Witchcraft in Honduras is an unprotected marginalized woman’s efforts to gain social, economic, and political power through an informal economy by utilizing the cultural belief in the witches’ supernatural power. The Honduran post-colonial Latin American culture allows for a persistent informal economy, in part, based on the commoditization of witchcraft and exorcism. The case study provides a specific example through ethnographic interviews of this under-researched informal economy driven by fear and economic desperation. Further research and analysis of these poorly understood and rarely recorded modern phenomena and the associated informal economy is needed.

The purpose of this paper is to present a comprehensive analysis of the carbon footprint of the Delft University of Technology (TU Delft), including direct and indirect emissions from utilities, logistics and purchases, as well as a discussion about the commonly used method. Emissions are presented in three scopes (scope 1 reports direct process emissions, scope 2 reports emissions from purchased energy and scope 3 reports indirect emissions from the value chain) to identify carbon emission hotspots within the university’s operations.

The carbon footprint was calculated using physical and monetary activity data, applying a process and economic input-output analysis.

TU Delft’s total carbon footprint in 2018 is calculated at 106 ktCO₂eq. About 80% are indirect (scope 3) emissions, which is in line with other studies. Emissions from Real estate and construction, Natural gas, Equipment, ICT and Facility services accounted for about 64% of the total footprint, whereas Electricity, Water and waste-related carbon emissions were negligible. These findings highlight the need to reduce universities’ supply chain emissions.

A better understanding of carbon footprint hotspots can facilitate strategies to reduce emissions and finally achieve carbon neutrality. In contrast to other work, it is argued that using economic input-output models to calculate universities’ carbon footprints is a questionable practice, as they can provide only an initial estimation. Therefore, the development of better-suited methods is called for.

This study explored how Brazilian young adults who cook interact with cooking-related content on social media and how such content fits their cooking routine.

Semi-structured interviews (n = 31) were transcribed, inductively and reflexively thematic analysed.

Interactions happened both in recreational and intentional ways, which coexisted and alternated depending on participants' motives and schedules. Recreational interactions such as browsing and saving happened more for self-entertainment and to some participants, to help meal planning and food shopping. Intentional interactions such as searching and sharing happened to fulfil specific needs which arised on cooking occasions, leading to agency development. Young adults who self-identified as being less experienced in cooking reported checking and comparing many recipes, as well as relying on video features to improve skills and develop self-efficacy. Despite showing agency in cooking-related matters, participants perceived lack of time to cook as an important barrier to cooking more. Intentional interactions with cooking content were linked to more established cooking routines, indicating the importance of social media to young adults' development of self-efficacy and improvement of skills.

The use of social media to search for cooking-related content is recommended by Brazilian dietary guidelines to develop cooking and food skills, but research on if and how the interaction occurs, and the resulting knowledge is put into practice, is scarce. This study addressed this gap and proposed practical implications to inform the development of interventions employing social media to improve young adults' cooking skills and health.
