While improving the quality of seed potatoes can contribute to increasing its productivity, most farmers largely rely on the seed potatoes they save themselves. Seed potato system interventions need to address the quality of specially multiplied and farm-saved seed potatoes simultaneously. This book shows that positive selectionthe selection of healthy looking mother plants for the production of seed potatoes by aware potato farmerscan contribute to improving seed potato quality and the quality of the subsequent harvest.

DOWNLOAD EBOOK →Concentrating on the planning and design of cities, the three sections take a logical route through the discussion from the broad considerations at regional and city scale, to the larger city at high and lower densities through to design considerations on the smaller block scale. Key design issues such as access to facilities, access for sunlight, life cycle analyses, and the impact of communications on urban design are tackled, and in conclusion, the research is compared to large scale design examples that have been proposed and/or implemented over the past decade to give a vision for the future that might be achievable.

DOWNLOAD EBOOK →With the publication of Theory-Driven Evaluations, Huey-Tsyh Chen has given us an ambitious volume. . . . Indeed, it is the aspiration of this book to provide a conceptual framework that integrates the diverse approaches and paradigms of evaluation. For those of us accustomed to the rhetoric of the paradigm wars that have been raging in recent years, it is refreshing to find a text that works so assiduously at reconciliation. . . . There is much that is useful in Chen′s analysis. He gives us a full and thoughtful book that attempts no less than the construction of a conceptual framework for all of program evaluation. . . . It provides an impressive compendium of source material and references spanning not only evaluation, but related work in economics and public policy (this alone is worth the price of the book). . . . Chen′s Theory-Driven Evaluations provides a stimulating, even heroic attempt to bring some conceptual integration to a field that has been too long dominated by methodological paradigms and procedural particulars. --a prepublication review for Evaluation and Program Planning "Generous use of examples which are well selected and lucidly summarized." --Contemporary Sociology "Chen introduces a new, comprehensive framework for program evaluation that is designed to bridge the gap between method and theory-oriented perspectives. . . . For program planners, decision makers, scholars, and students, this volume clarifies, illuminates and provides unique insights into the conception, construction and implementation of a wide range of programs. . . . The research examples used in the discussion draw upon various areas, such as education, welfare, health, criminal justice, job training [and] family construction to attract a wider audience." --Journal of Applied Rehabilitation Counseling Program evaluation has traditionally emphasized the application of social science research methods in evaluation activities. However, there is a growing awareness that program theory is vital for broadening the scope and enhancing the usefulness of program evaluation. In Theory-Driven Evaluations, Huey-Tsyh Chen introduces a new, comprehensive framework for program evaluation that is designed to bridge the gap between the method- and theory-oriented perspectives. He provides an intensive discussion of the nature and functions of program theory, approaches to constructing program theories, and the integration of program theory with evaluation processes. Specific types of theory-driven evaluations, as well as principles and guidelines for application are developed for meeting different policy purposes. Application of systematic strategies is illustrated by concrete examples from a variety of evaluation studies in different fields. The presentation of this new perspective directly addresses the needs and concerns in both the professional and applied areas of program evaluation. For program planners, decisionmakers, scholars and students, this volume will clarify, illuminate, and provide unique insights into the conception, construction, and implementation of a wide range of programs.

DOWNLOAD EBOOK →This book provides basic knowledge on how to produce, multiply and use propagation material in seed potato production and supply systems world wide. Healthy, vigorous seed tubers are essential in potato production. Producing them used to be expensive and difficult. Multiplication rates in the field are low, seed-borne diseases are numerous and seed tubers lose quality during storage between growing seasons. Recently, novel methods of multiplication have revolutionised the seed potato industry. This has resulted in a diversity of seed production systems adjusted to the local potential and needs. This book summarises the current knowledge and assesses the efficient use of modern technology in different stages of seed production. It describes in detail what seed quality means, how (pre-)basic seed can be produced, how this can be multiplied, and how seed health is maintained. It also describes diverse examples of seed supply systems in different regions of the world. The book is aimed at agronomists, farm advisors, seed producers, breeders, and at those involved in seed policies, seed programme development and seed trade. Also recommended for (international) students in agronomy, horticulture and plant breeding.

Winans presents cutting-edge scholarship that covers the instrument's West African origins and its adaptations and circulation in the Caribbean and United States. The contributors provide detailed ethnographic and technical research on gourd lutes and ekonting in Africa and the banza in Haiti while also investigating tuning practices and regional playing styles. Other essays place the instrument within the context of slavery, tell the stories of black banjoists, and shed light on the banjo's introduction into the African- and Anglo-American folk milieus. Wide-ranging and illustrated with twenty color images, Banjo Roots and Branches offers a wealth of new information to scholars of African American and folk musics as well as the worldwide community of banjo aficionados.

Other factors include past incomes, individual incomes, household consumption, current unemployment, risk of unemployment, health status, education, and relative income in the area of residence. Paradoxically, when economists analyze a policy's impact on welfare they typically assume that people are the best judges of their own welfare, yet resist directly asking them if they are better off. Early ideas of utility were explicitly subjective, but modern economists generally ignore people's expressed views about their own welfare. Even using a broad set of conventional socioeconomic data may not reflect well people's subjective perceptions of their poverty. Ravallion and Lokshin examine the determinants of subjective economic welfare in Russia, including its relationship to conventional objective indicators. For data on subjective perceptions, they use survey responses in which respondents rate their level of welfare from poor to rich on a nine-point ladder. As an objective indicator of economic welfare, they use the most common poverty indicator in Russia today, in which household incomes are deflated by household-specific poverty lines. They find that Russian adults with higher family income per equivalent adult are less likely to place themselves on the lowest rungs of the subjective ladder and more likely to put themselves on the upper rungs. But current household income does not explain well self-reported assessments of whether someone is poor or rich. Expanding the set of variables to include incomes at different dates, expenditures, educational attainment, health status, employment, and average income in the area of residence doubles explanatory power. Healthier and better educated adults with jobs perceive themselves to be better off, controlling for income. The unemployed view their welfare as lower, even with full income replacement. Individual income matters independent of per capita household income. Relative income also matters. Living in a richer area lowers perceived economic welfare, controlling for income and other factors. This paper-a product of Poverty and Human Resources, Development Research Group-is part of a larger effort in the group to better understand the relationship between objective and subjective economic welfare.
