Over the years, several studies have been carried out to investigate how the statistics of annual discharge maxima vary with the size of basins, with diverse findings regarding the observed type of scaling (i.e., simple scaling vs. multiscaling), especially in cases where the data originated from regions with significantly different hydroclimatic characteristics. In this context, an important question arises on how one can effectively conclude on an approximate type of statistical scaling of annual discharge maxima with respect to the basin size. The present study aims at addressing this question, using daily discharges from 805 catchments located in different parts of the United Kingdom, with at least 30 years of recordings. To do so, we isolate the effects of the catchment area and the local rainfall climatology, and examine how the statistics of the standardized discharge maxima vary with the basin scale. The obtained results show that: (a) the local rainfall climatology is an important contributor to the observed statistics of peak annual discharges, and (b) when the effects of the local rainfall climatology are properly isolated, the scaling of the standardized annual discharge maxima with the area of the catchment closely follows that commonly met in actual rainfields, deviating significantly from the simple scaling rule. The aforementioned findings explain to a large extent the diverse results obtained by previous studies in the absence of rainfall information, shedding light on the approximate type of scaling of annual discharge maxima with the basin size.

Linda Colley (1996) identified three key ‘glues’ for the British Union state created in 1707: extensive wars with France; a uniting sense of Protestantism; and a burgeoning commercial and military empire. This article explores how two key parts of this project – namely, ‘unionism’ and a collective sense of ‘Britishness’ – has become increasingly disconnected in different parts of the United Kingdom. In particular, it examines the extent to which, following Colley's historical argument, white and Protestant citizens remain more likely to identify with political Unionism and Britishness as compared to other ethnic and religious groups. The discussion includes an analysis of the degree to which ‘feeling British’ and ‘valuing the Union’ overlap, and whether a connected unionism can be discerned against trends which increasingly place emphasis on the sub-state nation as a key political community of attachment and identity.

In the framework of the «Project I: CUD» (Internet: Creatively Unveiling Discrimination), carried out in the United Kingdom, Italy, Belgium, Romania and Spain, we conducted a study into the expressions of discrimination used by young people on social network sites (SNS). To do so we designed a methodological strategy for detecting discriminatory content in 493 Facebook profiles and used this strategy to collect 363 examples for further analysis. Our aims were to compile information on the various types of discriminatory content and how they function online in order to create tools and strategies that can be used by trainers, teachers and families to combat discrimination on the Internet. Through this study we have detected patterns between young men and young women that reveal that there is a feminine and a masculine way of behaving on the Internet and that there are different ways of expressing discrimination on SNS. Men tend to be more direct in their posting and sharing of messages. Their messages, which are also more clearly discriminatory, focus more on discrimination towards ethnic groups and cultural minorities. Women, on the other hand, tend to use indirect (reactive) discriminatory strategies with a less obvious discriminatory component that mainly focuses on sociocultural status and physical appearance. En el marco del Proyecto «I:CUD» (Internet: Desenmascarando la discriminación creativamente), llevado a cabo en el Reino Unido, Italia, Bélgica, Rumanía y España, hemos desarrollado una investigación sobre las expresiones de discriminación utilizadas por los jóvenes en las redes sociales (SNS). Para la realización de esta investigación, se ha diseñado una estrategia metodológica de detección de contenidos discriminatorios en 493 perfiles de Facebook que ha permitido encontrar 363 ejemplos para su análisis. El objetivo de la misma ha sido la obtención de información acerca de los tipos de contenidos discriminatorios y su forma de funcionamiento on-line, para facilitar la creación de herramientas y estrategias para luchar contra la discriminación en la Red, y su utilización por parte de formadores, docentes y familias. Como resultado, hemos detectado algunos patrones diferenciales entre hombres y mujeres jóvenes que nos permiten afirmar la existencia de una forma femenina y otra masculina de comportarse en Internet y un uso diferencial de las SNS en relación con la discriminación. En cuanto a ésta, los hombres tienden a tener más actividad directa (publicando y compartiendo mensajes), con contenidos más claramente discriminatorios y, sobretodo, centrados en la discriminación hacia grupos étnicos y minorías culturales. Las mujeres, por su parte, tienden a utilizar estrategias de discriminación no directas (reactivas), con una menor evidencia del componente discriminatorio. Ellas, mayoritariamente, dirigen las actitudes discriminatorias hacia la situación sociocultural y la apariencia física.

For a topic that until recently was presumed not to exist, English nationalism has transformed into an apparently obvious explanation for the Brexit result in England. Subsequent opinion polls have also raised doubts about the extent of continuing English commitment to the union of the United Kingdom itself. Yet, even as Englishness is apparently reshaping Britain’s place in the world and—perhaps—the state itself, it remains poorly understood, in part because of its unfamiliarity. It has long been assumed that nationalism is a feature of political life in the state’s periphery—Scotland, Wales, and Northern Ireland—but not its English core. Another barrier to understanding bas been the relative lack of public attitudes data with which to explore the nature of English nationalist sentiment.This book draws on data from a survey vehicle—the Future of England Survey—specially established in 2011 to facilitate the exploration of patterns of national identity in England and their political implications. On the basis of these data, Englishness offers new arguments about the nature and effect of English nationalism on British politics, as well as how Britishness operates in different parts of Britain. Crucially, it demonstrates that English nationalism is emphatically not a rejection of Britain and Britishness. Rather, English nationalism combines a sense of grievance about England’s place within the UK with a fierce commitment to a particular vision of Britain’s past, present, and future. Understanding its Janus-faced nature—both England and Britain, as it were—is key not only to understanding English nationalism, but also to understanding the ways in which it is transforming British politics.

This paper aims to study how an event, happening within a political community characterised by a high level of interdependence, has an impact on the defence policy of its members. To do so, the paper focuses on British-Polish defence relations after Brexit. Indeed, the United Kingdom signed a defence cooperation agreement (dca) with Poland in 2017, which is the second with an EU/nato Member State (MS) after the Lancaster House treaty signed with France. This case-study questions the thesis positing that dcas are unlikely to happen between EU/nato MS as it would lead to overlaps and decoupling. It also determines to what extent this treaty is part of a British strategy to re-create a security network in Europe after Brexit to deter Russia, which is considered as one of the main threats for both countries. Finally, this study deals with the political uses of history. The research analyses how British and Polish actors select memory mines to consolidate friendship in time of uncertainty but also as a shaming strategy.

This chapter examines what one government official called “an intelligence system of tsetse”—a thoroughly intrusive infrastructure and procedure of knowing this chipukanana (principally its mobilities) in the most complete way possible. This anthropomorphic formula for intrusive knowing sought “to live and breathe and think with” mhesvi; to do so entailed “a lifetime of affectionate study.” This meant placing a peripatetic chipukanana under surveillance, to know how much time it spent in different parts of the habitat at different times of the year; how much time it spent feeding, sleeping, or simply in vigilant mode, waiting to pounce on anything that moved. Maps—of where it slept, bred, roamed, ate; its boundaries; strong points and weak points—were essential to successful operations against it.

Poverty blights the lives of children and young people. Research has consistently shown that the most economically disadvantaged pupils across the United Kingdom (UK) have the poorest educational outcomes and that poverty has a pernicious effect on children’s well-being. However, far less is known about the ways that poverty is differentially experienced for children and young people in schools within the four jurisdictions of the UK. Are there historical, social and cultural factors that make poverty a postcode lottery in terms of quality of schooling in the different parts of the UK? Are successful local interventions context specific as the research evidence seems to suggest or can we learn from particular regions or cities? This introduction points out that anxieties about growing educational inequality in the UK have to be contextualised historically, geographically and in terms of the distinct political and socio-economic landscapes in England, Scotland, Wales and Northern Ireland.


The daily observations of smoke and sulphur dioxide that have been taken over the past ten years at some 1200 sites throughout the United Kingdom for the National Survey of Air Pollution, have provided a great deal of information on pollution in towns. An examination of this material is made to assess changes that have been occurring in levels of pollution in relation to the changing pattern of fuel consumption, and is used in trying to forecast the position in the next 15 or 20 years. A comparison is also made between pollution in towns in different parts of the U.K. The question of what levels of pollution may be tolerated is also considered. The part that aerodynamicists, architects and town planners can play in reducing urban pollution is discussed and an attempt is made to see what guidance can be given to them so that as far as pollution is concerned, the new and renewed towns of the future may avoid the mistakes of the past and therefore not need the costly remedial measures that now have to be taken in towns built in the past.

Social policies in the United Kingdom have undergone a ‘community turn’ over the last two decades, with emphasis increasingly on ‘community cohesion’ rather than ‘social disadvantage’ and exclusion. Whilst academics have explored this trend, there is less reflective work on academic community-based practice that operates on the same terrain. This chapter offers critical self-reflection of our academic practice within the community budgeting and commissioning phase in Balsall Heath, Birmingham. Reflecting on the processes of bringing different parts of the Balsall Heath community together for the project, we consider not just the challenges of ‘constructing community’ in this way, but also, the logics that underpin it.
