The Effectiveness of Coastal Zone Management in the United States

The Coastal Zone Management Effectiveness Study was undertaken between 1995 and 1997 to determine how well state coastal management programs in the United States were implementing five of the core objectives of the U.S. Coastal Zone Management Act (CZMA). The five core objectives studied were: (1) protection of estuaries and coastal wetlands; (2) protection of beaches, dunes, bluffs and rocky shores; (3) provision of public access to the shore; (4) revitalization of urban waterfronts; and (5) accommodation of seaport development (as an illustration of the policy to give priority to coastal-dependent uses). Separate articles in this issue of Coastal Management report the findings of the five studies, each dealing with one of the core objectives. Each of the articles assesses issue importance, processes and tools used, and the limited outcome data available for that objective. This article provides an overview of the purposes of the study, the methodology used, the summary findings of each study, and overall conclusions and recommendations of the study team. State coastal programs are found to be effective in addressing the five CZMA objectives examined, but this conclusion is based on very limited information about program outcomes. A more definitive conclusion will require better outcome information. Coastal managers in the United States have not agreed upon indicators of success, which severely inhibits systematic and sustained collection of outcome information. A national outcome monitoring and performance evaluation system is recommended to address these deficiencies and allow better determinations of program effectiveness in the future.     

自发高血压大鼠心脏功能及血压的增龄性变化

４～１８周之雄性自发高血压大鼠（ＳＨＲ）与正常血压（ＷＫＹ）鼠各分为５个年龄组。乙醚麻醉下测取有关心功能指标，并以短暂的主动脉阻闭所得到的左室发展压峰值（ｐＤｅｖＰ，由左室收缩压减去左室舒张末压获得）作为左室最大压力产生能力的指标。实验结果显示：①各年龄组ＳＨＲ之动脉收缩压、舒张压、平均动脉压、左室收缩压均高于同龄组ＷＫＹ鼠（Ｐ＜０．０５）。ＳＨＲ之上述指标随年龄增长而增高。②各年龄组ＳＨＲ之ｐＤｅｖＰ均高于同龄组ＷＫＹ鼠（Ｐ＜０．０５）。ＳＨＲ之ｐＤｅｖＰ随年龄增长而增大。     

Walking frequency, cars, dogs, and the built environment

To explain walking propensity or frequency, empirical studies have generally used two sets of explanatory variables, namely, socio-demographic variables and built environment variables. They have generally shown that both socio-demographic characteristics and built environment characteristics are associated with walking propensity. We examine the traditional walkability variables that encompass density, mix of uses, and network connectivity in New Jersey, using a statewide sample including an oversample of Jersey City. We estimate a two-stage least squares model using a conditional mixed process that combines an ordered probit model of walking frequency in the second stage based on a truncated regression of car ownership in the first stage. Our results show that built environment variables have some small effects, mainly from better network connectivity associated with increased walking frequency. One of our key findings is that built environment features also work indirectly via how they influence car ownership. In general, we find sufficient evidence that suggests fewer cars are owned in areas with more walkable built environment features. The other key variable that we control for is whether a household owns a dog. This also proved to be strongly associated with walking suggesting that dog ownership is a necessary control variable to understand the frequency of walking.     

Culture,Ethnography, and Marine Affairs

Abstract

Marine and coastal zone policy represents a collaboration of people managing and people managed. This paper takes a holistic stance in suggesting that marine communities are viewed properly as networks of focused interest groups, policymakers, professionals, and publics. The interplay between culture and marine and coastal policy is appropriately one topic of applied social research. Seven ethnographic studies in this domain are introduced in this theme issue and help us to understand sociocultural processes and institutions bearing on marine affairs.     

Optimization of emergency crossovers and signals for emergency operations in rail rapid transit

This paper presents a methodology for designing rail transit systems to meet operating requirements when track maintenance or failure cause sections of tracks to be unavailable for service. The methodology can be also used to establish the requirements for the continuity of operations during construction. The main objective of the paper is to develop a tool which performs trade-offs between system costs and level of services during emergencies/construction. Several alternatives, including various signal and control systems, number and types of crossovers and corresponding operating strategies, are developed and evaluated against capital investments. Operating measures and strategies for the selected alternative can be recommended before the design phase is completed, because the designer, by using this methodology, is aware of the capacities attained during emergencies and construction.     

DRAG-ALZ-1, a first model of monthly total road demand,accident frequency,severity and victims by category,and of mean speed on highways,Algeria 1970–2007

We construct a first country-wide model of demand for road use and of road safety outcomes for Algeria making use of the DRAG-type framework and of flexible regression estimation methods that make a demonstrable difference to the quality of our results. We imply that the availability of high quality Algerian data could make it worthwhile not only to consider updates of the model with longer data series but also to study variants of the model, notably with disaggregation of freight activities across industrial sectors.     

Boundaries of the coastal zone: A survey of state laws

Abstract

A survey of coastal state legislation reveals several types of statutes affecting activities occurring in coastal regions: Coastal management statutes, wetland statutes, and shoreline statutes. Each coastal state has adopted methods to delineate coastal areas or features, whether an entire coastal zone, a limited feature such as wetlands, or shorelands. Boundary delineation is done according to linear measurements, political boundaries, roads and highways, vegetation, elevation, tidal flow, and other factors. An appendix is provided containing state statutory provisions relating to boundary‐delineation techniques.     

Public law litigation and marine affairs: The boldt decision

Abstract

The management and conservation of the marine environment and its natural resources are increasingly understood to be issues of public policy with consequences for society at large. On a variety of dramatic occasions over the last decades, the federal judiciary has departed from its traditionally passive role in the shaping of social policy. This paper examines a critical marine controversy, the Boldt Decision (U.S. v. Washington 1974), to illustrate and evaluate nontraditional judicial behavior. The first two sections introduce Indian‐United States treaties concerning Pacific Northwest salmon resources, and the unfolding of the Boldt Decision. A third section argues that a “public law”; model of litigation fits the legal events of the Boldt Decision. A fourth section addresses the competence of the Boldt court as it is manifest in judicial organization, analysis, and implementation. A final section comments on the potential for public law litigation elsewhere in the governing of marine affairs.
