Hypes can be a significant contributor in the mainstreaming of sustainable products. Former research on hypes has been supplier oriented, and thus little is known of their effect on new market formation. Our paper contributes to this research gap by examining the establishment of the ‘meat substitute’ category in Finland using press articles, retailer interviews and consumer panel data. We show how the emergence and legitimation of the meat substitute category depended heavily on the hype arising around a single product, called Pulled Oats (PO). This hype was anchored in its association with trendy and socio-culturally relevant values and practices. We further discover that the hype had positive spill-over effects on other novel meat substitute products but not on longstanding vegetarian protein sources such as tofu or tempeh. We discuss the contribution of these findings to the literature on hypes and sustainability transitions, especially regarding socially constructed market boundaries and the fact that the hype on PO lacked a disappointment phase typical of hype cycles. peerReviewed

Introduction Body weight perception (BWP) is associated with health behaviors. Current evidence points to an increase over time in both actual and perceived weight status among adolescents, however there is limited evidence on time trends in BWP in cross-national samples of adolescents. Therefore, the aims of this study were to examine time trends in BWP between 2002 and 2018 among adolescents from 41 countries and regions, including gender and country differences and to explore the role of changes over time in country-level overweight/obesity prevalence in these trends. Methods Data were used from five cycles (2002, 2006, 2010, 2014, 2018) of the repeated cross-sectional Health Behavior in School-Aged Children (HBSC) study (n = 746,121; mean±standard deviation age 13.7 ± 1.6 years, 51.0% girls). Multilevel logistic models estimated cross-national linear time trends in adolescent BWP (correct perception, underestimation, or overestimation), adjusted for gender, age, and family affluence. Next, we tested whether country-level changes over time overweight/obesity prevalence could explain these trends in BWP among adolescents. Results Correct weight perception increased over time among girls, while it decreased among boys. Underestimation of weight status increased, and overestimation of weight status decreased over time among both genders, with stronger trends for girls. Furthermore, country differences in trends in both BWP and overweight/obesity were found. Changes over time in country-level overweight/obesity prevalence could not explain these trends. Conclusion The linear increase over time in correct weight perception and the decrease in overestimation may have a positive effect on unhealthy weight reduction behaviors among adolescents. However, the increase in underestimation could signal a need for interventions to strengthen correct weight perception among adolescents. Several implications for policy and practice are discussed. peerReviewed

Public relations (PR) focuses on storytelling by creating newsworthy content that will be communicated to target audiences. However, because social media has empowered individual consumers to an unprecedented level, we are no longer passive consumers of stories and some consumers have even reached influencer status where their opinions carry great authority. In the future, PR stories will shape global culture, but the Covid-19 pandemic has also alerted us to the damage caused by deliberate misinformation (e.g. the anti-vaccination movement). The digital environment — especially where PR now operates — is changing rapidly; artificial intelligence and machine learning are assisting corporations in processing vast volumes of unstructured data. Currently, trust in online communications is eroding in general, but the future of Web3 with blockchain technology may reverse this erosion by introducing new trust protocols into digital interactions. peerReviewed

It is important to track the trends of future working hours, since working hours have strong associations to everyday life and work-life interaction, but also to health. In this paper we aim to track the current and future trends in working hours. We discuss the trends through the key dimensions of working hours: the length, timing, tempo and autonomy. We also consider the role of current trends of spatial changes of work. Changes in working time patterns are fostered by several driving factors: globalization and business restructuring challenging the current work organizations, new information technologies, demographic and climate change and the current and future pandemics. The past and current tremendous changes in working hours indicate that changes in working hours will continue. The contemporary trends in future working hours pose risks for personal, family and social life, material well-being and health. At its best, however, the new post-industrial working time regime may provide more autonomy and time for recovery to employees as new technologies and changes in business structures release opportunities for greater individual autonomy over how, where, and for how long paid work is performed. peerReviewed

Purpose: The purpose of the study was to examine the trends between 2002 and 2018 in school pressure and school satisfaction among 15-year-old students, across countries and by gender, in the WHO European region and North America, and explore whether there are variations between countries and by gender in the co-occurrence of school pressure and school satisfaction. Methods: Data from the 32 countries that participated in the Health Behaviour in School-aged Children study (HBSC) study between 2002 and 2018 were used. Statistical analyses included ttests, binary logistic regression analyses, and chi-square tests, as required by each of the study aims. Results: School satisfaction tended to increase over the period 2002e2018 among boys, whereas school pressure increased among girls. Also, gender differences tended to dissipate in school satisfaction and generally increase in school pressure. The co-occurrence of school satisfaction and school pressure in 2017/2018 shows that the majority of students are found in the “not pressured enot highly satisfied” and “pressuredenot highly satisfied” groups. There were more boys in the former group and more girls in the latter group. Conclusion: Few students in the 32 countries belonged to the “not pressuredehighly satisfied” group, which from a public health perspective may be seen as the most desirable group. The increases in school pressure in girls from 2002 to 2018 and their overrepresentation in the pressured groups require further attention.

In recent decades, lakes have experienced unprecedented ice loss with widespread ramifications for winter ecological processes. The rapid loss of ice, resurgence of winter biology, and proliferation of remote sensing technologies, presents a unique opportunity to integrate disciplines to further understand the broad spatial and temporal patterns in ice loss and its consequences. Here, we summarize ice phenology records for 78 lakes in 12 countries across North America, Europe, and Asia to permit the inclusion and harmonization of in situ ice phenology observations in future interdisciplinary studies. These ice records represent some of the longest climate observations directly collected by people. We highlight the importance of applying the same definition of ice-on and ice-off within a lake across the time-series, regardless of how the ice is observed, to broaden our understanding of ice loss across vast spatial and temporal scales.

Global trends influence the approaches and mindset for using natural resources and technological capacities. Participatory scenario methods have proven useful in long-term foresight. However, country-level foresight studies often ignore the broader trends affecting international markets and setting frames for economic development. This study envisions which global trends could occur and how the resulting European policies might affect the Finnish forest sector’s development in 2040. We applied a Futures Wheel approach, where stakeholder groups consisting of policy-, economic- and social sustainability-, technology-, and climate sustainability -experts in the field of forestry and interlinking industries created three future scenarios in a workshop: (1) biodiversity and regulated economy, (2) circular economy, and (3) era of social connection. The scenarios assumed growing resource scarcity as a result of climate change, as well as over-consumption and increasing inequality problems globally. Thus, European-level policies focused on the circular economy and resource-use restrictions. Finnish industries should invest in wood-based side stream and waste utilization to increase added value and decrease virgin wood uses to succeed in these scenarios. However, this would require investments in non-wood energy sources to release these secondary wood flows from energy uses. peerReviewed

Este artículo contiene 17 páginas, 6 figuras, 2 tablas., Dissolved organic carbon (DOC) and nitrogen (DON) are important energy and nutrient sources for aquatic ecosystems. In many northern temperate, freshwater systems DOC has increased in the past 50 years. Less is known about how changes in DOC may vary across latitudes, and whether changes in DON track those of DOC. Here, we present long-term DOC and DON data from 74 streams distributed across seven sites in biomes ranging from the tropics to northern boreal forests with varying histories of atmospheric acid deposition. For each stream, we examined the temporal trends of DOC and DON concentrations and DOC:DON molar ratios. While some sites displayed consistent positive or negative trends in stream DOC and DON concentrations, changes in direction or magnitude were inconsistent at regional or local scales. DON trends did not always track those of DOC, though DOC:DON ratios increased over time for ~30% of streams. Our results indicate that the dissolved organic matter (DOM) pool is experiencing fundamental changes due to the recovery from atmospheric acid deposition. Changes in DOC:DON stoichiometry point to a shifting energynutrient balance in many aquatic ecosystems. Sustained changes in the character of DOM can have major implications for stream metabolism, biogeochemical processes, food webs, and drinking water quality (including disinfection by-products). Understanding regional and global variation in DOC and DON concentrations is important for developing realistic models and watershed management protocols to effectively target mitigation efforts aimed at bringing DOM flux and nutrient enrichment under control., National Institute of Food and Agriculture, Grant/Award Number: 1016163, 1019522 and 1022291; Natural Environment Research Council, Grant/Award Number: NE/K010689/1; NSF EPSCoR, Grant/ Award Number: EPS-1929148; Division of Environmental Biology, Grant/ Award Number: 1545288 and 1556603; European Regional Development Fund, Grant/Award Number: RTI2018-094521- B-100 and RYC-2017-22643

Contradictory results for the long-term evolution of nitrogen and phosphorus concentrations in waters discharging from drained peatland forests need reconciliation. We gathered long-term (10–29 years) water quality data from 29 forested catchments, 18 forestry-drained and 11 undrained peatlands. Trend analysis of the nitrogen and phosphorus concentration data indicated variable trends from clearly decreasing to considerably increasing temporal trends. While the variations in phosphorus concentration trends over time did not correlate with any of our explanatory factors, trends in nitrogen concentrations correlated positively with tree stand volume in the catchments and temperature sum. A positive correlation of increasing nitrogen concentrations with temperature sum raises concerns of the future evolution of nitrogen dynamics under a warming climate. Furthermore, the correlation with tree stand volume is troublesome due to the generally accepted policy to tackle the climate crisis by enhancing tree growth. However, future research is still needed to assess which are the actual processes related to stand volume and temperature sum that contribute to increasing TN concentrations.

Highlights • Novel techniques for presenting exceedances of critical loads (CL) and their temporal development were developed. • Concentrations and fluxes of N and S compounds in deposition and runoff have decreased as a response to decreasing emissions. • Most sites with higher CL exceedances showed larger decreases in both inorganic N and H+ concentrations and fluxes in runoff. • Effects of the cumulative exceedance of the eutrophication CL were evaluated. • The results provide evidence on the link between CL exceedances and empirical impacts. Anthropogenic emissions of nitrogen (N) and sulphur (S) compounds and their long-range transport have caused widespread negative impacts on different ecosystems. Critical loads (CLs) are deposition thresholds used to describe the sensitivity of ecosystems to atmospheric deposition. The CL methodology has been a key science-based tool for assessing the environmental consequences of air pollution. We computed CLs for eutrophication and acidification using a European long-term dataset of intensively studied forested ecosystem sites (n = 17) in northern and central Europe. The sites belong to the ICP IM and eLTER networks. The link between the site-specific calculations and time-series of CL exceedances and measured site data was evaluated using long-term measurements (1990–2017) for bulk deposition, throughfall and runoff water chemistry. Novel techniques for presenting exceedances of CLs and their temporal development were also developed. Concentrations and fluxes of sulphate, total inorganic nitrogen (TIN) and acidity in deposition substantially decreased at the sites. Decreases in S deposition resulted in statistically significant decreased concentrations and fluxes of sulphate in runoff and decreasing trends of TIN in runoff were more common than increasing trends. The temporal developments of the exceedance of the CLs indicated the more effective reductions of S deposition compared to N at the sites. There was a relation between calculated exceedance of the CLs and measured runoff water concentrations and fluxes, and most sites with higher CL exceedances showed larger decreases in both TIN and H+ concentrations and fluxes. Sites with higher cumulative exceedance of eutrophication CLs (averaged over 3 and 30 years) generally showed higher TIN concentrations in runoff. The results provided evidence on the link between CL exceedances and empirical impacts, increasing confidence in the methodology used for the European-scale CL calculations. The results also confirm that emission abatement actions are having their intended effects on CL exceedances and ecosystem impacts.

Achieving sustainable development as an inclusive societal process in rural landscapes, and sustainability in terms of functional green infrastructures for biodiversity conservation and ecosystem services, are wicked challenges. Competing claims from various sectors call for evidence-based adaptive collaborative governance. Leveraging such approaches requires maintenance of several forms of social interactions and capitals. Focusing on Pan-European regions with different environmental histories and cultures, we estimate the state and trends of two groups of factors underpinning rural landscape stewardship, namely, (1) traditional rural landscape and novel face-to-face as well as virtual fora for social interaction, and (2) bonding, bridging, and linking forms of social capital. We applied horizon scanning to 16 local landscapes located in 18 countries, representing Pan-European social-ecological and cultural gradients. The resulting narratives, and rapid appraisal knowledge, were used to estimate portfolios of different fora for social interactions and forms of social capital supporting landscape stewardship. The portfolios of fora for social interactions were linked to societal cultures across the European continent: "self-expression and secular-rational values" in the northwest, "Catholic" in the south, and "survival and traditional authority values" in the East. This was explained by the role of traditional secular and religious local meeting places. Virtual internet-based fora were most widespread. Bonding social capitals were the strongest across the case study landscapes, and linking social capitals were the weakest. This applied to all three groups of fora. Pan-European social-ecological contexts can be divided into distinct clusters with respect to the portfolios of different fora supporting landscape stewardship, which draw mostly on bonding and bridging forms of social capital. This emphasizes the need for regionally and culturally adapted approaches to landscape stewardship, which are underpinned by evidence-based knowledge about how to sustain green infrastructures based on both forest naturalness and cultural landscape values. Sharing knowledge from comparative studies can strengthen linking social capital.

Two streams of literature have become especially prominent in understanding social change toward sustainability within the past decades: the research on socio-technical transitions and applications of social practice theory. The aim of this article is to contribute to efforts to create dialogue between these two approaches. We do this by focusing on the concept of reconfiguration, which has become a much-used, but poorly defined notion in the discussion on sustainability transitions. To understand what is defined as reconfiguration in systems and practices, and how the understanding of reconfiguration in regimes could benefit from insights about reconfiguration in practices, we conducted a systematic and critical literature review of 43 journal articles. The findings showed a trend toward a focus on whole-system reconfiguration and interlinked dynamics between practices of production and consumption. However, our study suggests that a less hierarchical understanding of transitions utilizing insights from practice theory might be fruitful. Future research on sustainability transitions could benefit from addressing the tensions between and within niche and regime practices; the dynamics maintaining and challenging social and cultural norms; the efforts in creating new normalities and in recruiting actors in practices; and investigating the different roles the various actors play in these practices. peerReviewed

Tässä artikkelissa tutkitaan henkilöstöjohtamisen ajankohtaisia trendejä digitalisoituvassa toimintaympäristössä. Digitalisaatio on voimakkaasti yleistyvä ilmiö, jota voi tarkastella laaja-alaisesti henkilöstöjohtamisen kenttää muovaavana metatrendinä tai suppeammin joukkona ohjelmisto- ja tiedonhallintateknologioita, joilla pyritään tehostamaan organisaation toimintaa ja vähentämään kustannuksia. Tutkimusstrategia on laadullinen ja analyysissa olemme soveltaneet sisällön erittelyä aikaisemman kirjallisuuden ja empiirisen haastatteluaineiston yhdistävällä otteella. Empiirinen aineisto koostuu 17 suomalaisen henkilöstöammattilaisen temaattisesta sähköpostihaastattelusta. Löydöksemme jakautuu neljään osaan, joissa käsitellään henkilöstöjohtamisen ajankohtaisia ongelmia, organisaatioiden digitaalisia HR-järjestelmiä, tekoälyä ja henkilöstöjohtamista sekä henkilöstöjohtamisen trendejä. Keskeisiä vallitsevia ongelmia ovat esimerkiksi työehtosopimusneuvotteluiden vaikeudet, rutiinitöiden kuormittavuus, rekrytointi sekä johtamisen haasteet, kuten konfliktit organisaatioissa. Digitalisaatio on aineistossa vahvasti vallitseva niin sanottu megatrendi, joka määrittää selvästi henkilöstöjohtamisen tulevaisuuden suuntaa ja on yhtäaikaisesti sekä syy että mahdollinen ratkaisu moniin vallitseviin henkilöstöjohtamisen ongelmiin. Selkeitä aineistosta nousevia teknologisia HR-trendejä ovat tekoäly, automatisaatio, mobiili- ja pilvipalvelut sekä reaaliaikaista, prosessoitua informaatiota tuottavat järjestelmät. Digitalisaation ohella painotetaan myös ihmislähtöistä henkilöstöjohtamista. Siinä trendejä tämän tutkimuksen mukaan ovat erityisesti vuorovaikutteisuus, vastuullisuus, hyvinvointi sekä työn merkityksellisyys. Lisäksi etenkin rekrytoinnin tärkeys tulee esille. peerReviewed

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. Multivariate logistic regression analyses were used to assess WRB trends over time, adjusted for survey year, body mass index, body weight misperception, and family affluence and stratified by gender and age. Results In the 26 countries examined, the overall age-adjusted prevalence rates of WRB were 10.2% among boys and 18.0% among girls. The prevalence of WRB was higher for girls, but in the more recent surveys, gender differences in WRB decreased. There was a significant increase in the percentage of WRB among boys in most countries. Among girls, most countries did not experience significant changes. Increases in body mass index and overestimation of body weight were significant factors increasing the risk of WRB in both genders. Conclusions The change in the prevalence of WRB by gender warrants greater attention from researchers and practitioners alike. peerReviewed

In recent years, the Norwegian government has invested heavily in improving basic skills in the adult population. Initiatives have included legislation, the introduction of work-based adult education programs, and reforms in schooling. In light of this investment, we explore trends in adult literacy and numeracy, by comparing data from two international surveys of adult skills, conducted in 2003 and 2012. Paradoxically, the proportion of low-performing adults appears to have increased, most significantly in the 16- to 24-year age group and in the foreign-born population. The profile of the lowest performing group has changed in the intervening years. These findings suggest that adult education programs and the education system more generally may not be in concord with the goal of including all in the communities of the literate. We discuss policy implications, in the context of the Scandinavian model, but argue that the discussion is applicable beyond national boundaries.

Sleep has been found to be an important factor in adolescents’ mental and physical health. The aim of the present study was to examine trends in sleep difficulty (i.e., difficulty falling asleep more often than once a week) in the Nordic countries among 11- to 15-year-olds. We analysed Nordic data from the Health Behaviour in School-aged Children study (HBSC), which is conducted every four years, looking specifically at trends in sleep difficulty over a 12-year period from 2002 to 2014. The participants were aged 11 to 15 years. The total number of participants across these years was 113,447. A large percentage (17% to 31% in 2014) of adolescents in the Nordic countries experience sleep difficulty, and these difficulties increased from 2002 to 2014 in Denmark, Finland, Iceland, and Sweden. Only in Norway was there a decrease, mainly due to a reduction in sleep difficulty among 11-year-old boys and girls from 2010 to 2014. Sleep difficulty among boys and girls are prevalent and generally on the rise in the Nordic countries with the exception of Norway.

Short summary The surface albedo time series CLARA-A2 SAL was used to study trends in the timing of the melting season of snow and preceding albedo value in Finland during 1982–2016 to assess climate change. The results were in line with operational snow depth data, JSBACH land ecosystem model, SYKE fractional snow cover and greening-up data. In the north a clear trend to earlier snowmelt onset, increasing melting season length, and decrease in pre-melt albedo (related to increased stem volume) was observed. The surface albedo time series, CLARA-A2 SAL, was used to study trends in the snowmelt start and end dates, the melting season length and the albedo value preceding the melt onset in Finland during 1982–2016. In addition, the melt onset from the JSBACH land surface model was compared with the timing of green-up estimated from Moderate Resolution Imaging Spectroradiometer (MODIS) data. Moreover, the melt onset was compared with the timing of the greening up based on MODIS data. Similarly, the end of snowmelt timing predicted by JSBACH was compared with the melt-off dates based on the Finnish Meteorological Institute (FMI) operational in situ measurements and the Fractional Snow Cover (FSC) time-series product provided by the EU FP7 CryoLand project. It was found that the snowmelt date estimated using the 20 % threshold of the albedo range during the melting period corresponded well to the melt estimate of the permanent snow layer. The longest period, during which the ground is continuously half or more covered by snow, defines the permanent snow layer (Solantie et al., 1996). The greening up followed within 5–13 days the date when the albedo reached the 1 % threshold of the albedo dynamic range during the melting period. The time difference between greening up and complete snowmelt was smaller in mountainous areas than in coastal areas. In two northern vegetation map areas (Northern Karelia–Kainuu and Southwestern Lapland), a clear trend towards earlier snowmelt onset (5–6 days per decade) and increasing melting season length (6–7 days per decade) was observed. In the forested part of northern Finland, a clear decreasing trend in albedo (2 %–3 % per decade in absolute albedo percentage) before the start of the melt onset was observed. The decreasing albedo trend was found to be due to the increased stem volume.

BACKGROUND: To analyse the psychometric properties of the HBSC Symptom Checklist (HBSC-SCL) on psychosomatic symptoms with a focus on the operating characteristics of the items, and on the impacts of measurement distortions on the comparisons of person measures across time and between countries.METHODS: Data were collected in 1993/94, 1997/98, 2001/02, 2005/06, 2008/09, 2013/14 in Denmark, Finland, Norway and Sweden as part of the Health Behaviour in School-aged Children (HBSC) study. Data comprised 116,531 students 11, 13 and 15 years old. Rasch analysis was conducted of the HBSC-SCL consisting of eight items with a focus on Differential Item Functioning (DIF) and item threshold ordering. The impacts of DIF and threshold disordering on trend analyses were analysed in a subsample consisting of 15 years old students.RESULTS: One item shows evidence of severe DIF and the categorisation of some items does not seem to work as intended. Analyses of changes based on proportions of psychosomatic symptoms show that bad item functioning affects some comparisons between countries across time: A four percentage point difference between 15 years old girls in Finland and Sweden concerning the rate of increase of psychosomatic symptoms from 1994 to 2014 disappears when the problems with DIF and disordered item thresholds are taken into account. Although the proportions of students with psychosomatic symptoms are clearly higher 2014 than 1994 in all four countries the shape of most trends is nonlinear.CONCLUSIONS: Some of the cross-country comparisons were distorted because of DIF and problems related to disordering of the item thresholds. The comparisons among girls between Finland and Sweden were affected by the problems pertaining to the original measure of psychosomatic symptoms, while the trend patterns among boys were not much affected. In addition to confirming increasing rates of adolescent mental health problems in the Nordic countries, the substantive analyses in the current study show that Finland is joining Sweden in having the sharpest increase among older adolescents, in particular among girls. To improve the functioning of the scale the DIF item could be removed or replaced and response categories collapsed in post hoc analyses.

Background: Excellent self-rated health (SRH) can be seen as an important component of positive health among adolescents. The aim of this paper is to examine time trends of excellent health among adolescents in five Nordic countries (Denmark, Finland, Iceland, Norway and Sweden) between 2002 and 2014, including differences between countries, gender and age. Methods: Nordic data from the Health Behaviour in School-aged Children (HBSC) survey (including 11-, 13- and 15-year-olds) from 2002 (n = 19,009), 2006 (n = 29,656), 2010 (n = 33,232) and 2014 (n = 31,540) were analysed by design-adjusted binomial logistic regression models. Results: The trend analysis of excellent SRH for Nordic adolescents indicates a small improvement between 2002 and 2006 but a stable trend in the following periods up until 2014. The time trends do, however, depend on the specific country. In general, a smaller proportion of girls compared to boys were found to rate their health as excellent. Over time, however, the proportion of boys rating their health as excellent decreased, while girls’ ratings improved. Conclusions: From a public health perspective, indications of a changing trend in adolescent health coinciding with the 2007–2008 global recession warrant further attention from researchers and policy-makers and should be closely monitored in the future.

A long-term trophic development of three geographical transects—including a river mouth, an estuary, and an archipelago—were studied in the southern Finnish coast in the Baltic Sea. Each transect was studied to clarify how far off the coast the land-based nutrient sources (catchment factor, CF) had a decisive role in shaping the wintertime regimes of dissolved inorganic nitrogen and dissolved inorganic phosphorus and where the marine processes (marine factor, MF) start to play a major role. Generally, CF controlled the nutrient regime from the coast to the outer brink of the inner coastal area, after which MF started to dominate. The estuaries exhibited steep vertical nutrient gradients, above which the riverine input dominated the nutrient regime. The extent of the area where CF dominated the nutrient regime was therefore decisively dependent on estuarine stratification, i.e., whether the conclusions were drawn based on the surface layer data, including the riverine impact, or on the data beneath that layer, including the marine impact. This result deviates from the current consensus that the trophic regime of the sea is most directly assessed by the surface layer nutrient content. The estuarine nutrient regime is unrepresentative to that of a typical coastal water body due to the strong land-based impact on the estuary. Therefore, any generalization of the trophic condition of an estuary to represent areas farther off the coast should be done cautiously. The estuaries should also be defined as belonging to transitional waters according to the typology related to European Marine Legislation.

Reasons for participating in physical activity (PA) may have changed in accordance with the general modernization of society. The aim is to examine changes in self-reported reasons for liking leisure-time physical activity (LTPA) and their association with self-reported LTPA over a 20-year period. Data were collected among nationally representative samples of 13-year-olds in Finland, Norway, and Wales in 1986 and 2006 (N = 9252) as part of the WHO cross-national Health Behaviour in School-aged Children (HBSC) study. Univariate ANOVAs to establish differences according to gender, year, and country were conducted. In all countries, 13-year-olds in 2006 tended to report higher importance in terms of achievement and social reasons than their counterparts in 1986, while changes in health reasons were minor. These reasons were associated with LTPA in a similar way at both time points. Health reasons for liking LTPA were considered most important, and were the strongest predictor of LTPA. The findings seem robust as they were consistent across countries and genders. Health education constitutes the most viable strategy for promoting adolescents' motivation for PA, and interventions and educational efforts could be improved by an increased focus on LTPA and sport as a social activity. publishedVersion

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 the relationships between alcohol use, drunkenness and indicators of socioeconomic status. Results: The study showed that the alcohol use and drunkenness of Finnish 15-year-old adolescents have decreased since the late 1990s. However, the level of decrease is not consistent among different socioeconomic groups and socioeconomic differences in drinking behaviour between two educational aspiration groups have persisted over two decades. Girls from the groups with low perceived family wealth were more likely to be frequently drunk in the time period 2006–2014. Conclusions: This study suggests that students with low educational aspiration should be the target population for interventions aiming at reducing the alcohol use and drunkenness of Finnish adolescents. In future interventions aimed at reducing heavier drinking, adolescents (especially girls) from less wealthy families should be the first priority. Further studies on trends in socioeconomic differences in alcohol use and drunkenness in adolescence should be conducted using different indicators of socioeconomic status and other social context factors should also be taken into account.

Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease. We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and number of people with, raised blood pressure, defined as systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher. Methods For this analysis, we pooled national, subnational, or community population-based studies that had measured blood pressure in adults aged 18 years and older. We used a Bayesian hierarchical model to estimate trends from 1975 to 2015 in mean systolic and mean diastolic blood pressure, and the prevalence of raised blood pressure for 200 countries. We calculated the contributions of changes in prevalence versus population growth and ageing to the increase in the number of adults with raised blood pressure. Findings We pooled 1479 studies that had measured the blood pressures of 19·1 million adults. Global age-standardised mean systolic blood pressure in 2015 was 127·0 mm Hg (95% credible interval 125·7–128·3) in men and 122·3 mm Hg (121·0–123·6) in women; age-standardised mean diastolic blood pressure was 78·7 mm Hg (77·9–79·5) for men and 76·7 mm Hg (75·9–77·6) for women. Global age-standardised prevalence of raised blood pressure was 24·1% (21·4–27·1) in men and 20·1% (17·8–22·5) in women in 2015. Mean systolic and mean diastolic blood pressure decreased substantially from 1975 to 2015 in high-income western and Asia Pacific countries, moving these countries from having some of the highest worldwide blood pressure in 1975 to the lowest in 2015. Mean blood pressure also decreased in women in central and eastern Europe, Latin America and the Caribbean, and, more recently, central Asia, Middle East, and north Africa, but the estimated trends in these super-regions had larger uncertainty than in high-income super-regions. By contrast, mean blood pressure might have increased in east and southeast Asia, south Asia, Oceania, and sub-Saharan Africa. In 2015, central and eastern Europe, sub-Saharan Africa, and south Asia had the highest blood pressure levels. Prevalence of raised blood pressure decreased in high-income and some middle-income countries; it remained unchanged elsewhere. The number of adults with raised blood pressure increased from 594 million in 1975 to 1·13 billion in 2015, with the increase largely in low-income and middle-income countries. The global increase in the number of adults with raised blood pressure is a net effect of increase due to population growth and ageing, and decrease due to declining age-specific prevalence. Interpretation During the past four decades, the highest worldwide blood pressure levels have shifted from high-income countries to low-income countries in south Asia and sub-Saharan Africa due to opposite trends, while blood pressure has been persistently high in central and eastern Europe.

This study investigates methodological trends in mobile communication studies. The articles published over the past 20 years in five journals (Communication Research, Journal of Communication, Journal of Computer-Mediated Communication, New Media & Society, and Information, Communication & Society) are analysed. The results show that the quantitative and qualitative studies have increased while theoretical accounts have remained few. The quantitative approach is the most applied. The studied articles reflect a structural problem of science communication that stems from the lack of cumulativity of scientific results and cross-national analyses and from the standard length of articles that poses limitations for scientific communication. peerReviewed

[Introduction] International comparative higher education research has proliferated since its institutionalization as an interdisciplinary field in the 1960s and 1970s (Jarausch 1985) and has gained special momentum in the 1990s (Teichler 1996). On the one hand, the benefits of comparative research approaches in international higher education have been repeatedly emphasized (Altbach and Kelly 1985; Teichler 1996; Rhoades 2001). These include, for example, increasing the capacity to generalize about a greater number of units under analysis, the capacity of a systematic comparison to illuminate the dynamics of a particular system better than a single-system study as well as highlighting knowledge gaps. On the other hand, methodological debates about comparing higher education internationally and how best to compare them emerged hand-in-hand with the field’s growth in popularity. Although the logic of international comparative research does not differ from research undertaken just within one country (Teichler 1996; Goedebuure and Van Vught 1996), some problems are posed in an especially complicated and intractable fashion (Hantrais 2009; Smelser 1976/2013), because of the focus on units that are dissimilar as well as similar (to be comparable). This poses specific challenges to international comparative research. [Continues, please see the article] nonPeerReviewed

Background One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the agestandardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with diabetes. Methods We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence—defi ned as fasting plasma glucose of 7·0 mmol/L or higher, or history of diagnosis with diabetes, or use of insulin or oral hypoglycaemic drugs—in 200 countries and territories in 21 regions, by sex and from 1980 to 2014. We also calculated the posterior probability of meeting the global diabetes target if post-2000 trends continue. Findings We used data from 751 studies including 4 372 000 adults from 146 of the 200 countries we make estimates for. Global age-standardised diabetes prevalence increased from 4·3% (95% credible interval 2·4–7·0) in 1980 to 9·0% (7·2–11·1) in 2014 in men, and from 5·0% (2·9–7·9) to 7·9% (6·4–9·7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28·5% due to the rise in prevalence, 39·7% due to population growth and ageing, and 31·8% due to interaction of these two factors). Age-standardised adult diabetes prevalence in 2014 was lowest in northwestern Europe, and highest in Polynesia and Micronesia, at nearly 25%, followed by Melanesia and the Middle East and north Africa. Between 1980 and 2014 there was little change in age-standardised diabetes prevalence in adult women in continental western Europe, although crude prevalence rose because of ageing of the population. By contrast, age-standardised adult prevalence rose by 15 percentage points in men and women in Polynesia and Micronesia. In 2014, American Samoa had the highest national prevalence of diabetes (>30% in both sexes), with age-standardised adult prevalence also higher than 25% in some other islands in Polynesia and Micronesia. If post-2000 trends continue, the probability of meeting the global target of halting the rise in the prevalence of diabetes by 2025 at the 2010 level worldwide is lower than 1% for men and is 1% for women. Only nine countries for men and 29 countries for women, mostly in western Europe, have a 50% or higher probability of meeting the global target. Interpretation Since 1980, age-standardised diabetes prevalence in adults has increased, or at best remained unchanged, in every country. Together with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. peerReviewed

WHO:s skolelevsstudie (Health Behavior in School-aged Children (HBSC) Study) är internationellt en av de mest omfattande, långvariga och betydelsefulla undersökningarna om levnadsvanor bland skolungdomar. Undersökningen startade för drygt 30 år sedan och i detta nu deltar över 40 länder i Europa och Nordamerika. Nästa internationella datainsamling, som är den tionde i ordningen, genomförs år 2018. Nytt forskningsmaterial insamlas vart fjärde år. Forskare vid Jyväskylä universitets Forskningscenter för hälsofrämjande (Terveyden edistämisen tutkimuskeskus) ansvarar för WHO:s skolelevsstudie i Finland. För ungefär 20 år sedan började det givande samarbetet mellan Jyväskylä universitet och Samfundet Folkhälsan. Åren 1994, 1998, 2006 och 2014 har skilda datainsamlingar gjorts bland elever i svenskspråkiga skolor. WHO:s skolelevsstudie är till sitt forskningsgrepp en trendundersökning. Ju längre tidsperspektiv resultaten representerar, desto viktigare och intressantare blir en trendundersökning. Föreliggande rapport är den första i sitt slag att beskriva trender i upplevd hälsa, hälsobeteenden och skolupplevelser under de senaste 20 åren bland 11-, 13- och 15-åriga elever i svenskspråkiga skolor i Finland. Trendjämförelser med motsvarande resultat bland elever i finskspråkiga skolor har heller inte gjorts tidigare. Tidsperspektivet är imponerande, och resultaten är ytterst intressanta och viktiga då man överväger strategier och metoder att förbättra hälsa och välbefinnande bland ungdomar i skolåldern. Rapporten är speciellt viktig för det hälsofrämjandet arbetet i Svenskfinland – det är första gången man så här omfattande har kartlagt hälsa bland finlandssvenska ungdomar och gjort både en jämförelse mellan finlandssvenskar i olika regioner och samtidigt en jämförelse till finskspråkiga barn och ungdomar. Att färdigställa föreliggande rapport var möjligt genom att datainsamlingen i svenskspråkiga skolor kunde genomföras med hjälp av beviljade medel ur Anslaget för hälsofrämjande (Institutet för hälsa och välfärd, THL) och medel ur Utbildningsstyrelsens anslag, samt genom att Svenska kulturfonden beviljade understöd för bearbetning och analys av datamaterialet och skrivande av rapporten. Vårt varma tack för finansieringen. Analyser och rapportering har planerats och förverkligats av forskargrupper vid Folkhälsans forskningscentrum och Jyväskylä universitet. Vi vill tacka båda forskargrupperna, liksom Carola Ray och Åse Fagerlund som läst och kommenterat texten. Undersökningen kunde inte ha genomförts utan skolornas insatser, och vi vill rikta ett stort tack till alla deltagande skolor, rektorer och lärare. Ett särskilt varmt tack går till alla elever som så omsorgsfullt har besvarat frågeformulären.

Article, Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5–22.7) and 16.5 cm (13.3–19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8–144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries., published version, http://purl.org/eprint/status/PeerReviewed

This study compiles a new dataset, consisting of the longest available flow series from across Europe, and uses it to study the spatial and temporal clustering of flood events across the continent. Hydrological series at 102 gauging stations were collected from 25 European countries. Five geographically distinct large-scale homogeneous regions are identified: (i) an Atlantic region, (ii) a Continental region, (iii) a Scandinavian region, (iv) an Alpine region, and (v) a Mediterranean region. The months with a higher likelihood of flooding were identified in each region. The analysis of the clustering of annual counts of floods revealed an over-dispersion in the Atlantic and Continental regions, forming flood-rich and flood-poor periods, as well as an under-dispersion in the Scandinavian region that points to a regular pattern of flood occurrences at the inter-annual scale. The detection of trends in flood series is attempted by basing it on the identified regions, interpreting the results at a regional scale and for various time periods: 1900-1999; 1920-1999; 1939-1998 and 1956-1995. The results indicate that a decreasing trend in the magnitude of floods was observed mainly in the Continental region in the period 1920-1999 with 22% of the catchments revealing such a trend, as well as a decreasing trend in the timing of floods in the Alpine region in the period 1900-1999 with 75% of the catchments revealing this trend. A mixed pattern of changes in the frequency of floods over a threshold and few significant changes in the timing of floods were detected. (C) 2015 Elsevier B.V. All rights reserved.

Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across many different regions around the world. However, the spatial and temporal coherence associated with the magnitude of these trends remains unclear. Thus, a global data set of water temperature is required to understand and synthesize global, long-term trends in surface water temperatures of inland bodies of water. We assembled a database of summer lake surface temperatures for 291 lakes collected in situ and/or by satellites for the period 1985–2009. In addition, corresponding climatic drivers (air temperatures, solar radiation, and cloud cover) and geomorphometric characteristics (latitude, longitude, elevation, lake surface area, maximum depth, mean depth, and volume) that influence lake surface temperatures were compiled for each lake. This unique dataset offers an invaluable baseline perspective on global-scale lake thermal conditions as environmental change continues.

Tulevaisuudentutkimuksen yhtenä pyrkimyksenä on vaikuttaa tulevaisuutta koskevan tiedon avulla nykyhetken ratkaisuihin. Onko sitten aina selvää, kumman aikaulottuvuuden mentaalista ongelmakenttää tiedon hankinnassa painotetaan? Tässä artikkelissa tarkastellaan tulevaisuudentutkimuksessa suositun skenaariomenetelmän kertomuksellisuuden suhdetta tutkimuksen uskottavuusvaatimukseen ja sen kulloinkin sisältämään totuusrakenteeseen. Konkreettisena lähtökohtana tarkastelussa on vuosina 2006–2007 laadittu kartoitus suomalaisen metsäalan vaihtoehtoisista kehitysmalleista globalisaatiossa.

Tässä työssä on tutkittu Suomen ympäristökeskuksen valtakunnallisia virtaama- ja vedenkorkeusaikasarjoja vuoteen 2004 saakka. Tarkastelun kohteena on 25 virtaamasarjaa ja lisäksi vedenkorkeuksia 13 havaintopaikalta eri puolilta maata. Mukana on sekä luonnontilaisia että säännösteltyjä jokia ja järviä. Lisäksi tutkimuksessa on tarkasteltu koko Suomen alueelta lähtevää virtaamaa vuodesta 1912 alkaen. Pisimmät työssä analysoidut havaintosarjat alkavat jo 1800-luvun puolivälistä, mutta useimmat 1910- tai 1930-luvulta. Julkaisu esittelee kattavasti Suomen vesistöjen vedenkorkeuksien ja virtaamien kulun piirteitä sekä pitkäaikaismuutoksia. Työssä on esitetty tietoja Suomen vedenkorkeus- ja virtaamaoloista tekstien lisäksi taulukoiden ja useiden eri kuvaajien avulla. Tilastojen ja aikasarjojen ohella työssä esitellään havaintomenetelmiä ja tarkastellaan erilaisten tekijöiden (mm. ilmastolliset sekä ihmisen toiminnasta aiheutuvat) vaikutuksia virtaamaoloihin. Trendianalyysin pohjalta on nähtävissä, että luonnontilaisilla havaintopaikoilla erityisesti talven ja kevään keskivirtaamat sekä alivirtaamat ovat kasvaneet tilastollisesti merkitsevästi. Säännösteltyjen havaintopaikkojen osalta virtaamaolot ovat muuttuneet varsin merkittävästi, erityisesti talvivirtaamat ovat kasvaneet, mutta kesävirtaamat ja alivirtaamat pienentyneet. Kevätvirtaamahuipun aikaistumista on havaittavissa kolmasosalla kaikista työssä tarkastelluista havaintopaikoista. Vuoden keskivirtaamassa tai ylivirtaamassa muutoksia ei ollut yleisesti havaittavissa luonnontilaisilla eikä säännöstellyillä havaintopaikoilla. Selvä talvi- ja kevätkeskivirtaamien kasvu suurimmalla osalla havaintopaikoista kertoo talvien ja keväiden lämpenemisestä sekä keväiden aikaistumisesta, mikä on havaittavissa myös ilmastollisista aikasarjoista.

Tämän tutkimuksen tarkoituksena oli osoittaa eläkeikäisten suomalaisten toimintakyvyn ja terveyskäyttäytymisen muutoksia ja yhteyksiä väestötasolla vuosien 1985-2003 välillä. Lisäksi tutkittiin toimintakyvyn ja terveyskäyttäytymisen sosiodemografisia eroja. Aineistona käytettiin kahden vuoden välein toteutettua Eläkeikäisen väestön terveyskäyttäytymistutkimusta (EVTK), jota on kerätty vuodesta 1985 lähtien. Tutkimukseen valittujen 65-79-vuotiaiden naisten ja miesten kokonaismäärä oli 13 232 vuosien 1985-2003 välillä. Keskimääräinen vastausprosentti oli hieman yli 80. Itse ilmoitettuja päivittäistoimintoja (ADL) käytettiin kuvaamaan toimintakykyä. Terveyskäyttäytymistä tutkittiin ruokavalion, tupakoinnin, alkoholinkäytön, fyysisen aktiivisuuden ja myös painoindeksin kautta. Toimintakyvyn ja terveyskäyttäytymisen yhteyksien tarkastelussa vakioitiin myös kroonisten sairauksien vaikutus. Sosiodemografisia eroja tarkasteltiin ikäryhmien, eläkeikää edeltävän ammatin ja siviilisäädyn kautta. Tulokset raportoitiin ikävakioitujen trendien sekä logistisen että ordinaalisen regression avulla. Tutkimus osoitti toimintakyvyn kohentuneen 1980-luvun puolestavälistä vuosituhannen vaihteeseen. Toimintakyky oli parempi nuoremmilla vastaajilla, toimistotyötä tehneillä ja naimissa olevilla. Tämän päivän eläkeikäiset syövät terveellisemmin ja tupakoivat vähemmän, mutta käyttävät enemmän alkoholia ja ovat lihavampia kuin ikätoverinsa pari vuosikymmentä sitten. Terveellisen ruokavalion noudattaminen, tupakointi, alkoholinkäyttö ja lihavuus olivat yleisimpiä nuorimassa ikäryhmässä. Maataloustyötä tehneiden keskuudessa oli vähiten terveellistä ruokavaliota noudattavia ja eniten lihavia. Alkoholinkäyttö oli puolestaan yleisempää toimistotyötä tehneillä. Naimissa olevat noudattivat useammin terveellistä ruokavaliota ja tupakoivat vähemmän kuin ei-naimisissa olevat. Terveellinen ruokavalio, tupakointi, alkoholin käyttämättömyys ja runsas käyttö, fyysinen passiivisuus ja lihavuus olivat yhteydessä huonompaan toimintakykyyn. Näiden tekijöiden sekä kroonisten sairauksien havaittiin vähentävän toimintakyvyn sosiodemografisia eroja tämä vika lause ei ehkä aukene kaikille. Toimintakyvyn ja terveyskäyttäytymisen koheneminen tarkoittaa terveempiä elinvuosia tulevaisuuden eläkeikäisille. Tästä positiivisesta kehityksestä huolimatta väestöryhmittäiset erot ovat edelleen selkeät. Nämä erot yhdessä lisääntyvän lihavuuden ja alkoholinkäytön kanssa ovat haasteita kansanterveydelle .

Changes in water quality in Finnish lakes and rivers 1962-1977

Pohjoismaat ovat perinteisesti erottuneet työelämän laatuvertailuissa Euroopan ykkösinä. Taustalla vaikuttavat työmarkkinoiden palveluvaltaisuus ja korkea työvoiman osaamistaso, mutta myös erilaiset institutionaaliset tekijät, kuten työmarkkinoiden sääntely, ammattiyhdistysliikkeen asema ja sosiaalipoliittiset ratkaisut. Työelämän laatu voi kuitenkin heikentyä, kun näitä ankkureita kierretään tai kun ne eivät tavoita kaikkien alojen työntekijöitä. Organisaatioiden uudelleenjärjestelyt, ulkoistaminen ja alihankinta sekä uusien alojen ja työnteon uusien muotojen syntyminen saattavat heikentää työelämän laatua. nonPeerReviewed
