Community Perceptions of a World Heritage Nomination Process: The Ningaloo Coast Region of Western Australia

The remote Ningaloo Coast region, the location of Australia's largest fringing coral reef, was designated as World Heritage (WH) in 2011 based on its outstanding natural values. In the past, the WH nomination process predominantly involved experts and state officials. More recently, local community involvement has become a required part of the process, representing a move toward participatory governance that can potentially influence WH designation. Understanding community perceptions of the WH nomination process provides insights into the consequences of community involvement. Interviews were conducted with key local community members involved in the Ningaloo Coast WH nomination. Interviews focused on the perceptions and experience of the nomination process and local meanings of WH designation. Results indicated that while there was support for WH designation, the nomination process was seen as controversial. Community involvement was dominated by local political and social concerns, mistrust, misinformation, and perceived unfairness. Concerns were influenced by past and current government actions and decision-making in the region. The article identifies some challenges associated with local community involvement in a WH nomination process. These challenges raise questions about participatory governance and how local community's engage in the WH nomination process for coastal regions identified by experts as globally significant.     

Integrated Environmental Modeling and Assessment of Coastal Ecosystems: Application for Aquaculture Management

This article presents an approach that couples coastal ecosystem modeling with integrated environmental assessment methodologies to support coastal management. The focus is to support the development of an ecosystem approach to aquaculture management including interactions with watershed substance loading. A Chinese bay, with intense aquaculture and multiple catchment uses, and where significant modeling efforts were undertaken is used as a case study. The ecosystem model developed for this bay is used to run scenarios that test the local management strategy for nutrient reduction. The corresponding ecological and economic impacts of the managers’ scenarios are analyzed by means of the Differential Drivers-Pressure-State-Impact-Response (ΔDPSIR) analysis. Emphasis is given to the analysis of the eutrophication process in the bay including present eutrophic condition and the expected changes due to the simulated scenarios. For this purpose, the Assessment of Estuarine Trophic Status (ASSETS) screening model is a valuable tool to interpret and classify the data and model outputs regarding eutrophication condition and to evaluate the manageable level of the nutrient loading entering in the bay.     

An Alert System for Beach Hazard Management in the Balearic Islands

A real-time beach hazard level associated with nearshore hydrodynamics is presented in this article. The suitability of the discussed alert system is illustrated via its application to fifteen beaches in the Balearic Islands (Western Mediterranean Sea) providing nearshore safety conditions for beach safety manager. The system provides daily forecasts of nearshore wave conditions using the deep water wave forecasts. The shallow water wave data (wave height, period, and direction) together with the morphology of the site (presence of bars, capes, beach type, etc.) are used to define a hazard level (low, medium, and high) associated with local conditions. The resulting hazard level is transmitted via SMS to lifeguards and local authorities for real-time beach management. The low computational cost of this system after the initial implementation and subsequent calibration results in a very suitable approach for beach management in order to mitigate risks related to local hydrodynamics.     

Duplin river estuarine sanctuary—a description

Abstract

The Duplin River Estuarine Sanctuary was dedicated by Governor George Busbee of Georgia in December 1976. The sanctuary includes the entire Duplin river, related wetlands, and much of the contributing uplands, which extend over 7500 acres. Much of the upland lies on Sapelo Island, neighboring a state wildlife management area, a state natural area, and a community of black families that have lived and worked on the island for many generations. The sanctuary was acquired, in part, with funds from the National Oceanic and Atmospheric Administration, and will be managed for research and educational purposes. The management policy will be designed to avoid artificial or manipulative management control, to protect natural processes and systems, and to promote attainment of scientific objectives.

空间分析及基础技术应用是研究集装箱运输的必要手段.大部分交通运输数据集由不同出处、关联性不强的原始数据组成,因而很难得到其空间分布特点.同时,集装箱路径优化和市场可达性在缓解集装箱运输拥堵方面的作用日益凸显.本文基于可用数据库对美国集装箱运输OD分布进行分析.以美国水陆运输理事会的公共货票数据库数据作为内陆铁路线路优化的原始输入.利用类似河流管理的方法优化集装箱运输路径.从进口集装箱的数据集看,从亚洲或者欧洲出发经由北美港口到达美国的集装箱,大部分经由太平洋海岸到达内陆市场.横渡太平洋贸易的进口集装箱枢纽港主要是洛杉矶、长滩和西雅图.横渡大西洋贸易的进口集装箱枢纽港主要是纽约、新泽西州和萨凡纳乔治亚州.太平洋海岸和密西西比河谷地区包括阿尼阿波利斯、芝加哥、堪萨斯城、孟菲斯、达拉斯和休斯顿的流量很高.从美国中西部至东部的集装箱流多经过纽约、新泽西州和诺福克最后到达芝加哥.对于集装箱运输OD分布的分析可以为高成本和多式联运相关分析提供数据基础.

A sequential approach to exploiting the combined strengths of SP and RP data: Application to freight shipper choice

The possibility of and procedure for pooling RP and SP data have been discussed in recent research work. In that literature, the RP data has been viewed as the yardstick against which the SP data must be compared. In this paper we take a fresh look at the two data types. Based on the peculiar strengths and weaknesses of each we propose a new, sequential approach to exploiting the strengths and avoiding the weaknesses of each data source. This approach is based on the premise that SP data, characterized by a well-conditioned design matrix and a less constrained decision environment than the real world, is able to capture respondents' tradeoffs more robustly than is possible in RP data. (This, in turn, results in more robust estimates of share changes due to changes in independent variables.) The RP data, however, represent the current market situation better than the SP data, hence should be used to establish the aggregate equilibrium level represented by the final model. The approachfixes the RP parameters for independent variables at the estimated SP parameters but uses the RP data to establish alternative-specific constants. Simultaneously, the RP data are rescaled to correct for error-in-variables problems in the RP design matrixvis-à- vis the SP design matrix. All specifications tested are Multinomial Logit (MNL) models.The approach is tested with freight shippers' choice of carrier in three major North American cities. It is shown that the proposed sequential approach to using SP and RP data has the same or better predictive power as the model calibrated solely on the RP data (which is the best possible model for that data, in terms of goodness-of-fit figures of merit), when measured in terms of Pearson's Chi-squared ratio and the percent correctly predicted statistic. The sequential approach is also shown to produce predictions with lower error than produced by the more usual method of pooling the RP and SP data.     

Integrating Naval Aviation Maintenance Training with Sailors' Proficiency Qualification and Its Correlation with Improved Weapon System Readiness

A core role for human systems integration is providing support of weapon systems operational effectiveness with optimal human performance (HP). When applied to the readiness of an aviation squadron, this focus on enhanced operational HP translates into ensuring that highly trained and proficient maintenance technicians are resident in these warfighting units. A key objective of the Naval Aviation Enterprise (NAE) Total Force Readiness program is to bridge Core Capabilities to Missions. This is accomplished through the linking of Navy Mission Essential Task Lists (NMETLs) to Skill Sets and Performance Standards for its future workforce. These goals can be accomplished from Initial Development to Deployment of a weapons system through its operational and support phases of the Department of Defense acquisition process using a mission/task-centric approach to Manpower, Personnel, and Training (MPT) requirements, with NMETLs as the operational thread. This paper will describe a life-cycle MPT analytic environment with its task-level links to systems and human engineering disciplines. A systematic approach to accessing and training a proficient maintenance workforce is presented, focusing on task-based maintenance training solutions for optimal unit readiness and mission capabilities. An innovative analytic framework from various skills-based manpower analysis studies will be cited as a means to transform system and unit MPT performance for Total Force Readiness. Enhanced by a Qualified and Proficient Technician methodology, a capability (missions) and competency (proficient) future workforce with skills-efficient maintainers will be best suited to achieving optimal readiness of weapons systems within the NAE.
