  The implementation of computerized critical care information systems (CCIS) can improve the quality of clinical care and staff satisfaction, but also holds risks of disrupting the workflow with consecutive negative impacts. The usability of CCIS is one of the key factors determining their benefits and weaknesses. However, no tailored instrument exists to measure the usability of such systems. Therefore, the aim of this study was to design and validate a questionnaire that measures the usability of CCIS. Following a mixed-method design approach, we developed a questionnaire comprising two evaluation models to assess the usability of CCIS: (1) the task-specific model rates the usability individually for several tasks which CCIS could support and which we derived by analyzing work processes in the ICU; (2) the characteristic-specific model rates the different aspects of the usability, as defined by the international standard “ergonomics of human-system interaction”. We tested validity and reliability of the digital version of the questionnaire in a sample population. In the sample population of 535 participants both usability evaluation models showed a strong correlation with the overall rating of the system (multiple correlation coefficients ≥0.80) as well as a very high internal consistency (Cronbach’s alpha ≥0.93). The novel questionnaire is a valid and reliable instrument to measure the usability of CCIS and can be used to study the influence of the usability on their implementation benefits and weaknesses.

• Profiling maritime communication by non-native speakers: A quantitative comparison between the baseline and standard marine communication phraseology

  This paper compares ESP communication by non-native speakers of Maritime English with communication outside a nautical setting in order to profile its structural idiosyncrasy. Vocabulary growth, word frequencies, lexical and key word densities, and grammar diversity as dependent linguistic variables observed in transcribed full-mission simulation exercises are contrasted to the Brown Corpus, the Vienna-Oxford International Corpus of English and the Standard Marine Communication Phrases (SMCP). Using quantitative linguistics, inherent structural patterns of nautical team communication are identified and similarities and variations highlighted. Significant differences found in all linguistic features are gauged by means of the Probability of Superiority (PS) effect size. A linguistic profile is created which quantifies the observed language patterns and provides a quantitative model for the linguistic genre of this particular discourse community. The model fills the gap of quantitative research on empirical bridge team communication samples and delivers a valid tool for estimating the magnitude of observed linguistic effects.

• A hybrid approach to configure eco-efficient supply chains under consideration of performance and risk aspects

  Brandenburg, M. (2017). A hybrid approach to configure eco-efficient supply chains under consideration of performance and risk aspects. Omega, 70, 58–76. http://doi.org/10.1016/j.omega.2016.09.002

  Abstract

  Formal models that support multi-criteria decision making represent a strongly growing area in sustainable supply chain management research. However, uncertainties and risks are seldom considered in quantitative models for green supply chain (SC) design. The paper at hand suggests a hybrid approach to configure an eco-efficient SC for a new product under consideration of economic and environmental risks. Discrete-event simulation is applied to assess the financial, operational and environmental performance of different SC configuration options while the value-at-risk concept is adapted to evaluate related SC risks. The analytic hierarchy process is employed to solve the resulting multi-criteria decision problem of choosing the best option. The approach is illustrated at a case example of a fast moving consumer goods manufacturer.

• Underlying Processes of an Inverted Personalization Effect in Multimedia Learning – An Eye-Tracking Study

  Zander, S., Wetzel, S., Kühl, T., & Bertel, S. (2017). Underlying Processes of an Inverted Personalization Effect in Multimedia Learning – An Eye-Tracking Study. Frontiers in Psychology, 8, 2202. http://doi.org/10.3389/fpsyg.2017.02202

  Abstract

  anzeigen ▸

  One of the frequently examined design principles in multimedia learning is the personalization principle. Based on empirical evidence this principle states that using personalized messages in multimedia learning is more beneficial than using formal language (e.g., using ‘you’ instead of ‘the’). Although there is evidence that these slight changes in regard to the language style affect learning, motivation and the perceived cognitive load, it remains unclear, (1) whether the positive effects of personalized language can be transferred to all kinds of content of learning materials (e.g., specific potentially aversive health issues) and (2) which are the underlying processes (e.g., attention allocation) of the personalization effect. German university students (N = 37) learned symptoms and causes of cerebral hemorrhages either with a formal or a personalized version of the learning material. Analysis revealed comparable results to the few existing previous studies, indicating an inverted personalization effect for potentially aversive learning material. This effect was specifically revealed in regard to decreased average fixation duration and the number of fixations exclusively on the images in the personalized compared to the formal version. These results can be seen as indicators for an inverted effect of personalization on the level of visual attention.
