Ecological and genetic factors contributing to invasion success : the northern spread of the Colorado potato beetle (Leptinotarsa decemlineata)
2008
Sanna Boman tutki väitöskirjassaan koloradonkuoriaisen potentiaalia levitä Suomeen. Hän selvitti kuoriaisten mahdollisuuksia selviytyä alhaisissa lämpötiloissa ja kykyä sopeutua Suomen viileään ilmastoon.Boman havaitsi, että koloradonkuoriaisella on potentiaalia levitä Suomeen pysyvästi, sillä geneettiset tekijät ja Suomen kesälämpötilat eivät rajoita koloradonkuoriaisen selviytymistä pohjoisessa.Koloradonkuoriaisilla on geneettistä vaihtelua elinkiertopiirteissä, kuten kehitysajassa ja koossa, minkä avulla kuoriaiset voivat sopeutua entistä paremmin uusiin olosuhteisiin, esimerkiksi alhaiseen lämpötilaan. Koloradonkuoriaiset pystyvät kehittymään ja selviytymään Suomen normaaleissa kesäolos…
Los estilos de liderazgo de la Policía Local de la Comunidad Valenciana: Una aproximación desde la Teoría del Liderazgo Transformacional
2012
Tomando como base la Teoría de Liderazgo Transformacional (Bass, 1985), se estudian las conductas que componen los estilos de liderazgo y su relación con tres variables de resultado: la eficacia del líder, la satisfacción con el líder y el esfuerzo extra de los subordinados; así como el aumento de los efectos (augmentation effect) del liderazgo transaccional cuando además se utiliza el liderazgo transformacional. La muestra es representativa del universo de policías locales de la Comunidad Valenciana (España) y está compuesta por 975 policías locales (828 hombres y 147 mujeres) pertenecientes a las plantillas de 42 localidades y que son dirigidos por 42 jefes. Los resultados muestran jefes …
Preparation of Biomolecule Microstructures and Microarrays by Thiol-ene Photoimmobilization
2009
A mild, fast and flexible method for photoimmobilization of biomolecules based on the light-initiated thiol-ene reaction has been developed. After investigation and optimization of various surface materials, surface chemistries and reaction parameters, microstructures and microarrays of biotin, oligonucleotides, peptides, and MUC1 tandem repeat glycopeptides were prepared with this photoimmobilization method. Furthermore, MUC1 tandem repeat glycopeptide microarrays were successfully used to probe antibodies in mouse serum obtained from vaccinated mice. Dimensions of biomolecule microstructures were shown to be freely controllable through photolithographic techniques, and features down to 5 …
Spatio-Chromatic Adaptation via Higher-Order Canonical Correlation Analysis of Natural Images
2014
Independent component and canonical correlation analysis are two general-purpose statistical methods with wide applicability. In neuroscience, independent component analysis of chromatic natural images explains the spatio-chromatic structure of primary cortical receptive fields in terms of properties of the visual environment. Canonical correlation analysis explains similarly chromatic adaptation to different illuminations. But, as we show in this paper, neither of the two methods generalizes well to explain both spatio-chromatic processing and adaptation at the same time. We propose a statistical method which combines the desirable properties of independent component and canonical correlat…
A new solution for the sea wave exploitation. A linear ironless generator
2019
The exploitation of sea wave represents an important frontier for the energy sustainability in the next future. Despite the proposal of several techniques and solutions, commercial devices are not available. In this context, the Department of Engineering is investigating an innovative solution based on linear energy generators. This machine can be adopted as the main component in a wave energy converter, that is the device for the energy extraction of sea wave. Starting from an existing prototype, the paper examines the replacement of the iron stator with a non-magnetic material, in order to solve several common problems of linear generators, such as the cogging force. Results are reported,…
Subglacial bedforms of the Zemgale Ice Lobe, south-eastern Baltic
2015
Abstract Presented in this paper are the results of the mapping of ∼6600 subglacial bedforms of the Zemgale Ice Lobe (ZIL), their composition and internal structure in the south-eastern Baltic region. Topographic maps at scale 1:10,000 were mainly used to map bedforms in Latvia, while a digital elevation model with cell size of 5 m was used for North Central Lithuania. The ZIL operated during the deglaciation of the Late Weichselian Scandinavian Ice Sheet (SIS), at least in the Middle Lithuanian and North Lithuanian glacial phases, and created a subglacial landform assemblage consisting of glacial lineations such as drumlins, mega-flutings, Mega Scale Glacial Lineations (MSGLs) and transver…
"Lavorare" il dato linguistico: prospettive e limiti. Alcune considerazioni dall'esperienza dell'Atlante Linguistico della Sicilia (ALS)
2018
The present work focuses on the relationship between linguistic research and the use of new technologies for linguistic data processing and analysis. Starting from the experience of the Atlante Linguistico della Sicilia (ALS), this paper describes a XML schema, based on the theory of trasferenza (transference) by Regis (2013), for the annotation and analysis of the data from the onomasiological questions of the ALS sociovariational questionnaire. Moreover, this modest case study tries to make clear the pros and cons of technological devices in linguistic research.
Critical Digital Editions of Theatrical Texts: The Example of La estrella de Sevilla
2014
This article analyses the process of creating a multilingual and multimedia critical digital edition of the text from the Spanish Golden Age La Estrella de Sevilla. It begins with a reflection on what a critical digital edition is, and then it presents different projects about digital editions of theatrical texts as well as some practical issues on the encoding of the texts included in this digital critical edition.
Levelling Of I-Umlaut in Classical and Post-Classical Old Frisian Nouns
2022
The paper discusses and evaluates the extent of i-umlaut levelling in classical (ca. 1300–1400) and post-classical (ca.1400–1550) Old Frisian nouns. In terms of the methodology, the main goal of the analysis is to identify the quantitative relation between the incidence of i-umlauted and umlautless root vowels in the nominal declension paradigms. In order to understand and assess the process of levelling of i-umlaut in Old Frisian, three aspects that may have had an impact on the presence or absence of i-mutated vowels are taken into account, namely: the presence of the i-mutation trigger *-ī and *-j and *-i, the establishment of whether i-mutation is noticeable in the entire paradigm or it…
Association of ADHD with genetic variants in the 5'-region of the dopamine transporter gene: evidence for allelic heterogeneity.
2008
Contains fulltext : 69953.pdf (Publisher’s version ) (Closed access) Multiple studies have reported an association between attention deficit hyperactivity disorder (ADHD) and the 10-repeat allele of a variable number tandem repeat (VNTR) polymorphism in the 3'-untranslated region (3'UTR) of the dopamine transporter gene (DAT1). Yet, recent meta-analyses of available data find little or no evidence for this association; although there is strong evidence for heterogeneity between datasets. This pattern of findings could arise for several reasons including the presence of relatively rare risk alleles on common haplotype backgrounds or the functional interaction of two or more loci within the g…
