The aim of this study is to investigate students’ conceptions about proof in mathematics and mathematics teaching. A five‐point Likert‐type questionnaire was administered in order to gather data. The sample of the study included 33 first‐year secondary school mathematics students . The data collected were analysed and interpreted using the methods of qualitative and quantitative analysis. The results have revealed that the students think that mathematical proof has an important place in mathematics and mathematics education. The students’ studying methods for (...) exams based on imitative reasoning which can be described as a type of reasoning built on copying proof, for example, by looking at a textbook or course notes proof or through remembering a proof algorithm. Moreover, they addressed to the differences between mathematics taught in high school and university as the main cause of their difficulties in proof and proving. (shrink)

This paper argues that a certain type of self-referential sentence falsifies the widespread assumption that a declarative sentence's meaning is identical to its truth condition. It then argues that this problem cannot be assimilated to certain other problems that the assumption in question is independently known to face.

An anti-dispositionalist interpretation of grammatical knowledge would maintain that such knowledge exists whether or not it can be behaviourally manifested; a dispositionalist interpretation, on the other hand, would identify that knowledge with the in principle possibility of certain behavioural manifestations. The purpose of this paper is to present a preliminary case for the dispositionalist interpretation by accomplishing two complementary tasks: first, rejecting a prominent argument against the dispositionalist interpretation; second, advancing an original argument against the anti-dispositionalist interpretation. Both tasks involve (...) rebuttals of certain key theses associated with Chomskyan grammatical metatheory, and therefore, provide new opportunities for assessing its viability. -/- . (shrink)

Timothy Williamson has argued that, unless the speech act of assertion were supposed to be governed by his so-called Knowledge Rule, one could not explain why sentences of the form "A and I do not know that A" are unassertable. This paper advances three objections against that argument, of which the first two aim to show that, even assuming that Williamson's explanandum has been properly circumscribed, his explanation would not be correct, and the third aims to show that his explanandum (...) has not been properly circumscribed.

We consider a new fragment of first-order logic with two variables. This logic is defined over interval structures. It constitutes unary predicates, a binary predicate and a function symbol. Considering such a fragment of first-order logic is motivated by defining a general framework for event-based interval temporal logics. In this paper, we present a sound, complete and terminating decision procedure for this logic. We show that the logic is decidable, and provide a NEXPTIME complexity bound for satisfiability. This result shows (...) that even a simple decidable fragment of first-order logic has NEXPTIME complexity. (shrink)

Foundations of Speech Act Theoryoffers a timely, thorough and, above all, compelling examination of the complexities of illocutionary acts, performatives, and their phenomenological basis. Savas Tsohatzidis has collected an impressive range of international scholars on the subject. Clearly demonstrating the relevance of speech act theory to semantic theory, the collection further interrogates the inability of pragmatic theories of illocution to properly locate such speech acts within the logic of phenomenology and intersubjectivity.

Organizational leaders are eager to unlock the creative potential of followers. Yet, there is growing evidence that creativity can also have a dark side within organizations. Building on research linking creativity and unethical behavior, we develop the construct of creative unethicality—behavior that is both unethical and novel. We draw on social exchange theory to develop a model that identifies both why and when creative unethicality emerges within organizations. Specifically, we investigate the exchange dynamics through which creative support provided by empowering (...) leaders facilitates creative unethicality under conditions of high performance pressure. Across two multi-wave, multi-source field studies with employee-coworker and leader-subordinate dyads and an experimental study with a novel unethicality measure in a business simulation, we find convergent support for our theoretical model. These findings have important theoretical and practical implications for fostering creativity in organizations without simultaneously facilitating creative unethicality. (shrink)

As we know, the Fifteenth World Congress of Philosophy has as its general theme problems of science, technology, and man. Any aspect of this all-encompassing theme produces many questions. Our task is to single out certain important aspects in it.

This paper examines, and rejects, a recent argument to the effect that knowledge is not truth-entailing, i.e. that “know” is not factive.

A problem is raised for the introduction rules proposed in Benjamin Schnieder’s ‘A logic for “because”’, arising in connection with (a) inferences that the rules should not, but do, validate and (b) inferences that the rules should, but do not, validate.

A significant body of research has emerged in order to better understand unethical behavior at work and how gender plays a role in the process. In this study, we look to add to this literature by exploring how perpetrator gender influences reactions to distinct types of unethicality. Rather than viewing unethical behavior as a unitary construct, where all forms of lying, cheating, and stealing are the same, we integrate theories and concepts from the criminal justice and moral psychology literatures to (...) categorize certain unethical behaviors as either impulsive or premeditated. Given the agentic nature of premeditated unethical behavior, we draw from role congruity theory to predict that women will be punished more severely than men for their role incongruous actions. Impulsive unethical behavior, on the other hand, will be less likely to elicit perceptions of congruity or incongruity, leading to less of a gender effect. Results from three studies sampling both undergraduates and working adults in the United States, Singapore, and South Korea showed that participants were more likely to associate premeditated unethical behavior with a male perpetrator because it was seen as less feminine, and female perpetrators who engaged in premeditated unethical behavior received more severe punishment than male perpetrators due to the perceived role incongruity of their actions. Implications are discussed as well as possible limitations and directions for future research. (shrink)

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that (...) a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.
