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)

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)

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.

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.

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.

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)

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)

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 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)

Ming Hanedanlığı'nın sonlarında ve 17. yüzyılın ortalarındaki Qig Hanedanlığı'nın başlarında yaşamış olan Şeyh Wang Daiyu, Çinli Muhammed b. Abdullah b. Elias'tan sonra Çin'deki en meşhur Müslüman alimlerden biridir. Şeyh'in yaşadığı dönem, İslam'ın Çin'de yükselişe geçtiği bir döneme karşılık gelmektedir. Bu dönemde Şeyh Wang Daiyu; bilimsel makaleler ve kitaplar yazmaya başlamış, Kur'ân-ı Kerim ve Hz. Peygamber’in sünnetindeki İslami fikirleri açıklamak için bazı Konfüçyüsçü terimler almış ve Konfüçyüsçü fikirleri İslami fikirlerle uzlaştırmaya çalışmıştır. Aynı zamanda İslam'a davet, İslam kültürünü yayma ve İslami yükseliş (...) hakkında sistematik fikirler ortaya koyma vazifesini üstlenmiştir. Bu makale temel olarak Şeyh'in biyografisine, tarihsel arka planına ve Çin medeniyeti ile İslam medeniyetinin nasıl uzlaştırılacağına dair analitik bir araştırmaya odaklanmaktadır. Nitekim onun döneminde İslam büyük bir gelişme ve canlılık kazanmıştır. Buradan hareketle Şeyh Wang Daiyu'nun İslam kültürü ile Çin kültürünün etkileşimine büyük katkı sağladığını söyleyebiliriz. Bu makale, -dünyanın Çin’i (ve Çin’li Müslüman âlimleri) daha iyi tanıması maksadıyla- “Çin hikayelerini iyi anlatın” milli sloganını gerçekleştirmeyi amaçlamaktadır.

Araştırmada; Şeyh Wang Daiyu’nun hayatı, eserleri, İslâm’ın onun dönemindeki özellikleri ve Şeyh’in, Çin medeniyeti ile İslam medeniyetini nasıl uzlaştırdığı gibi hususlar ele alınacaktır. (shrink)

Fasting of women on the days of her menstruation period is an issue that takes place in current fiqh discussions. Some contemporary researchers say that there is no religious obstacle for women to fast during these times. Moreover, they state that there is no reason to interrupt fasting, on the contrary, claim obliged to fasting. Meanwhile in traditional fiqh, it is stated that is religiously forbidden for women to fast during this period, rather it is claimed that fasting in this (...) period is ḥaram. The evidence brought to the views of all the mujtahids, who expressed their opinions on this matter was a narration from ʿĀʾisha Bint Abī Bakr (d. 58/678), a wife of Prophet (p.b.u.h). When a woman asked her if she should have fulfilled her ṣalāt (prayer) later, which she could not perform while she was in menstruation period, she responded to her as “are you Ḥarūrī?” then explained the answer. In some variants of this narration, matter of fasting is included in the question or answer. In this article, the issue of women's fasting during menstruation is discussed from a perspective based on isnād-matn analysis in the context of this narration which is called the “Ḥarūrī Ḥadīth”. In the matn of 71 riwāya identified on this article, it has been determined that the issue of fasting was added to the matns narrated by Ma'mer bin Rās̲h̲id and to some other narrations which in their corroborative (mutābī) matns not includes fasting. In later times, the version of the text with the mention of fasting was accepted as the original and became the proof that fasting of the menstruating woman was forbidden by religion. Considering the hadiths, which do not include issue of fasting, it is seen that the woman tābiʿī (Successor of the Companions) named Muâze asked ʿĀʾisha what the sunnah was about menstruating woman’s ṣalāt. Because in that era a sect called K̲h̲ārid̲j̲ites had claimed that women had to fulfill the ṣalāt that they could not perform during their menstruation, later. There are also other narrations mention the fasting of the menstruating woman. All these narrations indicated that the Prophet did not forbid fasting when menstruating, on the contrary, he just pointed out that fasting was interrupted due to menstruation. As fasting is not a worship like ṣalāt from which the woman is exempted from, a woman may interrupt fasting but must unconditionally fulfill this worship later. Thus, the situation of a woman in such a situation is equaled to the sufferer and the travelers who have a break from fasting. It is stated in traditional fiqh that a menstruating woman will not have to perform ṣalāts later that she couldn't fulfill in time. The necessity of performing a worship must be determined by a clear order of the prophet. However, a clear order regarding the prohibition of fasting during menstruation was not sought. Consequently, it is seen that the narrations are more clear evidence of the absence of any prohibition than they reveal the prohibition of fasting. It has been emphasized in the narratives that it is permissible for a woman to postpone her fast, but she is absolutely obliged to compensate the fasts that she did not fulfill, and she is not exempt from fasting as she is exempt from ṣalāt.

Ethical dilemmas are inescapable components of business negotiations. It is thus important for negotiators to understand the differences in what is ethically appropriate and what is not. This study explores the cross-cultural differences in business ethics between Canada and China by examining the perceived appropriateness of five categories of ethically questionable strategies often used in business negotiations. The results show that the Chinese are more likely to consider it appropriate to use ethically inappropriate negotiation strategies, but the impact of cultural (...) values on ethically inappropriate negotiation strategies is much stronger in Canada than in China when negotiators choose to use these strategies. In addition, there are more gender differences in Canada, where men are more likely to consider it appropriate to use ethically questionable strategies in all five categories than women; while in China no gender differences are found in the perceived appropriateness of using these strategies in all but one category. Implications are also discussed along with potential future research directions. (shrink)

This article investigates Charles Peirce’s development of logical calculi for classical propositional logic in 1880–1896. Peirce’s 1880 work on the algebra of logic resulted in a successful calculus for Boolean algebra. This calculus, denoted byPC, is here presented as a sequent calculus and not as a natural deduction system. It is shown that Peirce’s aim was to presentPCas a sequent calculus. The law of distributivity, which Peirce states in 1880, is proved using Peirce’s Rule, which is a residuation, inPC. The (...) transitional systems of the algebra of the copula that Peirce develops since 1880 paved the way to the 1896 graphical system of the alpha graphs. It is shown how the rules of the alpha system reinterpret Boolean algebras, answering Peirce’s statement that logical graphs supply a new system of fundamental assumptions to logical algebra. A proof-theoretic analysis is given for the connection betweenPCand the alpha system. (shrink)

Offers the first focused study of the shifei debates of the Warring States period in ancient China and challenges the imposition of Western conceptual categories onto these debates. In recent decades, a growing concern in studies in Chinese intellectual history is that Chinese classics have been forced into systems of classification prevalent in Western philosophy and thus imperceptibly transformed into examples that echo Western philosophy. Lin Ma and Jaap van Brakel offer a methodology to counter this approach, and illustrate their (...) method by carrying out a transcultural inquiry into the complexities involved in understanding shi and fei and their cognate phrases in the Warring States texts, the Zhuangzi in particular. The authors discuss important features of Zhuangzi’s stance with regard to language-meaning, knowledge-doubt, questioning, equalizing, and his well-known deconstruction of the discourse in ancient China on shifei. Ma and van Brakel suggest that shi and fei apply to both descriptive and prescriptive languages and do not presuppose any fact/value dichotomy, and thus cannot be translated as either true/false or right/wrong. Instead, shi and feican be grasped in terms of a pre-philosophical notion of fitting. Ma and van Brakel also highlight Zhuangzi’s idea of “walking-two-roads” as the most significant component of his stance. In addition, they argue that all of Zhuangzi’s positive recommendations are presented in a language whose meaning is not fixed and that every stance he is committed to remains subject to fundamental questioning as a way of life.

Integrating stakeholder agency theory with the instrumental corporate social responsibility (CSR) literature, this study explores how award-winning CEOs consider personal interests and balance competing stakeholder demands when they decide between external and internal CSR, or CSR focus. Using a difference-in-differences research design, we find that after winning a prestigious media award, CEOs engage in more external CSR, which is more visible to the public, and less internal CSR, which is less likely to attract public attention. We find that such an (...) influence on CSR focus is more salient for award-winning CEOs with lower stock ownership (i.e. a stronger self-serving motivation) than for CEOs with higher stock ownership. Furthermore, we explore the role of stakeholder salience in modifying award-winning CEOs’ decisions about CSR focus. When external stakeholder salience is higher (e.g. higher media coverage), award-winning CEOs' manipulation of CSR focus by increasing external CSR and decreasing internal CSR is more salient. However, such effects can be dampened when internal stakeholder salience is higher (e.g. higher human capital intensity). Our study contributes to the instrumental CSR literature by demonstrating the underlying processes and boundary conditions of how awards affect CEOs' balance of stakeholder salience. (shrink)

We argue that all general concepts are family resemblance concepts. These include concepts introduced by ostension, such as colour(s). Concepts of colour and of each of the specific colours are family resemblance concepts because similarities concerning an open‐ended range of colour or of appearance features crop up and disappear. After discussing the notion of “same colour” and Wittgenstein's use of the phrase “our colours”, we suggest family resemblance concepts in one tradition can often be extended to family resemblance concepts in (...) another tradition, illustrated by Wittgenstein's use of the words Spiel and “game”.
