Advances in high density extracellular electrophysiology recording probes, such as Neuropixels, provide a promising avenue to accomplish this goal. Identifying the same neurons in multiple recordings is, however, complicated by non-rigid movement of the tissue relative to the recording sites (drift) and loss of signal from some neurons. Here we propose a neuron tracking method that can identify the same cells independent of firing statistics, that are used by most existing methods. Our method is based on between-day non-rigid alignment of spike sorted clusters. We verified the same cell identity in mice using measured visual receptive fields. This method succeeds on datasets separated from one to 47 days, with an 84% average recovery rate.</p>","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10802241/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87338500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through its high share of energy use and carbon emissions, the building sector is seen as central in this endeavor. While European Union (EU) and national regulation and incentive schemes provide an important context, how green building is realized often plays out at subnational spatial scales, including how green buildings are designed and embedded in existing regional and local (infra)structures. More localized scales can be especially important when considering the sustainability of buildings in operation. In contrast to the design and construction phases of green buildings, very little attention has been paid to post-occupancy studies and the practices of building users in enabling or constraining sustainability transitions. These actors are, however, crucial in reducing carbon emissions as a fabric-only or technologically-focused approach will be insufficient. This article seeks to contribute to a better understanding of the role of building users and the impact of green buildings once in operation through the frame of lived sustainabilities. It focuses on changes shaped by interdependences between discourses on green buildings including expectations, framings and understandings, activities as associated with living and working in buildings, as well as materialities of green buildings. Furthermore, we present a research agenda that highlights how wider everyday practices are affected by the entangled spatial dimensions of sustainability transitions which define different contexts and bring to the fore the role and importance of spatial scales in terms of the impact green buildings might have.","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"48 13","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using detailed population-wide register data for Sweden, we estimate how regional variation in housing prices and homeownership is associated with the individual’s decision whether to accept a job offer in the Stockholm metropolitan region and the interrelated choice between migration and commuting as the mobility mode. Our findings indicate that high relative housing prices in the Stockholm area and homeownership are associated with decreasing total geographical labour mobility to the region. This is pronounced among the young and among highly skilled workers. The negative effects of high relative housing prices and homeownership on migration are partially but not fully compensated by positive effects on commuting to Stockholm.","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"329 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139212018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, scholars have yet to link informal housing and the socio-historical regulations that gave rise to the birth of urban planning at the beginning of the 20th century. This article draws on archival and historiographical research to discuss the juridical construction of informal urbanisation in two capital cities at the core of the world-system, Paris and Madrid. In both cities, shantytowns were legally developed from at least the 19th century. However, such spatial production was outlawed (without addressing the root causes) from the first decades of the 20th century. Thus, precarious housing became informal housing as we know it today, giving rise to comparable but differentiated patterns of legal and extra-legal shacks construction, commercialisation and control (much like those generally associated with the global south). This article traces the long-durée and transnational nature of the informalisation of self-produced housing during the first half of the 20th century. Housing tenure conditions and shelter rights were weakened not only in Europe but also in other areas under its political and cultural influence. European urban policies, developed during the first half of the 20th century, may have induced dynamics of informal spatial production at a global scale.","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"325 ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139240213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Populist support tends to be concentrated in areas ‘left behind’ or ‘that don’t matter’, but we still lack an accurate understanding of (1) the locations of these places within major cities and (2) what characteristics of urban contexts prompt the populist vote. We aim to bridge this gap by analysing precinct-level electoral results of populist parties within six major Italian cities over the 2013–2022 decade. Through novel maps of the within-city populist vote, we identify four types of urban environments: populist strongholds, emerging populist, sporadically populist and never-populist areas. We then investigate how two types of intra-urban factors – compositional and contextual – relate to the formation of populist strongholds and support for populist parties with distinct ideological profiles. The findings improve our comprehension of the urban ‘places of populism’ and highlight the need for the ‘left behind’ thesis to focus more fully on within-city patterns and divides.","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"9 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139238641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But how effective can ephemeral micro-interventions be in achieving comprehensive structural change? This question is particularly relevant for non-technological experiments that are typically more place-bound than their technology-oriented counterparts. We argue that non-technological experiments may very well be impactful endeavors, but that knowledge and reflexivity about their contexts are key capacities for realizing their potential. Based on the literature, we define three context dimensions: structural conditions, political-institutional embedding, and imagined eco-social futures. By empirically delving into Graetzlmarie, an impactful governance experiment in Vienna, we show how “navigating context” in all the three dimensions has been a key capacity for the experiment’s success. It enabled adapting practices, self-conceptions, and objectives to specific but varying contexts, herewith ensuring the experiment’s impactful realization. Given the uneven distribution of such knowledge among actors in transformation processes, we discuss what this implies for experimentation. We argue for coordinating actors that serve as knowledge brokers and intermediaries between institutionalized policy and planning and ephemeral micro-interventions to achieve eco-social transformation.","PeriodicalId":47746,"journal":{"name":"European Urban and Regional Studies","volume":"17 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139241252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
