The anthropological signification of the ‘Man with No Breath’ in Visayas and Mindanao epics
This paper explores the long-term endurance of “breath” as a schema of personhood in the Austronesian-speaking world, from a comparative-ethnographic approach to the “Man with No Breath” figure featured in Philippine epics. This is one of two contributions from Myfel D. Paluga and Andrea Malaya M.…

Digital Humanitarian Networks: Crisis Management as a Social System
Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

Evaluation and implementation of innovative diagnostics and treatment
If a new method has been developed to recognize and treat a (neuro-)psychological disorder or related behavioral factors, it cannot yet be used directly in clinical practice. First, the method should be evaluated, preferably in randomized controlled trials.

Data mining and algorithm development
Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

Controlling anxiety in late life (CALL)
Primary Objective: The primary aim of the proposed RCT is to evaluate whether LF-TLP in blended form as an indicated prevention for anxiety complaints is more (cost-) effective than TAU according to the NHG guideline Anxiety. We hypothesize that in comparison to TAU, LF-TLP will result in a significantly…

Theoretical Physics
In the spirit of 'unity in diversity', our objective is to promote insight into and appreciation for the wonder that the same physical laws and mathematical concepts apply to the whole of nature, from the largest to the smallest energy and length scales. We strive for the application of abstract theoretical…

Geometry of Vegetation Pattern
One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

Highly Accurate Simulations and Benchmarking of Molecule-Surface Reactions
Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Computational aspects of class group actions and applications to post-quantum cryptography
Most of current public-key cryptography is considered insecure against attacks from sufficiently powerful quantum computers. Post-quantum cryptography studies methods to secure information resistant against such attacks. One proposal is isogeny-based cryptography, which bases its security on computational…

From Homo Economicus to Political Animal
Who is Economic Man? Every economic paradigm presupposes an anthropology, a theory of human nature. This project explores the anthropologies presupposed and produced by ancient Greek economic texts, and the specific knowledge forms that shape these anthropologies.

Vibration Isolation
To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

Open label placebo for itch
Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…
