La innovación empresarial y la difusión como nuevos factores de desarrollo territorial. Una comparación entre dos áreas geográficas de diferente acce…

2003

Javier.Esparcia@uv.es Joan.Noguera@uv.es Vicente.Ferrer@uv.es El proyecto AsPIRE (Perifericidad No Espacial, Innovación y la Economía Rural) intenta dar respuesta a algunas de las dudas que están surgiendo en ciertos modelos geo-económicos tradicionales. El desarrollo de otros factores parece que puede suplir parcialmente las deficiencias ligadas a la localización geográfica. La comunicación que presentamos se centra en el papel de la innovación y las redes empresariales como uno de los factores emergentes de desarrollo territorial. The AsPIRE Project (Aspatial Peripherality, Innovation and the Rural Economy intends to provide a scientifically valid answer to some of the problems arising in…

Characteristics and definition and characterization of new Valencian urban areas

2014

La expansión urbanística, junto con la generalización de los procesos de descentralización residencial y económica, ha conducido a un nuevo modelo de ciudad dispersa caracterizado por la dificultad de establecer sus límites precisos. Utilizando un índice de densidad de ejes viarios procedente de una fuente comercial, y por tanto fácilmente actualizable, se ha delimitado el fenómeno urbano en la Comunidad Valenciana. Se discute la utilidad de la metodología y su capacidad para captar el hecho urbano a partir del contraste con la cartografía de usos del suelo de Corine. Urban expansion, along with the generalization of the processes of residential and economic decentralization has led to a ne…

The effect of body shape and gender on wireless Body Area Network on-body channels

2010

Technological advancements have made possible the emergence of Body Area Networks (BANs). There are numerous on-body channel characterizations in the literature performed on a phantom or a single human subject. In this paper, using multiple subjects, we consider the effect of body shape and gender on the on-body channel. A characterization of a narrowband on-body to on-body channel among different subjects is presented. The paper investigates the relationship between the propagation and the subject's physical characteristics. The investigation is performed at 2360 MHz; the new medical band undergoing FCC approval. Our results show that the path loss in women is less than that in men and the…

Special track on Geometric Constraints and Reasoning

2008

Geometric Computing and Reasoning (GCR) aims at emphasizing recent trends in the domain of geometric constraint solving and automated, or computer aided deduction in geometry. This year sees the third edition of this technical track of SAC.

Happy Aged People Are All Alike, While Every Unhappy Aged Person Is Unhappy in Its Own Way

2011

Aging of the world’s population represents one of the most remarkable success stories of medicine and of humankind, but it is also a source of various challenges. The aim of the collaborative cross-cultural European study of adult well being (ESAW) is to frame the concept of aging successfully within a causal model that embraces physical health and functional status, cognitive efficacy, material security, social support resources, and life activity. Within the framework of this project, we show here that the degree of heterogeneity among people who view aging in a positive light is significantly lower than the degree of heterogeneity of those who hold a negative perception of aging. We base…

Computers and the Internet in cardiac care: Will cardiology rise to this extraordinary opportunity?

Complementary frailty and mortality prediction models on older patients as a tool for assessing palliative care needs.

2021

Background: Palliative care (PC) has demonstrated benefits for life-limiting illnesses. Cancer patients have mainly accessed these services, but there is growing consensus about the importance of promoting access for patients with non-malignant disease. Bad survival prognosis and patient9s frailty are usual dimensions to decide PC inclusion. Objectives: The main aim of this work is to design and evaluate three quantitative models based on machine learning approaches to predict frailty and mortality on older patients in the context of supporting palliative care decision making: one-year mortality, survival regression and one-year frailty classification. Methods: The dataset used in this stud…

Management of Childhood Obesity—Time to Shift from Generalized to Personalized Intervention Strategies

2021

As a major public health concern, childhood obesity is a multifaceted and multilevel metabolic disorder influenced by genetic and behavioral aspects. While genetic risk factors contribute to and interact with the onset and development of excess body weight, available evidence indicates that several modifiable obesogenic behaviors play a crucial role in the etiology of childhood obesity. Although a variety of systematic reviews and meta-analyses have reported the effectiveness of several interventions in community-based, school-based, and home-based programs regarding childhood obesity, the prevalence of children with excess body weight remains high. Additionally, researchers and pediatric c…

Spatio-Temporal Linear Network Point Processes for GPS Data Analysis

This work aims at analyzing the spatio-temporal intensity in the distribution of stop locations of cruise passengers during their visit at the destination. Data are collected through the integration of GPS tracking technology and questionnaire-based survey on a sample of cruise passengers visiting the city of Palermo (Italy), and they are used to identify the main determinants which characterize cruise passengers’ stop locations pattern. The spatio-temporal distribution of visitors' stops is analysed by mean of the theory of stochastic point processes occurring on linear networks, in order to consider the street configuration of the city and the location of the main attractions. First, an i…

Defects in glasses

1995

Abstract The absence of long range order in the glass structure allows to define only point defects in these materials. They are: 1) intrinsic defects—atomic size local deviation from short range order; 2) impurity defects—isolated impurity atoms or ions in the glass network; 3) intrinsic impurity defects—complexes consisting of the impurity atoms chemically bonded to one of the intrinsic defect atoms. The latter defects are characteristic for the doped glasses. Presence of point defects in glasses introduces new spectroscopic properties of these solid materials. Defect generation, interaction and recombination reactions resulting from the external influence causes the glass spectroscopic p…
