    Objective of the study Work stress affects teachers mental and physical well-being, increases costs and sick leave, and affects work productivity. Prolonged, intense stress is associated with lower job satisfaction. The decline of teachers´ well-being also has a negative effect on students' learning. Recovery from work is important for health, ability to work and the teacher's own well-being. In today's working life, the time left for recovery has decreased and the individual must take more and more care of his or her own well-being and recovery. Successful recovery effectively prevents work demands from developing into stressors. The aim of this study was to find out which elements of work polytechnic teachers find stressful in their work, what effects they perceive as work stress, what means of recovery they have at their disposal and what things may prevent success of recovery. Methods The 22 interviews were analysed using qualitative content analysis, in which they report on their own well-being, stress experiences and recovery from work as part of a broader thematic interview. The interview material has been collected since the end of 2019. Results and conclusions Polytechnic teachers perceive excessive workload, uneven workload and hurry as the most stressful elements in their own work. An examination of the effects of stress experiences showed that teachers perceive that work stress affects them above all mentally. Of the physical effects, sleep-related problems in particular were reflected in teachers' coping. An examination of the means of recovery showed that polytechnic teachers consider hobbies and social relationships to be the most important means of recovery. Most polytechnic teachers experience challenges in recovering from work. The majority of teachers feel that recovery is not enough or is only seasonal. Haste and too much work proved to be the biggest obstacles to recovery not always succeeding.

    Current practices in wastewater management lead to inefficient recovery and reuse of nutrients and can result in environmental problems. Source separation systems have been shown to be an efficient way of recovering nutrients and energy from wastewaters, both in rural and urban context. Studies on nutrient recovery potential and life cycle impacts of source separation systems are mainly limited to small systems (for example a few households) while the impacts of upscaling source separation to a regional level have hardly been studied, especially in sparsely populated areas where the cost of the connection to a main treatment plant is higher. This study examines the regional nutrient balance of two source separation scenarios—black water separation and urine diversion—and compares them to the existing conventional wastewater system. The analysis comprises three sparsely populated regions of northern Finland and Sweden, including rural, peri-urban and urban areas. In addition, climate impacts are assessed based on existing life cycle assessment (LCA) studies. According to the results, by source separation it is possible to achieve a significant increase in the recovery rate of phosphorus (41–81%) and nitrogen (689–864%) compared to the conventional system. Depending on the region up to 65% of the mineral phosphorus and 60% of mineral nitrogen fertilisers could be theoretically replaced. Furthermore, the climate and eutrophication impacts would decrease with the implementation of such systems, but an increase in acidification may occur. However, even if the benefits of source separation systems are undisputed in terms of nutrient recovery, the implementation of such systems would to a large extent require an entire system change of the wastewater treatment sector and a wide paradigm change towards a circular economy.

    Environmental Evidence 8, 39 (2019)
    Background Agriculture is the main sector responsible for nutrient emissions in the Baltic Sea Region and there is a growing pressure to identify cost-effective solutions towards reducing nitrogen and phosphorus loads originating from farming activities. Recycling resources from agricultural waste is central to the idea of a circular economy, and has the potential to address the most urgent problems related to nutrients use in the food chain, such as depletion of natural phosphorus reserves, water pollution and waste management. This systematic map examined what evidence exists relating to the effectiveness of ecotechnologies in agriculture for the recovery and reuse of carbon and/or nutrients (nitrogen and phosphorus) in the Baltic Sea region and other comparable boreo-temperate systems. Methods We searched for both academic and grey literature. English language searches were performed in 5 bibliographic databases and search platforms, and Google Scholar. Searches in 36 specialist websites were performed in English, Finnish, Polish and Swedish. The searches were restricted to the period 2013 to 2017. Eligibility screening was conducted at two levels: title and abstract (screened concurrently for efficiency) and full text. Meta-data was extracted from eligible studies including bibliographic details, study location, ecotechnology name and description, type of outcome (i.e. recovered or reused carbon and/or nutrients), type of ecotechnology in terms of recovery source, and type of reuse (in terms of the end-product). Findings are presented here narratively and in a searchable database, and are also visualised in a web-based evidence atlas (an interactive geographical information system). In addition, knowledge gaps and clusters have been identified in the evidence base and described in detail. Results We found 173 articles studying the effectiveness of 177 ecotechnologies. The majority of eligible articles were in English, originated from bibliographic databases and were published in 2016. Most studies with reported locations, and given our boreo-temperate scope, were conducted in Europe and North America. The three most prevalent ecotechnologies in the evidence base (collectively 40.7%) were; soil amendments, anaerobic digestion and (vermi)composting. Manure was the principal waste source used for recovery of nutrients or carbon, making up 55.4% of the all studies in evidence base, followed by a combination of manure and crop residues (22%). There were 51 studies with 14 ecotechnologies that reported on recovery of carbon and nutrients together, predominantly via (vermi)composting and anaerobic digestion. Only 27 studies focused on reuse of recovered nutrients and carbon through soil amendments. Conclusions This systematic map report provides an evidence base that can be useful for researchers and decision-makers in policy and practice working on transformation from linear to circular economy in the agricultural waste sector. Three potential topics for future systematic reviews are: (1) effectiveness of products recovered from different types of agricultural wastes as soil amendments or fertilizers; (2) effectiveness of anaerobic digestion as an ecotechnology used for recovery of nutrients and carbon; (3) effectiveness of composting and/or vermicomposting as ecotechnologies used for recovery of nutrients and carbon.
  • Kinos-Järvinen, Anne (Helsingin yliopisto, 2019)
    The research task of this Master's thesis is to describe, analyze and interpret how the principals of Finnish elementary schools and high schools experience their workload and their job satisfaction. These are examined by the workload and resource factors of principal’s job. In addition, the ways of how the workload appears and ways of recovery are discussed. The thesis is a qualitative pilot study for a broader welfare research conducted by the Finnish Principals Association, which will be implemented during 2019. Previous studies on the work of a Finnish principal have shown that his job description is extensive, that the workload is high and job satisfaction is put to the test every day. This research was guided by the following research questions: How do principals experience their workload and work satisfaction? What are the factors that the principals feel stressing them on their work and how does the workload show? What do the principals feel are resource factors in their work and how and by what means do they recover? The material consists of interviews with sixteen Finnish principals of elementary schools and high schools. The interviews were conducted as a semi-structured theme interview. The interview questions related to the principal’s own experience of their job satisfaction, workload, the ways in which the workload appears, their experience of the resources of their work, and how they feel they success to recover, and how do they recover. The material was analyzed phenomenographically because the subject of the research were the subjective perceptions and experiences of the principals. According to the material, the Finnish principals are very satisfied with their work, despite its relatively high workload. The experience of satisfaction arises especially through the independence, significance and influence of the work. The principal's experience and attitude also seemed to be relevant to how the workload was experienced. Generally, the workload was described high and the load was described to appear as typical stress-induced warning signs, but the principals, however, judged the workload as being reasonable. The workload was considered to be a natural part of the principal's work and the respondents tended to have a constructive attitude towards it. The principals also reported that their own recovery was generally successful, which according to respondents was of great importance to coping with work.
  • Hurmeranta, Emmi (Helsingin yliopisto, 2020)
    The aim of this article-type master's thesis was to examine the stress, coping, and metacognitive perspectives of special education teachers working in primary school during the remote teaching and learning period caused by the COVID-19 pandemic. The aim of the study was to examine what kind of stress and coping experiences the teachers had during the remote learning period, as well as what kind of mindset the teachers had when facing the workload. In addition, the dissertation examined the connection between teachers' ways of thinking and experiencing the intensity of workload. Experiences were examined using the Coping-Competence-Context (3C)-model. The data of the study was collected by thematic interviews with special education teachers (n = 11) working in different parts of Finland. Teachers were working in primary schools during the remote teaching and learning period. In these interviews conducted remotely, respondents were asked to describe their experiences of workload, recovery from work, and mindset and attitudes towards work. The data were analyzed using theoretical content analysis. Qualitative analysis program ATLAS.ti version 8 was used to organize the data. The workload experienced by special education teachers was mainly emotional, and often related to daily work changes. The coping strategies were used in a variety of ways, and their use was increased and new means were introduced during the remote learning period. The part of the 3C model focusing on recovery received support from teachers’ experiences, suggesting that teacher workload and recovery are directly related. The link between metacognitive perspectives and intensity of the workload was only partially supported: two teachers who had a stress-is-debilitating mindset experienced a higher-than-average workload. Instead, nine teachers who had a stress-is-enhancing mindset experienced both light and intense workload. The article ”Laaja-alaisten erityisopettajien työn kuormitus ja palautuminen sekä ajattelutavat COVID-19-pandemian aiheuttaman etäopetusjakson aikana: kokemusten tarkastelua Coping-Competence-Context-mallin avulla” is to be published in the NMI Bulletin.
  • Muilu, Kaisa (Helsingin yliopisto, 2019)
    Aims. It is important to study factors to manage work-related stress to get more tools to support sustainable ways of doing work and flourishing work environments. The purpose of this study was to examine what extent servant leadership, sense of community and workaholism are associated with burnout and recovery from work. Job Demands-Resources Model (Bakker & Demerouti, 2007) and Conservation of Resources Theory (Hobfoll, 2001) were used as a theoretical framework of the study. In this study servant leadership and sense of community were considered as resources and workaholism as a work-related demand. Previous studies have shown that servant leadership and sense of community are negatively associated with burnout, whereas no previous research exist focusing on the associations between servant leadership, sense of community and recovery. According to previous studies, workaholism is positively associated with burnout and negatively associated with recovery. In this study, following the JD-R model, it was hypothesized that servant leadership and sense of community are negatively associated with burnout and positively associated with recovery. In addition, it was also hypothesized that workaholism is associated positively with burnout and negatively with recovery. Methods. This study is a part of an occupational health study, in which three large organizations (N = 1415) were examined by using an e-mail questionnaire. The participants answered questions concerning burnout, recovery, servant leadership, community and workaholism. The data was analyzed using hierarchical regression analysis. Results and conclusions. The results showed that servant leadership and sense of community were negatively associated with burnout and positively associated with recovery. Workaholism was positively associated with burnout and negatively with recovery. As a conclusion, servant leadership and sense of community can serve as important social resources against burnout and support recovery from work. Thus, promoting servant leadership and employees’ sense of community might serve as advantages for organizations. In addition, it would be important to actively recognize workaholism to reduce its threat for employees’ well-being.

    The aim of this study was to examine the validity of a new measurement instrument called Recovery Profile, which was developed by Psycon Ltd. Recent changes in work life have brought psychological recovery to the debate. Research has shown that personality is associated with stress, burnout, and work engagement. The hypotheses of this study were that optimism, internal locus of control, and conscientiousness foster recovery from work whereas neuroticism, cautiousness, and pedantry hinder recovery. A need to lead as well as a need for achievement were associated with either as fostering or hindering characteristics depending on the work context. Recovery Profile was compared with the established Need for Recovery Scale (NFRS). The research data of NFRS were collected from Psycon personnel assessment clients (N=194) by using an online survey during the spring of 2022. NFRS results were combined with the results of the personality inventories that the respondents had filled in during their personnel assessment. The data analysis was conducted by using explorative factor analysis, correlations, and linear regression analysis. The results suggest a two-dimensional construct of the need for recovery: experience of a heavy workload and lack of social energy. Personality seems only to predict the lack of social energy dimension. The results show that personality predicts recovery from work although the proportions of variance explained are low. As regards the personality traits measured by Recovery Profile, this study indicates that high optimism, a need for achievement, and internal locus of control are associated with a low need for recovery, whereas high neuroticism and cautiousness are associated with a high need for recovery. Individual differences, work context as well as the impact of society should be considered when studying recovery. The consultant can help the client to find the most effective ways to recover from work by using Recovery Profile as an assisting tool in coaching sessions. In addition to the individual level, Recovery Profile is a prominent tool in the field of leadership development.

    The present work provides a regional-scale assessment of the changes in acidifying deposition in Finland over the past 30 years and the current pattern in the recovery of acid-sensitive lakes from acidification in relation to changes in sulphate deposition. This information is needed for documenting the ecosystem benefits of costly emission reduction policies and further actions in air pollution policy. The development of sulphate deposition in Finland reflects that of European SO2 emissions. Before the 1990s, reductions in sulphur emissions in Europe had been relatively small and sulphate deposition showed no consistent trends. Due to emission reduction measures that were then taken, sulphate deposition started to clearly decline from the late 1980s. The bulk deposition of sulphate has declined 40-60% in most parts of the country during 1990-2003. The decline in sulphate deposition exceeded the decline of base cation deposition, which resulted in a decrease in acidity and acidifying potential of deposition over the 1990s. Nitrogen deposition also decreased since the late 1980s, but less than that of sulphate, and levelling off during the 1990s. Sulphate concentrations in all types of lakes throughout Finland have declined from the early 1990s. The relative decrease in lake sulphate concentrations (average 40-50%) during 1990-2003 was rather similar to the decline in sulphate deposition, indicating a direct response to the reduction in deposition. There are presently no indications of elevated nitrate concentrations in forested headwater lakes. Base cation concentrations are still declining in many lakes, especially in south Finland, but to a lesser extent than sulphate allowing buffering capacity (alkalinity) to increase. The recovery has been strongest in lakes in which sulphate has been the major acidifying agent, and recovery has been the strongest and most consistent in lakes in south Finland. The recovery of lakes in central Finland and north Finland is not as widespread and strong as observed in south. Many catchments, particularly in central Finland, have a high proportion of peatlands and therefore high TOC concentrations, and runoff-induced surges of organic acids have been an important confounding factor suppressing the recovery of pH and alkalinity in these lakes. Chemical recovery is progressing even in the most acidified lakes, but the buffering capacity of many lakes is still low and still sensitive to acidic input. Chemical recovery is resulting in biological recovery with populations of acid-sensitive fish species increasing. Increasing TOC concentrations are indicated in small forest lakes in Finland, which appear to be related to decreasing sulphate deposition and improved acid-base status of the soil. A new challenge is climate change with potential trends in temperature, precipitation and runoff, which are expected to affect future chemical and biological recovery from acidification. The potential impact of mobilization and leaching of organic acids may become particularly important in Finnish conditions. Long-term environmental monitoring has evidently shown the success of international emission abatement strategies. The importance and value of integrated monitoring approach including physical, chemical and biological variables is clearly indicated, and continuous environmental monitoring is needed as a scientific basis for further actions in air pollution policy. The effect of climate change will increase data requirements, and should be taken into account when assessing long-term surface water quality and developing future monitoring networks, due to more complex processes involved.

    In Helsinki Medical school, half of the students experience lot of stress during their studies. Earlier inter-national research shows that university students wellbeing can be improved with practicing mindfulness skills, but in Finland there are fewer studies in this topic. Research on mindfulness trainings effects on different study programs, age-groups and genders are also missing. The aim of this study was to find out, if practicing mindfulness is linked to better wellbeing in university students in Helsinki Medical school. Other aim was to find out and there some effect concerning study program, gender, age, the amount of mindfulness training or earlier mindfulness background. The study was randomized controlled trial research with intervention- (N=52) and control group (N=35). Intervention group practiced mindfulness skills on different methods and control group had sup-port as usual from the university. The measures were gathered with online questionnaire in the in the baseline and at the end of the study (5-8weeks). T-test was used to analyze changes between baseline and finish measurements. Repeated ANOVA was used to measure intervention effect. The overall wellbeing in the intervention group did not change during the intervention. Whereas in control groups wellbeing decreased statistically significantly in almost every variable. It is possible, that mindfulness training helps to prevent increase of stress levels. There was seen decrease in subjective wellbeing in both groups, but in the intervention group the decrease was significantly less (p= 0.03, η2 =.053). The intervention effect size (η2) was small. In intervention group there was a significant differ-ence between medical and dentistry students and psychology and logopedics student’s subjective wellbe-ing (p=0.037, η2=.084). There was a moderate intervention effect (η2). Medical and dentistry students experienced more effect from the intervention. Due to small amount of the study subjects, results are di-rectional. The results support the earlier findings where mindfulness has effect on wellbeing. Methods based on mindfulness training should be studied more to find out cost effective and preventive ways to support medical student’s wellbeing. More research is also needed to find out the best methods for different genders, age groups and students from different study programs.

    Tavoitteet. Työhyvinvointiin vaikuttavat nykyajan muuttuvassa työelämässä useat eri tekijät, jotka voidaan karkeasti jakaa työn kuormitus- ja voimavaratekijöihin. Kohtuullinen määrä kuormitusta tekee työstä motivoivaa, mutta liiallinen kuormitus ja vähäiset voimavaratekijät voivat altistaa liialliselle stressille ja mahdolliselle loppuunpalamiselle. Työssä jaksaminen ja työn kuormituksista palautuminen vaikuttavat työntekijöiden kokonaisvaltaiseen hyvinvointiin sekä työn laatuun tasapainottamalla kuormitus- ja voimavaratekijöiden suhdetta. Puheterapeuttien työhyvinvointia on aiemmin tutkittu jonkin verran julkisella sektorilla työskentelevien puheterapeuttien näkökulmasta. Yksityisellä sektorilla työskentelevien puheterapeuttien työnkuva poikkeaa monin tavoin julkisella sektorilla työskentelevien puheterapeuttien työnkuvasta, mutta heidän työhyvinvoinnistaan ei ole aikaisemmin tehty tutkimusta. Tämän tutkimuksen tarkoituksena oli selvittää, miten yksityisellä sektorilla työskentelevät puhetera-peutit jaksavat työssään ja miten he palautuvat työn kuormituksista. Lisäksi selvitettiin millaisia keinoja puheterapeutit käyttävät edistääkseen työssä jaksamista ja palautuakseen työn kuormituksista. Menetelmät. Tutkimusta varten haastateltiin kahdeksaa yksityisellä sektorilla työskentelevää puheterapeuttia. Haastateltujen työpaikan laatu ja työkokemuksen määrä vaihtelivat. Haastattelumenetelmänä käytettiin puolistrukturoitua teemahaastattelua. Haastattelurunko muodostettiin aikaisempaan tutkimukseen ja aiheeseen keskeisesti liittyviin teorioihin pohjautuen. Haastattelut äänitettiin ja litteroitiin. Kerätty aineisto analysoitiin induktiivisen sisällönanalyysin keinoin. Tulokset ja johtopäätökset. Puheterapeuttien työssä jaksaminen oli tämän tuktimuksen havaintojen valossa hyvää. Puheterapeutit kokivat työssä jaksamisensa parantuneen työuransa aikana. Tärkeimpinä työssä jaksamista edesauttavina tekijöinä pidettiin kollegiaalista tukea, työn vapautta, asiakkaita, työnohjausta ja koulutuksia. Myös työn kuormituksista palautuminen oli tämän tutkimuksen tulosten mukaan hyvää. Palautumisen kannalta merkittävimpiä tekijöitä olivat uni, liikunta ja luonto, perhe ja sosiaaliset suhteet sekä harrastukset. Työssä jaksamista tukevat ja palautumista edesauttavat tekijät ovat yksilöllisiä, mutta yhdistäviä piirteitä löytyy paljon. Jatkossa olisi tarpeellista selvittää, millaisia kuormitustekijöitä yksityisellä sektorilla työskentelevien puheterapeuttien työnkuvaan sisältyy ja miten työorganisaatiossa voitaisiin tukea puheterapeuttien työhyvinvointia.
