First records of Lethocerus cfr. patruelis (Stål, 1854) from Calabria (southern Italy) (Hemiptera: Heteroptera, Belostomatidae)
Get PDFLethocerus patruelis (Stål, 1854) is the only European member of the Belostomatidae family. During the last decades Lethocerus patruelis records have become frequent in south-eastern Italy, probably due to multiple accidental introductions or a natural westward spread of its range. The first records of Lethocerus cfr. patruelis for the Calabria region are here reported. The first individual was observed alive and photographed in Villapiana (Cosenza province), while the second one was found and collected in Prunella (Melito di Porto Salvo municipality, Reggio Calabria province). The status of Lethocerus patruelis in this region and in Italy as introduced or naturally spreading species is yet to be assessed
The Odonate fauna of Val Grande National Park (Insecta: Odonata)
Get PDFThe results of a survey aimed at describing the Odonate fauna of Val Grande National Park are presented, which was carried out in the framework of the project “Animal Biodiversity Monitoring in Alpine Habitat”. Relevant literature was examined and data collected in- tensively in summer 2016 and extensively in the period 2014-2019. Prior to this research specific knowledge on dragonfly and damselfly presence and distribution accounted for 6 species for the study area, which were recorded near the northern border but outside the park. The first Odonate checklist here provided is based on 188 records (1173 individuals), of which 137 are recent and unpublished. Compre- hensively 25 species were recorded (14 breeding), which represent 26% of the Italian fauna, 36% of Piedmont and 58% of the province of Verbano Cusio Ossola, whereas three species were not confirmed; 10 species were found inside the park (4 breeding). Odonate diversity was remarkable, thanks to Val Grande geographical position between the Alps and the Insubric region and to high rainfall coupled with a complex orography. The study area hosts populations of the boreo-alpine species Somatochlora alpestris and Sympetrum danae, which are scattered and isolated in Italian Alps, and of the endemic European Cordulegaster bidentata; it hosts lotic taxa which are concentrat- ed in SW Europe where they are under pressure because of droughts and exploitation of freshwater. Conservation and status issues of observed dragonflies and damselflies are discussed in the light of the growing interest gained by odonates as ecological indicators. The study proposes to use this knowledge to guide the future expansions of the protected area
The bee genus Pseudoanthidium: revision of the subgenus Exanthidium with the description of a new species (Apoidea: Megachilidae)
Get PDFExanthidium Pasteels, 1969 is today recognised as a subgenus of the genus Pseudoanthidium which comprises a small number of little-known species distributed between the Atlantic coast and Central Asia. The taxonomic status is reviewed and the members of the subgenus are here presented for the first time with photographs and line drawings illustrating the specific distinguishing characters. An identification key and distribution maps are given. A new species, Pseudoanthidium (Exanthidium) deserticolum sp. n. is described from Saudi Arabia. It is close to P. (E.) wahrmanicum which is found in the southern Levant and the Algerian Sahara
Digital technologies for the tourism development of the “weak” mountain. Opportunities and limits
No full textThe aim of the paper is to discuss the opportunities and limitations of the digital technologies for tourism promotion and development in the declining areas of Italian mountains, adopting the methodological perspective of learning tourism. This is a form of participatory tourism where host communities and tourists play a co-pro-tagonist role in planning the offer of a place, considering the value given to local re-sources
From 1854 cholera to Covid-19
No full textJohn Snow’s method of limiting contagion and death in the 1854 cholera epidemic is one of the foundations of modern epidemiology: a fine example of how data, statistical information and knowledge can make an essential contribution. Yet today, in the course of the COVID-19 pandemic, what Snow did cannot be done. I refer to the Italian case (although some points can be easily generalised) to identify some obstacles and propose possible solutions: we do not know where the infected live and where they have become infected; we do not know their demographic and socio-eco-nomic characteristics; we do not have sufficient information on mobility; we do not make full use of the conceptual tools we have; the principle of privacy overrides the principle of public health. In the conclusions, I offer an example of what could be done if these obstacles were removed. In particular, I refer to a recent paper to illustrate the contribution that statistics and mathematical models could make to inform public opin-ion and to provide authorities with suggestions for more effective and equitable pan-demic policies
Alea and microtakaful insurance
No full textAn essential component of the insurance contract is the alea, because the insurance world has been structured precisely to address the risk in its different realities. The alea assuming some economic-financial connotations is managed differently according to the cultures to which it refers. The note shows that in the Islamic world insurance dynamics have their own characteristics that are highlighted in the different takaful contracts and in the different organizational models taken into consideration and how the concept of mutuality that has a strong ethical vocation is catching the attention of customers Muslims

Get PDFFrom Pluralism to a Monochrome Society? How School Historical Education was Shaped in Putin’s Russia
Get PDFLa svolta politica russa all’inizio degli anni 2000 comportò una trasformazione nell’insegnamento della storia. Si è trattato di un processo graduale che dai tentativi di contenere “l’eccessivo pluralismo” ha portato al tentativo di introdurre un manuale di storia unico. È stato istituito il controllo dei contenuti del manuale attraverso il curricolo (standard) federale di storia. Il richiamo ad un maggiore “sano” patriottismo ha condotto alla comparsa di manuali sciovinisti e revanscisti, propensi alla riabilitazione di Stalin. Essi sono stati oggetto di critiche acerrime sia da parte dei docenti democratici sia da parte degli attivisti nel campo dei diritti umani. Benché un’impostazione patriottica della storia avesse ottenuto il consenso di alcuni storici ed educatori, l’idea di un unico manuale si dimostrò impraticabile. I nuovi libri di testo della fine della prima decade del 2000 avevano un tono moderato e dimostravano che i loro autori non avevano tenuto conto di alcuni requisiti che il governo pretendeva di imporre. Così, nonostante un considerevole investimento statale volto a promuovere, attraverso l’insegnamento della storia, un’educazione patriottica e fedele al regime, gli sforzi degli ideologi pro-Cremlino non produssero gli effetti desiderati
La decolonizzazione nei manuali di storia italiani per le scuole secondarie di secondo grado: 1990-2020
Get PDFLa presente ricerca indaga il modo in cui vengono presentati i temi legati alla decolonizzazione nei manuali scolastici italiani rivolti all’ultimo anno delle scuole secondarie superiori, focalizzando l’attenzione su due questioni principali: i fattori alla base dell’avvio del processo di decolonizzazione e la situazione politica ed economica nelle ex-colonie all’indomani dell’indipendenza. L’indagine si sofferma, in particolare, sulla presenza e rilevanza dei movimenti indipendentisti nella narrazione del processo di decolonizzazione. Attraverso questi elementi è possibile osservare in che misura e in quale modo le società extra-europee vengono rappresentate nel quadro del racconto storico. La ricerca si conclude mettendo in luce alcuni aspetti del contesto storiografico italiano alla luce dei risultati dell’indagine sui manuali
