Frühe Hilfen - Frühintervention und STEEP
No full textDas Thema Frühe Hilfen für Familien mit Kindern von 0 bis 3 Jahren besitzt zurzeit eine große Aktualität – nicht zuletzt durch spektakuläre Fälle von Kindesmisshandlung und -vernachlässigung. Die Frage, wie hoch belastete Familien frühzeitig erreicht werden und wie geeignete Hilfs- und Unterstützungsangebote für sie aussehen können, wird von der Fachwelt und aktuell auch in der Politik auf Landes- und auch Bundesebene diskutiert. Im Department Soziale Arbeit der Fakultät Wirtschaft und Soziales an der HAW Hamburg wird derzeit zum Thema Frühe Hilfen gearbeitet und geforscht. In Zusammenarbeit mit Trägern aus der Praxis der Jugendhilfe in Hamburg und in der Bundesrepublik wurden Frühe Hilfen – und hier im Besonderen das Frühinterventionsprogramm STEEP – in der Praxis implementiert und durch Begleitforschung evaluiert. Mit dem STEEP-Programm kommt dabei ein bereits 1987 in den USA vorgestelltes Frühinterventionsprogramm zum Einsatz, das aus den Ergebnissen langjähriger Forschungsarbeit entwickelt wurde und dessen Wirksamkeit dort in aufwändigen Studien belegt werden konnte.
Der Aktualität des Themas Frühe Hilfen wird mit diesem Heft von standpunkt : sozial Rechnung getragen. Frühe Hilfen – besonders aber das STEEP-Programm – werden in Theorie und Praxis vorgestellt. Träger und Einrichtungen, die ganz konkret vor Ort arbeiten, berichten von ihren Erfahrungen.
Die beiden einleitenden Beiträge bieten die Gelegenheit, das STEEP-Programm kennen zu lernen. Die Begründer von STEEP, Martha Erickson und Byron Egeland, stellen das Programm vor und berichten über die Arbeit mit STEEP in unterschiedlichen Settings bzw. Einrichtungen in den USA. (Dieser Beitrag ist in der Originalfassung in englischer Sprache abgedruckt.) In einem weiteren Beitrag stellen wir das STEEP-Programm dann kurz in deutscher Sprache vor. Über die mit dem Programm verbundene Forschungsarbeit an der HAW informiert im Anschluss Gerhard Suess.
Es folgen Berichte aus der Praxis. Sr. Frumentia Maier stellt die Implementierung von STEEP in den Häusern des Lebens (Offenburg) dar. Birgit Maschke berichtet über die Arbeit zur Förderung der Frühen Hilfen im Kreis Herzogtum Lauenburg. Ute Dorczok und Michael Koglin informieren über die Arbeit in den Einrichtungen des Abendroth-Hauses und der Alida-Schmidt-Stiftung. Den Abschluss bildet der Beitrag von Evelyn Metzen von der Körber-Stiftung. Die Körber-Stiftung hat STEEP 2006 mit einem Ideenpreis ausgezeichnet und fördert seitdem die Verbreitung von STEEP in der Praxis, bei Experten und Multiplikatoren

Die Bohlen-Pierce-Klarinette. Theoretische Aspekte und zeitgenössische Anwendungen
No full textRepertoire in Bohlen-Pierce (BP) tuning has grown significantly since the debut of BP clarinets in 2008. Literature specifically dedicated to the BP clarinet, on the other hand, is still rare. Practice-led research conducted by the author provides useful materials about the BP soprano and tenor clarinets, such as contemporary playing techniques or acoustical conditions. The current state of repertoire is shown; exemplary analyses of compositions featuring one or more BP clarinets are given. A new BP specific notation is introduced; it has been developed from a practical point of view and has gained great acceptance among musicians performing in BP. Beside using BP as the (only) tuning system in compositions, it is also possible to combine BP with other scales to achieve effects of extended tonalities or rich microtonal structures. Multiphonics as a very popular phenomenon in contemporary woodwind music are highlighted, providing fingering charts and notational suggestions for both BP soprano and BP tenor clarinets. The theoretical idea of a BP third-tone scale (39div3) is transferred into practice by providing fingering charts and practical advice to performers and composers. I hope that this thesis can give inspiration and advice to those motivated to compose for and perform on BP clarinets, and that BP clarinets will gain the popularity they deserve in contemporary music performance. The BP clarinet and its growing repertoire may widen the range of expression of dedicated clarinet players
Factors Affecting Gingival Excess, Altered Passive Eruption and Recession in the Mandibular Anterior and Premolar Sites
No full textAbstract FACTORS AFFECTING GINGIVAL EXCESS, ALTERED PASSIVE ERUPTION AND RECESSION IN THE MANDIBULAR ANTERIOR AND PREMOLAR SITES By William F Bohlen, D.M.D. A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University. Virginia Commonwealth University, 2010 Major Director: Thomas Waldrop, DDS, MS Program director, Department of Periodontics, Virginia Commonwealth University AIM: The aim of this study was to determine the factors affecting gingival excess, altered passive eruption and recession. METHODS: 100 subjects were examined clinically and models of their mandible were fabricated. Demographic, periodontal and cast measurements were recorded for each subject. Measurements were made on casts with digital calipers and included clinical crown length, clinical crown width, papillary height and gingival width. The W:L ratio was calculated and the proportion compared to the maxillary arch ideal of .80. Values greater than .80 were used as a cutoff point for defining gingival excess. Measures of periodontal health were also examined and included probing depths, clinical attachment loss and bleeding on probing. Other patient variables examined were history of orthodontics, presence of occlusal and incisal wear, presence of parafunctional habits, subjective appearance of gummy smile and biotype. RESULTS: The mean W:L ratio was found to be 79.6 %. Tooth type (p\u3c0.001), gender (p\u3c0.0237) and biotype (p\u3c0.0081) were found to significantly contribute to a W:L ratio \u3e.80. There was a significant correlation between the subjective appearance of gingival excess and the W:L ratio, regardless of biotype. There was no association between recession and gingival excess. CONCLUSION: Subjectively, 17% of the study subjects had gingival excess. When the author (WB) made the determination that gingival excess was present, there was a significant increase in the W:L ratio for all teeth, regardless of biotype versus teeth without the presence of gingival excess. Proposed ideal W:L ratios for the mandibular anterior teeth from the second premolar to central incisor are listed in Table 11

Assisting Human Cognition in Visual Data Mining
No full textAs discussed in Part 1 of the book in chapter Form-Semantics-Function. A Framework for Designing Visualisation Models for Visual Data Mining the development of consistent visualisation techniques requires systematic approach related to the tasks of the visual data mining process. Chapter Visual discovery of network patterns of interaction between attributes presents a methodology based on viewing visual data mining as a reflection-in-action process. This chapter follows the same perspective and focuses on the subjective bias that may appear in visual data mining. The work is motivated by the fact that visual, though very attractive, means also subjective, and non-experts are often left to utilise visualisation methods (as an understandable alternative to the highly complex statistical approaches) without the ability to understand their applicability and limitations. The chapter presents two strategies addressing the subjective bias: guided cognition and validated cognition, which result in two types of visual data mining techniques: interaction with visual data representations, mediated by statistical techniques, and validation of the hypotheses coming as an output of the visual analysis through another analytics method, respectively
Visual Data Mining: An Introduction and Overview
No full textIn our everyday life we interact with various information media, which present us with facts and opinions, supported with some evidence, based, usually, on condensed information extracted from data. It is common to communicate such condensed information in a visual form - a static or animated, preferably interactive, visualisation. For example, when we watch familiar weather programs on the TV, landscapes with cloud, rain and sun icons and numbers next to them quickly allow us to build a picture about the predicted weather pattern in a region. Playing sequences of such visualisations will easily communicate the dynamics of the weather pattern, based on the large amount of data collected by many thousands of climate sensors and monitors scattered across the globe and on weather satellites. These pictures are fine when one watches the weather on Friday to plan what to do on Sunday - after all if the patterns are wrong there are always alternative ways of enjoying a holiday. Professional decision making would be a rather different scenario. It will require weather forecasts at a high level of granularity and precision, and in real-time. Such requirements translate into requirements for high volume data collection, processing, mining, modelling and communicating the models quickly to the decision makers. Further, the requirements translate into high-performance computing with integrated efficient interactive visualisation. From practical point of view, if a weather pattern can not be depicted fast enough, then it has no value. Recognising the power of the human visual perception system and pattern recognition skills adds another twist to the requirements - data manipulations need to be completed at least an order of magnitude faster than real-time in order to combine them with a variety of highly interactive visualisations, allowing easy remapping of data attributes to the features of the visual metaphor, used to present the data. In this few steps in the weather domain, we have specified some requirements towards a visual data mining system

On complexity and efficiency of mutual information estimation on static and dynamic data
No full textMutual Information (MI) is an established measure for the dependence of two variables and is often used as a generalization of correlation measures. Existing methods to estimate MI focus on static data. However, dynamic data is ubiquitous as well, and MI estimates on it are useful for stream mining and advanced monitoring tasks. In dynamic data, small changes (e.g., insertion or deletion of a value) may often invalidate the previous estimate. In this article, we study how to efficiently adjust an existing MI estimate when such a change occurs. As a first step, we focus on the well-known nearest-neighbor based estimators for static data and derive a tight lower bound for their computational complexity, which is unknown so far. We then propose two dynamic data structures that can update existing estimates asymptotically faster than any approach that computes the estimates independently, i.e., from scratch. Next, we infer a lower bound for the computational complexity of such updates, irrespective of the data structure and the algorithm, and present an algorithm that is only a logarithmic factor slower than this bound. In absolute numbers, these solutions offer fast and accurate estimates of MI on dynamic data as well.</p
Propagation of the powder stream for laser metal deposition
No full textDie vorliegende Arbeit untersucht die Einflussgrößen auf die Ausbreitung des Pulverstrahls für das Laser-Pulver-Auftragschweißen. Eine neu entwickelte Methode zur Charakterisierung des Pulverstrahls erlaubt die Berechnung des Pulverspotdurchmessers und liefert Erkenntnisse zur radialen Homogenität. Ein Modell zur Berechnung der geometrischen Ausbreitung des Pulverstrahls ermöglicht Vorhersagen über die Wahrscheinlichkeitsverteilung der Partikel. Die Ergebnisse zeigen, dass die Rauheit der Injektorinnenflächen und die daraus resultierende Streuung des Reflexionswinkels die Divergenz des Pulverstrahls bestimmen. Die Auslegung der Pulverinjektoren beeinflusst die Partikelgeschwindigkeit, die wiederum maßgeblich die Porosität der Schweißspur beeinflusst. Die Erkenntnisse tragen zur bedarfsgerechten Auslegung von Pulverdüsen bei und fördern eine höhere Prozesseffizienz sowie eine robustere Pulverzuführung
