Estudio demográfico de Aldaia (1669-1890)

1995

El descubrimiento en los últimos años de los archivos parroquiales (cuando existían), así como los avances producidos en materia de demografía histórica, han permitido a un buen número de estudiosos aproximarse al estudio de la población desde el ámbito local. En esta linea se enmarca el presente artículo, teniendo como escenario una población cercana a la ciudad de Valencia, Aldaia. El movimiento seguido por esta localidad puede definirse en una sola palabra como ascendente, motivado tanto por causas endógenas como exógenas. Por otro lado la proximidad a la capital valenciana será un elemento a tener en cuenta en todo momento. Por último recordar, desde esta pequeña aportación, la brillant…

A Spatial Difference-in-Differences Estimator to Evaluate the Effect of Change in Public Mass Transit Systems on House Prices

2014

Evaluating the impact of public mass transit systems on real-estate values is an important application of the hedonic price model (HPM). Recently, a mathematical transformation of this approach has been proposed to account for the potential omission of latent spatial variables that may overestimate the impact of accessibility to mass transit systems on values. The development of a Difference-in-Differences (DID) estimator, based on the repeat-sales approach, is a move in the right direction. However, such an estimator neglects the possibility that specification of the price equation may follow a spatial autoregressive process with respect to the dependent variable. The objective of this pap…

409 Using rai-hc assessment instrument to classify home care clients in Finland based on fire emergency evacuation capacity

2016

Background When an uncontrollable fire is detected in a building there may be a 2–3 minutes window for the occupants to move to safety. Poor physical function and cognition may become critical factors in an evacuation situation. In this study a novel functional scale measuring emergency evacuation capacity of home care clients is presented. Methods A fire security expert visited about 250 home care clients assessing their evacuation capacities. For the evacuation capacity three categories were used: 1) is able to evacuate; 2) may be able; 3) unable to evacuate. This data was linked to comprehensive assessments of clients functional and health status performed by home care nurses using the i…

Relationship between Perception and Socio-Economic Characteristics of Culture Community in the Development of Marine Ecotourism in Nusmapi Island

2021

Marine tourism is a type of special interest tourism, namely by managing and utilizing marine and coastal landscapes, both those that are managed directly such as swimming, boating, snorkeling, diving, or indirectly such as picnics and beach sports. Nusmapi Island has the potential to be developed as a marine tourism object which has the potential for waters and coral reefs that are in good condition. The purpose of this study was to determine the relationship between the level of public perception and the socio-economic conditions of the local community on Nusmapi Island. In October-November 2020 this research was carried out on Nusmapi Island, Manokwari Regency. The descriptive explorator…

Psychometric properties on a romantic love myths scale: The case of the myths, fallacies and erroneous beliefs about the ideal of romantic love scale

2021

Understanding the construct of romantic love is an important task in societies all around the world. However, instruments designed to assess this construct are scarce and most of them were developed more than a decade ago. De la Peña, Ramos, Luzón, and Recio (2011) proposed the Myths, Fallacies and Erroneous Beliefs about the Ideal of Romantic Love Scale. In this current study we provide the psychometric properties of this scale in a representative sample of adolescents. The analytic strategy included both Exploratory Factor Analysis and Confirmatory Factor Analysis. We achieved a best-factor structure using a unidimensional model of romantic beliefs which also had an adequate estimated rel…

The Perception and Attitudes Towards City Garbage Management: A First Analysis

2017

The main aim of this paper is to to explore the perception and attitude of people toward an important issue like the City Garbage Management. A new Survey Questionnaire to measure the perception and attitudes towards city garbage management has been developed by the Authors, in order to realize a very first analysis of compatibility of the Comprehensive Action Determination Model - CADM (Klöckner, 2013) with City Garbage Management issues. To test the application of the CADM model to City Garbage Management, a simple linear regression was calculated to predict the dependent variables based on predictor variables according the CADM model. The linear regression analysis shows a first confirma…

Varying numbers of players in small-sided soccer games modifies action opportunities during training

2014

This study examined the effects of the numbers of players involved in small-sided team games (underloading and overloading) on opportunities for maintaining ball possession, shooting at goal and passing to teammates during training. These practice constraint manipulations were assumed to alter values of key performance variables identified in previous research, such as interpersonal distances between players and time to intercept shots and passes. Fifteen male soccer players (age: 19.60±1.99 years) were grouped into three teams and played against each other in different versions of small-sided soccer games, in which the number of players was manipulated in three different conditions: 5 vs. …

Relationship between perception of malocclusion and the psychological impact of dental aesthetics in university students.

2014

Introduction and Objectives: The objectives were to assess the relationship between perceived smile aesthetics and perceived psychological impact as measured by the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and their own perception of it using the Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC) and a Visual Analog Scale (VAS); relate the IOTN-AC and VAS to the PIDAQ; and study the predictive capacity of the scales for psychological impact. Material and Methods: A cross-sectional study was conducted in 447 college students in Spain and Portugal (average age 20.4 years, 33.1% men and 66.9% women). The online self-completed surveys used the recent…

Pseudodifferential operators of Beurling type and the wave front set

2008

AbstractWe investigate the action of pseudodifferential operators of Beurling type on the wave front sets. More precisely, we show that these operators are microlocal, that is, preserve or reduce wave front sets. Some consequences on micro-hypoellipticity are derived.

Double point curves for corank 2 map germs from C2 to C3

AbstractWe characterize finite determinacy of map germs f:(C2,0)→(C3,0) in terms of the Milnor number μ(D(f)) of the double point curve D(f) in (C2,0) and we provide an explicit description of the double point scheme in terms of elementary symmetric functions. Also we prove that the Whitney equisingularity of 1-parameter families of map germs ft:(C2,0)→(C3,0) is equivalent to the constancy of both μ(D(ft)) and μ(ft(C2)∩H) with respect to t, where H⊂C3 is a generic plane.
