Sources Of Uncertainty

Abstract Large scale noise exposure modelling is used in epidemiological research projects as well as for noise mapping and strategic action planning. Such calculations should always be accompanied by an assessment of uncertainty, on the one hand to check for systematic deviations and on the other hand to investigate the sources of uncertainty to address them in future studies. Within the SiRENE (Short and Long Term Effects of Transportation Noise Exposure) project, a large scale nationwide assessment of Switzerland’s road, railway, and aircraft noise exposure was conducted for the year 2011. In the present follow-up study, we equipped 180 sleeping and/or living room windows with sound level meters for one week. The resulting dataset was used to validate noise exposure modelling within SiRENE. For the noise metric LDEN the comparison revealed a difference of 1.6 ± 5 dB(A) when taking all measurements into account. After removing measurement sites with noise mitigation measures not considered in the modelling, the difference to the calculation was reduced to 0.5 ± 4 dB(A). As major sources of uncertainty, the position accuracy and topicality of infrastructure and building geometries, the traffic modelling as well as the acoustic source and propagation models were identified.

A year ago the World Stroke Organisation (WSO) highlighted the enormous global impact of the COVID-19 pandemic on stroke care. In this review we consider a year later where we are now, what the future holds, and what the long term effects of the pandemic will be on stroke. Stroke occurs in about 1.4% of patients hospitalised with COVID-19 infection, who show an excess of large vessel occlusion and increased mortality. Despite this association, stroke presentations fell dramatically during the pandemic, although emerging data suggests that total stroke mortality may have risen with increased stroke deaths at home and in care homes. Strategies and guidelines have been developed to adapt stroke services worldwide, and protect healthcare workers. Adaptations include increasing use of telemedicine for all aspects of stroke care. The pandemic is exacerbating already marked global inequalities in stroke incidence and mortality. Lastly the pandemic has had a major impact on stroke research and funding, although it has also emphasised the importnace of large scale collaborative research initiatives.

AbstractIn 2014 the three-year interdisciplinary study SiRENE (Short and Long Term Effects of Traffic Noise Exposure) was launched in Switzerland. The goal of SiRENE is to investigate acute, short- and long-term e_ects of road, railway and aircraft noise exposure on annoyance, sleep disturbances and cardio-metabolic risk.The study is based on a detailed Swiss-wide assessment of transportation noise exposure, including diurnal distributions. The exposure analysis comprises current as well as historical exposure calculations for up to 20 years in the past.We present the major challenges of compiling sufficient data to support a Swiss-wide model for all buildings and including all transport infrastructure as a basis for the subsequent SiRENE sound exposure analysis for the years 2011, 2001 and 1991. The task is particularly challenging for the early years due to poor data quality and/or lack of availability. We address the integration of geo-referenced input datasets from various sources and time periods, the assignment of tra_c noise exposure from façade points to dwelling units, as well as the processing of traffic information and statistics. Preliminary results of the noise exposure calculations are presented.

Short Term Effects

Ambient scents are being increasingly used in different service environments. While there is emerging research on the effects of scents, almost nothing is known about the long-term effects of consumers’ repeated exposure to ambient scents in a service environment as prior studies on ambient scents have been lab or field studies examining short-term effects of scent exposure only. Addressing this limitation, we examine the short- and long-term effects of ambient scents. Specifically, we present a conceptual framework for the short- and long-term effects of nonconsciously processed ambient scent in olfactory-rich servicescapes. We empirically test this framework with the help of two large-scale field experiments, conducted in collaboration with a major German railway company, in which consumers were exposed to a pleasant, nonconsciously processed scent. The first experiment demonstrates ambient scent’s positive short-term effects on consumers’ service perceptions. The second experiment—a longitudinal study conducted over a 4-month period—examines scent’s long-term effects on consumers’ reactions and demonstrates that the effects persist even when the scent has been removed from the servicescape.

We evaluated the effects of disturbance on stream benthic macroinvertebrates at the ecological scales of time, stream size, and burn extent in six segments of Cache Creek over the first 10 postfire years. Postfire changes in macroinvertebrate taxa richness, density, and dominant taxa in the burn streams were significantly different from those in the reference stream. Chironomidae and Baetis typically comprised 40–60% of the macroinvertebrate assemblages of burned streams but only 15–18% of the assemblage in the reference site. Coefficients of variation for the 10-year period indicated that richness, density, biomass, and Baetis abundance were more variable (1.2–3.5 times higher) in the burn streams than in the reference stream and that variability in Chironomidae abundance in burn sites increased with stream size. Fire effects were not attenuated progressively with increasing stream size, probably because the proportion of the catchment burned did not decrease. However, similar-sized streams in which 68–71% of their catchments burned were more severely disturbed than those in which only 39–47% burned. Long-term effects on the macroinvertebrate community were due largely to the loss of terrestrial vegetation and increased runoff, which caused severe alterations in stream channel conditions and large-scale bedload movement.

Information from the records of the various agencies on control of the sea lamprey (Petromyzon marinus) was summarized from the early approach to control by mechanical or electrical barriers and chemical toxicants. While fish kill has been an inescapable consequence of the program, information available for migratory species has shown no large-scale detrimental effects. The only reportable instance of damage to a resident stream species has been the near loss of the stonecat (Noturus flavus) from tributaries to the southwest corner of Lake Superior, resulting from chemical treatments. Although no similar occurrences were recognized, available documentation proved inadequate to record long-term effects on these vulnerable species. As long as existing control methods continue, no matter the precautions taken, fish populations will be affected. Whether or not this remains a tenable situation is a question for this symposium and the future.Key words: weirs, chemicals, fish kills, sea lamprey, Petromyzon marinus; Catostomus catostomus, Catostomus commersoni, Noturus flavus, Salvelinus fontinalis

Modeling Process

The principles of mass balance, compartment-flux diagramming, and dynamic simulation modeling are integrated to create computer models that estimate phosphorus (P) export from large-scale watersheds over long-term futures. These Watershed Ecosystem Nutrient Dynamics (WEND) models are applied to a 275,000 ha dairy-documented watershed and a 77,000 ha poultry-dominated watershed in northeastern USA. Model predictions of present-day P export loads are consistent with monitoring data and estimates made using P export coefficients. For both watersheds P import exceeds P export and P is accumulating in the agricultural soils. Agricultural and urban activities are major contributors to P export from both watersheds. Continued urban growth will increase P export over time unless wastewater management is substantially enhanced and/or rates of urban growth are controlled. Agriculture cannot rely solely on the implementation of increasingly stringent conservation practices to reduce long-term P export but mustconsider options that promote P input/output balance. The WEND modeling process is a powerful tool to integrate the diversity of activities in watersheds into a holistic framework. Model outputs are suited to assist managers to explore long-term effects of overall watershed management strategies on P export in comparison to environmental and economic goals.

The 2011 Great East Japan earthquake has shown all too clearly that disaster management and mitigation measures seen from the viewpoint of protecting society are not sufficient for addressing a national crisis such as the projected Nankai Trough earthquake or Tokyo inland earthquake whose damage is expected to exceed the present estimated damage. Our study explores the weakness against disasters in how modern Japanese society uses “reverse thinking” in which investigates studying how large-scale disasters may adversely affect society and increase damage effectively. This process profiles the worst disaster scenarios that could conceivably lead to a national crisis. Classifying these worst scenarios, we suggest policies to the problems that are common to many scenarios, and we present action plans for individual problems. First, we conduct workshops for identifying damage magnification factors and evaluating their importance under the categories of human damage, property damage, and damage to social functions, unifying the awareness of research organization. Second, we have researchers on 1) mortality, 2) tsunami inundation, 3) liquefaction, 4) capital function, 5) evacuation, 6) required assistance, 7) lifelines, 8) high buildings, 9) information networks, 10) government systems, and 11) economic systems analyze damage magnification conditions due to hazard, vulnerability and measure aspects. Third, we sort potential final consequences and separate them based on commonality, and propose new policies and concrete action plans for preventing the occurrence of worst-case scenarios. This research is expected to give new paradigms in disaster management science and new ways of policy making and action planning that will minimize the undesirable consequences of catastrophic earthquake and tsunami and yield new knowledge on disaster processes and damage magnification scenarios. Most importantly, we conclude that it is necessary to have a new Japanese governmental organization, such as a Ministry of Disaster Resilience or a Disaster Resilience Management Agency, handle these national crises.

Abstract In the framework of the European Directive 2002/49/EC, from 2012 to 2016, several cities in Greece have completed noise strategic maps with noise action plans that usually define the main strategies to reduce the noise residents are exposed to and introduce and preserve “quiet zones”. Several medium urban agglomerations in Greece (Volos, Larissa, Chania, Heraklion, Corfu, Agrinio, Thessaloniki) have been chosen to also analyse the sound qualities of the soundscapes of specific urban neighbourhoods in order to generate recommendations for the urban design of the soundscapes of these agglomerations in a manner that complements conventional noise mitigation measures. The general principle of this approach is to relate quantitative data (e.g., from measurements, acoustic simulations, urban forms, topography, and traffic model) with qualitative data (e.g., from type of sources, interviews, reports on environmental noise perception) by creating quantitative and qualitative maps. The aim of this study is to propose possible action tools to the relevant authorities aiming at diminishing noise levels in affected areas and also to provide solutions towards a sustainable sound environment both in space and time. This paper presents the main current methodology, selected important results proposed for the urban agglomerations of a typical Southeast Mediterranean country such as Greece.
