Satisfação Profissional no Docente Dominicano: Antecedentes Profissionais
2019
Resumen La satisfacción laboral del colectivo docente ha sido estudiada desde diversas perspectivas, debido a los importantes efectos que esta puede tener tanto a nivel económico como a nivel organizacional. La muestra empleada en este trabajo se compone de 978 docentes dominicanos, y fue obtenida mediante un muestreo estratificado, y, por tanto, representativo de la población. En este estudio se examina un modelo de ecuaciones estructurales en el cual el contexto de trabajo y las condiciones laborales afectan el burnout y el engagement de los profesores. A su vez, se plantea que burnout y engagement afectan la satisfacción laboral docente. El modelo ajustó a los datos: x2(223)= 1089.9, p<.…
Tensions and Paradoxes of Scaling Up : A Critical Reflection on Physical Activity Promotion
2022
Background: Achieving system-level, sustainable ‘scale-up’ of interventions is the epitome of successful translation of evidence-based approaches in population health. In physical activity promotion, few evidence-based interventions reach implementation at scale or become embedded within systems for sustainable health impact. This is despite the vast published literature describing efficacy studies of small-scale physical activity interventions. Research into physical activity scale-up (through case-study analysis; evaluations of scale-up processes in implementation trials; and mapping the processes, strategies, and principles for scale-up) has identified barriers and facilitato…
Recalled parental rearing style, self-esteem, and psychopathological symptoms in the general population
2020
The enduring impact of perceived parental behavior on self-esteem as well as anxiety and depression in adults is still unknown. In a large random route sample (age range 18?92), 4,747 subjects were asked to complete questionnaires about recalled parental rearing, selfesteem, anxiety, and depression. Structural equation modeling was used, and the data from the mother and the father version of the FEE (a questionnaire for recalled parental rearing) were analyzed separately. A model proposing that self-esteem mediates the relationship between parental behavior and psychopathological symptoms fits the data rather well (CFI = .95, RMSEA = .05, TLI = .94). Hence, the recalled authoritative parent…
Motivational Regulations Across the Stages of Change for Exercise in the General Population of Monterrey (Mexico)
2018
Few studies have examined exercise adherence in the Mexican population using self-determination theory proposals and the stages of change model. The objectives of this study were:(a) to translate and adapt the Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3) to Mexican Spanish and examine its internal consistency and factorial structure (six dimensions); and (b) to analyse variations in behavioral regulations using the stages of change model. This study included 530 participants between 11 and 76 years old who lived in the metropolitan area of the city of Monterrey, Nuevo Leon, Mexico. The Mexican version of the BREQ-3 presented an acceptable six-factor model that agrees with the …
COVID-19 in Severe Asthma Network in Italy (SANI) patients: Clinical features, impact of comorbidities and treatments
2020
To the Editor Since the end of February 2020 Italy, first non- Asian Country, has reported an ever increasing number of COronaVIrus Disease 19 (COVID-19) patients, which has reached over 200,000 confirmed Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) infected subjects and resulted in more than 34000 deaths (data updated to June 19th, 20201).Patients with asthma are potentially more severely affected by by SARS-CoV-2 infection 2 and it is well established that respiratory viral infections are associated with severe adverse outcomes in patients with asthma, including increased risk of asthma exacerbation episodes 3. Nonetheless, according to the epidemiological studies publishe…
Data from: Daphnia females adjust sex allocation in response to current sex ratio and density
2019
Cyclical parthenogenesis presents an interesting challenge for the study of sex allocation, as individuals’ allocation decisions involve both the choice between sexual and asexual reproduction, and the choice between sons and daughters. Male production is therefore expected to depend on ecological and evolutionary drivers of overall investment in sex, and those influencing male reproductive value during sexual periods. We manipulated experimental populations, and made repeated observations of natural populations over their growing season, to disentangle effects of population density and the timing of sex from effects of adult sex ratio on sex allocation in cyclically parthenogenetic Daphnia…
Sex differences in correlates of intermediate phenotypes and prevalent cardiovascular disease in the general population
2015
Background: There are marked sex differences in cardiovascular disease (CVD) manifestation. It is largely unknown how the distribution of CVD risk factors or intermediate phenotypes explain sex-specific differences. Methods and Results: In 5000 individuals of the population-based Gutenberg Health Study, mean age 55 ± 11 years, 51% males, we examined sex-specific associations of classical CVD risk factors with intima-media thickness, ankle-brachial index, flow-mediated dilation, peripheral arterial tonometry, echocardiographic, and electrocardiographic variables. Intermediate cardiovascular phenotypes were related to prevalent CVD [coronary artery disease, heart failure, stroke, myocardial i…
Genetic variability of the blue and red shrimp Aristeus antennatus in the Western Mediterranean Sea inferred by DNA microsatellite loci
2012
Genetic variation at eight microsatellite loci was studied in nine populations of the blue and red shrimp Aristeus antennatus to investigate whether distinct stocks are present in the Western Mediterranean Sea. A high level of gene flow and no evidence of genetic partitioning were discovered. No significant variation was found (FST = 0.00673, P-value = 0.067) even when shrimps from exploited and those from deep-water unexploited grounds were compared. No evidence of reduction or expansion of population size in the recent past was found, as indicated by the bottleneck and interlocus g-tests. Our results are consistent with previous studies using mitochondrial gene methods and allozymes, indi…
Genomic diversity and population structure analysis reveal few genetic differences among Ethiopian indigenous sheep populations
2017
African sheep, like other domestic sheep, are domesticated from the Asiatic mouflon (Ovis orientalis). They entered the continent through the North and the Horn of Africa regions following maritime and terrestrial trading routes. Ethiopia is one of the main entry points of various plant and animal domesticates into Africa. It is characterised by diverse agro-ecologies, ancient human ethnic diversity and the presence of indigenous sheep breeds/populations of unprecedented morphological diversity (e.g. tail types). Here, we investigate the genome diversity and population structure of 146 unrelated animals from 11 Ethiopian indigenous sheep populations. DNA was extracted from ear tissue punche…
Slow Populations and Tourism
2013
Our initial perspective is that the dynamics of territories and cities/towns that are tourist resorts (or aspire to being one) can be analysed from the point of view of the ‘population’ concept, dear to a certain trend in socio-spatial analysis. Our chapter concentrates particularly on those who, by need or will, pass through places without their own vehicle, but using collective or public transport, as well as walking or cycling, rather than by walker or wheelchair. These ‘slow populations’ enter into a relation with the places they visit or stay at, with the people who live there and the other tourists, following certain methods of which we suggest a sort of classification, aimed at a bet…
