Understanding the crowdfunding phenomenon and its implications for sustainability

2019

Abstract Nonetheless the large body of knowledge rapidly accumulated on crowdfunding as well as the growing relevance of this phenomenon for sustainability, there are very few studies on the role of crowdfunding for sustainability-oriented projects, and many related issues are still far from being fully understood. This signalises a clear need for unveiling the main dynamics of the relationship between crowdfunding and sustainability, and also opening up useful directions for future research on this relationship. To conceptualize the implications of crowdfunding for sustainability, we propose and use a framework, encompassing five dimensions, namely the project creator, the backers, the cam…

A scoping review on interventions to promote physical activity among adults with disabilities

2016

People with disabilities are at increased risk for obesity as well as other secondary conditions that lead to further decline in health and functional status. Despite there being strong evidence that physical activity (PA) can help to reduce the incidence and severity of preventable conditions, approximately half of all adults with disabilities get no regular physical activity. In addition, there is limited knowledge on the PA promotion interventions effectiveness among individuals with disabilities. Recently the Behaviour Change Techniques Taxonomy version 1 (BCT Taxonomy v1) became available as a method for reporting, replicating, and synthesizing research evidence, yet it is lacking in s…

A multi-locus inference of the evolutionary diversification of extant flamingos (Phoenicopteridae).

2014

9 pages; International audience; BACKGROUND: Modern flamingos (Phoenicopteridae) occupy a highly specialized ecology unique among birds and represent a potentially powerful model system for informing the mechanisms by which a lineage of birds adapts and radiates. However, despite a rich fossil record and well-studied feeding morphology, molecular investigations of the evolutionary progression among modern flamingos have been limited. Here, using three mitochondrial (mtDNA) markers, we present the first DNA sequence-based study of population genetic variation in the widely distributed Chilean Flamingo and, using two mtDNA and 10 nuclear (nDNA) markers, recover the species tree and divergence…

Chemoecological study of the invasive alga Caulerpa taxifolia var. distichophylla from the Sicilian coast

2022

Marine invasive species and their bioactive metabolites have become critical ecological issues in the Mediterranean Sea. In particular, the highly invasive green algae Caulerpa taxifolia and Caulerpa cylindracea are known to contain the bioactive sesquiterpene caulerpenyne (1) and the bisindolic alkaloid caulerpin (2), potentially acting as chemical stressors for native species. The recent spread of a variety of C. taxifolia, Caulerpa taxifolia var. distichophylla, also raises urgent questions about its chemical composition. Indeed, the only chemical data available for this alga are limited to the seasonal variations of caulerpenyne (1) in samples collected in the Eastern Mediterranean. In …

Studies on the genus Capparis L. (Capparaceae) in Lao PDR. VI: a new species from the Bolikhamxai Province

2022

A new species of Capparis, C. phatadke, is described and illustrated from the Bolikhamxai Province, central Lao PDR. The new species is characterized by lianous habit, brown-reddish indumentum, straight stipular thorns, laminar bracts, large flowers arranged in terminal corymbs or subumbels, long filaments and large ovary. It is so far known from a single locality, where has been observed in mixed deciduous forest and secondary forest in a limestone area. Its ecology and phenology are discussed, and its conservation status is assessed.

Preliminary analysis of osteocyte lacunar density in long bones of tetrapods: all measures are bigger in sauropod dinosaurs.

2013

Osteocytes harbour much potential for paleobiological studies. Synchrotron radiation and spectroscopic analyses are providing fascinating data on osteocyte density, size and orientation in fossil taxa. However, such studies may be costly and time consuming. Here we describe an uncomplicated and inexpensive method to measure osteocyte lacunar densities in bone thin sections. We report on cell lacunar densities in the long bones of various extant and extinct tetrapods, with a focus on sauropodomorph dinosaurs, and how lacunar densities can help us understand bone formation rates in the iconic sauropod dinosaurs. Ordinary least square and phylogenetic generalized least square regressions sugge…

Il contributo dell'Orto Botanico di Palermo allo studio tassonomico delle flore tropicali

1990

The Palermo Botanical Garden contained, since its foundation, rich collections of tropical and subtropical plants. In the past various botanists like A. Todaro, A. Borzì, G.E. Mattei, D. Lanza, V. Riccobono, A. Terracciano, carried out studies on entities growing in the Garden, describing several new taxa. Taxonomical and phytogeographical researches on the flora of the Horn of Africa have been recently undertaken.

Typification of names inDrabasect.Aizopsis(Cruciferae, Arabideae) based on material from Italy

2013

Names of 20 presumed taxa in Draba sect. Aizopsis, all based on material from Italy, are considered. Full synonymies are provided, and types are designated (for 14 names) or indicated. Most of the taxa are currently considered unworthy of recognition, of which 16 belong to D. aspera sensu lato. However, the question of whether the Sicilian populations might be distinct from the peninsular populations is still unsettled.
