Zest and work

Abstract: Zest is a positive trait reflecting a person's approach to life with anticipation, energy, and excitement. In the present study, 9803 currently employed adult respondents to an Internet site completed measures of dispositional zest, orientation to work as a calling, and satisfaction with work and life in general. Across all occupations, zest predicted the stance that work was a calling (r = .39), as well as work satisfaction (r = .46) and general life satisfaction (r = .53). Zest deserves further attention from organizational scholars, especially how it can be encouraged in the workplace. Copyright © 2009 John Wiley & Sons, Ltd.

The Impact of Atmospheric Nitrogen, Phosphorus, and Iron Species on Marine Biological Productivity

Abstract: Marine chemists have long been concerned with the geochemical cycling of trace species in the ocean and with evaluating the sources, sinks, and transport paths of chemicals through the marine system. In recent years there has been a growing realization that rivers — previously believed to be the primary input path for materials entering the ocean — may be equalled and even surpassed in some cases by other transport paths and sources. Recent investigations of hydrothermal vents and submarine volcanism have highlighted the importance of these sources on the ocean floor for a number of substances in the ocean. Over the past ten years it has become apparent that the atmosphere can also be an important transport path for many substances entering the sea. Indeed, one of the primary objectives of this Advanced Study Institute is an evaluation of the importance of air/sea exchange processes in controlling or affecting the concentrations of a wide variety of marine organic and inorganic substances.

Minimal NFA problems are hard

Abstract: Finite automata (FA’s) are of fundamental importance in theory and in applications. The following basic minimization problem is studied: Given a DFA (deterministic FA), find a minimum equivalent no...

Mesopelagic zone ecology and biogeochemistry - a synthesis

Abstract: The mesopelagic zone is the oceanic region through which carbon and other elements must pass in order to reach deeper waters or the sea floor. However, the food web interactions that occur in the mesopelagic zone are difficult to measure and so, despite their crucial importance to global elemental cycles, are not very well known. Recent developments in technology and new approaches have advanced the study of the variability in and controls upon the distribution and diversity of organisms in the mesopelagic zone, including the roles of respiration, recycling, and repackaging of particulate and dissolved organic material. However, there are remarkably few syntheses of the ecology and biogeochemistry of the microbes and metazoa that permanently reside or habitually visit this ‘twilight zone’. Without this synthesis, it is difficult to assess the impact of ongoing changes in ocean hydrography and chemistry, due to increasing atmospheric carbon dioxide levels, on the biological carbon pump. This paper reviews what is known about the distribution of microbes and metazoa in the mesopelagic zone in relation to their activity and impact on global biogeochemical cycles. Thus, gaps in our knowledge are identified and suggestions made for priority research programmes that will improve our ability to predict the effects of climate change on carbon sequestration.
