Do Remittances Help Smooth Consumption During Health Shocks? Evidence From Jamaica

We identify whether remittances facilitate consumption smoothing during health shocks in Jamaica. In addition, we investigate whether remittances are subject to moral hazard by receivers, how the informal insurance provided by remittances interacts with formal health insurance, and whether there are differential effects by gender of the household head. We find that remittances offer complete insurance toward decreased consumption during health shocks and that moral hazard is weak. The role of remittances as a social insurance mechanism, however, is relevant only in the absence of private health insurance. No differential effects by gender of the household head are found

Design of a control architecture for an underwater remotely operated vehicle (ROV) used for search and rescue operations

summary:A control system architecture design for an underwater ROV, primarily Class I - Pure Observation underwater ROV is presented in this paper. A non-linear plant model was designed using SolidWorks 3D modeling tool and is imported to MATLAB as a 3D model. The non-linear modeled plant is linearized using the MATLAB linear analysis toolbox to have a linear approximate model of the system. The authors designed controllers for the linear plant model of underwater ROV. PID controllers are utilized as a controller of the modeled plant. The PID tuning tools by MATLAB are utilized to tune the controller of the plant model of underwater ROV. The researchers test the control design of underwater ROV using MATLAB Simulink by analyzing the response of the system and troubleshoot the control design to achieve the objective parameters for the control design of underwater ROV

Bacterial resistance to antibiotic alternatives: a wolf in sheep’s clothing?

peer-reviewedImplications • Substantial pressure to reduce antibiotic use has necessitated the development of antibiotic alternatives. However, relatively little consideration has been given to the development of resistance to these alternatives. • Whether we come up with antibiotic alternatives that are bacteriocidal or inhibitory, bacteria will continue to adapt and evolve. • Some antibiotic alternatives support the development of antibiotic resistance necessitating caution. • There are opportunities to optimize antibiotic alternative effectiveness as well as to minimize the development of resistance mechanisms

Evidence that breast cancer risk at the 2q35 locus is mediated through IGFBP5 regulation.

GWAS have identified a breast cancer susceptibility locus on 2q35. Here we report the fine mapping of this locus using data from 101,943 subjects from 50 case-control studies. We genotype 276 SNPs using the 'iCOGS' genotyping array and impute genotypes for a further 1,284 using 1000 Genomes Project data. All but two, strongly correlated SNPs (rs4442975 G/T and rs6721996 G/A) are excluded as candidate causal variants at odds against >100:1. The best functional candidate, rs4442975, is associated with oestrogen receptor positive (ER+) disease with an odds ratio (OR) in Europeans of 0.85 (95% confidence interval=0.84-0.87; P=1.7 × 10(-43)) per t-allele. This SNP flanks a transcriptional enhancer that physically interacts with the promoter of IGFBP5 (encoding insulin-like growth factor-binding protein 5) and displays allele-specific gene expression, FOXA1 binding and chromatin looping. Evidence suggests that the g-allele confers increased breast cancer susceptibility through relative downregulation of IGFBP5, a gene with known roles in breast cell biology
