In Vitro Evaluation of the Biological Effects of ACTIVA Kids BioACTIVE Restorative, Ionolux, and Riva Light Cure on Human Dental Pulp Stem Cells
2019
This study aimed to analyze the biological effects of three new bioactive materials on cell survival, migration, morphology, and attachment in vitro. ACTIVA Kids BioACTIVE Restorative (Pulpdent, Watertown, MA, USA) (Activa), Ionolux (Voco, Cuxhaven, Germany), and Riva Light Cure UV (SDI, Bayswater, Australia) (Riva) were handled and conditioned with a serum-free culture medium. Stem cells from human dental pulp (hDPSCs) were exposed to material extracts, and metabolic activity, cell migration, and cell morphology were evaluated. Cell adhesion to the different materials was analyzed by scanning electron microscopy (SEM). The chemical composition of the materials was evaluated by energy-dispe…
Later-life depressive symptoms and anxiety attacks in displaced and nondisplaced populations
2021
Abstract Background Forced displacement has been suggested as a potential cause for depression and anxiety in later life. Little research has been done on the influence of the host country's socio-political system. Here we examine whether the later-life effects of displacement on mental health (i.e. depressive symptoms and anxiety attacks) differ between socio-political contexts. We hypothesized that between-group differences (displaced vs. nondisplaced) in self-rated depression scores and frequencies of anxiety attacks are more pronounced in East versus West German populations. Methods Datasets from three representative nationwide surveys (2002, 2003, 2007) were analyzed; study participant…
Income Differences in Regions of Latvia – Problems and Challenges
2019
Income differences in regions of Latvia is becoming a greater problem for families as there are made decisions for emigration, for municipalities as there are significant reductions in tax (income and property) payers and for entrepreneurs as there are less customers for their products and services: those aspects are on great importance but not enough researched and discussed in academic research. Purpose of the study is to analyse income differences in the regions of Latvia. The tasks of the study: 1 to review theoretical background of income differences in context of regional development; 2 to review existing research of income differences in the regions in EU; 3 to analyse problems of in…
“Black Italia. Contemporary Migrant Writers from Africa”
2009
Through the centuries, historical and fictional characters of African descent have been an integral part of Italian culture at large – from Hannibal to Othello. Yet their presence, in history as much as in the arts, has often been marginalized, or considered episodic, if not entirely overlooked by Italy’s dominant discourse. The recent arrival of a plethora of migrants from the four corners of the world, many of whom from African countries, has urged Italians to recuperate their African past as an essential, and often problematic, component of their national identity. Yet historical sources appear fragmentary and often interpolated. How to re-compose the neglected African Italian heritage? …
Ķīna un ķīniešu migrācija ārzemēs
2019
Migrācija kā viena no globalizācijas procesa izpausmēm ir kļuvusi par nozīmīgu parādību divdesmitajā gadsimtā. Ta ietekmē dažādu pasaules valstu politisko, sociālekonomisko un demogrāfisko attīstību, starpvalstu mijiedarbības un integrācijas procesus starptautiskajā sabiedrībā. Tajā pašā laikā migrācijas pieaugums izraisa drošības un noziedzības problēmu pasliktināšanas nelegālās migrācijas, cilvēku tirdzniecības, ksenofobijas un terorisma veidā. Tas viss pievērš lielu uzmanību starptautiskajām organizācijām, valstu valdībām, zinātnieku aprindām un plašai sabiedrībai. Ķīnas migrācijai kā nozīmīgai demogrāfiskajai parādībai ir ietekme uz saņēmējvalstīm, ieviešot izmaiņas dzimumu un demogrāfi…
Grèce : un monde de migrants
2015
International audience; Le monde grec, pas plus que le nôtre, ne fut un monde stable. La mythologie comme l'archéologie attestent de mouvements de populations en tous sens autour de la Méditerranée et de la mer Noire. Colons à la recherche de terre, exilés politiques, réfugiés économiques, aventuriers : le monde grec est un monde de migrants qui, libres ou contraints, se sont déplacés tout autour de la Méditerranée. La figure du migrant tient une place de choix dans la mythologie. Avant de se faire reconnaître comme un dieu et de recevoir un culte, Dionysos emprunte toujours le costume du migrant. Dans Les Bacchantes d'Euripide, lorsqu'il arrive à Thèbes, il n'est pour Penthée, le maître de…
A Next‐Generation Air‐Stable Palladium(I) Dimer Enables Olefin Migration and Selective C−C Coupling in Air
2020
Abstract We report a new air‐stable PdI dimer, [Pd(μ‐I)(PCy2 tBu)]2, which triggers E‐selective olefin migration to enamides and styrene derivatives in the presence of multiple functional groups and with complete tolerance of air. The same dimer also triggers extremely rapid C−C coupling (alkylation and arylation) at room temperature in a modular and triply selective fashion of aromatic C−Br, C−OTf/OFs, and C−Cl bonds in poly(pseudo)halogenated arenes, displaying superior activity over previous PdI dimer generations for substrates that bear substituents ortho to C−OTf.

Les jeunes issus de l'immigration. De l'enseignement supérieur au marché du travail
2004
04038http://www.cereq.fr/pdf/b205.pdf; Souvent d'origine sociale défavorisée, les jeunes issus de l'immigration sont proportionnellement moins nombreux que les autres à poursuivre leurs études après le baccalauréat. Même lorsque tel est le cas, leur passage par l'enseignement supérieur ne parvient pas toujours à gommer le poids de leur origine, en particulier lorsqu'ils sont issus de l'immigration nord-africaine. Plus souvent confrontés au chômage, à la précarité de l'emploi, les jeunes d'origine maghrébine, et notamment les jeunes femmes, ont en effet plus de difficultés à entrer dans la vie active. Pour accéder à leur premier emploi, ils ont fréquemment recours à l'intérim, au travail sai…
