Because they are key components of aircraft, improving the safety, reliability and economy of engines is crucial. To ensure flight safety and reduce the cost of maintenance during aircraft engine operation, a prognostics and health management system that focuses on fault diagnosis, health assessment, and life prediction is introduced to solve the problems. Predicting the remaining useful life is the most important information for making decisions about aircraft engine operation and maintenance, and it relies largely on the selection of performance (...) degradation features. The choice of such features is highly significant, but there are some weaknesses in the current algorithm for RUL prediction, notably, the inability to obtain tendencies from the data. Especially with aircraft engines, extracting useful degradation features from multisensor data with complex correlations is a key technical problem that has hindered the implementation of degradation assessment. To solve these problems, deep learning has been proposed in recent years to exploit multiple layers of nonlinear information processing for unsupervised self-learning of features. This paper presents a deep learning approach to predict the RUL of an aircraft engine based on a stacked sparse autoencoder and logistic regression. The stacked sparse autoencoder is used to automatically extract performance degradation features from multiple sensors on the aircraft engine and to fuse multiple features through multilayer self-learning. Logistic regression is used to predict the remaining useful life. However, the hyperparameters of the deep learning, which significantly impact the feature extraction and prediction performance, are determined based on expert experience in most cases. The grid search method is introduced in this paper to optimize the hyperparameters of the proposed aircraft engine RUL prediction model. An application of this method of predicting the RUL of an aircraft engine with a benchmark dataset is employed to demonstrate the effectiveness of the proposed approach. (shrink)

Both corruption and subjective wellbeing are of concern to academics and governments. Although some evidence suggests that corruption deteriorates subjective wellbeing, the relationship between perception of official corruption and subjective wellbeing is still unknown. This study aims to examine the link between perceived official corruption and subjective wellbeing in the context of China and whether satisfaction with government performance has a mediating effect in the process. Based on data from China General Social Survey, a structural equation model was used to (...) test the hypotheses. The results of 3,033 Chinese respondents suggest that perception of official corruption is negatively related to subjective wellbeing, and satisfaction with government performance plays a mediating role in the relationship between perception of official corruption and subjective wellbeing.

Although humility is a hallmark of many beloved and respected leaders, yet little is known about the impact of humble leadership on employee job performance. Drawing on social exchange theory and attribution theory, the current study suggests a moderated mediation model to elucidate how and when humble leadership encourages follower job performance. Analyses of multilevel, multisource data from 204 subordinates and 68 supervisors showed that humble leadership and employee job performance via supervisor–subordinate guanxi is moderated by perceived leader integrity, such (...) that the indirect and positive relationship between humble leadership and employee job performance via supervisor–subordinate guanxi would be strengthened when perceived leader integrity is high rather than low. Theoretical and practical implications as well as limitations and future directions are discussed. (shrink)

Supervisors regularly make disciplinary decisions in organizations, and some supervisors may choose to act leniently. While research on supervisor discipline has shown its impact on transgressing employees, less is understood about how third-party observers interpret and react to supervisor leniency. To address this lack of knowledge, we utilize motive attribution theory and the literature on gender norms, and adopt a mixed methods design to investigate how third-party employees morally evaluate supervisor leniency based on their motive attributions of supervisor leniency, as (...) well as the consequences associated with such moral evaluations. Study 1 first uses a micro-narrative procedure and an inductive analysis to demonstrate varied altruistic (e.g., empathy, punishment calibration, etc.) and instrumental motives (e.g., image maintenance, easier than punishment, etc.) that observing employees attribute to supervisor leniency. Based on this finding, we predict that perceived altruistic (instrumental) motives are associated with lower (higher) immorality evaluations, leading to more (less) supervisor-directed OCB and less (more) gossip, and these effects are contingent on supervisor gender such that these relationships are stronger for female supervisors. The results of Study 2 (i.e., a vignette-based experiment) and Study 3 (i.e., an event-contingent survey study) provide support for our predictions. Our findings contribute to the literature of supervisor leniency by highlighting the roles of motive attribution and supervisor gender in determining employee moral evaluations of leniency and the downstream consequences of such evaluations.

Out of the consideration of the same artistic essence and aesthetic function of drama and opera as theater, many directors devoted their lives to building a "golden bridge" between drama and opera: on the one hand, to maintain the traditional characteristics of opera, but "to make use of new ideas, new techniques, and new organization, so that the face of the old opera can be renewed". On the other hand, their early practice of new drama also made them realize that (...) Chinese drama, which lacked roots, "in terms of scriptwriting and acting, its only master was the Chinese opera. On the other hand, their early practice of new drama also made them realize that Chinese drama, which lacked roots, was "still the only master of Chinese opera in terms of scriptwriting and performance" and therefore needed to draw on the aesthetic spirit and artistic techniques of traditional opera, and in their later years they hoped that drama would "create the latest and most beautiful dramatic art on the basis of tradition". Many directors have left an important legacy for the 20th century Chinese theater by their thinking about and defending the aesthetic nature of theater and its "independent and dignified" artistic status, as well as by their important ideas and remarkable practice of fusing drama and opera to create modern Chinese national theater. It is of great importance to evaluate the effect of fusion. In this paper, we study the deep integration effect measurement of traditional drama and modern drama directing art based on intelligent computing and time-series data analysis, which effectively solves this problem.

Since the outbreak of the COVID-19 pandemic, the physical and mental health of older adults has been threatened. Promoting physical and mental health through physical activity has therefore become a strategy for healthy aging. In order to better understand the impact of the participation of older adults in physical activity, this paper selects different types of physical activity, and examines the relationship between them and subjective well-being through the analysis of the mediation effect of outdoor exercise environment and the regulating (...) effect of exercise form. In this cross-sectional study, a questionnaire survey was conducted in mainland China. The main data come from 903 older adults in five urban areas in Chengdu, Sichuan Province. The surveys were carried out using the Physical Activity Rating Scale, Newfoundland Subjective Well-Being Scale, Exercise Environment Scale, and Exercise Form Scale. SPSS was used for statistical analysis, linear regression analysis was adopted for processing data, and AMOS was used to establish a mediation model. The mediating variable is the outdoor exercise environment, and the moderating variable is exercise form; gender, age, education level, and monthly income were used as control variables. The study results showed that different physical activities were significantly, positively correlated with the subjective well-being of older adults ; among the activities, tai chi had the strongest effect on the subjective well-being of older adults. Outdoor exercise environment played a mediating role between different physical activity types and subjective well-being of older adults [tai chi: β = 0.030, 95% CI ; health qigong: β = 0.018, 95% CI ; walking and jogging: β = 0.034, 95% CI ]. Exercise form moderated the subjective well-being of older adults in different physical activities. The results of this study demonstrate that the outdoor exercise environment plays a mediating role between different physical activities and the subjective well-being of older adults, and the form of exercise can also moderate the impact of different physical activities on the subjective well-being of older adults. This study has enlightening significance for psychological intervention with older adults facing stress, anxiety and depression. (shrink)

In response to the lack of research on the online social network structure of athletes, elements of research on the online social network structure of athletes were constructed based on the whole network perspective and through the study of the characteristics of the whole online social network structure of athletes, in order to provide reference for the physical and mental health development of athletes from a new perspective. Data were collected through questionnaires, and several software programs were used to preprocess (...) and analyse the collected data. Through the analysis of the online whole network structure, it was found that the network density of the online support network was generally greater than that of the online discussion network, and athletes still showed stronger practical support demands and behaved more rationally in the process of training and learning life, while from the perspective of the relationship structure, the athletes’ family and classmates’ online support is weaker than that in previous studies; in terms of the whole network, strong relationships still dominate in this population, while attention should be paid to the impact of weak relationships.

O artigo trata da esfera pública, opinião pública e liberdade de imprensa segundo G. W. F. Hegel como formas de mediação entre o estado e o indivíduo e expressão da liberdade individual ou coletiva. A partir do exame dos Princípios de Filosofia do Direito e das Lições sobre a filosofia do Direito editadas por K.-H. Ilting, afirma-se a idéia de que Hegel não foi um defensor da censura do estado autoritário prussiano, mas da liberdade de expressão do indivíduo no contexto (...) da sociedade política. (shrink)

The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distribution of ESTs, construct a consensus map of group 2 ESTs, investigate synteny, examine patterns of duplication, and assess the colinearity with rice (...) of ESTs assigned to the group 2 consensus bin map. A total of 2600 loci generated from 1110 ESTs were mapped to group 2 chromosomes by Southern hybridization onto wheat aneuploid chromosome and deletion stocks. A consensus map was constructed of 552 ESTs mapping to more than one group 2 chromosome. Regions of high gene density in distal bins and low gene density in proximal bins were found. Two interstitial gene-rich islands flanked by relatively gene-poor regions on both the short and long arms and having good synteny with rice were discovered. The map locations of two ESTs indicated the possible presence of a small pericentric inversion on chromosome 2B. Wheat chromosome group 2 was shown to share syntenous blocks with rice chromosomes 4 and 7. (shrink)

This report describes the rationale, approaches, organization, and resource development leading to a large-scale deletion bin map of the hexaploid wheat genome. Accompanying reports in this issue detail results from chromosome bin-mapping of expressed sequence tags representing genes onto the seven homoeologous chromosome groups and a global analysis of the entire mapped wheat EST data set. Among the resources developed were the first extensive public wheat EST collection. Described are protocols for sequencing, sequence processing, EST nomenclature, and the assembly of (...) ESTs into contigs. These contigs plus singletons were used for selection of distinct sequence motif unigenes. Selected ESTs were rearrayed, validated by 5′ and 3′ sequencing, and amplified for probing a series of wheat aneuploid and deletion stocks. Images and data for all Southern hybridizations were deposited in databases and were used by the coordinators for each of the seven homoeologous chromosome groups to validate the mapping results. Results from this project have established the foundation for future developments in wheat genomics. (shrink)

This research aims, first of all, to establish that Abû Hanîfa's (d. 150/767) positive view on the issue of performing wudû’ with nabîdh of date is correct, and then to reveal Abû Hanîfa's dalîls on this subject. The issue of wudû’ with nabîdh of date is controversial among early Hanafî jurists, and the jurist who expressed a positive opinion on this issue is Abû Hanîfa, the founding imam of the madhhab. The opinion that wudû’ can be performed with nabîdh of (...) date is the strong opinion of Abû Hanîfa mentioned in zâhir al-riwâya. The riwâya reported by Nûh bin Abi Maryam (d. 173/789) stating that Abû Hanîfa reneged on this view is not strong enough to oppose the view in zâhir al-riwâya. For this reason, it is not a correct approach to ignore the view in zâhir al-riwâya based on this riwâya. As a matter of fact, Abû Hanîfa's view of zâhir al-riwâya is conveyed in many of the classical Hanafî texts such as Mukhtasar al-Karkhi and Mukhtasar al-Tahâwî. Although the majority of Hanafî jurists preferred the view of Abû Yûsuf (d. 182/798), a significant group of Hanafî jurists such as Jassâs (d. 370/981), Kâshânî (d. 587/1191) and ‘Aynî (d. 855/1451) He supports Abû Hanîfa's view. Therefore, there are two views on the issue in Hanafî fıqh. In the literature, the dalîls of Abû Hanîfa's view is not available as a whole in a single source, but is scattered in many Hanafî fiqh sources. The Hanafî jurist Jassâs is the one who deals with the mentioned dalîls in the most comprehensive way in his many works. For this reason, the subject was examined by focusing on Jassâs's dalîls. Jassâs' istidlâls regarding the issue of wudû’ with nabîdh of date also mean defending Abû Hanîfa against other Hanafî jurists such as Abu Yusuf and Imâm Muhammad (d. 189/805). Jassâs' insistent attitude on this issue and his passionate counter-answers prove how much he deserves the title of defense. For the relevant determination, Hanafî fiqh classics are centered. Because the jurists who argue that wudû’ can be made with the nabîdh of date are among the Hanafî jurists. Then, the positive and negative approaches of the jurists about the nabîdh of date are given. Starting from the early Hanafî jurists, the views of the sahâbîs, the tâbi'ûn and many later jurists on the subject are included. The approach of the four madhhabs of fiqh is also examined in this section. Then, the istidlâls of Jassâs, which is the main subject of the research, were emphasized. It is seen that Jassâs' istidlâls have three main pillars: âya, hadîth and idjma. As a âya, the 6th âya of the sûra of Mâida, as a hadîth, the hadîth of ‘Abd Allâh bin Mas'ûd (r.a.) and as a idjma, the the sahâbîs idjma tries to showas references. The most controversial dalîl is undoubtedly the hadiths of Ibn Mas'ud (r.a.). Jassâs opposes those who claim that the hadîth is da‘îf and discusses the hadîth with its detailed tarîks and argues that this hadîth is sahîh. (shrink)

Resumo O entendimento de Friedrich Nietzsche sobre Friedrich Schiller é bem conhecido e culmina em 1888, na desqualificação que se tem com “Schiller: ou o trompetista moral de Säckingen”. Mas é sabido que suas considerações são contraditórias, mudando com frequência nas diferentes etapas de sua vida produtiva. A monografia de Nicholas Martin marca um ponto de viragem no que diz respeito a este tema, refutando a disseminada compreensão de que somente o jovem Nietzsche teria experimentado admiração por Schiller, depois vindo (...) a assumir distância cada vez maior. A dívida de Nietzsche para com Schiller, segundo Martin, é constante, e manifesta-se sobretudo em sua recepção das cartas estéticas. O que se pretende fazer ver aqui, seguindo a tradição de Wolfgang Riedel, é que o ensaio Sobre a poesia ingênua e sentimental [Über naive und sentimentalische Dichtung] é tão ou mais importante neste contexto sobretudo quando dirigimos nosso enfoque para o contexto da crítica cultural. Várias declarações de Nietzsche, por exemplo, formulada em 1870, “não estou em condições de empregar essa terminologia esplendorosamente schilleriana para o inteiro e mais amplo domínio de toda a arte”, confirmam tal suposição, e uma vez que, no mesmo momento de elaboração de O nascimento da tragédia no espírito da música, ele se propõe a “[…] fortalecer o conceito do ingênuo e do sentimental”, tem-se justificada a intenção de relacionar ambas as obras-chave de ambos os Dichterphilosophen [filósofos poetas] do ponto de vista da crítica cultural.Friedrich Nietzsche's opinion about Friedrich Schiller is well known and culminates in 1888 in the disqualification “Schiller: oder der Moral-Trompeter von Säckingen”, but at the same time it is recognized that his considerations are contradictory and that they change in the different moments of his productive life. Nicholas Martin's study from 1996 marks a caesura in this subject by refuting the widespread view that only the young Nietzsche experienced admiration for Schiller and that there was a growing distance afterwards. Nietzsche's debt to Schiller, according to Martin, is constant and is manifested above all in his reception of the aesthetic letters. We would like to demonstrate in the tradition of Wolfgang Riedel that the essay Über naive und sentimentalische Dichtung is equally or even more important in this context, especially when it is approached from the standpoint of cultural criticism. Several statements by Nietzsche, such as the one formulated in 1870 “Ich bin nicht im Stande, jene herrliche Schillersche Terminologie auf das ganze weiteste Bereich aller Kunst anzuwenden” confirm this assumption, and when, at the very moment when Die Geburt der Tragödie aus dem Geist der Musik was being prepared, Nietzsche proposed that the “[…] Begriff des Naiven und des Sentimentalistischen ist zu steigern”, the attempt to link both key works of the two Dichterphilosophen from the point of view of cultural criticism is justified.

This book traces a most obscure and yet most intriguing theme concealed in Heidegger’s thinking and work, which has hitherto not yet been made the focus of a thorough and sustained investigation: that is, the emergence and course of Heidegger’s interest in East Asian thought and of his reflection on East-West dialogue. Lin Ma covers such complex issues as Heidegger’s thoughts on language, Being, technology, the other beginning, and the journey abroad, with a view to their implications for East-West dialogue. (...) It reveals the significance of his remarks on the early Greek’s confrontation with the Asiatic, and presents contextualized interpretations of his fleeting references to the topic of East-West dialogue and of his encounter with the Daodejing. Finally, it delves into "A dialogue on language" and exposes the strains and tensions that accompany Heidegger’s extension of dialogue and the Same, the two notions central to his thought, to the question of East-West dialogue. In the end, Lin Ma concludes that Heidegger’s fundamental concerns and philosophical orientations as articulated in terms of the history of Being and the other beginning have restricted him from engaging more seriously with the irresolvable and yet enduring issue of East-West dialogue.

We present a dynamic approach to Peirce’s original construal of abductive logic as a logic of conjecture making, and provide a new decidable, contraction-free and cut-free proof system for the dynamic logic of abductive inferences with neighborhood semantics. Our formulation of the dynamic logic of abduction follows the philosophical and scientific track that led Peirce to his late, post-1903 characterization of abductive conclusions as investigands, namely invitations to investigate propositions conjectured at the level of pre-beliefs.
