Improving sentiment analysis of disaster related social media content
No full textSocial media platforms have become the most accessible public communication and broadcast channels. Recently, the world has witnessed the prevailing usage of social media for communication during disasters. Being able to monitor and predict public opinions on social media during disasters allows us to evaluate crisis communication theories in order to design more efficient and effective communication mechanisms during the crisis. However, this potential is yet to be materialized due to difficulties in sentiment analysis of social media content. We propose to augment the effectiveness of such analysis by incorporating social relations in sentiment classification models. This thesis extends previous work substantially by looking at social relations of different nature, focusing on different communication goals at each stage of disaster management. This study provides a quantitative analysis of social media sentiments during disaster utilizing improved sentiment analysis and feature extraction techniques
The Influence of Blended Learning on Post-Secondary Readiness and Academic Achievement in Mathematics: A Personalized Approach to Learning
No full textPersonalized learning through blended learning is emerging as an educational practice with promising potential to close the academic achievement gap in high school mathematics and produce post-secondary ready mathematics learners. National data indicates mathematics growth has stagnated over the past several decades leaving opportunity for innovation to permeate the high school mathematics classroom to influence change. Examining the influence of blended learning on post-secondary readiness and academic achievement in a large urban school district in the southeast region of Texas indicated that blended learning instruction was meeting the promise of personalized learning for all students. The sequential mixed methods study provided observable and teacher perceived characteristics evident in the blended learning classroom while quantitative data measured the influence of blended learning on post-secondary readiness and academic achievement using an independent t-test. Blended learning was further investigated using Chi-squared test of Independence and cross tabulations to investigate the relationship between blended learning and post-secondary readiness as well as academic achievement. Paired samples t-test measured the difference in PSAT scores.
Although no statistical significance was found when measuring post-secondary readiness, pockets of promise emerged when measuring academic achievement. Mean score differences were higher for students participating in blended learning when compared with students participating in traditional learning. Trends in the blended learning classroom demonstrate evidence of self-directed learning orchestrated by the teacher acting as a facilitator. Further evidence of personalization collected during classroom observations and teacher interviews demonstrated that in the blended learning classroom the needs of every student were considered instead of holding all students’ hostage to the pacing of the teacher. The promise of closing the achievement gap in mathematics has great potential as the blended learning model of instruction continues to grow in implementation in the participating district and across the United States
Changes in culture and values among Saudi students' families in the United States, and their impact on the centrality of financial management and purchasing decisions within the family
Get PDFSaudi Arabia and the United States of America have a strong relationship both politically and economically. This is exemplified by the number of Saudi students sent on scholarship to study in the US. Roughly, there are 70 thousands Saudi students enrolled in such scholarships, many of which are accompanied by their wives and kids. Students and their families undergo many changes abroad that are reflected on their overall behaviour. This study aims to investigate changes in culture and values among Saudi students' families in the United States, and their impact on the centrality of financial management and purchasing decisions within the family.
A correlational research design was deployed analyzing a three-part questionnaire of 174 snowball-sampled participants. The first part of the questionnaire gathered socio- demographic information, whereas the second and third parts seek the effect of acculturation to American culture on the participants lives and the changes in the financial management roles within the family.
The regression analysis results showed that H1a studying in the United States has changed the values of Saudi couples (B = 1.369, p<0.001), H1b Assimilation of American culture has changed the traditional gender roles within Saudi families had (B = 1.158, p<0.001), H2a Adoption of American culture by Saudi students has influenced their financial management practices had (B = 0.112, p<0.001), and H2b Financial management is now a joint obligation between Saudi couples in the United States had (B = -0.156, <0.001). The model assumed a 5% level of significance and 95% confidence interval
