    This paper is concerned with the development of a conceptual framework that measures the resilience of the transport network under climate change related events. However, the conceptual framework could be adapted and quantified to suit each disruption’s unique impacts. The proposed resilience framework evaluates the changes in transport network performance in multi-stage processes; pre, during and after the disruption. The framework will be of use to decision makers in understanding the dynamic nature of resilience under various events. Furthermore, it could be used as an evaluation tool to gauge transport network performance and highlight weaknesses in the network. In this paper, the system dynamics approach and fuzzy logic theory are integrated and employed to study three characteristics of network resilience. The proposed methodology has been selected to overcome two dominant problems in transport modelling, namely complexity and uncertainty. The system dynamics approach is intended to overcome the double counting effect of extreme events on various resilience characteristics because of its ability to model the feedback process and time delay. On the other hand, fuzzy logic is used to model the relationships among different variables that are difficult to express in numerical form such as redundancy and mobility

    A network mobility indicator using a fuzzy logic approach

    This paper introduces a methodology to assess the mobility of a road transport network from the 3 network perspective. In this research, the mobility of the road transport network is defined as the 4 ability of the road transport network to connect all the origin-destination pairs within the network with 5 an acceptable level of service. Two mobility attributes are therefore introduced to assess the physical 6 connectivity and the road transport network level of service. Furthermore, a simple technique based 7 on a fuzzy logic approach is used to combine mobility attributes into a single mobility indicator in 8 order to measure the impact of disruptive events on road transport network functionality. 9 The application of the proposed methodology on a hypothetical Delft city network shows the ability of the technique to estimate variation in the level of mobility under different scenarios. The method allows the study of demand and supply side variations on overall network mobility, providing a new tool for decision makers in understanding the dynamic nature of mobility under various events. The method can also be used as an evaluation tool to gauge the highway network mobility level, and to highlight weaknesses in the network

    Writing Creatively in First Grade

    Learning to write their own words increases students\u27 success in learning to read, provides practice in thinking skills, increases their self-concept and provides early positive attitudes about writing. However, most writing done in first grade classrooms today consists mainly of copying from the blackboard. This is a tedious and boring task for first graders, and gives them bad attitudes about writing as they begin their school careers. Many teachers don\u27t require young students to write their own words because of the students\u27 inability to spell words and form grammatically correct sentences. However, if a teacher is accepting of the students\u27 imperfect spelling and grammar, the students will feel free to express their thoughts on paper. This project provides a year long curriculum design along with the activities necessary to teach first grade students to write creatively

    Young America: The Transformation of Nationalism before the Civil War

    Mark Power Smith examines how mid-nineteenth-century European liberal nationalist movements affected United States’ nationalism(s), especially as configured by the Young America bloc of the Democratic Party. Smith finds that Europeans\u27 embrace of \u27more interventionist forms of liberalism,\u27 such as socialism, or abolitionism, \u27made popular resistance to interventionism a conservative, rather than radical force.\u2

    In Minnesota, reforms to post-release supervision for those leaving prison have been a cost-effective solution

    Get PDF
    In Minnesota, corrections authorities have used a program known as intensive supervised release (ISR) to monitor some of those who leave prison in the state. In new research Grant Duwe and Susan McNeeley examine the effects of recent reforms to the program which take into account the risk of reoffending by those released. They find that, compared to standard supervision, the new program reduced reoffending, and was cost-effective

    Analysing ride behaviours of shared e-scooter users – a case study of Liverpool

    Full text link
    [EN] The shared e-scooter is a relatively new form of Micromobility service in urban transit. A better understanding of the use of the scheme will help operators and stakeholders promote this travel mode, contributing to a more sustainable, resilient, environmentally friendly and inclusive transportation system. The availability of high resolution sensor-based location data, when co-analysed with socio-demographic survey data allows insights on where, how, and by whom the service is used. This study focuses on analysing the usage pattern of a recently introduced shared e-scooter scheme in Liverpool, UK, combining survey data of users’ sociodemographic attributes and their full trip records at a fine spatiotemporal granularity. Recency-Frequency (RF) segmentation is used to categorise user behaviour based on their frequency and recency of usage, and a Functional Signatures (FS) dataset is used to enrich contextual information on the origin and destination of e-scooter trips. Overall, this study provides insights into the behaviour of users of shared e-scooters and how the behaviours might vary in different user groups regarding sociodemographic characteristics. The developed analysis framework is also readily transferable to other cities.This research has been sponsored by the Alan Turing Institute under grant number R-LEE006.Yang, Y.; Grant-Muller, S.

    Toward a creative-critical approach to narratives of student-to-student abuse in Canada’s Indian Residential School System

    Get PDF
    There is a dearth of research on student-to-student abuse in Canada’s Indian Residential School System despite the fact that the legacy of this violence continues to negatively impact Indigenous communities. This paper proposes an approach to dealing with this difficult subject matter by using creative practice as a means of working collectively with community leaders, scholars, artists and students to develop shared understandings of the abuse and its continued legacy. This paper outlines the rationale for work in this area and the beginnings of the development of hybrid Indigenous and non-Indigenous methodology that brings survivors’ stories to audiences through a series of collectively authored theatrical performances that promote understanding and dialog. This paper is of interest to scholars, artists, playwrights, community leaders, and front line social workers who are working to bridge academic research and community engagement, particularly as it relates to artistic practice
