Organisational learning capability, product innovation performance and export intensity
2012
The hypothesis that managerial characteristics which facilitate the organisational learning process can provide firms with a basis for competitive advantage has received a great deal of attention. While there is evidence that organisational learning affects export intensity, we argue that intermediate variables, such as innovation, should be used in order to evaluate its impact in organisations. This study shows that firms with a higher organisational learning capability tend to be more innovative, and for this reason, they are more likely to export a higher share of their production. From a longitudinal perspective, we use structural equation modeling on a database from Italian and Spanish…
Transformational leadership and absorptive capacity: an analysis of the organisational catalysts for this relationship
2017
ABSTRACTResearch analysing the antecedents of a firm’s absorptive capacity suggests that transformational leadership (TL) is one of its main determinants. However, the few studies focusing on the relationship between these two variables do not explicitly assess why transformational leaders facilitate knowledge acquisition, sharing and retention inside firms. This paper suggests that the reason is that the former contributes to the creation of an organisational context that favours learning processes. We test our research model on a sample of 467 Spanish industrial firms. Findings provide evidence that TL is positively related to the firm’s absorptive capacity and that this relationship is m…
Do top- and mid-level managers view Enterprise Resource Planning (ERP) systems success measures differently?
2006
We investigated ERP systems success measurement from the perspectives of top- and mid-level managers. Using surveys in two small Northern European countries, we aimed to determine whether differences exist between the two groups. Our results showed that there are no significant statistical differences between the two groups. The implications of the findings for both practice and research are outlined.
Lattices of Jordan algebras
2010
AbstractCommutative Jordan algebras play a central part in orthogonal models. The generations of these algebras is studied and applied in deriving lattices of such algebras. These lattices constitute the natural framework for deriving new orthogonal models through factor aggregation and disaggregation.
Recruitment, knowledge integration and modes of innovation
2015
Abstract This paper investigates how the strength and intrinsic characteristics of firms’ knowledge bases and processing routines have evolved with the past inflow of employees. The empirical analysis is based on linked public register and innovation survey data for Norway. It finds that recruitment from universities, research institutes and higher education institutions has increased the capacity of firms to generate technical inventions. Yet, the organizational knowledge bases and processing routines on which commercial innovation output depends have been strengthened only by the recruitment that has occurred from related industries. Implications for research, management and policy are dr…
MuPix and ATLASPix -- Architectures and Results
2020
High Voltage Monolithic Active Pixel Sensors (HV-MAPS) are based on a commercial High Voltage CMOS process and collect charge by drift inside a reversely biased diode. HV-MAPS represent a promising technology for future pixel tracking detectors. Two recent developments are presented. The MuPix has a continuous readout and is being developed for the Mu3e experiment whereas the ATLASPix is being developed for LHC applications with a triggered readout. Both variants have a fully monolithic design including state machines, clock circuitries and serial drivers. Several prototypes and design variants were characterised in the lab and in testbeam campaigns to measure efficiencies, noise, time reso…
An affine scaling method using a class of differential barrier functions: primal approach
2020
International audience; In this paper we propose a family of affine scaling interior point algorithms, called galpv4, using a primal approach, based on a large class of differential barrier functions. We show that these algorithms are in fact an extension and generalization of the classical affine scaling algorithm based on the well-known log barrier function. After carrying out a complete convergence analysis, we select some of these algorithms for comparison with the classical affine scaling algorithm, performed with the help of the familiar Netlib test set.
Managing asymmetry in franchise contracts: transparency as the overriding rule
2012
PurposeThe aim of this article is to provide solutions to protect the weaker party in management and distribution contracts, especially in the field of franchising.Design/methodology/ approachThe paper is based on a review of literature, legislation and practices concerning management and franchise contracts. The regulation of this field at a national level consists of laws that are both private and mandatory in nature. Certain questions are raised concerning the obligatory nature of regulations when applied to the management of international franchise contracts.FindingsThis article studies the question of whether the imperative application of laws to international contract management is ap…
The minimal cost maximum matching of a graph (supplementary remarks)
1971
In addition to the preceding paper, it will be shown that (1) the matching problem is closely related to the linear assignment problem and how (2) this property can be taken advantage of for solving the matching problem.
Simulating term structure of interest rates with arbitrary marginals
2011
Decision models under uncertainty rely their analysis on scenarios of the economic factors. A key economic factor is the term structure of interest rates (yields). Simulation models of the yield curve usually assume that the conjugate distribution of the interest rates is lognormal. Dynamic models, like vector auto-regression, implicitly postulate that the logarithm of the interest rates is normally distributed. Statistical analyses have, however, shown that stationary transformations (yield changes) of the interest rates are substantially leptokurtic, thus posing serious doubts on the reliability of the available models. We propose in this paper a VARTA model (Biller and Nelson, 2003) to s…
