Artificial Intelligence and Human Intelligence——On Human-Computer Competition from the Five-Level Theory of Cognitive Science
It is generally accepted that the human mind and cognition can be viewed at five levels; nerves, psychology, language, thinking and culture. Artificial intelligence(AI) simulates human intelligence at all five levels of human cognition, however, AI has yet to outperform human intelligence, although it is making progress. Presently artificial intelligence lags far behind human intelligence in higher-order cognition, namely, the cognitive levels of language, thinking and culture. In fact, artificial intelligence and human intelligence fall into very different intelligence categories. Machine learning is no more than a simulation of human cognitive ability and therefore should not be overestimated. There is no need for us to feel scared even panic about it. Put forward by John R. Searle, the"Chinese Room"argument, a famous AI model and standard, is not yet out of date. According to this argument, a digital computer will never acquire human intelligence. Given that, no artificial intelligence will outperform human intelligence in the foreseeable future
Seasonal and inter-seasonal RSV activity in the European Region during the COVID-19 pandemic from autumn 2020 to summer 2022
© 2023 The Authors. Influenza and Other Respiratory Viruses published by John Wiley & Sons Ltd.Background: The emergence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in early 2020 and subsequent implementation of public health and social measures (PHSM) disrupted the epidemiology of respiratory viruses. This work describes the epidemiology of respiratory syncytial virus (RSV) observed during two winter seasons (weeks 40–20) and inter-seasonal periods (weeks 21–39) during the pandemic between October 2020 and September 2022. Methods: Using data submitted to The European Surveillance System (TESSy) by countries or territories in the World Health Organization (WHO) European Region between weeks 40/2020 and 39/2022, we aggregated country-specific weekly RSV counts of sentinel, non-sentinel and Severe Acute Respiratory Infection (SARI) surveillance specimens and calculated percentage positivity. Results for both 2020/21 and 2021/22 seasons and inter-seasons were compared with pre-pandemic 2016/17 to 2019/20 seasons and inter-seasons. Results: Although more specimens were tested than in pre-COVID-19 pandemic seasons, very few RSV detections were reported during the 2020/21 season in all surveillance systems. During the 2021 inter-season, a gradual increase in detections was observed in all systems. In 2021/22, all systems saw early peaks of RSV infection, and during the 2022 inter-seasonal period, patterns of detections were closer to those seen before the COVID-19 pandemic. Conclusion: RSV surveillance continued throughout the COVID-19 pandemic, with an initial reduction in transmission, followed by very high and out-of-season RSV circulation (summer 2021) and then an early start of the 2021/22 season. As of the 2022/23 season, RSV circulation had not yet normalised.Peer reviewe
On the Five Levels of Human Cognition
This paper puts forward the idea of five levels of human cognition: neural cognition, psychological cognition, linguistic cognition, thinking cognition and cultural cognition. It distinguishes the differences between low-order cognition and high-order cognition. Human cognition, that is, high-order cognition, is based on language and characterized by thinking and culture. The five levels of human cognition are divided according to the scientific standard, which means divided according to the level of cognitive process in human mind. This kind of division is the basis of scientific research, too. The cognition of five levels determines the development of cognitive science, and their cross connection determines the development of more interdisciplinary subjects. This paper discusses in detail the present situation and achievements of research on the cognition of five levels, which helps us see not only the relationship between all levels, but also the relations between scientific research on cognitive science and its discipline development. The classification of five levels has important theoretical significance and practical value

Changes in Mental Health of Members of the Chinese Army (1990~2007): A Cross-Temporal Meta-Analysis
This study, by using 142 groups of data from 1990 to 2007 and the method of cross-temporal meta-analysis, researched the changing trend of status of mental health of 108736 members of the Chinese Army along with the change of years. All the data came from 94 related research reports, and all the research reports used SCL-90 (the Symptom Checklist 90) as the testing tool of mental health. The study found that: (1) mental health of members of the Chinese Army steadily improved between 1990 and 2007; (2) during those 18 years, the Interpersonal Sensitivity factor of SCL-90 of Chinese Army members changed most significantly, and the least significantly changed factor was Somatization; (3) Chinese Army members showed evidence of fewest problems on the Photic Anxiety factor, in contrast to the consistent problems indicated by scores on the Obsessive-Compulsive and Interpersonal Sensitivity scales; (4) Chinese Army members from single-child families (N =1,944) showed significant lower evidence of positive mental health than soldiers from multiple child families (N =2,649); (5) The mental health of soldiers from non-agricultural backgrounds (N =7,808) was less positive than that of soldiers from agricultural households(N =11,459); (6) Chinese Army members with senior high school education level (N = 10,189) had less positive mental health than those with junior high school (N = 8,407) or university education (N = 863)
Reversibility in Chinese word formation influences target identification
We recorded event-related brain potentials during the processing of visually presented compound words in Mandarin Chinese. We capitalized on a particular characteristic of Chinese word formation, where two constituents can be combined in two different orders (A + B or B + A), yielding distinct meanings-so-called "reversible words". By investigating the impact of structural reversibility on the processing of compounds in Chinese during a lexical decision task, the present study revealed a pronounced difference between reversible and non-reversible words. Analyses revealed a more enhanced negativity (N400) for reversible words, reflecting demands during semantic processing, followed by a P300-like deflection for non-reversible words, which we interpret with respect to the ease of target identification due to target discriminability. The findings indicate that both character combinations (A + B, B + A) as well as access to the individual constituent meanings result in interference during the processing of reversible and non-reversible words. They reveal that combinatorial processes are affected by demands arising from competing representations (N400), and more importantly, that this impacts the task-relevant cognitive processes required in the current word/non-word identification task (P300). The observed P300-like potential suggests that the allocation of attentional resources is intertwined with combinatorial operations
Creative organizational climate of schools, general self-efficacy, creativity self-efficacy, and cultural efficacy of teachers
The aim of the present study is to examine the characteristics of the creative organizational climate of Chinese schools, teachers’ general self-efficacy, creativity self-efficacy and cultural efficacy of own culture and to analyse the relations between these four core variables. Our analyses revealed significant teaching duration differences, age differences and a significant two-way school × teaching subject interaction in creative organizational climate as well as significant gender difference in general self-efficacy. Results of a path analysis revealed significant path coefficients were from creative organizational climate to cultural efficacy of own culture, general self-efficacy, from general self-efficacy to cultural efficacy of own culture and creativity self-efficacy, and from cultural efficacy of own culture to creativity self-efficacy. Analyses only revealed evidence for an indirect pathway from creative organizational climate to creativity self-efficacy. Results suggest the development of interventions to increase creative organizational climate and enhance general self-efficacy in educational practices
Fgr contributes to hemorrhage-induced thalamic pain by activating NF-κB/ERK1/2 pathways
Thalamic pain, a type of central poststroke pain, frequently occurs following ischemia/hemorrhage in the thalamus. Current treatment of this disorder is often ineffective, at least in part due to largely unknown mechanisms that underlie thalamic pain genesis. Here, we report that hemorrhage caused by microinjection of type IV collagenase or autologous whole blood into unilateral ventral posterior lateral nucleus and ventral posterior medial nucleus of the thalamus increased the expression of Fgr, a member of the Src family nonreceptor tyrosine kinases, at both mRNA and protein levels in thalamic microglia. Pharmacological inhibition or genetic knockdown of thalamic Fgr attenuated the hemorrhage-induced thalamic injury on the ipsilateral side and the development and maintenance of mechanical, heat, and cold pain hypersensitivities on the contralateral side. Mechanistically, the increased Fgr participated in hemorrhage-induced microglial activation and subsequent production of TNF-α likely through activation of both NF-κB and ERK1/2 pathways in thalamic microglia. Our findings suggest that Fgr is a key player in thalamic pain and a potential target for the therapeutic management of this disorder
