Show moreThe debate on free will is dominated by the discussion between compatibilists and incompatibilists. The central intuition of the incompatibilist is that the future must be open; on the other hand, for the compatibilist it makes no difference to free will whether or not the laws of nature are deterministic. This paper argues that we can hold the incompatiblist and compatibilist intuitions together with the doctrine of free will, on the condition that we deny the seemingly evident claim that determinism implies a closed future. In order to deny this claim, I develop a new version of presentism that I call causal presentism. The causal presentist holds that only the present exists, and that statements about the past and the future are statements about what the present causally implies. Within this framework, the open future and determinism are compatible so long as we are willing to accept that our present choices determine not just the future, but also the past. I discuss several counterarguments that can be brought against this idea, showing that they lack force. In doing so, I demonstrate that causal presentism is worthy of further development. Show less

Show moreEtiological research aims to uncover causal effects, whilst prediction research aims to forecast an outcome with the best accuracy. Causal and prediction research usually require different methods, and yet their findings may get conflated when reported and interpreted. The aim of the current study is to quantify the frequency of conflation between etiological and prediction research, to discuss common underlying mistakes and provide recommendations on how to avoid these. Observational cohort studies published in January 2018 in the top-ranked journals of six distinct medical fields (Cardiology, Clinical Epidemiology, Clinical Neurology, General and Internal Medicine, Nephrology and Surgery) were included for the current scoping review. Data on conflation was extracted through signaling questions. In total, 180 studies were included. Overall, 26% (n = 46) contained conflation between etiology and prediction. The frequency of conflation varied across medical field and journal impact factor. From the causal studies 22% was conflated, mainly due to the selection of covariates based on their ability to predict without taking the causal structure into account. Within prediction studies 38% was conflated, the most frequent reason was a causal interpretation of covariates included in a prediction model. Conflation of etiology and prediction is a common methodological error in observational medical research and more frequent in prediction studies. As this may lead to biased estimations and erroneous conclusions, researchers must be careful when designing, interpreting and disseminating their research to ensure this conflation is avoided.

Show moreHet Europese non-foodproductveiligheidsrecht bevat productnormen die veelal als publiekrechtelijk worden bestempeld. Bij de harmonisatie gebruikt de Europese wetgever verschillende soorten productnormen, namelijk bindende eisen in richtlijnen en verordeningen en niet-bindende Europese normalisatienormen. De literatuur neemt aan dat Europese productnormen ook invloed kunnen hebben op de privaatrechtelijke normen die gelden in rechtsverhoudingen tussen bijvoorbeeld de eindgebruiker van het product en andere partijen in de handelsketen, alsmede tussen concurrenten. Dit onderzoek beantwoordt de vraag wat de exacte betekenis is van Europese productnormen voor privaatrechtelijke normstelling. Wanneer is een productnorm slechts een van de relevante omstandigheden van het geval bij de formulering van een privaatrechtelijke norm? Wanneer vult een productnorm een privaatrechtelijke norm grotendeels in, in de zin dat de productnorm het uitgangspunt vormt? Van welke omstandigheden en factoren is deze betekenis afhankelijk?Het onderzoek biedt de lezer een nadere introductie in het wat onderbelichte Europese productveiligheidsrecht en beantwoordt de hoofdvraag aan de hand van een Europeesrechtelijk, institutioneel en privaatrechtelijk perspectief. De privaatrechtelijke analyse ziet op de belangrijkste Nederlandse rechtsgronden voor doorwerking van productnormen en bevat rechtsvergelijking met het Engelse en Duitse recht. Bovendien vindt een uitvoerige analyse van Nederlandse feitenrechtspraak plaats om te zien hoe feitenrechters in de praktijk met productnormen bij de invulling van privaatrechtelijke normen omgaan. Het onderzoek besluit met een overzicht van gezichtspunten die behulpzaam kunnen zijn bij het beoordelen van de betekenis van productnormen voor privaatrechtelijke normstelling in concrete gevallen.

Show moreIn this thesis, we aimed to better understand how genetic variation affect the processes underlying health and disease, as trait-associated genetic variants are often located in non-coding regions. This hampers their interpretability, and has prompted the exploration of their effects on transcriptional regulation, a process that is crucial in the development of common and complex diseases. To do this, we have used a variety of omics data in a large collection of individuals from the general population. Using these data, we have investigated the local and distal effects of genetic variants on other molecular phenotypes, such as gene expression levels and DNA methylation levels of CpG sites, and the underlying mechanisms. This has resulted in a framework enabling the exploration of causal hypotheses about transcriptional regulation using genetics as a causal anchor. The approaches used in this thesis have yielded insight into transcriptional (dys)regulation and several underlying mechanisms. This will be helpful in better understanding how transcriptional regulation contributes to complex phenotypes related to health and disease, such as common diseases. Show less

Show moreThe author addresses a recent force employment concept called effects-based operations, which first appeared during the 1991 war against Iraq. The attributes of effects-based operations can be grouped around three common, but interrelated elements such as effects focus, advanced technology, and systems thinking. However, the characteristics upon which the common elements are built, such as causality/deduction for effects focus, intangibles/control for advanced technology, and categorisation/analysis for systems thinking bear dangerous simplifications regarding the nature of war. These characterictics are in sharp contrast with war__s frictional nature as outlined by Clausewitz, who stated that effects in war cannot be traced back to single causes, as several concurrent causes are normally at work. Novelty must always be expected in war as friction dims expectations in terms of causality and the ability to achieve desired effects. The author suggests an organic approach to address the challenge posed by war. According to him the emphasis must shift towards learning and adaptation, instead of planning for desired effects. Friction indicates that often it is more important in war how we do things than what things we do, which has a clear practical limitation for the concept of effects-based operations. Show less

Show moreThe central topic of the Thesis concerns light scattering experiments with entangled photons. Specifically, we study the effect of scattering processes on polarization-entanglement of twin-photons. The main idea is that scattering generally couples polarization and spatial degrees of freedom of photons. The details of this coupling depend on the characteristics of the scattering medium. Such coupling, in turn, can reduce the entanglement of twin-photons, if the photon pairs are detected in a momentum-insensitive way. We have investigated a broad range of optical scattering media ranging from milk to polymer fibers. By manipulating the parameters of these samples we were able to generate a broad range of quantum states, proving for the first time that scattering processes are a substantial tool for mixed-state engineering. This is of great importance for quantum information since any real-world application thereof has to deal with mixed (as opposed to pure) states. Show less
