El reto de la internacionalización para las Pequeñas y Medianas Empresas españolas

2017

While many studies have widely worked out on finding out the different relationships underlying the birth and prompt development of Small and Medium Enterprises (SMEs), we argue that getting an in depth approach to the problematic scene that takes place once they are keen on having a successful internationalization plan may have been understudied. Therefore, the aim of this research is that of identifying critical challenges faced by Spanish SMEs during an internationalization process. We do so by taking a qualitative approach. The current research contributes to the literature by adding new and renewed perspectives to the field, thanks to the qualitative analysis carried out through four i…

Entrepreneurial success and human resources

2011

PurposeThis paper aims to determine factors that have an influence on human resource management and entrepreneurial success in the context of European innovative small and medium‐sized enterprises (SMEs).Design/methodology/approachA primary test questionnaire was tested with 50 Spanish entrepreneurs. The feedback from this study was used to improve the survey for a final test. Multivariate regression analysis was used to differentiate the factors that allow the explanation of the variables to be studied and factors that, a priori, seem to be the most relevant in explaining entrepreneurial success.FindingsThe study allows the determination of what factors make the European entrepreneur succe…

Dynamics of structural change in agriculture, transaction cost theory and market efficiency: The case of cultivation contracts between agricultural e…

2022

In developed economies, the increasing openness of markets, the ease of trade and the speed of information lead to territorial imbalance and marginalization phenomena of small agricultural activities that cannot compete with the new models of agri-food systems. In this research, starting from this situation, we analyze through the Transaction Cost Theory what can be practised too recover competitiveness margins for small farms. From the study, it emerges that cultivation contracts represent a valid tool for the solution of various marginalization problems of many agricultural enterprises. In particular, from the experience gained over the past few years in Sicily, the cultivation contract b…

This article describes research concerning push-and-pull enteroscopy. Clear and possible indications for this technique are highlighted.

High pressure treatment and green tea extract synergistically control enteric virus contamination in beverages

2022

Consumers are driving food production toward the use of natural preservatives and minimal processing technologies. Green tea extract (GTE) at low concentration could be combined with high pressure processing (HPP) for reduced treatment times and quality impact on foods in a hurdle concept for synergistic effects on foodborne viral pathogens, specifically human norovirus and hepatitis A virus (HAV). Viral inactivation by HPP (at 300, 400, and 500 MPa for 5 min) combined with 3.3 mg/mL aged-GTE was initially evaluated in buffer (PBS) against murine norovirus (MNV), a culturable human norovirus surrogate, and HAV. Furthermore, human norovirus inactivation was evaluated by the novel human intes…

Ambiguous Role of Interleukin-12 in Yersinia enterocolitica Infection in Susceptible and Resistant Mouse Strains

1998

ABSTRACT Endogenous interleukin-12 (IL-12) mediates protection against Yersinia enterocolitica in C57BL/6 mice by triggering gamma interferon (IFN-γ) production in NK and CD4 + T cells. Administration of exogenous IL-12 confers protection against yersiniae in Yersinia -susceptible BALB/c mice but exacerbates yersiniosis in resistant C57BL/6 mice. Therefore, we wanted to dissect the different mechanisms exerted by IL-12 during Yersinia infections by using different models of Yersinia -resistant and -susceptible mice, including resistant C57BL/6 mice, susceptible BALB/c mice, intermediate-susceptible wild-type 129/Sv mice, 129/Sv IFN-γ-receptor-deficient (IFN-γR −/− ) mice and C57BL/6 tumor n…

Treated wastewaters discharged from wastewater treatment plants (WWTP) and livestock effluents are the main sources of contamination of aquatic environments and of agricultural soils by human and animal fecal micro-organisms. Contaminated waters, especially bathing waters, may present a sanitary risk for humans if the concentrations of fecal micro-organisms are high, thus indicating the potential presence of pathogenic and/or antibiotic resistant strains. Soils and crops also can be contaminated by these micro-organisms when treated wastewaters are used to irrigate cultivated soils. Consequently, microbiological quality controls are mandatory for bathing waters and treated wastewaters to ma…

Effects of adjuvants of the cholera toxin family on CD4 + T cell responses in a murine model of intrarectal immunization with rotavirus-like particles

2011

Mucosal immunization is an important goal of vaccine development to protect against pathogens that use mucosa as portals of entry. However, the use of non-replicating antigens requires the addition of adjuvants.Cholera-like enterotoxins, cholera toxin (CT) from Vibrio cholerae and the heat-labile enterotoxin (LT) from toxinogenic strains of E. coli, as well as the mutant LR-192G and their B subunits (CTB and LTB) have been shown to increase immune responses against unrelated co-administered antigens by mucosal routes. However, their mechanism of action is very complex and not completely understood and differences exist between holotoxins and B subunits and within molecules, differences exis…
