Care in academia: an exploration of student parents’ experiences

While student parents now represent a significant proportion of the higher education population in England, this group has been given limited consideration in policy circles. Using a social constructivist and feminist theoretical framework, this paper draws on a research project investigating the role of higher education policies in supporting student parents in England. It focuses on findings from 40 interviews conducted with student parents enrolled on university programmes. It shows that, in the context of the default construction of the university student as carefree, student parents often describe their experience of navigating academia as a struggle, in which time-related, financial, health and emotional problems prevail. However, the stories they tell also emphasise the benefits associated with their dual status. By doing so, they resist the discourse of deficit typically applied to ‘non traditional’ students and produce a counter-discourse that disturbs the long-lived binary opposition between care and academia.     

Conservation of stained glass windows with protective glazing: Main results from the European VIDRIO research programme

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation.     

An Epistemological Approach to French Syllabi on Human Origins during the 19th and 20th Centuries

This study focuses on how human origins were taught in the French Natural Sciences syllabuses of the 19th and 20th centuries. We evaluate the interval between the publication of scientific concepts and their emergence in syllabuses, i.e., didactic transposition delay (DTD), to determine how long it took for scientific findings pertaining to our topic to be introduced in teaching. Conceptions were categorised into four successive periods, each of which lasted approximately half a century. We showed that the DTD on human origins was influenced in each period by the conceptions of the curriculum developers, by the educational system and, more generally, by the socio-political context.     

New media,old images: constructing online representations of women and men in science,engineering and technology

This paper looks at online representations of women and men in science, engineering and technology. We show that these representations largely re/produce dominant gender discourses. We then focus on the question: How are gender clichéd images re/produced online? Drawing on a discursive analysis of data from six interviews with web authors, we argue that there are two reasons why their awareness of gender issues does not always translate into website content. First, web authors think of themselves as working within either journalistic or scientific cultures, and draw on associated criteria, which exclude gender equity, to make content decisions. Second, they construct distinctions between representation and reality, judging representations on their ‘empirical realism’ (how accurately they represent a reality seen to exist outside the text), foreclosing considerations of their productive power. Finally, we draw on interview data with young people to show that these constrain the meanings made by web users.     

Attention-seeking during caregiver unavailability and collaboration at age 2

Several theoretical approaches have discussed the role of children's expectations of their parent's responsiveness in explaining motivation to collaborate in acquiring skills. This study attempted to measure these expectations in 102 toddlers (M age = 26.4 months) through observations of attention-seeking (A-S) behaviors during caregiver's restricted availability. Child collaboration was coded during skill-learning tasks (imitation and block building), and parent responsiveness was observed during dyadic activities. Different A-S styles emerged, supporting the existence of both positive and negative expectations of responsiveness. A-S quality statistically mediated the link between parent responsiveness and child collaborative outcomes, even after controlling for temperament and mood. This is the first study to show that toddlers' expectations are a plausible mechanism linking parent responsiveness to child collaboration.     

Single cell rheometry with a microfluidic constriction: Quantitative control of friction and fluid leaks between cell and channel walls

We report how cell rheology measurements can be performed by monitoring the deformation of a cell in a microfluidic constriction, provided that friction and fluid leaks effects between the cell and the walls of the microchannels are correctly taken into account. Indeed, the mismatch between the rounded shapes of cells and the angular cross-section of standard microfluidic channels hampers efficient obstruction of the channel by an incoming cell. Moreover, friction forces between a cell and channels walls have never been characterized. Both effects impede a quantitative determination of forces experienced by cells in a constriction. Our study is based on a new microfluidic device composed of two successive constrictions, combined with optical interference microscopy measurements to characterize the contact zone between the cell and the walls of the channel. A cell squeezed in a first constriction obstructs most of the channel cross-section, which strongly limits leaks around cells. The rheological properties of the cell are subsequently probed during its entry in a second narrower constriction. The pressure force is determined from the pressure drop across the device, the cell velocity, and the width of the gutters formed between the cell and the corners of the channel. The additional friction force, which has never been analyzed for moving and constrained cells before, is found to involve both hydrodynamic lubrication and surface forces. This friction results in the existence of a threshold for moving the cells and leads to a non-linear behavior at low velocity. The friction force can nevertheless be assessed in the linear regime. Finally, an apparent viscosity of single cells can be estimated from a numerical prediction of the viscous dissipation induced by a small step in the channel. A preliminary application of our method yields an apparent loss modulus on the order of 100 Pa s for leukocytes THP-1 cells, in agreement with the literature data.     

Imagining the mathematician: young people talking about popular representations of maths

This paper makes both a critical analysis of some popular cultural texts about mathematics and mathematicians, and explores the ways in which young people deploy the discourses produced in these texts. We argue that there are particular (and sometimes contradictory) meanings and discourses about mathematics that circulate in popular culture, that young people use these as resources in identity making as (non-)mathematicians, negotiating their meaning in ways that are not always predictable, and that their influence on young people is diffuse and nevertheless important. The paper discusses the discourses that prevail in some of the popular cultural images of mathematics and mathematicians that came up in our research. We show how mathematics is represented as a secret language, while mathematicians are often mad, mostly male and almost invariably white. We then explore how young people negotiate these discourses, positioning themselves in relation to mathematics. Here we draw attention to the fact that both those who continue with mathematics after it ceases to be compulsory and those who do not, deploy similar images of mathematics and mathematicians. What is different is how they respond to and negotiate these images.     

Becoming a secondary school teacher in England and France: contextualising career ‘choice’

This article explores the circumstances in which individuals become secondary school teachers in England and France. Using a social constructivist theoretical framework, it specifically considers how national contexts play out in this decision. The findings presented in this paper draw on a corpus of 60 interviews with a sample of teachers based in English and French secondary schools. They show that national frameworks remain relevant to an exploration of teachers’ identities and cultures, as French and English interviewees draw on distinctive reasons to explain why they became secondary school teachers. While becoming a teacher is often thought of as a ‘vocation’ or as the result of ‘intrinsic’ factors, this paper highlights the role of national contexts, as well as of gender and social class, in this process.
