A Changing Media Landscape. Science, the Public and the Press: The Case of Climate Change
2013
Economic restructuring in the media industry has eliminated many professional journalists’ jobs, reductions that may have been hardest on specialized journalists reporting areas like science, technology, economics, or international affairs. This makes audiences even more dependent on new, often social, media for scientific information. The concept of «critical science literacy» is introduced as a way to capture the skills needed to navigate science news in the evolving media landscape. While these same skills were needed to make sense of science in the «old» media world as well, the contemporary shift resulting in attenuation of authoritative journalistic voices is likely to continue, deman…
Effect of temperature rising and ocean acidification on reproductive success of thermophilic sea urchin Arbacia lixula

Bean goose migration shows a long-term temporal shift to earlier spring, but not to later autumn migration in Finland
2023
Ilmastonmuutos vaatii eliöitä mukauttamaan perinnöllisiä tai opittuja käyttäytymismallejaan muuttuviin ympäristöolosuhteisiin. Erityisen alttiita muutoksille voi olla erilaisten habitaattien välillä muuttavat linnut, joiden selviytyminen on yhteydessä muuton onnistuneeseen ajoittamiseen. Tässä tutkimuksessa käytimme metsähanhesta (Anser fabalis) avoimeen lintutietopalveluun, Tiiraan (tiira.fi – BirdLife Suomi), kerättyjä havaintoja selvittääksemme, onko lajin muuton ajoituksessa tapahtunut muutosta viimeisten 40 vuoden aikana. Lisäksi selvitimme ajoituksen yhteyttä muuton aikaiseen suursäätilaan käyttämällä Pohjois-Atlantin suursäätilaa kuvaavaa NAO-indeksiä. Tutkitulla ajanjaksolla 1978–20…
Implementation and Outcomes of Lay Health Worker–led Self-management Interventions for Long-Term Conditions and Prevention: A Systematic Review
2019
The aim of this study was to systematically review lay health worker (LHW)–led self-management interventions for adults with long-term conditions to see how the interventions have been implemented and to compose a synthesis of research findings, taking into consideration the intervention components that have been applied. We conducted systematic searches for articles published between January 2010 and December 2015 in five databases: Cochrane, MEDLINE, CINAHL, PsycINFO, and Web of Science. Forty original studies were found that met the inclusion criteria: self-management with diabetes (n = 29), cardiovascular diseases (n = 8), and those at risk of cardiovascular diseases (n = 3). These cons…
Motivational Regulations Across the Stages of Change for Exercise in the General Population of Monterrey (Mexico)
2018
Few studies have examined exercise adherence in the Mexican population using self-determination theory proposals and the stages of change model. The objectives of this study were:(a) to translate and adapt the Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3) to Mexican Spanish and examine its internal consistency and factorial structure (six dimensions); and (b) to analyse variations in behavioral regulations using the stages of change model. This study included 530 participants between 11 and 76 years old who lived in the metropolitan area of the city of Monterrey, Nuevo Leon, Mexico. The Mexican version of the BREQ-3 presented an acceptable six-factor model that agrees with the …
From Country Girl in Southern Finland to Longitudinal Research into Alternatives to Aggression and Violence
2021
Lea Pulkkinen, born in Finland in 1939, is Emerita Professor of Psychology at the University of Jyväskylä (Finland). She is best known for creating the ongoing Jyväskylä Longitudinal Study of Personality and Social Development (JLSPSD). The study was specifically intended to test the hypothesis that the human brain allows for more variation in behavior than the simple ‘fight or flight’ response observed in animal studies of aggression. She further hypothesized that humans’ capacity for cognitive control over emotional behavior was the key factor involved in controlling aggressive behavior. These hypotheses led her to devise an impulse control model to depict behavioral alternatives, which s…
Habit and physical activity: Theoretical advances, practical implications, and agenda for future research
2019
Abstract Objective Understanding habits may inform intervention development aimed at promoting physical activity maintenance for long-term health. In the present article, I review theory and research on habits applied to physical activity. I provide an overview of contemporary conceptualizations of habit and habit theory; address whether or not physical activity can be habitual; review perspectives on how physical activity habits develop; summarize research on effects of physical activity habits; identify intervention strategies effective in promoting physical activity habits; and propose an agenda for future research on physical activity habits. Design and Methods Conceptual and narrative …

Zivju sabiedrības sezonālās izmaiņas Liepājas ostas akvatorijā saimnieciskās darbības ietekmē
2021
Darbā analizēta Liepājas ostas akvatorijas zivju sabiedrība, tās sezonālās izmaiņas, un to galvenie ietekmējošie faktori. Datu ievākšana, veicot kontrolzveju ar zinātniskajiem tīkliem trīs gadu garumā, četrās sezonās (rudens, ziema, pavasaris, vasara) sniedz precīzu ieskatu par zivju sugu sezonālajām izmaiņām. Papildus ievāktie hidroloģiskie dati ļauj spriest par galvenajiem ietekmējošajiem faktoriem. Darbu vēl unikālāku padara vienā no pētījuma posmiem veiktā ostas padziļināšana, izceļot grunti, kas ļauj ne tikai novērtēt papildus faktoru ietekmi uz zivju sugu mainību, bet izdarīt secinājumus arī par saimnieciskās darbības ietekmi uz zivju sabiedrību akvatorijā, novērot ostas ekosistēmas a…
Estimation de la différence de température entre la forêt et les sites ouverts dans le Jura
2017
International audience; Cet article porte sur la modélisation statistique des différences qui apparaissent entre la température observée en forêt et en site ouvert. Pour ce faire, nous utilisons un corpus de 29 couples de stations situées à faible distance l'une de l'autre dans les deux milieux et localisés dans le Jura (France). Les températures minimales (tn) et maximales (tx) ont été acquises de décembre 2014 à octobre 2015. La modélisation est fondée sur un modèle de régression où les variables explicatives sont deux variables temporelles relatives aux conditions atmosphériques (amplitude journalière et écart à la normale 1981-2010 des températures). En moyenne, les tn sont plus élevés …
