Books on the topic 'Mixed scheme'

The goal of Chapter 2 is to derive the properties of common processes and, based on these properties, to develop a general scheme for classifying processes. Stationary processes includes white noise, moving average (MA), and autoregressive (AR) processes. MA and AR models can approximate mixed ARMA models. A lag or backshift operator is used to solve ARIMA models for time series observations or random shocks. Covariance functions are derived for each of the common processes.Maximum likelihood estimates are introduced for the purposes of estimating autoregressive and moving average parameters.

This book presents an important breakthrough in arithmetic geometry. In 2014, this book's author delivered a series of lectures at the University of California, Berkeley, on new ideas in the theory of p-adic geometry. Building on his discovery of perfectoid spaces, the author introduced the concept of “diamonds,” which are to perfectoid spaces what algebraic spaces are to schemes. The introduction of diamonds, along with the development of a mixed-characteristic shtuka, set the stage for a critical advance in the discipline. This book shows that the moduli space of mixed-characteristic shtukas is a diamond, raising the possibility of using the cohomology of such spaces to attack the Langlands conjectures for a reductive group over a p-adic field. The book follows the informal style of the original Berkeley lectures, with one chapter per lecture. It explores p-adic and perfectoid spaces before laying out the newer theory of shtukas and their moduli spaces. Points of contact with other threads of the subject, including p-divisible groups, p-adic Hodge theory, and Rapoport-Zink spaces, are thoroughly explained.

With this book, Rachel Afi Quinn makes the case for a transnational feminist cultural studies lens of analysis and an ethnographic approach to the study of race, gender, and visual culture in the Dominican Republic. This book provides a new window into contemporary life in Santo Domingo through which surrealist cultural productions reflect the social climate. Quinn theorizes the ways that the racial meaning of Dominican women’s mixed-race bodies “see/saw” in the viewing moment, as they are read visually in relation to others and informed by particular narratives of identity. Drawing on some forty interviews conducted by the author, this text centers these voices as it reveals the ways that the mixed-race bodies of Dominican women and girls signify within a racial schema tied to an economy in which they are commodified. Queer identities and fluid sexualities intersect with racial ambiguity and Dominican whiteness, Quinn argues, while incorporating public art, digital images, and Dominican film and music videos that are circulated transnationally, including performances by Rita Indiana Hernández and Michelle Rodriguez. Numerous other works by Dominican women artists and activists including print and online publications, documented live performances, photographic images, and social media discourse compose this text. Transnational political organizing is also considered here as part of a legacy of Dominican feminist activism against patriarchal oppression

This chapter examines the spread of standards and certification in green industries including IFOAM in organic food, ECOCERT in beauty, BREEAM and LEED in building, and Green Globe in tourism. These were the work of a set of institutional entrepreneurs who argued that standards and certification were the path to credibility but the evidence on impact is mixed. Conflicting or confusing certification schemes, as in beauty, were a problem for the growth of an industry. However, standards and certification often needed to be set at such a level that they were seen as being in reach of most participants. As a result there was some tendency for a race to the bottom. Standards and certification also resulted in misaligned incentives and the potential for gaming. Above all, certification shed light on the contested meaning of sustainability.

This book examines the racialization of Blasians – mixed race people with Black and Asian ancestry – that neither sees them as new or unique, nor as a racial salve to move the United States past the problem of the colour line. The emergence of Blasian celebrities and the analyses of these stars acknowledges that to understand what and who is a Blasian means to first understand hegemonic notions of both Blacks and Asian/Americans. Contextualized against those dominant discourses Blasians explode the narrow boundaries of authenticity around racialized categories. Multiracial people are just as capable as monoracial people of upholding hierarchies of identity, as well as dismantling those hierarchies. Thus, in this book Blasians do not escape race, or erase race, but they do deconstruct normative instantiations of identity. The presence, mobility, and utility of these multiracial celebrities within both U.S. and global racial schemas simultaneously realize and complicate potential alternatives to racial and racist paradigms. These mixed race stars draw attention to how risible and absurd the biological and cultural premises for racialization truly are, and demonstrate potential alternatives for affiliation that do not rely on genetic material.

A substantial amount of development programming assumes that women have preferences or aptitudes that are more conducive to economic development. For example, conditional cash transfer programmes commonly deliver funding to female household heads, and many microcredit schemes focus on women’s savings groups. This chapter examines a public goods game in northern Liberia. Women contributed substantially more to a small-scale development project when playing with other women than in mixed-gender groups, where they contributed at about the same levels as men. We try to explain this composition effect using a structural model, survey responses, and a second manipulation. Results suggest women in the all-women group put more weight on co-operation regardless of the value of the public good, the fear of discovery, or the desire to match others’ behaviour. We conjecture that players have stronger motivation to signal public-spiritedness when primed to consider themselves representatives of the women of the community.

This book provides a theoretically informed, empirically rich account of the development, causes and consequences of public housing (council/local authority/social) estate regeneration within the context of London’s housing crisis and widening social inequality. It focuses on regeneration schemes involving comprehensive redevelopment – the demolition of council estates and their rebuilding as mixed-tenure neighbourhoods with large numbers of market properties which fuels socio-spatial inequalities via state-led gentrification. The book deploys an interdisciplinary perspective drawn from sociology, geography, urban policy and housing studies. By foregrounding estate residents’ lived experiences – mainly working-class tenants but also working- and middle-class homeowners – it highlights their multiple discontents with the seemingly never-ending regeneration process. As such, the book critiques the imbalances and silences within the official policy discourse in which there are only regeneration winners while the losers are airbrushed out of history. The book contains many illustrations and is based on over a decade of research undertaken at several London council-built estates. The book is divided into three parts. Part One (Chapters 2-4) examines housing policy and urban policy in relation to the expansion and contraction of public housing in London, and the development of estate regeneration. Part Two (Chapters 5-7) analyses residents’ experiences of living at London estates before regeneration begins. It argues that residents positively valued their homes and neighbourhoods, even though such valuation was neither unqualified nor universal. Part Three (Chapters 8-12) examines residents’ experiences of living through regeneration, and argues that comprehensive redevelopment results in degeneration, displacement, and fragmented rather than mixed communities.

Abstract German publishers transformed the political culture of central Europe. Their presses, bookshops, and commercial networks promoted oppositional politics, especially those of liberalism and democratic radicalism. Adapting a centuries-long legacy of marketing forbidden literature to the modern era, the book trade vigorously contested the censorship regimes of Prussia and Austria with an array of legal and illegal tricks. Driven by profit and political conviction, publishers became cultural brokers and political actors, and their achievements are many. Alongside the smuggling of banned books, they promoted a broad spectrum of legal dissent—from highbrow journals to middlebrow lexica to flyers. They circulated Western political ideas through extensive translation, devised new formats to widen the reception of commentary, and designed marketing schemes to broaden the reading nation. But the aspiration of popularizing political dissent had mixed results. If the book trade established liberalism as an inexorable political force, democratic radicalism never achieved mainstream status. Between the Carlsbad Decrees of 1819 and the Imperial Press Law of 1874, governments criminalized republicanism and other democratic doctrines, denying them necessary access to broader audiences. Recounting the triumphs and setbacks of marketing political dissent, James Brophy’s study brings alive the turbulent world of publishing. This sweeping narrative redefines the political public sphere in nineteenth-century central Europe.

Explores the prominent role of Highland Scots in the exploitation of enslaved Africans and their descendants in the cotton, sugar and coffee plantations of the 18th and 19th centuries. Pays special attention to the new colonies of the southern Caribbean, including Grenada and Guyana, and to Suriname in the years to 1863 Contributes to the debate on reparation by reappraising the idea of Scots complicity in the slave trade Includes a short foreword by Rod Westmaas and Juanita Cox-Westmaas, co-founders of Guyana Speaks, an organisation for the Guyanese diaspora in London Scots were involved in every stage of the slave trade: from captaining slaving ships to auctioning captured Africans in the colonies and hunting down those who escaped from bondage. This book focuses on the Scottish Highlanders who engaged in or benefitted from these crimes against humanity in the Caribbean Islands and Guyana, some reluctantly but many with enthusiasm and without remorse. Their voices are clearly heard in the archives, while in the same sources their victims’ stories are silenced – reduced to numbers and listed as property. David Alston gives voice not only to these Scots but to enslaved Africans and their descendants – to those who reclaimed their freedom, to free women of colour, to the Black Caribs of St Vincent, to house servants, and to children of mixed race who found themselves in the increasingly racist society of Britain in the mid-1800s. As Scots recover and grapple with their past, this vital history lays bare the enormous wealth generated in the Highlands by slavery and emancipation compensation schemes. This legacy, entwined with so many of our contemporary institutions, must be reckoned with.

Hard coal mining is characterised by features that pose numerous challenges to its current operations and cause strategic and operational problems in planning its development. The most important of these include the high capital intensity of mining investment projects and the dynamically changing environment in which the sector operates, while the long-term role of the sector is dependent on factors originating at both national and international level. At the same time, the conditions for coal mining are deteriorating, the resources more readily available in active mines are being exhausted, mining depths are increasing, temperature levels in pits are rising, transport routes for staff and materials are getting longer, effective working time is decreasing, natural hazards are increasing, and seams with an increasing content of waste rock are being mined. The mining industry is currently in a very difficult situation, both in technical (mining) and economic terms. It cannot be ignored, however, that the difficult financial situation of Polish mining companies is largely exacerbated by their high operating costs. The cost of obtaining coal and its price are two key elements that determine the level of efficiency of Polish mines. This situation could be improved by streamlining the planning processes. This would involve striving for production planning that is as predictable as possible and, on the other hand, economically efficient. In this respect, it is helpful to plan the production from operating longwalls with full awareness of the complexity of geological and mining conditions and the resulting economic consequences. The constraints on increasing the efficiency of the mining process are due to the technical potential of the mining process, organisational factors and, above all, geological and mining conditions. The main objective of the monograph is to identify relations between geological and mining parameters and the level of longwall mining costs, and their daily output. In view of the above, it was assumed that it was possible to present the relationship between the costs of longwall mining and the daily coal output from a longwall as a function of onerous geological and mining factors. The monograph presents two models of onerous geological and mining conditions, including natural hazards, deposit (seam) parameters, mining (technical) parameters and environmental factors. The models were used to calculate two onerousness indicators, Wue and WUt, which synthetically define the level of impact of onerous geological and mining conditions on the mining process in relation to: —— operating costs at longwall faces – indicator WUe, —— daily longwall mining output – indicator WUt. In the next research step, the analysis of direct relationships of selected geological and mining factors with longwall costs and the mining output level was conducted. For this purpose, two statistical models were built for the following dependent variables: unit operating cost (Model 1) and daily longwall mining output (Model 2). The models served two additional sub-objectives: interpretation of the influence of independent variables on dependent variables and point forecasting. The models were also used for forecasting purposes. Statistical models were built on the basis of historical production results of selected seven Polish mines. On the basis of variability of geological and mining conditions at 120 longwalls, the influence of individual parameters on longwall mining between 2010 and 2019 was determined. The identified relationships made it possible to formulate numerical forecast of unit production cost and daily longwall mining output in relation to the level of expected onerousness. The projection period was assumed to be 2020–2030. On this basis, an opinion was formulated on the forecast of the expected unit production costs and the output of the 259 longwalls planned to be mined at these mines. A procedure scheme was developed using the following methods: 1) Analytic Hierarchy Process (AHP) – mathematical multi-criteria decision-making method, 2) comparative multivariate analysis, 3) regression analysis, 4) Monte Carlo simulation. The utilitarian purpose of the monograph is to provide the research community with the concept of building models that can be used to solve real decision-making problems during longwall planning in hard coal mines. The layout of the monograph, consisting of an introduction, eight main sections and a conclusion, follows the objectives set out above. Section One presents the methodology used to assess the impact of onerous geological and mining conditions on the mining process. Multi-Criteria Decision Analysis (MCDA) is reviewed and basic definitions used in the following part of the paper are introduced. The section includes a description of AHP which was used in the presented analysis. Individual factors resulting from natural hazards, from the geological structure of the deposit (seam), from limitations caused by technical requirements, from the impact of mining on the environment, which affect the mining process, are described exhaustively in Section Two. Sections Three and Four present the construction of two hierarchical models of geological and mining conditions onerousness: the first in the context of extraction costs and the second in relation to daily longwall mining. The procedure for valuing the importance of their components by a group of experts (pairwise comparison of criteria and sub-criteria on the basis of Saaty’s 9-point comparison scale) is presented. The AHP method is very sensitive to even small changes in the value of the comparison matrix. In order to determine the stability of the valuation of both onerousness models, a sensitivity analysis was carried out, which is described in detail in Section Five. Section Six is devoted to the issue of constructing aggregate indices, WUe and WUt, which synthetically measure the impact of onerous geological and mining conditions on the mining process in individual longwalls and allow for a linear ordering of longwalls according to increasing levels of onerousness. Section Seven opens the research part of the work, which analyses the results of the developed models and indicators in individual mines. A detailed analysis is presented of the assessment of the impact of onerous mining conditions on mining costs in selected seams of the analysed mines, and in the case of the impact of onerous mining on daily longwall mining output, the variability of this process in individual fields (lots) of the mines is characterised. Section Eight presents the regression equations for the dependence of the costs and level of extraction on the aggregated onerousness indicators, WUe and WUt. The regression models f(KJC_N) and f(W) developed in this way are used to forecast the unit mining costs and daily output of the designed longwalls in the context of diversified geological and mining conditions. The use of regression models is of great practical importance. It makes it possible to approximate unit costs and daily output for newly designed longwall workings. The use of this knowledge may significantly improve the quality of planning processes and the effectiveness of the mining process.
