This paper presents a model of recurrent multinomial sequences. Though there exists a quite considerable literature on modeling autocorrelation in numerical data and sequences of categorical outcomes, there is currently no systematic method of modeling patterns of recurrence in categorical sequences. This paper develops a means of discovering recurrent patterns by employing a more restrictive Markov assumption. The resulting model, which I call the recurrent multinomial model, provides a parsimonious representation of recurrent sequences, enabling the investigation of recurrences on longer time scales than existing models. The utility of recurrent multinomial models is demonstrated by applying them to the case of conversational turn-taking in meetings of the Federal Open Market Committee (FOMC). Analyses are effectively able to discover norms around turn-reclaiming, participation, and suppression and to evaluate how these norms vary throughout the course of the meeting.

The primary objective of this thesis was to shed light on the marine aquaculture sector in each of the two countries and to sort out chances and risks for future mariculture development in the two regions. The innovative idea of this research was to analyze the attitudes towards marine aquaculture from a public, i.e. social and political point of view. This thesis yields data and results from quantitative and qualitative surveys carried out during the project in both Israel and Germany. The information provided here is suitable to guide and support policy-making in the marine aquaculture sector in each of the two countries and beyond.

Blood tends to coagulate during therapies with extracorporeal circulation like dialysis or surgery with the use of heart-lung-machines. To study the effects of the incipient coagulation and to develop new and continuous supervising methods for blood therapies, a fluid mimicking rheological and acoustical blood properties with nearly the same amount of particles as blood is necessary. We enhanced the International Electrotechnical Commission Doppler blood mimicking fluid recipe to be used at physiological hematocrit values and to mimic incipient plasma coagulation and blood clotting. This paper presents the recipe, acoustical and rheological data of the refined blood mimicking fluid. ; Tina A.
