Entwicklung und Anwendung eines Modells zur Messung von ordnungspolitischem Wandel im Gesundheitswesen: Auswirkungen der gesundheitspolitischen Reformgesetzgebung auf Perzeption und Verhalten von Chefärzten im Bundesland Bremen

Ziel dieser Modellbildung und Untersuchung ist es, der Frage nachzugehen, inwieweit die seit der zweiten Halfte der 70er Jahre andauernden Reformbemuhungen im bundesdeutschen Ge-sundheitswesen zu einer langfristigen und grundlegenden Modifikation, Umgewichtung oder gar Neudefinition gesundheitspolitischer Zielvorstellungen im stationaren Sektor gefuhrt ha-ben. Gepruft wird die Hypothese, ob als Folge der zahlreichen Kostendampfungsgesetze und insbesondere mit der Verabschiedung des Gesundheitsstrukturgesetzes im Jahre 1993 ein ord-nungspolitischer Wandel eingeleitet wurde, der sich bis heute fortsetzt. Neben dieser politik-feldbezogenen Fragestellung, wird auf einer allgemeineren Ebene das grundsatzliche Problem der Messung von langfristigem sozialpolitischen Wandel angesprochen und einer Operationa-lisierung zugefuhrt. Im Mittelpunkt der Studie stehen eine systematische Analyse der bundesdeutschen Reformge-setzgebung im Gesundheitswesen bis zum Jahre 2003 und eine qualitative Befragung von Chefarzten im Bundesland Bremen ebenfalls aus dem Jahr 2003. Ausgehend von einer Unter-suchung der Makrobene (Bundesgesetze), wird anhand einer Studie auf der Mikroebene der Implementation (Chefarzte) gezeigt, wie erfolgreich die politisch angestrebte Veranderung des Akteurshandelns auf Seiten der Leistungserbringer im stationaren Sektor bisher gewesen ist.
Control PID con diferencial electrónico para dos motores CD sin escobillas

Este documento presenta una sintonizacion PID de velocidad angular para un sistema de control con diferencial electronico para dos motores electricos sin escobillas de imanes permanentes en eje de ruedas en el vehiculo Lizard. El principal objetivo es permitir que el vehiculo pueda realizar una curva sin dificultades, puesto que carece de diferencial mecanico al poseer motor independiente en cada rueda. Se realizaron tres sintonizaciones, dos de ellas basadas en la curva de respuesta en lazo abierto en forma de s, por Ziegler-Nichols y Cohen Coon, y una tercera sintonizacion de ensayo y error. Se comparan las tres sintonizaciones para una entrada escalon, una entrada senoidal y una tipo rampa. Se observa una respuesta muy similar entre la sintonizacion Ziegler-Nichols y Cohen Coon, siendo ligeramente de mas rapida respuesta la de Cohen-Coon para una entrada escalon y senoidal, pero ligeramente mas lenta para una entrada tipo rampa. Sin embargo, ambas sintonizaciones presentaron sobreamortiguamiento elevado para una respuesta escalon. La sintonizacion por ensayo y error fue mas lenta que las demas pero presento una respuesta equilibrada, por su menor sobreamortiguamiento. La sintonizacion manual logro mejores resultados; al contar con el modelo matematico del sistema y con el software para simulacion permite optimizar los resultados de sintonizaciones como Ziegler-Nichols o Cohen-Coon.
Amergent Music: behavior and becoming in technoetic & media arts

Dérive en Mille Sons (Drifting in a Thousand Sounds) is a musical work that uses mobile media technology to artistically examine the relationship between music and the listener. Contemporary media technologies, be they at work, home or in your pocket, emphasize playback. These devices are designed to facilitate the storage and retrieval of pre-made media assets. This work leverages the processing capabilities that rest dormant within these technologies. Drawing from the writings of Guy Debord and the situationist/surrealist practice of the dérive, ‘drifting’ becomes a metaphor for instrumental performance in which the openness and emergence of interactivity is articulated through sound, as music.
Comparison of GUI testing tools for Android applications

Test automation is an intriguing area of software engineering, especially in Android development. This is since Android applications must be able to run in many different permutations of operating system versions and hardware choices. Comparison of different tools for automated UI testing of Android applications is done in this thesis. In a literature review several different tools available and their popularity is researched and the structure of the most popular tools is looked at. The two tools identified to be the most popular are Appium and Espresso. In an empirical study the two tools along with Robotium, UiAutomator and Tau are compared against each other in test execution speed, maintainability of the test code, reliability of the test tools and in general issues. An empirical study was carried out by selecting three Android applications for which an identical suite of tests was developed with each tool. The test suites were then run and the execution speed and reliability was analysed based on these results. The test code written is also analysed for maintainability by calculating the lines of code and the number of method calls needed to handle asynchrony related to UI updates. The issues faced by the test developer with the different tools are also analysed. This thesis aims to help industry users of these kinds of applications in two ways. First, it could be used as a source on what tools are over all available for UI testing of Android applications. Second, it helps potential users of these kinds of tools to choose a tool that would suit best their needs, depending on if they are most interested on test execution speed or in the easiness of developing a reliable test suite. The results of this study are the first benchmarking of these Android UI testing tools. From this thesis one can see how a few of the tools available fare up against each other in a small-scale study. Tau and Espresso share the first place in maintainability, since Tau requires the least amount of lines of code, but Espresso requires no waiting method calls to ensure synchronization of the UI. While Tau faced least general issues during the test suite development, Espresso is clearly the fastest of the tools and it attains highest level of reliability, so it seems to be the best choice of the tools.
List of Twin Clusters: A Data Structure for Similarity Joins in Metric Spaces

The metric space model abstracts many proximity or similarity problems, where the most frequently considered primitives are range and k-nearest neighbor search, leaving out the similarity join, an extremely important primitive. In fact, despite the great attention that this primitive has received in traditional and even multidimensional databases, little has been done for general metric databases. We consider a particular type of similarity join: Given two sets of objects and a distance threshold r, find all the object pairs (one from each set) at distance at most r. For this sake, we devise a new metric index, coined List of Twin Clusters, which indexes both sets jointly (instead of the natural approach of indexing one or both sets independently). Our results show significant speedups over the basic quadratic-time naive alternative. Furthermore, we show that our technique can be easily extended to other similarity join variants, e.g., finding the k-closest pairs.
An Evaluating Method for Dexterity of Robot Manipulators Considering Deviation of Direction of Motion

Dexterity is an important issue for design, installation planning, trajectory planning, etc. of manipulators. Many evaluating methods have been proposed such as Yoshikawa's manipulability. They have, however, some problems, one of which is that they cannot consider characteristics of manipulator motion. It has been impossible to evaluate how efficient a manipulator mechanism is from a viewpoint of characteristics of a required task. A manipulator should be evaluated to be dexterous when it can efficiently perform its required task even if it cannot accomplish other kind of tasks very well. In this paper, a new dexterity measure stochastic manipulability measure is presented. It can evaluate kinematic dexterity considering deviation of direction of required manipulator motion, which is one of the characteristics of a task. Stochastic manipulability is based on expected value of mean of necessary joint velocity under a stochastic interpretation of required motion. The deviation is specified using a probability density function. Applications to 2-, 3and 6-DOF manipulators revealed the following: 1. stochastic manipulability can evaluate dexterity considering deviation of motion, 2. it can be used for comparison of manipulators with different DOFs, 3. it is important to consider the deviation of motion in evaluation, 4. singular points can substantially lose their singularity, and 5. optimal trajectory of redundant manipulators can be obtained using maps in null space of Jacobian matrix.
Comparing electronic vs print book preferences between students in the social sciences, the arts and STEM

Purpose – The purpose of this study was to determine if there were any distinct differences in e-book usage habits among students in the social sciences, technical fields and the arts. Design/methodology/approach – To complete this study, students from three different disciplinary areas were surveyed. The same nine questions were posed to each student group, with slight modifications to some questions based on the discipline. Findings – The results of this study show that students in each discipline have a preference for convenience and accessibility, whether material is print or electronic. Some more unique characteristics between disciplines include the percentage of students using books and frequency of e-book usage. Originality/value – This study is unique in that it compares the preferences and habits of three specific groups of students from unrelated disciplines. It will be useful for librarians who manage collections for various disciplines and want a better understanding of what should be conside.
Carpentier's Reconstructive Valve Surgery

This long-awaited book is an autobiographical account by Professor Alain Carpentier of his work on the surgical management of heart valve disease and in particular that of the mitral valve. Although it includes reference to surgery on the tricuspid and aortic valves its major attraction will be the complete expose of the author's techniques and rationale behind his ‘school’ of mitral valve reconstruction. The growing interest in reconstructive mitral valve surgery is well served by the production of this book. It describes the principal author's pioneering surgical stratagem and practical procedures derived during 40 years' experience. The target readership is undoubtedly all of those cardiac surgeons interested in the reconstruction of dysfunctional heart valves. Question and answer sessions at the end of each chapter help to draw out detail that otherwise personal explanations may conceal. The other strength of this book is the clarity of the artwork. The inclusion of well-executed drawings (mainly watercolour washes supervised by the author and based on his preliminary sketches), with photographs, echocardiographic images and tables leave the reader in no doubt of the surgical steps that are intended. The didactic manner of teaching used by Professor Carpentier, while clearly delivering the intended message, also shows a degree of reluctance to acknowledge some other points of view. For example, in discussing the presence or absence of the mitral annulus, the author insists on its reality while reporting the anatomist's demonstrations of its non-existence. It is nonetheless well referenced, allowing independent verification of the data that are included within the text. The book does achieve the author's stated aim that: ‘This book is not a “compendium” of all existing techniques of valve repair. It describes a comprehensive system of valve analysis and reconstructive techniques validated in more than 10,000 patients in (my) institution’. It will become an account treasured by all of those cardiac surgeons who owe a debt of gratitude to this pioneering surgeon.
Experts et expertise judiciaire. France, XIXe et XXe siècles

Negligee par les historiens, boudee par les juristes, delaisse par les sociologues, et finalement ignoree par la recherche, l'histoire des experts et de l'expertise judiciaire s'avere essentielle pour comprendre a la fois le fonctionnement de la justice et celui des societes contemporaines. Aujourd'hui, tandis que l'actualite apporte son lot quotidien d'episodes tragiques (explosions, accidents du travail, catastrophes aeriennes, tragedies maritimes, tremblement d'un animal de ferme ou de boucherie.) la demande d'expertise ne cesse de croitre. Pour autant les etudes historiques n'abordent pas la 'question expertale'. L'ouvrage entend ainsi combler une lacune pour les XIXe et XXe siecles. Il a pour visee de traiter de l'expertise judiciaire qui constitue la matrice et le modele de toutes les procedures d'expertise. A la fin du XIXe siecle l'expression 'justice scientifique' fait irruption dans de doctes traites ouvrant ainsi un debat, loin d'etre referme, sur la place qu'il convient d'accorder a la solution proposee par les experts. A la veille du second conflit mondial, la 'puissance' des experts montre qu'ils sont devenus une des pieces maitresses de la justice. Leur pouvoir d'investigation apparait presque illimite. Toutes les caracteristiques de leurs specialisations et de leurs missions sont en place et pourtant ils sont les meconnus de l'histoire judiciaire. Ce livre entend saisir les transformations de l'instruction et du proces, comprendre la nouveaute qu'a represente l'expertise judiciaire, cerner les grandes evolutions, analyser les crises , scruter les rapports du juge et des experts, suivre enfin l'expansion des expertises.
Chipmusic e o resgate da estética dos anos 1980 e 1990

Este artigo tem como objetivo descrever a cena chipmusic e como a utilizacao de equipamentos das decadas de 1980 e 1990, pelos musicos, tem influenciado tambem na estetica dos produtos visuais da cena. Partindo do pressuposto de que as maquinas tem memoria, construimos a ideia de uma “estetica zumbi”, resgatada pelos integrantes da chipmusic nos mais diversos produtos da cena, como capas de albuns, sites e imagens utilizadas nas apresentacoes ao vivo.
Use of Turnitin and a Class Tutorial to Improve Referencing and Citation Skills in Engineering Students

Accidental and deliberate plagiarism is an issue in higher education internationally, particularly in engineering and science subjects, and is becoming easier to undertake and more time consuming to detect due to the increase in availability of digital sources via the internet. This paper describes a phased approach to educating students about correct citation and referencing practice, through the use of a workshop with examples of good practice and the use of Turnitin text matching software as a formative tool to assist students to develop their writing skills. Students reported that Turnitin was not as effective as a formative tool as the workshop, and perceived the workshop to be most effective when delivered by the course tutor. Interestingly the most significant resource reported by students were examples of good citation and referencing provided by the course tutor in lecture notes.
A new approach for load flow analysis of integrated AC–DC power systems using sequential modified Gauss–Seidel methods

SUMMARY The paper describes a new approach for the load flow calculations of integrated AC–DC system. A simple and reliable method for sequential modified Gauss and Gauss–Seidel power flow for AC–DC system is developed. This approach is based on applying nodal injection theory at all buses. The DC system is treated by the current injected to the buses where it is connected and its effect is reflected at internal buses by additional power injection. Iterations between AC and DC power flow algorithms are made to match boundary conditions between the two systems. In this approach, the active and reactive power and the AC voltages at the converter buses are considered as the interface between the AC and DC equations in each iteration step. The combined AC–DC equations are solved separately using sequential modified Gauss and Gauss–Seidel methods. The developed algorithm to solve the AC–DC power flow has been tested on the IEEE 9-bus test system. Copyright © 2011 John Wiley & Sons, Ltd.

Efficient foreground detection for real-time surveillance applications

The problem of foreground detection in real-time video surveillance applications is addressed. Proposes is a framework, which is computationally cheap and has low memory requirements. It combines two simple processing blocks, both of which are essentially background subtraction algorithms. The main novelty of the approach is a combination of an autoregressive moving average filter with two background models having different adaptation speeds. The first model, having a lower adaptation speed, models long-term background and detects foreground objects by finding areas in the current frame which significantly differ from the proposed background model. The second model, with a higher adaptation speed, models the short-term background and is responsible for finding regions in the scene with a high foreground object activity. The final foreground detection is built by combining the outputs from these building blocks. The foreground obtained by the long-term modelling block is verified by the output of the short-term modelling block, i.e. only the objects exhibiting significant motion are detected as real foreground objects. The proposed method results in a very good foreground detection performance at a low computational cost.
REDUCED WAITING TIMES – PHYSIOTHERAPY SHOULDER ASSESSMENT CLINIC

A pilot study of a physiotherapy led shoulder clinic was initiated in January 1999 as a direct response to increasing orthopaedic consultant out-patient clinic waiting times. The orthopaedic consultant reviews letters from GP’s to the orthopaedic clinic. Patients with benign musculoskeletal shoulder problems are referred to Shoulder Assessment Clinic (SHAC). The physiotherapist completes a subjective and objective assessment and a shoulder score is recorded using Constant and Murley Shoulder (Constant and Murley 1985). The scoring system has a maximum of 100 points indicating perfect, pain-free movement and function. The Constant and Murley Shoulder score remains most widely used and validated scoring system in Europe for the shoulder. A total of 130 patients were referred to SHAC between January 1999 and December 1999. Sixty-six patients were treated and discharged by physiotherapy alone with an average increase in shoulder score of 40 points. Twenty-seven had surgery, 19 had steroid injection. Overall waiting time to be seen in SHAC was 58 days. Since this initial pilot, 320 patients have been assessed and treated in the SHAC. Our experience of physio-led shoulder clinic shows patients can be assessed and treated with a far shortened waiting time, and the improved shoulder scores suggest effective treatment. This allows more patients of an appropriate type to be seen in the outpatient orthopaedic clinic.
Réplica: ¿Saben los estudiantes de Ecología quién fue G.E. Hutchinson?

Viajar es interesante y necesario para los ecólogos. Visitar otros ecosistemas nos permite poner en contexto aquellos sistemas y procesos en los que trabajamos y darnos cuenta de que no todo ocurre con igual frecuencia o intensidad en todas partes. Nos ayuda a entender que las interacciones ecológicas son más variadas y complejas de lo que podemos deducir del pequeño espacio en el cuál la mayoría de nosotros desarrollamos normalmente nuestras investigaciones.
