Socio-Reproductive Conflicts and the Father’s Curse Dilemma
2018
Evolutionary conflicts between males and females can manifest over sexually antagonistic interactions at loci or over sexually antagonistic interests within a locus. The latter form of conflict, intralocus sexual conflict, arises from sexually antagonistic selection and constrains the fitness of individuals through a phenotypic compromise. These conflicts, and socio-reproductive interactions in general, are commonly mediated by hormones, and thus predictive insights can be gained from studying their mediating effects. Here, we integrate several lines of evidence to describe a novel, hormonally mediated reproductive dilemma that we call the father’s curse, which results from an intralocus co…
Estrogen Regulates the Satellite Cell Compartment in Females
2019
SUMMARY Skeletal muscle mass, strength, and regenerative capacity decline with age, with many measures showing a greater deterioration in females around the time estrogen levels decrease at menopause. Here, we show that estrogen deficiency severely compromises the maintenance of muscle stem cells (i.e., satellite cells) as well as impairs self-renewal and differentiation into muscle fibers. Mechanistically, by hormone replacement, use of a selective estrogen-receptor modulator (bazedoxifene), and conditional estrogen receptor knockout, we implicate 17β-estradiol and satellite cell expression of estrogen receptor α and show that estrogen signaling through this receptor is necessary to preven…
Does sex hormone-binding globulin cause insulin resistance during pubertal growth?
2019
Background The directional influences between serum sex hormone-binding globulin (SHBG), adiposity and insulin resistance during pubertal growth remain unclear. The aim of this study was to investigate bidirectional associations between SHBG and insulin resistance (HOMA-IR) and adiposity from childhood to early adulthood. Methods Participants were 396 healthy girls measured at baseline (age 11.2 years) and at 1, 2, 4 and 7.5 years. Serum concentrations of estradiol, testosterone and SHBG were determined by ELISA, glucose and insulin by enzymatic photometry, insulin-like growth factor 1 (IGF-1) by time-resolved fluoroimmunoassays, whole-body fat mass by dual-energy X-ray absorptiometry and …
Empowerment as an affective-discursive technology in contemporary capitalism: insights from a play
2019
Over recent years, an increasing body of research in social and cultural studies has investigated the contemporary processes of social change from the point of view of affective capitalism. In this article, we take under scrutiny one of its technologies, namely, empowerment, by which we mean a state characterised by feelings of strength, ability and power that enable agency. More specifically, we investigate the way empowerment is presented in a cultural product, a play that tells a story about personnel training in a factory, shown in a city theatre in Finland. By linking recent theorisation of affective capitalism with an investigation of the intertextual and interdiscursive relations of …
Speaking out against everyday sexism : Gender and epistemics in accusations of “mansplaining”
2021
In everyday interaction, subtle manifestations of sexism often pass unacknowledged and become internalised and thus perceived as “natural” conduct. The introduction of new vocabularies for referring to previously unnamed sexist conduct would presumably enable individuals to start problematising hitherto unchallengeable sexism. In this paper, we investigate whether and how these vocabularies empower people to speak out against sexism. We focus on the use of the term “mansplaining” which, although coined over 10 years ago, remains controversial and contested. Using Conversation Analysis and Membership Categorisation Analysis, this paper excavates the interactional methods individuals use to f…
Evolution of external female genital mutilation : why do males harm their mates?
2017
Sperm competition may select for male reproductive traits that influence female mating or oviposition rate. These traits may induce fitness costs to the female; however, they may be costly for the males as well as any decrease in female fitness also affects male fitness. Male adaptations to sperm competition manipulate females by altering not only female behaviour or physiology, but also female morphology. In orb-weaving spiders, mating may entail mutilation of external structures of the female genitalia, which prevents genital coupling with subsequent males. Here, we present a game theoretical model showing that external female genital mutilation is favoured even under relatively high cost…
"Keskiluokkaistuva kansakoulunopettajisto" : Jyväskylän opettajaseminaarin opiskelijoiden kulttuurisosiaaliset taustat seminaariyhteisössä vuosina 19…
2016
Tässä tutkimuksessa selvitän Jyväskylän kansakouluopettajaseminaarin opiskelijoiden kulttuurisosiaalisia taustoja sekä niiden ilmentymistä seminaarin opetuksessa 1920- ja 1930-luvuilla. Kulttuurisosiaalisella taustalla tarkoitan opiskelijoiden sosioekonomista asemaa ennen seminaariin tuloa. Kulttuurisosiaalisen taustan muodostavat opiskelijan sosiaalinen tausta, taustakoulutus sekä se, miltä paikkakunnalta hän on kotoisin. Sosiaalisella taustalla tarkoitetaan tutkimuksessa opiskelijan perhetaustaan pohjautuvaa yhteiskunnallista sosiaalista statusta. Tutkimuksessa sukupuolella on tärkeä osa tarkastelunäkökulmassa, sillä seminaari oli jaettu nais- ja miesosastoon koko seminaarin toiminnan aja…

FM Anna-Kaisa Ylikotilan Suomen historian väitöskirja Mallikansalaisen säröilevä ihanne – Opettajaksi sopivuuden ja sopimattomuuden määrittely suomalaisessa opettajankoulutuksessa vuosina 1920–1945 tarkastettiin perjantaina 27.8.2021 klo 12 Jyväskylän yliopistossa. Vastaväittäjänä toimi professori Jukka Rantala Helsingin yliopistosta ja kustoksena yliopistotutkija, dosentti Heli Valtonen.

Radikaalisti sukupuolesta : naisten asemaa tutkiva komitea politiikan uudistajana 1960-luvulla
2022
Sanna Marinin johtama hallitus on herättänyt keskustelua intersektionaalista feminismiä edustavalla poliittisella profiilillaan. Akateemisen keskustelun käyttö politiikan muutosvoimana ei kuitenkaan ole uutta, vaan näkyi jo 1960-luvulla muotoillussa tasa-arvopolitiikassa. nonPeerReviewed
Radical sex role ideology and the Finnish gender role movement in the late 1960s
2022
An active discussion of gender roles and the need to renegotiate them took place in the late 1960s in Finland. While previous studies have associated this ‘sex role debate’ with the independent civic organisation Association 9, this article focuses on the wider gender role movement. The article analyses the interplay and differences among the Finnish Women’s Democratic League, the Committee for Women’s Status, and Association 9’s grassroots activism between 1965 and 1970. It demonstrates that similar ideas about sex roles were presented simultaneously in two public spheres: the dominant public, where the ideas were promoted by Association 9, and the people’s democratic counterpublic, which …
