Flexible work arrangements and household-related journeys. Who takes the lead in dual-earner heterosexual couples?

2022

International audience; This research provides an exploration of the relationship between flexible work arrangements (FWA), CO2 emissions, and household travel allocation among dual-earner couples. Using data from the United Kingdom National Travel Survey for the period between 2002 and 2017, we develop a path analysis approach based on SEM that allows for a comprehensive study of travel behavior and trade-off effects. Results suggest that, although the partner who benefits from FWAs tends to carry out domestic provision and maintenance activities, the allocation of tasks within the household is still asymmetrical. Results also outline that the presence of children will intensely affect the…

An attraction-based cellular automaton model for generating spatiotemporal population maps in urban areas

2015

We develop a cellular automaton (CA) model to produce spatiotemporal population maps that estimate population distributions in an urban area during a random working day. The resulting population maps are at 50 m and 5 minutes spatiotemporal resolution, showing clearly how the distribution of population varies throughout a 24-hour period. The maps indicate that some areas of the city, which are sparsely populated during the night, can be densely populated during the day. The developed CA model assumes that the population transition trends follow dynamics and propagation patterns similar to a contagious disease. Thus, our model designed to change the states of each grid cell (stable or dynami…

Investigating Mobility Gaps in University Campuses

2018

The objective of the present research is to carry out a gap analysis between current mobility situations and the needs, future plans and priorities regarding a number of thematic areas on the issue of mobility in university campuses. For this purpose, an interview was conducted involving 36 experts from seven Southern European Universities. More specifically, experts from each university were asked to analyse and rate both the current and the desired situation in the campus under their responsibility with focus on the following thematic areas: parking management, soft modes infrastructure, public transport, car related issues, road infrastructure, environment and energy, mobility management…

Estimating the dwarfing rate of an extinct Sicilian elephant.

2021

Summary Evolution on islands, together with the often extreme phenotypic changes associated with it, has attracted much interest from evolutionary biologists. However, measuring the rate of change of phenotypic traits of extinct animals can be challenging, in part due to the incompleteness of the fossil record. Here, we use combined molecular and fossil evidence to define the minimum and maximum rate of dwarfing in an extinct Mediterranean dwarf elephant from Puntali Cave (Sicily). 1 Despite the challenges associated with recovering ancient DNA from warm climates, 2 we successfully retrieved a mitogenome from a sample with an estimated age between 175,500 and 50,000 years. Our results sugge…

Comparison of quantitative Holocene temperature reconstructions using multiple proxies from a northern boreal lake

2017

Four biotic proxies (plant macrofossils, pollen, chironomids and diatoms) are employed to quantitatively reconstruct variations in mean July air temperatures ( Tjul) at Lake Loitsana (northern Finland) during the Holocene. The aim is to evaluate the robustness and biases in these temperature reconstructions and to compare the timing of highest Tjul in the individual reconstructions. The reconstructed Tjul values are evaluated in relation to local-scale/site-specific processes associated with the Holocene lake development at Loitsana as these factors have been shown to significantly influence the fossil assemblages found in the Lake Loitsana sediments. While pollen-based temperatures follow…
