The Strategic Cognition View of Issue Salience and the Evolution of a Political Issue: Landis & Gyr, the Hungarian Uprising and East-West Trade, …
2017
Why do firms facing similar stakeholder issues respond quite differently? The recently introduced strategic cognition view of issue salience and firm responsiveness (hereinafter: issue salience model) seeks to tackle this core question of stakeholder theory. I extend the nascent theorizing with a historical case study in order to rethink the model’s firm-centric perspective. The firm under examination in this historical case study is the Swiss multinational Landis & Gyr (LG) during the Cold War period. Like many other Swiss export-oriented companies in the 1950s and early 1960s, LG was challenged by Swiss pressure groups, which were highly effective at putting an issue on the public agenda:…
Protein-Based Nanoparticles for the Delivery of Enzymes with Antibacterial Activity.
2018
Proteins represent a versatile biopolymer material for the preparation of nanoparticles due to their biocompatibility, biodegradability, and low immunogenicity. This study presents a protein-based nanoparticle system consisting of high surface PEGylated lysozyme polyethylene glycol-modified lysozyme (LYZmPEG ). This protein modification leads to a solubility switch, which allows a nanoparticle preparation using a mild double emulsion method without the need of surfactants. The method allows the encapsulation of large hydrophilic payloads inside of the protein-based nanoparticle system. Native lysozyme (LYZ) was chosen as payload because of its innate activity as natural antibiotic. The mild…
Isolation and partial characterization of antagonistic peptides produced by Paenibacillus sp. strain B2 isolated from the sorghum mycorrhizosphere.
2005
ABSTRACT Paenibacillus sp. strain B2, isolated from the mycorrhizosphere of sorghum colonized by Glomus mosseae , produces an antagonistic factor. This factor has a broad spectrum of activity against gram-positive and gram-negative bacteria and also against fungi. The antagonistic factor was isolated from the bacterial culture medium and purified by cation-exchange, reverse-phase, and size exclusion chromatography. The purified factor could be separated into three active compounds following characterization by amino acid analysis and by combined reverse-phase chromatography and mass spectrometry (liquid chromatography-mass spectrometry and mass spectrometry-mass spectrometry). The first com…
CD8+CD45RA+CD27-CD28-T-cell subset in PBL of cervical cancer patients representing CD8+T-cells being able to recognize cervical cancer associated ant…
2003
Objective In response to antigenic stimulation, naive MHC-class I restricted and antigen-specific CD8+CD45RA+CD28+T-cells undergo clonal expansion and differentiate into CD8+CD45RO+ memory T-cells. Upon re- encounter with the nominal antigen, CD45RO+ T-cells are able to convert to CD8+CD45RA+CD28-T-cells displaying potent immune effector functions, including TNF-alpha production. This T-cell subpopulation constitutes a minor population in healthy individuals. In the present study we are currently evaluating whether this particular T-cell subset in PBL represents CD8+T-cells which may be able to recognize cervical cancer associated antigens provided by HPV 16 E7. Material and methods Flow-cy…
Position Statement on Breastfeeding from the Italian Pediatric Societies
2015
The 2015 Position Statement on Breastfeeding of The Italian Pediatric Societies (SIP, SIN, SICupp, SIGENP) recognizes breastfeeding as an healthy behaviour with many short and long term benefits for both mother and infant. While protecting, promoting and supporting breastfeeding, neonatologists and pediatricians need specific knowledge, skills and a positive attitude toward breastfeeding. In Maternity Hospitals and in Neonatal Units, appropriate organizative interventions should be applied in order to facilitate the beginning of breastfeeding and the use of mother’s/human milk. The Italian Pediatric Societies indicate the desiderable goal of around 6 months exclusive breastfeeding if the in…
Stability and l1-gain analysis for positive 2D T–S fuzzy state-delayed systems in the second FM model
2014
This paper considers the problems of delay-dependent stability and l"1-gain analysis for a class of positive two-dimensional (2D) Takagi-Sugeno (T-S) fuzzy linear systems with state delays described by the second FM model. Firstly, the co-positive type Lyapunov function method is applied to establish sufficient conditions of asymptotical stability for the addressed positive 2D T-S fuzzy system. Then, the l"1-gain performance analysis for the positive 2D T-S fuzzy delayed system is studied. All the obtained results are formulated in the form of linear matrix inequalities (LMIs) which are computationally tractable. Finally, an illustrative example is given to verify the effectiveness of the p…
Towards the Environmental Sustainability of the Construction Sector: Life Cycle Environmental Impacts of Buildings Retrofit
2022
In the context of the need for carbon emissions reduction, the buildingsector, as one of the most energy intensive one, needs tools and approaches towards carbon neutrality and the increase of the buildings overall energy performances. The paper proposes an integrated approach towards the environmental performances analysis of a small neighborhood having as goal the achievement of the Positive Energy District target and the assessment of its environmental impacts. The methodology proposed includes building modeling and dynamic energy simulation using the Energy Plus engine and a simplified Life Cycle Assessment approach. Two scenarios are investigated: i) the existing neighborhood, ii) the …
"My Best Self": Efficacy and underlying mechanisms of a Positive Psychology Intervention
2018
Las Intervenciones de Psicología Positiva son recursos valiosos para promover el bienestar en los individuos que las practican (Bolier et al., 2013), y, concretamente, la intervención del Mejor Yo Posible (MYP) parece ser un enfoque prometedor (Loveday et al., 2016). Se trata de una intervención positiva que pide a los individuos que se imaginen a sí mismos en el mejor futuro posible (King, 2001). Aunque existen muchos estudios individuales publicados acerca de su eficacia, todavía se desconoce cuál es la eficacia general de esta intervención, y se necesita investigación adicional sobre este tema. Además, la investigación sobre los mecanismos que subyacen a la eficacia de esta actividad pos…
Validation of a Modified Version of the Psychological Capital Questionnaire (PCQ12) in Spain
2018
Background : Previous studies have found some limitations and inconsistencies in the functioning of the short Psychological Capital Questionnaire (PCQ12), suggesting the need to improve it. The objective of the current study is to validate a modified version of the PCQ12 in Spain. Method : The sample consists of 792 employees from 42 Spanish organizations. A cross-validation was carried out to test the factorial validity of the modified scale. Reliability and convergent, discriminant, and criterion validity were also tested. Results : The modified PCQ12 showed good psychometric qualities. A four-factor structure showed a better fit to the data than the original second-order structure. Conc…
