The Dark Side Effect of Entrepreneurial Resilience Diversity on Pivoting: The Role of Team Reflexivity.

Resilience is widely recognized as a form of psychological capital that helps entrepreneurs cope with challenges in the face of adversity by actively adjusting business strategies. Prior research has investigated the effect of resilience on pivoting, which is an important entrepreneurial decision to forgo the original business opportunity and exploit new opportunities. Despite the increasing empirical evidence on the effect of resilience on strategic changes and the pivot, the literature may have overstated the benefits of entrepreneurial resilience while neglecting its potential dark sides. Hence, the current study focuses on the structure of resilience within an entrepreneurial team and introduces the concept of resilience diversity. Drawing from sensemaking theory, we develop a research framework that investigates the dark-side effects of resilience diversity on team reflexivity and pivoting and the moderating effect of environmental hostility. Empirical results from a two-wave survey of 112 entrepreneurial teams in China reveal that resilience diversity negatively affects pivoting by impairing the quality of team reflexivity. Moreover, the mediating effect of team reflexivity is strengthened in hostile environments. These findings contribute to the literature on entrepreneurial resilience, pivot, and team reflexivity, and provide important practical implications for entrepreneurial teams.

Classification and function of γδT cells and its research progress in anti-glioblastoma.

Human peripheral blood T lymphocytes are classified into alpha-beta T (αßΤ) cells and gamma-delta T (γδΤ) cells based on the difference in T cell receptors (TCRs). αßT cells are crucial for the acquired immune response, while Î³Î´Τ cells, though only a small subset, can recognize antigenic substances. These antigens do not need to be processed and presented and are not restricted by MHC. This distinguishes Î³Î´Τ cells from αßT cells and highlights their distinct role in innate immunity. Despite their small number, Î³Î´Τ cells hold significant significance in anti-tumor, anti-infection and immune regulation. Glioblastoma (GBM) represents one of the most prevalent malignant tumors within the central nervous system (CNS). Surgical resection alone proves to be an ineffective method for curing this type of cancer. Even with the combination of surgical resection, radiotherapy, and chemotherapy, the prognosis of some individuals with glioblastoma is still poor, and the recurrence rate is high. In this research, the classification, biological, and immunological functions of γδT cells and their research progress in anti-glioblastoma were reviewed.

Executives' unethical behaviour with directions for future research.

Executives' unethical behaviour is a common phenomenon in business practice and a hot topic for academic research, which has a profound negative impact on the healthy development of our economy and society. In the past two decades, several scholars from different disciplines con-ducted theoretical research and practical explorations on the issue of senior executives' (un)ethical behaviour and achieved certain research results. However, the existing research in this field still has problems, such as a lack of systematic integration of research results, unclear research hotspots and unclear development directions. Thus, the present study through a bibliometric analysis, conducted a content coding of these 428 papers identified from 2000 to 2020, constructed a theoretical framework by inductively identifying the corresponding concepts. By reviewing the progress of existing research topics, this study summarised a research framework of executives' unethical behaviour from the perspectives of the antecedents, the behaviour itself and the consequences of unethical behaviour. The study further proposed future research trends and recommendations for conducting research on executives' unethical behaviour under emerging market scenarios. The research results provide new ideas for developing the theory of executives' unethical behaviour and promote the in-depth development of the research on executives' unethical behaviour in the context of emerging markets.

Biological characteristics of γδT cells and application in tumor immunotherapy.

Human γδT cells are a special immune cell type which exist in small quantities in the body, do not require processing and presentation for antigen recognition, and have non-major histocompatibility complex (MHC)-restricted immune response. They play an important role in the body's anti-tumor, anti-infection, immune regulation, immune surveillance and maintenance of immune tolerance. This article reviews the generation and development of human γδT cells, genetic characteristics, classification, recognition and role of antigens, and research progress in tumor immunotherapy.
