Brazil has a longstanding and significant tradition in the development of social housing; however, this topic remains underexplored within the field of social policy. This study adopts qualitative methods, including an analysis of housing legislation, from the past two decades and, and data from 20 semi-structured interviews conducted between June and September 2021 with key stakeholders in housing policy, such as policymakers, and activists. The findings reveal a persistent gap between policy promises and actual implementation, alongside a continuing trend toward the financialization and commodification of social housing – particularly in programs such as Minha Casa, Minha Vida (My House, My Life) and Casa Verde e Amarela (Green and Yellow House). The study offers novel empirical insights into the role of social housing within broader ecosocial policy frameworks. One of the central findings is the interconnection between social housing, environmental concerns, and sustainability. The Brazilian case, in particular, stands out as a distinctive and pioneering contribution to the field.

The Painel USP de Gêmeos (University of São Paulo Twin Panel) is, based at the Instituto de Psicologia da Universidade de São Paulo. It was formally established in 2017 to advance research on fundamental psychological processes through twin study designs. Our relatively new registry comprises a volunteer sample of 8839 twin individuals, 70% of whom live in Brazil’s Southeast, the region with the highest twinning birth rate (10.64‰) of the country, within a national population of 213 million. Our collaborative research group has expanded to include partners from psychology, dentistry, and medicine at USP, as well as other Brazilian institutions, such as the Universidade Federal do Rio Grande do Norte, Universidade Federal da Bahia, and Universidade Federal do Espírito Santo. We are advancing biobehavioral research in Brazil through innovative methodologies, interdisciplinary collaboration, and international partnerships. All twin participants contribute to multiple studies associated with four datasets employing the same hierarchical identification system for participants and families: the Biorepository, the Physiological and Physical Repository, the Behavioral Repository, and Fonoteca Cesar Ades (FOCA). Future directions include expanding our twin registry across the five regions of Brazil, our research partnerships, promoting genetic literacy, and fostering public engagement.

The oceanic anglerfishes (Lophiiformes: Ceratioidei) are among the most diverse and ecologically distinctive groups of deep-sea fishes, exhibiting some of the most extreme morphological adaptations in the marine realm. Despite their remarkable biological traits, they remain among the most understudied vertebrates globally, primarily due to the logistical challenges associated with accessing their natural habitats. Here we report the diversity of oceanic anglerfishes collected during the AMAZOMIX scientific cruise, conducted in 2021 off northern Brazil, including the Amazon River plume, across depths ranging from the surface to approximately 1200 m. A total of 34 ceratioid specimens, representing six families and eight genera, were collected. Seven species were identified: Melanocetus johnsonii (Melanocetidae), Haplophryne mollis (Linophrynidae), Lophodolos acanthognathus, Oneirodes carlsbergi (Oneirodidae), Centrophryne spinulosa (Centrophrynidae), Gigantactis vanhoeffeni and Rhynchactis leptonema (Gigantactinidae). Haplophryne mollis, L. acanthognathus, C. spinulosa, and R. leptonema are reported for the first time in Brazilian waters. This study provides morphological and distributional remarks for all identified species and presents an updated checklist of deep-sea anglerfishes recorded in Brazilian waters.

This paper contributes to the emerging field of forest pedagogies by foregrounding mangroves as critical sites for learning with more-than-human entanglements in polluted worlds. Engaging with planetary strategies of corresponding, evidencing and circulating, we approach mangroves as complex, contested and vital ecotones. We explore how mangroves invite pedagogical attention to the lived realities of toxicity, urbanisation and forms of contamination in the emergence of the Anthropocene. We conceptualise mangroves as “unruly edges” that unsettle binary distinctions between forest and estuary, fresh and saline waters and call for an estimation, historisation and analyses of interspecies entanglements. This position grounds a critical pedagogical project of “riparian struggles,” fostering mutual learning among river-zone inhabitants across planetary contexts. Through a case study in the Guanabara Bay region of Rio de Janeiro, we present filmmaking as a threefold tactic that (1) situates mangrove struggles within broader historical geographies, (2) supports community-based and student learning with contaminated ecologies and (3) circulates tactics of mangrove struggles across academic, educational and public spheres. Ultimately, we propose mangroves as more-than-human classrooms where practices of habitability with toxicity can be cultivated, unsettling paradigms of ecological purity and expanding forest imaginaries within the field of Critical Forest Studies.

In recent years, social entrepreneurs in the third sector have played an increasingly important role in addressing societal problems. Despite their growing presence in civic society, little is known about how social entrepreneurs obtain the necessary skills, knowledge, and motivation to take on this role. This exploratory study empirically addresses this gap through 27 in-depth case studies of social entrepreneurial leaders of third-sector initiatives in Brazil. Findings show that the social entrepreneurs relied on a convergence of experiences including: direct experience with inequality, interaction with target populations, volunteer work, religious institutions, social activism, formal education, professional experience, reading, and intercultural interactions. The study also presents a nuanced understanding of how the interplay among life experiences and learning processes informed these third-sector leaders. Results are relevant to scholars and practitioners committed to fostering social entrepreneurship in the third sector.

The relationship between social innovation venture and poor communities has received little attention from studies in the area of social innovation. In order to clarify this relationship, our study seeks to answer: What strategies would help to bring social innovation ventures closer to poor communities? We developed an empirical and qualitative research in a social innovation venture and two poor beneficiary communities in Brazil. The results indicate that the proximity between those agents was based on five main items: (a) reputation of the social venture; (b) appropriate prices according to the community’s reality; (c) close relations with the community; (d) structure proximity; and (e) winning the community leadership’s trust. Thus, our study contributes to the literature by exploring the beneficiary communities and their relationship with social innovation ventures. In addition, we suggest the use of the term “social innovation venture” to designate a wide range of types of organizations willing to generate social innovation in the practical field.

What are the local characteristics influencing where new nonprofits will be established? How important are community needs, available resources, or the existence of similar organizations for nonprofits’ location? This paper analyzes how the characteristics of 5562 Brazilian municipalities in the year 2000 help explain the location of nonprofits formed between 2001 and 2010. Based on geographically weighted regressions, results indicate that neither access to resources nor poor socioeconomic indicators are powerful influences on nonprofit location in Brazilian municipalities. The main predictor of nonprofit entry is a high pre-existing density of nonprofits in that area. These findings, however, vary across regions and nonprofit fields of activity. By mapping the effect of key explanatory variables, this paper helps understand nonprofit location. The methodology and findings on nonprofit location presented here are novel and may contribute to research in other countries.

Social accountability institutions are at the forefront of democratic reformers’ efforts to improve well‐being by harnessing the power of citizen participation. This article builds on recent research identifying a positive relationship between participatory budgeting (PB) and well‐being. The article is the first large‐N study to identify relationships between specific rules of PB programme design and well‐being. A unique dataset of 114 Brazilian municipalities with PB programmes from 2009 to 2016 is constructed to evaluate whether internal mechanisms within PB explain variation in local infant mortality rates – an outcome associated with wellbeing. Hypotheses are tested that correspond to citizen participation, the scope of deliberation and embeddedness within local institutions. It is found that PB programmes are associated with lower infant mortality rates when they broaden participation, expand deliberation and embed the new institutions in ongoing policy‐making venues. The results offer a framework for designing PB programmes and other social accountability institutions to maximise impact.

From the study of sign languages we know that the visual modality robustly supports the encoding of conventionalized linguistic elements, yet while the same possibility exists for the visual bodily behavior of speakers of spoken languages, such practices are often referred to as ‘gestural’ and are not usually described in linguistic terms. This article describes a practice of speakers of the Brazilian indigenous language Nheengatú of pointing to positions along the east-west axis of the sun’s arc for time-of-day reference, and illustrates how it satisfies any of the common criteria for linguistic elements, as a system of standardized and productive form-meaning pairings whose contributions to propositional meaning remain stable across contexts. First, examples from a video corpus of natural speech demonstrate these conventionalized properties of Nheengatú time reference across multiple speakers. Second, a series of video-based elicitation stimuli test several dimensions of its conventionalization for nine participants. The results illustrate why modality is not an a priori reason that linguistic properties cannot develop in the visual practices that accompany spoken language. The conclusion discusses different possible morphosyntactic and pragmatic analyses for such conventionalized visual elements and asks whether they might be more crosslinguistically common than we presently know.
