项目摘要
DESCRIPTION (provided by applicant): Africa is experiencing a dramatic epidemiological transition driven in opposite directions by continuing improvements in the management of traditional infectious diseases, concurrent exploding sexually transmitted infection and TB epidemics, and swift increases in the prevalence of chronic non-communicable diseases. With the following specific aims, this career development application fits into my long-term goal to contribute to understanding and eventually controlling pandemic sexually transmitted infections in Africa. (1) To measure and understand the important component systems of a population affected by sexually transmitted infections through empirical investigation of hypotheses that relate core groups, concurrency in sexual relationships and migration to the transmission and spread of sexually transmitted infections. (2) To modify, enhance and build mathematical/computational models to represent and investigate populations affected by sexually transmitted infections by: 1) continuing to adapt Bayesian melding methods that account for uncertainty in model inputs and outputs to work with UNAIDS's non-age-specific estimation and projections package (EPP) model; 2) to adapt and implement similar methods to work with a sexually transmitted infection-enabled age-specific cohort component projection model; 3) to improve my existing sexually transmitted infection-enabled microsimulator by: a) adding new modules to handle social, sexual and migrant networks, b) adding new procedures based on Bayesian melding to i) account for uncertainty, ii) put reasonable limits on outputs, iii) produce predictive distributions for outputs, and iv) provide a standard, reproducible method to calibrate the simulator. (3) To simulate populations affected by sexually transmitted infections to understand and predict the overall effects of interventions. There are three proximate determinants of an infectious disease epidemic, the transmission probability, the contact structure, and the duration of infectiousness suggested by the relationship R0 = f3 c d for the number of secondary cases produced by a case. The simulator will be used to explore the relationships between these and the dynamics of sexually transmitted infection epidemics. Insight gained through this process will be used to simulate and prioritize possible real interventions. I have experience with this type of investigation and some of the skills necessary to address these specific aims. The career development component of this application is designed to expand my minimal knowledge and skills in three specific areas that are necessary to address these aims: 1) social network theory and modeling methods, 2) mathematical statistics and Bayesian statistics in particular, and 3) modem up-to-date software algorithm design and computer programming skills.
描述(由申请人提供):非洲正在经历一场戏剧性的流行病学转变,这是由传统传染病管理的持续改善、同时爆发的性传播感染和结核病流行以及慢性非传染性疾病流行率的迅速增加所推动的。这个职业发展申请具有以下具体目标,符合我的长期目标,即为了解并最终控制非洲大流行性传播感染做出贡献。(1)通过对核心群体、同时发生性关系和移徙与性传播感染的传播和扩散之间关系的假设进行实证调查,衡量和了解受性传播感染影响的人口的重要组成系统。(2)修改、加强和建立数学/计算模型,以代表和调查受性传播感染影响的人口,方法是:1)继续采用贝叶斯融合方法,考虑到模型投入和产出的不确定性,以配合艾滋病规划署的不分年龄的估计和预测包模型; 2)调整和实施类似的方法,以使用性传播感染启用的年龄特异性队列组件预测模型; 3)通过以下方式改进我现有的性传播感染启用的微模拟器:a)增加新的模块来处理社会、性和移民网络,B)增加基于贝叶斯融合的新程序,以i)考虑不确定性,ii)对输出施加合理的限制,iii)产生输出的预测分布,以及iv)提供标准的、可再现的方法来校准模拟器。(3)模拟受性传播感染影响的人群,以了解和预测干预措施的总体效果。传染病流行有三个最直接的决定因素,即传播概率、接触结构和传染性持续时间,其关系式为R 0 = f3 c d,即一个病例产生的继发病例数。该模拟器将用于探索这些与性传播感染流行病动态之间的关系。通过这一进程获得的见解将用于模拟可能的真实的干预措施并确定其优先次序。我有这类调查的经验和一些必要的技能,以解决这些具体目标。本申请的职业发展部分旨在扩展我在三个特定领域的最低知识和技能,这些领域是实现这些目标所必需的:1)社会网络理论和建模方法,2)数理统计和贝叶斯统计,特别是3)现代最新的软件算法设计和计算机编程技能。
