Understanding Political Knowledge and Its Influence on Voting Preferences in the 2007 Federal Election

In this article we propose a model to explain how voters' perceptions of their ideological proximity to a party affect their propensity to vote for that party. We argue that political knowledge plays a crucial moderating role in the relationship between party proximity and voting propensity. It is necessary, however, to distinguish between institutional knowledge (information about the political system) and party knowledge (information about the parties' left-right positions). An analysis of survey data from the 2007 Swiss federal elections supports our main hypothesis that party knowledge enhances the link between party proximity and voting propensity. Institutional knowledge may have additional influence, but clear evidence for this effect was obtained only for propensities to vote for the Swiss People's Party (SVP). Overall, the impact of political knowledge was found to be substantial, even after controlling for the outstanding influence of party identification and other predictors of voting propensities

Riesenzellarteriitis : Ätiologische Erkenntnisse und diagnostische Herausforderung für den Pathologen [Giant cell arteritis : Etiological knowledge and diagnostic challenge for pathologists].

Giant cell arteritis is a potentially systemic disease of medium-sized and large caliber arteries, showing a preferential manifestation in the extracranial branches of the carotid artery. The diagnosis is oriented to clinical and histomorphological criteria which will be critically reviewed. Particular emphasis is placed on the differentiation from normal aging processes and from healing stages under steroid therapy. In addition, the advances in our understanding of the disease pathomechanism during the last 10 years will be briefly presented as the basis for the hitherto empiric steroid treatment.

Current state of knowledge on neuroendocrine small bowel tumours: non-systematic review of the literature based on one case.

More than 60% of neuroendocrine tumours, also called carcinoids, are localised within the gastrointestinal tract. Small bowel neuroendocrine tumours have been diagnosed with increasing frequency over the past 35 years, being the second most frequent tumours of the small intestine. Ileal neuroendocrine tumours diagnosis is late because patients have non-specific symptoms. We have proposed to illustrate as an example the case of a patient, and on its basis, to make a brief review of the literature on small bowel neuroendocrine tumours, resuming several recent changes in the field, concerning classification criteria of these tumours and new recommendations and current advances in diagnosis and treatment. This patient came to our emergency department with a complete bowel obstruction, along with a 2-year history of peristaltic abdominal pain, vomits and diarrhoea episodes. During emergency laparotomy, an ileal stricture was observed, that showed to be a neuroendocrine tumour of the small bowel.

Organismos filantrópicos y no gubernamentales en el desarrollo de nuevas ciencias y tecnologías: el caso de las micro y nanotecnologías en México

RESUMEN: La emergencia de nuevas ciencias y tecnologías vienen acompañadas de nuevas dinámicas en la producción, el uso y la diseminación de nuevos conocimientos científicos y tecnológicos. Estas nuevas dinámicas se reflejan en la reorganización de las actividades científicas, en la creación o la reorientación de nuevas temáticas en la investigación, en la emergencia de nuevas preocupaciones y debates sobre los riesgos e implicaciones sociales, y en la participación de nuevos actores en el desarrollo de la ciencia y la tecnología, entre otros factores. En este artículo se presentan los resultados del estudio sobre las funciones de un organismo con orígenes filantrópicos y no gubernamental que ha sido central en el desarrollo de los sistemas microelectromecánicos (MEMS) en México. Las funciones que se analizan han sido y son desarrolladas en las diferentes etapas del desarrollo de esta tecnología emergente en este país. Además de mostrar las funciones desempeñadas por este tipo de organismo, este texto se cuestiona sobre la modelización de las relaciones entre las diferentes entidades presentes en el desarrollo e instalación de nuevas tecnologías. En las conclusiones intentamos avanzar algunos elementos para tomar en cuenta estos organismos y enriquecer los estudios sociales sobre las nuevas ciencias y tecnologías. ABSTRACT: The emergence of new sciences and technologies come with new dynamics in the production, use and dissemination of new scientific and technological knowledge. These new dynamics are reflected in the reorganization of scientific activities, in creating or redirecting new topics in research, in the emergence of new concerns and debates about the risks and social implications, and the participation of new actors in the development of science and technology, among other factors. This article presents the results of the study on the functions of an organism with philanthropic and non-governmental sources that has been central to the development of microelectromechanical systems (MEMS) in Mexico. The functions have been discussed and are developed at different stages of development of this emerging technology in this country. In addition to showing the functions of such a body, this text is questioned on modeling the relationships between the various entities in the development and deployment of new technologies. In the conclusions we try moving some elements to take into account these organisms and enrich social studies on the new sciences and technologies.

Improvement of cardiovascular risk prediction: time to review current knowledge, debates, and fundamentals on how to assess test characteristics.

Cardiovascular risk assessment might be improved with the addition of emerging, new tests derived from atherosclerosis imaging, laboratory tests or functional tests. This article reviews relative risk, odds ratios, receiver-operating curves, posttest risk calculations based on likelihood ratios, the net reclassification improvement and integrated discrimination. This serves to determine whether a new test has an added clinical value on top of conventional risk testing and how this can be verified statistically. Two clinically meaningful examples serve to illustrate novel approaches. This work serves as a review and basic work for the development of new guidelines on cardiovascular risk prediction, taking into account emerging tests, to be proposed by members of the 'Taskforce on Vascular Risk Prediction' under the auspices of the Working Group 'Swiss Atherosclerosis' of the Swiss Society of Cardiology in the future.
