This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept. 相似文献

Early identification of patients with acute myocardial infarction is of prime importance due to the associated very high mortality.
Only 22% of the patients presenting at emergency cardiology care with chest pain have coronary disease. A number of biochemical
tests like CKMB and Troponin-T/I have been introduced for early detection of the coronary syndrome (ACS). Ischemia modified
albumin (IMA) has been recently introduced as a marker of myocardial ischemia. We estimated serum IMA in four sequential samples
from 25 patients admitted to ICCU. Twenty five healthy volunteers formed the control group from which the normal range was
derived. IMA was significantly raised in ischemia patients than in controls as well as compared to the patients who did not
have cardiac ischemia. IMA demonstrated good discrimination between the ischemic and the non-ischemic patients with an Odds
Ratio of 16.9 (6.29–46.87) than CKMB which showed an Odds Ratio of 2.07 (1.18–6.08). Sensitivity and specificity of IMA for
the detection of ACS was 78.0% and 82.7% compared to 58.0% and 60.0%, respectively for the CK-MB assay. The area under the
ROC curve of IMA for ischemic v/s non-ischemic patients was 0.834. IMA appears to be developing into a new and very potent
marker, of cardiac ischemia. 相似文献

Ensuring quality of laboratory services is the need of the hour in the field of health care. Keeping in mind the revolution
ushered by six sigma concept in corporate world, health care sector may reap the benefits of the same. Six sigma provides
a general methodology to describe performance on sigma scale. We aimed to gauge our laboratory performance by sigma metrics.
Internal quality control (QC) data was analyzed retrospectively over a period of 6 months from July 2009 to December 2009.
Laboratory mean, standard deviation and coefficient of variation were calculated for all the parameters. Sigma was calculated
for both the levels of internal QC. Satisfactory sigma values (>6) were elicited for creatinine, triglycerides, SGOT, CPK-Total
and Amylase. Blood urea performed poorly on the sigma scale with sigma <3. The findings of our exercise emphasize the need
for detailed evaluation and adoption of ameliorative measures in order to effectuate six sigma standards for all the analytical
processes. 相似文献

This study explored pre-service secondary science teachers’ perceptions of classroom emotional climate in the context of the Bhutanese macro-social policy of Gross National Happiness. Drawing upon sociological perspectives of human emotions and using Interaction Ritual Theory this study investigated how pre-service science teachers may be supported in their professional development. It was a multi-method study involving video and audio recordings of teaching episodes supported by interviews and the researcher’s diary. Students also registered their perceptions of the emotional climate of their classroom at 3-minute intervals using audience response technology. In this way, emotional events were identified for video analysis. The findings of this study highlighted that the activities pre-service teachers engaged in matter to them. Positive emotional climate was identified in activities involving students’ presentations using video clips and models, coteaching, and interactive whole class discussions. Decreases in emotional climate were identified during formal lectures and when unprepared presenters led presentations. Emotions such as frustration and disappointment characterized classes with negative emotional climate. The enabling conditions to sustain a positive emotional climate are identified. Implications for sustaining macro-social policy about Gross National Happiness are considered in light of the climate that develops in science teacher education classes. 相似文献

Thyroid hormones regulate the renal hemodynamics and basal metabolic rate of most cells. This hospital-based case-control
study was done to evaluate the changes in biochemical markers of liver and kidney function in hypothyroid subjects before
and after treatment. The study included 176 subjects randomly selected from Thyroid clinics. Serum T3, T4, TSH, Liver and Kidney Function tests were analysed using standard kits. Forty-six hypothyroid patients were re-evaluated
6 weeks after thyroxine substitution therapy. Hypothyroid subjects (n=80) showed significantly raised serum creatinine and
uric acid levels as compared to euthyroid subjects (n=96). After 6 weeks of thyroxine replacement, serum creatinine and uric
acid decreased significantly and were comparable to euthyroid group. A positive correlation of ALT, AST, uric acid, protein
and albumin with TSH levels (p<0.05) and negative correlation of serum T4 levels with ALT, AST, proteins (p<0.05) was observed in the hypothyroid group. Hypothyroidism results in reversible impairment
of hepatorenal function. 相似文献

The nature of the dyslipidemia associated with diabetes mellitus is complex and is the major risk factor for atherosclerosis and coronary artery disease. Aim of this study was to assess the effect of glycemic control, achieved by metformin, glibenclamide and insulin, on lipid profile in type 2 diabetic patients. One hundred and sixty-five type 2 diabetes mellitus patients were classified into good glycemic control (Group I) and poor glycemic control (Group II) on the basis of their blood HbA1c values. The Group II was characterized with high serum triglyceride (190.46 ± 15.20 mg/dl), total cholesterol (175.3 ± 6.31 mg/dl) as well as high LDL-cholesterol (109.0 ± 5.88 mg/dl). Significant correlations were evident between HbA1c and dyslipidemia, particularly serum TG (r = 0.28, P < 0.05), and between HbA1c and total cholesterol (r = 0.310, P < 0.05). Better glycemic control and improved dyslipidemia were observed in patients on combination therapy of metformin plus glibenclamide. 相似文献
