Rethinking Secular Time in Victorian England

2022

This open access book draws on conceptual resources ranging from medieval scholasticism to postmodern theory to propose a new understanding of secular time and its mediation in nineteenth-century technological networks. Untethering the concept of secularity from questions of ‘religion’ and ‘belief’, it offers an innovative rethinking of the history of secularisation that will appeal to students, scholars, and everyone interested in secularity, Victorian culture, the history of technology, and the temporalities of modernity.

Towards the specification of a self-exciting point process for modelling crimes in Valencia

2023

A number of papers have dealt with the analysis of crime data using self-exciting point process theory after the analogy drawn between aftershock ETAS models and crime rate. With the aim to describe crime events that occurred in Valencia in the last decade, in this paper, we justify the need for a self-exciting point process model through spatial and temporal exploratory analysis.

The article explores the dimension of temporality and the changes it has undergone as a result of the pandemic outbreak.

Age-related changes in the regulation of transcription factor NF-kappa B in rat brain.

1997

Aging process involves an increase in stress at cellular level. We studied whether aging affects the regulation of stress responsive transcription factor NF-kappa B in brain samples of Wistar rats. Hippocampus, cerebellum, and temporal and frontal lobes of cortex were studied. We observed a significant up-regulation in the constitutive, nucleus-located NF-kappa B binding activity in 30-month-old Wistar rats compared to young and 18-month-old rats. The increase was most prominent in cerebellum and in frontal cortex, but age-related changes did not occur in hippocampus. Inducible, cytoplasmic NF-kappa B binding activity was not affected by aging in any of the samples studied. Western blot ass…

Neurobiological foundations of multisensory processing integration in people with autism spectrum disorders: The role of the medial prefrontal cortex

2014

This review aims to relate the sensory processing problems in people with Autism spectrum disorders (ASD), especially Multisensory interaction (MSI), to the role of the medial prefrontal cortex (mPFC) by exploring neuroanatomical findings; brain connectivity and Default Network (DN); global or locally directed attention; and temporal multisensory binding. The mPFC is part of the brain’s DN, which is deactivated when attention is focused on a particular task and activated on rest when spontaneous cognition emerges. In those with ASD, it is hypoactive and the higher the social impairment the greater the atypical activity. With an immature DN, cross-modal integration is impaired, resulting in …

Healthcare trajectory mining by combining multidimensional component and itemsets

2012

Sequential pattern mining is aimed at extracting correlations among temporal data. Many different methods were proposed to either enumerate sequences of set valued data (i.e., itemsets) or sequences containing multidimensional items. However, in real-world scenarios, data sequences are described as events of both multidimensional items and set valued information. These rich heterogeneous descriptions cannot be exploited by traditional approaches. For example, in healthcare domain, hospitalizations are defined as sequences of multi-dimensional attributes (e.g. Hospital or Diagnosis) associated with two sets, set of medical procedures (e.g. $ \lbrace $ Radiography, Appendectomy $\rbrace$) and…

Alle origini della deissi indoeuropea. Un approccio linguistico cognitivo

Gli studi di indoeuropeistica non sempre dialogano con le teorie linguistiche contemporanee e, in particolare, con le scienze cognitive (cfr. Melchert 2016). Tuttavia, il contributo che le seconde possono dare alla ricostruzione di fenomeni linguistici e culturali indoeuropei non è trascurabile. Non è d’altra parte meno rilevante l’apporto che la prospettiva storica può dare allo studio dei processi cognitivi umani, dall’acquisizione del linguaggio da parte dei bambini fino all’individuazione degli universali linguistici. Scopo di questo studio è discutere i risultati di una recentissima ricerca (Bartolotta 2018), che mostra il ruolo dell’indoeuropeo nella spiegazione degli universali lingu…

Serializing Age

2015

Serialized storytelling provides intriguing opportunities for critical representations of age and aging. In contrast to the finite character of films, television narratives can unfold across hundreds of episodes and multiple seasons. Contemporary viewing practices and new media technologies have resulted in complex television narratives, in which experimental temporalities and revisions of narrative linearity and chronological time have become key features. As the first of its kind, this volume investigates how TV series as a powerful cultural medium shape representations of age and aging, such as in »Orange Is The New Black«, »The Wire« or »Desperate Housewives«, to understand what it mean…

Deep learning for agricultural land use classification from Sentinel-2

2020

[ES] En el campo de la teledetección se ha producido recientemente un incremento del uso de técnicas de aprendizaje profundo (deep learning). Estos algoritmos se utilizan con éxito principalmente en la estimación de parámetros y en la clasificación de imágenes. Sin embargo, se han realizado pocos esfuerzos encaminados a su comprensión, lo que lleva a ejecutarlos como si fueran “cajas negras”. Este trabajo pretende evaluar el rendimiento y acercarnos al entendimiento de un algoritmo de aprendizaje profundo, basado en una red recurrente bidireccional de memoria corta a largo plazo (2-BiLSTM), a través de un ejemplo de clasificación de usos de suelo agrícola de la Comunidad Valenciana dentro d…

Should conference pricing mechanisms incorporate options?

2016

The provision of many services is often characterized by demand uncertainty, as, at the time of purchase, consumers may not be completely informed about their valuation for the service or the possibility to utilize the service when it will actually be provided. For such reason, service providers implement several pricing mechanisms to maximize their profits in presence of consumer uncertainty and heterogeneity. A commonly adopted mechanism is intertemporal price discrimination, under which service providers charge different prices to consumers buying at different times. For instance, a lower price is usually offered to consumer buying early in advance, whereas higher price is practiced to l…
