Environment, wealth, inequality and the burden of disease in the Accra metropolitan area, Ghana
2005
The study examines environmental problems and adverse impacts on the health of urban households in the Accra metropolitan area, Ghana. Accra is faced with severe inadequacy of urban infrastructure in the face of rapid population growth in the metropolis. More than half of the city's population do not have access to solid waste collection services. Only 39.8% of households have indoor pipe and over 35.0% of households depend on unsanitary public latrines whilst 2.5% do not have access to toilet facilities. Human excrement, garbage and wastewater are usually deposited in surface drains, open spaces and streams in poor neighbourhoods. The resultant poor sanitation has serious health impacts as…
The Analysis of Large-scale Retail Trade Groups Customer Satisfaction: A Comparison Between CAPI and PAPI Data Collection Methods
2008
Computer assisted personal interviewing (CAPI) and similar electronic survey data collection methods seem to improve both technical and economical efficiency and data quality. Compared to traditional paper and pencil interviewing (PAPI) CAPI is affected by some shortcomings yet. At the end, the selection of one among many data collection methods has to be justified in terms of a profitable ratio between scientific and organizational costs and benefits. In this paper we discuss the (quasi)experimental design arranged in order to assess the differential effects of face-to-face paper and computer assisted interviewing in terms of efficacy, efficiency and the production of non-sampling errors. …
3D digital tools for the archaeological massive artifacts documentation
2022
This study focuses on 3D acquisition and documentation procedures, innovating and implementing traditional survey methods to promote and increase the efficacy of the historical and archaeological heritage fruition. Especially within museum itineraries, modern digital technologies, if consistently applied, can promote a better interpretative reading, implementing the knowledge of scholars. Moreover, in coherence with the Horizon Europe “Cultural Heritage” area of intervention, for a new future inextricably linked to the history of Cultural Heritage, it is essential to experiment approaches that favor innovative mechanisms of fruition and promotion of works of art, based on the idea that the …
Metal speciation in biological fluids — a review
1996
The literature on the speciation of metal ions in biological fluids is comprehensively reviewed. Critical examination on this subject reveals that major work has been done in blood and urine. Speciation in materials like milk has not yet been widely studied. On the other hand, only few references could be found on sweat, saliva, cell lysate, cerebrospinal, seminal, tear and bronchoalveolar fluids. The topics studied for these fluids were mainly the speciation of arsenic, mercury, aluminium and selenium. Work on the speciation of other elements like zinc, chromium, cadmium, lead, copper, iron etc. have also been carried out in such matrices. The present literature survey includes also a crit…
Translation and adaptation to spanish language of the quality of life questionnaire for celiac people called Canadian Celiac Health Survey
2014
Introducción: Adaptar y valorar el cuestionario de calidad de vida denominado Canadian Celiac Health Survey (CCHS). Objetivo: Traducir y adaptar en castellano el cuestionario CCHS para poder ser utilizado por la población de habla hispana puesto que se trata de un cuestionario específico para la celiaquía. Método: La adaptación del CCHS, que consta de 76 ítems distribuidos en 11 secciones diferentes, se realizó mediante el método de traducción-retrotraducción y tras ser revisado y consensuado se procedió a realizar una prueba piloto con 25 personas celíacas, de forma individual y por un miembro del grupo de investigación, para valorar la comprensión de los ítems y sus secciones. Las aportac…

Underuse of long-term routine hospital follow-up care in patients with a history of breast cancer?
2011
Abstract Background After primary treatment for breast cancer, patients are recommended to use hospital follow-up care routinely. Long-term data on the utilization of this follow-up care are relatively rare. Methods Information regarding the utilization of routine hospital follow-up care was retrieved from hospital documents of 662 patients treated for breast cancer. Utilization of hospital follow-up care was defined as the use of follow-up care according to the guidelines in that period of time. Determinants of hospital follow up care were evaluated with multivariate analysis by generalized estimating equations (GEE). Results The median follow-up time was 9.0 (0.3-18.1) years. At fifth and…
Loneliness predicts suicidal ideation and anxiety symptoms in long-term childhood cancer survivors.
2020
Abstract Background/Objective Long-term childhood cancer survivors (CCS) are at risk for adverse late effects. However, not all of them are well understood. The present study addressed loneliness, a previously under-researched mental health risk in cancer survivor populations. We assessed the prevalence of loneliness and its impact on psychological symptoms over time. Method: A registry-based sample of N = 633 adult long-term CCS underwent medical and psychological assessments and took part in a follow-up survey 2.5 years later. Psychological symptoms (somatic, anxiety, depression symptoms, and suicidal ideation) were measured using the Patient Health Questionnaire. We calculated linear reg…
Unmanned aerial system imagery and photogrammetric canopy height data in area-based estimation of forest variables
2015
In this paper we examine the feasibility of data from unmanned aerial vehicle (UAV)-borne aerial imagery in stand-level forest inventory. As airborne sensor platforms, UAVs offer advantages cost and flexibility over traditional manned aircraft in forest remote sensing applications in small areas, but they lack range and endurance in larger areas. On the other hand, advances in the processing of digital stereo photography make it possible to produce three-dimensional (3D) forest canopy data on the basis of images acquired using simple lightweight digital camera sensors. In this study, an aerial image orthomosaic and 3D photogrammetric canopy height data were derived from the images acquired …
Self-efficacy and perceived control in the prevention of cardiovascular disease
2010
Desde la Teoría de Acción Planeada (TAP), el objetivo de este trabajo es analizar si la autoeficacia y la percepción de control presentan diferencias predictivas sobre la intención y las conductas preventivas de la enfermedad cardiovascular. La muestra estuvo compuesta por 359 sujetos. Los datos han sido analizados empleando el paquete estadístico EQS 6.1. Los resultados muestran que la autoeficacia influye positiva y significativamente sobre la intención y sobre la conducta, mientras que la percepción de control influye negativa y significativamente sobre la intención de conducta, pero no sobre la conducta preventiva. Este trabajo ha mostrado la conveniencia de distinguir entre autoeficaci…
