Genetic variants of the FADS gene cluster and ELOVL gene family, colostrums LC-PUFA levels, breastfeeding, and child cognition

Introduction: Breastfeeding effects on cognition are attributed to long-chain polyunsaturated fatty acids (LC-PUFAs), but controversy persists. Genetic variation in fatty acid desaturase (FADS) and elongase (ELOVL) enzymes has been overlooked when studying the effects of LC-PUFAs supply on cognition. We aimed to: 1) to determine whether maternal genetic variants in the FADS cluster and ELOVL genes contribute to differences in LC-PUFA levels in colostrum; 2) to analyze whether these maternal variants are related to child cognition; and 3) to assess whether children's variants modify breastfeeding effects on cognition. Methods: Data come from two population-based birth cohorts (n = 400 mother-child pairs from INMA-Sabadell; and n = 340 children from INMA-Menorca). LC-PUFAs were measured in 270 colostrum samples from INMA-Sabadell. Tag SNPs were genotyped both in mothers and children (13 in the FADS cluster, 6 in ELOVL2, and 7 in ELOVL5). Child cognition was assessed at 14 mo and 4 y using the Bayley Scales of Infant Development and the McCarthy Scales of Children"s Abilities, respectively. Results: Children of mothers carrying genetic variants associated with lower FADS1 activity (regulating AA and EPA synthesis), higher FADS2 activity (regulating DHA synthesis), and with higher EPA/AA and DHA/AA ratios in colostrum showed a significant advantage in cognition at 14 mo (3.5 to 5.3 points). Not being breastfed conferred an 8- to 9-point disadvantage in cognition among children GG homozygote for rs174468 (low FADS1 activity) but not among those with the A allele. Moreover, not being breastfed resulted in a disadvantage in cognition (5 to 8 points) among children CC homozygote for rs2397142 (low ELOVL5 activity), but not among those carrying the G allele. Conclusion: Genetically determined maternal supplies of LC-PUFAs during pregnancy and lactation appear to be crucial for child cognition. Breastfeeding effects on cognition are modified by child genetic variation in fatty acid desaturase and elongase enzymes.

The construction of infant and primary school teachers’ identity during their initial professional development and first years of work (Identidoc). Summary, main results and contributions

Educators who are currently beginning their professional career at any level of the educationalsystem and who will likely have to work during the next thirty to forty years will be takingpart in the education of individuals who, with the permission of prophets and doomsayers,will live part of their lives in the 22nd century. That long but simple statement causes a bit ofvertigo as well as a good amount of reflection on the part of we educators who were trainedin the 20th century, are working in the 21st century, and are responsible for preparing peopleto build a tomorrow that is already today (Millán and Sancho, 1995). This is the starting pointof our research groups’ interest in exploring how men and women who have graduated fromteacher education programs with specializations in infant and primary education learn to beteachers, and how they establish and position themselves as teachers during their university studies and the first years of their professional life...

La Participació del psicomotricista en el joc de l'infant

This study presents a research about the participation of psicomotricist in the play with children to find out what kind of conditions improve the development of their capacitys of relathionship. The research has four parts: 1) A teoretical revision about the terms of game, social participation and relathionship; 2) A case study based on different interviews with experts, psicomotricists and the observed psicomotricist and 4 deep observations 3) The categories of analysis from the triangulation of teoretical and case study sources of information; 4) Discussion and conclusions about general actuations of the psicomotricist, about specifical actuations with the children and about psicomotricist’s believes.

De la vivència a l'experiència: la significació del medi aquàtic en el desenvolupament de l'infant

This work gets deeply into the comprehension of the aquatic medium as a significant space for the for a psychomotor intervention in the development of the children. Its starting point is a methodological pose of philosophical nature which uses phenomenology as the way for discovering. From this stand, the research sequence and process are justified. They both show an underlying attitude which has guided the whole process of turning the learning-by-experiencing the phenomena into experienced-knowledge of it. In this way the characteristic gnoseological reduction of the phenomenology has been used, while proceeding to the observation of children evolving in the water. Once the construction process of this work was established, the reduction of the amount of concepts and ideas began. This is its most characteristic process of the phenomenological research. First, an approach to the aquatic medium as a pluridimensional space has been made. Afterwards a study of the up to three years old child from a global perspective which includes the emotional, the social the cognitive and the psychomotor dimensions has been done. At last, the essence of the psychomotor as a model for the pedagogical action has been studied. From this three distinctive elements, and as a result of this research, a proposal of psychomotor intervention in the aquatic medium has been built.

The impact of eliminating a child benefit on birth timing and infant health

We study the effects of the cancellation of a sizeable child benefit in Spainon birth timing and neonatal health. In May 2010, the government announced that a2,500-euro universal "baby bonus" would stop being paid to babies born startingJanuary 1, 2011. We use detailed micro data from birth certificates from 2000 to 2011,and find that more than 2,000 families were able to anticipate the date of birth of theirbabies from (early) January 2011 to (late) December 2010 (for a total of about 10,000births a week nationally). This shifting took place in part via an increase as well as ananticipation of pre-programmed c-sections, seemingly mostly in private clinics. We findthat this shifting of birthdates resulted in a significant increase in the number ofborderline low birth weight babies, as well as a peak in neonatal mortality. The resultssuggest that announcement effects are important, and that families and healthprofessionals may face effective trade-offs when deciding on the timing (and method) ofbirth.

Multimodal Strategies in Development.Predictive Value of early simultaneosgesture-speech comination

The present study investigates the predictive value of the early appearance of simultaneous pointing-speech combinations. An experimental task was used to obtain a communicative productive sample from nineteen children at 1;0 and 1;3. Infant’s communicative productions, in combination with gaze joint engagement patterns, were analyzed in relation to different social conditions. The results show a significant effect of age and social condition on infants’ communicative productions. Gesture-speech combinations seem to work as a strong communicative resource to attract the adult’s attention in social demanding communicative contexts. Gaze joint engagement was used in combination with simultaneous pointing-speech combinations to attract adults’ attention during social demanding conditions. Finally, the use of simultaneous pointing-speech combinations at 1;0 in demanding conditions predicted greater expressive vocabulary acquisition at 1;3 and 1;6. These results indicate that the use of gesture-speech combinations may be considered a significant step towards the early integration of language components.

Emergence and development of a financial cluster: the evolution of Andorra’s banking deposits in the long-term, 1931-2007

This paper explores the origins of Andorra’s financial cluster. It shows that the free movement of currency, the protection of infant industry, and geographical concentration lie at the foundation of the cluster’s competitive advantage. Drawing on a new set of data, the paper also provides for the first time an estimate of the total deposits held by Andorra’s banks between 1931 and 2007. Based on this new information, the paper reaches the conclusion that the development of the cluster went through four distinct phases in which large companies, acting as leaders, played an important role in enhancing the cluster’s business capabilities.
