The different stages of research on high climatic quality city are presented in this paper: acquisition of appropriate urban climate information, analysis of different urban climate features and selection of planning strategies (accordingly with the climate zone). Then, with the aid of a GIS, systematic guidelines for planning can be given. As a result, different types of benefits for city dwellers are to be expected (comfort, health, economic). Lisbon is presented as a case study. It is shown how the “translation” of the knowledge of Lisbon’s urban climate into simple guidelines for urban planning in order to mitigate the urban heat island, promote ventilation and increase air quality, was carried out. To this end, maps of the physical features of the city of Lisbon were drawn, synthesised into “urban homogeneous units” map. Climate guidelines are specified for each of the six groups of units (brought together according to urban morphology, topography and position in town.

Providing citizens with the ability to move around in an accessible way is a requirement for all cities today. However, modeling city infrastructures so that accessible routes can be computed is a challenge because it involves collecting information from multiple, large-scale and heterogeneous data sources. In this paper, we propose and validate the architecture of an information system that creates an accessibility data model for cities by ingesting data from different types of sources and provides an application that can be used by people with different abilities to compute accessible routes. The article describes the processes that allow building a network of pedestrian infrastructures from the OpenStreetMap information (i.e., sidewalks and pedestrian crossings), improving the network with information extracted obtained from mobile-sensed LiDAR data (i.e., ramps, steps, and pedestrian crossings), detecting obstacles using volunteered information collected from the hardware sensors of the mobile devices of the citizens (i.e., ramps and steps), and detecting accessibility problems with software sensors in social networks (i.e., Twitter). The information system is validated through its application in a case study in the city of Vigo (Spain).

This article aims to encourage the interdisciplinary study of ‘languaculture,’ an approach to language and culture in which ideology, linguistic and cultural forms, as well as praxis are studied in relation to one another. An integrated analysis of the selection of linguistic and cultural elements provides insight into how these choices arise from internalized norms and values, and how people position themselves toward received categories and hegemonic ideologies. An interdisciplinary approach will stimulate a rethinking of established concepts and methods of research. It will also lead to a mutual strengthening of linguistic, sociolinguistic, and anthropological research. This contribution focuses on Limburg and the linguistic political context of this Southern-Netherlands region where people are strongly aware of their linguistic distinctiveness. The argument of the paper is based on a case study of languaculture, viz. the carnivalesque song ‘Naar Talia’ (To Italy) by the Getske Boys from the city of Heerlen.

Square dancing is a popular music-related group physical exercise for health benefits in China mainly participated by mid-aged women and elderly people. This paper investigates the soundscape and enjoyment of the square dancing in urban streets through a case study in Lichuan, a county level city in southwest China, in December 2017. It examines the impact of gender, age, participation and places on perceptions of square dancing soundscape. Two sites along two main urban streets in the city were selected to conduct onsite investigations where residents spontaneously perform square dancing on a daily basis. Ethnographical observations were conducted to identify the social-physical features and sounds of both sites during the dance and without dance. Sound pressure measurements (LAeq and LAmax) were also conducted under the two conditions. An off-site survey was distributed through the local social media groups to understand residents’ everyday experiences and perceptions of square dancing in the city; 106 responses were received for the off-site survey. T-tests and Chi-squared tests were used for statistical analysis of the survey data. The results show gender does appear to be a factor influencing the regularity of participation in square dancing, with a bias towards more female participants. Participation frequency of square dance has an impact on the enjoyment of square dancing. There is no correlation between the dislike of watching square dancing, or dislike of the music and a desire to restrict locations for square dancing.

Abstract Today, Algeria is one of the developing countries that are engaging seriously into a new approach consisting of all kinds of combined risk assessments for better prevention them. Note that, this is a fairly important parameter, that is, the safety of people and property. However, the magnitude of the risk, of whatever nature, affects a variety of diversified aspects (Human, economic, technical and environmental). This study presented a case study, which is sometimes paradoxical, seeing that it is the result of the combination of all risk factors and specific factors related to them connected to a fragile urban environment: Hassi-Messaoud. It is well known that Hassi-Messaoud is one of the most important city for Algeria's economy; in which the demographic development is mainly known by incessant flows of immigrants, motivated essentially by job search. This arbitrary of population distribution exposes this city to a certain danger; especially as Hassi-Messaoud is in a zone subject to a probable risk expressed here by being characteristic of an oil zone. Thus, this article aimed to provide elements of risk assessment related to oil activity. This approach could conclude that, through a schematic scale, the different types and levels of exposure and vulnerability could be identified, that is, characteristics of the urban space in question.

Abstract Typical urban and rural temperature records are essential for the estimation and comparison of urban heat island effects in different regions, and the key issues are how to identify the typical urban and rural stations. This study tried to analyze the similarity of air temperature sequences by using dynamic time warping algorithm (DTW) to improve the selection of typical stations. We examined the similarity of temperature sequences of 20 stations in Beijing and validated by remote sensing, and the results indicated that DTW algorithm could identify the difference of temperature sequence, and clearly divide them into different groups according to their probability distribution information. The analysis for station pairs with high similarity could provide appropriate classification for typical urban stations (FT, SY, HD, TZ, CY, CP, MTG, BJ, SJS, DX, FS) and typical rural stations (ZT, SDZ, XYL) in Beijing. We also found that some traditional rural stations can’t represent temperature variation in rural surface because of their surrounding environments highly modified by urbanization process in last decades, and they may underestimate the urban climate effect by 1.24℃. DTW algorithm is simple in analysis and application for temperature sequences, and has good potentials in improving urban heat island estimation in regional or global scale by selecting more appropriate temperature records.

This paper focuses on urban planning strategies to adapt cities to the increasing rising of temperatures during summer heat waves. The main target is to investigate which configuration and distribution pattern of green spaces could effectively improve natural cooling of urban environments. Although the benefit that green areas give to natural cooling is well known, this kind of studies has hardly been carried out, especially at an urban scale where it is crucial to define quantities and density of green areas to address open spaces design. To reach this goal, a methodology based on the interpretation of the statistical correlation among temperature, urban parameters and green areas configurational indicators was implemented and applied to the case study of the Municipality of Naples, performing all the analysis in a GIS. Results provide guidelines to improve natural cooling in urban areas adopting the most effective configuration and distribution of green areas within a densely-built context.

The present paper investigates the characteristics and best construction strategies of smart cities around the world, as well as the determining factors of the satisfaction of the quality of life and the importance of the value of environmental sustainability. A case study of the city of Kalampaka and its residents was examined. The survey was conducted between July 2016 and August 2016. The selection of the sample was done by using the method of simple selection and includes a random sample of N=150 individuals. Statistical analysis showed that resident’s knowledge about smart cities was fairly good (48% of sample knew the phrase “smart cities”). Furthermore, they believe that the appearance of the city of Kalampaka needs improvement (75% of sample is disappointed with the current appearance of the city). Regression analysis showed that the value of environmental sustainability is greatly influenced by the energy saving, as well as, innovation has an impact on the level of quality of life. Older people seem to be satisfied with administration’s efforts.

Health being one of the most important aspects of life, people are much concerned about their health. Because people value their health, today cities are planned considering the health and environment for providing good quality of life. Many studies have shown different effects in health due to interaction with environment. As socioeconomic, environmental and cultural conditions may vary from place to place, people living in different areas in the cities can have different health outcomes. Also, people's perception of such neighborhood conditions can vary which can influence their health. There can be different resources in and around the neighborhood that provide opportunity for its people to perform different health-benefitting activities. Such physical features can be termed as health-related resources or in other words health opportunities. This study was conducted in two different type of neighborhoods in Dortmund, Nordstadt being deprived and Kreuzviertel being affluent. To know which locations people, consider as good or bad for their health, participants who agreed to take part in questionnaire survey were directly asked to point out the places they use and avoid for health-related activities. This study found out different types of health opportunities identified by respondents in Nordstadt and Kreuzviertel. Respondents from Nordstadt mentioned health opportunities inside and outside their neighborhood whereas in Kreuzviertel health opportunities were pointed outside the neighborhood. The information about people's perception on local neighborhood can be taken as useful insights for planners and decision-makers to plan development programs. The research provides an opportunity to formulate policies that address main problems acting as barriers so that people can get maximum benefits from health opportunities. To find out detailed explanations for differences between actual and perceived environmental situation, more in-depth research is needed.

Globally, the use of electric vehicles, and in particular the use of electric buses, has been increasing. The city of Nanjing leads China in the adoption of electric buses, supported by city policies and infrastructure. To lower costs and provide a better service, vehicle selection is crucial, however, existing selection methods are limited. Accordingly, Nanjing Bus Company developed a test method based on road tests to select a bus. This paper presents a detailed description of the test method and a case study of its application. The method included an organization structure, selection of eight test vehicles (four 10 m length, four 8 m length) from four brands (a total of 32 test vehicles), selection of indicators and selection of routes. Data was collected from repeated drives by 65 drivers over an 8-week period. Indicators included power consumption, charging duration, failure duration and driving distance. It is concluded that the road test method designed and conducted by the Nanjing Bus Company provides a good framework for the selection of pure electric buses. Furthermore, subsequent experience with selected buses supports the validity and value of the model.
