Wrongfully Convicted: How the Dutch Deal with the Revision of Their “Miscarriages of Justice”

During most of the twentieth century the very existence of judicial errors was considered an awkward subject in the Dutch legal system. This article considers the change of attitude in recent years. In previous years there was a remarkable self-confidence within the criminal justice system (and in most of the scholarly writings) in doing things the ‘right way.’ After a few warnings from (only partly legally trained) scholars, who became interested in the functioning of the system, and moreover, after a few clear and undeniable cases of judicial error, there was a volte-face in the general feeling amongst both the public and the profession. It is the opinion of the authors that this shift in opinion is historically important. This article therefore intends to draw a picture of the current state of affairs in The Netherlands.     

Dichroism measurements in forensic fibre examination: Part 3 — Dyed cotton and viscose fibres

A number of dyed cellulosic fibres were examined with plane polarized light on their dichroic behavior by microscopy and microspectrophotometry (MSP-PPL). Significant dichroic effects (mostly hypochromic effects and hypsochromic bands shifts) were reported. The effect is related to the chemical structure: some dye structures always possess dichroism (azo, stilbene, thiazole and oxazine), some dyes demonstrate sometimes dichroic effects (anthraquinoid, indigoid) while other structures never demonstrate dichroic effects (sulphur, diphenylmethanes, triarylmethanes, phthalocyanines). In some cases a different dichroic behavior was found for the same dyes applied on cotton and on viscose.     

Global technological collaboration network: network analysis of international co-inventions

Global innovation networks are emerging as a result of the international division of innovation processes through, among others, international technological collaborations. At the aggregate level, the creation of technological collaboration between countries can be considered as mutually beneficial (or detrimental) and their random distribution is unlikely. Consequently, the dynamics and evolution of the technological collaborations can be expected to fulfil the criteria of a complex network. To study the structure and evolution of the global technological collaboration network, we use patent-based data of international co-inventions and apply the network analysis. In addition, extending the gravity model of international technological collaboration by network measures, we show that a country’s position in the network has very strong impact on the intensity of collaboration with other countries.
