Many governments in developing countries are making efforts to support the development of micro- and small enterprises (MSEs), as they recognise their important role in employment creation and poverty reduction. However, millions of people who work in MSEs are paid low incomes, have little or no social protection and are exposed to dangerous working conditions. This paradox stems from a policy and regulatory environment that should help the development of MSEs and improve the quality of jobs provided by them, but in practice often establishes biases and stifles growth. Based on studies carried out in Chile, Guinea, Pakistan, Peru, South Africa, Tanzania and Vietnam, this book looks beyond MSE promotion initiatives to analyse the overall policy and regulatory environment. It examines the impact of national business laws and taxation, labour regulations, trade and finance policies; identifies common problems and presents major principles for reform. More than simply helping to create more jobs, this approach aims to help to create more jobs of better quality.
The volume describes physical properties of tungsten metal and covers specifically surface properties, electron emission, and field evaporation. Tungsten surfaces are probably the most extensively studied metal surfaces. Recently, experimentalists and theorists have focussed their interest on the atomic structure, lattice dynamics, and electronic properties of the W(100) surface. While the structure of the reconstructed low-temperature surface is well established, there are still unresolved problems concerning the structure at and above room temperature, the nature of the phase transition, and the driving force for the reconstruction. There are numerous and partly conflicting data on the surface energy, the self-diffusion parameters, and the work function of single-crystal and polycrystal tungsten surfaces. Electron emission, which is of fundamental importance for many applications, comprises thermionic, field, photofield, and photoelectric emission as well as emission induced by impinging electrons, atoms, or ions. Pioneering work in areas like thermionic or field emission is comprehensively discussed. Very recent studies of valence-band and core-level spectra moreover provide detailed information on intrinsic surface properties.
Traditional Chinese medicine has been used for thousands of years by a large population. It is currently still serving many of the health needs of the Chinese people; and still enjoying their confi dence it is practised in China in parallel with modern Western medical treatment. In addition to scientific organisations dedi cated to modern Western medicine, e. g. the Chinese Academy of Medical Sciences and various medical schools, a series of parallel institutions have been established in China to promote traditional Chinese medicine, such as the Academy of Traditional Chinese Medicine and training institutions. Almost all hospitals in China have a department of traditional medicine. Furthermore, a large number of scientific journals are dedicated to traditional Chinese medicine, covering both experimental and clinical investigations. Medicinal materials constitute a key topic in the treatment of disease according to traditional Chinese medicine. The Chinese Pharmacopoeia (1985 edition) is therefore divided into two sepa rate volumes, Volume I containing traditional Chinese medicinal materials and preparations and Volume II containing pharmaceu tics of Western medicine. The oldest Chinese review of medicinal materials, Shennong Bencao Jing (100-200 A. D. ), covered 365 herbal drugs. The clas sic compilation in this field, Bencao Gangmu (Compendium of Materia Medica), was published in 1578 by Li Shi-zhen and recorded as many as 1898 crude drugs of plant, animal and min eral origin.
The transplantation of African musical cultures to the Americas was a multi-track and multi-time process. In the past many historical studies of African diaspora music, dance and other aspects of expressive culture concentrated on events in the Americas. What happened before the American trauma and simultaneously in Africa was often looked at unhistorically. In this book, world-renowned ethnomusicologist Gerhard Kubik considers African music and dance forms as the products of people living in various African cultures which have changed continuously in history, absorbing and processing elements from inside and outside the continent, creating new styles and fashions all the time. African diaspora music then appears as a consequent and creative extension overseas of African musical cultures that have existed in the period between the sixteenth and the twentieth century. From this perspective African diaspora music cannot be described adequately in terms of "retentions" and "survivals," as if African cultures in the Americas were doomed from the outset and perhaps only by some act of mercy permitted to "retain" certain elements. Using field research and documentary sources, Kubik tracks down some aspects of the Angolan dimension in the panorama of African music and dance cultures in Brazil, and also addresses methodology applicable in the wider context of African diaspora cultural studies.
Most vertebrate cranial sense organs arise from placodes. These placodes give rise to sensory neurons that transmit information to the brain and neurosecretory cells. This book reviews the evolutionary origin of the sensory and neurosecretory cell types. It summarizes our current understanding of vertebrate evolution, clarifies conceptual issues relating to homology and evolutionary innovation of cell types, compares the sensory and neurosecretory cell types with similar cell types in other animals, and addresses the question of how cranial placodes evolved as novel structures in vertebrates by redeploying pre-existing and sometimes evolutionarily ancient cell types.
Globalisation affects the enterprises and workers of nearly all countries, in goods as well as services sectors. This book is part of a series of seven country studies on the soical impact of globalisation. This study outlines some recent trends in globalisation and social progress, assesses the social effects and examines a variety of policy issued, including international integration, changing labour market conditions, protection against labour and social insecurities, and labour management relations.
