Factors affecting differential equation problem solving ability of Pre-University level students in a selected province in Pakistan / Aisha Bibi
The role of differential equations (DEs) is very important in the modern technological era to inter-relate and solve a variety of routine daily life problems. Several approaches (algebraic, numerical and graphical) have been developed and more are being developed to make DEs course more effective and valuable. Several studies also have well elaborated the students’ epistemological math problem solving beliefs, goal orientations and self-regulated learning (SRL) towards DEs problem solving. However, in spite of the great importance of these factors, no study had related these four factors. Therefore, this quantitative correlational study was designed to relate and model these three factors particularly for DEs problem solving. The purpose of this study was to explore the factors affecting DEs problem solving, particularly epistemological math problem solving beliefs, usefulness, goal orientations and self-regulated learning strategies at pre-university level students in a selected province in Pakistan. Specifically, the objectives of this study were i) to investigate the direct effect of epistemological math problem solving beliefs, usefulness, goal orientations and self-regulatory learning (SRL) strategies towards differential equation problem solving and; ii) to examine the mediating role of goal orientations and self-regulatory learning (SRL) strategies. Three different types of the adapted questionnaires along with an assessment test containing five self-developed non-routine differential equation tasks were distributed to 430 pre-university students, studying in public and private institutions. Collected data were analyzed using SPSS and SmartPLS software. Both direct and indirect effects of the selected factors on DE problem solving were measured. The analysis of the direct paths revealed that epistemological math problem solving beliefs, self-regulated learning strategies, and goal orientations strongly affected the DE problem solving. In the second phase of the study, mediation roles were identified. For this, initially the mediation effects of goal orientations (mastery, performance and avoidance goals) were considered. The findings revealed that epistemological math problem solving beliefs strongly affected the DE problem solving via mastery, performance, but the effect of avoidance goal was non-significant and negative. While considering the mediation effect of self-regulated learning strategies (critical thinking and elaboration), results revealed that epistemological math problem solving beliefs strongly affected the DE problem solving via elaboration, however, through critical thinking no significant effects were observed. Finally, findings have shown that elaboration had played the role of mediation for master and performance goals, while no such effect was observed for avoidance. Overall it can be concluded that epistemological math problem solving beliefs, usefulness, goal orientations (both mastery and performance goals) and elaboration can be effectively employed to boost the students’ ability to solve DE problems and to ensure that teaching and learning of differential equation may become more effective and meaningful
The cultures and properties of decaying buildings
This article focuses on controversial plans by the government to rebuild Aisha Bibi, a small, crumbling mausoleum in southeastern Kazakhstan, and thereby hitch its symbolic potency to the nationalist drive. There has never been one commonly accepted account of the building in terms of when and by whom it was created. Nonetheless, it has long been a site of pilgrimage for many different groups and, since the Soviet period, a source of scientific interest. Plans to construct a replica building have brought the multitude of previously co-existing narratives into sharp relief as the new version threatens to oust the others, effectively making one narrative claim exclude others. Further, as is the nature of all representations, the replica will halt and contain the unboundedness and perishability of the mausoleum which, for many local narratives, is an essential part of Aisha Bibi
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
