Career Changers in Teaching Jobs: A Case Study Based on the Swiss Vocational Education System

This study investigates the determinants and motives of professionals who change career to vocational teaching. The framework for this study is the Swiss vocational education system, which requires that teachers of vocational subjects must have a prior career in that specific field. Thus, to work in teaching, every vocational teacher has to change his or her initial career. This paper focuses on the relevance of monetary motives for changing a career to teaching. Using a unique data set of trainee teachers, we show that professionals who change their careers to teaching earned on average more in their first career than comparable workers in the same occupation. Our findings additionally demonstrate that the average career changer still expects to earn significantly more as a teacher than in the former career. However, the study shows substantial heterogeneity and a zero wage elasticity of the teacher supply, suggesting that non-monetary motives are more relevant for career change than monetary factors.career change, occupational change, rate of return to education, wage differentials, teacher wages, vocational education and training

‘Vandalizing’ Father Hittite. Karabel, Orientalism and Historiographies

This paper provides a framework to highlight the entanglement of discovery and historiography based on the example of the rock-relief figure of Karabel (Turkey), a pivotal monument to recognize the Hittites and the biblical past. I lay out the common narrative of the re-discovery's story that resemble a hagiography, and I put it into perspective with critiques from post-colonial studies. Due to the ongoing damage at the figure of Karabel, I hypothesize that the one-sided role of the monument in the story of the re-discovery of the Hittites by western scholars is insufficient to avoid the radical rejection of the Karabel relief by some people. This article is theory-in-practice: it highlights some pitfalls and tells a story with more diversity, open thought, and considerations beyond traditional narratives of power in passéist oriental archaeology

Sacked and Cursed? New data on the transition from the city-state to the Hittite capital Hattuša

When: Karum Period: First centuries of the 2nd millennium B.C. when Assyrian and Anatolian merchants took part in large-scale commercial exchanges between Aššur and central Anatolia. Most of the epigraphic finds come  from the 19th century BC, and the 18th century is less known. We don’t know how the commercial exchanges came to an end. Until the establishment of the administration at the Hittite capital Hattuša/Boğazköy (1650), there is a hiatus in the epigraphical records for more than a century. Who: Anitta, son of Pithana, an ambitious ruler who created one of the first Kingdom in Central Anatolian (modern Turkey) in the mid 18th century.Where: Boğazköy (modern name, in Central Anatolia) was a city called Ḫattuš and was an exchange place in the Anatolian Network of the Karum period. The site was selected as the capital of the Hittites around 1650 by Ḫattušili I, the first well attested Hittite King

Unmanned Aerial Systems

Unmanned aerial platforms are a means to gather efficiently valuable aerial information to support the crisis manager for further tactical planning and deployment. They can provide continuous support to the coordinators and operators by scanning blocked sectors or establish an communication network. This chapter describes how aerial platforms were tailored to search and rescue (SAR) requirements, including the localisation and tracking of victims. In order to meet the end user demands, complementary platforms are proposed. A small long‐endurance solar aeroplane is used to provide the largest and fastest area coverage at the highest view, and therefore enabling the mapping functionality and potential detection of victims with operation times span up to a day. Complementary to the aeroplane, two rotary‐wing systems were deployed. A large coaxial‐quadrotor was used for outdoor delivery task and detailed close range inspection. Its ability to fly close to the terrain enables a thorough search for victims in a well‐defined sector. A smaller multicopter was used for inspection of the indoor environment. It is able for victim detection in collapsed buildings. Thus, autonomous functionality for precise localisation and positioning was developed to decrease the operator workload

Spectroscopic analysis of keratin endogenous signal for skin multiphoton microscopy

International audienceWe recorded one-photon excited fluorescence (1PEF) and two-photon excited fluorescence (2PEF) spectra of purified keratin from human epidermis, and determined the action cross section of this endogenous chromophore. We used this spectroscopic analysis to analyse multiphoton images of skin biopsies and assign the intrinsic fluorescence signals in the epidermis. We observed a good agreement between in situ and in vitro 2PEF spectra of keratin. This study provides a comprehensive characterization of the 2PEF signal of the keratins from the epidermis, and will be of practical interest for multiphoton imaging of the skin. © 2005 Optical Society of Americ

Reproducibility in the field: Transparency, version control and collaboration on the project panormos survey

Abstract Archaeological fieldwork is rarely considered reproducible in the sense of the ideal scientific method because of its destructive nature. But new digital technology now offers field practitioners a set of tools that can at least increase the transparency of the data-collection process as well as bring other benefits of an Open Science approach to archaeology. This article shares our perspectives, choices and experiences of piloting a set of tools (namely: ODK, Git, GitLab CE and R) which can address reproducibility of fieldwork in the form of an intensive survey project in western Turkey, and highlights the potential consequences of Open Science approaches for archaeology as a whole.</jats:p

A subaqueous hazard map for earthquake-triggered landslides in Lake Zurich, Switzerland

The awareness of geohazards in the subaqueous environment has steadily increased in the past years and there is an increased need to assess these hazards in a quantitative sense. Prime examples are subaqueous landslides, which can be triggered by a number of processes including earthquakes or human activities, and which may impact offshore and onshore infrastructure and communities. In the literature, a plenitude of subaqueous landslide events are related to historical earthquakes, including cases from lakes in Switzerland. Here, we present an approach for a basin-wide earthquake-triggered subaquatic landslide hazard assessment for Lake Zurich, which is surrounded by a densely populated shoreline. Our analysis is based on high-resolution sediment-mechanical and geophysical input data. Slope stabilities are calculated with a grid-based limit equilibrium model on an infinite slope, which uses Monte Carlo sampled input data from a sediment- mechanical stratigraphy of the lateral slopes. Combined with probabilistic ground-shaking forecasts from a recent national seismic hazard analysis, subaquatic earthquake-triggered landslide hazard maps are constructed for different mean return periods, ranging from 475 to 9975 years. Our results provide a first quantitative landslide hazard estimation for the lateral slopes in Lake Zurich. Furthermore, a back-analysis of a case-study site indicates that pseudostatic accelerations in the range between 0.04 and 0.08 g were needed to trigger a well-investigated subaqueous landslide, dated to *2210 cal. years B.P
