As one of the early graduate students of the Penn State Biomechanics Laboratory (1970–1974), I had the pleasure of being involved in the lab developed under the direction of Dr. Richard Nelson. His vision of applying engineering principles to human movement, particularly through the vehicle of sport analysis, inspired many to commit to a career of biomechanical exploration of the many aspects of human movement. By bringing many international scholars to the lab, he exposed his students to innovative and unique approaches to research. By developing technical applications, he made biomechanical inquiry more scientific and applicable. By caring for and mentoring a new generation of scientists and providing them the direction and tools they would need to establish their own labs and careers, he helped us become teachers, researchers, consultants, and mentors for a new generation of students. His love of life inspired us all to further the groundbreaking work he had begun and continued throughout his amazing career. His contributions to the field of biomechanics through his visionary establishment of societies, journals, collegial relationships, and consulting skills have served our community well. It was an honor and a privilege to know and learn from him.

The spatial information regarding the use of territory is one of the many strategies used to answer and to inform about what happened, what is happening and what may happen in geographic space. Therefore, the mapping of land use as a communication tool for the spatial data made significant progress in improving sources of information, especially over the last few decades, with new generation remote sensing products for data manipulation.

After Utopia was the author's first book, a harbinger of her renowned career in political philosophy. Throughout the many changes in political thought during the last half century, this important work has withstood the test of time. The book explores the decline of political philosophy, from Enlightenment optimism to modern cultural despair, and offers a critical, creative analysis of this downward trend. It looks at Romantic and Christian social thought, and shows that while the present political fatalism may be unavoidable, the prophets of despair have failed to explain the world they so dislike, leaving the possibility of a new and vigorous political philosophy. With a foreword examining the book's continued relevance, this current edition introduces a remarkable synthesis of ideas to a new generation of readers.

It almost seems a sort of impertinence to add yet another layer to the many records (recently estimated as numbering some 230,000 books) of Roman experiences and impressions. Can there possibly be any vision of the Eternal City, any reaction to its manifold variety and continuity, which has not already been set down, romantically or painstakingly according to the writer's ability? Yet it may be that each new generation, even each new visitor, enjoys a private and different view of Rome, and experiences something unfelt by the multitudes of previous explorers. To attempt to translate that vision, to reduce it to words for others to share, is a sure recipe for another attack of nostalgia; and who would wish to escape that?

Pipelines are an integral part of the world's economy and literally billions of pounds worth of fluids are moved each year in pipelines of varying lengths and diameters. As the cost of some of these fluids and the price of moving them has increased, so the need to measure the flows more accurately and control and operate the line more effectively has arisen. Instrumentation and control equipment has developed steadily in the past decade but not as fast as the computers and microprocessors that are now a part of most large scale pipeline systems. It is the interfacing of the new generation of digital and sometimes ‘intelligent’ instrumentation with smaller and more powerful computers that has led to a quiet but rapid revolution in pipeline monitoring and control. This paper looks at the more significant developments from the many that have appeared in the past few years and attempts to project future trends in the industry for the next decade.

This note is intended primarily for graduate students and other researchers without previous field experience in studying international organizations. I do not propose either to summarize or to repeat the many expositions on survey research, interviewing, and the like; radier the focus here will be primarily on a number of the “nuts and bolts” problems not usually treated in the literature that the researcher is likely to face. If the individual is aware of these beforehand he can save himself time and a few mistakes.

This mixed questionnaire survey sought to determine if lecturers who learned to speak and understand Nigerian Creole before English are willing to use the language as medium of instruction. The respondents were comprised of 560 lecturers and graduate students (i.e. master’s, doctoral) selected through a purposeful random sampling frame from 15 public institutions of higher learning in Nigeria. Lecturers declined to use Nigerian Creole as medium of instruction because they feared that its use might negatively affect their students’ learning of English. Graduate students indicated willingness to receive instruction through a combination of English and Nigerian Creole because they perceived the use of Nigerian Creole as fun and representative of the voice of a new generation of Nigerians. The sample reported that prior knowledge of Nigerian Creole does not facilitate the learning of English because both languages are too different to facilitate a transfer of learning.

This accessible text provides a concise but comprehensive introduction to the biology of global grasslands. Grasslands are vast in their extent, with native and non-native grasslands now covering approximately 50 percent of the global terrestrial environment. They are also of vital importance to humans, providing essential ecosystem services and some of the most important areas for the production of food and fibre worldwide. It has been estimated that 60 percent of calories consumed by humans originate from grasses, and most grain consumed is produced in areas that were formerly grasslands or wetlands. Grasslands are also important because they are used to raise forage for livestock, represent a source of biofuels, sequester vast amounts of carbon, provide urban green-space, and hold vast amounts of biodiversity. Intact grasslands contain an incredibly fascinating set of plants, animals, and microbes that have interested several generations of biologists, generating pivotal studies to important theoretical questions in ecology. As with other titles in the Biology of Habitats Series, the emphasis is on the organisms that dominate this environment although restoration, conservation, and experimental aspects are also considered. The Biology of Grasslands is suitable for both senior undergraduate and graduate students (in departments of biology, geography, and environmental science) taking courses in grassland ecology, plant ecology, and rangeland ecology as well as the many professional ecologists and conservation biologists requiring an authoritative overview of the topic.

Caves and other subterranean habitats with their often strange (even bizarre) inhabitants have long been objects of fascination, curiosity, and debate. The question of how such organisms have evolved, and the relative roles of natural selection and genetic drift, has engaged subterranean biologists for decades. Indeed, these studies continue to inform the general theory of adaptation and evolution. Subterranean ecosystems generally exhibit little or no primary productivity and, as extreme ecosystems, provide general insights into ecosystem function. The Biology of Caves and other Subterranean Habitats offers a concise but comprehensive introduction to cave ecology and evolution. Whilst there is an emphasis on biological processes occurring in these unique environments, conservation and management aspects are also considered. The monograph includes a global range of examples from more than 25 countries, and case studies from both caves and non-cave subterranean habitats; it also provides a clear explanation of specialized terms used by speleologists. This accessible text will appeal to researchers new to the field and to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview. Its engaging style will also make it suitable for undergraduate and graduate students taking courses in cave and subterranean biology. Its more than 650 references, 150 of which are new since the first edition, provide many entry points to the research literature.

In this talk, the development of key elements for BioPOEMS (Biomedical Polymer-based Opto Electro Mechanical Systems) will be discussed as a new generation of microscopic and microanalysis biochips. Current BioMEMS (Biomedical Microelectromechanical Systems) technology is in its infancy stage. Just as silicon-based microelectronics technology went through many stages since the late ‘60's, BioMEMS technology will have to overcome many obstacles before becoming a mature industry. The IC industry was made possible by the development of fabrication processes, integration technologies, and design tools. Similarly, the field of BioMEMS must prepare new components with biomaterials and tools for the development of new microsystems, enabling the combination of biological sensors and actuators with the rapidly growing capabilities of bioinformatics.Polymers are not only used in macroscopic systems, but are now increasingly finding use in the microscopic realm such as microfluidic devices. Among the many different classes of polymers, it is the fluoropolymers that provide the most unique material characteristics.

The spectacular decline of the expatriate business houses of eastern India in this century is one of the many underdeveloped areas of Indian economic history. The extent of the decline itself seems hard to exaggerate. In 1900 almost all the commanding heights of the colonial economy appeared to the dominated by expatriate and foreign firms, most of them British. Not only was the foreign trade of Bengal almost exclusively in their hands, but so was the industrial and banking structure. In addition, most historians of the period have stressed that the expatriate sector was able to dominate internal trade, operating in amonopsony position in regard to cash crop production and marketing and also, thanks to its contacts with government, the railways and the port trusts, to enjoy hegemonic powers that impeded the development of indigenous rivals. Thus, as A. K. Bagchi has stressed, 'social discrimination was complemented and supported by political, economic, administrative and financial arrangements which afforded European businessmen a substantial and systematic advantage over their Indian rivals in India.' The fate of the expatriate groups since 1950 has beenvery different. Many suffered considerable depredations during and after the second world war, losing important sectors of their business to Indian rivals, and even being bought out entirely by native enter-prise. Such expatriate interests as survived after Independence have generally failed to perform well. Their recent history has been agloomy one of a steady erosion of profitability and viability, so that most of those that still remain are now taken seriously only by a new generation of indigenous speculators and asset strippers.
