The diversity-productivity relationship has not been studied as extensively in forests as in other ecosystems. We address this gap in our knowledge by examining the relationship of productivity (primarily the periodic annual increment in aboveground biomass, but also the mean annual increment) with five species diversity indices, stand, and environmental factors. We used 967 naturally regenerat...

BACKGROUND ClinicalConnect, a federated clinical viewer for South West Ontario, Canada, launched a mobile interface in June 2012. OBJECTIVE The aim of the study was to assess usability of the mobile interface and the perceived impact on productivity of health care providers and quality of healthcare delivery. METHODS A survey was conducted using the System Usability Scale (SUS) and question...

Open, Grassand Forb-Dominated (OGFD) ecosystems, including tundra, tropical grasslands and savanna, provide habitat for both wild and domesticated large ungulate herbivores. These ecosystems exist across a wide temperature gradient from the Arctic regions to the Equator, but are confined to a narrow set of moisture conditions that range from arid deserts to forest-dominated systems. Primary pro...

Monthly mean global green leaf area and photosynthetically active radiation estimated from observations made from several geostationary and polar orbiting satellites were used to estimate potential, (i.e., unstressed) gross primary productivity of terrestrial vegetation from 1982 to 1990. Mean annual gross primary productivity was estimated to be about 179.9 q1.6 Pg C (1 Pg = 1015 g)o Grasses a...

[1] We illustrate the mechanisms controlling the spatial patterns of biological productivity in the Southern Ocean using a coupled, physical-biogeochemical-ecological model. The model captures a belt of enhanced export production, figuratively termed as the Antarctic Circumpolar Productivity Belt. As observed, there is a maximum in silica export to the south of the peak in the organic carbon ex...

One of the stylized facts from the literature on international activities of heterogeneous firms is the existence of a positive exporter productivity premium on average, exporting firms are more productive than firms that sell on the national market only. In this paper, we look at the productivity distribution of both exporting and non-exporting firms in German manufacturing industries. We reco...

INTRODUCTION Lost productivity accounts for a significant part of the costs caused by gastrointestinal symptoms. We aimed to describe selfreported productivity in patients presenting with dyspepsia. MATERIAL AND METHODS Data were sourced from a randomized, double-blinded study of two weeks of esomeprazole 40 mg or placebo in 805 primary-care patients with uninvestigated dyspepsia. Work produc...

With statistics pointing to nearly 100% adoption of mobile phones in developed countries and nearly 50% adoption worldwide, mobile phones have become a pervasive portion of our information and communications infrastructure. In many developing countries, mobiles are becoming an important platform for delivering information services. Yet in spite of its rapid adoption, does this mean that cell ph...
