In this paper we present the Semantic Enhancement for the Open Journal Systems, SE4OJS, to generate semantically annotated documents. With this tool, we created a knowl-edgebase for psychology, KOBPSY.We have identified struc-tural document elements such as authors, sections, and do-main knowledge about diseases, population, treatments and more. Our corpus of documents comes from PsychOpen. The datasets we are building for each article include i) the RDF description of article metadata, e.g. information on ti-tle, keywords, authors and editors; ii) structural information such as sections, section types, paragraphs, in-text citations; and also, iii) RDF for content and annotations. We are structuring the annotations by using the Annotation Ontol-ogy. Our approach makes it possible to build concept-based queries; we are delivering a exible, reusable and adaptable set of tools for metadata enrichment and semantic process-ing of scientific documents in psychology. © 2015 ACM.

Two studies demonstrate the usefulness of a newly developed, direct assessment method of subjective conceptualizations of development across adulthood. Results of Study 1 (N = 234, 18-83 years) suggest that older adults anticipate stronger decline in four domains of functioning (subjective well-being, social relationships, cognition, physical functioning) than younger and middle-aged adults. Study 2 (N = 166, 20-85 years) showed that older adults' conceptualizations show less differentiation across domains than those of younger and middle-aged adults'. Results of both studies confirm lifespan notions of multidirectionality (expectations of gains and losses) but also show age-related differences in multidimensionality of developmental conceptions (i.e., differences in expected trajectories between domains). Moreover, results provide evidence that favorable conceptions impact perceived controllability and actual subjective well-being. © 2012 Hogrefe Publishing. Source

Large-scale three-dimensional aerodynamic shape optimization based on the compressible Euler equations is considered. Shape calculus is used to derive an exact surface formulation of the gradients, enabling the computation of shape gradient information for each surface mesh node without having to calculate further mesh sensitivities. Special attention is paid to the applicability to large-scale three dimensional problems like the optimization of an Onera M6 wing or a complete blended-wing-body aircraft. The actual optimization is conducted in a one-shot fashion, in which the tangential Laplace operator is used as a Hessian approximation, thereby also preserving the regularity of the shape.

The paper examines whether effects of an adaptable information literacy instruction program are associated with (a) adherence to the recommendations of online learning contents derived from a test of prior knowledge and (b) subjective evaluations of the program. An adaptable blended learning training for German psychology students was evaluated in a study with a pretest-posttest design. N = 64 advanced students completed two tests of scholarly information literacy, an information literacy self-efficacy scale, and an evaluation questionnaire. Participants who worked on more online materials than recommended based on their pretest performance did not differ in their gain scores from participants who exactly followed the recommendations. However, both groups outperformed participants who omitted recommended materials. According to subjective evaluations, the latter participants constitute a “risk group” with low subjective acceptance of online teaching which might need additional support during online learning or alternative forms of instruction. © Springer International Publishing Switzerland 2015.

In three studies we constructed a standardized test of procedural knowledge about information searching tailored to the domain of computer science, the PIKE-CS (Procedural information literacy knowledge test for computer science students). A skill decomposition was used to identify nine sub skills which can be classified into two broader categories: Development of search strategies and Application of search strategies. Based on the ratings of experts (N=7), a scoring key was developed. In a pilot study the test was administered to a sample of computer science students (N=18). The scale reached an internal consistency (Cronbach's alpha) of α=.78. Finally, the items were administered to N=89 first-year computer science students. The mean difference between subjects with vs. without programming experience in a professional context-which can be interpreted as a proxy for search experience-is significant, pointing to the validity of the test. © Springer International Publishing Switzerland 2014.
