Auf der Grundlage vorhandener Sturmflut-Messdaten aus dem Bereich der Uferlinie vor Westerland werden Gegebenheiten der Sturmbrandung am Modell resonanter Beckenschwingungen bezüglich der Ausprägung von Reflexion, Resonanz und anomaler Dispersion untersucht. Das Auftreten partiell stehender Wellen bedeutenden Ausmaßes unterstützt die These des Autors von der „Sturmwellenresonanz“. Durchschnittliche Abbruchraten von der Randdüne Westerland werden für extreme Sturmflutwasserstände zu 1,5m/h abgeschätzt. Based on existing storm surge data from the inshore and foreshore zone of Sylt island/North Sea, the circumstances of storm surf are analyzed with respect to the model of resonant basin oscillations, marked by reflection, resonance and anomalous dispersion. Partial standing waves of impressive extent support the author's finding of a „storm wave resonance“. Average sand removal rates can be estimated as 1.5m/h at heavy storm surge action.

The design of support structures of offshore wind turbines contains high number of design variables that influence load characteristics and structural responses. These variables are stochastic and cause many uncertainties. Some of them are examined in this study. It is investigated how scattering of site conditions and load parameters affect the structural response. It is exemplified in terms of stresses that contribute to the accumulated fatigue damage within a monopile substructure. Random sampling of combinations of site conditions and load parameters is performed in order to classify the effects of parameter scattering on the stress variability by means of Sobol’ indices. Analysis shows that the highest influence on stress outputs have the variations in the load parameters. The reason is the sensitivity of the structural dynamical response to the wave height increase and decrease of distance between the wave peak frequency and the structural eigenfrequencies. © 2017 ISOPE

With the co-operation of a further 13 institutes and as a continuation of our own epidemiological-statistical survey, we recorded the total and relative distribution (frequency profile) of the blood alcohol concentration of car drivers for the 3rd quarter 1990 and the 1st quarter 1991. The participating institutes recorded almost 27,000 blood samples and compared them with results of the first part of the study (1989). The survey dealt separately with sex-, age- and time of day-distribution of drivers involved and not involved in road accidents. One of our repeatedly presented field research into the problem of "alcohol and road safety", once again, provided to be a useful method in the run-up to the unprejudiced alcohol test which we are striving for. We noticed characteristic changes in the frequency profiles of the old and the new counties (Bundesländer) in Germany in the 1st (1989) and the 2nd (1990/91) report of the study. The results of Police supervisory operations in the administrative district of Cologne have basically given useful indications as to their epidemiological-statistical value as evidence.

Mortality from ischemic heart disease (ICD 410-414) is changing. Remarkable decreases have been observed in the age groups from 35-64 years, while overall mortality (all age groups) has remained approximately stable. In Switzerland this has meant a gain of some 4700 life years in the period 1988 to 1993 in the working population (35-64 years). The object of this study was to assess the associated change in indirect costs (productivity losses) due to premature death, using the human capital approach. The indirect costs were CHF 519 million (CHF 7.5 million per 100,000 population) in 1993. This represents approximately half of all indirect costs (and 25% of the total costs generated by the disease). Compared with the year 1988, a decrease in productivity losses due to premature death was observed amounting to CHF 46 million (-11%) in constant Swiss francs. Society benefits from this decrease in indirect costs, a desirable development hardly ever mentioned.

The aim of this paper is to test empirically the effect of human capital investment on economic development by using time series methods for the period 1981–2006 in Turkey. We employ the real per capita growth rate as a depented variable and physical capital and human capital as indepented variables. Growth rate of total fixed capital is used for total physical capital variables. In case of human capital; the share of total education expenditure in GDP, the share of total health expenditure in GDP and rate of school enrollment are used by turns. The main hypothesis is to test whether the primal factor is human capital in Turkish economic development. To test this hypothesis we use Romer’s (1990) Endogenous Technological Change Model (ETCM). The Engle-Granger two step co-integration method is used with time series.The econometric results indicate that physical and human capital accumulation affects positively Turkish economic development. But, when we apply model selection criterion, the main result of this paper show that the Turkish economy has acchieved endogenous growth depending on physical capital rather than human capital.

Dies ist das dritte Webinar in der „CLARITY für die Klimaresilienz“ (Clarity4CR) Webinarreihe und das erste in deutscher Sprache. Es präsentiert die CLARITY-Methodik zur Klimawandel-Risikobewertung, Impakt-Analyse, und Anpassungsplanung, stellt den "Advanced Urban Screening" Service vor und erläutert die Ergebnisse der CLARITY-Expertenstudie in Linz. This webinar is part of the CLARITY4ClimateResilience series. Other webinars from this series are available at https://www.gotostage.com/channel/climate-adaptation
