An Experiment on the Effects of Embeddedness in Trust Situations

Vincent Buskens
This vignette experiment was designed to study the effects of temporal embeddedness and network embeddedness in trust situations. The experiment uses a setting in which a buyer wants to buy a used car from a car dealer. We distinguish between effects on trust of the past relation and the effects of the expected future relation between the buyer and the dealer. A buyer can learn about the trustworthiness of the dealer from past transactions of...

Consensual punishment does not promote cooperation in the six-person prisoner’s dilemma game with noisy public monitoring

Nynke van Miltenburg
We study the effects of different punishment institutions on cooperation in a six-person prisoner’s dilemma game in which actors observe others’ cooperation with some noise (i.e. imperfect public monitoring). In the presence of noise, co-operators will sometimes be mistaken for defectors and punished, and defectors will sometimes be mistaken for co-operators and escape punishment. Both types of mistakes are detrimental for cooperation because cooperation is discouraged and defection is encouraged. By means of a laboratory...

Network entrepreneurial personality, network constraint and social learning: An experimental test of Burt’s theory

Charlotte Rutten
These data where gathered to study causal assumptions of Burt’s social network theory. The first assumption that was studied is the assumption that actors with stronger network entrepreneurial personalities more actively pursue a strategic network position of low constraint compared to actors with weaker network entrepreneurial personalities. The second assumption that was studied is whether being in a lower network constraint position leads to more success in advantageous decision making via social learning. What is...

Testosterone Administration and Strategic Gambling in Poker Play

Geert-Jan Will & Vincent Buskens
Testosterone has been associated with economically egoistic and materialistic behaviors, but -defensibly driven by reputable status seeking- also with economically fair, generous and cooperative behaviors. Problematically, social status and economic resources are inextricably intertwined in humans, thus testosterone’s primal motives are concealed. We critically addressed this issue by performing a placebo-controlled single-dose testosterone administration in young women, who played a game of bluff poker wherein concerns for status and resources collide. We created a computerized...

Trust in triads: An experimental study

Vincent Buskens
Pairs of trustors play finitely repeated Trust Games with the same trustee in a laboratory experiment. We study trustfulness of the trustor and trustworthiness of the trustee. We distinguish between learning and control effects on behavior. Learning effects are related to the trustor’s information on past behavior of the trustee. Control effects are related to the trustor’s opportunities for sanctioning a trustee in future interactions. The design of the experiment, with respect to trustfulness, allows...

Large-scale biaxial experiments on gypsum-gouge faults and a bare PMMA fault: Mechanical data and selected strain and image data

Loes Buijze
Geodetic observations and large-scale laboratory experiments show that seismic instability is preceded by slow slip within a finite nucleation zone. In laboratory experiments rupture nucleation is studied mostly using bare (rock) interfaces, whereas upper crustal faults are typically filled with gouge. To investigate effects of gouge on nucleation, we performed a biaxial shearing experiment on a 350 mm long saw-cut fault filled with gypsum gouge, at room temperature and σ2 = 0.3 - 5 MPa....

Frictional healing data from direct shear slide-hold-slide experiments performed on simulated fault gouges from the Groningen gas field

Luuk Bernd Hunfeld
We investigated the frictional strength recovery (healing) and subsequent reactivation and slip-weakening behaviour of simulated fault gouges derived from key stratigraphic units in the seismogenic Groningen gas field (N.E. Netherlands). Direct-shear, Slide-Hold-Slide (SHS) experiments were performed at in-situ conditions of 100 °C, 40 MPa effective normal stress and 10-15 MPa pore fluid pressure (synthetic formation brine). Sheared gouges were allowed to heal for periods up to 100 days before subsequent re-shearing. The initial coefficient of...

Dataset - Complicated Grief following Job Loss - Risk factors for its development and maintenance

J.H.W. Van Eersel
Abstract Increasing evidence shows that job loss can lead to symptoms of complicated grief (CG). However, little is known about which factors relate to the development and maintenance of CG symptoms following job loss. This study aimed to examine risk factors for the development and maintenance of job loss-related CG symptoms. For this study 485 Dutch workers who had lost their job were recruited (239 men and 246 women), with an average age of 50.2...

Frictional slip weakening and shear-enhanced crystallinity in simulated coal fault gouges at subseismic slip rates

Jinfeng Liu & Luuk Bernd Hunfeld
We report seven velocity stepping (VS) and one slide-hold-slide (SHS) friction experiments performed on simulated fault gouges prepared from bituminous coal, collected from the upper Silesian Basin of Poland. These experiments were performed at 25-45 MPa effective normal stress and 100 ℃, employing sliding velocities of 0.1-100 μm/s, using a conventional triaxial apparatus plus direct shear assembly. All samples showed marked slip weakening behaviour at shear displacements beyond ~1-2 mm, from a peak friction coefficient...
