DEVELOPING PREDICTIVE MODEL FOR POVERTY AND COVID-19 INCIDENCES IN NIGERIA

Poverty is one of the greatest challenges facing the world today. This is because it is a major cause of ill-health by forcing people to live in dirty environments and a barrier to accessing health care, especially in the developing world. As a result of these, it was predicted that the outbreak of the COVID-19 pandemic will pose a devastating impact on households living beneath the economic, social, health and educational services thresholds. This impact will stem from the direct and indirect effects of the illness and the transmission control policies of governments. Consequently, this study assessed the COVID-19 preventive strategies adopted as well as the statistical relationship between the pre and post-lockdown household income poverty in Minna, Nigeria. The study similarly developed a predictive model for the nexus between poverty headcount ratio and the incidence of COVID-19 in Nigeria. Both the primary and secondary sources of data were employed for this study and the data were analysed using descriptive and inferential statistics (t-Test and regression techniques). The outcome showed that there exists a statistically significant difference between the pre-lockdown poverty rate and the post-lockdown poverty rate in Minna. The study also revealed that for each unit increase in poverty headcount ratio, the incidences of COVID-19 cases and its fatalities decreases by -42.5625 and -0.56077 units respectively. The study, therefore, recommended the domestication of the existing social intervention programmes of the Federal Government, by States Governments in order to enhance the standard of living of more households. It was also recommended that all stakeholders most partake in enlightenment and sensitization programmes on the need to adopt preventive measures to guard against the transmission of the virus

Multiple Asteroid Systems: Dimensions and Thermal Properties from Spitzer Space Telescope and Ground-based Observations

We collected mid-IR spectra from 5.2 to 38 microns using the Spitzer Space Telescope Infrared Spectrograph of 28 asteroids representative of all established types of binary groups. Photometric light curves were also obtained for 14 of them during the Spitzer observations to provide the context of the observations and reliable estimates of their absolute magnitudes. The extracted mid-IR spectra were analyzed using a modified standard thermal model (STM) and a thermophysical model (TPM) that takes into account the shape and geometry of the large primary at the time of the Spitzer observation. We derived a reliable estimate of the size, albedo, and beaming factor for each of these asteroids, representing three main taxonomic groups: C, S, and X. For large (volume-equivalent system diameter Deq > 130 km) binary asteroids, the TPM analysis indicates a low thermal inertia (Lambda < or = approx.100 J/1/2 s/K/sq m2) and their emissivity spectra display strong mineral features, implying that they are covered with a thick layer of thermally insulating regolith. The smaller (surface-equivalent system diameter Deff < 17 km) asteroids also show some emission lines of minerals, but they are significantly weaker, consistent with regoliths with coarser grains, than those of the large binary asteroids. The average bulk densities of these multiple asteroids vary from 0.7-1.7 g/cu cm (P-, C-type) to approx. 2 g/cu cm (S-type). The highest density is estimated for the M-type (22) Kalliope (3.2 +/- 0.9 g/cu cm). The spectral energy distributions (SEDs) and emissivity spectra, made available as a supplement document, could help to constrain the surface compositions of these asteroids

A survey of performance enhancement of transmission control protocol (TCP) in wireless ad hoc networks

This Article is provided by the Brunel Open Access Publishing Fund - Copyright @ 2011 Springer OpenTransmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well. Compared to wired networks, wireless ad hoc networks have some specific characteristics such as node mobility and a shared medium. Owing to these specific characteristics of wireless ad hoc networks, TCP faces particular problems with, for example, route failure, channel contention and high bit error rates. These factors are responsible for the performance degradation of TCP in wireless ad hoc networks. The research community has produced a wide range of proposals to improve the performance of TCP in wireless ad hoc networks. This article presents a survey of these proposals (approaches). A classification of TCP improvement proposals for wireless ad hoc networks is presented, which makes it easy to compare the proposals falling under the same category. Tables which summarize the approaches for quick overview are provided. Possible directions for further improvements in this area are suggested in the conclusions. The aim of the article is to enable the reader to quickly acquire an overview of the state of TCP in wireless ad hoc networks.This study is partly funded by Kohat University of Science & Technology (KUST), Pakistan, and the Higher Education Commission, Pakistan

Políticas educacionais no contexto dos “Governos Democrático-Populares” no Brasil: impactos na Educação Infantil

Resumo A centralidade deste artigo é compreender as principais mudanças em termos de políticas públicas educacionais no Brasil entre 2003 e 2012, com foco na primeira fase da Educação Básica, ou seja, a Educação Infantil. No centro desta análise, objetiva-se demonstrar a experiência de criação e implementação do Programa Nacional de Reestruturação e Aquisição de Equipamentos para a Rede Escolar Pública de Educação Infantil - Proinfância, criado na conjuntura dos esforços de lutas e conquistas para que o acesso à educação pública seja garantido para todos e, neste caso, também incluindo a primeira infância. A metodologia utilizada para a construção do artigo baseia-se em procedimentos qualitativos como pesquisa documental e pesquisa bibliográfica. Com efeito, acreditamos que a pesquisa apresenta reflexões que contribuem com o debate sobre as políticas educacionais que priorizam a Educação Básica no Brasil nos anos 2000.Palavras chave: Governos Pós-Neoliberais.

Retrieval of Black Carbon Absorption from Proposed Satellite Measurements Over the Ocean Glint

Haze and air pollution includes many chemicals that together form small particles suspended in the air called aerosols. One of the main ingredients found to affect climate and human health is Black Carbon. Black particles emitted from engines that do not burn the fuel completely, e.g. old trucks. Black carbon absorption of sunlight emerges as one of the key components of man-made forcing of climate. However, global characterization of black carbon emissions, distribution and pathways in which it can affect the amount of solar radiation absorbed by the atmosphere is very uncertain. A new method is proposed to measure sunlight absorption by fine aerosol particles containing black carbon over the ocean glint from a satellite mission designed for this purpose. The satellite will scan the same spot over the ocean in the glint plane and a plane 40 degrees off-glint a minute apart, collecting measurements of the reflected light across the solar spectrum. First the dark ocean off the glint is used to derive aerosol properties. Then the black carbon absorption is derived prop the attenuation of the bright glint by the aerosol layer. Such measurements if realized in a proposed future mission - COBRA are expected to produce global monthly climatology of black carbon absorption with high accuracy (110 to 15%) that can show their effect on climate
