Feeding upon awakening in breastfeeding and bottlefeeding mothers does not affect the awakening cortisol response

An acute breastfeeding stimulus is generally followed by a transient decrease in cortisol levels in mothers. It is currently not clear whether breastfeeding upon waking up would affect the awakening cortisol response (ACR), a significant increase in salivary cortisol levels occurring within 30-45 min after awakening. In the present study, we measured the amplitude and stability of the ACR in response to infant feeding in women who were exclusively bottle-feeding (n = 16), or breastfeeding (n = 13) or feeding their child solid food (n = 12). The results show that the type of infant feeding did not affect the amplitude and stability of the ACR. Given that the ACR has been reported to reflect physical and psychological well-being, our finding that infant feeding upon waking up might not be a confounding factor in ACR studies on the postpartum population represents valuable methodological information.     

Sex differences in English language acculturation and learning strategies among Vietnamese adults aged 40 and over in the United States

This study examines sex differences in English language acculturation and learning strategies among older Vietnamese in the United States in a nationwide probability sample. Data of this study came from the Southeast Asian Refugee Self-Sufficient Study (1982). The results reveal that older Vietnamese women had more problems with their English language than older Vietnamese men. In addition, the Vietnamese men were more likely to use various learning strategies to improve their English skills than the women.

Measuring stress responses in postpartum mothers: perspectives from studies in human and animal populations

Reduced hypothalamic-pituitary-adrenal (HPA) responses to stress during the last week of pregnancy and lactation have been consistently observed in rat studies. Several contributing factors have been proposed for this phenomenon in lactation, including the suckling stimulus from the pups, hormones (oxytocin and prolactin) and opioids, a decrease in the ability of noradrenaline to potentiate hypothalamic responses and changes in pituitary responsiveness to ACTH secretagogues (AVP and CRF). In contrast to this vast literature using the rat model, only few studies have addressed this issue in the human population. The consensus is that women engaging in breastfeeding activities exhibit reduced anxiety, although the reductions in neuroendocrine and autonomic responses to stressors are variable, in part because of the different nature of the stressors used. Further work is required to investigate how additional factors, such as maternal parity or emotional salience of the stressor can affect stress responsiveness in postpartum women. Here, we review first the findings regarding stress responsiveness during lactation in both rat and human studies, and then discuss potential research avenues and methodological issues that could be the lead to future research protocols in human subjects. Knowing the reciprocal relationship in the mother-infant dyad, it is clear that investigation of the mechanisms regulating stress responses and mental health in postpartum mothers can only be beneficial to the development of the infant.     

Teacher commitment: a comparative study of Malaysian ethnic groups in three types of primary schools

Commitment is a complex attitude that is potentially influenced by the nature of the groups and is contingent on the context in which an individual functions. Thus, different sociocultural environments will prescribe different imperatives for individuals’ or groups’ attitudes toward their work, particularly teachers’ commitment in a multi-ethnic educational setting. However, previous teacher commitment studies have predominantly been applied to single-sample studies in a multiracial Malaysian context. Therefore, this study attempts to compare the teacher commitment levels and the four dimensions of teacher commitment across Malay, Chinese and Indian teachers who are the dominant ethnicities in three different types of Malaysian primary schools. Questionnaires were administered to 1,154 primary school teachers in Penang, and the obtained data were analysed using AMOS 20.0 and SPSS 20.0. The findings revealed nonsignificant differences for commitment to school, commitment to students, commitment to teaching and commitment to profession for any pair of ethnic groups. Limitations and suggestions for future studies are discussed.
