And Performance

The development and performance of Patricia, a suite of (choice) models that can be used to analyze and predict activity-travel patterns, is reported. This suite of models, which differs from similar sequential utility-maximizing models of activity-travel patterns in that it incorporates a larger number of choice facets and choice options, was sequentially estimated with activity-travel data collected in the region of South Rotterdam, the Netherlands. The results of the estimation are satisfactory at the level of aggregated origin-destination matrices and individual activity patterns.

The Impact

Abstract Introduction The global Coronavirus (COVID-19) pandemic is having a great impact on all areas of the everyday life, including travel behaviour. Various measures that focus on restricting social contacts have been implemented in order to reduce the spread of the virus. Understanding how daily activities and travel behaviour change during such global crisis and the reasons behind is crucial for developing suitable strategies for similar future events and analysing potential mid- and long-term impacts. Methods In order to provide empirical insights into changes in travel behaviour during the first Coronavirus-related lockdown in 2020 for Germany, an online survey with a relative representative sample for the German population was conducted a week after the start of the nationwide contact ban. The data was analysed performing descriptive and inferential statistical analyses. Results and Discussion The results suggest in general an increase in car use and decrease in public transport use as well as more negative perception of public transport as a transport alternative during the pandemic. Regarding activity-related travel patterns, the findings show firstly, that the majority of people go less frequent shopping; simultaneously, an increase in online shopping can be seen and characteristics of this group were analysed. Secondly, half of the adult population still left their home for leisure or to run errands; young adults were more active than all other age groups. Thirdly, the majority of the working population still went to work; one out of four people worked in home-office. Lastly, potential implications for travel behaviour and activity patterns as well as policy measures are discussed.

Domestic heating contributes to a significant amount of energy usage in the Netherlands. Due to scare energy resources, attention to develop new and efficient technologies is increasing. At ECN, a burner driven heat pump employing thermoacoustic technology is being developed for possible applications in households and offices. The desired temperature lift is from 10 °C to 80 °C. As a first step the heat pump is driven by a linear motor. Measurements and performance analysis of the heat pump are presented in this paper. The heat pump has a coefficient of performance which is the ratio of heat produced to the work input of 1.38 when operating between 10 °C to 80 °C. The performance relative to maximum possible Carnot value is 26.5%.

The quality and performance of lecturers apart from the quality of their education, are also obtained from the surrounding academic environment, which is related to the workspace environment in conducting Tridarma activities. The lecturer workspace is Tridarma's activities take place, it is also a space for lecturers to actualize themselves through their fields of expertise, science and works. The layout of the lecturers' workplaces related to scientific fields at the Faculty of Creative Industries differs from one another, due to the results of work activities, research carried out, and the resulting paperwork varies from dimension / size in the field of expertise / science. The standard of work space for lecturers in general is the same for all fields of science. This research method is carried out with a qualitative approach, starting by observing empirical facts about the working space of the lecturers in the Faculty of Creative Industries, and then explaining the existing conditions and analyzing in accordance with applicable standards. The results & findings of this study conclude that the activity patterns and layout in the Tel-U lecturer workspace at the Faculty of Creative Industry are associated with the field of knowledge of each study program have the same cubical pattern and facilities, with a centralized orientation circulation in the middle of the room, there is no no special work storage space.

Selection Of

Best value PIPS has been introduced in the Netherlands in the procurement of construction systems. The Water Board De Dommel utilized best value PIPS to select engineering consultant services. The test differed from other Dutch tests in that the PIPS process used the pre-award phase before the award phase. The best value selection of engineers also proposes that design firms can compete on value (price and performance). The engineering selection process was much closer to the original BVP/PIPS than the construction phases. The major lesson learned is the BVP/PIPS is a paradigm shift. The success of the test led to the recommendation of more professional services using BVP/PIPS.

Shed Light

While reviewing SME succession literature, an empirical dearth in internal non-family SMEs succession research was detected. This situation is somewhat surprising considering the demographic developments and the fact that in many countries (e.g. Belgium and the Netherlands) the majority of business transfers are actually non-family. In this chapter, internal non-family succession is explored in a smaller Austrian company to shed light on how the firm is preparing for this type of succession. With regard to succession preparation, insights into the aspects of successor selection, successor training, employee involvement in the succession process, and performance measurement systems are provided. The findings this chapter reports may be useful for both academics and practitioners.
