Swiss Political Science Review, EarlyView.Abstract Web‐based surveys have gained popularity due to their cost‐effectiveness and changing participation habits, a trend accelerated by the COVID‐19 pandemic. This raises questions about the continued value of paper‐based surveys in mixed‐mode studies like the Swiss Election Study (Selects), which uses a push‐to‐web design, offering a paper ...

A New Optimization Problem in FSO Communication System [PDF]
IEEE Communications Letters, 2018 According to the physical phenomena of atmospheric channels and wave propagation, performance of wireless communication systems can be optimized by simply adjusting its parameters. This way is more economically favorable than consuming power or using processing techniques.

Poverty Attributions and Voting Choices in the 2023 Swiss National Elections
Swiss Political Science Review, EarlyView.Abstract Is poverty a relevant issue for Swiss electoral politics and political behavior? In this paper we answer that question by showing that citizens’ agreement with different causal attributions of poverty matters for their voting decisions. Of highest relevance is the difference between an “individual blame” explanation (i.e., the poor are lazy ...

Tijdschrift voor Economische en Sociale Geografie, EarlyView.Abstract Several theories have been proposed to explain the family changes that have occurred in Europe since the mid‐1960s. It is often assumed that as these changes occurred simultaneously; they have a common origin and represent the same demographic shift.

RF/FSO and THz/FSO Relaying Systems
This chapter delves into the potential of relay-assisted transmission to alleviate fading in free-space optical (FSO) systems. We focus on evaluating the efficacy of a dual-hop relay system for RF (millimeter-wave and terahertz)/FSO (RF/FSO) communications in the presence of pointing errors.

Importance of noise models in FSO communications [PDF]
EURASIP Journal on Wireless Communications and Networking, 2014 يعد الاتصال البصري الفضائي الحر (FSO) تقنية ناشئة توفر نطاقًا تردديًا هائلاً وطيفًا بدون ترخيص ووصلة آمنة للغاية. تُستخدم الثنائيات الضوئية للانهيار الجليدي (APD) عادةً للكشف عن إشارات FSO عالية السرعة، حيث تُظهر الضوضاء توزيع الضوضاء الغاوسية المعتمدة على الإشارة (SDGN) بدلاً من توزيع الضوضاء الغاوسية المستقلة عن الإشارة (الإشارة).

Istical Characterization of Aerosols' Liquid Water Content and Visibility for Terrestrial FSO Links
, 2012 Liquid water content (LWC) is a microphysical parameter which is used to characterize fog/cloud and other particulates. In the absence of precipitation higher amount of LWC depicts dense fog, significantly reducing visibility and causing performance ...

The Mystery of Success: How Family Background Shapes Social Mobility
Review of Income and Wealth, Volume 72, Issue 3, August 2026.ABSTRACT This study examines social mobility and its underlying drivers in Switzerland. We use a rich administrative dataset covering nearly 700,000 individuals across 23 birth cohorts. Rather than relying on traditional parent–child associations, we quantify the overall influence of familial factors, providing a wide‐ranging indicator of social ...
