Luokittelumenetelmän evaluointimenetelmien vertailu pienten aineistojen tapauksessa simulointikokein

2016

Luokitteluanalyysin tyypillinen ongelma on mallin valinta ja/tai muuttujien eli piirteiden valinta. Tavoitteena on estimoida luotettavasti luokitteluvirheen todennäköisyys opetusaineiston avulla - ideaalissa tilanteessa käyttäen riippumatonta testiaineistoa. Tällöin saadaan estimaatti yleistämisvirheelle, joka kuvaa opetusaineistosta estimoidun mallin kykyä ennustaa riippumatonta testiaineistoa. Usein kuitenkin aineiston niukkuudesta johtuen ei voida käyttää erillistä riippumatonta testiaineistoa, jolloin ei myöskään voida estimoida suoraan yleistämisvirhettä. Tällöin voidaan kuitenkin käyttää otoksen uudelleenkäyttömenetelmiä, joista käytetyimmät lienevät ristiinvalidointi ja bootstrap. Me…

Charles XIV Jean (alias Jean-Baptiste Bernadotte) and the Finnish Question

2008

One of the first important acts of Charles Jean XIV as head of Sweden was to renounce the idea of reconquering Finland. It was a difficult position to take, considering the conditions of the time, and in all likelihood, he swung back and forth for several months before taking a definitive decision, contrary to what he might have asserted later. Moreover, the regent, then sovereign, of Sweden, was forced to justify his choice throughout his reign and to navigate between the dangerous reefs of a diverse opposition , which was organised to varying degrees.Thus, the Finnish policy was, for another thirty years, a thorn in the side of the royal power at Stockholm.

Inhibition of the pro-inflammatory mediators' production and anti-inflammatory effect of the iridoid scrovalentinoside.

2007

We have studied scrovalentinoside, an iridoid with anti-inflammatory properties isolated from Scrophularia auriculata ssp. pseudoauriculata, as an anti-inflammatory agent in different experimental models of delayed-type hypersensitivity. We found that scrovalentinoside reduced the edema induced by oxazolone at 0.5 mg/ear and sheep red blood cells at 10 mg/kg. The observed effect occurred during the last phase or inflammatory response; during the earlier phase or induction of the delayed-type hypersensitivity reaction, no significant activity was noted. Thus, scrovalentinoside reduced both the edema and cell infiltration in vivo and reduced lymphocyte proliferation in vitro, affecting the cy…

Anti-inflammatory glycoterpenoids from Scrophularia auriculata.

2000

The activity of the four glycoterpenoids: two saponins, verbascosaponin A and verbascosaponin, and two iridoids, scropolioside A and scrovalentinoside, isolated from Scrophularia auriculata ssp. pseudoauriculata, were studied in different models of acute and chronic inflammation. Both saponins significantly inhibited the mouse paw edema induced by carrageenan and ear edema induced by single and multiple doses of 12-O-tetradecanoylphorbol 13-acetate (TPA). Verbascosaponin A showed a potency twice as high as that of indomethacin in the acute TPA model. Verbascosaponin A and scropolioside A were active after a long latency period against ethyl phenylpropiolate edema, as are glucocorticoids. Wh…

First records of pollinators of two co-occurring Mediterranean Apocynaceae

2011

This article presents results of a field survey of pollinators of two Apocynaceae, Periploca laevigata subsp. angustifolia (Labill.)Markgraf (Periplocoideae) and Caralluma europaea (Guss.) N.E.Br. Asclepiadoideae) co-occurring on Lampedusa Island, Mediterranean sea. Fifteen species within nine families of Diptera have been identified as pollinators of the two plants. The families involved are Tephritidae, Milichiidae, Trixoscelididae, cathophagidae, Anthomyiidae, Muscidae, Calliphoridae, Sarcophagidae, Rhinophoridae. Families of Muscidae and Sarcophagidae are the more represented, respectively with four and three species. P. laevigata subsp. angustifolia seems to have a broader spectrum of …

Sostenibilità fra preesistenze storiche e città contemporanea

2010

The ZEN district in Palermo, Sicily, is a proving ground for the experimentation of sustainability of architecture in outskirts. In the historical city centre, the consistency of the used materials ensures a long duration of the buildings, as well as an efficient protection of the internal spaces. A for centuries consolidated urban structure configures an environment, which the inhabitants recognize as appropriate to their living. That is generally different to the outskirt this project is about. The project of residencies between ZEN 2 and Cortile Gnazziddi hypothesizes a consolidation of an existing city by adding a new building. Therewith shall be filled a crack due to interventions of d…
