Abstract Regional climate models (RCM) are the main tools for climate change impacts assessment in hydrological studies. These models, however, often show biases when compared to historical observations. Bias Correction (BC) are useful techniques to improve climate projection outputs. This study presents a multi-criteria decision analysis (MCDA) framework to compare combinations of RCM with selected BC methods. The comparison was based on the modified Kling-Gupta efficiency (KGE’). The criteria evaluated the general capability of models in reproducing the observed data main statistics. Other criteria evaluated were the relevant aspects for hydrological studies, such as seasonality, dry and wet periods. We applied four BC methods in four RCM monthly rainfall outputs from 1961 to 2005 in the Piracicaba river basin. The Linear Scaling (LS) method showed higher improvements in the general performance of the models. The RCM Eta-HadGEM2-ES, corrected with Standardized Reconstruction (SdRc) method, achieved the best results when compared to the observed precipitation. The bias corrected projected monthly precipitation (2006-2098) preserved the main signal of climate change effects when compared to the original outputs regarding annual rainfall. However, SdRc produced significant decrease in monthly average rainfall, higher than 45% for July, August and September for RCP4.5 and RCP8.5 scenarios.

The integrative and comprehensive analysis considering the spatial and temporal representation of the hydrological process, such as the distribution of rainfall, land cover and land use, is a challenge for the water resources management. In tropical areas, energy availability throughout the year defines the rainfall distribution and evapotranspiration rate according to vegetation heterogeneity. To quantify water balance in tropical areas including these heterogeneities in the soil-vegetation-atmosphere relationship, we developed a fully distributed hydrological model called the Rainfall Runoff Balance Enhanced Model (RUBEM). The model was developed under a physics-based process structure, using remote sensing data to represent soil-water balance patterns, such as evapotranspiration, interception, baseflow, lateral flow, recharge, and runoff. The calibration procedure was based on nine global parameters. RUBEM could represent the spatio-temporal heterogeneities (soil, land use and land cover (LULC), topography, vegetation, and climate) in three basins in a tropical area. The results showed good adherence between the processes governing the soil-vegetation-atmosphere relationship according to the humidity indicator and the runoff coefficient. Overall, RUBEM can be used to help improve the management and planning of integrated water resources under climate, land use, and land cover changes in tropical regions.

O reduzido envolvimento social, aspeto central na definição da solidão social, foi analisado numa amostra de 337 crianças portuguesas (171 rapazes), com idades compreendidas entre os três e os cinco anos. Com base em metodologias de observação, realizadas em contexto de Jardim de infância, verificou-se que níveis reduzidos de envolvimento social estão negativamente associados a baixos níveis de competência social, de resiliência e de um elevado ego-controle. A aceitação pelos pares, o impacto e a preferência social, analisados com base nas medidas sociométricas, encontram-se, também, negativamente associados com os níveis de baixo envolvimento social. Os resultados refletem as dificuldades de ajustamento psicossocial destas crianças e enfatizam o seu potencial risco para o desenvolvimento saudável.

El presente estudio busca obtener evidencias de validez y confiabilidad de la Escala de Involucramiento Parental: Actividades de cuidado y socialización en una muestra de padres peruanos de niños y niñas preescolares. Para ello, se reali-zó una traducción y armonización del lenguaje del instrumento a partir de su versión en inglés al español, para luego aplicar la nueva versión a un grupo de 420 padres y 420 madres de niños y niñas de cinco ciudades. La evidencia de la estructura interna se evaluó a través de un análisis factorial confirmatorio multigrupo, utilizando el método de máxima verosimilitud para examinar la estructura de los 26 ítems originales. Durante el análisis, se procedió a la eliminación progresiva de los ítems con bajas cargas factoriales hasta encontrar un modelo con adecuados indicadores de ajuste [χ2(531) = 822.82; p < .001; χ2/gl = 1.550; gfi = .90; cfi = .95; tli = .94; rmsea = .036, ic 90 % = (.031-.041), p close= 1.000, srmr = .05]. El resultado fue una escala de 18 ítems distribuidos en las cinco dimensiones originales, cada una con confiabilidad por consistencia interna alfa de Cronbach entre .66 y .78 y coeficientes omega entre .70 y .75. La confiabilidad entre evaluadores estuvo entre .67 y .88. Los alcances y limitaciones del estudio son discutidos teniendo en cuenta la importancia de contar con instrumentos de medición del involucramiento paterno, relativo al materno, que consideren las perspectivas de padres y madres en el contexto peruano.

The balance between work and family demands is one of the main challenges of contemporary parenting. However, most of the research has focused on mothers’ perspectives, with fathers’ perspectives about the links between work–family activities and father involvement, as well as the role of indirect effects, such as parenting styles, being less explored. This study aims to bridge these gaps by exploring whether work strains or gains are related to father involvement in childcare and the mediating role of parental styles, focusing on fathers’ reports. Working, married fathers of preschoolers (n = 411) self-reported about work strains and gains, parental styles, and father involvement. Structural equation modeling, using maximum-likelihood estimation, provided good fit indices. Results of the bootstrap analysis revealed how fathers’ gains indirectly increased involvement both in direct and indirect care through positive parental styles. Otherwise, fathers’ strains at work had a negative indirect effect on direct care through negative parental styles. Findings contribute to work–family interface by showing how parental styles account for mediating environmental challenges on father involvement.

(1) Background: The aim of the study was to explore how child’s characteristics (age, sex, and temperament) were associated with father’s involvement in child-related activities. In a sample of 410 bi-parental families with pre-school age children. (2) Methods: Dividing the sample into two age groups, OLS regression models were conducted for each dimension of father involvement with child characteristics as predicting variables. (3) Results: for the younger children (3 and 4 years) fathers were more involved in teaching/discipline and played with their more extroverted daughters. With older children (5 and 6 years), fathers were more involved in teaching/discipline and played when children were higher on negative-affectivity. An interaction was found with boys’ higher negative-affectivity, predicting fathers’ higher involvement in teaching and discipline. (4) Conclusions: Our results suggest that children’s characteristics have an impact on what fathers do, particularly in a dimension salient to pre-school years such as teaching/discipline. This can help build tailored empirical-sustained programs aiming to encourage and support fathers’ positive involvement.

Children acquire and develop emotional regulatory skills in the context of parent-child attachment relationships, nonetheless empirical studies have focused mainly on mother and less information is available regarding the role of both parent-child attachment relationships. Furthermore, despite its importance, there is no information regarding preschool years. This study aims to fill this gap by exploring the potential influences of both mother-child and father-child attachments on preschooler's later emotion regulation observed in the peer group. Fifty-three Portuguese nuclear families (mother, father and focal child) participated in the study; 47% of the children were boys and 53% were girls. Attachment Security was assessed at home using the Attachment Behavior Q-set when children were 3 years of age, and emotion regulation was observed in the preschool classrooms attended by the children at age 5, using the California child Q-sort to derive an Emotion Regulation Q-Scale. Results showed that the combined influence of both parent-child attachment security predicted better emotion regulation results, than did the specific contributions of each parent per se. Findings are consistent with integrative approaches that highlight the value of including both mother- and father-child attachment relationships, as well as their combined effect, when studying emotion regulation.

The increase in women’s labor market participation emphasizes the importance of understanding maternal separation anxiety, that is, the unpleasant maternal emotional state, due to the actual or anticipated short-term separation from the child. Drawing on the insights of the attachment and psychoanalytic perspectives, the Maternal Separation Anxiety Scale (MSAS) was developed to overcome existing measurement gaps. However, prior research did not replicate its original three-factor structure in the contemporary context and in other cultural settings, using large samples composed of mothers of preschool children. This study aimed to examine the factorial structure of the MSAS in a sample of 597 Portuguese mothers of children aged 5–84 months who completed the questionnaire. The exploratory factor analysis (EFA) conducted in subsample 1 revealed a four-factor structure: Maternal Negative Feelings, Beliefs about Exclusive Maternal Care, Need of Proximity, and Perceptions of Separation Benefits for Children. Confirmatory factor analyses conducted in subsample 2 revealed that the original three-factor structure revealed a poor fit, whereas the four-factor solution (obtained in the EFA) revealed an acceptable fit. As in previous studies, our findings report deviations from the original three-factor structure of the MSAS. Three of the newly identified factors seem to reflect specific sub-dimensions that originally guided item development in the MSAS, namely, maternal negative feelings, maternal attitudes about the value of exclusive maternal care, and the need of proximity with the child. The last factor appears to represent a refinement of original items pertaining to perceptions about separation effects for children.

Correlated trait–correlated method minus one was used to evaluate convergent and discriminant validity of Social Competence Behavior Evaluation questionnaire (Social Competence, Anger-Aggression, Anxiety-Withdrawal) between multiple raters. A total of 369 children (173 boys and 196 girls; Mage = 55.85, SDage = 11.54) were rated by their mothers, fathers, and teachers. Results showed more convergence between parents than parent-teacher ratings. Mother-teacher share a common view of child behavior that is not shared with father. Parents had more difficulty distinguishing internalizing and externalizing behaviors (especially fathers). Measurement invariance across child sex was explored, results imply that differences between boys and girls were not due to measure. Girls (compare to boys) were described as more social competent by their fathers and teachers, while boys as more aggressive by mothers and teachers.

Using a sample of Portuguese preschool-age children, we aimed to identify different play profiles based on teachers’ descriptions of social and non-social behaviors, as well as characterize them in terms of children’s characteristics (sex and temperament) and fathers’ parenting styles (e.g., warmth and involvement or punitive strategies). The 243 children were distributed across four profiles (identified through a two-stage cluster analysis): Solitary/Reticent, Social Rough, Social, and Social Solitary. A univariate effect was found between play profiles and children’s effortful control, as well as fathers’ punitive strategies. In addition, a significant multivariate interaction was found between child’s sex and the Solitary/Reticent and Social Rough profiles for father’s punitive strategies. In this sample, children with social play profiles seem to use diverse types of behaviors during their interactions with peers and in being adjusted within the group. As children’s early experiences with peers are a central context for healthy development, a better understating of the diversity of play profiles and its predictors is important for early interventions.

This study explores Fathers' perceptions about their level of involvement (relative to the mothers') in 5 areas: Direct Care; Indirect Care; Teaching/Discipline; Play; and Leisure outside the home. Participants were 110 bi-parental Portuguese Families. The level of the fathers' involvement desired by the mothers, child age, gender and temperament were measured as predictors of fathers' perception of his relative involvement level. Results show that according to father's it's the mother who almost always performs tasks related to Indirect Care, while in the other domains the activities are shared. Mothers' desire a greater participation of the fathers in both type of Care activities, and a lesser participation in the Play activities. Gender differences were found for Care and Play activities. Multiple Hierarquical Regression Analyses show that the better predictor for the variance in father's participation in all areas of family routines was the level desired by the mothers. Results are discussed in each domain, considering the hypotheses of the regulatory role of the mother in the fathers' level of involvement.
