STATISTICAL MODELS FOR LANDSLIDE SUSCEPTIBILITY ASSESSMENT: METHODOLOGICAL ISSUES AND GUIDELINES FOR MEDITERRANEAN CONTEXT
2012
La población mundial, que cuenta dos mil millones de habitantes alrededor del año 1950, ha crecido a un ritmo casi exponencial en las décadas siguientes hasta 4 mil millones y 5,3 en 1990 (Naciones Unidas - Departamento de Asuntos Económicos y Sociales, 2010). Sin duda un gran aumento tanto en términos absolutos cuanto relativos. Según las estimaciones de las Naciones Unidas, la población mundial se estima que alcanzará los ocho millones y medio de 2025. Estas tasas de crecimiento se producen, obviamente, tanto en Europa, donde la población ha crecido de 550 millones en 1950 a 750 millones en 2010, y en Italia, donde en el período 1861 a 2008 hubo un aumento de la población de 22 millones d…
The geo-hydrologic event in the Peloritan – Ionian area of 2009: debris-flow susceptibility assessment by means of forward logistic regression
2012
On the 1st of October 2009, the area centred on the village of Giampilieri (Messina), on the Ionian side of the Peloritan belt, suffered thousands of landslides activated in the time lapse of about five hours, which caused 36 victims, more than 100 injured and more than 0.5M€ of damage to structures. This unprecedented phenomenon was triggered by an exceptional meteorological event, recorded at the foothills with 250mm of rain in just 8 hours; this amount of rainfall was cumulated to two previous events (16/IX: 75mm; 23/IX: 190mm) for a total amount of more than 500mm in less than two weeks. Due to the peculiar triggering conditions a huge number of debris flows involved the shallow weather…
Declines in Sexual Activity and Function Predict Incident Health Problems in Older Adults: Prospective Findings from the English Longitudinal Study o…
2020
The objective of this study was to investigate cross-sectional and longitudinal associations between declines in sexual activity and function and health outcomes in a large population-based sample of older adults. Data were from 2577 men and 3195 women aged ≥ 50 years participating in the English Longitudinal Study of Ageing. Past-year changes in sexual desire, frequency of sexual activity, and ability to have an erection (men)/become sexually aroused (women) were assessed at baseline by self-completion questionnaire. Health outcomes (self-rated health, limiting long-standing illness, doctor-diagnosed diseases of the vascular system, and cancer) were self-reported at baseline (2012/2013) an…
The effects of using participatory working time scheduling software on working hour characteristics and wellbeing : a quasi-experimental study of irr…
2020
Background: Studies in the health care sector indicate that good work time control is associated with better perceived wellbeing but also with non-ergonomic work schedules, such as compressed work schedules. Participatory working time scheduling is a collaborative approach to scheduling shift work. Currently, there is a lack of information on whether working hour characteristics and employees' wellbeing in irregular shift work change after implementing participatory working time scheduling. Objective: To investigate the effects of using digital participatory working time scheduling software on working hour characteristics and well-being among Finnish hospital employees. Participants and met…
Exploring the effects of gender, age, income and employment status on consumer response to mobile advertising campaigns
2008
PurposeThe purpose of this paper is to examine the effects gender, age, income and employment status on consumer response to short message service (SMS)‐oriented direct‐response requests or a call‐to‐action tactic in a television advertisement or program, consumer's participation in SMS sweepstakes or other competitions, and consumer uptake of mobile services such as ringtones, logos, screensavers and wallpapers ordered by SMS message.Design/methodology/approachThe data used in this study were collected via an online survey. A total of 4,062 consumers responded to this survey. Cross‐tabulation and binary logistic regression were used to examine the associations between the explanatory varia…
Sleep disorders in the elderly with and without chronic airflow obstruction: the SARA study
2003
Objectives: Our objectives were to test the hypothesis that, in the geriatric population, chronic airway obstruction is associated with a higher prevalence of sleep disturbances; to identify the main correlates of sleep disturbances, and to verify whether asthma and COPD patients have different patterns of sleep disturbances. Methods: The EPESE questionnaire was administered to 734 patients aged 65 years and over with asthma or chronic obstructive pulmonary disease (cases) and 1237 individuals of comparable age who were free of respiratory disease but not of other chronic conditions (controls). Four sleep disturbances were quantified: difficulty in falling asleep, nocturnal awakening, morni…

Relationship between socioeconomic factors and intelligence of preschoolers: A cohort study in the Serbian context
2020
The aim of the current research is to analyse the relationship between the socioeconomic status (SES) of parents and intellectual abilities (IQ) of preschool children of Serbian territory, and in particular how SES factors relate to preschool children’s IQ measured with Raven’s Coloured Progressive Matrices (CPM), in the different age groups. The research included 430 parents and 430 preschool children. A confirmatory factor analysis of the SES questionnaire revealed five factors: educational and professional status of father and mother, residential and educational status of the family, sport status of parents and comfort of family housing. No gender differences in IQ levels were found in c…
Análisis de la realidad sociolingüística del valenciano
2011
Se analiza la situación actual del uso y la percepción social del valenciano entre los habitantes del País Valenciano a partir de los estudios realizados por el Centro de Investigaciones Sociológicas. Para ello, se presta especial atención a variables sociodemográficas a partir de análisis estadístico multivariante con distribuciones de frecuencias bivariadas, análisis de segmentación y regresión logística. El estudio concluye que se produce un estancamiento en el porcentaje de hablantes del valenciano y que las personas de izquierdas y con mayor nivel de estudios son quienes se postulan más a favor de la unidad del valenciano con el catalán. Palabras clave: sociolingüística; diglosia; esta…
