Wählen per Internet verändert die Schweiz

Der Autor befasst sich mit dem Thema e-Voting am Beispiel der Schweiz. Umwählen zu gehen, begibt sich der Bürger auf Wählerseiten im Internet. Dort beantwortet er zuerst 10 Fragen zu bedeutsamen politischen Themen. Je nach seinen Antworten werden die dafür politisch eintretenden Kandidaten vorgestellt. Der Wähler kann sich nun detailliert über sie und ihre politischen Positionen informieren und dann entscheiden, welchem Politiker er seine Stimme gibt. Voraussetzung hierfür ist, dass die Kandidaten präzise Angaben über ihre Person und die von ihnen vertretene Politik im Internet zugänglich machen, da sie ansonsten auf den Wahlseiten nicht zugelassen würden und somit ihre Chancen, gewählt zu werden, minimieren würden. Hat der Bürger sich festgelegt, schickt er das Dokument zur Auswertung an einen Server des Staates, der dann innerhalb von Stunden das neue Wahlergebnis präsentieren könnte. Die Wahlseiten selbst werden wahrscheinlich nicht vom Staat kontrolliert, da die Regierung diese manipulieren könnte. Wenn aber die Gestaltung der Seiten in private Hand gelegt wird, besteht die Gefahr, dass die Listen nicht als offizielle Wahllisten anerkannt werden. Hier besteht also noch Klärungsbedarf. Ein klarer Vorteil solcher Wahlseiten ist, dass die Ziele und Interessen der Politiker noch transparenter werden. Das Internet bietet dem Bürger die Möglichkeit, seine persönlichen Interessen mit denen der Politiker zu vergleichen und sich dann nach einem Abwägunsprozess zu entscheiden. ,,In einigen Jahren werden hier zu Lande Wahlurnen ganz verschwinden", prophezeit der Autor und verweist auf die Arbeit einer Projektgruppe, die die noch offenen Fragen des E-Votings klären will.

Exposure to stallion accelerates the onset of mares' cyclicity.

Horses (Equus caballus) belong to the group of seasonally polyestrous mammals. Estrous cycles typically start with increasing daylight length after winter, but mares can differ greatly in the timing of onset of regular estrus cycles. Here, we test whether spatial proximity to a stallion also plays a role. Twenty-two anestrous mares were either exposed to one of two stallions (without direct physical contact) or not exposed (controls) under experimental conditions during two consecutive springs (February to April). Ovarian activity was monitored via transrectal ultrasound and stallion's direct contact time with each mare was determined three times per week for one hour each. We found that mares exposed to a stallion ovulated earlier and more often during the observational period than mares that were not exposed to stallions. Neither stallion identity nor direct contact time, mare age, body condition, size of her largest follicle at the onset of the experiment, or parasite burden significantly affected the onset of cyclicity. In conclusion, the timing of estrous cycles and cycle frequency, i.e., crucial aspects of female reproductive strategy, strongly depend on how the mares perceive their social environment. Exposing mares to the proximity of a stallion can therefore be an alternative to, for example, light programs or elaborated hormonal therapies to start the breeding season earlier and increase the number of estrous cycles in horses.

Radiochemotherapy in locally advanced squamous cell carcinomas of the head and neck.

Squamous cell carcinoma of the head and neck (SCCHN) is a common disease that develops in the upper aerodigestive epithelium. The most important risk factors are tobacco and alcohol consumption. There is also increasing evidence that human papillomavirus plays an important role in the cause of SCCHN. The complex anatomy, the vital functions of the upper aerodigestive tract and the close proximity to vital structures, explain that the goal of treatment is not only to improve survival outcomes, but also to preserve organ function. Radiotherapy and surgery are the standard modalities of treatment, reflecting the locoregional predominance of SCCHN. Chemotherapy plays an important role in the treatment of patients with locoregionally advanced disease, in conjunction with radiotherapy and surgery. Indeed, standard therapy for resectable locoregionally advanced (stage III or IV) SCCHN cancers consists either of surgery and adjuvant chemoradiotherapy or definitive concomitant chemoradiotherapy, depending upon disease site, stage and resectability of the tumour, or institutional experience. Concomitant chemoradiotherapy has been shown in several randomised trials to improve disease-free and overall survival in the postoperative setting for resected disease with poor prognostic factors. Furthermore, multiple randomised studies and meta-analyses have shown that definitive chemoradiotherapy, as well anti-epidermal growth factor receptor treatment in one randomised study, improved disease-free and overall survival when compared with radiotherapy alone. This overview reviews the most relevant published studies on the multidisciplinary management of SCCHN and discusses future strategies to reduce locoregional failures.

Airway epithelial IL-15 transforms monocytes into dendritic cells.

IL-15 has recently been shown to induce the differentiation of functional dendritic cells (DCs) from human peripheral blood monocytes. Since DCs lay in close proximity to epithelial cells in the airway mucosa, we investigated whether airway epithelial cells release IL-15 in response to inflammatory stimuli and thereby induce differentiation and maturation of DCs. Alveolar (A549) and bronchial (BEAS-2B) epithelial cells produced IL-15 spontaneously and in a time- and dose-dependent manner after stimulation with IL-1beta, IFN-gamma, or TNF-alpha. Airway epithelial cell supernatants induced an increase of IL-15Ralpha gene expression in ex vivo monocytes, and stimulated DCs enhanced their IL-15Ralpha gene expression up to 300-fold. Airway epithelial cell-conditioned media induced the differentiation of ex vivo monocytes into partially mature DCs (HLA-DR+, DC-SIGN+, CD14+, CD80-, CD83+, CD86+, CCR3+, CCR6(+), CCR7-). Based on their phenotypic (CD123+, BDCA2+, BDCA4+, BDCA1(-), CD1a-) and functional properties (limited maturation upon stimulation with LPS and limited capacity to induce T cell proliferation), these DCs resembled plasmacytoid DCs. The effects of airway epithelial cell supernatants were largely blocked by a neutralizing monoclonal antibody to IL-15. Thus, our results demonstrate that airway epithelial cell-conditioned media have the capacity to differentiate monocytes into functional DCs, a process substantially mediated by epithelial-derived IL-15.

O-chromosome lethal frequencies in Serbian and Montenegrin Drosophila subobscura populations

Lethal chromosomal frequencies were obtained from three Drosophila subobscura samples from the Mt. Avala (Serbia) population in September 2003 (0.218), June 2004 (0.204) and September 2004 (0.250). These values and those from other Balkan populations studied previously (Petnica, Kamariste, Zanjic and Djerdap) were used to analyze the possible effect of population, year, month and altitude above sea level on lethal chromosomal frequencies. According to ANOVAS no effect were observed. Furthermore, the lethal frequencies of the Balkan populations did not vary according to latitude. This is probably due to the relative proximity and high gene flow between these populations. From a joint study of all the Palearctic D. subobscura populations so far analyzed, it can be deduced that the Balkan populations are located in the central area of the species distribution. Finally, it seems that lethal chromosomal frequencies are a consequence of the genetic structure of the populations.

Integración económica y localización industrial. Cataluña, la fábrica de España: ¿cuándo y por qué?

En este artículo se analizan los determinantes de la localización de la actividad industrial en España durante la segunda mitad del siglo XIX. El objetivo es estudiar la existencia de cambios en los factores explicativos de la localización, con el fin de identificar los efectos de la integración económica sobre la geografía industrial española. Para hacerlo, en primer lugar se analiza la literatura histórica existente. En segundo lugar, se describen las teorías que explican la localización de l'actividad. En tercer lugar, se realiza un análisis empírico de la localización y la concentración de la industria española al siglo XIX. A continuación, se propone un estudio econométrico de los determinantes de la localización industrial en dos cortes temporales, 1856 y 1893. Los resultados son consistentes con las teorías del comercio. Durante el decurso de la segunda mitad del siglo XIX, España paso a ser una economía integrada, la movilidad del trabajo y del capital se vio favorecida y como resultado, las diferencias relativas en las dotaciones de factores perdieron importancia en la explicación de las pautas de especialización industrial. Por el contrario, la integración económica favoreció la significación relativa de las economías de escala o de la proximidad a los mercados como elementos explicativos de la localización de la industria, favoreciendo, de esta manera, la aglomeración de la actividad industrial

Iowa Voters Judicial Directory, August 2012

Voter Information: • Answers to Questions about Judicial Retention Elections • Biographies of Judges on the 2012 Iowa Ballot

What you need to know about Judicial Retention Elections, August 2012

Retention elections are intended to focus on the professional competency of Iowa’s judges rather than the popularity of individual rulings. In a retention election, voters decide whether a judge should be retained or removed from office. If a judge receives a majority of “yes” votes, the judge serves another full term. If a judge receives a majority of “no” votes, the judge is removed from office at the end of the year.

A mechanism for localized lignin deposition in the endodermis.

The precise localization of extracellular matrix and cell wall components is of critical importance for multicellular organisms. Lignin is a major cell wall modification that often forms intricate subcellular patterns that are central to cellular function. Yet the mechanisms of lignin polymerization and the subcellular precision of its formation remain enigmatic. Here, we show that the Casparian strip, a lignin-based, paracellular diffusion barrier in plants, forms as a precise, median ring by the concerted action of a specific, localized NADPH oxidase, brought into proximity of localized peroxidases through the action of Casparian strip domain proteins (CASPs). Our findings in Arabidopsis provide a simple mechanistic model of how plant cells regulate lignin formation with subcellular precision. We speculate that scaffolding of NADPH oxidases to the downstream targets of the reactive oxygen species (ROS) that they produce might be a widespread mechanism to ensure specificity and subcellular precision of ROS action within the extracellular matrix.

A two-level analysis of the determinants of direct democratic choices in European, immigration and foreign policy in Switzerland

This article employs a unique data set - covering 25 popular votes on foreign, European and immigration/asylum policy held between 1992 and 2006 in Switzerland - in order to examine the conditional impact of context upon utilitarian, cultural, political and cognitive determinants of individual attitudes toward international openness. Our results reveal clear patterns of cross-level interactions between individual determinants and the project-related context of the vote. Thus, although party cues and political competence have a strong impact on individuals' support for international openness, this impact is substantially mediated by the type of coalition that is operating within the party elite. Similarly, subjective utilitarian and cultural considerations influence the voters' decision in interaction with the content of the proposal submitted to the voters as well as with the framing of the voting campaign.

Leadership at the upper echelons : three essays

"IT'S THE ECONOMY STUPID", BUT CHARISMA MATTERS TOO: A DUAL PROCESS MODEL OF PRESIDENTIAL ELECTION OUTCOMES. ABSTRACT Because charisma is assumed to be an important determinant of effective leadership, the extent to which a presidential nominee is more charismatic than his opponent should be an important determinant of voter choices. We computed a composite measure of the rhetorical richness of acceptances speeches given by U.S. presidential candidates at their national party convention. We added this marker of charisma to Ray C. Fair's presidential vote-share equation (1978; 2009). We theorized that voters decide using psychological attribution (i.e., due to macroeconomics and incumbency) as well as inferential processes (i.e., due to leader charismatic behavior) when voting. Controlling for the macro-level variables and incumbency in the Fair model, our results indicated that difference between nominees' charisma is a significant determinant of electoral success, particularly in close elections. This extended model significantly improves the precision of the Fair model and correctly predicts 23 out of the last 24 U.S. presidential elections. Paper 2: IT CEO LEADERSHIP, CORPORATE SOCIAL AND FINANCIAL PERFORMANCE. ABSTRACT We investigated whether CEO leadership predicted corporate financial performance (CFP) and corporate social performance (CSP). Using longitudinal data on 258 CEOs from 117 firms across 19 countries and 10 industry sectors, we found that determinants of CEO leadership (i.e., implicit motives) significantly predicted both CFP and CSP. As expected, the most consistent positive predictor was Responsibility Disposition when interacting with n (need for) Power. n Achievement and n Affiliation were generally negatively related or unrelated to outcomes. CSP was positively related to accounting measures of CFP. Our findings suggest that executive leader characteristics have important consequences for corporate level outcomes. Paper 3. PUNISHING THE POWERFUL: ATTRIBUTIONS OF BLAME AND LEADERSHIP ABSTRACT We propose that individuals are more lenient in attributing blame to leaders than to nonleaders. We advance a motivational explanation building on the perspective of punishment and on system justification theory. We conducted two scenario experiments which supported our proposition. In study 1, wrongdoer leader status was negatively related to blame and the perceived seriousness of the wrongdoing. In study 2, controlling for the Big-Five personality factor and individual differences in moral evaluation (i.e., moral foundations), wrongdoer leader status was negatively related with desired severity of punishment, and fair punishments were perceived as more just for non-leaders than for leaders.

Étude du mécanisme de transport des cations par la Na, K-ATPase et de son implication dans la migraine familiale hémiplégique de type 2

Résumé La Na,K-ATPase est une protéine transmembranaire, présente dans toutes les cellules de mammifères et indispensable à la viabilité cellulaire. Elle permet le maintien des gradients sodiques et potassiques à l'origine du potentiel membranaire en transportant 3 Na+ en dehors de la cellule contre 2 K+, grâce à l'énergie fournie par l'hydrolyse d'une molécule d'ATP. Le potentiel membranaire est indispensable au maintien de l'excitabilité cellulaire et à la transmission de l'influx nerveux. Il semblerait que la Na,K-ATPase soit liée à l'hypertension et à certains troubles neurologiques comme la Migraine Familiale Hémiplégique (1VIFH). La MFH est une forme de migraine avec aura, qui se caractérise par une hémiparésie. Cette forme de migraine est très rare. Elle se transmet génétiquement sur un mode autosomique dominant. Plusieurs mutations localisées dans le gène de la Na,K-ATPase ont été identifiées durant ces 3 dernières années. C'est la première fois qu'une maladie génétique est associée au gène de la Na,K-ATPase. La compréhension du fonctionnement de cette protéine peut donner des informations sur les mécanismes conduisant à ces pathologies. On sait que la fonction d'une protéine est liée à sa structure. L'étude de sa fonction nécessite donc l'étude de sa structure. Alors que la structure de la SERCA a été déterminée à haute résolution, par cristallographie, celle de la Na,K-ATPase ne l'est toujours pas. Mais ces 2 ATPases présentent une telle homologie qu'un modèle de la Na,K-ATPase a pu être élaboré à partir de la structure de la SERCA. Les objectifs de cette étude sont d'une part, de comprendre le contrôle de l'accessibilité du K+ extracellulaire àses sites de liaison. Pour cela, nous avons ciblé cette étude sur la 2ìème et la 31eme boucle extracellulaire, qui relient respectivement les segments transmembranaires (STM) 3-4 et 5-6. Le choix s'est porté sur ces 2 boucles car elles bordent le canal des cations formés des 4ième' Sième et 6'ème hélices. D'autre part, nous avons également essayer de comprendre les effets des mutations, liées à la Migraine Familiale Hémiplégique de type 2 (MFH2), sur la fonctionnalité de la Na,K-ATPase. Alors que les STM et les domaines cytoplasmiques sont relativement proches entre la Na,KATPase et la SERCA, les boucles extracellulaires présentent des différences. Le modèle n'est donc pas une approche fiable pour déterminer la structure et la fonction des régions extracellulaires. Nous avons alors utilisé une approche fonctionnelle faisant appel à la mutation dirigée puis à l'étude de l'activité fonctionnelle de la Na,K ATPase par électrophysiologie sur des ovocytes de Xenopus. En conclusion, nous pouvons dire que la troisième boucle extracellulaire participerait à la structure de la voie d'entrée des cations et que la deuxième boucle extracellulaire semble impliquée dans le contrôle de l'accessibilité des ions K+àses sites de liaison. Concernant les mutations associées à la MFH2, nos résultats ont montré une forte diminution de l'activité fonctionnelle de la pompe Na,K, inférieure aux conditions physiologiques de fonctionnement, et pour une des mutations nous avons observés une diminution de l'affmité apparente au K+ externe. Nous poumons faire l'hypothèse que l'origine pathologique de la migraine est liée à une diminution de l'activité de la pompe à Na+. Summary The Na,K-ATPase is a transmembrane protein, present in all mammalian cells and is necessary for the viability of the cells. It maintains the gradients of Na+ and K+ involved in the membrane potential, by transporting 3Na+ out the cell, and 2K+ into the cell, using the energy providing from one ATP molecule hydrolysis. The membrane potential is necessary for the cell excitability and for the transmission of the nervous signal. Some evidence show that Na,K-ATPase is involved in hypertension and neurological disorders like the Familial Hemiplegic Migraine (FHM). La FHM is a rare form of migraine characterised by aura and hemiparesis and an autosomal dominant transmission. Several mutations linked to the Na,KATPase gene have been identified during these 3 last years. It's the first genetic disorder associated with the Na,K-ATPase gene. Understand the function of this protein is important to elucidate the mechanisms implicated in these pathologies. The function of a protein is linked with its structure. Thus, to know the function of a protein, we need to know its structure. While the Ca-ATPase (SERCA) has been crystallised with a high resolution, the structure of the Na,K-ATPase is not known. Because of the great homology between these 2 ATPases, a model of the Na,K-ATPase was realised by comparing with the structure of the SERCA. The aim of this study is on one side, understand the control of the extracellular K+ accessibility to their binding sites. Because of theirs closed proximity with the cation pathway, located between the 4th, 5th and 6th helices, we have targeted this study on the 2nd and the 3rd extracellular loops linking respectively the transmembrane segment (TMS) 3 and 4, and the TMS 5 and 6. And on the other side, we have tried to understand the functional effects of mutations linked with the Familial Hemiplegic Migraine Type 2 (FHM2). In contrast with the transmembrane segments and the cytoplasmic domains, the extracellular loops show lots of difference between Na,K-ATPase and SERCA, the model is not a good approach to know the structure and the function of the extracellular loops. Thus, we have used a functional approach consisting in directed mutagenesis and the study of the functional activity of the Na,K-ATPase by electrophysiological techniques with Xenopus oocytes. In conclusion, we have demonstrated that the third extracellular loop could participate in the structure of the entry of the cations pathway and that the second extracellular loop could control the K+ accessibility to their binding sites. Concerning the mutations associated with the FHM2, our results showed a strong decrease in the functional activity of the Na,K-pump under physiological conditions and for one of mutations, induce a decrease in the apparent external K+ affinity. We could make the hypothesis that the pathogenesis of migraine is related to the decrease in Na,K-pump activity. Résumé au large publique De la même manière que l'assemblage des mots forme des phrases et que l'assemblage des phrases forme des histoires, l'assemblage des cellules forme des organes et l'ensemble des organes constitue les êtres vivants. La fonction d'une cellule dans le corps humain peut se rapprocher de celle d'une usine hydroélectrique. La matière première apportée est l'eau, l'usine électrique va ensuite convertir l'eau en énergie hydraulique pour fournir de l'électricité. Le fonctionnement de base d'une cellule suit le même processus. La cellule a besoin de matières premières (oxygène, nutriments, eau...) pour produire une énergie sous forme chimique, l'ATP. Cette énergie est utilisée par exemple pour contracter les muscles et permet donc à l'individu de se déplacer. Morphologiquement la cellule est une sorte de petit sac rempli de liquide (milieu intracellulaire) baignant elle-même dans le liquide (milieu extracellulaire) composant le corps humain (un adulte est constitué environ de 65 % d'eau). La composition du milieu intracellulaire est différente de celle du milieu extracellulaire. Cette différence doit être maintenue pour que l'organisme fonctionne correctement. Une des différences majeures est la quantité de sodium. En effet il y a beaucoup plus de sodium à l'extérieur qu'à l'intérieur de la cellule. Bien que l'intérieur de la cellule soit isolé de l'extérieur par une membrane, le sodium arrive à passer à travers cette membrane, ce qui a tendance à augmenter la quantité de sodium dans la cellule et donc à diminuer sa différence de concentration entre le milieu extracellulaire et le milieu intracellulaire. Mais dans les membranes, il existe des pompes qui tournent et dont le rôle est de rejeter le sodium de la cellule. Ces pompes sont des protéines connues sous le nom de pompe à sodium ou Na,K-ATPase. On lui attribue le nom de Na,K-ATPase car en réalité elle rejette du sodium (Na) et en échange elle fait entrer dans la cellule du potassium (K), et pour fonctionner elle a besoin d'énergie (ATP). Lorsque les pompes à sodium ne fonctionnent pas bien, cela peut conduire à des maladies. En effet la Migraine Familiale Hémiplégique de type 2, est une migraine très rare qui se caractérise par l'apparition de la paralysie de la moitié d'un corps avant l'apparition du mal de tête. C'est une maladie génétique (altération qui modifie la fonction d'une protéine) qui touche la pompe à sodium située dans le cerveau. On a découvert que certaines altérations (mutations) empêchent les pompes à sodium de fonctionner correctement. On pense alors que le développement des migraines est en partie dû au fait que ces pompes fonctionnent moins bien. Il est important de bien connaître la fonction de ces pompes car cela permet de comprendre des mécanismes pouvant conduire à certaines maladies, comme les migraines. En biologie, la fonction d'une protéine est étudiée à travers sa structure. C'est pourquoi l'objectif de cette thèse a été d'étudier la structure de la Na,K-ATPase afin de mieux comprendre son mécanisme d'action.

E-tools for civic education : experiences from the election campaign in Switzerland 2007

Political participation is often very low in Switzerland especially among students and young citizens. In the run-up to the Swiss parliamentary election in October 2007 several online tools and campaigns were developed with the aim to increase not only the level of information about the political programs of parties and candidates, but also the electoral participation of younger citizens. From a practical point of view this paper will describe the development, marketing efforts and the distribution as well as the use of two of these tools : the so-called "Parteienkompass" (party compass) and the "myVote"-tool - an online voting assistance tool based on an issue-matching system comparing policy preferences between voters and candidates on an individual level. We also havea look at similar tools stemming from Voting Advice Applications (VAA) in other countries in Western Europe. The paper closes with the results of an evaluation and an outlook to further developments and on-going projects in the near future in Switzerland.

European integration, FDI and the internal geography of trade : evidence from Western European border regions

In this paper we use a gravity model to study the trade performance of French and Spanishborder regions relatively to non-border regions, over the past two decades. We find that,controlling for their size, proximity and location characteristics, border regions trade onaverage between 62% and 193% more with their neighbouring country than other regions,and twice as much if they are endowed with good cross border transport infrastructures.Despite European integration, however, this trade outperformance has fallen for the mostperipheral regions within the EU. We show that this trend was linked in part to a shift in the propensity of foreign investors to move their affiliates from the regions near their home market to the regions bordering the EU core.
