The research is guided by the problem of understanding how the municipality manages migration and cross-border labor relations, and to what extent this management contributes to reproducing or challenging the socioeconomic inequalities characteristic of capitalism in border areas. Methodologically, a qualitative approach is adopted, grounded in historical-dialectical materialism, based on bibliographic review, document analysis, field observation, and semi-structured interviews conducted with migrants, employers, public authorities, and institutional agents. The results show that migration to Mercedes is directly associated with material living conditions, being primarily motivated by the search for employment, better wages, and access to basic public services such as health and education. It is observed that migrants are predominantly inserted into lowskilled sectors, such as construction, agro-industry, clothing manufacturing, and services, characterized by low wages, informality, and job instability. The interviews reveal that, although labor enables permanence in the territory, it occurs under conditions marked by precariousness and subordination, evidencing a form of subordinate integration into the local labor market. At the same time, access to universal public policies contributes to the reproduction of life, albeit in a limited manner and not specifically structured for the migrant population. The analysis also demonstrates that municipal public management operates in a fragmented and reactive way, without the consolidation of specific policies aimed at migrants, reinforcing their condition of institutional invisibility. In this context, cross-border governance appears as a secondary element, marked by structural limitations and low effectiveness in promoting social integration. It is concluded that labor simultaneously constitutes a means of integration and a mechanism for reproducing inequalities, revealing that the migrant presence in Mercedes (PR) is embedded in the structural contradictions of capitalism in border territories, where possibilities for permanence coexist with limits to full social integration Publisher: Universidade Estadual do Oeste do Paraná Tipo do documento: Dissertação Wed, 03 Jun 2026 00:00:00 GMT https://tede.unioeste.br/handle/tede/8637 2026-06-03T00:00:00Z https://tede.unioeste.br/handle/tede/8605 Title: O acolhimento das crianças migrantes haitianas nos Centros Municipais de Educação Infantil em Toledo - PR Autor: Kern, Aionã Vieira do Prado Primeiro orientador: Campos, Bruno Ferreira Abstract: This dissertation investigates the welcoming process of Haitian migrant children in the Municipal Centers for Early Childhood Education (CMEIs) in Toledo, Paraná. Given the significant increase in international migratory flows to Brazil, and specifically to Western Paraná, this research examines to what extent educational institutions are prepared for the integration of this population. The study adopts a qualitative, exploratory approach structured in three stages: a literature review; an analysis of data from official sources such as IBGE and INEP; and field research conducted through semi-structured interviews with public administrators, educators, and Haitian families. The selection of the schools for the field study was based on the areas with the highest concentration of Haitian children enrollments in the municipality. The results demonstrate that, although access to education is guaranteed, effective welcoming is hindered by a "normative vacuum" and a lack of specific institutional guidelines, which delegates the individual responsibility for managing intercultural complexities to educators. It was identified that the language barrier constitutes the most immediate obstacle, hindering the bond between school and family and full curricular integration. On the other hand, the teachers' affectivity and the children's rapid adaptation emerge as facilitators of the process. The analysis also shows that the distribution of migrants in Toledo - PR is concentrated in areas near industrial hubs, generating specific demands for the CMEIs in these regions. It is concluded that, despite the municipality's progress in seeking improvements, it is still necessary to advance in continuing education policies and pedagogical practices that do not merely "treat everyone as equals," but instead recognize and value different cultural identities within the school environment, requiring the implementation of structured public policies.

Unlike important previous studies, this work considers the concurrent occurrence of these two modes of climate variability, including combinations with the same sign and with opposite signs across all ENSO typologies (Eastern, Central, and Mixed). To obtain the results, the IOD phases were initially identified using the Dipole Mode Index (DMI), while the ENSO phases were identified through the Oceanic Niño Index (ONI). The impacts on precipitation over SEAS were assessed using rainfall anomaly composites. To understand the mechanisms associated with these anomalies, composite maps of geopotential height anomalies at 200 hPa and omega anomalies at 200 hPa and 500 hPa were also produced. The results first revealed a predominance of combinations between ENSO and IOD events with the same sign, particularly in the Mixed ENSO typology. Another noteworthy finding was the absence of co-occurrence between Eastern and Central El Niño events with negative IOD (IOD-) events. The dissertation hypothesis — that ENSO effects over SEAS would be stronger when combined with IOD phases of the same sign — was partially confirmed. Events such as Eastern El Niño and Eastern La Niña indeed showed intensified effects when associated with IOD phases of the same sign. However, opposite-sign combinations between the modes, such as Mixed El Niño with IOD-, Central La Niña with IOD+, and Mixed La Niña with IOD+, proved to be more effective in terms of the intensity of impacts over SEAS. Another relevant result was observed in the combination of Central La Niña and IOD-, which produced intense positive precipitation anomalies over SEAS, indicating that, in this case, the Indian Ocean interannual mode outweighed the ENSO effects.

This research aimed to evaluate the influence of rainfall variability on soybean yields in the municipality of Marechal Cândido Rondon – PR, covering the period from the 2009/2010 to 2022/2023 harvest seasons. The methodology adopted a quanti-qualitative approach based on episodic analysis, correlating daily precipitation data and crop phenological phases with productivity indices that showed significant deviations (above or below one standard deviation from the historical average). The role of the El Niño/Southern Oscillation (ENSO) phenomenon during these periods was also investigated. The results demonstrated that the total accumulated rainfall volume during the growing season is not the primary indicator of productive success. Instead, the temporal distribution of precipitation specifically the occurrence or absence of rain during the critical stages of flowering and grain filling (December and January) proved to be the determining factor for local yields. It was observed that a regular distribution of rain during these critical months was capable of neutralizing the drought effects expected in La Niña years, resulting in high yields; a phenomenon discussed here as the "La Niña paradox." Conversely, prolonged dry spells during the reproductive stage were decisive in crop failures, even in years with apparently adequate total rainfall volumes. This study concludes that the quality of episodic rainfall distribution supersedes the generic influence of ENSO, suggesting that short-term monitoring of water conditions is more strategic for local producers than exclusive reliance on seasonal climate forecasts.
