Age-Appropriate Programs: Best Practice: Effective programs are designed to match the developmental stages of the learner

Children and adults learn in completely different ways. Too often, however, children’s programs are developed from an adult’s perspective, rather than that of a child. The best children’s environmental education programs are designed with children’s abilities, developmental needs, interests, and learning styles in mind. Different programs should be created to appropriately meet the needs of different age groups and their respective cognitive development, attention spans, coordination abilities, interests, and ways of interacting with nature

Discover Mojave Outdoor World Activity Unit Curriculum

This document provides suggested activity outlines for each recreational unit as well as available resources, pertinent contacts, checklists, and activity assessments. Each unit is correlated with the themes identified by the Southern Nevada Agency Partnership Conservation Education and Interpretation Team. The Discover Mojave Outdoor World program introduces urban youth, ages 8-12, to outdoor recreation and environmental education. The program promotes the belief that outdoor recreation plays an important and positive role in the health and fitness of America’s youth. The program is patterned after the national Wonderful Outdoor World (WOW) program. WOW introduces urban youth and families to the outdoors and outdoor recreation through overnight camping experiences within the heart of their own community. With this approach, the program seeks to bring the excitement of camping and the environment directly into the neighborhoods and communities of the children most in need

Politik der Profession: Das Leitbild der Berlinischen Architektur

"Die beispiellose städtebauliche Erfassung des Berliner Zentrums in den letzten fünf Jahren hat zu einem charakteristischen Bild von Stadt geführt Diese Bild nimmt bereits in einer Reihe von Großprojekten Gestalt an. Es kann gezeigt werden, daß die herkömmliche Analyse von Investoreninteressen und Bodenverwertung nicht ausreicht, die Entstehung dieser gebauten Ordnung zu erfassen. Vielmehr kann in einer kultursoziologisch gerichteten Akteursanalyse der spezifische Einfluß professioneller Deutungsmuster und Weltbilder demonstriert werden. Die Wechselwirkung von urbanistischer Theorie und medialer Inszenierung hat die kulturelle Deutungsmacht von Architekten und Planern gegenüber ökonomischen, politischen, vor allem aber auch den marginalen sozialwissenschaftlichen Interventionen deutlich gemacht. In der 'negotiated order' der Stadtpolitik hat die Profession der Architekten als Mittler zwischen divergierenden Interessen eine eigenständige Politik treiben können. Dies kann anhand des Berliner Architekturstreites exemplarisch gezeigt werden." (Autorenreferat

The bisphosphonate zoledronic acid inhibits the growth of HCT-116 colon carcinoma cells and induces tumor cell apoptosis

Besides its preventive action on bone resorption the third generation bisphosphonate zoledronic acid (ZOL) has been shown to display potent inhibitory action on the formation of bone metastases of various human cancers. Recent research also indicates an antitumoral effect on primary tumors and visceral metastases. Here we investigate for the first time the effect of ZOL on the human colon carcinoma cell line HCT-116. ZOL strongly inhibited the proliferation and soft agar colony formation of HCT-116 cells and caused a G1 cell cycle arrest in a population of ZOL treated cells. This cell cycle arrest was accompanied by an induction of apoptosis via a caspase dependent mechanism. Activation of Caspases 3, 7, 8 and 9, cleavage of PARP as well as the release of cytochrome C into the cytosol were detected in HCT-116 cells treated with low micromolar concentrations of ZOL. The induction of the mitochondrial pathway of apoptosis was accompanied by a translocation of Bax into the mitochondria, Bid activation and a decrease of overall Bcl-2 expression. We also detected a cytosolic increase of apoptosis inducing factor (AIF), a trigger of caspase-independent apoptosis. Taken together, our data indicate a potent antitumoral and apoptosis inducing effect of ZOL on HCT-116 colon carcinoma cell

Neues Zuhause für Musikalien: Umzug des Deutschen Musikarchivs der Deutschen Nationalbibliothek von Berlin nach Leipzig

Im Dezember 2010 zieht das Deutsche Musikarchiv (DMA) von Berlin an den Standort der Deutschen Nationalbibliothek Leipzig. Mit dem DMA wird sich in Leipzig die zentrale nationale Sammlung von Musikalien und Tonträgern und das musikbibliografische Informationszentrum Deutschlands ansiedeln

Präparation von Ni-C-Multischichten und Mischsystemen mit dem PLD-Zweistrahlverfahren und Untersuchung der thermischen Stabilität der Schichtsysteme

The Pulsed Laser Deposition is an established method for the preparation of thin films and nm layer systems. In this work a cross beam PLD system is used as a special development for reduction of macro particle contamination in the growing layer. Two plasma plumes which overlap under a defined angle are produced on separated targets by two synchronized lasers. In the overlapping zone the direction of plasma expansion is changed by interaction of plasma particles. A diaphragm is used to guaranty that only the part of the plasma is deposited on the substrate that has changed the direction of expansion in the interaction zone. Detailed characterizations of plasma properties, deposition and growth conditions were carried out to demonstrate that cross beam PLD is an effective method to reduce macro particle contamination and allows layer growth under reduced energetic loading of the substrate. In the second part of this work cross beam PLD is used to produce Ni/C multilayers and artificial mixtures. The interest is focused on the mechanisms of layer disintegration and structure formation under thermal loading. Possible processes for layer disintegration are discussed on a theoretical background and verified in TEM examinations.Die Pulsed Laser Deposition ist ein etabliertes Verfahren zur Herstellung dünner Schichten im nm-Bereich. Das in dieser Arbeit verwandte PLD-Zweistrahlverfahren ist eine besondere Entwicklung zur Verringerung der Makropartikelkontamination der Schichten. Zwei synchronisierte Laser erzeugen auf zwei benachbarten Targets zwei Plasmafackeln, die unter einem bestimmten Winkel überlappen, was zu einer Änderung der Ausbreitungsrichtung des Palmas führt. Ein spezielle Blendenanordnung garantiert, dass nur der abgelenkte Teil des Plasmas auf dem Substrat abgeschieden wird, welches für die anfänglichen Plasmafackeln im Schatten liegt. Anhand einer umfangreichen Charakterisierung der Plasma-, Abscheide- und Schichtwachstumseigenschaften wird gezeigt, dass das PLD-Zweistrahlverfahren eine effektive Verminderung der Makropartikelkontamination der Schichten ermöglicht und dass das Schichtwachstum unter deutlich verringertem Energieeintrag im Vergleich zur konventionellen PLD erfolgt. Das Verfahren wird im zweiten Teil der Arbeit angewandt um Ni/C-Multischichten und künstliche Mischungen herzustellen. Das Interesse liegt hierbei auf den Mechanismen des Schichtzerfalls und auf den entstehenden Strukturen bei thermischer Behandlung metastabiler Schichtsysteme. Anhand theoretischer Betrachtungen werden die möglichen Prozess des Schichtzerfalls eingegrenzt und mittels TEM-Untersuchungen verifiziert

Discover Mojave Forever Earth Curriculum

The Discover Mojave Forever Earth program is more than a field trip to Lake Mead National Recreation Area (NRA). The program takes place aboard the Forever Earth, a floating environmental learning center. It is designed to give students the rare opportunity to study different facets of water in the desert—such as its characteristics and quality, the species that rely on it, its ability to change a landscape, and much more. This educational experience complements traditional classroom studies with engaging, participatory, on-site activities and support lessons based upon a solid framework for inquiry and discovery. On-site activities and the supporting lessons described herein align with Clark County School District curriculum and are correlated to Nevada State Science Standards and Clark County School District Curriculum Essentials Framework and Science Objectives. Pre-visit lessons prepare students for their trip, introducing important background concepts, key questions, and themes. Post-visit lessons follow up on and reinforce the on-site learning, and more importantly, encourage “big-picture” synthesis and options for stewardship
