Influence of economic crisis on new SME survival: reality or fiction?
2016
AbstractThe aim of this research was to analyse the survival of new ventures during periods of economic crisis. The article compares survival probability during growth and crisis periods. An empirical study was used to analyse new venture survival probability. Results show that new firms have a greater likelihood of surviving during crisis periods than they do during growth periods. An additional aim of the study was to analyse the survival probability of opportunity and necessity entrepreneurs during crisis periods. Results show that gaps in survival likelihood between opportunity and necessity entrepreneurship are bigger during times of crisis than they are during growth periods.
Italy: money transfer, money laundering and intermediary liability
2020
Purpose This paper aims to offer a general overview of money transfers in Italy and Europe focussing specifically on the migrant community. This is of particular interest because it is in that community where money transfers are most prevalent. This shows the money transfer system as a tool that could guarantee the financial inclusion of migrants but at the same time being used in a distorted and unlawful manner. Design/methodology/approach After a brief introduction focussed on working principles and legal frameworks, the paper will go deeper in evaluating money transfer data. This data, which comes from various legal authorities, will show the extent to which different migrant communitie…
FRONTIER RESEARCH IN TORNEDALEN
1970
Publisher Summary This chapter highlights frontier research in Tornedalen. In view of the general alignment of the research carried on by ethnologists, it is a matter of course that a concentration of interest to regions with administrative boundaries of such a marked character as, for example, national frontiers may often give a sharper relief to the problems considered. The interest in questions around such boundaries here leads to inter-Nordic collaboration. This is what has happened in Tornedalen, the frontier zone between Finland and Sweden. The problems around a frontier dividing a coherent settled area make themselves felt in all sectors of human community life, and, they cannot be i…
Family and Affective Models in Children's Literature. An Approach from the Texts for Early Readers at Valencian Schools
2015
Abstract In previous researches we have offered a panoramic view about the presence of family structures different from the traditional one in children's literature, (Oltra Albiach, 2011), about the (shy) presence of protagonists with homo-parent, single- parent families reconstructed or intercultural in children's titles and about the publications of these characteristics in the literature for first readers that have seen the light in recent years (Oltra Albiach & Pardo Coy, 2013). It is noted that the introduction of these literatures in initial schools remains in general a pending matter, especially if we take into account that it is an ideal level to prevent and treat stereotypes and pr…
Nanog Regulates Primordial Germ Cell Migration Through Cxcr4b
2010
Abstract Gonadal development in vertebrates depends on the early determination of primordial germ cells (PGCs) and their correct migration to the sites where the gonads develop. Several genes have been implicated in PGC specification and migration in vertebrates. Additionally, some of the genes associated with pluripotency, such as Oct4 and Nanog, are expressed in PGCs and gonads, suggesting a role for these genes in maintaining pluripotency of the germ lineage, which may be considered the only cell type that perpetually maintains stemness properties. Here, we report that medaka Nanog (Ol-Nanog) is expressed in the developing PGCs. Depletion of Ol-Nanog protein causes aberrant migration of …
Nanog Regulates Proliferation During Early Fish Development
2009
Abstract Nanog is involved in controlling pluripotency and differentiation of stem cells in vitro. However, its function in vivo has been studied only in mouse embryos and various reports suggest that Nanog may not be required for the regulation of differentiation. To better understand endogenous Nanog function, more animal models should be introduced to complement the murine model. Here, we have identified the homolog of the mammalian Nanog gene in teleost fish and describe the endogenous expression of Ol-Nanog mRNA and protein during medaka (Oryzias latipes) embryonic development and in the adult gonads. Using medaka fish as a vertebrate model to study Nanog function, we demonstrate that …
Characterization of PAMP/PRR interactions in European eel (Anguilla anguilla) macrophage-like primary cell cultures
2013
The eel (Anguilla anguilla) has been identified as a vulnerable species with stocks dramatically declining over the past decade. In an effort to support the species from overfishing of wild stocks increased interest in eel aquaculture has been notable. In order to expand the scarce knowledge concerning the biology of this species significant research efforts are required in several fields of biology. The development of cell culture systems to study the immune response is a key step towards an increased understanding of the immune response and to develop resources to support further study in this threatened species. Macrophages are one of the most important effector cells of the innate immun…
Structural and functional diversity of the lectin repertoire in teleost fish: Relevance to innate and adaptive immunity
2011
Protein–carbohydrate interactions mediated by lectins have been recognized as key components of innate immunity in vertebrates and invertebrates, not only for recognition of potential pathogens, but also for participating in downstream effector functions, such as their agglutination, immobilization, and complement-mediated opsonization and killing. More recently, lectins have been identified as critical regulators of mammalian adaptive immune responses. Fish are endowed with virtually all components of the mammalian adaptive immunity, and are equipped with a complex lectin repertoire. In this review, we discuss evidence suggesting that: (a) lectin repertoires in teleost fish are highly dive…
Priming of host resistance to protect cultured rainbow trout Oncorhynchus mykiss against eye flukes and parasite-induced cataracts
2010
In the present study, immunologically naive rainbow trout Oncorhynchus mykiss were experimentally exposed to a low-level Diplostomum spathaceum (Trematoda) infection to stimulate acquired resistance and, along with unexposed controls, were subsequently exposed to natural infection for 8 weeks. The priming of the host resistance, designed to simulate a procedure applicable in aquaculture, decreased the number of establishing parasites compared to untreated controls by the end of the experiment. This effect was slow and did not protect the fish against the parasite-induced cataracts. The results suggest that this type of priming of host resistance is probably inefficient in preventing the del…
Can lake restoration by fish removal improve the status of profundal macroinvertebrate assemblages?
2013
Summary Removal of fish to restore lake pelagic food webs and water quality has been shown to increase the abundance of benthic invertebrates in shallow areas due to decreased predation pressure, while responses of profundal macroinvertebrate assemblages are less well documented. We used multivariate analyses and a Before-After-Control-Impact design to assess the impacts of fish removal (in total 101 000 kg of percid and cyprinid fish) on profundal macroinvertebrate species composition and abundance and ecological status in two basins of a eutrophic boreal lake. In the deeper main basin, macroinvertebrate community composition and classification of ecological status were not affected by fis…
