This study sought to determine cardiologists’ degrees of ethical awareness and preferred courses of action for ethical dilemmas frequently encountered in clinical settings. For this evaluation, an online survey was created and sent to cardiologists affiliated with various academic posts in Ankara, Turkey. The survey included ten cases with various ethical considerations selected from our book, “Clinic Ethics with Cases from Cardiology.” Four possible action choices were defined for each case. Participants were asked to choose one or more of these (...) preferences. In addition, a fictional change was made in each case’s context without changing the original ethical issue, and participants were asked whether an attitude different from the first chosen one was preferred. The participation ratio was 49/185 (26%), consent ratio 47/185 (25,4%), and completion ratio 44/185 (23,7%). Nine of the ten scenario changes did not change participants’ preferred action. For most questions, action preferences were concentrated between the two options. Although legal regulations did not reduce ethical dilemmas, they clarified physicians’ action preferences. Similarly, as an obscure moral issue gained prominence, physicians were forced to draw clearer lines in their actions. External factors such as healthcare emergencies can change physicians’ ethical dilemma-solving attitudes. (shrink)

BackgroundThe coronavirus disease (COVID-19) treatment must be based on scientific methods such as clinical trials. Trials involving human subjects and those requiring a risk-benefit analysis may occasionally face challenges owing to the time limitations in the pandemic. MethodologyThis study analyses the WHO's International Clinical Trials Registry Platform and clinicaltrials.gov, where most COVID-19 clinical trials are registered, according to ethical criteria including study design, conflicts of interest, enrollment of healthcare workers, study locations, site-, design-, and participant-related issues. The discussion is based (...) on three aspects: the quality of the information to be produced, the relevance to significant health problems, and the creation or evaluation of interventions, policies, or practices that promote individual or public health. ResultsThere were significant differences between the two platforms regarding the investigational medicinal product (IMP), the comparator, ethics committee/institutional review board approval, plan to share individual participant data, study phase, site, IMP, and design-related issues. Conflict of interest, sponsor information, and management of vulnerable groups were the main areas wherein both platforms lacked sufficient information. ConclusionWith this analysis, we aimed to define a minimum set of ethical criteria for clinical trial platforms to obtain standardization between these two platforms. (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.

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.

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)

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.

Several influential philosophical accounts of assertion have recently been claimed by Peter Pagin to commit a fundamental mistake. The present paper argues that Pagin's defence of that claim is flawed: The criterion he proposes for evaluating theories of assertion is unreliable; and even if it were supposed to be in itself reliable, it could not be used, in the way he proposes, either against the kinds of theories he intends to undermine or in favour of the kind of theory he (...) intends to support.

The most distinctive, and probably the most striking, assumption of Donald Davidson's well known ‘paratactic’ analysis of the logical form of saying ascriptions is that the “that”-clause that, in such an ascription, specifies the content of the ascribed act of saying, is neither syntactically nor semantically part of the sentence effecting the ascription. The present paper identifies a neglected problem that this assumption engenders for the Davidsonian analysis. The problem arises in connection with instances of saying ascriptions that are both (...) self-verifying and self-referential, and consists in the fact that, given the Davidsonian assumption, these ascriptions must be assigned logical forms that misrepresent their logically relevant properties.

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

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 is an addendum to [Tsohatzidis, 2013].

This paper intends to contribute to the evaluation of the project of analyzing speech act concepts in terms of mental state concepts, by examining Searle's and Vanderveken's proposed analyses of certain types of illocutionary acts as expressions of corresponding types of emotional states. It is argued that the proposed analyses are all defective, that the assumptions about underlying speech act/mental state parallelisms from which their initial plausibility might be taken to derive are themselves mistaken, and that the fact that they (...) have been proposed at all betrays insufficient attention to the distinction between semanti-cally and pragmatically determined aspects of utterance interpretation. It is concluded that these results disturb both the overall structure of Searle's and Vanderveken's theory of speech acts, and the logic of several other similarly reductionist claims in the philosophy of language.

This paper examines a recent attempt to provide a negative answer to the question of the existence of illocutionary negations. It argues that the attempt is unsuccessful both because it presupposes a misinterpretation of the question's theoretical import and because, even granting that misinterpretation, it bases its proposed answer on certain assumptions that can independently be shown to be untenable.
