Genetic diversity in theCentaurea cinerariagroup (Compositae) in Sicily using isozymes
2006
Abstract The genetic diversity of seven taxa endemic to Sicily, C. cineraria, C. busambarensis, C. ucriae subsp. ucriae, C. ucriae subsp. umbrosa, C. todari, C. erycina and C. saccensis, from 11 localities was investigated using isozymes. Eight loci from five enzyme systems (IDH, MDH, PGD, PGM and PGI) were examined. A total of 19 alleles were identified, some rare and two of them exclusive to different populations. The allelic frequencies and the genetic variability values for each population were calculated. On the whole, the genetic diversity, i.e., average polymorphism (P) = 0.41, average number of alleles per locus (A) = 1.75, Nei's gene diversity (H) = 0.18, is moderate, with the high…
Causes of Public Expenditure Inefficiency and Proposals for Their Streamlining
2020
The public sector has continually developed, as new needs of the population have been identified and the expectations of the population regarding the quantity and the quality of the provided services have already been rising. Unlike private management, the public administration has not always been concerned with the way results have been achieved, but, particularly with the results themselves, and, as long as these have been satisfying for the population, the resources employed for obtaining the results were of no much concern. The public administration monopoly in the provision of some services has led to the possibility of generating imbalances between the quality of the provided services…
A newCentaureaspecies (Asteraceae) from Mt Sakar, South-eastern Bulgaria
2013
A new species of Centaurea, C. sakarensis, known from a single locality north-east of the village of Lessovo on Mt Sakar, is described and illustrated. It belongs to C. sect. Acrolophus, and its morphologically closest relative is C. cariensis Boiss., a Turkish endemic from western and south-western Anatolia. The new species is currently known from a single population of about 1000 individuals, growing on open stony calcareous places, at 475 m a.s.l., and should be classified as Critically Endangered, (B1ab[i, ii, iii]+2ab [i, ii, iii]).
L’emigrazione dei laureati dalla Sicilia: le più recenti evidenze statistiche
2008
A taxonomic reassessment of the Centaurea busambarensis complex (Compositae, Cardueae), with description of a new species from the Egadi Islands (W S…
2017
The results of a statistical biometric study of the Centaurea busambarensis complex, which represents the C. cineraria aggregate in Sicily and its offshore islets, are presented. Seventeen populations, representing all seven previously recognized taxa (four species and three additional subspecies) plus a presumed undescribed one were studied. The statistical analysis (PCA and DA) of 26 morphological characters confirmed these eight taxa as distinct, geographically or ecologically vicarious units of equal weight, not supporting their treatment at different ranks. Consequently, they are recognized here as species, resulting in the description (with illustration) of one of them as new (C. aegu…
Effects of sulphonylureas on spontaneous motility and induced contractions in rat isolated uterus
1986
Abstract To clarify the action of sulphonylureas on calcium, the effect of tolbutamide and ghbenclamide has been investigated on a Ca-dependent process, the contractile activity of uterine smooth muscle. Both sulphonylureas antagonized the contractions evoked by CaCl2 in a non-competitive manner when the uterus was maintained in depolarizing solution and did not affect the spontaneous contractions of rat uterus. The capacity of tolbutamide and ghbenclamide to relax vanadate-induced contraction of rat uterus in Ca-free medium suggests that sulphonylureas may have an intracellular site of action related to cytosolic free Ca levels, or effect a reduction in Ca action.
"Ei se ole vaan laulua" : kuorolaisten kokemuksia Jyväskylän musiikkiluokkien A-kuoron ja Vox Aurean vaikutuksista
2017
Tutkimukseni tehtävänä on selvittää, miten Jyväskylän musiikkiluokkien A-kuorossa (sittemmin Vox Aurea) laulaneet ihmiset kokevat kuoron vaikuttaneen elämäänsä. Haastattelin tutkimukseeni viittä erilaisesta musiikillisesta taustasta tulevaa aikuista, jotka ovat laulaneet kuorossa sen alkuvuosina, sekä kuutta nuorta, jotka lauloivat kuorossa haastatteluhetkellä. Kahden eri sukupolven haastatteleminen mahdollistaa vertailun sen suhteen, ovatko kuorolaulun tärkeät ja vaikuttavat asiat huomattavasti muuttuneet kuoron alkuajoista nykypäivään. Haastattelu oli teemahaastattelu, jossa oli avoimen haastattelun piirteitä. Tutkimus on aineistolähtöinen ja aineistosta nousevan sosiaalisen näkökulman pa…
Sizilien: Eine Insel der Begegnungen der Kulturen
2017
Il contributo muove dalla constatazione del ruolo di culture, lingue e usi differenti in Sicilia nell'età di Federico II di Svevia, che, nel loro vicendevole fecondarsi hanno prodotto risultati di grande rilievo, per passare a illustrare gli esiti ugualmenet degni di nota, sia in ambito didattico che in ambito scientifico, del corso di laurea internazionale 'Glitema' (German literature in the European the Middle Ages), costituito da un consorzio universitario (Porto, Hub-University, Brema e Palermo, con la collaboarzione di docenti di altre numerose sedi.
Physiologizing (In)fertility in the Roman World: Lucretius on Sacrifice, Nature, and Generation
2016
The present paper reassesses the intellectual background of Lucretius’ treatment of infertility in 4.1233-1241, pointing out the author’s ability to combine genuine Epicurean doctrine and Roman cultural patterns. Lucretius’ denigration of religious mentality and his efforts to offer an entirely rational explanation of (in)fertility are interpreted in light of both internal evidence in the De Rerum Natura (e.g. 1.1-20; 248-264; 2.581- 660) and differents kinds of external evidence - including the so-called Laudatio Turiae, Rome’s fertility cults, and underused Epicurean sources such as PHerc 908/1390. Indeed, while systematically delegitimizing the traditional connection between supernatural…
Rilevazione nazionale in tema di formazione specifica di medicina generale in Italia
2017
Physicians have to get a “specific” diploma attending a threeyear training course provided by each regional health service in order to practice as General Practitioners in Italy. In the last years, there has been an ongoing debate about the need to evolve the specific regional courses into integrated specialization training courses, organized and managed by universities with the contribution of regional health services. The Italian Junior Doctors Association and the Giotto Movement carried out a national survey with the aim to identify strengths and weaknesses of the specific regional training courses. Three-hundred-two junior General Practitioners in training (61,2% females) answered to a …
