How selection of collaborating partners impact on the green performance of global businesses? An empirical study of green sustainability
2020
In recent days, both collaboration and sustainability have become an integral part of many global supply chains to achieve business excellence. Although previous literature and actual practices confirmed the successful implementation of sustainability practices through supply chain collaborations, it is not clear how collaborating partners can support financial and environmental performance, and hence strengthen the partnership performance in the global supply chains. To address this practice-based research question, we test the theoretical underpinning of suppliers and logistics partners in relation to required skills selection. We capture the depth of interdependencies in collaborations f…
Safety regulations : implications of the new risk perspectives
2016
Abstract The current safety regulations for industrial activities are to a large extent functionally oriented and risk-based (informed), expressing what to achieve rather than the means and solutions needed. They are founded on a probability-based perspective on risk, with the use of risk assessment, risk acceptance criteria and tolerability limits. In recent years several risk researchers have argued for the adoption of some new types of risk perspectives which highlight uncertainties rather than probabilities in the way risk is defined, the point being to better reflect the knowledge, and lack of knowledge, dimension of risk. The Norwegian Petroleum Safety Authority has recently implement…
Dwuizbowy parlament i reformy instytucjonalne w Republice Włoskiej
2019
Parliaments are dual institutions by nature, as they connect society with the legal structure of the state power. An analysis of the structural properties of contemporary legislative bodies indicates the particular importance of the factor of internal organization, which makes it possible to distinguish a symmetrical bicameralism. The case of Italy is attractive for researchers of political systems for many reasons. One of them is a fact, that both chambers hold the identical legal and political positions, have the same five years’ terms of office and identical scopes of authority. The proportional voting system guaranteed (with two exceptions) that the legislative branch was a mirror image…
Znaczenie unijnego systemu wjazdu/wyjazdu dla wzmocnienia bezpieczeństwa i skutecznego zarządzania granicami zewnętrznymi
2019
The importance of the EU Entry/Exit System to strengthen the security and effective management of the EU’s external borders The European Union strives for modern and effective border management through the use of the new technologies. This study concerns the adopted on 30 November 2017 EU Entry/Exit System. This system, which is expected to become fully operational by 2020, should contribute to the acceleration of border controls at the external borders of the Schengen area and increase the freedom of movement while enhancing the Union’s internal security. In addition, it is currently replacing the existing system of manual stamping of passports and will register electronic data on entries/…
Hacia una comprensión neurocientífica del trastorno por estrés postraumático en las víctimas del atentado terrorista del 11 de septiembre de 2001
2018
Resumen Introduccion De todas las personas expuestas a un evento traumatico, solo un pequeno porcentaje de ellas desarrollaran un trastorno por estres postraumatico (TEPT). Las neurociencias han sugerido la existencia de cierta predisposicion genetica que elevaria la vulnerabilidad para desarrollar el trastorno, asi como la desregulacion de multiples sistemas neuroquimicos como correlatos del trastorno. Asimismo, se ha hipotetizado sobre la posible transmision intergeneracional del mencionado trastorno. Material y metodo Revisar y sintetizar los resultados obtenidos sobre los factores psicobiologicos que aumentan la vulnerabilidad para desarrollar el TEPT tras el atentado terrorista de las …
Inducción de manía por inhibidores de la colinesterasa: evidencia empírica a través de datos observacionales
2019
Resumen Objetivos Evaluar si los inhibidores de la colinesterasa pueden inducir mania, y determinar si este efecto puede estar relacionado con estados u otras caracteristicas previas de los pacientes. Metodo Se realizo una revision sistematica, incluyendo articulos publicados en ISI Web of Knowledge y PubMed, desde enero de 1990 a marzo de 2018, siguiendo criterios PRISMA. Resultados De 326 estudios identificados, se incluyeron en la revision 16. En los casos comunicados hay una correlacion entre la introduccion de un inhibidor de la colinesterasa y la aparicion de un episodio maniaco/hipomaniaco. El riesgo parece ser mayor si el paciente tiene antecedentes de trastorno afectivo y si esta t…
An in vitro cyclic fatigue resistance comparison of conventional and new generation nickel-titanium rotary files
2018
Background New designs and processing of Niquel-Titanium (NiTi) have been introduced to increase resistance to cyclic fatigue. The purpose of this study was to compare the cyclic fatigue resistance of 3 NiTi rotary instruments, ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland), Profile Vortex Blue (PVB; Dentsply Tulsa Dental, Tulsa, OK, USA) and ProTaper Universal (PTU; Dentsply Maillefer, Ballaigues, Switzerland). Material and Methods A cyclic fatigue test was conducted operating instruments from ProTaper Next X2, Profile Vortex Blue 25.06 and ProTaper F2. A total of 234 instruments were rotated in 2 simulated stainless steel curved canals with different angles of curvature …
Generation of oxysterols formed by free radicals and enzymes by electrochemical oxidation
2016
International audience; It is commonly accepted that cholesterol oxide derivatives, also named oxysterols, are 27 carbon-atom molecules deriving either from enzymatic and non-enzymatic oxidation of cholesterol. Most of these compounds can be synthesized by more or less difficult and time consuming chemical reactions, and some of them have been discovered before the identification of the enzymes [mainly cytochrome P450 enzymes (CYP enzymes)] involved in their biosynthesis. A wide range of biological activities depends on oxysterols. Some oxysterols are also involved in the synthesis of cholesterol metabolites which have various properties. The paper by Weber et al. in this issue of European …
Perspectives of lupine wholemeal protein and protein isolates biodegradation
2018
Lupine (Lupinus angustifolius L.) protein (in wholemeal and protein isolates) was biodegraded using Pediococcus acidilactici in submerged and solid‐state fermentation conditions. The changes in the molecular weight of lupine protein fractions, amino acid (AA) profile, biogenic amine formation, antimicrobial and antioxidant properties, and protein digestibility in vitro and in vivo (in Wistar rats) were evaluated. After biotreatment, lower molecular weight peptides (from 10 to 20 kDa) were established, and the free AA content increased. Biodegradation improved the antioxidant properties, modulated the antimicrobial properties, and led to higher in vitro and in vivo digestibility and function…
Comparative Chemical Composition and Bioactivity of Opuntia ficus‐indica Sanguigna and Surfarina Seed Oils Obtained by Traditional and Ultrasound‐Ass…
2018
This study investigates the seed oils obtained from two different varieties of Opuntia ficus-indica (Sanguigna and Surfarina) growing in Sicily, Italy. Soxhlet and ultrasound-assisted extraction procedures are used to obtain the seed oils. The fatty acid profile, γ-tocopherols, carotenoid content, and the bioactivity in terms of the antioxidant effects (using ABTS, DPPH, FRAP, and β-carotene bleaching tests), and carbohydrate-hydrolysing enzyme inhibitory activity (α-amylase and α-glucosidase) are determined. The extraction procedure does not significantly affect the fatty acid composition of the oil, but it does affect the tocopherol and carotenoid contents, as well as the antioxidant and …
