Resource productivity and returns to scale in school-based mouthrinsing programs

Community Dentistry and Oral Epidemiology
N J Doherty

Abstract

The viability of community dental programs is influenced by various factors, including costs and effectiveness. Costs, in turn, are influenced by the prices and productivity of resources, and variations in these will influence not only comparisons among programs providing a homogeneous service but also any conclusions that can be drawn about cost-effectiveness. This paper eliminates wage effects and examines resource productivity and returns to scale in relationship to the size of a group of school-based mouthrinsing programs. The research questions were to determine: 1) whether the programs exhibit increasing, decreasing, or constant returns to scale, and 2) the productivity of labor and capital. Data from 14 programs in the US were pooled for 2 yr to yield 28 observations. The production relationship between output (numbers of participants) and inputs (labor and capital) was specified in a Cobb-Douglas model. Findings were that 1) the programs exhibited decreasing returns to scale (P less than 0.01); and 2) the average and marginal productivities of labor and capital declined (P less than 0.001). The implications of these findings are that, with equal wages and homogeneous labor, the average cost of mouthrinsing per participa...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
