Cumulative inertia or cumulative stress? Migration behaviour of Finnish graduates
2009
An interesting yet largely unstudied question regarding labour migration behaviour and residence duration is whether migration becomes more or less likely over time. This paper analyses the determinants of residence duration for Finnish graduates. Our results affirm the importance of cumulative inertia as a determinant of migration. The longer a person stays in a region, the smaller are the hazard rates of migration. However, for those graduates who moved to a new region during their year of graduation, the propensity for repeat migration is particularly high during their first three years of residence.
Medical masks and Respirators for the Protection of Healthcare Workers from SARS-CoV-2 and other viruses
2020
The use of medical masks and respirators as personal protective equipment is pivotal to reducing the level of biological hazard to which healthcare workers are exposed during the outbreak of highly diffusible pathogens, such as the recent novel coronavirus SARS-CoV-2. Unfortunately, during this pandemic, supplies are rapidly running out worldwide, with potential consequences for the rate of occupational infections. Also, knowledge about specific characteristics of respirators is of utmost importance to select the proper type according to the clinical setting. A wide variety of literature is available on the topic, but mostly based on Influenza viruses infection models. Clinical evidence on …
Spatially resolved SO2 flux emissions from Mt Etna
2016
Abstract We report on a systematic record of SO2 flux emissions from individual vents of Etna volcano (Sicily), which we obtained using a permanent UV camera network. Observations were carried out in summer 2014, a period encompassing two eruptive episodes of the New South East Crater (NSEC) and a fissure‐fed eruption in the upper Valle del Bove. We demonstrate that our vent‐resolved SO2 flux time series allow capturing shifts in activity from one vent to another and contribute to our understanding of Etna's shallow plumbing system structure. We find that the fissure eruption contributed ~50,000 t of SO2 or ~30% of the SO2 emitted by the volcano during the 5 July to 10 August eruptive inter…
Ocena stanu zdrowotnego drzew w warunkach wybranych siedlisk miasta Kępno
2016
W latach 2012–2013 na obszarze miasta Kępno prowadzono badania, których celem było okre- ślenie stanu zdrowotnego drzew rosnących na 9 wybranych obszarach, o różnych warunkach siedliskowych. Kondycję zdrowotną drzew określano za pomocą skali zdrowotności opracowanej przez J. Dudę. Obserwacji poddano łącznie 210 drzew należących do 26 gatunków występujących w obrębie parku miejskiego, parku 700-lecia, małego parku przy ul. Szpitalnej, alei przy ulicach: H. Sienkiewicza, Dąbrowskiego i W. Sikorskiego oraz skwerów znajdujących się przy ulicach Lipowej, Dąbrowskiego, a także przy ul. H. Sawickiej. Do najliczniej występujących gatunków należały: kasztanowiec pospolity Aesculus hippocastanum stan…
Stan zdrowotny i zagrożenia drzew na terenie wybranych siedlisk miasta Oświęcim
2016
Celem przeprowadzonych badań (w 2011 r.) było określenie stanu zdrowotnego oraz zagrożeń drzew rosnących na terenie Oświęcimia. Analizą objęto 5 obszarów różniących się między sobą warunkami siedliskowymi. Kondycję zdrowotną drzew wyznaczono na podstawie skali zdrowotności opracowanej przez J. Dudę. Badaniom poddano łącznie 424 drzewa należące do 22 gatunków. Najliczniejszymi gatunkami były: lipa drobnolistna Tilia cordata – 16,7% analizowanej grupy drzew i lipa szerokolistna Tilia platyphyllos (15,8%). Najmniejszy udział miał dąb szypułkowy Quercus robur (0,2%). Najwięcej, bo aż 76,2% drzew cechowało się dobrym stanem zdrowotnym, 22,4% złym, a 1,4% bardzo złym. Głównym czynnikiem ogranicza…
Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…
2013
Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…
Monotherapy with indacaterol once daily reduces the rate of exacerbations in patients with moderate-to-severe COPD: Post-hoc pooled analysis of 6 mon…
2014
Summary Background In patients with COPD, exacerbations are associated with poor quality of life and may shorten survival. Prevention of exacerbations is, therefore, a key objective in COPD management. Indacaterol, a once-daily ultra-long-acting β 2 -agonist, has been shown to reduce exacerbations in various studies. This pooled analysis evaluated the effect of indacaterol on exacerbations versus placebo. Methods Six-month data were pooled from three randomized, double-blind, and placebo-controlled studies: indacaterol 300 μg versus placebo (1 year); indacaterol 150 μg and 300 μg versus placebo (6 months); and indacaterol 150 μg versus placebo (6 months). All treatments were administered on…
