An Evaluation of the Impact of Ignition Location Uncertainty on Forest Fire Ignition Prediction Using Bayesian Logistic Regression (Short Paper)
No full textThis study investigates the impact of location uncertainty on the predictive performance of Bayesian Logistic Regression (BLR) for forest fire ignition prediction in Austria. Historical forest fire ignitions are used to create a dataset for training models with the capability to assess the general forest fire ignition susceptibility. Each recorded fire ignition contains a timestamp, the estimated location of the ignition and a radius defining the area within which the unknown true location of the ignition point is located. As the values of the predictive features are calculated based on the assumed location, and not the unknown true location, the training data is biased due to input uncertainties. This study is set to assess the impact of input data uncertainty on the predictive performance of the model. For this we use a data binning approach that splits the input data into groups based on their location uncertainty and use them later for training multiple BLR models. The predictive performance of the models is then compared based on their accuracy, area under the receiver operating characteristic curve (AUC) scores and brier scores. The study revealed that higher location uncertainty leads to decreased accuracy and AUC score, accompanied by an increase in the brier score, while demonstrating that the BLR model trained on a smaller high-quality dataset outperforms the model trained on the full dataset, despite its smaller size. The study’s contribution is to provide insights into the practical implications of location uncertainty on the quality of forest fire susceptibility predictions, with potential implications for forest risk management and forest fire documentation
Romancı Yönüyle Herta Müller
No full textNobel Edebiyat ödülünü 2009 yılında kazanan Herta Müller, 1953 yılında Romanya'nın Almanca konuşulan Banat bölgesinde dünyaya geldi. Romanya'da Çavuşesku dönemini açıkça eleştirmesi nedeniyle Herta Müller kendi ülkesinde kitaplarının basılması yasaklandı. Herta Müller 1987 yılında Romanya'dan Almanya'ya göç etti. Yazarın hayatı, gizli polis teşkilatının ve Banat bölgesinin hayatındaki önemi, edebiyat dünyasındaki yeri ve sanatının günümüz için önemi araştırıldı. Yazarın şimdiye kadar yazmış olduğu "Der Fuchs war damals schon der Jäger", "Herztier", "Heute wäre ich mir lieber nicht begegnet" ve "Atemschaukel" adlı romanlarının ana sorunları, figürler, ana motifler, yapı özellikleri ve yazarın üslup özellikleri gibi altı başlık altında incelendi.Herta Müller, who was awarded the Nobel Prize in Literature in 2009, was born in Banat of Romania where German was spoken in 1953. Publication of her books in her own country was forbidden as she clearly criticised the period of Ceausescu in Romania. Herta Müller immigrated to Germany from Romania in the year of 1987. The life of the author, the importance of secret police service and the region of Banat on her life, her place in the literary world and the meaning of her art for today were searched. The novels she wrote up to now, namely "Der Fuchs war damals schon der Jäger", "Herztier", "Heute wäre ich mir lieber nicht begegnet" and "Atemschaukel", were examined under six titles like: Key Issues, Key Figures, Key Motifs, Structure Features and Author's Stylistic Features
"En tierras bajas" de Herta Müller: mirada crítica hacia las cicatrices de una infancia irrespirable
No full textThrough the look and narrative voice of a Romanian girl, the writer Herta Müller brings us closer with her first work – Niederungen (En tierras bajas) - to the still living scars of her own childhood in a small village in the region of Timisoara at the time of the dictatorship of Nicolae Ceausescu. This article attempts a critical approach to the recurring theme focused on the complaint of the country left behind by the author after her own experience of exile to West Germany in 1987. A critical analysis of this first work written by Müller in the German language brings us closer to her intercultural literature. The high quality of the literary production of this German-Romanian migrant writer was finally awarded in 2009 with the Nobel Prize for Literature.A través de la mirada y la voz narrativa de una niña rumana, la escritora Herta Müller nos acerca con su ópera prima Niederungen (En tierras bajas) a las cicatrices aún hoy vivas de su propia infancia en un pequeño pueblo ubicado en la región de Timisoara en la época de la dictadura de Nicolae Ceaucescu. Este artículo pretende una aproximación crítica a la recurrente temática centrada en la denuncia del país dejado atrás por la escritora tras su experiencia de exilio a la entonces Alemania occidental en el año 1987. Un análisis crítico de esta primera obra publicada por Müller en lengua alemana nos acerca a la literatura intercultural de la escritora migrante rumano-alemana cuya calidad y trayectoria literaria la hizo merecedora en 2009 del Premio Nobel de Literatura
Recall this Book 62: A Conversation with Jan-Werner Müller
No full textToday's guest is Princeton's Jan-Werner Müller, (Another Country: German Intellectuals, Unification and National Identity, A Dangerous Mind: Carl Schmitt in Post-War European Thought, Constitutional Patriotism) author of What is Populism? (2016) which explores how the identitarian logic of populism can come to lodge within democracies. Is the current success of the antidemocratic Right (in Hungary and Poland-and increasingly elsewhere in Europe as well) the product of "plutocratic populism"? Or is there some other more systemic maladjustment in Europe and America, whereby the ground rules for deliberative democracy have been skewed into a new stable shape, one that anti-democratic populist leaders have been able to capitalize on by borrowing from one another's dangerous playbooks

Osmia centaureae is in both sexes very similar to O. spinigera (Fig. 16). In contrast to the latter species, its preoccipital margin is not distinctly raised (Fig. 18), the inner margin of the apicalmost part of the fore tibial spur is usually slightly convex rather than concave (Fig. 20), the antenna is partly reddish-brown to orange in its apical half rather than uniformly dark (Fig. 16) and the apical margins of terga 1–2 are often more or less reddish-brown rather than entirely black. In addition, the female of O. centaureae differs from O. spinigera by the colour of the scopa and the pilosity of vertex, scutum and scutellum, which is yellowish-white even in fresh specimens rather than yellowish-red to yellowish-brown (Fig. 16). The male of O. centaureae lacks the dense tuft of hairs directed alongside the apicalmost part of the gonoforceps typical of O. spinigera (Fig. 24) and the indistinct and shallow punctation of the shagreened basal part of tergum 6 is almost imperceivable (Fig. 22) and thus even weaker than in O. spinigera.

Punctation of clypeus and supraclypeal area very dense without distinct interspaces; apical third of clypeus with very small punctures, which are about one third as large as the punctures on the basal two thirds of the clypeus and about half as large as the punctures on the supraclypeal area. Face covered with white pilosity, which is rather dense and long on frons, paraocular area and posterior margin of vertex but only sparse and usually short on clypeus, supraclypeal area and vertex. Anterior side of antennal segments 7–11(12) usually more or less reddish-brown (Fig. 16). Mesosoma: Axilla spined. Posterior margin of scutellum flattened, reaching in profile well beyond metanotum. Punctation of scutum and scutellum very dense with interspaces usually not exceeding the diameter of half a puncture except for the lateral part of the scutum where the punctation is often more scattered. Punctation of mesepisternum very dense without distinct interspaces. Scutum moderately densely and scutellum very densely haired, longest hairs on scutum about 5x as long as the diameter of one puncture. Pilosity of mesepisternum long and rather dense, partly hiding the sculpture of the integument. Pilosity of scutum and scutellum yellowish-white, of mesepisternum white (Fig. 16). Tegula dark reddish-brown to black. Inner margin of apicalmost part of fore tibial spur slightly convex (Fig. 20). Metasoma: Punctation of terga 1–3 very dense with interspaces rarely reaching the diameter of one puncture, of terga 4–6 even denser with interspaces not exceeding the diameter of half a puncture. Apical margins of terga impunctate and often more or less reddish-brown. Terga 1–6 with white apical hair bands, which are medially interrupted on tergum 1 and often also on tergum 2 (Fig. 16). Scopa yellowish-white (Fig. 16). MALE: Body length 7–9.5 mm. Head: Head about 0.9x long as wide. Distance between lateral ocellus and preoccipital margin 2.6–2.9x as long as ocellar diameter. Second segment of labial palpus about 2.6x as long as first segment. Maximal width of genal area about 0.5x as long as maximal width of compound eye. Mandible twotoothed. Preoccipital margin sharp but not distinctly raised. Frons, paraocular area, supraclypeal area and clypeus covered with dense white pilosity. Antennal segments (5)6–13 more or less yellowish-brown to orange. Mesosoma: Axilla spined. Posterior margin of scutellum flattened, reaching in profile well beyond metanotum. Punctation of scutum, scutellum and mesepisternum as in the female. Scutum and scutellum covered with dense greyish-white pilosity. Pilosity of mesepisternum long, dense and white. Tegula dark reddish-brown to black. Inner margin of apicalmost part of fore tibial spur straight to slightly convex. Metasoma: Punctation of terga 1–5 very dense with interspaces rarely reaching the diameter of one puncture. Tergum 6 basally densely shagreened and with very weak and almost imperceivable punctation (Fig. 22). Preapical margin of tergum 6 with long spines (Fig. 22).

Apical margin of sternum 5 medially with wide and rather deep emargination, which is densely beset with yellowish hairs (Fig. 17). Sternum 6 distinctly concave, its apical margin evenly rounded (Fig.17). Punctation of sterna 2–4 moderately dense, interspaces only rarely exceeding the diameter of two punctures (Fig. 17). Apical margins of sterna 2-4 beset with whitish hairs, which are laterally longer and denser than medially (Fig. 17). Apical third of gonoforceps with numerous erect white hairs (Fig. 24). Distribution. Known only from a restricted area, which extends from the southeastern border of the Dead Sea in Jordan over the Jordan Valley to northernmost Israel. At five localities in Israel and Jordan, O. centaureae was collected together with O. spinigera on the same day indicating syntopic occurrence of these two closely related species within the distribution range of O. centaureae. Pollen hosts. Oligolectic on Asteraceae (based on 28 pollen loads from 9 different localities in Israel and Jordan and on field observations). Twenty-six pollen loads were pure loads of Centaurea pollen, while the other two were mixed loads of Centaurea and thistle pollen, suggesting that O. centaureae probably restricts pollen harvesting to the subfamily Carduoideae. Nesting biology. Unknown. Etymology: The specific name refers to the species’ most important pollen host, Centaurea (Asteraceae, Carduoideae).Published as part of Müller, Andreas, 2018, Palaearctic Osmia bees of the subgenus Hoplosmia (Megachilidae, Osmiini): biology, taxonomy and key to species, pp. 297-329 in Zootaxa 4415 (2) on pages 303-304, DOI: 10.11646/zootaxa.4415.2.4, http://zenodo.org/record/124199

Human impact on the vegetation of limestone cliffs in the northern Swiss Jura mountains
No full textCliffs provide unique habitats for many specialised organisms, including
chamaephytes and slowly growing trees. Drought, high temperature
amplitude, scarcity of nutrients and high insolation are general characteristics
of exposed limestone cliff faces. The vegetation of limestone cliffs in the
Swiss Jura mountains consists of plants of arctic-alpine, continental and
Mediterranean origin. Several populations exhibit relicts from post- or
interglacial warm or cold climatic periods. Grazing goats and timber
harvesting influenced the forests surrounding the limestone cliffs in northern
Switzerland for many centuries. During the twentieth century, however, these
traditional forms of forest use were abandoned.
In recent years, rock climbing enjoys increasing popularity in mountain
areas at low elevation, where this sport can be performed during the whole
year. The limestone cliffs of the Jura mountains provide unique opportunities
for sport climbers. As a consequence, more than 2000 climbing routes with
fixed protection bolts have been installed on 48 rock cliffs in the region of
Basel, Switzerland.
Overgrowing forest, due to the abandonment of forestry and damages
due to recreational activities including rock climbing reduce the quality and
size of the cliff habitats. In my dissertation, I examined quantitative, spatial
and temporal patterns of human impacts on the cliff flora and on the genetic
population structure of two plant species on isolated cliffs in the Jura
mountains of northern Switzerland.
The assessment of plant cover and species density at various distances
from frequently used climbing routes in the region showed that plant cover
was significantly reduced at the base of climbing routes. Furthermore, species
density (number of species per m2) at the cliff base as well as plant cover and
species density on the cliff face tended to increase with distance from the
route.
The comparison of the vegetation at the cliff base and on the cliff face of
five frequently climbed cliffs with that of seven unclimbed cliffs indicated that
rock climbing significantly altered the plant composition. Specialised rock
species occurred less frequently on climbed cliffs than on unclimbed cliffs.
At the Gerstelflue, a popular recreational climbing site with rock climbing
activities since more than 40 years, plant cover and species density (number
of species per m2) were reduced in climbed areas. Rock climbing also
reduced the density (number of individuals per m2) of forbs and shrubs,
whereas the density of ferns tended to increase in climbed areas. In addition,
rock climbing caused a significant shift in plant species composition and
altered the proportions of different plant life forms.
Species diversity and cover of lichens, and possible associations
between lichens and lichen-feeding land snails were assessed in climbed and
unclimbed areas of 10 isolated cliffs. Total lichen species density was not
correlated with the complexity of the rock surface, climbing frequency and age
of the climbing route. The species density of epilithic lichens was lower along
climbing routes than in unclimbed areas, whereas no difference in species
density of endolithic lichens was found between climbed and unclimbed
areas. Furthermore, climbed and unclimbed areas did not differ in total lichen
cover. The dissimilarity of the lichen communities between climbed and
unclimbed areas increased with increasing climbing intensity on the focal
route in climbed areas, but not with the age of the climbing route. Within cliffs,
plots along climbing routes harboured fewer snail species and individuals than
plots in unclimbed areas.
The effects of forestry practices on the species richness and abundance
of vascular plants on the face, at the base and on the talus have been
investigated by comparing two different forestry practices (clear-cutting and
shelter tree cutting) with forest reserve (i.e. no management in the past 80
years)) on three cliffs. Plant species density and vegetation cover was higher
in the shelter-cut areas than in the forest reserves on the talus as well as at
the cliff base. Clear-cut areas showed a higher vegetation cover than forest
reserves on the talus. Shelter-cut areas harboured a larger proportion of
plants with high light demands and plant indicator species showed a higher
mean light score than in clear-cut areas and forest reserves.
The analysis of time-series of air photographs taken between 1951 and
2000 at six cliffs revealed an increase in tree cover from 60% to 85% between
1951 and 1964 after which the increase levelled off. The increase in tree
cover showed a distinct spatial pattern. It was significant in the talus and on
the cliff face, but not on the plateau (at the top of the cliffs).
Possible effects of isolation and the presumed colonisation history of
cliffs as well as of anthropogenic activities on the genetic population structure
of two plant species with different life-histories were assessed using RAPDpolymorphisms.
Fourteen populations of Draba aizoides L. and 12 populations
of Melica ciliata L. living on isolated limestone cliffs were examined. Analysis
of molecular variance revealed a high among-population variation of each
27% in the gene pools of both species. A clear isolation-by-distance pattern
and a separation of populations from the Jura mountains and the Alps were
found in D. aizoides. This provides evidence for glacial relict endemism in this
species, resulting from nunatak survival in the Jura mountains. In M. ciliata,
UPGMA-analysis showed clusters of plant populations growing on cliffs with
castles with shared historical incidents, indicating zoochorical dispersal
related to human settlements.
The various studies emphasise the uniqueness and vulnerability of the
limestone cliff ecosystem of northern Switzerland. Protection measures in
several fields of activity are needed to preserve the unique relict vascular
plant, lichen and animal communities. Adequate management actions should
be developed and implemented. Actions should particularly be directed to
cliffs with numerous arctic-alpine plant species to protect them from mechanic
disturbances by sport climbing and hiking. The prohibition of sport climbing on
cliffs with a high number of specialised plant or animal species and the
establishment of climbing-free protection zones in popular areas are the most
effective and adequate measures in this context. However, any management
plan should include a comprehensive information campaign to show the
potential impact of intensive sport climbing on the specialised flora and fauna
and to increase the compliance of these measures by the climbers. Forestry
practices that keep the supply of light on a high level at the lower parts of the
cliffs are required to preserve the relict plant species. Selective thinning on the
talus results in relatively large plots with good light conditions and therefore
promotes the rare, relict plant species with high light demands. Self
evidentely, forestry actions and climbing prohibitions should be executed in
coordination. Another measure to manage the lower parts of cliffs could be to
use them as temporal pastures for goats. Finally, the preservation of
mediaeval sites also connotes the conservation of plant species introduced
into the area during the time of human activities
Herta Müller
No full textTwo languages—German and Romanian—inform the novels, essays, and collage poetry of Nobel laureate Herta Müller. Describing her writing as “autofictional,” Müller depicts the effects of violence, cruelty, and terror on her characters based on her own experiences in Communist Romania under the repressive Nicolae Ceauşescu regime.
Herta Müller: Politics and Aesthetics explores Müller’s writings from different literary, cultural, and historical perspectives. Part 1 features Müller’s Nobel lecture, five new collage poems, and an interview with Ernest Wichner, a German-Romanian author who has traveled with her and sheds light on her writing. Parts 2 and 3, featuring essays by scholars from across Europe and the United States, address the political and poetical aspects of Müller’s texts. Contributors discuss life under the Romanian Communist dictatorship while also stressing key elements of Müller’s poetics, which promises both self-conscious formal experimentation and political intervention.
One of the first books in English to thoroughly examine Müller’s writing, this volume addresses audiences with an interest in dissident, exile, migration, experimental, and transnational literature
