Le choix de vivre en ville-centre : interactions entre mobilité quotidienne et mobilité résidentielle

Cet article s'insère dans un double débat : celui de l'influence des formes urbaines sur les pratiques modales et celui relatif au regain d'attractivité des villes pour les classes moyennes supérieures. Il aborde les interactions entre mobilité quotidienne et mobilité résidentielle dans un nouveau quartier d'une ville de taille moyenne. Les choix résidentiels étudiés se basent en grande partie sur la valorisation de la proximité. Toutefois, plusieurs styles de mobilité coexistent au sein de ce même contexte territorial en fonction notamment des parts modales des transports publics et de l'automobile.

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Judge Reuben Noble Praises the Iowa State Building at the 1893 World’s Columbian Exposition BACKGROUND: REUBEN NOBLE REUBEN NOBLE was born on the 14th of April, 1821, in Ada County, Mississippi, where his father was a farmer. When he was eighteen years of age, Noble began to study law and was admitted to the bar at twenty-one. In 1843, he came to Iowa, making his home at Garnavillo, in Clayton County. In 1854, Noble was elected to the legislature as a free soil Whig and upon the organization of the House was chosen Speaker, serving in the regular session of 1854 and extraordinary session of 1855. At the first Republican State Convention of 1856, he was placed at the head of the ticket for presidential elector. Four years later, he was a delegate to the National Convention that nominated Abraham Lincoln for president. Up to the time of the attempt of the Republicans to remove President Johnson by impeachment, Noble had been a prominent leader of that party. But approving of the policies of the President, he left the Republicans and from that time became a Democrat. In 1866, Noble was nominated by the Democrats for Representative in Congress but was defeated by William B. Allison. In 1886, he was one of the organizers of the Pioneer Lawmakers’ Association and was its first president, never missing a session during the remainder of his life. Noble was the leader of the bar of northeastern Iowa beginning in 1850. As a compliment to his high standing and eminent qualifications as a jurist, the citizens of the Tenth Judicial District elected him to tthe office of district judge in the fall of 1874.

Typologien und Wandel : Die kantonalen Parteiensysteme im letzten Drittel des 20. Jahrhunderts

Die bisherigen Versuche die kantonalen Parteiensysteme zu typologisieren kommen zu ganz unterschiedlichen Ergebnissen. Der Grund dafür liegt darin, dass sie sich auf nur wenige und unterschiedliche Parteiensystemmerkmale abstützten. Vernachlässigt wird dabei zudem der Aspekt eines allfälligen Wandels der Parteiensysteme. Ziel dieses Artikels ist es, ausgehend von einer Typologisierung, welche möglichst alle wichtigen Eigenheiten der kantonalen Parteiensysteme berücksichtigt, den Wandel der Parteiensysteme zu analysieren und mögliche Entwicklungen aufzuzeigen. Die Ergebnisse weisen darauf hin, dass bei gewissen Systemmerkmalen trotz einer Annäherung in nächster Zeit nicht davon auszugehen ist, dass die kantonalen Parteiensysteme auf das nationale Parteiensystem hin konvergieren.

Telomere dynamics rather than age predict life expectancy in the wild.

Despite accumulating evidence from in vitro studies that cellular senescence is linked to telomere dynamics, how this relates to whole-organism senescence and longevity is poorly understood and controversial. Using data on telomere length in red blood cells and long-term survival from wild Alpine swifts of a range of ages, we report that the telomere length and the rate of telomere loss are predictive of life expectancy, and that slow erosion of relatively long telomeres is associated with the highest survival probabilities. Importantly, because telomere dynamics, rather than chronological age, predict life expectancy, our study provides good evidence for a mechanistic link between telomere erosion and reduced organism longevity under natural conditions, chronological age itself possibly not becoming a significant predictor until very old ages beyond those in our sample.

Association of T-zone reticular networks and conduits with ectopic lymphoid tissues in mice and humans.

Ectopic or tertiary lymphoid tissues (TLTs) are often induced at sites of chronic inflammation. They typically contain various hematopoietic cell types, high endothelial venules, and follicular dendritic cells; and are organized in lymph node-like structures. Although fibroblastic stromal cells may play a role in TLT induction and persistence, they have remained poorly defined. Herein, we report that TLTs arising during inflammation in mice and humans in a variety of tissues (eg, pancreas, kidney, liver, and salivary gland) contain stromal cell networks consisting of podoplanin(+) T-zone fibroblastic reticular cells (TRCs), distinct from follicular dendritic cells. Similar to lymph nodes, TRCs were present throughout T-cell-rich areas and had dendritic cells associated with them. They expressed lymphotoxin (LT) β receptor (LTβR), produced CCL21, and formed a functional conduit system. In rat insulin promoter-CXCL13-transgenic pancreas, the maintenance of TRC networks and conduits was partially dependent on LTβR and on lymphoid tissue inducer cells expressing LTβR ligands. In conclusion, TRCs and conduits are hallmarks of secondary lymphoid organs and of well-developed TLTs, in both mice and humans, and are likely to act as important scaffold and organizer cells of the T-cell-rich zone.

HIV testing in Switzerland.

OBJECTIVES: To obtain information about the prevalence of, reasons for, and adequacy of HIV testing in the general population in Switzerland in 1992. DESIGN: Telephone survey (n = 2800). RESULTS: Some 47% of the sample underwent one HIV test performed through blood donation (24%), voluntary testing (17%) or both (6%). Of the sample, 46% considered themselves well or very well informed about the HIV test. Patients reported unsystematic pre-test screening by doctors for the main HIV risks. People having been in situations of potential exposure to risk were more likely to have had the test than others. Overall, 85% of those HIV-tested had a relevant, generally risk-related reason for having it performed. CONCLUSIONS: HIV testing is widespread in Switzerland. Testing is mostly performed for relevant reasons. Pre-test counselling is poor and an opportunity for prevention is thus lost.

Estimating the apparent transverse relaxation time (R2(*)) from images with different contrasts (ESTATICS) reduces motion artifacts.

Relaxation rates provide important information about tissue microstructure. Multi-parameter mapping (MPM) estimates multiple relaxation parameters from multi-echo FLASH acquisitions with different basic contrasts, i.e., proton density (PD), T1 or magnetization transfer (MT) weighting. Motion can particularly affect maps of the apparent transverse relaxation rate R2(*), which are derived from the signal of PD-weighted images acquired at different echo times. To address the motion artifacts, we introduce ESTATICS, which robustly estimates R2(*) from images even when acquired with different basic contrasts. ESTATICS extends the fitted signal model to account for inherent contrast differences in the PDw, T1w and MTw images. The fit was implemented as a conventional ordinary least squares optimization and as a robust fit with a small or large confidence interval. These three different implementations of ESTATICS were tested on data affected by severe motion artifacts and data with no prominent motion artifacts as determined by visual assessment or fast optical motion tracking. ESTATICS improved the quality of the R2(*) maps and reduced the coefficient of variation for both types of data-with average reductions of 30% when severe motion artifacts were present. ESTATICS can be applied to any protocol comprised of multiple 2D/3D multi-echo FLASH acquisitions as used in the general research and clinical setting.
