The role of heterochrony in Schizanthus flower evolution- a quantitative analysis
2021
Abstract Changes in the timing of development within a lineage (heterochrony) have an enormous impact on floral diversification. However, comparative quantitative studies in a broad range of ontogenetic stages are still needed to identify the role of different heterochronic processes shaping diversification patterns. In this study, changes in petal development were compared across species in the genus Schizanthus showing floral diversification mediated by pollinators. In this genus, transitions from bee- to hummingbird- and moth- pollination are associated with lower lip diversification. Variation in size and shape of petals was quantified at key ontogenetic stages by using a traditional an…

Identification of isomeric states in the N=73 neutron-deficient nuclei 132Pr and 130La
2012
Decays from isomeric states in the neutron-deficient N=73 nuclei 132Pr and 130La have been observed for the first time. Half-lives of 486(70) ns and 2.46(4) μs were measured for two isomeric states in 132Pr. The decay from the 486ns (8 -) isomer has been interpreted as a hindered E1 transition from the bandhead state of the excited πh 11/2νg 7/2 configuration. The decay from the 2.5 μs (8 +) isomer is consistent with the Weisskopf estimate for a low-energy E2 transition. An analogous 0.74(3) μs decay from an (8 +) isomer in the neighboring isotone 130La has also been observed which similarly can be explained if the transition has E2 character. The Weisskopf interpretation for the isomer hin…
Kulttuuri ja aids-kriisi : vastikkeellinen seksi tansanialaisessa slummissa
2018
Artikkelissa tarkastellaan etnologian keinoin miksi Tansanian nuoriso harjoittaa korkean hivtartuntariskin omaavia seksuaalisia käytänteitä. Tutkimus perustuu Tansanian suurimmassa kaupungissa Dar es Salaamissa tehtyihin 128 teemahaastatteluun. Analyysin lähtökohtana on ajatus siitä, että kulttuuristen odotusten ja asenteiden huolellinen analyysi antaa tutkijoille mahdollisuuden löytää uusia ratkaisuja hiv-tartuntariskin vähentämiseksi köyhillä kaupunkialueilla Saharan eteläpuolisessa Afrikassa. peerReviewed
Temperament and Early Intentions to Retire
2019
Abstract Objective: To examine associations between temperament traits and early retirement intentions. Methods: In the Northern Finland Birth Cohort 1966, we analyzed early retirement intentions at the age 46 according to Cloninger temperament traits at the age 46 (n = 4409) and at the age 31 (n = 3226). Ordinal logistic regression analyses were used. Adjustments were made for marital status, education, work type, job satisfaction, perceived health, and mental health problems. Results: 11% of men and 9% of women had strong retirement intentions. Especially higher harm avoidance was associated with higher early retirement intentions in both sexes at the age of 46. A similar pattern of resul…
Media portrayals of transitions from work to retirement in two ageing societies : the case of ageing baby boomers in Japan and Finland
2021
This article explores media portrayals of the transition from work to retirement under the circumstances of demographic change through a focus on newspaper discussions about ageing baby boomers in Japan and Finland. Due to their shared characteristics as a distinct population group that advances the rapid ageing of the population, media representations of Japanese and Finnish baby boomers during the transitional period to retirement give insight into the social perceptions of retirement and their implications on later life. Manifest content analysis and subsequent thematic analysis identify that the topic of “work, retirement and pension” dominates media discussions in both countries. Analy…

Meir-Keeler Type Contractions for Tripled Fixed Points
2012
Abstract In 2011, Berinde and Borcut [6] introduced the notion of tripled fixed point in partially ordered metric spaces. In our paper, we give some new tripled fixed point theorems by using a generalization of Meir-Keeler contraction.
A Geant4 simulation package for the sage spectrometer
2012
International audience; A comprehensive Geant4 simulation was built for the SAGE spectrometer. The simulation package includes the silicon and germanium detectors, the mechanical structure and the electromagnetic fields present in SAGE. This simulation can be used for making predictions through simulating experiments and for comparing simulated and experimental data to better understand the underlying physics.
