Segregation and co-occurrence of larval cestodes in freshwater fishes in the Bothnian Bay, Finland
1992
SUMMARYTwo autogenic (Triaenophorus crassus and T. nodulosus) and four allogenic (Diphyllobothrium latum, D. dendriticum, D. ditremum and Schistocephalus solidus) larval cestode species were found in 13 out of 31 fish species studied from the Bothnian Bay, NE Baltic. Gasterosteus aculeatus was the most heavily infected fish with 4 larval cestode species; for two of them (D. ditremum and S. solidus) the three-spined stickleback was found to be the required fish intermediate host. Among allogenic cestode species, those restricted to different definitive host species segregated their larval population in relation to the fish host, while, for example, D. ditremum and S. solidus, both maturing i…
Does population genetic structure support present management regulations of the northern shrimp (Pandalus borealis) in Skagerrak and the North Sea?
2014
AbstractPopulation structuring in the northern shrimp (Pandalus borealis) in the North Sea area (including Fladen and Skagerrak) was studied by microsatellite DNA analyses. Screening 20 sample locations in the open ocean and Skagerrak fjords for nine loci revealed low, but significant genetic heterogeneity. The spatial genetic structure among oceanic samples of Skagerrak and the eastern North Sea was weak and non-significant, consistent with the current management regime of one single stock. However, Skagerrak fjord samples generally displayed elevated levels of genetic differentiation, and significantly so in several pairwise comparisons with other fjords and oceanic samples. Although the …
Ensimmäisen luokan oppilaiden motoriset taidot ja reisilihasten aktiivisuus eri alustoilla käveltäessä
2016
TIIVISTELMÄ Heikkinen, A-E. 2016. Ensimmäisen luokan oppilaiden motoriset taidot ja reisilihasten aktiivisuus eri alustoilla käveltäessä. Liikuntakasvatuksen ja Liikuntabiologian laitos, Jyväskylän yliopisto, liikuntapedagogiikan sekä valmennus- ja testausopin kaksoisgradututkielma, 121s., 4 liitettä. Kävelyn oppiminen on tärkeä osa lapsen motorista kehitystä. Kävelytaito mahdollistaa lapsen osallistumisen monipuoliseen liikuntaan. Ympäristöllä, jossa lapsi liikkuu, on vaikutusta lapsen motorisen kehityksen etenemiseen. Motoristen taitojen ja fyysisen aktiivisuuden välillä on havaittu selvä, iän myötä vahvistuva yhteys. Kehittyvällä lapsella uusien motoristen taitojen opetteluvaiheessa liha…
De novo CCND2 mutations leading to stabilization of cyclin D2 cause megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome
2014
Activating mutations in genes encoding phosphatidylinositol 3-kinase (PI3K)-AKT pathway components cause megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome (MPPH, OMIM 603387)(1-3). Here we report that individuals with MPPH lacking upstream PI3K-AKT pathway mutations carry de novo mutations in CCND2 (encoding cyclin D2) that are clustered around a residue that can be phosphorylated by glycogen synthase kinase 313 (GSK-3 beta)(4). Mutant CCND2 was resistant to proteasomal degradation in vitro compared to wild-type CCND2. The PI3K-AKT pathway modulates GSK-3 beta activity(4), and cells from individuals with PIK3CA, PIK3R2 or AKT3 mutations showed similar CCND2 accumulation. CCND…
Mediated by the giants: Tracing practices, discourses, and mediators of platform isomorphism in a media organization
2022
News media are increasingly interwoven with social media platforms. Building on institutional theory, we trace the repercussions of the platform infrastructure inside a media organization by focusing on organizational discourses and practices in connection with the journalistic use of social media. The empirical material includes interviews, field notes, chat logs, and documents collected from a public service media organization during a 6-month on-site and virtual ethnography. The findings show how platform pressures intertwine with content production, audience representation, journalistic values, and organizational development, thus manifesting the infrastructuralization and institutional…
Sähköiset tunnistustyökalut lisäävät etäopiskelumahdollisuuksia
2019
TeSLA-hankkeen tavoitteena oli monipuolistaa ja parantaa verkko-opiskelumahdollisuuksia eurooppalaisissa korkeakouluissa kehittämällä työkaluja, jotka tunnistavat sekä etäopiskelijan että opintosuorituksen tekijyyden ja mahdollistavat monenlaisia luotettavia arviointi- ja palautteenantotapoja. Hankkeessa kehitetty sähköinen TeSLA-arviointijärjestelmä mahdollistaa opiskelijan tunnistamisen kasvojen, äänen ja näppäilyn perusteella sekä varmistaa suoritusten tekijyyden analysoimalla kirjoitustyyliä ja tunnistamalla plagioinnin. Kolmen laajan pilottikierroksen aikana seitsemässä eurooppalaisessa yliopistossa yhteensä noin 20 000 opiskelijan testaama TeSLA-järjestelmä lisää valmistuttuaan merkit…

Incorporating teacher-student dialogue into digital course material : Usage patterns and first experiences
2020
This work-in-progress research investigates teacher-student communication via Learning Management Systems (LMS) in highly populated courses. An LMS called TIM (The Interactive Material) includes a specific commenting technology that attempts to make teacher-student dialog effortless. The research goal is to explore students’ willingness to use the technology and identify patterns of usage. To these ends, a survey with both Likert and open-ended questions was issued to CS1 and CS2 students. A favorable student evaluation was observed while several critical viewpoints that inform technology development were revealed. We noticed that besides appreciating the possibility of making comments, man…
Cueva de El Toro (Antequera, Malaga-Spain): a Neolithic stockbreeding community in the Andalusian region, between the 6th and 3th millennia BC
2004
The occupation evidence shown by the cave El Toro, is that of a unique stockbreeding community in the Andalusian region. The calibrated dates for this occupation period go from the second quarter of the sixth millennium up to the second millennium BP. There is also evidence of occasional occupation throughout later millennia up to the Hispano-Muslim period. The nature of thisoccupation is determined by the close link between the cave and the community which occupied it, both continuously and periodically. Throughout the occupation levels, the community's skillful control of technical processesand its remarkable knowledge on how to transform local primary resources, have shown that this comm…
On the occurrence of the silverstripe blaasop Lagocephalus sceleratus (Gmelin, 1789) along the Libyan coast
2012
Five individuals of Lagocephalus sceleratus were caught by trammel and gill nets off Ain Al Ghazala, Libya (approximately 32°09'N − 23°15'E) between 15 and 25 m depth in September 2010. Our findings represent the first record of this toxic species from Libya and provide further evidence of its occurrence along North African coasts.
