Amidst the growing interest in enhancing the academic understanding of the relationships between e-shopping and transport, a key element remains underexplored – the impact of e-shopping on spatial accessibility to in-store retail. The paper studies variations in multimodal accessibility to in-store retail between e-shopper groups and the associated spatial effects. The research is based on a face-to-face questionnaire, administered in the city of Alcalá de Henares (Madrid Metropolitan Area, Spain), which provides data on socio-economic characteristics, e-shopping habits, and travel time preferences to reach in-store retail. Clustering techniques serve to identify three e-shopper groups: occasional e-shoppers with a car, infrequent e-shoppers with a car, and frequent e-shoppers without a car. A comparison of e-shopper distance-decay functions to reach in-store retail is made, revealing significant differences between the three e-shopper groups for car and public transport for any time interval. However, for walking such differences are limited to time intervals between 10 and 40 minutes. Distance-decay functions are processed through a gravity-based model, identifying three main multimodal accessibility places: highly resistant places to e-shopping, moderately resistant places, and vulnerable places. Places that are highly resistant to e-shopping are mainly located in the city centre, while vulnerable places are mostly found in the city’s periphery. The paper closes with concluding remarks on policymaking and a few pathways for future research.
Debates about climate-induced migratory movements – and their possible links to instability and conflict – along with the discussion on migration flows across the Mediterranean Sea frequently highlight the West African Sahel as a region of concern. However, findings from recent empirical research on Sahelian regions in Mali and Senegal suggest no evidence for increasing population movements towards Europe as a direct result of environmental stress and climate change. It is the patterns of migration that are changing and not so much the volume. A closer look at the social-ecological conditions of migration in the Sahel allows for an alternative characterization of the problem dynamics. It reveals a rich and comprehensive picture of mobility and the importance of climate and environment in this respect, and identifies starting points for policy options.
This paper will examine the self-reported division of housework and childcare in Germany and Poland considering the job-related spatial mobility within dual-earner couples who are living in a household together with a partner, using 2007 data from the Job Mobility and Family Lives in Europe Project. We find that men who are spatially mobile for work often report shifting housework to their partners. Polish couples show a stronger tendency toward an egalitarian division of labor than German couples do, especially in terms of childcare. But the central finding of this research is, gender trumps national differences and spatial mobility constraints. Polish and German women, whether mobile for their work or not, report doing the majority of housework and childcare compared to their partners.
Speolepta leptogaster (Winnertz, 1863) is frequently occurring in European subterranean environments. As for most cave animals, studies addressing non-anatomical aspects are sparse. Here we present the first molecular study on S. leptogaster. We investigated the demographic structure (i.e. COI locus) of 69 specimens from 36 underground populations in Hesse (Central German Uplands) to get first insights into the species’ dispersal ability.
In total, 14 haplotypes were revealed. Haplotype diversity was relatively high, whereas nucleotide diversity was low. Furthermore, a significant but low pattern of isolation-by-distance and (a) past population expansion event(s) were detected.
Our genetic results suggest a (good) active dispersal ability for Speolepta leptogaster. The occurrence of several surface records of adult specimens corroborates this hypothesis. We discuss the developmental stages of S. leptogaster in the context of the ecological classification system and regard the species as a eutroglophile. Evidence has been found to distinguish two larval types. A reconstructed life-cycle of the species is provided.
Even though tourism has been recognised as an important field for transnational research today, there are few attempts to place tourism in the context of transnational theories or to think about transnationalism from the perspective of tourists. I argue that in researching tourist practices one can add important aspects to transnational approaches. The prerequisites of mobility and interaction for example are the features chosen by backpackers to describe what their Round-The-World-Trip is about. A form of tourism is adopted, or created, that itself confronts many aspects of globalisation: First of all there is the immense dynamic that is involved. Backpackers try to cover as many places and experiences as possible, travelling at high speed. They adopt all kinds of touristic experiences ranging from beach to adventure to culture tourism. They don't focus on a specific area or country but travel the world. They cross national borders perpetually. Additionally they form a transnational network in which they interact with strangers of similar backgrounds (other backpackers, tourist professionals). This network helps them interacting with people from different backgrounds (the socalled hosts or locals). Considering my research Backpackers forge a certain identity from these transnational practices which I want to name globedentity. Globedentity expresses a type of identity construction that not only refers to the individual (I) but reflects the world (globe) in this identity. This globedentity is not fixed but is perpetually re-created and re-defined. It also embraces the increasing popular awareness of globalisation which backpackers, coming from highly educated middle class backgrounds, in particular have identified with. Due to the constant awareness of the latest global social, cultural and economic developments in these educated milieus they know exactly which tools to use to become successful parts of their societies.
