Family language policy and bilingual parenting

Abstract: While the study of bilingual development among children dates back roughly a century (Leopold 1939–49; Ronjat 19131), a defined research focus on family language policy is relatively new. Family language policy (FLP) links studies of child language acquisition and early second language learning and bilingualism with the field of language policy. FLP examines language policy in relation to language use and language choice within the home among family members (King, Fogle & Logan-Terry 2008). This line of inquiry differs from more psycholinguistically oriented investigations of bilingualism; rather than targeting the child, the emphasis of FLP is on the balance between and use of languages within the family unit. Thus, FLP addresses child language learning and use as functions of parental ideologies, decision-making and strategies concerning languages and literacies, as well as the broader social and cultural context of family life. The interdisciplinary field of FLP draws from anthropology (and work on language socialization in particular) and sociolinguistics (specifically, discourse analysis) while also incorporating traditional psychological approaches to bilingualism. While FLP is still coalescing as a field, there have already been several notable shifts. The first of these is increased focus on and intentional inclusion of a broader, more diverse range of family types, languages, and social contexts. While FLP research has tended to document twoparent, middle-class homes in which children are acquiring more than one European language (Métraux 1965; Lanza 1992), current work explores how these processes play out within minority language and/or non-traditional (e.g. adoptive, single-parent) families in transnational or diasporic contexts (Canagarajah 2008). Second, the last ten years of FLP research have been marked by increased emphasis on the family as a dynamic system, including the importance of child agency and identity choices, both enacted through language (Okita 2001; Gafaranga 2010). Third, current work in FLP gives greater emphasis to trilingualism or multilingualism, with a growing number of studies examining how families manage multiple languages (Lanza & Svendsen 2007; Curdt-Christiansen 2009).

Apparent inability of channel catfish to utilize dietary mono- and disaccharides as energy sources.

Abstract: Purified diets containing equivalent amounts of glucose, maltose, fructose, sucrose, corn starch and dextrin were fed to fingerling channel catfish (Icatalurus punctatus) to compare the growth responses to these various carbohydrates. The best growth response was achieved with dextrin and the next best with corn starch. Fish grew at the same rate when glucose, maltose or sucrose was the only dietary carbohydrate source. Dietary fructose resulted in the lowest growth rate. Feed efficiency and percent retained energy values followed the same pattern as growth rates. These data suggest that the catfish is apparently unable to utilize dietary mono- and disaccharides as energy sources. Oral carbohydrate tolerance tests using glucose, maltose, fructose, sucrose and dextrin were conducted with larger channel catfish. Oral glucose and maltose resulted in a persistent hyperglycemia indicative of a diabetic-like status. Fructose appeared to be poorly absorbed from the intestinal tract and did not appear to be converted to glucose. Oral administration of sucrose was followed by a gradual increase in plasma glucose, with no detectable fructose being absorbed until the 6-h period. Oral dextrin resulted in less than a two-fold increase in plasma glucose, which remained constant from 2 to 4 h after administration and then declined. These observations are consistent with the hypothesis that certain fishes, including the channel catfish, resemble diabetic animals by having insufficient insulin for maximum carbohydrate utilization.

Digestible and metabolizable energy of crude glycerol for growing pigs.

Abstract: The apparent DE and ME values of crude glycerol for growing pigs were determined in 5 experiments using crude glycerol (86.95% glycerol) from a biodiesel production facility, which used soybean oil as the initial feedstock. Dietary treatments were 0, 5, or 10% glycerol addition to basal diets in Exp. 1; 0, 5, 10, or 20% glycerol addition to basal diets in Exp. 2; and 0 and 10% crude glycerol addition to the basal diets in Exp. 3, 4, and 5. Each diet was fed twice daily to pigs in individual metabolism crates. After a 10-d ad- justment period, a 5-d balance trial was conducted. Dur- ing the collection period, feces and urine were collected separately after each meal and stored at 0°C until anal-
