ObjectiveTo investigate the instant impact of hemodialysis on the cerebral morphological measurements of patients with end-stage renal disease.Materials and methodsTwenty-five patients undergoing maintenance HD and twenty-eight age-, sex-, and education-matched healthy control were included. The HD group and HC group had 3D high-resolution structural magnetic resonance imaging scans twice and once, respectively. Both groups underwent neuropsychologic tests. The morphological measurements of structural MRI were measured using CAT12 and these measures were compared among three groups. The relationship between morphological measures and (...) clinical parameters and neuropsychological tests were investigated through multiple regression analysis.ResultsCompared to the HC group, the cortical thickness before HD significantly decreased in the bilateral temporal lobe and significantly decreased in the left superior temporal gyrus after HD. The cortical thickness significantly increased in the bilateral temporal lobe, frontal lobe and occipital lobe after HD compared to before HD. The sulcus depth in the bilateral insula, frontal lobe, and parietal lobe after HD significantly increased compared to before HD. No significant differences in sulcus depth between HD and HC were detected. After HD, the cortical thickness of the right parsopercularis was positively correlated with the number connection test-A. Cortical thickness in multiple regions were positively correlated with blood flow velocity and cortical thickness in the left parahippocampal gyrus was negatively correlated with ultrafiltration volume. Patients showed better performance in the digit symbol test and line tracing test after HD compared to before HD, but there were no significant differences in the comparison of neuropsychologic tests between patients and HC.ConclusionThe instant morphological changes were captured during a single hemodialysis in HD patients. There was an association between these instant changes in the brain and clinical parameters and neuropsychologic tests. This work implied the instant impact of a single hemodialysis impact on the brain in HD patients. (shrink)

An amplitude controllable hyperjerk system is constructed for chaos producing by introducing a nonlinear factor of memristor. In this case, the amplitude control is realized from a single coefficient in the memristor. The hyperjerk system has a line of equilibria and also shows extreme multistability indicated by the initial value-associated bifurcation diagram. FPGA-based circuit realization is also given for physical verification. Finally, the proposed memristive hyperjerk system is successfully predicted with artificial neural networks for AI based engineering applications.

I argue that, contrary to some critics, the notion of conscious experience is a good candidate for denoting a distinct and scientifically interesting phenomenon in the brain. I base this claim mainly on an analysis of neuropsychological data concerning deficits resulting from various types of brain damage as well as some additional supporting empirical evidence. These data strongly point to the hypothesis that conscious experience expresses information that is available for global, integrated, and flexible behavior.

Few studies have actually explored the impact of the COVID-19 pandemic on mental health in college students, although many studies have suggested that the COVID-19 pandemic poses a great threat to people’s mental health in many cohorts. Furthermore, college students may be a particularly vulnerable cohort that needs more attention and access to psychological services due to the psychological changes involved in the transition to college and the characteristics of college students’ study habits and lifestyle. Therefore, investigating the basic characteristics (...) of the impact of the COVID-19 pandemic on college freshmen is of great practical importance and has theoretical implications for the identification and provisioning of services to vulnerable cohorts. A total of 5,818 college freshmen completed the College Student Adaptability Inventory. The results suggest that the mean detection rate of the seven dimensions of undergraduate maladjustment to university is 27.13%. Specifically, livelihood self-management adaptability has the highest detection rate, while environmental general evaluation has the lowest detection rate. Moreover, the school adaptation of college freshmen is impacted by gender, number of siblings, and family socioeconomic status. Specifically, students who are female, an only child, and have a lower SES have lower levels of school adaptation. However, the school adaptation of college freshmen is not influenced by minority status or left-behind status. The findings of the present study suggest that the maladaptation of college freshmen has been a common phenomenon in China during the COVID-19 epidemic. Prevention programs may be most helpful if they pay more attention to effective intervention efforts for students who are female, an only child, and have a lower SES. (shrink)

This article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity, and whether industry competition level moderates this relationship. Using data on Chinese firms’ philanthropic response to the 2008 Sichuan earthquake, we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving. The results also indicate that this positive advertising intensity-philanthropic giving relationship is stronger in competitive industries, and firms in (...) competitive industries are more likely to donate. This study thus provides evidence suggesting that even in the wake of catastrophic events, corporate philanthropic giving is strategic. (shrink)

With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...) the understanding of facial expressions of emotions. Prices of sticking with the modal view, and advantages of an expanded view, are succinctly reviewed. (shrink)

This article examines whether the charitable giving amount and likelihood of firm response to catastrophic events relate to firms’ ownership type using a unique dataset of listed firms in China, where state ownership is still prevalent. Based on the data of Chinese firms’ response to the 2008 Sichuan earthquake, we find that the extent of corporate contributions for state-owned firms following this disaster is less than that for private firms. State-owned firms are also less likely to respond in␣this disaster compared (...) to private firms. The results also␣reveal that firm size, profitability, geography, cash resource available, and leverage affect firms’ philanthropic disaster response behavior in China. (shrink)

This paper presents an extended version of the Quantified Argument Calculus (Quarc). Quarc is a logic comparable to the first-order predicate calculus. It employs several nonstandard syntactic and semantic devices, which bring it closer to natural language in several respects. Most notably, quantifiers in this logic are attached to one-place predicates; the resulting quantified constructions are then allowed to occupy the argument places of predicates. The version presented here is capable of straightforwardly translating natural-language sentences involving defining clauses. A three-valued, (...) model-theoretic semantics for Quarc is presented. Interpretations in this semantics are not equipped with domains of quantification: they are just interpretation functions. This reflects the analysis of natural-language quantification on which Quarc is based. A proof system is presented, and a completeness result is obtained. The logic presented here is capable of straightforward translation of the classical first-order predicate calculus, the translation preserving truth values as well as entailment. The first-order predicate calculus and its devices of quantification can be seen as resulting from Quarc on certain semantic and syntactic restrictions, akin to simplifying assumptions. An analogous, straightforward translation of Quarc into the first-order predicate calculus is impossible. (shrink)

The modern ethical framework demands informed consent for research participation that includes disclosure of material information, as well as alternatives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (COVID-19) results in illness that often involves rapid deterioration. Despite the urgent need to find therapy, obtaining informed consent for COVID-19 research is needed. The current pandemic presents three types of challenges for investigators faced with obtaining informed consent for research participation: (1) uncertainty over key information to informed consent, (2) time (...) and pressure constraints, and (3) obligations regarding disclosure of new alternative therapies and re-consent. To mitigate consenting challenges, primary investigators need to work together to jointly promote urgent care and research into COVID-19. Actions they can take include (1) prior plan addressing ways to incorporate clinical research into clinical practice in emergency, (2) consider patients vulnerable with early deliberation on the consent process, (3) seek Legally Authorized Representatives (LARs), (4) create a collaborative research teams, (5) aim to consent once, despite evolving information during the pandemic, and (6) aim to match patients to a trial that will most benefit them. The COVID-19 pandemic both exacerbates existing challenges and raises unique obstacles for consent that require forethought and mindfulness to overcome. While research teams and clinician-investigators will need to be sensitive to their own contexts and adapt solutions accordingly, they can meet the challenge of obtaining genuinely informed consent during the current pandemic.

I study a market model in which profit-maximizing firms compete in multidimensional pricing strategies over a consumer, who is limited in his ability to grasp such complicated objects and therefore uses a sampling procedure to evaluate them. Firms respond to increased competition with an increased effort to obfuscate, rather than with more competitive pricing. As a result, consumer welfare is not enhanced and may even deteriorate. Specifically, when firms control both the price and the quality of each dimension, and there (...) are diminishing returns to quality, increased competition implies an efficiency loss which is entirely borne by consumers. KEYWORDS. Bounded rationality, industrial organization, multi-dimensional pricing, law of small numbers, market exploitation, obfuscation. (shrink)

Recently, several scholars have argued that governments worldwide should seriously consider using direct human engineering to curb global climate change. Prominent proposals include (1) cognitive enhancement, (2) moral bioenhancement, (3) preference modification, and (4) physiological modification. These direct human engineering programs could alleviate global climate change by reducing the consumption of resources, improving the understanding of the danger of climate change, and increasing moral motivations to adopt eco-friendly behaviors. Yet, each of these proposals raises several ethical concerns. This chapter provides (...) a review of the rationale behind human engineering and the current state of the literature on human engineering and climate change, concluding that at the moment human engineering raises more problems than it solves.

This study investigated inverse preference effects in L2 structural priming of English relative clauses and their potential influences on subsequent learning of target structures. One hundred fourteen Chinese learners of English at a low-to-intermediate proficiency level participated in a structural priming experiment with a pretest-posttest design. The experimental group underwent a priming task in which they orally produced syntactic structures immediately after viewing English object or passive relative clauses as primes, whereas the control group only read sentences unrelated to English (...) relative clauses. A grammaticality judgment task and a sentence completion task were used to measure the inverse preference effect and its subsequent effects on L2 learning. The results showed the presence of structural priming and inverse preference effects in immediate production, which extended to subsequent learning of L2. In subsequent grammaticality judgments and production, L2 learners performed better with English object relative clauses than with English passive relative clauses in comparison with the pretest. The results are discussed in terms of the structural frequency in both L1 and L2 as well as the implicit learning mechanisms of structural priming. (shrink)

Much has been written about the global convergence on constitutional supremacy. Yet, a closer look suggests that while constitutional convergence trends are undoubtedly extensive and readily visible, expressions of constitutional resistance or defiance may in fact be regaining ground worldwide. This may point to a paradox embedded in global constitutionalism: the more expansive constitutional convergence trends are, the greater the likelihood of dissent and resistance are. In this article, I chart the contours of three aversive responses to constitutional convergence: neo-secessionism, (...) nullification, and deference to local authority, and draw on an array of comparative examples to illustrate the distinct logic and characteristics of each of these responses. Taken together, these increasingly common expressions of defiance provide ample evidence that global constitutionalism is not the only game in town. Neo-secessionism, nullification, and other forms of constitutional dissent and “opting out” may thus be viewed as a reaction against the centralization of authority and the decline of the local in an increasingly—constitutionally and otherwise—universalized reality.

Working Memory plays a crucial role in many high-level cognitive processes . The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside (...) of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM. (shrink)

In this paper, finite-time tracking problem of nonholonomic mobile robots for a moving target is considered. First of all, polar coordinates are used to characterize the distance and azimuth between the moving target and the robot. Then, based on the distance and azimuth transported from the sensor installed on the robot, a finite-time tracking control law is designed for the nonholonomic mobile robot by the switching control method. Rigorous proof shows that the tracking error converges to zero in a finite (...) time. Numerical simulation demonstrates the effectiveness of the proposed control method. (shrink)

As a value-led entity, the nonprofit depends on its staff for the delivery of the brand value outsides and thus promoting the brand inside is crucial to the development of the nonprofits. Using a sample of 290 full-time staff working in 270 nonprofits in China, two related studies were conducted. Study 1 aimed to develop and validate a new scale for internal branding in the nonprofit context, while Study 2 aimed to investigate the linking mechanism between internal branding and brand (...) performance with the mediating roles of the person–organization fit and intent to stay with the brand. As predicted, the results revealed that: the nonprofit internal branding scale is a three-dimensional construct that is composed of brand-centered training, internal brand communication, and brand-oriented leadership, internal branding positively predicts POF, IntSB, and brand performance, and POF and IntSB sequentially mediate the internal branding–brand performance relationship. The implications of our findings for internal branding in the nonprofit context are discussed. (shrink)

Remote state preparation is generation of a desired state by a remote observer. In spite of causality, it is well known, according to the Reeh–Schlieder theorem, that it is possible for relativistic quantum field theories, and a “physical” process achieving this task, involving superoscillatory functions, has recently been introduced. In this work we deal with non-relativistic fields, and show that remote state preparation is also possible for them, hence obtaining a Reeh–Schlieder-like result for general fields. Interestingly, in the nonrelativistic case, (...) the process may rely on completely different resources than the ones used in the relativistic case. (shrink)

Defining privacy is a long-sought goal for philosophers and legal scholars alike. Current definitions lack mathematical rigor. They are therefore impracticable for domains such as economics and computer science in which privacy needs to be quantified and computed. This paper describes a game-theoretic framework in which privacy requires no definition per se. Rather, it is an emergent property of specific games, the strategy by which players maximize their reward. In this context, key activities related to privacy, such as methods for (...) its protection and ways in which it is traded, are given concrete meaning. Based in game theory, emergent privacy demonstrates that the right to privacy can be derived, at least in part, on a utilitarian philosophical basis. (shrink)

Looking at Soyoung Kim’s Exile Trilogy, three documentaries centering on ethnic Koreans in Central Asia and specifically the use of archival footages and soundtracks in Sound of Nomad, Arirang, this article considers Kim’s works an organic contribution to the image archive of/about/by the global Korean diaspora while seeking to interrogate the politics of “retro” by turning to what Catherine Russell has approached as “archiveology.” Foregrounding the representation of the transgenerational divas from the “Arirang Ensemble” of the Koryo Theater in Almaty, (...) Kazakhstan, this piece highlights how the divas’ personal stories reconstructed via images, oral accounts, sound recordings, and so forth need to be grasped as an assemblage of affective flows that has complicated the teleological narrative about the Korean diaspora and problematized the Soviet state’s ideocultural representations of the Koryo people.
