高中地理教学中乡村课程资源开发利用途径初探

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.     

The Effectiveness of a Brief Mindfulness-Based Intervention for College Freshmen Who Have Aged out of Foster Care

This study investigated the effects of a brief meditation intervention on perceived stress, mindfulness, and sleep quality for college freshmen who have aged out of foster care. Thirty-six youth who had aged out of foster care and enrolled at a large midwestern 4-year university (n?=?16 experimental group, n?=?20 control group) participated in a study in which they were assessed three times on the dependent variables. Students also participated in a focus group after the intervention ended. Four sessions of the brief mindfulness intervention resulted in significant short-term reductions in stress levels and increases in sleep quality. Finding effective personal interventions to increase chances for college success for students with histories in foster care can also offer potential insight toward the development of educational models and resources for other vulnerable college student populations.

Child Maltreatment and Children's Developmental Trajectories in Early to Middle Childhood

Associations between experiencing child maltreatment and adverse developmental outcomes are widely studied, yet conclusions regarding the extent to which effects are bidirectional, and whether they are likely causal, remain elusive. This study uses the Fragile Families and Child Wellbeing Study, a birth cohort of 4,898 children followed from birth through age 9. Hierarchical linear modeling and structural equation modeling are employed to estimate associations of maltreatment with cognitive and social‐emotional well‐being. Results suggest that effects of early childhood maltreatment emerge immediately, though developmental outcomes are also affected by newly occurring maltreatment over time. Additionally, findings indicate that children's early developmental scores predict their subsequent probability of experiencing maltreatment, though to a lesser extent than early maltreatment predicts subsequent developmental outcomes.     

70-year old female patient with mismatch between hematocrit and hemoglobin values: the effects of cold agglutinin on complete blood count

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.     

School Counselors’ Job Satisfaction: a Comparative Study of Preschool and Primary-School Counselors in Turkey

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.

Analysis of the Meanings of the Antiderivative Used by Students of the First Engineering Courses

In this article, we present the results of the administration of a questionnaire designed to evaluate the understanding that civil engineering students have of the antiderivative. The questionnaire was simultaneously administered to samples of Mexican and Colombian students. For the analysis of the answers, we used some theoretical and methodological notions provided by the theoretical model known as Onto-Semiotic Approach (OSA) to mathematical cognition and instruction. The results revealed the meanings of the antiderivative that are more predominantly used by civil engineering students. Also, the comparison between the mathematical activity of Mexican and Colombian students provides information that allows concluding that the meanings mobilized could be shared among their communities and are not particular of their classroom or university.
