Reestimating a minimum acceptable geocoding hit rate for conducting a spatial analysis
2019
Geocoding consists in converting a textual description of a location into coordinates. Hence, geocoding a dataset of events has to be carried out before performing a spatial analysis of some data. ...
Population geocoding for healthcare management. Technical challenges and quality issues
2015
The present work aims at describing the main issues related with population geocoding for healthcare management. Some of the available procedures for geocoding multiple addresses are described and an indicator of quality of the geocoded addresses is proposed. As a case study, the geocoding of population addresses of a set of 9 Sicilian Municipalities is described and results deriving from the use of two different methods are compared in terms of quality. Some potential applications of population geocoding in healthcare management are finally discussed.
Automatic research of the capitalization rate for the residential automated valuation: an experimental study in Cosenza (Italy).
2017
When a market oriented approach is not applicable because of the lack of comparable sales data (Ciuna et al. 2014a), International Valuation Standards suggest the use of the Income Approach, which has the task of simulating the market through an economic and financial scheme. The central question of this approach is due to the quantification of the capitalization rate, whereas it is generally extracted in a market segment different from that of the subject. This paper intends to propose an automated valuation model of the capitalization rate based on a real estate database built through a computerized geocoding automatic procedure, starting from the application of statistical models of mult…
Effect of traffic proximity of lung function in asthmatic children
2014
Introduction Respiratory conditions are strongly dependent on air pollution. Urban areas are typically characterized by risky environmental conditions, especially due to traffic congestion. Indeed, there may be important variations in environmental quality even within urban areas. Objectives To analyze the effect of traffic proximity on asthma and to explore the relationship between level of traffic proximity and lung function in both asthmatic children and non-asthmatic children. Methods A case-control study on children visited for suspected respiratory diseases at IBIM from September 2011 to May 2014 was performed. All the children have been geocoded according to their residence address. …
SOLUZIONI OPERATIVE ED ASPETTI QUALITATIVI PER LA GEOCODIFICA DI POPOLAZIONI IN AMBITO SANITARIO.
2015
IntroduzioneL'utilizzo dei Geographic Information Systems (GIS) in ambito sanitario, continua a ricevere grande attenzione. La disponibilità di informazioni sulla localizzazione degli individui, consente di effettuare associazioni territoriali sulle cause delle patologie, nonché di indagare aspetti legati alla distribuzione dei servizi sanitari ed all'equità di accesso alle cure. ObiettiviAnalizzare le principali problematiche e le soluzioni operative per la geocodifica di popolazioni e proporre un indice di qualità della geocodifica di cui poter tenere conto in sede di analisi. MetodiCome caso studio vengono illustrate le fasi che hanno portato alla georeferenziazione di indirizzi residenz…
Two-level resolution of relative risk of dengue disease in a hyperendemic city of Colombia.
2018
Risk maps of dengue disease offer to the public health officers a tool to model disease risk in space and time. We analyzed the geographical distribution of relative incidence risk of dengue disease in a high incidence city from Colombia, and its evolution in time during the period January 2009—December 2015, identifying regional effects at different levels of spatial aggregations. Cases of dengue disease were geocoded and spatially allocated to census sectors, and temporally aggregated by epidemiological periods. The census sectors are nested in administrative divisions defined as communes, configuring two levels of spatial aggregation for the dengue cases. Spatio-temporal models including…
Socio-economic determinants of inter-regional mobility in patients with cancer
2017
This paper presents an investigation of inter-regional mobility in patients with cancer. Thanks to the availability of geocoded information on patients’ place of residence, the effect of socio-economic status and of other individual characteristics on inter-regional mobility is analysed through multi-level logit models. The extent of patient’s mobility, and its dependence on socio-economic status raises equity issues, as well as regional policy considerations.
Individual and contextual determinants of inter-regional mobility in cancer patients
2019
This paper will present an investigation of inter-regional mobility in patients with a diagnosis of cancer. By virtue of the availability of geocoded information relating to a patient's place of residence, the effect of socio-economic status and other individual characteristics regarding inter-regional mobility will be analysed by means of multilevel logit models. The results demonstrate the influence of age and comorbidity on mobility propensity, in addition to the treatment type, which plays a role in patient mobility. As contextual determinants, patients residing in less deprived areas show greater mobility than those who reside in materially deprived areas. The extent of patient mobilit…
The Spatial Overlap of Police Calls Reporting Street-Level and Behind-Closed-Doors Crime: A Bayesian Modeling Approach
2021
Traditionally, intimate-partner violence has been considered a special type of crime that occurs behind closed doors, with different characteristics from street-level crime. The aim of this study is to analyze the spatial overlap of police calls reporting street-level and behind-closed-doors crime. We analyzed geocoded police calls in the 552 census-block groups of the city of Valencia, Spain, related to street-level crime (N = 26,624) and to intimate-partner violence against women (N = 11,673). A Bayesian joint model was run to analyze the spatial overlap. In addition, two Bayesian hierarchical models controlled for different neighborhood characteristics to analyze the relative risks. Resu…
