Functional structure of European forest beetle communities is enhanced by rare species
2022
Biodiverse communities have been shown to sustain high levels of multifunctionality and thus a loss of species likely negatively impacts ecosystem functions. For most taxa, however, roles of individual species are poorly known. Rare species, often most likely to go extinct, may have unique traits and functional roles. Alternatively, rare species may be functionally redundant, such that their loss would not disrupt ecosystem functions. We quantified the functional role of rare species by using captures of wood-living (saproxylic) beetle species, combined with recent databases of morphological and ecological traits, from three regions in central and northern Europe. Using a rarity index based…
Global monitoring of soil animal communities using a common methodology.
2022
Here we introduce the Soil BON Foodweb Team, a cross-continental collaborative network that aims to monitor soil animal communities and food webs using consistent methodology at a global scale. Soil animals support vital soil processes via soil structure modification, consumption of dead organic matter, and interactions with microbial and plant communities. Soil animal effects on ecosystem functions have been demonstrated by correlative analyses as well as in laboratory and field experiments, but these studies typically focus on selected animal groups or species at one or few sites with limited variation in environmental conditions. The lack of comprehensive harmonised large-scale soil anim…
Data from: The relevance of ecological status to ecosystem functions and services in a large boreal lake
2015
1. Environmental conventions aim to protect ecosystem structures and functions to provide goods and services for mankind. The degree of aquatic ecosystem naturalness, or ecological status as it is defined in the Water Framework Directive (WFD) of the European Union, is notionally linked to supplies of ecosystem services. In practice these links have rarely been documented or even investigated and, to justify conservation and management objectives based on the status indicators, it is essential to demonstrate their relationships to ecosystem functions and services. 2. The WFD requires member states to classify their surface waters aiming to achieve good ecological status of water bodies. How…
Video-assisted surgery: suggestions for failure prevention in laparoscopic cholecystectomy
2014
Background: Surgery differs from other medical specialties in its execution. It is often complex and includes considerable individual variations. Observing problems in operating theatres (OT) allows for the identification of system failures which should be defined for learning purposes to increase patient safety and enhance general safety culture within hospital organizations. This study evaluates a common video-assisted surgical procedure, laparoscopic cholecystectomy (LC) through failure analysis. The profile of the LC procedure and failure sources is presented. Methods: Data consisted video-observations and interviews concerning twelve LC operations performed at a day surgery unit. All o…
The New Nino Capability Index for Dynamic Process Capability Analysis
2015
The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in-control condition of the process and evaluating suitable capability indices, by assuming the process in-control steady-state condition. However, the in-control period of the process characterizes only a part of the system functioning cycle, the one with the lower defective rate. In particular, the system functioning cycle is also characterized by the out-of-control period, during which a greater defective rate is produced, and such increasing is not considered by the widely adopted capability indices. As consequ…
Przejawy finansyzacji na rynku kredytów dla MSP
2016
Małe i średnie przedsiębiorstwa (MSP) odgrywają od lat kluczową rolę w gospodarkach poszczególnych państw i regionów. Stanowią ponad 99% przedsiębiorstw niefinansowych. O ich doniosłym znaczeniu świadczy nie tylko dominująca pozycja pod względem liczby podmiotów, ale również udział w kreowaniu miejsc pracy czy dochodu narodowego. Kluczowym czynnikiem siły i sukcesu MSP jest dostęp do środków finansowych. Badania wskazują, że MSP napotykają większe trudności niż duże firmy w dostępie do źródeł finansowania. W finansowanie swojej działalności, zwłaszcza rozwojowej, MSP angażują mniej środków finansowych pochodzenia zewnętrznego, szczególnie bankowego. Problematykę tę uznać należy za istotną d…
Audzēkņu instrumentspēles prasmju un ķermeņa darbības pilnveides mijsakarības trombona spēles mācību procesā mūzikas skolā
2015
Trombona spēles pedagoģija bieži vien izmanto paņēmienus un metodes, kas ir pretrunā ar cilvēka ķermeņa darbības fizioloģiskajiem principiem un var gan kavēt un ierobežot instrumentspēles prasmju attīstību, gan radīt kaitējumus mūziķa veselībai. Ārvalstu mūzikas pedagoģijas zinātniskajā literatūrā arvien lielāks uzsvars tiek likts uz cilvēka darbības psiholoģisko un fizioloģisko mehānismu un likumsakarību integrēšanu pedagoģiskajā procesā. Arī trombona spēles prasmju pilnveidi nepieciešams balstīt cilvēka ķermeņa darbības pamatprincipos. Mērķis: izpētīt trombona spēles prasmju pilnveides teorētiskos aspektus un izstrādāt ķermeņa darbības psihofizioloģiskajos pamatprincipos balstītu vingrinā…
