Tectono-stratigraphic evolution of a basin generated by transpression: the case of the Early Pliocene Lascari Basin (northern Sicily)
2011
Integrated stratigraphy and structural analysis carried out in the Madonie Mts. (Northern Sicily) is aimed to the description of a syn-sedimentary tectonic event, recorded in a small infra-pliocene basin restricted to the Lascari Syncline core. The onset and evolution of the basin was driven by transpressive tectonics, generating a lens-shaped, deep and narrow tectonic depression, bounded by steep and high, tectonically controlled slopes, also reflected in the present-day topography of the area. During the genesis of the basin, the tectonic control interferes with a dramatic sea level oscillation during the Messinian-Early Pliocene time interval. In this paper, the syn-tectonic deposits of …
New perspectives on the evolution of the genus Typhlatya (Crustacea, Decapoda): first record of a cavernicolous atyid in the Iberian Peninsula, Typhl…
1995
On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disru…
Patrones de selección de microalgas en comunidades de líquenes terrícolas en biocostras
2020
Las costras biológicas de los suelos (biocostras, CBS) están constituidas por una combinación de organismos, tanto fotoautótrofos como heterótrofos, que viven dentro o sobre la superficie de los suelos, los cuales, con sus interacciones y actividades, generan una capa conjunta con las partículas del sustrato. Los líquenes, debido a la complejidad de sus simbiosis son capaces de colonizar estos hábitats adversos para otros vegetales, gracias a sus adaptaciones ecofisiológicas. Las biocostras dominadas por líquenes son muy abundantes en los claros de los matorrales y pastizales que se desarrollan en los territorios yesíferos. Su diversidad, participación en los ciclos biogeoquímicos y potenci…
Examining Competing Entrepreneurial Concerns in a Social Question and Answer (SQA) Platform
2021
This study aims to determine the competing concerns of people interested in startup development and entrepreneurship by using topic modeling and sentiment analysis on a social question-and-answer (SQA) website. Understanding the underlying concerns of startup entrepreneurs is critical to society and economic growth. Therefore, greater scientific support for entrepreneurship remains necessary, including data mining from virtual social communities. In this study, an SQA platform was used to identify the sentiment of thirty concerns of people interested in startup entrepreneurship. Based on topic modeling and sentiment analysis of 18819 inquiries in various forums on an SQA, we identified addi…

Tietoturvan ylläpitämisen haasteet kotikontekstissa
2016
Tietoturva on tärkeä aihe, koska internetin käyttäjien määrä kasvaa yhä ja tietoturvauhat eivät ole vähenemässä. Päinvastoin, uusia uhkia havaitaan vuosittain tuhansia. Tietoturvan ylläpitämisessä tärkeä lenkki ohjelmistojen lisäksi on tietojärjestelmän käyttäjä itse. Paraskaan virustentorjunta ei välttämättä pelasta, jos käyttäjä lankeaa kalasteluhyökkäykseen. Tästä syystä tutkielmassa yritetään ymmärtää käyttäjiä, miten he toimivat ja miksi, jotta tietoturvaa voidaan parantaa ja kaikki voivat nauttia turvallisemmasta internetistä tulevaisuudessa. Tässä tutkielmassa huomataan, että iso osa käyttäjistä ei varaudu uhkiin erityisen hyvin ja monet suojakeinot jäävät käyttämättä. Lisäksi käyttä…

Littoral energy pathways in highly humic boreal lakes
2017
Littoral zones in lakes are among the most productive habitats in the world, but have been seriously understudied, as most limnological studies have concerned only pelagic habitats. The likely importance of littoral zones in clear lakes is widely acknowledged, but in contrast their role in dystrophic humic lakes has generally been assumed to be minor. In this thesis, littoral importance in whole-lake metabolism was studied in small and highly humic lakes in Southern Finland, where Lake Mekkojärvi was the principal study lake. Primary production (PP) measurements revealed that littoral periphyton, growing on surrounding aquatic vegetation, can dominate the whole-lake PP, and the highly autot…
Miksi Jyväskylän tieteellinen kirjasto perustettiin?
2012
Tieteellisen kirjaston perustaminen Jyväskylään oli osa tavoitetta perustaa suomalainen yliopisto suuriruhtinaskunnan pääkaupungin lisäksi myös maantieteellisesti keskeisemmälle paikalle. 1900-luvun alussa keskustelu yliopiston ja kirjaston merkityksestä heijasteli käynnissä olevaa yhteiskunnallista muutosta ja hanke koettiin paikallisuuden lisäksi myös kansallisen sivistystoiminnan kannalta ratkaisevaksi. Marja Kokko seuraa artikkelissaan Jyväskylän Tieteellisen kirjaston perustamisen vaiheita sekä aikalaiskeskustelua kirjaston merkityksestä suomalaisen akateemisen sivistyksen turvaajana. nonPeerReviewed
Social, health and rehabilitation sector educators’ competence in evidence-based practice : A cross-sectional study
2021
Aim: The purpose of the study was to identify and describe the characteristic profiles of evidence-based practice competence of educators in the social, health and rehabilitation sectors and to establish relevant background factors. Design: This study was carried out as a descriptive cross-sectional study. Methods: Data were collected from social, health and rehabilitation sector educators working in the 21 Finnish universities of applied sciences and seven vocational colleges (n = 422; N = 2,330). A self-assessment instrument measuring evidence-based practice competence was used. Competence profiles were formed using a K-cluster grouping analysis. Results: Three distinct competence profile…
