The impacts of public interventions: An examination of the forestry sector

This article measures welfare and distributive effects of public market interventions in forestry. These interventions represent both the demand (Jones Act shipping restrictions and minimum wage restrictions) and supply (state forest practice acts, forest incentives payments, taxes and public land management) sides of the market. The authors evaluate how well these programs promote the three standard economic justifications for market intervention: market failure, distributive justice, and stabilization. Their results indicate that, with the single exception of Timber Mart South (a government-sponsored price-reporting service), all market interventions fail to accomplish their efficiency and distributive objectives. Furthermore, the authors find that targeted regulatory programs (such as State Forest Practice Acts) have small impacts when compared to effects of taxation and public ownership.

Doing homebirth like a man? Constructions of masculinity in South African men’s narratives of homebirth

The intersections between homebirth and masculine identities have not been widely explored. In this paper, we focus on the construction/contestation of masculinity in South African men’s narratives of planning and experiencing homebirth. Drawing on 20 interviews conducted with a sample of 5 men and couples in 2013–2014, a narrative analysis found men constructed ideal masculinities and ways of being a man in relation to homebirth. The paper focuses on the multiple representations of masculinity constructed in men’s talk about homebirth and traces their efforts to articulate a masculine perspective of birth. Men grappled with the meanings of ‘being there’ as a man during labour/birth and articulated alternative modes of being a man that valued and accommodated relationality, passivity and containment. Men thus articulated ways of being present and passive during homebirth that challenged normative constructions of masculinity. The notion of selfless masculinity emerged as a key masculine ideal in which giving and service during birth was constructed as integral to being a good father and man. However, competing forms of normative masculinity constructed in men’s narratives meant gender tensions remained in the continued salience of traditional masculine meta-narratives, such as being the ‘breadwinner’.     

The Developmental Significance of Adolescent Romantic Relationships: Parent and Peer Predictors of Engagement and Quality at Age 15

From a longitudinal sample (n = 957; 49.9% male; 77.3% White/non-Hispanic) of participants studied from infancy through age 15, adolescents’ depth of engagement in, and quality of romantic relationships were predicted from early and contemporaneous parent–child interactive quality and peer social competence. High quality maternal parenting and peer experiences prior to and during adolescence tended to be negatively associated with the depth of engagement in this domain for the full sample, yet positively associated with the quality of adolescents’ romantic relationships for the sub-set of individuals currently dating at age 15. Results reconcile contrasting views of the origins of romantic relationship engagement and quality and the positive versus negative developmental salience of romantic relationships in adolescence.
