During rush hours, commuters are exposed to high concentrations and peaks of traffic-related air pollutants. The aims of this study were therefore to extend the inhaled dose estimation outcomes from a previous work investigating the inhaled dose of a typical commuter in the city of Milan, Italy, and to extend these results to a wider population. The estimation of the dose of pollutants inhaled by commuters and deposited within the respiratory tract could be useful to help commuters in choosing the modes of transport with the lowest exposure and to increase their awareness regarding this topic. In addition, these results could provide useful information to policy makers, for the creation/improvement of a mobility that takes these results into account. The principal result outcomes from the first part of the project (case study on a typical commuter in the city of Milan) show that during the winter period, the maximum deposited mass values were estimated in the “Other” environments and in “Underground”. During the summer period, the maximum values were estimated in the “Other” and “Walking (high-traffic conditions)” environments. For both summer and winter, the lowest values were estimated in the “Car” and “Walking (low-traffic conditions)” environments. Regarding the second part of the study (the extension of the results to the general population of commuters in the city of Milan), the main results show that the period of permanence in a given micro-environment (ME) has an important influence on the inhaled dose, as well as the pulmonary ventilation rate. In addition to these results, it is of primary importance to report how the inhaled dose of pollutants can be strongly influenced by the time spent in a particular environment, as well as the subject’s pulmonary ventilation rate and pollutant exposure levels. For these reasons, the evaluation of these parameters (pulmonary ventilation rate and permanence time, in addition to the exposure concentration levels) for estimating the inhaled dose is of particular relevance.

Taking into account that accessibility is one of the most strategic and determining factors in economic models and that accessibility and tourism affect each other, we can say that the study and improvement of one of them involved the development of the other. Using network analysis, this study presents an algorithm for labeling the difficulty of the streets of a city using different accessibility parameters. We combine network structure and accessibility factors to explore the association between innovative behavior within the street network, and the relationships with the commercial activity in a city. Finally, we present a case study of the city of Avila, locating the most inaccessible areas of the city using centrality measures and analyzing the effects, in terms of accessibility, on the commerce and services of the city.

Surabaya, is one of the oldest cities in Indonesia. Since 1612, Surabaya has been a very busy trading center. Kalimas River, which is the river that flowing in the middle of the city of Surabaya, necessarily be a "River of Gold". It is used by traders, as a transport route for carrying goods from central Java to Surabaya. And from Surabaya, these goods are distributed throughout the world. The river management of Kalimas River is very complex. On the other hand, the development of tourism in Surabaya is very encouraging. Then, it is needed to propose a new tourism destination base on the potential of Kalimas River. Because there is no type of water attractions in Surabaya yet, so we need a study that focused on understanding the river lane as an alternative of water attraction in Surabaya. This research will be done in the realm of qualitative research. Based on the research objectives, the type of research that will be applied research so that the results can be much easier to implement. As the summary, it concluded that there are 4 steps to develop the Kalimas River lane as an aternative for water tourism destination in Surabaya, which are improving the quality of its existing condition, developing its potential to serve the purpose of water tourism, achieving the needs and expectations of the citizens of Surabaya on the river lane as an alternative water tourism destination, and finding new icon for Surabaya water tourism.

There have been two types of scholarly discussion on city branding. On the one hand, city branding has been conceptualised as a differentiation strategy of entrepreneurial cities involved in interspatial competition. On the other hand, researchers have recently emphasised the need to pay attention to increasingly pervasive and transformative forms of city branding, including branding as an urban policy and a form of planning. Drawing on a case study carried out in Helsinki, Finland, this article connects these two approaches by analysing Helsinki’s recent city branding endeavour in the context of the qualitative transformation of the entrepreneurial city. The article shows how city branding highlights and constitutes the city as an entrepreneurial platform and enabler bound up by the extended entrepreneurialisation of society.

This article identifies and compares the housing preferences of seniors and pre-senior citizens in Poland. In addition, the attitude of residents of large cities in the Wielkopolskie Voivodeship towards senior citizens’ housing was determined. Surveys were conducted in the two largest cities of this region. The influence of the potential behaviors of this group of society on the development of housing was also examined. Results showed that differentiation of housing preferences was visible primarily when choosing the type of development and size of the dwelling. Seniors preferred smaller units in multi-family housing construction. Pre-senior citizens, on the other hand, were more likely to think about living in a single-family house. The location of a new dwelling was also important. Seniors, more often than people aged 50–59, chose a location in the city center. Pre-senior citizens, in contrast, more often decided to live in a rural area or outside the city center. Moreover, the attitude of seniors towards senior citizens’ housing is undecided, which may indicate that many people may change their housing preferences in the future and decide to move.

The means of rail transport as well as other modes of transport primarily enable people to easily overcome certain distances over a period of time. This implies the need for it to be adapted to such specificities, together with other elements in places where high concentrations of passengers are exchanged. This paper deals with a common problem of accessibility of rail transport to people with reduced mobility (PRM). PRM refers to people whose mobility is reduced due to physical incapacity, an intellectual deficiency, age, illness or any other cause of disability when using transport. Therefore, a thorough analysis of accessibility of rail transport to this group of passengers will be conducted for the city of Zagreb according to certain indicators. The rail station is considered to be accessible if a PRM passenger can enter passenger terminal, consume services available there and if is able to get to the platform from where the train will depart. The rolling stock is accessible if a PRM passenger can buy a ticket, enter the train and have predicted and available space in the train. By determining the real state of accessibility to PRM passengers of all railway stations and used rolling stock in suburban rail transit in the city of Zagreb, measures will be proposed to increase accessibility to these passengers and thus facilitate their integration into society in this segment and increase their quality of life.

The Christchurch City Council election of 2013 provides a compelling case study through which to consider the interaction between politics and city space. On the one hand, through the careful placement of campaign posters, politics encroached on the physical terrain of the city. On the other hand, candidates included in their campaign material multitudinous references to ‘Christchurch the city,’ demonstrating the extent to which the physical environment of the post-disaster city had become central to local politics.

Abstract Aim: To present the work of professionals and volunteers of the local help network that revolves around trying to help the homeless and to stimulate readers to critically assess the possible methods aimed towards the successful integration of those people into society. Methods: In the city of Koper, we visited five governmental (GOs) and non-governmental organisations (NGOs): Red Cross Koper, Daybreak Association, Center for Social Work Koper, Diocesan Caritas Koper and Koper Prison; and interviewed 3-10 staff members at each organisation. Results: For each organisation, we described its duties and activities, including its interconnection with other organisations, methods of integrating the homeless into the society and the personal thoughts of its staff members. Conclusions: Both GOs and NGOs are necessary for providing effective assistance to people in need. NGOs excel at quickly responding to immediate needs. Their programs are usually implemented only as short-term resolutions. GOs on the other hand require a longer time to implement their concepts. Nonetheless, in contrast to NGO projects, they provide long-term stability. Even though people from remote parts of the society usually cooperate, the efforts of those who work with them are nothing short of exerting. They strive to achieve a general social acceptance of their ward population, which is the one thing those people need the most. Since only the society is truly capable of offering them a firm stepping stone towards escaping from the vicious circle in which they stray.

The medieval Armenian church of Famagusta, Cyprus, lying in the northwestern or Syrian quarter of the city (Fig. 1), provides a case study through which to raise issues concerning the historical conservation of Famagusta's cultural heritage.2 This article surveys aspects of the building's history, its conservation record, and proposes how it might play a role in any future plans to vitalize the historical centre of the city. The structure may, if utilized in concert with the other historical structures of Famagusta, function to contribute to the rejuvenation of this medieval walled town (Doratli et al. 2007:65-88).

The two fragmented mangrove forests, located in Graha Indah (HMGI) and Margomulyo (HMM) Balikpapan (East Kalimantan), are important habitats for Bekantan, an endemic and endangered animal species in Indonesian Borneo. The local government has put some conservation efforts by promoting those locations as the tourist destinations but they are not optimally well managed. This research aims to determine the visitors’ profiles, perceptions, and potential ticket funding by using questionnaires. Visitors’ ticket funding preference was obtained using the Willingness to Pay (WTP) method and analyzed using multiple regression analysis. Visitors’ profiles and perceptions were analyzed descriptively. The results showed that the visitors’ WTP in HMM and HMGI were Rp9.258 and Rp13.980, respectively, strongly influenced by income, type of jobs, and visiting frequency in HMGI. Meanwhile, HMM visitors were dominated by students (63%), with 11-20 years old by age (58%). On the other hand, the visitors’ occupation in HMGI was more varied i.e. private sectors (27%), students (27%) and civil servants (24%), with 21-30 years old by age (35%). Most of the visitors were from the city of Balikpapan that reached, 76% and 62% in HMM and HMGI, respectively. Potential funding from visitors cannot be estimated due to the lack of accurate data on the annual number of visitors. Internet and social media are potential methods to promote ecotourism in both places as well as promoting mangrove and bekantan conservation.
