A bibliographical review of the most outstanding studies regarding the assessment of library services, establishing their origin and development since the decade of the sixties. Chronologically, the contributors which the author considers to be classics, or more significant regarding the features included in the assessment of library services, some of which address the assessment, as well as ot...

The ability to model ‘‘new’’ (nitrate-based) production is crucial to predicting the ocean’s role in the global carbon cycle. The ability to model the distribution of high-nutrient/low-chlorophyll (HNLC) areas is particularly important in this regard. Here I draw together three elements that appear to be necessary for constructing the required model: (1) iron limitation of algal growth rates as...

Exposure to solar radiation substantially decreased the strong copper-complexing capacity of samples collected from the organic-rich Cape Fear estuary, North Carolina. Samples exposed to natural sunlight for 1–2 d experienced a loss of strong Cu ligand (modeled at fixed K9CuL 5 1013.5) ranging from 15–33%, and .90% using long-term exposures under controlled conditions with a Xe arc solar simula...

Today, in part because of the work done by Ajzen, Fishbein and their colleagues, the core of their theory seems obvious individuals are more likely to perform the behaviours that they feel positive toward and intend to perform. Many models of behaviour share the assumption that behaviour results from a reasoned process, where individuals consider their options, evaluate the consequences and mak...

The response of the heterotrophic bacterial community to iron addition was determined during the mesoscale iron-enrichment experiment conducted in the eastern equatorial Pacific during May–June 1995 (IronEx II). Bacterial abundance and 3H-leucine incorporation rates were measured for samples collected from the middle of the mixed layer (15 m) over the course of the iron-induced phytoplankton bl...

Title of Dissertation: CHARACTERIZATION OF PLANT ROOT CELL WALL STRUCTURAL CHANGES DURING DECOMPOSITION Kathryn Ella White, Doctor of Philosophy, 2015 Dissertation directed by: Professor Frank J. Coale, Department of Environmental Science and Technology Plant roots are important contributors of organic carbon compounds for soil organic matter (SOM) formation, particularly hemicellulose, cellulo...

The effects of added Si and Fe on the rate of silicic acid uptake were examined during two cruises to the equatorial Pacific upwelling zone between 110uW and 140uW. Maximum uptake rates of Si (Vmax) were highly consistent with a mean of 0.026 6 0.007 h21(n 5 29), implying maximum diatom growth rates of ,0.6 d21. Halfsaturation constants for Si uptake (KS) also showed little variance, averaging ...

This article links spatial indicators of two demographic innovation waves to historical and contemporary covariates of both a socio-economic and a cultural nature. The two waves of innovation correspond respectively to the so called “first” and “second” demographic transitions (FDT, SDT). A connection is made between the emergence of spatial demographic patterns and A.J. Coale’s three precondit...

IN AN ARTICLE published in this journal in 1997, drawing on data from China’s 1982 One-per-Thousand-Population Fertility Survey, I argued that the highfertility regime existing before China’s nationwide family planning campaign was introduced could have involved deliberate fertility control. James Lee, Feng Wang, and Cameron Campbell reached a similar conclusion (Wang, Lee, and Campbell 1995; L...

Nonconsumptive mortality of mesozooplankton in Lake Constance was directly estimated by collecting dead zooplankton with sediment traps. Patterns of zooplankton sedimentation observed in the sediment trap reflected the population dynamics in the pelagic zone. The migration of Cyclops vicinus toward the sediment (where they spend their diapause) at the end of May resulted in a pronounced occurre...
