THE DIASCIA FLOWER AND ITS BEE - AN OIL-BASED SYMBIOSIS IN SOUTHERN AFRICA
1984
As has been formerly shown, the double-spurred flowers of the South African genus Diascia (Scrophulariaceae) produce fatty oil as a primary attractant. Their oil-collecting pollinators have so far remained unknown. It is concluded from the morphology and from direct evidence of flower visitation that the recently established Melittid genus Rediviva represents the co-evolved pollinator group of these plants, at the same time demonstrating the presence of “manual” oil collectors in Southern Africa. The bees must introduce their especially equipped forelegs into the paired spurs of Diascia for harvesting the oil, thereby pollinating the flower. In the described case, a new species, Rediviva em…
“Facts Are Grasped by Us in Pictures (PT, 2.1). Remarks on Pictures and Facts in Wittgenstein’s Tractatus
2023
This paper proposes a (re)reading of the famous section in the Tractatus Logico-philosophicus, 2.1: “We picture facts to ourselves” and its relation to the similar section in the Prototractatus, 2.1: “Facts are grasped by us in images”. We reject the dominant solution that interprets the relation between facts and images as an isomorphic relation and propose that instead it is an internal relation: there are no facts that are not perceived through images. In other words: For us, linguistic animals, there is no world independent of language.

Sleep disturbances in Algelman syndrome: a questionnaire study
2004
Only few studies are available on sleep disorders in Angelman syndrome (AS), a neurodevelopmental disorder with several behavior disturbances. The aim of this study was to determine the prevalence of sleep disorders in a relatively large group of AS subjects, compared to that of age-matched controls. Fourty-nine consecutive parents of patients with AS (26 males and 23 females aged 2.3–26.2 years) were interviewed and filled out a comprehensive sleep questionnaire. Based on their genetic etiology, four groups were defined: deletion of chromosome 15q11–13 (25 subjects); methylation imprinting mutation (six subjects), UBE3A mutations (seven subjects) and paternal uniparental disomy (five subje…
I Vaticana fragmenta a due secoli dalla riscoperta
2022
Two centuries have passed since the palimpsest that transmits a Roman legal work known as the Vaticana fragmenta was rediscovered by Angelo Mai in the Vatican Apostolic Library in Rome. This paper reviews the main issues relating to this work and suggests some reasons why a new edition of the text is desirable. 1820 hat Angelo Mai in der Vatikanischen Apostolischen Bibliothek in Rom ein Palimpsest wiederentdeckt, welches ein römisches Rechtswerk – die so genannte Vaticana Fragmenta – überliefert. 200 Jahre sind seitdem genau vergangen. Dieser Beitrag gibt einen Überblick über die wichtigsten Aspekte dieses Werks und zeigt Gründe auf, warum eine neue Ausgabe dieses Textes wünschenswert ist.

«L’antico come principio di nuova architettura». Il tempo perenne delle opere e dei progetti
2022
Nonostante la raccolta degli scritti e dei progetti di Angelo Torricelli copra un arco temporale di oltre trent’anni (dal 1990 al 2021) essa costituisce una straordinaria narrazione coerente e coesa nella quale si ha chiara la sensazione di come l’oggetto della riflessione sia la connaturata dimensione sincronica dell’architettura tesa a essere, inevitabilmente, espressione di valori atemporali. Non a caso i titoli dei testi di Torricelli, ad iniziare da ciò che ne costituisce la sintesi suprema, l’espressione metonimica per eccellenza — "Il momento presente del passato" — tendono ad essere quasi dei voluti emblematici ossimori. Nella lettura interpretativa dell’antico in architettura propo…
Pyrano[2,3-e]isoindol-2-ones, new angelicin heteroanalogues
2009
A convenient synthesis of the pyrano[2,3-e]isoindol-2-one ring system, an heteroanalogue of angelicin, is reported. Our synthetic approach consists of the annelation of the pyran ring on the isoindole moiety using 5-dialkylamino- or 5-hydroxymethylene intermediates as building blocks. The photoantiproliferative activity of the new derivatives was studied. Some of them bearing the benzyl group at the 8 position were active with IC(50) in the micromolar range. Cell cytotoxicity involves apoptosis, alteration of cell cycle profile and membrane photodamage.
Jatkosodan retoriikka : argumentaatioanalyysi pääministeri Rangellin ja pääministeri Linkomiehen puheista
2009
Tutkimuksen tehtävänä on selvittää, millaista retoriikkaa Suomen jatkosodan aikaiset pääministerit JW Rangell sekä Edwin Linkomies puheissaan käyttivät. Tarkastelen tutkimuskysymystä analysoimalla kaksi puhetta, joista toisen puheen piti Rangell syksyllä 1941. Toinen on Linkomiehen kesällä 1944 pitämä puhe. Analysoin puheet erittäin tarkasti käyttämällä metodina valtio-opin alalla yleistä argumentaatioanalyysia. Pääasiallisena teoreetikkona käytän Chaim Perelmanin retoriikkatutkimusta ja tukena myös Aristoteleen Retoriikka-teosta sekä uudempaa retoriikka- ja sotaretoriikkatutkimusta. Aineistona työssä ovat puheet, jotka ovat kokonaisuudessaan myös gradussa mukana. Tutkimus osoittaa, että su…
