This paper written by Vydra and Kantorowicz answers the research question ‘What policy-relevant information does Twitter contain?’ as well as the research question ‘How does this information change between a period of normalcy and a period of crisis?’

How did the slave peculium function in the socio-legal context of the Roman Empire?

Written by a select international group of leading privacy scholars, Social Dimensions of Privacy endorses and develops an innovative approach to privacy.

This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

The author researched the motivations of bureaucrats to integrate refugees into welfare services even when they do not have any legal obligation to do so.

Sanne Kellij and colleagues systematically reviewed 142 articles, examining evidence for three hypotheses on the relation between victimization and social information processing.

Robotics, using social mechanisms like hormonal modulation, may accelerate our understanding of core sociality principles. By looking at social robotics through an evolutionary lens, we propose this field as a promising framework to investigate the fundamental bricks of sociality from an evolutionary…

The availability of indicators based on social media has opened the possibility to track the online interactions between social media users and scholarly entities.

The master's specialisation Data Science: Computer Science at Leiden University provides students thorough knowledge and understanding of statistical and computational aspects of data analysis, including their application in databases, advances in data mining, networks, pattern recognition, and deep…

A mosaic is the only image which can do justice to museums in the Caribbean. They are as diverse and plentiful as the many communities which form the cores of their organizations and the hearts of their missions. These profoundly social museums adopt participatory practices and embark on community engagement…

Nematic liquid crystals form the key ingredients of most tv screens. The active version of these complex fluids forms a useful model for physicists to research the responses of active matter—like bacteria or traffic flows—to mechanical and geometrical cues. An international research team publishes their…

The key question addressed in this family study is whether the psychophysiological and neurocognitive abnormalities often reported in SAD patients are heritable and can thus be found in family members of SAD patients as well. Determination of heritability of these deficiencies is essential for endophenotyping.…

After your graduation, Leiden University would love to stay in touch with you. Alumni are an important part of the university; with your experience we can improve the education, and you can be part of a valuable network full of knowledge and experience. Find out what options you have to stay in touch…

What is and should be the role of universities in supporting business? How can business benefit more of relationships with science? And what is the role of policy makers in supporting a productive relationship between science and business? Professor Simcha Jong Kon Chin examines the interactions between…

Because thin systems can deform along the thickness with relative ease, the interplay between surface mechanics and geometry plays a fundamental role in sculpting their three-dimensional shape.

This article by Honorata Mazepus and Florian van Leeuwen in the journal Governance: An International Journal of Policy, Administration and Institutions looks at how evaluations of authorities were influenced by four aspects of a governmental response to a hypothetical disaster.

Novin, Bos, Stevenson and Rieffe investigated factors that may explain why some adolescents react more angrily than others in this type of situation. In their realistically designed gaming environment, the (pre-programmed) fellow player suddenly started…

In a longitudinal study, Eichengreen and colleagues explored how the certain aspects of emotional intelligence impact the development of adolescents’ mental health, thus identifying potential warning signs and targets for intervention programs. Despite a higher risk for mental health issues and lesser…
