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…

Bronhiālās astmas ārstēšanai izmantojamo medikamentu aprite "Benu aptiekā 2" 2015. gadā
2016
Astma ir izplatīta hroniska elpceļu iekaisuma slimība, kas skar gan bērnus, gan pieaugušos. To raksturo mainīgi un atkārtoti simptomi, atgriezeniska elpceļu obstrukcija un bronhu spazmas. Astmas ārstēšanas mērķis ir iegūt klīnisko kontroli un samazināt nākotnes risku pacientam. Šī darba mērķis ir izpētīt bronhiālās astmas ārstēšanai izmantojamo medikamentu apriti Benu aptiekā 2 Rīgā 2015. gadā un to atbilstību Global Initiative for Asthma (GINA) 2016. gada vadlīnijām. Astmas terapijā ārsti visbiežāk izraksta astmas kontrolējošos medikamentus. Pieprasītākais astmu kontrolējošais medikaments ir inhalējama glikokortikoīda un ilgstošas darbības β2 agonista kombinētais medikaments flutikazons/ s…
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…
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 …
Liikkeenjohdon konsultointi - nuori ja kasvava toimiala
1999
Liikkeenjohdon konsultoinnin professionaalistumista on Suomessa tutkittu vuosikymmenen puolivälissä. Tutkimuksen mukaan ala on nuori ja vain osittain järjestäytynyt. Konsulttien koulutustaso on kirjava, vaihtuvuus on suuri eikä alalle ole muodostunut markkinasuojaa. Monet ulkoiset muutostekijät luovat kuitenkin tarvetta professionaalistumisprosessin etenemiselle. Professio kuvaa joukkoa ihmisiä, joilla on samanlainen koulutuksellinen tausta, siihen liittyvä tiedeperusta ja näihin liittyvä yhteiskunnan hyväksyntä ammatillisine ja eettisine normistoineen. Artikkelissa käsitellään profession muodostumista liikkeenjohdon konsultoinnissa. Kirjoittaja näkee toimialan arvoketjuna. Sen muodostavat …
Eettinen organisaatiokulttuuri : yhteydet työhyvinvointiin ja työpaikan vaihtoihin
2015
The research investigated the associations between ethical organizational cul ture, ethical strain (stress caused by ethical dilemmas) and job turnover. The first study investigated differences in employees’ ethical strain and their evalua tions of the ethical culture of their organizations between a public sector city organization (n = 3,123), an engineering firm (n = 287) and a bank (n = 187). In the second study, the connections between resources and personal authority for ethical actions (one dimension of the ethical culture of an organization) and eth ical strain in social affairs and health services in a public sector city organization were analyzed at the work-unit (n = 142) level as…

Work Stressors and Intention to Leave the Current Workplace and Profession: The Mediating Role of Negative Affect at Work.
2022
The first aim of this study was to determine whether organisational constraints, interpersonal conflicts at work, workload and negative affect at work have a positive relationship with intention to leave a current job or profession. The second aim was to investigate whether negative affect at work mediates the relationship between work stressors and intention to leave a current job or profession. The study was a quantitative cross-sectional design in nature. Data were collected between March and April 2022. The sample consisted of 306 midwives working in the Polish public health service. The theoretical model was tested using structural equation modelling. The results confirmed positive dir…
