This paper examines current trends in family studies research, details the methodological and topical perspectives that are emerging, and reflects on how these findings could be integrated to provide a more coherent approach to researching the leisure, learning and recreational aspects of family visitors to art museums. Research findings from disciplines such as sociology, ethnography, education, design and marketing are of interest to the field of visitor studies, and this paper contributes to the wider research agenda by providing an overview of family research methods from a range of other disciplines, as well as those used within visitor studies.Over the last decade, there has been a growth of research in family learning in science museums, leading to an emerging disciplinary matrix, whilst many aspects of family visits to art museums remain relatively unexplored. The paper discusses the problems of gathering meaningful data from adults and children in family groups, and concludes by suggesting that a challenge for art museums is to learn from what is happening in other areas of cultural research into families, and to develop a framework for research which builds on the methodological strengths and practical experience of robust studies.  相似文献

The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and control group students took the Achievement Test in Reproduction, Development, and Growth in Living Things (RDGLT), Science Process Skills Test, and Attitudes Toward Science Questionnaire, as pre-test and post-test. Repeated analysis of variance design was used in analyzing the data. Both the experimental and control group students were taught in RDGLT units for 22 class hours. The results indicated the positive effect of guided-inquiry approach on the Turkish students' cognitive as well as affective characteristics. The guided inquiry enhanced the experimental group students' understandings of the science concepts as well as the inquiry skills more than the control group students. Similarly, the experimental group students improved their attitudes toward science more than the control group students as a result of treatment. The guided inquiry seems a transition between traditional teaching method and student-centred activities in the Turkish schools.  相似文献

This study, guided by the Family Systems Theory, examines the direct effect of maternal use of corporal punishment on children's adjustment difficulties. Also, it explores whether corporal punishment serves as a mediating factor in the relationship between several maternal characteristics, marital relationships, and children's adjustment difficulties. A total of 2,447 Arab mothers completed anonymous, structured, self-report questionnaires. The use of corporal punishment was generally strongly supported by the Arab mothers in our sample. A greater likelihood of using corporal punishment was found among mothers of boys rather than girls, among mothers with lower perceived self-efficacy to discipline children, and among mothers with a lower perception of their husbands’ participation in child-related labor. In addition, the higher a mother's reports on disagreement with her husband about discipline methods and the stronger her level of maternal stress, the more likely she was to use corporal punishment. Corporal punishment also mediated the association between the above mentioned factors and child adjustment difficulties. Furthermore, a husband's emotional support and family socioeconomic status were directly associated to children's adjustment difficulties. The results of the current study emphasize the need to observe children's development within the context of their family systems and to consider the mutual influences of different subsystems such as marital relationships and mother–child interactions. Prevention and intervention programs should raise parents’ awareness concerning the harmful effects of corporal punishment and take into account the impact of dynamic transactions of parental conflicts and disagreements regarding discipline methods on child outcomes.  相似文献

This paper presents an approach to planning academic courses for pre-service teachers and for researching development of teacher identity. The approach was implemented in a course, conducted in an Israeli Master Teach program, designed to foster pre-service teacher identity transformation. The research described here addresses two questions: (1) To what extent does the approach contribute to the understanding of teacher identity formation? (2) Using this approach, how can pre-service teacher educators support teacher identity transformation? Using a metaphorical tool, students designed their ‘ideal school’ at the beginning and at the end of the course. Identity transformation was evaluated by comparing their designs. Demonstration of this approach methodology is presented through an analysis of the designs of one female student. Findings highlight the potential of this approach to reveal and cope with obstacles inhibiting transformative learning: narrow, imbalanced, inconsistent, and shallow perspective; rigid patterns of thinking; and lack of emotional awareness.  相似文献

Introduction

Preanalytical specifications for urinalysis must be strictly adhered to avoid false interpretations. Aim of the present study is to examine whether the preanalytical factor ‘time point of analysis’ significantly influences stability of urine samples for urine particle and dipstick analysis.

Materials and methods

In 321 pathological spontaneous urine samples, urine dipstick (Urisys™2400, Combur-10-Test™strips, Roche Diagnostics, Mannheim, Germany) and particle analysis (UF-1000 i™, Sysmex, Norderstedt, Germany) were performed within 90 min, 120 min and 240 min after urine collection.

Results

For urine particle analysis, a significant increase in conductivity (120 vs. 90 min: P < 0.001, 240 vs. 90 min: P < 0.001) and a significant decrease in WBC (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), RBC (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), casts (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001) and epithelial cells (120 vs. 90 min P = 0.610, 240 vs. 90 min P = 0.041) were found. There were no significant changes for bacteria. Regarding urine dipstick analysis, misclassification rates between measurements were significant for pH (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), leukocytes (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), nitrite (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), protein (120 vs. 90 min P < 0.001, 240 vs. 90 min P<0.001), ketone (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), blood (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001), specific gravity (120 vs. 90 min P < 0.001, 240 vs. 90 min P < 0.001) and urobilinogen (120 vs. 90 min, P = 0.031). Misclassification rates were not significant for glucose and bilirubin.

Conclusion

Most parameters critically depend on the time window between sampling and analysis. Our study stresses the importance of adherence to early time points in urinalysis (within 90 min).Key words: urinalysis, automation, analytical sample preparation methods, flow cytometry, specimen handling  相似文献

Determination of HbA1c values with high performance liquid chromatography (HPLC) occasionally reveals hemoglobin anomalies with no or minimal clinical evidence. We coincidentally detected two cases of Hb Hasharon, an alpha globin gene mutation, in two heterozygous patients and one case of Hb NYU, a delta globin gene mutation, in another patient. Both anomalies have not been described in subjects of German origin to date. Characterization was carried out with HPLC, hemoglobin electrophoresis, capillary zone electrophoresis, DNA sequencing, complete blood count and clinical chemical analysis.  相似文献
