A heuristic fuzzy algorithm for assessing and managing tourism sustainability
2019
“Smartness” and “sustainability” are gaining growing attention from both practitioners and policy makers. “Smartness” and “sustainability” assessments are of crucial importance for directing, in a systemic perspective, the decision-making process toward sustainability and smart growth objectives. Sustainability assessment is a major challenge due to the multidisciplinary aspects involved that make the evaluation process complex and hinder the effectiveness of available monitoring tools. To achieve the assessment objective, we introduce an enhanced fuzzy logic-based framework for handling the inherent uncertainty and vagueness of the involved variables: we apply our approach to Italy, and we…
Vicent Garcia, poeta europeu
2012
Després de repassar la bibliografia crítica i els textos poètics derivats, es procedeix a l’anàlisi d’un conegut sonet de Francesc Vicent Garcia, rector de Vallfogona (1578/1579-1623): «A una hermosa dama de cabell negre, que es pentinava en un terrat ab una pinta de marfil», que comença «Ab una pinta de marfil polia», en què l’autor mostra una habilitat poètica excepcional. S’insereix després el text en el seu context estètic i històric, el barroc europeu, i finalment se’l compara amb una sèrie de sonets equivalents, sobre el mateix motiu, produïts per autors castellans, portuguesos, italians i francesos. S’hi conclou que el de Garcia és molt original, tot i la forta codificació de la sèri…
Reversal of Gender Disparity in Journalism Education- Study of Ghana Institute of Journalism
2017
Journalism has practically become a feminine profession across the world. To understand the root of the flow of women into the Journalism profession it is pertinent to begin at the university education level. Gallagher’s 1992 worldwide survey of female students in 83 journalism institutions reveals a significant increase in number of female students. Djerf-Pierre (2007) and others argue along Bourdieu’s conception of education as a form of social capital which empowers, enables and enhances women’s competitiveness in a pre-dominantly androgynous social arena. The study analyses 16 years of enrolment data of the Academic Affairs Unit of the Ghana Institute of Journalism (GIJ), a leading Jour…
X-ray Single Crystal Structure, Tautomerism Aspect, DFT, NBO, and Hirshfeld Surface Analysis of a New Schiff Bases Based on 4-Amino-5-Indol-2-yl-1,2,…
2021
Four different new Schiff basses tethered indolyl-triazole-3-thione hybrid were designed and synthesized. X-ray single crystal structure, tautomerism, DFT, NBO and Hirshfeld analysis were explored. X-ray crystallographic investigations with the aid of Hirshfeld calculations were used to analyze the molecular packing of the studied systems. The H···H, H···C, S···H, Br···C, O···H, C···C and N···H interactions are the most important in the molecular packing of 3. In case of 4, the S···H, N···H, S···C and C···C contacts are the most significant. The results obtained from the DFT calculations indicated that the thione tautomer is energetically lower than the thiol one by 13.9545 and 13.7464 kcal…
The Quality of Life among Siblings of Autistic Individuals: A Scoping Review
2023
Autism spectrum disorders are a heterogeneous group of neurodevelopmental disorders presenting at a tender age, defined by qualitative deficits in social interactions and communication, thus having a substantial influence on the subject’s family unit. Quality of life (QoL) refers to a person’s perspective of their life situation, cultural and value background, objectives, expectations, and standards. When focusing on childhood and adolescence, age-related changes should be considered. For this scoping review, the authors used three peer-review literature database sources (PubMed/MEDLINE, Scopus, and ERIC) to delve deeper into components of the QoL of non-autistic siblings of autistic indivi…
Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid.
2012
Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related Amplified Fragment Length Polymorphism markers genetic variation and fitness to colonization history for all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex. Around 1970, D. incarnata suffered a severe bottleneck yet ultimately persisted and gradually spread throughout the spatially segregated dune slacks, aided…
Isolation By Distance (IBD) signals in the deep-water rose shrimp Parapenaeus longirostris (Lucas, 1846) (Decapoda, Panaeidae) in the Mediterranean S…
2013
Abstract The identification of boundaries of genetic demes is one of the major goals for fishery management, and few Mediterranean commercial species have not been studied from a genetic point of view yet. The deep-water rose shrimp Parapenaeus longirostris (Lucas, 1846) is one of the most important components of commercial landings in Mediterranean, its fishery aspects have received much attention, regrettably without any concern for the genetic architecture of its populations. The population structure in the central and eastern Mediterranean Sea (captures from six Italian and two Greek landings) has been analysed on the basis of surveys carried out with mitochondrial and AFLP markers. Dat…
Plant speciation in continental island floras as exemplified byNigellain the Aegean Archipelago
2008
Continental shelf island systems, created by rising sea levels, provide a premier setting for studying the effects of geographical isolation on non-adaptive radiation and allopatric speciation brought about by genetic drift. The Aegean Archipelago forms a highly fragmented complex of mostly continental shelf islands that have become disconnected from each other and the mainland in relatively recent geological times (ca<5.2 Ma). These ecologically fairly homogenous islands thus provide a suitable biogeographic context for assessing the relative influences of past range fragmentation, colonization, gene flow and drift on taxon diversification. Indeed, recent molecular biogeographic studies…
The origin of the serpentine endemic Minuartia laricifolia subsp. ophiolitica by vicariance and competitive exclusion.
2013
Serpentine soils harbour a unique flora that is rich in endemics. We examined the evolution of serpentine endemism in Minuartia laricifolia, which has two ecologically distinct subspecies with disjunct distributions: subsp. laricifolia on siliceous rocks in the western Alps and eastern Pyrenees and subsp. ophiolitica on serpentine in the northern Apennines. We analysed AFLPs and chloroplast sequences from 30 populations to examine their relationships and how their current distributions and ecologies were influenced by Quaternary climatic changes. Minuartia laricifolia was divided into four groups with a BAPS cluster analysis of the AFLP data, one group consisted only of subsp. ophiolitica, …
Missense variants in TAF1 and developmental phenotypes: Challenges of determining pathogenicity
2019
We recently described a new neurodevelopmental syndrome (TAF1/MRXS33 intellectual disability syndrome) (MIM# 300966) caused by pathogenic variants involving the X-linked gene TAF1, which participates in RNA polymerase II transcription. The initial study reported eleven families, and the syndrome was defined as presenting early in life with hypotonia, facial dysmorphia, and developmental delay that evolved into intellectual disability (ID) and/or autism spectrum disorder (ASD). We have now identified an additional 27 families through a genotype-first approach. Familial segregation analysis, clinical phenotyping, and bioinformatics were capitalized on to assess potential variant pathogenicity…
