The Marine Strategy Framework Directive has officially stated as soon as 2008 the anthropogenic noise due to shipping were to be mitigated. The policy makers, the yards and the ship owners still strongly rely on the expert studies and guidelines to find the appropriate methodology to assess and then mitigate the acoustic pollution impact shipping on the marine biota. To address this issue, the project AQUO “Achieve QUieter Oceans by shipping noise footprint reduction” (www.aquo.eu) started in October 2012 for 3 years. The AQUO project was built in the scope of FP7 European Research Framework. It involves 13 partners from 8 European countries, mixes academic experts, industry representatives from yard, classification society and other acoustic and bio-acoustic specialized bodies. Addressing the anthropogenic noise pollution into the marine biota is an increasing concern which is logically paired with the increasing commercial maritime traffic. The IMO itself has recently issued a first draft guideline, to be followed up during the next MEPC, addressing this matter. In parallel to the different achievements that are effective or in progress by standardization bodies or other delegated or assigned work group, the AQUO project aims to finally issue guidelines to be taken as methodological tools. The multi-disciplinary team of this project aims to comply with expectations from the different stakeholders. First, an overview of the project is given. The objectives and the related project structure are detailed so as to better understand which axes are chosen and studied. Secondly, it is here proposed to share the recent outcomes of AQUO project. The current status of applied knowledge, related legal decisions as well as standards empowerment are essential to identify the remaining needs and consequent expected efforts. Drawing first the background rationales the noise footprint concept is then detailed. The process followed towards the main objective of mitigating the anthropogenic noise from shipping will be partly revealed and completed by the expected future work to be achieved by 2015.

Human-generated underwater noise and its effect on marine biota is recognized as an important issue. Boat noise can affect the communication success of fish species that use sounds for spawning purposes. During the reproductive period, males of the black drum Pogonias spp. produce calls ranging from 90 Hz to 300 Hz. In the Mar Chiquita coastal lagoon (Buenos Aires, Argentina), Pogonias courbina is one of the primary fishing species. Although no regulation is directly applied to protect it, a ban protects the reproductive period of other fish species during weekdays. Here, we investigated the potential effect of boat noise on P. courbina vocalizations through a passive acoustic method. Acoustic data were collected, and P. courbina calls were identified and counted. The files with boat noise passages were categorized into classes according to their noise frequency range (A = below 700 Hz, B = over 700 Hz, and C = below and above 700 Hz). The fish call rate was lower in files where boat noise overlapped the fish call frequency (Classes A and C). Only boat noise from Class C was significantly reduced during days with the active fishing ban. These results suggest that anthropogenic noise may affect the P. courbina call rate and underline the importance of including the evaluation of anthropogenic noise in the current management of the area.

This review focuses on providing the history of measurement efforts to quantify and characterize the compounds of reactive mercury (RM), and the current status of measurement methods and knowledge. RM collectively represents gaseous oxidized mercury (GOM) and that bound to particles. The presence of RM was first recognized through measurement of coal-fired power plant emissions. Once discovered, researchers focused on developing methods for measuring RM in ambient air. First, tubular KCl-coated denuders were used for stack gas measurements, followed by mist chambers and annular denuders for ambient air measurements. For ~15 years, thermal desorption of an annular KCl denuder in the Tekran® speciation system was thought to be the gold standard for ambient GOM measurements. Research over the past ~10 years has shown that the KCl denuder does not collect GOM compounds with equal efficiency, and there are interferences with collection. Using a membrane-based system and an automated system—the Detector for Oxidized mercury System (DOHGS)—concentrations measured with the KCl denuder in the Tekran speciation system underestimate GOM concentrations by 1.3 to 13 times. Using nylon membranes it has been demonstrated that GOM/RM chemistry varies across space and time, and that this depends on the oxidant chemistry of the air. Future work should focus on development of better surfaces for collecting GOM/RM compounds, analytical methods to characterize GOM/RM chemistry, and high-resolution, calibrated measurement systems.

AbstractThis comprehensive review written by experts in their field gives an overview on the current status of incorporating positron emission tomography (PET) into radiation treatment planning. Moreover, it highlights ongoing studies for treatment individualisation and per-treatment tumour response monitoring for various primary tumours. Novel tracers and image analysis methods are discussed. The authors believe this contribution to be of crucial value for experts in the field as well as for policy makers deciding on the reimbursement of this powerful imaging modality.

Policy-makers in many nations of the world are involved in educational reforms. In order to make effective educational decisions for the 21st century, policy-makers need information of a wide variety of kinds, for example, comparative performance data and curriculum information from other nations. National assessments can be valuable, but international surveys provide a broader base of information and allow countries to view their current status and planning within an international perspective. The purpose of this paper is to describe the goals of the Third International Mathematics and Science Study and the steps being followed to insure that the results from the study will meet the diverse informational needs of policy-makers.

As is evidenced by this special supplement of the British Journal of Psychiatry, negative symptoms have become the focus of an increasing research effort. We have recently reviewed this overall body of research in an attempt to understand its current status and to suggest directions for future work from a broad perspective (Pogue-Geile & Zubin, 1988). In contrast, the aim of this paper is to review concisely one specific aspect of this research — namely the prognostic and longitudinal characteristics of negative symptoms. Research findings on this general topic will be reviewed by addressing a series of more specific subquestions, which are outlined below. Throughout, the potential importance of when in the course of the disorder (i.e. during an acute episode or afterward) negative symptoms are assessed will be emphasised (Kay et al, 1986b).

The paper focuses on measuring and quantification of the negative externality of noise pollution generated by freight transport in the Slovak Republic and the Czech Republic. The paper describes negative impacts and significance of noise externalities, whereas it is established that noise causes psychological and physiological harm to affected persons. A separate part of the paper is dedicated to the current status of the European legislation dealing with the issues of the negative externality of noise pollution, in particular Directive 2002/49/EC of the European Parliament and of the Council and Communication COM(2008) 435. The actual measurement of the total, average and marginal costs of noise pollution is implemented in line with the defined methodology and using expert studies defined in the paper. The measurement results show that the costs of the negative externality of noise pollution are high in both countries. According to authors’ calculations, the total costs of the negative externality of noise pollution amount to EUR 100.8 mil in the Czech Republic and EUR 16.9 mil in the Slovak Republic. The paper contains a proposal of internalisation of these costs in the form of performance charges applied to operation of heavy goods vehicles.
