Mobile diary for wellness management--results on usage and usability in two user studies.
2008
The prevalence of lifestyle-related health problems is increasing rapidly. Many of the diseases and health risks could be prevented or alleviated by making changes toward healthier lifestyles. We have developed the Wellness Diary (WD), a concept for personal and mobile wellness management based on Cognitive-Behavioral Therapy (CBT). Two implementations of the concept were made for the Symbian Series 60 (S60) mobile phone platform, and their usability, usage, and acceptance were studied in two 3-month user studies. Study I was related to weight management and study II to general wellness management. In both the studies, the concept and its implementations were well accepted and considered as…
Saikne starp stresu un darbaspējām māsām un medicīnas personālam
2018
Pētījuma mērķis tika sasniegts izpildot pētījuma uzdevumus, kuri iekļauj trīs pamatdaļas: 1. starptautiskas aptaujas validēšanu un pielāgošanu Latvijas populācijai; 2. aptaujas veikšanu medicīnas darbinieku vidē saskaņā ar starptautisku protokolu; 3. sasniegto atbilžu statistisko apstrādi un secinājumu veidošanu. Pētījuma hipotēzes: 1. Pastāv negatīva saikne starp darba stresu un darbaspējām medicīnas darbinieku vidē; 2. Darba vides stresa ietekme uz māsu un medicīnas darbinieku darbaspējām dažādās vecuma grupās ir atšķirīga. Izvirzītās hipotēzes apstiprinājās. Pētījuma rezultāti: Pētījuma kvalitatīvajā daļā tika paradītas atšķirības, anketas jautājumu izpratnē, starp latviski un krieviski …
Stress un izdegšana medicīnas un psiholoģijas studentiem
2022
Bakalaura darba pētījuma mērķis bija izpētīt uztvertā akadēmiskā stresa un akadēmiskās izdegšanas saistību medicīnas un psiholoģijas studentiem, kā arī noskaidrot vai pastāv nozīmīgas atšķirības starp medicīnas un psiholoģijas studentu uztvertā akadēmiskā stresa līmeni un akadēmiskās izdegšanas risku. Pētījumā piedalījās 66 respondenti, (59 sievietes, 7 vīrieši), vecumā no 19 līdz 46 gadiem (M=23,27; SD=22,24). Datu ievākšanai tika izmantotas divas aptaujas, Uztvertā akadēmiskā stresa aptauja (Perception of Academic Stress (PAS); Bedewy & Gabriel, 2015) un Maslakas izdegšanas sindroma aptauja- Studentu versija (Maslach Burnout Inventory-Student Survey (MBI-SS); Schaufeli, Martinez, Pinto, S…
Medicīnas studentu empātijas, uztvertā stresa un subjektīvās labklājības saistības
2020
Medicīniskā izglītība ir plaši zināma kā lielus resursus pieprasošs process, kas var izraisīt dažādas psiholoģiskās problēmas, kas, savukārt, var samazināt studentu empātijas un apmierinātības ar dzīvi līmeni. Bakalaura darba mērķis bija apkopot šobrīd zināmo informāciju par empātiju, uztverto stresu, subjektīvo labklājību un šo konstruktu saistībām; noteikt, vai starp medicīnas studentu dzimumu un studiju kursu pastāv atšķirības šo trīs mainīgo mērījumu rezultātos; noskaidrot, vai starp tiem pastāv saistības; balstoties uz saistību ciešumu, atlasīt tos mainīgos lielumus, kas vislabāk izskaidro apmierinātību ar dzīvi šajā izlasē un šajā pētījumā. Pētījuma izlasi veido 216 studenti no medicī…
Sex-specific effects of natural and sexual selection on the evolution of life span and ageing in Drosophila simulans
2014
Summary Variation in the strength of age-dependent natural selection shapes differences in ageing rates across species and populations. Likewise, sexual selection can promote divergent patterns of senescence across the sexes. However, the effects of these processes on the evolution of ageing have largely been considered independently, and interactions between them are poorly understood. We use experimental evolution to investigate how natural and sexual selection affect life span and ageing in Drosophila simulans. Replicate populations were evolved under lifetime monogamy (relaxed sexual selection) or lifetime polyandry (elevated sexual selection) and at one of two temperatures, 25 °C (rela…
Antioxidant effect of melanoidins after induction of oxidative stress in isolated rat hepatocytes
2002
Se estudia el efecto de las melanoidinas en el estrés oxidativo inducido por adriamicina en hepatocitos aislados de rata. Las melanoidinas presentan un efecto protector, incrementando la viabilidad celular y protegiendo a los lípidos y a las proteínas del estrés oxidativo Melanoidins have a protective effect over macromolecules. They increase cellular viability and protect lipids and proteins from oxidative stress
Ecophysiological and molecular processes involved in water stress memory in pea: from gene expression regulation to plant hydromineral nutrition
2022
Climate change induces increasingly frequent periods of water deficits during the crop cycle. These periods of water stress negatively impact the plant, notably by limiting the availability of resources (water, mineral elements) and by limiting carbon fixation by the plant. In this context, several studies highlighted the beneficial effect of “priming” of a first stress on the response to a second stress by the induction of a transcriptional memory. This memory depends on epigenetic modifications implemented during the first stress. These modifications can regulate the expression of genes known as “memory genes” which have been characterized in the aerial parts of Arabidospsis and maize. Ho…
A Group Intervention to Promote Resilience in Nursing Professionals: A Randomised Controlled Trial
2022
In this study, a new group intervention program to foster resilience in nursing professionals was tested for efficacy. In total, 72 nurses were recruited and randomised to either an intervention condition or to a wait list control condition. The study had a pre-test, post-test, follow-up design. The eight-week program targeted six resilience factors: cognitive flexibility, coping, self-efficacy, self-esteem, self-care, and mindfulness. Compared to the control group, the intervention group reported a significant improvement in the primary outcome mental health (measured with the General Health Questionnaire) from pre-test (M = 20.79; SD = 9.85) to post-test (M = 15.81; SD = 7.13) with an est…
Psychosocial Safety Climate: A New Work Stress Theory and Implications for Method
2019
This book responds to a public health priority (Whiteford et al., 2013) and a call from the WHO (2016), ILO (2016) and OECD (2012) to prevent and manage mental ill-health and promote health and well-being by drawing attention to the connection between work and mental health. By demonstrating a link between work factors and mental health-related issues, this book will provide public policy makers with evidence needed to shift policy attention to create mentally healthy workplaces and move investment of health, compensation, and insurance funding into proactive prevention strategies rather than costly treatments, medications, therapy, and hospitalisation. Ensuring workplaces globally have the…
Postnatal predator exposure reduces fear and anxiety behaviors in adult mice
2010
Poster; Predator cues are very efficient to induce fear in rodents but most studies use adult subjects and not pups. Nevertheless, a perinatal stress can have a significant effect on behavior and on physiology at adulthood. An early stress (foot shock, restraint, mother separation) is able to modulate behaviors later and the aim of this study was to examine if the synthetic predator odor 2,3,5-trimethylthiazoline (TMT) presented to neonates modifies fear and anxiety-related behaviors in adult female mice.
