This paper investigates the nonlinear vehicle platoon control problems with external disturbances. The quadratic spacing policy is applied into the platoon control, in which the desired intervehicle distance is a quadratic function in terms of the vehicle’s velocities. Comparing with the general constant time headway policy, the QSP is more suitable to the human driving behaviors and can improve the traffic capacity. Then, a novel platoon control scheme is proposed based on the distributed integrated sliding mode. Since the external disturbances (...) are taken into consideration, the sliding mode method is employed to handle the disturbances. Moreover, the stability and string stability of the proposed platoon control system are strictly analyzed. In final, numerical simulations are provided to verify the proposed approaches. (shrink)

The influence of corporate social performance on stakeholders is one of the focal issues in corporate social responsibility research. Using data of listed companies in China, this paper examines whether CSR behavior in the form of charitable donations garners a positive reaction from suppliers. Results derived from both level and change model regressions show that superior CSP makes it easier for a firm to obtain trade credit from suppliers, although the effect is significant only in non-state-owned enterprises. The results are (...) robust to various measures of CSP and endogeneity tests. The results support the strategic philanthropy view and apply stakeholder theory in supply chain, that strategic CSR can help firms to attract suppliers and consolidate cooperative relationships with them, which in turn benefits the firms in terms of more trade credit financing from suppliers. This paper also shows that state-owned enterprises and non-SOEs have different CSR intentions and use CSR to achieve strategic goals in different ways. The conclusions drawn from this study provide practical guidance on CSR strategy, suggesting that CSR activities can help a firm in transition economies to enhance its corporate image, establish and consolidate the good relationship with suppliers, and obtain economic benefits or achieve long-term business objectives.

This book examines the pedagogical encounters within children's ecological and socio-cultural historical contexts, and aspects of playful learning and development within these contexts. It addresses research and practices varying across learning contexts, providing easily adaptable exemplary practices leading to children's positive learning and development. The book offers a unified general cultural-historical theoretical model for exploring new contexts at different stages of children's learning and development. It suggests studying contexts as a source of development, as social situations of development. It analyzes (...) play, early learning and the transition from play to school learning. It also explores the role of teachers and parents in supporting the development of executive functions, digital literacy, creative inquiries, problem solving and creativity as necessary and important prerequisites of children's school academic achievements. This volume contributes to the discourse on how children's learning is shaped in the 21st century era. It equips educators and parents with new and effective methods of creating developing contexts in their daily practice and to fully utilize the developing potential of existing contexts. (shrink)

This book presents an exhaustive study of the three 13-century discussions explicitly dealing with the notion of Significatio. The study aims to show that the three discussions emerge because of apparently opposite claims about the signification of words in the authoritative literature of the period. It also shows that the three discussions develop in the same direction - towards a unified use of the notion of signification, which keeps its explanatory role in semiotics, but loses its role in grammar and (...) logic.

Study on the fundamentals of Mimamsa philosophy.

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

We present a dynamic approach to Peirce’s original construal of abductive logic as a logic of conjecture making, and provide a new decidable, contraction-free and cut-free proof system for the dynamic logic of abductive inferences with neighborhood semantics. Our formulation of the dynamic logic of abduction follows the philosophical and scientific track that led Peirce to his late, post-1903 characterization of abductive conclusions as investigands, namely invitations to investigate propositions conjectured at the level of pre-beliefs.

This study explores the research paradigms of contemporary business ethics research in 2001–2008. With citation data from the top two business ethics journals included in the Social Sciences Citation Index, this study conducts citation and co‐citation analysis to identify the most important publications, scholars, and research themes in the business ethics area and then maps the intellectual structure of business ethics studies between 2001 and 2008. The results show that current business ethics studies cluster around four major research themes, including (...) morality and social contract theory, ethical decision making, corporate social responsibility, and stakeholder theory. This study helps profile the invisible network of knowledge production in business ethics and provides important insights on current research paradigms of business ethics studies. (shrink)

Research investigating the underlying mechanisms and boundary conditions under which leader humility influences employee voice remains underdeveloped. Drawing from approach–inhibition theory of power and leader humility literature, we developed a moderated-mediation model in which personal sense of power (i.e., employees’ ability to influence other individuals such as their leader) was theorized as a unique mechanism underlining why employees feel motivated to speak up under the supervision of humble leaders. Additionally, the cultural value of power distance was proposed to be a (...) relevant boundary condition to influence such relationship. We tested the model using time-lagged supervisor–subordinate matched data. Results of mixed models analyses provided support for our hypotheses confirming that employees’ personal sense of power mediates the relationship between leader humility and employee voice, and such relationship was found to be stronger when employees’ power distance was lower rather than higher.

Since learners’ academic achievement is the ultimate goal of any system of education, multitudes of studies have been conducted on this variable and its determinants. That is, several scholars have explored the effects of student-related and teacher-related factors on learners’ academic achievement. Notwithstanding, a few researchers have investigated the effects of teachers’ self-efficacy and creativity on learners’ academic achievement. Furthermore, no study has reviewed the role of these teacher-related factors in learners’ achievement. Therefore, the present study seeks to bridge the (...) lacunas by delving into the influence of teachers’ self-efficacy and creativity on English as a Foreign Language learners’ academic achievement. The beneficial effects of self-efficacy beliefs and creative teaching were outlined through the existing evidence. This seems to be illuminative for EFL teachers. Given the positive consequences of teachers’ self-efficacy for students’ achievement, EFL teachers should believe in themselves and their abilities to lead their students to academic success. Additionally, with regard to the positive impact of teachers’ creativity on learners’ achievement, EFL teachers are expected to teach the course content creatively. (shrink)

This study provides a general overview of contemporary business ethics research of the last 10 years (1997-2006) and discusses potential future research directions in business ethics based on the overview. Using citation and co-citation analysis, this study examined the citation data of journal articles, books, and other publications collected in the Social Sciences Citation Index (SSCI), wherein key research themes in business ethics studies in 1997—2006 and correlations between these themes were explored. The results show that major research themes in (...) business ethics have shifted in the last decade from research on ethical decision making and on the relationship between corporate social responsibility and corporate performance to research on stakeholder theory in business ethics and on the relationship between consumer behavior and corporate social responsibility. The results of this study help map the invisible network of knowledge production in business ethics research and provide important insights on future business ethics research. (shrink)

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

Research in the fields of complex problem solving (CPS) and dynamic decision making using microworlds has been mainly conducted in Western industrialized countries. This study analyzes the CPS process by investigating thinking‐aloud protocols in five countries. Participants were 511 students from Brazil, Germany, India, the Philippines, and the United States who worked on two microworlds. On the basis of cultural‐psychological theories, specific cross‐national differences in CPS strategies were hypothesized. Following theories of situatedness of cognition, hypotheses about the specific frequency of (...) problem‐solving strategies in the two microworlds were developed. Results of the verbal protocols showed (a) modification of the theoretical CPS model, (b) task dependence of CPS strategies, and (c) cross‐national differences in CPS strategies. Participants’ CPS processes were particularly influenced by country‐specific problem‐solving strategies. (shrink)

From the tape-recording of naturally occurring Chinese psychotherapy sessions, this article explores how repeated occurrences of resistance are managed in the course of interactional sequences and the participants’ actions within these sequences. By employing the methods of conversation analysis, we discuss the main discursive strategies employed by the clients to express their resistance and investigate how the therapist manages this. We find that clients show their resistance to the therapist’s questions in four ways: keeping silence, providing minimal response, making non-answer (...) responses, and being over-talkative. Persistent asking is the main technique we identify in the data for the therapist to manage the resistance; in the meantime, asking questions in a stepwise way, making requests after facing resistance to questions, active retreating and reformulating of the client’s words are employed as subsidiary techniques. The successful management of resistance leads to a smooth sequential development of the psychotherapy, while inappropriate strategies might result in a halt or even breakdown of the therapeutic work. In psychotherapy, resistance is a result of the shared interaction between client and therapist. It is such a complex issue that, in order to understand and manage it, we also take into consideration the broader social and cultural context in which it occurs. (shrink)

Peirce wrote in late 1901 a text on formal logic using a special Dragon-Head and Dragon-Tail notation in order to express the relation of logical consequence and its properties. These texts have not been referred to in the literature before. We provide a complete reconstruction and transcription of these previously unpublished sets of manuscript sheets and analyse their main content. In the reconstructed text, Peirce is seen to outline both a general theory of deduction and a general theory of consequence (...) relation. The two are the cornerstones of modern logic and have played a crucial role in its development. From the wider perspective, Peirce is led to these theories by three important generalizations: propositions to all signs, truth to scriptibility, and derivation to transformability. We provide an exposition of such proposed semiotic foundation for logical constants and point out a couple of further innovations in this rare text, including the sheet of assertion, correction as a dual of deduction and the nature of conditionals as variably strict conditionals.

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

Peirce introduced Existential Graphs in late 1896, and they were systematically investigated in his 1903 Lowell Lectures. Alpha graphs for classical propositional logic constitute the first part of EGs. The second and the third parts are the beta graphs for first-order logic and the gamma graphs for modal and higher-order logics, among others. As a logical syntax, EGs are two-dimensional graphs, or diagrams, in contrast to the linear algebraic notations. Peirce's theory of EGs is not only a theory of logical (...) syntax but also a proof theory for many logics. A set of transformation rules of graphs defines a proof system for a graphical logic.

This paper presents a bioinspired lower extremity exoskeleton robot. The proposed exoskeleton robot can be adjusted in structure to meet the wearer’s height of 150–185 cm and has a good gait stability. In the gait control part, a method of identifying different locomotion modes is proposed; five common locomotion modes are considered in this paper, including sitting down, standing up, level-ground walking, ascending stairs, and descending stairs. The identification is depended on angle information of the hip, knee, and ankle joints. (...) A deep locomotion mode identification model based on long-short term memory architecture is proposed in this paper for exploiting the angle data. We conducted two experiments to verify the effectiveness of the proposed method. Experimental results show that the DLMIM is capable of learning inherent characteristics of joint angles and achieves more accurate identification than the other models. The last experiment demonstrates that the DLMIM can recognize transitions between different locomotion modes in time and the real-time performance varies with each individual. (shrink)
