Range-wide phylogeography and taxonomy of the marine rock pools dweller Tigriopus fulvus (Fischer, 1860) (Copepoda, Harpacticoida)

2021

In the light of the wide distribution and ecological importance of the genus Tigriopus in coastal rock pool habitats, and of its frequent use in aquaculture and as a model organism, we investigated the identity of the Atlantic–Mediterranean Tigriopus populations and elucidated their taxonomy and patterns of morphological and genetic diversity. In order to reach these goals, an “integrative taxonomy” multisource approach was implemented. First, we investigated the constancy and taxonomical value of the morphological characters currently used to distinguish among the Tigriopus species occurring in the Mediterranean and in Eastern Atlantic area north of the Tropic of Cancer, and checked the ac…

Microbiology meets geochemistry: geothermal flux shapes different microbial communities at the same exhalative area

2015

Volcanic/geothermal areas are sites of complex interactions between geosphere and biosphere. Pantelleria island (Southern Mediterranean Sea) hosts a high enthalpy geothermal system characterized by high CH4 and low H2S fluxes. Two sites, FAV1 and FAV2, located a few meters apart at the main exhalative area of the island (Favara Grande), recorded similar physical conditions (soil temperature 60°C, soil gas composition enriched in CH4, H2 and CO2). However, while high methanotrophic activity (59.2 nmol g-1 h-1) and high diversity of methanotrophs was detected at FAV2, FAV1 was not active and appeared deprived of methanotrophs (1). Our aim was to investigate the main factors influencing methan…

Bridge over Troubled Water: Italy and the Black Mediterranean

2022

Since ancient times, Italy has served as a bridge between Africa and Europe, facilitating exchanges of goods, crops, legends, human beings, and deities. In recent decades, this role has come back to everyone’s attention because of the flows that have turned the Mediterranean into one of the main crossroads on the global migratory chessboard. Several young Africans have embarked the Mediterranean Passage. Some have arrived to the opposite shore, whereas some have not. The survivors have reshaped the history of the African Diaspora. The history of the Black Mediterranean resonates with that of the Black Atlantic. Moreover, the considerable presence of an African Italian community inevitably l…

Inequality of Spanish household expenditure for the 2006-2016 period- are we converging?

2019

The depth and persistence of the Great Recession that started in 2008 had a considerable impact on income distribution and inequality. Therefore, studies of living standards and evolution of income inequality are trend topics nowadays. Our goal was to estimate the impact of the economic crises on household expenditure and the trends and evolution of regional inequality. We applied our analysis to the Spanish case based on Household Budget Survey data from Instituto Nacional de Estadística (INE, the National Statistics Institute) and the period of eleven years between 2006 and 2016. A model that showed good results in modelling income was the biparametric gamma model, which is further very u…

Educació Intercultural i TIC: claus pedagògiques de la innovació i el canvi social en el segle XXI

2012

Aquest article planteja la necessitat d'oferir claus pedagògics de la innovació i canvi social a les universitats i institucions de formació del segle XXI. Per tant, el que subratlla és la importància de promoure l'educació intercultural a través de les TIC (tecnologies de la informació i comunicació) com a element d'innovació i projecció positiva de la diversitat cultural. Cooperació en xarxa des d'una perspectiva intercultural i la promoció d'habilitats Interculturals són elements fonamentals per a transformar una societat formació escenaris en permanent canvi social.

Strategy and business history rejoined : How and why strategic management concepts took over business history

2022

Scholars at the intersection of business history and strategic management have argued for the relevance and importance of historical methods in the study of strategic management of organizations. We flip this argument and ask about the role of strategic management concepts in the study of business history. We analyze volumes of Business History and Business History Review and a representative sample of business history books using a comprehensive set of keywords, each related to a specific sub-discourse in strategic management. Our results show that as scientific communities, business history and strategic management have become increasingly similar in their conceptual overlap. This study c…

“I Am Your Fan; Bookmarked!” Members’ Identification Development in Founder-Led Online Communities

2019

In this study, we present the findings from an inductive and interpretive case study of a founder-led online community (OC), exploring how members’ identification develops within the community over time. Using a longitudinal study of an OC that was founded by a reputable individual, it is shown that members were first attracted to the OC through their affective and cognitive identification with the founder; however, over time, they developed identification through social interaction with other members. The findings show that this transformation was enabled by the founder’s communication behavior, which not only led to inspired and engaged members but also to the emergence of new leaders who…

Impacts of anthropogenic factors on fish community structure in Lebialem-Mone Forest Landscape of Cameroon

2010

Two sites of the Cross River within the Lebialem-Mone forest landscape of Cameroon were chosen, one of the sites faced with human activities (test site) and the other with no human pressure (control site). The lengths and weights of fish obtained from both sites were analyzed in SPSS. Fish communities living within these 2 sites were compared after collecting fish from them using gill nets within 2 months of sampling (September-October 2009). Questionnaires were distributed to the fishers to respond to questions related to their fishing practices. Each fish from a sample of 240 fishes obtained from both sites was identified with its length and weight recorded. Fishing pressure constitutes t…
