title: Urban sprawl and violence: socio-spatial analysis of homicides in the city of São José dos Campos, SP, Brazil

description: Abstract The risk of violent deaths tends do increase in areas of precarious infrastructure. This paper aims to analyze the socio-spatial distribution of homicides in São José dos Campos (SJC), located in the Metropolitan Region in the state of São Paulo, Brazil, from 2015 to 2017, considering the urbanization and urban space structuring processes. The exploratory study, based on secondary data, is grounded on descriptive statistical and spatial analysis of the homicides that occurred in SJC between 2015 and 2017. The overall rate tended to decline in the period and the deaths occurred mainly in two zones of poorer social indicators and recent urban sprawl boosted by housing policies. The research is a warning against the role of public policies in creating violent territories.

title: Synthesis of a chitosan nanoparticle suspension and its protective effects against enamel demineralization after an in vitro cariogenic challenge

description: Abstract Objective Our study aims to synthesize, characterize, and determine the effects of a ChNPs suspension on human enamel after cariogenic challenge via pH-cycling. Methodology ChNPs were synthesized by ion gelation and characterized by Transmission Electron Microscopy (TEM) and Dynamic Light Scattering. Forty enamel blocks were divided into four groups (n=10/group): (i) ChNPs suspension; (ii) chitosan solution; (iii) 0.05% sodium fluoride (NaF) solution; and (iv) distilled water. Specimens were exposed to cariogenic challenge by cycling in demineralization solution (3 h) and then remineralized (21h) for 7 days. Before each demineralization cycle, the corresponding solutions were passively applied for 90 s. After 7 days, specimens were examined for surface roughness (Ra) and Knoop hardness (KHN) before and after the cariogenic challenge; % KHN change (variation between initial and final hardness), and surface topography by an optical profilometer. The data were analyzed by repeated-measures ANOVA, One-way ANOVA, and Tukey tests (α=0.05). Results TEM images showed small spherical particles with diameter and zeta potential values of 79.3 nm and +47.9 mV, respectively. After the challenge, all groups showed an increase in Ra and a decrease in KHN values. Optical profilometry indicated that ChNPs- and NaF-treated specimens showed uneven roughness interspersed with smooth areas and the lowest %KHN values. Conclusion The ChNPs suspension was successfully synthesized and minimized human enamel demineralization after a cariogenic challenge, showing an interesting potential for use as an oral formulation for caries prevention.

title: Brazilian Version of Online Self-Regulated Learning Questionnaire (OSLQ): Evidence of Validity

description: Abstract Self-regulated learning refers to intentional, planned, temporal, dynamic, and complex action. Self-regulatory assessment instruments valid for traditional teaching are not suitable for online environments. This study examinates evidence for validation of the Online Self-Regulated Learning Questionnaire (OSLQ) applied to a sample of 1,434 students from an on-line Pedagogy course, 95.12% women and 4.88% men, ages from 21 to 40 years, from different regions of Brazil. AFE and AFC considering Parallel Analyzes. The results indicated a moderate adjustment for the hypothetical six-factor model. The extraction of two factors by AFE indicated that the model has not been confirmed. This result points to the need of further studies using the instrument, aiming at its availability to research.

title: The effectiveness of protected areas in the Paraná-Paraguay basin in preserving multiple facets of freshwater fish diversity under climate change

description: Abstract Our objective was to evaluate the effectiveness of protected areas (PAs) in the Paraná-Paraguay basin on multiple facets of ichthyofauna, both currently and in future climate change scenarios, based on reaching the 17% of conserved terrestrial and inland water defined by Aichi Target 11. Analyses were carried out vis-à-vis a distribution of 496 native species, modeling for the present and for the future, and in moderate and pessimistic scenarios of greenhouse gases. We calculated species richness, functional richness, and phylogenetic diversity, overlapping the combination of these facets with the PAs. The results indicate that the current PAs of the Paraná-Paraguay basin are not efficient in protecting the richest areas of ichthyofauna in their multiple facets. While there is a larger overlap between PAs and the richest areas in phylogenetic diversity, the values are too low (2.37%). Currently, the overlap between PAs and areas with larger species richness, functional richness, and phylogenetic diversity is only 1.48%. Although this value can increase for future projections, the values of the indices decrease substantially. The relevant aquatic environments, biological communities, and climate change should be considered as part of the systematic planning of PAs that take into consideration the terrestrial environments and their threats.

title: Conflicts over the Right to the City in Fortaleza: disputes between the city's strategic vision and the regulation of ZEIS

description: Abstract Since the beginning of the 20th century, the production of urban space in Fortaleza has followed a logic led by the private sectors, barely regulated by the State, ratified by public investments, consolidating an uneven space. Only after the approval of the Federal Constitution and the City Statute were urban instruments introduced in the Master Plans to reverse that logic, especially the ZEIS. However, either they were not implemented, or, if so, were based on an upside-down logic that favored the city's mercantilist production. Informal settlements remain at risk of eviction, the production of new social housing continues on a peripheral basis, and public investments favor the valorization of land in specific locations. The objective of this article is, therefore, to discuss the preponderance of the mercantilist logic of space production in Fortaleza to the detriment of guaranteeing the Right to the City, even despite the delimitation of the ZEIS in PDPFor (2009). The article is one of the results of the doctoral thesis, which was developed from interviews with the agents involved, consultations of the documents at the City Hall and bibliographical references highlighted throughout the text.

title: Shading Impact analysis from tall buildings over three public spaces in Curitiba/PR

description: Abstract Buildings shading in cities are crucial elements in shaping inviting public spaces adapted to climate changing. In view of the increase in the buildings height defined in the last update of the urban legislation in the city of Curitiba/PR that took place in 2019, this study aims to analyze the impact of shading from surrounding buildings from simulations in three squares located in different zonings not consolidated or expanding which allow buildings with at least six floors. The method composed of different steps from open data, results in different maps for the summer and winter solstices, and equinoxes. The analyzes demonstrate that when the simulation is carried out considering the buildings height with the acquisition of constructive potential, the shading impact on public spaces is considerable, especially in the winter solstice. Considering Curitiba as a city characterized by cold at that time of the year, ample solar access in public spaces can be recommended. It is argued that the study of the impact of buildings shading is a possibility for delimiting more restrictive indices in urban planning processes.

title: Social Innovation: A Study of International Scientific Publication through Network Analysis

description: ABSTRACT Research on social innovation has grown significantly in the last decade. The objective of this study is to map the international scientific production on social innovation, in order to identify and cluster the variables of social innovation, through network analysis. The database used was Scopus, for the period ranging between 2010 and 2020. Through the analysis of the keywords of the articles, 35 categories were grouped, having as a criterion nature and the conceptual similarity, through the Node XL Software. The results demonstrate a network with four clusters: (1) Social Entrepreneurship, Social Value, and Innovation; (2) Co-creation, Technology, and Sustainability; (3) Social Innovation, Organizational Aspects, and Business Model; and (4) the Non-profit Sector, Strategy, and Learning. The most cited categories, beyond social innovation, were social entrepreneurship and organizational aspects, whose focus of analysis takes place at the organizational level, i.e., resources and capabilities needed for the process of developing social innovation. Also, research gaps have been identified, as networks of actors, community, and social innovation ecosystems.

title: Educational Practices and Child Behaviors: Mothers’ and Teachers’ Evaluation

description: Abstract The objective of this study was to describe and compare mothers’ and teachers’ reports concerning their educational social skills and negative practices and children’s behavioral problems and social skills. The mothers and teachers of 81 children participated in this study. The children were assigned to four groups depending on whether they presented problems exclusively at home, school, in both, or none of these contexts. Valid instruments measured educational practices and child behavior. The results show that: (a) mothers and teachers agreed that children with problems in both contexts presented the highest level of impairment; (b) the mothers more frequently reported skills such as affection, adopted negative practices, and identified problem behaviors; (c) the teachers reported more skills such as limit setting. The conclusion is that teachers’ and mothers’ practices differ, and such information can guide preventive programs and interventions.

title: Silicate rocks as an alternative potassium fertilizer for upland rice and common bean crops

description: Abstract: The objective of this work was to evaluate the efficiency of molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2) as sources of potassium for upland rice (Oryza sativa) and common bean (Phaseolus vulgaris) crops, in comparison with the traditional source (KCl). Two experiments - one with each crop - were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates (0, 20, 40, and 80 kg ha-1 K2O) of K. Regardless of the used source, K fertilization increased the leaf K content and grain yield of the upland rice and common bean crops. The agronomic efficiency index (AEI) of the alternative K sources varied according to the crop. For upland rice, the AEI of K2 was 8% higher than that of KCl at the recommended K rate, but similar at the highest rate. For common bean, the AEI values of K1 were close to that of KCl at the rates of 40 and 80 kg ha-1 K2O. The alternative sources K1 and K2 supply K and increase the grain yield of common bean and upland rice, respectively, similarly to KCl.
