Adaptive dynamic programming, which belongs to the field of computational intelligence, is a powerful tool to address optimal control problems. To overcome the bottleneck of solving Hamilton–Jacobi–Bellman equations, several state-of-the-art ADP approaches are reviewed in this paper. First, two model-based offline iterative ADP methods including policy iteration and value iteration are given, and their respective advantages and shortcomings are discussed in detail. Second, the multistep heuristic dynamic programming method is introduced, which avoids the requirement of initial admissible control and achieves (...) fast convergence. This method successfully utilizes the advantages of PI and VI and overcomes their drawbacks at the same time. Finally, the discrete-time optimal control strategy is tested on a power system.

Patients with chronic obstructive pulmonary disease are characterized by attenuated pulmonary function and are frequently reported with cognitive impairments, especially memory impairments. The mechanism underlying the memory impairments still remains unclear. We applied resting-state functional magnetic resonance imaging to compare the brain local activities with static and dynamic amplitude of low-frequency fluctuations among patients with COPD and healthy controls. Compared with HC, COPD patients exhibited decreased sALFF in the right basal ganglia and increased dALFF in the bilateral parahippocampal/hippocampal gyrus. The (...) reduced the left basal ganglia was associated with lower oxygen partial pressure. Besides, the increased dALFF in the left hippocampal/parahippocampal cortex was associated with poor semantic-memory performance and the increased dALFF in the left hippocampal/parahippocampal cortex was associated the forced vital capacity. The present study revealed the abnormal static and dynamic local-neural activities in the basal ganglia and parahippocampal/hippocampal cortex in COPD patient and its relationship with poor lung function and semantic-memory impairments.

Telepresence in e-commerce, the feeling of resembling shopping in a physical store, plays a critical role in determining online purchase intention. However, the cognitive mechanism and boundary conditions about its effect still need further investigation. The current study construed flow experience and socioeconomic status as important variables and developed a moderated mediation model for their roles in the effect of telepresence. The model was supported by our study where a group of Chinese female college students participated in simulated online apparel (...) shopping and completes relevant questionnaire surveys. The results show that: website telepresence predicts positively the purchase intention of females, flow experience mediates the impact of website telepresence on purchase intention, and the relationship between website telepresence and flow experience could be moderated by socioeconomic status, namely, females with higher socioeconomic status demonstrate stronger mediation of flow experience. These findings can help researchers and online retailers understand the flow concept in e-commerce and formulate marketing strategies to retain consumers with different socioeconomic statuses.

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

It is not quite as easy to see that there is in fact no formula of this modal language having the same truth conditions (in terms of S5 Kripke semantics) as (1). This was rst conjectured by Allen Hazen2 and later proved by Harold Hodes3. We present a simple direct proof of this result and discuss some consequences for the logical analysis of ordinary modal discourse.

Objectives Older adults are considered one of the most vulnerable groups to COVID-19. However, previous studies on emotion and aging have found that older adults report better well-being than younger adults in global survey and daily report. To better understand older adults’ well-being during the COVID-19 outbreak, we examined age differences in daily affective experiences in this study. Method Two hundred and thirty-one participants from mainland China aged 18 to 85 were recruited to participate in the 14-day daily diary study, (...) after a pretest. Their trait affect and demographic information were measured in the pretest. Their daily affect and stress levels were measured in the daily assessments. Results We found that older adults reported lower perceived stress related to COVID-19 in daily life, compared to younger adults. The negative relationship between daily perceived stress and high arousal positive affect and the positive relationship between daily perceived stress and high arousal negative affect was weaker in older than younger adults. Discussion These results provide initial evidence of daily affective well-being across different age groups in adulthood during the COVID-19 outbreak. Such information is important for developing interventions to promote better well-being during the COVID-19 outbreak. (shrink)

I thought the paper by Kai-yee Wong and Chris Fraser was fascinating and insightful. Two things I especially appreciated are the clarity with which they summarize my views. I think they are quite fair and accurate. Second, I appreciate their suggestion that the way to deal with the practical problem of weakness of will has much to do with the role of the Background in shaping our actions. I think they are especially on the right track when they say that (...) the improvement of Background skills may actually narrow the range of real options for action, (p. 21) nonetheless, they do not decrease freedom. As they say, “It is a process of strengthening the self, and the agent is likely to experience the concomitant restriction of ‘live’ options not as a limitation but as strength of character.” (p. 21). That seems to me very much on the right track. What they are suggesting, and it is a powerful addition to my own writings, is that we should not just think of the Background as facilitating languages, games and social practices generally, but for morality as well (p. 23).

Several important physical implications left out in The Five Dimension Space-Time Universe: A creation and grand unified field theory model. Book, are presented under rigorous mathematical theorems. It was found that Temperature, a classical variable, must be added as an imaginary component to time, under the Quantum uncertainty dt∙dE = h/2π, so that the Gell-Mann Quark model can be verified, with gauge invariance, to form hadrons at the Bethe Fusion Temperature. Accordingly from the corresponding uncertainty dp∙dr = h/2π. Pairs of (...) Diagonal Long Range Ordered gravitons, with continuous frequency spectrum together with those represented by magnetic monopoles must be formed within the space r, of the homogenous 5D manifold, without the presents of photons, thus defines the 5D as a Black Hole. Then from which we can derive the classical Newtonian Law of attractive Gravity, as the 5D manifold is mapped by Perelmann Ricci-flow entropy mapping and the DLRO graviton pair symmetry is broken and converted into two masses, with motions satisfying Special Relativity in the doughnut shape Lorentz manifold, thus indirectly verifies the principle of Covariant Riemannian curvatures and General Relativity theory.

The sense of agency is a basic feature of our subjective experience. Experimental studies usually focus on either its attributional aspects or on its motoric aspects. Here, we combine both aspects and focus on the subjective experience of the time between action and effect. Previous studies [Haggard, P., Aschersleben, G., Gehrke, J., & Prinz, W.. Action, binding and awareness. In W. Prinz, & B. Hommel, Common mechanisms in perception and action: Attention and performance. Oxford: Oxford University Press] have shown a (...) temporal attraction in the perceived times of actions and effects, but did directly not study the relation between them. In three experiments, time estimates of an interval between an action and its subsequent sensory effect were obtained. The actions were either voluntary key press actions performed by the participant or kinematically identical movements applied passively to the finger. The effects were either auditory or visual events or a passive movement induced to another finger. The results first indicated a shortening of the interval between one’s own voluntary action and a subsequent effect, relative to passive movement conditions. Second, intervals initiated by observed movements, either of another person or of an inanimate object, were always perceived like those involving passive movements of one’s own body, and never like those involving active movements. Third, this binding effect was comparable for auditory, somatic and visual effects of action. Our results provide the first direct evidence that agency involves a generalisable relation between actions and their consequences, and is triggered by efferent motor commands. (shrink)

This book, first published in 2002, is a systematic critical overview of German aesthetics from 1750 to the present. It begins with the work of Baumgarten and covers all the major writers on German aesthetics that follow, including Kant, Schiller, Schelling, Hegel, Nietzsche, Heidegger, Gadamer and Adorno. The book offers a clear and non-technical exposition of ideas, placing these in a wider philosophical context where necessary. Such is the importance of German aesthetics that the market for this book will extend (...) far beyond the domain of philosophy to such fields as literary studies, fine art and music. (shrink)

Many find the prospect of death distressing at least partly because they believe that death deprives its subject of life’s benefits. Properly qualified, the belief is surely true. But should its truth lead us to conclude that there is something dreadful or awful about death, something that merits distress?

Drawing on insights of thinkers in the natural rights tradition, Draper analyzes numerous hypothetical cases including those involving a runaway trolley, then seeks to determine if killing civilians in war is ever justified. In his consideration of this issue he avoids appealing to the principle of double effect. Having considered hypothetical cases at length, he leaves it to others to decide if any option to go to war is justifiable. In this regard he himself is sceptical.
