Does the Use of Mobile Devices (Tablets and Smartphones) Affect Stated Choice Behavior in Web Surveys? An Application to Environmental Valuation

Web surveys are becoming increasingly popular in survey research. Compared with face-to-face, telephone and mail surveys, web surveys may contain a different and new source of measurement error and bias: the type of device that respondents use to answer the survey questions. To the best of our knowledge, this is the first study that tests whether the use of mobile devices affects survey characteristics and stated preferences in a web-based choice experiment. The web survey was carried out in Germany with 3,400 respondents, of which 12 per cent used a mobile device (i.e. tablet or smartphone), and comprised a stated choice experiment on externalities of renewable energy production using wind, solar and biomass. Our main finding is that survey characteristics such as interview length and acquiescence tendency are affected by the device used. In contrast to what might be expected, we find that, compared with respondents using desktop computers and laptops, mobile device users spent more time to answer the survey and are less likely to be prone to acquiescence bias. In the choice experiment, mobile device users tended to be more consistent in their stated choices, and there are differences in willingness to pay between both subsamples.

Stuck in Mobility? Fragmented Journeys of Migrants without Chances of Admission in Europe

This paper is about young migrants without chance of being granted legal residence status in the Schengen zone. Previous observations suggest that some migrants, whose country of origin leaves them with low chances of receiving asylum or in fact any type of residence permit, exhibit a highly complex migration pattern that is characterised by 1) durable “transit” across Europe, which is a multi-linear movement according to opportunities that open up along the journey; 2) a high degree of flexibility, as they have to respond to suddenly changing conditions, such as work opportunities, rejection of asylum claims, detention or deportation, and 3) switching between different legal statuses, such as asylum seeker, sans papiers or detainee. The experiences of these young adults thus show a deep ambivalence between a sense of autonomy, on the one hand, and of profound hope and powerlessness, on the other. The Dublin Convention intends to limit such a hypermobility of migrants but seems to fail in many cases. Simultaneously it provokes some of the movements by sending asylum seekers and irregular migrants back to their first country of arrivals. Given the fact that little is known about these fragmented journeys inside of the Schengen area, this ethnographic study produces novel data on a highly pertinent migration pattern, the impact of the European migration management on individual migrants as well as the inter-relatedness of the asylum regime and irregular migration in Europe. At the same time these fragmented journeys are an excellent example to discuss mobility as a resource on the one hand (since it enables this specific migrant group to extend their presence in Europe) and as a handicap on the other (since it impedes the building of stable social networks, the planning of the future, etc.).

Kriegsverbrechen – Verbrechen gegen die Menschlichkeit – Völkermord? Zeitgenössische Völkerrechtler und die Deportation der christlichen Minderheiten in Anatolien während des Ersten Weltkrieges

This presentation concentrates on the role that the deportation of Christian minorities in Anatolia during the First World War played in the context of the history of law. Terminologies and the use of legal notions by contemporaries will be a special focus, because this is still helpful in the context of present-day discussions. Therefore a contextualisation as precise as possible is important, when the topic of deportation and genocide is addressed. At the same time it is important not to confuse historical and legal appraisals. In this presentation the general discussion as to the prospects and potential of a judicial punishment of violations of international legal norms before as well as during the First World War will therefore be included as much as the attitude of jurists in regard to the position of the Ottoman Empire within the international community of law abiding states. Finally this presentation will also focus on discussions at the end of the war around the trials in Istanbul and the purpose of the Paris Peace Conference. In this context and following ideas of Mahmood Mamdani the discourse on law can be shown to have served not only as a way of giving victims a voice, but also as a language of power already at the beginning of the 20th century.
