionary rationale behind economic system evolution.

Firstly, the socialist market economy empowers the market to play a decisive role in resource allocation, which serves as the foundation for activating individuals' motivation to engage in economic activities. Secondly, the socialist market economy adheres to the basic socialist economic system, which is the basis for the socialist market economy to stabilize the economy and society or to address the risk of economic uncertainty that may trigger macro-level inconsistencies in economic operations. Thirdly, the advantages of a socialist market economy in adapting to economic uncertainties do not arise spontaneously and must be exerted through continuous improvement of the socialist market economy.

The innovation of this paper lies in introducing uncertainty to clarify the logic behind the evolution of economic systems in human society and explaining the typical significance of the socialist market economy and its advantages in accommodating and resolving uncertainty.

Bitcoin is among the highest rated digital crypto-currency in financial investment markets. This technology relies on a backbone of distributed data architecture and peer-to-peer networking model called Blockchain. Unlike the current digital economy, which is governed centrally by financial institution or governments, Blockchain is fully autonomous without any third-party involvement. The exorbitant success of Bitcoin has attracted investors, scholars as well as organizations to peek into this lucrative technology for the possible application to other areas apart from crypto-currency. Blockchain can adopt Smart Contracts, which are digitally enabled contracts that can be executed and enforced fully or partially using pre-defined notions. The aim of this research is to investigate the synergy between Smart Contract and Blockchain to propose a digital framework for an academic paper publication model that has the capability to automate the entire process and challenge the existing system. It can also bring together all the stakeholders under the same system. The proposed model can further hold the stakeholders accountable for breach of contracts and/or reward them for executing the successes of terms pre-configured in the Smart Contract. The proposed model, called Digital Smart Publication or DSP (as referred in the document), is highly secure and ensures balance in distributing rewards to the involved stakeholders while keeping data integrity and security as paramount features.

During the Communist Party of China's endeavors over the past century, China has created “two miracles,” namely, large-scale and rapid economic development and long-term social stability.

The causes for China's achieving the “two miracles” lie in the adherence to the Party's leadership as the political guarantee, the scientific theoretical guidance as the ideological guarantee, the socialist system as well as the national governance system as the institutional guarantee and giving full play of people's creativity under the Party's leadership as the driving force guarantee.

From a political economy point of view, the theoretical logic behind the creation of the “two miracles” is that the combination of the state capacity and the scaling up of markets under the Party's leadership contributes to the rapid economic development and further the long-term social stability based on the financial foundation laid by rapid economic development. The historical experience of the “Two Miracles” can be summed up as the cultivation of state capacity under the leadership of the Party, the synergy and complementarity between the central government and local governments, the combination of development planning and market mechanisms, and the coordination of selective, functional and inclusive industrial policies.

It is necessary to judge future development trends from a medium and long-term development perspective, further promote the co-evolution of the state and the market, reshape the growth regime for high-quality development, fully tap the potential of domestic demand and create a “people-centered” economic development model so as to continue the “two miracles” and achieve a miracle of high-quality development in the second century.

This research is very important to conduct to review government policy on Indonesian contract law that still uses contract law inherited from Dutch product (BW) and review which regulations are to be adapted to current development of contract law. This research’s novelty is that new rules will be found in Indonesian contract law.

This research used normative and empirical methods. Normative research is dogmatic research or one that analyzes legislation using secondary data consisting of primary, secondary and tertiary legal materials. Besides the normative method, the research was also conducted using empirical method through direct interview and observation in some government agencies, such as the Directorate General of Legislation, Ministry of Law and Human Rights (HAM) and Chairman of Legal Product Formation Division, House of People’s Representatives of the Republic of Indonesia and the Civil Law Teaching Association (APHK).

This research found that new Indonesian contract law is very important to give legal certainty and justice to the people, and the contract law must regulate important matters related to the sources of contract besides agreement and law, related to termination, unjust enrichment, negotiation, good faith, public contract and private contract and related to legal act and validity of electronic contract.

The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

Drafting contract law is a relatively heavy duty due to the factor of law pluralism that contains contract aspect in Indonesia such as customary law aspect, Islamic law aspect, regional aspect, international aspect and other aspects. In fact, meanwhile, there is rapid development in the community with regard to business transactions that are also followed with contract law development. Therefore, amendment is needed for the Indonesian contract law to adapt to the people’s need for law, and this change agenda is also addressed to updating the contract law.

Civil law reform, especially contract law, is deemed very important for Indonesia, because based on field fact, people do their business contract by applying contract law that is not yet regulated in the contract law in KUHPerdata; thus, new contract law is needed that regulates important matters related to sources other than agreement and law.

It is very important to conduct this research to review government policy in Indonesian contract law that still uses the contract law inherited from Dutch product (BW) and review what regulations should have been adjusted to current development of contract law. The novelty of this research is that new rules will be found in Indonesian contract law. This research is different from previous researches conducted by Sigit Irianto (2013) and Deviana Yuanitasari (2020), that discuss only on contract law development related only to the good faith principle.

This chapter discusses the growing importance of research-related information in the face of increased complexities and competitiveness within higher education environments globally. It provides some reflections on the importance of institutional research cultures to effectively address these challenges, focussing on the African context, and the role of effective research support through institutional structures such as a dedicated research office. The increasingly strategic role of research management has led to the need for a more active and visionary role in the positioning of institutions by supporting decision-making and contributing to the development and visibility of institutional research portfolios. The authors provide their insights into the scope of research-related information, the need for research offices to perform this strategic function, how these information sets can be applied in reports, evidence-based decisions, institutional showcasing, and enhanced research support. The chapter includes aspects to consider when establishing a research-related information management function within institutions.

During the process of reform and opening-up, the structural transformations of the Chinese economy have two significant leaps forward and demonstrate a process of “rural area–industrialization (urban industry and rural industry)–urbanization” development powered by the main engine of economic growth.

These two leaps forward resulted in transitions of economic structure in China. In the author’s view, structural transformations are closely related to China's economic reforms and can be divided into clear phases.

The structural transformations have two significant leaps forward and demonstrate a process of “rural area–industry (urban industry and rural industry)–urban area development” powered by the main engine of economic growth.

This paper reviews and summarizes the development and structural transformations in China’s economy over the last 40 years. The author believes that China’s economic miracle is accompanied by dramatic changes in its economic structure, which is particularly characterized by the ongoing process of transition from a traditional agricultural economy into a country with high industrial output, from industrialization into urbanization and from a planned economy into a market economy.
