In this paper Grice's requirements for assertability are imposed on the disjunction of Classical Logic. Defining material implication in terms of negation and disjunction supplemented by assertability conditions, results in the disappearance of the most important paradoxes of material implication. The resulting consequence relation displays a very strong resemblance to Schurz's conclusion-relevant consequence relation.

This paper contains different approaches to solve the problem how to construct the ultimate position out of one’s interventions in a discussion after possibly one or more position changes. In all approaches it is the aim to come as close as possible to human reasoning. Therefore all logics are adaptive logics. The first logic is an extension of an adaptive translation into S5 of the Rescher-Manor mechanisms. The second one is a dynamic proof theory based on a technique using indices. (...) In the end a satisfactory solution is given by a dynamic proof theory expressing the idea of prioritized compatibility, i.e. compatibility step by step. (shrink)

This paper is a contribution to the program of constructing formal representations of pragmatic aspects of human reasoning. We propose a formalization within the framework of Adaptive Logics of the exclusivity implicature governing the connective ‘or’.Keywords: exclusivity implicature, Adaptive Logics.

A logic of diagnosis proceeds in terms of a set of data and one or more (prioritized) sets of expectancies. In this paper we generalize the logics of diagnosis from [27] and present some alternatives. The former operate on the premises and expectancies themselves, the latter on their consequences.

This essay series attempts to stimulate the debate about the moral challenges that internationalisation confronts us with, both in the Netherlands and abroad, and in particular for Artist-in-Residencies (AIRs). The publication is a reflection on how the crisis is reconsidering our international ambitions, starting from a post-COVID society. Internationalisation is an inevitable reality, inherent to the art landscape. The current time calls for a critical reflection on major issues such as climate inequality, plurality and the Western-dominant canon. 0With contributions and (...) critical insights by Jeanne van Heeswijk, Jack Segbars, Erik Hagoort, Pascal Gielen, Cecilia Bengtsson, Merlijn Twaalfhoven, Hicham Khalidi, reinaart vanhoe and Suzanne van der Beek.

En este trabajo discuto los criterios que se han postulado para establecer una distinción entre los estados doxásticos y los subdoxásticos; a saber: accesibilidad a la conciencia, integración inferencial y conceptualización. Esta discusión se realiza a través del análisis de los argumentos propuestos por Davies. Mi tesis es que si bien habría una distinción intuitiva entre ciertas clases de estados mentales, estos criterios, según las dos lecturas posibles de lo que el mismo Davies propone para que un criterio constituya una (...) distinción de principio, no parecen establecer la distinción deseada. /// In this paper I discuss the criteria that have been postulated for a principled distinction between doxastic states and subdoxastic states, namely: accesibility to consciousness, inferential integration, and conceptualization. The discussion set off from the analysis of the arguments put forward by Davies. My claim is that although there would be an intuitive distinction among certain kinds of mental states, according to two plausible readings of what Davies himself proposes as a principled criterion, such criteria do not seem to establish it.

Emergency nurses apply specialist knowledge to the practice of emergency care. This paper discusses the ways in which three emergency nurses understand the nature of their care from their own frames of reference and experiences and presents some of the data collected in a larger study. Various discourses, which compete to inform emergency nurses' understandings of practice, are linked with the notion of nurses as subjects; that is, each discourse may inform, shape and constitute the practice of the nurse and, (...) in turn, the ways in which the patient comes to be known and understood. I will examine the ways in which emergency nurses come to experience or position themselves vis‐à‐vis extant forms of knowledge of emergency care and the extent to which they articulate new or distinctive formulations of emergency care. This paper illuminates the commonalities that constitute the discourses of emergency nursing care, and also analyse nurses' language which demonstrates that within each discourse variations, contradictions and resistances exist. Emergency nursing care occurs in a context of a biomedical discourse that dominates, or tends to dominate, the work of the emergency setting and so to determine acceptable or possible practices. Nevertheless, nurses contest in various ways the ‘truths' that they understand to underpin their practice. Challenges to biomedical discourses are revealed, to some extent, by drawing attention to specific situations and particular struggles encountered in emergency nurses' everyday practice. (shrink)

Methodologies of poststructuralist theory and critical social theory may be appropriated for nursing research and practice. Researchers using either methodology employ an analysis of power to explore experiences in various fields, and raise issues diat are highly relevant to nursing. However, the two methodologies differ and, often, die respective dieories are sharply opposed. In diis paper, die differences bodi from widiin and between each approach are explored, showing dieir tensions and limits. I contend that a reflexive approach to discourse analysis (...) provides insight into some of die methodological challenges diat arise in die context of bodi dieories. It is argued diat die differences between poststructuralism and critical social dieory seem likely to be mellowed by encounters diat treat each other with respect. To some extent, such encounters may tend to converge die two positions. (shrink)

There is little information about the content of ethics consultations in pediatrics. We sought to describe the reasons for consultation and ethical principles addressed during EC in pediatrics through retrospective review and directed content analysis of EC records at St. Jude Children's Research Hospital. Patient-based EC were highly complex and often involved evaluation of parental decision making, particularly consideration of the risks and benefits of a proposed medical intervention, and the physician's fiduciary responsibility to the patient. Nonpatient consultations provided guidance (...) in the development of institutional policies that would broadly affect patients and families. This is one of the few existing reviews of the content of pediatric EC and indicates that the distribution of ethical issues and reasons for moral distress are different than with adults. Pediatric EC often facilitates complex decision making among multiple stakeholders, and further prospective research is need.. (shrink)

This paper examines how three Dutch political parties employ the Internet as a tool to enhance ‘digital democracy’. The potential of digital democracy is considered to be strongest in the sphere of collective action outside the domain of political institutions. In this article, however, attention is given to how institutionalized channels might be supportive of digital democracy. Three components of the democratic process – information provision, deliberation, and political decision-making – are examined in the content and user assessments of the (...) web sites of the Socialist Party, the Christian Democratic Party and the Green Party. Minor differences were found in the party web sites regarding information provision; substantial differences were found regarding the degree and nature of political deliberation available on the sites. Indicators of the third component, political decision-making, were least evident on all three web sites. User assessments of the sites and opportunities for political deliberation followed, more or less, the general public images of the related political parties. (shrink)

Despite recent advances in HIV prevention and treatment, high HIV incidence persists among people who inject drugs. Difficult legal and political environments and lack of services for PWID likely contribute to high HIV incidence. Some advocates question whether any HIV prevention research is ethically justified in settings where healthcare system fails to provide basic services to PWID and where implementation of research findings is fraught with political barriers. Ethical challenges in research with PWID include concern about whether research evidence will (...) be translated into practice; concerns that research might exacerbate background risks; and ethical challenges regarding the standard of HIV prevention in research. While these questions arise in other research settings, for research with PWID, these questions are especially controversial. This paper analyses four ethical questions in determining whether research could be ethically acceptable: Can researchers ensure that research does not add to the burden of social harms and poor health experienced by PWID? Should research be conducted in settings where it is uncertain whether research findings will be translated into practice? When best practices in prevention and care are not locally available, what standard of care and prevention is ethically appropriate? Does the conduct of research in settings with oppressive policies constitute complicity? We outline specific criteria to address these four ethical challenges. We also urge researchers to join the call to action for policy change to provide proven safe and effective HIV prevention and harm reduction interventions for PWID around the world. (shrink)

Eyal et al have recently argued that researchers should consider conducting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) human challenge studies to hasten vaccine development. We have conducted (J. L.) and overseen (L. D.) human challenge studies and agree that they can be useful in developing anti-infective agents. We also agree that adults can autonomously choose to undergo risks with no prospect of direct benefit to themselves. However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, for (...) 3 reasons: (1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; (2) autonomous decision making, while necessary, does not override concerns about risk; and (3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the coronavirus disease 2019 (COVID-19) pandemic.

The ‘managed care’ idea: implications for health service systems in Australia The growth of corporatism in health‐care in the US, and the consequences arising from US models of health‐care delivery systems provide an enormously valuable point of comparison with health systems of other developed economies, such as Australia. If lessons are to be learnt from the US, then an analysis of the structure and performance of the US health‐care system provides important background for understanding and assessing contemporary policy changes to (...) administrative and organizational designs and techniques for patient care in Australia.

This article studies the conceptions of social justice of women active in transnational migrant politics over a period of roughly 20 years in the Netherlands. The novel focus on migrant women reveals that transnational politics is almost completely male-dominated and -directed. Two of the exceptions found in this article include a leftist and a Kurdish women organization supporting the communist cause in the 1980s and the Kurdish struggle in the 1990s in Turkey, respectively. In both organizations gender equality was subordinated (...) to broader ideologies of political parties in their homeland. Leftist activists in the cold war era supported a narrow definition of the "politics of redistribution," while and Kurdish activists, combined classical features of the latter with those of traditional identity politics.
