Arch bridges are one of the popular, oldest and graceful bridges which are being built in zones of the city and out of the city. However arches becomes especially sensitive to their buckling response due to dominated compressive force in the arch. In order to ensure stability conditions of the individual arch and arch bridges, it is estimated not just geometrical factor of arch, residual stress, work conditions, geometric imperfections but geometrical nonlinearity too. Geometric nonlinearity especially dominates in many times static indeterminable systems such as network arch bridges. However there are a few represents of estimation of geometric nonlinearity of the new construction form of the arch bridges created in a middle of 20th century. This paper represents estimation of geometric nonlinearity with numerical method of the steel arch bridges with vertical hangers and network arch bridges. There are determined stress-strain law and principal behavior of the steel network arch bridges under symmetric and asymmetric pedestrian loadings. Arkiniai tiltai – vieni populiariausių, seniausių ir grakščiausių tiltų, statomų miesto ir užmiesčio zonose. Tačiau dėl dominuojančios ašinės gniuždymo jėgos arkos tampa ypač jautrios stabilumo praradimui. Siekiant užtikrinti pavienių arkų ir arkinių tiltų pastovumo sąlygas, vertinami ne tik arkos geometriniai rodikliai, darbo stadijos, pradiniai įtempiai, geometriniai netobulumai, bet ir netiesinė konstrukcijos elgsena. Geometrinis netiesiškumas ypač dominuoja daug kartų statiškai neišsprendžiamose sistemose, tokiose kaip tinkliniai arkiniai tiltai. Tačiau šios XX a. viduryje atsiradusios naujos arkinių tiltų konstrukcinės formos geometrinio netiesiškumo vertinimas pateiktas minimaliai. Straipsnyje pateikiamas plieninių arkinių tiltų su vertikaliomis pakabomis ir tinklinių arkinių tiltų geometrinio netiesiškumo vertinimas skaitiniais metodais. Nustatomas plieninių tinklinių arkinių tiltų įtempių-deformacijų būvis ir esminiai elgsenos ypatumai, veikiant simetrine ir asimetrine pėsčiųjų apkrovomis.

Objective – High voluntary turnover rate has become the focus of most employers and scholars in related fields. Although employers have attempted to use a variety of retention strategies to retain qualified and skilled employees, the turnover rate remains high in the vast majority of industries around the world. Methodology/Technique – Past studies are concerned mostly with employees’ external demands such as salaries, fringe benefits, work conditions and less focus has been given on the importance of employees’ internal needs based on psychological capital. Therefore, there is a need to perform a study on the turnover from this perspective as it is crucial not only to retain the individual but also to ensure their contentment and satisfaction are fulfilled by their organizations. Findings – This paper undertakes a review of existing literature which specifically addresses the perspectives of individual psychology, and simultaneously explains the relationship between the two psychological factors (namely psychological capital and person-environment fit) and the turnover intention with the mediating effect of job satisfaction. Novelty – The arguments are presented to emphasize the needs to carry out this study. Type of Paper: Review.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

Practice Fields

Over the past decades, ‘participation’ has evolved as a key concept in a multitude of practice fields and discursive arenas, ranging from diverse political and economic contexts, through academic research, education and social work, urban planning and design, to arts institutions and artistic projects. While participation originally is a political concept and practice, it has long set out as a ‘travelling concept’ (Bal 2002). This special issue focuses on its travels between three fields of practice: the city, the arts and qualitative empirical research. Each of these practice fields over the past decades has yielded distinct understandings, objectives and methods in respect to participations, yet they also increasingly intersect, overlap and fuse with each other within specific practice contexts. What is more, many of the individual actors engaging in these initiatives on behalf of the city – from temporary projects to long-term collaborations – are not situated in one practice field only. Along with Jana König and Elisabeth Scheffel we understand them as ‘double agents’ (König and Scheffel 2013: 272–3) or even ‘multiple agents’, with simultaneous entanglements and commitments in more than one practice field.

SummaryA British team has been working since 1978 upon a programme of documentation and analysis in the Insula of the Menander at Pompeii, one of the irregular city-blocks situated immediately to the west of the old part of the city in an area which was developed from the early fourth century B.C onwards. Study of the structural techniques, of wall-abutments, and of anomalies in plan can be used in conjunction with the evidence of painted wall-plaster to identify five main phases in the building-history: Phase I (fourth-third centuries B.C), Phase 2 (second and early first centuries B.C), Phase 3 (c. 80-c. 15 B.C), Phase 4 (c. 15 B.C.-C. A.D. 50), Phase 5 (c. A.D. 50-79). These illustrate a complex pattern of changing property-boundaries, but underline the general trend towards increasing commercialization and greater pressure upon living-space in this area of the city. There is also interesting evidence of the economic basis of life in the individual houses during the years immediately before 79.

The subject of research in this paper is the planning of urban mobility development in the narrow part of Sarajevo using a model based on the growth matrix. The hypothesis of this research is: Based on the analysis of supply and demand of the city traffic system, good practices in sustainable urban mobility and existing strategies and development plans, a model for managing the whole planning process of sustainable urban mobility of the city traffic system in Sarajevo by 2026 can be proposed.In accordance with the experience of Europe’s main urban mobility observatory (Eltis) and sustainable urban mobility plans (SUMPs), the key elements are defined. The next step, after defining the elements of urban mobility, is to carry out the quantification of elements for 2016. Thereafter, there is a concise explanation of the growth matrix and model of managing the urban mobility planning process is created. In the research results, direct and indirect growth rates were elaborated and analyzed, i.e. the individual and synergic effects of the model. Finally, the synthesis of the research results was presented.

This study deals with the synthesis of selected attributes of public transport accessibility. The aim is to present a new method of multi-criteria analysis. As the research area, the city of Cracow has been chosen. The GTFS (General Transit Feed Specification) system has been used to obtain traffic data for buses and trams within the city‘s transport company (MPK Krakow). The analysis itself consists of 4 main accessibility indicators (walking time to each stop, number of lines, directions, and connections from each stop). The problem of exceeding the stops accessibility beyond the administrative border of Cracow has been solved by using a 500 m wide buffer zone around the city. To connect the individual layers of indicators into a multicriteria analysis, the Voronoi diagram function has been applied. The results of the method are presented in the form of synthetic maps of transport accessibility for each bus and tram stop in Cracow. Together with the synthetic accessibility maps, an index of a stop importance has been created as well, which consists of the sum of the mean percentages from 3 indicators (number of lines, directions, connections). The synthetic method used and acquired detailed values not only for the city of Cracow as a whole, but also its individual parts make it possible to provide a comprehensive picture of accessibility by public transport. This multicriteria analysis can also be extended for a comparative study of selected cities.

Point Of Departure

Within recent years, art and urbanism have gradually moved closer to each other and come together around socially engaged, dialogical projects. Participation and the creation of urban publics are topics that often concern artists as well as urban planners and activists. Based on a record of this recent conjunction between art and urbanism, the article examines practices, fractures, and conflicts in the aftermath of the social turn. With a point of departure in the coalescing public programme of the Istanbul Biennial and Occupy Gezi at Taksim Square in 2013, the article questions the art of participation. What type of public is created in the participative art? And is an artistic social turn towards the city even possible beyond the art institution? The article concludes that precisely in the conflict between the two different rationales of art and urbanism a participatory, urban public can emerge; a public, however, which lie beyond the intention and rationales of the individual actor.

The review presents the literature data and, revealed by authors, the patterns of changes in the dynamics of the infant mortality rate and its structure over a long period (2005-2017) in St. Petersburg. This index is one of the lowest in the Russian Federation. There are analyzed changes in the individual components of the structure of the infant mortality rate, related both to objective and subjective factors. In the city of St. Petersburg there was shown a persistent decline in the infant mortality rate due to the implementation of federal and city programs, closely correlated with structural components. The authors believe the positive dynamics of structural components in St. Petersburg to indicate the organization of all types of specialized and high-tech medical care for newborns.

Abstract The paper presents the results of research on the content of mercury in snow samples with the use of isotachophoresis. Snow samples were collected in December 2017 as well as in January and February 2018. Samples were collected in Siedlce in places where the individual heating of houses, mainly by hard coal, was visible. The highest mean content of mercury amounting to 0.36 μg/dm3 of water was determined in the snow samples collected in January 2018 in the Żwirowa housing development, and the lowest – 0.25 μg/dm3 in two housing developments: Nowe Siedlce and Topolowa, also collected in January. The snow samples collected in the Żwirowa housing development were characterised by the highest contamination with mercury compared to all the other samples collected for the analysis. The research is a continuation of pollution monitoring in the town of Siedlce in connection with the European Union recommendations on environmental protection and the ‘clean air’ programme implemented in Poland.

Internal Connections

This essay concerns itself with perceptions of the urban sphere, with its manifestations in literature and life writing, and with the city as a place of strangeness and travel in various senses, including the ways in which it pertains to the individual world view. Cities are places of density and internal connections, but their gates also open out and connect with other places, and increasingly other cities. Following a discussion of the Icelandic links between Copenhagen and Reykjavík, and the slow emergence of the latter as a „literary capital“, the course is set for foreign cities, including Berlin and Paris in the company of Walter Benjamin, and the experience of getting lost with Franz Kafka in places that may be Prague and New York. In attempting to answer the question whether it is possible to become intimate with cities, we have recourse to city guides, life maps, a touring theatre – and the art of losing and finding.
