During the Covid-Crisis, stereotypes of older adults as helpless and vulnerable were spread, and intergenerational conflict was stirred more or less openly. We thus focused on perceived ageism during the crisis and its effects on well-being and health of older adults. Since views on aging are multifaceted and can be both, risk and resource for individual development, we assessed people’s self-perceptions of aging (SPA) as social loss, continued growth and physical decline and subjective age (SA). We hypothesized that people with SPA of social loss and physical decline would be more susceptible to negative effects of perceived ageism, whereas those with SPA of continued growth and younger SA would be less affected. NT1 = 611 community-dwelling adults aged 60 – 98 (Mage = 69.92 years) were recruited in June 2020 online and via phone in Luxembourg. In September 2020, participants will be contacted again for a follow-up. Analyses with cross-sectional data show that participants who felt more discriminated reported lower life satisfaction after the onset of the crisis (r = -.35) and worse subjective health (r = -.14). SPA of social loss and higher SA increased the negative effect of ageism on well-being (beta = -.57) and subjective health (beta = -.53), respectively. Our results point to mid- and long-term consequences of age discriminatory and stereotype-based crisis communication for the well-being of older adults and the importance of individual SPA in critical situations.

The investigation of what enables societies and individuals to age well remains one of the greatest challenges of our time. Views on aging are a decisive factor in this process, and thus, improving their understanding through cross-cultural research is of utmost importance. In the current review, we address the role of socio-ecological variables and cultural values and beliefs when investigating country differences in what people think about older persons and getting old themselves. Several complexities are introduced in terms of a differentiated conceptualization of views on aging that takes life domains and normative prescriptions into account, and also in terms of a differentiated and extended view on the factors through which societal and cultural aspects and views on aging mutually influence each other. We propose that an encompassing, lifespan framework on views on aging enhances our understanding of aging well in different cultural and societal contexts. [less ▲]

Over the past 20 years, research on views on aging has substantiated their importance for successful development and sustained quality of life over the full length of the life span. However, a deep understanding of the origins of views on aging and the underlying processes of their lifespan development and manifestation is lacking. Since 2017, the scientific network “Images of Aging” funded by the German Research Foundation (http://www.health.uni-konstanz.de/images-of-aging) assembles national and international renowned experts in the field. The network engages in empirical clarifications on both the distinctness and validity of the construct (contribution of Klusmann et al.) as well as in critically reviewing terminology and measures of views on aging (contribution of Notthoff et al.). The network aims to help clarifying the dynamic interplay of determinants and outcomes in the context of health (contribution of Wolff et al.) as well as disentangling intra- and intergenerational stereotypic perceptions (contribution of Kornadt et al.). Both of these are understudied issues with highly practical implications for two of the largest demographic challenges: shaping the coexistence of generations as well as providing adequate health care supply. Integrating both pertinent theoretical approaches and empirical findings the network regards views on aging under a lifespan perspective. Recently, it suggested three core principles of views on aging regarding lifelong bio-psycho-social development, their multidimensional nature, and their impact across life. These considerations provide a background for an integrative discussion of the symposium’s contributions. [less ▲]

95 058 personnes vivaient dans la capitale à la date du recensement (1er février 2011), soit 24.0% de plus qu’en 2001. Avec ce taux, la croissance démographique de la Ville de Luxembourg a dépassé celle de sa périphérie, c’est-à-dire Luxembourg-Campagne1 (dont la population a augmenté de 17.0% de 2001 à 2011), mais aussi celle de l’ensemble du pays (+16.6%). Luxembourg-Ville et Luxembourg-Campagne représentaient ensemble 29.6% des habitants du pays en 2011, contre 28.4% en 2001. Seul un tiers des habitants de la capitale sont des Luxembourgeois (35.1%), suivis par les Français (14.3%) et les Portugais (14.1%). La sur-face moyenne des logements dans la Ville de Luxembourg est de 105.5 m² et se situe largement en-dessous de la surface moyenne des logements dans l’ensemble du pays (129.9 m²) et dans la périphérie de la Ville (144.8 m² à Luxembourg-Campagne). Cependant, la taille moyenne des ménages à Luxembourg-Ville (1.94 personnes par ménage) est également plus réduite que dans l’ensemble du pays (2.41) et à Luxembourg-Cam-pagne (2.47). Avec 26.4%, la part des habitants vivant seuls est près de deux fois plus élevée dans la capitale que dans le pays pris dans son en-semble (13.8%). 40.3% des habitants de la capitale vivent dans des ménages constitués par un couple avec enfant(s), alors que dans le pays le pourcen-tage correspondant atteint les 51.8%. Les habitants de la Ville de Luxembourg ont souvent des niveaux d‘éducation plus élevés que dans le reste du pays. La part des personnes ayant un diplôme de type « master » ou un doctorat (33.9%) est plus de deux fois plus élevé que dans le pays en général (14.8%). En revanche, les niveaux d’éducation faibles ou moyens sont moins fréquents dans la capitale que dans le reste du pays. [less ▲]

Le programme de recherche Reconstructions littéraires françaises et francophones des espaces sociopolitiques, historiques et scientifiques de l’extrême contemporain a réuni des chercheurs européens dont les travaux, présentés ici, sont entrés en dialogue au sujet de la catégorie de l’espace, en étroite relation avec la géographie, l’histoire, les sciences sociales et politiques, et enfin les sciences cognitives et la cybernétique. L’espace est soumis aux tensions des difficiles premières années du XXIe siècle (guerres, peurs et fantasmes « terroristes », etc.), de surcroît marquées par une crise économico-financière sans précédent depuis 1929, de telle sorte que les groupes sociaux et les individus s’inscrivent dans des situations très nouvelles dans lesquelles se trouvent réactivés soupçons et défiances à l’égard des institutions politiques et de leurs administrations. Aucun domaine n’est épargné, qu’il s’agisse de l’éducation, de la recherche scientifique ou des activités de diffusion de l’information. Ce volume explore et analyse la création, essentiellement romanesque, de l’extrême contemporain, où l’espace s’impose avec force, comme en témoigne le rôle rempli par les lieux archétypiques de la « surmodernité » – prisons, usines, périphéries urbaines, voire centrales nucléaires, ensemble de lieux « sans qualités apparentes ». C’est parce que la littérature est à la fois une caisse de résonance des fantasmes et des terreurs et une conscience critique, que ces contributions veulent rendre compte de ce rapport avec l’espace, dont l’humain a lui-même organisé la planétarisation et – paradoxalement – la déshumanisation.

Une comparaison des deux grandes villes luxembourgeoises, à travers les données du dernier recensement de 2001, apporte un nouvel éclairage des structures économiques et géographiques de leur population urbaine. En effet, nous remarquons que les villes de Luxembourg et d’Esch-sur-Alzette connaissent un vieillissement démographique atténué par une concentration d’un grand nombre d’étrangers, ces der-niers étant notamment surreprésentés dans les tranches d’âge actif. Cependant, les étrangers ne présentent pas les mêmes caractéristiques, tant par rapport au niveau d’éducation que de l’emploi qu’ils occupent. Ainsi, près de la moitié des Eschois ayant terminé leurs études ont uniquement suivi l’enseignement primaire ; un quart des habitants de la capitale sont dans ce cas. Cet écart se reporte notamment sur la proportion d’ouvriers, bien plus importante à Esch-sur-Alzette (60% des hommes par exemple) qu’à Luxembourg-Ville (32%). Par contre, la ségrégation socio-spatiale paraît plus accentuée au sein de la capitale du Grand-Duché, cette différence étant notamment liée à l’hétérogénéité de l’activité professionnelle (secteur international et place financière entre autres).

Due to different natural, political and economic conditions, there are clear differences in the territorial distribution and temporal development of late medieval towns in the Greater Region. The map 'Cities of the Late Middle Ages' shows the cities which could be designated as cities in the Late Middle Ages, i.e. between the beginning of the 13th century and the year 1500. It is important that the definition of a late medieval town meets several criteria. [less ▲]

Villin is an actin-binding protein of the intestinal brush border that bundles, nucleates, caps, and severs actin in a Ca(2+)-dependent manner in vitro. Villin induces the growth of microvilli in transfected cells, an activity that requires a carboxyl-terminally located KKEK motif. By combining cell transfection and biochemical assays, we show that the capacity of villin to induce growth of microvilli in cells correlates with its ability to bundle F-actin in vitro but not with its nucleating activity. In agreement with its importance for microfilament bundling in cells, the KKEK motif of the carboxyl-terminal F-actin-binding site is crucial for bundling in vitro. In addition, substitutions of basic residues in a second site, located in the amino-terminal portion of villin, impaired its activity in cells and reduced its binding to F-actin in the absence of Ca(2+) as well as its bundling and severing activities in vitro. Altogether, these findings suggest that villin participates in the organization and stabilization of the brush border core bundle but does not initiate its assembly by nucleation of actin filaments.

The function of villin, an actin-binding protein, has been investigated by transfecting fibroblasts with cloned human cDNAs encoding wild-type villin or functional villin domains. Synthesis of large amounts of villin induced the growth of numerous long microvilli on cell surfaces together with the redistribution of F-actin. These microvilli contained a cytoskeleton of F-actin, and their appearance was frequently accompanied by the disappearance of stress fibers. The complete villin gene sequence was required to exert its morphogenic effect. Villin lacking one actin-binding domain (113 amino acids), located at its carboxyterminal end, did not induce growth if microvilli or stress fiber disruption. Our results indicate that villin plays a key role in vivo in the morphogenesis of microvilli. [less ▲]

Villin is an actin-binding protein that is associated with the cytoskeleton of brush border microvilli. In vitro, villin nucleates, caps or severs actin filaments in a Ca(2+)-dependent manner. In the absence of Ca2+, villin organizes microfilaments into bundles. Transfection of a villin-specific cDNA into cultured cells that do not produce this protein results in the growth of long surface microvilli and the reorganization of the underlying actin cytoskeleton. Here we studied the effects of low concentrations of cytochalasin D on the induction of these plasma membrane-actin cytoskeleton specializations. Transfected cells were treated with concentrations of cytochalasin D that prevent the association of actin monomers with the fast-growing end of microfilaments in vitro. In villin-positive cells, cytochalasin D inhibited the growth of microvilli and promoted the formation of rodlet-like actin structures, which were randomly distributed throughout the cytoplasm. The formation of these structures was dependent on large amounts of villin and on the integrity of an actin-binding site located at the carboxy terminus of villin, which is required for microfilament bundling in vitro and for the growth of microvilli in vivo. The effect of cytochalasin D was reversible. The observation of living cells by video-imaging revealed that when cytochalasin D was removed, rapid disassembly of actin rodlets occurred after a lag phase. The present data stress the important role of the plasma membrane in the organization of the actin cytoskeleton and suggest that the extension of the microvillar plasma membrane is dependent on the elongation of microfilaments at their fast-growing end. Inhibition of microfilament elongation near the plasma membrane by cytochalasin D may result in the 'random' nucleation of actin filaments throughout the cytoplasm. On the basis of the present data, we propose that villin is involved in the assembly of the microvillar actin bundle by a mechanism that does not prevent monomer association with the preferred end of microfilaments. For instance, villin may stabilize actin filaments by lateral interactions. The functional importance of the carboxy-terminal F-actin binding site in such a mechanism is stressed by the fact that it is required for the formation of F-actin rodlets in cytochalasin D-treated cells. Finally, our data further emphasize the observations that the effects of cytochalasin D in living cells can be modulated by actin-binding proteins. [less ▲]
