Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

Growing public backlash against international organizations (IOs) and attacks of national political elites on the rule of law increasingly challenge governance by IOs.

Recently, studies have shown the similarities and differences in sources of meaning between religionists, ‘nones’ and atheists (see several studies of Schnell and others). The present study that will be conducted in three European countries tries to clarify the relationship between meaning giving and…

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

The Future of Multilateralism addresses current challenges and future perspectives of international and regional organizations. It aims to uncover how stable the foundations of global cooperation really are, particularly in the light of the latest unilateral and protectionist practices of international…

Regenerative medicine is a new way of treatment that helps impaired cells, tissues, and organs work well again. We do this by repairing, replacing, or restoring cells, tissues, and organs after damage from illness or injury. This includes treating long-term diseases such as diabetes, kidney diseases,…

This article explores how employees use leadership behaviours and how characteristics of the organizational context affect their engagement in leadership.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

Petra van der Bekerom, Joris van der Voet, and Johan Christensen, three assistant professors at Leiden University, conducted a large-scale survey experiment about whether citizens are more negative about failing service delivery than private organizations.

This article aims to explore the determinants of inclusive leadership. This type of leadership is valued for social equity and fairness.

The central theme of the NWO-project ‘The Promise of Organization’ is the evolution of political organization during the 19th century. We focus on the enthusiasm, arguments and concrete activities of the organizers as well as the criticism offered by opponents of modern political organization.

Netherton Syndrome (NTS) is a rare genetic skin disease caused by mutations in the serine protease inhibitor Kazal-type 5 gene, which encodes the lympho-epithelial Kazal-type-related inhibitor. NTS patients have a profound impaired skin barrier function. Because SC lipids play a crucial role in the…

This paper describes two synthetic lipid models designed to replace human stratum corneum (SC) in studies of the impact of volatile organic chemicals on the molecular organization of the skin barrier lipids.

It is the aim of this project to better understand how the physical properties of lipids influences the structure and overall barrier function of the skin.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

Beyond Empires explores the complexity of empire building from the point of view of self-organized networks, rather than from the point of view of the central state.

This study discusses the position of the monasteries in pre-1950s Tibetan societies and how that position was informed by Buddhist monastic ideology.

Physicians and researchers of the Leiden University Medical Center (LUMC) and Leiden University are working on therapies for restoring damaged organs such as hearts and kidneys. They are even trying to construct tailor-made organs. Read more on this topic in the new science dossier on Vascular and Regenerative…

Public management scholars have long debated public and private sector differences. However, the generalizability of empirical results has been limited due to the shortage of cross-national studies.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Drug induced organ toxicity is the main problem of the drug development and drug usage in the clinic. The liver and kidneys are the most sensitive organs towards drug induced toxicity.

Performances of solo keyboard repertoire can sound more or less polyphonic depending on the performer’s use of divergence in expression.

In January 2014, the research project The Promise of Organization hosted a fruitful three-day conference:

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

Can we develop new enzymes and cell factories to upgrade current enzyme cocktails towards complete degradation of biomass?

This research focuses on figurative Byzantine mosaic-floors that have been excavated in the geographical area of the ancient provinces of Palestina and Arabia (current Israel, PA and Jordan) dating to the Late 5th, 6th and early 7th centuries C.E.

The project re-examines the role of the Catholic, Protestant and Orthodox missionaries in the cultural and social developments of the Middle East and their interactions with the indigenous communities, from the nineteenth century until today. It seeks to discover and retrace such ‘entangled histories’…

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…
