BACKGROUND HIV has become a chronic manageable infection in the developed world, and early and lifelong treatment has the potential to significantly reduce transmission rates in the community. A skilled and motivated HIV medical workforce will be required to achieve these health management and prevention outcomes, but concerns have been noted in a number of settings about the challenges of recr...

nowadays both part-time as well as regular employees are working in many organizations of bangladesh. though many studies have been conducted to know the motivation status of regular employees but no study is found that addressed motivations status of both regular and part-time employees of bangladesh. thus, this study is conducted on 300 regular and part-time employees of bangladesh to know th...

The increased global exchange of merchandise, services, and capital is a key characteristic of the contemporary business environment. International firms position themselves to gain competitive advantage from opportunities offered in this larger and more open economic system. Similarly, governments reap rewards from firms that establish operations within their borders. There are strong argument...

People primarily pursue long-term goals, such as exercising, to receive delayed rewards (e.g., improved health). However, we find that the presence of immediate rewards is a stronger predictor of persistence in goal-related activities than the presence of delayed rewards. Specifically, immediate rewards (e.g., enjoyment) predicted current persistence at New Year's resolutions whereas delayed re...

Pursuing personal goals for delayed rewards (e.g., exercising to improve health) often provides consumers with immediate rewards (e.g., a fun workout) in addition to the delayed rewards they receive. With regard to health and academic goals, we find that attending to the immediate rewards of health and academic activities increases persistence in these activities to a greater extent than attend...

We consider a multi-armed bandit problem in a setting where each arm produces a noisy reward realization which depends on an observable random covariate. As opposed to the traditional static multi-armed bandit problem, this setting allows for dynamically changing rewards that better describe applications where side information is available. We adopt a nonparametric model where the expected rewa...

Online labor markets such as Amazon Mechanical Turk (MTurk) have emerged as platforms that facilitate the allocation of productive effort across global economies. Many of these markets compensate workers with monetary payments. We study the effects of performance-contingent financial rewards on work quality and worker effort in MTurk via two experiments. We find that the magnitude of performanc...

It has proved surprisingly hard to generalize from the rapid advances in our understanding of fundamental cognitive mechanisms to people’s real-life behavior. This is in part because the impact such mechanisms have in real life depends on how they dynamically interact with other aspects of our mental state and environmental circumstances. I will present recent work uncovering one such dynamical...
