Mentoring of newly qualified teachers. A bilateral comparison between Germany and Finland

2017

Mentoring stellt in der Begleitung von in den Beruf einsteigenden Lehrpersonen eine international gängige Praxis dar. Ausgehend von theoretischen und empirisch fundierten Annahmen wird in diesem Beitrag der Ansatz der practice architectures genutzt, um Formen des Mentorings in Deutschland und Finnland im Hinblick auf länderspezifische Verständnisse vom Berufseinstieg von Lehrpersonen und deren Professionalisierung zu untersuchen. (DIPF/Orig.) Internationally, mentoring is a well-recognized practice in supporting newly qualified teachers. Based on theoretical and empirical understanding, this paper compares mentoring practices in two countries: Germany and Finland. The theoretical framework …

Transgenerationale Effekte belastender Kindheitserlebnisse auf die Borderline-Symptomatik von Jugendlichen

2014

Einleitung: Bisherige Forschungsergebnisse belegen substantielle Zusammenhänge zwischen dem Erleben von Missbrauchs- und Misshandlungserfahrungen in der Kindheit und der Entwicklung der Borderline Persönlichkeitsstörung im Erwachsenenalter. Die Frage nach transgenerationalen Effekten belastender Kindheitserlebnisse sowie möglicher intermittierender Variablen wird hingegen kontrovers diskutiert. Zudem beschäftigten sich bislang wenige Studien mit der Entwicklung von Borderline Symptomen im Jugendalter. An diesen Wissenslücken ansetzend, untersuchen wir die spezifischen Effekte belastender Kindheitserfahrungen von Eltern auf Borderline-Persönlichkeitsmerkmale der Folgegeneration sowie möglich…

Quantitative relations between different concentrations of micro- and macroelements in mosses and lichens: the region of Opole (Poland) as an environ…

2010

We examined the concentration of selected metals: Al, Mn, Fe, Cu, Zn, Cd and Pb, as well as activity of 137Cs in samples of moss and lichen, collected in the area surrounding Bory Stobrawskie, a wood complex situated in southern Poland. The concentration of metals was determined by atomic absorption spectrometry. The activity of 137Cs was determined by gamma spectrometry. We used these results, as well as results published in the literature, to determine the correlation between the concentration of analytes in lichens and in mosses. The analysis of the function ln(cx,moss) = lna + bln(cx,lichen) indicated with high degree of certainty that the concentration levels of analytes accumulated in…

Fungi and Sediments

2000

Fungi are saprophytic organisms that can form lichens in symbiosis with an alga. Along with lichens, they excrete large quantities of organic acids, contributing to rock dissolution and neoformation of crystals, mainly oxalates and carbonates. Fungi contribute to the accumulation of manganese and iron as desert varnish and play a major role in the calcium cycle inside calcretes and carbonate soils in arid zones. Fungi constitute an important part of calcified filaments found in calcretes. They are covered with calcium oxalate crystals, which can transform into calcite during early diagenesis. They can also precipitate needle-fiber calcite, a common form of CaCO3 found in soils and calcretes…

New records of lichens and lichenicolous fungi from Latvia, with a list of lichenicolous fungi reported from Latvia

2019

Four species of lichen-forming fungi (Calicium pinastri, Chaenotheca laevigata, Lecania croatica and Pycnora praestabilis) and two lichenicolous fungi (Arthrorhaphis aeruginosa and Chaenothecopsis epithallina) are reported as new for Latvia. The first comprehensive list of lichenicolous fungi in Latvia is also presented, including their hosts and distribution in Latvia (northern Europe).

A combined treatment regimen for desquamative gingivitis in patients with oral lichen planus

2007

Background:  Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). Methods:  A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. Results:  PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be re…

Lichen sclerosus Mistaken for Sexual Abuse – Prevention of Victimization

2014

This case report describes the forensic examination of 7 girls aged between 4-11 years with suspected sexual abuse. The children had been reported by local pediatricians, hospital physicians or authorities such as the youth welfare office and police due to mucosal changes in the anogenital area. All children presented with a clearly delimited, porcelain-like white discoloration of the skin in the anal and genital area with atrophic conversion to parchment-like skin. The markedly vulnerable skin exhibited very different manifestations of hemorrhagic dermal and mucosal defects in the area of the labia, the clitoris, the perineum and the perianal region. The hymen was intact in all cases. The …

Chlorophyll a Fluorescence Emission, Xanthophyll Cycle Activity, and Net Photosynthetic Rate Responses to Ozone in Some Foliose and Fruticose Lichen …

2000

The lichens Parmelia quercina, Parmelia sulcata, Evernia prunastri, Hypogymnia physodes, and Anaptychia ciliaris were exposed to ozone (O3) in controlled environment cuvettes designed to maintain the lichens at optimal physiological activity during exposure. Measurements of gas exchange, modulated chlorophyll (Chl) fluorescence, and pigment analysis were conducted before and after exposure to 300 mm3 (O3) m−3, 4 h per d for 14 d. No changes in the efficiency of photosystem 2 (PS2) photochemistry, the reduction state of QA, or the electron flow through PS2, measured by Chl fluorescence, were detected in any of the five lichen species studied. Additionally, neither photosynthetic CO2 assimila…
