Voices of home and school on democracy and human rights education at the primary level: a case study
The purpose of this research was to investigate the perceptions of home and school concerning ideally implemented primary
democracy and human rights education. In this qualitative study, data were collected from six voluntary classroom teachers
and 16 parents in a selected school through interviews. The results of the interview yielded five major themes: physical and
environmental issues, instructional process, teacher characteristics, assessment practices, and communication patterns for
teaching democracy and human rights ideally. Most of the participants also indicated the lack of partnership between home
and school. The results showed that there are gaps between the existing and desired conditions of democracy and human rights
education in schools. 相似文献

Spontaneous alternating behavior (SAB), the tendency of an organism to successively turn left and right in a maze, is a standard
metric of short-term memory in developmental and pyschopharmacological studies. Although SAB is perhaps the most phylogenetically
widespread behavior in motile lifeforms, conflicting data on SAB exist for several sets of closely related taxa. For example,
previous studies provide contradictory evidence concerning the existence of spontaneous alternation behavior in the protozoanParamecium. However, these studies tested different species, using very different experimental designs. Using a single, factorial design
for both previously tested species,P. multimicronucleatum andP. caudatum, we found that, in fact, the two species do not differ in their alternation behavior; specifically, they alternate in mazes
with short tracks, but not in mazes with long tracks. These results are in accord with alternation studies on other taxa,
and they fully resolve the apparent contradictions in the earlier studies onParamecium. They also indicate that caution should be used in interpreting variable results across species tested with different experimental
designs and suggest that, in at least some taxa, SAB may not be strictly dependent on the use of short-term memory. 相似文献

We introduce fast filtering methods for content-based music retrieval problems, where the music is modeled as sets of points
in the Euclidean plane, formed by the (on-set time, pitch) pairs. The filters exploit a precomputed index for the database,
and run in time dependent on the query length and intermediate output sizes of the filters, being almost independent of the
database size. With a quadratic size index, the filters are provably lossless for general point sets of this kind. In the
context of music, the search space can be narrowed down, which enables the use of a linear sized index for effective and efficient
lossless filtering. For the checking phase, which dominates the overall running time, we exploit previously designed algorithms
suitable for local checking. In our experiments on a music database, our best filter-based methods performed several orders
of a magnitude faster than the previously designed solutions. 相似文献

In the project ‘Competence-Driven Project Portfolio Analysis’ (CDPPA), an integrated system for supporting R&D project selection, staff assignment and activity scheduling with special consideration of the strategic development of competencies has been designed and implemented prototypically. The system has been field-tested at the Electronic Commerce Competence Center (EC3), a public–private partnership R&D enterprise. Experiences from this trial application are summarised and discussed, particularly concerning data collection and competence measurement, the benefits and limits of the chosen multi-criteria decision analysis approach, the evaluation of introduced changes to the decision-making processes, and the transparency of the formal planning model and its components. 相似文献

Along with the advent of Web 2.0, mass collaboration is of paramount importance in knowledge exploration and diffusion. However, the extent to which Internet-based collaboration technologies can be used to develop new knowledge and to leverage the wisdom of crowds heavily depends on the collective willingness to adopt such tools together. In this study, the adoption and use of instant messaging has been conceptualized as a group-referent intentional social action. The concept of ‘we-intention’, which refers to one's perception of the group acting as a unit, is the focus of our interest. The cognitive, affective and social dimensions that contribute to ‘we-intention’ to adopt and use instant messaging were investigated. A survey was conducted and the findings provided empirical evidence supporting the idea that cognitive, affective and social factors jointly lead to the development of we-intention. This study is expected to provide some useful insights to both researchers and practitioners. 相似文献

The paper reports a case study where a relatively lightweight technology in the form of a Web-based questionnaire was used to support members of a real community of professionals in externalizing and sharing their good practices and achieving a better awareness of and agreement on topics of common interest. We focused on an important medical association that counts more 1000 doctors all around the world as its members. In particular, we report how this association used the occasion of the on-line survey enabled by our technology to increase the awareness of its members about the actual heterogeneity of preferences existing in their daily clinical practice, and to trigger discussion toward a better consensus on best practices, appropriate indications, and treatments of choice for their profession and practice. We also report the result of a post-hoc evaluation of the Web-based technology employed, and draw some implications for the better design of this kind of tool in order to collect and share collective knowledge in specific professional domains. 相似文献

High concentration of thyroglobulin antibodies (TgAb) is a major limiting factor of thyroglobulin measurements in patients with differentiated thyroid cancer. We investigated whether thyroglobulin antibody added to serum samples could interfere with the thyroglobulin assay. Thyroglobulin levels in serum samples with different concentrations of thyroglobulin were measured by electrochemiluminescence immunoassay before and after the addition of increasing concentrations of thyroglobulin antibody using the secondary calibrator solution of the thyroglobulin assay kit containing sheep thyroglobulin antibody to reach thyroglobulin antibody levels within or near to the reference range. Thyroglobulin and thyroglobulin antibody concentrations were also measured in 134 serum samples from 27 patients after thyroid ablation. There was a strong negative association (slope = −1.179) between thyroglobulin antibody and thyroglobulin concentrations in samples with added thyroglobulin antibody (beta = −0.86; P < 0.001). Changes in thyroglobulin concentrations were described mathematically as loss of thyroglobulin% = −0.2408 × Ln(thyroglobulin antibody IU/ml) + 0.1944. Thyroglobulin concentrations were significantly lower than those calculated from experiments with added thyroglobulin antibody in 26/134 samples from patients after thyroid ablation. We conclude that if the same TgAb interference exists in the presence of naturally occurring human TgAb, our observation may prove to be useful during follow-up of patients with differentiated thyroid cancer. However, further studies are needed to explore the clinical relevance of thyroglobulin antibody levels within or near to the reference range in monitoring these patients. 相似文献
