Analysing the Spanish smoke-free legislation of 2006: a new method to quantify its impact using a dynamic model.
2011
Background: There are many models that study aspects of smoking habits: the influence of price, tax, relapse time, and the effects of prohibition. There are also studies examining the effects of the Spanish smoke-free law. We wanted to build a model able to separate the effect of the law from the pre-law evolution of smoking habits. Methods: Using data from the Spanish Ministry of Health and Social Policy, we developed a dynamic model of tobacco use. The model projects the evolution over time of the number of non-smokers, smokers and ex-smokers before 2006. Then, we compared the predictions of the model with data for the years after the law came into force, 2006 and 2009. Results: We show t…
The perception of tooth whitening practices during and after orthodontic treatment: A survey of orthodontists

The Efficacy and Safety of Topiramate in the Prevention of Pediatric Migraine: An Update Meta-Analysis
2020
Background: Migraine is the most common acute primary headache in children and adolescents. In 2014, topiramate became the first preventive drug for migraine, approved by the Food and Drug Administration (FDA) for adolescents. This meta-analysis was aimed to evaluate the efficacy and safety of topiramate in the prevention of pediatric migraine.Methods: We searched the PubMed, EMBASE, Cochrane Library, and Chinese National Knowledge Infrastructure (CNKI) databases up to June 2019 for eligible randomized controlled trials (RCTs). The primary outcomes were mean migraine days per month, ≥50% reduction rate, and Pediatric Migraine Disability Assessment Scale (PedMIDAS) scores. RevMan5.3 software…
22. Administering Face-To-Face Structured Questionnaires In Tourism Research
2018
Non-sampling errors occur in all social sciences, tourism included. Apart from coverage and non-response, tourism research suffers from noteworthy measurement errors. The limitation and control of non-sampling errors plays a key role to prevent serious biases in research outputs. The entire survey design process could be based on the control and reduction of non-sampling errors. From this point of view, face-to-face interviewing represents an effective response to some common threats to data quality, particularly errors attributable to respondents and non-response.
Changes in physical activity domains during the transition out of high school: Psychosocial and environmental correlates
2015
Background:This study examined changes in multiple physical activity domains during the transition out of high school and psychosocial and environmental determinants of these changes.Methods:A 1-year prospective study was designed. The baseline sample was composed of 244 last-year high school students (58.6% female) from Valencia, Spain. Follow-up rate was 46%. Physical activity and potential determinants were measured by the Global Physical Activity Questionnaire and other evaluated scales in 2 waves.Results:Total physical activity and active commuting (AC) decreased, respectively, by 21% and 36%, only in males. At time 1, access to car/motorbike (inverse), planning/psychosocial barriers (…

Walking tourism in urban destinations: some preliminary results from a survey in Malaga with gps-based technologies
2018
Walking tourism in urban destinations can be defined as a sequence of day visits and/or a sequence of walking tours. In this work, GPS tracking data on spatio-temporal behaviour of walking tourists in Malaga are reported as case study. Malaga is a booming tourist destination characterized by a city centre, particularly suitable for a pedestrian visit. From 22nd January to 19th March 2018 for a total period of 41 days, a survey was carried out with a specific protocol: 103 interviews were conducted and 101 GPS valid tracks were collected. Walking tourists were systematically sampled, starting from the population of all tourists staying in the surveying day at some selected hotels in the city…
The Technologies of Architectural Survey: A New Comparison Based on the Tower of Sotillo de la Ribera, Burgos
2017
The paper offers an original research about the analysis and the comparison of different techniques of survey concerning the architectural field – image-based and range-based – throughout the development of the theory of errors in order to evaluate reliability and precision of the results. In particular, this analysis will be focused on the tower of the parochial Church of Santa Águeda, a building located in the small village of Sotillo de la Ribera, within the province of Burgos (Spain). The first part of this work, therefore, has been submitted to the implementation of different methodologies, from the direct survey used as a basis, to the procedure to represent graphically the results (e…
A transaction cost analysis of staffing decisions in international operations
2005
Abstract This paper analyzes staffing decisions in foreign subsidiaries from the perspective of transaction cost theory. We focus on the ex post transaction costs of the employment relation. Specifically, we look at the monitoring, bonding, maladaptation, and bargaining costs of conducting activities in specific subsidiaries in a foreign country. We hypothesize that the transaction costs of using expatriates are lower than those generated by local employees, especially in the higher managerial echelons of foreign subsidiaries, but also that costs can be reduced as individuals become more experienced. We also conjecture that ex post transaction costs are influenced by cultural differences be…
Drivers influencing the governance of inter-firm relationships in the biopharmaceutical industry: an empirical survey in the Italian context
2013
This paper focuses on factors influencing the choice of the governance form in inter-firm relationships (IFRs) between pharmaceutical and biotechnology companies. By reviewing the relevant literature on transaction cost economics, property right theory, real option and resources-based view, we located some drivers that might influence such relationships and we formulated a set of hypotheses linking them to governance forms. Such a theoretical framework has been empirically tested through a survey conducted among the Italian companies associated to Farmindustria. Empirical results provide some interesting insights on how shaping bio-pharmaceutical deals; we found that the developmental stage…
