Negro Employment in Land and Air Transport
Herbert R. Northrup; Howard W. Risher Jr.; Richard D. Leone; Philip W. Jeffress
University of Pennsylvania Press
1971
sidottu
The authors examine both past and current practices and policies influencing black employment in the railroad, airline, trucking, and urban transit industries. Technological unemployment, declining traffic, and discrimination by unions, carriers, and government agencies have reduced both the number and proportion of blacks in the railroad industry, which was once one of the nation's leading employers of blacks. These, same railroading mores have affected black employment in airlines and urban transit in the past but today other forces are working to improve black representation in the former and leading to a heavily black work force in the latter. In the trucking industry, the Teamsters' Union and government policy are keys to Negro employment, with the union dragging its feet in supporting an increased number of black over-the-road drivers. A final section compares the situations in the four industries and forecasts future Negro employment trends in light of the most recent employment data, occupational needs, governmental policy, and other significant factors.

In September 2011, AEI honored longtime AEI colleague Walter Berns with a panel dedicated to discussing his scholarship on the Constitution and the republican polity it supports. At this event, former AEI President Arthur C. Brooks announced that henceforth, AEI's annual Constitution Day celebration would be named in honor of Walter. This volume is a collection of the 13 Walter Berns Constitution Day Lectures given since 2012. Walter's own work ranged widely, addressing issues on such diverse topics as civil and religious liberties, free speech, capital punishment, political philosophy, political science, presidential selection, and patriotism. It's fitting that the lectures named after him cover an equally broad array of topics related to the Constitution and the American republic.

This collection features six peer-reviewed reviews on the economics of key agricultural practices.The first chapter assesses the economic impact of horticultural crops and integrated pest management programmes. The chapter highlights the importance of considering agricultural system design and the utilisation of novel control tactics.The second chapter considers the economic consequences of novel integrated weed management (IWM) strategies, as well as the different approaches used to assess the economics of IWM strategies.The third chapter reviews developments in methods to assess the economic value of agricultural biodiversity. The chapter also outlines the limitations of these methods and proposes a possible, novel way forward.The fourth chapter provides an overview of the economic barriers faced by smallholder farmers, including land, labour, capital and inputs, and their impact on farm profitability.The fifth chapter reviews the economics of soil health, focussing on the adoption of soil health management practices by farmers and the effectiveness of incentives.The final chapter examines the use of economic research as a tool to determine the profitability and adoption potential for a number of precision agriculture technologies.
Grammar-Based Feature Generation for Time-Series Prediction
Anthony Mihirana De Silva; Philip H. W. Leong
Springer Verlag, Singapore
2015
nidottu
This book proposes a novel approach for time-series prediction using machine learning techniques with automatic feature generation. Application of machine learning techniques to predict time-series continues to attract considerable attention due to the difficulty of the prediction problems compounded by the non-linear and non-stationary nature of the real world time-series. The performance of machine learning techniques, among other things, depends on suitable engineering of features. This book proposes a systematic way for generating suitable features using context-free grammar. A number of feature selection criteria are investigated and a hybrid feature generation and selection algorithm using grammatical evolution is proposed. The book contains graphical illustrations to explain the feature generation process. The proposed approaches are demonstrated by predicting the closing price of major stock market indices, peak electricity load and net hourly foreign exchange client trade volume. The proposed method can be applied to a wide range of machine learning architectures and applications to represent complex feature dependencies explicitly when machine learning cannot achieve this by itself. Industrial applications can use the proposed technique to improve their predictions.

Przed opracowaniem nowoczesnych metodologii, technik i sprzętu wielu pracownik w musialo polegac na prostszych metodach badawczych, aby rozwiązac ogromne problemy, przed kt rymi stoją zar wno rolnicy, przemysl, jak i poszczeg lni chlopi. W niniejszej książce podjęto pr bę wprowadzenia do książki pilnych problem w polowych, kt re przez wiele lat szczeg lnie spustoszyly pola trzciny cukrowej na świecie, ze szczeg lnym uwzględnieniem doświadczeń sudańskich, począwszy od lat 60-tych XX wieku. Smutna choroba trzciny cukrowej wywolana przez grzyb Basidiomycete pojawila się w Sudanie w sezonie zbior w 1964/65 wraz z powstaniem pierwszej cukrowni w Guneid. Dlatego też badanie to zbiega się w czasie i oznacza 47 lat dewastacji upraw trzciny cukrowej przez tę pojedynczą chorobę, kt ra spowodowala ogromne, nie odnotowane straty fizyczne i w sensie pieniężnym, szczeg lnie w suchych, p lpustynnych warunkach Sudanu, kt re sprzyjają tej chorobie. Wcześniejsza epifitotyka doprowadzila do wycofania z produkcji popularnych odmian wysokoplennych.

This book proceeds from a meeting at the Santa Fe Institute where economists and physical and biological scientists came together to discuss a conceptual framework incorporating a more appropriate mathematics with a greatly strengthened capacity to deal simultaneously with multiple variables, nonlinearity, incomplete information and dynamical processes.
Basic Notions of Condensed Matter Physics is a clear introduction to some of the most significant concepts in the physics of condensed matter. The general principles of many-body physics and perturbation theory are emphasised, providing supportive mathematical structure. This is an expansion and restatement of the second half of Nobel Laureate Philip Anderson's classic Concepts in Solids.
One day in 1938, John Dewey addressed a room of professional educators and urged them to take up the task of “finding out just what education is.” Reading this lecture in the late 1940s, Philip W. Jackson took Dewey’s charge to heart and spent the next sixty years contemplating his words. The stimulating result of a lifetime of thinking about educating, What Is Education? is a profound philosophical exploration of how we transmit knowledge in human society and how we think about accomplishing that vital task. Most contemporary approaches to education follow a strictly empirical track, aiming to discover pragmatic solutions for teachers and school administrators. Jackson argues that we need to learn not just how to improve on current practices but also how to think about what education means—in short, we need to answer Dewey by constantly rethinking education from the ground up. Guiding us through the many facets of Dewey’s comments, Jackson also calls on Hegel, Kant, and Paul Tillich to shed light on how a society does, can, and should transmit truth and knowledge to successive generations. Teasing out the implications in these thinkers’ works ultimately leads Jackson to the conclusion that education is at root a moral enterprise. At a time when schools increasingly serve as a battleground for ideological contests, What Is Education? is a stirring call to refocus our minds on what is for Jackson the fundamental goal of education: making students as well as teachers—and therefore everyone—better people.

Tanga Region, Tanzania, is an area of persistent rural poverty with a long history of drought, floods, food shortages, famine, and social and economic disruption. Though farmers have been cultivating the land there for hundreds of years, they have consistently been unable to supply adequate food for the region's inhabitants. In "Challenging Nature", Philip Porter examines eighteen farming communities to understand what the farmers there know about their environment and which historical and economic factors play into the lack of food security. Porter first began work on this project in 1972, asking 250 farmers in the region about life history, environmental and agricultural changes, types of crops grown and methods of planting, environmental assessments, agricultural practices, food and water supplies, training and education, and attitudes toward nature. Twenty years later, he returned and reinterviewed as many farmers as could be found from the first survey. The result contextualizes the environmental history of the region while informing current and future agricultural development.
Since recording its first AIDS cases in 1983, Tanzania has reported nearly 90,000 more to the World Health Organization - more than any other country in Africa. The AIDS epidemic has forced Africans to reflect upon the meaning of traditional ideas and practices related to sexuality and fertility, and upon modernity and biomedicine. In this book, anthropologist Philip Setel observes Tanzania's Chagga people and their attempts to cope with and understand AIDS. The work presents an extended case study of the 20th-century AIDS epidemic and the cultural circumstances from which it emerged. It brings together anthropology, demography and epidemiology to explain how a particular community in Africa experiences AIDS.
