Enriching gender in physics education research: A binary past and a complex future
2016
[This paper is part of the Focused Collection on Gender in Physics.] In this article, we draw on previous reports from physics, science education, and women’s studies to propose a more nuanced treatment of gender in physics education research (PER). A growing body of PER examines gender differences in participation, performance, and attitudes toward physics. We have three critiques of this work: (i) it does not question whether the achievements of men are the most appropriate standard, (ii) individual experiences and student identities are undervalued, and (iii) the binary model of gender is not questioned. Driven by these critiques, we propose a conception of gender that is more up to date…
Reading, Gender, and Engagement : Lessons From Five PISA Countries
2014
The authors, members of the PISA/PIRLS Task Force, provide a summary of major gender differences in performance found overall on PISA 2009, along with relevant trends since 2000. The five countries represented by the authors are highlighted in this summary, which includes findings related to the interaction of engagement and reading literacy achievement by gender. These data are foregrounded from PISA because they add further evidence of a serious global pattern of boys’ underachievement in reading and lower reading engagement relative to girls. This is followed by a discussion of what each of our five countries has done in response to the gender gap in reading literacy. The article conclud…

Kielen kärjellä karkea kirjain
2017
Kirja-arvio teoksesta Rinnekangas, Rax: Kadonnut kieli. LURRA Editions, 2015. 208 sivua. ISBN 978-952-5850-54-3. Kadonnut kieli on kosmopoliittina kirjailijana, valokuvaajana, elokuvaohjaajana ja kustantajana tunnetun Rax Rinnekankaan (s. 1954) kirjan mittainen polveileva essee kielestä ja sen suhteesta niin kulttuuriin kuin ihmisyyteen. Teos peräänkuuluttaa ajattelun ja sanojen mahdin tunnistamista aikana, jolloin arvoa on tapana antaa vain asioille, jotka hetkellisesti auttavat loputtoman tylsistynyttä länsimaista ihmistä selviämään arjesta, jotta tämä voi jatkaa sisällyksetöntä kuluttamista. nonPeerReviewed
Maailman ensimmäinen nainen - Eleanor Rooseveltin roolin ja kirjoitusten poliittisuus My Day - kolumneissa 1936-1941
2013
1930-luvun taitteessa puhjennut maailmanlaajuinen lama koetteli erityisen ankarasti Yhdysvaltoja ja leimasi maan kehitystä toisen maailmansodan puhkeamiseen asti. Franklin Roosevelt toimi maan presidenttinä vuosina 1933–1945 ja pyrki parantamaan ihmisten elinoloja sosiaalipoliittisella New Deal - ohjelmallaan. Hänen rinnallaan julkisuudessa ja myös poliittisen vaikuttamisen kulisseissa toimi hänen vaimonsa Eleanor Roosevelt, joka uudisti maan ensimmäisen naisen roolia aktiivisuudellaan. Tässä tutkielmassa tarkastellaan Eleanor Rooseveltin poliittista vaikutusvaltaa vuosina 1936–1941 hänen kirjoittamansa My Day – kolumnin kautta. Kolumnisteilla oli 1930-luvulla merkittävä rooli yhdysvaltalai…
Muscle and bone mass in middle‐aged women : role of menopausal status and physical activity
2020
Background. Women experience drastic hormonal changes during midlife due to the menopausal transition. Menopausal hormonal changes are known to lead to bone loss and potentially also to loss of lean mass. The loss of muscle and bone tissue coincide due to the functional relationship and interaction between these tissues. If and how physical activity counteracts deterioration in muscle and bone during the menopausal transition remains partly unresolved. This study investigated differences between premenopausal, early perimenopausal, late perimenopausal, and postmenopausal women in appendicular lean mass (ALM), appendicular lean mass index (ALMI), femoral neck bone mineral density (BMD) and T…
Postmenopausal hormone replacement therapy modifies skeletal muscle composition and function: a study with monozygotic twin pairs
2009
We investigated whether long-term hormone replacement therapy (HRT) is associated with mobility and lower limb muscle performance and composition in postmenopausal women. Fifteen 54- to 62-yr-old monozygotic female twin pairs discordant for HRT were recruited from the Finnish Twin Cohort. Habitual (HWS) and maximal (MWS) walking speeds over 10 m, thigh muscle composition, lower body muscle power assessed as vertical jumping height, and maximal isometric hand grip and knee extension strengths were measured. Intrapair differences (IPD%) with 95% confidence intervals (CI) were calculated. The mean duration of HRT use was 6.9 ± 4.1 yr. MWS was on average 7% (0.9 to 13.1%, P = 0.019) and muscle…
Sex roles and sex ratios in animals
2022
In species with separate sexes, females and males often differ in their morphology, physiology and behaviour. Such sex-specific traits are functionally linked to variation in reproductive competition, mate choice and parental care, which have all been linked to sex roles. At the 150th anniversary of Darwin's theory on sexual selection, the question of why patterns of sex roles vary within and across species remains a key topic in behavioural and evolutionary ecology. New theoretical, experimental and comparative evidence suggests that variation in the adult sex ratio (ASR) is a key driver of variation in sex roles. Here, we first define and discuss the historical emergence of the sex role c…
