The processes of urban sprawl that have been present over the past two decades in the different strata of the urban hierarchy have also affected, as a whole, medium-sized cities. The urban sprawl has been particularly pronounced during the period of expansive Spanish urbanism, in which many of the municipalities situated in the vicinities of large cities have been affected by major demographic dynamics and (sub)urbanisation development outside the traditional city limits. Sometimes, these processes have been greater than the nearby cities in the urban area where they are inserted. In this study, we examine the general mechanisms identified within an urban crown size (within a radius of 30 km) and at the scale of the municipality, based on an analysis of two distinct periods: one linked to a strong growth dynamic (2000–2008), and another related to subsequent crisis (2009–2016). A group of 23 inner medium-sized Spanish cities has been analysed, taking into account the trends of the population, the surface of unbuilt plots, the built surface, and the amount of housing. We have identified the typologies of their respective urban areas over the two periods considered.

The spatiotemporal evolution of an impervious surface (IS) is significant for urban planning. In this paper, the IS was extracted and its spatiotemporal evolution for the Chengdu urban area was analyzed based on Landsat imagery. Our experimental results indicated that convolutional neural networks achieved the better performance with an overall accuracy of 98.32%, Kappa coefficient of 0.98, and Macro F1 of 98.28%, and the farmland was replaced by IS from 2001 to 2017, and the IS area (ISA) increased by 51.24 km2; that is, the growth rate was up to 13.8% in sixteen years. According to the landscape metrics, the IS expanded and agglomerated into large patches from small fragmented ones. In addition, the gross domestic product change of the secondary industry was similar to the change of ISA between 2001 and 2017. Thus, the spatiotemporal evolution of IS was associated with the economic development of the Chengdu urban area in the past sixteen years.

En este artículo se analiza la evolución reciente de la segregación socioespacial y la de la conformación urbana en la ciudad de Salvador, a la luz del debate sobre las transformaciones de las metrópolis dentro del capital globalizado. Si bien se reconoce que todas las grandes ciudades terminan siendo alcanzadas por la globalización, en el texto se resalta, sin embargo, que los efectos de ese proceso no son uniformes ni convergen en un modelo único de ciudad. Es necesario considerar la conformación histórica de cada una de ellas, sus instituciones, actores y decisiones políticas locales dentro de una dinámica definida por la continuidad/transformación, donde lo que ya existía condiciona la irrupción de lo nuevo, que en muchos casos ya había comenzado a delinearse en el pasado. Mediante la demostración de la conformación de una metrópoli extremadamente desigual y segregada y la medida en que las transformaciones han agravado tales alteraciones al paso de los últimos años, esta revisión del caso de Salvador se propone exponer algunas reflexiones para entender mejor los efectos del proceso de globalización sobre las grandes ciudades de América Latina. AbstractThis article analyzes the recent evolution of the socio-spatial segregation and urban configuration of the city of Salvador, in light of the debate on the transformations of metropolises within globalized capital. Although it is a well-known fact that large cities end up being absorbed by globalization, the text stresses the fact that the effects of this process are not uniform nor do they converge in a single model of a city. It is essential to  consider the historical moment of each of them, their institutions, actors and local political decisions within a dynamic defined by continuity/transformation, in which what already existed conditions the emergence of what is new, which in many cases, had already begun to be shaped in the past. Through the demonstration of the configuration of an extremely unequal, segregated metropolis, and the extent to which the transformations have aggravated these alterations over the years, this review of the case of Salvador proposes offering some reflections to provide a better understanding of the effects of globalization on major Latin American cities.

Purpose In the past months, the authors have experienced an exceptional global situation that especially affects the most vulnerable population. This paper aims to analyse the needs, strengths and good practices of the organisations that have continued to study with the migrant population during the health crisis. The main objective was to determine how the health, social and communication crisis has affected the management of the organisation itself, the communications with its direct beneficiaries, the communications with the rest of society, as well as the perception that organisations specialised in migration have about how media has communicated the information of COVID-19 and migrant population. Design/methodology/approach The authors have circulated a questionnaire with open questions that covered the four dimensions previously mentioned. Findings The results show the analysis of the answers of 11 of the most important national and international organisations in the field of migration and refuge that operate in Spain. Originality/value Key issues have emerged related not only to the principal management concerns, internal digital communication, the adaptability of external communication and the major effort required to provide information about migration but also to innovative good practices. That other third sector organisations focussed on migration will be able to apply in the future and in other geographic areas.

Studying urban expansion from a longer-term perspective is of great significance to obtain an in-depth understanding of the process of urbanization. Remote sensing data are mostly selected to investigate the long-term expansion of cities. In this study, we selected the world-class urban agglomeration of Beijing-Tianjin-Hebei (BTH) as the study area, and then discussed how to make full use of multi-source, multi-category, and multi-temporal spatial data (old maps and remote sensing images) to study long-term urbanization. Through this study, we addressed three questions: (1) How much has the urban area in BTH expanded in the past 100 years? (2) How did the urban area expand in the past century? (3) What factors or important historical events have changed the development of cities with different functions? By comprehensively using urban spatial data, such as old maps and remote sensing images, geo-referencing them, and extracting built-up area information, a long-term series of urban built-up areas in the BTH region can be obtained. Results show the following: (1) There was clear evidence of dramatic urban expansion in this area, and the total built-up area had increased by 55.585 times, from 126.181 km2 to 7013.832 km2. (2) Continuous outward expansion has always been the main trend, while the compactness of the built-up land within the city is constantly decreasing and the complexity of the city boundary is increasing. (3) Cities in BTH were mostly formed through the construction of city walls during the Ming and Qing dynasties, and the expansion process was mostly highly related to important political events, traffic development, and other factors. In summary, the BTH area, similarly to China and most regions of the world, has experienced rapid urbanization and the history of such ancient cities should be further preserved with the combined use of old maps.

‘Archive’ is a totality of records, layers and memories that are collected. A city is the archive that consists of the conscious selection of these layers and traces of the past and the present, looking towards the future. Metaxourgio is an area in the wider historic urban area of Keramikos in Athens that includes traces of various eras, beginning in the Antiquity and continuing all the way into the 21st century. Its archaeological space ‘Demosion Sema’ is mostly concealed under the ground level, waiting to be revealed. In this proposal, Metaxourgio is redesigned in light of archiving. Significant traces of the Antiquity, other ruins and buildings are studied, selected and incorporated in the new interventions. The area becomes the ‘open archive’ that leads towards its lost identity. The proposal aims not only to intensify the relationship of architecture with archaeology, but also to imbue the area’s identity with meanings that refer to the past, present and future.

Abstract. This paper describes the landslides and slope stability evaluation in the urban area of Kruja town, Albania. Kruja is a~historical and heritage center, due to the existence of many important cultural monuments including Skanderbeg castle and Bazaar square etc. The urban area of Kruja town has been affected from the Landslides effects, in the past and also present. From this phenomenon many engineering objects such as buildings, roads etc. are damaged and demolished. From the engineering geological mapping at scale 1 : 5000 it is observed that many active landslides have dramatically increased in activity after 1980s. The landslide types found in the studied area are earth slides, debris flow, as well as rock fall and rock rolling. Also, from field works and laboratory analysis, the slope stability of whole urban areas has been determined; for this purpose the studied zone is divided into the stable and unstable areas, which helps to better understand the mass movement's activity as one of the most harmful hazards of the geodynamics' phenomena.

Introduction: There has been increasing awareness of employment difficulties for physicians, especially surgeons, in Canada over the past few years. Our objective was to elucidate the attitudes and experiences of graduating Canadian urology residents in obtaining employment.Methods: We surveyed four separate cohorts of graduating urology residents in 2010, 2011, 2016, and 2017. Responses from the 2010 and 2011 cohorts were combined and compared to the combined results of the 2016 and 2017 cohorts. Mean Likert responses were compared using unpaired t-tests. An agreement score was created for those responding with “strongly agree” and “agree” on the Likert scale.Results: A total of 126 surveys were administered with a 100% response rate. The job market was rated as poor or very poor by 64.9% and 58.4% of graduates in 2010/2011 and 2016/2017, respectively (p=0.67). Lack of resources was identified as the biggest barrier to improved employment in both cohorts. Networking at meetings and staff urologists at their institution were the most important factors aiding employment identified by both cohorts. The ideal practice was academic or academically associated community practices in a large urban area, with 5‒10 partners for both cohorts.Conclusions: The majority of graduating urology residents viewed the job market as poor or very poor and this did not change over a six-year period. It is unclear how much personal preference for location and practice type drove the somewhat negative outlook of employment opportunities, as the majority of residents were seeking large urban, academic, or academically associated community practices in competitive locations.

Competing Goals in Formulating a Code of Conduct on Restrictive Business PracticesFor the past thirty years efforts to formulate and implement acceptable international norms to regulate restrictive business practices (R.B.P.’s) affecting international trade have largely failed. Yet, none can deny the necessity of such international norms in the face of the inability of national legal systems to cope with an economic order of international dimensions. The abortive International Trade Organization, as part of the Havana Charter of 1948, and the Draft E.C.O.S.O.C. International Agreement of 1953, which were originally initiated by the United States, were eventually rejected by it because “the various national policies, legislation, and enforcement procedures in this field were not sufficiently comparable.”
