An integrative cultural view of achievement motivation: Parental and classroom predictors of children's goal orientations when learning mathematics in Korea.

Our goal was to identify how students' perceptions of their parents shape the kind and degree of motivational goal orientations that they adopt in their mathematics classroom, broadening the application of achievement goal orientation theory and self-determination theory to students in Korea. Two groups of students participated, one from a middle school located in a large metropolitan area and the other from a small city high school. Multisample path analysis of data from both groups revealed that Korean students' different goal orientations were predicted by their perceptions of parental goals and motivating styles and by their perceptions of classroom goal structures, mediated by different types of self-regulated motivations. Particularly interesting was the finding that Korean students' degree of mastery goal adoption was associated mostly with identified regulation, not with intrinsic motivation, and predicted by their perceptions of their parents' motivating styles, both autonomy supportive and controlling, in addition to perceptions of parents' mastery goals. Perceptions of classroom goals were stronger predictors of students' own goals than were perceptions of parents' goals and motivating styles. We offer an integration of self-determination theory and achievement goal theory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

MEK6 Overexpression Exacerbates Fat Accumulation and Inflammatory Cytokines in High-Fat Diet-Induced Obesity

Obesity is a state of abnormal fat accumulation caused by an energy imbalance potentially caused by changes in multiple factors. MEK6 engages in cell growth, such as inflammation and apoptosis, as one of the MAPK signaling pathways. The MEK6 gene was found to be related to RMR, a gene associated with obesity. Because only a few studies have investigated the correlation between MEK6 and obesity or the relevant mechanisms, we conducted an experiment using a Tg^MEK6 model with MEK6 overexpression with non-Tg and chow diet as the control to determine changes in lipid metabolism in plasma, liver, and adipose tissue after a 15-week high-fat diet (HFD). MEK6 overexpression in the Tg^MEK6 model significantly increased body weight and plasma triglyceride and total cholesterol levels. p38 activity declined in the liver and adipose tissues and lowered lipolysis, oxidation, and thermogenesis levels, contributing to decreased energy consumption. In the liver, lipid formation and accumulation increased, and in adipose, adipogenesis and hypertrophy increased. The adiponectin/leptin ratio significantly declined in plasma and adipose tissue of the Tg^MEK6 group following MEK6 expression and the HFD, indicating the role of MEK6 expression in adipokine regulation. Plasma and bone-marrow-derived macrophages (BMDM) of the Tg^MEK6 group increased MEK6 expression-dependent secretion of pro-inflammatory cytokines but decreased levels of anti-inflammatory cytokines, further exacerbating the results exhibited by the diet-induced obesity group. In conclusion, this study demonstrated the synergistic effect of MEK6 with HFD in fat accumulation by significantly inhibiting the mechanisms of lipolysis in the adipose and M2 associated cytokines secretion in the BMDM.
