Empowerment though Indignation

Hannah Nonnenberg
This research investigates activists of the Indignados movement in Spain. It identifies and explores what empowerment mechanisms said activists use in order to overcome alienation. Alienation is the condition they are in, which is greatly shaped by globalization and the Spanish economic crisis. The name chosen by the movement ‘indignados’, meaning indignation, is the reason for the present focus on emotions in academic research on social movements. The movement finds itself in an alienated context,...

Using Program Dependency Graphs for plagiarism detection in Python

Thomas Schaper
Plagiarism in computer science education programs is a significant problem, requiring resilient, reliable, automated tools for efficient detection. Plagiarism detection tools based on Program Dependency Graphs (PDG) fulfill these requirements, but do not directly support all programming languages. For example, for Python, an increasingly popular programming languages in computer science education, traditional PDG-based methods do not work, as they create too many incorrect edges. In this work we propose the PyDG framework, the first solution...

Discovering the Core of the Russian Interbank Market

Marije Sluiskes
This paper investigates to what extent the structure of the Russian interbank market over the period 1998-2004 can be described by applying the core-periphery model as defined by Craig and von Peter (2014), using a greedy algorithm. It finds that the fit is significant, although the error score of 54 percent is relatively high compared to earlier studies which applied this core-periphery model to more mature interbank markets. Additionally, this paper finds that the fit...

Structural characterization and activation of nature’s fuels of life

Rianne Van Outersterp
Hydrolysis of nucleotide triphosphates (NTPs) is known to drive highly important cellular processes. Of these NTPs, adenine triphosphate (ATP) is mainly studied as it is concerned to be the central fuel of living cells. Gas-phase studies have been performed to elucidate the conformational preference of NTPs focusing on the dependence of the nucleobase and extent of deprotonation. Therefore, a combination of infrared (IR) spectroscopy and mass spectrometry has been applied to ATP, CTP and GTP....

Novel folded pendulum residual seism accelerometer for the Virgo gravitational wave observatory: parasitic resonance mode characterisation

Harun Dza
Optical components of a gravitational wave (GW) detector must both actively and passively be isolated from microseisms to be able to detect GWs. Active attenuation is achieved by making use of accelerometers within seismic isolation systems. Herein, a characterisation of the internal leg mode resonances of an improved design Folded Pendulum accelerometer, present at the Virgo GW observatory, is being discussed. We model internal leg mode resonances of the accelerometer using Finite Element Method analysis...

Maximizing the Effect of Shared Top Management Team Experience on Team Performance

Robert Kroner
This paper examines the effects of shared top management team experience on team performance. Previous literature predicts that there could be positive or negative effects caused by team stability. For top management teams, a curvilinear relationship between shared team experience and performance is being proposed, resulting in a performance peak point. An empirical study of US-based top management teams confirmed both the positive effects and the diminishing returns, implying a maximum point after 10 years....

Proximal Esophageal Cancer

Maximilian Kloft, Sandra Geurts, Margreet Van Putten & Judith De Vos-Geelen
Proximal esophageal cancer (PEC) is a highly mortal cancer with a five-year survival rate of 30%. Because second primary tumors could decrease survival in PEC patients, this research is aiming at finding out about tumors associated with PEC and their infuence on survival. With the use of a database with PEC patients, diagnosed between 1989 and 2014, it was found that head and neck cancers (H&N) are the most prevalent previous tumor in PEC patients....

De adviserende rol van pedagogisch medewerkers bij peuters met stotterverschijnselen

Ilham El Harouni
Inleiding: In de praktijk valt het op dat pedagogisch medewerkers (pm-ers) niet altijd tijdig adviseren om een stottertherapeut/ logopedist te consulteren als de stotterverschijnselen/-problemen bij een peuter opvallen. Dit kan negatieve gevolgen hebben op de ontwikkeling van de stoornis. Methode: Er is een gemengd onderzoeksdesign uitgevoerd door middel van 54 ingevulde enquêtes en twee semigestructureerde interviews. Resultaten: De huidige beschikbare informatie over stotteren is bij een groot deel van de pedagogisch medewerkers onbekend. Conclusie: Een...

Spraakverandering ten gevolge van gebitsrehabilitatie bij ernstige gebitsslijtage

Sanne Limonard & Ellen Van Sambeeck
Het effect van gebitsrehabilitatie op spraak is gemeten voor, direct na en minimaal een maand na de gebitsrehabilitatie aan de hand van een luisterexperiment en een vragenlijst. Veertig getrainde luisteraars en 40 niet getrainde luisteraars gaven een beoordeling over de spraak en de /s/ en /t/ klanken. Patiënten beoordeelden hun spraak aan de hand van een vragenlijst. Getrainde luisteraars en patiënten beoordeelden de spraak op alle tijdsmomenten gelijk. Niet getrainde luisteraars beoordeelden de spraak minimaal...

Central and Local Approaches to Transitional Justice

Julianne Subia
This paper aims to examine the relationship between central and local approaches to transitional justice in postconflict situations. It is found that these two levels are not as ‘neat’ as some may suggest, and actors from both levels behave in ways more commonly attributed to the other level. By thinking of them in dynamic and behavioral rather than static and spatial terms, the (inter)relationship might be better understood. This is important as transitional justice is...

Tricked by transparency: Security made in Europe

Iana Gein
Transparency is generally recognised as an effective policy instrument to increase accountability and fight misconduct. To further our understanding of transparency impact in arms exports, it is thus useful to investigate the EU transparency framework, and analyse the extent member states are adhering to it. This research does it by examining contribution of France, Germany, and the UK to the Annual Reports in relation to their arms exports to the Middle East during 2010-2016. The...

The Interdependence of Economic Growth, Human Development and Political Institutions

Sebastian Krantz
The causal links between growth, human development and institutions are central to understanding the long-run development process. The turn of the millennium has seen influential research in development economics attempting to uncover some of these links, but a focus on root-causes of growth has limited its insights in both scope and method. This paper provides a fresh analysis of the interdependence of growth, human development and institutions using a general equilibrium framework. The framework is...

Data peeking: a quantitative and qualitative exploration of the use of interim analysis

Mandy Woelk & Esther Klinkenberg
Data peeking, quitting data collection early or adding more participants at the end, offers the advantage of saving time and money. However, performing an interim analysis without correction leads to a Type-I error inflation. Using alpha spending function could be used to solve this problem. In this paper, we simulated the effects of interim analysis with and without an alpha spending function on type-I error, power and expected sample size. We also offer a Bayesian...

The Relation between Reading Strategies and Reading Comprehension

Elisa Korthof
Since 2009, Dutch primary school teachers have started to explicitly teach reading strategies to their students, basing themselves on findings that the use of reading strategies can benefit children’s reading comprehension. The aim of the current study was to examine how often Dutch 5th grade students (groep 7) apply reading strategies during reading, and to re-examine the relationship between reading strategies and reading comprehension. The results of this study indicate that children (N = 116)...

Bringer of Death: Explaining the Severity of the Black Death in Medieval England

Elvire Nadieh Landstra
What caused the Black Death in the 14th century to be more severe than any other plague outbreak? This article argues that the Bovine Pestilence, and the consequent protein malnutrition, has contributed to an inadequate immune system for the English population. As a result, the mortality rates during the plague outbreak were high. By using contemporary insights on the Y. Pestis bacterium and immunodeficiencies, and combining that with historical data on the Black Death in...

Beaten by the chord to nail the melody: Influence of metric and irregular submerged dissonance accents on auditory sequence learning

Anna Sophie Wagner
Dynamic attending theory (Jones, 1976; Large & Jones, 1999) suggests that isochronously repeating salient points in time are predictable and facilitate processing by synchronizing attentional oscillations in the brain. By manipulating amount and spacing of such salience, this design attempts to enhance accuracy of reproduced melodies. Salience was introduced by dissonant harmonies. All subjects seemed to get distracted by the harsh sound of dissonance. However, non-musicians seemed to benefit from a regular ¾ meter. More...

ID.alistic: identificatie met een touch voor de patiënt

Maarten Zijlmans, Marcel Wilschut & Linda Wauben
ID.alistic is een conceptuele patiëntidentificatie methode (middels een vingerafdrukscanner), ter vervanging van het polsbandjessysteem van het Albert Schweitzer ziekenhuis (ASz) dialysecentrum. Dit onderzoek bepaalt de implementeerbaarheid van ID.alistic binnen het dialysecentrum door behoefteanalyse, risicoanalyse en het testen van een prototype. Dialysepatiënten en -verpleegkundigen zien ID.alistic graag geïmplementeerd. ID.alistic draagt grotere risico’s met zich mee dan het polsbandje, alhoewel deze risico’s vermijdbaar zijn. Uit de test bleek dat een optische vingerafdrukscanner niet geschikt was, omdat de...

Are openness to trade and regional integration good for the environment?

Dang Minh Hang
Using a 26-year panel data set from 1990 to 2015, this paper aims to investigate the effects of openness to trade and regional integration among ASEAN+3 countries. With the application of fixed-effects model, trade, foreign direct investment, and regional environmental agreements beneficially affect the environment in this region, indicated by the reduction in carbon and greenhouse gas emission and forest gain. The empirical evidence supports intra-regional incentives for more trade liberalization and deep integration. Positive...

Predicting Failures of Russian Banks Using Parametric and Non-parametric Techniques

Maximilian Negele
In this paper I compare three methods to predict bank failures in the Russian banking sector. Based on data ranging from 1997 to 2004 I test the predictive performance of Random Forests and Rotation Forests and compare it to logistic regression using four different time horizons for failure. The sample size ranges between 1,960 and 10,500 and includes 9 different financial ratios as predictors. I conclude that Random Forests outperform both Rotation Forests and logistic...

Exploration of the ‘Mean World Syndrome’ in Dutch Older Persons

Lisa Klinkenberg
It was hypothesized that persons aged 57 and over who use more types of mass media, such as internet, television and newspapers, are more anxious and afraid. Also the effects of the different types of media as well as the different contents are explored. The sample originates from the Longitudinal Aging Study Amsterdam (LASA) and consists of 1536 respondents, who were assessed in 2005/2006. It was found that reading newspapers as well as internet use...

The Sound of Semana Santa

Jip Lensink
This anthropological research gives insight in the meaning of music for the religious experience of participants of the processions in Antigua, Guatemala. By placing the theories of lived religion, material religion and aesthetics at the central stage, the process whereby the marchas fúnebres, the music played in the processions, mediate religious experience for the participants is explained. The material-sensorial elements of the processions, the practice of carrying, and the emotional effect of the music which...

Feasibility study of nano plating for the visualisation of hydrogen in steels

Renee Coryn, Liesbet Deconinck & Ellen Lambrechts
Visualisation of hydrogen in metals is a very challenging topic as microscopic techniques are not yet able to visualise hydrogen atoms accurately. Several micrometre sized techniques were already developed to visualise hydrogen in a qualitative way and link it to the metal’s microstructure. However, many disadvantages still limit these techniques. Two innovative approaches have been evaluated in the present work. Both are based on the nano plating principle where a redox reaction occurs between metal...

The destruction of cultural property by the Islamic State in Mosul and Palmyra

Alessandra Silva
Among countless atrocities, the Islamic State (IS) is responsible for wreaking cultural artifacts in Mosul and Palmyra. This paper enquire what actions Iraq and Syria could undertake under International Law to protect cultural property and to hold IS’s fighters accountable for their crimes. After analyzing International Humanitarian law instruments, the rules on the use of force, the UNESCO Declaration on the Intentional Destruction of Cultural Heritage and the Statute of the International Criminal Court, it...

Het Buddy-project voor eetstoornispatiënten: een exploratief kwalitatief onderzoek naar de inzet van herstelde ervaringsdeskundigen als Buddy

Marloes Biegel
Het Buddy-project is een initiatief om eetstoornis- patiënten te ondersteunen, waarbij de patiënt één op één wordt gekoppeld aan een herstelde ervaringsdeskundige. In dit onderzoek is middels interviews, vragenlijsten en een focusgroep het perspectief van ervaringsdeskundigen en eetstoornispatiënten ten aanzien van het Buddy-project in kaart gebracht. Uit dit onderzoek blijkt dat patiënten een Buddy zien als een begripvolle, gelijkwaardige en laagdrempelige gesprekspartner, die zou kunnen ondersteunen bij het oefenen van lastige situaties, zoals samen eten,...
