There is a claim that clinical ethics support services (CESS) improve healthcare quality within healthcare organisations. However, there is lack of strong evidence supporting this claim. Rather, the current focus is on the quality of CESS themselves or on individual learning outcomes. In response, this article proposes a theoretical framework leading to empirical hypotheses that describe the relationship between a specific type of CESS, moral case deliberation and the quality of care at the organisational level. We combine insights from the (...) literature on CESS, organisational learning and quality improvement and argue that moral case deliberation causes healthcare professionals to acquire practical wisdom. At the organisational level, where improving quality is a continuous and collective endeavour, this practical wisdom can be aggregated into morisprudence, which is an ongoing formulation of moral judgements across cases encountered within the organisation. Focusing on the development of morisprudence enables refined scrutinisation of CESS-related quality claims. (shrink)

ABSTRACT Match-fixing is a major ethical issue in sports. Although research interest in match-fixing has increased in recent years, we remain largely in the dark regarding how both betting- and non-betting-related match-fixing relate to the moral decision-making of those involved. Drawing on Rest’s theory of morality and on the perceptions of a large sample of participants in Flemish sports, this study indicates that most match-fixing incidents are non-betting-related, while moral motivation and associated challenges clearly differ according to the type of (...) match-fixing. Therefore, each type of match-fixing requires different preventive measures. (shrink)

Dynamic Epistemic Logic This article tells the story of the rise of dynamic epistemic logic, which began with epistemic logic, the logic of knowledge, in the 1960s. Then, in the late 1980s, came dynamic epistemic logic, the logic of change of knowledge. Much of it was motivated by puzzles and paradoxes. The number … Continue reading Dynamic Epistemic Logic →.

Dit artikel is, samen met een nog volgend tweede, bedoeld als aanzet tot een bredere studie. Die studie zal, naar ik hoop, binnen twee jaar voltooid zijn. Ze maakt in zekere mate deel uit van een onderzoeksprogramma dat in uitvoering is aan de Faculteit der Wijsbegeerte van de Vrije Universiteit. Het is nu niet van belang de eigen plaats ervan binnen dat programma nauwkeuriger te omschrijven. Wel kan worden gezegd dat de studie een sterk historische inslag heeft, maar uitmondt in (...) een meer persoonlijke, systematische beschouwing. Dat artikelen met dit thema een plaats krijgen in Philosophia Reformata, behoeft waarschijnlijk weinig betoog. Een tijdschrift dat ontstaan is uit een herbezinning op reikwijdte en functie van “rede”, een herbezinning die ertoe leidde “liefde” als dieptemotief in de werkelijkheid te honoreren, —zo’n tijdschrift lijkt geen ongeschikte plek.

Diverse omstandigheden hebben het schrijven en verschijnen van het in jaargang 62, nr. 2 aangekondigde slotartikel vertraagd. Ook toen al uitte ik het voornemen de vier denkers die in het tweede artikel besproken waren nog even te groeperen. Zo’n korte groepering lijkt nu, na meer dan twee jaar, des te meer wenselijk. De vier besproken filosofen waren allen, zij het op uiteenlopende wijze, op zoek naar een nieuwe bepaling van de verhoudingen, — niet alleen tussen “Leidenschaft” en “Vernunft”, maar ook (...) tussen “Leidenschaft” als in-zet — meer actief — en als “passio”, in de zin van “lijden”.

Approximately three decades ago the question was first answered whether parasitoids are able to assess the number or origin of eggs in a host for a solitary parasitoid, Leptopilina heterotoma, by fitting theoretically derived distributions to empirical ones. We extend the set of different theoretically postulated distributions of eggs among hosts by combining searching modes and abilities in assessing host quality. In the models, parasitoids search either randomly (Poisson) (1) or by vibrotaxis (Negative Binomial) (2). Parasitoids are: (a) assumed to (...) treat all hosts equally, (b) able to distinguish them in unparasitised and parasitised hosts only, (c) able to distinguish them by the number of eggs they contained, or (d) able to recognise their own eggs. Mathematically tractable combinations of searching mode (1 and 2) and abilities (a,b,c,d) result in seven different models (M1a, M1b, M1c, M1d, M2a, M2b and M2c). These models have been simulated for a varying number of searching parasitoids and various mean numbers of eggs per host. Each resulting distribution is fitted to all theoretical models. The model with the minimum Akaike's information criterion (AIC) is chosen as the best fitting for each simulated distribution. We thus investigate the power of the AIC and for each distribution with a specified mean number of eggs per host we derive a frequency distribution for classification.Firstly, we discuss the simulations of models including random search (M1a, M1b, M1c and M1d). For M1a, M1c and M1d the simulated distributions are correctly classified in at least 70% of all cases. However, in a few cases model M1b is only properly classified for intermediate mean values of eggs per host. The models including vibrotaxis as searching behaviour (M2a, M2b and M2c) cannot be distinguished from those with random search if the mean number of eggs per host is low. Among the models incorporating vibrotaxis the three abilities are detected analogously as in models with random search. (shrink)

A review is given on statistical and modelling issues in ecotoxicology. The issues discussed are:1. How to estimate an (almost) no effect concentration chemicals in the laboratory.

The differential field of transseries extends the field of real Laurent series and occurs in various contexts: asymptotic expansions, analytic vector fields, and o-minimal structures, to name a few. We give an overview of the algebraic and model-theoretic aspects of this differential field and report on our efforts to understand its elementary theory.

Dynamic Epistemic Logic is the logic of knowledge change. This book provides various logics to support such formal specifications, including proof systems. Concrete examples and epistemic puzzles enliven the exposition. The book also offers exercises with answers. It is suitable for graduate courses in logic. Many examples, exercises, and thorough completeness proofs and expressivity results are included. A companion web page offers slides for lecturers and exams for further practice.

Fitch showed that not every true proposition can be known in due time; in other words, that not every proposition is knowable. Moore showed that certain propositions cannot be consistently believed. A more recent dynamic phrasing of Moore-sentences is that not all propositions are known after their announcement, i.e., not every proposition is successful. Fitch's and Moore's results are related, as they equally apply to standard notions of knowledge and belief (S 5 and KD45, respectively). If we interpret ‘successful’ as (...) ‘known after its announcement’ and ‘knowable’ as ‘known after some announcement’, successful implies knowable. Knowable does not imply successful: there is a proposition ϕ that is not known after its announcement but there is another announcement after which ϕ is known. We show that all propositions are knowable in the more general sense that for each proposition, it can become known or its negation can become known. We can get to know whether it is true: ◊(Kϕ ∨ K¬ϕ). This result comes at a price. We cannot get to know whether the proposition was true. This restricts the philosophical relevance of interpreting ‘knowable’ as ‘known after an announcement’. (shrink)
