Weight Reduction Behaviors Among European Adolescents : Changes From 2001/2002 to 2017/2018
2020
Purpose The purpose of this study was to analyze changes in the prevalence of weight reduction behaviors (WRBs) among European adolescents from 26 countries between 2001/2002 and 2017/2018. The impact of the perception of body weight on WLB was also analyzed, with particular attention being paid to overestimation. Methods The data of 639,194 European adolescents aged 11, 13, and 15 years who participated in the Health Behaviour in School-aged Children survey were analyzed. Age-standardized prevalence rates of WRB were estimated separately by survey round and gender for each country, using the overall 2017/2018 Health Behaviour in School-aged Children study population as the standard. Multiv…
Socioeconomic differences in the use of alcohol and drunkenness in adolescents: Trends in the Health Behaviour in School-aged Children study in Finla…
2018
Aims: The aims of this study were to explore time-based trends of socioeconomic differences in alcohol use and drunkenness in Finnish adolescents from 1990 to 2014 and to investigate the significance of two indicators in detecting socioeconomic differences in alcohol use and drunkenness. Methods: Data were retrieved from seven surveys conducted as part of the Health Behaviour in School-aged Children (HBSC) study in Finland from 1990 to 2014. The alcohol use and drunkenness of 15-year-old students, as well as socioeconomic status, including educational aspiration and perceived family wealth, were assessed via a self-report questionnaire. Logistic regression models were used to investigate t…
Conservation status of the Italian flora under the 92/43/EEC ‘Habitats’ Directive
2021
The results of the 4th National Report for the Italian flora under the 92/43/EEC ‘Habitats’ Directive are presented. The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.
Kan mobile applikasjoner bidra til livsstilsendring? : en kvalitativ studie av treningsapplikasjonen Styrk!
2016
Masteroppgave i helse- og sosialinformatikk- Universitetet i Agder, 2016 Smartphones and mobile applications has gradually become an integrated part of everyday life for many people. There are applications for most areas of life, and an increasing amount of new apps are related to health and fitness. At the same time the developed countries of the world, including Norway, struggles within activity and the health problems that comes with it. It is a fact that most non-communicable diseases are related to inactivity, and increasing the level of physical activity among the population is important for prevention of these diseases. For those already affected by a noncomunicable disease a change …
Situational factors shape moral judgements in the trolley dilemma in Eastern, Southern and Western countries in a culturally diverse sample
2022
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of …
Benthic foodweb structure in a large shallow lake studied by stable isotope analysis
2014
The benthic foodweb structure of Lake Võrtsjärv, a large (270 km2), shallow, and turbid Estonian lake, was evaluated based on C and N stable-isotope signatures (δ13C, δ15N). Variation in δ13C between sampling sites was not related to site proximity to the littoral zone or the more vegetated southern part of the lake, but rather appeared to be influenced by in-situ site peculiarities. δ13C was stable temporally and between functional feeding groups, a result implying that the whole benthic food web of the lake relies largely on the same C source admixture, essentially particulate organic matter (POM). Thus, the foodweb composition of Lake Võrtsjärv is remarkably homogeneous given the lake’s …
Tracking mite trophic interactions by multiplex PCR
2020
Background A thorough knowledge of trophic webs in agroecosystems is essential to achieve successful biological pest control. Phytoseiid mites are the most efficient natural enemies of tetranychid mites, which include several important pests worldwide. Nevertheless, phytoseiids may feed on other food sources including other microarthropods, plants and even other phytoseiids (intraguild predation), which can interfere with biological control services. Molecular gut content analysis is a valuable tool for characterizing trophic interactions, mainly when working on microarthropods such as mites. We have designed new primers for Phytoseiidae, Tetranychidae and Thysanoptera identification and th…
The identity of the tropical African Polichne mukonja Griffini, 1908 (Orthoptera, Tettigoniidae, Phaneropterinae)
2016
Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both taxa are p…
The legacy of human use in Amazonian palm communities along environmental and accessibility gradients
2023
Aim: Palms are iconic and dominant elements of neotropical forests. In the Amazon region, palms have been used and managed by humans for food, material, medicine and other purposes for millennia. It is, however, debated to what extent the structure of modern palm communities reflects long-term human modification. Here, we investigate the complex interplay of ecological and societal factors that influence the distributions of both human-used and non-used palms in western Amazonia. Location: Amazonia. Time period: Present. Major taxa studied: Palms (Arecaceae). Methods: We used Bayesian hierarchical joint species distribution models to predict the distributions and environmental niche dimensi…
