The aim of this paper is to define and measure the relevance of the criteria for the evaluation of the inflow of goods in city centers, in order to improve delivery activities within city centers. The development of the city center leads to the grouping of numerous business operators, which results in the increase of the quantity of goods entering the city center, causing additional traffic congestion, higher levels of noise and emissions of harmful gases. In the long term, this leads to major dissatisfaction with the quality of life among city residents. Therefore, the planning of goods delivery must be in line with the sustainable development of city logistics, while at the same time considering the interests of relevant stakeholders. However, in the existing literature the criteria for evaluating delivery flows have not been comprehensively identified or evaluated by the stakeholders of city centers. In order to fill the research gap, the authors have defined four groups of criteria: technical-technological, economic-financial, organizational and social criteria. To determine the relevance of these criteria, it was necessary to use the questionnaire method to collect data from the stakeholder groups defined by the literature review. Regarding the relevant stakeholders (carriers, delivery recipients, residents and urban policy makers), the results have pointed out that the technical-technological and organizational criteria groups are considered the most relevant by the stakeholders regarding the inflow of goods in city centers.

The City

A city is a complex system that never sleeps; it constantly changes, and its internal mobility (people, vehicles, goods, information, etc.) continues to accelerate and intensify. These changes and mobility vary in terms of the attributes of the city, such as space, time and cultural affiliation, which characterise to some extent how the city functions. Traditional urban studies have successfully modelled the ‘low-frequency city’ and have provided solutions such as urban planning and highway design for long-term urban development. Nevertheless, the existing urban studies and theories are insufficient to model the dynamics of a city’s intense mobility and rapid changes, so they cannot tackle short-term urban problems such as traffic congestion, real-time transport scheduling and resource management. The advent of information and communication technology and big data presents opportunities to model cities with unprecedented resolution. Since 2018, a paradigm shift from modelling the ‘low-frequency city’ to the so-called ‘high-frequency city’ has been introduced, but hardly any research investigated methods to estimate a city’s frequency. This work aims to propose a framework for the identification and analysis of indicators to model and better understand the concept of a high-frequency city in a systematic manner. The methodology for this work was based on a content analysis-based review, taking into account specific criteria to ensure the selection of indicator sets that are consistent with the concept of the frequency of cities. Twenty-two indicators in five groups were selected as indicators for a high-frequency city, and a framework was proposed to assess frequency at both the intra-city and inter-city levels. This work would serve as a pilot study to further illuminate the ways that urban policy and operations can be adjusted to improve the quality of city life in the context of a smart city.

This article is part of the special cluster titled Bukovina and Bukovinians after the Second World War: (Re)shaping and (re)thinking a region after genocide and ‘ethnic unmixing’, guest edited by Gaëlle Fisher and Maren Röger. This article explores ways in which Habsburg nostalgia has become an important factor in contemporary place-making strategies in the city of Chernivtsi, Western Ukraine. Through the analysis of diasporic homecomings, city center revitalization, and nationalist rhetoric surrounding the politics of monuments, I explore hybrid and diverse ways in which Habsburg nostalgia operates in a given setting. Rather than a static and homogenous form of place attachment, in Chernivtsi different cultural practices associated with Habsburg nostalgia coexist with each other and depending on the political context as well as the social position of the “nostalgic agents” manifest themselves differently. Drawing from my long-term ethnographic fieldwork, I argue that in order to fully understand individuals’ attachment to space, it is necessary to grasp both the subtle emotional ways in which the city is experienced by individuals as well as problematize the role of the built environment in the visualization of collective memory and emotions of particular groups. The focus on changing manifestations of the Habsburg nostalgia can bring then a better understanding of the range and scope of the city’s symbolic resources that might be mobilized for various purposes.

This article expands on current conceptualizations and applications of precarity by exploring the everyday socio-spatial complexities of migrant squatters living in informal hotels in the center of Buenos Aires, Argentina. Through ethnographic methods, this research investigates squatters’ practices of negotiating access to shared domestic spaces and resources, while experiencing long-term waiting for eviction from their home and potentially from the city center. Employing a cultural geographies approach, this work is concerned with understanding the ways in which precarity is routinely experienced in the micro-spaces of everyday life. Precarity is examined in its temporal and spatial manifestations, with particular emphasis on gendered experiences and home-making practices. Moving through daily spaces and routine situations, I document how precarity is embedded in the mundane tasks of the domestic, and as a result, unevenly impacts women whose traditional roles as mothers and caretakers mean that they are often at the fore of place-making practices and responsibilities.

Abstract. On 6 April 2009 an earthquake of magnitude 6.3 occurred in L'Aquila city, Italy. In the city center and surrounding villages many masonry and reinforced concrete (RC) buildings were heavily damaged or collapsed. After the earthquake, the inspection carried out in the region provided relevant results concerning the quality of the materials, method of construction and the performance of the structures. The region was initially inhabited in the 13th century and has many historic structures. The main structural materials are unreinforced masonry (URM) composed of rubble stone, brick, and hollow clay tile. Masonry units suffered the worst damage. Wood flooring systems and corrugated steel roofs are common in URM buildings. Moreover, unconfined gable walls, excessive wall thicknesses without connection with each other are among the most common deficiencies of poorly constructed masonry structures. These walls caused an increase in earthquake loads. The quality of the materials and the construction were not in accordance with the standards. On the other hand, several modern, non-ductile concrete frame buildings have collapsed. Poor concrete quality and poor reinforcement detailing caused damage in reinforced concrete structures. Furthermore, many structural deficiencies such as non-ductile detailing, strong beams-weak columns and were commonly observed. In this paper, reasons why the buildings were damaged in the 6 April 2009 earthquake in L'Aquila, Italy are given. Some suggestions are made to prevent such disasters in the future.

ABSTRACT Objective The aim of this study was to evaluate the models and plannings of metallic framework of removable partial prosthesis sent to dental laboratories in the city of Recife. Methods: The physical and technical conditions of plaster models were sent by the dentists to 4 dental laboratories. All models were examined, photographed and recorded on a form according to the research objective. Results: A total number of 235 models sent by dental surgeons were used to prepare the metallic structure, in which none of the models presented surveying nor the path of insertion. Out of the 235 models, 41 (17.44%) presented serious failures, such as positive and negative bubbles, broken dental elements, direct retainers and damaged edentulous areas. With respect to the planning, only 22 (9.35%) models were presented with the metallic framework planning, but in an unsatisfactory way. Regarding mouth preparation, no model presented a guide plane, and only 6.8% of models had rests seats, but incorrectly prepared. Conclusion: The models evaluated presented poor quality, lack of planning and no mouth preparation. This shows the need for dental surgeons to be aware of the appropriate prosthesis models and plannings in order to ensure a satisfactory and long-term rehabilitation of the patient, as well as preserving the remaining mouth structures.

Middle Class Blacks

This chapter looks at the ambitious reform agenda that black middle-class activist residents went on to mount in these outlying city neighbourhoods, encompassing housing upkeep, business revitalization, traffic safety, trash removal, and efforts to reduce liquor availability, juvenile delinquency, vice, and crime – all in an attempt to maintain what they considered an acceptable quality of life. Perhaps the most ambitious effort along these lines was a venture in which a group of African American investors purchased and renovated the Lee-Harvard Shopping Center, making it during its existence from 1972-1978 the “largest black-owned commercial complex in the nation.” Sometimes these reform efforts involved moralizing or exhibited an explicit class bias; upwardly mobile middle-class blacks did not always recognize that less well-off newcomers were motivated by similar concerns with liveability. In the end, however, their various attempts to take charge of their lives and communities contributed to the long-term vitality of these neighbourhoods and the city as a whole.

This article aims to advance the literature on policy mobility by decentring the primacy of mobility itself and focusing on understanding what cities do in order to ‘arrive at’ localized versions of urban policy in relation to globally circulating ideas around creativity. The paper explores the performance of a particular local ‘creative economy’ in terms of institutional and strategic adjustments, key drivers and individuals and events, and the role of long-term local, national and international influences on ‘creative cityness’. It does this through an analysis of cultural and creativity policy and local stakeholders in the cultural policy scene in Gdańsk, Poland, focusing on the local performative aspects of mobile policies and arguing the need to understand the formation of a ‘common local project’ as a form of intra-urban connectedness alongside inter-urban connectedness. The paper extends the range of contexts in which the ‘creative city’ has been analysed to include post-socialist, post-European Union accession Central and Eastern Europe, thus making an original contribution by studying these issues in the context of the complex multi-scalar relations between the city, national government and the supranational European Union and the ideological conflict between national authoritarian neoliberalism and urban and supranational scale (neo-)liberalism.

With the aggravation of the traffic congestion in the city, car owners will have to give up commuting with private cars and take the public transportation instead. The paper uses the replication dynamic mechanism to simulate the learning and adjustment mechanism of the automobile owners commuting mode selection. The evolutionary stable strategy is used to describe the long-term evolution of competition game trend. Finally we simulate equilibrium and stability of an evolution of the game under a payoff imbalance situation. The research shows that a certain proportion of car owners will choose public transit under the pressure of public transport development and heavy traffic, and the proportion will be closely related to the initial conditions and urban transportation development policy.
