Within this context, coffee in the state of Ceará is particularly relevant for its high quality, as the Baturité Massif regionaccounts for 70% of the state's income, generating employment and local income. The objective is to analyze the profitability of shaded coffee producers in the Baturité Massif, state of Ceará, under deterministic and risk conditions in 2023. The analysis methods are: the analysis of profitability indicators based on parameters of gross income and production costs, and the risk analysis by the Monte Carlo method to estimate the probabilistic distribution of each profitability indicator. The results showed that production has a positive average gross margin, allowing producers to remain in the activity in the short term. The risk analysis showed low risk, and this production is very profitable, as there is a 94% probability that the profit will be higher thanthe sample average.

The resulting curve did not exhibit an inverted U-shaped relationship, as expected. We also concluded that selective waste collection had a positive effect on SW management, but the effect was negative when the service was charged.

Autor(es): Vilhena, Luciana Girão de; Braga, Francisco Laercio Pereira; Lima, Filipe Augusto Xavier; Cardoso, Maione Rocha de Castro; Dal’ Magro, Glênio Piran Abstract: This study aimed to analyze the organic products network in organic and agroecological open-air markets in Fortaleza from the perspective of access and exchange of information between network agents. To this end, interviews were carried out with 42 producers/vendors from five fairs in Fortaleza in 2023 to identify the structural analysis of the fairs’ social networks through the application of the UCINET 6.2 software. The results showed network density of less than 30%, which implies low speed in the circulation of information. Furthermore, it was possible to identify key actors in each of the fairs visited, especially those who reduce paths and hold power in the process of passing on information to the group. It concludes that there is a need for effective public policies aimed at producers/vendors at Fortaleza’s fairs.

The program involved providing laptops to students and training teachers. For this purpose, microdata from the Basic Education Assessment System (Saeb) was used in conjunction with the School Census, conducting school-level analyses using the Fuzzy Regression Discontinuity Design (RDD) method, considering the restriction of a maximum number of eligible students and teachers to participate in the program. In this case, the number of students and teachers predicted by the Maimonides' Rule function developed by Angrist and Lavy (1999) was used as an instrument for the observed quantity. The results revealed that Prouca did not hav significantly impact students in standardized Portuguese language and mathematics tests hese findings support the existing literature that evaluates the implementation of ICTs in schools, particularly in developing countries.
