Parent–child relationships and adolescents’ life satisfaction across the first decade of the new millennium

This is the peer reviewed version of the following article: Antonia Jiménez-Iglesias, Irene GarcÍa-Moya, and Carmen Moreno, ‘Parent–Child Relationships and Adolescents' Life Satisfaction Across the First Decade of the New Millennium’, Family Relations, Vol. 66 (3): 512-526, July 2017, which has been published in final form at: https://doi.org/10.1111/fare.12249.

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Objective: To examine whether changes occurred in parent–child relationships (maternal and paternal affection, ease of communication with the mother and father, maternal and paternal knowledge, and family activities) between 2002 and 2010 in boys and girls and to examine the contributions of these family dimensions to life satisfaction. Background: Although parent–child relationships may be affected by social change, there are few investigations of change in parent–child relationships over time. Method: The sample consisted of 46,593 adolescents between 11 to 18 years of age who participated in the 2002, 2006, or 2010 editions of the Health Behaviour in School-aged Children (HBSC) study in Spain. Trend analysis including univariate analyses of variance (ANOVAs) and factorial ANOVAs were conducted separately for boys and girls, and effect size tests were calculated. Results: Communication with fathers and family activities statistically increased across HBSC editions and parent–child relationships were positively associated with life satisfaction across the examined period. Conclusion: There were small positive changes in some family dimensions, and some of them were increasingly important for adolescent life satisfaction over time. Implications: Interventions for strengthening parent-child relationships and promoting adolescent well-being should include mothers and fathers and emphasize affection, communication, and family activities.Peer reviewedFinal Accepted Versio

Global Chromatin Domain Organization of the Drosophila Genome

In eukaryotes, neighboring genes can be packaged together in specific chromatin structures that ensure their coordinated expression. Examples of such multi-gene chromatin domains are well-documented, but a global view of the chromatin organization of eukaryotic genomes is lacking. To systematically identify multi-gene chromatin domains, we constructed a compendium of genome-scale binding maps for a broad panel of chromatin-associated proteins in Drosophila melanogaster. Next, we computationally analyzed this compendium for evidence of multi-gene chromatin domains using a novel statistical segmentation algorithm. We find that at least 50% of all fly genes are organized into chromatin domains, which often consist of dozens of genes. The domains are characterized by various known and novel combinations of chromatin proteins. The genes in many of the domains are coregulated during development and tend to have similar biological functions. Furthermore, during evolution fewer chromosomal rearrangements occur inside chromatin domains than outside domains. Our results indicate that a substantial portion of the Drosophila genome is packaged into functionally coherent, multi-gene chromatin domains. This has broad mechanistic implications for gene regulation and genome evolution

The application of omics in ruminant production: a review in the tropical and sub-tropical animal production context

The demand for animal products (e.g. dairy and beef) in tropical regions is expected to increase in parallel with the public demand for sustainable practices, due to factors such as population growth and climate change. The necessity to increase animal production output must be achieved with better management and production technologies. For this to happen, novel research methodologies, animal selection and postgenomic tools play a pivotal role. Indeed, improving breeder selection programs, the quality of meat and dairy products as well as animal health will contribute to higher sustainability and productivity. This would surely benefit regions where resource quality and quantity are increasingly unstable, and research is still very incipient, which is the case of many regions in the tropics. The purpose of this review is to demonstrate how omics-based approaches play a major role in animal science, particularly concerning ruminant production systems and research associated to the tropics and developing countriesinfo:eu-repo/semantics/acceptedVersio
