Water saving irrigation is promoted as a strategy to mitigate future water stresses by the Chinese government and irrigation scientists. However, the dissemination of WSI in China has been slow and little is understood with respect to why farmers adopt WSI or how WSI interacts with the social and institutional contexts in which it is embedded. By analyzing qualitative data from 37 semi-structured and 56 unstructured interviews across 13 villages in northwest China, this paper examines smallholder farmers’ knowledge and perceptions (...) of WSI, and how WSI interacts with farmer livelihood decision-making and extant systems of land and water management. The results show that smallholders’ willingness to adopt and continuously use WSI was dampened by a lack of communal capital and measures for conflict resolution, a disconnect between the temporal demands of practicing WSI and the ways farmers prioritize different livelihood strategies, misconceptions about WSI systems and how they work, market risks, and landownership structure and economies of scale. These results suggest that programs for promoting WSI must be holistic in nature and address smallholders’ day-to-day problems. Understanding why WSI did not succeed in some places will help formulate policy interventions that avoid reproducing conflicts, risks, and technological malfunctions responsible for previous failure.

Noise in behavior is often viewed as a nuisance: while the mind aims to take the best possible action, it is let down by unreliability in the sensory and response systems. How researchers study cognition reflects this viewpoint – averaging over trials and participants to discover the deterministic relationships between experimental manipulations and their behavioral consequences, with noise represented as additive, often Gaussian, and independent. Yet a careful look at behavioral noise reveals rich structure that defies easy explanation. First, both (...) perceptual and preferential judgments show that sensory and response noise may potentially only play minor roles, with most noise arising in the cognitive computations. Second, the functional form of the noise is both non-Gaussian and non-independent, with the distribution of noise being better characterized as heavy-tailed and as having substantial long-range autocorrelations. It is possible that this structure results from brains that are, for some reason, bedeviled by a fundamental design flaw, albeit one with intriguingly distinctive characteristics. Alternatively, noise might not be a bug but a feature: indeed, we suggest that noise is fundamental to how cognition works. Specifically, we propose that the brain approximates probabilistic inference with a local sampling algorithm, one that uses randomness to drive its exploration of alternative hypotheses. Reframing cognition in this way explains the rich structure of noise and leads to a surprising conclusion: that noise is not a symptom of cognitive malfunction but plays a central role in underpinning human intelligence.

Previous research has indicated that parenting factors affect the risk of maladaptive psychological outcomes, and that positive parenting is a prospective risk factor for maladaptive psychological outcomes. However, the mechanisms underlying the relationships between positive parenting, mindfulness, and maladaptive psychological outcomes remain unknown, as do the processes that mediate the effect of positive parenting on maladaptive psychological outcomes in adolescents. The objective of the present study was to investigate the longitudinal relationship between positive parenting, mindfulness, and maladaptive psychological outcomes in (...) middle school students, as well as the mediating effect of mindfulness in the relationships between positive parenting and depression, aggression, and suicidal ideation. In this study, 386 middle school children were tested three times over a period of 6 months. Positive parenting was assessed at Time 1, mindfulness at Time 2, and depression, aggression, and suicidal ideation at Time 3. Using structural equation modeling, positive parenting was revealed to be longitudinally associated with mindfulness and negatively associated with maladaptive psychological outcomes. More crucially, mindfulness mediated the relationship between positive parenting and maladaptive psychological outcomes. This research provides important insights into how to effectively decrease adolescent maladaptive psychological outcomes and highlights the importance of teaching mindfulness to youths. (shrink)

This study aims to explore the current situation and strategy formulation of sports psychology teaching in colleges and universities following adaptive learning and deep learning under information education. The informatization in physical education, teaching methods, and teaching processes make psychological education more scientific and efficient. First, the relevant theories of adaptive learning and deep learning are introduced, and an adaptive learning analysis model is implemented. Second, based on the deep learning automatic encoder, college students’ sports psychology is investigated and the (...) test results are predicted. Finally, the current situation and development strategy of physical education in colleges and universities are analyzed. The results show that when the learning rate is 1, 0.1, and 0.01, there is no significant change in the analysis factors of recall, ndcg, item_coverage, and sps. When the learning rate is 1, their analysis factors change obviously, and it is calculated that the optimal learning rate of the model is 1. And the difficulty of the recommended test questions by using the sports psychology teaching method based on adaptive learning and deep learning is relatively stable. The test questions include various language points of sports psychology. Compared with others methods, adaptive learning and deep learning can provide comprehensive test questions for sports psychology teaching. This study provides technical support for the reform of sports psychology teaching in colleges and universities and contributes to optimizing the information-based teaching mode. (shrink)

People are adept at perceiving interactions from movements of simple shapes, but the underlying mechanism remains unknown. Previous studies have often used object movements defined by experimenters. The present study used aerial videos recorded by drones in a real-life environment to generate decontextualized motion stimuli. Motion trajectories of displayed elements were the only visual input. We measured human judgments of interactiveness between two moving elements and the dynamic change in such judgments over time. A hierarchical model was developed to account (...) for human performance in this task. The model represents interactivity using latent variables and learns the distribution of critical movement features that signal potential interactivity. The model provides a good fit to human judgments and can also be generalized to the original Heider–Simmel animations. The model can also synthesize decontextualized animations with a controlled degree of interactiveness, providing a viable tool for studying animacy and social perception. (shrink)

Art and philosophy are the two major elements of the human world. The existence of art and philosophy can expand the spiritual world of human beings to a greater extent and enrich their spiritual life, thus supporting the construction of the material world. And music, as an aural art, has also been given a philosophical meaning in the evolution of history because of its birth and development. Therefore, when studying music, one should first study the history of music. The philosophy (...) of music history education is not only profound and contains world culture and philosophy, but also carries history and economy. Music history education is also a vivid art form of philosophy, where teachers create an artistic beauty to attract students and achieve the purpose of imparting knowledge by optimizing their educational philosophy. To develop the philosophy of education to its fullest extent, teachers must adhere to the concepts associated with the philosophy of art. To explain this process in greater depth, this paper provides a brief review of the aesthetic philosophy and historical evolution of Chinese. (shrink)

Social networks have become an important way for users to find friends and expand their social circle. Social networks can improve users’ experience by recommending more suitable friends to them. The key lies in improving the accuracy of link prediction, which is also the main research issue of this study. In the study of personality traits, some scholars have proved that personality can be used to predict users’ behavior in social networks. Based on these studies, this study aims to improve (...) the accuracy of link prediction in directed social networks. Considering the integration of personality link preference and asymmetric interaction into the link prediction model of social networks, a four-dimensional link prediction model is proposed. Through comparative experiments, it is proved that the four-dimensional social relationship prediction model proposed in this study is more accurate than the model only based on similarity. At the same time, it is also verified that the matching degree of personality link preference and asymmetric interaction intensity in the model can help improve the accuracy of link prediction.

Airway mucin secretion is important pathophysiologically and as a model of polarized epithelial regulated exocytosis. We find the trafficking protein, SNAP23, selectively expressed in secretory cells compared with ciliated and basal cells of airway epithelium by immunohistochemistry and FACS, suggesting that SNAP23 functions in regulated but not constitutive epithelial secretion. Heterozygous SNAP23 deletant mutant mice show spontaneous accumulation of intracellular mucin, indicating a defect in baseline secretion. However mucins are released from perfused tracheas of mutant and wild-type mice at the (...) same rate, suggesting that increased intracellular stores balance reduced release efficiency to yield a fully compensated baseline steady state. In contrast, acute stimulated release of intracellular mucin from mutant mice is impaired whether measured by a static imaging assay 5 min after exposure to the secretagogue ATP or by kinetic analysis of mucins released from perfused tracheas during the first 10 min of ATP exposure. Together, these data indicate that increased intracellular stores cannot fully compensate for the defect in release efficiency during intense stimulation. The lungs of mutant mice develop normally and clear bacteria and instilled polystyrene beads comparable to WT mice, consistent with these functions depending on baseline secretion that is fully compensated.

The popularization of intelligent machines such as service robot and industrial robot will make human–machine interaction, an essential work mode. This requires employees to adapt to the new work content through learning. However, the research involved human–machine interaction that how influences the employee’s learning is still rarely. This paper was to reveal the relationship between human–machine interaction and employee’s learning from the perspective of job characteristics and competence perception of employees. We sent questionnaire to 500 employees from 100 artificial intelligence (...) companies in China and received 319 valid and complete responses. Then, we adopted a hierarchical regression for the test. Empirical results show that human–machine interaction has a U-shaped curvilinear relationship with employee learning, and employee’s vitality mediates the curvilinear relationship. In addition, job characteristics moderate the U-shaped curvilinear relationship between human–machine interaction and employee’s vitality, especially the results of moderating effects varying with employee’s competence perception. Exploring the mechanism of the effect of human–machine interaction on employee’s learning enriches the socially embedded model. Moreover, it provides managerial implications how to enhance individual adaptability with the introduction of AI into firms. However, our research focuses more on the impact of human–machine interaction on employees at the initial stage of AI development, and the level of machine intelligence in various industries will reach a high degree of autonomy in the future. The future research can explore the impact of human–machine interaction on individual’s behavior at different stages, and the results may vary depending on the technologies mastered by different individuals. The study has theoretical and practical significance to human–machine interaction literature by underscoring the important of individual’s behavior among individuals with different skills. (shrink)

Remanufacturing widely exists in production activities. Two different game models are involved while considering reverse channels: In Model P, the manufacturer provides new and remanufactured products to two retailers. New products are sold through an online platform, while remanufactured products are sold in offline physical stores in a decentralized scenario. In Model C, the manufacturer provides new and remanufactured units to only one retailer that operates both online and offline channels in a centralized scenario. This research showed that a manufacturer’s (...) profitability and industry profits in Model P were higher than those in Model C from the perspective of economic performance; the sum of the profits of both retailers in Model P was worse than the profits of the retailer in Model C. Moreover, Model P was found to be greener than Model C from the perspective of environmental sustainability. From a social viewpoint, Model P had a higher consumer surplus than Model C; the higher the cost of distributing a remanufactured unit, the more disadvantageous the model to the consumers. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.1 (2002) 1-17 [Access article in PDF] What if the Father Commits a Crime? Rui Zhu Apparently, Socrates and Confucius respond similarly to the question if a son should turn in his father in the case of the father's misdemeanor. When Euthyphro, flaring his pride of his moral impartiality, tells Socrates that he is on his way to report his father because he (...) has thrown one of the household slaves into a ditch and left him bound there until he was dead, Socrates says, "Good Heaven! Certainly, Euthyphro, most men would not know how they could do this and be right. It is not the part of anyone to do this, but of one who is far advanced in wisdom." 1According to Socrates, only a man of high wisdom knows how to prosecute his father righteously, but Euthyphro does not appear to have this wisdom. When his interlocutor observes that an upright man in his state would bear witness against his father if he misappropriates a sheep, Confucius contradicts the interlocutor's understanding of uprightness by speaking in a matter-of-fact tone: "In my country the upright men are of quite another sort. A father will cover up for his son, and a son his father—which incidentally does involve a sort of up—rightness." 2Confucius stands on the same line with Socrates but seems the more radical of the two. Socrates does not directly refute Euthyphro and only suggests that he make sure he understands what he is doing before going any further. Socrates is not only typically Socratic—indirect and suggestive—but also sounds so reasonable that Euthyphro appears in contrast to be a reckless youth who harbors [End Page 1] only a faint understanding of morality. Confucius's response is more rigid, for he categorically dismisses an act of the Euthyphroian kind. He demands that father and son cover up for each other in the case of either one's guilt. Compared to Socrates, Confucius advocates the position that seems a little too strong and leaves no room for justice, while Socrates does not have that problem with justice. This is how we feel about Socrates and Confucius on our first impression. The prima facie observations that we make from the remarks of Socrates and Confucius seem both plain and unproblematic.By embedding these remarks into their respective social or philosophical cultures, this paper will show that our previous observations are not quite accurate. The apparent affinity of the Socratic and Confucian stances belies different underlying moral philosophies. We want to use their comments as bridges to explore the early Greek and Confucian ethics and show how different a picture we see after things are examined within their traditions.The issue of a possible father-son conflict may be treated as a case study of the early Greek (the Heroic era until the age of Socrates) and early Confucian (Confucius and Mencius) morals. There is a strong theme in the early Greek morals that allows, or sometimes demands, a son such as Euthyphro to prosecute his father for the sake of justice, because justice, instead of love (philein) or filial piety, is the governing principle in the early Greek ethics. Confucian ethics is founded on love (human-heartedness), which in turn is extended from the love between father and son. All moral principles including justice are derived from this extension of love. The mutual love of father and son then becomes the governing principle in the case of Confucianism. A Guilty Father: The Greek Motif The question, "What if the father commits a crime?" has a certain realistic aroma to a boy coming of age in the Hesiodic Greek world. That father has to be overcome by son before some relief from strife becomes possible is a familiar theme in Greek literature. In Hesiod's Theogony, Uranus (the sky) incurs hatred from all his newborn children since he hides them in their mother Gaia's womb and does not let them return to the light, for no reason...

This paper begins by reviewing dominant themes in current teaching of professional ethics in engineering education. In contrast to more traditional approaches that simulate ethical practice by using ethical theories to reason through micro-level ethical dilemmas, this paper proposes a pragmatic approach to ethics that places more emphasis on the practical plausibility of ethical decision-making. In addition to the quality of ethical justification, the value of a moral action also depends on its effectiveness in solving an ethical dilemma, cultivating healthy (...) working relationships, negotiating existing organizational cultures, and achieving contextual plausibility in everyday professional practice. This paper uses a cross-cultural ethics scenario to further elaborate how a pragmatic approach can help us rethink ethical reasoning, as well as ethics instruction and assessment. This paper is expected to be of interest to educators eager to improve the ability of engineers and other professional students to effectively and appropriately deal with the kinds of everyday ethical issues they will likely face in their careers.

Photographs are commonly taken of children in medical and research contexts. With the increased availability of photographs through the internet, it is increasingly important to consider their potential for negative consequences and the nature of any consent obtained. In this research we explore the issues around photography in low-resource settings, in particular concentrating on the challenges in gaining informed consent.

ABSTRACT:In the expanding field of ethical leadership research, little attention has been paid to the association between ethical leaders’ ethical characteristics and perceived ethical leadership, and, more importantly, the potential influence of ethical leadership on followers’ ethical characteristics. In this study, we tested a theoretical model based upon social cognitive theory to examine leaders’ moral identity and moral attentiveness as antecedents of perceived ethical leadership, and follower moral identity and moral attentiveness as outcomes of ethical leadership. Based upon data from (...) 89 leaders and 460 followers in China, collected at two points in time, we found that leaders’ moral identity and moral attentiveness are associated with follower’s perceptions of ethical leadership. Ethical leadership is, in turn, associated with their followers’ moral identity and moral attentiveness. We found furthermore that ethical leadership mediates the effect of leaders’ moral identity on followers’ moral identity, but not the effect of leaders’ moral attentiveness on followers’ moral attentiveness. We discuss the findings, theoretical contributions, practical implications, and future research. (shrink)

Although previous research has examined the effectiveness of various levels of punitive reactions to misconduct, researchers have given leader leniency relatively inadequate attention. Prior studies consistently suggest the beneficial effects of reacting less punitively toward misconduct. The current research challenges this notion by delineating a mixed effect of leader leniency on subordinate psychological and behavioral reactions. Building on social exchange theory (i.e., reciprocity norm and rank equilibration norm) and motive attribution literature, the authors argue that when subordinates hold high levels (...) of instrumental motive attribution, leader leniency relates positively to subordinate psychological entitlement, which in turn leads to workplace deviance. In contrast, when subordinates develop high levels of value-expressive motive attribution, leader leniency is positively associated with their felt obligation toward leaders, which positively influences their subsequent organizational citizenship behavior. The results of a field study, a scenario experiment, and a recall experiment conducted to test these hypotheses confirm the double-edged effects of leader leniency. These findings have important implications for theory and practice. (shrink)

As one of the three systems of China's traditional culture, Daoism has an important place in the history of Chinese philosophy. Based on the ideas of inaction performing all, the Way modeling spontaneity, and the dialectic of you [having, being] and wu [lacking, nonbeing], this article is a systematic exploration of Laozi's philosophy of denial, spontaneity, and atheism, as well as of the deep and lasting influence of his metaphysical principles on all schools of traditional Chinese philosophy.

Although corporate governance researchers have devoted considerable attention to the role of boards of directors in monitoring management and providing resources, less attention has been paid to whether and how they affect the strategic actions of firms in response to changing environments. Taking a process-based perspective, we examine how several prevalent board processes affect the involvement of boards in strategic decision-making and how such involvement shapes organizational performance. Moreover, we offer an initial attempt to compare the strategic role of boards (...) in for-profit and non-profit organizations. An investigation of 217 for-profit and 156 non-profit organizations in Canada indicates that different processes lead boards to different levels of strategic involvement, and that such effects are contingent on the types of organizations concerned. Moreover, boards that are active in strategic decision-making enhance the performance of their organizations. Our findings have implications for board research and practice. (shrink)

In “Considering Causalisms”, Andrew Sneddon critically examines causalism, the dominant position in action theory since Donald Davidson published his influential article, “Actions, Reasons, and Causes”. Sneddon’s analysis is based on a distinction he makes between two kinds of causalism. One is a minimal version of causalism, which holds only a causal view of reasons explanations. Sneddon calls it “restricted-causalism,” or causalismR.
