Confirmatory Factor

The present study explores the factorial structure and the degree of measurement invariance of 12 divergent thinking tests. In a large sample of German students (N = 1328), a three-factor model representing verbal, figural, and numerical divergent thinking was supported. Multigroup confirmatory factor analyses revealed that partial strong measurement invariance was tenable across gender and age groups as well as school forms. Latent mean comparisons resulted in significantly higher divergent thinking skills for females and students in schools with higher mean IQ. Older students exhibited higher latent means on the verbal and figural factor, but not on the numerical factor. These results suggest that a domain-specific model of divergent thinking may be assumed, although further research is needed to elucidate the sources that negatively affect measurement invariance.

Architectural Knowledge

One of the key obstacles to pervasive deployment of FPGA accelerators in data centers is their cumbersome programming model. Open source tooling is suggested as a way to develop alternative EDA tools to remedy this issue. Open source FPGA CAD tools have traditionally targeted academic hypothetical architectures, making them impractical for commercial devices. Recently, there have been efforts to develop open source back-end tools targeting commercial devices. These tools claim to follow an alternate data-driven approach that allows them to be more adaptable to the domain requirements such as faster compile time. In this paper, we present RWRoute, the first open source timing-driven router for UltraScale+ devices. RWRoute is built on the RapidWright framework and includes the essential and pragmatic features found in commercial FPGA routers that are often missing from open source tools. Another valuable contribution of this work is an open-source lightweight timing model with high fidelity timing approximations. By leveraging a combination of architectural knowledge, repeating patterns, and extensive analysis of Vivado timing reports, we obtain a slightly pessimistic, lumped delay model within 2% average accuracy of Vivado for UltraScale+ devices. Compared to Vivado, RWRoute results in a 4.9× compile time improvement at the expense of 10% Quality of Results (QoR) loss for 665 synthetic and six real designs. A main benefit of our router is enabling fast partial routing at the back-end of a domain-specific flow. Our initial results indicate that more than 9× compile time improvement is achievable for partial routing. The results of this paper show how such a router can be beneficial for a low touch flow to reduce dependency on commercial tools.

Open source software (OSS) has gained considerable attention recently in healthcare. Yet, how and why OSS is being adopted within hospitals in particular remains a poorly understood issue. This research attempts to further this understanding. A mixed-method research approach was used to explore the extent of OSS adoption in hospitals as well as the factors facilitating and inhibiting adoption. The findings suggest a very limited adoption of OSS in hospitals. Hospitals tend to adopt general-purpose instead of domain-specific OSS. We found that software vendors are the critical factor facilitating the adoption of OSS in hospitals. Conversely, lack of in-house development as well as a perceived lack of security, quality, and accountability of OSS products were factors inhibiting adoption. An empirical model is presented to illustrate the factors facilitating and inhibiting the adoption of OSS in hospitals.

Lifecycle Management

Product lifecycle management (PLM) is a valuable concept for the implementation of advanced manufacturing method. Based on the principle of PLM, the involved manufacturing sessions were integrated, and scientifically managed in order to improve the cooperation and innovation ability of a modern enterprise. The knowledge resource allocation service is one of key technologies for the successfully implementation of product lifecycle management. Aim at the knowledge resource allocation service, an product lifecycle oriented domain specific model (p-DSM) was proposed in the paper, which will help to guide the knowledge resource modeling and resource allocation, and provide a system framework for knowledge based enterprise management system.

Despite the important role that teachers’ professional competencies play, domain-specific models of competence as well as established instruments to measure such competencies are lacking (e.g., Blömeke, Zlatkin-Troitschanskaia, Kuhn, & Fege, 2013 ). For this reason, a domain-specific model of competence and an instrument to measure prospective business and economics teachers’ professional competence in the domain of accounting was developed. This article focuses on the measurement of professional knowledge, which is a key facet of teachers’ professional competence. A corresponding test instrument is introduced and its measurement quality is reported. The test instrument used at 24 German universities (N = 1.158) comprises 49 items, distributed among different booklets following a multi-matrix design. All items have well functioning parameter values. In accordance with our hypothesis, a two-dimensional model fits the data best. The reliabilities of .64 (content knowledge) and .64 (pedagogical content knowledge) are satisfying. Thus, the developed instrument allows to gain a detailed understanding of prospective teachers’ professional knowledge in accounting.
