The representation of physics problems in relation to the organization of physics knowledge is investigated in experts and novices. Four experiments examine the existence of problem categories as a basis for representation; differences in the categories used by experts and novices; differences in the knowledge associated with the categories; and features in the problems that contribute to problem categorization and representation. Results from sorting tasks and protocols reveal that experts and novices begin their problem representations with specifiably different problem categories, (...) and completion of the representations depends on the knowledge associated with the categories. For, the experts initially abstract physics principles to approach and solve a problem representation, whereas novices base their representation and approaches on the problem's literal features.

Multicellularity in the cellular slime mold Dictyostelium discoideum is achieved by the expression of two types of cell–cell adhesion sites. The EDTA‐sensitive adhesion sites are expressed very early in the developmental cycle and a surface glycoprotein of 24000 Da is known to be responsible for these sites. The EDTA‐resistant contact sites begin to accumulate on the cell surface at the aggregation stage of development. Several glycoproteins have been implicated in the EDTA‐resistant type of cell–cell binding and the best characterized one (...) has an Mr of 80000 (gp80). gp80 mediates cell–cell binding via homophilic interaction and its cell binding site has been mapped to an octapeptide sequence. The mechanism by which gp80 mediates cell–cell adhesion will be discussed. (shrink)

In this study, an adaptive output feedback fault tolerant control scheme is proposed for a class of multi-input and multioutput nonlinear systems with multiple constraints. The neural network is adopted to handle the unknown nonlinearity by means of its superior approximation capability. Based on it, the state observer is designed to estimate the unmeasured states, and the nonlinear disturbance observer is constructed to tackle the external disturbances. In addition, the Nussbaum function is utilized to cope with the actuator faults, which (...) are coupled with the unknown control directions. Combining with the Lyapunov theory, a NN-based output feedback FTC law is developed for the MIMO nonlinear systems, and the boundedness of all closed-loop system error signals is proved. Simulation results on the unmanned helicopter are performed to demonstrate the effectiveness of the proposed controller. (shrink)

In the summer of 1997 one could scarcely enter a bookstore in Beijing without encountering Wang Xiaobo's pensive and defiant look on the cover of dozens of books displayed at the entrance. Wang had suddenly died in the spring of that year at the age of forty-five. Born in Beijing in 1952 to a family of intellectuals, he remained attached to China's capital despite periods of separation, such as during the Cultural Revolution, when he was sent to Yunnan to "learn (...) from the peasants" and taught in a "people-run-school" in Shandong, and also during the 1980s, when he studied in the United States . Wang always returned to Beijing, in the late 1970s to study economy and business at the People's University and in the late 1980s to teach there. After retiring in 1993, he devoted his time to writing: poetry, novels, essays, non-fiction, and a movie script. (shrink)

In post-Gricean pragmatics, communication is said to be successful when a hearer recovers a speaker’s intended message. On this assumption, proposals for ‘what is said’ – the semantic, propositional meaning of a speaker’s utterance – are typically centred around the content the speaker aimed to communicate. However, these proposals tend not to account for the fact that speakers can be deliberately vague, leaving no clear proposition to be recovered, or that a speaker can accept a hearer’s misconstrual even though the (...) speaker didn’t intend it. In such cases, identifying ‘what is said’ is more contentious, even though communication is arguably no less successful. Building on recent interactionist approaches to meaning, this chapter offers a proposal for ‘what is said’ that can account for cases of ‘imperfect’ communication in which the recovery of a speaker’s intention goes awry. This involves taking ‘what is said’ as the co-constructed meaning that the speaker and hearer jointly agree on, giving ‘grounded meanings’ – those mutually and manifestly accepted into the discourse by speaker and hearer – higher precedence in a theory of communication than simply the speaker’s intended meaning. In such cases, rather than speaker and hearer converging at the level of explicit utterance content, communication is expected to be successful as long as the hearer recovers a proposition which is compatible with the speaker’s higher-order discursive goal. The hearer’s uptake is then allowed to override the content of the speaker’s intended meaning in the process of negotiating ‘what is said’. (shrink)

In this article, the researchers explore the following question. Can corporate social responsibility (CSR) and the corporate reputation of a firm lead to its brand equity in business-to-business (B2B) markets? This study discusses CSR from customers' viewpoints by taking the sample of industrial purchasers from Taiwan small-medium enterprises. The aims of this study are to investigate: first, the effects of CSR and corporate reputation on industrial brand equity; second, the effects of CSR, corporate reputation, and brand equity on brand performance; (...) and third, the mediating effects of corporate reputation and industrial brand equity on the relationship between CSR and brand performance. Empirical results support the study's hypotheses and indicate that CSR and corporate reputation have positive effects on industrial brand equity and brand performance. In addition, corporate reputation and industrial brand equity partially mediate the relationship between CSR and brand performance. (shrink)

This paper aims to bridge the relationship between metalinguistic if you like as a non-propositional discourse marker and its conditional counterparts. This paper claims that metalinguistic if you like is polysemous between a hedge that denotes the speaker’s reduced commitment to some aspect of the main clause, and an optional yet potential conditional reading that interlocutors can legitimately draw on in interaction which is brought about due to the ‘if p, q’ sentence form. That is, although the metalinguistic reading is (...) most likely obtained automatically by default, it also carries an available conditional reading that is akin to other metalinguistic conditional clauses such as if you see what I mean. Next, a semantic representation of metalinguistic if you like is developed that takes on board a characterization of conditionality that departs from lexico-grammatical conventions, such that conditionals of the form ‘if p, q’ no longer bear a one-to-one correspondence with “conditional” truth conditions. Employing a radical contextualist semantic framework in which the unit of truth-conditional analysis is not constrained to the sentence form, utterances employing metalinguistic if you like are given a semantic representation such that the if-clause does not contribute propositional content, yet they also maintain their status as conditionals as the sentence form gives rise to a potential conditional secondary meaning.

The present paper analyzes the self‐generated explanations (from talk‐aloud protocols) that “Good” and “Poor” students produce while studying worked‐out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self‐explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such (...) learning results in example‐independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self‐explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self‐explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation‐based learning to account for these psychological findings.

In this article I explore a central paradox of contemporary identity politics: why do we look for recognition from the very institutions we reject as oppressive? I argue that neoliberalism’s continued assault on the bases for collectivity has led to a suspicion that ‘the collective’ is an essentialising concept. The assault on the collective coupled with the neoliberal imperative to create an ‘authentic’ self has led to trauma and victimhood becoming the only bases on which people can unite. This manifests (...) discursively and theoretically in the primary trope of contemporary activism: ‘intersectionality’. Mobilising around this analytical concept has led to an analysis of oppression that, even as it claims to be systemic, is totally dematerialised and relentlessly individualised. Instead of building collective power, we are left with a politics of individual demand coming from a coalition of dispersed subject positions. (shrink)

Philosophy & Social Criticism, Volume 47, Issue 9, Page 1104-1131, November 2021. Contemporary workplaces are mostly hierarchical. Intrinsic and extrinsic bads of workplace hierarchies have been widely discussed in the literature on workplace democracy and workplace republicanism. However, a distinctively intrinsic relational bad, epistemic injustice in the workplace, has largely been neglected by both normative theorists of the workplace and theorists of epistemic injustice. This article, by bringing in the insights of Miranda Fricker’s influential conceptualization of epistemic injustice, argues that (...) hierarchical workplaces have contributed to and reinforced both testimonial and hermeneutical injustices in a central activity of most people’s daily lives. This article argues that these injustices are moral wrongs and thus moral injury to the workers. The article concludes by demonstrating that traditional hierarchy is the most epistemically unjust form of hierarchy, while contestatory hierarchy, because of its emphasis on granting the right to the workers to be listened, is less unjust epistemically.

In 2011 the Journal of Moral Education (JME) celebrated its 40th anniversary of publication. It seemed appropriate to examine and reflect on the JME?s achievements by reviewing its evolution and contribution to the emerging field of moral education and development. Moral education trends, as reflected in the 945 articles published in JME from 1971 to 2011, were investigated by content analysis. The research objectives were: to discover the trends in moral education as represented by published articles and special issues (by (...) analysis of disciplinary approaches, key topics, research methodologies and age-related educational levels) and to examine the international and gender-related development of the journal and the influence of its contributors (by analysis of first authors and editorial board members). The findings identify important concerns, key research topics and neglected areas in moral education and development. Analysis offers an insight into the contribution of JME as the main international interdisciplinary journal in this field, to the history of moral education, to theory and practice and in the changing socio-cultural contexts of the past 40 years. Discussion of the findings is offered, limitations are acknowledged and implications for future directions for the journal considered. (shrink)

This book proposes a semantic theory of conditionals that can account for (i) the variability in usages that conditional sentences can be put; and (ii) both conditional sentences of the form ‘if p, q’ and those conditional thoughts that are expressed without using ‘if’. It presents theoretical arguments as well as empirical evidence from English and other languages in support of the thesis that an adequate study of conditionals has to go beyond an analysis of specific sentence forms or lexical (...) items. The resulting perspective on conditionals is one in which conditionality is located at a higher level than that of the sentence; namely, at the level of thought. The author argues that it is only through adopting such a perspective, and with it, a commitment to context-dependent semantics, that we can successfully represent conditional utterances as they are used and understood by ordinary language users. It will be of interest to students and scholars working on the semantics of conditionals in the fields of linguistics (especially semantics and pragmatics) and philosophy of language. (shrink)

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures that are controlled by criticism, or attempted refutations . As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the problem which we are trying to solve. This (...) is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory ... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ . Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

According to Karl Popper’s critical rationalism, criticism is the only way we have of systematically detecting and learning from our mistakes so as to get nearer to the truth. Meanwhile, it is arguable that the emphasis of Confucianism on creating a hierarchical and harmonious society can easily lead to submission rather than opposition, producing a conformist rather than critical mind. A question arises here as to whether Confucianism tends to denigrate criticism and thus run counter to critical rationalism. In this (...) paper, I first argue that Confucianism prizes criticism and critical discussion, for which ample justification can be found in Confucian classics. Then I compare Confucianism with critical rationalism and assess the compatibility between them. (shrink)

Die Philosophie Helmuth Plessners hat in den letzten Jahren eine Renaissance erfahren: Plessner wurde als relevanter Vertreter einer Biophilosophie (wieder) entdeckt, die nicht nur die uberkommene Trennung von Natur und Kultur, sondern auch die Gegenuberstellung disjunkter Wissenschaftskulturen in Frage stellt und ihr Verhaltnis neu bestimmt. DAs Buch nimmt die verschiedenen disziplinaren Faden auf, die die Konzeption von Plessners Biophilosophie insbesondere in den Stufen des Organischen und der Mensch (1928) verstandlich machen. ES stellt Plessners uberlegungen im Kontext von naturwissenschaftlichen (von Uexkull, (...) Buytendijk, Driesch, von Weizsacker, Portmann, Kohler) sowie philosophischen (Bergson, Misch, Hartmann, Scheler, Heidegger, Jonas) Theorien seiner Zeit vor. (shrink)

Sociologue et philosophe, Georg Simmel (1858-1918) fut sans aucun doute une des grandes figures de la transition socioculturelle de cette fin de siècle, face au désenchantement de cette époque où le développement technique a pris une telle ampleur que l'homme s'est senti écrasé par ses propres créations. Simmel s'est proclamé pour un renouveau dans la culture, "une spiritualité de la vie matérielle et une matérialisation de la vie spirituelle". Cette nouvelle orientation permet à l'homme de donner un sens et un (...) but à sa vie tout en gardant une unité entre l'objectivité et la subjectivité. L'objectif de cet ouvrage est de montrer l'actualité et la fécondité des analyses simmeliennes qui nous engagent à explorer la complexité des relations individu/société. Cette nouvelle thématique socio-philosophique concerne tous les domaines, aussi bien philosophiques, qu'artistiques et religieux. Simmel ne prétendait pas fonder une école, ni former des disciples, son but ultime fut d'élever la réalité sociale du présent vers un processus culturel allant du sujet vers l'objet et réciproquement. Dans son journal posthume, Simmel compare son oeuvre à de l'argent dont chacun peut s'approprier une partie qui lui servira pour ses propres recherches. La pensée simmelienne est une mine de richesse pour l'exploration de la société et de la culture et porte en elle les germes de la modernité. (shrink)
