Projections of a burgeoning population coupled with global environmental change offer an increasingly dire picture of the state of the world's food security in the not-too-distant future. But how can we transform the current food system to become more sustainable, more equitable and more just? We identify kitchens as sites of transformative innovation in the food system where cooks and chefs can leverage traditional food knowledge about local food species to create delicious and nutritious dishes. Achieving a sustainable food system is a grand challenge, one where cooks in particular are stepping forward as innovators to find solutions.
The present study investigated the effects of nutritional programming through parental feeding on offspring performance and expression of selected genes related to stress resistance in a marine teleost. Gilthead seabream broodstock were fed diets containing various fish oil (FO)/vegetable oil ratios to determine their effects on offspring performance along embryogenesis, larval development and juvenile on-growing periods. Increased substitution of dietary FO by linseed oil (LO) up to 80 % LO significantly reduced the total number of eggs produced by kg per female per spawn. Moreover, at 30 d after hatching, parental feeding with increasing LO up to 80 % led to up-regulation of the fatty acyl desaturase 2 gene (fads2) that was correlated with the increase in conversion rates of related PUFA. Besides, cyclo-oxygenase 2 (cox2) and TNF-α (tnf-α) gene expression was also up-regulated by the increase in LO in broodstock diets up to 60 or 80 %, respectively. When 4-month-old offspring were challenged with diets having different levels of FO, the lowest growth was found in juveniles from broodstock fed 100 % FO. An increase in LO levels in the broodstock diet up to 60LO raised LC-PUFA levels in the juveniles, regardless of the juvenile’s diet. The results showed that it is possible to nutritionally programme gilthead seabream offspring through the modification of the fatty acid profiles of parental diets to improve the growth performance of juveniles fed low FO diets, inducing long-term changes in PUFA metabolism with up-regulation of fads2 expression. The present study provided the first pieces of evidence of the up-regulation of immune system-related genes in the offspring of parents fed increased FO replacement by LO.
This article examines collective petitioning in metropolitan Spain during the Age of Revolution, focusing on the practices and discourses that framed petitioning as a meaningful form of action. There was a deeply rooted tradition of petitioning in old regime Spain, which was part of the ordinary bureaucratic workings of the crown and also provided a legitimizing framework for rioting in specific contexts. The collective experimentation in popular participation after the 1808 Napoleonic invasion transformed petitioning. Petitioning was first reconceptualized in accordance with the emerging language of rights and popular sovereignty. Activists and commentators had some awareness of the use of public petitioning in Britain, and once the representative Cortes met in Cadiz in 1810, public petition drives on public issues became part of the political culture. At the same time, the need to legitimate unconventional forms of action in the context of a crisis in the state converted petitioning into an all-embracing right. The right to petition, not only encompassed signed protest texts but also legitimated the old tradition of petitioning by riot and further was used to justify provincial rebellions, juntas, and military pronunciamientos. In comparative terms, this article highlights the elasticity of the language of petitioning during the Age of Revolution and cautions against narrowly associating it with one particular form of collective action or historical trajectory.
Parenting interventions have important consequences for the wellbeing and emotional competences of parents and their children. Technology provides an opportunity with advantages for psychological intervention. The aim of this systematic review and meta-analysis is to analyze the characteristics and effectiveness of technology-based interventions for parents to promote children's physical health or psychological issues.
We conducted a systematic review and meta-analysis for articles about parenting skills for prevention or treatment of children's physical or psychological concerns using technology. We explore the aim of the intervention with parents, kind of problem with children, intervention model, instruments, methodological quality, and risk of bias. A random-effects meta-analysis was conducted.
Twenty-four studies were included in the systematic review and a meta-analysis of 22 studies was performed to find out the effects of intervention depending on the kind of problem, intervention model, follow-up, type of intervention, type of control condition, and type of outcome data. Results show the usefulness of technology-based therapy for parenting interventions with moderate effect sizes for intervention groups with statistically significant differences from control groups.
Technology-based parenting programs have positive effects on parenting and emotional wellbeing of parents and children. Attendance and participation level in technology-based treatment increase compared with traditional parenting intervention.
Popper’s ‘Situational Analysis’ (SA) constitutes his methodological proposal for the social sciences. We claim that the two hallmarks of SA are: (i) that scientists assume they possess a ‘wider’ view of the problem-situation than actors do, and (ii) use the model as an ideal ‘benchmark’ scenario to identify the deviation of actors’ actual behaviour from the former. We argue that SA is not a generalization of the neoclassical theory of individual behaviour but captures instead the methodology adopted by modern behavioural economists. Last, we argue that SA highlights a way of acquiring knowledge that has gone unnoticed in the literature.
The article addresses the history of the ‘Estatuto del Peón’ (peons’ statute or rural workers’ code), one of the most emblematic measures of the so-called ‘first Peronism’. It tries to weigh the importance of this legendary Peronist act for the actors directly involved and in particular to calibrate the magnitude of the Statute's impact on the everyday life and working conditions of Argentina's rural workers. I analyse in detail how the decree was conceived and the novelties it brought in terms of rights and regulations for rural workers. It also uses trial records to explore the implementation of the Statute and its concrete effects, in terms of both working conditions and the juridical protections offered to rural peons.
Androgens have been shown to exert a cysticidal effect upon Taenia crassiceps, an experimental model of cysticercosis. To further inquire into this matter, the Taenia crassiceps model was used to evaluate the expression of several proteins after testosterone (T4) and dihydrotestosterone (DHT) in vitro treatment. Under 2-D proteomic maps, parasite extracts were resolved into approximately 130 proteins distributed in a molecular weight range of 10–250 kDa and isoelectrical point range of 3–10. The resultant proteomic pattern was analysed, and significant changes were observed in response to T4 and DHT. Based on our experience with electrophoretic patterns and proteomic maps of cytoskeletal proteins, alteration in the expression of isoforms of actin, tubulin and paramyosin and of other proteins was assessed. Considering that androgens may exert their biological activity in taeniids through the non-specific progesterone receptor membrane component (PGRMC), we harnessed bioinformatics to propose the identity of androgen-regulated proteins and establish their hypothetical physiological role in the parasites. These analyses yield a possible explanation of how androgens exert their cysticidal effects through changes in the expression of proteins involved in cytoskeletal rearrangement, dynamic vesicular traffic and transduction of intracellular signals.
