    This paper describes a study of the transport and accessibility needs of residents living in low-income communities in the City of Recife in Brazil. It discusses the theoretical background underpinning the academic and policy rationale for such a study. We outline the qualitative methodological approach, which was adopted to engage in meaningful knowledge exchanges with what are often considered by policymakers to be the ‘hard-to-reach’ citizens of Brazil’s favelas. In the exploration of our study results, we describe the complex relationship between the mobilities and livelihoods of the research participants. A key question the paper seeks to examine is how far the restricted mobility and activity patterns of citizens in these low-income communities influences or interacts with their quality of life outcomes in terms of their wealth, health and wellbeing? A second question is whether transport planning and policy can have a role to play in enhancing their future life chances? Currently, transport planners and policymakers in Brazil know very little about the specific accessibility and mobility needs of people living in Brazilian low-income communities. Our aim is to shed some light on the issue of their mobility needs in the context of a wider set of policy discussions about how to protect the livelihoods and wellbeing of low-income populations within rapidly emerging urban economies

    Specifying, Estimating and Validating a New Trip Generation Model: Case Study in Montgomery County, Maryland

    This paper discusses the development of an afternoon peak period trip generation model for both work and non-work trips. Three data sources are used in model development, a Household Travel Survey, a Census-Update Survey, and a Trip Generation Study. Seven one-direction trip purposes are defined, specifically accounting for stops made on the return trip from work to home. Trips are classified by origin and destination activities rather than by production and attraction, so reframing the conventional schema of home-based and non-home-based trips. Prior to estimating the model, the Household Travel Survey was demographically calibrated against the Census-Update to minimize demographic bias. A model of home-end trip generation is estimated using the Household Travel Survey as a cross-classification of the demographic factors of age and household size in addition to dwelling type. Non-home-end generation uses employment by type and population. The model was validated by comparison with a site based Trip Generation Study, which revealed an under-reporting of the relatively short and less regular shopping trips. Normalization procedures are developed to ensure that all ends of a chained trip were properly accounted for. .

    The Berlin Brain-Computer Interface: Progress Beyond Communication and Control

    Get PDF
    The combined effect of fundamental results about neurocognitive processes and advancements in decoding mental states from ongoing brain signals has brought forth a whole range of potential neurotechnological applications. In this article, we review our developments in this area and put them into perspective. These examples cover a wide range of maturity levels with respect to their applicability. While we assume we are still a long way away from integrating Brain-Computer Interface (BCI) technology in general interaction with computers, or from implementing neurotechnological measures in safety-critical workplaces, results have already now been obtained involving a BCI as research tool. In this article, we discuss the reasons why, in some of the prospective application domains, considerable effort is still required to make the systems ready to deal with the full complexity of the real world.EC/FP7/611570/EU/Symbiotic Mind Computer Interaction for Information Seeking/MindSeeEC/FP7/625991/EU/Hyperscanning 2.0 Analyses of Multimodal Neuroimaging Data: Concept, Methods and Applications/HYPERSCANNING 2.0DFG, 103586207, GRK 1589: Verarbeitung sensorischer Informationen in neuronalen Systeme

    The integration of contact by impact verbs into the intransitive motion construction

    The present investigation will analyze the lexical-constructional integration of contact by impact verbs (transitive by origin) into the intransitive-motion construction. Departing from the classical works by Levin (1993), Goldberg (1995) and Faber and Mairal (1999) on contact by impact verbs, I will propose a new taxonomy that overcomes the weaknesses of previous classifications and discuss the constructional use of these verbs in real language data. Finally, I will explain the compatibility of such verbs with the intransitive-motion construction following the explanatory tools provided by the Lexical Constructional Model (Ruiz de Mendoza and Mairal, 2008a, 2008b, 2011). The main conclusions that derive from this study are that most contact-by-impact verbs are compatible with the intransitive-motion construction, this integration being possible by applying different high-level metaphors and metonymies and that all contact-by-impact verbs that are related to sound (batter, bump, crack,
) are licensed into the intransitive-motion construction thanks to the use of the high-level metonymy RESULT FOR ACTION, in which the resulting sound is taken as the action performed by the subject
