In this paper, we investigate the ultimate bound set and positively invariant set of a 3D Lorenz-like chaotic system, which is different from the well-known Lorenz system, Rössler system, Chen system, Lü system, and even Lorenz system family. Furthermore, we investigate the global exponential attractive set of this system via the Lyapunov function method. The rate of the trajectories going from the exterior of the globally exponential attractive set to the interior of the globally exponential attractive set is also obtained (...) for all the positive parameters values a,b,c. The innovation of this paper is that our approach to construct the ultimate bounded and globally exponential attractivity sets assumes that the corresponding sets depend on some artificial parameters ; that is, for the fixed parameters of the system, we have a series of sets depending on λ and m. The results contain the known result as a special case for the fixed λ and m. The efficiency of the scheme is shown numerically. The theoretical results may find wide applications in chaos control and chaos synchronization. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Humans and the World: From the Perspective of Affairs by Yang GuorongHuanyou Li1 (bio)Ren yu Shijie: Yi Shi Guanzhi 人與世界：以事观之 (Humans and the World: From the Perspective of Affairs). By Yang Guorong 杨国荣. Beijing: Sanlian Press, 2021. Pp. xii+ 289. Paperback RMB55, isbn 9787108071217.Yang Guorong is not only a prominent scholar specializing in Chinese philosophy, but also a contemporary Chinese philosopher who has devoted himself to creating his (...) own philosophical system known as "concrete metaphysics" (juti xingershangxue 具体形而上学). In Humans and the World: From the Perspective of Affairs (hereafter Humans and the World), Yang delves into his philosophical system, with a primary focus on affairs (shi 事), which he sees as an embodiment of his ideas.According to Yang, "affairs" refers to actual human activities, encompassing both the act of "doing affairs" (zuoshi 作事) and its results. In essence, "affairs" or "doing affairs" represent humans' engagement in understanding and transforming the world while also striving for self-realization. "From the perspective of affairs" entails understanding humans and the world, as well as their correlation, in a primitive and fundamental manner. Yang aims to achieve the unification of "that which is antecedent to the material form" (xingershang 形而上) and "that which is subsequent to the material form" (xingerxia 形而下), which serves as the central theme and objective of his philosophical system.Humans and the World has six chapters in total. In Chapter 1, the author elucidates the intricate relationship between affairs and the actual world. From his perspective, the emergence of the actual world is rooted in the process of human activities that involve transforming things (wu 物) (p. 29). Thus, this chapter primarily delves into the distinction between things and affairs. Yang draws upon and examines various pertinent theories, including those from Confucianism, Daoism, Heidegger, and Wittgenstein. He argues that things possess their inherent and natural existence (benran cunzai 本然存在), but it is only through affairs that they can actively participate in the becoming of the actual world. Throughout the process of engaging in affairs, humans can grasp the underlying principles of things, which, in turn, continue to exist in manifold forms. Additionally, as these things serve human needs, their significance becomes manifest (pp. 30-42). Hence, doing affairs not only involves [End Page 1] understanding or recognizing things but also entails making value judgements. In the actual world, the unity of fact and value can be achieved through the medium of affairs. When humans are involved in doing affairs, things are no longer confined to their inherent nature or merely existing in themselves. Instead, they are transformed through the concrete and practical actions of humans, contributing to the construction of the actual world. It is through this dynamic interplay between things and humans that the certainty of the actual world is realized (p. 48).Chapter 2 further explores the correlation between human existence and affairs. The author asserts that affairs encompass the entire process of human existence (p. 51). Engaging in affairs involves transforming things, effecting changes in the world, accumulating empirical experiences, cultivating personal virtues, and actualizing social roles. This interplay with affairs reflects the structural manifestation of human existence in diverse forms (pp. 53-64). According to Yang, the concrete significance of human existence lies in the realization of the value of being human, which is to understand and transform the world. This necessitates that humans actively participate in creative activities, which, in essence, means they must be involved in doing affairs. From Yang's perspective, true freedom and fulfillment can only be attained when individuals immerse themselves in concrete affairs, utilizing their essential power and overcoming challenges. By doing so, they will avoid feelings of dullness or emptiness, because the fulfillment of doing affairs requires more than mere personal ability--it involves understanding objective realities and adapting to specific circumstances. Moreover, it demands a positive approach that unifies the principles of righteousness, goodness, and effectiveness. In this manner, humans can successfully navigate their engagement with affairs and realize their potential for freedom and self-fulfillment (pp. 67-69).Chapter 3 focuses on the relationship between "being" and "becoming" viewed from the perspective of affairs. Yang examines Whitehead's ideas and argues that the original world (benren shijie 本然世界) experiences change... (shrink)

Benevolent leadership is generally considered to be beneficial for work initiative. However, based on social exchange theory, this paper explores an inverted U-shaped relationship between benevolent leadership and work initiative. Using a multilevel structural equation model that analyzed the data from 596 employees and 139 supervisors in multiple technology companies, our findings show that benevolent leadership had an indirect, negative curvilinear relationship with work initiative via work engagement at both the individual and team levels. Furthermore, we also indicate that growth (...) need strength moderates the positive relationship between benevolent leadership and work engagement at the individual level. Theoretical and practical implications and future research directions are discussed. (shrink)

ObjectiveType 2 diabetes mellitus (T2DM) is a high risk of cognitive decline and dementia, but the underlying mechanisms are not yet clearly understood. This study aimed to explore the functional connectivity (FC) and topological properties among whole brain networks and correlations with impaired cognition and distinguish T2DM from healthy controls (HC) to identify potential biomarkers for cognition abnormalities.MethodsA total of 80 T2DM and 55 well-matched HC were recruited in this study. Subjects’ clinical data, neuropsychological tests and resting-state functional magnetic resonance (...) imaging data were acquired. Whole-brain network FC were mapped, the topological characteristics were analyzed using a graph-theoretic approach, the FC and topological characteristics of the network were compared between T2DM and HC using a general linear model, and correlations between networks and clinical and cognitive characteristics were identified. The support vector machine (SVM) model was used to identify differences between T2DM and HC.ResultsIn patients with T2DM, FC was higher in two core regions [precuneus/posterior cingulated cortex (PCC)_1 and later prefrontal cortex_1] in the default mode network and lower in bilateral superior parietal lobes (within dorsal attention network), and decreased between the right medial frontal cortex and left auditory cortex. The FC of the right frontal medial-left auditory cortex was positively correlated with the Montreal Cognitive Assessment scales and negatively correlated with the blood glucose levels. Long-range connectivity between bilateral auditory cortex was missing in the T2DM. The nodal degree centrality and efficiency of PCC were higher in T2DM than in HC (P < 0.005). The nodal degree centrality in the PCC in the SVM model was 97.56% accurate in distinguishing T2DM patients from HC, demonstrating the reliability of the prediction model.ConclusionFunctional abnormalities in the auditory cortex in T2DM may be related to cognitive impairment, such as memory and attention, and nodal degree centrality in the PCC might serve as a potential neuroimaging biomarker to predict and identify T2DM.
