Abstract
In recent years, public policymakers in Europe have become increasingly aware of the need to support Europe's failing semiconductor industry. This is an emerging policy area, and this paper examines the current state of the industry in Europe and assesses its potential future. It contends that the competitiveness of the industry will be related to its innovative capacity, especially its capability to engage in processes of open innovation. The industry in Europe is largely located in a number of discrete regional clusters, and the analysis focuses on data collected from a series of interviews with lead representatives of these clusters. The analysis indicates that the challenges facing the industry stem from the structure of the industry in Europe and the structure of the wider European technology industry. It is concluded that policies, such as the introduction of the European Chips Act, are likely to have a limited, or even negative, impact on the types of open innovation–led growth that will improve long-term competitiveness.

With its abundant reserves in the world, carbonate reservoir has become one of the main targets for future oil and gas development. Accelerating the research and development of carbonate reservoirs is thus significant to enhance the world's energy supply capacity. However, there have been some problems in the evaluation of carbonate reservoirs for a long time, such as low description accuracy of fractured-vuggy bodies, diverse flow patterns, and difficult reservoir simulation and prediction. Compared with traditional manufacturing methods, 3D printing is an advanced manufacturing technology of rapid prototyping. It has the characteristics of short manufacturing cycle, not limited by the complexity of parts, material saving and energy saving, and thus has unparalleled advantages in reservoir rock analysis. In this paper, the carbonate core of Yingmaili region in Tarim Basin was taken as the research object, and the uniaxial compression mechanical properties of three small cores printed with different materials were designed and tested by using KINGS-600 3D photocuring printer and photosensitive resin materials. After that, UV-9400S white resin with the highest strength is selected as the printing material of the full diameter core model of the karst cave. Combined with the CT scanning of the formed samples, the control accuracy concerning the cave morphology of the 3D printed samples was tested which adequately proves that flow experiments can be carried out with 3D printed core samples. At last, the article also analyzes the shortcomings of 3D printing technology, and points out the direction for its large-scale application in the field of oil and gas exploitation. This study can especially provide a reference for the application of 3D printing technology in the field of carbonate reservoir development, and ultimately promote the sustainable supply of oil and gas resources.

TikTok is the international twin of China's mobile short video app, Douyin, and one of the fastest growing short video platforms in the world. Owned by Chinese tech giant, ByteDance, TikTok and Douyin share many similarities in terms of appearance, functionality, and platform affordances; however, they exist in radically different markets and are governed by radically different forces. Unlike other popular mobile media platforms in China and internationally, TikTok and Douyin are neither part of the big three tech giants in China nor the big five in the US. This provides an interesting case study to investigate how an emerging internet company adapts its products to better fit divergent expectations, cultures, and policy frameworks in China and abroad. Using the app walkthrough method informed by platformization of culture production theory, this study highlights the similarities and distinctions between these two platforms. We argue the co-evolution of Douyin and TikTok is a new paradigm of global platform expansion that differs from strategies of regionalization adopted by previous major social media platforms. We contribute to platformization theory by developing the concept of parallel platformization to explain ByteDance's strategies for surviving in two opposing platform ecosystems in China and abroad.

In previous studies of the Ultimatum Game (UG), it has been found that proposers do not maximize self-interest by making extremely unfair offers, but instead make relatively fair offers. The main issue is whether or not the proposer's fair behavior is motivated by fear of rejection
or by a concern for fairness. We, therefore, conducted this study to examine the impact on the proposer's decision in the UG when information was obtained about the responder's minimum acceptable offer (MAO). The results show that a high percentage of the proposer's offers were close to the
MAO, indicating that fear of rejection, rather than concern for fairness, accounted for the proposer's positive offer. We also found that Machiavellian personality traits played an important role in the proposer's offering behavior. This indicated that fear of rejection may be more prominently
displayed by people scoring highly in Machiavellianism.
