Comparative Politics: An Introduction
No full textBook DescriptionA modern, up-to-date and extremely well written new introductory text, written by an experienced author and specialist in the field. The approach hangs around the three main themes of liberalization, globalization and democratization. From the Back Cover"Politics is not just a game. It is the ultimate game" Comparative Politics takes a truly international approach to the study of different political systems. Using a clear analytical framework and focusing on three key concepts: democratisation, liberalisation and globalisation, Comparative Politics explains how governments and political establishments gain, exercise and maintain power. Case studies and examples of different types of government from around the world vividly illustrate the text. Not only liberal democracies, but authoritarian and military systems are considered, and the impact of new social movements, and their opposition to the centralisation of power is also explored. Key features: * Global perspective * Clear and distinctive analytical framework * Three themes: democratisation, liberalisation and globalisation * 12 case studies to illustrate key aspects * Brief analyses of 22 leading countries * Sample examination questions * Broad bibliography and suggestions for further reading *Supporting webside material - see p.vii Peter Calvert has been Professor of Comparative and International Politics at the University of Southampton since 1984. He has more than forty years teaching experience at University level, is the author, co-author or editor of some thirty books and has since 1996 been co-editor of the journal Democratization
Eliza Calvert Hall: Kentucky Author and Suffragist
No full textIn 1907, the author, poet, essayist, and folk art historian Eliza Calvert Hall (1856–1935) published Aunt Jane of Kentucky, a collection of stories about rural life infused with the spirit and gentle good humor of its elderly narrator, Aunt Jane. The book and several sequels achieved wide popularity and placed Hall in the front ranks of “local color” fiction writers of her time. As Hall struggled to balance her writing career with the duties of a nineteenth-century wife and mother, suffragist Laura Clay was lobbying for every woman’s right to vote. Hall joined the battle, writing fearlessly in support of suffrage and equality. While her passionate essays served as a direct appeal for this cause, her creative writing also carried a feminist spirit, celebrating the strength, humor, love, and art of the common woman. In Eliza Calvert Hall, Lynn E. Niedermeier tells the story of this remarkable Kentucky woman for the first time.
Supplies a valuable history of the women\u27s rights movement in Kentucky, and also introduces the reader to an overlooked author of compassionate and witty fiction. -- Bonnie Jean Cox, former director of the University of Kentucky\u27s Women and Gender Studies programhttps://digitalcommons.wku.edu/dlsc_books/1000/thumbnail.jp
From Pedrolino to a Pierrot: The Origin, Ancestry and Ambivalence of the British Pierrot Troupe
No full textIn this article, the author considers the British development of the seaside Pierrot troupe, arguing that its construction is consistent with the notion of invented tradition, and the associated concerns with identity and nationality. Tracing the history of the character from its origins as Pedrolino in the commedia dell’arte, the article considers the traditional and novel elements of the British form. This also allows a brief account of the origin and aesthetics of the British tradition. Reflecting on the synthesis of the archaic and contemporary dimensions of the form, the author proposes that the new structure constructed an ambivalent class of character. The composition of both troupes and audiences was drawn from across the range of social strata. Through its collectivity and its treatment of contemporary social themes, it is argued the British Pierrot troupe approached and negotiated questions of a cultural and national identity in the late-Victorian period.

Stochastic macroscopic analysis and modelling for traffic management
No full textWhen congestion becomes a problem on a road or road network, there are generally three main solution areas available to tackle it: construction, pricing or traffic management. Traffic management became an increasingly preferred option towards the end of the twentieth century as an alternative to construction in many cases. Traffic management proves a more efficient alternative and focusses on influencing traffic flows such that the existing road and network capacity is more effectively utilised resulting in a reduction in congestion. The effectiveness of traffic management is dependent on the ability to influence traffic flow. However, traffic contains a relatively large amount of stochastic behaviour, which is connected to human driving behaviour. The fluctuations that occur in traffic flow due to this stochastic behaviour have a large effect on the effectiveness of traffic management. Furthermore, uncertainty between time dependant scenarios has also shown to have a large influence on the outcome of the analysis of traffic management measures. In the past, little attention has been paid to these effects. Therefore, the main objective of this thesis is to give insight into the stochastic fluctuations and uncertainty in traffic flow for the application of traffic management measures and to propose tools that allow these effects to be analysed and subsequently modelled in aggregated macroscopic flows. In doing this, the necessity to consider uncertainty and fluctuations for traffic management is also demonstrated. Stochastic processes are considered as uncertainty, which describes day-to-day uncertainties between traffic flows, and fluctuations, which describes microscopic variability in the traffic flow. Three main areas are focussed on: the analysis of variations in traffic, modelling fluctuations and uncertainty in traffic, and the visual communication of uncertainty from traffic models
Communicatie van model onzekerheden: Meer of minder?
No full textHet is al langer bekend dat onzekerheid een belangrijke rol speelt in het verkeer net als in de wereld om ons heen. Dit geldt zowel op een strategische lange termijn basis als op de operationele basis in verkeersdynamiek. Er geldt echter een onbekendheid en misschien zelfs een onwil om voldoende rekening te houden met onzekerheden. Een belangrijke drempel om er goed mee om te gaan ligt bij de kwantiteit, maar ook de kwaliteit van de communicatie over onzekerheden. In dit debat paper wordt het probleem aangekaart dat het verkeerskundigen niet goed lukt om de belangrijkste onzekerheden te communiceren met beleidsmakers. Er worden zowel voor- als tegenargumenten gegeven, waarna er stelling wordt genomen dat het noodzakelijk is om bij modelstudies meer onzekerheid te communiceren richting beleidsmakers.Transport & PlanningCivil Engineering and Geoscience
A methodology for prediction accuracy assessment of intelligent traffic signal control algorithms with SPaT messages
No full textNew smart traffic signal control algorithms are capable of predicting the traffic signal state (red, green, or amber) changes, which can be provided to users to achieve more efficient traffic flow. However, these predictions pose an uncertain impact on the traffic flow and safety depending upon the quality of prediction. The information regarding the current state as well as the predicted residual time of state is communicated to other users in the form of Signal Phase and Timing (SPaT) data. In this paper, the SPaT message data is analyzed from an on-road pilot of different traffic signal control algorithms on provincial roads in the Province of North Holland. For analysis, new methods and indicators for quantification of prediction accuracy and quality of algorithm are proposed. These indicators can either be used for correction of state change prediction in real-time or for comparative analysis of the performance of different traffic signal control algorithms. This paper presents three main findings. First, it is found that a half fixed algorithm has very high prediction accuracy up to 99% for optimized directions. Second, the prediction accuracy of Time to Amber predictions improved by around 30% with this algorithm. Third, the overall reliability of prediction always increased with the use of the algorithmAccepted Author ManuscriptTransport and Plannin
