Comparing child and caregiver reports of food insecurity: Agreement and associations with child skills
(Elsevier, 2026-12) Lee, Allan; Aurino, Elisabetta; Wolf, Sharon
Two-thirds of children in low-income countries are affected by food insecurity. Household food insecurity is typically measured using caregiver reports, but children’s reports may shed light on experiences or domains of food insecurity that caregivers overlook. Using a novel validated measure of child-reported food insecurity, we examine how both child- and caregiver-reported food insecurity predicted children's academic, cognitive, and social-emotional skills in a large sample of children (N = 3771, 5–17 years-of-age) and their caregivers in five northern regions of Ghana. Caregivers were nearly twice as likely as children to report food insecurity, with larger discrepancies across items reflecting moderate food insecurity manifestations. In value-added models that aim to control for unobserved heterogeneity that drives skills, caregiver-reported food insecurity predicted lower literacy and numeracy, especially among boys and older adolescents, whereas child-reported food insecurity did not predict any outcome. Potential mechanisms (child health, parental educational investments, children's aspirations, and caregiver psychological well-being) partially accounted for the observed associations. Findings suggest that caregiver reports better capture the constraints induced by food insecurity on children's learning in this context, which is important information for targeting interventions to support child development by tackling food insecurity.
Fruiturisme: The Boost of Fruit Tourism in Catalan Rural Areas
(Taylor & Francis, 2022-08-07) Crespi Vallbona, Montserrat; Farran Plana, Manel
This research involves an in-depth study of tourism as an economic driver in rural areas, specifically in those with prominent entrepreneurship and diversification in agrarian family businesses. We base it on a case study of Fruiturisme, a tourism project being developed in the small town of Aitona (Catalonia) which offers the experience of viewing fruit trees in bloom. In-depth interviews to local stakeholders are used to collect data and provide arguments to reinforce entrepreneurship and diversification in agrarian family businesses. We highlight the characteristics that foster the development and continuity of such agrotourism projects in domestic and international markets, as well as the sustainability of agrarian family businesses. The support and developmental drive by Aitona Town Council, together with the endogenous collaboration of the residents of the entire municipality, has generated an ideal scenario in which to create a tourist product that is recognized nationally and internationally. The contribution of this article is to highlight this cogovernance of different staketholders to implement tourism activities and to go on with this collaboration to diversify the business activity of different farms and entrepreneurship in the town. Otherwise, rural places will have an uncertain future, but agriculture and tourism are a pairing of great value. Furthermore, this cogovernance and community participation raise as key strategies to develop sustainable tourism.
<em> </em>Training and development pathways: How self-perceived managerial competencies, self-efficacy, and protean career orientation shape graduates’ early career success
(Emerald Publishing, 2026-02-27) Mach i Piera, Mercè; Abrantes, António C. M.; Ferreira, Aristides Isidoro
This study aims to examine how shifting organizational dynamics and boundaryless career trajectories shape contemporary career paradigms, with a focus on protean careers. Grounded in social cognitive career theory, it investigates how protean career orientation, self-efficacy and self-perceived managerial competencies acquired through higher education influence subjective career success.
L’última casa. Reflexions etnogràfiques sobre la vellesa a través de l’anàlisi dels espais de les residències geriàtriques
(2026-09-14) Polío Anguera, Eva; Argudo Portal, Violeta; Vergnano, Cecilia
A través d’un treball etnogràfic en quatre residències geriàtriques de Catalunya, analitzo com la vida quotidiana de les persones grans en situació de dependència s’organitza material i institucionalment. Per fer-ho, em centro en tres espais: l’habitació, el bany i el cancell d’entrada. L’habitació promet continuïtat domèstica, però es configura com un espai assistencial mínim i regulat, pensat més des d’una lògica laboral que habitacional; el bany i el bolquer mostren com la intimitat corporal és reorganitzada segons els temps disponibles, les ràtios de personal i els dispositius de delegació; i el cancell evidencia que la relació amb l’exterior queda administrada mitjançant portes, registres, autoritzacions i formes de control. Si l’habitatge i la capacitat de fer llar formen part de les possibilitats de cura, una infraestructura de cura que ho dificulta només cuida parcialment.
Determination of crAssphage in water samples and applicability for tracking human fecal pollution
(Applied Microbiology International, 2017-11) García Aljaro, Cristina; Ballesté Pau, Elisenda; Muniesa Pérez, Ma. Teresa; Jofre, Juan
In recent decades, considerable effort has been devoted to finding microbial source-tracking (MST) markers that are suitable to assess the health risks of faecally polluted waters, with no universal marker reported so far. In this study, the abundance and prevalence of a crAssphage-derived DNA marker in wastewaters of human and animal origins were studied by a new qPCR assay with the ultimate aim of assessing its potential as an MST marker. crAssphage showed up to 106 GC/ml in the sewage samples of human origin, in both the total DNA and the viral DNA fraction. In wastewaters containing animal faecal remains, 39% of the samples were negative for the presence of the crAssphage sequence, while those showing positive results (41% of the samples) were at least 1 log10 unit lower than the samples of human origin. Noteworthy, the log10 values of the ratio (R) crAssphage (GC/ml)/Escherichia coli (CFU/ml) varied significantly depending on the human or animal origin (R > 1.5 for human samples and R < −1.5 for animal wastewater samples. This study opens the way for further research to explore if different specific animal variants of crAssphage exist and whether other zones of the crAssphage genome are better suited to source discrimination.
