teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...
Song in songbirds is widely thought to function in mate choice and male–male competition. Song is also phenotypically plastic and typically learned from local adults; therefore, it varies across geographical space and can serve as a cue for an individual’s location of origin, with females commonly preferring males from their respective location. Geographical variation in song dialect may reflec...

The effects of fish farming on bacterial density, biomass, community structure and their possible link to antibiotic resistance have been investigated in coastal sediments of the Ligurian Sea (Western Mediterranean). The top 2 cm of the sediment under a fish farm and control areas were analysed during summer 2000. Bacterial density and biomass were three folds higher (up to 3 10 cells/g and 260...
Deciphering the sources of eolian dust on the Chinese Loess Plateau (CLP) is fundamental to reconstruct paleo-wind patterns and paleo-environmental changes. Existing datasets show contradictory source evolutions of eolian dust on the CLP, both on orbital and tectonic timescales. Here, the silicate Sr and Nd isotopic compositions of a restricted grain size fraction (28-45 μm) were measured to tr...
a r t i c l e i n f o Fire is one of the most important natural disturbances in the coniferous forests of the US Rocky Mountains. The Rocky Mountains are separated by a climatic boundary between 40° and 45° N, which we refer to as the central Rocky Mountains (CRM). To determine whether the fire regime from the CRM was more similar to the northern Rocky Mountains (NRM) or southern Rocky Mountain...
Vrgada Island is situated in the central part of eastern Adriatic coast. Upper Cretaceous limestones crop out on surface and Pleistocene sediments cover them some parts island. In this study we focus a coastal cliff elongated N – S direction, northern Aeolian-alluvial deposits, which are 12.5 m thick have been analysed. Three different facies succession described. Lowermost A has strong aeolian...
Owen, L.A. 1989. Neotectonics and deformation in the Karakoram Mountains and Nanga Parbat Himalaya. In: N.-A. Momer and J. Adams (Editors), Paleoseismicity and Neotectonics. Tectonophysics, 163: 227-265. The Karakoram Mountains and the Nanga Parbat Himalaya are one of the most rapidly rising mountain areas in the world with uplift rates in the order of 2 mm/yr. Large-scale regional warping is t...
