- This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of science and technology. [RIDE is also supposed to be realized in subsequent stages of development depending on the assigned priorities.

- Ten conceptually different models were applied to predict the discharge from the 6 ha artificial Chicken Creek catchment in Lausatia, North-East Germany, which has been created in an open cast mining area. The study consisted of three steps to make a model intercomparison with the objective of a priori prediction of the water balance and the discharge dynamics. In order to test the ability of each model and modeller to predict water flows in an ungauged catchment, only soil texture, topography, vegetation coverage and climate data were provided to the modellers in the first step. Hydrological data on discharge, soil moisture and groundwater levels were withheld. This enabled us to assess the predictive capabilities of the models under sparse data conditions. The predicted components of the water balance varied in a wide range. None of the model simulations came close to the observed water balance for the entire 3-year study period. Discharge was mainly predicted as subsurface flow with little surface runoff. In reality, surface runoff was a major flow component despite the fairly coarse soil texture. In the second step, additional process knowledge was gained during a joint field visit. The occurence of gully erosion and surface crusting was detected and implemented into the models. Consequently, model predictions changed considerably. The previous simulations dominated by subsurface flow changed to surface flow-dominated simulations. Additional data, provided in the third step, mainly confirmed the parameterisations and assisted in a better definition of initial conditions and subsurface storage. The comparison indicates that, in addition to model philosophy, the personal judgement of the modellers was a major source of the differences in the model results. The model parameterisation and choice of initial conditions depended on the modeller's judgement and were therefore a result of the modellers' experience in terms of model types and case studies.

- Ten conceptually different models in predicting discharge from the artificial Chicken Creek catchment in North-East Germany were used for this study. Soil texture and topography data were given to the modellers, but discharge data was withheld. We compare the predictions with the measurements from the 6 ha catchment and discuss the conceptualization and parameterization of the models. The predictions vary in a wide range, e.g. with the predicted actual evapotranspiration ranging from 88 to 579 mm/y and the discharge from 19 to 346 mm/y. The predicted components of the hydrological cycle deviated systematically from the observations, which were not known to the modellers. Discharge was mainly predicted as subsurface discharge with little direct runoff. In reality, surface runoff was a major flow component despite the fairly coarse soil texture. The actual evapotranspiration (AET) and the ratio between actual and potential ET was systematically overestimated by nine of the ten models. None of the model simulations came even close to the observed water balance for the entire 3-year study period. The comparison indicates that the personal judgement of the modellers was a major source of the differences between the model results. The most important parameters to be presumed were the soil parameters and the initial soil-water content while plant parameterization had, in this particular case of sparse vegetation, only a minor influence on the results.

- In practice, the catchment hydrologist is often confronted with the task of predicting discharge without having the needed records for calibration. Here, we report the discharge predictions of 10 modellers - using the model of their choice - for the man-made Chicken Creek catchment (6 ha, northeast Germany, Gerwin et al., 2009b) and we analyse how well they improved their prediction in three steps based on adding information prior to each following step. The modellers predicted the catchment's hydrological response in its initial phase without having access to the observed records. They used conceptually different physically based models and their modelling experience differed largely. Hence, they encountered two problems: (i) to simulate discharge for an ungauged catchment and (ii) using models that were developed for catchments, which are not in a state of landscape transformation. The prediction exercise was organized in three steps: (1) for the first prediction the modellers received a basic data set describing the catchment to a degree somewhat more complete than usually available for a priori predictions of ungauged catchments; they did not obtain information on stream flow, soil moisture, nor groundwater response and had therefore to guess the initial conditions; (2) before the second prediction they inspected the catchment on-site and discussed their first prediction attempt; (3) for their third prediction they were offered additional data by charging them pro forma with the costs for obtaining this additional information. Hollander et al. (2009) discussed the range of predictions obtained in step (1). Here, we detail the modeller's assumptions and decisions in accounting for the various processes. We document the prediction progress as well as the learning process resulting from the availability of added information. For the second and third steps, the progress in prediction quality is evaluated in relation to individual modelling experience and costs of added information. In this qualitative analysis of a statistically small number of predictions we learned (i) that soft information such as the modeller's system understanding is as important as the model itself (hard information), (ii) that the sequence of modelling steps matters (field visit, interactions between differently experienced experts, choice of model, selection of available data, and methods for parameter guessing), and (iii) that added process understanding can be as efficient as adding data for improving parameters needed to satisfy model requirements.

Leveraging Resources For Innovation : The Role of Synchronization

- Leveraging resources to develop innovation is central to exploiting market opportunities yet doing so is complex and fraught with challenges. This study explores some of this complexity by theoretically detailing and empirically examining the critical role that synchronization plays in the process of leveraging resources to create innovation. Specifically, we integrate resource orchestration with the behavioral theory of the firm to investigate the joint effect of synchronization and leveraging strategies on innovation under different performance conditions. Using policy capturing methodology resulting in 3,600 observations from 120 managers, we find empirical evidence that synchronization can enhance innovation outcomes of all leveraging strategies. Yet, this positive synergistic effect occurs in high performing firms that use the resource advantage and market opportunity leveraging strategies and in low performing firms that use the entrepreneurial leveraging strategy. Our theory and results offer important contributions to the innovation and resource orchestration literatures. First, our study offers a contextually rich examination of innovation, suggesting that it is not only resources, but also managerial actions and a firm?s relative performance that drive innovation outcomes. Specifically, this study adds to our knowledge of the relationship between resources and innovation strategies by investigating the impact of synchronization ? a key contingency in understanding the effects of resources on innovation. Second, we examine boundary conditions of synchronization?s influence by integrating behavioral logic in the context of relative firm performance. Mixed evidence exists on the synergistic effect of valuable capabilities, with some studies showing increased gains and others finding evidence of a neutral relationship. This study begins to disentangle these findings by suggesting that resource leveraging strategies and synchronization together enhance innovation when the strategy aligns with the firm?s relative performance aspirations, answering calls for the development of a more nuanced understanding of the pursuit of innovation.

Entrepreneurial Orientation, Generational Involvement and Participative Strategy: A Configurational Approach to Performance in Family Firms
- 2011

Konferensbidrag (refereegranskat)abstract
- To better understand the entrepreneurship in family firms, we consider the joint interaction effect of entrepreneurial orientation (EO), generational involvement and participative strategy. Drawing on the logic of resource orchestration, we argue that participative strategy acts as a coordinating mechanism that not only mitigates the relational conflict that increased generational involvement generates when mobilized EO, but also enhances family firms' ability to utilize the heterogeneous, yet complementary knowledge and experiences generational involvement offers. Configuring participative strategy and EO with generational involvement provides the direction and coordination needed to unlock the potential value of these unique resources. Our theory suggests that realizing the benefits from entrepreneurship in family firms is a complicated matter, affected by the configuration of EO, generational involvement and participative strategy.

Orchestrating resources with suppliers for product innovation
- 2023

Ingår i: The Journal of product innovation management. - : John Wiley & Sons. - 0737-6782 .- 1540-5885.

Tidskriftsartikel (refereegranskat)abstract
- How orchestrating external, supplier-provided resources affects product innovation is an important question. While product innovation is essential to achieve a competitive advantage, it is costly as it requires significant investments. It thus puts a severe strain on firm resources, which is particularly critical for resource-scarce small–medium enterprises (SMEs). Therefore, these firms must combine their own resources with those of external parties, particularly suppliers, to enhance their product innovation. However, knowledge about how orchestrating these resources affects product innovation is limited, because empirical studies on resource orchestration have largely focused on firm-internal resources; furthermore, there is ambiguity regarding the extent to which drawing on external resources is beneficial. In addition, the conditions that affect the resource orchestration–product innovation relationship remain unexplored. Therefore, we focus on supplier logistics integration (SLI), an important resource orchestration action referring to the orchestration of external, supplier-provided resources; we draw on the resource orchestration framework and the related work on organizational rigidity to theorize that there is an inverted U-shaped relationship between SLI and product innovation. Additionally, we suggest that learning orientation and environmental dynamism mitigate rigidities associated with high levels of SLI and thus facilitate the translation of SLI into product innovation. Testing our hypotheses with data from Swedish SMEs supports our theorizing and provides important contributions. Most importantly, we extend the resource orchestration framework to include the focus on external, supplier-provided resources, thereby advancing our knowledge and understanding of resource orchestration for product innovation in SMEs.

Resource orchestration in family firms : Investigating how entrepreneurial orientation, generational involvement, and participative strategy affect performance

Tidskriftsartikel (refereegranskat)abstract
- Drawing on the process of resource orchestration, we argue a co-alignment of multiple factors is needed for family firms to increase performance through entrepreneurship. Specifically, we posit that entrepreneurial orientation provides the mobilizing vision to use the heterogeneous yet complementary knowledge and experiences offered by increased generational involvement toward entrepreneurship. However, without a coordinating mechanism, generational involvement leads to conflict and negative outcomes. When, instead, it is also coordinated via a participative strategy, performance gains are achieved. In sum, results suggest that realizing the benefits from entrepreneurship in family firms is a complicated matter affected by the synchronization of entrepreneurial orientation, generational involvement, and participative strategy.
