The suspension system is referred to as the set of springs, shock absorbers, and linkages that connect the car to the wheel system. The main purpose of the suspension system is to provide comfort for the passengers, which is created by reducing the effects of road bumpiness. It is worth noting that reducing the effects of such vibrations also diminishes the noise and undesirable sound as well as the effects of fatigue on mechanical parts of the vehicle. Due to the (...) importance of the abovementioned issues, the objective of this article is to reduce such vibrations on the car by implementing an active control method on the suspension system. For this purpose, a conventional first-order sliding mode controller has been designed for stochastic control of the quarter-car model. It is noteworthy that this controller has a significant ability to overcome the stochastic effects, uncertainty, and deal with nonlinear factors. To design a controller, the governing dynamical equation of the quarter-car system has been presented by considering the nonlinear terms in the springs and shock absorber, as well as taking into account the uncertainty factors in the system and the actuator. The design process of the sliding mode controller has been presented and its stability has been investigated in terms of the Lyapunov stability. In the current research, road surface variations are considered as Gaussian white noise. The dynamical system behavior for controlled and uncontrolled situations has been simulated and the extracted results have been presented. Besides, the effects of existing uncertainty in the suspension system and actuator have been evaluated and controller robustness has been checked. Also, the obtained quantitative and qualitative compressions have been presented. Moreover, the effect of controller parameters on the basin of attraction set and its extensiveness has been assessed. The achieved results have indicated the good performance and significant robustness of the designed controller to stabilize the suspension system and mitigate the effects of road bumpiness in the presence of uncertainty and noise factors.

BackgroundCultural competence is considered as one of the main skills of nurses enabling them to provide nursing care for those with different cultures. One of the cases related to nurses’ cultural competence is observance of ethical codes, but it has not been investigated sufficiently in studies.AimThis study has been conducted to determine the relationship between nurses’ cultural competence and observance of ethical codes in practice.Research designThis descriptive-correlational study was conducted in 2020. Sampling was done at several stages. The data were (...) collected using questionnaires of demographic information, cultural competence, and observance of ethical codes as self-report. The questionnaires were provided to the subjects by the corresponding researcher and the data were analyzed using Pearson correlation test.Participants and research contextThis study was done with participation of 267 nurses working in four training hospitals located in northwestern Iran and 16 head nurses of selected wards.Ethical considerationsThe study was approved by Human Ethics Committee of Hamadan University of Medical Sciences. Participation was voluntary. Consent was obtained and confidentiality kept.FindingsThe results of Pearson correlation coefficient test showed a positive and statistically significant relationship between cultural competence and observance of ethical codes (r = 0.524, p = 0.001). In addition, cultural competence and observance of ethical codes by most nurses were at a moderate level.ConclusionsThe results of the present study showed a significant relationship between nurses’ cultural competence and observance of ethical codes. Therefore, it can be concluded that by strengthening the level of nurses, the level of observing ethical codes by them can be increased. Cultural competency and observance of ethical codes are important components of nursing care, and their development can improve nursing care delivery to clients through academic training, hidden curriculum and in-service education.

This volume explores the reorganisation of knowledge taking place in the course of Galileo's research process extending over a period of more than thirty years, pursued within a network of exchanges with his contemporaries, and documented by a vast collection of research notes. It has revealed the challenging objects that motivated and shaped Galileo's thinking and closely followed the knowledge reorganization engendered by theses challenges. It has thus turned out, for example, that the problem of reducing the properties of pendulum (...) motion to the laws governing naturally accelerated motion on inclined planes was the mainspring for the formation of Galileo's comprehensive theory of naturally accelerated motion.

It is deemed that the effectiveness of teachers is highly entangled with psycho-emotional constructs, such as critical thinking (CT), emotion regulation (ER), and immunity. Despite the potential roles of CR, ER, and immunity, their possible relationships have remained unexplored in the higher education context of Iran. To fill in this lacuna, this study explored the potential role of CT and ER in university teachers' immunity in the Iranian higher education context. For this purpose, a total of 293 English university teachers (...) were selected using a convenience sampling method. They were invited to fill out the Watson–Glaser Critical Thinking Appraisal-Form, Language Teacher Emotion Regulation Inventory, and Language Teacher Immunity Instrument. The findings of path analysis indicated that the university teachers with higher CT were more productively immunized. Moreover, the results revealed that ER could predict the university teachers' immunity. The findings of the study lead to this implication that higher order thinking skills, emotion regulatory strategies, and immune enhancement should be incorporated into educational programs of higher education.

Utilization of renewable energies in association with energy storage is increased in different applications such as electrical vehicles, electric boats, and smart grids. A robust controller strategy plays a significant role to optimally utilize the energy resources available in a power system. In this paper, a suitable controller for the energy resources of an EB which consists of a 5 kW solar power plant, 5 kW fuel cell, and 2 kW battery package is designed based on the linear parameter varying (...) controller design approach. Initially, all component dynamics are augmented, and by exploiting the sector-nonlinearity approach, the LPV representation is derived. Then, the LPV control method determines the suitable gains of the states’ feedbacks to provide the required pulse commands of the boost converters of the energy resources to regulate the DC-link voltage and supply the power of EB loads. Comparing with the state-of-the-art nonlinear control methods, the developed control approach assures the stability of the overall system, as it considers all component dynamics in the design procedure. The real-time simulation results demonstrate the performance of the designed controller in the creation of a constant DC-link voltage. (shrink)

The study focuses on the mobile telecommunications industry in Afghanistan prior to the Taliban takeover of the country in 2021 and seeks to study how the mobile telecommunications corporations engage with the different area-specific governance systems in order to gain legitimacy to operate across Afghanistan. The study capitalises on mixed qualitative data to conduct an embedded case study of the Afghan mobile telecommunications industry as an extreme context for understanding business-society relations in South Asia. Theoretically, the article integrates insights from (...) governance literature on areas of limited statehood to conceptualise business–society relations in Afghanistan beyond state-centric views and assumptions. The findings result in two modalities of business engagement that are conceptualised as a single vis-à-vis multiple governance system approach. Each of these modes of engagement implies a political nature and role for the businesses that are embedded in ethical dilemmas as discussed in the article. These findings contribute to the debate on the ‘political turn’ in the CSR literature and the governance literature on areas of limited statehood. (shrink)

Propositional logic, with the aid of SAT solvers, has become capable of solving a range of important and complicated problems. Expanding this range, to contain additional varieties of problems, is subject to the complexity resulting from encoding counting constraints in conjunctive normal form. Due to the limitation of the expressive power of propositional logic, generally, such an encoding increases the numbers of variables and clauses excessively. This work eliminates the indicated drawback by interpolating constraint symbols and the set of natural (...) numbers \ into the alphabet of propositional logic and adjusting the underlying language accordingly. In the extended logic counting constraints are naturally formulated, while many important aspects, such as Boolean nature and the soundness and completeness theorems, are kept preserved. (shrink)

Considering that in times of state of emergency or civil emergency (such as the pandemic caused by COVID 19), governments in many countries around the world have restricted human rights and freedoms through legally binding government decrees. These restrictive measures increasingly raise dilemmas about their effect and possible violations by the government of international norms guaranteeing human rights. The paper aims to analyze whether these restrictive measures set out in the decisions of the Government of the Republic of Northern Macedonia (...) (RNM) are in compliance with the derogations allowed under the European Convention on Human Rights and Freedoms (ECHR) and the positive laws in power. In the framework of this paper is analyzed whether these measures have the sole purpose of protecting the health of citizens or not. The work is limited in terms of time (as long as the state of emergency lasted three months) and territory (government decrees with the force of law). Descriptive, historical, analytical, comparative and citizen survey methods are used in this paper. Government decrees have been analyzed in order to assess whether they were prudent, in accordance with international standards and consequences that they have caused to citizens. The conclusions provide data on whether the management of the situation has been appropriate or not and to what extent it has been effective, as well as how much it has been within the international framework and how they have affected the quality of life of citizens.

O presente artigo busca, a partir da filosofia de Michel de Montaigne, explicitar quais lições podemos aprender sobre o contexto de epidemia em que vivemos. Mas, afinal, aqui fica a pergunta fundamental deste texto: o que podemos aprender com um filósofo francês do século XVI, Michel de Montaigne, sobre esse momento tão devastador que estamos vivendo? É claro que Montaigne não nos dirá nada sobre a natureza do vírus, nem sobre nosso sistema imunológico, muito menos sobre metodologias de investigação científicas (...) para a procura de medicamentos para o tratamento da doença. O que Montaigne nos pode ensinar é algo de outra ordem, não da biológica, mas, da subjetiva. É uma (nova) disposição de nosso espírito que podemos aprender a desenvolver com o filósofo. (shrink)

The roots of ‘ancient sport’, or Zurkhaneh, as its name implies, go back to ancient Iran and the rituals of Mithraism, in which believers pray and learn morality and humanity in cave-shape temples built in connection with running water. After the advent of Islam and the fall of the ancient religions, temples gave way to Zurkhanehs, and athletes who, while learning moral teachings, cultivated physical strength to resist external enemy forces and internal oppression, grown in those Zurkhanehs. With a tendency (...) to Sufism, Shi`ism and following the first Imam of the Shiites, athletes became heroes and knights, many of whom today, after hundreds of years, are still the cultural myths of the people of Iran. The ancient sports such as wrestling are a symbol of human and moral virtues, the promotion of which can lead to the growth and development of the moral beauty and chivalry culture among all athletes in various sports and lead to institutionalize characteristics of heroism and magnanimity in society. Ancient sports exercising tools, art and architecture of Zurkhaneh, poems, rituals and personalities form the nature of Zurkhaneh and ancient sports have a great impact on the formation of heroic identity and the way to perform the sport movements with the special instruments of Zurkhaneh, which is accompanied by epic and religious poems. In fact, Zurkhaneh instruments, the type of poems that are recited and the existence of epic and religious patterns complement each other. This process increases the effect of Zurkhaneh on the formation of athletic and heroic identity among sportsmen. As such, it will be suggested that Zurkhareh offers an ethical ideal from which globalized Western sport can learn. (shrink)

This study pragmatically makes a descriptive analysis of metadiscourse in academic lectures from the perspective of the relevance-adaptation theory. Based on the relevance theory and the adaptation theory, the relevance-adaptation model is constructed to explore the occurrence, the pragmatic description and the role of metadiscourse in academic lectures. The data is collected from George Lakoff’s 10 academic lectures on cognitive linguistics at Beijing University of Aeronautics and Astronautics in 2004 and some academic lectures audio-taped in classrooms. The results of the (...) study show that 1) the occurrence of metadiscourse in academic lectures is pervasive; 2) the process of choosing appropriate metadiscourse is dynamic and the result of searching for relevance and making contextual adaptations – the process of searching for relevance of metadiscourse is measured in terms of three pairs of the distinctions, namely, contextual effect and processing effort, explicature and implicature, and conceptual meaning and procedural meaning, and contextual adaptations of metadiscourse are constrained by such factors as linguistic reality, psychological motivations and social conventions; 3) the role of metadiscourse in academic lectures is an active discourse constructor.

Direct electrical stimulation has been widely applied in both guidance of lesion resection and scientific research; however, the design and selection of intraoperative cognitive mapping tasks have not been updated in a very long time. We introduce updated mapping tasks for language and non-language functions and provide recommendations for optimal design and selection of intraoperative mapping tasks. In addition, with DES becoming more critical in current neuroscientific research, a task design that has not been widely used in DES yet was (...) introduced for more delicate mapping of brain functions especially for research purposes. We also illustrate the importance of designing a common task series for DES and other non-invasive mapping techniques. This review gives practical updated guidelines for advanced application of DES in clinical and neuroscientific research. (shrink)

Anknüpfend an den Beitrag von U. Steinvorth in Heft 1/1980 wird die Auffassung vertreten, daß die moderne allgemeine Wissenschaftstheorie bisher keine überzeugende Antwort auf die Frage nach dem Status der Politischen Wissenschaft und ihrer theoretischen Erzeugnisse gegeben hat. In diesem Beitrag wird in Auseinandersetzung mit Steinvorth u. a. hervorgehoben: Analog zu der These, daß in der Politik Vernünftigkeit nicht auf Rationalität reduziert werden darf, ist es weder möglich noch wünschenswert, für alle spezifischen politischen Wertungen einen Erklärungstyp zu begründen oder als (...) verbindlich vorzuschreiben. Die Wissenschaftstheorie muß sich in bezug auf die Frage nach dem Status "politischer" Theorien mit einem Theorietypus beschäftigen, der ein neues Abgrenzungskriterium voraussetzt, nämlich einen spezifischen Satz von Prinzipien und Regeln zur Konstruktion politikwissenschaftlicher Theorien.

“The characteristics of China in the world,” as a constant refrain of the contemporary Chinese people, has been discussed in academic circles for nearly a hundred years. It has become more and more popular in recent years, with both government and ambitious scholars continuously appealing for attention to its necessity, significance, and urgency. Obviously, to talk to the world or to be accepted by the world, we must first know who we are and what the world is like. This century-long (...) history of “Chinese education in the world” makes it necessary to consider the historical background when thinking about the characteristics of Chinese education. We attempt to integrate this history into what follows.The ideas... (shrink)

Die Bildwissenschaft, so scheint es, steckt in einer Sackgasse: Teile von ihr sind zur antiaufklärerischen Ideologie geworden, die Interpreten erlaubt, autoritäre Positionen der Auslegung als Macht des Bildes zu beschreiben. Zeit, sie vom Kopf auf die Füsse zu stellen. Um dies einzulösen, rekonstruiert Martin Büchsel akribisch die wichtigsten bildwissenschaftlichen Theorien der letzten Jahrzehnte inklusive ihrer impliziten Ideologien und Mythen und kontrastiert diese mit aufklärerischen Positionen. Dabei bezieht die sorgsam ausgearbeitete Monographie alle international relevanten Theoretiker und Theorien in seine Überlegungen mit (...) ein. Geleistet wird eine fundamentale Kritik der Bildwissenschaften, gleichermassen kann das Buch aber auch als vertiefende Einführung in dieselben dienen. Womit das Potenzial dieser Studie noch keineswegs ausgeschöpft ist: In einem zweiten Teil entwirft Büchsel Eckpfeiler einer zukünftigen, vorstellungskritischen Bildwissenschaft, die Philosophie, Philologie und Kunstgeschichte höchst produktiv miteinander ins Gespräch bringt.

Das weit uber die Zeit seiner Abfassung und uber die Grenzen seines Entstehungslandes hinaus unter dem Namen "Qabusname" bekannte, literarisch wie kulturgeschichtlich bedeutsame Werk heisst wortlich "Buch der Ratschlage," persisch "nasihat-name." Sein Verfasser Kej Kawus wurde um 1021/22 n.Chr. geboren und genoss die fur die persischen Furstensohne seit Jahrhunderten vorgeschriebene Erziehung, bei der eine Synthese von ritterlichen und geistigen, vornehmlich religiosen Tugenden angestrebt wurde. Es handelt sich um eines der interessantesten und eigenartigsten Erzeugnisse der mittelalterlichen iranischen Literatur. Mit Recht werden (...) der intime Ton des Werks und die reizvolle Schlichtheit der hubschen Anekdoten sowie die auf Schmuck verzichtende Einfachheit der Erzahlkunst geruhmt. Die vorliegende Ubersetzung des "Qabusname" ist die erste in deutscher Sprache, die nach dem persischen Original vorgenommen wurde. Die einzige fruhere deutsche Ubersetzung des Orientalisten H. F. von Diez erfolgte aus dem Turkischen und wurde 1811 veroffentlicht. Schon Goethe beschaftigte sich bei seiner Begegnung mit dem klassischen Schrifttum der Perser unter der Fuhrung H. F. von Diez eindringlich mit dem Qabusname. Der Beziehung des Dichters zu diesem so bedeutsamen Stuck der persischen Literatur ist daher ein besonderes Kapitel gewidmet. (shrink)
