Sommario/riassunto |
|
Stevioside is one of the naturally occurring sweeteners, belonging to the diterpene glycoside family, which can be widely applied in food, drinks, medicine and consumer chemicals. It is a good dietary supplement, being non-calorific, thermally stable, non-toxic, with a sugar-like taste profile, and suitable for diabetics, phenylketonuria patients and the obese. It is also non-fermentable, and exhibits anti-carcinogenic, antioxidant and anti-hyperglycemic properties. Stevioside tastes about 300 times sweeter than 0.4% sucrose solution. Thus, it offers a reasonably rare combination of health |

Sommario/riassunto |
|
Wie sollen pädagogische Fachkräfte in Kitas mitdem Thema Geschlecht umgehen? Vor der Folie von frühpädagogischen Geschlechterdebatten bietet diese Studie einen empirischen Einblick in Geschlechterkonstruktionen von Kindern, Fachkräften und Eltern im Alltag einer Kindertageseinrichtung. Des Weiteren werden theoretische und empirische Leerstellen einer frühpädagogischen Debatte um Geschlecht aufgezeigt, die entstehen, wenn diese lediglich vor der Folie von Geschlechtergerechtigkeit mit dem Ziel der Verbesserung von Chancengleichheit geführt wird. |
Die Studie gewährt viel mehr empirischen Einblick in die Geschlechterkonstruktionen von Fachkräften, Kindern und Eltern. jugendhilfereport, 01.2017 Es ergeben sich diverse Anknüpfungspunkte für weitere Studien, um das beobachtete milieuspezifische Einzelsetting tiefergehend mit strukturellen Variablen zu kontextualisieren.
