The Customer Experience Ecosystem in Two Cultural Contexts

Barari, Mojtaba ; Furrer, Olivier

In: Journal of Financial Services Marketing, 2018, vol. 23, p. 234-243

This study focuses on the development of a customer experience ecosystem during a journey which is embedded in meso- and macro-layers. Using the critical incident technique, the author collected in-depth interview data from bank customers in Switzerland and Iran to empirically study this ecosystem, including customer– company interaction in the micro-layer and social context of the...

Slow-targeted release of a ruthenium anticancer agent from vitamin B 12 functionalized marine diatom microalgae

Delasoie, Joachim ; Rossier, Jérémie ; Haeni, Laetitia ; Rothen-Rutishauser, Barbara ; Zobi, Fabio

In: Dalton Transactions, 2018, vol. 47, no. 48, p. 17221–17232

Herein we report the synthesis of a new biomaterial designed for targeted delivery of poorly water-soluble inorganic anticancer drugs, with a focus on colorectal cancer. Diatomaceous earth microparticles derived from marine microalgae were coated with vitamin B12 (cyanocobalamin) as a tumor targeting agent and loaded with the well- known anticancer agents cisplatin, 5-fluorouracil (5-FU), and...

In: Science Advances, 2020, vol. 6, no. 41, p. eabb8227

The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian...

Cold-water coral mound archive provides unique insights into intermediate water mass dynamics in the alboran sea during the last deglaciation

Fentimen, Robin ; Feenstra, Eline ; Rüggeberg, Andres ; Vennemann, Torsten ; Hajdas, Irka ; Adatte, Thierry ; Van Rooij, David ; Foubert, Anneleen

In: Frontiers in Marine Science, 2020, vol. 7, p. -

The Alboran Sea is widely recognized to host numerous cold-water coral ecosystems, including the East Melilla Coral Province. Yet, their development through time and response to climatic variability has still to be fully understood. Based on a combined investigation of benthic foraminiferal assemblages, foraminiferal stable isotope compositions, grain size analysis, sediment geochemistry, and...

Richness, phylogenetic diversity, and abundance all have positive effects on invader performance in an arid ecosystem

El‐Barougy, Reham ; Mac, Ivor, J. Scott ; Arnillas, Carlos A. ; Nada, Reham M. ; Khedr, Abdel‐Hamid A. ; Cadotte, Marc W.

In: Ecosphere, 2020, vol. 11, no. 2, p. -

In search of generalities in biological invasions, it is sometimes forgotten that invader success can be a function of both the diversity of the invaded community and the relatedness of the invader relative to community residents. Both qualities are likely to be especially important in stressful ecosystems, and identifying the species and community attributes that influence biological ...

Living (stained) foraminifera in the Lesser Syrtis (Tunisia): influence of pollution and substratum

El Kateb, Akram ; Beccari, Valentina ; Stainbank, Stephanie ; Spezzaferri, Silvia ; Coletti, Giovanni

In: PeerJ, 2020, p. e8839

Foraminifera are protozoans with biomineralized tests that can be successfully used as a low cost monitoring tool to assess the health status of marine environments. Living benthic foraminiferal assemblages can provide essential information on natural and/or anthropogenic stresses and provide baseline conditions for studies on fossil material. Several studies have highlighted the negative impact...

Foraminiferal-based biotic indices to assess the ecological quality status of the Gulf of Gabes (Tunisia): Present limitations and future perspectives

Kateb, Akram El ; Stalder, Claudio ; Martínez-Colón, Michael ; Mateu-Vicens, Guillem ; Francescangeli, Fabio ; Coletti, Giovanni ; Stainbank, Stephanie ; Spezzaferri, Silvia

In: Ecological Indicators, 2020, vol. 111, p. 105962

Biotic indices are tools to assess the ecological status of marine systems, and can be based on different metrics (such as ecological groups, specific diversity). The present study applies five biotic indices based on living (stained) benthic foraminiferal assemblages to assess ecological conditions in a wide area of the Mediterranean Sea in the heavily polluted Gulf of Gabes and along the...

Impact of bottom water currents on benthic foraminiferal assemblages in a cold-water coral environment: The Moira Mounds (NE Atlantic)

Fentimen, Robin ; Lim, Aaron ; Rüggeberg, Andres ; Wheeler, Andrew J. ; Rooij, David Van ; Foubert, Anneleen

In: Marine Micropaleontology, 2020, vol. 154, p. 101799

Strong bottom currents play a key role in cold-water coral environments by shaping their morphology and providing the necessary food for the corals to thrive. This study investigates the differences between living and dead benthic foraminiferal assemblages in such environments, more precisely on the Moira Mounds (NE Atlantic). A specific focus is to understand the role of currents and their...

Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago

Evers, Serjoscha W. ; Wings, Oliver

In: PeerJ, 2020, vol. 8, p. e8437

Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod dinosaurs, which we describe here for the first time. All of the theropod bones belong to relatively small individuals but represent a wide...
