Zonasi Hazard Gempa Bumi Untuk Wilayah Jakarta

Several damaging earthquakes occured in the last decades in Indonesia have alerted the government to mitigate future damages due to earthquake. One of method to minimize the damages is by performing seismic hazard assessment and risk evaluation as the hazard zonation with respect to ground motion characteristics taking into account sources, local geological and soil conditions. This paper performs a microzonation study for Jakarta. Local site effects are assessed by carrying out ground response analysis performed with the NERA routines. The zonation maps are produced with respect to ground shaking intensity in accordance with the manual proposed by World Institute for Disaster Risk Management

‘There will be screen caps’: the role of digital documentation and platform collapse in propagation and visibility of racial discourses

Digital technologies facilitate the existence of online spaces where understandings about race and racial inequality are co-created and contested as part of social networks and within the context of existing power relations and social identities. This project qualitatively explores US college students’ exposure to and experiences with content on social media that they consider to be related to race and racial discrimination. Based on analysis of focus groups, we highlight the role of digital documentation, mediated spillover, and platform collapse as key processes in propagation and communication visibility of racial discourses. We begin by delineating first level-digital documentation that digitally captures local campus and national events from second-level digital documentation – the copying of already digitized content (e.g., via screenshotting). We then introduce the concept of ‘platform collapse’ – second-level digital documentation that enables mediated spillover of content in ways that disrupt discourse architectures, affordances, and audience contexts. Platform collapse emerged in student discussions of how content was documented and moved from relatively private to more public spaces to call attention to racist events, messages, and behavior, and to spur conversations and action. This extended reach and frequency, and also changed the context of racial discourses. Conversely, there was also evidence of platform collapse where content was moved from public to more private spaces to address social groundlessness and avoid masspersonal engagement on social media. We conclude by discussing implications of digital documentation and platform collapse for communication theory and methods

Prevalence and Framing of Health Disparities in Local Print News: Implications for Multilevel Interventions to Address Cancer Inequalities

Background: Americans remain under-informed about cancer and other health disparities and the social determinants of health (SDH). The news media may be contributing to this knowledge deficit, whether by discussing these issues narrowly or ignoring them altogether. Because local media are particularly important in influencing public opinion and support for public policies, this study examines the prevalence and framing of disparities/SDH in local mainstream and ethnic print news. Methods: We conducted a multi-method content analysis of local mainstream (English language) and ethnic (Spanish language) print news in two lower income cities in New England with substantial racial/ethnic minority populations. After establishing intercoder reliability (κ = 0.63–0.88), coders reviewed the primary English and Spanish language newspaper in each city, identifying both disparities and non-disparities health stories published between February 2010 and January 2011. Results: Local print news coverage of cancer and other health disparities was rare. Of 650 health stories published across four newspapers during the one-year study period, only 21 (3.2%) discussed disparities/SDH. Although some stories identified causes of and solutions for disparities, these were often framed in individual (e.g., poor dietary habits) rather than social contextual terms (e.g., lack of food availability/affordability). Cancer and other health stories routinely missed opportunities to discuss disparities/SDH. Conclusion: Local mainstream and ethnic media may be ideal targets for multilevel interventions designed to address cancer and other health inequalities. Impact: By increasing media attention to and framing of health disparities, we may observe important downstream effects on public opinion and support for structural solutions to disparities, particularly at the local level

Is the HERV-K HML-2 Xq2133, an endogenous retrovirus mutated by gene conversion of chromosome X in a subset of African populations, associated with human breast cancer?

The human endogenous retroviruses HERV-K HML-2 have been considered a possible cause of human breast cancer (BrC). A HERV-K HML-2 fully intact provirus Xq21.33 was recently identified in some West African people. We used PCR technology to search for the Xq21.33 provirus in DNA from Nigerian women with BrC and controls. to see if Xq21.33 plays any role in predisposing to BrC. This provirus was detected in 27 of 216 (12.5%) women with BrC and in 22 of 219 (10.0%) controls. These results were not statistically significant. The prevalence of provirus in premenopausal control women 44 years or younger [18/157 (11.46%)} vs women with BrC [12/117 (10.26%)] showed no statistical difference. The prevalence of virus in postmenopausal control women \u3e 45 yrs. was 7.4% (4/54) vs 15.31% (15/98) in postmenopausal women with BrC. These changes were not statistically significant at \u3c.05, but the actual p value of \u3c.0.079, suggests that Xq21.33 might play some role in predisposing to BrC in postmenopausal women. Provirus was present in Ghanaian women (6/87), in 1/6 Pygmy populations and in African American men (4/45) and women (6/68), but not in any Caucasian women (0/109). Two BrC cell lines (HCC 70 and DT22) from African American women had Xq21.33. Env regions of the virus which differed by 2-3 SNPs did not alter the protein sequence of the virus. SNP at 5730 and 8529 were seen in all persons with provirus, while 54% had an additional SNP at 7596.Two Nigerian women and 2 Ghanaian women had additional unusual SNPs. Homozygosity was seen in (5/27) BrC and (2/22) control women. The genetic variation and homozygosity patterns suggested that there was gene conversion of this X chromosome associated virus. The suggestive finding in this preliminary data of possible increased prevalence of Xq21.33 provirus in post-menopausal Nigerian women with BrC should be clarified by a more statistically powered study sample to see if postmenopausal African and/or African American women carriers of Xq21.33 might show increased risk of BrC. The implication of finding such a link would be the development of antiretroviral drugs that might aid in preventing BrC in Xq21.33+ women

Mapping Marginality Hotspots: Geographical Targeting for Poverty Reduction

This mapping approach aims to make the marginalized and poor visible by identifying areas with difficult biophysical and socio-economic conditions. Mapping using different data sources and data types gives deeper insight into possible causal interlinkages and offers the opportunity for comprehensive analysis. The maps highlight areas where different dimensions of marginality overlap - the marginality hotspots - based on proxies for marginality dimensions representing different spheres of life. Furthermore, overlaying the marginality hotspots with the number of poor shows where most of the poor could be reached to help them to escape the spiral of poverty. Marginality hotspots can be found in particular in India and Nepal as well as in several countries in Central and Eastern Africa, such as Eritrea, Mozambique, Central African Republic, the Democratic Republic of Congo, Northern Sudan and large parts of Niger. Maps showing the overlap between marginality and poverty highlight that the largest number of marginalized poor are located in India and Bangladesh, as well as in Ethiopia, Southeastern Africa and some parts of Western Africa
