Using Word Expert Strategy in Teaching Writing of First Grade at SMA Guppi Gowa

After several meetings, this research found out that the use of Word Expert Strategy is significantly effective to improve the students’ skill especially in writing. There was a significant difference between students post-test in experimental class and controlled class. The mean score of post-test (3.69) in experimental class was greater than the mean score of post-test (2.98) in controlled class from t-test. The mean score of pre-test for experimental class (2.56) and the mean score of pre-test for controlled class (2.51). The researcher found that the value of t-test (28,4) was greater than the t-table (2.042) at the level of significance 0.05 with the degree of freedom (df) = 38

Effect of glucocorticoid status on clock gene expression in components of the hypothalamic-pituitary-adrenal axis

This thesis explores the role of glucocorticoids in entraining the rhythmicity of clock gene expression in components of the hypothalamic-pituitary-adrenal (HPA) axis, specifically the paraventricular nucleus (PVN) of the hypothalamus and the anterior pituitary. Physiological and behavioral circadian rhythms rely on molecular oscillators inside cells of living organisms. Rhythmic expression of associated clock genes is dependent on the hypothalamic suprachiasmatic nucleus (SCN), which is synchronized to the light/dark cycle with an intrinsic rhythm near 24 hours. Extra-SCN brain regions and peripheral tissues in the body have been shown to have molecular clocks; interestingly, the SCN has sparse direct neural input in these regions. Previous research has indicated that glucocorticoids (CORT) are able to entrain clock gene rhythmicity in peripheral tissues, suggesting the SCN may synchronize peripheral clocks through a diurnal expression of CORT. Little work has been done to explore this possible mechanism of entrainment in the brain but has been characterized in periphery where CORT has been shown to cause a phase shift, induce, or abolish clock gene expression in tissues such as liver and kidney. This thesis characterizes clock gene expression in response to three different CORT profiles: antiphasic CORT treated, phasic CORT treated, and vehicle treated in adrenalectomized rats. We found that expression of clock genes Per1 and Per2 varied with CORT treatment in both the PVN and anterior pituitary, but also that CORT influenced genes differently in the two regions. The results suggest that CORT may have a permissive effect in the periphery, necessary for clock gene expression, but has an entraining effect in the brain. This study was an important step in understanding the role of CORT in HPA axis regulation and disruption. Such disruptions and dysregulation of the HPA have been observed in numerous conditions such as Posttraumatic Stress Disorder, Major Depressive Disorder, and sleep disorders

An Analysis of Primate Behavioral Responses to Environmental Change: An Anthropological and Neurobiological Approach

This thesis explores the relationship between stress, measured by glucocorticoid levels, and parasites in primate taxa to evaluate physiological and behavioral responses to humaninduced and environmental change. By conducting an in-depth literature review, data was collected from relevant studies and compared in novel ways to try and create a primate behavioral template. Fragmented and disturbed habitats were compared to intact environments. In general, across taxa primates living in anthropogenically disturbed sites exhibited elevated parasite loads and glucocorticoid levels, as was expected. Notable exceptions to this trend indicate that a more detailed consideration of the kind of anthropogenic influence primates are experiencing in an important factor. In disturbed sites, reduced food availability, increased population, and increased terrestriality all contributed to the risk of parasite infection. Where these indicators are present, there is also a high likelihood of observing chronically elevated levels of glucocorticoids. However, if resources are supplemented, either through human provisioning or crop raiding, elevated glucocorticoids is less likely. In these situations there may be more parasite diversity, but not necessarily a rise in density or degree of infection. These results indicate that parasite measures coupled with glucocorticoid analysis is an important and novel method for monitoring the health of primates and particularly their responses to environmental change. Such analyses may also facilitate conservation efforts

The concept of historical time in early childhood education: theoretical, methodological approaches and practice

This article focuses on an approach to the concept of historical time in early childhood education through the lens of cognitive psychology. It consists of three parts: (1) theoretical approaches, inspired by three broad scientific fields – cognitive psychology, pedagogy and history; (2) the presentation of educational examples, formed by empirical data and case studies; and (3) conclusions. Its main purpose is to combine theoretical approaches and findings from contemporary scientific research with empirical data from the educational process, so as to argue that kindergarten children can represent and be taught the concept of historical time and, with its help, can be introduced to history education

Iowa Darm Land Values Rise 13 Percent in 1966

Despite a shortage of mortgage money and rising interest rates in the latter half of the year, Iowa farm land values rose at almost record-breaking rates. A breakdown of values for all types of farm land and areas of the state, and the story on why prices rose an average of $38 oer acre are covered by the author
