Two experiments were conducted to examine adult learners' ability to extract multiple statistics in simultaneously presented visual and auditory input. Experiment 1 used a cross-situational learning paradigm to test whether English speakers were able to use co-occurrences to learn word-to-object mappings and concurrently form object categories based on the commonalities across training stimuli. Experiment 2 replicated the first experiment and further examined whether speakers of Mandarin, a language in which final syllables of object names are more predictive of category membership (...) than English, were able to learn words and form object categories when trained with the same type of structures. The results indicate that both groups of learners successfully extracted multiple levels of co-occurrence and used them to learn words and object categories simultaneously. However, marked individual differences in performance were also found, suggesting possible interference and competition in processing the two concurrent streams of regularities. (shrink)
Evidence suggests divergent thinking is the cognitive basis of creative thoughts. Neuroimaging literature using resting-state functional connectivity has revealed network reorganizations during divergent thinking. Recent studies have revealed the changes of network organizations when performing creativity tasks, but such brain reconfigurations may be prolonged after task and be modulated by the trait of creativity. To investigate the dynamic reconfiguration, 40 young participants were recruited to perform consecutive Alternative Uses Tasks for divergent thinking and two resting-state scans were used for mapping (...) the brain reorganizations after AUT. We split participants into high- and low-creative groups based on creative achievement questionnaire and targeted on reconfigurations of the two brain networks: default-mode network and the network seeded at the left inferior frontal gyrus because the between-group difference of AUT-induced brain activation located at the left IFG. The changes of post-AUT RSFCs indicated the prolonged effect of divergent thinking. More specifically, the alterations of RSFCIFG−AG and RSFCIFG−IPL in the high-creative group had positive relationship with their AUT performances, but not found in the low-creative group. Furthermore, the RSFC changes of DMN did not present significant relationships with AUT performances. The findings not only confirmed the possibility of brain dynamic reconfiguration following divergent thinking, but also suggested the distinct IFGN reconfiguration between individuals with different creativity levels.

War, this social phenomenon that comes into being as an accompaniment to the private ownership system and that served as the primary form of struggle during the transition from slavery to feudalism, existed over the entire course of the Spring and Autumn and Warring States periods. And during the more than two hundred years of the Warring States period, the situation was even more striking, the struggles being especially sharp. New-style iron armaments and other such weapons were invented and employed (...) in large numbers. The scale of war developed from engagements during the Spring and Autumn period where ten thousand troops might be used to battles involving several hundreds of thousands of troops. It was precisely during this development of warfare that China's newly emerging landlord class united China in 221 B. G. and completed the transition from slavery to feudalism. During the long wars between the newly emerging landlord class and the decadent slave-owning class of the Spring and Autumn and Warring States periods, Legalist military thought took shape, and it was an important element in securing revolutionary victory for the newly emerging landlord class.

In response to numerous recent cases involving materially misstated financial information arising from fraudulent financial reporting, companies, auditors, and academics have increased their focus on strengthening internal controls as a means of deterring such unethical behaviors. However, prior research suggests that stronger controls may actually exacerbate the very opportunistic behavior the controls are intended to curb. The current study investigates whether the efficacy of an implemented control is conditioned on not only the strength of the control, but also on how (...) the firm frames the purpose for implementing the control. A monitoring purpose frames controls as reducing managers’ opportunities to engage in self-interested behavior, while a coordinating purpose frames controls as facilitating coordination between the firm and its managers. We posit that the efficacy of stronger controls to reduce unethical fraudulent reporting depends on the control frame. Using an experiment, this study investigates the interactive effect of control strength and control frame on managers’ fraudulent reporting decisions. As predicted, our results show that when controls are framed for monitoring purposes, stronger controls result in less fraudulent reporting than weaker controls. Conversely, when controls are framed for coordinating purposes, stronger controls result in more fraudulent reporting than weaker controls. Our results suggest that an inconsistency between the firm’s choice of the control strength and the control frame reduces the efficacy of the implemented control to curb unethical reporting behaviors. Furthermore, supplemental analysis shows that managers’ rationalization helps explain the interactive effect of control strength and communicated control purpose on fraudulent reporting. (shrink)
Regulators have recently relaxed some provisions of the Global Research Analyst Settlement of 2003 and associated reforms, which arose from charges that conflicts of interest within investment banks had induced the issuance of fraudulent or otherwise misleading analyst research reports. We examine the effectiveness of the Global Settlement in reducing the systematic optimism observed in stock recommendations of analysts whose employer is a merger and acquisition advisor for the covered firm, by comparing the optimism exhibited in stock recommendations issued by (...) these analysts and by unaffiliated analysts before and after the Global Settlement. To control for the impact on analyst optimism of other time varying factors, our sample includes cases from the US and from other countries in which the Global Settlement had no direct impact. We argue that if the Global Settlement was effective, there should be a reduction in the relative optimism of affiliated analysts following this reform, and that reduction in the relative optimism should be greater for affiliated US analysts, than for affiliated analysts from non-US countries. When optimism is measured over a 180-day period surrounding the M&A announcement, we find a significantly greater reduction in US affiliated analysts’ optimism than occurs outside the US. However, evidence regarding analysts’ optimism in the 90-day period prior to the announcement of an M&A deal is mixed. (shrink)
The Sea as Mirror traces the pressing and repressed material and symbolic presence of the Mediterranean Sea and the Atlantic Ocean from Plato to Heidegger. To do so, Wu Yi employs the maritime as a lens to understand the drive of philosophy as both a response to and moment within the impetus of Western colonization. Yi examines how philosophy has again and again constructed itself as a genre in opposition to the movement of deterritorialization and fluidity of mimesis. She does (...) so via the method (meta, “after” + hodos, “way, journey”) of a series of essayings (in the original sense of trial, measure, attempt) across a geopolitical topography of discourses. These include philosophical texts drawn from a constellation of historical topoi at the critical moments of their encounter with the maritime: Plato and Euripedes’s work from fifth-century Athens; Augustus and Plautus’s writings from republican and early imperial Rome; Shakespeare’s creations from Elizabethan England; Kant and Rousseau’s texts from enlightenment continental Europe; and the thinking of Husserl and Heidegger from interwar Germany of the twentieth century. For each historical topos, Yi juxtaposes different representations of and responses to the maritime through the reading of a philosophical text vis-à-vis the reading of a literary text. In so doing, she lays bare the deep political and moral ambiguity attributed to the ocean in Western philosophical and literary imaginaries. (shrink)
Ample manpower and material were mobilized for research on Liuhsia Chih in 1974. A thorough investigation of the life of a very famous leader of the working people's uprising and a clarification of erroneous historical legends about him are important for studies of history. Undoubtedly, a correct understanding of this historical character's features and propaganda about his revolutionary deeds will be conducive to the cause of socialism in our country. It is regrettable that some widely publicized works in 1974 (...) were rather inferior in quality and had unfavorable effects because their authors accepted the guidance of erroneous political thought and because the academic atmosphere was somewhat foul. As a result, people became confused. All this was caused by the control, interference and destruction of the "gang of four.". (shrink)
Aiming at the problem of insufficient health monitoring of the elderly in the existing home care system, this paper designs a health information analysis and early warning system based on the Internet of Things technology, which can monitor the physiological data of the elderly in real time. It also can be based on the elderly real-time monitoring data, physical examination data, and other types of health data, which can be used to predict diseases, so as to achieve “early detection and (...) early treatment” of diseases. First, analyse and design the architecture and content of the home care monitoring system based on the Internet of Things. Secondly, based on the collected heart rate, blood pressure, and three-axis acceleration information of the elderly, it is analysed to determine whether the elderly are in danger of falling, and the designed system is used for early warning. Finally, this paper analyses the prediction algorithm theory of the disease prediction module in the health monitoring software of the home care system. In order to improve the accuracy of prediction, the DS evidence theory is used to optimize the traditional BP neural network algorithm and conduct experimental tests. The test results show that the health information analysis and early warning software of the home care system meet actual needs and achieve the expected goals. (shrink)
BackgroundMedical disputes, medical disturbances, verbal and physical violence against physicians, and burnout have reached epidemic levels. They may negatively impact both physicians and the healthcare system. The experience of medical disputes, medical disturbances, verbal, and physical violence, and burnout and the correlates in physicians working in public hospitals in China needed to be investigated.MethodsA nationwide cross-sectional survey study was conducted between 18 and 31 March 2019. An anonymous online questionnaire was administered. The questionnaire included the 22-item Maslach Burnout Inventory-Human Services (...) Survey. We also collected data on demographic and job-related factors, as well as physicians’ experiences of medical disputes, medical disturbances, verbal and physical violence from patients and the patients’ family members.FindingsIn total, 22,213 physicians from 144 tertiary public hospitals in all of China’s 31 provinces completed the survey. The overall burnout rate among the surveyed physicians was 31.28%. Moreover, 33.48% of physicians experienced disputes, 20.86% experienced disturbances, 48.52% experienced verbal violence, and 5.84% experienced physical violence in the past 12 months. Factors found to be significantly associated with burnout included younger age, being divorced or widowed, having a lower educational background, working in internal medicine departments, longer working hours per day, working in general hospitals, being in East China, as well as having experienced disputes, disturbances, and physical and verbal violence.InterpretationClose to a third of the Chinese doctors working in the tertiary hospitals reportedly experienced burnout, and the problem is related to the unsafe working environment caused by the worsening doctor-patient relationship.

Comparing estimates of the cost-effectiveness of human immunodeficiency virus (HIV) interventions can help communities select an HIV prevention portfolio to meet local needs efficiently. The authors developed a spreadsheet tool to estimate the relative cost-effectiveness of 26 HIV prevention interventions. HIV prevalence of the population at risk and the cost per person reached were the two most important factors determining cost-effectiveness. In low-prevalence populations, the most cost-effective interventions had a low per-person cost. Among the most cost-effective interventions overall were showing (...) videos in sexually transmitted disease clinics and raising alcohol taxes. (shrink)
Contrary to its self-proclamation, philosophy started not with wonder, but with time thrown out of joint. It started when the past has become a problem. Such was the historical situation facing Athens when Plato composed his Socratic dialogues. For the philosopher of fifth century BCE, both the immediate past and the past as the Homeric tradition handed down to the citizens had been turned into problematicity itself. In this essay, I will examine the use of philosophy as memory theatre in (...) Plato's Republic. I shall do so by interpreting Book X of the Republic as Plato's “odyssey” and suggest that such Platonic odyssey amounts to an attempt to re-inherit the collapsed spatial and temporal order of the fallen Athenian maritime empire. In my reading, the Odysseus in the Myth of Er comes forth for Plato as the exemplary Soldier-Citizen-Philosopher who must steer between the Scylla of ossified political principles and the whirling nihilism of devalued historical values, personified by Charybdis. I shall further suggest that Plato’s memory theatre also constitutes a device of amnesia and forgetting. The post-Iliadic Odysseus must drink of forgetfulness from the river Lethe, so that the revenant soldier, Er, and those who inherited the broken historical present during and after the Peloponnesian War, would be enabled to remember in a particular way. Such remembrance, I shall conclude, may be what Plato means by philosophy, a memory theatre of psychic regulation and moral economy that sets itself decidedly apart from earlier tragic and comic catharsis.

Representations of historicism as the loss of meaning in history and critiques of historicism as the critique of such a loss had been pervasive since late nineteenth century till the Second World War. Among historicism’s most powerful and representative critics were the young Nietzsche and Benjamin in his Parisian exile. This essay seeks to trace from Nietzsche to Benjamin an unbroken yet growing line of critique—of historicism as the “sickness of time” from which modernity suffers, and from which it has (...) been trying to recover. Two attempts at such a recovery will be examined and juxtaposed: The Uses and Disadvantages of History for Life and Theses on the Philosophy of History. By thus situating both historicism and its critiques within the desires and anxieties of modernity, this essay tries to delineate and to understand the peculiarly modernist shapes assumed by the historical and its discontents.

This essay investigates the rôle of the North Atlantic as a silent actant in the dramatic economy of Shakespeare’s Hamlet. It takes the series of actions of Hamlet’s deportation by sea, his nocturnal transformation on board and his surprise return with the pirate ship as the axis around which the play turns. It examines the movement of deterritorialization and mimesis in the constitution of sovereignty by the ceaseless transference of piracy and inter-imperial rivalries and passages. Interpreting Hamlet as being not (...) just a play of nothingness and nihilism, born of and residing in the interstice of disjointed historical time, this essay argues that Hamlet is a play that inherits and inhabits the cranny of fractured historical space from Elizabethan to Jacobean England when the English isle became what Carl Schmitt called the “agency of the spatial turn to a new nomos of the earth.” The old nomos of the earth, terra firma in the Greco-Roman and feudal senses, was challenged by the new freedom of the sea which demanded a separate and distinct global order. This essay poses the question whether the dramatic economy of Hamlet as split by and revolving around the physical presence and symbolic charges of the North Atlantic in fact constitutes the irrhythm and mis-punctuation of this spatial turn toward a maritime modernity.

The Copernican Revolution had meant for modern Europe surer navigation, bolder voyages and wilder discoveries. With the declaration of independence of America in 1781 and the publication of The Critique of Pure Reason by Immanuel Kant in the same year, the age of Enlightenment defined itself as an age of coming of age and of daring to know. This essay tries to draw out the peculiar enlightenment ethos of a youth against youth through Kant’s depiction of the voyage of human (...) reason in the First Critique. It will do so by examining the four-fold sense of objects, the island of truth surrounded by illusion, amphibolic insularity, the mirror of schema and the “No Further!” of the Pillars of Hercules. Interrogating the dual sense of “limit” as both infinitizing, transgressively de-territorializing and yet at the same time self-delimiting, self-critiquingly re-territorializing, this essay argues for a hermeneutic vantage point to comprehend Kant as the unwilling mariner who by way of the transcendental as-if attempted to gain a certain spectatorship, a particular possibility of seeing - at a shore already and increasingly lost to the European and global humanity of centuries to come.
