Identifying habitation patterns in world heritage areas through social media and open datasets
Although cities with World Heritage (WH) areas worldwide are
socially active, specific social and cultural complexities are
associated primarily with the abandonment and decay of districts.
Contemporary habitation patterns in historic districts require
technology to understand parallel realities in protected areas.
This stakeholders-based approach benefits significantly from
cross-referencing locative social media and open data sources.
Therefore, the concepts put forward in this paper use evidence
from an empirical case of WH areas in selected Spanish urban
sites. The cartographic correlation of data identifies hotspots of
activities and coldspots around services within each site. The
results present two significant findings. The first confirms the
successful implementation of a digital method to support current
transitions for the historic city. The second demonstrates that
social networks and open datasets can mirror contemporary
social interaction in historic cities. Finally, the study calls on
further investigating Artificial Intelligence-based assessments for
the future of WH areas
The Heritagization of a Mediterranean Vernacular Mountain Landscape: Concepts, Problems and Processes
The concepts of heritage and landscape have always changed or been developed
based on the social context of the time. For decades, attempts have been made to
find a pragmatic definition for a changing setting where values, evolve or
disappear in step with the changing ways and styles of life of each society.
Heritage and landscape have inherent values such as identity, culture, authenticity
or integrity, that is to say, landscape character. Current heritagization processes
that lead to an understanding of the palimpsest of landscape and heritage layers
need to be participatory and inclusive as their importance and sustainability
depend on this. This article shows how the early stages of a heritagization process
unfold in a small region of the western Mediterranean, Penyagolosa (CastellĂłn).
The current problems of the region - depopulation, abandonment and loss of
culture and identity - are assessed in search of an understanding and appreciation
of a heritage landscape. The research uses techniques such as photo elicitation in
a workshops, GIS analysis and evaluates the different options to characterize the
landscape offered by different researchers. The analysis explains the different
phases of the research to establish the basis of the heritagization of this setting.
The study also established a parallel perspective for valorization between
researchers and local population - objective and subjective visions - thus
encouraging the interest of the social majority linked to the landscape
A Practical Vision of Heritage Tourism in Low-Population- Density Areas. The Spanish Mediterranean as a Case Study
Heritage tourism bases its definition on searching for different, authentic, and somewhat
unexplored places. Recent literature speaks of the growth of new forms of tourism based on the
tradition that seeks to surprise visitors with popular culture, traditional activities, or actions that
bring traditional culture closer to tourists. However, the reality is that the influx of tourists to small
mountain villages is marked by the most âmonumentalâ historical and architectural values, leaving
aside some other minor attributes. This article uses the historical centres of rural villages to place
inhabitantsâ knowledge at the centre of tourism initiatives. The aim of the study was to develop
cohesive and inclusive tourism activities in historic centres by analysing the built environmentâs
attributes and values. A participatory methodology marks the cultural change to enhance collaboration through transparent and ethical foundations and respect these placesâ distinctive character.
The study of values helped to conduct an in-depth analysis of local realities to document and map
historical centresâ tangible attributes through crafts, traditional culture, and local heritage forms
A GIS-based methodology for the appraisal of historical, architectural, and social values in historic urban cores
Historic environments represent the evolution of materials and techniques that
have been used for the construction these environments over the centuries. Entering into
the study of this field entails working not only on the crafts that have constructed these environments
but also on the people who made, used, and reinterpreted them by learning about
the craftsmen and the idiosyncrasies of the place. The study has adopted several methodologies
as reference to examine the material and cultural reality of the rural region of Valencia,
Spain. Through the adaptation of international methodologies, researchers have carried out a
digital database that compiles and maps out the results of the Local Character Assessment of
ten Histotiric Urban Cores by incorporating the historical, architectural, and social values to
reinforce the Territorial Heritage Action Plan. One of the critical innovations adopted by this
form of assessment is the compulsory integration of tangible and intangible heritage through
the active involvement of users and makers. Another innovation is to understand the values
behind the dynamism and transformation of historic sites. Hence, this study advances theory
and practice on the transmission of knowledge among artisans, researchers, and the population
and how contemporary practices help acquire new meanings that overlap the past ones
Examining urban polarization in five Spanish historic cities through online datasets and onsite perceptions
At present, the planning and management of historic districts are faced with the challenge of striking a balance
between the needs of residents and seasonal pressures from visitors. These socially bustling sites could also
benefit from the data cross-referencing of cultural and social patterns in order to identify areas for improvement.
This research analyses geo-referenced online datasets and data from social media applications, subsequently
contrasting these with onsite data from in-person interviews. These specific variables highlight parallels and
conflicts between districts designated World Heritage areas in five Spanish cities. The study provides a quantitative analysis of hotspots and coldspots within the built environment. This is followed by an examination of
these two types of areas using qualitative data linked to the three most challenging issues: housing and the built
environment; basic services; and cultural services. When analysing the future of historic districts three major
challenges to management highlighted in the results should be considered. Firstly, even in socially active districts, imbalances and dysfunctional areas are highlighted by both online data and onsite perceptions. Secondly,
the study of the dynamics of districts for observing how stakeholders adapt to this social, economic, and mobilityrelated polarization. Thirdly, while the study acknowledges the changes to the consumption of culture, there is
still potential for improvement in hosting alternative or countercultural movements.Funding for open access charge: CRUE-Universitat Jaume
Noise in Grover's Quantum Search Algorithm
Grover's quantum algorithm improves any classical search algorithm. We show
how random Gaussian noise at each step of the algorithm can be modelled easily
because of the exact recursion formulas available for computing the quantum
amplitude in Grover's algorithm. We study the algorithm's intrinsic robustness
when no quantum correction codes are used, and evaluate how much noise the
algorithm can bear with, in terms of the size of the phone book and a desired
probability of finding the correct result. The algorithm loses efficiency when
noise is added, but does not slow down. We also study the maximal noise under
which the iterated quantum algorithm is just as slow as the classical
algorithm. In all cases, the width of the allowed noise scales with the size of
the phone book as N^-2/3.Comment: 17 pages, 2 eps figures. Revised version. To be published in PRA,

Validity of Machine Learning in Assessing Large Texts Through Sustainability Indicators
As machine learning becomes more widely used in policy and environmental impact settings, concerns about accuracy and fairness arise. These concerns have piqued the interest
of researchers, who have advanced new approaches and theoretical insights to enhance
data gathering, treatment and modelsâ training. Nonetheless, few works have looked at the
trade-offs between appropriateness and accuracy in indicator evaluation to comprehend
how these constraints and approaches may better redound into policymaking and have a
more significant impact across culture and sustainability matters for urban governance.
This empirical study fulfils this void by researching indicatorsâ accuracy and utilizing
algorithmic models to test the benefits of large text-based analysis. Here we describe applied work in which we find affinity and occurrence in indicators trade-offs that result be
significant in practice to evaluate large texts. In the study, objectivity and fairness are kept
substantially without sacrificing accuracy, explicitly focusing on improving the processing
of indicators to be truthfully assessed. This observation is robust when cross-referring indicators and unique words. The empirical results advance a novel form of large text analysis through machine intelligence and refute a widely held belief that artificial intelligence
text processing necessitates either accepting a significant reduction in accuracy or fairness.Funding for open access charge: CRUE-Universitat Jaume

Para manejar esta gran cantidad de datos se propone el programa denominadaIRCA escrito en FORTRAN IV para utilizar con computadoras IBM modelos 1130 o 360
Assessment of the ecological role of historic centres based on the relationship between biodiversity and urban composition
Historic centres provide their inhabitants with identity and well-being. Although studies focus on
the conservation of the built environment, in recent years the environmental component of historic centres has also been analysed. Issues such as ecosystem services and biodiversity have
become more pressing due to rapid population growth, development and the climate crisis. Green
spaces in historic centres often conserve biodiversity, as they tend to be protected spaces. This
article presents two case studies in Castellon ÂŽ de la Plana (Spain) with the aim of analysing the
relationship between the built environment and avian biodiversity. The study uses a four-phase
process. The first phase incorporates a review of recent literature to select biodiversity indicators, while the second focuses on open data analysis and incorporation into GIS software. The
third phase consists of field data collection and the mapping of biodiversity indicators. Finally,
phase four involves the preparation of thematic maps, which allows us to visualize behavioural
patterns connecting bird colonies with the morphology of the built environment in order to draw
relevant conclusions that can help improve biodiversity. The analysis allowed the calculation of
eight indicators and the identification of building typologies, the percentage of green areas and
the inspection of features promoting avian biodiversity. In total, 31 bird species were detected, 27
in the historic centre of Castellon ÂŽ and 26 in the historic centre of the Grao district. Among them,
the mapping distribution of three endangered species demonstrates their dependence on these
historic built habitats. Apus apus, Passer domesticus and Delichon urbicum are present in 97, 82 and
56% of grids, respectively, with ANOVA correlation confirming these species densities found. The
study is somewhat limited in the use of the line transect method due to the potential structural
biases intrinsic to the unique nature of the districts assessed
Fluid intake habits of spanish children and adolescents: an update of the Liq.In7 survey
Insufficient and unhealthy total fluid intake (TFI), especially in early stages of life, may have negative health impact [1]. Understanding how fluid consumption may differ throughout the day or as a function of location could help drive policy initiatives to encourage healthier drinking habits, especially in young population groups, so this study assesses current patterns of fluid consumption in children and adolescents in Spain, including drinking occasions and locations and to compare TFI with the adequate intake of water from fluids recommended by the European Food Safety Authority (EFSA)..
