Interesujące gatunki chrząszczy (Coleoptera) z Puszczy Piskiej
2022
W lipcu 2002 roku huragan zniszczył drzewostany na znacznym obszarze Puszczy Piskiej. Część uszkodzonego lasu – 475 ha – pozostawiono bez ingerencji (Las Ochronny „Szast”) – do naturalnej sukcesji. W latach 2005–2021 badano chrząszcze na wybranych powierzchniach pohuraganowych i kontrolnych. Do odłowów stosowano różne typy pułapek (IBL-2bis, Netocia, Moerickego). Uzupełnieniem były odłowy Coleoptera metodą „na upatrzonego” oraz analizy potencjalnego materiału lęgowego chrząszczy. W sumie w trakcie badań wykazano 1000 gatunków Coleoptera. W pracy przedstawiono dane taksonów: rzadkich, reliktów puszczańskich i wymienionych w Czerwonej Liście zwierząt ginących i zagrożonych w Polsce. Ogółem 32…
Missing values in deduplication of electronic patient data
2011
Data deduplication refers to the process in which records referring to the same real-world entities are detected in datasets such that duplicated records can be eliminated. The denotation ‘record linkage’ is used here for the same problem.1 A typical application is the deduplication of medical registry data.2 3 Medical registries are institutions that collect medical and personal data in a standardized and comprehensive way. The primary aims are the creation of a pool of patients eligible for clinical or epidemiological studies and the computation of certain indices such as the incidence in order to oversee the development of diseases. The latter task in particular requires a database in wh…
Identificación de Urgencias por Asma y Enfermedad Pulmonar Obstructiva Crónica en el Servicio de Urgencias de un Hospital. Estudio de Concordancia
1999
ResumenObjetivoAnalizar la concordancia de los resultados obtenidos en la identificación de los casos de asma y enfermedad pulmonar obstructiva crónica (EPOC) diagnosticados en las historias clínicas de urgencias del Hospital Clínico Universitario de Valencia.MétodosEn el contexto de un estudio más amplio sobre la relación entre urgencias por asma y EPOC y determinados factores de riesgo ambientales, se revisaron todas las historias clínicas de urgencias médicas de mayores de 14 años del Hospital Clínico Universitario de Valencia correspondientes a los años 1993 y 1994. Los observadores fueron dos diplomados en enfermería, previamente entrenados en el procedimiento de identificación de caso…
The assessment of parenting in the child welfare practice
1999
Abstract This study analyzed how parenting and factors considered as important determinants of parental care are assessed in the child welfare practice during the placement process, using ethnographic content analysis of case records. The assessment of parenting and the factors affecting it was unsystematic and unplanned with no consistency between cases. The documentary mentions concerning the quality of parent-child relationships were surprisingly rare. The descriptions concentrated more on parents' problems than problems in parenting and the qualities of the parent-child relationship. This study indicated that apart from the need for systematized assessment methods in Finnish child welfa…
Nowe dla Niziny Mazowieckiej i rzadkie gatunki ryjkowcowatych (Coleoptera: Curculionidae) z Kampinoskiego Parku Narodowego
2013
New data on the occurrence of 16 weevil species from the Kampinos National Park are presented, of which 7 species are recorded from the Mazovia Lowland for the first time. Among them two, Otiorhynchus repletus BOHEMAN and Larinus sturnus (SCHALLER) figure in the "Polish Red List".
Wood-inhabiting fungal responses to forest naturalness vary among morpho-groups
2021
The general negative impact of forestry on wood-inhabiting fungal diversity is well recognized, yet the effect of forest naturalness is poorly disentangled among different fungal groups inhabiting dead wood of different tree species. We studied the relationship between forest naturalness, log characteristics and diversity of different fungal morpho-groups inhabiting large decaying logs of similar quality in spruce dominated boreal forests. We sampled all non-lichenized fruitbodies from birch, spruce, pine and aspen in 12 semi-natural forest sites of varying level of naturalness. The overall fungal community composition was mostly determined by host tree species. However, when assessing the …
Entrepreneurship Training and Self-Employment among University Graduates
2012
In economies characterized by low labor demand and high rates of youth unemployment, entrepreneurship training has the potential to enable youth to gain skills and create their own jobs. This paper presents experimental evidence on a new entrepreneurship track that provides business training and personalized coaching to university students in Tunisia. Undergraduates in the final year of licence appliquee were given the opportunity to graduate with a business plan instead of following the standard curriculum. This paper relies on randomized assignment of the entrepreneurship track to identify impacts on labor market outcomes one year after graduation. The analysis finds that the entrepreneur…
Integrating fire-scar, charcoal and fungal spore data to study fire events in the boreal forest of northern Europe
2019
Fire is a major disturbance agent in the boreal forest, influencing many current and future ecosystem conditions and services. Surprisingly few studies have attempted to improve the accuracy of fire-event reconstructions even though the estimates of the occurrence of past fires may be biased, influencing the reliability of the models employing those data (e.g. C stock, cycle). This study aimed to demonstrate how three types of fire proxies – fire scars from tree rings, sedimentary charcoal and, for the first time in this context, fungal spores of Neurospora – can be integrated to achieve a better understanding of past fire dynamics. By studying charcoal and Neurospora from sediment cores f…
Towards understanding the abundance of non-pollen palynomorphs : A comparison of fossil algae, algal pigments and sedaDNA from temperate lake sedimen…
2018
Given the increased interest in non-pollen palynomorphs (microscopic objects other than pollen identified from pollen slides) in palaeoecological studies, it is necessary to seek a deeper understanding of the reliability of these results. We combined quantitative information of algal pigments and sedimentary ancient DNA (sedaDNA) of phylotaxonomical resolution to validate the richness and abundance of fossil algae in the sediment of a small temperate lake. For the first time, fossil and sedaDNA algae data were combined in a composite data-set and used to reconstruct algae turnover rates over the last 14,500 years. This comparison serves as both an example of howfossil algae can be used to a…
Climate Data Records of Vegetation Variables from Geostationary SEVIRI/MSG Data: Products, Algorithms and Applications
2019
The scientific community requires long-term data records with well-characterized uncertainty and suitable for modeling terrestrial ecosystems and energy cycles at regional and global scales. This paper presents the methodology currently developed in EUMETSAT within its Satellite Application Facility for Land Surface Analysis (LSA SAF) to generate biophysical variables from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on board MSG 1-4 (Meteosat 8-11) geostationary satellites. Using this methodology, the LSA SAF generates and disseminates at a time a suite of vegetation products, such as the leaf area index (LAI), the fraction of the photosynthetically active radiation absorbed …
