Agile Werte leben
Mit Improvisationstheater zu mehr Selbstorganisation und ZusammenarbeitWas hat Improvisationstheater mit Agilität zu tun? Eine ganze Menge! Denn Agilität ist mehr als Kanban-Kärtchen durch die Gegend schieben, Planning Poker spielen und einen Scrum-Sprint zu planen.Agile Werte und die aus ihnen abgeleiteten Prinzipien in der täglichen Arbeit von Teams oder gar ganzen Organisationen zu verankern, ist keine einfache Aufgabe. Denn oft scheinen diese zu abstrakt und wenig alltagsnah. Und gerade bei verteilten Teams ist es schwierig diese umzusetzen.Robert Wiechmann und Laura Paradiek zeigen Übungen und Techniken aus dem Improvisationstheater, die helfen diese Werte greifbar und erfahrbar zu machen. Hollywoodreife Schauspielkünste sind dafür nicht nötig. Denn im Impro geht es darum, gemeinsam Ideen zu entwickeln, aufeinander zu achten, zusammenzuarbeiten, miteinander zu kommunizieren und aufeinander zu zählen. Auch wenn man sich nur per Kamera sieht.Die Spanne reicht von ganz einfachen bis zu komplizierteren Übungen, damit sich jeder zutraut, mitzumachen. Aha-Momente und ein besseres Verständnis der agilen Werte sind vorprogrammiert.Dieses Buch ...führt in agile Werte ein und erklärt, warum diese so wichtig sind.zeigt, was Improtheater eigentlich ist und warum es agilen Teams und Organisationen helfen kann.gibt übersichtlich und strukturiert Improübungen an die Hand.Über den Autor:Diplom-Kaufmann Robert Wiechmann unterstützt mit Herzblut Organisationen bei ihrer agilen Transition. Neben dem Aufbau und der Beratung von Scrum- und Kanban-Teams in der Softwareentwicklung lässt er auch alle weiteren Unternehmensbereiche nicht aus dem Auge. Er hat Freude daran, Teams jeglicher Fasson zu einer Einheit zusammenzuschweißen und sich dabei ständig weiterzuentwickeln. Die Basis seiner Arbeit baut auf Respekt, Vertrauen sowie Wertschätzung auf. Wichtig ist ihm das Zusammenspiel von Zielorientierung, Klarheit, Einfachheit, Selbstverantwortung, Kreativität und Spaß. Sein Mut, offen auch unbequeme Dinge anzusprechen, lässt die Arbeit mit ihm praxisorientiert und auf Augenhöhe sein. Seine Arbeit als Agiler Coach ist von Kreativität geprägt und scheut auch nicht die Beschreitung neuer Wege.Laura Paradiek ist Kommunikationsfachfrau, Schauspielerin und ausgebildete Business-Trainerin. Nach ihrem Studium der Gesellschafts- und Wirtschaftskommunikation in Berlin führte sie ihr Weg in viele kleine und große Unternehmen. Ob in der Kommunikationsplanung, Veranstaltungsorganisation oder dem Management von Webprojekten – agile Projektmanagementmethoden sind ihr A und O. Neben Scrum und Kanban setzt sie auf Methoden aus dem Improvisationstheater und der Visualisierung. Seit sie 12 Jahre alt ist, steht sie auf der Bühne, u. a. mit der Theater Jugend Hamburg, dem Maxim Gorki Theater in Berlin oder der Hamburger Improvisationstheatergruppe SchillerKiller.
Mit grünen Informationssystemen ineffektive Datentransfers vermeiden. Ein Ansatz zur Nachhaltigkeit in Unternehmen
Um heute wettbewerbsfähig zu bleiben, müssen Unternehmen ihren Mitarbeitern eine Vielzahl von Informationen zur Verfügung stellen. Häufig werden dabei auch viele irrelevante oder veraltete Daten übermittelt, sodass die Mitarbeiter die Suche nach den wichtigen Informationen als ineffektiv empfinden. Gleichzeitig kostet jeder Datentransfer Energie.Welche ökologischen Auswirkungen haben der Abruf und die Übertragung von unnützen Daten? Wie kann eine benutzerzentrierte Ausrichtung der Informationsbereitstellung Energie einsparen? Inwiefern unterscheidet sich ein „Green Knowledge Managementsystem“ von einem „traditionellen“ Wissensmanagementsystem?Nathalie Serban stellt ein „grünes“ Informationssystem vor. Hiermit können Unternehmen mehr Transparenz über Ansprechpartner, Zuständigkeiten, Informationen und Projekte im Aufgabenbereich des jeweiligen Mitarbeiters schaffen und somit irrelevante Datentransfers vermeiden. Ihr Buch richtet sich an Manager, Führungskräfte und IT-Beauftragte.Aus dem Inhalt:- Wissensmanagement;- Umwelt;- CO2;- Ökologie;- E-Mail;- Wettbewerb

Topics in Multiphase Transport Phenomena
Chapter 1 A Fluid-Porous Solid Reaction Model With Structural Changes, supplies details on modeling reactions with porous catalysts. The unique feature of this chapter is the pore closing, pore opening condition. This analysis is particularly useful for improving the design of storage batteries. Until the publication of “A Model for Discharge of Storage Batteries” by Dimitri Gidaspow and Bernard S. Baker, Journal of the Electrochemical Society,120, 1005-1010 (1973) the discharge of batteries was described by a purely empirical equation as a function of time. Chapter 2 Kinetics of the Reaction of CO2 With Solid K2CO3, complements U.S. patent No. 3,865,924 (February 11,1975) by Dimitri Gidaspow and Michael Onischak, on rates of carbon dioxide (CO2) capture. These rates of reaction were measured in a parallel plate channel at several laminar flow velocities. An integral equation flow analysis was used to obtain diffusion independent rates of reactions. Chapter 3 Silicon Deposition Reactor Using High Voltage Heating, describes an internally heated fluidized bed with no size limitations and with no bubble formation and its simulation. Chapter 4 Alternative Methods of Deriving Multiphase Field Equations, constitutes a literature review of approaches that have been used and/or proposed in the literature to derive multiphase flow equations which could form the basis of the theory and computation of dense suspensions of particulates such as coal-water slurries or blood flow.

Protektion 4.0: Das Digitalisierungsdilemma
Das Buch beschreibt Datenschutz erstmals als Offenheit (Transparenz) statt Datensparsamkeit. Der Autor beschreibt als Voraussetzung dazu einen Besitztitel auf Daten. Die Umsetzung erfolgt über Big Data, deren Techniken so ausgelegt sind, dass Daten zur „handelbaren“ Ware werden können, indem dokumentierbar wird, wie von wem wozu Daten verwendet worden sind. Transparente Verwendung auch in Hinsicht auf den Nutzen oder die Notwendigkeit statt Verbergen wird als neues Privatheitsmodell vorgeschlagen. Die Synchronisation der Entwicklung von Technik und Gesellschaft steht dabei im Vordergrund. Zahlreiche Fallstudien erhöhen den praktischen Nutzen des Buches.PROFESSOR GÜNTER MÜLLER hat als Direktor der IBM Forschung Europa mit der Entwicklung zu Datennetzen die Digitalisierung gefördert.Sicherheit und Privatheit als Kontrollelement der Innovation war sein Thema an der Universität Freiburg und am von ihm gegründeten Institut für Informatik und Gesellschaft. Er konnte dazu internationale Netzwerke etablieren; insbesondere das Daimler-Benz-Kolleg, den Schwerpunkt „Sicherheit“ in der DFG, die Mitgliedschaft im Feldafinger Kreis, die bis heute anhaltende Kooperationen mit den Universitäten Wien, Tokio und Harvard und nicht zuletzt die richtungsweisende ACTECH-Studie zu Privatheit und die Zusammenarbeit mit Fraunhofer Darmstadt. Eine algorithmische Ordnung der Plattformen gefährdet das Gemeinwohl und reduziert die Potentiale der Informationstechnik zur Lösung der wichtigen Probleme der Menschheit. Für sein Wirken wurde ihm die Ehrendoktorwürde der TU Darmstadt und das Ehrenkreuz der Republik Österreich verliehen.

Refactoring Legacy T-SQL for Improved Performance
Breathe new life into older applications by refactoring T-SQL queries and code using modern techniques. This book shows you how to significantly improve the performance of older applications by finding common anti-patterns in T-SQL code, then rewriting those anti-patterns using new functionality that is supported in current versions of SQL Server, including SQL Server 2019. The focus moves through the different types of database objects and the code used to create them, discussing the limitations and anti-patterns commonly found for each object type in your database.Legacy code isn’t just found in queries and external applications. It’s also found in the definitions of underlying database objects such as views and tables. This book helps you quickly find problematic code throughout the database and points out where and how modern solutions can replace older code, thereby making your legacy applications run faster and extending their lifetimes. Author Lisa Bohm explains the logic behind each anti-pattern, helping you understand why each pattern is a problem and showing how it can be avoided. Good coding habits are discussed, including guidance on topics such as readability and maintainability.WHAT YOU WILL LEARN* Find specific areas in code to target for performance gains* Identify pain points quickly and understand why they are problematic* Rewrite legacy T-SQL to reduce or eliminate hidden performance issues* Write modern code with an awareness of readability and maintainability* Recognize and correlate T-SQL anti-patterns with techniques for better solutions* Make a positive impact on application user experience in your organizationWHO THIS BOOK IS FORDatabase administrators or developers who maintain older code, those frustrated with complaints about slow code when there is so much of it to fix, and those who want a head start in making a positive impact on application user experience in their organizationLISA BOHM leads a team of database administrators for a software development company. Her history with legacy database code began early in her career with a summer project to rewrite the chemical inventory database for the research division of a local VA hospital. From there, she went on to building front-end web applications. When the web calls timed out, Lisa dug in to learn what databases can do. She has since transitioned into database administration, inheriting and improving legacy applications along the way. Her personal focus remains on solid database architecture and writing well-performing T-SQL.PART I. EVERYTHING IS SLOW1. T-SQL Triage2. DocumentationPART II. DATABASE STRUCTURE3. Database Tables4.

Formative Assessment and Feedback Tool
In this book, Kevin Duss tackles the well-known problem in the teaching structure of today’s universities that despite the immense potential of formative feedback towards students is not or only insufficiently applied. The author uses existing research and modern technologies to develop a web-based feedback application that enhances both objective and perceived student performance. This work makes a first step towards a design theory for formative feedback applications and gives guidance for their successful implementation.

Maschinen der Kommunikation
EIN BUCH ÜBER MENSCHEN, MASCHINEN UND IHRE VERBINDUNGENDigitale Endgeräte sind längst zu einem festen Bestandteil unserer Gesellschaft geworden. Aber wie wirkt sich der technische Fortschritt auf unser tägliches Zusammenleben aus? Antworten auf diese Frage liefert das neue Buch über die wechselseitigen Beziehungen zwischen Mensch und Maschine.DIGITALISIERUNG ALS KULTURELLE REVOLUTIONDass neue Technologien industrielle und wirtschaftliche Prozesse verändern, lässt sich leicht anhand von Portalen wie eBay oder Amazon belegen. Das Internet setzt aber auch weniger sichtbare Veränderungen in Gang. So nehmen technische Innovationen Einfluss darauf, wie wir Menschen Informationen vermitteln, aufnehmen und verarbeiten. Zu solchen Innovationen zählen:* Chatbots* Humanoide Roboter* Digitale AgentenDer Wandel kultureller Praktiken bedeutet jedoch nicht, dass menschliches Miteinander auf Kosten eines automatisierten Überwachungsapparates verloren geht. Die Herausgeber Klimczak, Petersen und Schilling rufen in ihrem Buch zu einem fachübergreifenden Austausch über die Kommunikationsweisen zwischen Mensch und Maschine auf.POSTHUMANISMUS AUS INTERDISZIPLINÄRER SICHTDie Herausgeber dieses Buchs über Mensch, Maschine und Gesellschaft arbeiten an der Technischen Universität in Brandenburg in den Bereichen Medienforschung und Kognitive Systeme. Ihre Kollaboration basiert auf einer engen Vernetzung von kulturwissenschaftlichen und informationstechnologischen Disziplinen. Konkret bedeutet das:* Geisteswissenschaftler müssen die maschinellen Grundlagen ihrer digitalen Untersuchungsobjekte verstehen.* Technische Entwickler müssen verstehen, wie ihre Erfindungen kulturelle Verhältnisse verändern. Auch wenn die Herausgeber für ihr Buch über die komplexen Zusammenhänge zwischen Mensch und Maschine eine Vielzahl an Perspektiven heranziehen, werden immer wieder Überschneidungen deutlich. Deshalb richtet sich dieses Werk an Forscher und Praktiker aus verschiedensten Fachgebieten, darunter:* Informatik* Nachrichtentechnik* Kulturwissenschaft* Soziologie* PhilosophieNur, wenn all diese Disziplinen an einem Strang ziehen, kann unsere Gesellschaft die Herausforderungen meistern, die Neue Medien und Künstliche Intelligenz mit sich bringen.PETER KLIMCZAK, Dr. phil. et Dr. rer. nat. habil., ist Privatdozent an der MINT-Fakultät der Brandenburgischen Technischen Universität.CHRISTER PETERSEN, Dr. phil., ist Professor für Angewandte Medienwissenschaften an der Brandenburgischen Technischen Universität.SAMUEL SCHILLING, M.A., ist Projektmitarbeiter am Forschungscluster Kognitive Systeme der Brandenburgischen Technischen Universität.Metadaten.- Wissen und Suchmaschinen.- Personalisierung.- Mensch, Maschine, Gesellschaft.- Maschinenlernen.- Normativität.
