TY - JOUR A1 - Fuchs, Christoph A1 - Beck, Daniel A1 - Lienland, Bernhard A1 - Kellner, Florian T1 - The role of IT in automotive supplier supply chains JF - Journal of Enterprise Information Management N2 - Purpose The purpose of this paper is to explore the impact of information technology (IT) on supply chain performance in the automotive industry. Prior studies that analyzed the impact of IT on supply chain performance report results representing the situation of the “average industry.” This research focuses on the automotive industry because of its major importance in many national economies and due to the fact that automotive supply chains do not represent the supply chain of the average industry. Design/methodology/approach A research model is proposed to examine the relationships between IT capabilities, supply chain capabilities, and supplier performance. The model divides IT capabilities into functional and data capabilities, and supply chain capabilities into internal process excellence and information sharing. Data have been collected from 343 automotive first-tier suppliers. Structural equation modeling with partial least squares is used to analyze the data. Findings The results suggest that functional capabilities have the greatest impact on internal process excellence, which in turn enhances supplier performance. However, frequent and adequate information sharing also contributes significantly to supplier performance. Data capabilities enable supply chain capabilities through their positive impact on functional capabilities. Practical implications The findings will help managers to understand the effect of IT implementation on company performance and to decide whether to invest in the expansion of IT capacities. Originality/value This research reports the impact of IT on supply chain performance in one of the most important industries in many industrialized countries, and it provides a new perspective on evaluating the contribution of IT on firm performance.

Die Daten sind häufig unvollständig, unsicher und ungenau. Ein Beispiel hierfür ist das OpenStreetMap Projekt, bei dem Nutzer auf der ganzen Welt einmal mehr und einmal weniger „sauber“ bzw. vollständig Daten beisteuern. In diesem Beitrag wird gezeigt, ob sich diese Daten eignen um ein betriebswirtschaftliches Problem zu lösen. Ein konkretes Fallbeispiel verdeutlicht, wie gut Standortentscheidungen einer Fast Food Kette unter Anwendung fortgeschrittener datenanalytischer Verfahren, wie bspw. Künstlicher Neuronaler Netze, Entscheidungsbäume und Logit-Modelle, nachempfunden werden können. Als Grundlage dienen die Daten des OpenStreetMap Projekts. Im Konkreten geht es darum, potenzielle Filialstandorte hinsichtlich deren Güte mittels OpenStreetMap Daten zu klassifizieren und die prognostizierten Lokationen mit tatsächlichen Standortentscheidungen zu vergleichen. Dabei zeigt sich, dass die Daten des OpenStreetMap Projekts grundsätzlich für die Prognose von Standorten geeignet sind. Allerdings ist die Wahl des datenanalytischen Verfahrens von Bedeutung. Im vorliegenden Fall konnte mit Hilfe der Künstlichen Neuronalen Netze das beste Prognoseergebnis erzielt werden.

The Austrian W-INN pilot study, carried out between 2010 and 2012, used a cross-sectional mixed-methods design (video-based observation and questionnaires) to research possible pedagogical differences and similarities between male and female educators, and their impact on boys’ and girls’ behaviour in early childhood education institutions. Ten Austrian Early Childhood Education and Care (ECEC) groups were recruited: 5 female-only and 5 mixed-gender teams of educators, 30 children (15 boys, 15 girls) aged 4–6. Analysis of data on educational dimensions reveal male and female educators hardly differ (the exception, men are significantly more permissive). Mixed-gender teams produce significantly greater social mobility among children than do female-only teams. Analysing children’s behaviour towards educators, clear gender specific effects can be found across various levels of inquiry: girls react less obviously to an educator’s gender; boys, especially, are drawn significantly more frequently to a man in the ECEC team. Implications for pedagogical professionalism as well as limitations of the results are discussed.

The components of the transfer system are characterized by simulation and experiments in terms of associated scattering parameters. Characterizing the efficiency of the coupled resonators, RF signal power transmission is examined for high power transfer as well as for low power DC supply utilizing a voltage doubler rectifier. With an enhanced butterfly structure coupler, unmodulated RF power transmission of 17.3 W is achieved with an efficiency of more than 95%. Furthermore, signal transmission of Pulse-Width-Modulated (PWM) signals with frequencies up to 5 MHz is demonstrated.

Here, we investigated the development of these two opposing effects of such part-list cuing in children. Using listwise directed forgetting to manipulate study context access, three child age groups (7–8, 9–11, and 13–14 years) and young adults studied a list of items and, after study, were asked to either forget or continue remembering the list. After presentation of a second list, participants were tested on predefined target items from the original list in either the presence or absence of the list’s remaining (nontarget) items serving as retrieval cues. Results revealed that part-list cuing impaired recall of to-be-remembered target items regardless of age. In contrast, part-list cuing improved recall of to-be-forgotten target items in the adult and the oldest child groups but not in the two younger child groups. This finding suggests a developmental dissociation between the two opposing effects of part-list cuing, indicating that the beneficial effect develops later than the detrimental effect. In particular, following the view that the beneficial effect of part-list cuing arises from reactivation of the study context, the results suggest that elementary school children have difficulty in capitalizing on context reactivation.

The present study investigated this forward testing effect in spatial memory. In two experiments, participants studied four successively presented 3 × 3 arrays, each composed of the same nine objects. They were asked to memorize the locations of the objects which differed across the four arrays. Following presentation of Arrays 1–3, memory for the object locations of the respective array was tested (testing condition), or the array was re-presented for additional study (restudy condition). Thereafter, Array 4 was presented and tested in both the testing and the restudy condition. In Experiment 1, testing was self-paced, whereas in Experiment 2, testing time was controlled by the experimenter. Consistent across the two experiments, testing was found to enhance location memory for Array 4, relative to restudying. Furthermore, testing also reduced the number of confusion errors (i.e., the tendency to misplace objects to locations on which they had appeared previously) made during recall of Array 4, suggesting that testing reduced the interference potential of prior information. The results indicate that testing can enhance subsequent learning of spatial information by reducing the build-up of proactive interference from previously studied information.

However, current healthcare has several shortcomings regarding mobility sustainment of older adults, namely a narrow focus on the underlying pathology, fragmentation of care across services and health professions and deficiencies in personalising care based on patients’ needs and experiences. A tailored healthcare strategy targeted at mobility of older adults is still missing. Objective The objective is to develop multiprofessional care pathways targeted at mobility sustainment and social participation in patients with vertigo/dizziness/balance disorders (VDB) and osteoarthritis (OA) . Methods Data regarding quality of life, mobility limitation, pain, stiffness and physical function is collected in a longitudinal observational study between 2017 and 2019. General practitioners (GPs) recruit their patients with VDB or OA. Patients who visited their GP in the last quarter will be identified in the practice software based on VDB and OA-related International Classification of Diseases 10th Revision. Study material will be sent from the practice to patients by mail. Six months and 12 months after baseline, all patients will receive a mail directly from the study team containing the follow-up questionnaire. GPs fill out questionnaires regarding patient diagnostics, therapy and referrals. Ethics and dissemination The study was approved by the ethical committee of the Ludwig-Maximilians-Universität München and of the Technische Universität Dresden. Results will be published in scientific, peer-reviewed journals and at national and international conferences. Results will be disseminated via newsletters, the project website and a regional conference for representatives of local and national authorities.

With the use of liquid pistons and one of the most efficient thermodynamic cycles known, the Stirling cycle, this product has the potential to outperform rival solar cooling technologies while providing inexpensive, reliable, quiet, environmentally-friendly, and efficient solar cooling for residential use, due to its straightforward manufacturing, simple design and inert working gas. Presented in this paper are the newest results of the theoretical and experimental investigation into deducing the key design parameters and system configuration of the so-called Liquid Piston Stirling Cooler (LPSC), which will help lead to optimal performance. Computer models of the complex unconstrained system have been constructed and validated using the modelling software Sage and shown to replicate system behavior with reasonable accuracy in experiments. The models have been used to predict system improvements and identify limitations imposed by the use of liquid pistons. The results to date provide a unique insight into a relatively little studied area in Stirling cycle research.

Purpose This study aims to bridge the gap between the ICF and occupational therapy specific concepts, represented by occupational therapy models and their derived assessments. Method Occupational therapy assessments in relation to their models were systematically linked to the ICF, and a compatibility analysis was conducted. To strengthen reliability of the linkings, feedback from the respective assessment hosts was obtained. Findings Linking tables were developed for the Assessment of Motor and Process Skills, the Canadian Occupational Performance Measure, and the Model of Human Occupation Screening Tool. Similarities and differences between the ICF and the three assessments and their associated models show how they differ from and complement each other. Implications The findings of this study lay the foundation for standardized documentation in occupational therapy and enhance the practicability of the ICF.
