Over the past decade there has been increasing interest in the relationships between youth policy making, youth research and practice with and by young people. Sometimes referred to as the ‘magic triangle’ that has the potential to strengthen all corners if there are effective lines of communication and dialogue, there are also reservations about the connections between the ‘corners’. The interest in ‘evidence-based practice’, for example, is not always matched by a commitment to ‘practice-based evidence’. This book, drawing on contributions at an EU seminar during the Luxembourg presidency, debates the links between research, policy and practice, and their roles in knowledge production, analysis and dissemination as the engine for more effective and relevant youth policy in Europe.

Our research project aims to inquire whether there are any specificities in female entrepreneurship and if necessary to point them out. Our study will take different angles: first, the women-owned societies’ profile, second the women entrepreneurs’ business processes and finally the women entrepreneurs’ profile. Tools will be shaped in accordance with this analysis, in order to increase the awareness of women and intermediates of business creation and development. [less ▲]

Increasingly aware of the importance of active lifestyles, many people intend to exercise more. One of the main challenges is to translate exercise intentions into actual exercise behaviour, the so-called intention-behaviour gap. To investigate barriers and enablers that affect this gap, we conducted a 7-day diary study with 16 participants. In this study, participants indicated what their exercise intentions and behaviour were per day, and whether and why they changed retrospectively during the day. Through the diary study, we gain insights into (i) the intention-behaviour interplay, and (ii) the experienced barriers and enablers that influence this interplay throughout the day. Based on the findings, we contribute new implications for design in supporting people translating their intentions into exercise behaviour, and propose three design concepts as examples. In these, the focus is on positively influencing the interplay of enablers and barriers of exercising and how these can be exemplified through design. [less ▲]

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms, both of which are affected by the presence of a diaspora abroad. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in another one) affect the size and human-capital structure of current bilateral migration flows. Our analysis exploits a bilateral data set on international migration by educational attainment from 195 countries to 30 OECD countries in 1990 and 2000. Based on simple microfoundations and controlling for various determinants of migration, we found that diasporas increase migration flows and lower their average educational level. Interestingly, diasporas explain majority of the variability of migration flows and selection. This suggests that, without changing the generosity of family reunion programs, education-based selection rules are likely to have moderate impact. Our results are highly robust to the econometric techniques, accounting for the large proportion of zeros and endogeneity problems. [less ▲]

BACKGROUND: RNA silencing is a common term for pathways utilizing small RNAs as sequence-specific guides to repress gene expression. Components of the RNA silencing machinery are involved in different aspects of chromatin function in numerous organisms. However, association of RNA silencing with chromatin in mammalian cells remains unclear. METHODOLOGY/PRINCIPAL FINDINGS: Immunostaining of mitotic chromosomes with antibodies visualizing either endogenous or ectopically expressed Dicer in mammalian cells revealed association of the protein with ribosomal DNA (rDNA) repeats. Chromatin immunoprecipitations and bisulfite sequencing experiments indicated that Dicer is associated with transcribed regions of both active and silenced genes in rDNA arrays of interphase chromosomes. Metabolic labeling of the mouse embryonic stem (ES) cells lacking Dicer did not reveal apparent defect in rRNA biogenesis though pre-rRNA synthesis in these cells was decreased, likely as a consequence of their slower growth caused by the loss of miRNAs. We analyzed in detail chromatin structure of rDNA but did not find any epigenetic changes at rDNA loci in Dicer(-/-) ES cells. Instead, we found that rDNA methylation is rather low in primary tissues, contrasting with rDNA methylation patterns in transformed cell lines. CONCLUSION/SIGNIFICANCE: We found that Dicer, a key component of RNA silencing pathways, can be detected in association with rDNA chromatin in mammalian cells. The role of this particular localization of Dicer is not readily apparent since the enzyme is associated with rDNA genes regardless of their transcriptional activity. However, localization of Dicer to the transcribed region suggests that transcription may contribute to the Dicer deposition at rDNA chromatin. We hypothesize that Dicer functions in maintaining integrity of rDNA arrays. [less ▲]
