Expression Patterns of Key Hormones Related to Pea (Pisum sativum L.) Embryo Physiological Maturity Shift in Response to Accelerated Growth Conditions

2019

Protocols have been proposed for rapid generation turnover of temperate legumes under conditions optimized for day-length, temperature, and light spectra. These conditions act to compress time to flowering and seed development across genotypes. In pea, we have previously demonstrated that embryos do not efficiently germinate without exogenous hormones until physiological maturity is reached at 18 days after pollination (DAP). Sugar metabolism and moisture content have been implicated in the modulation of embryo maturity. However, the role of hormones in regulating seed development is poorly described in legumes. To address this gap, we characterized hormonal profiles (IAA, chlorinated auxin…

A review of the importance of mineral nitrogen cycling in the plant-soil-microbe system of permafrost-affected soils : changing the paradigm

2022

The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in favor of organic N compounds is based on the observation that net N mineralization rates in these cold climates are negligible. However, we find here that this perception is wrong. By synthesizing published data on N cycling in the plant-soil-microbe system of permafrost ecosystems we show that gross ammonification and nitrification rates in active layers were of similar magnitude and showed a similar dependence on soil organic carbon (C) and total N concentrations as observed in temperate and tropical systems. Moreover, high protein depolymerization rates and only marginal effects of C:N stoichiomet…

Should I stay or should I go? Physical education teachers' career intentions

2014

Purpose: This study investigated Finnish physical education (PE) teachers’ intentions to leave the profession and the reasons behind them. Method: A large sample (N ¼ 808) of PE teachers who graduated between 1980 and 2008 (432 women, 376 men) answered a modified job satisfaction and teacher follow-up questionnaire that elicited career perceptions, intentions, and current work duties. Results: In this sample, 26% of the respondents were contemplating leaving their jobs as PE teachers and an additional 13% were actually in the process of transferring from PE teaching but planned to remain in school teaching. To determine the reasons for considering leaving the PE teaching profession, princip…

Career intentions of Australian physical education teachers

2015

The purpose of this study was to investigate Australian physical education (PE) teachers’ career intentions and factors influencing their intentions. A sample (N = 234) of Western Australian PE teachers responded to a questionnaire determining PE teachers’ work and the primary motivators for intention to leave the profession. Half (51.3%) of the respondents wanted a change from their current PE teacher job and 39.8% were intending to leave PE teaching. The most frequent reasons for wanting to leave PE related to: non-use of expertise, workload, school administration, and lack of opportunities for personal and professional development. Consideration should be given to mediation strategies th…

Investigation on the Nitrogen Metabolism of Spruce Needles in Relation to the Occurrence of Novel Forest Decline

1988

Summary In order to obtain information on the nitrogen metabolism of undamaged and damaged spruce ( Picea abies ), investigations were performed in 1985 and 1986 on the activity of glutamine synthetase and on the content of free ammonium and soluble proteins in spruce needles. In addition, the chlorophyll content was determined. Needles from the second needle year and the seventh whorl were used. The investigations were carried out in pair comparison on a 20-year-old spruce plantation and in comparison with damage classes on an 80-year-old spruce plantation. Both the pair comparison and the contrasting of different damage groups show an unequivocal decrease of the chlorophyll content correl…

A new approach to stress of conscience's dimensionality : Hindrance and violation stressors and their role in experiencing burnout and turnover inten…

2023

Aims To identify a valid, longitudinally invariant factor model for stress of conscience and to investigate how stress of conscience dimensions associate with burnout and turnover intentions. Background There has been a lack of consensus about the number and content of stress of conscience dimensions, and a lack of longitudinal studies on its development and outcomes. Design A longitudinal, person-centred survey study using the STROBE checklist. Methods Healthcare personnel (n = 306) rated their stress of conscience in 2019 and 2021. Longitudinal latent profile analysis was used to identify different subgroups based on the employees' experiences. These subgroups were then compared in terms …
