The key question in this respect is: What are the costs of such a proposal? We argue that the welfare costs of bypassing the zero lower bound can be dealt with analytically and empirically by assuming negative interest rates on cash holdings. Adopting a money-in-the-utility-function (MIU) model, we measure the welfare loss in terms of theamount needed to compensate consumers (compensated variation), and as excess burden (deadweight loss) imposed on the economy. Firstly, we gauge the welfare effects of abolishing cash, both, for the Euro area and for Germany, and we perform several robustness checks. Secondly, we broaden the analysis by taking into account the liquidity services of assets included in the monetary aggregates M1 and M3, and we contrast the results for the year 2015 with those for the pre-crisis period 2005. Our findings suggest that the welfare losses of negative interest rates incurred by consumers and society are large, notably if implemented in a low interest rate environment. Imposing a negative interest rate of 3 percent on cash holdings and reducing the interest on all assets included in M3 creates a deadweight loss of € 62bn for euro area and of €18bn for Germany. The annual compensation required by consumers in the euro area as well as in Germany is equivalent to 2.2 percent of GDP or about €700 per capita. Thus, stepping into deep negative interest rates turns out to be a very costly economic experiment, leaving aside the potential risks and negative side effects of protracted and intensified unconventional monetary policy.

N2 - This article analyzes what drives companies to implement sustainable practices in business. A description of how sustainability affects business shall give an exemplified picture of sustainable corporate behavior. The term ‘sustainability’ is described. The approach of the three dimensions of sustainability shall serve as a basic understanding to evaluate the possibilities of an implementation of sustainability in business. The concepts of environmental management, sustainable management and Corporate Social Responsibility are described. The meaning of the driver ‘ethical responsibility’ in business is analyzed as a framework for Corporate Social Responsibility. This can be implemented in business through a code of ethics, for example. Studies and current findings confirm that Corporate Social Responsibility has become an evolving trend and is of growing importance in business today. Conclusively, the driver ‘ethical responsibility’ was found to motivate companies towards sustainable business practices.

Consequently, the need for German Small and Medium Enterprises (SMEs) to perform a digital transformation, which implies the creation of a new business model through sophisticated technologies, is gaining significance for succeeding in the digital age. While most German SMEs have already accomplished a digitization of their collaboration and communication,a profound digital transformation is still imminent for the majority. Based on the investigation of existing literature on the subject, this paper demonstrates the suitability of design thinking methods to develop strategic thrust for a digital transformation. The key potential of design thinking is rooted in its ability to creatively solve problems and reinforce skills needed to address dynamic environments. An exemplary result of using design thinking to develop strategic thrust is presented with the fictional business model GreenCube. The concept aims to assist German SMEs in performing a digital transformation by simplifying the incorporation of sophisticated digital technologies and providing opportunities for networking and thus integrating into an ecosystem. Despite their potential, design thinking activities involve several challenges including the incongruence of pre-defined specifications and designed concepts, the gap between a focus on time-reduction and a focus on experimentation, and the lack of measurability of design thinking gains. Nevertheless, the nature of businesses’internal and external environment is becoming ever more fast-paced, making the ability to manage change increasingly critical for German SMEs to establish competitive advantage.

Jahreskongress der Deutschen Vereinigung für Schulter- und Ellenbogenchirurgie (DVSE), Rosenheim 2010 N2 - Fragestellung Es soll in dieser Computersimulationsstudie untersucht werden, wie der Osteosyntheseverbund Platte mit Schrauben im Verbund mit einer im mittleren Drittel gebrochenen Clavicula durch das Bewegungsausmaß in vivo belastet ist. Was sind die grundlegenden Kräfte die auf Clavicula und Implantat wirken und welchen Einfl uss hat die Bruchform. Methodik Die Muskel- und Gelenkkräfte sowie die Belastung des Implantatverbundes wurden mit einer muskuloskelletalen Simulationssoftware (AnyBody Technology, V.4) berechnet. Hierfür wurden mit einem komplexen Model des menschlichen Körpers folgende Bewegungen analysiert: eine Flexion von 160° und Abduktion 160° mit einem Gewicht von 2 kg in der Hand. Aus CT-Patientendaten wurden zwei dreidimensionale Modelle des Clavicula-Implantat Verbundes gebildet, die sich in der Frakturform unterscheiden (Querfraktur und vertikale Fraktur). In beiden Modellen wurde eine Claviculaosteosynthese in superiorer Position mit einer 6 Loch LCP mit 2 Schrauben pro Hauptfragment verwendet. Die Materialeigenschaften wurden aus der Dichte des Materials sowie aus Literaturdaten verwendet. Die Muskel- und Gelenkkräfte aus der muskuloskelletalen Berechnung wurden auf das Finite Elemente Modell übertragen und die Spannungen und Dehnungen des Implantat-Knochenverbundes wurden berechnet. Ergebnisse Es zeigte sich, dass die simulierte in vivo Belastung stark abhängig vom Flexionswinkel ist. Das Implantat ist in der superioren Lage auf Biegung belastet, welche maximale Werte im Überschulterniveau erreicht. Die Bruchform mit anatomischer Reposition und Kontakt der Hauptfragmente zueinander führt zu einer deutlichen Entlastung des Osteosyntheseverbundes im Vergleich zu einer Bruchform mit vertikaler Fraktur. Schlussfolgerung Aus den Analysen ist eine Positionierung der Plattenosteosynthese für die im mittleren Drittel frakturierte Clavicula in anterior-superiorer Lage wünschenswert. Die anatomische Reposition entlastet den Osteosyntheseverbund und sollte möglichst erreicht werden. Die Nachbehandlung sollte ein Bewegungsausmaß für den Arm für 4 Wochen für einfache Bruchformen auf 70° Flexion und Abduktion limitieren und für komplexe Bruchformen diese Limitierung ausgedehnt werden.

These effects have been reported as adjacent joint degeneration and the development of new symptoms correlating with adjacent segment degeneration[2] and the trend has therefore gone to motion preservation devices; however, these effects have not been understood very well and have not been investigated thoroughly[3]. The aim of this study is to investigate the effect of varying the stiffness of spinal fusion devices on the adjacent vertebral levels. Disc forces, moments and facet joint forces were analyzed. METHODS The AnyBody Modeling System was used to compute the in-vivo muscle and joint reaction forces of a musculoskeletal model. The full body model used in this study consists of 188 muscle fascicles in the lumbar spine and more than 1000 individual muscle branches in total. The model has been proposed by de Zee et al.[3], validated by Rasmussen et al.[4] and by Galibarov et al.[5]. The new model[5] determines the individual motions between vertebrae based on the equilibrium between forces acting on the vertebrae from muscles and joints and the passive stiffness in disks and ligaments, figure 1a. An adult of 1.75 m and 75 kg with a spinal implant in L4L5 was modeled. This model was subjected to a flexion-extension motion using different elastic moduli to analyze and compare to a non-implanted scenario. The analyzed variables were vertebral motion, the disc reaction forces and moments, as well as facet joint forces in the treated and the adjacent levels: L2L3, L3L4, L4L5 and L5-Sacrum. RESULTS When introducing a spinal fusion device in the L4L5 joint the reaction forces and moments decreased in this joint with stiffer devices leading to lower joint loads. However, in the adjacent joints, L3L4 and L5Sacrum, an increase was observed when implanting stiffer devices. Similar trends could be found for the L2L3 joint. The loads in the facet joints showed the same trends. While introducing a spinal fusion device reduced the facet joint forces in the treated joint, the loads in the adjacent facet joints were increased according to the stiffness of the implanted device, figure 1b. DISCUSSION While the treated disc joint showed reduced motion and loads, the adjacent levels demonstrated a significant increase. In particular, the increased facet joint forces in the adjacent levels can lead to adjacent level facet pain or accelerated facet joint degeneration. Introducing a device resulted in preventing facet contact and therefore facet joint loads, even using the device with the lowest stiffness. CONCLUSION The presented model shows that clinical complications such as facet joint degeneration in adjacent levels after implantation of spinal fusion device are consistent with the change in the mechanical-stimulus distribution in the system.

Measuring these internal forces is very difficult or almost impossible; therefore, advanced models are necessary to perform musculoskeletal simulations. The objective of this investigation was to see what loads are acting in the individual foot joints from the phalanges to calcaneus and talus during different brake scenarios. The Glasgow-Maastricht AnyBody Foot Model with 26 separate segments, connected by joints, ligaments and muscles was used inside the AnyBody Modeling System to compute individual mid foot joint loads. The amount, the direction of the force and additionally also the load insertion point was varied for several simulations. Figure 1: Seated musculoskeletal body model with applied brake force and forces for the lateral, intermediate and medial cuneiform-navicular joint for two different brake forces. The simulation showed that for the different brake scenarios, different muscles will be activated in the human and therefore different loads are apply in the fore-and mid-foot, respectively. The torso of the subject was assumed to be fixed in the seat. Further studies are ongoing to simulate the seat as an elastic element that allows different H-point locations according to the different loadings in the foot from the brake pedal using a new inverse dynamics analysis method called force-dependent kinematics.

All diese Begriffe beschreiben IT, die neben den eigentlichen, regulären IT-Systemen oder -Prozessen in Unternehmen existieren und von Mitarbeiterinnen und Mitarbeitern der Fachbereiche genutzt werden. Im Fall von„Schatten-IT“ handelt es sich um IT-Systeme und -Prozesse (IT-Instanzen), die sich ohne Kenntnis der IT-Verantwortlichen etabliert haben; im Fall von„Business-managed IT“ entstehen die IT-Systeme und -Prozesse in Kenntnis der bzw. in Abstimmung mit den IT-Verantwortlichen im Unternehmen.„Fachbereichs-IT“ subsumiert Schatten-IT und Business-managed IT. Welche Ursachen führen zu solchen IT-Instanzen, welche Potenziale und Risiken haben diese IT-Instanzen und wie lassen sie sich steuern?
