Tehokkuuserot tekonivel- ja polvileikkauksissa : tuloksia StoNED-menetelmän sovelluksesta
Tämän tutkimuksen tavoite oli selvittää, voidaanko DEA- ja SFA-menetelmien ominaisuuksia yhdistävää Stochastic non-smooth envelopment of data (StoNED)- menetelmää käyttää terveydenhuollon tehokkuusanalyysiin. Tämän selvittämiseksi luotiin katsaus lonkan, polven ja nilkan tekonivelleikkausten sekä lyhythoitoisten polvileikkausten tuotannon kustannustehokkuuteen Manner-Suomen sairaanhoitopiireissä vuonna 2010. Lisäksi tutkimuksessa tarkasteltiin kyseisten leikkausten tuotantomäärissä ja tuotantoon liittyvissä laskennallisissa kustannuksissa tapahtuneita muutoksia aikavälillä 2006-2010. Kustannustehokkuuden tutkimiseksi tuotettiin StoNED-menetelmän empiirinen sovellus, jossa panosmuuttujana kä…
Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) differ in their suitability as hosts for the endangered freshwater pearl mussel (Margaritifera margaritifera) in northern Fennoscandian rivers
European populations of the freshwater pearl mussel (FPM, Margaritifera margaritifera) have collapsed across much of the species’ geographic range and, despite many types of conservation intervention, the number of successful restoration efforts has been low. The goal of this study was to determine whether there were population-specific differences in the suitability of Atlantic salmon (Salmo salar) and brown trout (S. trutta) as hosts for the parasitic glochidium larvae of FPM. We predicted that such differences would depend on the historical occurrence of these salmonid species in FPM habitats. We studied the potential host specificity both in the field and in laboratory by exposing salmo…
The effects of using participatory working time scheduling software on sickness absence: A difference-in-differences study.
Abstract Background Participatory working time scheduling is a collaborative approach to scheduling shift work. As a potential way of improving work time control, it may provide a means to reducing sickness absence in shift work. So far, experimental and quasi-experimental studies on the effects of increased work time control on sickness absence are lacking. Objective To investigate the effects of using digital participatory working time scheduling software on ward-level sickness absence among Finnish hospital employees. Participants and methods This quasi-experimental study compared the amount of sickness absence in hospital wards using a participatory working time scheduling software (n=1…
Elinikäistä osallistumista vai elämää työ edellä? : työikäisten monialaisten palveluiden yhteensovittaminen ja vaikuttavuuden arviointi -loppuraportti
Tavoitteenamme oli tuottaa kokonaiskuva hallinnonalat ja palvelujärjestelmät ylittävästä työikäisten työkyvyn ja työllistymisen tuen palveluiden kokonaisuudesta ja kuvata, miten yhteensovitettavien palveluiden tuloksellisuutta ja vaikuttavuutta voidaan arvioida. Tarkastelimme yhteensovittamista monialaisten palveluiden palveluintegraation, vaikuttavuuden arvioinnin ja systeemisen muutostarpeen ennakoinnin näkökulmista. Aineistoinamme olivat kirjallisuuskatsaukset, asiakkaiden ja asiantuntijoiden haastattelut ja kyselyt, kansalliset rekisterit ja skenaariotyöpajatyöskentely. Tulostemme mukaan työkyvyn ja työllistymisen tuen palveluiden yhteensovittaminen ja asiakkaan tarpeita vastaava palvel…
Risk assessment of gypsum amendment on agricultural fields: Effects of sulfate on riverine biota
Gypsum (CaSO4 ∙ 2H2 O) amendment is a promising way of decreasing the phosphorus loading of arable lands, and of thus preventing aquatic eutrophication. However, in freshwaters with low sulfate concentrations, gypsum-released sulfate may pose a threat to the biota. To assess such risks, we performed a series of sulfate toxicity tests in the laboratory and conducted field surveys. These field surveys were associated with a large-scale pilot exercise involving spreading gypsum on agricultural fields covering 18% of the Savijoki River catchment area. The gypsum amendment in such fields resulted in about fourfold increase in the mean sulfate concentration for a 2-month period, and a transient, …
The Time-Varying Effect of Participatory Shift Scheduling on Working Hour Characteristics and Sickness Absence: Evidence from a Quasi-Experiment in Hospitals.
Participatory shift scheduling for irregular working hours can influence shift schedules and sickness absence. We investigated the effects of using participatory shift scheduling and shift schedule evaluation tools on working hour characteristics and sickness absence. We utilized a panel data for 2015−2019 with 16,557 hospital employees (6143 in the intervention and 10,345 in the control group). Difference-in-differences regression with ward-level clustered standard errors was used to estimate the average treatment effect on the treated coefficients relative to timing of the intervention with 95% confidence intervals (CI). Using participatory scheduling tool increased long working hou…
The effects of using participatory working time scheduling software on working hour characteristics and wellbeing : a quasi-experimental study of irregular shift work
Background: Studies in the health care sector indicate that good work time control is associated with better perceived wellbeing but also with non-ergonomic work schedules, such as compressed work schedules. Participatory working time scheduling is a collaborative approach to scheduling shift work. Currently, there is a lack of information on whether working hour characteristics and employees' wellbeing in irregular shift work change after implementing participatory working time scheduling. Objective: To investigate the effects of using digital participatory working time scheduling software on working hour characteristics and well-being among Finnish hospital employees. Participants and met…
Jokihelmisimpukkapopulaatioiden (Margaritifera margaritifera L.) isäntäspesifisyys
Jokihelmisimpukka (Margaritifera margaritifera L.) eli raakku on yksi kaikkein uhanalaisimmista akvaattisista lajeista Euroopassa. Raakku loisii osan elinkierrostaan lohikaloissa, ja tästä syystä yksityiskohtaista tietoa lajin isäntäspesifisyydestä tarvitaan lajin suojelua varten. Tässä tutkimuksessa tutkittiin kalojen sumputuskokeilla sekä laboratorioaltistuksella, onko raakku sopeutunut eri populaatioissa eri isäntäkaloihin ja onko populaatioissa sopeutumista paikalliseen isäntäpopulaatioon. Lisäksi tutkittiin vierasperäisen puronieriän (Salvelinus fontinalis Mitchill) soveltuvuutta raakkujen isännäksi. Tutkimuspopulaatioiksi valittiin Livojoen raakkupopulaatio, jonka alueella on ennen ve…
Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) differ in their suitability as hosts for the endangered freshwater pearl mussel (Margaritifera margaritifera) in northern Fennoscandian rivers
1. European populations of the freshwater pearl mussel (FPM, Margaritifera margaritifera) have widely collapsed, and despite many types of conservation actions the number of successful restoration trials has remained limited. The goal of this study was to find new aspects for the conservation by investigating whether there are population-specific differences in suitability of Atlantic salmon (Salmo salar) and brown trout (S. trutta) as the hosts for the parasitic glochidium larvae of FPM, depending probably on the historical occurrence of these salmonid species in FPM habitats. 2. We studied the potential host specificity both in the field and in laboratory by exposing salmonid fish to FPM …
