Preparing Offspring for a Dangerous World: Potential Costs of Being Wrong

Adaptive maternal responses to stressful environments before young are born can follow two non-exclusive pathways: either the mother reduces current investment in favor of future investment, or influences offspring growth and development in order to fit offspring phenotype to the stressful environment. Inducing such developmental cues, however, may be risky if the environment changes meanwhile, resulting in maladapted offspring. Here we test the effects of a predator-induced maternal effect in a predator-free postnatal environment. We manipulated perceived predation-risk for breeding female great tits by exposing them to stuffed models of either a predatory bird or a non-predatory control. Offspring were raised either in an environment matching the maternal one by exchanging whole broods within a maternal treatment group, or in a mismatching environment by exchanging broods among the maternal treatments. Offspring growth depended on the matching of the two environments. While for offspring originating from control treated mothers environmental mismatch did not significantly change growth, offspring of mothers under increased perceived predation risk grew faster and larger in matching conditions. Offspring of predator treated mothers fledged about one day later when growing under mismatching conditions. This suggests costs paid by the offspring if mothers predict environmental conditions wrongly.

Regulation of fetal growth: consequences and impact of being born small

The first trimester of pregnancy is the time during which organogenesis takes place and tissue patterns and organ systems are established. In the second trimester the fetus undergoes major cellular adaptation and an increase in body size, and in the third trimester organ systems mature ready for extrauterine life. In addition, during that very last period of intrauterine life there is a significant increase in body weight. In contrast to the postnatal endocrine control of growth, where the principal hormones directly influencing growth are growth hormone (GH) and the insulin-like growth factors (IGFs) via the GH-IGF axis, fetal growth throughout gestation is constrained by maternal factors and placental function and is coordinated by growth factors. In general, growth disorders only become apparent postnatally, but they may well be related to fetal life. Thus, fetal growth always needs to be considered in the overall picture of human growth as well as in its metabolic development.

Work Experiences and Well-Being in the First Years of Professional Work in Switzerland: A Ten-Year Follow-Up Study

The ÆQUAS (a German acronym for “Work Experiences and Quality of Life in Switzerland”) study followed young workers in five occupations over their first ten years in the labor market. Participants of the study reported on working conditions and well-being at five occasions. Overall, resources at work as well as well-being, health and personal resources remained stable or increased. Concurrently, task-related stressors increased as well. This result may reflect career progress (e.g., gaining more responsibilities may be accompanied by increasing time pressure) but development in task-related stressors as well as resources may also be related to specific occupations. Several trajectories had their turning point after the first or second year of being in the labor market, which may reflect a successful professional socialization. Even though a substantial number of participants did change their occupation over these ten years (with benefits for their well-being), development over the first ten years after vocational training implies a successful transition into labor market.

Displaced Stories: The Interplay of Telling and Being in the Face of Displacement

Throughout the last decades, narrative approaches have become quintessential tools for understanding crisis and displacement. While a focus on individual stories allows for a deep look into the particularity of being-displaced, it simultaneously runs the risk of romanticising the outcome (the life story) of what is indeed the product of a rather complex process (the telling of the life story). In this paper I will discuss a change of perspectives: Rather than laying the focus on life stories as texts, I will suggest to shift the attention towards the existential dynamics of storytelling. By zooming in on my longstanding collaboration with a Somali woman in Melbourne, Australia, I will map out the interplay of telling and being that marked this process. Focusing on one particular storytelling moment, I will suggest the importance of appreciating the intersubjective force of storytelling. Rather than melting the set of stories into a coherent “life story”, I will look at the storytelling moment in its lived messiness. In doing so, I will sketch out its potential to shed light both on the teller’s hopes, imaginations and ambitions, and on the reality of being part of a wider world that often contradicts and shatters these hopes.
