    Motivational drivers and emotions that students experience play an important role in the process of learning a new language (L2). This has been recognised by researchers and educators, and extensive research has been conducted in recent decades to examine the psychological and emotional factors involved in L2 learning. However, two ubiquitous epistemic emotions, namely, boredom and curiosity, remain underexplored in the L2 research literature. This study addresses this gap. It performed a series of statistical tests to examine the relationship between these two epistemic emotions and L2 motivation. Specifically, it assessed whether epistemic curiosity plays a mediating role in the nexus of L2 motivation, epistemic curiosity, and epistemic boredom. Data were collected from adolescent learners of English in China (N = 312). The findings from the correlation analysis indicated that epistemic boredom had statistically significant negative relationships with epistemic curiosity and L2 motivation, except for the ought-to L2 self variable, where the relationship was not statistically significant. Conversely, epistemic curiosity had a positive and statistically significant relationship with L2 motivation, except for the ought-to L2 self variable, where the relationship was not statistically significant. Next, the path analysis examined the influence of L2 motivation on epistemic boredom without considering the mediating effect of epistemic curiosity. Its findings indicated that epistemic boredom had a statistically significant negative relationship with the general motivation/attitude and general motivation/effort variables. The subsequent path analysis, which focused solely on two goal-oriented L2 motivation constructs from the Gardnerian framework, detected the mediating role of epistemic curiosity. Some pedagogical implications are drawn from these findings.

    INTRODUCTION: Breast milk fatty acids play a major role in infant development. However, no data have compared the breast milk composition of different ethnic groups living in the same environment. We aimed to (i) investigate breast milk fatty acid composition of three ethnic groups in Singapore and (ii) determine dietary fatty acid patterns in these groups and any association with breast milk fatty acid composition.

    MATERIALS AND METHODS: This was a prospective study conducted at a tertiary hospital in Singapore. Healthy pregnant women with the intention to breastfeed were recruited. Diet profile was studied using a standard validated 3-day food diary. Breast milk was collected from mothers at 1 to 2 weeks and 6 to 8 weeks postnatally. Agilent gas chromatograph (6870N) equipped with a mass spectrometer (5975) and an automatic liquid sampler (ALS) system with a split mode was used for analysis.

    RESULTS: Seventy-two breast milk samples were obtained from 52 subjects. Analysis showed that breast milk ETA (Eicosatetraenoic acid) and ETA:EA (Eicosatrienoic acid) ratio were significantly different among the races (P = 0.031 and P = 0.020), with ETA being the highest among Indians and the lowest among Malays. Docosahexaenoic acid was significantly higher among Chinese compared to Indians and Malays. No difference was demonstrated in n3 and n6 levels in the food diet analysis among the 3 ethnic groups.

    CONCLUSIONS: Differences exist in breast milk fatty acid composition in different ethnic groups in the same region, although no difference was demonstrated in the diet analysis. Factors other than maternal diet may play a role in breast milk fatty acid composition.
