In this paper, we follow the fitness function classification of Nelson et al.

The robot controllers are evolved in simulation using NEAT and we investigate different tasks including obstacle avoidance and (periodic) goal homing. The best evolved controllers were then post-evaluated by examining their potential for adaptation, determining their convergence rates, and using cross-comparisons based on the different fitness function classes.

Service requesters state requirements on services. To satisfy these requirements, the new role of brokers, who are (human) actors building service compositions on the fly, is introduced. Brokers have to specify service compositions formally and comprehensively using a domain-specific language (DSL), and to use service matching for the discovery of the constituent services available in the market. The broker's choice of the DSL and matching approaches influences her success of building compositions as distinctive properties of different service markets play a significant role. In this paper, we propose a new approach of engineering a situation-specific DSL by customizing a comprehensive, modular DSL and its matching for given service market properties. This enables the broker to create market-specific composition specifications and to perform market-specific service matching. As a result, the broker builds service compositions satisfying the requester's requirements more accurately.

The present study describes dietary changes from childhood to adolescence, and their associations with parental education, family income, child education, body mass index (BMI), pubertal onset and screen-time sedentary behaviour. Methods Dietary data (n = 1232) were obtained from food frequency questionnaires at the 10- and 15-year follow-ups of the GINIplus birth cohort study. Intakes of 17 food groups, macronutrients and antioxidant vitamins, were described by a) paired Wilcoxon rank sum tests, comparing average intakes at each time-point, and b) Cohen’s kappa “tracking” coefficients, measuring stability of intakes (maintenance of relative tertile positions across time). Further, associations of changes (tertile position increase or decrease vs. tracking) with parental education, family income, child education, pubertal onset, BMI, and screen-time, were assessed by logistic regression and multinomial logistic regression models stratified by baseline intake tertile. Results Both sexes increased average intakes of water and decreased starchy vegetables, margarine and dairy. Females decreased meat and retinol intakes and increased vegetables, grains, oils and tea. Males decreased fruit and carbohydrates and increased average intakes of meat, caloric drinks, water, protein, fat, polyunsaturated fatty acids (PUFAs), vitamin C and alpha-tocopherol. Both sexes presented mainly “fair” tracking levels [κw = 0.21–0.40]. Females with high (vs. low) parental education were more likely to increase their nut intake [OR = 3.8; 95 % CI = (1.7;8.8)], and less likely to decrease vitamin C intakes [0.2 (0.1;0.5)], while males were less likely to increase egg consumption [0.2 (0.1;0.5)] and n3 PUFAs [0.2 (0.1;0.5)]. Females with a higher (vs. low) family income were more likely to maintain medium wholegrain intakes [0.2 (0.1;0.7) for decrease vs. tracking, and 0.1 (0.0;0.5) for increase vs. tracking], and were less likely to decrease vitamin C intakes [0.2 (0.1;0.6)]. Males with high education were less likely to increase sugar-sweetened foods [0.1 (0.1;0.4)]. Finally, BMI in females was negatively associated with decreasing protein intakes [0.7 (0.6;0.9)]. In males BMI was positively associated with increasing margarine [1.4 (1.1;1.6)] and vitamin C intakes [1.4 (1.1;1.6)], and negatively associated with increasing n3 PUFA. Conclusions Average dietary intakes changed significantly, despite fair tracking levels, suggesting the presence of trends in dietary behaviour during puberty. Family income and parental education predominantly influenced intake changes. Our results support the rationale for dietary interventions targeting children, and suggest that sex-specific subpopulations, e.g. low socio-economic status, should be considered for added impact.}}, author = {{Harris, Carla and Flexeder, Claudia and Thiering, Elisabeth and Buyken, Anette and Berdel, Dietrich and Koletzko, Sibylle and Bauer, Carl-Peter and Brüske, Irene and Koletzko, Berthold and Standl, Marie}}, journal = {{BMC Public Health}}, keywords = {{Puberty, Dietary intake, Dietary changes, Tracking, Determinants, Epidemiology}}, pages = {{841}}, title = {{{Changes in dietary intake during puberty and their determinants: results from the GINIplus birth cohort study}}}, volume = {{15}}, year = {{2015}}, } @article{28033, author = {{Bloh, Thiemo and Bloh, Bea and van Ophuysen, Stefanie}}, journal = {{Empirische Pädagogik}}, number = {{4}}, pages = {{505--520}}, title = {{{Lernpotential durch Lehrerkooperation.

To this end, the partial results of a verification run are used to construct a residual program (and residual assertions to be checked on it).

Hierfür existieren allerdings noch keine fertigen "Out of the box"-Lösungen, sodass hohe Investitionskosten für die Konzeption und Inbetriebnahme kundenspezifischer Lösungen entstehen. Kosten die kleine und mittlere Unternehmen (KMU) häufig nicht aufbringen können, wodurch ihnen die Umsetzung von Industrie 4.0 wesentlich erschwert wird. Vor diesem Hintergrund besteht ein erheblicher Bedarf an kostengünstigen Ansätzen für den Einstieg in Industrie 4.0. In diesem Beitrag wird ein Konzept zur Dezentralisierung bestehender Produktionssysteme auf Basis kostengünstiger Einplatinenrechner (engl.: Single Board Computer) am Beispiel des Raspberry Pi vorgestellt. Dabei wird jede Komponente eines bestehenden Produktionssystems mit einem Einplatinenrechner bestückt, der anschließend die Anbindung der Komponente an das Produktionsnetzwerk, dessen Rolle sowie die dafür notwendige Datenverarbeitung regelt. Zudem übernimmt der Einplatinenrechner die Kommunikation der Komponente innerhalb des gesamten Netzwerks. Das Konzept umfasst eine Kommunikationsarchitektur für ein Produktionsnetzwerk sowie die darauf aufbauende dezentrale Materialflusssteuerung.

Dies birgt große Unsicherheit bzgl. konkreter Entscheidungsprobleme (z.B. Produktstrategie: Wie soll der Wettbewerbsvorsprung über die Produktlebensdauer erhalten bleiben?). Wie diese Stakeholder auf strategische Entscheidungen reagieren, lässt sich allerdings nicht ohne weiteres vorhersagen (z.B. Preiskampf, Innovations-Offensive). Das Fortschreiben bisherigen Verhaltens kann zu Fehleinschätzungen führen. Somit ist es notwendig das Verhalten der relevanten Stakeholder systematisch vorauszudenken.

Dabei zeigen wir, wie Stakeholder identifiziert werden, die den größten Einfluss auf den Erfolg der gewählten Entscheidung haben.

Obwohl sich beide Lernende sehr unterschiedlich als Sprechende des Deutschen konstruieren, fixieren sie sich darauf, wie sie meinen zu klingen und folglich wahrgenommen zu werden.
