A1 - Knappitsch, Eithne T1 - Culture and Entrepreneurship: The Political, Social and Individual Influences on Opportunity Entrepreneurs N2 - The impact of culture on entrepreneurship is a widely accepted phenomenon. Cultural factors influence entrepreneurship via different mechanisms on the macro-, meso-, and micro-level of a country. Building on existing research, we draw a clear link between national cultural dimensions and entrepreneurship, using a new model that arranges different cultural dimensions in groups based on their particular function: political, social, or individual (PSI-model) and that distinguishes between values and practices where relevant. The PSI-model provides a coherent theoretical framework on which different cultural dimensions and their impact on entrepreneurship can be analysed, allowing for particular attention to be drawn to social practices and social values. This paper contributes to a better understanding of the relationship between culture and entrepreneurship, providing empirical evidence of how specific cultural dimensions influence entrepreneurship. The findings are of relevance from a policy perspective and can be used to generate practical recommendations for national institutions interested in promoting entrepreneurship and entrepreneurial activities. The findings are also transferable to other fields related to national cultural dimensions such as level of innovation, investment, budgeting etc. T3 - Working Papers in Industrial Engineering - 3 KW - Entrepreneurship KW - Cultural Dimensions KW - National Culture KW - PSI Model Y1 - 2020 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:due62-opus-23837 SN - 2627-8375 PB - Hochschule Düsseldorf CY - Düsseldorf ER - TY - JOUR A1 - Fomin, Alexey A1 - Petelin, Daniil A1 - Jahr, Andreas T1 - Synthesis and Analysis of a Novel Linkage Mechanism with the Helical Motion of the End-Effector JF - Robotics Y1 - 2020 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:due62-opus-27736 SN - 2218-6581 N1 - Supplementary Material ist verfügbar: https://www.mdpi.com/2218-6581/9/3/53/s1 (Zip mit mov-Datei) VL - 9 IS - 3 SP - 1 EP - 15 PB - MDPI ER - TY - JOUR A1 - Girod, Kai A1 - Lohmann, Heiko A1 - Schlüter, Stefan A1 - Kaluza, Stefan T1 - Methanol Synthesis with Steel-Mill Gases: Simulation and Practical Testing of Selected Gas Utilization Scenarios JF - Processes Y1 - 2020 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:hbz:due62-opus-26928 VL - 8 IS - 12 PB - MDPI ER - TY - BOOK A1 - Kiel, Jürgen T1 - Einführung in die elektrische Energie- und Antriebstechnik N2 - Die zunehmende Automatisierung und der sensible Umgang mit (elektrischer) Energie spielen in der gesellschaftlichen Diskussion eine zunehmende Rolle. Die technischen Hintergründe sind hierbei nicht nur für die jeweiligen Experten von Bedeutung, sondern sind auch selbstverständlich Grundlagenwissen im Maschinenbau, in der Verfahrenstechnik und in der Energietechnik. Für genau diese Zielgruppe ist dieses Buch konzipiert. Um eine möglichst große Bandbreite an Themen abzudecken, wurde in vielen Bereichen vereinfacht, verkürzt und verallgemeinert, um zumindest den Kern der jeweiligen Problematik verständlich zu machen. Daher wird auch als Voraussetzung lediglich das Verständnis des elektrischen Kreises mit ohm’schen, induktiven und kapazitiven Verbrauchern erwartet. Außerdem wurde der Spagat zwischen Grundlagen- und Praxiswissen gewagt.

This results in an increasing demand for mobility solutions while it is also worldwide aimed to reduce greenhouse gas emissions. This paper summarizes the results of a comparative study concerning the greenhouse gas emissions (based on carbon footprint) caused by alternative urban passenger transportation systems. The emissions for the vehicles and their infrastructure are analyszed over the entire life cycle from manufacturing up to their end of life. An existing cable car sytem in La Paz, Bolivia was analysed and evaluated in comparison to other modes of transportation such as small busses, large busses and a tram. According to the system definitions and the considered balance framework the study shows that beside the use of the systems the materials and the manufacturing as well as the infrastructure have a significant impact on the total emissions over the life cycle. To put focus on the „true and real“ impacts to the society it is preferable to consider the measurement results in total absolute emissions.
