Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range

2021

Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica 41: 50–88. The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified, of which 87% are above the treeline. The lakes hosting L. arcticus decrease in altitude from south to north, which results from its temperature preferences. The majority of the locations are at a lower lake air t…

Tuottaako pohjoismainen malli hyvää työelämän laatua vielä tulevaisuudessakin?

2017

Pohjoismaat ovat perinteisesti erottuneet työelämän laatuvertailuissa Euroopan ykkösinä. Taustalla vaikuttavat työmarkkinoiden palveluvaltaisuus ja korkea työvoiman osaamistaso, mutta myös erilaiset institutionaaliset tekijät, kuten työmarkkinoiden sääntely, ammattiyhdistysliikkeen asema ja sosiaalipoliittiset ratkaisut. Työelämän laatu voi kuitenkin heikentyä, kun näitä ankkureita kierretään tai kun ne eivät tavoita kaikkien alojen työntekijöitä. Organisaatioiden uudelleenjärjestelyt, ulkoistaminen ja alihankinta sekä uusien alojen ja työnteon uusien muotojen syntyminen saattavat heikentää työelämän laatua. nonPeerReviewed

Organocatalytic Enantioselective Vinylogous Henry Reaction of 3,5-Dimethyl-4-nitroisoxazole with Trifluoromethyl Ketones

2017

The enantioselective vinylogous Henry reaction of 3,5-dimethyl-4-nitroisoxazole with trifluoromethyl ketones employing a bifunctional squaramide organocatalyst has been developed. A series of isoxazole bearing trifluoromethyl-substituted tertiary alcohols, 2-substituted (R)-1,1,1-trifluoro-3-(3-methyl-4-nitroisoxazol-5-yl)propan-2-ols, were obtained under these mild reaction conditions in good yields and moderate to good enantioselectivities

Optimization of trigeneration systems by Mathematical Programming: influence of plant scheme and boundary conditions

2014

The large potential for energy saving by cogeneration and trigeneration in the building sector is scarcely exploited due to a number of obstacles in making the investment attractive. The analyst often encounters difficulties in identifying optimal design and operation strategies, since a number of factors, either endogenous (i.e. related with the energy load profiles) and exogenous (i.e. related with external conditions like energy prices and support mechanisms), influence the economic viability. In this paper a decision tool is presented, that simultaneously optimizes the plant lay-out, the sizes of the main components and their operation strategy. For a specific building in the hotel sect…

Positive solutions for nonlinear Robin problems

2017

We consider a parametric Robin problem driven by the p-Laplacian with an indefinite potential and with a superlinear reaction term which does not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions. We prove a bifurcation-type theorem describing the nonexistence, existence and multiplicity of positive solutions as the parameter varies. We also show the existence of a minimal positive solution $\tilde{u}_\lambda$ and establish the monotonicity and continuity of the map $\lambda\to \tilde{u}_\lambda$.

Lapsiperheiden hyvinvointi koronapandemian aikana: Osaraportti 2: Noin viisivuotiaiden hoito- ja varhaiskasvatusjärjestelyt

2021

Tämä osaraportti esittelee Jyväskylän yliopiston yhteistyössä Terveyden ja hyvinvoinnin laitoksen (THL) kanssa toteuttaman Varhaiskasvatus ja koronapandemia -hankkeen kyselytutkimuksen perusteella noin viisivuotiaiden lasten hoito- ja varhaiskasvatusjärjestelyitä vuoden 2020 aikana. Hanketta rahoittaa Jyväskylän yliopiston osalta Opetus ja kulttuuriministeriö. THL:n osalta rahoitus perustuu lisämäärärahaan, jonka eduskunta myönsi THL:lle koronaepidemian yhteiskunnallisten vaikutusten tutkimukseen. Kysely ajoittui vuosien 2020–2021 vaihteeseen, ja sen kohderyhmänä olivat 1.10.2014–30.9.2015 välisenä aikana syntyneiden lasten vanhemmat. Kyselyssä tarkasteltiin lasten hoito- ja varhaiskasvatus…

Multiple solutions for a Sturm-Liouville problem with periodic boundary conditions

2013

The main purpose of this paper is to establish the existence of multiple solutions for a Sturm-Liouville problem with periodic boundary conditions. The approach is based on variational methods and multiple critical points theorems

MobileMonday culture : the lure of participatory space

2010

This master’s thesis explores participatory culture’s social logic and its manifestations in social media. It employs the case study method to examine participatory culture’s patterns of interaction through the experiences of participants in Mobile Monday, a global community sharing common professional interests in mobile communications. It provides an historical perspective on the technology and concepts used in social media, and applies a theoretical framework based on the premise of participatory culture as a manifestation of the postmodern condition, influenced by tacit aesthetics, and dominated by media culture. The framework includes aesthetic strategies related to social media and th…
