Abstract (sommario):
Nuclear transplantation experiments in mice, reviewed elsewhere in this Symposium, have clearly demonstrated that the maternal and paternal genomes from which the embryo is formed are not functionally equivalent. The paternal genome appears to be essential for the normal development of extraembryonic tissues and the maternal genome for some stage of embryonic development. These findings provide some explanation for the observations that in mammals diploid parthenotes possessing two maternal genomes fail to survive (Markert, 1982) and that, in man, embryos with two paternal chromosome sets are

Abstract (sommario):
Some genes in mammals and flowering plants are subject to parental imprinting, a process by which differential epigenetic marks are imposed on male and female gametes so that one set of alleles is silenced on chromosomes contributed by the mother while another is silenced on paternal chromosomes. Therefore, each genome contributes a different set of active alleles to the offspring, which develop abnormally if the parental genome balance is disturbed. In Arabidopsis, seeds inheriting extra maternal genomes show distinctive phenotypes such as low weight and inhibition of mitosis in the endosperm

Abstract (sommario):
Gene expression in endosperm—a seed tissue that mediates transfer of maternal resources to offspring—is under complex epigenetic control. We show here that plant-specific RNA polymerase IV (Pol IV) mediates parental control of endosperm gene expression. Pol IV is required for the production of small interfering RNAs that typically direct DNA methylation. We compared small RNAs (sRNAs), DNA methylation, and mRNAs in Arabidopsis thaliana endosperm from heterozygotes produced by reciprocally crossing wild-type (WT) plants to Pol IV mutants. We find that maternally and paternally acting Pol IV ind

Abstract (sommario):
Modern crop breeding is in constant demand for new genetic diversity as part of the arms race with genetic gain. The elite gene pool has limited genetic variation and breeders are trying to introduce novelty from unadapted germplasm, landraces and wild relatives. For polygenic traits, currently available approaches to introgression are not ideal, as there is a demonstrable bias against exotic alleles during selection. Here, we propose a partitioned form of genomic selection, called Origin Specific Genomic Selection (OSGS), where we identify and target selection on favorable exotic alleles. Bri

AbstractUsing data from BiKS-8-18 longitudinal cohort from Bavaria and Hesse, BiKS Project 5 focused on analyzing disparate educational trajectories and outcomes among students 8-18 years old. Applying Boudon’s (1974) theoretical distinction between primary and secondary effects of social origin, this chapter summarizes the results of the influence of social origin, social relations, and intra- and extrafamilial support on different dimensions of success at school, including competencies, grades, and school self-concept. The empirical findings demonstrate the centrality of intra-family and family-school relationships before and even after the transition to secondary school and the limited opportunities in Germany to correct earlier educational decisions in secondary school. The project also involved investigating the educational decision-making processes of parents (and older students) from different social backgrounds and teachers before and after the transition from primary to secondary school to shed light on Boudon’s secondary effects of social origin. In particular, the dynamic impacts of parental aspirations and the family’s social capital, educational costs, and probabilities of success on early tracking decisions were examined and proved to be relevant, albeit not for all social groups and situations.

Abstract (sommario):
Abstract BiKS Project 7 investigates the mechanisms of disparities in educational success by migration background, especially among students from Turkey, before and after the transition from primary to secondary school in Germany. Using data from the BiKS-8-18 cohort, educational disparities between children with and without an immigrant background were empirically examined using the theoretical distinction between primary and secondary effects of social origin developed by Boudon. The results of the project show that the importance and mechanisms of primary and secondary effects on educational participation differ between students with and without immigrant background. On the one hand, the primary effect of social origin is much stronger for migrant children due to often insufficient German language skills, a lack of context-specific German cultural capital, and familial cultural capital that has lost at least some of its value due to migration. In contrast, the secondary effects of social origin are much weaker for migrant children: When children’s academic performance is controlled for, migrant children have a higher transition rate to upper secondary school, regardless of their social class of origin. Thus, migrant parents’ realization of more ambitious educational goals for their children (small secondary effect) is primarily hampered by their children’s poorer academic performance (strong primary effect).

Abstract (sommario):
AbstractThis chapter asks how barriers to equal participation in adult education play out differently between (a) men and women and (b) women from different class and ethnic backgrounds. European Social Survey and Adult Education Survey data analyses confirm that low social origin is a significant barrier. Other socio-economic and socio-demographic characteristics can also act as barriers. The chapter draws attention to intersectionality: multiple simultaneous disadvantages, including gender (for women), social origin (for adults whose parents have basic or lower levels of education), and having an ethnic minority or migrant background. Women are less likely to receive financial support from their employer, though more likely to do so from public institutions. Ethnic minority status has a stronger negative effect for women than for men. Mediterranean and post-socialist welfare regimes reduce the effects of intersectionality less than social-democratic regimes.

Abstract (sommario):
AbstractWhether the children of immigrant populations, including refugees, integrate into the host society is a key challenge facing all countries with large immigrant populations. In Australia, this is crucial given rising numbers and anxieties over refugee settlement in recent decades. Forced migration and displacement due to violence, persecution, or natural disasters with families undertaking perilous journeys fleeing their homes often could mean a turning point and at the same time a stressful event that may have severe negative psychosocial and long-term effects. This can be particularly acute among refugee children, who are typically the least prepared to migrate, have experienced hardship associated with violence and persecution, and must grow up in a new country. From a life course perspective, the integration and wellbeing of refugee children is shaped by the timing and context of migration, including their age at migration and country of origin. In this chapter we draw on longitudinal data from Building a New Life in Australia (BNLA) to offer new evidence in our understanding of the integration and wellbeing of refugee children in Australia and policy recommendations to address the social disadvantages facing this population. Our findings indicate that refugee children are outperforming their parents, making intergenerational progress. However, we find some major differences by gender and national origin across a range of outcomes.

Abstract (sommario):
Abstract With a recent trend in increased infill well development in the Midland basin and other unconventional plays, it has been shown that depletion has a significant impact on hydraulic fracture propagation. This is largely because production drawdown causes in-situ stress changes, resulting in asymmetric fracture growth toward the depleted regions. In turn, this can have a negative impact on production capacity. For the initial part of this study, an infill child well was drilled and completed adjacent to a parent well that had been producing for two years. Due to drilling difficulties, t

Abstract (sommario):
Shape memory alloys take place in a class of advanced smart materials by exhibiting a peculiar property called shape memory effect. This phenomenon is initiated with thermomechanical treatments on cooling and deformation and performed thermally on heating and cooling, with which shape of materials cycles between original and deformed shapes in reversible way. Therefore, this behavior can be called Thermoelasticity. This is plastic deformation with which strain energy is stored in the material and releases on heating by recovering original shape. This phenomenon is based on thermomechanical tra

Chronic diseases affect the quality of life of families of sick people on the level of their physical, economic, mental, and subjective well-being. The aim of the paper is two-folded: a) to determine the economic and social consequences of the child's illness for families and b) to identify the factors that may influence the origin and development of asthma in the child population. The data come from a survey we carried out on a sample of parents with children who are treated in the Children's Speleotherapy Sanatorium in Ostrov near Macocha (a total sample of 201 respondents).

Abstract (sommario):
The objective of this paper is to better understand peer popularity during adolescence and detect discrimination. The paper subsequently explores how student's characteristics affect their popularity. It is found that physically attractive students and with high academic performance are highly ranked by their peers, but the former effect is only significant in mixed schools, suggesting that is primarily driven by mating. Other traits, such as skin color, nationality and parental socioeconomic background do not affect peer popularity, although ethnic origin and parental education are statistica

Abstract (sommario):
Chiasma is the point of crossing over or site where the exchange of genetic material takes place between two homologous, non-sister chromatids. The crossover occurs in the pachytene stage, however, it is observed in the diplotene stage of meiosis-I[2]. The cross-over between the two homologs also creates a new combination of parental genes, forming recombinants. The recombination of the genes causes variation in the population and exert a profound effect on genomic diversity and evolution. Meiotic recombination and variation in the population have been a concern for scientists to understand th

Abstract (sommario):
Background to the topic: In previous works we have shown that Arabidopsis and tomato over-expressing H+-pyrophosphatase show increased tolerance to drought imposed by withholding irrigation of young plants in pots (Park et al. 2005). In addition, young tobacco plants over-expressing fatty acid desaturase 3 (OEX-FAD3) also showed increasing tolerance to drought stress (Zhang et al 2005), and similarly OEX-FAD3 young tomato plants (unpublished data from ARO), hence raising the possibility that pyramiding the two could further improve drought tolerance in tomato.

Abstract (sommario):
Heterosis, the enigmatic phenomenon in which whole genome heterozygous hybrids demonstrate superior fitness compared to their homozygous parents, is the main cornerstone of modern crop plant breeding. One explanation for this non-additive inheritance of hybrids is interaction of alleles within the same locus. This proposal aims at screening, identifying and investigating heterosis trait loci (HTL) for different yield traits by implementing a novel integrated mapping approach in Sorghum bicolor as a model for other crop plants.

Abstract (sommario):
Arabidopsis mutants that we have isolated, encode for fertilization-independent endosperm (fie), fertilization-independent seed2 (fis2) and medea (mea) genes, act in the female gametophyte and allow endosperm to develop without fertilization when mutated. We cloned the FIE and MEA genes and showed that they encode WD and SET domain polycomb (Pc G) proteins, respectively. Homologous proteins of FIE and MEA in other organisms are known to regulate gene transcription by modulating chromatin structure. Based on our results, we proposed a model whereby both FIE and MEA interact to suppress transcri
