Noise Management

Airports are required to manage noise impact owing to their requirement to obtain a social license to operate, and to comply with legislation such as the ICAO Balanced Approach and Environmental Noise Directive. Research has however shown that noise management actions and interventions often take a techno-centric approach, are implemented in silos, and that their success beyond noise metrics is rarely evaluated. Moreover, the success of Noise Action Plans in driving long-term noise management outcomes has also been critiqued at a number of levels. In the context of this background, this paper outlines the case for more strategic approaches to noise management and, drawing on the academic strategic literature, outlines approaches to developing such strategies that can be followed by airports. The aim of such approaches is to complement existing noise management guidance by providing step-processes that can aid airports in developing robust, repeatable, evaluable, and successful noise management strategies that are consistent with wider airport strategy and that are sympathetic to the needs of airport residents.

ABSTRACT In this study, we investigate how country-level long-term orientation affects managers' willingness to engage in earnings management and choice of earnings management strategy. Using a comprehensive dataset of 47 countries for the period from 2003 to 2015, we find that firms in long-term-oriented cultures rely relatively more on earnings management through accruals, while firms in short-term-oriented cultures engage in relatively more real earnings management. Furthermore, we find a larger discontinuity around earnings benchmarks in long-term-oriented cultures suggesting that manipulation of accruals enables benchmark beating with high precision.

Red Cockaded Woodpecker

Abstract To mitigate possible negative effects that financial timber rotations for southern pine may have on habitat requirements for red-cockaded woodpeckers, alternative management strategies are investigated using multiple objective linear programming (MOLP). Time streams of timber and habitat are examined. The consequence of providing areas with potential cavity trees on production of timber is explored. Management actions which immediately set aside large areas of land for woodpecker habitat without concern for future changes can lead to short-term increases in habitat that are followed by habitat declines after several decades. Management actions designed to restructure the forest to achieve a long-term sustainable habitat level may initially have a slower increase in habitat, but without subsequent declines. South. J.

Dynamic simulation technology is integrated with mass balance concepts and compartment-flux diagramming to create computer models that estimate contaminant export from watersheds over long and short-term futures under alternative simulated policies of watershed management. The Watershed Ecosystem Nutrient Dynamics (WEND) model, applied to developed watersheds with a mix of urban, agricultural, and forest land-uses, predicted phosphorus (P) export from three watersheds; a 275,000 ha dairy/urban watershed, a 77,000 ha poultry/urban watershed, and a 23,000 ha swine dominated watershed. Urban, agricultural, and forestry activities contribute to P export in different proportions. In all cases the P imports to the watershed exceed total export and P accumulates in watershed soils. Long-term future P export patterns are compared for several watershed management strategies that range from encouragement of rapid urban growth to aggressive environmental protection. The specific response of each watershed to imposed management is unique, but management strategies designed to reduce export of P over the long-term need to consider options that promote P input/output balance. Using this same approach, the Watershed Ecosystem Bacterial Dynamics (WEBD) model assesses the dynamics of bacterial populations in a small case-study watershed over an annual cycle as influenced by dairy farm management actions. WEND and WEBD models integrate the diversity of activities and stakeholders interested in the watershed and promote development of a more holistic understanding of watershed function. Model outputs are designed to assist watershed policy-makers, managers, and planners to explore potential future impacts of management/policy decisions.

Long-term agricultural experiments such as the Temperate Pastures Sustainability Key Program (TPSKP) present significant challenges in the areas of planning and design, conduct, analysis and reporting. This paper concentrates on 2 aspects, namely, the experimental design and the statistical analysis. For long-term agricultural experiments which examine the effects of management strategies over time, an enumeration of the initial biodiversity is essential and permits the allocation of treatments to plots in such a way that potential bias in the estimation of treatment effects due to lack of uniformity in experimental units (plots) is reduced in the covariate analysis. Spatial replication is considered essential and the design should include at least 2 starting dates for management strategies so that the possible interaction between the year of start and the management strategy can be described. The data resulting from repeated measurement of herbage mass of major individual species or species groups represent a longitudinal data set with complexity due to the staggered commencement of treatments and also in part due to the nature of some of the strategies (closure and cuts). The analysis presented is the cubic smoothing spline approach of Verbyla et al. (1999) which integrates cubic splines, random coefficients, covariance modelling and estimation of systematic deviation. This approach, based on linear mixed models and using residual maximum likelihood (REML) has the flexibility to cope with the staggered imposition of management strategies and permits the partitioning of trends into smooth and non-smooth components, thereby quantifying species persistence and seasonal influence under each management strategy.

<i>Abstract</i>.—Overexploitation of wild sturgeon (Acipenseridae) species worldwide for caviar has led to a shift in harvest to Paddlefish (Polyodontidae: <i>Polyodon spathula</i>), another Acipenseriform species and a state-managed fish still harvested commercially in eight states within the United States. State game and fish agencies with commercial fisheries are increasingly being pressured to open or extend commercial Paddlefish fisheries under their respective jurisdictions. In addition to the increased needs for a multi-state management framework among states, new demands on the Paddlefish within states and its high vulnerability to overharvest require more proactive, innovative, and restrictive management approaches than the frequently liberal regulations of the past. This paper describes proactive management strategies implemented by state fisheries agencies in Alabama and Mississippi for the long-term conservation of their Paddlefish fisheries. The management actions implemented fall into three broad areas: (1) fishing areas, seasons, and participation; (2) fishing and harvest restrictions; and (3) licensing fees, reporting, and training. Actions taken under (1) included defining Paddlefish management areas, establishing specific harvest seasons and daily harvest times, and limiting the number of harvesters. Actions under (2) included enacting length limits and female-only harvest (Alabama), implementing harvest (carcass) tags to track fish and roe, and establishing gear restrictions to reduce unintended Paddlefish mortality. Actions under (3) included establishing rational permit requirements and fees, establishing specific harvest reporting requirements, and providing informational training to aid in angler compliance. Although there are many similarities in the approaches taken, each state has tailored its regulations to its political and biological situation. Alabama and Mississippi will be evaluating the effectiveness of their approaches and needed adaptations will be made to ensure long-term sustainability of the Paddlefish.

Coral reefs provide important ecosystem services to coastal communities. The Archipelago of Tinhar?e andBoipeba, Bahia, Brazil, are mostly surrounded by fringing reefs, which have undergone several chronichuman impacts. The objective of the present study was to apply an ecosystem-based approach byanalyzing the ecosystem services provided by the coral reefs of the Archipelago of Tinhar?e and Boipeba inorder to support management actions and serve as a tool for coastal management. Ecosystem serviceswere assessed through the observation of environmental indicators of their occurrence and by using asuite of models from the Integrated Valuation of Environmental Services and Tradeoffs (InVEST) softwarecombined with data from the Atlantic and Gulf Rapid Reef Assessment (AGRRA) protocol database. Theservices of greatest occurrence were food provision, habitat maintenance, shoreline protection andrecreation. While the main stressful factors were tourism activities, the absence of a sewage system andfisheries. The coral reefs presented potential for shoreline protection along 50.5% of the islands. Moreover,46.8% of the shoreline would present moderate to high vulnerability in case of coral reef disappearance.The coincidence of areas with high risk of loss in the capacity to provide services and highvulnerability in the scenario of absence of reefs is concerning. Thus, the current model for tourism usedin the area should be altered, as should new management strategies be implemented, which can bringbenefits and avoid reef decline.

Petroclival Meningiomas

OBJECTIVEA thorough investigation of the long-term outcomes and chronological changes of multimodal treatments for petroclival meningiomas is required to establish optimal management strategies. The authors retrospectively reviewed the long-term clinical outcomes of patients with petroclival meningioma according to various treatments, including various surgical approaches, and they suggest treatment strategies based on 30 years of experience at a single institution.METHODSNinety-two patients with petroclival meningiomas were treated surgically at the authors’ institution from 1986 to 2015. Patient demographics, overall survival, local tumor control rates, and functional outcomes according to multimodal treatments, as well as chronological change in management strategies, were evaluated. The mean clinical and radiological follow-up periods were 121 months (range 1–368 months) and 105 months (range 1–348 months), respectively.RESULTSA posterior transpetrosal approach was most frequently selected and was followed in 44 patients (48%); a simple retrosigmoid approach, undertaken in 30 patients, was the second most common. The initial extent of resection and following adjuvant treatment modality were classified into 3 subgroups: gross-total resection (GTR) only in 13 patients; non-GTR treatment followed by adjuvant radiosurgery or radiation therapy (non-GTR+RS/RT) in 56 patients; and non-GTR without adjuvant treatment (non-GTR only) in 23 patients. The overall progression-free survival rate was 85.8% at 5 years and 81.2% at 10 years. Progression or recurrence rates according to each subgroup were 7.7%, 12.5%, and 30.4%, respectively.CONCLUSIONSThe authors’ preferred multimodal treatment strategy, that of planned incomplete resection and subsequent adjuvant radiosurgery, is a feasible option for the management of patients with large petroclival meningiomas, considering both local tumor control and postoperative quality of life.

Modelling Approach

The paper illustrates analysis of the assumptions of the statistical component of a hybrid modelling approach for predicting environmental extremes. This shows how to assess the applicability of the approach to water quality problems. The analysis involves data on stream acidity from the Birkenes catchment in Norway. The modelling approach is hybrid in that it uses: (1) a deterministic or process-based description to simulate (non-stationary) long term trend values of environmental variables, and (2) probability distributions which are superimposed on the trend values to characterise the frequency of shorter term concentrations. This permits assessment of management strategies and of sensitivity to climate variables by adjusting the values of major forcing variables in the trend model. Knowledge of the variability about the trend is provided by: (a) identification of an appropriate parametric form of the probability density function (pdf) of the environmental attribute (e.g. stream acidity variables) whose extremes are of interest, and (b) estimation of pdf parameters using the output of the trend model.
