Barriers to technology transfer and their elimination

An analogy between the flow of technology and the flow of electricity is used as a method to analyze technology transfer. This effort is expanded by an analogy to the Lewin's field theory in Social Science. An effort is then made to understand better the types of barriers to technology transfer. Several classes of barriers are identified and are then discussed in detail.     

Should the EU Protect Democracy and the Rule of Law inside Member States?

Against the background of recent developments in Hungary, the article discusses the question whether the European Union ought to play a role in protecting liberal democracy in Member States. First, it is argued that the EU has the authority to do so, both in a broad normative sense and in a narrower legal sense (though the latter is more likely to be disputed). The article then asks whether the EU has the capacity to establish a supranational militant democracy; here it is argued that at the moment both appropriate legal instruments and plausible political strategies are missing. To remedy this situation, the article proposes a new democracy watchdog, analogous to, but more powerful than, the Venice Commission. Finally, it is asked whether EU interventions would provoke a nationalist backlash. There is insufficient evidence to decide this question, but the danger of such a backlash probably tend to be overestimated.     

Identification of some factors influencing soil transfer on shoes

In criminal activities, soil can be transferred from a crime scene to items linked with a perpetrator; for example, shoes, cars or tools. Several parameters will influence the quantity of soil transferred in a given scenario. The knowledge of the most influential factors can help the expert to assess the evidence using a logical approach at the activity level or to predict the amount of soil that can be expected in a given scenario. The influence of five chosen parameters, namely the shoe profile, shoe size, walker's weight, soil type and soil humidity were assessed using Design of Experiment (DOE) in order to understand their influence on soil quantity transferred on shoes.The Faced Central Composite Design (FCCD) using a quadratic model was found to be highly significant, thus they could be adequately used to model and to interpret the amount of soil recovered from one shoe.These designs demonstrate that the characteristics of the donor (soil type and soil humidity), as well as a combination of these two factors have a very significant impact on the soil transfer. The characteristics of the receptor (shoe profile, shoe size and walker's weight) also have an impact on the transfer but to a lesser extent.Globally, this research provides valuable information for the forensic scientist both in investigative mode: evaluation of the soil quantity possibly transferred on shoes, and in the evaluative steps: is the quantity of soil found on the suspect shoes in accordance to the proposition/scenario given by the prosecution and the defence?
