Despite the frequency with which obstetrics providers manage labor, evidence has emerged in the past few years challenging our historical understanding of normal labor progress over time. We are also confronted with the dearth of evidence to guide the optimal management of labor. With these data, we are presented with both the challenge of changing practice at the bedside and the opportunity fo...

— This paper focuses on the question of whether labor standards can affect comparative advantage in unskilled-labor-intensive goods in developing countries, and thereby influence trade flows. Using a Heckscher–Ohlin framework, the effects of low labor standards depend on the type of standard: Forced and child labor lead to an increase in the endowment of unskilled labor, and hence improve compa...

The study of labor flows across labor markets is a central ingredient in any discussion of labor market equilibrium. These labor flows help markets reach a more efficient allocation of resources. This paper surveys the economic analysis of immigration. It investigates the determinants of the immigration decision by workers in source countries and the impact of that decision on the host country'...

Preterm labor is responsible for a majority of cases of perinatal morbidity and deaths. Prevention of preterm labor is not usually possible; thus pharmacologic treatment is the only recourse available. Numerous agents have been used to treat preterm labor, but none has proved to be superior. This report reviews the current information available about the pharmacology of labor-inhibiting drugs a...

"This theoretical discussion of the migration transition in Asia develops a framework to understand the turning point from labor exporter to labor importer experienced by the Asian NIES [newly industrialized economies] (Hong Kong, Korea, Singapore and Taiwan). The author concludes that the NIEs' demand for labor curve shifted rapidly, primarily due to export-led growth of a labor-intensive cha...

Labor is a crucial resource in most organizations. In not-for-profit, public, and government services, it is common for labor to include unpaid volunteers. This article demonstrates how the volunteer labor assignment (VLA) problem is markedly different from traditional labor assignment (TLA) problems such as labor scheduling. One core difference pertains to the cost structure of labor, where TL...

Regional analgesia has become the most common method of pain relief used during labor in the United States. Epidural and spinal analgesia are two types of regional analgesia. With epidural analgesia, an indwelling catheter is directed into the epidural space, and the patient receives a continuous infusion or multiple injections of local anesthetic. Spinal injections are usually single injection...

OBJECTIVE Preterm labor is one of the common causes of prenatal morbidity and mortality. With considering the importance of preterm labor and lack of sufficient studies about the relationship between preterm labor and some factors such as cigarette smoking and opiate-using, the present study was designed. METHODS We performed this descriptive-analytic study on 988 pregnant women referring to ...
