Parasympathetic and sympathetic responses to the strange situation in infants and mothers from avoidant and securely attached dyads

Abstract: Vagal reactivity and salivary a-amylase (sAA) were assessed in infants (M age ¼13.55 months) and their mothers during the Strange Situation Paradigm (SSP) to investigate differences in physiological responses in a sample of insecure-avoidant and securely-attached dyads (N ¼132). Infants classified as insecure-avoidant had significantly higher vagal withdrawal during the SSP and higher sAA overall, suggesting that the avoidant attachment pattern is associated with a greater allostatic load. During separation episodes of the SSP, all mothers showed significant vagal withdrawal, suggesting greater attempts at regulation. During the last reunion, typically the most stressful episode for infants, mothers of secure infants showed greater vagal withdrawal than mothers of insecure- avoidant infants, suggesting greater attempts by these mothers at interactive repair. Results for mothers and infants supported the allostatic load theory. 2008 Wiley Periodicals, Inc. Dev Psychobiol 50: 361-376, 2008.

Parenting Stress, Parental Reactions, and Externalizing Behavior From Ages 4 to 10

Abstract: The association between parenting stress and child externalizing behavior, and the mediating role of parenting, has yielded inconsistent findings; however, the literature has typically been cross-sectional and unidirectional. In the current study the authors examined the longitudinal transactions among parenting stress, perceived negative parental reactions, and child externalizing at 4, 5, 7, and 10 years old. Models examining parent effects (parenting stress to child behavior), child effects (externalizing to parental reactions and stress), indirect effects of parental reactions, and the transactional associations among all variables, were compared. The transactional model best fit the data, and longitudinal reciprocal effects emerged between parenting stress and externalizing behavior. The mediating role of parental reactions was not supported; however, indirect effects suggest that parenting stress both is affected by and affects parent and child behavior. The complex associations among parent and child variables indicate the importance of interventions to improve the parent-child relationship and reducing parenting stress.

Will blockchain emerge as a tool to break the poverty chain in the Global South

Abstract: Just like its recent predecessors, blockchain – also known as the distributed ledger technology – is considered to have the potential to cause major economic, political and social transformations in the Global South. The visible effects of this technology are already being noted there. We present early evidence linking the use of blockchain in overcoming some economic, social and political challenges facing the Global South. The article highlights the key applications and uses of blockchain in developing countries. It demonstrates how blockchain can help promote transparency, build trust and reputation, and enhance efficiency in transactions. The article looks at opportunities and key triggers for blockchain diffusion in these countries. It also delves into challenges and obstacles that developing economies are likely to encounter in the use of blockchain.

Lactation Counseling for Mothers of Very Low Birth Weight Infants: Effect on Maternal Anxiety and Infant Intake of Human Milk

Abstract: OBJECTIVE. Although it is well documented that breastfeeding promotes health and development of very low birth weight (VLBW) infants, lactation initiation among mothers of VLBW infants is low. Mothers are anxious about the health of their children, and medical staff may be reluctant to promote breastfeeding out of concern for increasing that anxiety. Therefore, the purpose of this study was to examine whether mothers of VLBW infants who initially planned to formula feed were different in terms of their level of anxiety and maternal stress compared with mothers who had planned to breastfeed their infants. The aims of this study were to (1) determine whether counseling mothers of VLBW infants who had initially planned to formula feed on the benefits of breast milk would increase their stress and anxiety levels, (2) assess whether mothers who initially had not planned to breastfeed changed their plans after counseling to provide breast milk, and (3) measure the amount of breast milk expressed by mothers who initially planned to formula feed. Their results were compared with those of mothers of VLBW infants who initially planned to breastfeed. METHODS. Initial plan to breastfeed (initial breastfeed group [IBG]; n = 115) or formula feed (initial formula feed group [IFG]; n = 81) was determined before counseling. All participants received counseling on infant health benefits, collection and storage of breast milk, and breast pump procurement. Maternal anxiety was measured using the State-Trait Anxiety Inventory (STAI), which was administered to mothers before and after counseling and every 2 weeks until infant discharge. Maternal stress was measured after counseling with the Parental Stressor Scale: NICU. Infant breast milk intake was measured throughout hospitalization. An exit questionnaire that pertained to the perceived benefits and efforts of expressing milk was administered close to the time of infant discharge. RESULTS. After lactation counseling, 100% of the IBG and 85% of the IFG initiated breast milk expression (used the electric breast pump in the hospital) for a total lactation initiation rate of 94%. After adjustment for the mothers who initiated milk expression but did not provide any breast milk, the lactation initiation rate for the entire group was 84%. Non-Hispanic black mothers and Non-Hispanic white mothers initiated milk expression at similarly high rates (95% vs 93%). Also, milk expression initiation was similar for low-income and non–low-income mothers (95% vs 92%). IFG and IBG STAI and Parental Stressor Scale: NICU scores were not significantly different, and there were no significant differences between groups in the change in anxiety after counseling. In addition, the mean difference scores (after counseling − before counseling) for STAI anxiety “state” were not significantly different between groups, even when controlling for “trait” anxiety. State anxiety declined during the first 6 weeks of infant hospitalization in a similar manner for both groups. Maternal trait but not state anxiety scores were inversely correlated with total infant breast milk intake. Breast milk intake (mL/kg per day) was greater in the infants of mothers in the IBG compared with the IFG at each week during the first month and for their entire hospital stay. Infant breast milk intake increased from weeks 1 to 3 in both groups and continued to rise in the fourth week for the IBG. However, breast milk intake declined at week 4 for the IFG. IBG infants received breast milk for 83% of the total fed hospital days (days that feedings were given) compared with 44% of total fed days for the IFG. The proportion of enteral intake that was breast milk was also greater for the IBG compared with IFG during the first 4 weeks and for the total hospitalization. However, the mothers in IFG were able to provide at least 50% of their infants' enteral intake for the first 3 weeks, 48.8% for the fourth week, and 32.8% of the enteral intake for the entire hospitalization. Infants of low-income women received significantly lower amounts of breast milk than did infants of non–low-income mothers. Race and income accounted for 36% of the variance in breast milk intake. Of the 184 mothers who initiated breast milk expression, 72 (39%) completed the exit questionnaire. Infant health benefits were the most common reasons cited by both groups for expressing milk. The most common reasons that both groups reported for ceasing milk expression were (1) low milk supply, (2) returning to work or school, and (3) inability to pump as often as needed. Almost all of the mothers reported that pumping was worth the effort (IBG 100%, IFG 87%), and 100% said that they were glad that the staff helped them with milk expression. CONCLUSION. Counseling mothers of VLBW infants increases the incidence of lactation initiation and breast milk feeding without increasing maternal stress and anxiety.

Influence of perceived coaching behaviors on burnout and competitive anxiety in female college athletes

Abstract: The focus of this study is on burnout experienced by athletes and coaches, and particularly on how athletes' perceptions of their coach's behavior and communication style may relate to levels of burnout and anxiety experienced by athletes. A modified version of the Maslach Burnout Inventory was used to measure burnout in coaches and the Eades Athletic Burnout Inventory was used to measure six components of burnout in athletes. Three multivariate analyses supported links in the study model. Coach burnout was significantly related to perceived coaching styles/behavior, perceived coaching styles/behavior was predictive of athlete burnout, and athlete anxiety and athlete burnout were significantly related. Interestingly, perceived coaching style/behavior was not a significant predictor of athlete anxiety. The results are discussed in relation to psychometric issues in the measure of bumout and coaching behavior as well as the need for sport psychology researchers to examine burnout from within a soci...
