It is widely believed in the literature that inventory ‡uctuations are destabilizing to the economy. This paper re-assesses this view by developing an analyticallytractable general-equilibrium model of inventory dynamics based on a precautionary stockout-avoidance motive. The model’s predictions are broadly consistent with the U.S. business cycle and key features of inventory behavior, includin...

Theoretical models have been ambiguous on the relationship between industry competition and inventory holdings of manufacturing firms. Facing competition, on the one hand, firms may desire to hold more inventory to avoid losing sales to competitors; on the other hand, firms strive to improve inventory turns to control costs and stay competitive. Using U.S. Census data on manufacturing industrie...

In this work we deal with multilevel integrated distribution problems and in particular, we analyse the management of inventories of final goods in the distribution system. We present a survey of methods proposed in the recent literature devoted to the integration of inventory management systems. Starting from the concept of echelon inventory position we present an approach for the optimal flow...

BACKGROUND AND AIM: Protective equipment, such as lead aprons and thyroid shields, is effective in reducing patient radiation. This study was conducted for evaluation the use of thyroid shields and lead aprons in dental offices, in Kerman, Iran, in June 2014.METHODS: In this descriptive-analytical study, 106 dental offices with active X-ray machines were evaluated in Kerman. The information was...

In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...

OBJECTIVES This report presents data on the availability of pediatric services, expertise, and supplies for treating pediatric emergencies in U.S. hospitals. METHODS Data in this report are from the Emergency Pediatric Services and Equipment Supplement (EPSES), a self-administered questionnaire added to the 2006 National Hospital Ambulatory Medical Care Survey (NHAMCS). NHAMCS samples nonfede...

Health technology, according to WHO is the application of organized knowledge and skills in the form of devices, medicine, vaccines, procedures and systems development to solve a health problem and improve quality of lives4. When used in this paper, the term healthcare technology means the different types of devices or equipment used in health facilities. Its encompasses: medical equipment for ...

A community-based immunization coverage survey is the standard way to estimate effective vaccination delivery to a target population in a region. Accompanying serosurveys can provide objective measures of protective immunity against vaccine-preventable diseases but pose considerable challenges with respect to specimen collection and preservation and community compliance. We performed serosurvey...
