State-Space Methods for Time Series Analysis
by Jose Casals, Alfredo Garcia-Hiernaux, Miguel Jerez, Sonia Sotoca, A. Alexandre Trindade
2018 · CRC Press
The state-space approach provides a formal framework where any result or procedure developed for a basic model can be seamlessly applied to a standard formulation written in state-space form. Moreover, it can accommodate with a reasonable effort nonstandard situations, such as observation errors, aggregation constraints, or missing in-sample values. Exploring the advantages of this approach, State-Space Methods for Time Series Analysis: Theory, Applications and Software presents many computational procedures that can be applied to a previously specified linear model in state-space form. After discussing the formulation of the state-space model, the book illustrates the flexibility of the state-space representation and covers the main state estimation algorithms: filtering and smoothing. It then shows how to compute the Gaussian likelihood for unknown coefficients in the state-space matrices of a given model before introducing subspace methods and their application. It also discusses signal extraction, describes two algorithms to obtain the VARMAX matrices corresponding to any linear state-space model, and addresses several issues relating to the aggregation and disaggregation of time series. The book concludes with a cross-sectional extension to the classical state-space formulation in order to accommodate longitudinal or panel data. Missing data is a common occurrence here, and the book explains imputation procedures necessary to treat missingness in both exogenous and endogenous variables. Web Resource The authors’ E4 MATLAB® toolbox offers all the computational procedures, administrative and analytical functions, and related materials for time series analysis. This flexible, powerful, and free software tool enables readers to replicate the practical examples in the text and apply the procedures to their own work.
The nervous system has a remarkable capacity for self-reorganization, and in this first systematic analysis of the interaction between hormones and brain plasticity, Luis Miguel Garcia-Segura proposes that hormones modulate metaplasticity in the brain. He covers a wide variety of hormones, brain regions, and neuroplastic events, and also provides a new theoretical background with which to interpret the interaction of hormones and brain remodeling throughout the entire life of the organism.Garcia-Segura argues that hormones are indispensable for adequately adapting the endogenous neuroplastic activity of the brain to the incessant modifications in external and internal environments. Their regulation of neuroplastic events in a given moment predetermines new neuroplastic responses that will occur in the future, adapting brain reorganization to changing physiological and behavioral demands throughout the life of the organism. The cross-regulation of brain plasticity and hormones integrates information originated in multiple endocrine glands and body organs with information coming from the external world in conjunction with the previous history of the organism. Multiple hormonal signals act in concert to regulate the generation of morphological and functional changes in neural cells, as well as the replacement of neurons, glial, and endothelial cells in neural networks. Brain remodeling, in turn, is involved in controlling the activity of the endocrine glands and regulating hormonal secretions. This bidirectional adjustment of brain plasticity in response to hormonal inputs, and adjustment of hormonal concentrations in response to neuroplastic events are crucial for maintaining the stability of the inner milieu and for the generation of adequate behavioral responses in anticipation of--and in adaptation to--new social and environmental circumstances and life events, including pathological conditions.
AC/E Digital Culture Annual Report.
by Javier Celaya, Jovanka Adzic, Luis Miguel Cencerrado, Pablo Gervás, José Manuel Menéndez, Elena Neira, Emma Rodero, Nuria Rodríguez, Mario Tascón, Elisa Yuste
2018 · Acción Cultural Española, AC/E
The AC/E Digital Culture Annual Report is a publication which looks at the impact of the internet on our society. Its aim is to delve into the transformation happening within the arts and culture sector and to help entities and professionals create experiences that are in line with the expectations of 21st century consumers. The first part of the 2018 edition brings together texts from professionals in the arts and culture sector as well as from experts in the digital field, in order to get up to speed on important issues regarding main trends. Every year the second part of the edition (Focus) looks at the changes happening among readers and reading material. The aim is to outline a map of digital reading material. Mario Tascón takes a close look at our most connected cities that have been created by the latest interconnected devices and the Internet of Things. He then analyses the role that cultural spaces are destined to perform within these cities. Next, JosО Manuel MenОndez and David Jimeno Bermejo describe the latest challenges faced by immersive technologies and its growing role within the ecosystem of digital content. The Experimental UNIT of the University of Valencia reviews its experience with the use of digital design and analyses how the latest possibilities of mobile devices can offer resources for the construction of the museography debate. Jovanka Adzic discusses a burning issue. In her analysis on the evolution of social networks and their continuously expanding influence on our way of life, she also takes a look at the problem of fake news on the internet. Jovanka goes on to refl ect on the competitive advantage of FANG obtained through large volumes of social data, within an economy driven by Big Data. Elena Neira takes a look at the impact of consumption of on-screen culture and the business models that are based on subscriptions— the so-called “Netfl ix model”. And Emma Rodero – in line with this year’s central theme of Focus – examines the theme of orality and analyses the growing influence of sound and voice in the digital era. Pablo GervЗs builds on the concept of computational creativity and its impact on literary creation. We have a total of seven articles by renowned experts to help us learn and reflect on the changes affecting our society as a whole and to give us a glimpse of new opportunities for the sector of arts and culture. Every year the second part of the edition (Focus) reflects and explains – through the use of best-practice examples both nationally and internationally – the biggest changes happening among readers and reading material in the digital era. The main objective of this section is to present a unified view on the matter. Authors Luis Miguel Cencerrado, Elisa Yuste and Javier Celaya outlines a map to help us navigate with ease through all types of texts; highlighting the role of the reader in the current context of hybrid literature (paper, digital, audio, visual, transmedia, etc.) which is favoured by the digital era we live in. The annual review is published in both Spanish and English, in PDF and EPUB format and can be downloaded for free under the licence of Creative Commons. The publication can be downloaded on the AcciЧn Cultural EspaЦola website in the section digital publications. A copy can also be obtained from major distributors of national and international digital books.
