Adult development and adult learning styles: The message for nontraditional graduate programs 总被引:1,自引:0,他引:1
Both the content and process of graduate education promote adult development. As developing people, adults usually enroll in graduate programs at times when they are building or changing the structure of their lives. Graduate programs, particularly nontraditional programs, can address both the growing adult as well as uphold relevant standards of intellectual excellence and professional expertise.Their collaborative research has focused on life cycle adult development and on educational methodologies and environments which support adult development. 相似文献

Introduction
Glycolysis affects glucose determination in vitro. The placement of sample tubes in ice-water slurry with plasma separation within 30 minutes is recommended, or alternatively the use of a glycolysis inhibitor. The aim of our two-steps study was to evaluate which Terumo tube is best for glucose determination in routine clinical setting.Materials and methods
In the first study, blood from 100 volunteers was collected into lithium heparin (LH), NaF/Na heparin (FH) and NaF/citrate buffer/Na2EDTA (FC-Mixture) tubes. LH sample was treated as recommended and considered as reference, while FH and FC-Mixture samples were aliquoted, maintained at room temperature (RT) for 1, 2 and 4 hours; centrifuged and plasma analysed in triplicate. In the second study, samples from 375 volunteers were collected in LH, FH and FC-Mixture tubes and held at RT before centrifugation from 10 to 340 minutes, depending on each laboratory practice. Samples were analysed in one analytical run.Results
In the first study, FH glucose concentrations were 5.15 ± 0.66 mmol/L, 5.05 ± 0.65 mmol/L and 5.00 ± 0.65 mmol/L (P < 0.001) in tubes stored at RT for 1, 2 and 4 hours, respectively. Mean biases in all time points exceeded the analytical goal for desirable bias based on biological variation criteria. FC-Mixture glucose concentrations were 5.48 ± 0.65 mmol/L, 5.46 ± 0.6 mmol/L and 5.46 ± 0.64 mmol/L in tubes stored at RT for 1, 2 and 4 hours, respectively. Mean biases for FC-Mixture glucose in all time points reached optimal analytical goals. In the second study, the biases for LH and FH glucose compared to reference FC-Mixture glucose exceeded the preset analytical goals, regardless of the blood collection to centrifugation time interval.Conclusions
FC-mixture tubes glucose concentrations were preserved up to 4h storage at RT. We confirmed that NaF alone does not allow immediate glycolysis inhibition in real life pre-centrifugation storage conditions (up to 340 minutes). FC-Mixture should be used exclusively for glucose determination in laboratories unable to implement the recommended blood samples’ treatment.Key words: glucose, pre-analytical phase, sodium fluoride, citrate acidification, stability 相似文献83.

The given paper presents the results of an empirical study into the efficacy of the Thinking Approach (TA) to language teaching and learning which is aimed at the development of students’ inventive thinking skills in the context of foreign language education, namely learning of English. The study was conducted among upper secondary students of two schools in Latvia and aimed to answer whether students working with the Thinking Approach demonstrate an increase in their inventive thinking skills. An inventive thinking test was employed as the research instrument. The results of the study suggest that students working with the TA demonstrate a significant increase in their inventive thinking skills in comparison with the control group (t = 3.32, p = 0.001). At the same time a number of limiting factors that appeared in the process of the study due to its naturalistic setting call for further research that could increase the reliability of the findings. 相似文献

Myocardial infarction is a major consequence of coronary artery disease. Apart from the traditional risk factors of myocardial
infarction, recently many reports have suggested that hyperhomocysteinemia plays important role in myocardial infarction.
Plasma homocysteine level was determined in 60 myocardial infarction patients and in 35 age matched healthy individuals. Statistically
significant differences (p<0.01) were observed in the mean of plasma homocysteine concentrations between the acute myocardial
infarction patients (24.59±6.14 mM/L) and in normal healthy individuals (13.73 ±3.54 mM/L). The level of homocysteine in myocardial
infarction patients is significantly high (p <0.01) among myocardial infarction patients when compared to that of the controls.
The the present study indicates a strong association between plasma homocysteine and acute myocardial infarction among Tamilians,
thus implying plasma homocysteine as a possible risk factor for myocardial infarction. 相似文献

Rita Jordan 《British Journal of Special Education》2008,35(1):11-15
Rita Jordan, Professor in Autism Studies at the School of Education, University of Birmingham, gave last year's Gulliford Lecture at the University of Birmingham on 4 October 2007. This article is based upon that lecture. In it, Professor Jordan discusses the role of education in the lives of people with autistic spectrum disorders. She traces the growth in our knowledge about autistic spectrum disorders and the development of a variety of ways of responding to autism, from the highly specialised, and frequently strictly segregated, to the explicitly inclusive. She uses her analysis to draw distinctions between 'therapeutic' models of education and education as 'entitlement'– and identifies problems with either paradigm. Professor Jordan closes her article by setting out her vision for a future in which there is greater flexibility and diversity and in which specialisation has a key role to play in making inclusion a working reality. The challenge of teaching pupils with autistic spectrum disorders will, argues Professor Jordan, help us all to imagine a truly inclusive model for education in which equity is achieved by treating all learners differently. 相似文献

The role of context in learning and instructional design 总被引:4,自引:0,他引:4
Martin Tessmer Rita C. Richey 《Educational technology research and development : ETR & D》1997,45(2):85-115
Context is a pervasive and potent force in any learning event. Yet instructional design models contain little guidance about how to accommodate contextual elements to improve learning and transfer. This paper defines context, outlines its levels and types, specifies some pertinent contextual factors within these types, suggests methods for conducting a contextual analysis and utilizing its results for instructional design, and outlines future issues for context-based instructional design. The incorporation of a contextual approach to instruction will make our design models systemic as well as systematic. 相似文献

Although the concept of mentoring is receiving increasing attention in the counseling field, the intersection between multiculturalism
and mentoring has not been formally addressed. This article explores mentoring relationships between faculty and students
within counselor education from a multicultural perspective. Semi-structured interviews were used to explore African American,
Asian American and Latina/o American counselor education graduate students’ perspectives on mentoring. Three similar themes
(trust/comfort/honesty; respect; and teacher/student/guide) emerged for all three racial/ethnic groups as important key elements
in the mentoring relationship, but with some distinctive culturally relevant variations in emphasis. Also, all three groups
to some degree reported that having a mentor who was culturally competent and sensitive was helpful, adding further weight
to the view that cultural issues play a role in mentoring relationships. Implications of the findings are discussed. 相似文献
