Book Description
Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.

Book Description
A new interdisciplinary interest has risen to study interconnections between oral tradition and book culture. In addition to the use and dissemination of printed books, newspapers etc., book culture denotes manuscript media and the circulation of written documents of oral tradition in and through the archive, into published collections. Book culture also intertwines the process of framing and defining oral genres with literary interests and ideologies. The present volume is highly relevant to anyone interested in oral cultures and their relationship to the culture of writing and publishing. The questions discussed include the following: How have printing and book publishing set terms for oral tradition scholarship? How have the practices of reading affected the circulation of oral traditions? Which books and publishing projects have played a key role in this and how? How have the written representations of oral traditions, as well as the roles of editors and publishers, introduced authorship to materials customarily regarded as anonymous and collective?

Book Description
Investing in Resilience: Ensuring a Disaster-Resistant Future focuses on the steps required to ensure that investment in disaster resilience happens and that it occurs as an integral, systematic part of development. At-risk communities in Asia and the Pacific can apply a wide range of policy, capacity, and investment instruments and mechanisms to ensure that disaster risk is properly assessed, disaster risk is reduced, and residual risk is well managed. Yet, real progress in strengthening resilience has been slow to date and natural hazards continue to cause significant loss of life, damage, and disruption in the region, undermining inclusive, sustainable development. Investing in Resilience offers an approach and ideas for reflection on how to achieve disaster resilience. It does not prescribe specific courses of action but rather establishes a vision of a resilient future. It stresses the interconnectedness and complementarity of possible actions to achieve disaster resilience across a wide range of development policies, plans, legislation, sectors, and themes. The vision shows how resilience can be accomplished through the coordinated action of governments and their development partners in the private sector, civil society, and the international community. The vision encourages “investors” to identify and prioritize bundles of actions that collectively can realize that vision of resilience, breaking away from the current tendency to pursue disparate and fragmented disaster risk management measures that frequently trip and fall at unforeseen hurdles. Investing in Resilience aims to move the disaster risk reduction debate beyond rhetoric and to help channel commitments into investment, incentives, funding, and practical action

Book Description
Presents 80 documents selected to reflect Eric Voegelin's theory that in Western civilization basic political symbolizations tend to be variants of the original symbolization of Judeo-Christian religious tradition. These documents demonstrate the continuity of symbols preceding the writing of the Constitution and all contain a number of basic symbols such as: a constitution as higher law, popular sovereignty, legislative supremacy, the deliberative process, and a virtuous people.
