Environmental citizenship in geography and beyond
2020
The need for wider action against environmental problems such as climate change has brought the debate about the role of citizen to the political, practical, and scientific domains. Environmental citizenship provides a useful tool to conceptualize the relation between citizenship and the environment. However, there exists considerable variation in the ways environmental citizenship is understood regarding both the aspect of citizenship and the relationship to the environment. In this article, we review the literature on environmental citizenship and investigate the evolution of the concept. The article is based on a literature search with an emphasis on geographical research. The concept of…
Framing sustainable lifestyles : organic consumption in a women's magazine
2017
Forms of sustainable lifestyles and more responsible ways to consume have become more popular in recent years. This is reflected also in that mainstream media discusses about sustainability. Similarly, there is a growing interest on organic produce, the organic market has grown steadily from the turn of the century. Due to the growing popularity of sustainability, the way media communicates about the issue, is of interest. This thesis studied how women’s magazines communicate about sustainable lifestyles, and sustainability in general. Especially, how the use of organic goods is reasoned and presented in a magazine is studied. The aim of the thesis was to uncover the frames, which the magaz…
Plasma polyunsaturated fatty acids are directly associated with cognition in overweight children but not in normal weight children
2016
Aim Polyunsaturated fatty acids are essential nutrients for the normal development of the brain. We investigated the associations between plasma polyunsaturated fatty acids and cognition in normal weight and overweight children. Methods The study recruited 386 normal weight children and 58 overweight children aged six to eight years and blood samples were drawn after a 12-hour fast. We assessed plasma polyunsaturated fatty acids using gas chromatography, cognition using Raven's Coloured Progressive Matrices, and overweight and obesity using the age-specific and sex-specific cut-offs from the International Obesity Task Force. The data were analysed by linear regression analyses adjusted for …
Do Loneliness and Social Isolation Predict Mortality Because of Hazardous Drinking?
2021
Introduction: Subjective feelings of loneliness and objective social isolation have been consistently connected with ill-health and mortality, though little work has empirically examined the mechanisms explaining the adverse effects. This study examines whether alcohol consumption explains the connection of loneliness and social isolation on mortality in different age and gender groups. Methods: The sample comprised a representative 1994 Finnish sample (n = 8,650) matched with 22-year follow-up mortality data. A multigroup path analysis with discrete survival time analyses was conducted. Results: There were unique differences in the associations between loneliness, social isolation, alcoho…
Internal heat gain from different light sources in the building lighting systems
2017
EU directives and the Construction Law have for some time required investors to report the energy consumption of buildings, and this has indeed caused low energy consumption buildings to proliferate. Of particular interest, internal heat gains from installed lighting affect the final energy consumption for heating of both public and residential buildings. This article presents the results of analyses of the electricity consumption and the luminous flux and the heat flux emitted by different types of light sources used in buildings. Incandescent light, halogen, compact fluorescent bulbs, and LED bulbs from various manufacturers were individually placed in a closed and isolated chamber, and t…
An Approach to Delineate Groundwater Bodies at Risk: Seawater Intrusion in Liepāja (Latvia)
2018
Groundwater quality in coastal areas is frequently affected by seawater intrusion as a consequence of intensive water consumption. To achieve “good chemical status” of a groundwater body according to Water Framework Directive the effects of saline or other intrusions should not be observed. Groundwater pumping in former decades has caused a significant seawater intrusion into confined aquifer in Liepāja and has led to deterioration of relatively wide coastal area of the third largest city in Latvia. However, the area affected by seawater intrusion is a small part of groundwater body F1 which overall chemical status is good. Thus, no specific management measures have been applied to explore …
Verification of IRRILAB Software Application for the Hydraulic Design of a Micro-Irrigation System by Using IRRIPRO for an Apple Farm in Sicily
2021
In recent years, many studies have been performed to develop simple and accurate methods to design micro-irrigation systems. However, most of these studies are based on numerical solutions that require a high number of iterations and attempts, without ensuring to maximize water use efficiency and energy-saving. Recently, the IRRILAB software, which is based on an analytical approach to optimally design rectangular micro-irrigation units, has been developed, providing the solution corresponding to the maximum energy-saving condition, for any slope of the laterals and of the manifold. One IRRILAB limitation is that, according to its theoretical basis, the rectangular planform geometry and uni…
Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
Fast and accurate methodology for direct mercury determination in hair and nails
2015
AbstractA solvent-free, easy, fast and waste-free methodology was developed for the determination of total mercury levels in hair and nails. Samples were taken from several volunteers and directly analysed, with levels of mercury in the range between 0.5 and 8 ng/mg. The influence of quantity of hair, as well as the addition of small amount of solvent and the necessity of previous treatment were studied. Also, a history of mercury exposure was provided by the distance of the hair from the scalp of each volunteer, the results of which were correlated with fish consumption. Furthermore, a short study of mercury in nails was carried out and correlated to the results from hair mercury levels. A…
A survey on lifestyle and attitudes on fruit and vegetable consumption and participation in physical activity in a sample of secondary school and uni…
2010
<p><strong>Background</strong>: Fruit and vegetable (F&amp;V) consumption, and physical activity (PA), are thought to be some of the most important protective factors that can improve long-term health quality of life. Many epidemiological studies indicate, in fact, that F&amp;V consumption and PA are health-promoting and are correlated with the beneficial effects and positive outcomes such as preventing some chronic diseases. Evidence, however, indicates that large proportions of adolescents are not consuming the minimum servings of F&amp;V as recommended by experts and a high percentage of them have sedentary habits.</p><p><strong>Objective a…
