Gender Differences in Immune Reconstitution: A Multicentric Cohort Analysis in Sub-Saharan Africa

In sub-Saharan Africa, men living with HIV often start ART at more advanced stages of disease and have higher early mortality than women. We investigated gender difference in long-term immune reconstitution

Antiretroviral Therapy Initiation Before, During, or After Pregnancy in HIV-1-Infected Women: Maternal Virologic, Immunologic, and Clinical Response

Pregnancy has been associated with a decreased risk of HIV disease progression in the highly active antiretroviral therapy (HAART) era. The effect of timing of HAART initiation relative to pregnancy on maternal virologic, immunologic and clinical outcomes has not been assessed.We conducted a retrospective cohort study from 1997–2005 among 112 pregnant HIV-infected women who started HAART before (N = 12), during (N = 70) or after pregnancy (N = 30).0.01). There were no statistical differences in rates of HIV disease progression between groups.HAART initiation during pregnancy was associated with better immunologic and virologic responses than initiation after pregnancy

Customer Complaints and Recovery Effectiveness: A Customer Base Approach

Although customer complaints are a well-studied aspect of business, no study has measured the impact of actual complaints and recoveries on subsequent customer purchasing. The authors develop a customer base model to investigate the effectiveness of recovery in preventing customer churn. They calibrate it on panel data that track actual purchases, complaints, and recoveries for 20,000 new customers of an Internet and catalog retailer over 2.5 years. Complaints are associated with a substantial increase in the probability that the customer stops buying, but the size of the increase depends on prior customer experiences: prior purchases mitigate the effect, and their impact is long-lasting, whereas prior complaints exacerbate the effect, but their impact is short-lived. Thus, unless the customer leaves the company after a complaint, or a second failure occurs shortly after the first, the relationship quickly returns to normal. Recovery counters the effect of the complaint but, in almost all cases, does not entirely offset it. The authors use simulation to translate the results to financial impact and discuss implications for researchers and managers

Cloud Computing Adoption Decision Modelling for SMEs: From the PAPRIKA Perspective

The popularity of cloud computing has been growing among enter-prises since its inception. It is an emerging technology which promises competi-tive advantages, significant cost savings, enhanced business processes and ser-vices, and various other benefits. The aim of this paper is to propose a decision modelling using Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA) for the factors that have impact in SMEs cloud computing adoption process
