地理乡村课程资源是广泛存在于乡村社会中有利于实现地理课程教学目标的所有教育资源的总和.由于认识等方面的原因,乡村社会丰富的课程资源没有被充分重视并运用于高中地理教学过程中,导致大量有价值的课程资源的闲置与浪费.高中地理教学过程中开展乡村课程资源开发利用途径探索,把宝贵的乡村课程资源应用于地理教学,对于提高教学质量具有重要的作用. 相似文献

Introduction:
There are a number of pre-analytical and analytical factors, which cause false results in the complete blood count. The present case identifies cold agglutinins as the cause for the mismatch between hematocrit and hemoglobin values.Materials and methods:
70-year old female patient had a history of cerebrovascular diseases and rheumatoid arthritis. During routine laboratory examination, the patient had normal leukocyte and platelet counts; however, the hemoglobin (Hb: 105 g/L) and hematocrit (HCT: 0.214 L/L) results were discordant. Hemolysis, lipemia and cold agglutinin were evaluated as possible reasons for the mismatch between hematocrit and hemoglobin values.Results:
First blood sample was slightly hemolysed. Redrawn sample without hemolysis or lipemia was analyzed but the mismatch became even more distinct (Hb: 104 g/L and HCT: 0.08 L/L). In this sample, the titration of the cold agglutinin was determined and found to be positive at 1:64 dilution ratios. After an incubation of the sample at 37°C for 2 hours, reversibility of agglutination was observed.Conclusion:
We conclude that cold agglutinins may interfere with the analysis of erythrocyte and erythrocyte-related parameters (HCT, MCV, MCH and MCHC); however, Hb, leukocyte and platelet counts are not affected. 相似文献4.

This mixed-methods research compared job satisfaction among counselors working in pre-schools and primary-schools. Its quantitative phase included 223 counselors, 70 of whom also participated in the qualitative phase. A demographic information form, job-satisfaction scale and a semi-structured interview protocol were used to collect data. Quantitative analysis indicated that the primary-school counselors’ job satisfaction was higher than that of the pre-school counselors. There were no statistically significant differences in satisfaction between the two groups based on gender, age, or marital status, or the interaction of any of those three demographic factors with the type of school where they worked. In the qualitative phase, approximately half of the primary-school counselors but just one-third of the pre-school counselors reported their job satisfaction as being high; and around half of the pre-school group and one-third of the primary-school group reported that school type where they worked had a negative impact on their job satisfaction. 相似文献

This study elaborates the roles of mediators especially as enablers in knowledge creation. These roles are studied in the context of the TARU EU EQUAL training programme, aimed at helping marginal artists to enter the professional community of artists. The results indicate that the mediator roles identified from literature can be adapted to learning. However, they do not include the role of a mediator as enabling identity building, which is important in the learning context. Moreover, the mediating tasks occurring within communities merit more attention. In addition, the analysis revealed that the mediators' understandings of learning differed from those of the participants, which affected the activities and mediator roles. The use of ba and communities of practice as tools of knowing when analysing the mediator roles proved beneficial as they revealed different aspects and brought forth various ways to enable learning. 相似文献
