Farm Forestry in the Black Forest Southern Nature Park from a Socio-Political Point of View

In this study the interactions between forest management and the preservation of rural structures, as well as the economic implications should there be a shut-down of silvicultural activities in the small-scale private forestry of the Southern Nature Park of the Black Forest in Germany, are examined. The jobs, which are connected to the production of wood and the quality of the landscape, are characterized and projected on the region as far as possible. The creation of value by owners managing forests for production is demonstrated for the area of investigation. In combination with estimated average monetary values for the infrastructural benefits of the forests, scenarios point out the consequences of management as well as of a shut-down of the small-scale private forests. Finally, the paper explores whether it is it is appropriate to extend the meaning of the term 'Environmentally Sound Forest Management' beyond the conventional sense of forest functions, and to an holistic approach which integrates the people as well as forests and other landscape features. If an holistic approach is adopted, a redefined model of the mixed farm forest enterprise, which pursues many targets in the same area, must be developed. In this way, it seems possible to solve conflicts regarding land-use in rural areas and to achieve desirable socio-political development

The Untiring Pen: Avienus’ Construction of a Voice

The fact that Avienus (ca. 305-375), murky and hard-to-handle translator and poet of constellations ('Arati Phaenomena'), mountain ranges ('Descriptio Orbis Terrae') and coastlines ('Ora Maritima'), is chiefly a translator of Greek originals has benefited him little in terms of scholarly interest. Yet his work shows some remarkable characteristics which both highlight his own particular style and assign him a place in late antique poetics. The aim of this paper is to see some of these broader poetical characteristics at work within a manageable section of his work: i.e. the way in which Avienus creates a literary 'persona'. We will be looking not only at the specific voice that is created, but also at the way this is achieved and the impact this has upon the ensuing didactic narrative. In several ways, we will see, Avienus’ pen was soaked in the ink of memory.Il fatto che Avieno (ca. 305-375), oscuro e complesso traduttore e poeta di costellazioni ('Arati Phaenomena'), catene montuose ('Descriptio Orbis Terrae') e coste ('Ora Maritima'), sia principalmente un traduttore di originali greci gli è valso uno scarso interesse da parte degli studiosi. Ciononostante, il suo lavoro mostra alcune caratteristiche notevoli che consentono allo stesso tempo di metterne in evidenza lo stile e di assegnargli un ruolo nella poetica della tarda antichità. Lo scopo di questo contributo è indagare alcune di queste caratteristiche poetiche generali in una parte definita della sua opera: il modo in cui Avieno crea una persona letteraria. Si osserverà non soltanto come la specifica voce viene creata, ma anche come si arriva a questo risultato e l’impatto che ciò ha sulla conseguente narrazione didattica. La penna di Avieno, come si vedrà, è stata intinta in molti modi nell’inchiostro della memoria

Isolation of equine endothelial cells and life cell angiogenesis assay

Arterial or venous thromboses are frequent clinical complications with the risk of fatal progression. Recent studies suggest the disruption of angiogenesis in the course of thrombus resolution as the underlying pathomechanism. Very similar to the situation in human patients, equine vessels have been described to be particularly susceptible to thrombosis. In contrast to humans, equine donors are readily available to obtain organs and tissues for isolation of endothelial cells. Objective of this study was to isolate equine endothelial cells and develop an angiogenesis assay from primary cultures. Macrovascular endothelial cells were obtained from jugular veins and carotid arteries of nine horses, one of which suffered from inflammatory processes. After enzymatic isolation, the cells were incubated in different selective primary media. Phenotypic identification of endothelial cells was accomplished by morphology and positive staining to von Willebrand factor. The reliable, inexpensive, and standardized combination of methods presented here resulted in pure endothelial cultures for angiogenesis assays that can be used in any cell culture laboratory. Inverted phase microscopy and life cell imaging was used to characterize the stages of the angiogenic cascade of the endothelial cells. Life cell imaging gave new insights into the in vitro formation of capillary like structures including exocytosis of microparticles from endothelial cells before integration into the three-dimensional structure. We hypothesize that a specific population of endothelial cells showing a highly active migration pattern in life cell imaging might play a role in the resolution of thrombosis

Frühe mathematische Bildung - Ziele und Gelingensbedingungen für den Elementar- und Primarbereich

Schon kleine Kinder nutzen die Mathematik: beim Tischdecken, beim Spielen mit Bauklötzen oder beim Teilen von Süßigkeiten. Um die kindlichen Lern- und Entwicklungsprozesse in der Auseinandersetzung mit Mathematik begleiten und fördern zu können, müssen pädagogische Fach- und Lehrkräfte solche mathematischen Situationen erkennen und zu nutzen wissen. Um sie dabei zu unterstützen, stellt die Stiftung „Haus der kleinen Forscher“ verschiedene Angebote im Bereich Mathematik zur Verfügung. Der Konzeption und dem Ausbau der Stiftungsangebote im Bereich der frühen mathematischen Bildung ging erneut eine fachliche Fundierung des Themenbereichs voraus. In deren Rahmen erarbeiteten Fachexpertinnen und -experten eine Expertise zu den Zieldimensionen mathematischer Bildung für Kinder und für pädagogische Fach- und Lehrkräfte. Der vorliegende Band stellt diese Expertise vor und gibt einen Überblick über die Umsetzung der Empfehlungen in die inhaltliche Entwicklung der mathematischen Stiftungsangebote. (DIPF/Orig.)
