Exploiting Inferential Structure in Neural Processes

Neural Processes (NPs) are appealing due to their ability to perform fast adaptation based on a context set. This set is encoded by a latent variable, which is often assumed to follow a simple distribution. However, in real-word settings, the context set may be drawn from richer distributions having multiple modes, heavy tails, etc. In this work, we provide a framework that allows NPs’ latent variable to be given a rich prior defined by a graphical model. These distributional assumptions directly translate into an appropriate aggregation strategy for the context set. Moreover, we describe a message-passing procedure that still allows for end-to-end optimization with stochastic gradients. We demonstrate the generality of our framework by using mixture and Student-t assumptions that yield improvements in function modelling and test-time robustness

Validation study of LQAS-2 in Uttar Pradesh behavior change management project

India’s Uttar Pradesh Behavior Change Management project studied the potential of community mobilization through Self Help Groups (SHGs) to improve healthy behaviors that may have a direct bearing on maternal, newborn, and child health outcomes. Multiple rounds of Lot Quality Assurance Sampling (LQAS) surveys were undertaken to monitor project activities and take corrective measures to improve project indicators. The surveys also evaluated the diffusion of health messages in the project area. The LQAS-2 validation study aimed to examine the accuracy of LQAS-2 data and understand the process of administering the LQAS. The study, which documented the process of survey administration, accuracy of data, and effects of mentor support, used two approaches: a validation survey among a subsample of women who participated in LQAS-2, and observation of the sampled interviews during the LQAS-2 survey. The following programmatic recommendations were made: A longer training of the interviewers is necessary. Prolonged mentor support should be replaced by limited mentoring, but better mentor training is necessary so individuals can properly interview even without mentoring support

Creating the conditions for scale-up of the Men in Maternity intervention in India

The Frontiers in Reproductive Health (FRONTIERS) program conducted an operations research study, called the Men in Maternity (MiM) study, in collaboration with the Employees\u27 State Insurance Corporation of India (ESIC), aimed at involving men in the antenatal and postpartum care of their partners to raise knowledge and use of postpartum contraception and preventive practices against sexually transmitted infections, as well as improving pregnancy outcomes. This report details the MiM scale-up process, which worked well in terms of ESIC assuming ownership of the training component of the program and being able to build capacity for training. However, to further scale up MiM in the remaining dispensaries in Delhi there needs to be commitment from ESIC for supervision and monitoring of the implementation process so that delays can be minimized and MiM can be fully integrated into the dispensary norms for maternity services. To fully institutionalize MiM in ESIC services, limited and continued external support is required, particularly in the area of supportive supervision and MIS. This could perhaps be achieved through expansion, better coordination with implementing hospitals, and reinforcement of similar messages in different venues such as ESIC hospitals

Training manual on basic monitoring and evaluation of social and behavior change communication health programs

Social and behavior change communication (SBCC) interventions are key for addressing social and cultural barriers and achieving goals laid out for health programs. Often these interventions are not evidence based and monitoring and evaluation (M&E) is limited. Lack of trained and skilled human resources for M&E has been a limitation in general. A serious effort is needed to build the capacity of M&E personnel to monitor and evaluate performance of SBCC interventions in terms of reach and effectiveness among intended audiences. The Improving Healthy Behaviors Program of FHI360 aims to provide technical assistance to strengthen capacities to monitor and evaluate SBCC intervention for maternal health, family planning, tuberculosis, and HIV/AIDS of public program managers at national, state, and district levels. The Population Council will train a cadre of master trainers on M&E of SBCC activities at the national and state level who would further build capacity of human resources responsible for M&E of SBCC activities at the district level. This training manual has been prepared to address capacity building for M&E of SBCC interventions

Dietary protein and energy interations: an approach to optimizing dietary protein to energy ratio in walking catfish, Clarias batrachus

An 8 weeks feeding trial was conducted in a static indoor rearing system to investigate protein to energy ratio (PIE ratio) in walking catfish Clarias batrachus. Six fishmeal based diets of two protein levels (25 and 35%), each with three lipid levels (5, 10 and 15%) resulted in P/E ratios ranging from 13.57 to 21.97 mg protein kJˉ¹ gross energy (GE) were fed to 50 fish in triplicate. Fish were fed 6% of their body weight three times per day adjusted fortnightly. Significantly higher (p0.05) values of protein utilisation were found in between the both (higher and lower) protein diets. Higher lipid deposition (p<0.05) in whole body was observed with increasing dietary lipid level at each protein diet and as higher (p<0.05) for the lower protein diets. The study reveals that C. batrachus performed best the diet containing 35%, 17.06 kJ gˉ¹ and 20.55 mg protein kJ gˉ¹ GE protein, gross energy and P/E ratio respectively

Optimum dietary carbohydrate to lipid ratio in stinging catfish, Heteropneustes fossilis (Bloch, 1792)

A feeding trial of 8 weeks was conducted in a static indoor rearing system to investigate the optimum carbohydrate to lipid ratio (CHO:L ratio) in stinging catfish, Heteropneustes fossilis. Five iso-nitrogenous (35% crude protein) and iso-energetic (17.06 kJ gˉ¹ gross energy (GE)) fish meal based diets with varying carbohydrate to lipid (CHO:L g/g) ratios of 0.60, 0.98, 1.53, 2.29 and 3.44 for diets 1-5, were tested, respectively. The diets containing a fixed protein to energy ratio (P:E ratio) of 20.50-mg protein kJˉ¹ GE were fed to triplicate groups of 40 fish (per 70-L tank). Fish were fed 5% of their body weight per day adjusted fortnightly. Diet 1, containing 10% carbohydrate and 17% lipids with a CHO:L ratio of 0.60 produced the poorest (p<0.05) growth rates, feed and protein efficiency. Increasing carbohydrate content in the diets to 26% concomitant with a reduction in lipid content to 11% with a CHO:L ration of 2.29 of diet 5 significantly improved (p<0.05) growth rates, feed and protein efficiency. But did not differ with diet 4, containing CHO:L ratio 2.29. A further increase in dietary carbohydrate up to 31% and a decrease in lipids levels to 9% with a CHO:L ratio ranging from 2.29 to 3.44 (diet 4-5) did not significantly improve the fish performance. Apparent net protein utilisation (ANPU) of fish fed diet 5 was higher (p<0.05) than for diets 1 and 2 but did not differ from diets 3 and 4. Higher lipid deposition (p<0.05) in whole body was observed with decreasing dietary CHO:L ratios as increasing lipid levels. Whole body protein of fish fed varying CHO:L diets did not show any discernible changes among the dietary treatments. This study revealed that H. fossilis can perform equally well on diets containing carbohydrate ranging from 26 to 31%, with 9 to 11% lipid or at CHO:L g/g ratio of 2.29-3.44

Introduction of DMPA in public health facilities of Uttar Pradesh and Rajasthan: An evaluation

India is committed to achieving the goals of FP2020, which, besides substantially increasing new contraceptive users, also demands adopting a rights-based approach and ensuring easy access, choice, and good quality services. The contraceptive method mix in India has been dominated by female sterilization for a long time. No new contraceptive method has been added to the national family welfare program for decades. Use of injectable contraceptives was approved in 1994 in the private sector, but is still not part of the national program. Recently some initiatives have been taken to make Depo Medroxyprogesterone Acetate (DMPA) available through the public sector in some parts of the country. This project brief describes a study undertaken to document the initiatives taken to provide DMPA through public health facilities. Two such initiatives took place in Uttar Pradesh and Rajasthan. The study shows that acceptability of DMPA has remained strong despite many women’s reporting of side effects, and indicates that DMPA can be introduced safely in the public sector. Most stakeholders, doctors, and paramedics feel that DMPA should be included in the national family welfare program

Situation analysis of behavior change communication activities in Bihar: A step towards developing a comprehensive BCC strategy

A situation analysis undertaken by the Population Council in Bihar, India assessed a number of contributing factors to a behavior change communication (BCC) strategy. Social norms and practices can be changed if appropriate messages are delivered through a combination of communication channels including mass, mid-, and other media, coupled with improved interactions between frontline healthcare workers and target populations at family and community levels. The analysis notes that effective BCC strategy should be measured in terms of actual behavior change. Impact of BCC activities can be measured by immediate outputs and intermediate and final outcomes depending on implementation duration. The report discusses detailed examples of indicators that could be used for measuring BCC impact

Increasing choice of and access to family planning services via outreach in Rajasthan, India

This report documents a service evaluation of Marie Stopes (MS) India’s mobile outreach program in the state of Rajasthan, which was conducted by the Population Council between March and October 2012. This study was made possible through the United States Agency for International Development (USAID)-funded Support for International Family Planning Organizations–Marie Stopes International project. It provides important findings on the safety and effectiveness of MS India’s outreach program in expanding choice and access to long-acting reversible contraception methods and voluntary surgical permanent methods of contraception, as well as recommendations for MS India and other family planning programs to consider in scaling up and strengthening the provision of mobile outreach services. The study demonstrates the safety and effectiveness of providing tubal ligation and IUDS through MS India’s mobile outreach services in the state of Rajasthan, and the importance of using this service model to increase access and choices for poor men and women living in rural areas

Introduction of emergency contraception in Bangladesh: Using operations research for policy decisions

The Directorate of Family Planning, Bangladesh, the Population Council, Pathfinder International, and John Snow Incorporated collaborated to conduct this operations research study to assess the acceptability and feasibility of providing emergency contraception pills (ECP) as a backup support to existing family planning methods. The study demonstrated that all categories of health providers, including NGO outreach workers, could be effectively trained to provide ECP services. The study also demonstrated high acceptability of ECP and revealed that if used correctly, the success rate in avoiding unwanted pregnancy was extremely high. The positive findings of the study have helped the Ministry of Health and Family Welfare, Government of Bangladesh, to approve introduction of ECP in the National Family Planning Program. The present study thus also serves as a good demonstration of how operations research can contribute in policy decisions and how research findings can be translated into action
