Relationship between perceptions of classroom climate and institutional goal structures and student motivation,engagement and intention to persist in college

Disengagement and a lack of motivation have been found to be the major reasons for student drop out from higher education. In order to broaden our understanding of institutional and personal factors associated with intention to complete a college degree, this investigation examined the relationship between students’ perceptions of classroom climate and institutional goal structures and their motivational orientation, engagement and intention to persist in college. Data was collected from first-year students (N = 1778) enrolled in an institution of higher education near Bangkok, Thailand. The results indicate that perceptions of classroom climate and institutional goal structures have significant associations with students’ motivational orientations and levels of engagement and contribute to intention to persist in college.     

Session - 6 December 19, 2007 Respiratory signal transduction mechanisms

In a prospective study of 47 patients of subclinical hepatic encephalopathy in cirrhosis of liver, aged between 23 and 60 years, 49% showed Helicobacter pylori positivity by rapid urease test. The baseline characters of patients (mean age, serum creatinine, sereum albumin, serum bilirubin, prothrombin time) were similar among patients with and without Helicobacter infection in all the patients. There was no statistically significant difference in blood ammonia levels in either group of patients. Blood ammonia values showed good correlation with the functional state of liver function but they did not show statistically significant difference between two groups of patients in any of Child Pugh classes. It is concluded that Helicobacter pylori does not contribute significantly to blood ammonia levels and the severity of hepatic encephalopathy.     

RELATIONSHIPS BETWEEN PSYCHOLOGICAL WELLBEING OF THAI COLLEGE STUDENTS,GOAL ORIENTATIONS,AND GENDER

This paper examined the direct and interaction effects of students’ learning and performance‐avoidance goal orientations on their psychological wellbeing and a moderating role of students’ gender in these relationships. Using 564 self‐reports of freshman college students in a Thai university, we found students’ psychological wellbeing to be positively related to their learning goal orientation and negatively related to their performance‐avoidance goal orientation. Additionally, the negative relationship between students’ performance‐avoidance goal orientation and psychological wellbeing was stronger for men than women. Lastly, differences in students’ psychological wellbeing between men and women became more pronounced with increases in learning goal orientation for students with low levels of performance‐avoidance goal orientation, but not for students with high levels of performance‐avoidance goal orientation. These findings were obtained after controlling for students’ grade point average and academic program.     

Study of Serum Homocysteine, Folic Acid and Vitamin B12 in Patients with Preeclampsia

The present study was carried out to evaluate the occurrence of association between homocysteine, folic acid and vitamin B(12) in patients with preeclampsia. Fifty preeclamptic patients from gynecology ward were studied for estimation of serum homocysteine, folic acid and vitamin B(12) over a period of October 2007 to June 2010. Serum homocysteine and folic acid, and vitamin B(12) were determined by means of Immulite 1000 analyzer. The statistical analysis of study group of preeclampsia compared with normotensive control group, showed significant alterations in serum homocysteine, folic acid and vitamin B(12) concentrations in preeclampsia. Inverse association between serum homocysteine and folic acid, and vitamin B(12) levels were observed in preeclampsia. The present study found hyperhomocysteinemia and deficiency of folic acid and vitamin B(12) along with increased blood pressure as a risk factor for cardiovascular disease (CVD) in preeclampsia.
