Kahdeksan viikon maksimivoimaharjoittelujakson vaikutus frisbeegolfin rystyheiton lähtönopeuteen
2016
Kairala, J. & Jormakka, J. 2016. Kahdeksan viikon maksimivoimaharjoittelujakson vaikutus frisbeegolfin rystyheiton lähtönopeuteen. Liikuntapedagogiikan pro gradu –tutkielma, s. 41., 4 liitettä. Frisbeegolfin rystyheitto on yleinen heittotyyli, jota käytetään varsinkin pitkän matkan heitoissa. Pelaajalle on suuri etu siitä, mitä kauemmaksi frisbeekiekon saa heitettyä ja siksi fyysiset ominaisuudet nousevat yhä suurempaan rooliin. Lajin oheisharjoittelusta ei ole aikaisemmin tehty yhtään tutkimusta. Teoriassa korkeammat maksimivoimatasot mahdollistavat frisbeekiekon heittämisen pidemmälle. Maksimivoimaa pidetään pohjana nopeusvoiman kehittämiselle (Morrison & Chaconas 2014; Stone ym. 2003). M…
Una más de la familia. Au pairs atrapadas entre el capital humano y la economía moral
2018
In contemporary societies we are witnessing an expansion of the messages of human capital. These messages have as their central dimension idea of the self-entrepreneur, which implies a deepening in the logic of activation, while blurring the wage relations. In this scenario, young people with university degrees are becoming a favourite target in the offensive of human capital. The penetration of these human capital messages can be seen in the discourses of young university students who have been forced to leave the country during the crisis. In the present text we approach the discourses of young women who came out as au pairs. The characteristics of this figure place it in a space halfway …
Microgastrinae (Hymenoptera: Braconidae) in the Forest State of Artikutza (Navarra: Spain): Diversity and Community Structure
2013
Microgastrinae is one of the largest subfamilies of the Braconidae with about 2,000 described species worldwide. These wasps are of enormous ecological interest due to their role in controlling the caterpillar populations. This study analyses diversity and community structure within the Microgastrinae in the Artikutza Forest, located in the Peñas de Aia Natural Park, western Pyrenees, Spain. The specimens were collected in two different habitats: mixed forest and beech forest. A total of 524 specimens, belonging to nine separate genera and 27 species were captured. Alpha, beta and gamma diversity were analyzed. Additionally, the relationship between Microgastrinae phenology and climatic con…
Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards
2022
Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…
La organización del trabajo por proyectos: La fábrica de la precariedad laboral
2019
The project-based organization, considered as a radical reorganization of work around one or more simultaneous projects, is nowadays widespread in large companies and public administrations. According to the managerial way of thinking, this system would be virtuous: by giving more autonomy to the employees in the act of production and by developing their skills through mobility and interdisciplinarity of work teams, it would be able to arouse their full commitment. This study confirms in some way how this opinion has been imposed, but at the expense of precarious working conditions, increasing the dedication of employees and silencing any form of criticism. The research is based on a review…

Microscopic quasiparticle-phonon model in the study of the beta decay of Cd-115
2013
This master’s thesis concerns the use of the microscopic quasiparticle-phonon model in the study of the beta minus decay of Cd-115. The first part of this text concentrates on the theoretical description of nearly spherical open-shell odd-A nuclei by using the microscopic quasiparticle-phonon model. The treatment of the subject is far from exhaustive but all the necessary relations needed in the practical application of the formalism are provided in the text. The second part provides the theory that is needed for the study of beta minus decay. In addition to the general theory of forbidden beta minus decay, also the greatly simplified case of allowed transitions are discussed. Again rather …
Effective axial-vector coupling in beta decay of mass region A = 100 - 134 isotopes
2014
Tutkielmassa tarkastellaan massa-alueen A = 100 - 134 ytimien käyttäytymistä beetahajoamisessa käyttäen QRPA-formalismia. Tavoitteena oli tutkia heikon vuorovaikutuksen efektiivisen aksiaalivektorikytkentävakion gA käyttäytymistä massaluvun A funktiona. Tarkasteltavaksi valittiin kaikki mahdolliset ydintripletit, joissa on "keskellä" kaksoispariton (Z pariton, N pariton) ydin, jolla on 1+-perustila ja kokeellisesti havaittuja beetasiirtymiä kahden kaksoisparillisen naapuri-isobaarinsa kanssa. gA:n arvot kiinnitettiin laskemalla jokaisen kaksoisparittoman ytimen Gamow-Teller-matriisielementtien geometrinen keskiarvo ja sovittamalla se kokeelliseen dataan. Tuloksena saatiin lineaarinen malli …
