Infusing with ERP Systems: A Longitudinal Investigation of the Impact of Control and Empowerment

Organizations have made significant investments in ERP systems with the strategic expectation that employees will utilize this technology to enhance organizational performance. However, research indicates that ERP systems are under-utilized. In order to entangle the challenge of under-utilization, this paper addresses the impact of control and empowerment on infusion – the deep and comprehensive usage of an information system. We apply a longitudinal design with two measurements to research whether the level of infusion of ERP users changes over time, and if so to what extent. Moreover we hypothesize that ‘soft’ characteristics like the organizational position, organization commitment and trust influence the relation between control, empowerment and the level of infusion of the ERP user. A survey was conducted in a large public organization which has been using an ERP system for several years. A sample of 178 matched pairs (For T1 and T2) of ERP system users and their supervisors has been collected. In this research in progress we present the theoretical mechanisms and methodological framework we employed for the data collection

Minimal information for studies of extracellular vesicles 2018 (MISEV2018):a position statement of the International Society for Extracellular Vesicles and update of the MISEV2014 guidelines

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles (“MISEV”) guidelines for the field in 2014. We now update these “MISEV2014” guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points

Information System Infusion: The Role of Control and Empowerment

Organizations have made significant investments in ERP systems, expecting that employees utilize the technology to enhance organizational performance. However, research indicates that many systems are under-utilized. This paper addresses the impact of control and empowerment on infusion – the deep and comprehensive usage of an information system. Moreover, it also tests whether infusion leads to higher levels of ERP success. A survey was conducted in a large public organization which has been using an ERP system for several years. Results indicate that empowerment is positively related with infusion, while an inverted u-relationship has been found for control. The critical link between infusion and ERP system success was found as well, meaning that the more users utilize the system to its fullest extent, the more likely the organization can attain its promised benefits. Finally, traditional predictors of the acceptance and routinization phases were found to be inappropriate when examining infusion

Post-implementation ERP usage:A longitudinal study of the impact of control and empowerment

Organizations have invested in Enterprise Resource Planning (ERP) systems expecting to obtain benefits of the system and realize a healthy return on investment. Nonetheless, research indicates that employees rarely use ERP to its full potential. To tackle the challenge of underutilization, this article studies the longitudinal impact of control and empowerment on usage behaviors at the individual level. Results indicate that users engage in different but coexisting usage behaviors: routinization and infusion

Kennismanagement-capabilities van defensie: Leren van het programma SPEER

Net als veel andere bedrijven heeft Defensie besloten om een Enterprise Resource Planning (ERP) systeem te implementeren. Het programma SPEER was verantwoordelijk voor de implementatie en belast met de transformatie van de bedrijfsvoering en sanering van de informatievoorziening. Nu SPEER is beeindigd, is het goed om te inventariseren wat de ervaringen van het programma betekenen voor de kennismanagement- capabilities van Defensie. Dit is het vermogen om kennis vanuit diverse bronnen, zoals databases, documenten en mensen, te ontsluiten en te delen zodat Defensie de primaire taken effectief uit kan voeren. We destilleren in dit artikel drie tactieken op het gebied van kennismanagement, die kunnen dienen als lessen voor toekomstige implementatietrajecten. Verder concluderen we dat om lopende uitdagingen te overwinnen een vierde tactiek nodig is, gebaseerd op co-creatie en topdown-gestuurd kennismanagement. Daarnaast pleiten we voor een rol voor de Chief Knowledge Officer, die barrières die de vrije stroom van kennis door de organisatie verhinderen zou moeten kunnen overwinnen

Aerodynamic drag in cycling pelotons: New insights by CFD simulation and wind tunnel testing

A cycling peloton is the main group of cyclists riding closely together to reduce aerodynamic drag and energy expenditure. Previous studies on small groups of in-line drafting cyclists showed reductions down to 70 to 50% the drag of an isolated rider at same speed and these values have also been used for pelotons. However, inside a tightly packed peloton with multiple rows of riders providing shelter, larger drag reductions can be expected. This paper systematically investigates the drag reductions in two pelotons of 121 cyclists. High-resolution CFD sim- ulations are performed with the RANS equations and the Transition SST-k-ω model. The cyclist wall-adjacent cell size is 20 μm and the total cell count per peloton is nearly 3 billion. The simulations are validated by four wind- tunnel tests, including one with a peloton of 121 models. The results show that the drag of all cyclists in the peloton decreases compared to that of an isolated rider. In the mid rear of the peloton it reduces down to 5%–10% that of an isolated rider. This corresponds to an “equivalent cycling speed” that is 4.5 to 3.2 times less than the peloton speed. These results can be used to improve cycling strategies
