On the Dependence of Cirrus Parametrizations on the Cloud Origin
2019
<p>Particle size distributions (PSDs) for cirrus clouds are important for both climate models as well as many remote sensing retrieval methods. Therefore, PSD parametrizations are required. This study presents parametrizations of Arctic cirrus PSDs. The dataset used for this purpose originates from balloon-borne measurements carried out during winter above Kiruna (Sweden), i.e. north of the Arctic circle. The observations are sorted into two types of cirrus cloud origin, either in-situ or liquid. The cloud origin describes the formation pathway of the ice particles. At temperatures below −38 °C, ice particles form in-situ from solution or ice nuclea…
The SISAL database: a global resource to document oxygen and carbon isotope records from speleothems
2018
Stable isotope records from speleothems provide information on past climate changes, most particularly information that can be used to reconstruct past changes in precipitation and atmospheric circulation. These records are increasingly being used to provide “out-of-sample” evaluations of isotope-enabled climate models. SISAL (Speleothem Isotope Synthesis and Analysis) is an international working group of the Past Global Changes (PAGES) project. The working group aims to provide a comprehensive compilation of speleothem isotope records for climate reconstruction and model evaluation. The SISAL database contains data for individual speleothems, grouped by cave system. Stable isotopes of oxyg…

Phenomenological perspectives on self-care in aging.
2013
Olle SöderhamnCenter for Caring Research- Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayAbstract: Self-care is a central concept in health care and may be considered as a means to maintain, restore, and improve one's health and well-being. When performed effectively, self-care contributes not only to human functioning but also to human structural integrity and human development (ie, to a dynamic and holistic state of health). Self-care as a clinical concept is relevant for health care professionals, and it should be meaningful to investigate it at a philosophical level and to further elaborate upon this concept. The aim of this …
Effects of a brief pre‑admission telephone reminder on no‑show and dropout rates in substance use disorder treatment: a quasi‑experimental study
2022
Abstract Background Appointment no-show and early dropout from treatment represent major challenges in outpatient substance use disorder treatment, adversely affecting clinical outcomes and health care productivity. In this quasi-experimental study, we examined how a brief reminder intervention for new patients before their first appointment affected treatment participation and retention. No-shows (not attending any sessions) and dropouts (discontinuation of initiated treatment because of three consecutively missed appointments) were compared between a period with pre-admission telephone calls (intervention) and a period without such reminders (non-intervention). Methods Participants were a…
Large stocks of peatland carbon and nitrogen are vulnerable to permafrost thaw
2020
Significance Over many millennia, northern peatlands have accumulated large amounts of carbon and nitrogen, thus cooling the global climate. Over shorter timescales, peatland disturbances can trigger losses of peat and release of greenhouses gases. Despite their importance to the global climate, peatlands remain poorly mapped, and the vulnerability of permafrost peatlands to warming is uncertain. This study compiles over 7,000 field observations to present a data-driven map of northern peatlands and their carbon and nitrogen stocks. We use these maps to model the impact of permafrost thaw on peatlands and find that warming will likely shift the greenhouse gas balance of northern peatlands. …

Arbete eller människorelation? : diskurser om närståendevård under social- och hälsovårdsreformen
2018
Suomessa ikääntyvä yhteiskunta ja hyvinvointivaltion rahoituskriisi haastavat nykyisen hoivapalvelujärjestelmän. Tähän haasteeseen pyritään osittain vastaamaan hallituksen kärkihankkeella, jossa kehitetään koti- ja omaishoitoa. Omaishoito asettuu julkisen ja yksityisen, hoivan ja työn välimaastoon ja se koskettaa erityisesti ikääntyneitä ja vammaisia henkilöitä. Kärkihanke liittyy tiiviisti myös sosiaali- ja terveyspalvelu-uudistukseen, jonka tavoitteena on asiakaslähtöiset ja kustannustehokkaat palvelut. Tässä tutkielmassa tarkastelen omaishoidon diskursseja sote-uudistuksen yhteydessä. Pyrin selvittämään mitä diskursseja julkisessa keskustelussa esiintyy, kuinka ne rakentuvat kielellisest…
Evaluation of the ERA5 reanalysis-based Universal Thermal Climate Index on mortality data in Europe
2021
Air temperature has been the most commonly used exposure metric in assessing relationships between thermal stress and mortality. Lack of the high-quality meteorological station data necessary to adequately characterize the thermal environment has been one of the main limitations for the use of more complex thermal indices. Global climate reanalyses may provide an ideal platform to overcome this limitation and define complex heat and cold stress conditions anywhere in the world. In this study, we explored the potential of the Universal Thermal Climate Index (UTCI) based on ERA5 – the latest global climate reanalysis from the European Centre for Medium-Range Weather Forecasts (ECMWF) – as a h…
Results from the Fourth WMO Filter Radiometer Comparison for aerosol optical depth measurements
2018
Abstract. This study presents the results of the Fourth Filter Radiometer Comparison that was held in Davos, Switzerland, between 28 September and 16 October 2015. Thirty filter radiometers and spectroradiometers from 12 countries participated including reference instruments from global aerosol networks. The absolute differences of all instruments compared to the reference have been based on the World Meteorological Organization (WMO) criterion defined as follows: 95% of the measured data has to be within 0.005 ± 0.001∕m (where m is the air mass). At least 24 out of 29 instruments achieved this goal at both 500 and 865 nm, while 12 out of 17 and 13 out of 21 achieved this at 368 and 412 nm,…
