Der Beitrag untersucht die Wirkung verschiedener Einflussfaktoren auf die Perzeption von Unordnung. Einer Einführung in die theoretische Diskussion rund um die Wirkung von Unordnung auf das urbane Sozialgefüge folgen verschiedene multivariate Berechnungen (N = 2003). Hierzu wird ein additiver Index aus dem Produkt von subjektiver Schwere und perzipierter Häufigkeit verschiedener Erscheinungsformen physischer und sozialer Unordnung gebildet. Die Regressionsergebnisse zeigen, dass die soziale Struktur urbaner Nachbarschaften, der bedingte Erwartungswert für die kollektive Wirksamkeit informeller Sozialkontrolle sowie solche Prädiktoren, welche die Bedeutung des unmittelbaren sozialen Nahraumes für Prozesse kognitiver Dissonanzbewältigung betonen (Viktimisierung, Wohnverhältnis, Kriminalitätseinstellungen), erklären, wann ein Akteur eine Situation als unsicher definiert und infolgedessen Unordnung als Anzeichen von Gefahr interpretiert. Der dem Explanans zugrundeliegende soziale Mechanismus beruht auf der Theorie der Frame-Selektion nach Esser (1991).

An introduction to the theoretical discussion about the impact of disorder on the urban social structure is followed by different multivariate regressions (N = 2003). The perception of different images of physical and social disorder is measured in terms of the sentimental value of disorder and the perceived frequency of disorder. An additive index using product terms of the sentimental value and the perceived frequency for each image is constructed. The results of the regressions indicate that social structure of urban neighborhoods, collective efficacy, and such predictors which aim at the significance of social proximity (victimization, housing situation, personal crime settings) for processes of cognitive dissonance coping explain when an actor defines a situation as not-secure and subsequently interprets disorder as a symbol of danger. Esser’s (1991) theory of frame-selection functions as the social mechanism of the explanans. The hypotheses are tested on survey data provided by the city of Leipzig (2011).:1 Einleitung 2 Theorie 2.1 Hunter (1978) 2.2 Wilson und Kelling (1982) 2.3 Exkurs 2.4 Lewis und Salem (1986) 2.5 Skogan (1990) 2.6 Das Konzept der collective efficacy 3 Hypothesen 3.1 Der Grundzusammenhang des theoretischen Modells 3.2 Die Brückenhypothesen des Modells 3.2.1 Direkte und indirekte Viktimisierung 3.2.2 Kriminalitätsfurcht 3.2.3 Medienrezeption 3.2.4 Kontrollvariablen 4 Daten, Operationalisierungen, Methoden 4.1 Daten 4.2 Operationalisierungen 4.2.1 Abhängige Variable(n) 4.2.2 Unabhängige Variablen 4.3 Methoden 5 Auswertung 5.1 Bivariate Ergebnisse 5.2 Multivariate Ergebnisse 6 Fazit und abschließende Bemerkungen 7 Anhang 8 Literaturverzeichnis

Dans certains contextes, les méthodes classiques utilisées pour le calcul de champs rayonnés ou diffractés en présence d'obstacles de grande taille par rapport à la longueur d'onde, comme l'Optique Physique ou les méthodes de rayons, ne sont pas valides ou deviennent très lourdes en temps de calcul. La théorie des frames de Gabor fournit un cadre rigoureux permettant de décomposer une distribution de sources électromagnétiques, définie dans une ouverture équivalente plane, en une somme plus ou moins redondante de fenêtres gaussiennes. Cette décomposition peut servir de base à des algorithme de lancer de faisceaux gaussiens.Jusqu'à présent cette théorie était limitée à des décompositions dans un plan (rayonnement dans un demi-espace). L'objet de cette thèse est d'utiliser cette théorie pour décomposer des champs rayonnés ou diffractés dans toutes les directions de l'espace. Ce travail de thèse commence par une étude approfondie de l'influence des paramètres utilisés pour le calcul des coefficients de frame. La mise en oeuvre numérique permet de tester l'efficacité de techniques de troncation et de compression en termes de compromis précision/temps de calcul. Le coeur de la thèse consiste en une méthode originale de partitionnement spectral, utilisant des fonctions de partition de l'unité, qui permet d'utiliser le lancer de faisceaux gaussiens à partir de frames définis dans six plans, pour un rayonnement dans tout l'espace tridimensionnel. La formulation de la méthode est présentée. Elle est appliquée à la décomposition en faisceaux gaussiens du champ rayonné par des antennes théoriques omnidirectionnelles (réseau de dipôles et dipôle demi-onde). Une antenne réaliste sert enfin de cas test pour la mise en œuvre de la décomposition à partir de données expérimentales discrètes / In some contexts, conventional methods used for large problems involving radiated or diffracted field computations in the presence of obstacles, such as Physical Optics and ray based methods, become really inaccurate or prohibitively time-consuming. Gabor frame theory provides a rigorous framework for the initial decomposition of equivalent source distributions into a redundant set of Gaussian windows. Frame decomposition has been introduced as a first discretization step into Gaussian Beam Shooting (GBS) algorithms. Until now, frame decomposition has essentially been restricted to planar source distributions, radiating into one half space. The main goal of this thesis is to extend the application range of this theory to radiated or diffracted field decomposition into Gaussian beams propagating into the whole space. The thesis begins with a thorough study of influence of the parameters used for frame coefficient calculation. Numerical implementation is used to test the efficiency of truncation and compression techniques in terms of accuracy / computation time balance optimization. The core of the thesis consists of an original spectral domain partitioning method involving partition of unity functions, which allows to use Gaussian beam shooting from frames defined in six planes, for radiation into the whole three-dimensional space. The formulation of the method is presented and applied to the decomposition of fields radiated by theoretical omnidirectional antennas (dipole array and half-wave dipole) into Gaussian beams. A realistic antenna is used as a test case for the implementation of decompositions based on experimental discrete initial data

A major concern for most leadership development teams is aligning training and development goals to desired outcomes, especially when looking at overall costs to plan and implement effective training programs. Leadership training in healthcare is increasing due to the complexity of duties and the need to deal with conflicting situations on a regular basis. This study explored whether goals and assessment instruments identified and applied by program development managers were adequate to reflect a multi-frame perspective, and whether participant feedback articulates benefits encompassing multiple frames. Four main questions were used in the study: “What potential benefits do leadership development staff who select, design, and evaluate training articulate; and do they capture a multi-frame perspective? How do the goals of the program development managers align with the assessment of evaluation instruments, and do the assessments reflect a multi-frame perspective? How does the perception of training benefits align with leadership development goals and multi-frame perspective? What effect does training in competencies such as, problem-solving, conflict management, and effective communication have on leaders in healthcare?” To highlight a potential link between behavior, change and organizations; Social Cognitive, Human Needs, and Systems Theories were utilized. A mixed-method design applying Interpretative Phenomenological Analysis and Descriptive Statistics was used. Results of the study indicate that the goals identified by leadership development do align with trainees outcomes in terms of: serving as a support mechanism to ensure effective team-building; facilitating growth towards promotion through education and effective feedback; and enhancing leadership core competencies such as, emotional intelligence, conflict management and communication skills.
