Die Möglichkeit zur multilokalen Lebensführung (ML) hängt von der Erreichbarkeit der Wohnstandorte relativ zueinander ab. Diese wiederum ergibt sich aus der zu überwindenden Distanz und den Verkehrsangeboten (Infrastrukturen und Services). Die spezifischen Ansprüche multilokal lebender Personen sind von ihrem Mobilitätsverhalten bestimmt, das wiederum teilweise von den miteinander verbundenen Orten abhängt (z.B. Stadt/Stadt oder Stadt/Land). Zu unterscheiden ist weiterhin zwischen lokalen und regionalen Verkehrsangeboten an den Wohnorten und Reisen zwischen den Wohnorten. Auch der öffentliche Charakter der meisten Verkehrsangebote macht die Anforderungen multilokal Lebender an Verkehrsplanung und politik schwer bestimmbar. Sie können spezifisch werden, wenn Verkehrsangebote etwa mit Wohnangeboten für Multilokale verbunden werden, sich an bestimmte Gruppen multilokaler Personen richten oder besondere lokale Bedingungen vorliegen (z.B. Tourismusregionen).

Potential influences on explaining walking distance from home to access public transport are investigated, including trip and demographic characteristics and public transport supply. In Sydney, Australia, people walk farther to the train than to the bus, the distributions of walking distances are different for each mode, and the trip and demographic characteristics of train and bus users are different. Given the decision to walk to public transport, demographic characteristics such as age, gender, income, and labor force status and trip characteristics such as trip purpose, time of day and week, fare and ticket type, and trip duration are not significant in explaining walking distance to each mode of public transport. The mode of the public transport trip is the most important determinant of walking distance, reflecting the different supply and spacing of each mode. For instance, there are many more bus stops than train stations. The differences between train and bus users suggest that accessibility initiatives for public transport might not be the same for each mode.

This report is the output of the finalize toolkit phase (phase three) for the project sustainability toolkit for transport projects. The overall objective, as defined in the terms of reference, is 'to make development projects more sustainable by reducing the risk of failure of projects attaining their long-term development goals and enhance the prospects for their sustained impact on development ensuring that there is local commitment to longer-term buy-in'. The main deliverable of the project is a project sustainability toolkit, of which this report outlines the final version. This toolkit helps to gauge the potential for the project to be sustainable into the long-term and provide advice to help overcome common barriers to the successful development and implementation of projects. The guidance covers the expected opportunities and constraints related to sustainability. The toolkit is intended to reduce the risk of project failure in terms of sustainable development and enable recipient country clients to incorporate core sustainability principles into transport projects at every stage of project planning, design and delivery. This will improve the prospects for longer-term sustainability and will enhance the long-term impacts of development projects. Task Team Leaders (TTL's) will benefit from additional evidence that supports investments intended to consolidate long-term development, and borrowers will benefit from projects with improved and demonstrable longer-term beneficial impact. The toolkit provides general advice for transport sector investments and is not modally specific. Information on the sub-components of the key sustainability principles has not been included since it was considered that this did not add value or further understanding of the issues.

The impacts of climate change are already being observed in a variety of sectors and there is greater clarity that these changes are being caused by human activities, mainly through release of greenhouse gases. In 2005 the UK Government hosted the Avoiding Dangerous Climate Change conference to take an in-depth look at the scientific issues associated with climate change. This volume presents the most recent findings from the leading international scientists that attended the conference. The topics addressed include critical thresholds and key vulnerabilities of the climate system, impacts on human and natural systems, socioeconomic costs and benefits of emissions pathways, and technological options for meeting different stabilisation levels of greenhouse gases in the atmosphere. The volume provides invaluable information for researchers in environmental science, climatology, and atmospheric chemistry, policy-makers in governments and environmental organizations, and scientists and engineers in industry.

If you could be invisible, what would you do? The chances are that it would have something to do with power, wealth or sex. Perhaps all three. But there's no need to feel guilty. Impulses like these have always been at the heart of our fascination with invisibility: it points to realms beyond our senses, serves as a receptacle for fears and dreams, and hints at worlds where other rules apply. Invisibility is a mighty power and a terrible curse, a sexual promise, a spiritual condition. This is a history of humanity's turbulent relationship with the invisible. It takes on the myths and morals of Plato, the occult obsessions of the Middle Ages, the trickeries and illusions of stage magic, the auras and ethers of Victorian physics, military strategies to camouflage armies and ships and the discovery of invisibly small worlds. From the medieval to the cutting-edge, fairy tales to telecommunications, from beliefs about the supernatural to the discovery of dark energy, Philip Ball reveals the universe of the invisible
