The selection of species which show the highest possible tolerance to negative habitat conditions, also among plants of foreign origin, is a pressing issue. One of the species we would like to recommend for planting in urban areas is the white mulberry species (Morus alba) due to both its outstanding adaptability and its ecosystem services. There are no reliable studies on the distribution of this species in urbanized areas in Poland, nor sufficient analyses of the methods of its renewal, both deliberate and spontaneous spread through self-seeding. Collecting data on the population of an alien species within individual regions and forecasting potential changes in the population’s size and structure, as well as its possible impacts on other organisms, is one of the basic measures to reduce biological invasions, which is one of the six priority objectives of the European Biodiversity Strategy and an element of the Strategy on Invasive Alien Species. The aim of this study was to determine the size and structure of the white mulberry population in the city of Wrocław and to analyse the relationship between this structure and intensity of anthropopressure and thermal conditions.

Public spaces are designed and managed in many different ways. In Hanoi, after the Doi moi policy in 1986, the transfer of the public spaces creation at the neighborhood-level to the private sector has prospered na-ture of public and added a large amount of public space for the city, directly impacting on citizen's daily life, creating a new trend, new concept of public spaces. This article looks forward to understanding the public spaces-making and operating in KDTMs (Khu Do Thi Moi - new urban areas) in Hanoi to answer the question of whether ‘socialization’/privatization of these public spaces will put an end to the urban public or the new means of public-making trend. Based on the comparison and literature review of studies in the world on public spaces privatization with domestic studies to see the differences in the Vietnamese context leading to differences in definitions and roles and the concept of public spaces in KDTMs of Hanoi. Through adducing and analyzing practical cases, the article also mentions the trends, the issues, the ways and the technologies of public-making and public-spaces-making in KDTMs of Hanoi. Win/loss and the relationship of the three most important influential actors in this process (municipality, KDTM owners, inhabitants/citizens) is also considered to reconceptualize the public spaces of KDTMs in Hanoi.

"The City of Oslo in Jan Erik Vold’s Poems. The aim of this paper is to examine, from a cultural and social perspective, the Norwegian urban areas and everyday situations in Jan Erik Vold’s (b. 1939) poems. Our close-reading technique reveals important social aspects, different places and streets, located in the capital city of Norway, Oslo. These urban poems written by the contemporary Norwegian poet Jan Erik Vold contribute to the reconstruction of a new Norwegian cultural identity as it is reflected in a selection of poems taken from Mor Godhjertas glade versjon. Ja (Mother Goodhearted’s Happy Version. Yes, 1968), followed by the poet’s wanderings in the city of Oslo in En som het Abel Ek (One Named Abel Ek, 1988), and concluding with his bitter social criticism in Elg (Moose, 1989) and IKKE. Skillingstrykk fra nittitallet (Not: Broadsides from the Nineties, 1993). Vold’s urban poems emphasise the transition from nyenkle (new simple), friendly and descriptive poems which present closely the city of Oslo on foot, to short, political and social critical poems from the 90s. Thus, it is of great importance to traverse various urban ‘landscapes’ in different periods of time, beginning with the 1960s, followed by the 80s and the 90s. Keywords: Jan Erik Vold, urban poems, social criticism, Norwegian urban areas, the city of Oslo "

Surface materials that turn into hard surface material and lack of vegetations are some of the effects of rapid development that can affect the micro climate in urban areas. This happened on Cik Ditiro corridor in the city of Yogyakarta which had quite dense activities, this was marked by various functions of land use and human activities throughout the day. The method is simulation method that uses the EnviMET 4.0 software and the empirical measurements. This method is to simulate the value of each climate variable in existing conditions and ideal conditions. The results of this research show that the condition of the Cik Ditiro corridor still belongs to the heat which is uncomfortable thermal conditions. Recommendations result of this research is to make better thermal comfort on corridor. The result of this research to give recommendations in terms of improving better for thermal comfort.

Abstract Urban areas are complex, vulnerable and continuously evolving, with interacting strategic services, assets and stakeholders. Potential effects of climate dynamics on urban areas may include the aggravation of current conditions, with identification of new hazards or risk drivers. These challenges require an integrated and forward-looking approach to sustainable urban development. Several tools and frameworks for assessing resilience have already been developed in different fields of study. However, aiming to focus on climate change, urban services and infrastructure, some specific needs were identified. In this light, a resilience assessment framework was developed to direct and facilitate an objective-driven resilience diagnosis of urban cities and services; to support decisions on selection of resilience measures and development of strategies to enhance resilience to climate change; to outline a path to co-build resilience action plans; and to track the progress of resilience in the city or in the service over time. The paper presents an outline of the structure of the framework and details the approach used in its development, including engagement tools and actions undertaken to assure stakeholder involvement in its development, validation and testing.

This paper seeks to provide a conceptual framework in which to examine the social practices of contemporary austerity programmes in urban areas, including how these relate to different conceptions of crisis. Of current theoretical interest is the apparent ease with which these austerity measures have been accepted by urban governing agents. In order to advance these understandings we follow the recent post-structuralist discourse theory ‘logics’ approach of Glynos and Howarth (2007), focusing on the relationship between hegemony, political and social logics, and the subject whose identificatory practices are key to understanding the form, nature and stability of discursive settlements. In such thinking it is not only the formation of discourses and the mobilisation of rhetoric that are of interest, but also the manner in which the subjects of austerity identify with these. Through such an approach we examine the case of the regeneration/economic development and planning policy area in the city government of Birmingham (UK). In conclusion, we argue that the logics approach is a useful framework through which to examine how austerity has been uncontested in a city government, and the dynamics of acquiescence in relation to broader hegemonic discursive formations.

This research sheds light on the relationship between the presence of location-based social network (LBSN) data and other economic and demographic variables in the city of Valencia (Spain). For that purpose, a comparison is made between location patterns of geolocated data from various social networks (i.e., Google Places, Foursquare, Twitter, Airbnb and Idealista) and statistical information such as land value, average gross income, and population distribution by age range. The main findings show that there is no direct relationship between land value or age of registered population and the amount of social network data generated in a given area. However, a noteworthy coincidence was observed between Google Places data-clustering patterns, which represent the offer of economic activities, and the spatial concentration of the other LBSNs analyzed, suggesting that data from these sources are mostly generated in areas with a high density of economic activities.

Introduction: The prevalence of dental caries among children has increased in the past decades. Dental caries has a multifactorial aetiology, including host (saliva and teeth), microbiology (plaque), substrate (diet), and time. The role of fermentable carbohydrates intake as a risk factor in the initiation and progression of dental caries. The purpose of this study was to determine the relationship between dental caries and carbohydrates intake among preschool-aged children in rural and urban areas of the city of Cimahi, Indonesia. Methods: The method used was an analytical cross-sectional study with pathfinder survey based on the WHO basic methods of oral health surveys. The data were collected through intraoral examination, and nutritional status measurement was done by using food frequency questionnaire. Statistical analysis used was the chi-square test. Results: From the study towards 100 preschool children resulted the prevalence of dental caries in rural and urban area respectively was 96 and 92%. The average value of deft index in urban area was 8.46 (95% CI:7.00-9.91) and was 7.98 (95% CI:6.50-9.45) in rural area. The average value of sucrose intake frequency in urban area was 237.14 (95% CI:204.95-269.32), whilst in rural area was 177.54 (95% CI:155.66-199.41). Conclusion: There was a relationship between dental caries and carbohydrates intake among preschool-aged children in the rural and urban area of the city of Cimahi, Indonesia.

The environment and its current components play an essential role in human learning. There is an interactive and mutual relationship between humans and environment. The relationship which is established between the container and the object in urban areas can be a type of learning and learner. The environment brings us together and disperses. People learn in it, become cultured, think, learn, organize themselves, and consolidate. The aim of this study is to explain the concept of learning space in the city as a place of learning through providing theoretical foundations.  The method is used in this study is a qualitative-descriptive method by using theoretical issues in learning and human-environment relationship under discussion in educational and environmental psychology. The finding demonstrated that in urban learning environments, the real needs of human beings are redefined and also they are designed and adopted to learning needs.

This article analyses a selection of pop music videos released between 2012 and 2014 that rescript Berlin’s Zeitlichkeit (temporality), the relationship between city spaces, history, and time. Examples include videos by German and non-German artists, ranging from David Bowie to Miss Platnum, Lilly Wood & the Prick, Alanis Morissette and Andreas Bourani. Striking synergies between the different sound-image-texts emerge around questions of historic memory, time, and time passing. Close analyses show how these Berlin music videos released between 2012 and 2014 challenge linear narratives of pasts and progress. In the non-linear conceptions of time suggested in these videos and songs, new and old agents can coexist and create images and narratives of a different temporal tapestry of the city.
