Field rules and bias in random surveys with quota samples : an assessment of CIS surveys
2018
Surveys applying quota sampling in their final step are widely used in opinion and market research all over the world. This is also the case in Spain, where the surveys carried out by CIS (a public institution for sociological research supported by the government) have become a point of reference. The rules used by CIS to select individuals within quotas, however, could be improved as they lead to biases in age distributions. Analysing more than 545,000 responses collected in the 220 monthly barometers conducted between 1997 and 2016 by CIS, we compare the empirical distributions of the barometers with the expected distributions from the sample design and/or target populations. Among other …
Property and cross-border couples from the perspective of European regulation
2021
The family property regimes constitute a relevant sector of the EU regulatory framework strongly connected with fundamental rights policies. Family property offers specific issues which need to balance individual rights with general interests, especially in matter of real estate property. The fragmentation of the discipline in EU Family law, the diversity of the domestic rules regarding rights in rem requires a large use of flexibility from EU legislator and EU legal professionals. The discipline provides by EU Regulations 1103 and 1104/2016 could be an interesting example to manage cross-border couple?s interests: the principles of universality and unity have to be used appropriately and, …
Stable isotopes covering 96-7 ka BP from stalagmite CM (Santo Tomas Cave, Cuba)
2020
We present a new speleothem trace element and stable isotope record, which extends previous paleoclimate evidence from Cuban speleothems to the last 96 ka. Stable isotope samples were micromilled at a resolution of 0.10-0.33mm, and measured using an IRMS equipped with a Gasbench. Line scans of Element/Calcium ratios of the speleothem were measured by laser ablation ICPMS and were reduced to the resolution of the stable isotope records.
Updated measurement of the τ lepton lifetime
1997
A new measurement of the mean lifetime of the tau lepton is presented. Three different analysis methods are applied to a sample of 90000 tau pairs, collected in 1993 and 1994 with the ALEPH detector at LEP. The average of this measurement and those previously published by ALEPH is tau_tau = 290.1 +- 1.5 +- 1.1 fs.
The relationship between organizational interdependency and additionality obtained from innovation ecosystem participation
2019
Abstract Despite the increased interest in innovation ecosystems, few studies have assessed the extent to which the proclaimed benefits from participating in such ecosystems also occur, and under which circumstances they do occur. Uniting the literature on organizational interdependence and social exchange theory, we assess the behavioral and output additionality obtained by innovation ecosystem participants. In doing so, we build upon a sample of 473 innovative Finnish companies, of which 312 participated in an innovation ecosystem. We find a significantly positive relationship between organizational interdependence and output additionality, and find that this relationship is mediated by b…
Epidemiology of eating disorders in Latin America: a systematic review and meta-analysis.
2016
Purpose of reviewEating disorders are currently not considered to be limited to Western culture. We systematically reviewed the existing literature on the prevalence of eating disorders in Latin America.Recent findingsOf 1583 records screened, 17 studies from Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela were included in the analysis. Most studies reported point-prevalence rates and only three studies provided lifetime and 12-month prevalence rates. We found a mean point-prevalence rate of 0.1% for anorexia nervosa, 1.16% for bulimia nervosa, and 3.53% for binge-eating disorder (BED) in the general population. Heterogeneity for bulimia nervosa and BED was large. This meta-analys…
Diagnostic utility of new short versions of AUDIT to detect binge drinking in undergraduate students
2021
ABSTRACT This study examines the usefulness of two AUDIT adaptations with a sample of 907 undergraduate alcohol users. On the one hand, it includes the AR2i that encompasses revised A2r and A3r consumption items, and on the other hand—in addition to the two former items—the inclusion of items 4, 8, and 9, which evaluate consequences. The results indicate that both adaptations identify BD more precisely than the traditional scales (AUDIT and AUDIT-C), but the usefulness of each will depend on the clinical purpose they are given. In environments where time is a key factor in detecting high-risk consumption it will be more appropriate to use AR2i, which evaluates the pattern of con…
Personal variables, motivation and avoidance learning strategies in undergraduate students
2014
Abstract This study examines the relationships among students' personal variables, their initial motivation and the avoidance learning strategies they used during the teaching/learning process followed in the Educational Psychology subject matter. The sample comprised 195 Spanish undergraduate students who studied Educational Psychology. A questionnaire was administered at the beginning of the academic year to measure students' personal variables and their initial motivation, while another was administered at the end of the academic year to measure students' involvement in their learning process through the avoidance strategies they used. The data analysis was done by using structural equat…
Toward adjustment profiles for lower secondary student-athletes in the Finnish dual career context: A mixed-methods approach
2022
Engagement, burnout, and experiences are central concepts for understanding student-athlete adjustment in a dual career (DC) environment. As part of a larger 3-year, lower secondary sports schools pilot project, the aim of this study was to examine student-athletes’ DC adjustment in Finnish lower secondary sports schools at the end of the second academic year. By combining quantitative and qualitative methods, we sought to (a) identify adjustment profiles among student-athletes based on measures of engagement and burnout in school and sport and (b) to extract experiences that describe the distribution of student-athletes in the profiles. A latent profile analysis using questionnaire data fr…
Audit and Earnings Management in Spanish SMEs
2016
Abstract Evidence about the relation between earnings management and voluntary audits is scarce, and there is no research about the effectiveness of mandatory audits to improve earnings quality. Using a sample of Spanish SMEs, where some companies are mandatorily audited and some are exempt from audit, we examine if audits, either mandatory or voluntary, help to improve accounting quality by constraining earnings management. We also examine differences between voluntary and mandatory audits, as well as the role of Big 4 and Middle-Tier auditors. After controlling for other characteristics that affect earnings management, we find that audited companies have lower absolute discretionary accru…
