When designing cluster-randomized trials (CRTs), one important consideration is determining the proper sample sizes across levels and treatment conditions to cost-efficiently achieve adequate statistical power. This consideration is usually addressed in an optimal design framework by leveraging the cost structures of sampling and optimizing the…

Because of the high cost, venue-based probability sampling of young men who have sex with men (YMSM) is largely inaccessible to social researchers. The aim of this study is to compare the feasibility of implementing geosocial networking application-based (GSNA) and venue-based probability sampling of young men who have sex with men. A…

Background: Obesity rates are higher in children with intellectual and developmental disabilities (DD) compared to typically developing (TD) children. In TD children, family-based (FB) interventions for obesity are the most effective interventions. Research addressing obesity interventions for children with IDD is limited. Method: We adapted a…

Regional Educational Laboratory Appalachia researchers developed the Cost-Feasibility Analysis (CFA) Toolkit to help education leaders estimate whether implementing supplemental online programs is affordable given a school or district's available resources. The CFA Toolkit guides users through a four-stage process that yields cost information that…

While mail surveys are common in many developed countries, it is still a new method in other, often less-developed countries. This study explores the feasibility of mail surveys in urban China. We conducted an experiment manipulating delivery method (regular mail vs. courier delivery service) and incentive payment (prepaid vs. no incentive) using…

A growing number of public schools have adopted reforms that increase the amount of time students spend in school. However, the potential costs of such reforms are not well understood. In this article, we report findings from a resource-cost study conducted in four schools that participated in the Massachusetts Expanded Learning Time Initiative.…

The case is based on an actual product introduction, and is designed to provide instruction on the new product development process. With the cost to launch new products estimated at least US $15 million and new product failure rates ranging from 40% to 80%, it is imperative that students learn how to determine the financial and market feasibility…

This is a first mixed-methods study, which created, adapted and tested the feasibility of a training programme targeted at parents, community professionals, specialist teachers and volunteers to provide advice on developmental stimulation for children with visual impairment in their homes in rural and urban settings of Malawi. The study followed…

This paper presents a role-play exercise and assignment that provides an active learning experience related to the system investigation phase of an SDLC. Whether using waterfall or agile approaches, the first SDLC step usually involves system investigation activities, including problem identification, feasibility study, cost-benefit analysis, and…
