Two species of the genus Celtis L. are represented in the city of Sombor, of which the most numerous is Celtis occidentalis L., prevalent in parks and alleys, which became a symbol of the city, with its priceless social, economic and environmental value. Their present situation could be described as alarming. The paper presents the results of the analysis of morphological characteristics of leaves and fruits of common hackberry, investigated at the level of 15 test trees, in order to assess the genetic variability of the available gene pool in the tree alleys at Sombor area. Following parameters were analyzed: total leaf length, lamina width, petiole length, and lamina width at the left and right side from midrib, as well as drupe diameter and weight of 1000 fruits. The descriptive statistics, one-way analysis of variance, LSD test and cluster analysis were done. The largest leaves were recorded at trees 1, 5 and 11, and smallest at the trees 7, 9 and 13, wherein genotype 1 was distanced from the other test trees, on multiple characteristics. The highest average of drupes diameter were recorded at trees number 4, 12, and 3. The obtained results indicate a satisfactory degree of variability of the analyzed characteristics at the level of test trees, which provides a good basis for exploring and proper use of the genetic potential of this species, as well as for conservation of the available gene pool.

The Postponement

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.

The second afterword to the book by Kamran Asdar Ali returns us to the city, and to the lives of Karachi’s working women and working classes. He draws on women’s poems, diaries, and memoirs to capture some more ephemeral qualities of everyday living and dying. These contrast with the violent suppression of an underclass of trade unionists and labor activists by a coalition of the state, military courts and industrialists, since the fifties. Given the long, progressive erosion of peace in Karachi how, he asks, might we imagine a therapeutic process of social, economic and cultural healing? Through an image of citizens “at work” creating citywide networks and connections, we are offered finally some possibilities of dreaming. Namely, through increased understandings, not of conflict, but also of each other’s intimate everyday lives, the dream emerges of a new political space or public where even intractable disagreements can be managed through gestures of kindness, compromise, and fresh vocabularies of how to carry on and get by.

Since the advent of the second digital revolution, the exponential advancement of technology is shaping a world with new social, economic, political, technological, and legal circumstances. The consequential disruptions force governments and societies to seek ways for their cities to become more humane, ethical, inclusive, intelligent, and sustainable. In recent years, the concept of City-as-a-Platform was coined with the hope of providing an innovative approach for addressing the aforementioned disruptions. Today, this concept is rapidly gaining popularity, as more and more platform thinking applications become available to the city context—so-called platform urbanism. These platforms used for identifying and addressing various urbanization problems with the assistance of open data, participatory innovation opportunity, and collective knowledge. With these developments in mind, this study aims to tackle the question of “How can platform urbanism support local governance efforts in the development of smarter cities?” Through an integrative review of journal articles published during the last decade, the evolution of City-as-a-Platform was analyzed. The findings revealed the prospects and constraints for the realization of transformative and disruptive impacts on the government and society through the platform urbanism, along with disclosing the opportunities and challenges for smarter urban development governance with collective knowledge through platform urbanism.

AbstractThe sustainable urban redevelopment project to protect biodiversity was developed to regenerate the external spaces of an ancient rural farmhouse, Villa Framarino, in the regional Natural Park of Lama Balice, a shallow erosive furrow (lama) rich in biodiversity, between two suburbs of the city of Bari (Apulia, Italy) and close to the city airport. This work includes a complex system of activities aimed not only at a spatial revaluation, necessary to relaunch the urban image, but it is accompanied by interventions of a cultural, social, economic, environmental and landscape nature, aimed at increasing the quality of life, in compliance with the principles of sustainability and social participation. One of the means to revitalize a territory subject to redevelopment is the planning of events and activities of socio-cultural value that involve the population to revive the sense of belonging to the territory and the community and at the same time to protect the biodiversity of the urban park of the protected natural area.

In the contemporary economy the more and more greater role is played by state and local government institutions. Offices of public administration not only create law, but more and more often become initiators of the different type of investments undertaken on the ground of their jurisdiction. Often neighbouring administrative units begin to compete between themselves in gaining of investments and resources for the purpose of its own development. In the functionality of mentioned offices the greater role is performed by IT systems building the architecture of a given unit, clearly expressed among other things in the idea of intelligent city. Applied by offices of public administration IT systems are more often opened for suppliants creating e-government tools [1]. In this paper was presented the role of e-government tools in the business activation of the region on the basis of IT systems made available by Czestochowa Municipal Office. The review of potential directions of the e-government tools usage in different areas of social-economic life of the city will be presented

This paper uses a typological approach as a tool to establish an analytical framework from a physical perspective to understand ‘place‘ and to identify key spatial characteristics that could adapt to local needs to deliver socio-cultural sustainability. Six representative housing types with their spaces and uses that were introduced in a historic neighborhood in Beijing, China are selected as case studies. Their morphological characteristics at the building, open space and neighborhood scales are examined, and typological transformations among the cases in terms of the degree of spatial continuity are identified. The paper proposes an analytical framework consisting of fifteen indicators to assess socio-cultural sustainability at the different morphological scales (building, open space and block/neighborhood) of the residents of the six cases. The score of changes from its original design is brought into calculations of continuities of spatial characteristics, which present the transitions and transformations of morphological characteristics in relation to adaptation of local needs and uses. The analysis results show that the spatial characteristics were changed when political-socioeconomic ideologies changed, and local needs and uses were transformed to follow these mutations, and finally, the methods of use in different morphological scales mostly differed from historical norms. Although the continuities of spatial characteristics were significantly changed, they are positively and continually accommodating the transformations and transitions of local needs and uses. On the other hand, the invariant spatial characteristics are important, which last despite transformation of the city development and changing of political-social-economic ideologies, and could be maintained for future development to enhance sociocultural sustainability.

<p><em>Salvia multicaulis</em> is a widespread species of Lamiaceae family in Iran. There are many discussions about its infraspecific variations. Although some varieties were definite for this species in various parts of the world, no infraspecific taxon was reported in Iran and all samples of this species were named as S. multicaulis. In this study, morphological characteristics of S. multicaulis populations, naturally growing in Iran, was examined. Twenty-two traits were examined in 94 individuals of this species to<br />identify their phenotypic difference. Most of the investigated features were showing a high degree of variability, but it was highly pronounced for some characteristics such as basal leaf shape, basal leaf width, basal leaf length/ width ratio and basal petiole length. Significant positive/negative correlations were observed between some morphological variables. Furthermore, significant negative correlations were found between the eastern distribution of populations with basal leaf petiole length and basal leaf length/ width ratio. Based on the UPGMA cluster analysis, populations were divided into two main branches. The first branch contained four populations, while the second branch was bigger and clustered in two sub-branches. In one of them,<br />three populations and in another one the rest populations arranged in two groups. CA joined plot confirmed that each of studied populations or group of populations had distinct morphological trait(s), which were useful in identification of them. Our findings supported population no. 13 had unique morphological traits such as the largest bracts and basal leaf petiole, highest flower number of each inflorescence cycle, widest and largest calyx. The conservation of the highly diverse populations of<br />Iranian S. multicaulis is recommended.</p>

Autonomous Development

Currently, 1 in 6 people live in slums, or informal settlements in cities throughout the developing world. They are built illegally and are characterized by lack of proper sanitation, unsafe housing, and crowded living conditions. Despite their appearance, informal settlements are legitimate communities; they are vibrant, with sophisticated social, economic and cultural networks that support the livelihoods of residents who call them home. These communities give the urban poor a physical place within the city, giving them access to the opportunities and advantages that the current age of the 'global city' can offer to any willing participant. As architects who see the responsibility in choosing the informal settlement as a realm for engagement, this thesis proposes that any architectural intervention be mindful of the importance of the networks contained within the streets and buildings of the informal settlement. By preserving the built-fabric of the settlement, the architect legitimizes the settlement's density and scale, while ensuring the urban poor have a physical place in the city. They have managed to develop their own communities without any investment from outside forces, any intervention should only support that autonomous development. These structures, as well as the people and activities with them, are vital to the survival of residents of informal settlements.
