Heikko ravintotilanne rajoittaa hauen (Esox lucius) ja kuhan (Sander lucioperca) kasvua Suotajärvessä
2014
Hauki ja kuha esiintyvät Suomessa usein samoissa vesistöissä, mutta niiden vuorovaikutuksesta tiedetään vain vähän. Mikäli lajit kilpailevat samoista resursseista, runsaat kuhaistutukset tai kuhan luonnollinen yleistyminen voivat vaikuttaa negatiivisesti hauen menestykseen. Tämän tutkimuksen tarkoitus oli selvittää hauen ja kuhan kasvua ja ravinnonkäyttöä Suotajärvessä. Kasvua tarkasteltiin myös suhteessa kasvukausien lämpötilaan. Ravinnonkäytössä keskityttiin hauen ja kuhan ravinnon päällekkäisyyteen ja siitä mahdollisesti seuraavaan ravintokilpailuun. Lisäksi verkkokoekalastuksilla selvitettiin järven kalaston yleistä tilaa, erityisesti ajatellen petokalojen ravintotilannetta. Hauki- ja k…
The Role of a Supportive Interpersonal Environment and Education-Related Goal Motivation During the Transition Beyond Upper Secondary Education
2018
This longitudinal study investigated the role of parents and peers as well as of education-related goal motivation during educational transitioning in late adolescence. The sample consisted of 1520 upper secondary education students attending either academic or vocational upper secondary school in Finland. They were surveyed three times: (1) in the first year of their upper secondary education, (2) in the second year of their upper secondary education, and (3) two years later. The results show, first, that when students in upper secondary education pursued their educational goals out of autonomous motivation they also invested more effort in their goals, which was reflected in high levels o…
Protection Motivation Theory in Information Systems Security Research
2021
Protection motivation theory (PMT) is one of the most commonly used theories to examine information security behaviors. Our systematic review of the application of PMT in information systems (IS) security and the comparison with its application for decades in psychology identified five categories of important issues that have not yet been examined in IS security research. Discussing these issues in terms of why they are relevant and important for IS security, and to what extent IS research has not considered them, offers new research opportunities associated with the study of PMT and IS security threats. We suggest how future studies can approach each of the open issues to provide a new roa…
The ethical culture of organisations and organisational innovativeness
2012
PurposeThe purpose of this paper is to examine the relationship between the ethical culture of organisations and organisational innovativeness.Design/methodology/approachA quantitative empirical analysis was conducted on the basis of a survey of 147 respondents within the public sector in Finland. A multivariate linear regression analysis was done to examine how the ethical culture of organisations is related to organisational innovativeness.FindingsA positive link was found in the ethical culture of an organisation and organisational innovativeness: ethical culture was important to behavioural, strategic and process innovativeness. Within the ethical culture of an organisation, the dimensi…

Istutuspäällikkö Gaddin julkiset matkaraportit 1763–1765
2022
Artikkelissa tarkastellaan Inrikes Tidningarissa julkaistuja raportteja Pehr Adrian Gaddin (1727–1797) matkoista Suomessa vuosina 1763–1765. Tekstit sekä rikastavat käsitystä Gaddin toiminnasta istutuspäällikkönä että antavat esimerkin mahdollisesta julkisuuden käytöstä vapaudenajan lopun Ruotsissa.

Äärellisten Borel-mittojen Fourier-muunnoksista euklidisissa avaruuksissa
2016
Tutkielmassa esitellään euklidisen avaruuden äärellisille Borel-mitoille Fourier-muunnokset kompleksiarvoisina kuvauksina ja tutkitaan niiden vähenemistä mentäessä ääarettömän kauas origosta. Keskeisenä kysymyksenä on, millä reunaehdoilla annetun kompkatikantajaisen ja äärellisen Borel-mitan Fourier muunnos vähenee polynomiaalisesti (eli sitä voidaan dominoida jollain euklidisen normin negatiivisella potenssilla) kaikkialla riittävän kaukana tai ainakin ”keskimääräisesti”. Mikäli tällainen Borel-mitta on absoluuttisesti jatkuva Lebesguen mitan suhteen kompaktikantajaisella ja sileällä tiheysfunktiolla, niin sen Fourier-muunnos vähenee aina polynomiaalisesti kaikkialla. Ongelmaa tarkastellaa…
The “Janus” Role of C/EBPs Family Members in Cancer Progression
2020
CCAAT/enhancer-binding proteins (C/EBPs) constitute a family of transcription factors composed of six members that are critical for normal cellular differentiation in a variety of tissues. They promote the expression of genes through interaction with their promoters. Moreover, they have a key role in regulating cellular proliferation through interaction with cell cycle proteins. C/EBPs are considered to be tumor suppressor factors due to their ability to arrest cell growth (contributing to the terminal differentiation of several cell types) and for their role in cellular response to DNA damage, nutrient deprivation, hypoxia, and genotoxic agents. However, C/EBPs can elicit completely opposi…
Sterol Regulatory Element-binding Protein-1c Is Responsible for Cholesterol Regulation of Ileal Bile Acid-binding Protein Gene in Vivo
2002
Ileal bile acid-binding protein (I-BABP) is a cytosolic protein that binds bile acid (BA) specifically. In the ileum, it is thought to be implied in their enterohepatic circulation. Because the fecal excretion of BA represents the main physiological way of elimination for cholesterol (CS), the I-BABP gene could have a major function in CS homeostasis. Therefore, the I-BABP gene expression might be controlled by CS. I-BABP mRNA levels were significatively increased when the human enterocyte-like CaCo-2 cells were CS-deprived and repressed when CS were added to the medium. A highly conserved sterol regularory element-like sequence (SRE) and a putative GC box were found in human I-BABP gene pr…
