LSSGalPy: Interactive Visualization of the Large-scale Environment Around Galaxies
New tools are needed to handle the growth of data in astrophysics delivered
by recent and upcoming surveys. We aim to build open-source, light, flexible,
and interactive software designed to visualize extensive three-dimensional (3D)
tabular data. Entirely written in the Python language, we have developed
interactive tools to browse and visualize the positions of galaxies in the
universe and their positions with respect to its large-scale structures (LSS).
Motivated by a previous study, we created two codes using Mollweide projection
and wedge diagram visualizations, where survey galaxies can be overplotted on
the LSS of the universe. These are interactive representations where the
visualizations can be controlled by widgets. We have released these open-source
codes that have been designed to be easily re-used and customized by the
scientific community to fulfill their needs. The codes are adaptable to other
kinds of 3D tabular data and are robust enough to handle several millions of
objects.Comment: 7 pages, 2 figures; accepted for publication in PASP Special Focus

A Tale of Two Markets: How Lower-end Borrowers Are Punished for Bank Regulatory Failures in Nigeria
In 2009, the Nigerian banking system witnessed a financial crisis caused by elite borrowers in the financial market. Regulatory response to the Nigerian crisis closely mirrored the international response with increased capital and liquidity thresholds for commercial banks. While the rise of consumer protection on the agenda of prudential supervisors internationally was logical in that consumer debt was the main cause of the global recession, the Nigerian banking reforms of 2009 disproportionately affected access by poorer consumers, who ironically had little to do with the underlying causes of the crisis. As lending criteria become more stringent, poorer consumers of credit products are pushed into informal markets because of liquidity-induced credit rationing. Overall, consumer protection is compromised because stronger consumer protection rules for the formal sector benefits borrowers from formal institutions who constitute the minority of borrowers in all markets. While the passage of regulation establishing credit bureaux and the National Collateral Registry will, in theory, ease access to credit especially by lower-end borrowers, the vast size of the informal market continues to compound the information asymmetry problem, fiscal policies to tackle structural economic issues such as unemployment and illiteracy remain to be initiated, and bank regulators continue to pander to elite customers with policy responses that endorse too big to fail but deems lower-end consumers too irrelevant to save. The essay concluded that addressing the wide disparity in access to credit between the rich and poor through property rights reforms to capture the capital of the informal class, promoting regulation to check loan concentration, and stimulating competition by allowing Telecommunication Companies (TELCOs) and fintech companies to carry on lending activities because of their superior knowledge of lower-end markets will facilitate greater access. The risk of systemic failure deriving from consumer credit in Nigeria is insignificant compared to the consumer vulnerabilities resulting from the exposure of consumers to unregulated products in the informal market
The "Statinth" wonder of the world: a panacea for all illnesses or a bubble about to burst
After the introduction of statins in the market as effective lipid lowering agents, they were shown to have effects other than lipid lowering. These actions were collectively referred to as 'pleiotropic actions of statins.' Pleiotropism of statins formed the basis for evaluating statins for several indications other than lipid lowering. Evidence both in favour and against is available for several of these indications. The current review attempts to critically summarise the available data for each of these indications

Popular Participation and Social Assistance: a Contradictory Dimension of a Special Law
This article responds to the interest in analyzing theoretical concepts referring to social policies, and discusses a new cartography of categories related to the debate about popular participation in social assistance policy. Breaking with a trend that seeks to disable an active role by the masses, this study is part of a commitment to expanding thinking about social policy beyond the traditional realm – in which the policy is simply a strategy to accommodate conflicts – and to emphasize its political and liberating potential. It also seeks to contribute to the analysis of current social policies, concerning possibilities or interdictions, as strategies to fight inequality and guarantee rights, based on the political dispute for the surplus expropriated from the masses
