Der Beitrag zeigt, welche grundlegenden Managementmethoden und -instrumente sich identifizieren lassen, um den Unterschied zwischen dauerhaft erfolgreichen und nicht erfolgreichen Unternehmen zu erklären. In diesem Konext wird ein Ansatz für einen Leistungsmanagement-Gesamtprozess entwickelt, in dem die zentralen Problemquellen bei der Einführung von Performance Management eingeordnet und erläutert werden.
Was machen dauerhaft erfolgreiche Unternehmen anders? Armin Roth identifiziert die Erfolgsfaktoren und entwickelt daraus das Konzept des ganzheitlichen Performance Managements: Es integriert die fünf Teildisziplinen Corporate Performance Management, Business Process Management, Projekt- und Mitarbeitermanagement sowie Management von Ganzheitlichkeit und Langfristigkeit in ein System. Unternehmen steigern dadurch ihre Leistungs- und Wettbewerbsfähigkeit nachhaltig. Management Cockpits sorgen dabei für eine zielorientierte Steuerung auf strategischer und operativer Ebene.
Erstmalig wird dieser integrative Ansatz in diesem Buch vorgestellt.
Services Oriented Architectures (SOA) have emerged as a useful framework for developing interoperable, large-scale systems, typically implemented using the Web Services (WS) standards. However, the maintenance and evolution of SOA systems present many challenges. SmartLife applications are intelligent user-centered systems and a special class of SOA systems that present even greater challenges for a software maintainer. Ontologies and ontological modeling can be used to support the evolution of SOA systems. This paper describes the development of a SOA evolution ontology and its use to develop an ontological model of a SOA system. The ontology is based on a standard SOA ontology. The ontological model can be used to provide semantic and visual support for software maintainers during routine maintenance tasks. We discuss a case study to illustrate this approach, as well as the strengths and limitations.
Executive education in IS is under the scrutiny of many institution for the potential to bring in financial revenues. However teaching executives can be a very challenging task because of the previous experiences, variation in their previous education, and multiplicity of motivations for pursuing a continuous education. The panel aims at sharing successful experiences and highlighting challenges of dealing with executive audiences. The panel will present the results of a large survey among executive students and identify the three most significant elements emerged from the survey: the importance of theory that is actionable, the importance of varied pedagogical tools and practices, and the importance of relevance beyond practical tools. Based on a survey that will be distributed to the audience at the beginning of the panel, the audience will be actively engaged in sharing their experiences on the three topics aiming at capitalize and sum up the collective knowledge of the room.
As "the most international company on earth", DHL Express promised to deliver packages between almost any pair of countries within a defined time-frame. To fulfill this promise, the company had introduced a set of global business and technology standards. While standardization had many advantages (improving service for multinational customers, faster response to changes in import/export regulations, sharing of best practices etc.), it created impediments to local innovation and responsiveness in DHL Express' network of 220 countries/territories. Reconciling standardization-innovation tradeoffs is a critical management issue for global companies in the digital economy.
This case describes one large, successful company's approach to the tradeoff of standardization versus innovation.
Started as a mono-line focused purely on savings, in late 2012 ING Direct Spain was becoming a full-service bank. To this end, the bank had substantially increased its product- and channel-portfolio. ING Direct Spain originally provided "simple", "good value for money" products in an "easy to deal with" way at low cost supported by a direct model. But with the growth in its product portfolio during the previous decade and the ambitious goal of becoming a full-service bank, an increase in complexity seemed inevitable. Like many businesses in the global, digital economy, ING Direct Spain found it needed to decide which complexity created value for its customers and which one not. It also learned that IT can contribute to complexity and/or help manage complexity.
This case offers a close look at challenges of growing a company by increasing product complexity to provide comprehensive yet simple services.
This article briefly describes reasons for dramatising poetry in the language classroom and then gives practical descriptions of how poetry can be taken ‘from page to stage’. It focusses on the aspects content, form and context of poems and how they can be dramatised. A special focus is on working with Shakespearean sonnets but the ideas can be transferred to other types of poetry as well.
This thesis studies concurrency control and composition of transactions in computing environments with long living transactions where local data autonomy of transactions is indispensable. This kind of computing architecture is referred to as a Disconnected System where reads are segregated -disconnected- from writes enabling local data autonomy. Disconnecting reads from writes is inspired by Bertrand Meyer's "Command Query Separation" pattern. This thesis provides a simple yet precise definition for a Disconnected System with a focus on transaction management. Concerning concurrency control, transaction management frameworks implement a'one concurrency control mechanism fits all needs strategy'. This strategy, however, does not consider specific characteristics of data access. The thesis shows the limitations of this strategy if transaction load increases, transactions are long lived, local data autonomy is required, and serializability is aimed at isolation level. For example, in optimistic mechanisms the number of aborts suddenly increases if load increases. In pessimistic mechanisms locking causes long blocking times and is prone to deadlocks. These findings are not new and a common solution used by database vendors is to reduce the isolation. This thesis proposes the usage of a novel approach. It suggests choosing the concurrency control mechanism according to the semantics of data access of a certain data item. As a result a transaction may execute under several concurrency control mechanisms. The idea is to introduce lanes similar to a motorway where each lane is dedicated to a certain class of vehicle with the same characteristics. Whereas disconnecting reads and writes sets the traffic's direction, the semantics of data access defines the lanes. This thesis introduces four concurrency control classes capturing the semantics of data access and each of them has an associated tailored concurrency control mechanism. Class O (the optimistic class) implements a first-committer-wins strategy, class R (the reconciliation class) implements a first-n-committers-win strategy, class P (the pessimistic class) implements a first-reader-wins strategy, and class E (the escrow class) implements a first-n-readers-win strategy. In contrast to solutions that adapt the concurrency control mechanism during runtime, the idea is to classify data during the design phase of the application and adapt the classification only in certain cases at runtime. The result of the thesis is a transaction management framework called O|R|P|E. A performance study based on the TPC-C benchmark shows that O|R|P|E has a better performance and a considerably higher commit rate than other solutions. Moreover, the thesis shows that in O|R|P|E aborts are due to application specific limitations, i.e., constraint violations and not due to serialization conflicts. This is a result of considering the semantics.
Ambush marketing in sports
(2014)
A sports event organizer sells exclusive marketing rights for his event to official sponsors, who, in return, acquire exclusive options to utilize the event for their own advertising purposes. Ambush marketing is the practice by companies of using their own marketing, particularly marketing communications activities, to create an impression of an association with the event to the event audience, although the companies in question have no legal or only underprivileged or non-exclusive marketing rights for this event sponsored by third parties. So, the objective of ambush marketing is to benefit from the success of sports sponsorship without having the duties of an official sponsor.
It is fine line between creative marketing communication and infringing on sponsorship rights. From the perspective of the event organizers and sports sponsors ambush marketing represents an understandable threat, while from the perspective of the ambushers it offers the opportunity to reach the target audience in an attractive environment and at affordable cost. The paper defines and structures the phenomenon of ambush marketing and analyses the impacts of ambush marketing in sports. The results of an empirical study on the effects of ambush marketing in the frame of the FIFA Soccer World cup are presented and discussed.
This booklet will give you an overview of the development of CSR from a (brief) historic point of view and will examine the underlying concepts and research. Furthermore, examples of contemporary CSR management will be explored to show how companies Interpret the issue and how they face the challenges of managing the new demands placed upon them. Business, in the end, comes down to figures and numbers which give management, shareholders and stakeholders a chance to measure a company’s success. Therefore, modern methods and approaches for measuring, rating and ranking a company’s CSR management will be presented. Finally, an attempt will be made to evaluate CSR as a tool for increasing global welfare and as a business and management strategy for companies and entrepreneurs.
Proceedings of the International Workshop on Mobile Networks for Biometric Data Analysis (mBiDA)
(2014)
Prevention and treatment of common and widesprea (chronic) diseases is a challenge in any modern Society and vitally important for health maintenance in aging societies. Capturing biometric data is a cornerstone for any analysis and Treatment strategy. Latest advances in sensor technology allow accurate data measurement in a non-intrusive way. In many cases, it is necessary to provide online monitoring and real-time data capturing to support patients´ prevention plans or to allow medical professionals to access the current status. Different communication standards are required to push sensor data and to store and analyze them on different (mobile) platforms. The objective of the workshop is to show new and innovative approaches dedicated to biometric data capture and analysis in a non-intrusive way maintaining mobility. Examples can be found in human centered ambient intelligence attributed with sensors or even in methodologies applied in automotive real-time conform mobile system design. The workshop´s main challenge is to focus on approaches promoting non-intrusiveness, reliable prediction algorithms and high user-acceptance. The workshop will provide overview presentations, Young researcher poster tracks, doctoral tracks and classical peer-review full paper tracks. Especially, would like to encourage students and young researchers to participate and to contribute to the workshop. Scientific contributions to the event are peer-reviewed by a suited program committee.
Besides the optimisation of the car, energy-efficiency and safety can also be increased by optimising the driving behaviour. Based on this fact, a driving system is in development whose goal is to educate the driver in energy-efficient and safe driving. It monitors the driver, the car and the environment and gives energy-efficiency and safety relevant recommendations. However, the driving system tries not to distract or bother the driver by giving recommendations for example during stressful driving situations or when the driver is not interested in that recommendation. Therefore, the driving system monitors the stress level of the driver as well as the reaction of the driver to a given recommendation and decides whether to give a recommendation or not. This allows to suppress recommendations when needed and, thus, to increase the road safety and the user acceptance of the driving system.
Functionally impaired people have problems with choosing and finding the right clothing. So, they need help in their daily life to wash and manage the clothing. The goal of this work is to support the user by giving recommendations to choose the right clothing, to find the clothing and how to wash the clothing. The idea behind eKlarA is to generate a gateway based system that uses sensors to identify the clothing and their state in the clothing cycle. The clothing cycle consists of (one and more) closet, laundry basket and washing machine in one or several places. The gateway uses the information about the clothing, weather and calendar to support the user in the different steps of the clothing cycle. This allows to give more freedom to the functionally impaired people in their daily life.
The impact of stress of every human being has become a serious problem. Reported impact on persons are a higher rate or health disorders like heart problems, obesity, asthma, diabetes, depressions and many others. An individual in a stressful situation has to deal with altered cognition as well as an affected decision making skill and problem solving. This could lead to a higher risk for accidents in dynamic environments such as automotive. Different papers faced the estimation as well as prediction of drivers’ stress level during driving. Another important question is not only the stress level of the driver himself, but also the influence on and of a group of other drivers in the near area. This paper proposes a system, which determines a group of drivers in a near area as clusters and it derives or computes the individual stress level. This information will be analyzed to generate a stress map, which represents a graphical view about road section with a higher stress influence. Aggregated data can be used to generate navigation routes with a lower stress influence as well as recommend driving behavior to decrease stress influenced driving as well as improve road safety.
Ein wirtschaftlicher Betrieb von KWK-Anlagen ist erreichbar, wenn Geräte mit gutem elektrischen Wirkungsgrad und geringen Anschaffungs- und Wartungskosten eingesetzt werden und der im BHKW erzeugte Strom zum größtmöglichen Anteil im Objekt verbraucht wird. Der Pufferspeicher einer KWK-Anlage sollte ausreichend groß bemessen sein (Flexibilität, Eigenstromoptimierung...). Ein größeres BHKW ist nicht automatisch unwirtschaftlicher aufgrund der geringeren Betriebszeit. Es bietet dagegen ein höheres Potenzial für eine bedarfsgerechte Stromeinspeisung in das Netz.
Die ideale Ergänzung zum Lehrbuch. Anhand von Übungen und Fallstudien lassen sich in diesem Band die zentralen Kapitel und Themen des erfolgreichen Lehrbuchs "Einführung in das Controlling" optimal wiederholen und vertiefen. Der Aufbau des Übungsbuchs orientiert sich an den wichtigsten im Lehrbuch vorgestellten Controlling-Instrumenten. Zu jedem Werkzeug bietet es Aufgaben und Fragestellungen aus der Praxis. Mithilfe der umfangreichen Fallstudie der X-presso AG, die jetzt auch in Englisch dargestellt wird, können die Studierenden sich die englische Terminologie und Fachsprache aneignen. Zusätzlich werden zusammenhängende und anspruchsvollere Aufgabenstellungen auf Prüfungsniveau angeboten. Hier können die Studierenden trainieren, das gesamte Controlling-Instrumentarium sicher zu beherrschen und anzuwenden. Zur Überprüfung gibt es ausführliche Lösungsvorschläge zu jeder Aufgabe.
Der elektrische Wirkungsgrad stellt eines der wichtigsten Bewertungskriterien für BHKW dar, da über diese Größe ausgedrückt wird, wie viel des Wertproduktes „elektrische Energie“ bezogen auf die eingesetzte oder aufzuwendende Brennstoffenergie produziert werden kann. Ein hoher elektrischer Wirkungsgrad ist somit gleichbedeutend mit hohen Erlösen aus dem Verkauf der erzeugten elektrischen Energie und damit eine grundlegende Voraussetzung für einen wirtschaftlichen Betrieb eines BHKWs. Folglich sind die Hersteller von BHKW bestrebt, den elektrischen Wirkungsgrad ihrer Geräte kontinuierlich zu verbessern und nach oben zu treiben. Dieses Bemühen zeigt sich eindrucksvoll an der Entwicklung der mechanischen Effizienz von Gasmotoren der Firma GE Jenbacher. Während mit Motoren der Baureihe 6 im Leistungsbereich 1,8 – 4,4 MWel im Jahr 1988 eine mechanische Effizienz von 34% erreichbar war, liegt dieser Wert mittlerweile bei etwa 47,5%. Diese enorme Steigerung konnte im Wesentlichen durch eine Erhöhung des mittleren effektiven Zylinderarbeitsdrucks von etwa 10 bar im Jahr 1988 auf derzeit 24 bar erzielt werden. Dabei hilft der Magerbetrieb, der gleichzeitig ein Zurückdrängen der NOx-Emissionen bewirkt, die Klopfgrenze zu höheren Drücken hin zu verschieben. Eine sichere Zündung des Gas-Luft-Gemisches wird durch die Vorkammerzündung erreicht.
Im dritten Jahr der Rezession drehte sich in Mailand alles um die italienische Lebensart und um das Erbe der großen Designer. Die spektakulären Inszenierungen fehlten weitgehend auf der Messe und in den Schauräumen rund um die Via Durini, dafür hatte man sich auf das Produkt konzentriert. Wiederbelebung der Erfolgsmodelle, Überarbeitung in Material und Farbe, Fokus auf große Namen, das waren die Botschaften in Mailand. Eine menschlich existentielle Antwort auf die Krise der letzten Jahre, aber auch Hoffnung und Aufbruchsstimmung waren zu spüren. Die Eurozone erholt sich, politischer Neubeginn und selbstbewusste Kommunikation italienischer Kultur in Stil und Design, das waren die Botschaften, die die Messe und auch die Aussteller des "Fuorisalone" vermittelten.
Increasing concerns regarding the world´s natural resources and sustainability continue to be a major issue for global development. As a result several political initiatives and strategies for green or resource-efficient growth both on national and international levels have been proposed. A core element of these initiatives is the promotion of an increase of resource or material productivity. This dissertation examines material productivity developments in the OECD and BRICS countries between 1980 and 2008. By applying the concept of convergence stemming from economic growth theory to material productivity the analysis provides insights into both aspects: material productivity developments in general as well potentials for accelerated improvements in material productivity which consequently may allow a reduction of material use globally. The results of the convergence analysis underline the importance of policy-making with regard to technology and innovation policy enabling the production of resource-efficient products and services as well as technology transfer and diffusion.
