Changing Religiosity, Changing Politics? The Influence of 'Belonging' and 'Believing' on Political Attitudes in Switzerland

Starting from theories of secularization and of religious individualization, we propose a two-dimensional typology of religiosity and test its impact on political attitudes. Unlike classic conceptions of religiosity used in political studies, our typology simultaneously accounts for an individual's sense of belonging to the church (institutional dimension) and his/her personal religious beliefs (spiritual dimension). Our analysis, based on data from the World Values Survey in Switzerland (1989-2007), shows two main results. First, next to evidence of religious decline, we also find evidence of religious change with an increase in the number of people who "believe without belonging." Second, non-religious individuals and individuals who believe without belonging are significantly more permissive on issues of cultural liberalism than followers of institutionalized forms of religiosity.

Gamma Knife, CyberKnife, TomoTherapy: gadgets or useful tools?

Purpose of reviewThis review provides information and an update on stereotactic radiosurgery (SRS) equipment, with a focus on intracranial lesions and brain neoplasms.Recent findingsGamma Knife radiosurgery represents the gold standard for intracranial radiosurgery, using a dedicated equipment, and has recently evolved with a newly designed technology, Leksell Gamma Knife Perfexion. Linear accelerator-based radiosurgery is more recent, and originally based on existing systems, either adapted or dedicated to radiosurgery. Equipment incorporating specific technologies, such as the robotic CyberKnife system, has been developed. Novel concepts in radiation therapy delivery techniques, such as intensity-modulated radiotherapy, were also developed; their integration with computed tomography imaging and helical delivery has led to the TomoTherapy system. Recent data on the management of intracranial tumors with radiosurgery illustrate the trend toward a larger use and acceptance of this therapeutic modality.SummarySRS has become an important alternative treatment for a variety of lesions. Each radiosurgery system has its advantages and limitations. The 'perfect' and ubiquitous system does not exist. The choice of a radiosurgery system may vary with the strategy and needs of specific radiosurgery programs. No center can afford to acquire every technology, and strategic choices have to be made. Institutions with large neurosurgery and radiation oncology programs usually have more than one system, allowing optimization of the management of patients with a choice of open neurosurgery, radiosurgery, and radiotherapy. Given its minimally invasive nature and increasing clinical acceptance, SRS will continue to progress and offer new advances as a therapeutic tool in neurosurgery and radiotherapy.
