Shape But Not Color Facilitates Two-Year-Olds’ Search Performance in a Spatial Rotation Task
(2018)
Children younger than 3 years of age often fail to track hidden objects that are rotated together with identical hiding containers, which might be due to relatively complex paradigms. We examined whether 2-year-olds (N = 28) are already able to track spatial rotations (i.e., by 90° and 180°) if the task is facilitated by increasing the visual discriminability of the hiding containers by means of different shapes and different colors. Children performed above chance level in all conditions except for the condition in ...

Let’s twist again! Embodiment effects in spatial judgments on human figures rotated along a vertical axis
(2017)
We investigated whether individuals used mental rotation and embodiment for arm laterality judgments of human figures that were stepwise rotated from back view to front view along a vertical axis. In Experiment 1, figures’ heads were always shown in profile, while only the bodies were rotated. Judgments were faster and more correct when figures were presented in back view compared to front view, but the relation between reaction times (RTs) and rotation angles was not strictly linear. In addition, judgments on figures ...

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds
(2015)
Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence ...

Das New Public Management als Grundlage für eine effiziente und effektive Verwaltung, untersucht am Beispiel der Verwaltung von Hoima, Uganda
(kassel university press, 2010-08-09)
In der Dissertation wird die Möglichkeit untersucht, die deutschen Erfahrungen mit dem New Public Management (NPM) für die Entwicklung der Verwaltung in Uganda nutzbar zu machen. Inhaltlich betrifft die Arbeit 3 Hauptkomponenten: Das NPM als Konzept für die öffentliche Verwaltung, die Erfahrungen mit dem NPM in Deutschland, die Transfermöglichkeit des NPM und insbesondere der deutschen Erfahrungen mit dem NPM nach Uganda, wobei auch die deutschen Erfahrungen mit der Verwaltungshilfe nach dem 1990 erfolgten Beitritt ...

Modellierung und Simulation viskoelastischer Polymerschmelzen
(kassel university press, 2012)
Die vorliegende Dissertation behandelt Kunststoffschmelzen als viskoelastische Fluide, bzw. im allgemeinen als Nicht-Newtonsche Fluide. Schmelzen dieser Art zeigen in der Tat viskoelastisches Verhalten, aber auch u.a. Strukturviskosität bzw. Scherentzähung und
Normalspannungsdifferenzen.
Diese Fülle an verschiedenen, beobachtbaren Phänomene werden mit linearen Ansätzen nicht mehr ausreichend beschrieben. In dieser Arbeit werden Modelle eingesetzt, die auf makroskopischen und mikroskopischen Konzepten basieren. Dazu ...

Cyclic degradation of Co49Ni21Ga30 high-temperature shape memory alloy - On the roles of dislocation activity and chemical order
(2015)
Conventional shape memory alloys (SMAs), such as binary Ni-Ti, are typically limited to service temperatures below 100 °C. Recent studies on Co-Ni-Ga high temperature (HT) SMAs revealed the potential that these alloys can be used up to temperatures of about 400 °C. Analysis of the cyclic functional properties showed that degradation in these alloys is mainly triggered by intensive dislocation motion. However, data on the cyclic stress-strain response and the mechanisms leading to functional degradation of Co-Ni-Ga ...

The Sundarbans in Bangladesh
(2019)
Bangladesh is an agricultural-based country. Agriculture contributes 42.70% (BER) in the labor market through 4 categories namely crops, fisheries, livestock, and forestry. Forestry has the most significant role in renovation of infrastructures and balancing the natural environment. Due to human and natural induced threats, the forest resources are in danger and currently, the percentage of forest in Bangladesh is 13.22 % (BER). The sector is still mistreated on the basis of compared to the other three parts of ...

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...
