Engaging Fathers in Child Nutrition: Exploring Intra-household Gender Dynamics in Nutrition Interventions in Ethiopia.

This study aims to examine intra-household gender dynamics in response to a nutrition intervention (maternal Behaviour Change Communication (BCC), paternal BCC, and food vouchers) aimed at improving IYCF practices using qualitative methods. Participants were drawn from a subset of households enrolled in a larger cluster - randomized controlled trial (RCT) conducted in rural Ethiopia. A total of 40 participants (20 mother-father pairs) from intervention and control households were interviewed separately to explore intra-dyadic beliefs and household decision-making.

Hybrid BCI for Meal-Assist Robot Using Dry-Type EEG and Pupillary Light Reflex.

Brain-computer interface (BCI)-based assistive technologies enable intuitive and efficient user interaction, significantly enhancing the independence and quality of life of elderly and disabled individuals. Although existing wet EEG-based systems report high accuracy, they suffer from limited practicality. This study presents a hybrid BCI system combining dry-type EEG-based flash visual-evoked potentials (FVEP) and pupillary light reflex (PLR) designed to control an LED-based meal-assist robot.

Behaviour change communication to improve complementary feeding practices in Ethiopia: Couples' beliefs concerning paternal involvement in childcare.

An important cause of stunting is limited consumption of complementary foods, in terms of both quantities and nutrients. Although existing studies show a positive association between fathers' engagement and children's diet, programmes designed to improve complementary feeding practices often only target mothers. In response to this, maternal behaviour change communication (BCC), paternal BCC and food voucher programmes were designed and implemented in Ethiopia using a clustered randomized controlled trial design.

Engaging Fathers Through Nutrition Behavior Communication Change Does Not Increase Child Dietary Diversity in a Cluster Randomized Control Trial in Rural Ethiopia.

Background: Adding food vouchers or paternal nutrition behavior change communication (BCC) activities to maternal BCC may improve child diets and household food security but their effect is unknown.

Objectives: We assessed whether maternal BCC, maternal and paternal BCC, maternal BCC and a food voucher, or maternal and paternal BCC and a food voucher improved nutrition knowledge, child diet diversity scores (CDDS), and household food security.

Methods: We implemented a cluster randomized control trial in 92 Ethiopian villages.

The Roles of Nutrition Education and Food Vouchers in Improving Child Nutrition: Evidence from a Field Experiment in Ethiopia.

Mothers' lack of knowledge about child nutrition and limited resources lead to poor diets among children in developing countries, increasing their risk of chronic undernutrition. We implemented a cluster randomized control trial that randomly provides four-month-long Behavior Change Communication (BCC) and food vouchers in Ethiopia. We find improvements in child-feeding practices and a reduction in chronic child undernutrition only when BCC and vouchers are provided together.

Phase control of quasi-2D perovskites and improved light-emitting performance by excess organic cations and nanoparticle intercalation.

The optoelectronic properties of quasi-two-dimensional organic-inorganic hybrid perovskites can be tuned by controlling the formation of Ruddlesden-Popper type phases, which enables diverse device applications such as photovoltaics and light-emitting diodes (LEDs). Herein, the influence of excess organic cations on the phase formation of (PEA)2MAn-1PbnBr3n+1 is systematically investigated with various mixing ratios to discover the phase distribution beneficial for light-emitting diodes. It is found that PEA cations exceeding Pb ions in molar ratio are required to produce small-n phases in the films with a strong photoluminescence, while excess MA cations enable the formation of more large-n phases.
