In air traffic control, the airspace is divided into several smaller sectors for better management of air traffic and air traffic controller workload. Such sectors are usually managed by a team of two air traffic controllers: planning controller and executive controller. D-side controller is responsible for processing flight-plan information to plan and organize the flow of traffic entering the sector. R-side controller deals with ensuring safety of flights in their sector. A better understanding and predictability of D-side controller actions, for (...) a given traffic scenario, may help in automating some of its tasks and hence reduce workload. In this paper, we propose a learning model to predict D-side controller actions. The learning problem is modeled as a supervised learning problem, where the target variables are D-side controller actions and the explanatory variables are the aircraft 4D trajectory features. The model is trained on six months of ADS-B data over an en-route sector, and its generalization performance was assessed, using crossvalidation, on the same sector. Results indicate that the model for vertical maneuver actions provides highest prediction accuracy. Besides, the model for speed change and course change action provides predictability accuracy of 80% and 87%, respectively. The model to predict the set of all the actions for each flight achieves an accuracy of 70% implying for 70% of flights; D-side controller’s action can be predicted from trajectory information at sector entry position. In terms of operational validation, the proposed approach is envisioned as ATCO assisting tool, not an autonomous tool. Thus, there is always ATCO discretion element, and as more ATCO actions are collected, the models can be further trained for better accuracy. For future work, we will consider expanding the feature set by including parameters such as weather and wind. Moreover, human in the loop simulation will be performed to measure the effectiveness of the proposed approach. (shrink)

Philosophy in Vietnam is defined as a system of the most universal points of view on the world and the place of man in this world. Philosophy often plays a key role it plays in one’s worldview and methodology. The question is: on what problems should philosophy focus in order to successfully carry out its worldview andmethodological role in the present context? Firstly, if international philosophers are focusing their research on problems caused by globalization, Vietnamese philosophers should orient their research (...) on the practical problems raised by building and developing our country in the context of globalization and international economic integration. Secondly, one of the important tasks for Vietnamese philosophers is to research the philosophical thought of Vietnam. Thirdly, one of the no less important tasks for people engaging in research and teaching of philosophy in Vietnam is to investigate the trends and ideas of preeminent world philosophers, both in the East as well as in the West.

Ultra-high-performance concrete (UHPC) is gaining popularity due to its superior mechanical properties, including high strength, toughness, durability, and excellent seismic performance. However, the risk of explosive spalling in UHPC structures exposed to fire poses a significant challenge, fundamentally hindering comprehensive studies on fire safety and limiting the broader engineering applications of UHPC. In this study, the mixture proportion of UHPC was developed and optimized by comparing the usage of yellow river and standard sands, different types of chemical admixtures, and different (...) curing regimes. Furthermore, a sensitive case study was also conducted to optimize the calcined bauxite content to improve UHPC's fire resistance. For these purposes, 189 UHPC cubes, incorporating variations in particle types, superplasticizer types, and curing regimes, were tested under three thermal levels, such as 200℃,400℃, and 600℃. The microstructural evolution of heated cube specimens was then observed using a scanning electron microscope (SEM) examination. Calcined bauxite was then considered to replace the standard sand to improve the fire resistance of UHPC and enhance the residual compressive strength of cube specimens under thermal conditions. For this purpose, 0%, 20%, 40%, 60%, 80%, and 100% calcined bauxite content was designed as six case studies. Furthermore, the degradation of UHPC strength was also investigated for the corresponding six case studies by conducting the uniaxial compressive experiments. Finally, the microstructural evolution under both thermal conditions and calcined bauxite content was observed and discussed. (shrink)

Nowadays, the power systems are getting more and more complicated because of the delays introduced by the communication networks. The existence of the delays usually leads to the degradation and/or instability of power system performance. On account of this point, the traditional load frequency control approach for power system sketches a destabilizing impact and an unacceptable system performance. Therefore, this paper proposes a new LFC based on adaptive integral second-order sliding mode control approach for the large-scale power system with communication (...) delays. First, a new linear matrix inequality is derived to ensure the stability of whole power systems using Lyapunov stability theory. Second, an AISOSMC law is designed to ensure the finite time reachability of the system states. To the best of our knowledge, this is the first time the AISOSMC is designed for LFC of the LSPSwCD. In addition, the report of testing results presents that the suggested LFC based on AISOSMC can not only decrease effectively the frequency variation but also make successfully less in mount of power oscillation/fluctuation in tie-line exchange.

Since 2013, Vietnam has implemented a plan to reform the whole education sector. However, there is little understanding on the status of educational research in Vietnam, which may lay the foundation for such plan. Thus, this research aims to analyze the whole picture of educational research from Vietnam, as seen from the Clarivate Web of Science (WOS) database: 215 publications were recorded, ranging from 1991 to 2018. These 215 publications were further analyzed from five perspectives: 1) number of publications by (...) year; 2) research fields and levels of education; 3) top institutions with the highest number of publications; 4) international collaboration; and 5) quality. Some of the most notable results are: 1) the educational sciences in Vietnam have been still under-developed until recently; 2) among different research topics research among educational sciences, some (e.g., Vocational Education and Training or Early Childhood Education) seemed to be overlooked whereas others (e.g., Higher Education and Teaching and Learning) seemed to receive more attention from educational scholars; 3) all the most major education – specialized universities did not appear among the top five institutions with highest number of publications; 4) Australia, Thailand, the USA, New Zealand and China were the countries with the highest number of co-publications with Vietnamese researchers; and 5) The majority of publications belonged to low-ranked journals. Implications would be withdrawn for Vietnamese policymakers, education leaders, educational researchers and teachers in order to adjust their policies and/or action plans; thus, enhancing the performance and impacts of educational research in the future.

This article aims at conceptualising the notion of embarrassment as a negativistic figure of thought that takes the experience of one’s own non-sovereignty as a starting point and emphasises an engagement with situations of not-knowing. This consideration is clarified in discussion with the figure of Socrates or with the philosophical attitude of Socrates. Because the negativistic thrust of the conceptualisation undertaken is reminiscent of irony, the paper then addresses the question of what distinguishes embarrassment understood as a figure of thought (...) from irony. For this purpose, Kierkegaard’s reading of Socratic irony is drawn upon. It is shown that irony is inherently a negativism, which in the last consequence aims at a retention of rights; but this is exactly what embarrassment avoids, because, as the article shows, it is not a negativism of strength, but of weakness.

Relationships with international students can be beneficial to higher education in terms of financial and human resources. For this reason, establishing and maintaining such relationships are usually pre-eminent concerns. In this study, we extended the application of the disconfirmation expectation model by incorporating components from subjective task value to predict the loyalty of international students toward their host countries. On a sample of 410 Vietnamese students enrolled in establishments of higher education in over 15 countries across the globe, we employed (...) structural equation model to construct the conceptual model. Our empirical findings revealed that while the roles of satisfaction and disconfirmation are still important as direct and indirect antecedents of international student loyalty, its most powerful predictors are the three components of subjective task value: attainment, utility and intrinsic. These insights result in a number of implications for actors on the higher ducation scene, such as heads of institutions and policy makers. (shrink)

This research investigates the factors influencing the disparity between domestic gold prices (SJC gold and 9999 gold) and global gold prices in Vietnam from January 2011 to December 2023. Using the Autoregressive Distributed Lag (ARDL) model, we identify key macroeconomic determinants impacting this price spread, including interest rates, oil prices, and consumer demand. Our findings reveal that higher interest rates are associated with larger price spreads, suggesting that monetary policy plays a significant role in the domestic gold market. Oil prices (...) exhibit a negative relationship with the price spread for 9999 gold, indicating that rising oil prices tend to align domestic gold prices more closely with global trends. Consumer demand notably affects the SJC_Global price spread but not the 9999_Global spread, reflecting the different market dynamics of finished goods versus raw materials. Additionally, the error correction terms in both models indicate a robust mechanism for long-term equilibrium, demonstrating the Vietnamese gold market’s resilience. These insights highlight the need for policymakers to reconsider existing regulations, such as Decree 24, to ensure a stable and efficient gold market. The study concludes that while the Vietnamese gold market exhibits sustainable practices, regulatory revisions are necessary to support both market growth and community development. Future research should consider additional macroeconomic variables and the impact of regulatory changes over time to further understand the dynamics of gold price disparities in Vietnam. (shrink)

Computational drug repositioning has been proven as a promising and efficient strategy for discovering new uses from existing drugs. To achieve this goal, a number of computational methods have been proposed, which are based on different data sources of drugs and diseases. These methods approach the problem using either machine learning- or network-based models with an assumption that similar drugs can be used for similar diseases to identify new indications of drugs. Therefore, similarities between drugs and between diseases are usually (...) used as inputs. In addition, known drug-disease associations are also needed for the methods as prior information. It should be noted that those associations are still not well established due to the fact that many of marketed drugs have been withdrawn and this could affect the outcome of the methods. In this study, we propose a novel method named RLSDR to find new uses of drugs. More specifically, it relies on a semi-supervised learning model, Regularized Least Square, thus it does not require definition of non-drug-disease associations as previously proposed machine learning-based methods. In addition, the similarity between drugs measured by chemical structures of drug compounds and the similarity between diseases which share phenotypes can be represented in a form of either similarity network or similarity matrix as inputs of the method. Moreover, instead of using a gold-standard set of known drug-disease associations, we construct an artificial set of the associations based on known disease-gene and drug-target associations. Experiment results demonstrate that RLSDR achieves better prediction performance on the artificial set of drug-disease associations than that on the gold-standard ones in terms of area under the Receiver Operating Characteristic curve. In addition, it outperforms two representative network-based methods irrespective of the prior information of drug-disease associations. Novel indications for a number of drugs are also identified and validated by evidences from a different data resource. (shrink)

Il y a trop de distance entre les conceptions abstraites de la Physique et les modèles intuitifs empruntés à l'univers concret pour que l'on puisse espérer tirer de l'utilisation de ceux-ci des indications exactes. Il faut recourir à des modèles déjà conceptuels et abstraits empruntés plutôt à l'univers mathématique qu'à l'univers sensible.

Harcourt argues that in clinical contexts, children and young people with mental health illness can experience epistemic, specifically testimonial, injustice when their perspectives are unjustifiably discounted by health service providers.1 Our goal in this commentary was to illustrate how caregivers, a critical component of CYP treatment triad, can also engage in testimonial injustice towards CYP patients. Testimonial injustice occurs when one suffers a credibility deficit and that credibility deficit is based on prejudice.2 Harcourt expands Fricker’s account of testimonial injustice by (...) arguing that for CYPs, the credibility deficits attributed to them by clinicians, for example, may result from epistemic arrogance in that CYPs are viewed as having unreliable knowledge about their condition. Harcourt writes: ‘Being a CYP is treated as a heuristic for epistemic unreliability across a wide range of domains’, including clinical settings. Harcourt’s expansion of Fricker’s account thus includes epistemic arrogance as an alternative necessary condition, in addition to prejudice, to apply the concept of testimonial injustice. We think Harcourt’s argument can also be extended to caregivers, who are central to the CYP treatment triad. We illustrate how this may be the case by drawing from research we conducted to understand the perspectives of clinicians and prospective families, both caregivers and paediatric patients with obsessive–compulsive disorder about the possibility of ….

Motivated by exploitation concerns, we argue for the importance of participant engagement in basic human intracranial electrophysiology research. This research takes advantage of unique neurosurgical opportunities to better understand complex systems of the human brain, but it also exposes participants to additional risks without immediate therapeutic intent. We argue that understanding participant values and incorporating their perspectives into the research process may help determine whether and to what extent research practices and the resulting distributions of risks and benefits constitute exploitation (...) and contribute to building a brain research paradigm that is genuinely responsive to participant values. More broadly, we highlight the importance of paying attention to participant interests in non-therapeutic brain research. (shrink)

Geht es um die Frage, welche Faktoren zur Akzeptanz und Verbreitung von Verschwörungserzählungen beitragen, so verweist die Forschungsliteratur zur Erklärung oft auf sehr allgemeine Bedürfnisse, die in der Regel als anthropologische Gegebenheiten aufgefasst werden, wie etwa das Bedürfnis nach Sinngebung und Orientierung. Der vorliegende Artikel weist auf die möglichen Probleme einer anthropologischen Verkürzung der Sachlage bei solchen Erklärungsansätzen hin und formuliert einen genealogischen Ansatz, der es erlaubt, jene Bedürfnisse, die den Verschwörungsglauben begünstigen, als Resultat eines historisch voraussetzungsreichen Subjektivierungsprozesses zu begreifen. (...) Zur Beschreibung jenes Prozesses werden in Auseinandersetzung mit Nietzsches Genealogie der Moral insbesondere die Motive des Ressentiments und der Schuld als Triebkräfte herangezogen, die insbesondere unter säkularen Bedingungen Projektionsweisen befördern, auf denen Verschwörungserzählungen beruhen.

Recent advancements in neuroengineering research have prompted neuroethicists to propose a variety of “ethical guidance” frameworks (e.g., principles, guidelines, framing questions, responsible research innovation frameworks, and ethical priorities) to inform this work. In this chapter, we offer a comparative analysis of five recently proposed ethical guidance frameworks (NIH neuroethics guiding principles, Nuffield Council on Bioethics, Global Neuroethics Summit Delegates, the Center for Neurotechnology’s neuroethical principles and guidelines, and the Neurotechnology Ethics Taskforce’s ethical priorities). We identify some common themes among these (...) frameworks, making explicit significant areas of convergence. We also highlight three areas of ethical consideration that have not received sufficient attention across these frameworks (extended care for research participants, cultural salience, and stakeholder input). Further attention and analysis of these three areas would improve the breadth and scope of ethical considerations for neuroengineering research. (shrink)

Men who spend a greater proportion of time apart from their female partner since the couple’s last copulation are at greater “objective” sperm competition risk. We propose a novel cue to sperm competition risk: the time she spends with her male friends. Four hundred and twenty men in a committed, heterosexual, sexual relationship completed a questionnaire. The results indicate that men at greater objective sperm competition risk report less time desired until the couple’s next copulation, greater interest in copulating with (...) their partner, and greater anger, frustration, and upset in response to their partner’s sexual rejection, but only among men whose partner spends more time with her male friends. These results remain after controlling statistically for the participant’s age and their partner’s age. We discuss limitations of the current research, and discuss how research in human sperm competition can inform social issues, including men’s partner-directed sexual coercion. (shrink)

Among contemporary liberal political theorists in the West, there appears to be a standoff between two camps. One camp promotes tighter social bonds through collective responsibility and patriotic fellow-feeling while the other insists on the need for relaxed social bonds through respect for individual freedom. This essay shows how two Vietnamese thinkers—Ho Chi Minh (1872–1969) and Nguyen Manh Tuong (1909–1997)—can help move this intractable debate about collective responsibility and individual freedom beyond statements of principle to a more pragmatic discussion of (...) what should be done to maintain a healthy polity. They present an alternative to the static standoff, arguing that dynamic oscillation between two activities can forge national fraternal solidarity while also respecting individual freedom when the needs arise: ‘criticism and self-criticism' which tightens social bonds, and ‘liberal self-exploration' which relaxes social bonds.

Motivated by the increasing economic significance of investment advisory industries and the prevalence of wrongdoing in financial planning services, we examine whether, and to what extent, employee misconduct is shaped by their local corruption culture. Using novel data of more than 4.7 million adviser-year observations of financial advisers and the Department of Justice’s data on corruption, we find that financial advisers and advisory firms located in areas with higher levels of corruption are more likely to commit misconduct. These results hold (...) for both individual advisor and firm level analyses and are robust to the use of various fixed effects, model specifications, proxies for corruption and misconduct, and an instrumental variable approach. Using the passage of the Dodd-Frank Whistleblower Provision, which provides incentives for reporting corruption incidences and thereby reduces the incentives for fraud, we find that the relation between local corruption culture and adviser misconduct is attenuated after the provision enacted by the SEC. Overall, our study highlights the externalities of corruption culture on individual ethics and the essential role of whistleblowing laws in reducing corruption-prone norms. (shrink)

This paper introduces a novel method to control the operation of the active suspension system. In this research, a quarter-dynamic model is used to simulate the vehicle’s vibrations. Besides, the sliding mode-PID-integrated algorithm with five state variables is proposed to be used. This is a completely original and novel algorithm. The process of establishing the control algorithm is clearly described. The simulation is performed by the MATLAB software. The results of the paper have shown the advantages of the sliding mode-PID (...) algorithm used in this research. Accordingly, the displacement and acceleration of the sprung mass were significantly reduced when this algorithm was used. The maximum and average values of the displacement of the sprung mass are only 1.31% and 1.29%, respectively, compared with the situation of the vehicle using a passive suspension. Similarly, the value of the acceleration is 6.98% and 2.94%, respectively. In addition, the phenomenon of “chattering” has also been significantly reduced when using this controller. In the future, some more complex algorithms can be proposed. (shrink)

The relationship between greenwashing and visitors' green behavior remains an under-researched topic in the tourism and hospitality literature, despite evidence of the harmful effect of greenwashing on the reputation and competitive advantage of organizations. This study extends attribution theory into the green context to develop a research framework for investigating the interrelationship between greenwashing, green trust, and green word-of-mouth (WOM), especially the roles of green trust and connectedness to nature. We conducted a survey of 289 visitors staying in four- and (...) five-star hotels in Vietnam. The findings indicated that hotels should avoid greenwashing due to its negative impact on visitors' green trust and green WOM. Moreover, the study found that greenwashing had an indirect and negative influence on green WOM based on visitors' green trust. Importantly, the research revealed the value of connectedness in moderating green attitudes and behaviors among visitors. (shrink)

The recent availability of multiple avian genomes has laid the foundation for a huge variety of comparative genomics analyses including scans for changes and signatures of selection that arose from adaptions to new ecological niches. Nocturnal adaptation in birds, unlike in mammals, is comparatively recent, a fact that makes birds good candidates for identifying early genetic changes that support adaptation to dim‐light environments. In this review, we give examples of comparative genomics analyses that could shed light on mechanisms of adaptation (...) to nocturnality. We present advantages and disadvantages of both “data‐driven” and “hypothesis‐driven” approaches that lead to the discovery of candidate genes and genetic changes promoting nocturnality. We anticipate that the accessibility of multiple genomes from the Genome 10K Project will allow a better understanding of evolutionary mechanisms and adaptation in general. -/- . (shrink)
