Determinants of vaccine hesitancy and effectiveness of vaccination counseling interventions among a sample of the general population in Palermo, Ital…
2020
Counteract vaccine hesitancy is a public health priority. Main objectives of the cross-sectional study conducted were to evaluate knowledge, attitudes, and behaviors regarding vaccination issues, to estimate the prevalence of vaccine hesitancy and to estimate the effectiveness of vaccination counseling on community advocacy in a sample of general population. An anonymous validated questionnaire was administered in April 2017 at the main shopping center of Palermo and was followed by tailored vaccination counseling interventions. To estimate the effectiveness of the interventions four main connection parameters to the vaccinarsi.org website were evaluated, in the two months before and after …
Planktonic foraminifera in ODP Hole 160-963A
2006
New faunal and floral records from Ocean Drilling Project Hole 963A, resolved at ?80-year spacing, provide evidence of suborbital scale climate variability in the central Mediterranean Sea throughout Marine Isotope Stage (MIS) 5. Cold events in the central Mediterranean Sea, indicated by low abundances of warm species and high abundances of cold species, are also evident in a planktonic foraminifera paleoclimatic curve. They have been linked to NGRIP Greenland ice core “C” events and appear correlative with similar sub-millennial climate fluctuations identified in the North Atlantic region and in the Alboran Basin (Westernmost Mediterranean). Low-resolution benthic and planktonic Oxygen Iso…
Applying univariate vs. multivariate statistics to investigate therapeutic efficacy in (pre)clinical trials: A Monte Carlo simulation study on the ex…
2020
BackgroundSmall sample sizes combined with multiple correlated endpoints pose a major challenge in the statistical analysis of preclinical neurotrauma studies. The standard approach of applying univariate tests on individual response variables has the advantage of simplicity of interpretation, but it fails to account for the covariance/correlation in the data. In contrast, multivariate statistical techniques might more adequately capture the multi-dimensional pathophysiological pattern of neurotrauma and therefore provide increased sensitivity to detect treatment effects.ResultsWe systematically evaluated the performance of univariate ANOVA, Welch's ANOVA and linear mixed effects models ver…
Assessing the measurement invariance of a Latin-American Spanish translation of the Body Appreciation Scale-2 in Mexican, Argentinean, and Colombian …
2020
In order to advance in the study of positive body image among different cultures, it is important to create culturally appropriate measures. We examined the psychometric properties of a Latin-American Spanish translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), specifically assessing measurement invariance using a large sample of 3845 male and female adolescents from Argentina, Mexico, and Colombia. Participants completed the BAS-2, Eating Disorder Inventory-2, Male Body Attitude Scale and the Sociocultural Attitudes Toward Appearance Questionnaire-3. The BAS-2 had a unidimensional factor structure in each of the three samples. We confirmed the structural, met…
A Confirmatory Factor Analysis of the “Autoconcepto Forma 5” Questionnaire in Young Adults from Spain and Chile
2011
The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4,383 young adults aged 17 to 22 years (1,918 Spanish, 44%, and 2,465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish …
Long- and short-term in vitro D-dimer stability measured with INNOVANCE D-Dimer.
2009
Summary In vitro D-dimer stability in plasma is widely assumed, but has not yet been documented by systematic studies using samples covering a wide range of D-dimer. We investigated the short- and long-term stability of D-dimer in clinical citrated plasma samples with normal and pathological levels. The short-term stability was analysed by measuring D-dimer fresh, after storage of plasma for 4 hours at room temperature (RT) and after an additional 24 h storage at +2 to +8°C (n=40). Long-term stability samples (n=40) were measured fresh and after storage for 19, 25 and 36 months at ≤-60°C. The effect of repeated freezing was analysed by measuring samples (n=50) fresh and after four consecuti…
Involvement in sedentary activities and academic performance in adolescents: differences according to sociodemographic variables /Implicación en acti…
2016
AbstractThis study provides a first-time analysis of the differences in the time dedicated each day to different sedentary activities (SA) (productive, technology-based recreation and social activities) and their relation with the academic performance of Spanish adolescents according to sex, school year and socioeconomic status (SES). The sample was made up of 681 participants (50.2% girls), between 12 and 18 years old, who completed self-reported questionnaires. The likelihood of obtaining lower levels of academic success increase in adolescents who spend two or more hours on social SAs and have a lower SES. With boys, this increases further if they spend four or more hours on SAs involvin…
Future Pedagogues’ Attitudes and Knowledge about Inclusive Education in Spain: an exploratory study
2015
This article analyses the attitudes and knowledge about inclusive education among students reading Pedagogy at the University of Valencia and how these are influenced by participants’ age, gender, and which academic programme or year of study they are in. This research comprises a sample of 182 students from the degree’s four year groups, which guarantee a representativeness of 95%. The principal results indicate that attitudes towards inclusive education among students reading Pedagogy are highly positive. However, they consider the training received insufficient. Regarding the participants of the study, the analysis shows that attitudes towards inclusive education are directly related to …
Factor analysis of the Spanish Burnout Inventory among public administration employees
2014
Burnout has been recognized as an important stress-related problem. Researchers have been troubled by some of the psychometric limitations of the questionnaires developed to evaluate burnout. This study was designed to assess the factor structure of the Spanish Burnout Inventory in a sample of 548 Brazilian public administration employees. This instrument comprises 20 items distributed in four dimensions: enthusiasm toward the job (5 items), psychological exhaustion (4 items), indolence (6 items), and guilt (5 items). The factor structure was examined through confirmatory factor analysis. To assess the factorial validity of the Spanish Burnout Inventory, four alternative models were tested.…
Museums, consumers, and on‐site experiences
2010
PurposeOne conclusion is widely shared by professionals in the cultural sector: consumer motivations have changed and in particular their relations with cultural products and services. This paper seeks to analyze different trends applied to museums in order to improve the understanding of this “new” cultural audience.Design/methodology/approachFor this trend marketing analysis, seven consumer orientations have been identified (without claiming they are at all exhaustive) after an extended review over the shape of contemporary consumer habits. Besides, the authors wanted to know the opinion of the cultural managers. Each consumer orientation has been evaluated by taking a sample of French pr…
