In order to determine the spatial extension and the characteristics of permafrost within alpine talus slopes, two sites located in the western part of the Swiss Alps were studied using borehole ...drilling and electrical resistivity tomography (ERT) profiles. Three boreholes were drilled along an upslope–downslope transect in both talus slopes. In both sites, frozen sediments are present only in the two lowest boreholes, whereas the upper borehole does not present ice. This stratigraphy is confirmed by ground temperatures registered in the boreholes. In each site, three upslope–downslope ERT profiles were crossed with five, respectively four horizontal ERT profiles. All the upslope–downslope profiles show a difference in resistivities between the upper and lower parts of the slope, where a large resistive body with values higher than 35
kΩm is present. In the uppermost part of the profiles, the resistivities are lower than 10–15
kΩm. The borehole data allowed the stratigraphy obtained from the ERT inverted profiles to be validated, with regards to the distribution of frozen sediments as well as the depth of the detected structures. The results confirm that, in the two studied sites, permafrost is present in the lower sections of the talus slopes, whereas it is absent in the upper parts. Finally, the analysis of the talus structure showed that the permafrost stratigraphy, and in particular the ice content, may be an important element of interpretation of the palaeoclimatic significance of an alpine talus slope.

ABSTRACT
2D electrical resistivity tomography has been applied within a mountain permafrost environment to assist in ice location. In the context of climate change, a warming process could partially ...thaw this permafrost and thereby increase the risk of slope instabilities. The extent and location of permafrost are therefore of considerable interest to civil engineers.
The most challenging aspect of resistivity surveys on mountain permafrost concerns the surface layer, which mainly consists of large blocks with air voids. To overcome the very poor electrical contact, long steel stakes and sponges soaked in salt water are used as electrodes. Nevertheless, only a weak current can be injected. Another challenging aspect is the high resistivity contrast between frozen and unfrozen material, which makes inversion and interpretation difficult and problematic. In order to assess whether features at depth, indicated by the data, are real or are artefacts of the inversion process, a special inversion algorithm was applied to process depth of investigation (DOI) index maps. This method carries out two inversions of the same data set using different values of the reference resistivity. The two inversions give the same resistivity values in areas where the data contain information about the resistivity of the subsurface. On the other hand, the final result depends on the reference resistivity in areas where the data do not constrain the model.
As can be deduced from field data from the Swiss Alps and the Jura Mountains, this methodology prevents over‐interpretations or misinterpretations of inversion results in mountain permafrost studies. From the DOI calculations, it is evident that little reliable information on the bedrock under the massive ice can be obtained and that the resistivity within the high resistivity zones cannot be determined accurately. The DOI map also helps to explain the occurrence of erratic and non‐geological structures at depth and indicates to what depth an inverted resistivity profile can provide results.

Artiklis vaadeldakse eesti vaatama-verbi ja selle vene ning ukraina vastete sihilisust. Põhieesmärk on uurida, kui regulaarsed on korpuse andmetel ‘vaatama’ transitiivsed ehk sihilised ja ...intransitiivsed ehk sihitud mallid eesti ja kahes idaslaavi keeles. Kuna vene ja ukraina keeles on enamikul verbidest olemas aspektipaariline, uuritakse artiklis eesti vaatama imperfektiivset ja perfektiivset vastet vene ja ukraina keeles eesmärgiga kontrollida, kumba verbilekseemi kasutatakse transitiivselt potentsiaalselt sagedamini. Korpusepõhine uuring kinnitas, et verbi ‘vaatama’ sihilisus võib keeliti oluliselt erineda. Sama meetodit rakendades selgus, et vene ja ukraina keeles on nii perfektiivse kui ka imperfektiivse ‘vaatama’ sihilisus oluliselt väiksem kui eesti vaatama oma. Seejuures kasutatakse ukraina ja vene keeles perfektiivset verbi transitiivselt mõnevõrra sagedamini kui selle imperfektiivset paarilist. *** On the transitivity of the verb ‘watch’/’look’ in Estonian, Russian and Ukrainian *** The article studies the transitivity of the Estonian verb vaatama ‘watch, look’ and its Russian and Ukrainian equivalents. The aim is to determine how regular the transitive and intransitive patterns of ‘watch, look’ are in Estonian and two East Slavic languages. Since in Ukrainian and Russian most verbs have an aspectual pair, both the imperfective and perfective counterparts of Estonian vaatama were examined, in order to determine which verb lexeme is used transitively potentially more often. The corpus-based study confirmed that the transitivity of the verb ‘watch, look’ can vary significantly between languages. Applying the same method, it was found that the Russian and Ukrainian equivalents of Estonian vaatama have a significantly lower degree of transitivity. However, in Ukrainian and Russian the perfective verb is used transitively somewhat more often than its imperfective counterpart. The findings of the study indicate the importance of language-specific aspectual lexical semantics in determining the degree of transitivity and could be taken into account while teaching Estonian as a second or a foreign language and compiling dictionaries for language learners.
I denna studie undersöker vi vilka kognitionsverb sverigesvenska och finlandssvenska studenter och handledare använder i akademiska handledningssamtal och i vilken omfattning de olika verben används. ...Materialet består av svenskspråkiga ämnes- och språkhandledningssamtal som spelats in vid universitet och högskolor i Sverige och i Finland. Resultatet av den kvantitativa och kontrastiva analysen visar att antalet och andelen kognitionsverb är högre i det sverigesvenska materialet. I båda materialsamlingarna använder handledarna fler kognitionsverb än studenterna. De finlandssvenska studenterna bidrar dock med fler kognitionsverb än de sverigesvenska studenterna. I analysen noteras vissa nyansskillnader vad gäller vilka semantiska fält som betonas och förekomsten av specifika kognitionsverb.

Zusammenfassung
Die Geschichte einer Erkrankung und deren Behandlung zu kennen, ist immer lehrreich und hilft, Zusammenhänge besser zu verstehen. Es zeigt auch, welche unglaublichen Vorleistungen ...notwendig waren, um Patienten heute in der für uns gewohnten Art zu behandeln. Dieser vorliegende Artikel versucht, die Spinalkanalstenose aus historischer Sicht zu beleuchten und diejenigen Wegbereiter zu benennen, die zum Verständnis der Epidemiologie, Anatomie, Pathogenese, Klassifikation und Diagnostik der Spinalkanalstenosen beigetragen haben. Darüber hinaus sind die Bemühungen von Wissenschaftlern und Klinikern zu würdigen, die in den letzten sieben Jahrzehnten an der Entwicklung der Therapie der lumbalen Spinalkanalstenose mitgewirkt haben.
