Human induced pluripotent stem cells can be obtained from somatic cells, and their derivation does not require destruction of embryos, thus avoiding ethical problems arising from the destruction of human embryos. This type of stem cell may provide an important tool for stem cell therapy, but it also results in some ethical concerns. It is likely that abnormal reprogramming occurs in the induction of human induced pluripotent stem cells, and that the stem cells generate tumors in the process of stem cell therapy. Human induced pluripotent stem cells should not be used to clone human beings, to produce human germ cells, nor to make human embryos. Informed consent should be obtained from patients in stem cell therapy. 相似文献

This study investigates whether the object-based negative compatibility effect (NCE) originates from involuntary or voluntary inhibition. We hypothesised that both supraliminally presented primes (the prime is a mug with its handle pointing either left or right) and experimental instructions (i.e., ignoring the prime) in previous studies might induce participants to develop a voluntarily inhibitory strategy that is responsible for the object-based NCE. To test this hypothesis, we conducted 3 experiments. Experiment 1 confirmed a suitable paradigm. Experiment 2 altered participants’ strategies by varying the frequency of compatible trials across blocks. The results revealed a significant NCE for the low-frequency condition, which suggested that voluntary strategy might be primarily responsible for the object-based NCE. Experiment 3 combined a free-choice target with an object-based NCE paradigm. The results showed equivalent frequencies and mean response times between the free-choice responses that corresponded to or were opposite from the orientations of the mug handle. Combined with the results of response time quartiles, which revealed NCEs in fast responses (Q1–Q3) but no compatibility effect in slow (Q4) responses, we concluded that the object-based NCE might be primarily based on voluntary inhibition. Moreover, this inhibition might take effect earlier than that of the arrow-based NCE. 相似文献

全球老龄化浪潮正在来临,亲社会行为倾向的年龄差异受到广泛关注。基于第六次世界价值观调查数据集,运用39887个全球成年样本对全球人口亲社会行为倾向的年龄差异进行检验,并探究年龄通过共情关怀和人际信任影响亲社会行为的中介机制。结果表明:全球范围内,年龄显著正向影响亲社会行为倾向,共情关怀不存在显著的年龄差异,人际信任在年龄和亲社会行为倾向之间起显著的中介效应。研究结果对考察亲社会行为倾向的年龄差异及其作用机制具有重要理论价值和实践意义。 相似文献

Although effective leaders are important for reducing employee stress during the COVID-19, limited studies have examined how follower behaviors can influence leader stress and well-being during the COVID-19. This study draws on defeat-entrapment theory to examine how followers' unclear demands during the COVID-19 consequently impact leaders' psychological states and well-being. We conducted a three-wave time-lagged investigation with a sample of 281 leaders in the United Kingdom and found that followers' unclear demands could generate feelings of entrapment in leaders, leading to decreased levels of well-being outcomes in leaders. Importantly, we found that leaders who have higher levels of leadership responsibility during the COVID-19 are likely to feel trapped by followers' unclear demands. They are also likely to face higher levels of feelings of entrapment and impaired well-being compared with leaders who have lower levels of leadership responsibility. We discuss the implications for theories and practices, as well as directions for future research. 相似文献
