Paradigm Petrification in the Information Age. An Anatomisation of Knowledge Creation and Deliberation in Innovation Systems in the Human Services

In human service organisations, evidence-based practice (EBP) implies that practice and decision-making should be guided by empirical evidence in a systematic way. Policy makers and researchers argue that practitioners in many fields do not apply state-of-the-art methods and that they should rely on evidence in a more systematic way. Among the suggested reasons for this state of affairs we note la

On Matching Markets

This thesis gives a contribution to matching theory. It examines three one-to-one matching models: the roommate problem, the partnership formation problem and the assignment game. In the former two, it is known that stable matchings may not exist. In the latter, stable outcomes do exist; we examine if they still do if we generalize the model. The thesis consists of three separate papers. In the f

Iran's Moderate Moment: The Leader Just Let It Go

Whatever the cause of a centrist takeover after two successive terms of hardliner dominance in Iran, one thing is for sure: the election of Hassan Rouhani as president in 2013 gave a new lease of life to the Islamic Republic, with the guarantee that its foundational structures will remain unchallenged for many years to come. Considerably narrowing the widening state-society gap, however, it has en

Tyr-716 in the platelet-derived growth factor beta-receptor kinase insert is involved in GRB2 binding and Ras activation

Ligand stimulation of the platelet-derived growth factor (PDGF) beta-receptor leads to activation of its intrinsic tyrosine kinase and autophosphorylation of the intracellular part of the receptor. The autophosphorylated tyrosine residues mediate interactions with downstream signal transduction molecules and thereby initiate different signalling pathways. A pathway leading to activation of the GTP

A circuit technique improving the image rejection of RF front-ends

This work presents a technique to reduce the phase errors of quadrature signals. The proposed concept is demonstrated on a 2.4-GHz single-sideband up-converter in a 0.35-/spl mu/m BiCMOS process. The quadrature LO signals are obtained on-chip by means of two coupled oscillators, achieving a figure-of-merit of 186 dB. The image-rejection ratio improves by 7 to 11dB across the 28% LO tuning range wi

Insights from a vendor managed inventory implementation in an industrial context

Researchers have asked for practical examples of collaborative supply chain initiatives like VMI and how they are designed. Especially cases in other industrial settings than retail are rare. One important question to answer is how well these initiatives are working in other settings and how they could be designed to improve supply chain efficiency. The objective of this paper is to give a descrip
