Una Mutazione Con B-Cromosomi, 2n = 14 + 3b, in Scilla Autumnalis L. (Liliaceae)
RIASSUNTOL'Autore ha esaminato cariologicamente numerose piante di Scilla autumnalis (Liliaceae) raccolte in Sicilia lungo la strada che da Siracusa porta a Floridia. Tali piante si rivelarono come biotipi regolarmente diploidi (2n = 14). Una pianta tuttavia risulto essere una mutazione cromosomica caratterizzata dalla presenza di tre B cromosomi, eucromatici e telocentrici cioe mostro il corredo diploide zigotico z = 2n = 14 + 3 B
Distribution and Frequency of B-Chromosomes in a Population of Urginea Fugax (Liliaceae) from Sardinia
SUMMARYDuring the investigation of the chromosome complements of a population of Urginea fugax from Sardinia, plants possessing 0–8 B-chromosomes were found. No plant with 7 B's has yet been found although the presence of such individuals can be inferred. All the plants were identified as Urginea fugax (Moris) Steinh. var. typica Lit. & Maire
Militari italiani e grande guerra
The essay deals with some aspects of migratory phoenomena which can be associated with the origin and endurance of the sense of ethnic and national identity. Beside the growing removal of the old mechanisms of language education, which remove the Italian language 'where originally owned' and cause its gradual and partly physiological replacement, we can see with Castillan in America, by integration, the decline of 'political Italian character' (i.e. 'Italianity' or Italian identity). A turning point before such process of Argentinian metamorphosis ('Argentinianization') finally established, was marked by the economic trends during World War 1. Its breaking out, in fact, coincided with the moment of utmost expansion (not only in Buenos Aires) of the foreign migratory 'particularly Italian' presence. Unlike what would later happen with World War 2, yet after nearly a twenty-year break in the incoming flow, between 1914 and 1918 we can see a tangible form of double patriotism or dual political-institutional loyalty from the migratory ethnic groups, within whom some choices arouse, such as the decision 'which many of their members made' to enlist under the 'old homeland's' flags to reach the European battlefields
Globalizzazione e criminologia: sfide e opportunità per una criminologia di oggi
Questo articolo esamina il fenomeno della globalizzazione e la concomitante crescita delle multinazionali in relazione all’impatto che esse hanno sulla struttura della società, sulla convivenza sociale, sulle crescenti divisioni di classe, sulla percezione e sull’applicazione, sovente compromessa, della giustizia distributiva, specialmente nel campo del lavoro, dell’impiego e dei diritti dei lavoratori. Vengono altresì analizzate le modalità in cui questa nuova realtà del mondo del commercio e del business crea delle serie conseguenze sulle relazioni umane, tra datori di lavoro e lavoratori, e persino tra organizzazioni internazionali e Stati.
L’autore evidenzia inoltre come questa nuova realtà abbia conseguenze che si riverberano non solo sulle forme già esistenti di criminalità, ma ne produca anche di nuove. Tali cambiamenti richiedono nuove prospettive di ricerca e d’innovazione nell’analisi e nella formulazione di teorie criminologiche adeguate al contesto della globalizzazione.
Cet article examine le phénomène de la mondialisation et la croissance concomitante des multinationales en référence à l'impact qu'ils ont sur la structure de la société; la cohésion social; les croissantes divisions de classe; la perception et l'application, souvent minimes, de la justice distributive, en particulier dans le domaine du travail, emploi et droits des travailleurs. Il propose une analyse de la façon dans laquelle cette nouvelle réalité et dynamique du monde du commerce et des affaires ont de graves conséquences sur les relations humaines entre les employeurs et les travailleurs, et même entre les Etats et les organisations internationales; comment ils donnent naissance à de nouvelles formes de criminalité ou aggravent les existantes; leur impact sur la criminologie et comme ils exigent un changement de perspective, des priorités de la recherche, et de l'innovation dans l'analyse et la formulation des théories de la criminalité dans le contexte de la mondialisation, qui pénètre tous les aspects de la vie politique, économique et social.
This article examines the phenomenon of globalization and the concomitant growth of multinationals in reference to the impact they have on the structure of society; social cohesion; the growing class divisions; the perception and application, often minimal, of distributive justice, especially in the field of labor, employment, and workers' rights. It offers an analysis of how this new reality and dynamics of the world of commerce and business have serious consequences on human relations between employers and workers, and even between states and international organizations; how they give rise to new forms of crime or aggravate existing ones; how they impact criminology and require a change of perspective, of priorities in research, and innovation in the analysis and formulation of theories of crime in the context of globalization, which penetrates all aspects of political, economic and social life
Grammatiche lessicalmente esaustive delle passioni Il caso dell'Io collerico. Le forme nominali
In base alle più comuni definizioni della parola passione, sembra delinearsi un quadro nel quale alcuni stati emotivi - alcuni relativamente stabili alcuni altri no - presentano fondamentalmente il carattere dell'eccesso e della sofferenza acuta. Delle passioni, più in particolare, sulla base della definizione del dizionario, appare dominante il carattere perturbante: la ragione, il giudizio, l'equilibrio, a loro contrapposti, sono condannati a subirne, a patirne, gli attacchi. L'universo del non-razionale, in tal senso, apparirebbe contraddistinto, non solo dall'assenza del logos, ma dalla presenza di slanci esplosivi volti alla negazione e alla distruzione di questo. Tra l'irrazionale, l'irragionevole e l'eccessivo costituirebbero una forza dirompente, difficilmente controllabile. Tali definizioni, in realtà, sembrano riprendere, semplificandola, la lunghissima e complessa tradizione che dall'epica omerica alle scienze cognitive contemporanee ha affrontato il tema delle passioni. Ad una di esse, quella primigenia dell'ira, è dedicato questo contributo di indagine lessico-sintattica.On the basis of most common definitions of the word passion, it seems to delineate a picture in which some emotional states present the character of excess and acute pain. According to dictionary definitions, perturbation is the dominant feature of passions: reason, sense, moderation are forced to suffer its attacks. The non-rational universe seems to be marked not only by the absence of logos but also by the presence of uncontrollable, disruptive explosive fits directed to the negation and destruction of logos. Dictionary definitions simplify the complex tradition that, from Homeric epics to Cognitive Sciences, has confronted the topic of passion. This paper is devoted to a lexical and syntactic analysis of one particular passion: ire
The fast response of academic spinoffs to unexpected societal and economic challenges. Lessons from the COVID‐19 pandemic crisis
The rapid emergence of the COVID‐19 crisis has challenged both private and public firms, requiring them to reshape their internal processes and external linkages in the fight against the virus, but also to survive the disrupting economic impact of the pandemic on their activities. Academic spinoffs have not been exempted from these dynamics. In this paper, we present and discuss a case study of an academic spinoff, Omnidermal, which has developed a new, efficient and easy‐to‐realize emergency life support machine for use in intensive and sub‐intensive care units. This case, apart from offering information on the best practices of how spinoffs may contribute socially to the fight against COVID‐19 and – more in general – against other exogenous shocks, also provides insights on their stages of development, evolution patterns and ability to define new solutions. The case shows that when the market needs are clear to a firm (as in the case of medical devices during the COVID‐19 crisis), the ‘legacy competences and practices’ of spinoffs (i.e., technical competences and work practices) can be fully exploited to compress the development time and to realize products demanded by the market. We also identify access to a network as being an essential boundary condition for this process. These results introduce an alternative scope for academic spinoffs. Given the ‘legacy competences and practices’ they are able to develop, they are ideal candidates to respond to the societal and economic challenges posed by a crisis over short periods of time. On the basis of these insights, we draw a series of implications for practitioners, policy makers and academics
A Case of Trisomy D1 — Syndrome of Patau
ABSTRACTA case of D1 trisomy is reported. The patient suffered of multiple congenital anomalies, which formed a characteristic pattern known as the « Patau's syndrome ».Chromosome analysis from blood cultures showed a modal number of 47; the additional chromosome was a 13 (D1).The aneuploidy origin and the probable mechanism, through which the malformations typical of Patau's syndrome might be produced, are discussed
