Civil society and the state: Turkey after the earthquake

On 17 August 1999 Turkey was hit by a massive earthquake. Over 17,000 lives were lost and there was extensive damage to Turkey's heartland. This paper examines how various public and private institutions, including state and civil society institutions such as NGOs and the media responded to the needs of earthquake survivors. It documents the extensive involvement of NGOs in the relief efforts immediately after the disaster and examines the impact of such participation on state-civil society relations in the country. The data show that state response to the disaster went through several phases from a period of ineptitude to effective management. The paper credits the media and the NGOs for acting as advocates for survivors and forcing changes at the state level. The paper argues that an ideal response system, which fully addresses the needs of victims, can only be based on state-civil society relations that are both collaborative and adversarial.

突发性环境污染事故应急监测准备与响应

突发性环境污染事故具有不确定性，因此要求应急监测准备工作常备不懈；应急监测准备和响应贯穿于事前、事发、事后几个阶段，包括日常准备、应急监测、结果发布、跟踪监测、经验总结等主要环节。     

最大剪切模量对土动力参数及地震反应的影响

最大剪切模量是影响土的动剪切模量比、阻尼比和土层地震反应的最重要参数之一。通常采用室内应变法来确定最大剪切模量，给出土的动剪切模量比和阻尼比，而采用现场剪切波速法求得的结果则很少见。研究了剪切波速法和应变法所确定的最大剪切模量对土动剪切模量比、阻尼比和土层地震反应的影响，推导了两种方法所确定的动剪切模量比和阻尼比之间的关系式。结果表明：最大动剪切模量对土的动剪切模量比、阻尼比和土层地震反应的影响很显著。

Developing a Standardized Water Quality Index for Evaluating Surface Water Quality1

Abstract: There is a significant need for a science‐based approach to interpret water‐monitoring data and to facilitate the rapid transfer of information to water resource managers and the general public. The water quality Index (WQI) is defined as a single numeric score that describes the surface water quality condition at a particular time and location. The objective of this paper is to describe the WQI concept and the approach for developing an ecoregion‐specific standardized WQI that meets the needs described above. The premise of the proposed WQI is based on categorizing scientifically documented aquatic life responses to changes in instream water chemistry. The method uses an aggregated procedure that matches the entire range of standardized probable biological responses to standardized narrative water quality evaluation categories and standardized rank score categories. The calculation of WQI and decision‐making process are performed within an Excel spreadsheet software program. The article includes examples of the proposed WQI applications that could enhance effective water resource management and facilitate timely communication of water quality conditions to water resource managers and the general public.     

Newspaper response to flood and erosion hazards on the North Lake Erie shore

The study is primarily concerned with newspaper responses to flooding and erosion associated with Great Lakes high water in 1952–1953 and 1972–1974. Underlying the research is a general interest in informing the public more widely on choices available in resource and environmental decision making.     

Blast wave clearing behavior for positive and negative phases

The purpose of the research was to improve prediction of response of buildings to blast waves by including the negative phase and considering clearing of both positive and negative phases. Commonly used structural design practices, which trace their origins to military design manuals, often ignore the negative phase as well as positive phase clearing. For high explosive threats, this approach is conservative in most circumstances. However, negative phase clearing had not previously been studied for blast waves, and the implications for structural response had not been evaluated. This paper presents results of modeling negative phase blast clearing behavior for a typical blast wave and discusses the differences from positive phase clearing. The implications of including positive and negative phase clearing in building blast damage analysis are also investigated through single-degree-of-freedom (SDOF) analyses.Blast waves from explosion sources like a vapor cloud explosion (VCE), pressure vessel burst or high explosive exhibit both positive and negative phases, and the relative magnitude of the positive and negative phases varies among explosion sources and the specific circumstances of each source. A fully reflected blast wave is produced if an incident blast wave were to strike an infinitely tall and wide wall in a normal orientation. Both the positive and negative phases of the blast wave are enhanced by the reflection process. However, when an incident blast wave strikes a wall of finite size in a normal orientation, rarefaction waves are created at the edges of the wall, and the rarefactions sweep down from the roof and inward from sides. The rarefaction waves result in a clearing effect for both the positive and negative phases.Clearing relieves some of the applied blast load on the reflected wall for the positive phase. However, this is not always the case for the negative phase. As shown by the results presented in this paper, clearing may either relieve or enhance the applied negative phase blast load, depending on the duration of the blast wave and the wall dimensions.The impact of negative phase clearing on structural response for generic building components was also investigated. Nonlinear SDOF methods were used to characterize response in terms of peak positive and negative displacements. It was found that the influence of the negative phase is significant and the peak structural response can occur during negative (outward) displacement.
