The study of cyber-attacks, and in particular the spread of attack on the power cyber-physical system, has recently attracted considerable attention. Identifying and evaluating the important nodes under the cyber-attack propagation scenario are of great significance for improving the reliability and survivability of the power system. In this paper, we improve the closeness centrality algorithm and propose a compound centrality algorithm based on adaptive coefficient to evaluate the importance of single-layer network nodes. Moreover, we quantitatively calculated the decouple degree of (...) cascading failures caused by exposed nodes formed by attack propagation. At last, experiments based on the IEEE 57 test system show that the proposed compound centrality algorithm can match the cyber-attack propagation scenario well, and we give the importance values of the nodes in a specific attack scenario.

BackgroundThe COVID-19 pandemic has changed the healthcare landscape drastically. Stricken by sharp surges in morbidity and mortality with resource and manpower shortages confounding their efforts, the medical community has witnessed high rates of burnout and post-traumatic stress amongst themselves. Whilst the prevailing literature has offered glimpses into their professional war, no review thus far has collated the deeply personal reflections of physicians and ascertained how their self-concept, self-esteem and perceived self-worth has altered during this crisis. Without adequate intervention, this may (...) have profound effects on their mental and physical health, personal relationships and professional efficacy.MethodsWith mentions of the coronavirus pervading social media by the millions, this paper set out to collate and thematically analyse social media posts containing first-person physician reflections on how COVID-19 affected their lives and their coping mechanisms. A consistent search strategy was employed and a PRISMA flowchart was used to map out the inclusion/exclusion criteria.ResultsA total of 590 social media posts were screened, 511 evaluated, and 108 included for analysis. Salient themes identified include Disruptions to Personal Psycho-Emotional State, Disruptions to Professional Care Delivery, Concern for Family, Response from Institution, Response from Society and Coping Mechanisms.ConclusionIt is evident that the distress experienced by physicians during this time has been manifold, multi-faceted and dominantly negative. Self-concepts were distorted with weakened self-esteem and perceived self-worth observed. The Ring Theory of Personhood (RToP) was adopted to explain COVID-19’s impact on physician personhood as it considers existential, individual, relational and social concepts of the self. These entwined self-concepts serve as ‘compensatory’ to one another, with coping mechanisms buffering and fortifying the physician’s overall personhood. With healthcare institutions playing a vital role in providing timely and targeted support, it was further proposed that a comprehensive assessment tool based on the RToP could be developed to detect at-risk physicians and evaluate the presence and effectiveness of established support structures.

Through empirical studies or laboratory tests, previous studies have shown that sport-confidence, attention, and emotion regulation are key factors in archery performance. The present study aims to further identify the effects and pathways of sport-confidence, attention, and cognitive reappraisal on real-world archery performance by constructing a hypothesized model to provide a basis for scientific training of athletes to improve sport performance. A survey design was utilized on a sample of 61 athletes from the Chinese National Archery Team to test the (...) model. The measurement and hypothesized models were tested using partial least squares structural equation modeling. The results indicate that the model fit well and explained 33.6% of the variance in archery performance. Sport-confidence and attention were important predictive indicators of archery performance, while the relationship between cognitive reappraisal and archery performance showed considerable complexity. We conclude that the development of sport-confidence and attention of archery athletes should be strengthened, but athletes who use cognitive reappraisal in archery competition should be mindful of its potential appropriation of cognitive resources and should be directed to improve sport-confidence or develop a positive orientation to arouse excitement.

GraphicalPatients with early- to middle-stage PD were enrolled for C-Gait assessment and traditional walking ability assessments. The correlation of C-Gait assessment and traditional walking tests were studied. Two models were established based on C-Gait assessment and traditional walking tests to explore the value of C-Gait assessment in predicting freezing of gait.ObjectiveEfficient methods for assessing walking adaptability in individuals with Parkinson’s disease are urgently needed. Therefore, this study aimed to assess C-Gait for detecting freezing of gait in patients with early- to (...) middle-stage PD.MethodPeople with PD diagnosis were recruited from April 2019 to November 2019 in Beijing Rehabilitation Hospital. The participants performed six items of walking adaptability on an instrumented treadmill augmented with visual targets and obstacles. The patient’s walking adaptability was evaluated by C-Gait assessment and traditional walking tests, and FOG-related indexes were collected as outcome measures. Two discriminant models were established by stepwise discriminant analysis; area under the receiver operating characteristic curve was used to validate the models.ResultIn total, 53 patients were included in this study. Most C-Gait assessment items had no or low correlations with traditional walking tests. The obstacle avoidance and speed of adaptation items could lead to FOG with high sensitivity. In addition, the C-Gait assessment model had slightly better discrimination of freezers from non-freezers compared with traditional walking test models ; specifically, obstacle avoidance and speed of adaptation have uniquely discriminant potential.ConclusionC-gait assessment could provide additional value to the traditional walking tests for PD. Gait adaptability assessment, as measured by C-Gait, may be able to help identify freezers in a PD population. (shrink)

ArgumentRecent studies in Sinology have shown that Qing dynasty editors acted as philologists. This paper argues that the identification of their philological methods and editorial choices suggests that their choices were not totally neutral and may have significantly shaped the way modern historians interpreted specific works edited by mathematicians of that dynasty. A case study of the re-edition in 1798 of a Song dynasty treatise, theYigu yanduan(1259), by a Qing dynasty mathematician will illustrate this point. At the end of the (...) eighteenth century, Li Rui (1773–1817) was asked to prepare an edition of the mathematical works written by Li Ye (1192–1279) for a private collection. Li Rui was a talented mathematician, but he was also a meticulous editor and trained philologist. He adopted his editorial model from the preparation of the imperial encyclopaedia, theSiku quanshu, but Li Rui also made some corrections to the text in an effort to restore an older version of Li Ye's treatises that had been lost. Convinced of the Chinese origin of algebra, Li Rui used philological techniques to recover the lost materials and to restore the roots of “Chinese mathematics.” TheYigu yanduancontains two algebraic procedures to set up quadratic equations, one from the procedure ofCelestial Source(tian yuan shu) and the other from theSection of Pieces[of Areas] (tiao duan). Curiously, the second procedure has not yet attracted the attention of scholars so far, although Li Rui's edition is the one typically used by twentieth-century historians of mathematics. Today, theCelestial Sourcecharacterizes “Chinese algebra.” However, the specific concerns of Li Rui about the procedure ofCelestial Source, combined with his editorial methods, contributed to this perspective.

We provide new findings that add to the growing body of empirical evidence that important epistemic intuitions converge across cultures. Specifically, we selected three recent studies conducted in the US that reported surprising effects of knowledge attribution among English speakers. We translated the vignettes used in those studies into Mandarin Chinese and Korean and then ran the studies with participants in Mainland China, Taiwan, and South Korea. We found that, strikingly, all three of the effects first obtained in the US (...) also emerged in the East Asian cultures we studied. Our findings not only cohere with but also provide—at least moderate—support for the existence of extensive convergences of important epistemic intuitions across cultures. (shrink)

Business Ethics: A European Review, EarlyView.

In Portugal, as elsewhere, the rhetoric of managerialism in higher education is becoming firmly entrenched in the governmental policymakers’ discourse and has been widely disseminated across the institutional landscape. Managerialism is an important ideological support of New Public Management policies and can be classified as a narrative of strategic change. In this paper, we analyse how far the managerialism narrative has been injected into the discursive repertory of Portuguese academics in their role as the co-ordinators of the higher education institutions’ (...) teaching and academic middle levels. Based on an analysis of interview responses, it seems that most academics support traditional academic values such as autonomy and collegiality, and reject university or polytechnic governance based on corporate philosophy.

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question remains controversial (...) in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

For many energy companies in China, green brand strategy is becoming an important approach to enhance competitive advantage. However, greenwashing behaviors result in a crisis of trust. Existing research focuses on green marketing, but is silent on the institutional view of the trust crisis resulting from greenwashing by energy brands. Thus, this study takes a decoupling perspective from institutional theory and considers legitimacy, energy policy management, and green brand theories to shed light on the path from the decoupling of an (...) energy brand from green promise to green energy brand trust and the role of brand legitimacy and brand loyalty. It then analyzes survey data to conclude that DEBG not only has a direct negative effect on GEBT but also has an indirect influence through the vital mediating role of green energy brand legitimacy. Moreover, brand loyalty is a moderating factor and can alleviate the energy brand trust crisis. These findings not only can enrich the theories of energy brand management and green marketing but also offer important implications for energy policy management. (shrink)

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic (...) numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing. (shrink)

This article is a Gadamer-Perelman's debate. The author points out the limits of the gadamerian's hermeneutic conception of philosophy and criticizes this conception from Perelman's new rhetoric point of view. Instead of speaking of truth as an ontological originary experience, the rhetorical foundation of philosophy allows us to say that in philosophy the important is the contrastation and the confrontation of criteria and that, for that reason, philosophy is above all characterized by discussibility.

The development of living organisms requires a precise coordination of all basic cellular processes, in space and time. Early embryogenesis of most species with externally deposited eggs starts with a series of extremely fast cleavage cycles. These divisions have a strong influence on gene expression as mitosis represses transcription and pre‐mRNA processing. In this review, we will describe the distinct adaptations for efficient gene expression and discuss the emerging role of the multifunctional NineTeen Complex (NTC) in gene expression and genomic (...) stability during fast proliferation.

Search is a prerequisite for successful performance in a broad range of tasks ranging from making decisions between consumer goods to memory retrieval. How does aging impact search processes in such disparate situations? Aging is associated with structural and neuromodulatory brain changes that underlie cognitive control processes, which in turn have been proposed as a domain‐general mechanism controlling search in external environments as well as memory. We review the aging literature to evaluate the cognitive control hypothesis that suggests that age‐related (...) change in cognitive control underlies age differences in both external and internal search. We also consider the limits of the cognitive control hypothesis and propose additional mechanisms such as changes in strategy use and affect that may be necessary to understand how aging affects search.

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.

PurposeThe study aimed at investigating the state of psychiatric nurses’ job satisfaction, job burnout, and the moderating effect of family support between them in China during the COVID-19 pandemic.Materials and methodsOnline self-report questionnaires were distributed and 212 psychiatric nurses participated in the research. Pearson correlation analysis, multiple stepwise regression analysis, and simple slope test were used for data analysis.ResultsThe results showed that the status of their job satisfaction and burnout did not reach a satisfactory level and job satisfaction had a (...) significant negative impact on job burnout. Meanwhile, family support played a negative moderating role between the two variables.ConclusionPsychiatric nurses suffered from job burnout in China during the COVID-19. Family support could have a counterproductive effect when the nurses were experiencing decreasing job satisfaction. It gave suggestions to the medical institutions and the government to improve the psychological well-being of the psychiatric nurses and even of all the medical staff. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 1-17 [Access article in PDF] What if the Father Commits a Crime? Rui Zhu Apparently, Socrates and Confucius respond similarly to the question if a son should turn in his father in the case of the father's misdemeanor. When Euthyphro, flaring his pride of his moral impartiality, tells Socrates that he is on his way to report his father because he (...) has thrown one of the household slaves into a ditch and left him bound there until he was dead, Socrates says, "Good Heaven! Certainly, Euthyphro, most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom." 1According to Socrates, only a man of high wisdom knows how to prosecute his father righteously, but Euthyphro does not appear to have this wisdom. When his interlocutor observes that an upright man in his state would bear witness against his father if he misappropriates a sheep, Confucius contradicts the interlocutor's understanding of uprightness by speaking in a matter-of-fact tone: "In my country the upright men are of quite another sort. A father will cover up for his son, and a son his father—which incidentally does involve a sort of up—rightness." 2Confucius stands on the same line with Socrates but seems the more radical of the two. Socrates does not directly refute Euthyphro and only suggests that he make sure he understands what he is doing before going any further. Socrates is not only typically Socratic—indirect and suggestive—but also sounds so reasonable that Euthyphro appears in contrast to be a reckless youth who harbors [End Page 1] only a faint understanding of morality. Confucius's response is more rigid, for he categorically dismisses an act of the Euthyphroian kind. He demands that father and son cover up for each other in the case of either one's guilt. Compared to Socrates, Confucius advocates the position that seems a little too strong and leaves no room for justice, while Socrates does not have that problem with justice. This is how we feel about Socrates and Confucius on our first impression. The prima facie observations that we make from the remarks of Socrates and Confucius seem both plain and unproblematic.By embedding these remarks into their respective social or philosophical cultures, this paper will show that our previous observations are not quite accurate. The apparent affinity of the Socratic and Confucian stances belies different underlying moral philosophies. We want to use their comments as bridges to explore the early Greek and Confucian ethics and show how different a picture we see after things are examined within their traditions.The issue of a possible father-son conflict may be treated as a case study of the early Greek (the Heroic era until the age of Socrates) and early Confucian (Confucius and Mencius) morals. There is a strong theme in the early Greek morals that allows, or sometimes demands, a son such as Euthyphro to prosecute his father for the sake of justice, because justice, instead of love (philein) or filial piety, is the governing principle in the early Greek ethics. Confucian ethics is founded on love (human-heartedness), which in turn is extended from the love between father and son. All moral principles including justice are derived from this extension of love. The mutual love of father and son then becomes the governing principle in the case of Confucianism. A Guilty Father: The Greek Motif The question, "What if the father commits a crime?" has a certain realistic aroma to a boy coming of age in the Hesiodic Greek world. That father has to be overcome by son before some relief from strife becomes possible is a familiar theme in Greek literature. In Hesiod's Theogony, Uranus (the sky) incurs hatred from all his newborn children since he hides them in their mother Gaia's womb and does not let them return to the light, for no reason...

Most mass incidents are created by economic or social concerns brought on by fast socioeconomic change and poor local government. The number of mass occurrences in China has significantly increased in recent years, putting the country’s steady growth and public behavior decision-making in harm. We examine the factors that influence public behavior decision-making in the following significant factors, contributing to the development of effective prevention and response strategies. The structural equation approach is used to analyze the main determinants influencing public (...) behavioral decisions in the aftermath of mass incidents using surveys of a large population. The finding shows that media plays a mediating role in the relationship between mass occurrences and influencing factors impacting public emotion. The direct and indirect effects of public behavior decision-making and its role increasingly social changes as things happen, government credibility, media plays mediating role in public emotional factors. All directly impact public behavior decision-making, while emotional factors have an indirect impact via media intermediaries. The escalation of public behavior decisions is seen as a result of structural transmission and the increase of dynamic as well as other factors. (shrink)

This article engages with the historiography of the Portuguese empire with reference to Mozambique. It explores the impact of visual archives on existing debates and asks what difference photographs make to our interpretation and understanding of this colonial past. Deprived of their 'historical rights' by the requirements of the Berlin treaties that insisted on 'effective occupation', the Portuguese started to employ a complex of knowledge-producing activities in which photography was crucially involved. This article examines different photographic moments before and during (...) the 'Pacification Campaign' that assured Portugal's authority over the Gaza Empire in southern Mozambique in the 1890s, by official, commercial and missionary photographers. It identifies controversies over the small number of portraits of the Gaza king Ngungunyane that took on distinctive and disputed 'other lives' after their initial production. The realisation of how one image might be disassembled to generate others becomes an exercise - in visual terms - of rethinking colonial violence. A critical engagement with the slippages and repositionings around photographs, and the errors or disputes in various captions, allows for a better understanding of the production of both silence and particular narratives in the archives and popular history. The demonstration of these other lives matters because it stimulates awareness of what is seen, what is made visible, and addresses the desire to look beyond the image to find others in a continuous interrogation of photographic excess.

Based on a sample of 46 Portuguese schoolbooks, this study aims to understand how factory-farmed animals are presented in such books across the themes of food and health, the environment and sustainability, and animal welfare. It examines whether schoolbooks address the importance of reducing the consumption of animal-based products for a healthy diet, whether plant-based diets are recognized as healthy, whether animal welfare and agency are considered, and whether the livestock sector is indicated as a major factor in environmental degradation. (...) The findings show that schoolbooks present animals as essential for economic activities and human nutrition. Recommendations on reducing the consumption of animal-based products in consideration of the environment, sustainability and human health are very rare. Animal production is presented as benign, and the agency and welfare of factory-farmed animals are simply not addressed. (shrink)

Evolutionary psychologists should go beyond research on individual differences in attitudes and focus more on detailed models of psychological mechanisms. We argue for complementing attitude research with agent-based computational modeling of mate choice. Agent-based models require detailed specification of individual choice mechanisms that can be evaluated in terms of both their psychological plausibility and the population-level outcomes they produce.
