Dynamic capabilities in e-health innovation: Implications for policies
2017
Abstract Objective To mitigate the effect of caregiver shortage, collaborative networks in Norwegian municipalities are exploring the possibilities provided by e-health and welfare technologies. However, extracting benefits from such technologies depends on many factors. Methods In this study, an extensive literature review is performed to compare e-health and other sectors in terms of the critical success factors in collaborative business process management. Using the dynamic capabilities view as a general theoretical lens, and a process orientation framework for operationalization, these factors are then conceptualized and validated in a cross-sectional study of cases in the Norwegian mun…
Eigenvectors of k–ψ-contractive wedge operators
2008
Abstract We present new boundary conditions under which the fixed point index of a strict- ψ -contractive wedge operator is zero. Then we investigate eigenvalues and corresponding eigenvectors of k – ψ -contractive wedge operators.
A pre-processing technique based on the wavelet transform for linear autoassociators with applications to face recognition
1997
In order to improve the performance of a linear autoassociator (which is a neural network model), we explore the use of several preprocessing techniques. The gist of our approach is to store, in addition to the original pattern, one or several pre-processed (i.e. filtered) versions of the patterns to be stored in a neural network. First, we compare the performance of several pre-processing techniques (a plain vanilla version of the autoassociator as a control, a Sobel operator, a Canny-Deriche operator, and a multiscale Canny-Deriche operator) on an example of a pattern completion task using a noise degraded version of a face stored in an autoassociator. We found that the multiscale Canny-D…
Intraspecific Differences in Spectral Reflectance Curves as Indicators of Reduced Vitality in High-Arctic Plants
2017
Remote sensing is a suitable candidate for monitoring rapid changes in Polar regions, offering high-resolution spectral, spatial and radiometric data. This paper focuses on the spectral properties of dominant plant species acquired during the first week of August 2015. Twenty-eight plots were selected, which could easily be identified in the field as well as on RapidEye satellite imagery. Spectral measurements of individual species were acquired, and heavy metal contamination stress factors were measured contemporaneously. As a result, a unique spectral library of dominant plant species, heavy metal concentrations and damage ratios were achieved with an indication that species-specific chan…
X-ray fluorescence analysis by the fundamental parameters method without explicit knowledge of the excitation beam spectrum
2000
The results of analyses carried out with the fundamental parameters method without explicit knowledge of the beam exciting the sample are presented. The excitation beam is described by means of the fluorescence produced by a set of thick or thin targets of pure chemical elements. The results are compared with those obtained by using a semi-empirical model and an adjusted spectrum model, all sets of results being in turn compared with the actual chemical composition of the samples. It is concluded that the description of the excitation beam by means of the fluorescence produced on targets of pure elements is suitable for use with the fundamental parameters method.

Comparison of Mechanical, Assisted and Manual Harvest of Origanum vulgare L.
2022
In Italy, the production of Origanum vulgare L. is lower than the national market demand, so there is an increasing interest in this crop, even if the manual harvest and bunch binding represent ca. 60% of the production cost. The aim of this work is to evaluate the harvest efficiency, as well as the working capacity, productivity and quality of mechanical harvesting by means of a reaper-binder designed for cereal and forage crops and assisted harvesting by means of a long-reach edge trimmer. In fact, the final aim is to suggest a machine and a method for oregano harvesting that could significantly reduce the time and, therefore, the cost of this crop operation, while achieving a product qua…
Structural Dynamics and Intentional Governance in Strategic Interorganizational Network Evolution: A Multilevel Approach
2016
This article aims to shed light on the drivers underlying the role and scope of intentional governance of the structural dynamics of whole interorganizational networks. Prior research has distinguished networks that are emergent from networks that are orchestrated. While empirical studies have shown situations in which the role and scope of intentional governance of whole interorganizational networks has changed in time, and there is a growing interest regarding the endogenous drivers of network dynamics, the dimensions that influence intentional governance of network structure dynamics and the way this is carried out remain still to be elucidated. In order to pinpoint these drivers, we le…
Learning culture and knowledge management processes: To what extent are they effectively related?
2014
In the contemporary context of high competitiveness between organizations, organizational learning culture and knowledge management (KM) have been considered key concepts in both academic and managerial settings. This study aims to provide empirical support for the relationship between organizational learning culture and knowledge management, specifically concerning the prediction of learning culture on KM processes. Data collection was carried out through questionnaires in 50 Portuguese manufacturing firms. Data was analyzed at the organizational level using standard multiple regressions. The results showed a significant and positive relationship between learning culture and KM practices. …
Hedging foreign exchange rate risk: Multi-currency diversification
2016
Abstract This article proposes a multi-currency cross-hedging strategy that minimizes the exchange risk. The use of derivatives in small and medium-sized enterprises (SMEs) is not common but, despite its complexity, can be interesting for those with international activities. In particular, the reduction in the exchange risk borne through the use of natural multi-currency cross-hedging is measured, considering Conditional Value-at-Risk (CVaR) and Value-at-Risk (VaR) for measuring market risk instead of the variance. CVaR is minimized using linear programmes, while a multiobjective genetic algorithm is designed for minimizing VaR, considering two scenarios for each currency. The results obtai…
Effectuating Person-Organization Fit : Effectuation in Organizations
2015
Industrial policies of innovation concentrate on funding or encouraging promising innovations entailing growth or that have possibilities of internationalization. However, concrete innovation process happens in and between individuals. Effectuation is a logic that is emergent and iterative in nature. It develops through enactment and trial-and-error processes that follow deep expertise, contextual experience and abilities to leverage contingencies. Harnessing individuals to challenge their working environment to function better may improve both work well-being and organization performance. The integration of person-organization fit and effectuation suggest that paying attention to effectuat…
