One of the most efficient nondestructive methods for pipeline in-line inspection is magnetic flux leakage inspection. Estimating the size of the defect from MFL signal is one of the key problems of MFL inspection. As the inspection signal is usually contaminated by noise, sizing the defect is an ill-posed inverse problem, especially when sizing the depth as a complex shape. An actor-critic structure-based algorithm is proposed in this paper for sizing complex depth profiles. By learning with more information from the (...) depth profile without knowing the corresponding MFL signal, the algorithm proposed saves computational costs and is robust. A pinning strategy is embedded in the reconstruction process, which highly reduces the dimension of action space. The pinning actor-critic structure helps to make the reward for critic network more efficient when reconstructing the depth profiles with high degrees of freedom. A nonlinear FEM model is used to test the effectiveness of algorithm proposed under 20 dB noise. The results show that the algorithm reconstructs the depth profile of defects with good accuracy and is robust against noise. (shrink)

Autonomous learning capacity is a key competency that supports teachers’ professional development. In this study, a stratified sampling method was used to recruit 396 junior and senior high school mathematics teachers in T city, one of the provincial city in China. A questionnaire with high reliability and validity developed prior to the study by the researchers was employed to measure their autonomous learning capacity and differences across groups. Twelve teachers were then selected for interviews. The results showed satisfactory overall performance. (...) By subdimension, teachers’ performance was the best in the development of study plans, followed by evaluation of learning outcomes, while they needed improvement in learning habit formation and proficiency in using learning methods. Furthermore, the analysis of differences across groups indicated that for autonomous learning capacity, female teachers were significantly better than their male peers; junior high school teachers were better compared to those in senior high school; teachers aged 41–50 underperformed those aged 51 and above; teachers who work in rural areas and townships did not perform worse than urban teachers; and those with doctoral degrees did not demonstrate considerable advantage over others. There were no significant differences in the overall autonomous learning capacity across years of teaching and job title groups. However, in the subdimensions, those with 21–30 years of teaching experience had lower proficiency in using learning methods and evaluation of learning outcomes, and teachers with senior titles did not demonstrate expected advantages in learning habit formation.

Tang Zhen (1630-1704) est l'un des philosophes et écrivains éminents du XVIIe siècle chinois. Sa jeunesse coïncida avec une des périodes les plus sombres et les plus dramatiques de l'histoire chinoise : l'effondrement de la dynastie Ming et la venue au pouvoir des Mandchous. Après une brève carrière officielle (il est sous-préfet au Shanxi en 1671), il redevient simple particulier et vit jusqu'à sa mort dans la misère ; il n'entretient de contacts qu'avec de rares savants de l'époque. En (...) revanche, dans son isolement, il consacre trente ans à la rédaction d'un seul grand ouvrage, le Qianshu, ou Ecrits d'un sage encore inconnu, qui comprend deux groupes d'essais : sur la sagesse, et sur la mise en ordre du monde. Il y rassemble et y condense, dans un style remarquable, les pensées, jugements et réflexions de toute une vie axée sur le perfectionnement moral, l'aspiration à la vérité et à la sérénité. Tempérament entier et intègre, soucieux d'application pratique, il aborde tous les sujets fondamentaux de l'éthique, de la politique, de la philosophie. Longtemps ignoré dans son pays, il n'a été redécouvert qu'au milieu de ce siècle, et sa critique violente de l'absolutisme l'a rendu célèbre. Ses pages passionnées, où la réflexion abstraite se mêle à d'innombrables exemples réalistes, sont attachantes, émouvantes : on y voit un esprit à l'œuvre face au monde ; comme il le dit " l'esprit est une chose merveilleuse ", et le sien, éclairé et souvent proche de celui de nos philosophes des Lumières, travaille pour lui-même, avec fécondité, avec bonheur. L'œuvre de Tang Zhen est traduite (avec tous les éclaircissements nécessaires) pour la première fois dans une langue occidentale. Traduite, dirons-nous, fraternellement, par un esprit proche du sien, à la fois exigeant, sobre, et tolérant : celui du maître de la sinologie française, Jacques Gernet, qui nous propose ici une découverte majeure.

Despite urgent calls for more research on the integration of business ethics and the meaning of work, to date, there have been few corresponding efforts, and we know surprisingly little about this relationship. In this study, we address this issue by examining when and for whom ethical leadership is more effective in promoting a sense of work meaningfulness among employees, and their subsequent work attitudes. Drawing on the contingency theories of leadership and work meaningfulness literature, we speculate that both employees’ (...) core self-evaluation and perceived organizational support moderate the relationship, but in different ways, and these associations carry over to employees’ subsequent work attitudes in terms of job satisfaction, organizational commitment and turnover intention. We test our hypotheses with two-wave survey data collected from 377 employees. Results indicate that ethical leadership is effective in eliciting work meaningfulness and attitudes for employees higher in CSE or when POS is lower, and ineffective for those lower in CSE or when POS is higher. A supplementary analysis reveals a three-way interaction between ethical leadership, CSE and POS in predicting a sense of work meaningfulness and subsequent work attitudes. Our research cautions that ethical leadership is not a universally positive practice; it can be ineffective or even have a negative impact under some circumstances. (shrink)

The proposition _zhengyan ruo fan_ 正言若反 (straightforward words seem paradoxical) embodies Laozi’s 老子 linguistic self-consciousness about the expression of ideas, and the way of thinking presented by this proposition is also commonly considered by ancient exegetes to be reflected in the linguistic expressions of Daoism. As such, contemporary Chinese scholars have paid great attention to this proposition and have discussed it enthusiastically. However, researchers have not yet reached a consensus on how to interpret this proposition. The divergence of views among (...) scholars is manifested both in the interpretation of this proposition according to the context it appears in and how to locate its role and status in Laozi’s thought. In terms of the interpretation of the text, scholars have different views on the chapter to which _zhengyan ruo fan_ should be attributed and the precise meaning of this proposition in the chapter where it appears. Scholars have also paid attention to linguistic phenomena involved in the _Laozi_, the theoretical motives behind these linguistic phenomena, and the way they relate to other important concepts in _Laozi._ There are many differences in the discussed opinions. In this article, an overview of these different views and an assessment of the merits and flaws of each interpretation in light of the textual basis and theoretical feasibility is provided in order to increase understanding of the linguistic expression and the thought behind it, in regard to _Laozi_ in particular and even Daoism in general.

Dysregulation of lipid metabolism is a commonly observed feature associated with metabolic syndrome and leads to the development of negative health outcomes such as obesity, diabetes mellitus, non‐alcoholic fatty liver disease, or atherosclerosis. Time‐restricted feeding/eating (TRF/TRE), an emerging dietary intervention, has been shown to promote pleiotropic health benefits including the alteration of diurnal expression of genes associated with lipid metabolism, as well as levels of lipid species. Although TRF likely induces a response in multiple organs leading to the modulation of (...) lipid metabolism, a majority of the studies related to TRF effects on lipids have focused only on individual tissues, and furthermore there is a lack of insight into potential underlying mechanisms. In this review, we summarize the current insights regarding TRF effects on lipid metabolism and the potential mechanisms in adipose tissue, liver, skeletal muscle, and heart, and conclude by outlining possible avenues for future exploration.

A nonlinear coupled wing model subject to unknown external disturbances is proposed in this paper. Since the model is modeled by partial differential equations, the traditional control design scheme based on the ordinary differential equation model is not applicable, and the control law design becomes very complex. In this paper, a new antidisturbance boundary control scheme based on a finite time convergent disturbance observer is proposed. The control laws are designed based on the new disturbance observers to make the external (...) disturbance errors converge to zero in a finite time and ensure the uniformly bounded stability of the controlled system. Finally, the effectiveness of the controllers and the finite-time convergence of disturbance errors are verified by the simulation and comparison. (shrink)

Understanding how teacher leaders are engaged in curriculum affairs is critical with the implementation of instructional decentralization. The current study adopts a qualitative approach to investigate Teaching Research Group leaders’ involvement in curriculum leadership in the Chinese context. It explores the conceptions of TRG leaders by interviewing 20 of them, observing four meetings held by TRG leaders, and collecting 10 extracts from appraisal summaries of TRG leaders in secondary schools in China. Drawing on the findings, this paper examines the characteristics (...) of TRG leader’s engagement in CL. More importantly, data highlighted significant problems the participants perceived and faced in their work as TRG leaders, which consisted of amplifying the necessity for empowering TRG leaders and identifying the phenomenon that said leaders are less empowered and less motivated to undertake the CL role. The results add to the international body of knowledge on the teachers’ engagement in CL. (shrink)

Competitive pressures, resource constraints, high shareholder/stakeholder expectations, and other dynamics may lead to organizations putting pressure on employees to act unethically to meet goals. Yet, the effects of this pressure on employee health and factors that can abate it are unclear. Based on the job demands-resources model, this study examines whether, how, and when organizational ethical pressure harms employees' psychological and physical health and what factors can buffer its negative effects. According to the findings of a two-wave lagged data study (...) involving 212 healthcare employees, results show that organizational ethical pressure causes ethical strain in employees, resulting in both psychological and physical health problems, with these effects less pronounced when employees have higher levels of ethical efficacy. An integrated effect was also discovered, in which employees' ethical efficacy increases when led by a more ethical leader, thereby buffering the effect of ethical pressure on ethical strain and health problems. Overall, our research identifies organizational ethical pressure as a significant threat to employee health and provides preliminary approaches to mitigate its effects. (shrink)

Extant studies of corporate hypocrisy have largely overlooked its implications for employees until recently. Drawing upon social information processing theory, we theorize the impact of corporate hypocrisy on employee silence—an employee behavior potentially detrimental to both organizations and society, as well as the underlying mediating and moderating mechanisms. We empirically tested our hypotheses with two studies. In Study 1, we found that corporate hypocrisy was positively related to employee silence through both employee cognitive trust and employee prosocial motivation. In Study (...) 2, we revealed that consumer pressure weakened the mediating roles of employee cognitive trust and prosocial motivation, while regulatory pressure strengthened these roles. Overall, this study sheds light on whether, how, and when employees remain silent when they perceive corporate hypocrisy. Implications for theory and practice are discussed. (shrink)

There is a discrepancy between human rights theories and the contemporarily international human rights practice. The discrepancy is not only generated by theexpectable distance between the ideal and the real world, but also generated by the consequence which the orthodox conception of human rights theories cannot proper account for the role of human rights in the contemporarily international relations. Furthermore, the orthodox conception cannot be compatible with political pluralism; for it often justify the ground of human rights with human dignity (...) and presuppose the independence and the autonomy of persons. I propose that the orthodox conception fails to supply two good reasons for dispelling the doubt on the western cultural imperialism---one is human rights may beaccepted by the different cultures and moral codes with the method of overlapping consensus; the other is the orthodox conception does not prefer to liberal values. Instead of the orthodox conception, I suggest that we have to justify the ground of human rights according to the political pluralistic conception if we hope human rights can be universalized in the world. The political pluralistic conception will not only avoid the doubt on the western cultural imperialism, but alsoconsist with the role of human rights in the contemporarily international relations.

Let G be a connected graph with minimum degree δ G and vertex-connectivity κ G. The graph G is k -connected if κ G ≥ k, maximally connected if κ G = δ G, and super-connected if every minimum vertex-cut isolates a vertex of minimum degree. In this paper, we present sufficient conditions for a graph with given minimum degree to be k -connected, maximally connected, or super-connected in terms of the number of edges, the spectral radius of the graph, (...) and its complement, respectively. Analogous results for triangle-free graphs with given minimum degree to be k -connected, maximally connected, or super-connected are also presented. (shrink)

Based on the concept of “passengers self-help hubbing,” we build a flight schedule optimization model where maximizing the number of feasible flight connections, indicating transfer opportunities, as one objective and minimizing total slot displacements as the other objective. At the same time, the “Demand Smoothing Model” is introduced into the flight schedule optimization model to reduce the queuing delays for arrival and departure flights. We take into account all aircraft itineraries, the difficulty level of schedule coordination, and the maximum displacement (...) of any single flight acceptable to airlines when optimizing flight schedule. Given an original schedule, the model produces a feasible modified schedule that obeys the slot limits specified for an airport without canceling any flights, increases transfer opportunities, and improves on-time performance for hub airports while reducing interference with airline scheduling preferences. The model was verified with the operating data of the Urumqi international airport, and the results show that minor adjustments to flight schedules can increase the transfer opportunities of the airport and significantly reduce flight queuing delays.

With the increasing importance of the internet to our everyday lives, questions are rightly being asked about how its' use affects our wellbeing. It is important to be able to effectively measure the effects of the online context, as it allows us to assess the impact of specific online contexts on wellbeing that may not apply to offline wellbeing. This paper describes a scoping review of English language, peer-reviewed articles published in MEDLINE, EMBASE, and PsychInfo between 1st January 2015 and (...) 31st December 2019 to identify what measures are used to assess subjective wellbeing and in particular to identify any measures used in the online context. Two hundred forty studies were identified; 160 studies were removed by abstract screening, and 17 studies were removed by full-text screening, leaving 63 included studies. Fifty-six subjective wellbeing scales were identified with 18 excluded and 38 included for further analysis. Only one study was identified researching online wellbeing, and no specific online wellbeing scale was found. Therefore, common features of the existing scales, such as the number and type of questions, are compared to offer recommendations for building an online wellbeing scale. Such a scale is recommended to be between 3 and 20 questions, using mainly 5-point Likert or Likert-like scales to measure at least positive and negative affect, and ideally life satisfaction, and to use mainly subjective evaluation. Further research is needed to establish how these findings for the offline world effectively translate into an online measure of wellbeing. (shrink)

(2) Conduct questionnaire surveys and interview studies on primary school students, students' parents, heads (...) of primary out-of-school art education institutions, and governmental supervisors of primary out-of-school art education institutions, respectively, to summarise the current problems. (3) The questionnaire survey data and interviews were analysed and summarised to provide development suggestions for primary school students' out-of-school art education and training institutions, which will serve as a guide for the development of primary school students' out-of-school art education institutions in urban China and have a universal value. The tool used to collect data was the WeChat app "Questionnaire Star". The data were analysed through descriptive statistics and content analysis. The results of the study are as follows; Primary school students have a positive attitude towards the overall improvement of their abilities through participation in off-campus art education training. Achievements, gains and expectations influence the interest of primary school students in participating in the training, and they hope that organisations can carry out a variety of practical activities. Parents have a positive attitude towards their children's participation in extracurricular arts education and training, but their satisfaction with the extracurricular arts education and training organisations is not high, and they are not clear about their children's development plans. Most of the organisations are able to provide a suitable learning environment for students, but there are differences in hardware equipment, teacher level and teaching effectiveness among the organisations.

People’s comfort with and acceptability of artificial intelligence (AI) instantiations is a topic that has received little systematic study. This is surprising given the topic’s relevance to the design, deployment and even regulation of AI systems. To help fill in our knowledge base, we conducted mixed-methods analysis based on a survey of a representative sample of the US population (_N_ = 2254). Results show that there are two distinct social dimensions to comfort with AI: as a peer and as a (...) superior. For both dimensions, general and technological efficacy traits—locus of control, communication apprehension, robot phobia, and perceived technology competence—are strongly associated with acceptance of AI in various roles. Female and older respondents also were less comfortable with the idea of AI agents in various roles. A qualitative analysis of comments collected from respondents complemented our statistical approach. We conclude by exploring the implications of our research for AI acceptability in society.

This paper is intended to make a more comprehensive exploration and introduction of the important concept of existence in Aquinas's philosophy and segmented into five parts: first, a generalization of "existence"; second, a glimpse of the historical background precedent to Aquinas's time, including Greek philosophy and medieval philosophy; third, the meaning and importance of existence; fourth, Aquinas's analysis of existence in his Commentaries on Aristotle; and fifth, Aquinas's theory of personality. Due to the limits of volume, here we can only address the first three parts. From these headings, it's easily seen and should be noted that the references in the paper are mostly from Commentary on Aristotle's Metaphysics. (shrink)
