Noise Management

Maritime transportation is recognized to have advantages in terms of environmental impact compared to other forms of transportation. However, an increment in traffic volumes will also produce an increase in noise emissions in the surroundings for a greener source, as ports are frequently surrounded by urban areas. When more sources or higher noise emissions are introduced, the noise exposure of citizens increases, and the likelihood of official complaints rises. As a consequence, among the most demanding aspects of port management is effective noise management aimed at a reduction in the exposure of citizens while ensuring the growth of maritime traffic. At the same time, the topic has not been thoroughly studied by the scientific community, mostly because port areas are challenging from a noise management point of view; they are often characterized by a high degree of complexity, both in terms of the number of different noise sources and their interaction with the other main transportation infrastructure. Therefore, an effective methodology of noise modeling of the port area is currently missing. With regard to the INTERREG Maritime Program, the present paper reports a first attempt to define noise mapping guidelines. On the basis of the current state-of-the-art and the authors’ experiences, noise sources inside port areas can be divided into several different categories: road sources, railway sources, ship sources, port sources, and industrial sources. A further subdivision can be achieved according to the working operation mode and position of the sources. This classification simplifies actions of identification of the responsible source from control bodies, in the case that noise limits are exceeded or citizen complaints arise. It also represents a necessary tool to identify the best placing of medium/long-term noise monitoring stations. The results also act as a base for a future definition of specific and targeted procedures for the acoustic characterization of port noise sources.

Waste Water Management

In Austria approximately 70% of the population is connected to sewerage and to biological waste water treatment plants. Whereas the urban areas are already provided with these facilities to a very high extent, effort is still needed in rural areas to meet the requirements of the Austrian legislation. The way, this task should be solved has provoked much controversy. It is mainly the question, whether centralised or decentralised sewage disposal systems are preferable from the ecological and economical point of view, that became a political issue during the last 5 years. The Institute for Water Quality and Waste Management was asked to elaborate a waste water management concept for the Lainsitz River Basin, a mainly rural area in the north of Austria discharging to the Elbe river. Both ecological and economical aspects should be considered. This paper presents the methodology that was applied and the criteria which were decisive for the selection of the final solution.

Abstract Advertising helps to establish a set of assumptions that the consumer will bring to all other aspects of their engagement with a given brand. Advertising provides tangible evidence of the financial credibility and competitive presence of an organization. Persuasion is becoming more important in advertising. In marketing, persuasive advertising acts to establish wants/motivations and beliefs/attitudes by helping to formulate a conception of the brand as being one which people like those in the target audience would or should prefer. Considering the changes in lifestyle and eating habits of a significant part of the population in urban areas in Romania, the paper aims to analyse how brands manage to differentiate themselves from competitors, to reposition themselves on the market and influence consumers, meeting their increasingly varied needs. Food brands on the Romanian market are trying, lately, to identify new methods of differentiation and new benefits for their buyers. Given that more and more consumers are becoming increasingly concerned about what they eat and the products’ health effects, brands struggle to highlight the fact that their products offer real benefits for the body. The advertisements have become more diversified and underline the positive effects, from the health and well - being point of view, that those foods offer (no additives and preservatives, use of natural ingredients, various vitamins and minerals or the fact that they are dietary). Advertising messages’ diversification is obvious on the Romanian market, in the context of an increasing concern of the population for the growing level of information of some major consumer segments.

Abstract The city of Granada is experimenting a big urban transformation, attending national and international commitments on clean air, energy efficiency and savings linked to greenhouse gases reduction strategies and sustainable development action plans. This situation constitutes a good scenario for new noise control approaches that take into account the sound variable and citizens empowering in urban design, such as the soundscape assessment of urban territory. In this way, soundscape tools have been used in Granada as a complementary method for environmental noise characterisation where traditional noise control techniques are difficult to be carried out or give limited results. After 2016 strategic noise map and in the preparation of the new noise action plan, the city came across a great acoustic challenge in a new area located outskirts characterised by growing urbanisation, still under development, the greatest legal protection because of sensitive teaching and hospital buildings and the greatest noise exposure from nearby ring-way supporting heavy traffic flow. As quiet urban areas are not characterised by the absence of noise but for the presence of the right noise, this research intended to provide the local administration with results and proposals to transform this conflict area in a pleasant or quiet urban place. Main results came from important and significative differences in morning and evening characterisation, as great differences appear in soundscape assessment over the day and along the soundwalk path, indicating the importance of time and local issues to adequately characterised citizens perception to be considered by administration in the development of strategies and effective noise control actions.

PurposeSeen from the seller's point of view, this study examines economic and non-economic satisfaction as distinct conceptual variables, and tests how the constructs relate to each other and to the business transactional cost variables of formalisation, specific investments and dependence.Design/methodology/approachData was collected from 213 key informants from Norwegian companies involved in business-to-business marketing. Structural equation modelling was used to test the posited hypotheses.FindingsThe findings show that sellers' economic satisfaction exerts a positive influence on non-economic satisfaction and on formalisation, while its posited influence on specific investments was not found to be significant. Formalisation was, however, not significantly influenced by seller non-economic satisfaction. Specific investment was positively influenced by seller non-economic satisfaction. The influence of formalisation on specific investments and dependence was significant. Specific investments were also found to be positively influenced by dependence.Research limitations/implicationsThe study reveals the importance of assessing both economic and non-economic satisfaction in trying to understand sellers' behaviour in business-to-business markets.Practical implicationsThe findings show the need for managers to ensure economic satisfaction, as its affects non-economic satisfaction.Originality/valueThis study contributes to a better understanding of satisfaction in business-to-business exchange relationships and its relationship with transactional cost constructs based on a seller's perspective.

<p>More than 25 years have passed since the definition of Active Tectonics as "tectonic movements that are expected to occur within a future time span of concern to society", formulated in a milestone book by the National Research Council on this topic (Studies in Geophysics, Active Tectonics, National Academy Press, Washington, D.C. 1986), and those words have still to be considered the most suitable and exhaustive way to explain this branch of the Earth Sciences. Indeed only bridging together basic studies ("tectonic movements"), rates of occurrence ("time span") and hazard assessment ("society") can we fully evaluate ongoing tectonic activity and its associated hazards. The broad Mediterranean Sea region is a paradigmatic area from this point of view, as on one hand this region displays in a relatively limited geographic extent a great variety of tectonic processes such as plate collision, subduction, volcanic activity, large-magnitude earthquakes, active folding and faulting, vertical uplift and/or subsidence. On the other hand, all the above mentioned tectonic processes can potentially affect a total population of about 450 million, mostly concentrated in fast-growing urban areas and/or close to industrial compounds and critical facilities often located nearby hazard sources.

Abstract Green concepts are important things to apply on buildings. The application of the green concept on mixed-use buildings must consider several criteria, one of which is the comfort aspect. The density of commercial buildings in Medan City causes a reduction in green open space, and even many buildings do not comply with the minimum green open space requirements on their buildings, which can support the development of this city to reduce environmental temperatures. The aim of this study is to analyze the green concept that can be applied to mixed-use buildings in urban areas. A mixed-use building design with the application of green building principles is the right choice to reduce the effects of climate. The green building concept can help reduce excess heat radiation inside and outside the building. The method used is qualitative with data collection techniques through observation. The analysis was carried out descriptively to obtain a mixed-use building model with the green building concept. The results show that land use efficiency, energy conservation, materials and water conservation can be applied to provide comfortable on buildings.

Using the first ever available information in Census of India 2011, covering 640 sub-national units (districts) in India, we analyze the correlates of modes of transport used by non-agricultural workers at the regional level covering both rural and urban areas. Providing a holistic picture from the perspective policy and academic perspective, we bring out some key stylized facts. Further, using the Seemingly Unrelated Regression (SUR) estimation, we model the transport mode choice for commuting by the workers in the context of rural and urban India, and further extend it based on distinction in motorized and non-motorized transport modes. We find that urbanization level, population size and density along with education attainment and worker’s sex ratio (gender ratio among workers), age (elderly) and land use mix play very important role in regional pattern in transport mode choice for commuting. These results highlight the dire need for proper development of transport infrastructure and understanding its various dimensions from socio-economic, demographic and spatial point of view in the context of developing countries.
