Kokemuksia haastavista ja kuormittavista tilanteista varhaiskasvattajien työssä

Opinnäytetyön lisäosan tarkoituksena oli selvittää, millaisia haastavia ja kuormittavia tilanteita varhaiskasvattajat voivat kohdata työssään lasten, huoltajien, työyhteisön ja muiden tilanteiden parissa. Tutkimustehtävä keskittyi erityisesti siihen, millä tavalla haasteisiin voidaan vaikuttaa ja millaisiin tilanteisiin varhaiskasvattajat kokevat itse pystyvänsä vaikuttamaan ja millaisiin eivät. Tutkielmassa käsiteltiin myös varhaiskasvattajien kokemia työn voimavaroja, jotka osaltaan tukevat varhaiskasvattajien työssä jaksamista. Tutkielmassa vertailtiin varhaiskasvattajien ja muskariopettajien kokemuksien samankaltaisuuksia, koska tämä tutkielma täydensi aikaisempaa musiikkipedagogin (AMK) opinnäytetyötäni (Mäkipelto 2014). Teoreettinen viitekehys muodostui tässä tutkielmassa työhyvinvointiin liittyvästä kirjallisuudesta ja aikaisemmasta tutkimuksesta, joissa tarkasteltiin työkäytäntöjen ja työn voimavara- ja kuormitustekijöiden vaikutuksia työhyvinvointiin. Tutkielma toteutettiin kvalitatiivisena eli laadullisena tutkimuksena ja tutkimusmenetelmänä käytettiin puolistrukturoitua teemahaastattelua. Teemahaastattelu analysoitiin teemoittelun ja aineistolähtöisen sisällönanalyysin avulla. Yhteistyökumppanina oli Norlandia päiväkodit. Haastatteluun osallistui neljä varhaiskasvattajaa, joiden kokemukset eivät liittyneet ainoastaan nykyiseen työpaikkaan Norlandian päiväkodissa, vaan ne koskivat myös aikaisempaa työhistoriaa. Tutkimustulokset osoittivat, että haastavat ja kuormittavat kokemukset liittyivät erityisesti lapsiryhmän hallintaan, huoltajien kohtaamiseen, työyhteisön ristiriitoihin, työn ulkopuoliseen elämään ja työnkuvaan liittymättömiin tilanteisiin kuten siivoamiseen. Ongelmanratkaisukeinoiksi nimettiin lasten parissa tunteiden käsittely ja rauhallinen vuorovaikutus. Varhaiskasvattajat kokivat, että huoltajien parissa auttoi kunnioittava suhtautuminen ja säännöllinen tiedottaminen. Työyhteisössä korostui yhteisten sääntöjen, kommunikoinnin ja toimivan johtajuuden merkitys. Muissa tilanteissa painotettiin työn ulkopuolisesta elämästä huolehtimista. Varhaiskasvattajat kokivat, että lasten perheoloihin ja resurssien puutteeseen he eivät pystyneet vaikuttamaan. Työn voimavaroina painottui lasten riemu ja kehitys, toimiva yhteistyö huoltajien ja työyhteisön parissa sekä oman työn kehittäminen, arvostaminen ja rajaaminen. Edeltävissä tuloksissa oli paljon yhteneväisyyksiä aikaisempien tutkimustulosten kanssa. Varhaiskasvattajat ja muskariopettajat olivat kokeneet yhtäläisiä haastavia tilanteita erityisesti lapsiryhmän hallintaan, huoltajien kohtaamiseen ja työyhteisössä heikkoon perehdytykseen ja sääntöjen epäselvyyteen liittyvissä tilanteissa. Ongelmanratkaisukeinoina korostui molemmissa ammattiryhmissä lasten parissa keskusteleminen, yhteisten sääntöjen, periaatteiden ja toimintatapojen vahvistaminen. Varhaiskasvattajat ja muskariopettajat kokivat lasten riemun ja työkavereiden tuen voimavaraksi. Johtopäätöksistä ilmeni, että varhaiskasvattajien ja muskariopettajien työssä korostui vuorovaikutuksen merkitys. Mikäli vuorovaikutus oli heikkoa, se aiheutti enemmän kuormitusta. Jos vuorovaikutus toimi, yhteisöllisyys lisääntyi ja toimi voimavarana. Jatkossa voitaisiin tutkia enemmän erityisesti työn ulkopuolisen elämän yhteyttä varhaiskasvattajien hyvinvointiin ja moniammatillisten varhaiskasvattajien erilaisia kokemuksia. Niiden merkitys korostui tässä tutkielmassa ja aikaisemmissa tutkimuksissa.The purpose of the supplementary thesis was to find out what kind of challenging and stressful situations early childhood educators may face in their work with children, guardians, the work community and other situations. The aim was to find ways to influence the challenges and find out which situations early childhood educators feel themselves capable of influencing and which not. The thesis focused also on the strengthening factors experienced by early childhood educators, which contribute to the well-being of early childhood educators. Moreover, the thesis compares similarities between the experiences of early childhood educators and music playschool teachers as this thesis complements my earlier bachelor’s thesis in early childhood music education (Mäkipelto 2014). The theoretical framework of this thesis consists of occupational well-being literature and earlier studies, which examined the effects of work practices and work strength and stress factors on occupational well-being. The thesis was carried out as qualitative research and a semi-structured thematic interview was used as the research method. The thematic interview was analyzed with theme and content analysis. The cooperation partner was Norlandia Päiväkodit. Four early childhood educators participated in the interview. Their experiences were not only related to the current job at the Norlandia kindergarten, but also on past work history. The results demonstrated that challenging and stressful experiences were especially related to group management with children, the interaction with guardians, conflicts in the work community, life outside the workplace, and work assignment issues not included in the job description such as cleaning. Problem solving included emotional management and peaceful interaction with children. Early childhood educators felt that respect and regular information helped with guardians. In the work community the importance of common rules, communication and effective leadership were emphasized. The life outside of work was emphasized in other situations. Early childhood educators felt that they were unable to influence children's family conditions and lack of resources. The work strength-factors consisted of the joy and development of children, effective cooperation with guardians and the work community, as well as the development, appreciation and delimitation of their own work. These results had several similarities with previous research results. Early childhood educators and music playschool teachers had experienced similar challenging situations, especially in the group management with children, the interactions with guardians, and in the work community in situations involving weak orientation and unclear rules. Both professional groups solved problems by discussing with children and enforcing common rules and principles. Both professional groups felt that the joy of children and support from colleagues strengthened their work resources. The study concluded that interaction is important for both early childhood educators and music playschool teachers. If interaction was weak, it caused more stress. If it worked, communality increased and it served as a strength factor. The occupational wellbeing of early childhood educators could be studied further by focusing on life-factors outside work and a multi-professional perspective. The importance of these perspectives was emphasized in this thesis and former studies

100 years of water supply and sanitation in Finland This book is written by Petri S. Juuti, Tapio S.Katko & Riikka P. Rajala. Finland is known as a land of thousands of lakes. Yet, there are regions in Finland where lakes are very few and the lack of fresh water is an ordinary problem. Finland is quite unique in Fennoscandia as to its water resources. The country has some 56 000 lakes with a minimum area of one hectare and all together 200000 lakes. Ground water occurs in alluvial eskers formed during ice ages, the last of which ended some 10 000 years ago. Nowadays some 60 per cent of the people use natural or artificially recharged ground water. However, areas lower than 50–60 metres above sea level have problems with water quality due to geological reasons. In such areas bigger cities use surface water for their water supply or acquire their raw water from sources further away. The book shows us how water supply and sanitation have developed in Finland during years of political independence starting from the year 1917.Tässä dosentti Petri Juutin, dosentti Tapio Katkon ja TkT Riikka Rajalan kirjoittamassa vertaisarvioidussa monografiassa on kuvattu koko Suomen vesihuollon eli vedenhankinnan ja jätevesihuollon historia sadan vuoden ajalta.

History of water and health from ancient civilizations to modern times

Abstract This paper examines the influence of water on public health throughout history. Farming, settling down and building of villages and towns meant the start of the problems mankind suffers from this very day -how to get drinkable water for humans and cattle and how to manage the waste we produce. The availability of water in large quantities has been considered an essential part of a civilized way of life in different periods: Roman baths needed a lot of water as does the current Western way of life with water closets and showers. The importance of good quality drinking water was realized already in antiquity, yet the importance of proper sanitation was not understood until the 19th century

Optimization of process models for determining volatility distribution and viscosity of organic aerosols from isothermal particle evaporation data

The composition of organic aerosol under different ambient conditions as well as their phase state have been a subject of intense study in recent years. One way to study particle properties is to measure the particle size shrinkage in a diluted environment at isothermal conditions. From these measurements it is possible to separate the fraction of low-volatility compounds from high-volatility compounds. In this work, we analyse and evaluate a method for obtaining particle composition and viscosity from measurements using process models coupled with input optimization algorithms. Two optimization methods, the Monte Carlo genetic algorithm and Bayesian inference, are used together with process models describing the dynamics of particle evaporation. The process model optimization scheme in inferring particle composition in a volatility-basis-set sense and composition-dependent particle viscosity is tested with artificially generated data sets and real experimental data. Optimizing model input so that the output matches these data yields a good match for the estimated quantities. Both optimization methods give equally good results when they are used to estimate particle composition to artificially test data. The timescale of the experiments and the initial particle size are found to be important in defining the range of values that can be identified for the properties from the optimization

Growth rates of nucleation mode particles in Hyytiälä during 2003−2009: variation with particle size, season, data analysis method and ambient conditions

The condensational growth rate of aerosol particles formed in atmospheric new particle formation events is one of the most important factors influencing the lifetime of these particles and their ability to become climatically relevant. Diameter growth rates (GR) of nucleation mode particles were studied based on almost 7 yr of data measured during the years 2003–2009 at a boreal forest measurement station SMEAR II in Hyytiälä, Finland. The particle growth rates were estimated using particle size distributions measured with a Differential Mobility Particle Sizer (DMPS), a Balanced Scanning Mobility Analyzer (BSMA) and an Air Ion Spectrometer (AIS). Two GR analysis methods were tested. The particle growth rates were also compared to an extensive set of ambient meteorological parameters and trace gas concentrations to investigate the processes/constituents limiting the aerosol growth. The median growth rates of particles in the nucleation mode size ranges with diameters of 1.5–3 nm, 3–7 nm and 7–20 nm were 1.9 nm h⁻¹, 3.8 nm h⁻¹, and 4.3 nm h⁻¹, respectively. The median relative uncertainties in the growth rates due to the size distribution instrumentation in these size ranges were 25%, 19%, and 8%, respectively. For the smallest particles (1.5–3 nm) the AIS data yielded on average higher growth rate values than the BSMA data, and higher growth rates were obtained from positively charged size distributions as compared with negatively charged particles. For particles larger than 3 nm in diameter no such systematic differences were found. For these particles the uncertainty in the growth rate related to the analysis method, with relative uncertainty of 16%, was similar to that related to the instruments. The growth rates of 7–20 nm particles showed positive correlation with monoterpene concentrations and their oxidation rate by ozone. The oxidation rate by OH did not show a connection with GR. Our results indicate that the growth of nucleation mode particles in Hyytiälä is mainly limited by the concentrations of organic precursors

Characteristics of new particle formation events and cluster ions at K-puszta, Hungary

Atmospheric new particle formation events were analyzed based on particle size distributions measured with a Differential Mobility Particle Sizer (DMPS) and an Air Ion Spectrometer (AIS) during the BIOSOL (Formation mechanisms, marker compounds, and source apportionment for biogenic atmospheric aerosols) campaign on 22 May-29 June 2006 at the K-puszta measurement site in Hungary. The particle size distribution data were classified into different new particle event classes and growth and formation rates of the particles were calculated. New particle formation was observed on almost all days and the median diameter growth rates of nucleation mode particles increased with increasing particle size. The observed formation rate of 10 nm particles was typically somewhat larger than 1 cm(-3) s(-3) (median 1.2), and the growth rate for sub 3 nm particles was 1.7 nm h(-1) and for nucleation mode 6 nm h(-1). The ambient concentrations of gases or meteorological data were not able to explain the differences in the growth and formation rates or in the particle formation between the days. However, 0.3-1.8 nm cluster ion concentrations correlated negatively with wind speed

Ambient observations of dimers from terpene oxidation in the gas phase : Implications for new particle formation and growth

We present ambient observations of dimeric monoterpene oxidation products (C16-20HyO6-9) in gas and particle phases in the boreal forest in Finland in spring 2013 and 2014, detected with a chemical ionization mass spectrometer with a filter inlet for gases and aerosols employing acetate and iodide as reagent ions. These are among the first online dual-phase observations of such dimers in the atmosphere. Estimated saturation concentrations of 10(-15) to 10(-6)mu gm(-3) (based on observed thermal desorptions and group-contribution methods) and measured gas-phase concentrations of 10(-3) to 10(-2)mu gm(-3) (similar to 10(6)-10(7)moleculescm(-3)) corroborate a gas-phase formation mechanism. Regular new particle formation (NPF) events allowed insights into the potential role dimers may play for atmospheric NPF and growth. The observationally constrained Model for Acid-Base chemistry in NAnoparticle Growth indicates a contribution of similar to 5% to early stage particle growth from the similar to 60 gaseous dimer compounds. Plain Language Summary Atmospheric aerosol particles influence climate and air quality. We present new insights into how emissions of volatile organic compounds from trees are transformed in the atmosphere to contribute to the formation and growth of aerosol particles. We detected for the first time over a forest, a group of organic molecules, known to grow particles, in the gas phase at levels far higher than expected. Previous measurements had only measured them in the particles. This finding provides guidance on how models of aerosol formation and growth should describe their appearance and fate in the atmosphere.Peer reviewe
