Tels parents, tels enfants? L'utilisation de données de seconde main dans l'étude des influences politiques parentales en Suisse

''Like Parents, Like Children?'' Using Secondary Data in the Study of Parental Political Influence in Switzerland: This text is devoted to the intergenerational transmission of left-right ideological orientation. Using data from the Swiss Household Panel (www.swisspanel.ch), collected both directly and through intermediaries, it raises the question of the validity of second-hand information, which is discussed on several points. The article also shows that there is a strong long-term coherence between the ideological orientation of parents and their children. It also highlights the fact that the link is not the same for boys as for girls, and it varies between generations. Finally, it shows that strong upward social mobility, compared to the original environment, facilitates emancipation from parental ideology, social inertia being greater for downward and horizontal mobility. Ce texte est consacré à la transmission intergénérationnelle de l'orientation idéologique gauche-droite. Utilisant des données du Panel Suisse de Ménages (www.swisspanel.ch), collectées tant directement que par personnes interposées, il pose la question de la validité des informations de seconde main, qui est étudiée sur plusieurs points. L'article montre en outre qu'il existe à long terme une forte cohérence entre l'orientation idéologique des parents et de leurs enfants. Il met aussi en évidence que ce lien n'est pas la même auprès des garçons qu'auprès des filles, et qu'il varie entre les générations. Finalement, il montre qu'une forte ascension sociale par rapport au milieu d'origine facilite l'émancipation des orientations idéologiques parentales, l'inertie étant plus forte pour les trajectoires descendantes et horizontales.

Beyond Conditionality versus Cooperation: Power and Resistance in the Case of EU Mobility Partnerships and Swiss Migration Partnerships

Migration partnerships (MPs) have become a key instrument in global migration governance. In contrast to traditional unilateral approaches, MPs emphasize a more comprehensive and inclusive tackling of migration issues between countries of origin, transit, and destination. Due to this cooperation-oriented concept, most of the existing studies on MPs neglect power questions within partnerships in line with the official discourse, reflecting a broader trend in the international migration governance literature. Others take an instrumentalist view in analysing the power of partnerships or focus on soft power. Illustrated with the examples of the European Mobility Partnerships (EU MPs) and the Swiss Migration Partnerships (CH MPs), we conduct an analysis based on a concept of productive power drawing on post-structural and post-colonial insights. Our main argument is that in contrast to their seemingly consent-oriented and technical character, MPs are sites of intense (discursive) struggles, and (re-)produce meanings, subjects, and resistances. A productive power analysis allows us to move beyond the dichotomy in the literature between coercion and cooperation, as well as between power and resistance more broadly.

Intergenerational differences in cardiovascular risk factor levels in Switzerland

Background: There is little information regarding cardiovascular risk factor (CV RF) trends in Switzerland. We aimed at assessing generation differences in CV RFs by comparing CV RFs levels within selected age groups separated by a 20 year time lag. Design: Two population-based surveys. Methods: Data from the Monica (1984-1986) and Colaus (2004-2006) surveys were used. Analyses were stratified by sex and age groups (35-44, 45-54, 55-64 and 65-75 years). Results: No changes were found for BMI levels and status between surveys: in men, 26}3, 26}3, 27}4 and 27}4 kg/m2 for age groups 35-44, 45-54, 55-64 and 65-74, respectively, in MONICA, vs. 26}4, 26}4, 27}4 and 28}4 kg/m2 in COLAUS, p=NS, in women: 24}4, 26}4, 26}4 and 26}5 kg/m2 in MONICA, vs. 24}5, 25}5, 26}5 and 26}5 kg/m2 in COLAUS, p=NS. Similar results were found after adjusting for education. Smoking prevalence increased in men: 28, 30, 22 and 15% for age groups 35-44, 45-54, 55-64 and 65-74, respectively, in MONICA, vs. 35, 29, 28 and 21% in COLAUS. In women, changes differed according to age: 39, 26, 16 and 18%, in MONICA vs. 28, 30, 22 and 15% in COLAUS. Blood pressure decreased in the younger age groups and remained constant in the older ones: in men, systolic blood pressure was 129}15, 133}16, 138}18 and 143}21 mm Hg in MONICA, vs. 125}12, 129}15, 137}16 and 144}19 mm Hg in COLAUS, p<0.01. Similar findings were obtained after adjusting for education. Prevalence of hypertension increased, due to an increase in the prevalence of treated subjects, in men : 4, 8, 16 and 19% for age groups 35-44, 45-54, 55-64 and 65-74, respectively, in MONICA, vs. 5, 14, 31 and 46% in COLAUS, p<0.05; in women: 2, 10, 16, and 24% in MONICA, vs. 4, 12, 24, and 34% in COLAUS, p<0.05. This increase was stronger in men: 14, 17, 23 and 31% for age groups 35-44, 45-54, 55-64 and 65-74, respectively, in MONICA vs. 10, 21, 41 and 55% in COLAUS, p<0.01 and smaller in women: 6, 15, 24 and 44% in MONICA vs. 6, 16, 30 and 42% in COLAUS, p=NS. Similar findings were obtained after adjusting for education. Conclusion: With the exception of BMI, the newer Swiss generations appear to have a worse CV profile than the older generations. This is especially true regarding smoking and hypertension.

Huella de carbono de vivienda y movilidad en Concepción, Chile. Uso del cálculo de huella de carbono para concretar y solucionar problemáticas sociales en barrios desfavorecidos. El caso de Pedro de Valdivia Bajo y Cerro Centinela

En este proyecto se ha calculado la huella de carbono parcial, es decir, únicamente se ha tenido en cuenta la movilidad y la energía usada en la vivienda. Se ha aplicado la metodología creada por Mathis Wackernagel y William Rees en 1997 para el cálculo de la huella ecológica. Diferentes barrios distribuidos a distintas distancias del CBD (Central Business District) de Concepción (Chile), han sido los objetos de estudio de la Huella de Carbono y en concreto se ha focalizado la atención en dos barrios de bajas rentas (Cerro Centinela y Pedro de Valdivia Bajo). En ellos se ha propuesto mejoras tanto ecológicas como sociales para aumentar la calidad de vida de los vecinos.

Implementation of the Federal Highway Administration Final Rule on Work Zone Safety and Mobility, 2007

The Federal Highway Administration published the final rule updating 23 CFR 630 Subpart J in September 2004. The revised rule requires agencies using federal funding to address both safety and mobility in planning and construction of roadway improvements. The Iowa Department of Transportation (Iowa DOT) requested the assistance of the Center for Transportation and Research in developing guidance for a policy and procedures to comply with the final rule. This report describes an in-depth examination of current Iowa DOT project development processes for all types of improvements, including maintenance, as well as a detailed characterization of work zone impact considerations throughout project completion. To comply with both the letter and perceived intent of the final rule on safety and mobility, the report features a suggested work zone policy statement and suggested revisions in the Iowa DOT project development processes, including a definition of the key element: significant projects.

Feasibility of Visualization and Simulation Applications to Improve Work Zone Safety and Mobility

Visualization is a relatively recent tool available to engineers for enhancing transportation project design through improved communication, decision making, and stakeholder feedback. Current visualization techniques include image composites, video composites, 2D drawings, drive-through or fly-through animations, 3D rendering models, virtual reality, and 4D CAD. These methods are used mainly to communicate within the design and construction team and between the team and external stakeholders. Use of visualization improves understanding of design intent and project concepts and facilitates effective decision making. However, visualization tools are typically used for presentation only in large-scale urban projects. Visualization is not widely accepted due to a lack of demonstrated engineering benefits for typical agency projects, such as small- and medium-sized projects, rural projects, and projects where external stakeholder communication is not a major issue. Furthermore, there is a perceived high cost of investment of both financial and human capital in adopting visualization tools. The most advanced visualization technique of virtual reality has only been used in academic research settings, and 4D CAD has been used on a very limited basis for highly complicated specialty projects. However, there are a number of less intensive visualization methods available which may provide some benefit to many agency projects. In this paper, we present the results of a feasibility study examining the use of visualization and simulation applications for improving highway planning, design, construction, and safety and mobility.

Sedimentation of macroscopic rigid knots and its relation to gel electrophoretic mobility of DNA knots.

We address the general question of the extent to which the hydrodynamic behaviour of microscopic freely fluctuating objects can be reproduced by macrosopic rigid objects. In particular, we compare the sedimentation speeds of knotted DNA molecules undergoing gel electrophoresis to the sedimentation speeds of rigid stereolithographic models of ideal knots in both water and silicon oil. We find that the sedimentation speeds grow roughly linearly with the average crossing number of the ideal knot configurations, and that the correlation is stronger within classes of knots. This is consistent with previous observations with DNA knots in gel electrophoresis.

Biomechanical concept and clinical outcome of dual mobility cups

La luxation d'une prothèse totale de la hanche est une complication majeure en termes de morbidité pour le patient et des coûts pour le système de santé. Cette complication est retrouvée entre 2 à 3% selon les séries (1-3) pour des prothèses primaires, et beaucoup plus élevée suite à des révisions. Pour remédier à ce problème, des systèmes de prothèses contraintes sont une option, cependant associés à des descellements fréquents entre 10 à 26 % selon les séries (4-6). Ces échecs étant en partie expliqués par une usure rapide des surfaces de frottements due aux fortes contraintes, mais également par les contraintes cupule-os occasionnant des descellements mécaniques (7). Par conséquent, pour augmenter la stabilité, tout en évitant les contraintes sur le couple de frottement, Bousquet développe, en 1976, une prothèse totale de hanche « à double mobilité ». Ce système consiste à combiner deux articulations apparentes, premièrement une tête métallique dans un insert de polyéthylène, articulé lui- même dans la concavité d'une cupule métallique fixée au bassin. En tant que tel, ce système biomécanique réduirait en théorie le risque de luxation. Dès lors, on aperçoit depuis environ 15 ans une augmentation progressive de l'utilisation de ce type d'implants que ce soit comme implant primaire ou secondaire, chez des patients jeunes ou âgés. Cependant, des études in vitro, ont montré que des grandes surfaces de friction sont associées à une augmentation de l'usure du polyéthylène (8). En revanche, les données sur la cinématique et l'usure, in vivo, de ce type d'implant étaient jusqu'alors limitées. Depuis quelques années, un certain nombre d'études cliniques avec un follow up significatif ont été publiées. CONCLUSIONS ET PERSPECTIVES FUTURES La prothèse totale de hanche à double mobilité, développée par Bousquet dans les années 1970, est un concept novateur dans l'arthroplastie totale de hanche. Depuis sa première conception, de nombreuses améliorations ont été adoptées. Cependant, ses effets à long terme sur la survie de l'implant doivent encore être effectué. Certes, des études ont montré un net effet sur la réduction du taux de luxation des prothèses primaires, lors de révision ou après résection tumorale. Toutefois, compte tenu des données limitées à long terme sur le taux d'usure et le descellement aseptique, il convient d'utiliser ce type d'implant avec prudence, en particulier lors d'arthroplastie primaire chez des patients jeunes.

Interrelation among Economic Growth, Income Inequality, and Fiscal Performance: Evidence from Anglo-Saxon Countries

The interrelation among economic growth, income inequality, and fiscal performance is very complex. The paper provides the analysis of the interrelations among these variables jointly by the structural VAR methodology, examining also transmission channels among them. This approach allows exploring dynamic interactions among them and feedback effects on each other. The empirical analysis is implemented for the Anglo-Saxon countries, the UK, the USA, and Canada. We find that income inequality has negative effect on economic growth in the case of the UK. The effect is positive in the cases of the USA and Canada. The increase in income inequality worsens fiscal performance for all the countries

A high-mobility, low-cost phenotype defines human effector-memory CD8+ T cells.

T cells move randomly ("random-walk"), a characteristic thought to be integral to their function. Using migration assays and time-lapse microscopy, we found that CD8+ T cells lacking the lymph node homing receptors CCR7 and CD62L migrate more efficiently in transwell assays, and that these same cells are characterized by a high frequency of cells exhibiting random crawling activity under culture conditions mimicking the interstitial/extravascular milieu, but not when examined on endothelial cells. To assess the energy efficiency of cells crawling at a high frequency, we measured mRNA expression of genes key to mitochondrial energy metabolism (peroxisome proliferator-activated receptor gamma coactivator 1beta [PGC-1beta], estrogen-related receptor alpha [ERRalpha], cytochrome C, ATP synthase, and the uncoupling proteins [UCPs] UCP-2 and -3), quantified ATP contents, and performed calorimetric analyses. Together these assays indicated a high energy efficiency of the high crawling frequency CD8+ T-cell population, and identified differentially regulated heat production among nonlymphoid versus lymphoid homing CD8+ T cells.
