Triggering Open Innovation Processes Through Organizational Emotional Capability and Rival's Absorptive Capacity Orientation
2022
In this article, we analyze the direct effects of the open innovation (OI) processes of acquisition and exploitation on innovation performance (IP), as well as the effects of two antecedents of OI: organizational emotional capability (EC) and rivaĺs absorptive capacity orientation (RACO). RACO implies processing external information in an analytical manner, whereas an intuitive approach is implicit in EC. The research model is tested in a sample of medium-low-technology Colombian small and medium-sized enterprises (SMEs) using structural equations by the consistent partial least squares method. Our results provide evidence on a significant effect of the OI acquisition process on IP, as well…
Integration Issues of Distributed Generators Considering Faults in Electrical Distribution Networks
2014
In the recent years there is a great interest in integration of distributed generation (DG) units at distribution level; this integration leads to planning as well as operational challenges. Some possibilities to handle grid planning issues are addressed in this paper. Effects on grid protection, fault current level, and voltage profile are investigated and described for different types of DG units; the classification of DG units is based on their terminal characteristics in terms of real and reactive power delivering capability. Different scenarios for mis-coordination problems caused by DG interconnection are discussed. The effect of the DG on the voltage profile of a distribution network…
Exchange Rate and Interest-Rate Driven Competitive Advantages in the EMU
2002
Real exchange and interest rates may still fluctuate inside the EMU and give rise to changes in competitiveness. We find, in contrast to what is generally expected, no convergence in these variables after the introduction of the euro. On the contrary, a divergence is found that is extraordinary when compared to the preceding 40 years. The magnitude of the divergence should urge on a wave of restructuring in the EMU, conditioned upon adequate policy responses. The worst-case scenario involves a flight to structural support and protectionism, challenging the whole idea of the EMU.
Multifunctional CD4(+) T cells correlate with active Mycobacterium tuberculosis infection.
2010
Th1 CD4(+) T cells and their derived cytokines are crucial for protection against Mycobacterium tuberculosis. Using multiparametic flow cytometry, we have evaluated the distribution of seven distinct functional states (IFN-gamma/IL-2/TNF-alpha triple expressors, IFN-gamma/IL-2, IFN-gamma/TNF-alpha or TNF-alpha/IL-2 double expressors or IFN-gamma, IL-2 or TNF-alpha single expressors) of CD4(+) T cells in individuals with latent M. tuberculosis infection (LTBI) and active tuberculosis (TB). We found that triple expressors, while detectable in 85-90%TB patients, were only present in 10-15% of LTBI subjects. On the contrary, LTBI subjects had significantly higher (12- to 15-fold) proportions of…
A Combination of Celecoxib and Glucosamine Sulfate Has Anti-Inflammatory and Chondroprotective Effects: Results from an In Vitro Study on Human Osteo…
2021
This study investigated the possible anti-inflammatory and chondroprotective effects of a combination of celecoxib and prescription-grade glucosamine sulfate (GS) in human osteoarthritic (OA) chondrocytes and their possible mechanism of action. Chondrocytes were treated with celecoxib (1.85 µM) and GS (9 µM), alone or in combination with IL-1β (10 ng/mL) and a specific nuclear factor (NF)-κB inhibitor (BAY-11-7082, 1 µM). Gene expression and release of some pro-inflammatory mediators, metalloproteinases (MMPs), and type II collagen (Col2a1) were evaluated by qRT-PCR and ELISA
Monte Carlo evaluation of kerma in an HDR brachytherapy bunker
2004
In recent years, the use of high dose rate (HDR) after-loader machines has greatly increased due to the shift from traditional Cs-137/Ir-192 low dose rate (LDR) to HDR brachytherapy. The method used to calculate the required concrete and, where appropriate, lead shielding in the door is based on analytical methods provided by documents published by the ICRP, the IAEA and the NCRP. The purpose of this study is to perform a more realistic kerma evaluation at the entrance maze door of an HDR bunker using the Monte Carlo code GEANT4. The Monte Carlo results were validated experimentally. The spectrum at the maze entrance door, obtained with Monte Carlo, has an average energy of about 110 keV, m…

Protecting Human Subjects in Internet Research
2005
The growth of the Internet as a research venue has led to practical, legal, and ethical problems regarding the protection of human subjects. Among these are difficulty in verifying subjects’ identities, gaining informed consent, and assuring ethically- correct research. The authors summarize the current standards pertaining to the protection of human subjects in online research and present a set of guidelines for dealing ethically, legally, and practically with the issues of privacy and confidentiality, intellectual property, informed consent, and protection from harm. As computer-mediated communications merge and evolve, as the Internet becomes more and more a part of everyday life, and as…
Il dovere di soccorso in mare e il diritto di obbedire al diritto (internazionale) del comandante della nave privata
2019
Shipmasters are commonly considered the addressees of an international legal duty to rescue at sea. This article describes the evolution of international law in this field, from the first maritime conventions of the 1910's to the IMO Safety Committee's resolutions of the 2010's. It then argues that behind the duty to rescue there is a hidden right of the shipmaster. This right has a moral pedigree and is functional to the full compliance of the duty itself. It can be enforced in the national legal order against any State (or private entity) that tries to obstruct the shipmaster's activities of assistance or to penalize her or him for the assistance given. National judges enforce this right …
The Functionality of Farmer Organisations and Their Role in Land Issues (La Fonctionnalite Institutionnelle Des Organisations Paysannes Et Leur Role …
2008
This is the final report of a study conducted with participative methods in Guinea, West Africa. The study analyses the functionality of small farmer organisations and the role they play in agricultural land issues. After a short introduction in chapter 1, we identify the macro-sociological context of the study as well as its importance for the country's development in chapter 2. The following chapter 3 treats the context of land use and land rights in the Fouta Djallon region as well as more specifically in our intervention zone. The empirical part in chapter 4 analyses the functionality of a range of small farmer organisations in the sub-prefecture Hind, prefecture Lab. In the following c…
