Sexual differences in parental feeding effort during the nestling period of the White-headed Marsh-Tyrant (Arundinicola leucocephala)

Parental effort may influence the fitness and survivorship of adult birds and their offspring from one breeding season to the next. Although much is known about parental feeding effort in tyrant flycatchers, many species remain understudied. In this study, I examined parental feeding effort of the White-headed Marsh-Tyrant (Awndinicola leucocephala) at a pond in southeastern Brazil. I conducted 10.3 hrs of observations from two locations: a high place with all view of the whole pond, that allowed me to observe flight distances of parents hunting for prey; and from near the nest to observe frequency of visits to the nest. The female marsh-tyrant flew farther while hunting prey and made more visits to the nest than did the male. The adults (mainly the female) provided a variety of terrestrial and aquatic arthropods to the nestlings. Additionally, parents removed fecal sacs from the nest and nestlings eliminated arthropod remains from the nest, the first records of nest sanitation activities by this species. Nonexclusive hypotheses that may explain the lower level of parental care provided by the male include: higher predation risk due its more conspicuous plumage, commitment of male to territory defense, and its selfish behavior influenced by indirect genotype fitness inherited by the offspring. © The Neotropical Ornithological Society.

The importance of parental involvement in swimming lessons for person with disability

The Ecolological Theory of Human Development proposed by Urie Bronfenbrenner assumes that the activities and people involved in an evironment are essential to stimulate the aquisition of new abilities . Analyze the strategy of parent’s presence with their children in a swimming class for PWD during the teaching process. Also, verify the parent’s views on this experience and the participation of their child during practice. It is a qualitative and action-research. To collect data was utilized observation during to analyse the activities developed in a swimming class for PWD, on the presence of parents with their children. A semi-structured interview was used to analyse the perception parents after the experience of the classroom. Analysis of activities and the interview were based on the assumption of Bronfenbrenner (1996). It was found that 100% of the parents rated the positive experience of being with their children in the pool. We found that only 25% of parents reported that had entered the pool to play with their children. We emphasize that 75% had never entered in the water with their children, whether because of fear, lack of opportunity or not knowing how to swim. The proposal of parents’ participation in the swimming class with the PWD generated a favorable environment for development the activities. Parents identified the improvement, the potential and difficulties of PWD.

Assessment of the effects of a parental intervention with mothers of children with internalizing problems

The present study assesses the effects of a semi-structured intervention held exclusively with mothers and its effects on internalizing problems, social skills of children, and positive and negative parenting practices. The single subject experimental design with three participants was adopted. The three mothers had, in baseline, children diagnosed with internalizing and externalizing problems. The instruments used were CBCL, RE-HSE-P, QRSH-Pais and PHQ-9, they were performed in baseline, pre-test, post-test, and follow-up assessments. The intervention held is characterized as semi-structured for it promotes the development of parental practices that are considered positive by the literature on behavior problems, however, contingently to the difficulties and demands of each case. The number of sessions performed for each case was 14, 15 and 17, which lasted about two hours each. The data were analyzed according to the instruments' norms and under the perspective of each singular case. The results found include remission of internalizing problems, increase in frequency of the children's social skills, increase in frequency of positive parental practices, and decrease in variability of negative parental practices. All the improvements were maintained on the six months follow-up, with the exception of variability on the negative parental practices of one client. Results are discussed in a context of mental health promotion and indicate the need for strategies to prevent internalizing problems in children.
