This study investigated the effect of obstructive sleep apnea on the neural mechanism of visual perception. A preliminary case-control study was conducted. Seventeen patients with moderate to severe OSA in the sleep center of Civil Aviation General Hospital and 20 healthy controls matched for age, sex, and education were recruited. The participants accepted the perceptual contour integration task, compared the differences in behavioral indicators between the two groups, and compared the differences in electroencephalography data between the two groups through event-related (...) potential technology. The groups did not differ significantly in age and gender, but they differed significantly in body mass index. The groups were not statistically different in terms of sleep structure and total sleep time. AHI, sleep efficiency, and minimal SaO2 value in the OSA group were significantly different from those of the control group. The results showed that the average reaction time of the OSA group was significantly longer than that of the healthy control group in the contour integration task. There was no significant difference in the accuracy rate. The results of EEG showed that the amplitudes of N100 of the OSA group were significantly higher than those of the control group at O1, Oz, and O2 electrodes. There was no significant difference in latency between the two groups. At the FCz electrode, the amplitudes of N200 of the OSA group were significantly higher than those of the control group. Therefore, we concluded that in the early stage of the perceptual integration task, although the neural response activity of patients with moderate and severe OSA was not accelerated, they need to call on more psychological resources, activate more neurons in the contour global recognition processing stage, and the compensatory effect of frontal lobe appeared in the stage of visual perception.

This article examines the phenomenon of the “global circulation of low-end expertise” through an exploration of the social dynamics surrounding American oil drillers who migrated from the Pennsylvania oil region to British colonial Burma during the early 1900s to the mid-1930s. These working-class drillers, with practical knowledge in oil drilling acquired through familial and community networks, played a crucial role in operating mechanized oil wells and providing geological expertise in colonial Burma. Positioned between labor-intensive agricultural economies in colonial Asia and (...) the higher echelons of British colonial society, these drillers occupied an intermediate social location. Despite their indispensable expertise, they were marginalized due to their lower social standing, leading to their expertise being disregarded by their superiors and forgotten over time. By understanding the complexities of the “global circulation of low-end expertise,” this study sheds light on the social construction and erasure of the expertise held by these working-class drillers, revealing overlooked aspects of global histories of science and labor and highlighting the need to reassess dominant historical narratives on knowledge-labor.

Social media offers a platform for diffused stakeholders to interact with firms—alternatively praising, questioning, and chastising businesses for their CSR performance and seeking to engage in two-way dialogue. In 2014, 163,402 public messages were sent to Fortune 200 firms’ CSR-focused Twitter accounts, each of which was either shared, replied to, “liked,” or ignored by the targeted firm. This paper examines firm reactions to these messages, building a model of firm response to stakeholders that combines the notions of CSR communication and (...) stakeholder salience. Our findings show that firm response to a stakeholder on social media is positively and most significantly associated with what we refer to as the stakeholder’s connective power but negatively associated with the firm’s own connective power. To a lesser extent, firm response is positively associated with the stakeholder’s normative power but negatively associated with the firm’s own normative power. Firm response is also shown to be positively associated with stakeholder urgency in terms of both the originality of a stakeholder message and the expression of positive sentiment. (shrink)

PurposeThe purpose of this study was to introduce an orthogonal experimental design to improve the efficiency of building and optimizing models for freezing of gait prediction.MethodsA random forest model was developed to predict FOG by using acceleration signals and angular velocity signals to recognize possible precursor signs of FOG. An OED was introduced to optimize the feature extraction parameters.ResultsThe main effects and interaction among the feature extraction hyperparameters were analyzed. The false-positive rate, hit rate, and mean prediction time were 27%, (...) 68%, and 2.99 s, respectively.ConclusionThe OED was an effective method for analyzing the main effects and interactions among the feature extraction parameters. It was also beneficial for optimizing the feature extraction parameters of the FOG prediction model. (shrink)

A generalization of a Burridge-Knopoff spring-block model is investigated to illustrate the dynamics of transform faults. The model can undergo Hopf bifurcation and fold bifurcation of limit cycles. Considering the cyclical nature of the spring stiffness, the model with periodic perturbation is further explored via a continuation technique and numerical bifurcation analysis. It is shown that the periodic perturbation induces abundant dynamics, the existence, the switch, and the coexistence of multiple attractors including periodic solutions with various periods, quasiperiodic solutions, chaotic (...) solutions through torus destruction, or cascade of period doublings. Throughout the results obtained, one can see that the system manifests complex dynamical behaviors such as chaos, self-organized criticality, and the transition of dynamical behaviors when it comes to periodic perturbations. Even very small variation of a parameter can result in radical changes of the dynamics, which provides a new insight into the fault dynamics. (shrink)

Peirce’s philosophy can be interpreted as an integration of mysticism and science. In Peirce’s philosophy mind is feeling on the inside and on the outside, spontaneity, chance and chaos with a tendency to take habits. Peirce’s philosophy has an emptiness beyond the three worlds of reality , which is the source from where the categories spring. He emphasizes that God cannot be conscious in the way humans are, because there is no content in his “mind.” Since there is a transcendental (...) 3 nothingness behind and before the categories, it seems that Peirce had a mystical view on reality with a transcendental Godhead. Thus Peirce seems to be a panentheist. 4 It seems fair to characterize him as a mystic whose path to enlightenment is science as a social activity. (shrink)

Many academics extol chaos theory and the science of complexity as significant scientific advances with application in such diverse fields as biology, anthropology, economics, and history. In this paper we focus our attention on structure‐within‐chaos and the dynamic self‐organization of complex systems in the context of social philosophy. Although the modern formulation of the science of complexity has developed out of late‐twentieth‐century physics and computational mathematics, its roots may extend much deeper into classical thinking. We argue here that the essential (...) ideas and predictions of the science of complexity are found within the social ordering principle of li (the rites) in Confucius's Analects. (shrink)
