What motivates firms from emerging economies to go internationalization?

With advent of economic globalization, internationalization has become one of the most important strategies for firms to achieve sustainable growth. Based on the empirical research in the Yangtze River Delta region in China, the method of Correspondence Analysis was employed to study the motivations for going internationalization of Chinese enterprises. The main findings include: (1) the motivations for internationalization of enterprises depend on their scale, and largesized enterprises are mainly motivated by the purpose of creating global brands and enhancing domestic reputation; (2) the ownership of enterprises has obvious influence on their motivations for going internationalization, and (3) enterprises in different industries also show different levels of motivation for internationalization

UniSumm and SummZoo: Unified Model and Diverse Benchmark for Few-Shot Summarization

The high annotation costs and diverse demands of various summarization tasks motivate the development of few-shot summarization. However, despite the emergence of many summarization tasks and datasets, the current training paradigm for few-shot summarization systems ignores potentially shareable knowledge in heterogeneous datasets. To this end, we propose \textsc{UniSumm}, a unified few-shot summarization model pre-trained with multiple summarization tasks and can be prefix-tuned to excel at any few-shot summarization task. Meanwhile, to better evaluate few-shot summarizers, under the principles of diversity and robustness, we assemble and release a new benchmark \textsc{SummZoo}. It consists of $8$ summarization tasks with multiple sets of few-shot samples for each task, covering diverse domains. Experimental results and analysis show that \textsc{UniSumm} outperforms strong baselines by a large margin across all sub-tasks in \textsc{SummZoo} under both automatic and human evaluations and achieves comparable results in human evaluation compared with a GPT-3.5 model.Comment: ACL2023 main conferenc

Managerial drivers of Chinese labour loyalty in international construction projects

Organization performance is becoming ever more dependent on employee loyalty in the international con­struction projects. However, the improvement of construction labour loyalty on construction sites remains a largely neglected measure for reducing their turnover and improving their productivity. The purpose of this study was to quan­titatively investigate the managerial drivers of labour loyalty, including macro-environment of the project host country, organizational living environment, job system, rewards, and communication, and to explore the significance of satisfac­tion as a mediating variable in the relationship between the managerial drivers and construction labour loyalty. First, hypotheses on the relationships between construction labour loyalty, satisfaction and the five managerial drivers were proposed. Second, structural equation modelling was adopted to test these hypotheses. Finally, the results demonstrated two types of influence paths: (1) macro-environment, job system and communication have significantly direct effects on construction labour loyalty, (2) mediated by satisfaction, organizational living environment and rewards offer posi­tive indirect effects on construction labour loyalty. The first type of path serves as a long-term strategic orientation for improving labour loyalty. The second type of path is a tactic for short-term goals of labour loyalty enhancement. The research results can contribute to the body of knowledge of human resource management and the practice of enhancing labour productivity through improving construction labour loyalty in the context of international construction projects

JIB-04 has broad-spectrum antiviral activity and inhibits SARS-CoV-2 replication and coronavirus pathogenesis

Pathogenic coronaviruses are a major threat to global public health. Here, using a recombinant reporter virus-based compound screening approach, we identified small-molecule inhibitors that potently block the replication of severe acute respiratory syndrome virus 2 (SARS-CoV-2). Among them, JIB-04 inhibited SARS-CoV-2 replication in Vero E6 cells with a 50% effective concentration of 695 nM, with a specificity index of greater than 1,000. JIB-04 showe

Cholesterol 25-hydroxylase suppresses SARS-CoV-2 replication by blocking membrane fusion

Cholesterol 25-hydroxylase (CH25H) is an interferon (IFN)-stimulated gene that shows broad antiviral activities against a wide range of enveloped viruses. Here, using an IFN-stimulated gene screen against vesicular stomatitis virus (VSV)-SARS-CoV and VSV-SARS-CoV-2 chimeric viruses, we identified CH25H and its enzymatic product 25-hydroxycholesterol (25HC) as potent inhibitors of SARS-CoV-2 replication. Internalized 25HC accumulates in the late endosomes and potentially restricts SARS-CoV-2 spike protein catalyzed membrane fusion via blockade of cholesterol export. Our results highlight one of the possible antiviral mechanisms of 25HC and provide the molecular basis for its therapeutic development
