Trust is a good approach to explain the functioning of markets, institutions or society as a whole. It is a key element in almost every commercial transaction over time and might be one of the main explanations of economic success and development. Trust diminishes the more we perceive others to have economically different living realities. In most of the relevant contributions, scholars have ta...

A line-search method, based on retractions, is formulated on Riemannian manifolds. This Riemannian line-search method, as well as a previouslyproposed Riemannian trust-region method, are further generalized to accelerated line-search and trust-region methods, where the next iterate is allowed to be any point that produces at least as much decrease in the cost function as a fixed fraction of the...

BACKGROUND Incidents in health care happen every now and then. Incidents are often extensively covered by the news media. In this study, we investigated the impact of an incident in a Dutch hospital on public trust in health care in the population living in the vicinity of where the incident took place and in the national population. News media coverage of the incident started in Fall 2008. M...

Biobanks are made all the more valuable when the biological samples they hold can be linked to health information collected in research, electronic health records, or public health practice. Public trust in such systems that share health information for research and health care practice is understudied. Our research examines characteristics of the general public that predict trust in a health s...

Trust has been considered as a social relationship between two individuals in human society. But, as computer science and networking have succeeded in using computers to automate many tasks, the concept of trust can be generalized to cover the reliability and relationships of non-human interaction, such as, for example, information gathering and data routing. This paper investigates the evaluat...

Over the past decades, numerous twin studies have revealed moderate to high heritability estimates for individual differences in a wide range of human traits, including cognitive ability, psychiatric disorders, and personality traits. Even factors that are generally believed to be environmental in nature have been shown to be under genetic control, albeit modest. Is such heritability also prese...

We study political activism by several interest groups with private signals. When their ideological distance to the policymaker is small, a “low-trust” regime prevails: agents frequently lobby even when it is unwarranted, taking advantage of the conŽ rmation provided by others’ activism; conversely, the policymaker responds only to generalized pressure. When ideological distance is large, a “hi...
