Introducing Mobile Money in Rural Mozambique: Evidence from a Field Experiment*
Batista, Cátia; Vicente, Pedro C.The limitations of access to finance in Africa, together with the recent boom in cell phone use in that continent, created high expectations regarding the introduction of mobile money in many African countries. The success story of M-PESA in Kenya raised the bar further. We designed and conducted a field experiment to assess the impact of randomized mobile money dissemination in rural Mozambique. For this purpo...
Directed Giving: Evidence from an Inter-Household Transfer Experiment*
Batista, Cátia; Silverman, Dan; Yang, DeanWe investigate the determinants of giving in a lab-in-the-field experiment with large stakes. Study participants in urban Mozambique play dictator games where their counterpart is the closest person to them outside their household. Dictators share more with counterparts when they have the option of giving in kind (in the form of goods), compared to giving that must be in cash. Qualitative post-experiment respon...
Migrant Remittances and Information Flows: Evidence from a Field Experiment*
Batista, Cátia; Narciso, GaiaDo information flows matter for remittance behavior? We design and implement a randomized control trial to quantitatively assess the role of communication between migrants and their contacts abroad on the extent and value of remittance flows. In the experiment, a random sample of 1,500 migrants residing in Ireland was offered the possibility of contacting their networks outside the host country for free over a ...
Propriedades nutricionais e nutracêuticas de grelos e espigos
Batista, Cátia Emanuela OliveiraNeste trabalho, estudaram-se duas das hortaliças cultivadas e tradicionalmente consumidas nas regiões do Norte de Portugal: espigos e grelos, designações que correspondem às inflorescências de couve-nabo (Brassica napus var napus) e de couve-tronchuda ou couve-Portuguesa (Brassica oleracea var costata), respetivamente. Determinou-se a sua composição química, o perfil nutricional e as suas propriedades antioxida...
Valor nutricional e potencial nutracêutico de inflorescências de couve-nabo (Br...
Barros, Lillian; Batista, Cátia Emanuela Oliveira; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.Na Península Ibérica as verduras (silvestres ou tradicionalmente cultivadas) têm sido alimentos importantes na dieta humana. O valor nutricional de verduras e os seus benefícios para a saúde têm sido reconhecidos como importantes alvos de investigação. Os grelos, inflorescências da couve-nabo (Brassica napus L. var. napus) e os espigos, inflorescências da couve-tronchuda (Brassica oleracea L. var. costata DC.) ...

Barros, Lillian; Batista, Cátia Emanuela Oliveira; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.Neste trabalho, avaliou-se a composição nutricional e o potencial nutracêutico, nomeadamente antioxidante, dos grelos, inflorescências da couve-nabo (Brassica napus L. var. napus) e dos espigos, inflorescências da couve-tronchuda (Brassica oleracea L. var. costata). As duas variedades de Brassica estudadas mostraram ser verduras nutricionalmente equilibrados, em particular os espigos que mostraram conter teores...
Nutritional and nutraceutical potential of rape (Brassica napus L. Var. napus) ...
Batista, Cátia Emanuela Oliveira; Barros, Lillian; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.Two traditional cultivated vegetables highly consumed among Northern Portuguese regions were tested for their chemical composition, nutritional profile and in vitro antioxidant properties using four assays: 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radicals scavenging activity, reducing power, inhibition of -carotene bleaching and inhibition of lipid peroxidation by thiobarbituric acid reactive substances (TBARS) a...
Beef burgers patties incorporated with Boletus edulis extracts: lipid peroxidat...
Barros, Lillian; Barreira, João C.M.; Grangeia, Cátia; Batista, Cátia Emanuela Oliveira; Cadavez, Vasco; Ferreira, Isabel C.F.R.The objective of this study was to analyse the lipid peroxidation inhibition in beef burgers after incorporation of Boletus edulis extracts in different concentrations. Beef burgers samples were stored for 8 days, and chemical and nutritional parameters, including the profile in free fatty acids, were evaluated. Furthermore, the inhibition of thiobarbituric acid reactive substances (TBARS) formation, free radic...
Incorporation of Boletus edulis extract in beef burgers patties: preliminary ev...
Grangeia, Cátia; Batista, Cátia Emanuela Oliveira; Raposo, Manuel; Barros, Lillian; Cadavez, Vasco; Ferreira, Isabel C.F.R.The objective of this study was to analyse the antioxidant protective effects of the incorporation of Boletus edulis extract in beef burgers. The relationship of total lipids/fatty acids to lipid peroxidation of hamburger during storage was examined. Beef burgers samples (lipids content: 15–18%) were stored for 8 days, and thiobarbituric acid reactive substances (TBARS) formation inhibition, free radical scaven...
