The location of creative clusters in non-metropolitan areas: A methodological proposition

This article studies creative clusters outside metropolitan areas in Spain. Both the notion of cluster and that of creative activity tend to be associated by mainstream research with urban settings; thus, situating them in an non metropolitan or rural localities has required us to adapt the usual methodology to the scale and idiosyncrasies of a rural setting. Based on this new focus, we have been able to identify 761 municipalities that could host creative clusters within an initial area of study of 7367 non-metropolitan municipalities with fewer than 50,000 inhabitants. This methodology also has allowed us to measure intensity, internal composition, and localization, so that those of a more mature or advanced character, having a greater level of specialization and diversity, predominate in places close to metropolitan areas and the Mediterranean axis, whereas in the inner Spain, they are found in a lower proportion and in a more scattered and discontinuous manner. Activities belonging to the Functional Creations sector prevail over those from Communication and Patrimony in the configuration of the clusters, although there are differences in relative specialization according to their mature or advanced level. In addition, some of the most significant indicators of rural dynamism e population growth, human capital, unemployment, and economic activity e show much better behaviour in municipalities with creative clusters

Cultural dynamism and business vitality in medium-sized cities—evidence and proposals for sustainable development

This work uses tools recently designed to conduct analyses and proposals around the cultural development of medium-sized cities. The Cultural and Creative Cities Monitor model, or CCCM, is first applied to the 81 cities in Spain with between 50, 000 and 100, 000 inhabitants. We also refer to the UNESCO Culture/2030 Indicators, specifically indicator 8 (Cultural companies), to in-vestigate whether cultural dynamism is related to business vitality in those cities. Our observation of the 29 CCCM indicators and the C3 index, which synthesizes cultural performance, is explained, and these data are complemented with cultural business data (on assets, benefits, and jobs) from a sample of 13, 204 firms. The C3 index values reveal significant differences in the cultural and creative performance of the selected cities according to their location (metropolitan or non-metropolitan) and their administrative rank. Moreover, when comparing the C3 index with the indicators on business activity, evidence indicates a clear positive relationship between cultural dynamism and firm vitality. These results support the contribution of culture to the sustainable development of me-dium-sized Spanish cities and further establish the suitability of the tools used to assist cities in designing appropriate cultural policies

Cultural and creative ecosystems in medium-sized cities: Evolution in times of economic crisis and pandemic

This article seeks to forecast the short-and medium-term impacts of the coronavirus pandemic on the cultural and creative ecosystems of the 81 cities in Spain with between 50, 000 and 100, 000 inhabitants. Data on employment in nine sectors (per NACE Rev. 2) support the characterization of cultural ecosystems based on their dynamism, specialization, and propensity to form clusters (thanks to the co-location of certain sectors, meant to generate inter-sectoral spillovers and cross-sector synergies). The applied methodology consists of comparing these three attributes during and following the 2008 financial crisis. Then, any changes observed are interpreted in light of arguments from the COVID-19 literature, and from our own analysis, in order to assess the probability of recurrence (or nonrecurrence) during the current pandemic. Throughout this process, the metropolitan or non-metropolitan position of cities is taken into consideration. A first conclusion is that, as in the financial crisis, the behavior of ecosystems during the pandemic will be asymmetric. Secondly, metropolitan and non-metropolitan cities will maintain their distinctive sectoral specializations. Non-metropolitan cities appear to be more vulnerable for their strong connection to creative sectors most affected by the pandemic, although some can take advantage of good cultural supply and proximity to metropolitan centers. Metropolitan cities seem more secure, thanks to the higher presence of less vulnerable sectors (due to elevated and accelerating digitization). Nevertheless, most functional clusters were diminished during the financial crisis, and it seems unlikely that sectoral co-locations will re-emerge in a post-pandemic scenario as a business strategy, at least in the short term. Beyond these forecasts, we recommend dealing with certain structural failures of these ecosystems, especially the vulnerability and precariousness of most cultural and creative companies and workers

Geoelectrical and electromagnetic methods applied to paleolimnological studies: Two examples from desiccated lakes in the Basin of Mexico

Paleolimnological studies require a broad understanding of the geometry and depth of the sedimentary fill of lake basins prior to coring campaigns. Seismic methods are routinely employed for the indirect characterization of lake-bottom sediments. However, the use of seismic methods might occasionally be limited due to surface conditions or poor seismic contrasts between the stratigraphic units, which lead to data quality that is too poor to provide sufficient information for the selection of drill sites. Sources of cultural noise are one of the main reasons why seismic methods fail in study areas near or within large cities, such as Mexico City. Under certain conditions, electrical and electromagnetic methods might be a suitable substitute or complement to seismic exploration, as they respond to different physical properties of the subsurface. To evaluate the applicability of such methods, here we present two recent case studies from the desiccated lakes Chalco and Xochimilco both located in urban areas within the Basin of Mexico where electrical resistivity tomography (ERT), transient electromagnetic (TEM) and magnetotelluric (MT) soundings were conducted for the characterization of lake basement and lacustrine sediments. In both examples, the results of the geophysical exploration contributed valuable stratigraphic information for the following drilling and core recovery, which highlights the potential of electrical and electromagnetic methods in paleolimnological studies

Updating known distribution models for forecasting climate change impact on endangered species

To plan endangered species conservation and to design adequate management programmes, it is necessary to predict their distributional response to climate change, especially under the current situation of rapid change. However, these predictions are customarily done by relating de novo the distribution of the species with climatic conditions with no regard of previously available knowledge about the factors affecting the species distribution. We propose to take advantage of known species distribution models, but proceeding to update them with the variables yielded by climatic models before projecting them to the future. To exemplify our proposal, the availability of suitable habitat across Spain for the endangered Bonelli’s Eagle (Aquila fasciata) was modelled by updating a pre-existing model based on current climate and topography to a combination of different general circulation models and Special Report on Emissions Scenarios. Our results suggested that the main threat for this endangered species would not be climate change, since all forecasting models show that its distribution will be maintained and increased in mainland Spain for all the XXI century. We remark on the importance of linking conservation biology with distribution modelling by updating existing models, frequently available for endangered species, considering all the known factors conditioning the species’ distribution, instead of building new models that are based on climate change variables only.Ministerio de Ciencia e Innovación and FEDER (project CGL2009-11316/BOS

Multiplicity distribution and spectra of negatively charged hadrons in Au+Au collisions at sqrt(s_nn) = 130 GeV

The minimum bias multiplicity distribution and the transverse momentum and pseudorapidity distributions for central collisions have been measured for negative hadrons (h-) in Au+Au interactions at sqrt(s_nn) = 130 GeV. The multiplicity density at midrapidity for the 5% most central interactions is dNh-/deta|_{eta = 0} = 280 +- 1(stat)+- 20(syst), an increase per participant of 38% relative to ppbar collisions at the same energy. The mean transverse momentum is 0.508 +- 0.012 GeV/c and is larger than in central Pb+Pb collisions at lower energies. The scaling of the h- yield per participant is a strong function of pt. The pseudorapidity distribution is almost constant within |eta|<1.Comment: 6 pages, 3 figure
