TL;DR: In this paper, the potential for anaerobic ammonium oxidation coupled to iron(III) reduction, known as Feammox, was investigated in tropical upland soils. And the results showed that Feammoxide can fuel nitrogen losses in ecosystems rich in poorly crystalline iron minerals with low or fluctuating redox conditions.
Abstract: The oxidation of ammonium is a key step in the nitrogen cycle, regulating the production of nitrate, nitrous oxide and dinitrogen. In marine and freshwater ecosystems, anaerobic ammonium oxidation coupled to nitrite reduction, termed anammox, accounts for up to 67% of dinitrogen production 1‐3 . Dinitrogen production through anaerobic ammonium oxidation has not been observed in terrestrial ecosystems, but the anaerobic oxidation of ammonium to nitrite has been observed in wetland soils under iron-reducing conditions 4,5 . Here, we incubate tropical upland soil slurries with isotopically labelled ammonium and iron(III) to assess the potential for anaerobic ammonium oxidation coupled to iron(III) reduction, otherwise known as Feammox 6 , in these soils. We show that Feammox can produce dinitrogen, nitrite or nitrate in tropical upland soils. Direct dinitrogen production was the dominant Feammox pathway, short-circuiting the nitrogen cycle and resulting in ecosystem nitrogen losses. Rates were comparable to aerobic nitrification 7,8 and to denitrification 9 , the latter being the only other process known to produce dinitrogen in terrestrial ecosystems. We suggest that Feammox could fuel nitrogen losses in ecosystems rich in poorly crystalline iron minerals, with low or fluctuating redox conditions.

Journal ArticleDOI
TL;DR: In this article, a simple and cost effective methodology for the assessment of soil quality at a watershed scale, based on zones of specific functional interest, is proposed, which would provide information about the status of the soil resources, correlate soil quality with management and aid with the development of sustainable management practices.

TL;DR: Data demonstrate the ideal worker norm is pervasive and powerful, even as employees begin critically examining expectations regarding work time that have historically privileged men.
Abstract: This article integrates research on gendered organizations and the work-family interface to investigate an innovative workplace initiative, the Results-Only Work Environment (ROWE), implemented in the corporate headquarters of Best Buy, Inc. While flexible work policies common in other organizations "accommodate" individuals, this initiative attempts a broader and deeper critique of the organizational culture. We address two research questions: How does this initiative attempt to change the masculinized ideal worker norm? And what do women's and men's responses reveal about the persistent ways that gender structures work and family life? Data demonstrate the ideal worker norm is pervasive and powerful, even as employees begin critically examining expectations regarding work time that have historically privileged men. Employees' responses to ROWE are also gendered. Women (especially mothers) are more enthusiastic, while men are more cautious. Ambivalence about and resistance to change is expressed in different ways depending on gender and occupational status.

TL;DR: In this paper, the authors proposed and tested two new antecedent variables (psychological capital and supervisor support climate) to test thriving at work by linking it to a theoretically important personal outcome variable (self-development).
Abstract: Summary Thriving at work is a positive psychological state characterized jointly by learning and vitality. Conventional wisdom and some initial research indicate that such thriving benefits both employees themselves and their organizations. This study specifically tests thriving at work by linking it to a theoretically important personal outcome variable (self-development), refining its relationship with agentic work behaviors (task focus and heedful relating), and proposing and testing two new antecedent variables (psychological capital and supervisor support climate). Using structural equation modeling on a sample of 198 dyads (employees and their supervisors), strong support was found for the theory-driven hypothesized relationships. The results contribute to a better understanding of positive organizational scholarship and behavior in general and specifically to the recently emerging positive construct of employees' thriving at work.
