In evidence-based weight-loss programs weight regain is common after an initial weight reduction. Eating slowly significantly lowers meal energy intake and hunger ratings. Despite this knowledge, obese individuals do not implement this behaviour. We, thus tested the hypothesis of changing eating behaviour with an intra-oral medical device leading to constant weight reduction in overweight and obesity.
Six obese patients (6 men, age 56 ± 14, BMI 29 ± 2 kg / m2) with increased CVRF profile were included in this prospective study. All patients had been treated for obesity during the last 10 years in a single centre and had at least 3 frustrate evidence-based diets. Patients received a novel non-invasive intra-oral medical device to slow eating time. Further advice included not to count calories, to avoid any other form of diet, to take their time with their meals, and to eat whatever they liked.
This device was used only during meals for the first 4 to 8 weeks for a total of 88 [20–160] hours. Follow-up period was 23 [15–38] months. During this period, patients lost 11% [5–20%] (p<0.001) of their initial weight. At 12 months, all patients had lost >5%, and 67% (4/6) achieved a >10% bodyweight loss. In the course of the study, altered eating patterns were observed. There were no complications with the medical device. Of note, all patients continued to lose weight after the initial intervention period (p<0.001) and none of them had weight regain.
With this medical device, overweight and obese patients with a history of previously frustrating attempts to lose weight achieved a significant and sustained weight loss over two years. These results warrant the ongoing prospective randomised controlled trial to prove concept and mechanism of action.
Im Interview mit Dr. Anne Hardy wagt RMV-Stiftungsprofessor Martin Lanzendorf einen Blick in die Zukunft: Die flexible, zweckangepasste Wahl von Verkehrsmitteln ist die Regel und wird durch die Vernetzung mit Smartphones erleichtert, Radfahrer und Fußgänger erobern die Straße zurück – und die Goethe-Universität entwickelt neue Initiativen im Mobilitäts- und Energiemanagement.
The organisation of parking is a key challenge to more sustainable mobility in urban areas, as its pricing and availability affect the rates of private car ownership and use. However, changing parking policies is a challenging issue for local politicians and planners because residents frequently oppose changes or restrictions to conditions they have taken for granted such as on-street parking in a public space. The aim of this paper is firstly to assess how the parking policy of an urban neighbourhood can be structured to contribute to more sustainable mobility and to increase liveability in the neighbourhood. The second aim is to apply the policies reviewed to an example neighbourhood. For this purpose, we systematically reviewed academic literature and identified five types of relevant parking policies: (i) maximum parking requirements, (ii) physical detachment of residence and parking space, (iii) residential parking permits and the limitation of available parking space, (iv) performance-based pricing and (v) parking as a demand management strategy. We discovered that most research focuses on econometric models about parking and that studies rarely address the effects of parking on the quality of life in neighbourhoods. Therefore, we need further research regarding the relationship of parking and liveability. We conclude that for the implementation of such parking policies in an example neighbourhood, the municipality needs to develop a mobility vision for its city. It has to understand parking as a tool for transportation demand management to increase the acceptance of parking policy concepts and to avoid spillover problems. Finally, in the German case, as in most other countries, states and municipalities need to redesign their legal frameworks to be able to manage parking supply better and to react to changes related to digital developments and parking. The findings have implications for other European neighbourhoods regarding the transfer from research to local circumstances and applications for the whole city.
Support for innovative on-street parking policies: empirical evidence from an urban neighborhood
(2020)
Municipalities and planners often hesitate to implement restrictive parking policies because residents regularly oppose any changes to on-street parking space. Residential parking is one key factor of parking management because its location and availability influence a household's car ownership and use. Moreover, as more residents regularly use other means of transportation that need space and infrastructure in the urban realm, and as parking takes up a vast amount of land, municipalities are considering the reuse of on-street parking space for other purposes. As public acceptability is a precondition for the successful implementation of a proposed policy, our empirical analysis investigates to what extent residents support restrictive and demand-oriented on-street parking policies in the dense, highly urbanized neighborhood of Frankfurt-Bornheim, Germany (N = 1027). Surprisingly, despite some variations, the majority of the residents in our survey are in favor of the policy options suggested. Support for the demand-oriented policies (extension of bicycle infrastructure, improved sharing supply and mobility hubs, neighborhood garages, and improved public transit supply) is higher than the acceptance of the restrictive policies, and of policies that are a combination of restrictive and demand-oriented policies. However, surprisingly, a majority is still in favor of many of these (extension of parking fees and parking restrictions, and reuse of parking space for better livability). Furthermore, we classify residents who live in a household with private cars into the stage model of self-regulated behavior change to analyze their intention towards a reduction in private car use. Results from linear regression analyses indicate that residents who have intentions to change their behavior towards car use reduction assess the policy options more similarly to car-free households and regular bike users, and not like the other car-owning households. The findings suggest that while the residents support financial-related policies the least, they are more receptive towards parking policies than policy makers and planners assume if the reuse of parking lots creates space for other users or if it increases the quality of life, for instance, by adding bike lanes, wider sidewalks or greenery. Hence, a combination of restrictive and demand-oriented on-street parking policies results in high acceptance among residents, and the communication from municipalities regarding the implementation of the different policies needs to vary depending on the kind of household.
Financial poverty, mobility and social participation are interrelated. This nexus makes old-age poverty a highly relevant issue in terms of transport-related social exclusion in an ageing society. To understand how financial poverty affects older people’s travel practices and how they cope with their limited financial resources, we conducted qualitative interviews with low-income older people (aged 60 and above) in Ronnenberg (Hanover region, Germany). Although all the respondents have comparably limited financial resources, using a practice theory perspective along the elements of materials, competences and meanings (Shove et al., 2012), we identified three different types of low-income older people by their travel practices: (i) active older people with multifaceted social interactions, (ii) neighbourhood-oriented older people with local interactions and (iii) home-centred older people with few social interactions. From our analysis, we conclude that financial poverty shapes each element of low-income older people’s travel practices and thereby increases the risk of transport-related social exclusion: (i) certain materials have to be financed, which is challenging or even impossible due to financial poverty; (ii) meanings of travel practices are strongly linked to other practices, thus, if (also for financial reasons) no or a limited range of destinations are mentioned, travel practices are restricted in their frequency and distance; and (iii) necessary competences to be mobile and engage in social activities despite low financial means seem to be differentially available or - more cautiously formulated – less often utilised by low-income older people, which may lead to them abandoning travel practices and related social activities.
In recent years, many European cities have developed strategies to improve the quality of urban life by reducing car traffic and increasing the attractiveness of alternative modes and the built environment for residents. Frequently, at least in German cities, improvements to the cycling infrastructures play a key role in this transformation of urban spaces. One of those transformative interventions took place in 2020 in Frankfurt am Main (Germany). The city redesigned an arterial road close to the city centre, the Friedberger Landstrasse, by converting two car lanes to bicycle lanes. It is the aim of this study to analyse the effects of this change on the quality of urban life of its residents using a quantitative before-and-after study. The results demonstrate the expected improvements in the perceived quality of urban life for residents after the intervention. A more detailed analysis, however, shows that the residents’ perceptions vary according to their own mode use on the Friedberger Landstrasse and other sociodemographic characteristics. Thus, better cycling infrastructure does not only improve conditions for cyclists, but also contributes to a higher quality of urban life for residents and, therefore, improves the liveability of a city in two ways. We conclude that local transport policies are not only relevant for a modal shift, but also for the quality of urban life and, thus, related urban development strategies.

Abstract
To promote non-motorised travel, many travel behaviour studies acknowledge the importance of the built environment to modal choice, for example with its density or mix of uses. From a mobility design theory perspective, however, objects and environments affect human perceptions, assessments and behaviour in at least three different ways: by their practical, aesthetic and emblematic functions. This review of existing evidence will argue that travel behaviour research has so far mainly focused on the practical function of the built environment. For that purpose, we systematically identified 56 relevant studies on the impacts of the built environment on non-motorised travel behaviour in the Web of Science database. The focus of research on the practical design function primary involves land use distribution, street network connectivity and the presence of walking and cycling facilities. Only a small number of papers address the aesthetic and emblematic functions. These show that the perceived attractiveness of an environment and evoked feelings of traffic safety increase the likelihood of walking and cycling. However, from a mobility design perspective, the results of the review indicate a gap regarding comprehensive research on the effects of the aesthetic and emblematic functions of the built environment. Further research involving these functions might contribute to a better understanding of how to promote non-motorised travel more effectively. Moreover, limitations related to survey techniques, regional distribution and the comparability of results were identified.
Viele Städte in Deutschland stehen aktuell vor komplexen ökonomischen, ökologischen und sozialen Herausforderungen, die mit klassischen ressortbezogenen Planungskonzepten nicht zu bewältigen sind. Integrierte Stadtentwicklungskonzepte erleben deshalb vielerorts eine Renaissance in der städtischen Planungspraxis. Die in diesem Zusammenhang diskutierten Planungsleitbilder geben jedoch nur selten direkt umsetzbare Handlungskonzepte vor. In diesem Beitrag werden deshalb am Beispiel der Stadt Leipzig konkrete Handlungsoptionen für eine an nachhaltiger Mobilität orientierte Stadtentwicklung vorgestellt. Aufbauend auf bisherigen Erkenntnissen zu integrierten Stadtentwicklungskonzepten werden zunächst infrastrukturbezogene Konzepte zur Förderung des Wohnens im Innenbereich, zur Stärkung städtischer Zentren sowie zur Förderung der Nahmobilität dargestellt. Darüber hinaus werden auch politische, organisatorische und kommunikative Handlungsoptionen aufgezeigt. Diese umfassen Maßnahmen zur Verbesserung der übergeordneten Rahmenbedingungen, Konzepte zur Stärkung der inter- und intrakommunalen Kooperation sowie integrierte städtische Mobilitätskonzepte. Das Beispiel Leipzig macht dabei deutlich, dass infrastrukturelle Ansätze für eine an nachhaltiger Mobilitätsgestaltung orientierte Stadtentwicklung nicht ausreichend sind. Vielmehr ist eine bessere Abstimmung der Stadt- und Verkehrsplanung auf die Bedürfnisse der Bevölkerung erforderlich; dazu gehört auch die Integration von Mobilitätsmanagementmaßnahmen in städtische Verkehrskonzepte. Für eine wirksame Umsetzung integrierter Stadtentwicklungskonzepte erscheinen außerdem eine an Nachhaltigkeitszielen orientierte Gestaltung der rechtlichen und politischen Rahmenbedingungen sowie eine stärkere Berücksichtigung regionaler Verknüpfungen in städtischen Planungen notwendig.
During the last 15 years most central and east european countries faced an era of institutional, economic and demographic transition. With the fall of the wall and the end of the Soviet Union, the former socialist countries transformed their political, economic and social institutions; today, some of them are already a member state of the European Union. The re- unificated Germany was not only affected by this process in its eastern part, the former German Democratic Republic (GDR), where the political and institutional structures were entirely exchanged; with the end of the “Rheinische Bundesrepublik”, the incarnation of a welfare and growth oriented Fordist society, also former West Germany had to adapt to this transition and still is facing a process of institutional modernisation.
