Since the COVID-19 pandemic, the tourism economy has been seriously affected. China has implemented a direct traveling management mechanism and recovered from the pandemic faster than the rest of the world. However, the COVID-19 situation is complicated and uncontrollable because of the available unclear information including difficult medical terminologies. This study attempts to find the determinants of the travel intention of China’s tourists in the post-COVID-19 epidemic. Along with information overload and perception risk, an expanded research model of the Theory (...) of Planned Behavior was employed to propose the theoretical framework of this study. A survey was conducted among 518 tourists who spend their holiday in Hainan, which is a popular tourist destination in China. The empirical results show that information overload positively and significantly impacted perceived risk. Furthermore, perceived risk negatively affects the intention to travel. Perceived risk also negatively affected the attitude toward traveling. However, response self-efficacy did not have a significant effect on the intention to travel. Finally, based on the analysis results, this study proposes relevant research contributions and practical recommendations with management implications for the travel industries. (shrink)

With the prevalence of the Internet and new media channels, consumer reviews have become one of the main determinants of Consumers’ purchasing decisions. This paper uses the Latent Dirichlet Allocation model to identify the key factors that are of major concern to consumers, including design factors, laptop setup factors, logistics factors, after-sales factors, and user experience factors. And, we classify these factors into product quality factors and supporting service factors for new products. We then explore the relationship between online reviews (...) and purchase decisions under these different factors, and also further explore the impact of interactions between online review metrics on purchase decisions. Our findings suggest that the impact of online reviews on consumer purchase decisions also varies considerably across different consumer focus factors. In addition, we find that the impact of the interaction between online review features is complex. In particular, consumers do not follow the positive guidance and make purchase decisions as we would expect when confronted with a large number of positive emotional polarity online reviews. Meanwhile, the interaction between negative emotional polarity and variance of online reviews had no significant effect on consumer purchase decisions. The variance of online reviews has a limited role in reducing consumer risk perceptions triggered by negative emotional polarity. Our study provides new evidence for the study of the impact of online reviews through text mining. (shrink)

The energy hole is a severe problem for underwater acoustic distributed networks in that it affects the normal operations of the network and shortens the network’s life span. To deal with this problem, a loop-free routing control technique is proposed in this paper. The classical shortest-path routing control method is used to generate multiple disjointed routing tables. The residual energy of the nodes and the changing information of the uplink/downlink matrix are added to the data frames for distribution. The source (...) node specifies the routing path to transmit the data frames based on the changing information, and the relay nodes route the data frames strictly according to the routing path designated by the source node. Besides, the energy consumption of the relay node is saved by replying to the pseudo-ACK frame. Simulation experiments are implemented in four typical scenarios, and the results reflect that the proposed technique could extend the network’s life span by approximately 10% when compared to other mature techniques. Besides, it has no other negative effects on the normal operations of the network. (shrink)

The structure and “metabolism” (movement and conversion of goods and energy) of urban areas has caused cities to be identified as “super‐organisms”, placed between ecosystems and the biosphere, in the hierarchy of living systems. Yet most such analogies are weak, and render the super‐organism model ineffective for sustainable development of cities. Via a cluster analysis of 15 shared traits of the hierarchical living system, we found that industrialized cities are more similar to eukaryotic cells than to multicellular organisms; enclosed systems, (...) such as factories and greenhouses, paralleling organelles in eukaryotic cells. We further developed a “super‐cell” industrialized city model: a “eukarcity” with citynucleus (urban area) as a regulating centre, and organaras (enclosed systems, which provide the majority of goods and services) as the functional components, and cityplasm (natural ecosystems and farmlands) as the matrix. This model may improve the vitality and sustainability of cities through planning and management. (shrink)

Resumo: A prática de 70 anos da Nova China mostra que nosso Partido tem, de forma permanente, valorizado e fortalecido a liderança do trabalho ideológico, fator essencial para que a nação chinesa consiga o salto de rica e poderosa, e consolide continuamente a posição dominante do partido. As sucessivas lideranças coletivas do partido exploraram e inovaram a teoria da ideologia socialista em diferentes períodos da história da China, em vista da situação internacional e doméstica, fornecendo ao PCCh uma base teórica (...) científica e diretrizes de ação para romper as barreiras ideológicas em sua regra de longo prazo. Mao Tsé-Tung fez contribuições históricas significativas para explorar o caminho para o novo socialismo chinês, projeto institucional, inovação teórica e construção ideológica. O objetivo deste estudo é combinar os princípios básicos marxismo com a realidade específica da China, apresentar de forma criativa os princípios básicos e as direções básicas da construção da ideología nacional e elaborar sistematicamente a conotação essencial, a ideologia orientadora, os objetivos primários, a natureza fundamental e o camino de realização da construção da ideología socialista. Este estudo mostra que o primeiro salto teórico da localização da ideología marxista na China lançou uma base sólida para construir um país científico e completo e um sistema ideológico nacional científico e completo.

Transcutaneous auricular vagus nerve stimulation, a non-invasive alternative to vagus nerve stimulation with implantable devices, has shown promise in treating disorders such as depression, migraine, and insomnia. Studies of these disorders with resting-state functional magnetic resonance imaging have found sustained changes in resting-state functional connectivity in patients treated with low frequency taVNS. A recent study has reported reductions in pain scores in patients with rheumatoid arthritis after a 12-week treatment of high-frequency sub-threshold taVNS. However, no studies to date have examined (...) the effects of high-frequency sub-threshold taVNS on rsFC. The objective of this study was to determine whether high-frequency sub-threshold taVNS induces changes in rsFC using seed regions from the cingulate cortex and insula, brain regions that play a key role in interoception and processing of pain. With a single-blind placebo-controlled repeated measures experimental design, rsfMRI scans were acquired before and after 15 min of either sub-threshold taVNS treatment or a sham control. Significant taVNS-related changes in functional connections to the cingulate cortex were detected between the anterior cingulate cortex and right superior temporal gyrus and between the midcingulate cortex and right inferior parietal lobule. In addition, significant changes in functional connections to the insula were detected between the posterior insula and right precuneus and between the anterior insula and right cuneus gyrus. These results suggest that high-frequency sub-threshold taVNS can lead to sustained effects on the rsFC of brain regions involved in interoception and processing of pain in a cohort of healthy subjects. This study lays the foundation for future rsfMRI studies of high-frequency sub-threshold taVNS in clinical populations. (shrink)

For CVaR portfolio nonsmooth optimization problem, we propose an infeasible incremental bundle method on the basis of the improvement function and the main idea of incremental method for solving convex finite min-max problems. The presented algorithm only employs the information of the objective function and one component function of constraint functions to form the approximate model for improvement function. By introducing the aggregate technique, we keep the information of previous iterate points that may be deleted from bundle to overcome the (...) difficulty of numerical computation and storage. Our algorithm does not enforce the feasibility of iterate points and the monotonicity of objective function, and the global convergence of the algorithm is established under mild conditions. Compared with the available results, our method loosens the requirements of computing the whole constraint function, which makes the algorithm easier to implement. (shrink)

◎孔子為何周遊列國？因為沒有一個國君想用儒家治國，他只好到處教書遊說。 ◎秦國用法家統一天下，漢高祖劉邦用道家蓄積國力，直到漢武帝登基，儒家才被注意。 ◎儒學為何從沒人理，轉眼變治國工具？這得從董仲舒的「解釋」說起。 ◎儒學就像作業系統，幾千年來更新過四次版本，孔子的儒學不等於現在的儒學。 作者馬大勇，清華大學、上海交通大學國學特聘教授。 曾被推舉為最受歡迎的中文教授。 在本書中，他將儒家文明分為五個時期： 孔子奠基期、孟子成熟期、兩漢經學期、宋代理學期和明代心學期。 解析儒家思維是如何像電腦作業系統一樣，歷經四次的版本更新， 從原本的中庸之道、民為貴、君為輕的民主思想， 一步步變成君權神授，天人感應， 成為各朝代帝王穩固皇權的最佳推手。 就此儒學變成帝王學，開啟了千年以來人民為皇權奴隸的中央集權體制。 ◎孔子的儒學，是教你如何當君子 《論語》中，仁字出現了104次，禮字出現74次， 孔子的重要理念「中庸之道」，更成為宋元以後科舉考試的必讀書。 這個具有人道主義的思維，為何不被當時的統治者如春秋諸侯或秦國採納？ 因為亂世中，做君子的好處太少，當小人能得到的利益比較多。 ◎孟子是民主思想的啟蒙者，但被後代皇帝刪掉了 孟子思想的最大亮點就是「民為貴，社稷次之，君為輕」， 這套民主思維後來為何會消失？ 因為明太祖朱元璋看到「君為輕」三個字，就把《孟子》一書狠狠摔地上， 刪節版《孟子》就此誕生，往後一百年，學生學到的孔孟儒學知識都是不完整的。 ◎因為董仲舒的「特殊解釋」，從此百家遭罷黜，皇帝獨尊儒術 秦國用法家思想滅六國一統天下，漢高祖劉邦用道家治國，修生養息， 兩大皇權都對儒家思維沒興趣，直到漢武帝劉徹時期， 董仲舒為了拍皇帝馬屁，重新解釋，儒術從此轉化帝王術。 他口中的儒教，跟孔孟闡述的儒學，哪裡不一樣？差在造神。 ◎宋元明清重新詮釋儒學，想當官者必讀四書 宋、元之後，孔子的《中庸》又重新被提起， 因為它教你用大學之道維持國家秩序。 儒學家朱熹更讓《四書集注》成為為官者的必讀聖書。 至於為什麼是宋朝與明朝，跳過了大唐盛世？ 因為東漢黨錮之禍殺害許多知識分子，儒家文化走向低谷； 南北朝興盛佛教；至於唐朝則儒、釋、道並重。 直到韓愈寫的《原道》為儒家文明打下基礎，在宋代發揚光大。 打天下靠武力，龍椅要坐穩就靠統治， 儒家思想如何經過五階段改造，從民主思維變中央集權， 而且延續千年「至今」不墜。 本書特色 儒學為何從沒人理，轉眼變治國工具？這得從董仲舒的「解釋」說起。 孔子的儒學，如何經過五階段改造，從民主思維變中央集權。 名人推薦 淡江大學中文系教授／高柏園.
