One Rock, Two Principles


Book Description

This case study, intended for an introductory international relations course, is designed to help students understand the choices states must make between acting on their ideals (as suggested by the liberal idealist school) and acting in their self-interests (the realist school). It focuses on an issue that British Secretary of State Jack Straw considered in November 2002: whether to alter the status of Gibraltar, which had been a British colony for nearly three centuries. Straw's decision was unlikely to dramatically affect Great Britain's fate or even significantly alter its security, given that the peninsula's area is just 6.25 square miles, and its population was about 30,000. Nonetheless, the issue pitted two basic principles of British foreign policy against each other. The realist tradition suggested Britain ought to cede at least partial control over Gibraltar to Spain. On the other hand, British liberal tradition argued for allowing the Gibraltarians' self-determination, which would lead either to independence or to continued British sovereignty.




Principles of Rock Deformation


Book Description

Physicists attempt to reduce natural phenomena to their essential dimensions by means of simplification and approximation and to account for them by defining natural laws. Paradoxically, whilst there is a critical need in geology to reduce the overwhelming field information to its essentials, it often re mains in an over-descriptive state. This prudent attitude of geologists is dictated by the nature of the subjects being consi dered, as it is often difficult to derive the significant parame ters from the raw data. It also follows from the way that geolo gical work is carried out. Geologists proceed, as in a police investigation, by trying to reconstruct past conditions and events from an analysis of the features preserved in rocks. In physics all knowledge is based on experiment but in the Earth Sciences experimental evidence is of very limited scope and is difficult to interpret. The geologist's cautious approach in accepting evidence gained by modelling and quantification is sometimes questionable when it is taken too far. It shuts out potentially fruitful lines of advance; for instance when refu sing order of magnitude calculations, it risks being drowned in anthropomorphic speculation. Happily nowadays, many more studies tend to separate and order the significant facts and are carried out with numerical constraints, which although they are approxi mate in nature, limit the range of hypotheses and thus give rise to new models.




The Physical Principles of Rock Magnetism


Book Description

Developments in Solid Earth Geophysics 5: The Physical Principles of Rock Magnetism explores the physical principles of rock magnetism, with emphasis on the properties of finely divided magnetic materials. It discusses the origin and stability of rock magnetizations, the role of remanent magnetism in interpreting magnetic surveys, magnetic anisotropy as an indicator of rock fabric, and the relationship between piezomagnetic changes and seismic activity. Organized into 13 chapters, this volume discusses the properties of solids, magnetite and hematite grains, and rocks with magnetite grains. It also explains various theories and equations in studying rock magnetism. Different types of magnetization are discussed, including their occurrence, significance, and effects. Some of the types include depositional and chemical remanent and thermoremanent magnetization. In addition, this book explains the thermal activation and Piezomagnetic effects, as well as the reversals of remanent magnetism. This reference contains appendices with tables of relevant functions, such as Langevin Function. This book is a valuable source of information for physicists and geologists.

Social Science Research


Book Description

This book is designed to introduce doctoral and graduate students to the process of conducting scientific research in the social sciences, business, education, public health, and related disciplines. It is a one-stop, comprehensive, and compact source for foundational concepts in behavioral research, and can serve as a stand-alone text or as a supplement to research readings in any doctoral seminar or research methods class. This book is currently used as a research text at universities on six continents and will shortly be available in nine different languages.




Rockbolting


Book Description

Rockbolting: Principles and Applications brings current theoretical and practical developments in the most widely used support device for underground rock excavations. Today, one cannot find any rock excavation project that does not use rockbolts for rock support. The worldwide annual assumption of rockbolts is in the billions, with pieces applied to mines, tunnels and other types of geotechnical projects for rock and soil reinforcement. The text is based on over 25 years of experience of the author both as academic and practitioner. The book introduces the principles and background concepts of rock support, and then offers a comprehensive overview of the mechanics of rockbolting, as well as current rock bolt types such as mechanical, grouted, self-drilling, grouted cables, frictional and yield rockbolts. Installation and performance assessment are covered next including load-displacement curves and energy-absorption capacities. Two chapters on design and quality control, respectively, cover failure mechanics, the selection process and the connections with other supporting devices. On quality control, the author explains the usual tests and displacement measurements. The final chapter brings current case studies that combine the concepts presented in the whole book. The book is a professional reference for engineers in the mining and geotechnical industries and can be used as research material for academics in rock mechanics and stability studies. - Offers theoretical knowledge on rock bolts and rockbolting - Covers the standard and most recent types of rockbolts - Includes information on rockbolting in high stress rock - Presents case studies that introduce practical applications in several conditions










Letter from Birmingham Jail


Book Description

A beautiful commemorative edition of Dr. Martin Luther King's essay "Letter from Birmingham Jail," part of Dr. King's archives published exclusively by HarperCollins. With an afterword by Reginald Dwayne Betts On April 16, 1923, Dr. Martin Luther King Jr., responded to an open letter written and published by eight white clergyman admonishing the civil rights demonstrations happening in Birmingham, Alabama. Dr. King drafted his seminal response on scraps of paper smuggled into jail. King criticizes his detractors for caring more about order than justice, defends nonviolent protests, and argues for the moral responsibility to obey just laws while disobeying unjust ones. "Letter from Birmingham Jail" proclaims a message - confronting any injustice is an acceptable and righteous reason for civil disobedience. This beautifully designed edition presents Dr. King's speech in its entirety, paying tribute to this extraordinary leader and his immeasurable contribution, and inspiring a new generation of activists dedicated to carrying on the fight for justice and equality.
