|| (2015-01-01) The role of epigenetic mechanisms in the programming by early-life stress and nutrition in Alzheimer’s disease|
Alzheimer’s disease (AD) is a very debilitating disease and the most common form of dementia. Age is the greatest risk factor for the development of AD. Because of the ageing trend of populations western societies the costs will significantly increase which may jeopardize the sustainability of the current health care resources. Therefore research into the etiology, diagnosis and treatment of AD is needed. Although certain genes have been found that are involved in AD they do not explain the et....................

The present paper is based on the premises that command responsibility (CR) is not a static concept, but can be better characterised as having a stable foundation in International Humanitarian Law (IHL), which has in turn continuously been applied in a creative fashion by courts worldwide in order to adapt to the ever changing nature of armed conflict. The mutual reinforcement and interconnection between IHL and International Criminal Law (ICL) in the light of contemporary warfare represent the ....................

Conflict and non-cooperative behavior can be primarily decomposed into two primal psychological states: greed, and fear. These two psychological states are associated with a variety of physiological phenomena, including hormonal fluctuations. The present
research tested whether cortisol (C) and testosterone (T) can be used as endocrinological indices of economic greed and fear and furthermore if the relationships are directional and/or reinforcing. To examine how T, C, and the interplay of T an....................
|| (2015-01-01) On the dimensionality of neural representations|
The brain is organized anatomically and functionally at dierent scales, from ensembles of neurons within cortical columns to interacting regions in networks spanning the entire brain. Multivariate pattern analysis (MVPA) is an increasingly popular method to investigate how information is represented neurally, but little is known how information is represented at these dierent
levels of organization in the brain. Often, MVPA studies restrict their analyses to local patterns of voxels, thus assum....................
|| (2015-01-01) The acquisition of avoidance tendencies towards conditioned fear cues|
We investigated how approach-avoidance tendencies towards conditioned fear cues are acquired. Participants underwent a differential Pavlovian fear conditioning procedure, during which the picture of an initially neutral cue (e.g., a cube; CS+) was always followed by a loud noise (US) whereas the picture of another initially neutral cue (e.g., a cylinder; CS-) was never followed by the US. Participants were asked to learn when to expect the US (CS-US contingency) while standing on a Nintendo WII ....................
|| (2015-01-01) Interventions for children and adolescents with Posttraumatic Stress Disorder : a meta-analysis|
The aim of this study was to determine the efficacy of psychological and psychopharmacological interventions for children suffering primarily from posttraumatic stress disorder (PTSD). A search using the databases Medline, PsycINFO, and PILOTS was conducted in which only randomised controlled trials (RCTs) were included. The search resulted in 40 RCTs, of which 48 experimental conditions and 35 control conditions met inclusion criteria. Only two of the experimental conditions were psychopharmaco....................
|| (2015-01-01) Welke executieve functies spelen een belangrijke rol bij de ontwikkeling van hypothesen toetsen?|
Kinderen tussen de 4 en 12 jaar blijken moeite te hebben met het bedenken en toetsen van hypothesen. Er zijn ook grote individuele verschillen te vinden onder de kinderen. In dit onderzoek wordt gekeken of de ontwikkeling van specifieke executieve functies bij een jong kind als een verklaring kan dienen voor het ervaren moeite met hypotheses toetsen. Er werd bij 92 kinderen een categorisatie leertaak afgenomen. Tevens zijn de executieve functies inhibitie, werkgeheugenspan en cognitieve flexibil....................

Giffin, Michael Rojek
In recent years there has been a surge of enthusiasm from both the scientific community and the general public surrounding transcranial direct current stimulation (tDCS). tDCS is a method of
non-invasive neurostimulation, and tDCS devices are available for purchase to anyone willing to spend the money. Individuals habitually using commercially available tDCS devices make seemingly utopian claims about the miraculous cognitive enhancements that tDCS can induce.
While many claims regarding these....................

The majority of patients who have lost a limb as a consequence of a trauma or after surgical removal experiences sensations in the amputated body part. These sensations can be painful in nature and
can have major impact on the quality of life. This review article aims to estimate the incidence of phantom limb pain, summarizes the current literature about its etiology and pathophysiology, and reviews the perioperative treatment strategies aimed at its prevention. Mechanisms underlying the genera....................

Viteri Vela, M.F.
Ecuador makes use of the concepts of Buen Vivir and Sumak Kawsay as alternatives to development. Regardless of their similarities, the concepts represent diverging approaches in Ecuador – Buen Vivir through policy and planning strategies by the national government, and Sumak Kawsay by the indigenous nationalities based on their
traditional values and principles. However, each concept encounters challenges in its implementation, be it through a change in their meaning as is the case of Buen Vi....................
|| (2015-01-01) Ethnic labour market discrimination and how ‘Moroccan‘ and ‘Surinamese-Hindustani’ Dutch can compensate for ethnic penalties|
Ent, B. van der
Recent research in The Hague (the Netherlands) has shown that ‘Moroccan’ and ‘Surinamese-Hindustani’ Dutch face ethnic labour market discrimination compared to ‘autochthonous’ Dutch. However, they both can counter this discrimination in different ways. ‘Moroccan’ Dutch can compensate for the ethnic penalty by having more work experience than ‘autochthonous’ Dutch. ‘Surinamese-Hindustani’ Dutch can compensate by stressing their integration into Dutch society (Andriessen et....................
|| (2015-01-01) Attention bias modificatie training : een nieuwe behandeling voor insomnie?|
Insomnie heeft grote negatieve consequenties, waardoor de kwaliteit van leven aanzienlijk verminderd. Attention bias lijkt een rol te spelen in insomnie. In deze studie werd onderzocht of een online attention bias modificatie training (ABM training) attention bias en insomnie symptomen verminderde t.o.v. een placebo training. De deelnemers werden dubbelblind gerandomiseerd in een experimentele (n=54) en placebo (n=60) conditie. De deelnemers in de experimentele conditie kregen de ABM training en....................
|| (2015-01-01) The influence of exaggerating facial expressions on subjective emotional experience|
Exaggeration as an emotion regulation strategy has been studied less often than other emotion regulation strategies. What is known now is that exaggerating positive emotions seems to heighten positive affect, but exaggerating negative emotions seems to have no influence on negative affect. The present study examined whether exaggeration is an effective emotion regulation strategy to heighten the subjective emotional experience of amusement and disgust. A sample of 52 participants watched two fil....................
|| (2015-01-01) An exploratory meta-analysis of publication bias in meta-analyses published in Psychological Bulletin|
The tendency to publish studies with significant results far more often than studies with non-significant results is called publication bias and threatens the validity of scientific disciplines. Even though there is sufficient reason to believe psychology is affected by publication bias, it has only scarcely been examined within our discipline. The present research therefore examined if publication bias is present within a collection of psychological meta-analyses and to what extent. Additionall....................
|| (2015-01-01) De invloed van hechtingsstijl op de relatie tussen type trauma en acute PTSS klachten|
In dit onderzoek stond de invloed van hechtingsstijl op de relatie tussen type trauma en PTSS klachten centraal. De 105 deelnemers hadden recent een traumatische gebeurtenis meegemaakt. Een ‘single item question’ maakte duidelijk of er sprake was van interpersoonlijk of niet-interpersoonlijk trauma. De Clinician-Administered PTSD scale (CAPS) werd afgenomen om de ernst van de PTSS klachten te meten. Deelnemers vulden zelf de Experiences in Close Relationships (ECR) in om hechtingsstijl te me....................
|| (2015-01-01) Parochial cooperation is motivated by threat to the in-group rather than intergroup conflict|
Much of human life takes place in groups, and membership in strong and successful groups allows us to achieve economic, political, and social goals. It is likely that humans are evolutionarily adapted for life in cooperative groups, and to sustain their in-group against threats. Such adaptations may occur in the context of group augmentation and bounded generalised reciprocity. While it has frequently been proposed that intergroup conflict promotes in-group
favouritism and group-bounded coopera....................
|| (2015-01-01) Civil disturbances : the limits of legally invoking a public emergency to derogate from human rights|
Beek, A.M. van
It has long been recognized in international law that human rights may justifiably be restricted in the exceptional situation of a public emergency (art. 4 ICCPR). Although it is thus clear that a State can derogate from the ICCPR as an exception, the circumstances under which it can do so are not. States have relied on article 4 ICCPR to derogate from human rights because of situations of war and environmental disasters. Political upheaval leading to (violent) civil disturbances and civil war s....................
|| (2015-01-01) Setup of optical system for laser light distribution between two atomic chip experiments|
In this thesis, a optical system is discussed that will increase the power available for lasers for one atomic physics experiment and supply laser light for an experiment currently under construction. For both experiments it will supply the light for the MOT (probe and repump) and cooling. The increased intensity for the cooling light is 200 mW, and for the optical pump 60 mW. The thesis also discusses the many
challenges that are still faced.'

Meer, Bo van der
The aim of this thesis is to analyze Heddy Honigmann and her work as a documentary maker, which has not been done before. The start of this thesis is an overview of Honigmann’s life, career and work. The thesis researches the question to what extent Honigmann can be seen as an ‘auteur’. In order to do so, it examines three documentaries as a representative sample of her complete documentary work.
The questions within the three case-studies are based on a theoretical framework that consi....................

Heijden, Sjoerd van der
This document describes the characterization of a stimulus with adjustable degree of linear polarization (DoLP) and angle of linear polarization (AoLP). This stimulus will be used to calibrate the Spectropolarimeter for Planetary EXploration (SPEX). This stimulus is a rebuild from another design . Turnable glass plates introduce a DoLP in light passing through. Using spectrometers, a rotating polarizer and dedicated software the output DoLP was determined as function of glass plate angle and ....................

The elimination of regulatory divergences between the EU and the US envisaged in TTIP would be achieved via various mechanisms of regulatory cooperation. Among the broad set of regulations that will be covered by TTIP, this thesis focuses on food safety regulatory acts – legislative acts and regulations. With a view to assessing the difficulties that TTIP would raise for the EU food safety regulatory framework, the analysis concentrates on TTIP’s SPS and TBT chapters, as well as horizontal r....................
|| (2015-01-01) Quantumgedrag van dansende oliedruppels|
Over quantumfysica wordt meestal verteld dat het vreemd en onbegrijpelijk is. Het zou zich slechts in de quantumwereld afspelen en niet na te bootsen zijn in de macroscopische wereld. Inmiddels zijn er enkele klassiekmechanische experimenten uitgevoerd die sterke gelijkenissen met de quantumfysische waarschijnlijkheidsfunctie vertonen. Uit het dubbele spleet experiment met elektronen kan bijvoorbeeld geconcludeerd worden dat deze naast dat ze beschouwd worden als deeltjes ook een golfkarakter mo....................

A system was developed for imaging of behavior and neural activity of multiple neurons simultaneously in freely moving Caenorhabditis elegans. Due to the low magnification, high numerical aperture objective (10X/0.45NA), combined with a high resolution sCMOS
camera we are able to get the entire worm in the field of view as well as resolve individual neurons spaced 2-3 microns apart. Neural activity is recorded optically using a ratiometric measurement between a calcium sensor, GCaMP3, and fluor....................

A study is done about measuring materials by inductive sensing with the LDC1000EVM sensor from Texas Instruments Inc. Wood, cardboard, and foils of brass, copper, stainless steel and aluminium are tested. Only measurements of metals can be used quantitatively. This has been concluded by comparing the measurements with a theoretic model by Dodd
& Deeds (1968), which predicts the impedance change caused by eddy currents. This suggests the use of inductive sensing in the future for e.g. measuring ....................

Pronk, Pieter Rens
One dimensional metallic systems are predicted to show exotic physics like spin-charge separation. One way to experimentally access such systems is by self-assembling growth of metallic atoms into nanowires on semiconductor substrates. In this project, highly ordered germanium surfaces were prepared and used as a template for the generation of well-separated gold nanowires with lengths exceeding 100nm. Germanium surfaces were cleaned by argon bombardment and ash annealing in ultra-high vacuum b....................

Vries, Martijn de
We present a new, robust method to estimate the energy released by AGN outbursts in clusters of galaxies. The energy released in such systems can have a huge impact on the surrounding environment and precise estimates for the amount of energy released are crucial to understanding how AGN feedback shapes the properties of galaxies and
clusters of galaxies. Typically these energies are estimated by measuring the enthalpy contained in cavities observed in the X-ray and believed to be created by th....................

Statelessness is a great issue when it comes to enjoying the human rights a person has. This essay focuses on the efforts in international law to prevent and reducing statelessness. It sees that these efforts are not enough to effectively reduce and prevent statelessness. Stateless people may be prevented from owning property, renting an apartment but also education and employment may be dreams but never a reality. As human rights are founded on the principle of universality the lack of national....................

|| (2015-01-01) Financial (un)Fair Play : analysis of UEFA's Financial Fair Play Regulation in light of European Union competition law|
Due to the rise in transfer fees and the increase of player salaries, European football clubs are forced to increase their spending. This increase goes hand in hand with financially risqué behavior. This does not only endanger the financial stability of the football clubs, but also of the European football market as a whole.
In order to protect the financial stability of the European football market, UEFA introduced the Financial Fair Play Regulation. The core element of this regulation holds ....................
