We study a joint pricing and inventory control problem for perishables with positive lead time in a finite horizon periodic-review system. Unlike most studies considering a continuous density function of demand, in our paper the customer demand depends on the price of current period and arrives according to a homogeneous Poisson process. We consider both backlogging and lost-sales cases, and our goal is to find a simultaneously ordering and pricing policy to maximize the expected discounted profit over the planning horizon. (...) When there is no fixed ordering cost involved, we design a deep reinforcement learning algorithm to obtain a near-optimal ordering policy and show that there are some monotonicity properties in the learned policy. We also show that our deep reinforcement learning algorithm achieves a better performance than tabular-based Q-learning algorithms. When a fixed ordering cost is involved, we show that our deep reinforcement learning algorithm is effective and efficient, under which the problem of “curse of dimension” is circumvented. (shrink)

GraphicalPatients with early- to middle-stage PD were enrolled for C-Gait assessment and traditional walking ability assessments. The correlation of C-Gait assessment and traditional walking tests were studied. Two models were established based on C-Gait assessment and traditional walking tests to explore the value of C-Gait assessment in predicting freezing of gait.ObjectiveEfficient methods for assessing walking adaptability in individuals with Parkinson’s disease are urgently needed. Therefore, this study aimed to assess C-Gait for detecting freezing of gait in patients with early- to (...) middle-stage PD.MethodPeople with PD diagnosis were recruited from April 2019 to November 2019 in Beijing Rehabilitation Hospital. The participants performed six items of walking adaptability on an instrumented treadmill augmented with visual targets and obstacles. The patient’s walking adaptability was evaluated by C-Gait assessment and traditional walking tests, and FOG-related indexes were collected as outcome measures. Two discriminant models were established by stepwise discriminant analysis; area under the receiver operating characteristic curve was used to validate the models.ResultIn total, 53 patients were included in this study. Most C-Gait assessment items had no or low correlations with traditional walking tests. The obstacle avoidance and speed of adaptation items could lead to FOG with high sensitivity. In addition, the C-Gait assessment model had slightly better discrimination of freezers from non-freezers compared with traditional walking test models ; specifically, obstacle avoidance and speed of adaptation have uniquely discriminant potential.ConclusionC-gait assessment could provide additional value to the traditional walking tests for PD. Gait adaptability assessment, as measured by C-Gait, may be able to help identify freezers in a PD population. (shrink)

To identify the boundary conditions for proactive employees making whistle-blowing decisions, we developed a cross-level model comprising employee proactive personality and two types of whistle-blowing intentions that incorporates the influences of organizational- and individual-level attributes. Analyses of data collected from 432 Chinese employees in 32 companies indicated that proactive personality was positively related to internal whistle-blowing intention and even more positively related to external whistle-blowing intention when individuals were working in organizations characterized by an instrumental ethical climate and employees with (...) a high level of moral identity.

ObjectiveTo confirm the effects of a transtheoretical model based on multidimensional life management on healthy behavior in patients with polycystic ovary syndrome.MethodsIn total, eighty eligible patients were recruited from March 2021 to June 2021 and randomly assigned to either the intervention or control groups. Outcome measures include health-promoting behavior, self-efficacy, anthropometrics, and the number of unplanned outpatient admissions. Data were collected at baseline, 3, and 6 months after the intervention. The chi-square test, rank-sum test, t-test, and repeated measurement analysis of (...) variance were used to analyze the data.ResultsIn total, sixty-six participants completed the study: 35 participants in the intervention group and 31 participants in the control group. After 6 months of intervention, the healthy behavior level of patients with PCOS increased from moderate [health-promoting lifestyle profile -II score of 105.37 ± 12.57] to good in the intervention group; and there was no change observed in the control group. In addition, the total self-efficacy score, PCOS-related unplanned outpatient admissions, waist circumference, and body mass index were found to have a significant difference in the intervention group at 6 months. Meanwhile, repeated measures analysis of variance showed a significantly greater improvement in health-promoting behavior and self-efficacy over time in the intervention group than in the control group.ConclusionThe transtheoretical model based on multidimensional life management positively affected healthy behavior, self-efficacy, the number of unplanned outpatient admissions, and anthropometrics in patients with PCOS.Clinical Trial Registrationwww.chictr.org.cn, ChiCTR2000034572.

According to Marxist philosophy, everything in the world is universally connected and in perpetual motion. Chinese society has gone through a long history of civilizational development. Since the modern era (1840-1919), great changes have taken place in the civilizational development of China. The transformation of social forms depends on the transformation of culture, and the approximation of culture to modernity is a prerequisite for the modernization of society. Thus, the development of society inevitably causes changes in art and culture; and (...) vice versa, the progress of art and culture, in turn, contributes to the progress of society. A clear and complex line has been traced in the development of Chinese painting over the centuries: from a high degree of integration to gradual differentiation leading to conflict, and then to integration. The development of Chinese painting as a whole shows a transformational trend from tradition to modernity, developing in a tortuous way. In this paper, a combination of research methods is used for research, mainly documentary research, descriptive research, comparative research and case study. Considering the features and trends of Chinese painting at different stages of development, we can more accurately judge the direction of development of modern Chinese painting and find ways to integrate tradition and modernity.

Chinese painting has always been a unique product of our ancient civilization, which has survived to the present day. During its 2000-year development, Chinese painting has gradually turned into a unique and non-reproducible art form capable of expressing the thoughts and feelings of the artist. Over time, Chinese painting also demonstrates a new trend of inheritance and innovative development. Changes in Chinese painting occur simultaneously with the processes of globalization. This gives rise to new research on the trends of diversification (...) of artistic creativity. The focus of artistic expression has shifted from the depiction of direct natural objects towards the spiritual plane, which is a direct result of the creative activity of artists whose aspirations are manifested in the use of traditional Chinese ink painting in combination with new methods of figurative representation and deep understanding of spiritual content. Since ancient times, artists have actively sought to harmonize and balance the subjective and objective, as well as to achieve their organic combination. This article examines traditional Chinese painting as a source and driving force of the transformation of Chinese painting、prints of the era and integration in the content of paintings、attempts to introduce the Western concept of frontal composition, as well as updating the language of painting and artistic concepts. It is argued that the fundamental driving force and the main support for the development of Chinese painting in the context of globalization should be traditions integrated with new creative elements and techniques, thus it is possible to better promote Chinese culture and inherit the essence of traditional Chinese painting.

Background An increasing number of studies on physicians’ professionalism have been done since the 2002 publication of Medical Professionalism in the New Millennium: A Physician Charter. The Charter proposed three fundamental principles and ten responsibilities. However, most studies were done in developed countries, and few have been done in China. Additionally, few studies have examined the effect of patient-centered hospital culture (PCHC) on physicians’ professionalism. We aimed to investigate physicians’ medical professionalism in public hospitals in China, and to assess mediating (...) effect of professional attitudes in the relationship of PCHC with professional behaviours. Methods Self-administered questionnaires including professional attitudes (20 items) and behaviours (10 items) survey and PCHC scale (22 items) were given to clinical physicians in five public hospitals, China. The mediating effect of professional attitudes in the relationship of PCHC with professional behaviours was tested. Result 232 valid questionnaires were collected. More than 90% (208) respondents agreed with 15 of 20 specific statements on medical professionalism. As for the responsibility of improving quality of care, 54 (23%) respondents disagreed with reporting of incompetent colleagues and as for the responsibility of maintaining professional competence, 49 (21%) disagreed with recertification. More than 185 (83%) respondents reported that they sometimes, usually, or always showed the four positive behaviours on the questionnaire, and 173 (77%) reported that they never showed the six negative behaviours. Mediating effect analysis revealed that two dimensions of PCHC (i.e. value/institution culture and behaviour/material culture) had a significant positive impact on physicians’ professional behaviour, and professional attitude played a complete mediation role between them, but another dimension of PCHC (i.e. negative evaluation of hospital) directly affected professional behaviour without influencing professional attitude. Conclusion Chinese physicians showed positive professional attitudes and behaviours. Different dimensions of PCHC affected physicians’ attitudes and behaviours in different ways. (shrink)

Public health emergencies can trigger individual death anxiety. Most previous studies focus on the negative effects of death anxiety via the Western materialistic view, neglecting both the positive aspects of death anxiety within the Chinese cultural background and the positive effects of death anxiety upon environmental consumption. By implementing the unique Chinese cultural background for the concepts of justice and interests, this study explores the positive influence of individual death anxiety on altruistic environmental consumption during the COVID-19 crisis by analyzing (...) personal life reviews and other sources. The results show that under the guidance of the correct concept of justice and benefit, individuals with high death anxiety during the epidemic period not only enhance their self-esteem through positive self-perception and social evaluation, but they are more inclined to benefit from other environmental consumption behaviors and attain a symbolic self-survival; and during the epidemic period, mental resilience, as a transformation mechanism of external defense and the internal growth of death psychology, can directly affect altruistic environmental consumption by consumers without relying on external standards. In the context of the Chinese culture’s concept of justice and interests, this study enriches the knowledge of fear management theory and the positive impact of death anxiety on environmental consumption. The introduction of mental resilience as a boundary condition has important theoretical and practical significance within the study of consumer behavior in public health emergencies and post-epidemic economic recovery.

As more organizations adopt telecommuting or working from home, the work-connected behavior of their employees during non-working hours increases, weakening the boundary between work and family. However, no study has clearly identified whether and how work connectivity behavior after-hours affects employees’ work and family status. Therefore, using role theory, we explored the mechanisms by which WCBA affects employees’ thriving at work and family through work–family enrichment and work–family conflict, and compared the impact of different levels of support for family members (...) on work–family enrichment and conflict, using the Johnson–Neyman method. Our analysis of two-wave data from 257 employees led to the following findings. WCBA had a positive impact on thriving at work, but not on family. There is a ‘double-edged sword’ effect on the impact of WCBA on thriving at work, meaning that work–family enrichment can positively influence thriving at work and negatively influence work–family conflict. There is a double-edged sword effect on the impact of WCBA on thriving at family, meaning that work–family enrichment can positively influence thriving at family and negatively influence work–family conflict. The support of family members moderates the double-edged sword effect between WCBA and thriving at work, in that it can strengthen the positive effects of work–family enrichment and weaken the negative effects of work–family conflicts. Support from family members reinforces the positive impact of work–family enrichment on thriving at family. Thus our study reveals the mechanisms by which WCBA affects the thriving at work and family of employees, and identifies potential methods for managing different levels of work–family enrichment and work–family conflict from the perspective of family member support.

Compare with other professions, teachers are reported to have a higher risk of poor mental health. This study examined the relationships between emotional intelligence, perceived organizational justice, and mental health among Chinese high school teachers. Three hundred and eighty-one high school teachers, with their age range between 21 and 50 years, were administered the Emotional Intelligence Scale, Perceived Organizational Justice Scale, and Mental Health Scale. The result found that emotional intelligence and perceived organizational justice directly influence the mental health of (...) high school teachers. In addition, perceived organizational justice mediated the association between emotional intelligence and mental health. Moreover, the present study analyzes the different role of subtypes of perceived organizational justice on the relationships between emotional intelligence and mental health, and the results showed that the mediating effects of perceived distributive justice and interactive justice on emotional intelligence and mental health are not significant, only the perceived procedural justice mediated the relationships between emotional intelligence and teachers’ mental health. The results are discussed in a conceptual context. (shrink)

This study aims to create a research model that examines how employee agility is affected by enterprise social media usage, and to discuss the moderating role of innovation culture in communication quality, trust, and employee agility using the relational capital theory. Data of 477 Chinese employees from different companies were collected in this study for analysis, and the hypotheses developed were examined. The purpose of this study was to explore the influence mechanism that propels employees’ ESMU, communication quality and trust (...) and the moderating effect of innovation culture. This study conducts PLS-SEM to analyze collected data. The results show that ESMU is positively associated with communication quality and trust; innovation culture plays a positive moderating role in ESMU and employee agility; and high communication quality and trust can lead to high agility. However, innovation culture does not have a remarkable moderating effect on ESMU and communication quality. This study offers empirical evidence on how the effect of ESMU on employee agility is transferred by innovation culture. In addition, the benefits of enterprise social media for organizational management are also measured in this study, which may motivate the managements to introduce enterprise social media in work spaces.

The massive social change in urban China today has led to a decline in the adaptive implications of shyness for child adjustment, yet evidence of this trend in young children is limited. Moreover, the underlying mechanisms that help to explain the associations between shyness and maladjustment remains poorly understood. The primary goal of the present study was to explore the moderating role of conflict resolution skills in the links between shyness and socio-emotional and school adjustment among urban Chinese preschoolers. Data (...) were collected from 360 children in kindergartens using parent ratings, teacher ratings, and child interviews. The analyses indicated that the relations between shyness and adjustment were moderated by child conflict resolution skills, which served to buffer shy children from adjustment problems. The results were discussed in terms of the implications of conflict resolution skills for early adjustment of shy preschoolers in the Chinese context. (shrink)

The energy hole is a severe problem for underwater acoustic distributed networks in that it affects the normal operations of the network and shortens the network’s life span. To deal with this problem, a loop-free routing control technique is proposed in this paper. The classical shortest-path routing control method is used to generate multiple disjointed routing tables. The residual energy of the nodes and the changing information of the uplink/downlink matrix are added to the data frames for distribution. The source (...) node specifies the routing path to transmit the data frames based on the changing information, and the relay nodes route the data frames strictly according to the routing path designated by the source node. Besides, the energy consumption of the relay node is saved by replying to the pseudo-ACK frame. Simulation experiments are implemented in four typical scenarios, and the results reflect that the proposed technique could extend the network’s life span by approximately 10% when compared to other mature techniques. Besides, it has no other negative effects on the normal operations of the network. (shrink)

Completa y exhaustiva monografía sobre la obra y el pensamiento de Edgar Morin desde la perspectiva de sus planteamientos antropológicos, relacionando éstos con algunos de los debates antropológicos actuales más relevantes.

This article engages with the historiography of the Portuguese empire with reference to Mozambique. It explores the impact of visual archives on existing debates and asks what difference photographs make to our interpretation and understanding of this colonial past. Deprived of their 'historical rights' by the requirements of the Berlin treaties that insisted on 'effective occupation', the Portuguese started to employ a complex of knowledge-producing activities in which photography was crucially involved. This article examines different photographic moments before and during (...) the 'Pacification Campaign' that assured Portugal's authority over the Gaza Empire in southern Mozambique in the 1890s, by official, commercial and missionary photographers. It identifies controversies over the small number of portraits of the Gaza king Ngungunyane that took on distinctive and disputed 'other lives' after their initial production. The realisation of how one image might be disassembled to generate others becomes an exercise - in visual terms - of rethinking colonial violence. A critical engagement with the slippages and repositionings around photographs, and the errors or disputes in various captions, allows for a better understanding of the production of both silence and particular narratives in the archives and popular history. The demonstration of these other lives matters because it stimulates awareness of what is seen, what is made visible, and addresses the desire to look beyond the image to find others in a continuous interrogation of photographic excess.

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question remains controversial (...) in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

For many energy companies in China, green brand strategy is becoming an important approach to enhance competitive advantage. However, greenwashing behaviors result in a crisis of trust. Existing research focuses on green marketing, but is silent on the institutional view of the trust crisis resulting from greenwashing by energy brands. Thus, this study takes a decoupling perspective from institutional theory and considers legitimacy, energy policy management, and green brand theories to shed light on the path from the decoupling of an (...) energy brand from green promise to green energy brand trust and the role of brand legitimacy and brand loyalty. It then analyzes survey data to conclude that DEBG not only has a direct negative effect on GEBT but also has an indirect influence through the vital mediating role of green energy brand legitimacy. Moreover, brand loyalty is a moderating factor and can alleviate the energy brand trust crisis. These findings not only can enrich the theories of energy brand management and green marketing but also offer important implications for energy policy management. (shrink)

This paper addresses a phenomenon in which certain word-parts can be omitted. The evidence shows that the full range of data cannot be captured by a sublexical analysis, since the phenomena can be observed both in phrasal and in lexical environments. It is argued that a form of deletion is involved, and that the phenomena—lexical or otherwise—are subject to the same phonological, semantic, and syntactic constraints. In the formalization that is proposed, all of the above constraints are cast in a (...) parallel and declarative fashion, in the framework of Head-Driven Phrase Structure Grammar (Pollard and Sag Head-driven phrase structure grammar, 1994), since the various levels of linguistic description are locally and simultaneously available. Building on recent accounts of ellipsis, this paper proposes a unified and general account of word-part ellipsis and phrasal ellipsis. (shrink)

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic (...) numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing. (shrink)

This article is a Gadamer-Perelman's debate. The author points out the limits of the gadamerian's hermeneutic conception of philosophy and criticizes this conception from Perelman's new rhetoric point of view. Instead of speaking of truth as an ontological originary experience, the rhetorical foundation of philosophy allows us to say that in philosophy the important is the contrastation and the confrontation of criteria and that, for that reason, philosophy is above all characterized by discussibility.

Although many consider professional ethics in the food supply chain an essential topic that should be covered in any degree program, few higher education institutions currently include a module on ethics in their study programs. Instead, ethics is taught in tandem to the core curriculum and is often embedded in the contents of other modules rather than treated as a subject in its own right. Ethics, however, is important enough to warrant a different teaching and educational approach. This book provides (...) support for development of a course in ethics for food studies education. The book is divided into 3 sections, each containing several chapters: Section 1 includes chapters that identify and discuss several ethical issues along the food chain, with particular attention given to issues in the food industry and in consumer behavior; Section 2 includes chapters that present the basis of a code of conduct in the food profession, as well as descriptions of existing codes of conduct for food industry and food scientist professionals. These include codes for the ethics of publishing, and also ethics in risk communication; Section 3 includes chapters based on case studies with examples of teaching approaches currently used in teaching food ethics. These approaches are easy to implement and have already been tested and confirmed as successful examples that engage students in this topic. (shrink)
