SUMMARY: We developed a theoretical model that describes how aggression among unacquainted pigs is a function of group size. As the number of potential competitors increases, more individuals will benefit from not getting involved in costly fights. To verify predictions from this model, we compared aggression among unacquainted, weaned pigs in three group sizes (6, 12 and 24 pigs). There were significantly more fights per individual in groups of six and 12 pigs than in groups of 24 pigs, and the proportion of pigs not participating in fights was significantly higher in the largest group. We conclude that pigs are able to alter their behaviour according to how the actual competitive situation changes with group size.

SUMMARY: Currently, 10-15% of women giving birth suffer from symptoms of postpartum depression. Due to a lack of knowledge of this condition and the stigma associated with it, as well as few treatment options, a large proportion of postpartum women with depression remain untreated. Internet-based interventions have been found effective in treating depression, anxiety, phobias, and addictions. Hence, we developed such program (“Mamma Mia”) with the aim of reducing the risk for postpartum depression and enhance subjective well-being. Mamma Mia is based on positive psychology, metacognitive therapy, and couples therapy. It starts in gestational week 22, and lasts until 6 months after birth. During pregnancy, Mamma Mia is delivered weekly (every Monday). After birth, Mamma Mia is delivered three times per week for six weeks. The remaining weeks, the program is delivered more sporadically. In total, Mamma Mia consists of 44 sessions. The program is individualized, interactive, and tunneled (ie, the user is guided through the program in a pre-determined manner).

CULTURAL REFERENCE: "Mamma Mia" is a song recorded by the Swedish pop group ABBA. The song's name is derived from Italian, where it is an interjection used in situations of surprise, anguish, or excitement.

SUMMARY: This article explores the evolving relationship between curriculum design, teacher perceptions, and the lived experience of students participating in an international programme of study within a U.K. university business school. The article illustrates the challenges inherent in supporting cross-cultural learning within diverse cohorts and explores the use of reflective learning strategies as a means of promoting cross-cultural understanding. It concludes with a discussion about the positioning of university curricula as international spaces within local contexts and questions the degree to which implicit pedagogical norms support inclusivity.

CULTURAL REFERENCE: "Knowing Me, Knowing You" is a hit single recorded by Swedish pop group ABBA. The song is featured on the group's album Arrival, and also on the compilation Gold: Greatest Hits.
