    Suppose we have a finite number of distinct points in the plane. We refer to these points as sites. We wish to partition the plane into disjoint regions called cells, each of which contains exactly one site, so that all other points within a cell are closer to that cell\u27s site than to any other site

    Community Disaster Management in the Community of Tio-Angan in the Philippines

    Natural hazards have affected human society throughout history. The Philippines is a country particularly vulnerable to natural hazards due to its geographical location and widespread social vulnerabilities. This research is conducted in the Philippine province La Union, and aims to investigate community-based disaster management as an approach to strengthening disaster resilience of communities. The research design is an explanatory case study, and data was collected through eleven semi-structured interviews and unstructured observations of field work. The study was conducted through an internship in the Philippines, with the organisation Alay Bayan-Luson, Inc. Two research questions are explored. The first investigates the practice of disaster preparedness and response in the community of Tio-Angan, before the members received training in community-based disaster management. This training forms a community disaster management organisation. The second question investigates how and why a community-based approach to disaster management is helping communities increase their disaster resilience. To analyse the collected data, a conceptual framework was constructed, consisting of the concepts disaster risk reduction, disaster risk management, community, vulnerability, capacity, local ownership and resilience. The findings are that members of Tio-Angan community prepare for disasters by telling their neighbours about them and securing their houses and their animals. Post-disaster assessment includes cooperation to clear roads. Furthermore, in communities with an established community organisation for disaster management, members state a greater unity among the people. Moreover, they describe an increased knowledge about disasters and how to mitigate their effects. Implementing community-based disaster management takes time, but the findings show it brings positive effects to the communities targeted

    Promoter analysis of members of a plant defense-related LRR-RLK gene cluster in Arabidopsis thaliana

    M.Sc. (Biochemistry)A 14-member, closely-spaced cluster of genes coding for leucine-rich repeat receptor-like kinases (LRR-RLKs) is located on chromosome 1 of Arabidopsis thaliana. Following on from previous microarray studies that found some of the members of this cluster to be upregulated in response to biotic stressors, including the bacterial elicitor flg22, the present study sought to confirm, using a luciferase-based protoplast assay, that flg22 does in fact induce the expression of the genes, and then to investigate the promoters of the genes. The promoters of At1g51790, At1g51850 and At1g51890 responded positively in this particular assay, and bioinformatic analyses determined that W-boxes are over-represented in the cloned regions. Mutational inactivation of individual W-boxes in the promoter of At1g51790 drastically reduced the flg22 response, except for the W-box closest to the start site, which seemed to increase both basal and flg22-inducible expression. In the promoter of At1g51850, mutational inactivation of either or both of its W-box dyads resulted in virtually no flg22 inducibility. The deletion of 6 W-boxes in the promoter of At1g51890, done via truncation, drastically reduced both its basal expression and its inducible response to flg22. These results provide evidence that W-box cis-elements are responsible for the upregulation of these LRR-RLKs in response to flg22. WRKYs -7, -11, -22,and -26 were found bioinformatically to have similar expression patterns to some of the genes in the cluster, and are thus good candidates to investigate as transcriptional regulators of the cluster in future studies

    Girls in Graphic Novels: A Content Analysis of Selected Texts from YALSA\u27s 2016 Great Graphic Novels for Teens List

    This study examined the portrayal of female characters in selected texts from the Young Adult Library Association\u27s 2016 Great Graphic Novels for Teens list. Appearances, conversations, and behaviors of preteen and teenage female primary characters were coded. Results indicate that progress is being made in the portrayal of female characters in graphic novels. Diversity in appearances, relatable conversations, and a break from stereotypical behaviors have led to more complex characters that provide readers with better role models. While some stereotypical conventions remain, the progress indicates a positive change for all readers
