We examined whether and how managerial ability affects the relationship between customer concentration and corporate performance. Based on a novel measure of managerial ability, we found that customer concentration has a significant negative effect on corporate performance, while managerial ability can mitigate this effect. The negative effect of customer concentration is only significant in the subsample of low ability and lower efficiency in asset utilization, while the moderating effect of managerial ability is significant for all levels of asset utilization efficiency (...) and more significant for firms with a lower gross margin. The results are robust to numerous robustness tests and endogeneity concerns. Additional analysis of mechanisms shows that in addition to superior operating ability, competent managers select major customers who are more beneficial to their company and decrease the sensitivity of their research and development investment to customers. These findings indicate that the heterogeneity of managerial ability plays an important role in the supplier–customer context when the supplier firm generally faces one or more concentrated customers.

In this article, we study the mural restoration work based on artificial intelligence-assisted multiscale trace generation. Firstly, we convert the fresco images to colour space to obtain the luminance and chromaticity component images; then we process each component image to enhance the edges of the exfoliated region using high and low hat operations; then we construct a multistructure morphological filter to smooth the noise of the image. Finally, the fused mask image is fused with the original mural to obtain the (...) final calibration result. The fresco is converted to HSV colour space, and chromaticity, saturation, and luminance features are introduced; then the confidence term and data term are used to determine the priority of shedding boundary points; then a new block matching criterion is defined, and the best matching block is obtained to replace the block to be repaired based on the structural similarity between the block to be repaired and the matching block by global search; finally, the restoration result is converted to RGB colour space to obtain the final restoration result. An improved generative adversarial network structure is proposed to address the shortcomings of the existing network structure in mural defect restoration, and the effectiveness of the improved modules of the network is verified. Compared with the existing mural restoration algorithms on the test data experimentally verified, the peak signal-to-noise ratio score is improved by 4% and the structural similarity score is improved by 2%.

In a congested large-scale subway network, the distribution of passenger flow in space-time dimension is very complex. Accurate estimation of passenger path choice is very important to understand the passenger flow distribution and even improve the operation service level. The availability of automated fare collection data, timetable, and network topology data opens up a new opportunity to study this topic based on multisource data. A probability model is proposed in this study to calculate the individual passenger’s path choice with multisource (...) data, in which the impact of the network time-varying state on passenger path choice is fully considered. First, according to the number and characteristics of OD candidate paths, the AFC data among special kinds of OD are selected to estimate the distribution of passengers’ walking time and waiting time of each platform. Then, based on the composition of path travel time, its real-time probability distribution is formulated with the distribution of walking time, waiting time, and in-vehicle time as parameters. Finally, a membership function is introduced to evaluate the dependence between passenger’s travel time and the real-time travel time distribution of each candidate path and take the path with the largest membership degree as passenger’s choice. Finally, a case study with Beijing Subway data is applied to verify the effectiveness of the model presented in this study. We have compared and analysed the path calculation results in which the time-varying characteristics of network state are considered or not. The results indicate that a passenger’s path choice behavior is affected by the network time-varying state, and our model can quantify the time-varying state and its impact on passenger path choice.

在中國伊斯蘭教研究中，有“回族四大著作家”（王岱輿、馬注、劉智、馬複初）的說法。馬注思想之所以值得重視和研究，完全與他出生於回族世家，自幼受儒學教育從而在融合伊斯蘭與儒家思想方面，做出了重要貢獻。他的 《清真指南》堪稱伊斯蘭教中國化方面的傑出代表作。當前，世界範圍內伊斯蘭教的賽萊菲耶極其活躍。它在國際政治領域，已經產生了可見的危害；它在思想、文化、宗教領域的流傳，人們同樣不應低估它的嚴重影響。.

According to Hobbes, individuals care about their relative standing in a way that shapes their social interactions. To model this aspect of Hobbesian psychology, this paper supposes that agents have social preferences, that is, preferences about their comparative resource holdings. Introducing uncertainty regarding the social preferences of others unleashes a process of trust-unravelling, ultimately leading to Hobbes’s ‘state of war’. This Trust-unravelling Model incorporates important features of Hobbes’s argument that past models ignore.

This study investigates the mechanism of how sensory experiences influence visitors’ digital engagement with a destination through establishing a strong bond and identification between a destination and tourist utilizing a two-step process. First, visitors’ sensory experiences in a destination are identified through a content analysis of online review comments posted by visitors. Afterward, the effects of those sensory experiences on visitors’ digital engagement through destination dependence and identification with that destination are examined. Findings suggest that sensory experiences are critical antecedents (...) of visitors’ bond and identification with a destination. Visitors’ positive destination-related sensory experiences increase their dependence on and identification with the destination, and this dependence and identification positively influence their digital engagement behavior on social media.

Gitik and Rinot :1771–1795, 2012) proved assuming the existence of a supercompact that it is consistent to have a strong limit cardinal \ of countable cofinality such that \, there is a very good scale at \, and \ fails along some reflecting stationary subset of \\). In this paper, we force over Gitik and Rinot’s model but with a modification of Gitik–Sharon :311, 2008) diagonal Prikry forcing to get this result for \.

Fontanella :193–207, 2014) showed that if \ is an increasing sequence of supercompacts and \, then the strong tree property holds at \. Building on a proof by Neeman, we show that the strong tree property at \ is consistent with \, where \ is singular strong limit of countable cofinality.

Throughout the COVID-19 pandemic, shortages of scarce healthcare resources consistently presented significant moral and practical challenges. While the importance of vaccines as a key pharmaceutical intervention to stem pandemic scarcity was widely publicized, a sizable proportion of the population chose not to vaccinate. In response, some have defended the use of vaccination status as a criterion for the allocation of scarce medical resources. In this paper, we critically interpret this burgeoning literature, and describe a framework for thinking about vaccine-sensitive resource (...) allocation using the values of responsibility, reciprocity, and justice. Although our aim here is not to defend a single view of vaccine-sensitive resource allocation, we believe that attending critically with the diversity of arguments in favor (and against) vaccine-sensitivity reveals a number of questions that a vaccine-sensitive approach to allocation should answer in future pandemics.

Jin Qian Dans son Discours sur la théologie naturelle des Chinois, Leibniz produit une interprétation du premier principe de la philosophie chinoise. Le présent article s’interroge sur les conditions de cette interprétation en la comparant avec la controverse entre Leibniz et Descartes par rapport à la conception de la substance. Il sera montré que, bien que Leibniz utilise un « principe herméneutique » dans son interprétation de la philosophie chinoise, ce principe n’est pas suffisant mais repose sur des conditions plus (...) fondamentales. La comparaison avec la controverse Leibniz-Descartes sur la substance permet d’identifier deux conditions majeures de l’application de ce principe herméneutique, à savoir la théorie dynamique de la substance et la conception de la théologie naturelle comme fondement de la physique, deux points sur lesquels divergent Leibniz et Descartes.

Food prices are a daily concern in many households’ decision-making, especially when people want to have healthier diets. Employing Bayesian Mindsponge Framework (BMF) analytics on a dataset of 710 Indonesian citizens, we found that people from wealthier households are less likely to have concerns about food prices. However, the degree of health considerations in food consumption was found to moderate against the above association. In other words, people of higher income-based social classes may worry more about food prices if they (...) care more about the health impacts of their food choices. These findings provide more insights for policymakers on the psychological aspects of promoting the balance between finance and health in food consumption. (shrink)

We develop a theory of necessity operators within a version of higher-order logic that is neutral about how fine-grained reality is. The theory is axiomatized in terms of the primitive of *being a necessity*, and we show how the central notions in the philosophy of modality can be recovered from it. Various questions are formulated and settled within the framework, including questions about the ordering of necessities under strength, the existence of broadest necessities satisfying various logical conditions, and questions about (...) their logical behaviour. We also wield the framework to probe the conditions under which a logicist account of necessities is possible, in which the theory is completely reducible to logic. (shrink)

Studies have shown that internal whistleblowing could be utilized as an effective way to stop an organization’s unethical behaviors. This study investigates the relationship between ethical leadership and internal whistleblowing by focusing on the mediating role of employee-perceived organizational politics and the moderating role of moral courage. An analysis of data collected at three phases indicates that employee-perceived organizational politics partly mediates the relationship between ethical leadership and internal whistleblowing. Also, moral courage is found to moderate the effect of employee-perceived (...) organizational politics on internal whistleblowing and the indirect effect of ethical leadership on internal whistleblowing via employee-perceived organizational politics. Theoretical and practical implications of these results are discussed. (shrink)

This dissertation contextualizes the emergence of the Church of Light by Tadao Ando within the Japanese religio-philosophical tradition of nothingness. The idea of nothingness was revived during the first half of the twentieth-century by Kitaro Nishida with two cultural ramifications in the post-war period: a series of dialogues on the points of convergence and divergence between nothingness and the God of Christianity, and an architectural art movement called Monoha, or l'Ecole de Choses. Under the concept of "structuring emptiness," Monoha attempted (...) to restore perceptual depth where dichotomous semiotic representation is overcome through shintaisei, the co-originating corporeal fabric between the subject and object. This two-fold mapping, theological and architectural, not only illuminates the post-war cultural milieu from which Ando's church of spatial emptiness emerged, but also locates the church within the legacy of Nishida's nothingness. ;Nishida's philosophy of nothingness offers a perceptual theory of the "dialectic of self-negation" enacted by shintai, "the actively knowing body." Shintai is the agent of emptying selfhood by functioning as 'the sensational capacity to be filled by' the world. Shintai concretizes the perceptual matrix of co-emergence between the interiority of selfhood and the outside world. When its sensational capacity overflows, shintai enters into the realm of creative action to accommodate the surplus. The figure thus created is not a sign embodying subjective intentions, but constitutes the corporelly-inscribed, pre-reflective experiential datum of the world. Nishida called such a figure "the pure body of the artist," implying its apprehension not as the other in unknowable confrontation, but as the extended self. ;The dissertation examines how this notion of self-renunciatory perception through shintai opens a new hermeneutic horizon for the Church of Light. The church presents an unprecedented conjunction between emptiness, based on the reductive removal of signs, and the cross of light. This seemingly contradictory integration confronts the modern degradation of the cross into an atrophied sign of Christianity and seeks to retrieve its fully efficacious symbolic power. The emptiness contributes to the revival of a deeper communicative mode as shintai by negating the habituated perception pivoted upon the dichotomy between the deciphering subject and the semiotic elements. The perception of light, a natural thing rather than a sign, which infiltrates the cross, is a preliminary ritual to save the perception from the paradigm of the semiotic representation. Shintai, the self-emptying corporeality, resonates with and becomes penetrated by, rather than subjectivizes, the light. On this restored perceptual depth, the cross is perceived not as a sign, but as a part of the pre-reflective, ontological datum constructed and apprehended by shintai. This perceptual experience endorses the associational similarity between the pre-Christian datum predicated upon shintai as the agent of the self-renunciatory subjectivity and Christianity with its theology of the self-transcending love of kenosis.

: In his philosophy of nothingness, Kitar Nishida illuminates the matrix of transformation of the world ‘‘from the Created to the Creating’’ (tsukuru mono kara tsukurareta mono e) through shintai, or the body. In this matrix, shintai enters into the stage of an action-sensation continuum and emerges as the immaculate iconic tool of nothingness to create new figures as extended self. This idea of shintai has resonance with the development of postwar art in Japan. The ‘‘Space of Transparency’’ put forth (...) by Ufan Lee, the leader of Monoha, is the principal example. This essay investigates Nishida’s notion of shintai and its influence on Lee’s theory of art. (shrink)
